Observer determination of the make,model, and year of questioned vehicles

Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year.     

Analysis of off-farm work decisions among smallholder farm households in Burkina Faso

This article investigates off-farm work decisions by smallholder farm households. Using data on 1,101 households from Burkina Faso, it demonstrates that in addition to the usual household socio-demographic characteristics, remittances, access to information and beneficiary of specific training affect off-farm work decisions, as well as rainfall factors and idiosyncratic health shocks. Community characteristics such as accessibility and number of inhabitants are also key factors. While suggesting that off-farm work is less likely to be undertaken for accumulation purposes, these results have important policy implications. In particular, policy measures should consider each segment as a separate entity.     

Children in the environment: Forest day-care centers: Modern day care with historical antecedents

Some features of early child care are more prominent in Norway than in other countries, such as emphasis on the outdoor environment. Of general relevance and interest is the form of day care provided by forest day-care centers. Three ideas form the development of these centers placed in wild areas. First, throughout history, Norwegians have had a close attachment to nature and some parents want to provide their children with outdoor experiences at an early age. Second, urging children to play outdoors characterizes the image many parents have of a happy, healthy childhood. Third, provision of day care for children has always been restricted in western countries, forcing parents to invent types of service that can become part of an ecological system that promotes healthy development.The forest day-care centers developed recently represent a supplement to the wide typology of child care in the 21st century. The article outlines the connections between these ideas in general European and western history and Norwegian history and presents debate and decisions about a question dating from the last half of the 1980s. It concludes that the forest day-care centers are perhaps only a modern form of the original kindergarten concept, which started in Europe and America as gardens for children not gardens of children.     

论环境与资源诉讼中的公益理念

环境权从某种意义上属“社会性”权利 ,无论在立法还是司法实践中 ,这一权利都带有明显的公益色彩。为保障公民环境权的实现 ,我国应借鉴西方国家经验 ,放宽对环境诉讼起诉资格的限制 ,对现行司法制度进行制度创新     

试论拯救环境危机的多维视角

人类的活动已经破坏了自己赖以生存的自然条件,使整个地球陷入了资源枯竭和环境污染的危机。人类限制自己危害环境活动的途径,除了要在观念和意识上引起重视而外,还要通过法律和行政制度的强制力来约束人的行为,同时还应该在构建共同的生态环境伦理方面通力合作,共同参与,为人类共同的未来做出自己的努力。     

Scale, technique and composition effects in the Mexican agricultural sector: the influence of NAFTA and the institutional environment

More than a decade after NAFTA (North American Free Trade Agreement) entered into force, the environmental effects of agricultural trade liberalization in Mexico are still controversial, emerging, and not fully understood. This paper contributes to the literature that aims to explore trends in input use in the agricultural sector in Mexico during the post-NAFTA period among both commercial/industrial and traditional/rainfed farmers, and examines the influence of the national and multilateral institutional framework on these outcomes. We decompose the post-NAFTA agricultural production data into scale, technique and composition effects to estimate the impact that trade liberalization has had on the use of fertilizer and land use, two key agricultural inputs for which reliable aggregate data is available. We conclude that among commercial farmers patterns of crop type specialization and significant technological improvements have led to some declines in fertilizer use but they have been offset by growth in fertilizer use associated with growing agricultural output. Among traditional farmers increased output and specialization in land-intensive grain crops are contributing to an increase in land under cultivation and technological improvements show the potential, but not yet not the strength, to counteract these effects. We analyse the environmental institutional framework and rural development plans, observing that institutional weaknesses have, in several instances, reduced the environmental benefit of technique and composition effects. We conclude with recommendations about how the Mexican agricultural sector might reap the environmental benefits of international agricultural trade.

Strengthening Green Global Governance in a Disparate World SocietyWould a World Environment Organisation Benefit the South?

The debate on the advantages and disadvantages of upgrading the United Nations Environment Programme to a 'world environment organisation' (WEO) has gained momentum in both academe and politics. This article contends that a WEO would further the interests especially of developing countries, because it would provide them, first, a high-level forum to unite their individual bargaining power against the major industrialised countries. Second, a WEO would assist Southern efforts to garner international support for environmental programmes in regions and sectors that are increasingly bypassed by economic globalisation. Third, a WEO would create a locus to politically institutionalise the influence of non-governmental lobbyists in a way that increases the balance of opinions and perspectives. The article then addresses special challenges and caveats for developing countries in the upcoming negotiation process, in particular whether an upgraded UNEP would address only 'global' issues, thus absolving the international community from assisting developing countries in mitigating the more pressing local environmental issues in the South; whether the new body would have powerful sanctioning mechanisms, which might disproportionally affect developing countries; and what decision-making procedures the new body would have.

生态文明——人类发展的必然选择

生态文明作为人类文明的一种形式,是人类对传统工业文明进行理性反思的产物,是人类发展的必然选择.党的十六大将生态问题纳入基本国策,将生态文明建设列入全面建设小康社会的重要目标.建设生态文明是明智的选择,也是一项刻不容缓的任务.生态文明建设是一个复杂的综合性的工程,需要摈弃功利主义发展观,树立人与自然和谐发展的新观念,需要人们生态意识的培养与素质的提高,需要决策层的正确引导,需要法律、法规的约束等措施来实现.
