Existing approaches within leadership studies often share a bias towards industrialized societies and lack broader cross-cultural and ethological reference. Meanwhile, cross-cultural and evolutionary approaches within anthropology are actively working to unify research on leadership and followership across the biological and social sciences. This review provides a novel and thorough view of political leadership as investigated by evolutionary anthropologists and highlights the benefits of incorporating findings from the evolutionary social sciences into leadership studies generally. We introduce the anthropological approach to leadership; describe evolutionary anthropology, its subdisciplines (including primatology, paleoanthropology, paleogenetics, human behavioral ecology, and gene-culture coevolution), and its complementary disciplines (particularly evolutionary psychology); review leadership and hierarchy in nonhumans, including our extinct hominid ancestors; review female leadership and sex-differences; and, primarily, discuss the relationships between evolution, ecology, and culture as they relate to the observed patterns of political leadership and followership across human societies. Through evolutionary anthropology's diverse toolkit, a deeper insight into the evolution and cross-cultural patterning of leadership is realized. 相似文献

The article aims to contribute to the understanding of competitive dynamics and specialization in international sport by analyzing superior sporting performance (SSP) in international athletics in the period from 1999 to 2018. By applying iterative Kolmogorov‐Smirnov tests to annual bests, the study examines national SSPs. Contrary to theoretical considerations, less specialized countries are more likely to achieve SSP. Technical entry barriers and macrosocial factors also appear to play a limited role. SSP seems not to disappear due to increased international competition. The United States and Russia are identified as “sporting super powers,” able to persistently dominate a number of disciplines. The case of Russia poses fundamental questions concerning market distortions in international sport resulting from doping. The results come with substantial policy implications. 相似文献

Pensions with a strong tax–benefit link (Bismarck pensions) minimise the labour–leisure distortion of the public pension system.
By contrast, pensions with a strong link of benefits to the number of children (child pensions) minimise the fertility distortion.
When both types of distortion are present, we obtain a Corlett–Hague result regarding the optimal mix of the two pension formulae:
the Bismack pension should be given a positive weight if and only if children are more complementary to leisure than consumption.
Alternative fertility instruments such as child benefits turn out to be perfect substitutes to a child pension. 相似文献

In 2004 a new working time law for physicians in hospitals was introduced, which has up until now been rarely researched in theory and is implemented in practice partially in form of new working time models, partially by relying on allowed variation rules within the law. Meanwhile, there are new discussions about changes of working time directives on the European level. This article aims to analyze the desired effects of the new working time law to decrease the workload, improve the possibilities of patient care and increase the working time satisfaction of physicians. To this end, a primary data collection is conducted in 15 hospitals and 35 hospital departments, generating 261 questionnaires, in order to empirically assess the theoretical model with the constructs working time model, workload, working time satisfaction, and possibilities of patient care using regression analyses. It can be shown that the new working time models decrease workload and enhance working time satisfaction of hospital physicians, but have no significant influence on the possibilities of patient care. These results are consistent for different ownerships and sizes of hospitals as well as for most services. No significant differences in the answers between various physician groups exist either. 相似文献

Classical multivariate methods are often based on the sample covariance matrix, which is very sensitive to outlying observations. One alternative to the covariance matrix is the affine equivariant rank covariance matrix (RCM) that has been studied in Visuri et al. [2003. Affine equivariant multivariate rank methods. J. Statist. Plann. Inference 114, 161–185]. In this article we assume that the covariance matrix is partially known and study how to estimate the corresponding RCM. We use the properties that the RCM is affine equivariant and that the RCM is proportional to the inverse of the regular covariance matrix, and hence reduce the problem of estimating the original RCM to estimating marginal rank covariance matrices. This is a great computational advantage when the dimension of the original data vector is large. 相似文献
