In this paper, we consider experimental situations in which a regular fractional factorial design is to be used to study the effects of m two-level factors using n=2m−k experimental units arranged in 2p blocks of size 2m−k−p. In such situations, two-factor interactions are often confounded with blocks and complete information is lost on these two-factor interactions. Here we consider the use of the foldover technique in conjunction with combining designs having different blocking schemes to produce alternative partially confounded blocked fractional factorial designs that have more estimable two-factor interactions or a higher estimation capacity or both than their traditional counterparts. 相似文献

Concern about the participation of incompetent subjects in psychiatric research has grown in the last several years. In response, the National Bioethics Advisory Commission (NBAC) recommended in its recent report that all investigations involving persons with mental disorders that may be associated with cognitive impairment that may pose greater than minimal risk to subjects utilize independent assessors to verify the capacities of subjects prior to entry into the study. This recommendation poses several problems for the conduct of research and the protection of research subjects. First, it fails to target that group of subjects most likely to be at risk for incapacity. Second, it focuses on too broad a range of research projects, many of which pose little risk to participants. The substantial costs of this approach are therefore not likely to be outweighed by concomitant benefits. In place of the NBAC recommendation, the author proposes a more flexible system of capacity assessment, designed to balance the costs with a greater likelihood of achieving meaningful protection for research subjects with mental disorders. 相似文献

ABSTRACTIt is time for action by leaders across higher education to strengthen quality improvement (QI) in college health, in pursuit of better care, better health, and increased value – goals closely linked to students' learning and success. The size and importance of the college student population; the connections between wellbeing, and therefore QI, and student success; the need for improved standards and greater accountability; and the positive contributions of QI to employee satisfaction and professionalism all warrant a widespread commitment to building greater capacity and capability for QI in college health. This report aims to inspire, motivate, and challenge college health professionals and their colleagues, campus leaders, and national entities to take both immediate and sustainable steps to bring QI to the forefront of college health practice – and, by doing so, to elevate care, health, and value of college health as a key pathway to advancing student success. 相似文献

大宗物资集中采购的调运计划研究 总被引:3,自引:1,他引:3
大宗物资调运问题是一个受多因素影响的复杂问题,一般来讲,其调运数量大、地域跨度大、时间紧。如何协调供需以及运输能力,保证物资采购部门的经济利益是本文所要研究的问题。本文首先给出了大宗物资集中采购的调运模式,然后针对采购部门在大宗物资调运过程中遇到的困难,为采购部门提出了以获取数量折扣、准时采购、降低库存成本和协调运输能力为准则的调运计划模型。数值计算表明应用本文所建模型编制调运计划能够达到降低采购费用、协调运输能力的目的,为大宗物资调运计划的编制提供了一种较为有效的方法。 相似文献

Email: John_Corden{at}msn.com Summary In this paper, the authors consider the promotion of Prochaskaand DiClementes transtheoretical model of change (theTTM) to the assessment of parenting capacity, within the literaturewhich supports the Framework for Assessment. A number of criticismsof the model, originating from within its original area of applicationare reviewed, and considered in the context of the assessmentof parenting. The authors go on to raise certain questions aboutthe validity of transferring this model from the field of addictivebehaviours to that of parenting and child protection. 相似文献

人口与环境可持续发展 总被引:1,自引:0,他引:1

人口环境系统是人口、资源、环境组成的对立统一的自然社会系统 ,是高度融合的有机整体。人口环境系统动因包括人口环境运动的推动、关系的调整和规律的作用。地球环境系统被人口压力突破后表现出矛盾的滞后性、影响的多重性和经济陷于衰退。人口过多、素质偏低和老龄化加快三症并发 ,成为中国人口与环境发展的独特现象。环境的作用包括给人类提供自然资源、自净功能或环境容量 ,提供舒适性环境的精神享受。环境问题的实质是人类索取超过资源本身、排污超过环境自净能力、自然资源耗竭超过极限便不可逆转。中国传统工业是一柄双刃剑 ,高投入、高消费求得增长 ,物耗和污染代价巨大。环境污染的主因是决策者和建设者缺乏可持续发展意识。可持续发展是实现人口与环境协调发展的科学、合理的社会结构范式。可持续发展可形象地比作人类发展坐标轴 :纵坐标是时间上的连续性 ,即兼顾当代与后代 ,控制人口 ,提高素质 ,珍惜资源 ,保护环境 ;横坐标是空间上的立体性 ,即精神文明、物质文明、社会文明、生态文明并举 ;轴心是人口与环境关系的良性互动。 相似文献

"自然人"作为现代民法中首要的民事主体,其本身的建构以及与其他制度的相互联系,无不体现文明的法治对人的终极关怀.故从普遍人性中的合理因素入手,探讨自然人制度建构对维护人性的的应有功能是有意义的. 相似文献
