    A survey was undertaken by the Chinese Academy of Sciences in 1986 to explore the composition and patterns of rural population movements. 230 villages were selected from 84 townships in 59 counties scattered across 11 regions. Because of incomplete information, only data for 222 villages were used. Population flows were classified into: 1) intramigration or intraflow within the boundaries of their own townships; 2) out-migration, emigration, or outflow involving those who left the townships; and 3) in-migration, immigration, or inflow that affected those who moved into the 222 villages from outside. Age, sex, education, postmigration occupation, and duration of stay details were obtained for every migrant. Some 43,223 persons were involved in intraflows and 26,993 emigrated from the surveyed townships in 1986. The volume of internal migration in China seemed to be related to the distance between the origins and destinations of migrants. Among 70,216 migrants, about 74% were males and only 26% were females. Over 57.38% of the migrants from 222 villages shifted into industrial (34.31%) and construction (23.07%) activities. The service sector (food providers, stall holders, door-to-door retailers, barbers, and small shops) attracted 9.73%. Only 565 were engaged in cropping and 1614 in forestry, animal husbandry, sideline production, and fishery. As to age groups, 1688 (2.4%) were aged 17 years or under, 61,530 (88%) were aged 18-45, and 6999 (9.9%) were 46 years old or older. In 1986 seasonal migrants accounted for some 80% of all emigrants from the surveyed villages. Education did not play a significant role in promoting migration in the mid-1980s. 39% of the labor force had received primary education and the same percentage of out-migrants had acquired primary school education. The younger the age group, the more of them tended to move away from home: for those aged 17 or under if 100 persons migrated within the township, 113 moved out of town. A nationwide network

    The objective is to summarize the pattern of Egyptian migration to Arab oil-producing countries (AOPC), to review some factors that are important determinants of labor movement based on theory, and to empirically model the migration rate to AOPC and to Saudi Arabia. Factors are differentiated as to their relative importance. Push factors are the low wages, high inflation rate, and high population density in Egypt; pull factors are higher wages. It is predicted that an increase in income from destination countries has a significant positive impact on the migration rate. An increase in population density stimulates migration. An increase in inflation acts to increase out-migration with a 2-year lag, which accommodates departure preparation. Egypt's experience with labor migration is described for the pre-oil boom, and the post-oil boom. Several estimates of labor migration are given. Government policy toward migration is positive. Theory postulates migration to be determined by differences in the availability of labor, labor rewards between destination and origin, and the cost of migration. In the empirical model, push factors are population density, the current inflation rate, and the ratio of income/capita in AOPC to Egypt. The results indicate that the ratio of income/capita had a strong pull impact and population density had a strong push impact. The inflation rate has a positive impact with a lag estimated at 2 years. Prior to the Camp David Accord, there was a significant decrease in the number of Egyptian migrants due to political tension. The findings support the classical theory of factor mobility. The consequences of migration on the Egyptian economy have been adverse. Future models should disaggregate data because chronic shortages exist in some parts of the labor market. Manpower needs assessment would be helpful for policy makers.

  3. Philippine migration policy: dilemmas of a crisis.

    Philippine migration policy is traced from the early 1970s to the present. The main migration trends in the 1990s are described. An assessment is made of the efficacy and appropriateness of present migration policy in light of the economic crisis. A regional approach to migration policy is necessary in order to encourage placing migration as a greater priority on national agendas and in bilateral agreements. In the Philippines, migrants are considered better paid workers, which diminishes their importance as a legislative or program priority. Santo Tomas (1998) conducted an empirical assessment of migration policies in the Philippines, but refinement is needed. Although migration is a transnational experience, there is little dialogue and cooperation among countries. Philippine migration policy defines its role as an information resource for migrants. Policy shifted from labor export to migrant management in the public and private sectors. Predeparture information program studies are recommending a multi-stage process that would involve all appropriate parties. There is talk of including migration information in the education curriculum. There are a variety of agendas, competing interests, and information resources between migration networks and officiating agencies. The Asian financial crisis may have a mild impact, but there are still issues of reintegration, protection, and employment conditions

    The objective of this discussion is to identify policies and programs in Asia that are explicitly or implicitly designed to influence migration, to investigate why they were adopted and how far they have actually been implemented, and to assess their direct and indirect consequences. For study purposes, policies and programs are classified according to whether they prohibit or reverse migration, redirect or channel migration to specific rural or urban locations, reduce the total volume of migration, or encourage or discourage urban in-migration. Discussion of each type of policy is accompanied by a description of its rationale and implementation mechanism, examples of countries in Asia that have recourse to it, and its intended or actual effect on migration. Several countries in Asia have taken direct measures to reverse the flow of migration and to stop or discourage migration to urban areas. These measures have included administrative and legal controls, police registration, and direct "rustication" programs to remove urban inhabitants to the countryside. The availability of public land has prompted many Asian countries to adopt schemes that have been labeled resettlement, transmigration, colonization, or land development. These schemes have been designed to realize 1 or more of the following objectives: to provide land and income to the landless; increase agricultural production; correct spatial imbalances in the distribution of population; or exploit frontier lands for reasons of national security. 1 of the basic goals of decentralized industrialization and regional development policies has been the reduction of interregional disparities and the redirection of migrations from large metropolitan areas to smaller and medium sized towns. To encourage industry to move to small urban locations initial infrastructure investments, tax benefits, and other incentives have been offered. Policies to reduce the overall volume of migration have frequently included rural

    Full Text Available This paper analyses the determinants of Romanian emigration considering two perspectives: first, the perspective of business environment and labour market and, second, the perspective of social and economic conditions. The analysis uses data from National Statistical Institute and Romanian Register of Commerce for all 42 counties of Romania for the year 2011 and consists of three linear regression models whose dependent variable was the total number of Romanian emigrants declared at 2011 Romanian Census. Results have shown that international migration is strongly correlated with national labour policy. The fact that newly created enterprises have a positive influence on migration show that Romanian business environment is not able to offer competitive salaries and/or working conditions.

    Major haemoglobinopathies (MH), such as thalassaemia syndromes (Thal) and sickle cell disorders (SCD), are genetic defects associated with chronic anaemia and other complications. In Europe, MH are rare diseases (RD) but their prevalence is significantly growing in many countries due to mobility and migration flows. This creates a growing health problem in the EU that has not yet been effectively addressed by Member States (MS) authorities. The present study has been conducted with the aim of: (i) providing an overview of policies for MH in 10 EU member states (MS) (ii) analysing the challenges linked to these RD due to growing requirements imposed by population, mobility and migration trends and (iii) identifying gaps, proposing improvements on existing policies, or developing new ones to fit the identified needs. The study has been undertaken by a group of members of the European Network for Rare and Congenital Anaemias (ENERCA) and the Thalassaemia International Federation (TIF), in collaboration with the public affairs firm Burson-Marsteller Brussels. Data from 10 EU countries have been gathered using targeted desk research and one-to-one interviews with local stakeholders, including healthcare professionals, patients and public health officers/providers. 1. MH are the most common RD in all the 10 countries, 2. Data on prevalence, overall burden, trends, and clinical follow up costs are lacking in most countries. 3. Neonatal screening practices show a wide variation across and within countries. 4. Awareness on MH and their related complications is very low, exception made of Italy, Greece, Cyprus and UK, 5. No disaggregated data is available to understand the impact of mobility and migration on the prevalence of haemoglobinopathies, and how healthcare delivery systems should adapt to respond to this situation. 6. Targeted policy measures and/or actions are generally lacking and/or delayed. Ten policy recommendations have been drawn from this study, building on

    The population of Indonesia is 175 million, of which 65% live in Java. Java has only 7% of the land area, causing a population density of 2,000/square mile. This has lead the government to introduce a policy of transmigration which encourages people to move from Java to the larger outer islands. In the last 35 years 4.3 million people have moved from Java to Sumatra, Borneo, Celebes, and Irian Jaya. The total area of Indonesia stretches over 3,200 miles and has 16,000 islands of which 1,000 are inhabited. It has vast resources of oil, lumber, rubber, tin, palm oil, copra, coffee, tea, pepper, cloves, nutmeg, and quinine. Indonesia is also rich in minerals, including coal, bauxite, iron ore, and gold. Even with a national family planning program, population growth has reached 2.1% a year. 3 other islands that people are induced to move from are Madura, Bali, and Lombok, although their population densities are less then Java. The small islands near Singapore are being developed and Batam will be a free port to compete with Hong Kong. The most intense migration has been to Kalimantan (Borneo) which has 4 provinces. The migration policy began in 1905 and by 1930 100,000 people, had moved to other islands; 600,000 people were relocated to plantations in Java for labor needs. In 1979-84, a more ambitious program costing 2.3 billion moved 1.5 million people. In the most recent 1984-89 plan, a goal of 3.1 million were to be relocated but due to budgetary restrictions only 150,000 families have moved. The main social issue addresses the domination of other people by Javanese, not only in numbers but cultural differences. Some observers say the real reason for migration is political in ensuring the boundaries and geographic integrity of Indonesia.

    Full Text Available Since economic factors cannot fully explain the determinants of bilateral migration, this study explores the social and cultural determinants that influence an individual’s decision to migrate. Values, norms and interests in a given culture, may determine whether an individual’s intention to move translates into actual migration. Work values inherent in different cultures could explain why people move or do not move under the condition of perceived economic advantages of migration. A gravity type migration model is used to incorporate variables related both to economic indicators and work values. It is perhaps the first migration study to use the World Value Survey (WVS and the European Value Survey (EVS. We use 2000 stock bilateral migration dataset collected by the World Bank. Our findings indicate that if more aspects of work are valued in a country, this country sends more migrants. Also we show that countries with higher extrinsic work value orientation tend to send more migrants, while countries with higher intrinsic work value orientation tend to send fewer migrants. Our finding shows that the value of work and the level of job security in a country may significantly change migration decision.

    Full Text Available In the last decades, after the Cold War and the fall of the Berlin wall, the strengthening of overall population mobility is evident on local, regional, national and global scale. In addition, there are changes in the scope and direction of migration, their structural characteristics and increasing in the number of determining factors and consequences, which affects the complexity of this phenomenon. It is important to point out the emergence of new forms of migration as a result of intensifying pace of globalization, which is an integral part of the migration. The total number of migrants in the world (internal and external in the first decade of the XXI century reached the highest value in history and is around one billion, with small, but continuous increase in share of total population. This means that one in every seven person in the world has changed place of residence, either within their own country (about 700 million of internal migrants or moved to another country (244 million international migrants. Therefore some authors points out that all of us are becoming migrants. Also, the number of irregular migrants recently has reached its highest amount, which implies an intensification of government actions to regulate migration through the creation of effective policies, spatial mobility and intensification of bilateral, regional and international negotiations in this domain. Estimates show that the number of migrants will continue to grow, especially the number of climate migrants, persons who left their homes due to changes in the environment. That is why it is of crucial importance in a first place to understand migrations properly and then to create the steps towards the best solutions in solving the problems caused by population movement in space and create proper migration policies.

To the best of our knowledge this is the first study on interregional population flows in Central Asia. We find that migration is determined by economic factors, first of all income: People are more likely to leave regions where incomes are low and more likely to move to regions with a higher income level. Furthermore, mobility is larger bet...

  14. Ethnicity, Migration and the 'Social Determinants of Health' Agenda

    Directory of Open Access Journals (Sweden)

    David Ingleby

    2012-12-01

    Full Text Available One of the most promising recent developments in health policy has been the emergence of a global 'health equity' movement concerned with the social determinants of health. In European research and policy-making, however, there is an strong tendency to reduce 'social determinants' to 'socioeconomic determinants' and to ignore the role of ethnicity, migration and other factors in the creation of inequities. This threatens to hold up the development of work on ethnicity and migration and thus to perpetuate inequities linked to these factors. The present article sets out to illustrate this tendency and to investigate the reasons which may underlie it. The justifications often put forward for neglecting ethnicity and migration are shown to be erroneous. An integrated approach, simultaneously taking account of socioeconomic status, migration and ethnicity as well as other determinants of inequity, is essential if work on the social determinants of health is to make progress. Equity is indivisible; researchers investigating different aspects of social stratification should not treat each other as rivals, but as indispensible allies. An integrated, intersectional, multivariate and multilevel approach will improve our understanding of health inequities and make available more resources for tackling them.

    Full Text Available In the second half of the XX century, the humankind witnessed the insurmountable and irreversible power of globalization processes, which influence all spheres of social life and establish a global system of interdependency between countries and nations. Globalization within impetuous changes in global political, social and economic systems has determined dramatic shifts in the international migration processes that lead to the new stage of migration history. In nowadays globalized world, international migration has become a reality for almost all corners of the globe. The author considers features of the recent trends of international migration: the unprecedented growth of the international migration flows; the widening geography of international migration that involves nearly all countries of the world; qualitative changes in the structure of international migration flows; the key role of economic migration; the permanent growth and structural intricateness of irregular migration; the increasing scale and geographical widening of forced migration; the growing importance of international migration for the demographic development of the world, countries of both origin and destination. All these trends combined prove that the international migration patterns have become more complex. The author analyzes the legal framework of the international migration processes, and gives recommendations on the ways to improve the control and regulation of migration processes. Specific issues related to the social challenges of international migration are also discussed in the article.

The systematization of these studies, historically placed on migration policies, aims to highlight some of the most significant contributions of the research during the last 30 years, to understand or explain various aspects and dimensions of the Argentinean migration policy. To achieve this, texts were selected that derived from empirical research that explicitly assume the migratory policies as the object of study, or whose themes and research problems adopt as a framework for discussion the policies and practices aimed at regulating migration and mobility in Argentina. The organization and presentation of these selected texts consider issues related to the interests and thematic concerns, disciplinary and analytical approaches, distinct periods, scales of analysis and sources of information.

    Full Text Available Immigration in Europe has been shaped by: a its particular development in time; b the geographical patterns of migration within and towards European countries; and c the shifting types of migration and characteristics of migrants involved. The first part of this contribution outlines changes in these three basic migration-related factors. Migration outcomes are not haphazard nor are these the result of unhindered economic push and pull factors in a free market. Immigration policies of receiving countries do greatly influence the volume and patterns of migration, the place of settlement and the characteristics of migrants. Regulations on conditions of residence and integration do furthermore influence significantly the position of immigrants in their new destination, among others by setting conditions for their stay (residence rights and access to the labour market. The second part of this chapter outlines the migration and integration regimes that have been developed by states of different parts of Europe and by the European Union. In conclusion, immigration has become a relevant phenomenon in all EU countries. However, as a consequence of different timing of immigration, different socio-economic contexts and varying governmental migration and integration policies, European countries are confronted with different forms migration (immigration, emigration, transit migration and with different types of migrants. European states have also developed different governmental policies of migration and integration. Historically, a common denominator in the framing of European policies is that countries do not see themselves as immigration countries; they are immigration countries against their will. In recent times, such framing is reinforced by populist and nationalist movements that see immigrants not only as economic competitors, but also as a threat to the national "culture and world views". The more Europe needs immigrants for economic and

    1988-12-01

    A government's international migration policies are intended to influence the size, composition, direction, destination, or integration of international migratory flows. The justification for migratory policies has been based on a series of themes that have had varied weights in different stages of Latin American history. Migrations as population settlement, the desired or undesired characteristics of migrants, the economic impact of migration, the role of migration in relations between countries, and the ethical dimensions of migratory movement have been the major policy issues. The 1st migration policies in Latin America saw international migration as a means of settling the colonies. After independence, migratory policies oriented toward massive settlement became common. Although the stated goals were to settle entire territories with immigrants, the usual result was to absorb immigrants in certain economic sectors with high demand for labor. In the colonial period both Spain and Portugal attempted to restrict immigration to the Catholic segment of their own populations. After independence, the criteria were liberalized somewhat but still reflected prejudices about the racial superiority of certain types of European immigration. The selection principals which appeared most clearly during the 19th century were overwhelmed to the extent that immigration was tranformed into provision of labor to meet unsatisfied needs for workers. Indiscriminate admissions and recourse to nontraditional elements such as Chinese and Japanese was strongest in countries needing labor for tropical agriculture or extractive industries. The economic argument that migration contributed to development was widespread economic argument that migration contributed to development was widespread in the 19th and early 20th centuries, but new rules were made to restrict immigration to protect local labor markets during the worldwide depression of the 1930s. In recent decades, migration policies

    Full Text Available This paper examines some determinants of international migration in Nigeria using annual time series data spanning the period 1991–2011. Using ordinary least square regression method, the results indicate that the level of unemployment, migrants’ remittances and population growth are the key determinants of emigration from Nigeria to other countries, statistically significant at 0.01 level.In a country where unemployment rate is very high, this movement is likely to help in reducing pressures on the labour market. Migrants’ remittances might also help in alleviating poverty within households. Migrants’ remittance to Nigeria has surpassed both Foreign Direct Investment and Net Official Development Assistance inflows, making it one amongst the major sources of foreign earnings to Nigeria. Nigerians will continue to migrate to other parts of the world so long as the reasons or causes for their movement are not fully addressed i.e. if political and socioeconomic issues in the country do not improve. The Nigerian government should as a matter of urgency, create better jobs and conducive environment in order to stop people from migrating while at the same time encouraging its skilled labour abroad to return home to help in national development.

    During the Chinese dynasties of Sui and Tang, neighboring minority groups were forced to migrate to less settled areas of China. During the Song dynasty (960-1279) the Han government lost control of neighboring ethnic groups. Ethnically dominated states on their own expanded to the hinterlands, formed the national governments of Yuan and Qing, and established the local power of Liao and Jin in Han-dominated areas. During the Han dynasty the movement of minorities fulfilled the purpose of helping cultivate undeveloped land. The Han governments of feudal China held compulsory migration policies and policies encouraging minorities to move to less inhabited places. Han governments prior to the Tang and Song dynasties held policies favorable to minority settlements. During the Tang dynasty land was given to minority settlers. During the Song dynasty the Han government held a policy which prohibited taxation and harassment of new minority settlers. Minorities gained improved living conditions and the government achieved pacification. Resettlement of minorities either from forced or voluntary migration facilitated communication with the Han and promoted the exchange of culture, but also intensified ethnic conflict. The reason for the ethnic conflict was a question of control. Ethnic governments encouraged in-migration and adopted policies of compulsory and voluntary migration. Ethnic minorities in the north and west practiced mainly compulsory migration. Ethnic conflict in the Qin and Han dynasties occurred between the Han and the Huns. During the Eastern Jin and Northern dynasties minority governments captured Han and other ethnic groups. The rule of minority government was strengthened by voluntary migration. The frequent power shifts in ancient China contributed to the blending of Chinese nationalities.

    "The various studies focussing on human settlements in Senegal show that the share of population living in cities is ever increasing because of the massive and continuous flow from rural areas. The persistance of such migration trends from the country to cities deepens regional disparities, compounds the difficulties and cost of city management and development, specially in the case of Dakar, and runs counter to the goals of social and economic development plans.... The growing importance of such phenomena calls for the designing of corrective measures in favour of rural areas and small towns in order to settle rural populations and halt the inordinate and chaotic geographical growth of large cities. Failing this, development efforts may well be compromised." (SUMMARY IN ENG) excerpt

    Without an equal sharing of costs and benefits of natural and human resources worldwide, imbalances and lack of human development lead to migration within and between countries. Economic integration blocks in Latin America provide a context for shared development: in Central America, in the Andean Region, and in the Southern Cone. Over the past 60 years migration policy was based on national protectionism, labor supply, and/or occupation of territory. When economic conditions changed to market economies and world markets, migration policy was redefined. Each of the economic integration blocks has developed its own strategies. The Andean Agreement on Labor Migrations was established to determine the rules for bilateral and multilateral treatment of problems. In the Southern Cone bilateral agreements have been longstanding. Multilateral efforts were recently underway within the Southern Common Market and throughout the region. The Central American Organization for Migrations has spearheaded the adoption of a multilateral strategy. All three regions have made considerable progress in the last three years in constructing multilateral policies for economic integration. Government awareness has been the primary force in these policy changes. Government has come to an understanding that clear domestic and regional migration policies were lacking and that obsolete migration practices of the 1930s did not meet the needs of the 1990s. Migration policy was considered an instrument of development. Movement of economic factors or goods was considered equally with movement of labor. Migration policies must integrate the human rights of migrants into their definitions. Methods of facilitating the movements of populations need to be constructed within the computerization and modernization of the migration administration. Legalization of illegal immigrants has occurred among a number of countries. PROCAM and PRIMCOS were action programs which aimed to integrate migration and

    Full Text Available In this paper I would like to present Serbian migration policy concerning irregular migration and asylum in the context of the attempts of the Serbian state to become a member of the European Union. I would describe the history of the asylum system prior and after the implementation of the independent asylum system in Serbia in 2008. My presentation of the Serbian migration policy would be channelled by the analysis of some particular political issues, such as the externalization of the EU borders’ control, as well as some relevant elements of the European integration process, like visa liberalization.

    2013-09-01

    Full Text Available The main idea of the paper states that national migration indicators are closely related with employment opportunities in that country. In addition, the management quality of migration and employment processes is an indicator of the national socio-economic policy competency, while management of these processes is the main purpose of intelligent adjustment of the national fiscal policy and government debt management. The author of the paper selected the formation of the system of quantitative indicators as the main objective of the paper. The system should allow employing government debt possibilities for the selection of proper fiscal policy in order to prevent the transformation of unemployment into the key reason of uncontrolled national inflation. This would be done by revealing the possibilities of fiscal policy to impact on the level and structure of unemployment. Recent globalisation processes and integration possibilities bring a lot of uncertainty to predetermined viability of theoretical assumptions as well as the adequacy of the applied quantitative methods. The paper uses the possibilities of stochastic optimisation and stochastically informed expertise pursuing the possibilities of integrated management of employment, migration processes, fiscal policy and government debt provisions.

  9. The Determinants of Return Migration: Evidence for Kosovo

    Full Text Available Return migration represents a potentially important contributor to economic development for countries that are large exporters of labor. This paper provides an analysis of the determinants of return migration to Kosovo, a country with an especially high level of recent emigration. The findings of this investigation suggest that there is a non-linear relationship between the age of the migrant and their probability of returning. In addition, the more educated migrants and those that have acquired additional education whilst abroad are more likely to return, whereas recent migrants, those that possess permanent resident status and have their family abroad are less likely to return. As expected, the stronger the family ties of a migrant with their home country, the more likely they are to return. Finally, migrants that are expected to invest in businesses in Kosovo are more inclined to return. Together these findings suggest that return migration may be an important contributor to economic development in Kosovo and policies are outlined that could strengthen this contribution.

    Indonesia is recognized as a nurse exporting country, with policies that encourage nursing professionals to emigrate abroad. This includes the country's adoption of international principles attempting to protect Indonesian nurses that emigrate as well as the country's own participation in a bilateral trade and investment agreement, known as the Indonesia-Japan Economic Partnership Agreement that facilitates Indonesian nurse migration to Japan. Despite the potential trade and employment benefits from sending nurses abroad under the Indonesia-Japan Economic Partnership Agreement, Indonesia itself is suffering from a crisis in nursing capacity and ensuring adequate healthcare access for its own populations. This represents a distinct challenge for Indonesia in appropriately balancing domestic health workforce needs, employment, and training opportunities for Indonesian nurses, and the need to acknowledge the rights of nurses to freely migrate abroad. Hence, this article reviews the complex operational and ethical issues associated with Indonesian health worker migration under the Indonesia-Japan Economic Partnership Agreement. It also introduces a policy proposal to improve performance of the Indonesia-Japan Economic Partnership Agreement and better align it with international principles focused on equitable health worker migration.

    We develop a regional model where, in the city, unemployment prevails because of too high (efficiency) wages, while, in the rural area, workers are paid at their marginal productivity. We characterize the steady-state equilibrium and show that it is unique. We then consider two policies: decreasing urban unemployment benefits and subsidizing urban employment. We find that decreasing the unemployment benefit in the city creates urban jobs and reduces rural-urban migration since new migrants ha...

    Full Text Available This paper presents an analysis of internal migration in Mexico. Using micro data from the National Survey on Occupation and Employment (enoe, we estimate a multinomial logit model for the case of intrastate and interstate migration. We also conduct estimations for municipalities of different sizes. The results suggest that the probability of migrating increases with the number of weeks spent searching for a job, regardless of whether the search is conducted while the individual is employed or unemployed. In addition, we find that as the number of hours of work per week increases, the probability of migrating rises. The search process does not increase the probability of migrating in rural communities as it does in urban centers.

    Internal migration has had a great impact on Turkey’s population dynamics for decades. According to the 2000 population census, nearly 28% percent of the population was born in a different province that they now reside in. This ratio goes up to 62% for Istanbul, a major province that has drawn migrants for years. Although, it is claimed in numerous studies that rural-urban migration that centers on a few urban areas seems to be the predominant pattern of internal migration, we aim to investig...

    This study sought to better understand the drivers of skilled health professional migration, its consequences, and the various strategies countries have employed to mitigate its negative impacts. The study was conducted in four countries-Jamaica, India, the Philippines, and South Africa-that have historically been "sources" of health workers migrating to other countries. The aim of this paper is to present the findings from the Indian portion of the study. Data were collected using surveys of Indian generalist and specialist physicians, nurses, midwives, dentists, pharmacists, dieticians, and other allied health therapists. We also conducted structured interviews with key stakeholders representing government ministries, professional associations, regional health authorities, health care facilities, and educational institutions. Quantitative data were analyzed using descriptive statistics and regression models. Qualitative data were analyzed thematically. Shortages of health workers are evident in certain parts of India and in certain specialty areas, but the degree and nature of such shortages are difficult to determine due to the lack of evidence and health information. The relationship of such shortages to international migration is not clear. Policy responses to health worker migration are also similarly embedded in wider processes aimed at health workforce management, but overall, there is no clear policy agenda to manage health worker migration. Decision-makers in India present conflicting options about the need or desirability of curtailing migration. Consequences of health work migration on the Indian health care system are not easily discernable from other compounding factors. Research suggests that shortages of skilled health workers in India must be examined in relation to domestic policies on training, recruitment, and retention rather than viewed as a direct consequence of the international migration of health workers.

This article is devoted to the study of existing approaches to identification of main directions and priorities of state migration policy for eliminating of external migration negative effects in Ukraine, ensuring an adequate level of social and economic protection of people and national security of Ukraine. The article considers the current problems of Ukraine's migration policy formation, characterizes the main priorities of Ukraine's migration policy according to its basic component, and describes the tendencies of migration processes in Ukraine and over the world. It is determined that the cooperation between Ukraine and the EU in the case of migratory flow regulating will have a number of advantages including the reduction of illegal migration, preservation of the professional level of Ukrainian migrants and receiving work experience abroad, strengthening their social protection and reduction of illegal employed migrants.

  3. Circular migration patterns and determinants in Nairobi slum settlements

    Directory of Open Access Journals (Sweden)

    Donatien Beguy

    2010-09-01

    Full Text Available This paper measures migration flows and determinants in two slum settlements in Nairobi City between 2003 and 2007. The results confirm the high intensity of migration with a quarter of the total slum population and a third of those aged 15-30 being renewed annually. A circular migration system is at play whereby the majority of slum dwellers are short-term migrants spending on average less than 3 years in the area. Migration is more intense during early adulthood (20-24, and despite very similar determinants across gender, mobility is more intense among women compared to men. The increasing feminization of migration is likely to change the face of slum settlements, resulting in more balanced sex ratios, in line with city-wide trends in Nairobi over the past half century. The high population turnover is due to the insecurity of livelihoods, tenure, and poor basic amenities and social services in slum settlements.

  4. Determinants of labour migration of elite sport coaches.

    Orlowski, Johannes; Wicker, Pamela; Breuer, Christoph

    2016-09-01

    Previous research examining labour migration in sport focused on athletes in professional team sports. The purpose of this study is to analyse the factors influencing the migration probability of elite sport coaches in Germany (i.e. national coaches, state coaches, and coaches at Olympic training bases). From a theoretical perspective, labour migration of athletes is affected by economic, social, political, competitive, geographic and cultural factors. This study examines whether these factors can be applied to coaches. Primary data were collected using an online survey of elite sport coaches in Germany. Applying a conjoint design, respondents were presented with 10 migration scenarios leading to a sample size of n = 1860 for the empirical analysis. In the scenarios, the coaching position openings abroad differed in terms of income level, contract length, weekly workload, responsibility for personnel, reputation of coaching job, career perspectives, sporting performance of athletes, distance from Germany, and predominant job language. Coaches were asked for their migration probability contingent on the specific scenario. On average, migration probability was 24.2%. The results of regression analysis showed that higher income, contracts of longer duration, responsibility for personnel and speaking the respective language significantly increased the migration probability, while distances of nine flight hours and more, lower reputation and career perspectives reduced it. The findings have implications for policy-makers: they indicate in what areas the situation of coaches needs improvement to increase the likelihood of retaining elite sport coaches in the German sport system.

  5. The Gravity of High-Skilled Migration Policies.

    Czaika, Mathias; Parsons, Christopher R

    2017-04-01

    Combining unique, annual, bilateral data on labor flows of highly skilled immigrants for 10 OECD destinations between 2000 and 2012, with new databases comprising both unilateral and bilateral policy instruments, we present the first judicious cross-country assessment of policies aimed to attract and select high-skilled workers. Points-based systems are much more effective in attracting and selecting high-skilled migrants than requiring a job offer, labor market tests, and shortage lists. Offers of permanent residency, while attracting the highly skilled, overall reduce the human capital content of labor flows because they prove more attractive to non-high-skilled workers. Bilateral recognition of diploma and social security agreements foster greater flows of high-skilled workers and improve the skill selectivity of immigrant flows. Conversely, double taxation agreements deter high-skilled migrants, although they do not alter overall skill selectivity. Our results are robust to a variety of empirical specifications that account for destination-specific amenities, multilateral resistance to migration, and the endogeneity of immigration policies.

  6. Towards understanding international migration determinants today: Theoretical perspective

    Predojević-Despić Jelena

    2010-01-01

    Full Text Available In times of global migration flows and ever increasing mobility of the workforce in the world, the necessity for constant deepening of theoretical knowledge is imposed as a basis for understanding main determinants of this phenomenon, and with an aim of directing the focus of migration researches towards more efficient overcoming of challenges and making use of the advantages which international migrations could bring both to origin, destination and transit countries. The main goal of this paper is to give a critical review on the development of the economic migrations theory, to state the main similarities and differences between various approaches and to point out to the main drawbacks and problems which the theoretical perspective is facing when studying the determinants of contemporary international labor migrations. The focus of the study refers to voluntary labor migrations with reference to migrations of the highly educated population, while the stress is on economic theories, although some of them are closely connected to sociological, geographical and anthropological theories. The development of the theory on international migrations has been started by micro theoretical models, namely, through the conceptualization of theories which place the individual in the focal point of research, who estimates the positive, namely negative sides of moving from one location to another. Economic models on the micro theoretical level cede more space to models of macro structure which research the social and economic structure within and between countries. There are many theoretical models which offer possible answers to the question on what are the main determinants of international migrations on the macro analytical level. Although every one of them tries to give an answer to the same question, they use different concepts, assumptions and frameworks of research. The reasons which bring about the initiation of international migrations can be

    This case study analyses current migration dynamics in two regions of Bolivia: Northern Potosi, one of the main areas of outmigration in Bolivia, and the municipality of San Julian in the Department of Santa Cruz, a major destination for internal migrants, some of whom come from Northern Potosi. The research was qualitative in nature, with specific attention to breadth and accuracy in the information and analysis. The methods used were participative and the research was done in collaboration with the rural and indigenous organisations in the two selected areas: the Federation of Indigenous Ayllus of Northern Potosi (Federacion de Ayllus Originarios Indigenas del Norte de Potosi Charka Qhara Qhara - FAOI-NP) and the Federation of Intercultural Communities of San Julian (Federacion de Comunidades Interculturales de San Julian). The information gathering process examined a wide range of factors that may trigger migration, including the possible influence of climate change and public policies on migration. The key challenge was to understand current patterns of migration, the processes involved and the social, cultural, economic and political causes and effects, taking into account issues that are increasing in importance, such as climate change, and seeking to discover the extent of their influence in the midst of other factors that drive migration. It is well known that migration is not a simple occurrence. In fact, it involves a series of processes, motivations, causes and decisions. Because it is a collective rather than an individual process, it takes on the character of a 'social phenomenon' that is historically and geographically determined. In many cases, there are cultural practices of transhumance, such as agriculture on different ecological levels or the use of winter and summer pastures. This involves people moving from one place to another, sometimes travelling long distances and crossing districts for several months at a time. These transhumance practices

    Environment migration research has sought to provide an account of how environmental risks and resources affect migration and mobility. Part of that effort has focused on the role of the environment in providing secure livelihoods through provisioning ecosystem services. However, many of the models of environment migration linkages fail to acknowledge the importance of social and psychological factors in the decision to migrate. Here, we seek to provide a more comprehensive model of migration decision-making under environmental change by investigating the attachment people form to place, and the role of the environment in creating that attachment. We hypothesize that environmental factors enter the migration decision-making process through their contribution to place utility, defined as a function of both affective and instrumental bonds to location, and that ecosystem services, the aspects of ecosystems that create wellbeing, contribute to both components of place utility. We test these ideas in four rural highland settlements in Peru sampled along an altitudinal gradient. We find that non-economic ecosystem services are important in creating place attachment and that ecological place attachment exists independently of use of provisioning ecosystem services. Individuals’ attitudes to ecosystem services vary with the type of ecosystem services available at a location and the degree of rurality. While social and economic factors are the dominant drivers of migration in these locations, a loss of non-provisioning ecosystem services leads to a decrease in place utility and commitment to place, determining factors in the decision to migrate. The findings suggest that policy interventions encouraging migration as an adaptation to environmental change will have limited success if they only focus on provisioning services. A much wider set of individuals will experience a decrease in place utility, and migration will be unable to alleviate that decrease since the factors

    Full Text Available Migration is a global phenomenon gradually increased in scope, impact and complexity. Practically all countries are simultaneously countries of destination, origin and transit for migrants. Traditionally migration flows are complemented by new changes generated by economic, demographic, political or social conditions, and these trends affect both the size and structure of the migrant population and also economies and societies. Of course this has sparked international interest from various NGOs and by the European Union and the United Nations. This paper aims to present the vision of international organizations concerned with migration and how they define migration and its typologies.

  14. Impact, regulation and health policy implications of physician migration in OECD countries

    2004-07-01

    Full Text Available Abstract Background In the face of rising demand for medical services due to ageing populations, physician migration flows are increasingly affecting the supply of physicians in Organisation for Economic Co-operation and development (OECD countries. This paper offers an integrated perspective on the impact of physician migration on home and host countries and discusses international regulation and policy approaches governing physician migration. Methods Information about migration flows, international regulation and policies governing physician migration were derived from two questionnaires sent to OECD countries, a secondary analysis of EUROSTAT Labour Force Surveys, a literature review and official policy documents of OECD countries. Results OECD countries increasingly perceive immigration of foreign physicians as a way of sustaining their physician workforce. As a result, countries have entered into international agreements regulating physician migration, although their success has been limited due to the imposition of licensing requirements and the protection of vested interests by domestic physicians. OECD countries have therefore adopted specific policies designed to stimulate the immigration of foreign physicians, whilst minimising its negative impact on the home country. Measures promoting immigration have included international recruitment campaigns, less strict immigration requirements and arrangements that foster shared learning between health care systems. Policies restricting the societal costs of physician emigration from developing countries such as good practice guidelines and taxes on host countries have not yet produced their expected effect or in some cases have not been established at all. Conclusions Although OECD countries generally favour long-term policies of national self-sufficiency to sustain their physician workforce, such policies usually co-exist with short-term or medium-term policies to attract foreign physicians

    High caesarean rates are of concern given associated risks. International migrant women (women born abroad) represent a substantial proportion of women giving birth in high-income countries (HICs) and face social conditions that may exacerbate childbearing health risks. Among migrant women, emergency rather than planned caesareans, tend to be more prevalent. This method of delivery can be stressful, physically harmful and result in an overall negative birth experience. Research establishing evidence of risk factors for emergency caesareans in migrants is insufficient. (1) Describe potential pathways (with a focus on modifiable factors) by which migration, using internationally recommended migration indicators: country of birth, length of time in country, fluency in receiving-country language, migration classification and ethnicity, may lead to emergency caesarean; and (2) propose a framework to guide future research for understanding "potentially preventable" emergency caesareans in migrant women living in HICs. "Potentially preventable" emergency caesareans in migrant women are likely due to several modifiable, interrelated factors pre-pregnancy, during pregnancy and during labour. Migration itself is a determinant and also shapes other determinants. Complications and ineffective labour progress and/or foetal distress and ultimately the decision to perform an emergency caesarean may be the result of poor health (i.e., physiological effects), lack of support and disempowerment (i.e., psychological effects) and sub-optimal care. Understanding the direct and indirect effects of migration on emergency caesarean is crucial so that targeted strategies can be developed and implemented for reducing unnecessary caesareans in this vulnerable population.

    "This paper reviews the literature on international labour migration from and within the Asian-Pacific region. It deals with patterns and characteristics of migration flows, government policies towards labour migration, and economic implications of labour migration for both labour-exporting and importing countries in the region. The indications are that, despite gradual slowing down of labour flows to the western industrial countries and the Middle East, labour migration will continue to be a major economic influence on surplus-labour countries in the region. As an integral part of the growth dynamism in the region, labour migration has now begun to take on a regional dimension, with immense implications for the process of industrial restructuring in high growth economies and the changing pattern of economic interdependence among countries." excerpt

  2. MIGRATION POLICIES AND STATE CONTROL IN ARGENTINA: EXPERIENCES OF VULNERABLE BOLIVIAN WOMEN WHO CROSS THE BORDERS

    2015-01-01

    Full Text Available This paper analyzes the way in which migration policies impact in the trajectories of Bolivian women who live and work in the outskirts of the main cities of Argentina. It focuses on three cases representative of the experiences of women laborers who, coming from the poorest rural areas of Bolivia, crossed the international border when Argentine migration policy was very restrictive. It shows that symbolic and socio-economic borders keep on excluding them, as well as other labor migrants, within the Argentine territory even when the current Migration Law enacted in 2004 is more inclusive, since it grants human and social rights to the migrants. It highlights the way in which particular state control mechanisms operate nowadays both at the international border and within the Argentine territory, and analyses the difficulties that these women experience due to their positions of class, ethnic, gender, nationality and migratory status. It remarks that despite the changes in the immigration policy of Argentina, state policies keep on controlling labor migrations in accordance with the paradigm of the governance of migration. It also analyses the strategies that these women develop in order to sort out state control policies. Therefore, it considers that they are active agents even though they still have feelings of fear and trauma associated with the crossing of borders.

    Full Text Available Objective – The objective of this article is to identify the determinants of non-financial companies' dividend policy of the Portuguese capital market and contribute to resolve the divergence of determinants of the dividend policy existent in previous studies. Design/methodology/approach – To solve the problematic under study were tested several financial determinants, through the application of the method of multiple linear regressions to the non-financial listed companies on the Euronext Lisbon, between 1997 and 2011. Findings – The results suggest as main indicators for the Portuguese dividend policy the stability, the value of the market, the previous pay-out and the business dimension; which influence positively the amount of dividends distribute through the company. Therefore, the opportunities of growing and investment influence negatively the distribution of dividends. Practical implications –Identify the principal determinants of the dividend policy of the non-financial companies listed on the Portuguese capital markets - Euronext Lisbon and allow sustaining and improving the corporations and investors’ decisions. Originality/value – This study opens up an opportunity to contribute to the understanding of the determinants of dividend policy of the listed corporations in the Lisbon Stock Exchange, aiming permeates greater scientific knowledge in the context of understanding the determinants of dividend puzzle policy and the existing divergences of several previous empirical studies.

    Full Text Available Importance Relevance of the chosen subject is caused as variety and unsystematic character of standard and legal base federal and first of all the regional level which regulates various parties of migration policy, and absence of legally established concepts of migration, migratory process and migration policy. Besides, recently it is possible to observe growth of mobility of labor force in the conditions of globalization which creates prerequisites for employment not only highly skilled professionals in the field of finance, insurance, banking, communications, but also the migrant workers occupied in the sphere of agriculture, construction, improvement of the territory, public catering, hotel service. Now the state is interested in attraction of foreign labor for ensuring the sustainable and balanced social and economic development of national regions, but is afraid of negative influence of migration on social and economic processes in theRussian Federation.

    The parameters of the atrazine migration in columns with undisturbed Vertisol sampled from an irrigated plot in Guanajuato, Mexico were determined. A model of the convection-dispersion transport of the chemical compounds accounting for the decomposition and equilibrium adsorption, which is widely applied for assessing the risk of contamination of natural waters with pesticides, was used. The model parameters were obtained by solving the inverse problem of the transport equation on the basis of laboratory experiments on the transport of the 18O isotope and atrazine in soil columns with an undisturbed structure at three filtration velocities. The model adequately described the experimental data at the individual selection of the parameters for each output curve. Physically unsubstantiated parameters of the atrazine adsorption and degradation were obtained when the parameter of the hydrodynamic dispersion was determined from the data on the 18O migration. The simulation also showed that the use of parameters obtained at water content close to saturation in the calculations for an unsaturated soil resulted in the overestimation of the leaching rate and the maximum concentration of atrazine in the output curve compared to the experimental data.

  7. Return Migration as Failure or Success?: The Determinants of Return Migration Intentions Among Moroccan Migrants in Europe.

    Science.gov (United States)

    de Haas, Hein; Fokkema, Tineke; Fihri, Mohamed Fassi

    Different migration theories generate competing hypotheses with regard to determinants of return migration. While neoclassical migration theory associates migration to the failure to integrate at the destination, the new economics of labour migration sees return migration as the logical stage after migrants have earned sufficient assets and knowledge and to invest in their origin countries. The projected return is then likely to be postponed for sustained or indefinite periods if integration is unsuccessful. So, from an indication or result of integration failure return is rather seen as a measure of success. Drawing on recent survey data ( N  = 2,832), this article tests these hypotheses by examining the main determinants of return intention among Moroccan migrants across Europe. The results indicate that structural integration through labour market participation, education and the maintenance of economic and social ties with receiving countries do not significantly affect return intentions. At the same time, investments and social ties to Morocco are positively related, and socio-cultural integration in receiving countries is negatively related to return migration intentions. The mixed results corroborate the idea that there is no uniform process of (return) migration and that competing theories might therefore be partly complementary.

  8. Developing evidence-based ethical policies on the migration of health workers: conceptual and practical challenges

    2003-10-01

    Full Text Available Abstract It is estimated that in 2000 almost 175 million people, or 2.9% of the world's population, were living outside their country of birth, compared to 100 million, or 1.8% of the total population, in 1995. As the global labour market strengthens, it is increasingly highly skilled professionals who are migrating. Medical practitioners and nurses represent a small proportion of highly skilled workers who migrate, but the loss of health human resources for developing countries can mean that the capacity of the health system to deliver health care equitably is compromised. However, data to support claims on both the extent and the impact of migration in developing countries is patchy and often anecdotal, based on limited databases with highly inconsistent categories of education and skills. The aim of this paper is to examine some key issues related to the international migration of health workers in order to better understand its impact and to find entry points to developing policy options with which migration can be managed. The paper is divided into six sections. In the first, the different types of migration are reviewed. Some global trends are depicted in the second section. Scarcity of data on health worker migration is one major challenge and this is addressed in section three, which reviews and discusses different data sources. The consequences of health worker migration and the financial flows associated with it are presented in section four and five, respectively. To illustrate the main issues addressed in the previous sections, a case study based mainly on the United Kingdom is presented in section six. This section includes a discussion on policies and ends by addressing the policy options from a broader perspective.

    This study aims to investigate the determinants factors that effect the dividend policy. The sample used in this research is manufacture companies listed in Indonesia Stock Exchange (IDX) and the period 2011 - 2015. There are independent variables such as earning, cash flow, free cash flow, debt, growth opportunities, investment opportunities, firm size, largest shareholder, firm risk, lagged dividend and dividend policy used as dependent variable. The study examines a total of 32 manufacture companies. After analyzing the data using the program software Eviews 9.0 by multiples regression analysis reveal that earning, cash flow, free cash flow, firm size, and lagged dividend have significant effect on dividend policy, whereas debt, growth opportunities, investment opportunities, largest shareholder, and firm risk have no significant effect on dividend policy. The results of this study are expected to be implemented by the financial managers in improving corporate profits and basic information as return on investment decisions.

    Migratory decisions in birds are closely tied to environmental cues and fat stores, but it remains unknown if the same variables trigger bat migration. To learn more about the rare phenomenon of bat migration, we studied departure decisions of female common noctules ( Nyctalus noctula ) in southern Germany. We did not find the fattening period that modulates departure decisions in birds. Female noctules departed after a regular evening foraging session, uniformly heading northeast. As the day of year increased, migratory decisions were based on the interactions among wind speed, wind direction and air pressure. As the migration season progressed, bats were likely to migrate on nights with higher air pressure and faster tail winds in the direction of travel, and also show high probability of migration on low-pressure nights with slow head winds. Common noctules thus monitor complex environmental conditions to find the optimal migration night. © 2017 The Authors.

  15. Changes in Cuba’s Migration Policy and Its Impact on Baseball

    Onesimo Julian Moreira Seijos

    2014-11-01

    Full Text Available Baseball is an essential constituent of the Cuban national identity. For nearly a century, Cuban baseball players had joined high-ranking international leagues, including the Negro Leagues and Major League Baseball (MLB of the United States. After the triumph of the Revolution in 1959, the professional practice of sport was banned in the country. On the other hand, the revolutionary government instituted migration rules that disallowed Cuban citizens to travel abroad freely. Until the collapse of the Soviet Union, the Cuban national baseball team reigned in amateur competitions worldwide. Sporting successes in general and those of baseball in particular, were managed by the government as a political tool; the government used to display the loyalty of the athletes as a triumph of the Cuban system. However, since the nineties there has been a growing departure of Cuban top baseball players who have had the target of entering in MLB franchises, disregarding that the Cuban migration policy had remained unwavering. On the other hand, after the enactment of changes in the Cuban migration policy in 2013, the unconventional departure of high performance baseball players has increased sharply. The relationship between the migration reform and the increased leakage of baseball players has not been studied by scholars. The relevance of this paper is that it is the first academic approach to that relationship. This paper discusses the migration reform in Cuba and focuses mainly on its impact on baseball.

  16. Labor migration, externalities and ethics: theorizing the meso-level determinants of HIV vulnerability.

    Science.gov (United States)

    Hirsch, Jennifer S

    2014-01-01

    This paper discusses labor migration as an example of how focusing on the meso-level highlights the social processes through which structural factors produce HIV risk. Situating that argument in relation to existing work on economic organization and HIV risk as well as research on labor migration and HIV vulnerabilities, the paper demonstrates how analyzing the processes through which labor migration creates vulnerability can shift attention away from the proximate behavioral determinants of HIV risk and toward the community and policy levels. Further, it presents the concepts of externalities and the ethics of consumption, which underline how both producers and consumers benefit from low-waged migrant labor, and thus are responsible for the externalization of HIV risk characteristic of supply chains that rely on migrant labor. These concepts point to strategies through which researchers and advocates could press the public and private sectors to improve the conditions in which migrants live and work, with implications for HIV as well as other health outcomes.

  17. [Argentine migration policy and movements of the European population (1876-1925)].

    Devoto, F J

    1989-04-01

    This work examines changes in Argentine migration policy from 1876-1925 and the relationship between public policy and population movements. Promoting immigration from Europe as proposed in article 25 of the Argentine constitution of 1853 was 1 of the most enduring objectives of Argentina's leadership. When Law of Immigration and Colonization (Law 817) was passed by the Chamber of Senators in 1876, the flow of immigration was at its lowest point in 8 years. Many of the provisions of Law 817 had already been put into practice occasionally or systematically, but the intent to use the law to attract a far greater number of immigrants and to select qualities seen as desirable were novel elements and the principal motives of the legislation. The unstated aim of reducing the preponderance of Italian immigration from about 2/3 was not immediately achieved. Argentina's immigration policy and actions were in competition with those of other Latin American countries and with the US. Information offices for prospective immigrants were opened in the 1880s in Paris, London, Brussels, Berlin, Vienna, Bern, and New York, and in 1887 legislation was passed permitting subsidized passages on a large scale. The continued predominance of Italian immigration demonstrated the limits of government policy influence, even when large sums of money were invested. The informal network of Italian immigrants already in Argentina and the activities of interested shipping companies on the other hand played major roles in maintaining Italian immigration. The total number of immigrants and the diversity of national origins were increased by the subsidized passages, but in 1891 the combination of a financial crisis and an end to subsidized passages decisively reduced the total flow. Changes occurred in the 1890s in regional flows within countries and in the occupational composition of immigrants from agricultors to day laborers, unskilled workers, and artisans. By about 1910 the conservative elements

  18. Harmonisation of European Migration Policies: The Failure of Immigration Control Policies in the Seventh and Eighth Decades of the 20th Century

    Directory of Open Access Journals (Sweden)

    Milan Mesić

    2003-12-01

    Full Text Available Until the middle of the 1970s, the migration policies of developed European countries were based on the assumption that controlling immigration was possible. Due to various reasons discussed in this article, such policies proved unsuccessful. The result was an increase in the total number of foreigners and a change in the composition of immigrant communities, i.e. the proportion of supported family members increased. During the 1980s there was increasing convergence in the migration policies of European immigration countries and traditional overseas emigration countries. Policies were more and more oriented towards preventing illegal migration flows, on regulating refugee flows and on balancing labour migration with family migration. The turning-point in the direction of “harmonising” West European migration policies was marked by the Schengen agreement (1985 on gradual elimination of border controls between the signing parties (France, Germany and the Benelux countries. Fear in the face of a possible invasion of Eastern Europeans after the collapse of socialism in 1989 was a further strong stimulus towards the harmonisation of migration policies in the developing EU. As opposed to migration control, the integration of immigrants has remained so far the prerogative of nation-states. The text further presents an overview of migration policy reforms in individual member states of the EU and of multilateral actions. The post-1989 migration regime in Europe has four major traits: 1 an extension of the agenda; 2 an accent on joint actions; 3 defensiveness; 4 confusion and an overload of issues. While on the one hand the EU continues to seek ways of protecting itself from undesired external migration, on the other hand the process of regional integration continues to “erase” its internal borders.

It also investigates if the income attraction of locations varies with recency of labor market experience. Welfare gains increase the probability of interstate migration. Welfare effects are largest for single mothers with small children and stronger among women with no recent labor market experience. The welfare effects, albeit small, are larger than the wage effects. The wage effects are weaker among women with no recent work experience. Ethnic-specific analyses suggest differences in migration behavior among Anglos, African-Americans, and Puerto Ricans." excerpt

    2017-01-01

    Family migration policy, once basing citizens and resident foreigners' possibilities to bring in foreign family members mainly on the right to family life, is increasingly a tool states use to limit immigration and to push newcomers to integrate into civic and economic life. The family migration policies of Denmark, Norway and Sweden range widely - from more minimal support and age requirements to high expectations of language skills, work records and even income levels. While in Denmark and increasingly in Norway growing sets of requirements have been justified on the need to protect the welfare state and a Nordic liberal way of life, in Sweden more minimal requirements have been introduced in the name of spurring immigrants' labor market integration even as rights-based reasoning has continued to dominate. In all three countries, new restrictions have been introduced in the wake of the refugee crisis. These cases show how prioritizations of the right to family life vis-à-vis welfare-state sustainability have produced different rules for family entry, and how family migration policies are used to different extents to push civic integration of both new and already settled immigrants.

  4. DETERMINATION OF OBJECTIVES FOR URBAN FREIGHT POLICY

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Background: Decisions regarding strategic planning of urban freight transport very often are based on superficial assumptions inadequately reflecting the actual character of encountered challenges. The trend may be observed to adapt isolated solutions without supporting measures and verification of expected outcomes. Selected urban freight solutions have a significant potential to alleviate transport related problems, but they require unorthodox approach beyond standard traffic planning and road management. City's current planning experience must be taken into account to plan an optimized sequence of actions. Method: Due to complexity of the problem and specific decision making factors the analytic network process ANP was selected to determine relevant objective of the urban freight policy. Gdynia was selected as the subject for modeling with a review of the current freight planning practice as a first step. Then, classification of policy objective and their prerequisites were identified supported with descriptive feasibility assessment. This allowed for a development of the ANP decision-making model. Results: Considered objectives for urban freight policy were identified were optimization, reduction and transfer. After verifying relevant decision factors optimization was selected as the most feasible option for Gdynia. Other alternatives were rated around four times lower with a slight prevalence of reduction over transfer. Such ranking reflects current planning practice and availability of transferable experiences. Despite the indicative results, it must be stressed that urban freight planning should be based on the long term methodical approach not to exclude any emerging possibilities.

It utilizes cross-sectional data generated from a national sample survey of internal migration conducted...between January and March 1988.... The empirical results revealed that the significant determinants of rural-urban migration in Nigeria are income, contact, cost, spoken English, ability to speak two Nigerian languages, distance, marital status, sex and ethnicity. The results further suggest that rural-urban migration is selective of single people and males. Proximity to urban areas where prospective migrants have relatives, friends and townspeople is an important factor." excerpt

    Green cloud data center has become a research hotspot of virtualized cloud computing architecture. Since live virtual machine (VM) migration technology is widely used and studied in cloud computing, we have focused on the VM placement selection of live migration for power saving. We present a novel heuristic approach which is called PS-ABC. Its algorithm includes two parts. One is that it combines the artificial bee colony (ABC) idea with the uniform random initialization idea, the binary search idea, and Boltzmann selection policy to achieve an improved ABC-based approach with better global exploration's ability and local exploitation's ability. The other one is that it uses the Bayes theorem to further optimize the improved ABC-based process to faster get the final optimal solution. As a result, the whole approach achieves a longer-term efficient optimization for power saving. The experimental results demonstrate that PS-ABC evidently reduces the total incremental power consumption and better protects the performance of VM running and migrating compared with the existing research. It makes the result of live VM migration more high-effective and meaningful.

  11. The determination of optimal climate policy

    Analyses of the costs and benefits of climate policy, such as the Stern Review, evaluate alternative strategies to reduce greenhouse gas emissions by requiring that the cost of emission cuts in each and every year has to be covered by the associated value of avoided damage, discounted by a an exogenously chosen rate. An alternative is to optimize abatement programmes towards a stationary state, where the concentrations of greenhouse gases are stabilized and shadow prices, including the rate of discount, are determined endogenously. This paper examines the properties of optimized stabilization. It turns out that the implications for the evaluation of climate policy are substantial if compared with evaluations of the present value of costs and benefits based on exogenously chosen shadow prices. Comparisons of discounted costs and benefits tend to exaggerate the importance of the choice of discount rate, while ignoring the importance of future abatement costs, which turns out to be essential for the optimal abatement path. Numerical examples suggest that early action may be more beneficial than indicated by comparisons of costs and benefits discounted by a rate chosen on the basis of current observations. (author)

  12. The causes of international labor migrations--a demand-determined approach.

    The author first studies the reasons why people migrate using a neoclassical approach concerning income differentials. He tests this approach empirically and demonstrates its limits. A demand-determination approach based on human capital theory is then outlined to overcome these limits and to take into account restrictive immigration controls. Migration from Italy, Spain, Greece, Portugal, and Turkey to the European Community destination countries is examined. It is concluded that "the demand for immigrants in the destination country is the decisive condition for the phenomenon of international labor migration, and the supply of migration-willing workers is only a necessary condition." excerpt

  13. Through the back door: nurse migration to the UK from Malawi and Nepal, a policy critique.

    The UK National Health Service has a long history of recruiting overseas nurses to meet nursing shortages in the UK. However, recruitment patterns regularly fluctuate in response to political and economic changes. Typically, the UK government gives little consideration of how these unstable recruitment practices affect overseas nurses. In this article, we present findings from two independent research studies from Malawi and Nepal, which aimed to examine how overseas nurses encountered and overcame the challenges linked to recent recruitment and migration restrictions. We show how current UK immigration policy has had a negative impact on overseas nurses' lives. It has led them to explore alternative entry routes into the UK, affecting both the quality of their working lives and their future decisions about whether to stay or return to their home country. We conclude that the shifting forces of nursing workforce demand and supply, leading to abrupt policy changes, have significant implications on overseas nurses' lives, and can leave nurses 'trapped' in the UK. We make recommendations for UK policy-makers to work with key stakeholders in nurse-sending countries to minimize the negative consequences of unstable nurse recruitment, and we highlight the benefits of promoting circular migration.

  15. The Social Determinants of Refugee Mental Health in the Post-Migration Context: A Critical Review.

    2018-05-01

    With the global increase in the number of refugees and asylum seekers, mental health professionals have become more aware of the need to understand and respond to the mental health needs of forced migrants. This critical review summarizes the findings of recent systematic reviews and primary research on the impact of post-migration conditions on mental disorders and PTSD among refugees and asylum seekers. Historically, the focus of mental health research and interventions with these populations has been on the impact of pre-migration trauma. Pre-migration trauma does predict mental disorders and PTSD, but the post-migration context can be an equally powerful determinant of mental health. Moreover, post-migration factors may moderate the ability of refugees to recover from pre-migration trauma. The importance of post-migration stressors to refugee mental health suggests the need for therapeutic interventions with psychosocial elements that address the broader conditions of refugee and asylum seekers' lives. However, there are few studies of multimodal interventions with refugees, and even fewer with control conditions that allow for conclusions about their effectiveness. These findings are interpreted using a social determinants of health framework that connects the risk and protective factors in the material and social conditions of refugees' post-migration lives to broader social, economic and political factors.

    International migration to middle-income countries is increasing and its health consequences, in particular increasing transmission rates of tuberculosis (TB), deserve consideration. Migration and TB are a matter of concern in high-income countries and targeted screening of migrants for active and latent TB infection is a main strategy to manage risk and minimize transmission. In this paper, we discuss some aspects of TB control and migration in the context of middle-income countries, together with the prospect of responding with equitable and comprehensive policies. TB rates in middle-income countries remain disproportionally high among the poorest and most vulnerable groups in large cities where most migrant populations are concentrated. Policies that tackle migrant TB in high-income countries may be inadequate for middle-income countries because of their different socio-economic and cultural scenarios. Strategies to control TB in these settings must take into account the characteristics of middle-income countries and the complexity of TB as a disease of poverty. Intersectoral policies of social protection such as cash-transfer programs help reducing poverty and improving health in vulnerable populations. We address the development of new approaches to improve well-established strategies including contact tracing and active and latent TB screening as an 'add on' to the existing health care guidelines of conditional cash transfer programs. In addition, we discuss how it might improve health and welfare among both poor migrants and locally-born populations. Authorities from middle-income countries should recognise that migrants are a vulnerable social group and promote cooperation efforts between sending and receiving countries for mitigation of poverty and prevention of disease in this group. Middle-income countries have long sent migrants overseas. However, the influx of large migrant populations into their societies is relatively new and a growing phenomenon and

    2015-12-01

    Full Text Available This article examines how the recent evolution of asylum migration has affected the construction of the European Common Foreign and Security Policy (EU-CFSP, taking the Greek case during the 2001-2012 period as a starting point. With this in mind, the normative progress of the EU-CFSP facing the reception of asylum seekers in Greece is analyzed, under the scope of what Barry Buzan and Ole Waever would call Securitization Process. Both legal and political frameworks on asylum migration in Greece and in the European Union are approached, in the context of the evolution of the EU-CFSP in three main areas: Neighborhood Policy, Development and Cooperation Policy, and Human Rights Protection. The conclusión points toward the partial influence of asylum migration in the configuration of the UE-CFSP during the studied period.

  1. Impact of policies regulating foreign physician migration to Switzerland: a modelling case study in anaesthesia.

    Several countries have developed policies that restrict or limit duration of stay, clinical privileges or the number of residency permits allocated to migrating physicians. Switzerland is currently preparing a new law limiting overall foreign immigration. The impact of such restrictive policies is currently unknown. In a case study of anaesthesia care in Switzerland we modelled, trends in the size of physicians' workforce until 2024, following the implementation of a strict quota policy for foreign medical trainees. We developed a computer-based Markov model with Monte-Carlo simulations to project, in the context of a strict quota policy for foreign trainees, supply and demand for anaesthesia positions until 2024. We used data from a cross-sectional study performed in the French- and Italian-speaking cantons of Switzerland and the Health dataset from the OECD. With 8 to 12 (95% CI 4-20) anaesthetists retiring per year, the implementation of strict quotas of foreign graduates would result in a 38% decrease in the number of anaesthetists in intermediary (senior registrars) positions by 2024. This decrease would be particularly important in district hospitals where nearly half (49%) of the non-Swiss anaesthetists are practising. Swiss graduates are unlikely to balance the shortage. Despite efforts by Swiss universities to increase the number of medical graduates, their number has dropped from 10.5 to 9.7/100 000 inhabitants between 2000 and 2012, due to the growth of the population. This case study in Latin Switzerland shows that a restrictive policy limiting foreign immigration of trainees would result in a major deficit in the number of anaesthetists available to meet population needs. These aspects should be carefully considered when countries develop restrictions and limitations of foreign immigration.

    Full Text Available Published by Palgrave MacmillanFocusing on India and China, two countries with high levels of emigration that have developed policies aimed at promoting ties with their nationals who live abroad, this article contributes to the academic and political debate about the relationships between the phenomenon of migration and the development of migrants’ countries of origin. In light of the measures that both these countries have amassed for the benefit of their overseas communities, one can identify the need to create one or more institutional structures to promote individual initiatives. The importance of reciprocity is emphasised, which is an essential aspect of relations between the government of the country of origin and its migrants.

  4. Sociopolitical determinants of international health policy.

    De Vos, Pol; Van der Stuyft, Patrick

    2015-01-01

    For decades, two opposing logics have dominated the health policy debate: a comprehensive health care approach, with the 1978 Alma Ata Declaration as its cornerstone, and a private competition logic, emphasizing the role of the private sector. We present this debate and its influence on international health policies in the context of changing global economic and sociopolitical power relations in the second half of the last century. The neoliberal approach is illustrated with Chile's health sector reform in the 1980s and the Colombian reform since 1993. The comprehensive "public logic" is shown through the social insurance models in Costa Rica and in Brazil and through the national public health systems in Cuba since 1959 and in Nicaragua during the 1980s. These experiences emphasize that health care systems do not naturally gravitate toward greater fairness and efficiency, but require deliberate policy decisions. © The Author(s) 2015 Reprints and permissions:]br]sagepub.co.uk/journalsPermissions.nav.

    Full Text Available Migration is a very important socio‑economic issue in the contemporary world. One of the interesting and pertinent research problems worth considering concerns the scale and nature of migration from countries which entered the European Union in 2004 and in the subsequent years. As a result of integration within the European Community, the citizens of member states acquired citizenship within the entire European Union (which is complementary to citizenship in the country of origin. The right of free movement led to the emergence of the migration phenomenon within the territory of the European Union. A well educated and young labour force may be an influential factor in the social and economic development of the European Union members. The enlargement of the EU led to a significant increase in the number of part‑time/temporary migrants. According to statistical data, the number of emigrants from the Central and Eastern European Countries (CEE to the more prosperous European countries increased from 1,66 million in 2004 to 7,3 million in 2016. Within the context of the scale of economic migration from the CEE, questions should be asked about the determinants and economic consequences of this mobility. The main objective of this article is a diagnosis and evaluation of the determinants and size of migration from the CEE. The analyses are based on Eurostat data. The determinants of migration are presented from the point of view of the push and pull factors theory and related to the situation in the European labour market. An analysis of the size of migration outflow from the CEE countries made it possible to classify them into three groups: countries with a high emigration potential (Latvia, Lithuania, Romania, a moderate emigration potential (Hungary, Bulgaria, Poland, Estonia, Slovakia and a low emigration potential (the Czech Republic, Slovenia. The economic consequences of migration are shown from the perspective of remittances received from

    The rise in migration for employment since the mid-1970s has had serious consequences for many Asian countries. This discussion examines the issues raised by the migration abroad of thousands of skilled workers and the efforts that sending countries have made in recent years to bring the effects of labor migration more closely into line with their development objectives. It also considers several problem areas requiring the attention of policymakers and authorities responsible for the administration of overseas employment policies. It is estimated that between 1976-81 annual labor migrant flows from the 8 major sending countries in Asia increased sevenfold, from a mere 146,400 to over 1 million. The Asian migrant workers tend to be young, male, married (with dependents in the sending country), and better educated than the average home population. Most of them come from rural areas and are predominantly employed in construction and labor. The most distinctive feature of these workers is their concentration in a few blue collar occupations--carpenters, masons, electricians, plumbers, lorry drivers, mechanics, and heavy equipment operators. These production and trnasport workers outnumber the professional and technical workers by anywhere from 3 to 1 (Philippines) to 17 to 1 (Pakistan and Sri Lanka). At the aggregate level labor emigration affects the sending country's economy through its impact on the labor market, on the financial market, and on the market for goods and services. It can be argued that the outflow of a significant proportion of the labor force should lead directly to a rise in labor projectivity in the sending country since capital per worker among those left behind will increase, yet it can also be argued that since migration sifts out the most skilled and experienced workers there will be an erosion of the country's human captial resources. Specific measures have been adopted in most labor sending Asian countries to protect the welfare of migrant

  9. Determinants of Romanians' Migration within the European Union: Static and Dynamic Panel Gravity Approaches

    Full Text Available The 1st of January 2007 marked Romania’s accession to the European Union (EU and represented its 'ticket' to a free access to the common market. This soon evolved into an important trigger for the increased migration flows from Romania towards the more developed western countries, members of the EU. Not only the opportunity of a free movement of persons – emerged with the integration - but also the existing socio-economic disparities between Romania and the more developed western countries in the EU, led to unidirectional migration flows. Using both static and dynamic panel gravity models, we aim to identify the main determinants of Romanians' migration towards 10 EU member states – Czech Republic, Denmark, Italy, Netherlands, Finland, Germany, Norway, Poland, Spain, and Sweden – for the period 2007-2014. Our empirical findings support the results of other studies performed on different economies. The most important pull factor for Romanians' migration is represented by the economic conditions in the destination countries, proxied by the GDP/capita. Other important pull factors fuelling Romanians' migration refer to the unemployment rate, life expectancy, education spending, and population density. A key role is also played by the existing social networks in the destination countries which are proxied in our model by the lagged migration flows

    Since 1973 the increase in revenues from petroleum has resulted in a substantial migration of workers to the oil exporting countries of the Middle East. Discussion focuses on the policies being used to minimize the costs and maximize the advantages of emigration, including description and evaluation of measures and proposals for further action. No action seems to have been taken to regulate the present wave of Middle Eastern emigration, probably because in its initial stages it proved an unmixed blessing for the labor exporting countries. Steps should have been taken to protect the emigrants. Their living conditions are unsatisfactory in some host countries, and frequently they are exploited by the unscrupulous middlemen who arranged their employment and wages. No effective international agreements, multilateral or bilateral, have been concluded to deal with these problems. A policy response is required as labor shortages emerge in the later phases of emigration, especially as the balance of payments situation improves and reserves rise. An appropriate strategy should combine both supply and demand management measures. It should avoid overambitious antiinflationary objectives. For the majority of the labor exporting countries discussed here, foreign exchange earnings from migrants have reached sizable amounts, exceeding, for example, $1 billion in Egypt, India, Pakistan, and the Yemen Arab Republic. Countries are maximizing those receipts by resorting to compulsion and surrender requirements. Emigrants should be coaxed and not compelled to remit currently a high proportion of savings and to invest a low percentage in the country where they work or in 3rd countries. Remittances by workers during the period of their stay in foreign countries are made for family maintenance and for investment. The most effective way to satisfy emigrants that they will be able to reexport their assets is to remove all restrictions on payments. Going beyond general policies to create a

    Migrants occupy a significant proportion of the dental workforce in Australia. The objectives of this study were to assess the level of job satisfaction of employed migrant dentists in Australia, and to examine the association between various migrant dentist characteristics and job satisfaction. All migrant dentists resident in Australia were surveyed using a five-point Likert scale that measured specific aspects of job, career and satisfaction with area and type of practice. A total of 1022 migrant dentists responded to this study; 974 (95.4%) were employed. Responses for all scales were skewed towards strongly agree (scores ≥4). The overall scale varied by age group, marital status, years since arrival to Australia and specialist qualification (chi-square, p satisfaction amongst older age groups. Dentists who migrated through the examination pathway (mainly from low- and middle-income countries) had a lower probability of being satisfied with the area and type of practice (OR = 0.71; 0.51-0.98), compared with direct-entry migrant dentists (from high-income countries). The high level of job satisfaction of migrant dentists reflects well on their work-related experiences in Australia. The study offers policy suggestions towards support for younger dentists and examination pathway migrants, so they have appropriate skills and standards to fit the Australian health care environment. © 2016 Australian Dental Association.

    2013-04-01

    Full Text Available The main goal of this article is to provide a good basis to assess the way media frames are embedded in a wider social scenario, and how public and political preferences can be researched through media debate. The methodology adopted allows for an analysis of newspaper articles that can show broader trends of the debate and serve as a thermometer to measure public debate. It can further highlight details and enable in-depth analyses of media discourse. The article explores the interconnectedness of media debate and policy-making process by means of the analysis of articles published in a Brazilian newspaper between 2009 and 2010. Quantitative and qualitative methodologies are employed to identify the frames used in media and to offer insights of their relationship with the political debate. The ongoing political debate has raised attention to the issue of migration, with a great numbers of actors expressing very diverse points of view. A broader public debate has been initiated and some portions of it find voice in different means of communication. The paper argues that changes in the public and in the media debate are a response to changes in the political debate, while at the same time the first two also help to outline the latter.

    The particle size and heaped methods of exhalation media have important effects on physical parameters, such as the free radon production rate, porosity, permeability, and radon diffusion coefficient. However, existing methods for determining those parameters are too complex, and time-consuming. In this study, a novel, systematic determining method was proposed based on nuclide decay, radon diffusion migration theory, and the mass conservation law, and an associated experimental device was designed and manufactured. The parameters of uranium ore heap and sandy soil of radon diffusion coefficient (D), free radon production rate (α), media permeability (k), and porosity (ε) were obtained. At the same time, the practicality of the novel determining method was improved over other methods, with the results showing that accuracy was within the acceptable range of experimental error. This novel method will be of significance for the study of radon migration and exhalation in granulated porous media. Copyright © 2017 Elsevier Ltd. All rights reserved.

    García-Ramírez, Jorge A; Vélez-Álvarez, Consuelo

    2013-01-01

    The study was aimed at identifying Latin-American countries' public policy which has been related to the social determinants of health. A topic review was thus made of papers kept in the 22 Latin-American countries' databases and official documents issued by their multilateral organisations and ministries of health. The World Health Organization's concept of the social determinants of health has been summarised and a history given of the pertinent work developed worldwide in regions such as Europe and Latin-America. Public policy regarding the field of study in Argentina, Brazil, Bolivia, Chile, Colombia, Costa Rica, México and Venezuela has been described. It was concluded that Latin-America provides a panorama of inequality regarding the application of policy concerning the social determinants of health and that there was segmented intervention, mainly regarding intermediate determinants of health, without taking an integrated approach from different entrance points into account, according to the stated conceptual framework.

    Collective cell migration contributes to embryogenesis, wound healing and tumour metastasis. Cell monolayer migration experiments help in understanding what determines the movement of cells far from the leading edge. Inhibiting cell proliferation limits cell density increase and prevents jamming; we observe long-duration migration and quantify space-time characteristics of the velocity profile over large length scales and time scales. Velocity waves propagate backwards and their frequency depends only on cell density at the moving front. Both cell average velocity and wave velocity increase linearly with the cell effective radius regardless of the distance to the front. Inhibiting lamellipodia decreases cell velocity while waves either disappear or have a lower frequency. Our model combines conservation laws, monolayer mechanical properties and a phenomenological coupling between strain and polarity: advancing cells pull on their followers, which then become polarized. With reasonable values of parameters, this model agrees with several of our experimental observations. Together, our experiments and model disantangle the respective contributions of active velocity and of proliferation in monolayer migration, explain how cells maintain their polarity far from the moving front, and highlight the importance of strain-polarity coupling and density in long-range information propagation.

    1986-07-01

    A computer code (MIGSTEM-FIT) has been developed to determine the prediction parameters, retardation factor, water flow velocity, dispersion coefficient, etc., of radionuclide migration in soil layer from the concentration distribution of radionuclide in soil layer or in effluent. In this code, the solution of the predicting equation for radionuclide migration is compared with the concentration distribution measured, and the most adequate values of parameter can be determined by the flexible tolerance method. The validity of finite differential method, which was one of the method to solve the predicting equation, was confirmed by comparison with the analytical solution, and also the validity of fitting method was confirmed by the fitting of the concentration distribution calculated from known parameters. From the examination about the error, it was found that the error of the parameter obtained by using this code was smaller than that of the concentration distribution measured. (author)

    Full Text Available The paper explores the determinants of internal migration in Albania, adopting the Harris-Todaro approach to migration: an internal migration function is estimated using district wage and unemployment rate differentials. The aggregate level wages and unemployment, included in the migration equation, are retrieved from a first stage wage and unemployment equations, estimated controlling for personal characteristics. Moreover, in order to test the predictions of the human capital model of migration, the difference between migrants and non-migrants is emphasized in the estimation. The data source is the "Living Standard Measurement Survey for Albania" (2002, undertaken by the national Institute of Statistics and the World Bank jointly. The results reveal that both wage and unemployment differentials are important determinants of the propensity to migrate in Albania. This conclusion is further emphasized by noting that migrants gain substantially in terms of higher returns to individual characteristics after emigration.

  1. India and Iran's nuclear issue: the three policy determinants

    International Nuclear Information System (INIS)

    Rajiv, S. Samuel C.

    2011-01-01

    Three broad policy determinants can be discerned in Indian reactions to the Iranian nuclear issue. These include: 'strategic autonomy' as it relates to Indian foreign policy decision making; concerns regarding 'regional strategic stability' as it relates to events in its 'proximate neighbourhood'; and 'national security' implications on account of operative clandestine proliferation networks. Issues relating to the role of the US in influencing Indian policy positions at international forums and vis-a-vis domestic policy were prominent as regards the first determinant. Threats and 'advice' by American policy makers and law makers on specific issues like the Indo-US nuclear deal and the Iran-Pakistan-India gas pipeline gave further grist to critics. However, an analysis of India's concerns regarding the other two policy considerations, i.e., strategic stability and national security were 'real and present' and also dominated public discourse as well. With India having become a non-permanent member of the UN Security Council from January 2011, it should be the task of Indian diplomacy, at the UNSC as well as at other bilateral and multilateral settings, to help expand the space for the application of 'satisfactory strategies' and reduce the range of 'unsatisfactory strategies'.

    Migration studies were conducted to determine the quantity of styrene that migrates from polymers into fatty foods, specifically margarine. Azeotropic distillation was used to isolate styrene from the margarine. Headspace gas chromatography with a Chromosorb 104 column and a flame ionization detector was used for quantitation. The quantitation limit for the method was about 25 ppb (wt/wt) styrene in margarine. On the average, greater than 90% of the styrene was recovered. Several commercial margarines were examined. The method and results of the migration studies are presented. There was no detectable migration of styrene into margarine.

It finds that investment variables are more important than the conventional variables of income and job opportunities in determining China's recent interregional migration. It suggests that both state policy and the global force influence interregional migration, challenging the popular view that the socialist state is the only critical determinant. This paper also criticizes Mao's approach to interregional migration and discusses the impact of migration on development." excerpt

    2011-01-01

    Factors affecting winter survival may be key determinants of status and population trends of seabirds, but connections between breeding sites and wintering areas of most populations are poorly known. Pelagic Cormorants (Phalacrocorax pelagicus; N= 6) surgically implanted with satellite transmitters migrated from a breeding colony on Middleton Island, northern Gulf of Alaska, to wintering sites in southeast Alaska and northern British Columbia. Winter locations averaged 920 km (range = 600-1190 km) from the breeding site. Migration flights in fall and spring lasted ???5 d in four instances. After reaching wintering areas, cormorants settled in narrowly circumscribed inshore locations (~10-km radius) and remained there throughout the nonbreeding period (September- March). Two juveniles tagged at the breeding colony as fledglings remained at their wintering sites for the duration of the tracking interval (14 and 22 mo, respectively). Most cormorants used multiple sites within their winter ranges for roosting and foraging. Band recoveries show that Pelagic Cormorants in southern British Columbia and Washington disperse locally in winter, rather than migrating like the cormorants in our study. Radio-tagging and monitoring cormorants and other seabirds from known breeding sites are vital for understanding migratory connectivity and improving conservation strategies for local populations. ?? 2011 The Authors.

    The long-term migration of 99 Tc (213,000-yr half-life) must be considered when examining the disposal of spent nuclear fuel in a geologic repository. This report outlines an investigation of the effects of iron, tin, stannous chloride, copper, manganese, and vanadium as reactants added to a mixture of technetium and J-13 well water to cause technetium precipitation. The J-13 well water was chosen because it is representative of the groundwater located at Yucca Mountain. A state-of-the-art computer software package, EQ3/6, was developed at Lawrence Livermore National Laboratory and was utilized in this study to project the result when metallic iron, tin, copper, manganese, and vanadium and the compound stannous chloride are individually added to a mixture of metallic technetium and J-13 well water. The computer codes in this study indicate that the problems associated with technetium migration at the federal repository are not insurmountable if a reactant capable of producing reducing conditions to the incoming groundwater is integrated into the waste package. Further work will focus on the laboratory experimentation to validate the computer results and to determine the best materials and configurations to inhibit technetium migration at the repository

    Full Text Available In recent years, the phenomenon of migration has intensified throughout the country, an increasing number of people choosing the path of foreign countries in the hope of a better life. It becomes a challenge for general managers in firms to retain those employees who have the skills needed to perform at a high level of performance the duties regarding work. The research conducted in this paper is a qualitative one, trying to provide an answer to the question stated in the title, ie if the current salary level practiced in Romania is a motivational factor for providing a valuable work, or on the contrary, is an element that lies at the basis of migration. The first part of the paper presents a theoretical point of view, presenting general aspects regarding the current economic context in terms of staff motivation, but also the general perspectives referring to the issue of migration. The final part presents a study that uses the focus group method in order to determine whether the young people in Caras Severin are susceptible to leaving the country for a higher wage level or would they consider this aspect for the following period of time.

    2001-01-01

    Satellite telemetry was used to determine fall migratory movements of Ospreys (Pandion haliaetus) breeding in the United States. Study areas were established along the lower Columbia River between Oregon and Washington; in north-central Minnesota; on Shelter Island, New York; and in southern New Jersey. Seventy-four adults (25 males, 49 females) were tracked from 1995 through 1999. Migration routes differed among populations but not by sex. Western Ospreys migrated through California and to a lesser degree other western states and wintered in Mexico (88%), El Salvador (6%), and Honduras (6%) (25.9A?N to 13.0A?N and 108.3A?W to 87.3A?W). Minnesota Ospreys migrated along three routes: (1) through the Central U.S. and then along the east coast of Mexico, (2) along the Mississippi River Valley, then across the Gulf of Mexico, or (3) through the southeastern U.S., then across the Caribbean. East Coast birds migrated along the eastern seaboard of the U.S., through Florida, and across the Caribbean. Midwestern birds wintered from Mexico south to Bolivia (22.35A?N to 13.64A?S, and 91.75A?W to 61.76A?W), while East Coast birds wintered from Florida to as far south as Brazil (27.48A?N to 18.5A?S and 80.4A?W to 57.29A?W). Dates of departure from breeding areas differed significantly between sexes and geographic regions, with females leaving earlier than males. Western birds traveled a shorter distance than either midwestern or eastern Ospreys. Females traveled farther than males from the same population, which resulted in females typically wintering south of males.

  14. Small heat shock proteins are necessary for heart migration and laterality determination in zebrafish

    Small heat shock proteins (sHsps) regulate cellular functions not only under stress, but also during normal development, when they are expressed in organ-specific patterns. Here we demonstrate that two small heat shock proteins expressed in embryonic zebrafish heart, hspb7 and hspb12, have roles in the development of left-right asymmetry. In zebrafish, laterality is determined by the motility of cilia in Kupffer’s vesicle (KV), where hspb7 is expressed; knockdown of hspb7 causes laterality defects by disrupting the motility of these cilia. In embryos with reduced hspb7, the axonemes of KV cilia have a 9+0 structure, while control embyros have a predominately 9+2 structure. Reduction of either hspb7 or hspb12 alters the expression pattern of genes that propagate the signals that establish left-right asymmetry: the nodal-related gene southpaw (spaw) in the lateral plate mesoderm, and its downstream targets pitx2, lefty1 and lefty2. Partial depletion of hspb7 causes concordant heart, brain and visceral laterality defects, indicating that loss of KV cilia motility leads causes coordinated but randomized laterality. Reducing hspb12 leads to similar alterations in the expression of downstream laterality genes, but at a lower penetrance. Simultaneous reduction of hspb7 and hspb12 randomizes heart, brain and visceral laterality, suggesting that these two genes have partially redundant functions in the establishment of left-right asymmetry. In addition, both hspb7 and hspb12 are expressed in the precardiac mesoderm and in the yolk syncytial layer, which supports the migration and fusion of mesodermal cardiac precursors. In embryos in which the reduction of hspb7 or hspb12 was limited to the yolk, migration defects predominated, suggesting that the yolk expression of these genes rather than heart expression is responsible for the migration defects.

    The carbon isotopic composition of natural gases to determine the origin and gaseous hydrocarbon migration of Brazilian sedimentar basins is analysed. The carbon isotopic ratio of methane from natural gases depends on the process of gas formation and stage of organic matter maturation. In the geochemical surface exploration the biogenic gases are differentiated from thermogenic gases, because the last one is isotopically heavier. As the isotopic composition of methane has not changed during migration, the migrated gases from deeper and more mature source rocks are identified by its relative 13 C enrichment. The methane was separated from chromatography and and the isotopic analysis was done with mass spectrometer. (M.C.K.) [pt

    The impact of rice price-support policies, designed to increase farmers' income and reduce rural-urban migration in the Republic of Korea, is examined for the period 1976-1980 using a polytomous logistic model. "Our findings revealed that the elasticity of migration with respect to rice yield per origin farm household is positive and is significantly different from zero. The elasticities of migration with respect to rate of urbanization, particularly urban concentration-agglomeration, and population size of the destination are also positive and are significantly different from zero.... Our findings questioned the wisdom of employing rice price price-support programs as a viable policy for reducing interregional and rural-to-urban migration in Korea." excerpt

    The inorganic elements potentially migrating from cork to a food simulant [a hydroalcoholic solution containing 12 and 20% (v/v) ethanol] have been determined by means of inductively coupled plasma (ICP) with atomic emission and mass spectrometric detection. The experimental instrumental conditions were evaluated in depth, taking into account spectroscopic and nonspectroscopic interference caused by the presence of ethanol and other components in the sample. We report concentrations ranging from 4 μg kg(-1) for Cd to 28000 μg kg(-1) for Al in the food simulant (concentrations given in kilograms of cork). The values found for Ba, Mn, Fe, Cu, and Zn have been compared with the guideline values stated in EU Regulation 10/2011. In all cases, cork met the general safety criteria applicable to food contact material. Finally, we have proposed water as an alternative to the hydroalcoholic solution to simplify quantification of the tested elements using ICP techniques.

    "Microeconomic simulations are performed to determine the impact of liberalized commodity trade on Mexican immigrant supply to the United States. The results suggest that a removal of trade barriers will reduce migration flows, but that the reduction will be fairly modest. Specifically, if both countries move from the levels of protection characteristic of the mid-1960s to completely free trade, the ratio of real U.S.-Mexican wages falls by roughly 18 percent. Using an upper bound for the range of empirical estimates of the wage elasticity of immigrant supply, this implies a maximum reduction in migration flows of 35 percent. A unilateral elimination of trade barriers by the United States reduces Mexican immigrant supply by a maximum of 14 percent." excerpt

    Full Text Available The Anatolian Railway began running between Ankara and Haydarpaşa in Istanbul via İzmit and Eskişehir in early 1893, making transportation from Istanbul to the interior of Anatolia very easy. In late 1892, before the railroad was opened, policymakers prepared official reports on the resettlement of migrants along the rail route from Eskişehir to Ankara; and made regulations accordingly. This studyexamines the route of this migration, which first run to the port of İzmit by sea and then reached Ankara by rail. This article discusses the politics of resettlement and the conditions of migrants settled on the railway route during the twenty-year period between 1890 and 1910, when the Balkan Wars provoked mass migration to Anatolia from the Balkans. It analyzes the locations of the new settlements, the conditions in newly founded villages, and the habitability of the wasteland along the railway route. Daily rations, state aid for housing, types of production, agricultural styles, and the position of artisans will also be considered.

    Full Text Available The convergence between tuberculosis (TB and diabetes mellitus (DM will represent a major public health challenge in the near future. DM increases the risk of developing TB by two to three times and also increases the risk of TB treatment failure, relapse, and death. The global prevalence of DM is predicted to rise significantly in the next two decades, particularly in some of the low- and middle-income countries with the highest TB burden. Migration may add further complexity to the effort to control the impact on TB of the growing DM pandemic. Migration may increase the risk of DM, although the magnitude of this association varies according to country of origin and ethnic group, due to genetic factors and lifestyle differences. Migrants with TB may have an increased prevalence of DM compared to the native population, and the risk of TB among persons with DM may be higher in migrants than in autochthonous populations. Screening for DM among migrants, screening migrants with DM for active and latent TB, and improving access to DM care, could contribute to mitigate the effects of DM on TB.

    In 1999, newly-elected Venezuelan President Hugo Chávez initiated a far-reaching social movement as part of a political project known as the Bolivarian Revolution. Inspired by the democratic ideologies of Simón Bolívar, this movement was committed to reducing intractable inequalities that defined Venezuela's Fourth Republic (1958-1998). Given the ambitious scope of these reforms, Venezuela serves as an instructive example to understand the political context of social inequalities and population health. In this article, we provide a brief overview of the impact of egalitarian policies in Venezuela, stressing: (a) the socialist reforms and social class changes initiated by the Bolivarian Movement; (b) the impact of these reforms and changes on poverty and social determinants of health; (c) the sustainability of economic growth to continue pro-poor policies; and (d) the implications of egalitarian policies for other Latin American countries. The significance and implications of Chávez's achievements are now further underscored given his recent passing, leading one to ask whether political support for Bolivarianism will continue without its revolutionary leader.

    2009-09-01

    From an economic perspective that understood it as a spillover of development, migration is now also the subject of socioeconomic investigation incorporating the problems of assimilation, relative deprivation and isolation. The corollary is an increased emphasis on economic and social understanding of migration and its consequences. This entails studying migration or migrants in terms of factors beyond income. Health outcome is important among these non-income factors but at the same time remains less studied. Although there have been a few influential studies on health issues as linked to migration status, the issue of malnutrition in this context continues to be under-researched. This paper explores, theoretically and empirically, migration status and malnutrition in Mumbai in India. An econometric analysis of Demographic and Health Survey data gives insight into the dynamics of child and maternal undernutrition as mediated by migration status in Mumbai.

    The influence of dispersal limitation on species ranges remains controversial. Considering the dramatic impacts of the last glaciation in Europe, species might not have tracked climate changes through time and, as a consequence, their present-day ranges might be in disequilibrium with current climate. For 1016 European plant species, we assessed the relative importance of current climate and limited postglacial migration in determining species ranges using regression modelling and explanatory variables representing climate, and a novel species-specific hind-casting-based measure of accessibility to postglacial colonization. Climate was important for all species, while postglacial colonization also constrained the ranges of more than 50 per cent of the species. On average, climate explained five times more variation in species ranges than accessibility, but accessibility was the strongest determinant for one-sixth of the species. Accessibility was particularly important for species with limited long-distance dispersal ability, with southern glacial ranges, seed plants compared with ferns, and small-range species in southern Europe. In addition, accessibility explained one-third of the variation in species' disequilibrium with climate as measured by the realized/potential range size ratio computed with niche modelling. In conclusion, we show that although climate is the dominant broad-scale determinant of European plant species ranges, constrained dispersal plays an important supplementary role. PMID:21543356

    Full Text Available In the light of the changing socio-economic realities of the presenttimes, this paper explores the complex dynamics underlying Indian immigrants' decision to continue to stay in the United States or to counter migrate back to India. In a reversal of fortunes, the specific set of conditions that once triggered a massive inflow of economic migrants from India to the US has been causing a counter migration to India. Based on a review of literature and an exploratory study involving focus groups the paper identifiessome of the major migration / counter migration related factors. Then, employing a survey, the relative importance of each of these factors is gauged for individuals associated with different professions. In addition, the study explores as a special case the role of tourism related images about the US being held by immigrants as determinants of their migration related decisions. Tourism images held by the migrants and the tourism opportunities provided by the US act more as hygiene factors than as motivators. In course of theexploration, a number of hypotheses are emerged that are of interest to future researchers. The study has got significant implications for migration / counter migration policy makers, industry practitioners, and the migrants themselves.

    Economically developed countries have recruited large numbers of overseas health workers to fill domestic shortages. Recognition of the negative impact this can have on health care in developing countries led the United Kingdom Department of Health to issue a Code of Practice for National Health Service (NHS) employers in 1999 providing ethical guidance on international recruitment. Case reports suggest this guidance had limited influence in the context of other NHS policy priorities. The temporal association between trends in new professional registrations from doctors qualifying overseas and relevant United Kingdom government policy is reported. Government policy documents were identified by a literature review; further information was obtained, when appropriate, through requests made under the Freedom of Information Act. Data on new professional registration of doctors were obtained from the General Medical Council (GMC). New United Kingdom professional registrations by doctors trained in Africa and south Asia more than doubled from 3105 in 2001 to 7343 in 2003, as NHS Trusts sought to achieve recruitment targets specified in the 2000 NHS Plan; this occurred despite ethical guidance to avoid active recruitment of doctors from resource-poor countries. Registration of such doctors declined subsequently, but in response to other government policy initiatives. A fall in registration of South African-trained doctors from 3206 in 2003 to 4 in 2004 followed a Memorandum of Understanding with South Africa signed in 2003. Registrations from India and Pakistan fell from a peak of 4626 in 2004 to 1169 in 2007 following changes in United Kingdom immigration law in 2005 and 2006. Since 2007, registration of new doctors trained outside the European Economic Area has remained relatively stable, but in 2010 the United Kingdom still registered 722 new doctors trained in Africa and 1207 trained in India and Pakistan. Ethical guidance was ineffective in preventing mass

The ECB's responsibility for the primary objective (price stability often contrasts with the requirement for economic growth stabilization policy from the national governments. There are doubts if the current members of Eurozone constitute an optimum currency area (the Eurozone 12 is recently the combination of rapidly growing and slow-growing - low inflationary countries. The differences between the countries will even expand during the European monetary union enlargement by new EU member countries. Consequently the probability of asymmetric shocks will increase. The main question is the ability of ECB to fulfill the needs of all EMU member countries in terms of optimal monetary policy. In the first part the authors analyze differences between the preferences of the ECB and national authorities (governments. The negative experiences of Ireland, Italy and other EMU members with current status quo help us to understand fear of future member countries from possible impact of common monetary policy on their national economies. The second part of the paper deals with interest rates determination by ECB and compares it with expectations (requirements from EMU member and EMU candidate countries. The main contribution of the article may be seen in central bank's preferences analyses – the preferences are defined as the parameters in Taylor rule (the weights given by ECB and national authorities to the price stability and economic growth stimulation. The hypothesis is defined as following: are the preferences of ECB in line with the preferences of national central banks of EMU candidate countries? The empirical analysis is based on the Taylor rule decomposition. The hypothesis is tested by regression analysis. Time series regression model uses relations

    Full Text Available The article outlines the determinants of the state fiscal policy at the present stage of global transformations. Using the principles of financial science it is determined that regulation of financial flows within the fiscal sphere, namely centralization and redistribution of the GDP, which results in the regulation of the financial capacity of economic agents, is of importance. It is emphasized that the urgent measure for improving the tax model is re-considering the provision of fiscal incentives, which are used to stimulate the accumulation of capital, investment activity, innovation, increase of the competitiveness of national products, expansion of exports, increase of the level of the population employment. The necessity of applying the instruments of fiscal regulation of financial flows, which should take place on the basis of institutional economics emphasizing the analysis of institutional changes, the evolution of institutions and their impact on the behavior of participants of economic relations. At the same time it is determined that the maximum effect of fiscal regulation of financial flows is ensured when application of fiscal instruments is aimed not only at achieving the target values of parameters of financial flows but at overcoming institutional deformations as well. It is determined that the optimal movement of financial flows enables creating favorable conditions for development and maintenance of financial balance in the society and achievement of the necessary level of competitiveness of the national economy.

    Energy is an inevitable necessity for human beings. But the energy source is predicted to be scarce in the coming years as a result of population growth. Therefore people prefer energy sources that are renewable, clean and cost effective. Unfortunately there is not a sole energy source to meet these demands. Determination of the appropriate energy policy problem with interactive criteria and alternatives can be viewed as a multiple criteria decision making (MCDM) problem within the context of the long range and strategic process. The analytic network process (ANO), one of MCDM methods, deals with the dependency and feedback that the problem has. The goal of this paper is to apply the ANP model to evaluate the alternative energy sources for the country. Finally when the results are discussed, it is apparent that the model can produce reasonable and applicable solutions for the case. (author)

    2016-05-01

    Full Text Available Background: Education, as a key indicator of human capital, is considered one of the major determinants of internal migration, with previous studies suggesting that human capital accumulates in urban areas at the expense of rural areas. However, there is fragmentary evidence concerning the educational correlates of internal migration in sub-Saharan Africa. Objective: The study questions whether more precise measures of migration in Health and Demographic Surveillance System (HDSS populations support the hypothesis that migrants are self-selected on human capital and more educated people are more likely to leave rural areas or enter urban areas within a geographical region. Methods: Using unique longitudinal data representing approximately 900,000 people living in eight sub-Saharan African HDSS sites that are members of the INDEPTH Network, the paper uses Event History Analysis techniques to examine the relationship between formal educational attainment and in- and out-migration, over the period 2009 to 2011. Results: Between 7Š and 27Š of these local populations are moving in or out of the HDSS area over this period. Education is positively associated with both in- and out-migration in the Kenyan HDSS areas; however, the education effect has no clear pattern in the HDSS sites in Burkina Faso, Mozambique, and South Africa. Conclusions: Empirical results presented in this paper confirm a strong age profile of migration consistent with human capital expectation, yet the results point to variability in the association of education and the propensity to migrate. In particular, the hypothesis of a shift of human capital from rural to urban areas is not universally valid.

    Full Text Available This article discusses the issue of political-legal, social and human rights challenges imposed by irregular migration to Mexico, a nation that has been converted into an important area of destination and transit to the United States. The criminalization of the phenomenon and, therefore, the securitization of immigration policy, endorsed by the National Security Policy, has led to social and humanitarian conditions that are deplorable for undocumented migrants most of the times. It then examines the situation of Mexico between 2001 and 2014 and the reality of international benchmarks in the field. One of the challenges recognized for Immigration and National Security policies on the social level is the stigmatization suffered by irregular migrants both adults and children. In the political-legal arena to challenge the institutionalization of irregular migration as a threat that affects national security and overcomes the disjunction between the established regulations and their implementation.

    The inter-sectoral migration of agricultural labour is a complex but fundamental process of economic development largely affected by the growth of agricultural productivity and the evolution of the agricultural relative income gap. Theory and some recent anecdotal evidence suggest that as an effect of large fixed and sunk costs of out-farm migration, the productivity gap between the agricultural and non-agricultural sectors should behave non-monotonically or following a U-shaped evolution dur...

    Safety rules continue growing rapidly, as if constraining human behaviour was the unique avenue for reaching ultimate safety. Safety rules are essential for a safe system, but their multiplication can have counterproductive effects. To monitor, in an anaesthesia ward, compliance with a process-oriented safety rule, and understand barriers and facilitators which help and hinder physicians from following guidelines. The rule stipulated that the day before surgery anaesthetists had to record in the patient's file the drugs to be used for the anaesthesia (induction, maintenance, airway control). Compliance was assessed before introduction of the rule, immediately after, at 6 months and at 12 months. All medical staff were blinded to the protocol. 717 patient records were included. The results showed an initial compliance with policy, reaching 86% for some items (never 100%). Reduction began within 6 months and returned almost to initial levels within a year. One individual showed poor compliance throughout the study but even initially compliant doctors experienced a reduction. Compliance was higher for complex surgery but lower for unscheduled surgery and when job pressure was greater. Compliance eroded over time. A major trigger of erosion seemed to be lack of continued compliance by a senior member of staff. Rules and procedures constitute fragile safety barriers, and it may be better to forego introducing a new safety rule if it is not considered as a priority by staff and is therefore vulnerable to sacrifice in case of conflict with competitive demands.

    While migration from low- to high-income countries is typically associated with weight gain, the obesity risks of migration from middle-income countries are less certain. In addition to changes in behaviours and cultural orientation upon migration, analyses of changes in environments are needed to explain post-migration risks for obesity. The present study examines the interaction between obesity-related environmental factors and the pattern of migrant acculturation in a sample of 152 Iranian immigrants in Victoria, Australia. Weight measurements, demographics, physical activity levels and diet habits were also surveyed. The pattern of acculturation (relative integration, assimilation, separation or marginalization) was not related to body mass index, diet, or physical activity behaviours. Three relevant aspects of participants’ perception of the Australian environment (physically active environments, social pressure to be fit, unhealthy food environments) varied considerably by demographic characteristics, but only one (physically active environments) was related to a pattern of acculturation (assimilation). Overall, this research highlighted a number of key relationships between acculturation and obesity-related environments and behaviours for our study sample. Theoretical models on migration, culture and obesity need to include environmental factors. PMID:25648171

    Emigration is defined as a synchronized movement of germ cells between the yolk sack and genital ridges. The miraculous migration of germ cells resembles the remigration of salmon traveling from one habitat to other. This migration of germ cells is indispensible for the development of new generations. It is not, however, clear why germ cells differentiate during migration but not at the place of origin. In order to escape harmful somatic signals which might disturb the proper establishment of germ cells forced germ cell migration may be necessary. Another reason may be to benefit from the opportunities of new habitats. Therefore, emigration may have powerful effects on the population dynamics of the immigrant germ cells. While some of these cells do reach their target, some others die or reach to wrong targets. Only germ cell precursors with genetically, and structurally powerful can reach their target. Likewise, epigenetic reprogramming in both migratory and post-migratory germ cells is essential for the establishment of totipotency. During this journey some germ cells may sacrifice themselves for the goodness of the others. The number and quality of germ cells reaching the genital ridge may vary depending on the problems encountered during migration. If the aim in germ cell specification is to provide an optimal ovarian reserve for the continuity of the generation, then this cascade of events cannot be only accomplished at the same level for every one but also are manifested by several outcomes. This is significant evidence supporting the possibility of unique individual ovarian reserve.

    2017-01-01

    Full Text Available Although there is a vast literature that has investigated the dividend policies of firms from developed countries, relatively little research has been published exploring the dividend policies of firms from emerging countries. The literature regarding establishing the relationship between dividend policy and the attributes of non-financial companies listed on Romanian stock market, to the best of our knowledge, remains inexistent. The aim of this study is to identify the main factors influencing dividend policy for the non-financial companies listed on the Bucharest Stock Exchange for a period of ten years from 2007 to 2016. In order to achieve this aim, panel data were collected from the listed companies’ reports and financial statements. The study reveals that dividend policy is positively related to corporate profitability and liquidity and negatively associated with leverage, size, growth, and the state of the economy.

    Full Text Available Agenda setting is the process by which problems and alternative solutions gain or lose public attention (Birkland T. (2007, p.63; Werner J. and Wegrich K. (2007, p.46.. The main factor that determine an issue that it could become a priority, drawing the attention of decision makers, the public, reaching for it to become part of the agenda are: “Window of Opportunity”, which is a strategy used by less powerful groups, which are benefiting from the fact that powerful groups in certain situations may lose control of the agenda, they manage this circumstances to make their case to the priority. Another factor are the “Focus Event” that emphasizes the fact that unexpected events that shock the public opinion, as were the cases of corruption of officials, case “Snowden” or 11 September in the USA, affecting an issue that directly lead the decision-making agenda. Advocacy coalitions, is a form that use less powerful groups by joining on the basis of certain principles, values, beliefs they have about a particular issue. This alliance of values, resources and coordination of actions helps to advance the issue becoming a priority. “Venue shop” as a factor that aims to reach groups through institutions, be heard, be able to attract the attention of decision makers, also using the media as a very important factor nowadays for sensitizing public opinion on the issue and influence in order to become a priority issue. “Policy network” has come as a need of developing a relationship between government and the private sector, thus forming a power dependency relationship mainly the exchange of resources and thereby influencing the political agenda on particular issues. Therefore in this article I will try to argue that these factors affect in various ways becoming determinant that the issue be the priority on the decision agenda. Also, I can say that after the development of the analysis, I think that the two factors have a greater influence

  5. Determinants of Renewable Energy Innovation: Environmental Policies vs. Market Regulation

    International Nuclear Information System (INIS)

    Vona, Francesco; Nesta, Lionel; Nicolli, Francesco

    2012-02-01

    This paper carries out a comprehensive analysis of renewable energy innovations considering four mechanisms suggested by innovation models: 1. policy-inducement; 2. market structure; 3. demand and social cohesion- mainly proxied by income inequality; 4. characteristics of country knowledge base. For OECD countries and years 1970-2005, we build a unique dataset containing time-varying information on quality-adjusted patent production in renewable energy, the latter being a function of environmental policies, green R and D, entry barriers, knowledge stock, knowledge diversity and income inequality. We develop count data models using the Generalized Method of Moments (GMM) to account for endogeneity of policy support. Our synthetic policy index positively affects innovations especially in countries with deregulated energy markets and low entry barriers. The effect of entry barriers and inequality is negative and of similar magnitude as that of policy. Product market liberalization positively affects green patent generation, especially so when ambitious policies are adopted, when the initial level of public R and D expenditures and when the initial share of distributed energy generation is high. Our results are robust to alternative specifications, to the inclusion of technology-specific effects and to the use of quality-adjusted patents as dependent variables. In the latter case, the estimated effect of lowering entry barriers and of knowledge diversity almost double on citation count relatively to patent count. (authors)

The bibliometric analysis of scientific publications on international migration in cites indexes found that the recent researches on these problems acquire interdisciplinary character. It necessitates the transformation of migration study approaches basing on economic, social, institutional theories and concepts synthesis. The article is devoted to the study of theoretical regulations of existing international migration theories in the context of the evolution of scientists’ views on this phenomenon. The author found that the existing theories of international migration should be divided into three categories (microeconomic, macroeconomic, globalizational that contributes to their understanding in the context of implementation possibilities in migrational public administration practice. It allows to determine the theories which should be used for Ukrainian state migration policy constructing and eliminating or reducing the external migration negative effects.

    1967-04-15

    The migration of solid fission products, in particular caesium and ruthenium, in high temperature oxide fuel can create a severe problem during the application of non-destructive burn-up methods employing gamma spectrometry, since caesium-137 is otherwise the most convenient long-lived burn-up monitor and ruthenium-106 can be used to distinguish between fissions in U-235 and Pu-239. As part of an experimental programme to develop burn-up methods, gamma scanning experiments have been performed on slices of irradiated UO{sub 2} pellets using a lithium-drifted germanium detector. The usefulness of the technique for migration studies has been demonstrated by comparing the fission product distribution curves across the specimen diameters with the microstructure of the specimens after polishing and etching.

    Further analysis of droplet migration in a temperature gradient field indicates that different terms can be used to evaluate the solute diffusion coefficient in liquid (D{sub L}) and that there exists a characteristic curve that can describe the motion of all the droplets for a given composition and temperature gradient. Critical experiments are subsequently conducted in succinonitrile (SCN)-salol and SCN-camphor transparent alloys in order to observe dynamic migration processes of a number of droplets. The derived diffusion coefficients from different terms are the same within experimental error. For SCN-salol alloys, D{sub L} = (0.69 {+-} 0.05) x 10{sup -3} mm{sup 2}/s, and for SCN-camphor alloys, D{sub L} = (0.24 {+-} 0.02) x 10{sup -3} mm{sup 2}/s.

    2015-03-15

    A gas chromatography/mass spectrometric method was developed for the simultaneous determination of eight phthalic acid esters (PAEs) in toys and child care articles that are made of plasticized plastic. The novel method was used to determine the total concentration of the PAEs in addition to the migrated PAEs values into artificial saliva, under conditions that simulate real life situations. The extraction method, which was developed for the first time to determine the total concentration of PAEs, utilized a novel optimization of four parameters involving the solvent, time, temperature and weight of sample. The PAEs were extracted with tetrahydrofuran, as extraction the solvent, and using the ultrasonic water bath shaker for 30min, at room temperature. Another extraction method was developed to determine the migrated PAEs into artificial saliva at pH 6.2 and 37°C, implementing a liquid-liquid extraction with chloroform. Both methods were subjected to validation steps in terms of linearity, precision, accuracy and recovery, which ensured that all obtained results were well within the norms of acceptable limits and specifications. The analytes were separated at the following retention times: 4.99, 5.21, 5.31, 6.63, 7.41, 9.05min for di-"isobutyl" phthalate (DIBP), dibutyl phthalate (DBP), bis(2-methoxyethyl)phthalate (DMEP), benzyl butyl phthalate (BBP), dibutyl phthalate (DEHP) and di-n-octyl phthalate (DnOP), respectively. The chromatographic peaks corresponding to di-"isononyl" phthalate (DINP) and di-"isononyl" phthalate (DIDP), were separated, using the extracted ion chromatogram (EIC) mode within the time ranges of 8.05-12.10min for DINP and 8.50-14.50min for DIDP. The instrument detection limits for DIBP, DBP, DMEP, BBP, DEHP, DnOP, DINP and DIDP were determined at 0.100, 0.100, 0.045, 0.035, 0.015, 0.370, 0.320, 0.260μg/ml, respectively. The calibration curve working ranges were determined at 0.5-25μg/ml for DIBP, DBP, DMEP, BBP and DEHP, 2-100μg/ml for

  13. T he normative concept of labour citizenship as a determinant of the global value of economic migration

    Giovanni DI LIETO

    2015-05-01

    Full Text Available This paper outlines the development of the key studies on conceptions of labour, citizenship, and migration, which combine to lay the theoretical foundations of the contemporary global governance in economic migration. The initial concern of this study is to build upon traditional accounts of labour and citizenship in order to develop a link between industrial citizenship and migrant workers’ mobility. Such approach aims at establishing the normative concept of industrial citizenship as a determinant of the social and economic value of human mobility for the purpose of work. This is intended to further the idea that cross-border labour can be not only a pathway to national citizenship for migrants, but also the avenue to the transnational evolution of citizenship in general. The variety of analytical treatments of the concept of labour, citizenship and migration span from ancient Greek philosophy through to the Scholastics and mercantilists, to the forerunners of the classical political economy, and finally to present labour economics, law and political science. Such an interdisciplinary approach challenges the traditional hypothesis of labour as a basic analytical category in which the worker is increasingly invisible, and where the price of labour is regulated through the market in a manner similar to other factors of production.

    Full Text Available The purpose of this article is to define nature, basis, and the effects of the economic development policy conducted by local governments in Poland. The analyses carried out are designed to define the role of local authorities in the management of economic development in the area. Furthermore, the purpose of this article is to analyse instruments for supporting economic development, which can be potentially used by local governments in Poland. The realization of this objective is possible by using descriptive methods based on a review of literature and the various types of documents and analysis on the policy of both the economic development and activities of local government, which implement this policy. The method of system analysis is also partially used in the article, and some results of surveys conducted among Polish and foreign investors and entrepreneurs in 2011 are presented. The article assumes that in spite of having a number of instruments, both formal and material, for encouraging economic development and business development, most local governments narrowly assess the current state of entrepreneurship and development trends, and perform an insufficient analysis of the potential of their area. Secondly, the formulated goals of economic development are not very innovative, ambitious or concrete. Furthermore, they do not arise directly from the analysis of the micro and macro-environment that affects the position and development of local government. Key words:

  17. Not on the radar: the impact of rural health realities on Canadian public policy and HHR migration from Sub-Saharan Africa.

    Science.gov (United States)

    Kazanjian, Arminée; Apland, Lars E; Labonté, Ronald

    2007-01-01

    The policy environment of Health Human Resource (HHR) demands in rural and remote areas of Canada seems to compel health system planners either to ignore or only pay lip service to memoranda of understanding and other non-binding international agreements on ethical principles of recruitment. Despite common acknowledgement that the migration of health professionals from Sub-Saharan Africa (SSA) and the resultant loss of capacity to deliver health services are devastating for populations in that region, Canadian public policy consideration of the "brain drain" of health human resources from SSA seems cursory, at best. As a result, broadly based domestic HHR policies and international development policy objectives invariably seem to conflict and produce unsatisfactory results that continue to be detrimental to populations of source countries in the developing world, while doing little to alleviate the continued reliance of Canada's rural and remote "'gateways" on foreign-trained health professionals. A key challenge for Canadian public policy, at all levels of government, is to coordinate and find common ground, whereby brain drain issues and specific domestic Canadian HHR needs can be simultaneously and effectively addressed. This research explored the congruity between rural HHR policy principles and international development objectives in the context of federal, provincial, and territorial government relations in Canada.

    The knowledge-practice gap in public health is widely known. The importance of using different types of evidence for the development of effective health promotion has also been emphasized. Nevertheless, in practice, intervention decisions are often based on perceived short-term opportunities...... evidence, evidence on costs, and a lack of joint understanding were specific hindrances. Also users' characteristics and the role media play were identified as factors of influence. Attention for individual and social factors within the policy context might provide the key to enhance more sustainable...

    'Full Text:' Elevated concentrations of radon gas indoors are the result or a complicated combination of factors. This report describes results from a facility designed to test and verify theories of radon migration into underground structures. The buildings resemble miniature basements using conventional construction methods, hut eliminate other confounding factors introduced by the activities of occupants. Sensors accumulate data on soil properties such as temperature, moisture, pressure differentials, and permeability, as well as outdoor meteorological conditions and indoor environment. Results indicate that indoor radon concentrations do not correlate with changes in the adjacent soil gas concentration or the rate that radon enters the structure. When no attempt is made to control the indoor environment, periods of highest indoor concentration occur when the rate of entry is low. Methods to identify the driving mechanisms and implication for mitigation and control will he described. (author)

    Full Text Available The article concerns modern state and development of migration processes in SCO member states. As a main method of research statistical analysis was applied. The article shows that migration streams between SCO member states are rather intensive, and the problem of labor migration becomes more and more urgent. The countries of consuming and supplying of labour force are clearly differentiated in the region. For some countries, labor export is the key sector of economy. At the same time, interstate relations between SCO member states sometimes are rather disputed. The most urgent factors causing the development of migration processes in the region were determined. Among them, thefactor of growing outflows from China isespecially noted. It is noted that migration processes are discussed by SCO member states nowadays in terms of illegal migration and international criminality connected with it. It means that the question of labor migration is a real problem. It is indicated that the creation of a specific joint commission on migration policy affiliated with the Council of Foreign Ministers of SCO member states is the necessary condition of effective interaction in migration questions within the framework of Shanghai Cooperation Organization.

    Full Text Available This inquiry considers some effects of migration on the labour markets and the welfare systems found in the EU-15, and from the perspectives of sustainability of the current welfare state regimes. Our inquiry aims to determine whether and to what extent different approaches in regulation of migration flows between the new and old member states are compatible with related economic and demographic findings. Within this context, our research considers regulations affecting migration flows. Our findings suggest that some effects of migration from the EU8+2 on the labour markets and social protection systems found in the EU-15, both with respect to level and structure, do indeed generate effects on migration, especially considering whether migration is based upon economic or welfare decisions. In addition, our inquiry considers perspectives upon restrictive versus liberal migration policies.

    A β-catenin/T cell factor–dependent transcriptional program is critical during cutaneous wound repair for the regulation of scar size; however, the relative contribution of β-catenin activity and function in specific cell types in the granulation tissue during the healing process is unknown. Here, cell lineage tracing revealed that cells in which β-catenin is transcriptionally active express a gene profile that is characteristic of the myeloid lineage. Mice harboring a macrophage-specific deletion of the gene encoding β-catenin exhibited insufficient skin wound healing due to macrophage-specific defects in migration, adhesion to fibroblasts, and ability to produce TGF-β1. In irradiated mice, only macrophages expressing β-catenin were able to rescue wound-healing deficiency. Evaluation of scar tissue collected from patients with hypertrophic and normal scars revealed a correlation between the number of macrophages within the wound, β-catenin levels, and cellularity. Our data indicate that β-catenin regulates myeloid cell motility and adhesion and that β-catenin–mediated macrophage motility contributes to the number of mesenchymal cells and ultimate scar size following cutaneous injury.

    The residual styrene and other volatile organic compounds (VOCs) present in the polystyrene food packaging are of concern as these compounds have the potential to migrate into the food in contact. This work describes a method for quantitative determination of VOCs, namely styrene, toluene, ethyl benzene, iso-propylbenzene and n-propylbenzene that have migrated from polystyrene food packaging into food stimulant by gas chromatography-flame ionization detection (GC-FID). Headspace solid phase micro extraction (HS-SPME) technique was applied for migration test using water as food stimulant. The effects of extraction variables including sample volume, eluotropic strength, extraction temperature, extraction time, desorption time, sample agitation, and salt addition on the amounts of the extracted analyses were studied to obtain the optimal HS-SPME conditions. The optimized method was applied to test the VOCs migrated from polystyrene bowls and cups at storage temperatures ranging from 24 to 80 degree Celsius for 30 min. Styrene and ethyl benzene were found to migrate from the samples into the food stimulant. The migration of analyze was found to be strongly dependent upon the storage temperature. The HS-SPME is useful as an alternative method to determine the migration of VOCs from food packaging material into food stimulant. (author)

    2011-06-01

    Full Text Available The youths’ labour market, and especially insertion employment has a series of particularities defined by aspects such as: flexibility, efficient employment, interest for career but also informal employment, external mobility, including brain drain, segmentation, employment precariousness, income disadvantages, etc. Therefore, also the labour market policy and particularly managing labour mobility especially through the economic and social effects that might be triggered on the local labour market in the origin country, presents a special importance under the conditions of the economic turnaround stage, by promoting new and sustainable jobs, based on knowledge and competences. In the present paper an analysis is made about the youths’ labour market features, and the outcomes of an empirical analysis about graduates’ migration propensity are presented. Suggestions are made for developing a balanced policy for youths’ labour mobility to the benefit of the country of origin.

    A central aim of environmental chemistry is to develop an understanding of processes at the microscopic level, and to develop speciation models to simulate that behaviour, which may be used with transport codes to predict the fate of pollutants on the field scale. In fact, one objective of this HUPA project is to develop a coupled chemical transport computer code, which includes the effects of humic substances, and then apply it to three field scale test cases: 1. a deep hypothetical repository in a salt formation; 2. a shallow, sandy hypothetical repository; 3. a large pile of uranium mine tailings. This work concerns the third case study (U-tailings), which is based upon a real U-tailings pile at Schlema-Alberoda, near Dresden, Saxony, Germany. Environmental problems are inherently complex, and even apparently simple systems, such as a single metal ion interacting with a 'single' surface may be extremely complex. There have been considerable advances in computing power over the last few decades, unfortunately, in order to make calculations solvable in a reasonable time, the models used to simulate the chemistry of the system must be as simple as possible. The interaction between uranium and humic substances has been studied previously. However, the details of the interaction of uranyl cations with the material of the pile have not been modelled. Therefore, the objective here is to develop a simple model of this interaction, ready to use in the migration case study. Experiments were performed at the Czech Technical University, Prague and the data modelled at the University of Manchester. (orig.)

    2016-01-01

    Energy and climate market policy is inherently multiobjective and multilevel, in that desired choices often conflict and are made at a higher level than influenced actors. Analyzing tradeoff between reducing emissions and keeping fuel prices low, while seeking compromise among producers, traders, and consumers is the crux of the policy problem. This paper aims to address this issue by combining multiobjective optimization problems, which allow the study of tradeoff between choices, with equilibrium problems that model the networks and players over which these policies are chosen, to produce a formulation called a Multiobjective Program with Equilibrium Constraints. We apply this formulation to the United States renewable fuel market to help understand why it has been so difficult in releasing the 2014 mandate for the RFS (Renewable Fuel Standard). The RFS ensures that a minimum volume of renewable fuel is included in transportation fuel sold in the United States. Determining the RFS volume requirements involves anticipating market reaction as well as balancing policy objectives. We provide policy alternatives to aid in setting these volume obligations that are applicable to a wide variety of climate and energy market settings and explain why the RFS is not an optimal policy for reducing emissions. - Highlights: • First time a MOPEC has been used to model energy markets and climate policy. • Method to endogenously determine energy policy along with associated tradeoff. • Computationally efficient algorithm for MOPECs and compare to methods. • Explain why the RFS is not an optimal policy for emission reduction.

    2017-04-01

    There has been considerable recent debate around the alleged impact of discretionary fiscal policies - especially austerity policies - on health and health inequalities. Assuming that most of the impact will have to run via the effect of fiscal policies on socioeconomic determinants of health (SDH), it is of interest to gain a further understanding of the relationship between fiscal policies and SDH. Therefore, the aim of this article is to review the recent evidence on the impact of discretionary fiscal policies on key SDH, i.e. income, poverty, education, and employment, in high income OECD countries. We find that there are no simple answers as to how fiscal policy affects those determinants of health. The effects of contractionary and expansionary fiscal policies on the analyzed SDH vary considerably across countries and will largely depend on the pre-crisis situation. Contractionary fiscal policies seem to have increased poverty, while their impact on income inequality will be influenced by the composition of the implemented measures. More empirical research trying to directly link fiscal policies to health outcomes, while taking into account of some of the mechanisms encountered here, would be worthwhile.

    "We analyze the income-redistribution effects of international migration in the host and source country in a general equilibrium framework. The well-known result that marginal migration leaves the welfare of nonmigrants unaffected is discussed in more detail with regard to shifts in national income distributions. With endogenous goods' prices the consequences for the income distribution are in general ambiguous--we show possibilities for an estimation of their magnitude. As long as wage disparities determine the direction of migration it increases world efficiency. However, redistributive policies may generate migration towards the low-wage country."

    Over recent years Malta has experienced a growing influx of migrants from Africa. With the aim of defining demographic characteristics and assessing the prevalence of conditions of public health significance among asylum seekers in Malta, a clinical research study was implemented in the framework of the European Union project 'Mare nostrum'. From August 2010 to June 2011 a dermatologist and an infectious diseases specialist performed general and specialist health assessment of migrants hosted in open centres. Migrants included in the study were 2216, 82.7% were males, their mean age was 25 years and 70.1% were from Somalia. Out of the total females, 42.5% had undergone some type of Female Genital Mutilation/Cutting. A total of 5077 diagnoses were set, most common were skin diseases (21.9%), respiratory diseases (19.8%) and gastro-enteric diseases (14.2%), whereas 31% of migrants reported good health conditions. Immigrants have a lower morbidity burden compared with their fellow countrymen living in the origin country. However, living conditions during the journey, in transit countries and after arrival can influence their health status. The present study provides a comprehensive picture of this growing population that is in need for health promotion, mental health services and fair policy planning. © The Author 2013.

  2. Determinants of dividend policy: Evidence from listed firms in the African stock exchanges

    2013-01-01

    Full Text Available The study demonstrates that much of the existing theoretical literature on dividend policy can be applied to the emerging capital markets of Africa. Using available financial data of listed firms in the 29 stock exchanges in Africa, the study finds similarities in the determinants of dividend policy in African firms with those in most developed economies. In particular, agency costs are found to be the most dominant determinant of dividend policy among African firms. The finding is non-synonymous with emerging capital markets which have a high concentration of private ownership and trading volumes. Agency cost theory may be important in both emerging and developed capital markets but the nature of the agency problem may be different in each case. Other factors such as level of market capitalization, age and growth of firms, as well as profitability also play key roles in the dividend policy of listed African firms.

    The Nationally Determined Contributions are allowing countries to examine options for reducing emissions through a range of domestic policies. India, like many developing countries, has committed to reducing emissions through specific policies, including building energy codes. Here we assess the potential of these sectoral policies to help in achieving mitigation targets. Collectively, it is critically important to see the potential impact of such policies across developing countries in meeting national and global emission goals. Buildings accounted for around one third of global final energy use in 2010, and building energy consumption is expected to increase as income grows in developing countries. Using the Global Change Assessment Model, this study finds that implementing a range of energy efficiency policies robustly can reduce total Indian building energy use by 22% and lower total Indian carbon dioxide emissions by 9% in 2050 compared to the business-as-usual scenario. Among various policies, energy codes for new buildings can result in the most significant savings. For all building energy policies, well-coordinated, consistent implementation is critical, which requires coordination across different departments and agencies, improving capacity of stakeholders, and developing appropriate institutions to facilitate policy implementation.

  4. Adaptive Policies for Reducing Inequalities in the Social Determinants of Health

    Directory of Open Access Journals (Sweden)

    Gemma Carey

    2015-11-01

    Full Text Available Inequalities in the social determinants of health (SDH, which drive avoidable health disparities between different individuals or groups, is a major concern for a number of international organisations, including the World Health Organization (WHO. Despite this, the pathways to changing inequalities in the SDH remain elusive. The methodologies and concepts within system science are now viewed as important domains of knowledge, ideas and skills for tackling issues of inequality, which are increasingly understood as emergent properties of complex systems. In this paper, we introduce and expand the concept of adaptive policies to reduce inequalities in the distribution of the SDH. The concept of adaptive policy for health equity was developed through reviewing the literature on learning and adaptive policies. Using a series of illustrative examples from education and poverty alleviation, which have their basis in real world policies, we demonstrate how an adaptive policy approach is more suited to the management of the emergent properties of inequalities in the SDH than traditional policy approaches. This is because they are better placed to handle future uncertainties. Our intention is that these examples are illustrative, rather than prescriptive, and serve to create a conversation regarding appropriate adaptive policies for progressing policy action on the SDH.

  5. Determining the privacy policy deficiencies of health ICT applications through semi-formal modelling.

    2011-02-01

    To ensure that patient confidentiality is securely maintained, health ICT applications that contain sensitive personal information demand comprehensive privacy policies. Determining the adequacy of these policies to meet legal conformity together with clinical users and patient expectation is demanding in practice. Organisations and agencies looking to analyse their Privacy and Security policies can benefit from guidance provided by outside entities such as the Privacy Office of their State or Government together with law firms and ICT specialists. The advice given is not uniform and often open to different interpretations. Of greater concern is the possibility of overlooking any important aspects that later result in a data breach. Based on three case studies, this paper considers whether a more formal approach to privacy analysis could be taken that would help identify the full coverage of a Privacy Impact Analysis and determine the deficiencies with an organisation's current policies and approach. A diagrammatic model showing the relationships between Confidentiality, Privacy, Trust, Security and Safety is introduced. First the validity of this model is determined by mapping it against the real-world case studies taken from three healthcare services that depend on ICT. Then, by using software engineering methods, a formal mapping of the relationships is undertaken to identify a full set of policies needed to satisfy the model. How effective this approach may prove as a generic method for deriving a comprehensive set of policies in health ICT applications is finally discussed. Copyright © 2010 Elsevier Ireland Ltd.

    Dendritic cells (DC) are professional Antigen-Presenting Cells scattered throughout antigen-exposed tissues and draining lymph nodes, and survey the body for pathogens. Their ability to migrate through tissues, a 3D environment, is essential for an effective immune response. Upon infection, recognition of Pathogen-Associated Molecular Patterns (PAMP) by Toll-like receptors (TLR) triggers DC maturation. Mature DC (mDC) essentially use the protease-independent, ROCK-dependent amoeboid mode in vivo , or in collagen matrices in vitro . However, the mechanisms of 3D migration used by human immature DC (iDC) are still poorly characterized. Here, we reveal that human monocyte-derived DC are able to use two migration modes in 3D. In porous matrices of fibrillar collagen I, iDC adopted the amoeboid migration mode. In dense matrices of gelled collagen I or Matrigel, iDC used the protease-dependent, ROCK-independent mesenchymal migration mode. Upon TLR4 activation by LPS, mDC-LPS lose the capacity to form podosomes and degrade the matrix along with impaired mesenchymal migration. TLR2 activation by Pam 3 CSK 4 resulted in DC maturation, podosome maintenance, and efficient mesenchymal migration. Under all these conditions, when DC used the mesenchymal mode in dense matrices, they formed 3D podosomes at the tip of cell protrusions. Using PGE 2 , known to disrupt podosomes in DC, we observed that the cells remained in an immature status and the mesenchymal migration mode was abolished. We also observed that, while CCL5 (attractant of iDC) enhanced both amoeboid and mesenchymal migration of iDC, CCL19 and CCL21 (attractants of mDC) only enhanced mDC-LPS amoeboid migration without triggering mesenchymal migration. Finally, we examined the migration of iDC in tumor cell spheroids, a tissue-like 3D environment. We observed that iDC infiltrated spheroids of tumor cells using both migration modes. Altogether, these results demonstrate that human DC adopt the mesenchymal mode to

    The migration of low molecular weight organic compounds through polyethylene terephthalate (PET) films was determined by using a custom permeation cell assembly. Fatty food simulant (Miglyol 812) was added to the receptor chamber, while the donor chamber was filled with 1% and 10% (v/v) migrant compounds spiked in simulant. The permeation cell was maintained at 40°C, 66°C, 100°C or 121°C for up to 25 days of polymer film exposure time. Migrants in Miglyol were directly quantified without a liquid-liquid extraction step by headspace-GC-MS analysis. Experimental diffusion coefficients (DP) of toluene, benzyl alcohol, ethyl butyrate and methyl salicylate through PET film were determined. Results from Limm's diffusion model showed that the predicted DP values for PET were all greater than the experimental values. DP values predicted by Piringer's diffusion model were also greater than those determined experimentally at 66°C, 100°C and 121°C. However, Piringer's model led to the underestimation of benzyl alcohol (Áp = 3.7) and methyl salicylate (Áp = 4.0) diffusion at 40°C with its revised "upper-bound" Áp value of 3.1 at temperatures below the glass transition temperature (Tg) of PET (<70°C). This implies that input parameters of Piringer's model may need to be revised to ensure a margin of safety for consumers. On the other hand, at temperatures greater than the Tg, both models appear too conservative and unrealistic. The highest estimated Áp value from Piringer's model was 2.6 for methyl salicylate, which was much lower than the "upper-bound" Áp value of 6.4 for PET. Therefore, it may be necessary further to refine "upper-bound" Áp values for PET such that Piringer's model does not significantly underestimate or overestimate the migration of organic compounds dependent upon the temperature condition of the food contact material.

In the European Union, an integrated and inclusive approach of the migration issue is necessary. But a common policy on migration rests an ambitious objective. A common approach of the economic migration management and the harmonization of the migration policies of the Member States represented a challenge for the European Union and will become urgent in the future, especially due to the demographic ageing.

    Full Text Available This work analyses the most influential factors over the migratory calendar of Moroccan married people moving to Spain from the gender-related perspective. It uses data coming from an ethnographic survey (=262 individuals applied in 2013 to Moroccan population in Navarre. Logistic regression models are estimated to forecast which variables have more influence on the accelerated family reunification of such individuals. Results show that in both models, male and female, the most relevant determinant is the fact about if women do work in the same year of the reunification, followed by the time interval between the reunification and year 2008. Moreover, in the male model, the opinion of men about female occupation outside the home is very important, while in the female one there are remarkable variables related to social capital such as: spouse’s age, having small children and being the head of householdor not. The conclusion is that early family reunification in Moroccans reveals a reality wich is conditioned both by economic motivations and gender differences.

    Full Text Available Abstract Background Smoking during pregnancy has been associated with socioeconomic determinants and it is recognized as the most important preventable risk factor for an unsuccessful pregnancy outcome. Turkey has national data on the prevalance of smoking during pregnancy; however there is no data on the characteristics of the high-risk population. This is a field study that aims to identify socioeconomic determinants for smoking during pregnancy as well as differentiating the daily and occasional smokers. Method Cross sectional study was conducted among women with 0-5 year old children living in the area served by Primary Health Care Center (PHCC in Burhaniye, Turkey. Face-to-face interviews were conducted by the researchers during January-March 2008 at the home of the participants with 83.7% response rate (n = 256. The relation of "smoking during pregnacy" and "daily smoking during pregnancy" with the independent variables was determined with χ2 tests. Women's age, educational level, number of previous births, place of origin, migration, partner's educational level, poverty, perceived income, social class were evaluated. Statistical significance was achieved when the p value was less than 0.05. The variables in relation with the dependent variables in the χ2 tests were included in the forward-stepwise logistic analysis. Results Prevalance of smoking during pregnancy was 22.7%.

    Monitoring and evaluation (M&E) have gradually become important and regular components of the policy-making process in Mexico since, and even before, the World Health Organization (WHO) Commission on Social Determinants of Health (CSDH) called for interventions and policies aimed at tackling the social determinants of health (SDH). This paper presents two case studies to show how public policies addressing the SDH have been monitored and evaluated in Mexico using reliable, valid, and complete information, which is not regularly available. Prospera, for example, evaluated programs seeking to improve the living conditions of families in extreme poverty in terms of direct effects on health, nutrition, education and income. Monitoring of Prospera's implementation has also helped policy-makers identify windows of opportunity to improve the design and operation of the program. Seguro Popular has monitored the reduction of health inequalities and inequities evaluated the positive effects of providing financial protection to its target population. Useful and sound evidence of the impact of programs such as Progresa and Seguro Popular plus legal mandates, and a regulatory evaluation agency, the National Council for Social Development Policy Evaluation, have been fundamental to institutionalizing M&E in Mexico. The Mexican experience may provide useful lessons for other countries facing the challenge of institutionalizing the M&E of public policy processes to assess the effects of SDH as recommended by the WHO CSDH.

    2009-04-09

    There is a lack of evidence to inform policy development on the reasons why health professionals migrate. Few studies have sought to empirically determine factors influencing the intention to migrate and none have explored the relationship between factors. This paper reports on the first international attempt to investigate the migration intentions of pharmacy students and identify migration factors and their relationships. Responses were gathered from 791 final-year pharmacy students from nine countries: Australia, Bangladesh, Croatia, Egypt, Portugal, Nepal, Singapore, Slovenia and Zimbabwe. Data were analysed by means of Principal Components Analysis (PCA) and two-step cluster analysis to determine the relationships between factors influencing migration and the characteristics of subpopulations most likely and least likely to migrate. Results showed a significant difference in attitudes towards the professional and sociopolitical environment of the home country and perceptions of opportunities abroad between those who have no intention of migrating and those who intend to migrate on a long-term basis. Attitudes of students planning short-term migration were not significantly different from those of students who did not intend to migrate. These attitudes, together with gender, knowledge of other migrant pharmacists and past experiences abroad, are associated with an increased propensity for migration. Given the influence of the country context and environment on migration intentions, research and policy should frame the issue of migration in the context of the wider human resource agenda, thus viewing migration as one form of attrition and a symptom of other root causes. Remuneration is not an independent stand-alone factor influencing migration intentions and cannot be decoupled from professional development factors. Comprehensive human resource policy development that takes into account the issues of both remuneration and professional development are necessary

    An optimization scheme for reservoir development was examined considering the value of the resource, choice of completion and production techniques, and boundary conditions for the reservoir. A 3-phase semi-analytic single-well model was formulated to determine the reservoir response for any completion and production policy. Second, an optimization scheme based on the discrete version of the maximum principle of Pontryagin and the Fibonacci search method was formulated to determine the optimal production and completion policy. Both models are combined in a general algorithm of solution proposed to solve the optimization problem, and a computer code was developed and tested.

    This study focuses on the uses of the electrical tomography and its relationship with hydrochemical data in order to characterize contaminated groundwater flows in fractured aquifers. The studied area is contaminated with different hazardous substances like lyndanes, organochlorinated compounds and benzenes coming from the old non-controlled Sardas landfill. The enormous volumes of wastes filling the landfill have generated a convoluted mixture of leachates. Due to the lack of a landfill liner, the leachates have migrated through the fractured Eocene marls towards the Gallego River. The striking correlation between high concentrations of polluted groundwater and low electrical resistivity of the subsurface (< 8 Ω·m) allows defining the principal contaminant migration route thanks to the distribution of these conductive anomalies. This mapping verifies that there is intense tectonical–structural control of the leachate migration, because the deep migration presents the same direction as the geological axis fold. - Highlights: • The outcrop topographic reconstruction is done using cores and aerial photographs. • Hydrochemical and geophysical data allow defining two leachate migration paths. • Conductive anomalies in ERT are linked to high contaminant concentration. • The distribution of conductive anomalies defines the fractured basement migration. • The plume direction reflects important tectonic control in the migration process.

  18. Migration and AIDS.

    Science.gov (United States)

    1998-01-01

    This article presents the perspectives of UNAIDS and the International Organization for Migration (IOM) on migration and HIV/AIDS. It identifies research and action priorities and policy issues, and describes the current situation in major regions of the world. Migration is a process. Movement is enhanced by air transport, rising international trade, deregulation of trade practices, and opening of borders. Movements are restricted by laws and statutes. Denial to freely circulate and obtain asylum is associated with vulnerability to HIV infections. A UNAIDS policy paper in 1997 and IOM policy guidelines in 1988 affirm that refugees and asylum seekers should not be targeted for special measures due to HIV/AIDS. There is an urgent need to provide primary health services for migrants, voluntary counseling and testing, and more favorable conditions. Research is needed on the role of migration in the spread of HIV, the extent of migration, availability of health services, and options for HIV prevention. Research must be action-oriented and focused on vulnerability to HIV and risk taking behavior. There is substantial mobility in West and Central Africa, economic migration in South Africa, and nonvoluntary migration in Angola. Sex workers in southeast Asia contribute to the spread. The breakup of the USSR led to population shifts. Migrants in Central America and Mexico move north to the US where HIV prevalence is higher.

  19. Radioactive waste: institutional determinants of management and disposal policy in three European countries

    International Nuclear Information System (INIS)

    Berkhout, Frans.

    1989-01-01

    The objective of this thesis has been to write a detailed historical account of the policy and practice of radioactive waste management in Britain, Sweden and West Germany, and to draw out implications for theory and public policy. By comparing the evolution of the policy process in three countries it has been possible to develop a better understanding of the particular operational, regulatory and political factors determining policy in each case. The main conclusions are three-fold. First, the presence or absence of commitments to the reprocessing of spent fuel for a wide range of strategic, industrial and legal reasons have been critical to the success in finding an acceptable radwaste management and disposal policy (or strategy). Politically it is not possible to make a clear distinction between radwaste management and policy for the rest of the back-end of the nuclear fuel cycle. Second, because of this complex but intimate relationship to reprocessing policy, the dynamism and consistency of radwaste policies are highly dependent on the industrial and political contexts of the drive to reprocessing. Traditionally a view on reprocessing has been virtually synonymous with a faith or scepticism in the future of nuclear power. Third, the policy process, and indeed its goals was rather unique to national circumstances (the legal and institutional framework, industrial and political structures). This demonstrates one of the principle arguments of the thesis which is that the innovation process for radwaste management and disposal technologies cannot be seen merely as a technical process, but has to be seen as a process of political and institutional negotiations.

    Dramatic increases in the migration of human resources for health (HRH) from developing countries like the Philippines can have consequences on the sustainability of health systems. In this paper, we trace the outflows of HRH from the Philippines, map out its key causes and consequences, and identify relevant policy responses. This mixed method study employed a decentered, comparative approach that involved three phases: (a) a scoping review on health workers' migration of relevant policy documents and academic literature on health workers' migration from the Philippines; and primary data collection with (b) 37 key stakeholders and (c) household surveys with seven doctors, 329 nurses, 66 midwives, and 18 physical therapists. Filipino health worker migration is best understood within the context of macro-, meso-, and micro-level factors that are situated within the political, economic, and historical/colonial legacy of the country. Underfunding of the health system and un- or underemployment were push factors for migration, as were concerns for security in the Philippines, the ability to practice to full scope or to have opportunities for career advancement. The migration of health workers has both negative and positive consequences for the Philippine health system and its health workers. Stakeholders focused on issues such as on brain drain, gain, and circulation, and on opportunities for knowledge and technology transfer. Concomitantly, migration has resulted in the loss of investment in human capital. The gap in the supply of health workers has affected the quality of care delivered, especially in rural areas. The opening of overseas opportunities has commercialized health education, compromised its quality, and stripped the country of skilled learning facilitators. The social cost of migration has affected émigrés and their families. At the household level, migration has engendered increased consumerism and materialism and fostered dependency on overseas

    Full Text Available Within the EU, there is no common policy on migration; there are common policies on certain aspects of migration. The Member States fear of migration, but their economies and societies will further need migrant workers. Labour force migration have positive, but also negative consequences for all parties involved: receiving countries, origin countries and migrant workers. Within this framework, a common approach of the migration management and the harmonization of the economic migration policies of the Member States represent already one of the most important challenges for the European Union and will be further emphasized.

    2009-03-01

    Different silicone baking moulds (37 samples) were characterized with respect to potential migrating substances using 1H-NMR, RP-HPLC-UV/ELSD and GC techniques. In all cases cyclic organosiloxane oligomers with the formula [Si(CH3)2-O]n were identified (n = 6 ... 50). Additionally, linear, partly hydroxyl-terminated organosiloxanes HO-[Si(CH3)2-O]n-H (n = 7 ... 20) were found in 13 samples. No substances other than siloxanes could be detected, meaning the migrants mainly consist of organopolysiloxanes. Based on this knowledge, a 1H-NMR quantification method for siloxanes was established for the analysis of both simulants and foodstuffs. Validation of the 1H-NMR method gave suitable performance characteristics: limit of detection 8.7 mg kg(-1) oil, coefficient of variation 7.8% (at a level of 1.0 mg kg(-1) food). Migration studies were carried out with simulants (olive oil, isooctane, ethanol (95%), Tenax) as well as preparation of different cakes. From the 1st to 10th experiment, siloxane migration into cakes only slightly decreased, with a significant dependence on fat content. Migration never exceeded a level of 21 mg kg(-1) (3 mg dm(-2)) and was, therefore, well below the overall migration limit of 60 mg kg(-1) (10 mg dm(-2)). However, migration behaviour into simulants differed completely from these results.

The conventional method uses differential calculus on thesystem cost function to determine the economic lot size and optimal number of shipmentsfor such an integrated vendor-buyer system, whereas the proposed two-phase algebraicapproach is a straightforward method that enables practitioners who may not havesufficient knowledge of calculus to manage real-world systems more effectively.

    Full Text Available This paper analyzes the phenomenon of “forced migration” in Malaysia. It examines the nature of forced migration, the challenges faced by Malaysia, the policy responses and their impact on the country and upon the forced migrants. It considers forced migration as an event hosting multifaceted issues related and relevant to forced migrants and suggests that Malaysia has been preoccupied with the issue of forced migration movements. This is largely seen in various responses invoked from Malaysia due to “south-south forced migration movements.” These responses are, however, inadequate in terms of commitment to the international refugee regime. While Malaysia did respond to economic and migration challenges, the paper asserts that such efforts are futile if she ignores issues critical to forced migrants.

  9. The role of family decision in internal migration: the case of India.

    Bhattacharyya, B

    1985-01-01

    This paper analyzes the effects of family decisions and individual decisions on rural-urban migration in India under 2 different rural institutions--family farm and wage labor systems. An analytical framework for explaining family migration decisions reveals that whenever a member of the extended family migrates, he gives up his share in the produce of the family farm. When this happens, the number of adult members on the farm goes down and the total product is affected. 3 case studies of Indian villages are analyzed for this study. 2 empirical relations are examined: 1) if individual migration decisions are predominant, and 2) if family decisions are important in determining the overall flow of migration. Relationships between migration decisions and other variables, such as: 1) number of males in urban areas; 2) urban wages; 3) daily wage rate; 4) average agricultural income; 5) railway distance between rural and urban areas; 6) size of the labor market in destination region; 7) probability that a migrant arriving in an urban area will find a job; and 8) comsumption expenditure, in urban areas estimated by working class consumer price index, are determined. Results show that: 1) the market determined wage variable does not play a very significant role in migration decisions; 2) distance is one of the most important variables in analyzing migration; and 3) the aggregate flow of migration is affected if migration decisions are predominantly family decisions. These findings have relevant policy implications for less developed countries (LDCs), especially because large flows of rural-urban migration in recent years have forced governments to adopt policies for controlling the flows to reduce the burden of unemployment in the urban areas. Government policies affecting rural institutions will have an impact on migration flow; those that lead to a reduction of uncertainty in agriculture will affect average per-capita consumption levels in family farms and hence

  10. THE UNILATERAL DETERMINATION OF PRICE – A QUESTION OF CERTAINTY OR PUBLIC POLICY?

    Directory of Open Access Journals (Sweden)

    Hanri M du Plessis

    2013-08-01

    Full Text Available The unilateral determination of price has been a controversial issue for an extended period of time. During the 1990s the Supreme Court of Appeal asked if the rule should still form part of South African law. Specifically, the court raised a few questions in respect of the rule and commented that the rule as applied in South African law is illogical. The court also remarked that public policy, bona fides and contractual equity might also be employed when considering such issues. Despite the criticisms of the Supreme Court of Appeal, it would seem that the rule still forms part of our law. This article investigates whether or not the rule should be retained in the South African common law. The answer will depend on two separate questions: Is the rule a manifestation of the requirement of certainty of price? If not, does public policy require that the rule be retained? The article shows that the rule prohibiting the unilateral determination of price should not be seen as a manifestation of the requirement of certainty of price. This is because there are various circumstances where the unilateral determination of the price results in certainty of price or can be applied in such a way as to arrive at certainty of price. Most of these arguments require that the discretion to determine the price should not be unfettered and should be subject to some objective standard. This can be done expressly or tacitly in the contract, or an objective standard (in the form of reasonableness will be implied by law. Thereafter, the article considers various public policy considerations that could be used to determine if a discretion to determine the price should be enforced. The article argues that public policy may dictate that such a discretion should be valid and enforceable provided that it is not unfettered and subject to an external objective standard or reasonableness. However, in cases where an unfair bargaining position is present, public policy may dictate

  11. Determining Optimal Replacement Policy with an Availability Constraint via Genetic Algorithms

    Full Text Available We develop a model and a genetic algorithm for determining an optimal replacement policy for power equipment subject to Poisson shocks. If the time interval of two consecutive shocks is less than a threshold value, the failed equipment can be repaired. We assume that the operating time after repair is stochastically nonincreasing and the repair time is exponentially distributed with a geometric increasing mean. Our objective is to minimize the expected average cost under an availability requirement. Based on this average cost function, we propose the genetic algorithm to locate the optimal replacement policy N to minimize the average cost rate. The results show that the GA is effective and efficient in finding the optimal solutions. The availability of equipment has significance effect on the optimal replacement policy. Many practical systems fit the model developed in this paper.

  12. Landowner behavior can determine the success of conservation strategies for ecosystem migration under sea-level rise.

    The human aspects of conservation are often overlooked but will be critical for identifying strategies for biological conservation in the face of climate change. We surveyed the behavioral intentions of coastal landowners with respect to various conservation strategies aimed at facilitating ecosystem migration for tidal marshes. We found that several popular strategies, including conservation easements and increasing awareness of ecosystem services, may not interest enough landowners to allow marsh migration at the spatial scales needed to mitigate losses from sea-level rise. We identified less common conservation strategies that have more support but that are unproven in practice and may be more expensive. Our results show that failure to incorporate human dimensions into ecosystem modeling and conservation planning could lead to the use of ineffective strategies and an overly optimistic view of the potential for ecosystem migration into human dominated areas.

  13. Determination of Swimming Speeds and Energetic Demands of Upriver Migrating Fall Chinook Salmon (Oncorhynchus Tshawytscha) in the Klickitat River, Washington.

    2002-08-30

    This report describes a study conducted by Pacific Northwest National Laboratory for the Bonneville Power Administration's Columbia Basin Fish and Wildlife Program during the fall of 2001. The objective was to study the migration and energy use of adult fall chinook salmon (Oncorhynchus tshawytscha) traveling up the Klickitat River to spawn. The salmon were tagged with either surgically implanted electromyogram (EMG) transmitters or gastrically implanted coded transmitters and were monitored with mobile and stationary receivers. Swim speed and aerobic and anaerobic energy use were determined for the fish as they attempted passage of three waterfalls on the lower Klickitat River and as they traversed free-flowing stretches between, below, and above the falls. Of the 35 EMG-tagged fish released near the mouth of the Klickitat River, 40% passed the first falls, 24% passed the second falls, and 20% made it to Lyle Falls. None of the EMG-tagged fish were able to pass Lyle Falls, either over the falls or via a fishway at Lyle Falls. Mean swimming speeds ranged from as low as 52.6 centimeters per second (cm s{sup -1}) between falls to as high as 189 (cm s{sup -1}) at falls passage. Fish swam above critical swimming speeds while passing the falls more often than while swimming between the falls (58.9% versus 1.7% of the transmitter signals). However, fish expended more energy swimming the stretches between the falls than during actual falls passage (100.7 to 128.2 kilocalories [kcals] to traverse areas between or below falls versus 0.3 to 1.0 kcals to pass falls). Relationships between sex, length, and time of day on the success of falls passage were also examined. Average swimming speeds were highest during the day in all areas except at some waterfalls. There was no apparent relationship between either fish condition or length and successful passage of waterfalls in the lower Klickitat River. Female fall chinook salmon, however, had a much lower likelihood of

    A systematic differentiation of culture- in contrast to migration-related influence factors in diagnostic and therapeutic processes is introduced. "Culture-related" refers to characteristics caused by values, behavior norms and religious attitudes of the ethnic community a person belongs to. "Migration-specific" refers to consequences of moving one's residence from one country to another (e. g., absence of family, trouble with authorities concerning the legal status or ambivalence with respect to returning to the home country). Based on a theoretic background of these determinants, categories for a content analysis were defined and applied to the treatment records of n = 55 first generation immigrants treated in a psychiatric day clinic of an university hospital. The results suggest that migration biography should not only be considered as affecting vulnerability in the genesis of a mental illness, but rather be classified as a factor of at least as much relevance for therapeutic situations as the usually named cultural diversity: summarizing the results of the qualitative content analysis of the entire treatment courses more cases were influenced by migration specific aspects rather than culture specific aspects.

    We develop a model and a genetic algorithm for determining an optimal replacement policy for power equipment subject to Poisson shocks. If the time interval of two consecutive shocks is less than a threshold value, the failed equipment can be repaired. We assume that the operating time after repair is stochastically nonincreasing and the repair time is exponentially distributed with a geometric increasing mean. Our objective is to minimize the expected average cost under an availability requi...

  17. The validation of a method for determining the migration of trace elements from food packaging materials into food

    1997-01-01

    A new radiotracer method has been developed to measure the migration of trace elements from food contact packaging into four standard food simulants; acetic acid, ethanol, olive oil, deionised water. A sample of material is irradiated in a thermal neutron flux of 10 16 n x m -2 x s -1 to activate the trace elements and produce a range of radionuclides. The samples is then placed in the food simulant and the migration of the radionuclides is monitored by performing γ-ray spectrometry on a sample of the simulant. Any radionuclides measured must be due entirely to the migration of the elements present in the plastic, since the simulant itself is not radioactive. Preliminary studies have shown that detection limits of around 0.2 μg x dm -2 (0.002 mg/kg) can be achieved for antimony in a sample of polyethylene terephthalate. This method can now been extended to measure migration into real foods. This will highlight any differences between the standard simulants currently used and real foods. Since the method only involves irradiation of the packaging material any food matrix can be studied. (author)

  19. Migration: the trends converge.

    Science.gov (United States)

    1985-09-01

    Formerly, Australia, New Zealand, Canada, and the US have served as permanent destinations for immigrants, while Europe's migrants have moved to more northerly countries to work for a time and then returned home. From 1973-1975 Europe's recruitment of foreign workers virtually ended, although family reunion for those immigrants allowed in was encouraged. Problems resulting from this new settlement migration include low paying jobs for immigrant women, high unemployment, and inadequate education for immigrant children. Illegal migrants from Latin America and the Caribbean enter the US and Canada each year while illegal North African immigrants enter Italy, Spain, and Greece. North America, Australia, and Europe have all received political refugees from Asia and Latin America. Increasingly, these foreigners compete in the labor market rather than simply fill jobs the native workers do not want. All the receiving countries have similar policy priorities: 1) more effective ways for controlling and monitoring inflows and checking illegal immigration; 2) encouraging normal living patterns and accepting refugees; and 3) integrating permanent migrants into the host country. Europe's public immigration encouragement prior to the first oil shock, has left some countries with a labor force that is reluctant to return home. It is unlikely that Europe will welcome foreign labor again in this decade, since unemployment among young people and women is high and family reunion programs may still bring in many immigrants. Less immigration pattern change will probably occur in North America, Australia, and New Zealand since these countries' populations are still growing and wages are more flexible. Immigration, regulated by policy, and emigration, determined by market forces, now are working in the same direction and will likely reduce future migration flows.

    Turkey is one of the most energy import dependent countries in the world, suffering deeply from the economic and strategic burdens of oil importation. Our purpose is to determine the factors behind the crude oil import policy of Turkey and to measure their contribution to a well-organized import strategy. We implemented a principle component analysis to construct an Oil Import Vulnerability Index (OIVI) based on four factors, which are crude oil import dependency of primary energy consumption, crude oil import bill as a share of Gross Domestic Product (GDP), non-diversification of import sources, and share of oil in total energy import. The contribution of these factors to the OIVI is found to be approximately equal. While an overall deterioration in the OIVI has been observed during periods of increasing oil prices, better diversification of oil import sources has lead to significant improvements. We suggest Turkish policy-makers implement sound policies, emphasizing diversification of crude oil import sources and reduction of the share of crude oil in primary energy imports to increase energy supply security. This study has also demonstrated that it is possible to construct an index representing crude oil vulnerability caused by import dependency. - Research highlights: {yields}We examine the factors lying behind the crude oil import policy of Turkey. {yields} We measure the contribution of each factor to a well-organized import strategy. {yields} We constrtuct an Oil Import Vulnerability Index using principle component analysis. {yields} We suggest that four factors affect oil import policies with almost equal weights. {yields} Source diversification is found to be the core issue in oil import policies.

    The benefits of prescribing cardiac rehabilitation (CR) for patients following heart surgery is well documented; however, physicians continue to underuse CR programs, and disparities in the referral of women are common. Previous research into the causes of these problems has relied on self-report methods, which presume that physicians have insight into their referral behavior and can describe it accurately. In contrast, the research presented here used clinical judgment analysis (CJA) to discover the tacit judgment and referral policies of individual physicians. The specific aims were to determine 1) what these policies were, 2) the degree of self-insight that individual physicians had into their own policies, 3) the amount of agreement among physicians, and 4) the extent to which judgments were related to attitudes toward CR. Thirty-six Canadian physicians made judgments and decisions regarding 32 hypothetical cardiac patients, each described on 5 characteristics (gender, age, type of cardiovascular procedure, presence/absence of musculoskeletal pain, and degree of motivation) and then completed the 19 items of the Attitude towards Cardiac Rehabilitation Referral scale. Consistent with previous studies, there was wide variation among physicians in their tacit and stated judgment policies, and self-insight was modest. On the whole, physicians showed evidence of systematic gender bias as they judged women as less likely than men to benefit from CR. Insight data suggest that 1 in 3 physicians were unaware of their own bias. There was greater agreement among physicians in how they described their judgments (stated policies) than in how they actually made them (tacit policies). Correlations between attitude statements and CJA measures were modest. These findings offer some explanation for the slow progress of efforts to improve CR referrals and for gender disparities in referral rates.

    Background The benefits of prescribing cardiac rehabilitation (CR) for patients following heart surgery is well documented. However physicians continue to underutilize CR programs and disparities in the referral of women are common. Previous research into the causes of these problems has relied on self-report methods which presume that physicians have insight into their referral behavior and can describe it accurately. In contrast, the research presented here employed clinical judgment analysis (CJA) to discover the tacit judgment and referral policies of individual physicians. Purpose The specific aims were to determine 1) what these policies were, 2) the degree of self-insight that individual physicians had into their own policies, 3) the amount of agreement among physicians, and 4) the extent to which judgments were related to attitudes toward CR. Method Thirty-six Canadian physicians made judgments and decisions regarding 32 hypothetical cardiac patients, each described on five characteristics (gender, age, type of surgical procedure, presence/absence of musculoskeletal pain, and degree of motivation) and then completed the 19 items of the Attitude towards Cardiac Rehabilitation Referral instrument. Results There was wide variation among physicians in their tacit and stated judgment policies. Physicians exhibited greater agreement in what they believed they were doing (stated policies) than in what they actually did (tacit policies). Nearly one-third of the physicians showed evidence of systematic, and perhaps subliminal, gender bias as they judged women as less likely than men to benefit from CR. Correlations between attitude statements and CJA measures were modest. Conclusions These findings offer some explanation for the slow progress of efforts to improve CR referrals and for gender disparities in referral rates. PMID:23784848

    Habitat use has been shown to be an important factor in the bioaccumulation of contaminants in striped bass. This study examines migration in striped bass as part of a larger study investigating bioaccumulation and maternal transfer of xenobiotics to progeny in the San Francisco Estuary system. Habitat use, residence time and spawning migration over the life of females (n = 23) was studied. Female striped bass were collected between Knights Landing and Colusa on the Sacramento River during the spawning runs of 1999 and 2001. Otoliths were removed, processed and aged via otolith microstructure. Subsequently, otoliths were analyzed for strontium/calcium (Sr/Ca) ratio using an electron-microprobe to measure salinity exposure and to distinguish freshwater, estuary, and marine habitat use. Salinity exposure during the last year before capture was examined more closely for comparison of habitat use by the maternal parent to contaminant burden transferred to progeny. Results were selectively confirmed by ion microprobe analyses for habitat use. The Sr/Ca data demonstrate a wide range of migratory patterns. Age of initial ocean entry differs among individuals before returning to freshwater, presumably to spawn. Some fish reside in freshwater year-round, while others return to more saline habitats and make periodic migrations to freshwater. Frequency of habitat shifts and residence times differs among fish, as well as over the lifetime of individual fish. While at least one fish spent its final year in freshwater, the majority of spawning fish spent their final year in elevated salinity. However, not all fish migrated to freshwater to spawn in the previous year. Results from this investigation concerning migration history in striped bass can be combined with contaminant and histological developmental analyses to better understand the bioaccumulation of contaminants and the subsequent effects they and habitat use have on fish populations in the San Francisco Estuary system.

    This research sets out to explore the possibilities for further saving in household electricity consumption through a study of the residents' willingness and behavioural characteristics in electricity saving, as applied within a Chinese context. Based on an extensive literature review, the authors argue that economic benefits, policy and social norms, and past experience may have a positive correlation with household electricity-saving behaviour, while the discomfort caused by electricity-saving activities, may exert a negative effect on it. Through a sample of 816 randomly selected residents in Beijing, the propositions are examined using logit regression analysis. The conclusions support the ideas, concerning both the positive influence of economic benefits, policy and social norms, and past experience as they affect broader electricity-saving behaviour, and the negative influence of the discomfort caused by electricity-saving activities. Finally, some inferences are drawn, and suggestions are offered for policy makers and further studies. - Highlights: → We develop a logistic regression to investigate household electricity saving behaviour. → Determinants for household electricity saving are verified with a questionnaire survey. → Environmental awareness does not impact on household electricity saving directly. → It is prerequisite to focus on both financial subsidy and technology improvement. → Tiered price reform is considered an effective policy for electricity saving.

    The development and implementation of multisectoral policy to improve health and reduce health inequities has been slow and uneven. Evidence is largely focused on the facts of health inequities rather than understanding the political and policy processes. This 5-year funded programme of research investigates how these processes could function more effectively to improve equitable population health. The programme of work is organised in four work packages using four themes (macroeconomics and infrastructure, land use and urban environments, health systems and racism) related to the structural drivers shaping the distribution of power, money and resources and daily living conditions. Policy case studies will use publicly available documents (policy documents, published evaluations, media coverage) and interviews with informants (policy-makers, former politicians, civil society, private sector) (~25 per case). NVIVO software will be used to analyse the documents to see how 'social and health equity' is included and conceptualised. The interview data will include qualitative descriptive and theory-driven critical discourse analysis. Our quantitative methodological work assessing the impact of public policy on health equity is experimental that is in its infancy but promises to provide the type of evidence demanded by policy-makers. Our programme is recognising the inherently political nature of the uptake, formulation and implementation of policy. The early stages of our work indicate its feasibility. Our work is aided by a Critical Policy Reference Group. Multiple ethics approvals have been obtained with the foundation approval from the Social and Behavioural Ethics Committee, Flinders University (Project No: 6786).The theoretical, methodological and policy engagement processes established will provide improved evidence for policy-makers who wish to reduce health inequities and inform a new generation of policy savvy knowledge on social determinants. © Article author

    2008-01-01

    This paper investigates the relevance of external determinants for the adoption of stationary fuel cells (FCs) by different user groups with respect to the marketability of this innovative technology. FCs allow electricity and heat to be decentrally generated in an energy-efficient and potentially environmentally friendly manner. European energy policy is undertaking efforts to increase the proportion of combined heat and power (CHP) plants. A series of studies have spoken of their considerable market potential. A qualitative study was conducted with six focus groups consisting of 49 commercial users and six focus groups with 54 private consumers. The results of the study show that the specific infrastructure required for decentralisation and policy issues are highly relevant for the user adoption of FCs. Security of supply when energy generation is more strongly decentralised, reliable maintenance of the system, and clear political objectives are examples of factors that are considered essential prerequisites for the adoption of this technology

    Full Text Available We consider the problem of determining realistic and easy-to-schedule lot sizes in a multiproduct, multistage manufacturing environment. We concentrate on a specific type of production, namely, flow shop type production. The model developed consists of two parts, lot sizing problem and scheduling problem. In lot sizing problem, we employ binary integer programming and determine reorder intervals for each product using power-of-two policy. In the second part, using the results obtained of the lot sizing problem, we employ mixed integer programming to determine schedules for a multiproduct, multistage case with multiple machines in each stage. Finally, we provide a numerical example and compare the results with similar methods found in practice.

    Victorian local governments are required to develop Municipal Public Health and Wellbeing Plans that incorporate state-level health planning priorities and address the social determinants of health. This paper describes a novel method for evaluating councils' performance against these requirements. Deductive content analysis was used to categorise all actions in 14 local government MPHWPs against Victorian state priorities as well as against social determinants of health policy areas. More than 1,000 actions were identified. However, fewer than half directly addressed a state priority, with many actions addressing policy areas known to be broader determinants of health. In particular, there was a marked focus on leisure and culture, and on building social cohesion through changes to living and working conditions. Councils are working beyond state priorities and there was a clear emphasis on addressing the diverse upstream 'causes of the causes' of health, rather than health promotion behaviour change programs. The approach for data analysis and presentation provides a useful method for rapid appraisal of health and wellbeing actions relative to councils', and the State's, responsibility and efficacy in public health. © 2015 Public Health Association of Australia.

  15. Albania: Trends and patterns, proximate determinants and policies of fertility change

    Directory of Open Access Journals (Sweden)

    Letizia Mencarini

    2008-07-01

    Full Text Available For a very long time, Albania has had one of the highest levels of fertility in Europe: in 2002 the total fertility rate of 2.2 children per woman was the highest in Europe. Although this current level is high, the country has experienced a rapid fertility reduction during the last 50 years: a TFR decline from 7 to 2.2. This reduction has occurred in the absence of modern contraception and abortion, which indicates the significance of investments in the social agenda during the communist regime that produced policies with indirect effects on fertility. Most significant of these were policies focused on education, in particular on female education. Social and demographic settings for a further fertility reduction in Albania have been present since 1990. Contraception and abortion have been legalized and available since the early 1990s, but knowledge of their use is still not widespread in the country, largely due to the interplay between traditional and modern norms of Albanian society. This chapter points out that future fertility levels will be determined not only by new policies that might be introduced, but predominantly by the balance of this interplay.

    To identify the determinants of adequate antenatal care (ANC) utilisation and institutional deliveries among socio-economically disadvantaged migrants living in Delhi, India. In a cross-sectional survey, 809 rural-urban migrant mothers with a child aged below 2 years were interviewed with a pretested questionnaire. Data on receiving antenatal, delivery and post-natal services, migration history and other social, demographic and income were collected. Recent migrants used the services significantly less than settled migrants. ANC was adequate only among 37% (35% of recent migrant women and 39% of settled migrants). Multinomial regression revealed that being a recent migrant, multiparous, illiterate and married to an unskilled worker were significant risk factors for receiving inadequate ANC. Around 53% of deliveries took place at home. ANC seeking has a strong influence on place of delivery: 70% of births to women who received inadequate ANC were at home. Women who are educated, had their first delivery after the age of 20 years and received adequate ANC were more likely to deliver their child in hospital. Post-natal care is grossly neglected among these groups. Migrant women, particularly recent migrants, are at the risk of not receiving adequate maternal healthcare. Because migration is a continuing phenomenon, measures to mitigate disadvantage due to migration need to be taken in the healthcare system. © 2013 John Wiley & Sons Ltd.

    Full Text Available Abstract Introduction Preventative strategies that focus on addressing the social determinants of health to improve healthy eating and physical activity have become an important strategy in British Columbia and Ontario for combating chronic diseases. What has not yet been examined is the extent to which healthy living initiatives implemented under these new policy frameworks successfully engage with and change the social determinants of health. Methods Initiatives active between January 1, 2006 and September 1, 2011 were found using provincial policy documents, web searches, health organization and government websites, and databases of initiatives that attempted to influence to nutrition and physical activity in order to prevent chronic diseases or improve overall health. Initiatives were reviewed, analyzed and grouped using the descriptive codes: lifestyle-based, environment-based or structure-based. Initiatives were also classified according to the mechanism by which they were administered: as direct programs (e.g. directly delivered, blueprints (or frameworks to tailor developed programs, and building blocks (resources to develop programs. Results 60 initiatives were identified in Ontario and 61 were identified in British Columbia. In British Columbia, 11.5% of initiatives were structure-based. In Ontario, of 60 provincial initiatives identified, 15% were structure-based. Ontario had a higher proportion of direct interventions than British Columbia for all intervention types. However, in both provinces, as the intervention became more upstream and attempted to target the social determinants of health more directly, the level of direct support for the intervention lessened. Conclusions The paucity of initiatives in British Columbia and Ontario that address healthy eating and active living through action on the social determinants of health is problematic. In the context of Canada's increasingly neoliberal political and economic policy, the

    Background Migration is difficult to measure because it is highly repeatable. Health and Demographic Surveillance Systems (HDSSs) provide a unique opportunity to study migration as multiple episodes of migration are captured over time. A conceptual framework is needed to show the public health implications of migration. Objective/design Research conducted in seven HDSS centres [International Network for the Demographic Evaluation of Populations and Their Health (INDEPTH) Network], published in a peer-reviewed volume in 2009, is summarised focussing on the age–sex profile of migrants, the relation between migration and livelihoods, and the impact of migration on health. This illustrates the conceptual structure of the implications of migration. The next phase is described, the Multi-centre Analysis of the Dynamics In Migration And Health (MADIMAH) project, consisting of workshops focussed on preparing data and conducting the analyses for comparative studies amongst HDSS centres in Africa and Asia. The focus here is on the (standardisation of) determinants of migration and the impact of migration on adult mortality. Results The findings in the volume showed a relatively regular age structure for migration among all HDSS centres. Furthermore, migration generally contributes to improved living conditions at the place of origin. However, there are potential negative consequences of migration on health. It was concluded that there is a need to compare results from multiple centres using uniform covariate definitions as well as longitudinal analysis techniques. This was the starting point for the on-going MADIMAH initiative, which has increased capacity at the participating HDSS centres to produce the required datasets and conduct the analyses. Conclusions HDSS centres brought together within INDEPTH Network have already provided strong evidence of the potential negative consequences of migration on health, which contrast with the beneficial impacts of migration on

    Full Text Available For full activation of naïve adaptive lymphocytes in skin-draining lymph nodes (LNs, presentation of peptide:MHC complexes by LN-resident and skin-derived dendritic cells (DCs that encountered antigens (Ags is an absolute prerequisite. To get to the nearest draining LN upon intradermal immunization, DCs need to migrate from the infection site to the afferent lymphatics, which can only be reached by traversing a collagen-dense network located in the dermis of the skin through the activity of proteolytic enzymes. Here, we show that mice with altered collagen fibrillogenesis resulting in thicker collagen fibers in the skin display a reduced DC migration to the draining LN upon immune challenge. Consequently, the initiation of the cellular and humoral immune response was diminished. Ag-specific CD8+ and CD4+ T cells as well as Ag-specific germinal center B cells and serum immunoglobulin levels were significantly decreased. Hence, we postulate that alterations to the production of extracellular matrix, as seen in various connective tissue disorders, may in the end affect the qualitative outcome of adaptive immunity.

    The unplanned urbanization in Jordan has over time created many informal settlements "slums" around big cities as Amman, Zerka and Aqaba. The purpose of this study was to highlight the most common challenges related to social determinants of health in two selected slum areas in Amman and Aqaba and suggest policy directions and interventions to meet these challenges. In addition to a prestructured interview with all household heads living in the two slum sites, focus group meetings with a purposefully selected sample of 12 slum dwellers in each site were used to assess the structural and intermediary determinants of health as perceived by slum residents in the two study locations. The study found that slum residents in the two locations suffer from many challenges as severe poverty; unemployment; illiteracy and low education attainments; gender discrimination; insufficient and poor diet; social and official exclusion; unhealthy environment; lack of water supply, electricity and basic sanitation facilities; high prevalence of diseases; and insufficient and inappropriate health services. Specific policy directions to meet these challenges were recommended and grouped into three main clusters: social protection, social inclusion and empowerment. New plans and tools should be developed by local authorities in Jordan to understand, protect, include and empower those vulnerable people who are forced to live in these unhealthy and inhuman environments.

    Full Text Available The return on investment can be divided in capital gain and dividend payouts. It is a difficult task for management to allocate a sufficient amount in both segments, especially to prevent from agency problems. The firms pay dividends only when enough amounts have after meeting their requirements and short term needs. The purpose of the present study is to empirically investigate the factors determine the dividend payout decisions in the case of Pakistan’s engineeringsector by using the data of thirty-six firms listed on Karachi Stock Exchange from the period 1996 to 2008. By employing various panel data techniques like fixed and random effects, the results suggest that the previous dividend per share, earnings per share, profitability, cash flow, sales growth, and size of the firm are the most critical factors determining dividend policy in the engineering sector of Pakistan.

    Improving health requires changes in the social, physical, economic and political determinants of health behavior. For the realization of policies that address these environmental determinants, intersectoral policy networks are considered necessary for the pooling of resources to implement different policy instruments. However, such network diversity may increase network complexity and therefore hamper network performance. Network complexity may be reduced by network management and the provision of financial resources. This study examined whether network diversity - amidst the other conditions - is indeed needed to address environmental determinants of health behavior. We included 25 intersectoral policy networks in Dutch municipalities aimed at reducing overweight, smoking, and alcohol/drugs abuse. For our fuzzy set Qualitative Comparative Analysis we used data from three web-based surveys among (a) project leaders regarding network diversity and size (n = 38); (b) project leaders and project partners regarding management (n = 278); and (c) implementation professionals regarding types of environmental determinants addressed (n = 137). Data on budgets were retrieved from project application forms. Contrary to their intentions, most policy networks typically addressed personal determinants. If the environment was addressed too, it was mostly the social environment. To address environmental determinants of health behavior, network diversity (>50% of the actors are non-public health) was necessary in networks that were either small (policy networks in improving health behaviors by addressing a variety of environmental determinants.

    In recent years, Ireland has experienced a large-scale, outward migration of doctors. This presents a challenge for national policy makers and workforce planners seeking to build a self-sufficient medical workforce that trains and retains enough doctors to meet demand. Although, traditionally, medical migration has been considered beneficial to the Irish health system, austerity has brought a greater level of uncertainty to the health system and, with it, a need to reappraise the professional culture of migration and its impact on the Irish health system. This paper illustrates how a culture of migration informs career and migration plans. It draws on quantitative data-registration and migration data from source and destination countries-and qualitative data-in-depth interviews with 50 doctors who had undertaken postgraduate medical training in Ireland. Of 50 respondents, 42 highlighted the importance of migration. The culture of medical migration rests on two assumptions-that international training/experience is beneficial to all doctors and that those who emigrate will return to Ireland with additional skills and experience. This assumption of return is challenged by a new generation of doctors whose professional lives have been shaped by globalisation and by austerity. Global comparisons reveal the comparatively poor working conditions, training and career opportunities in Ireland and the relative attractiveness of a permanent career abroad. In light of these changes, there is a need to critically appraise the culture of medical migration to determine if and in what circumstances migration is appropriate to the needs of the Irish health system. The paper considers the need to reappraise the culture of medical migration and the widespread emigration that it promotes.

    Full Text Available The paper focuses on the topic of the impact of Information and Communication Technologies (ICT on the international migration phenomenon According to the discussed literature, there is an impression that ICTs change the essence of migration and monitoring of migration flows. It also suggests that migration and migrants’ needs shape the development of ICT services intended to them, but they also shape the content of social media. The impact of new technologies on international migration (before migration, during migration and upon arrival in the country of destination has been discussed through an overview of empirical research findings in Serbia and other countries. In this context, the ICT users relevant to the migration process (individuals and interest groups have been more closely determined and discussed, the aspects of the relations between ICTs and migration have been highlighted, as well as their implications for individuals and society. The considered aspects of relations of ICTs and international migration at different stages of the migration process and their severe implications for individuals and society, in our opinion, point to the need for cooperation of users of information and communication technologies relevant to the migration process in different domains ‒ the spheres of influence of ICTs. We believe that is how the potential of ICTs will be exploited in an adequate way, for benefit of both ‒ migrants and other relevant interested parties. While widely accepted by individuals, information and communication technologies have just begun to be recognized as important for migration policy in Serbia and generally, in terms of their opportunities and challenges. In Serbia, only recently (as of the 2011 Census there has been data available on the use of ICTs by certain migrant groups (long-term settled refugees from former Yugoslav republics. Also, the qualitative surveys on the use of ICTs during the migration by transit

    The interaction behavior of humic acids with uranium(VI) and the influence of humic substances on the migration behavior of uranium was investigated. A main focus of this work was the synthesis of four different humic acid model substances and their characterization and comparison to the natural humic acid from Aldrich. A radiometric method for the determination of humic acid functional groups was applied in addition to conventional methods for the determination of the functionality of humic acids. The humic acid model substances show functional and structural properties comparable to natural humic acids. Modified humic acids with blocked phenolic OH were synthesized to determine the influence of phenolic OH groups on the complexation behavior of humic acids. A synthesis method for 14 C-labeled humic acids with high specific activity was developed. The complexation behavior of synthetic and natural humic acids with uranium(VI) was investigated by X-ray absorption spectroscopy, laser-induced fluorescence spectroscopy and FTIR spectroscopy. The synthetic model substances show an interaction behavior with uranium(VI) that is comparable to natural humic acids. This points to the fact that the synthetic humic acids simulate the functionality of their natural analogues very well. For the first time the influence of phenolic OH groups on the complexation behavior of humic acids was investigated by applying a modified humic acid with blocked phenolic OH groups. The formation of a uranyl hydroxy humate complex was identified by laserspectroscopic investigations of the complexation of Aldrich humic acid with uranium(VI) at pH7. The migration behavior of uranium in a sandy aquifer system rich in humic substances was investigated in column experiments. A part of uranium migrates non-retarded through the sediment, bound to humic colloids. The uranium migration behavior is strongly influenced by the kinetically controlled interaction processes of uranium with the humic colloids

  7. US Nuclear Non-Proliferation Policy: impact on exports and nuclear industry could not be determined

    The Nuclear Non-Proliferation Act of 1978 established new measures to prevent the diversion to weapons use of peaceful nuclear exports. It also created a policy to confirm US reliability as a nuclear supplier. GAO did not identify any export sales lost as a result of the Act, but did find indications that nonprofileration policies can influence export sales. Based on avavailable data, GAO could not determine the impact of the Act on the competitiveness of US nuclear exports. However, US companies are at some disadvantage because importers perceive that implementation of the Act may result in delayed export licenses. The United States dominated the nuclear export market through the early 1970s. However, foreign competitors, some aided by US technology transfers, emerged to monopolize home markets and complete for third-country business. Further, the market has been depressed since 1974 and prospects for US nuclear power plant exports have dimmed greatly. However, US companies continue to view exports as important to sustain production capacity

    Full Text Available Cultural phenomena and processes in the contemporary society, influenced by the social development models and by the fact that the constitutive elements of the culture have become the decisive factors of social change, are the determinants of the cultural policies. They are centered on the active process of cultural globalization that emphasizes besides the assimilation of the European principles, also the preservation of the cultural dialog without identity loss. Contemporary culture cannot be appreciated unless we know the main processes and phenomena that lately have generated impressive changes in the area of technology and means of communication. Due to these transformations we witness a change of the cultural paradigms, a mutation of values.

    Full Text Available Nowadays, assuring the security of the national cyber-space has become a big issue that can only be tackled through collaborative approaches. Threats cannot be confined to a single computer system just as much as computer systems are rendered useless without being con-nected to a supporting network. The authors of this article propose an innovative architecture of a system designated to help governments collect and analyze data about cyber-security in-cidents, from different organizations, dispersed nationwide, and acting within various economic sectors. The collected data will make us able to determine a national cyber-security alert score that could help policy makers in establishing the best strategies for protecting the national cyber-space.

    In this paper, optimal environmental policy for reclamation of land unearthed in lignite mines is defined as a strategic target. The tactics concerning the achievement of this target, includes estimation of optimal time lag between each lignite site (which is a segment of the whole lignite field) complete exploitation and its reclamation. Subsidizing of reclamation has been determined as a function of this time lag and relevant implementation is presented for parameter values valid for the Greek economy. We proved that the methodology we have developed gives reasonable quantitative results within the norms imposed by legislation. Moreover, the interconnection between strategy and tactics becomes evident, since the former causes the latter by deduction and the latter revises the former by induction in the time course of land reclamation.

    The widespread use of flame retardants (FRs) in indoor products has led to their ubiquitous distribution within indoor microenvironments with many studies reporting concentrations in indoor air and dust. Little information is available however on emission of these compounds to air, particularly the measurement of specific emission rates (SERs), or the migration pathways leading to dust contamination. Such knowledge gaps hamper efforts to develop understanding of human exposure. This review summarizes published data on SERs of the following FRs released from treated products: polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDs), tetrabromobisphenol-A (TBBPA), novel brominated flame retardants (NBFRs) and organophosphate flame retardants (PFRs), including a brief discussion of the methods used to derive these SERs. Also reviewed are published studies that utilize emission chambers for investigations/measurements of mass transfer of FRs to dust, discussing the chamber configurations and methods used for these experiments. A brief review of studies investigating correlations between concentrations detected in indoor air/dust and possible sources in the microenvironment is included along with efforts to model contamination of indoor environments. Critical analysis of the literature reveals that the major limitations with utilizing chambers to derive SERs for FRs arise due to the physicochemical properties of FRs. In particular, increased partitioning to chamber surfaces, airborne particles and dust, causes loss through “sink” effects and results in long times to reach steady state conditions inside the chamber. The limitations of chamber experiments are discussed as well as their potential for filling gaps in knowledge in this area.

    Public health obesity prevention experts have recently emphasized a policy systems and environmental change approach. Absent, however, are studies describing how practitioners transition from policy adoption to implementation. In the realm of food policy, financing programs to incentivize healthy food retail development in communities classified as “underserved” are underway at the local, state, and national levels. Implementing these policies requires a clear definition of eligibility for program applicants and policy administrators. This article outlines a methodology to establish eligibility for healthy food financing programs by describing the work of The Food Trust to coadminister programs in 3 distinct regions. To determine program eligibility, qualitative assessments of community fit are needed and national data sources must be locally verified. Our findings have broad implications for programs that assess need to allocate limited public/private financing resources. PMID:24594793

  16. Characterization of molecular determinants of the conformational stability of macrophage migration inhibitory factor: leucine 46 hydrophobic pocket.

    Directory of Open Access Journals (Sweden)

    Farah El-Turk

    Full Text Available Macrophage Migration Inhibitory Factor (MIF is a key mediator of inflammatory responses and innate immunity and has been implicated in the pathogenesis of several inflammatory and autoimmune diseases. The oligomerization of MIF, more specifically trimer formation, is essential for its keto-enol tautomerase activity and probably mediates several of its interactions and biological activities, including its binding to its receptor CD74 and activation of certain signaling pathways. Therefore, understanding the molecular factors governing the oligomerization of MIF and the role of quaternary structure in modulating its structural stability and multifunctional properties is crucial for understanding the function of MIF in health and disease. Herein, we describe highly conserved intersubunit interactions involving the hydrophobic packing of the side chain of Leu46 onto the β-strand β3 of one monomer within a hydrophobic pocket from the adjacent monomer constituted by residues Arg11, Val14, Phe18, Leu19, Val39, His40, Val41, Val42, and Pro43. To elucidate the structural significance of these intersubunit interactions and their relative contribution to MIF's trimerization, structural stability and catalytic activity, we generated three point mutations where Leu46 was replaced by glycine (L46G, alanine (L46A and phenylalanine (L46F, and their structural properties, stability, oligomerization state, and catalytic activity were characterized using a battery of biophysical methods and X-ray crystallography. Our findings provide new insights into the role of the Leu46 hydrophobic pocket in stabilizing the conformational state of MIF in solution. Disrupting the Leu46 hydrophobic interaction perturbs the secondary and tertiary structure of the protein but has no effect on its oligomerization state.

    Abstracts: The Korean government adopted “green growth” in 2008 as an environmentally friendly growth strategy. The energy efficiency of Korea, however, is still relatively low due to the large portion of energy intensive industry (EII) in its manufacturing sector. To improve energy efficiency in Korea, from an EII perspective a new approach has to be taken because restructuring entire industries would take too much time and be too costly. This study aims to emphasize the importance of innovation and analyze the effects of R&D on product and process innovations in EII in Korea. The Probit model is adopted to estimate the effects of eight determinants in the Korea Innovation Survey 2008 data. The results of this study demonstrate that one of the most important determinants, the R&D personnel ratio, has a strong positive effect on both product and process innovation, while another determinant, R&D intensity, only has a strong and positive effect on process innovation in EII. Because of the resulting innovation, energy policies should be enacted to enhance energy efficiency. Thus, the Korean government should keep providing incentives for firms in EII to invest more financial and human resources in their R&D activities. -- Highlights: •We analyze determinants on two innovations in energy intensive industry (EII). •The R&D personnel ratio is effective in product innovation in EII. •Both R&D intensity and R&D personnel are effective in process innovation in EII. •In less EII, R&D variables have positive effects on product and process innovations. •The Korean government should strongly support R&D to improve energy efficiency

    The migration of melamine monomers from food contact materials has aroused particular attention since the 2008 melamine-tainted milk scandal in China. However, the determination of melamine monomer's migratory quantity (MMMQ) has remained an open question because of the complex sample pretreatment and the low sensitivity. Based on the hydrogen bonding interaction between DNA thymine and melamine, this paper described a simple and rapid method focusing on the measurement of MMMQ from melamine tableware by gold nanoparticles (GNPs) and dynamic light scattering (DLS). With the presence of probe DNA (p-DNA), the GNPs were stable in NaCl solution (0.06 M), whereas they became aggregated when the p-DNA hybridized with melamine. The change in the hydrodynamic diameter of GNPs could be detected by DLS technology. Under the optimal conditions, the average diameter increased linearly with the concentration of melamine over the range from 5.0 to 320.0 μg L(-1), and showed a detection limit of 2.0 μg L(-1) (3σ/slope). The MMMQ was investigated within a range from 6.00×10(-4) to 2.58×10(-1) mg dm(-2) (n≥3) in four different food simulants at different temperatures and time points. The results suggest that the DLS method has great potential in the analysis of the migration of melamine monomers. Copyright © 2014 Elsevier B.V. All rights reserved.

    Migration chemistry, the influence of chemical -, biochemical - and physico-chemical reactions on the migration behaviour of pollutants in the environment, is an interplay between the actual natur of the pollutant and the characteristics of the environment, such as pH, redox conditions and organic matter content. The wide selection of possible pollutants in combination with varying geological media, as well as the operation of different chemical -, biochemical - and physico-chemical reactions compleactes the prediction of the influence of these processes on the mobility of pollutants. The report summarizes a wide range of potential pollutants in the terrestrial environment as well as a variety of chemical -, biochemical - and physico-chemical reactions, which can be expected to influence the migration behaviour, comprising diffusion, dispersion, convection, sorption/desorption, precipitation/dissolution, transformations/degradations, biochemical reactions and complex formation. The latter comprises the complexation of metal ions as well as non-polar organics to naturally occurring organic macromolecules. The influence of the single types of processes on the migration process is elucidated based on theoretical studies. The influence of chemical -, biochemical - and physico-chemical reactions on the migration behaviour is unambiguous, as the processes apparently control the transport of pollutants in the terrestrial environment. As the simple, conventional K D concept breaks down, it is suggested that the migration process should be described in terms of the alternative concepts chemical dispersion, average-elution-time and effective retention.

    2004-06-01

    Little is known of the structure of the international migration of skilled health professionals. Accelerated migration of doctors and nurses from the Pacific island states of Fiji, Samoa and Tonga to the Pacific periphery is part of the globalization of health care. The findings from a recent survey of 251 doctors and nurses from the three island countries are reported here. Key determinants of both present migration status and future migration intentions were analyzed using econometric methods. Nurses' and doctors' propensities to migrate are influenced by both income and non-income factors, including ownership of businesses and houses. Migrants also tend to have more close relatives overseas, to have trained there, and so experienced superior working conditions. Migration propensities vary between countries, and between nurses and doctors within countries. Tongan nurses have a higher propensity to migrate, mainly because of greater relative earnings differentials, but are also more likely to return home. The role of kinship ties, relative income differentials and working conditions is evident in other developing country contexts. Remittances and return migration, alongside business investment, bring some benefits to compensate for the skill drain. National development policies should focus on encouraging return migration, alongside retention and recruitment, but are unlikely to prevent out migration.

    Elucidating the key impact factors on PM 2.5 concentrations is crucial to formulate effective mitigation policies. In this study, we employed an extended Stochastic Impacts by Regression on Population Affluence and Technology (STIRPAT) model to identify the socioeconomic determinants of PM 2.5 concentrations for 12 different regions and across China. The evaluation was based on a balanced panel dataset integrating long-term satellite-derived PM 2.5 concentrations and socio-economic data in China from 1999 to 2011. Empirical results indicate that the influencing factors can be ranked in descending order of importance as: proportion of secondary sector of the economy, GDP per capita, urbanization, population, energy intensity, and proportion of tertiary sector. Proportion of secondary sector is the greatest contribution to increasing PM 2.5 concentrations, especially for heavily polluted regions. GDP per capita is secondary in importance, and its impact is weakened by the existence of an EKC relationship between GDP per capita and PM 2.5 concentrations. Therefore, PM 2.5 pollution is an economic development mode problem, rather than a general economic development problem. The impact of urbanization varies across regions; while promoting urbanization will be conducive to decreased PM 2.5 concentrations in Northwest China and Northeast China, it will contribute to increased PM 2.5 concentrations in other regions. Population and energy intensity are significant in most regions, but neither are decisive factors because of the small absolute value of their coefficients. Finally, different combinations of mitigation policies are proposed for different regions in this study to meet the mitigation targets. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Full Text Available The primary aim of this study is to assess the actual impact of healthcare public financing on population health status, while controlling for other non-financial health determinants. There are plenty of heterogeneous studies dealing with the negative or positive effects of different products consumption (e.g. sugar, alcohol, tobacco, fruits, vegetables, etc. on people’s health. Starting from the relevant ones, we kept for our models those non-financial variables with public available data, used as control variables. After performing variable selection, we ranked the actual impact of different public expenditures categories on health status change, using simple and multiple regression fixed-effects techniques on a panel dataset regarding the European members of OECD (ranging from 1970 to 2014. Our results show that financing preventive care has the strongest positive impact on the health status, followed by auxiliary (ancillary services. Administrative expenditures for the healthcare system do not have a significant influence, suggesting there is available room to enhance the effectiveness and performance of sanitary institutions management. Our results also show that life expectancy is negatively affected by the consumption of alcohol and sugar, in a decreasing order. These results were then connected with Romanian realities regarding health care financing and people’s consumption habits. In strong connection with our findings and these realities, this study provides, as a final part, a set of policy recommendations useful for Romanian public authorities in designing their policies, as well as for other interested non-governmental actors.

  3. The Evolution of Renewable Energy Policy in OECD Countries: aggregate indicators and determinants

    2012-04-01

    This paper proposes different methods to aggregate heterogeneous policies for renewable energy. We compare time-varying indicators built using principal component analysis with average-based indicators. The main goal of the paper is to account for the evolution of both types of policy indicators with a set of common variables. Our empirical results are consistent with predictions of political-economy models of environmental policies as lobbying, income and, to a less extent, inequality have expected effects on policy. The brown lobbying power, proxied by entry barriers in the energy sector, has negative influence on the policy indicators even when taking into account endogeneity in its effect. The results are also robust to dynamic panel specifications and to the exclusion of groups of countries. Interestingly, too, corruption has only an indirect effect on policy mediated by entry barriers, while the negative effect of inequality is much stronger for the richer countries. (authors)

    1981-01-01

    A method of U and Th isotope ratio determination by α-spectroscopy to analyse the migration process of these elements at an uranium bearing region in Goias, Brazil, is described. The method consists of simultaneous extraction of U and Th with TOPO/cyclohexane, reextraction of Th with H 2 SO 4 (0.3M) and further purification of both phases. The interferent coextracted ions are eliminated by scrubbing with EDTA/NaNO 3 , and pure U is extracted with (NH 4 ) 2 CO 3 . The counting sources are prepared via extraction with TTA or MIBK, and evaporation of suitable aliquots on stainless steel disks. The recovery of U about 98% is obtained. The energy resolutions of U 238 peak (E α =4.195 MeV) are 52 and 83 KeV. The counting efficiencies are between 11 and 21+. Th is separated from the stripping solution by direct coprecipitation with macro amounts of LaF 3 and subsequent extraction with TTA/benzene for source preparation. Alternatively coprecipitation is proposed with micro quantities of LaF 3 and posterior filtration with membrane filters, where LaF 3 layer was previously deposited. This method allows direct counting of the filters and is superior in relation to energy resolution and counting efficiency. The U 238 /U 234 and U 234 /Th 230 isotope ratios in geological standards and prospecting samples were determined. The U 234 /Th 230 isotope ratio was used for analysing the migration of these elements because the most of analysed samples presented values, for this ratio, greater than unity, indicating that the anomalous concentrations of U are due to secondary enrichment processes. Aditional results of non equilibrium of the radioactivity of samples by γ-spectroscopy, are presented. (author) [pt

General expenditure on research and development in Spain is far from the Organisation for Economic Co-operation and Development mean. In addition, both globally and within Spain, the scientific production on health inequalities is very low, especially compared with other research areas. The budget for research on health inequalities is also reduced. A striking example is provided by analysis of the projects funded by the Marató de TV3, which seems to have little interest in funding research on health inequalities. However, both the scientific production and project financing on health inequalities have increased in the last decade. Finally, to advance research on health inequalities and its contribution to the incorporation of health in all policies, recommendations are made, which include redefining priorities, ensuring resources and promoting knowledge translation.

  6. Repeat migration and disappointment.

    Grant, E K; Vanderkamp, J

    1986-01-01

    This article investigates the determinants of repeat migration among the 44 regions of Canada, using information from a large micro-database which spans the period 1968 to 1971. The explanation of repeat migration probabilities is a difficult task, and this attempt is only partly successful. May of the explanatory variables are not significant, and the overall explanatory power of the equations is not high. In the area of personal characteristics, the variables related to age, sex, and marital status are generally significant and with expected signs. The distance variable has a strongly positive effect on onward move probabilities. Variables related to prior migration experience have an important impact that differs between return and onward probabilities. In particular, the occurrence of prior moves has a striking effect on the probability of onward migration. The variable representing disappointment, or relative success of the initial move, plays a significant role in explaining repeat migration probabilities. The disappointment variable represents the ratio of actural versus expected wage income in the year after the initial move, and its effect on both repeat migration probabilities is always negative and almost always highly significant. The repeat probabilities diminish after a year's stay in the destination region, but disappointment in the most recent year still has a bearing on the delayed repeat probabilities. While the quantitative impact of the disappointment variable is not large, it is difficult to draw comparisons since similar estimates are not available elsewhere.

  7. MIGRATION IMPACT ON ECONOMICAL SITUATION

    Full Text Available This paper presents recent trends and flows of labor migration and its impact on economic and social life. Main aim of this research sets up the influence of the migration on the European economics and its competitiveness. Methods of research are: method of comparison, analysis method, method of deduction, method of statistics, modeling method. The economic impact of migration has been intensively studied but is still often driven by ill-informed perceptions, which, in turn, can lead to public antagonism towards migration. These negative views risk jeopardising efforts to adapt migration policies to the new economic and demographic challenges facing many countries. Migration Policy looks at the evidence for how immigrants affect the economy in three main areas: The labour market, public purse and economic growth. In Europe, the scope of labour mobility greatly increased within the EU/EFTA zones following the EU enlargements of 2004, 2007 and 2014-2015. This added to labour markets’ adjustment capacity. Recent estimates suggest that as much as a quarter of the asymmetric labour market shock – that is occurring at different times and with different intensities across countries – may have been absorbed by migration within a year.

  8. Indonesia's migration transition.

    This article describes population movements in Indonesia in the context of rapid and marked social and economic change. Foreign investment in Indonesia is increasing, and global mass media is available to many households. Agriculture is being commercialized, and structural shifts are occurring in the economy. Educational levels are increasing, and women's role and status are shifting. Population migration has increased over the decades, both short and long distance, permanent and temporary, legal and illegal, and migration to and between urban areas. This article focuses specifically on rural-to-urban migration and international migration. Population settlements are dense in the agriculturally rich inner areas of Java, Bali, and Madura. Although the rate of growth of the gross domestic product was 6.8% annually during 1969-94, the World Bank ranked Indonesia as a low-income economy in 1992 because of the large population size. Income per capita is US $670. Indonesia is becoming a large exporter of labor to the Middle East, particularly women. The predominance of women as overseas contract workers is changing women's role and status in the family and is controversial due to the cases of mistreatment. Malaysia's high economic growth rate of over 8% per year means an additional 1.3 million foreign workers and technicians are needed. During the 1980s urban growth increased at a very rapid rate. Urban growth tended to occur along corridors and major transportation routes around urban areas. It is posited that most of the urban growth is due to rural-to-urban migration. Data limitations prevent an exact determination of the extent of rural-to-urban migration. More women are estimated to be involved in movements to cities during the 1980s compared to the 1970s. Recruiters and middlemen have played an important role in rural-to-urban migration and international migration.

    "The functions of migration are reviewed from the viewpoint of the demographic situation in the USSR (by regions, sex, age, education, profession, labour and social activity, nationality, rural-urban, etc.). Some effects of migration on fertility are shown. The authors investigate the role of the economic functions of migration for the process of professional mobility. The territorial mobility of the population is analysed on a wider scale as a part of the social mobility in the socialist society. In connection with this, some problems of the migration policy as an element of the demographic policy of the USSR are outlined." (summary in ENG, RUS) excerpt

    Background For health technology assessment (HTA) to be more policy relevant and for health technology-related decision-making to be truly evidence-based, promoting knowledge translation (KT) is of vital importance. Although some research has focused on KT of HTA, there is a dearth of literature on KT determinants and the situation in developing countries and transitional societies remains largely unknown. Objective To investigate the determinants of HTA KT from research to health policy-making from the perspective of researchers in China. Design Cross-sectional study. Methods A structured questionnaire which focused on KT was distributed to HTA researchers in China. KT activity levels in various fields of HTA research were compared, using one-way ANOVA. Principal component analysis was performed to provide a basis to combine similar variables. To investigate the determinants of KT level, multiple linear regression analysis was performed. Results Based on a survey of 382 HTA researchers, it was found that HTA KT wasn’t widespread in China. Furthermore, results showed that no significant differences existed between the various HTA research fields. Factors, such as attitudes of researchers toward HTA and evidence utilization, academic ranks and linkages between researchers and policy-makers, had significant impact on HTA KT (p-valuespolicy-makers, policy-relevance of HTA research, practicality of HTA outcomes and making HTA reports easier to understand also contributed to predicting KT level. However, academic nature of HTA research was negatively associated with KT level. Conclusion KT from HTA to policy-making was influenced by many factors. Of particular importance were collaborations between researchers and policy-makers, ensuring policy relevance of HTA and making HTA evidence easier to understand by potential users. PMID:29300753

    A major portion of migration flows are temporary, ending with return migration to the home country or migration to a third country. However, the propensity to return differs according to migrants' countries of origin. This paper presents a discussion of the theoretical approaches to return...... migration and a brief survey of the actual flows in Denmark. We then present a panel data set of immigrants to Denmark covering the years 1986 - 1995 and run a number of logit models where return migration is related to individual background factors. Our research shows significant differences in decisions...... of return depending on country of origin, age at entry, education, and family ties. One of the most important determinants is found to be a migrant's success, or lack thereof, regarding labour market integration. This research suggests that policy instruments such as education, training, and temporary wage...

  14. Acknowledging individual responsibility while emphasizing social determinants in narratives to promote obesity-reducing public policy: a randomized experiment.

    Niederdeppe, Jeff; Roh, Sungjong; Shapiro, Michael A

    2015-01-01

    This study tests whether policy narratives designed to increase support for obesity-reducing public policies should explicitly acknowledge individual responsibility while emphasizing social, physical, and economic (social) determinants of obesity. We use a web-based, randomized experiment with a nationally representative sample of American adults (n = 718) to test hypotheses derived from theory and research on narrative persuasion. Respondents exposed to narratives that acknowledged individual responsibility while emphasizing obesity's social determinants were less likely to engage in counterargument and felt more empathy for the story's main character than those exposed to a message that did not acknowledge individual responsibility. Counterarguing and affective empathy fully mediated the relationship between message condition and support for policies to reduce rates of obesity. Failure to acknowledge individual responsibility in narratives emphasizing social determinants of obesity may undermine the persuasiveness of policy narratives. Omitting information about individual responsibility, a strongly-held American value, invites the public to engage in counterargument about the narratives and reduces feelings of empathy for a character that experiences the challenges and benefits of social determinants of obesity.

    Leaching and transport of radionuclides by water has been a primary mode of radioactive contamination from low-level radioactive waste disposal facilities. Similarly, the infiltration of water into nonradioactive hazardous waste disposal facilities has resulted in the movement of contaminants out of these disposal facilities. Although there have been many laboratory studies on water movement and contaminant transport, there is a need for more large scale field experiments. Large scale field experiments are necessary to (1) measure hydraulic conductivities on a scale typical of actual shallow land burial facilities and hazardous waste disposal facilities, (2) allow comparisons to be made between full scale and laboratory measurements, (3) verify the applicability of calculational methods for determining unsaturated hydraulic conductivities from water retention curves, and (4) for model validation. Experiments that will provide the information to do this are described in this paper

    Currently, villages "besieged with garbage" have become a serious problem in rural areas of China. Separation of rural residential solid waste (RRSW) is one of the main strategies for waste reduction. Although previous studies have analyzed the social and psychological motivations of residents' separation intention for municipal solid waste (MSW), little attention has been paid to the situation in rural areas. This paper investigates key factors influencing rural residents' separation intention, as well as analyzing the moderating effects of perceived policy effectiveness on the relationship between the determinants and the intention, using survey data of 538 rural residents in the province of Sichuan in China. The results show that all the proposed key factors influence the separation intention significantly. Furthermore, the policies were divided into two types and the moderating effects were tested for each type. The results show that the perceived effectiveness of both the inducement policy and the capacity building policy moderated the relationship between attitude and separation intention positively, while the perceived effectiveness of the inducement policy moderated the relationship between subjective norms and intention negatively. The findings provide insightful information for policymakers to design effective RRSW separation policies.

  1. Façade insulation retrofitting policy implementation process and its effects on health equity determinants: A realist review

    Fuel poverty and cold housing constitute a significant public health problem. Energy efficiency interventions, such as façade retrofitting, address the problem from a structural and long-term perspective. Despite evidence of the health benefits of insulation, little is known about the political and social contexts that contribute to social inequalities in receiving and experiencing health benefits from these interventions. We used a realist review methodology to better understand the mechanisms that explain how and why variations across different social groups appear in receiving energy efficiency façade retrofitting interventions and in their impact on health determinants. We considered the four stages of the policy implementation framework: public policy approach; policy; receiving intervention and impact on health determinants. We found strong evidence that certain social groups (low-income, renters, elderly) suffering most from fuel poverty, experience more barriers for undertaking a building retrofitting (due to factors such as upfront costs, “presentism” thinking, split incentives, disruption and lack of control), and that some public policies on housing energy efficiency may exacerbate these inequalities. This can be avoided if such policies specifically aim at tackling fuel poverty or social inequities, are completely free to users, target the most affected groups and are adapted to their needs. - Highlights: •Health benefits of housing façade insulation more pronounced in fuel poor groups. •Social groups suffering most from fuel poverty least likely to undergo insulation. •Energy efficiency policies focused solely on CO_2 reduction may increase inequalities. •Split Incentives and “Take-Back” effect show socioeconomic and contextual variability. •Universal policies without targeting increase inequalities in retrofitting uptake.

    "Emigration pressures are primarily the result of increasing inequalities between countries which, in turn, are the result of factors internal to less developed countries and their relations with developed countries. Both micro (neoclassical) and macrostructural theories of migration are reviewed. It is argued that the neoclassical theory of migration is often unjustly criticized and is sufficiently robust to incorporate those structural considerations which are at the core of macrostructural theories. Moreover, the neoclassical theory, with slight modification, can incorporate the ¿new economics of migration.' The major empirical problem confronting models of international labor migration is that migration flows are constrained by immigration policy. This policy, in turn, is influenced by various special interest groups. The direction and form of migration flows is conditioned by contemporary and historical relationships between source and destination countries." excerpt

    The concept of brain death (BD), defined as irreversible loss of function of the brain including the brainstem, is accepted in the medical literature and in legislative policy worldwide. However, in most of Sub-Saharan Africa (SSA) there are no legal guidelines regarding BD. Hypothetical scenarios based on our collective experience are presented which underscore the consequences of the absence of BD policies in resource-limited countries (RLCs). Barriers to the development of BD laws exist in an RLC such as Kenya. Cultural, ethnic, and religious diversity creates a complex perspective about death challenging the development of uniform guidelines for BD. The history of the medical legal process in the USA provides a potential way forward. Uniform guidelines for legislation at the state level included special consideration for ethnic or religious preferences in specific states. In SSA, medical and social consensus on the definition of BD is a prerequisite for the development BD legislation. Legislative policy will (1) limit prolonged and futile interventions; (2) mitigate the suffering of families; (3) standardise clinical practice; and (4) facilitate better allocation of scarce critical care resources in RLCs. There is a clear-cut need for these policies, and previous successful policies can serve to guide these efforts.

  6. Current Migration Movements in Europe

    2004-09-01

    Full Text Available After a brief historical review of migrations in Europe, the paper focuses on current migration trends and their consequences. At the end of the 1950s, Western Europe began to recruit labour from several Mediterranean countries – Italy, Spain, Portugal and former Yugoslavia, and later from Morocco, Algeria, Tunisia and Turkey. Some countries, such as France, Great Britain and the Netherlands, recruited also workers from their former colonies. In 1970 Germany had the highest absolute number of foreigners, followed by France, and then Switzerland and Belgium. The total number of immigrants in Western Europe was twelve million. During the 1970s mass recruitment of foreign workers was abandoned, and only the arrival of their family members was permitted, which led to family reunification in the countries of employment. Europe closed its borders, with the result that clandestine migration increased. The year 1989 was a turning point in the history of international migrations. The political changes in Central and Eastern Europe brought about mass migration to the West, which culminated in the so-called “mass movement of 1989–1990”. The arrival of ethnic Germans in Germany, migration inside and outside of the territory of the former Soviet Union, an increase in the number of asylum seekers and displaced persons, due to armed conflicts, are – according to the author – the main traits of current migration. The main part of the paper discusses the causes and effects of this mass wave, as well as trends in labour migration, which is still present. The second part of the paper, after presenting a typology of migrations, deals with the complex processes that brought about the formation of new communities and led to the phenomenon of new ethnic minorities and to corresponding migration policies in Western European countries that had to address these issues.

    Full Text Available This study examines the patterns of Chinese migration to and from Vietnam as well as the demographic changes relating to the Chinese residing in the country. It also outlines how the French authorities responded to the arrival of the Chinese and how they treated them. The focus is on the period of French control over the whole of Vietnam from 1883 to 1954. The French authorities did pay considerable attention to the Chinese migration to Vietnam. The policies of the French aimed at keeping a close surveillance on the Chinese. To administer the Chinese communities the French opted to maintain the system of indirect control introduced by the Vietnamese Emperors. During the period of French rule the Chinese population grew considerably. Chinese migration to and from Vietnam was influenced by the political evolution in China and by repercussions of international economic developments. Thus, the French authorities could influence the migrants when they arrived or departed, but the decision to migrate was primarily due to other factors.Cette étude examine les modèles de la migration chinoise à destination et en provenance du Viêt Nam de même que les changements démographiques concernant les Chinois résidant dans le pays.

  10. Myanmar’s China Policy since 2011: Determinants and Directions

    Directory of Open Access Journals (Sweden)

    Maung Aung Myoe

    2015-01-01

    Full Text Available This paper argues that a key factor in Myanmar’s new approach towards China since 2011 has been the Myanmar government’s foreign policy goal to reintegrate itself into the international community. The success of this approach is dependent on Myanmar’s rapprochement with the United States, which requires both domestic political reforms and a foreign policy realignment – a need to reduce Myanmar’s dependence on China, particularly in the context of US–China strategic competition in the Indo-Pacific region. In the context of China–Myanmar relations, the factors that have influenced Myanmar’s China policy since 2011 are growing anti-China sentiment in Myanmar, growing concern over China’s interference in Myanmar affairs, and the rapprochement with the United States. Myanmar’s China policy shift, in terms of direction, is by no means to seek to be independent of China, but rather for there to be an increased interdependence between the two countries.

    1996-01-01

    The dispersion of a 51 TBq 137 Cs source to the environment in Goiania city, has originated approximately 3500 m 3 of radioactive waste. In order to segregate such waste in a definite form, a repository is being built in Abadia de Goias, GO near the site where it has been temporarily stored. This study had the following objectives: the determination of the 137 Cs partition rate (K D ) and the estimate of its migration velocity in soil samples from the site where the repository is being built. The determination of 137 Cs K D was carried out by using two methods: 'batch method' and 'in-situ' method. In relation to the 'batch method'; 6 soil profiles cut into sections according to its pedologic horizons and 13 surface soil samples were collected, whereas for the 'in-situ' method 6 soil profiles with 28 cm depth were collected and each profile has been cut into 14 soil sections of a 1-3 cm range. Studies were carried out by using the 'batch method' to relate the influence from v/m and from shaking in K D determination and also studies about 137 Cs adsorption reversibility in soil, time necessary for the equilibrium of 137 Cs between water/soil phases to be reached and K D correlation with pedological parameters (pH values in water and clay, silt and organic material percent concentration, electrical conductivity of solution and the cation exchange - Ca +2 , Mg +2 , K +2 , Na + , Al +3 , H + ). It has been noticed that in work conditions, K D has increased according to the rate increase v/m and the use of agitation in water/soil phases had no influence in K D determination. The absorbed 137 Cs desorption process by water has shown to be slow but continued. Nevertheless, 137 Cs cationic exchange for NH 4 + has presented two steps: the first one very fast where approximately 50% of 137 Cs adsorbed has been exchanged for NH 4 + ions in just two days and the second one slow. Results indicate that 137 Cs adsorption process in this kind of soil may be considered reversible

    A novel solid-phase microextraction (SPME) fiber was fabricated by a porous aromatic framework 48 (PAF-48)/gel hybrid material through a sol-gel process. PAF-48 is a porous organic framework (POF) material that was polymerized from 1,3,5-triphenylbenzene. The uniform pore structure, high surface area, continuous conjugate network, and hydrophobicity make PAF-48 expected to have special abilities to absorb and extract styrene as well as some other harmful volatile aromatic compounds (VACs). The PAF-48/gel-coated fiber was explored for the extraction of styrene and six VACs (benzene, toluene, ethylbenzene, and xylenes) from aqueous food simulants followed by gas chromatography (GC) separation. The fiber was found to be very sensitive for the determination of the target molecules with wide linear ranges (0.1-200 or 500 μg·kg -1 ), low limits of detection (LODs, 0.003-0.060 μg·kg -1 ), acceptable precisions (intraday relative standard deviation, RSD 200 times). Particularly for styrene, the PAF-48/gel-coated fiber exhibited a much lower LOD (0.006 μg·kg -1 ) compared with most of the reported fibers. Moreover, the PAF-48/gel-coated fiber had a high extraction selectivity for styrene and VACs over alcohols, phenols, aromatic amines, and alkanes and show a molecular sieving effect for the different molecule sizes. Finally, the PAF-48/gel-coated SPME fiber was successfully applied in GC for the determination of the specific migrations of styrene and VACs from polystyrene (PS) plastic food contact materials (FCMs).

    Background: Despite decades of evidence gathering and calls for action, few countries have systematically attenuated health inequities (HI) through action on the social determinants of health (SDH). This is at least partly because doing so presents a significant political and policy challenge. This paper explores this challenge through a review of the empirical literature, asking: what factors have enabled and constrained the inclusion of the social determinants of health inequities (SDHI) in government policy agendas? Methods: A narrative review method was adopted involving three steps: first, drawing upon political science theories on agenda-setting, an integrated theoretical framework was developed to guide the review; second, a systematic search of scholarly databases for relevant literature; and third, qualitative analysis of the data and thematic synthesis of the results. Studies were included if they were empirical, met specified quality criteria, and identified factors that enabled or constrained the inclusion of the SDHI in government policy agendas. Results: A total of 48 studies were included in the final synthesis, with studies spanning a number of country-contexts and jurisdictional settings, and employing a diversity of theoretical frameworks. Influential factors included the ways in which the SDHI were framed in public, media and political discourse; emerging data and evidence describing health inequalities; limited supporting evidence and misalignment of proposed solutions with existing policy and institutional arrangements; institutionalised norms and ideologies (ie, belief systems) that are antithetical to a SDH approach including neoliberalism, the medicalisation of health and racism; civil society mobilization; leadership; and changes in government. Conclusion: A complex set of interrelated, context-dependent and dynamic factors influence the inclusion or neglect of the SDHI in government policy agendas. It is better to think about these factors

    Full Text Available International migration significantly affects economic, social, cultural, and political factors of the country. Owing to this situation, it can be said that the reasons of international migration should be analyzed in order to control this problem. The purpose of this study is to determine the influencing factors of international migration in Azerbaijan. In this scope, annual data of 11 explanatory variables for the period of 1995–2015 was analyzed via Multivariate Adaptive Regression Splines (MARS method. According to the results of this analysis, it was identified that people prefer to move other countries in case of high unemployment rates. In addition, the results of the study show that population growth and high mortality rate increases the migration level. While considering these results, it was recommended that Azerbaijan should focus on these aspects to control international migration problem.

    Differences in economic opportunities give rise to strong migration incentives, across regions within countries, and across countries. In this paper we focus on responses to differences in welfare benefits across States. We apply the model developed in Kennan and Walker (2008), which emphasizes that migration decisions are often reversed, and that many alternative locations must be considered. We model individual decisions to migrate as a job search problem. A worker starts the life-cycle in some home location and must determine the optimal sequence of moves before settling down. The model is sparsely parameterized. We estimate the model using data from the National Longitudinal Survey of Youth (1979). Our main finding is that income differences do help explain the migration decisions of young welfare-eligible women, but large differences in benefit levels provide surprisingly weak migration incentives.

    Previous research on the determinants of international migration has largely focused on objective factors, such as income. We instead use subjective well-being (SWB) to explain international migration desires, an expressed willingness to migrate. We find that individuals with higher SWB have lower international migration desires. At the individual level, the SWB-migration relationship appears to be more robust than the income-migration relationship. At the country level, national average SWB ...

    Migration's social value is generally assessed from the perspective of the receiving country. At this time the policies of rich countries allow fewer immigrants to enter than would enter under a laissez faire policy, but this may be a suboptimal policy for the world population as a whole. Those who now migrate from poor to rich countries and those who are prevented from doing so by restrictive laws certainly believe that their economic situation would be improved by such migration. A scheme for improving the worldwide welfare while making appropriate allowance for the preferences of those in the rich countries is discussed. The scheme deals with the migration of poorly schooled and semiskilled people and not the well educated. As the rich countries will not voluntarily open their borders to such immigration, a change in the international system is suggested, giving some power of taxation to an international body. This body would then pay the rich countries to take in immigrants by holding an auction among the rich countries for the immigration contracts. The scheme is analyzed, and it is argued that in the long run this approach is not as politically impossible as it initially seems. The discussion reviews the problem, the system, and the possibilities (the power of migration, the mechanisms in migration's power to raise productivity, earning patterns of immigrant cohorts, and additional possible tests) and the relative effectiveness of migration verses education in the less developed countries. It seems reasonable to send the migrants to countries that want them or can be made to want them, and an auction is a device to determine who wants something relative to someone else. A Supranational Planning Authority (SPA) could hold an auction at which countries would submit the price (per migrant or per migratory family) at which they will undertake the task of relocating migrants. The conditions of the contract would be specified, including the kind and location of

    2012-03-01

    An electro-osmosis experiment was set up on a former asphalt factory site, which is currently contaminated by tar, in Olst, the Netherlands. The main goal of this experiment was to remove polycyclic aromatic hydrocarbons (PAHs) from a contaminated clay layer by applying an electric gradient. But before calculating PAH removal, the direction and intensity of electro-osmosis have to be estimated. In field situations, tracers are used to get information about the water flow. In the present study, the inorganic elements concentration oscillations during electro-osmosis application are used as tracers. The experiment was set up in a clay layer, with the configuration 1m×1m×0.3m, at a depth of 4m below soil surface. Al, Ca, Cl, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P, S, Si, Ti and Zn concentrations were determined in 28 measurements and were performed during the experimental period of 159days. Then they were used in a first evaluation where auto and cross-correlations were analyzed to aid in the geochemical interpretation and select the most conservative elements. The second part of this study is devoted to estimate the migration of water based on the concentrations development of Cl - at the anode and Na + at the cathode. Electro-osmotic flow was estimated to be intense (2.9 -10 -9-2.18 -10 -8m -s -1) during the first 10 to 50days of experiment and to cease after this period. © 2012.

  2. Migration pathways in soils

    1986-01-01

    This study looked at diffusive migration through three types of deformation; the projectile pathways, hydraulic fractures of the sediments and faults, and was divided into three experimental areas: autoradiography, the determination of diffusion coefficients and electron microscopy of model projectile pathways in clay. For the autoradiography, unstressed samples were exposed to two separate isotopes, Pm-147 (a possible model for Am behaviour) and the poorly sorbed iodide-125. The results indicated that there was no enhanced migration through deformed kaolin samples nor through fractured Great Meteor East (GME) sediment, although some was evident through the projectile pathways in GME and possibly through the GME sheared samples. The scanning electron microscopy of projectile pathways in clay showed that emplacement of a projectile appeared to have no effect on the orientation of particles at distances greater than two projectile radii from the centre of a projectile pathway. It showed that the particles were not simply aligned with the direction of motion of the projectile but that, the closer to the surface of a particular pathway, the closer the particles lay to their original orientation. This finding was of interest from two points of view: i) the ease of migration of a pollutant along the pathway, and ii) possible mechanisms of hole closure. It was concluded that, provided that there is no advective migration, the transport of radionuclides through sediments containing these defects would not be significantly more rapid than in undeformed sediments.

    The focus of this article is on representations of irregular migration in a Scandinavian context and how irregular migrants are constructed as a target group. A common feature in many (Western-)European states is the difficult attempt to navigate between an urge for control and respecting......, upholding and promoting humanitarian aspects of migration management. Legitimizing policies therefore become extremely important as governments have to appease national voters to remain in power and have to respect European regulations and international conventions.

    Full Text Available The aim of the article is to reveal the influence of geo-economic transformations on the trends in international migration of human resources as an element of the resource potential of countries and regions. The current state of geo-economic transformations is analyzed, and their influence on the processes of international migration of human resources is revealed. The relevance of analyzing international movement of human resources, not labor ones, in building the geo-economic strategy of a country or a regional grouping is justified. The connection between the international migration of human resources and the trends in development of individual countries and regions (oil exporting countries, newly industrialized countries and least developed agrarian countries is determined, the general patterns of migration flows in these countries are described. Furthermore, the topical issues in studying international migration of human resources in the context of the directions of geo-economics identified by scientists are formulated. It is determined that the regional migration policy should contribute to maximizing the benefits of migration of human resources for the development of the region and the use of immigrants in the countries of the region as an economic resource that becomes strategically important under conditions of geo-economic transformations.

    This study is concerned with the welfare magnet problem, in which disparities in transfer policies across states are believed to encourage recipient and possibly resource migration. "This study clarifies the terms of the debate by showing how the value of redistributing local resources depends not only on the value of income to each group, but also on the cost of the transfer in erosion of the resource base through migration and through the general equilibrium effects of such activity on local prices." The geographical focus is on the United States. excerpt

  8. Mediterranean Migrations: Regionalisms Versus Globalisation

    Directory of Open Access Journals (Sweden)

    Martin Baldwin-Eduards

    2004-06-01

    Full Text Available This paper challenges the claim of globalisation as a cause ofimmigration into Southern Europe and, on an empirical basis, identifies regionalisation as being the primary issue, along with networked migratory patterns. However, the changing patterns of immigration do present challenges to both state and society. It is argued here that recent policy responses in Portugal, Italy and Spain have been inconsistent and irrational – reflecting more the ‘securitisation’ of migration than European reality. Earlier policy innovations are identified, by country and date: most of these have now been abandoned. It is suggested that all of Southern Europe has converged onto a statist, restrictionist model of immigration control that was formerly held only by Greece. The principal characteristics of this model are outlined, along with a migration flowchart and indicative data for migrant flows and sub-flows in Italy and Spain. In the final section, I try to show that the needs of the economy cannot be predicted, immigration cannot becontrolled in the manner currently being enforced across Southern Europe, and attempts to do so will damage rather than improve economic productivity and growth. The concept of an accomodating immigration policy is advanced, whereby the state tries to manage the needs of both employers and potential migrants. Six guidelines for policy development are suggested – most of which have alreadybeen successfully carried out in the European Union. These are the following: migration in order to find a job; circular cross-border migration; EU level negotiation of readmission agreements; the need for a variety of migration-for-employment schemes; legal residence should not depend upon continuity of employment; and discreet legalisation will still be needed in Southern Europe.

    2011-01-01

    Full Text Available This article serves as an introduction to the others published in this thematic issue of the Cadernos de Saúde Pública. The author makes a brief historical review of the concepts, approaches and methodologies used to study the relationships between social determinants and health outcomes. By analyzing the current global movement around social determinants of health he emphasizes that the distinctive feature of this movement is the explicit commitment to action through intersectoral public policies that are based on evidence and implemented with the support and participation of broad segments of society. As this special issue of the Cadernos de Saúde Pública is dedicated to presenting the results of research related to social determinants of health, the author focuses on an analysis of the difficulties in the production and use of scientific evidence that supports the definition, implementation and evaluation of policies to combat health inequities through action on social determinants of health. To conclude, he presents some recommendations for overcoming these difficulties.

    Full Text Available This paper focuses on migration in the context of European integration which implies, on the one hand, internal integration, integration within the EU and, on the other hand, the enlargement process related to the countries that have applied to join the EU. The aim is to determine in which way the migration, especially refugee crisis in 2015, had influence on the EU, as a supranational political community, and what was the impact on Serbia which is in the process of integration into the European Union. Migrant crisis has shown that the EU has to confront many different issues including several issues of great importance for its survival and strengthening: how to influence on global processes to a greater extent instead of dealing with the consequences of the global politics of others; how to preserve and keep the values that the EU itself is founded and the values on which should be built upon further construction of the political community and, finally, weather the EU can be transformed in the direction of the United European States, in both the functional and in terms of values, or the EU will move towards deepening of Europe of concentric circles. Faced with extremely complex migration situation, Serbia does not have the appropriate institutional and regulatory framework, nor a political response to a series of complex issues in the area of migration and migration-related issues, such as asylum system, irregular migration, sustainable return of our citizens asylum seekers in EU member states, implementation of the agreement on readmission, the departure of highly educated - brain drain, migration and development, the fight against human trafficking (protection of victims, prevention, criminal prosecution of traffickers, and smuggling of migrants, issues of border management, demarcation and boundary determination (as well as the agreement that should be concluded. Some of these problems migrant crisis has made visible by encouraging coping

    Governments around the world have agreed to end hunger and food insecurity and to improve global nutrition, largely through changes to agriculture and food systems. However, they are faced with a lot of uncertainty when making policy decisions, since any agricultural changes will influence social and biophysical systems, which could yield either positive or negative nutrition outcomes. We outline a holistic probability modeling approach with Bayesian Network (BN) models for nutritional impacts resulting from agricultural development policy. The approach includes the elicitation of expert knowledge for impact model development, including sensitivity analysis and value of information calculations. It aims at a generalizable methodology that can be applied in a wide range of contexts. To showcase this approach, we develop an impact model of Vision 2040, Uganda's development strategy, which, among other objectives, seeks to transform the country's agricultural landscape from traditional systems to large-scale commercial agriculture. Model results suggest that Vision 2040 is likely to have negative outcomes for the rural livelihoods it intends to support; it may have no appreciable influence on household hunger but, by influencing preferences for and access to quality nutritional foods, may increase the prevalence of micronutrient deficiency. The results highlight the trade-offs that must be negotiated when making decisions regarding agriculture for nutrition, and the capacity of BNs to make these trade-offs explicit. The work illustrates the value of BNs for supporting evidence-based agricultural development decisions.

  12. The core determinants of health expenditure in the African context: some econometric evidence for policy.

    2009-06-01

    This paper, using cross-sectional data from 44 (83% of all) African countries for year 2001, presents econometric model estimates linking real per-capita health expenditure (HEXP) to a host of economic and non-economic factors. The empirical results of OLS and robust LAE estimators indicate that real per-capita GDP (PRGDP) and real per-capita foreign aid (FAID) resources are both core and statistically significant correlates of HEXP. Our empirical results suggest that health care in the African context is technically, a necessity rather than a luxury good (for the OECD countries). This suggests that the goal of health system in Africa is primarily 'physiological' or 'curative' rather than 'caring' or 'pampering'. The positive association of HEXP with FAID hints that external resource inflows targeting health could be instrumental for spurring economic progress in good policy environments. Most African countries until the late 1990s experienced economic and political instability, and faced stringent structural adjustment mandates of the major international financial institution lenders for economic development. Therefore, our finding a positive effect of FAID on HEXP could suggest that external resource inflows softened some of the macroeconomic fiscal deficit impacts on HEXP in the 2000s. Policy implications of country-specific elasticity estimates are given.

    Full Text Available This thesis analyzed the feature and different points of the changing of the exchange rate of Korea won against US dollar, then discussed the direction of the completion of Korea exchange rate system. The prediction result of the model GARCH which vividly shows the phenomenon of the auto-regression of the exchange rate has indicated the level of the exchange rate yesterday could explain the circumstance of the change of exchange rate today. Meanwhile, the policy of the US exchange rate will affect the exchange rate of Korea won against US dollar and the volatility of foreign exchange rate. In the present situation of Korean economy in which the liberalization of capital and the independence of the central bank has been established, the choosing range of the exchange system could only be completely changeable exchange rate system or exchange rate system of multilateral arrangement like Europe. However, in terms of the condition of the world economy, the introduction of the latter system is too early. There is an idea that under the changeable exchange rate system which is the only choice, it is the right time to activate the main body of private economy, the financial derivatives market in which the exchange risk could be trade-off. Government should work on and create a policy that would be able to satisfy the expectations of the market participants.

    Overwhelming evidence shows that hazardous work, working conditions, and environment fail to maintain homeostasis results in death or severe disability. Up to the 1980s, governments did not pay major attention to occupational health in developing countries, including India. The Bhopal Gas Tragedy, in 1984, was the turning point in the history of health and safety in India. It was time for the government to think deeply and review the existing legislative measures, for the upliftment of the occupational health situation in India. However, all the services remain grossly underutilized because of inadequate strategies, policies, and the lack of a proper monitoring mechanism, for occupational workers. The present study reviews the fact that Inaction or Destruction of Demands, Use of Power, Appeal to the existing bias of the system, and Exportation and Flexibility of the workers are some of the main reasons for the alarming situation of the Occupational Health Policy (OHP) in India. The existing and traditional condition of the laborers before and after independence is also highlighted in this article. Finally the threats are identified and options are provided to improve the health conditions of the workers.

    The existing literature on forced migration limits our understanding of how violence affects migration to competing destinations. This article adds to the literature on forced migration by studying how armed violence during a period of civil conflict in south-central Nepal influenced the likelihood of local, internal, and international migration. We find that violence has a nonlinear effect on migration, such that low to moderate levels of violence reduce the odds of movement, but when violence reaches high levels, the odds of movement increase. We also find that the effect of violence on mobility increases as the distance of the move increases. When we consider the influence of violence on microlevel decision-making, we find that the effects of individual and household-level determinants were mostly consistent with hypotheses derived from contemporary theories of voluntary migration and that no predictor of migration influenced the decision to migrate differently in the presence of violence.

    Full Text Available According to the analysis of World Bank data on the dynamics of migration indicators in Europe and Fragile State Index data the authors determine the groups of EU countries in geo-economic risk, which forms the pushing factors in the refugee flow formation. The geographic structure of refugees’ migratory flows to the EU is analyzed and the migration corridor dynamics is determined, in particular, it is found out that the overwhelming majority of refugees arrive to the EU through the Central and Eastern Mediterranean channels. In addition, It is determined that strengthening military and political instability in Africa and the Middle East, the tight policies and institutional mechanisms for crossing the EU's borders cause the increased flows of illegal migrants entering the EU in dangerous ways, in particular through the Mediterranean Sea, where a significant number of such persons, especially women and children, die. In addition, EU countries are structured by their migration policies (views on immigration, using of quantitative restrictions on immigration including highly skilled workers. As a result of the legal document study, the authors establish the system of documents identifying the institutional frameworks for the refugees’ and asylum seekers’ migratory flow management.

    For the safety assessment of geological disposal of high-level radioactive waste (HLW), the migration of Eu(III) through compacted bentonite–sand mixtures was measured under expected repository conditions. Under the evaluated conditions, advection and dispersion is the dominant migration mechanism. The role of sorption on the retardation of migration was also evaluated. The hydraulic conductivities of compacted bentonite–sand mixtures were K=2.07×10 −10 –5.23×10 −10 cm/s, The sorption and diffusion of Eu(III) were examined using a flexible wall permeameter for a solute concentration of 2.0×10 −5 mol/l. The effective diffusion coefficients and apparent diffusion coefficients of Eu(III) in compacted bentonite–sand mixtures were in the range of 1.62×10 –12 –4.87×10 –12 m 2 /s, 1.44×10 –14 –9.41×10 –14 m 2 /s, respectively, which has a very important significance to forecast the relationship between migration length of Eu(III) in buffer/backfill material and time and provide a reference for the design of buffer/backfill material for HLW disposal in China. - Highlights: • The migration progress of Eu(III) in compacted bentonite–sand mixtures was researched. • The hydraulic conductivity of cominpacted bentonite–sand mixtures was measured. • The migration length of Eu(III) in buffer/backfill material after a certain period of time was forecasted

    This paper argues that expectations - the process of evaluating the chances for future attainment of valued goals in the home community (stay decision) vs. alternative locations (move decision) - along with family norms about migration are major predictors of intention to move, which in turn is a proximate determinant of migration behaviour. Utilizing longitudinal data from the 1992 and 1994 waves of the Thailand National Migration Survey, logistic regression models show that a strikingly different set of expectations, household demographic indicators, and migrant capital factors were significant determinants of migration intentions for men and women; reflecting Thai gender roles. Migration intentions, in turn, predicted more permanent, but not temporary, survival strategy migration behaviour, while low household income predicted temporary but not more permanent migration behaviour. The measure of perceived family migration norms was a powerful determinant of migration behaviour, but the size of migrant networks was not a statistically significant determinant of either migration intentions or behaviour.

  19. Migration in Asia-Europe Relations

    Juego, Bonn

    2010-01-01

    There is a remarkable difference between viewing migration as a 'social integration' issue, on the one hand, and migration as a 'social relation'. The idea of ‘social integration’ has unrealistic assumptions that see migration as a one-way process, that societies and human relations are static......, and that migrants are mechanical. Policies that are founded on unrealistic assumptions are most likely to generate tensions, conflicts, and contradictions. For a migration process to succeed in forging social harmony and development, it is therefore of decisive and crucial importance to regard migration...... as a ‘social relation’. This is simply because successful migration has to be a harmonious synergy between the migrants (and also the sending countries where they come from) and the receiving society (and its people). As indicated, migrants enter into the receiving society not merely as a passive commodity...

    The author discusses the possibility of determining the proper approach to the study of migration, with a focus on the importance of global, structural, and historical analysis of the phenomenon. A general theoretical outline is presented that tends to show migration as an integral part of the process of social change. The sociological focus on modernization as a theoretical guide influencing the study of migration in Latin America is evaluated. The concept of overpopulation is explained in relation to the migratory process, with reference to capitalist and non-capitalist forms of production.

    Full Text Available Illegal migration is a mobile phenomenon, which ignores national borders, a threat that originates outside the community and extends to Western societies. This phenomenon is becoming larger and irregular migrants are often in a precarious situation and exposed to the criminals involved in various manifestations of organized crime. The future risk factors of the illegal migration are the demographic bomb, because the population is decreasing in European countries and increasing rapidly in poorer countries, droughts, floods, deforestation, that cause conflicts between climate refugees , extreme poverty, totalitarian regimes, epidemics, can trigger millions of people, the elderly and the working population imbalance which leads to the permanent import of immigrants To combat this phenomenon, states must engage and cooperate with each other. Measures taken by states must balance their integration policy for immigrants, legally residents and asylum policy to comply with international conventions. Also, states must adopt anti-immigrant policies, consisting of subordination visa policy to the interests of international security and exchange of information and, not least, to continue the Schengen process, as a value of humanitarian law applied in the field. The aim of the research is to characterize this dangerous phenomenon for the society and the goal is to identify strategies to combat illegal migration.

  2. Determinants of corporate dividend payment policies: A case of the banking industry in South Africa

    Full Text Available Dividends are of strategic importance to organisations because they form the nexus of organisations’ capital structures and have an important bearing on firm value. Consequently, this study sought to investigate factors affecting dividend policy formulations and practices of South African banks by assessing the application of ex ante dividend theory literature on these firms. Our approach followed a mixed-methods design of analysis with a behavioural stand point of eliciting responses from banking experts through a survey. Findings indicate that factors relating to financial performance, investor needs and preferences and regulatory considerations are crucial for dividend decisions among banks. Overall, findings cast doubt on signalling, clientele and catering hypotheses, yet find favourable support for agency and lifecycle theories

    Alekseeva, Nina; Arshinova, Marina; Milanova, Elena

    2017-04-01

    Systems of global environmental rankings have emerged as a result of the escalating need for revealing the trends of ecological development for the world and for certain countries and regions. Both the environmental indicators and indexes and the ratings made on their basis are important for the assessment and forecast of the ecological situation in order to tackle the global and regional problems of sustainable development and help to translate the research findings into policy developments. Data sources for the global environmental ratings are most often the statistical information accumulated in databases of the international organizations (World Bank, World Resources Institute, FAO, WHO, etc.) These data are highly reliable and well-comparable that makes the ratings very objective. There are also good examples of using data of sociological polls, information from social networks, etc. The global environmental ratings are produced by the international organizations (World Bank, World Resources Institute, the UN Environment Program), non-governmental associations (WWF, Climate Action Network Europe (CAN-E), Germanwatch Nord-Süd-Initiative, Friends of the Earth, World Development Movement), research structures (scientific centers of the Yale and Colombian universities, the Oak-Ridge National Laboratory, the New Economic Foundation), and also individual experts, news agencies, etc. Thematic (sectoral) ratings cover various spheres from availability of resources and anthropogenic impact on environment components to nature protection policies and perception of environmental problems. The environmental indicators cover all parameters important for understanding the current ecological situation and the trajectories of its development (the DPSIR model, i.e. drivers, pressures, state, impact and response). Complex (integral) ratings are based on environmental indexes which are combined measurement tools using a complex of aggregated indicators based on a wide range of

    In Morocco, the social and legal framework surrounding sexual and reproductive health has transformed greatly in the past decade, especially with the introduction of the new Family Law or Moudawana. Yet, despite raising the minimum age of marriage for girls and stipulating equal rights in the family, child and forced marriage is widespread. The objective of this research study was to explore perspectives of a broad range of professionals on factors that contribute to the occurrence of child and forced marriage in Morocco. A qualitative approach was used to generate both primary and secondary data for the analysis. Primary data consist of individual semi-structured interviews that were conducted with 22 professionals from various sectors: health, legal, education, NGO's and government. Sources of secondary data include academic papers, government and NGO reports, various legal documents and media reports. Data were analyzed using thematic qualitative analysis. Four major themes arose from the data, indicating that the following elements contribute to child and forced marriage: (1) the legal and social divergence in conceptualizing forced and child marriage; (2) the impact of legislation; (3) the role of education; and (4) the economic factor. Emphasis was especially placed on the new Family Code or Moudawana as having the greatest influence on advancement of women's rights in the sphere of marriage. However, participants pointed out that embedded patriarchal attitudes and behaviours limit its effectiveness. The study provided a comprehensive understanding of the factors that compound the problem of child and forced marriage in Morocco. From the viewpoint of professionals, who are closely involved in tackling the issue, policy measures and the law have the greatest potential to bring child and forced marriage to a halt. However, the implementation of new legal tools is facing barriers and resistance. Additionally, the legal and policy framework should go hand in hand

    Effectiveness of outputs of a qualified intervention can be valued by several positive criteria corresponding to the "quality of life" conception, which is based on the feeling of the health and contentment. The finding that great differences in the income among different social groups in conditions of the liberal market society correlate with several health and social problems brought about to the hypothesis that the decrease of the differences in the income, accompanied by strengthening of various forms of the social cohesion, civic solidarity, legitimate equality, and ethical justice may substantially improve the health status of the population. The hypothesis has been verified in many epidemiological studies and found to be valid enough for the health policy and far-seeing economy. Analytics of the World Bank recommend to governments primary invest into the health of socially week groups in order to decrease their poverty and to keep social conciliation. World Health Organization (WHO) sets in its new program for Europe called "21 Goals for the 21st Century" that differences in the health status among the European states should diminish till 2020 by one third and within the countries by one quarter at least. Both goals should be achieved by a substantial improvement of the health status of the ill-adapted social groups and by significant improvement of those socioeconomical conditions which may have adverse effects namely on the differences in incomes, education and opportunities for employment.

    2005-01-01

    Liquid biofuel support program launched in 1993 in France is implemented through tax exemptions to biofuels produced by agro-industrial chains. Activity levels are fixed by decree and allocated by the government to the different chains. Based on earmarked budget increase voted in parliament, total quantity of biofuels will be increased by 50% in the horizon 2002-2003. A micro-economic biofuel activity model containing a detailed agricultural sector component, that is represented by 700 farms, is used to estimate costs and surpluses generated by the activity at the national level as well as tax exemption levels. Furthermore, Monte Carlo simulation has been used to search for efficient tax exemptions policies in an uncertain environment, where biofuel profitability is significantly affected by petroleum price and soja cake prices. Results suggest that, for the most efficient units both at the industry level (large size biomass conversion units) and at the agricultural sector level (most productive farms), unitary tax exemptions could be decreased by 10-20% for both biofuels, ethyl ether and methyl ester, with no risk for the viability of any existing chain.

    2009-01-01

    China's Strategic Petroleum Reserve (SPR) is currently being prepared. But how large the optimal stockpile size for China should be, what the best acquisition strategies are, how to release the reserve if a disruption occurs, and other related issues still need to be studied in detail. In this paper, we develop a stochastic dynamic programming model based on a total potential cost function of establishing SPRs to evaluate the optimal SPR policy for China. Using this model, empirical results are presented for the optimal size of China's SPR and the best acquisition and drawdown strategies for a few specific cases. The results show that with comprehensive consideration, the optimal SPR size for China is around 320 million barrels. This size is equivalent to about 90 days of net oil import amount in 2006 and should be reached in the year 2017, three years earlier than the national goal, which implies that the need for China to fill the SPR is probably more pressing; the best stockpile release action in a disruption is related to the disruption levels and expected continuation probabilities. The information provided by the results will be useful for decision makers.

    The migration of hydrogen in Lu is determined by electrical resistance measurements in temperature range of 140-170 K. Disordered hydrogen atoms, which are formed by quenching, migrate to order during annealing in the above temperature range. The rate of the resistance decrease depends on the ordering rate of hydrogen. From the resistance decrease during isothermal annealings, the activation energy of hydrogen migration is determined as 0.43 eV (41.5 kJ mol -1 ). (orig.)

    2017-09-01

    Full Text Available The article considers the characteristics of contemporary international migration of population. It has been shown that international migration encompasses all countries over the world and is an important constituent of the globalization of the world-wide economy. Tendencies in the international migration have been described by regions of the world and by type of country. It has been shown that a concentration of international migrants is present in a relatively small number of world countries, while the developed world is more attractive to migrants than the developing countries. The structure of migrants by sex and age has been considered and the most attractive regions for the migration of women and men have been identified. The problems and tendencies of the forced migration of population have been identified. It has been determined that, in many developed countries, the migration inflow of population will increase in importance in the demographic situation. The need to develop a migration policy in the regions of different hierarchical levels and to implement it in practice has been indicated.

    2011-01-01

    In a wide International Context characterised not only by the economical development but also by the social, cultural, political and individual development, we witness more and more to a exchange between the developed and the developing countries, which can be translated especially in the migration of the work force. In theory, all countries are either countries of origin either countries of transit or destination, and they are all responsible for the rights of migrant workers by promoting the rights, by monitoring and by preventing the abusive conditions. The process of migration of the workforce can be divided into three stages: the first coincides with the period prior to departure, the second is represented by the aftermath of the departure and the period of stay in the country of destination, the third stage corresponds to the return in the country of origin. The workers must be protected throughout this process by the international organizations that perform the catalytic role of communication and exchange between countries, for the only purpose of protecting the rights of immigrant and/or immigrants workers. The responsibility for the protection of workers is divided among the various players in the International Labour Organisation. Every country has to apply measures according to the international standards regarding workers' rights, standards that guide the various countries in the formulation and implementation of their policies and legislation. These standards are suggested by International Conventions, the ILO Conventions and other international instruments such as the human rights instrument. There has been a big step forward once the ILO Fundamental Conventions and Conventions on Migrant Workers where implemented and this implementation represented the use of the Guidelines "ILO Multilateral Framework on Labour Migration".

    ENGLISH ABSTRACT: This study was done to assist a local auto carrier company with tactical operational planning. The objective of the planning process is to maximise the number of vehicles delivered while being on time and adhering to staff and maintenance schedule constraints.

    We investigated the feasibility of allowing part of the fleet to roam the closed spatial network, as opposed to the traditional assignment of the complete fleet to fixed routes. We developed decision-making rules for roaming and fixed-to-route auto carriers, and evaluated the quality of these proposed rules, in combination with different fleet compositions, using discrete event simulation and four performance measures.

    We found that the auto carrier company should adopt a tactical operations policy where at least 50% of the fleet is allowed to roam, while roaming auto carriers pick vehicles to transport according to specific rules.

    AFRIKAANSE OPSOMMING: Hierdie studie is gedoen om ’n plaaslike motorvervoer-onderneming te help met taktiese bedryfsbeplanning. Die doelwit van die beplanningsproses is om die aantal voertuie wat betyds afgelewer word te maksimeer met inagneming van personeel- en instandhoudingbeperkings. Ons het die moontlikheid dat ’n deel van die vragmotorvloot swerwend in die geslote ruimtelike roete-network moet opereer, ondersoek. Dit is in teenstelling met die tradisionele vaste toedeling van vragmotors aan roetes. Besluitnemingreëls vir swerwende en vaste-roete vragmotors is ontwikkel, en die gehalte van die reëls is met diskrete simulasie en vier prestasiemaatstawwe evalueer.

    Ons het bevind dat die vervoeronderneming ’n bedryfsbeleid behoort te aanvaar wat toelaat dat ten minste 50% van die vloot swerf, terwyl hierdie swerwende vragmotors voertuie volgens spesifieke reëls by oplaaipunte moet kies.

  3. International migration: a global challenge.

    Martin, P; Widgren, J

    1996-04-01

    Trends in international migration are presented in this multiregional analysis. Seven of the world's wealthiest countries have about 33% of the world's migrant population, but under 16% of the total world population. Population growth in these countries is substantially affected by the migrant population. The migration challenge is external and internal. The external challenge is to balance the need for foreign labor and the commitment to human rights for those migrants seeking economic opportunity and political freedom. The internal challenge is to assure the social adjustment of immigrants and their children and to integrate them into society as citizens and future leaders. Why people cross national borders and how migration flows are likely to evolve over the next decades are explained. This report also presents some ways that countries can manage migration or reduce the pressures which force people to migrate. It is recommended that receiving nations control immigration by accelerating global economic growth and reducing wars and human rights violations. This report examines the impact of immigration on international trade, aid, and direct intervention policies. Although migration is one of the most important international economic issues, it is not coordinated by an international group. The European experience indicates that it is not easy to secure international cooperation on issues that affect national sovereignty. It is suggested that countries desiring control of their borders should remember that most people never cross national borders to live or work in another country, that 50% of the world's migrants move among developing countries, and that countries can shift from being emigration to immigration countries. The author suggests that sustained reductions in migration pressure are a better alternative than the "quick fixes" that may invite the very much feared mass and unpredictable movements.

    This discussion will be limited to the migration of water trapped in the rock salt under the influence of the heat field produced by nuclear waste. This is of concern because hypotheticl scenarios have been advanced in which this fluid movement allows radionuclides to escape to the biosphere. While portions of these scenarios are supported by observation, none of the complete scenarios has been demonstrated. The objectives of the present fluid migration studies are two-fold: 1. determine the character of the trapped fluid in terms of quantity, habitat and chemical constituents; and 2. define the mechanisms that cause the fluid to migrate toward heat sources. Based on the observations to date, fluid migration will not have a major impact on repository integrity. However, the above objectives will be pursued until the impacts, if any, can be quantified

    This paper analyzes internal migration in Mexico over the 1960-70 period. A model of the determinants of migration is specified and estimated for aggregated interstate migration flows. Results show that distance serves as a significant deterrent to migration, that higher destination earning levels are attractive to migrants, and that regions with high unemployment rates experience lower rates of inmigration. An unanticipated finding is that regions with higher earning levels have greater rates of outmigration. The data are disaggregated to examine separate migration relationships for each state. The results are that distance is a lesser deterrent for those migrants with more accessible alternatives, that higher earning levels reduce the deterring effects of distance, and that regions with higher earning levels have lower associated elasticities of migration. It is concluded that economic factors have played a crucial role in internal migration and thus in the changing occupational and geographic structure of the Mexican labor force.

    Neuronal migration is crucial for the construction of the nervous system. To reach their correct destination, migrating neurons choose pathways using physical substrates and chemical cues of either diffusible or non-diffusible nature. Migrating neurons extend a leading and a trailing process. The leading process, which extends in the direction of migration, determines navigation, in particular when a neuron changes its direction of migration. While most neurons simply migrate radially, certain neurons switch their mode of migration between radial and tangential, with the latter allowing migration to destinations far from the neurons’ site of generation. Consequently, neurons with distinct origins are intermingled, which results in intricate neuronal architectures and connectivities and provides an important basis for higher brain function. The trailing process, in contrast, contributes to the late stage of development by turning into the axon, thus contributing to the formation of neuronal circuits. PMID:26755396

    This paper discusses the crucial effects of Turkish health and migration laws on Syrian refugees' access to public health services and social determinants of health. Key aspects of current Turkish laws affect the health of both refugees and Turkish citizens in many ways. The huge influx of refugees is increasing communicable disease risks, overcrowding hospitals, and more generally straining financial and health resources. Turkey's United Nations membership and its candidacy for European Union (EU) have led to increased alignment of Turkey's refugee and migration policies with international law. Major differences remain, however, and Turkey's remaining noncompliance with international refugee laws is a major force driving Syrian refugee's flight to EU countries, as refugees desperately seek the right to better health and social services.

    This paper analyses the determinants of cross-regional variations in expenditure and consumption for non-prescription drugs using the Italian Health Care Service as a case study. This research question has never been posed in other literature contributions. Per capita income, the incidence of elderly people, the presence of distribution points alternative to community pharmacies (para-pharmacies and drug corners in supermarkets), and the disease prevalence were included as possible explanatory variables. A trade-off between consumption of non-prescription and prescription-only drugs was also investigated. Correlation was tested through linear regression models with regional fixed-effects. Demand-driven variables, including the prevalence of the target diseases and income, were found to be more influential than supply-side variables, such as the presence of alternative distribution points. Hence, the consumption of non-prescription drugs appears to respond to needs and is not induced by the supply. The expected trade-off between consumption for prescription-only and non-prescription drugs was not empirically found: increasing the use of non-prescription drugs did not automatically imply savings on prescription-only drugs covered by third payers. Despite some caveats (the short period of time covered by the longitudinal data and some missing monthly data), the regression model revealed a high explanatory power of the variability and a strong predictive ability of future values.

    Full Text Available An optimal business strategy which integrates the decisions, such as pricing, production quantity, and custom er service, in or der to maximize profit is vital for any manufacturing industry. Post sale factors like warranty, spare parts availability, maintenance, service and cost play an important role in the sale of a product. As better warranty signals higher product quality which provides greater assurance to customers, warranty is an important factor in marketing new products. In this paper, a decision model with the price, warranty length and production quantity of a product as decision variables to maximize profit based on the pre-determined product life cycle is presented. The study considers free renewal warranty policy for producers in the static sales market. The expected number of renewals based on the warranty length is derived for lognormally distributed products. The effect of model parameters on the profit is studied.

  14. Determination of migration of phosphorus-based additives from food packaging material into food-simulating solvents by neutron activation/Cerenkov counting

    Samples of food-simulating solvents exposed to food-packaging materials that contain phosphorus-based additives have been examined for migration of phosphorus-containing compounds from the packaging material, using neutron activation/Cerenkov counting. This method has the advantage that commercially produced packaging materials can be used (no elaborate sample preparation as with other radiotracer methods) and no elaborate sample processing techniques are needed to reach the desired levels (low ng/mL) as is usual with most chromatographic or spectroscopic techniques.

  15. Families, children, migration and AIDS.

    Migration is very often a family affair, and often involves children, directly or indirectly. It may give rise to better quality of life for an entire family, or to bitter disappointment, and may also increase vulnerability to HIV and AIDS. This review, carried out for the Joint Learning Initiative on Children and AIDS, links the literature on "migration", on "HIV and AIDS" and on "families". Three themes are sketched: (1) As both HIV prevalence and circular migration increase, former migrant workers affected by AIDS may return to their families for care and support, especially at the end of life, often under crisis conditions. Families thus lose promising members, as well as sources of support. However, very little is known about the children of such migrants. (2) Following patterns of migration established for far different reasons, children may have to relocate to different places, sometimes over long distances, if their AIDS-affected parents can no longer care for them. They face the same adaptation challenges as other children who move, but complicated by loss of parent(s), AIDS stigma, and often poverty. (3) The issue of migrant families living with HIV has been studied to some extent, but mainly in developed countries with a long history of migration, and with little attention paid to the children in such families. Difficulties include involuntary separation from family members, isolation and lack of support, disclosure and planning for children's care should the parent(s) die and differences in treatment access within the same family. Numerous research and policy gaps are defined regarding the three themes, and a call is made for thinking about migration, families and AIDS to go beyond description to include resilience theory, and to go beyond prevention to include care.

    The interest towards "substances of emerging concerns" referred to objects intended to come into contact with food is recently growing. Such substances can be found in traces in simulants and in food products put in contact with plastic materials. In this context, it is important to set up analytical systems characterized by high sensitivity and to improve detection parameters to enhance signals. This work was aimed at optimizing a method based on UHPLC coupled to high resolution mass spectrometry to quantify the most common plastic additives, and able to detect the presence of polymers degradation products and coloring agents migrating from plastic re-usable containers. The optimization of mass spectrometric parameter settings for quantitative analysis of additives has been achieved by a chemometric approach, using a full factorial and d-optimal experimental designs, allowing to evaluate possible interactions between the investigated parameters. Results showed that the optimized method was characterized by improved features in terms of sensitivity respect to existing methods and was successfully applied to the analysis of a complex model food system such as chocolate put in contact with 14 polycarbonate tableware samples. A new procedure for sample pre-treatment was carried out and validated, showing high reliability. Results reported, for the first time, the presence of several molecules migrating to chocolate, in particular belonging to plastic additives, such Cyasorb UV5411, Tinuvin 234, Uvitex OB, and oligomers, whose amount was found to be correlated to age and degree of damage of the containers.

    The SOPHIE Project (acronym for Structural Policies for Health Inequalities Evaluation) has focused on evaluating the impact of structural policies on health equity, considering as such all those policies that exert a powerful influence on the structural determinants of health (e.g., patterns of social stratification, living and working conditions) and thus on health-related exposures through intermediary determinants. In these sections of the International Journal of Health Services, we present some of the main findings of the SOPHIE Project. We include both articles that summarize all the evidence already published in the project on a thematic area (such as labor market, gender, or housing) and articles that present new, unpublished evidence on a specific health inequality or policy. © The Author(s) 2016.

  19. You can lead a horse to water … what Self-Determination Theory can contribute to our understanding of clinical policy implementation.

    2017-01-01

    There has been increasing reliance on policy directives as instruments for shaping clinical practice in health care, despite it being widely recognized that there is a significant translation gap between clinical policy and its implementation. Self-Determination Theory, a widely researched and empirically validated theory of human needs' fulfilment and motivation, offers a potentially valuable theoretical framework for understanding not only why the current policy environment has not led to the anticipated improvement in the quality and safety of clinical care but, importantly, also provides guidance about how organizations can create an environment that can nurture behavioural change in the workforce. We describe an alternative approach to clinical policy-making underpinned by Self-Determination Theory, which we believe has broad application for the science of clinical implementation theory.

    Concerning the human resource management in the health care, Hungarian analysts focus mainly on cross-national migration, which was instigated considerably by joining the European Union in 2004. Contrasted to other health care professionals, dentists emphasized also the importance of in-country migration (mobility) indicating serious dangers of developing inequalities in the dental service. From the point of view of health system planning, the main problem is to balance the needs and the number of professionals in regions and areas with extremely different socio-economic conditions. Under dictatorial governments, this "balancing" (which was experienced also in Hungary) is a forced allocation of young professionals to the target regions. In political freedom and free market economy, these measures are unthinkable. The present domestic area distribution, concerning also the supply through vacancies by old age inactivity and cross-national migration, is ruled by personal decisions of actually graduated and immigrant professionals respectively. Therefore, it is unavoidable to investigate the interrelation of factors (dentists' births place, study migration and decisions for practice allocation) ruling the in-country geographic patterns of dental practices. This evidence-based knowledge can only explain the present situation and provide guidelines for health policy decision makers.

  3. Inter-Provincial Migration Intentions of Family Physicians in Canada: The Roles of Income and Community Characteristics.

    2015-11-01

    The inter-provincial migration patterns of family physicians in canada show that some provinces like newfoundland and saskatchewan experience persistent net out-migration, while others, including ontario and british columbia, are destinations more often than origins of migrants. Governments in provinces exhibiting net out-migration have responded with a number of incentive and recruitment programs. In this study, we investigate the determinants of the stated interprovincial migration intentions of 3,995 rural and urban family physicians in the 2010 wave of the national physician survey. We consider a range of physician characteristics, community attributes and working conditions. We find that in the intention to move, higher compensation has a modest effect, while the community characteristics have a consistently important influence. Our results suggest that policy and program designers should acknowledge the critical role of community-level living and working conditions in their family physician recruitment and retention efforts.

  6. Rural-urban migration and urban unemployment in Nigeria.

    Science.gov (United States)

    Aigbokhan, B E

    1988-01-01

    This paper argues that urban unemployment in Nigeria has been due largely to a failure on the part of the government to pursue policies that reflect commitment on its part to its stated objectives, particularly with regard to employment opportunities. Rural-urban migration has been taking place in the country since the 1960s and at an increasing rate since the 1970s. Economic policies have contributed to this, notably the rural-urban imbalance resulting from the pattern of allocation of public investment expenditures and the wages determination process which tends to concentrate more on the urban sector. These have contributed to the widening urban-rural income differentials. In the face of such migration, the urban industrial sector has been able to absorb only a negligible proportion of migrants. A major factor that has contributed to this is the increased capital-intensity of the sector. Some laudable measures have been introduced this year, notably the establishment of the Directorate of Employment and the Directorate of Food, Road, and Rural infrastructure. The latter, if effectively implemented, should enhance rural income and thereby reduce the rural-urban income gap. The former should reduce the problem of open unemployment. While it is too early to assess the effects of these 2 measures on urban unemployment, they may not improve urban unemployment significantly. There is still the need to design policies to increase labor absorption in general.

  7. Laboratory and in situ determination of the migration processes of actinide complexes and colloids in a fissured granitic environment. El Berrocal project (preliminary activities - phase 0)

    International Nuclear Information System (INIS)

    Astudillo, J.; Del Olmo, C.; Commission of the European Communities, Ispra

    1993-01-01

    The experimental site of El Berrocal has been chosen for a study of the migration of natural radionuclides in a fractured granitic environment. The granite is classified as an alkaline feldspar-rich quartz granite with two micas. The fresh granite is affected by hydrothermal alteration processes related to fractures, which has led to a strong sericitization of albite, and the precipitation of secondary chlorites and carbonates. The most important U-bearing and Th-bearing accessory minerals are uraninite, thorite-auerlite, monazite, anatase, apatite and zircon. Approximately 65% of the total of U in the rock is held as uraninite. In the altered granite, most of the U is held as autunite. Hydrogeochemical data show that Co 2 /H 2 CO 3 is the dominant system, followed by the silica-silicate system. Based on their stability analyses, two zones can be defined: (i) waters north of the dyke and from deep zones where calcite is in equilibrium and albite and gibbsite precipitate, and (ii) surface waters, south of the dyke, subsaturated in relation to calcite, producing the alteration of albite and the precipitation of montmorillonite. The size distribution of the colloids varies, depending on the treatment given to the water samples. The particles are mainly composed of K-feldspars and clay minerals (smectite) and occasionally by quartz, mica, calcite and pollen. The El Berrocal groundwaters have a very low amount of organic matter. Column migration tests have been carried out and were performed with intact granitic cores and with crushed granite. Np proved to be an adequate radionuclide for these experiments. Under oxic conditions and in the absence of organic matter, it was completely retained in both types of columns, whereas in the presence of organic matter a more rapid breakthrough was observed. Under anoxic conditions, and with or without organic matter, Np was found to move faster than under oxic conditions. (author). 13 refs., 46 figs., 23 tabs

  11. Population, migration and urbanization.

    Science.gov (United States)

    1982-06-01

    Despite recent estimates that natural increase is becoming a more important component of urban growth than rural urban transfer (excess of inmigrants over outmigrants), the share of migration in the total population growth has been consistently increasing in both developed and developing countries. From a demographic perspective, the migration process involves 3 elements: an area of origin which the mover leaves and where he or she is considered an outmigrant; the destination or place of inmigration; and the period over which migration is measured. The 2 basic types of migration are internal and international. Internal migration consists of rural to urban migration, urban to urban migration, rural to rural migration, and urban to rural migration. Among these 4 types of migration various patterns or processes are followed. Migration may be direct when the migrant moves directly from the village to the city and stays there permanently. It can be circular migration, meaning that the migrant moves to the city when it is not planting season and returns to the village when he is needed on the farm. In stage migration the migrant makes a series of moves, each to a city closer to the largest or fastest growing city. Temporary migration may be 1 time or cyclical. The most dominant pattern of internal migration is rural urban. The contribution of migration to urbanization is evident. For example, the rapid urbanization and increase in urban growth from 1960-70 in the Republic of Korea can be attributed to net migration. In Asia the largest component of the population movement consists of individuals and groups moving from 1 rural location to another. Recently, because urban centers could no longer absorb the growing number of migrants from other places, there has been increased interest in the urban to rural population redistribution. This reverse migration also has come about due to slower rates of employment growth in the urban centers and improved economic opportunities

    Pillai, P

    1999-04-01

    This paper aims to provide a profile of migration trends in Malaysia since 1970 and to analyze public policy on migration in the context of economic growth and the labor market. The discussion centers on the impact of the Asian financial crisis. There is long history of immigration to Malaysia. The development strategy of the 1970s and 1980s was to create more jobs and restructure employment to meet equity goals. Labor shortages on plantations and construction booms led to a more organized, sustained effort to import labor. Recession in the mid-1980s led to unemployment, but many Malaysians were unwilling to work on plantations, in construction, or in low paying jobs. Economic growth during 1987-96 was very high, and labor shortages spread to service and manufacturing sectors. Migration policy has shifted over the decades. Both the market and the government's promotion of export-based industrialization require access to low cost migrant labor. Public and official recognition of the large number of migrants was not made until 1995. The financial crisis in 1998 led to enforcement of a new migration policy on illegal migrants and greater outflow of migrants. The economic crisis has increased job and income inequities in the region; this encourages continued migration. It is argued that it would be best for Malaysia to maximize short-term gains while minimizing long-term economic, social, and political costs.

    The gut is a continuously renewing organ, with cell proliferation, migration and death occurring rapidly under basal conditions. Since the impact of critical illness on cell movement from crypt base to villus tip is poorly understood, the purpose of this study was to determine how sepsis alters enterocyte migration. Wild type, transgenic and knockout mice were injected with 5-bromo-2'deoxyuridine (BrdU) to label cells in S phase before and after the onset of cecal ligation and puncture and were sacrificed at pre-determined endpoints to determine distance proliferating cells migrated up the crypt-villus unit. Enterocyte migration rate was decreased from 24-96 hours following sepsis. BrdU was not detectable on villi 6 days after sham laparotomy, meaning all cells had migrated the length of the gut and been exfoliated into its lumen. However, BrdU positive cells were detectable on villi 10 days after sepsis. Multiple components of gut integrity altered enterocyte migration. Sepsis decreased crypt proliferation, which further slowed enterocyte transit as mice injected with BrdU after the onset of sepsis (decreased proliferation) had slower migration than mice injected with BrdU prior to the onset of sepsis (normal proliferation). Decreasing intestinal apoptosis via gut-specific overexpression of Bcl-2 prevented sepsis-induced slowing of enterocyte migration. In contrast, worsened intestinal hyperpermeability by genetic deletion of JAM-A increased enterocyte migration. Sepsis therefore significantly slows enterocyte migration, and intestinal proliferation, apoptosis and permeability all affect migration time, which can potentially be targeted both genetically and pharmacologically.

    As the awareness on the global warming diffuses worldwide, the UNFCCC was officially adopted during the 1992 UN Conference on Environment and Development in Rio. Even though Korea is not included in the direct control target countries on emission amount because it is now classified as a developing country, pressures from developed countries to include Korea in the control target countries are mounting as its international standing improves as evidenced in its admission into OECD. The purpose of this study is to review the negotiation policies of developed countries and to analyze the determining factors. The major result of analysis shows that the lower population increase ratio with high population density, lower economic growth ratio, lower growth ratios of metal, machine, and plant industries, and lower relative importance and the growth ratios of coal and petroleum which emit lot of green house gases among energy sources, the more these countries are active in the reinforcement of responsibility and duties of UNFCCC. This proves that these factors are to determine the costs associated with reducing green house gases. In Korea, population growth is high, economic growth ratio is very high, and it has an industrial structure that emits lot of green house gases. The consumption of coal and petroleum is high among energy sources. Therefore, in the process of future negotiation, special features of ultra- dynamic Korean economy which is in contrast to the stable economies of major advanced countries and the tremendous costs associated with reducing green house gases should be stressed. It should be also emphasized that the rules of duty sharing that can be established together with fair, cost-effective, and enduring economic development be devised. 22 refs., 5 figs., 64 tabs.

    Deltas and low-lying coastal regions have long been perceived as vulnerable to global sea-level rise, with the potential for mass displacement of exposed populations. The assumption of mass displacement of populations in deltas requires a comprehensive reassessment in the light of present and future migration in deltas, including the potential role of adaptation to influence these decisions. At present, deltas are subject to multiple drivers of environmental change and often have high population densities as they are accessible and productive ecosystems. Climate change, catchment management, subsidence and land cover change drive environmental change across all deltas. Populations in deltas are also highly mobile, with significant urbanization trends and the growth of large cities and mega-cities within or adjacent to deltas across Asia and Africa. Such migration is driven primarily by economic opportunity, yet environmental change in general, and climate change in particular, are likely to play an increasing direct and indirect role in future migration trends. The policy challenges centre on the role of migration within regional adaptation strategies to climate change; the protection of vulnerable populations; and the future of urban settlements within deltas. This paper reviews current knowledge on migration and adaptation to environmental change to discern specific issues pertinent to delta regions. It develops a new integrated methodology to assess present and future migration in deltas using the Volta delta in Ghana, Mahanadi delta in India and Ganges-Brahmaputra-Meghna delta across India and Bangladesh. The integrated method focuses on: biophysical changes and spatial distribution of vulnerability; demographic changes and migration decision-making using multiple methods and data; macro-economic trends and scenarios in the deltas; and the policies and governance structures that constrain and enable adaptation. The analysis is facilitated by a range of

    The Project Rulison underground nuclear test was a proof-of-concept experiment that was conducted under the Plowshare Program in 1969 in the Williams Fork Formation of the Piceance Basin in west-central Colorado. Today, commercial production of natural gas is possible from low permeability, natural gas bearing formations like that of the Williams Fork Formation using modern hydraulic fracturing techniques. With natural gas exploration and production active in the Project Rulison area, this human health risk assessment was performed in order to add a human health perspective for site stewardship. Tritium (H) is the radionuclide of concern with respect to potential induced migration from the test cavity leading to subsequent exposure during gas-flaring activities. This analysis assumes gas flaring would occur for up to 30 d and produce atmospheric H activity concentrations either as low as 2.2 × 10 Bq m (6 × 10 pCi m) from the minimum detectable activity concentration in produced water or as high as 20.7 Bq m (560 pCi m), which equals the highest atmospheric measurement reported during gas-flaring operations conducted at the time of Project Rulison. The lifetime morbidity (fatal and nonfatal) cancer risks calculated for adults (residents and workers) and children (residents) from inhalation and dermal exposures to such activity concentrations are all below 1 × 10 and considered de minimis. The implications for monitoring production water for conforming health-protective, risk-based action levels also are examined.

  2. Changing patterns of migration in Latin America: how can research develop intelligence for public health?

    Directory of Open Access Journals (Sweden)

    Baltica Cabieses

    Full Text Available Migration patterns in Latin America have changed significantly in recent decades, particularly since the onset of global recession in 2007. These recent economic changes have highlighted and exacerbated the weakness of evidence from Latin America regarding migration-a crucial determinant of health. Migration patterns are constantly evolving in Latin America, but research on migration has not developed at the same speed. This article focuses on the need for better understanding of the living conditions and health of migrant populations in Latin America within the context of the recent global recession. The authors explain how new data on migrant well-being could be obtained through improved evidence from censuses and ongoing research surveys to 1 better inform policy-makers about the needs of migrant populations in Latin America and 2 help determine better ways of reaching undocumented immigrants. Longitudinal studies on immigrants in Latin America are essential for generating a better representation of migrant living conditions and health needs during the initial stages of immigration and over time. To help meet this need, the authors support the promotion of sustainable sources of data and evidence on the complex relationship between migration and health.

    International migration has become an important topic of discussion from a policy and humanitarian perspective. Part of the debate includes a renewed interest in understanding the factors that influence decisions about migration to the US among Mexican youth still residing in their country of origin. The purpose of this study was to advance knowledge specifically about internal and external religiosity and their influence on youths' migration aspirations. The data for this study were collected in 2007 from students enrolled in an alternative high school program located in the state of Guanajuato, Mexico. The findings indicated that as external religiosity increases, the desire to work or live in the USA decreases. Furthermore, as internal religiosity increases, the desire to work or live in the USA and plans to migrate increase. The results are interpreted and discussed in light of previous research on religious and cultural norm adherence.

    Quasidiffusion model accounting the oriented migration is used to describe the observed profiles of 137 Cs distribution in soil. A way of model use in case of real soil, the quasidiffusion migration factor being varied, is suggested. It is shown that in the upper thin soil layer the quasidiffusion migration factor and oriented migration rate values are constant. With further increase of depth the quasidiffusion coefficient grows, the oriented migration rate is unchanged. On the basis of location data characteristic values of migration parameters for different soils of the USSR European territory depending on the soil texture, vegetative cover and moistening are determined

    Full Text Available International migration of population has existed for centuries, as it has activated as a result of globalization. Share the non-economic causes of international migration (causes related to wars, political and religious persecution, the desire to explore new spaces, the desire for family reunification, natural disasters and economic problems (the search for a new job in the absence of the opportunity to find a job in their own country, the search for more paid or creative work, a higher quality of life. Recently, the main reason for migration is economic reasons, on the basis of which the popular migration corridors and the leading directions of migration of labor personnel are identified. Analyzed the main centers of attraction of migration, namely, the United States of America, Federal Republic of Germany and the Russian Federation. Noted that the means and methods of implementation of the State migration policy vary depending on the specific situation on the labor market. So, given the shortage of labor in some European countries, such as Germany, used methods of stimulating immigration. When there is a need to reduce the level of immigration, as in the case of the United States, government regulation sets barriers to a new influx of foreign workers. Revealed, the dynamics of migration primarily due to social phenomena. Adverse external conditions: the deterioration of the economic, environmental or political situation in the country of residence is becoming an important factor in the readiness of potential migrants for forced migration. However, migrants have different socio-economic characteristics, and so they choose the wrong country for migration that they will be closer to social and psychological features.

    3-D seismic imaging of complex geologic structures requires the use of pre-stack imaging techniques, the post-stack ones being unsuitable in that case. Indeed, pre-stack depth migration is a technique which allows to image accurately complex structures provided that we have at our disposal a subsurface velocity model accurate enough. The determination of this velocity model is thus a key element for seismic imaging, and to this end, migration velocity analysis methods have met considerable interest. The SMART method is a specific migration velocity analysis method: the singularity of this method is that it does not rely on any restrictive assumptions on the complexity of the velocity model to determine. The SMART method uses a detour through the pre-stack depth migrated domain for extracting multi-offset kinematic information hardly accessible in the time domain. Once achieved the interpretation of the pre-stack depth migrated seismic data, a kinematic de-migration technique of the interpreted events enables to obtain a consistent kinematic database (i.e. reflection travel-times). Then, the inversion of these travel-times, by means of reflection tomography, allows the determination of an accurate velocity model. To be able to really image geologic structures for which the 3-D feature is predominant, we have studied the implementation of migration velocity analysis in 3-D in the context of the SMART method, and more generally, we have developed techniques allowing to overcome the intrinsic difficulties in the 3-D aspects of seismic imaging. Indeed, although formally the SMART method can be directly applied to the case of 3-D complex structures, the feasibility of its implementation requires to choose well the imaging domain. Once this choice done, it is also necessary to conceive a method allowing, via the associated de-migration, to obtain the reflection travel-times. We first consider the offset domain which constitutes, still today, the strategy most usually used

    We show that, although the amount of mutual entanglement of photons propagating in free space is fixed, the type of correlations between the photons that determine the entanglement can dramatically change during propagation. We show that this amounts to a migration of entanglement in Hilbert space, rather than real space. For the case of spontaneous parametric down-conversion, the migration of entanglement in transverse coordinates takes place from modulus to phase of the biphoton state and back again. We propose an experiment to observe this migration in Hilbert space and to determine the full entanglement

    The glyceride in oil food simulant usually causes serious interferences to target analytes and leads to failure of the normal function of the RP-HPLC column. In this work, a convenient HPLC-UV method for the determination of the total specific migration of nine ultraviolet (UV) absorbers in food simulants was developed based on 1,1,3,3-tetramethylguanidine (TMG) and organic phase anion exchange (OPAE) SPE to efficiently remove glyceride in olive oil simulant. In contrast to the normal ion exchange carried out in an aqueous solution or aqueous phase environment, the OPAE SPE was performed in the organic phase environments, and the time-consuming and challenging extraction of the nine UV absorbers from vegetable oil with aqueous solution could be readily omitted. The method was proved to have good linearity (r≥0.99992), precision (intra-day RSD≤3.3%), and accuracy(91.0%≤recoveries≤107%); furthermore, the lower limit of quantifications (0.05-0.2mg/kg) in five types of food simulants(10% ethanol, 3% acetic acid, 20% ethanol, 50% ethanol and olive oil) was observed. The method was found to be well suited for quantitative determination of the total specific migration of the nine UV absorbers both in aqueous and vegetable oil simulant according to Commission Regulation (EU) No. 10/2011. Migration levels of the nine UV absorbers were determined in 31 plastic samples, and UV-24, UV-531, HHBP and UV-326 were frequently detected, especially in olive oil simulant for UV-326 in PE samples. In addition, the OPAE SPE procedure was also been applied to efficiently enrich or purify seven antioxidants in olive oil simulant. Results indicate that this procedure will have more extensive applications in the enriching or purification of the extremely weak acidic compounds with phenol hydroxyl group that are relatively stable in TMG n-hexane solution and that can be barely extracted from vegetable oil.

  2. Radon depth migration

    Hildebrand, S.T.; Carroll, R.J.

    1993-01-01

    A depth migration method is presented that used Radon-transformed common-source seismograms as input. It is shown that the Radon depth migration method can be extended to spatially varying velocity depth models by using asymptotic ray theory (ART) to construct wavefield continuation operators. These operators downward continue an incident receiver-array plane wave and an assumed point-source wavefield into the subsurface. The migration velocity model is constrain to have longer characteristic wavelengths than the dominant source wavelength such that the ART approximations for the continuation operators are valid. This method is used successfully to migrate two synthetic data examples: (1) a point diffractor, and (2) a dipping layer and syncline interface model. It is shown that the Radon migration method has a computational advantage over the standard Kirchhoff migration method in that fewer rays are computed in a main memory implementation

  3. Internal migration: why do Filipinos move?

    Science.gov (United States)

    Jolipa, N

    1980-01-01

    The rapid movement of Filipinos from 1 part of the Philippines to another is not a new phenomenon, but mobility has been increasing. A study conducted by Peter C. Smith revealed that interprovincial lifetime mobility of the national population increased from 15.8% in 1960 to 17.6% in 1970, while interregional mobility increased from 12.7% to 13.4%. People still disagree as to whether the size and rate of growth of the population are excessive, but there seems to be total consensus as regards its spatial imbalance. Because internal migration appears to be an important factor in national development, a need exists to examine different aspects of internal migration, such as the directions taken by migration flows, the migrants' reasons for moving, the migrants' characteristics, the migrants' success or lack of success at their places of destination, the social problems accompanying internal migration, effforts to deal with the problems caused by internal migration, and the implications of migration trends for policy and for the country's development programs. The most dominant migration trend in the Philippines in recent years has been toward the urban, or more accurately the suburban, areas adjacent to Metropolitan Manila. The city of Manila itself suffered a net outflow, further pointing to the trend toward suburbanization. Migration flows are primarily caused by economic reasons. About one half the sample of a Filipinas Foundation Study moved to provinces other than the province of birth in the pursuit of employment and other economic opportunities. A study of the country's migrant population age 15 and older showed that 53% of migrants were female. For male migrants, age ranges from 20-40; it ranges from 15-35 for females. Where cash income is concerned, migrants in Pernia's study of rural urban migration were better off than nonmigrants. Migrants were, on the average, as well off as native urbanites or metropolitanites. Among the more significant points raised by

    Full Text Available Many digital preservation scenarios are based on the migration strategy, which itself is heavily tool-dependent. For popular, well-defined and often open file formats – e.g., digital images, such as PNG, GIF, JPEG – a wide range of tools exist. Migration workflows become more difficult with proprietary formats, as used by the several text processing applications becoming available in the last two decades. If a certain file format can not be rendered with actual software, emulation of the original environment remains a valid option. For instance, with the original Lotus AmiPro or Word Perfect, it is not a problem to save an object of this type in ASCII text or Rich Text Format. In specific environments, it is even possible to send the file to a virtual printer, thereby producing a PDF as a migration output. Such manual migration tasks typically involve human interaction, which may be feasible for a small number of objects, but not for larger batches of files.We propose a novel approach using a software-operated VNC abstraction layer in order to replace humans with machine interaction. Emulators or virtualization tools equipped with a VNC interface are very well suited for this approach. But screen, keyboard and mouse interaction is just part of the setup. Furthermore, digital objects need to be transferred into the original environment in order to be extracted after processing. Nevertheless, the complexity of the new generation of migration services is quickly rising; a preservation workflow is now comprised not only of the migration tool itself, but of a complete software and virtual hardware stack with recorded workflows linked to every supported migration scenario. Thus the requirements of OAIS management must include proper software archiving, emulator selection, system image and recording handling. The concept of view-paths could help either to automatically determine the proper pre-configured virtual environment or to set up system

      This article is a report of a concept analysis of nurse migration.   International migration is increasing and nurse migrants are active participants in this movement. Migration is a complex term and can be examined from a range of perspectives. Analysis of nurse migration is needed to guide policy, practice and research.   A literature search was undertaken using electronic literature indexes, specific journals and websites, internet search engines and hand searches. No timeframe was placed on the search. Most literature found was published between 2001 and 2009. A sample of 80 documents met the inclusion criteria.   Walker and Avant's approach guided the analysis.   Nurse migration can be defined by five attributes: the motivation and decisions of individuals; external barriers and facilitators; freedom of choice to migrate; freedom to migrate as a human right, and dynamic movement. Antecedents of migration include the political, social, economic, legal, historical and educational forces that comprise the push and pull framework. The consequences of migration are positive or negative depending on the viewpoint and its affect on the individual and other stakeholders such as the source country, destination country, healthcare systems and the nursing profession.   This concept analysis clarified the complexities surrounding nurse migration. A nursing-specific middle-range theory was proposed to guide the understanding and study of nurse migration. © 2011 Blackwell Publishing Ltd.

    Despite reports of high levels of violence among women migrants in Central America, limited evidence exists regarding the health and safety of migrant sex workers in Central America. This study is based on 16 months of field research (November 2012-February 2014), including ethnographic fieldwork, in-depth interviews, and focus groups conducted with 52 internal and international migrant female sex workers in Tecún Umán and Quetzaltenango, Guatemala, key transit and destination communities for both international and internal migrants. The analysis explored migration-related determinants of susceptibility to violence experienced by migrant sex workers across different phases of migration. Violence in home communities and economic considerations were key drivers of migration. Unsafe transit experiences (eg undocumented border crossings) and negative interactions with authorities in destination settings (eg extortion) contributed to migrant sex workers' susceptibility to violence, while enhanced access to information on immigration policies and greater migration and sex work experience were found to enhance agency and resilience. Findings suggest the urgent need for actions that promote migrant sex workers' safety in communities of origin, transit, and destination, and programmes aimed at preventing and addressing human rights violations within the context of migration and sex work.

  11. Political freedom and the response to economic incentives: labor migration in Africa, 1972-1987.

    Barkley, A P; Mcmillan, J

    1994-12-01

    This study examines the thesis that political institutions and the freedoms and civil rights generated by these institutions affect migration decisions. The hypothesis is based on one stated by Adam Smith in 1776, that economic conditions that reflect greater political freedoms and civil liberties harbor higher levels of resource mobility in response to economic incentives. Pooled cross-sectional and time-series analysis is based on data from the World Bank for 32 African countries during 1972-87. Findings support the hypothesis that migration rate is more affected by the expected returns ratio to labor in countries where civil liberties are greater than in nations with fewer civil liberties. The implication, from the inclusion of institutional factors in the model, is that civil liberties have an indirect impact on the rate of labor migration out of agriculture in Africa. The impact is a mix of economic incentives and civil liberties. In the political rights model, the most free countries had the largest migration elasticity. The findings on political rights impacts support findings by Friedman and McMillan that civil liberties are a more important determinant of economic growth than political rights. Further testing for measurement error confirmed that the data were flawed, but not so greatly that the basic findings were overturned. The migration out of African agriculture was found to be sensitive to the effect of price signals, which were conditioned by the degree of political rights and civil liberties. Policy makers are urged to consider both changes in pricing and institutions.

    Full Text Available Abstract Currently, migrants and other mobile individuals, such as migrant workers and asylum seekers, are an expanding global population of growing social, demographic and political importance. Disparities often exist between a migrant population's place of origin and its destination, particularly with relation to health determinants. The effects of those disparities can be observed at both individual and population levels. Migration across health and disease disparities influences the epidemiology of certain diseases globally and in nations receiving migrants. While specific disease-based outcomes may vary between migrant group and location, general epidemiological principles may be applied to any situation where numbers of individuals move between differences in disease prevalence. Traditionally, migration health activities have been designed for national application and lack an integrated international perspective. Present and future health challenges related to migration may be more effectively addressed through collaborative global undertakings. This paper reviews the epidemiological relationships resulting from health disparities bridged by migration and describes the growing role of migration and population mobility in global disease epidemiology. The implications for national and international health policy and program planning are presented.

    Full Text Available The economic, political and social changes experienced globally in recent years have influenced international migration in various countries. The aim of our study is to present the economic and non-economic aspects which determine the quantitative evaluation of migration and to reveal which of the two main factor groups is more dominant. In January 2017, an online questionnaire survey was conducted on the subject of migration. The group of respondents consisted of 438 full-time BSc, MSc and PhD students in Hungarian higher education institutions. Based on these questionnaires, two independent samples t-test, and one-way ANOVA, factor analysis and binary logistic regression procedures were performed. Based on the findings obtained, it was concluded that anti-migration behaviour cannot be explicitly explained by its economic impacts on the labour market. The rejecting attitudes observed on behalf of certain respondents were not in significant correlation with their highest educational levels or their given social class. As a result of the statistical analysis performed, it was concluded that the integration of foreigners is hindered by the so-called socio-cultural barriers, which cannot be removed solely by economic policy measures. Social conflicts of interest have to be eliminated in order for migration to have an active and permanently positive impact on the economy.

  18. Migration: a core public health ethics issue.

    Wild, V; Dawson, A

    2018-05-01

    In this article, we outline the link between migration, public health and ethics. Discussing relevant arguments about migration from the perspective of public health and public health ethics. Critical review of theories and frameworks, case-based analysis and systematic identification and discussion of challenges. Migration is a core issue of public health ethics and must take a case-based approach: seeking to identify the specific ethical dimensions and vulnerabilities in each particular context. Public health as a practice, built upon the core value of justice, requires the protection and promotion of migrants' well-being (even if this produces tension with immigration services). Ethical analysis should take all phases of migration into account: before, during and after transit. We argue that migration policies, at least as they relate to migrants' well-being, should be founded upon a shared humanity, respect for human rights and on the idea that effective public health cannot and should not be confined within the borders and to the citizens of any host country. We make the case for migration to be seen as a core issue of public health ethics. Copyright © 2018 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.

  19. Migration and adaptation to climate change

    Climate change is having an undeniable impact on many human systems and behaviours, including population mobility. This is hardly surprising: migration is an adaptive response to changes in people's circumstances. Yet environmental factors are not the whole story. Socio-economic, political and cultural factors are also closely linked to population movement, and heavily influence vulnerability to both direct and indirect impacts of climate change. Shifts in migration patterns are a strategy of adaptation to complex transformations, and recognising and accommodating this is key in policies for sustainable development and poverty reduction in the context of growing environmental stress.

    Full Text Available Abstract The recent Immigration Bill debate in the United States Congress has again re-ignited the polemic regarding immigration policy. In this essay, I argue that disputes surrounding the legality of migrant workers highlight chronic, underlying problems related to factors that drive migration. The public health field, although concerned primarily with addressing the health needs of migrant populations, cannot remain disengaged from the wider debates about migration. The health needs of migrants, although in themselves important, are merely symptoms of deeper structural process that are intrinsically linked to equity and human rights, and simply focusing on health issues will be insufficient to address these societal pathologies.

  1. Migration processes and self-rated health among marriage migrants in South Korea.

    Research on migrant health mostly examines labor migrants, with some attention paid to the trauma faced by refugees. Marriage migrants represent an understudied vulnerable population in the migration and health literature. Drawing on a Social Determinants of Health (SDH) approach, we use a large Korean national survey and stratified multivariate regressions to examine the link between migration processes and the self-rated health of Korea's three largest ethnic groups of marriage migrants: Korean-Chinese, Vietnamese, and Han Chinese. We find that post-migration socioeconomic status and several social integration factors are associated with the health of marriage migrants of all three groups. Specifically, having more social relationships with Koreans is associated with good health among marriage migrants, while having more social relationships with co-ethnics is associated with worse health. Marriage migrants' perceived social status of their natal and marital families is a better predictor of their health than more objective measures such as their education attainment and that of their Korean husbands. The post-migration social gradients among all ethnic groups demonstrate a dose-response effect of marital family's social standing on marriage migrants' health, independent of their own education and the social standing of their natal families. Lastly, we find some ethnicity-specific predictors such as the association between higher educational level and worse health status among the Vietnamese. This variability by group suggests a more complex set of SDH occurred during the marriage migration processes than a basic SDH framework would predict. Using a new immigrant destination, South Korea, as an example, we conclude that migration and health policies that reduce ethnicity-specific barriers and offer integration programs in early post-migration stages may offer a pathway to good health among marriage migrants.

    The purpose of the present study was to investigate Acid Sensing Ion Channel (ASIC) protein expression and importance in cellular migration. We recently demonstrated that Epithelial Na(+)Channel (ENaC) proteins are required for vascular smooth muscle cell (VSMC) migration; however, the role of the closely related ASIC proteins has not been addressed. We used RT-PCR and immunolabeling to determine expression of ASIC1, ASIC2, ASIC3 and ASIC4 in A10 cells. We used small interference RNA to silence individual ASIC expression and determine the importance of ASIC proteins in wound healing and chemotaxis (PDGF-bb)-initiated migration. We found ASIC1, ASIC2, and ASIC3, but not ASIC4, expression in A10 cells. ASIC1, ASIC2, and ASIC3 siRNA molecules significantly suppressed expression of their respective proteins compared to non-targeting siRNA (RISC) transfected controls by 63%, 44%, and 55%, respectively. Wound healing was inhibited by 10, 20, and 26% compared to RISC controls following suppression of ASIC1, ASIC2, and ASIC3, respectively. Chemotactic migration was inhibited by 30% and 45%, respectively, following suppression of ASIC1 and ASIC3. ASIC2 suppression produced a small, but significant, increase in chemotactic migration (4%). Our data indicate that ASIC expression is required for normal migration and may suggest a novel role for ASIC proteins in cellular migration.

  10. The Globalisation of migration

    Directory of Open Access Journals (Sweden)

    Milan Mesić

    2002-04-01

    Full Text Available The paper demonstrates that contemporary international migration is a constitutive part of the globalisation process. After defining the concepts of globalisation and the globalisation of migration, the author discusses six key themes, linking globalisation and international migration (“global cities”, the scale of migration; diversification of migration flows; globalisation of science and education; international migration and citizenship; emigrant communities and new identities. First, in accordance with Saskia Sassen’s analysis, the author rejects the wide-spread notion that unqualified migrants have lost an (important role in »global cities«, i.e. in the centres of the new (global economy. Namely, the post-modern service sector cannot function without the support of a wide range of auxiliary unqualified workers. Second, a critical comparison with traditional overseas mass migration to the USA at the turn of the 19th and 20th centuries indicates that present international migration is, perhaps, less extensive – however it is important to take into consideration various limitations that previously did not exist, and thus the present migration potential is in really greater. Third, globalisation is more evident in a diversification of the forms of migration: the source area of migrants to the New World and Europe has expanded to include new regions in the world; new immigration areas have arisen (the Middle East, new industrial countries of the Far East, South Europe; intra-regional migration has intensified. Forth, globalisation is linked to an increased migration of experts and the pessimistic notion of a brain drain has been replaced by the optimistic idea of a brain gain. Fifth, contemporary international migration has been associated with a crisis of the national model of citizenship. Sixth, the interlinking of (migrant cultural communities regardless of distance and the physical proximity of cultural centres (the

    A convective-diffusion model has been employed for describing Cs-137 migration in soil. The migration parameters were determined by comparing the calculated vertical distribution profiles with the experimental ones. The migration parameters dependence on the soil state has been studied. Cs-137 penetration rate was found to be function of the soil type, surface state, soil wetness and orography. The obtained values are presented. A method is suggested for revealing the soil surface contamination by Cs-137 produced during NPP operation with distinguishing it from the global contamination background. For this purpose Cs-137 content in the upper 5 mm soil layer is estimated [ru

  12. Public social monitoring reports and their effect on a policy programme aimed at addressing the social determinants of health to improve health equity in New Zealand.

    2014-01-01

    The important role that monitoring plays in advancing global health is well established. However, the role of social monitoring as a tool for addressing social determinants of health (SDH) and health equity-focused policies remains under-researched. This paper assesses the extent and ways in which New Zealand's (NZ) Social Reports (SRs) supported a SDH- and health equity-oriented policy programme nationally over the 2000-2008 period by documenting the SRs' history and assessing its impact on policies across sectors in government and civil society. We conducted key-informant interviews with five senior policy-makers and an e-mail survey with 24 government and civil society representatives on SRs' history and policy impact. We identified common themes across these data and classified them accordingly to assess the intensity of the reports' use and their impact on SDH- and health equity-focused policies. Bibliometric analyses of government publications and media items were undertaken to empirically assess SRs' impact on government and civil society. SRs in NZ arose out of the role played by government as the "benevolent social welfare planner" and an understanding of the necessity of economic and social security for "progress". The SRs were linked to establishing a government-wide programme aimed at reducing inequalities. They have been used moderately to highly in central and local government and in civil society, both within and outside the health sector, but have neither entered public treasury and economic development departments nor the commercial sector. The SRs have not reached the more universal status of economic indicators. However, they have had some success at raising awareness of, and have stimulated isolated action on, SDH. The NZ case suggests that national-level social monitoring provides a valuable tool for raising awareness of SDH across government and civil society. A number of strategies could improve social reports' effectiveness in stimulating

    1982-01-01

    Although there have been many laboratory studies on water movement and contaminant transport, there is a need for more large scale field experiments. Large scale field experiments are necessary to (1) measure hydraulic conductivities on a scale typical of actual shallow land burial facilities and hazardous waste disposal facilities, (2) allow comparisons to be made between full scale and laboratory measurements, (3) verify the applicability of calculational methods for determining unsaturated hydraulic conductivities from water retention curves, and (4) for model validation. Experiments that will provide the information to do this are described in this paper. The results of these experiments will have applications for both the shallow land burial of low level radioactive wastes and the disposal of hazardous chemical wastes. These experiments will provide results that can be used in model verification for system performance. This type of data on experiments done at this scale has not been available, and are necessary for validating unsaturated transport models and other models used to predict long term system performance. Even though these experiments are done on crushed Bandelier Tuff, most models use physical properties of the backfill material such as density, porosity, and water retention curves. For this reason, once the models are validated in these experiments, they can be applied with confidence to other materials as long as the material properties are well characterized. In addition, from known water movement rates, calculable from the results of these experiments, requirements for other parts of the system such as liners, water diversion systems, and system cap requirements can be determined. Lastly, the results of these experiments and their use in model verification will provide a sound scientific basis on which to base decisions on system requirements and system design

The policy of the government of the Philippines is to bring the population growth rate in line with the availability of natural resources and employment opportunities. In its 5-year plan covering 1982-86, the government of the Republic of Korea emphasized social development, attempting to more fully integrate population and development policies and programs within relevant sectors. To reduce its population growth rate to 1.3% by 1992, the government of Thailand is expanding the reach of its family planning program.

  16. Towards an integrated model of international migration

    Douglas S. MASSEY

    2012-12-01

    Full Text Available Demographers have yet to develop a suitable integrated model of international migration and consequently have been very poor at forecasting immigration. This paper outlines the basic elements of an integrated model and surveys recent history to suggest the key challenges to model construction. A comprehensive theory must explain the structural forces that create a supply of people prone to migrate internationally, the structural origins of labour demand in receiving countries, the motivations of those who respond to these forces by choosing to migrate internationally, the growth and structure of transnational networks that arise to support international movement, the behaviour states in response to immigrant flows, and the influence of state actions on the behaviour of migrants. Recent history suggests that a good model needs to respect the salience of markets, recognize the circularity of migrant flows, appreciate the power of feedback effects, and be alert unanticipated consequences of policy actions.

    Dendrochronological dating of buried trees precisely determines the germination year and identifies the stratigraphic context of germination for the trees. This recently developed application of dendrochronology provides accurate time-averaged sedimentation rates of overbank deposition along floodplains and can be used to identify burial events. Previous studies have demonstrated that tamarisk (Tamarix ramosissima) and sandbar willow (Salix exigua) develop anatomical changes within the tree rings (increased vessel size and decreased ring widths) on burial, but observations of plains cottonwood (Populus deltoides ssp. monilifera) are lacking. In September 2016 and June 2017, five buried plains cottonwoods were excavated along a single transect of the interior of a meander bend of the Powder River, Montana. Sediment samples were obtained near each tree for 210Pb and 137Cs dating, which will allow for comparison between dendrochronological and isotopic dating methods. The plains cottonwood samples collected exhibit anatomical changes associated with burial events that are observed in other species. All trees germinated at the boundary between thinly bedded fine sand and mud and coarse sand underlain by sand and gravel, indicating plains cottonwoods germinate on top of point bars prior to overbank deposition. The precise germination age and depth provide elevations and minimum age constraints for the point bar deposits and maximum ages for the overlying sediment, helping constrain past channel positions and overbank deposition rates. Germination years of the excavated trees, estimated from cores taken 1.5 m above ground level, range from 2014 to 1862. Accurate establishment years determined by cross-dating the buried section of the tree can add an additional 10 years to the cored age. The sedimentation rate and accumulation thickness varied with tree age. The germination year, total sediment accumulation, and average sedimentation rate at the five sampled trees is

  18. Structure and behavior as determinants: United States nuclear test ban and chemical and biological arms control policy

    International Nuclear Information System (INIS)

    Reich, J.C.

    1991-01-01

    US efforts to control chemical and biological warfare and nuclear testing are examined with the aim of explaining the paucity of US backed agreements in these areas. Two theoretical perspectives, the behavioral and structural approaches, are used to explore US arms control outcomes. In the behavioral approach, the effects of governmental organization and the bargaining dynamics of policy-making elites with different cognitive styles are posited as important influences on US nuclear test ban and chemical and biological arms control policy outcomes. The behavioral perspective accounts for the timing of all US failed and successful entries (with one exception) into nuclear test bans and chemical and biological warfare restraints. A shortcoming of the behavior approach, however, is that it tends to overemphasize the chances for successful US entry into nuclear test and chemical and biological warfare limitations. Analysis of the same events from the structural perspective helps to correct for expectations generated by behavioral variables for a higher success rate than ultimately resulted. In the structural approach, the focus is on the effect of the organization of international politics on US nuclear test ban and chemical and biological arms control policy outcomes

    2013-01-01

    The evaluation of long-term effects of climate change in cost-benefit analysis has a long tradition in environmental economics. Since the publication of the ''Stern Review'' in 2006, the debate about the impacts of climate change on the economy and how to compare cost and benefits with each other was revived. The assessment of climate change mitigation policies mainly depends on three not mutually exclusive decisions: First, the discount rate chosen, since costs are incurred today and long-term benefits occur in the future. Second, the uncertainties related to the problem of climate change. This debate was spurred by the literature surrounding Martin Weitzman's ''dismal theorem'', stating that the unknown unknowns could be too large for cost-benefit analysis of long-term climate policy measures. And third, the treatment of technological change in economic models of climate policy. This dissertation contributes to all three mentioned aspects and consists of two interrelated parts. First, I discuss norms, economic welfare criteria, and catastrophic risks in the context of climate change. This first part is closely bound to a discussion of the Stern Review. The second part of the dissertation deals with technological change in its various dimensions and addresses several questions: How is technological change taken into consideration in large-scale environment-economy models? How do certain inputs substitute each other? And how does technology affect energy intensity, a key parameter for meeting targets set by climate policy? Alongside these questions, I also discuss how the production of knowledge takes place in an environmental and resource economics framework and how knowledge production patterns have changed during previous decades. While the first part is of theoretical nature, the second part is mainly empirical. Summing up, I suggest approaches towards long-term evaluation of climate policies and how some methodological drawbacks of the ''Stern Review'' could

    Within the framework for the realization of the human right to water and sanitation, States have the obligation to implement programs and public policies that satisfy the basic needs of their population, especially its most vulnerable demographics. In Colombia, this challenge has been addressed through policies that provide a determined essential amount of free water to people whose access to water and sanitation services are limited due to low income. Through a review of legal and technical documents as well as relevant literature, this article presents an analysis of the particular determinants involved in implementing this program in Bogotá and Medellín, as well as some related concerns. Among such factors, we discuss the evolution and changes of the tariff model used in service provision, estimates of basic consumption, the role of social movements and collective action, and user disconnection due to non-payment. The main particularities and differences of each case highlighted the inconveniences related to the method of identifying eligible users and applying assistance to beneficiary user groups, and the need for national guidelines in implementing this policy.

  4. [The regional context of migration: the case of Tabasco].

    Lezama, J L

    1991-09-01

    This work contains reflections on regional influences in determination of migratory processes, as distinct from economic and political influences at the national level. The relationship between migration and region implies discussion of the concept of regions and regional hierarchies in relation to the national level. The economic structure of a region and its influence on migration for example is related to characteristics of the same phenomenon at the national level. Migration to Mexico City and Monterrey represents a process of social change that affects all of Mexican society, both because of the regional diversity and large volume of migrants to the 2 cities and because of their importance in Mexico's economic and social development. Migration at the regional level may be determined by forces within that region or by processes at the national or even international level that are beyond local control. The particular mix of resources available in a region and the level of its development compared to other places within the nation strongly affect migratory potential. The concrete case of petroleum activity in the state of Tabasco is an example of the lack of participation at the regional level in design of investment policy. The petroleum boom of the 1960s in Tabasco produced profound economic changes in the region and caused changes in the local power structure. Particularities in the case of Tabasco included a state economy dominated by petroleum activity, deterioration in the agricultural sector accompanied by increased livestock raising, expansion of zones of population expulsion especially where livestock were most dominant, and consolidation of strong migratory flows toward the petroleum zones. External factors in the regional socioeconomic situation included the impacts generated by petroleum activity, while internal factors included the increasing importance of livestock and eclipse of agriculture even before the petroleum boom.

    Full Text Available Purpose - This paper aims to explore various factors associated with radio frequency identification (RFID adoption with quantitative meta-analysis. More specifically, this paper attempts to measure key variables of RFID adoption derived from Rogers’ innovation theory and further examines how state intervention influences the process of RFID adoption. First, this paper compares, relying on a meta-analysis, various mean effect sizes among technological, organizational and environmental factors (i.e. government-driven policies that Rogers suggested in his innovation model. Design/methodology/approach - In mean effect size analysis, this paper finds that the technological factor is the most powerful factor that affects the RFID adoption. The technological factor is statistically significant across all regions, including North America, Europe and Asia. The organizational factor is significant only in developing countries like Southeast Asian countries and East Asian countries. Environmental factors like government intervention for facilitating RFID adoption are strong enough only in Southeast Asia and Europe. Findings - This paper finds that government’s supportive policy is more effective in Europe but not in America, while external pressure is still more effective in Southeast Asia. These results implicate that developmentalism or government-driven policy can be effective not only in developing countries but also in the case of developed countries. In addition, this paper conducts a seemingly unrelated regression (SUR analysis based on Fisher’s standardized score. Originality/value - In SUR analysis, this paper finds that the correlations between RFID adoption intention and three innovation factors vary across industrial areas. More specifically, the manufacturing area shows negative moderating effect on all three equations where correlations between Rogers’ innovation factors and RFID adoption intention are meta-dependent variables.

    Full Text Available Immigration is one of the most controversial social issues debated nowadays. It is an undeniable fact that the phenomenon is lived in Europe with concern because of its consequences. People who live and coexist in Europe represent a huge cultural variety. Therefore, social and cultural gaps that can affect the basic values of the western societies seem to be inevitable due to the dimensions of the current migration phenomenon. The present studies are based on the European Social Survey Questionnaire (2002, and the Portrait Values Questionnaire (Schwartz, 1992, 2001 and focuses on the relevance of cultural values to explain the acceptance or rejection of the immigrant.. Finally, we emphasize the importance of cultural values -like Harmony or Egalitarianism- for any initiative or social policy which aimes at reducing the problems concerning inmigration in the European context.

  9. Climate Change, Agriculture and Migration: A Survey

    Directory of Open Access Journals (Sweden)

    Chiara Falco

    2018-05-01

    Full Text Available This paper proposes a selective review of the classical economics-based literature on climate change and migration, focusing on the extent to which agriculture might be considered a key mediating channel linking climate change to migration. Overall, climate change is expected to have large and negative effects on the global economy. These effects are even more evident whenever the economic sector considered is the agricultural one, particularly in developing countries. Hence, migration can be viewed as a specific form of adaptation implemented by individuals and households, enabling them to cope, among other things, with weather-induced risk. We show that the importance of agriculture emerges from both plenty of micro-level country studies and relatively few macro-level analyses using cross-sectional data over longer time periods. Thus, policy actions targeted to sustainable agriculture and rural development can both help tackle the challenges posed by climate change and create opportunities in the face of growing migration issues. However, we also stress that much of the current evidence is based on statistical associations that have nothing to do with causal inferences. This calls for the use of a more structural approach and more sophisticated research designs, enabling the researchers to better discriminate among different mechanisms concurrently at work. In addition, further research should be addressed to the role played by food security, a complex dimension largely missing in the current debates on climate change and migration.

    2007-12-01

    To analyze the dynamics of physician international migration patterns and identify the countries deviating most from expected migration rates. A negative binomial log-linear model of physician migration to the United States from every other country was constructed using a panel of country-level data for years 1994-2000. The model was used to identify factors associated with physician migration and to identify countries with higher or lower rates of physician migration than expected. Physician migration varied with a country's GDP per capita in an inverse-U pattern, with highest migration rates from middle-income countries. The absence of medical schools, immigrant networks in the United States, medical instruction in English, proximity to the United States, and the lack of political and civil liberties were also associated with higher migration rates. Countries with higher-than-predicted migration rates included Iceland, Albania, Armenia, Dominica, Lebanon, Syria, the United Arab Emirates, and Bulgaria. Countries with lower-than-predicted migration rates included Mexico, Japan, Brazil, Zimbabwe, Mauritania, Portugal, Senegal, and France. This analysis shows that many of the most powerful factors associated with physician migration are difficult or impossible for countries to change through public policy. GDP per capita and proximity to the U.S. are two of the most powerful predictors of physician migration. Networks of immigrants in the U.S. and fewer political and civil liberties also put countries at higher risk for physician emigration. Several other factors that were associated with physician migration might be more easily amenable to policy intervention. These factors include the absence of a medical school and medical instruction in English. Policies addressing these factors would involve making several difficult tradeoffs, however. Other examples of policies that are effective in minimizing physician migration might be found by examining countries with lower

    Previous evaluation showed insufficient use of a national guideline for integrated local health policy by Regional Health Services (RHS) in the Netherlands. The guideline focuses on five health topics and includes five checklists to support integrated municipal health policies. This study explores the determinants of guideline use by regional Dutch health professionals. A web survey was send to 304 RHS health professionals. The questionnaire was based on a theory- and research-based framework of determinants of public health innovations. Main outcomes were guideline use and completeness of use, defined as the number of health topics and checklists used. Associations between determinants and (completeness of) guideline use were explored by multivariate regression models. The survey was started by 120 professionals (39%). Finally, results from 73 respondents (24%) were eligible for analyses. All 28 Dutch RHS organizations were represented in the final dataset. About half of the respondents (48%) used the guideline. The average score for completeness of use (potential range 1-10) was 2.37 (sd = 1.78; range 1-7). Knowledge, perceived task responsibility and usability were significantly related to guideline use in univariate analyses. Only usability remained significant in the multivariate model on guideline use. Only self-efficacy accounted for significant proportions of variance in completeness of use. The results imply that strategies to improve guideline use by RHSs should primarily target perceived usability. Self-efficacy appeared the primary target for improving completeness of guideline use. Methods for targeting these determinants in RHSs are discussed.

  12. Old Wine in New Bottles? Does Climate Policy Determine Bilateral Development Aid for Renewable Energy and Energy Efficiency?

    Directory of Open Access Journals (Sweden)

    Axel Michaelowa

    2011-05-01

    Full Text Available Published by Palgrave MacmillanSince the UN Conference on Environment and Development in Rio de Janeiro in 1992 bilateral and multilateral donors have stressed that development assistance has increasingly been oriented towards climate-friendly interventions. With respect to energy aid, this should lead to a substantial increase in projects related to renewable energy and energy efficiency. Given a new database of hundreds of thousands of bilateral development assistance projects, we can assess whether such a reorientation has indeed taken place. We find that, contrary to expectations, the share of bilaterally-funded renewable energy and energy efficiency projects did not increase over the period from 1980 to 2008. This share fluctuated greatly, following the price of oil, peaking with the second oil crisis of the early 1980s. The impacts of global climate policy treaties are minor or inexistent. ‘Traditional’ renewable energies such as hydro and geothermal declined, while “new” renewables showed two peaks in the early 1980s and late 1990s. Differences between donor countries are huge. Several countries, including climate sceptics such as the US and Australia, but also the UK and Switzerland, saw a consistent decline. The self-proclaimed climate pioneers such as Germany, the Netherlands, Norway and Sweden show peaks related to both the oil crises and international climate policy. Only in Austria, Denmark, Finland and Spain can ‘new’ climate mitigation development assistance be found.

  14. Mexican experience on migration and development 1990-2013

    Directory of Open Access Journals (Sweden)

    Rodolfo García Zamora

    Full Text Available After 40 years of a long rising emigration from Mexico to the United States, the number of Mexicans increased to 12 million in 2006, while the increased input of remittances reached $26 million dollars in 2007. Yet, the increasing migration and remittances mainly in Zacatecas and Michoacan states do not achieve economic and social development because of the persistent backwardness, unemployment and marginalization. It demands the need for new Policies of Development, Migration and Human Rights that allow exercising the right to not emigrate in a medium term. Positive products of this long migration are the Mexican Migrant Clubs and their Federations that elaborated the concrete development proposals. Whereas, the possibility that these proposals can become a Development, Migration and Human Rights, Comprehensive and Long Term State Policy will depend on the capacity and participation of Mexican Civil Society and the Transnational Communities in both countries.

    Schram, Ashley; Labonté, Ronald; Sanders, David

    2013-01-01

    There are three dominant globalization pathways affecting noncommunicable diseases in Sub-Saharan Africa (SSA): urbanization, trade liberalization, and investment liberalization. Urbanization carries potential health benefits due to improved access to an increased variety of food imports, although for the growing number of urban poor, this has often meant increased reliance on cheap, highly processed food commodities. Reduced barriers to trade have eased the importation of such commodities, while investment liberalization has increased corporate consolidation over global and domestic food chains. Higher profit margins on processed foods have promoted the creation of 'obesogenic' environments, which through progressively integrated global food systems have been increasingly 'exported' to developing nations. This article explores globalization processes, the food environment, and dietary health outcomes in SSA through the use of trend analyses and structural equation modelling. The findings are considered in the context of global barriers and facilitators for healthy public policy. © 2013.

    An important issue in public policy debates is the effect of international migration on welfare in source and host countries. We address this issue by constructing a general equilibrium model of a two-class source or host country. Each country produces many traded and non-traded goods, uses income taxes and distributes the tax receipts equally to all individuals. The analysis examines the effects of permanent migration on class, and national welfare. We show, among other things, that marginal...

  18. Rainfall Patterns and U.S. Migration from Rural Mexico

    Hunter, Lori M.; Murray, Sheena; Riosmena, Fernando

    2014-01-01

    In many rural regions of developing countries, natural resource dependency means changes in climate patterns hold tremendous potential to impact livelihoods. When environmentally-based livelihood options are constrained, migration can become an important adaptive strategy. Using data from the Mexican Migration Project, we model U.S. emigration from rural communities as related to community, household and climate factors. The results suggest that households subjected to recent drought conditions are far more likely to send a U.S. migrant, but only in communities with strong migration histories. In regions lacking such social networks, rainfall deficits actually reduce migration propensities, perhaps reflecting constraints in the ability to engage in migration as a coping strategy. Policy implications emphasize diversification of rural Mexican livelihoods in the face of contemporary climate change. PMID:25473143

    This article examines the experience of a frontier-based community health center when it utilized the Tool for Health and Resilience in Vulnerable Environments (THRIVE) for assessing social determinants of health with a local health consortium. Community members (N = 357) rated safety, jobs, housing, and education among the top health issues. Community leaders integrated these health priorities in a countywide strategic planning process. This example of a frontier county in New Mexico demonstrates the critical role that community health centers play when engaging with local residents to assess community health needs for strategic planning and policy development.

    Full Text Available The movement of rural households from remote uplands to valley floors and to semiurban and urban areas (internal migration is a common phenomenon in the middle mountain districts of Nepal. Understanding the causes and effects of internal migration is critical to the development and implementation of policies that promote land use planning and sustainable resource management. Using geospatial information technologies and social research methods, we investigated the causes and effects of internal migration on land use and land cover patterns in a western mountain district of Nepal between 1998 and 2013. The results show a decreasing number of households at high elevations (above 1400 m, where an increase in forest cover has been observed with a consequent decrease in agricultural land and shrub- or grassland. At lower elevations (below 1400 m, forest cover has remained constant over the last 25 years, and the agricultural land area has increased but has become geometrically complex to meet the diverse needs and living requirements of the growing population. Our findings indicate that internal migration plays an important role in shaping land use and land cover change in the middle mountains of Nepal and largely determines the resource management, utilization, and distribution patterns within a small geographic unit. Therefore, land use planning must take an integrated and interdisciplinary approach rather than considering social, environmental, and demographic information in isolation.

  1. Prestack depth migration

    Two lines form the southern North Sea, with known velocity inhomogeneities in the overburden, have been pre-stack depth migrated. The pre-stack depth migrations are compared with conventional processing, one with severe distortions and one with subtle distortions on the conventionally processed sections. The line with subtle distortions is also compared with post-stack depth migration. The results on both lines were very successful. Both have already influenced drilling decisions, and have caused a modification of structural interpretation in the respective areas. Wells have been drilled on each of the lines, and well tops confirm the results. In fact, conventional processing led to incorrect locations for the wells, both of which were dry holes. The depth migrated sections indicate the incorrect placement, and on one line reveals a much better drilling location. This paper reports that even though processing costs are high for pre-stack depth migration, appropriate use can save millions of dollars in dry-hole expense

    Ohndorf, W

    1989-06-01

    This paper examines the impact of post-1945 migration into Western, Middle, and Northern Europe from Southern Europe, Turkey, and Northern Africa, and migration to the traditional immigration countries by Asian and Latin American immigrants, on the social structures of receiving countries. Between 1955 and 1974, 1) traditional migration to the US and Australia became less important for European countries while traditional receiving countries accepted many immigrants from developing countries; and 2) rapid economic revival in Western and Northern Europe caused a considerable labor shortage which was filled by migrant workers especially from Southern Europe, Turkey, and Northern Africa, who stayed only until they reached their economic goals. Since 1974, job vacancies have declined and unemployment has soared. This employment crisis caused some migrants 1) to return to their countries of origin, 2) to bring the rest of their families to the receiving country, or 3) to lengthen their stay considerably. The number of refugees has also significantly increased since the mid-970s, as has the number of illegal migrants. After the mid-1970s, Europe began to experience integration problems. The different aspects of the impact of migration on social structures include 1) improvement of the housing situation for foreigners, 2) teaching migrants the language of the receiving country, 3) solving the unemployment problem of unskilled migrants, 4) improvement of educational and vocational qualifications of 2nd generation migrants, 5) development of programs to help unemployed wives of migrants to learn the language and meet indigenous women, 6) encouraging migrants to maintain their cultural identity and assisting them with reintegration if they return to their original country, 7) coping with the problems of refugees, and 8) solving the problems of illegal migration. Almost all receiving countries now severely restrict further immigration. [Those policies should result in

  4. Migration and Singapore: implications for the Asia Pacific.

    1994-01-01

    Regarding immigration and emigration issues, there is a need for greater and more detailed data collection, an emphasis on data on illegal as well as legal migration, an examination of the impact of direct foreign investment on job creation and new labor market entrants, and a strengthening of international conventions for protection of foreign workers. The Pacific Economic Cooperation Council (PECC), Human Resource Development Task Force, is the source for projections of labor demand and supply for 18 PECC countries in 1993 and 1994. These projections indicate labor shortages in 1993 in Canada, Taiwan, Hong Kong, Malaysia, Singapore, and Thailand. The greatest labor supplier will be China. Japan and Korea are expected to have economic downturns, which will increase excess labor. The extent of excess labor is estimated to be 8.01 million in 1993 and 12.43 in 1994. The nature of the calculations could potentially exaggerate existing demand. A variety of theories are used to determine the direction and flow of migration, capital, goods and services, and technology. Estimates of migration flows indicate an increase to 100 million migrants in 1992, or 1.8% of world population (35 million in Sub-Saharan Africa, 15 million in Asia and the Middle East, and almost 13 million in Western Europe and North America). The value of remittances is estimated at $66 million (US dollars), which is slightly less than the value of oil trade and exceeds the $46 million in foreign aid. It is hypothesized that wider spatial and income inequalities with expanding globalization will increase migration flows. The case of Singapore illustrates how manipulation of the labor market reduces potential problems. Immigration policy historically encouraged migration of skilled and professional workers. In 1990 foreign workers in Singapore constituted 12% of the labor force. Since 1982 a monthly foreign worker levy has been imposed. The levy is increased when needed in order to slow demand. In 1992

    2009-12-01

    Full Text Available Analysis of the mean date of first captures and median arrival dates of spring migration for 34 species of birds at Eilat, Israel, revealed that the earlier a species migrates through Eilat, the greater is the inter-annual variation in the total time of its passage. Birds arrive during spring migration in Eilat in four structured and independent waves. The annual fluctuation in the initial arrival dates (initial capture dates and median dates (median date of all captures, not including recaptures, did not depend on the length of the migratory route. This implies that migrants crossing the Sahara desert depart from their winter quarters on different Julian days in different years. We suggest that negative correlations between the median date of the spring migration of early and late migrants depends upon the easterly (Hamsin wind period. Moreover, we believe that the phenology of all birds during spring migration in Eilat is possibly also determined by external factors such as weather conditions on the African continent or global climatic processes in the Northern hemisphere. Orphean Warblers (Sylvia hortensis show a strong positive correlation (rs=-0.502 of initial capture date with calendar years, whereas other species such as Barred Warbler (S. nisoria; rs = -0.391 and Spotted Flycatcher (Muscicapa striata; rs = -0.398 display an insignificant trend. The Dead Sea Sparrow (Passer moabiticus and Red-Backed Shrike (Lanius collurio are positively correlated regarding initial arrival date and medians of spring migration.

    International cooperative R and D has been performed within the five years framework of the bilateral agreement between PNC (Power Reactor and Nuclear Fuel Development Corporation) and SCK/CEN (Studiecentrum voor Kernergie/Centre D'etude de L'energie Nucleaire, Mol, Belgium) which is focused on 'The Migration Experiment in argillaceous formation.' This Tertiary argillaceous formation, called Boom clay, is located at about 230m depth in Mol-Dessel area, Belgium. The argillaceous rock is considered to have a high capability for retardation to radionuclides when they migrate in geosphere because of a high content of clay minerals and dissolved carbon-rich pore water. The main purpose of this collaboration work is to characterize the migration phenomena in sedimentary rock through understanding of the behaviour of radionuclides migration in the argillaceous formation. The present report describes the preliminary results of in situ one-dimensional migration experiment with labelled clay core emplaced in borehole under advective condition. In the experiment, radioactive tracer Sr-85 and Eu-152+154 have been used in order to determine the apparent dispersion coefficient and retardation factor of Boom clay. Finally, the following conclusions were obtained by in situ measurement and calculation based on a appropriate migration model; a) From the Sr-85 experiment, diffusive behavior is interpreted to be a dominant phenomena on radionuclides transportation. b) From the Eu-152+154 experiment, very small non-retarded fraction is observed.

    Full Text Available Wheat production in the south of Khuzestan, Iran is constrained by heat stress for late sowing dates. For optimization of yield, sowing at the appropriate time to fit the cultivar maturity length and growing season is critical. Crop models could be used to determine optimum sowing window for a locality. The objectives of this study were to evaluate the Cropping System Model (CSM-CERES-Wheat for its ability to simulate growth, development, grain yield of wheat in the tropical regions of Iran, and to study the impact of different sowing dates on wheat performance. The genetic coefficients of cultivar Chamran were calibrated for the CSM-CERES-Wheat model and crop model performance was evaluated with experimental data. Wheat cultivar Chamran was sown on different dates, ranging from 5 November to 9 January during 5 years of field experiments that were conducted in the Khuzestan province, Iran, under full and deficit irrigation conditions. The model was run for 8 sowing dates starting on 25 October and repeated every 10 days until 5 January using long-term historical weather data from the Ahvaz, Behbehan, Dezful and Izeh locations. The seasonal analysis program of DSSAT was used to determine the optimum sowing window for different locations as well. Evaluation with the experimental data showed that performance of the model was reasonable as indicated by fairly accurate simulation of crop phenology, biomass accumulation and grain yield against measured data. The normalized RMSE were 3%, 2%, 11.8%, and 3.4% for anthesis date, maturity date, grain yield and biomass, respectively. Optimum sowing window was different among locations. It was opened and closed on 5 November and 5 December for Ahvaz; 5 November and 15 December for Behbehan and Dezful;and 1 November and 15 December for Izeh, respectively. CERES-Wheat model could be used as a tool to evaluate the effect of sowing date on wheat performance in Khuzestan conditions. Further model evaluations

    During the 1990s investment in prevention of international or internal migration declined, and crisis intervention increased. The budgets of the UN High Commissioner for Refugees and the UN Development Program remained about the same. The operating assumption is that war, persecution, famine, and environmental and social disintegration are inevitable. Future efforts should be directed to stabilizing populations through investment in sanitation, public health, preventive medicine, land tenure, environmental protection, and literacy. Forces pushing migration are likely to increase in the future. Forces include depletion of natural resources, income disparities, population pressure, and political disruption. The causes of migration are not constant. In the past, migration occurred during conquests, settlement, intermarriage, or religious conversion and was a collective movement. Current migration involves mass movement of individuals and the struggle to survive. There is new pressure to leave poor squatter settlements and the scarcities in land, water, and food. The slave trade between the 1500s and the 1800s linked continents, and only 2-3 million voluntarily crossed national borders. Involuntary migration began in the early 1800s when European feudal systems were in a decline, and people sought freedom. Official refugees, who satisfy the strict 1951 UN definition, increased from 15 million in 1980 to 23 million in 1990 but remained a small proportion of international migrants. Much of the mass movement occurs between developing countries. Migration to developed countries is accompanied by growing intolerance, which is misinformed. China practices a form of "population transfer" in Tibet in order to dilute Tibetan nationalism. Colonization of countries is a new less expensive form of control over territory. Eviction of minorities is another popular strategy in Iraq. Public works projects supported by foreign aid displace millions annually. War and civil conflicts

  14. International migration: The state-sovereignty-migration nexus

    2015-12-01

    Full Text Available Commonly, international human migration is blamed for corroding states sovereignty, especially stemming from policy circles, academic literature and citizens of the host countries. This has attracted the attention of the media highlighting hazards of being a migrant, with some countries viewing migrants as enemies; and, Cuba provides a vivid case. Yet in other countries, migrants are viewed as important contributors to social and economic development, with Mexico, the Dominican Republic and India serving as examples. This article locates migrants in the framework of human rights as guided by international law without prejudice to the demands of state sovereignty, but linking the two in the context of developing international standards. Migration is seen as a feature of human history dating back to primordial time. Nothing appears surprising in the movement of people across borders, defining a migrant through emigration and immigration while giving due respect to the sovereignty of states, both sending and receiving. The article discusses the nexus between migrants and state sovereignty in order to highlight the mutual benefit grounded in international law. It attempts to portray a more positive image of the migrant person in light of the global world, socio-economic development and human rights fundamentals. The main challenge remains that of implementing human rights, which appear to be at the crossroads of individual rights and state sovereignty. The paper reveals how the challenge can be overcome while maintaining the structure of rights and freedoms without infringement on states’ sovereignty. It concludes that migrants remain on the periphery of effective protection from the vagaries of the citizens, partly because the state has a tendency to confine certain rights to its citizenry. States possess discretionary authority to control the ingress of foreign nationals into their territories though sometimes they fail to do that as evidenced

    In this commentary, I argue that beyond a sophisticated supportive architecture to facilitate implementation of actions on the social determinants of health (SDOH) and health inequities, the Health in All Policies (HiAP) project faces two main barriers: lack of awareness within policy networks on the social determinants of population health, and a tendency of health actors to neglect investing in other sectors' complex problems. © 2016 by Kerman University of Medical Sciences.

    The potential link between climate change, migration, and conflict has been widely discussed and is increasingly viewed by policy makers as a security issue. However, considerable uncertainty remains regarding the role that climate variability and change play among the many drivers of migration and conflict. The overall objective of this paper is to explore the potential pathways linking climate change, migration and increased risk of conflict. We review the existing literature surrounding this issue and break the problem into two components: the links between climate change and migration, and those between migration and conflict. We found a large range of views regarding the importance of climate change as a driver for increasing rates of migration and subsequently of conflict. We argue that future research should focus not only on the climate-migration-conflict pathway but also work to understand the other pathways by which climate variability and change might exacerbate conflict. We conclude by proposing five questions to help guide future research on the link between climate change, migration, and conflict. PMID:27110806

    The relationship between climate change and human migration is not homogenous and depends critically on the differential vulnerability of population and places. If places and populations are not vulnerable, or susceptible, to climate change, then the climate–migration relationship may not materialize. The key to understanding and, from a policy perspective, planning for whether and how climate change will impact future migration patterns is therefore knowledge of the link between climate vulnerability and migration. However, beyond specific case studies, little is known about this association in global perspective. We therefore provide a descriptive, country-level portrait of this relationship. We show that the negative association between climate vulnerability and international migration holds only for countries least vulnerable to climate change, which suggests the potential for trapped populations in more vulnerable countries. However, when analyzed separately by life supporting sector (food, water, health, ecosystem services, human habitat, and infrastructure) and vulnerability dimension (exposure, sensitivity, and adaptive capacity), we detect evidence of a relationship among more, but not the most, vulnerable countries. The bilateral (i.e., country-to-country) migration show that, on average, people move from countries of higher vulnerability to lower vulnerability, reducing global risk by 15%. This finding is consistent with the idea that migration is a climate adaptation strategy. Still, ~6% of bilateral migration is maladaptive with respect to climate change, with some movement toward countries with greater climate change vulnerability. PMID:29707262
