基于文化部、财政部在全国提出的"三馆"免费开放的背景,对公共图书馆与农民工的"补偿教育"问题进行了重新认识:一方面,服务于农民工既是公共图书馆自身的历史使命,又是公共图书馆的社会责任;另一方面,农民工的"补偿教育"也离不开公共图书馆。在此基础上又分析了在新时期公共图书馆为农民工的"补偿教育"更好服务的途径。 相似文献

Forestry occupations are known to be physically demanding, and workers are often paid on a piece rate basis. This pay system is largely used in silvicultural treatments such as plantation and vegetation management. An ill adjusted piece rate system may induce workforce recruitment difficulties or increase accident rates and work related illnesses. A study combining work measurement, ergonomics and economics was undertaken to better understand the factors influencing a worker's workload. Mathematical relations between site factors, worker's production and heart rate variation during work have been examined based on time and motion studies of 38 brushsaw operators performing regeneration release (cleaning) in northern forests. Results show that a piece rate pay system that considers only the area treated without taking into account site factors may lead workers to behave in ways that may compromise their health and safety. The use of a pay system that integrates the influence of site factors on work performance is therefore suggested. 相似文献

以SLA分析框架为理论基础,以东北国有林区职工家庭为研究单位,运用实地问卷调查数据,对东北国有林区职工家庭生计能力脆弱性进行分析。结果表明,社会资本越来越成为影响职工家庭生计脆弱性的重要因素,理顺职工家庭的社会关系是职工家庭社会资本再造的重要途径。 相似文献

在金融危机的冲击下,我国大量农民工失业返乡。在引导和促进农民工自我发展,使其成为市场经济中有竞争力的主体方面,公共图书馆应有所作为。对农民工进行培训,让农民工有一技之长,进一步提高农民工素质,无论是对于农民工自主创业还是再就业都起着至关重要的作用。 相似文献

本文采用双向凝胶电泳法对小峰熊蜂工蜂蛹期的3个发育期进行蛋白质组研究,结果表明小峰熊蜂工蜂蛹期的白眼期（A期）、褐眼期（B期）和黑眼期（C期）分别检测到77、81和59个蛋白点,特有蛋白分别为7个、6个和1个,共有蛋白为48个,A期到B期显著上调的蛋白有9个,显著下调的蛋白有3个,B期到C期显著上调的蛋白有8个,显著下调的蛋白有3个,A期到C期显著上调的蛋白有15个,显著下调的蛋白有2个。研究还发现有17个蛋白是在A期和B期表达而在C期关闭;有2个蛋白是在A期表达,B期关闭,在C期又表达。本研究初步揭示了小峰熊蜂工蜂从蛹期发育到成蜂过程中,不仅需要一些保守蛋白来调控,而目．还需要一此特异蛋白。 相似文献

应用微卫星DNA技术研究中华蜜蜂群内工蜂监督效果 总被引：8，自引：3，他引：5
【目的】研究不同中华蜜蜂（Apis cerana cerana）群内的工蜂繁殖现象,探讨蜂群的工蜂监督效果。【方法】以中华蜜蜂为试验材料,对处女蜂王分别进行单雄和双雄人工授精,并以蜂王自然交尾的蜂群作为对照。蜂王成功繁殖后7周,利用蜜蜂微卫星DNA技术检测蜂群内的雄蜂是由蜂王产的未受精卵发育而成,还是由工蜂产的未受精卵发育而成。【结果】所有蜂群中的雄蜂都是由蜂王产的未受精卵发育而成。【结论】在人工授精和自然交尾蜂群中都明显存在工蜂监督行为。 相似文献

From the mere presence of plants to window views of nearby nature, contact with nature in the workplace has been associated with increased productivity and creativity, as well as positive emotional and physical health outcomes. Nevertheless, if nature is to be incorporated within or near workplaces effectively, it is important that workers perceive natural spaces to be conducive, and not detrimental, to performance on activities that they may engage in at work or else these changes to the physical environment may not be fully embraced by workers. Thus, in the current research we examine workers’ preferences and perceptions of different natural and constructed (built) environments for different workplace activities. In Study 1, 64 knowledge workers were exposed to images of natural outdoor and constructed indoor workspaces. They selected where they thought they would best and least be able to perform different workplace activities. Natural outdoor spaces were overrepresented as the best spaces for around 75% of the workplace activities, and were underrepresented as the worst spaces across all workplace activities. In Study 2 (N = 33), wherein participants evaluated various spatial qualities of the natural outdoor and constructed indoor space types that were included in Study 1, the natural outdoor spaces were rated as more fascinating, relaxing, open, bright, and quiet. The results of this research project suggest that natural outdoor workspaces are viewed as highly flexible, multi-use spaces that are appropriate for diverse workplace activities. Furthermore, access to diverse workspace types with different spatial qualities appears to be highly valued. 相似文献

茶业经济成为近代祁门的支柱产业,茶工在茶叶生产制作中发挥重要作用。按照茶叶制作工序,可将茶工分为有摘茶工和制茶工两类。茶工群体的文化素质普遍较低,劳动强度大,工资待遇低,但其内部也因性别与工种的不同而存在一定的差异。茶工群体身份较为复杂,对近代祁门地方秩序造成了一定的负面影响。 相似文献
