残疾人创业的信任环境重构——基于团队特征的视角

推动残疾人成功创业已成为各国促进残疾人就业率提升的一个有效手段,但创业成功并非易事,残疾人创业所面临的信息沟通不畅、信任环境缺失等问题直接影响创业的成功率。本文通过构建相关变量的有调节效应的回归模型,深入探讨了影响残疾人创业的情景因素,研究结果显示,残疾人创业团队的外部信任环境重构和创业团队自信心的建立对创业成功有显著的正向影响。     

Asian children’s verbal development: A comparison of the United States and Australia

Using longitudinal cohort studies from Australia and the United States, we assess the pervasiveness of the Asian academic advantage by documenting White-Asian differences in verbal development from early to middle childhood. In the United States, Asian children begin school with higher verbal scores than Whites, but their advantage erodes over time. The initial verbal advantage of Asian American children is partly due to their parent’s socioeconomic advantage and would have been larger had it not been for their mother’s English deficiency. In Australia, Asian children have lower verbal scores than Whites at age 4, but their scores grow a faster rate and converge towards those of Whites by age 8. The initial verbal disadvantage of Asian Australian children is partly due to their mother’s English deficiency and would have been larger had it not been for their Asian parent’s educational advantage. Asian Australian children’s verbal scores grow at a faster pace, in part, because of their parent’s educational advantage.     

比较法视野下我国搜查措施之理论反思

我国有证搜查还处于内部控制、自我约束和事后监督的阶段。被搜查者的合法权利不得不严重依赖于侦查人员搜查的文明程度。而无证搜查立法的拘谨与侦查实践的现实需要之间存在显著的差异。我国搜查措施所存在的问题,显示出搜查措施对侦查机关的规范和约束力度还处于较低的水平,对被搜查者权利的保障仍有所不足。我国不仅需要完善有证搜查制度,而且更需要建立和规范以同意搜查为核心的无证搜查制度,以追随刑事诉讼现代化之步伐,实现法治中国之梦想。     

Multi-objective optimization in partitioning the healthcare system of Parana State in Brazil

Motivated by a proposal of the local authority for improving the existing healthcare system in the Parana State in Brazil, this article presents an optimization-based model for developing a better system for patients by aggregating various health services offered in the municipalities of Parana into some microregions. The problem is formulated as a multi-objective partitioning of the nodes of an undirected graph (or network) with the municipalities as the nodes and the roads connecting them as the edges of the graph. Maximizing the population homogeneity in the microregions, maximizing the variety of medical procedures offered in the microregions, and minimizing the inter-microregion distances to be traveled by patients are considered as three objective functions of the problem. An integer-coded multi-objective genetic algorithm is adopted as the optimization tool, which yields a significant improvement to the existing healthcare system map of the Parana State. The results obtained may have a strong impact on the healthcare system management in Parana. The model proposed here could be a useful tool to aid the decision-making in health management, as well as for better organization of any healthcare system, including those of other Brazilian States.     

模拟混相驱动态的拟四组分模型

通常模拟混相驱动态采用组分模型,由于组分模型求解工作量大,计算速度慢,要求输入的参数较多,而这些参数很难取全取准,同时组分模型不易被油藏工程师所掌握。因此,介绍了一种模拟混相驱动态的模拟模型,该模型是在黑油模型基础上发展起来的拟四组分模型,它兼有黑油模型和多组分模型的某些优点,如黑油模型的稳定性好和计算速度快、组分模型的可模拟凝析气藏和混相驱等;给出了数学模型及各种物理参数以及混相流体性质的处理方法。该模型还以SPE为例进行计算,结果与SPE的结果一致,从而验证了本模型的可靠性。     

企业家演讲中的隐喻论证

隐喻性表达不仅可以使演讲变得形象生动，而且有时候会产生很强的劝说功能。在概念隐喻理论与图尔敏论证模型的基础上，从隐喻论证和语用论辩的角度，对企业家（以马云为例）演讲中所存在的隐喻性表达进行分析，探讨隐喻论证中的“反驳”要素，以及隐喻论证的劝说机制。     

抽汲井试井分析数学模型的建立及精确解

根据抽汲井试井工艺过程及其特点,采用已知上一次抽汲结束时的地层压力分布规律建立下一次抽汲数学模型的方法,建立了抽汲井试井分析数学模型,并在Laplace空间求解出了相应的精确解。将这一成果应用于长庆油田之中,结果表明:该理论能描述抽汲井的井底压力瞬变性及抽汲期井底压力变化无规律性的特征,符合实际测试工艺情况,弥补了抽汲井试井这一空白;提高了该类井试井的解释率和解释结果的可信度。同时,利用该理论还可计算抽汲过程中任一时刻的井底压力和关井时刻的井底压力,解决了抽汲井难以计算关井时刻井底压力的问题。

Sexual Beliefs and Sexual Functioning: The Mediating Role of Cognitive Distraction

Dysfunctional sexual beliefs are vulnerability factors for sexual dysfunction. This cross-sectional study aimed to test the mediating role of cognitive distraction on the relationship between dysfunctional sexual beliefs about sexual functioning shared by men and women and sexual function. The authors used a sample of 421 cisgender heterosexual participants involved in a monogamous relationship. The hypothesized mediation model was tested using a bootstrapped cross product of coefficients approach. Results showed a significant negative, indirect effect between dysfunctional sexual beliefs and women's sexual function through cognitive distraction. The discussion of this study highlights the importance of cognitive factors in sexual functioning.     

Joint Modelling of Survival and Longitudinal Data with Informative Observation Times

In this paper, we consider the joint modelling of survival and longitudinal data with informative observation time points. The survival model and the longitudinal model are linked via random effects, for which no distribution assumption is required under our estimation approach. The estimator is shown to be consistent and asymptotically normal. The proposed estimator and its estimated covariance matrix can be easily calculated. Simulation studies and an application to a primary biliary cirrhosis study are also provided.
