Hotel job burnout: The role of personality characteristics

In hospitality and tourism academia, most research focuses on the work domain as a major source of hospitality job stress, with little attention given to employee characteristics. This study examines the effect of the Big Five personality dimensions (extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience) on hotel employees’ job burnout. After controlling for two commonly known job burnout antecedents (autonomy and quantitative workload), study results indicate that personality attributes explain significant proportions of three job burnout factors. The most noteworthy finding is the predictability of the agreeableness trait in hotel employees’ job burnout. Because of the mixed results reported on the relationship between this trait and job stress in other disciplines, more vigorous future research is recommended to validate the value of this personality to the hospitality industry.

Employment Quota System and Labour Market Outcomes of Individuals with Disabilities: Empirical Evidence from South Korea

To date, only a few studies have attempted to evaluate the effectiveness of disability employment quota systems using structural changes in policies. This study exploits the structural changes in South Korea's disability employment quota system that took place in 2004 and 2006 to expand the current disability policy evaluation literature. We separate the effect of these changes in the quota system into their effect on the probability of labour force participation and their effect on the probability of employment (after controlling for selection into the labour market). We also study the extent to which the changes – which included increasing the number of employers covered by the quota system, the number of jobs available to individuals with disabilities and the financial incentives for employing individuals with disabilities – have affected job satisfaction among individuals with disabilities. Our results suggest that the changes in the quota system may have increased labour force participation but have had a limited positive impact on the probability of employment among people with disabilities in South Korea. Further, compulsory hiring and expanded opportunities have not substantially affected the level of job satisfaction observed among employees with disabilities relative to their non‐disabled counterparts.     

内部人交易与持续经营审计意见——来自财务困境类上市公司的经验证据

股改完成后内部人交易日益常态化,内部人交易受到监管层和市场各方的关注。为了降低事后被查处的可能性,发生内部人交易的财务困境类上市公司可能会要求审计师签发更好的审计意见。基于2007至2013年上市公司内部人交易数据,研究发现:财务困境类上市公司内部人交易与持续经营审计意见显著负相关;审计师对上市公司经济依赖的程度越高,内部人卖出交易与持续经营审计意见负相关关系越显著。更进一步地,内部人交易与持续经营审计意见负相关的关系主要体现在股权制衡度较低、分析师跟进数量较少以及机构投资者持股比例较低的上市公司,表明上述公司治理机制有效地遏制了财务困境类上市公司发生内部人交易后胁迫审计师签发干净审计报告的行为。     

Does financial connectedness predict crises?

The global financial crisis has reignited interest in models of crisis prediction. It has also raised the question whether financial interconnectedness—a possible source of systemic risk—can serve as an early warning indicator of crises. In this paper, we examine the ability of connectedness in the global network of financial linkages to predict systemic banking crises during the 1978–2010 period. Our results indicate that increases in a country’s own connectedness and decreases in its neighbours’ connectedness are associated with a higher probability of banking crises after controlling for macroeconomic fundamentals. Our findings suggest that financial interconnectedness has early warning potential, especially for the 2007–2010 wave of systemic banking crises.     

知识产权保护、FDI与研发创新全要素生产率——基于中国区域高技术产业的实证研究

运用DEA模型的Malmquist指数法对2000~2012年我国区域高技术产业研发创新全要素生产率(TFP)进行测算,并将知识产权保护、FDI与研发创新TFP纳入统一的框架下进行系统分析,考察知识产权保护、FDI对我国高技术产业研发创新TFP及其分解指数的影响。研究结果表明:我国高技术产业研发创新TFP年均增长6.3%,主要动力为技术进步;我国各区域的知识产权保护水平差异显著;回归结果显示:对于我国高技术产业研发创新TFP而言,知识产权保护有着显著的促进作用,FDI表现出显著的负溢出效应,二者的交互作用也存在显著正向影响。     

一株耐铜细菌TLSB_2-K的鉴定及其铜吸附能力

通过形态观察、革兰氏染色和16Sr DNA序列比对,对前期分离的菌株TLSB2-K进行了鉴定,并采用振荡培养法,探讨了温度、p H值和渗透压对菌株生长的影响,以及铜胁迫下菌株对铜的耐性及吸附能力。结果表明,TLSB2-K属于芽孢杆菌属,其最适生长条件为:温度27℃、p H值7、渗透压1.1%Na Cl。铜胁迫下菌株生长周期缩短。铜浓度在100~500 mg/L的范围内,菌体生长良好,铜浓度为100 mg/L时胁迫培养25 h,菌体铜含量为1 253.4 mg/kg;铜浓度为200 mg/L和300 mg/L时胁迫培养30 h,菌体铜含量分别达到2 087.2 mg/kg和2 188.4 mg/kg;菌株的最高铜耐受浓度为700 mg/L。实验结果证实,菌株TLSB2-K具有较强的铜耐性和较高的铜吸附能力,其具有重要的理论研究和工程应用价值。     

External Corporate Governance and Misreporting

This study investigates how external corporate governance provisions, specifically statutory and corporate charter provisions that limit direct shareholder participation in the governance process, affect the likelihood of an accounting restatement. The analysis indicates that strong external governance (fewer restrictions on shareholder participation) is associated with a relatively low incidence of accounting restatements. The effect of external governance is incremental to that of internal governance, which is considered as provisions that foster effective board oversight of management. Such evidence supports the premise that shareholder participation improves financial reporting quality.     

浅析保险投资的风险控制——以保险公司的视角

中国保监会于2012年颁布了10项关于保险行业投资的新政,这表明我国正逐步放宽对保险业投资的政策管理,鼓励保险公司积极拓宽自身的投资渠道,同时也降低了对保险公司投资比例的要求,这也使得我国保险公司资金投资将面临更多的风险,因此,要拓宽投资渠道,进行投资组合;成立保险投资基金,加大对基金的管理力度;第三方托管养老产业,联合银行机构风险共担;加强风险管理机制,完善激励和约束制度.
