Phillips & Silverstein's ambitious link between receptor abnormalities and the symptoms of schizophrenia involves a certain amount of fuzziness: No detailed mechanism is suggested through which the proposed abnormality would lead to psychological traits. We propose that detailed simulation of brain regions, using model neural networks, can aid in understanding the relation between biological abnormality and psychological dysfunction in schizophrenia.

The basic reproduction ratio, R0, is a fundamental concept in epidemiology. It is defined as the total number of secondary infections brought on by a single primary infection, in a totally susceptible population. The value of R0 indicates whether a starting epidemic reaches a considerable part of the population and causes a lot of damage, or whether it remains restricted to a relatively small number of individuals. To calculate R0 one has to evaluate an integral that ranges over the duration (...) of the infection of the host. This duration is, of course, limited by remaining host longevity. So, R0 depends on remaining host longevity and in this paper we show that for long-lived hosts this aspect may not be ignored for long-lasting infections. We investigate in particular how this epidemiological measure of pathogen fitness depends on host longevity. For our analyses we adopt and combine a generic within- and between-host model from the literature. To find the optimal strategy for a pathogen from an evolutionary point of view, we focus on the indicator $$R_0^{{opt}}$$, i.e., the optimum of R0 as a function of its replication and mutation rates. These are the within-host parameters that the pathogen has at its disposal to optimize its strategy. We show that $$R_0^{{opt}}$$ is highly influenced by remaining host longevity in combination with the contact rate between hosts in a susceptible population. In addition, these two parameters determine whether a killer-like or a milker-like strategy is optimal for a given pathogen. In the killer-like strategy the pathogen has a high rate of reproduction within the host in a short time span causing a relatively short disease, whereas in the milker-like strategy the pathogen multiplies relatively slowly, producing a continuous small amount of offspring over time with a small effect on host health. The present research allows for the determination of a bifurcation line in the plane of host longevity versus contact rate that forms the boundary between the milker-like and killer-like regions. This plot shows that for short remaining host longevities the killer-like strategy is optimal, whereas for very long remaining host longevities the milker-like strategy is advantageous. For in-between values of host longevity, the contact rate determines which of both strategies is optimal. (shrink)

We distinguish two types of cases that have potential to generate quasi-cyclical preferences: self-involving choices where an agent oscillates between first- and third-person perspectives that conflict regarding their life-changing implications, and self-serving choices where frame-based reasoning can be “first-personally rational” yet “third-personally irrational.” We argue that the distinction between these types of cases deserves more attention in Bermúdez's account.

Criticisms of the ethical justification of antidoping legislation are not uncommon in the literatures of medical ethics, sports ethics and sports medicine. Critics of antidoping point to inconsistencies of principle in the application of legislation and the unjustifiability of ethical postures enshrined in the World Anti-Doping Code, a new version of which came into effect in January 2009. This article explores the arguments concerning the apparent legal peculiarities of antidoping legislation and their ethically salient features in terms of: notions of (...) culpability, liability and guilt; aspects of potential duplication of punishments and the limitations of athlete privacy in antidoping practice and policy. It is noted that tensions still exist between legal and ethical principles and norms that require further critical attention. (shrink)

BackgroundLarge-scale, centralized data repositories are playing a critical and unprecedented role in fostering innovative health research, leading to new opportunities as well as dilemmas for the medical sciences. Uncovering the reasons as to why citizens do or do not contribute to such repositories, for example, to population-based biobanks, is therefore crucial. We investigated and compared the views of existing participants and non-participants on contributing to large-scale, centralized health research data repositories with those of ex-participants regarding the decision to end their (...) participation. This comparison could yield new insights into motives of participation and non-participation, in particular the behavioural change of withdrawal.MethodsWe conducted 36 in-depth interviews with ex-participants, participants, and non-participants of a three-generation, population-based biobank in the Netherlands. The interviews focused on the respondents’ decision-making processes relating to their participation in a large-scale, centralized repository for health research data.ResultsThe decision of participants and non-participants to contribute to the biobank was motivated by a desire to help others. Whereas participants perceived only benefits relating to their participation and were unconcerned about potential risks, non-participants and ex-participants raised concerns about the threat of large-scale, centralized public data repositories and public institutes, such as social exclusion or commercialization. Our analysis of ex-participants’ perceptions suggests that intrapersonal characteristics, such as levels of trust in society, participation conceived as a social norm, and basic societal values account for differences between participants and non-participants.ConclusionsOur findings indicate the fluidity of motives centring on helping others in decisions to participate in large-scale, centralized health research data repositories. Efforts to improve participation should focus on enhancing the trustworthiness of such data repositories and developing layered strategies for communication with participants and with the public. Accordingly, personalized approaches for recruiting participants and transmitting information along with appropriate regulatory frameworks are required, which have important implications for current data management and informed consent procedures.

Misattributed paternity or ‘false’ paternity is when a man is wrongly thought, by himself and possibly by others, to be the biological father of a child. Nowadays, because of the progression of genetics and genomics the possibility of finding misattributed paternity during familial genetic testing has increased. In contrast to other medical information, which pertains primarily to individuals, information obtained by genetic testing and/or pedigree analysis necessarily has implications for other biologically related members in the family. Disclosing or not a (...) misattributed paternity has a number of different biological and social consequences for the people involved. Such an issue presents important ethical and deontological challenges. The debate centres on whether or not to inform the family and, particularly, whom in the family, about the possibility that misattributed paternity might be discovered incidentally, and whether or not it is the duty of the healthcare professional to disclose the results and to whom. In this paper, we consider the different perspectives and reported problems, and analyse their cultural, ethical and legal dimensions. We compare the position of HCPs from an Italian and British point of view, particularly their role in genetic counselling. We discuss whether the Oviedo Convention of the Council of Europe can be seen as a basis for enriching the debate. (shrink)

Sont publiees dans ce volume les communications prononcees lors des Journees Henri Joly, les 25, 26 et 27 mars 1993 a Grenoble. On y trouvera ces reflexions que peut, aujourd'hui encore, susciter en nous l'Antiquite classique. Sur la jalousie ou l'existence de mondes multiples; mais egalement sur la guerre civile ou les consequences politiques du mepris des frontieres naturelles. Ce ne sont la qu'exemples parmi d'autres. Fideles a la curiosite philosophique d'Henri Joly, dont les travaux igonraient les barrieres disciplinaires, elles (...) debordent donc largement le champ etriot de l'histoire de la philosophie pour englober une reflexion sur la langue et la litterature grecques, l'historiographie et l'anthropologie.

We argue that the pratyabhijñā system of Kaśmir Śaivism holds an inconsistent position. On the one hand, the Pratyabhijñā regards Śiva as an impersonal mechanism and the universe, including persons, as not having agency; call this the Impersonal Component. On the other hand, it considers Śiva himself as a person, and individual persons as having agency sufficient to respond to Śiva; call this the Personal Component. We maintain that the Personal Component should be affirmed and the Impersonal Component rejected. The (...) Impersonal Component’s claim that Śiva is unaware of and unaffected by his manifestation should be rejected, and the doctrine of satkāryavāda should be modified. The universe is Śiva’s manifestation, in the first instance, but it also has a relative autonomy from him. Moreover, humans have agency and freedom. Their actions effect Śiva. He grows and develops in response to his manifestation. (shrink)

The sixteen essays in Gender Struggles address a wide range of issues in gender struggles, from the more familiar ones that, for the last thirty years, have been the mainstay of feminist scholarship, such as motherhood, beauty, and sexual violence, to new topics inspired by post-industrialization and multiculturalism, such as the welfare state, cyberspace, hate speech, and queer politics, and finally to topics that traditionally have not been seen as appropriate subjects for philosophizing, such as adoption, care work, and the (...) home.

Over the past decade, we have witnessed some early signs of progress in the battle against international bribery and corruption, a problem that throughout the history of commerce had previously been ignored. We present a model that we then use to assess progress in reducing bribery. The model components include both hard law and soft law legislation components and enforcement and compliance components. We begin by summarizing the literature that convincingly argues that bribery is an immoral and unethical practice and (...) that the economic harm it causes falls most heavily on those least able to absorb it. The next section summarizes the main provisions of anti-bribery legislation including the Foreign Corrupt Practices Act (FCPA), the Organization for Eco nomic Development's Convention on Combating Bribery of Foreign Officials in International Business Transactions, the United Nations Convention Against Corruption and the laws of selected countries. We conclude this section with a discussion of the "moral imperialism" argument for not imposing Western laws and values on other cultures. The next section focuses on the roles played by NGOs including Transparency International (TI), the World Economic Forum (WEF), and the International Chamber of Commerce. We review trends in enforcement and prosecution, including a review of the United States' enforcement processes, mechanisms for cross-border legal assistance, a discussion of the distinctive nature of FCPA cases, and an assessment of what the future holds for enforcement. The final section focuses on compliance processes for corporations aimed at reducing the risk of FCPA and related violations. This section also addresses the ethics of gift giving and "grease" payments. The article concludes with a summary and suggestions for further research. Throughout the article, we reference important bribery cases and include comments from several authorities who are on the front lines of the battle against international bribery. (shrink)

University human research ethics application procedures can be complicated and daunting, especially for international students unfamiliar with the process and the language. We conducted focus groups and interviews with four research higher degree and 21 Master’s coursework international students at an Australian university to gain their views on the human ethics application process. We found the most important influences on their experience were: the time it took to do an application; support from supervisors, peers and others; their own language skills; (...) and their lack of familiarity with research ethics procedures. To improve the experience of international students undertaking research involving human research ethics applications, we recommend universities provide guidance on institutional ethics review processes, concepts and terminology, with translations in a range of languages, together with guidance on how to conduct research ethically within and outside the students’ own countries. We also recommend curricula be developed to further students’ understanding of the importance of ethical research practice, and that these curricula be embedded in undergraduate and postgraduate degree programs and reflected in course learning outcomes.

This book's importance is derived from three sources: careful conceptualization of teacher induction from historical, methodological, and international perspectives; systematic reviews of research literature relevant to various aspects of teacher induction including its social, cultural, and political contexts, program components and forms, and the range of its effects; substantial empirical studies on the important issues of teacher induction with different kinds of methodologies that exemplify future directions and approaches to the research in teacher induction.

Post-Kantian German idealism is an important influence on such contemporary approaches to philosophy as phenomenology, existentialism, and pragmatism, and because of this Seidel has undertaken an investigation of the related notions of activity and ground as they appear and develop in Fichte, Schelling, and Hegel. Common to all three thinkers is an emphasis on activity as conscious, free, and functioning as the ground or source of meaning for being. Each thinker in his own way also accepts the notion of a (...) dialectical interaction between the self and the world in which subject and object reciprocally influence one another. (shrink)
