流动人口的社会阶层、社会流动与未婚先孕——以上海市为例

采用二元逻辑斯蒂回归模型,从社会阶层与社会流动的视角对影响流动人口未婚先孕的因素进行分析.关于社会阶层的研究结果显示,育龄妇女的受教育程度与月均收入水平两因素的影响结果显著,受教育程度越高未婚先孕的比例越低,收入越高未婚先孕的比例越低.育龄妇女的户口对未婚先孕不产生显著性影响;关于社会流动的研究结果显示,育龄妇女婚姻的教育匹配与户口匹配对未婚先孕有着显著性影响,教育匹配的上向流动增加未婚先孕的比例,下向流动降低未婚先孕的比例.但户口匹配却显示出上向流动降低未婚先孕的比例,下向流动增加未婚先孕的比例.     

Household Registration Reform,Labor Mobility and Optimization of the Urban Hierarchy

A rational hierarchy of rank-size distribution is indispensable for optimizing the urban hierarchy. On the basis of the number of permanent urban residents, using rank-size rule testing and core density estimation within the framework of spatial economics, we set up a labor force location choice model and conducted quantitative simulations. Our findings show that the structure of China’s urban hierarchy differs from the pyramid structure of Zipf’s Law, and the household registration system impedes the free movement of labor and makes the size distribution of cities deviate from Pareto optimality. Household registration (hukou) reform will be conducive to the optimization of the urban hierarchy. Optimizing the urban hierarchy should become a consistent objective in today’s development of new-type urbanization, city clusters and metropolitan areas.     

What’s India’s Beef with Meat? Hindu Orthopraxis and Food Transition in India Since the 1980s

Does development affect food practices? The nutrition transition model correlates positively meat consumption levels with gross domestic product per capita, except in India. In this article, I analyze food diets in this country since the 1980s by mapping out households’ practices in animal product consumption depending on their social positions. Applying multiple factor analysis on the Consumer Expenditures data of the National Sample Survey Office, I produce a relational model of food diet segmentation to overcome the dead ends of the nutrition transition model. Two structural dimensions are highlighted. The first one differentiates beef and nonbeef meat diets and relates to the symbolic capital of caste and religion. The second one opposes diets including animal products and without, depending on the amount of economic capital. The concept of temporal homology is introduced to show that the social structure remains stable over time. This denotes the importance of sociocultural norms in food practices rather than their weakening due to “modernization” and shows how these norms are key to understand food transitions beyond linear expectations drawn from economic development.     

Ten years of Boko Haram: how transportation drives Africa’s deadliest insurgency

ABSTRACT

This article challenges the ways in which much scholarship on terrorism and insurgencies have been ‘a-mobile.’ It addresses this problem by drawing on the ‘new mobilities paradigm’ to explore analytically how the decade-long Boko Haram insurgency in north-eastern Nigeria have developed around the system of automobility and have simultaneously been transformed by it. The analysis extends to the impact of the violent insurgency and state regulation on populations whose livelihoods are rooted in mobility. Foregrounding automobility as a lethal weapon, an instrument of power, the article recasts the evolution and mutation of Boko Haram in light of how the group weaponizes transportation/mobility, and how it interacts with differently and differentially mobile others. This article should be seen as a first attempt to insert the subject of (auto)mobility into the rapidly growing literature on Boko Haram, contributing to our meagre understanding of how movement and stasis influences the group’s tactics and choice of targets. It brings together qualitative data collected through in-depth interviews, focus group discussions, media reports, and hours of observations at roadblocks and control posts operated by a local security assemblage of police officers, paramilitaries, and soldiers.     

从“官吏分途”到“层级分流”:帝国逻辑下的中国官僚人事制度

魏晋南北朝以来的“官吏分途”是中国官僚体制的重大制度变迁,本文从这一角度出发,审视当代中国官员的空间流动状况,提出以“官吏相对谱系”为特点的“层级分流”模式。文章从周雪光的“帝国逻辑”分析框架出发,借用史学研究和社会科学理论来认识和解释人事制度安排与帝国治理逻辑之间的关系。文章认为,从“官吏分途”到“层级分流”,这一人事制度造成了官僚体制的二元结构及其迥然不同的职业生涯、激励设置和利益群体,为中国官僚体制的运作打上了鲜明烙印。本文充实和扩展了“帝国逻辑”的理论思路。     

Students’ narratives of the future: Imagined mobilities as forms of youth agency?

In the context of the ‘iFuture’ research project, 341 18-year-old Sardinian students were asked to write an essay in which they imagined themselves at 90 and described what their futures (in the past) would look like. Such data allow us to investigate the notion of agency. Agency and the future are deeply intertwined: agency involves the idea of projection and implies anticipation; the ‘desired’ futures have an impact on the ways in which youth act in the world today. We focus on the analysis of one of the emerging findings, which expresses an interesting configuration of youth agency, namely the imagination of youth mobility. This finding expresses the desire to put some projects into place, yet it concurrently implies that youth believe that these projects are impossible to achieve in the current context. After offering an overview of imagined destinations, we identify two ways in which imagined mobility emerges from the rich material collected: (a) mobility as an entry ticket, to bypass the uncertainty associated with crude reality and (b) mobility as an occasion for self-experimentation and self-growth. We conclude by discussing in what ways these forms of imagined future mobilities may be seen as youth agency.     

A Year Then Forever: Personal Resolution Making and the Temporal Bridge of the Near Future

Based on in-depth interviews and drawing exercises with 25 resolution makers, this paper explores the use of time in structuring and enacting improvement projects of the self. Resolutions are intentional, identity-laden moments when people bring the future into the present. They provide a window into the identity work of the “near future”—an underresearched but fascinating site where individuals transition between what they see as an immediate, controllable future to a more distant one that is less certain. In attempt to mitigate the emotionally and cognitively daunting prospects of the distant future, resolution makers enlist time as a form of capital, constructing the “temporal bridge” of the near future by engaging in three interrelated processes: structuring and remembering, being flexible, and maintaining optimism.     

Class,place and mobility beyond the global city: stigmatisation and the cosmopolitanisation of the local

ABSTRACT

This paper draws on a multi-sited qualitative study of youth in regional Australia to explore the contemporary relationship between class, place attachment, and the imperative towards mobility and cosmopolitanism. The paper shows how local classed identities shape how young people situate themselves and their localities in relation to the rest of the world, and how experiences of mobility produce classed attachments to place. Here, place is made meaningful within the broader cultural politics of inequality in neoliberalism, in which the moral denigration of figures of the working class come to stand for the disadvantage currently associated with regional places. However local classed histories offer some young people the capacity for resistance, whilst others are unable to reframe their localities in positive terms. Moreover, whilst cosmopolitanism is a mode of classed distinction across the two research sites, this can be enacted either through practices of mobility, or through the repositioning of the local in cosmopolitan terms through the identity practices of middle-class youth. The paper therefore reveals new ways in which local social and economic histories offer young people different ways in which to relate to notions of mobility as well as to reconstruct the meaning of their home.     

How do new members affect the relationship between principal investigator’s network position and academic output of granted funds?

The paper focuses on how to improve academic output of a granted fund when the adding of new members changes principal investigator’s network position. This objective is refined by exploring how new members affect the relationship between principal investigator’s network position and the academic output of granted funds, and whether this effect is similar in high-output and low-output collaboration networks. New members are divided into two groups, namely, international collaboration and inbound mobility. Using negative binomial regression on research funds supported by the National Natural Science Foundation of China, the results indicate that new members indeed have moderating effects on the relationship between principal investigator’s network position and the academic output of granted funds. Moreover, we find that this moderating effect in high-output collaboration networks is larger than that in low-output collaboration networks. Our findings provide practical implications for the decision makers to design funding planning and for the principal investigators to improve academic output.     

Hand-Hygiene Mitigation Strategies Against Global Disease Spreading through the Air Transportation Network

The risk for a global transmission of flu-type viruses is strengthened by the physical contact between humans and accelerated through individual mobility patterns. The Air Transportation System plays a critical role in such transmissions because it is responsible for fast and long-range human travel, while its building components—the airports—are crowded, confined areas with usually poor hygiene. Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) consider hand hygiene as the most efficient and cost-effective way to limit disease propagation. Results from clinical studies reveal the effect of hand washing on individual transmissibility of infectious diseases. However, its potential as a mitigation strategy against the global risk for a pandemic has not been fully explored. Here, we use epidemiological modeling and data-driven simulations to elucidate the role of individual engagement with hand hygiene inside airports in conjunction with human travel on the global spread of epidemics. We find that, by increasing travelers engagement with hand hygiene at all airports, a potential pandemic can be inhibited by 24% to 69%. In addition, we identify 10 airports at the core of a cost-optimal deployment of the hand-washing mitigation strategy. Increasing hand-washing rate at only those 10 influential locations, the risk of a pandemic could potentially drop by up to 37%. Our results provide evidence for the effectiveness of hand hygiene in airports on the global spread of infections that could shape the way public-health policy is implemented with respect to the overall objective of mitigating potential population health crises.
