Earth system science (ESS) has identified worrying trends in the human impact on fundamental planetary systems. In this conceptual article, we discuss the implications of this research for business schools and management education (ME). We argue that ESS findings raise significant concerns about the relationship between business and nature and, consequently, a radical reframing is required to embed economic and social activity within the global sustainability of natural systems. This has transformative implications for ME. To illustrate this reframing, we apply (...) the ESS lenses of social-ecological interdependence, multiscalar relations, environmental governance, and environmental values to the ME functional domains of institutional purpose, social context and engagement, pedagogical practice, curricular design, and research focus. Our work contributes to the literature on business education for sustainability and the business-society-nature nexus. We explore and apply key ESS findings and concepts, discuss normative implications of these ideas, and offer guidance on transformational pathways for business schools and ME. (shrink)

This book provides a compositional, truth-conditional, crosslinguistic semantics for evidentiality, the linguistic encoding of the source of information on which a statement is based. Central to the proposed theory is the distinction between what propositional content is at-issue and what content is not-at-issue. Evidentials contribute not-at-issue content, and can affect the level of commitment a sentence makes to the main proposition, contributed by sentential mood. In this volume, Sarah Murray builds on recent work in the formal semantics of evidentials (...) and related phenomena, and proposes a semantics that does not appeal to separate dimensions of illocutionary meaning. Instead, she argues that all sentences make three contributions: at-issue content, not-at-issue content, and an illocutionary relation. At-issue content is presented and made available for subsequent anaphora, but is not directly added to the common ground; not-at-issue content directly updates the common ground; and the illocutionary relation uses the at-issue content to impose structure on the common ground, which, depending on the clause type, can trigger further updates. 0The analysis is supported by extensive empirical data from Cheyenne, drawn from the author's own fieldwork, as well as from English and a variety of other languages.

A number of sociologists have identified the emergence of a ‘new paradigm’ of health, based on the principle that the National Health Service should seek to prevent ill-health rather than simply treat the sick. The sociology of health promotion that has emerged over the past 15 years has contributed to debates about risk, lifestyle and consumerism, but the gendered nature of what some refer to as the ‘new morality of health’, and in particular its urging of feminine attributes, has largely (...) been neglected. This article provides a critical examination of the ‘new paradigm’ of health and its relationship to femininity. I suggest that femininity involves a certain attitude to the body that we also find in current health policy, and cultural representations of health more generally: that the body is essentially uncontrollable (yet something we should seek to control, as a matter of virtue), that it is a good in and of itself, and that it is synonymous with the self.

Philosophers of literature direct their studies to the moral, cognitive, and emotional aspects of our involvement with fiction. In spite of this, they rarely engage works of popular fiction. In this paper I use The Da Vinci Code as a case study of the impact of popular fiction on readers in terms of these three areas. Although this book will never be considered good literature, its impact is far reaching. l address concerns dealing with the fiction/non-fiction distinction as weIl as (...) issues with history, accuracy, and falsehoods. I flesh out the issues The Da Vinci Code brings up and argue that it, along with other works of popular fiction (Oprah’s book club for example), might be taken more seriously by philosophers of literature.

Although the dynamic field model predicts infants' perseverative behavior in the context of the A-not-B manual search task, it does not account for infant perseveration in other contexts. An alternative cognitive capacity explanation for perseveration is more parsimonious. It accounts for the graded nature of perseverative responses and perseveration in different contexts.

Examined as an isolated situation, and through the lens of a rare and feared disease, Mr. Duncan's case seems ripe for second-guessing the physicians and nurses who cared for him. But viewed from the perspective of what we know about errors and team communication, his case is all too common. Nearly 440,000 patient deaths in the U.S. each year may be attributable to medical errors. Breakdowns in communication among health care teams contribute in the majority of these errors. The culture (...) of health care does not seem to foster functional, effective communication between and among professionals. Why? And more importantly, why do we not do something about it? (shrink)

Across cultures, people employ space to construct representations of time. English exhibits two deictic space–time metaphors: the “moving ego” metaphor conceptualizes the ego as moving forward through time and the “moving time” metaphor conceptualizes time as moving forward towards the ego. Earlier research investigating the psychological reality of these metaphors has shown that engaging in certain types of spatial-motion thinking may influence how people reason about events in time. More recently, research has shown that people’s interactions with cultural artifacts may (...) also influence their representations of time. Extending research on space–time mappings in new directions, three experiments investigated the role of cultural artifacts, namely calendars and clocks, in the interpretation of metaphorical expressions about time. Taken together, the results provide initial evidence that, in their interpretation of ambiguous metaphorical expressions about time, people automatically access and use spatial representations of absolute time, whereby moving forward in space corresponds with moving later in time. Moreover, asking participants to use a reverse space–time mapping causes interference, which is reflected through their temporal reasoning. (shrink)

In English, two deictic space-time metaphors are in common usage: the Moving Ego metaphor conceptualizes the ego as moving forward through time and the Moving Time metaphor conceptualizes time as moving forward toward the ego . Although earlier research investigating the psychological reality of these metaphors has typically examined spatial influences on temporal reasoning , recent lines of research have extended beyond this, providing initial evidence that personality differences and emotional experiences may also influence how people reason about events in (...) time . In this article, we investigate whether these relationships have force in real life. Building on the effects of individual differences in self-reported conscientiousness and procrastination found by Duffy and Feist , we examined whether, in addition to self-reported conscientiousness and procrastination, there is a relationship between conscientious and procrastinating behaviors and temporal perspective. We found that participants who adopted the Moving Time perspective were more likely to exhibit conscientious behaviors, while those who adopted the Moving Ego perspective were more likely to procrastinate, suggesting that the earlier effects reach beyond the laboratory.

In languages like English, reflexivity and reciprocity are expressed by distinct proforms. However, many languages, such as Cheyenne, express reflexivity and reciprocity with a single proform. In this paper I utilize Dynamic Plural Logic (van den Berg, 1996) to a draw a semantic parallel between reflexive and reciprocal anaphors in English. I propose that they contribute overlapping but distinct requirements on the relations introduced by transitive verbs, requirements which fully specify reflexivity and reciprocity. This parallel is then extended to Cheyenne (...) by appealing to underspecification. I propose the Cheyenne affix which expresses both reflexivity and reciprocity contributes only the shared requirement of the English anaphors. It is thus underspecified, not ambiguous. This accounts for its compatibility with both singular and plural antecedents as well as its variety of construals. (shrink)

There are a host of data privacy decisions we must make every day – and it is exceedingly difficult, if not impossible, for us to make meaningful decisions about all of them. In this thesis, I define, conceptualize, interrogate, and design for value-centered privacy decision making – that is, decisions that are focused on who we are and what we value – as a means of respecting and promoting user autonomy. To achieve this, this work utilizes philosophical theory to understand (...) value-centered privacy decisions and translates this theory into a system that promotes such decisions. In summary, this work has two major contributions. Firstly, I conceptualize and define value-centered privacy decision-making using a value-centered theory of autonomy. I explore how we can create the space for value-centered privacy decisions by applying the Four-Dimensional Theory of Self Governance (4DT). I first conceptualize privacy decisions in terms of these four dimensions – self-definition, self-realization, self-unification, and self-constitution – and explore existing data privacy challenges through this lens. In particular, I conceptualize notice fatigue in terms self-realization, self-unification, and self-constitution; a lack of relevant privacy controls in terms of self-realization and self-unification; and nudges in terms of self-realization and self-unification. I then present and discuss results from a mixed-methods investigation into how values are involved in privacy decisions – in particular, app choice. We found that they were related in a highly individualized, context specific manner, observing different values that were more relevant based on the app in question. This suggests that the value-privacy relationship is largely informed by individual preferences and understandings of values. However, the values of Use, Control, and Community were quite prevalent, with Use and Control in particular spanning contexts and individual participants. They were also frequently perceived as in conflict with each other. This suggests that these three values are the most relevant to consider when designing for value-centered privacy decisions. The participants’ experiences can also be explained using 4DT, providing empirical support for our conceptualization of value centered privacy. However, the study results also provide insights into how existing systems – such as surveillance capitalism and the attention economy – frustrate value centered privacy decisions. Secondly, I use the 4DT-based understanding of value-centered privacy decisions to establish the usability and effectiveness of the value-centered approach, designing a privacy assistant to help users make app choices that are in more accordance with their personal values. To inform the design of a smartphone assistant that creates this space for users, I examine an existing technology – personalized privacy assistants (PPAs) – using the 4DT lens. Using insights from this examination, I propose a value-centered, smartphone privacy assistant (VcPA) to help users make more value-centered decisions at one privacy decision point: smartphone app choices. This VcPA consists of three features: selective notices, exploratory notices, and a “suggest alternative apps” feature. I then present the results from testing a prototype VcPA system with users, serving as a proof-of concept that a value-centered privacy assistant, designed using privacy preferences and values, could help users when making privacy decisions such as choosing apps. In particular, we found that the VcPA prototype helped users download value-consistent apps, with the “suggest alternatives” feature especially well-received. We also identified places where the VcPA could be improved – for example, profiles could be improved by being made more customizable; VcPA notices could be made easier to understand; and the “suggest alternatives” feature could be more streamlined. This thesis lays the groundwork for future researchers to design systems that promote value-centered privacy decisions. To guide this future work, I lastly present prospective research avenues to advance the value-centered approach to data privacy decision-making. In particular, I discuss limitations of the studies in this work, including engagement with a wider range of demographic groups; touch upon how the identified VcPA improvements, such as improved VcPA profiles, might be accomplished; briefly explore the possibility of applying the value-centered understanding to other privacy contexts; and consider how both system-wide regulation and individual autonomy enhancing interventions, such as the VcPA, can empower us to shape a technological future based on our values.

On one view, the point of an assertion is to update the common ground (Stalnaker 1978, Karttunen 1974). On another, the point of an assertion is to propose an update to the com- mon ground (Groenendijk 2009, Mascarenhas 2009, and related work on the structure of discourse, e.g., Ginzburg 1996, Roberts 1996, Gunlogson 2001). In Murray (to appear), I merge these two views. I argue based on evidence from declarative sentences with eviden- tials that assertion has two components: what is (...) at-issue and what is not. The not-at-issue component of assertion is added directly to the common ground while the at-issue compo- nent is proposed to be added to the common ground. Here, I extend this analysis to yes/no questions in Cheyenne and their interaction with evidentials. I propose that the distinction between what is at-issue and what is not is also present in questions, and that it can be modeled in the same way. Specifically, both declarative and interrogative sentences make two contributions: they restrict and structure the common ground. The restriction is based on the not-at-issue component while the structuring relation is based on the at-issue component. (shrink)

In this fascinating book, Sarah Worth addresses from a philosophical perspective the many ways in which reading benefits us morally, socially and cognitively.

In this paper, I propose that the distinction between what is at-issue and what is not can be modeled as a distinction between two components of assertion. These two components affect the common ground in different ways. The at-issue component of an assertion, which is negotiable, is treated as a proposal to update the common ground. The not-at-issue component of an assertion, which is not negotiable, is added directly to the common ground. Evidence for this proposal comes from evidentials, which (...) I argue grammaticize this distinction. It has been observed that sentences with evidentials make both an ‘evidential’ and a ‘propositional’ contribution (Faller 2002, 2006, Matthewson et al. 2008). The evidential contribution is not directly challengeable or up for negotiation. In contrast, the propositional contribution, the ‘main point’ of the sentence, is directly challengeable and up for negotiation. I analyze these two contributions of evidentials as the not-at-issue component of assertion and the at-issue component of assertion, respectively. Supporting data comes from Cheyenne, a language with evidentials that are part of the illocutionary mood paradigm. (shrink)

Mastery imagery (i.e., images of being in control and coping in difficult situations) is used to regulate anxiety. The ability to image this content is associated with trait confidence and anxiety, but research examining mastery imagery ability's association with confidence and anxiety in response to a stressful event is scant. The present study examined whether trait mastery imagery ability mediated the relationship between confidence and anxiety, and the subsequent associations on performance in response to an acute psychological stress. Participants (N= (...) 130; 55% male;Mage= 19.94 years;SD= 1.07 years) completed assessments of mastery imagery ability and engaged in a standardized acute psychological stress task. Immediately prior to the task, confidence, cognitive and somatic anxiety intensity, and interpretation of anxiety symptoms regarding the task were assessed. Path analyses supported a model whereby mastery imagery ability mediated the relationship between confidence and cognitive and somatic anxiety interpretation. Greater mastery imagery ability and confidence were both directly associated with better performance on the stress task. Mastery imagery ability may help individuals experience more facilitative anxiety and perform better during stressful tasks. Improving mastery imagery ability by enhancing self-confidence may help individuals successfully cope with anxiety elicited during stressful situations. (shrink)

In the current post-GDPR landscape, privacy notices have become ever more prevalent on our phones and online. However, these notices are not well suited to their purpose of helping users make informed decisions. I suggest that instead of utilizing notice to elicit informed consent, we could repurpose privacy notices to create the space for more meaningful, value-centered user decisions. Value-centered privacy decisions, or those that accurately reflect who we are and what we value, encapsulate the intuitive role of personal values (...) in data privacy decisions. To explore how we could design for such decisions, I utilize Suzy Killmister’s Four-Dimensional Theory of Autonomy (4DT) to operationalize value-centered privacy decisions. I then utilize 4DT to help design a system—called a value-centered privacy assistant (VcPA)—that could help create the space for value-centered data privacy decisions using privacy notices. Using this 4DT lens, I further assess the degree that an existing technology, personalized privacy assistants (PPAs), use notices in a manner that allows for value-centered decision-making. I lastly utilize insights from the PPA assessment to inform the design of a VcPA, concluding that a VcPA could utilize notices to assist users in value-centered app selection and in other data privacy decisions.

Treatments for students with problematic levels of music performance anxiety commonly rely on approaches in which students are referred to psychotherapists or other clinical professionals for individual care that falls outside of their music training experience. However, a more transdisciplinary approach in which MPA treatment is effectively integrated into students’ training in music/performing arts colleges by teachers who work in consultation with clinical psychologists may prove more beneficial, given the resistance students often experience toward psychotherapy. Training singing teachers, and perhaps (...) music teachers at large, to use an evidence-based coaching strategy like Acceptance and Commitment Coaching to directly manage students’ MPA is one such approach. Building on the work of a previous study in which ACC was administered by a singing teacher to a musical theatre student with problematic MPA, we piloted the effectiveness of a six-session, group ACC course for a sample of performing arts students with MPA related to vocal performances, using a mixed-methods design. The coach here was also a singing teacher without a clinical background, and her training in ACC by a clinical psychologist was of a similar duration as the previous teacher’s. Similar to the musical theatre student, the students reported being significantly less fused with their MPA-related cognitions, more accepting of their MPA-related physiological symptoms, and more psychologically flexible while performing in general, and these improvements were maintained after 3 months. Furthermore, they appeared to lower their shame over having MPA and change how they thought in relation to one another. Of note, these improvements were similar to those shown by seven vocal students with MPA after they received Acceptance and Commitment Therapy from a clinical psychologist, but with larger reductions in shame and better acceptance of MPA, which suggests a non-clinical, group ACC intervention that includes supportive discussions to normalize MPA and challenges attempts to control it may be more helpful than individual psychotherapy. These results are promising and indicate a brief training in ACC may be sufficient for singing teachers to provide significant benefit for students with problematic MPA. (shrink)

Many languages grammatically mark evidentiality, i.e., the source of information. In assertions, evidentials indicate the source of information of the speaker while in questions they indicate the expected source of information of the addressee. This dissertation examines the semantics and pragmatics of evidentiality and illocutionary mood, set within formal theories of meaning and discourse. The empirical focus is the evidential system of Cheyenne (Algonquian: Montana), which is analyzed based on several years of fieldwork by the author.

Previous research with video game play and moral development with adolescents, found both positive and negative relationships. This study aimed to extend this research to explore moral development and video game play with University students. One hundred and thirty-five undergraduate students (M = 20.29 SD = 2.70) took part in an online survey. The results suggested higher moral reasoning for participants who described themselves as gamers and those which do not players, compared to the those who play but do not (...) identify as gamers. It was suggested that males had higher moral scores and more mature reasoning than females. The results of a regression analysis suggested that there were no significant predictors for moral development from either game play or the demographic variables. The findings suggest that moral development could be less influenced by sex, age, and video game play factors such as video game content and amount of game play, than was previously thought.

Nuclear speckles are eukaryotic nuclear bodies enriched in splicing factors. Their exact purpose has been a matter of debate. The different proposed roles of nuclear speckles are reviewed and an additional layer of function is put forward, suggesting that by accumulating splicing factors within them, nuclear speckles can buffer the nucleoplasmic levels of splicing factors available for splicing and thereby modulate splicing rates. These findings build on the already established model that nuclear speckles function as a storage/recycling site for splicing (...) factors. Many studies have demonstrated proximity between nuclear speckles and sites of active transcription, suggesting that this juxtaposition can enhance the rates of gene expression. It is found that nuclear speckle disassembly increases splicing factor availability in the nucleoplasm, leading to an increase in splicing rates and faster release of nascent transcripts from the gene after transcription. Altogether, this era in which genomic and imaging approaches are applied to study nuclear organization has expanded the outlook on the possible roles of nuclear speckles. (shrink)

Language and culture endow humans with access to conceptual information that far exceeds any which could be accessed by a non-human animal. Yet, it is possible that, even without language or specific experiences, non-human animals represent and infer some aspects of similarity relations between objects in the same way as humans. Here, we show that monkeys’ discrimination sensitivity when identifying images of animals is predicted by established measures of semantic similarity derived from human conceptual judgments. We used metrics from computer (...) vision and computational neuroscience to show that monkeys’ and humans’ performance cannot be explained by low-level visual similarity alone. The results demonstrate that at least some of the underlying structure of object representations in humans is shared with non-human primates, at an abstract level that extends beyond low-level visual similarity. Because the monkeys had no experience with the objects we tested, the results suggest that monkeys and humans share a primitive representation of object similarity that is independent of formal knowledge and cultural experience, and likely derived from common evolutionary constraints on object representation.

This paper discusses three potential varieties of update: updates to the common ground, structuring updates, and updates that introduce discourse referents. These different types of update are used to model different aspects of natural language phenomena. Not-at-issue information directly updates the common ground. The illocutionary mood of a sentence structures the context. Other updates introduce discourse referents of various types, including propositional discourse referents for at-issue information. Distinguishing these types of update allows a unified treatment of a broad range of (...) phenomena, including the grammatical evidentials found in Cheyenne (Algonquian) as well as English evidential parentheticals, appositives, and mood marking. An update semantics that can formalize all of these varieties of update is given, integrating the different kinds of semantic contributions into a single representation of meaning. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Peaceful Persuasion: The Geopolitics of Nonviolent RhetoricSarah E. DempseyPeaceful Persuasion: The Geopolitics of Nonviolent Rhetoric. Ellen W. Gorsevski. Albany: State University of New York Press, 2004.pp. 262. $55.00, hardcover.The overriding emphasis on violence, militarization, and retribution within current geopolitical contexts demands that we acquire greater understandings of nonviolent communicative practices. In Peaceful Persuasion, author Ellen Gorsevski, Professor of English and Communication at Oregon State University, argues that nonviolent (...) rhetoric tends to be ignored by scholars—that its methods, strategies, and impacts are often passed over and that nonviolence is often framed as hopelessly utopian, unrealistic, and ineffective. Gorsevski situates her study of nonviolent rhetoric less within its humanistic and religious inheritance, drawing instead on a contrast with existing models of rhetoric. As a strategy for rhetorical and political action, Gorsevski takes nonviolence to be instructive of new ways to reconfigure both rhetorical studies and social movement strategy.It is important to note that Gorsevski's need to study peaceful means of relating to others is driven as much by a love of rhetorical theory as by a passion for translating an understanding of nonviolent rhetoric into strategies for activists. As such, this book provides a solid introduction to rhetorical theory, including an appendix on the connection between rhetoric and nonviolence that details what activists have to gain from each. In addition, instructors will find useful a chapter on the specifics of incorporating nonviolence into speech communication classrooms.Peaceful Persuasion's greatest contribution to rhetorical studies is the careful drawing out of the many ways that a rhetorical take on nonviolence has become increasingly necessary. To make this solid case, Gorsevski draws on four very diverse case studies of nonviolent rhetoric. In a move that is both surprising and refreshing, Gorsevski's case studies do more than provide exemplars of how critics may read nonviolence as a powerful rhetorical strategy; each helps to further delineate the key characteristics of what has been, until now, a relatively undefined area of rhetorical action.Gorsevski's gift to her readers is the ability to demonstrate the rich subtleties of nonviolence through very different contexts. The case studies [End Page 89] draw from such different sources that at first seem disorienting. Upon reflection, it becomes clearer that they greatly complicate our notions of nonviolence, redressing the disservices of previous bleary analyses that configured nonviolence only by its lack of violence rather than according to its fruitful range of seemingly contradictory strategies. The cavernous distances each study crosses illuminate the multiplicity of forms, meanings, and strategies that nonviolence may take. As such, any definition of nonviolence that I may provide in this short review does a serious disservice to the depth that Gorsevski creates through her sometimes disjointed case studies.The case studies serve at least dual purposes, as each provides an analysis that extends our understandings of nonviolence in action as it also offers instructive mini-lessons for the further development of rhetorical studies. In the first case study, Gorsevski provides a contextualized analysis of critics' interpretations of the film The Spitfire Grill, which she shows to be reflective of the "predominantly accepting orientation that rhetoric and film critics hold for the idea that humans are characterized by "innate aggression" and violence" (68). For Gorsevski, this study demonstrates that nonviolence as a lens can be applied to a range of texts just as well as any other approach to rhetoric. Gorsevski moves her analysis of nonviolent rhetoric into the geopolitical realm for her study of President of Macedonia Kiro Gligorov's historic first speech before the United Nations. She takes his speech as evidence of the usefulness of pragmatic nonviolence, which entails "noncooperation or defiance of political adversaries in order to decry a perceived injustice" (72). Gligorov's speech illustrates that nonviolence and violence are best seen less as equivalent than, rather, as operating on a sliding scale. For Gorsevski, successful use of pragmatic nonviolence may even include a measure of violence as long as it serves to reduce the escalation of further strife.Next Gorsevski explores the visual rhetoric of the gendered body of Burmese activist and Nobel Peace Prize winner Aung San Suu Kyi to show...

Parts and wholes come in an infinite variety, but in each instance something, namely relations, joins the parts together to make them into a whole rather than an Aristotelian "heap." The ontological status of relations is the subject of this dissertation. ;The question of whether relations are real presupposes some method of determining what is real. A modified version of Whitehead's ontological principle, or the idea that only real things can have effects on other things, serves as the test of (...) the reality. If any effects result from a whole but not from a collection of parts, then a whole differs from its parts and relations are real. Such effects can manifest themselves in two ways: parts themselves may somehow be affected by being joined into a whole or some new property may emerge with a whole that cannot be attributed to the parts taken separately. If one discovers either type of effect, then relations are real. ;The first section of the dissertation is an historical examination on the question of the reality of the relations. In the first chapter, the positions of Hume, Parmenides and Whitehead are considered but ultimately rejected. The second chapter examines the positions of Aristotle and Wittgenstein, thinkers for whom relations are in some cases real, while the third examines Plato's idea on relations. ;In the fourth chapter, a distinction between two types of relations is drawn. The difference between these relations is found in whether or not the parts joined are affected by being in a whole. Static relations are those which join parts into a whole without affecting those parts, while parts joined by dynamic relations are affected by being in a whole. Both static and dynamic wholes possess emergent properties which come into being only when parts are joined into wholes. ;The second section focuses on the consequences of the reality of relations in philosophy, specifically in ethics, logic and the philosophy of space and time.

In this paper, I discuss the quantificational variability of Cheyenne indeterminates: the variety of interpretations they can receive and the grammatical contexts that condition these interpretations. Building on analyses of indeterminates in other languages, such as Kratzer and Shimoyama (2002), I present a Hamblin-style analysis of Cheyenne indeter- minates. The proposal builds on the analysis of declaratives and interrogatives argued for in Murray (2010). This analysis can account for the quantificational variability of indeterminates in the scope of propositional operators as (...) well as the scope of illocutionary mood markers. The analysis is formalized in an independently motivated update semantics (Update with Centering, Bittner 2011), which automatically provides the required alternatives. (shrink)

The purpose of this paper is to review critically Julian Savulescu's principle of 'Procreative Beneficence,' which holds that prospective parents are morally obligated to select, of the possible children they could have, those with the greatest chance of leading the best life. According to this principle, prospective parents are obliged to use the technique of pre-implantation genetic diagnosis (PGD) to select for the 'best' embryos, a decision that ought to be made based on the presence or absence of both disease (...) traits and non-disease traits such as intelligence. While several articles have been written in response to Savulescu's principle, none has systematically explored its philosophical underpinnings to demonstrate where it breaks down. In this paper I argue that the examples that Savulescu employs to support his theory in fact fail to justify it. He presents these examples as analogous to PGD, when in fact they differ from it in subtle but morally relevant ways. Specifically, Savulescu fails to acknowledge the fact that his examples evoke deontological and virtue ethics concerns that are absent in the context of PGD. These differences turn out to be crucial, so that, in the end, the analogies bear little support for his theory. Finally, I lay out the implications of this analysis for reproductive ethics.

Most, if not all, psychologists have served as teaching or research assistants during graduate school, been instructed by teaching assistants, or both. As both faculty and students themselves, graduate assistants are faced with several dilemmas for which they typically have little preparation or guidance. These issues are explored in the context of the existing literature on multiple relationships in academic settings. Recommendations are made for graduate assistants, their faculty supervisors or mentors, and administrators to proactively address and confront these challenges (...) in a manner consistent with the profession of psychology's ethics code and to minimize the potential for harm to those we are entrusted to teach.

Over the course of development, children acquire adult-like thinking about social categories such as race, which in turn informs their perceptions, attitudes, and behavior. However, children’s developing perceptions of race have been understudied particularly with respect to their potential influence on cross-race egalitarianism. Specifically, the acquisition of racial constancy, defined as the perception that race is a concrete and stable category, has been associated with increased awareness of racial stereotypes and group status differences. Yet, little work has investigated behavioral outcomes (...) stemming from the acquisition of racial constancy beliefs. Here, we investigate whether the presence or absence of racial constancy beliefs differentially predicts inequality aversion with racial ingroup versus outgroup members for young children. White children ( N = 202; ages 3–8) completed three sticker resource-allocation games with either a White or a Black partner shown in a photograph, after which racial constancy was measured. Results revealed that the acquisition of racial constancy interacted with partner race to predict inequality aversion outcomes in one game; however, age and gender also exerted strong effects.

In aging humans, aerobic exercise interventions have been found to be associated with more positive or less negative changes in frontal and temporal brain areas, such as the anterior cingulate cortex (ACC) and hippocampus, relative to no-exercise control conditions. However, individual measures such as gray-matter (GM) probability may afford less reliable and valid conclusions about maintenance or losses in structural brain integrity than a latent construct based on multiple indicators. Here, we established a latent factor of GM structural integrity based (...) on GM probability assessed by voxel-based morphometry, magnetization transfer saturation, and mean diffusivity. Based on this latent factor, we investigated changes in structural brain integrity during a six-month exercise intervention in brain regions previously reported in studies using volumetric approaches. Seventy-five healthy, previously sedentary older adults aged 63–76 years completed an at-home intervention study in either an exercise group (EG;n= 40) or in an active control group (ACG;n= 35). Measures of peak oxygen uptake (VO2peak) taken before and after the intervention revealed a time-by-group interaction, with positive average change in the EG and no reliable mean change in the ACG. Significant group differences in structural brain integrity changes were observed in the right and left ACC, right posterior cingulate cortex (PCC), and left juxtapositional lobule cortex (JLC). In all instances, average changes in the EG did not differ reliably from zero, whereas average changes in the ACG were negative, pointing to maintenance of structural brain integrity in the EG, and to losses in the ACG. Significant individual differences in change were observed for right ACC and left JLC. Following up on these differences, we found that exercising participants with greater fitness gains also showed more positive changes in structural integrity. We discuss the benefits and limitations of a latent-factor approach to changes in structural brain integrity, and conclude that aerobic fitness interventions are likely to contribute to brain maintenance in old age.
