Recent findings indicate that the constituting digits of multi-digit numbers are processed, decomposed into units, tens, and so on, rather than integrated into one entity. This is suggested by interfering effects of unit digit processing on two-digit number comparison. In the present study, we extended the computational model for two-digit number magnitude comparison of Moeller, Huber, Nuerk, and Willmes (2011a) to the case of three-digit number comparison (e.g., 371_826). In a second step, we evaluated (...) how hundred-decade and hundred-unit compatibility effects were moderated by varying the percentage of within-hundred (e.g., 539_582) and within-hundred-and-decade filler items (e.g., 483_489). From the results we predict that numerical distance as well as compatibility effects should indeed be modulated by the relevance of tens and units in three-digit number magnitude comparison: While in particular the hundred distance effect should decrease, we predict hundred-decade and hundred-unit compatibility effects to increase with the relevance of tens and units.

Recently, an associative learning account of cognitive control has been suggested (Verguts & Notebaert, 2009). In this so-called adaptation by binding theory, Hebbian learning of stimulus–stimulus and stimulus–response associations is assumed to drive the adaptation of human behavior. In this study, we evaluated the validity of the adaptation-by-binding account for the case of implicit learning of regularities within a stimulus set (i.e., the frequency of specific unit digit combinations in a two-digit number magnitude comparison task) and their association (...) with a particular response. Our data indicated that participants indeed learned these regularities and adapted their behavior accordingly. In particular, influences of cognitive control were even able to override the numerical distance effect—one of the most robust effects in numerical cognition research. Thus, the general cognitive processes involved in two-digit number magnitude comparison seem much more complex than previously assumed. Multi-digit number magnitude comparison may not be automatic and inflexible but influenced by processes of cognitive control being highly adaptive to stimulus set properties and task demands on multiple levels.

Numerical categories such as parity, i.e., being odd or even, have frequently been shown to influence how particular numbers are processed. Mathematically, number parity is defined categorically. So far, cognitive, and psychological accounts have followed the mathematical definition and defined parity as a categorical psychological representation as well. In this manuscript, we wish to test the alternative account that cognitively, parity is represented in a more gradual manner such that some numbers are represented as “more odd” or “more even” (...) than other odd or even numbers, respectively. Specifically, parity processing might be influenced by more specific properties such as whether a number is a prime, a square number, a power of 2, part of a multiplication table, divisible by 4 or by 5, and many others. We suggest that these properties can influence the psychologically represented parity of a number, making it more or less prototypical for odd- or evenness. In the present study, we tested the influence of these numerical properties in a bimanual parity judgment task with auditorily presented two-digit numbers. Additionally, we further investigated the interaction of these numerical properties with linguistic factors in three language groups (English, German, and Polish). Results show significant effects on reaction times of the congruity of parity status between decade and unit digits, even if numerical magnitude and word frequency are controlled. We also observed other effects of the above specific numerical properties, such as multiplication attributes, which facilitated or interfered with the speed of parity judgment. Based on these effects of specific numerical properties we proposed and elaborated a parity continuum account. However, our cross-lingual study also suggests that parity representation and/or access seem to depend on the linguistic properties of the respective language or education and culture. Overall, the results suggest that the “perceived” parity is not the same as objective parity, and some numbers are more prototypical exemplars of their categories. (shrink)

Wales uses languages with both regular (Welsh) and irregular (English) counting systems. Three groups of 6- and 8-year-old Welsh children with varying degrees of exposure to the Welsh language—those who spoke Welsh at both home and school; those who spoke Welsh only at home; and those who spoke only English—were given standardized tests of arithmetic and a test of understanding representations of two-digit numbers. Groups did not differ on the arithmetic tests, but both groups of Welsh speakers read and compared (...) 2-digit numbers more accurately than monolingual English children. A similar study was carried out with Tamil/English bilingual children in England. The Tamil counting system is more transparent than English but less so than Welsh or Chinese. Tamil-speaking children performed better than monolingual English-speaking children on one of the standardized arithmetic tests but did not differ in their comparison of two-digit numbers. Reasons for the findings are discussed. (shrink)

Many theories about human number representation stress the importance of a central semantic representation that includes the magnitude information of small integer numbers, and that is conceived as an abstract, compressed number line. However, thus far there has been little or no direct evidence that units and teens are represented on the same number line. In two masked priming experiments, we show that single-digit and two-digit Arabic numerals are equally well primed by an Arabic numeral with the (...) same number of digits as by an equally distant Arabic numeral with a different number of digits (e.g. the priming effect of 7 on the target 9 is the same as the priming effect of 11 on the target 9). The finding was obtained both with a number naming task and with a parity judgement task. This is in line with the hypothesis that units and teens are part of a continuous number line. (shrink)

Early number skills represent critical milestones in children's cognitive development and are shaped over years of interacting with quantities and numerals in various contexts. Several connectionist computational models have attempted to emulate how certain number concepts may be learned, represented, and processed in the brain. However, these models mainly used highly simplified inputs and focused on limited tasks. We expand on previous work in two directions: First, we train a model end-to-end on video demonstrations in a synthetic environment (...) with multimodal visual and language inputs. Second, we use a more holistic dataset of 35 tasks, covering enumeration, set comparisons, symbolic digits, and seriation. The order in which the model acquires tasks reflects input length and variability, and the resulting trajectories mostly fit with findings from educational psychology. The trained model also displays symbolic and non-symbolic size and distance effects. Using techniques from interpretability research, we investigate how our attention-based model integrates cross-modal representations and binds them into context-specific associative networks to solve different tasks. We compare models trained with and without symbolic inputs and find that the purely non-symbolic model employs more processing-intensive strategies to determine set size. (shrink)

Are small and large numbers represented similarly or differently on the mental number line? The size effect was used to argue that numbers are represented differently. However, recently it has been argued that the size effect is due to the comparison task and is not derived from the mental number line per se. Namely, it is due to the way that the mental number line is mapped onto the task-relevant output component. Here synesthesia was used to (...) disentangle these two alternatives. In two naming experiments a digit-color synesthete showed that the congruity effect was modulated by number size. These results support the existence of a mental number line with a vaguer numerical representation as numbers increase in size. In addition, the results show that in digit-color synesthesia, colors can evoke numerical representation automatically. (shrink)

We compared two digital humanities methods in the analysis of a contested scientific term. “Epigenetics” is as enigmatic as it is popular. Some authors argue that its meaning has diluted over time as this term has come to describe a widening range of entities and mechanisms (Haig, International Journal of Epidemiology 41:13–16, 2012). Others propose both a Waddingtonian “broad sense” and a mechanistic “narrow sense” definition to capture its various scientific uses (Stotz and Griffiths, History and Philosophy of the Life (...) Sciences 38:22, 2016). We evaluated these proposals by first replicating a recent analysis by (Linquist and Fullerton, Theoretical Medicine and Bioethics 42:137–154, 2021). We analyzed the 1100 most frequently cited abstracts on epigenetics across four disciplines: proximal biology, biomedicine, general biology, and evolution. Each abstract was coded for its heritability commitments (if any) and functional interpretation. A second study applied LDA topic modelling to the same corpus, thus providing a useful methodological comparison. The two methods converged on a discipline-relative ambiguity. Within such disciplines as biomedicine or molecular biology that focus on proximate mechanisms, “epigenetic(s)” refers to a range of molecular structures while specifying nothing in particular about their heritability. This proximal conception was primarily associated with the functions of gene regulation and disease. In contrast, a second relatively uncommon sense of “epigenetic(s)” is restricted to a small proportion of evolutionary abstracts. It refers to many of the same molecular structures, but regards them as trans-generationally inherited and associated with adaptive phenotypic plasticity. This finding underscores the benefit of digital tools in complementing traditional conceptual analysis. Philosophers should be cautious not to conflate the relatively uncommon evolutionary sense of epigenetics with the more widely used proximal conception. (shrink)

In the context of digital monetary market integration, the importance of cross-border digital currency research is receiving prominent attention. This study integrated Extended Unified Theory of Acceptance and Use of Technology (UTAUT2) and initial trust factors (ITM) into an integrative framework, which synthetically complemented the objective measures and subjective insights of digital currencies. The results indicated the integrated framework, which verified its robustness predicting the acceptance and recommendation intention of digital currency. By analyzing the two different features of digital currencies, (...) this research puts forward a set of targeted solutions to ensure that users of Chinese and Korean digital currencies make a long-term policy for the sustainability, eventually benefitting the cross-border digital monetary transactions and economic cooperation in Asia, which leads the world to the sustainable development in the digital currencies field.

It is not understood how the numbers and identities of vertebrae are controlled during mammalian development. The remarkable robustness and conservation of segmental numbers may suggest the digital nature of the underlying process. The study proposes a mechanism that allows cells to obtain and store the segmental information in digital form, and to produce a pattern of chromatin accessibility that in turn regulates Hox gene expression specific to the metameric segment. The model requires that a regulatory element be present such (...) that the number of occurrences of the motif between two consecutive Hox genes equals the number of segments under the control of the anterior gene. This is true for the recently discovered hydroxyl radical cleavage 3bp-periodic (HRC3) motif, associated with histone modifications and developmental genes. The finding not only allows the correct prediction of the numbers of segments using only sequence information, but also resolves the 40-year-old enigma of the function of temporal and spatial collinearity of Hox genes. The logic of the mechanism is illustrated in the attached animated video. How different aspects of the proposed mechanism can be tested experimentally is also discussed. (shrink)

Reading numbers aloud involves visual processes that analyze the digit string and verbal processes that produce the number words. Cognitive models of number reading assume that information flows from the visual input to the verbal production processes—a feed‐forward processing mode in which the verbal production depends on the visual input but not vice versa. Here, I show that information flows also in the opposite direction, from verbal production to the visual input processes. Participants read aloud briefly presented multi‐digit (...) strings in Hebrew, in which the order of words is congruent with the order of digits (21 = twenty‐and‐one), and in Arabic, in which the ones word precedes the tens word (one‐and‐twenty). The error‐by‐digit‐position curve was affected by language: relative to Hebrew, in Arabic the error rate was slightly lower for the unit digit and slightly higher for the decade digit, indicating that in Arabic the unit digit was processed earlier and the decade digit later, in accord with the Arabic word order. This language‐dependent processing order originated in the visual level and was not a verbal confound, because it persisted even when I controlled for the serial position of the decade/unit word in the verbal number by using numbers with 0 (two hundred three/two hundred thirty). I conclude that the visual analyzer's digit scanning order, decade‐first or unit‐first, is not fixed but affected by the language in which the number is produced—a top‐down, verbal‐to‐visual information flow.

Sleep spindles are frequently studied for their relationship with state and trait cognitive variables, and they are thought to play an important role in sleep-related memory consolidation. Due to their frequent occurrence in NREM sleep, the detection of sleep spindles is only feasible using automatic algorithms, of which a large number is available. We compared subject averages of the spindle parameters computed by a fixed frequency (11-13 Hz for slow spindles, 13-15 Hz for fast spindles) automatic detection algorithm and (...) the individual adjustment method (IAM), which uses individual frequency bands for sleep spindle detection. Fast spindle duration and amplitude are strongly correlated in the two algorithms, but there is little overlap in fast spindle density and slow spindle parameters in general. The agreement between fixed and manually determined sleep spindle frequencies is limited, especially in case of slow spindles. This is the most likely reason for the poor agreement between the two detection methods in case of slow spindle parameters. Our results suggest that while various algorithms may reliably detect fast spindles, a more sophisticated algorithm primed to individual spindle frequencies is necessary for the detection of slow spindles as well as individual variations in the number of spindles in general.

Muslims are fundamentally interested in the practice of writing especially for scribing the copies of the Qur’ān. Later, the practice of scribing ḥadīths texts and writing diplomatic correspondence increased the demand for developing this practice. It is because the writing is based on a religious reference in Islamic societies; over time, the interest in writing and writing materials has also turned into an art form. Thus, writing and writing materials have been named with the selected words from the Qur’ān. Pencil, (...) book, pages (ṣuḥuf), line, stone tablet (alwāḥ) are some of the examples of those words. The writing constituted a series of professions. Calligraphers and warrāqs (book dealers/booksellers) are some examples in Islamic societies. Until the printing press became widespread, the books were written and reproduced by hand which is called istinsākh. Nowadays, these manuscripts are protected in libraries and digital archives. Codicology examines the external elements of these manuscripts such as ink, binding and paper. In addition, the critical edition method was used to bring out manuscripts to the surface. Critical edition of manuscripts is not only transferring the text to the computer. The critical edition is to compare manuscripts of work to reach the original text of the author. While doing this, the evaluation of the text has been held to reveal the historical value of it. In this article, the place of manuscripts in Islamic culture has been discussed and the basic principles of the critical edition, how to create the editing (dirāsa) and text (naṣṣ) sections of the critical edition are explained with examples. The examples were selected from the previous critical editions conducted by the author. This study aims to give an introduction to a very wide field of codicology and critical edition. This article is intended to provide basic information for researchers interested in codicology and critical edition.Summary: Classical Islamic writing culture has its method. For centuries, Muslims have written manuscripts according to this method. This method has been applied from writing the knowledge on paper to collecting and binding the fascicles.The adventure of creating a manuscript is a long process. A lot of people come around to contribute this process initiating from the writing of the first sentence. Producer of the knowledge: scientists, paper-producer: werrâq, the calligrapher: khaṭṭāṭ, bookseller, bookbinder, expert in the ink, naqqāsh who marbles the papers, sponsors of the project, collection and the librarian are some of the contributors. Today, this adventure continues with the participation of enthusiasts which are: the author who re-writes the manuscript to revive it, the restorer who repairs the damage of the manuscript, the expert who creates the digital copy and institutions which publishes the facsimile.Nowadays manuscripts are accepted as important scientific data and are examined in many ways other than their contents thus new specialities have been occurred. At universities, the institutes which examine manuscripts have been established and academic journals have been published. Moreover, the critical edition of manuscripts is the main subject of some of the M.A. and Ph.D. theses.The studies on critical edition, which initiated earlier in some of the western countries, have made a rapid development and created its method. In Turkey, there are many critical editions of works which are based on various manuscripts from Theology to Literature fields. However, there is no significant mutual method among the studies yet. Also, their understanding of critical edition differentiates. In those studies, it has to be examined that basic parameters such as the selection of convenient copy, access to all copies of manuscript or priority of copies are applied to critical edition process. Most of the time it is observed that the advisor’s way of the critical edition has shadows on studies. However, fundamentally critical edition process needs expert contribution itself. Difference between studies is related to the fact that the critical edition is relatively a new field of study in Turkey. Therefore, specific studies in the field of critical edition and codicology are still needed to be developed. On the other hand, there are various publications to establish an objective methodology of the critical edition. Significant studies are being held by the Center for Islamic Studies (ISAM) to establish a mutual language and method for critical edition studies. The factor that led to the emergence of this article is the effort to contribute to the realization of this method. The article discusses the principles to be followed during a critical edition process. Moreover, topics are explained practically with examples selected from manuscripts. Those examples have been chosen from the author’s previous critical edition works. The article would be considered as an “Introduction to Critical Edition” for the researchers who are new at this field. In this respect, the article aims to make a methodological contribution to the critical edition studies.There are many parts of a manuscript –something more than the written text on the page– which makes it a whole. These parts can be divided into internal and external elements of the manuscript. All of these are parts have different levels of contribution to the examination of the critical edition of the work and the interpretation of the texts.Some external elements of manuscript are: ink production and color, inkwell, production of paper, foliation, rule-borders, and frames, ruling board (misṭara), sewing of quires, gilt and gilding, bookbinding, stamping and tooling, frontispiece, cases and pouches, storage boxes and cabinets, flap, tabula ansata, the history of manuscript.The internal elements of the manuscript are: text of the manuscript, script, subject, authenticity, historical value and importance, proprietor, literary features, number of copies and textual variants, scribes and copyists, whether it has been falsified or not, sources used or referenced by the author, abbreviations, records of marginalia, colophon, glosses and scholia, ownership statements, seals and seal impressions, word transposition or transposition of words/letters, waqf-statements, correction signs and corrections, countermarks.While the internal elements of manuscript are the work of critical edition, the external elements of the text fall within the field of codicology. Although critical edition and codicology are considered as separate sciences, there are points where they can contribute to each other. For instance, the ink tone or binding style of a manuscript may help to determine the writing date range of it. The references used by the manuscript can give us an idea about the name or the subject of another manuscript. The literary characteristics of the manuscript may reflect the author's success in language and literature fields. Thus, we are able to inform that the critical edition process of a manuscript requires the evaluation of substantial information at the same time which is no different from an archaeologist carefully examining an arrowhead. Therefore, whatever is the relation between History and Archeology has; Islamic sciences have the same relationship with critical edition. They are both individual sciences with methods of their own and two inseparable common sciences. Thus, without the contribution of codicology or other sciences, rewriting a manuscript on a computer does not mean making a critical edition of it. According to this information, we can define the critical edition as follows, “Critical Edition is the process of reviving of any manuscript -which belongs to Islamic civilization- with comparison of all available copies to create a single text which is closest to the text of the author and to determine the sources which this main text is based, citations such as verses, hadiths and poetry.”For studies on critical edition, the priority should be given to the texts which will contribute to this science. Before initiating critical edition, the authenticity of the author of the manuscript should be determined precisely. Of course, having a person's name on the page is not enough for determination. All copies of the manuscript must be identified. From those copies, critical edition should be based on the text that the author has personally written or prepared as a draft and other copies should be compared with this. In the absence of the author’s authentic copy, new criteria will apply. For instance, the copy written by the closest student of the author or the copy with the closest writing date takes precedence over the copies with no date. After comparison of all copies, the differences are shown in the citation.Critical Edition consists of two sections entitled as Edition (Editing/Dirāsa) and Text (Naṣṣ):The Edition section includes: the author’s name, lineage, place and date of birth, scientific life of the author and his/her prominent students, works, the authentication document which is proven that the text is belong to the author, the place of the work in the history of science, studies about the work, bibliography, literary characteristic, terms in the text, the amount and characteristics of the copies, the characteristic of the main copy which is determined as the fundamental text for the research, the rules and principles applied during the critical edition, the digital images of the first and last pages of the copies used. The Edition section is the part that demonstrates the reliability of the study. All external elements of writing are being introduced here. The importance of the text is confirmed by this edition process. Thus, the final shape of the edition section must be shaped by reading and understanding the text.In the text section, the main aim is to reach the very first text which has been written originally by the author. In this section, principles of morality and objectivity are followed. The text is preserved; additions or subtractions are not made. Cited sources at the manuscript are being found. Verses and ḥadīths are written with their sources. Poems are found in Dīwāns. Text is made legible with punctuation and pilcrow. Proper names, dates of death are written together. Page numbers in the manuscript are shown in square brackets. Some simple grammatical errors are corrected without interfering with the main text. Mostly the reason for this is the letters used for men or women. At the end of the study, a bibliography with all the resources used during the critical edition process is added. The Islamic codicology and manuscripts appear to receiving interest especially in academic studies. Considering that many manuscripts from the Ottoman Era are still waiting to be revived thus, we may come across profound critical edition works in the near future. Therefore, it is understood that individual studies related to the manuscript itself and the method of the critical edition will guide the researchers. (shrink)

In this research we focus on ethnic minorities, one of the underserved groups in Europe. In particular, we address the internet use of Turkish ethnic children, aged 9 to 16, in several EU countries. We examine the extent to which they can be considered digitally disadvantaged when compared to the majority population in those countries. We also compare Turkish children living in Turkey to those in the diaspora as well as to the majority children living in those same European countries. (...) The data used for this analysis is part of the EU Kids Online research. Of the three groups of teenagers examined, those in the Turkish diaspora take a position in between their native European peers, who are the most fervent surfers on the internet, and the Turkish children living in Turkey, who use the internet least often. Generally speaking that is also true for online competencies and online activities. As far as exposure to online risks is concerned, European majority children are more familiar than the two other groups with receiving sex-related images and messages and with face-to-face meetings with online contacts. By contrast, children in the Turkish diaspora are relatively more familiar with cyberbullying. (shrink)

Multicultural environments require learning multiple number notations wherein some are encountered more frequently than others. This leads to differences in exposure and consequently differences in usage between notations. We find that differential notational usage imposes a significant neurocognitive load on number processing. Despite simultaneous acquisition, forty-two adult binumerate populations, familiar with two positional writing systems namely Hindu Nagari digits and Hindu Arabic digits, reported significantly lower preference and usage for Nagari as compared to Arabic. Twenty-four participants showed significantly (...) increased reaction times and reduced accuracy while performing magnitude comparison tasks in Nagari with respect to Arabic. Functional magnetic resonance imaging revealed that processing Nagari elicited significantly greater activity in number processing and attention networks. A direct subtraction of networks for Nagari and Arabic notations revealed a neural circuit comprising of bilateral intra-parietal sulcus, inferior and mid frontal gyri, fusiform gyrus and the anterior cingulate cortex (FDR p<0.005). Additionally, whole brain correlation analysis showed that activity in the left inferior parietal region was modulated by task performance in Nagari. We attribute the increased activation in Ng to increased task difficulty due to infrequent exposure and usage. Our results reiterate the role of the left intra-parietal sulcus in modulating performance in numeric tasks and highlight that of the attention network for monitoring symbolic notation mode in binumerates.

Introduction Ben Segal What interests me is instigated language, language dishabituated from its ordinary doings, language startled by itself. I don't know where that sort of interest locates me, or leaves me, but a lot of the books I see in the stores (...) seem to lack language entirely. Gary Lutz (2006). This issue of continent.'s fiction section features a reprint of “This Is Nice of You” from the first edition of Gary Lutz's collection I Looked Alive . That book was originally released by Four Walls Eight Windows in 2003 and has since been reissued in 2010 by The Brooklyn Rail/Black Square Editions. Calamari Press has also reissued Lutz's Stories in the Worst Way (originally published by Knopf, largely forgotten and dismissed, and then re-issued by the too-short-lived 3rd Bed). “This Is Nice of You” was edited for the re-issue of I Looked Alive and, as the original book is out of print, the earlier version of the story has been hard to come by for some time. This initial version is a bit longer than the new version—Lutz is a master of tightening down his texts to their most linguistically intensified cores—but it is in no way sloppy. It is a great privilege for continent. to be able to make available rare texts of (first) aesthetic and (second) scholarly value. For those readers unfamiliar with Gary Lutz, I believe this story will serve as a worthy introduction. Like Raymond Carver, Diane Williams, Christine Schutt, and so many other important twentieth century and contemporary short story writers, Lutz studied with and was edited by Gordon Lish. This connection is apparent in his attention to sound and the sentence as compositional unit, but Lutz's is a unique voice. “This Is Nice of You” bears Lutz's trademark torqued and turning syntax, his sexed-but-nameless characters, his rendering of the human body and its emissions as utterly discomfiting. Lutz's preoccupations with the mundane raise ordinariness, via startling language and observation, to grandiosity and grotesquery. In the fall of 2008, Lutz delivered a lecture entitled “The Sentence is a Lonely Place” to writing students at Columbia University. The lecture was later printed in The Believer (and is linked below). In it, he spoke about the importance of the sentence as a compositional unit, as even the distinguishing formal characteristic of prose. Specifically, Lutz explained that, from Lish, he had developed a "poetics of the sentence." Accordingly, Lutz constructs his stories at the level of the sentence, paying extreme attention to the material of words- their letters and their sounds- and the way they abut one another and interact on this material level even before they are employed in the service of traditional aims of fiction like meaning or story. Lutz often uses a(n almost constraint-related) technique called consecution. Letters or sounds from one word are carried forward into the following, producing drama and movement in the language itself at a level entirely apart from that of plot. For example, you can see how the 't's in the first sentence of “This Is Nice of You” repeat fast and hard through met and then soften into the 'th's of brothers and they. This close attention to the specific material and characteristic conditions of prose means that Gary Lutz's work always involves both a happening in language and of language. “This Is Nice of You” has a richness and depth that is hidden not in symbolism or obscure reference but on the surface of the page, in the language of every sentence.

Taylor, Justin. “ An Interview with Gary Lutz .” Bookslut. July, 2006. Web. THIS IS NICE OF YOU [156] [1] I was a man dropping already well through my forties, filthy with myself, when, taking a turn at the toilets one afternoon, I met two brothers-they said they were brothers-who swore they had a sister, a schoolteacher, an officer of instruction at the county college, a whirlwind midlife turmoil of everything already put to ruin, who had gone off from a new marriage in an old car, an upkept and ennobling sedan, but had returned now to the apartment and [157] was living there alone with the little runoff there was from the marriage-some outcurved appliances, apparently, and low-posted furniture promoting its own mystery but becoming figurable in certain concentrations of TV light-and, above all, a telephone (on a pedestal, they insisted), the handpiece of which she gripped in lieu of exercise, or in fury, and I thus let out my little, reliable cry that I was in fact a student of the telephone, that it was a debasing apparatus in the main, with its meager economy of bells and tones, and the intimacy of the mouthpiece that sent your breath, tiny aftervapors of it, back toward your lips, so that regardless of the party accepting the outgoing products of your voice, you were, at most, in a further, rivaling exchange with yourself alone, and this is what must have brought the two of them around, the men who proclaimed brotherhood with the woman, because they offered me her phone number, put it at my disposal on a piece of paper one of them had already committed it to, a tearing from a menu, and the looks the men were now giving me had deletions in them, already, of my exact, beanpole shape and size. So off I went to a pay phone, the nearest canopied one I could find. The woman answered after the second ring and said she needed a lift right that very moment into the little, unlevel city close by. She was idling in the doorway of the building when I pulled up in front, and I helped her into the car, then got back in myself. I had always had a way of not having to look at people that nonetheless brought them to me in full, and so I still am certain of the susceptive and impressible comp-[158]lexion, the shimmer on the mouth, a lipstick of low brilliance, a difficulty around the eyes, the hair short and rayed out exclamation ally, skin bagged up over the elbow bone, conflict even in how her arms stayed at her sides—in sum, a spinal loveliness for me, an off-blonde quantity with shadowed, thumbworn hollows that put me out of as much as I might have ever known of women before. I set the two of us into the narrow traffic, and I remember telling her, by way of explaining the little burden which I had shifted, by now, from the shelf of the dashboard and onto my lap, that when you lived in filth, as I then did, a daily newspaper came to count for a lot, although instead of the thick-supplemented local paper I bought a trimmer one from a backlying town—not, of course, for any affluences of native data it carried, but as an article of house ware: a rough immaculacy in four lank sections, a set of fresh, hygienic surfaces to come between the table, say, and whatever I had going for me at the table, if the table was where I was going forward—because what else so cheap comes so clean and far-spreading? The woman told me that her own trouble with paper was that through a modest hole, no larger than a quarter, that had been drilled a foot or so above the floor (the standard height, she had reasoned, of legitimate electrical outlets), and by means of which her faculty office had at last gained communication with the roomier but unoccupied office next door, more and more often shot a single sheet of paper, plain copier paper she had rolled just barely into a tube, [159] so that after landing on the floor of the neighboring office the paper would preserve little if any of the curl, and there would be nothing written or typed on it, of course, and it was always a blank sheet that had been ageing on her desk for some time and had already been moved around, or advanced, from station to station on the desktop, coming into further creaselets and crimps and other infirmities—paper, in short, still too bare and unfraught to be thrown responsibly and forgettably away, and yet too seasoned and beset with irritations of the surface (a molelike blemish, say, or what looked like a tiny hair, an eyelash, sunk into it, or frecklings, or notational pressings of a fingernail), too wrought, in sum, for the paper to be appointed to any secure curricular purpose. Her office, she claimed, was in fact full of such paper, much-handled and singularized sheets of it by the loose, functionless hundred. I had to get it across to the woman that I myself no longer had an office, or any other place to divide me reliably from everybody else, and that for much of the daylight I thus appeared to be among people because I kept putting myself where people came together into even closer-fitting assortments, the viewing areas and showrooms and rotundas and such: I took in the lean-to look of the women, the tongues coming and going in what the men kept thinking of to say—whole families of low knees for me to bark my shins against during the crowded and involving way out. At home afterward, in the one room where my life was packed down, I would keep my nose stuck in the safehold of the phone [160] book, where the names of people suffered reduction to mere episodes of the alphabet and underwent humbling declensions down every column (Lail, Lain, Laine, Lainerd), and he names of streets, of the towns and townships, got docked in crude, heedless abbreviations (the vowels almost always the first to get poked out), and I would run my eyes over the telephone numbers themselves, each sequence of digits another fallible run of the infinite. I thus corrected my feelings for people and assembled myself emotionally into whatever else I had at hand—the obligating arms of the clothes hangers, usually, or the keen-angled understructure, the guardian legginess, of the ironing board. The woman said that in her case, though, it was more a matter of making slow circuits of the classroom where she had to put across the Emporial Sciences, retail theory and methods, to heat-giving and suggestive young women, some of them world cruelties already. There was the cooing of empty stomachs in the hour just before lunch, and the braying and fizzle of loaded stomachs in the low hours of the afternoon. She would recite her notes in a voice barely loyal to anyone octave, a tiny alluvium of slaver hardening at the corners of her mouth on the days she gave the glassy lozenges a slow, warming suck, and she would take lowering notice of how whatever she said succumbed at once to freak spellings and razzing paraphrase in the big, dividered notebooks; and because in midafternoon light the world looked as thorough, as filled in, as it was ever going to get, a better way to set about ruining her eyes was to review how hair had [161] established itself on the arms of the young women, because almost every arm had brought across itself a welcome and diversifying shadow. On one girl it would be a fine, driftless haze afloat above the white of the arm, never seeming to touch down on the skin itself. (An atmosphere, at most, of chestnut brown.) On another, it was as if copper wire, the narrowmost lengthlets of it, had been stuck into the fleshy batter of the thick, freckled forearms. On a third: a field of it–wheat-colored, thin-spun. On a fourth; a differencing, darkish updrift that shaded off as it approached the inner bend of the elbow, then re-emerged at the base of the upper arm as whiskery fringe. On others it was a brassy or rust-colored frizz, or it was as coarse as cornsilk, or it looked fussed on, as if the arm had been slowly stroked with charcoal. But here the woman broke off, or I may well have made an interruption of my own—I think I must have asked whether she was hungry, and she said if I was, and so on one of the lesser streets I parked the car and led her down into a belowstairs eating house I still remembered. Sandwiches were presently lowered in front of us. I watched her remove the festooned toothpick from hers and then play her fingers over the toasted planes before she took a fond first bite. "This is nice of you," she said. I must have looked at her in the way I then had of getting people to speak so they would not seem to be dwelling any longer on my features, because if on the well-set face the mouth and eyes are said to seem frozen in elegant orbit about the til) of the nose, then mine was a face that behold-[162]ers, regarders, could not help trying to round off with greater success, to goad the particulars of it back into the arcs they had wandered away from—the mouth, for instance, having been pursed and pinched suchwise that it seemed resident more on one side of the face than the other—and there were other signs of original strife to be busied with (slapdash eyebrows unbunched, it appeared, from reserves of hair elsewhere on my person; a showing of adult acne, a shrivelly little relevance of it, confined to the declivity of my nose); and so to be polite, the woman thus sank her gaze into her sandwich, and told me, in a voice lowered accordingly, that, one late-childhood summer, she had devoted herself to collecting postage stamps: it was a tongue-involving sideline to early-arriving puberty, and she liked having to lick the pale, gummed hinges instead of the sticky backs of the stamps themselves before entering everything into the hosting album; and once, during some foul weather between her and a brother (the older, thrown-over one, who had already made a habit of fooling the underside of his arm across the top of hers and calling her "pussified"), she reached for the shoe box in which she had let duplicate stamps accumulate—Spanish ones, mostly, of a fading orange—and sent the box slooshing through the lower air so that the stamps showered onto the brother's bare legs with a full, delicate harm. The woman was now touching up the surface of her iced tea with tiny activities, initiatives, of the longspun spoon. I myself was good at getting my touch onto things, although in a way that seemed to mix up the motive atoms inside [163] them, but I was satisfied that for the moment my sandwich, the unbitten-at half of it, was displayable and fit and local to my plate. The woman went on to say that, as a child, she had been bundled off, many an afternoon, to the slope-ceilinged quarters of a bachelor uncle who, when speaking of anybody not immediately present, could not bring himself to use the person's name but instead would say "an acquaintance of mine in ..." and then mention the name of some lapsed homeland, or little-loved rural orchestra, or backset building about to come down; and it was never a riddle, this device of his (not once could the girl have been expected to identify any of the subjects), and no matter how often and aloud he insisted that particularizing persons any further—bringing even a first name down upon anyone of them—would have been indecent, he claimed, much like doing things to people while they slept, the girl accepted all of the uncle's prim and extravagant evasion for what he surely must have intended it to be: a neat, protective trick to space the world out a little further in her favor, to scatter the population so that wherever her hand might at last come down, it would have to be on herself alone. And here I could sense that the woman wanted from my mouth an account of as much as I myself might have ever managed of attachment, so I told her I had once owned a house (a rising, really, of much-fingered, handwrought architecture that amounted to a little family of rooms above garages: a boxlike building with a rattly thorax of downspouts [164] and drainpipes and an unfolded but full-toned fire escape), and I had had for a time a boarder, a student, a high-colored, loose-packed representative of declining girlhood, hung with necklaces and barrettes, a girl of precise but shifting leanings and inclinations; and the afternoon she had come round to ask after the room, I stood in the entranceway, handshaken and asweat, and from what would later be my memory of the girl, I made off with, first, how every pore of her nose seemed to be sheltering within itself a tiny dark seedlet, a grain of something immediately, enormously valuable. And an almost lipless mouth (just a slit, practically), the teeth inside looking wet, watered-it was my life's chore, at that instant, to keep from sending the back of my thumb blotterlike across the line of them (I was later to learn she drank everything cold and through the narrowest of straws). And her hair: it was tea-colored hair she had, long and reachful, an unstopped downcome of it. Tall for a girl, but she managed to stay out of much of her height and put herself across as somebody backward, or behind. I must have told the girl, as best I could, that I of course had a wife, a full-faced, imperishable partner, though for the moment she was gone otherwhere in the marriage, and here the woman, my present companion, my tablemate, whose feet were now parked, in parallel, on the grade of my upper leg, interrupted to say that her husband, too, had been such a liar, and what could I bring up by way of reply other than that a lie is a truth struck through with other, further truth, or that a lie is the present multiplied by the past or that a lie [165] is an outcry of borrowed hope? The woman gave me an allowed look of disgust, her eyes lowered but still popular with me, and on I went with what had now become the girl of my story. For there had been a great, gainful carpet in the room I put the girl into, a matty expanse of coarse, grabby piles, an engrossing affair that took things into itself and held them tight, misered them, and I of course insisted that the girl not bother herself with its upkeep, that I enjoyed weekly access to a prestigious, upstanding vacuum cleaner; but no sooner was the girl out of the house each morning than I would withdraw from my room, where time was unportionable, and loose myself into the ticktock impertinence of the girl's room and get down on my knees, and, going after the carpet first with my fingers, then with a forceps, and finally by unspooling lengths of clear package-sealing tape and pressing them against the tufts in neat rectangles to catch what I might have missed, I brought vast tracts of the carpet to depletion, recovering not simply the girlinesses, the girleries, one would expect (buttons, straight pins, downed jewelry), but flirtier personalia in the form, say, of a stray confetto brought into the world when a page had been wrung with out caution from a spiral-bound notebook, or some pleated paper shells of the chocolates she required, or one of the bargain antihistamines she took to get her naps going, or a trash-bag tie ragged enough to show the kinked line of the wire within (this I would get wound around my finger), or a cough drop enwrapped like a bonbon (I would undo the [166] wings of the wrapper and have to decide whether to suck the drop all down or begin chewing it midway)—I became the following, the public, that these things, these off-faIlings, had come to have; but mostly there was hair, afloat above the uppermost pushings of the fabric of the carpet an almost continuous haziness of loose hairs of all lengths and sources, and I would have to set them out on a fresh sheet of paper and assort them according to the regions of the body they had taken their departure from, and in no time I had nest-like filiations of broken filaments and smaller involvements of the hairs that made me think of hooks, of barbs, of treble clefs, and each pile required a separate envelope, to be filed in a separate shoe box for every sector of the body until, I hoped, the boxes themselves would no longer be enough and I would have raised something semblable, brought up something equal in volume to the comprehensive girl herself. And her wastebasket! For every bit of rubbish, every dreariment she tossed into the thing, I would, in secret, deposit a reciprocal discard of my own, matching a spotted, confessory tissue of hers with a lurid throwaway after my own heart–the cardboard substructions of a fresh parcel of underwear, maybe, or tearings from pantyhose I now and again pressed against a span of my forearm to work onto it the complications of female shading I otherwise made do, choosily, without. I thus built the two of us up together in her trash! One afternoon-it was another of those lifeful, unsam-[167]pled days on which the world humors us each a little differently to keep us nicely on our last legs—I discovered in the wastebasket an inch-deep textbook of hers, a paperback with a celery-colored cover that had come partly unglued, and this dilapidation I paired off, naturally, with a name-your baby guide to whose pages, during my recurrent turnings of them, in bed or at table, I had contributed dried produces of my person, a chemical splendor entirely mine. This coupling sent a sudden spigoty thrill from me that forced an unbuckling and an unzipping and a cleanup with a handkerchief I then ventured responsively into the wastebasket as well. It was in the bathroom afterward that I found a suds-clouded puddle on the unlevel floor of the tub, a little undrained remainder, rimmed with offscum, of the girl's prolonged early-morning soak, and this was as much as I needed to get on my hands; I pressed them flat against the wet porcelain, then flapped them around in the air, and that was when I noticed it—in the amphitheater of the toilet bowl, an orange-yellow tint, or value, to the waters. When the girl arrived home that evening, I told her, of course, that I had discovered fresh, unforeseen trouble within the tank of thelet (a misalignment of the trip lever, a waywardness of the float ball, a ulation of the lift wires, kinks and defects, really, throughout the entire system) and that in fine it was an apparatus now operable only by means of advanced and strenuous equilibrial manipulations that it would be unseemly, inhospitable, of me to pre-[168]sume to burd to burden her with–so that from here on out, following any leak or evacuation she need merely lower the lid and then, before quitting the room, ring the handbell that had been placed on the would seeeverythinghing else. But the bell never rang, not even once, and from my window the next morning I watched the girl carry from the house a little plastic bag distended balloonishly, much like those bags you will remember having seen in the hands of children bearing homeward their solitary carnival-prize goldfish. In fact, I never ran across the likes of the girl again. The man who came to collect her things-not the father, apparently, but an advocate, an upholder-l found to be dull-eared and lax in his speech, and the better part of his face seemed to have already begun making tiny, rotational departures from whatever it was that the eyes, themselves impressively mobile, were just that moment having to take in. (Was there a lamp in the house that was not that night slopping its wattage over everything?) I guess I was waiting for the man to take a laggard, last-minute interest in me, and by now I was pushing everything out into the paired first person–it was, I said, “Our night shot,” and I began including the two of us in whatever it might be doing out, the expected sprinkles and such—but he was no friendship buff, and he paid no heed to my telling him that the only dress of hers I'd ever twidged myself into even part of the way had been the simplest of them all, a large-buttoned wonder of depthless blue, and then only on the principle that one naturally fits whatever one has into whatever somebody else [169] had first, or how else would the world keep getting any taller with people? The man just went about the removal of the girl's things without having to be reminded too noticeably, I guess, of how every dick hangs by a thread. My listener, though, had by this time brought about some becoming slowings of her arm—it was an arm inclinable to langorous diagonals and magicianly swoops through the air above the tabletop—but it no longer was involving itself with her plate, so I suggested we shove off, I made payment for the food, and on our way to the car, and then in the car as I took to following her pointings, the directional tilts of her head, she said that you naturally kept putting more and more of yourself into another person, at first wondering how much she can take, how much of you is accumulable and how much she can hold, and you're letting things out, disbursing yourself, and you've soon got things set up in her, and room is being made for even more of you, and if you bring this off with enough people, even two or three, what you've got is at first a comfort, because you can pass yourself along and move a little more widely through the world and leave it to these others to man your grievances, your disappointments; and what brought this to mind, the woman said, was a term of financial hardship she had contrived for herself a few years back, an unpaid leave of absence from scrupling letter grades onto quiz papers (propped-up As, and upended Bs made to look, rather, like fannies; all As and Bs, no Cs or anything lower, the difference between an A and a B having less to do with the accuracy of whatever facts might [170] have been impounded in provided for an answer than with anything recallable about the way the enrollee ad conformed her body to the confining perpendiculars of her chair and the navel-level writing surface that projected from it, or the way there might one day have been an unignorable blush on the instep of a once-moseying foot, disburdened of its shoe, that had got itself trapped in the grillwork of that cagelike involvement, intended for books, that was welded to, or otherwise schemed into, the underworks of the chair)—this had been a duration, in short, of controlled difficulty when the misexpenditure of even a twenty-dollar bill had set her thrilling, gloating, over everything she would miss out on, and one afternoon she had made an engagement for a haircut, just a trim, and very early in the session the haircutter, a woman ill-defined in the face but otherwise full of conspicuities of emotion, set down the prevailing scissors and pressed the flat of a lukewarm hand against the woman's cheek, held it there for a good minute or longer, while the other hand eventually found its way into a drawer, a shallow treasury of slender specialty scissors, one pair of which the cutter withdrew and began routing deductively through the woman's hair, the other hand staying put on the cheek, longer and longer, and the woman went home and for afterward the bathtub was now a more likely destination than any of the upright furniture, and it got easier to fill the tub with further clarifying volumes than to clear space on the difficult heights of the sofa, and she was hardly claiming to have become a cleaner [171] person in result—she in fact would often discover, voyaging about her body, a browned, fractionary detail of a larger crepe of toilet tissue that must have got itself stuck in some assy crevice and was impossible to get plucked out of the revolving suds—she was saying only that she spent more and more of her time thus immersed, ill off in water, and the haircutter had surely had a hand in it, the woman was doing some of the cutter's life now, coming into some of its wrong, because you sometimes have to look to somebody else's life to get dimensions set back even part of the way around your own, and it should not have to be any less your own life when it comes from somebody else, and you could surely fudge a society out of anyone available person and get this person doubling for the many, so that in the little run of things perpetuable from one person to the next, every loose moment stood to become a complete, active finality. But by now this was a new day, with only an hour or so off it already, and the place the woman had made me bring us to, the man's place, with a promise that the man was elsewhere—this was on a little offshoot of a street, a stewy efficiency apartment the color had long ago gone out of; and when, once in bed, still clothed, I found among the sheets and blankets a spoiling pair of the man's underpants, one of the leg openings of which was puckered into an avid, sloppy mouth, I held myself accountable for redisposing the fabric until I got a befitting featurelessness back onto it; but all the while, I am sure I had to make myself go over again in my mind that if the body is the porter of as many organs of affec-[172]tion as there might one day turn out to be, then the idea was to let the thing carry you to where you would otherwise never have any reason to arrive, because I listened for the unmelodiof the the thede ofthe woman's zipper, and then the woman made me put myself out of my own clothes, the attritional corduroys and overshirt, and got herself up at last onto the topic not of the man whose apartment it was (because his story was scarcely the story of how the boy who decides he is half a girl no sooner starts to worry about where the other half might than he gets careless with where he rests his eyes, or what he gives even the feeblest of fingerholds to, and anything, even a crumbly triangle of pie offered on a saucer instead of on a pie plate proper, comes in easy, ready, wronging answer), but of her husband, and how, no more than a couple of months into the marriage, he had begun snugging away in his undershorts a little source of chanc, reliable frictions to nudge him onward through the workday—anything company-keeping that could be counted on not to slide out of the elasticky leg holes: a half-dollar packet of chocolate tittles, maybe, that was barely noticeable in the baggy surround of the widecut trousers so popular at the time. For by now the woman had at last brought what is usually called the other mouth to within only inches of my lips, but it is not a mouth, obviously, although I let myself go along with the goodwill behind the comparison, the way I will remain loyal to anything deliberately and faithfully misunderstood, and I fussed my tongue against the vital trifles hung inside of her, as much of the curtailed finery as I could find, [173] and gave the whole insimplicity of it a slow-circling, examinational lick, until I was taking a sudden tepid downwash on the tongue. It was a familiar, latrine in dribble that must have tasted, no doubt, like trouble just starting out.p [1] Editor's Note: Original pagination from first edition print denoted with bracketed page numbers.

This study suggests a new approach to EEG data classification by exploring the idea of using evolutionary computation to both select useful discriminative EEG features and optimise the topology of Artificial Neural Networks. An evolutionary algorithm is applied to select the most informative features from an initial set of 2550 EEG statistical features. Optimisation of a Multilayer Perceptron is performed with an evolutionary approach before classification to estimate the best hyperparameters of the network. Deep learning and tuning with Long Short-Term (...) Memory are also explored, and Adaptive Boosting of the two types of models is tested for each problem. Three experiments are provided for comparison using different classifiers: one for attention state classification, one for emotional sentiment classification, and a third experiment in which the goal is to guess the number a subject is thinking of. The obtained results show that an Adaptive Boosted LSTM can achieve an accuracy of 84.44%, 97.06%, and 9.94% on the attentional, emotional, and number datasets, respectively. An evolutionary-optimised MLP achieves results close to the Adaptive Boosted LSTM for the two first experiments and significantly higher for the number-guessing experiment with an Adaptive Boosted DEvo MLP reaching 31.35%, while being significantly quicker to train and classify. In particular, the accuracy of the nonboosted DEvo MLP was of 79.81%, 96.11%, and 27.07% in the same benchmarks. Two datasets for the experiments were gathered using a Muse EEG headband with four electrodes corresponding to TP9, AF7, AF8, and TP10 locations of the international EEG placement standard. The EEG MindBigData digits dataset was gathered from the TP9, FP1, FP2, and TP10 locations. (shrink)

With the advent of Web 2.0, numerous social software applications allow people to publish and share information on the Internet. Two of these types of applications – collaborative workspaces and social network sites – have a number of features in common, which are explored to provide a basis for comparative analysis. This basis is extended with a suitable definition of privacy, a sociological perspective and an applicable adversary model in order to facilitate an investigation of similarities and differences with (...) regard to privacy threats. Practical examples are derived from the use of Wikipedia and Facebook. Analysis suggests that a combination of technical, legal, and normative solutions should be considered to counter privacy issues. A number of potential solutions that may mitigate these issues are proposed. (shrink)

Technology used in online marketing has advanced to a state where collection, enhancement and aggregation of information are instantaneous. This proliferation of customer information focused technology brings with it a host of issues surrounding customer privacy. This article makes two key contributions to the debate concerning digital privacy. First, we use theories of justice to help understand the way consumers conceive of, and react to, privacy concerns. Specifically, it is argued that an important component of consumers' privacy concerns relates to (...) fairness judgments, which in turn comprise of the two primary components of distributive and procedural justice. Second, we make a number of prescriptions, aimed at both firms and regulators, based on the notion that consumers respond to perceived privacy violations in much the same way they would respond to an unfair exchange.

Comparative constructions form two classes, those that permit direct comparisons (comparisons of measurements as in Seymour is taller than he is wide) and those that only allow indirect comparisons (comparisons of relative positions on separate scales as in Esme is more beautiful than Einstein is intelligent). In contrast with other semantic theories, this paper proposes that the interpretation of the comparative morpheme remains the same whether it appears in sentences that compare individuals directly or indirectly. To develop a unified account, (...) I suggest that all comparisons (whether in terms of height, intelligence or beauty) involve a scale of universal degrees that are isomorphic to the rational (fractional) numbers between 0 and 1. Crucial to a unified treatment, the connection between the individuals being compared and universal degrees involves two steps. First individuals are mapped to a value on a primary scale that ranks individuals with respect to the gradable property (whether it be height, beauty or intelligence). Second, the value on the primary scale is mapped to a universal degree that encodes the value’s relative position on the primary scale. Direct comparison results if measurements such as seven feet participate in the primary scale (as in Seven feet is tall). Otherwise the result is an indirect comparison. (shrink)

There have been a number of earlier investigations, using differing methodologies, into the extent to which teachers in the secondary school interact with boys and girls and the results have suggested an imbalance in the teachers? verbal behaviour towards the genders that is quite similar to the imbalance found in teachers? behaviour in the primary school. The main aim of this study was to devise an investigation using the same methodology as that used in a recent primary school investigation (...) in order to be able to make a fair comparison between the two levels. The results showed considerable differences in the teachers? verbal behaviour towards the genders in the secondary school from that of teachers in the primary school. Where the primary school data showed teachers interacting more with the boys than the girls and the boys being less on?task than the girls, the secondary school data showed no such differences.

A heuristic comparison is made of relativistic and non-relativistic quantum theory. To this end the Segal approach is described for the non-specialist. The significance of antimatter to the local and microcausal properties of the fields is laid bare. The fundamental difference between relativistic and non-relativistic (complex) fields is traced to the existence of two kinds of complex numbers in the relativistic case. Their relation to covariant and Newton-Wigner locality is formulated.

Research on the cognitive abilities involved in decision making has shown that, under objective risk conditions (i.e., when explicit information about possible outcomes and risks is available), superior decisions are especially predicted by executive functions and exact number processing skills, also referred to as objective numeracy. So far, decision-making research has mainly focused on exact number processing skills, such as performing calculations or transformations of symbolic numbers. There is evidence that such exact numeric skills are based on approximate (...) number processing (ANP) skills, which enable quick and accurate processing of non-symbolic numbers (e.g. Chen and Li, 2014). Very few studies, however, have investigated ANP skills in the context of risky decision making and have analyzed direct associations among the aforementioned sub functions. Possible interactions between the closely related skills have not been considered. The current study (N = 128) examines interactions of ANP skills with executive functions and objective numeracy, in predicting risky choice behavior. ANP skills are represented by the accuracy in a dot-comparison task. Decision making is measured by two versions of the Game of Dice Task (GDT), which place different emphases on the reflection of potential risks. The results show two-way as well as three-way interactions between the measures of ANP skills, executive functions, and objective numeracy in predicting risky decisions in both GDT versions. The riskiest decisions were most frequently made in case of low scores in all of the three competencies, while good performance in any one of them resulted in significant reductions of disadvantageous decisions. The findings indicate that high ANP skills can positively affect choice behavior in individuals who have weaknesses in reflectively attributed skills, namely executive functions and objective numeracy. Potential compensatory effects and mechanisms of ANP in decision making are discussed. (shrink)

Resilience and digital skills could be considered necessary competencies for the individual of the twenty-first century, which the current social reality suggests. For this reason we carried out a research in the institution of higher education -IES- Corporación Escuela Tecnológica del Oriente, of Bucaramanga-Colombia, which had a dual purpose: to describe resilience and digital competence in 356 of its students and establish a comparison between the values of these two aspects and those reported in other HEIs in Mexico, using (...) a quantitative, non-experimental, cross-sectional design and descriptive scope approach, the SV-RES Resilience Scale instrument and a Questionnaire for the study of the Digital Competence of Higher Education Students.

According to a now-standard theory, ‘Juliet is the sun’ is supposed to be a ‘pregnant’ metaphor, ready at any moment to beget a sprawling heap of adorable semantic puppies. Its two parts—‘Juliet’ and ‘the sun’—ostensibly meet at a virtually endless number of points, and it’s allegedly illuminating, enjoyable, or at least interesting to sit there all day spelling them out. But what if none of that is true? What if, instead, a successful creative comparison tends to offer exactly (...) two points of contact, the first of which makes it adequate, while the second gives it power? To put it metaphorically (as is only appropriate): such an image is neither an iceberg (à la Cavell) nor a simple triangle (à la Aristotle) but a tetrahedron, a muscle, a covalent bond. And the telos of such images isn’t to transmit additional information but intensify, or disorient, or even—surprisingly—make us feel at home in this miserable world. (shrink)

In this paper two theories of defeasible reasoning, Pollock's account and my theory of ranking functions, are compared, on a strategic level, since a strictly formal comparison would have been unfeasible. A brief summary of the accounts shows their basic difference: Pollock's is a strictly computational one, whereas ranking functions provide a regulative theory. Consequently, I argue that Pollock's theory is normatively defective, unable to provide a theoretical justification for its basic inference rules and thus an independent notion of (...) admissible rules. Conversely, I explain how quite a number of achievements of Pollock's account can be adequately duplicated within ranking theory. The main purpose of the paper, though, is not to settle a dispute with formal epistemology, but rather to emphasize the importance of formal methods to the whole of epistemology. (shrink)

This chapter presents arguments for two slightly different versions of the thesis that the value of persons is incomparable. Both arguments allege an incompatibility between the demands of a certain kind of practical reasoning and the presuppositions of value comparisons. The significance of these claims is assessed in the context of the “Numbers problem”—the question of whether one morally ought to benefit one group of potential aid recipients rather than another simply because they are greater in number. It is (...) argued that many of the popular approaches to this problem—even ones that avoid the aggregation of personal value—are imperiled by the incomparability theses. -/- . (shrink)

ObjectiveThe objective of this study was to validate the computerized Symbol Digit Modalities Test in a Swiss pediatric cohort, in comparing the Swiss sample to the Canadian norms. Secondly, we evaluated sex effects, age-effects, and test–retest reliability of the c-SDMT in comparison to values obtained for the paper and pencil version of the Symbol Digit Modalities Test.MethodsThis longitudinal observational study was conducted in a single-center setting at the University Children’s Hospital of Bern. Our cohort consisted of 86 children aged (...) from 8 to 16 years. The cohort included both healthy participants and patients hospitalized for a non-neurological disease. Forty eight participants were assessed during two testing sessions with the SDMT and the c-SDMT.ResultsTest–retest reliability was high in both tests. A reliable change index was calculated for the SDMT and the c-SDMT corrected for practice effects. While a significant age effect on information processing speed was observed, no such effect was found for sex. When data on the c-SDMT performance of the Swiss cohort was compared with that from a Canadian cohort, no significant difference was found for the mean time per trial in any age group. Norm values for age groups between 8 and 16 years in the Swiss cohort were established.ConclusionNorms for the c-SDMT between the Swiss and the Canadian cohort were comparable. The c-SDMT is a valid alternative to the SDMT. It is a feasible and easy to administer bedside tool due to high reliability and the lack of motor demands. (shrink)

Seven studies explored the empirical basis for claims that infants represent cardinal values of small sets of objects. Many studies investigating numerical ability did not properly control for continuous stimulus properties such as surface area, volume, contour length, or dimensions that correlate with these properties. Experiment 1 extended the standard habituation/dishabituation paradigm to a 1 vs 2 comparison with three-dimensional objects and confirmed that when number and total front surface area are confounded, infants discriminate the arrays. Experiment 2 (...) revealed that infants dishabituated to a change in front surface area but not to a change in number when the two variables were pitted against each other. Experiments 3 through 5 revealed no sensitivity to number when front surface area was controlled, and Experiments 6 and 7 extended this pattern of findings to the Wynn (1992) transformation task. Infants’ lack of a response to number, combined with their demonstrated sensitivity to one or more dimensions of continuous extent, supports the hypothesis that the representations subserving object-based attention, rather than those subserving enumeration, underlie performance in the above tasks.

Numbers are fundamental to our understanding of, and survival in, the environment. Not surprisingly, numbers represent an important psychological dimension in triggering synaesthetic experiences, such as in digit-colour synaesthesia, or number-space synaesthesia. Another important consideration is directionality in synaesthesia, in that we might ask whether the stimulus and response in any given synaesthetic variant can also work on the opposite way. Most studies have documented the typical direction of the synaesthetic experience from the inducer to the concurrent. However, it (...) seems that some synaesthetes do show bi-directionality, that is, their concurrent might also trigger the inducer either at an implicit level, or even at the explicit level that reaches perceptual awareness. We discuss these two issues in this book chapter. We will first explore synesthesia and automaticity where numbers are concerned, followed by a discussion on synaesthesia and directionality.

This paper presents the model of ‘bounded revision’ that is based on two-dimensional revision functions taking as arguments pairs consisting of an input sentence and a reference sentence. The key idea is that the input sentence is accepted as far as (and just a little further than) the reference sentence is ‘cotenable’ with it. Bounded revision satisfies the AGM axioms as well as the Same Beliefs Condition (SBC) saying that the set of beliefs accepted after the revision does not depend (...) on the reference sentence (although the posterior belief state does depend on it). Bounded revision satisfies the Darwiche–Pearl (DP) axioms for iterated belief change. If the reference sentence is fixed to be a tautology or a contradiction, two well-known one-dimensional revision operations result. Bounded revision thus naturally fills the space between conservative revision (also known as natural revision) and moderate revision (also known as lexicographic revision). I compare this approach to the two-dimensional model of ‘revision by comparison’ investigated by Fermé and Rott (Artif Intell 157:5–47, 2004 ) that satisfies neither the SBC nor the DP axioms. I conclude that two-dimensional revision operations add substantially to the expressive power of qualitative approaches that do not make use of numbers as measures of degrees of belief. (shrink)

The purposes of this study are twofold. First, it investigates how the digital media discursively react against the use of anabolic-androgenic steroids. Second, it examines how Thailand is portrayed as a venue for steroid holiday among recreational bodybuilders from the Western countries. Adhering to the principle of theoretical triangulation, the study employs two frameworks including Reisigl and Wodak’s discursive strategies and Van Dijk’s ideological structures. The methodology undertaken is a corpus-assisted discourse analysis. The corpus contains 100 articles published on various (...) websites between the period of 2014 and 2019 with the total number of 107,116 words. Main findings indicate that, regarding the first purpose, the media portray AAS as the ‘outgroup’ by employing various negative lexical items while attempting to dilute any claimed benefits. Concerning the second purpose, Thailand is represented as a venue in which AAS are easily available coupled with corrupt dealers and lax regulations. (shrink)

Most people encounter art images as digital reproductions on a computer screen instead of as originals in a museum or gallery. With the development of digital technologies, high-resolution artworks can be accessed anywhere and anytime by a large number of viewers. Since these digital images depict the same content and are attributed to the same artist as the original, it is often implicitly assumed that their aesthetic evaluation will be similar. When it comes to the digital reproductions of art, (...) however, it is also obvious that reproductions do differ from the originals in various aspects. Besides image quality, resolution, and format, the most obvious change is in the representation of color. The effects of subjectively varying surface-level image features on art evaluation have not been clearly assessed. To address this gap, we compare the evaluation of digital reproductions of 16 expressionist and impressionist paintings manipulated to have a high color saturation vs. a saturation similar to the original. We also investigate the impact of viewing time and expertise, two other aspects that may impact the perception of art in online contexts. Moreover, we link these dimensions to a recent model of aesthetic experience [the Vienna Integrated Model of Top-Down and Bottom-Up Processes in Art Perception ]. Results suggest that color saturation does not exert a major influence on liking. Cognitive and emotional aspects, however, are affected – to different extents for experts and laypersons. For laypersons, the increase in color saturation led to more positive assessments of an artwork, whereas it resulted in increased confusion for art experts. This insight is particularly important when it comes to reproducing artworks digitally. Depending on the intended use, increasing or decreasing the color saturation of the digitally reproduced image might be most appropriate. We conclude with a discussion of these findings and address the question of why empirical aesthetics requires more precise dimensions to better understand the subtle processes that take place in the perception of today’s digitally reproduced art environment.

The study has two objectives: to introduce grip force recording as a new technique for studying embodied numerical processing; and to demonstrate how three competing accounts of numerical magnitude representation can be tested by using this new technique: the Mental Number Line, A Theory of Magnitude and Embodied Cognition account. While 26 healthy adults processed visually presented single digits in a go/no-go n-back paradigm, their passive holding forces for two small sensors were recorded in both hands. Spontaneous and unconscious (...) grip force changes related to number magnitude occurred in the left hand already 100–140 ms after stimulus presentation and continued systematically. Our results support a two-step model of number processing where an initial stage is related to the automatic activation of all stimulus properties whereas a later stage consists of deeper conscious processing of the stimulus. This interpretation generalizes previous work with linguistic stimuli and elaborates the timeline of embodied cognition. We hope that the use of grip force recording will advance the field of numerical cognition research. (shrink)

We considered the question of how corporate social responsibility differs between Canada and the U.S. Prior research has identified that national institutional differences exist between the two countries [Freeman and Hasnaoui, J Business Ethics 100:419–443, 2011], which may be associated with variations in their respective CSR practices. Matten and Moon [Acad Manag Rev 33:404–424, 2008] suggested that cross-national differences in firms’ CSR are depicted by an implicit–explicit conceptual framework: explicit CSR practices are deliberate and more strategic than implicit CSR practices. (...) We compared Canada and U.S. CSR and examined how CSR strategic alliances, CSR reporting, and CSR performance in the two countries correspond to implicit versus explicit CSR practices, which we link to stakeholder and signaling perspectives. We relied upon a new database, the Sustainalytics Global Platform, and we found a positive association exists between CSR strategic alliances and the number of years that firms have issued standalone CSR reports in both countries. Moreover, we found that CSR scores mediated this association in the U.S., as U.S. firms with high CSR scores typically engage in more CSR strategic alliances. In Canada, we did not find this mediating effect. Our findings suggest that U.S. firms engage in signaling activities that are more strategic and explicit than their Canadian counterparts. This paper closes with implications for practice and theory. (shrink)

Purpose This paper aims to explore and unravel the contents portrayed in online news discourses on massive open online courses (MOOCs). Considering sociological dimensions and journalistic strategies, this study examines how online news media reflects, shapes and informs narratives about the social acceptance and use of the MOOC model of learning. Design/methodology/approach Using the Gioia methodology as the overarching framework, this study adopted a two-staged qualitative content analysis of 1,162 online news items from the websites of the top seven online (...) English newspapers of India, published between May 2012 and September 2023. In subsequent semi-structured interviews with subject matter experts, broad themes were identified. In addition, this study integrated Van Dijk’s ideological square model with media content theories to comprehensively analyze the intricate complexities in media depictions of MOOCs. Findings While manifest content analysis revealed the emergence of 25 categories, latent content analysis unveiled six broad themes: “announcements, user stages, characteristics, benefits, changing facets, and educational inequalities,” which are associated with the MOOC model. Application of Van Dijk’s model evidenced the usage of a positive self-representation strategy by Indian online news media until mid-2020. The application of media content theories underscored the predominant usage of reframing as a journalistic strategy to maintain reader interest in MOOC-related content in online news items, emphasizing the dynamic nature of media portrayals of social phenomena such as MOOCs. Practical implications The depth of MOOC-related coverage and the increasing number of news articles discussing MOOCs in Indian online media signify a growing acceptance of this educational innovation in society. Insights from emergent themes can aid administrators and platforms to effectively design and deliver future courses. In addition, understanding these themes can guide the development of media strategies to address contextual issues such as educational inequalities arising from MOOCs. This study also focuses on the necessity of upholding journalistic ethics in content dissemination. Originality/value This study provides a comprehensive synthesis of various themes and journalistic strategies adopted by online news media over the last decade in MOOC-based narratives in India. Given the distinctive Indian context, wherein MOOCs are growing rapidly amid widening digital inequalities, this research addresses calls within information systems literature to explore this phenomenon. It pioneers the integration of communication and mass media theories to analyze the complex sociological dynamics in news discourses on MOOCs, offering a novel perspective on the intersection of media representation and educational innovation.

Number-form synesthetes consciously experience numbers in spatially-defined locations. For non-synesthete individuals, a similar association of numbers and space appears in the form of an implicit mental number line as signified by the distance effect–reaction time decreases as the numerical distance between compared numbers increases. In the current experiment, three number-form synesthetes and two different non-synesthete control groups performed a number comparison task. Synesthete participants exhibited a sizeable distance effect only when presented numbers were congruent with (...) their number-form. In contrast, the controls exhibited a distance effect regardless of congruency or presentation type. The findings suggest that: number-form synesthesia impairs the ability to represent numbers in a flexible manner according to task demands; number-form synesthesia is a genuine tangible experience, triggered involuntarily; and the classic mental number line can be more pliable than previously thought and appears to be independent of cultural-lingo direction.

The author analyses the reliability and accuracy of the results of sociological research conducted using quota sampling. The author discusses the advantages and disadvantages of using quota samples compared to random samples. The main focus is on the representativeness of the obtained data and the possibility of extrapolating them to the general population.In the problem statement, the author noted that a mechanical method of forming a random sample is most often used to study public opinion in Ukraine. The main feature (...) of this method is to ensure an equal probability of selection of each element of the general population. The author emphasizes that although this method allows for easy calculation of possible errors and analysis of collected information, it has a disadvantage in representing specific groups of the population.To address this problem, the author proposes using an equal probability method of forming quota samples, which allows selecting respondents according to their quotas in the general population, thus providing a more representative model of the studied population. However, in the scientific community, there is no consensus on the use of indicators in forming quota samples, and all existing works remain at the level of theoretical assumptions.The author attempts to empirically substantiate the effectiveness of quota samples through experimentation. The hypothesis of the experiment assumes that the results of studies conducted according to quotas can be extrapolated to the general population with high accuracy and reliability using mathematical and statistical methods. During the experiment, both quota and random samples were used to compare the results.The general population consisted of 489 musical compositions represented in different proportions to eliminate the subjective component from the experiment and provide the opportunity to clearly assess and record the parameters of the initial general population for further comparison with the results of different types of samples. The musical compositions had two parameters: the name of the performer for identification and the duration of the track for digital and statistical evaluation. The analysis was carried out using a specially developed program for statistical data analysis. The collected data allowed for the assessment of the average track duration, median, skewness, standard deviation, and other statistical indicators.The results of the experiment showed that the quota sample provides more accurate results when the quotas are followed during the selection of elements of the general population. The sample obtained by random selection without adhering to quotas showed greater variability in indicators such as mean, median, skewness, and standard deviation relative to the general population. Thus, it was concluded that quota samples have advantages in sociological research, especially when specific groups of the population need to be considered.The author emphasizes the need for further research and improvement of quota sampling methods to enhance the accuracy and reliability of sociological studies, which are important for examining particular social issues.

The so-called Ricardian trade model of contemporary economic textbooks is not a rational reconstruction of Ricardo's famous numerical example in chapter seven of the Principles. It differs from the latter in terms of the definition of the four numbers, relevant cost comparison, rule for specialisation, assumptions and theoretical implications. Thus, the widespread critique regarding the unrealistic assumptions of the textbook trade model does not apply to Ricardo's original proof of comparative advantage.

Quantum physics is a linear theory, so it is somewhat puzzling that it can underlie very complex systems such as digital computers and life. This paper investigates how this is possible. Physically, such complex systems are necessarily modular hierarchical structures, with a number of key features. Firstly, they cannot be described by a single wave function: only local wave functions can exist, rather than a single wave function for a living cell, a cat, or a brain. Secondly, the quantum (...) to classical transition is characterised by contextual wave-function collapse shaped by macroscopic elements that can be described classically. Thirdly, downward causation occurs in the physical hierarchy in two key ways: by the downward influence of time dependent constraints, and by creation, modification, or deletion of lower level elements. Fourthly, there are also logical modular hierarchical structures supported by the physical ones, such as algorithms and computer programs, They are able to support arbitrary logical operations, which can influence physical outcomes as in computer aided design and 3-d printing. Finally, complex systems are necessarily open systems, with heat baths playing a key role in their dynamics and providing local arrows of time that agree with the cosmological direction of time that is established by the evolution of the universe.

A distinction often drawn is one between conservative versus revisionary conceptions of philosophical analysis with respect to commonsensical beliefs and intuitions. This paper offers a comparative investigation of two revisionary methods: Carnapian explication and ameliorative analysis as developed by S. Haslanger. It is argued that they have a number of common features, and in particular that they share a crucial political dimension: they both have the potential to serve as instrument for social reform. Indeed, they may produce improved versions (...) of key concepts of everyday life, for example those pertaining to social categories such as gender and race, which in turn may lead to social change. The systematic comparison of these two frameworks offered here, where similarities as well as differences are discussed, is likely to provide useful guidance to practitioners of both approaches, as it will highlight important aspects of each of them that tend to remain implicit and under-theorized in existing applications of these methodologies to specific questions.

The Sparse, Distributed Memory (SDM) model (Kanerva, 1984) is compared to Hopfield-type, neural-network models. A mathematical framework for comparing the two models is developed, and the capacity of each model is investigated. The capacity of the SDM can be increased independent of the dimension of the stored vectors, whereas the Hopfield capacity is limited to a fraction of this dimension. The stored information is proportional to the number of connections, and it is shown that this proportionality constant is the (...) same for the SDM, the Hopfield model, and higher-order models. The models are also compared in their ability to store and recall temporal sequences of patterns. The SDM also includes time delays so that contextual information can be used to recover sequences. A generalization of the SDM allows storage of correlated patterns. (shrink)

The study's purpose was to estimate the variety of foods consumed within standard and ethnic food categories by three groups of women between 18 and 35 years of age. Foreign-born Chinese women [N = 21], Chinese-American women [N = 20] and white American women [N = 23] kept 4-day food records, after instruction. Analysis of variance showed that the mean number of different foods consumed by the foreign-born Chinese was significantly [p < 0.05] lower than those eaten by the (...) other two groups for breads/cereals, dairy products, ethnic foods, fats, meats, sweets/sugars, and vegetable categories. White American women consumed significantly more dairy products and legumes/nuts than either of the groups of Chinese women. Diets of the Chinese-American women were more nutrient dense than those of the women in the other groups, containing significantly more energy, riboflavin, iron, folacin, and calcium than those of the foreign-born Chinese women. The percentage of kilocalories derived from fat [33–34%] did not differ among groups. 95% of foreign-born and 85% of Chinese-American women affirmed their ethnic identification by consuming foods belonging to Chinese cuisine; whereas, the percentage [30%] of white American women selecting Chinese food was significantly lower. Mexican and Italian foods were selected by significantly more white and Chinese-American women than by foreign-born Chinese women. Approximately 20% of both groups of Chinese women, but 49% of white American subjects, ate Japanese food. Chinese-American women retained a preference for Chinese food, similar to that of the foreign-born Chinese women. However, the Chinese-American women consumed cheeses, legumes, raw vegetables in salads, and foods from Italian and Mexican cuisines, indicating their acceptance of foods commonly consumed by white American women. Dietary acculturation among the Chinese-American women improved their diets over those of the foreign-born Chinese women and these results support the theory that consumption of a greater variety of foods increases nutrient density of diets.

BackgroundMental illness among Malaysian children is gradually reaching a fundamentally alarming point as it persistently shows increasing trend. The existing literature on the etiologies of children’s mental illness, highlights the most common cause to be ineffective or impaired parenting. Thus, efforts to combat mental illness in children should focus on improving the quality of parenting. Documented interventional studies focusing on this issue, particularly in Malaysia, are scarce and commonly report poor treatment outcomes stemming from inconvenient face-to-face instructions. Consequently, proposing an (...) accessible online and digital-assisted parenting program is expected to reach a larger number of parents, as it can overcome substantial barriers. Hence, this study aims to develop a universal digital-assisted preventive parenting intervention called DaPI, that aims to enhance mental health of children in Malaysia.MethodsA total of 200 parents of children aged 10–14 years will be recruited and randomized into two groups either intervention or waitlist-control based on a 1:1 ratio for a duration of 8 weeks. Those in the intervention group will receive eight sessions of the DaPI program that focus mainly on parenting and children’s mental health. The primary outcome of this study will essentially focus on the changes in parent-reported parenting behavior and parental self-efficacy. The secondary outcome will be changes in children’s mental health. Assessments will be arranged pre- and post-intervention as well as at the 1-month follow-up. Analyses will be conducted using a paired t-test and multivariate analysis of covariance.DiscussionThe expected outcome will be the establishment of DaPI in promoting children’s mental health by targeting changes in parenting behavior and parental self-efficacy in Malaysia. Findings from this study will be beneficial for policymakers to invest in parenting programs that could provide support to parents in enhancing their child’s overall development.Clinical trial registration[www.irct.ir], identifier [IRCT20211129053207N1].

Electricity is an indicator that shows the progress of a civilization; it is a product that has greatly changed the way we think about the world. Electricity price forecasting became a fundamental task in all countries due to the deregulation of the electricity market in the 1990s. This work examines the effectiveness of using multiple variables for price prediction given the large number of factors that could influence the price of the electricity market. The tests were carried out over (...) four periods using data from Spain and deep learning models. Two different attribute selection methods based on Pearson’s correlation coefficient have been used to improve the efficiency of the training process. The variables used as input to the different prediction models were chosen, considering those most commonly used previously in the literature. This study attempts to test whether using time series lags improves the non-use of lags. The results obtained have shown that lags improve the results compared to a previous work in which no lags were used. (shrink)

This paper reflects on two ideas addressed in Benoît Vermander’s essay “Edit by Number.” First, how can we apply “coherence in structure” to the historical development of textual production and edition in ancient China? And second, what concept of number underlies the considerations in the Huáinán Zǐ 淮南子? To answer the first question, this article compares the different compositional patterns of texts that, as with the Lǎo Zǐ 老子and the Yì Jīng 易經, are available to us in different (...) versions. The result of the comparison shows that the differences seem to outweigh the coherent patterns, so we must assume that some texts have undergone very large changes historically. Regarding the concept of number, different views on number are highlighted in texts of the Warring States Period and the Hàn 漢 dynasty, which shows that the Huáinán Zǐ contains a very specific concept of number and its own theory of the One.

Following the outbreak of what would become the COVID-19 pandemic, social distancing measures were quickly introduced across East Asia—including drastic shelter-in-place orders in some cities—drawing on experience with the outbreak of severe acute respiratory syndrome almost two decades ago. “Smart City” technologies and other digital tools were quickly deployed for infection control purposes, ranging from conventional thermal scanning cameras to digital tracing in the surveillance of at-risk individuals. Chatbots endowed with artificial intelligence have also been deployed to shift part of (...) healthcare provision away from hospitals and to support a number of programmes for self-management of chronic disease in the community. With the closure of schools and adults working from home, digital technologies have also sustained many aspects of both professional and social life at a pace and scale not considered to be practicable before the outbreak. This paper considers how these new experiences with digital technologies in public health surveillance are spurring digitalization in East Asian societies beyond the conventional public health context. It also considers some of the concerns and challenges that are likely to arise with rapid digitalization, particularly in healthcare. (shrink)

Purpose The digital divide has persisted in California and the USA as a whole at approximately the same level for the past decade. This is despite multiple programs being created and billions of dollars being spent to close it. This paper examines why the efforts to date have been ineffective and to offers policy alternatives that might be more successful. Design/methodology/approach Using data from three, variable constrained projects in California, this paper examines the effectiveness of information-based outreach efforts at closing (...) the digital divide. The projects tested various outreach and enrollment methods to see which, if any, could increase broadband adoption in low-income households. Findings This project found that providing low-income households’ information about low-cost broadband offerings was ineffective at closing the digital divide. The findings in this paper were similar to those of two other works that examined the federal Broadband Technology Opportunities Program grants under the American Recovery and Reinvestment Act. Practical implications The findings of this paper along with the works cited that evaluated the BTOP program should be enough to change public policy. For the past ten years, efforts to close the digital divide have focused on providing information to low-income households. However, two independent surveys show broadband adoption has remained virtually flat during that period. Social implications The digital divide brings concomitant economic and education harms and challenges that plague those unable to access information, services, educational and employment opportunities with the same ease, speed and sufficiency as their connected peers and neighbors. Those harms exacerbate the already existing education and income divides. This paper shows that without a change in strategy, those harms will persist. Originality/value This paper breaks new ground and addresses one of the weaknesses identified in existing research. To the best of author’s knowledge, this is the first paper of its type to use programs designed to generate data that can be empirically evaluated for effectiveness. Prior studies attempted to assess program effectiveness by using data generated from fully implemented government programs. However, those programs contained a vast number of unidentified variables and insufficient data collection. They were not designed to facilitate academic evaluation, and as such made a true effectiveness evaluation challenging. (shrink)
