This article details an evaluation of a research project based on participatory research methods organized by the Swedish Disability Federation from 2008 to 2011. In Sweden there has been a lack of productive dialogue with the traditional academic world and the question was raised whether proposals for future research would be different if disabled people formulated them. Nine idea-circles with disabled participants and invited researchers from fields of interest close to the participants produced ideas, developed out of the life experience of being a disabled person. These ideas were developed into 72 research drafts that often reflected key advocacy areas, rather than operationalized research issues. The adjustment from the familiar discourse of political struggle to discussion of research was a complicated process for many. When asked to prioritize among areas for research, the representatives from the disability movement chose areas that are not stressed in mainstream disability research in Sweden.  相似文献

This article explores whether trade facilitation – i.e. improved and simplified trade procedures – could be an important part of the reform agenda of the Barcelona Process. Adopting a Southern perspective by focusing on exports to the European Union (EU) from non‐EU Mediterranean countries, it tests whether the efficiency of trade procedures affects (i) bilateral volumes of exports and (ii) the number of products exported. The findings suggest that trade facilitation could lead to substantially increased export volumes and export diversification.  相似文献

The author analyzes the current political regime in Russia as a mild type of authoritarian neopatrimonial regime, based on inertia rather than tradition. He argues that changing conditions are undermining its stability and opening up an opportunity to create a democratic state based on law and capable of modernization.  相似文献

Children's target experiences (as recipients of prosocial peer acts and victims of peer aggression) were investigated for their concurrent and longitudinal associations with prosocial and aggressive behavior. Forty‐four children (initially 22–40 months) were observed in naturalistic interactions with peers during a two‐month period for each of three consecutive years. Results revealed no consistency over time in children's experiences as targets for aggressive or prosocial peer acts, although there was some indication that altruistic target experiences may be stable from the end of the preschool period. Early behavior appeared to affect the way children were later treated by peers, but no support was found for the idea that early target experiences influence later behavior. Prosocial behavior was concurrently and longitudinally associated with prosocial target experiences. Aggressive behavior reduced the likelihood of children being targets of prosocial peer behavior and, over time, also of their being targets of peers’ aggression.  相似文献

ABSTRACT

Restricted canonical correlation analysis and the lasso shrinkage method were paired together for canonical correlation analysis with non-negativity restrictions on datasets, where a sample size is much smaller than the number of variables. The method was implemented in an alternating least-squares algorithm and applied to cross-language information retrieval on a dataset with aligned documents in eight languages. A set of experiments was ran to evaluate the method and compare it to other methods in the field.  相似文献
