In The Ethics of Food, Gregory E. Pence brings together a collection of voices who share the view that the ethics of genetically modified food is among the most pressing societal questions of our time. This comprehensive collection addresses a broad range of subjects, including the meaning of food, moral analyses of vegetarianism and starvation, the safety and environmental risks of genetically modified food, issues of global food politics and the food industry, and the relationships among food, evolution, and human (...) history.

Critics of marcus singer's deduction of the generalization argument from the principle of consequences and the generalization principle ("generalization in ethics," page 66) insist that his use of "everyone" in that deduction is ambiguous, I.E., "everyone" is used both collectively and distributively, And that the deduction is invalid. In this paper, I provide a valid deduction of the generalization argument from those premises which avoids this difficulty entirely. I argue that the conclusion so deduced is logically and morally equivalent to (...) singer's. (shrink)

While many books exist on the subject of war, few scholars have offered historical and practical analyses of nonviolent alternatives to the military defense of nations.

Leading scholars examine the relation between Irigaray’s early writings and her later, more political work.

The way of wisdom is revealed to be the journey of life with wisdom as our guide, a mode of traveling through life which Yahweh approves, the foundational order of all creation and more.

Indonesia has received Islam over the past millennium During this period, Islam has intermingled in varying degrees with Buddhism, Hinduism, and indigenous animism in different parts of the archipelago. Consequently, beliefs and practices diverge. Nevertheless, Islam has an overwhelming if diverse presence in Indonesia. The paper will examine the resultant diverse versions of Islam that currently coexist in Indonesia. These versions are the modernist, traditional, devotional, and syncretic aspects of Islam. Each version will be analyzed in terms of both differences (...) and similarities. (shrink)

The hippocampal formation is a structure critical to navigation and many forms of memory. In mammals, the firing of place cells is widely regarded as the fundamental unit of HF information processing. Supporting homology between the avian and mammalian HF, context-specific patterns of Egr1 have been reported in birds that are comparable to those produced by place cell firing in mammals. Recent electrophysiological data, however, suggest that many avian species lack place cells, potentially undermining the correspondence between Egr1 and place (...) cell-related firing in the avian brain. To clarify this, the current study examines Egr1 expression in Japanese quail under conditions known to elicit only weakly spatially modulated firing patterns and report robust context-dependent Egr1 expression. These data confirm that context-dependent expression of Egr1 is not dependent on precise place fields and provide insight into how these birds are able to perform complex spatial tasks despite lacking mammalian-like place cells.

This response (a) integrates non-equilibrium evolutionary genetic models, such as coevolutionary arms-races and recent selective sweeps, into a framework for understanding common, harmful, heritable mental disorders; (b) discusses the forms of ancestral neutrality or balancing selection that may explain some portion of mental disorder risk; and (c) emphasizes that normally functioning psychological adaptations work against a backdrop of mutational and environmental noise.

Deception is a useful methodological device for studying attitudes and behavior, but deceptive studies fail to fulfill the informed consent requirements in the U.S. federal regulations. This means that before they can be approved by Institutional Review Boards, they must satisfy the four regulatory conditions for a waiver or alteration of these requirements. To illustrate our interpretation, we apply the conditions to a recent study that used deception to show that subjects judged the same wine as more enjoyable when they (...) believed it had a higher price.

In The Healer's Power, Howard Brody placed the concept of power at the heart of medicine's moral discourse. Struck by the absence of “power” in the prevailing vocabulary of medical ethics, yet aware of peripheral allusions to power in the writings of some medical ethicists, he intuited the importance of power from the silence surrounding it. He formulated the problem of the healer's power and its responsible use as “the central ethical problem in medicine.” Through the prism of power he (...) refracted a wide range of ethical problems, from informed consent to truth-telling, from confidentiality to futility, from the physician's fantasies to the physician's virtues. At times this prism shed new light on old problems, enabling us to see from an unexpected angle the elements of which the problem was composed. At other times it exposed issues of ethical significance that had been neglected in the bioethics literature. (shrink)

The fearful ape hypothesis proposes that heightened fearfulness in humans is adaptive. However, despite its attractive anthropocentric narrative, the evidence presented for greater fearfulness in humans versus other apes is not sufficient to support this claim. Conceptualization, context, and comparison are strongly lacking in Grossmann's proposal, but are key to understanding variation in the fear response among individuals and species.

Using payment to recruit research subjects is a common practice, but it raises ethical concerns that coercion or undue inducement could potentially compromise participants’ informed consent. This is the first national study to explore the attitudes of IRB members and other human subjects protection professionals concerning whether payment of research participants constitutes coercion or undue influence, and if so, why. The majority of respondents expressed concern that payment of any amount might influence a participant’s decisions or behaviors regarding research participation. (...) Respondents expressed greater acceptance of payment as reimbursement or compensation than as an incentive to participate in research, and most agreed that subjects are coerced if the offer of payment makes them participate when they otherwise would not or when the offer of payment causes them to feel that they have no reasonable alternative but to participate . Views about undue influence were similar. We conclude that human subjects protection professionals hold expansive and inconsistent views about coercion and undue influence that may interfere with the recruitment of research participants and impede valuable research.

Given that natural selection is so powerful at optimizing complex adaptations, why does it seem unable to eliminate genes (susceptibility alleles) that predispose to common, harmful, heritable mental disorders, such as schizophrenia or bipolar disorder? We assess three leading explanations for this apparent paradox from evolutionary genetic theory: (1) ancestral neutrality (susceptibility alleles were not harmful among ancestors), (2) balancing selection (susceptibility alleles sometimes increased fitness), and (3) polygenic mutation-selection balance (mental disorders reflect the inevitable mutational load on the thousands (...) of genes underlying human behavior). The first two explanations are commonly assumed in psychiatric genetics and Darwinian psychiatry, while mutation-selection has often been discounted. All three models can explain persistent genetic variance in some traits under some conditions, but the first two have serious problems in explaining human mental disorders. Ancestral neutrality fails to explain low mental disorder frequencies and requires implausibly small selection coefficients against mental disorders given the data on the reproductive costs and impairment of mental disorders. Balancing selection (including spatio-temporal variation in selection, heterozygote advantage, antagonistic pleiotropy, and frequency-dependent selection) tends to favor environmentally contingent adaptations (which would show no heritability) or high-frequency alleles (which psychiatric genetics would have already found). Only polygenic mutation-selection balance seems consistent with the data on mental disorder prevalence rates, fitness costs, the likely rarity of susceptibility alleles, and the increased risks of mental disorders with brain trauma, inbreeding, and paternal age. This evolutionary genetic framework for mental disorders has wide-ranging implications for psychology, psychiatry, behavior genetics, molecular genetics, and evolutionary approaches to studying human behavior.

Christian health care professionals in our secular and pluralistic society often face uncertainty about the place religious faith holds in today's medical practice. Through an examination of a virtue-based ethics, this book proposes a theological view of medical ethics that helps the Christian physician reconcile faith, reason, and professional duty. Edmund D. Pellegrino and David C. Thomasma trace the history of virtue in moral thought, and they examine current debate about a virtue ethic's place in contemporary bioethics. Their proposal balances (...) theological ethics, based on the virtues of faith, hope, and charity, with contemporary medical ethics, based on the principles of beneficence, justice, and autonomy. The result is a theory of clinical ethics that centers on the virtue of charity and is manifest in practical moral decisions. Using Christian bioethical principles, the authors address today's divisive issues in medicine. For health care providers and all those involved in the fields of ethics and religion, this volume shows how faith and reason can combine to create the best possible healing relationship between health care professional and patient.

Mood disorders, including major depressive disorder and bipolar disorder, are highly prevalent, frequently disabling, and sometimes deadly. Additional research and more effective medications are desperately needed, but clinical trials research in mood disorders is fraught with ethical issues. Although many authors have discussed these issues, most do so from a theoretical viewpoint. This manuscript uses available empirical data to inform a discussion of the primary ethical issues raised in mood disorders research. These include issues of consent and decision-making capacity, including (...) patients’ motivations for participating in research. We also address drug withdrawals, placebo controls, and the overall safety of research. Finally, we examine the extant literature for studies discussing potential indirect benefits of clinical trials research to participants. Taken together, the evidence suggests that clinical trials research incorporating drug withdrawals and placebo controls can be conducted safely and ethically, even in patients with severe or treatment-resistant mood disorders. In fact, given the dearth of effective treatment options for this population, it is our opinion that a moral imperative exists to extend the offer of research participation to severely ill or treatment-resistant groups.

While across the animal kingdom offspring are born smaller than their parents, notable exceptions exist. Several dipteran species belonging to the Hippoboscoidea superfamily can produce offspring larger than themselves. In this essay, the blood‐feeding tsetse is focused on. It is suggested that the extreme reproductive strategy of this fly is enabled by feeding solely on highly nutritious blood, and producing larval offspring that are soft and malleable. This immense reproductive expenditure may have evolved to avoid competition with other biting flies. (...) Tsetse also transmit blood‐borne parasites that cause the fatal diseases called African trypanosomiases. It is discussed how tsetse life history and reproductive strategy profoundly influence the type of vector control interventions used to reduce fly populations. In closing, it is argued that the unusual life history of tsetse warrants their preservation in the areas where human and animal health is not threatened. (shrink)

lecting statistics about missing bindings and macros, and other errors. This guides debugging and development efforts, leading to iterative improvements in both the tools and the quality of the converted corpus. The build system thus serves as both a production conversion engine and software test harness. We have now processed the complete arχiv collection through 2006 consisting of more than 400,000 documents (a complete run is a processor-yearsize undertaking), continuously improving our success rate. We are now able to convert more (...) than 90% of these documents to XHTML+MathML. We consider over 60% to be successes, converted with no or minor warnings. While the remaining 30% can also be converted, their quality is doubtful, due to unsupported macros or conversion errors. (shrink)
