Magnetic moments and electromagnetic radii of nucleon and Δ(1232)\Delta(1232) in an extended GBE model

We derive the exchange currents of pseudoscalar, vector, and scalar mesons from Feynman diagrams, and use them to calculate the magnetic form factors of nucleon and $\Delta(1232)$. The magnetic moments and electromagnetic radii are obtained by using those form factors and the parameters determined from the masses of nucleon and $\Delta(1232)$. We find the magnetic moments and electromagnetic radii of nucleon and $\Delta(1232)$ can be produced very well in the extended Goldstone-boson-exchange model (GBE) in which all of pseudoscalar, vector and scalar meson nonet are included. The magnetic moments of $\Delta(1232)$ are closer to experiment values and results from lattice calculation than the results obtained by the model without other mesons except for pion and sigma.Comment: 15 pages,5 figure

The Emerging Aversion to Inequality: Evidence from Poland 1992-2005

This paper provides an illustration of the changing tolerance for inequality in a context of radical political and economic transformation and rapid economic growth. We focus on the Polish experience of transition and explore self-declared attitudes of the citizens. Using monthly representative surveys of the population, realized by the Polish poll institute (CBOS) from 1992 to 2005, we identify a structural break in the relation between income inequality and subjective evaluation of well-being. The downturn in the tolerance for inequality (1997) coincides with the increasing distrust of political elites.http://deepblue.lib.umich.edu/bitstream/2027.42/64387/1/wp919.pd

Cyclical construction workforce shortage : an evaluation of the current shortage in Western North Carolina

The inadequate supply of skilled construction craft workers is an issue that currently affects the performance of the construction industry. The performance of the construction industry has a significant influence on the growth of the national economy as well as citizens’ wellbeing. The challenges associated with the construction industry’s skilled worker shortage are cyclical. The cyclical nature is a result of the fact that the demand for construction in the U.S. depends on the performance of the overall U.S. economy. The current study evaluates the nature of the current shortage in the western region of North Carolina. Accordingly, the study examines the data collected by the Mountain Area Workforce Development Board, employing a survey that targeted construction firms. The authors have analyzed 46 completed surveys that were collected during the fall of 2018. Among other findings, the study reveals that the demand for laborers and licensed journeymen is higher than other construction positions such as supervisors and estimators. Also, the study shows that entry-level positions such as laborers have higher employee turnover rates compared to more experienced positions. The research could help develop a certified career pathway that provides short-term training and work-based learning opportunities for the raw construction workforce
