The artistic labor market is marked by several adversities, such as low wages, above-average unemployment, and constrained underemployment. Nevertheless, it attracts many young people. The number of students exceeds the available jobs by far. A potential explanation for this puzzle is that artistic work might result in exceptionally high job satisfaction, a conjecture that has been mentioned at various times in the literature. We conduct the first direct empirical investigation into artists’ job satisfaction. The analysis is based on panel data from the German Socio-Economic Panel Survey. Artists on average are found to be considerably more satisfied with their work than non-artists, a finding that corroborates the conjectures in the literature. Differences in income, working hours, and personality cannot account for the observed difference in job satisfaction. Partially, but not fully, the higher job satisfaction can be attributed to the higher self-employment rate among artists. Suggestive evidence is found that superior “procedural” characteristics of artistic work, such as increased variety and on-the-job learning, contribute to the difference in job satisfaction. 相似文献

Using more processors for parallel turbo decoding is an important issue to speed up the processing at the receiver of a communication system. Butterfly networks used to map the addresses of extrinsic values represent an elegant and simple solution in parallel turbo decoding. Recently, it has been shown that quadratic permutation polynomial (QPP) interleavers allow an easy way to compute the control bits for a butterfly network. In this paper we show that not only QPP interleavers, but any degree permutation polynomial (PP) interleavers and almost regular permutation (ARP) interleavers also allow the same easy way to compute the control bits required in butterfly networks. As a consequence, it is useful to apply the butterfly networks in parallel turbo decoding when using these performant algebraic interleavers. 相似文献

This article is based on surveys undertaken for a British Library Research and Innovation Centre/Library and Information Commission‐funded research project. It describes the models of operation of purchasing consortia in two library sectors (health and higher education) and their expenditure patterns. Present and future savings deriving from consortial activity and the effects of consortia on periodicals suppliers are discussed. The article closes by predicting future activity. 相似文献

Ultrasonic bioacoustics has revealed many examples of animal sounds that are beyond the upper limit of human hearing. In many cases the use of high frequencies confers considerable advantages for communication and these become especially important in the radar-like processes of echolocation. Animals may exploit a wide range of physical principles and they suffer the same natural constraints as man-made systems. Similar problems thus find similar solutions even when more than one approach is possible. 相似文献

This study sets up to test the extent to which gender variety moderates the impact of power disparity on group cognitive complexity (GCC) and satisfaction with the group in a collaborative learning setting. Using insights from gender differences in perceptions, orientations and conflict handling behavior in negotiation, as well as gender differences in exerting social influence in small group settings we hypothesize that gender variety alleviates the negative impact of power disparity on GCC and satisfaction. We test this hypothesis in a sample of 110 student groups and our results show that for high gender variety, power disparity has a small positive effect on GCC, while for low gender variety power disparity has a negative effect on GCC. In a similar vein we show that in gender homogeneous groups, power disparity has a negative association with satisfaction, while for mixed-gender groups the association between the two is not significant. We discuss (1) the implications of these results for the management of diversity in educational and organizational settings and (2) the use of cognitive mapping as a comprehensive evaluation tool for collaborative learning effectiveness. 相似文献
