In this article, we present a test for testing uniformity. Based on the test, we provide a test for testing exponentiality. Empirical critical values for both the tests are computed. Both the tests are compared with the tests proposed by Noughabi and Arghami [H. Alizadeh Noughabi, and N.R. Arghami, Testing exponentiality using transformed data, J. Statist. Comput. Simul. 81 (4) (2011), pp. 511–516] using simulation experiments for a wide class of alternatives. The tests possess attractive power properties.  相似文献

雍正初年,清世宗在钱塘江海塘修筑中提出了“一劳永逸”的目标,并且为实现治水目的,在意识形态层面将海塘工程纳人到了“天人感应”理念的范畴。但是,“天神赐佑”、“非人力所能”与“一劳永逸”目标之间存在着明显的逻辑矛盾,从而对塘工修筑产生了深刻影响。意识形态与水利工程的交融,因此成为雍正朝治水政治的一大特点。  相似文献

莎士比亚《一报还一报》一剧以克劳狄奥与朱丽叶的婚前私通为主要伦理线,展示了维也纳法治下个人私通和公共淫乱两类人的跌宕命运,着重探讨了维也纳城的伦理混乱,以及在主政者的伦理秩序重构中个人私通者由悲而喜和公共淫乱者由喜而悲的命运转向,旨在指出在西方前现代社会中,对基督教伦理规范的认同与否决定着个人的命运转向。  相似文献

A challenge for large‐scale environmental health investigations such as the National Children's Study (NCS), is characterizing exposures to multiple, co‐occurring chemical agents with varying spatiotemporal concentrations and consequences modulated by biochemical, physiological, behavioral, socioeconomic, and environmental factors. Such investigations can benefit from systematic retrieval, analysis, and integration of diverse extant information on both contaminant patterns and exposure‐relevant factors. This requires development, evaluation, and deployment of informatics methods that support flexible access and analysis of multiattribute data across multiple spatiotemporal scales. A new “Tiered Exposure Ranking” (TiER) framework, developed to support various aspects of risk‐relevant exposure characterization, is described here, with examples demonstrating its application to the NCS. TiER utilizes advances in informatics computational methods, extant database content and availability, and integrative environmental/exposure/biological modeling to support both “discovery‐driven” and “hypothesis‐driven” analyses. “Tier 1” applications focus on “exposomic” pattern recognition for extracting information from multidimensional data sets, whereas second and higher tier applications utilize mechanistic models to develop risk‐relevant exposure metrics for populations and individuals. In this article, “tier 1” applications of TiER explore identification of potentially causative associations among risk factors, for prioritizing further studies, by considering publicly available demographic/socioeconomic, behavioral, and environmental data in relation to two health endpoints (preterm birth and low birth weight). A “tier 2” application develops estimates of pollutant mixture inhalation exposure indices for NCS counties, formulated to support risk characterization for these endpoints. Applications of TiER demonstrate the feasibility of developing risk‐relevant exposure characterizations for pollutants using extant environmental and demographic/socioeconomic data.  相似文献

项目教学法是德国"双元制"职业院校中盛行的教学模式,但多用于工科专业。自引入我国以来,对于工科类高职院校来说,效果非常明显,但对于财经类专业应用效果不尽人意。本文选取财经类专业岗位财务管理岗位实际工作情境之一——筹资,以项目教学法为基础,构建了包括教学情境的设计、学生学习步骤一览表的制定、学生学习步骤计划书的设计、学生自我测试及测试题库的设计、工作任务的设计、参考信息的提供、学习方法和策略的指导、项目成果的展示要求、教学评价方法的制定共9个部分组成的课堂教学体系。  相似文献

This paper discusses the value of action learning for social work supervisors. Recent years have seen renewed focus on supervision as a reflective space and some indications that the tide may be turning in regard to the dominance of managerial priorities within the supervision of direct practice. It is less evident that a similar shift is taking place for supervisors themselves and, anecdotally, many describe their own supervision as having a business focus with limited scope for reflective dialogue. While the traditional functions of supervision need to adapt to fit the responsibilities of those in management positions, it remains true that these staff provide a vital containing role within the organisational hierarchy. For that to be sustained, it is important that supervisors have space and structure within which to process the emotional, intellectual and practical challenges of their work. The integration of action learning sets within post-qualifying courses for supervisors has demonstrated a useful dual function. Firstly, they provide an effective model for group supervision, facilitating in-depth reflection on complex practice issues. Secondly, they offer managers a peer supervision forum; a safe place to explore dilemmas and share the vulnerabilities which belong to management roles as well as practice.  相似文献

A stable money demand function is essential when using monetary aggregate as a monetary policy. Thus, there is need to examine the stability of the money demand function in Nigeria after the deregulation of the financial sector. To achieve this, the study employed CUSUM (cumulative sum) and CUSUMSQ (CUSUM of square) tests after using autoregressive distributive lag bounds test to determine the existence of a long run relationship between monetary aggregates and their determinants. Results of the study show that a long-run relationship holds and that the demand for money is stable in Nigeria. In addition, the inflation rate is found to be a better proxy for an opportunity variable when compared to interest rate. The main implication of the study is that interest rate is ineffective as a monetary policy instrument in Nigeria.  相似文献

台湾在二十世纪的八十年代末至九十年代,特别是在解除戒严体制之后,越来越多的人开始关心他们所居住的社区,出现了所谓的社区总体营造。及至至今,台湾的社区总体营造可谓风生水起,对台湾的发展,特别是台湾人民的生活起到了非常重要的作用。在当今经济社会全球一体化的大背景下,台湾社区总体营造模式能成功实施并延续至今,这对于大陆地区所开展的新农村建设具有重要的借鉴价值。  相似文献
