The Value Of Public Participation During a Hazard,Impact, Risk And Vulnerability (HIRV) Analysis

The first part of this paper discusses the links between hazard, risk and vulnerability (HRV) analysis and the development of mitigative strategies. The second part discusses the need to include public participation when completing an HRV analysis. Two current HRV models are used to illustrate the general failure of HRV analysis to include public participation. The third part of this paper provides a brief overview of the Hazard, Impact, Risk and Vulnerability (HIRV) model and its use of public participation. The paper concludes by offering a synopsis of a case study in the town and regional area surrounding Barriere, British Columbia, Canada. This case study demonstrates a positive outcome when public participation is incorporated into an HIRV analysis.     

中国PM_(2.5)污染状况和污染特征的研究

近１０ 余年来在中国的城市地区和清洁地区进行了ＰＭ２－５ 的采集和分析，其中包括ＰＭ２－５ 的质量浓度、离子和元素成分、酸度和酸化缓冲能力以及来源解析，研究结果表明，中国大部分地区ＰＭ２－５ 的污染较重，不论是质量浓度，还是各种主要成分浓度，在ＴＳＰ 和ＰＭ１０ 中都占有很高的比重，而ＰＭ２－５ 的酸度也远远高于ＴＳＰ 和ＰＭ１０ ，特别是近年来ＰＭ２－５ 污染还有相对加剧的趋势。

闲话广场

如今,广场在大大小小的城市次第出现,甚至连小镇也辟出广场来.撇开建广场的决策者们功利目的不谈,广场多几个,应是好事.起码,人们休闲散步也有个去处.但广场是讲究文化氛围和环境气氛的,究竟是以庄重肃穆为上,还是以自在安详为佳,可能各有想头各有执词,也许有人更直接：这得根据广场设计的主题来定.     

Predatory spider mimics acquire colony-specific cuticular hydrocarbons from their ant model prey

The integrity of social insect colonies is maintained by members recognising and responding to the chemical cues present on the cuticle of any intruder. Nevertheless, myrmecophiles use chemical mimicry to gain access to these nests, and their mimetic signals may be acquired through biosynthesis or through contact with the hosts or their nest material. The cuticular hydrocarbon profile of the myrmecophilous salticid spider Cosmophasis bitaeniata closely resembles that of its host ant Oecophylla smaragdina. Here, we show that the chemical resemblance of the spider does not arise through physical contact with the adult ants, but instead the spider acquires the cuticular hydrocarbons by eating the ant larvae. More significantly, we show that the variation in the cuticular hydrocarbon profiles of the spider depends upon the colony of origin of the ant larvae prey, rather than the parentage of the spider.     

Landmark memories are more robust when acquired at the nest site than en route: experiments in desert ants

Foraging desert ants, Cataglyphis fortis, encounter different sequences of visual landmarks while navigating by path integration. This paper explores the question whether the storage of landmark information depends on the context in which the landmarks are learned during an ant's foraging journey. Two experimental set-ups were designed in which the ants experienced an artificial landmark panorama that was placed either around the nest entrance (nest marks) or along the vector route leading straight towards the feeder (route marks). The two training paradigms resulted in pronounced differences in the storage characteristics of the acquired landmark information: memory traces of nest marks were much more robust against extinction and/or suppression than those of route marks. In functional terms, this result is in accord with the observation that desert ants encounter new route marks during every foraging run but always pass the same landmarks when approaching the nest entrance.     

Inter and intra-population variation in shoaling and boldness in the zebrafish (<Emphasis Type="Italic">Danio rerio</Emphasis>)

Population differences in anti-predator behaviour have been demonstrated in several species, although less is known about the genetic basis of these traits. To determine the extent of genetic differences in boldness (defined as exploration of a novel object) and shoaling within and between zebrafish (Danio rerio) populations, and to examine the genetic basis of shoaling behaviour in general, we carried out a study that involved laboratory-raised fish derived from four wild-caught populations. Controlling for differences in rearing environment, significant inter-population differences were found in boldness but not shoaling. A larger shoaling experiment was also performed using one of the populations as the basis of a North Carolina type II breeding design (174 fish in total) to estimate heritability of shoaling tendency. A narrow-sense heritability estimate of 0.40 was obtained, with no apparent dominance effects.     

Framing the Long-Term <Emphasis Type="Italic">In Situ</Emphasis> Liability Issue for Geologic Carbon Storage in the United States

This paper examines how legal standards of liability may apply to geologic carbon storage. The liability regime governing geologic carbon storage will shape the technology's cost-effectiveness and overall attractiveness. We classify potential sources of liability into operational, in situ, and climate liability. As a first step, we explore in situ liability in the United States. After summarizing legal standards of liability including negligence, breach of implied warranty, strict liability, and product liability, we discuss how liability may be addressed at the level of the federal government, state government, industry, and the firm. Finally, we address the implications of judicial treatment of liability for carbon storage, including the apportionment of liability and the adequacy of current regulations.     

低空分层降水和云水同步采集系统的开发和应用

笔者自行开发并研制了低空（ ＜ １ ｋｍ） 分层降水和云水采集系统，该系统成功地应用于福建省厦门市和贵州省贵阳市酸性降水来源和成因的研究中，取得了显著的成果，为探讨酸性降水来源和成因提供了有效的技术手段和支持。该系统可以在一定程度上代替航空测量，目前国内外的类似研究中没有使用该系统进行样品采集的先例，因此该系统的开发填补了国内外相关研究领域的空白
