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.

社会主义荣辱观探讨

社会主义荣辱观的思想渊源在于中外传统道德中的荣辱思想特别是马克思主义荣辱学说。社会主义荣辱观的现实基础在于当前经济、政治、文化发展的迫切需要。社会主义荣辱观的鲜明特色在于弘扬了中华民族的传统美德,弘扬了人类文明的积极成果,彰显了社会主义的时代精神,反映了人民群众的普遍诉求,建构了振兴中华的精神脊梁。

男性犯罪青少年人际信任与社会支持、应对方式的关系研究

通过对山东省少年管教所189名男性犯罪青少年人际信任的特点以及与其社会支持、应对方式的关系进行研究发现:(1)男性犯罪青少年人际信任水平比同龄男性中学生低,且差异显著;(2)其社会支持与人际信任水平呈正相关;(3)积极应对方式与人际信任水平呈正相关,消极应对方式与人际信任水平呈负相关;(4)人际信任、社会支持和应对方式之间存在复杂的因果关系;(5)各种客观变量对人际信任的影响甚微.     

论全球化背景下的中国非物质文化遗产保护

我国非物质文化遗产保护问题,有其历史的和社会的、国际的和国内的背景,是回应历史发展的要求而提出的。非物质文化遗产既是建设现代民族文化的基础,也是每个民族对世界文化的丰富和贡献。因此必然要从全人类的视角来看待非物质文化遗产保护问题。从古今文化关系的角度说,非物质文化遗产在多数情况下,既是昨天的实录、今天的现实,同时也是明天的预示;从东西方文化关系的角度看,吸纳外来文化和继承原有传统并不是矛盾的,二者所形成的张力对于创造新的文化起着非常重要的作用。然而,由于非物质遗产大都是农业社会条件下的产物,所以今天对它的保护便包含着许多悖论。例如,保护和发展的关系,结构性对象的解构性保护,对传承人的态度,市场经济体制和非物质文化遗产保护等,都隐含着诸多两难的问题,期待着文化行政部门、学术界以及整个社会给出两全的解决方案。因此,对于非物质文化遗产的保护应该贯彻整体性的原则,从整体上加以认识,进行整体性的保护。从根本意义上说,非物质文化遗产的保护,首先应该是对创造、享有和传承该文化遗产的人的保护;同时,对这一遗产的切实有效的保护,也特别依赖于创造、享有和传承这一遗产的群体。促进和保护文化的多样性发展,才是我们努力追求的目标。     

As low birth weight babies grow,can well-educated parents buffer this adverse factor? A research note

This research note combines two national Taiwanese data sets to investigate the relationships among low birth weight (LBW) babies, their parents' educational levels, and their future academic outcomes. We find that LBW is negatively correlated with the probability of such children attending college at age 18; however, when both parents are college or high school graduates, such negative effects may be partially offset. We also show that discrimination against daughters occurs, but only for daughters who were LBW babies. Moreover high parental education can buffer the LBW shock only among moderately LBW children (as compared with very LBW children) and full-term LBW children (as compared with preterm LBW children).

文官政治·书卷风流·人文气象--宋代文学存在的社会文化背景分析

有宋一代 ,文化大昌 ,文学也出现繁荣气象 ,这同宋代的社会环境及文化背景密切相关。宋型文化 ,有着向内收敛及注重人文涵养的倾向 ,这也深深影响了宋代文学及文学思想。简言之 ,宋代社会的基础是文官政治 ,内在精神是注重品性涵养 ,外在的表现是书卷风流。它们三位一体 ,构成了宋人所处的富于浓郁人文气息的氛围 ,其审美情趣也从外在的羁旅漫游、征戍迁谪、行旅离别 ,逐渐转向丰富多彩的心智活动 ,于是构成宋代文学及文学思想中博大精深的人文气象     

岩石夫人与风信子女郎--论<荒原>女性形象与西方文化传统之关系

西方文化传统对女性与文明之间关系的定位是将女性之精神性宏扬为拯救文明的“天使”,同时将她的肉体性贬低为导致文明堕落的“魔鬼”。英国诗人艾略特借用这一传统中的典型意象符码 ,在长诗《荒原》中构建“岩石夫人”与“风信子女郎”两组女性人物 ,表达“天使”理想在现代社会的失落和由此造成的精神贫瘠、“荒原”般的生存状态。艾略特对传统的借鉴是由诗人的创作观、个人生活和社会现实三方面决定的
