Coping strategies in rural areas of the Buzau Sub–Carpathians

This paper focuses on the Sub–Carpathian region which has traditionally maintained a large rural population and is today suffering acute economic and social stress. During the present transition phase the rural population is struggling to survive by combining elements of the modern and traditional economies and research has been undertaken to clarify a range of household strategies. After profiling the communes of the Buzau Carpathians the problem is tackled at two levels on the basis of questionnaire work carried out during 1998–1999. First there is a general overview to outline conditions in Patarlagele commune, including some local contrasts between settlements on main transport axis along the Buzau valley and those in the hills and side valleys. Second there is a consideration of in-depth profiles of specific households in villages in the wider area including Panatau as well as Patarlagele commune. It remains to be seen to what extent the district will be able to safeguard its social capital when growth resumes in large towns especially Brasov and Buzau with which Patarlagele has the best contacts. It is also an open question how far the remoter settlements will retain a viable population, assuming that the services remain relatively poor while disadvantage persists with regard to both employment opportunities and physical security. This revised version was published online in July 2006 with corrections to the Cover Date.     

Chemical and structural defensive external strategies in six sabellid worms (Annelida)

In the marine environment, sessile invertebrates have developed an impressive array of mechanisms to avoid predation, bacterial exploitation, and epibiotic overgrowth. In the present study we investigated several defensive strategies adopted by six sabellids: the hard bottom species Sabella spallanzanii (Gmelin, 1791), Branchiomma luctuosum Grube, 1869, Branchiomma bairdi (McIntosh, 1885), and Sabellastarte spectabilis (Grube, 1878), and the soft bottom species Myxicola infundibulum (Renier, 1804), and Megalomma lanigera (Grube, 1846), which have different morphological characteristics and geographical distribution. We examined and compared some defensive features such as branchial crown toughness, tube structure and strength, amount of released mucus, and antibacterial lysozyme‐activity in the mucus. The investigated species utilize a combination of defence and deterrence strategies that seems to be related to the colonized habitat. Tube strength was, higher in the hard bottom species compared with the soft bottom ones, where the tubes are generally buried and protected within the sediment. Branchial crown appeared stronger and resistant in hard bottom species, except for S. spallanzanii, which is the species showing the strongest tube. Sabella spallanzanii, M. infundibulum and S. spectabilis secreted high amount of mucus with high lysozyme‐like activity. By contrast, B. luctuosum, B. bairdi, and M. lanigera produced low amounts of mucus exerting lower antibacterial activity.     

Debris flow disaster prevention and mitigation of non-structural strategies in Taiwan

Taiwan has disadvantageous conditions for sediment-related disasters such as debris flows. The construction of engineering structures is an effective strategy for reducing debris flow disasters. However, it is impossible to construct engineering structures in all debris flow areas in a short period. Therefore, the government aims to gradually develop non-structural preventive strategies, including evacuation planning, debris flow disaster emergency action system, disaster resistant community program, recruitment of debris flow professional volunteers, debris flow warning systems, and land management strategies, to mitigate disasters and secure the safety of residents. This review describes the processes and effects of recent debris flow non-structural preventive strategies in Taiwan. The average number of casualties prior to the year 2000 was far higher than the corresponding number after 2000 because debris flow evacuation drills have been promoted since 2000 and the debris flow disaster emergency action system has been progressively improved since 2002. Furthermore, the changes in risks caused by debris flow disasters before and after the implementation of non-structural preventive strategies were used to explain the effectiveness of these strategies at the community level. The results showed that software-based non-structural preventive strategies can effectively reduce the casualties caused by debris flows at both the national and community levels.     

Policy Change and Venue Choices: Field Burning in Idaho and Washington

Grass seed farmers have burned their fields in Idaho and Washington State for decades. Field burning, however, creates small particulate matter air pollution, thus engendering a growing public backlash by the 1990s that manifested itself in new clean air advocacy groups. The new groups’ push for policy change eventually met with significant success in both cases. How did each set of advocates approach the challenge of policy change? More specifically, what kinds of policy venues did each group choose and why? This research uses the cases to explore and explain each clean air group's choices vis-à-vis hypotheses of venue choice. Three hypotheses are tested—Schattschneider's (1960 Schattschneider , E. E. 1960 . The semisovereign people . New York , NY : Holt, Rinehart, and Winston . [Google Scholar]) “expanded scope of conflict” thesis, ACF's (Sabatier and Jenkins-Smith 1999 Sabatier , P. , and H. Jenkins-Smith . 1999 . The advocacy coalition framework: An assessment . In Theories of the policy process , ed. P. A. Sabatier , 117 – 166 . Boulder , CO : Westview Press . [Google Scholar]) contention that groups strategically apply their resources in order to increase the likelihood of achieving their primary goal(s), and Pralle's (2003 Pralle , S.

The importance of estuary head waters as nursery areas for young estuary- and marine-spawned fishes in temperate South Africa

The restriction of freshwater flow into estuaries, the presence of in-stream barriers and the occurrence of invasive fish species in these habitats are identified as major threats to these young estuary- and marine-spawned fish species. These aspects have been investigated using the distribution and abundance of young estuary- and marine-spawned fish species in the headwater environments of four permanently open estuaries of the Eastern Cape, South Africa. Fishes were collected twice per season over the 2009 and 2010 period, using mixed method sampling with seine net hauls and overnight fyke net deployments. Of the 74,751 fishes collected, 37,444 fishes, 18 families and 34 species were taken in fyke net catches, while 34,308 fishes, 21 families and 38 species were caught in seine nets. In the Great Fish, Kowie, Kariega and Sundays River systems, juveniles of estuarine residents dominated headwater catches, followed by juveniles of estuary-dependent marine species. The prevalence of larval and small juvenile stages of estuary- and marine-spawned fish species highlights the potential importance of these transitional areas for young fish.

主要经济体1990—2007年温室气体排放变化及其启示

主要发达国家提交UNFCCC的1990-2006年排放清单数据显示,部分发达国家已采取了确实的减排措施完成《京都议定书》规定的温室气体减排目标,其中,德、英、法、荷和瑞典是履行《京都议定书》温室气体目标效果最好的国家,分析各国所采取的减排政策／措施发现,这些国家完成《京都议定书》目标的实际路径大多是“避重就轻”的,其做法对于我国处于工业化中期的地区,采取非关键领域减排的策略可以为我国经济高速重化工发展腾出一定的排放空间,减少温室气体减排对经济发展的制约。
