Environmental Values and Water Policy

The emergence of water markets has heralded the prospect of increased efficiency in the use of the resource for extractive purposes. However, water markets have not encompassed all elements of demand for the resource. Notably, demands for the environmental public goods provided by river flows have not been revealed in markets. State Governments have instituted regulations requiring ‘environmental flows’ to be quarantined from the market allocation process. This policy has triggered negative responses from irrigators and conservationists. Lobby groups have found that the process of determining environmental flows is a prospective site for rent seeking. To avoid policy being driven by rent seeking, information on the costs and benefits of environmental flows is useful. Whereas the costs of environmental flows are readily assessed through reference to market data on irrigators’ surpluses foregone, the benefits must be estimated through the use of non‐market, stated preference valuation techniques. These techniques — including contingent valuation and choice modelling — remain controversial. Some argue that they should not be used on ethical grounds. Others argue that they cannot be used on technical grounds. These arguments are discussed in this paper, using the context of the water policy debate. The evidence is that stated preference techniques are being used, and applications have been performed in Australia in the context of riverine health. However their use remains restricted relative to the scale of the Australian natural resource management task. Some possible explanations for this limited up‐take are provided along with some suggested ways forward.

21世纪中国考古学的若干特点及发展趋势:从“中华文明探源工程”说起——王巍所长专访

21世纪以来,中国考古学呈现出新的学科特点和发展趋势。中国社会科学院考古研究所王巍所长认为,中国考古学随着自身的发展特别是在以"中华文明探源工程"及其各项阶段性成果的推进与影响下,形成了中国气派和中国特色,正朝着科学化、国际化、社会化、大众化的趋势和方向发展;中国考古学需要与国际考古界加强交流,博采众长,走向世界;作为一级学科的考古学的学科建设应是从文物管理机构到文物考古研究机构所共同担负的责任,需要形成一整套既符合中国实际,又顺应中国考古学发展的二级学科的设置,同时培养能够满足考古学发展需要的人才;公众考古是目前考古学新的发展走向,考古界需要转换意识和机制,培养专业人才,坚持考古的纯洁性和道德规范,以更好地服务社会与遗产保护事业。     

Geographic variation in bone carbonate and water δO values in Mendoza,Argentina and their relationship to prehistoric economy and settlement

Questions of mobility, settlement pattern, and their relation to economic organization and resource use are central to ongoing work in central-western Argentina. Here we analyze geographic patterns in the distribution of 178 human bone carbonate δ¹⁸O samples, 46 human tooth enamel carbonate δ¹⁸O samples, and 48 water δ¹⁸O samples from throughout the Andean Cordillera and Monte Desert and evaluate their implications for prehistoric mobility and economy. We confirm and refine previous generalizations regarding a highland/lowland dichotomy in water δ¹⁸O values and show that the range of human carbonate δ¹⁸O values generally reflect available water sources. While there is little within-lifetime change in patterns of water use, we show that most individuals have stable isotope signatures consistent with water use from multiple areas or areas other than where they were ultimately interred. These data indicate high levels of residential mobility, and we conclude by discussing their implications for our understanding of regional prehistory.     

Developing Employment Interview and Interviewing Skills in Small-group Project Work

The value of communications skills in geographical education is briefly discussed. In particular the lack of interview and interviewing practice is noted. The use of realistic interviews as part of small-group project work has been developed at Salford over 10 years. The elements include the drafting of job and person specifications, the writing of a cv and covering letter, and the organisation and running of interview panels. Detail is given of how the whole process is assessed. Negotiation skills are also developed. An important element is the realism of the process. The principal down-side is the amount of staff time involved, but this is more than compensated for by the students' perceived value of the skills developed.     

'Enlivening' Development Concepts through Workshops: A case study of appropriate technology and soil conservation

In comparison with the teaching of most other geography topics, where fieldwork can be conducted relatively easily and seminars can be based on some pre-existing knowledge and first-hand experience of the issues, the range of resources and approaches available to tutors teaching the geography of development is necessarily more limited. Tutors often have to rely more heavily on 'top-down' teaching and more passive learning approaches, such as using videos, slides and lectures. While students may gain a theoretical understanding of development concepts, issues and problems, they may be left without a deeper 'experience' of such material. This paper describes a practical workshop designed to communicate to students the idea of 'appropriate technology'. The workshop enables students to actively 'experience' a development concept rather than simply understand it in theory. It tests comprehension and understanding, through the application of a concept to real examples, stimulates discussion and debate, and draws upon problem-solving and critical thinking skills.     

武王克商年代考

国家"夏商周断代工程"初步确定商周断代在公元前1046年,他们依据的前提是"当年岁星是在鹑火星次",比实际情况--"当年岁星是在天鼋星次",多了6个星次.所以,他们的推算方法虽然是正确的,但是因为所依据的前提错误,结果不对.依据对月象词、星象词和西周时期历法的认识,以岁星(木星)的运行规律可知,牧野之战发生于公元前1039年夏历的三月四日.我们判断,武王伐商是当年的二月一日壬辰,二日癸巳早晨从周地出发,二月戊午师逾孟津,二月晦日越五日甲子在牧野与商纣王战斗.     

Boiled versus unboiled: a study on Neolithic and contemporary human bones

Bones treated at low temperature do not present major modifications although, macroscopically, boiled bones may be distinguished from unboiled ones as they are smoother, lighter and more transparent. Such observations should correspond to textural modifications at a nanometric level and should depend on boiling time. In this study, contemporary human bones, boiled during various time intervals, were characterized using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and nitrogen adsorption (BET). The results were used to estimate the boiling time in four archaeological samples (Neolithic bones from Malalmuerzo cave, Spain). It is concluded, comparing Neolithic bones to contemporary ones and from the textural characterization at a nanometrical level, that two of the archaeological bones were boiled and that they were boiled for less than 6 hours.     

Seismic Hazards and Water Supply Performance

This article describes seismic hazards, including fault rupture, liquefaction, landslides, and site amplification, using Los Angeles as a case study. Water supply simulation results are presented for a 7.8 M_W earthquake on the San Andreas Fault. Severe water losses are shown after 24 h, with nearly 2,700 locations of pipeline damage and a 66% decrease in normal water service. The water supply system was modeled with and without reservoirs that have been removed from service to meet water quality standards. The results show that opening the disconnected reservoirs immediately after a serious earthquake is an effective strategy for emergency response.
