Assuring Development Gains from the International Trading System and Trade Negotiations

The present note draws on the results of intergovernmental discussions in the Trade and Development Board and its subsidiary bodies since UNCTAD X, as well as on analyses by the UNCTAD Secretariat. Its main objective is to facilitate the thematic session's discussion of Assuring development gains from the international trading system and trade negotiations within the conference theme of Enhancing coherence between national development strategies and global economic processes towards economic growth and development, particularly of developing countries. These discussions could explore policy approaches and UNCTAD's contribution to achieving the Millennium Development Goals, including the commitment “to an open, equitable, rule-based, predictable, and non-discriminatory multilateral trading and financial system”. The fundamental challenge is to make the international trading system ensure commercially meaningful and measurable development gains for developing countries from international trade and trade negotiations.

Response and risk in rural ecosystems: from models and plots to defined universes

This essay was prepared as an invited closure of a thematic session on “Scaling and Extrapolation” at the CGTE Conference on “Food and Forestry: Global Change and Global Challenges”. It is addressed to those who prognosticate at the global or other large levels about food and forestry systems, and who naturally confront several problems, and inevitably also some risk. The problems range from conceptual and practical to measuremental and statistical. For other than simplistic models, many constraints apply to procedures used to aggregate from small-scale to large-scale representations of agricultural systems, whether they be biophysical or socioeconomic, especially when uncertainty is explicitly recognized. Model-linking procedures work well in some cases but by no means all. The risks encountered in such work are similarly wide-ranging, depending on the intrinsic uncertainties, context, analyst and audience. These spectrums of problems and risks, along with some suggestions for what practically can be done about them (largely involving ad hoc simulation modeling), are examined from a response-analysis perspective across a range of biophysical and social phenomena pertinent to terrestrial ecosystems. Attention is given to policy applications of scaled-up models.

Overview: The paradoxical relationship between sociology and rational choice

This edition of The American Sociologist brings together discussions of one of the most contentious issues in the discipline?the place of rational choice in sociology. The participants are six distinguished scholars, five of whom are former American Sociological Association presidents. The contribu tors reflect the diversity of views in the discipline and range from quite positive to harshly critical. In this overview, I critically examine the issues that arise in the discussions and provide additional support for the position of several contributors, who argue that even though sociologists have tradi tionally condemned rational choice, many have also implicitly relied upon it as the foundation for their work. This issue of The American Sociologist brings together a remarkable set of essays in which six distinguished scholars, five of whom are former American Sociological Association presidents, address one of the most contentious issues in the discipline, the relationship between sociology and rational choice. These essays derive from a thematic session on the topic, "Rational Choice and Soci ology," that occurred at the American Sociological Association's annual meeting in 1994. Since Talcott Parsons's condemnation of utilitarianism and his effort to erect a barrier separating sociology and economics, the attitude of sociologists toward rational choice has been overwhelmingly negative. These essays may signal a change in this position. Two-thirds of the essays (William Goode, Joan Huber, Matilda White Riley and James Short) discuss rational choice in positive terms. Half of them (Goode, Huber, and Short) go further, arguing that implicit rational

Human Factors at the Department of Energy National Laboratories: An Integrated Lecture-Poster Session

After World War II, a system of national laboratories was created to foster a suitable environment for scientific research. Today, human factors activities are in evidence at most of the nine U.S. Department of Energy multi-program national laboratories as well as at a number of “special program” facilities. In this integrated lecture-poster session, the opening and closing lecture presentations–providing historical and future perspectives, respectively–surround a “thematic poster session” conducted by representatives from six multi-program and two special program laboratories.

Mineral Deposits Studies Group annual meeting, 1987

Report of a meeting of the Mineral Deposits Studies Group held on 14—15 December 1987, at the University of Newcastle upon Tyne. The meeting included a thematic session on the use of stable isotopes in ore genetic studies. In order to take advantage of the location, the annual meeting started with an excursion to visit sites of dolerite-associated mineralization within the North Pennine orefield, led by B. Young of the British Geological Survey. Thirty participants braved the seasonal weather for a most instructive day, and were joined later by a further seventy participants for the subsequent indoor activities of the conference. Details of the thematic session on Stable Isotopes in Ore Genetic Studies have already been given as part of the thematic set of papers published elsewhere in this issue. Other contributions covered a variety of topics. P. R. Ineson (University of Sheffield) reminded the audience of the importance of industrial minerals in his paper on sands which stressed the construction industry's need for good quality, salt-free, sand. Returning to base metals, D. A. C. Manning & E. 1. C. Rae (University of Newcastle upon Tyne) reported the results of experiments to determine the behaviour of Pb-rich feldspars during dissolution, which demonstrate that clastic feldspars within sediments are a significant potential source for Pb. The role of diagenetic processes in ore formation was examined further by M. C. Akhurst (University of Newcastle upon Tyne), who was able to place episodes of mineralization into the diagenetic sequence at Tynagh, and

Stable isotopes in ore genetic studies

A thematic session on the use of stable isotopes in the study of mineral deposits was held as part of the annual meeting of the Mineral Deposits Studies Group in Newcastle upon Tyne on 14th December 1987. Five of the papers presented at the meeting are published here, together with abstracts for six other contributions. The thematic session consisted of 15 papers, with invited contributions from D. T. Rickard and S. M. F. Sheppard. In order of presentation, S. H. Bottrell (University of Leeds) discussed the results of a stable isotope study of the Dolgellau black shale hosted gold mineralization, and demonstrated that the ore fluids were probably derived from an external igneous source, with considerable modification of isotope ratios by interaction with the host rock. P. Eakin (Queen's University of Belfast) then examined evidence for 13 C isotopic fractionation as a consequence of radioactivity within uraniferous hydrocarbons, comparing data for samples from the North Wales orefield with others from Scandinavia and South Africa. This study showed that fractionation effects in excess of 10% may be caused by this process, requiring caution when interpreting C isotope data for organic matter from uraniferous mineral deposits. The following two contributions introduced two recently developed techniques to those within the audience who were not specialist isotope geochemists. S. P. Kelley (with A. J. Boyce, A. E. Fallick, P. J. Hamilton and R. M. McIntyre; SURRC, East Kilbride) described the use of laser microprobe extraction techniques which allow small samples to be studied without the

Fluid inclusion studies

A thematic session on fluid inclusions was held on 15–16 December 1986, at the University of Southampton as part of the annual meeting of the Mineral Deposits Studies Group and was supported by the Applied Mineralogy Group of the Mineralogical Society. Four of the papers are published in this volume (referees: D. H. M. Alderton, A. V. Bromley, R. P. Foster, A. P. Gize, R. A. Ixer, N. J. Jackson, D. A. C. Manning and J. J. Wilkinson), and abstracts are presented for five other contributions. Providing as always an annual forum for the reporting and discussion of mineral deposits research, the 1986 meeting focused in part on fluid inclusion studies in metallogenesis. Opening the meeting, keynote speaker Roedder (Roedder and Howard) referred to a recent study of the Taolin Zn–Pb–fluorite deposit (People's Republic of China) in which homogenization temperatures of 120–200°C and salinity determinations of 0–14 wt% NaCl equiv. were more indicative of low-temperature epithermal mineralization than a Mississippi Valley-type deposit. Some of the data, particularly the homogenization data, differed significantly from the results of an earlier study and were used to emphasize the problems that can be encountered in fluid-inclusion studies. Particular reference was made to the stretching or decrepitation of earlier, lower-Th inclusions by later hotter fluids.later hotter fluids. In the more typical MW-type environment of the Illinois Fluorite District, petroleum-rich and aqueous inclusions were the subject of investigation by Gize and Richardson who observed that the petroleum phase was a strongly

Mineral Deposits Studies Group annual meeting, 1986

Report of a meeting of the Mineral Deposits Studies Group held on 15–16 December 1986, at the University of Southampton. The meeting included a thematic session on fluid inclusions which is reported elsewhere in this volume. Six presentations encompassed epithermal or volcanic-hosted precious-metal deposits and mineralized breccias. The Tambo deposit, near El Indio in Chile, was described by Bernard as a typical hot spring system with bedded sulphates, sulphate sinters, explosion breccias and native sulphur o sulphur overlying hydrothermal breccias and veins. Gold occurred as relatively coarse grains in the silicified wallrocks and also finely dispersed throughout barite. Mixing of ascending auriferous fluids with near-surface acid-sulphate waters was postulated to explain the mineral paragenesis. A similar mixing model was presented by Redwood to account for the disseminated and vein-type Au–Ag–Cu–Pb–Zn mineralization of the Altiplano in Bolivia. The mineralization was associated with silicic flow-dome complexes, and high-K calc-alkaline and shoshonitic magmatism; oxygen and hydrogen isotope data indicated an important magmatic input to the hydrothermal system. A silver-dominated vein-type mineralization comprising silver sulphosalts, native silver, argentite, minor sulphides, calcite, and baryte at Caracoles, northern Chile, was described by Fontbote, Schmidt & Flint, who emphasized the localization of high-grade ore at the intrusive contact between a porphyritic granite and bituminous siltstones and limestones. The role of decompressive shock and hydraulic decrepitation in the generation of hydrothermal breccias and lodes was reviewed by Halls & Allman-Ward. Mineralized hydromagmatic breccias of Hercynian age were identified as the source of the gold
