  emigration vs immigration biology: Origins and Destinations Renee Luthra, Roger Waldinger, Thomas Soehl, 2018-10-25 The children of immigrants continue a journey begun by their parents. Born or raised in the United States, this second generation now stands over 20 million strong. In this insightful new book, immigration scholars Renee Luthra, Thomas Soehl, and Roger Waldinger provide a fresh understanding the making of the second generation, bringing both their origins and destinations into view. Using surveys of second generation immigrant adults in New York and Los Angeles, Origins and Destinations explains why second generation experiences differ across national origin groups and why immigrant offspring with the same national background often follow different trajectories. Inter-group disparities stem from contexts of both emigration and immigration. Origin countries differ in value orientations: immigrant parents transmit lessons learned in varying contexts of emigration to children raised in the U.S. A system of migration control sifts immigrants by legal status, generating a context of immigration that favors some groups over others. Both contexts matter: schooling is higher among immigrant children from more secular societies (South Korea) than among those from more religious countries (the Philippines). When immigrant groups enter the U.S. migration system through a welcoming door, as opposed to one that makes authorized status difficult to achieve, education propels immigrant children to better jobs. Diversity is also evident among immigrant offspring whose parents stem from the same place. Immigrant children grow up with homeland connections, which can both hurt and harm: immigrant offspring get less schooling when a parent lives abroad, but more schooling if parents in the U.S. send money to relatives living abroad. Though all immigrants enter the U.S. as non-citizens, some instantly enjoy legal status, while others spend years in the shadows. Children born abroad, but raised in the U.S. are all everyday Americans, but only some have become de jure Americans, a difference yielding across-the-board positive effects, even among those who started out in the same country. Disentangling the sources of diversity among today’s population of immigrant offspring, Origins and Destinations provides a compelling new framework for understanding the second generation that is transforming America.

  emigration vs immigration biology: Migration and Mental Health Dinesh Bhugra, Susham Gupta, 2010-12-02 Human migration is a global phenomenon and is on the increase. It occurs as a result of 'push' factors (asylum, natural disaster), or as a result of 'pull' factors (seeking economic or educational improvement). Whatever the cause of the relocation, the outcome requires individuals to adjust to their new surroundings and cope with the stresses involved, and as a result, there is considerable potential for disruption to mental health. This volume explores all aspects of migration, on all scales, and its effect on mental health. It covers migration in the widest sense and does not limit itself to refugee studies. It covers issues specific to the elderly and the young, as well as providing practical tips for clinicians on how to improve their own cultural competence in the work setting. The book will be of interest to all mental health professionals and those involved in establishing health and social policy.

  emigration vs immigration biology: Lifestyle Migration Michaela Benson, 2016-05-06 Relatively affluent individuals from various corners of the globe are increasingly choosing to migrate, spurred on by the promise of a better and more fulfilling way of life within their destination. Despite its increasing scale, migration academics have yet to consolidate and establish lifestyle migration as a subfield of theoretical enquiry, until now. This volume offers a dynamic and holistic analysis of contemporary lifestyle migrations, exploring the expectations and aspirations which inform and drive migration alongside the realities of life within the destination. It also recognizes the structural conditions (and constraints) which frame lifestyle migration, laying the groundwork for further intellectual enquiry. Through rich empirical case studies this volume addresses this important and increasingly common form of migration in a manner that will interest scholars of mobility, migration, lifestyle and culture across the social sciences.

  emigration vs immigration biology: Migration, Environment and Climate Change Frank Laczko, Christine Aghazarm, 2009 Gradual and sudden environmental changes are resulting in substantial human movement and displacement, and the scale of such flows, both internal and cross-border, is expected to rise with unprecedented impacts on lives and livelihoods. Despite the potential challenge, there has been a lack of strategic thinking about this policy area partly due to a lack of data and empirical research on this topic. Adequately planning for and managing environmentallyinduced migration will be critical for human security. The papers in this volume were first presented at the Research Workshop on Migration and the Environment: Developing a Global Research Agenda held in Munich, Germany in April 2008. One of the key objectives on the Munich workshop was to address the need for more sound empirical research and identify priority areas of research for policy makers in the field of migration and the environment.
  emigration vs immigration biology: Traveling Cultures and Plants Andrea Pieroni, Ina Vandebroek, 2009-10 The tremendous increase in migrations and diasporas of human groups in the last decades are not only bringing along challenging issues for society, especially related to the economic and political management of multiculturalism and culturally effective health care, but they are also creating dramatic changes in traditional knowledge, believes and practices (KBP) related to (medicinal) plant use. The contributors to this volume – all internationally recognized scholars in the field of ethnobiology, transcultural pharmacy, and medical anthropology – analyze these dynamics of traditional knowledge in especially 12 selected case studies. Ina Vandebroek, features in Nova's Secret Life of Scientists, answering the question: just what is ethnobotany?
  emigration vs immigration biology: Animal Dispersal N.C. Stenseth, W.Z. Lidicker, 2012-12-06 4.1.1 Demographic significance Confined populations grow more rapidly than populations from which dispersal is permitted (Lidicker, 1975; Krebs, 1979; Tamarin et at., 1984), and demography in island populations where dispersal is restricted differs greatly from nearby mainland populations (Lidicker, 1973; Tamarin, 1977, 1978; Gliwicz, 1980), clearly demonstrating the demographic signi ficance of dispersal. The prevalence of dispersal in rapidly expanding populations is held to be the best evidence for presaturation dispersal. Because dispersal reduces the growth rate of source populations, it is generally believed that emigration is not balanced by immigration, and that mortality of emigrants occurs as a result of movement into a 'sink' of unfavourable habitat. If such dispersal is age- or sex-biased, the demo graphy of the population is markedly affected, as a consequence of differ ences in mortality in the dispersive sex or age class. Habitat heterogeneity consequently underlies this interpretation of dispersal and its demographic consequences, although the spatial variability of environments is rarely assessed in dispersal studies.

  emigration vs immigration biology: On the Move Filiz Garip, 2019-05-28 Why do Mexicans migrate to the United States? Is there a typical Mexican migrant? Beginning in the 1970s, survey data indicated that the average migrant was a young, unmarried man who was poor, undereducated, and in search of better employment opportunities. This is the general view that most Americans still hold of immigrants from Mexico. On the Move argues that not only does this view of Mexican migrants reinforce the stereotype of their undesirability, but it also fails to capture the true diversity of migrants from Mexico and their evolving migration patterns over time. Using survey data from over 145,000 Mexicans and in-depth interviews with nearly 140 Mexicans, Filiz Garip reveals a more accurate picture of Mexico-U.S migration. In the last fifty years there have been four primary waves: a male-dominated migration from rural areas in the 1960s and '70s, a second migration of young men from socioeconomically more well-off families during the 1980s, a migration of women joining spouses already in the United States in the late 1980s and ’90s, and a generation of more educated, urban migrants in the late 1990s and early 2000s. For each of these four stages, Garip examines the changing variety of reasons for why people migrate and migrants’ perceptions of their opportunities in Mexico and the United States. Looking at Mexico-U.S. migration during the last half century, On the Move uncovers the vast mechanisms underlying the flow of people moving between nations.

  emigration vs immigration biology: Immigration, Poverty, and Socioeconomic Inequality David Card, Steven Raphael, 2013-07-31 The rapid rise in the proportion of foreign-born residents in the United States since the mid-1960s is one of the most important demographic events of the past fifty years. The increase in immigration, especially among the less-skilled and less-educated, has prompted fears that the newcomers may have depressed the wages and employment of the native-born, burdened state and local budgets, and slowed the U.S. economy as a whole. Would the poverty rate be lower in the absence of immigration? How does the undocumented status of an increasing segment of the foreign-born population impact wages in the United States? In Immigration, Poverty, and Socioeconomic Inequality, noted labor economists David Card and Steven Raphael and an interdisciplinary team of scholars provide a comprehensive assessment of the costs and benefits of the latest era of immigration to the United States Immigration, Poverty, and Socioeconomic Inequality rigorously explores shifts in population trends, labor market competition, and socioeconomic segregation to investigate how the recent rise in immigration affects economic disadvantage in the United States. Giovanni Peri analyzes the changing skill composition of immigrants to the United States over the past two decades to assess their impact on the labor market outcomes of native-born workers. Despite concerns over labor market competition, he shows that the overall effect has been benign for most native groups. Moreover, immigration appears to have had negligible impacts on native poverty rates. Ethan Lewis examines whether differences in English proficiency explain this lack of competition between immigrant and native-born workers. He finds that parallel Spanish-speaking labor markets emerge in areas where Spanish speakers are sufficiently numerous, thereby limiting the impact of immigration on the wages of native-born residents. While the increase in the number of immigrants may not necessarily hurt the job prospects of native-born workers, low-skilled migration appears to suppress the wages of immigrants themselves. Michael Stoll shows that linguistic isolation and residential crowding in specific metropolitan areas has contributed to high poverty rates among immigrants. Have these economic disadvantages among low-skilled immigrants increased their dependence on the U.S. social safety net? Marianne Bitler and Hilary Hoynes analyze the consequences of welfare reform, which limited eligibility for major cash assistance programs. Their analysis documents sizable declines in program participation for foreign-born families since the 1990s and suggests that the safety net has become less effective in lowering child poverty among immigrant households. As the debate over immigration reform reemerges on the national agenda, Immigration, Poverty, and Socioeconomic Inequality provides a timely and authoritative review of the immigrant experience in the United States. With its wealth of data and intriguing hypotheses, the volume is an essential addition to the field of immigration studies. A Volume in the National Poverty Center Series on Poverty and Public Policy

  emigration vs immigration biology: Migrant Hospitalities in the Mediterranean Vanessa Grotti, Marc Brightman, 2021-01-10 This book applies insights from the anthropology of hospitality to illuminate ethnographic accounts of migrant reception in various parts of the Mediterranean. Anthropology has revisited the concept of hospitality in recent years, particularly through perspectives of ethnographers of the Mediterranean, who ground the idea and practice of hospitality in concrete ethnographic settings and challenge how the casual usage of Derridean or Kantian notions of hospitality can blur the boundaries between social scales and between metaphor and practice. Host-guest relations are multiplied through pregnancy and childbirth, and new forms of hospitality emerge with the need to offer mortuary practices for dead strangers. The volume makes no pretension to attempt to define a distinctive Mediterranean hospitality, but rather it seeks to explore the rich potential of the concept of hospitality to illuminate the spatial and scalar dimensions of morality and politics in Mediterranean migrant reception.

  emigration vs immigration biology: International Migrations in the Victorian Era , 2018-05-23 On account of its remarkable reach as well as its variety of schemes and features, migration in the Victorian era is a paramount chapter of the history of worldwide migrations and diasporas. Indeed, Victorian Britain was both a land of emigration and immigration. International Migrations in the Victorian Era covers a wide range of case studies to unveil the complexity of transnational circulations and connections in the 19th century. Combining micro- and macro-studies, this volume looks into the history of the British Empire, 19th century international migration networks, as well as the causes and consequences of Victorian migrations and how technological, social, political, and cultural transformations, mainly initiated by the Industrial Revolution, considerably impacted on people’s movements. It presents a history of migration grounded on people, structural forces and migration processes that bound societies together. Rather than focussing on distinct territorial units, International Migrations in the Victorian Era balances different scales of analysis: individual, local, regional, national and transnational. Contributors are: Rebecca Bates, Sally Brooke Cameron, Milosz K. Cybowski, Nicole Davis, Anne-Catherine De Bouvier, Claire Deligny, Elizabeth Dillenburg, Nicolas Garnier, Trevor Harris, Kathrin Levitan, Véronique Molinari, Ipshita Nath, Jude Piesse, Daniel Renshaw, Eric Richards, Sue Silberberg, Ben Szreter, Géraldine Vaughan, Briony Wickes, Rhiannon Heledd Williams.

  emigration vs immigration biology: Birds of Two Worlds Russell Greenberg, Peter P. Marra, 2005-05-02 For centuries biologists have tried to understand the underpinnings of avian migration: where birds go and why, why some migrate and some do not, how they adapt to a changing environment, and how migratory systems evolve. Twenty-five years ago the answers to many of these questions were addressed by a collection of migration experts in Keast and Morton's classic work Migrant Birds in the Neotropics. In 1992, Hagan and Johnston published a follow-up book, Ecology and Conservation of Neotropical Migrant Landbirds. In Birds of Two Worlds Russell Greenberg and Peter Marra bring together the world's experts on avian migration to discuss its ecology and evolution. The contributors move the discussion of migration to a global stage, looking at all avian migration systems and delving deeper into the evolutionary foundations of migratory behavior. Readers interested in the biology, behavior, ecology, and evolution of birds have waited a decade to see a worthy successor to the earlier classics. Birds of Two Worlds will complete the trilogy and become indispensable for ornithologists, evolutionary biologists, serious birders, and public and academic libraries.
  emigration vs immigration biology: Migration : The Biology of Life on the Move Davis Hugh Dingle Professor in the Department of Entomology and Center for Population Biology University of California, 1996-01-18 Migration is one of the most fascinating and dramatic of all animal behaviors. Historically, however, the study of migration has been fragmented, with ornithologists, entomologists, and marine biologists paying little attention to work outside their own fields. This treatment of the subject shows how comparisons across taxa can in fact illuminate migratory life cycles and the relation of migration to other movements. The book thus takes an integrated ecological perspective, focusing on migration as a biological phenomenon. The work is divided into four parts, each with a brief introductory section. Part I defines migration, gives examples, and places migration in the spectrum of movement behaviors, concluding with a chapter on methods for its study. Part II focuses on proximate mechanisms, including physiology and morphology (and the constraints associated with them), the interactions between migration and wind and current patterns, and the various orientation and navigation mechanisms by which migrants find their way about. Part III on the evolution of migratory life histories addresses the evolutionary and ecological basis for migration and the roles of migration not only in the lives of organisms, but also in the ecological communities in which they live. Part IV is devoted to a brief consideration of migration and its relation to pest management and conservation. As a major contribution to a vital subject, this work will be valued by all researchers and students in the field of animal behavior, ecology, and zoology.
  emigration vs immigration biology: The Oxford Handbook of Migration Crises Dr. Cecilia Menjívar, Dr. Marie Ruiz, Dr. Immanuel Ness, 2019-01-16 The objective of The Oxford Handbook of Migration Crises is to deconstruct, question, and redefine through a critical lens what is commonly understood as migration crises. The volume covers a wide range of historical, economic, social, political, and environmental conditions that generate migration crises around the globe. At the same time, it illuminates how the media and public officials play a major role in framing migratory flows as crises. The volume brings together an exceptional group of scholars from around the world to critically examine migration crises and to revisit the notion of crisis through the context in which permanent and non-permanent migration flows occur. The Oxford Handbook of Migration Crises offers an understanding of individuals in societies, socio-economic structures, and group processes. Focusing on migrants' departures and arrivals in all continents, this comprehensive handbook explores the social dynamics of migration crises, with an emphasis on factors that propel these flows as well as the actors that play a role in classifying them and in addressing them. The volume is organized into nine sections. The first section provides a historical overview of the link between migration and crises. The second looks at how migration crises are constructed, while the third section contextualizes the causes and effects of protracted conflicts in producing crises. The fourth focuses on the role of climate and the environment in generating migration crises, while the fifth section examines these migratory flows in migration corridors and transit countries. The sixth section looks at policy responses to migratory flows, The last three sections look at the role media and visual culture, gender, and immigrant incorporation play in migration crises.
  emigration vs immigration biology: Debating the Ethics of Immigration Christopher Heath Wellman, Phillip Cole, 2011-09-30 Do states have the right to prevent potential immigrants from crossing their borders, or should people have the freedom to migrate and settle wherever they wish? Christopher Heath Wellman and Phillip Cole develop and defend opposing answers to this timely and important question. Appealing to the right to freedom of association, Wellman contends that legitimate states have broad discretion to exclude potential immigrants, even those who desperately seek to enter. Against this, Cole argues that the commitment to the moral equality of all human beings - which legitimate states can be expected to hold - means national borders must be open: equal respect requires equal access, both to territory and membership; and that the idea of open borders is less radical than it seems when we consider how many territorial and community boundaries have this open nature. In addition to engaging with each other's arguments, Wellman and Cole address a range of central questions and prominent positions on this topic. The authors therefore provide a critical overview of the major contributions to the ethics of migration, as well as developing original, provocative positions of their own.
  emigration vs immigration biology: Mechanisms of Migration in Fishes James D. McCleave, 2013-03-13 The last major synthesis of our knowledge of fish migration and the underlying transport and guidance phenomena, both physical and biological, was Fish Migration published 16 years ago by F.R. Harden Jones (1968). That synthesis was based largely upon what could be gleaned by classical fishery-biology techni.ques, such as tagging and recapture studies, commercial fishing statistics, and netting and trapping studies. Despite the fact that Harden Jones also provided, with a good deal of thought and speculation, a theoretical basis for studying the various aspects of fish migration and migratory orientation, progress in this field has been, with a few excepti.ons, piecemeal and more disjointed than might have been expected. Thus we welcomed the approach from the NATO Marine Sciences Programme Panel and the encouragement from F.R. Harden Jones to develop a proprosal for, and ultimately to organize, a NATO Advanced Research Institute (ARI) on mechanisms of fish migration. Substantial progress had been made with descriptive, analytical and predictive approaches to fish migration since the appearance of Fish ~ligration. Both because of the progress and the often conflicting results of research, we felt that the time was again right and the effort justified to synthesize and to critically assess our knowledge. Our ultimate aim was to identify the gains and shortcomings and to develop testable hypotheses for the next decade or two.
  emigration vs immigration biology: Migration and Democracy Abel Escribà-Folch, Joseph Wright, Covadonga Meseguer, 2022-01-11 How remittances—money sent by workers back to their home countries—support democratic expansion In the growing body of work on democracy, little attention has been paid to its links with migration. Migration and Democracy focuses on the effects of worker remittances—money sent by migrants back to their home countries—and how these resources shape political action in the Global South. Remittances are not only the largest source of foreign income in most autocratic countries, but also, in contrast to foreign aid or international investment, flow directly to citizens. As a result, they provide resources that make political opposition possible, and they decrease government dependency, undermining the patronage strategies underpinning authoritarianism. The authors discuss how international migration produces a decentralized flow of income that generally circumvents governments to reach citizens who act as democratizing agents. Documenting why dictatorships fall and how this process has changed in the last three decades, the authors show that remittances increase the likelihood of protest and reduce electoral support for authoritarian incumbents. Combining global macroanalysis with microdata and case studies of Senegal and Cambodia, Migration and Democracy demonstrates how remittances—and the movement of people from authoritarian nations to higher-income countries—foster democracy and its expansion.
  emigration vs immigration biology: The Economics of International Migration Giovanni Peri, 2016-01-07 The Economics of International Migration is a collection of the fundamental articles written by Giovanni Peri on the economic determinants and consequences of international migration. These papers have provided the theoretical framework and empirical analysis for a rethinking of the economics of migration, going beyond the Canonical model of labor demand and supply used until the 1990s. Beginning with a simple model that recognizes the differences between immigrants and natives as workers, the articles develop the analysis of complementarity, specialization and productivity effect of immigrants in developed economies. The book then presents a series of papers analyzing and testing the economic motivation for international migration. Finally, the focus is shifted to the effect of immigration policies and their consequences on immigration and the economy.
