在线品牌社区成员持续参与行为形成的动机演变机制研究

运用扎根理论,选择小米手机社区持续参与成员作为深度访谈对象,旨在研究社区成员持续参与行为形成的动机演变机制.研究结果表明,社区成员持续参与行为的形成是社区成员的参与动机在外部情境因素影响以及个人心理需要满足下不断内化的结果.具体表现为:初始参与阶段以外在调节的外部动机为主,包括信息动机和工具性动机;随后,参照群体、面子观以及关键事件促进了动机的内摄调节,初始动机驱动作用减弱,活动回报动机、社交动机、社会增强动机以及利他动机成为社区成员参与和贡献的主要驱动力;最后,社区成员能力需要和关系需要的满足促进成员对品牌、个人和社区产生依恋,持续参与行为得以形成和维持.     

国有企业CEO注意力对产品创新影响的研究

在探讨了CEO注意力、产品创新表现与企业绩效之间的关系的基础上,构建了有关理论模型,并通过问卷收集的方法对国有企业CEO进行了调研。研究结果表明,国有企业CEO对于外部的注意力普遍高于其对内部的注意力;外部注意力对于产品创新的技术表现和市场表现均有积极影响,内部注意力仅与产品创新的技术表现正向相关;产品创新的技术表现对于企业的财务绩效和非财务绩效均有积极影响,仅市场表现对企业非财务绩效有积极影响。     

Cloud manufacturing system for sheet metal processing

Abstract

Cloud computing is changing the way industries and enterprises run their businesses. Cloud manufacturing is emerging as an approach to transform the traditional manufacturing business model, while helping the manufacturer to align production efficiency with its business strategy, and creating intelligent factory networks that enable collaboration across the whole enterprise. Many production planning and control (PPC) problems are essentially optimisation problems, where the objective is to develop a plan that meets the demand at minimum cost or maximum profit. Because the underlying optimisation problem will vary in the different business and operation phases, it is important to think about optimisation in a dynamic mechanism and in a number of interlinked sub-problems at the same time. Cloud manufacturing has the potential to offer decision support as a service and medium of communication in PPC. To solve these problems and produce collaboration across the supply chain, this paper provides an overview of the state of the art in cloud manufacturing and presents a model of cloud-based production planning and production system for sheet metal processing.     

Bounds on the domination number of a digraph

A vertex subset S of a digraph D is called a dominating set of D if every vertex not in S is adjacent from at least one vertex in S. The domination number of D, denoted by \(\gamma (D)\), is the minimum cardinality of a dominating set of D. The Slater number \(s\ell (D)\) is the smallest integer t such that t added to the sum of the first t terms of the non-increasing out-degree sequence of D is at least as large as the order of D. For any digraph D of order n with maximum out-degree \(\Delta ^+\), it is known that \(\gamma (D)\ge \lceil n/(\Delta ^++1)\rceil \). We show that \(\gamma (D)\ge s\ell (D)\ge \lceil n/(\Delta ^++1)\rceil \) and the difference between \(s\ell (D)\) and \(\lceil n/(\Delta ^++1)\rceil \) can be arbitrarily large. In particular, for an oriented tree T of order n with \(n_0\) vertices of out-degree 0, we show that \((n-n_0+1)/2\le s\ell (T)\le \gamma (T)\le 2s\ell (T)-1\) and moreover, each value between the lower bound \(s\ell (T)\) and the upper bound \(2s\ell (T)-1\) is attainable by \(\gamma (T)\) for some oriented trees. Further, we characterize the oriented trees T for which \(s\ell (T)=(n-n_0+1)/2\) hold and show that the difference between \(s\ell (T)\) and \((n-n_0+1)/2\) can be arbitrarily large. Some other elementary properties involving the Slater number are also presented.     

Is Tattooing a Risk Factor for Adolescents’ Criminal Behavior? Empirical Evidence from an Administrative Data Set of Juvenile Detainees in Taiwan

Juvenile crime affects not only the victims of the crime but also the delinquents’ future. How to prevent adolescent criminal behavior has become an important public policy issue. This study contributes to this interesting issue by examining the relationship between tattooing and adolescents’ criminal behavior. In particular, this study investigates whether or not having a tattoo/tattoos is connected to the incidence of various criminal activities, including: larceny, robbery, fraud, assault, drug use, and homicide. A unique sample of 973 juvenile detainees drawn from the administrative profiles in Taiwan and the coarsened exact matching method were utilized. Results show that compared to their nontattooed counterparts, tattooed juvenile detainees were significantly more likely to commit fraud, assault, drug abuse, and homicide by 3%, 13%, 9%, and 9%, respectively. In contrast, tattooing was not significantly associated with larceny or robbery. From a policy perspective, given the significant link between tattooing and criminal behavior, the presence of a tattoo in adolescents may serve as a valuable indicator regarding adolescents’ high probability of committing crimes.     

组织模块化对组织价值创新的影响:基于产品特性调节效应的实证研究

组织模块化所催生的竞合机制与模块整合模式充分彰显了开创价值创新的优越。本文以产品特性为调节变量,对组织模块化与组织价值创新之间的影响机制进行了实证分析。结果显示,在组织模块化过程中,单纯的组织结构构建并不能够带来企业的价值创新,只有制度设计才是组织模块化价值创新的深层诱因;而引入结构构建匹配后,模块化制度设计对组织价值创新的影响更加显著,这在某种程度上说明了产业模块化向组织模块化过度的必然性;在行业表现出产品设计信息的高度依赖性和信息较难写入介质等特性时,组织模块化将难以开展,并由此影响组织价值创新,也进一步明确了模块化的行业适用范畴。     

消费者偏好背景下的买方抗衡势力形成与影响

与以往研究关注产业链内部因素不同,对于厂商利用消费者偏好因素的买方抗衡势力形成机理和影响的研究考虑了市场环境因素作用的买方抗衡势力理论研究新视角。将消费者偏好的市场差异建模为同一产品在不同市场中消费者效用差异,基于外部选择博弈和Hotelling博弈的基本原理,构建综合反映上、下游厂商纵向关系和市场内厂商间横向关系的博弈模型。对下游厂商跨市场并购前后均衡结果的变化进行考察,得到下游厂商利用消费者偏好特征形成自身买方抗衡势力的机理以及该行为对厂商本身和竞争对手谈判势力、收益水平和规模带来的影响。研究结果表明,存在消费者偏好差异的市场间厂商并购行为不仅可以提升合并厂商自身买方抗衡势力和收益,也不会对竞争对手造成负面影响,甚至可以提高部分竞争对手的买方抗衡势力、收益和规模,产生与水岸效应相反的结果。同时,对均衡结果进行福利分析,表明下游厂商的并购行为将提高总产业利润,但会降低消费者剩余和社会福利。
