场域论视角下的城市社区建设

场域论社区发展理论认为,社区的本质是社会互动,社区是地域性社会内不同利益群体为了实现共同利益而整合起来的社会互动场域,社区发展的本质就是地域社会内居民的自组织能力的发展。该理论对发展我国社区建设理论具有建设性的启发和借鉴意义。     

从天命史观向社会进化史观的过渡--论清代学人为中国社会自我演变所做的史观准备

由“公羊学”所宣扬的天命史观,是将社会的变化视为天道运行“副本”的观念。它既宣扬“君权天授”,又承认“天命所授者博,非独一姓”,认定社会在周期性的循环中发展。但在整个中世纪,“君权天授”的观念一直是维护家天下专制制度的精神武器。在从古代社会向近代转型的过程中,“前清”学者在批评天命史观时,将主宰人类命运主体的“天”置换为“社会”;到了清代中期,“常州”学人则注意到“天命”史学中所包含的变易思想;晚清之时,恰遇“千年未遇之变局”,康有为等一方面援引前清学者的社会主体观念,另一方面则直接将公羊学的变易思想与西学相对接,于是,“通三统”、“张三世”、“《春秋》当新王”便被改造成社会进化论学说。     

现代节约的价值及其特征

现代节约既包含个人价值，也包含社会价值。与古代节约相比，现代节约的内涵更丰富，价值更高。它不仅指生产、生活、工作方面的节约，而且也包含节约人类创造出来的财富和尚未开发的自然资源；不仅是被动地抑制自己的物质消费来适应环境，而且还通过节约提高劳动生产率，更有效地利用自然资源创造出更多更好的财富以提高人类的生活质素，推动人类的发展。在新的形势下，重新审视节约的价值，对于推动具有中国特色的社会主义建设的发展具有现实的意义。

Analyzing mental health evaluation: moral and ethical dimensions

Now that evaluators have been sensitized to the importance of moral and ethical issues in their work, it is time to move beyond generalities and examine the moral and ethical implications of specific evaluation models in specific settings. This paper proposes a framework that can be used to examine moral and ethical dimensions of evaluation and illustrates it by analyzing a selected model of mental health evaluation. Such a systematic identification of moral issues can improve evaluation practice both proactively, by shaping the training of evaluators, and retrospectively, by contributing to meta-evaluation.     

A construal level analysis of organizational change processes

To effectively manage planned change and understand differences in leaders’ and recipients’ responses to it, it is essential to understand how change is cognitively represented by organization members. In this theory-development article, we draw upon construal-level theory (CLT) and conceptually explore the role of change construal level in explaining responses to organizational change. We discuss differences between change leaders’ and recipients’ change construals, and differences in the relationships between change construal level and the response to change as a function of the change activities taking place. Specifically, we argue that high-level (i.e., abstract) construals of change will facilitate the effective initiation of change when the focus is on equilibrium-breaking activities, and that low-level (i.e., concrete) construals will facilitate the effective implementation of change when the focus is on institutionalization of the change. We further propose that leaders’ engagement in visionary leadership increases the likelihood that their generally higher level construal of change will be integrated into recipients’ change construals, elaborating and elevating them, and that recipients’ engagement in upward prohibitive voice behaviors will increase the likelihood that their generally lower construal of change will be integrated into leaders’ change construals, elaborating and concretizing them. We discuss theoretical and practical implications of our framework.     

The ecosystem blueprint: How firms shape the design of an ecosystem according to the surrounding conditions

Ecosystems are formed by organisations that jointly create a value proposition that a single firm could not create in isolation. To deliver this value proposition, the partners need a focal firm, the orchestrator, to be align them towards the joint value proposition. Thus, how orchestrators design the alignment structure of an ecosystem is at the very heart of the ecosystem concept – yet it has not been sufficiently addressed by extant research. This is all the more true for the question of how the design of an ecosystem is shaped depending on surrounding conditions. This paper applies a qualitative study with ten cases and, based on the attention-based view of the firm, contributes to research on ecosystems in several ways. First, it explains which ecosystem designs are beneficial under which conditions. Second, it elucidates the structure and activities within ecosystems and shows that start-ups can be just as good ecosystem orchestrators as incumbents. Third, it explains the circumstances under which single vs. multi orchestrator ecosystems occur. Fourth, it presents the conditions when incumbents or start-ups make better orchestrators. Finally, it is among the first studies to apply the attention-based view to business ecosystems, and shows that doing so yields intriguing insights into this emerging field of research.     

Understanding manager resistance to blockchain systems

Blockchain technology has received much attention in the media and there is an increasing interest amongst organizations within financial services due to the potential benefits. As blockchain-based systems are a nascent technology, the requirements of the technology need to be understood, to allow blockchain systems to be successfully integrated within financial service organizations. There are gaps in academic research in understanding how managers evaluate the value of a blockchain-based system. This study develops a model to explain manager resistance to implementing blockchain-based systems in financial services organizations. This research advances the theoretical understanding of managers’ perspectives on blockchain-based systems and models their resistance to blockchain technology.     

具有卖空总量限制的多阶段M—SAD投资组合优化

文章提出具有卖空总量限制、阈值约束和V型交易成本的多阶段均值—半绝对偏差（M-SAD）投资组合优化模型。该模型分别运用均值和半绝对偏衡量资产的收益率和风险。由于交易成本的存在,该模型不满足无后效性的动态优化问题。文章将该模型近似为一般动态规划问题,提出一种新的离散迭代方法,并证明该算法是线性收敛的。最后,文章通过实证研究比较分析卖空总量限制和风险偏好系数取不同值时对投资组合最优策略的影响,验证模型和算法的有效性。     

多层次社会资本与农村老年人健康状况

文章分析了农村老年人多层次社会资本内涵,将其划分为个体家庭结构型、个体家庭关系型和个体家庭认知型社会资本,村庄公共社会资本和村庄团体社会资本,通过OLS回归分析方法检验了多层次社会资本对农村地区老年人生理、心理健康状况的影响关系,在此基础上考察了多层次社会资本对东、中、西部省份农村老年人生理、心理健康的影响,并对全样本回归分析结果进行检验。结果表明:①多层次社会资本对农村老年人健康状况具有显著促进作用。②多层次社会资本对不同省域间农村老年人健康状况的影响存在显著差别。③村庄公共社会资本对农村老年人心理健康水平和东、西部省份农村老年人生理健康水平具有显著影响,村庄团体社会资本对中部省份农村老年人心理健康状况具有显著影响。
