技术源于生命,而非基于知识的某种创新或属于知识的分支。物在认识论的层面即理论科学的层面,是经由“起诉”而被纳入“范畴”的存在物。由此,在范畴的序列中只要有物存在,它就是存在物,它不仅符合知识的秩序,而且服从于作为生产的技术将其带向在场的摆置与设定。在技术停摆之处,知识以科学研究的方式为技术打开新的生产视角与进程,而这一生产之完成又伴随着对知识的再创制、再生产。因此,如果将知识理解为存在物层面的知识,即科学知识,那么,技术与知识的关联便凸显为:作为“生产”的技术为存在物层面的理论科学奠基,而对知识的探求,实质上是对技术所擅长的“缘起—招致”的生产方法的探求,即对技术本身之探求。  相似文献

随着我国生态文明建设的不断推进,促进供应链协同减排成为生产和消费领域落实绿色发展理念的重要举措。在绿色供应链的管理实践中,不同类型的供应链核心企业在进行减排决策时会有不同的侧重点,因此供应链权力的结构成为影响供应链减排水平的关键因素。本文在一个由两个制造商和一个零售商组成的两级供应链中研究了不同权力结构下的供应链最优减排和定价决策问题,分别给出了零售商主导和制造商主导的Stackelberg-Nash博弈均衡解,并分析了产品的单位生产成本、单位批发价格、碳税税率等参数对供应链最优决策的影响。本文的研究结果表明:(1)在两种供应链权力结构下,当产品的单位批发价格固定时,降低产品的生产成本都可以促使制造商提高减排水平;但是当产品的单位生产成本固定时,提高产品的批发价格却不一定总是能够激励制造商提高减排水平;(2)在两种供应链权力结构下,对于低排放行业的制造商来说,提高碳税税率可以增加产品的减排水平,但是对于高排放行业的制造商来说,提高碳税税率反而会降低产品的减排水平;(3)一般来说,零售商占主导地位的供应链中产品减排水平和供应链总利润相对较高,供应链碳排放总量相对较低。最后,与供应链集中决策模式相比,随着产品批发价格的增加,两种分散决策模式下的供应链双重边际效应逐渐增强。数值实验结果显示:在碳税税率的一定取值范围内,这种双重边际效应会使得两种分散决策模式下的产品最优减排水平和供应链碳排放总量均优于集中决策模式。本文的研究可为碳税政策下供应链的协同减排提供有益的管理启示。  相似文献

刘庆邦着眼于我国城乡社会结构的变迁,多年来坚持书写农村题材和普通矿工的平凡生活,新世纪以来创作的“保姆在北京”系列小说则将创作视点转移至进城打工的保姆群体,不变的是他对底层百姓的人道主义关怀及对人性问题的深入思索。不论是城乡交叉地带的煤矿叙事所呈现出的物理空间、心理空间和社会空间,还是“保姆在北京”系列小说中空间权力对进城乡下女性的规约与限制,都表现出刘庆邦小说明显的空间意识,也体现了他小说创作的独特价值。  相似文献

This study examines the effect of board size on the economic impact of bank mergers and acquisitions (M&A) in the US. Using a hand-collected dataset of 508 M&A between 2012 and 2018, we find that board size is negatively related to acquirer excess returns. In an additional analysis, we show that large boards have positive value implications for banks that combine the CEO and chairman roles as well as for large banks. Our findings indicate that a “one-size-fits-all” approach to board size is not necessarily in the interests of shareholders; instead, a more flexible and proactive formulation is needed.  相似文献

There is increasing research attention as to how SMEs might realize corporate social responsibility opportunities. Most studies focus on the pursuance of responsible business strategies that result in favourable business outcomes. This study investigates SMEs who actively participate in CSR activities in a south-eastern European country during the economic crisis of the Eurozone. Data collected reveals that stakeholder salience and proximity moderate the relationship between CSR and financial performance. The context of this study is important as it addresses the paucity of research carried out in countries during economic crisis and sheds light on the positive aspects of CSR practices adopted during crisis.  相似文献

广大农村地区是涵育中华优秀传统文化的根据地,乡村治理体系建设是新时代国家治理现代化、乡村振兴战略的重要条件。受传统宗族观念、家国情怀和邻里互助文化影响,乡村社会中公共空间普遍存在。在基层社会构建公共空间、培育场所精神,需借助物质空间、精神空间、社会空间的有机融合,加快乡村治理政策的落实。公共空间培育能够化解当地居民生产生活实践中的纠纷和难题,助推乡村治理体系建设,更好地服务于乡村振兴战略,促进和谐社会的建设与发展。  相似文献

构建由政府、企业和消费者组成的绿色技术创新系统演化博弈模型,分析了不同情形下参与主体策略选择对系统均衡策略影响的演化过程,并借助系统动力学实验方法进行了实验模拟论证。研究发现:(1)在绿色技术创新演化博弈系统所有可能的均衡策略中,只存在三个稳定的均衡策略,其中,绿色产品消费的经济收益和绿色技术创新品牌收益是驱动博弈系统向不同稳定均衡策略演进的重要动力。(2)企业绿色技术创新品牌收益和消费者绿色产品消费的经济收益是影响博弈演化系统最终向不同稳定均衡策略演进的主要因素。(3)在均衡状态(1,1,1)和均衡状态(1,0,0)下,通过促进消费者采取购买绿色产品策略对绿色技术创新系统的影响更为显著;在均衡状态(1,1,0)下,促进消费者采取购买绿色产品策略对绿色技术创新系统的影响更为显著,而提高市场规制强度和企业绿色技术创新意愿的影响效果较为微弱。  相似文献

Strong orthogonal arrays (SOAs) were recently introduced and studied as a class of space‐filling designs for computer experiments. An important problem that has not been addressed in the literature is that of design selection for such arrays. In this article, we conduct a systematic investigation into this problem, and we focus on the most useful SOA(n,m,4,2 + )s and SOA(n,m,4,2)s. This article first addresses the problem of design selection for SOAs of strength 2+ by examining their three‐dimensional projections. Both theoretical and computational results are presented. When SOAs of strength 2+ do not exist, we formulate a general framework for the selection of SOAs of strength 2 by looking at their two‐dimensional projections. The approach is fruitful, as it is applicable when SOAs of strength 2+ do not exist and it gives rise to them when they do.

Modeling spatial overdispersion requires point process models with finite‐dimensional distributions that are overdisperse relative to the Poisson distribution. Fitting such models usually heavily relies on the properties of stationarity, ergodicity, and orderliness. In addition, although processes based on negative binomial finite‐dimensional distributions have been widely considered, they typically fail to simultaneously satisfy the three required properties for fitting. Indeed, it has been conjectured by Diggle and Milne that no negative binomial model can satisfy all three properties. In light of this, we change perspective and construct a new process based on a different overdisperse count model, namely, the generalized Waring (GW) distribution. While comparably tractable and flexible to negative binomial processes, the GW process is shown to possess all required properties and additionally span the negative binomial and Poisson processes as limiting cases. In this sense, the GW process provides an approximate resolution to the conundrum highlighted by Diggle and Milne.  相似文献

Despite agility’s increased importance for public relations, the change process from traditional, hierarchically structured public relations to a dynamic agile entity has not yet been comprehensively investigated. This article tackles the research desideratum by discussing this change process from a structuration-theoretical perspective. The subsequent empirical analyses via two qualitative studies from the field of corporate communications focus on the perspective of consultants. These experts support the communication management in this change process with their expertise and neutrality, which the public relations departments themselves lack. Thus, consultants are key contacts for an explorative analysis of the change process toward more agility. In the first study, 39 consultants were interviewed about the change processes that they have guided in order to transform public relations into an agile department. The subsequent case study focuses on an internationally active medical technology manufacturer and analyzes their experience with consulting throughout the agile change process in their public relations department. The results show that the concept of recursiveness is central to the successful implementation of agility in public relations. Expressed in the language of structuration theory, consultants aim to develop rules and resources as modalities that describe an agile structure and then translate them directly into actions. These modalities are continuously developed via sprints, a dynamic process that results in the constant adaptation of the agile structures until the desired result is achieved. The results illustrate the advantages of a neutral, outside authority for the implementation of such a change process.  相似文献
