Scapula mobility complicates upper extremity kinematics assessment. Existing methods are diverse, providing inconsistent results. The current gold standard (bone pins) is prohibitively invasive. The purposes of the current study are to describe a virtual projection alternative to surface markers for video motion capture (VMC) of the scapula and to compare the results of the projection and surface marker methods to the results of similar existing methods. Ten participants were evaluated using VMC. Surface markers were applied to the trunk and arm (...) in accordance with existing guidelines. Three markers were affixed to plastic base on the skin over the acromion process. Other scapular landmarks were digitized in a neutral position. These landmarks’ locations were defined in reference to the acromion cluster and used to generate the projection. Humerothoracic, glenohumeral, and scapulothoracic kinematics were evaluated during shoulder abduction, flexion, and scaption. Joint angles produced by the surface markers and the projection were compared by Bonferroni-adjusted t tests. The results were compared to prior findings in the literature. The projection resulted in greater scapulothoracic upward rotation, internal rotation, and anterior–posterior tilt and less glenohumeral elevation (p <.0055) than did surface markers. The virtual scapula produced greater estimates of scapular mobility than did surface markers, corresponding to pre-existing results from similar methodologies. The result is a noninvasive measurement tool that produces different and superior results than do scapula surface markers. Measuring scapula kinematics via VMC without bone pins will facilitate future investigations into interactions between upper extremity injury, kinematics, and activity performance. (shrink)

Originally published in 1967. Representing the viewpoints of philosophers, psychologists, anthropologists, physicists, psychoanalysts, parapsychologists, psychiatrists and biologists, this volume discusses many aspects of ESP. The general theme is that the phenomena is very valid and can no longer be ignored.

We extend the theory of “Fine structure and iteration trees” to models having more than one Woodin cardinal.

Presenting some modern views on the problem of the nature of mind and its relationship to the brain, this book, published in 1965, brings together contributors from various disciplines which are affected by this issue. Coming from different philosophical outlooks as well as subjects, these contributors also comment on each other’s’ chapters with a view of developing thought on the approaches to the problem. The theory of mind-brain relationship is vital to human interest and has been in debate throughout western (...) thought over centuries, split mainly into dualist and monistic theories. These discussions had and still have wide impact philosophy, psychology, religion and cosmology, among other areas. (shrink)

The object of this paper is to explain a certain type of construction which occurs in priority proofs and illustrate it with two examples due to Lachlan and Harrington. The proofs in the examples are essentially the original proofs; our main contribution is to isolate the common part of these proofs. The key ideas in this common part are due to Lachlan; we include several improvements due to Harrington, Soare, Slaman, and the author.Our notation is fairly standard. If X is (...) an r.e. set, Xs is the finite set of elements enumerated in X before step s. if Ф is a recursive functional, Фs is the approximation to Ф at step s; it only queries the oracle about numbers xi and iless-than-or-equals, slantx; and right-pointing angle bracketx0,...,xk−1right-pointing angle bracket is an increasing function of each of its arguments. Sets are sometimes identified with their characteristic functions. Wj isthe jth r.e. set. Xc is the complement of X. (shrink)

Jeremy Bentham, the founder of utilitarianism, made a powerful impact on several major areas of thought and policy: ethics, jurisprudence, political and constitutional theory, and social and administrative reform. Yet from the start his ideas have been subject to misunderstanding and caricature. John Dinwiddy's Bentham is regarded as the best introduction to this important jurist and reformer. Dinwiddy examines the various components of Bentham's philosophy and shows how each was shaped by the radical rethinking entailed by the utilitarian approach. He (...) also discusses interpretations of Benthamism and its contemporary significance and the controversial question of Bentham's influence on reform. Bentham is reproduced here in full together with three classic essays that deal with key issues in understanding Bentham: his conversion to political radicalism, the relations between private and public ethics, and his theory of adjudication. A new introduction and select bibliography by William Twining set the context and survey the developments in Bentham studies since the book's original publication in 1989. (shrink)

The position of the United Methodist Church on end-of-life decisions is best described as intentional ambiguity or ambiguous intentions or both. The paper analyzes the official position of the denomination and then considers the actions of a U.M.C. bishop who served as a foreman for a trial of Dr. Jack Kevorkian. In an effort to find some common ground within an increasingly divided denomination, the work concludes with a consideration of the work of John Wesley and his approach to human (...) death. (shrink)
