Abstract

Purpose

This paper aims to propose and establish a set of new benchmark models to investigate and confidently validate the modeling and prediction of total stray-field loss inside magnetic and non-magnetic components under harmonics-direct current (HDC) hybrid excitations. As a new member-set (P21e) of the testing electromagnetic analysis methods Problem 21 Family, the focus is on efficient analysis methods and accurate material property modeling under complex excitations.

Design/methodology/approach

This P21e-based benchmarking covers the design of new benchmark models with magnetic flux compensation, the establishment of a new benchmark measurement system with HDC hybrid excitation, the formulation of the testing program (such as defined Cases I–V) and the measurement and prediction of material properties under HDC hybrid excitations, to test electromagnetic analysis methods and finite element (FE) computation models and investigate the electromagnetic behavior of typical magnetic and electromagnetic shields in electrical equipment.

Findings

The updated Problem 21 Family (V.2021) can now be used to investigate and validate the total power loss and the different shielding performance of magnetic and electromagnetic shields under various HDC hybrid excitations, including the different spatial distributions of the same excitation parameters. The new member-set (P21e) with magnetic flux compensation can experimentally determine the total power loss inside the load-component, which helps to validate the numerical modeling and simulation with confidence. The additional iron loss inside the laminated sheets caused by the magnetic flux normal to the laminations must be correctly modeled and predicted during the design and analysis. It is also observed that the magnetic properties (B27R090) measured in the rolling and transverse directions with different direct current (DC) biasing magnetic field are quite different from each other.

Research limitations/implications

The future benchmarking target is to study the effects of stronger HDC hybrid excitations on the internal loss behavior and the microstructure of magnetic load components.

Originality/value

This paper proposes a new extension of Problem 21 Family (1993–2021) with the upgraded excitation, involving multi-harmonics and DC bias. The alternating current (AC) and DC excitation can be applied at the two sides of the model’s load-component to avoid the adverse impact on the AC and DC power supply and investigate the effect of different AC and DC hybrid patterns on the total loss inside the load-component. The overall effectiveness of numerical modeling and simulation is highlighted and achieved via combining the efficient electromagnetic analysis methods and solvers, the reliable material property modeling and prediction under complex excitations and the precise FE computation model using partition processing. The outcome of this project will be beneficial to large-scale and high-performance numerical modeling.

Abstract

This paper considers firms’ incentive to preserve compatibility between product generations in a duopoly setting. A firm may or may not maintain backward compatibility depending on its first period market share. Firms’ compatibility choices consequently will affect their pricing behaviors. Specifically, it is shown that under certain conditions both firms will preserve compatibility and act as local monopolist in the second period. Hence, backward compatibility becomes a tool for firms to relax second period price competition.

Abstract

Purpose

Higher education institutions (HEIs) frequently overlook the importance of encouraging creative thinking in students. A review of the prevailing practices in a fully online tertiary distance education (DE) institution revealed a lack of learning activities that foster creativity. The study aims to find out whether the creative collaborative group project is a feasible, effective and acceptable learning activity for fostering creativity in students of a fully online graduate-level DE course.

Design/methodology/approach

Seven groups of five to six graduate students each had five weeks to conceptualize, prepare and deliver a creative collaborative group project on lifelong learning using key concepts learned from the course.

Findings

All groups submitted well-crafted creative projects within the given time frame. Reflections on their experience positively correlated with known outcomes associated with creative skills. Students valued the experience and had a better understanding of the concepts. These support the feasibility, effectiveness and acceptability of the project for fostering creativity in a fully online DE institution.

Research limitations/implications

The feasibility, effectiveness and acceptability may vary in different contexts; future iterations in the same and/or other courses are recommended.

Practical implications

The creative collaborative group project is a feasible, effective and acceptable strategy for fostering creativity in online distance education.

Social implications

Creativity can be enhanced through appropriate online collaborative learning activities.

Originality/value

The study adds to the body of literature on the use of creative collaborative group projects to foster creativity in HEIs.

Abstract

Purpose

The purpose of this paper is to explore how firms can mitigate knowledge hiding behavior among their managers.

Design/methodology/approach

This study employs a multiple case study methodology by studying nine UAE based firms. Furthermore, 26 semi-structured interviews with senior managers are undertaken.

Findings

Based on the qualitative interviews and comprehensive data analysis, results unveil six strategies that firms can opt for in order to mitigate knowledge hiding behavior among managers (reducing chain of command, developing informal interaction among managers, introducing and implementing incentive policy, initiating easy performance appraisal, encouraging higher interdependency among managers and introducing open space work stations).

Research limitations/implications

This study has some limitations. First, the results of this study are not generalizable to a broader population. Second, this study explores behavioral patterns with respect to United Arab Emirates culture only. Second, the results presented in this study should be tested.

Practical implications

Firms can use the findings from this study to understand strategies that can help them to mitigate the knowledge hiding behavior of managers.

Originality/value

This study contributes to knowledge hiding literature by revealing strategies, which discourages knowledge hiding behavior in firms.

Abstract

Purpose

The purpose of this paper was to investigate the role of the body in the vocational anticipatory socialization (VAS) processes of classical musicians.

Design/methodology/approach

Using grounded theory, the paper analyzed semi-structured interviews with 48 musicians (27 children; 21 parents) to understand how classical musicians’ bodies intermediate the meaning of work. The Aristotelian concepts of potentiality and actuality frame this study.

Findings

The paper reveals that: “tuning” bodies is as important as tuning instruments (body as object of work), and diseases, occupational injuries, and accidents pose challenges to both health and performance (body as obstacle).

Research limitations/implications

Theoretically, the paper contributes the notion that phases of VAS are fused not just through cognitive and relational processes, but also through embodied learning for classical musicians.

Practical implications

At the practical level, the paper reminds that the body is an important source of vocational socialization information.

Originality/value

The paper is filling a gap in organizational literature, which has under addressed the materiality of the body.

Abstract

The strain energy method for the analysis of pin‐jointed redundant frameworks is expressed in matrix form suitable for solution on electronic computers. This is illustrated by its application to a zero‐length launcher framework having sixty‐three members, nine of which are redundant, using the Ferranti Pegasus computer. It is concluded that a framework must be reasonably complex before the use of this method is justified but that problems of greater complexity than would normally be attempted can readily be solved.

Abstract

Purpose

This chapter explores the recent trend in libraries: that of the establishment of spaces specifically set aside for creative work. The rise of these dedicated creative spaces is owed to a confluence of factors that happen to be finding their expression together in recent years. This chapter examines the history of these spaces and explores the factors that gave rise to them and will fuel them moving forward.

Methodology/approach

A viewpoint piece, this chapter combines historical research and historical/comparative analyses to examine the ways by which libraries have supported creative work in the past and how they may continue to do so into the 21st century.

Findings

The key threads brought together include a societal recognition of the value of creativity and related skills and attributes; the philosophies, values, and missions of libraries in both their long-standing forms and in recent evolutions; the rise of participatory culture as a result of inexpensive technologies; improved means to build community and share results of efforts; and library experience and historical practice in matters related to creativity. The chapter concludes with advice for those interested in the establishment of such spaces, grounding those reflections in the author’s experiences in developing a new creative space at Virginia Commonwealth University.

Originality/value

While a number of pieces have been written that discuss the practicalities of developing certain kinds of creative spaces, very little has been written that situates these spaces in larger social and library professional contexts; this chapter begins to fill that gap.

Abstract

Purpose

Mobile computing devices are a significant access point for information activities. Theories and models of human information behaviour have developed over several decades but have not considered the role of the user's computing device in digital information interactions. The purpose of this paper is to explore the information behaviours of young adults when they are given unlimited access to mobile tablet devices.

Design/methodology/approach

As information tasks, behaviours and communities shift into digital environments, a researcher of these phenomena is required to mirror that movement with techniques that allow a full exploration of human behaviour and interaction in the online world. Following Kozinets (2009), “netnography” (ethnography in online communities) is applied in this study and all data are collected online from within a community of iPad users, established for the research purpose.

Findings

This study reveals that access to mobile tablet devices creates significant shifts in the behaviours of young adults whose lives are immersed in digital information. Mobile tablet devices establish the potential for constant access to digital information and that opportunity is grasped by the participants in this research. Extensive use of mobile device applications or “apps” establishes a more selected and restricted view of information than that encountered in the open and expansive World Wide Web.

Originality/value

This paper invites extension to human information behaviour theories and models to include a consideration of computing access device and of new mobility and constancy of access – all of which changes the circumstances and behaviour of the information actor.

Abstract

Purpose

The purpose of this paper is to explore young people’s conceptions of political information. The study sought to identify what political information sources young people encounter, how they construe these sources and the messages they communicate, and how the information experiences of young people may be better understood to inform information literacy interventions to support the development of political agency.

Design/methodology/approach

Using personal construct theory as a conceptual framework, repertory grid (RG) interviews were used to explore the different ways in which 23 young people aged 14-15 from a town in Northern England conceive of political information and how they evaluate its quality and authority.

Findings

The study identified the sources of information young people engage with for finding and receiving what they understand as political information. The results from the RG interviews indicated that young people use a wide range of sources of political information to become informed about politics and the world around them. These sources of information include family, friends, teachers, television news, newspapers, radio shows, comedy shows, social media and community meetings. Participants were aware that they passively encounter information sources as well as actively engage in debate and discussion with other sources. Some participants had difficulty critically evaluating the political information sources they encounter. The nature of young people’s experiences of political information varied greatly. The degree of complexity in the experiences of political information varied not only between participants but was also dependent on their particular relationship with the information sources under scrutiny.

Research limitations/implications

The paper has implications for personal construct analysis as a research approach broadly, from the point of view of its use within library and information science research. It is the first study to apply the personal construct approach to the study of young people’s political information use and to consider implications for information literacy support that would have been difficult to access using other approaches.

Practical implications

The paper provides insight into an understudied area; that of young people’s conceptions of political information. This insight may be used to inform the improvement of political information provision and information literacy support for young people.

Social implications

A deeper understanding of the different ways in which young people identify, engage with and use information for political purposes may contribute to a clearer understanding of young people’s information needs, ideally leading to improved political education and a strengthened democratic process.

Originality/value

The paper explores a relatively under-researched area of library and information science research, and does so using a relatively under-used method in the domain. Insights into the perceived characteristics of different sources of political information are novel and contribute to the development of information behaviour and information literacy fields in terms of information for empowerment and democracy.
