This study examined 587 Turkish adolescents’ (Mage = 13.14, SD = 1.61) judgments and bystander responses towards hypothetical intragroup interpersonal (Turkish victim) and intergroup bias-based (Syrian refugee victim) bullying. Intergroup factors and social-cognitive skills were assessed as predictors. Findings revealed that adolescents were less likely to see bullying as acceptable and less likely to explicitly support the bully in intragroup interpersonal bullying compared to intergroup bias-based bullying. Further, adolescents with higher theory of mind and empathy were more likely to evaluate intergroup bias-based bullying as less acceptable and more likely to challenge the bully. Adolescents’ prejudice and discrimination towards refugees were predictors of bystander judgments and responses to intergroup bias-based bullying. This study provides implications for anti-bullying intervention programs. 相似文献

Seven tests of univariate normality are studied in view of their asymptotic power under local alternatives. The procedures under consideration are either based on the empirical skewness and/or kurtosis, including the popular Jarque-Bera statistic, as well as Cramér-von Mises, Anderson-Darling and Kolmogorov-Smirnov functionals of an empirical process with estimated parameters. The large-sample behavior of these test statistics under contiguous sequences is obtained; this allows for the computation of their associated local power curves and of their asymptotic relative efficiency in the light of a measure proposed by Berg and Quessy (2009). Comparisons are made under four classes of local alternatives, including those used by Thadewald and Büning (2007) in a recent Monte-Carlo power study. These theoretical results are related to empirical ones and many recommendations are formulated. 相似文献

This study examined the relationship of perceived neighborhood environment factors with recommended volume and intensity of walking in recreational senior walkers. A sample of 85 seniors used an accelerometer and completed the ALPHA questionnaire. Binomial logistic regressions were conducted to detect associations. Perceptions about traffic safety (odds ratio [OR] = 4.395; 95% confidence interval [CI] = 1.024; 18.866) and pleasant environment (OR = 8.718; 95% CI = 1.803; 42.149) were positively related with the achievement of 10,000 steps per day, in older women. The perception of nearby parks was positively associated with the compliance with peak 30-minutes cadence above 100, in older men (OR = 14.353; CI 95% = 1.321; 15.591). No more significant associations were found between perceptions of the neighborhood environment and walking at recommended intensity and volume levels. These results indicated that community initiatives that encourage traffic safety, pleasant environment, and parks may be a promising direction to promote walking at recommended volume and intensity in senior walkers. 相似文献

The two-sided power (TSP) distribution is a flexible two-parameter distribution having uniform, power function and triangular as sub-distributions, and it is a reasonable alternative to beta distribution in some cases. In this work, we introduce the TSP-binomial model which is defined as a mixture of binomial distributions, with the binomial parameter p having a TSP distribution. We study its distributional properties and demonstrate its use on some data. It is shown that the newly defined model is a useful candidate for overdispersed binomial data. 相似文献

Despite decades of policy aimed at the maintenance of Francophone communities in Ontario, the proportion of individuals with French as a mother tongue or who speak French most often at home has steadily declined. Research on language retention has highlighted the importance of sociodemographic and structural factors in understanding minority language practices. However, given the relationship between culture and action, this paper examines how cultural factors contribute to Franco‐Ontarians’ linguistic practices. Results indicate that beyond couple composition and the concentration of minority‐language speakers, cultural factors including identity, cultural consumption, and values play an instrumental role in Franco‐Ontarians’ linguistic continuity. The importance of considering linguistic continuity as part of a “package” of cultural practices is discussed. 相似文献

Recent studies have suggested that a relationship could exist between 25-hydroxyvitamin D [25(OH)D] deficiency and erectile dysfunction (ED). The present study evaluated the relationship between 25(OH)D levels and ED in male patients with type 2 diabetes mellitus (DM). The study included 98 patients with type 2?DM aged between 18–80 years. The International Index of Erectile Function (IIEF-5) Questionnaire was administered. The patients were divided into three groups according to IIEF-5 scoring: IIEF-5 score between 5–10, severe ED; IIEF-5 score between 11–20, moderate ED; IIEF-5 score between 21–25, no ED. Biochemical parameters, 25(OH)D and hormonal analysis tests were obtained in all patients. All parameters were compared between these three groups. Of 98 patients included in the study, 32 had severe ED, 45 had moderate ED and 21 had no ED. The mean age was 55.12?±?9.39 years and the mean 25(OH)D level was 13.69?±?8.15?ng/ml. When the three groups were compared, 25(OH)D levels were significantly lower in patients with the IIEF-5 score between 5–10 (p?=?0.020). There was a moderate positive relationship between IIEF-5 score and 25(OH)D level (r?=?0.21, p?=?0.038). The patients with severe ED have considerably lower 25(OH)D levels. 相似文献

Correcting household survey distribution data for missing income or for undersampling may give an idea of the extent of possible biases in measuring inequality, especially when there are reasons to expect the missing income and people to belong to the top of the distribution. There are simple ways to do so when only an aggregate estimate of how much is missing is available. Atkinson had provided a formula to correct the Gini coefficient for the missing income, which was later generalized by Alvaredo (Econ. Lett. 110(3), 274–277 2011). This paper concentrates on the whole distribution and explores various alternative adjustment methods based on three key parameters: how much income, how many people are missing and on what range of income the correction should bear. 相似文献

Parents can actively seek knowledge (solicitation) or receive information provided willingly by the child (disclosure). In adolescence, disclosure is the main source of parental knowledge, but its importance may take root earlier in the course of development. We examined: 1) the factor structure of an instrument adapted for middle childhood measuring maternal perception of knowledge, solicitation, and children's self-disclosure; 2) changes in these dimensions over middle childhood; and 3) the respective contribution of solicitation and disclosure to parental knowledge. The mothers of 793 elementary school students (61.5% boys, 80.2% Canadian-born) completed a questionnaire annually from Grades 1 to 4. Multilevel confirmatory factor analysis confirmed the instrument's structure at all time points. Growth curve analyses showed that mothers’ perception of knowledge slightly declined from Grades 1 to 4. With respect to mothers’ perceived parental solicitation and child disclosure, gender interactions emerged. Solicitation declined for girls but remained stable for boys, while disclosure declined for girls but increased for boys over time. In addition, mothers' perception ofdisclosure and solicitation are both main sources of maternal knowledge regardless of age and gender in middle childhood. 相似文献

In this paper is remarked that “mixed” strategies in games of electoral competition do not need to be interpreted as random
moves. There are two a priori symmetric parties, and a finite (non spatial) set of alternatives. Parties are allowed to take
unclear positions, by campaining on a “platform” that is a mix of several alternatives. Each individual nevertheless identifies
a party with a single alternative, the number of individuals who identify a party with a given alternative being proportional
to the importance of that alternative in the party’s platform.
