Introduction: Physical distancing under the coronavirus disease 2019 pandemic had a significant impact on lifestyles, including exercise routines. In this study, we examined the relationship between mental health and addictive behaviors, such as excessive exercise and the use of image and performance enhancing drugs across 12 sport disciplines.Materials and methods: A large cross-sectional sample of the adult population was surveyed. The mean age was 33.09. The number of male participants was 668. The use of IPEDs was assessed in conjunction with (...) psychometric measures such as the Exercise Addiction Inventory and the Appearance Anxiety Inventory. The participants were grouped into activity group and non-activity group according to the presence or absence of their exercise habits. The results were compared between these groups, as well as across sport disciplines, while taking into account the relationship between different psychological measures and IPEDs consumption.Results: The frequency of IPEDs use was higher among AG than NAG, although AG participants reported less history of addictions than NAG. The logistic regression analysis revealed that scores equal to or above cutoff points, in both the EAI and AAI, predicted the IPEDs use. Regarding the differences across the various sport disciplines, those who were involved in practicing Weight Lifting and Cross Fit were found to be more at risk of excessive exercising and more inclined to use a wide range of IPEDs.Conclusions: Although exercise could help to increase well-being and prevent addictions during the COVID-19 pandemic, our results show that those in the AG are particularly vulnerable to excessive IPEDs use. Sport disciplines associated with higher EAI and AAI scores have also shown a higher tendency to excessive IPEDs use. Furthermore, the factor of having above the cutoff scores in EAI or AAI in each sport could indicate larger IPEDs consumption regardless of the discipline. In light of the current findings, it is necessary to better define the “non-excessive” levels of exercise in various sport disciplines and an adequate intake of IPEDs to ensure the safety and well-being of people during a pandemic.

Hypotheticals, conditionals, and their connecting relation, implication, dramatically changed their meanings during the nineteenth and early part of the twentieth century. Modern logicians ordinarily do not distinguish between the terms hypothetical and conditional. Yet in the late nineteenth century their meanings were quite different, their ties to the implication relation either were unclear, or the implication relation was used exclusively as a logical operator. I will trace the development of implication as an inference operator from these earlier notions into the (...) first third of the twentieth century using as the starting point the ideas primarily of R. Whately and W. Hamilton before discussing the work of the transitional logicians, A. De Morgan and G. Boole on these topics. Then we discuss the relevant views of four prominent but relatively unknown nineteenth century British logicians, W.E. Johnson, J.N. Keynes, E.E.C. Jones, and H. MacColl, as well as those of the more influential logicians, W.S. Jevons and J. Venn, closing with a section on ‘implication as inference’ where we explore some key ideas of B. Russell and sketch the work of D. Hilbert, P. Hertz, and G. Gentzen who together are responsible for the development of the modern ideas related to the subjects of this paper. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 42.2 (2004) 231-232 [Access article in PDF] Donald R. Kelley. The Descent of Ideas: The History of Intellectual History. Aldershot, England: Ashgate, 2002. Pp. vii + 320. Cloth, $59.50. The field of intellectual history, once known as the history of ideas, intersects with many other historical sub-disciplines, especially the history of philosophy, the history of literature, the history of science, and cultural history. (...) Donald Kelley, a distinguished intellectual historian and editor of The Journal of the History of Ideas, has written a comprehensive history of his field that emphasizes the process by which scholars who studied the history of thought gradually adopted an approach to their subject that resulted in "the descent of ideas" from philosophical abstraction to the "sublunar" realm of human experience and understanding. This intellectual descent, just like the biological descent of man plotted by Darwin in 1871, has not followed a linear course. Displaying remarkable scholarly range and erudition, Kelley guides the reader through a complex and sometimes amorphous history of intellectual history that covers developments in scholarship from ancient times to the present.The most original and distinctive feature of the book is Kelley's emphasis on the importance of eclecticism in the emergence of intellectual history. The book begins with an exposition of the scholarship of the early nineteenth-century Liberal French philosopher and educator Victor Cousin, whose eclectic approach to teaching the history of philosophy was for him not only the best route to attaining true wisdom but also the key to organizing the history of thought. In this way Cousin helped to make intellectual history a distinct branch of historical scholarship, while his contemporaries Abel-François Villemain and François Guizot marked a parallel shift in interest from the history of ideas to the history of literature and the history of civilization. From this starting point Kelley looks back to classical, medieval, and early modern thought, exploring earlier expressions of eclecticism, including that of Diogenes Laertius in the third century CE, as a distinct and often maligned philosophical tradition. An excellent chapter on the "new" or modern eclecticism of the seventeenth and eighteenth centuries, which rejected syncretism as well as skepticism and which found a place for Christian thought, gives new significance to the work of [End Page 231] Jakob Thomasius, his son Christian Thomasius, and J. J. Brucker, whose Critical History of Philosophy (1742-44) established the history of philosophy as a distinct discipline.Kelley devotes considerable space to discussing the intersection between the history of philosophy and intellectual history. The former has long served as the "taproot" of the latter, even after eighteenth-century philosophers, striving to establish philosophy as a rigorous science, rejected a historical approach to attaining wisdom. This development caused a split within the ranks of philosophers between the "purists" in the Kantian tradition and "culturalists" like J. G. Herder who, "following the descent of ideas into the medium of language, strayed off into what came to be known as cultural history" (p. 4). In a chapter devoted to the history of philosophy in modern times, Kelley explores the contributions made by the philosophers Ernst Cassirer, Benedetto Croce, and Arthur Lovejoy to the field of intellectual history.By taking a long historical perspective on the development of his field, Kelley is able to demonstrate that some recent trends in intellectual and literary history have longstanding precedents. Thus he traces the recent "linguistic turn" in historical analysis, which he styles the "linguistic return," back to the Renaissance, and he sees the claims of twentieth-century scholars who emphasize the importance of narrative structures in giving meaning to the past as restatements of ancient literary theory. In his chapter, "The Way of Ideas and the Ways of Words," Kelley shows that the descent of ideas began long before the emergence of intellectual history as a distinct field. As might be expected in a work of historiography, Kelley's methodology in establishing these precedents and continuities in scholarship is in a certain sense traditional. Yet there is little that...

Health care professionals often face moral dilemmas. Not dealing constructively with moral dilemmas can cause moral distress and can negatively affect the quality of care. Little research has been documented with methodologies meant to support professionals in care for the homeless in dealing with their dilemmas. Moral case deliberation is a method for systematic reflection on moral dilemmas and is increasingly being used as ethics support for professionals in various health-care domains. This study deals with the question: What is the (...) contribution of MCD in helping professionals in an institution for care for the homeless to deal with their moral dilemmas? A mixed-methods responsive evaluation design was used to answer the research question. Five teams of professionals from a Dutch care institution for the homeless participated in MCD three times. Professionals in care for the homeless value MCD positively. They report that MCD helped them to identify the moral dilemma/question, and that they learned from other people’s perspectives while reflecting and deliberating on the values at stake in the dilemma or moral question. They became aware of the moral dimension of moral dilemmas, of related norms and values, of other perspectives, and learned to formulate a moral standpoint. Some experienced the influence of MCD in the way they dealt with moral dilemmas in daily practice. Half of the professionals expect MCD will influence the way they deal with moral dilemmas in the future. Most of them were in favour of further implementation of MCD in their organization. (shrink)

This book has been prompted by the dishonesty of much contemporary treatment of the Bible. It is not a 'debunking' of the Bible, but an attempt to show what qualities and what preliminary assumptions are needed for the Bible to be genuinely understood and interpreted. Honest scholarship and honest interpretations must acknowledge that a revolution has taken place in the understanding of the Bible during the last two hundred years and that to try to deny or play down or disguise (...) the results of this revolution is to be faithful neither to God nor to ourselves. With that conviction, and with their customary panache, the authors then go on to look at the facts about the Bible; the New Testament interpretation of scripture; the interpretation of the Bible in the early church; historical criticism; fundamentalism; and prophecy. 'They analyse the books of the Bible, examine the canon and the Bible as norm and as the church's book, consider the role of faith and conclude with a chapter 'In Praise of the Bible'. Here, in the last book together, the Professors Hanson are indeed on top of their form. (shrink)

Type theory is a fast-evolving field at the crossroads of logic, computer science and mathematics. This gentle step-by-step introduction is ideal for graduate students and researchers who need to understand the ins and outs of the mathematical machinery, the role of logical rules therein, the essential contribution of definitions and the decisive nature of well-structured proofs. The authors begin with untyped lambda calculus and proceed to several fundamental type systems culminating in the well-known and powerful Calculus of Constructions. The book (...) also covers the essence of proof checking and proof development, and the use of dependent type theory to formalize mathematics. The only prerequisites are a good knowledge of undergraduate algebra and analysis. Carefully chosen examples illustrate the theory throughout. Each chapter ends with a summary of the content, some historical context, suggestions for further reading and a selection of exercises to help readers familiarize themselves with the material.

“These fragments I have shored against my ruins.”.

Understanding of organizational ethics phenomena requires complex understanding of organizational practices in their real world contexts. We can try to understand and build theory about these complex real world practices from the points of view of: a traditional deductive, ethics literature-based, literature gap formulation approach; or, an inductive, practitioner-based literature gap formulation approach. This consideration of inductive, practitioner-based versus deductive, literature-based literature gap formulation is related to the discussion concerning “engaged scholarship” and relationships and gaps between theory and practice in (...) organization studies [Van De Ven, 2007, Engaged Scholarship: A Guide for Organizational and Research Knowledge ]. However, there is an important difference with respect to the key issue of ethics literature versus practitioner-based literature gap formulation. This article offers examples of the two different approaches and makes comparisons between them. Implications for practice-based organizational ethics theory building, Ph.D. education, and public intellectual work are considered. (shrink)
