高速铁路与经济增长的因果关系

针对中国高速铁路供给对经济增长和产业结构的影响,以及产业结构、城镇化率、人口密度如何决定高速铁路供给等问题,对高速铁路与经济增长的即时效应、快速效应和慢速效应机理进行分析。研究认为,从高速铁路对经济增长角度来看,2005~2014年中国省域面板数据实证表明:高速铁路在十年间的即时效应和快速效应不断降低,高速铁路的高时间价值与高出行成本特性主导的慢速效应占据支配地位,导致高速铁路对全国和中部地区经济增长没有显著影响,对东部地区有显著正向影响,对西部地区有显著负向影响,说明总体上高速铁路并不是经济增长的原因;从经济增长对高速铁路角度来看,Logit模型计量经济增长对高速铁路触发的影响表明:经济增长本源性需求内生出对高速铁路的即时效应、快速效应和慢速效应的派生性需求,经济增长以及第三产业、城镇化率、人口密度变量显著决定高速铁路供给。     

Approximations for a fixed sample size selection procedure for negative binomial populations

A large sample approximation of the least favorable configuration for a fixed sample size selection procedure for negative binomial populations is proposed. A normal approximation of the selection procedure is also presented. Optimal sample sizes required to be drawn from each population and the bounds for the sample sizes are tabulated. Sample sizes obtained using the approximate least favorable configuration are compared with those obtained using the exact least favorable configuration. Alternate form of the normal approximation to the probability of correct selection is also presented. The relation between the required sample size and the number of populations involved is studied.     

BECOMING A TECHNOLOGIST Days in a girl's life

Studies of the gender relations of information and communications technologies (ICTs) seldom deal with these relations as experienced in early childhood, except as located in schooling. The construction of identity in relation to technology is negotiated from an early age. In this article a technological strand is identified in childhood using 'experience stories', writing about specific situations or events on a specific theme, with the focus of analysis being on the theme, rather than on the individual. In reflecting on this technological strand of childhood the article tries to make sense of how everyday experiences serve as sites for constituting our relations with ICTs, and more personally, how they constitute relations for a young white working-class girl. This article also hopes to make visible technological acts which are essentialized and/or made invisible in later years. This article draws on a multi-layer definition of technology and uses conceptions of locally situated knowledge and practices to explore how a young girl might develop a familiarity with technology as part of everyday living. Class and race relations as well as gender relations are significant in early conceptions of 'knowing and doing' and later awareness of constructions of technology and technological identities and subjectivities. This article therefore attempts to identify these relations within the experience stories. By applying a concept of technology that encompasses the knowledge, skills and practices in the everyday life of a young girl, the author hopes to contribute to a richer understanding of the gender, class and race relations implicit in what is recognized as technological knowledge and to contribute to a more inclusive understanding of the social relations of ICTs.     

Gender Role Ideology and the Gender Based Differences in Earnings

Much of the research on gender differences in occupational earnings still focuses on human capital and the structure of the labor market. However, these variables rarely explain even half of the gender gap in earnings. Most research has examined the impact of gender role ideology as it impacts occupational choice, which indirectly can impact earnings. Using data from the National Opinion Research Center General Social Surveys, this research focuses on the relationship between attitudes about gender roles and two variables: (a) earnings, and (b) occupational positions held by women and men. Findings show that traditional gender-role ideology contributes to lower observed earnings for both males and females, independent of the influences of human capital characteristics, occupational context, and ascribed characteristics. Results support socialization as a partial explanation for the gender-based earnings differences and suggest that, to the extent that economic rewards are used to assess the value of gender role expectations, traditional gender role attitudes might continue to change and lead to relatively equal earnings among women and men.     

“Like Two Musketeers”: Socialization beliefs about toddler's friendships among Dominican,Mexican, and African American mothers

Parental ethnotheories shape socialization beliefs around childrearing more broadly, and children's friendships more specifically. While prior work has examined aspects of parental socialization of friendships among school-aged children and adolescents, no studies have examined beliefs held around the function of friendships among ethnically diverse mothers of toddlers from low-socioeconomic contexts. Toddlerhood marks a point in development when the concept of “friendship” gains impact and relevance due to leaps in children's social, cognitive, and motor skills, as well as children's increasing access to contexts where they organically encounter peers. Toddlerhood is also a time when caregivers may initially consider the influence of peers on their children, beliefs that could eventually guide and shift how they navigate socialization practices around friendship. In the present study, we document U.S. Dominican American, African American, and Mexican American mothers’ socialization beliefs around functions of friendship for their 2-year-old children. We found that mothers emphasized a variety of friendship functions, including learning of social skills and morality, and communicating and experiencing emotions. A majority of mothers viewed their children's friendships as unidirectional, and framed their children as undiscerning in their engagement with social information from peers. Findings are discussed in relation to mothers’ orientation to children and “childhood” via cultural and developmental beliefs.     

The Asylum‐Integration Paradox: Comparing Asylum Support Systems and Refugee Integration in The Netherlands and the UK

This article explores the impact of asylum support systems on refugee integration focusing on the UK and the Netherlands. Both have adopted deterrent approaches to asylum support. The Dutch favour the use of asylum accommodation centres, segregating asylum seekers from the general population. The UK disperses asylum seekers to housing within deprived areas, embedding them within communities. Both countries have been criticized for these practices, which are viewed as potentially anti‐integrative: something of a paradox given that both promote the importance of refugee integration. We analyse national refugee integration surveys in both countries and provide original empirical evidence of negative associations between asylum support systems and refugees’ health, which differ in relation to mental and physical health. The integration and asylum policy implications of these findings are discussed.     

Poverty,Place, and Coal Employment across Appalachia and the United States in a New Economic Era

The impacts of employment in the coal industry remain controversial. Few studies have investigated these impacts over the decade of the great recession and in light of the nation's changing energy economy. We bring together two long‐standing rural sociological traditions to address debates framed at the national level and for Appalachian communities facing the throes of transition from the coal industry. Building from rural sociology's “poverty and place” tradition and from natural resources sociology, we examine the relationship between coal employment and communities’ economic well‐being as indicated by poverty, household income, and unemployment. The study spans U.S. and Appalachian counties from 1990 to 2010. U.S. counties with greater coal employment in 1990 had lower income and higher poverty in 2000. Overall, however, coal employment's effect is mixed in the 1990–2000 decade. By contrast, for the recent 2000–2010 decade, coal employment is positively associated with indicators of well‐being. In Appalachia, fewer employment alternatives outside mining are related to higher well‐being. Our findings extend the poverty and place literature and the natural resources literature and underscore why a just transition away from coal should focus on moving communities toward sectors offering better future livelihoods.     

Gender Differences in Emotion Expression in Low-Income Adolescents Under Stress

Gender roles in mainstream US culture suggest that girls express more happiness, sadness, anxiety, and shame/embarrassment than boys, while boys express more anger and externalizing emotions, such as contempt. However, gender roles and emotion expression may be different in low-income and ethnically diverse families, as children and parents are often faced with greater environmental stressors and may have different gender expectations. This study examined gender differences in emotion expression in low-income adolescents, an understudied population. One hundred and seventy nine adolescents (aged 14–17) participated in the Trier Social Stress Test (TSST). Trained coders rated adolescents’ expressions of happiness, sadness, anxiety, shame/embarrassment, anger, and contempt during the TSST using a micro-analytic coding system. Analyses showed that, consistent with gender roles, girls expressed higher levels of happiness and shame than boys; however, contrary to traditional gender roles, girls showed higher levels of contempt than boys. Also, in contrast to cultural stereotypes, there were no differences in anger between boys and girls. Findings suggest gender-role inconsistent displays of externalizing emotions in low-income adolescents under acute stress, and may reflect different emotion socialization experiences in this group.     

Service user involvement in Swedish mental health and social care: an analysis of ideological dilemmas and subject positions in a collaboration context

Service user involvement is steadily on the rise, bringing questions of tokenism and power imbalance. This article studies service user organisation representatives (URs) and human service organisation representatives (HSORs) in mental health and social care strategic collaboration councils through qualitative interviews and participant observations. Talk on service user involvement through UR is studied through the discourse analytical concepts of ideological dilemmas and subject positions. The participants' constructions, actions, and rhetoric therein are considered. Findings show participants' oscillation between standpoints within two main themes: the ideal vs. the inadequate UR and balancing power positions. The first theme discusses the missing perspective brought by UR narrations in terms of expected conduct and awareness of organisational conditions. This also concerns service users' positions as being simultaneously dependent and independent. The second theme concerns the implicit UR influence and the explicit HSOR influence. User involvement through URs is construed as a needed narration told by citizens with rights and responsibilities, while conditioned, as the UR is a layperson with mental health problems. The actions accompanying such constructions cause HSORs to balance between paternalism and professionalism and URs between adaptation and using their voice. In this, the URs have a stronger influence than acknowledged.
