Value drivers of social businesses: A business model perspective

Hybrid organizational forms that combine commercial and welfare institutional logics play an increasingly important role in addressing the grand societal challenges we face today. Building on the literatures on hybrid organizations and social business models, we explore the characteristics of social businesses from a business model perspective. This study seeks to better understand the particularities and value drivers of hybrid social purpose in contrast to purely commercial business models. We follow a grounded theory approach and our findings are based on interview data from 17 social business firms. Building on social businesses' identified particularities, we propose four value drivers of social business models: 1) responsible efficiency, 2) impact complementarities, 3) shared values, and 4) integration novelties. We link our findings to the literature, contributing new insights into social businesses models and implications for practitioners.     

嵌套并联结构两阶段DEA下科技创新效率测度与分解

目前有许多研究将两阶段DEA模型应用到科技创新活动当中，一般将创新活动分为研发和转化两个阶段，为了进一步探讨不同转移转化方式下科技成果的转化效率以获得更多的详细信息，本文拓展了传统的两阶段DEA模型，考虑了嵌套并联结构的两阶段网络DEA模型，将科技创新活动分为科技成果研发阶段和科技成果转化阶段，并将科技成果转化阶段分为内部转化和外部转化两个并联子系统。本文选取14家中科院院属单位作为被评价对象，应用加权加法分解方法计算整体效率和各阶段子效率。通过将本文模型与传统两阶段模型进行对比发现，传统模型会低估科技成果转化效率。结果表明：整体科技创新效率均值偏低，科技成果研发效率均值高于科技成果转化效率均值，科技成果转化效率仍有很大的提升空间。科技成果转化阶段中内部转化效率普遍较高但是外部转化效率普遍较低，较低的外部转化效率是导致科技成果转化效率低下的主要原因。最后，本文将所有被评价单位分为四类机构，分析提高科技创新效率的实现路径，可以通过重点突破模式和渐进突破模式来实现整体效率的提高。

A dynamic business modelling approach to design and experiment new business venture strategies

Business Modelling has evolved as a key activity to reflect new business venture strategy by framing the way a firm will operate and how it will function in achieving its goals (e.g., profitability, growth, innovation, social impact). However, scholars and practitioners have criticized the adoption of a too static perspective in the design and use of conventional Business Model representations. Such a static perspective prevents nascent entrepreneurs experimenting with their Business Models and, as a result, identifying the most effective strategies, especially in terms of business sustainability and profitability. In this paper, we argue that combining conventional Business Model schemas with System Dynamics modelling results in a strategy design tool that may overcome several limitations related to a static view of Business Model representation. Mapping the different key elements underlying value creation processes into a system of causal interdependencies – through the use of simulation – allows strategy analysts and entrepreneurs to experiment and learn how the business reacts to strategic and organizational changes in terms of performance, innovation and value creation. As such, Dynamic Business Models provide useful insights to strategy formulation and business venturing by capturing how critical Business Model elements interact to produce enduring competitive advantages over time.     

The middling mobile: finding place in the liquid city

The middling mobile, differentiated by their modest and unsure mobility, are a vast of bulk of people who intend or expect to move on. As they travel, they tread differing intensities of rhythm and social embeddedness felt to be chaotic, constraining, liberating, or comforting. Owing to their aspirations to ‘get out’ of a rhythmic life, or to move somewhere familiar, the middling mobile use movement and rootedness to navigate and manage everyday life in the liquid city. My analysis offers a holistic exposition of a life that flows between mobility/immobility and rhythmic/arrhythmic forms, and the transitions between them.     

基于Hawkes因子模型的股价共同跳跃研究

本文首先比较了三种目前主流的共跳检验方法：基于LM检验的共跳检验、BLT共跳检验和FHLL共跳检验，结果表明，三种方法在识别共跳数量上差距明显，但三者结果的重合部分基本属于市场暴涨暴跌行情，说明共跳识别对市场剧烈波动的聚集性较为敏感。基于跳跃、共跳存在的聚集性问题，本文将Hawkes过程引入跳跃和共跳的研究，构建了基于Hawkes过程的因子模型，结果显示，基于Hawkes因子模型的MJ统计量、CJ统计量和实证数据的拟合程度较好，表明因子模型能够更好地描述跳跃和共跳的聚集性。     

怀疑意识、主体性及其他——论孙郁鲁迅研究中的哲学视角

哲学视角是孙郁的鲁迅研究中起步早、且一以贯之的一个方向，他独创性地将鲁迅与康德进行比较，认为在强调认识的有限性这一点上，二人不乏相似性。孙郁强调怀疑意识作为鲁迅思想的“内核”，并指出其在文化史上的意义。他以“主体性”思想为参照，对鲁迅思想和作品进行了深度解读，进而指出传统的“主奴文化”是形成“相互主体性”思想的障碍。概而言之，孙郁对于哲学视角的运用，并非纯粹的知识生产，具有鲜活的生命力和学术价值。

“百年未有之大变局”之哲学分析

当今世界正处于“百年未有之大变局”中。这是中国共产党对于世界新的时代特征的全新、科学和准确的研判。“百年未有之大变局”这一重大论断，具有深厚的马克思主义哲学的本体论基础、认识论基础、矛盾论基础和历史观基础。作为科学世界观与方法论，马克思主义哲学的辩证唯物主义和历史唯物主义为我们深刻认识和精准把握“百年未有之大变局”的深层本质和哲学依据提供了重要的认知性引导、方法论基础和实践智慧支撑。     

Children and Violence: Nurturing Social-Emotional Development to Promote Mental Health

The absence of violence against children is a fundamental children's right and a major milestone of civilized society. Similarly, reports on incidences of violence by children and youth, including severe cases with devastating consequences, speak to the need that the trauma of exposure to violence in childhood needs to be addressed. While violence and its risk factors are generally understood, what is less clear are the essential protective factors, how we can identify those as early as possible, and how we can use them to prevent and address the trauma of violence exposure in children and youth. In this report, I review pathways of child and youth violence through the lens of social-emotional development as a central protective factor. Negative emotions of frustration and anger can underlie violence and aggression. Kind emotions, such as caring and our ability to connect with others emotionally, can serve as social-emotional protective factors. A brief review of the central social-emotional processes and their development is provided, including the human capacity to feel with others and express empathy, be emotionally aware and care about the effects of one's own actions on others, and be able to regulate the self and their emotions. Given the negative widespread and long-term impact of exposure to violence, I describe research-informed attempts to prevent violence exposure across development. Taking a humanistic, strength-based perspective, the focus is on social-emotional protective factors to address violence and nurture mental health in every child. I conclude with recommendations for practice and policy.
