Interval estimation for conformance proportions of multiple quality characteristics

A conformance proportion is an important and useful index to assess industrial quality improvement. Statistical confidence limits for a conformance proportion are usually required not only to perform statistical significance tests, but also to provide useful information for determining practical significance. In this article, we propose approaches for constructing statistical confidence limits for a conformance proportion of multiple quality characteristics. Under the assumption that the variables of interest are distributed with a multivariate normal distribution, we develop an approach based on the concept of a fiducial generalized pivotal quantity (FGPQ). Without any distribution assumption on the variables, we apply some confidence interval construction methods for the conformance proportion by treating it as the probability of a success in a binomial distribution. The performance of the proposed methods is evaluated through detailed simulation studies. The results reveal that the simulated coverage probability (cp) for the FGPQ-based method is generally larger than the claimed value. On the other hand, one of the binomial distribution-based methods, that is, the standard method suggested in classical textbooks, appears to have smaller simulated cps than the nominal level. Two alternatives to the standard method are found to maintain their simulated cps sufficiently close to the claimed level, and hence their performances are judged to be satisfactory. In addition, three examples are given to illustrate the application of the proposed methods.     

领导干部党性修养评价机制研究

建立健全领导干部党性修养评价机制,是加强党的执政能力建设,建设高素质执政骨干队伍的客观需要。坚定的政治信念、牢固的党纪意识、严谨的自律能力、优秀的道德品质和勤勉的工作作风是评价领导干部党性修养的主要内容。要明确评价领导干部党性修养的指导思想、评价主体和评价原则,要建立健全领导干部党性修养的评价指标体系,不断探索科学的评价领导干部党性修养的方式方法。     

伸展构造背景下倾角资料的构造解释

系统总结了在伸展构造背景下，导致反映构造特征的地层倾角模式复杂化的多种因素。沉积相的不同、岩性变化、井眼状况和测井作业时间等多种因素都可能使地层倾角资料复杂化。进一步指出在拉张盆地中，进行倾角资料的构造解释，必须了解其构造样式的多样性和复杂性，解释存在的多解性。重点解剖了铲式断层在横剖面情况下，对于不同构造位置下的倾角模式。详细分析了一个倾角模式对应多种构造样式的倾角构造解释实例。倾角资料的构造解释应是综合解释，既要综合井筒的相关地质资料，又要综合测井与地质知识，还必须考虑综合地震资料。     

都市独生子女特性分析

计划生育政策下的当今都市环境中生存的独生子女群体,其特性大异于前代人,压力源亦异于前人,所思所念以及心理困扰极具特点,进入青春期后特征尤为明显。抓住当今都市独生子女的本质特征,对未来青少年教育的方向及方式具有特殊意义和价值。     

《未成年人保护法(修订草案)》述评与完善

未成年人保护法修订草案积极回应了当前面临的未成年人法律困境和现实诉求,提出和细化了许多具体举措,尤其是新增了未成年人最大利益原则,确立了国家监护制度,体现了重大的进步。在立法关系上,无论是与预防未成年人犯罪法草案,还是与现行的其他涉及未成年保护的相关法律,未保法草案均与之存在着不协调问题。未保法草案的修法思路亟待从“理想化的统领和难以操作的补漏”转向务实性的“重点明晰和问题导向”,亦即未成年人保护法的“福利法化”并呼应预防未成年人犯罪法的“少年法化”。未保法草案的体例布局未能充分体现立法本意和修法初衷,在概念厘清、文本形式、涵盖内容与表达逻辑上均需要进一步改进和完善。     

Modifications of sequential designs in bioequivalence trials

Bioequivalence (BE) studies are designed to show that two formulations of one drug are equivalent and they play an important role in drug development. When in a design stage, it is possible that there is a high degree of uncertainty on variability of the formulations and the actual performance of the test versus reference formulation. Therefore, an interim look may be desirable to stop the study if there is no chance of claiming BE at the end (futility), or claim BE if evidence is sufficient (efficacy), or adjust the sample size. Sequential design approaches specially for BE studies have been proposed previously in publications. We applied modification to the existing methods focusing on simplified multiplicity adjustment and futility stopping. We name our method modified sequential design for BE studies (MSDBE). Simulation results demonstrate comparable performance between MSDBE and the original published methods while MSDBE offers more transparency and better applicability.

如何促进产业集群发展?——美国亚利桑那州产业集群发展模式分析

1980年代末至1990年代初,美国亚利桑那州经济遭遇严重衰退,地区经济发展面临转型压力。1992年,亚利桑那州实施了产业集群战略,成功推动了地区经济的复苏和转型,并使其成为之后十余年美国经济增长最快的地区之一。通过对亚利桑那州产业集群战略的制定、调整和集群发展特征的深入分析发现,亚利桑那州产业集群的发展得益于科学的战略设计和以"技术密集型中小企业+企业网络组织"为双驱动的发展模式,而政府在这一过程中只扮演着"组织者"和"协调者"的角色。这对中国产业集群的发展具有重要的借鉴意义。     

The disembedded digital economy: Social protection for new economy employment in China

This research focuses upon employment in the new economy, exploring labour protection and social protection in the digital age in China. Through an empirical survey conducted in three Chinese cities, social insurance and the labour rights of employees in the digital economic sector, such as gig employment, e-commerce, and various other forms of online employment, have been examined in-depth. This study reveals new regulatory loopholes in the digital labour market, which have substantially eroded the basis of social policy arrangements in China, “softening” participation in social insurance branches and compliance with labour regulations remarkably. Drawing upon the theoretical concepts of Polanyi on embeddedness and disembeddedness, we argue that the digital employment sector in China has been increasingly disembedded from social institutions and social control. The new configuration in the digital field of social policy requires novel conceptual models and institutional settings to cope with increasing social risks in virtual spaces.
