大学生就业决定因素分析——基于多层模型的方法

本文利用山东2007届高校毕业生就业调查数据,建立多层交叉随机效应模型,检验了个体、专业和学校等多层变量对大学生就业的影响。结果发现,初次就业概率在学校和专业之间存在显著差异,且学校因素对就业的作用大于专业,但学校与专业对就业的交互作用不显著。就业能力以及与专业相关的实习经历对就业具有显著的正向作用。因此,大学生就业政策的重点是提高教育质量和突出专业特色,提升就业能力,完善就业导向的实习指导和服务。     

电子货币对泰勒规则影响的理论和实证研究——以中国为例的分析

文章通过一个理论模型分析了电子货币的产生对于泰勒规则的影响作用,进而以中国为例,使用1988至2007年的数据分别对电子货币产生前后两段时期的泰勒规则进行了拟合。研究发现,泰勒规则与我国货币政策具有较强的一致性,并且电子货币进入成熟阶段后泰勒规则的有效性比电子货币产生之前的阶段大为降低。结论认为,中国进入电子货币时代后的最优货币政策规则应当是以泰勒规则为基础,以多种中介目标为辅助性操作工具的政策规则。     

试论修辞叙事学的修辞效果

对修辞叙事学修辞效果的研究是修辞叙事学研究的主要内容。效果研究是一个开放的研究领域,作者通过文本在读者那里达到的效果是一个复杂的存在,因此,这种研究带有某种尝试性。对叙事修辞效果的研究首先是对产生效果的基础进行分析,探讨影响效果的诸种因素,然后,对叙事修辞的各种效果再进行具体的分析。     

Selecting significant effects in factorial designs: Lenth's method versus using negligible interactions

Among the many analytical techniques that have been published to analyze the significance of the effects in the absence of replications, two have emerged as the most widely used in text books as well as statistical software packages: The Lenth's method and the estimation of the variance of the effects from the values of those considered negligible. This article shows that neither is better than the other in all cases, and by analyzing the results obtained in a wide variety of situations it provides guidelines on when it is preferable to use one or the other technique.     

真实固定效应空间随机前沿模型的贝叶斯估计

忽略个体效应和空间效应会严重干扰效率测算,其中忽略个体效应使得技术无效率项发生偏移,忽略空间相关性导致估计量有偏且不一致。本文基于真实固定效应随机前沿模型（引入了个体效应）,引入因变量和双边误差项的空间滞后项,构建了适用性更佳的真实固定效应空间随机前沿模型。对模型进行组内变化以消除额外参数,使用贝叶斯方法（需推导未知参数的后验分布并执行MCMC抽样）估计参数和技术效率。该方法真正克服了额外参数问题,比同类方法直观、简便。数值模拟结果表明,本文方法对参数、个体截距项及技术无效率项的估计精度均较高,且增加样本容量,估计精度变优。     

高层管理团队内部社会资本、团队冲突和决策效果的关系——研究综述与理论分析框架

反映在结构因素、关系因素和认知因素三个维度上的高管团队内部社会资本为决策信息的交换和共享提供了机会、意愿和能力,有利于团队内部形成建设性的冲突模式,促进决策效果的提高.本文以团队冲突为中介变量,建立了高管团队内部社会资本与决策效果的关系的理论框架,提出了研究命题,并对企业高管团队内部社会资本的培育提出建议.     

低生育率水平下人口发展的经济后果分析

本文分析了低生育率水平下人口发展对未来我国经济发展的积极影响 ,同时指出它是一把双刃剑 ,同样也有不利于经济发展的后果。为了既充分发挥低生育水平的积极作用 ,又逐步消除或缓解其不良后果 ,一方面要适时地调整现行生育政策 ,选择适当的总和生育率水平 ,另一方面要构建相应的政策支持体系予以支撑。     

人口网络信息传播的策略探析——以中国人口网为例

通过考察中国人口网的信息传播现状,认为其信息传播多为自上而下的宣传,少平等温和的互动,没有发挥网媒的优势,传播方式还处于传统媒体信息网络化阶段,缺乏有效的信息传播手段和技巧。为此,运用传播学理论探析增强人口计生信息传播效果的手段和途径,认为在人口计生宣传中有效设置议程,满足受众的信息需求,并注意新闻信息的涵化,有助于正确引导计生舆论,提升计生政策的宣传效果。     

Employee absence,age and tenure: A study of nonlinear effects and trivariate models

Multiple regression techniques were used to explore the nature of the relationships between age, tenure and absence in 2417 British local government workers drawn from three work groups. The data were collected from organizational records and included measures of both non-certified absence and medically certified absence. Linear and curvilinear associations among age, tenure and absence were examined. The possible moderating or mediating role of tenure in the relationship between age and absence was subsequently analysed. The data revealed linear relationships between age and absence that were negative for non-certified absence and positive for certified absence. In contrast, curvilinear relationships were found between tenure and absence that were U-shaped for noncertified absence and inverse U-shaped for certified absence. Tenure was found to moderate but not to mediate the relationship between age and absence. The implications of the results are discussed in the context of the changing age and career paths of the workforce, and of methodological issues in absence research.     

Distribution Channel Strategies for a Manufacturer with Complementary Products

In this article, we consider distribution channel strategies for an incumbent manufacturer who produces two complementary products and must determine whether or not to have another company to sell its products. We identify factors that affect the manufacturer's motivation to use dual‐channel distribution. Our results show that both complementarity between complements and product substitutability between firms influence the manufacturer's channel strategy. We find that if the potential entrant does not produce the complement of the primary product, a higher complementary effect for the complement will weaken the motivation of the incumbent to add an indirect channel. We also find that the incumbent has a stronger incentive to add the indirect channel when a product's substitutability is high. Furthermore, we show that when the two channels have the same pricing power, the incumbent has a stronger incentive to sell through the indirect channel in a higher pricing power environment.
