制约当前高职教育质量提高的因素分析及对策

从招生规模扩大、办学经费不足、师资队伍建设滞后、实践教学薄弱、缺乏创新性质量监控与评价体系和人才培养与社会需求不相适应6个方面，分析了制约当前高职教育教学质量提高的因素，并提出了具体的解决对策。     

产品组合决策模型的适用性比较分析﹡

目前广泛使用的产品组合决策模型包括矩阵模型和定量模型两大类别。二者各有其使用价值,其中矩阵模型更适合做产品组合经营战略选择的工具,而定量模型特别适合投资组合的投资优先顺序的确定决策。但是传统产品组合决策定量模型及其现代使用的作业成本法和约束理论都存在一定缺陷而影响其使用效力。为了使决策定量模型更为合理化和适用化,尚需综合考虑产品的市场受欢迎度和不受欢迎产品的处理成本等综合市场竞争因素,优化决策模型,使改进后的决策模型更适应强烈市场竞争下的企业产品组合决策。     

Graphical Techniques for Selecting Explanatory Variables for Time Series Data

Bayesian model building techniques are developed for data with a strong time series structure and possibly exogenous explanatory variables that have strong explanatory and predictive power. The emphasis is on finding whether there are any explanatory variables that might be used for modelling if the data have a strong time series structure that should also be included. We use a time series model that is linear in past observations and that can capture both stochastic and deterministic trend, seasonality and serial correlation. We propose the plotting of absolute predictive error against predictive standard deviation. A series of such plots is utilized to determine which of several nested and non-nested models is optimal in terms of minimizing the dispersion of the predictive distribution and restricting predictive outliers. We apply the techniques to modelling monthly counts of fatal road crashes in Australia where economic, consumption and weather variables are available and we find that three such variables should be included in addition to the time series filter. The approach leads to graphical techniques to determine strengths of relationships between the dependent variable and covariates and to detect model inadequacy as well as determining useful numerical summaries.     

地理距离、方言文化与劳动力空间流动

本文基于百度迁徙大数据研究中国劳动力的空间流动，系统考察地理和文化对劳动力流动的影响。通过构造流动机会比率，基于引力模型和普通最小二乘法的研究表明地理距离和方言距离阻碍劳动力流动。在空间距离上，劳动力偏好邻近城市，地理距离每增加1%，劳动力的流动机会比率降低约0.6%。在空间位置上，劳动力倾向于在方言文化相近地域范围流动，方言距离每增加1%，劳动力的流动机会比率下降2%左右。通过构造两地年均降水量差距和小麦种植适宜度差距作为方言距离的工具变量，以两阶段最小二乘法估计缓解内生性问题，估计显示结论稳健。考虑普通话因素后方言距离的抑制影响依然稳健，但目的地的高普通话普及率显著发挥促进劳动力流动的引力作用。最后，本文得出持续推广普通话、加强交通建设和深化中等教育的政策建议。     

内蒙古地区师范类蒙授英语专业教学模式的研究——以内蒙古民族大学外国语学院为例

当前，内蒙古地区的民族基础教育也由以往的蒙、汉双语教学逐步扩展为蒙、汉、英三语教学。而能否具备一支整体文化素质和专业水平较高的蒙古族英语教师队伍，则关系到能否顺利地、高质量地、全面地实施三语教学中的英语教学。故此，高等学校责无旁贷地担负起了培养从事民族基础与中等教育的蒙古族英语师资的历史重任。于是，对内蒙古地区高校师范类英语专业“蒙生班”的“零起点”英语教学研究也就显得越来越重要了。本文针对内蒙古地区高校“蒙授班”英语教学的特殊性，提出了自己的教学对策和模式。     

身势语在英语教学中的运用

在英语教学过程中,为交流信息、传递感情,教师在使用语言交际的同时,还会使用多种非语言交际手段,身势语则是非语言交际中表现力最强也是最丰富的一种,并且在交际中有着口语无法替代、只可意会难以言传的魅力。在英语教学活动中,教师能否正确运用身势语,对能否营造学习英语的浓郁文化氛围,能否激活学生的积极学习兴趣,能否潜移默化地影响学生注意力,都起着潜在的重要作用。身势语是英语教学中潜在的隐性力量,关系着英语教学能否有效进行。     

递阶双因素模型估计信用组合一致性风险

当信用组合内资产个数较少时，基于Gordy提出的粒度调节方法计算的组合风险量度VaR将严重被低估，从而高估一致性风险量度预期短缺ES。本文利用Taylor展开式改进粒度调节方法，提高估计ES的准确性；并且假设行业因素是宏观经济因素的线性函数，由此保证了组合不变性的条件，从而扩展单因素模型为递阶双因素模型，提高相关性估计准确性，解决了单因素模型高估经济资本的问题。模拟结果显示递阶双因素模型的优越性，特别是组合内资产规模较小时，改进的效果更明显。     

口译笔记的认知理据

口译笔记是影响口译质量的一个重要因素。文章从认知科学的角度出发分析了口译笔记的特点和规律,指出口译笔记的具体操作和激活扩散模型、图式理论、连通主义等许多认知领域的研究成果有密切的联系,其中尤其是吉尔的精力分配理论,对如何做口译笔记有很强的实践指导作用。     

From cultural knowledge to intercultural communicative competence: changing perspectives on the role of culture in foreign language teaching

Approaches to the concept of culture and teaching cultural competence in a foreign language classroom have been changing over the last decades. The paper summarises, compares, contrasts and evaluates four major approaches to teaching cultural competence in foreign language teaching, that is, knowledge-based approach, contrastive approach, Communicative Language Teaching and intercultural communicative competence approach.     

Claiming a Space for International Social Work: Voices From the Field

Despite the rise in interest in international social work, surprisingly little empirical evidence exists outlining the knowledge, values, and skills required of social workers to succeed in the global arena. This qualitative study conducted from the spring through winter months of 2013 involved 10 semi-structured interviews with experienced international social workers triangulated with a content analysis of 52 international job postings. Findings suggest that social work professional perspectives including eco-systemic thinking, social justice principles, strength-based analyses, and foundational skills, such as developing empowering person-centered relationships, exhibiting cultural humility, implementing participatory approaches to research and practice, and demonstrating reflexivity, are not always valued by international colleagues nor sought in job advertisements. Furthermore, upon graduation, MSW social workers may lack key areas of expertise expected of international workers such as program monitoring and evaluation, grant writing, policy development, and communicating with media and high-level officials. Ultimately, the invisibility of foundational social work skills and lack of other technical expertise may not only challenge social workers' competitiveness on the global market but also threaten their maintenance of a professional social work identity over time. The authors provide guidance for schools of social work and accrediting bodies to improve social workers' readiness for international work and strengthen their presence in the international arena.
