This paper uses micro data from the German Socio-Economic Panel to document that the wage structure in West Germany was remarkably stable over the period 1984–97, with little variation over time in wage or earnings inequality among and within different skill groups. The paper investigates a number of possible explanations for the stability of the wage structure and concludes that it is attribut...

This paper presents investigation effects of a sharp edged gust on aeroelastic behavior and time-domain response of a typical section model using Jones approximate aerodynamics for pure plunging motion. Flutter analysis has been done by using p and p-k methods developed for presented finite-state aerodynamic model for a typical section model (airfoil). Introduction of gust analysis as a linear ...

OBJECTIVE To detect and explain changing trends in incidence, case fatality rates, and mortality for unintentional injuries in the Netherlands for the years 1950 through 1995. METHODS Using national registry data, the authors analyzed trends in traffic injuries, occupational injuries, and home and leisure injuries. RESULTS Between 1950 and 1970, mortality from unintentional injuries rose, r...

The relationship of the clavigerite genera Diartiger Sharp and Microdiartiger Sawada is discussed, and the synonymy of the two genera proposed by Besuchet (1986) is followed. This results in two new combinations: D. thinhi (Nomura), comb. n. and D. songxiaobini (Yin & Li), comb. n. Two new species, D. dentatus Yin & Li, sp. n. and D. yaoluopingensis Yin & Li, sp. n. are described from Anhui, Ea...

The effects of sodium bicarbonate concentration, population density, and temperature on the maintenance of an outdoor monoculture of the cyanobacterium Spirulina platensis were studied. A clear response by Spirulina to the concentration of bicarbonate was evident, with 0.2M bicarbonate representing the lowest concentration in which a monoculture could be maintained. When the temperatures fell d...

Four new species of the genus Thoracophorus Motschulsky, 1857 of the Neotropical region are described: T. verhaaghi n. sp., T. zicsii n. sp., T. struyvei n. sp., and T. perplexus n. sp. The new species originate from French Guiana, Peru, and Ecuador. Similar species T. filum Sharp, 1887, T. proximus Irmler, 1985, T. exilis (Erichson, 1840) and T. aequalis Sharp, 1887 are compared to discuss dif...

Recently, BMI screening in public schools has stirred sharp controversy with the emergence of letters sent home to parents indicating their child’s BMI percentile and weight category. In Massachusetts, these letters have been deemed, “fat letters,” and have appeared on late night comedy shows, newspapers, and televised news reports. Not only has screening come under harsh criticism, but the inc...

Climate and land cover change are driving a major reorganization of terrestrial biotic communities in tropical ecosystems. In an effort to understand how biodiversity patterns in the tropics will respond to individual and combined effects of these two drivers of environmental change, we use species distribution models (SDMs) calibrated for recent climate and land cover variables and projected t...
