覆膜对印刷品颜色影响的计算方法研究

覆膜是印刷品表面整饰加工的重要方法之一,但覆膜对印刷品颜色会产生一定影响,使覆膜前后印刷品的颜色产生一定差别,给印刷过程中颜色控制带来困难。本研究的目的是寻找覆膜对印刷颜色影响的定量规律,以便在印前图像处理和印刷过程中对印刷颜色进行事先控制和修正,使印刷品覆膜后的颜色达到最终的颜色要求。通过对印刷品进行亮光膜和亚光膜的覆膜实验,测量覆膜前后的颜色值,考察颜色变化规律,找出了用CIE XYZ三刺激值进行颜色修正的方法。该修正方法简单易行,可以用于实际生产。     

Hotel service providers’ emotional labor: The antecedents and effects on burnout

The purpose of this study is to examine the antecedents and consequences of two emotional labor strategies (surface and deep acting) in the lodging industry. Variety, duration, and positive display rules are significant predictors of hotel service providers’ deep acting and negative display rules are related to service providers’ surface acting. Employees ohigh in neuroticism are more likely to fake their emotional expressions (surface acting) when dealing with guests and those high in extraversion are more likely to try hard to invoke the appropriate emotions (deep acting). Results further indicate that surface actors are more exhausted and cynical than deep actors and the mediating role of emotional labor between burnout and job and personality characteristics is found to be rather weak. Managerial implications for hotel operators are discussed.     

Cost-effectiveness analysis of atypical long-acting antipsychotics for treating chronic schizophrenia in Finland

Abstract

Objective:

In Finland, regional rates of schizophrenia exceed those in most countries, impacting the healthcare burden. This study determined the cost-effectiveness of long-acting antipsychotic (LAI) drugs paliperidone palmitate (PP-LAI), olanzapine pamoate (OLZ-LAI), and risperidone (RIS-LAI) for chronic schizophrenia.

Method:

This study adapted a decision tree analysis from Norway for the Finnish National Health Service. Country-specific data were sought from the literature and public documents, guided by clinical experts. Costs of health services and products were retrieved from literature sources and current price lists. This simulation study estimated average 1-year costs for treating patients with each LAI, average remission days, rates of hospitalization and emergency room visits and quality-adjusted life-years (QALY).

Results:

PP-LAI was dominant. Its estimated annual average cost was €10,380/patient and was associated with 0.817 QALY; OLZ-LAI cost €12,145 with 0.810 QALY; RIS-LAI cost €12,074 with 0.809 QALY. PP-LAI had the lowest rates of hospitalization, emergency room visits, and relapse days. This analysis was robust against most variations in input values except adherence rates. PP-LAI was dominant over OLZ-LAI and RIS-LAI in 77.8% and 85.9% of simulations, respectively. Limitations include the 1-year time horizon (as opposed to lifetime costs), omission of the costs of adverse events, and the assumption of universal accessibility.

Conclusion:

In Finland, PP-LAI dominated the other LAIs as it was associated with a lower cost and better clinical outcomes.     

医用手套表面残余矿物粉末快速鉴别技术研究

[目的]建立了一种采用XRD粉末衍射快速鉴别医用手套表面残余矿物粉末的方法。[方法]乳胶手套表面残余粉末通过水洗、过滤收集后,采用XRD方法测定了三种不同生产厂家的医用手套表面残余粉末。[结果]三种医用有粉手套的表面残余粉末均为矿物混合物粉末,含有滑石、白云石、菱镁矿、绿泥石、石英和方解石等几种矿物质,从XRD谱图中很容易辨别出矿物粉末和玉米淀粉。[结论]XRD是一种快速、准确的鉴别一次性医用有粉手套表面残余矿物粉末的方法。     

中国存在稳定的消费函数吗——兼谈对E-G两步法的误用

本文指出了目前在很多文献中对E-G两步法误用的地方,其中比较常见的是错用了检验的临界值表.Monte-Carlo试验的结果显示,在不少于三个回归元的情况下,错用临界值表会使我们的检验显著性水平由1%显著提高到60%以上,而5%的显著性水平更是会使我们以近乎于1的概率拒绝不存在协整的零假设.在此基础上本文重新对我国消费函数进行了检验,与现行的结论相反,本文没有发现消费与收入之间有协整关系的证据.

层次分析法(AHP)在商业银行代理国库业务综合评价中的应用

近年来,商业银行通过代理国库业务越来越深入地参与到预算资金的周转过程中,有效提高了资金使用效率,为推动地方经济发展发挥了积极作用。但由于代理国库业务考核无法完全量化,对商业银行代理国库业务缺乏科学的综合评价体系。运用层次分析法原理,分三步构建商业银行代理国库业务综合评级体系,即建立层次结构模型、构造比较矩阵进行计算、一致性检验,实现定量与定性的结合,并最终得出商业银行代理国库业务综合评价结果。     

Emotional labor among police officers: a diary study relating strain,emotional labor,and service performance

Using emotional labor and conservation of resources (COR) theory, this diary study aims to gain insight into the role of daily strain in emotional labor and service performance on a day-to-day basis. Strain was taken into account both as an antecedent (at the start of the work shift), and as a consequence (at the end of the work shift) of emotional labor (surface acting, deep acting) and emotional dissonance. The participants were 53 Dutch police officers who completed a three-day diary questionnaire (i.e. 159 measurement occasions). The results of multilevel analyses showed that, as hypothesized, daily strain at the start of the work shift was positively related to daily surface acting and unrelated to daily deep acting. Furthermore, daily surface acting mediated the relationship between strain at the start of the work shift and (a) service performance and (b) strain at the end of the work shift. Additionally, as predicted, daily surface acting was particularly related to emotional dissonance when strain at the start of the work shift was high.     

DF检验式中联合检验F统计量分布特征

单位根检验同被检验的模型中是否存在常数项、时间趋势项密切相关，针对常数项和时间趋势项及其t统计量的分布特征目前得到了很好的研究，但是相应的联合检验F统计量研究很少，而Hatanka（1996）就提到了该统计量的重要性，并认为有必要对其分布特征进行研究。本文通过蒙特卡罗模拟，分析了DF检验式中联合检验F统计量的分布特征，在此基础上给出了有限样本条件下各检验统计量的响应面函数，从而使得单位根检验进一步完善。
