Individual values and the work/family interface
Authors: Cohen Aaron 
Published: November 2009

PurposeThe question of how to strike a balance between work and life is attracting increasing attention from both scholars and practitioners. This paper aims to examine the relationship between individual level values, using Schwartz's basic human values theory, and the work‐family conflict (WFC), the family‐work conflict (FWC), and coping strategies.Design/methodology/approachA total of 122 employees from two Israeli high tech companies participated in this survey. The portrait values questionnaire (PVQ) was used to measure ten basic values. The PVQ includes short verbal portraits of 40 different people, gender matched with the respondent. Work‐family conflict and family‐work conflict were measured by the scales developed by Netemeyer et al. Personal coping was measured using the 16 items of Kirchmeyer's scale of coping strategies. Regression and correlation analysis were used to test the research hypotheses.FindingsThe findings showed a strong relationship between power and the three independent variables. Schwartz's ten values explained a relatively large percentage of the variation in the work‐family conflict and the use of coping strategies.Originality/valueWhile there has been a growing trend to examine individual level values in order to better understand the attitudes and behaviors of employees in the workplace, very few studies have examined whether and how individual values are related to the interface between work and family. This paper responded to the call for such research. The findings are discussed in terms of their implications for the continuation of research on individual values in their relationship to the work‐family interface.
Real‐time collision detection and response techniques for deformable objects based on hybrid bounding volume hierarchy
Authors: Zhu Yuanfeng , Meng Jun 
Published: November 2009

PurposeThe purpose of this paper is to propose a physically plausible solution based on hybrid bounding volume (BV) hierarchy for real‐time collision detection (CD) and response between a deformable and a rigid object.Design/methodology/approachHybrid BV can be used to build BV hierarchy for the deformable object. The overlapping tests based on separating axis theorem (SAT) can be used to deal with CD. The physics conception of restitution coefficient and other important forces can be used to more real collision response.FindingsMany methods focus on a specific application, but none of them gives an approach to physically plausible, real‐time simulation of CD and response up to 10,000 of deforming primitives. The paper finds that hybrid BV AABB‐Sphere for deformable object could increase the efficiency for CD, and restitution coefficient and other important physical concepts could provide more real collision response.Research limitations/implicationsThe paper does not deal with all types of CD, such as CD for two deformable objects.Originality/valueUsing AABB‐Sphere hybrid BV to build hierarchical BV tree for deformable object, and OBB‐Sphere hybrid BV for rigid object. Owing to the variety of hybrid BV structures, during different phases of CD, different overlapping tests are used to accelerate CD effectively. Using important physics conceptions provides a good solution to simulate more real collision response.

Published: November 2009

PurposeComplex system modeling requires not only understanding of modeling framework but also domain knowledge of the system. The purpose of this paper is to present an approach which separates the domain knowledge from the modeling framework with different views.Design/methodology/approachBy establishing the mechanism of association and fusion among the views, the description and characterization of system from different aspect and point of view can form a complete system model. Based on the approach, a modeling and simulation (M&S) platform named SimFaster is developed. Modeling environment and simulation engine are the most important parts of the platform. The modeling environment provides multi‐views and multi‐layers to help the developers to modeling the structure, layers, composition, behavior, and interactions of an application system. The simulation engine provides mechanism of integration and interaction for components and objects, and provides runtime support for the concepts and terms from modeling environment. The simulation engine organizes the objects in the memory of distributed system as reflective object database system, so it is repository centered architecturally.FindingsBased on the approach of multi‐views modeling, the platform is a flexible framework and supports top‐down design, model reuse and interoperation, dynamic refinement of models, corporative design among different users in different stages, and the rebuilt of application rapidly.Research limitations/implicationsThis paper deals with high‐level models of the complex systems.Practical implicationsThis platform helps to design, modeling, and simulation complex system (especially for weapon combat system). It can participate into all the stages of the development of complex product/system, and can support the validation, refinement, optimization of models, and systems.Originality/valueThis paper presents a multi‐views modeling approach for the modeling of complex system.

Authors: EL‐Refaie Ayman M. , Zhu Z.Q. , Jahns Thomas M. , Howe David 
Published: November 2009

PurposePermanent magnet (PM) brushless machines equipped with fractional‐slot concentrated‐windings (FSCW) have been receiving considerable attention over the past few years, due to the fact that they have short end‐windings, a high‐slot fill factor, a high efficiency and power density, and good flux‐weakening and fault‐tolerance capabilities. A key design parameter for such machines is the phase winding inductance since this has a significant impact on the performance, as well as on the magnitude of any reluctance torque. The purpose of this paper is to describe a detailed investigation of the various components of the winding inductance in machines equipped with both overlapping and non‐overlapping windings and different slot/pole number combinations. It also examines the influence of key design parameters, which affect the inductance components, with particular reference to the inductances of machines in which all the teeth are wound and those in which only alternate teeth are wound.Design/methodology/approachThe paper analyzes and compares various inductance components which result from different winding configurations.FindingsIt is shown that the main component of the winding inductance is the relatively large slot‐leakage component. Both analytical and finite element models are employed and predicted results are validated on several prototype machines.Originality/valueSuch a thorough investigation of the various inductance components for these type of machines has not been presented before. The paper will serve as a good reference for engineers and researchers designing PM machines equipped with FECW.

Authors: Condon Marissa , Deaño Alfredo , Iserles Arieh , Maczyński Kornel , Xu Tao 
Published: November 2009

PurposeThe purpose of this paper is to analyse a novel technique for an efficient numerical approximation of systems of highly oscillatory ordinary differential equations (ODEs) that arise in electronic systems subject to modulated signals.Design/methodology/approachThe paper combines a Filon‐type method with waveform relaxation techniques for nonlinear systems of ODEs.FindingsThe analysis includes numerical examples to compare with traditional methods such as the trapezoidal rule and Runge‐Kutta methods. This comparison shows that the proposed approach can be very effective when dealing with systems of highly oscillatory differential equations.Research limitations/implicationsThe present paper constitutes a preliminary study of Filon‐type methods applied to highly oscillatory ODEs in the context of electronic systems, and it is a starting point for future research that will address more general cases.Originality/valueThe proposed method makes use of novel and recent techniques in the area of highly oscillatory problems, and it proves to be particularly useful in cases where standard methods become expensive to implement.
Identification of demagnetization faults in a permanent magnet synchronous machine by permeance network
Authors: Ahmed Farooq Jawad , Djerdir Abdesslem , Miraoui Abdellatif 
Published: November 2009

PurposeThe purpose of this paper is to present a novel method to identify demagnetization faults in the magnet of a permanent magnet synchronous machine (PMSM) using some externally measurable parameter.Design/methodology/approachThe machine is modelled by using permeance network theory. The new feature introduced in the permeance network is the subdivision of magnets into segments, modelled as bidirectional elements. These bidirectional elements allow taking into account the effect of one element on the other. To detect the demagnetization faults, a gradient‐based algorithm is also developed. This algorithm uses the permeance network model of the PMSM and measurement data of some parameter to find the distribution of remanent induction in the magnet segments.FindingsThe methodology presented is able to detect the demagnetization fault using an external data. The measurement data in this paper is obtained through finite element simulations. The fast and accurate convergence of the algorithm makes the model to find its place in magnet fault diagnosis. Results for different magnet fault types have been presented.Originality/valueThis new approach to detect demagnetization fault can serve as a step towards development of better fault‐detection algorithms and fault‐tolerant control schemes.
Prediction of iron loss in magnetic laminations under PWM voltage supply
Authors: Gmyrek Zbigniew 
Published: November 2009

PurposeThe purpose of this paper is to discuss a new method of iron loss estimation under pulse width modulation (PWM) converter supply. The proposed method concerns the longitudinal magnetisation.Design/methodology/approachA novel method of iron loss estimation applies values of iron losses that come from a single higher harmonic coexisting with a DC‐bias field. This method considers non‐linearity of ferromagnetic. Results of estimation are validated using experimental results.FindingsThe paper formulates that the dependence of iron losses come from harmonics, on DC‐bias field. Moreover, it formulates possibilities of their utilization to iron loss estimation in case of deformed flux. On the other hand, it discusses the influence of DC‐bias field on static hysteresis and classical eddy current losses.Research limitations/implicationsExperimental verification will still be needed as to the accuracy of the proposed model and applicability to various magnetic materials.Practical implicationsThe paper provides an easy mathematical method of iron loss estimation, under PWM voltage supply.Originality/valueThe paper explains how to use an analytical method and results of iron losses come from single harmonics, obtained under coexistence with DC‐bias field, to iron loss estimation in case of longitudinal magnetisation where deformed magnetic flux occurs.

The importance of self‐service kiosks in developing consumers' retail patronage intentions
Authors: Lee Hyun‐Joo , Fairhurst Ann E. , Lee Min‐Young 
Published: November 2009

PurposeThe purpose of this study is to examine ways in which service quality delivered by self‐service kiosks influences consumers' retail patronage intentions.Design/methodology/approachThe model was tested in two self‐service kiosk settings: self‐checkout and information kiosk. Survey participants were members of a consumer panel from an online survey agent. A total of 1,230 e‐mails were distributed. Of these, 600 usable surveys were used for data analysis. Data were analyzed using structural equation modeling.FindingsThe study demonstrates that service quality delivered by self‐service kiosks is a direct and an indirect determinant of consumers' retail patronage intentions; service quality delivered by self‐service kiosks directly influences consumers' retail patronage intentions and also indirectly influences consumers' retail patronage intentions through three dimensions of retail service quality (i.e. reliability, personal interaction, and problem solving).Originality/valueCompared with previous studies that were heavily focused on consumer acceptance or trial of self‐service technologies, the study attempts to address formerly unexplored aspects of self‐service kiosks' contribution to retail patronage. A second contribution of the study which makes it different from prior studies that were mostly conducted in the context of self‐checkouts is that it tests a conceptual model related to two types of self‐service kiosks (i.e. self‐checkout and information kiosk) to examine whether the proposed relationships are similar or dissimilar across the two types.
From little things big things grow: scaling‐up assessment of experiential learning
Authors: Quinn Diana , Shurville Simon 
Published: November 2009

PurposeThe new economies of the twenty‐first century require new approaches to learning and teaching from higher education (HE). Accordingly many universities have gradually scaled‐up learner‐centred approaches, including flexible delivery and technology‐enhanced learning, from the domains of enthusiasts towards the institutional level. This paper seeks to argue that these new economies and styles of learning and teaching bring similar requirements for scaling of assessment practices in HE, in particular, that it is now time for many universities to consider change initiatives to scale‐up the assessment of experiential learning to the institutional level.Design/methodology/approachThe need to scale‐up assessment of experiential learning in the Australian and international higher HE contexts is discussed and a variety of change initiatives to scale‐up assessment of experiential learning at the University of South Australia is described. These initiatives are explored in the wider context of change management in HE.FindingsAssessment of experiential learning is at a tipping point where it needs to transition from the enthusiasts towards the mainstream of academics. Support for this process is a new challenge for academic developers, educational technologists, librarians and other stakeholders, akin to other recent challenges such as mainstreaming flexible learning and technology‐enhanced learning. It is argued that for change to succeed learners and academics require local or regional evidence that experiential learning and its assessment are both beneficial and manageable.Originality/valueTaking assessment of experiential learning to the institutional level is a challenge that is reminiscent of the need to scale‐up flexible delivery and technology‐enhanced learning over the past decade. Information that can help universities to graduate large numbers of knowledge workers with appropriate graduate attributes developed through experiential learning should be beneficial to the graduates, the institutions and society at large.
Automating formative and summative feedback for individualised assignments
Authors: Hamilton Ian Robert 
Published: November 2009

PurposeThe purpose of this paper is to report on the rationale behind the use of a unique paper‐based individualised accounting assignment, which automated the provision to students of immediate formative and timely summative feedback.Design/methodology/approachAs students worked towards completing their assignment, the package provided immediate formative feedback with sufficient indicators for the student to identify that they had made an error and provided encouragement for the student to take appropriate corrective action until they were satisfied that their answer was correct. Once the student was satisfied with their work, their submission was automatically marked by the assessment package according to the pre‐set marking scheme.FindingsThe assignment experience reported here has shown the potential for interactive spreadsheets to be created for a wide range of rule‐based accounting problems to provide formative and summative feedback. The package can be (and has been) easily extended beyond financial accounting to many other accounting‐ and non‐accounting‐related fields, e.g. tax, audit, economics and statistics. In fact, individualised assignments utilising interactive spreadsheets appear to have broad applicability in any educational context (including mathematics, engineering and science) where a correct numerical answer is required.Originality/valueThe unique automated feedback and marking package was developed by the author utilising Microsoft's Excel spreadsheeting tool. The marking package generated a detailed summary providing important feedback to students clearly identifying correct answers and specific problem areas, enabling the student to review these aspects. The package also provided feedback to the teacher identifying the cohort's performance on each item in the assessment.
Developing team skills with self‐ and peer assessment
Authors: Willey Keith , Gardner Anne 
Published: November 2009

PurposeSelf‐ and peer assessment has proved effective in promoting the development of teamwork and other professional skills in undergraduate students. However, in previous research approximately 30 percent of students reported that its use produced no perceived improvement in their teamwork experience. It was hypothesised that a significant number of these students were probably members of a team that would have functioned well without self‐ and peer assessment and hence the process did not improve their teamwork experience. This paper aims to report the testing of this hypothesis.Design/methodology/approachThe paper reviews some of the literature on self‐ and peer assessment, outlines the online self‐ and peer assessment tool SPARKPLUS, and analyses the results of a post‐subject survey of students in a large multi‐disciplinary engineering design subject.FindingsIt was found that students who were neutral as to whether self‐ and peer assessment improved their teamwork experience cannot be assumed to be members of well‐functioning teams.Originality/valueTo increase the benefits for all students it is recommended that self‐ and peer assessment focuses on collaborative peer learning, not just assessment of team contributions. Furthermore, it is recommended that feedback sessions be focused on learning not just assessment outcomes and graduate attribute development should be recorded and tracked by linking development to categories required for professional accreditation.
Assessment of online discussion in work‐integrated learning
Authors: McNamara Judith , Brown Catherine 
Published: November 2009

PurposeThe purpose of this paper is to examine how online discussion can be used in work‐integrated learning as a vehicle for students to demonstrate their learning in the workplace and to facilitate collaborative learning where face‐to‐face classes are not feasible.Design/methodology/approachThe paper evaluates the use of assessable online discussion in facilitating collaborative learning and scaffolding reflection in work placement subjects. It reviews the literature regarding the use of online discussion, particularly for work placement subjects, and evaluates the use of an online discussion forum in a case study subject in the Queensland University of Technology (QUT) undergraduate law course.FindingsThe paper suggests that assessable online discussion forums are appropriate to facilitate student collaboration and collaborative learning in work placement subjects.Originality/valueThe paper is original in its examination of the assessment of online discussion in a work‐integrated learning context.
Behavioral dimensions of public relations leadership in organizations
Authors: Choi Jounghwa , Choi Yoonhyeung 
Published: November 2009

PurposeThe evolution of public relations into a management function has brought the importance of leadership to the forefront of professional discussion. This study aims to identify and develop a measure of behavioral dimensions critical to effective public relations for organization‐wide public relations leadership.Design/methodology/approachUsing a national survey of Public Relations Society of America (PRSA) members (n=159), a confirmatory factor analysis (CFA) was conducted on the seven theoretically‐driven leadership behaviors: upward influence, coordinating, internal monitoring, networking, representing, providing vision, and acting as a change agent.FindingsThe results suggest that the measurement model had a good internal and global fit. CFA results supported the seven‐factor model over the one‐factor model, suggesting that public relations leadership is multi‐dimensional. Among the behaviors, “providing vision” and “acting as a change agent” were those most strongly associated with the value of public relations in an organization.Originality/valueThe study shows that understanding public relations leadership from an organization‐wide perspective opens up a whole new avenue for future research to strengthen public relations as a management function. The present study also provides public relations managers with valuable insight concerning the leadership behaviors they can exercise to contribute to the value of public relations in their organizations.
