Whose Heartland?: The politics of place in a rural–urban interface

This article advances a conceptualization of the rural–urban interface that is centred on a historically and spatially informed politics of place situated within local–global connections. The research is a case study of an inter-municipal development plan called Alberta's Industrial Heartland. Located near the City of Edmonton, in Alberta, Canada, the study area has been characterized by tremendous social, cultural, and economic shifts over the past century, from agriculture, to country residential in-migration, to intensive industrial development in response to the increasing importance of Alberta on the global energy market. A series of interviews conducted with residents, political officials, and other stakeholders documents how parallel, yet contested definitions of the ‘Heartland’ underpinned a ‘politics of place’ over land use change at the rural–urban interface.     

确保从研究到开发界面的有效管理 --R&D个体的知识转移管理

在技术密集型公司中一个重要的问题是构建"无隔层创新流程"(seamlessinnovationprocesses)."这里无发明"(not-invented-here,NIH)综合症和其它的障碍严重影响着研究和开发之间知识和技术的有效转移.由于存在着保守型结构、过时的转移设备以及下游职能定位模糊等原因,知识转移经常失败.从研究到开发产生障碍的原因主要有以下几方面:职能分割、地理位置、专业偏好和文化背景等.首先,我们在25家公司做了100多次的半结构性访谈;然后,我们在技术密集型产业做深入的案例研究.改进从研究到开发的界面总是围绕着R&D个体展开.我们通过对ABB、Hitachi、IBM、Kao、Unisys以及xerox等公司的案例分析,得出了一些成功的实践经验.我们得出这样的结论:从研究到开发界面的有效管理通过对管理R&D个体的知识转移获得.     

社会运行规范化与西北民族社会的和谐

用“层间状态”概念对社会运行状态作出简单的补正是有必要的,更为符合我国社会转型的特定话语背景。 社会运行规范化的基本要求至少应该包括以下几个方面:(1)社会运行的安全;(2)社会运行的可持续;(3)社会运 行的和谐。在急剧分化的客观情境下,西北地区民族社会的和谐就是要创设和谐共生的民族关系,就要求人们能够 不断挖掘隐藏干心中的道德性资源,不断地孕育人道主义的成果。     

基于CAN总线的一体化氧化沟DCS系统方案

针对一体化氧化沟生物处理系统控制问题,给出一种实用、基于ＣＡＮ总线的现场控制器与工业ＰＣ（ＩＰＣ）组成污水处理分布控制（ＤＣＳ）系统实现方案。由于该方案采用的现场控制器具有多主结构、实时能力和高可靠性通信,而集中监控的ＩＰＣ资源丰富,故整个ＤＣＳ系统开放性、实时性、可靠性和操作性良好。

How Costs and Heterogeneous Consumer Price Sensitivity Interact with Add‐On Pricing

Firms often cite cost savings as a reason why they charge separately for add‐ons. Firms also often face situations where consumers' price sensitivity is correlated with their valuation of add‐ons. While cost savings may directly translate into profit gains in some scenarios, this study examines the strategic implications of add‐on pricing and is the first to suggest that cost savings from add‐on pricing may in fact result in profit loss for firms when consumers are heterogeneous in price sensitivity. This is because add‐on pricing can trigger a revenue loss that exceeds any cost savings, thus leading to a negative net profit change for competing firms. Even if firms have the capability to pre‐commit to not adopting add‐on pricing, we show that competing firms can be locked in a prisoner's dilemma where all choose to adopt add‐on pricing and lose profits (as compared to none adopting add‐on pricing). We further show the possibility that the greater the cost of providing the add‐on (and the greater the cost savings generated from add‐on pricing), the worse this profit loss gets.     

Distributed Development and Product Line Decisions

Distributed product development is becoming increasingly prevalent in a number of industries. We study how the global distribution of product development impacts the profit‐maximizing product line that a firm offers. Specifically, we formulate a model to understand the linkage between cost arbitrage as a driver of distributed development and consequent market implications such as customer perceived quality loss to remotely developed products. Analysis of the model reveals that a firm should expand the product line for a development‐intensive good only at intermediate values of cost advantage and quality loss. We modify the base model to include development capacity constraints as a driver of distributed development and find that the results are robust to this change. Our analysis affirms the need for product managers to incorporate the implications of distributed development in making their product line design decision.
