Competitive Markets and Aggregate Information
No full textThis paper shows that a competitive market structure is identically efficient to a Walrasian rational expectations market when risk-averse agents base trades only on unbiased private signals. Because price reflects the complete set of market information, it is a sufficient statistic. The economic role of competing market makers is thus to aggregate information efficiently.Market Structure
Edward Baigent : a pioneer Nelson settler, businessman, and politician : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in History at Massey University
No full textEdward Baigent arrived in New Zealand almost 140 years ago, and except for a few months in Nelson, spent his entire life in Wakefield. Unfortunately neither Edward Baigent nor any of his children seem to have kept diaries, or been prolific letter writers. The information this thesis is based upon, does thus come almost entirely from early newspaper articles, diaries of Baigent's contemporary settlers, and old ledgers and journals, dating back to 1870, which were found by chance last year in the demolition of an old building on Baigents' Rutherford Street property. The completion of this thesis would not have been possible if not for the willing assistance I have had from a number of people. Special thanks must go to Mr John Bush, who began collecting information relating to the Baigent family several years ago, with the intention of eventually writing a family/company history. With characteristic unselfishness, Mr Bush passed on to me all the material he had accumulated, and I am extremely grateful for the initial help he provided. To Mrs M. Palmer, a great grand-daughter of Edward Baigent, I also extend my special thanks. Mrs Palmer has always taken a great deal of interest in the Baigent family, and wherever possible, has been of great assistance to me. Nelson is fortunate that early events were faithfully recorded by newspaper reporters almost immediately settlement was commenced. The Nelson Examiner and New Zealand Chronicle which began in 1842 and continued until 1874, provided much valuable information on the early years of settlement in the Nelson Province. An almost complete file of this paper is available at the Nelson Public Library, and to the staff of the Library I wish to record my thanks

Management of budbreak promoters in 'Baigent' apple trees under hail net in southern Brazil
No full textA utilização de indutores de brotação é uma das estratégias de manejo que viabilizam o cultivo de macieiras 'Baigent', em larga escala, no Brasil. Tais compostos minimizam os problemas fisiológicos decorrentes do comum déficit de frio hibernal para a plena superação da dormência em grande parte dos locais de cultivo do Sul do país. O manejo padrão envolve uma única aplicação de cianamida hidrogenada (CH) ou Erger® associados a outros compostos, nas concentrações atualmente preconizadas. Entretanto, resultados insatisfatórios podem ser observados em alguns anos, sobretudo sob quaisquer condições que possam intensificar o vigor, a exemplo de telas antigranizo. O objetivo deste trabalho foi avaliar alternativas no manejo de CH e Erger® para otimizar a indução à brotação da cultivar Baigent sob tela antigranizo no Sul do Brasil. Dois experimentos foram conduzidos em pomar comercial, em Vacaria/RS. O material vegetal consistiu em plantas de 12 anos sobre porta-enxerto 'M.9', conduzidas em líder central e sob tela preta. Durante as safras de 2017/18 e 2018/19, em diferentes plantas, foram acessadas fenologia, brotação de gemas, frutificação, produção e qualidade de frutos, nas porções inferior e superior da copa - cada uma 50% do total. O primeiro experimento envolveu a aplicação sequencial de Erger® junto a óleo mineral (OM), isto é, uma segunda pulverização. Para tal, foram avaliados os tratamentos: 1. Testemunha (sem aplicação); 2. Erger® 1,5% + OM 3,5%; 3. Erger® 1,5% + OM 3,5% (Aplicação 1 - AP1) e (Aplicação 2 - AP2); 4. Erger® 3% + Calcinit® 3%; 5. Erger® 3% + Calcinit® 3% (AP1) e Erger® 1,5% + OM 3,5% (AP2); 6. CH 0,34% + OM 3,5% e 7. CH 0,34% + OM 3,5% (AP1) e Erger® 1,5% + OM 3,5% (AP2). O uso de Erger® 1,5% + OM 3,5% (AP1) e (AP2) proporcionou os maiores níveis de brotação, sendo similar apenas às aplicações com CH + OM. O segundo experimento compreendeu a avaliação de diferentes concentrações de CH - 0%, 0,17%, 0,34%, 0,51%, 0,69% e 0,86%, associadas a OM 3,5%, em conjunto a um tratamento sem aplicação. A brotação de gemas axilares foi intensificada por CH acima de 0,17% + OM 3,5%, sobretudo a partir de insuficiente acúmulo de baixas temperaturas durante o inverno. Os maiores resultados foram induzidos por CH acima de 0,51%. A frutificação não foi influenciada por CH + OM 3,5%, assim como a produção e a qualidade dos frutos. Resposta similar foi obtida para a brotação em ambas as porções da copa, exibindo a superior maior frutificação, nos dois ensaios. Intensificações no crescimento dos ramos, especialmente quando em diferentes magnitudes ao longo da copa, demandam maiores estudos, sobretudo com as mesmas plantas em safras subsequentes. De maneira geral, o uso de Erger® 1,5% + OM 3,5% (AP1) e (AP2) é uma alternativa ao respectivo uso único e Erger® 3% + Calcinit® 3%, bem como CH acima de 0,34% + OM 3,5% é para CH 0,34% + OM 3,5% (padrão) visando a otimização da indução à brotação de macieiras 'Baigent' sob tela antigranizo nas condições de estudo no Sul do Brasil.The application of budbreak promoters is one of the management strategies that allow large-scale cultivations of 'Baigent' apple trees in Brazil. These compounds minimize the physiological problems caused by the common lack of cold in most growing areas in the southern region. As standard use, hydrogen cyanamide (HC) or Erger® are associated with other compounds in a single application in accordance with currently recommended concentrations. However, unsatisfactory results have been observed in some years, especially under any conditions that can increase vigor, such as hail nets. This study aimed to evaluate alternatives in the management of HC and Erger® to optimize budbreak induction of the cultivar Baigent under hail net in southern Brazil. Two experiments were conducted in a commercial orchard in Vacaria/RS. Twelve-year-old plants grafted on 'M.9' rootstock, trained as a central leader and under black hail net were selected as plant material. During the 2017/18 and 2018/19 growing seasons, in different individuals, variables related to phenology, budbreak, fructification, fruit production, and quality were analyzed in the lower and upper portions of the canopy - each 50% of the total. The first experiment involved a sequential application of Erger® in combination with mineral oil (MO), i.e., a second application. Treatments were: 1. Control (no application); 2. Erger® 1.5% + MO 3.5%; 3. Erger® 1.5% + MO 3.5% (Application 1 - AP1) and (Application 2 - AP2); 4. Erger® 3% + Calcinit® 3%; 5. Erger® 3% + Calcinit® 3% (AP1) and Erger® 1.5% + MO 3.5% (AP2); 6. HC 0.34% + MO 3.5% and 7. HC 0.34% + MO 3.5% (AP1) and Erger® 1.5% + MO 3.5% (AP2). Using Erger® 1.5% + MO 3.5% (AP1) and (AP2), the highest budbreak percentages were provided, similar only to those of HC + MO treatments. Different concentrations of HC - 0%, 0.17%, 0.34%, 0.51%, 0.69% and 0.86%, combined with MO 3.5%, were evaluated with a control (no spraying) treatment in the second experiment. Axillary budbreak was intensified by HC above 0.17% + MO 3.5%, particularly with low chilling accumulation during winter. With HC above 0.51%, the highest increases were observed. There was no influence of HC + MO 3.5% on fructification, fruit production/quality, and the same response occurred for budbreak in both canopy portions. But the upper one presented higher fructification in both trials. Intensifications in the growth of shoots, especially at different magnitudes along the canopy, demand further studies, especially with the same plants in subsequent seasons. Overall, the use of Erger® 1.5% + MO 3.5% (AP1) and (AP2) is an alternative to its single use and Erger® 3% + Calcinit® 3%; and HC above 0.34% + MO 3.5% can substitute HC 0.34% + MO 3.5% (standard) to optimize budbreak induction of 'Baigent' apple trees under hail net in these conditions of southern Brazil

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Do selective cyclo-oxygenase-2 inhibitors and traditional non-steroidal anti-inflammatory drugs increase the risk of atherothrombosis? Meta-analysis of randomised trials.
No full textOBJECTIVE: To assess the effects of selective cyclo-oxygenase-2 (COX 2) inhibitors and traditional non-steroidal anti-inflammatory drugs (NSAIDs) on the risk of vascular events. DESIGN: Meta-analysis of published and unpublished tabular data from randomised trials, with indirect estimation of the effects of traditional NSAIDs. DATA SOURCES: Medline and Embase (January 1966 to April 2005); Food and Drug Administration records; and data on file from Novartis, Pfizer, and Merck. REVIEW METHODS: Eligible studies were randomised trials that included a comparison of a selective COX 2 inhibitor versus placebo or a selective COX 2 inhibitor versus a traditional NSAID, of at least four weeks' duration, with information on serious vascular events (defined as myocardial infarction, stroke, or vascular death). Individual investigators and manufacturers provided information on the number of patients randomised, numbers of vascular events, and the person time of follow-up for each randomised group. RESULTS: In placebo comparisons, allocation to a selective COX 2 inhibitor was associated with a 42% relative increase in the incidence of serious vascular events (1.2%/year v 0.9%/year; rate ratio 1.42, 95% confidence interval 1.13 to 1.78; P = 0.003), with no significant heterogeneity among the different selective COX 2 inhibitors. This was chiefly attributable to an increased risk of myocardial infarction (0.6%/year v 0.3%/year; 1.86, 1.33 to 2.59; P = 0.0003), with little apparent difference in other vascular outcomes. Among trials of at least one year's duration (mean 2.7 years), the rate ratio for vascular events was 1.45 (1.12 to 1.89; P = 0.005). Overall, the incidence of serious vascular events was similar between a selective COX 2 inhibitor and any traditional NSAID (1.0%/year v 0.9%/year; 1.16, 0.97 to 1.38; P = 0.1). However, statistical heterogeneity (P = 0.001) was found between trials of a selective COX 2 inhibitor versus naproxen (1.57, 1.21 to 2.03) and of a selective COX 2 inhibitor versus non-naproxen NSAIDs (0.88, 0.69 to 1.12). The summary rate ratio for vascular events, compared with placebo, was 0.92 (0.67 to 1.26) for naproxen, 1.51 (0.96 to 2.37) for ibuprofen, and 1.63 (1.12 to 2.37) for diclofenac. CONCLUSIONS: Selective COX 2 inhibitors are associated with a moderate increase in the risk of vascular events, as are high dose regimens of ibuprofen and diclofenac, but high dose naproxen is not associated with such an excess
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
