There are a number of ways to maintain stable levitation and guidance in Maglev through induction. If the secondary currents are unconstrained, the lift to drag ratio is much less than that realizable with constrained currents in a null flux configuration, regardless of whether the source field is superconducting. This paper investigates 2D and 3D boundary element formulations capable of computing forces on such systems. Such systems pose a special challenge because they involve cross‐connected coils having complete flux cancellation when the system is centered. Both 2D and 3D examples are compared to data on a circular test rig.

The purpose of this paper is to demonstrate how Monte Carlo methods can be applied to the solution of field theory problems.

This objective is achieved by building insight from Laplacian field problems. The point solution of a Laplacian field problem can be viewed as the solid angle average of the Dirichlet potentials from that point. Alternatively it can be viewed as the average of the termination potential of a number of random walks. Poisson and Helmholtz equations add the complexity of collecting a number of packets along this walk, and noting the termination of a random walk at a Dirichlet boundary.

When approached as a Monte Carlo problem, Poisson type problems can be interpreted as collecting and summing source packets representative of current or charge. Helmholtz problems involve the multiplication of packets of information modified by a multiplier reflecting the conductivity of the medium.

This method naturally lends itself to parallel processing computers.

This is the first paper to explore random walk solutions for all classes of eddy current problems, including those involving velocity. In problems involving velocity, the random walk direction enters depending on the walk direction with respect to the local velocity.

Problem 1 of the International Workshops for Eddy Current Code Comparison is a hollow cylinder with axis perpendicular to a uniform field. A total of 17 solutions are described and compared with experimental results. Many kinds of codes, both two‐ and three‐dimensional, were found to give satisfactory solutions.

Corporatisation of the New Zealand electricity industry during the 1990s increased the need for improved accountability. The publication of annual reports is one of the prime ways in which organisations meet their accountability obligations. This paper describes the development of a disclosure index from a public accountability perspective and reports the results of its application to the 1999 annual reports of the 33 electricity retail and distribution companies. The index was developed with the support of a panel representing 15 stakeholder groups. It is designed to assess the comprehensiveness (both in extent and quality) of annual report disclosures and incorporates a best‐practice model of annual reporting. Key areas of inadequate disclosure relate to performance measures (financial and non‐financial), segmental information, asset valuation details, and the cost of electricity purchased / generated. Improved disclosure to meet best‐practice guidelines would contribute to improved communication between companies and stakeholders.

Status characteristics and status cues theories posit that those with highly valued status attributes are expected to be more competent and influential than their lower status/skilled task partners. With a focus on beauty and a task cue we term “working smart,” our aim was to specify the combined attributes that led certain women to attain higher status than their female, dyadic task partners.

Using Qualitative Comparative Analysis (QCA), we reanalyzed data from a published study about the impact of women's beauty on a paraverbal measure of status. The approach determines how combined conditions, such as being attractive and task efficient, explain an outcome, such as a status difference, between partners. QCA was paired with qualitative coding of interactants' speech to further interrogate the data.

More task-efficient women always attained higher status than their partners, yet a status difference was stronger if the more efficient partner was beautiful. Although gendered deviance was found to lower women's relative status, it does not constitute a status violation.

Social and Research Implications: Variants of expectation states theory are supported based on our unique QCA approach. Applying QCA as a triangulation tool to evaluate the validity of past findings is a novel usage. Social psychology benefits from QCA's ability to treat micro-level data.

“Working smart” was always associated with higher relative social status but not always beauty or task ability. After 50 years, the “what is beautiful is good” thesis continues to be supported and expanded to “what is beautiful works smarter.”

OUR pages continue the discussion on book‐display, about which all has not been said by any means. The ingenious librarian will always sharpen his wits upon the attracting of readers, and the main problem in the matter is merely: what sort of reader is it most desirable to attract? We do not apologise for this reiteration, because it is the fundamental subject now facing librarians. We are not in the least moved by a comment in a contemporary that we are decrying libraries when we assert, and in spite of him we do assert, that fiction issues nearly all over London show a decline. That decline, we repeat, is due to the slight increase in the employment of readers, and to cheap fiction libraries. What the public librarian has to decide is if he shall compete with such libraries or more definitely diverge from them. If a middle course is preferred—as it usually is by Britons—what is that course? Ultimately, is the educated reader to be the standard for whom the library works, or the uneducated? Or, to put it another way, is the librarian in any way responsible for the quality of the books his community reads? Our readers, young and not so young, are invited to help us to answers to these live questions.

Professional touching behavior (PTB), defined as intentional touching behavior that occurs between organizational members and that falls within the boundaries of appropriateness and professionalism in the workplace, is prevalent in organizations. Scholars from multiple disciplines, including human resources researchers, have acknowledged the importance of physical contact for facilitating interpersonal communication and relationship-building. However, PTB may not only elicit positive reactions from those who receive it but also negative reactions as well, with implications for social dynamics in organizations. PTB can, on the one hand, fulfill employees’ desires for interpersonal connection; at the same time, such physical contact at work can represent a threat to employees’ health. To explain the nature and implications of these divergent effects of receiving PTB, the authors draw upon sociometer theory and behavioral immune system (BIS) theory to model the emotional, cognitive, and physiological processes via which, and the conditions under which, receiving such behavior will result in socially functional responses and prompt subsequent prosocial behavior, and when PTB will be perceived as a health risk and prompt withdrawal behavior. The theoretical framework of this chapter expands our conceptual understanding of the consequences of interpersonal physical contact at work and has important human resources management (HRM) implications for organizational managers.

OWING to the comparatively early date in the year of the Library Association Conference, this number of THE LIBRARY WORLD is published so that it may be in the hands of our readers before it begins. The official programme is not in the hands of members at the time we write, but the circumstances are such this year that delay has been inevitable. We have dwelt already on the good fortune we enjoy in going to the beautiful West‐Country Spa. At this time of year it is at its best, and, if the weather is more genial than this weather‐chequered year gives us reason to expect, the Conference should be memorable on that account alone. The Conference has always been the focus of library friendships, and this idea, now that the Association is so large, should be developed. To be a member is to be one of a freemasonry of librarians, pledged to help and forward the work of one another. It is not in the conference rooms alone, where we listen, not always completely awake, to papers not always eloquent or cleverly read, that we gain most, although no one would discount these; it is in the hotels and boarding houses and restaurants, over dinner tables and in the easy chairs of the lounges, that we draw out really useful business information. In short, shop is the subject‐matter of conference conversation, and only misanthropic curmudgeons think otherwise.
