城市化进程中少数民族流动人口就业现状、存在问题及其对策分析

城市化进程的加快,必然导致人口流动,更多少数民族人口流动到城市就业.作者对成都市少数民族流动人口就业现状、特征进行了调查,分析了少数民族流动人口就业存在的问题,并就与之相关的对策进行了探讨.     

裸体与审美

文章从事实分析当众裸体的非美学的、为功利的本质。强调裸体不是人类先进文化的符号代表：裸者喊的是“人性解放”,做的是利用人性弱点“偷窥”赚钱。审美经验不对人的心灵做出一些有价值的贡献,就是美育教育的失败。     

“河流伦理”思想及论证中的若干挑战

"河流伦理"概念的提出是现实社会治河理念发展到一定阶段的产物.就应用伦理学而言,在现代民主的"对话-协商-论证"(Dialogue-Negotiation-Argument,简称DNA)序列中,学者的工作主要在于"论证"(A)一环,论证不可能如科学哲学中D-N模型所描述的那种演绎推导一般表现为"必然得出".在努力论证河流伦理的同时,也要考虑传统伦理的论证责任以及范式转变的重要性.     

生命周期评价与环境伦理

评价材料与环境协调性的生命周期评价方法有环境伦理的哲学基础,是环境伦理的核心观点的科学体现。然而,从科学角度来看的生命周期评价方法的局限性则未必真是它的局限性,在对其作出环境伦理学的说明之后,有些局限性不过是哲学与科学的内在矛盾的体现,是科学自身的局限性的折射而已。     

浅论反思性教学与反思途径

"教师发展"是目前教育界关注的焦点,而反思是"发展"的关键环节之一。教师只有学会并掌握科学有效的反思途径,不断对自己的教学行为、教学方法及效果进行反思,才能提高自己的职业判断力,促进自身发展。可以这样认为,反思性教学是教师发展的前提,同时,教师发展又是反思性教学的必然结果。     

Opportunities for woman-initiated HIV prevention methods among female sex workers in southern China

Rapid changes in China over the past two decades have led to significant problems associated with population migration and changing social attitudes, including a growing sex industry and concurrent increases in STIs and HIV. This article reports results of an exploratory study of microbicide acceptability and readiness and current HIV prevention efforts among female sex workers in two rural and one urban town in Hainan and Guangxi Provinces in southern China. The study focused on these women's knowledge and cultural understandings of options for protecting themselves from exposure to STIs and HIV, and the potential viability and acceptability of woman-initiated prevention methods. We report on ethnographic elicitation interviews conducted with women working within informal sex-work establishments (hotels, massage and beauty parlors, roadside restaurants, boarding houses). We discuss implications of these findings for further promotion of woman-initiated prevention methods such as microbicides and female condoms among female sex workers in China.     

城市用语新释(一)

按:目前出版的有关城市的辞书,对于与城市相关的词汇,大都是从城市学、城市经济学或社会学的角度来定义的.许多定义或多或少地把欧美城市的概念套用到中国城市,从中很难了解中国城市用语的特定涵义.更有不少中国城市特有的用语,至今还很少有确切的诠释.《城市用语新释》对近年来出现和使用频繁的城市用语,包括书面用语和口头用语,分条目加以全新的释义.     

Assessing the effects of land use and land cover patterns on thermal conditions using landscape metrics in city of Indianapolis,United States

Direct applications of remote sensing thermal infrared (TIR) data in landscape ecological research are rare due to limitations in the sensors, calibration, and difficulty in interpretation. Currently there is a general lack of methodology for examining the relationship between land surface temperatures (LST) derived from TIR data and landscape patterns extracted from optical sensors. A separation of landscapes into values directly related to their scale and signature is a key step. In this study, a Landsat ETM+ image of Indianapolis, Unites States, acquired on June 22, 2000, was spectrally unmixed (using spectral mixture analysis, SMA) into fraction endmembers of green vegetation, soil, high albedo, and low albedo. Impervious surface was then computed from the high and low albedo images. A hybrid classification procedure was developed to classify the fraction images into seven land use and land cover (LULC) classes. Using the fractional images, the landscape composition and pattern were examined. Next, pixel-based LST measurements were correlated with the landscape fractional components to investigate LULC based relationships between LST and impervious surface and green vegetation fractions. An examination of the relationship between the LULC and LST maps with landscape metrics was finally conducted to deepen understanding of their interactions. Results indicate that SMA-derived fraction images were effective for quantifying the urban morphology and for providing reliable measurements of biophysical variables. LST was found to be positively correlated with impervious surface fraction but negatively correlated with green vegetation fraction. Each temperature zone was associated with a dominant LULC category. Further research should be directed to the theoretical and applied implications of describing such relationships between LULC patterns and urban thermal conditions.
