A Study on the New Generation of Migrant Workers＇ Friendship

在新生代农民工的社会关系中,友缘是一种涵盖范围广并具有特殊性的关系形态。以往的研究大多将“朋友”与“亲戚”放在一起并称为“亲友”,但这一概念在日后的演变中逐渐离析。根据问卷调查的数据,友缘（化）关系可以分为三种类型：“友缘化关系”,“初级友缘关系”,“次级友缘关系”。不管何种类型,在新生代农民工融入城市的过程中都会发生友缘社会资本的变动。一方面．个体借助“友缘链”扩展社会资本,通过偶然机会结识朋友的比例很高。另一方面,不可抗的社会事件是造成友缘社会资本流失的重要原因。     

Popularity breeds contempt: The evolution of reputational dislike relations and friendships in high school

In this study, we examined the dynamics of the perception of “dislike” ties (reputational dislike) among adolescents within the contexts of friendship, perceived popularity, substance use, and Facebook use. Survey data were collected from a longitudinal sample of 238 adolescents from the 11th and 12th grades in one California high school. We estimated stochastic actor-based network dynamic models, using reports of reputational dislike, friendships, and perceived popularity, to identify factors associated with the maintenance and generation reputational dislike ties. The results showed that high-status adolescents and more frequent Facebook users tended to become perceived as or stay disliked by their peers over time. There was a tendency for friendships to promote the creation and maintenance of reputational disliking but not vice versa. Adolescents tended to perceive others as disliked when their friends also perceived them as disliked. There was no evidence that either cigarette smoking or drinking alcohol affected reputational dislike dynamics. This study highlights the important role that the hierarchical peer system, online peer context, and friendships play in driving information diffusion of negative peer relations among adolescents.     

Analytic strategies for longitudinal networks with missing data

Missing data are often problematic when analyzing complete longitudinal social network data. We review approaches for accommodating missing data when analyzing longitudinal network data with stochastic actor-based models. One common practice is to restrict analyses to participants observed at most or all time points, to achieve model convergence. We propose and evaluate an alternative, more inclusive approach to sub-setting and analyzing longitudinal network data, using data from a school friendship network observed at four waves (N = 694). Compared to standard practices, our approach retained more information from partially observed participants, generated a more representative analytic sample, and led to less biased model estimates for this case study. The implications and potential applications for longitudinal network analysis are discussed.     

The ‘right time’ – negotiating the timing of interviews with vulnerable young people

Participant retention is a key factor in determining the success of longitudinal research. Challenges in re-locating and retaining participants over the long term are major issues for researchers working with young people who face adversity and experience frequent changes in circumstances. This article reports on a study of vulnerable young people and their transition into adulthood. Rather than the more conventional schedule-based approach to locating and re-interviewing young people, a relational process, the ‘right time’ framework, was used to facilitate young people's involvement in the study. Embedded in the ‘right time’ framework is recognition of the diverse and fluctuating circumstances that shape young people's availability for interviews. Several case examples are considered which amplify the way that the ‘right time’ framework allowed the research to navigate around these circumstances. The case examples highlight the value young people attached to being involved in the research, the influence on the ‘right time’ of wider relational tensions for young people and the need to negotiate researcher status as a different sort of adult. The ‘right time’ framework contributed to a high retention rate in the study generating a more representative sample and enhancing the subsequent data analysis by providing valuable insights into the lives of these vulnerable young people.     

The Black male teacher: a 10-year content analysis of empirical research

ABSTRACT

The purpose of this study was to characterize the last decade of Black male teacher empirical research. The present study aimed to elucidate the most salient themes, commonalities, and departures in the literature on Black male educators. A quantitative content analysis was performed to systematically characterize the research trends present in this line of inquiry. The data were collected using an inductively generated coding scheme. A sample of n = 31 studies were identified and examined from articles published between 2006 and 2016. Then frequency data were computed to characterize the data under investigation. The study results indicate that Black male teacher research is nuanced and burgeoning, despite several lapses in article production. The results of this study contribute to the literature on Black male teacher recruitment, retention, and experiences by providing a survey of current research trends that suggest areas of strength, as well as challenges warranting further consideration.     

文学视角下的唐代诏敕研究--由唐武德九年六月至九月诏书看李世民弑兄夺权及李渊被迫让位的真相

初唐诏敕文是初唐时期皇帝于施政过程中发布的“王言政令”,是具有最高权威的下行政治公文,涉及到了当时的政治、经济、军事、律法、外交、教育、文化等多方面的史实,和《大唐创业起居注》、《唐太宗实录》等史籍一道,都属于第一手资料,史料价值很高,可补正史之阙。即便是那些旨在宣扬皇德的诏敕文,如皇帝的即位、改元、祭天、封禅诏书,也为我们考察当时的史实提供了很多有价值的线索。本文主要从文史结合的角度出发,通过考察唐武德九年六月至九月诏书,来挖掘其中隐藏的李世民弑兄夺权及李渊被迫让位的真相。

Adolescents’ perception of peer groups: Psychological,behavioral, and relational determinants

Adolescents’ social cognitive understanding of their social world is often inaccurate and biased. Focusing on peer groups, this study examines how adolescents’ psychological, behavioral, and relational characteristics influence the extent to which they accurately identify their own and others’ peer groups. Analyses were conducted with a sample of 1481 seventh- and tenth-grade Chinese students who are embedded with 346 peer groups. Overall, females and older students had more accurate perceptions. In addition, lower self-esteem, higher indegree centrality, and lower betweenness centrality in the friendship network predicted more accurate perception of one’s own groups, whereas higher academic performance and lower betweenness centrality in the friendship network predicted more accurate perception of others’ groups. Implications for understanding the connection between adolescents’ psychological and behavioral traits, social relationships, and social cognition are discussed.
