ABSTRACT

The idea that pornography promotes sexism is a commonly purported one. This study employed an online sample of heterosexual men (N = 323) to investigate the relationship between pornography use (in terms of both overall level of pornography use and use of violent and/or humiliating pornography) and old-fashioned and modern sexism. The moderating effects of agreeableness and perceived realism of pornography were also assessed. Level of general pornography use and use of violent and/or humiliating pornography was not predictive of either sexism measure. Agreeableness was negatively predictive of both sexism measures, whereas perceived realism was positively predictive of sexism. Agreeableness and perceived realism did not moderate the relationship between level of pornography use and any of the outcome measures.  相似文献   

Health-related fitness knowledge growth in middle school years: Individual- and school-level correlates     

Xihe Zhu  Justin A. Haegele  Haichun Sun 《运动与健康科学(英文)》2020,9(6):664-669

BackgroundHealth-related fitness knowledge (HRFK) has been an essential concept for many health and physical education programs. There has been limited understanding and longitudinal investigation on HRFK growth. This longitudinal study examined HRFK growth and its individual- and school-level correlates in middle school years under 1 curriculum condition: Five for Life.MethodsParticipants were 12,044 students from 47 middle schools. Data were collected at both individual/participant and school/institution levels. Individual-level variables included gender, grade, and HRFK test scores. School-level variables included percentage of students receiving free and reduced meals (FARM), student-to-faculty ratio for physical education, and school academic performance (SAP). We used hierarchical linear modeling to examine HRFK 3-year growth in relation to individual- and school-level correlates.ResultsThe average HRFK score at 6th grade for females was 42.81% ± 1.32%. The predicted HRFK growth was 17.06% ± 1.02% per year, holding other factors constant. A 1-standard deviation increase in FARM correlated with a 14.68%-point decrease in predicted test score (p = 0.02). A 1-standard deviation increase in SAP was associated with an 11.90%-point increase in HRFK score. Males had a significantly lower growth rate than females during the middle school years (0.78%/year, p = 0.02).ConclusionThe result showed that both individual- and school-level variables such as gender, FARM, and SAP influenced HRFK growth. Educators should heed gender differences in growth curves and recognize the correlates of school-level variables.  相似文献

依托“一带一路”建设构建运动休闲产业新经济带研究     

周〓丹  宋〓波 《广州体育学院学报》2020,(2):32-34

习近平主席提出"一带一路"的理念和经济发展战略规划,标志着我国经济发展以及外交事务进入了一个新的历史阶段,但从经济发展的角度看,这个理念把过去经济发展,特别是国家经济联系的点对点的模式拓展成为一个多方合作共赢的立体网状空间,这为新时期经济发展模式拓展了空间和思路。运动休闲产业作为中国的新型产业,过去对西方国家的依赖太重,这个并不受西方技术壁垒的产业之所以难称民族产业,原因在于西方产品与理念在我国市场上占据了先入为主的优势,"一带一路"建设为我国运动休闲产业的发展或者说起飞提供良好的契机,构建"一带一路"运动休闲产业经济带是我国运动休闲产业全面发展的重要基础。  相似文献

去留之间:农村小学全科教师离职倾向研究——以重庆市为例     

袁丹  周昆  刘子龙 《中国教育学刊》2020,(4):97-99

农村小学全科教师能否在岗位上"留下来"是人们普遍关心的问题。对重庆在职农村小学全科教师的调查发现,人际关系、个人观念、家庭生活、组织支持等因素在其去留之间发挥着平衡、缓冲和调节作用。稳定农村小学全科教师队伍,需要不断改善外部环境,提高其存在感;强化组织支持,提升其获得感;坚定个人信念,提质其价值感。  相似文献

Educator‐Reported Instructional Characteristics of Grade 1 Reading Interventions within a CBM Assessment System     

Joseph F. T. Nese  Dan Farley  Daniel Anderson 《Learning disabilities research & practice》2019,34(2):97-109

We used data from the 2014–2015 easyCBM assessment system to explore the applied reading intervention characteristics in a sample of 3,074 Grade 1 students (and 5,145 interventions) in school districts applying a multitiered systems of support (MTSS) framework. We describe the number of interventions, number of assessments, the intervention start dates, curricula, instructional strategies, tier, group size, frequency, dosage, total time, and quantitative intensity. We found variance across all instructional variables, with 156 curricula and 59 instructional strategies applied. Based on our data, a “typical” intervention was a Tier 2 intervention that began before October, was delivered for 30 minutes/day for 5 days/week in a group with three to five students, was changed once if at all, and student progress was most likely monitored with word reading fluency measures.  相似文献
