试析近年来朝鲜半岛核问题的演化以及中国的作为

近几年来,朝鲜半岛无核化进程出现严重逆转,六方会谈一直陷入沉寂.半岛核问题恶化的一个主要原因是朝鲜国内的权力过渡引发了各方政策关注点的再调整.朝鲜的核能力在过去几年里取得了一些重大进展,加深了国际社会的忧虑.为了推动六方会谈重启,中国做出了种种努力,但要成功实现早日复谈,仍需要美朝展示灵活性,发挥主动性,彼此合作并与其他各方共同努力,使半岛核问题重新驶回正确的轨道.     

How Much Internalization of Nuclear Risk Through Liability Insurance?

An important source of conflict surrounding nuclear energy is that with a very small probability, a large-scale nuclear accident may occur. One way to internalize the associated financial risks is through mandating nuclear operators to have liability insurance. This paper presents estimates of consumers' willingness to pay for increased financial security provided by an extension of coverage, based on the 'stated choice' approach. A Swiss citizen with median characteristics may be willing to pay 0.14 US cents per kwh to increase coverage beyond the current CHF 0.7 billion (bn.) (US$ 0.47 bn.). Marginal willingness to pay declines with higher coverage but exceeds marginal cost at least up to CHF 4 bn.(US$ 2.7 bn.). An extension of nuclear liability insurance coverage therefore may be efficiency-enhancing.     

核电企业核安全文化主动涵化评价方法的研究

核安全文化是核电企业文化的重要组成部分,文章主要结合我国《核安全文化政策声明》中的要求研究核安全文化的主动涵化过程,并分析核安全文化的主要特征,提出核安全文化主动涵化评价指标和评价方法(ZXW法),这对核电企业的核安全文化建设具有一定的指导作用。     

核威慑的伦理问题域及其表现分析

核威慑问题涉及军事、政治、国际关系、科技、经济、文化、法律等领域,是一个极为敏感又牵涉面广且同人类的和平、安全、幸福以及身家性命密切关联的问题丛。核威慑关乎生命价值和尊严问题,关涉政治权利的正当性问题、传统战争伦理规范的适应性问题、工具理性与价值理性的冲突问题,涉及主权、人权与国际正义的困境问题。核威慑的伦理问题错综复杂且牵涉面广,人类迫切需要发展核威慑伦理理论,提升自身对核武器的实践理性能力。     

大力发展湖南省核能产业

核能产业是湖南省重点发展的战略性新兴产业,大力发展核能产业,对改善我省能源结构、加快产业结构升级、促进“四化两型”社会建设有着重要的意义。从国内外核能产业发展来看内陆核电比例占60％以上,我国核电建设突飞猛进;湖南省为经济大省,又是核工业大省,具有核电基础优势和安全的地质条件。因此,应整合优势资源,打造国家级核能产业园;支持内陆核电项目重启,增强新型工业化的推动力;促进核能产业全面发展,提升核工业大省地位;加大人才培养投入,构建核专业人才培养体系;大力宣传核电科普知识,加强核安全与公众的沟通等以加快湖南省核能产业发展。

Testing hypotheses about the common mean of two normal populations

Two simple tests which allow for unequal sample sizes are considered for testing hypothesis for the common mean of two normal populations. The first test is an exact test of size a based on two available t-statistics based on single samples made exact through random allocation of α among the two available t-tests. The test statistic of the second test is a weighted average of two available t-statistics with random weights. It is shown that the first test is more efficient than the available two t-tests with respect to Bahadur asymptotic relative efficiency. It is also shown that the null distribution of the test statistic in the second test, which is similar to the one based on the normalized Graybill-Deal test statistic, converges to a standard normal distribution. Finally, we compare the small sample properties of these tests, those given in Zhou and Mat hew (1993), and some tests given in Cohen and Sackrowitz (1984) in a simulation study. In this study, we find that the second test performs better than the tests given in Zhou and Mathew (1993) and is comparable to the ones given in Cohen and Sackrowitz (1984) with respect to power..     

Using the integrative model of behavioral prediction to understand college students’ STI testing beliefs,intentions, and behaviors

ABSTRACT

Objectives: To identify salient behavioral determinants related to STI testing among college students by testing a model based on the integrative model of behavioral (IMBP) prediction. Participants: 265 undergraduate students from a large university in the Southeastern US. Methods:Formative and survey research to test an IMBP-based model that explores the relationships between determinants and STI testing intention and behavior. Results: of path analyses supported a model in which attitudinal beliefs predicted intention and intention predicted behavior. Normative beliefs and behavioral control beliefs were not significant in the model; however, select individual normative and control beliefs were significantly correlated with intention and behavior. Conclusions: Attitudinal beliefs are the strongest predictor of STI testing intention and behavior. Future efforts to increase STI testing rates should identify and target salient attitudinal beliefs.
