高职院校新生数学基础现状调查及对策分析——以北京劳动保障职业学院为个案

数学课是高职院校各专业必修的重要基础课和工具课,但由于种种原因,高职学生的数学基础总体水平不高,而且学生之间差距较大、参差不齐。在教学中针对数学不同水准的学生实行分层授课,实践证明教学效果显著提升。     

The Progress, Challenges and Countermeasures of the Labor Contract Law

In recent years, as the process of industrialization, urbanization, and economic restructuring speeded up, the enterprises＇ system reform deepens, the diversification of business forms and labor relations increased, there have been some new situations and problems of the labor relations. The legitimate rights and interests of laborers have been violated every now and then in some regions, and even very serious in particular industries. This is shown in the following areas： （1） Labor disputes arise when the legitimate rights and interests of laborers are not effectively protected, and the rate of labor contract signing is low.     

经济型轿车市场受制的原因分析

随着改革开放的深入和人民生活水平的提高，私人购车已成为带动我国汽车市场消费的主流，轿车市场的主导地位也逐步由公款消费向个人消费转变。然而，与频频传来的汽车降价信息以及此此起彼伏、红红火火的车文化展示相比，汽车销售市场仍显得雷声大点小，汽车工业的发展还是不能迈开大步。探究其受制的主要原因，笔者认为有以下三点。     

金融安全视角下的股市平准基金探析

通过平准基金的方式来平抑股价波动理论界历来存有争议。然而,宏观环境的变化、资本市场自身的体制机制性缺陷,将进一步增加我国金融体系的不确定性,强化金融内在的脆弱性,从资本市场的渠道对我国金融安全构成潜在的威胁和挑战。作为现代市场经济的核心,金融的稳定与安全高于一切,金融安全比市场化规则更重要。因此,规划设立股市平准基金,建立资本市场危机干预机制符合国家金融安全这一战略利益。当然,对于平准基金的管理、运作、风险控制和信息披露等方面应该制订一系列严格的制度规范,以控制基金自身的风险,保证基金的运行效率。     

陕西省农村中小学体育师资队伍现状调查

笔者针对陕西省农村中小学体育师资队伍现状进行了调查研究,结果表明:陕西农村中小学专职体育教师数量不足,教师学历结构偏低,年龄结构有待于优化,体育教师工作量相对较大,随着教师待遇的提高师资流失情况有所好转。并在此基础上提出加快陕西农村中小学体育师资队伍建设的对策。     

State ownership, firm size, and Chinese firms’ entry mode choices

Based on the strategy tripod perspective, this study intends to examine the independent and joint effects of state ownership and firm size on Chinese firms’ choices between greenfield and acquisition, and between full and partial ownership. Using secondary data of a sample of 150 firms with 473 entries, we find that state ownership and firm size independently and jointly have impacts on entry mode choices. Our findings provide some support to the strategy tripod perspective, which treats institutions as independent variables and considers strategic choices as the outcome of the interactions between institutions and organizations.     

基于单井效益评价的油田效益配产方法研究

油田优化配产是指油田企业对下属采油单位的产量、成本等进行配置,从而实现指标分解和效益最大。本文提出以单井效益评价数据为基础,在油田内部打破采油单位界限,以采油井为单元,对油田所辖的全部单井采用统一平台进行优化排序,分别以效益最大、成本最低、盈亏平衡为目标,建立配产优化模型,计算出油田公司的效益产量,再按照效益最大、成本最低的效益油井所属采油单位进行分配,从而实现油田公司的效益配产。实际应用表明,以单井效益评价为基础的油田效益配产理论和方法切实可行,为油田配产提供了新的思路,可以实现从能力配产到效益配产的转变,使油田达到最佳生产规模。     

关于金融创新影响货币需求的数值分析

利率行为反复无常的情况下,几乎无法用解析方式进行论述,所以在本文中将用数值方式更详细地研究这一模型中的货币需求问题。 一、计算均衡动态 为了从数量上解答这个模型,有必要为金融专门变量f(·)指定一功能形式并将相应数值分配到参数β、δ和ε。在下面讨论的所有例子中,f(·)被限定在:     

Examining the Third‐Person Effect of Baseline Omission in Numerical Comparison: The Role of Consumer Persuasion Knowledge

Marketers often use numerical comparisons in promotional claims to signal superior product offerings. A potentially misleading practice involves omitting the reference point deliberately in order to make the focal claim more appealing—a persuasion tactic referred to as “baseline omission” in the present research. In two experiments, this research demonstrates that consumers tend to perceive this tactic as more effective on others than on themselves. The self‐others difference is more salient among consumers with more persuasion knowledge. Consumers’ concerns about its effectiveness on themselves, rather than on others, better predict their supportiveness to regulate the use of baseline omission.     

国际贸易与劳动力市场:研究述评

近三十年来,国际贸易迅速发展,同时各国劳动力市场保持着一种动态变化,国际贸易对劳动力市场的影响不断加深.在这一背景下,国际经济学和劳动经济学领域的学者对国际贸易与劳动力市场的关系进行了大量的理论与经验研究,相关研究主要集中在三个方面:国际贸易对各国工资的影响、国际贸易对各国就业的效应以及国际贸易对劳动力需求弹性的影响.本文将从上述三个方面对相关研究进行回顾.
