也论迁徙自由的宪法回归

迁徙自由具有基本人权性质,是我国社会主义市场经济体制建立的一个重要条件,也是解决其它社会问题的关键因素,理应入宪。迁徙自由在实现途径上权利赋予与制度保障应衔接进行。     

Land Ownership as a Determinant of Temporary Migration in Nang Rong, Thailand

In this study I consider landownership as a determinant of temporary migrationin a rural area of Thailand. Previous researchon rural areas in developing countries hasfocused on the use of migration to diversifyhousehold incomes across economic sectors andacross geographic areas. I combine thisliterature with economic theories of migrationto understand the effect of land ownership ontemporary migration of household members inNang Rong, Thailand. I estimate regressionmodels predicting the probability of ahousehold having any temporary migrants, andpredicting the number of male or femaletemporary migrants in the household. I findthat households with smaller landholdings arediversifying through migration in order tosupplement rural income, while households withlarger landholdings are diversifying in orderto overcome the absence of accessible credit inthe village.     

Economic Determinants of Net International Migration in Western Europe

This paper aims to estimate theinfluence of economic determinants on netinternational migration in Western Europe inthe period 1960–1998. Net migration rates(i.e., population growth minus natural increase,divided by the midyear population) constitutethe dependent variable. The economicdeterminants used in this study are GDP percapita, unemployment, and average educationallevel (amount of human capital) of thepopulation. Time series regression models havebeen used in country-specific analyses. Inaddition, a pooled cross-sectional time seriesanalysis has been made. The analyses suggestthat GDP per capita has a positive effect andunemployment a negative effect on a country'snet international migration.     

State‐led transnationalism and migration: reaching out to the Argentine community in Spain

Abstract This article focuses on when and how states develop transnational policies. It presents a case study of a relatively small emigrant community, whose departure was not simply caused by poverty or crisis, but most recently by an economic and political debacle that questioned people's values and expectations. I focus on the state side of the equation and identify a shift in Argentina's policy after 2003, though also show how such policies came out of a long history of state intervention in population and migration and are now related to human rights concerns and the unfinished process of democratic consolidation. I argue that the state initiates political transnationalism, not migrants, and highlight the importance of some relatively unexplored factors in the understanding of the motivation, intensity and impact of the state's involvement, such as the characteristics of the emigrant community, the existence of specific political projects, the role of some domestic actors and processes, and the nature of international agreements.     

国际移民学研究:范畴、框架及意义

国际移民学探索的直接目标,是在合理解读移民行为的基础上,推动移民政策的合法制定,进而达到移民个人或群体在大社会中的和谐生存与发展。国际移民学探求的最终目标,是全球资源的合理有效共享,全球人的和平共处,共赢共荣;其最基本问题则可以归结为:何时、何人、为何、如何跨国迁移?跨国迁移对迁移者个人、家庭及相关群体、地区、国家乃至整个世界可能产生什么影响?国际移民学涉及的范围相当广泛,需要建立一个跨学科的、综合性的分析框架。     

20世纪美国黑人大迁徙与南部三农问题之关系

南北战争后,美国南部长期面临农业生产方式落后、农民贫困、农村社会发展缓慢等三农问题。上述问题与南部的种族问题相互交织,加剧了南部社会的落后与黑暗。这其中,南部黑人受害最为深重,他们被迫大规模迁徙到美国其他地区。20世纪美国有两次黑人大迁徙的高潮,到20世纪70年代有600多万南部黑人迁徙。美国南部的三农问题是黑人大迁徙的经济原因,但黑人大迁徙又反过来推动了三农问题的解决,由此可见迁徙自由对于解决三农问题的重要意义。     

就近半城市化与去城市两级分化

农民以家庭为单位普遍选择的就近半城市化路径中,人口迁徙具有可逆性：一是从城市回流到农村的可逆性,二是从大城市回流到中小城市的可逆性。这两种可逆性勾勒着我国城市化进程中的“去城市两极分化”机制：类贫民窟作为物理载体仍然会在城市化的过程中存在,但在可逆过程中,它并不会形成一个刚性的城市社会贫民阶层,进而这种可逆性成为城市社会两极分化结构中的弹性要素;特大城市也会产生,但在可逆的过程中,作为纯资源接受者的中小城市将获得人口集聚和经济发展的契机,从而这种可逆性也构成了城市体系两极分化结构中的弹性要素。     

Assessing Risk‐Based Upper Limits of Melamine Migration from Food Containers

Melamine contamination of food has become a major food safety issue because of incidents of infant disease caused by exposure to this chemical. This study was aimed at establishing a safety limit in Taiwan for the degree of melamine migration from food containers. Health risk assessment was performed for three exposure groups (preschool children, individuals who dine out, and elderly residents of nursing homes). Selected values of tolerable daily intake (TDI) for melamine were used to calculate the reference migration concentration limit (RMCL) or reference specific migration limit (RSML) for melamine food containers. The only existing values of these limits for international standards today are 1.2 mg/L (0.2 mg/dm²) in China and 30 mg/L (5 mg/dm²) in the European Union. The factors used in the calculations included the specific surface area of food containers, daily food consumption rate, body weight, TDI, and the percentile of the population protected at a given migration concentration limit (MCL). The results indicate that children are indeed at higher risk of melamine exposure at toxic levels than are other groups and that the 95th percentile of MCL (specific surface area = 5) for children aged 1–6 years should be the RMCL (0.07 mg/dm²) for protecting the sensitive and general population.     

Tibetan minzu market: the intersection of ethnicity and commodity

In downtown Chengdu a pocket of Tibetan culture has sprung up: a Tibetan market where Tibetans and Han Chinese meet to buy and sell ethnic minority products. Pointing to how Tibetan migration to Chengdu has contributed to the growth of a vibrant ‘minzu market’ attracting Tibetan and Han Chinese merchants, customers, Buddhist devotees, and voyeurs, this article presents novel understandings of the ethnic goods market in urban Chengdu. The article first explores the growth of the market, which is the result of a history of political and economic reforms, increased mobility, and religious revival. Second, it maps the market infrastructure according to the ethnicity of the shopkeepers and the commodities that are traded. Although there is still a clear ethnic division in the market, this article also documents the emergence of Han Chinese market participation in forms of trade that have historically been dominated by Tibetans.     

Žumberak: A Sixteenth-Century Refugee Settlement Zone

This article examines the movement of Orthodox Christian refugees from Bosnia to the Habsburg Monarchy in the 1530s and their settlement in a district called ?umberak. The movement of these Uskoks has never been examined in the context of refugee studies. This study of a refugee movement and settlement over a five-century period offers the possibility of reaching a better understanding of the long-term outcome of refugee movements. Ultimately, this article suggests that the refugees affected the land they settled as much as the settlement zone affected them, and that, in this case, the refugees were able to define their own outcome.
