Robust influence diagnostics for generalized linear models with continuous responses

This article introduces two parametric robust diagnostic methods for detecting influential observations in the setting of generalized linear models with continuous responses. The legitimacy of the two proposed methods requires no knowledge of the true underlying distributions so long as their second moments exist. The performance of the two proposed influence diagnostic tools is investigated through limited simulation studies and the analyses of an illustration.     

商务信用信息纳入征信系统的方法和途径研究——以辽源市为例

商务信用信息是指各级商务主管部门及商协会在依法履行管理职责的过程中,收集的反映市场主体信用状况的各类信息.商务信用信息能够比较全面的反映企业与个人的信用状况,但目前,这部分信息尚未纳入征信系统,这在一定程度上影响了金融机构及政府相关部门对该部分信息的应用.研究并采取相应措施将商务信用信息采集到征信系统,是对征信系统内容...     

An investigation of restaurant food safety performance: A comparison between ethnic and nonethnic and chain and independent restaurants in Louisiana

This study examines health inspection data from casual dining restaurants and compares differences of food code violations between ethnic and nonethnic restaurants. A total of 7,415 violations were retrieved from the restaurant inspection reports of 769 restaurants. Ethnic restaurants have more violations than nonethnic restaurant in categories related to food time/temperature violations, cross contamination, and food condition/surface/labels. Nonethnic and chain restaurants had fewer behavioral violations than ethnic and independently operated restaurants. Ethnic restaurants were 1.74 times more likely than nonethnic restaurants to have critical violations. Meanwhile, independent restaurants were 1.64 times more likely than chain restaurants to have critical violations.     

Employee satisfaction trajectories and their effect on customer satisfaction and repatronage intentions

Does improving employee happiness affect customer outcomes? The current study attempts to answer this question by examining the impact of employee satisfaction trajectories (i.e., systematic changes in employee satisfaction) on customer outcomes. After accounting for employees’ initial satisfaction levels, the analyses demonstrate the importance of employee satisfaction trajectories for customer satisfaction and repatronage intentions, as well as identify customer-employee contact as a necessary conduit for their effect. From a macro perspective, employee satisfaction trajectories strongly impact customer satisfaction for companies with significant employee–customer interaction, but not for companies without such interaction. From a micro perspective, employee satisfaction trajectories influence customer repatronage intentions for frequent customers, but not for infrequent customers. These effects are robust to controlling for previous customer evaluations and recent employee evaluations. Overall, these findings extend the dominant view of examining static, employee satisfaction levels and offer important implications for the management of the organizational frontline.

     

基于Python平台通过单因子指标法进行地下水质量评价

水质评价关系到水质质量,常见的评价方法有层次分析法、综合评价法等,这些方法评价过程非常复杂,单因子评价方法相比具有操作容易.实际中单因子进行评价时存在概念理解难、计算容易出错等问题.为解决单因子计算问题,本文提出采用Python编程语言进行单因子评价.本文详细分析了Python进行单因子评价流程,从数据采集、数据清洗、数据处理、系统实现进行分析.应用结果表明基于Python编程的单因子评价方法具有评价效率高、准确度高优点.     

逼真度度量方法及其在配送中心仿真中的应用

构建了物理模型逼真度、数据建模方式、作业流程简化程度三个维度的逼真度层次划分框架,用模糊层次分析法(Fuzzy AHP)对模型逼真度进行定量度量。该方法既可在仿真实施前帮助建模者建立较规范的逼真度设计,又可在建模后对已有模型的逼真度进行定量度量,有效地保证了仿真活动的规范性和仿真代价与仿真效用的合理化。最后以某机械零部件配送中心仿真为例,对该配送中心规划的不同时期的仿真模型进行逼真度设计和度量,进而得到有关配送中心仿真逼真度设计与管理的一般性结论。     

International Evidence on the Matching Between Revenues and Expenses

This study investigates the time‐series trend and determinants of matching between revenues and expenses in a sample of 42 countries. We find that the decline in matching documented by Dichev and Tang ( 2008 ) is not unique to the United States, but is a worldwide phenomenon. Our results show that matching is weaker in countries with (i) wider use of accrual accounting; (ii) a larger proportion of firms reporting significant special items; (iii) slower economic growth; (iv) more research and development activities; (v) larger service sectors; and (vi) stronger investor protection. We find no evidence that mandatory adoption of International Financial Reporting Standards affects matching. Changes in accounting and economic factors collectively explain the downward trend in matching. Overall, the results suggest that both accounting and economic factors are important determinants of matching over time and across countries.

Financial Sector Volatility,Banking Market Structure and Exports

This paper assesses the impacts of financial sector volatility and banking market structure on industrial exports. By utilising the specification of Rajan and Zingales (American Economic Review 1998; 88 , 559) on the cross‐country, cross‐industry data from Manova (Journal of International Economics 2008; 76 , 33), we find that financial sector volatility, measured as the standard deviation of the growth of private credit, and banking market structure, measured as the share of the three largest banks’ assets in a country, respectively exert significantly negative and positive impacts on industrial exports, particularly for those industries that are more externally financially dependent. The findings are robust to a variety of kinds of sensitivity analysis and thus lend support to the notion that a more stable and concentrated banking system is important to the exports of those industries that rely more on external finance.
