人工收集和整理2012—2018年在中国市场上映的首轮院线电影信息数据,构建电影需求的嵌套logit回归模型,以新冠肺炎疫情为准自然实验,来量化突发公共事件对电影行业复产复工的影响。结果显示:第一,关于上映时间选择,在恢复营业后,如果所有因为疫情尚未上映的电影选择顺延上映能有效避免过度竞争的局面。第二,关于上映节奏控制,控制好未定档电影的上映节奏,保持适当的竞争能促进经济效益提升。其中,从11月份开始以每周两部的频率上映未定档电影的经济效益最佳。第三,关于上映方式选择,与线下播放相比,疫情期间选择线上播放能及时收回成本并有利于经济收益最大化的实现。研究结论为电影行业制定复产复工策略提供依据,为未来应对突发公共卫生事件提供参考。  相似文献

The COVID-19 crisis has fundamentally changed how many businesses operate and connect with their customers. Previously unheard-of government restrictions and sheltering-in-place requirements forced most professional services to transition to remote delivery methods (e.g., email, telephone, video consults, Shopify storefronts). Providers of low-touch services (e.g., lawyers, accountants) naturally lent themselves to remote delivery; however, those that offer high-touch services, particularly those in healthcare (e.g., doctors, chiropractors, physical therapists), experienced a drastic change in working conditions when going virtual. Despite a long history of resistance to virtual delivery, the pandemic created an unprecedented incentive for these high-touch professionals to experiment with underutilized care models such as telehealth: the provision of healthcare services remotely using telecommunications technologies. We examine the rapid adoption of telehealth during COVID-19 through the coming together or convergence of previously unrelated technologies, spaces, and practices. Our analysis reveals opportunities and challenges associated with going hands-off that apply to many other professionals providing high-trust services. Specifically, we offer nine guiding principles for building and protecting cognitive and affective trust in virtual and hybrid delivery models. This is important given the pace of compounding technology convergences that lie ahead for service professionals.  相似文献

This study examines how corporate social responsibility (CSR) participation affects organizational citizenship behavior (OCB) through meaningful work. This work is significant for three reasons: the joint examination of CSR, meaningful work, and OCB is novel; the comparative effects of CSR perception versus CSR participation have not been examined previously; and this is the first examination of such relationships for different generations of employees. Data from 245 employees of four-star hotels were analyzed using a partial least squares structural equation modelling (PLS-SEM) approach and multigroup analysis (MGA). Results reveal that CSR participation has a strong influence over work-related outcomes. The strongest effect of CSR participation on helping behavior is in Generation Y whereas CSR perception has a strong indirect effect on helping behavior through meaningful work in Generation X. These findings offer managerial implications to hotel managers on how best to manage generational differences in predicting helping behavior at workplace.  相似文献

This paper analyzes Germany's unusual labor market experience during the Great Recession. We estimate a general equilibrium model with a detailed labor market block for post-unification Germany. This allows us to disentangle the role of institutions (short-time work, government spending rules) and shocks (aggregate, labor market, and policy shocks) and to perform counterfactual exercises. We identify positive labor market performance shocks (likely caused by labor market reforms) as the key driver for the “German labor market miracle” during the Great Recession.  相似文献

This article is a review paper, which examines the place of gender in hospitality research and education and discusses the significance of hospitality for women's employment and entrepreneurship opportunities. The paper’s main purpose, however, is to speculate on the future of hospitality gender research and women’s employment prospects in the industry. It suggests that, despite the emergence of gender perspectives in hospitality research and the recent rise of popular feminism in response to high-profile sexual harassment cases and a well-publicised gender pay gap, gender still does not occupy mainstream territory in the field. The paper stresses the continued missed opportunities of neglecting female talent and calls on female and male leaders to shape a gender-just future in hospitality study and practice by mentoring and holding hierarchies to account. The paper identifies AI and robotics and sexual exploitation and harassment as two areas in which hospitality gender scholars could lead scholarship and policy debates on gendered human experiences.  相似文献

针对宽带网络波形(Wideband Networking Waveform,WNW)的多信道二维时频资源,以减小网络资源浪费为优化目标,提出了一种基于定价策略的时隙选择方法(Pricing Strategy Based Slot Selection,PSSS)。该方法通过接纳控制保障资源分配的公平性,采用对偶优化建模与椭圆搜索法实现最优的时隙选择。理论分析证明该方法能够在多项式级别时间复杂度内搜索到时隙选择的最优解。仿真结果表明,提出的PSSS算法通过较低资源浪费获得了较低的容量冗余度,能够有效地解决WNW多信道网络的时隙选择问题。  相似文献

The increasing number of tourist in Bhutan demands for more high-quality hotels to provide better services to guests. The objectives of the study are, (1) to assess the current training provided to the hotel employees; (2) to evaluate the training gap concerning training design and; (3) to examine relationship between the training factors affecting the training effectiveness in Bhutanese hotel industry. Findings showed mismatch of training provided to employees resulting in poor quality of service. Negative score was found between the importance and satisfaction level of hotel employees on contents of training design. However the results showed positive relationship between the training factors and training effectiveness, work environment has strong influence.  相似文献

This article argues that copyright is a systemic marketplace icon because of the breadth of its effects on market operations. Copyright determines how intellectual property rights for creative work are allocated between the different actors involved in production and consumption, and must balance the civic priority of public access to creative work with the market-driven principle of rewarding private interests for their effort. This duality tends to polarise opinion about its implementation by rights holders, because very different ideological assumptions underpin civic and market objectives. Copyright discourses reveal how these ideological struggles play out among interested parties, who use the concept of copyright to make arguments about how markets should be structured, how creative work should be exchanged, and how consumers should behave. In the process, copyright is constructed, explained, branded and promoted as an object to which market actors must orient themselves if they wish to conduct themselves appropriately, and as a rationale for material changes to market structures. At the same time, copyright discourses reveal the implications of copyright, which invoke both the market and democracy, for the quality of democracy, the circulation of creativity, and the availability of public knowledge, and help explain why ideological struggles over copyright are so difficult to resolve.  相似文献

ABSTRACT

This study explores how religious and ethnic norms and gender relations interact across the domestic and public spheres of work in rural China's minority-concentrated regions. It focuses on the roles that childcare and household composition play in the employment decisions of prime-age married individuals of Muslim and non-Muslim ethnicity. Using the 2012 China Household Ethnicity Survey (CHES), the study finds that children generally decrease women's likelihood of employment outside the home and increase men's. The gender gap in the probability of off-farm employment is larger for those of Muslim ethnicity. Non-Muslim parents of sons are more likely to migrate for employment than parents of daughters. The presence of women of grandparent age (46–70) universally facilitates labor migration. Men of grandparent age tend to increase only the probability that non-Muslim parents migrate for employment. Additional adult male household members reduce the likelihood that women of Muslim ethnicity have off-farm employment.  相似文献
