Migration as a human phenomenon has some consequences and repercussions. One of these effects is crime commitment and inducing disturbance in land and national security in immigrants' residence country, in other word, international migration, especially illegal migration, have different penal-security effects. Finding reason that the permeability of borders and increasing illegal traffic, drug ...

Why is there such wide-spread opposition to immigration, although attitudes are generally favorable towards trade? Using concepts from population ethics, this paper shows that impartial observers oppose unskilled immigration if they are inequality-averse, base their decisions on national interest, and have an integrative view of immigration. Moreover, unskilled immigration makes redistribution ...

New tools of genomic analysis shed light on historical puzzles. Migrations of ancient peoples, differences in migration patterns of males and females, historical demography of cultures with ancient roots, and patterns of human genetic diversity are increasingly the focus of integrated analysis by historians, anthropologists, and geneticists.

Given the geography and agroclimatic conditions of the Southeast, coupled with continued population expansion from in-migration, local foods markets may be a promising niche market for some farms in the region. The Southeast has more small farms than any other U.S. region. Using farm-level data, we address the question of how successful southeastern farms engaged in direct sales to consumers di...

A dynamic general equilibrium model is constructed to examine the impact of mass immigration on capital accumulation in life-cycle economies. The model is calibrated to match Canadian demographic characteristics over 1861–1913. This was a period when Canada experienced a dramatic shift in migration patterns, with increasing immigration flows, and a surge in domestic savings and capital inflows....

Constant immigration can stabilize population size fluctuations but its effects on extinction remain unexplored. We show that constant immigration significantly reduced extinction in fruitfly populations with relatively stable or unstable dynamics. In unstable populations with oscillations of amplitude around 1.5 times the mean population size, persistence and constancy were unrelated. Low immi...

Over the past thirty years, crime rates in cities across the United States initially increased and then declined precipitously, in many cases, reaching historic lows. At the same time, the share of the foreign born among the U.S. population has increased rapidly, with the foreign-born Mexican share of the population quadrupling since 1980. The majority of the increase in immigration has taken p...

Immigration to the United States has experienced a phenomenal increase in the last decades. Following the dissolution of the “Iron Curtain” in the late 1980s and early 1990s, Eastern Europeans have been free to emigrate. Since then, there has been an increase in their numbers in the U.S. This study is an analysis of the socio-demographic profile characterizing the immigration from Eastern Europ...

This longitudinal panel study investigated predictors of career adaptability development and its effect on development of sense of power and experience of life satisfaction among 330 Swiss eighth graders. A multivariate measure of career adaptability consisting of career choice readiness, planning, exploration, and confidence was applied. Based on Motivational Systems Theory four groups of pred...
