MEASURING COMPETITION FOR TEXTILES: DOES THE U.S. MAKE THE GRADE?

U.S. textile manufacturing is coming under increasing pressure from foreign competition. This paper evaluates the U.S. competitive position in the yarn segment using established quantifiable measures and provides an overall competitive assessment. The study found the industry in a relatively weak competitive position but that U.S. competitive position is improving.competitiveness, cotton yarn, revealed comparative advantage, tariff equivalent, International Relations/Trade, F29, L67, O57,

Comparative analysis of economic transformation in Poland and selected central European countries

The aim of this study is an empirical evaluation and comparison of Poland’s economic transformation in 1989-2008 against the background of the results achieved in the same period by Hungary, the Czech Republic, the Slovak Republic, Lithuania, and the Ukraine. I have focused on the most distinctive features of economic transformation. The background for the empirical analyses constituted the macroeconomic stabilization frameworks of the economies, the standard growth mechanisms and the conditions of the economies’ competitiveness.convergence, divergence, transformation, competitiveness, transition economies E65, O16, O47, O57, P52

Welfare Costs of Crime and Common Violence: A Critical Review

This paper critically reviews a vast array of literature on the costs of crime and common violence. Using a simple economic model of crime as a theoretical benchmark, we conceptually discuss the estimates available and their potential use as inputs for public policy. We present current methodologies, explore their main results, discuss their limitations, and suggest directions for further research.crime, violence, welfare, costs, contingent valuation, willingness to pay JEL codes: K42, O17, O57

Solar panel thermal cycling testing by solar simulation and infrared radiation methods

For the solar panels of the European Space Agency (ESA) satellites OTS/MAROTS and ECS/MARECS the thermal cycling tests were performed by using solar simulation methods. The performance data of two different solar simulators used and the thermal test results are described. The solar simulation thermal cycling tests for the ECS/MARECS solar panels were carried out with the aid of a rotatable multipanel test rig by which simultaneous testing of three solar panels was possible. As an alternative thermal test method, the capability of an infrared radiation method was studied and infrared simulation tests for the ultralight panel and the INTELSAT 5 solar panels were performed. The setup and the characteristics of the infrared radiation unit using a quartz lamp array of approx. 15 sq and LN2-cooled shutter and the thermal test results are presented. The irradiation uniformity, the solar panel temperature distribution, temperature changing rates for both test methods are compared. Results indicate the infrared simulation is an effective solar panel thermal testing method

Relative mortality improvements as a marker of socio-economic inequality across the developing world, 1990-2009

Using cross country regressions, this paper constructs a novel distance-to-frontier metric for tracking broad socio-onomic inequality (including access of the poor to health infrastructure) over time for individual countries. Given the unavailability of reliable and consistent direct measures of inequality for most poor countries, especially related to non-income aspects of living standards, the metric developed in this paper can be used as an alternative indirect measure that is intuitive and easy to compute. To highlight its potential use, the metric is used to rank countries in terms of improvements in socio-economic inequality for the period since 1990. Notable examples of poor performance are displayed by China, Thailand, Kenya and India. JEL Categories: I14, O57, I32.life expectancy at birth, Preston regression, socio-economic inequality

Period doubling bifurcation and high-order resonances in RR Lyrae hydrodynamical models

We investigated period doubling, a well-known phenomenon in dynamical systems, for the first time in RR Lyrae models. These studies provide theoretical background for the recent discovery of period doubling in some Blazhko RR Lyrae stars with the Kepler space telescope. Since period doubling was observed only in Blazhko-modulated stars so far, the phenomenon can help in the understanding of the modulation as well. Utilising the Florida-Budapest turbulent convective hydrodynamical code, we identified the phenomenon in radiative and convective models as well. A period-doubling cascade was also followed up to an eight-period solution confirming that the destabilisation of the limit cycle is indeed the underlying phenomenon. Floquet stability roots were calculated to investigate the possible causes and occurrences of the phenomenon. A two-dimensional diagnostic diagram was constructed to display the various resonances between the fundamental mode and the different overtones. Combining the two tools, we confirmed that the period-doubling instability is caused by a 9:2 resonance between the 9th overtone and the fundamental mode. Destabilisation of the limit cycle by a resonance of a high-order mode is possible because the overtone is a strange mode. The resonance is found to be sufficiently strong enough to shift the period of overtone with up to 10 percent. Our investigations suggest that a more complex interplay of radial (and presumably non-radial) modes could happen in RR Lyrae stars that might have connections with the Blazhko effect as well.Comment: 9 pages, 9 figures, accepted for publication in MNRA
