为保障大学生在开放实训室独立开展创新实践活动中的安全,本文从"人防、物防、技防"3个范畴提出实训室开放的具体安全防护策略。其中,人防策略提出了以学生为主体的基于理论结合实操模式的实训室准入制度、教师为主导的指导和监管制度;物防侧重从实训室开放的制度保障、实训室文化、设备安全改造3方面给出防护策略;技防则将"互联网+"、"APP+"的现代技术融入在人防和物防策略中,使得三防相辅相成,进而为实训室开放与共享提供更为全面可行的防护策略,避免安全事故的发生。 相似文献

The safety climate of an organization is considered a leading indicator of potential risk for railway organizations. This study adopts the perceptual measurement–individual attribute approach to investigate the safety climate of a railway organization. The railway safety climate attributes are evaluated from the perspective of railway system staff. We identify four safety climate dimensions from exploratory factor analysis, namely safety communication, safety training, safety management and subjectively evaluated safety performance. Analytical results indicate that the safety climate differs at vertical and horizontal organizational levels. This study contributes to the literature by providing empirical evidence of the multilevel safety climate in a railway organization, presents possible causes of the differences under various cultural contexts and differentiates between safety climate scales for diverse workgroups within the railway organization. This information can be used to improve the safety sustainability of railway organizations and to conduct safety supervisions for the government. 相似文献

建筑施工中的环境污染治理问题日益得到重视.绿色施工是可持续发展战略在建筑业中应用的主要体现,是国家可持续战略的重要组成部分,也是建筑业的发展趋势.为应用"绿色施工"来控制和减少建筑施工中的环境污染,应将建筑施工中的环境污染进行分析并落实绿色施工组织管理等策略.只有准确而详细地进行环境污染分析,才能提出有针对性的、容易取得实效的绿色施工环保措施.只有有效地组织管理,通过建立组织结构,明确各建筑参与方责权关系等,才能有效实现绿色施工的预定目标. 相似文献

Objectives: In this study, we aimed to determine whether three minimum legal drinking age 21 (MLDA-21) laws—dram shop liability, responsible beverage service (RBS) training, and state control of alcohol sales—have had an impact on underage drinking and driving fatal crashes using annual state-level data, and compared states with strong laws to those with weak laws to examine their effect on beer consumption and fatal crash ratios.Methods: Using the Fatality Analysis Reporting System, we calculated the ratio of drinking to nondrinking drivers under age 21 involved in fatal crashes as our key outcome measure. We used structural equation modeling to evaluate the three MLDA-21 laws. We controlled for covariates known to impact fatal crashes including: 17 additional MLDA-21 laws; administrative license revocation; blood alcohol concentration limits of.08 and.10 for driving; seat belt laws; sobriety checkpoint frequency; unemployment rates; and vehicle miles traveled. Outcome variables, in addition to the fatal crash ratios of drinking to nondrinking drivers under age 21 included state per capita beer consumption.Results: Dram shop liability laws were associated with a 2.4% total effect decrease (direct effects: β =.019, p =.018). Similarly, RBS training laws were associated with a 3.6% total effect decrease (direct effect: β =.048, p =.001) in the ratio of drinking to nondrinking drivers under age 21 involved in fatal crashes. There was a significant relationship between dram shop liability law strength and per capita beer consumption, F (4, 1528) = 24.32, p <.001, partial η2 =.016, showing states with strong dram shop liability laws (Mean (M) = 1.276) averaging significantly lower per capita beer consumption than states with weak laws (M = 1.340).Conclusions: Dram shop liability laws and RBS laws were both associated with significantly reduced per capita beer consumption and fatal crash ratios. In practical terms, this means that dram shop liability laws are currently associated with saving an estimated 64 lives in the 45 jurisdictions that currently have the law. If the remaining 6 states adopted the dram shop law, an additional 9 lives could potentially be saved annually. Similarly, RBS training laws are associated with saving an estimated 83 lives in the 37 jurisdictions that currently have the laws. If the remaining 14 states adopted these RBS training laws, we estimate that an additional 28 lives could potentially be saved. 相似文献

Immigrant bacteria located on leaf surfaces are important to the health of plants as well as to people who consume fresh fruits and vegetables. However, the spatial distribution and organization of these immigrant bacteria on leaf surfaces are still poorly understood. To examine the spatial organization of these strains, two bacterial strains on tobacco leaves: (1) an indigenous strain, Pseudomonas stutzeri Nov. Y2011 labeled with green fluorescent protein, and (2) an immigrant strain Pantoea agglomerans labeled with cyan fluorescent protein isolated from pear, were studied. Under moist conditions, P. agglomerans cells quickly disappeared from direct observation by laser- scanning confocal microscopy, although elution results indicated that large amounts of live cells were still present on the leaves. Following exposure to desiccation stress, particles of cyan fluorescent protein-labeled P. agglomerans were visible within cracked aggregates of P. stutzeri Nov. Y2011. Detailed observation of sectioned aggregates showed that colonies of immigrant P. agglomerans were embedded within aggregates of P. stutzeri Nov. Y2011. Furthermore, carbon-resource partitioning studies suggested that these two species could coexist without significant nutritional competition. This is the first observation of an immigrant bacterium embedding within aggregates of indigenous bacteria on leaves to evade harsh conditions in the phyllosphere. 相似文献

Soil and water conservation (SWC) contests among farmer groups were organized in five rural villages in the Bolivian mountain
valleys. The contests were aimed at quickly achieving widespread sustainable results. This article analyzes the effectiveness
of these contests as an extension tool. Mixed results were obtained. In three villages, participation rates in the SWC activities
introduced in the contests were still high even 2 years after project withdrawal. These were all villages where a solid foundation
for sustainable development had been laid before the contests were held. Two years later, most families were still involved
in maintenance of the SWC practices introduced in the contests, and many farmers had started to experiment with different
soil management practices. However, replications of these SWC practices were not widespread, Conservation Leaders did not
continue with their training activities, and the quality of maintenance of the practices was often not satisfactory. In order
to become a more effective extension tool and achieve widespread impact, SWC contests must receive continued support by a
catalyst agency. Moreover, other SWC contests should also be organized in which practices are not predefined. Given that SWC
contests are a low-budget extension tool, local municipalities could become more actively involved. 相似文献

ABSTRACT .This paper attempts to spell out the difficult conditions faced by urban water supply managers in achieving overall efficiency. Based upon these conditions, and changes that are likely in the next decade, it then tries to suggest strategies that would lead to even higher levels of efficiency in the future. A blending of political and economic concepts is used to make what is hoped to be a realistic analysis. What do we mean by “efficient”? The usual welfare economics definition is attainable only under a very special and highly unrealistic set of institutional arrangements. As soon as we delegate responsibility to a specialized agency we provide the opportunity, indeed we make it imperative that, in a social sense, a sub-optimization will take place. From the specifics of the indictment of this sub-optimization we can learn something about the opportunities for more efficient management in the future. In general there is an under-exploitation of multiple-function, multiple-objective opportunities. The pressures for sub-optimization hinge very directly on the sources of support and opposition to the water supply agency. A change requires the creation of a broader political base. The search for regional solutions is largely a political problem, and probably the development of flexible, responsive regional agency, so long sought, is still the answer. 相似文献
