中央情报局对1962年中印边界冲突的评估与美国政府的应策

自1959年西藏叛乱起,中印边界纠纷不断,最终于1962年发生了大规模的冲突。美国政府相当重视中印两国的这场大规模边界冲突。对于这一紧急情况,美国政府立即利用中央情报局对当时中印边界形势的发展做出评估,从一个侧面反映了美国政府在中印边界冲突紧急阶段的心理预期和应对之策。     

试论竞争情报工作的合法化

As competition requires fair law environment, competitive intelligence work should obey the rules of law, too. This article elaborates the legalization of competitive intelligence work from three aspects its necessity, manifestation and law system. Competitive intelligence tends to develop in the direction of standardization, and legalization is the inherent character of competitive intelligence.     

Computer science and engineering: utilizing action research and lesson study

ABSTRACT

This article explores one group’s use of action research (AR) and lesson study in three US university-level computer science courses affecting 85 undergraduate computer science and engineering students. It offers an overview of three areas including AR, lesson study, and engineering soft skills. The research group identified a problem: undergraduate engineering student soft skill understanding. The group collaborated to enhance participant engagement with this problem by utilizing one lesson focused on soft skills over three research lesson iterations in three distinct university semesters (2017-2018). Field notes were the main data collection method. Observational field notes were recorded in the three research lesson iterations, and themes from the notes were identified. The group valued peer interactions, and the research lesson adaptations as well as pedagogical changes were based on evidence. Four themes were identified, and participant comments were considered as the lessons became more focused . The research group argues that AR and lesson study are separate and distinct ventures based on this yearlong experience, which is counter to some other literature presented. Implications are large for all stakeholders interested in AR, lesson study, soft skill utilization, conflict management, and participant learning impact. Possibilities for enhanced participant engagement exists with honed lesson pedagogy.

经济全球化的挑战与选择

经济全球化是世界经济发展的一个客观过程,它是一股不以人们的意志为转移的巨大潮流,经济全球化在给各国带来空前发展机遇的同时,也给各国尤其是发展中国家带来了前所未有的挑战,面对经济全球化的机遇与挑战,我们必须认清本国在经济全球化过程中的地位,主动地接受世界市场的运行机制,按世界市场的规划办事,屏弃传统的“国家迷信”,不断地根据世界市场的变化调整国家的宏观经济调控政策,并且加强与世界市场中所有行为体的合作,只有这样,我们才能把握住历史发展的潮流,使自己立于不败之地。     

Attachment insecurity accounts for the relationship between maternal and paternal maltreatment and adolescent health

ObjectivesMaltreatment is linked with poor health outcomes. Attachment and affect regulation may mitigate the long-term impact of these adverse experiences on health outcomes. Little is known about the relative impact of maternal versus paternal maltreatment and interparental violence (IPV) on general health status of female and male youth.MethodThe present study examined the impact of exposure to maternal and paternal emotional and physical maltreatment, neglect, IPV, and cumulative maltreatment exposure in adolescence on general physical health problems reported five years later. High-risk youth (N = 179; Mage = 15.34, SD = 1.53; 46.4% female) self-reported maltreatment experiences, attachment insecurity, and affect dysregulation at Time 1; and affect dysregulation and physical health five years later at Time 2.ResultsAttachment insecurity accounted for the effect of maternal and paternal emotional maltreatment, and maternal and paternal cumulative maltreatment exposure, on physical health. Additionally, attachment insecurity accounted for the effect of paternal neglect on physical health. Further sex differences were found with regard to maltreatment type and are discussed.ConclusionBoth maternal and paternal maltreatment in adolescence predicted poor general health five years later via attachment insecurity. Youth who lack a secure attachment with their parents are most vulnerable to these impacts.     

环境规制的技术进步效应及其异质性研究——基于我国271个城市面板数据的实证检验

强化环境规制、保护生态环境是实现人与自然和谐发展的必然选择,然而日益趋紧的环境规制是否会影响技术进步,是学界一直争议的问题。为深入分析环境规制对于技术进步的影响,本文选取了中国271个城市的数据作为研究对象,从时间、空间等多视角分析了二者关系。主要结论如下:在时间维度上,滞后一期后,环境规制的技术进步正效应达到最大;在空间维度上,东部地区环境规制的技术进步正效应最大,西部最小;环境规制对技术进步的影响存在双重门槛效应,过高或过低的环境规制均不利于技术进步。因此,各地区应根据自身实际发展情况动态调整环境规制强度,可通过建立碳排放交易市场和其他污染物排放交易市场使得企业更加灵活地达到环境规制要求。
