采用问卷法对北京市897名流动儿童的主观社会经济地位、社会自尊、公正世界信念和问题行为进行问卷调查,探讨主观社会经济地位与问题行为的关系,并进一步考察公正世界信念的中介作用和社会自尊的调节作用。结果发现:(1)主观社会经济地位与社会自尊、公正世界信念呈显著正相关,主观社会经济地位、社会自尊、公正世界信念与问题行为呈显著负相关。(2)公正世界信念在主观社会经济地位与问题行为的关系中起中介作用。(3)社会自尊调节主观社会经济地位通过公正世界信念影响问题行为的中介路径。社会自尊水平较高时,公正世界信念的中介作用显著; 社会自尊水平较低时,公正世界信念的中介效应不显著。  相似文献

The vast majority of Malaysia's fishermen are located in rural areas, specifically in the Western and Eastern coastal regions of Peninsular Malaysia and the Sabah and Sarawak central zones. In these areas, the fishing industry is relied upon as a major economic contributor to the region's residents. Despite the widespread application of various modern technologies into the fishing industry (i.e., GPS, sonar, echo sounder, remote sensing), and the Malaysian government's efforts to encourage their adoption, many small‐scale fishermen in the country's rural areas continue to rely on traditional fishing methods. This refusal to embrace new technologies has resulted in significant losses in fish yields and needed income, and has raised many questions regarding the inputs to decision making of the fishermen. Drawing on multiple literatures, in this article we argue for the use of a mental model approach to gain an in‐depth understanding of rural Malaysian fishermen's choices of technology adoption according to four main constructs—prior experience, knowledge, expertise and beliefs or values. To provide needed inputs to agricultural specialists and related policy makers for the development of relevant plans of action, this article aims to provide a way forward for others to understand dispositional barriers to technology adoption among fishermen who use traditional methods in non‐Western contexts.  相似文献

According to the Spatial Agency Bias (SAB), more agentic groups (men) are envisioned to the left of less agentic groups (women). This research investigated the role of social status in shaping the spatial representation of gender couples. Participants were presented pairs consisting of one male and one female target who confirmed gender stereotypes. The status of the targets in each pair was systematically varied (high-status vs. low-status job). Participants chose the target order (female/male vs. male/female) they preferred. In line with gender-status expectations (male: high-status, female: low-status), a male in a high-status job led to a spatial arrangement that favored the male/female order, regardless of the status of the female target. The female/male order was favored only when the female had a high-status job and the male a low-status job. No SAB occurred for pairs in which both targets displayed low-status jobs. The implications of status for the SAB are discussed.  相似文献

This study utilized data from the evaluation of the Finnish KiVa program in testing the prediction that school bullies' high perceived popularity would impede the success of anti-bullying interventions. Multiple-group structural equation modeling (SEM) analyses were conducted on a subsample of 911 third-, fourth-, and fifth-graders identified as perpetrators of bullying. They belonged to 77 Finnish schools, including 39 schools implementing the KiVa program and 38 control schools. Data on peer-reported bullying and perceived popularity were collected before program implementation and one year later. Controlling for sex, age, and initial levels of bullying, KiVa participation resulted in lower rates of bullying (indicated by fewer peer nominations) after one year for bullies of low and medium popularity. However, there was no significant effect for those high in popularity, suggesting that popular bullies are less responsive to anti-bullying interventions than less popular bullies.  相似文献

在宁夏回族地区如何开展临终关怀工作和提高临终关怀工作的质量,根据在宁夏回族地区开展临终关怀工作五年的实践体会,分析了宁夏主要由于社会老龄化的压力、家庭结构的变化和宁夏疾病死因顺位变化原因开展临终关怀的必要性。探讨了目前宁夏临终关怀面临的七个主要问题,即热心从事临终关怀的专业人员少、临终关怀机构缺乏、社会重视度低、心理治疗严重不足、社会义工资源短缺、医院与外界对临终关怀医护人员的关怀少和患者及家属对临终关怀治疗的期望值高。总结了在宁夏开展临终关怀实践的六点体会。  相似文献

随着辅助生殖技术的不断发展,越来越多暂时不需要进行移植的胚胎存放在生殖医学中心.然而,由于各种伦理争议及社会舆论压力,生殖中心往往会困惑于“无主胚胎”的处理.2013年6月,美国生殖医学协会伦理委员会对“无主胚胎”进行了确切的定义并给出了处理意见和指导原则,结合我国实际国情,从“无主胚胎”定义、“无主胚胎”现状、“无主胚胎”的处理方式及伦理争议、对生殖中心的建议四个方面进行阐述,以求为生殖中心在“无主胚胎”处理方面提供相应帮助.  相似文献

ObjectivesThe present study tested a motivational sequence in which children's goals for leisure-time sport and physical activity (PA) from Goal Content Theory predicted pedometer-determined PA through behavioural regulation constructs from Self-Determination Theory.DesignQuantitative cross-sectional study.MethodsA sample of 1272 Flemish (Dutch speaking part of Belgium) sixth graders (M age = 11.42 years) filled in a questionnaire on PA goal content, behavioural regulations and pubertal status. Children's height and weight were measured to assess Body Mass Index (BMI). To measure daily PA behaviour, participants wore a pedometer for seven consecutive days. Structural equation modelling was performed to test the proposed motivational sequence and to examine the mediation effect of behavioural regulations towards leisure-time sport and PA on the relation between PA goal content and daily step counts.ResultsA structural equation model supported the hypothesized sequence in which intrinsic goals for leisure-time sport and PA predicted children's daily step counts through autonomous motivation towards leisure-time sport and PA. Multi-sample invariance testing revealed that the proposed model was largely invariant across BMI groups, pubertal status and gender.ConclusionsThe findings highlight the importance of emphasizing intrinsic goals for participation in leisure-time sport and PA in children aged 10–12 years. By stimulating children to participate in PA and sports by referring to intrinsic goals, children are more likely to enjoy PA, which in turn might increase the likelihood of a regular and long-term PA engagement.  相似文献

ObjectivesSingle mothers experience negative health consequences that might be reduced through participation in physical activity, yet little is known about physical activity correlates among this population. This study examined social cognitive theory (SCT) correlates of physical activity among single mothers with young children.DesignCross-sectional.MethodSingle mothers (N = 94) with at least one child less than 5 years old completed SCT questionnaires, wore an accelerometer for one week, and then completed the Godin Leisure Time Exercise questionnaire. Physical activity scores were standardized and averaged to yield a composite physical activity score.ResultsRegression analysis indicated that self-efficacy was a direct predictor of composite physical activity; in the final model planning was the only statistically significant predictor of composite physical activity scores.ConclusionsPlanning and self-efficacy might be important factors to include when designing physical activity interventions for single mothers.  相似文献

The purpose of the current study is to examine the relationship between socioeconomic status, parental control, and authoritarianism in Iran. A sample of 460 students was surveyed from Shahid Chamran University of Ahvaz in Iran. Results demonstrated that subjective socioeconomic status, parental control, and parents' education have significant influence on authoritarianism. Further analysis showed that parental control partially mediates parents' education association with authoritarianism with a relatively high effect size. These findings highlight the importance of parental control and socioeconomic status in the development of authoritarianism in Iran. Furthermore, the higher authoritarianism of low socioeconomic status is mostly due to lower education levels rather than the income of the family. The findings were discussed with regards to literature as well as the socio‐cultural sphere of Iran.  相似文献
