基于三维虚拟环境的机器人运动学分析与轨迹规划

农民工市民化意愿主要包括就业意愿、生活意愿、定居意愿、户籍意愿和身份意愿。农民工人力资本和社会资本对其市民化意愿具有显著影响。包括农民工年龄、健康状况、受教育程度、在职培训、技能水平在内的人力资本,通过就业效应、融合效应、保障效应和学习效应,对农民工市民化产生重要影响;包括农民工社会关系网络广度、网络深度、网络资源三方面内容的社会资本,通过信息效应、信贷效应、心理支持效应等多种机制对农民工市民化产生重要影响。需要通过提高技能水平、加强在职培训、提高健康水平、提高受教育程度、优化年龄结构等措施,提高农民工人力资本存量;通过增加社会关系网络资源、深化网络深度、扩大网络广度等措施,提高农民工社会资本存量,从而提高农民工市民化意愿。     

农民工养老保险参与决策：一个OLG模型的考察

通过构建一个农民工追求跨期效用最大化的OLG模型,理论分析了均衡条件下农民工收入及风险偏好因素对其养老保险参与决策的影响;基于全国31个省市的调查数据,利用双变量Probit模型实证分析了个人与家庭特征、收入与土地、务工状况与预期等因素对农民工养老保险参与决策的影响。结果表明：务工与务农收入对农民工参与养老保险决策的影响并不显著,而恩格尔系数和非收入性因素却大多显著地影响了农民工的参保决策。为此,一方面,要提高农民工的收入水平、生活宽裕程度和支付能力,使之更有意愿和能力参与养老保险;另一方面,要增强农民工对未来生活确定性的预期和安全感,使之参与养老保险的水平得以提高。     

星星之火，何以燎原——论社会保障国际合作的兴起与发展

由于海外劳工在境外就业期间往往会遭遇社会保障双重缺失、社会保障双重缴费以及社会保障待遇支付障碍等诸多困境,使得西欧国家于20世纪初开始探索开展社会保障国际合作,主要方式是国家之间签署社会保障国际协定,合理地承担和分享海外劳工社会保障的责任与效益。经过一个多世纪的发展,社会保障国际合作开始由探索时期步入成熟时期,不仅在覆盖区域、惠及人群以及主要内容方面实现了由小到大、由少到多和由点到面的发展,而且在合作方式上实现了由双边协定到双边与多边协定并举的发展,进而成为了全球各国维护海外劳工社会保障权益的有效途径。     

Assisting the High Administrative Court in Restricting Too Broad a Concept of Academic Judgment

I have received substantial monetary compensation and a formal apology from my first doctoral school, and a Ph.D. from another university. This essay describes my personal view on discussing the boundaries of academic judgment and research supervision with the ombudsman agency for higher education, and at the High Administrative Court of England and Wales. The Court’s judicial doctrine addresses substantial research accountability matters. It clarifies that although the Court and ombudsman agency must not interfere with academic judgment, not everything done by an academic can be considered as academic judgment. A Ph.D. supervisor can seriously fail to perform his/her duties.     

Danish and Norwegian hospital social workers’ cross-institutional work amidst inter-sectoral restructuring of health and social welfare

Starting in the 2000s, Denmark and Norway have undergone extensive restructuring of their health-related social benefit programmes, including how they are governed. Several reforms have sought to enhance inter-sectoral collaboration. Aiming at ensuring patients’ faster return to work, policy-makers have instituted economic incentives to both individuals and the health and welfare organisations who handle them. Through an institutional logics approach, this paper explores how hospital social workers in these countries are experiencing these changes. The ‘social’ part of post-treatment care and rehabilitation receives more attention in the Norwegian institutional set-up than in the Danish, and whilst challenges are experienced in both countries, in group interviews Danish social workers in particular express concerns about the implications of the accelerated return-to-work focus. In both countries, they report increasing difficulties in ‘making their way through’ the state-municipal bureaucracy. However, by drawing on the formal health knowledge derived from medical settings and the symbolic capital it bestows on them, they often manage to negotiate the work-and-welfare services, thereby transforming the social context for the patients.

You Catch More Flies With Honey: Sex Work,Violence, and Masculinity on the Streets

Violence among inner‐city men is a pressing social concern, and the central focus of much academic research. Many frame it as a phenomenon that certain men perpetuate—those who inhabit disadvantaged, impoverished communities—and argue it is linked to performances of “street” masculinity. In this article, I examine male street‐based sex workers’ willingness to become embroiled in violent exchanges. In a departure from theoretical predictions, my findings reveal these men expend considerable effort to remain nonviolent with others immersed in the sex trade, a decision based upon their desire for the acquisition of capital as well as their calculation of risks. In doing so, they construct and perform a nuanced version of masculinity, which I call pacifist masculinity. Few studies analyze peaceful and conciliatory interactions among men in these contexts, an absence that only serves to reify assumptions about rampant hostility and aggression. I draw on interviews with 19 men involved in street prostitution in Chicago in 2012. This article contributes to a clearer understanding of male–male violence in high‐risk environments, examines the prominent factors that inform decisions to assault others, and explores how such actions challenge hegemonic masculinity.

A life of fear: Sex workers and the threat of HIV in Uganda

Schoemaker J, Twikirize J. A life of fear: sex workers and the threat of HIV in Uganda The way individuals perceive their risk to certain threats influences their adoption of preventive behaviour. This study explored sex workers' perception of risk of HIV infection within the context of other serious threats. The study was carried out in Kampala, Uganda, using peer ethnography. Sex workers were well aware of their risk of HIV infection but this risk was eclipsed by other more immediate and frightening threats. Sex workers' willingness to gamble with HIV is explained by the fact that their existence is already very dangerous, and taking risks is an inherent part of their trade. Decriminalising sex work could make their lives somewhat safer, motivating them to better protect themselves, but this is unlikely to happen in Uganda. Attempting to enforce some coercive control mechanisms would not work, given the pervasive corruption in law enforcement and the judiciary, the institutions that would be responsible for implementing such control.     

Dealing with context in logic model development: Reflections from a realist evaluation of a community health worker programme in Nigeria

Logic models (LMs) have been used in programme evaluation for over four decades. Current debate questions the ability of logic modelling techniques to incorporate contextual factors into logic models. We share experience of developing a logic model within an ongoing realist evaluation which assesses the extent to which, and under what circumstances a community health workers (CHW) programme promotes access to maternity services in Nigeria. The article contributes to logic modelling debate by: i) reflecting on how other scholars captured context during LM development in theory-driven evaluations; and ii) explaining how we explored context during logic model development for realist evaluation of the CHW programme in Nigeria. Data collection methods that informed our logic model development included documents review, email discussions and teleconferences with programme stakeholders and a technical workshop with researchers to clarify programme goals and untangle relationships among programme elements. One of the most important findings is that, rather than being an end in itself, logic model development is an essential step for identifying initial hypotheses for tentative relevant contexts, mechanisms and outcomes (CMOs) and CMO configurations of how programmes produce change. The logic model also informed development of a methodology handbook that is guiding verification and consolidation of underlying programme theories.
