中国及TTIP国家贸易便利化水平测评

准确测度中国与TTIP主要成员国之间的贸易便利化差异,便于深刻把握TIP催生的国际贸易便利化新趋势,应对全球贸易规则变迁的挑战.文章首先构建了贸易便利化测评指标体系,采用《全球竞争力报告》《腐败指数》以及《世界竞争力年鉴》的相关数据,对2008-2014年TTIP主要成员国及中国的贸易便利化水平进行了对比测评.研究发现,虽然中国的贸易便利化水平整体上升了,但与TTIP发达成员国的差距依然较大,在口岸效率、海关环境、规制环境和电子商务方面均低于其平均水平.为此,中国应进一步简化海关程序和手续,改善海关环境,提升政策制定的透明度,加大对电子商务中的新信息技术的应用力度,防范TTIP区域内贸易转移效应对我国的影响.     

FDI 对安徽省装备制造业发展的影响分析

外商直接投资（FDI）在拓宽国内资金需求渠道的同时,具有较强的技术溢出效应,迎合了装备制造业资本和技术密集的双重特征。当前,安徽省装备制造业处在资本密集型占主导的发展阶段,对 FDI的偏好性较强。研究表明,安徽省装备制造业与FDI间具有较强的相关性,FDI能够有效促进安徽省装备制造业发展,但安徽省装备制造业对FDI的吸引力较弱,且各具体行业对 FDI依赖程度存在较大差异。据此提出相应的建议,一方面,安徽省应注重装备制造业转型升级,提升行业整体竞争力;另一方面,要优化投资环境,增强安徽省装备制造业对FDI的引致能力。     

Distribution of the two‐sample t‐test statistic following blinded sample size re‐estimation

We consider the blinded sample size re‐estimation based on the simple one‐sample variance estimator at an interim analysis. We characterize the exact distribution of the standard two‐sample t‐test statistic at the final analysis. We describe a simulation algorithm for the evaluation of the probability of rejecting the null hypothesis at given treatment effect. We compare the blinded sample size re‐estimation method with two unblinded methods with respect to the empirical type I error, the empirical power, and the empirical distribution of the standard deviation estimator and final sample size. We characterize the type I error inflation across the range of standardized non‐inferiority margin for non‐inferiority trials, and derive the adjusted significance level to ensure type I error control for given sample size of the internal pilot study. We show that the adjusted significance level increases as the sample size of the internal pilot study increases. Copyright © 2016 John Wiley & Sons, Ltd.

劳务输出与脱贫致富

长期以来 ,有关方面均把贫困地区脱贫致富寄望于劳务输出。短期看来 ,劳务输出确能在一定程度上缓解贫困压力 ,但长期而言 ,劳务输出并不能从根本上解决贫困地区的脱贫致富问题。这是由劳力输出的限度、制约条件、实际效果及贫困的根本原因决定的。贫困地区脱贫的根本出路在于 :立足并开发贫困地区 ,走政府推进型脱贫致富之路。为此 ,当务之急须认真解决好三个问题 :( 1 )制定并实施开发贫困地区的战略 ;( 2 )国家加大对贫困地区的投入 ;( 3)地方政府真抓实干领导脱贫     

A comparative study of confidence intervals to assess biosimilarity from analytical data

Assessment of analytical similarity of tier 1 quality attributes is based on a set of hypotheses that tests the mean difference of reference and test products against a margin adjusted for standard deviation of the reference product. Thus, proper assessment of the biosimilarity hypothesis requires statistical tests that account for the uncertainty associated with the estimations of the mean differences and the standard deviation of the reference product. Recently, a linear reformulation of the biosimilarity hypothesis has been proposed, which facilitates development and implementation of statistical tests. These statistical tests account for the uncertainty in the estimation process of all the unknown parameters. In this paper, we survey methods for constructing confidence intervals for testing the linearized reformulation of the biosimilarity hypothesis and also compare the performance of the methods. We discuss test procedures using confidence intervals to make possible comparison among recently developed methods as well as other previously developed methods that have not been applied for demonstrating analytical similarity. A computer simulation study was conducted to compare the performance of the methods based on the ability to maintain the test size and power, as well as computational complexity. We demonstrate the methods using two example applications. At the end, we make recommendations concerning the use of the methods.     

Underlying processes of SCCT: Mediating roles of preventability,blame, and trust

Despite the prevalence of the situational crisis communication theory (SCCT; Coombs, 2007) in crisis communication research, few SCCT-based studies have examined how different crisis types affect post-crisis reputation. This study, therefore, attempts to uncover the underlying processes of SCCT. Specifically, this study examined preventability, blame, and trust as potential mediators of crisis type and organizational post-crisis reputation. A between-subjects experimental study (crisis type: victim vs. accidental vs. preventable) was conducted with 329 college students. The results revealed that crisis type had no direct effects on reputation, but it did affect preventability, blame, and trust. More significantly, the results showed that crisis type indirectly affected reputation in two distinct ways: (1) via a sequence of preventability and blame and (2) via trust. The study includes a discussion of theoretical and practical implications.     

The laws of large numbers for Pareto-type random variables with infinite means

In this paper, we consider the laws of large numbers for NSD random variables satisfying Pareto-type distributions with infinite means. Based on the Pareto-Zipf distributions, some weak laws of large numbers for weighted sums of NSD random variables are obtained. Meanwhile, we show that a weak law for Pareto-Zipf distributions cannot be extended to a strong law. Furthermore, based on the two tailed Pareto distribution, a strong law of large numbers for weighed NSD random variables is presented. Our results extend the corresponding earlier ones.     

Distress or disability? Could a theoretical framework drawn from disability studies be a way forward when trying to understand experiences of oppression on the grounds of mental distress?

This article explores whether it is possible to use a theoretical framework drawn from disability studies to understand experiences of social oppression on the grounds of mental distress. Thomas’ extended social relational theoretisation of disablism was used in a PhD project concerned with experiences of mental distress. The tentative conclusion was that Thomas’ conceptualisation of disablism and impairment could offer a way of improving understanding of mental distress and oppression on the grounds of mental distress. However, Thomas and Reeve’s theorisation of the different forms of disablism was not readily transferred to the field of mental distress. Thus, tentative definitions of the different forms of disablism in relation to the field of mental distress were created. Perceived impairment type and disablism appear to be interconnected, and one has to acknowledge what kind of perceived impairment type one is focusing on when theorising disability and the different types of disablism.
