This paper investigates how the recruitment and selection for project-based postdoc positions are organised in the current academic landscape characterised by increasing temporary research funding and how principal investigators construct the ‘ideal’ postdoc. Our findings are based on a qualitative comparative multiple-case study in Social and Natural Sciences departments of universities in four European countries. This study contributes to the literature on the neoliberal university and academic staff evaluation by using a systemic, power-sensitive approach that examines how postdocs enter the academic system and how manifestations of precarity are exacerbated. Our critical analysis reveals three manifestations of precarity that the current academic system creates for postdocs, related to control, contracts, and careers. We discuss the effects for individual postdocs and their careers and the quality of knowledge production in public funded higher education institutions. 相似文献

This paper presents an empirical analysis of the role of land fragmentation, crop biodiversity and their interplay with farm profitability. Original primary data are drawn from a survey conducted in the Plodiv region of Bulgaria. The econometric results stress the ambiguous role of land fragmentation on farm profitability. On one hand, land fragmentation reduces farm profitability. On the other hand, land fragmentation fosters crop diversification. We also find that crop biodiversity plays a beneficial role in farm profitability. Policies that aim to increase land consolidation and reduce fragmentation may overlook the positive link between diversity and plot heterogeneity. Policies that encourage land consolidation should, therefore, consider the crucial role that this has on other variables such as farm biodiversity. 相似文献

The continuing process of global integration bears implications for farmers and related supplying and processing industries in all parts of the world, but also for the rest of the world economy. An assessment of agricultural and trade policy impacts is bound to be complex and is often supported by quantitative modeling analysis. This article provides an assessment of the present state of applied modelling in the area of trade and agricultural policies. We provide in this paper a comparative assessment of alternative modelling approaches, considering a total of 16 partial equilibrium and general equilibrium models. The assessment includes theoretical modelling foundations, datasets employed and institutional aspects, such as model maintenance and dissemination of results. A typology of models is provided by structuring the assessment along a clear set of evaluation criteria. 相似文献

This collection of papers by sociologists and anthropologists focuses on the effect of tourism on the maintenance, transformation, and re-creation of ethnic boundaries. Tourism is seen as a special form of ethnic relations, particularly that form of tourism in which the cultural exoticism of the host population is the principal attraction for the tourist. This type of tourism leads to the formation of three main roles: tourist, touree, and middleman. The authors address different aspects of the marketing of ethnicity, such as the role of the state in the development of ethnic tourism; the modification and recreation of ethnic attributes and consciousness as the result of tourism; the transformation of art forms through the tourist trade; the role of the tourist agent; and the formation of ethnic stereotypes in tourist interactions. 相似文献

Within the field of future studies, the scenario method is frequently applied. In the literature it is often stressed that it is important to know as soon as possible which of several scenarios is closest to the course of history as it actually unfolds. However, tracking scenarios via early warning mechanisms or signposts, is not a common practice. A standard methodology seems to be absent. Within the context of the Justice for tomorrow project, a scenario project of the Dutch ministry of Justice, we developed and applied a signpost method. We used this method to answer the question of how actual developments relate to the development paths depicted in the scenarios. In this paper we evaluate our approach. We explain what lessons can be learned regarding the use of signposts in future studies. 相似文献

This paper concerns the estimation of granular property price indices in commercial real estate and residential markets. We specify and apply a repeat sales model with multiple stochastic log price trends having a hierarchical additive structure: One common log price trend and cluster specific log price trends in deviation from the common trend. Moreover, we assume that the error terms potentially have a heavy tailed (t) distribution to effectively deal with outliers. We apply the hierarchical repeat sales model on commercial properties in the Philadelphia/Baltimore region and on residential properties in a small part of Amsterdam. The results show that the hierarchical repeat sales model provides reliable indices on a very detailed level based on a small number of observations. The estimated degrees of freedom for the t-distribution is small, largely rejecting the commonly made assumption of normality of the error term. 相似文献
