The refugee sanctuary movement in the United States has shifted to include undocumented immigrants fleeing violence and economic strife. Given the negative tenor of coverage of undocumented immigration, and ties between framing and policy views on immigration, how the media frames sanctuary cities is likely to impact public perceptions of these cities and their policies. To assess media coverage of sanctuary policies, we analyzed articles from five national newspapers from 1980 to 2017 with both human content analysis and dictionary-based computational analysis. We find that framing around religion/morality and conflict has decreased, while stories focusing on crime and partisanship have increased. We discuss implications for public opinion and the likelihood that the American public will take their cues from media framing and elite discourse when it comes to sanctuary policies.  相似文献

Currently available web page accessibility guidelines focus more on reading and writing, with inadequate attention to other aspects of online learning such as computer-mediated communication. This study aims to explore the engagement of Malaysia secondary school students with dyslexia and students without dyslexia on various synchronous and asynchronous communication interaction technologies in an online collaborative learning environment. Multiple case within subject qualitative study was employed to investigate the engagement of students using a semi structured interview guideline. The findings revealed that (1) text chat is unsuitable for learning discussion for all learners, (2) forum affords self-paced and organized formal discussion for most learners and (3) video conferencing is suitable for interactive face-to-face, verbal discussion for most learners.  相似文献

This study examined the variables associated with student satisfaction on a commuter campus. A sample of 38 classes was used and resulted in 782 undergraduates responding to questionnaires. The variables included were: age, student level, student's grade, perception of educational benefits, and satisfaction with college experience. A causal model was built and tested in order to determine the direct and indirect effects of these variables upon student satisfaction. While the student level had a negative influence upon satisfaction, both age and grade had a moderate effect upon student satisfaction. The perception of educational benefits seemed to be the most critical variable in predicting student satisfaction.  相似文献

ABSTRACT

Males (n = 29) and females (n = 34) performed vertical jumps. Jump height was estimated from force platform data using five numerical methods and compared using intraclass correlation (ρ), and linear and rank regression standard error of estimate (SEE). Take-off velocity plus center of mass height at take-off and mechanical work methods were identical (ρ = 1.000) with small linear (SEE < 0.0001 cm) and rank order (SEE = 0) error. Integrating acceleration to displacement was nearly identical (ρ > 0.999), with small linear (SEE = 0.1 cm) and rank order (SEE < 1) errors compared to the above methods. Take-off velocity (ρ = 0.517) and flight time (ρ = 0.573) estimates were less than all other methods and had large linear (SEE ≥ 2.1 cm) and rank order (SEE > 4) errors. Take-off velocity and flight time methods should be avoided due to systematic and random error.  相似文献

土壤肥力变化的社会经济影响因素分析   总被引:10,自引:1,他引:10  
自然过程和人类活动是影响土壤质量演变的两大因素,而人们的农业生产行为对农田土壤肥力的影响日益加深。中国人口众多,土壤资源有限,其80年代初以来的农地土壤肥力变化备受世人关注。同时中国农村的经济、制度、政策发生了深刻的变化。本文利用80年代初和2000年的土壤肥力数据以及相应的社会经济调查数据,试图揭示自农村改革以来可能影响土壤肥力变化的社会经济和政策因素及其相互关系。初步分析表明,经济发展水平对土壤肥力提高有一定促进作用,耕地资源禀赋则相反。现行土地产权制度与土壤肥力变化之间没有表现出某种明显的相关关系。20年来中国农地的复种指数变化没有破坏土壤肥力,反而因复种指数微略下降而改善土壤肥力。同时近年来秸秆还田的增加有助于提高土壤有机质含量。  相似文献
