Policies for High-Skilled vs. Low-Skilled Migration inNorth America  [PDF]
Camelia Tigau
Open Journal of Political Science (OJPS) , 2013, DOI: 10.4236/ojps.2013.34022

High-skilled migration has always been given priority and even encouraged by international and national policy. At the same, international agreements for low-skilled migration tend to restrict it. Human capital is considered valuable according to educational levels and working abilities, which puts undocumented migrants in a difficult economic position. The NAFTA area is no exception: while the migration of professionals is given priority by mechanisms like the TN and H1 visas, there is still no agreement to relieve the situation of unskilled immigration across the border from Mexico to the US and Canada in search of a better life. At the same time, migration between Canada and the US is much freer, even though professionals are also given priority; after NAFTA, Canada has even experienced brain drain to the US. The main question is how to reduce unfair differences in policies that prioritize the mobility of certain individuals based on their qualifications. Method: This paper analyzes and compares NAFTA’s impact on policies for high- vs. low-skilled migration. It also uses the author’s ethnographic studies to express the view of migrants on how human capital should be managed internationally.

Nicaraguan Migrants in Costa Rica
Marquette, Catherine M.
Población y Salud en Mesoamérica , 2006,
Abstract: This document is the executive summary of a detailed document entitled, Nicaraguan Migrants and Poverty in Costa Rica, which was prepared for the World Bank in 2006. The more detailed background paper from which this summary is derived was commissioned as a background paper in preparation for an upcoming poverty mission by the World Bank to Costa Rica. This summary and the larger document from which it comes provides: (1) a general overview of the socioeconomic and health situation of Nicaraguan migrants in Costa Rica and (2) a review of the poverty characteristics of these migrants. The primary data sources for the larger paper were successive recent rounds of the Annual National Household Survey in Costa Rica and the 2000 Census. The more detailed report on which this summary is based also reviews issues of data quality, comparability, and methodological problems with respect to existing information on Nicaraguan migrants in Costa Rica. As a summary, the document below, does not include detailed citations, which are of course included in the larger report. Readers are thus, referred to the larger report for citations and more detailed information on the data included in this summary.
International Male Migration and Its Impact on Education of Children and Wives Left Behind: Evidence from Punjab Pakistan  [PDF]
Shahid Iqbal, Riaz Ahmed Mozmi, Faiza Iqbal, Mazhar Saeed
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.26054
Abstract: It is observed that international migration is a growing phenomenon and has got considerable attention. It has profound effects on the source countries. In the present study, an effort has been made to identify the possible impact of migration on families left behind, with special focus on children’s education and females. Migration of labor mobility affects the education of the family members in many ways i.e. remittance enables the migrant families to spend more amount on education, many problems faced by the wives of migrant left behind regarding the education of their children and work load. In-depth interviews were conducted from the respondents for the collection of data. The preliminary findings of the study show that emigration has left deep social-economic impacts on life standards of families left behind in Gujrat.
Myths and Realities about Mexico-United States Migration  [PDF]
Luis Arturo Rivas Tovar, Adela Chávez, Juan Enrique Azuara Munguía, Ana Gabriela Benítez Jurado
iBusiness (IB) , 2014, DOI: 10.4236/ib.2014.62008

This is an article review of state-of-the-art about Mexicans’ migration to the USA, in last 5 years. We analyzed 4 myths: 1). Migration generates negative effects for the receiving country because when migrants arrive. 2). Mexicans’ migration to the USA generates big distortions in the receiving communities and Mexico is the only economic beneficiary. 3). Migrants collapse public health services in USA. 4). Mexican migrants are mistreated by American authorities. The findings will show the lack of empirical evidence of these generalized ideas.

Migration, Employment, and Industrial Development in Japan  [PDF]
Tetsuya Nakajima
Theoretical Economics Letters (TEL) , 2014, DOI: 10.4236/tel.2014.48083
Abstract: Industrial development in Japan is accompanied by massive migration from agricultural to industrial areas. In a modified Harrod-Domar model, this paper compares two steady states, the first and the second, which emerge before and after the termination of such migration, respectively. Then, the paper shows that employment rates must be lower in the second steady state. Further, by examining the effects of fiscal policy, the paper shows that the balanced budget multiplier exceeds unity, and fiscal policy raises households’ disposable income and consumption.

Abstract: In this work, the impulsive force which is the dynamical mechanism that moves the ions inside the stars is obtained.
A Generic Process Migration Algorithm
Amirreza Zarrabi
International Journal of Distributed and Parallel Systems , 2012,
Abstract: Process migration has been advocated as a means of improving multicomputer configuration performance. The optimized migration algorithm utilized in migration event has direct effect on the efficiency and deployment of the process migration system. However, every design has preference factors results in concentration on specific aspect of the migration algorithm. There is no generic migration algorithm which could satisfy all circumstances with almost reasonable costs. This paper reviews the major issues which constitute the developer concerns when implementing a process migration algorithm. This examination indicates the existence of similarity in all process migration algorithms. A new migration algorithm is given and compared to the other algorithms. This algorithm attempts to integrate the significant features of the existing algorithms to form a generic algorithm.
Prestack Depth Migration by a Parallel 3D PSPI  [PDF]
Seonghyung Jang, Taeyoun Kim
International Journal of Geosciences (IJG) , 2016, DOI: 10.4236/ijg.2016.77067
Abstract: Prestack depth migration for seismic reflection data is commonly used tool for imaging complex geological structures such as salt domes, faults, thrust belts, and stratigraphic structures. Phase shift plus interpolation (PSPI) algorithm is a useful tool to directly solve a wave equation and the results have natural properties of the wave equation. Amplitude and phase characteristics, in particular, are better preserved. The PSPI algorithm is widely used in hydrocarbon exploration because of its simplicity, efficiency, and reduced efforts for computation. However, meaningful depth image of 3D subsurface requires parallel computing to handle heavy computing time and great amount of input data. We implemented a parallelized version of 3D PSPI for prestack depth migration using Open-Multi-Processing (Open MP) library. We verified its performance through applications to 3D SEG/EAGE salt model with a small scale Linux cluster. Phase-shift was performed in the vertical and horizontal directions, respectively, and then interpolated at each node. This gave a single image gather according to shot gather. After summation of each single image gather, we got a 3D stacked image in the depth domain. The numerical model example shows good agree- ment with the original geological model.
A Critical Thought about the Theoretical Approaches to Migration Policies and Argentine Experience  [PDF]
Julieta Nicolao
Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.49015
Abstract: This paper presents a critical thought about the design of the most important components of the Argentine migration policies from 2004-2015, together with the main theoretical approaches which emerged from the different disciplines of the social sciences. This paper shows the growing diversity of data and processes related to the definition of migration policies and the need of analyzing the topics from the perspective of International Relations discipline.
