abstract in recent years, many researchers have attempted to estimate the soil hydraulic functions (e.g. soil moisture characteristics curve, and hydraulic conductivity function) using particle-size distribution (psd) curve. in these studies, an accurate mathematical representation of psd is required for fitting the observed data. so far, some mathematical models were developed with different l...

BACKGROUND There is paucity of published data on human immunodeficiency virus (HIV) seroprevalence among migrant workers entering Middle-East particularly Kuwait. We took advantage of the routine screening of migrants for HIV infection, upon arrival in Kuwait from the areas with high HIV prevalence, to 1) estimate the HIV seroprevalence among migrant workers entering Kuwait and to 2) ascertain ...

The objective of this study was to analyse mortality in migrants from Finland to Sweden. DESIGN A longitudinal study based on the Finnish Twin Cohort Study. Information about migration from Finland to Sweden, duration of stay in Sweden for the migrants, and deaths 1976-1995 was ...

Stocks and flows of migrant workers from EaP countries in the UK are relatively small, and flows have declined recently following changes to UK immigration policy and the onset of recession. The demographic profile of migrants from EaP countries is similar to that of EUA8 migrants but employment rates have been much lower. A large proportion of migrants to the UK from EaP countries are highly e...

China’s economic and urban developments are driving up the proportion of rural-to-urban migrants in the population. However, because these migrants are often not registered as new residents, national oral health surveys largely miss this group, and especially migrant children. A team of researchers — who included Dr Xiao-li Gao and Professor Colman McGrath from the HKU Faculty of Dentistry — th...

Portuguese Migrants in the German Labor Market: Performance and Self-Selection* Using a large new dataset, we analyze the labor market performance of Portuguese workers in Germany. While previous work compares wages and characteristics of migrants only to those of the natives, we match the data also with an equivalent survey from the sending country. We find that Portuguese migrants as a whole ...

"A survey of residents of and migrants to 15 fast-growing wilderness counties [in the United States] showed that only 25 percent of the migrants increased their income, while almost 50 percent accepted income losses upon their moves to high-amenity counties. Concomitantly, amenities and quality of life were more important factors in the migration decision than was employment, for instance. We...

This study investigates the effects of forced migration on child survival and health in Angola. Using survey data collected in Luanda, Angola, just two years after the end of that country’s prolonged civil war, we compare three groups: migrants who moved primarily due to war, migrants whose moves were not directly related to war, and non-migrants. First, we examine the differences among the thr...

Background: The association between migration and mental health remains unclear. To ensure an adequate health care of migrants, differentiated information on the association between migration and mental disorders is necessary. Method: Cross-sectional study on depression and anxiety symptoms of people migrated to Germany from Turkey, Italy, and Spain as well as ethnic Germans repatriated from th...

This paper explores the productivity differential between return migrants (“Sea Turtles”) and non-migrants through a case study of China’s venture capital (VC) industry. I find that even after correcting for selection bias, return venture capitalists are less productive than comparable non-migrants in targeting promising projects and/or providing value-added services. Given that the VC industry...
