“后百亿时代”:以文化自律与创新推动电影产业再度振兴

中国电影在赢得100亿票房的业绩后,事实上,正面临着新一轮的文化挑战。突出的问题在于,当下市场严重失序,失去了文化的自律性,逐步形成了一种市场金本位的定势。吸金的思维定势代替了人文的主体性以及艺术的创新与智慧,开启了一种仅以GDP增长为目标的市场方向,造成人文原创性的匮乏以及大片的文化贫血症。针对此种现状,我们应当考虑的不是创造了多少GDP新高,而是今后能否以文化的自律性与艺术的创新精神来提升电影的思想力度与文化品格,在社会审美的意义上实现向现代审美的转换。电影作为文化产品,其固有的精神本源性及其核心价值应是第一位的。因此,我们必须自觉地肩负起时代赋予的文化使命与责任,引导我们的电影产业在与文化的和谐共生中实现再度振兴,为将电影产业做成我们国民经济支柱性产业的伟大目标而努力奋进。     

Quantitative Risk Assessment of the New York State Operated West Valley Radioactive Waste Disposal Area

This article is based on a quantitative risk assessment (QRA) that was performed on a radioactive waste disposal area within the Western New York Nuclear Service Center in western New York State. The QRA results were instrumental in the decision by the New York State Energy Research and Development Authority to support a strategy of in‐place management of the disposal area for another decade. The QRA methodology adopted for this first of a kind application was a scenario‐based approach in the framework of the triplet definition of risk (scenarios, likelihoods, consequences). The measure of risk is the frequency of occurrence of different levels of radiation dose to humans at prescribed locations. The risk from each scenario is determined by (1) the frequency of disruptive events or natural processes that cause a release of radioactive materials from the disposal area; (2) the physical form, quantity, and radionuclide content of the material that is released during each scenario; (3) distribution, dilution, and deposition of the released materials throughout the environment surrounding the disposal area; and (4) public exposure to the distributed material and the accumulated radiation dose from that exposure. The risks of the individual scenarios are assembled into a representation of the risk from the disposal area. In addition to quantifying the total risk to the public, the analysis ranks the importance of each contributing scenario, which facilitates taking corrective actions and implementing effective risk management. Perhaps most importantly, quantification of the uncertainties is an intrinsic part of the risk results. This approach to safety analysis has demonstrated many advantages of applying QRA principles to assessing the risk of facilities involving hazardous materials.     

The effects of correlation among observations on the consistency property of sample variance

It is well known that even when the sample observations are correlated and not normal the sample variance, S² converges in probability to E(S²). But the required sample size for S² to be a consistent estimator of E(S²) is an open question. Some light is shed on this question in this paper. In particular the relation between the rate of convergence and the correlation property of the observations is explored. It is shown that the retardation to the rate of convergence is not appreciable if the correlation is moderate but it can be severe for extreme correlations.

The Special Historical Section of the Journal of American College Health

Abstract

Objective: To identify human papillomavirus (HPV) infection and HPV vaccine–related attitudes among college-aged women and the relationship between HPV vaccine uptake and subsequent sexual behaviors. Methods: PubMed, MEDLINE, CINAHL, and Google Scholar searches were performed from 2006, the date after the first HPV vaccine became available, to present. Results: Of the 13 studies identified, most were cross-sectional. College-aged women saw HPV infection as serious and had positive attitudes toward the HPV vaccine. Barriers (ie, cost, lack of insurance coverage) existed that prevented women from obtaining the vaccine and many women did not see themselves at risk for HPV. The vaccine uptake rate, although increasing, has been slow. Conclusion: College-aged women in the United States may need unbiased information about HPV and HPV vaccine. Studies that focus on risk perception and the relationship between knowledge, attitudes, vaccine uptake, and sexual behaviors are needed to inform interventions and public health programs.     

Alternative Medicine and Herbal Use Among University Students

Abstract

Objective: This study sought to (1) examine perceived stress and resources to cope with stress as predictors of emotional eating during the transition to college and (2) determine whether body mass index (BMI) moderated the emotional eating-stress relationship. Participants: Participants were 97 college freshmen (73% female; BMI: M = 25.3 kg/m², SD = 5.7 kg/m²). Research was conducted in September 2012. Methods: Participants completed the Perceived Stress Scale, Emotional Eating Scale, and Eating and Appraisal Due to Emotions and Stress Questionnaire during the first month of college. Height and weight were measured objectively. Results: BMI moderated the relationship between perceived stress and emotional eating. Higher stress predicted greater emotional eating for the lower BMI groups, but not the highest group. Greater resources to cope with stress predicted lower emotional eating. Conclusions: Greater perceived stress and poorer resources to cope with stress may contribute to emotional eating during the transition to college. The relationship between perceived stress and emotional eating may vary by BMI.     

Principles of Total Quality Management and Their Application to Employee Assistance Programs:

Total quality management (TQM) has been thrust into the psyche of corporate America. TQM is not a new phenomena. Introduced in the early fifties to Japanese managers by an American management expert, it served to make Japan an international economic leader. U.S. companies have generally had little international competition. They now recognize he formidable challenge that quality based companies represent and are striving to replicate these successes. To do so will be to remain competitive. To discount the impact of TQM initiatives could spell economic disaster. Employee assistance program (EAP) management is modeled after American management principles. EAPs are also now having to compete for market share in ways for which they were never prepared. The TQM initiatives currently being implemented in many companies may be applied equally well to EAPs. This article presents an overview of the TQM principles formulated by W. Edwards Derning. The article also attempts to critically analyze some of the areas that have been problematic in EAP management. Further, it examines how TQM initiatives could serve to ameliorate some of these problems and lend additional impetus to the competitiveness of employee assistance programs with other behavioral health care service delivery and cost management programs.     

网络的类市场环境与道德的自发生成

历史及事实皆显示道德在很大程度上沿自生自发的发展路径生成.网络实践较为明显地带来了个人的自主与自由,尤有价值的是文化上的自主性.网络环境是类市场环境,这种类市场环境的特征会逐步促使无数上网个体的自主性的觉醒,进一步确立起个体作为责任主体和道德主体的地位,最终有助于个体道德的生长.网络的类市场环境不仅有助于道德的自发生长,且意外地使自由、自主与道德三者形成了互相促进、相得益彰的关系.已经和正在展现的事实都表明网络的类市场环境让个体的自由、自主与道德获得了前所未有的发展空间,道德因素在网络世界愈发显示出其重要性和力量,并辐射与作用于现实社会.这使我们依然可以对信息时代的道德充满信心.     

Non-Gaussian Ornstein–Uhlenbeck-based models and some of their uses in financial economics

Non-Gaussian processes of Ornstein–Uhlenbeck (OU) type offer the possibility of capturing important distributional deviations from Gaussianity and for flexible modelling of dependence structures. This paper develops this potential, drawing on and extending powerful results from probability theory for applications in statistical analysis. Their power is illustrated by a sustained application of OU processes within the context of finance and econometrics. We construct continuous time stochastic volatility models for financial assets where the volatility processes are superpositions of positive OU processes, and we study these models in relation to financial data and theory.
