Book excerpt: "Introduction: Effects of intended cutting angle (e.g., 30 ̊, 45 ̊, 90 ̊) on kinematics are well established. Studies have typically controlled for cut angle by omitting trials if a participant cuts more than 10 ̊ from the intended angle. However, the actual angle which the participant cuts to (i.e., executed cut angle, ECA) has rarely been measured and sufficiently controlled for. Understanding relationships between ECA and commonly measured biomechanical variables are necessary, as it may affect interpretation of previous results.Additionally, epidemiological research suggests an interaction effect whereby females are more likely to injure the anterior cruciate ligament of their non-preferred leg during non-contact circumstances. Understanding interaction effects of sex and leg preference in kinematics related to anterior cruciate ligament (ACL) injuries during cutting may offer explanation for such a phenomenon, given that cutting is a major source of such injuries in some sports. Objectives: 1a) To compare entry speed and ECA between sex and leg preference during unanticipated sidestep cutting in soccer players. 1b) To determine the relationships between ECA with peak hip and knee joint angles during unanticipated sidestep cutting in soccer players. 2) To determine if an interaction effect exists between sex and leg preference on peak hip and knee angles during unanticipated sidestep cutting in soccer players.Methods: 21 adolescent and adult male and female soccer players completed unanticipated running sidestep cuts to a prescribed 45 ̊ in both directions. Lower limb kinematics were attained via 3D motion capture. Hip and knee joint angles were calculated using a joint coordinate system, and peak angles were identified during the stance phase of cutting. Hierarchical linear modeling established relationships between peak hip/knee angles and ECA/ entry speed. Analysis of variances compared ECA between sex and leg preference. Interaction effects of sex and leg preference on peak hip/knee angles were analysed during the hierarchical linear modelling. Results: Higher ECAs were related to decreased knee flexion and valgus (i.e., more varus), and increased hip flexion and internal rotation (p range =

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Soccer has a high number of knee ligament ruptures. Sex and age are factors that have an impact on these injuries. One possible reason is that females have harmful movement patterns compared to males during activities such as cutting while running. The literature still lacks studies examining the influence of age on these movements. Therefore, research is needed to determine if sex and age have an impact on the movement patterns of soccer players. The primary objective of this study was to examine if sex and age impact the joint angles and inter-joint coordination during an unanticipated cutting task in soccer players. A secondary objective compared the strength, jump performance and dynamic balance of male and female soccer players of different age groups. The study recruited healthy soccer players of different age groups. This included 11 adolescents (five males, six females) and 11 adults (seven males, four females). A 12-camera three-dimensional motion capture system recorded joint angles while participants performed an unanticipated side-step cutting task. A hand-held dynamometer measured muscle torques. Hop tests measured jump performance and the modified Star Excursion Balance Test measured dynamic balance. Principal component analysis (PCA) identified differences in joint angles. Adult males presented greater changes in hip flexion at pre-contact compared to stance/take-off than adolescent males and adult females had lower changes than adolescent females. Females had lower changes in hip flexion, and lower hip abduction and ankle inversion angles. Adolescents had greater hip internal rotation and knee flexion angles, but lower changes in knee flexion angles at pre-contact compared to stance/take-off. For inter-joint coordination, females had a more out-of-phase pattern than males in the foot/shank segment in sagittal plane. In regard to clinical measures we observed a few differences in knee extensor torque and balance, with adolescents exhibiting better results. Clinicians and coaches should be aware that these characteristics might impair performance and increase injury risk"--

Book excerpt: Conventional theories of capitalism are mired in a deep crisis: after centuries of debate, they are still unable to tell us what capital is. Liberals and Marxists both think of capital as an ‘economic’ entity that they count in universal units of ‘utils’ or ‘abstract labour’, respectively. But these units are totally fictitious. Nobody has ever been able to observe or measure them, and for a good reason: they don’t exist. Since liberalism and Marxism depend on these non-existing units, their theories hang in suspension. They cannot explain the process that matters most – the accumulation of capital. This book offers a radical alternative. According to the authors, capital is not a narrow economic entity, but a symbolic quantification of power. It has little to do with utility or abstract labour, and it extends far beyond machines and production lines. Capital, the authors claim, represents the organized power of dominant capital groups to reshape – or creorder – their society. Written in simple language, accessible to lay readers and experts alike, the book develops a novel political economy. It takes the reader through the history, assumptions and limitations of mainstream economics and its associated theories of politics. It examines the evolution of Marxist thinking on accumulation and the state. And it articulates an innovative theory of ‘capital as power’ and a new history of the ‘capitalist mode of power’.

Available in PDF, EPUB and Kindle. Book excerpt: Includes a foreword by Major General David A. Rubenstein. From the editor: "71F, or "71 Foxtrot," is the AOC (area of concentration) code assigned by the U.S. Army to the specialty of Research Psychology. Qualifying as an Army research psychologist requires, first of all, a Ph.D. from a research (not clinical) intensive graduate psychology program. Due to their advanced education, research psychologists receive a direct commission as Army officers in the Medical Service Corps at the rank of captain. In terms of numbers, the 71F AOC is a small one, with only 25 to 30 officers serving in any given year. However, the 71F impact is much bigger than this small cadre suggests. Army research psychologists apply their extensive training and expertise in the science of psychology and social behavior toward understanding, preserving, and enhancing the health, well being, morale, and performance of Soldiers and military families. As is clear throughout the pages of this book, they do this in many ways and in many areas, but always with a scientific approach. This is the 71F advantage: applying the science of psychology to understand the human dimension, and developing programs, policies, and products to benefit the person in military operations. This book grew out of the April 2008 biennial conference of U.S. Army Research Psychologists, held in Bethesda, Maryland. This meeting was to be my last as Consultant to the Surgeon General for Research Psychology, and I thought it would be a good idea to publish proceedings, which had not been done before. As Consultant, I'd often wished for such a document to help explain to people what it is that Army Research Psychologists "do for a living." In addition to our core group of 71Fs, at the Bethesda 2008 meeting we had several brand-new members, and a number of distinguished retirees, the "grey-beards" of the 71F clan. Together with longtime 71F colleagues Ross Pastel and Mark Vaitkus, I also saw an unusual opportunity to capture some of the history of the Army Research Psychology specialty while providing a representative sample of current 71F research and activities. It seemed to us especially important to do this at a time when the operational demands on the Army and the total force were reaching unprecedented levels, with no sign of easing, and with the Army in turn relying more heavily on research psychology to inform its programs for protecting the health, well being, and performance of Soldiers and their families."

Available in PDF, EPUB and Kindle. Book excerpt: PERSONHOOD AND HEALTH CARE This book arose as a result of a pre-conference devoted to the topic held June 28, 1999 in Paris, France. The pre-conference preceded the Annual Congress of the International Academy ofLaw and Mental Health. Other chapters were solicited after the conference in order to more completely explore the relation of personhood to health care. The pre conference was held in honor of Yves Pelicier who led so many of our French colleagues in medicine, philosophy, and ethics as Christian Herve notes in his Tribute. As health care is aimed at healing persons, it is important to realize how difficult it is to construct a theory of personhood for health care, and thus, a theory of how healing in health care comes about or ought to occur. The book is divided into four parts, Concepts of the Person, Theories of Personhood in Relation to Health Care and Bioethics, Person and Identity, and Personhood and Hs Relations. Each section explores a critical arena in constructing the relation of personhood to health care. Although no exploration ofthis nature can be exhaustive, every effort was made to present both conflicting and complementary views of personhood from within similar and different philosophical and religious traditions. PART ONE: CONCEPTS OF THE PERSON Tracing the origins of the concept of person from antiquity through present day, Jean Delemeau provides an historical sketch of the development of a wide range of meanings.
