Background Research on the impact of ethics reflection groups (ERG) (also called moral case deliberations (MCD)) is complex and scarce. Within a larger study, two years of ERG sessions have been used as an intervention to stimulate ethical reflection about the use of coercive measures. We studied changes in: employees’ attitudes regarding the use of coercion, team competence, user involvement, team cooperation and the handling of disagreement in teams. Methods We used panel data in a longitudinal design study to measure (...) variation in survey scores from multidisciplinary employees from seven departments within three Norwegian mental health care institutions at three time points (T0–T1–T2). Mixed models were used to account for dependence of data in persons who participated more than once. Results In total, 1068 surveys (from 817 employees who did and did not participate in ERG) were included in the analyses. Of these, 7.6% (N = 62) responded at three points in time, 15.5% (N = 127) at two points, and 76.8% (N = 628) once. On average, over time, respondents who participated in ERG viewed coercion more strongly as offending (p < 0.05). Those who presented a case in the ERG sessions showed lower scores on User Involvement (p < 0.001), Team Cooperation (p < 0.01) and Constructive Disagreement (p < 0.01). We observed significant differences in outcomes between individuals from different departments, as well as between different professions. Initial significant changes due to frequency of participation in ERG and case presentation in ERG did not remain statistically significant after adjustment for Departments and Professions. Differences were generally small in absolute terms, possibly due to the low amount of longitudinal data. Conclusions This study measured specific intervention-related outcome parameters for describing the impact of clinical ethics support (CES). Structural implementation of ERGs or MCDs seems to contribute to employees reporting a more critical attitude towards coercion. Ethics support is a complex intervention and studying changes over time is complex in itself. Several recommendations for strengthening the outcomes of future CES evaluation studies are discussed. CES evaluation studies are important, since—despite the intrinsic value of participating in ERG or MCD—CES inherently aims, and should aim, at improving clinical practices. (shrink)

The interventionist account provides us with several notions permitting the qualification of causal relationships. In recent years, there has been a push toward formalizing these notions using information theory. In this paper, I discuss one of them, namely causal specificity. The notion of causal specificity is ambiguous as it can refer to at least two different concepts. After having presented these, I show that current attempts to formalize causal specificity in information theoretic terms have mostly focused on one of these (...) two concepts. I then propose and apply a new information-theoretic measure which captures the other concept. (shrink)

In many applications of information theory, information measures the reduction of uncertainty that results from the knowledge that an event has occurred. Even so, an item of information learned need not be the occurrence of an event but, rather, the change in probability distribution associated with an ensemble of events. This paper examines the basic account of information, which focuses on events, and reviews how it may be naturally generalized to probability distributions/measures. The resulting information measure is special case of (...) the Rényi information divergence (also known as the Rényi entropy). This information measure, herein dubbed the variational information, meaningfully assigns a numerical bit-value to arbitrary state transitions of physical systems. The information topology of these state transitions is characterized canonically by a right and left continuity spectrum defined in terms of the Kantorovich- Wasserstein metric. These continuity spectra provide a theoretical framework for characterizing the informational continuity of evolving systems and for rigorously assessing the degree to which such systems exhibit, or fail to exhibit, continuous change.

Ever wonder if it is possible to construct a numeric scale for environmental variables, like one does for the temperature? This paper is an attempt to construct one. There are two main parts: section “Statistical Analysis of Variations” presents a general statistical strategy for environmental factor selection. Section “Nonlinear Analytical Geometric Model of Variations” develops an analytical geometric representation of system variations in response to environmental changes. The model is used to quantify the effects of environmental interactions. The paper treats (...) only one-dimensional case, however, the derivation of the case of multiple independent factors follows immediately. The general method developed in this paper may prove applicable to many different fields, such as extensions beyond classical physics, economics, and other sciences. Section “Conclusion” provides an illustration of applications, examples and implications of the results. (shrink)

In 2011, Hibbard suggested an intelligence measure for agents who compete in an adversarial sequence prediction game. We argue that Hibbard’s idea should actually be considered as two separate ideas: first, that the intelligence of such agents can be measured based on the growth rates of the runtimes of the competitors that they defeat; and second, one specific (somewhat arbitrary) method for measuring said growth rates. Whereas Hibbard’s intelligence measure is based on the latter growth-rate-measuring method, we survey (...) other methods for measuring function growth rates, and exhibit the resulting Hibbard-like intelligence measures and taxonomies. Of particular interest, we obtain intelligence taxonomies based on Big-O and Big-Theta notation systems, which taxonomies are novel in that they challenge conventional notions of what an intelligence measure should look like. We discuss how intelligence measurement of sequence predictors can indirectly serve as intelligence measurement for agents with Artificial General Intelligence (AGIs). (shrink)

It is illegitimate to read any ontology about "race" off of biological theory or data. Indeed, the technical meaning of "genetic variation" is fluid, and there is no single theoretical agreed-upon criterion for defining and distinguishing populations (or groups or clusters) given a particular set of genetic variation data. Thus, by analyzing three formal senses of "genetic variation"—diversity, differentiation, and heterozygosity—we argue that the use of biological theory for making epistemic claims about "race" can only seem plausible (...) when it relies on the user’s own assumptions about race; the move from biological measures to claims about “race” inevitably amounts to a pernicious reification. We also excavate assumptions in the history of the technical discourse over the concept of "race" (e.g., Livingstone's and Dobzhansky's 1962 exchange, Edwards' 2003 response to Lewontin 1972, as well as contemporary discussions of cladistic "race", and "races" as clusters). We show that claims about the existence (or non-existence) of "race" are underdetermined by biological facts, methods, and theories. Biological theory does not force the concept of "race" upon us; our social discourse, social ontology, and social expectations do. We become prisoners of our abstractions at our own hands, and at our own expense. (shrink)

The purpose of this study is to propose new similarity measures namely rough variational coefficient similarity measure under the rough neutrosophic environment. The weighted rough variational coefficient similarity measure has been also defined. The weighted rough variational coefficient similarity measures between the rough ideal alternative and each alternative are xxxxx calculated to find the best alternative. The ranking order of all the alternatives can be determined by using the numerical values of similarity measures. Finally, an illustrative example has been provided (...) to show the effectiveness and validity of the proposed approach. Comparisons of decision results of existing rough similarity measures have been provided. (shrink)

We prove the iteration lemmata, which are the key lemmata to show that extensions by Pmax variations satisfy absoluteness for Π2-statements in the structure 〈H , ∈, NSω 1, R 〉 for some set R of reals in L , for the following statements: The cofinality of the null ideal is ℵ1. There exists a good basis of the strong measure zero ideal.

The context of a linguisticexpression is defined as everything outside theexpression itself that is necessary forunambiguous interpretation of the expression.As meaning can be conveyed either by theimplicit, shared context or by the explicitform of the expression, the degree ofcontext-dependence or ``contextuality'' ofcommunication will vary, depending on thesituation and preferences of the languageproducer. An empirical measure of thisvariation is proposed, the ``formality'' or``F-score'', based on the frequencies ofdifferent word classes. Nouns, adjectives,articles and prepositions are more frequent inlow-context or ``formal'' types of (...) expression;pronouns, adverbs, verbs and interjections aremore frequent in high-context styles. Thismeasure adequately distinguishes differentgenres of language production using data forDutch, French, Italian, and English. Factoranalyses applied to data in 7 differentlanguages produce a similar factor as the mostimportant one. Both the data and thetheoretical model suggest that contextualitydecreases when unambiguous understandingbecomes more important or more difficult toachieve, when the separation in space, time orbackground between the interlocutors increases,and when the speaker is male, introvertedand/or academically educated.

The article deals with the problem of the dispersion of ordinal variables. At first, it specifies the very concept of dispersion for this type of scale. Then some of the most known measures that fit to the concept of ordinal variation are recalled. They are constructed with two different types of statistical models: using loss functions and using distance functions. Finally, a new approach, which is the use of an axiomatic method for the construction of a dispersion measure, is (...) proposed. Some relations and comparisons between different measures and between different approaches are shown. (shrink)

There is a growing appreciation of the extent of transcriptome variation across individual cells of the same cell type. While expression variation may be a byproduct of, for example, dynamic or homeostatic processes, here we consider whether single‐cell molecular variation per se might be crucial for population‐level function. Under this hypothesis, molecular variation indicates a diversity of hidden functional capacities within an ensemble of “identical” cells, and this functional diversity facilitates collective behavior that would be inaccessible (...) to a homogenous population. In reviewing this topic, we explore possible functions that might be carried by a heterogeneous ensemble of cells; however, this question has proven difficult to test, both because methods to manipulate molecular variation are limited and because it is complicated to define, and measure, population‐level function. We consider several possible methods to further pursue the hypothesis that “variation is function” through the use of comparative analysis and novel experimental techniques. (shrink)

Measures of student ethical sensitivity and their increases help to answer questions such as whether accounting ethics should be taught at all. We investigate different sensitivity measures and alternatives to the well-established Defining Issues Test (DIT-2, Rest, J. R. et al. [1999, Postconventional Moral Thinking: A Neo-Kohlbergian Approach (Lawrence Erlbaum Associates, Mahwah, NJ]), frequently used to measure the effects of undergraduate accounting ethics education. Because the DIT measures cognitive development, which increases with age, the DIT scores for younger accounting students (...) are typically lower, have limited range, and are not likely to vary sufficiently with corresponding choices in ethical dilemmas. Since the DIT measures only the moral judgment component of ethical decision-making, we consider the multidimensional ethical scale (MES) to allow respondents to provide explanations for their moral and other judgments. The MES has been used to measure attitudes related to justice, utility, contractualism, egoism, and relativism. Unfortunately, the MES is not comparable in one-dimension to the DIT, and unlike the DIT, the MES has no theoretical or objective base. Therefore, we construct a comparable one-dimensional relative measure, a Composite MES Score, obtained from previous research on practicing accountants. We compare the reliability of this measure to the DIT in explaining the ethical choices of 54 specially chosen, somewhat homogeneous students, whose ages range from 18 to 19, and who are taking a second semester freshman accounting course at a private, religion-affiliated university. These particular students are relatively untrained in the formal use of questionable accounting choices. These students are less likely to recognize the dilemmas of the MES and are also less likely to demonstrate sufficient variation in their DIT scores, traditionally low for freshmen students. As freshmen, they are recent graduates of high school and more likely guided by other ethical influences including friends, family, or contractual obligations (some of the MES constructs) rather than higher cognitive development. This study confirms suspicions. We find the DIT scores do not vary sufficiently to explain the moral reasoning of freshmen. For eight dilemmas and 24 choices we find the DIT score correlates with only three choices, whereas the MES regression models have at least one significant construct for 23 out of 24 ethical choices. The Composite MES Score (a relative measure) also explains 23 out of 24 choices and is statistically related to the DIT in only one of the choices. Unlike the DIT, the Composite MES permits pretest and retesting with different dilemmas to evaluate changes in ethical sensitivity. These results argue for relative rather than absolute measures of sensitivity and guides beyond cognitive development (the DIT-score) to explain undergraduate student sensitivity. (shrink)

This study examined variations in well-being as a function of the interaction between paranormal belief and psychopathology-related constructs. A United Kingdom-based, general sample of 4,402 respondents completed self-report measures assessing paranormal belief, psychopathology, and well-being. Latent profile analysis identified four distinct sub-groups: Profile 1, high Paranormal Belief and Psychopathology ; Profile 2, high Paranormal Belief and Unusual Experiences; moderate Psychopathology ; Profile 3, moderate Paranormal Belief and Psychopathology ; and Profile 4, low Paranormal Belief and Psychopathology. Multivariate analysis of variance (...) found that sub-groups with higher psychopathology scores reported lower well-being. Higher Paranormal Belief, however, was not necessarily associated with lower psychological adjustment and reduced well-being. These outcomes indicated that belief in the paranormal is not necessarily non-adaptive, and that further research is required to identify the conditions under which belief in the paranormal is maladaptive.

Various measures of inequality that have been proposed in the literature are discussed. These fall into two categories: those that measure in some objective sense—positive measures that make no explicit use of any concept of social welfare and those that measure in terms of a normative notion of social welfare and the loss incurred from unequal distribution. The characteristics of positive measures are described in respect of range, relative mean deviation, variance and the coefficient of variation, the standard deviation (...) of logarithms, the Gini coefficient, and Theil's entropy measure. Normative measures are described in terms of Dalton's measure, Atkinson's measure, axioms for additive separability, and a more general measure. (shrink)

We characterize access to empirical objects in biology from a theoretical perspective. Unlike objects in current physical theories, biological objects are the result of a history and their variations continue to generate a history. This property is the starting point of our concept of measurement. We argue that biological measurement is relative to a natural history which is shared by the different objects subjected to the measurement and is more or less constrained by biologists. We call symmetrization the theoretical and (...) often concrete operation which leads to considering biological objects as equivalent in a measurement. Last, we use our notion of measurement to analyze research strategies. Some strategies aim to bring biology closer to the epistemology of physical theories, by studying objects as similar as possible, while others build on biological diversity. (shrink)

Although gender idology is sometimes conceptualized as an identity, researchers invariably measure it with attitude scales. The author introduces a self-administered, vignette-style instrument that measures gender ideology as an identity. Using a sample of 309 married or cohabiting respondents, she demonstrates the instrument's construct validity by showing it is strongly related to measures of the evaluation and the potency of three cultural categories: a feminist, a traditionalist about women's roles, and a househusband. The author discusses the benefits of using such (...) an instrument as an alternative to attitude scales in housework studies. She also discusses how this measurement approach can be useful for measuring variation in the meaning of a marital identity and for operationalizing gender in “doing gender” investigations. (shrink)

The purpose of this study was to describe the variations in literacy achievement among native and non-native upper primary school children (grades three to six) in the Netherlands. Various measures of word decoding, reading literacy and writing skill were collected from 1091 native Dutch children, 753 children with a former Dutch colonial background and 580 children with a Mediterranean background. The results showed the non-native children to lag behind their native peers on all of the tasks, although the differences on (...) the decoding and writing tasks were fairly small. The Mediterranean children scored significantly lower than the ex-colonial children on all of the reading literacy tasks but equally high on the decoding and writing tasks. For both the native and non-native children, the same underlying factor structure was found to characterise their literacy achievement. Grade and ethnic status consistently predicted the factor scores for Word Decoding, Reading Literacy and Text Writing. In addition, socio-economic status (SES) predicted Reading Literacy and the variable sex predicted Writing Skills. (shrink)

Music exists not to be parsed, categorized, or otherwise processed, but because it provides enjoyment. Thus methodologies that concentrate on the cognitive aspects of music alone omit what is essential about this aesthetic form. This paper provides an alternative approach by proposing a measure of musical preference. Specifically, it is argued that a musical passage will be preferred to the extent that it induces synchrony in those brain structures that are responsible for processing the passage. It is first shown that (...) this conception is consistent with time-honored principle of unity in diversity. It is then argued that the synchrony measure follows from more recent results regarding a possible solution to the binding problem. The bulk of the paper, however, is concerned with verifying the measure via simulation. It is shown, in particular, that the measure applied to a network of interacting integrate and fire neurons responsible for the processing of musical stimuli produces results consistent with human musical preference. This was carried out in three areas in the context of Western classical and popular musical forms. First, the model was applied to the laws of voice leading and other principles developed in the period of common harmonic practice. Next, it was shown that the three most salient aspects of melody, the preponderance of stepwise transitions, the theme and variation nature of phrase development, and increased positive affect with exposure all follow directly from the model. Finally, it was demonstrated how a steady rhythm can increase neural synchrony and presumably positive affect. Additional simulations run on Turkish art songs show that the synchrony measure may have some applicability to non-Western musical forms. The paper concludes by arguing that the synchrony measure may, in certain cases, apply to non-musical aesthetic stimuli. (shrink)

A similarity index allowing comparisons of human populations has been defined as the common “Percentage of Isoactive Genes” or PIG, which can be calculated from any gene frequency distribution characterizing two populations. The complement to one of this value has been proved to be a distance, a measure which can be used in most techniques of cluster analysis as well as in usual representations of multivariated data (dendrograms, etc...). Furthermore, the formula can be generalized to a set of populations. From (...) a biological point of vue, PIG values are particularly meaningful, whereas other previously defined indices which tend to measure similarity or difference between populations neither have such an advantage, nor can they be expressed by a single and clear number like a percentage. Moreover,comparisons using PIG indices depend at first on the fluctuations of the most frequent genes of a distribution; on the other hand, different measures principally reflect the variations of low frequency genes, which unfortunately are nearly always poorly estimated, due to weak samples of populations.Interestingly, PIG values can be applied to any frequency distribution of any kind of objects. They can also extend to a whole set of distributions by using a mean value. When applying these measures to a series of polymorphic genetical systems such as ABO, Rhesus, MNSs, Gm and HLA, one can account for the variability or the homogeneity particular to the different human groups, with simple and objective criteria.

Measures are designed to evaluate the processes and outcomes of care associated with the delivery of clinical (and non-clinical) services. They allow for intra- and interorganizational comparison to be used continuously to improve patient health outcomes. The use of performance measures always means to abstract the complex reality (medical scenarios and procedures) in order to provide an understandable and comparable output. Measures can focus on global performance. The more detailed data are available the more specific judgements with respect to the (...) appropriateness of clinical decision-making and implementation of evidence are feasible. Externally reported measures are intended both to inform and lead to action. By providing this information, deficiencies in patient care and unnecessary variations in the care process can be uncovered. Such variations have contributed to disparities in morbidity and mortality. The developments in information technology, especially world-wide interconnectivity, standards for electronic data exchange and facilities to store and manage large amounts of data, offer the opportunity to analyse health-relevant information in order to make the delivery of healthcare services more transparent for consumers and providers. Global performance measures, such as the overall life expectancy (mortality) in a country, can give a rough orientation of how well health systems perform but they do not offer general solutions nor spe-cific insights into care processes that have to be improved. In contrast to population-based measures, case-based performance measures use a defined group of patients depending on specific patient characteristics and features of disease. By means of these measures we are able to compare the number of patients that receive a necessary medical procedure against those patients who do not. The use of case-based measures is a bottom-up approach to improve the overall performance in the long run. They are not only a tool for global orientation but can offer a straightforward link to the areas of deficient care and the underlying procedures. Performance measures are relevant to providers as well as consumers, from their own individual perspective. Cased-based measures focus on the management of individual patient. This approach to performance measurement can inform physicians in a meaningful and constructive way by monitoring their individual performance and by pointing out possible areas of improvement.

Lexical diversity, the amount of lexical variation shown by a particular concept, varies between concepts. For the conceptdrunk, for instance, nearly 3000 English expressions exist, includingblitzed, intoxicated, andhammered. For the conceptsober, however, a significantly smaller number of lexical items is available, likesoberorabstinent. While earlier variation studies have revealed that meaning-related concept characteristics correlate with the amount of lexical variation, these studies were limited in scope, being restricted to one semantic field and to one dialect area, that of (...) the Limburgish dialects of Dutch. In this paper, we investigate whether the impact of concept characteristics, viz. vagueness, lack of salience and proneness to affect, is manifest in a similar way in other dialects and other semantic fields. In particular, by extending the scope of the earlier studies to other carefully selected semantic fields, we investigate the generalizability of the impact of concept characteristics to the lexicon as a whole. The quantitative approach that we employ to measure concept characteristics and lexical diversity methodologically advances the study of linguistic variation. Theoretically, this paper contributes to the further development of Cognitive Sociolinguistics by showcasing how meaning can be a source of lexical diversity. (shrink)

Quantitative health risk assessment is a procedure for estimating the likelihood that exposure to environmental contaminants will produce certain adverse health effects, most commonly cancer. One instance of its use has been a California air toxics public “right-to-know” law. This article examines the ways in which credible health risk measurements were produced and challenged during the implementation of the California public policy. Fieldwork and documentary analysis finds that stakeholders negotiated within the formal constraints of the risk assessment procedures but still (...) expressed their competing visions for the implementation of the risk communication policy. The abstract results of the method were contextualized according to different time frames and allocations of uncertainty. Furthermore, the article demonstrates that the political process privileged consistency of measurement over accuracy, revealing political negotiations at a fundamentally technical level. The struggle and variation in interpretations can be explained best by the demand to organize the program around the discordant values of democratic accountability and technical efficiency. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Human Goodness: Pragmatic Variations on Platonic ThemesCatherine E. MorrisonHuman Goodness: Pragmatic Variations on Platonic Themes by Paul Schollmeier Cambridge: Cambridge University Press, 2006. Pp. x + 302. $80.00, cloth.This is a book about spirits—human, godly, ghostly, and alcoholic. Paul Schollmeier's Human Goodness: Pragmatic Variations on Platonic Themes explores how humble humans act morally in an absurd world. Schollmeier contends that the Socratic spirit, or daimon, of self-knowledge and (...) hypothesis testing provides the foundation for a deeply human moral philosophy. It is, in Schollmeier's elegant phrasing, daimonic rather than eudaimonic, joining Aristotle and Plato with William James, as well as contributions from the ghosts of David Hume and Immanuel Kant and a few rounds of whiskey. Spirits abound! Mixing Socratic skepticism with Jamesian empiricism, Schollmeier argues that we act best when we apply general principles held as opinion (not as certain knowledge), and tested through experience, to our particular situation. When these opinions yield fruit, we find ourselves less at the whim of our capricious surroundings; when they do not, we are obliged to recognize the provisional nature of our opinions and change them. The ends of these day-to-day activities reflect a far grander cosmological order, one we ignore to our mortal (and moral) peril. It is by engaging in this intellectual activity that we are made happy, and it is in measured pursuit of this happiness that we are virtuous. Our actions are neither absolutely true nor perfect. They are instead the best that we can do. And for a reviewer attempting to encapsulate a finely nuanced book in a small space, this is comforting advice indeed. [End Page 190]The book begins with a puzzle: The curious twin claims in Plato's Apology that, true to the Delphic oracle's proclamation, Socrates is both wise and knows nothing. The key to this apparent paradox, Schollmeier contends, is the difference between divine knowledge, "ultimate, nonhypothetical knowledge of final causes" (6), and human knowledge, which is hypothetical only. Schollmeier marshals William James to argue that as humans, we encounter objects of knowledge perceptually; even our concepts are fashioned from this meager material. Without access to divine knowledge, humans must test hypotheses and assume that they are true only provisionally.James's (and Hume's) emphasis on the passions as the foundation for action, however, gives Schollmeier pause. In order to construct a moral philosophy that avoids absolutism but remains objective, Schollmeier argues for a harmony between the intellectual and the passional that is ultimately rational, our Socratic daimon. We are neither gods nor animals. Should we surrender rationality to desire, Schollmeier warns in concert with Socrates, our already fragile perceptual knowledge will be further distorted by fickle emotion. It is precisely because our grasp on the world is so tenuous that we must pay heed to cool intellect rather than hot passion.Such skepticism of our claim to know might make one hesitant to engage in the enigmatic world—but we have no choice! In order to find our hybrid daimon, both Socratic and pragmatic, Schollmeier suggests rhetoric as the methodology best suited to serving practical knowledge because it eschews certainty in favor of probability and acknowledges that the hypotheses on which we act are tentative and revisable. To this end, Schollmeier highlights the enthymeme and argument by example as the two techniques that best suit the nature of our hypothetical knowledge, and he urges a return to philodoxy, the love of opinion.Giving up our claim to certainty need not be a dismal proposition. Having established his methodology, Schollmeier begins building a moral philosophy that embraces an ontology of change and contends that our happiness provides us with stability in the form of a rational teleology. The objects of our human happiness are fleeting and changeable, so happiness cannot be static but is, rather, an activity that is its own end, "an activity that is an intellectual inquiry" (78). Our happiness is contingent on our ability to hypothetically determine, in our particular setting, our function and then fulfill this role to the best of our abilities. Depending on the setting, it may be dancing, parenting, or simply a lively... (shrink)

Mindfulness-based interventions have proved effective in reducing various clinical symptoms and in improving general mental health and well-being. The investigation of the mechanisms of therapeutic change needs methods for assessment of mindfulness. Existing self-report measures have, however, been strongly criticized on various grounds, including distortion of the original concept, response bias, and other. We propose a psychophysiological method for the assessment of the mindfulness learned through time-limited mindfulness-based therapy by people who undergo meditation training for the first time. We use (...) the individual pre-post-therapy changes (dERPi) in the event-related brain potentials (ERPs) recorded in a passive meditation task as a measure of increased mindfulness. dERPi is computed through multivariate assessment of individual participant's ERPs. We tested the proposed method in a group of about 70 recurrently depressed participants, randomly assigned in 1.7:1 ratio to mindfulness-based cognitive therapy (MBCT) or cognitive therapy (CT). The therapy outcome was measured by the long-term change (dDS) relative to baseline in the depression symptoms (DS) assessed weekly, for 60 weeks, by an online self-report questionnaire. We found a strong, highly significant, negative correlation (r = -0.55) between dERPi (mean = 0.4) and dDS (mean = -0.7) in the MBCT group. Compared to this result, the relationship between dDS and the other (self-report) measures of mindfulness we used was substantially weaker and not significant. So was also the relationship between dERPi and dDS in the CT group. The interpretation of dERPi as a measure of increased mindfulness was further supported by positive correlations between dERPi and the other measures of mindfulness. In this study, we also replicated a previous result, namely, the increase (dLCNV) of the late contingent negative variation (LCNV) of the ERP in the MBCT group, but not in the control group (in this case, CT). We interpreted dLCNV as a measure of increased meditative concentration. The relationship between dLCNV and dDS was, however, very week, which suggests that concentration might be relatively unimportant for the therapeutic effect of mindfulness. The proposed psychophysiological method could become an important component of a "mindfulness test battery" together with self-report questionnaires and other newly developed instruments. (shrink)

'The interpretours of Plato,' wrote Sir Thomas Elyot in The Governour, 'do think that the wonderful and incomprehensible order of the celestial bodies, I mean sterres and planettes, and their motions harmonicall, gave to them that intensifly and by the deepe serche of raison beholde their coursis, in the sondrye diversities of number and tyme, a forme of imitation of a semblable motion, which they called daunsigne or sltation.' The image of the planets and stars engaged in an ordered and (...) measured dance is an ancient one. Plato articulated it in a passage in the Timaeus, where he likened the apparent motions of the planets and stars to 'choreiai'. Through the centuries the analogy has challenged Plator's interpreters to define and elaborate the image. Miller has examined a range of poetic and philosophical texts influenced by Plato cosmology, and has discovered frequent comparisons of the cosmic order to 'daunsigne.' He suggests that the vision of the cosmic dance did not develop at random in Western intellectual history but originated in a specific philosophical context and passed through stages of evolution that reflect Gnostic, Christian, Stoic, and Neoplatonic responses to Plato. He argues that the historical variations of the image were often closely related to adaption or criticisms of Plato's theories of visual perception and intellectual vision. The dance, in conjunction with images such as the Great chain of Being and the Lyre of the Heavens, became the dominant image of a peculiarly Late Antique world-view which Miller has called the 'poetic universe'; a world where metaphors, metonymies, and personifications could exist in fact as well as in word. The result of Miller's analysis is vast in scope. The nine chapters of the book each present a thesis on a particular author, but all function together like links in a chain. Miller has been described as 'an historian of visions'; the book has been likened to Auerbach's Mimesis. It is a remarkable contribution to an understanding of the complex interaction of ideas and images in time. (shrink)

Ordinary clocks do not measure time in the common and Newtonian sense, and there is a similar problem for spatial measurements due to effects of motion and gravitation. Einstein’s theories of relativity are based on the denial of the possibility of the ‘absolute’ measurements that would be required. Nevertheless, here it is shown how such measurements can be performed. For this purpose, a “light clock” (or equivalent) is linked with a “space-time odometer” that counts the zero crossings in the field (...) of the cosmic microwave background radiation. The readings of these two instruments allow to calculate the time interval and the length of their path in Euclidean space even in the presence of local variations in gravitational potential.

Arguments about the nature of teaching have depended principally on naturalistic observation and some experimental work. Additional measurement tools, and physiological variations and manipulations can provide insights on the intrinsic structure and state of the participants better than verbal descriptions alone: namely, time-series analysis, and examination of the role of hormones and neuromodulators on the behaviors of teacher and pupil.

The basic issue is the measurement of memory accuracy and how correspondence should be assessed. Problems of completeness and variations in the degree and type of inaccuracy make measurement intractably difficult. This difficulty places severe limitations on generalizing across tasks, domains, and individuals and, consequently, on theory construction.

Geographical variations are documented for a wide range of health care services. As many such variations cannot be explained by demographical or epidemiological differences, they are problematic with respect to distributive justice, quality of care, and health policy. Despite much attention, geographical variations prevail. One reason for this can be that the ethical issues of geographical variations are rarely addressed explicitly. Accordingly, the objective of this article is to analyse the ethical aspects of geographical variations in the provision of health (...) services. Applying a principlist approach the article identifies and addresses four specific ethical issues: injustice, harm, lack of beneficence, and paternalism. Then it investigates the normative leap from the description of geographical variations to the prescription of right care. Lastly, the article argues that professional approaches such as developing guidelines, checklists, appropriateness criteria, and standards of care are important measures when addressing geographical variations, but that such efforts should be accompanied and supported by ethical analysis. Hence, geographical variations are not only a healthcare provision, management, or a policy making problem, but an ethical one. Addressing the ethical issues with geographical variations is key for handling this crucial problem in the provision of health services. (shrink)

The ability to reason about how things were made is a pervasive aspect of how humans make sense of physical objects. Such reasoning is useful for a range of everyday tasks, from assembling a piece of furniture to making a sandwich and knitting a sweater. What enables people to reason in this way even about novel objects, and how do people draw upon prior experience with an object to continually refine their understanding of how to create it? To explore these (...) questions, we developed a virtual task environment to investigate how people come up with step‐by‐step procedures for recreating block towers whose composition was not readily apparent, and analyzed how the procedures they used to build them changed across repeated attempts. Specifically, participants (N = 105) viewed 2D silhouettes of eight unique block towers in a virtual environment simulating rigid‐body physics, and aimed to reconstruct each one in less than 60 s. We found that people built each tower more accurately and quickly across repeated attempts, and that this improvement reflected both group‐level convergence upon a tiny fraction of all possible viable procedures, as well as error‐dependent updating across successive attempts by the same individual. Taken together, our study presents a scalable approach to measuring consistency and variation in how people infer solutions to physical assembly problems. (shrink)

Is the term ‘racist’ being applied so widely that it is losing its moral force? Theorists and pundits from across the political spectrum think that it is. They call such a change of meaning “conceptual inflation” and argue that we should try to stop it by restricting the use of ‘racist’ or replacing ‘racist’ with new expressions. But what evidence do we have that ‘racist’ is inflated? Economists do not track currency inflation with mere vibes; they use measurements such as (...) the consumer price index. For example, using CPI, it is observable that there has been considerable US dollar inflation over the last three decades or so: $1.00 in 1989 has the purchasing power of $2.54 in 2024. If ‘racist’ has undergone a similar transformation, as critics of conceptual inflation contend, how could that be measured? Before plunging into the normative debate about whether conceptual inflation is good or bad, we should gather systematic empirical evidence about whether the purported conceptual inflation of ‘racist’ is in fact happening. That is what we do in this paper: we use an apparent time study, a technique drawn from sociolinguistics, to measure whether ‘racist’ is undergoing conceptual inflation. An apparent time study looks at the linguistic behavior of people of different ages as a way of measuring linguistic variation over time. We distinguish two processes that constitute conceptual inflation: extension expansion and intensity bleaching. Across three studies, we found some equivocal evidence that ‘racist’ has undergone extension expansion—its reference class may have slightly expanded—but no evidence that it has undergone intensity bleaching—its moral force remains the same. By comparing ‘racist’ with other terms that have plausibly undergone meaning change, like ‘queer’, we argue that claims about the conceptual inflation of ‘racist’, as they are standardly understood, are overblown.

Professor McKenzie proposes and formulates a method composed of operational procedures designed to facilitate the evaluation of economic projects and policies. This method is discussed fully, illustrated by simple examples, and compared with alternative procedures. An outline of a computer program that enables readers to undertake their own calculations is included. In order to present the approach clearly, the author provides an exposition of the fundamental ideas and the main alternative approaches to the problem. These rely on various forms of (...) index numbers and consumer surplus. However, as is well known, such measures are not capable of correctly ordering the various alternatives under consideration, except under highly unrealist assumptions. In this book the author suggests the abandonment of this traditional approach based on the concept of 'willingness-to-pay' or the conpensating variation. Instead, the measure that Samuelson has called the 'money-metric' should become the cornerstone of applied welfare economics. (shrink)

In the United States, the racial and ethnic statistics published by the National Center for Health Statistics (NCHS) assume that each member of the U.S. population has a race and ethnicity and that if a member is black or white with respect to his risk of one disease, he is the same race with respect to his risk of another. Such an assumption is mistaken. Race and ethnicity are taken by the NCHS to be an intrinsic property of members of (...) a population, when they should be taken to depend on interest. The actual or underlying race or ethnicity of members of a population depends on the risk whose variation within the population we wish to describe or explain. (shrink)

BackgroundAntipsychotic-induced weight gain is a contributing factor in the reduced life expectancy reported amongst people with psychotic disorders. CYP2D6 is a liver enzyme involved in the metabolism of many commonly used antipsychotic medications. We investigated if CYP2D6 genetic variation influenced weight or BMI among people taking antipsychotic treatment.MethodsWe conducted a systematic review and a random effects meta-analysis of publications in Pubmed, Embase, PsychInfo, and CENTRAAL that had BMI and/or weight measurements of patients on long-term antipsychotics by their CYP2D6-defined metabolic (...) groups.ResultsTwelve studies were included in the systematic review. All cohort studies suggested that the presence of reduced-function or non-functional alleles for CYP2D6 was associated with greater antipsychotic-induced weight gain, whereas most cross-sectional studies did not find any significant associations. Seventeen studies were included in the meta-analysis with clinical data of 2,041 patients, including 93 poor metabolizers, 633 intermediate metabolizers, 1,272 normal metabolizers, and 30 UMs. Overall, we did not find associations in any of the comparisons made. The estimated pooled standardized differences for the following comparisons were PM versus NM; weight = –0.07, BMI = 0.40. IM versus NM; weight = 0.09 and BMI = 0.09. UM versus EM; weight = 0.01 and BMI = –0.08.ConclusionOur systematic review of cohort studies suggested that CYP2D6 poor metabolizers have higher BMI than normal metabolizers, but the data of cross-sectional studies and the meta-analysis did not show this association. Although our review and meta-analysis constitutes one of the largest studies with comprehensively genotyped samples, the literature is still limited by small numbers of participants with genetic variants resulting in poor or UMs status. We need further studies with larger numbers of extreme metabolizers to establish its clinical utility in antipsychotic treatment. CYP2D6 is a key gene for personalized prescribing in mental health.

In response to concerns with existing procedures for measuring strategic control over implicit knowledge in artificial grammar learning , we introduce a more stringent measurement procedure. After two separate training blocks which each consisted of letter strings derived from a different grammar, participants either judged the grammaticality of novel letter strings with respect to only one of these two grammars , or had the target grammar varying randomly from trial to trial which required a higher degree of conscious flexible (...) control. Random variation in the colour and font of letters was introduced to disguise the nature of the rule and reduce explicit learning. Strategic control was observed both in the pure-block and mixed-block conditions, and even among participants who did not realise the rule was based on letter identity. This indicated detailed strategic control in the absence of explicit learning. (shrink)

Resilience is the process and outcome of healthy adaptation despite significant adversity. Proliferation of research on the resilience construct has led to scientific concerns about the operationalization and measurement of resilience for assessment science and practice. Various studies that have investigated the psychometric properties and construct validity of the Resilience Scale for Adolescents have yielded inconsistent findings, which could partly be due to variations in the methodological approaches. This study investigated the factor structure and construct validity of the READ in (...) four European regions participating in the Universal Preventive Resilience Intervention Globally Implemented in Schools to Improve and Promote Mental Health for Teenagers project. Participants included adolescents aged 10–15 years from Spain, Iceland, Italy, and Poland. The five-factor model of the READ was similar across gender and participating regions. Construct validity of the READ was supported. After establishing construct separability, incremental validity was supported. The READ is a valid and reliable measure of protective factors involved in resilience and demonstrates promise for cross-cultural applicability. Recommendations for measuring resilience and validating the READ in future investigations are provided. (shrink)

Background: Walking while performing a secondary task walking) increases cognitive workload in young adults. To date, few studies have used neurophysiological measures in combination to subjective measures to assess cognitive workload during a walking task. This combined approach can provide more insights into the amount of cognitive resources in relation with the perceived mental effort involving in a walking task.Research Question: The objective was to examine cognitive workload in young adults during walking conditions varying in complexity.Methods: Twenty-five young adults performed (...) four conditions: usual walking, simple DT walking, complex DT walking and standing while subtracting. During the walking task, mean speed, cadence, stride time, stride length, and their respective coefficient of variation were recorded. Cognitive workload will be measured through changes in oxy- and deoxy-hemoglobin during walking in the dorsolateral prefrontal cortex and perceived mental demand score from NASA-TLX questionnaire.Results: In young adults, ΔHbO2 in the DLPFC increased from usual walking to both DT walking conditions and standing while subtracting condition. ΔHbO2 did not differ between the simple and complex DT and between the complex DT and standing while subtracting condition. Perceived mental demand gradually increased with walking task complexity. As expected, all mean values of gait parameters were altered according to task complexity. CV of speed, cadence and stride time were significantly higher during DT walking conditions than during usual walking whereas CV of stride length was only higher during complex DT walking than during usual walking.Significance: Young adults had greater cognitive workload in the two DT walking conditions compared to usual walking. However, only the mental demand score from NASA-TLX questionnaire discriminated simple from complex DT walking. Subjective measure provides complementary information to objective one on changes in cognitive workload during challenging walking tasks in young adults. These results may be useful to improve our understanding of cognitive workload during walking. (shrink)

Cramer et al. present a thoughtful application of network analysis to symptoms, but certain questions remain open. These questions involve the intended causal interpretation, the critique of latent variables, individual variation in causal networks, Borsboom's idea of networks as measurement models, and how well the data support the stability of the network results.

Uchiyama et al. rightly consider how cultural variation may influence estimates of heritability by contributing to environmental sources of variation. We disagree, however, with the idea that generalisable estimates of heritability are ever a plausible aim. Heritability estimates are always context-specific, and to suggest otherwise is to misunderstand what heritability can and cannot tell us.

In this paper we describe a propagation experiment to measure the one-way velocity of electromagnetic radiation. The experiment utilizes the rotation of the earth to interchange the positions of two rubidium vapor frequency standards over12 h, thereby canceling initial clock phase differences. It is demonstrated that although the drift characteristics of modern rubidium atomic clocks may be large for long-term absolute timing requirements, the short-term random fluctuations are small. It is found that over a24-h period, the long-term drift can be (...) accurately parameterized in retrospect and removed, thereby permitting the detection of temporal variations less than1 nsec in magnitude. With coherent summing techniques this value may be significantly reduced, and it becomes realistic to consider an experiment where the clocks are separated by distances of the order of several hundreds of meters in order to detect velocities of the order of that of the solar system with respect to the center of the galaxy(≈10 5 m sec −1 ), thus ensuring that the rotational motion of the earth has a negligible effect in altering the relative inertial characteristics of the reference frames of each clock. It is demonstrated that under such conditions the measurement of the one-way speed of propagation of electromagnetic radiation is not only meaningful, but can be simply implemented with commercially available instrumentation.

The present study investigates the dynamics of emotional processing and awareness using an affective facial priming paradigm in conjunction with a multimodal assessment of awareness. Key facial primes are visually masked, and are presented for brief and extended durations. Using a preference measure, we examine whether the effects of the primes differ qualitatively . We show that: unconscious affective priming with faces emerges strongly in initial presentations and diminishes rapidly with repetition; conscious affective priming also emerges strongly in initial presentations, (...) however it persists in strength with repetition; and in contrast to other reports on the salience of negative stimuli, happy faces appear more salient than sad faces when presented outside awareness. We discuss the limits and extensions of unconscious affective priming with faces, and consider several methodological and conceptual questions concerning emotional processing out of awareness.
