AbstractIdentity fusion theory proposed that fused individuals have a visceral feeling of oneness with the group and this leads them to engage in radical, violent pro-group behaviours. Other approaches to group extremism link acceptance of violence to right-wing authoritarianism (RWA) and social dominance orientation (SDO). We extended previous research on fusion in three ways. First, by exploring if identity fusion is a significant predictor of the willingness to fight for a group, when controlling for group identification, left-wing authoritarianism (LWA), RWA and SDO. Secondly, we controlled for a membership in a group known for radical action directed at out-groups, namely football hooligans. Finally, we added a second outcome variable, which is the acceptance of violent change of the current social system. The participants were self-described football hooligans (N = 24) and undergraduate students (N = 155). Regression analyses revealed that the strongest predictor of willingness to defend in-group was identity fusion, with RWA and group identification significant as well. RWA and LWA emerged as the strongest predictors of acceptance of violent change. The effect of group membership wasn’t significant. 相似文献

RUTA: A framework for assessing and selecting additive value functions on the basis of rank related requirements 总被引:1,自引:0,他引:1
In this paper, we present a new preference disaggregation method, called RUTA, which infers a set of additive value functions from the preference information referring to the desired ranks of some reference alternatives. Real-life experience indicates that people willingly refer to the range of allowed ranks that a particular alternative should attain, or to constraints on the final scores of the alternatives. We develop a mathematical model for incorporating such preference information via mixed-integer linear programming (MILP). Then, we discuss how decision making could be supported with the use of the already proposed extreme ranking analysis (ERA), which indicates the best and worst ranks gained by each alternative over the set of compatible preference model instances. We also introduce a new interactive UTA-like technique, which aims at selecting a single value function representing the outcomes of ERA. In the interactive process, the decision maker (DM) is assigning priorities to different pre-defined targets, which are built on results of ERA, and refer to the comparison of the best and/or worst ranks for pairs of alternatives. In particular, the DM may choose to emphasize or neglect the advantage of some alternatives over the others, in terms of results of ERA. In this way, one obtains a synthetic representation of extreme ranking analysis at a higher level of abstraction. 相似文献

Physical activity is known to exert beneficial effects on general health status of young, adult and elderly populations. Exercise (aside from genetic, hormonal, nutritional and pathological factors) also influences bone mineral density (BMD). Unfortunately, the association between physical exercise and BMD in adult population is controversial. Our aim was to assess relations between recreational physical activity and BMD in middle-aged men. We performed densitometry and hormonal measurements (total testosterone, free testosterone, dehydroepiandrosterone sulfate, estradiol) in a homogenous group of 38 subjects. Among them, we distinguished 22 who had not engaged in any physical activity, and 16 who had recreationally exercised for about 10 years. Both groups did not differ in regard to hormonal status. Similarly, densitometry did not reveal any statistically significant differences in BMD between both groups of men. Upon our observation, we can hypothesize that recreational physical activity does not affect bone mineral density in middle-aged men. 相似文献

Two topics are presented in this paper: a short history of the Polish economic transformation, begun in 1989, and analyses of aggregate data describing the life conditions of Polish households in the period immediately following the transformation. 相似文献

In this paper we present extensions to the original adaptive Parallel Tempering algorithm. Two different approaches are presented. In the first one we introduce state-dependent strategies using current information to perform a swap step. It encompasses a wide family of potential moves including the standard one and Equi-Energy type move, without any loss in tractability. In the second one, we introduce online trimming of the number of temperatures. Numerical experiments demonstrate the effectiveness of the proposed method. 相似文献

This study seeks, using state-level data, to identify key factors that help to explain recent trends of labor force participation
among women. Adult females are treated as attempting to maximize utility subject to a variety of budgetary and non-budgetary
constraints. Among the findings obtained is a positive impact from the level of public assistance, i.e., the greater the extent
of public assistance to adult females in the forms of Supplemental Security Income, Food Stamps, and so forth, the higher
the female labor force participation rate (FLFPR). Other factors contributing to observed FLFPRs include age, the presence
of young children, family income, educational attainment and disability status. In addition, we also find evidence that an
increase in the proportion of the population that is non-native to the U.S. has a negative effect on the FLFPR.

conclusion We empirically evaluate two issues: (1) how the union rent seeking responds to import competition and (2) whether union bargaining
power, as proxied by the proportion of the labor force in an industry that is unionized, moderates the impact of import com-petition
on union wage differentials. Unlike other studies, our emphasis is on the influ-ence of import competition on union rent seeking, rather than on union wages per se. Our primary results indicate that while import competition negatively and significantly affects union rent seeking,
the extent of unionization does not substantially influence the impact of import competition on the union wage differentials.
This is a somewhat surprising result since the literature suggests that union wages are greater in the pres-ence of stronger
unions. 相似文献

We analyse the genetic variability in the yellow-necked mouse (Apodemus flavicollis) population in the city of Warsaw, Poland, and its surroundings - a species that has begun to occupy the city only in the last 30 years. We also compare the genetic variability of this species with corresponding data collected in the same time and areas for another species - the striped field mouse (Apodemus agrarius). The results indicate a gradual decrease in genetic diversity and increase in relatedness in the population of A. flavicollis from non-urban locations towards sites with the highest anthropopressure. The genetic structure was more pronounced in the 'recent invader' (A. flavicollis) than in the 'permanent inhabitant' (A. agrarius), which has a much longer city colonization history (more than 100 years). In general, FST was higher in A. flavicollis, which may indicate different and independent ways of city colonization by the species. The process by which urban areas are settled by a new, typically forest-dwelling species such as A. flavicollis, more 'sensitive' to the conditions of life in a city, probably includes not only successful events of penetration of the city by small groups of individuals (the founder effect), but also temporary extinctions of local urban populations of A. flavicollis or at least marked fluctuations in species population numbers. Suitably planned areas at the city borders could play an important role as 'gateways' through which individuals from non-urban populations could migrate into the city and join urban populations. 相似文献
