遴选合适的科研机构以整合成科研协同力量对于应对重大公共危机,尤其是对于防治和遏制新型冠状病毒肺炎等重大紧急疫情至关重要。首先,构建科研力量协同整合潜在对象识别理论模型,并在此基础上构建识别方法。以突发重大公共危机中的诊断试剂科研攻关为研究对象,以诊断试剂领域科研力量协同整合作为案例进行实证研究。最终识别出7个协同合作群组及29个关键核心机构,而且可将其整合为针对不同科研攻关需求的科研力量。结果还表明,在整合诊断试剂领域科研力量时,高校是与其它机构衔接的主要核心纽带,来自国家层面的科研院所及军队系统机构可以提供有力支持,而高新技术企业也是不可忽视的重要力量。 相似文献

由共享思想衍生的财务共享服务在当前的我国大型企业中已经得到较广泛的运用,当企业的业务线撤销财务权力后,所带来的财务共享中心的权责问题成为了阻碍财务共享服务提升流程处理效率的因素之一。通过对决策事件进行影响度以及风险性的划分并形成决策矩阵,探析在不同组织层级下财务共享中心的具体决策权之所在以及财务共享中心对于企业应急事件信息处理的反应系统,以期为财务共享中心的权责问题决策提供参考。 相似文献

The increasing magnitude and frequency of landslide-related disasters exposes weaknesses in disaster risk reduction (DRR) policy. One of the underlying reasons is that DRR policies tend to focus only on the physical aspects of the problem (i.e. mass movement processes) while neglecting the level of vulnerability of exposed populations to landslide threats, which affects the types and magnitude of adverse consequences. This neglect is a typical symptom of the remoteness that can exist between public administrators and local communities and undermines the implementation of participatory risk management. Certain dimensions of vulnerability depend on how communities relate to the issue of disasters based on their intuitive or rational judgment, i.e. their perception of risk. This paper seeks to shed light on the need for an understanding of risk perception based on the findings from a survey of residents in the city of Angra dos Reis, Rio de Janeiro, Brazil, to be taken into account in aiming at a more efficient landslide risk management policy. The survey was carried out through semi-structured face-to-face interviews with residents of three typical hillside communities in this municipality. In general, the study found that residents will often weigh landslide risks against other threats and opportunities existing where they live. It also found that community members find it difficult to see themselves as agents of change in the environment where they live and in mitigating landslide risks, and that better communication is needed between the government agencies involved in risk management and local residents. 相似文献

文章利用2007-2017年我国93家区域商业银行的面板数据,并结合省级宏观经济数据和地方官员变更数据,实证考察了中国地方官员变更引起的经济政策不确定性对区域商业银行风险的重要影响。研究结果表明:(1)地方官员变更引起的政策不确定性增大了区域商业银行风险;(2)地方官员变更引起的政策不确定性,通过提高银行的资产收益率降低了商业银行风险;而不确定性时期的财政扩张,通过降低银行资产收益率增大了商业银行风险;并且财政扩张的负面影响大于政策不确定性的正面影响;(3)各省的市委书记发生职位更替引起的政策不确定性对区域商业银行风险的影响更大。文章研究为新时代背景下的金融供给侧结构性改革、政府宏观经济政策的制定以及财政体制与金融体制之间的联系提供参考。 相似文献

Motivated by the requirement under the Dodd-Frank Act that all large bank holding companies create a stand-alone, board-level risk committee, this paper investigates the association between such a committee and regulatory risk both before and during the financial crisis. I focus the analysis on the set of banks that did not have a risk committee in place prior to the Dodd-Frank Act, as these are the banks that were most affected by the regulation. I find that matched control banks with a risk committee in place had higher capital ratios during the financial crisis, but lower capital ratios during more stable economic conditions relative to the banks without a risk committee. This paper contributes to the literature by narrowly investigating the effects a board-level risk committee, by focusing on a risk measure that is of interest to the regulators who implemented the new regulation, and by documenting that this association changes over time which highlights the importance of estimating the effects of new regulations across different economic conditions. 相似文献

This paper examines the pro-cyclicality of implicit risk weights of credit exposures and the potential contribution of accommodative monetary policy using data for the Czech Republic. The empirical results indicate that risk weights behave pro-cyclically under the IRB approach and acyclically under the STA approach. The pro-cyclical behaviour of IRB risk weights is caused primarily by the retail exposures, the strongest effects being in the highest and lowest quantiles of risk weights. The risk weights for retail exposures behave pro-cyclically not only with regard to the business cycle, but also with respect to the financial cycle and house price growth. In addition, monetary policy easing contributes to the pro-cyclicality in higher quantiles of risk weights. 相似文献

Expected shortfall (ES) is a popular risk measure and plays an important role in risk and portfolio management. Recently, change-point detection of risk measures has been attracting much attention in finance. Based on the self-normalized CUSUM statistic in Fan, Glynn and Pelger (2018) and the Wild Binary Segmentation (WBS) algorithm in Fryzlewicz (2014), this paper proposes a variant WBS procedure to detect and estimate change points of ES in time series. The strengthened Schwarz information criterion is also introduced to determine the number of change points. Monte Carlo simulation studies are conducted to assess the finite-sample performance of our variant WBS procedure about ES in time series. An empirical application is given to illustrate the usefulness of our procedure. 相似文献

文章基于溢出指数和波动溢出网络方法,从静态和动态分别度量我国金融系统不同子市场间的风险联动水平及变动趋势。研究结果表明,我国金融系统风险溢出效应整体水平较高,各市场间联动性较强;市场内部滞后效应大于市场之间溢出效应,两两有向溢出效应具有强不对称性;作为我国金融系统的风险中心,货币市场始终处于风险溢出方,但在金融危机时期,其对外风险溢出效应相对减弱,而大宗商品市场、资本市场、房地产市场等其余市场的风险溢出效应相对增强。值得注意的是,当前我国金融系统整体风险溢出水平较高,市场间风险相关性较强,需要进一步加强系统性风险的监测与防范。 相似文献

This paper examines the internal implications of branding within higher education, a specific context which is dominated by the co-existence of strong professional logics and identity structures. We focus on how and whether academic faculty identify with the branding practices undertaken by their respective institution. The paper proposes a communicative perspective on brand identification to understand how academic faculty relate to and make sense of the brand. The findings, from responses of 65 faculty members at five business schools, indicate widespread indifference and non-identification with brand messages. Specifically, we identify four types of disconnects between faculty members and branding practices of their respective schools, namely ambiguity, emptiness, misalignment, and irrelevance. The evidence of these disconnects, we argue, suggests that the faculty members refrain from relating the brand to their own identities. Although individuals relate to discourses around the brand, these are often not internalized and do not thereby impact on their individual identity. Rather than navigating between identity tensions, they eschew identification altogether. We contribute to research on how branding works inside contemporary organizations – including higher education - through questioning the role of identity in branding processes seen as the management of meaning. 相似文献
