老庄哲学中的科学思想

老庄哲学把对自然现象、人类生存状况及生产经验的观察、研究,作为切入点,建立起了道家的自然观,展示了老庄在自然科学方面最初的理论自觉。老庄坚持"道"生万物说、道为宇宙万物的本体的理论;庄子提出了生物起源、循环演变的猜想、万物一体的生态论;老庄尤其确认了人的自然本质及在自然界中的位置,并由此衍生出了老庄的养生论,所有这些都显示了老庄哲学独有的理论品质以及它在理论上的前瞻性、现代性。     

社会系统及其生态性研究

在中国,提出"社会系统"的科学概念并对"社会系统"作科学而深刻的研究是在20世纪80年代以后,时至今日,也未形成有代表性的一般理论。而在国外,对"社会系统"的研究由来已久,并形成了不同的学派,尤其以帕森斯的社会系统一般理论、社会系统生态性理论为突出代表。同样,中国学者对社会系统的生态性的关注,也是近些年的事。本文对"社会系统"和"社会系统生态性"作出了明确的界定。     

从生态-能量系统通往更深层的文化唯物主义--论中国地域文化研究对西方文化学最新成果的批判借鉴

作为一种文化唯物主义理论,西方流行的"文化进化论"中有一些成分值得中国地域文化研究加以批判借鉴。其中,"文化生态学"和"文化进化能量法"以及"新进化论"等学说,均在一定程度上与唯物史观有所契合,对我们解剖中国地域文化的异同提供了某种基本视角。     

教育伦理生态系统探析

教育伦理的内涵根源于人本性的变动性。“人的成长”与教育的“共生同构”关系清晰地映射出教育伦理生态系统。教育价值生态和教育实践生态是教育伦理内涵的充分展开。只有从人的本质为出发点才能真正解释教育的伦理内涵。这对于把握教育伦理生态系统,深刻理解教育实质,加大教育体制改革力度,优化教育资源结构,提高办学效益和水平,都有重要的理论意义和深远的历史意义。

Professional discourse in winning images: objectivity and professional boundaries in environmental news images in the World Press Photo contest, 1992–2011

This article applies the ecological theory of professions to analyze professional discourse in the World Press Photo (WPP) contest, an international photojournalism contest held in Amsterdam, the Netherlands. The article analyzes the content of 148 photojournalism works that received environmental awards in the period 1992 to 2011, the two decades after the 1992 Earth Summit in Rio de Janeiro. The article seeks to understand the representation and negotiation of objectivity and the claims of professional boundaries by the media of both developed and developing countries as well as non-governmental organizations (NGOs). It also seeks to interpret the professional discourse of the WPP in relation to ideologies and power dynamics in both journalism and global environmental politics. The results suggested that the media of developed countries dominated the discourse, and the conventional notion of journalistic objectivity remained intact. However, the results also showed that global environmental politics and the situation of journalism created openings for the media of developing countries and NGOs to enlarge jurisdictional claims in the area of natural disaster reporting and to challenge the conventional notion of objectivity. The results also showed that the conventional notion of objectivity did not necessarily hinder explanations of the complexity of environmental issues, which was made possible by choosing unique angles of storytelling, planning multiple shots, and using richly suggestive, naturalistic images.

马克思辩证法次生态衍义之应然意蕴与可然诠释

近年来，在对马克思辩证法做“原生态”解读与超越的衍义进程中，出现了某种程度上的偏离马克思辩证法本真精神的倾向。笔者对马克思辩证法衍义的“应然”与“可然”意蕴作了尝试性的阐释，旨在还原马克思辩证法的本来面目。     

A comparison of classification models to identify the Fragile X Syndrome

The main models of machine learning are briefly reviewed and considered for building a classifier to identify the Fragile X Syndrome (FXS). We have analyzed 172 patients potentially affected by FXS in Andalusia (Spain) and, by means of a DNA test, each member of the data set is known to belong to one of two classes: affected, not affected. The whole predictor set, formed by 40 variables, and a reduced set with only nine predictors significantly associated with the response are considered. Four alternative base classification models have been investigated: logistic regression, classification trees, multilayer perceptron and support vector machines. For both predictor sets, the best accuracy, considering both the mean and the standard deviation of the test error rate, is achieved by the support vector machines, confirming the increasing importance of this learning algorithm. Three ensemble methods - bagging, random forests and boosting - were also considered, amongst which the bagged versions of support vector machines stand out, especially when they are constructed with the reduced set of predictor variables. The analysis of the sensitivity, the specificity and the area under the ROC curve agrees with the main conclusions extracted from the accuracy results. All of these models can be fitted by free R programs.
