广西金融发展与经济增长关系的实证研究：1978-2012

利用广西1978—2012年地区生产总值、银行贷款和银行存款的时间序列数据,建立了三者之间动态关系的向量自回归模型（VAR）。研究结果显示：银行贷款和银行存款对地区经济增长有促进作用,并且银行贷款的影响大于银行存款的影响;在10％的显著水平上,地区生产总值与银行贷款构成双向Granger因果关系;在5％的显著水平上,银行存款与地区生产总值之间只存在单向Granger因果关系。据此,提出了广西金融改革发展的政策建议。     

基于功能组分解原理的高压配电网可靠性评估方法及其应用

基于功能组分解原理,提出了同时考虑变电站主接线形式和高压配电网结构的可靠性评估模型;建立了包括系统性指标和节点性指标的可靠性指标体系;基于潮流计算和最优理论,建立了反映系统故障行为和优化校正行为的可靠性评估算法。并将上述方法应用于某市2015年高压配电网结构方案的可靠性评估。研究表明,通过该方法得到的高压配电网可靠性评估结果真实可信,该方法具有良好的应用前景。     

评价石油装备安全可靠性的一种新方法

为了能较全面、准确、高效地评价石油装备的安全可靠性，开展石油装备的运行可靠性研究和状态监测、故障诊断的研究工作，并将这两项研究工作有机地结合起来是十分必要的。方法的要点是：利用设备运行和大修的历史记录，研究设备的运行可靠性；选择合适的监测与诊断参数，建立数据库进行积累，了解故障的发生、发展趋势，进行定性和定量分析，用可靠性理论和方法研究故障发展的规律，探讨故障产生的原因，故障发展的速率，进而预测设备工作寿命。最后结合钻井泵研究的实际，探讨了此项方法的可行性。     

Smart city networks' governance: The Spanish smart city network case study

The governance of smart city networks emerges as a new research area intersecting smart governance and public networks studies. This work aims to contribute to the literature on smart cities governance by studying councillor's governance in complex networks and on network performance. To carry out this analysis, the Spanish Network of Smart Cities (RECI), one of the first of its kind and an international reference for city networks, is reviewed as a case study, with the main objective of establishing a theory on its global innovation capacity and operations, together with the local level spurring influenced on its members. A PEST (Political, Economic, Social and Technological) analysis was carried out in order to assess the impact of the smart city network both at local, national and international level. This research was completed with a consultation carried out among some of RECI's municipalities. The analysis of the results shows how RECI can be considered an example of a well organised network with quantifiable savings for its members, capable of configuring future policies in local administration, necessarily related to efficiency, digitalization and citizen-centricity and with key topics to build the future. The study also suggests recommendations oriented to potential improvements that smart city networks could undertake.     

资源特许经营权的物权性研究

资源利用的法律问题随着人类生活水平、技术水平的提高及资源稀缺性的加强而被重视。从资源保护的角度看,中国资源立法的缺陷,重要的不是公法意义上的资源管理法规的缺陷,而是私法保护体系的严重不足。文章明确了资源特许经营权的物权属性,提出资源特许经营权作为一种私权还需要物权法详细而具体的制度支持。     

Crowdsourcing and work: individual factors and circumstances influencing employability

The development of a fast and reliable Internet, new technologies online payment systems, and changes in work structure that enable and demand flexible working patterns have driven a move to a new form of Internet‐enabled labour exchange called crowdsourcing. Evidence from an in‐depth qualitative study is presented, focusing on selected users' interactions and experiences of working on two UK‐based crowdsourcing platforms. The paper shows that workers engaged in this form of labour exchange need to deploy existing employability skills and networks to effectively meet the challenges, and take advantage of the opportunities, that crowdsourcing presents. Individual factors and circumstances emerge as paramount for workers' continued engagement in this form of employment. Using selected components from an employability framework, the findings suggest that crowdsourcing can offer new pathways to practising skills and enhancing employability for some workers.     

Technology‐push,market‐demand and the missing safety‐pull: a case study of American Airlines Flight 587

Through a critical case study of the crash of American Airlines Flight 587, this paper draws upon ‘the Social Shaping of Technology’ (SST) approach to offer a reconceptualisation of the technology‐push and market‐demand model for High‐Reliably Organisations (HROs), providing support for a third factor, called here a ‘safety‐pull’. A safety‐pull is defined as organisationally supported reflexivity in which technology innovators and frontline operators collaborate to consider the potential implications of adopting new technologies in HROs and the complex ways this change may impact human operators' work performance, often in risky and unanticipated ways. In contrast to accidents occurring solely as the result of individual operator error, analysing the safety‐pull provides a way to tease out the wide range of factors that can contribute to HRO failures and offers a new SST perspective through which to examine high‐risk operations.     

Investment performance of “environmentally-friendly” firms and their initial public offers and seasoned equity offers

We employ a sample of 748 environmentally-friendly (or “green”) firms listed on U.S. stock exchanges to extend studies of the effects of socially responsible investment (SRI) on stock investment returns and the performance of initial public offerings (IPOs) and seasoned equity offerings (SEOs). Our empirical tests document positive and statistically significant excess returns for our environmentally-friendly firms and their IPOs and SEOs, in contrast to our control IPO and SEO samples which underperform. In summary, a “green” equity premium is evident in returns calculated from a variety of benchmarks.     

The impact of FIFA’s official announcements on the stock market of Qatar: The case of the 2022 World Cup

This study examines the impact of the FIFA’s official announcements on Doha Stock Exchange (DSE) of Qatar with respect to the 2022 World Cup. Using the abnormal unsystematic volatility method of Hilliard and Savickas (2002), our empirical findings reveal that the DSE market is sensitive to FIFA’s announcements about the 2022 World Cup. We find that four out of six FIFA announcements act as primary drivers to the DSE market volatility. The significant reactions of the DSE market to these announcements unveil the investors’ sentiments about the fate of the governmental and private expenditures on medium- and long-term projects undertaken in anticipation of hosting the 2022 World Cup. The results have some implications to investors in this newly emerging market related to this global sporting event. Any future announcements, good or bad, are likely to impact share prices in DSE market and trigger portfolio reallocation by local and international investors, leading to increased volatility.     

How the enterprise risk management function influences decision-making in the organization – A field study of a large,global oil and gas company

Risk management has been a discipline for decades. However, organizations have only recently begun to introduce a separate enterprise risk management (ERM) function. The aim of this study is to examine the transformation of the ERM function's influence in a company over time. We use a historical case study informed by social theory on how to influence others to investigate this phenomenon. The findings show that the construction of risk technologies over time triggers a change in the ERM function's influence on decision-making. Two processes of influence are used by the ERM function: selling new ideas and managing knowledge across boundaries. In the first process, the ERM function attempts to vertically influence top management's decisions regarding acceptance of new risk management technologies. In the second process, the ERM function attempts to horizontally influence decision makers to use risk knowledge in decision processes. Theoretically, our findings contribute to our understanding of how the ERM function influences decision-making in organizations over time.
