Tackling the remaining attainment gap between students with and without immigrant background: an investigation into the equivalence of SES constructs     

Jenny Lenkeit  Daniel H. Caro  Steve Strand 《Educational Research and Evaluation》2013,19(1):60-83

In England, students with immigrant background exhibit lower educational attainment than those without immigrant background. Family socioeconomic status (SES) helps explain differences in educational attainment, but a gap remains that differs in size for students with different immigrant backgrounds. While the explanatory repertoire for the remaining gap is broad, it has been neglected to comprehensively investigate whether family SES constructs are equivalent across students with different immigrant backgrounds. Using data from the first wave of the Children of Immigrants Longitudinal Survey in Four European Countries (CILS4EU) for England (n = 4,315), the paper applies exploratory structural equation modelling (ESEM) to evaluate measurement invariance of family background constructs across students without and with immigrant background, specifically Pakistani/Bangladeshi immigrant background. Results suggest differences in the structure of family SES indicators across groups and in their association with educational attainment. Complementary variables are suggested to enhance family SES indicators. Findings are relevant to researchers investigating educational inequalities related to immigrant background.  相似文献   

Assessment of Adoption Gaps in Management of Aflatoxin Contamination of Groundnut (Arachis Hypogaea L.)

Abstract

One of the major impediments for diversification of groundnut (Arachis Hypogaea L.) as food crop is aflatoxin contamination. The study was conducted with an objective to assess the adoption gaps in aflatoxin management practices of groundnut (AMPG) and the farmer's characteristics influencing these gaps. The study used an expost-facto research design and multi-stage random sampling. The data were collected from 180 respondents through interview schedule. For measuring adoption gap, knowledge of AMPG and perception of groundnut quality suitable scales were developed. The data were subjected to multiple regression analysis to know the characteristics, which influenced the adoption gaps in AMPG. The majority of farmers were in high adoption gap category, as most of the farmers had not adopted the harvest and post-harvest management practices. Farmers' characteristics such as knowledge, market orientation and innovativeness influenced the adoption gap significantly. These three variables put together explained 58% of variation in adoption gap. Based on the results, it is suggested to formulate strategies to increase the knowledge of farmers through various extension approaches. If the knowledge on AMPG is improved the adoption gaps can be reduced. The maiden research effort, shed light on the socio-economic dimensions of aflatoxin contamination and constraints for aflatoxin management at farmers' level. The study has significance for the policy makers, extension departments and groundnut farmers for production of quality groundnut.  相似文献   

高管薪酬、收入差距与企业绩效关系实证研究——来自中国制造业A股上市公司的经验证据     

梅雨 《嘉应学院学报》2013,(10):37-41

以2012年1 189家中国制造业A股上市公司为样本,实证研究高管薪酬、收入差距与企业绩效之间的关系。研究结果表明,公司高管薪酬与企业绩效显著正相关,公司高管与一般员工的收入差距与企业绩效呈现显著U型相关,从而支持了薪酬激励理论。进一步研究还表明,薪酬激励的效果随公司的实际控制人类型的不同而呈显著的变化,这对不同控制人类型的公司进行适宜的薪酬激励设计和安排具有重要价值。  相似文献

翻译中词汇空缺现象的认知解读     

魏俊民 《四川教育学院学报》2007,23(1):79-81

从认知的角度看,词汇空缺的形成既可能是由于不同的文化或生活经验而导致的概念缺失,也可能是由于不同民族概念化差异而导致的语义域错配(dismatch between semantic fields)。词汇空缺在翻译中可以通过“音译”、“意译”和“诠释”等多种手段进行处理。通过“音译”或“意译”产生的某些“借词”(borrowed word或loan word),久而久之有被目的语吸收,从而弥补词汇空缺的倾向。  相似文献
