The author has been involved in Christian Community Computer Centers or C4s since 1993 and has been researching the possibility of C4s' growth as part of a strategy in addressing the socio-economic situation in Africa. He asks if C4s, within the Information Communication Technology sector, can facilitate transformation in communities. The main thesis of this paper is that C4s play a significant role in community transformation as they have their greatest impact in poorer communities where more commercially orientated enterprises (...) are reluctant to invest in technological services. The author suggests that the one area that needs further attention concerns the question of making the Centers part of an intentional program of transforming communities especially supported by churches.

The development of technology is unbelievably rapid. From limited local networks to high speed Internet, from crude computing machines to powerful semi-conductors, the world had changed drastically compared to just a few decades ago. In the constantly renewing process of adapting to such an unnaturally high-entropy setting, innovations as well as entirely new concepts, were often born. In the business world, one such phenomenon was the creation of a new type of entrepreneurship. This paper proposes a new academic discipline of (...) computational entrepreneurship, which centers on: (i) an exponentially growing (and less expensive) computing power, to the extent that almost everybody in a modern society can own and use that; (ii) omnipresent high-speed Internet connectivity, wired or wireless, representing our modern day’s economic connectomics; (iii) growing concern of exploiting “serendipity” for a strategic commercial advantage; and (iv) growing capabilities of lay people in performing calculations for their informed decisions in taking fast-moving entrepreneurial opportunities. Computational entrepreneurship has slowly become a new mode of operation for business ventures and will likely bring the academic discipline of entrepreneurship back to mainstream economics.

How do our personalities and mental processes, our " states of consciousness" , derive from a gray mass of tissue with the consistency of a soft-boiled egg? How can mere molecules constitute an idea or emotion? Some of the most important questions we can ask are about our own consciousness. Our personalities, our individuality, indeed our whole reason for living, lie in the brain and in the elusive phenomenon of consciousness it generates. Thinkers in many disciplines have long struggled with (...) such questions, often in ways that have seemed incompatible, if not downright contradictory. Philosophers have meditated on the subjective experience of consciousness, with little attention to the physical realm, while scientists have sought to establish a causal relation between brain function and mind, often ignoring the qualitative aspects of experience. In Journey to the Centers of the Mind, neuroscientist Susan Greenfield offers an intriguing, unifying theory of consciousness that encompasses both phenomenological mental events and physical aspects of brain function. Using information gathered from clues in animal behavior, human brain damage, computer science, neurobiology, and philosophy, Greenfield offers a " concentric theory" of consciousness, and shows how certain events in the brain correspond to our qualitative experience of the world. Demonstrating the ways in which we can interpret the experience of consciousness in terms of interactions among neurons, she explores how much we can learn by continuing to find the links between our physical and mental inner worlds.

In a continuum of past and present, "Pittsburgh Then and Now" portrays the city through 161 pairs of matching photographs. Each archival image, culled from old books, municipal records, and library collections, was rephotographed in 1986-89 from the same camera position, forming an evocation of the past and a record of urban continuity and change. "Pittsburgh Then and Now" recalls specific locations in the city of the past and then compares them to the present, showing both how much (...) and how little Pittsburgh has changed. Most of the pairs of photographs illustrate continuity with the past, features that have remained over the decades. A steep residential street in Perry Hilltop, for example, is little changed, and a jagged hillside staircase on the South Side is still in use. Other images document urban change. Massive Duquesne Gardens, on Craig Street in Oakland, is shown alongside the University Square Apartments of the present. The old Loew's Penn Theatre on Sixth Street in 1935 is copared to its modern manifestation as Heinz hall, 1987. The pre-Renaissance cornor of Stanwyx Street and Penn Avenue is recalled before the Gateway buildings were constructed.This journey into the past shows how change and continuity have mingled in the city landscape, reveling Pittsburgh as it has evolved from architecutral styles that reflected turn-of-the-century eclecticism to the more recent styles labeled "modernist" and "postmodernist, " from horse to streetcar to automobile, and from steel mills to high-technology centers. "Pittsburgh Then and Now" is a treasury of photographic images for those who remember the old Pittsburgh, those who are curious about its past, and anyoneinterested in the evolution of a city.

As an advanced network calculation mode, cloud computing is becoming more and more popular. However, with the proliferation of large data centers hosting cloud applications, the growth of energy consumption has been explosive. Surveys show that a remarkable part of the large energy consumed in data center results from over-provisioning of the network resource to meet requests during peak demand times. In this paper, we propose a solution to this problem by constructing a dynamic energy-efficient resource management scheme. As (...) a way of saving energy as well as maintaining cloud user’s quality of experience, the scheme presents a multitier cloud architecture by configuring physical machines into two pools: a hot pool and a warm pool. Each PM is configured with a resource search engine that finds an available virtual machine for the request, and a synchronous sleep mechanism is introduced to the warm pool. To analyze the end-to-end performance of the cloud system’s service with the proposed scheme, we establish a hybrid queueing system composed of three stochastic submodels by using a matrix-geometric solution. Accordingly, the average latency of requests and the energy-saving rate of the system are derived. Through numerical results, we show the influence of the synchronous sleep mechanism on the system performance. Moreover, from the perspective of economics, we build a system cost function to study the trade-off between different performance measures. An improved Salp Swarm Algorithm is presented to minimize the system cost and optimize the sleep parameter. (shrink)

The history of computing usually focuses on achievements in Western universities and research centers and is mostly about what happened in the United States and Great Britain. However, in Eastern Europe, particularly in war-torn Poland, where there was very little state funding, many highly original hardware and software projects were initiated. The small number of publications available to us, especially those in English, led to the belief that technological progress was the result of research carried out in Western countries (...) alone. This article aims to fill this knowledge gap by focusing on the numerous research projects initiated in Polish universities and computer industries that unfortunately turned into dead ends as the result of socialist policies. These are references that cannot be ignored, not only for a historical reconstruction of the evolution of technology but also with regard to the social effects recorded in Poland immediately after the Second World War. The communist ideology, which pursued gender equality policies after the end of the war, encouraged women to pursue education, enabling the many female students enrolled in mathematics degree courses to specialize in “ Maszyny Matematyczne” (mathematical machines) and become, like men, experts in computer programming and design. As well as highlighting the role that Poland played in the nascent “computer science” and providing detailed information on what women contributed, this article will explain why the success of the Polish computer industry was limited due to the nonexistent coordination between the communist states (Comecon).

In 2014, the worldwide context is that the population is increasingly both expanding and aging in industrial countries. In contrast, the personal health levels of individuals could decrease. Although retirement homes and health-care centers assume most of the demand, they will most probably overflow in the next few years. One of the current solutions is e-Health, which involves biomedical monitoring but also home automation functions to compensate for disabilities that tend to increase with age. In this context, several domains (...) have to be merged while respecting the entire ecosystem: the users, their needs and environment, but also all the various actors/experts involved in this process. The issue, however, is that enormous effort is required to combine the multiple expert domains because these can be antinomic. Hence, this paper proposes a collaborative workflow that brings together these different actors and generates the control/command application. Applying model-driven engineering, this workflow makes a clear distinction between people’s health requirements, the home automation functions, and the user interface points of view. Thus, it allows experts in each field to adapt their system in terms of the user’s needs, disability, and health state. (shrink)

Action perception and recognition are core abilities fundamental for human social interaction. A parieto-frontal network (the mirror neuron system) matches visually presented biological motion information onto observers' motor representations. This process of matching the actions of others onto our own sensorimotor repertoire is thought to be important for action recognition, providing a non-mediated “motor perception” based on a bidirectional flow of information along the mirror parieto-frontal circuits. State-of-the-art machine learning strategies for hand action identification have shown better performances when sensorimotor (...) data, as opposed to visual information only, are available during learning. As speech is a particular type of action (with acoustic targets), it is expected to activate a mirror neuron mechanism. Indeed, in speech perception, motor centers have been shown to be causally involved in the discrimination of speech sounds. In this paper, we review recent neurophysiological and machine learning-based studies showing (a) the specific contribution of the motor system to speech perception and (b) that automatic phone recognition is significantly improved when motor data are used during training of classifiers (as opposed to learning from purely auditory data).

In recent years, due to the growing demand for computational resources, particularly in cloud computing systems, the data centers’ energy consumption is continually increasing, which directly causes price rise and reductions of resources’ productivity. Although many energy-aware approaches attempt to minimize the consumption of energy, they cannot minimize the violation of service-level agreements at the same time. In this paper, we propose a method using a granular neural network, which is used to model data processing. This method identifies the (...) physical hosts’ workloads before the overflow and can improve energy consumption while also reducing violation of service-level agreements. Unlike the other techniques that use a single criterion, namely, worked on the basis of the history of using the processor, we simultaneously use all the productivity rates criteria, that is, processor productivity rates, main memory, and bandwidth. Extensive real-world simulations using the CloudSim simulator show the high efficiency of the proposed algorithm. (shrink)

This study was conducted from May to June 2005 to describe the demographic characteristics and factors that affect the VCT acceptance as well as the HIV prevalence among youth VCT acceptors in Addis Ababa. Both quantitative and qualitative methods of data collection were employed. The quantitative data was generated from a two years (October 2002 to December 2004) VCT service utilization data obtained from four youth centers located in Addis Ababa. The data was analysed using univariate and multivariate analysis (...) and results were presented in the form of text, table and figures. The significance and level of associations between independent and dependant variables was computed using X2 tests and odds ratios with 95% confidence interval. The qualitative data was presented in a form of narrations using excerpts. During the period a total of 3220, youth age 15 - 24 years have sought VCT service from the four youth centres VCT service outlets. Higher proportions of females (60.2%) and youth in the age category of 20 – 24 years (58.0%) have accessed the service. The major reasons given for seeking VCT were found to be similar for male and female acceptors. About 71.2% said that they sought for VCT service because they wanted to know their HIV status, 9.5% reported because they were suspicious of being infected with HIV and 5.0% tested because they wanted to go aboard. The HIV prevalence rate is found to be significantly higher, (p = 0.00), among females 9.2 % than in males 1.7 %. Gender segregated multivariate analysis of risk factors indicated significant association of HIV infection with lack of formal education for both males and female: for males P= 0.045, OR = 18.3, 95% CI: 1.1 – 317.7 and for females P=0.00, OR=19.4, 95 % CI: 5.1 – 73.8. Additionally for females HIV infection is markedly associated with being widowed and commercial sex worker. The most common barrier for youth in Addis from accessing VCT were found to be: fear of being emotionally affected if found out HIV positive, stigma and discrimination, lack of money to pay for VCT service, absence of care and support services for people who are already infected. The challenges encountered by youth VCT counsellors were stress, absence of medical care for PLWHA, inadequacy of budget, lack of counsellors and supportive supervision. This study showed high burden of HIV infection among female youth and the risk factors associated with it. Formal education for both females and males is strongly recommended. Female focused HIV prevention interventions are indicated. Additional recommendations are also made in relation to barriers to access youth VCT and for the challenges encountered by youth VCT service providers. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 37.3 (2003) 99-104 [Access article in PDF] New York Art, Pittsburgh Art, Art 1 David Carrier Champney Family Professor Case Western Reserve University/Cleveland Institute of Art I. New York Art A fully developed artworld requires not only artists, but also a support system — schools to teach the artists, commercial galleries to display art, and the connected artmarket; public museums and their curators (...) to make that art available to the public; and also, last and least, artwriters to interpret and evaluate the art. This has been true for a long time in America and Europe. I speak of artwriters as "last and least" just because we are important only in some artworlds. In the seventeenth century Poussin depended upon commentary of intellectuals, but his contemporaries Rembrandt and Vermeer did not. In this country, New York is such an artworld and so, perhaps, is Los Angeles. These are the places where young artists go to establish themselves, and so they are the places where the most original new art tends to be made. Artists outside of those centers then imitate the art made there.Artworld centers tend to be large business centers because they require major museums and many collectors. Each component of this system is dependent upon the others. Unless they have collectors, artists cannot support themselves without doing other jobs; unless there are museums, there is no public space in which art can be seen. Unless there are artwriters, there is no way to articulate shared experience of this art. This artworld is a product of modernist bourgeois democracy. Premodern cultures did not have public museums. Nowadays information is disseminated quickly, but the role of centers as places where new art is made, seen, and discussed remains essential. Our novel electronic technologies have not changed this situation.A collecting culture requires not just wealth, but also a special sort of sensibility. In fact, the number of serious collectors anywhere is surprisingly small, as one can see in Los Angeles, which has a great deal of wealth, but a surprisingly thin gallery system. Like collectors, artwriters too are odd sorts of creatures. I usually identify myself as a New York-based critic, because that is where I see most of the shows I review. Artforum, the Burlington Magazine, and Tema Celeste, the journals I now work for have a real interest in exhibitions at the Carnegie and the Warhol, in Pittsburgh, but no concern with shows like this one. Partly the problem is that reviewing space is very hard to come by, but also the difficulty is that it is difficult to make sense of a review discussing artists who are known only locally. Even were I to identify [End Page 99] someone local as a wonderful original talent, it would be very difficult for readers who have never seen her art to evaluate that claim.In Pittsburgh we certainly have good artists, and there are several universities with art departments. But here, as elsewhere in the cities I know, the artmarket is focused on New York; and there is, so far as I can see, only modest critical support for artists. Major collectors here, as elsewhere in America, look to New York, which has a critical mass of galleries, museums, and critics. The Carnegie too, tends to look to New York when planning its shows. The curators travel widely, but most of the art they show, whether American or from elsewhere, is displayed in New York galleries. If one adopts this way of thinking about an artworld, then art made in Pittsburgh inevitably will be judged as "provincial." There are a few major artists, and many derivative ones; and those major ones, the innovators, are in the artworld centers.This is the model Vasari adopts, it is Clement Greenberg's model, and it is the basic model driving the present day artworld. To describe Pittsburgh artists as provincial, then, is to identify the sociological structure of this, a typical local artworld. There is a lot of adventure and intelligence in Pittsburgh art, but inevitably to the critic... (shrink)

Preoperative diagnosis of gastric cancer and primary gastric lymphoma is challenging and has important clinical significance. Inspired by the inductive reasoning learning of the human brain, transfer learning can improve diagnosis performance of target task by utilizing the knowledge learned from the other domains (source domain). However, most studies focus on single-source transfer learning and may lead to model performance degradation when a large domain shift exists between the single-source domain and target domain. By simulating the multi-modal information learning and (...) transfer mechanism of human brain, this study designed a multisource transfer learning feature extraction and classification framework, which can enhance the prediction performance of the target model by using multisource medical data (domain). First, this manuscript designs a feature extraction network that takes the maximum mean difference based on the Wasserstein distance as an adaptive measure of probability distribution and extracts the domain-specific invariant representations between source and target domain data. Then, aiming at the random generation of parameters bringing uncertainties to prediction accuracy and generalization ability of extreme learning machine network, the 1-norm regularization is used to implement sparse constraints of the output weight matrix and improve the robustness of the model. Finally, some experiments are carried out on the data of two medical centers. The experimental results show that the area under curves (AUCs) of the method are 0.958 and 0.929 in the two validation cohorts, respectively. The method in this manuscript can provide doctors with a better diagnostic reference, which has certain practical significance. (shrink)

Both the authorship and the dating of the so-called “Diktat für Schlick” (DFS), once attributed to Ludwig Wittgenstein and assigned by Georg Henrik von Wright to the Wittgenstein Nachlass as item 302, are debated topics in Wittgenstein and Vienna Circle research. Schulte (Waismann as Spokesman for Wittgenstein. In: McGuinness B (ed). Friedrich Waismann - causality and logical positivism. Vienna Circle Institute Yearbook 15. Springer, Dordrecht, pp 225–242, 2011) and Manninen (Waismann’s testimony of Wittgenstein’s fresh starts 1931–35. In: McGuinness B (ed). (...) Friedrich Waismann - causality and logical positivism. Vienna Circle Institute Yearbook 15. Springer, Dordrecht, pp 243–265, 2011) hold that DFS was authored by Friedrich Waismann rather than Wittgenstein. Applying techniques from computational stylometry to the authorship question, the paper concludes that DFS is located stylometrically in the middle between Waismann’s and Wittgenstein’s writings, but slightly closer to Wittgenstein, and so Wittgenstein authorship is hence stylometrically still not unlikely. The paper concludes by presenting a number of factors that speak in favour of the view that DFS might originally indeed have been dictated by Wittgenstein. For the computational stylometry component, the paper uses the Eder et al.’s (Stylometry with R: a package for computational text analysis. R Journal 8/1:107–121. Accessed 21 Oct 2021. https://journal.r-project.org/archive/2016/RJ-2016-007/index.html, 2016) “Stylometry with R” package; the degree of similarity and dissimilarity between documents is calculated by Burrows’ Delta measure; and the results are displayed using Hierarchical Cluster Analysis and Principal Components Analysis. For the text corpus part, the paper uses texts authored by Schlick, Waismann and Wittgenstein. For the archival research part, the paper refers to materials form the Schlick Nachlass in the North Holland Archives, the Waismann Nachlass in the Bodleian Libraries, the Rose Rand Nachlass in the Pittsburgh Archives of Scientific Philosophy, the Ludwig Wittgenstein Nachlass in the Trinity College Cambridge Wren Library, and the Cornell copy of the Ludwig Wittgenstein Nachlass. The paper is a follow-up on Oakes and Pichler (Computational stylometry of Wittgenstein’s ‘Diktat für Schlick’”. In: Hareide L, Johannson C, Oakes M (eds). The many facets of corpus linguistics in Bergen: In honour of Knut Hofland.

We argue that A. Damasio’s (1994) Somatic Marker hypothesis can explain why humans don’t generally suffer from the frame problem, arguably the greatest obstacle facing the Computational Theory of Mind. This involves showing how humans with damaged emotional centers are best understood as actually suffering from the frame problem. We are then able to show that, paradoxically, these results provide evidence for the Computational Theory of Mind, and in addition call into question the very distinction between easy and hard (...) problems in the contemporary philosophy of mind.

This article proposes a new bi-directional way of understanding the convergence of biology and computing. It argues for a reciprocal interaction in which biology and computing have shaped and are currently reshaping each other. In so doing, we qualify both the view of a natural marriage and of a digital shaping of biology, which are common in the literature written by scientists, STS, and communication scholars. The DNA database is at the center of this interaction. We argue that DNA databases (...) are spaces of convergence for computing and biology that change in form, meaning, and function from the 1960s to the 2000s. The first part of the article shows how, in the 1980s, DNA sequencing shifted from passively incorporating computers to be increasingly modeled in digital coding and decoding. Information retrieval algorithms, reciprocally, were altered according to the peculiarities of DNA in the first sequence-storage databases. The second part of the article investigates the impact of these reciprocal interactions and globalization on the organization of research centers, ways of conducting big science, and scientific values. Through convergence and new technologies such as data mining, biology and computing were transformed technologically, institutionally, and culturally into a new bio-data enterprise called genomics.

The philosophy of information (PI) is a new area of research with its own field of investigation and methodology. This article, based on the Herbert A. Simon Lecture of Computing and Philosophy I gave at Carnegie Mellon University in 2001, analyses the eighteen principal open problems in PI. Section 1 introduces the analysis by outlining Herbert Simon's approach to PI. Section 2 discusses some methodological considerations about what counts as a good philosophical problem. The discussion centers on Hilbert's famous (...) analysis of the central problems in mathematics. The rest of the article is devoted to the eighteen problems. These are organized into five sections: problems in the analysis of the concept of information, in semantics, in the study of intelligence, in the relation between information and nature, and in the investigation of values.

Research on computational models of scientific discovery investigates both the induction of descriptive laws and the construction of explanatory models. Although the work in law discovery centers on knowledge‐lean approaches to searching a problem space, research on deeper modeling tasks emphasizes the pivotal role of domain knowledge. As an example, our own research on inductive process modeling uses information about candidate processes to explain why variables change over time. However, our experience with IPM, an artificial intelligence system that implements (...) this approach, suggests that process knowledge is insufficient to avoid consideration of implausible models. To this end, the discovery system needs additional knowledge that constrains the model structures. We report on an extended system, SC‐IPM, that uses such information to reduce its search through the space of candidates and to produce models that human scientists find more plausible. We also argue that although people carry out less extensive search than SC‐IPM, they rely on the same forms of knowledge—processes and constraints—when constructing explanatory models. (shrink)

There is substantial disagreement among philosophers of embodied cognitive science about the meaning of embodiment. In what follows, I describe three different views that can be found in the current literature. I show how this debate centers around the question of whether the science of embodied cognition can retain the computer theory of mind. One view, which I will label body functionalism, takes the body to play the functional role of linking external resources for problem solving with internal biological (...) machinery. Embodiment is thus understood in terms of the role the body plays in supporting the computational circuits that realize cognition. Body enactivism argues by contrast that no computational account of cognition can account for the role of commonsense knowledge in our everyday practical engagement with the world. I will attempt a reconciliation of these seemingly opposed views. (shrink)

Beginning with his mancounters and exploring their temporality, materiality, and spatiality, the author explains in vivid detail how gaming as a gendered practice becomes possible. The author is interested in (and does really well) grounding gaming as gendered practice. Specifically, the author looks at gaming sites, humans and non-humans, infrastructures, power relations and the conditions that enables gaming a social activity. He is looking at the material conditions that make possible the phenomenological experiences and mobilities of certain kinds of subjects. (...) He connects home to gaming sites to colleges to clouds to gaming conventions and accomplishes this as a talented story-teller, which I appreciate as a scholar, reader, and teacher... Gender and the Grounds of Gaming is brilliant work, to begin with." - Ergin Bulut, author of A Precarious Game: The Illusion of Dream Jobs in the Video Game Industry Places provided for digital game play like remote gaming setups, campus computer labs, esports arenas, and convention centers, the overall cultures of video game play, spectatorship, and production are characterized by stark gender disparities. Despite new franchises, platforms, and initiatives expanding games beyond their conventional audience of young, cis-het white men, gaming still feels off limits or unsafe for many. Gender and the Grounds of Gaming explores the physical places, any physical context in which games are played or observed, where games are played and how they contribute to the persistence of gaming's problematic gender politics. Through a series of case studies that document the gender dynamics of the various sites where video games literally take and make place, author Nicholas Taylor unpacks questions about how place matters to digital play, how issues in gaming cultures and politics are perpetuated through particular arrangements of bodies, technologies, spaces, and infrastructures. In charting the connections between place, masculinities, and play, Gender and the Grounds of Gaming makes space for marginalized perspectives, practices, and populations in gaming cultures.

We've outsourced too much of our thinking. How do we get it back? At the height of the 2014 Ebola epidemic, a man who had recently returned from West Africa with a fever and severe abdominal pain entered a hospital in Dallas--and was sent home. Even after healthcare workers learned their patient had come from Liberia, ground zero of the Ebola hot zone, not one of those treating him considered the deadly virus as a possible cause of his condition. Shortly (...) after the man died, one of the nurses who had treated him sought clearance from the Centers for Disease Control to board a commercial flight. She reported a fever of 99.5 degrees, but because the protocol restricted travel at 100.4 degrees or higher, she was cleared. She was later confirmed to be infected with Ebola. A public health disaster akin to the one depicted in the movie Contagion was averted, but only by sheer luck. How could this happen? As Harvard lecturer and global trend watcher Vikram Mansharamani shows in this eye-opening and perspective-shifting book, our complex, data-flooded world has made us ever more reliant on experts, protocols, and technology. We've stopped thinking for ourselves. (Have you ever followed your GPS device to a deserted parking lot?) With stark and compelling examples drawn from business, sports, and everyday life, the author illustrates how in a very real sense we have outsourced too much of our thinking, relinquishing our autonomy. Of course, experts, protocols, and computer-based systems are essential to helping us make informed decisions. What we need is a new approach for integrating these information sources more effectively, harnessing the value they provide without undermining our own autonomy. The author provides principles and techniques for doing just that, empowering readers with a more critical and nuanced approach to making decisions. Think for Yourself is an indispensable guide for those looking to restore self-reliant thinking in a data-driven and technology-dependent yet overwhelmingly uncertain world. (shrink)

Every year thousands of computers deemed obsolete by companies upgrading to newer models are kept out of landfills by organizations like World Computer Exchange 1 which recycle them to schools in developing countries.

In the case of such an implementation in Goa, India by a WCE partner‐NGO the key to its (...) success has been collaboration between the NGO and the private sector to encourage the growth of local Linux support skills and with the government sector ‐ the Goa State Education Department ‐ to ensure the acceptance of Linux in the curriculum, and the provision of teacher training.

The proposed changes to the Common Rule, described in the recent Advanced Notice of Proposed Rulemaking, come more than 20 years after the U.S. Department of Health and Human Services adopted the Rule in 1991. Since that time, human subjects research has changed in significant ways. Not only has the volume of clinical research grown dramatically, this research is now regularly conducted at multiple collaborative sites that are often outside of the United States. Research takes place not only in academic (...) medical centers, but also at outpatient clinics, community hospitals, and other nontraditional venues. In addition, technological advances, such as sophisticated computer software programs, the Internet, social media, new research methods, and mobile applications have exponentially increased the volume of data available and the possibilities for accessing, analyzing, and sharing that data.

Phone calls are an essential communication channel in today’s contact centers, but they are more difficult to analyze than written or form-based interactions. To that end, companies have traditionally used surveys to gather feedback and gauge customer satisfaction. In this work, we study the relationship between self-reported customer satisfaction (CSAT) and automatic utterance-level indicators of emotion produced by affect recognition models, using a real dataset of contact center calls. We find (1) that positive valence is associated with higher CSAT (...) scores, while the presence of anger is associated with lower CSAT scores; (2) that automatically detected affective events and CSAT response rate are linked, with calls containing anger/positive valence exhibiting respectively a lower/higher response rate; (3) that the dynamics of detected emotions are linked with both CSAT scores and response rate, and that emotions detected at the end of the call have a greater weight in the relationship. These findings highlight a selection bias in self-reported CSAT leading respectively to an over/under-representation of positive/negative affect. (shrink)

La diffusione del libro nel Medioevo potrebbe essere riletta alla luce di una metafora attuale sebbene non scevra di aspetti dialettici: quella della “rete”. All’ubicazione spazio-temporale del libro nei monasteri medievali, contraddistinta da fisicità e permanenza, si sotituisce oggi un formato digitale e virtuale, che porta ad una sorta di decontestualizzazione e alla continuità del flusso di informazioni, contribuendo alla diffusione capillare del sapere. L’ottica di universalità e globalità accomuna tuttavia entrambe le epoche. Alcuni concetti-chiave dell’informatica potrebbero infatti declinarsi in (...) ambito medievale: Server-Client per la raccolta, la conservazione e la trasmissione delle conoscenze da parte dei monasteri, quali centri del sapere in Europa, agli uomini di cultura; Firewall, per alludere alla necessità di tutelare i manoscritti, mediante la copiatura e la diffusione dei codici; Community, ad indicare non solo la comunità religiosa o monastica in senso stretto, bensì l’apertura ad una costruzione del sapere mediante un’azione partecipativa. I problemi dell’autenticità delle fonti, dell’acriticità delle informazioni e la pratica delle citazioni trovano un precedente significativo nelle Sententiae di Pietro Lombardo: una sorta di “biblioteca virtuale” grazie alla collezione di passi dalla Sacra Scrittura e da fonti latine e greche, paragonabile a un moderno modello enciclopedico di sapere. The diffusion of the book in the Middle Ages could be critically read through a modern metaphor: the “net”. The space-temporal coordinates of the book shift from being physical and permanent in the Medieval monasteries, to being de-contextualized and continue in the flow of information of digital and virtual format. However the universal and global perspective is common to the contemporary and the Medieval periods. In fact some key-words of computer science could be applied to the Medieval context: Server-Client, for the collection, the preservation and the transmission of knowledge from monasteries, as cultural centers in Medieval Europe, to men of culture; Firewall, for the necessary protection of manuscripts, through copying and diffusing codes; Community, referred not only to the monastic and religious groups, but also to an open sharing of the building of knowledge. Problems like the authenticity of the sources, the lack of criticality in the reception of data, and the practice of quotations are well represented in Peter Lombard’s Sententiae: this work can be compared to a modern encyclopedia thanks to the collection of passages from the Holy Scripture and from Latin and Greek sources, as well as a “virtual library”.

When we were on that listserve together, I used to keep many of his posts because I thought that they were so insightful (unfortunately many were lost when a computer virus chewed up my email program). In all that time I do not recall ever (...) taking sharp exception to him. But this time it's happened. My beef centers on Mike's comments on my exchange with Scott and Branch. (shrink)

Why does performing certain tasks cause the aversive experience of mental effort and concomitant deterioration in task performance? One explanation posits a physical resource that is depleted over time. We propose an alternative explanation that centers on mental representations of the costs and benefits associated with task performance. Specifically, certain computational mechanisms, especially those associated with executive function, can be deployed for only a limited number of simultaneous tasks at any given moment. Consequently, the deployment of these computational mechanisms (...) carries an opportunity cost – that is, the next-best use to which these systems might be put. We argue that the phenomenology of effort can be understood as the felt output of these cost/benefit computations. In turn, the subjective experience of effort motivates reduced deployment of these computational mechanisms in the service of the present task. These opportunity cost representations, then, together with other cost/benefit calculations, determine effort expended and, everything else equal, result in performance reductions. In making our case for this position, we review alternative explanations for both the phenomenology of effort associated with these tasks and for performance reductions over time. Likewise, we review the broad range of relevant empirical results from across sub-disciplines, especially psychology and neuroscience. We hope that our proposal will help to build links among the diverse fields that have been addressing similar questions from different perspectives, and we emphasize ways in which alternative models might be empirically distinguished.

We offer an analysis of the disciplinary transformations underwent by mathematical or symbolic logic since its emergence in the late 19th century. Examined are its origins as a hybrid of philosophy and mathematics, the maturity and institutionalisation attained under the label �logic and foundations,� a second wave of institutionalisation in the Postwar period, and the institutional developments since 1975 in connection with computer science and with the study of language and informatics. Although some �internal history� is discussed, the main focus (...) is on the emergence, consolidation and convolutions of logic as a discipline, through various professional associations and journals, in centers such as Torino, Göttingen, Warsaw, Berkeley, Princeton, Carnegie Mellon, Stanford, and Amsterdam.

Tracing the leading role of emotions in the evolution of the mind, a philosopher and a psychologist pair up to reveal how thought and culture owe less to our faculty for reason than to our capacity to feel. Many accounts of the human mind concentrate on the brain’s computational power. Yet, in evolutionary terms, rational cognition emerged only the day before yesterday. For nearly 200 million years before humans developed a capacity to reason, the emotional centers of the brain (...) were hard at work. If we want to properly understand the evolution of the mind, we must explore this more primal capability that we share with other animals: the power to feel. Emotions saturate every thought and perception with the weight of feelings. The Emotional Mind reveals that many of the distinctive behaviors and social structures of our species are best discerned through the lens of emotions. Even the roots of so much that makes us uniquely human—art, mythology, religion—can be traced to feelings of caring, longing, fear, loneliness, awe, rage, lust, playfulness, and more. From prehistoric cave art to the songs of Hank Williams, Stephen T. Asma and Rami Gabriel explore how the evolution of the emotional mind stimulated our species’ cultural expression in all its rich variety. Bringing together insights and data from philosophy, biology, anthropology, neuroscience, and psychology, The Emotional Mind offers a new paradigm for understanding what it is that makes us so unique.

In lieu of an abstract, here is a brief excerpt of the content:Organ Transplant AllocationPat Milmoe McCarrick (bio)The introduction of the antibiotic, cyclosporin, which enhances the success rate of transplantation surgery, has resulted in the steady growth of organ transplantation since the mid-1980s. This growth increasingly focuses ethical interest on both the procurement and the allocation of human organs. Not everyone who might benefit from organ transplants can receive them since the number of patients in need of organs far exceeds (...) the number of organs available. Each year the waiting list for transplants increases by 20 percent, but the number of donated organs has remained stable for the past five years (Lawry 1994).Organ transplantation surgery performed on rock stars, sports heroes, politicians, and television celebrities brings questions about the fair allocation of scarce resources to the attention of everyone. Abigail Trafford, editor of Washington Post Health, wonders whether "new livers for hard livers" can be deserved when not enough organs are available for everyone who needs them. Writing about the dilemma of just allocation of organs, she calls famous recipients "poster patients" or "health care celebrities of medical catastrophe" (Trafford 1994). Personal responsibility—the viewpoint that "medical treatment should not be an entitlement program for profligate living"—is an emerging moral consideration according to Trafford. Deciding whose standards and values should apply to the allocation of organs raises many questions. Popular arguments for keeping the current criteria for allocation include: these patients are sick and therefore should be treated, regardless of the cause of their illness; former substance abusers should be able to benefit from their present abstention; physicians should treat anyone who is ill; and although many human illnesses may be caused by individual behavior, such behavior is not always used as a reason to deny care (Trafford 1995).Prior to 1984, when the government established regulations governing organ transplantation, organs routinely were given to the patients of the surgeons who excised them (Prottas 1994). In an effort to achieve a more equitable method of distribution, Congress passed the National Organ Transplant Act of 1984 (Pub. [End Page 365] L. No. 98-507, amended by Pub. L. No. 100607 and Pub. L. No. 101-616), which established a national Organ Procurement and Transplantation Network (OPTN) to improve the effectiveness of organ procurement, organ distribution, and transplant activities. The United Network for Organ Sharing (UNOS) received the federal government contract to be the OPTN.UNOS and its 66 regional organ procurement organizations (OPOs) around the nation have carried out the mandate since 1986. It requires hospitals that receive Medicare or Medicaid funds and perform transplants to belong to the network and to allocate organs according to network policies. UNOS maintains the national computer registry to match donor organs with individual recipients. In distributing organs, UNOS is required by law to use a fair and equitable system based on accepted medical criteria. UNOS regularly reevaluates its policies to ensure that organ donation and recipient selection meet criteria of efficiency and equity (UNOS Update 11 (8), 1995).At the end of June 1995, 278 transplant centers were in operation in the United States: almost all of them (247 centers) transplanted kidneys; 167 did hearts; 119, pancreases; 114, livers; 93, heart-lung; 88, lungs; 26, intestines; and only 19 centers performed pancreas islet cell transplants (UNOS Update 11 (8): 28, 1995). The number of patients waiting for organ transplants in July 1995 totalled 41,075: 29,274 were waiting for a kidney transplant; 4,937, liver; 3,298, heart; 1,816, lung; 1,223 kidney-pancreas; 240, pancreas; and 211, heart-lung (UNOS Update 11 (8): 40-41, 1995).OPOs are located in different geographic areas across the country, each with different organ needs, lengths of waiting lists, or with lists in areas with large older populations making it more difficult to find suitable donors. Black recipients often wait longer due to complex reasons including sensitization or rarer blood and antigen types (UNOS 11 (8): 31-32, 1995). When an organ becomes available, the OPO involved identifies a potential recipient from the UNOS list and offers it to the patient's surgeon. If no match can be made locally, the organ is next offered within a UNOS region, and finally, to... (shrink)

BackgroundPost-stroke depression is one of the most common neuropsychiatric diseases in patients with stroke, and it can increase the disability rate, mortality, and recurrence rate of stroke. Currently, many clinical studies have indicated that traditional Chinese medicine, such as acupuncture and herbs, Western medicine, rehabilitation, repeated transcranial magnetic stimulation, and other treatment methods, are effective in treating PSD. However, no study has formulated a comprehensive treatment plan that integrates TCM, Western medicine, and rehabilitation for PSD. Thus, this trial aims to (...) assess the efficacy and safety of integrative medicine for treating PSD.MethodsThis multicenter, prospective, randomized, controlled study aims to form a set of effective clinical treatment schemes that integrate TCM, Western medicine, and rehabilitation for PSD. A total of 202 participants recruited from four centers will be randomized into either the integrative medicine or standard care group. Standard care—basic treatment, general nursing care, and exercise therapy—will be provided to all participants. The integrative medicine group will also receive acupuncture, Chinese herbs, and repeated transcranial magnetic stimulation. Participants will receive acupuncture and rTMS treatments five times per week for 4 weeks and will be administered Chinese herbs, basic treatment, general nursing care, and exercise therapy for 4 weeks. The primary outcomes include the Hamilton Depression Scale, Self-Rating Depression Scale, and Activity of Daily Living Scale. And the secondary outcomes include the Montreal Cognitive Assessment Scale, the Fugl-Meyer Assessment Scale, and the Pittsburgh Sleep Quality Index. All outcome measures will be evaluated at baseline, week 4, and week 8. Safety assessments will be performed throughout the study.DiscussionThis study is expected to verify the efficacy and safety of integrative medicine for treating PSD, providing an evidence-based clinical reference for the future development of a standardized scheme.Clinical trial registrationClinicalTrials.gov, identifier: NCT05187975.

In the bitcoin whitepaper, Satoshi Nakamoto (2008: 2) defines an electronic coin as a chain of digital signatures. Many have since defined a bitcoin as a chain of digital signatures. This latter definition continues to appear in reports from central banks, advocacy centers, and governments, as well as in academic papers across the disciplines of law, economics, computer science, cryptography, management, and philosophy. Some have even used it to argue that what we now call bitcoin is not the real (...) bitcoin. The definition fails, however. This is important because the Chain Definition obscures Satoshi’s solution to a dilemma in the design of electronic cash, as well as the truth about bitcoin’s privacy and fungibility. In this article, I explain why the Chain Definition fails and what Satoshi likely endorsed instead. Along the way, I untangle some issues around bitcoin fungibility and clarify some others around the ontology of digital assets. (shrink)

The research discussed in this paper centers around the convergence of extended reality (XR) platforms, computational design, digital fabrication, and critical urban study practices. Its aim is to cultivate interdisciplinary and multiscalar approaches within these domains. The research endeavor represents a collaborative effort between two primary disciplines: critical urban studies, which prioritize socio-environmental justice, and integrated digital design to production, which emphasize the realization of volumetric or voxel-based structural systems. Moreover, the exploration encompasses augmented reality to assess its utilization (...) in both the assembly process of the structures and the integration of phygital (physical and digital) data with the physical environment. Within the context of these research scopes, this paper introduces FabriCity-XR as an interactive phygital installation. In addition to presenting an overview of the integrated research driven and performative design to production methodologies, the project showcases the practical implementation of web-based augmented reality trails, eliminating the requirement for external applications for interaction. This approach allows users to seamlessly navigate and engage with phygital content overlaid on physical objects using their personal smart devices. The result is a captivating and immersive user experience that effectively merges the physical and digital realms. (shrink)

Advanced technologies such as drones, intelligent algorithms and androids have grave implications for human existence. With the purpose of exploring their basis for doing so, the paper proposes a framework for investigating the complex relationship between such devices and human practices and language-mediated cognition. Specifically, it centers on the importance of the typically neglected intermediate layer of culture which not only drives both technophobia and philia but also, more fundamentally, connects pre-reflective experience and socio-material practices by placing advanced technologies (...) in the loop. Theoretically, the paper draws on contributions from performativist Science and Technology Studies and Radically Embodied Cognitive Science and pushes new grounds by stressing their compatibility. Yet, it also emphasizes the importance of the enlanguaged side of cognition which is a requirement for human-style socio-material practices and, hence, the emergence of cultures that fetishizes certain technologies.

Who are the major figures that have shaped philosophy of science in Britain? What impact has the subject had in Britain outside academic philosophy? How have two of the major centers of the subject - in Pittsburgh and in London - interacted over the years? I begin by looking briefly at the recent history of philosophy of science in Britain and its general impact (tying this in with its interaction with the Pittsburgh Center and Pittsburgh people. (...) It seems to me, though, that the best way to celebrate an anniversary like that of the Pittsburgh Center is by predominantly looking forward rather than back. And I concentrate in this lecture on showing how philosophy of science can have an impact on issues of current concern, in Britain and more generally. (shrink)

Although disoriented young children reorient themselves in relation to the shape of the surrounding surface layout, cognitive accounts of this ability vary. The present paper tests three theories of reorientation: a snapshot theory based on visual image-matching computations, an adaptive combination theory proposing that diverse environmental cues to orientation are weighted according to their experienced reliability, and a modular theory centering on encapsulated computations of the shape of the extended surface layout. Seven experiments test these theories by manipulating (...) four properties of objects placed within a cylindrical space: their size, motion, dimensionality, and distance from the space’s borders. Their findings support the modular theory and suggest that disoriented search behavior centers on two processes: a reorientation process based on the geometry of the 3D surface layout, and a beacon-guidance process based on the local features of objects and surface markings.

We are repeatedly told that AI will help us to solve some of the world's biggest challenges, from treating chronic diseases and reducing fatality rates in traffic accidents to fighting climate change and anticipating cybersecurity threats. However, the article contends that public discourse on AI systematically avoids considering AI’s environmental costs. Artificial Intelligence- Brevini argues- runs on technology, machines, and infrastructures that deplete scarce resources in their production, consumption, and disposal, thus increasing the amounts of energy in their use, and (...) exacerbate problems of waste and pollution. It also relies on data centers, that demands impressive amounts of energy to compute, analyse, categorize. If we want to stand a chance at tackling the Climate Emergency, then we have to stop avoiding addressing the environmental problems generated by AI. (shrink)

Education theorists have emphasized that transformative learning is not simply a matter of students gaining access to new knowledge and information, but instead centers upon personal transformation: it alters students’ perspectives, interpretations, and responses. How should learning that brings about this sort of self-transformation be understood from the perspectives of philosophy of mind and cognitive science? Jack Mezirow has described transformative learning primarily in terms of critical reflection, meta-cognitive reasoning, and the questioning of assumptions and beliefs. And within mainstream (...) philosophy of mind, there has been a long-standing assumption that cognition and thought are brain-based, computational, disembodied processes that occur separately from emotion and affect. According to this view, selftransformation might be construed as the forging of new neural connections and the development of new cognitive “programs.” However, I will argue that the literature on embodiment and enactivism that has emerged in recent years offers us a different and more productive way to conceptualize the intended effects of transformative learning. From the standpoint of enactivism, the experience of transformative learning is thoroughly bound up with the cognitive shifts that it involves, and it also involves significant changes to the neurobiological dynamics of the living body. Moreover, personal transformation is not simply something that happens to subjects, but rather a process in which they are actively and dynamically engaged. In addition, this enactivist approach emphasizes that the learning process is fully embodied and fundamentally affective. From a phenomenological perspective, personal transformation can be understood as a pronounced alteration in cognitive-affective orientation; and from a neurobiological perspective, the development of new habits of mind can be understood as the formation of highly integrated patterns of bodily engagement and response. The upshot is that it is not just subjects’ brains that are altered over the course of transformative learning, but also their overall bodily and affective attunement to their surroundings. (shrink)

In his initial dissertation the author asked the question of "naturalizibility" of self-conscience; in the following book he has already criticized "naturalism" as a defect idiom. He takes language as a tool of his critical strategy. He refers to the paradox of the anthropomorphic understanding of nature and the physiomorphic self-understanding of man. There are three main parts in the book. First, various naturalist strategies, starting with American Naturalism, are exposed. Human language has been characterized as an unconventional means of (...) description of natural and factual contents. Three areas, or "paradigms," have been found exemplary for the "naturalism at work", evolutionary theory, psychoanalysis, and cybernetics. The next part centers in two chapters on the "language dualism" where there is a concept tension caused by the spirit-body problem and the two universes of discourse, in accord with the ideals of naturalism, should not be ontologically substantiated. In accord with the fundamental theory, one can assert a mentalist or a physicalist discourse, the language of action or of occurrence, or also the intentionalist or mechanist idiom. The third main block of exposition analyses the two basic types of metaphors, namely, the anthropomorphic and the physiomorphic. Before starting his survey of five metaphor theories, Keil expressly rejects the Iconic Signification Theory. He is sure metaphors are hyper-conceptual elements of language. Two of the theories present more virtues than defects, the Theory of Interaction and the pragmatist Theory of Indirect Communication. At the end of these reflections the author confronts the metaphor of man as a machine with teleology and, on the other hand, thinks of problems linked with the human spirit as a computer metaphor. Two chapters form the finale of the book. In accord with Keil the concept of nature in the natural sciences seems to have died out resulting in "naturalism" becoming a conceptually unclear term. Another problem is causality, for the "propter hoc" is not unfolded in the world of bodies. Relations, including causal ones, are abstract entities. The notion of causality in nature cannot be counted as an intentional concept but, at the same time, causal theories of knowledge and action cannot serve to naturalize intentionality. (shrink)

In the process of communication between people, everyone will have emotions, and different emotions will have different effects on communication. With the help of external performance information accompanied by emotional expression, such as emotional speech signals or facial expressions, people can easily communicate with each other and understand each other. Emotion recognition is an important network of affective computers and research centers for signal processing, pattern detection, artificial intelligence, and human-computer interaction. Emotions convey important information in human communication and (...) communication. Since the end of the last century, people have started the research on emotion recognition, especially how to correctly judge the emotion type has invested a lot of time and energy. In this paper, multi-modal emotion recognition is introduced to recognize facial expressions and speech, and conduct research on adaptive higher education management. Language and expression are the most direct ways for people to express their emotions. After obtaining the framework of the dual-modal emotion recognition system, the BOW model is used to identify the characteristic movement of local areas or key points. The recognition rates of emotion recognition for 1,000 audios of anger, disgust, fear, happiness, sadness and surprise are: 97.3, 83.75, 64.87, 89.87, 84.12, and 86.68%, respectively. (shrink)

Increasingly, epistemologists are becoming interested in social structures and their effect on epistemic enterprises, but little attention has been paid to the proper distribution of experimental results among scientists. This paper will analyze a model first suggested by two economists, which nicely captures one type of learning situation faced by scientists. The results of a computer simulation study of this model provide two interesting conclusions. First, in some contexts, a community of scientists is, as a whole, more reliable when its (...) members are less aware of their colleagues' experimental results. Second, there is a robust tradeoff between the reliability of a community and the speed with which it reaches a correct conclusion. ‡The author would like to thank Brian Skyrms, Kyle Stanford, Jeffrey Barrett, Bruce Glymour, and the participants in the Social Dynamics Seminar at University of California–Irvine for their helpful comments.

A long‐standing debate in the study of human communication centers on the degree to which communicators tune their communicative signals (e.g., speech, gestures) for specific addressees, as opposed to taking a neutral or egocentric perspective. This tuning, called recipient design, is known to occur under special conditions (e.g., when errors in communication need to be corrected), but several researchers have argued that it is not an intrinsic feature of human communication, because that would be computationally too demanding. In this (...) study, we contribute to this debate by studying a simple communicative behavior, communicative pointing, under conditions of successful (error‐free) communication. Using an information‐theoretic measure, called legibility, we present evidence of recipient design in communicative pointing. The legibility effect is present early in the movement, suggesting that it is an intrinsic part of the communicative plan. Moreover, it is reliable only from the viewpoint of the addressee, suggesting that the motor plan is tuned to the addressee. These findings suggest that recipient design is an intrinsic feature of human communication. (shrink)
