Agouti expression during the middle portion of the mouse hair growth cycle induces melanocytes to synthesize yellow instead of black pigment, generating black hairs with a yellow band. Dominant agouti alleles increase the amount of yellow pigment in the coat and are associated with pleiotropic effects including obesity, diabetes and increased tumor susceptibility. Four dominant agouti alleles (Aiapy, Aiy, Asy and Avy) were recently shown to result from insertions that cause ubiquitous expression of chimeric transcripts encoding a wild‐type agouti protein(1,2). (...) Three insertions were identified as intracisternal A‐particles, which helps explain the variable coat colors and parental imprinting effects associated with some dominat agouti alleles.

According to pancomputationalism, all physical systems – atoms, rocks, hurricanes, and toasters – perform computations. Pancomputationalism seems to be increasingly popular among some philosophers and physicists. In this paper, we interpret pancomputationalism in terms of computational descriptions of varying strength—computational interpretations of physical microstates and dynamics that vary in their restrictiveness. We distinguish several types of pancomputationalism and identify essential features of the computational descriptions required to support them. By tying various pancomputationalist theses directly to notions of what counts as (...) computation in a physical system, we clarify the meaning, strength, and plausibility of pancomputationalist claims. We show that the force of these claims is diminished when weaknesses in their supporting computational descriptions are laid bare. Specifically, once computation is meaningfully distinguished from ordinary dynamics, the most sensational pancomputationalist claims are unwarranted, whereas the more modest claims offer little more than recognition of causal similarities between physical processes and the most primitive computing processes.

What is a computer? What distinguishes computers from other artificial or natural systems with alleged computational capacities? What does use of a physical system for computation entail, and what distinguishes such use from otherwise identical transformation of that same system when it is not so used? This paper addresses such questions through a theory of information processing artifacts, the class of technical artifacts with physical capacities that enable agents to use them as means to their computational ends. Function ascription, use (...) plan requirements, malfunction, and efficacy of IPAs are all addressed in this theory, with emphasis on artifacts that can be used—reliably or otherwise—for digital computation. By explicitly distinguishing physically grounded computational capacities from user-ascribed computational functions, and by recognizing the distinct roles of each for the implementation of computations in artifacts, this theory clearly distinguishes the use of physical systems for computation from the transformations of physical system states that enable such use. As such, it provides a rigorous basis for distinguishing “computers” from other artificial and natural systems—a distinction whose nature and legitimacy faces ever-evolving challenges from multiple disciplines. This theory, and the associated “instrumental” view of computation in artifacts, naturally accommodates the openminded but scrupulous consideration of radically unconventional physical systems as potential substrates for future computers.

This study investigated the relationship between concussions and medication adherence among 247 adults experiencing homelessness in Oklahoma City, Oklahoma, who were prescribed medication for a psychiatric disorder. Participants were asked whether they had “ever experienced a blow to the head that caused a concussion,” and medication adherence was measured by asking participants whether they had taken their psychiatric medication yesterday. The data were analyzed using univariate and multivariable logistic regressions. Results showed that more than half of the sample had a (...) concussion history, and homeless adults with a concussion history had higher odds of non-adherence to psychiatric medications compared with those who reported no concussion history [OR = 2.13 ]. Findings suggest that medication non-adherence is associated with incurred concussions. Raising awareness among service providers of the relationship between traumatic brain injury and medication adherence may increase efforts to improve adherence in this underserved population.

The aim of this study was to analyze the association between physical activity and eating habits during the COVID-19 pandemic among Brazilian adults. A sample of 1,929 participants answered an online survey, however 1,874 were included in the analysis. The impact of the COVID-19 pandemic on eating habits was assessed inquiring about participants' intake of fruits, vegetables, fried foods, and sweets during the pandemic. Physical activity was assessed by asking participants about their weekly frequency, intensity and number of minutes/hours engaging (...) in structured physical activities per week. Participants were then stratified into categories based on moderate-to-vigorous intensity and into active or inactive. Increased sweets consumption was the most commonly reported change to eating habits, followed by an increase in the consumption of vegetables, fruits, and fried foods. Physical activity practice was related to lower consumption of fried foods and sweets. A cluster analysis revealed subjects with higher the level of physical activity was more likely to follow a healthy diet. Thus, physical activity was positively associated with healthier eating habits. Health authorities must recommend regular physical as a strategy to improve overall health during the COVID-19 pandemic. Future studies should address the physical activity interventions to improve health status during a pandemic. (shrink)

Aggleton & Brown argue that a hippocampal-anterior thalamic system supports the “recollection” of contextual information about previous events, and that a separate perirhinal-medial dorsal thalamic system supports detection of stimulus “familiarity.” Although there is a growing body of human literature that is in agreement with these claims, when recollection and familiarity have been examined in amnesics using the process dissociation or the remember/know procedures, the results do not seem to provide consistent support. We reexamine these studies and describe the results (...) of an additional experiment using a receiver operating characteristic (ROC) technique. The results of the reanalysis and the ROC experiment are consistent with Aggleton & Brown's proposal. Patients with damage to both regions exhibit severe deficits in recollection and smaller, but consistent, deficits in familiarity. (shrink)

Although informed consent is important in clinical research, questions persist regarding when it is necessary, what it requires, and how it should be obtained. The standard view in research ethics is that the function of informed consent is to respect individual autonomy. However, consent processes are multidimensional and serve other ethical functions as well. These functions deserve particular attention when barriers to consent exist. We argue that consent serves seven ethically important and conceptually distinct functions. The first four functions pertain (...) principally to individual participants: (1) providing transparency; (2) allowing control and authorization; (3) promoting concordance with participants' values; and (4) protecting and promoting welfare interests. Three other functions are systemic or policy focused: (5) promoting trust; (6) satisfying regulatory requirements; and (7) promoting integrity in research. Reframing consent around these functions can guide approaches to consent that are context sensitive and that maximize achievable goals. (shrink)

Despite the importance of extrapair copulation (EPC) in human evolution, almost nothing is known about the design features of EPC detection mechanisms. We tested for sex differences in EPC inference-making mechanisms in a sample of 203 young couples. Men made more accurate inferences (φmen = 0.66, φwomen = 0.46), and the ratio of positive errors to negative errors was higher for men than for women (1.22 vs. 0.18). Since some may have been reluctant to admit EPC behavior, we modeled how (...) underreporting could have influenced these results. These analyses indicated that it would take highly sex-differentiated levels of underreporting by subjects with trusting partners for there to be no real sex difference. Further analyses indicated that men may be less willing to harbor unresolved suspicions about their partners’ EPC behavior, which may explain the sex difference in accuracy. Finally, we estimated that women underreported their own EPC behavior (10%) more than men (0%). (shrink)

Researchers from diverse disciplines, including organismal and cellular physiology, sports science, human nutrition, evolution and ecology, have sought to understand the causes and consequences of the surprising variation in metabolic rate found among and within individual animals of the same species. Research in this area has been hampered by differences in approach, terminology and methodology, and the context in which measurements are made. Recent advances provide important opportunities to identify and address the key questions in the field. By bringing together (...) researchers from different areas of biology and biomedicine, we describe and evaluate these developments and the insights they could yield, highlighting the need for more standardisation across disciplines. We conclude with a list of important questions that can now be addressed by developing a common conceptual and methodological toolkit for studies on metabolic variation in animals. (shrink)

This is the first chapter to our edited collection of essays on the nature and ethics of blame. In this chapter we introduce the reader to contemporary discussions about blame and its relationship to other issues (e.g. free will and moral responsibility), and we situate the essays in this volume with respect to those discussions.

The manifest appearance of function and purpose in living systems is responsible for the prevalence of apparently teleological explanations of organismic structure and behavior in biology. Although the attribution of function and purpose to living systems is an ancient practice, teleological notions are largely considered ineliminable from modern biological sciences, such as evolutionary biology, genetics, medicine, ethology, and psychiatry, because they play an important explanatory role. Historical and recent examples of teleological claims include the following: The chief function of the (...) heart is the transmission and pumping of the blood through the arteries to the extremities of the body. (Harvey 1616 [1928: 49]) The Predator Detection hypothesis remains the strongest candidate for the function of stotting [by gazelles]. (Caro 1986: 663) The geographic range of human malaria is much wider than the range of the sickle-cell gene. As it happens, other antimalarial genes take over the protective function of the sickle-cell gene in … other warm parts. (Diamond 1994: 83) Despite the substantial amount of data we now have on theropod dinosaurs, more information is necessary in order to determine the likelihood that early feathers served an adaptive function in visual display as opposed to other proposed adaptive functions such as thermoregulation. (Dimond et al. 2011: 62) The ubiquity of claims such as these raises the question: how should apparently teleological notions in biology be understood? Most post-Darwinian approaches attempt to naturalize teleology in biology, in opposition to nineteenth-century viewpoints which grounded it theologically. Nevertheless, biologists and philosophers have continued to question the legitimacy of teleological notions in biology. For instance, Ernst Mayr (1988), identified four reasons why teleological notions remain controversial in biology, namely that they are: vitalistic (positing some special ‘life-force’); requiring backwards causation (because goal-directed explanations seem to use future outcomes to explain present traits); incompatible with mechanistic explanation (because of 1 and 2); mentalistic (attributing the action of mind where there is none). A fifth complaint is that they are not empirically testable (Allen & Bekoff 1995). The current philosophical literature offers both Darwinian and non-Darwinian accounts of teleology in biology that aim to avoid these concerns. In this article, we hope to bring some clarity to the contemporary debates over the role of teleological notions in biology by sketching a taxonomy of the various accounts of biological function on offer (see Allen & Bekoff 1995 for a more comprehensive taxonomy that forms the basis of this presentation). We primarily focus on naturalistic accounts of biological function, since this is where we see the most lively and productive current debates (see, e.g., Garson 2016 for an extended survey). We also briefly discuss the notion of goal-directedness in section 2. (shrink)

Accelerating Turing machines have attracted much attention in the last decade or so. They have been described as “the work-horse of hypercomputation” (Potgieter and Rosinger 2010: 853). But do they really compute beyond the “Turing limit”—e.g., compute the halting function? We argue that the answer depends on what you mean by an accelerating Turing machine, on what you mean by computation, and even on what you mean by a Turing machine. We show first that in the current literature the term (...) “accelerating Turing machine” is used to refer to two very different species of accelerating machine, which we call end-stage-in and end-stage-out machines, respectively. We argue that end-stage-in accelerating machines are not Turing machines at all. We then present two differing conceptions of computation, the internal and the external, and introduce the notion of an epistemic embedding of a computation. We argue that no accelerating Turing machine computes the halting function in the internal sense. Finally, we distinguish between two very different conceptions of the Turing machine, the purist conception and the realist conception; and we argue that Turing himself was no subscriber to the purist conception. We conclude that under the realist conception, but not under the purist conception, an accelerating Turing machine is able to compute the halting function in the external sense. We adopt a relatively informal approach throughout, since we take the key issues to be philosophical rather than mathematical. (shrink)

The aim of this study was to examine the predictions of three theories of human logical reasoning, (a) mental model theory, (b) formal rules theory (e.g., PSYCOP), and (c) the probability heuristics model, regarding the inferences people make for extended categorical syllogisms. Most research with extended syllogisms has been restricted to the quantifier “All” and to an asymmetrical presentation. This study used three-premise syllogisms with the additional quantifiers that are used for traditional categorical syllogisms as well as additional syllogistic figures. (...) The predictions of the theories were examined using overall accuracy as well as a multinomial tree modelling technique. The results demonstrated that all three theories were able to predict response selections at high levels. However, the modelling analyses showed that the probability heuristics model did the best in both Experiments 1 and 2. (shrink)

The "Ignorance Interpretation" of quantum mechanical mixtures holds, roughly, that whenever a system S belongs to an ensemble, which is represented by a mixed statistical operator U=Σ pi P[ψ i] (0≤ pi≤ 1, Σ ipi=1,P[ψ i] is the projection operator for the state ψ i), then S is in some pure state, although we are ignorant as to which one. It has been concluded, e.g. by van Fraassen, that "the ignorance interpretation is untenable," and he presumably favors adopting "the position (...) that mixtures of pure states are themselves new states...to say that a system is in a proper mixture is to say that it is not in a pure state." I wish to argue in this paper that there are no good grounds for rejecting the ignorance interpretation. (shrink)

A “slingshot” proof suggested by Kurt Gödel (1944) has been recast by Stephen Neale (1995) as a deductive argument showing that no non-truthfunctional sentence connective can permit the combined use, within its scope, of two truth-functionally valid inference principles involving defi- nite descriptions. According to Neale, this result provides indirect support for Russell’s Theory of Descriptions and has broader philosophical repercussions because descriptions occur in non-truth-functional constructions used to motivate talk about (e.g.) necessity, time, probability, causation, obligation, facts, states of (...) affairs, and propositions.

This paper is a critical examination of Stephen Neale's *The Philosophical Significance of Godel's slingshot*. I am sceptical of the philosophical significance of Godel’s Slingshot (and of Slingshot arguments in general). In particular, I do not believe that Godel’s Slingshot has any interesting and important philosophical consequences for theories of facts or for referential treatments of definite descriptions. More generally, I do not believe that any Slingshot arguments have interesting and important philosophical consequences for theories of facts or for referential (...) treatments of definite descriptions. Friends of facts and referential treatments of definite descriptions can, and should, proceed with the construction of their theories, blithely ignoring the many Slingshots which now litter the landscape. (Of course, there may be other considerations which should give such theorists pause -- but those are other considerations.). (shrink)

The aim of this paper is to provide a preliminary defence of the use of the concept of dignity in legal and ethical discourse. This will involve the application of three philosophical insights: (1) Ludwig Wittgenstein’s notion of language-games; (2) his related approach to understanding the meanings of words (sometimes summarised as ‘meaning is use’); and (3) Jeremy Waldron’s layered understanding of property wherein ‘property’ consists in an abstract concept fleshed out in numerous particular conceptions. These three insights will be (...) applied, in the first place, to the concept of ‘dignity’, which is chosen here as a good example of a concept which is both vague and contested in legal and ethical discourse, but which can nevertheless be rendered workable by the application of the aforementioned insights. Later, the analysis will be extended briefly to some other troublesome concepts in order to demonstrate its general application. This paper is concerned primarily with formal, rather than substantive questions about dignity. Matters of content will be touched on only insofar as is necessary to illustrate and illuminate my argument about how we ought to approach (rather than answer) questions about dignity. It should be emphasised that because there is no intention of exploring substantive questions in any depth, the discussion here will not delve into the criticisms of ‘speciesism’ often levelled against the idea of ‘human dignity’. ‘Speciesist’ theories are those that claim that the status, value, or rights of human beings can be regarded as being higher than that of other animals, purely on the basis of their membership of the human species, and without justifying the distinction by pointing to any relevant capacity or characteristic possessed by all and only human beings. For a critical description of speciesism see, e.g., Singer [18] Chapter Three passim; for present purposes, the term ‘dignity’ will be used synonymously with ‘human dignity’, and concerns about speciesism will not be considered.

Traditional accounts hold that reference consists in a relation between the mind and an object; the relation is effected by a mental act and mediated by internal mental contents (internal representations). Contemporary theories as diverse as Fodor’s [Fodor, J.A., 1987. Psychosemantics: The Problem of Meaning in the Philosophy of Mind. MIT Press, Cambridge, MA] language of thought hypothesis, Dretske’s [Dretske, F., 1988. Explaining Behaviour: Reasons in a World of Causes. MIT Press, Cambridge, MA] informational semantics and Millikan’s [Millikan, R.G., 1984. (...) Language, Thought and Other Biological Categories: New Foundations for Realism. MIT Press, Cambridge, MA] teleosemantics share this act– content–object picture (which was also held by several early modern philosophers, in particular Locke). The core of the traditional view is the thesis that reference and intentionality are relational (‘thesis RR’). Although deeply problematic, RR is entrenched also in psychology, linguistics, cognitive science and Artificial Intelligence. Using for the most part arguments employed by Wittgenstein, we mount a case against RR and advance a deflationary account of reference and intentionality according to which neither is relational.

Our focus in this chapter will be the role the pride has played, both historically and contemporarily, in Christian theology and philosophical theology. We begin by delineating a number of different types of pride, since some types are positive (e.g., when a parent tells a daughter “I’m proud of you for being brave”), and others are negative (e.g., “Pride goes before a fall”) or even vicious. We then explore the role that the negative emotion and vice play in the history (...) of Christianity, with particular attention to a number of influential figures. We conclude by exploring how pride connects with a number of other central issues in Christian theology. (shrink)

In 1959, Neal Miller made the bold claim that the Stimulus–Response, Behaviorist models of that era were describing the way in which stimuli lead to the entry of contents into consciousness. Today, researchers have begun to investigate the link between external stimuli and involuntary entry, using paradigms such as the reflexive imagery task, the focus of our review. The RIT has revealed that stimuli can elicit insuppressible entry of high-level cognitions. Knowledge of the boundary conditions of the RIT effect (...) illuminates the limitations of involuntary processes and the role of consciousness in the regulation of behavior. We review the boundary conditions of this paradigm as well as its systematic effects. Systematic effects are unlikely to be due to experimental demand. While reviewing each effect, we consider its theoretical implications. In addition, throughout our review, we discuss future directions for the study of insuppressible entry using the RIT. Last, we discuss a theoretical development that stems from the RIT and illuminates how involuntary entry and encapsulation, though at times disadvantageous for the actor, are essential for adaptive action selection during the course of ontogeny.

This article involves a close reading of two African American authors, Zora Neale Hurston, an acclaimed novelist and Katie Cannon, an influential theological ethicist. Texts from Steve Biko on black consciousness and from James Cone on liberation theology are used as methodological tools in trying to ascertain the degree to which Hurston and Cannon espouse a black consciousness. A strong resonance of black consciousness will indeed be found in Hurston’s and Cannon’s texts. The conclusion drawn is that not only is (...) there a resonance of black consciousness, but both writers also give proof of a black womanist consciousness that reveals new knowledge. Cannon’s oeuvre also begs the question of epistemological privilege. In addition, an animated critique is registered between these women scholars and male colleagues, in the world of fiction and academia.Contribution: This article demonstrates a link from South African black consciousness to black womanist thinkers in the United States. A connection is also made between male, black liberation theology and black womanist thinking, while expounding the womanist approach, liberated from male dominance, on par with all others. (shrink)

In this chapter I articulate the threat that time travel to the past allegedly poses to the free will of the time traveler, and I argue that on the traditional way of thinking about free will, the incompatibilist about time travel and free will wins the day. However, a residual worry about the incompatibilist view points the way toward a novel way of thinking about free will, one that I tentatively explore toward the end of the chapter.

In this paper I argue that adopting a perdurance view of persistence through time does not lead to skepticism about moral responsibility, despite what many theorists have thought.

This chapter explores the concept of judgmentalism: what it is and why it’s morally problematic. After criticizing an account offered by Gary Watson, the paper argues for a broader understanding of what it is to be judgmental, encompassing not just the overall beliefs that we form about someone else, but also the very pattern of our thoughts about those with whom we are involved in interpersonal relationships. The thesis is that to care about someone is to be oriented toward them, (...) or to see them through a particular mental lens, in a way that produces a particular pattern of salience and silence. That is: caring about someone (at least ideally) has the effect of making some features of that person particularly salient, and silencing or screening off other features from one’s consciousness. One is aptly described as judgmental when one’s thoughts do not display this sort of pattern, indicating a failure to fully adopt the orientation that constitutes properly caring about the person.

Names, descriptions, and demonstratives raise well-known logical, ontological, and epistemological problems. Perhaps less well known, amongst philosophers at least, are the ways in which some of these problems not only recur with pronouns but also cross-cut further problems exposed by the study in generative linguistics of morpho-syntactic constraints on interpretation. These problems will be my primary concern here, but I want to address them within a general picture of interpretation that is required if wires are not to be crossed. That (...) picture will be sketched in sections 3 and 4; subsequent sections will focus on pronouns and binding, drawing heavily on what has preceded. (shrink)

In this study, we test the interactive effect on ethical decision-making of (1) personal characteristics, and (2) personal expectanciesbased on perceptions of organizational rewards and punishments. Personal characteristics studied were cognitive moral developmentand belief in a just world.

Further, outcome expectancies and belief in a just world interacted with managers’ cognitive moral development to influence managers’ ethical decision-making. In particular, low-cognitive moral development managers who (...) expected that their organization condoned unethical behavior made less ethical decisions while high cognitive moral development managers became more ethical in this environment. Low cognitive moral development managers also behaved less ethically when their belief in a just world was high. (shrink)

Do the dynamics of a physical system determine what function the system computes? Except in special cases, the answer is no: it is often indeterminate what function a given physical system computes. Accordingly, care should be taken when the question ‘What does a particular neuronal system do?’ is answered by hypothesising that the system computes a particular function. The phenomenon of the indeterminacy of computation has important implications for the development of computational explanations of biological systems. Additionally, the phenomenon lends (...) some support to the idea that a single neuronal structure may perform multiple cognitive functions, each subserved by a different computation. We provide an overarching conceptual framework in order to further the philosophical debate on the nature of computational indeterminacy and computational explanation. (shrink)

Alan Turing, pioneer of computing and WWII codebreaker, is one of the most important and influential thinkers of the twentieth century. In this volume for the first time his key writings are made available to a broad, non-specialist readership. They make fascinating reading both in their own right and for their historic significance: contemporary computational theory, cognitive science, artificial intelligence, and artificial life all spring from this ground-breaking work, which is also rich in philosophical and logical insight.

Despite a long period of neglect, research on emotion in organizational behavior has developed into a major field over the past 15 years, and is now seen to be part of an affective revolution in the organization sciences. In this article, we review current research on emotion in the organizational behavior field based on five levels of analysis: within person, between persons, dyadic interactions, leadership and teams, and organization-wide. Specific topics we cover include affective events theory, state and trait affect (...) and mood, emotional intelligence, emotional labor, emotional contagion, emotions and leadership, and building a healthy emotional climate. We conclude with suggestions for future research. (shrink)

This paper reports the results of a survey of ethical attitudes, values, and propensities in public sector employees in Australia. It was expected that demographic variables, personal values, and contextual variables at the individual level, and group- and organisational-level values would predict use of formal codes of ethics and ethical tolerance (tolerance of unethical behaviour). Useable data were received from 500 respondents selected at random across public sector organisations in a single Australian state. Results supported the study hypotheses, but indicated (...) that different mechanisms underlie each of the criterion variables. Use of ethical codes was determined primarily on the basis of a perception that others use the code, while ethical tolerance was determined by personal values. At an applied level, the research highlights the need for orgasnizations to establish a critical mass of code users, so that this operates as a normative influence on others in the organization.

An increasingly popular solution to the anti-scientific climate rising on social media platforms has been the appeal to more critical thinking from the user's side. In this paper, we zoom in on the ideal of critical thinking and unpack it in order to see, specifically, whether it can provide enough epistemic agency so that users endowed with it can break free from enclosed communities on social media (so called epistemic bubbles). We criticise some assumptions embedded in the ideal of critical (...) thinking online and, instead, we propose that a better way to understand the virtuous behaviour at hand is as critical engagement, namely a mutual cultivation of critical skills among the members of an epistemic bubble. This mutual cultivation allows members within an epistemic bubble (in contrast, as we will show, with the authority-based models of epistemic echo chambers) to become more autonomous critical thinkers by cultivating self-trust. We use the model of relational autonomy as well as resources from work on epistemic self-trust and epistemic interdependence to develop an explanatory framework, which in turn may ground rules for identifying and creating virtuous epistemic bubbles within the environments of social media platforms.
