相变的分类及其特征

本文以吉布斯自由能的偏微商作为相变分类的依据，为相变特征指明了理论根据．并给出了示例．     

清代西江下游经济开发对森林变迁的影响

清代时期，西江下游地区人口激增，农业垦殖向山地深入。随着社会发展，生产生活所需的林、果产品日益增加，人们或直接采伐天然林木，或清除原有的天然林来兴造经济林。同时，这一地区的柴炭、造纸和菌类等农村副业亦得到较大发展。这些经济开发活动对当地的森林变迁产生了重要的影响。我们认为，清代西江下游的森林植被，在清初就已经开始有了较大的破坏和减少，以雍正、乾隆、嘉庆和道光4朝为大。鸦片战争后有所减轻，但一直没有中断。就影响因子而言，清代前期以农业垦殖为主，清代中后期以林木业生产和农村副业为主。     

谢赫“六法”的历史演变

南齐谢赫首次提出了“六法”论，成为中国美术史上影响最深远的美学理论之一，但“六法”并非是“万古不移”的。随着时代的发展和绘画艺术的发展、演变，其具体含义也发生了量或质的变化，“六法间”的相互关系也相应发生了显著的变化。中国画的发展、演变和成熟的过程，也就是“六法”的发展、演变和成熟的过程。二者是同步进行的。     

Prompting Depression Treatment Seeking among Smokers: A Comparison of Participants from Six Countries in an Internet Stop Smoking RCT

Websites containing information and advice about health are increasingly common and popular. It is important to understand whether the material these sites contain can positively influence individual behavior, and whether populations differ in their response to that material. Participants in an international web-based stop smoking randomized controlled trial (RCT) were screened for major depression; participants whose history and/or depression symptoms were deemed of concern were offered one of two prompts (Strong and Mild) to seek treatment, depending on depression history. Participants from 3 predominantly English-speaking and 3 predominantly Spanish-speaking countries were analyzed. Individuals given a Strong prompt were more likely to seek treatment for depression than those given a weak prompt (16.6% vs. 10.2% of previously untreated individuals reported seeking treatment), controlling for symptom level and other variables. Country-specific differences were observed, with participants from South Africa and Spain departing from the common pattern of Strong prompt leading to higher likelihood of treatment seeking. Older age and female gender, but not symptom level predicted higher likelihood of seeking treatment following a prompt. The results suggest that information provided by the health websites can promote help seeking in affected individuals.     

Bayesian inferences related to shifting sequences and two-phase regression

The problem of estimating the switch point in a sequence of independent random variables is studied from a Bayesian viewpoint. Theoretical results and numerical examples are given for the normal sequence and two-phase regression.     

关于可供取舍的可能性原则的一个再思考——在哈里·G.法兰克福的自主性理论框架内

法兰克福在关于相容性问题的讨论当中最引人注目的贡献,就是通过法兰克福反例对可供取舍的可能性原则进行的批驳.但是,可供取舍的可能性原则所表达的那种必要性似乎仍然是我们的一个难以消除的直觉.尝试在法兰克福的自主性理论框架内找到一种对可供取舍的可能性原则的解释,或许能够为我们的这个直觉和法兰克福的自主性理论同时提供支持.     

中国农村居民纯收入聚类分析

应用聚类分析法对我国1992—2006年农村居民人均纯收入进行研究,聚类结果将我国各地区农村居民人均纯收入划分为7大类,而地理因素、政策因素、产业结构因素和收入来源差异因素是各类别农民收入水平存在差异性的重要原因。     

比例失衡、制度变迁与性别和谐--中国妇女参政的新制度主义经济学分析

在倡导人类社会包容性发展的大潮之中，妇女需要提高政治地位以更好的发展，而政治更需要妇女的参与才能促进善政和善治。然而，妇女的政治赋权尚未引起重视，权力尖端女性缺位，公共管理部门女性比例偏低是中国妇女参政不容忽视的问题。问题的根源在于制度上的缺陷，从而将女性置于政治边缘。基于此，提出强制性与诱致性制度变迁相结合的模式，促进政治文明建设与权力领域中的男女平等，实现政治领域中的公平正义。     

中国反倾销条例实体规则研究

通过对中国反倾销条例的研究 ,明确指出 :中国反倾销条例在倾销确认、损害界定等实体规则方面存在诸多问题 ,其规定过于笼统 ,缺乏具体可调整因素的规定 ,可操作性差 ;同时 ,在反规避措施采用和司法审查制度的建立等方面尚属空白。作为发展中国家 ,本着适度保护但又不违背世界贸易组织公平竞争精神的原则 ,处理好前瞻性与阶段性的关系 ,加紧研究制订中国反倾销实施细则 ,及时填补反倾销法律的漏洞 ,充实某些薄弱环节 ,使其更加完备 ,并有效指导我国反倾销实践     

Minimally changed run sequences in factorial experiments

Randomization of run sequences in factorial experiments may result in large number of changes in factor levels which will make the experimentation expensive, time-consuming and difficult. Experiments in which it is difficult to change the levels of factor(s) use of minimally changed run sequences may often be preferable to a random run sequence. In the present paper, we have developed method for obtaining minimally changed run sequences for factorial experiments. The general expression of factor-wise number of level changes for the developed minimally changed run sequences has also been obtained. A relationship has been established between the time count effect of a lower order factorial with minimally changed run sequences and that of a higher order factorial with minimally changed run sequences obtained through the lower order minimally changed run sequences. For providing a readymade solution to the end users, a SAS macro has also been developed for generating these minimally changed run sequences along with its parameters.
