An interactive approach to learning economics: The WinEcon package

Under the TLTP initiative, the Economics Consortium is developing an interactive computer‐based learning package called WinEcon. The package is directed at first‐year economics undergraduates, particularly those taking economics as a supplementary course. Using recent technological developments, the aim is both to facilitate a further increase in student numbers without a proportionate increase in teaching staff, and to provide a better method of student learning. Some key elements of WinEcon are set out in this paper and demonstrated by screens produced at Leicester University. Methods of presenting textual information that give the user control over accessing it are described. For learning difficult concepts, a visual active learning approach is discussed. It involves user interaction and step‐by‐step analysis. The importance of flexibility and choice is emphasized, and the capacity of the computer to assist in deepening and consolidating learning is shown

Dolomitization Processes in Hydrocarbon Reservoirs: Insight from Geothermometry Using Clumped Isotopes

Clumped isotopes geothermometry was applied to two dolomitic hydrocarbon reservoirs. Results indicate that late burial dolomitization occurred at ~110°C in the Albian Pinda dolostone (offshore Angola) and ~90°C in the Mano-Meillon dolostone (Aquitaine Basin, France), and did not continue on during subsequent burial/thermal evolution to present-day conditions (150-160°C). This study illustrates the great potential of the clumped isotopes approach to help unravel dolomitization processes in hydrocarbon reservoirs

Further education in transition

This paper provides an overview of the national perspective in further education (FE) developments in Information and Learning Technology (ILT) since 1992, from the unique perspective of a number of key staff members at the British Educational Communications and Technology Agency (Becta) and a member of staff with a role in quality improvement in the Further Education Funding Council (FEFC). It sets in context the research reported in this section in the papers by Cockrill et al. and Caven‐Atack

Predicting the steady state thickness of passive films in order to prevent degradations of implant

Some implants have approximately a lifetime of 15 years. The femoral stem, for example, should be made of 316L/316LN stainless steel. Fretting corrosion, friction under small displacements, should occur during human gait, due to repeated loadings and un-loadings, between stainless steel and bone for instance. Some experimental investigations of fretting corrosion have been practiced. As well known, metallic alloys and especially stainless steels are covered with a passive film that prevents from the corrosion and degradation. This passive layer of few nanometers, at ambient temperature, is the key of our civilization according to some authors. This work is dedicated to predict the passive layer thicknesses of stainless steel under fretting corrosion with a specific emphasis on the role of proteins. The model is based on the Point Defect Model (micro scale) and an update of the model on the friction process (micro-macro scale). Genetic algorithm was used for finding solution of the problem. The major results are, as expected from experimental results, albumin prevents from degradation at the lowest concentration of chlorides; an incubation time is necessary for degrading the passive film; under fretting corrosion and high concentration of chlorides the passive behavior is annihilated

A clinical report on a form of leucorrhoea found in relation to certain rheumatic states

A clinical investigation was made into 92 cases giving a history of leucorrhoea commencing between the ages of 11 years and 20 years, viz. Group A, 82 cases, who were women of child-bearing age, and Group B, 10 cases, who were school-girls. A control series for Group A, Group C (82 cases), was also examined.As a result the following conclusions were drawn: (i) This form of leucorrhoea is not primarily caused by local genital-tract infections, though these may be superimposed upon it. (ii) The discharge arises in the vagina as a result of some alteration in the "trophicity. of its lining mucous membrane and consists chiefly of desquamated vaginal epithelium. (iii) The occurrence of one or more of the manifestations of rheumatism is seen in over 75% of patients complaining of this symptom, (iv) Other debilitating or toxic conditions, such as tuberculosis, chronic tonsillar sepsis, and extensive burns, may be associated with it

Bacterial Foodborne Disease: Medical Costs and Productivity Losses

Microbial pathogens in food cause an estimated 6.5-33 million cases of human illness and up to 9,000 deaths in the United States each year. Over 40 different foodborne microbial pathogens, including fungi, viruses, parasites, and bacteria, are believed to cause human illnesses. For six bacterial pathogens, the costs of human illness are estimated to be $9.3-$12.9 billion annually. Of these costs, $2.9-$6.7 billion are attributed to foodborne bacteria. These estimates were developed to provide analytical support for USDA's Hazard Analysis and Critical Control Point (HACCP) systems rule for meat and poultry. (Note that the parasite Toxoplasma gondii is not included in this report.) To estimate medical costs and productivity losses, ERS uses four severity categories for acute illnesses: those who did not visit a physician, visited a physician, were hospitalized, or died prematurely. The lifetime consequences of chronic disease are included in the cost estimates for E. coli O157:H7 and fetal listeriosis.cost-of-illness, foodborne pathogens, lost productivity, medical costs, Food Consumption/Nutrition/Food Safety, Health Economics and Policy,

User-Fee Financing of USDA Meat and Poultry Inspection

USDA's Food Safety and Inspection Service (FSIS) finances about 13.5 percent of its budget outlays through user fees for overtime and unscheduled meat and poultry inspections. User fees play an increasingly important role in financing government programs, and FSIS has frequently requested expanded authority to charge user fees for more of its operations. Congress has consistently rejected the FSIS requests and has placed important restrictions on fees and the uses of fee revenue at those agencies that have been granted more extensive user fee authority. This report surveys the application of user-fees for financing meat and poultry inspection programs in other countries; reviews user-fee systems in other Federal agencies, particularly those with food and agricultural missions or regulatory responsibilities; and discusses the relevant economics literature on the use and design of user fees. Finally, we suggest several elements that should underlie the structure of user fees for meat and poultry inspection, should such a program be introduced. euser fees, meat inspection, public finance, Livestock Production/Industries, Public Economics,
