掺硅二氧化钛复合薄膜超亲水性研究

采用溶胶-凝胶法在普通载玻片上制备TiO2-SiO2复合薄膜,文章研究了SiO2添加量对润湿角的影响。结果表明:通过在TiO2薄膜中加入SiO2,能显著降低薄膜的润湿角,超亲水性状态可以保持很长时间;当SiO2添加量为30%时,在紫外光照1h,薄膜的润湿角接近0°,光催化活性最佳。     

Accounting for optimism and pessimism in expected utility

We provide a preference foundation for decision under risk resulting in a model where probability weighting is linear as long as the corresponding probabilities are not extreme (i.e., 0 or 1). This way, most of the elegance and mathematical tractability of expected utility is maintained and also much of its normative foundation. Yet, the new model can accommodate the extreme sensitivity towards changes from 0 to almost impossible and from almost certain to 1 that has widely been documented in the experimental literature. The model can be viewed as “expected utility with the best and worst in mind” as suggested by Chateauneuf, Eichberger and Grant (Chateauneuf, Alain, Eichberger, Jürgen, Grant, Simon, 2007. Choice under uncertainty with the best and worst in mind: NEO-Additive capacities. Journal of Economic Theory 137, 538–567) or, following our preference foundation, interpreted as “expected utility with consistent optimism and pessimism”.

Measuring the Quality of Life in the Workplace （QLW） Through Job Diagnostic Survey （JDS）： Comparative Study on Two Legal Nature Differentiated Organizations

The article presents a theoretical-empirical reflection about concepts, models, and practices of Quality of Life at Work （QLW） in organizations of different legal nature. The initial proposition of the research suggested that private organizations, that are more susceptible to competitive pressures in the market for resources and the uncertainties regarding the employability tend to have worse indicators of QLW than the public organizations that exhibit greater control over their influx of resources and greater stability in jobs that are offered. The literature review included the concepts and models of QLW as well as the characteristics and application methodology of the Job Diagnostic Survey （JDS）, and your score on Task Motivational Potential （TMP）, as instruments of evaluating the dimensional indicators of QLW in organizations. In methodological terms, we proceeded to a multiple case study comparative, supported by the application of the reduced version of JDS, through its questionnaire that has already been validated in previous studies in two organizations, a private foundation supporting university and a public company of electricity supply, both located in the State of Amazonas-Brazil. The research findings using the JDS instrument indicated failed to detect significant differences between the scores of TMP between the two organizations, nor any robust correlation between their respective legal personalities and environments of institutional performance. Nevertheless, the small differences found suggest a framework of indicators of QLW slightly more favorable to the foundation of university support.
