黑僵菌var.majus原生质体的再生回复

研究了黑僵菌ｖａｒ．ｍａｊｕｓ原生质体的性状和再生回复。黑僵菌ｖａｒ．ｍａｊｕｓ原生质体的无核率为２５．３％,有核率为７４．７％,其中单核率为５３．６％,原生质体再生回复的形态可观察到三种,从再生频率和菌落生长发育速度这两方面综合考虑,选择以０．７ｍｏｌ／Ｌ葡萄糖作为原生质体再生回复用培养基的渗透压稳定剂较为合适。

Associations of total sedentary time,screen time and non-screen sedentary time with adiposity and physical fitness in youth: the mediating effect of physical activity

The aims of the present study were: i) to examine the associations of total accelerometer-based sedentary time (ST) and specific-domain self-reported ST (i.e., screen-based, educational-based, social-based, and other-based ST) with adiposity and physical fitness in youth; and ii) to analyse the mediation effect of physical activity (PA) on associations.

This study was conducted with 415 children (9.1 ± 0.4 years) and 853 adolescents (13.6 ± 1.6 years) in Spain during 2011–2012. Total ST and PA were assessed by accelerometry. Leisure-time spent in twelve sedentary behaviours was self-reported. Adiposity and physical fitness was measured following the ALPHA battery for youth.

Total accelerometer-based ST was positively associated with global adiposity score in children, and negatively associated with global physical fitness score in children and adolescents; but relationships were not independent of PA. PA mediated all associations of accelerometer-based and self-reported ST with adiposity or physical fitness in children. Conversely, screen-, educational-, social-, and other-based ST were negatively related to physical fitness in adolescents, independently of PA.

These findings give an impetus to developing effective strategies for specifically promoting PA in children and for increasing PA while reducing ST in adolescents in order to produce improvements on adiposity and physical fitness.     

从体育价值方面谈学校体育与健康的关系

首先对体育价值进行了界定和分类，以此来揭示体育价值的内涵，进而从体育价值角度考察了体育与健康关系、学校体育的本质，认为体育在学生的心理建设和个体社会方面的价值也是学校体育本质的价值属性。     

大学课程决策权力的层级分布及其后果——以X大学的课程决策为例

大学课程决策权力的分布状态造就了不同份量的决策主体,也在一定程度上决定了课程决策的过程与结果。X大学的课程决策权力呈现出从核心层列参与层再到影响层的渐次递减的层级分布,课程决策主体总是操纵大学课程的"少数人"。横向上,决策权力偏向行政权力,学术权力、学生权力不足;纵向上,决策权力集中在上层,普通教师和管理人员权力缺乏。因此,应该均衡大学内部的权力配置,坚持课程决策的民主化、科学化和制度化价值取向,加强课程决策评价的研究和应用。     

ACED IT: A tool for improved ethical and moral decision-making

Numerous examples of unethical organizational decision-making highlighted in the media have led many to question the general moral perception and ethical judgments of individuals. The present study examined two forms of a straightforward ethical decision-making (EDM) tool (ACED IT cognitive map) that could be a relatively simple instrument for organizations to improve the moral and EDM of its members. Results revealed that participants utilizing either form of ACED IT were more likely to identify a moral dilemma than were control participants. Additionally, participants in the modified condition responded differently to the situation. Implications and other findings are discussed.     

档案馆话语建构初探

目前档案馆扮演的社会角色日趋多样化,需要通过话语的建构加以体现.档案馆话语的构成要素包括话语平台、话语对象、话语内容和话语权.在建构话语的过程中,档案馆必须加强自身话语权意识,真正实现档案馆工作由"档本位"向"人本位"的转变,并积极建构能体现自身价值的话语内容资源.
