In a recent commentary, Memmert critiqued claims that attentional misdirection is directly analogous to inattentional blindness and cautioned against assuming too close a similarity between the two phenomena. One important difference highlighted in his analysis is that most lab-based inductions of IB rely on the taxing of attention through a demanding primary task, whereas attentional misdirection typically involves simply the orchestration of spatial attention. The present commentary argues that, rather than reflecting a complete dissociation between IB and attentional misdirection, (...) this difference highlights potential grounds for delineating mechanistically distinct forms of IB: spatial inattentional blindness, which stems from the covert misallocation of spatial attention, and central inattentional blindness, which stems from disruption or preoccupation of perceptual mechanisms that interface with higher-level processes such as working memory. Recognition of such distinctions can help situate theoretical understanding of IB more firmly within the context of the broader attention literature. (shrink)

Predictive genetic testing is now routinely offered to asymptomatic adults at risk for genetic disease. However, testing of minors at risk for adult-onset conditions, where no treatment or preventive intervention exists, has evoked greater controversy and inspired a debate spanning two decades. This review aims to provide a detailed longitudinal analysis and concludes by examining the debate's current status and prospects for the future. Fifty-three relevant theoretical papers published between 1990 and December 2010 were identified, and interpretative content analysis was (...) employed to catalogue discrete arguments within these papers. Novel conclusions were drawn from this review. While the debate's first voices were raised in opposition of testing and their arguments have retained currency over many years, arguments in favour of testing, which appeared sporadically at first, have gained momentum more recently. Most arguments on both sides are testable empirical claims, so far untested, rather than abstract ethical or philosophical positions. The dispute, therein, lies not so much in whether minors should be permitted to access predictive genetic testing but whether these empirical claims on the relative benefits or harms of testing should be assessed.

This remarkable book is the most comprehensive study ever written of the history of moral philosophy in the seventeenth and eighteenth centuries. Its aim is to set Kant's still influential ethics in its historical context by showing in detail what the central questions in moral philosophy were for him and how he arrived at his own distinctive ethical views. The book is organised into four main sections, each exploring moral philosophy by discussing the work of many influential philosophers of (...) the seventeenth and eighteenth centuries. In an epilogue the author discusses Kant's view of his own historicity, and of the aims of moral philosophy. In its range, in its analyses of many philosophers not discussed elsewhere, and in revealing the subtle interweaving of religious and political thought with moral philosophy, this is an unprecedented account of the evolution of Kant's ethics.

On the most popular account of material constitution, it is common for a material object to coincide precisely with one or more other material objects, ones that are composed of just the same matter but differ from it in sort. I argue that there is nothing that could ground the alleged difference in sort and that the account must be rejected.

Previous research has demonstrated how emotion resembling cues in the face help shape impression formation. Perhaps most notable in the literature to date, has been work suggesting that gender-related appearance cues are visually confounded with certain stereotypic expressive cues. Only a couple studies to date have used computer vision to directly map out and test facial structural resemblance to emotion expressions using facial landmark coordinates to estimate face shape. In one study using a Bayesian network classifier trained to detect (...) emotional expressions structural resemblance to a specific expression on a non-expressive face was found to influence trait impressions of others. In another study, a connectionist model trained to detect emotional expressions found different emotion-resembling cues in male vs. female faces. Despite this seminal work, direct evidence confirming the theoretical assertion that humans likewise utilize these emotion-resembling cues when forming impressions has been lacking. Across four studies, we replicate and extend these prior findings using new advances in computer vision to examine gender-related, emotion-resembling structure, color, and texture and their impact on gender-stereotypic impression formation. We show that all three are meaningfully related to human impressions of emotionally neutral faces. Further when applying the computer vision algorithms to experimentally manipulate faces, we show that humans derive similar impressions from them as did the computer. (shrink)

Readers of fiction tend to have better abilities of empathy and theory of mind. We present a study designed to replicate this finding, rule out one possible explanation, and extend the assessment of social outcomes. In order to rule out the role of personality, we first identified Openness as the most consistent correlate. This trait was then statistically controlled for, along with two other important individual differences: the tendency to be drawn into stories and gender. Even after accounting for (...) these variables, fiction exposure still predicted performance on an empathy task. Extending these results, we also found that exposure to fiction was positively correlated with social support. Exposure to nonfiction, in contrast, was associated with loneliness, and negatively related to social support. (shrink)

We present statistical analyses of the large‐scale structure of 3 types of semantic networks: word associations, WordNet, and Roget's Thesaurus. We show that they have a small‐world structure, characterized by sparse connectivity, short average path lengths between words, and strong local clustering. In addition, the distributions of the number of connections follow power laws that indicate a scale‐free pattern of connectivity, with most nodes having relatively few connections joined together through a small number of hubs with many connections. These (...) regularities have also been found in certain other complex natural networks, such as the World Wide Web, but they are not consistent with many conventional models of semantic organization, based on inheritance hierarchies, arbitrarily structured networks, or high‐dimensional vector spaces. We propose that these structures reflect the mechanisms by which semantic networks grow. We describe a simple model for semantic growth, in which each new word or concept is connected to an existing network by differentiating the connectivity pattern of an existing node. This model generates appropriate small‐world statistics and power‐law connectivity distributions, and it also suggests one possible mechanistic basis for the effects of learning history variables (age of acquisition, usage frequency) on behavioral performance in semantic processing tasks.

Objectives: To explore how subjects in a placebo-controlled vitamin A supplementation trial among Ghanaian women aged 15–45 years perceive the trial and whether they know that not all trial capsules are the same, and to identify factors associated with this knowledge.Methods: 60 semistructured interviews and 12 focus groups were conducted to explore subjects’ perceptions of the trial. Steps were taken to address areas of low comprehension, including retraining fieldworkers. 1971 trial subjects were randomly selected for a survey measuring their knowledge (...) that not all trial capsules are the same. The subjects’ fieldworkers were also interviewed about their characteristics and trial knowledge. Factors associated with knowledge were explored using multi-level modeling.Results: Although subjects knew they were taking part in research, most thought they were receiving an active and beneficial medication. Variables associated with knowledge were education and district of residence. Radio broadcasts benefited those with some schooling. Fieldworkers’ characteristics were not associated with subjects’ knowledge.Conclusions: Research and debate on new or improved consent procedures are urgently required, particularly for subjects with little education.

Delays in early language development are characteristic of young autistic children, and one of the most recognizable first concerns that motivate parents to seek a diagnostic evaluation for their child. Although early language abilities are one of the strongest predictors of long-term outcomes, there is still much to be understood about the role of language impairment in the heterogeneous phenotypic presentation of autism. Using a person-centered, Latent Profile Analysis, we first aimed to identify distinct patterns of language and social (...) communication ability in a clinic-based sample of 498 autistic children, ranging in age from 18 to 60 months. Next, a multinomial logistic regression analysis was implemented to examine sociodemographic and child-based developmental differences among the identified language and social communication profiles. Three clinically meaningful profiles were identified from parent-rated and clinician-administered measures: Profile 1 “Relatively Low Language and Social Communication Abilities,” Profile 2 “Relatively Elevated Language and Social Communication Abilities,” and Profile 3 “Informant Discrepant Language and Relatively Elevated Social Communication Abilities.” Overall, young autistic children from the lowest-resource households exhibited the lowest language and social communication abilities, and the lowest non-verbal problem-solving and fine-motor skills, along with more features of attention-deficit/hyperactivity disorder and atypical auditory processing. These findings highlight the need for effective community-based implementation strategies for young autistic children from low-resource households and underrepresented communities to improve access to individualized quality care.

Fetal tissue transplants have now been successful in primates, raising the possibility of treatment for Parkinson's disease and other chronic illnesses. Whether or not abortion is morally justified, use of human fetal tissue for research or therapy is justified in certain circumstances. The rationale, both for permitting transplantation of fetal tissue and for limitations in exercising the technology, is based on the same set of ethical principles that supported restrictive legislation in the past: respect for autonomy and a balancing of (...) harms and benefits that gives priority to those most affected.

This book highlights some of the most pressing safety, ethical, legal and societal issues related to the diverse contexts in which robotic technologies apply. Focusing on the essential concept of well-being, it addresses topics that are fundamental not only for research, but also for industry and end-users, discussing the challenges in a wide variety of applications, including domestic robots, autonomous manufacturing, personal care robots and drones.

This article contributes empirical findings and sociological theoretical perspectives to discussions of the role of community lay health workers, including in improving the health of individuals and communities. We focus on the role of the Health Trainer (HT), at its inception described as one of the most innovative developments in UK Public Health policy. As lay health workers, HTs are tasked with reducing health inequalities in disadvantaged communities by supporting clients to engage in healthier lifestyles. HTs are currently sociologically (...) under-researched, particularly in relation to occupational identity work, and the boundary work undertaken inter-occupationally with other health workers. To address this research lacuna, a qualitative study was undertaken with 25 HTs based in the Midlands region of the UK. In theorising our findings, we employ a novel combination of symbolic interactionist conceptualisation of 1) identity work, and of 2) boundary work. The article advances knowledge in the field of health and exercise by investigating and theorising how HTs construct, work at, manage, and communicate about professional/occupational boundaries, in order to provide personalised support to their clients in achieving and sustaining healthy behaviour change within the constraints of clients’ lifeworlds.

Habits and habitudes are peculiar in that they are both a condition of human agency, as well as one of its most significant hurdles. They open up the world by providing us with ways of being within it (e.g., how we perceive, move about, and generally orient ourselves in space). However, they also confine our worldly behavior given their repetitive and often predictable nature. This tension between spontaneity and repetition arises out of the two-fold temporal structure of habits – (...) i.e., the habitual body simultaneously directs us toward the future and the past. An understanding of this tension is generally important for thinking about how individuals can do things differently. More urgently, this work has applications in the treatment of addictions and other compulsive behaviors where the difficulties of disrupting habitual repetition are much more pronounced. (shrink)

Keystream sequences should look as random as possible, i.e. should present no logical pattern to be exploited in cryptographic attacks. The generalized self-shrinking generator, a sequence generator based on irregular decimation, produces a family of sequences with good cryptographic properties. In this work, we display a detailed analysis on the randomness of the sequences resulting from the concatenation of elements of this family. We apply the most important batteries of statistical and graphical tests providing powerful results and a new (...) method to construct sequences with good cryptographic properties. (shrink)

Aim: To assess ethical issues in everyday clinical practice among physicians and nurses of the University Hospital Rijeka, Rijeka, Croatia.Subjects and methods: We surveyed the entire population of internal medicine, oncology and intensive care specialists and associated nurses employed at the University Hospital Rijeka, Rijeka, Croatia . An anonymous questionnaire was used to explore the type and frequency of ethical dilemmas, rank of their difficulty, access to and use of ethics support services, training in ethics and confidence about knowledge in (...) ethics. Physicians ranged in age from 27 to 61 years, and nurses , from 20 to 52.Results: The most frequent ethical dilemmas concerned uncertain or impaired decision-making capacity , limitation of treatment at the end of life and disagreements among family members . The most difficult dilemmas concerned euthanasia and physician-assisted suicide and limitation of treatment at the end of life . Only a minority reported ever using any kind of ethics support services or being very confident about knowledge in ethics .Conclusions: Similar ethical difficulties are present in the clinical practice of both physicians and nurses, with important differences in access and use of ethics support services. A need for systematic ethics educational activities was identified. Inclusion of individual ethics consultants in Croatian healthcare ethics support services is strongly advised. (shrink)

The increasing demand for horticultural products for nutritional and economic purposes by lesser developed countries (LDC's) is well-documented. Technological demands of the LDC's producing horticultural products is also increasing. Pesticide use is an integral component of most agricultural production, yet chemicals are often supplied without supplemental information vital for their safe and efficient implementation. Illiteracy rates in developing countries are high, making pesticide education even more challenging. For women, who perform a significant share of agricultural tasks, illiteracy rates are (...) even higher than for men. The dilemma exists of how a developing country can improve its nutritional and economic situation without giving consideration to social and environmental consequences. (shrink)

Oral healthcare is attracting much attention after decades of neglect from policymakers. Recent studies have shown a strong association between oral and overall health, which can lead to serious health problems. Availability of oral healthcare services is an essential part of ensuring universal healthcare coverage. More importantly, current gaps in its accessibility by minority or marginalized population groups are crucial public health as well as ethical concerns. One notable effort to address this issue comes from Non-Governmental Organizations (NGOs), which offer (...) oral healthcare services for non-insured refugees. However, the challenge remains that these care services are not comprehensive, which has implications for the refugees’ oral and general health. In this article, we discuss this complex issue in the German healthcare context by including ethical reflections. Therefore, the purpose of this article is to discuss the ethical challenges related to oral healthcare services provided by NGOs for refugees in Germany. First, we will introduce the general oral healthcare context worldwide and in Germany. Second, we will provide a general description of the oral healthcare services provided by NGOs for refugees in Germany, as well as an overview of existing gaps. This will provide us with the context for our third and most important task—discussing the ethical implications of the gaps. In doing so, and since the ethical implications can be several, we demarcate the scope of our analysis by focusing on the specific ethical issues of justice, harm, and autonomy. Finally, we offer some recommendations for how to move forward. (shrink)

The tendency in the past has been for aruhropobgists to rationalize away the native claim that spirits exist. But in this study, a number of incidents, some of which happened to the author, are described and used to bring this positwistic assumption into question. The author shows that "participant observation" in the fullest sense requires taking the final leap and "going native" in the most complete way possible.

We investigated how color preferences vary according to season and whether those changes could be explained by the ecological valence theory. To do so, we assessed the same participants’ preferences for the same colors during fall, winter, spring, and summer in the northeastern United States, where there are large seasonal changes in environmental colors. Seasonal differences were most pronounced between fall and the other three seasons. Participants liked fall-associated dark-warm colors—for example, dark-red, dark-orange, dark-yellow, and dark-chartreuse—more during fall than (...) other seasons. The EVT could explain these changes with a modified version of Palmer and Schloss’ weighted affective valence estimate procedure that added an activation term to the WAVE equation. The results indicate that color preferences change according to season, as color-associated objects become more/less activated in the observer. These seasonal changes in color preferences could not be characterized by overall shifts in weights along cone-contrast axes. (shrink)

Aim: To examine how physicians’ life stances affect their attitudes to end-of-life decisions and their actual end-of-life decision-making.Methods: Practising physicians from various specialties involved in the care of dying patients in Belgium, Denmark, The Netherlands, Sweden, Switzerland and Australia received structured questionnaires on end-of-life care, which included questions about their life stance. Response rates ranged from 53% in Australia to 68% in Denmark. General attitudes, intended behaviour with respect to two hypothetical patients, and actual behaviour were compared between all large (...) life-stance groups in each country.Results: Only small differences in life stance were found in all countries in general attitudes and intended and actual behaviour with regard to various end-of-life decisions. However, with regard to the administration of drugs explicitly intended to hasten the patient’s death , physicians with specific religious affiliations had significantly less accepting attitudes, and less willingness to perform it, than non-religious physicians. They had also actually performed PAD less often. However, in most countries, both Catholics and Protestants reported ever having made such a decision.Discussion: The results suggest that religious teachings influence to some extent end-of-life decision-making, but are certainly not blankly accepted by physicians, especially when dealing with real patients and circumstances. Physicians seem to embrace religious belief in a non-imperative way, allowing adaptation to particular situations. (shrink)

The notion of an individual and the related issues on individuation are topics that appear in the philosophical discussion ever since the antiquity. The idea of an individual thing is intuitively clear: an individual is something of a specific kind that is a unity, having its own identity, and being so that it is possible at least in principle to discern it from any other individual, even of similar species. But when we try to leave the intuitive realm and push (...) this idea to a logical analysis, we find a cluster of problems that are difficult to overcome within standard logico-mathematical contexts. In this work, we shall be concerned with some aspects of this intuitive concept of an individual and on some related facts about individuation taken from recent discussions that arose ever since the inception of quantum theory, pushing the discussion to a “logical” view, which in our opinion is still lacking in the usual debates on such issues. In the final part of the paper, we propose a metaphysics where the notion of identity is substituted, for some objects, by a weaker notion of indiscernibility, and we try to justify such a move. In most of the uses of the expression “quantum theory”, we shall not make explicit the distinction between the non-relativistic and the relativistic approaches, although they of course are quite different, for we think that the problems as we shall present them appear in both versions. But, as the text goes, the context will distinguish between them and these questions will become clear to the reader. (shrink)

Due to the socio-demographic change in most developed western countries, elderly populations have been continuously increasing. Therefore, preventive and assistive systems that allow elderly people to independently live in their own homes as long as possible will become an economical if not ethical necessity. These respective technologies are being developed under the term "Ambient Assistive Technologies". The EU-funded AAT-project Ambient Lighting Assistance for an Ageing Population has established the long-term goal to create an adaptive system capable of improving the (...) residential lighting conditions of single living elderly persons also aiming at supporting the preservation of their independence. Results of an earlier survey revealed that the elderly perceived their current lighting situation as satisfactory, whereas interviewers assessed in-house lighting as too dark and risk-laden. The overall results of ALADIN showed a significant increase in well-being from the baseline final testing with the new adaptive lighting system. Positive results for wellbeing and life quality suggest that the outcome effects may be attributed to the introduction of technology as well as to social contacts arising from participating in the study. The technological guidance of the study supervisors, in particular, may have produced a strong social reactivity effect that was first observed in the famous Hawthorne experiments in the 1930s. As older adults seem to benefit both from meaningful social contacts as well as assistive technologies, the question arises how assistive technology can be socially embedded to be able to maximize positive health effects. Therefore ethical guidelines for development and use of new assistive technologies for handicapped/older persons have to be developed and should be discussed with regard to their applicability in the context of AAT.

Zabarella and the Intentionality of Sensation - ABSTRACT: In this paper, I examine Zabarella’s account of the intentionality of sensation. By looking at both his account of the production of the sensible species as well as proper activity of the human soul in the process of sensation, I show that he has carefully reinterpreted standard medieval theories of sensation. Most notably, his account of intentionality as a kind of mental attention seems to point towards a type of Cartesian dualism, (...) but at the same time attempts to remain faithful to the basic insights of the Aristotelian tradition concerning sensation.

Poised on the cusp between phenomenology and materiality, media institute a theoretical oscillation that promises to displace the empirical-transcendental divide that has structured western meditation on thinking, including the thinking of technics. Because media give the infrastructure conditioning thought without ceasing to be empirical (i.e. without functioning as a transcendental condition), they form the basis for a complex hermeneutics that cannot avoid the task of accounting for its unthematizable infrastructural condition. Tracing the oscillation constitutive of such a hermeneutics as it (...) serves variously to constitute media theory in the work of critics from McLuhan to Kittler, from Leroi-Gourhan to Stiegler, my interrogation ultimately conceptualizes the medium as an environment for life:by giving concrete form to ‘epiphylogenesis’ (the exteriorization of human evolution), concrete media find their most ‘originary’ function not as artifacts but via their participation in human technogenesis (our co-evolution with technics).

ObjectiveHead and neck cancer treatments are known to significantly affect functionality and appearance, leading to an increased risk for body image disturbances. Yet, few longitudinal studies exist to examine body image in these patients. Based on a conceptual model, the current study aimed to determine, in patients newly diagnosed with HNC: the prevalence, level, and course of body image concerns; correlates of upon cancer diagnosis body image concerns; predictors of immediate post-treatment body image concerns; and association between body image concerns (...) and levels of anxiety, depression, suicidal ideation, support, and alcohol and drug misuse.MethodsTwo hundred and twenty-three, newly diagnosed with a primary HNC were assessed using structured clinical interviews and psychometric measures at three, and 6 months after diagnosis. Primary outcome was 3-month, as it was most salient to body image disturbance. Multiple linear regression analyses were conducted on the potential body image predictors, based on the model.ResultsSixty-eight percent of patients with HNC presented some level of body image concerns. Body image concerns at baseline and post-treatment were significantly related and significantly increased from pre- to post-treatment. Immediately post-treatment, 89% presented some level of body image concerns. Correlates of body image concerns in patients with HNC at baseline included: physical symptom burden, difficulties with communication and eating, coping with the cancer diagnosis using denial, suicidal ideation, and having had a past anxiety diagnosis. When controlling for sociodemographic and medical variables, body image concerns in patients with HNC in the immediate post-treatment were predicted by: baseline body image, physical symptom burden, and neuroticism.ConclusionThis longitudinal study helps identify patients more susceptible to experience body image disturbance following head and neck cancer. Clinicians ought to pay special attention to body image concerns upon cancer diagnosis, physical symptom burden, and neuroticism, and may want to target these factors in future preventive interventions.

Does physics describe anything that can meaningfully be called “independent reality,” or is it merely operational? Most physicists implicitly favor an intermediate standpoint, which takes quantum physics into account, but which nevertheless strongly holds fast to quite strictly realistic ideas about apparently “obvious facts” concerning the macro-objects. Part 1 of this article, which is a survey of recent measurement theories, shows that, when made explicit, the standpoint in question cannot be upheld. Part 2 brings forward a proposal for making (...) minimal changes to this standpoint in such a way as to remove such objections. The “empirical reality” thus constructed is a notion that, to some extent,does ultimately refer to the human means of apprehension and of data processing. It nevertheless cannot be said that it reduces to a mere name just labelling a “set of recipes that never fail.” It is shown that our usual notion of macroscopic causality must be endowed with similar features.

Stakeholder theory has received greater scholarly and practitioner attention as organizations consider the interests of various groups affected by corporate operations, including employees. This study investigates two dimensions of psychological climate, specifically perceived pay equity and diversity climate, for one such stakeholder group: racioethnic minority professionals. We examined the main effect of U.S. professionals’ of color pay equity perceptions, and the influence of perceived internal and external pay equity on turnover intentions. We also investigated the interactive effect of perceptions of (...) pay equity and diversity climate on turnover intentions. Results indicated that pay equity perceptions were negatively associated with turnover intentions. Our findings showed that perceptions of internal pay equity influenced turnover intentions but perceptions of external equity did not. Further, perceptions of pay equity and the diversity climate interactively influenced turnover intentions. Participants who reported an unfavorable diversity climate and a low perceived pay equity were most likely to report turnover intentions. Simple slope analysis for moderate pay equity also was significant. When perceived pay equity was high, favorability of the diversity climate did not affect turnover intentions. The findings have useful practical implications. When pay was perceived as equitable, participants appeared to pay less attention to the diversity climate. Employee pay equity perceptions may be malleable; sharing information with employees about pay levels during performance reviews may enhance perceptions of pay equity. The findings suggest that, consistent with stakeholder theory, organizations should attend to perceptions of both pay equity and diversity climate when striving to minimize the turnover intentions of professionals of color.

In the chapter of Difference and Repetition entitled ‘Ideas and the synthesis of difference,’ Deleuze mobilizes mathematics to develop a ‘calculus of problems’ that is based on the mathematical philosophy of Albert Lautman. Deleuze explicates this process by referring to the operation of certain conceptual couples in the field of contemporary mathematics: most notably the continuous and the discontinuous, the infinite and the finite, and the global and the local. The two mathematical theories that Deleuze draws upon for this (...) purpose are the differential calculus and the theory of dynamical systems, and Galois’ theory of polynomial equations. For the purposes of this paper I will only treat the first of these, which is based on the idea that the singularities of vector fields determine the local trajectories of solution curves, or their ‘topological behaviour’. These singularities can be described in terms of the given mathematical problematic, that is for example, how to solve two divergent series in the same field, and in terms of the solutions, as the trajectories of the solution curves to the problem. What actually counts as a solution to a problem is determined by the specific characteristics of the problem itself, typically by the singularities of this problem and the way in which they are distributed in a system. Deleuze understands the differential calculus essentially as a ‘calculus of problems’, and the theory of dynamical systems as the qualitative and topological theory of problems, which, when connected together, are determinative of the complex logic of different/ciation. (DR 209). Deleuze develops the concept of a problematic idea from the differential calculus, and following Lautman considers the concept of genesis in mathematics to ‘play the role of model ... with respect to all other domains of incarnation’. While Lautman explicated the philosophical logic of the actualization of ideas within the framework of mathematics, Deleuze (along with Guattari) follows Lautman’s suggestion and explicates the operation of this logic within the framework of a multiplicity of domains, including for example philosophy, science and art in What is Philosophy?, and the variety of domains which characterise the plateaus in A Thousand Plateaus. While for Lautman, a mathematical problem is resolved by the development of a new mathematical theory, for Deleuze, it is the construction of a concept that offers a solution to a philosophical problem; even if this newly constructed concept is characteristic of, or modelled on the new mathematical theory.

Two property regimes for software development may be distinguished. Within corporations, on the one hand, a Private Regime obtains which excludes all outsiders from access to a firm's software assets. It is shown how the protective instruments of secrecy and both copyright and patent have been strengthened considerably during the last two decades. On the other, a Public Regime among hackers may be distinguished, initiated by individuals, organizations or firms, in which source code is freely exchanged. It is argued that (...) copyright is put to novel use here: claiming their rights, authors write `open source licenses' that allow public usage of the code, while at the same time regulating the inclusion of users. A `regulated commons' is created. The analysis focuses successively on the most important open source licenses to emerge, the problem of possible incompatibility between them (especially as far as the dominant General Public License is concerned), and the fragmentation into several user communities that may result.

: The two main psychological theories of the ordinary conditional were designed to account for inferences made from assumptions, but few premises in everyday life can be simply assumed true. Useful premises usually have a probability that is less than certainty. But what is the probability of the ordinary conditional and how is it determined? We argue that people use a two stage Ramsey test that we specify to make probability judgements about indicative conditionals in natural language, and we describe (...) experiments that support this conclusion. Our account can explain why most people give the conditional probability as the probability of the conditional, but also why some give the conjunctive probability. We discuss how our psychological work is related to the analysis of ordinary indicative conditionals in philosophical logic. (shrink)

This thematic bibliography provides a narrative account of the most important literature comprising, and about, the 1930s debates about Christian carried out by Etienne Gilson, Jacques Maritain, Maurice Blondel, Emile Brehier, Gabriel Marcel, and many others.

John Rawls’s political liberalism and its ideal of public reason are tremendously influential in contemporary political philosophy and in constitutional law as well. Many, perhaps even most, liberals are Rawlsians of one stripe or another. This is problematic, because most liberals also support the redefinition of civil marriage to include same-sex unions, and as I show, Rawls’s political liberalism actually prohibits same- sex marriage. Recently in Perry v. Schwarzenegger, however, California’s northern federal district court reinterpreted the traditional rational (...) basis review in terms of liberal neutrality akin to Rawls’s “public reason,” and overturned Proposition 8 and established same-sex marriage. (This reinterpretation was amplified in the 9th Circuit Court’s decision upholding the district court on appeal in Perry v. Brown.) But on its own grounds Perry should have drawn the opposite conclusion. This is because all the available arguments for recognizing same-sex unions as civil marriages stem from controversial comprehensive doctrines about the good, and this violates the ideal of public reason; yet there remains a publicly reasonable argument for traditional marriage, which I sketch here. In the course of my argument I develop Rawls’s politically liberal account of the family by drawing upon work by J. David Velleman and H. L. A. Hart, and discuss the implications of this account for political theory and constitutional law. (shrink)

This penetrating book sheds light on the psychology of fundamentalism, with a particular focus on those who become extremists and fanatics. What accounts for the violence that emerges among some fundamentalist groups? The contributors to this book identify several factors: a radical dualism, in which all aspects of life are bluntly categorized as either good or evil; a destructive inclination to interpret authoritative texts, laws, and teachings in the most literal of terms; an extreme and totalized conversion experience; paranoid (...) thinking; and an apocalyptic world view. After examining each of these concepts in detail, and showing the ways in which they lead to violence among widely disparate groups, these engrossing essays explore such areas as fundamentalism in the American experience and among jihadists, and they illuminate aspects of the same psychology that contributed to such historical crises as the French Revolution, the Nazi movement, and post-Partition Hindu religious practice.

In this article I give an overview of some recent work in philosophy of science dedicated to analysing the scientific process in terms of (conceptual) mathematical models of theories and the various semantic relations between such models, scientific theories, and aspects of reality. In current philosophy of science, the most interesting questions centre around the ways in which writers distinguish between theories and the mathematical structures that interpret them and in which they are true, i.e. between scientific theories as (...) linguistic systems and their non-linguistic models. In philosophy of science literature there are two main approaches to the structure of scientific theories, the statement or syntactic approach -- advocated by Carnap, Hempel and Nagel -- and the non- statement or semantic approach --advocated, among others, by Suppes, the structuralists, Beth, Van Fraassen, Giere, Wojcicki. In conclusion, I briefly review some of the usual realist inspired questions about the possibility and character of relations between scientific theories and reality as implied by the various approaches I discuss in the course of the article. The models of a scientific theory should indeed be adequate to the phenomena, but if the theory is 'adequate' to (true in) its conceptual (mathematical) models as well, we have a model-theoretic realism that addresses the possible meaning and reference of 'theoretical entities' without relapsing into the metaphysics typical of the usual scientific realist approaches.

This article examines the changing status of tropical biology by considering the origins and early development of the Barro Colorado Island Biological Laboratory. Today the laboratory is part of a large diversified tropical research center operated by the Smithsonian Institution. However, for most of its history the laboratory led a tenuous existence. Both the early problems and eventual success of the institution can only be explained by considering the interaction of various intellectual, institutional, and broader social factors.

Compared to evidence-based public health, evidence-based medicine is a more familiar phrase. Evidence-based medicine has become increasingly popular in the past decade, due in large part to the emergence of computerized database search technology and advanced statistical tools which allow researchers to quickly identify and summarize vast amounts of scientific information.Today, the concept of evidence-based public health is gaining momentum and has grown in popularity. However, the term “evidence-based” lacks clarification and is subject to a variety of interpretations. The evidence (...) that supports evidence-based medicine or public health may include individual experience, anecdotal information, the content of a single scientific article, or the results of a sophisticated systematic review of scientific literature. The imprecise language used to describe evidence leads to confusion over what types of evidence are most appropriate in answering different types of questions. (shrink)

ABSTRACTEmotional distractors can impair perception of subsequently presented targets, a phenomenon called emotion-induced blindness. Do emotional distractors lose their power to disrupt perception when appearing with increased frequency, perhaps due to desensitisation or enhanced recruitment of proactive control? Non-emotional tasks, such as the Stroop, have revealed that high frequency distractors or conflict lead to reduced interference, and distractor frequency appears to modulate attentional capture by emotional distractors in spatial attention tasks. But emotion-induced blindness is thought to reflect perceptual competition between (...) targets and emotional distractors, and it is unclear whether high frequency emotional stimuli cause less disruption at this relatively early stage of processing.

Time was, notably in the theories of classical and medieval moralists, when virtue figured as the central feature in the conception of moral worth. Today, the notion of virtue has slid into conspicuous disuse. Among a few writers today, one can still detect scattered indications of a return to varieties of this conception of goodness; but in most of the contemporary literature it is safe to say that the deontic and usually co-relative notions of ‘right’, ‘ought’, ‘duty’ and ‘obligation’ (...) now command the primacy that once was virtue’s. In works of this decade, for instance, it is not uncommon to encounter the following kind of statement: “The experience of moral obligation is the central element in the concept of morality.” The replacement of the concept of virtue with the language of “right” and “obligation” is an historical phenomenon whose investigation would probably uncover a number of contributing causes. Quite obviously, for instance, the shift owes a great deal to Kant’s insistence upon the dispassionately legislative function of the moral judgment. Yet even more radically, I think it could be shown that the interpretation of moral experience has too often been invaded with the properly epistemic concerns of certitude and objectivity in the moral judgment—hence the emphasis on the “right”—and too often grounded on the assumption that moral judgments are properly moral only when they measure up to this or that criterion. But it is probably more to the point to suppose that the erosion of virtue within philosophical discourse was brought about as much by its own obfuscation as by any competing counter-insistence upon the legislative models of imperativeness and prescriptivity. If, that is to say, the notion of virtue was displaced as a significant ethical principle, it was because philosophers themselves became unclear as to its origins and nature. More concretely, the demise of the notion of virtue was inevitable when it was cut off from direct participation in human actions and relegated exclusively to the private area of emotions and desires.

Here we elucidate a paradox: how a single chemoattractant‐receptor system in two individuals is used for communication despite the seeming inevitability of self‐excitation. In the filamentous fungus Neurospora crassa, genetically identical cells that produce the same chemoattractant fuse via the homing of individual cell protrusions toward each other. This is achieved via a recently described “ping‐pong” pulsatile communication. Using a generic activator‐inhibitor model of excitable behavior, we demonstrate that the pulse exchange can be fully understood in terms of two excitable (...) systems locked into a stable oscillatory pattern of mutual excitation. The most puzzling properties of this communication are the sudden onset of oscillations with final amplitude, and the absence of seemingly inevitable self‐excitation. We show that these properties result directly from both the excitability threshold and refractory period characteristic of excitable systems. Our model suggests possible molecular mechanisms for the ping‐pong communication. (shrink)

There is another element in ancient Greek philosophy which goes in tandem with this effort to give an account of the physical universe and its parts. It is the reaching out for or the attempt to grasp being, reality, or what is. The thought behind this endeavor seems to have been that there exist certain basic entities which it is incumbent upon philosophers to grasp and in terms of which the generation of and the goings-on in the physical universe are (...) to be explained. While this connection between philosophy and the quest for being is more or less overt in a number of the Greek philosophers, one of its most explicit acknowledgements is made by Plato, who in one dialogue has Socrates refer several times to the philosopher’s search for reality and to philosophy itself as a discipline which liberates the soul so that it may contemplate being or reality.

This paper reports the results of a survey study examining the knowledge, motivations and concerns of egg-share donors and recipients, and assesses the clinical and policy implications of these findings. The survey, combining quantitative and qualitative items, was completed by 48 donors and 38 recipients who took part in an egg-sharing scheme at the London Women's Clinic between 2007 and 2009. Although the most important motivation for all egg-sharers was to have a baby, both donors and recipients displayed multiple (...) motivations, including elements of self-interest and altruism. Many viewed egg-sharing as a reciprocal process in which two women with different needs help one another. The results are reassuring from an ethical and policy perspective: they suggest that if information about egg-sharing was more widely available (especially through general practitioners), more women may consider becoming egg-share donors, gaining swift access to their own treatment and reducing the UK's egg donor shortage.

The path-integral approach to quantum theory of continuous measurements has been developed in preceding works of the author. According to this approach the measurement amplitude determining probabilities of different outputs of the measurement can be evaluated in the form of a restricted path integral (a path integral “in finite limits”). With the help of the measurement amplitude, maximum deviation of measurement outputs from the classical one can be easily determined. The aim of the present paper is to express this variance (...) in a simpler and transparent form of a specific uncertainty principle (called the action uncertainty principle, AUP). The most simple (but weak) form of AUP is δS≳ℏ, whereS is the action functional. It can be applied for simple derivation of the Bohr-Rosenfeld inequality for measurability of gravitational field. A stronger (and having wider application) form of AUP (for ideal measurements performed in the quantum regime) is |∫ ′ t″ (δS[q]/δq(t))Δq(t)dt|≃ℏ, where the paths [q] and [Δq] stand correspondingly for the measurement output and for the measurement error. It can also be presented in symbolic form as Δ(Equation) Δ(Path) ≃ ℏ. This means that deviation of the observed (measured) motion from that obeying the classical equation of motion is reciprocally proportional to the uncertainty in a path (the latter uncertainty resulting from the measurement error). The consequence of AUP is that improving the measurement precision beyond the threshold of the quantum regime leads to decreasing information resulting from the measurement. (shrink)
