Fourier series based finite element analysis of tube hydroforming
Authors: Guan Yabo , Pourboghrat Farhang , Yu Woong‐Ryeol 
Published: September 2006

PurposeThe purpose of this paper is to provide an axisymmetric model of tube hydroforming using a Fourier Series based finite element method.Design/methodology/approachFourier series interpolation function, which considerably reduces the size of the global stiffness matrix and the number of variables, is employed to approximate displacements. The material of the tube is assumed to be elastic‐plastic and to satisfy the plasticity model that takes into account the rate independent work hardening and normal anisotropy. Numerical solution obtained from an updated Lagrangian formulation of the general shell theory is employed. The axial displacement stroke (a.k.a. axial feed) during tube hydroforming is incorporated using Lagrange multipliers. Contact constraints and boundary friction condition are introduced into the formulation based on the penalty function, which imposes the constraints directly into the tangent stiffness matrix. A forming limit curve based on shear instability and experimental measurements are used as fracture criteria.FindingsThe results obtained from this new formulation are compared against the nonlinear finite element code ABAQUS and experimental measurements for isotropic and transversely anisotropic tube materials. The hoop and axial strains predicted with AXHD code compared excellently with those from ABAQUS FEM code using plane stress axisymmetric (SAX1) and four‐node shell (S4R) elements. However, in the case of aluminum, the numerically predicted maximum hoop strain underestimated the actual hoop strain measured from the tube bulging experiment.Practical implicationsThe axisymmetric hydroforming program (AXHD) developed in this work is very efficient in simulating the free‐forming stage of the tube hydroforming process under simultaneous action of internal pressurization and displacement stroke.Originality/valueAlthough Fourier Series based finite element method has been used in metal forming, the extended application presented in this paper is novel in the finite element analysis of tube hydroforming.
A logit analysis of electronic banking in New Zealand
Authors: Gan Christopher , Clemes Mike , Limsombunchai Visit , Weng Amy 
Published: September 2006

PurposeIn this paper the competitive landscape of financial institutions is shifting and internet banking is no longer a competitive advantage but a competitive necessity for banks. However, a limited number of empirical studies have been published in the marketing literature about electronic banking. This paper seeks to examine consumers' choices between electronic banking and non‐electronic banking in New Zealand.Design/methodology/approachThe paper shows that the data for this analysis were obtained through a mail survey sent to 1,960 households in New Zealand. The decision to use electronic banking is hypothesised to be a function of service quality dimensions, perceived risk factors, user input factors, price factors, service product characteristics, individual factors and demographic variables such as age, gender, marital status, income, etc. Logistic regression is used to analyse the data. The discrete dependent variable measures whether an individual is an electronic banking or non‐electronic banking user.FindingsThe findings in the paper show that the output from the logistic regression indicates that the service quality, perceived risk factors, user input factors, employment, and education are the dominant variables that influence consumers' choice of electronic banking and non‐electronic banking channels.Practical implicationsThis paper provides an improved understanding of consumers' choice between electronic and non‐electronic banking. This paper also identifies new relationships, and provides findings that further support, confirm, or contradict previous studies. In addition, it provides insights into the links between electronic banking and consumer decision making, to help provide strategies, recommendations and guidelines for the banking industry.Originality/valueThe paper shows how banks are developing, and utilizing new alternative distribution channels to reach their customers.
An approach to profit‐maximizing product design on the basis of the platform concept
Authors: Riesenbeck Hajo , Herrmann Andreas , Heitman Mark , Algesheimer René 
Published: September 2006

PurposeThe purpose of this paper is to show that conjoint measurement has proved to be an effective tool for identifying customer preferences. However, in order to market products and services successfully information about the variable costs for the various attributes and their respective levels needs to be considered. A platform approach could reduce these costs and generate very effective preference drivers.Design/methodology/approachThis paper proposes and elaborates a model, which examines a joint implementation of conjoint measurement and the platform concept. The model is empirically tested on data gathered on a stratified random sample of customers through the application of valid and reliable measures. The model is tested using a conjoint and regression design.FindingsThe results in this paper show the usefulness of a joint implementation of conjoint measurement and the platform concept. Variable costs can be reduced considerably and preferences can be adequately identified. In combining market information (preference data) with cost data profitability is increased.Originality/valueThis paper specifically is to address the following four questions: What are the most important attributes and levels for customers? What are the variable costs for those attributes and levels? Could an implementation of the platform concept reduce those costs significantly? Are there any efficient preference drivers?
Reliability considerations in the design of cellular manufacturing systems
Authors: Das K. , Lashkari R.S. , Sengupta S. 
Published: September 2006

PurposeThe purpose of this paper is to: develop an effective cellular manufacturing system (CMS) design methodology by simultaneously considering system costs and individual machine reliabilities; and propose a combinatorial search‐based solution procedure to solve large‐sized problems.Design/methodology/approachThis paper presents a multi‐objective mixed integer‐programming model for the design of CMS with the objective of minimizing costs and maximizing system reliability. The approach optimizes inter‐cell material handling costs, the variable cost of machining operations, and the machine under‐utilization costs. It also maximizes the system reliability by selecting process routes for the part types with the highest system reliability for the machines along the routes. To solve the multi‐objective, multiple process plan model, a simulated annealing (SA)‐based algorithm is developed. The algorithm follows the basic steps of SA, but also incorporates the genetic algorithm (GA) operations of crossover and mutations to generate better neighboring solutions from the current good solutions.FindingsThe algorithm in the paper solves the multi‐objective CMS design model and generates near optimal solutions for medium to large‐sized problems within reasonable limits of CPU time.Practical implicationsIn the paper the CMS design approach can be implemented to improve reliability performance of the CMS.Originality/valueA new CMS design methodology in this paper, which minimizes system costs and maximizes machine‐related system reliability, is developed. The proposed algorithm, which combines the basic steps of SA and crossover and mutation operations of GA, will enable CMS designers and users to obtain near optimal solutions for practical‐sized problems within reasonable time limits.
Assessing quality relationships in public housing
Authors: Chan Albert P.C. , Wong Francis K.W. , Lam Patrick T.I. 
Published: September 2006

PurposeQuality management in construction has received increasing attention in recent years. Numerous studies have been carried out which have highlighted the factors affecting quality of construction. Each study has contributed to identifying factors affecting quality. However, there is little published work that comprehensively addresses the factors specifically affecting the quality of Hong Kong public housing, which has long been criticized as having poor quality performance. This paper aims to identify the factors affecting the quality outcomes of public housing projects.Design/methodology/approachPotential quality attributes affecting quality performance was identified from the literature. A five‐page questionnaire was then developed to determine how these identified factors affect the quality scores of public housing projects. Factor analysis and multiple regression analysis were used to examine the data obtained from the questionnaire survey.FindingsAnalysis of 54 cases indicated that the project manager's experience in running public housing projects was the most important factor affecting the quality scores. Other important factors include a proactive quality culture; the extent of using direct skilled labour; a comprehensive subcontract inspection system; the competency of site labour, and the client's emphasis on quality, safety and environment.Research limitations/implicationsThe empirical results were based locally in Hong Kong, however, the lessons learnt are generally applicable. For future research the methodology adopted can be replicated elsewhere to facilitate international comparison of quality practices.Originality/valueA predictive model for quality performance has been developed. The findings can assist project managers to better manage public housing projects and achieve higher quality performance.
Empirical investigation of the hard and soft criteria of TQM in ISO 9001 certified small and medium‐sized enterprises
Authors: Lewis Winston G. , Fai Pun Kit , Lalla Terrence R.M. 
Published: September 2006

PurposeThis paper presents the main findings of an empirical study that investigates the effects of the “soft” and “hard” criteria of total quality management (TQM) in four ISO 9001 certified small and medium‐sized enterprises (SME) in Trinidad and Tobago (T&T).Design/methodology/approachThe study adopted an ethnographic research approach, and used the analytic hierarchy process (AHP) to determine the extent to which these criteria were implemented at the point of ISO 9001 certification. By complementing the literature review, a hierarchy framework of TQM implementation via ISO 9001 was developed. The framework comprised three levels of criteria, sub‐criteria and elements which determine the effectiveness of TQM implementation in SME. Inputs from 16 evaluators including senior executives and representatives from the studied companies were invited. The combined opinions from evaluators were used to identify and prioritize these criteria and components.FindingsThe results showed that the “soft” criteria were implemented less than the “hard” criteria in SME. The AHP findings supplement the body of knowledge existing in compliance requirements of ISO 9001 and provide insights on how SME perceive the importance of “soft” versus “hard” criteria in TQM implementation. These findings highlight the need to align SMEs' prevailing quality culture with top management and considers it as one of the focal compliance requirements for future revisions of the ISO 9001:2000 Standard.Research limitations/implicationsBecause of the ethnographic nature of the study, it was possible to obtain data from only four SME.Practical implicationsSME in T&T may apply the findings of the empirical research to design, implement and continually improve their quality management systemOriginality/valueThis paper makes a contribution to the body of knowledge in the field of quality management in a region where such work is limited. It adds value by empirically measures TQM implementation by determining the extent to which its criteria is implemented in ISO 9001 certified SME.

Authors: Barber Kevin D. , Eduardo Munive‐Hernandez J. , Keane John P. 
Published: September 2006

PurposeThis paper presents a practical methodology for developing a process‐based knowledge management system (KMS) for supporting continuous improvement (CI) and asset management.Design/methodology/approachAn action research methodology was used to develop a KMS to support CI in a manufacturing company. The KMS is evaluated through application in the case study company. This methodology ensures a consistent approach to carrying out all improvement initiatives. The final part of the methodology addresses the construction of an intranet‐based knowledge warehouse. This contains several searchable areas such as existing information on assets, new knowledge generated from projects, details of expertise in the business and links to the key business drivers through the corporate intranet.FindingsThe KMS is shown to support CI initiatives through the utilization of available data already held within the company's management databases (production, quality and maintenance) including consideration of corporate strategic plans. Process models trigger the application of improvement tools and projects in a true CI environment.Research limitations/implicationsThis methodology acknowledges both tacit and explicit knowledge within the company, and it represents an appropriate environment to promote and develop a true learning organization.Practical implicationsThe system developed is shown to be flexible and has been implemented in a manufacturing environment. Financial benefits are presented.Originality/valueThe approach used is novel and integrates several areas of IT and process improvement techniques. The resulting methodology is applicable to large and small companies without requiring major IT support facilities. The methodology supports the development of true learning organizations.
“Mum effect”: principals' reluctance to submit negative feedback
Authors: Yariv Eliezer 
Published: September 2006

PurposeSubmitting negative feedback is a stressful experience which both superiors and subordinates try to avoid. Do principals adapt to the mum effect and hide their (negative) thoughts and feelings, or do they confirm Weeninget al.hypothesis about the existence of facilitating conditions.Design/methodology/approachAbout 40 elementary school principals described in semi‐structured interviews cases of poor performing teachers whom they had to inform about their shortcomings.FindingsFour consecutive stages, which escalated in directedness and criticism were found. Each stage depended on the outcomes of the previous one. Initially, half of the principals preferred first to ignore, but later 88 percent held a soft negative feedback and problem‐solving oriented discussions. When these discussions did not bring the expected results, about 80 percent criticized the worker orally. Only 30 percent criticized in writing. That process was accompanied with mixed feelings, mainly those of anger and compassion.Research limitations/implicationsThe results emphasize the need for individual guidance as how to overcome their hesitattions and give effective feedback to their poor‐performing teachers. As an exploraty study, its major weakness was the reliance on one side of the equation – the principals.Originality/valueMost earlier studies on mum effect were conducted in experimental setting. This study provides a uniquely realistic evidence of the interpersonal processes within the workplace. The worker appraisal and the transmission of (negative) feedback are explored through emotional lens.
Fear in organizations
Authors: Zoghbi Manrique de Lara Pablo 
Published: September 2006

PurposeThis study examines the relationship between interactional justice, which is a specific type of organizational justice perception that reflects how a person is treated by an authority, and workplace internet deviance (or Cyberloafing) as a category of deviant workplace behavior. The tested model suggests that interactional justice affects cyberloafing by influencing fear of formal punishment –as an intimidation construct– which, in turn, prompts employees to reciprocate with deviant workplace internet behaviors.Design/methodology/approachData were collected from 147 (19.4 percent) of the 758 non‐teaching staff at a Spanish public university. Accessibility of individual e‐mail accounts was similar for all employees. E‐mails asking for collaboration were sent in two phases. A questionnaire was posted on the university Intranet and could be accessed by clicking on a link in the e‐mails.FindingsStructural equation modeling results support that interactional justice is an antecedent of fear of formal punishment that fully mediates the relationship between interactional justice and workplace internet deviance.Research limitations/implicationsThe researched employees have job conditions inherent to the peculiarities of the public sector which may limit the ability to extrapolate the findings in the private sector. The fear construct was assessed by a self‐supplied scale, and thus the presence of shades of other similar emotions could not be discounted. Findings provide a more understandable mechanism of the influence of supervisor disrespect on cyberloafing.Practical implicationsThese findings contribute to an understanding of the ways in which organizations can control cyberloafing and provide reservations about the intimidator strategy efficiency.Originality/valueThe use of fear of punishment as a mediator on this link is unprecedented.

Authors: Hass Susan , Abdolmohammadi Mohammad J. , Burnaby Priscilla 
Published: September 2006

PurposeBy conducting the 2006 global Common Body of Knowledge (CBOK) study, The Institute of Internal Auditors (The IIA) attempts to better understand the expanding scope of internal auditing practice throughout the world. The purpose of this review of recent internal auditing literature in The Americas is to document how the internal audit function is changing in response to the shifts in global business practices.Design/methodology/approachThe literature in The Americas is reviewed with a focus on developments that have implications for the expanded scope of internal auditing and the changing skill sets of internal auditors. This focus has implications for CBOK 2006.FindingsThe literature indicates a paradigm shift in the activities performed by internal auditors. The increasing complexity of business transactions, a more dynamic regulatory environment in the USA, and significant advances in information technology have resulted in opportunities and challenges for internal auditors. Although in 2004, The IIA responded to the changing organizational environment by updating the professional practices framework, more work needs to be done to prepare internal auditors for the expanded set of skills and knowledge required to perform audits of the future.Originality/valueBy presenting an overview of past literature in The Americas and discussing the shifting demands on internal audit services, the researchers hope to motivate further research in the field.

Published: September 2006

PurposeTo present the results of a survey of internal auditors worldwide to determine the scope of the topics to be included in The IIA's Global Common Body of Knowledge Study (CBOK) 2006.Design/methodology/approachThe researchers developed a prescope questionnaire and surveyed a small sample of experienced internal auditors worldwide. All three CBOK 2006 teams (Americas, Asia Pacific and Europe/Africa) participated in data gathering from internal auditors in their regions. The questionnaire contained topics that were adapted from The IIA Practice Standards, past CBOKs ands other relevant prior research. The questionnaire also provided space for inclusion of “Other” topics by respondents.FindingsThe respondents agreed with the inclusion of a majority of the topics listed in the prescope questionnaire in the global CBOK 2006 survey. Many “Other” topical areas were also suggested for inclusion.Originality/valueThe survey results are providing invaluable information to the researchers in their efforts to develop the questionnaire for global CBOK 2006.
Internal auditors: their role in the institutions of higher education in Malaysia
Authors: Zakaria Zamzulaila , Devi Selvaraj Susela , Zakaria Zarina 
Published: September 2006

PurposeTo provide evidence on the establishment of the internal audit function in the higher education institutions in Malaysia and also to obtain the perceptions of the management of the higher education institutions towards the role and scope of the internal audit.Design/methodology/approachSample consisted of 17 public universities and 49 private universities in Malaysia and variables used by Gordon and Fischer were adopted for this study.FindingsThe findings revealed that a substantial number of private institutions of higher education do not have an internal audit function. The study also indicates that the management of both types of institutions have similar perceptions on the role of internal auditors and the important audit areas as there are no significant differences between public and private institutions of higher education.Research limitations/implicationsThe main limitation of this study is that it only examines whether the scope of internal audit covers the areas mentioned by treasury circular or the IIA Guideline. It ignored the extent to which the higher education institutions comply with both guidelines. It is, therefore, suggested that future research could consider the degree of compliance to the above guidelines. The difference in the role of internal auditing between the education sector and other industries represents an interesting area for further research. Also, since this study only focuses on the perceptions of the management and the internal auditor themselves, the perception of other parties such as regulators and the audit committee on the role of internal audit in institutions of higher education will be an interesting area to explore for future research.Practical implicationsThe failure to establish an internal audit function in the private universities calls for government intervention to ensure the existence of an internal audit function in the private sector higher education institutions.Originality/valueThe findings of this paper will be important in further refining the scope of the internal audit function in the higher educations institutions in Malaysia, especially to policymakers concerned with regulations governing the internal audit function.
