The Relationships Between Emotional Intelligence,Job Stress,and Quality of Life Among Tour Guides

Considerable evidence supports the notion that higher job stress is associated with lower quality of life (QOL), which is an increasingly common indicator to assess an individual's general health status, mental health and well-being. Those with higher emotional intelligence (EI) levels are more aware of their emotions and have more effective coping strategies to deal with stress-related emotions, all of which lead to higher levels of well-being. The purpose of this study is, therefore, to explore the relationships between EI, job stress and QOL among tour guides, who significantly influence tourists' impressions of a destination. The obtained results indicated that EI was inversely correlated with occupational stress and positively associated with QOL, and a negative link was seen between job stress and QOL. In practice, the results can provide information for developing interventions to enhance tour guides' competencies of EI and stress management, which result in higher levels of QOL.     

Oil windfall,public spending and price stability: modelling inflation in Chad

This article examines the determinants of inflation in Chad using quarterly data from 1983:Q1 to 2009:Q3. The analysis is based on a single-equation model, completed by a Structural Vector Autoregression (SVAR) model to capture inflation persistence. The results show that the main determinants of inflation in Chad are rainfall, foreign prices, exchange rate movements and particularly public spending, which soared following the onset of oil production in 2003. The effects of rainfall shocks and changes in foreign prices on inflation persist during six quarters. Changes in public spending and the nominal exchange rate affect inflation during three and four quarters, respectively.     

Financial stress,economic activity and monetary policy in the ASEAN-5 economies

This article uses a structural vector autoregression approach to analyse the impact of financial stress on the economy and the relationship between monetary policy and financial stress in the ASEAN-5 economies (Indonesia, Malaysia, Philippines, Singapore and Thailand). We find that an increase in financial stress leads to tighter credit conditions and lower economic activity in all five countries. The estimated impact on the real economy displays an initial rapid decline followed by a gradual dissipation. In Malaysia, the Philippines and Thailand, the central banks tend to reduce policy interest rates (IRs) when financial stress increases, although there is substantial cross-country variation in the magnitude and time dynamics. The lower policy IRs are found to have little significant effects in lowering financial stress, but are still effective in stimulating economic activity through other channels. These findings imply that easing monetary policy is likely necessary but insufficient to address growth slowdowns associated with financial stress. Monetary easing should instead be complemented with other policy measures which are targeted at restoring financial stress to normal levels.

高校学报编辑的工作应激及应对策略

影响我国高校学报编辑心理状态的主要因素来自于工作应激源。个体在高应激状态下如果缺乏良好的应对方式,心理受损的危险程度是普通人群的两倍,而成熟的应对方式有助于工作者积极理性地面对工作应激。根据CPT理论,抵抗工作应激的措施,一方面可采取降低对应激源危险性的评估,另一方面应重视应对方法的了解及应用。全面提升高校学报编辑的心理素质,需要学报出版单位和编辑个人采取多种措施,掌握更多专业的、科学的工作应激应对资源。     

宏观经济因素、信用风险与压力测试

通过文献综述发现宏观经济因素波动是导致银行产生信用风险的重要原因之一。美国金融危机以来,我国经济面临的最主要问题是进出口大幅下降,我国商业银行在这样的宏观经济发生重大变动的情况下面临怎样的信用风险?本文在评介现有的宏观压力测试方法的基础上,提出并用实证证明利用投入产出模型建立宏观压力测试方法可以对出口大幅下降展开有效的行业内生影响分析并分解到每一个企业身上,从而为银行分析贷款不良率,管控信用风险提供直接的参考依据。     

强声波激励下转子叶片的振动分析

声场分析是一类比较复杂的场分析问题。本文基于有限元法,建立了高强声波辐射场中某型转子叶片振动分析的有限元模型,并分别采用球面声波辐射,柱面声波辐射,平面声波辐射和均布声压等作用形式比较了叶片上振动的应力和声压分布。计算了3种叶片,数值计算的结果都与实验结果比较一致,定量揭示了高强声波对转子叶片的影响程度。     

Associations between workers' health,and non-standard hours and insecurity: the case of home care workers in Ontario,Canada

This article examines associations between home care workers' health, and non-standard hours and insecurity. Health refers to symptoms of stress and musculoskeletal disorders (MSDs), non-standard hours refer to part-time and casual hours, and insecurity refers to job and employability insecurity. Data come from our 2002 survey of 532 home care workers (nurses, therapists and personal support workers) in a medium-sized city in Ontario, Canada. Path analysis regression results for the conceptual model show that (1) part-time and casual hours and job insecurity are positively and significantly associated with symptoms of stress, (2) the associations between part-time and casual hours and MSDs are mediated by symptoms of stress, and (3) job and employability insecurity are directly associated with MSDs. Results provide evidence that non-standard hours and insecurity must be addressed in order to improve home care workers' health. We show the detrimental effects of non-standard hours and insecurity on workers' health, and the results have implications for employers, human resource managers, trade unionists and government policy-makers.     

特载作用下的水泥混凝土道面承载能力分析

对于特殊载荷作用下的道面承载能力验算,水泥混凝土路面设计规范中基于标准轴载和当量圆模式的荷载应力分析方法不再适用,本文采用弹性层状体系假定的数值计算方法能较好完成特载作用下的应力分析;在板体温度应力计算方面,规范中计算方法依然适用,将数值计算的荷载应力分析和规范计算的温度应力分析结果叠加,即为水泥混凝土道板整体应力分析。研究表明:1)道面一、二、三承载力满足特载要求;2)道面四不能满足特载要求,但加设钢垫板后满足承载要求,加设钢垫板后道板应力改善明显,表明加设钢垫板是一种简便易行且效果明显的改善方案。文章最后提出了实施细节要求。
