Despite claims to the contrary, the science of ecology has a long history of building theories. Many ecological theories are mathematical, computational, or statistical, though, and rarely have attempts been made to organize or extrapolate these models into broader theories. The Theory of Ecology brings together some of the most respected and creative theoretical ecologists of this era to advance a comprehensive, conceptual articulation of ecological theories. The contributors cover a wide range of topics, from ecological niche theory to population (...) dynamic theory to island biogeography theory. Collectively, the chapters ably demonstrate how theory in ecology accounts for observations about the natural world and how models provide predictive understandings. It organizes these models into constitutive domains that highlight the strengths and weaknesses of ecological understanding. This book is a milestone in ecological theory and is certain to motivate future empirical and theoretical work in one of the most exciting and active domains of the life sciences. (shrink)

At the end of their article in the September 2014 issue of the Journal of Business Ethics, Douglas R. May, Matthew T. Luth, and Catherine E. Schwoerer state that they are “hopeful in outlook” about the “evidence that business ethics instructors are….able to encourage students…to develop the courage to come forward even when pressures in organizations dictate otherwise”. We agree with May et al. that it is essential to augment students’ moral courage. However, it seems overly optimistic to believe that (...) this improvement will result from any course in business ethics. Indeed, we question the appropriateness of their measure of moral courage and assert that business ethics educators must purposely design their courses to develop students’ moral courage. In particular, we advocate introducing business ethics students to works of literature featuring protagonists who exercise moral courage in organizations. Fiction provides rich accessible narratives that show students worlds beyond their experience, awaken their imaginations, and evoke their emotions. Further, we highlight morally courageous exemplars because they inspire the cultivation of character. Joining those who underscore the role of virtue in business ethics education, we argue that exposure to moral exemplars in fiction will help students to build the moral courage they need to carry out ethical decisions in the workplace. Results from 46 students at the end of an MBA ethics course featuring moral courage provide preliminary evidence of the effectiveness of our approach. (shrink)

This paper examines the problem of vituperative feedback from peer reviewers. We argue that such feedback is morally unacceptable, insofar as it humiliates authors and damages their dignity. We draw from social-psychological research to explore those aspects of the peer-review process in general and the anonymity of blind reviewing in particular that contribute to reviewers’ humiliating comments. We then apply Iris Murdoch's ideas about a virtuous consciousness and humility to make the case that peer referees have a moral obligation not (...) to humiliate the authors whose work they review.

We develop an account of laboratory models, which have been central to the group selection controversy. We compare arguments for group selection in nature with Darwin's arguments for natural selection to argue that laboratory models provide important grounds for causal claims about selection. Biologists get information about causes and cause-effect relationships in the laboratory because of the special role their own causal agency plays there. They can also get information about patterns of effects and antecedent conditions in nature. But to (...) argue that some cause is actually responsible in nature, they require an inference from knowledge of causes in the laboratory context and of effects in the natural context. This process, cause detection, forms the core of an analogical argument for group selection. We discuss the differing roles of mathematical and laboratory models in constructing selective explanations at the group level and apply our discussion to the units of selection controversy to distinguish between the related problems of cause determination and evaluation of evidence. Because laboratory models are at the intersection of the two problems, their study is crucial for framing a coherent theory of explanation for evolutionary biology. (shrink)

Entrepreneurship is a critical need in society, and an entrepreneur's life can be a life wonderfully lived. However, most of the literature examining entrepreneurship takes an overly narrow financial viewpoint when examining entrepreneurship and entrepreneurial success. Our paper surveys the current entrepreneurial literature on what constitutes successful entrepreneurship. We then engage key conceptual ideas within the Catholic social tradition to analyze what we see as an undeveloped notion of success. We then move to construct a richer notion of success through (...) the framework of virtue. (shrink)

The idea that oxidative stress may underpin life history trade‐offs has become extremely popular. However, experimental support for the concept has proved equivocal. It has recently been suggested that this might be because of flaws in the design of existing studies. Here, we explore the background to the oxidative stress hypothesis and highlight some of the complexities in testing it. We conclude that the approach recently suggested to be least useful in this context (comparing reproducing to non‐reproducing animals) may in (...) fact be the most powerful. Moreover, suggested alternative approaches of limiting food supply or manipulating litter sizes have many complexities and problems. We suggest some useful alternative approaches that have not been previously advocated, particularly the study of individuals reproducing at greater parity later in life. Finally, the measures of oxidative stress and tissues that are analysed influence the experimental outcome. This suggests our conceptual model of the trade‐off is currently too simplistic, and that studies based on single or limited numbers of assays, or restricted to single tissues, whether they support or refute the theory, should be interpreted with great caution.

: Research involving the dead, especially heart-beating cadavers, may facilitate the testing of potentially revolutionary and life-saving medical treatments. However, to ensure that such research is conducted ethically, it is essential to: (1) identify appropriate standards for this research and (2) assign institutional responsibility and a mechanism for oversight. Protocols for research involving the dead should be reviewed by a special committee and assessed according to nine standards intended to ensure scientific merit, to protect deceased patients and their families, and (...) to promote institutional integrity and responsibility. Federal regulation of research involving the dead will foster appropriate standards and, equally importantly, help establish the acceptability of such research. (shrink)

Vaccine hesitancy is a major public health challenge, and racial disparities in the acceptance of vaccines is a particular concern. In this essay, we draw on interviews with mothers of Black male adolescents to offer insights into the reasons for the low rate of vaccination against the human papillomavirus among this group of adolescents. Based on these conversations, we argue that increasing the acceptance of HPV and other vaccines cannot be accomplished merely by providing people with more facts. Instead, we (...) must address the pervasive racial discrimination in the United States that undermines trust in social institutions, including the health care system. In the short term, it may be helpful to increase the number of clinicians of color working in the health system, but more fundamental changes are required. The U.S. must adopt and implement policies that dismantle structural racism if it hopes to produce greater trust and community‐oriented thinking on behalf of people who have been exploited for centuries.

In small-scale societies, punishment of adults is infrequent and employed when the anticipated cost-to-benefit ratio is low, such as when punishment is collectively justified and administered. In addition, benefits may exceed costs when punishers have relatively greater physical and social capital and gain more from cooperation. We provide examples from the Tsimane horticulturalists of Bolivia to support our claims.

Moral foundations theory provides a theoretical framework for understanding the universal and societal aspects of morality. The focus thus far has been on understanding the influence of group categories on moral foundations by controlling for relevant factors and then examining the unique contribution of a single factor. Although this type of analysis was critical to demonstrate the efficacy of the Moral Foundations Theory and Moral Foundations Questionnaire, the current study examines moral responses from the intersection of culture, ethnic identity and (...) gender group membership in the United States and India. Significant results suggest that moral foundations are better understood through a multiple group identity perspective and that the MFQ is equipped to capture differences in moral foundations within subgroups.

Business ethics educators have been encouraged to cultivate students’ character, but have received meager instructions for doing so. Additionally, there has been insufficient focus on equipping students with the tools they need to foster their ethical development after completing our courses. In this paper, it is argued that the Jewish spiritual practice of Mussar, whose premise is that individuals can become better versions of themselves by repairing their character traits, can inform business ethics instruction. After presenting the tenets and historical (...) background of Mussar, we provide specific information that will enable business ethics instructors to adapt its tools and techniques in order to put their students on a personalized path of lifelong character improvement.

Heisenberg'sgendanken experiments in quantum mechanics have given rise to a widespread belief that the indeterminacy relations holding for the variables of a quantal system can be explained quasiclassically in terms of a disturbance suffered by the system in interaction with a quantal measurement, or state preparation, agent. There are a number of criticisms of this doctrine in the literature, which are critically examined in this article and found to be ininconclusive, the chief error being the conflation of this disturbance with (...) the projection postulate. We present a critique of the disturbance theory based on the fact that the required disturbance will in general depend on the interaction time of the system and state-preparer. This point is exploited in the construction of a spin-interaction model which acts as a counterexample to the disturbance doctrine, while remaining faithful to the spirit of Heisenberg'sgedanken experiments. Several consequences of this result are discussed. (shrink)

The Covid-19 pandemic raised questions about the viability of food chains and created new opportunities for small-scale producers. This study reports on findings from a project directed at investigating how niche meat farmers respond to external challenges and threats including those related to their position as small-scale producers and those that are pandemic-related. A purposeful sample (_N_ = 5) of local meat producers in NC, recruited through their producer network, were interviewed twice (in 2021 and again in 2022) via Zoom. (...) Informants were interviewed about the characteristics of their farm enterprises and households. The niche meat farmer informants in this study are diversified, values-based operations that utilize pasture-based production practices. They draw upon their farm enterprise and household assets, including the allocation of labor to farm, non-farm, and household activities, to meet economic production and social reproduction needs. Overall, our results show that the resiliency of the niche-meat producers flows from this integration of the farm enterprise and the household. While the data are based on a very limited sample, the results are consistent with literatures on women in agriculture and peasant economy. Therefore, we argue that future studies of how small-scale farms react to exogenous change, like the pandemic, include details on household composition and the gender division of labor for on-farm, off-farm, and social reproduction activities.

The increasing effort, both lay and academic, to encourage a transition from an “I-It” to an “I-Thou” relation to nature is located within a typology of ways of “knowing nature.” This typology provides the context for a particular understanding of human conversation which sees the relation as a cyclical process of “immersion” and “realization” from which a model of the dialectic between “I-It” and “I-Thou” relations to nature can be developed. This model can be used to identify practical measures that (...) can be taken as first steps toward a balance between these relations, both in general and in the context of science-oriented nature conservation organizations such as English Nature in Britain.

We analyze naturally occurring datasets from student use of educational technologies to explore a long-standing question of the scope of transfer of learning. We contrast a faculty theory of broad transfer with a component theory of more constrained transfer. To test these theories, we develop statistical models of them. These models use latent variables to represent mental functions that are changed while learning to cause a reduction in error rates for new tasks. Strong versions of these models provide a common (...) explanation for the variance in task difficulty and transfer. Weak versions decouple difficulty and transfer explanations by describing task difficulty with parameters for each unique task. We evaluate these models in terms of both their prediction accuracy on held-out data and their power in explaining task difficulty and learning transfer. In comparisons across eight datasets, we find that the component models provide both better predictions and better explanations than the faculty models. Weak model variations tend to improve generalization across students, but hurt generalization across items and make a sacrifice to explanatory power. More generally, the approach could be used to identify malleable components of cognitive functions, such as spatial reasoning or executive functions. (shrink)

Based on the distinction between living body and lived body, we describe the disease-subject as representing the impact of disease on the existential life-project of the subject. Traditionally, an individual's subjectivity experiences disorders of the body and describes ensuing pain, discomfort and unpleasantness. The idea of a disease-subject goes further, representing the lived body suffering existential disruption and the possible limitations that disease most probably will impose. In this limit situation, the disease-subject will have to elaborate a new life-story, a (...) new character or way-of-being-in-the-world, it will become a different subject. (shrink)

Mind-body interactions have been the subject of debate for many generations. However, it is only in recent years that these interactions have become the subject of rigorous scientific enquiry. In recent years there have been major advances in our understanding of the stress process, the endocrine and immune systems, and the methodologies used to investigate these phenomena. As a result, we have witnessed an explosion of research activity in the field known as psychoneuroimmunology - the study of psychological processes and (...) their interaction with the nervous and immune systems. This book presents an up to date account of the human evidence in this field. The first three chapters introduce the reader to the biological systems at the heart of mind/body interactions and the methods used to investigate them. Thereafter, each chapter deals with a separate clinical entity; examining the theoretical basis for mind/body interactions; the associated empirical evidence and directions for future research. With each chapter written by international experts in the field, it provides the reader with an up to date account of the research evidence in the rapidly evolving field of psychoneuroimmunology.

In a previous study, using experimental metapopulations of the flour beetle, Tribolium castaneum, we investigated phase III of Wright's shifting balance process (Wade and Griesemer 1998). We experimentally modeled migration of varying amounts from demes of high mean fitness into demes of lower mean fitness (as in Wright's characterization of phase III) as well as the reciprocal (the opposite of phase III). We estimated the meta-populational heritability for this level of selection by regression of offspring deme means on the weighted (...) parental deme means.Here we develop a Punnett Square representation of the inheritance of the group mean to place our empirical findings in a conceptual context similar to Mendelian inheritance of individual traits. The comparison of Punnett Squares for individual and group inheritance shows how the latter concept can be rigorously defined and extended despite the lack of explicitly formulated, simple Mendelian laws of inheritance at the group level. Whereas Wright's phase III combines both interdemic selection and meta-populational inheritance, our formulation separates the issue of meta-populational heritability from that of interdemic selection. We use this conceptual context to discuss the controversies over the levels of selection and the units of inheritance. (shrink)

In recent years, the changing landscape for the conduct and assessment of research and of researchers has increased scrutiny of the reward systems of science. In this context, correcting the research record, including retractions, has gained attention and space in the publication system. One question is the possible influence of retractions on the careers of scientists. It might be assessed, for example, through citation patterns or productivity rates for authors who have had one or more retractions. This is an emerging (...) issue today, with growing discussions in the research community about impact. We have explored the influence of retractions on grant review criteria. Here, we present results of a qualitative study exploring the views of a group of six representatives of funding agencies from different countries and of a follow-up survey of 224 reviewers in the US. These reviewers have served on panels for the National Science Foundation, the National Institutes of Health, and/or a few other agencies. We collected their perceptions about the influence of self-correction of the literature and of retractions on grant decisions. Our results suggest that correcting the research record, for honest error or misconduct, is perceived as an important mechanism to strengthen the reliability of science, among most respondents. However, retractions and self-correcting the literature at large are not factors influencing grant review, and dealing with retractions in reviewing grants is an open question for funders. (shrink)

We argue that thoughts are structures of concepts, and that concepts should be individuated by their origins, rather than in terms of their semantic or epistemic properties. Many features of cognition turn on the vehicles of content, thoughts, rather than on the nature of the contents they express. Originalism makes concepts available to explain, with no threat of circularity, puzzling cases concerning thought. In this paper, we mention Hesperus/Phosphorus puzzles, the Evans-Perry example of the ship seen through different windows, and (...) Mates cases, and we believe that there are many additional applications. (shrink)

Koriat & Goldsmith propose that the correspondence metaphor captures the essence of everyday memory research. We suggest that correspondence is often not at issue because objective assessments of everyday events are frequently lacking. In these cases, other questions arise, such as how individuals evaluate the validity of memories and the significance they attach to those evaluations.

Drawing on signaling theory, we suggest that a supplier’s enforcement of ethical codes sends signals about the supplier that affect a buyer’s decision to continue their commitment to the supplier. We then draw on side-bet theory to hypothesize how switching costs influence the importance of a supplier’s enforcement of ethical codes in predicting a buyer’s continuance commitment to a supplier. We empirically test our model with data from 158 purchasing managers across three manufacturing industries. Results confirm the connection between ethical (...) code enforcement and continuance commitment, but suggest that a supplier’s enforcement of ethical codes matter less when switching suppliers is perceived as too costly.
