Assessment of Riparian Rainforest Vegetation Change in Tropical North Queensland for Management and Restoration Purposes

Changes in riparian vegetation extent in northern Queensland, Australia were assessed using aerial photographs from 1944 and 2000. Change in riparian extent was recorded as vegetation gain or loss. Changes in density were recorded as vegetation thickening. Riparian forest coverage increased by 22 ha during this time period in the Mossman River catchment. A total of 124 ha of riparian forest were gained, while 101 ha of riparian forest were lost. A further 59 ha of forest increased in density over this time period. Clearing, changes in farm management practices and natural stream channel movement have been identified as three potential causes for these changes. Areas with little or no riparian vegetation were identified and categorised into priority levels for potential revegetation efforts.     

Messen und Zählen. Die Herstellung des normalen Menschen als Maß der Gesundheit

The emergence of a ‘norm of normalcy’ in 19th century laboratories and hospitals was in no way simply a byproduct of the scientific search for knowledge. It was instead closely associated with expectations of social egalitarianism which merged with the moral economy of a new scientific objectivity. The establishment of normal people as a valid measure for a population socially divided and segregated in estates was thus an essential element of the processes of social formation which created our modern society.

喀斯特山区城市地域结构问题及其优化对策——以贵阳市为例

贵州喀斯特发育典型,碳酸盐岩出露面积占全省土地总面积的73%,全省主要城市都坐落在喀斯特地区,城市地域结构问题突出,并业已成为城市可持续发展的障碍。本文以贵阳市为例,在阐述贵阳城市地域结构现状问题的基础上,剖析了贵阳城市地域结构问题产生的原因,并据此提出了贵阳城市地域结构优化的对策措施。     

中国国家博物馆环境空气质量监测报告

为加强博物馆藏品的预防性保护,需全面掌握博物馆馆舍内外空气质量的现状,对其进行评估,进而采取有效措施治理改善,妥善保护人类文化遗产。本馆采用美国普滤(Purafil)公司研发并提供的检测技术,在馆舍内外选定八个测试点进行了腐蚀试片测试。根据监测数据得知,本馆处于高浓度极具腐蚀性的二氧化硫气态物质的包围中,已造成对金属、纸张等文物的危害,治理改善收藏环境迫在眉睫。创造保存各类藏品的微环境空间,是治理改善博物馆收藏环境的有效手段。     

The cologne map publisher Peter Overadt (fl. 1590–1652)

Abstract

Peter Overadt is one of the many lesser‐known figures of the second generation of the Cologne school of map making, which had been founded about 1570 by Frans Hogenberg. Overadt is noteworthy as the first continental publisher (aside from Jodocus I Hondius, who was at that time active in London) to have decorated printed topographical maps with marginal historical‐political images. During the first phase of his business (1592–1600), he issued eight maps, with a three‐sheet map of Germania as the pinnacle of his production. After 1600, Overadt's firm was primarily engaged in the publication of religious prints with a Catholic orientation. Topographical productions from this later period are three large town views and the re‐issue of a map of the Rhine area, printed from a re‐worked copper plate of 1594 by Theodoor de Bry.     

环境公正视角下空气污染和死亡人数的空间分析及关系研究——以河北省为例

基于空气污染的环境公正研究在国际上受到较多关注,但在发展中国家、尤其是中国,相关研究较为缺乏。本文使用2010年河北省人口普查和空气质量数据,采用空间分析、描述性统计以及空间回归模型等方法对基于乡镇街道层面的空气污染和死亡人数的空间分布、社会分布及其关系进行研究。结果表明,河北省空气污染和死亡人数在城市和农村地区存在显著差异;基于乡镇街道层面,河北省的婴儿（1岁及以下）、老年人（60岁及以上）、失业者和省外农村流动人口更多地居住在空气污染比较严重的地区;婴儿、老年人、使用固体燃料或住房无洗澡设施的家庭户聚集的乡镇街道其死亡人数较多;空气污染与死亡人数之间存在显著的正相关。本研究旨在促进对中国环境公正与健康不平等的理解和认识,为发展更为公平、有效的环境健康政策提供科学依据。     

Morphometry of Middle Bronze Age palstaves by Discrete Cosine Transform

The Discrete Cosine Transform (DCT) is a Fourier-related transform widely used in signal processing and well suited to the analysis of open outlines. This method was applied here to evaluate the discrimination power of the inner lateral rib for two palstave populations dating from the Middle Bronze Age, excavated in northwest France. A corpus of almost 400 palstaves (bronze axes) of the Breton and Norman types was processed, and compared to specimens found at Sermizelles in Burgundy. The procedure is robust and produces a discrimination in good agreement with the traditional typology. Besides the definition of a ‘standard’ shape for each population, the morphometrical approach allows shape disparity, which is generally inaccessible to the naked eye, to be visualised and quantified. Shape disparity indicates that, contrary to previous assumptions, the bronze axes from the Sermizelles hoards cannot be explained as an assortment of Breton and Norman palstaves alone. We believe that this approach is quick, reproducible, and generalisable enough to be applied to a wide variety of artefacts from different periods, in order to clarify their typology and even their origin.     

Geographies of mediation: Market development and the rural broker in Maharashtra, India

This paper explicates the role of community-level intermediaries in post-liberalized economic sectors. Focusing on nascent commercial markets for improved, smokeless cookstoves in southwestern Maharashtra, I describe how development is encountered by three analytic groups – artisans, female stove users and NGO field officers. This study highlights patterns of strategic intermediary action, or forms of brokering, used to negotiate the commercialization process for individuals involved in the fabrication, distribution and use of improved cookstoves. A close analysis of the mediating agent can strengthen theories on how individuals and communities encounter sector privatization and state retrenchment. This study reveals a diverse set of brokering activities and actors, and shows how intermediaries combine tasks associated with traditional conceptions of the political fixer and market broker by working within and between groups of market, village and state operatives to transform market supply chains. Mediating agents coordinate counter regulating activities within civil society in the absence of heavy state intervention and play a crucial role in activating and connecting community interests to latent neoliberal state resources.     

Let no space go to waste: comparing the uses of space between two Late Classic centers in the El Paraíso valley,Copan, Honduras

Phosphorus analysis of earthen and plaster floors has been used in Mesoamerica to locate and identify activities at ancient sites. This study uses phosphorus analysis to discern if the inhabitants of two Late Classic coeval and proximal sites located in the El Paraíso Valley of Honduras were different culturally from each other. The buried earthen and plaster surfaces of both sites were systematically sampled and analyzed for phosphorus remains. The patterns of elevated phosphorus from these open spaces were subsequently compared to determine if differences in the habitual use and treatment of open spaces could be discerned. These differences are evaluated as a function of behavioral norms, functional responses, and cultural dispositions in order to evaluate the extent to which these two populations were indeed different from each other.
