Dynamic business process modeling and verification for inter-organizational collaboration

To achieve an on-demand and dynamic composition model of inter-organizational business processes, a new approach for business process modeling and verification is introduced by using the pi-calculus theory. A new business process model which is multi-role, multi-dimensional, integrated and dynamic is proposed relying on inter-organizational collaboration. Compatible with the traditional linear sequence model, the new model is an M x N multi-dimensional mesh, and provides horizontal and vertical formal descriptions for the collaboration business process model. Finally, the pi-calculus theory is utilized to verify the deadlocks, livelocks and synchronization of the example models. The result shows that the proposed approach is efficient and applicable in inter-organizational business process modeling.

Do Relationships Matter in Export Performance Enhancement？ Evidences From Moroccan SMEs

This article addresses the concern of export performance among Moroccan SMEs through the paradigmatic lens of the resource based view （RBV） and international relationship marketing. Limited research exists on relational determinants of export performance, especially in developing countries. Furthermore, literature has been dominated during the last decade by the economic perspective. Yet, an increased attention has turned to the RBV as well as the relational perspective. Highlighting this gap, the study aims two objectives： First, to understand the scope and the nature of relational determinants, deemed as key resources, of export performance. Second, to examine which other internal and market factors are intervening as significant antecedents of the relational factors Drawing from a literature review outcomes and an in-depth interview endeavor conducted among 20 exporting firms＇ managers, a conceptual framework has been proposed. It＇s argued that exporting finns would reach great export performance by fostering successful cross-border inter-firm relationships. More specifically, the study highlight three main relational constructs, namely contractual governance, relational governance, and relationship performance. Linguistic abilities, attitude toward risk and export experience are suggested as managerial antecedents. While competitive intensity and market uncertainty are supposed to intervene as external antecedents Several hypotheses are suggested. The unit of analysis is a selected export venture. A further inquiry of the overall study is to offer hypotheses test throughout quantitative survey

Monitoring and Measuring Event Decision-Making Process Using Key Performance Indicators： Evidence From Italian Cruise Terminals

This paper investigates the control systems and coordination mechanisms applied in the relationships between cruise line companies and terminal concessionaires in the cruise events management when the ships are stopping on the quay. Using a case study methodology and focusing on the Italian context, this exploratory study, through a qualitative approach, interviewed two main cruise terminal concessionaires and indirectly observed events planned by cruise companies in sea ports selected for outlining the role of control systems, coordination, and knowledge sharing between the players in cruise events decision-making processes. The first results show that the cruise event management processes on ship berthing and on terminal are separated. The cruise companies don＇t involve terminal concessionaires in the event organization considering them only service suppliers Also, the concessionaires conceive the events planned in the cruise infrastructures as a business unit to optimize the space use, without any forms of coordination or control with cruise companies. Knowledge sharing, coordination, and control among the two players could support the planning, and management of ＂new cruise events＂ in which the visitors may be led from the infrastructure to the ships stopped on the quay. This study offers a set of key performance indicators to support the management, control, and coordination of each inter-organizational relationship identified. Managerial implications and suggestions for improving cruise events management have been provided.

Two in One： The Collaboration Between Science Foundation Lecturers in Imparting Academic Skills to Students

Learning challenges are more common in the 21 st century than many people believe; however, there are more efficient and better methods to develop academic learning skills for students. Identifying learning problems can help both students and lecturers to apply specific learning techniques and work together to be more productive in the process of teaching and learning. This study investigates the collaboration of science foundation lecturers in addressing the students＇ academic performance and challenges in their foundation modules at the University of Venda. The study is also aimed at finding out whether students can be able to apply their information technology （IT） skills in other modules and they make use of group work in projects into different foundation modules to enhance performance and develop academic learning skills. In this study, students were given projects in their respective modules （Foundation Biology and Foundation IT） and it was required to them to make use of their IT skills during the research report and also during the presentation of their project. These projects were done in groups wherein students undertook some mini researches. Their findings were then reported in writing and presentations were held. The Foundation English lecturer helped in assessing the use of the academic language used in writing and during oral presentations. The findings from these projects were that students＇ academic performance and skills improved and their specific knowledge in those modules also improved radically. It was found that group work plays a very imperative role in enhancing the students＇ performance and collaboration in various foundation modules.

竞争加剧和市场环境的快速变化使得制造业商业竞争模式从企业间的竞争转变为供应链间的竞争,而大数据分析能力对于供应链管理具有重要的作用,探寻大数据分析能力对供应链绩效产生影响的作用机理可以提高供应链竞争力。该文基于协同创新视角,引入环境动态性这一变量建立调节效应模型,探究了大数据分析能力对供应链协同创新和绩效之间深层次的作用机制,以制造业供应链上企业为研究对象通过问卷调查进行实证分析,结果表明:大数据分析能力(资源整合能力、深度分析能力、应用能力)对供应链绩效具有显著的正向影响,供应链协同创新在大数据分析能力各维度与供应链绩效之间起中介作用,环境动态性对深度分析能力与供应链协同创新的关系具有正向调节作用,但对资源整合能力、应用能力与供应链协同创新的调节作用不显著。

科创园区协同创新绩效影响因素组态研究

基于创新生态理论,从组态视角探讨科创园区协同创新绩效与其影响因素间的复杂因果关系,为丰富科创园区协同创新绩效的研究和科创园区的创新活动提供实践参考。首先从创新生态系统理论出发,以8家位于江苏省的国家级科创园区作为典型案例,运用扎根理论的编码技术和文本分析法,识别出影响科创园区协同创新绩效的关键因素;然后基于组态视角,进一步选取69家江苏科创园区,采用fsQCA方法,通过案例间的比较探索影响其协同创新绩效的条件组态。研究发现:(1)单个要素不构成科创园区高协同创新绩效的必要条件;(2)驱动科创园区高协同创新绩效有4种条件组态,体现了科创园区协同创新绩效的多重实现模式,具体为校-政二元驱动型、园区主导-政府支持型、政-校-园协同联动型和政府主导-园区运作型;(3)组态中部分资源的投入存在替代效应,例如,在一定条件下,高层次人才和经费资源的投入在实现高协同创新绩效的过程中具有相同效果。

社区“党领共治”绩效差异的类型学分析

在党的领导下构建多元共治的社区治理共同体,已然成为新时代国家基层治理体系的基础性结构安排和基层治理能力现代化建设的重要内容。在一致性的结构安排下,各地社区在实践中却形成了差异化的治理绩效。何种因素催生了“党领共治”的绩效差异是核心问题所在。基于协同治理理论,从地方政府制度设计能力和社区党组织领导力两个维度构建了“党领共治”绩效的分析框架:地方政府的制度设计提供了明晰的引导和规则约束,是“党领共治”的外部推力;社区党组织的领导力是链接治理资源、实现“党领共治”的内部驱动力。同时,基于制度和领导力的差异化组合,区分了“形式主义、内部驱动、外部指导、内外统合”四种“党领共治”模式,并通过案例比较发现其绩效差异。其中,形式主义“党领共治”的绩效表现最差,内部驱动和外部指导型的“党领共治”绩效表现居中,内外统合型“党领共治”绩效表现最好且具有稳定性。对新时代党建引领社区治理绩效差异的科学阐释既有助于增进知识积累,也能为地方政府制度的优化和社区党组织领导力的提升提供经验借鉴。

突发事件冲击下企业协同履责对再制造供应链绩效的影响

再制造是循环经济的高级形式,也是我国实现“双碳”目标的重要途径。再制造环境绩效的实现有赖于供应链社会责任水平。随着VUCA时代的到来,突发事件频发,给再制造供应链带来极大挑战。突发事件冲击下如何保障再制造供应链绩效,对于我国“双碳”目标的实现具有重要意义。基于文献研究及调查研究,构建研究假设和理论模型,并采用偏最小二乘结构方程模型,实证检验突发事件冲击下企业协同履责对再制造供应链绩效的影响,以及突发事件冲击与供应链文化对企业协同履责与供应链绩效关系的链式调节机制。研究发现:第一,企业协同履责对再制造供应链绩效具有显著的正向影响;第二,突发事件冲击正向调节企业协同履责与再制造供应链绩效的关系;第三,追求集体主义、关注长期规划、注重高权力对称性的供应链文化在企业协同履责与再制造供应链绩效的关系中起正向调节作用,在突发事件冲击调节企业协同履责与再制造供应链绩效关系的过程中起部分中介作用。因此,为有效应对突发事件冲击,一方面,再制造供应链企业应认识到协同履责对供应链绩效的正面作用,在日常运营中主动践行协同履责,积极开展社会责任信息共享,并积极进行联合规划,建立激励联盟;另一方面,应主动调和不同企业文化之间的差异,营造积极和谐的供应链文化氛围,构建高权力对称性、高集体主义、长期导向的供应链文化。

什么类型的机构合作会产生更高的学术影响力?--以自然语言处理领域为例

研究特定领域中机构合作类型与学术影响力之间的关系,能深入了解不同合作类型所产生的学术影响力差异,以识别出哪种类型的合作可能更具生产力或效率。文章以自然语言处理(NLP)领域为例探究机构合作类型与学术影响力之间的关系。通过与工业界进行合作,可以将学术界的研究成果转化为实际应用,但不同合作模式对合作效果的影响有所不同,因此文章研究不同类型的机构合作与学术影响力之间的关系,从而帮助机构更好地规划合作策略,提高合作效果。首先,将机构分为学术界机构和工业界机构;然后,将合作类型分为学术界机构间合作、学术界机构内合作、学术界与工业界机构间合作、工业界机构间合作和工业界机构内合作;最后,从谷歌学术获取5种合作类型发表的论文被引频次信息,同时定义高被引论文,采用这两个指标衡量学术影响力,并将论文归属到NLP领域不同任务,发现学术界与工业界的机构间合作往往能产生更大的学术影响力,且在不同任务中学术影响力最高的机构合作类型存在差异。
