Social network and content analysis of the North American Carbon Program as a scientific community of practice

The North American Carbon Program (NACP) was formed to further the scientific understanding of sources, sinks, and stocks of carbon in Earth's environment. Carbon cycle science integrates multidisciplinary research, providing decision-support information for managing climate and carbon-related change across multiple sectors of society. This investigation uses the conceptual framework of communities of practice (CoP) to explore the role that the NACP has played in connecting researchers into a carbon cycle knowledge network, and in enabling them to conduct physical science that includes ideas from social science. A CoP describes the communities formed when people consistently engage in shared communication and activities toward a common passion or learning goal. We apply the CoP model by using keyword analysis of abstracts from scientific publications to analyze the research outputs of the NACP in terms of its knowledge domain. We also construct a co-authorship network from the publications of core NACP members, describe the structure and social pathways within the community. Results of the content analysis indicate that the NACP community of practice has substantially expanded its research on human and social impacts on the carbon cycle, contributing to a better understanding of how human and physical processes interact with one another. Results of the co-authorship social network analysis demonstrate that the NACP has formed a tightly connected community with many social pathways through which knowledge may flow, and that it has also expanded its network of institutions involved in carbon cycle research over the past seven years.     

Tolerance of Uncertainty: Links to Happenstance,Career Decision Self‐Efficacy,and Career Satisfaction

This study investigated the extent to which tolerance of uncertainty affects the relationship between happenstance skills and career satisfaction via career decision self‐efficacy. Moderated mediation analysis was conducted on data collected from 321 graduates (175 men, 146 women) of Korean universities making the school‐to‐work transition. Results showed that career decision self‐efficacy fully mediated the relationship between happenstance skills and career satisfaction. Furthermore, the moderation effect of tolerance of uncertainty had a significant impact on the relationship between happenstance skills and career decision self‐efficacy. Tolerance of uncertainty should be considered an important variable in happenstance career theory and intervention. Unplanned influences should also be considered important factors in the career decision‐making process.     

Producing information: communication and collaboration in the South African scientific community

Prior research has investigated the relationships between communication, collaboration and production of information/knowledge. Most of this research has been conducted either in developed countries where the internet facility is highly advanced or in developing countries with little internet access. Investigations in countries that fall in between these two extremes are rare. This study of respondents from higher education institutions and research institutes examines the relationship between collaboration and internet use, as well as productivity and internet use in the South African scientific system which has become a strong contributor to science in Africa.     

Home and school influences on the behavioral and academic outcomes of low-income children of color

Framed within contextual systems model, this study examines how home and school operate together to shape behavioral and academic outcomes for 544 low-income African American (56%) and Latino/a (44%) elementary school-aged children (mean age?=?7.88 years, SD?=?1.46, 50% male). Using data from Welfare, Children, & Families Study: A Three City Study and multiple group path analysis, we found that for children in kindergarten through third grade, the adequacy of the home resources was positively related to applied problem scores (e.g. math literacy) and negatively associated with externalizing behavior. For fourth- to sixth-graders, the adequacy of classroom resources was negatively associated with applied problem scores. For both age groups positive teacher–child relational quality was also a positive predictor of externalizing behavior. Results revealed that barriers to parental involvement in school were a negative predictor of applied problem scores for low-income children in early and later elementary school. Implications for policy and practice aimed at strengthening opportunities for children and families from marginalized communities are discussed.     

巴迪欧的元政治学--一种反政治哲学的姿态

当代政治哲学陷入了判断者和行动者的两难困境，其原因在于：一是它通过商谈的方式达成共识；二是它在政治哲学评判时所遵循的伦理标准和共通感。元政治学解决了政治哲学的这一困境，它独辟蹊径地以数学本体论为奠基，实现了将政治作为真之政治的目的。而实现真之政治需要做的是协调政治与国家、政治与主体和政治与哲学的关系，最终清除一种政治的幻想，走出一条通向真之政治的可能性道路。     

婚姻市场、农业剩余与光棍分布--一个理解农村光棍问题的中观机制

在婚姻市场渗透下，中西部农村家庭继替具有市场参与性特征：婚姻市场竞争过程形塑出以竞争力为指标的婚姻梯队序列，在优势梯队实现的家庭继替具有向上社会流动的特征，梯队末端则呈现为底层沦陷；农村男性青年在婚姻梯队序列所处的位置取决于其家庭的资源积聚方式、能力和分配方式。调查发现末端梯队集中分布于农业剩余稀薄村庄，其内在机理是农业剩余稀薄通过形塑家庭劳动力的不合理配置与以年轻人为主体的资源积聚方式和向家庭日常生活基本需要进行倾斜的资源分配方式削弱了男性青年的婚姻市场竞争力，其现象表征是扎堆分布的光棍。     

陈柱散文研究的理论体系构建及文学史价值

民国时期的国学大家陈柱，一生著述甚丰。他的散文研究述及中国散文史、散文分类、散文创作论等诸多方面，形成了自己独具特色的散文理论体系。出于矫治时弊的意图，陈柱以“学术”内质和“文学”外式的体用关系构建了散文理论的基石；以此为基础，他尝试以“文言”和“质言”划分散文体类，探索归纳出中国散文的内部类型；与他的散文理论相呼应，陈柱将六经视为后世文学的源头，提出“体尊质衰”的散文史观。他将后世散文之弊归因于“尊体”的结果，主张以先秦文学为散文范本。陈柱以融汇经史子集的广阔视野来审视中国散文的历史发展规律，推动了后来的中国散文研究和散文史书写。     

Moving Forward or Taking a Stand? Discourses Surrounding the Politics of Wisconsin High-speed Rail

The 2010 launch of a national high-speed rail (HSR) initiative became heavily politicized in some parts of the U.S. Research on HSR, however, has predominantly focused on quantitative variables at the national scale, while the fraught sub-national politics of HSR have been mostly overlooked. Using discourse theory, I explore the politics of Wisconsin HSR, arguing that HSR figured heavily in a larger state-based political struggle over conflicting spatial visions of how Wisconsin ‘ought’ to be. This research highlights the significance of spatiotemporally contingent meanings and the scale of analysis in politics of mobility research.     

Imagining mobility: the prospective cognition question in migration research

Most migration research is focused on migrant experiences after mobility and settlement. We argue that empirical researchers would benefit from studying how cognitive migration, the narrative imagining of oneself inhabiting a foreign destination prior to the actual physical move, influences migration behaviour. This article notes a gap in our current understanding of the process by which individuals decide to cross international borders and offers an agenda for remedying this. The interdisciplinarity of migration research has not fully extended to social psychology or cognitive social sciences, where a dynamic research agenda has examined human decision-making processes, including prospection and the connections between culture and cognition. The study of socio-cognitive processes in migration decision-making has been largely overlooked because of the after-the-fact nature of data collection and analysis rather than an aversion to these approaches per se. We highlight a number of strategic findings from this diverse field, provide examples of migration scholarship that has benefited from these insights, and raise questions about the sides of migration process that have received insufficient attention. A more nuanced understanding of prospective thinking—imagining potential futures—can shed light on the classic puzzle of why some people move while others in comparable situations do not.     

政府支出对医疗服务健康公平影响的比较和启示

医疗服务公平和人民的健康是各国卫生系统向其国家居民提供医疗服务所应实现的两个重要目标。但以英美日为例的发达国家根据世界卫生统计年鉴中的医疗服务公平性排名确有明显差距，因此，高收入和高政府医疗卫生支出与医疗卫生服务公平和健康公平性并没有必然关系。本文通过比较分析美日英国的政府间医疗卫生支出责任划分的结构发现高政府医疗卫生支出比例是提高医疗服务筹资公平性的前提，中央承担社会医疗保险责任是实现医疗服务筹资公平性的保证，政府特别是中央政府出资的长期护理有助于提高国民健康水平，地方政府的参与更有助于提高一国医疗系统机构数量特别是医院的数量。
