教师职业素养新论

国家于2010年新出台的《国家中长期教育改革和发展规划纲要(2010——2020年)》(以下简称《教育规划纲要》),使教师的职业素养再度引起公众的关注。文章将其归结为"敦品"、"业精"、"敬业"六个字,并从这三个方面入手谈教师的职业素养。     

Environmental practices and firm performance in emerging markets: the mediating role of product quality

Environmental practices have not received as much research attention in emerging market contexts as traditional topics like quality. However, the importance of environmental practices for a firm’s production strategy has been increasing at an unprecedented level across the globe. Our research objective is, therefore, to investigate the interplay between environmental practices and quality in the pursuit of firm performance. Relying on 492 responses from Turkish manufacturers to test our hypotheses, we show that environmental practices directly improve the quality of products over and above the effect of quality management practices in emerging markets. Product quality, in turn, is important for increasing firm performance, acting as a mediator for the positive effects of environmental practices on performance. Thus, we reveal that product quality functions as an instrumental conduit between environmental practices and firm performance in emerging markets like Turkey where stakeholder pressures are weak, and regulations are often not properly enforced.     

基于产品生命周期的多阶段剩余收益项目决策模型

剩余收益模型（Residual Income Model,RIM）是评估公司权益价值的经典模型,特别地,奥尔森系列剩余收益模型由于可以利用历史财务与会计数据而得到广泛运用。本文在一般剩余收益模型的基础上,运用规范研究、逻辑推理等方法,基于产品生命周期理论,即项目处于产品生命周期的不同阶段时,其净资产收益率不同,在增长期的净资产收益率持续上升,衰退期的净资产收益率持续下降,而成熟期的净资产收益率则围绕行业平均水平波动,从理论上就项目投资价值的评估构建了多阶段剩余收益项目决策模型,并就所构建的多阶段剩余收益项目决策模型进行参数赋值分析。研究结果表明该新构建的决策模型具有较好的理论和运用价值,可以作为一种有效的项目投资决策模型。本文的研究一是拓展了剩余收益模型的应用,从主要用于对公司权益价值的估值拓展至对项目投资决策的评估;二是有利于寻求项目投资决策的价值最大化。     

基于个性化需求的产品竞争供应链结构选择

基于"制销分离"与"定制一体"两种结构选择,构建个性化产品供应链处于非竞争与竞争环境下的博弈模型,在引入一个实际案例的基础上,运用算例仿真比较分析两种运营模式下的供应链运作策略和盈利差异。结果显示：与制销分离结构相比,个性化产品供应链选择定制一体结构,有利于匹配产品个性化制造、提升产品个性化水平和市场需求、增加供应链的期望收益;个性化产品供应链选择制销分离结构时,适度的批发价格激励能够提升产品个性化水平、更好满足消费者个性化需求、改善供应链的运营绩效,分销商适度让利加大批发价格激励力度可显著促进产品个性化制造互动、提升产品个性化水平;竞争将消减个性化产品供应链的运营绩效,但选择定制一体结构可显著提升竞争力。     

考虑重复购买因素的品牌竞争对新产品扩散的影响研究——基于小世界网络的仿真环境

在对品牌竞争影响要素分析的基础上,考虑重复购买在新产品扩散过程中的调节效应,构建以消费者微观采纳机制为核心的新产品扩散的阈值模型,在小世界网络仿真情境下,运用多智能仿真方法对品牌竞争与新产品扩散之间的影响关系进行分析,研究结果表明：转换成本对新产品扩散的速度和深度的影响存在一定的"条件区域",在该区域之外两者不存在显著的影响关系;进入时间与两种竞争性品牌的扩散速度存在一致的负向的影响关系,而对两种竞争性品牌的扩散深度的影响方向则相反;在此过程中,重复购买系数起着一定的调节效应,会在一定程度上放大或缩小转换成本及进入时间对新产品扩散的影响效应。通过本文的研究,不仅可以进一步丰富和完善竞争性产品创新扩散的相关理论,也可以为企业的新产品推广实践提供决策支持。     

Development of sustainable platform for modular product family: a case study

Abstract

Defining product platform architecture is a critical issue to design and develop product variants. Different factors are highly dependent on the architecture type, such as number of variants, to measure modularity level, component commonality, market demand, etc. It is directly related to manage product portfolios and setting up business plan of a company. Before defining a product platform, whether it is modular or integral product designers need to follow specific design guidelines and checklists. This research mainly focuses on to define the platform architecture as well as provides necessary design guidelines and checklists for the product designers. It also highlights an example product of a case company with the objective to clarify/validate the proposed product design approach. In conclusion, this paper outlines the findings from this research and proposed some critical questions need to be answered within the scope of future research potentials.     

Decision model for product rollover in manufacturing operations

The purpose of this study is to investigate critical decisions when planning for product rollover at a manufacturing company, and how to organise these decisions. A literature review and a case study are used to develop a decision model. The findings indicate that product rollover can be organised in a five-phase decision model. The research quality is strengthened by a structured literature review, but it can be argued that more empirical research is needed for validation. For researchers, this paper contributes with the identification of critical decisions and a model for product rollover. For practitioners, the study highlights the need to acknowledge the importance of product rollover and its role as a competitive weapon. In earlier studies, product rollover has mainly been investigated from a market perspective, so that this study contributes by investigating the issue from a manufacturing perspective.     

社会网络、 先前经验与创业风险识别

无法识别创业风险是导致创业失败的主要原因之一,如何有效识别并管理创业风险是新创企业健康成长的关键.社会网络能够弥补创业者在识别风险过程中的信息劣势,但既有研究极少探索社会网络是否以及如何影响创业风险识别.为弥补这个研究空白,文章利用信息处理理论为研究框架,构建了创业风险识别模型.具体而言,结构洞和网络强度有利于创业者获取更多、高质量与风险相关的信息,进而识别更多的创业风险;获取信息的数量在网络强度与创业风险识别关系之间发挥完全中介作用;创业者的先前经验正向影响创业风险识别,并对结构洞与获取信息的数量之间关系起调节作用.文章讨论了研究结果的理论贡献与实践启发.     

The social security number: A small device underpinning big systems

The possession and use of a personal social security number helps to structure people's daily lives. However, despite its fundamental normative importance, the social security number remains a little‐known entity. Increasingly universal and yet diverse in form, it is a legal and technical norm which is as much a mechanism for surveillance and monitoring as it is a necessary instrument for giving effect to social rights. Analysis of this constituent element of social security systems permits as assessment of some of the technical difficulties presented by the ever‐increasing movement of people and data. Overcoming these technical difficulties should permit to envisage a first technical step towards realizing a universal and global social security system.     

“三鹿奶粉事件”中生鲜乳收购站的产品责任分析

将初级农产品作为产品责任法中的"产品",其生产者认定为产品责任承担主体,加大对消费者的保护力度,是世界产品责任立法的发展趋势.我国应将生鲜乳等初级农产品纳入产品责任的"产品"范围之内,让缺陷初级农产品生产者对受损害的消费者直接承担产品责任,以有效遏制和防范产品质量安全事件的频发.在 "三鹿奶粉事件"中,缺陷生鲜乳的生产者--收购站应承担产品责任.在产品责任构成要件方面,应该适当降低消费者对因果关系的证明标准.
