The effect of knowledge on system integration project performance
Authors: Hong Han‐Kuk , Kim Jae‐Sik , Kim Taehun , Leem Byung‐Hak 
Published: April 2008

PurposeThe paper aims to clarify the relationships between various components of knowledge possessed by the members of system integration (SI) project team and the project performance of those team members. From this lessons are learnt on SI project management issues and managerial implications regarding team member knowledge management for project performance are provided.Design/methodology/approachThe authors validated the model and tested the hypotheses using the structural equation model analysis LISREL.FindingsUsing data from 49 SI projects performed by a prominent consulting firm, the authors discovered a positive relationship between SI project team member knowledge and project performance. Notably, tacit knowledge was found to be influential, but explicit knowledge was not. The leadership capability of team leaders and the communication capability among team members were found to be important factors affecting project performance.Research limitations/implicationsA limited number of SI projects were analyzed due to difficulties with project selection and frequent movement of consultants during the data gathering process. As a result, additional analyses considering project size and complexity were not performed. Project team members' personal knowledge obtained through experience in similar projects or similar industries is very important to improve SI project performance. Leaders of participating SI projects have to think over project team members' tacit product knowledge and tacit process knowledge when building their project's team.Originality/valueThe main contribution of this paper lies in the establishment of a causal relationship between SI project team member knowledge and project performance, as well as in the proposed managerial implications for SI project knowledge management.
A qualitative re‐construction of project measurement criteria
Authors: Ojiako Udechukwu , Johansen Eric , Greenwood David 
Published: April 2008

PurposeFailure is encountered regularly within project‐based industries and there has been research for decades into this phenomenon. Much of it has considered the failure of projects in terms of the classic project progress issues such as time, cost and quality. Using cases from two major industries the authors aim to develop a different understanding of project measurement criteria. This work is part of a larger completed investigation into information systems and information technology (IS/IT) project management models, developed for industry comparisons.Design/methodology/approachDuring the study, the concept of project failure and success is investigated. The authors carry out a UK‐based, grounded study of two project‐based industries of differing maturity levels (construction and IS/IT) to investigate measures of project failure or success across the two industries.FindingsThe paper presents a reassessment of project measurement criteria. This is based on the separation of measures for project performance and project progress.Research limitations/implicationsThe adopted strategy of naturalistic inquiry has always been susceptible to the criticism that it relies too much on subjective interpretation of data. In addition, no clear relationship was established between the factors discussed and the criteria for measuring project success.Originality/valueThe paper discusses current differences in perception of what actually constitutes a failed or successful project. The paper highlights that often two different (but closely related) concepts, are being discussed by project stakeholders.

Authors: Prášil Ludvík , Mackerle Jaroslav 
Published: April 2008

PurposeThe finite element method (FEM) has become the prevalent technique used for analyzing physical phenomena in the field of structural, solid and fluid mechanics. The output of scientific papers is fast growing and professionals are no longer able to be fully up‐to‐date with all the relevant information. The purpose of this paper is to provide a bibliographical review on the application of FEM in mechanical engineering, specifically for the analyses and simulations of gears and gear drives from the theoretical as well as practical points of view.Design/methodology/approachThe following topics on gears and gear drives are handled from the computational points of view: gears in general, spur gears, helical gears, spiral bevel and hypoid gears, worm gears and other gear types and gear drives. The paper is organized into two parts. In the first one each topic is handled in a short text, relevant keywords are presented and current trends in applications of finite element techniques are briefly mentioned. The second part lists references of papers published for the period 1997‐2006.FindingsThis bibliography is intended to serve the needs of engineers and researchers as a comprehensive source of published papers on design, analysis and simulation of gears and gear drives.Originality/valueThe bibliography listed is by no means complete but it gives a comprehensive representation of different finite element applications on the subjects. It will save time for readers looking for information dealing with described subjects, not having an access to large databases or willingness to spend time with uncertain information retrieval.

Authors: Stein Erwin , Sagar Gautam 
Published: April 2008

PurposeThe purpose of this paper is to examine quadratic convergence of finite element analysis for hyperelastic material at finite strains via Abaqus‐UMAT as well as classification of the rates of convergence for iterative solutions in regular cases.Design/methodology/approachDifferent formulations for stiffness – Hessian form of the free energy functionals – are systematically given for getting the rate‐independent analytical tangent and the numerical tangent as well as rate‐dependent tangents using the objective Jaumann rate of Kirchoff stress tensor as used in Abaqus. The convergence rates for available element types in Abaqus are computed and compared for simple but significant nonlinear elastic problems, such as using the 8‐node linear brick (B‐bar) element – also with hybrid pressure formulation and with incompatible modes – further the 20‐node quadratic brick element with corresponding modifications as well as the 6‐node linear triangular prism element and 4‐node linear tetrahedral element with modifications.FindingsBy using the Jaumann rate of Kirchoff stress tensor for both, rate dependent and rate independent problems, quadratic or nearly quadratic convergence is achieved for most of the used elements using Abaqus‐UMAT interface. But in case of using rate independent analytical tangent for rate independent problems, even convergence at all is not assured for all elements and the considered problems.Originality/valueFirst time the convergence properties of 3D finite elements available in Abaqus sre systematically treated for elastic material at finite strain via Abaqus‐UMAT.
A finite volume approach to simulation of polymer melt flow in channels
Authors: Zdanski P.S.B. , Vaz M. , Inácio G.R. 
Published: April 2008

PurposeNumerical simulation of polymer injection processes has become increasingly common in mould design. In industry, such a task is accomplished mainly by using commercial packages. Owing to the complexities inherent of this class of problems, most commercial codes attempt to combine realistic rheological descriptions with simplified numerical models. In spite of the apparent success, such approaches are not able to capture important aspects of the flow topology. The present work aims to describe a more elaborate mathematical model based on finite volumes which is able to provide both accurate solutions and further insights on the physics of the polymer flow.Design/methodology/approachThe mathematical model comprises the momentum and energy equations and a Poisson equation for pressure to impose the incompressibility constraint. The governing equations are discretized using the finite volume method based on central, second‐order accurate formulas for both convection and diffusion terms. Artificial dissipation terms are added externally in order to control the odd‐even decoupling problem.FindingsThe numerical model was conceived within the framework of a generalized Newtonian formulation. The capability of the numerical scheme is illustrated by simulations using three distinct constitutive relations to approach the non‐Newtonian behaviour of the polymer melt: isothermal power‐law, modified Arrhenius power‐law and cross models.Originality/valueThis paper extends the computational strategies previously developed to Newtonian fluids to account for more complex constitutive relations. The velocity and temperature coupled solution for polymer melts using only second‐order accurate formulas constitute also a relevant contribution.
Mixed‐mode stress intensity factors of a three‐dimensional crack in a bonded bimaterial
Authors: Qin T.Y. , Zhu B.J. , Noda N.A. 
Published: April 2008

PurposeThis paper aims to calculate the mixed‐mode stress intensity factors (SIFs) of a 3D crack meeting the interface in a bimaterial under shear loading by a hypersingular integral equation (HIE) method, And further to assess the accuracy of numerical solutions for the mixed mode SIFs along the crack front.Design/methodology/approachA 3D crack modeling is reduced to solving a set of HIEs. Based on the analytical solutions of the singular stress field around the crack front, a numerical method for the HIEs is proposed by a finite‐part integral method, where the displacement discontinuities of the crack surface are approximated by the product of basic density functions and polynomials. Using FORTRAN program, numerical solutions of the mixed‐mode SIFs of some examples are presented.FindingsThe numerical method is proved to be an effective construction technique. The numerical results show that this numerical technique is successful, and the solution precision is satisfied.Research limitations/implicationsThis work takes further steps to improve the fundamental systems of HIE for its application in the fields of arbitrary shape crack problems. Propose several techniques for numerical implementation, which could increase the efficiency and accuracy of computation.Practical implicationsWhenever there is a structure containing the 3D crack, the analysis method described in this paper can be utilized to find the critical configurations under which the structure may be most vulnerable. In such cases, the strength predictions would be safer if the crack could be taken into account.Originality/valueThis paper is the first to apply HIE method to analyzing the mixed‐mode crack meeting the interface in 3D dissimilar materials. Numerical solutions of the mixed‐mode SIFs can give the satisfied solution precision.
Optimal structural design family by genetic search and ant colony approach
Authors: Kaveh A. , Shahrouzi M. 
Published: April 2008

PurposeGenetic Algorithm, as a generalized constructive search method, has already been applied to various fields of optimization problems using different encoding schemes. In conventional GAs, the optimum solution is usually announced as the fittest feasible individual achieved in a limited number of generations. In this paper, such a pseudo‐optimum is extended to a neighborhood structure, known as optimal design family.Design/methodology/approachIn this paper, the constructive feature of genetic search is combined with trail update strategy of ant colony approach in a discrete manner, in order to sample more competitive individuals from various subspaces of the search space as a dynamic‐memory of updating design family.FindingsThe proposed method is applied to structural layout and size optimization utilizing an efficient integer index encoding and its appropriate genetic operators. Different applications of the proposed method are illustrated using three truss and frame examples. In the first example, topological classes are identified during layout optimization. In the second example, an objective function containing the stress response, displacement response, and the weight of the structure is considered to solve the optimal design of non‐braced frames. This approach allows the selection of less sensitive designs among the family of solutions. The third example is selected for eigenvalue maximization with minimal number of bracings and structural weight for braced frames.Originality/valueIn this paper, a pseudo‐optimum is extended to a neighborhood structure, known as optimal design family.

Published: April 2008

PurposeThe purpose of this brief paper is to introduce the papers in this special issue of Journal of Managerial Psychology, focused on “Complexities and challenges in the work‐family interface”.Design/methodology/approachThe paper first introduces the theme of the special issue, and a brief outline of each paper contained in it is given.FindingsThere is concern that progress in the work‐family research area has been somewhat restricted and may have failed to take sufficient account of the complexity of work‐family issues.Originality/valueThe literature on the work‐family interface is complex, and theory in the field is uncertain and under‐developed. The papers in this special issue should further understanding of the challenges and complexities underscoring the work‐family interface.
The impact of work/family demand on work‐family conflict
Authors: Boyar Scott L. , Maertz Carl P. , Mosley Donald C. , Carr Jon C. 
Published: April 2008

PurposeThe current study seeks to argue that the constructs of work demand and family demand have been neglected in the work‐family conflict (WFC) literature. The authors aim to help clarify the definition and utilize direct measures of perceived work and family demand to test main effect, mediated, and interactive hypotheses.Design/methodology/approachA sample of 698 university employees participated in a comprehensive computer survey that considered various manifest indicators and multiple scales across work and family domains. Moderator hierarchical regression and LISREL 8.0 were used in analyzing the data.FindingsThe results indicate that both forms of demand have significant direct effects on work interfering with family (WIF) and family interfering with work (FIW). Both demand constructs partially mediate the effects of three categories of domain variables on the two forms of conflict. Finally, the work demand‐WIF relationship is found to be stronger for those with relatively high family centrality.Research limitations/implicationsA cross‐sectional design was used and may be problematic when examining relationships that occur over time. Further, capturing all scales with a single survey could result in common method bias, which may have inflated the predictive relationships.Practical implicationsOrganizations can work to reduce WFC by adopting family‐friendly programs that help employees balance work and family demands. Specifically, this study implies that organizations should find ways to hold constant or reduce perceptions of work and family demand, along with other direct antecedents of WIF and FIW.Originality/valueThis study provides a relatively comprehensive model of antecedents that can be useful in future research. The authors also examine interactive effects of demand and work‐family centrality on conflict using direct measures of perceived demand. Methodologically, the research improves on some past studies by measuring perceived demand directly and by not narrowing our sample to employees who are married or those with children. Hopefully, these contributions will help stimulate continued growth in the work‐family literature.
Effort‐reward imbalance, over‐commitment and work‐life conflict: testing an expanded model
Authors: Kinman Gail , Jones Fiona 
Published: April 2008

PurposeAlthough the effort‐reward imbalance (ERI) model of job stress has gained support in predicting employee health, it has rarely been examined in the context of the work‐home interface. This study aims to test an expanded ERI model in predicting work‐life conflict (WLC) in university employees. Three hypotheses relating to the ERI are tested. It is also predicted that lower organisational support for work‐life balance, less schedule flexibility and lower levels of separation between work and home life will lead to increased work‐life conflict.Design/methodology/approachIn this cross‐sectional study, 1,108 employees working in UK universities completed questionnaires assessing ERI, WLC, schedule flexibility, employer support and work‐life separation/integration.FindingsStrong main effects of job‐related efforts, rewards and over‐commitment on WLC are found. A significant two‐way interaction (effort×reward) and some evidence for a three‐way interaction effort×reward×over‐commitment) are observed. Perceived schedule flexibility and work‐life integration also make significant contributions to the variance in WLC. The final model explains 66 per cent of criterion variance.Research limitations/implicationsAs the study is cross‐sectional, causal relationships cannot be established.Practical implicationsThis study extends knowledge of the ERI model as a predictor of WLC. More research is required into ways in which effort‐reward inequity and over‐commitment might threaten work‐life balance, together with the working practices and organisational factors which might modify this threat.Originality/valueThe ERI model has rarely been examined in the context of the work‐home interface. The importance of effort‐reward imbalance and over‐commitment to WLC has been highlighted.
Examining couple agreement about work‐family conflict
Authors: Streich Michelle , Casper Wendy J. , Nicole Salvaggio Amy 
Published: April 2008

PurposeThis study aims to explore the nature of couple agreement about work‐family conflict, adding to previous research by explicitly testing the extent to which couples agree when rating work interference with family (WIF) and the influence of this agreement on other outcomes.Design/methodology/approachIn total, 224 dual‐earner couples were surveyed to assess their own WIF, as well as what they believed to be their partner's level of WIF. Participants also completed questions regarding their organizational commitment.FindingsCouples agreed when rating their own and their partners' WIF more than they disagreed. As predicted, couples agreed more when rating the female partner's WIF as compared to the male partner's WIF. Finally, couple agreement about WIF moderated the relationship between female WIF and her continuance organizational commitment such that the relationship between the female partner's WIF and her level of continuance commitment was stronger when agreement about her experienced WIF was low.Research limitations/implicationsThis was a convenience sample, and therefore caution should be used when generalizing to a broader population. Second, the research design was cross‐sectional, prohibiting causal inferences and conclusions about couple agreement over time.Practical implicationsOrganizations should consider the perceptions and attitudes of both employees and their partners, as both have implications for work attitudes. Organizations might benefit from considering ways in which they can involve and engage employees' spouses and partners, and could offer flexible schedules as a way to reduce employee work‐to‐family conflict and enhance both employee and partner attitudes toward the organization.Originality/valueThis paper contributes to the literature by exploring both self and partner perceptions of work‐family conflict and examining couple agreement about this conflict.
Positive effects of nonwork‐to‐work facilitation on well‐being in work, family and personal domains
Authors: Allis Pam , O'Driscoll Michael 
Published: April 2008

PurposeThe paper seeks to examine whether spillover from “nonwork” to work contributes to individuals' well‐being.Design/methodology/approachAn online survey was administered to New Zealand local government employees. Positive (facilitation) and negative (conflict) spillover from two “nonwork” domains (family and personal benefit activities) to work were investigated. The survey also assessed psychological involvement (in work, family and personal benefit activities), time devoted to each domain, and self‐reported well‐being in each area.FindingsLevels of nonwork‐to‐work facilitation were moderate, and significantly higher than nonwork‐to‐work conflict, and well‐being was moderately high (although greater for the family and personal benefit domains than for work). There were significant positive relationships between psychological involvement in the nonwork domains and levels of facilitation from these domains to work, and nonwork‐to‐work facilitation was associated with higher well‐being. Time invested in family and personal activities was not linked with greater nonwork‐to‐work conflict. Mediation analyses indicated that psychological involvement (in family and personal activities) was associated with increased facilitation, which in turn enhanced well‐being.Practical implicationsEngagement in family and personal benefit activities yields positive outcomes for individuals, in terms of their psychological well‐being and facilitation of work‐related outcomes. Encouragement to engage in these areas can therefore be beneficial for both individuals and their employing organizations.Originality/valueThe main contribution of this research is that involvement in personal benefit activities (as another component of the “nonwork” domain, in addition to family activities) can have positive outcomes for individuals, resulting in facilitation of work outcomes and positive well‐being.
The expatriate family: an international perspective
Authors: Haslberger Arno , Brewster Chris 
Published: April 2008

PurposeThis paper seeks to review and explore the relatively neglected notion of the adjustment of expatriate families to living abroad with the aim of developing a new model that can be used for future research.Design/methodology/approachThe paper draws on the few studies of the topic that have been carried out, but widens the search to include evidence from the related adjustment and family stress literature to create a new model of the process. Using the ideas of stressors, strains and hassles, capabilities, and shared meanings, the paper examines the situation of the expatriate family and explores how families can adjust to life in another country.FindingsBy adopting a salutogenic approach and incorporating insights from these other literatures, the paper shows that family adaptation is a complex and many‐faceted process. It is a process that greater awareness on the part of the family and the organization can improve.Research limitations/implicationsWith the help of the model of family adjustment the paper points to systematic gaps in studies on expatriate families and outlines a consequent research agenda.Practical implicationsAwareness is a crucial element in adjustment. The paper shows that awareness by the family can alleviate problems, and that organizations employing members of the family can assist in the adjustment process for the family.Originality/valueThe contribution of the paper comes in its attempt to encompass what is known about expatriate family adaptation directly with a wider view of family adjustment. This provides both a practical framework for future research and some practical implications.
