Effect of viscous dissipation on mixed convection flow of water near its density maximum in a rectangular enclosure with isothermal wall
Authors: Hossain Anwar , Subba Reddy Gorla Rama 
Published: June 2006

PurposeTo investigate the effect of viscous dissipation on unsteady, combined convective heat transfer to water near its density maximum in a rectangular cavity.Design/methodology/approachThe upwind finite difference scheme along with successive over relaxation iteration technique is used to solve the governing equations for mixed convection flow of water with density maximum inversion in a rectangular cavity.FindingsThe effect of viscous dissipation was to increase the fluid temperature and resulted in the formation of vortex motion near the lower part of the cavity in an opposite direction to the central vortex. An increase in the Eckert number and Reynolds number of the flow resulted in augmented surface heat transfer rates from the top heated surface.Research limitations/implicationThe analysis is valid for unsteady, two dimensional laminar flow. Isothermal conditions are assumed for the top and bottom walls. An extension to unsteady three dimensional flow case is left for future work.Practical implicationsThe method is very useful to analyze nuclear reactor thermal/hydraulic loss of coolant transients, energy conservation, ventilation of rooms, solar energy collection, cooling of electronic equipment, dispersion of waste heat in estuaries and crystal growth in liquids.Originality/valueThe results of this study may be of interest to engineers interested in heat transfer augmentation of mixed convection in window cavities.
A new algorithm for moving boundary problems subject to periodic boundary conditions
Authors: Ahmed S.G. 
Published: June 2006

PurposeThe paper aims to introduce a new algorithm based on the boundary integral method developed to solve moving boundary phase change problem subject to all possible cases of cyclic boundary temperature.Design/methodology/approachIn the present paper, the phase change problem with periodic boundary temperature, which may be above or below the phase change temperature, is analyzed. The analysis is based on applying the boundary integral method in a new numerical algorithm. There are two main topics of the analysis herein. The first one is to study the direct effect of the cyclic boundary temperature on the movement of the moving boundary for various Stefan numbers. The second one is check that the proposed method covers all possible cases of cyclic boundary temperature with respect to the phase change temperature.FindingsWhen using the proposed method, it is found an easy mathematical manipulation and the results can be improved when fine time step size used.Originality/valueThe proposed method is a very new method, which can be applied to any case of moving boundary phase change problem subject to any case of cyclic boundary temperature. Also the proposed method takes into consideration different parameters that affect directly on the evolution of the moving boundary such as Stefan number, etc.
Isoparametric finite element approximation for a boundary flux problem
Authors: Andreev Andrey B. , Todorov Todor D. 
Published: June 2006

PurposeTo study and to analyze a second order finite‐element boundary‐flux approximation using isoparametric numerical integration.Design/methodology/approachThe numerical finite‐element integration is the main method used in this research. Since a domain with curved boundary is considered we apply an isoparametric approach. The lumped flux formulation is another method of approach in this paper.FindingsThis research study presents a careful analysis of the combined effect of the numerical integration and isoparametric FEM on the boundary‐flux error. Some L2‐norm estimates are proved for the approximate solutions of the problem under consideration.Research limitations/implicationsThe authors offer a general study within the framework of the boundary‐flux approximation theory, which completes the results of published works in this scientific field of research.Practical implicationsA useful application is to employ appropriate quadrature formulae without violating the precision of the boundary‐flux FEM. The lumped mass approximation is also an important practical approach to the problem in question.Originality/valueThe paper presents an entire investigation in FE boundary‐flux approximation theory, in particular, elements of arbitrary degree and domains with curved boundaries. The work is addressed to the possible related fields of interest of postgraduate students and specialists in fluid mechanics and numerical analysis.
Barriers women face in information technology careers
Authors: Michie Susan , Nelson Debra L. 
Published: June 2006

PurposeThe purpose of this study was to determine if perceptions that women and men hold toward careers in information technology (IT) and toward women working in IT create potential barriers that may prevent women managers from pursuing careers in IT.Design/methodology/approachA field study was designed to test the hypotheses. The subjects were graduate students pursuing either an MBA or IT management degree.FindingsThe results revealed that males had greater self‐efficacy for IT occupations, greater passion for computing, and less positive attitudes toward capabilities of women in IT. Our prediction that career barriers would intensify for women who chose an IT management option was not supported. These findings suggest that traditional work role expectations concerning women's efficacy for careers in IT still persist.Research limitations/implicationsThis research was limited by its focus on subjects in the early stages of a management career. To gain a better understanding of the barriers that women face in IT career fields, longitudinal studies are needed to track these barriers throughout the career development process.Practical implicationsIf organisations want to attract, retain, and advance women managers in IT fields, they must proactively address gender role biases and create work environments that build self‐efficacy expectations for women, as well as for men.Originality/valueMuch of the research on career barriers women face in IT is based on qualitative studies and anecdotal evidence. This study provides empirical evidence that barriers still exist for women in IT despite the enhanced demand for IT professionals and managers over the past decade.
Barriers to advancing female careers in the high‐tech sector: empirical evidence from Ireland
Authors: Cross Christine , Linehan Margaret 
Published: June 2006

PurposeThis paper sets out to examine the experiences of female managers in order to enhance our understanding of why there is a relative scarcity of senior female managers in one of the newest sectors of the Irish economy, the high‐tech sector. Because this sector has effectively only emerged in Ireland in the last 15 years, it had been expected to provide a unique genderless environment in which female managers would emerge in equal numbers to their male counterparts.Design/methodology/approachThis paper takes a qualitative approach. A series of interviews were carried out with 20 female junior and middle managers in this industry segment.FindingsThe results of the interviews illustrate that a combination of formal and informal organizational policies and procedures, together with a “self‐imposed” glass ceiling hamper women in junior and middle management positions from advancing to senior managerial roles in this important segment of the Irish economy.Research limitations/implicationsOne of the limitations of this study relates to the sample. Further research expanding on this initial sample into other industry sectors is required.Originality/valueOne issue that emerged from the interviews is the concept of a “self‐imposed glass ceiling”, where individual female managers are actively weighing up the costs and the benefits of moving to the next level of management. Based on their analysis of this information they are individually deciding whether or not to engage in the activities, which will assist their carrier progression. The role of individual choice may assist us in explaining the low numbers of women at senior management level.
Hilton highlights link between staff loyalty and e‐learning
Authors: Baldwin‐Evans Kay 
Published: June 2006

PurposeThe paper aims to examine an anonymous employee survey conducted by SkillSoft's client, Hilton International, in the summer of 2005.Design/methodology/approachThe paper presents the results of the annual survey, which is part of an ongoing program to establish how Hilton's online learning portal, Hilton University, is being used and to find out how employees are applying the learning at work. Another important reason for the survey is to discover whether there is indeed a link between development opportunities and staff loyalty and retention.FindingsThe paper demonstrates that 90 percent of respondents said they found Hilton University learning activities easily accessible, with almost three‐quarters of the opinion that learning opportunities specific to their needs could be located quickly. Around 85 percent ranked Hilton University as either good or very good and 90 percent of respondents were convinced that the resources they accessed through Hilton University helped them with their professional development. Some 74 percent agreed that management supported them through the learning process. From a management perspective, 64 percent of managers found it straightforward to monitor and support the learning process of individuals in their teams. Around 95 percent of respondents said they appreciated the opportunity Hilton was giving them to develop their knowledge. This figure gives credence to the theory that training benefits company‐employee relations: 98 percent went on to say that they would recommend Hilton University to colleagues.Practical implicationsThe paper backs the view that continuous professional development is an important factor in staff retention.Originality/valueThe paper reports that 37 percent of respondents said that being offered development opportunities was “the most important” factor in them deciding to continue their career with Hilton. An additional 50 percent said that although it was not “the” factor, being given the opportunity to develop professionally was very important to them.

Authors: Thakkar Jitesh , Deshmukh S.G. , Shastree Anil 
Published: June 2006

PurposeTo explore the potential for adoption of TQM in self‐financed technical institutions in the light of new demands and challenges posed by customers/students and society.Design/methodology/approachThe paper presents use of quality function deployment (QFD) which prioritizes technical requirements and correlates them with various customers'/students' requirements for the present Indian context. As an extension to the basic model of QFD – house of quality (HOQ), the scope for futuristic improvements is explored through a four‐phased QFD process. Challenges involved in the implementation of TQM are investigated using an approach of force field analysis.FindingsIdentifies technical and students' requirements for the modern educational set‐up. Provides information about the severity of various technical requirements of competitive education. Recognizes the need for continuous improvement, cultural change and effective use of financial resources to improve the value addition at each level. Develops an understanding of the issues to be addressed at each phase of TQM implementation.Practical implicationsIt is expected that insights gained will help sensitize the emerging self‐financed institutions towards the demands of new age students. Conclusions derived will also provide some opportunities for reflection by students, faculty members and leaders/top management of institutions for continuous development at an individual as well as institutional level.Originality/valueA novelty of work lies in the use of a mix of qualitative and quantitative approaches, which not only evaluates the present system but develops an understanding of future challenges to continuous improvement.
Information security: management's effect on culture and policy
Authors: Knapp Kenneth J. , Marshall Thomas E. , Kelly Rainer R. , Nelson Ford F. 
Published: June 2006

PurposeThis study proposes to put forward and test a theoretical model that demonstrates the influence of top management support on an organization's security culture and level of security policy enforcement.Design/methodology/approachThe project used a combination of qualitative and quantitative techniques. The grounded theory approach was used to analyze responses to open‐ended questions answered by 220 certified information system security professionals. Using these responses, a survey instrument was developed. Survey results were analyzed using structural equation modeling.FindingsEvidence suggests that top management support is a significant predictor of an organization's security culture and level of policy enforcement.Research limitations/implicationsDuring instrument validation, a special effort removed survey items that appeared overly intrusive to the respondents. In this endeavor, an expert panel of security practitioners evaluated all candidate items on a willingness‐to‐answer scale. While especially helpful in security, this scale may be used in other research domains.Practical implicationsPractitioners should understand the impact of top management support on achieving security effectiveness. Based on the findings of this study, low levels of executive support will produce an organizational culture less tolerant of good security practices. Low levels of support will diminish the level of enforcement of existing security policies.Originality/valueResearchers developed original scales to measure levels of top management support, policy enforcement, and organizational culture. The scales demonstrated acceptable reliability and validity scores.

Published: June 2006

PurposeAims to review the key concepts of competency management (CM) and to propose method for developing competency method.Design/methodology/approachExamines the CM features of 22 CM systems and 18 learning management systems.FindingsFinds that the areas of open standard (XML, web services, RDF), semantic technologies (ontologies and the semantic web) and portals with self‐service technologies are going to play a significant part in the evolution of CM systems.Originality/valueEmphasizes the beneficial attributes of CM for private and public organizations.
Human resource development in construction organisations
Authors: Raidén Ani B. , Dainty Andrew R.J. 
Published: June 2006

PurposeThe concept of the learning organisation (LO) is associated with an advanced approach to human resource development (HRD) characterised by an ethos of self‐responsibility and self‐development. The learning climate that this engenders is supported by temporary organisational structures responsive to environmental change. The purpose of his paper is to present case study research of the HRD strategy, policy and practice of a large UK‐based construction contractor in relation to the concept of LO.Design/methodology/approachEmpirical data for the examination of the “chaordic” LO were drawn from recent doctoral research that investigated a large UK‐based construction contractor's strategic human resource management practices.FindingsThe analysis suggests that the organisational project‐based structure and informal culture combine to form a “chaordic LO”. A “chaordic enterprise” comprises a complex organisation that operates in a non‐linear dynamic environment. However, it appears that this approach has evolved unintentionally rather than as a result of targeted strategic human resource management (SHRM) policies, which in turn reflects a genuine commitment to advanced HRD.Originality/valueThe findings render previous assertions that the industry fails to invest in its employees highly questionable. They suggest a need for further research to reveal how such approaches can be captured in replicate in the future.
An examination of educational institutions' knowledge performance
Authors: Kumar Naresh , Idris Khairuddin 
Published: June 2006

PurposeThis study aims to explore the relationships between learning organisation dimensions, institutional characteristics and knowledge performance among Malaysian private higher learning institutions.Design/methodology/approachThe researchers sought managers' responses to the dimensions of the learning organisation questionnaire (DLOQ) together with perceived measures of private higher learning institutions' knowledge performance to determine relationships.FindingsIt was discovered that there were positive, medium to high, and significant relationships between the seven dimensions of the learning organisation and the dependent variable, perceived knowledge performance. The three dimensions that demonstrated strong relationships were team learning, embedded systems and provision of leadership. The institutional characteristics that jointly affect the private higher learning institutions' performance were perceived level of institutional commitment to institutional/professional service and institutional level of commitment to effective teaching and learning.Originality/valueOn the whole, the findings of this study provide empirical information, which supports the concept of the learning organisation and their positive influence on the knowledge performance, especially in the private higher education industry. Implications for research and practice as well as recommendations for future studies were highlighted to facilitate those who were involved in learning research.
The impact of a design management training initiative on project performance
Authors: Bibby L. , Austin S. , Bouchlaghem D. 
Published: June 2006

PurposeOver recent years there has been a significant drive away from traditional procurement routes where contractors find themselves with an increasing responsibility for the control of the design – a process they have had little experience in managing. Yet this is an area of significant opportunity for those contractors who can adapt quickly and effectively to the changing construction market. However, many current processes are insufficient to manage today's demanding and fast‐moving projects. This paper aims to address this issueDesign/methodology/approachThe paper reflects on the deployment of a design management training initiative to improve performance in a major UK civil and building design and construction company. It investigates the impact of the training initiative, critical practices and a suite of 25 tools on design management performance across the company. The methodology included a structured questionnaire, design management maturity assessment, semi‐structured interviews and a case study.FindingsThe paper highlights benefits delivered by the initiative as well as the practices and tools crucial to successful design management. A range of implementation barriers that affect the success of design management practices is also highlighted together with strategies used on a design and build project to overcome them.Originality/valueThe paper should be helpful to those involved in design management and the development of tools and practices to improve the performance of companies and project teams.
A novel multiple linear regression model for forecasting S‐curves
Authors: Blyth Karl , Kaka Ammar 
Published: June 2006

PurposeCash flow forecasting is an indispensable tool for construction companies, and is essential for the survival of any contractor at all stages of the work. A simple and fast technique of forecasting cash flow accurately is required, considering the short time available and the associated cost. Seeks to examine this issue.Design/methodology/approachThe paper argues that instead of producing an S‐curve that is based on historical projects combined (state‐of‐the‐art is based on classifying projects into groups and producing a standard curve for each group simply by fitting one curve into the historical data), here the attempt is to produce an individual S‐curve for an individual project. A sample of data from 50 projects was collected and 20 criteria were identified to classify these projects. Using the most influential criteria, a multiple linear regression model was created to forecast the programme of works and hence the S‐curves. A further six projects were used to validate and test the model.FindingsThe results of the model developed in this paper were compared with previous models and evaluated. It is concluded that the model produced more accurate results than existing value and cost models.Originality/valueThe paper proposes an alternative and novel approach to the development of standard value and cost commitment S‐curves. This approach is based on a multiple linear regression model of the programmes of works.
Internet advertising strategy alignment
Authors: Boudreau Marie‐Claude , Watson Richard T. 
Published: June 2006

PurposeBecause the web can be an influential medium for attracting and retaining customers, it is critical to examine the connection between web advertising and corporate strategy. This is particularly true for multinational organizations, which face the most complex organizational environment. The purpose of this paper is to propose that multinational organizations should be concerned with alignment of their strategy and web image because of the size and geographic spread of their operations.Design/methodology/approachThis research paper reviews the fundamental global strategies that corporations can pursue (e.g. integration, transnational, national responsiveness) and then empirically examine the relationship between corporate global strategy and web advertising strategy for 20 multinational organizations.FindingsThe results show that misalignment between corporate global strategy and web advertising strategy is reasonably common. For two thirds of the companies in our sample, there was imperfect alignment.Originality/valueThe paper suggests three reasons why this can be, and offer a tool that enables organizations to recognize how they should handle design and content matters for the combination of corporate and national web sites.

Authors: Moustakas Evangelos , Ranganathan C. , Duquenoy Penny 
Published: June 2006

PurposeThe purpose of this paper is to provide a conceptual overview of the process of unsolicited commercial e‐mail (UCE), propose a typology of UCE, and delineate key stakeholders of UCE, their roles and potential responses through a stakeholder analysis.Design/methodology/approachBased on the extant literature, this paper provides a conceptualization of the UCE process, delineating specific types of UCE. It uses stakeholder analysis to identify key members in the UCE process and the potential roles to be played by them in combating UCE.FindingsThis paper proposes a four‐way typology of the UCE process, identifies key stakeholders, and also mechanisms for tackling UCE.Research limitations/applicationsGiven the limited empirical research on this topic, this paper is exploratory in nature, integrating concepts from marketing and e‐commerce research streams. It will provide a solid conceptual foundation for future empirical research on UCE.Practical implicationsThis paper will be a useful resource for customers, Internet merchants, policy makers, direct marketing associations, agencies and consumer awareness groups that are working on Internet security, privacy and anti‐spam issues.Originality/valueThis paper addresses an important and timely issue, filling an important gap in current research on e‐mail marketing. It provides conceptual foundations on UCE, and deploys stakeholder analysis to suggest useful guidelines for practice.
