We have conducted an experimental study of V-type electromagnetically induced transparency in sodium. Its principles are elucidated by a simple model. Measurements show decreased fluorescence and absorption depending on the detuning of the driving and probe fields, which is in agreement with the results of numerical simulation.

We provide conceptual and empirical support for the core tenet in pragmatic theory that speakers make their communicative intention about the pragmatic meaning of their utterances recognizable to hearers. First, we attribute skepticism about this tenet to conceptualizing communicative intentions as private cognitive states that hearers cannot reliably discern. We show it is more parsimonious to conceptualize communicative intention as arising from communally shared knowledge of discursive means to ends that is the basis for pragmatic reasoning about utterance meaning by (...) speaker and hearer alike. Second, we address skepticism based on experiments interpreted as finding an egocentric bias where people regard communicative intentions as more obvious to others than they are. We report two original experiments we carried out that found that participants as third party observers and as communicators routinely engaged in pragmatic reasoning about the meaning of utterances in context that took others’ perspectives into account.

Speaker intention is conceptualized as a property of utterances in context, not speakers; it is based on communally shared knowledge of discursive means to ends. The article’s main theoretical claim is that utterances, in addition to being produced with an intention about their pragmatic meaning, are also produced with an intention to bring about some post-interactional end result. Both types of intention bear on the utterance’s pragmatic meaning. Empirical aspects of the theoretical difference between these two types of speaker intention (...) are shown through analysis of naturally occurring interactions; here, the analytical focus is on the scope, interdependence, recognizability, and fulfillment of each type of intention, with special attention to the functionality of an utterance’s content, composition, and sequential placement as a means of getting a response from the interlocutor that goes along with what the speaker intends as regards the end result of the interaction.

Previous governments and other commentators have emphasized the relationship between a teacher's knowledge of the subject material being taught and the quality of learning outcomes. This has been reflected in the entry requirements to Initial Teacher Training of public examination performance in the core subjects. However, disquiet has been expressed as to the efficacy of such qualifications as indicators of knowledge and skills at the entry point. Recent changes to ITT regulations require students' actual knowledge of the content of the (...) three core subjects to be audited. This paper reports and reflects on the effects that re-examining their knowledge and skills in mathematics has had on the confidence of primary trainee teachers. It presents some key questions that must be addressed if the current audit regulations are indeed to benefit our future teachers and to enhance the learning of our pupils. (shrink)

Theories in the behavioral sciences are constrained so that stated relationships are empirically testable and explanations have predictive power. These constraints constitute the classical paradigm, and are trivial just when ?causal relationships? do not hold. It appears that such relationships do not hold for linguistic, and presumably other, behaviors, thus precluding study within the classical paradigm. This compels study of those behaviors in terms of the non?traditional approach to testability and explanation developed in Chomskyan linguistics. These constitute the grammatical paradigm. (...) The existence of two paradigms requires that any inquiry begin by determining which paradigm is appropriate. (shrink)

Recent advances have highlighted the outstanding role of the innate immune system for instructing adaptive immunity. Translating this knowledge into successful immunotherapies like vaccines, however, has proven to be a difficult task. This essay is based on the hypothesis that immune responses are tightly scaled to the infectious threat posed by a given microbial stimulus. A meticulous immunological risk‐assessment process is therefore instrumental for eliciting well‐balanced responses and maintaining immune homeostasis. The immune system makes fine distinctions, for example, between live (...) and dead bacteria, or pathogenic and non‐pathogenic microorganisms. Here, I discuss recent evidence for some of the mechanisms underlying these distinctions and speculate on strategies for therapeutically targeting the immunological risk‐assessment machinery.

This paper describes the attributes of good mathematics teachers in the UK. These are derived from the material provided by 80 schools to applicants for mathematics teaching posts in the UK. The assumption is made that schools are trying to recruit the very best teacher and hence will have listed those attributes that they believe good teachers to have. Many of the attributes sought are not specifically about the teaching of mathematics. Indeed much about competency in the teaching of mathematics (...) is assumed and not made explicit. The requirements of schools are compared and contrasted with the Standards detailed in current Initial Teacher Training requirements and the Career Entry Profile used by newly qualified teachers.

To what extent do the mother's and father's jobs and occupational sex-typing influence the status and sex-typing of their children's occupation at first entry into the labour market? Referring to a database containing 5027 respondents of two merged Dutch surveys held between 1992 and 1995, this study finds that the effect of the mother's occupational status on her daughter's is significant, but smaller than either the effect of father's status on his son's or his daughter's status. The mother's occupational sex-typing (...) is related to her daughter's occupational sex-typing. The more female sex-typed the daughter's occupation, the lower her occupational status. In the same way, the father's occupational sex-typing is related to his son's occupational sex-typing. While the extension of the classical status attainment models by the mother's occupation and occupational sex-typing leads to interesting and new coefficients, the authors conclude that the more elementary classical model is not invalidated by these new perspectives.

Patient report of functioning is one component of the neurocognitive exam following traumatic brain injury, and standardized patient-reported outcomes measures are useful to track outcomes during rehabilitation. The Traumatic Brain Injury Quality of Life measurement system is a TBI-specific extension of the PROMIS and Neuro-QoL measurement systems that includes 20 item banks across physical, emotional, social, and cognitive domains. Previous research has evaluated the responsiveness of the TBI-QOL measures in community-dwelling individuals and found clinically important change over a 6-month assessment (...) interval in a sample of individuals who were on average 5 years post-injury. In the present study, we report on the responsiveness of the TBI-QOL Cognition–General Concerns and Executive Function item bank scores and the Cognitive Health Composite scores in a recently injured sample over a 1-year study period. Data from 128 participants with complicated mild, moderate, or severe TBI within the previous 6 months were evaluated. The majority of the sample was male, white, and non-Hispanic. The participants were 18–92 years of age and were first evaluated from 0 to 5 months post-injury. Eighty participants completed the 1-year follow-up assessment. Results show acceptable standard response mean values for all measures and minimal detectable change values ranging from 8.2 to 8.8 T-score points for Cognition–General Concerns and Executive Functioning measures. Anchor rating analysis revealed that changes in scores on the Executive Function item bank and the Cognitive Health Composite were meaningfully associated with participant-reported changes in the areas of attention, multitasking, and memory. Evaluation of change score differences by a variety of clinical indicators demonstrated a small but significant difference in the three TBI-QOL change scores by TBI injury severity grouping. These results support the responsiveness of the TBI-QOL cognition measures in newly injured individuals and provides information on the minimal important differences for the TBI-QOL cognition measures, which can be used for score interpretation by clinicians and researchers seeking patient-reported outcome measures of self-reported cognitive QOL after TBI.

In this paper we present a new proposal for defining actual causation, i.e., the problem of deciding if one event caused another. We do so within the popular counterfactual tradition initiated by Lewis, which is characterised by attributing a fundamental role to counterfactual dependence. Unlike the currently prominent definitions, our approach proceeds from the ground up: we start from basic principles, and construct a definition of causation that satisfies them. We define the concepts of counterfactual dependence and production, and put (...) forward principles such that dependence is an unnecessary but sufficient condition for causation, whereas production is an insufficient but necessary condition. The resulting definition of causation is a suitable compromise between dependence and production. Every principle is introduced by means of a paradigmatic example of causation. We illustrate some of the benefits of our approach with two examples that have spelled trouble for other accounts. We make all of this formally precise using structural equations, which we extend with a timing over all events. (shrink)

This volume addresses the intriguing issue of indirect reports from an interdisciplinary perspective. The contributors include philosophers, theoretical linguists, socio-pragmaticians, and cognitive scientists. The book is divided into four sections following the provenance of the authors. Combining the voices from leading and emerging authors in the field, it offers a detailed picture of indirect reports in the world’s languages and their significance for theoretical linguistics. Building on the previous book on indirect reports in this series, this volume adds an empirical (...) and cross-linguistic approach that covers an impressive range of languages, such as Cantonese, Japanese, Hebrew, Persian, Dutch, Spanish, Catalan, Armenian, Italian, English, Hungarian, German, Rumanian, and Basque.

This paper reconstructs the origins of Gettier-style epistemology, highlighting the philosophical and methodological debates that led to its development in the 1960s. Though present-day epistemologists assume that the search for necessary and sufficient conditions for knowledge began with Gettier’s 1963 argument against the JTB-definition, I show that this research program can be traced back to British discussions about knowledge and analysis in the 1940s and 1950s. I discuss work of, among others, Bertrand Russell, G. E. Moore, A. J. Ayer, Norman (...) Malcom, and A. D. Woozley, showing how exchanges between different schools of analytic philosophy gave rise to new ideas about the nature of knowledge and analysis. Finally, I turn to Gettier's intellectual development and argue that his paper was influenced by some of these debates, suggesting that even his interpretation of Plato’s definition of knowledge can be traced back to discussions in this period.

Andreas & Günther have recently proposed a difference-making definition of actual causation. In this paper I show that there exist conclusive counterexamples to their definition, by which I mean examples that are unacceptable to everyone, including AG. Concretely, I show that their definition allows c to cause e even when c is not a causal ancestor of e. I then proceed to identify their non-standard definition of causal models as the source of the problem, and argue that there is no (...) viable strategy open to AG to fixing it. I conclude that their definition of causation is damaged beyond repair. (shrink)

Planning problems arise in law when an individual (or corporation)wants to perform a sequence of actions that raises legal issues. Manylawyers make their living planning transactions, and a system thathelped them to solve these problems would be in demand.The designer of such a system in a common-law domain must addressseveral difficult issues, including the open-textured nature of legal rules,the relationship between legal rules and cases, the adversarial nature ofthe domain, and the role of argument. In addition, the system's design isconstrained (...) by the fact that the intended users are lawyers, and its operation and output must be convenient for lawyers to use.In this article, I describe a system called CHIRON that I have developed to explore solutions to these issues. This system develops simple plans from representations of statutes and cases in the domain of United States personal income tax planning. (shrink)

Welfare science has built its foundations on veterinary medicine and thus measures of health. Since bottlenose dolphins (Tursiops truncatus) tend to mask symptoms of poor health, management in captivity would benefit from advanced understanding on the links between health and behavioural parameters, and few studies exist on the topic. In this study, four representative behavioural and health measures were chosen: health status (as qualified by veterinarians), percentage of daily food eaten, occurrences of new rake marks (proxy measure of social activity), (...) and willingness to participate (WtP) in Positive Reinforcement Training sessions as qualitatively measured by their caretakers. These data were collected multiple times a day, every day over the course of a year from a multi-facility, large sample size (ndolphins= 51), allowing powerful analyses of the relationships between measures. First, it was found that dolphins with a higher WtP score also had a significantly better health status, ate a higher percentage of their daily food, and a lower occurrence of new rake marks. In addition, the WtP score was significantly lower up to 3 days before the weekly veterinary diagnosis of a decrease in health state; the percentage of daily food eaten and new rake mark measures did not show any significant change before such a diagnosis. These results suggest that WtP in training sessions is a potential behavioural measure of dolphin welfare, and an indicator of early changes in the dolphins’ health state. We therefore suggest measurement of WtP as a more practical and non-invasive tool to support veterinary care and general management. More work needs to be conducted to elucidate the influence of social behaviour on health, and to identify other potential welfare indicators, but this long-term study has shown that qualitative measures can be both practical and valid when assessing dolphin welfare.

Contemporary discussions about operational definition often hark back to Stanley Smith Stevens’ classic papers on psychological operationism (1935ab). Still, he was far from the only psychologist to call for conceptual hygiene. Some of Stevens’ direct colleagues at Harvard---most notably B. F. Skinner and E. G. Boring---were also actively applying Bridgman’s conceptual strictures to the study of mind and behavior. In this paper, I shed new light on the history of operationism by reconstructing the Harvard debates about operational definition in the (...) years before Stevens published his seminal articles. Building on a large set of archival evidence from the Harvard University Archives, I argue that we can get a more complete understanding of Stevens’ contributions if we better grasp the operationisms of his former teachers and direct colleagues at Harvard’s Department of Philosophy and Psychology.

An important open problem in Reverse Mathematics is the reduction of the first-order strength of the base theory from IΣ1IΣ1 to IΔ0+expIΔ0+exp. The system ERNA, a version of Nonstandard Analysis based on the system IΔ0+expIΔ0+exp, provides a partial solution to this problem. Indeed, weak Königʼs lemma and many of its equivalent formulations from Reverse Mathematics can be ‘pushed down’ into ERNA, while preserving the equivalences, but at the price of replacing equality with ‘≈’, i.e. infinitesimal proximity . The logical principle (...) corresponding to weak Königʼs lemma is the universal transfer principle from Nonstandard Analysis. Here, we consider the intermediate and mean value theorem and their uniform generalizations. We show that ERNAʼs Reverse Mathematics mirrors the situation in classical Reverse Mathematics. This further supports our claim from Sanders [19] that the Reverse Mathematics of ERNA plus universal transfer is a copy up to infinitesimals of that of WKL0. We discuss some of the philosophical implications of our results. (shrink)

This essay is an attempt to plumb the conventions which exist at a specific historical moment in both the aesthetic and scientific spheres. I will assume the existence of a web of conventions within the world of the aesthetic—conventions which have elsewhere been admirably illustrated—but will depart from the norm by examining the synchronic existence of another series of conventions, those of medicine. I do not mean in any way to accord special status to medical conventions. Indeed, the world is (...) full of overlapping and intertwined systems of conventions, of which the medical and the aesthetic are but two. Medicine offers an especially interesting source of conventions since we do tend to give medical conventions special “scientific” status as opposed to the “subjective” status of the aesthetic conventions. But medical icons are no more “real” than “aesthetic” ones. Like aesthetic icons, medical icons may iconographic in that they represent these realities in a manner determined by the historical position of the observers, their relationship to their own time, and to the history of the conventions which they employ. Medicine uses its categories to structure an image of the diversity of mankind; it is as much at the mercy of the needs of any age to comprehend this infinite diversity as any other system which organizes our perception of the world. The power of medicine, at least in the nineteenth century, lies in the rise of the status of science. He conventions of medicine infiltrate other seemingly closed iconographic systems precisely because of this status. In examining the conventions of medicine employed in other areas, we must not forget this power.One excellent example of the conventions of human diversity captured in the iconography of the nineteenth century is the linkage of two seemingly unrelated female images—the icon of the Hottentot female and the icon of the prostitute. In the course of the nineteenth century, the female Hottentot comes to represent the black female in nuce, and the prostitute to represent the sexualized woman. Both of these categories represent the creation of classes which correspondingly represent very specific qualities. While the number of terms describing the various categories of the prostitute expanded substantially during the nineteenth century, all were used to label the sexualized woman. Likewise, while many groups of African blacks were known to Europeans in the nineteenth century, the Hottentot remained representative of the essence of the black, especially the black female. Both concepts fulfilled an iconographic function in the perception and the representation of the world. How these two concepts were associated provides a case study for the investigation of patterns of conventions, without any limitation on the “value” of one pattern over another. Sander L. Gilman is professor of Humane Studies in the Department of German Literature and Near Eastern Studies and professor of Psychiatry in the Cornell Medical College, Cornell University.

The principle aim of this thesis is to provide an account of the nature of health. The starting-point is that health is a normative concept: health implies a standard or norm in relation to which an organism’s state is evaluated. Many philosophers take this to imply that health must be defined in subjective terms. They either think health consists in a certain type of subjective experience, or that health is relative to subjective values and goals. I argue that subjective definitions (...) of health fail to capture the essential properties of health and attempt to show that health is something normative and yet entirely objective. This would imply that there are normative facts in the world, and to support this claim I turn to debates in contemporary meta-ethics. I develop a meta-ethical theory according to which a subset of non-moral goods is grounded in objective features of living beings, and argue that this meta-ethical theory opens the possibility for an objective account of health. I then proceed to develop a theory of health that aims to capture what it means for any living to be healthy. I argue that the concept of health latches onto organisms’ capacities : the greater an organism’s range of capacities, i.e. the more it is capable of doing, the healthier it is. The norm relative to which an organism’s range of capacities is measured in evaluations of health, I go on to argue, is the maximum range of capacities possible for the species. Accordingly, an organism is healthy if it is capable of performing all species-specific activities. A closer analysis of this claim yields the formal definition that health consists in a multiplicity of potential activity vis-à-vis factual limitations set by the species. This definition of health is defended against various objections and potential counterexamples. In the context of human health, I attempt to show this definition of health captures both physical and mental dimensions of health; that it establishes a direct link between health and individual autonomy; and that it supports a Nietzschean account of ‘the greathealth’—the idea that being able to give up the concern for one’s health constitutes a superior kind of health. In the conclusions, I reflect on whether this conception of health could function as an ethical ideal, and consider the form that a health-based ethics could take. (shrink)

The utility of recognising emotion expressions for coordinating social interactions is well documented, but less is known about how continuously changing emotion displays are perceived. The nonlinear dynamic systems view of emotions suggests that mixed emotion expressions in the middle of displays of changing expressions may be decoded differently depending on the expression origin. Hysteresis is when an impression (e.g., disgust) persists well after changes in facial expressions that favour an alternative impression (e.g., anger). In expression changes based on photographs (...) (Study 1) and avatar images (Studies 2a–c, 3), we found hystereses particularly in changes between emotions that are perceptually similar (e.g., anger–disgust). We also consistently found uncertainty (neither emotion contributing to the mixed expression was perceived), which was more prevalent in expression sequences than in static images. Uncertainty occurred particularly in changes between emotions that are perceptually dissimilar, such as changes between happiness and negative emotions. This suggests that the perceptual similarity of emotion expressions may determine the extent to which hysteresis and uncertainty occur. Both hysteresis and uncertainty effects support our premise that emotion decoding is state dependent, a characteristic of dynamic systems. We propose avenues to test possible underlying mechanisms.

Moral reasoning traditionally distinguishes two types of evil: moral and natural. The standard view is that ME is the product of human agency and so includes phenomena such as war, torture and psychological cruelty; that NE is the product of nonhuman agency, and so includes natural disasters such as earthquakes, floods, disease and famine; and finally, that more complex cases are appropriately analysed as a combination of ME and NE. Recently, as a result of developments in autonomous agents in cyberspace, (...) a new class of interesting and important examples of hybrid evil has come to light. In this paper, it is called artificial evil and a case is made for considering it to complement ME and NE to produce a more adequate taxonomy. By isolating the features that have led to the appearance of AE, cyberspace is characterised as a self-contained environment that forms the essential component in any foundation of the emerging field of Computer Ethics. It is argued that this goes some way towards providing a methodological explanation of why cyberspace is central to so many of CE’s concerns; and it is shown how notions of good and evil can be formulated in cyberspace. Of considerable interest is how the propensity for an agent’s action to be morally good or evil can be determined even in the absence of biologically sentient participants and thus allows artificial agents not only to perpetrate evil but conversely to ‘receive’ or ‘suffer from’ it. The thesis defended is that the notion of entropy structure, which encapsulates human value judgement concerning cyberspace in a formal mathematical definition, is sufficient to achieve this purpose and, moreover, that the concept of AE can be determined formally, by mathematical methods. A consequence of this approach is that the debate on whether CE should be considered unique, and hence developed as a Macroethics, may be viewed, constructively, in an alternative manner. The case is made that whilst CE issues are not uncontroversially unique, they are sufficiently novel to render inadequate the approach of standard Macroethics such as Utilitarianism and Deontologism and hence to prompt the search for a robust ethical theory that can deal with them successfully. The name Information Ethics is proposed for that theory. It is argued that the uniqueness of IE is justified by its being non-biologically biased and patient-oriented: IE is an Environmental Macroethics based on the concept of data entity rather than life. It follows that the novelty of CE issues such as AE can be appreciated properly because IE provides a new perspective. In light of the discussion provided in this paper, it is concluded that Computer Ethics is worthy of independent study because it requires its own application-specific knowledge and is capable of supporting a methodological foundation, Information Ethics.

Abstract:We analyzed co-citation patterns in 332,498 articles published in Anglophone psychology journals between 1946 and 1990 to estimate (1) when cognitive psychology first emerged as a clearly delineated subdiscipline, (2) how fast it grew, (3) to what extent it replaced other (e.g., behaviorist) approaches to psychology, (4) to what degree it was more appealing to scholars from a younger generation, and (5) whether it was more interdisciplinary than alternative traditions. We detected a major shift in the structure of co-citation networks (...) between approximately 1955 and 1975 and draw novel conclusions about the developments commonly referred to as "the cognitive turn.".
