Today's European Union was founded in a 1950s marked by its member states' involvement in numerous colonial conflicts and with the colonial question firmly entrenched on the European and international agenda. This notwithstanding, there is hardly any scholarly investigations to date that have examined colonialism's bearing on the historical project and process of European integration. In tackling this puzzle, the present article proceeds in two steps. First, it corroborates the claim that European integration not only is related to the history of colonialism but to no little extent determined by it. Second, it introduces a set of factors that explain why the relation between the EU and colonialism has been systematically neglected. Here the article seeks to identify the operations of a colonial epistemology that has facilitated a misrecognition of what postwar European integration was about. As the article argues, this epistemology has enabled colonialism's historical relation to the European integration project to remain undetected and has thus also reproduced within the present EU precisely those colonial or neo-colonial preconceptions that the European partner states, in official discourse and policy, falsely claim that they have abandoned.  相似文献

Exploiting the exogenous variation in user fees caused by a Swedish childcare reform, we are able to identify the causal effect of childcare costs on fertility in a context in which childcare enrollment is almost universal, user fees are low, and labor force participation of mothers is very high. Anticipation of a reduction in childcare costs increased the number of first and higher-order births, but only seemed to affect the timing of second births. For families with many children we also find a marginally significant negative income effect on fertility.  相似文献

Studies of mobility within both sociology and economics most commonly use a conventional classification of social or economic origin, based on the position of the father only. The questions raised in the paper is whether there has been a trend towards more economic mobility, and whether conclusions about change based on a joint classification of both mother and father differ from those based on conventional classifications. These questions are addressed on the basis of register data on the earnings of the total Norwegian population of mothers, fathers and children from 1967 and onwards. The analyses focus on the earnings of the cohorts born between 1955 and 1970, and their earnings at the age of 34–35. The results do not support the argument in previous research that intergenerational economic mobility has increased in Norway. Moreover, the results based on a conventional approach differ from those based on a joint classification including the earnings of both mother and father. Using the latter approach there is no indication of a trend towards greater openness.  相似文献

The lower extremity performance in elderly female patients with mild to moderate Parkinson's disease (PD; n = 12) and controls (n = 16) was compared. Isometric dynamometry and force-plate measurements were used. PD patients had lower (p < .05) bilateral (BL) maximal isometric leg-extension force (MF), BL isometric MF relative to body mass, and maximal rate of isometric force development than control participants. BL strength deficit was greater (p < .05) in PD patients than in controls. A significantly longer chair-rise time and lower maximal rate of vertical-ground-reaction-force development while rising from a chair was found in PD patients than in controls. These findings suggest that elderly women with PD have lowered voluntary isometric force-generation capacity of the leg-extensor muscles. Reduced BL leg-extension strength might contribute to the difficulty of individuals with PD to rise from a chair.  相似文献

Regression models for survival data are often specified from the hazard function while classical regression analysis of quantitative outcomes focuses on the mean value (possibly after suitable transformations). Methods for regression analysis of mean survival time and the related quantity, the restricted mean survival time, are reviewed and compared to a method based on pseudo-observations. Both Monte Carlo simulations and two real data sets are studied. It is concluded that while existing methods may be superior for analysis of the mean, pseudo-observations seem well suited when the restricted mean is studied.  相似文献

La crise contemporaine de la vie rurale et agricole c'est produite simultanément avec une crise de la pensée et de la recherche critique: une analyse basée sur l'engagement à créer une société plus rationelle, démocratique et égalitaire. L'économie politique, le paradigme prédominant, a contribuée de façon importante à l'identification et à l'analyse des méchanismes économiques sur lesquels se développent la crise sociale. Mais celui-ci n'a tenu aucun compte d'enquêter sur la façon dont une crise est vécue par ceux qui en sont le plus touchés, et sur les perspectives de changement queue crise du genre peut offrir. Ceci est due d'un côtéà la nature des hypothèses théoriques de l'économie politique, ainsi que sur la façon dont les économistes politiques utilisent les méthodes des sondages dans leurs travaux empiriques. En utilisant les ressources offertes par la theorie sociale et les résultats de recherche primaire et empirique, cet article suggère de nouvelles directions pour la recherche critique de la vie rurale. Nous expliquons que ce genre de recherche devrait devenir plus hermaneutique et phénoménologique dans le but de concentrer sur les perceptions, l'analyse personnelle et les activités de ceux qui vivent dans les milieux ruraux, surtout lorsque ceux-ci essaient de préserver leurs communautés contre l'influence de l'extérieur. II n'est plus nécessaire, de présumer que les chercheur(e)s et leur sujets doivent demeurer détachés si la recherche est sérieusement scientifique et érudite. Cet article considère certaines implications théoriques, empiriques et historiques qu'apporte cet argument. The contemporary crisis in agriculture and rural life has been paralleled by a crisis in critical thinking and research: analysis informed by the commitment to a more rational, democratic and egalitarian society. Political economy, the currently dominant critical paradigm, has made important contributions to the identification and analysis of the economic mechanisms through which social crisis develops. But it has by and large failed to probe both the ways in which crisis is actually experienced by people enduring it and the real possibilities for change that a crisis situation might offer. This failure stems both from the nature of the theoretical assumptions which inform political economy and the manner in which political economists deploy methods of survey research in their empirical work. Using both the resources of social theory and the results of empirical, primary research, this paper attempts to suggest new directions for critical research into rural life. J t argues that this research should adopt a more explicitly hermeneutical and phenomenological focus which should put the perceptions, self-understandings and activities of rural people themselves, particularly as they strive to preserve their communities against outside forces, more fully at the centre of analysis. No longer should it be assumed that researchers and those studied must remain separate if research is to be truly scholarly and scientific. The paper addresses some possible theoretical, empirical and historical  相似文献

We examined how satisfied Finnish adoptive parents were with statutory pre-adoption counselling in inter-country adoptions. The data were collected through the Finnish Adoption Study using a retrospective survey measuring satisfaction with received pre-adoption counselling. All adoptive parents with a child under the age of 18, adopted from abroad between the years 1990 and 2007, were included. The sample of the study comprised parents of 1451 children and a total response rate of 55.7% was achieved. The data consisted of self-scored reports of satisfaction as well as open answer questions. Parent satisfaction and associated variables were analysed using chi-square and multiple logistic regression. Of the respondents, 81.7% reported satisfaction with the pre-adoption counselling they had received. The level of satisfaction was stable over time and did not differ according to service provider, whereas family type and sending country were associated with satisfaction. However the explanations for satisfaction were different for those services provided in units specialized in adoption and for those provided by municipal child protection services. The components found to explain satisfaction and dissatisfaction were experience, adoption knowledge, and attitude of the social worker, service accessibility and availability issues, as well as the content of the pre-adoption counselling offered.  相似文献

This paper deals with the analysis of data from a HET‐CAMVT experiment. From a statistical perspective, such data yield many challenges. First of all, the data are typically time‐to‐event like data, which are at the same time interval censored and right truncated. In addition, one has to cope with overdispersion as well as clustering. Traditional analysis approaches ignore overdispersion and clustering and summarize the data into a continuous score that can be analysed using simple linear models. In this paper, a novel combined frailty model is developed that simultaneously captures all of the aforementioned statistical challenges posed by the data.
