A growing knowledge regarding the influence of exercise on adverse physiologic outcomes associated with cancer and its treatment exists. Aside from its effects on psychological behavior, quality of life, and cancer-related fatigue, physical exercise can target physical and cardio-respiratory fitness, insulin regulation and metabolic syndrome, body weight and composition, and immune function in tumor patients. The increasing number of study results for different cancer types, which prove the positive influences of physical activity in cancer patients, changed the contradictory opinions which existed until the end of the last century. Although an increasing number of studies showing the positive effects of physical activity and more specifically of endurance and resistance training in cancer patients have been published, the underlying mechanisms are mostly unknown. Thus, we summarized the current knowledge of the effects of physical activity and specific training in different tumor entities with specific respect to the possible underlying mechanisms. Especially, the association between physical activity and (1) the improvement of fatigue and the role of free radicals in this process, (2) the counterbalance of tumor-induced cachexia, (3) the improvement of the immune system for supportive tumor treatment, and (4) the possible role of epigenetic modulation against tumor and tumor treatment-dependent adverse physiologic outcomes is focused. 相似文献

Negative psychological and physical effects of prostate cancer and its medical treatment may persist many years after diagnosis. The influence of a long cycling tour on rehabilitative or health-related effects with prostate cancer patients has not yet been studied. In practice, physicians and therapists rarely recommend cycling to prostate cancer. In May 2010, eight prostate cancer patients rode their bikes for over 1,408 km from Cologne to Marseille within 5 weeks. Endurance test, blood examinations (prostate-specific antigen (PSA), total testosterone, interleukin-6, oxidative stress, and antioxidant capacity) and quality of life questionnaires were completed before and after the tour. All eight subjects reached Marseille. Significant improvements could be observed in physical performance and certain quality of life scores (p?=?0.008), as well as a reduction of total testosterone (p?=?0.19). PSA levels did not change. This pilot study suggests that long bicycle tours with prostate cancer patients are feasible. Due to the missing control group and the small sample size, the results of this pilot study are limited. 相似文献

This study empirically examines the impact of two human resource management (HRM) systems on operational performance in two distinct mass customisation manufacturing (MCM) environments. Using the survey data collected electronically from 148 mass customisation manufacturers in the USA, moderated hierarchical multiple regression was employed to test the research hypotheses. Results suggest that operational performance significantly increases when a bundle of complementary basic HRM practices are integrated in MCM contexts that emphasise module and process standardisation. This finding indicates that these types of mass customisation manufacturers are capitalising on the opportunity to improve operational performance by strategically combining several different, but supportive, traditional HRM practices with a finite MCM system. 相似文献

Most of us have encountered problems in developing an effective quantitative analysis program for our business schools in the United States. We have often found managers very reluctant to adopt QA techniques; on the other hand, students, although not reluctant, lacked the necessary mathematical background. During the academic year 1970–71, the authors assisted in the development of a QA department in the business school of a developing nation which offers both resident coursework for graduate students and executives seminars for businessmen. Both the students and the executives had the necessary mathematical background for rapid understanding of QA techniques. The executives appeared eager to use QA in their business operations and the students were highly motivated toward the application of QA to business problems. Our purpose in this article is not to convince all the QA professors to teach in underdeveloped nations, but to furnish information which is likely to be useful to those who attempt to establish similar QA programs in other developing countries. 相似文献

Research literature indicates the importance of workforce development in the successful implementation of advanced manufacturing technologies (AMTs). However, the relationship between advanced technologies and workforce training is assumed to be a direct one with limited consideration provided to factors that may influence it. This study examines the impacts of environment and human resource (HR) manager perceptions on the provision of workforce development activities. A human-centered technology philosophy is proposed as a conceptual framework for examining the role of HR manager perceptions to mediate the relationship between AMTs and workforce development. Results from hierarchical regressions indicate that the perceptions of HR managers regarding technology-driven workforce need to explain a large portion of the variance for both individual and process development activities. Findings support that the managerial role of assessing workforce developmental needs from basic AMTs places HR managerial perceptions at the focal point of social–technical systems. The role of environmental uncertainty is also examined as a moderator of managerial perceptions of technology-driven needs in an AMT environment. The results suggest that environmental uncertainty did not moderate the relationship between HR perceptions as a predictor of workforce development activities. This could imply that HR managers may not consider critical external environment issues when making decisions of workforce development activities. The implications of these findings for HR perceptions in an AMT environment are discussed, and suggestions for future research are provided. 相似文献

ABSTRACTHealth outcomes are affected by patient, provider, and environmental factors. Previous studies have evaluated patient-level factors; few focusing on environment. Safe clinical spaces are important for lesbian, gay, bisexual, and transgender (LGBT) communities. This study evaluates current models of LGBT health care delivery, identifies strengths and weaknesses, and makes recommendations for LGBT spaces. Models are divided into LGBT-specific and LGBT-embedded care delivery. Advantages to both models exist, and they provide LGBT patients different options of healthcare. Yet certain commonalities must be met: a clean and confidential system. Once met, LGBT-competent environments and providers can advocate for appropriate care for LGBT communities, creating environments where they would want to seek care. 相似文献

Pathological gambling has been characterised by DSM-III-R and DSM-IV as a disorder of impulse control with a proportion of gamblers identified as meeting criteria for a co-morbid diagnosis of Antisocial Personality Disorder. To date, empirical evidence in support of the notion that pathological gamblers as a group manifest elevated traits of impulsivity remains equivocal. Principal components analysis was used to investigate relationships between the constructs of impulsivity, psychopathy, DSM-III-R criteria for Antisocial Personality Disorder, psychological distress, criminal offending behavior and a range of other common psychological measures employed with pathological gamblers. The sample comprised 115 pathological gamblers, 80 consecutive gamblers seeking treatment from a general hospital psychiatric inpatient behavior therapy unit, and 35 volunteer Gamblers Anonymous attenders. Four primary factors were determined: psychological distress, sensation seeking, crime and liveliness, and impulsive-antisocial. Results suggest that pathological gambling consists of a number of discrete and reproducible factorial structures. The impulsive antisocial factor was found to be associated with gambling behavior and indices of poor psychosocial functioning. 相似文献
