注水泵机组磨损可靠性分析与评定

通过对注水泵机组磨损数据的统计处理,可得到寿命统计分布规律,并把握其可靠性数字特征,从而确定其可靠性指标;通过对不同机组磨损数据子样总体方差的显著性检验,可推断其总体寿命的稳定程度,并通过其子样总体均值的差异性检验,判断相互间磨损差异;通过对各台机组的趋势检验,得到各台机组的磨损趋势变化。这些对油田现场把握机组运行状况、合理安排检修,指导维修以及施工的经济性核算等环节有科学指导作用。

谈油田产品质量监督检验工作的管理

产品质量监督工作的基础是产品质量监督检验,加强产品质量监督检验工作的管理,是搞好产品质量监督工作的关键。笔者认为应从以下几个方面做好产品质量监督检验的管理工作。 质检机构的建设 开展产品质量监督检验工作,一方面要充分利用油田原有科研、试验机构,积极组织符合一定条件的科研和试验机构开展计量认证;另一方面对挂靠在油田的国家级、总公司级、省级、市级的质检机构进行充分利用,发挥它们的作用。应根据油田质量监督工作的需要将二者有机地结合起来,组建油田质量监督检验中心,共同承担油田产品质量监督检验任务。

提高物资检验准确率缩小入库物资检验与监督检验差距

近年来．为了确保油田物资质量．油田在监督检验方面的力度不断加大．这对于规范物资供应市场．保证物资质量方面确实发挥了重要作用．但随之也出现了监督检验与入库检验不一致的情况。由于两种检验方式、性质不同造成了差异。特别是化工类产品．由于其易变化的特殊性．在每次的监督抽样中最容易出现问题．对于入库的一批物资来讲．对其检验质量水平要通过许多环节来保证．例如取样过程、样品管理、仪器设备、实验水平等。作为入库检验来说．首先必须提高“物资检验准确率”．注意抓好物资抽样及检验的各个环节．才能有效缩小入库物资检验与监督检验差距。

稠油油田生产经营特性及产量与成本相关关系分析

稠油油田流体性质特殊,开采工艺复杂,成本高,开发后期成本增速加快。通过构建稠油油田产量—成本的回归分析模型,经数据抽样,测算其相关系数,进而检验了稠油油田产量—成本之间的内在逻辑关系。稠油油田的产量与成本之间呈非线性关系,稠油油田的成本结构中既含有固定成本又包括变动成本,新井产量、老井自然产量与老井措施产量所对应的单位操作成本逐次升高;老井措施成本占油田生产成本的比重较大,是今后加强管控的主要方向。通过产量—成本相关关系分析,掌握稠油油田在不同开发阶段的生产经营规律,有助于了解在油田现有生产能力下产量规模所对应的成本水平,从而合理确定配产规模与产量结构,提升开发效益。     

Number of sellers,average prices,and price dispersion

A variety of models provide differing predictions regarding the effect of an increase in the number of competitors in a market (seller density) on prices and price dispersion. We review different approaches to generating equilibrium price dispersion and then empirically estimate the relationship between seller density, average product price and price dispersion in the retail gasoline industry using four unique gasoline price data sets. Controlling for station-level characteristics, we find that an increase in station density consistently decreases both price levels and price dispersion across four geographical areas.

From Which Source Do Small Firms Derive Their Innovative Inputs? Some Evidence from Italian Industry

This paper relies upon the hypothesis that the “knowledge production function” – defined in the geographical sense – is characterized by coefficient estimates which vary with firm size. In particular, large firms depend for their innovative output on direct and indirect R&D inputs, whereas small firms more extensively exploit the spillovers from research activities carried out by universities and by other firms. This hypothesis is tested against two different sets of data: the first based on patent statistics and dealing with 20 Italian regions over the period 1978–86; the second consisting of a selected number of product innovations identified by a literature-based counting procedure and dealing with 46 Italian provinces in year 1989. The results of regression analysis support the hypothesis that firms belonging to different size classes resort to different sources for the knowledge relevant to their innovative output. In particular, industry R&D prove to play a relatively more important function than do spillovers from university research in generating innovative output in large firms, whereas the opposite is true in the case of small firms.

The Conditions Promoting Compromise in the Workplace

A previous article developed a framework to understand workplace co‐operation. We now elaborate on the key structuring conditions (technology, product markets and institutional regulation) generating different patterns and illustrate from field research how these different workplace regimes develop. Conditions generating positive and sustainable outcomes for both capital and labour are feasible but rare; stronger ‘beneficial constraints’ are needed if they are to be made more frequent. This article provides an alternative to current interpretations of labour–management co‐operation in the industrial relations literature.     

Licensing Foreign Technology and the Moderating Role of Local R&D Collaboration: Extending the Relational View

The relational resource‐based view posits that performance differences among firms can be explained not only by the possession of internal resources but also by maintaining and developing relationships with external partners. However, studies in the extant literature usually address the separated roles of various external relationships of focal firms, but the literature has not addressed how relationships with different sets of knowledge partners are related to each other and influence focal firms' performance. Therefore, to fill this research gap, this study focuses on how technological resources acquired from one set of partners (licensing foreign technologies) may generate subsequent internal and relational rents in terms of technological innovation in the context of collaboration with an entirely different set of knowledge partners (local R&D partners). Specifically, we propose that local R&D collaborations need to be large in scale and broad in scope. The empirics are based on the analysis of a sample of 160 high‐tech Chinese firms observed from 2000 to 2011. Consistent with our predictions, our findings contribute to extending the relational view by addressing the relations among the relationships of focal firms.     

Relationships and networks as examined in Industrial Marketing Management

The importance of the study of relationships and networks within business-to-business marketing is clear from the numerous articles written over the years that aim to give us greater insight into these two concepts. This paper reviews six of these articles. What sets these six apart from others is that they are the most highly cited articles on relationships and networks published in Industrial Marketing Management between 1995 and 2004. We examine each of these articles in terms of their scholarly impact and identify what researchers have learnt from these highly cited papers. Our conclusions show some interesting similarities that we feel has led to these articles being so highly cited. We conclude that the key to citation success is the identification of new research avenues. In addition, the chances of writing excellent papers seems to be improved when collaborating with others, rather than writing alone. By introducing new ideas these authors have not only been successful in their own work, but have given others the platforms to build on, thereby generating much more research in this area.     

Organisational culture and decision making: a case of consensus management

Abstract
This paper explores how a state-of-the-art concept, organization culture, shapes decision making and consensus generating strategies used in the successful management of product development activities in high technology companies. Engineering development groups interact with many individuals and groups on a wide variety of very comples engineering, manufacturing, marketing and business issues Much uncertainty exists around these issues because information that would allow for a decision to be made is often unknow or unknowable. Trade-offs are made continually resulting in a high degree of interdependence among development groups and others with whom they interact. Achieving a balance between controlling development activities on the on hand, and encouraging creativity and initiative on the other, is a complicated process.
this paper illustrates the role of organizational culture in product development using case material from a very successful US high case material from a very successful US high technology company. 'Consensus management', a major cultural theme at 'DW Enterprises', is a decision making style that involves everyone in the decision making process who might have relevant input. A cultural analysis reveals that the engineers developed specific techniques for generating consensus, and that these related as much to control over participation in product development as to decision making.
