在中国北方古文化中,夏家店下层文化属于晚期新石器时代文化及早期青铜时代文化,距今4000-3500年。内蒙古赤峰市元宝山区地处老哈河西岸,境内的元宝山花果山夏家店下层文化遗址和原公格营子乡古山发现的几处夏家店下层文化遗址,都有独特的文化内涵,具备了村落群规模。通过对遗址的发掘资料研究可探知,当时这里人口密集,农业、畜牧业、手工制造业非常发达,揭示了该地区北方夏家店下层文化所反映的社会文明发展进程,说明了老哈河流域也是中华北方文明的发源地。  相似文献

In the nuclear power industry, Level 3 probabilistic risk assessment (PRA) is used to estimate damage to public health and the environment if a severe accident leads to large radiological release. Current Level 3 PRA does not have an explicit inclusion of social factors and, therefore, it is not possible to perform importance ranking of social factors for risk‐informing emergency preparedness, planning, and response (EPPR). This article offers a methodology for adapting the concept of social vulnerability, commonly used in natural hazard research, in the context of a severe nuclear power plant accident. The methodology has four steps: (1) calculating a hazard‐independent social vulnerability index for the local population; (2) developing a location‐specific representation of the maximum radiological hazard estimated from current Level 3 PRA, in a geographic information system (GIS) environment; (3) developing a GIS‐based socio‐technical risk map by combining the social vulnerability index and the location‐specific radiological hazard; and (4) conducting a risk importance measure analysis to rank the criticality of social factors based on their contribution to the socio‐technical risk. The methodology is applied using results from the 2012 Surry Power Station state‐of‐the‐art reactor consequence analysis. A radiological hazard model is generated from MELCOR accident consequence code system, translated into a GIS environment, and combined with the Center for Disease Control social vulnerability index (SVI). This research creates an opportunity to explicitly consider and rank the criticality of location‐specific SVI themes based on their influence on risk, providing input for EPPR.  相似文献

Although there is research on training program evaluation, there is little systematic research on the design, development and use of training reaction evaluations. In order to obtain meaningful information from a program evaluation, evaluation professionals must be rigorous in the design and development of all aspects of an evaluation study, including instrumentation. The purposes of the study were to classify the dimensions of information sought using reaction evaluations and to establish design criteria for developing training reaction instruments. There were three major phases of the study: (1) classification of the dimensions and questionnaire design criteria used in reaction evaluations; (2) validation of the classified dimensions and the questionnaire design criteria by subject matter experts; and (3) assessment of a sample of training reaction instruments currently used in training programs in US corporations. The research findings were: eleven dimensions for reaction evaluation were identified and classified by purpose. Five overall design criteria, each consisting of several sub-criteria, were judged important in the design of reactionnaires. These include: introduction and directions; question format; question construction; questionnaire layout; and data analysis. It was concluded that a well-designed training reaction instrument integrates the proper application of design criteria with appropriate reaction dimensions. Most training reaction instruments used by US corporations consisted of questions representing only a few dimensions. The instruments varied in form and length. Few of them properly utilized the established questionnaire design criteria.  相似文献

该文利用兵团近10年出口贸易数据,构建出口贸易发展水平评价体系并进行了关联分析,结果表明:兵团出口贸易结构不断改善,出口贸易规模以相对平稳的速度不断扩张,出口贸易竞争力不断提升,但出口贸易效益却在不断下降。各指标对出口贸易发展水平的影响依次是出口贸易结构、出口贸易规模、出口贸易竞争力、出口贸易效益和出口贸易速度。总体上,兵团出口贸易发展水平在波动中不断提升。  相似文献

In this paper our main objective is to investigate a deterministic inventory production lot-size model with a permissible delay in payment under a restriction. We analyse our deterministic inventory model under a restriction which will be assumed as the average inventory level. In fact we use in our analysis two approaches: the geometric programming approach; and the Lagrange method. Then a comparison between these two approaches is performed, which is our aim. Finally we deduce some previously published works of other researchers as special cases.  相似文献

The Narrative Policy Framework has a growing number of researchers seeking to apply the framework in policy process scholarship. This article is intended to assist those interested in conducting an NPF study that is ‘clear enough to be wrong’ (Sabatier, 2000). While graduate programs offer critical methodological training, this article focuses on the specific application of the NPF to research inquiries about the role of policy narratives in the policy process. We approach our discussion by examining various decisions in the research process and include a detailed discussion of specifying the model and obtaining narrative data. We also point out areas for further investigation.  相似文献
