论魏晋南朝“势族”内涵的变迁

西晋人刘毅在论及当时九品中正制有八损时曾说“上品无寒门,下品无势族”,后来沈约在《宋书·恩幸传》中曾引用此语并将其改为“下品无高门,上品无贱族”.这绝非是简单的同义词替换,而是因为在魏晋南朝三百多年的历史进程中,这些词语的内涵不断被历史本身所更新,正所谓“一切真历史都是当代史”.以“势族”一词在魏晋南朝文献中出现的具体语境为例,其所指先后经历汉末的地方豪族、西晋中央政府中的势力集团、南朝迅速兴起的寒人群体等三个阶段.这个变化过程与门阀势力在此时期的兴起、盛衰基本保持同步.故到沈约修《宋书》之时,不得不根据时代的变化而对词语作出更换.     

Nonstandard maternal work schedules: Implications for African American children's early language outcomes

In this study, observed maternal positive engagement and perception of work–family spillover were examined as mediators of the association between maternal nonstandard work schedules and children's expressive language outcomes in 231 African American families living in rural households. Mothers reported their work schedules when their child was 24 months of age and children's expressive language development was assessed during a picture book task at 24 months and with a standardized assessment at 36 months. After controlling for family demographics, child, and maternal characteristics, maternal employment in nonstandard schedules at the 24-month timepoint was associated with lower expressive language ability among African American children concurrently and at 36 months of age. Importantly, the negative association between nonstandard schedules and children's expressive language ability at 24 months of age was mediated by maternal positive engagement and negative work–family spillover, while at 36 months of age, the association was mediated only by negative work–family spillover. These findings suggest complex links between mothers’ work environments and African American children's developmental outcomes.     

论贫困家庭的高等教育投资和收益

我国实行高等教育收费制度以后,贫困家庭承受着巨大的经济压力。虽然贫困家庭的投资能够获得“收益性”补偿,但也面临着种种风险。因此,高校在投入上应把贫困家庭的经济作为重要参数之一,进行相应的资源配置改革,从而提高大众高等教育的个人收益。

Traversing the Challenges of Conducting Research with Young, Immigrant Children: The Case of Korean Children

Based on a qualitative study on young Korean immigrant children’s interpretation of American popular culture, this paper reflects on the researchers’ role by examining the research challenges faced. Prior to discussing the research obstacles in conducting the study, we begin with briefly describing its methodology and design. Next, we discuss the various obstacles we encountered when conducting our study and howwe attempted to overcome these dilemmas by discussing two major struggles during the research process: a) the relationships between the researchers and our young participants, and b) the cultural sensitivity that was needed in initially gaining permission from and working with the parents of our informants. It then illuminates how the researchers attempted to cope with such difficulties by rethinking a researchers’s role emphasizing the importance of cultural context in research. Finally, the paper provides some discussions and implications based on our research experiences.     

Investigating the Power of Authentically Caring Student-Teacher Relationships for Latinx Students

Culturally responsive and authentically caring pedagogy is vitally important to academic success for Latinx students. This type of teaching is based on reciprocal relationships between students and teachers, and incorporates students’ funds of knowledge. This qualitative case study brings the voices of Latinx students to the forefront by examining how their teachers help create “funds of caring” for the students by cultivating authentically caring relationships, and by highlighting what these relationships mean for the students. Findings show that teachers can make school a meaningful and positive experience for Latinx youth by interacting with students in authentically caring ways.     

La Transición: parent perspectives on transition for Latino youth with intellectual and developmental disabilities

The transition to adulthood can be a challenging time for adolescents with intellectual and developmental disabilities. Its complexity, however, may be magnified for families who have immigrated to the United States. This study examined the transition expectations and experiences of six first-generation, Latino parents and their transition-aged (14–22) children with intellectual disability, autism, and/or multiple disabilities. Through individual interviews held in Spanish or English, parents offered insights into (1) their visions of success for their child, (2) the distinct barriers they face as immigrant families, and (3) their suggestions for schools and adult agencies related to supporting strong transitions. Their portraits of desired outcomes were quite individualized and reflected high expectations. Factors identified as inhibiting successful transitions included persistent language barriers, the views of certain professionals and community members, and exclusion from typical school experiences. Parents encouraged schools to support family advocacy, foster greater student independence, expand adult programming, and reduce segregated educational placements. We present implications for educators on working with Latino families, as well as offer recommendations for future research.     

Video gaming as digital media,play, and family routine: implications for understanding video gaming and learning in family contexts

While a number of studies have investigated learning associated with video gaming in out-of-school settings, only recently have researchers begun to explore gaming and learning in the contexts of home and family life. This paper discusses three different frameworks within which we can situate video games and learning at home: (a) video gaming as digital media, (b) video gaming as play, and (c) video gaming as family routine. Each framework brings different issues related to learning into focus, and contributes new insights into the role gaming plays in the lives of children, adults, and families as a whole.
