Family and school capital explaining regional variation in math and reading achievement

We know that inequality varies by region and also begins early in life. Bivariate data suggest that 5–14-year-old children in the 1994 National Longitudinal Survey of Youth (NLSY) score differently in reading and mathematics achievement depending on their region, with children in the South and West scoring lower. We combine literatures on regional bases of inequality and family and school capital to generate hypotheses explaining these differences. Analyses of covariance provide supportive evidence. For both outcomes among boys, the variation is explained by additive models including family and child social and human capital, although selected aspects of school capital are also influential; these models also explain math achievement among girls. A model including both additive and interactive effects explains regional differences in reading achievement for girls. We interpret these findings in terms of their implications for studying inequality in child achievement as well as for emphasizing the importance of regional inequality, particularly beyond the South versus non-South distinction.     

The Relationship between High School Sector and Educational Success: Focusing on the Social Background of Private High School Students

This study investigates the influence of high school sector on educational success in Japan. A range of previous research on disparities among high schools has revealed that high school rank (based on the academic ability of pupils, etc.) originated from the democratization of high school. However, given that the democratization of high school is supported by private high schools, high school sector may become a factor for high school ranking. The data used for the analysis are the 2005 National Survey of Social Stratification and Social Mobility (SSM) in Japan. The results indicate that students who enter private high schools have lower academic ability than students who enter public high schools. By contrast, private high school students have greater educational success than public high school students. Moreover, this study reveals that private high school students are generally from a higher social class than public high school students. Given that the use of entrance examinations for private junior high schools has been increasing since the 1990s, in the future, the effect of private schools on educational success may become stronger in not only high schools but also junior high schools. This study thus emphasizes the importance of paying greater attention to the relationship between educational success and the private and public school sectors.     

Marital Satisfaction,Family Emotional Expressiveness,Home Learning Environments,and Children's Emergent Literacy

The current study investigates associations among marital satisfaction, family emotional expressiveness, the home learning environment, and preschool‐aged children's emergent literacy skills among 385 Midwestern mothers and their children. Path analyses examined how marital satisfaction related to emotional expressiveness in the home and whether this path was associated with the home learning environment and children's literacy skills. Higher maternal satisfaction was associated with higher levels of positive and lower levels of negative family emotional expressiveness. Additionally, family emotional environments characterized by mothers with higher positive expression were related to better home learning environments, which in turn were associated with higher literacy skills in children. Study findings underscore the importance of marital and family processes when considering young children's academic development.     

人工智能生成物的著作权保护路径探析——兼评人工智能生成物著作权第一案

人工智能技术的发展对传统著作权制度带来了显著的冲击。以人工智能生成物著作权第一案为例,通过审视作品构成要件判断标准发现,独创性始终贯彻以人类作者为中心的评价标准,同时,智力成果要件则是认定人工智能生成物构成著作权法意义上作品与否的重要标准。从人类是否实际参与作品的创作过程来看,多数人工智能生成物不构成作品,而保护人工智能生成物的价值追求与邻接权制度的基本理念相适应,且邻接权制度的扩张趋势也为把人工智能生成物纳入其保护范畴创造了机会。建议立法通过扩张邻接权制度的权利内容与客体类型以对人工智能生成物提供必要保护。而在当前阶段,反不正当竞争法可以为人工智能生成物相关利益主体提供一定限度的过渡保护。     

Occupational Safety:

After a feedback condition, assigned (foreman-selected) and participative (worker-selected) goal-setting were examined to determine how they might augment the safety performance of 150 workers in 17 rooms of a paper mill. A statistical comparison of performance under assigned goal-setting, with that under baseline conditions of feedback-alone demonstrated a significant increase in the percentage of nonhazardous conditions but not of safe practices. Goal-setting by workers did not produce significant increases for either practices or conditions, and rates of injuries remained at the same reduced level as during feedback-alone. A visual analysis of a graphic plot of repeated performance measures suggested that trends established during feedback alone could account, in part, for the improvements. Possibly ceiling effects and the stated opinions of workers about various attributes of goal-setting may have been related to the outcomes.     

Target detection from a classical and a Bayesian viewpoint

Two approaches have been used for designing spatial surveys to detect a target. The classical approach controls the probability of missing a target that exists; a Bayesian approach controls the probability that a target exists given that none was seen. In both cases, information about the likely size of the target can reduce sampling requirements. In this paper, previous results are summarized and then used to assess the risk that Roman remains could be present at sites scheduled for development in Greater London.

The State of American Boyhood

The existence of a “boy crisis” in the United States is a topic of public policy debate. This study examines the state of American boyhood, using not only the commonly reviewed indicators of school achievement but also mental health, premature death, injury, delinquency, and arrests. Boys are in trouble in many areas: low rates of literacy, low grades and engagement in school, high dropout from school, and dramatically higher rates of placement in special education, suicide, premature death, injuries, and arrests. Girls, however, suffer from other problems, especially depression, suicidal ideation and attempts, and eating disorders, and are less likely to achieve at the very highest levels in mathematics and science. This study argues that both boys and girls suffer from characteristic problems, but the issues affecting boys are serious and neglected.

浅探建国初的戏曲改革及其对评剧的影响

戏曲改革是解放初中央政府发动的对戏曲艺术全方位改革的大举措,从剧目的创作、表演及演员的社会地位的提升都做出了相应的改进方案,从而使戏曲艺术绽放出新的活力和魅力。然而由于在改革的过程中,过于与政治相联系,脱离观众的审美情趣和品味,导致戏曲在取得成就的同时伴随着失误。在这场改革运动中,评剧由于正处于从不成熟走向成熟的发展阶段,迫切需要借助改革的力量向前迈进,因此,戏曲改革促使评剧艺术走向发展的顶峰。
