This study compared 30 older musicians and 30 age-matched non-musicians to investigate the association between lifelong musical instrument training and age-related cognitive decline and brain atrophy. Although previous research has demonstrated that young musicians have larger gray matter volume in the auditory-motor cortices and cerebellum than non-musicians, little is known about older musicians. Music imagery in young musicians is also known to share a neural underpinning [the supramarginal gyrus and cerebellum] with music performance. Thus, we hypothesized that older musicians would (...) show superiority to non-musicians in some of the abovementioned brain regions. Behavioral performance, GMV, and brain activity, including functional connectivity during melodic working memory tasks, were evaluated in both groups. Behaviorally, musicians exhibited a much higher tapping speed than non-musicians, and tapping speed was correlated with executive function in musicians. Structural analyses revealed larger GMVs in both sides of the cerebellum of musicians, and importantly, this was maintained until very old age. Task-related FC analyses revealed that musicians possessed greater cerebellar-hippocampal FC, which was correlated with tapping speed. Furthermore, musicians showed higher activation in the SMG during MWM tasks; this was correlated with earlier commencement of instrumental training. These results indicate advantages or heightened coupling in brain regions associated with music performance and imagery in musicians. We suggest that lifelong instrumental training highly predicts the structural maintenance of the cerebellum and related cognitive maintenance in old age. (shrink)

Intervention studies on sedentary older adults have demonstrated that commencing physical exercise at an older age has a positive effect on brain structure. Although this suggests that older athletes with lifelong sports training have larger gray matter volume in some brain regions compared to age-matched non-athletes, evidence in the literature is scarce. Moreover, it remains unclear whether a larger GMV is associated with training intensity or period of training in life. To address these gaps in the literature, we compared regional (...) brain GMV between 24 older athletes and 24 age-matched non-athletes. The period of sports training and the current training time of the athletes were assessed. Both groups were evaluated for physical activity intensity as well as cognitive and motor performance. Although no group differences were noted in cognitive and motor performance, athletes reported higher physical activity intensity than non-athletes. Whole-brain structural analysis revealed a significantly larger GMV in several brain regions in athletes. Notably, the GMV of the precuneus in athletes was positively correlated with earlier commencement of sports training and training duration but was negatively correlated with current training time. Our findings demonstrate that early-commenced and continued sports training predicts structural maintenance of the precuneus in old age. Our results also suggest that excessive training time in old age may have a negative impact on the GMV of the precuneus; thereby delineating how the precuneus is associated with lifelong sports training in older athletes.

The study aimed to identify the relationship between correcting the deviations in the measurement of performance and achieving the objectives of control and the performance of the job at the Islamic University in the Gaza Strip. To achieve the objectives of the research, the researchers used the descriptive analytical approach to collect information. The questionnaire consisted of (20) statements distributed to three categories of employees of the Islamic University (senior management, faculty members, their assistants and members of the administrative board). (...) A random sample of 314 employees was selected and 276 responses were retrieved with a recovery rate of 88.1%. The Statistical Analysis Program (SPSS) was used to enter, process, and analyze the data. The results of the study showed a positive relationship between correcting deviations in performance measurement and achieving the control objectives represented by the functional performance in the Islamic University from the point of view of the members (senior management, faculty and their assistants, and the administrative board), where the relative weight of all the paragraphs was (74.25%). The study recommended the need to ensure that the actual performance of the planned performance is matched and decisions are taken to correct the serious deviations and take the necessary measures in terms of retraining and change in regulations, wages and bonuses and punishment of the culprit, neglect and negligence by mistake.

Abe Kobo (1924-1993) was one of Japan's greatest postwar writers, widely recognized for his imaginative science fiction and plays of the absurd. However, he also wrote theoretical criticism for which he is lesser known, merging literary, historical, and philosophical perspectives into keen reflections on the nature of creativity, the evolution of the human species, and an impressive range of other subjects. Abe Kobo tackled contemporary social issues and literary theory with the depth and facility of a visionary thinker. Featuring twelve (...) essays from his prolific career--including "Poetry and Poets (Consciousness and the Unconscious)," written in 1944, and "The Frontier Within, Part II," written in 1969--this anthology introduces English-speaking readers to Abe Kobo as critic and intellectual for the first time. Demonstrating the importance of his theoretical work to a broader understanding of his fiction--and a richer portrait of Japan's postwar imagination--Richard F. Calichman provides an incisive introduction to Abe Kobo's achievements and situates his essays historically and intellectually. (shrink)

Abed Azzam offers a fresh interpretation of Nietzsche's engagement with the work of Paul the Apostle, reorienting the relationship between the two thinkers while embedding modern philosophy within early Christian theology. Paying careful attention to Nietzsche's dialectics, Azzam situates the philosopher's thought within the history of Christianity, specifically the Pauline dialectics of law and faith, and reveals how atheism is constructed in relation to Christianity. Countering Heidegger's characterization of Nietzsche as an anti-Platonist, Azzam brings the philosopher closer to Paul through (...) a radical rereading of his entire corpus against Christianity. This approach builds a compelling new history of the West resting on a logic of sublimation, from ancient Greece and early Judaism to the death of God. Azzam discovers in Nietzsche's philosophy a solid, tangible Pauline structure and virtual, fragile Greek content, positioning the thinker as a forerunner of the recent "return to Paul" led by Badiou, Agamben, Žižek, and Breton. By changing the focus of modern philosophical inquiry from "Nietzsche and philosophy" to "Nietzsche and Christianity," Azzam initiates a major challenge to the primacy of Plato in the history of Western philosophy and narrow certainties regarding Nietzsche's relationship to Christian thought.

In “Justice at the Margins: The Social Contract and the Challenge of Marginal Cases” (Southern Journal of Philosophy, 55.1), Nathan Bauer and David Svolba appeal to a concept of recognition found in social contract theory to argue that all humans, including humans who lack certain unique cognitive abilities, so‐called marginal cases, have rights that nonhuman animals lack. The main reason is that we can recognize ourselves in all humans, but not in nonhuman animals. I argue (i) that it is unclear (...) that we can recognize ourselves in certain types of marginal cases, such as corpses and embryos; (ii) that Bauer and Svolba’s reason for why we cannot recognize ourselves in nonhuman animals is questionable; and (iii) if we can recognize ourselves in any types of marginal cases, then we should be able to recognize ourselves in nonhuman animals.

Storsletten and Jakobsen (2015) try to integrate the instrumental, responsible, and spiritual positions in leadership studies with Kierkegaard’s aesthetic, ethical, and religious modes of existence. Their combination of leadership theory and Kierkegaardian thought, however, seems deeply problematic. In particular, the instrumental-aesthetic and responsible-ethical connections appear weak or at least significantly underdeveloped, and the spiritual-religious connection seems logically inconsistent.

Since its inception, Stakeholder Management Capability (SMC) has constituted a powerful hermeneutic through which business organizations have understood and leveraged stakeholder relationships. On this model, achieving a high level of capability largely depends on managerial ability to effectively bargain with stakeholders and establish solidarity vis-à-vis the successful negotiation, implementation, and execution of "win–win" transactional exchanges. Against this account, it is rightly pointed out that a transactional explanation of stakeholder relationships, regarded by many as the bottom line for stakeholder management, fails (...) to provide managerial direction regarding how to resolve a variety of normative stakeholder claims that resist commoditization. In response to this issue, this paper has two overlapping goals. It seeks to elaborate a discourse theoretical approach to the problem by first drawing out Jurgen Habermas’ theory of communicative action and delineating the various types of rational discourse. Second, the paper attempts to present concrete implications for SMC relative to reshaping the contours of rational, process, and transactional analysis in light of central discourse theoretical conclusions.

This volume concludes the two-volume sequel to Masao Abe's Zen and Western Thought. Like its companion, Buddhism and Interfaith Dialogue, this work contains many previously published essays and papers by Abe. Here he clarifies the true meaning of Buddhist emptiness in comparison with the Aristotelian notion of substance and the Whiteheadean notion of process.

The etiology of schizophrenia remains heavily contested despite extensive research, huge quantities of data, and heavy investment in time and material resources around the world. Not only is there little agreement about the causes of this most devastating of psychiatric conditions, but there is disagreement as to whether the condition exists at all as a coherent entity (Bentall 2006). Evolutionary theorists have had the added problem of explaining how a severe mental illness that causes a significant reproductive disadvantage can continue (...) to exist in human populations, where it is claimed to have a uniform prevalence across the world. Many Darwinian formulations have suggested various forms of tradeoffs where the .. (shrink)

In The Face of Emotions, which was Carroll Izard’s first major attempt at elaborating his differential emotions theory (DET), he stated that the book “presents a theoretical framework for the study of emotions and their role in personality and interpersonal processes.” Yet, over the years, his contribution to personality theory has generally been overshadowed by the attention focused on his views on facial expressions and the structure of emotions. This article will begin with a brief overview of the DET perspective (...) on personality development. Then, it will examine how the DET framework can be used to organize recent findings from three lines of research on adult personality. It will conclude with suggestions for future research as well as some personal recollections. (shrink)

Maybe God doesn’t have to do anything in order to bring it about that there be light. Most of us, however, have to perform some sort of act like flicking a switch to do so. But some of the things we bring about do not require such mediating acts. For example, it appears that I don’t have to do anything in order to bring about or cause the arm movements I perform in flicking the switch. I just move my arm. (...) Of course, a number of things will happen when I move my arm: neurons fire, muscles flex. But these are not acts in and of themselves. The only act we have here is the moving of the arm. So my arm movement in this instance is basic in a sense in which my illumination of the room is not. (shrink)

This collection of Abe's essays is a welcome addition to philosophy and comparative philosophy.

The term ‘sporting integrity’ is widely used in the normative assessment of sports. The term, however, suffers from a lack of conceptual precision. Alfred Archer’s ‘coherence-view’ of sporting integrity goes a long way to help clarify what ‘sporting integrity’ actually means and the specific institutional and individual obligations that it generates. Archer argues that ‘sporting integrity’ essentially means that the constraints athletes face ‘cohere’, in the sense of applying consistent inefficiencies between athletic competitors. For example, those who use performance enhancing (...) drugs are less constrained than those who do not use PEDs, and thus PED use undermines sporting integrity. This paper presents the argument that over and above competitive coherence, sporting integrity means living up to the ‘spirit’ or ‘ethos’ of a game. The implications of this view are that a sport could have ‘coherent’ competitive constraints and still lack sporting integrity; additionally, a sport could have ‘i... (shrink)

This paper describes and argues for the inclusion of a modified form of Venn diagrams in critical thinking courses and textbooks. The modified Venn Diagrams, it is argued, are easier to learn as they more clearly show the meanings of inclusion and exclusion, easier to use when solving problems (including those found on LSAT exams), are often included in LSAT preparatory material, and students tend to have a more thorough understanding of the concept of logical possibility after having used modified (...) Venn diagrams. (shrink)

The first century B.C. poet Lucretius put forth an argument for why death is not bad for the person who has died. This argument is commonly referred to as Lucretius’s “symmetry argument” because of its assumption that the period before we were born is symmetrical to the period after we die. Jeremy Simon objects to the symmetry argument, claiming that the two periods are not relevantly symmetrical: being born earlier than we actually are born would not guarantee us more life, (...) whereas extending our lifespan past the time we actually would die would guarantee us more life. Simon believes this difference between the two time periods also explains why it is reasonable for people to wish for a later death but not for an earlier birth. We raise several objections to Simon’s response. Our main objection is that insofar as people do not wish for an earlier birth, it is not because they fear losing more life, but rather is a result of being concerned about losing what is important about life, namely its unique content.

“Collective impact problems” refer to situations where there is a collective harm or benefit, but where no single action seems to make a difference one way or the other. Collective impact problems arise when considering several pressing ethical issues in business, such as shareholder and consumer activism, business and climate change, factory farming and animal welfare, fair-trade and sweatshop labor, and corporate philanthropy. Unfortunately, business ethics textbooks do not explicitly deal with collective impact problems and, as such, students may be (...) lacking the theoretical and practical skills necessary to deal with issues of significant moral concern. This paper helps to address this gap by introducing the reader to some collective impact cases in business ethics, detailing the challenges that collective impact problems pose for consequentialist and non-consequentialists alike, and highlighting some of the promising pedagogical benefits of using collective impact cases in a business ethics class.

Written by one of Japan's foremost contemporary thinkers and scholars, Zen and Modern Society is the third in a series of essay collections on Zen Buddhism as seen in the context of Western thought. Throughout his career, Masao Abe has articulated the meaning of Zen thought in a uniquely compelling way - at once, true to the original tradition and appropriately relevant to a variety of comparative standpoints, ranging from Biblical Judeo-Christianity to modern existentialism, phenomenology, and postmodernism. As a leading (...) representative of the Kyoto School, which has sought a critical, comparative linking of Eastern and Western thought, Abe has based his approach on constructive, mutually respectful yet critical intellectual interaction and dialogue with some of the leading figures in the West (including Paul Tillich, Hans Kung, and Eugene Borowitz) as well as dozens of colleagues, students, and disciples. Together with the previous volumes, this work examines and exemplifies some key features of Kyoto School thought. While the essays presented here should be read in light of the socio-political criticism that has since been lodged against the Kyoto School and, more particularly, i. (shrink)

The hazard of postharvest pest losses is ubiquitous in peasant farming systems; as a result, farmers invariably have some response to the threat of these losses. Responses to postharvest pests may be more extensive than to field pests, even when, by statistical measures, the usual levels of losses are comparable. In studies of pest management practices in three contrasting areas in Kenya, it was found that farmers virtually always rely on an array of techniques and strategies, usually including both older (...) and more modern practices. There is considerable variation among regions in the techniques used, due not only to climatic and socioeconomic factors, but also to variations in cultural history and preferences. The ways in which management practices have changed over time also vary by region. The major changes have been related to overall system change. Four main sources of change have been paramount: (1) population growth and the intensification of land use; (2) the introduction of new cash crops; (3) the introduction of new marketing infrastructure; and (4) the perception of increased environmental risk. Their effect on the replacement of older practices by newer ones is often interrelated. Traditional techniques are often based on materials derived from bushland, but increasing population density makes these difficult to continue as bushland and its common property resources disappear. Simultaneously, tolerance for losses is reduced as land availability is constrained. With the introduction of a cash crop infrastructure, new methods of pest management, especially pesticide use, become more readily available and may spread rapidly. Areas with good market infrastructure but varying population density may still differ considerably because with abundant land it is possible to compensate for expected losses by additional planting.A study of an FAO project to improve postharvest management through earlier harvesting and a redesigned storage crib indicate some reasons for its lack of widespread acceptance. Little or no attempt was made to adapt techniques to varying circumstances; instead, a single “solution” was meant to be applied across areas of vastly different conditions. In many cases, this project represented a radical response to a problem farmers considered they were coping with acceptably using existing methods. Although it probably represents an improvement over traditional storage methods in purely technical terms, the new technique also often involved major costs, readjustments, and cultural disruptions that may not have been anticipated by its designers. More likely to succeed would be a strategy that begins with some of farmers' existing practices and whose objective is to develop and offer a range of possible improvements from which farmers could select individual components appropriate to their conditions and needs.
