矿业工程非学历教育缓解人才供需矛盾

矿业企业地处边远山区,工作条件差,学生不愿意选择矿业工程领域的专业学习,再加上目前矿业发展迅速,对人才的需求量剧增,导致矿业工程技术各层次人才供不应求。为了解决矿业工程技术人才的供需矛盾,除了高校扩大人才学历培养的规模外,矿业企业自身根据需要,结合工业生产各个环节,采用非学历教育方式进行人才培养和培训是可行的,也是必要的。     

现代大学的社会责任--读《走出象牙塔--现代大学的社会责任》

大学逐步走出“象牙塔“,传统的中立地位受到质疑.大学想要发挥其在当今社会的真正作用,就必须审视自己的社会责任.学术自由是大学的基本价值标准,是维持大学活力的源泉.从学术角度看,大学对社会的责任主要有:让所有的人享受教育;鼓励学生思考社会问题,促进学生道德的发展,提高社会整体道德素质;通过学术研究、技术转让、创造新的产品和产业,最终刺激生产力的发展;考虑科学发明的利用价值和可能产生的不良后果;对外技术援助等.从非学术角度看,大学有对城市、社区的服务责任,对待社会问题的政治立场,对社会捐赠接受的态度以及与校外组织的关系等.总之,现代大学必须承担教育的责任;既适应社会,又要服务社会,引导社会前进的责任;走向世界,实现国际化是现代大学的重要标志.     

财政补助、研发投入与企业财务风险——基于A股上市公司的证据

对现行研发投入财政补助规定分析发现,财政补助在激励企业增大研发投入的同时也会增大企业财务风险,财政补助门槛会造成企业研发投入集中分布在略高于门槛比例要求的水平上.运用2010-2018年A股上市公司数据的实证显示,企业财务风险水平与研发投入比例和财政补助比例显著正相关,销售收入为5 000万元～2亿元的企业研发投入比例集中分布在4％～5％,销售收入大于2亿元的企业研发投入比例集中分布于3％～4％,研发投入比例略低于门槛要求的企业明显偏少.建议有关财政补助认定标准中引入企业财务风险水平管控指标,在激励企业加大研发投入的同时促进企业管控财务风险;适当降低财政补助企业研发投入门槛要求,弱化企业为博取财政补助而采取过度冒险、增大研发投入行为.     

大力发展风险投资事业 促进高新科技成果的转化

我国的风险投资事业起步于 １９８４ 年,十几年来虽有发展,但仍不适应高新科技成果转化的需要。只有从政策上大力扶持和引导,建立并完善有关法律法规,进一步拓展风险投资渠道,加强对风险投资基金的管理,防范风险投资的风险,才能使我国的风险投资事业走上健康的道路,从而促进高新科技成果的转化

Focusing on the Whole Student: An Evaluation of Massachusetts's Wraparound Zone Initiative

We used a comparative interrupted time series design to examine the impact of the Massachusetts' Wraparound Zone Initiative on student achievement, attendance, retention, and suspension. This initiative was designed to create coordinated district systems that allow schools to proactively and systematically address students' nonacademic needs. The state education agency awarded grants to seven high-need districts, each of which used the funds to support a select group of schools in implementing strategies that focused on school climate and culture, family engagement, systems to identify and address student needs, and community partnerships. Results from this study showed that students in Wraparound Zone schools performed better on state academic assessments than students in comparison schools, when considering prior achievement trends. Effects were statistically significant in the 3rd year of implementation. The impact on academic achievement was greatest for third- and fourth-grade students, and was particularly strong for English learners. There was no statistically significant overall impact on attendance, retention, or suspension.     

Digital technology adoption and knowledge flows within firms: Can the Internet overcome geographic and technological distance?

Under what conditions does digital technology adoption increase cross location knowledge flows within firms? We investigate this question by studying the impact of adopting basic Internet access on cross-location knowledge flows within the same firm. We construct a large data set of Internet adoption and patent citations among dyadic pairs of firm-locations between 1992–1998. We find that when both locations in the pair adopt basic Internet there is an increase in the likelihood of a citation between the citing and (potential) cited location. In contrast, we find no significant effect of Internet adoption at only the citing location. We further study how this effect varies according to the proximity of the research activities between the source and recipient of knowledge and specialization of the research activities within the recipient. We find that the likelihood of a citation increases more after dyadic Internet adoption when the pair is working in similar research areas and when the research areas in the citing location are less specialized. These results, which are robust to a range of robustness analyses, suggest that digital technologies such as Internet connectivity are able to facilitate knowledge flows between locations only when they share a common knowledge base.
