determining general and specific combining ability of lines is necessary to use them as parents of hybrid varieties. in addition, estimates of the heritability of characters helps in selecting suitable breeding methods and predicting genetic gains of the traits. to determine general and specific combining abilities and gene effects of agronomic characters, five cms lines and four restorer lines...

Economic and Spatial Determinants of Interregional Migration in Kazakhstan In this paper we analyze economic and spatial determinants of interregional migration in Kazakhstan using quarterly panel data on region to region migration in 2008-2010. In line with traditional economic theory we find that migration is determined by economic factors, first of all income: People are more likely to leave...

The eastern enlargement of the European Union in 2004 triggered a large flow of migrant workers from the new member states to the UK and Ireland. This paper analyzes the impact of this migration wave on the real wages in the source countries. I consider the case of Lithuania, which had the highest share of emigrants relative to its workforce among all ten new member states. Using data from the ...

We examine the correlation between modern human capital and income among adult men in four foraginghorticultural societies of Bolivia. Despite their remote location, we find results similar to those found in developed nations. We find that: (a) education correlates with 4.5% higher overall income and with 5.9% higher wages and math skills correlates with 13.5% higher cash income, and (b) the po...

This study examines how human capital externalities affect audit markets in U.S. cities. A high level of human capital is predicted to improve the quality of labor in all audit firms, but a stronger effect is expected for the more “locally tied” non-Big 4 audit offices. Consistent with this, the quality of audited earnings improves as human capital increases, but the relation is stronger for no...

In the standard Harris–Todaro framework, migration flows arise as disequilibrium driven movements of the population. It is the purpose of this research to modify the simple dualistic model in order to account for the existence of permanent migrants, i.e., of individuals who work in another country without changing their original nationality. Or, in the rural–urban interpretation of the model, o...

The Repunit R49081 = (1049081 − 1)/9 is a probable prime. In order to prove primality R49080 must be approximately 33.3% factored. The status of this factorization is included. Repunits are numbers of the form Rn = (10 − 1)/9. Considerable computer time has been spent factoring repunits, creating interesting primes based on the characteristics of repunits, and searching for repunit primes. One ...

Child Labor and Schooling Response to Changes in Coca Production in Rural Peru Coca eradication and interdiction are the most common policies aimed at reducing the production and distribution of cocaine in the Andes, but little is known about their impact on households. This paper uses the shift in the production of coca leaves from Peru to Colombia in 1995 to analyze the indirect effects of th...

This paper studies how electoral outcomes can shape individuals’ migration decisions. Using the Italian mayoral elections data from 2001 to 2014, I study how foreign citizens’ internal migration with a regular residency permit in North-Italy can be affected by the election of a mayor affiliated to the Northern League (Lega Nord) party, a far-right political movement characterized by a strong fe...

In late September 2012, changes to the Rules and Regulations Pertaining to Immunization, Testing, and Health Screening for Health Care Workers (R23-17-HCW) were proposed to reflect the most current (2011) recommendations of the Center for Disease Control’s (CDC) Advisory Committee on Immunization Practices (ACIP). One of the proposed changes drew many people to a public hearing: the requirement...
