Stress inoculation education and counseling with patients on hemodialysis : effects on psychosocial stressors and adherence

The purposes of this study were to (a) investigate the effects of the cognitive-behavioral intervention of Stress Inoculation Education (SIE) and counseling on anxiety, depression, psychosocial adjustment to illness, perception of hemodialysis stressors, and adherence to the medical regimen, and to (b) examine the relationship of psychosocial reactions and adherence to physiological problems while on hemodialysis. Two intervening variables, interpersonal support and control, were examined to determine their influence on adherence to the medical regimen and psychosocial variables. While physical and physiological demands of hemodialysis are universal, psychosocial responses to these demands are unique. Hemodialysis requires multiple and radical lifestyle changes and the anxiety and depression experienced by many patients justify the need for examining interventions to assist with the patient's adjustment. A single-subject experimental design with multiple, repeated measures was used. Six subjects between the ages of 30 and 47, who had been on hemodialysis at least 6 weeks but not longer than 3 months, participated in six sessions of the intervention. SIE, based on the transaction model of stress as a relationship between person and environment, has three phases; i.e., conceptualization phase, skills acquisition and rehearsal phase, and application and follow-through phase

A history of the department of physical education at Winthrop College, 1886-1970

It was the objective of this study to construct a historical narrative concerning the origin and development of the physical education program at Winthrop College, Rock Hill, South Carolina. Winthrop, the South Carolina College for Women, was founded in 1886. Physical education has always been included in the college curriculum. The Department of Physical Education was formally established in 1910 and a professional preparation program was initiated in 1919. After materials related to the topic had been located and examined, eleven questions were formulated as a guide for further research. The questions were concerned with the establishment of the college, the origin of its physical education program, the beginning of the professional preparation program, the facilities occupied by the Department of Physical Education, the influence of national trends on the program, and outstanding persons in the history of the department. The material assembled in the process of answering these questions was synthesized into a narrative which provided a reconstruction of past events relating to the Department of Physical Education at Winthrop College

A man in a woman's world: male support networks in women's flat track roller derby

Is modern women’s roller derby a form of feminism, and what role do men play within it? I propose that women’s roller derby is born out of radical feminism, while male volunteers and supporters act as important nodes in broad support networks. In this article, I examine the history of male supporters of women’s movements as well as feminist perspectives of Title IX and women’s sport. I then contrast the findings with survey and interview data from a women’s roller derby league from the east coast. As roller derby’s revival exemplifies radical feminism as sport, survey respondent’s views on roller derby as a women’s movement correlated with their level of active involvement with the league. The interviewed athletes, volunteers, and fans, however, were primarily interested in roller derby as an athletic outlet and not as a form of feminist expression. Regardless of their view on derby as a women’s movement, the majority of respondents had positive reactions towards male involvement, and understood that they played important roles in creating the league’s formal and informal support networks. While roller derby allowed women’s gender maneuvering and the creation of alternative femininities, it also allowed for alternative masculinities, inviting the participation of men who are “not like the others.

The Christ of John Milton

At a time when western Christendom was reexamining itself and its doctrine, the poet John Milton lived. It is legitimate to assume that this Christian poet would have been concerned with the central figure of the Christian religion, Jesus Christ. This concern is reflected in the works of Milton, not just during a single period but throughout his career. As the central figure of Milton's religion and his thought, the Christ as the Christ of Milton deserves study. As a good Christian, Milton should be credited with having been sincere in whatever he wrote about the Christ, regardless of its orthodoxy in relation to traditional doctrine. The Christ, therefore, should not be viewed as a fictional character in any of Milton's treatment of Him. The problem in a study of what this human-divine figure was to this Christian poet is a real one because of the conflicting concepts and changes within the realm of Hilton's own writings, which may be accepted as evidence of his thought. What Milton actually believed cannot be finally stated by anyone, perhaps not even by the poet himself

The social structure, behavior, and occurrence of bottlenose dolphins in relation to shrimp trawlers in Southport, North Carolina

Bottlenose dolphins use a wide diversity of feeding tactics, and can be quite flexible in their use. Numerous researchers have described associations of dolphins with shrimp trawlers. Trawler foraging is characterized by bottlenose dolphins feeding on organisms stirred up by an actively trawling shrimp boat, bycatch, and/or fish attracted to non-working shrimp trawlers. This study analyzed data collected from boat-based photo-identification surveys conducted from 1998-2003 in the Southport, North Carolina area, where there is an active shrimp fishery in the summer and fall. Based on findings from two recent studies, the following hypotheses were tested: (1) separate, non-interacting communities of trawler and non-trawler dolphins occur, (2) trawler dolphins spend more time socializing and less time feeding than do non-trawler dolphins, (3) trawler dolphins are seasonal in their occurrence and (4) trawler dolphins occur in larger group sizes than non-trawler dolphins. Data from 99 sightings were analyzed (40 trawler sightings and 59 non-trawler sightings). Trawler dolphins were defined as any dolphin seen at least once with a trawler, and non-trawler dolphins were those never seen with a trawler. Of 51 dolphins sighted three or more times in the Southport area, 45 were trawler dolphins and 6 were non-trawler dolphins. Associations between trawler (T) and non-trawler (NT) dolphins were significantly different from those within both NT and T groups (p<0.0001), and within group associations (T-T and NT-NT) were significantly higher than between group associations (NT-T; p<0.0001). T animals had significantly different activity budgets than NT animals (p<0.0001); when not with trawlers, T dolphins spent more time socializing than did NT dolphins. In addition, NT dolphins spent more time traveling than did T dolphins, which could be at least partially due to their increased need to search for food. Sightings of trawler dolphins were highly seasonal, occurring only in the summer and fall (p=0.0033), and larger group sizes (p=0.0020, F=10.07) occurred with trawlers. Non-trawler dolphin sightings occurred primarily in winter in Southport, but year round in other portions of the Wilmington study area. Results support the hypotheses that separate, non-interacting groups of trawler and non-trawler dolphins occur in Southport, NC and that these groups differ in their activity budgets and seasonal patterns of occurrence

How to...mechanically erupt a palatal canine.

Management of ectopic permanent maxillary canines represents one of the greatest challenges to orthodontists. This paper outlines a variety of techniques and mechanics which may facilitate expedient, predictable and safe eruption of palatal canines. While each method may be useful in isolation, the varying presentations of palatal canines ensure that the ability to apply an array of techniques is essential if successful outcomes are to be consistently achieved

Dihydrolipoic acid reduces cytochrome b561 proteins.

Cytochrome b561 (Cyt-b561) proteins constitute a family of trans-membrane proteins that are present in a wide variety of organisms. Two of their characteristic properties are the reducibility by ascorbate (ASC) and the presence of two distinct b-type hemes localized on two opposite sides of the membrane. Here we show that the tonoplast-localized and the putative tumor suppressor Cyt-b561 proteins can be reduced by other reductants than ASC and dithionite. A detailed spectral analysis of the ASC-dependent and dihydrolipoic acid (DHLA)-dependent reduction of these two Cyt-b561 proteins is also presented. Our results are discussed in relation to the known antioxidant capability of DHLA as well as its role in the regeneration of other antioxidant compounds of cells. These results allow us to speculate on new biological functions for the trans-membrane Cyt-b561 proteins

Barrier Coverage Construction without Barrier Breach in Wireless Sensor Networks

In wireless sensor networks, the barrier coverage detects objects crossing a protected area or monitors an area of interest. It is an important application in the wireless sensor networks. In such a wireless sensor network application, sensor nodes are randomly deployed along the boundary of the monitoring area due to cost issues and construct multiple barrier coverage in order to maximize the network life time. These multiple barriers are operated according to the sleep wakeup schedule. In this application, a new security problem which is the barrier breach problem occurs in the sleep wakeup schedule In this work, we propose a new barrier coverage construction algorithm without a barrier breach

General hardware multicasting for fine-grained message-passing architectures

Manycore architectures are increasingly favouring message-passing or partitioned global address spaces (PGAS) over cache coherency for reasons of power efficiency and scalability. However, in the absence of cache coherency, there can be a lack of hardware support for one-to-many communication patterns, which are prevalent in some application domains. To address this, we present new hardware primitives for multicast communication in rack-scale manycore systems. These primitives guarantee delivery to both colocated and distributed destinations, and can capture large unstructured communication patterns precisely. As a result, reliable multicast transfers among any number of software tasks, connected in any topology, can be fully offloaded to hardware. We implement the new primitives in a research platform consisting of 50K RISC-V threads distributed over 48 FPGAs, and demonstrate significant performance benefits on a range of applications expressed using a high-level vertex-centric programming model

Anti-cancer drug validation: the contribution of tissue engineered models

Abstract Drug toxicity frequently goes concealed until clinical trials stage, which is the most challenging, dangerous and expensive stage of drug development. Both the cultures of cancer cells in traditional 2D assays and animal studies have limitations that cannot ever be unraveled by improvements in drug-testing protocols. A new generation of bioengineered tumors is now emerging in response to these limitations, with potential to transform drug screening by providing predictive models of tumors within their tissue context, for studies of drug safety and efficacy. Considering the NCI60, a panel of 60 cancer cell lines representative of 9 different cancer types: leukemia, lung, colorectal, central nervous system (CNS), melanoma, ovarian, renal, prostate and breast, we propose to review current Bstate of art^ on the 9 cancer types specifically addressing the 3D tissue models that have been developed and used in drug discovery processes as an alternative to complement their studyThis article is a result of the project FROnTHERA (NORTE-01-0145-FEDER-000023), supported by Norte Portugal Regional Operational Programme (NORTE 2020), under the PORTUGAL 2020 Partnership Agreement, through the European Regional Development Fund (ERDF).
