A fiducial approach for testing the non-inferiority of proportion difference in matched-pairs design

The non-inferiority of one treatment/drug to another is a common and important issue in medical and pharmaceutical fields. This study explored a fiducial approach for testing the non-inferiority of proportion difference in matched-pairs design. Approximate tests constructed using fiducial quantities with a combination of different parameters were proposed. Four simulation studies were employed to compare the performance of fiducial tests by comparing their type I errors and powers. The results showed that fiducial quantities with parameter $0.6\le w_1\le 0.8$ performed satisfactorily from small to large samples. Therefore, the fiducial tests could be recommended for practical applications. The recommended fiducial tests might be a competitive alternative to other available tests. Three real data sets were analyzed to illustrate the proposed methods were competitive or even better than other tests.     

大学教学中教师专业自我建构的实践理性——帕克·帕尔默教师专业发展思想探析

美国学者帕克·帕尔默在论述教师专业发展问题时,对大学教师在教学过程中的专业自我建构进行了具有实践理性意蕴的多向度阐释,强调只有将“学科”“学生”与“自我”融入自身的专业自我建构,才能使大学教师的专业自我发展渐入佳境,复而推动其教学的改进与提升。帕尔默对于实现这“三重融合”的现实难题进行剖析,并提出应对之策,为处于专业发展中的大学教师提供有益参考。     

Avoiding Covid-19 risk information in the United States: The role of attitudes,norms, affect,social dominance orientations,and perceived trustworthiness of scientists

This study seeks guidance from the planned risk information avoidance model to explore drivers of risk information avoidance in the context of COVID-19. Data were collected early during the pandemic. Among our most notable results is that participants who are more oriented toward social dominance and are more skeptical of scientists’ credibility have (1) more supportive attitudes toward risk information avoidance and (2) feel social pressure to avoid risk information. The findings of this study highlight how the role of skepticism in science and intergroup ideologies, such as social dominance, can have important implications for how people learn about health-related information, even in times of heightened crisis.     

Technological Innovation and Employment Reallocation

The paper describes the dynamics of employment at a firm and sector level in French industry and examines how far technological innovation can give account of it. We use a sample of 15,186 firms, over the period 1986–90. The two facts we want to explain at a firm and sector level are the net change in employment and the micro turmoil (transfers between competing firms). Innovating firms and sectors create jobs more than others over the medium run (5 years). Process innovation is more about job creation than product innovation at the firm level, but the converse is true at the sector level. This paradox is probably due to substitution effects (creative destruction).     

Attachment insecurities and under-commitment in distressed couples: The role of positive and negative partner behaviors

Research has rarely considered intermediate variables in the association between attachment insecurities and relationship commitment. Based on attachment theory and Rusbult's Investment Model, we tested whether positive and negative partner behaviors explain this association in 91 distressed couples undergoing therapy. Path analyses based on the Actor–Partner Interdependence Model revealed that individuals with attachment avoidance reported perceiving fewer positive behaviors from their partner, which was associated with their own higher under-commitment. Partners of individuals with avoidance also reported perceiving fewer positive partner behaviors, which was in turn associated with their own higher under-commitment. Partners of individuals with attachment anxiety perceived more positive behaviors from their partner, which was associated to their own lower under-commitment. Perceived negative partner behaviors were only directly associated with higher under-commitment. These findings imply that perceived positive partner behaviors may be a key aspect to target in relationship therapy in couples who present with high attachment insecurities.
