以边境口岸辐射城镇化:西南边境地区发展模式研究

边境地区因地制宜地推进城镇化,具有"富民、兴边、强国、睦邻"的重大现实意义。迅速兴起的互市贸易、口岸经济、跨境经济表明,以边境口岸辐射城镇化可以促使生产要素整合和人口转移,形成人口规模聚集,培育互市型、口岸型和跨境经济合作型城镇,呈现三个层次的沿边发展模式体系。西南边境地区应当挖掘各自的优势,促进各种要素的合理流动和高效聚集,形成优势互补,从而推进西南边境地区的综合发展。     

《中华日报》两阶段之始末

《中华日报》创办之时,正逢“九·一八”“一·二八”事变之后,国内政治纷争愈演愈烈的重要时间节点。汪精卫为了独树一帜,扩大政治影响,需要有一个发声渠道。《中华日报》的系统化及普遍联系的新闻编辑思路,在当时较之它报具有一定的先进性。“左联”作家、左翼经济学人与《中华日报》合作办副刊,是利用《中华日报》“改组派”色彩中的某些相容性,为自己策略性地找到了可以暂时容身之处。汪精卫另立政权(或曰投敌),某种程度上就是国民党的派系政治在特殊历史时期的极端化,而《中华日报》则与之如影随形,是派系政治极端化的记录者。《中华日报》是日伪合谋贩售所谓“和平建国”“中日亲善”“东亚共荣”政治骗局的大招幌,更是掩盖日本军国主义侵华罪行的遮羞布,在中国新闻史上留下了耻辱的一笔。     

Testing Goodness of Fit for Parametric Families of Copulas—Application to Financial Data

ABSTRACT

This article suggests a chi-square test of fit for parametric families of bivariate copulas. The marginal distribution functions are assumed to be unknown and are estimated by their empirical counterparts. Therefore, the standard asymptotic theory of the test is not applicable, but we derive a rule for the determination of the appropriate degrees of freedom in the asymptotic chi-square distribution. The behavior of the test under H ₀ and for selected alternatives is investigated by Monte Carlo simulation. The test is applied to investigate the dependence structure of daily German asset returns. It turns out that the Gauss copula is inappropriate to describe the dependencies in the data. A t _ν-copula with low degrees of freedom performs better.

Fundamentals of Health Risk Assessment. Use,Derivation, Validity and Limitations of Safety Indices

We investigated the way results of human health risk assessments are used, and the theory used to describe those methods, sometimes called the NAS paradigm. Contrary to a key tenet of that theory, current methods have strictly limited utility. The characterizations now considered standard, Safety Indices such as Acceptable Daily Intake, Reference Dose, and so on, usefully inform only decisions that require a choice between two policy alternatives (e.g., approve a food additive or not), decided solely on the basis of a finding of safety. Risk is characterized as the quotient of one of these Safety Indices divided by an estimate of exposure: a quotient greater than one implies that the situation may be considered safe. Such decisions are very widespread, both in the U. S. federal government and elsewhere. No current method is universal; different policies lead to different practices, for example, in California's Proposition 65, where statutory provisions specify some practices. Further, an important kind of human health risk assessment is not recognized by this theory: this kind characterizes risk as likelihood of harm, given estimates of exposure consequent to various decision choices. Likelihood estimates are necessary whenever decision makers have many possible decision choices and must weigh more than two societal values, such as in EPA's implementation of conventional air pollutants. These estimates can not be derived using current methods; different methods are needed. Our analysis suggests changes needed in both the theory and practice of human health risk assessment, and how what is done is depicted.

Stress Spillover and Crossover in Same-Sex Couples: Concurrent and Lagged Daily Effects

ABSTRACT

A growing body of literature on romantic relationships demonstrates associations between daily stress and relationship quality; however, this research has largely focused on heterosexual couples. Whereas all couples may experience common external stressors originating outside the relationship (e.g., work and finances), sexual-minority couples may also experience unique stressors due to their sexual orientation (e.g., discrimination or harassment). To address the dearth of literature on the daily experience of stress in same-sex relationships, we examine concurrent (same-day) and lagged (next-day) effects of common external and sexual-minority stressors on relationship quality using 14-day daily diaries from 81 same-sex couples. In doing so, we identify the types of external stress most likely to spill over into the relationship, as well as those vulnerable to crossing over from one partner to the other. We further examine whether the effects are proximal (concurrent) or carry over from one day to the next (lagged). Common external stress was negatively associated with same-day actor and partner relationship quality. Sexual-minority stress demonstrated lagged effects for actor relationship quality, but only for men. Implications for the proximal impact of common external stress and the lagged effects of sexual-minority stress, specifically for men, on relationship quality are discussed.
