The CCR model by Charnes et al. (Eur J Oper Res 2:429–444, 1978) together with the BCC model by Banker et al. (Manag Sci 30:1078–1091, 1984) are the most popular approaches of measuring efficiency among a group of decision making units, DMUs, in data envelopment analysis, DEA. The right choice of a DEA model—CCR or BCC—often, if not always, is a difficult decision. To evaluate a DMU’s efficiency for both models might be helpful, but it does not always capture the essential issues at stake. In this paper we propose a comparative analysis of both concepts: How does activity scaling under constant BCC-efficiency influence CCR-efficiency. And inversely, how does BCC-efficiency behave when activity scaling under constant CCR-efficiency is applied. Such findings of mutual effects improve a DMU’s ability to reassess upsizing and downsizing of activities. Moreover, it allows for exact calculations of the resulting economic effects, and these effects give new insights beyond classical DEA. Finally, scale efficiency turns out to be the ideal concept to control these activity changes, rather than just CCR- or BCC-efficiency. We use a little numerical example to emphasize advantages of the new concept and sketch the new findings for a theater scenery.  相似文献

The aim of this paper is to investigate whether women in a dual-earner context acquire family-friendly jobs as a strategy to keep work–family conflict down. The analysis is based on a survey of newly graduated highly educated men and women in five occupations in Sweden (n?≈?2400). The sample was stratified by occupation and gender to minimize the influence of factors other than gender. The results show that women are more family-oriented, but also more career-oriented than men in their professional strategies. In their jobs, women have less control over work and schedules than men but a similar level of work demands. However, women face lower requirements for employer flexibility (e.g. frequent over time) and this is related to their professional strategies. Finally, women report a higher level of work–family conflict than men in the same occupation, but this gender difference becomes non-significant when accounting for women’s lower level of control. In sum, women in this sample clearly aim for both family and career and do not acquire family-friendly jobs, but aim to avoid ‘family-unfriendly’ requirements for constant availability. To some extent, this enables them to limit their work–family conflict but due to their lower control over work, women still experience more conflict than men in the same occupation.  相似文献

Infant negative affectivity predicts child anxiety. Coparenting might influence the development of anxiety by weakening this association in the case of supportive coparenting, or by strengthening this association in the case of undermining coparenting. Parents can display coparenting behaviors simultaneously (both parents being supportive or undermining), or divergently (only one parent being supportive or undermining). In our longitudinal study, we investigated whether coparenting moderated the relation between infant negative affectivity at 4 months and child anxiety symptoms 2 years later. Hundred‐sixteen couples dressed up their firstborn infants in a clothes‐changing task. We coded cooperative, mutual, neutral, and competitive coparenting behaviors. Both parents rated infant negative affectivity and child anxiety symptoms. Infant negative affectivity significantly predicted child anxiety. This association was moderated by parents' divergent cooperative coparenting: It was stronger when mothers were cooperative while fathers were neutral, and weaker when fathers were cooperative while mothers were neutral. When fathers step forward (i.e., being cooperative) and mothers step back (i.e., leaving space), they may protect their at‐risk child from developing anxiety.  相似文献

Public debates about the rise in top income shares often focus on the growing dispersion in earnings, and the soaring pay for top executives and financial-sector employees. But can the change in the marginal distribution of earnings on its own explain the rise in top income shares? Are top executives replacing capital owners in the group of top-income earners, or are we rather witnessing a fusion of top capital and top earnings? This paper proposes an extension of the copula framework and uses it for exploring the changing composition of top incomes. It illustrates that changes in top income shares can easily be decomposed into respective changes in the marginal distributions of labour and capital income and the changing association between the two types of income. An application using tax record data from Norway shows that the association between top labour and capital incomes grew stronger between 1995 and 2005 in the top half of the wage and capital income distribution, though it declined for the top 1% of capital income receivers. A gender decomposition demonstrates that the association of wage and capital incomes at the top is particularly striking for men, whilst women are largely under-represented in the top halves of the two marginal distributions.  相似文献

We examine the process of Gentrification in two residential areas of Cologne, Germany: Deutz and Mülheim. The theory underlying the study is a phase (or stage) model of Gentrification in which indicators and their values are attributed to each phase. The hypotheses derived from the model pertain to changes in the social structure, rents and the spatial distribution of social groups such as “pioneers”, “gentrifiers” and “others”. We further assume both areas to be in different phases of Gentrification.  相似文献

This article studies the payment of wages to castle slaves at Cape Coast Castle (in current-day Ghana) in the eighteenth century. A quantitative estimate shows that the wages paid to these slaves were considerably higher than subsistence costs. A large sample of wage payments is also used in order to analyse statistically the existing wage differentials among the slaves. The results indicate that a complex wage structure had been developed in order to incentivize the slaves to work and to foster loyalty towards the slaveholder.  相似文献

The study focuses on dilemmas in storied experiences of everyday after‐school care arrangements among Swedish and Finnish mothers. Finland and Sweden, which share a history of strong labour market attachment among women, arrange institutional after‐school care in similar ways. The data consist of interviews with three Swedish and six Finnish mothers. A positioning analysis of four stories shows how decisions related to children's after‐school hours were allocated among different actors. Two reoccurring dilemmas, Competent‐dependent child stories and Unburdened‐deficient mother stories, emerged from the data analysis as related to prevailing moral discourses on childhood and motherhood.  相似文献

This article explores whether it is possible to use a theoretical framework drawn from disability studies to understand experiences of social oppression on the grounds of mental distress. Thomas’ extended social relational theoretisation of disablism was used in a PhD project concerned with experiences of mental distress. The tentative conclusion was that Thomas’ conceptualisation of disablism and impairment could offer a way of improving understanding of mental distress and oppression on the grounds of mental distress. However, Thomas and Reeve’s theorisation of the different forms of disablism was not readily transferred to the field of mental distress. Thus, tentative definitions of the different forms of disablism in relation to the field of mental distress were created. Perceived impairment type and disablism appear to be interconnected, and one has to acknowledge what kind of perceived impairment type one is focusing on when theorising disability and the different types of disablism.  相似文献

Transformational leaders are known to inspire and motivate their followers, thereby leading to enhanced job satisfaction. Job satisfaction is an intellectual concept regarding individuals’ attitudes toward their jobs. This study asserts that the underlying mechanisms for transformational leadership to affect employee satisfaction are trust in the community, including the leader (that is, organization) and trust in the self, namely self‐efficacy. Leadership is specifically associated with continual transformations in the higher educational context, and collectivist cultures may manifest different processes underlying the transformational leadership–satisfaction relationship. This study investigated the mediating effects of trust and self‐efficacy on the relationship between transformational leadership and job satisfaction. The study sample included academicians from a nonprofit higher education institution in Turkey. The data were analyzed using structural equation modeling. The results showed that the relationship between transformational leadership and job satisfaction is fully mediated by both trust and self‐efficacy. The mediator effect of trust was shown to be stronger than self‐efficacy, which is assumed to be the result of the cultural context. The results are discussed in the context of employee satisfaction and cultural determinants of employee satisfaction.  相似文献

This study examines three-year post-baseline outcomes for a randomized controlled trial of Swedish antisocial youths who received either multidimensional treatment foster care (MTFC) or treatment as usual (TAU). Several studies in our literature review indicated that MTFC intervention is preferred to the alternative (TAU) in the USA during follow-up. Two studies (one conducted in the UK and one in Sweden) have shown indications of a washout effect between the intervention alternatives during follow-up. However, this study showed few but positive significant outcomes at follow-up for the MTFC programme in comparison to TAU. Juveniles who participated in MTFC spent fewer days in locked settings and had committed fewer violent crimes, according to the social case records. Two key features of the MTFC programme certainly merit use in general social service—namely, reducing exposure to deviant peers and increasing school participation.  相似文献
