Being in the archive: affect and scholarly distance     

Bernadette Brennan 《档案与原稿》2018,46(1):3-17

Working in the archives of living writers provides exciting possibilities for extended interpersonal research as well as ethical challenges. This article explores the author’s experience of working in Helen Garner’s restricted archives and negotiating the demands of scholarly objectivity with an increasingly felt empathic engagement. The author traces a chronological path through the archives relating to Garner’s three substantial works of non-fiction: The First Stone (1995), Joe Cinque’s Consolation (2004) and This House of Grief (2014). She draws attention to some of the ways in which distance and objectivity can be influenced not only by contact with a living writer but also by the space in which the archive is encountered. With a deliberate focus on the lived experience of researching, rather than a scholarly examination of archival theory, the author offers a case study of how the interaction of archives and living subject can shape research and publication.  相似文献   

The effects of short versus long inter-set rest intervals in resistance training on measures of muscle hypertrophy: A systematic review

Although the effects of short versus long inter-set rest intervals in resistance training on measures of muscle hypertrophy have been investigated in several studies, the findings are equivocal and the practical implications remain unclear. In an attempt to provide clarity on the topic, we performed a systematic literature search of PubMed/MEDLINE, Scopus, Web of Science, Cochrane Library, and Physiotherapy Evidence Database (PEDro) electronic databases. Six studies were found to have met the inclusion criteria: (a) an experimental trial published in an English-language peer-reviewed journal; (b) the study compared the use of short (≤60?s) to long (>60?s) inter-set rest intervals in a traditional dynamic resistance exercise using both concentric and eccentric muscle actions, with the only difference in resistance training among groups being the inter-set rest interval duration; (c) at least one method of measuring changes in muscle mass was used in the study; (d) the study lasted for a minimum of four weeks, employed a training frequency of ≥2 resistance training days per week, and (e) used human participants without known chronic disease or injury. Current evidence indicates that both short and long inter-set rest intervals may be useful when training for achieving gains in muscle hypertrophy. Novel findings involving trained participants using measures sensitive to detect changes in muscle hypertrophy suggest a possible advantage for the use of long rest intervals to elicit hypertrophic effects. However, due to the paucity of studies with similar designs, further research is needed to provide a clear differentiation between these two approaches.  相似文献   

Walking and biologic ageing: Evidence based on NHANES telomere data     

Larry A. Tucker 《Journal of sports sciences》2020,38(9):1026-1035

ABSTRACT

The length of telomeres is an objective measure of biologic ageing. This study evaluated the extent minutes of walking per week are associated with leukocyte telomere length (LTL) in a random sample of 5,823 U.S. adults. The investigation was cross-sectional and data were obtained from the National Health and Nutrition Examination Survey (NHANES). LTL was measured by the quantitative polymerase chain reaction method. Walking minutes was calculated from walking frequency and duration measures. Results showed that for each year of chronological age, telomeres were 15.6 base pairs shorter (P < 0.0001). With walking minutes and LTL treated as continuous variables, the relationship was quadratic, not linear (F = 11.2, P = 0.0023). With walking time divided into three categories, adults who performed ≥ 150 minutes of walking per week had longer telomeres than those who did no regular walking, and those who did some, but less than the recommendation (F = 5.0, P = 0.0137). Regular walkers were estimated to have a biologic ageing advantage associated with 6.5–7.6 years less biologic ageing compared to non-walkers, after adjusting for covariates. Additional investigations designed to study causality and the mechanisms associated with the walking and LTL relationship are needed.  相似文献

HIV感染者与体育运动     

赵宝椿  李田 《赣南师范学院学报》2006,27(3):100-103

目的:探讨体育运动对艾滋病毒感染者免疫功能的影响,以及艾滋病毒感染者运动比赛时的传染性和预防措施.结果:适度的体育运动可以提高艾滋病毒感染者的免疫功能,并作为辅助治疗手段在艾滋病毒感染者的综合治疗中起着重要作用.至今还未发现因从事体育运动及比赛而感染艾滋病的病例,但在运动中当血液明显暴露在开放性创口时,艾滋病毒的传播是可能的.预防的措施应注重对出血的及时发现和处理,并加强对运动员的教育和特殊管理.  相似文献

主观幸福感内容成分的结构关系     

何立国  黄蕾 《宁波大学学报(教育科学版)》2011,33(3):27-31

抽取了有代表性的506名中学生和大学生,通过结构方程建模方法对青少年学生主观幸福感的成分结构作实证的检验与分析,结果表明：正性情感和负性情感是SWB的两个相对独立的成分,在认知成分（生活满意度）与正性情感和负性情感的因果关系没得到证明之前,SWB的指标值应该是三者的综合。  相似文献
