We describe and analyse how large herbivores strongly diminished a woody vegetation, dominated by the unpalatable shrub Sambucus nigra L. and changed it into grassland. Density of woody species and cover of vegetation were measured in 1996, 2002 and 2012 in the grazed Oostvaardersplassen. In 2002 and 2012 we also measured density and cover in an ungrazed control site. In 2002 we measured intensity of browsing and bark loss of Sambucus shrubs in the grazed and control sites. In (...) the grazed site the density of Sambucus and Salix spp. declined significantly between 1996 and 2012, and large areas changed into grassland. In the control site the density of Sambucus increased significantly during this period, the density of Salix spp. did not change, and the vegetation consisted of a mixture of woody species and a field layer dominated by tall herbs. In 2002 and 2012 the percentages of dead Sambucus shrubs were significantly higher in the grazed site than in the control site. In 2002 the percentages of twigs browsed and ring barked stems of Sambucus shrubs were significantly higher in the grazed site than in the control site. Our results show that debarking caused mature Sambucus shrubs to die, but that heavy browsing may have helped this process. Our results also point to a significant neighbour effect on the break down of Sambucus, suggesting that Aggregational Resistance and Associational Palatability were both active. Essential conditions for the break down of this woody vegetation were the presence of large herbivores, the low ratio between the areas of summer and winter feeding habitats and the competition amongst herbivores. Browsing may have been responsible for seedling death, as seedlings were found only in the control site and not on the old and newly established grasslands in the grazed site. (shrink)

In list-method directed forgetting, reexposure to forgotten List 1 items has been shown to reduce directed forgetting. proposed that reexposure to a few List 1 items only during a direct test of memory reinstates the entire List 1 episode. In the present experiments, part-list reexposure in the context of indirect as well as direct memory tests reduced directed forgetting. Directed forgetting was reduced when 50% or more of the items were reexposed, and was intact when only 25% were reexposed. Furthermore, (...) part-list reexposure appeared to reinstate only reexposed items-not the entire List 1 episode. (shrink)

In this paper we examine the case of Tay, the Microsoft AI chatbot that was launched in March, 2016. After less than 24 hours, Microsoft shut down the experiment because the chatbot was generating tweets that were judged to be inappropriate since they included racist, sexist, and anti-Semitic language. We contend that the case of Tay illustrates a problem with the very nature of learning software that interacts directly with the public, and the developer's role and responsibility associated with it. (...) We make the case that when LS interacts directly with people or indirectly via social media, the developer has additional ethical responsibilities beyond those of standard software. There is an additional burden of care. (shrink)

In an individualistic society and in the increasingly competitive business environment people do not seem inclined to forgive others their trespasses. One is more likely to choose to ignore the virtue of forgiveness as a way of handling personnel situations involving intense conflict or mild disagreements, favoring instead the negative feelings of resentment, anger, revenge or retaliation. Business people seem less concerned with growth in virtue and character; interestingly they allow their character and ultimately their work relationships to deteriorate because (...) they hold onto feelings of anger and resentment. Is there a place for forgiveness in our interpersonal relationships in general and in corporate life in particular? I believe there is. A study of the virtue of forgiveness shows that it is a misunderstood virtue, but one that deserves attention. In this article I will examine the virtue of forgiveness, defining what forgiveness is and is not, and will illustrate how it might be situated as an essential human resource management strategy.

Individuals make decisions under uncertainty every day based on incomplete information concerning the potential outcome of the choice or chance levels. The choices individuals make often deviate from the rational or mathematically objective solution. Accordingly, the dynamics of human decision-making are difficult to capture using conventional, linear mathematical models. Here, we present data from a two-choice task with variable risk between sure loss and risky loss to illustrate how a simple nonlinear dynamical system can be employed to capture the dynamics (...) of human decision-making under uncertainty (i.e., multi-stability, bifurcations). We test the feasibility of this model quantitatively and demonstrate how the model can account for up to 86% of the observed choice behavior. The implications of using dynamical models for explaining the nonlinear complexities of human decision-making are discussed, as well as the degree to which nonlinear dynamical systems theory might offer an alternative framework for understanding human decision-making processes.

Protection of human participants is a fundamental facet of biomedical research. We report the activities of a health service research study in which there were three institutional review boards (IRBs), three legal departments and one research administration department providing recommendations and mandating changes in the study methods. Complying with IRB requirements can be challenging, but can also adversely affect study outcomes. Multiple protocol changes mandated from multiple IRBs created a research method that was not reflective of how substance use screening (...) would be performed in a clinical setting. There was direct conflict between the IRBs' perceptions of participants' protection with the researchers' need to use research methodology that assures the clinical relevancy of results. (shrink)

Esprit, l’un des mots clés des Pensées, reçoit chez Pascal deux significations : la raison et le souffle intérieur. Si l’esprit en tant que mens rationalis appartient au deuxième ordre, l’esprit en tant que mens spiritualis relève du troisième ordre. Deux dualismes se croisent dans la distinction pascalienne des trois ordres : le premier de nature philosophique, cartésienne, oppose le premier ordre, voué au corps, et les deuxième et troisième ordres, voués à la mens ; le second, de nature éthico-religieuse, (...) oppose le premier et le deuxième ordres, ordres de la cupidité, au troisième ordre, celui de la charité. Au-dessus de l’esprit/raison se tient l’esprit/amour. Pascal tisse, au sein du troisième ordre, un lien entre l’esprit et le cœur. Dans la notion de spiritus cordialis, d’esprit cordial, se situe l’apport essentiel de l’auteur des Pensées.« Esprit », one of the key-words of Pascal’s Pensées, has two meanings according to Pascal : i.e. reason and interior creative inspiration. If esprit as mens rationalis belongs to the second order, esprit as mens spiritualis refers to the third order. Two dualisms cross themselves within the Pascalian distinction of three orders. The former – of a philosophical nature, i.e. Cartesian – opposes the first order, devoted to the body and the second and third order devoted to the mens ; the latter – of an ethico-religious nature – opposes both the first and second order, i.e. the orders of cupidity to the third order, i.e. that of charity. The esprit as love rests above the esprit as reason. Pascal weaves, amid the third order a link between the esprit and the heart. The major contribution of the author of the Pensées rests in the concept of spiritus cordialis. (shrink)

Health care reform poses numerous challenges. A core challenge is to make health care more efficient and effective without causing more harm than benefit. Additionally, those fashioning health-care policy must encourage patients to exercise caution and restraint when expending scarce resources; restrict the ability of politicians to advance their careers by promising alluring but costly entitlements, many of which they will not be able to deliver; face the demographic challenges of an aging population; and avoid regulations that create significant inefficiencies (...) and restrict access to health care. Given such real-world challenges, how should health care be reformed in the United States or elsewhere? This number of The Journal of Medicine and Philosophy examines many of the complex issues that must be considered in reforming a health-care system. (shrink)

This paper considers the problem that arises when the number of patients who need a resource exceeds the supply. An initial decision-making model is proposed that uses two essential criteria, medical prognosis and the priority of life-threatening situations. The model is then subjected to the criticism that it is grotesque to ignore questions relating to the value of, for example, a productive mother over against an aged recluse, and to treat them as having equal rights to access. It is argued (...) that this criticism need not be an expression of prejudice but may reflect a defendable view in which utilitarian considerations enter into the selection process provided that certain fundamental, or 'deontological' rights are observed for all. In the light of the discussion the model is modified in order to contain both a non-utilitarian feature that stresses the intrinsic importance of all persons, and a utilitarian feature that can allow one, in certain circumstances, to take consequences into account, especially those that follow from the 'irreplaceability' of some people.

The old Analytical view that the union between the Journey of Telemachus and the rest of the Odyssey is post-Homeric, superficial, and incompetently effected is nowadays widely rejected, and rightly so. However, although many defences cumulatively, I believe, successful–of the content of the second divine assembly have been put forward in recent years, no adequate answer has yet been given to the objections raised against the allegedly anomalous language of Athene's speech of 5.7–20.

In this paper we examine ethical issues relevant to conducting mental health research with refugees and immigrant communities that have cultural orientations and social organisation that are substantially different to those of the broader Australian community, and we relate these issues to NH&MRC Guidelines. We describe the development and conduct of a mental health research project carried out recently in Melbourne with the Somali community, focusing on ethical principles involved, and relating these to the NH&MRC National Statement on Ethical Conduct (...) in Research Involving Humans, and the NH&MRC document Values and Ethics: Guidelines for Ethical Conduct in Aboriginal and Torres Strait Islander Health Research.The experience of conducting mental health research with the Somali community highlights the fact that the principles of inclusion and benefit enunciated in the NH&MRC document Values and Ethics are particularly pertinent when conducting research with refugees and immigrant communities that are culturally distant to those of the broader Australian community. These principles inform issues of research design and consent, as well as guiding respectful engagement with the participating community and communication of the research findings. (shrink)

Alan William Raitt, a Fellow of the British Academy, went up to Magdalen College at the University of Oxford from King Edward's Grammar School in Morpeth, in 1948. He progressed from being an undergraduate there to graduate student, Fellow by Examination, Fellow, Tutor, and Senior Tutor, as well as serving the college as a distinguished Vice-President from 1983 to 1985. Raitt had by then already been named in 1976 Special Lecturer in French Literature for the university and, three years later, (...) University Reader. In 1992 he received the accolade of an ad hominem Chair. Raitt had a gift for friendship; one of his greatest friends was Pierre Castex. His reputation as an international authority on nineteenth-century French literature is second to none. Unlike some British and American scholars, Raitt is widely read and admired by the French themselves, and his name figures prominently in all bibliographies devoted to Villiers de l'Isle-Adam and Gustave Flaubert. Despite his many commitments, both in Oxford and in the sphere of French studies generally, he remained a consistently prolific scholar. (shrink)

A recently published collection of articles focuses upon a relatively small group of texts dealing mainly with astronomical calculations and omens as well as physiognomic omens, attempting to use these as a basis for reconstructing ancient Jewish science in the Persian and Hellenistic periods. The present review raises questions regarding the aims and methods employed, offering an alternative suggestion for the transfer of technical knowledge from Babylonia to ancient Palestine.

Porphyry'sLife of Plotinusis the earliest extant memoir of a philosopher by his pupil. Historians of philosophy have embraced it as a key to the intellectual development of Plotinus, while historians of the third century have found it an invaluable supplement to the fragmentary records of this era. Yet few have cared to read it as an original work of literature, or even as the mature work of a scholar and philosopher who for centuries eclipsed his master in influence, if not (...) in reputation. In consequence, attention has not been paid to certain striking peculiarities in Porphyry's selection and arrangement of materials, which, if studied, will shed light on the form and purpose of the whole biography. This article is devoted to a strange chapter which, as in any ancient writing, we should expect to be the most instructive because it is the first. (shrink)
