Antagonistic structures in border areas: Local milieux and local politics in the Polish-German twin city Gubin/Guben

Cross-border communication and co-operation at the Eastern fringe of the European Union seems so far to have been a matter of political initiative and a lot of good will at the levels of national, regional and local governance. This article maintains that everyday culture must be given more notice when cross-border activities are regarded at the local level, especially in twin cities. The case of the German-Polish twin city Guben/Gubin reveals a strong tendency towards a new divergence of thought and action between formal and informal levels of action, namely the level of local politics and governance and the level of local everyday milieux. While the politics of Euroregions, local administrations and local governments is very often directed towards establishing symbolic gestures of border-crossing and mutual understanding, social milieux at the ‘base’ of local societies are rather driven by a paradoxical mixture of hope, anxiety, resentments and prejudice, thus producing contradictions and even conflict with official political initiative.

Ecological conflicts in Poland

Transformation of the political system, observed in Poland for 10 years in connection with economic restructuring and basic socio-economic reforms to harmonise with European Union structures, is also evident in terms of environmental management. Pollution has been reduced in many ways but the rise in living standards, linked with the rapid growth of cars and other forms of consumption, has had a negative effect and environmental conditions have deteriorated in the central areas of large cities. The growth of waste water and refuse is a considerable problem. More areas are now officially protected and the three levels of local government established at the beginning of January 1999 (voivodeship, district and community) all have certain defined environmental protection responsibilities which are cumulatively greater than before. Meanwhile there is a greater awareness in society of environmental issues, although it does not yet lead to a high level of participation in protection work. However, there are strongly-expressed opinions on the ecological acceptability of certain economic developments and conflicts are frequently arising within communities and local governments and also between investors on the one side and ecological organisations and environmental protection institutions on the other. Most controversial are new roads, power stations (like the Zarnowiec nuclear project) and reservoirs like the one on the Dunajec river at Czorsztyn. Local communities frequently resist plans for waste dumps, incinerating plants and other developments which are seen as injurious to health or the quality of life. The planned reprivatisation of the state-owned forests is also criticised by foresters and ecological movements. Conflicts are likely to grow as economic development accelerates but better information and greater public understanding of the need for sustainability should make for consensus.

吉林省突发性暴雨的时空分布特征

使用吉林省５４个气象站１９６０－１９９２年逐日、逐时降水资料，分析定义突发性暴雨过程，并从时空分布及地形影响等方面对各种突发性暴雨进行了分析，得出它们之间在时间分布和地理分布上的差异，为此类天气分析预报提供气候背景。     

我国草原下垫面低层大气湍流结构

利用超声风速仪资料分析了科尔沁草原下垫面低层大气的湍流谱结构，无量纲化湍流速度分量及温度脉动的标准偏差，和湍流通量与稳定度参数的关系。结果表明，草原下垫面低层大气湍流速度谱，在较宽的稳定度范围内， 符合Kolmogorov 相似理论，在惯性副区接近局地各向同性，无量纲化湍流速度分量及温度脉动的标准偏差服从A(1-Bζ)1/3和A(-ζ)-1/3规律， 湍流热通量与稳定度参数ζ存在较好的相关性。

论地方地震科研工作的制约因素及改革对策

本文列据说明地方地震科技队伍是一支重要力量，但与专业地震科学队伍相比较，因制约因素多，存在很大差距，要发挥地方地震科学队伍的作用，必须走改革之路，在认识上、组织上、步调上应该协调统一，以达到专群，上下真正结合。     

震前大气电场异常的区域性特征

在了近场每次较大地震发生前，均能观测到明显的大气电场负异常信息。在观测不到明显的大气电场负异常时，近场近期一般不会有较大地震发生的基础上，本文对北京及其附近地区为例，利用所观测到的在气电场异常资料及１９８５年后该地区所发生的８次Ｍｌ≥４地震资料，较深入地探讨了震前大气电场异常的空间分布特征，取得了一些规律性的认识：（１）异常多发生在距震中不太范围内，且随着震级的增大异常区的范围也增大。（２）较大地     

冀东牛心山金矿区岩浆岩特征及其成因探讨

本区岩浆岩以花岗岩为主体,只在岩浆演化晚期有少量中性岩岩墙。岩浆演化及岩石化学、稀土元素、同位素等特征表明,岩浆是燕山运动早期构成下地壳的基性物质经部分重熔形成,熔融早期最低熔融组分形成花岗岩浆,进一步重熔,晚期形成少量中性岩浆。
