The relationship between work conditions and perceptions of organizational justice among library employees     

Miriam L. Matteson  Yue Ming  David E. Silva 《Library & information science research》2021,43(2):101093

Library employees hold perceptions about the fairness of the outcomes, processes, and interpersonal treatment in their workplaces. When employees feel the workplace is fair they are more likely to feel commitment to the organization, perform in-role and extra-role tasks, and experience job satisfaction. When employees perceive injustice in the workplace, research points to negative outcomes such as withholding work or even sabotage. To understand the antecedents of organizational justice, researchers carried out a national survey of librarians to compare the predictive power of perceived organizational support, job autonomy, job feedback, and job stress. Results indicate that increasing librarians' perceptions of organizational support and their autonomy, and providing meaningful and timely job feedback can increase overall perceptions of justice. Managers can enhance a climate of justice in their workplaces by developing strategies that target organization support, autonomy, and feedback to reduce a sense of injustice between and among employees.  相似文献   

前列腺癌:亟待肿瘤标志物和治疗新靶点(英文)     

Juliana FELGUEIRAS  Joana Vieira SILVA  Margarida FARDILHA 《Journal of Zhejiang University. Science. B》2014,(1)

研究目的:这篇综述系统地阐述了前列腺癌的发生、发展、相关分子信号通路以及分子标志物用于前列腺癌的临床诊断和前列腺癌诊治所面临的挑战。重要结论:许多分子信号通路通过影响细胞生长、凋亡、血管生成等病理生理过程而参与了前列腺癌的起始、发生和发展。这些研究基础有助于寻找前列腺癌的肿瘤标志物和改进前列腺癌的治疗。虽然去势治疗是早期前列腺癌治疗的金标准,但是晚期的激素抵抗型前列腺癌(CRPC)的治疗仍面临着巨大的挑战。所幸的是,目前研究发现可以通过切断特异的蛋白-蛋白相互作用或者通过调节某些影响肿瘤生长和转移的关键分子来治疗前列腺癌,能减少传统治疗所带来的副作用;相关临床研究已开始实施。这些研究进展给前列腺癌的诊治带来了新的曙光。  相似文献   

Promoting Inquiry-Based Teaching in Laboratory Courses: Are We Meeting the Grade?     

Christopher Beck  Amy Butler  Karen Burke da Silva 《CBE life sciences education》2014,13(3):444-452

Over the past decade, repeated calls have been made to incorporate more active teaching and learning in undergraduate biology courses. The emphasis on inquiry-based teaching is especially important in laboratory courses, as these are the courses in which students are applying the process of science. To determine the current state of research on inquiry-based teaching in undergraduate biology laboratory courses, we reviewed the recent published literature on inquiry-based exercises. The majority of studies in our data set were in the subdisciplines of biochemistry, cell biology, developmental biology, genetics, and molecular biology. In addition, most exercises were guided inquiry, rather than open ended or research based. Almost 75% of the studies included assessment data, with two-thirds of these studies including multiple types of assessment data. However, few exercises were assessed in multiple courses or at multiple institutions. Furthermore, assessments were rarely based on published instruments. Although the results of the studies in our data set show a positive effect of inquiry-based teaching in biology laboratory courses on student learning gains, research that uses the same instrument across a range of courses and institutions is needed to determine whether these results can be generalized.  相似文献

Literacy for All: a Consideration of the Many Opportunities for Language Acquisition     

Carole Silva 《Literacy》1997,31(2):36-37

There are lots of opportunities in a classroom day for the development of literacy. Reading aloud to children is one of the most important of these. Carole Silva here reminds us of the potential of this activity and gives several practical suggestions for working with children.  相似文献   

Distinction through visual art     

Dr Elizabeth B. Silva 《Cultural Trends》2006,15(2-3):141-158

Visual art is one of the fields where, according to Bourdieu, culture is used to reproduce the class structure. Like other items in the cultural repertoire, paintings, as major examples of visual art, imply social divisions in how they are engaged with by artists, critics and audiences. Within the Bourdieusian framework, cultural engagements with paintings are interpreted as indicators of social position, since appreciation depends on a trained capacity in the family and the educational system, which is often inaccessible to less powerful sections of the population. This would imply that the sorts of paintings favoured by working-class people differ from those preferred by the middle or upper classes. More recent studies have contested the view that a gulf exists between the art tastes of different classes in ways that reproduce the class structure. The argument of the omnivore thesis that distinctions between more popular and legitimate tastes have become blurred has predominantly been based on empirical references in the field of music. This article explores this thesis on the basis of data about visual arts in the Cultural Capital and Social Exclusion project. While some differences continue to be connected to social divisions of income, education and occupational groups, important similarities are found across the board, and certain significant differences appear to relate to factors other than social class, such as ethnicity, age and gender. It is also significant that some people appear disconnected from and disinterested in paintings.  相似文献

Anthropometric profiles of elite older triathletes in the Ironman Brazil compared with those of young Portuguese triathletes and older Brazilians     

Silva DA  Benedetti TR  Ferrari EP  Meurer ST  Antes DL  Silva AM  Santos DA  Matias CN  Sardinha LB  Vieira F  Petroski EL 《Journal of sports sciences》2012,30(5):479-484

The objective of this study was to describe the anthropometric profiles of elite older triathletes participating in the 2009 Ironman Brazil and to compare their somatotype, anthropometric and body composition characteristics with those of elite young triathletes and older non-athletes. The sample consisted of 64 males, divided into three groups: (1) older triathletes (n = 17), (2) young triathletes (n = 24), and (3) older non-athletes (n = 23). Somatotype was analysed according to the Carter and Heath ( 1990 ) method. Body mass index, sum of four skinfolds, percentage body fat, body fat mass, and fat-free mass were also estimated. Older non-athletes had higher endomorphy, sum of four skinfolds, fat percentage, and body fat mass than the athletes. Older athletes who participated in the Ironman and elite young triathletes had higher fat-free mass than older non-athletes. Older triathletes and older non-athletes were considered mainly endomorphic mesomorphs and young triathletes mainly ectomorphic mesomorphs. The findings that characterize the anthropometric profile of athletes in this sports modality could be used as a reference.  相似文献   

Creatine kinase activity weakly correlates to volume completed following upper body resistance exercise     

Machado M  Willardson JM  Silva DR  Frigulha IC  Koch AJ  Souza SC 《Research quarterly for exercise and sport》2012,83(2):276-281

In the current study, we examined the relationship between serum creatine kinase (CK) activity following upper body resistance exercise with a 1- or 3-min rest between sets. Twenty men performed two sessions, each consisting of four sets with a 10-repetition maximum load. The results demonstrated significantly greater volume for the 3-min condition (M = 4156 kg, SD = 867, for 3 min; vs. M = 3503 kg SD = 759, for 1 min; p < .001), with no significant differences in delta CK activity between conditions (p = .574). Nevertheless, there was a weak correlation between the delta CK activity and total volume of exercise completed (r = .55 with a 1-min rest, and r = .45 with a 3-min rest). Therefore, the volume following upper body resistance exercise correlates weakly with serum CK levels, irrespective of rest interval length between sets.  相似文献   

论美国会计准则的国际协调     

乌达 《赤峰学院学报(自然科学版)》2010,26(4):51-54

会计准则国际趋同已成为大势所趋,美国在此过程中更加注重国际会计准则的高质量,即满足可比性、透明度、充分性等重要特征．这就表明美国在迫于各方压力不得不开展会计准则国际趋同工作的同时,也不愿放弃原本已较为完善的公认会计原则,并试图以高质量作为条件使IFRS与美国GAAP趋同．在此背景下,加强中美会计对话,促使美国认同中国的会计准则,无疑具有重要的现实和长远意义．  相似文献
