The Engineer and The Plumber: Mediating Mumbai's Conflicting Infrastructural Imaginaries

Two decades ago, the rules governing the provision of piped municipal water supply in Mumbai became linked to the policy frameworks governing eligibility for a property titling scheme. This article outlines the ideological basis and practical implications of the shift, as well as the contradictions of the new regulatory regime. The article demonstrates how these contradictions have been mediated by the material and practical knowledge, embodied expertise, local authority and wide‐ranging socio‐political work of two sets of actors: municipal water engineers and a cast of characters known locally as ‘plumbers’. The social, political and hydraulic imaginaries animating the work of ‘plumbing’ are bound up with a temporal and spatial imaginary distinctly at odds with the network‐flow conception of hydraulic engineering within which the work of water supply planning and distribution in Mumbai is conceptualized, materialized and institutionalized. The hydraulic and legal contradictions of these clashing infrastructural idioms––of flow and event––have rendered the regulatory framework highly unstable. These contradictions eventually erupted in Mumbai's waterscape, leaving the city's water infrastructures suspended in a highly politicized state of limbo between dueling infrastructural imaginaries.     

中国文化情境下包容性领导对员工敬业度的影响

包容性领导是一种当前备受关注的新型领导方式。本文通过对国内95家企业共665位员工进行问卷调查，主要考察包容性领导对员工敬业度的影响、组织认同的中介作用和平衡互惠的调节作用。研究结果显示：包容性领导显著正向影响员工敬业度；组织认同在包容性领导与员工敬业度之间起到中介作用；平衡互惠在组织认同与员工敬业度之间起到调节作用；并且平衡互惠正向调节组织认同对包容性领导与员工敬业度的中介作用。因此，企业应该采取开放包容的领导方式，通过提高员工的组织认同感，提升员工敬业度。     

Multiple dimensions of mediation within transnational advertising production: cultural intermediaries as shapers of emerging cultural capital

The paper re-conceptualizes cultural intermediaries as shapers of “emerging cultural capital” (Prieur, A., and M. Savage. 2013. “Emerging Forms of Cultural Capital.” European Societies 15 (2): 246–267; Savage, M., F. Devine, N. Cunningham, M. Taylor, Y. Li, J. Hjellbrekke, and A. Miles. 2013. “A New Model of Social Class? Findings from the BBC’s Great British Class Survey Experiment.” Sociology 47 (2): 219–250) and re-frames their practice of signification and negotiation as informed by “multiple dimensions of mediation.” Drawing on a case study of Nike’s transnational advertising production and interviews with key actors within the context of production, the paper examines how the creative/cultural labour process cuts across global and national fields of cultural production and consumption through which popular culture and middle-brow tastes were mediated, signified and represented. In particular, a television campaign for the Japanese youth market was critically analysed to reveal how specific new tastes, lifestyles and consumption practices were legitimized as emerging forms of cultural capital. Consequently, their taste-making practices are profoundly implicated in symbolic struggles and cultural changes emerging within/from the increasingly “globalizing” field of cultural production.     

Researching taste: an interview of Antoine Hennion

ABSTRACT

Antoine Hennion is a Professor of Sociology at the Centre de Sociologie de l’Innovation (Mines-Paris Tech, PSL/CNRS). He has been researching taste and cultural practices through a pragmatic lens for three decades. He has developed an original and impactful theoretical framework bridging the Actor-Network Theory to Cultural Studies. More precisely, he reconceptualized the notions of mediation and attachment. Antoine Hennion has explored various empirical settings, including music, wine, and sports. More recently, he has contributed to a large research project on migration. His books and academic articles have had an impact on Sociology, and are getting greater attention in consumer research.     

新审计报告与资本市场的信息反应——来自股价同步性和股价预测能力双维度的经验证据

新审计报告准则的施行旨在增加审计报告的信息含量及其决策相关性。以2015—2018年沪深非金融上市公司为样本，研究发现新审计报告施行后，上市公司的股价同步性显著下降，公司特质信息含量比例显著上升，股价特质信息效率显著提升,同时新审计报告的施行产生了增量信息。在此基础上，进一步分析新审计报告准则对资本市场特质信息效率的传导机制，发现投资者关注度对新审计报告(关键审计事项的披露数量)影响资本市场特质信息效率的过程中表现出显著的部分中介效应。分样本检验的结果表明，虽然AH股共同上市公司和非AH股共同上市公司之间的结果存在细微差异但整体趋势相似。通过对新审计报告的影响的分析，可以更好地理解该政策对资本市场的影响。     

基础设施对中国经济增长的影响及机制研究*——基于扩展的Barro增长模型

基础设施既可以作为特殊的资本存量直接促进经济增长，又可以通过促进投资和劳动力增加（增加生产要素数量）以及提高存量资本和劳动力的边际生产率（提高生产要素效率）间接促进经济增长。本文构建了一个扩展的Barro经济增长模型，并利用中国1992—2016年省级面板数据和中介效应模型对两条机制进行实证检验。结果发现：基础设施对经济增长具有促进作用，但对交通、能源、通信三类基础设施的影响以及在2008年金融危机前后均表现出异质性。直接效应呈动态上升趋势，中介效应则逐渐下降。针对异质性的原因，本文进一步采用非线性模型进行检验。结果表明我国基础设施对经济增长的促进作用主要表现为规模扩张型、数量型或外延型，而不是以质量型和内涵型为主的形式。能源和通信基础设施对经济增长的总效应具有规模效应，交通基础设施的规模效应不显著，但也对经济增长具有持续促进作用。这说明目前我国三类基础设施仍然具有较大投资潜力。其中的关键是要通过基础设施建设提高生产要素效率。     

高铁开通提升了城市绿色发展效率吗——基于双重差分模型的实证检验

以高铁开通这一事件构造准自然实验，基于2006~2017年中国271个地级市的平衡面板数据，首先通过数据包络分析法测算城市绿色发展效率，进而使用双重差分模型和中介效应模型检验高铁开通对城市绿色发展效率的影响及作用机制。研究发现：（1）整体上，高铁开通显著提升了城市绿色发展效率。在缓解内生性问题和进行多项稳健性检验后，这一结论依然成立。从动态效应上看，高铁对城市绿色发展效率的拉动呈逐年上升的趋势。（2）机制分析表明，高铁开通凭借创新效应、结构效应与配置效应提升了城市绿色发展效率，其中创新效应发挥的作用最强，而结构效应的影响较弱。（3）异质性研究发现，高铁开通对城市绿色发展效率的拉动作用在东部地区和大中型城市更为显著。（4）基于地理距离圈层的扩展分析表明，高铁开通对不同圈层内城市绿色发展效率的促进效应呈"倒U"型变化趋势，且在距中心城市200 km处达到最大。     

生产性服务业集聚与全球价值链地位攀升

结合中国工业企业数据和城市经济数据，运用工具变量回归从专业化和多样化层面探讨中国生产性服务业集聚对制造业全球价值链地位的影响。研究发现，从整体上看，不论是专业化还是多样化，生产性服务业集聚均能够显著提升中国制造业的全球价值链地位。分样本检验显示，生产性服务业集聚对全球价值链地位的提升作用主要存在于沿海省份、资本和技术密集型行业以及中小企业。在作用机制方面，生产性服务业专业化集聚主要通过提高创新水平和推动全要素生产率促进全球价值链地位的提升，而多样化集聚则通过加快要素流动和推动全要素生产率来提升全球价值链地位。     

How and when servant leaders fuel creativity: The role of servant attitude and intrinsic motivation

Workplace creativity is critical to stay ahead in the current competitive hospitality industry. Recent research has suggested that servant leadership fosters creativity. However, there is a lack of research into the mechanisms and situations that make this link possible. This paper examines (1) employee servant attitude as a mediator in the servant leadership–employee creativity relationship, and (2) the role of intrinsic motivation in both the direct and the mediated relationship. Using structural equation modeling to analyze a sample of 259 hotel employees in Spain, we found that servant attitude is one of the mechanisms servant leaders use to foster creativity, and that this mediating role of servant attitude is strengthened as employee intrinsic motivation increases. However, when intrinsic motivation decreases, the mediation reverts and the leadership–employee creativity relationship becomes significant again. New light is shed on how and when servant leadership is most effective in fostering hotel staff creativity.
