Effects of service orientation on job embeddedness in hotel industry

This research aims to develop and analyze a model that depicts work engagement (WE) as a mediator of the relationship between job embeddedness and service orientation. Specifically, the model examines external environmental factors (EEFs) as moderator of the effects of service orientation and job embeddedness in the hospitality industry. All data used for this study were gathered in Iran from hotels frontline employees with a two-weeks’ time lag. These relationships mentioned above were analyzed using AMOS 22.0. It was discovered in the results that WE was indeed a partial mediator and that EEFs indeed moderated the effects of service orientation on job embeddedness with adequate empirical support. The implications of the findings for the managers, the study limitations, and future research recommendations were also discussed.

新冠肺炎疫情发生以来,浙江省金融系统积极响应,快速落实,对内严格疫情排查防控,对外做实金融服务保障,及时出台疫情防控金融服务政策措施,精准用好专项再贷款资金,主动对接疫情防控领域重点企业生产资金需求,全力构建本外币政策绿色通道,充分发挥金融在疫情防控工作中的重要作用。当前,我省疫情防控工作已经进入新阶段,全省金融系统要进一步巩固阶段性成果,切实帮扶受疫情影响的困难企业,全面做好复工复产金融服务,坚决打赢疫情防控阻击战。     

跳跃随机波动的阈值模型风险值的贝叶斯估计

文章基于一类跳跃随机波动的阈值模型风险值估计贝叶斯分析,在给定先验分布下,以马尔科夫链蒙特卡洛方法估计模型中的未知参数,并给出了MCMC模拟算法,进而讨论了风险值的预测。根据模拟结果,我们得知,如果没有考虑金融时间序列的外生冲击导致的跳跃行为,将会高估风险值,因此考虑跳跃行为后,将增加风险值估计的精度。     

国内外饭店职业经理人研究综述

我国对饭店职业经理人的研究从理论到实践两个方面都滞后于市场经济发达国家。中外职业经理人出现的经济背景和社会条件不同,研究的关注点差别较多。国外的研究最早关注于经理人角色、继而关注总经理的管理能力、经理人职业路径、经理人与雇主关系、经理人薪酬体系和经理人胜任力模型等。国内的研究则关注于饭店职业经理人界定、能力与素质、市场化问题、队伍建设与发展,近两年才出现饭店职业经理人角色研究。同时,在研究方法上还存在着以宏观研究为主,微观研究不足,定性研究较多,定量研究不够,研究方法单一,缺少对相关理论的系统研究和集合的问题。国内外研究者在研究内容、层次、视角上的差异,其实质反映了饭店职业经理人生存与发展的环境差异,即市场经济成熟度的差异。     

Gender, emotion and power in work relationships

We offer a theoretical account of how gender and emotion combine to influence the development of power in work relationships. We document the profound impact gender has on the display, perception and evaluation of emotion in the workplace. We illustrate the reciprocal relationship between emotion and power, and identify cycles of powerlessness that prevent women from developing and leveraging power in their work relationships. By exploring the nexus of gender, emotion and power in work relationships, we offer new insights into how the gendering of emotion creates and perpetuates gender differences in power in organizations. Implications for research and practice are offered.     

基于EGARCH模型和Bootstrap方法的在险价值度量

针对孤立使用传统的历史模拟法及GARCH类模型进行风险分析的不足,把EGARCH参数模型与Boostrap非参数方法结合起来,给出了基于EGARCH模型和Bootstrap的VaR测度的半参数方法。实证结果表明,基于EGARCH模型和Bootstrap的VaR度量方法比传统的历史模拟法计算的效果更好。     

夸大还是低估——基于不同来源数据的出生性别比水平分析

中国的出生性别比从上世纪80年代以来出现持续偏高的现象,我国目前公布的人口出生性别比的准确性成为各界争论的焦点。通过对最新的公民身份信息数据、历年全国在校小学生人数统计数据、2000年第五次人口普查数据和2005年1%人口抽样调查数据等几组不同来源的出生性别比数据进行质量评估、相互比对和分析,可以发现由于低年龄组女孩漏报、瞒报的原因,我国目前公布的人口出生性别比略有夸大,但是从程度上而言夸大不多,大概在2-3个百分点左右。即使扣除了这2-3个百分点的影响,我国的出生性别比水平依然严重偏高,形势依然非常严峻。     

俯首甘为孺子牛——辅导员工作经验浅谈

学生是民族的希望,是祖国的未来。高校是培养社会主义合格建设者和可靠接班人的摇篮,是当今世界综合国力竞争的前沿阵地。政治辅导员作为高校学生日常思想政治教育和管理工作的组织者、实施者和引导者,担负着为国家和社会输送人才的重任。我们要用"俯首甘为孺子牛"的精神,默默奉献,善于创新,努力完成这个光荣的使命。

Forecasting value at risk and expected shortfall with mixed data sampling

I propose applying the Mixed Data Sampling (MIDAS) framework to forecast Value at Risk (VaR) and Expected shortfall (ES). The new methods exploit the serial dependence on short-horizon returns to directly forecast the tail dynamics of the desired horizon. I perform a comprehensive comparison of out-of-sample VaR and ES forecasts with established models for a wide range of financial assets and backtests. The MIDAS-based models significantly outperform traditional GARCH-based forecasts and alternative conditional quantile specifications, especially in terms of multi-day forecast horizons. My analysis advocates models that feature asymmetric conditional quantiles and the use of the Asymmetric Laplace density to jointly estimate VaR and ES.
