Contemporary immigration to the United States and the formation of new ethnic groups are the complex and unintended social consequences of the expansion of the nation to its post-World War II position of global hegemony. Immigrant communities in the United States today are related to a history of American military, political, economic, and cultural involvement and intervention in the sending countries, especially in Asia and the Caribbean Basin, and to the linkages that are formed in the process that open a variety of legal and illegal migration pathways. The 19.8 million foreign-born persons counted in the 1990 U.S. census formed the largest immigrant population in the world, though in relative terms, only 7.9% of the U.S. population was foreign-born, a lower proportion than earlier in this century. Today's immigrants are extraordinarily diverse, a reflection of polar-opposite types of migrations embedded in very different historical and structural contexts. Also, unlike the expanding economy that absorbed earlier flows from Europe, since the 1970s new immigrants have entered an hourglass economy with reduced opportunities for social mobility, particularly among the less educated, and new waves of refugees have entered a welfare state with expanded opportunities for public assistance. This paper seeks to make sense of the new diversity. A typology of contemporary immigrants is presented, and their patterns of settlement, their distinctive social and economic characteristics compared to major native-born racial-ethnic groups, and their different modes of incorporation in—and consequences for—American society are considered.  相似文献

The Abu Sayyaf is an organization which has left a trail of mayhem and murder in the southern Philippines for more than a decade. It has gained international notoriety through several high profile mass kidnappings. This article looks at how the Abu Sayyaf has managed to survive and at times prosper despite the state's efforts to eradicate it. By using organizational analysis the paper demonstrates how the Abu Sayyaf has developed structures and processes which make it such a deadly force. The organization has succeeded in gaining considerable fit with the environment in which it operates.  相似文献

从现在到2020年是打赢脱贫攻坚战的关键时期,从农民自身角度研究搬迁意愿,对加快实施易地扶贫移民搬迁具有重要意义。研究依据西方微观人口迁移理论:地方效用理论、计划行为理论和效价[CD*2]期望理论,整合构建了中国国情下由政府引导的易地扶贫搬迁意愿的理论分析框架。以陕南移民搬迁为例,在验证性因子分析的基础上,运用有序Logit模型和最优尺度模型对理论假设进行检验。结果显示:①心理因素、政策和预期因素、环境因素对搬迁意愿具有显著影响 ②控制变量中家庭人口数、非农劳动力比例、家庭成员求学婚姻等控制变量与搬迁意愿显著相关;③没有搬迁的主要的顾虑是搬迁后找不到工作、城镇生活成本高、搬迁成本高、搬迁后的适应等问题。研究建议政府部门在搬迁补助、就业安置、搬迁后适应等方面加大支持力度,增强搬迁的信心。  相似文献

党的十八、十九大均指出,生态文明建设功在当代、利在千秋。十九大进一步明确提出要构建“政府主导、社会协同、公众参与、法治保障”的生态文明建设新局面。《环境保护公众参与办法》的出台为公众参与环境保护提供了强有力的制度保障,但公众的参与程度与许多因素有关。在积极发动和鼓励公众参与生态文明建设的过程中,政府可发挥新媒体协商平台的作用,提高新媒体的回应能力,为公众参与生态文明建设提供保障;公众应借助新媒体互动平台的功能,进一步提升生态意识,践行生态行为,自觉维护生态环境;环保组织要发挥新媒体的聚焦作用,推动环保组织的成长壮大。  相似文献

From the Cold War era of the ‘veteran heroes’ to the present view of escaped North Koreans in terms more akin to ‘refugees’ and sometimes even just ‘migrants’, perceptions of North Korean defectors in South Korea have changed as swiftly as the number and origins of Northerners entering the South have expanded. At the same time, government policy for these ethnic ‘brethren’ has evolved considerably, particularly as South Korea has seen fundamental shifts in its independent identity, with important repercussions for the way its citizens view themselves as a collective. This article explores some of the key influences behind changes to policy and perceptions regarding North Korean people in South Korea over the period from 1997 to 2012, by applying international relations theory on national identity and its role in policy formation and change through the need to secure different parameters within that identity.  相似文献

公民环境教育的目标问题是有关环境教育研究领域的一个重要方向。全面而系统的公民环境教育目标谱系应该包含知识、技能、意识、伦理、行为、评价与建议以及意愿等七个维度。而七个维度目标之间的互利共生是公民环境教育层次提升、效果提高的必由之路。  相似文献

文章基于政府主导视角,利用2006—2015年我国30个省级面板数据,构建多元回归模型,分析变量之间的关系.其结果显示,环境管制、知识产权保护与区域创新能力之间呈非线性关系,环境管制与知识产权保护同时实施对区域创新能力有显著的促进作用,且具有区域异质性.从企业生存角度出发,提出门槛效应假说,采用Hansen面板门槛回归模型进行检验.结果表明,在环境管制与知识产权保护共同发挥作用时,环境管制必须控制在合理的范围内.最后采用门槛效应回归方法找到了环境管制与知识产权保护对区域创新能力影响的门槛值,并提出相应的政策建议.  相似文献

Anthropogenic climate change information tends to be interpreted against the backdrop of initial environmental beliefs, which can lead to some people being resistant toward the information. In this article (N = 88), we examined whether self‐affirmation via reflection on personally important values could attenuate the impact of initial beliefs on the acceptance of anthropogenic climate change evidence. Our findings showed that initial beliefs about the human impact on ecological stability influenced the acceptance of information only among nonaffirmed participants. Self‐affirmed participants who were initially resistant toward the information showed stronger beliefs in the existence of climate change risks and greater acknowledgment that individual efficacy has a role to play in reducing climate change risks than did their nonaffirmed counterparts.  相似文献

Repressive powers require not only obedience on the part of the oppressed but also denial of the oppressive nature of their submission. While authoritarian governments are the focus of this article, this applies to any oppressive relationship. There is a slippery slope from experiencing the imposed nature of the oppressive rules to adapting to them to denying both internal and external evidence of their existence. To prevent that declining process becomes an urgent priority when totalitarianism appears on the political and interpersonal horizon, as it is to help people coming out of tyranny – therapists included – to recover the words and the agency lost in their previous experiences.  相似文献
