重楼总皂苷对人胃癌细胞SGC-7901 增殖、迁移和侵袭能力的影响

目的 探讨重楼总皂苷（Rhizoma Paridis total saponin,RPTS)在体外对人胃癌细胞SGC-7901侵袭转移能力的影响。方法 取对数生长期的SGC-7901细胞,用不同浓度RPTS(2.5、5、10、20、40 μg/mL)处理24 h,四甲基偶氮唑蓝（methyl thiazolyl tetrazolium, MTT）法观察RPTS对细胞增殖能力的影响;采用细胞划痕实验、Matrigel transwell小室侵袭实验检测SGC-7901细胞的迁移和侵袭能力。结果 MTT法检测表明RPTS（10、20、40 μg/mL）可明显抑制SGC-7901细胞的增殖能力（P＜0.05）;细胞划痕实验、Matrigel transwell小室侵袭实验结果表明RPTS(2.5、5、10 μg/mL)处理过的SGC-7901细胞,迁移能力和侵袭能力降低（P＜0.05）。结论 RPTS具有抑制人胃癌细胞SGC-7901细胞增殖、迁移和侵袭的能力。     

From Exclusion to Resistance: Migrant Domestic Workers and the Evolution of Agency in Lebanon

In addition to hosting a large population of refugees and displaced persons, Lebanon is home to an estimated 200,000 to 300,000 migrant domestic workers. Under Lebanese law, domestic workers fall under the kafala, or sponsorship, system. Existing literature has focused on the legality of the kafala system and the ensuing human rights violations resulting from workers' exclusion from Lebanese labor law. Based on fieldwork conducted in 2016, this article argues that migrant domestic workers in Lebanon have defied their spatial, social, and legal exclusion by organizing collective resistance, triggered in part by the July 2006 Israel-Lebanon war.     

Migration management for the benefit of whom? Interrogating the work of the International Organization for Migration

This paper examines the relationship between the nation-state and migration through the activities of the International Organization for Migration (IOM). The IOM operates at the intersection of nation-states, international human rights regimes, and neo-liberal governance. We find that the IOM enforces the exclusions of asylum seekers and maintains the central role of nation-states in ordering global flows of migration. In addition, we argue that the IOM acts on behalf of nation-states by using the language of international human rights, as though working in the interests of migrants and refugees. In providing a geographic appraisal of the IOM alongside its image and presentation with an analysis of its activities on voluntary returns, we address the new spaces of ‘networked’ governance that control and order migratory flows in the interests of nation-states.     

Quelles mobilités pour quelles ressources?

In West Africa, where the available natural and financial resources are not always sufficient to support a family for a whole year, mobility has become a strategy for accessing the resources of the region as a whole. Daily life is based on a mixed sedentary and mobile logic which responds to opportunities at greater or lesser distances, for longer or shorter periods of time, and with greater or lesser regularity of movement, and which enables survival or a better livelihood to be secured. Mobility requires mobilisation – of social networks, individual capacities and sociabilities, elements we can also refer to as resources, only this time social resources. This article explores the notion of resources and its connotations to show how populations in the West African Sahelian space seek a balance of survival and livelihood through mobility.     

The Social Sciences and a New Administration

The policy issues confronting the new administration in 2009 can benefit greatly from the results of social, behavioral, and economic sciences research. Climate change, energy, human capital, social, capital, migration, public health, fairness, new technologies, and foreign and defense policy are all issues that the research has addressed. The participation of social scientists in the policy process will enhance the contributions of the research.

英属时期印度人移民马来亚的原因及其影响研究

英属时期,印度人大规模移民马来亚。析其原因,当时西方资本主义殖民经济的蓬勃发展和奴隶制的废除是推动印度人大规模移民马来亚的国际背景;移民输出地印度和输入地马来亚当时的政治、经济、社会及人口状况等因素则是推动印度人大规模移民的地区背景。大规模外来移民的结果不仅改变了马来半岛固有的民族成分和社会结构,也为日后马来(西)亚的族群矛盾和冲突埋下了伏笔。     

Retired EU migrants,healthcare rights and European social citizenship

Drawing on a set of 210 qualitative interviews conducted in six European countries, this paper investigates the citizenship status and experiences of retired EU migrants at both national and European levels. The paper focuses upon the experiences of two types of respondents: 'Retired Migrants' (retired nationals of one EU country who moved on retirement and reside in another EU host state) and 'Returnees', that is, those migrants who have chosen to return to their country of origin after a period of residence abroad. In particular, this paper will attempt to explore three issues: (a) The extent to which retired migrants have access to, and make use of, the public healthcare systems of the countries in which they reside. (b) Retired migrants' perceptions and experiences of those systems. (c)Whether or not a lack of access to and/or the quality of public healthcare is an important determinant of return migration decisions, i.e. moves back to the country of origin. By focusing on healthcare the paper combines an analysis of the formal welfare rights available to EU citizens who migrate on retirement (both in terms of their EU rights and their status in the receiving and exporting countries) with qualitative evidence that documents the substantive reality of such rights.     

“八零前”与“八零后”流动人口家庭迁移行为比较研究

本文使用"2010年下半年全国流动人口动态监测"数据,按照出生年份划分流动人口代际群体,在经典迁移理论和新迁移经济学的框架下比较分析"八零前"与"八零后"流动人口家庭迁移行为。研究发现,流动人口在受教育程度、职业身份等方面存在显著代际差异,并对家庭迁移产生显著影响。而在居住时间、迁入地家庭总收入、移民汇款等方面不存在代际显著差异,对家庭迁移的影响存在代际一致性。     

Switzerland – Really Europe's Heart of Darkness?

Immigration is a prominent and contested global topic of contemporary politics. Several recent popular votes targeting migration such as the minaret initiative, the automatic deportation initiative, and most recently the vote on “mass immigration”, evoke however the impression that Switzerland sets particularly harsh standards in migration policy. Based on historical evidence on Swiss migration policy making and comparative analyses on current cantonal integration policy outputs, I argue that ‐ while far from being a new phenomenon ‐ immigrant scepticism has become a more relevant factor of Swiss migration policy making than ever. Yet, immigration and immigrant scepticism do not only challenge direct democratic Switzerland, but all destination countries of immigration.     

Co-producing a post-trafficking agenda: collaborating on transforming citizenship in Nepal

This article discusses how a new agenda on post-trafficking is gaining momentum through academic and activist anti-trafficking collaborations focused on co-producing knowledge with women who have returned from trafficking situations. Co-production of this nature is important as the issues raised by post-trafficking scenarios are largely ignored in anti-trafficking strategies, and the stigmatisation and poverty which women in these circumstances encounter means they rarely have a voice in policy-making. Drawing on research in Nepal, we present four types of co-produced data around transforming citizenship post-trafficking, and reflect on the strategies for generating and using them for advocacy purposes.
