产学合作实施人才培养是高职教育取得成效的重要途径。基于现代服务业岗位群对人才“软性”智力技能等的特殊要求,目前较为普遍的商科类高职院校产学合作基本模式存在的路径依赖、显性职业素质培养途径固化以及实训机制不健全等影响了人才培养的效果。商科类高职院校有必要找准产学结合点。通过创建多元实践联合体、培育教师科研综合能力、完善实践平台等策略推动产学合作模式的升级,走出一条开放式的产学合作道路。 相似文献

《诗经》中,婚恋诗所占的篇幅颇丰,它们充分展现了先民们的婚约缔结过程:在《诗经》的时代,周礼所规定的婚姻“六礼”就已通行于贵族及平民阶层,但婚姻仪式又因社会阶级地位的不同而有所区别;周代主要的婚姻形式除以一夫一妻为标志的聘娶婚外,还有一夫多妻的媵妾婚、亡夫亲属收娶寡妇的收继婚和野合而婚;与此同时,《诗经》中又不乏弃妇诗,从这些诗篇出发可以分析先民婚姻的事实终结的部分原因,从而窥测整个周代婚姻形态的大端。 相似文献

This study aimed to investigate the scholarly information-seeking behavior of academic engineers and technologists working at the University of the Punjab. The purpose of the study was to investigate the various information sources being used by academic engineers and technologists for their scholarly tasks, with a focus on use patterns of e-journals. A quantitative study employing “survey” method was conducted to achieve the research objectives. A self-administered questionnaire was distributed to all regular and contractual academic engineers and technologists working at the university and a response rate of 61% was achieved. The study findings showed that the respondents' most-used information sources were e-journals, e-books, discussion with colleagues, and electronic research reports. They accessed e-journal articles through general search engines, Google Scholar, and open access e-journal websites. Majority of the respondents used e-journals for keeping themselves up-to-date and supervising researchers. While previous studies have investigated academic and practitioner engineers' information-seeking habits, this study is valuable as it investigated academic engineers' and technologists' scholarly information-seeking behavior in relation to their e-journals use patterns. 相似文献

With the globalization in education, there has been an influx of Chinese students studying in the United States. The needs and challenges of understanding their backgrounds and their perceptions about libraries are becoming more present and urgent for librarians who are on the frontline of serving this special cohort. To discover and address the growing needs and challenges, we surveyed 42 Chinese students at Kennesaw State University, analyzed the data collected, and discussed the research results. Our goal is to identify the characteristics common to this group and to provide some insightful information to our fellow librarians. 相似文献

This study investigates the factors determining children's educational attainment, focusing on gender-differential intergenerational patterns, by employing a case study from rural Mindanao. The result mainly shows, unlike general trends in developing countries, educational attainment is more favorable for girls; maternal education level is equally associated with daughters’ and sons’ education levels, and paternal education level is preferentially favorable to their sons. To reduce the disparity, suggestions include providing boy-specific interventions to enhance the magnitude of the father–son educational virtuous circle and comparing the magnitude of gender-equal maternal and boy-preferential paternal education influences to specify which effect is larger. 相似文献
