Fire and restoration of the largest urban forest of the world in Rio de Janeiro City,Brazil

National Park of Tijuca in Rio de Janeiro (Brazil) is about 3,300 ha and considered the largest urban forest in the world. Its floristic composition is typical of Atlantic Rain Forest. The reserve is being altered because of fire occurrences and urban expansion. This study identified locations and causes of forest fires, and makes management recommendations to restore damaged areas. From 1991 to 2000, forest firefighters recorded an average of 75-fire occurrences/year. Identified causes included hot air balloons (24%), intentional (24%), rubbish burning (21%) and religious practices (17%). Primary fuels included invasive grasses and ferns. Although hot air balloons destroyed larger areas of forest in each occurrence, a greater number of fires started in the invasive vegetation along roads that bisect the forest. In response to recurrent forests, invasive vegetation has spread gradually into the forest increasing forest degradation. To decrease fire damage, sites with high fire frequencies and density of invasive vegetation were planted with less flammable species. Results indicate that fire frequency decreased and density of invasive vegetation declined. This approach appears to prevent fire incidence, reduce the need for fire fighting, and preserve existing biodiversity.     

法的分类与现代化

世界上所有国家的法按照其与政治、宗教和道德的关系的密切程度来划分,可以分为专业性法、政治性法、宗教性法和道德性法四大类型,其中宗教性法和道德性法属于传统法的范畴,专业性法和政治性法属于现代法的范畴。世界各国法不可避免地发生汇合,现代法正在影响传统法。对于第三世界和其他非西方国家来说,法的现代化是这些国家法律制度改革的方向.     

The potential of integrated modelling in conservation biology: A case study of the black‐footed albatross (Phoebastria nigripes)

Conservation biology aims at assessing the status of a population, based on information which is often incomplete. Integrated population modelling based on state‐space models appears to be a powerful and relevant way of combining into a single likelihood several types of information such as capture‐recapture data and population surveys. In this paper, the authors describe the principles of integrated population modelling and they evaluate its performance for conservation biology based on a case study, that of the black‐footed albatross, a northern Pacific albatross species suspected to be impacted by longline fishing

论过失危险犯

我国学界长期以来都对过失危险犯持否定态度 ,但世界上越来越多的国家开始在刑法中增加规定由危险状态构成的过失犯罪。本文从过失危险犯的现状、立法根据、范围三方面作一探讨     

国际货物买卖合同法律适用问题分析

国际货物买卖合同双方当事人可以协议选择有关国际公约、国际惯例以及某一国或某几国的国内法为合同的准据法。若当事人选择的准据法不是一个完整的合同法律体系,应允许当事人再次选择,这样才能更好地体现意思自治原则。在一般情况下,若当事人选择了《联合国国际货物买卖合同公约》为合同的准据法,合同的准据法就有可能不是单一的,同时还可能会有国际惯例或国内法为合同的准据法。国际货物买卖合同法律适用问题的复杂性应引起我们的注意。

我国区域刑事法律冲突初探

我国各民族之间的差异、民族区域自治制度及其自治权的存在是我国区域刑事法律冲突产生的基本原因,而通过制定顾全大局、兼顾特别的变通性、补充性刑法规范,可缓解这一冲突;通过加快少数民族地区的发展步伐,逐步消除民族之间的政治、经济、文化上的差距,进而达到彻底消除这一冲突,实现法制统一的良好局面。     

Contre-exemple au théorème de P.C. Consul sur la factorisation des distributions de Poisson généralisées

This note exhibits two independent random variables on integers, X₁ and X₂, such that neither X₁ nor X₂ has a generalized Poisson distribution, but X₁ + X₂ has. This contradicts statements made by Professor Consul in his recent book.
