Acute aerobic exercise has been shown to improve fine motor skills and alter activation of the motor cortex. The intensity of exercise may influence M1 activation, and further impact whole-body motor skill performance. The aims of the current study were to compare a whole-body motor skill via a piano task following moderate-intensity training and high-intensity interval training, and to determine if M1 activation is linked to any such changes in performance. Nine subjects, aged 18 ± 1 years completed a control, (...) MIT, and HIIT trial followed by administration of a piano performance task. M1 activation was evaluated by measuring oxyhemoglobin and hemoglobin difference changes during post-exercise piano performance using functional near-infrared spectroscopy. The results indicate that piano performance scores were higher after the MIT trial, but not HIIT trial, compared to the control trial. A negative relationship was detected between heart rate during HIIT and post-HIIT piano scores. M1 activation was significantly increased after the HIIT trial. M1 activation was also positively associated with piano performance when exercise trials and all trials were combined. We found that acute moderate-intensity exercise led to an improvement in complex motor skill performance while higher-intensity exercise increased M1 activation. These results demonstrate that moderate-intensity exercise can prime the nervous system for the acquisition of whole-body motor skills, suggesting that similar exercise protocols may be effective in improving the outcomes of other motor tasks performed during regular routines of daily life. In addition, it appears that improvements in motor task performance may be driven by M1 activation. Our findings provide new mechanistic insight into the complex relationship between exercise intensity, M1 activation, and whole-body motor skill performance. (shrink)

Catholic theology’s traditional understanding of the spiritual nature of the human person begins with the idea of a rational soul and human mind that is made manifest in free will—the spiritual experience of the act of consciousness and cause of all human arts. The rationale for this religion-based idea of personhood is key to understanding ethical dilemmas posed by modern research that applies a more empirical methodology in its interpretations about the cause of human consciousness. Applications of these beliefs about (...) the body/soul composite to the theory of evolution and to discoveries in neuroscience, paleoanthropology, as well as to recent animal intelligence studies, can be interpreted from this religious and philosophical perspective, which argues for the human soul as the unifying cause of the person’s unique abilities. Free will and consciousness are at the nexus of the mutual influence of body and soul upon one another in the traditional Catholic view, that argues for a spiritual dimension to personality that is on a par with the physical metabolic processes at play. Therapies that affect consciousness are ethically problematic, because of their implications for free will and human dignity. Studies of resilience, as an example, argue for the greater, albeit limited, role of the soul’s conscious choices in healing as opposed to metabolic or physical changes to the brain alone. (shrink)

Ancient DNA has been discovered in many types of preserved biological material, including bones, mummies, museum skins, insects in amber and plant fossils, and has become an important research tool in disciplines as diverse as archaeology, conservation biology and forensic science. In archaeology, ancient DNA can contribute both to the interpretation of individual sites and to the development of hypotheses about past populations. Site interpretation is aided by DNA‐based sex typing of fragmentary human bones, and by the use of genetic (...) techniques to assess the degree of kinship between the remains of different individuals. On a broader scale, population migrations can be traced by studying genetic markers in ancient DNA, as in recent studies of the colonisation of the Pacific islands, while ancient DNA in preserved plant remains can provide information on the development of agriculture.

Duchenne's muscular dystrophy (DMD), which affects 1/3500 live male births, involves a progressive degeneration of skeletal and cardiac muscle, leading to early death. The protein dystrophin is lacking in DMD and present, but defective, in the allelic, less severe, Becker muscular dystrophy and is also missing in the mdx mouse. Experiments on the mdx mouse have suggested two possible therapies for these myopathies. Implantation of normal muscle precursor cells (mpc) into mdx skeletal muscle leads to the conversion of dystrophin‐negative fibres (...) to ‐positive, with consequent improvement in muscle histology. Direct injectidn of dystrophin cDNA into skeletal or cardiac muscle also gives rise to dystrophin‐positive fibres. Although both appear promising, there are a number of questions to be answered and refinements to be made before either technique could be considered possible as treatments for myopathies in man.

Significant life events tend to cause transformational change, but most narratives in agriculture focus on how negative life events such as death, bankruptcy, and health problems have created change. International experiences can be positive, significant life events. Transformational tourism has been shown to change travelers’ behavior. Therefore, we propose to examine the perceived outcomes of international experiences by agricultural leadership alums. Unstructured interviews with 36 agricultural leadership alums from IFYE, Nuffield, and LEAD Nebraska with distinctive international experiences were interviewed. The (...) international experiences varied in purpose, time abroad, cultural immersion, structured travel, and independent study. This study answers the following questions: (1) How does international travel for producers lead to transformation? (2) How does international travel support behavior change? Data show the international experiences were impactful and transformative due to two processes that occurred during the international experience. First, agricultural leadership participants experienced disorienting events that forced them to reconsider and reject their current mental models of the agricultural system. Second, experiential learning through visiting farms, meeting producers, and spending time reflecting on what they were experiencing with their peers allowed the participants to rebuild their mental models and be inclusive of the broader agricultural system. During these two processes, the participants’ attitudes, subjective norms, and perceived behavior control of new agricultural practices, sustainable agriculture, and possible options within the agricultural system expanded. Short-term international experiences were an important gateway to further international experiences. Longer-term international experiences that involved independent study, cultural immersion, and global network development supported the adoption of sustainable agriculture through perceived attitudes, social norms, and behavioral control. To support transformational change in the agricultural system, we need as many tools as possible to support practitioners. International experiences provide a tool to support transformational change.

Based on theoretical considerations of Aurell (1979) and Block (1995), we argue that object recognition awareness is distinct from purely sensory awareness and that the former is mediated by neuronal activities in areas that are separate and distinct from cortical sensory areas. We propose that two of the principal functions of neuronal activities in sensory cortex, which are to provide sensory awareness and to effect the computations that are necessary for object recognition, are dissociated. We provide examples of how this (...) dissociation might be achieved and argue that the components of the neuronal activities which carry the computations do not directly enter the awareness of the subject. The results of these computations are sparse representations (i.e., vector or distributed codes) which are activated by the presentation of particular sensory objects and are essentially engrams for the recognition of objects. These final representations occur in the highest order areas of sensory cortex; in the visual analyzer, the areas include the anterior part of the inferior temporal cortex and the perirhinal cortex. We propose, based on lesion and connectional data, that the two areas in which activities provide recognition awareness are the temporopolar cortex and the medial orbitofrontal cortex. Activities in the temporopolar cortex provide the recognition awareness of objects learned in the remote past (consolidated object recognition), and those in the medial orbitofrontal cortex provide the recognition awareness of objects learned in the recent past. The activation of the sparse representation for a particular sensory object in turn activates neurons in one or both of these regions of cortex, and it is the activities of these neurons that provide the awareness of recognition of the object in question. The neural circuitry involved in the activation of these representations is discussed. (shrink)

ABSTRACT:In this address, I distinguish and explore three conceptions of wages. A wage is a reward, given in recognition of the performance of a valued task. It is also an incentive: a way to entice workers to take and keep jobs, and to motivate them to work hard. Finally, a wage is a price of labor, and like all prices, conveys valuable information about relative scarcity. I show that each conception of wages has its own normative logic, or appropriate justification, (...) and these logics can come apart. This explains some of the debate about wages and makes the project of justifying a wagesimpliciterdifficult. I identify which logic we should choose, since we must choose, and say what this means for how we should think about the justification of pay. (shrink)

Some writers think that John Rawls rejects desert as a distributive criterion because he thinks that people are not capable of deserving anything. I argue that Rawls does not think this, and that he rejects desert because he thinks that we cannot tell what people deserve. I then offer a criticism of Rawls's rejection of desert based on its correct interpretation.

It has been shown that visual awareness in the blind hemifield of hemianopic cats that have undergone unilateral ablations of visual cortex can be restored by sectioning the commissure of the superior colliculus or by destroying a portion of the substantia nigra contralateral to the cortical lesion (the Sprague effect). We propose that the visual awareness that is recovered is due to synchronized oscillatory activities in the superior colliculus ipsilateral to the cortical lesion. These oscillatory activities are normally partially suppressed (...) by the inhibitory, GABAergic contralateral nigrotectal projection, and the destruction of the substantia nigra, or the sectioning of the collicular commissure, disinhibits the collicular neurons, causing an increase in the extent of oscillatory activity and/or synchronization between activities at different sites. This increase in the oscillatory and synchronized character is sufficient for the activities to give rise to visual awareness. We argue that in rodents and lower vertebrates, normal visual awareness is partly due to synchronized oscillatory activities in the optic tectum and partly due to similar activities in visual cortex. It is only in carnivores and primates that visual awareness is wholly due to cortical activities. Based on von Baerian recapitulation theory, we propose that, even in humans, there is a period in early infancy when visual awareness is partially due to activities in the superior colliculus, but that this awareness gradually disappears as the nigrotectal projection matures.

The view of business ethics that Christopher McMahon calls the “implicit morality of the market” and Joseph Heath calls the “market failures approach” has received a significant amount of recent attention. The idea of this view is that we can derive an ethics for market participants by thinking about the “point” of market activity, and asking what the world would have to be like for this point to be realized. While this view has been much-discussed, it is still not well-understood. (...) This paper seeks to remedy this problem. I begin by showing, against some recent commentators, that McMahon’s view and Heath’s view are fundamentally the same. Second, I clarify the sense of “efficiency” at work in the market failures approach. Finally, I argue that, in its current form, this view has little relevance to the real world of business. I conclude by sketching two ways of modifying it to fit our world. (shrink)

This book is a study of Blaise Pascal's defence of Christian belief in the Pensees. Michael Moriarty aims to expound--and in places to criticize--what he argues is a coherent and original apologetic strategy. Setting out the basic philosophical and theological presuppositions of Pascal's project, the present volume draws the distinction between convictions attained by reason and those inspired by God-given faith. It also presents Pascal's view of the contradictions within human nature, between the 'wretchedness' and the 'greatness'. His mind-body (...) dualism and his mechanistic conception of non-human animals are discussed. Pascal invokes the biblical story of the Fall and the doctrine of original sin as the only credible explanation of these contradictions. His analysis of human occupations as powered by the twin desire to escape from painful thoughts and to gratify one's vanity is subjected to critical examination, as is his conception of the self and self-love. Pascal argues that just as Christianity propounds the only explanation for the human condition, so it offers the only kind of happiness that would satisfy our deepest longings. He thus reasons that we have an interest in investigating its truth-claims as rooted in the Bible and in history. The closing chapters of this book discuss Pascal's view of Christian morality and the famous 'wager' argument for opting in favour of Christian belief. (shrink)

The focus of this article is to highlight some of the inherent gender injustices experienced by the female pastors within the Apostolic Faith Mission in Zimbabwe. Drawing insights from the field research conducted in pursuance of a doctoral programme, the study foregrounds some of the barriers that women have had to endure when it comes to the issue of being ordained as a pastor. The article also interrogates the reasons used as a basis to exclude female pastors from the key (...) decision-making bodies and to deny them the opportunity to preach at the national conference, which is the biggest gathering within the AFMZ. This is a qualitative study utilising interviews, focus group discussions and the observation method. The main findings emerging from this study reveal that whilst some positive changes have been made towards the inclusion of women in the pastoral ministry, however, there are still many gaps needing urgent attention before the AFMZ becomes a gender-inclusive and gender-equitable faith community.Contribution: This article foregrounds the challenges faced by female pastors in the AFMZ. It advocates for gender mainstreaming and gender inclusive policies in the AFMZ leadership structures. This is in sync with the focus of this collection, for which the main thrust is on women and religious leadership. (shrink)

Recent experiments have shown that the amplitudes of cortical gamma band oscillatory activities that occur during anesthesia are often greater than amplitudes of similar activities that occur without anesthesia. This result is apparently at odds with the hypothesis that synchronized oscillatory activities constitute the neural correlate of consciousness. We argue that while synchronization and oscillatory patterning are necessary conditions for consciousness, they are not sufficient. Based on the results of a binocular rivalry study of Fries et al. (1997), we propose (...) that the degrees of oscillatory strength and synchronization of neuronal activities determine the degree of awareness those activities produce. On the other hand, the overal firing rates of neurons in cortical sensory areas are not correlated with the degree of awareness the activities of those neurons produce. The results of the experiment of Fries et al. (1997) appear to conflict with the results of another binocular rivalry experiment, in which monkeys were trained to pull a lever in order to report which stimulus object was being perceived (Leopold & Logothetis, 1996). In the latter experiment, it was demonstrated that the firing rates of neurons in striate cortex did not change during perceptual alterations, while 90% of neurons in inferior and superior temporal cortices changed their firing rate when the perceived image changed. This result led to the conclusion that activities in temporal cortex are correlated with visual awareness, but those in striate cortex are not. We argue that activities in temporal cortex contribute little, if anything, to perceptual awareness, and that their primary function is computational. Thus the correlation between the firing rates of neurons in these areas and the responses of the monkeys is due to the recognition of a particular stimulus object, which in turn is due to the computations made there.

The neural and endocrine bases of the generation of thirst are reviewed. Based on this review, a hierarchical system of neural structures that regulate water conservation and acquisition is proposed. The system includes primary sensory-receptive areas; secondary sensory structures (circumventricular organs), which detect levels of hormones, including angiotensin II and vasopressin, which are involved in generating thirst; preoptic and hypothalamic structures; and an area within the ventrolateral quadrant of the periaqueductal gray matter. Hodological and other data are used to determine (...) the hierarchical organization of the system. Based on studies of the effects of lesions to various structures within the hierarchy of the system, it is proposed that the awareness of thirst in rodents is either entirely or predominantly due to neuronal activities in a subsection of the ventrolateral periaqueductal gray matter. It is also hypothesized that the awareness of thirst in primates is due to neuronal activities in both the ventrolateral periaqueductal gray and in a region within the medial prefrontal and anterior cingulate cortex.

John Rawls says that one of the requirements for stability is “[s]ociety as an employer of last resort” (PLP, lix). He explains: “[t]he lack of . . . the opportunity for meaningful work and occupation is destructive . . . of citizens’ self-respect” (PLP, lix). Rawls implies in these claims that the opportunity for meaningful work is a social basis of self-respect. This constitutes a significant shift in his account of self-respect, one that has been overlooked. I begin by clarifying (...) Rawls’s account of self-respect in A Theory of Justice, then consider some post-Theory developments in it. After exploring the nature of Rawls’s commitment to the opportunity for meaningful work, I ask why he comes to think it is a social basis of self-respect. I extract a partial answer from his writings, then speculate about his full reasoning. Finally, I consider whether Rawls is right that the opportunity for meaningful work is a social basis of self-respect. I give some reason to believe that he is. (shrink)

Packed with examples, this book offers a clear and engaging overview of ethical issues in business. -/- It begins with a discussion of foundational issues, including the objectivity of ethics, the content of ethical theories, and the debate between capitalism and socialism, making it suitable for the beginning student. It then examines ethical issues in business in three broad areas. The first is the market. Issues explored are what can be sold (the limits of markets) and how it can be (...) sold (ethics in marketing). The second is work. Topics in this area are health and safety, meaningful work, compensation, hiring and firing, privacy, and whistleblowing. The third area is the firm in society. Here readers explore corporate social responsibility, corporate political activity, and the set of ethical challenges that attend international business. -/- Issues are introduced through real-world examples that underscore their importance and make them come alive. Arguments for opposing positions are given fair hearings and students are encouraged to develop and defend their own views. (shrink)

Should people who perform equal work receive equal pay? Most would say ‘yes’, at least insofar as this question is understood to be asking whether employers should be permitted to discriminate against employees on the basis of race or sex. But suppose the employees belong to all of the same traditionally protected groups. Is (what I call) nondiscriminatory unequal pay for equal work wrong? Drawing an analogy with price discrimination, I argue that it is not intrinsically wrong, but it can (...) be deceptive, in which case it is wrong. (shrink)

Online retailers are using advances in data collection and computing technologies to “personalize” prices, i.e., offer goods for sale to shoppers at their reservation prices, or the highest price they are willing to pay. In this paper, I offer a criticism of this practice. I begin by putting online personalized pricing in context. It is not something entirely new, but rather a kind of price discrimination, a familiar pricing practice. I then offer a fairness-based argument against it. When an online (...) retailer personalizes prices, it competes unfairly for the social surplus created by a transaction. I defend this argument against objections, and offer a simple remedy: online retailers should either disclose that they are personalizing prices, or stop doing so. (shrink)

Justice requires giving people what they deserve. Or so many philosophers – and according to many of those philosophers, everyone else – thought for centuries. In the 1970’s and 1980’s, however, perhaps under the influence of Rawls’s (1971) desert-less theory, desert was largely cast out of discussions of distributive justice. Now it is making a comeback. In this chapter I consider recent research on the concept of desert, arguments for its requital, and connections between desert and other distributive ideals. I (...) suggest that desert-sensitive theories of distributive justice, though they face obstacles, have a promising future. (shrink)

Philosophical naturalists deny the existence of anything supernatural, such as God, souls, demons, ghosts, angels, witchcraft, miracles, etc. They believe that human beings are animals whose existence is entirely governed by the same laws which govern the rest of the natural world. However, some environmentalists value nature intrinsically and aesthetically, and in doing so conceive of nature as that which is distinguished from the products of human culture. Some philosophical naturalists have claimed that any attempt to distinguish nature from the (...) products of human culture in this way stems from a pre-Darwinian world view in which humans are conceived as being separate from and superior to the natural world. They suggest that this distinction involves an implicit denial of philosophical naturalism. Furthermore, J. Baird Callicott and others have argued that it contributes to environmental destruction by espousing human superiority over the natural world. To the contrary, the nature/culture distinction is not the cause of either of these offenses. It is consistent with philosophical naturalism, fundamental to our ordinary conception of nature, and useful in promoting environmental protection. (shrink)

I present three responses to a Rose Macualay quotation listing literary publications from 1901.

Abstract:The central problems of political philosophy (e.g., legitimate authority, distributive justice) mirror the central problems of business ethics. The question naturally arises: should political theories be applied to problems in business ethics? If a version of egalitarianism is the correct theory of justice for states, for example, does it follow that it is the correct theory of justice for businesses? If states should be democratically governed by their citizens, should businesses be democratically managed by their employees? Most theorists who have (...) considered these questions, including John Rawls inPolitical Liberalism, and Robert Phillips and Joshua Margolis in a 1999 article, have said “no.” They claim that states and businesses are different kinds of entities, and hence require different theories of justice. I challenge this claim. While businesses differ from states, the difference is one of degree, not one of kind. Business ethics has much to learn from political philosophy. (shrink)

David Marr provided a useful framework for theorizing about cognition within classical, AI-style cognitive science, in terms of three levels of description: the levels of (i) cognitive function, (ii) algorithm and (iii) physical implementation. We generalize this framework: (i) cognitive state transitions, (ii) mathematical/functional design and (iii) physical implementation or realization. Specifying the middle, design level to be the theory of dynamical systems yields a nonclassical, alternative framework that suits (but is not committed to) connectionism. We consider how a brain's (...) (or a network's) being a dynamical system might be the key both to its realizing various essential features of cognition — productivity, systematicity, structure-sensitive processing, syntax — and also to a non-classical solution of (frame-type) problems plaguing classical cognitive science.

According to an existing “environmental” narrative, the financial crisis of 2007-2009 was due in part to executive compensation packages in the financial services industry that incentivized excessive risk-taking. Also according to this narrative, those who have a duty to protect society – principally, government regulators, but also firms themselves – are open to blame for how executives were paid, and must take steps to change executive compensation. This narrative is important but incomplete. I offer a supplementary “agential” narrative. According to (...) this narrative, executives are open to blame for the financial crisis for taking socially excessive risks. Moreover, since executives can play a role in shaping their compensation, they have an obligation to ensure that it does not incentivize them to take such risks. (shrink)

Health institutions recommend that young infants be exclusively breastfed on demand, and it is widely held that parents who can breastfeed have an obligation to do so. This has been challenged in recent philosophical work, especially by Fiona Woollard. Woollard’s work critically engages with two distinct views of parental obligation that might ground such an obligation—based on maximal benefit and avoidance of significant harm—to reject an obligation to breastfeed. While agreeing with Woollard’s substantive conclusion, this paper (drawing on philosophical discussion (...) of the ‘right to rear’) argues that there are several more moderate views of parental obligation which might also be thought to ground parental obligation. We first show that an obligation to breastfeed might result not from a general obligation to maximally benefit one’s child, but from what we call ‘choice-specific’ obligations to maximise benefit within particular activities. We then develop this idea through two views of parental obligation—the Dual Interest view, and the Best Custodian view—to ground an obligation to exclusively breastfeed on demand, before showing how both these more moderate views fail. Finally, we argue that not only is there no general obligation to breastfeed children, but that it is often morally right not to do so. Since much advice from health institutions on this issue implies that exclusive breastfeeding on demand is the best option for all families, our argument drives the feeding debate forward by showing that this advice often misrepresents parents’ moral obligations in potentially harmful ways.

ABSTRACT:Debates about the ethics of executive compensation are dominated by familiar themes. Many writers consider whether the amount of pay CEOs receive is too large—relative to firm performance, foreign CEO pay, or employee pay. Many others consider whether the process by which CEOs are paid is compromised by weak or self-serving boards of directors. This paper examines the issue from a new perspective. I focus on the dutiesexecutives themselveshave with respect totheir owncompensation. I argue that CEOs’ fiduciary duties place a (...) moral limit on how much compensation they can accept, and hence seek in negotiation, from their firms. Accepting excessive compensation leaves the beneficiaries of their duties (e.g., shareholders) worse off, and thus is inconsistent with observing those duties. (shrink)

In In Contradiction, Graham Priest shows, as clearly as anything like this can be shown, that it is coherent to maintain that some sentences can be both true and false at the same time. As a consequence, some contradictions are true, and an appreciation of this possibility advances our understanding of the nature of logic and language.

“This commentary is a detailed and systematic examination of Kant’s Critique of Pure Reason designed for students of philosophy in their second and third year and anyone else similarly approaching Kant for the first time. Kant himself said of the first Critique, ‘It will be misjudged because it is misunderstood, and misunderstood because men choose to skim through the book and not to think through it – a disagreeable task, because the work is dry, obscure, opposed to all ordinary notions, (...) and moreover long-winded.’ It remains a work of the greatest interest and significance to modern analytical philosophers, and this commentary will help readers overcome the obstacles to ‘thinking through’ the book, as well it is hoped as making their task more agreeable.The author explains Kant’s elaborate technical terms and rhetorical idiosyncrasies. He relates Kant’s work to that of the great rationalist and empiricist philosophers. He shows how an understanding of the first Critique is relevant to modern epistemology, while distinguishing carefully between what Kant actually said and certain interesting views he inspired. Above all he sets out to stimulate his readers to a more profound examination of Kant and of Kantian problems.”- Publisher. (shrink)

This paper explores the view that there are such things as (nonexistent) fictional objects, and that we refer to such objects when we say things like "Sherlock Holmes is a fictional detective", or "Conan Doyle wrote about Sherlock Holmes".

Business ethicists have written much about ethical issues in employment. Except for a handful of articles on the very high pay of chief executive officers and the very low pay of workers in overseas sweatshops, however, little has been written about the ethics of compensation. This is prima facie strange. Workers care about their pay, and they think about it in normative terms. This article's purpose is to consider whether business ethicists' neglect of the normative aspects of compensation is justified. (...) I examine several possible justifications for neglecting compensation and show that they fail. What remains is a case for thinking that it is worthy of normative analysis. (shrink)

A cross-cultural empirical study is reported in this article which looks at ethical beliefs and behaviours among French and German managers, and compares this with previous studies of U.S. and Israeli managers using a similar questionnaire. Comparisons are made between what managers say they believe, and what they do, between managers and their peers' attitudes and behaviours, and between perceived top management attitudes and the existence of company policy. In the latter, significant differences are found by national ownership of the (...) company rather than the country in which it is situated. Significant differences are found, for both individual managers by nationality, and for companies by nationality of parents, in the area of organizational loyalty. The attitude towards accepting gifts and favours in exchange for preferential treatment, as a measure of societal values, is also found to show significant differences between national groups. However, no significant differences are found for measures for group loyalty, conflict between organizational and group loyalty and for conflicts between self and group/organization. The findings have implications for cross-border management decision strategies regarding such issues as receiving and giving of gifts, and the management of relations between local employees and international organizations which may be affected by differences in attitude to corporate loyalty.

Terence Irwin presents a historical and critical study of the development of moral philosophy over two thousand years, from ancient Greece to the Reformation. Starting with the seminal ideas of Socrates, Plato, and Aristotle, he guides the reader through the centuries that follow, introducing each of the thinkers he discusses with generous quotations from their works. He offers not only careful interpretation but critical evaluation of what they have to offer philosophically. This is the first of three volumes which (...) will examine the history of ethics in the Socratic tradition, up to the late 20th century. (shrink)
