Authors: Agheb E. , Hashemi E. , Mousavi S.A. , Hoidalen H.K. 
Published: February 2012

PurposeThe purpose of this paper is to study very fast transient overvoltages (VFTOs) in the secondary winding of air‐cored Tesla transformers and also study the resulting electric field stresses.Design/methodology/approachAn exhaustive model based on Multi‐conductor Transmission Lines (MTLs) theory has been used. The governing telegraphist's equations have been solved by Finite Difference Time Domain (FDTD) method.FindingsThe results demonstrated that there are some overvoltages at the end and middle turns that should be considered in insulation design. The magnitudes of these overvoltages are several times more than the steady state value of the corresponding turn which cause very high electric field stresses.Originality/valueThe paper describes results obtained from an original and innovative implementation of FDTD method in transmission line modelling and is applied properly to air‐cored pulse transformers.

Authors: Inui Shigeru , Yamada Tatsuro , Horiba Yosuke , Hashimoto Minoru 
Published: February 2012

PurposeIn the trend from mass production to mass customization, more flexible production systems are required. In the clothing field, many studies about automatization of sewing processes have been done into producing small amounts of various kinds of products. The purpose of this paper is to propose a versatile guiding mechanism of a cloth for an automatic sewing system.Design/methodology/approachReal sewing processes were referenced for the mechanism, and curved stitch is formed holding a point on a cloth. This mechanism consists of a solenoid for holding a cloth and a roller to prevent deformation of the cloth. When a cloth is sewn with the mechanism, the trajectory of the stitch is unstable because of anisotropy of a cloth. A precise trajectory was obtained by adding a device to control the pressure of the roller for holding a cloth and keeping a tension properly applied to a cloth.FindingsIt was found out that shearing property is the most related to the stability of sewing trajectory. If the tension for guidance applied to a cloth is constant, deformation of the cloth was observed and it was the cause of unstableness of sewing trajectory. By controlling the tension for guidance applied to a cloth properly according to the direction of the cloth, precise sewing trajectory was obtained.Originality/valueThere have been some studies in which sewing conditions were dynamically controlled according to the mechanical properties of a cloth. To these studies, here it was proposed that sewing conditions were kept constant by controlling the guidance of a cloth according to its mechanical properties.
Novel method of weaving three‐dimensional shapes
Authors: Bhattacharya S.S. , Koranne Milind 
Published: February 2012

PurposeDevelopment of a technique for weaving seamless three‐dimensional shapes directly on loom is an essential step in producing seamless woven garments. The purpose of this paper is to report a new approach to weaving seamless three‐dimensional shapes.Design/methodology/approachSpacing of warp and weft threads varies in shape region. Reeds with shaped reed wires are developed to change spacing of warp threads. Interlacement pattern of warp and weft threads is selected that assists in changing spacing of threads. The new approach of weaving three‐dimensional shapes in folded form is developed, that offers advantages over weaving shape in erect form.FindingsThe main findings were mathematical determination of shapes of reed wires to produce a three‐dimensional woven shape and weaving shape in folded form.Originality/valueThe paper demonstrates how three‐dimensional shapes are woven in folded form without the need of eliminating ends.
Introducing undergraduate students to school leadership concepts
Authors: Eacott Scott 
Published: February 2012

PurposeThis paper aims to investigate the role of an under‐graduate educational leadership in introducing students to the complexity of school leadership practice.Design/methodology/approachTheoretically informed by Bourdieuian social theory and drawing on a questionnaire with a cohort of students, the paper evaluates a course in relation to achieving its outcomes.FindingsAn analysis of student responses indicates that the course did introduce students to school leadership practice and assist in the construction of a school leadership disposition.Research limitations/implicationsThe theoretical resources used in the paper have significant implications for how researchers conceive of school leadership practice. Therefore, this paper may be the basis of further work.Practical implicationsThe findings of this work have implications for teacher educators and specifically universities. From this paper, the inclusion of an educational leadership course in under‐graduate programs should become more the norm rather than the exception.Originality/valueThis paper has value in two unique ways. First, there has been very little work undertaken on the role of educational leadership courses in under‐graduate programs and in the context of increased political attention and no formal pre‐requisites for the principalship in Australia, this work is both timely and significant. Second, this paper works with a sophisticated notion of school leadership practice and its location using social theory, a perspective that is uncommon in much of the literature on educational leadership.
Principal selection panels: strategies, preferences and perceptions
Authors: Walker Allan , Kwan Paula 
Published: February 2012

PurposeThe purpose of this article is to report a study of the strategies members of principal selection panels use to select the best candidate for a principal position.Design/methodology/approachThe study draws on both qualitative and quantitative data. The quantitative analysis drawn on data collected from school supervisors and school principals confirmed a four‐factor structure and qualitative interview data was used to supplement findings.FindingsIn order of importance the strategies employed by selection panels were: panel professionalism, the interview, making the cut and pre‐interview.Practical implicationsFindings indicate that the selection component of principal recruitment remains at best an uncertain science. Tensions endure between beliefs and perceptions of panel members from different backgrounds. These include beliefs about competence and level of involvement in important activities such as short‐listing. Relational ties, religious affiliation and values congruence are important to members of selection panels, but we are unsure of the influence these have on the quality of successful applications. It seems that at a minimum they may reduce the pool of “real” applicants.Originality/valueThe study provides useful information on the strategies members of principal selection panels use to select the best candidate for a principal position.
Who should rank our journals … and based on what?
Authors: Cherkowski Sabre , Currie Russell , Hilton Sandy 
Published: February 2012

PurposeThis study aims to establish the use of active scholar assessment (ASA) in the field of education leadership as a new methodology in ranking administration and leadership journals. The secondary purpose of this study is to respond to the paucity of research on journal ranking in educational administration and leadership.Design/methodology/approachThis empirical study uses on‐line survey research methods with analysis of variance (ANOVA) statistical analysis.FindingsThe main findings of this study are: ASA minimizes noted limitations in peer assessment studies; publishing rates and years of service do not significantly influence quality assessment bias; ASA provides a comprehensive and fair assessment of journals; and ASA responds to established criteria as a new, independent system for journal ranking. This study also provides current rankings of educational administration and leadership journals.Research limitations/implicationsThis study points to the importance of continued research using ASA in journal assessment in education and other social sciences.Originality/valueThis study provides a new methodology in assessing journal quality, awareness, and importance to the field for journals in educational administration and leadership.
Negotiating and constructing an educationally relevant leadership programme
Authors: Giles David L. , Smith Richard J.M. 
Published: February 2012

PurposeThis article aims to discuss the conceptualisation process of developing a new one‐year taught‐master's programme in educational leadership at an Aotearoa/New Zealand university.Design/methodology/approachThe perspective taken is a highly personalised one from the two lead “drivers” of the programme and outlines the two‐year process of development of the programme from conception through to the first papers delivered in semester one 2008. The article describes the process, the concerns, the underlying philosophy, content and intended delivery pattern within the Master of Educational Leadership (MEdL) programme. As the programme designers, the authors wanted something discernibly different in orientation from the postgraduate programmes offered by other tertiary providers in Aotearoa/New Zealand. The content had to be both educationally and culturally relevant and reflect the nation's bi‐cultural heritage, yet growing multi‐ethnic population base.FindingsThe proposed programme was somewhat controversial and had a rather difficult journey through the New Zealand Vice Chancellors' Committee (NZVCC) that deals with the accreditation process. The philosophy of the programme centred on leadership rather than a management focus. Moreover, the philosophy was premised on both theory and practice as praxis and drew on both developmental and experiential models for leadership development.Originality/valueThis article leads a critical discourse amongst tertiary educators in educational leadership programmes towards a greater exploration and articulation of the critical, humanistic, and phenomenological nature of the programmes it offers.
User freedom or user control?
Authors: Freeman Stephanie 
Published: February 2012

PurposeThe purpose of this paper is to critically examine the often complex and contradictory argumentation of a spectrum of different Finnish public sector actors interviewed on the topical issue of Free/Libre Open Source (FLOSS) adoption.Design/methodology/approachThe science and technology‐inspired critical discourse‐analytical approach combines insights from Billig et al. and Fairclough, with a special focus on dilemmatic aspects of socially embedded discourses. The vocabularies used to justify FLOSS implementation highlight power struggles on the level of speech.FindingsThe identified dilemmatic discourses express the continuing tension between the freedom to choose, use and develop one's desktop in the spirit of FLOSS on the one hand, and the striving for better desktop control and maintenance by it staff and user advocates on the other.Research limitations/implicationsThe research acts as an opening for reframing common and axiomatic knowledge on FLOSS tools.Practical implicationsThe asymmetry between the layperson (the ordinary user) and the expert (IT staff) manifests itself in discourse in a way that calls for critical re‐evaluation of the language used in information communication technology (ICT) implementation and support. It also questions the role of pilots in ICT implementation.Originality/valueThe paper critically examines the often taken‐for‐granted ideals of open source software and elaborates a methodological tool for spotting power struggles on the level of speech.
The relationship between learning capability and organizational performance
Authors: Goh Swee C. , Elliott Catherine , Quon Tony K. 
Published: February 2012

PurposeThe purpose of this paper is to present a meta‐analysis of a subset of published empirical research papers that measure learning capability and link it to organizational performance. It also seeks to examine both financial and non‐financial performance.Design/methodology/approachIn a search of published research on learning capability and organizational performance, the authors identified 33 articles that met criteria for inclusion in the meta‐analysis. Both objective and perceptual measures of organizational performance were considered to be acceptable. The data were analyzed using the Hunter and Schmidt meta‐analysis software.FindingsThe findings support a positive relationship between learning capability and organizational performance, with stronger results for non‐financial than financial performance. This has significant implications for justifying the investment in building a learning capability in organizations. Recommendations for managers are provided, such as the use of learning capability measures and the need to measure performance.Research limitations/implicationsThe paper discusses the implications of these results for further theory building and development to advance knowledge in the field. This includes addressing the need for new research designs, the issue of causality, potential mediating effects and the impact of context in better understanding this complex relationship. It suggests that research is also needed to increase our understanding of how to effectively build this learning capability.Originality/valueThis meta‐analysis provides empirical evidence to support the value of building a learning capability in organizations.
Managing for continuous improvement in off‐site construction
Authors: Meiling John , Backlund Fredrik , Johnsson Helena 
Published: February 2012

PurposeSeveral off‐site manufacturing companies in Sweden have attempted to apply lean management to improve process effectiveness and efficiency. A state of continuous improvement is a key goal of lean management, as described in, e.g. Likers 4P model. The aim of this study is to test a method to measure the degree to which lean management principles have been adopted by companies that base their production on off‐site manufacturing, as a prerequisite for a sustainable approach to continuous improvement.Design/methodology/approachA survey is applied as research method, using a questionnaire based on the authors' perceptions of best practices corresponding to each lean management principle. Two questionnaires were distributed to both management and factory production personnel in two off‐site manufacturing firms in Sweden.FindingsThe Likert scores regarding the degree to which lean principles have been applied in the two studied companies showed similar patterns (and similar differences between the management and production personnel's responses), indicating that the results can be generalised within an off‐site construction context. The study shows that continuous improvements must emerge and evolve simultaneously with a focus on processes, people and long‐term thinking.Research limitations/implicationsIn order to obtain more generalised and detailed results a more extensive survey covering several companies, as well as more detailed case studies and more questions regarding each principle, are needed. A multivariate analysis will also scan the material for further dependences.Originality/valueThe paper highlights several aspects that are important for management to be aware of when aiming for continuous improvements in off‐site manufacturing.
Divide and prosper? When partitioned prices make sense
Authors: Love Edwin 
Published: February 2012

PurposeThis research seeks to investigate the relationship between product bundling strategies and brand value.Design/methodology/approachThree studies were conducted, two using student subject pools and another using data collected from online auctions. The impacts of brand and bundling strategy stimuli on the dependent variables product choice and price paid were measured.FindingsBundles offered by low‐tier brands are more attractive when they are offered in a combined price format than in a partitioned price format. Bundles offered by high‐tier brands are more attractive when they are offered in a partitioned price format than in a combined price format.Research limitations/implicationsThe cost of bundle elements to the firm, which may influence consumer reference prices, is not considered in this research. Also, the impacts of bundle pricing strategies are evaluated on the bundles only; the influence of a given strategy on a product portfolio is left for future research.Practical implicationsFirms should consider the status of its brand within its product category before deciding on a bundle pricing strategy.Originality/valueThis research has important implications regarding the pricing of product bundles. It also provides a new perspective on how consumers evaluate product bundles
Consumption hedging and home‐country bias in a model of international capital market equilibrium
Authors: Schnabel Jacques A. 
Published: February 2012

PurposeThe purpose of this paper is to develop a model of international capital market equilibrium where investors exhibit home‐country bias due to their desire to hedge real consumption.Design/methodology/approachThis paper posits a two‐stage process of portfolio choice for the representative investor of a country. In the first step, the investor's benchmark portfolio is determined, whereas in the second step, his optimal portfolio is chosen. The latter portfolio maximizes the expected portfolio rate of return minus the risk tolerance weighted variance of tracking error. The market equilibrium implications of the portfolio optimality conditions are determine via aggregation across all investors and countries.FindingsA revised security market line is derived that differs from the traditional security market line in terms of vertical intercept, slope, and beta coefficient. It is demonstrated that the derived model may be interpreted as a multi‐country generalization of the Chen‐Boness extension of the capital asset pricing model under uncertain inflation.Originality/valueThis paper presents an innovative application of Roll's tracking portfolio paradigm. Another novel feature is the derivation of the international capital market equilibrium implications of such portfolio choice behaviour.
Bank concentration and financial constraints on firm investment in UK
Authors: Abubakr Saeed , Esposito Franco 
Published: February 2012

PurposeThe purpose of this paper is to investigate the impact of bank concentration on firm financial constraints to perform investment across two types of financial constraints firms.Design/methodology/approachThe authors analyse this relationship by estimating the investment‐cash flow sensitivity across groups of firms classified according to debt maturity structure model. The firms were classified as short‐term and long‐term debt dependent firms. Empirically the authors analyze a sample that consists of the most recent dataset (over 2001‐2009) of UK firms that engage in foreign direct investment by using fixed‐effects and GMM‐IV estimation techniques.FindingsBank concentration was found to relax financial constraints on firm level investment. Results indicate that higher level financial constraints are associated with short‐term debt dependent firms that exhibit high level of investment‐cash flow sensitivity. Further, it was found that bank concentration is associated with reduction in financial constraints on firm investment and this effect is stronger for short‐term debt dependent firms.Originality/valueUnlike previous studies, the paper investigates the bank concentration effects on UK foreign direct investing firms that are uniquely classified; based on distinctive dimension of financial frictions in capital market. Estimated results ascertain that information‐based hypothesis is pertinent to the UK capital market.
On the cross‐methodological validation of bank efficiency assessments
Authors: Perera Shrimal , Skully Michael 
Published: February 2012

PurposeSince there is no agreement on the consistency of their estimates, the purpose of this paper is to investigate whether parametric stochastic frontier analysis (SFA) and nonparametric data envelopment analysis (DEA) generate consistent bank efficiency assessments.Design/methodology/approachThe authors utilize four alternative efficiency computation models: two DEA technical efficiency models based on constant and variable returns to scale, and two SFA cost efficiency models employing Translog and Fourier functional specifications. An unbalanced panel of 59 Indian banks over 1990‐2007 is employed as a model, developing country, banking market.FindingsThe Translog and Fourier specifications in SFA and the constant and variable returns to scale assumptions in DEA are found to rank and identify “best‐practice” and “worst‐practice” approximately in the same order. The association between DEA efficiency estimates and non‐frontier standard performance measures, however, is mixed and inconclusive. Unlike DEA scores, SFA efficiency assessments were found to be consistent with cost and profit ratios and hence are “believable”.Practical implicationsFor regulators and bankers alike, the authors' findings highlight the importance of investigating the consistency of efficiency scores across various research methods. They should ensure that frontier‐based efficiency assessments are not simply “artificial constructs” of models' assumptions/specifications.Originality/valueThis paper extends the existing literature by checking jointly the statistical consistency of both DEA technical efficiency scores and SFA cost efficiency scores. The prior studies focus either on technical efficiency or cost efficiency, but not both. Moreover, as far as the authors are aware, this is the first cross‐methodological validation study to focus on bank efficiency in the context of a developing country banking market.
