With strong pressure to make academic research socially and economically relevant, academics face the problem of reconciling inherently academic products through which they are assessed (e.g. scientific articles) with other products that are often demanded by non-academic social actors. These products, which we call scholarly couplers, make up an important part of academic work, often ignored or underestimated in evaluation instances. In this article, we show how these types of products articulate with traditional ones and argue that academic production should be observed (and evaluated) through heterogeneous product chains, fostering more diverse academic profiles.  相似文献

On looking at the female labour supply in Europe, it is immediately noticed that there is a large variation among countries. One possible explanation for this fact is that different countries have different tax policies, leading to variations in incentive and costs. This has been investigated in papers such as that of Gustafsson (1992a,b) for countries such as Germany and Sweden. The same exercise has been performed by the present authors for a low-income, southern European country, Portugal, which has one of the highest rates of female participation (out of line with neighbouring countries). Female labour supply does not seem to be very sensitive to fiscal policies, as those policies have only a small influence on the take-home wage. This result appears to be independent of the fact that the female labour supply shows a higher elasticity to wages than that which has been reported for other countries. The present authors also show that Portuguese women contribute a much larger proportion of family earnings than do their counterparts in Sweden and Germany, and that the Portuguese fiscal system is rather neutral. Further studies with data from other countries are needed in order to shed more light on the issue of tax harmonization.  相似文献

High-performance work practices (HPWPs) enacted within public sector undertakings (PSUs) in emerging economies are a relatively underexplored topic. By employing the theoretical lens of social exchange and the ability, motivation and opportunity paradigm, this paper highlights the mediating effects of knowledge sharing on the relationship between employee perceptions of HPWPs and employee and business unit performance. We provide evidence drawn from both manager- and employee-level voices by applying a qualitative case study design to two large Indian PSUs and taking a reverse/inverse approach in order to delineate the commonly understood conceptualizations of HPWPs. Our findings confirm the presence of a combination of high-commitment, high-involvement and high-performance work systems that increase the ability, motivation and opportunity of employees to share knowledge, and thus help achieve positive employee and financial outcomes. We found that our set of HPWPs exhibit a strong paternalistic welfarism ethos. We also discuss the implications of our study for research and practice.  相似文献

The Neotropical region has been subjected to massive urbanization, which poses high risks for some global biodiversity hotspots and losses of ecosystem functions and services. In this study, we investigate how distance from large patches of native forests (source areas) and vegetation (green)/and infrastructure (gray) characteristics affect bird species richness and functional diversity in São Paulo megacity, southeastern Brazil. We analyzed the effects of source areas and green/gray characteristics on species richness and functional diversity (richness, evenness, and divergence) indices. We detected 231 bird species, and our data confirmed our predictions: (1) bird species richness in urbanized habitats was found to be (~?50–85%) lower than in source habitats; (2) species richness and trait composition significantly decreased as the distance from the source area increased, while functional richness was not affected by this metric; and (3) shrub and herbaceous covers and maximum height of trees were positively correlated with species richness and unique functional traits regarding habitat, diet, foraging and nesting strata and dispersal ability of birds in the forest-urban matrix. The number of buildings was negatively correlated with bird species richness and functional richness. Maximum height of buildings caused dramatic declines in functional evenness. Functional divergence was notably lower in sites with high shrub cover. Our study stresses the complexity of vegetation embedded in large Neotropical urban settlements and the need to maintain large protected areas surrounding megacities to mitigate the impacts of urbanization on birds.

A variable-centered and a person-centered approach were performed to examine the role of early memories of warmth and safeness (EMWS) and current experiences of warmth and safeness (CEWS) on depressive and anxious symptoms among adolescents from community and residential youth care (RYC) settings. Variable-centered results revealed EMWS were only indirectly (through CEWS) associated with depressive and anxious symptoms. Person-centered outcomes allowed to identify four different profiles based on EMWS and CEWS, which differed on depressive and anxious symptoms. EMWS and CEWS seem to play an important role in psychological distress during adolescence. CEWS seem to have a protective role on RYC adolescents' psychological distress, even when EMWS were poor.  相似文献

This article presents the results of a longitudinal study that followed a sample of 1011 young people who completed their secondary technical and vocational education and training studies in Chile between 2011 and 2016. It adopts a mixed design that combines both quantitative and qualitative methodological strategies to analyse transitions and post-study trajectories. Analysis has helped to identify the prevalence of non-linear and unstructured transitions to the labour market. It has also shown the existence of education-work links and employment alternatives that are generated in certain sectors as well as identified how these give rise to specific opportunity structures that affect on aspirations and career pathways. Results indicate that graduates of the industrial area of study experience more substantive educational integration and labour links following course completion due to greater levels of alignment between their training and the productive demands of the industrial sectors. However, their experiences over the medium term are fragmented and, thus, reflect those of their peers from other areas.  相似文献
