Technological adoption and use after mass market displacement: The case of the LP record

This paper investigates the reasons why some technologies, defying general expectations and the established models of technological change, may not disappear from the market after having been displaced from their once-dominant status. Our point of departure is that the established models of technological change are not suitable to explain this as they predominantly focus on technological dominance, giving attention to the technologies that display highest performance levels and gain greatest market share. And yet, technological landscapes are rife with technological designs that do not fulfil these conditions. Using the LP record as an empirical case, we propose that the central mechanism at play in the continuing market presence of once-dominant technologies is the recasting of their technological features from the functional-utilitarian to the aesthetic realm, with an additional element concerning communal interaction among users. The findings that emerge from our quantitative textual analysis of over 200,000 posts on a prominent online LP-related discussion forum (between 2002 and 2010) also suggest that the post-dominance technology adopters and users appear to share many key characteristics with the earliest adopters of new technologies, rather than with late-stage adopters which precede them.     

LP的企业文化建设及其当前面临的问题

精益生产(Lean Production,简称LP)作为当前最优的现代生产管理模式,其背后必然有相应的企业文化相匹配。但是我国现行企业管理体制、组织机构、员工角色等方面对这种文化的建立产生了一定的阻碍作用。因此,我国企业要建立起适应精益生产要求的企业文化,体制要进行适当的调整、改革与创新,思想观念要更新。     

对第三方物流服务供应商选择问题的研究

在结合我国国情及市场发展趋势的基础上。具体分析了第三方物流服务的优势，并从选择的原则及步骤等定性角度入手，阐述了如何实施对第三方物流服务供应商的选择；接着又从定量角度出发．详细讨论了如何在层次分析法的基础上，进一步应用线性规划法建立模型，以解决多源供应商的选择及优化组合的问题。最后通过举例分析，具体说明了集成物流服务供应商作为部分物流服务的需求方，应如何对功能型物流服务供应商进行选择。并以此证明了模型的有效性和实用性。

A Decision Model for Supplier Selection Considering Trust

A best selection of suppliers＇ combination can reduce a buyer＇s cost efficiently in SCM. Tt＇ust between suppliers and buyers influences the final choice. In this article a supplier selection model is established considering trust, using integrated analytic hierarchy process （AHP） and linear programming （LP）. This model is applied to supplier selection in Tianjin Electric Construction Company.     

Financial optimisation of forest-level harvest scheduling in Ireland – A case study

World-wide, forest managers have long recognised the benefits of using optimisation-based modelling techniques to improve decision-making. With no such systems in operation in Irish forestry, optimisation-based economic models were developed for harvest scheduling on a forest level within the context of a hierarchical approach. These new techniques were compared to those currently employed by Coillte Teoranta (the Irish Forestry Board). The development of the optimisation models involved the evaluation of: different management options strategies, optimisation techniques, model types and constraint strategies. Evaluation of the models was carried out in Clonbrock forest (294.8 ha), a typical Irish plantation forest, owned and managed by Coillte. The application of the selected model resulted in an increase in net present value (NPV) over the 5-year planning period of 14.2% compared to the NPV produced by Coillte's current process.

产业内集聚、垂直关联产业溢出与企业效率——基于广东省制造业企业微观面板数据

从微观企业层面入手,本文利用2005—2007年广东省制造业企业平衡面板数据集,研究了产业内集聚和垂直关联产业溢出对企业效率的影响。在研究中,为了消除TFP估计中存在的变量内生性问题,论文采用＂LP＂方法进行处理。实证发现,产业内集聚对企业效率有显著的正效应,垂直关联产业溢出也对企业效率有显著的促进作用,结论证实了地方化经济和城市化经济对中国经济增长的正向作用。
