The aim of this paper is to examine immigration and environmental degradation using bibliometric analysis. This paper also analyzes sources of publication, authorship, citations, distributions publications and other bibliometric indicators. The study focuses on a total of 1372 articles published from 2000 to 2020. These articles were collected through an automated process from the Scopus database and later analyzed using techniques such as bibliometric indicators analysis, VOSviewer, and Perish or Publish. The research identified 991 articles from varieties of published sources. The topic of immigrants and environmental degradation has been an emerging topic since 1981. Starting in 2000, most of the scholars actively producing an articles pertinent to this topic. Most of the articles were published in journals, and English is the primary language of research. United States is the leading country in contributing the publications. Meanwhile, the most significant fields in which the sources were produced were environmental science, agricultural and biological sciences, arts and humanities and earth and planetary sciences. However, some limitations has been found. It has been suggested for future research, to lengthen this work to other databases, as well as bibliometric analyses of immigration and environmental degradation in developed and developing countries by adding a new keyword such as energy consumption and climate change. This paper aims to assess recent trends in the expansion of academic literature on immigration and environmental degradation using the bibliometric analysis method. Network visualization and bibliometric indicators are used in this paper to present the results.
Three East Timorese immigrants presented with signs and symptoms of heart failure in early December 1992. One of them also had features of peripheral neuropathy. Another collapsed within 24 hours of admission and attempts at resuscitation failed. The other two showed dramatic response to oral thiamine therapy. An investigation into their dietary history established gross deficiency in fresh vegetables.
For over 2 decades, until the economic crisis in mid-1997, Malaysia's rapid economic growth attracted an influx of foreign labor, mostly from Indonesia, Bangladesh, and the Philippines. In 1997 the number of registered workers was estimated at 1.2 million and undocumented ones at approximately 800,000. The influx created various problems, of which housing is one of the most serious, especially in the Kelang Valley. This paper examines the ways and means by which Indonesian workers, the largest group among foreigners, overcame their accommodation problem. Two types of settlements are identified, that is, illegal ones in the squatter areas and legal ones, which are largely in Malay Reservation Areas. The settlements, which signify Indonesians' success in finding a foothold in Malaysia, today have become a base for more in-migration.
Population ageing and labor out-migration are increasingly challenging normative intergenerational support systems and familial welfare in parts of Asia. Extant studies look at how migration affects the material wellbeing of sending-households, but less is known about how migration shapes the emotional health of non-migrants as origin and destination conditions evolve. This study examines how labor migration among adult children shape the emotional health of elderly parents in Indonesia, and how observed implications are modified by alternative care arrangements and different migrant destinations. Using panel data from 2101 respondents age 50+ in the 2007 and 2014 Indonesia Family Life Survey, and individual-level fixed effects regressions, this study finds that offspring's migration is associated with increased parental depression, net of covariates. Depressive outcomes are abated if resulting care deficits are offset by co-residence or daily interactions with adult children, or if children move to economically lucrative international destinations; however, having a child in Malaysia - a destination characterized by high informal labor employment - increased parental depression. These findings draw attention to the non-economic implications of migration and the distress experienced specifically by parents who lack intergenerational support and who have concerns about child's wellbeing at destination.
Environmental degradation remains a huge obstacle to sustainable development. Research on the factors that promote or degrade the environment has been extensively conducted. However, one important variable that has conspicuously received very limited attention is energy innovations. To address this gap in the literature, this study investigated the effects of energy innovations on environmental quality in the U.S. for the period 1974 to 2016. We have incorporated GDP and immigration as additional regressors. Three indices comprising of CO2 emissions, ecological footprint and carbon footprint were used to proxy environmental degradation. The cointegration tests established long-run relationships between the variables. Using a maximum likelihood approach with a break, the results showed evidence that energy innovations significantly improve environmental quality while GDP degrades the quality of the environment, and immigration has no significant effect on the environment. Policy implications of the results are discussed in the body of the manuscript.
Vitamin D status is highly different in various countries of Europe, the Middle East and Asia. For this review, vitamin D deficiency is defined as serum 25-hydroxyvitamin D (25(OH)D) <25 nmol/l. Within European countries, serum 25(OH)D is <25 nmol/l in 2-30% of adults, increasing in the elderly and institutionalized to more than 80% in some studies. A north-south gradient was observed for serum 25(OH)D in the Euronut and MORE studies with higher levels in Scandinavia and lower levels in Italy and Spain and some Eastern European countries. This points to other determinants than sunshine, e.g. nutrition, food fortification and supplement use. Mean vitamin D intake in Scandinavia is 200-400IU/d, twice that in other European countries. Very low serum 25(OH)D levels have been reported in the Middle East, e.g. Turkey, Lebanon, Jordan and Iran. In these countries serum 25(OH)D was lower in women than in men and associated with clothing habits. In a Lebanese survey, vitamin D deficiency was observed in the majority and occurred mainly in veiled women. In India, vitamin D deficiency was observed in more than 30%, vitamin D status being poor in school children, pregnant women and large cities. Vitamin D status was much better in Malaysia and Singapore, but lower serum 25(OH)D was observed in Japan and China. Rickets and osteomalacia appear quite common in India, but precise data are lacking. Immigrants in Europe from the Middle East and Asia carry a high risk for vitamin D deficiency, pregnant women being especially at risk. Comparison of vitamin D status between countries is hampered by interlaboratory variation of serum 25(OH)D measurement. In addition, there is a need of population-based data. In conclusion, vitamin D deficiency is common in Southern Europe, the Middle East, India, China and Japan. It is less common in Northern Europe and Southeast Asia. Risk groups are young children, the elderly, pregnant women and non-western immigrants in Europe. Important determinants are skin type, sex, clothing, nutrition, food fortification, supplement use, BMI and degree of urbanization.
Migration of health workers 'Brain drain' is defined as the movement of health personnel in search of a better standard of living and life quality, higher salaries, access to advanced technology and more stable political conditions in different places worldwide. The debate about migration of health workers from the developing to the developed world has remained pertinent for decades now. Regardless of the push and pull factors, migration of health care workers from developing countries to developed ones, have done more harm than good on the health care deliveries in the developing countries. This article reviews the literature on the effects of cross-border migration of health care professionals.
