Two different models for chemical bond were developed almost simultaneously after the Schrödinger formulation of quantum theory. These are known as the valence bond (VB) and molecular orbital (MO) theories. Initially chemists preferred the VB theory and ignored the MO theory. Now the VB theory is almost dropped out of currency. The context of discovery and Linus Pauling’s overpowering influence gave the VB theory its initial advantage. The current universal acceptance of the MO theory is due to its ability to (...) provide direct interpretation of many different types of experiments now being pursued. In current research both localized bonds and delocalized charge distributions play important roles and the MO theory has been successful in giving a good account of both. (shrink)

In this article I intend to describe an issue of the Dutch euthanasia practice that is not common knowledge. After some general introductory descriptions, by way of formulating a frame of reference, I shall describe the effects of this practice on patients, physicians and families, followed by a more philosophical reflection on the significance of these effects for the assessment of the authenticity of a request and the nature of unbearable suffering, two key concepts in the procedure towards euthanasia or (...) physician-assisted suicide. This article does not focus on the arguments for or against euthanasia and the ethical justification of physician-assisted dying. These arguments have been described extensively in Kimsma and Van Leeuwen (Asking to die. Inside the Dutch debate about euthanasia, Kluwer Academic Publishers, Dordrecht, 1998). (shrink)

Dutch developments on euthanasia have drawn much attention over the years. Defenders and opponents have been telling very different stories about the practice of euthanasia and the frequency of cases, and the Dutch government has been struggling with the legal and moral problems involved. Concern about the procedures followed by physicians as well as questions on the “real” figures led the government to decide to organize an epidemiological study on the extent and the decision making. The results of the study (...) were published in November 1991. Interpretation of the data may lead to a final settlement of the debate on euthanasia and has inevitably led to a revival of the moral debate of the 1970s. For the moment it has been decided that euthanasia will remain officially illegal under the Penal Code. However, in cases where euthanasia does occur, Attorneys General will continue to check the procedures followed by physicians to ensure no abuses have occurred and to safeguard physicians against prosecution. In this contribution, we discuss the development and intertwinement of legal, medical, and moral aspects of euthanasia in The Netherlands and the effects of the empirical studies of 1991, both on definitions and procedures for medical decisions at the end of life.

One of the areas of concern raised by cross-border reproductive travel regards the treatment of women who are solicited to provide their ova or surrogacy services to foreign consumers. This is particularly troublesome in the context of developing countries where endemic poverty and low standards for both medical care and informed consent may place these women at risk of exploitation and harm. We explore two contrasting proposals for policy development regarding the industry, both of which seek to promote ethical outcomes (...) and social justice: While one proposal advocates efforts to minimize cross-border demand for female reproductive resources through the pursuit of national self-sufficiency, the other defends cross-border trade as a means for meeting the needs of vulnerable groups. Despite the conflicting objectives of the proposed strategies, the paper identifies common values and points of agreement between the two, including the importance of regulations to safeguard those providing ova or surrogacy services.

This paper examines conceptual issues that arise in applications of Darwinian natural selection to cultural systems. I argue that many criticisms of cultural selectionist models have been based on an over-detailed reading of the analogy between biological and cultural units of selection. I identify five of the most powerful objections to cultural selection theory and argue that none cuts to its heart. Some objections are based on mistaken assumptions about the simplicity of the mechanisms of biological heredity. Other objections are (...) attributable, rather, to mistaken inferences from observations of biological subject matter to what is essential in natural selection. I argue that such features are idiosyncratic of biological systems, but not essential for natural selection. My arguments throughout are illustrated by examples from biological and cultural evolution, and counter-factual illustrations from the history of theoretical biology. Introduction Cultural Selection Theory First Objection: Lamarckianism Second Objection: Genotype–Phenotype Distinction Third Objection: Common Hereditary Architecture Fourth Objection: Biological Analogue for Cultural Units 6.1 Regarding strict analogues 6.2 Regarding the trait analogue 6.3 Regarding the virus analogue Fifth Objection: Environmental Interaction Conclusion CiteULike Connotea Del.icio.us What's this?

Context Physicians are regularly confronted with research that is funded or presented by industry. Objective To assess whether physicians discount for conflicts of interest when weighing evidence for prescribing a new drug. Design and setting Participants were presented with an abstract from a single clinical trial finding positive results for a fictitious new drug. Physicians were randomly assigned one version of a hypothetical scenario, which varied on conflict of interest: ‘presenter conflict’, ‘researcher conflict’ and ‘no conflict’. Participants 515 randomly selected (...) Fellows in the American College of Obstetricians and Gynecologists' Collaborative Ambulatory Research Network; 253 surveys (49%) were returned. Main object measures The self-reported likelihood that physicians would prescribe the new drug as a first-line therapy. Results Physicians do not significantly discount for conflicts of interest in their self-reported likelihood of prescribing the new drug after reading the single abstract and scenario. However, when asked explicitly to compare conflict and no conflict, 69% report that they would discount for researcher conflict and 57% report that they would discount for presenter conflict. When asked to guess how favourable the results of this study were towards the new drug, compared with the other trials published so far, their perceptions were not significantly influenced by conflict of interest information. Conclusion While physicians believe that they should discount the value of information from conflicted sources, they did not do so in the absence of a direct comparison between two studies. This brings into question the effectiveness of merely disclosing the funding sources of published studies. (shrink)

We argue that the ecological research community should develop a plan for improving the ethical consistency and moral robustness of the field. We propose a particular ethics strategy—specifically, an ongoing process of collective ethical reflection that the community of ecological researchers, with the cooperation of applied ethicists and philosophers of biology, can use to address the needs we identify. We suggest a particular set of conceptual and analytic tools that, we argue, collectively have the resources to provide an empirically grounded (...) and conceptually complete foundation for an ethics strategy for ecological research. We illustrate our argument with information gathered from a survey of ecologists conducted at the 2013 meeting of the Canadian Society of Ecology and Evolution. (shrink)

Medical decisions regarding end-of-life care have undergone significant changes in recent decades, driven by changes in both medicine and society. Catholic tradition in medical ethics offers clear guidance in many issues, and a moral framework accessible to those who do not share the same faith as well as to members of its faith community. In some areas, a Catholic perspective can be seen clearly and confidently, such as in teachings on the permissibility of suicide and euthanasia. In others, such as (...) withdrawal of nutrition and hydration, the Church does not yet speak with one voice and has not closed out the discussion. Yet, it is not in the teaching on individual issues that a Catholic moral tradition offers the most help and comfort, but in its account of what it means to lead a life in Christ, and to prepare for a Christian death. As in the problem of pain and suffering, it is the spiritual support more than the ethical guidance that helps both patients and physicians bear the unbearable and fathom the unfathomable. (shrink)

In the current global care regime, care shortages in wealthy nations such as the United States, Canada, Italy, and Hong Kong are being addressed through the global supply of cheap migrant care labor from less wealthy nations. This paper argues that Feminist Care Ethics has a great deal to offer in the analysis of this global care regime. Joan Tronto's own critiques of the migration of care workers have focused on analogies between workers and imported slaves: both are intrinsically exploited, (...) vulnerable, excluded, and stigmatized. She argues that this situation undermines human virtue and the possibility of adequate care, and she advocates instead a model wherein caregiving is seen as a basis for .. (shrink)

International medical travel occurs when patients cross national borders to purchase medical goods and services. On occasion, physicians in home countries will be the last point of domestic contact for patients seeking healthcare information before they travel abroad for care. When this is the case, physicians have a unique opportunity to inform patients about their options and help guide them towards ethical practices. This opportunity brings to the fore an important question: What role should physicians in more-developed home countries play (...) in promoting or constraining international medical travel towards less-developed destination countries? In our view, critical attention to the decision spaces of patients—defined by the personal circumstances, socio-cultural cues, and legal constraints that inform decision-making—is a useful starting point for evaluating the proper response of physicians to various forms of international medical travel.

Drawing on conceptual tools from philosophical bioethics, economics, and materialist feminism, we advocate viewing transnational commercial surrogacy as labor and consider what it means to compensate women for this work. We find two distinct but interrelated concerns emerge in our discussion of wages for surrogates: how to value and compensate for social reproduction, and how to establish a fair wage for surrogates. We explore limitations of minimum wage policy in addressing the undervaluation of biological and emotional labor in the transnational (...) commercial surrogacy industry. We argue that subsidization is a superior method of addressing at least one cause of undervaluation. (shrink)

In his talk about G.K.'s Weekly to the 1986 Toronto Conference, Father Brocard Sewell, O. Carm., spoke about Chesterton's tribute to Alderman Cedric Chivers. This tribute was written at the time of Cedric Chivers's death and was published in G.K.'s Weekly . Cedric Chivers was, for many years, the Major of Bath, a bookbinder, and one of the Directors of G.K.'s Weekly. He was one of Chesterton's close friends.

Hegel and Plato offer distinctive but related philosophical accounts of ethical absolutism, thereby suggesting that a comparative study of their ethical ideas will be valuable in clarifying their respective philosophical approaches, as well as in admitting a critical examination of the structure for and viability of two significant absolutist ethical standpoints. This paper will concentrate on evaluating their rival conceptions of the Good and related ethical doctrines as specific responses to their recognition of the need to secure ethical life against (...) the socially divisive effects of ethical controversy. This common inspiration of their ethical theorizing confirms the validity and significance of Williams' remarks on the significance of the consciousness of ethical variation cited earlier. Plato's and Hegel's elaborations of absolutist ethical positions, however, conflict with Williams' scepticism over whether there is an objective basis for ethics which is invoked in his Ethics and the Limits of Philosophy and his paper �The Truth in Relativism� to justify relativism, at least in regard to significantly divergent and diachronically distinct ethical practices. Ultimately, this paper will consider the extent to which the absolutist aspirations of Plato's and Hegel's ethical theories can be sustained in the light of the evident variation in ethical thought and practice.

In the history of Russian philosophy, V. S. Solovyov is known as one of the prominent spokesmen of theological idealism. Lenin more than once pointed to the need to combat the ideas of this philosopher . He quite properly regarded them as the theoretical foundation of the ideology of "liberal renegacy.".

Corruption involves greed, money, and risky decision-making. We explore the love of money, pay satisfaction, probability of risk, and dishonesty across cultures. Avaricious monetary aspiration breeds unethicality. Prospect theory frames decisions in the gains-losses domain and high-low probability. Pay dissatisfaction (in the losses domain) incites dishonesty in the name of justice at the individual level. The Corruption Perceptions Index, CPI, signals a high-low probability of getting caught for dishonesty at the country level. We theorize that decision-makers adopt avaricious love-of-money aspiration (...) as a lens and frame dishonesty in the gains-losses domain (pay satisfaction-dissatisfaction, Level 1) and high-low probability (CPI, Level 2) to maximize expected utility and ultimate serenity. We challenge the myth: Pay satisfaction mitigates dishonesty across nations consistently. Based on 6500 managers in 32 countries, our cross-level three-dimensional visualization offers the following discoveries. Under high aspiration conditions, pay dissatisfaction excites the highest- (third-highest) avaricious justice-seeking dishonesty in high (medium) CPI nations, supporting the certainty effect. However, pay satisfaction provokes the second-highest avaricious opportunity-seizing dishonesty in low CPI entities, sustaining the possibility effect—maximizing expected utility. Under low aspiration conditions, high pay satisfaction consistently leads to low dishonesty, demonstrating risk aversion—achieving ultimate serenity. We expand prospect theory from a micro and individual-level theory to a cross-level theory of monetary wisdom across 32 nations. We enhance the S-shaped Curve to three 3-D corruption surfaces across three levels of the global economic pyramid, providing novel insights into behavioral economics, business ethics, the environment, and responsibility.

Feminist Care Ethics has much to offer in an analysis of the international migration of care workers. This paper argues, however, that Joan Tronto’s analysis of this international care regime is incomplete insofar as it overlooks the ways in which the current global care market is progressive for the workers and the significant harms this market is inflicting on care receivers in source countries. In order for Feminist Care Ethics to fulfill its potential, it must be developed beyond a visionary (...) tool for revaluing care—it must also produce analytic tools for evaluating real alternatives under pressing, real-time constraints.
