科技期刊出版业务流程的案例研究

本文基于业务沆程再造理论、数字内容理论和开放存取的技术方法,针对两种典型的样本期刊,对出版业务流程进行了对比研究。案例研究发现,传统期刊的出版业务流程在成本、质量、服务、速度等方面存在严重的缺欠,而再造后的网络期刊出版节约了时间和资金,提高了质量,加强了互动的服务,提高了效率,实现了整个出版工作的协调一致,取得了戏剧性的效果。基于此,本文提出对科技期刊业务流程再造的思考。     

企业战略差异度会影响分析师盈余预测吗？

随着我国资本市场的发展,证券分析师的作用日益凸显,关于分析师盈余预测的研究一直是各界关注的重点。采用我国沪深两市A股上市公司2011—2015年分析师盈余预测数据,检验了企业战略差异度对分析师盈余预测精度和分析师跟踪偏好的影响。实证结果表明：（1）企业战略差异度越大,分析师盈余预测准确度越低;（2）企业战略差异度越大,分析师盈余预测分歧度越大;（3）企业战略差异度越大,分析师跟踪人数越少。进一步研究还发现：国有产权会削弱战略差异度对分析师盈余预测准确度和跟踪人数的不利影响。     

A context-based service matching approach towards functional reliability for industrial systems

ABSTRACT

As service-oriented computing is commonly used in industrial systems to deal with the continually changing business environment, matching processes with existing services becomes one of the most important phases in constructing, integrating and optimizing information systems. The precision of semantic service matching becomes a critical factor in ensuring the correctness of functionalities in system processes. However, the dependability of semantic service matching cannot be warranted in complex contexts. To improve semantic service matching for industrial systems, a context-based semantic service matching approach named ‘Process-Based service MatchMaker’(PBMM) is proposed in this paper. It selects the suitable services for the process from candidate services through taking the dependencies of related services process into consideration.     

The governance of sustainable business model innovation—An Ordonomic Approach

This paper develops an ordonomic approach to the governance of sustainable business model innovation (SBMI). We clarify the distinctive roles of optimization and governance for the management of sustainable value networks and develop a sustainability cube as a new management tool for the governance of SBMI. Our cube helps management to identify and overcome social dilemmas within value networks, i.e. to form and reform relevant business relationships, thus creating and tapping second-order win-win-win potentials. Furthermore, our cube encourages management to interpret negative externality problems as “missing markets”, i.e. as an entrepreneurial challenge and as a business opportunity to serve as yet unmet needs. Finally, our cube offers an avenue to develop and strengthen the specific management competencies that foster a successful governance of SBMI.

基于SUPER的证券信息公司服务模式选择

本文从理论与实证两个角度分析证券信息公司的服务模式选择.实证分析时,选取证券信息市场典型的19种业务类型为决策单元,建立评价指标体系,对5家有代表性的证券信息公司进行数据采集,采用SUPER模型、CCR模型和波达数处理方法,得出证券信息公司服务模式选择顺序为:内容传播、内容包装、内容精加工、咨询、平台和内容粗加工服务模式.最后,从企业资源的角度为现有或拟进入的同类型企业的服务模式选择给出建议.     

Might randomization in queue discipline be useful when waiting cost is a concave function of waiting time?

This paper suggests that introducing randomization in queue discipline might be welfare enhancing in certain queues for which the cost of waiting is a concave function of waiting time. Concavity can make increased variability in waiting times good not bad for aggregate customer welfare. Such concavity may occur if the costs of waiting asymptotically approach some maximum or if the customer incurs a fixed cost if there is any wait at all. As examples, cost might asymptotically approach a maximum for patients seeking organ transplants who will not live beyond a certain threshold time, and fixed costs could pertain for knowledge workers seeking a piece of information that is required to proceed with their current task, so any delay creates a “set up charge” associated with switching tasks.

运输制冷企业供应商的选择与评价

随着冷链品消费的增加,运输制冷企业有巨大的发展空间。中国运输制冷企业应积极开拓国内市场,通过有效的供应商评价体系对国内供应商进行选择。首先,对相关企业的采购部门进行访谈．了解运输制冷企业供应商选择的要求和标准,以及影响因素,建立供应商评价指标体系,利用AHP和DEA方法进行分析。然后以上海某运输制冷设备公司为例进行实证研究．对公司在欧洲、天津、上海三个供应商的相关信息。包括成拳、质量、产品柔性、供货灵活可靠、服务、技术能力等情况进行评价,最后择优作出选择。通过计算结果也证明了该评价体系的有效性和可行性。
