As an important part of the prep- aration work of World Expo Shanghai 2010,the organizers have launched a series of suc- cessful promotion campaigns in China, participating countries,BIE members' countries,etc.,as for developing aware- ness and conveying the concept of the worldwide grand events.Various methods are used in the promotion work,such as dedicating a 5.28-square-meter area at the core of the city to exhibitions,events and forums,and building a powerful and last- ing pilot example of sustainable and har- monious urban living. 相似文献

This article considers processes of urban development within the context of mega‐event preparations in Rio de Janeiro. We begin with a brief overview of these development processes, highlighting their connections to political and economic change in recent years. Proponents of these mega‐event‐led initiatives argue that Rio is undergoing a period of inclusive growth and integration: a perspective we call here a ‘post‐Third‐World city' narrative of urban renewal. Critics, however, contend that urban officials are harnessing mega‐events (e.g. the 2014 World Cup and the 2016 Olympic Games) to push forward a neoliberal agenda of socially unjust policies benefiting the interests of capital and marginalizing the city's poor and especially its favelas (i.e. the ‘city‐of‐exception' thesis). In this article we explore the insights of these two perspectives and consider why they have grown popular in recent years. Though we side generally with the city‐of‐exception thesis, we argue that important geographic and historical particularities must also be accounted for. Without carefully situating analytical perspectives empirically—in particular, cases in which theoretical models are drawn from European and North American contexts—urban researchers risk concealing more than they reveal in analyses of rapidly developing countries like Brazil. 相似文献

Attendance at sports events continues to rise, as evidenced by increased attendance across a range of sports events in 2014. Despite this, destinations that host live sports events struggle to attract repeat visitors outside scheduled events. This study aims to better understand the relationship between motivation, attachment and loyalty within event tourism. This paper discusses the existing contributions in these areas by drawing on sport and tourism literature and is the first to investigate the relationship across all three constructs. Within this paper, we develop the initial outline of a theoretical model, which depicts these relationships. 相似文献

All Trend Impact Analysis (TIA) algorithms in literature conduct the analysis based on direct estimates provided by experts for the probability of occurrence of an unprecedented event as an input to the algorithm. In this paper, we propose an advanced mechanism to generate more justifiable estimates to the probability of occurrence of an unprecedented event as a function of time with different degrees of severity using Fuzzy Logic. We postulate that in some cases it is better not to estimate the probability of occurrence of an unprecedented event directly; but rather estimate it indirectly via its attributes, using Fuzzy Logic. The core idea of the paper is to customize the generic process of reasoning with Fuzzy Logic by adding the additional step of attributes simulation, as unprecedented events do not occur all of a sudden but rather their occurrence is affected by change in the values of a set of attributes, especially when they reach certain threshold values. 相似文献

AbstractObjective:To compare the demographics, clinical characteristics and resource utilization of patients with bipolar disorder who required frequent psychiatric interventions (FPIs) with those needing fewer interventions in the Duke Healthcare System database between 1999 and 2005.Methods:This retrospective analysis was conducted using electronic medical records of bipolar patients with FPIs, defined as having ≥4 clinically significant events (CSEs) in any 12-month period while in the Duke University Healthcare System. CSEs were composed of emergency room visits, inpatient hospitalizations, or a change in psychotropic medication due to psychiatric symptoms (score ≥4 on the Clinical Global Impressions–Severity scale). Data were compared between patients with and without FPIs.Results:Of 632 patients with bipolar disorder 52.5% were identified as having FPIs. These patients were younger and more often female and African American than those with fewer interventions (p?<?0.01 for all). Patients with FPIs were generally prescribed more psychotropic and non-psychotropic medications, utilized more healthcare resources and experienced more psychiatric co-morbidities than those who did not require FPIs (p?<?0.01 for all).Limitations:These results are from a single healthcare system and may not be generalizable to all patients with bipolar disorder. This analysis was retrospective and relied on availability of adequate information recording and coding of diagnoses by physicians.Conclusions:Patients with bipolar disorder who required FPIs were significantly different from those with fewer clinically defined interventions with respect to their demographic and clinical characteristics and prescribed medications. 相似文献

We study the determinants and the informational role of firms' fixed income conference calls, a unique form of voluntary disclosure that deviates from the traditional multi-purpose firm disclosures intended for all stakeholders. We find that fixed income calls are more likely to be held by firms that have more debt, lack credit ratings or have publicly traded equity, are foreign, or are experiencing losses. In a content analysis using a sample of public firms, we find that these calls discuss debt-equity conflict events, such as share repurchases, to a greater degree relative to a matched sample of earnings conference calls. Finally, we document that credit markets react to these calls, consistent with the calls providing investors new information. Overall, these results are consistent with fixed income calls meeting the differential informational demands of debt versus equity investors. 相似文献

突发事件引起供应链中断或失效而造成商品断供或滞销的情况,对供应链敏捷力提出了新的要求。本文在全面梳理供应链敏捷力理论内涵的基础上,对新冠肺炎疫情期间283家复工复产企业进行调查,实证分析了决定供应链敏捷力的关键要素及其对供应链敏捷力的直接作用以及各要素之间的二阶交互调节作用。研究发现:市场响应对供应链敏捷力的正向促进作用不明显,但有显著的正向调节作用;物流服务则对供应链敏捷力正向促进作用明显,而正向调节作用几乎不存在;协调一致、供应能力、制造能力对供应链敏捷力均起正向作用,其中协调一致最为显著。在突发事件下,协调一致在某种形式上表现为“集中管理”模式,它有助于提高供需匹配的时效性。 相似文献

较之此前的越轨行为,数字经济发展背景下的越轨行为呈现出与数据结合、损害更为严重的特点。基于情感事件理论,文章通过344份企业员工数据,探讨威权型领导对员工越轨行为的作用机制和边界条件,验证了心理契约违背的中介作用,以及个体自尊的调节作用。结果表明:个体自尊既可以调节威权型领导与员工心理契约违背之间的关系,也可以调节心理契约违背与员工越轨行为之间的关系。当个体自尊水平较高时,威权型领导对心理契约违背的正向影响增强,而心理契约违背对员工越轨行为的正向影响减弱。研究结果拓展了对威权型领导影响效应的认识,为理解威权型领导与员工越轨行为的关系提供了新的视角,推动了个体自尊动态研究的发展,并为企业实践提供参考。 相似文献

We introduce a new approach in measuring relative volatility between two markets based on the directional change (DC) method. DC is a data-driven approach for sampling financial market data such that the data are recorded when the price changes have reached a significant amplitude rather than recording data under a predetermined timescale. Under the DC framework, we propose a new concept of DC micro-market relative volatility to evaluate relative volatility between two markets. Unlike the time-series method, micro-market relative volatility redefines the timescale based on the frequency of the observed DC data between the two markets. We show that it is useful for measuring the relative volatility in micro-market activities (high-frequency data). 相似文献
