In recent years the genetic algorithm community has shown a growing interest in studying dynamic optimization problems. Several approaches have been devised. The random immigrants and memory schemes are two major ones. The random immigrants scheme addresses dynamic environments by maintaining the population diversity while the memory scheme aims to adapt genetic algorithms quickly to new enviro...

the present study examines the income growth of newly arrived immigrants in Canada using growth curve modeling of longitudinal data. the results from this study indicate that recent immigrants, regardless of visible minority status, face initial earnings disadvantage. However, while immigrants of European origins experience a period of " catch up " early in their Canadian careers, which allows ...

In the U.S. media, unauthorized immigrants are often interchangeably referred to as "illegal aliens," "illegal immigrants," and undocumented immigrants." In spite of formal equivalence, these terms carry different connotations, but the effects of these labels on people's attitudes toward immigrants are not well documented. In this replication study, 274 undergraduate students in psychology resp...

This paper deals with the relative economic performance of immigrants compared to the native born population in Germany. We compare pre-and post-government income, using data from the German SocioEconomic Panel from 1995 to 1997. We categorize six population subgroups by the ethnicity of the adult household members: native-born West Germans, East Germans, " pure " Aussiedler (ethnic German immi...

INTRODUCTION Globally, the number of immigrants is rising every year, so that the number of immigrants worldwide is estimated at 200 million. In Slovenia, immigrants comprise 6.5% of the overall population. Immigrants bring along to a foreign country their cultural differences and these differences can affect immigrants' overall health status and lead to chronic health conditions. The aim of th...

This paper studies the effects of English proficiency on employment of U.S. foreign-born immigrants, using data from the 2001 American Community Survey (ACS). It shows that English proficiency plays an important role in immigrants’ employment and its effects on employment patterns across genders are different. Probit regressions show that immigrants with a higher level of English proficiency ar...

BACKGROUND There is a high and rising rate of immune-mediated diseases in the Western world. Immigrants from South Asia have been reported to be at higher risk upon arrival to the West. We determined the risk of immune-mediated diseases in South Asian and other immigrants to Ontario, Canada, and their Ontario-born children. METHODS Population-based cohorts of patients with asthma, type 1 diab...

OBJECTIVE The prevalence of diabetes mellitus (DM) is increasing rapidly, particularly in Asia. Asian immigrants in Western countries are a fast-growing population who carry both intrinsic risks due to their genetic background and extrinsic risks associated with Western lifestyles. However, recent trends in diabetes prevalence and associated risk factors among Asian immigrants in the USA are no...

Addressing dynamic optimization problems has been a challenging task for the genetic algorithm community. Over the years, several approaches have been developed into genetic algorithms to enhance their performance in dynamic environments. One major approach is to maintain the diversity of the population, e.g., via random immigrants. This paper proposes an elitism-based immigrants scheme for gen...

Background Immigrants from certain low- and middle-income countries are more prone to cancers attributed to viral infections in early life. Cervical cancer is caused by human papillomavirus but is highly preventable by regular screening. We assessed participation among immigrants in a population-based cervical screening programme and identified factors that predicted non-adherence within differ...
