风险社会中突发事件的特征与处置理念探析

突发性事件由于其本身所具有突发性、紧急性、危重性、复杂性、关联性、广泛性、政治性和不确定性等特征，所以其负面性影响很大，往往可能成为激发社会矛盾、进而爆发政治、经济和社会危机的直接原因。而经济转轨、社会转型、利益群体多元化等许多不稳定的因素，对局部地区乃至全国的经济发展和社会稳定构成了潜在威胁。在这样一个具有诸多风险因素的社会，由此而引发的突发事件又有形式多元化、规模扩大化、形态群体化、影响辐射化、目标国际化等特点。所以，在现阶段，处置突发事件的理念必须适应这种风险社会的公共危机特点，做到危机缓和，未病先防；以人为本，取信于民；利益调和，治病求本。

2 种不同性能炭纤维载体的固定床厌氧反应器运行效果比较简

分别采用炭纤维（CF）和活性炭纤维（ACF）作为固定床厌氧反应器的生物膜载体，以不加任何载体的相同规格的反应器为对照，在中温（35±1）℃、连续进料条件下处理高浓度糖蜜废水，实验历时 165 d ，比较评价了2种不同性能的炭纤维作为载体的固定床厌氧反应器的运行性能。结果表明，CF 和 ACF 均是较好的微生物附着的载体材料，具有较强的处理高负荷有机废水和抵抗pH冲击的能力，能显著地提高反应器运行系统的稳定性。具有高比表面积的 ACF 较之 CF 更易于微生物固着并挂膜。对照在进水 COD超过 20 000 mg/L，相应 OLR为 8.35 kg COD/（m³·d）时，系统开始酸化。而以 CF 和 ACF 为载体的反应器能在进水 COD 高达 70 000 mg/L ，相应的 OLR 分别为 36.85 和 39.06 kg COD/（m³·d） 的高有机负荷下运行，且系统的pH更稳定。对照及以 CF 和 ACF 为载体的反应器的最高容积产气率分别为4.33、17.12和16.12 m³/（m³·d）；165 d 的累积产气量分别为5 665.4、22 675.8和26 112.8 L，后2者的产气量分别是对照产气量的 4.0 和 4.6 倍。

The relative contribution of visual and auditory cues to environmental perception

This study assesses the relative dominance of vision and hearing in judgments of environments, and examines whether the sound sensitivity of the judge alters relative sensory dominance. Six sets of four composite (auditory-plus-visual) videotaped environmental displays were created from unisensory visual and auditory components with known levels of evoked affect. These displays, in a 2 (high, low) × 2 (high, low) Pleasure and/or Arousal format, were presented to 70 participants. The results indicate that visual cues dominate auditory cues in judgments of Pleasure, but that the degree of dominance is highly variable. Arousal judgments were not consistently related to visual or auditory cues. Sound sensitivity does not appear to influence the relative dominance of vision.     

Disembodied and Disembedded? The Social and Economic Implications of Atmospheric Change and Biodiversity

The social and economic implications of atmospheric change on biodiversity need to be seen in a global context of major shifts in the conceptualization and management of our relationship with nature. Traditionally, we have conceptualized the atmosphere and the other creatures of the biosphere as separate from the human, but their quasi-autonomy is now becoming subject to more and more human management. This raises not only economic issues, but social, political, and ethical concerns that will have substantial influence on public policy. Among these are the commodification of genetic material; the privatization of traditional knowledge; and the management of information. In this broader context, the paper examines an array of current and proposed strategies of response to changes in biodiversity as a result of climatic and other stresses.     

Monitoring Sustainable Forest Management in Different Jurisdictions

The concept of sustainable forest management (SFM) requires forest resource managers to monitor and collect information pertaining to their environmental, economic and social impact. There are increasing expectations from a variety of publics (government, customers, and other stakeholders) that forests be demonstrably well-managed, creating incentives for forest managers to design credible systems for assessing their management performance. It is against this background that local, national and international approaches to regulating forest practices have been evolving. This article reviews the different dimensions of governance as they relate to monitoring and information reporting in the forest sector. Specifically, it discusses the changing role of sovereignty, the effects of globalization and the emergence of civil society stakeholders in forestry-related decision-making. Concepts such as sovereignty and globalization have important implications for monitoring forest practices and for defining SFM. Whether SFM standard creation and enforcement involves a sovereign, shared-sovereignty or civil society approach will affect the level and nature of SFM monitoring. As a result, we need to better consider the concept of monitoring appropriate to the scale and intensity of operations, how monitoring and information reporting standards differ between jurisdictions, and what this means for independently verifying SFM at an inter-jurisdictional level.
