Abstract

Purpose

The purpose of the paper is to provide a comparison of first‐ and second‐order two dimensional finite element models for evaluating the electromagnetic properties and calculating AC loss in high‐temperature superconductor (HTS) coated conductors.

Design/methodology/approach

The models are based on the two‐dimensional (2D) H formulation, which is based on directly solving the magnetic field components in 2D. Two models – one with a minimum symmetric triangular mesh and one with a single‐layer square mesh – are compared based on different types of mesh elements: first‐order (Lagrange – linear) and second‐order (Lagrange – quadratic) mesh elements, and edge elements.

Findings

The number and type of mesh elements are critically important to obtain the minimum level of discretization to achieve accurate results. Artificially increasing the superconductor layer and choosing a minimum symmetric mesh with triangular edge elements can provide a sufficiently accurate estimation of the hysteretic superconductor loss for a transport current.

Originality/value

This paper describes how the selection of mesh type and number of elements affects the computation speed and convergence properties of the finite element model using two different types of meshing. It offers an insight into the different factors modelers must consider when modeling HTS coated conductors and the methods that may be applied when extending the model to complex device geometries, such as wound coils.

Abstract

This chapter conducts a systematic comparison of behavioral economics’s challenges to the standard accounts of economic behaviors within three dimensions: under risk, over time, and regarding other people. A new perspective on two underlying methodological issues, i.e., inter-disciplinarity and the positive/normative distinction, is proposed by following the entanglement thesis of Hilary Putnam, Vivian Walsh, and Amartya Sen. This thesis holds that facts, values, and conventions have inter-dependent meanings in science which can be understood by scrutinizing formal and ordinary language uses. The goal is to provide a broad and self-contained picture of how behavioral economics is changing the mainstream of economics.

Abstract

Behavioral economics poses a challenge for the welfare evaluation of choices, particularly those that involve risk. It demands that we recognize that the descriptive account of behavior toward those choices might not be the ones we were all taught, and still teach, and that subjective risk perceptions might not accord with expert assessments of probabilities. In addition to these challenges, we are faced with the need to jettison naive notions of revealed preferences, according to which every choice by a subject expresses her objective function, as behavioral evidence forces us to confront pervasive inconsistencies and noise in a typical individual’s choice data. A principled account of errant choice must be built into models used for identification and estimation. These challenges demand close attention to the methodological claims often used to justify policy interventions. They also require, we argue, closer attention by economists to relevant contributions from cognitive science. We propose that a quantitative application of the “intentional stance” of Dennett provides a coherent, attractive and general approach to behavioral welfare economics.

Abstract

The new frontier: Go East, young man. Go East. Searching for business opportunities in Eastern Europe. In the March issue of The Intelligent Enterprise, John Ainslie predicts that the 90s will be a decade of disaster for the new democracies of Eastern Europe. The fledgling governments could be hit by up to 50 million Soviet economic refugees, according to Czech President Vaclav Havel, and Ainslie wonders if their fragile economies will be able to handle the strain.

Abstract

Purpose

This paper aims to evaluate the success of a Wikipedia editing assessment designed to improve the information literacy skills of a cohort of first-year undergraduate health sciences students.

Design/methodology/approach

In this action research case study (known hereafter as “the project” to differentiate this action research from the students’ own research), students researched, wrote and published Wikipedia articles on Australia-centric health topics. Students were given a pre- and post-test to assess levels of self-confidence in finding, evaluating and referencing information. Student work was also analysed in terms of article length and quantity and the type of information sources used.

Findings

Tests revealed that students’ self-confidence in their information literacy skills improved overall. Analysis of student work revealed that students wrote longer articles and incorporated more references than expected. References used were of appropriate quality relevant to the article despite minimal instructions.

Originality/value

There are few studies that investigate information literacy development through Wikipedia editing in Australian universities. This study shows that Wikipedia editing is an effective way to carry out student assessment prior to essay writing and an innovative platform to improve information literacy skills in undergraduate students.

Abstract

An assumption made in many applications of stated preference modeling is that preferences remain stable over time and over multiple exposures to information about choice alternatives. However, there are many domains where this assumption can be challenged. One of these is where individuals learn about new products. This paper aims to test how attribute preferences as measured in an experimental choice task shift when respondents are exposed to new product information. The paper presents results from a study investigating consumer preferences for a new consumer electronics product conducted among 400 respondents from a large consumer panel. All respondents received several choice tasks and were then able to read additional information about the new product. After this they completed an additional set of choice tasks. All choices were from pairs of new product alternatives that varied across eight attributes designed according to an orthogonal plan. Using heteroscedastic logit modeling, the paper analyses the shifts in attribute utilities and scale variances that result from the exposure to product information. Results show that as respondents become better informed about a new attribute the attribute has a greater influence on their choices. In addition a significant shift in scale variance is observed, suggesting an increase in preference heterogeneity after information exposure.

Abstract

In the Annual Report of the General Purposes Committee of the Middlesex County Council for the year ending March 31, 1909, it is stated that inquiries were made as to the action taken under the Dairies, Cowsheds, and Milkshops Orders of 1885 and 1899 by the thirty‐six district councils in the county, the object of such action being the detection of cows suffering from tuberculosis of the udder. It might be thought that by this time the necessity for putting these orders into force had been thoroughly proved. The Royal Commission on Tuberculosis made a definite statement to the effect that milk derived from tuberculous cattle is one of the principal causes of tubercular disease in the human subject, and, apparently there seems to be some disposition on the part of local authorities to make tuberculosis notifiable. The Public Health (Tuberculosis) Regulations, 1908, which came into force at the beginning of 1909, require that all cases of pulmonary tuberculosis are to be notified to the sanitary authority if the patients are receiving treatment from the Poor Law medical officers. Large sums are spent every year throughout the country on the upkeep of sanatoria with the object of curing cases of tubercle, if possible, but, in any case, of alleviating the sufferings of those afflicted with tuberculosis. On all sides, in fact, it is now recognised that the most energetic measures are necessary in order to combat this terrible disease. It appears from the figures given in the Report referred to that in twenty‐three out of the thirty‐six districts. “No veterinary examinations of cows were made on behalf of the local authorities!” The statement is not made the subject of comment, but we hardly think that the county authorities can regard the results of their enquiry as satisfactory. The Report was apparently presented to the County Council on July 22 last, so that up to that time, at least, it would seem that these twenty‐three districts, in a county with about one million inhabitants, are governed, so far as sanitary matters go, by people who consider themselves qualified to hold opinions diametrically opposed to those held by experts and based on the best scientific evidence at present available.

Abstract

Publishing and printing have travelled a very long way in the last 150 years. There had been no basic changes in the working of the printing press between its first inception and the early nineteenth century. In those days each letter was both cast and set by hand. The maximum speed of an expert founder was about six letters per minute. This works out at more than half a day's work for a page.

Abstract

This chapter draws from a three-year ethnographic study focused on the educational and community interactions among working- and middle-class ethnic Chinese immigrants in a mid-western town in the United States. Aihwa Ong (1999) argues that “Chineseness” is a fluid, cultural practice manifested within the Chinese diaspora in particular ways that relate to globalization in late modernity, immigrants’ cultural background, their place in the social structure in their home society, and their new social class status in the context they enter. The study extends research focused on the complexities of social reproduction within larger global flows of Chinese immigrants. First, we describe how Chinese immigrants’ social status in their countries of origin in part shapes middle and working-class group’s access to cultural capital and positions in the social structure of their post-migration context. Second, we trace groups’ negotiation of their relational race and class positioning in the new context (Ong, 1999) that is often invisible in the processes of social reproduction. Third, we describe how both groups must negotiate national, community, and schooling conceptions of the model minority concept (Lee, 1996) that shapes Asian-American’s lived realities in the United States; yet the continuing salience of their immigrant experience, home culture, and access to cultural capital (Bourdieu, 2007) means that they enact the “model minority” concept differently. The findings suggest the complexity of Chinese immigrants’ accommodation of and resistance to normative ideologies and local structures that cumulatively contribute to social reproduction on the basis of class.
