The contribution reviews the state oft the art of the research on general success factors in the coaching process. Research in the field of psychotherapy on basic variables of client centered counseling and general therapeutic change mechanisms set an example. Results of first studies on these and modified factors show that the coaching outcome depends on observed esteem and emotional support by the coach, resource activation and support of transfer into practice. Process analysis of nonverbal interactions between coach and client demonstrate that goal attainment influence goal attainment. Finally, the paper focuses on limitations, of the studies, scientific and practical conclusions as well as future perspectives. 相似文献

Unions, particularly in Germany, are the subject matter of intense public debates as well as discussions in academic research, which corroborate the former. The last systematically conducted analysis of the status quo in academic research was done in spring 2001. In view of the rather dramatic symptoms of the crisis German unions are facing, it is time to incorporate the latest results of scientific research. This paper addresses this task against the background of a systematic literature review. Three application areas are distilled out of a total of 79 pieces of research that are considered relevant and intensively discussed: (1) the membership in German unions, (2) the unions in the German system of industrial relations and (3) the reformation of the German unions. The detected symptoms of the unions' crisis are impressively documented and explained by the studies. However, shortcomings regarding the respective research questions and the development of recommendations for future courses of action for the unions can also be identified. 相似文献

This essay examines a maritime case involving a Charleston-based French privateer in 1795 as well as members, subjects, and citizens of multiple societies from Western Africa, Cuba, Spain, and Great Britain in order to reveal the fluid legal foundations of trans-Atlantic regimes with respect to slavery and freedom. The French maritime seizure of a British slaving vessel in the Caribbean and the subsequent transfer of enslaved African peoples from British to French to Spanish authority in Cuba set the stage for nearly 40 years of litigation in both hemispheres. The case led to legal disputes in Philadelphia, Madrid, and Havana as members of this Atlantic society sought to confront the most prominent political and social issues of this era. While officials in Philadelphia sought to avoid entanglement in the imperial wars between France and Great Britain, officials in Madrid and Havana competed with each other in order to define the legal identities of a group of Carabalí-Oru peoples onboard the British vessel. For their part, this group of Carabalí-Oru peoples exploited the ambiguities created by a system of Atlantic jurisprudence while relying on their memory of the Middle Passage in order to challenge their unjust enslavement in Cuba. 相似文献

The estimation of variance-covariance matrices through optimization of an objective function, such as a log-likelihood function, is usually a difficult numerical problem. Since the estimates should be positive semi-definite matrices, we must use constrained optimization, or employ a parametrization that enforces this condition. We describe here five different parametrizations for variance-covariance matrices that ensure positive definiteness, thus leaving the estimation problem unconstrained. We compare the parametrizations based on their computational efficiency and statistical interpretability. The results described here are particularly useful in maximum likelihood and restricted maximum likelihood estimation in linear and non-linear mixed-effects models, but are also applicable to other areas of statistics. 相似文献

Slack-variable models are compared against Scheffé's polynomial model for mixture experiments. The notion of model equivalence and the use of various diagnostic measures provide effective tools in making such comparisons, particularly when the experimental region is highly constrained. It is demonstrated that the choice of the best fitting model, through variable selection, depends on which mixture component is selected as a slack variable, and on the size of the fitted model. In addition, the equivalence of two well-known representations of a complete mixture model is shown to be valid. Two numerical examples are presented. 相似文献

This article explores why women delay childbearing and increase their likelihood to remain childless in Spain, Italy, West
Germany and France. We take a macro–micro perspective and show that national institutions influence women’s life transitions,
in particular partnership and motherhood. For coupled women, we find two alternative modes out of childlessness. In countries
with high direct and indirect child costs, like Spain and Italy, entering a male-breadwinner couple or occupying a stable
and high-income position facilitates motherhood, while in the French context motherhood is most likely in a dual-earner partnership.

Low back pain is a costly and incapacitating musculoskeletal disorder. Prospective studies documenting the capacity of work-related factors to predict chronicity are few in number, the methodology used is very diversified, and the results obtained diverge. The aim of the present study is to investigate the capacity of work-related objective (non-psychosocial) and psychosocial factors to predict chronic disability related to low back pain. A longitudinal prospective study with two measurement times was carried out. The sample (N = 258) consisted of workers with subacute low back pain who were on sick leave and receiving compensation from the CSST (Quebec Workers' Compensation Board). Of all the work-related variables measured, perceived stress and fears and beliefs about work were associated with return to work status at the six-month follow-up. The results obtained show the importance of considering fears and beliefs about work when identifying people in the subacute phase of low back pain who are at risk of developing chronic disability. 相似文献

Collective and Unitary Models: A Clarification 总被引:3,自引:0,他引:3

In this note we identify and clarify a confusion that has arisen in the literature about the exact relationship between unitary
and collective models and what enters the Pareto weight and the sharing function. We suggest that we should denote as ‘unitary’
any model that leads to outcomes that satisfy the Slutsky conditions whether or not these outcomes depend on distribution
factors. In particular, income pooling is neither necessary nor sufficient for a unitary model. We also show that the presence
of prices or total expenditure in the sharing rule cannot be used as a test for a unitary model.
