While many authors have theorized about the ability of the humanities to enhance business ethics education, scant empirical work exists to support this speculation. We therefore conduct a study to measure the impact of a live theatre performance on ethical reasoning. We asked students to analyze an ethically-laden historical disaster scenario both before and after attending a performance featuring related narrative themes. Our hypothesis is that attending a live performance would cause students to take a more ethical view of an (...) industrial disaster case study. Results show support for the notion that live theatre may impact individuals’ ethical decision-making as applied to a representative business case. Specifically, we found a significant difference in what parties students hold responsible, what actions students think should have been taken, and how cultural norms affect students’ perceptions of ethical obligations. We therefore suggest that live theatre may be a novel pedagogical tool in business ethics education. (shrink)

We comment that covariances between brain divisions may be constraining or facilitating, depending on what is being selected, and that modern quantitative genetic methods provide the tools to discover and manipulate the genetic networks that give rise to the covariances described in the target article.

I offer a critical analysis of a view that has become a dominant aspect of recent thought on the relationship between evolution and morality, and propose an alternative. An ingredient in Michael Ruse's 'error theory' (Ruse 1995) is that belief in moral (prescriptive, universal, and nonsubjective) guidelines arose in humans because such belief results in the performance of adaptive cooperative behaviors. This statement relies on two particular connections: between ostensible and intentional types of altruism, and between intentional altruism and morality. (...) The latter connection is problematic because it makes morality redundant, its role having already been fulfilled by the psychological dispositions that constitute intentional altruism. Both behavioral ecology and moral psychology support this criticism, and neither human behavioral flexibility nor the self-regard / other-regard distinction can provide a defense of the error theory. I conclude that morality did not evolve to curb rampant selfishness; instead, the evolutionarily recent 'universal law' aspect of morality may function to update behavioral strategies which were adaptive in the paleolithic environment of our ancestors (to which our psychological dispositions are best adapted), by means of norms more appropriate to our novel social environment.

A position has been advanced by a number of philosophers, notably by Burnham and Skilleås, that certain knowledge is required to aesthetically appreciate a fine wine. They further argue that pleasure is not an integral part of aesthetically appreciating wine. Their position implies that a novice cannot aesthetically appreciate a fine wine. This paper draws on research into tasting and psychology to rebut these claims. I argue that there is strong evidence from both the average consumer and from wine experts (...) that they are unable to separate enjoyment from aesthetic evaluation; secondly, I argue that wine knowledge may actually preclude tasting of the wine as it exists in the glass due to perceptual bias. I conclude by arguing that it is unclear how exactly knowledge of things like terroir is supposed to affect the taste, as well as question what role conforming to a certain style plays in aesthetic success, as arguments that require knowledge for appreciation typically emphasize knowledge of styles of wine.

The principles of sexual selection were used as an organizing framework for interpreting cross-national patterns of sex differences in mathematical abilities. Cross-national studies suggest that there are no sex differences in biologically primary mathematical abilities, that is, for those mathematical abilities that are found in all cultures as well as in nonhuman primates, and show moderate heritability estimates. Sex differences in several biologically secondary mathematical domains are found throughout the industrialized world. In particular, males consistently outperform females in the solving (...) of mathematical word problems and geometry. Sexual selection and any associated proximate mechanisms influence these sex differences in mathematical performance indirectly. First, sexual selection resulted in greater elaboration in males than in females of the neurocognitive systems that support navigation in three-dimensional space. Knowledge implicit in these systems reflects an understanding of basic Euclidean geometry, and may thus be one source of the male advantage in geometry. Males also use more readily than females these spatial systems in problem-solving situations, which provides them with an advantage in solving word problems and geometry. In addition, sex differences in social styles and interests, which also appear to be related in part to sexual selection, result in sex differences in engagement iii mathematics-related activities, thus further increasing the male advantage in certain mathematical domains. A model that integrates these biological influences with sociocultural influences on the sex differences in mathematical performance is presented in this article. (shrink)

Plagiarism has been a long standing concern within higher education. Yet with the rapid rise in the use and availability of the Internet, both the research literature and media have raised the notion that the online environment is accelerating the decline in academic ethics. The majority of research that has been conducted to investigate such claims have involved self-report data from students. This study sought to collect empirical data to investigate the potential influence the prevalence of the Internet has had (...) on significant higher education artifacts by comparing dissertations written prior to widespread use of the Internet with those written in a period in ubiquitous Internet use. Due to the prestige associated with the doctoral degree and the fact that the majority of the effort necessary to achieve such a degree resides within the dissertation, this study utilized Doctor of Philosophy dissertations written in English and published by accredited universities in the U.S. and Canada. A sample of 384 dissertations were analyzed by Turnitin plagiarism detection software. The mean similarity indices for pre-Internet and post-Internet eras were 14.5 and 12.3 %, respectively. A Mann Whitney U test indicated that the differences between groups was significant, however opposite than has been purported within the exigent literature. When comparing the counts of dissertations for each time era considering those with plagiarism versus those that had little/no evidence thereof, there was no statistically significant difference. The findings of this study suggest that the Internet may not be significantly impacting the prevalence of plagiarism in advanced levels of higher education. (shrink)

In this paper, I will attempt to show how in its reinforcement of relations of subordination, Hegel's conception of the Ethical reveals structural parallels with Antonio Gramsci's notion of hegemony. First, I will analyze Gramsci's notion of hegemony. In his notebooks written in prison between 1929 and 1935, Gramsci employs the term 'hegemony' to focus attention on the determinate role of socio-cultural formations in sustaining relations of domination. In his eyes, a group maintains its supremacy not simply through the direct (...) domination of the coercive state apparatus but also through the organized consent of the governed in civil society. The dominant group thus needs to resort to legal constraint only as a last line of defense, when in times of a crisis of authority the effective self-identification of the governed with the hegemonic formations breaks down. Second, I will attempt to highlight how in Hegel's Philosophy of Right , ethical mediating institutions in civil society, including education, public authorities, and corporations, function in a way similar to Gramsci's notion of hegemony by creating what Hegel himself terms 'a fundamental sense of order' rooted in the 'habit of the Ethical' that promises to organize the more 'spontaneous', 'unhesitating' consent of the collective. Through the formation of this fundamental ethical sense of order, Hegel believes that coercive law may be rendered increasingly 'superfluous'; that is, precisely the role Gramsci sees 'ethical-political hegemony' play in the transition from the 'nightwatchman' to the 'ethical' state. Yet in contrast to Hegel's normative claims, I will try to show how at the level of civil society these ethical mediating institutions in fact fall short of their intended goal. Rather than 'reconcile' individual interest with public utility, they serve to strengthen asymmetrical distributions of power that inhibit the resolution of social conflicts in a mutually beneficial manner. Hegel's conception of the Ethical therefore functions here in a way similar to hegemony to the extent that it molds a sense of order that solidifies relations of subordination. (shrink)

BackgroundThere is increasing need for peer reviewers as the scientific literature grows. Formal education in biostatistics and research methodology during residency training is lacking. In this pilot study, we addressed these issues by evaluating a novel method of teaching residents about biostatistics and research methodology using peer review of standardized manuscripts. We hypothesized that mentored peer review would improve resident knowledge and perception of these concepts more than non-mentored peer review, while improving review quality.MethodsA partially blinded, randomized, controlled multi-center study (...) was performed. Seventy-eight neurology residents from nine US neurology programs were randomized to receive mentoring from a local faculty member or not. Within a year, residents reviewed a baseline manuscript and four subsequent manuscripts, all with introduced errors designed to teach fundamental review concepts. In the mentored group, mentors discussed completed reviews with residents. Primary outcome measure was change in knowledge score between pre- and post-tests, measuring epidemiology and biostatistics knowledge. Secondary outcome measures included level of confidence in the use and interpretation of statistical concepts before and after intervention, and RQI score for baseline and final manuscripts.ResultsSixty-four residents (82%) completed initial review with gradual decline in completion on subsequent reviews. Change in primary outcome, the difference between pre- and post-test knowledge scores, did not differ between mentored (−8.5%) and non-mentored (−13.9%) residents (p = 0.48). Significant differences in secondary outcomes (using 5-point Likert scale, 5 = strongly agree) included mentored residents reporting enhanced understanding of research methodology (3.69 vs 2.61; p = 0.001), understanding of manuscripts (3.73 vs 2.87; p = 0.006), and application of study results to clinical practice (3.65 vs 2.78; p = 0.005) compared to non-mentored residents. There was no difference between groups in level of interest in peer review (3.00 vs 3.09; p = 0.72) or the quality of manuscript review assessed by the Review Quality Instrument (RQI) (3.25 vs 3.06; p = 0.50).ConclusionsWe used mentored peer review of standardized manuscripts to teach biostatistics and research methodology and introduce the peer review process to residents. Though knowledge level did not change, mentored residents had enhanced perception in their abilities to understand research methodology and manuscripts and apply study results to clinical practice.

Acculturation is the process through which an individual's cultural behaviors and values change via contact with a majority or host culture. Although some individuals accomplish acculturation smoothly, most experience psychological stress during the acculturation process. When psychologists encounter individuals struggling to acculturate, they are mandated by ethical guidelines and principles to help through several steps: (a) recognize their own biases, beliefs, and attitudes that may influence their work with the acculturating individual; (b) develop competence to work with individuals whose cultural (...) beliefs and practices differ from their own; (c) counsel the acculturating individual using scientifically supported techniques; and (d) intervene without discrimination or disrespect. Two case studies are presented to illustrate how psychologists can ethically and effectively encourage mentally healthy acculturation. Keywords: acculturation, ethics, cultural differences. (shrink)

Populations around the world are aging at a very fast rate, so much so that care for the elderly will soon rupture even the most carefully planned, enlightened care provisions societies can offer. The demographics in advanced countries demonstrate this dilemma, even without projections based on antiaging medications that may be possible in the near future, and a healthier lifestyle that has preoccupied the yuppies for about 10 years.

In this paper dedicated to Carlos Alchourrón, we review an issue that emerged only after his death in 1996, but would have been of great interest to him: To what extent do the formal operations of AGM belief change respect criteria of relevance? A natural criterion was proposed in 1999 by Rohit Parikh, who observed that the AGM model does not always respect it. We discuss the pros and cons of this criterion, and explain how the AGM account may be (...) refined, if we so desire, so that it is always respected. En este trabajo dedicado a Carlos Alchourrón consideramos un problema que surgió recién después de su muerte en 1996 pero que seguramente habría sido de gran interés para él: ¿hasta dónde las operaciones formales sobre el cambio de creencias de AGM respetan el criterio de relevancia? Un criterio natural ha sido propuesto en 1999 por Rohit Parikh quien asimismo observó que el modelo AGM no siempre lo respeta. Nosotros discutimos los pros y los contras de este criterio y explicamos cómo podría refinarse AGM para que, si así lo deseáramos, lo respetara siempre. (shrink)

Growing ties to private industry have prompted many to question the impartiality of academic bioethicists who receive financial support from for-profit corporations in exchange for ethics-related services and research. To the extent that corporate sponsors may view bioethics as little more than a way to strengthen public relations or avoid potential controversy, close ties to industry may pose serious threats to professional independence. New sources of support from private industry may also divert bioethicists from pursuing topics of greater social importance, (...) such as the needs of medically underserved communities. To inform ongoing debates about the financing of bioethics and its transparency to those concerned about potential sources of bias, we examined funding disclosures appearing in original research reports in major bioethics journals. Reviewing research published over a 15-year period, we found little evidence that for-profit corporations are influencing bioethics research directly. Instead, we found evidence that a great number of organizations, both public and private, support bioethics research. These findings suggest that worries about the cooption of bioethics research by a few interested stakeholders are greatly overstated and undersupported by available data. (shrink)

The target article tends to conflate self-deception and self-enhancement, but biased self-presentation can be negative as well as positive. Self-deceiving self-diminishers may be depressed and non-self-deceiving self-diminishers may project false modesty. The article's otherwise brilliant argument for the advantages of self-deceptive self-enhancement for deceiving others may underemphasize the risks it entails for poor decision making.

The target article's finding of stable and general individual differences in solving of problems in heuristics-and-biases experiments is fundamentally subversive to the Meliorist research program's attention-getting claim that human thought is “systematically irrational.” Since some people get these problems right, studies of heuristics and biases may reduce to repeated demonstrations that difficult questions are hard to solve.

The relation between sex hormones and responses to partner infidelity was explored in two studies reported here. The first confirmed the standard sex difference in relationship jealousy, that males (n=133) are relatively more distressed by a partner’s sexual infidelity and females (n=159) by a partner’s emotional infidelity. The study also revealed that females using hormone-based birth control (n=61) tended more toward sexual jealousy than did other females, and reported more intense affective responses to partner infidelity (n=77). In study two, 47 (...) females were assessed four times across one month. Patterns of response to partner infidelity did not vary by week of menstrual cycle, but significant relations between salivary estradiol level and jealousy responses were obtained during the time of rising and high fertility risk. The implications, at least for females, are that any evolved psychological, affective, or behavioral dispositions regarding reproduction-related relationships are potentially moderated by estradiol, and that the use of synthetic hormones may disrupt this relation.

In this paper I address three problems posed by modern medical technology regarding comatose dying patients. The first is that physicians sometimes hide behind the tests for whole-brain death rather than make the necessary human decision. The second is that the tests themselves betray a metaphysical judgment about death that may be ontologically faulty. The third is that discretion used by physicians and patients and/or family in deciding to cease treatment when the whole-brain death criteria may not be met are (...) sometimes open to challenge. In each of these problems I find that the operative concept of death relates to life itself. This point is expanded by examining the uses of the word death in our language and culture. From these I formulate an initial ontology of death. In it, death is described through a relationship with life, rather than as an absence of life, of consciousness, awareness, or sensation. This ontology then leads to a proposal for an ethics of discretion about the discontinuation of treatment for comatose patients. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:HUME, THE CAUSAL PRINCIPLE, AN'D KEMP SMITH When we say of a proposition that it is possible, we sometimes mean no more than that it is logically possible, that is, consistent with itself. A proposition can be possible in stronger senses than this, but not in any weaker one. For a sense of "p is possible" that did not entail "p is self-consistent, "would have to be a sense (...) of "p is possible" which was consistent with "p is self-inconsistent" And it is obvious that there can be no such sense as that. One of the stronger senses in which a proposition can be possible is this: consistent (with itself and in addition) with every observation-statement. (I mean by an observationstatement, a proposition which, if it were true, could in principle be discovered by experience to be true.) If a proposition? is contingent, (that is, neither necessarily true??t necessarily false), then its negation (its contradictory) not-p is contingent too; and since contingent, not necessarily false; and since not necessarily false, consistent with itself. So, given any contingent propositions, its falsity is among those propositions which are possible in the first and weak sense mentioned above. If a proposition? is not only contingent but unverifiable,(that is, not deducible from any observation- statement), then not-p is consistent both with itself and with every observation -statement. So, given any unverifiable contingent proposition, its falsity is among those propositions which are possible in the second and stronger sense mentioned above. Some stock examples. "Whatever is a raven is black" is contingent, and its falsity therefore possible in the first sense; so too is its contradictory "There are such things as non-black ravens" contingent, and its falsity possible in the first sense. But the latter proposition is not unverifiable, since there are observation-statements from which it is deducible. ("There are such things as green ravens", for example; or "A green raven was in captivity at Taronga Park Zoo in January 31st 1975".) The former proposition, on the other hand, is not only contingent but unverifiable; since there are no observation -statements from which it is deducible. Hence, "whatever is a raven is black" is a proposition the falsity of which is possible both in the first and in the second sense noticed above. A third and still stronger sense in which a proposition can be possible is the following:? is possible if and only if (p is consistent with itself,every observation-statement is consistent with p, and in addition)? is neither more nor less probable in relation to the conjunction of e and n, where e is any observation-statement and? any necessary truth, than it is in relation to? alone. The last condition may be expressed, symbolically, as "P(p/n.e) » P(p/n) for all necessarily true? and all observation-statements e"; or in Carnap' s phrase as, "every observation- statement is initially irrelevant to p." Some examples will quickly make the idea of initial irrelevance, and its opposite, more familiar; and hence will make the third sense of "p is possible" more familiar. Let? be any necessary truth and e any observation-statement. Now let? be, for- example,some necessarily false proposition; then, since P(p/n) « o = P(p/n.e), e is initially irrelevant to p. Or let? be necessarily true; then, since P(p/n) ¦ 1 = P(p/n.e), e is again initially irrelevant to p. Again, let? be "Whatever is a raven is black": then some observation- statements e are initially relevant to p. For if e is "This raven is black," for example, P(p/n.e)>P(p/n) ; or at any rate, that is what we think if we are not inductive sceptic?. Again, if? is "The Holy Ghost proceeds from the Father and the Son", it is at least very plausible to say that every observational e is initially irrelevant to p; since there appears to be no observational e such that P(p/n.e)>P(p/n), or P(p/n.e).

The mammalian pineal gland contains two types of N‐acetyltransferases which act on aromatic amines. One type preferentially acetylates arylamines such as phenetidine and aniline, whereas the other preferentially acetylates arylalkylamines such as tryptamine and phenylethylamine. The two enzymes can be distinguished by (1) molecular size, (2) regulation, and (3) inactivation characteristics. Arylalkylamine N‐acetyltransferase is involved in the regulation of melatonin synthesis in the pineal gland. A specific function of pineal arylamine N‐acetyltransferase has not been established; it may function as a (...) nonspecific detoxification mechanism. (shrink)

The dynamical hypothesis is strong in that, for it to be true, every cognitive phenomenon must be best modeled by a dynamical system. Depending on how it is interpreted, however, the hypothesis may be seen as probably false or even unfalsifiable. Strengthening the hypothesis to require unification, or at least coherence, across models in different cognitive domains alleviates this problem.

Does multilateral action always succeed in creating a Pax Universalis? On the contrary, it may lead to war. With arguments from the U.S. perspective and examples from the Gulf War, Hendrickson sees both collective and unilateral action as neither good nor bad.

Relevance logic is ordinarily seen as a subsystem of classical logic under the translation that replaces arrows by horseshoes. If, however, we consider the arrow as an additional connective alongside the horseshoe and other classical connectives, another perspective emerges. Relevance logic, specifically the system R, may be seen as the output of a conservative extension of classical consequence into the language with arrow.

Relevance logic is ordinarily seen as a subsystem of classical logic under the translation that replaces arrows by horseshoes. If, however, we consider the arrow as an additional connective alongside the horseshoe, then another perspective emerges: the theses of relevance logic, specifically the system R, may also be seen as the output of a conservative extension of the relation of classical consequence. We describe two ways in which this may be done. One is by defining a suitable closure relation out (...) of the set of theses of relevance logic; the other is by adding to the usual natural deduction system for it further rules with ‘projective constraints’, whose application restricts the subsequent application of other rules. The significance of the two constructions is also discussed. (shrink)

In the de Broglie–Bohm formulation of quantum mechanics, the electron is stationary in the ground state of hydrogenic atoms, because the quantum force exactly cancels the Coulomb attraction of the electron to the nucleus. In this paper it is shown that classical electrodynamics similarly predicts the Coulomb force can be effectively canceled by part of the magnetic force that occurs between two similar particles each consisting of a point charge moving with circulatory motion at the speed of light. Supposition of (...) such motion is the basis of the Zitterbewegung interpretation of quantum mechanics. The magnetic force between two luminally-circulating charges for separation large compared to their circulatory motions contains a radial inverse square law part with magnitude equal to the Coulomb force, sinusoidally modulated by the phase difference between the circulatory motions. When the particles have equal mass and their circulatory motions are aligned but out of phase, part of the magnetic force is equal but opposite the Coulomb force. This raises a possibility that the quantum force of Bohmian mechanics may be attributable to the magnetic force of classical electrodynamics. It is further shown that relative motion between the particles leads to modulation of the magnetic force with spatial period equal to the de Broglie wavelength. (shrink)

This has raised concerns about the desirability of the political and economic policies that brought us to this point in history, a period of markedly higher levels of consumptionConsumption that produce higher levels of CO2. That, in turn, has raised new concerns about the ideologies and theoretical paradigms upon which such political and economic policies are based. Many now (...) call for a rejection of free marketFree Market economies to make room for more centrally planned economic systems. Even the idea of Homo EconomicusHomo Economicus – the primary actor in the modern free marketFree Market economy – is under fire in favor of a new conceptualization of the primary actor: Homo CuratorHomo Curator. This essay explains why these changes are both unnecessary and dangerous. I argue they are unnecessary by showing: (1) Homo Economicus and excessive consumptionConsumption are not the root of the problem, and (2) how the theory of market failure already gives us proven means to address problems like global warming. I argue that abandoning Homo Economicus and the free marketFree Market economy is dangerous because it will inevitably lead to a world that is far less likely to support individual and collective human flourishing; one that poorer, less free, and less respectful of the sanctity of the individual.

Spatial and mathematical abilities may be “sex-limited” traits. A sex-limited trait has the same determinants of variation within the sexes, but the genetic or environmental effects would be differentially expressed in males and females. New advances in structural equation modeling allow means and variation to be estimated simultaneously. When these statistical methods are combined with a genetically informative research design, it should be possible to demonstrate that the genes influencing spatial and mathematical abilities are sex-limited in their expression. This approach (...) would give an empirical confirmation of Geary's evolutionary speculations. (shrink)

This paper applies models of the onset of adolescent sexual intercourse using national data from Denmark and the USA. The model gave excellent fits to data on Danish Whites and a good fit to American Whites, but the model-fits for American Blacks and Hispanics were not as good. The weakness of the latter model fits may reflect either real processes that the model does not capture or problems in the reliability of adolescent sexuality data.

Unlike some psychiatric illnesses, criminal lifestyles are not reproductive dead ends and may represent frequency-dependent adaptations. Sociopaths may gain reproductively from their greater relative to nonsociopaths. This mating-effort construct should be assessed directly in future studies of sociopathy.

Howe et al. have mistaken gene x environment correlations for environmental main effects. Thus, they believe that training would develop the same level of performance in anyone, when it would not. The heritability of talents indicates their dependence on variation in physiological (including neurological) capacities.

One twin study of training effects demonstrated greater heritability of (...) physical skill after than before training. In summary, talents are real. (shrink)

The conventional approach to developing disease‐modifying treatments for neurodegenerative conditions has been to identify drivers of pathology and inhibit such pathways. Here we discuss the possibility that the efficacy of such approaches may be increasingly attenuated as disease progresses. This is based on experiments using mouse models of spinocerebellar ataxia type 1 and Huntington's disease (HD), where expression of the dominantly acting mutations could be switched off, as well as studies in human HD, which suggest that the primary genetic driver (...) of age‐of‐onset of disease is a much weaker determinant of disease progression in affected individuals. The idea that one may approach a point in the disease course where such rational therapeutic strategies based on targets which determine onset of disease have minimal efficacy, suggests that one needs to consider other approaches to therapies and clinical trial design, including initiation of therapies in presymptomatic individuals.

Saccadic eye movements create (at least) two related but distinct problems for the visual system: they cause rapid image motion and a displacement of the retinal image. Although it is often assumed that the motion is too fast to be resolved, this is certainly not the case for low-spatial-frequency images. Recent experiments have suggested that the reason we are unaware of the motion during saccades is because motion channels are selectively suppressed, possibly by suppression of the magno-cellular (but not the (...) parvocellular) pathway. This suppression may explain why there is no sensation of motion during saccades, but it leaves open the problem of perceiving a stable world despite continual image displacements. (shrink)

In a 1990 lecture Alasdair MacIntyre identified a number of difficulties in dialogue between philosophers of the Aristotelian and Thomist schools and those of certain modern schools. An examination of various interpretations of Aquinas reveals not only difficulties for inter-school dialogue but for intra-school dialogue as well. Even on foundational topics such as the notion of being, the proper method by which to study being, and the notion of substance, there are divergent opinions about what Aquinas held. This essay argues (...) that certain concepts from Gadamer can be helpful on these disputes. In particular, Gadamer’s ideas that to be is to be manifested, that a perspective-free metaphysics is impossible, and that the relationship between text and performance can serve as a model for understanding the relationship between substance and accident may help to resolve certain internecine disputes within the Aristotelian and Thomist schools as well as to foster philosophical conversation between these approaches and some contemporary schools of thought.

When recalling autobiographical memories, individuals often experience visual images associated with the event. These images can be constructed from two different perspectives: first person, in which the event is visualized from the viewpoint experienced at encoding, or third person, in which the event is visualized from an external vantage point. Using a novel technique to measure visual perspective, we examined where the external vantage point is situated in third-person images. Individuals in two studies were asked to recall either 10 or (...) 15 events from their lives and describe the perspectives they experienced. Wide variation in spatial locations was observed within third-person perspectives, with the location of these perspectives relating to the event being recalled. Results suggest remembering from an external viewpoint may be more common than previous studies have demonstrated. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:53. AN INDEX OF HUME'S REFERENCES IN A TREATISE OF HUMAN NATURE The index below of Hume's references in the Treatise te the works of other authors excludes those which are accurate and full in his text (of which there are few) and those which are so general, e.g., to Spinoza's atheism, that no passage is specifiable. Hume mentions other writings, for which this index is compiled, in several (...) different ways. Occasionally he mentions the author's name, the title of his book and gives a reference which is less specific than it could be. These have been identified. Often he mentions an author's name only, e.g., de Retz, and in such cases the fullest possible reference has been given. One of Hume's notable intellectual gifts was his ability to distil several pages of a book into one or two sentences of crisp and accurate synthesis. (This skill is most apparent in his summaries of articles in Bayle' s Dictionary in his "Notes on Philosophy", of which the manuscript is in the Royal Society of Edinburgh Library.) In these instances, page references are impossible and the closest indication one can give is a section or chapter. Some of his references are anonymous, e.g., as an 'elegant writer' says, and so are some quotations. These have been identified with one exception. One anonymous reference (number 24 below) requires explanation because it is both anachronistic and interesting. Hume refers to an observation by "a late eminent philosopher". It is anachronistic because the book to which he refers was published after the Treatise; it is interesting because it provides further evidence of Hutcheson's influence on Hume and the latter' s regard for him. The explanation, for Hutcheson was still alive when Vol.11 of the Treatise appeared in 1739, is that 'late' is here being used in the sense of 'recent' - Hutcheson himself uses the word in the same way in referring to Mandeville when the latter was 54. alive. (An enquiry concerning moral good and evil. Section 1, VI.) Further, the System circulated widely among Hutcheson's friends in Scotland and over so many years that it finally appeared posthumously. That Hume could not cite a published work also accounts for the anonymity of the reference to someone he admired. It is often impossible to determine in which language or in which edition Hume read a particular author.

In lieu of an abstract, here is a brief excerpt of the content:73. More Hume autograph marginalia in a first edition of the "Treatise". Two sets of marginalia by Hume in copies of the first edition of A Treatise of Human Nature have been published. One is a copy in the British Library. This has 1 2 been described by Connon and Nidditch and was, no doubt, one, at least, of the copies which Hume kept for himself. The marginalia are (...) so extensive as to suggest that, at the time he made them, he may have been hoping for an opportunity to publish a second edition of the Treatise. The other copy with marginalia, a presentation copy to his kinsman, Henry Home, Lord Karnes, has been described by Wallace Nethery, Librarian of the Hóose Library of Phil3 osophy and by Nidditch. There is a third copy of the Treatise with marginalia in Hume's hand which was a pre4 sentation copy to Pope. The Pope copy is inscribed on the flyleaf of Volume I in Hume's handwriting, "To Alexander* Rope Esq at Twickenham". There are 18 corrections in Volume I and 5 in Volume II. They are as follows, the first word or phrase being the error, the second the correction. The first word is usually scratched out in the text and the correction inserted in the margin but sometimes insertions are simply made within the text. 1st EditionSelby-Bigge 1.12.252.8'the' Our' 1.35.2316.1'of 'or' 1.57.428.18'these* 'those' 1.58.829.6'part' 'parts' 1.111.2860.27'defection' 'dissection' 1.126.569.14'it' deleted 1.154.486.1'worn out' "worn it out' 1.240.7136.9'as' 'when' 1.256.21145.28'evidence' 'testimony' 74. ï. 273. 20155.24'instance' 'instances' 1.280.16159.33'gave it's' 'gave it its' Ï.286.25163.22-23'upon observation' 'upon the observation' 1.287.16164.2'cause' 'case' 1.288.5164.15'results* 'result' 1.293.10167.14'exists' 'exist' 1.343.17196.22'opening I' 'opening it I' 1.402.16231.6'presses' 'press' 1.453.1260.34'what the' 'what is the' 11.108.10 336.24 "affections wheel' 'affections to wheel' II. 120. 4 343.19 'cause' 'causes' 11.228.23404.15 'One' Our' 11.229.19 404.32 'and proceed' 'and practice proceed' 11.271.24428. 20 'considerably' 'sensibly' In addition, someone, perhaps Hume, has marked a printer's error where a letter has slipped. (Vol. I, p. 466. 3). It is not possible to find out the date upon which Hume gave this copy to Pope from the published correspondence of either party. Pope died in 1744 and Hume may have sent him a copy of the Treatise because of the former's literary renown and because the publishers had a large number of unsold copies on their hands. From the fact, among others, that the footnote on Volume II, p. 168 (Selby-Bigge, p. 371) is missing from both the Pope1 and the Karnes copies, it is clear that Volumes I and II were, as one might expect of presentations, in each case early issues or states. It is more than likely that Hume made other presents of the Treatise to friends and people he admired such as Francis Hutcheson and Bishop Butler, and these 75. would probably have included marginalia along the same lines as the Karnes and Pope copies. For what Hume substantially did in giving these copies was to perform an act of courtesy; i.e., to incorporate items from the errata tables into the text. The Pope copy is the least important and interesting of those noticed so far, for it contains only one correction which is not included in the errata tables - the second item listed above in Volume I - and not all of them. The percentage of the changes called for in the errata tables which are made by Hume in the text diminishes markedly as between Volumes I and II. Moreover, there are no marginalia in the third volume, 'Of Morals', and this is perhaps to be explained by Hume's becoming bored with this somewhat superfluous task, even if it was a politeness and the fact...

According to the mainstream conception of research involving human participants, researchers have been trained scientists acting within institutions and have been the individuals doing the studying, while participants, who are nonscientist members of the public, have been the individuals being studied. The relationship between the public and scientists is evolving, however, giving rise to several new concepts, including crowdsourcing and citizen science. In addition, the practice of gamification has been applied to research protocols. The role of gamified, crowdsourced citizen scientist (...) is new in the domain of scientific research and does not fit into the existing taxonomy of researchers and participants. We delineate and explicate this role and show that, while traditional roles are governed by well‐established norms and regulations, individuals engaged in gamified, crowdsourced citizen science—gamers—fall through the cracks of research protections and regulations. We consider the issues this raises, including exploitation and the absence of responsibility and accountability. Finally, we offer suggestions for how the current lack of appropriate norms may be rectified. (shrink)

This article presents a sobering view of the discipline of cognitive neuropsychology as practiced over the last three or four decades. Our judgment is that, although the study of abnormal cognition resulting from brain injury or disease in previously normal adults has produced a catalogue of fascinating and highly selective deficits, it has yielded relatively little advance in understanding how the brain accomplishes its cognitive business. We question the wisdom of the following three “choices” in mainstream cognitive neuropsychology: (a) single‐case (...) methodology, (b) dissociation between functions as the most important source of evidence, and (c) a central goal of diagramming the functional architecture of cognition rather than specifying how its components work. These choices may all stem from an excessive commitment to strict and fine‐grained modularity. Although different brain regions are undoubtedly specialized for different functions, we argue that parallel and interactive processing is a better assumption about cognitive processing. The essential goal of specifying representations and processes can, we claim, be significantly assisted by computational modeling which, by its very nature, requires such specification. (shrink)

Global consumption, production, and trade of livestock products have increased rapidly in the last two decades and are expected to continue. At the same time, safety concerns regarding human and animal disease associated with livestock products are increasing. Efforts to increase public health safety standards aimed at legitimately reducing the risks of human and animal disease have focused internationally on standards to regulate the movement of livestock products. There is concern, though, that measures to regulate these standards internationally, such as (...) the WTO SPS measures that in part aim to open international markets, may marginalize small-scale poor producers. The cycle of poverty they are trying to escape through livestock production may, in fact, widen, leading to increased global poverty, malnutrition, and disease. Developing and developed nations alike should be concerned with public and private efforts to address appropriate food safety policies to reduce the likelihood of this effect. Analysis of the impact on small-scale livestock farmers is needed, as well as solutions that consider joint public and private sector initiatives. Costly farm to table tracking systems are not an option, but locally orchestrated vertically integrated systems may have merit in reducing food safety risks and in providing small-scale farmers with increased access to markets, locally and internationally. Increased scientific and technical capacity, and training of WTO officials from developing nations is also needed. (shrink)

Various philosophers discuss perlocutionary silencing, but none defend an account of perlocutionary silencing. This gap may exist because perlocutionary success depends on extralinguistic effects, whereas silencing interrupts speech, leaving theorists to rely on extemporary accounts when they discuss perlocutionary silencing. Consequently, scholars assume perlocutionary silencing occurs but neglect to explain how perlocutionary silencing harms speakers as speakers. In relation to that shortcoming, I defend a novel account of perlocutionary silencing. I argue that speakers experience perlocutionary silencing when they are illegitimately (...) deprived of perlocutionary influence on a conversation in which they are active participants, where perlocutionary influence on the conversation relates to speech-related perlocutionary goals meant to influence the conversation or conversational direction. Thus, this account grounds perlocutionary silencing in linguistic phenomena and characterizes perlocutionary silencing in a way that explains why those who experience perlocutionary silencing are harmed as speakers. Moreover, this account explains how perlocutionary silencing harms speakers as conversational participants in a way that cannot be captured by illocutionary or locutionary silencing, for a speaker may be perlocutionarily silenced despite illocutionary success. Consequently, the account explains why “All Lives Matter” silences Black Lives Matter and “Not All Men” silences women sharing experiences of sexual harassment. (shrink)

The exportation of Western biomedicine throughout the world has not resulted in a systematic homogenization of scientific ideology but rather in the proliferation of many forms and practices of biomedicine. Similarly, in the last decade, bioethics has become increasingly an international enterprise. Although there may be consensus regarding the inherent value of ethical discourse as it relates to health and medical care, there are disagreements about the nature and parameters of medical morality. This lack of consensus exists because our beliefs (...) about morality are culturally constituted, embedded in social, religious, and political ideologies that influence particular individuals and communities at specific historical moments.

For those who are eagerly awaiting the return of Christ in glory, the admonition articulated in Matthew 24:42 has always been of paramount importance. Not only are we counseled to remain ever vigilant, but the intellectual boundaries within which we may abide in our expectation are also carefully delineated, for it is here that Christ most firmly establishes his mandate that we profess a radical agnosticism regarding the time-tables of sacred history. Nonetheless, since the days of the Church Fathers there (...) have been some who, for a variety of reasons, have sought to arrive at a more certain — or at least more refined — understanding of the timing of the Parousia, most often through a combination of exegesis and numerology. To a certain degree, Christian of Stavelot's comments on Matthew 24:42 must be considered among these attempts. (shrink)

Many commentators agree with our view that the problem-oriented approach to social psychology has not fulfilled its promise, and they suggest new research directions that may contribute to the maturation of the field. Others suggest that social psychology is not as focused on negative phenomena as we claim, or that a negative focus does indeed lay the most efficient path toward a general understanding of social cognition and behavior. In this response, we organize the comments thematically, discuss them in light (...) of our original exposition, and reiterate that we seek not a disproportionately positive social psychology but a balanced field that addresses the range of human performance.

The existing literature in medical ethics does not serve the practical needs of medical students and trainees very well. Medical students or junior doctors often have their own set of ethical concerns and the dilemmas that arise are generally beyond their direct control. The editors have addressed the gap in the literature by compiling a series of case studies from around the world and inviting an international team of leading ethicists and clinicians to comment on them. This volume includes over (...) 80 actual cases that cover the range of possible problems a medical trainee may encounter on the ward. (shrink)
