以2001年至2008年间非金融类、非外资类正常交易A股公司为研究样本,考察财务报告舞弊行政处罚是否传递了可感知审计质量信息,实证研究结果表明:投资者总体上并不认可财务报告舞弊行政处罚传递了可感知审计质量信息,仅当投资者观察到反映坏消息的审计意见(如审计师出具非标审计意见、审计意见未改善等)和反映审计师声誉信息(如审计师受到行政处罚)的情况下,投资者才认为财务报告舞弊行政处罚传递了可感知审计质量信息。 相似文献

广交会是目前我国最大的综合性国际贸易盛会,每年都吸引了大量国内外客商到场参加。本文以广交会场馆内外的翻译工作者对广交会的响应情况作为研究重点,通过对广交会翻译的问卷调查及访谈,分析和研究广交会翻译对于广交会这一季节性旅游的地方响应。响应的人群主要为学生及社会工作者,其响应的方式可分为学校组织与个人自发响应。翻译工作者在广交会的这种季节性的旅游效应下不仅获得了学习和锻炼的机会,而且可以赚取更多的兼职收入,他们都对广交会的工作有较高的评价。 相似文献

Severe socio-economic issues that threaten peace, life or wellbeing of humans in specific regions of the world cannot be solved by any single actor. Wide networks of political, business, governmental, non-profit and humanitarian organizations are to be involved to change existing practices. Despite conflicting interests and competing behavior, involved organizations need to act collectively to initiate the change of commonly accepted practices, i.e. institutions. This is the space in the present study for examining network mobilization as a collective means to change institutions. Our aim is to answer the question: How are networks mobilized in crisis management to initiate institutional change processes in socio-economically turbulent contexts? We provide a framework of network mobilization for institutional change built on the IMP rooted network mobilization research and institutional entrepreneurship discussion. The framework is reflected upon by means of insights from an interview-based case study with representatives of governmental and non-governmental organizations involved in worldwide humanitarian peace-building. We identify, firstly, incentivizing, reticent and adaptational behaviors of network mobilizers to utilize legitimacy and relationship sediments as mobilization enablers. Secondly, these behaviors help network mobilizers to overcome actor visibility and unpredictability as mobilization obstacles in turbulent contexts. 相似文献

We study a location-allocation-routing problem for distribution of the injured in a disaster response scenario, considering a three-type transportation network with separate links. A circle-based approach to estimate the impacts of the disaster is presented. After formulating relations for computing the percentage of the injured, the destruction percentage and the damage-dependent travel times, the problem is formulated as an integer nonlinear program. We utilize a genetic algorithm and a discrete version of the imperialist competitive algorithm for solving large problems. An empirical study focused on earthquakes in Tabriz, Iran, illustrates applicability of the proposed model and performance of the proposed algorithms. 相似文献

This paper applies Kim and Wardes (2004) stratified Warners randomized response model to Mangat and Singhs (1990) two-stage randomized response model. The proposed stratified randomized response model has an optimal allocation and a large gain in precision. Hence, the estimator based on the proposed method is more efficient than Kim and Wardes (2004) and Mangat and Singhs (1990) estimators under the conditions presented in both the case of completely truthful reporting and that of not completely truthful reporting by the respondents. 相似文献

突发事件的影响不再仅仅是一个个体、一个企业或者一个地区,个体和组织的频繁外界联系在促进群体共同繁荣的同时也加大了自身处理突发事件的难度。作者试图对松耦合形态的供应链组织所面临的突发事件进行研究,通过个案分析结合项目管理理念找出一种切实可行的微环境应急供应链运作形态。 相似文献

Research efforts on ambulance response times for Emergency Medical Services (EMS) calls have been made for decades, especially in developed countries, using different techniques and with varying objectives. In Brazil, a developing country, the scarce scientific production on this vital indicator prioritizes scenarios for EMS in cities with more than one million inhabitants. This shows the importance of extending research to the reality of small and medium-sized cities. This paper presents SAMU, the Brazilian EMS that follows the Franco-German emergency medicine model, compiling numbers related to service at the national level. The use of quantile regression allows the identification of the RT for the EMS and helps to explain the effects of factors at the system level, at the patient level, and specific factors on response time intervals of Southwest Paraná SAMU. This specific EMS, characterized as an inter-municipal consortium of prehospital services, is responsible for prehospital emergency care for an approximate population of 635,000 inhabitants in 42 small towns in the State of Paraná in southern Brazil. From the analysis of the records of 12,050 ambulance dispatches, it was possible to identify the average ambulance response time of 14 min and 25 s. The regression model was able to explain the influence of the independent variables at the system level (presumed severity of the emergency, ambulance dispatch time, and ambulance travel time), at the patient level (age, gender, and characteristic of the emergency) and specific variables of the emergency (day of the week and time of day) on the dependent variable response time over the quantiles, showing that the dispatch time, travel time, time of day, service to male patients and critical cases influence the ambulance response time. This work contributes to deepening the understanding of the management of EMS operations in a developing country, allows the comparison of the RT identified in relation to other countries, and identifies factors that impact the RT for other actors directly or indirectly involved. The practical implications are also presented, as well as how the study impacts the decision-making and management process of the EMS in the short, medium and long term. 相似文献

A coordinated approach is developed to integrate three preventive measures (i.e. building reinforcement, reinforcement of road networks, and facility location of relief supplies), with the objectives of minimizing budgets and risk-induced penalties. The Conditional Value-at-Risk is employed as a decision-making tool to evaluate diverse decisions of prevention based on the degree of risk aversion. Based on a real-world case of an earthquake, a series of scenarios were designed, and the applicability of the proposed model was studied. The coordinated approach for investing preventive measures is cost-efficient in helping reduce the impact of disaster on society. 相似文献
