Abstract
Purpose
Magnetic hysteresis holds significant technical and physical importance in the design of electromagnetic components. Despite extensive research in this area, modeling magnetic hysteresis remains a challenging task that is yet to be fully resolved. The purpose of this paper is to study vector hysteresis play models for anisotropic ferromagnetic materials in a physical, thermodynamical approach.
Design/methodology/approach
In this work, hysteresis play models are implemented to interpret magnetic properties, drawing upon classical rate-independent plasticity principles derived from continuum mechanics theory. By conducting qualitative and quantitative verification and validation, various aspects of ferromagnetic vector hysteresis were thoroughly examined. By directly incorporating the hysteresis play models into the primal formulations using fixed point method, the proposed model is validated with measurements in a finite element (FE) environments.
Findings
The proposed vector hysteresis play model is verified with fundamental properties of hysteresis effects. Numerical analysis is performed in an FE environment. Measured data from a rotational single sheet tester (RSST) are validated to the simulated results.
Originality/value
The results of this work demonstrates that the essential properties of the hysteresis effects by electrical steel sheets can be represented by the proposed vector hysteresis play models. By incorporation of hysteresis play models into the weak formulations of the magnetostatic problem in the h-based magnetic scalar potential form, magnetic properties of electrical steel sheets can be locally analyzed and represented.

Abstract
Investigates the differences in protocols between arbitral tribunals and courts, with particular emphasis on US, Greek and English law. Gives examples of each country and its way of using the law in specific circumstances, and shows the variations therein. Sums up that arbitration is much the better way to gok as it avoids delays and expenses, plus the vexation/frustration of normal litigation. Concludes that the US and Greek constitutions and common law tradition in England appear to allow involved parties to choose their own judge, who can thus be an arbitrator. Discusses e‐commerce and speculates on this for the future.

Abstract
The management of children′s literature is a search for value and suitability. Effective policies in library and educational work are based firmly on knowledge of materials, and on the bibliographical and critical frame within which the materials appear and might best be selected. Boundaries, like those between quality and popular books, and between children′s and adult materials, present important challenges for selection, and implicit in this process are professional acumen and judgement. Yet also there are attitudes and systems of values, which can powerfully influence selection on grounds of morality and good taste. To guard against undue subjectivity, the knowledge frame should acknowledge the relevance of social and experiential context for all reading materials, how readers think as well as how they read, and what explicit and implicit agendas the authors have. The good professional takes all these factors on board.

Abstract
In this article, the fifth in a series on microcomputer software for information storage and retrieval, test results of seven programs are presented and various properties and qualities of these programs are discussed. In this instalment of the series we discuss programs for information storage and retrieval which are primarily characterised by the properties of personal information managers (PIMs), hypertext programs, or best match and ranking retrieval systems. The programs reviewed in this issue are the personal information managers 3by5/RediReference, askSam, Dayflo Tracker, and Ize; Personal Librarian uses best match and ranking; the hypertext programs are Folio Views and the HyperKRS/HyperCard combination (askSam, Ize and Personal Librarian boast hypertext features as well). HyperKRS/HyperCard is only available for the Apple Macintosh. All other programs run under MS‐DOS; versions of Personal Librarian also run under Windows and some other systems. For each of the seven programs about 100 facts and test results are tabulated. The programs are also discussed individually.

Abstract
This conceptual paper explores how the construct of machismo can influence gender‐based discrimination across two cultures; Mexico and the US. First, the relevant literature on machismo is reviewed and the construct clarified. Secondly, evidence is presented which indicates that masculine gender roles are not innate, but rather heavily influenced by cultural factors. Hofstede’s cultural dimensions are used to develop propositions about the effect of masculinity on gender‐based discrimination. We suggest propositions designed to explain how programs aimed at eliminating or reducing gender‐based discrimination might be impacted by high levels of cultural masculinity.

Abstract
ELSEWHERE in this number we list libraries which have Esent us copies of their annual reports which we are glad to have. Now and again we are able to elaborate on these, but in the present issue that has not been possible. We would say, however, that these reports are deserving of the attention of librarians generally, and of students at the library schools. They are records of work in progress, and they do suggest the development of library policy. The best of them are of textbook value.

Abstract
This article is premised on the idea that social networks represent an important, but often overlooked, unit of analysis in management and entrepreneurship studies. The concept of embeddedness, emphasizing the significance of social relationships, is of particular relevance as more and more frequently minorities and immigrants engage in small businessownership. This article borrows from the ethnicity and social network traditions, and offers that an analysis of the ethnic homogeneity of an entrepreneur's strong and weak social ties would be fruitful in gauging entrepreneurial success.
