Despite the proliferation of research on ethical leadership, there remains a limited understanding of how specifically the assumingly moral component of this leadership style affects employee behavior. Taking an identity perspective, we integrate the ethical leadership literature with research on the dynamics of the moral self-concept to posit that ethical leadership will foster a sense of moral identity among employees, which then inspires followers to adopt more ethical actions, such as increased organization citizenship behavior. We further argue that these identity (...) effects should be more pronounced when leaders are perceived to be group prototypical, as their actions then speak louder to followers’ sense of identity. Two studies—a scenario experiment with 138 participants and a field study with 225 employees—provided support for our hypothesized moderated mediation model. Perceived ethical leadership positively affected OCB via followers’ moral identity but only under conditions of high perceived leader group prototypicality. We discuss how the identity pathway of ethical leadership can facilitate novel theorizing about moral transference. Our findings also suggest that, when hiring external ethical leaders or training internal managers, practitioners are well advised to consider that these individuals may only be effective in morally transforming followers when they are perceived as prototypical for the group.

Cyclic adenosine monophosphate (cAMP) and cAMP‐dependent protein kinase A (PKA) are evolutionary conserved molecules with a well‐established position in the complex network of signal transduction pathways. cAMP/PKA‐mediated signaling pathways are implicated in many biological processes that cooperate in organ development including the motility, survival, proliferation and differentiation of epithelial cells. Cell surface polarity, here defined as the anisotropic organisation of cellular membranes, is a critical parameter for most of these processes. Changes in the activity of cAMP/PKA elicit a variety of (...) effects on intracellular membrane dynamics, including membrane sorting and trafficking. One of the most intriguing aspects of cAMP/PKA signaling is its evolutionary conserved abundance on the one hand and its precise spatial–temporal actions on the other. Here, we review recent developments with regard to the role of cAMP/PKA in the regulation of intracellular membrane trafficking in relation to the dynamics of epithelial surface domains.

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)

Theorists, historians, and artists address the precarious futurity of the notion of the future. Not long ago, a melancholic left and a manic neoliberalism seemed to arrive at an awkward consensus: the foreclosure of futurity. Whereas the former mourned the failure of its utopian project, the latter celebrated the triumph of a global marketplace. The radical hope of realizing a singularly different, more equitable future displaced by a belief that the future had already come to pass, limiting post-historical society to (...) an uneventful life of endless accumulation. Today, amidst an abundance of neofuturisms, posthumanisms, futurologies, speculative philosophies and accelerationist scenarios, there is as well an expanding awareness of a looming planetary catastrophe driven by the extractionist logic of capitalism. Despite this return to the future, the temporal horizon of our present moment is perhaps more aptly characterized by the “shrinking future” of just-in-time production, risk management, high-frequency trading, and the futures market. In Futurity Report, theorists, historians, and artists address the precarious futurity of the notion of the future itself.

Humans’ indigenous microbes strongly influence organ functions in an age‐ and diet‐dependent manner, adding an important dimension to aging biology that remains poorly understood. Although age‐related differences in the gut microbiota composition correlate with age‐related loss of organ function and diseases, including inflammation and frailty, variation exists among the elderly, especially centenarians and people living in areas of extreme longevity. Studies using short‐lived as well as nonsenescent model organisms provide surprising functional insights into factors affecting aging and implicate attenuating effects (...) of microbes as well as a crucial role for certain transcription factors like forkhead box O. The unexpected beneficial effects of microbes on aged animals imply an even more complex interplay between the gut microbiome and the host. The microbiome constitutes the major interface between humans and the environment, is influenced by biosocial stressors and behaviors, and mediates effects on health and aging processes, while being moderated by sex and developmental stages.

Collective migration is a key process that is critical during development, as well as in physiological and pathophysiological processes including tissue repair, wound healing and cancer. Studies in genetic model organisms have made important contributions to our current understanding of the mechanisms that shape cells into different tissues during morphogenesis. Recent advances in high‐resolution and live‐cell‐imaging techniques provided new insights into the social behavior of cells based on careful visual observations within the context of a living tissue. In this review, (...) we will compare Drosophila testis nascent myotube migration with established in vivo model systems, elucidate similarities, new features and principles in collective cell migration.

This monograph is a detailed study, and systematic defence, of the Growing Block Theory of time (GBT), first conceived by C.D. Broad. The book offers a coherent, logically perspicuous and ideologically lean formulation of GBT, defends it against the most notorious objections to be found in the extant philosophical literature, and shows how it can be derived from a more general theory, consistent with relativistic spacetime, on the pre-relativistic assumption of an absolute and total temporal order. -/- The authors devise (...) axiomatizations of GBT and its competitors which, against the backdrop of a shared quantified tense logic, significantly improves the prospects of their comparative assessment. Importantly, neither of these axiomatizations involves commitment to properties of presentness, pastness or futurity. The authors proceed to address, and defuse, a number of objections that have been marshaled against GBT, including the so-called epistemic objection according to which the theory invites skepticism about our temporal location. The challenge posed by relativistic physics is met head-on, by replacing claims about temporal variation by claims about variation across spacetime. -/- The book aims to achieve the greatest possible rigor. The background logic is set out in detail, as are the principles governing the notions of precedence and temporal location. The authors likewise devise a novel spacetime logic suited for the articulation, and comparative assessment, of relativistic theories of time. The book comes with three technical appendices which include soundness and completeness proofs for the systems corresponding to GBT and its competitors, in both their pre-relativistic and relativistic forms. -/- The book is primarily directed at researchers and graduate students working on the philosophy of time or temporal logic, but is of interest to metaphysicians and philosophical logicians more generally.

In a recent article, Sabine Müller, Merlin Bittlinger, and Henrik Walter launch a sweeping attack against what they call the "personal identity debate" as it relates to patients treated with deep brain stimulation (DBS). In this critique offered by Müller et al., the so-called personal identity debate is said to: (a) be metaphysical in a problematic way, (b) constitute a threat to patients, and (c) use "vague" and "contradictory" statements from patients and their families as direct evidence for metaphysical theories. (...) In this response, I critically evaluate Müller et al.'s argument, with a special focus on these three just-mentioned aspects of their discussion. My conclusion is that Müller et al.'s overall argument is problematic. It overgeneralizes criticisms that may apply to some, but certainly not to all, contributions to what they call the personal identity-debate. Moreover, it rests on a problematic conception of what much of this debate is about. Nor is Müller et al.'s overall argument fair in its assessment of the methodology used by most participants in the debate. For these reasons, we should be skeptical of Müller et al.'s claim that the "personal identity debate" is a "threat to neurosurgical patients". (shrink)

As an extension of the well-known Action Description Language A introduced by M. Gelfond and V. Lifschitz [8] C. Baral and M. Gelfond recently defined the diafect AC which supports the description of concurrent actions [1]. Also, a sound but incomplete encoding of AC by means of an extended logic program was presented there. In this paper, we work on interpretations of contradictory inferences from partial action descriptions. Employing an interpretation different from the one implicitly used in AC, we present (...) a new dialect which allows to infer sound information from contradictory descriptions and to describe non-determinism and uncertainty. Furthermore, we give the first sound and complete encoding of AC, using equational logic programming, and extend it to as well. (shrink)

Multiple contraction (simultaneous contraction by several sentences) and iterated contraction are investigated in the framework of specified meet contraction (s.m.c.) that is extended for this purpose. Multiple contraction is axiomatized, and so is finitely multiple contraction (contraction by a finite set of sentences). Two ways to reduce finitely multiple contraction to contraction by single sentences are introduced. The reduced operations are axiomatically characterized and their properties are investigated. Furthermore, it is shown how iterated contraction can be reduced to single-step, single-sentence (...) contraction. However, in this framework the outcome of iterated contraction depends unavoidably on the order in which the inputs are received. This order-dependence makes it impossible to treat two inputs on an equal footing. Therefore it is often preferable to perform changes involving several pieces of information as multiple rather than iterated change. (shrink)

This chapter responds to criticismsmade in Volume 8 of this series, in reply to another chapter of that volume. The initial chapter resurrected the Growing Block Theory from its grave, devising a coherent formulation of it and arguing that its burial was premature. It aimed to show that GBT has the wherewithal to explain how we might easily come to know that we are living on the edge of reality posited by GBT. Braddon-Mitchell, in the reply, remained unconvinced. His objections (...) are addressed here. (shrink)

The Ethics of Human Enhancement: Understanding the Debate has two chief aims. These aims are to help readers understand the existing debate and to move the debate forward. The book consists of an introductory chapter by Alberto Giubilini and Sagar Sanyal (which lays out some prominent bioconservative objections to enhancement), eight essays grouped under the theme of "Understanding the Debate" (Section I), and eight devoted to "Advancing the Debate" (Section II). In this review, we offer brief summaries of each essay (...) and ask whether the book successfully advances the debate. (shrink)

We investigated, by means of the Reverse Correlation Task, visual representations of the culturally dominating group of local people held by sojourners as a function of their degree of cross-cultural adaptation. In three studies, using three different methods with three independent samples of sojourners and seven independent samples of Portuguese and US-American raters, we gathered clear evidence that poor adaptation goes along with more negative representations of locals. This indicates that sojourner adaptation is reflected, at a social-cognitive level, in the (...) valence of outgroup representations. (shrink)

In fungi, cell fusion between genetically unlike individuals triggers a cell death reaction known as the incompatibility reaction. In Podospora anserina, the genes controlling this process belong to a gene family encoding STAND proteins with an N‐terminal cell death effector domain, a central NACHT domain and a C‐terminal WD‐repeat domain. These incompatibility genes are extremely polymorphic, subject to positive Darwinian selection and display a remarkable genetic plasticity allowing for constant diversification of the WD‐repeat domain responsible for recognition of non‐self. Remarkably, (...) the architecture of these proteins is related to pathogen‐recognition receptors ensuring innate immunity in plants and animals. Here, we hypothesize that these P. anserina incompatibility genes could be components of a yet‐unidentified innate immune system of fungi. As already proposed in the case of plant hybrid necrosis or graft rejection in mammals, incompatibility could be a by‐product of pathogen‐driven divergence in host defense genes. (shrink)

In Sven Bernecker’s excellent new book, Memory, he proposes an account of what we might call the “metasemantics” of memory: the conditions that determine the contents of the mental representations employed in memory. Bernecker endorses a “pastist externalist” view, according to which the content of a memory-constituting representation is fixed, in part, by the “external” conditions prevalent at the time of the tokening of the original representation. Bernecker argues that the best version of a pastist externalism about memory contents (...) will have the result that there can be semantically-induced memory losses in cases involving unwitting “world-switching”. The burden of this paper is to show that Bernecker’s argument for this conclusion does not succeed. My arguments on this score have implications for our picture of mind-world relations, as these are reflected in a subject’s attempts to recall her past thoughts. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Moral Philosophy on the Threshold of ModernityDouglas LangstonJill Kraye and Risto Saarinen, editors. Moral Philosophy on the Threshold of Modernity. New Synthese Historical Library, 57. Dordrecht: Springer, 2005. Pp. vi + 340. Cloth, €139.10.This is a collection of fifteen essays from a 2001 workshop, "Late Medieval and Early Modern Ethics and Politics," funded by the European Science Foundation as part of a network of meetings on Early Modern (...) Thought. The editors intend the volume to reflect current historical and philosophical scholarship about the moral thought of the fifteenth and sixteenth centuries. It is arranged into three sections, reflecting three different themes: 1. Scholastics and Neo-Scholasticism; 2. Theories of Human Rights and Dominion; 3. Reformers and Humanists. These themes demonstrate "the range and diversity of moral philosophy between 1400 and 1600" (5), and show "the continuity between late medieval and early modern thought" (2).The collection achieves these two aims. Essays treat such divergent schools of moral thought as Aristotelian scholasticism, casuistry, probabilism, post-Reformation Christian ethics, and neo-Stoicism. They discuss such figures as Suarez, Lessius, Gerson, Luther, Melanchthon, Daneau, Vives, and Muret. Each essay focuses on a figure or issue in the early modern period and connects the topic to relevant medieval material. So, for example, Risto Saarinen's "Ethics in Luther's Theology: The Three Orders" relates Luther's views of the three estates—church (ecclesia), household (œconomia), state (politia)—to the division medieval Aristotelian ethicists made between Aristotle's individual and social ethics.If one of the strengths of this collection is the range and diversity of material treated, it is also its principal weakness. It is difficult to imagine that most readers will be interested in the essays of all three sections. As the titles of the sections suggest, readers interested in the views of humanists or reformers will look to the essays of the third section primarily. Those who are interested in backgrounds to modern theories about human rights and property will look to the second section. And the first section will appeal to those interested in scholasticism, probabilism, and casuistry. This is not to suggest that the three sections [End Page 475] are unconnected. In fact, there are very strong connections between the first and second sections in showing how certain key notions of modern thought develop in the period from 1400 to 1600. And some of the essays of the third section present the views of certain reformers and humanists on related issues.In the second section, Roberto Lambertini's "Poverty and Power: Franciscans in Later Medieval Political Thought" and Virpi Mäkinen's "The Franciscan Background of Early Modern Rights Discussion: Rights of Property and Subsistence" argue that concepts of individual rights and property—hallmarks of modern thought—emerge in the controversies surrounding Franciscan poverty. Questions about whether property or only its use is natural are connected to issues about individual rights of subsistence, particularly whether Franciscan poverty is against the inalienable natural right of self-preservation everyone possesses. In "Conrad Summenhart on Natural Rights," Jussi Varkemaa shows how Summenhart used Jean Gerson's discussions of jus to argue that a person is dominus (lord) of his own person and can voluntarily enslave himself to another without violating his natural right of liberty. Issues about individual rights are also at play in several essays in the first section of the book. Sven K. Knebel's "Casuistry and the Early Modern Paradigm Shift in the Notion of Charity" discusses how an innocent person is to behave under torture. At issue is whether an innocent should suffer death by maintaining his innocence or preserve his life by sacrificing his reputation through lying. This conflict led to discussions about the status of one's reputation—is it the property of an individual?—as well as the nature of the right of self-preservation. Similarly, Rudolf Schüssler's "On the Anatomy of Probabilism" discusses how the "possidentis principle" became a cornerstone of probabilism at the end of the sixteenth century. According to this principle, "a bona fide possessor of a thing may not be deprived of it as long as the unlawfulness of his possession is not significantly established... (shrink)

Justification as Ignorance offers an original account of epistemic justification as both non-factive and luminous, vindicating core internalist intuitions without construing justification as an internal condition knowable by reflection alone. Sven Rosenkranz conceives of justification, in its doxastic and propositional varieties, as a kind of epistemic possibility of knowing and of being in a position to know. His account contrasts with recent alternative views that characterize justification in terms of the metaphysical possibility of knowing. Instead, he develops a suitable (...) non-normal multi-modal epistemic logic for knowledge and being in a position to know that respects the finding that these notions create hyperintensional contexts. He also defends his conception of justification against well-known anti-luminosity arguments, shows that the account allows for fruitful applications and principled solutions to the lottery and preface paradoxes, and provides a metaphysics of justification and its varying degrees of strength that is compatible with core assumptions of the knowledge-first approach and disjunctivist conceptions of mental states.

De Interpretatione is among Aristotle's most influential and widely read writings; C. W. A. Whitaker presents the first systematic study of this work, and offers a radical new view of its aims, its structure, and its place in Aristotle's system. He shows that De Interpretatione is not a disjointed essay on ill-connected subjects, as traditionally thought, but a highly organized and systematic treatise on logic, argument, and dialectic.

Reuben Hersh confided to us that, about forty years ago, the late Paul Cohen predicted to him that at some unspecified point in the future, mathematicians would be replaced by computers. Rather than focus on computers replacing mathematicians, however, our aim is to consider the (im)possibility of human mathematicians being joined by “artificial mathematicians” in the proving practice—not just as a method of inquiry but as a fellow inquirer.

Could groups ever be an understanding subject (an epistemic agent ascribed with understanding) or should we keep our focus exclusively on the individuals that make up the group? The way this paper will shape an answer to this question is by starting from a case we are most willing to accept as group understanding, then mark out the crucial differences with an unconvincing case, and, ultimately, explain why these differences matter. In order to concoct the cases, however, we need to (...) elucidate what it means to be attributed with understanding and what makes up an epistemic agent. I shall argue that it is abilities, above all, that guide our attributions of understanding. While it is true that understanding must go beyond single acts, this is not going beyond as in going behind them (to private occurrences which are impossible to discern and don’t themselves contribute anything of value), but beyond as in considering what people could and would do: their discernable and valuable abilities. To conceptualize whom the abilities belong to, I will specify what it means to be an epistemic agent. I shall argue that it is being a successful target of the epistemic stance. The epistemic stance (heavily inspired by Dennett’s intentional stance) forms an instrumental abstraction by attributing epistemic properties (i.e., beliefs, epistemic aims, problem-solving tactics) to an entity to explain or predict its behavior. Macro-systematicity (a higher-level pattern which a theory can exploit) is what makes the epistemic stance’s abstraction an explanatory powerful one (regardless of how that macro-systematicity is realized) and emergence (the lack of a straightforward mapping-relation between the micro and the macro) is what makes its power unique to a particular level of explanation. To end, I suggest two kinds of mapping-relations and walk through the shift from reducibility to emergence. (shrink)

How do we ascribe subjective probability? In decision theory, this question is often addressed by representation theorems, going back to Ramsey (1926), which tell us how to define or measure subjective probability by observable preferences. However, standard representation theorems make strong rationality assumptions, in particular expected utility maximization. How do we ascribe subjective probability to agents which do not satisfy these strong rationality assumptions? I present a representation theorem with weak rationality assumptions which can be used to define or measure (...) subjective probability for partly irrational agents. (shrink)
