We assess empirically the changes in returns to education at the subnational level in Uganda using the Uganda National Household Surveys for 2002–3 and 2005–6. Our results indicate that average returns to schooling tended to converge across regions in the last decade. The overall trend in convergence of returns to schooling took place at all levels of educational attainment and this behaviour in returns to education is mostly driven by the dynamics of returns to schooling in urban areas. We analyse subnational convergence in returns to education and unveil deviant dynamics in Northern Uganda. We discuss the potential challenges to inclusive economic growth in Uganda which are implied by our results.  相似文献

The ratio method is commonly used to the estimation of means and totals. This method was extended to the problem of estimating the distribution function. An alternative ratio estimator of the distribution function is defined. A result that compares the variances of the aforementioned ratio estimators is used to define optimum design-based ratio estimators of the distribution function. Different empirical results indicate that the optimum ratio estimators can be more efficient than alternative ratio estimators. In addition, we show by simulations that alternative ratio estimators can have large biases, whereas biases of the optimum ratio estimators are negligible in this situation.  相似文献

Lights and shadows on sustainability rating scoring   总被引:1,自引:1,他引:0  
Many organizations currently publish sustainability ratings that quantify the sustainability of firms by aggregating scores. These organizations analyze companies in economic, social, environmental and corporate governance terms. However, some of these scores are associated with problems of how positive and negative assessments are offset. This work proposes a methodology for using fuzzy logic in the design of a comprehensive sustainability rating for firms. This technique for measuring sustainability addresses the complexity of the concept and enables the incorporation of expert knowledge into the system of assessment. This approach is applied to organizational information taken from the 2008 Accountability Rating and corrects one of the weaknesses revealed by methodologies based on the aggregation of scores—the offset effect—enabling decision-maker to manage it. This is considered an important research topic because of the growth of social responsible financial markets, and the fact that investors are demanding more accurate information.  相似文献

In this article, we examine the contradictions and lack of consistency between various levels of discourse relating to Roma educational policies. Policy-makers have claimed that political interventions would positively impact the progress of Roma. However, the results have been mixed. We argue here that teachers need to re-evaluate their roles as politically aware and culturally informed agents in order to guarantee social justice to a historically disadvantaged ethnic minority. Based on ethnographical fieldwork carried out over a two-year period with Spanish Roma children, both in schools and in their families, this study shows how intercultural policies have failed to impact the educational realities of Roma children.  相似文献

This study identifies predictors and normative data for quality of life (QOL) in a sample of Portuguese adults from general population. A cross-sectional correlational study was undertaken with two hundred and fifty-five (N = 255) individuals from Portuguese general population (mean age 43 years, range 25–84 years; 148 females, 107 males). Participants completed the European Portuguese version of the World Health Organization Quality of Life short-form instrument and the European Portuguese version of the Center for Epidemiologic Studies Depression Scale. Demographic information was also collected. Portuguese adults reported their QOL as good. The physical, psychological and environmental domains predicted 44 % of the variance of QOL. The strongest predictor was the physical domain and the weakest was social relationships. Age, educational level, socioeconomic status and emotional status were significantly correlated with QOL and explained 25 % of the variance of QOL. The strongest predictor of QOL was emotional status followed by education and age. QOL was significantly different according to: marital status; living place (mainland or islands); type of cohabitants; occupation; health. The sample of adults from general Portuguese population reported high levels of QOL. The life domain that better explained QOL was the physical domain. Among other variables, emotional status best predicted QOL. Further variables influenced overall QOL. These findings inform our understanding on adults from Portuguese general population QOL and can be helpful for researchers and practitioners using this assessment tool to compare their results with normative data.  相似文献

The purpose of this qualitative study was to explore the role that friendship, trust, and love played in the courtship and marriages of eleven German heterosexual couples (twenty-two individuals, including three couples of mixed national heritage) who reported their marriages to be happy. A conceptual model is proposed of how the components of friendship, trust, and love (i.e., love experienced as emotion, behavior, and commitment) may form a foundation for happy German marriages. Identified themes inform suggestions for how these findings can be used by educators, practitioners, and clergy to support and strengthen German marriages.  相似文献

Gibraltar is a community in which political conflicts are common, but has quite frequently been ignored in the academic world, despite its great interest and uniqueness. The present research offers a new perspective into the study of the Gibraltarian identity as it adheres to the theoretical paradigm known as Critical Discourse Analysis (CDA), which analyses language in relation to the social context in which it appears, aiming at providing social criticism based on linguistic evidence. This article focuses on the representation of the Gibraltar issue in a crucial moment for this community – namely the 2002 referendum. The textual corpus consists of editorial articles drawn from Gibraltarian newspapers examining how the Gibraltarian community was perceived and represented. Hence, the present CDA of editorial articles in relation to the referendum held in Gibraltar sheds light on a controversial situation: the Gibraltarian community and its distinctive identity.  相似文献

Modern technologies are frequently used in order to deal with new genomic problems. For instance, the STRUCTURE software is usually employed for breed assignment based on genetic information. However, standard statistical techniques offer a number of valuable tools which can be successfully used for dealing with most problems. In this paper, we investigated the capability of microsatellite markers for individual identification and their potential use for breed assignment of individuals in seventy Lidia breed lines and breeders. Traditional binomial logistic regression is applied to each line and used to assign one individual to a particular line. In addition, the area under receiver operating curve (AUC) criterion is used to measure the capability of the microsatellite-based models to separate the groups. This method allows us to identify which microsatellite loci are related to each line. Overall, only one subject was misclassified or a 99.94% correct allocation. The minimum observed AUC was 0.986 with an average of 0.997. These results suggest that our method is competitive for animal allocation and has some interpretative advantages and a strong relationship with methods based on SNPs and related techniques.  相似文献
