Knowledge about the long-term influences of climate change on the amount of potential carbon (C) sequestration in forest ecosystems, including age-related dynamics, remains unclear. This study used two similar age-sequences of black locust forests (Robinia pseudoacacia L.) in the semi-arid and semi-humid zones of China's Loess Plateau to assess the variation in C stocks and age-related dynamics...

This paper examines Australian household data from over 4000 individuals to assess how downwardly flexible nominal wages have been during the period 1997 to 2000. The data indicate that there is considerable downward rigidity. Only 7.4 per cent of workers who are still working the same hours in the same job experienced a cut in pay over the previous year. People in lowincome households, unskill...

Executives have high stakes riding on executive skill accumulated in their non-CEO executive positions in order to establish themselves as talented before being on the competitive CEO market. This paper considers an assignment model augmented by costly pre-CEO executive skill accumulation on the job. As the firm size distribution is more spread to the right, causing the increase in firm size, t...

Horizontal wells are proven to be better producers because they can be extended for a long distance in the pay zone. Engineers have the technical means to forecast the well productivity for a given horizontal length. However, experiences have shown that the actual production rate is often significantly less than that of forecasted. It is a difficult task, if not impossible to identify the real ...

Investigations were performed to better understand the carbon economy in the elongation zone of tall fescue leaf blades. Plants were grown at constant 21 degrees C and continuous 300 micromoles per square meter per second photosynthetic photon flux density where leaf elongation was steady for several days. Elongation occurred in the basal 20 mm of the blade (0-20 millimeters above the ligule) a...

We obtain global solutions of radiatively inefficiently accretion flows around black holes. Whether and where convection develops in a flow are self-consistently determined with the mixing-length theory. The solutions can be divided into three types according to the strength of normal viscosity. Type I solution corresponds to large viscosity parameter α>∼ 0.1, which is purely advectiondominated...

Psychobiography was invented by Sigmund Freud while investigating the psychological determinants of Leonardo da Vinci’s artistic creativity. Following the founder of psychoanalysis there were about 300 psychobiographic analyses published until 1960. From the 1930’s psychoanalysis also influenced the unfolding personality psychology trend called personology in the USA, led by G. W. Allport and H...

To elicit an affected population’s preferences for, e.g., better health or environment stated preference (SP) methods are often used. SP methods are based on hypothetical market settings which necessitates validity tests of the results. This study describes a validity test on the basis of theoretical predictions and empirical findings for private and public safety measures. According to the tes...
