It is known that, on average, people adapt their choice of memory strategy to the subjective utility of interaction. What is not known is whether an individual's choices are boundedly optimal. Two experiments are reported that test the hypothesis that an individual's decisions about the distribution of remembering between internal and external resources are boundedly optimal where optimality is defined relative to experience, cognitive constraints, and reward. The theory makes predictions that are tested against data, not fitted to it. The (...) experiments use a no-choice/choice utility learning paradigm where the no-choice phase is used to elicit a profile of each participant's performance across the strategy space and the choice phase is used to test predicted choices within this space. They show that the majority of individuals select strategies that are boundedly optimal. Further, individual differences in what people choose to do are successfully predicted by the analysis. Two issues are discussed: the performance of the minority of participants who did not find boundedly optimal adaptations, and the possibility that individuals anticipate what, with practice, will become a bounded optimal strategy, rather than what is boundedly optimal during training.

Vaccinia virus, the world's oldest vaccine, was used originally for the eradication of smallpox. It is now being genetically engineered to create new live vaccines for use against other infectious agents of medical and veterinary importance. Genes coding for antigens of several pathogens have been linked to vaccinia virus transcriptional regulatory signals and inserted into the vaccinia virus genome. The resultant recombinant viruses are infectious, express the foreign gene, stimulate specific immune responses in vaccinated animals and can protect against disease (...) caused by the corresponding pathogen.

By their very nature, overseas medical missions (and even domestic medical charities such as free clinics ) are designed to serve vulnerable populations. If these groups were capable of protecting their own interests, they would not need the help of medical volunteers: their medical needs would be met through existing government health programs or by utilizing their own resources. Medical volunteerism thus seems like an unfettered good: a charitable activity provided by well-meaning doctors and nurses who want to give of (...) their time, skills, and resources to help those who would not otherwise be able to take care of their medical needs. In this article, I argue that if medical volunteerism is to be good, however, it must always meet certain basic ethical requirements. These requirements may be (and perhaps often are) overlooked in the rush to organize and carry out short-term medical missions. I illustrate my point with special reference to short-term medical missions designed to provide surgical repair of obstetric vesico-vaginal fistula, a condition in which the tissues that normally separate the bladder from the vagina are destroyed by obstetric trauma, leading to continuous and unremitting incontinence in the affected woman.

The National Center for Biomedical Ontology is a consortium that comprises leading informaticians, biologists, clinicians, and ontologists, funded by the National Institutes of Health (NIH) Roadmap, to develop innovative technology and methods that allow scientists to record, manage, and disseminate biomedical information and knowledge in machine-processable form. The goals of the Center are (1) to help unify the divergent and isolated efforts in ontology development by promoting high quality open-source, standards-based tools to create, manage, and use ontologies, (2) to create (...) new software tools so that scientists can use ontologies to annotate and analyze biomedical data, (3) to provide a national resource for the ongoing evaluation, integration, and evolution of biomedical ontologies and associated tools and theories in the context of driving biomedical projects (DBPs), and (4) to disseminate the tools and resources of the Center and to identify, evaluate, and communicate best practices of ontology development to the biomedical community. Through the research activities within the Center, collaborations with the DBPs, and interactions with the biomedical community, our goal is to help scientists to work more effectively in the e-science paradigm, enhancing experiment design, experiment execution, data analysis, information synthesis, hypothesis generation and testing, and understand human disease.

We show that the intersection of the class of 2-REA degrees with that of the ω-r.e. degrees consists precisely of the class of d.r.e. degrees. We also include some applications and show that there is no natural generalization of this result to higher levels of the REA hierarchy.

Given two incomparable c.e. Turing degrees a and b, we show that there exists a c.e. degree c such that c = (a ⋃ c) ⋂ (b ⋃ c), a ⋃ c | b ⋃ c, and c < a ⋃ b.

The present study aimed to develop effective moral educational interventions based on social psychology by using stories of moral exemplars. We tested whether motivation to engage in voluntary service as a form of moral behavior was better promoted by attainable and relevant exemplars or by unattainable and irrelevant exemplars. First, experiment 1, conducted in a lab, showed that stories of attainable exemplars more effectively promoted voluntary service activity engagement among undergraduate students compared with stories of unattainable exemplars and non-moral stories. (...) Second, experiment 2, a middle school classroom-level experiment with a quasi-experimental design, demonstrated that peer exemplars, who are perceived to be attainable and relevant to students, better promoted service engagement compared with historic figures in moral education classes.

The value of any kind of data is greatly enhanced when it exists in a form that allows it to be integrated with other data. One approach to integration is through the annotation of multiple bodies of data using common controlled vocabularies or ‘ontologies’. Unfortunately, the very success of this approach has led to a proliferation of ontologies which itself creates obstacles to integration. The Open Biomedical Ontologies (OBO) consortium has set in train a strategy to overcome this problem. Existing (...) OBO ontologies, including the Gene Ontology, are undergoing a process of coordinated reform and new ontologies being created on the basis of an evolving set of shared principles governing ontology development. The result is an expanding family of ontologies designed to be interoperable, logically well-formed, and to incorporate accurate representations of biological reality. We describe the OBO Foundry initiative, and provide guidelines for those who might wish to become involved. (shrink)

Righteous Indignation explores the philosophy of Christian anger—for example what anger is, what it means for God to be angry, and when anger is morally appropriate. The contributors examine several dimensions of the topic, including divine wrath, imprecatory psalms, and the proper place of anger in the life of Christians today.

Important features of the self-concept can be located outside of the individual and inside close or related others. The authors use this insight to reinterpret data previously said to support the empathy-altruism model of helping, which asserts that empathic concern for another results in selflessness and true altruism. That is, they argue that the conditions that lead to empathic concern also lead to a greater sense of self-other overlap, raising the possibility that helping under these conditions is not selfless but (...) is also directed toward the self. In 3 studies, the impact of empathic concern on willingness to help was eliminated when oneness--a measure of perceived self-other overlap--was considered. Path analyses revealed further that empathic concern increased helping only through its relation to perceived oneness, thereby throwing the empathy-altruism model into question. The authors suggest that empathic concern affects helping primarily as an emotional signal of oneness. (shrink)

The Politics of the Soul: Eric Voegelin on Religious Experience includes eight essays examining one of the most profound studies of religious experience to appear in the last century: that of the political philosopher Eric Voegelin. Voegelin is increasingly recognized as a political theorist of exceptional scope and erudition and the most important philosopher of his time since Toynbee, and his treatment of religious experience is a crucial part of his overall analysis of existence and history. This collection of essays (...) by prominenet Voegelin scholars is the first book to explore the relevance of that analysis to the contemporary understanding of political theory, theology, history, and philosophy of consciousness, and as such it constitutes a significant contribution not only to Voegelin scholarship but to the current quest for theoretical foundations.

ABSTRACT BACKGROUND: The objective of this study was to identify factors motivating women to take part in endometriosis research and to determine if these factors differ for women participating in clinical versus basic science studies. METHODS: A consecutive series of 24 women volunteering for participation in endometriosis‐related research were asked to indicate, in their own words, why they chose to volunteer. In addition, the women were asked to rate, on a scale of 0 to 10, sixteen potentially motivating factors. The (...) information was gathered in the form of an anonymous self‐administered questionnaire. RESULTS: Strong motivating factors (mean score >8) included potential benefit to other women's health, improvement to one's own condition, and participation in scientific advancement. Weak motivating factors (mean score <3) included financial compensation, making one's doctor happy, and use of ‘natural’ products. No difference was detected between clinical and basic science study participants. CONCLUSION: This study is the first study to specifically investigate the factors that motivate women to take part in endometriosis research. Understanding why women choose to take part in such research is important to the integrity of the informed consent process. The factors most strongly motivating women to participate in endometriosis research related to improving personal or public health; the weakest, to financial compensation and pleasing the doctor.

Alongside concerns for animal welfare, concerns for land, water, and climate are undermining established food identities in many parts of the world. In Aotearoa New Zealand, agrifood relations are bound tightly into national identities and the materialities of export dependence on dairying and agriculture more widely. Dairy/ing identities have been central to national development projects and the politics that underpin them for much of New Zealand’s history. They are central to an intransigent agrifood political ontology. For the last decade, however, (...) they have been challenged by the identity politics of ethical food consumption. This paper explores the ensuing contests and asks how they are reshaping agrifood identities. We draw on interviews with 15 participants in Aotearoa New Zealand who have made dietary transitions that reduce or exclude dairy products. Our aim is not to identify a new post-dairying identity or claim a reconfigured national identity, but to examine the collision of production-consumption values in the context of a dominant place-based food identity. We ask how participants navigate contradictory commitments to becoming ‘good environmental citizens’ whilst remaining ‘good national citizens’. The paper offers insights for examining similar struggles elsewhere and the potential to shift agrifood relations and undermine entrenched political ontologies through ethical food consumption values.

We provide a retrospective of 25 years of the International Conference on AI and Law, which was first held in 1987. Fifty papers have been selected from the thirteen conferences and each of them is described in a short subsection individually written by one of the 24 authors. These subsections attempt to place the paper discussed in the context of the development of AI and Law, while often offering some personal reactions and reflections. As a whole, the subsections build into (...) a history of the last quarter century of the field, and provide some insights into where it has come from, where it is now, and where it might go.

Two articles by Lewis Feuer caught my attention in the '40s when 1 was wondering, asa student physicist, about the relations of physics to philosophy and to the world in turmoil. One was his essay on 'The Development of Logical Empiricism' (1941), and the other his critical review of Philipp Frank's biography of Einstein, 'Philosophy and the Theory of Relativity' (1947). How extraordinary it was to find so intelligent, independent, critical, and humane a mind; and furthermore he went further, (...) as I soon realized when I looked for his name on other publications. I recall arguing with myself over his exploration of 'Indeterminacy and Economic Development' (1948), and even more when I read his 'Dialectical Materialism and Soviet Science' (1949). More papers, and then the fascinating, sometimes irritating, always insightful, books. His monograph on Psychoanalysis and Ethics 1955, the beautiful sociological and humanist study of Spinoza and the Rise of Liberalism (1958), his essays on 'The Social Roots of Einstein's Theory of Relativity' (1971) together with the book on Einstein and the Genera tions of Science (1974), the splendid reader from the works of Marx and Engels, Basic Writings on Politics and Philosophy (1959) which was a major text of the '60s, the stimulating essays on the social formation which seems to have been required for a modern scientific movement to develop, set forth most convincingly in The Scientific Intellectual (1963).

Court D. Lewis, author of Repentance and the Right to Forgiveness, presents a rights-based theory of ethics grounded in eirenéism, a needs-based theory of rights (inspired by Nicholas Wolterstorff) that seeks peaceful flourishing for all moral agents. This approach creates a moral relationship between victims and wrongdoers such that wrongdoers owe victims compensatory obligations. However, one further result is that wrongdoers may be owed forgiveness by victims. This leads to the “repugnant implication” that victims may be wrongdoers who do (...) not forgive. Author Lewis addresses the “repugnant implication” by showing that victims are obligated to work toward forgiveness, if not forgiveness itself. Critic Gregory L. Bock argues that victims are not the only ones who can forgive, that the personal dimensions of forgiveness are overlooked, and that the force of the “repugnancy implication” may be questioned. Instead of rights-based eirenéism, Bock supports a virtue ethics framework. Instead of rights-based eirenéism, Bock encourages virtue ethics. Critic David Boersema raises questions about the binding nature of relationships, the dependency of flourishing upon forgiveness, and the nature of needs or rights. Boersema also questions the wisdom of a rights-based approach to forgiveness. Critic Jennifer Kling asks whether a rights-based approach is necessary to ground obligations to meet the needs of others: why not an ethics of care? If a rights-based approach is taken, perhaps a wrongdoer is obligated to not make forgiveness a life good. By disengaging this obligation, we avoid constraining a victim’s work toward forgiveness, especially when the wrongdoing is oppressive. Author Lewis responds to these objections. (shrink)

Given a set of objects characterized by a number of attributes, hidden patterns can be discovered in them for the grouping of similar objects into clusters. If each of these clusters can be considered as exemplifying a certain concept, then the problem concerned can be referred to as a concept discovery problem. This concept discovery problem can be solved to some extent by existing data clustering techniques. However, they may not be applicable when the concept involved is vague in nature (...) or when the attributes characterizing the objects can be qualitative, quantitative, and fuzzy at the same time. To discover such concepts from objects with such characteristics, we propose a Genetic-Algorithm-based technique. By encoding a specific object grouping in a chromosome and a fitness measure to evaluate the cluster quality, the proposed technique is able to discover meaningful fuzzy clusters and assign membership degrees to objects that do not fully exemplify a certain concept. For evaluation, we tested the proposed technique with simulated and real data and the results are found to be very promising. (shrink)
