Tax Exempt Religious Schools Under Attack: Conflicting Goals of Religious Freedom and Racial Integration
The Effect of Wrestling Training and Required Physical Education Upon the Physical Condition of College Students as Determined by the Rogers Strength Test and the Harvard Step Test
The improvement of athletics and physical education can only be brought about when the participating individuals strive to attain their optimum physical condition. There are numerous phases of physical condition. Some of the many functions of the human organism with which we are concerned when striving for optimum physical condition are: respiratory, cardiovascular, nervous, and muscular. A student of physiology understands that all functions of the human body are equally vital to the maintenance of life and health. This statement is undoubtedly true. If we look at the field of physical education and athletics we see that certain functions of the body are more important to the attainment of the objectives than are others. For example, an artist would place more of a premium on a conditioned nervous system than a conditioned cardiovascular system capable of pumping great quantities of blood through the body. It would seem that the athlete and physical education student would need most of all an outstanding cardiovascular and muscular system to approach the goals set up for them. This thesis has, therefore, been set up to study methods of improving these functions of the human body through various types and degrees of training. This study describes some of the many activities and procedures that could be used to develop and improve the muscular and cardiovascular systems of an individual. The purpose of this study is to ascertain the degree and speed with which wrestler training will develop these areas. Throughout the report other sports and physical education activities enter the picture and help to recognize the cause of a specific physiological phenomenon. However, it must be kept in mind that the major conclusions will be drawn from the effects of wrestling. To study wrestling as a means of improving and developing strength and circulation is the major purpose of this thesis
Improving meson two-point functions in lattice QCD
We describe and test a method to compute Euclidean meson two-point functions
in lattice QCD. The contribution from the low-lying eigenmodes of the Dirac
operator is averaged over all positions of the quark sources. The contribution
from the higher modes is estimated in the traditional way with one or a few
source points per lattice. In some channels, we observe a significant
improvement in the two-point functions for small quark masses.Comment: 10 pages, 7 figure
The public sphere as a dynamic network
This article proposes to conceptualize the public sphere as a dynamic network of actors and contents that are linked with each other by communicative actions. This perspective allows us to theoretically derive and empirically describe the entire range of small to large network structures and their evolution over time. First, we will define the elements of these networks, which include the actors, content, communicative actions, and content relations. Based on these entities, four communicative roles (producer, recipient, curator, isolate) will be distinguished. Second, we will summarize how these actors perceive the communicative situation and how they select from behavioral options. Third, we will show how this combines with the network dynamics and outcomes that are discussed in the different lines of research. This provides not only the basis for understanding the link between the communicative actions on the micro-level and macro-level structures, but also new avenues for normative discussions
Farming for Health: Aspects from Germany
Until now, the term ‘Farming for Health’ is unknown in Germany but it would cover a wide spectrum of different kinds of social agriculture already existing in Germany, such as farms that integrate disabled people or drug therapy into their farming system, or farms that integrate children, pupils or older people. Relevant work in Germany is done in ‘Sheltered Workshops’, where supporting and healing powers of farming and gardening are used for disabled people with a diversity of work possibilities. Relevant activities also take place in work-therapy departments using horticultural therapy and in animalassisted therapy. There are an estimated number of 1000 different projects for mentally ill, disabled and elderly people in hospitals, Sheltered Workshops, on farms and other projects in Germany with a multitude of individual work places.
The upcoming idea of Farming for Health may be met by the term ‘multifunctionality’ as one of the future goals of agriculture: to combine the production of cash crops with social functions, like providing space for recreation, care for landscapes and care for disabled people. Research showed that farms that work together with clients in their farming system have more time and financial support to integrate aims like caring for biotopes and landscape measures into their work schedule
The Analysis of Space-Time Structure in QCD Vacuum II: Dynamics of Polarization and Absolute X-Distribution
We propose a framework for quantitative evaluation of dynamical tendency for
polarization in arbitrary random variable that can be decomposed into a pair of
orthogonal subspaces. The method uses measures based on comparisons of given
dynamics to its counterpart with statistically independent components. The
formalism of previously considered X-distributions is used to express the
aforementioned comparisons, in effect putting the former approach on solid
footing. Our analysis leads to definition of a suitable correlation coefficient
with clear statistical meaning. We apply the method to the dynamics induced by
pure-glue lattice QCD in local left-right components of overlap Dirac
eigenmodes. It is found that, in finite physical volume, there exists a
non-zero physical scale in the spectrum of eigenvalues such that eigenmodes at
smaller (fixed) eigenvalues exhibit convex X-distribution (positive
correlation), while at larger eigenvalues the distribution is concave (negative
correlation). This chiral polarization scale thus separates a regime where
dynamics enhances chirality relative to statistical independence from a regime
where it suppresses it, and gives an objective definition to the notion of
"low" and "high" Dirac eigenmode. We propose to investigate whether the
polarization scale remains non-zero in the infinite volume limit, in which case
it would represent a new kind of low energy scale in QCD.Comment: v2: 38 pages, 12 figures, author-preferred version; v3:

Another determination of the quark condensate from an overlap action
I use the technique of Hernandez, et al (hep-lat/0106011) to convert a recent
calculation of the lattice-regulated quark condensate from an overlap action to
a continuum-regulated number. I find Sigma(MSbar)(mu = 2 GeV) = (282(6)
MeV)-cubed times (a-inverse/1766 MeV)-cubed from a calculation with the Wilson
gauge action at beta=5.9.Comment: 3 pages, Revtex, 1 postscript figure. References added. COLO-HEP-47
The digital transformation of knowledge order: a model for theanalysis of the epistemic crisis
In a proclaimed age of ‘post-truth,’ scholars have raised concerns about the spread of false information and the questioning of epistemic authorities. In this paper, we develop an analytical model to capture the digital transformation of knowledge order. Drawing on insights from social epistemology, sociology and history of knowledge, and media history, we identify epistemic practices as basic elements of knowledge order. We then analyze how epistemic practices are organized into an overarching structure of knowledge phases, contexts, roles, and hierarchies. Digital media tend to destabilize the traditional knowledge order. This destabilization is characterized by a more flexible order of phases, a dissolution of boundaries between contexts, an opening of professional roles to new actors, and a flattening of hierarchies
Liver transplantation for alcoholic cirrhosis: Long term follow-up and impact of disease recurrence
Background. Alcoholic liver disease has emerged as a leading indication for hepatic transplantation, although it is a controversial use of resources. We aimed to examine all aspects of liver transplantation associated with alcohol abuse. Methods. Retrospective cohort analysis of 123 alcoholic patients with a median of 7 years follow-up at one center. Results. In addition to alcohol, 43 (35%) patients had another possible factor contributing to cirrhosis. Actuarial patient and graft survival rates were, respectively, 84% and 81% (1 year); 72% and 66% (5 years); and 63% and 59% (7 years). After transplantation, 18 patients (15%) manifested 21 noncutaneous de novo malignancies, which is significantly more than controls (P=0.0001); upper aerodigestive squamous carcinomas were over-represented (P=0.03). Thirteen patients had definitely relapsed and three others were suspected to have relapsed. Relapse was predicted by daily ethanol consumption (P=0.0314), but not by duration of pretransplant sobriety or explant histology. No patient had alcoholic hepatitis after transplantation and neither late onset acute nor chronic rejection was significantly increased. Multiple regression analyses for predictors of graft failure identified major biliary/vascular complications (P=0.01), chronic bile duct injury on biopsy (P=0.002), and pericellular fibrosis on biopsy (P=0.05); graft viral hepatitis was marginally significant (P=0.07) on univariate analysis. Conclusions. Alcoholic liver disease is an excellent indication for liver transplantation in those without coexistent conditions. Recurrent alcoholic liver disease alone is not an important cause of graft pathology or failure. Potential recipients should be heavily screened before transplantation for coexistent conditions (e.g., hepatitis C, metabolic diseases) and other target-organ damage, especially aerodigestive malignancy, which are greater causes of morbidity and mortality than is recurrent alcohol liver disease
