A project on teaching business ethics at The Wharton School concluded that ethics should be directly incorporated into key MBA courses and taught by the core business faculty. The project team, comprised of students, ethics faculty and functional business faculty, designed a model program for integrating ethics. The project was funded by the Exxon Education Foundation.The program originates with a general introduction designed to familiarize students with literature and concepts pertaining to professional and business ethics and corporate social responsibility. This (...) may be accomplished through orientation sessions, readings, packages, short classes and lectures. (shrink)

This collection of essays, offered in honor of the distinguished career of prominent political philosophy professor Clifford Orwin, brings together internationally renowned scholars to provide a wide context and discuss various aspects of the virtue of “humanity” through the history of political philosophy.

Cross-cultural studies have revealed broad quantitative associations between subsistence practice and demographic parameters for preindustrial populations. One explanation is that variationin the availability of suitable weaning foods influenced the frequency and duration of breastfeeding and thus the length of interbirth intervals and the probability of child survival (the “weaning food availability” hypothesis). We examine the available data on weaning age variation in preindustrial populations and report results of a cross-cultural test of the predictions that weaning occurred earlier in agricultural and (...) pastoral populations because dairy and cereal production increased the availability of easily digestible, nutrientrich foods appropriate for weaning. We found that, contrary to predictions, supplementation with liquid foods other than breast milk was delayed in agricultural populations relative to less agriculturally dependent ones and complementary feeding with solid foods was delayed in pastoral populations relative to those less dependent on herding. Although the duration of breastfeeding was longer in populations dependent on hunting, there was no qualitative evidence that such populations lacked foods appropriate for weaning. The patterns observed suggest that the relationships between demography and subsistence observed among preindustrial societies cannot be explained by the “weaning food availability” hypothesis. We discuss the implications for understanding the mechanisms underlying prehistoric human demography, subsistence shifts, allocation to parenting and mating effort, and the evolutionary implications of tradeoffs between diet and disease.

Little is known empirically about the role of supervisor listening and the emotional conditions that listening facilitates. Having the opportunity to speak is only one part of the communication process between employees and supervisors. Employees also react to whether they perceive the supervisor as actively listening. In two studies, this paper examines three important outcomes of employee perceptions of supervisor listening. Furthermore, positive and negative affect are investigated as distinct mediating mechanisms. Results from Study 1 revealed that employee perceptions of (...) supervisor listening reflected supervisors’ self-ratings of how they listen to their employees and these perceptions were associated with the three work outcomes. Study 2 replicated the findings in a larger sample and found evidence for two explanatory mechanisms. Positive affect mediated the effects of perceived supervisor listening on organizational citizenship behavior and turnover intention, whereas negative affect mediated listening effects on emotional exhaustion and turnover intention. Implications for organizational research and managerial practice concerning workforce sustainability are discussed. (shrink)

New fetal therapies offer important prospects for improving health. However, having to consider both the fetus and the pregnant woman makes the risk–benefit analysis of fetal therapy trials challenging. Regulatory guidance is limited, and proposed ethical frameworks are overly restrictive or permissive. We propose a new ethical framework for fetal therapy research. First, we argue that considering only biomedical benefits fails to capture all relevant interests. Thus, we endorse expanding the considered benefits to include evidence-based psychosocial effects of fetal therapies. (...) Second, we reject the commonly proposed categorical risk and/or benefit thresholds for assessing fetal therapy research. Instead, we propose that the individual risks for the pregnant woman and the fetus should be justified by the benefits for them and the study’s social value. Studies that meet this overall proportionality criterion but have mildly unfavorable risk–benefit ratios for pregnant women and/or fetuses may be acceptable. (shrink)

In this exploratory study, higher education faculty perceptions regarding acceptability of social media use for out-of-class student engagement are identified. Hypotheses are developed and tested using a survey to address the impact of factors such as awareness, faculty/student relationship status, gender, academic discipline, and rank on faculty attitudes toward out-of-class social media use for student engagement. Findings indicate that faculty members are aware of social media, but use varies. Overall, they do not view social media as an important part of (...) out-of-class engagement, but it is viewed as more acceptable for engagement with former students. In addition, faculty from Marketing and Communications disciplines and Associate/Full Professors perceive social media use to be more acceptable for student engagement when compared with their colleagues from other disciplines and lower ranks. Implications and conclusions are discussed for development of university social media usage policies and directions for future research. (shrink)

Cortical stimulation has been used for brain mapping for over a century, and a standard assumption is that stimulation interferes with task execution due to local effects at the stimulation site. Stimulation can however produce afterdischarges which interfere with functional localization and can lead to unwanted seizures. We previously showed that cognitive effort can terminate these afterdischarges, when termination thus occurs, there are electrocorticography changes throughout the cortex, not just at sites with afterdischarges or sites thought functionally important for the (...) cognitive task used, and thresholds for afterdischarges and functional responses can change among stimulation trials. We here show that afterdischarge termination can occur prior to overt performance of the cognitive tasks used to terminate them. These findings, taken together, demonstrate that task-related brain changes are not limited to one or a group of functional regions or a specific network, and not limited to the time directly surrounding overt task execution. Discrete locations, networks and times importantly underpin clinical behaviors. However, brain activity that is diffuse in location and extended in time also affect task execution and can affect brain mapping. This may in part reflect fluctuating levels of attention, engagement, or motivation during testing. (shrink)

Participation in collective action is known to be driven by two appraisals of a social situation: Beliefs that the situation is unfair and beliefs that a group can change the situation. Anger has been repeatedly found to mediate the relationship between injustice appraisals and collective action. Recent work suggests that the emotion of being moved mediates the relationship between efficacy appraisals and collective action. Building on this prior work, the present research applies kama muta theory to further investigate the relationship (...) between efficacy appraisals and collective action. Kama muta is a positive emotion that is evoked by a sudden intensification of communal sharing, and largely overlaps with the English concept being moved. We investigated its relationship with collective action in both advantaged and disadvantaged racial groups in the context of the Black Lives Matter Movement in Spring of 2020. In one pilot study and one main study, we confirmed that anger toward the system of racial inequalities mediated between injustice and collective action intentions, and that kama muta toward the movement mediated between collective efficacy and collective action intentions. Both mediations were found for both Black and White participants. We also observed additional unpredicted paths from anger to kama muta and from efficacy to anger. Together, this provides evidence for the pivotal role of emotions in collective action intentions, but also points out that appraisals need to be better understood. (shrink)

The popular media has repeatedly pointed to pride as one of the key factors motivating leaders to behave unethically. However, given the devastating consequences that leader unethical behavior may have, a more scientific account of the role of pride is warranted. The present study differentiates between authentic and hubristic pride and assesses its impact on leader ethical behavior, while taking into consideration the extent to which leaders find it important to their self-concept to be a moral person. In two experiments (...) we found that with higher levels of moral identity, authentically proud leaders are more likely to engage in ethical behavior than hubristically proud leaders, and that this effect is mediated by leaders’ motivation to act selflessly. A field survey among organizational leaders corroborated that moral identity may bring the positive effect of authentic pride and the negative effect of hubristic pride on leader ethical behavior to the forefront.

_341_ _Objectives: _In patients with multivessel disease both the detection of the culprit lesion and the exact allocation are important preconditions for sufficient treatment and improved outcome. In a vessel based approach the combination of quantitative coronary angiography and fractional flow reserve measured by a pressure wire should be advantageous compared to myocardial SPECT, as morphological and functional information is delivered simultaneously. Therefore our aim was to evaluate MS in the detection and allocation of hemodynamically significant stenoses obtained by the (...) combined gold standard QCA plus FFR in patients with multivessel disease. _Methods: _FFR and QCA of 95 vessels in 80 patients have been evaluated. Hemodynamically significant target lesions were defined as intermediate stenoses between 50 and 75% with an FFR. (shrink)

Originating from two conferences that took place in September 2013 and June 2015 at Sapienza University of Rome, this outstanding specialist volume aims to systematically illuminate the arguments that Aristotle uses in trying to establish the ‘first principles’ of his natural philosophy in Physics I. Not only is it successful in achieving this overall goal, but it is also timely, as its publication anticipates the forthcoming proceedings of the July 2014 Symposium Aristotelicum, devoted to the Physics.

How is women’s conception of self affected by the caregiving responsibilities traditionally assigned to them and by the personal vulnerabilities imposed on them? If institutions of male dominance profoundly influence women’s lives and minds, how can women form judgments about their own best interests and overcome oppression? Can feminist politics survive in face of the diversity of women’s experience, which is shaped by race, class, ethnicity, and sexual orientation, as well as by gender? Exploring such questions, leading feminist thinkers have (...) reinvigorated work on the concept of self and personal identity, as demonstrated by the discussions in this insightful volume.The concerns that animate feminist scholarship have prompted feminist philosophers to sideline the theme of individualism and to focus on the theme of intersubjectivity. In conceptualizing the self, the contributors to this volume highlight emotional bonds among people, the stories people tell one another, and the systems of categories and behavioral norms that unite and divide groups of people. Topics addressed include sexual violence and the self, the social self and autonomy, the narrative self and integrity, self-ownership and the body, forgetting yourself and your race, group membership and personal identity, grief and gender, sympathy and women’s diversity, emotion and emancipatory epistemology, and dependency and justice. This volume will be important reading for students of feminist theory, ethics, and social and political philosophy. (shrink)

This book tackles how and why 'landscape' (farms, gardens, countryside) set the scene in the first centuries BCE and CE for Romans keen to talk up and about (but also to scrutinize and understand) what it meant to be a citizen. It investigates what 'landscape' means now and reflects upon how contemporary approaches to 'landscape' can enrich our understanding of ancient experience of the interface between natural and artificial space. It encourages examination of 'landscape' from a range of angles, suggesting (...) alternative ways of thinking about what landscape represents. These methodological approaches (presented initially via a set of key terms and definitions and then deployed thematically across four chapters), combined with a detailed interdisciplinary bibliography and a series of case studies of literary texts and material sites, enable readers to use this survey as a starting point for developing their own in-depth study.

According to the standard view, the function of the unlimited dunamis argument (Physics VIII.10, Metaphysics Λ.7 1073a5–11) is to introduce a new property of the first immovable mover, namely its lack of magnitude. The paper challenges this view and argues that the argument at issue serves to prove that the eternal motion of the first heavenly sphere is caused by an immovable mover rather than by a moved mover. Further, the paper shows that, at least in Phys. VIII, the unlimited (...) dunamis argument is the main argument for the immobility of the Prime Mover. (shrink)

Normal 0 21 false false false MicrosoftInternetExplorer4 One of the most important questions of moral philosophy is what makes a life a good life. A good way of approaching this issue is to watch the film Groundhog Day which can teach us a lot about what a good life consists in - and what not. While currently there are subjective and objective theories contending against each other about what a good life is, namely hedonism and desire satisfaction theories on the (...) one hand and objective list theories on the other, the film illustrates that at least one constituent of the good life can only be understood if we see it as having both an objective and a subjective side to it. Thus, the film shows that, in contrast to the beginning of the film, at the end the protagonist Phil has a good life insofar as that he finds something to do that suits him (the objective element), and comes to care deeply about it (the subjective element).

The question of what it means to be human has never before been more difficult and more contested. The human, with a complicated social history that his rarely been examined, remains entrenched in traditional Enlightenment thinking. Human, All Too Human considers how we might radicalize our notion of the human. Can the human be thought outside humanism? Any rethinking of the human places us immediately inside an ever-widening field of contrasting labels: animate and inanimate, natural and artificial, living and dead, (...) organic and mechanistic. These and other boundary confusions at the frontier of the human are the subject of this volume, as each essay takes up one of three disputed border identities: animals, things or children. Human, All Too Human examines how we explain our interest in anthropomorphism and our fascination with species categorizations. Essays explore what we mean by "things" and how the integrity of the human may already be compromised by them. The nine essays in this volume all attempt to rethink the category of the human, challenging some of our most cherished cultural classifications. By inviting us to place the traditions subject of knowledge in the unsettling position of object, these writers interrogate the boundary distinctions that, until now, have exempted the human from the vigilant analysis it so urgently requires.
