In this paper, the problems of "ecological migrants" were analyzed, including the education problem, different life styles, incomplete national protecting measures and policies, with the aim to provide governments with constructive suggestions for the establishment of the education and training system, acceleration of the development of industries (especially the tertiary industry, subsidiary business), and labor transferring, increasing the incomes of "ecological migrants", and making the "ecological migrants" have the financial resources for a long time, thereby better stabilizing the "ecological migrants".展开更多

Methods: This study was conducted using epidemiological surveys and a multi-center randomized controlled clinical trial. A total of 3011 subjects were studied, and the following indices were collected after their return to low altitude areas from the plateau: general health status, blood, urine and stool samples, myo-cardial enzyme levels, liver and kidney function, nerve function, sex hormone levels, microalbuminuria, electrocardiogram (ECG), echocardiography, pulmonary function, and hemorheological markers. These data were compared to those of randomized healthy subjects in the same age range who lived at the same altitude to determine the characteristics of high altitude de-acclimatization syndrome. Based on these characteristics, diagnostic criteria for high altitude de-acclimatization syndrome were formulated. Results: This study demonstrated that the incidence of high altitude de-acclimatization syndrome was 84.36%. Sixty percent of the cases were mild, 30% were medium, and 10% were severe. The incidence was higher among those who returned to a place of lower altitude, resided at a high altitude for a longer period of time, or engaged in heavy labor while at high altitude. Patients with high altitude de-acclimatization syndrome manifested hematological abnormalities and abnormal ventricular function, notably a right ventricular diastolic function, which recovered to baseline function after one to five years. Exposure to long-term hypoxia often caused obvious changes in cardiac morphology, i.e., left and right ventricular hypertrophy, particularly within the right ventricle. In addition, patients with high altitude de-acclimatization syndrome often presented with low blood pressure, low pulse pressure, and microalbuminuria. A few patients presented with occult blood in their feces. The diagnosis of high altitude de-acclimatization syndrome can be made if a patient who recently returns to the plain from the plateau complains of dizziness, weakness, sleepiness, chest tightness, edema, memory loss, and other symptoms and signs that do not alleviate under short-term rehabilitation or symptomatic treatment, and if organic diseases of the heart, lung, kidney, and other organs have been excluded. Conclusion: The diagnosis of high altitude de-acclimatization syndrome should be made after a comprehensive analysis of the patient’s clinical symptoms and signs.展开更多

The ...The Three Gorges Project attracts worldwide attention because of the Three Gorges migrants, and the agriculture of the Three Gorges Reservoir Area is a foundation for the development of the Three Gorges migrants. The Three Gorges Reservoir Area is situated at the mountainous area with bad agricultural development conditions and relatively low levels of development. As a result, the large-scale migration fias special influence on its agricultural development, which has attracted much attention. The paper analyzes influence that the migrants have forced on its agricultural development based on the scientific data, and makes some explorations on the models that are suitable for the development of mountainous agriculture in the Three Gorges Reservoir Area.展开更多

Increasing age leads to health problems, often long-term or chronic, requiring investments in health care. Worse health and dissimilarities in pattern of morbidity/ mortality have been found in foreign-compared to Swedish-born persons, so it is reasonable to assume that this affects use of health care. The exploratory review focuses on elderly migrants’ (>65 years) use of healthcare. The databases Pub Med, EBSCO, CINAHL and ERIC were searched in 2000-2013. A limited number of studies were found;few had a comparative approach, most were from the USA, and focused on migrants from the former Soviet Union or countries in South-East Asia. A range of factors were identified that influence patterns of health care use: language fluency, ability to communicate, self-reported health status, prevalence of chronic disease, physical distance from care provision, availability of transport to reach care, cost of care, the health insurance system, cultural norms and values regarding different forms of care, level of education, and length of residence in the host country. Most studies treated health care from a general perspective and collected data from community and hospital settings, without analysing usage separately. Some studies indicated elderly migrants making use of health care less than other groups but the pattern is not unambiguous: other studies show that there is an overuse of health care. It is therefore difficult to show any particular pattern, or possible differences in use, regarding community versus in-patient care. Studies focusing on migrants’ actual use of health care are few and further research is needed, especially because elderly people form the largest group of users of health care and will be even larger in the future.展开更多

Chronic non-communicable diseases(NCD), and specifically diabetes, are on the front-line, due to the high number of cases at risk, duration and cost of diseases, and availability of effective measures of prevention and treatment. We reviewed the documents of International Agencies on migration and performed a Pub Med search of existing literature, focusing on the differences in the prevalence of diabetes between migrants and native people, the prevalence of NCD in migrants vs rates in the countries of origin, diabetes convergence, risk of diabetes progression and standard of care in migrants. Even in universalistic healthcare systems, differences in socioeconomic status and barriers generated by the present culture of biomedicine make high-risk ethnic minorities under-treated and not protected against inequalities. Underutilization of drugs and primary care services in specific ethnic groups are far from being money-saving, and might produce higher hospitalization rates due to disease progression and complications. Efforts should be made to favor screening and treatment programs, to adapt education programs to specific cultures, and to develop community partnerships.展开更多

This study attempts to fill that gap using survey data from the mountainous areas of Chongqing, Southwest China. From a comparative perspective, this study divided workers into two groups (a young group aged between 16 and 35 years and an old group aged between 36 and 65 years). The average LSCMU values for the young and old groups were 225 days and ~74 days, respectively. Two multi-regression models were used to estimate the determinants of LSCMU in the two groups. The results showed that LSCMU was closely related to individual factors in both groups, including gender, age and job training. Family and community factors, including household size, arable land per capita and the distance from market, had much weaker effects on the dependent variable, especially in the older group. It was noticeable that job training had significant positive effects on LSCMU in both groups; these findings have special implications for the urbanization process in China.展开更多

Results The unmarried migrants had some knowledge of condom. However, their knowledge level and their attitude towards condom use were not so optimistic. Subjects' knowledge of contraceptives and STD/AIDS had a positive influence on their attitude toward condom use. Subjects with positive attitude to condom use were more likely to use condom in sexual activity (OR=1.61). Conclusion Unmarried migrants have lower rate of condom use if they have insufficient knowledge of condom. Therefore, it is essential to strengthen the sexual health education among unmarried sex-active migrants in order to encourage contraceptive use, especially condom use.展开更多

The survey results show that after removal, housing, and infrastructure (electricity, transportation, communication, household appliances) concerning the migrants are improved substantially, but there are still some problems in water drinking, land, employment and income restoration. The later support should put great emphasis on the following aspects: including the rural migrants into the social security system; improving drinking water and irrigation facilities; promoting industrial restructuring; strengthening skills training and education for the migrants, to gradually enrich the migrants and make them live a comfortable life.展开更多

This cross-sectional study has tried to examine HIV/AIDS-related stigma among Nepalese returnee male labor migrants. Migrant workers who have worked at least six months abroad were asked different questions related to sexual behavior, knowledge on HIV/AIDS & condom and HIV/AIDS-related stigma. Stigma was measured on a three-point rating scale as high, average and low stigma. About 58% of migrants had the view “I would rather not know if I have HIV” followed by “I don’t want to be friends with people living with HIV” (53.6% migrants) and “people with HIV are cursed” (35.5% migrants). High stigma was present among 15.5% of the total respondents with high proportion among those with higher age, lower education, rural residence, and no knowledge on Voluntary Counseling and Testing (VCT) service. About a quarter of respondents were of the view that migrants infected with HIV while abroad should not be allowed to return Nepal. Some level of stigma on HIV/AIDS exists among male labor migrants in Nepal. Interventions aiming at reducing stigma should consider the factors like migrants’ age, education, place of residence and knowledge on VCT services.展开更多

This article explores why migrants have a certain level of political trust in their county-level government. Using data of rural-to-urban migrants from the China Family Panel Survey, this study performs a hierarchical linear modeling (HLM) to unpack the multi-level explanatory factors of rural-to-urban migrants’ political trust. Findings show that the individual-level socio-economic characteristics and perceptions of government performance (Level-1), the neighborhood-level characteristics-the physical and social status and environment of neighborhoods (Level-2), and the objective macroeconomic performance of county-level government (Level-3), work together to explain migrants’ trust levels. These results suggest that considering the effects of neighborhood-level factors on rural-to-urban migrants’ political trust merits policy and public management attention in rapidly urbanizing countries.展开更多

It's the source of Yangtze River, Huanghe River and Lancangiiang River. Since the ecological environment became worse in recent decades, Qinghai government conducted an environmental migration project to move the herdsman out of Sanjiangyuan Area to protect the environment. Using the data we collected in five environmental migration resettlement villages in 2009 and the basic information of the nonmigrants, this paper calculated the index of migration differences to examine the selectivity between migrants and nonmigrants. The policy implication will also be discussed in this paper.展开更多

文摘Currently, there is limited literature dealing with the length of stay of circular migrants in urban areas (LSCMU), although many studies have discussed the phenomenon of migration and the determinants of migration. This study attempts to fill that gap using survey data from the mountainous areas of Chongqing, Southwest China. From a comparative perspective, this study divided workers into two groups (a young group aged between 16 and 35 years and an old group aged between 36 and 65 years). The average LSCMU values for the young and old groups were 225 days and ~74 days, respectively. Two multi-regression models were used to estimate the determinants of LSCMU in the two groups. The results showed that LSCMU was closely related to individual factors in both groups, including gender, age and job training. Family and community factors, including household size, arable land per capita and the distance from market, had much weaker effects on the dependent variable, especially in the older group. It was noticeable that job training had significant positive effects on LSCMU in both groups; these findings have special implications for the urbanization process in China.
文摘Objective To understand the perception of potential condom use and its influencing factors so as to promote condom use among unmarried migrantsMethod A survey, using self-administered structured anonymous questionnaire, was conducted among 1 092 unmarried migrants aged 15~24 years old in urban area of Shanghai. Results The unmarried migrants had some knowledge of condom. However, their knowledge level and their attitude towards condom use were not so optimistic. Subjects' knowledge of contraceptives and STD/AIDS had a positive influence on their attitude toward condom use. Subjects with positive attitude to condom use were more likely to use condom in sexual activity (OR=1.61). Conclusion Unmarried migrants have lower rate of condom use if they have insufficient knowledge of condom. Therefore, it is essential to strengthen the sexual health education among unmarried sex-active migrants in order to encourage contraceptive use, especially condom use.

文摘In order to assess the rural migrants' resettlement in the Three Gorges Reservoir Area and provide a reference for formulating the later migrant support policies, we select 342 rural migrants from County A in Hubei Province and County B in Chongqing Municipality for the household survey. The survey results show that after removal, housing, and infrastructure (electricity, transportation, communication, household appliances) concerning the migrants are improved substantially, but there are still some problems in water drinking, land, employment and income restoration. The later support should put great emphasis on the following aspects: including the rural migrants into the social security system; improving drinking water and irrigation facilities; promoting industrial restructuring; strengthening skills training and education for the migrants, to gradually enrich the migrants and make them live a comfortable life.

文摘[Objectives]To analyze and study the reasons for the return of rural migrants in southwest China,so as to come up with effective policy recommendations.[Methods]Based on the questionnaire survey on the return of rural population in Chongqing,Sichuan,Guizhou,and Yunnan,the characteristics and reasons of the return of rural migrants were analyzed.[Results]It was found that the return of rural population in the southwest China was dominated by middle-aged and young people with higher education level,and mainly from Guangdong,Zhejiang,Shanghai,etc.,the time of staying outside gradually declined,and after the return,they were more willing to go outside rural areas to continue to engage in the same or similar work,and they showed stronger willingness to flow again.[Conclusions]The reasons for the return of rural migrants are diversified,mainly affected by limited welfare of medical care,education,and housing resulted from high housing price in employment places,household registration limitation,as well as the need of caring the elderly in the hometown,and returning to start an undertaking.In line with the reasons for return of rural migrants in southwest China,it came up with some effective policy recommendations.
文摘Labor migrants are those of the at-risk groups for HIV. This cross-sectional study has tried to examine HIV/AIDS-related stigma among Nepalese returnee male labor migrants. Migrant workers who have worked at least six months abroad were asked different questions related to sexual behavior, knowledge on HIV/AIDS & condom and HIV/AIDS-related stigma. Stigma was measured on a three-point rating scale as high, average and low stigma. About 58% of migrants had the view “I would rather not know if I have HIV” followed by “I don’t want to be friends with people living with HIV” (53.6% migrants) and “people with HIV are cursed” (35.5% migrants). High stigma was present among 15.5% of the total respondents with high proportion among those with higher age, lower education, rural residence, and no knowledge on Voluntary Counseling and Testing (VCT) service. About a quarter of respondents were of the view that migrants infected with HIV while abroad should not be allowed to return Nepal. Some level of stigma on HIV/AIDS exists among male labor migrants in Nepal. Interventions aiming at reducing stigma should consider the factors like migrants’ age, education, place of residence and knowledge on VCT services.
文摘Massive rural-to-urban migration in China is consequential for political trust: rural-to-urban migrants have been found to hold lower levels of trust in local government than their rural peers who choose to stay in the countryside (mean 4.92 and 6.34 out of 10, respectively, p < 0.001). This article explores why migrants have a certain level of political trust in their county-level government. Using data of rural-to-urban migrants from the China Family Panel Survey, this study performs a hierarchical linear modeling (HLM) to unpack the multi-level explanatory factors of rural-to-urban migrants’ political trust. Findings show that the individual-level socio-economic characteristics and perceptions of government performance (Level-1), the neighborhood-level characteristics-the physical and social status and environment of neighborhoods (Level-2), and the objective macroeconomic performance of county-level government (Level-3), work together to explain migrants’ trust levels. These results suggest that considering the effects of neighborhood-level factors on rural-to-urban migrants’ political trust merits policy and public management attention in rapidly urbanizing countries.
文摘Sanjiangyuan Area is located in Tibetan Plateau in Qinghai Province in China. It's the source of Yangtze River, Huanghe River and Lancangiiang River. Since the ecological environment became worse in recent decades, Qinghai government conducted an environmental migration project to move the herdsman out of Sanjiangyuan Area to protect the environment. Using the data we collected in five environmental migration resettlement villages in 2009 and the basic information of the nonmigrants, this paper calculated the index of migration differences to examine the selectivity between migrants and nonmigrants. The policy implication will also be discussed in this paper.

文摘The massive scale of new-generation rural-urban migrants in China has attracted extensive scholarly attention in recent years.While previous studies on China’s rural migrant workers focus on migrants’settlement intentions,migrants’family migration decision-making and the intergenerational differences between the old-generation migrants and new-generation migrants are underexplored.Based on the data of the 2017 China Migrants Dynamic Survey,this paper adopts a multilevel logistic regression approach to explore family and destination factors influencing the family migration decisions of China’s new generation of rural migrant workers.The empirical results reveal that both the migrants’family and destination attributes significantly influence their family migration decision.The demographic and socioeconomic characteristics of the family have been pivotal factors underlying the family migration decision of China’s new generation rural-urban migrants,while 16.9%of the chances are explained by between-destination differences.Self-employed migrants with housing properties in host cities,long migration duration and high-income levels are more likely to migrate with their family members.Yet,the possibility of family migration is found to be significantly and negatively correlated with the age,education level,number of children and inter-provincial mobility of the new generation of migrant workers.In addition,new-generation rural-urban migrants’family migration is more likely to be found in cities with service-oriented industry structures,better environmental quality,and higher hukou barriers which is possibly related to more job opportunities.These research findings not only complement the existing literature on China’s new generation of rural urban migrants,but also have important policy implications for reforming the hukou system and enhancing social integration of the rural-to-urban migrant population.

文摘The inner-urban residential location choice is a topic of continuing interest in urban geography.However,not much research has been done on migrants’rental location choices.Based on data from a questionnaire completed by 276 migrant renters in Guangzhou,this paper analyzes the demographics and social class characteristics of migrants,and the condition and location of housing preferred by this population.The results show that the migrants in Guangzhou mainly rent in the Center Business District(CBD)area(Tianhe District)and Huangpu,Panyu and Haizhu districts.The main reason for this choice of location choices is the houses’convenience to their workplaces.A second reason is that nearby subways make travel convenient,for consumption and daily life,for children to go to school,and for access to large shopping centers/malls.

文摘Background:The household registration system in China places migrants in a vulnerable status regarding access to local public services,including limited access to health services.Most studies on migrants’health services utilization targeted on working-age migrants,and there has been a paucity of studies conducted among elderly migrants.This study aims to investigate the status of health services utilization and its influential factors among elderly migrants.Methods:Data(13,043 participants,52.4%male,mean age 66.22±6.20)were derived from the 2015 Migrant Dynamics Monitoring Survey.The outcome variable in the study was health services utilization,consisting of doctor visits,hospitalization and local inpatient care.The Behavioral Model of Health Service Use was applied to categorize the influential factors into three components,including predisposing,enabling and need factors.Multivariate logistic regression analysis was used to investigate the influential factors of the three components of health services utilization.Results:Of the total sample,45.5%would visit a doctor when they were ill,81.8%would prefer to be hospitalized when recommended by doctors,and 71.6%(those who were hospitalized)would choose to receive local inpatient care rather than going back to their hometown.Age,marital status,household income,years of residence,migration range,reasons for migration,size of friend network,health insurance type,local health insurance status and chronic disease status were significantly associated with health services utilization.Conclusion:A low level of local health services utilization was observed among elderly migrants.Enabling factors played important roles in promoting health services utilization among elderly migrants.Policy and decision makers may consider improving the capability for elderly migrants to access health services,such as increasing income and providing local health insurance.
文摘Street vending is a form of informal economy.The main participants of street vending economy consist of exploited workers,rural-urban migrants who are in low level of socioeconomic households,common workers,and some individual households.Most of the studies and articles have explored how to regulate the street vending economy and how to facilitate the relationship between vendors and city authorities,but the important constitute of street vending economies,rural migrants,has received little attention from scholars and there is little research about it.What role does street vending economy play in the lives of this segment of this population which itself faces a number of challenges in migrating and integrating into the city?We have found out that street vending functions as a platform which helps these people to better integrate into the cities.Through desktop research and case studies,this paper explores how street vending economy helps rural to urban migrants integrate into the city from four perspectives:identity integration,integrating in economic level,integrating in social level,and females'empowerment.
文摘Head waiter Liu Hui used to think he would never become a labourer like his neighbour, until recently when the medium-sizedrestaurant in Beijing where Liu works established a union branch and began signing labour contracts with its employees.When he was a school boy in the early 1980s, Liu dreamed of becoming a labourer once he’d grown up.
