Green jobs for the disadvantaged in British Columbia: the perspectives of non-governmental organisations and social entrepreneurs

This paper examines the actions and potential of green jobs for the disadvantaged, from the perspective of non-governmental organisations and social entrepreneurs. The populations of interest include: low-income, developmentally challenged, those with mental health or addiction issues, women, and First Nations. Findings indicate that green businesses and social entrepreneurs have uniquely engaged in social training and hiring strategies related to green jobs. The major challenges they face include a lack of policies that support the development of green jobs through social training and hiring. As a result of these findings, an argument is made for combining job and life skills for both disadvantaged populations and the agencies that serve them as well as building the capacity of employers to practise social hiring.

油库雷击事故的预防与控制

油库是储存易燃易爆油品的专用场所,雷电是油库安全生产的重大隐患,油库防雷已成为关系到经济建设、社会发展和人民生命财产安全的重大课题。针对目前我国油库雷击事故频繁发生的问题,在对大量事故资料研究的基础上,分析了油库雷击火灾爆炸事故的原因,指出雷电产生的火花引燃油气是导致油库火灾爆炸的主要原因。并重点从安全管理学的角度,运用事故预防与控制的＂3E＂对策,分别从安全技术、安全管理、安全教育三个方面探讨了油库雷击事故的预防与控制措施。     

铁路交通安全培训“六要素”探讨

结合铁路交通安全的严峻形势,对铁路交通安全培训的＂5W1H＂六要素进行了初步的分析。＂5W1H＂包括原因（WHY）、内容（WHAT）、地点（WHERE）、时间（WHEN）、人员（WHO）、方法（HOW）这六个方面,本文对铁路交通安全培训的政策背景（即原因）、内容、地点、时间、人员和实施方法进行分析,回答这六个方面的问题,寻求合理可行的解决措施,并以此形成有效的铁路交通安全培训模式。     

城市道路环境中驾驶人应激反应能力研究

为预防驾驶人在城市道路行车时因应激反应失误而引发交通事故,基于动力定型理论,开发驾驶人应激反应训练系统并进行仿真试验研究。试验选用30名被试人员分别在3个城市道路中典型应激交通场景下进行,运用MP150实时记录被试人员的心率参数,运用对数回归和相关性分析,研究应激反应能力与训练次数间的定量关系。研究结果表明,随着训练次数增加,驾驶人应激反应能力增强。驾驶人经过标准规定次数的训练,即可减缓应激状态下的心理紧张,提高应激反应准确性和速度。设计的系统及建立的训练次数标准,满足驾驶人应激反应能力训练需求,可增强驾驶人应激能力,减少此类交通事故发生。     

植物激素对平菇茵丝生长及酶活性的影响

采用固体平板和液体摇瓶培养方法,研究了赤霉素、2,4-D、吲哚乙酸和萘乙酸4种激素对平菇- 126菌丝生长及酶活性的影响.结果表明,吲哚乙酸虽然能提高发酵液胞外蛋白的含量和过氧化物酶活性,但对菌丝的生长起抑制作用,这与吲哚乙酸能引起平菇菌丝裂解和细胞膜渗漏有关;萘乙酸、低浓度2,4-D能促进菌丝的伸长;萘乙酸、赤霉素在低浓度下也能促进菌丝的分枝,对菌丝的生长整体上起促进作用.除吲哚乙酸外,其他3种激素对平菇菌丝生长影响都有两重性:低浓度下能促进菌丝的生长,浓度过高则会对菌丝生长产生毒害作用.     

Occupational Health Care in Small and Medium-Sized Enterprises—How Many Doctors Do We Need and How Do We Ensure Good Care?

The translation of the framework directive 89/391/EEC (Council Directive 89/391/EEC) into national law aims at supplying occupational protection and health care to all employees of large, small, and medium-sized enterprises (SMEs) likewise, depending on assessed exposure. Prior incomplete protection of the German workforce with bias against the SMEs requires an assessment of quantitative and qualitative adequacy of present occupational health care practice and also of future needs.

Therefore, the Federal Institute for Occupational Safety and Health of Germany initiated a study to evaluate the present state of occupational health care in 4 regions with different geographic and economic structure. Based on these data the future demand for adequately trained occupational physicians will be estimated by employing a statistical method that allows for including a large number of modifying variables (economic development, demographic change, etc.).

Expected result of the applied technique are the estimated minimal and maximal number of occupational physicians that have to be trained to meet future demand. In the same study models of best practice will be identified and evaluated for general application. The project started in October 1997 and will be finished by January 2000.     

Development of PAOT Tool Kit for Work Improvements in Clinical Nursing

The aim of this study was to develop an action checklist for educational training of clinical nurses. The study used qualitative and quantitative methods. Questionnaire items were extracted through in-depth interviews and a questionnaire survey. PASW version 19 and AMOS version 19 were used for data analyses. Reliability and validity were tested with both exploratory and confirmative factor analysis. The levels of the indicators related to goodness-of-fit were acceptable. Thus, a model kit of work improvements in clinical nursing was developed. It comprises 5 domains (16 action points): health promotion (5 action points), work management (3 action points), ergonomic work methods (3 action points), managerial policies and mutual support among staff members (3 action points), and welfare in the work area (2 action points).
