蒙古——突厥史诗英雄与骏马同时诞生母题的比较研究

蒙古—突厥史诗中的英雄及其骏马有着不同寻常的关系。蒙古—突厥史诗中英雄及其骏马同时诞生母题与英雄的骏马将自己的主人拖出地面的再生母题之间的结构关系。蒙古—突厥史诗中英雄被敌人抛入地下之后英雄的骏马用尾巴把主人从地下拖出地面的母题与英雄的骏马先于英雄的诞生而出生的特异诞生母题之间在结构上存在着一种置换关系。两者都是英雄的诞生仪式。     

基层政府的政策变通逻辑 ——以H县“不再生育合同”为个案

本文通过H县“不再生育合同”的个案分析基层政府在社会治理中的政策变通逻辑。政策变通不是对政策目标的背离,而是为了政策具有可行性。政策变通是社会治理中政策制定上的普遍主义和政策执行上的特殊主义相结合的体现。基层政府政策变通的初始逻辑是为了实现国家的政策目标,政策变通范围的扩散逻辑是为了尊重政策对象的习惯,基层政府不断扩大政策变通适用对象范围是出于自利动机以筹集工作经费,除了以上三种逻辑外,政策变通延续还有一个重要逻辑,即基层政府面临对象要求兑现知情选择法定权利的压力。这些多元复合逻辑驱动的政策变通不仅没有偏离政策目标,反而使取得良好的政策预期效果。     

Designing out vulnerability, building in respect: violence, safety and sex work policy

One recent finding about the prostitution market is the differences in the extent and nature of violence experienced between women who work on the street and those who work from indoor sex work venues. This paper brings together extensive qualitative fieldwork from two cities in the UK to unpack the intricacies in relation to violence and safety for indoor workers. Firstly, we document the types of violence women experience in indoor venues noting how the vulnerabilities surrounding work-based hazards are dependent on the environment in which sex is sold. Secondly, we highlight the protection strategies that indoor workers and management develop to maintain safety and order in the establishment. Thirdly, we use these empirical findings to suggest that violence should be a high priority on the policy agenda. Here we contend that the organizational and cultural conditions that seem to offer some protection from violence in indoor settings could be useful for informing the management of street sex work. Finally, drawing on the crime prevention literature, we argue that it is possible to go a considerable way to designing out vulnerability in sex work, but not only through physical and organizational change but building in respect for sex workers rights by developing policies that promote the employment/human rights and citizenship for sex workers. This argument is made in light of the Coordinated Prostitution Strategy.     

中国省际人口流动与 人力资本流动差异性分析

人力资本流动与人口流动相关却不相同,本文采用2010-2016年全国流动人口动态监测数据,从流动方向和流动强度两方面对我国省际人口流动引致的人力资本流动现象加以研究。结果表明从流动方向分析,各省人口净流动方向基本呈现时间一致性并且流入流出区域具有稳定性。在调查期间人口净流出省份为16个,人口净流入省份为15个,没有明显变化。人力资本净流向与人口净流向完全一致,但省际人口净流向与高级人力资本净流向并不完全一致,山西、广西、重庆等省市的高级人力资本净流向始终与总人力资本净流向相反。本文采用流出流入比率和迁移选择中心两种指标测算人力资本流动强度,结果基本一致。人力资本流动中心与人口流动中心分布均较为固定。2010年人力资本流动强度最大的省份在2016年的流动强度也更强,流动强度在省际呈现惯性和马太效应。人力资本流入最强地区包括北京、天津、上海三个直辖市,人力资本流出最强省份始终包括安徽、四川、河南等省份。以人力资本流出弹性衡量人力资本流出强度与人口流出强度的相对强弱,东部地区、东北地区省份人力资本的流出强度始终大于人口流出强度,西部地区省份差异较大。考虑各省近五年经济增长状况,人口流动或者人力资本流动对经济增长的影响是非线性的。     

Status and competitive choice

In this paper, we extend the logic of existing sociological theory on status to explain how status processes can inform selection in competitive choice situations. We argue that in the absence of knowledge about the specific abilities of others and assuming a desire to win, when given the opportunity to “pick their battles,” people will draw on overt status differences as a basis for selecting a competitor from a pool of possible competitors. Results from three studies indicate that, as predicted, status differences affect competitor selection, with individuals choosing to compete against those who are relatively lower status based on diffuse characteristics. Moreover, consistent with expectation state theories, results from two studies show that the expectations that people form for their potential competitors based on status differences mediate this relationship. We conclude by discussing the implications of this research.     

Generalized estimator of population mean by using conventional and non-conventional measures in the presence of measurement errors

In survey research, it is assumed that reported response by the individual is correct. However, given the issues of prestige bias, self-respect, respondent's reported data often produces estimated values which are highly deviated from the true values. This causes measurement error (ME) to be present in the sample estimates. In this article, the estimation of population mean in the presence of measurement error using information on a single auxiliary variable is studied. A generalized estimator of population mean is proposed. The class of estimators is obtained by using some conventional and non-conventional measures. Simulation and numerical study is also conducted to assess the performance of estimators in the presence and absence of measurement error.     

Risking safety and rights: online sex work,crimes and ‘blended safety repertoires’

It has been well established that those working in the sex industry are at various risks of violence and crime depending on where they sell sex and the environments in which they work. What sociological research has failed to address is how crime and safety have been affected by the dynamic changing nature of sex work given the dominance of the internet and digital technologies, including the development of new markets such as webcamming. This paper reports the most comprehensive findings on the internet‐based sex market in the UK demonstrating types of crimes experienced by internet‐based sex workers and the strategies of risk management that sex workers adopt, building on our article in the British Journal of Sociology in 2007. We present the concept of ‘blended safety repertoires’ to explain how sex workers, particularly independent escorts, are using a range of traditional techniques alongside digitally enabled strategies to keep themselves safe. We contribute a deeper understanding of why sex workers who work indoors rarely report crimes to the police, reflecting the dilemmas experienced. Our findings highlight how legal and policy changes which seek to ban online adult services advertising and sex work related content within online spaces would have direct impact on the safety strategies online sex workers employ and would further undermine their safety. These findings occur in a context where aspects of sex work are quasi‐criminalized through the brothel keeping legislation. We conclude that the legal and policy failure to recognize sex work as a form of employment, contributes to the stigmatization of sex work and prevents individuals working together. Current UK policy disallows a framework for employment laws and health and safety standards to regulate sex work, leaving sex workers in the shadow economy, their safety at risk in a quasi‐legal system. In light of the strong evidence that the internet makes sex work safer, we argue that decriminalisation as a rights based model of regulation is most appropriate.     

Precarious intimacies – Europeanised border regime and migrant sex work

This article examines the meaning of borders – the spaces where immigration policies and restrictions are materially condensed – in the lives of migrant sex workers. I provide a theoretical and conceptual framework to discuss the role of borders in creating living and working conditions for sex workers within the European border regime. This regime both restricts and enables a structural background for migrant sex work. I argue that sex work scholars should pay closer attention to the heterogeneity of non-citizenship and the effects of different immigration statuses on the working conditions and forms of intimacies migrants create. Borders need to be viewed as institutions that produce social relations. I categorise these relations as precarious intimacies to describe the ways in which intimacy, commerce and borders often intertwine in the lives of migrants engaged in commercial sex work. The article draws upon 18-month ethnographic fieldwork among and interviews with migrant sex workers in Finland.
