Children's experiences on the internet
Authors: Soeters Karen E. , van Schaik Katinka 
Published: June 2006

PurposeMore and more children have access to the internet. Surfing the web can be a wonderful experience but also one fraught with danger, and not all parents and educators are aware that children can be exposed to unsuitable content online. Another question rises, and that is what is disturbing for children online? Are there gender and age differences and very important what do children do when they encounter disturbing or harmful information? Aims to discuss this issue.Design/methodology/approachThis paper explores the positive and negative experiences of Dutch children on the web. It is based on a survey of 391 children aged eight to 13 years who have home access to the internet.FindingsChildren's most common positive experiences are playing games, using ICQ or MSN and chatting. Almost 50 percent of the respondents have had a negative experience on the internet. Children most frequently reported encountering pornography, followed by violence, computer viruses and/or their computers crashing. Approximately 80 percent told someone else about their negative experience, and, although it might be expected that this was a parent or a teacher, 45 percent of the children shared their experience with a friend.Practical implicationsOnly by knowing these facts can one start thinking about how one can make the Internet a safer place for children.Originality/valueThe survey also revealed several significant age and/or gender differences in how children experience the internet.

Published: June 2006

PurposeTo outline the structure and development of a library‐based Virtual Learning Environment (VLE) training programme at Waterford Institute of Technology (WIT) and to describe its origins, implementations and long‐term goals. To explain why WIT Libraries was prepared to diversify from its traditional role and to take on the challenges involved in this project.Design/methodology/approachCase study report on the VLE training initiative as it has progressed at WIT. Describes WIT Libraries' experience as the main instigator of the WebCT training programme at WIT and questions whether or not this has been an effective medium for the introduction of WebCT to WIT.FindingsConcludes by stating that the Library Unit is capable of implementing a varied, diverse and successful VLE programme. Stresses the importance of the personnel involved to the success of the project to date.Research limitations/implicationsThe project is still at an early stage of development. The study provides a short‐term view of one small academic library service's experience of implementing a VLE. No full‐scale user survey has been conducted to date.Practical implicationsThis account of WIT Libraries” experience of working with a VLE is likely to be a useful source of practical information for libraries in similar positions, of similar scale, faced with similar challenges.Originality/valueOffers practical solutions for libraries in similar positions. The successful diversification of the traditional library role is likely to be of interest to all members of the library profession.
Impacts of situational factors on buying decisions in shopping malls
Authors: Zhuang Guijun , Tsang Alex S.L. , Zhou Nan , Li Fuan , Nicholls J.A.F. 
Published: June 2006

PurposeTo investigate the impact of situational factors on mall shoppers' buying decisions.Design/methodology/approachBased on Belk's framework on situational factors in a sales situation, the study employed a dataset of mall shoppers in the USA, China and Hong Kong and logistic regression for analysis.FindingsIt is found that, whether in the combined sample or in the individual samples, nine of the 13 situational factors considered significantly affected shoppers' purchases of food or non‐food products. However, situational influences on purchases varied according to the types of products bought. More importantly, the findings on the impact of some factors were consistent across three or two samples, suggesting that their external validity may be extended to certain conditions.Research limitations/implicationsThe study had a limitation in the selection of the malls where the interviews were conducted, so some of the findings may be mall‐specific rather than representative of the general population of shoppers in the nations or regions.Practical implicationsThe information disclosed here may help the practitioners to better understand shoppers' (especially Chinese shoppers') behaviour in malls and, as a consequence, to undertake more efficient marketing strategies in malls (especially in the malls in China).Originality/valueThe distinguished feature of this paper is that it simultaneously examined the impacts of 13 situational factors on mall shoppers' purchase decisions with multinational data. This allowed researchers to check both the internal validity and the external validity of the observed impacts of the situational factors.
Antecedents of the difference in perceived risk between store brands and national brands
Authors: González Mieres Celina , María Díaz Martín Ana , Trespalacios Gutiérrez Juan Antonio 
Published: June 2006

PurposeThe present study sets out to analyze the effects that a set of variables related to purchasing behaviour has on the difference in perceived risk between store brands and national brands.Design/methodology/approachThe methodology proposed to achieve the objective consists of analyzing the existing relationship between different aspects relating to purchasing behaviour of the consumer and the difference in perceived risk between the two types of brands through a causal and integrated model. Such a model covers both the direct effects and the indirect effects caused by these variables jointly. In order to do so data were obtained from two groups of people, which has allowed for cross‐validation of the methodology used, which, in turn, permitted a greater generalization of the results.FindingsThe variables which have proven to be most relevant when explaining this difference are the perceived quality of the store as opposed to that of the national brands, familiarity with the store brands and confidence in the extrinsic attributes of the product to assess its quality.Originality/valuePrevious empirical research has focused primarily on the individual effects of these variables. A causal model is proposed capable of demonstrating that, besides the direct effect of a variable on the difference in perceived risk between store brands and national brands, there may be other ways for this variable to exercise its influence. This is important because of the implications for retailers when managing their own brands.
Pursuing opportunities
Authors: Grundvåg Ottesen Geir , Grønhaug Kjell 
Published: June 2006

PurposeAims to address the important but little researched question of why so many firms fail and so few succeed in their pursuit of opportunities.Design/methodology/approachBy reporting investment behaviour and performance among firms in the turbulent seafood industry, it was possible to raise important questions that guide the analysis of why some firms succeed while many fail in pursuing opportunities. Based on in‐depth interviews with top managers, the thinking and behaviour of one successful firm are analysed and compared with other less successful firms in the filleting branch of the seafood industry.FindingsShows with that the opportunity‐seeking behaviour of unsuccessful firms is influenced by over‐optimism, the success of other firms, and pressure to follow the “herd”. But also that the success of one firm addressed specifically is based on deep‐seated knowledge expressed as a simple rule that cuts through the various influences and guides its pursuit of opportunities.Research limitations/implicationsThe study focuses on a single industry and is limited to technology investments in manufacturing firms. An important implication is that, in turbulent environments, salient and positive information may easily overshadow the actual risk in pursuing apparently clear‐cut opportunities. This implies that opportunities and their associated threat(s) should be scrutinized carefully.Originality/valueProvides insights into the under‐researched question of why so many firms fail and so few succeed in their pursuit of opportunities.
Corporate universities: a catalyst for strategic human resource development?
Authors: Holland Peter , Pyman Amanda 
Published: June 2006

PurposeThe purpose of this paper is to consider the extent to which the concept of the corporate university is emerging as a simple re‐labelling of the functional training area or a key strategic platform in developing organisational competitive advantage.Design/methodology/approachA case study approach was taken to provide an in‐depth understanding of the development of a corporate university. Interviews with key informants and background/archival information was used to explore the focus of the corporate university. A typology developed by Taylor and Paton in 2001, was used to analyse the role and integration of the corporate university within the case study organisation.FindingsThe research indicates that the development of the corporate university within the case study organisation has focused resources to strategically develop their human capital and is clearly linked to the strategic objectives of the organisation to enhance competitive advantage.Research limitations/implicationsThe research was exploratory and whilst indicating a link between the corporate university and the organisation's objectives, this was a single case study. The limitations of single case study analysis prohibit generalisability. More research is needed to identify trends developing across industry sectors. From this a more detailed review of the impact of corporate universities can be made.Originality/valueThis is the first research into the strategic development of corporate universities in Australia. As such, it provides insight into the development of the phenomena in an advanced market economy. The initial findings indicate strategic development of the corporate university to support and enhance the organisations focus and competitive advantage.

Authors: De Gersem Herbert , Ion Mariana , Wilke Markus , Weiland Thomas , Demenko Andrzej 
Published: June 2006

PurposeTo propose trigonometric interpolation in combination with both sliding‐surface and moving‐band techniques for modelling rotation in finite‐element electrical machine models. To show that trigonometric interpolation is at least as accurate and efficient as standard stator‐rotor coupling schemes.Design/methodology/approachTrigonometric interpolation is explained concisely and put in a historical perspective. Characteristic drawbacks of trigonometric interpolation are alleviated one by one. A comparison with the more common locked‐step linear‐interpolation and mortar‐element approaches is carried out.FindingsTrigonometric interpolation offers a higher accuracy and therefore can outperform standard stator‐rotor coupling techniques when equipped with an appropriate iterative solver incorporating Fast Fourier Transforms to reduce the higher computational cost.Originality/valueThe synthetic interpretation of trigonometric interpolation as a spectral‐element approach in the machine's air gap, the efficient iterative solver combining conjugate gradients with Fast Fourier Transforms. The unified application to both sliding‐surface and moving‐band techniques.
Finite element analysis of saturation effects in a tubular linear permanent magnet machine
Authors: Demenko Andrzej , Mendrela Ernest , Szeląg Wojciech 
Published: June 2006

PurposeThe aim of the paper is to find the simple and accurate model for the analysis of a drive with a tubular linear permanent magnet machine (TLPMM). Attention is paid to the models that take into account the saturation effects and is useful in the calculations of electromagnetic forces.Design/methodology/approachA circuit model and a field‐circuit model (FCM) are considered. The FCM includes finite element (FE) formulation for the axisymmetric electromagnetic field, equations which define the connections of windings and converter elements, and expressions that describe the control system. The FE method is used to determine the parameters of the circuit model. In order to simplify the circuit model, saturation effects caused by armature reaction are ignored. The electromagnetic force calculation is based on the virtual work principle and uses an approximate expression for the derivative of system co‐energy. The results obtained for the proposed models have been compared.FindingsThe proposed FE method of force calculation conforms with the applied method of movement simulation. For the rotor position when the cogging force is equal to zero the calculated cogging force is “almost” zero within seven‐decimal‐place accuracy. The effects of armature reaction on the performance of a TLPMM machine are similar to those which occur in a classical DC machine; in particular the demagnetising effect caused by saturation is observed.Originality/valueThe paper shows the influence of the saturation effects on the electromagnetic force of a TLPMM. In the case of “strong saturation”, the classical circuit model may be inappropriate for engineering calculations.
Interpolation technique for effective determination of switching time instants for field‐circuit coupled problems with switching elements
Authors: Benderskaya Galina , De Gersem Herbert , Weiland Thomas , Clemens Markus 
Published: June 2006

PurposeTo provide a numerical technique for the quick and simple determination of the switching time instants for field‐circuit coupled problems with switching elements.Design/methodology/approach3D magnetic vector potential formulation coupled to an electrical circuit with switching elements, for example, diodes, is presented. The change of the state of the switching elements is implemented as a modification of the model topology.FindingsSince every step of the singly diagonally implicit Runge‐Kutta methods delivers not only the solution of this time step but also its stage derivatives, they can be efficiently employed to construct a dense‐output‐based interpolation polynomial, with their roots approximating the switching time instants.Originality/valueThis paper presents a computationally cheap interpolation approach for quick and accurate determination of switching time instances for field‐circuit coupled problems with switching elements. The proposed technique can be successfully incorporated into software packages designed to model coupled problems of different nature, where sudden changes of quality may take place.

Authors: Taïbi S. , Tounzi A. , Piriou F. 
Published: June 2006

PurposeAims to determine the magnetic parameters at no‐load of a variable reluctance machine excited by DC and AC currents.Design/methodology/approachPresents the linear analytical model used to determine the electro‐magnetic variables of a stator current excited reluctance machine. The 2D FEM approach is also introduced. Then the prototype designed in the laboratory is presented and its magnetic characteristics determined. The results are calculated using both models and compared with the experimental values.FindingsAccording to the different results, apart from the atypical E(Ie) characteristic, for both excitation models, the doubly slotted machine excited by current in the stator can be modelled in a manner similar to that of a smooth rotor synchronous machine with an electromagnetic gear box.Originality/valueThis paper has succeeded in determining the magnetic parameters at no‐load of a variable reluctance machine excited by DC and AC currents.
High frequency extension of non‐linear models of laminated cores
Authors: Roger D. , Napieralska‐Juszczak E. , Henneton A. 
Published: June 2006

PurposeThe paper gives a new measurement method of the parameters characterising the magnetic laminations for broadband low‐level signals defined at any operational point.Design/methodology/approachHigh frequency phenomena machines fed by PWM inverters are related to low‐level signals corresponding to minor hysteresis loops around the instantaneous working point, which moves on the main loop at the basic frequency. The minor loops are assimilated to ellipses, which are characterised by only two parameters: the incremental magnetic permeability (μ) and the electric conductivity (σ).FindingsFor small signals high frequency field components, the laminated steel behaviour can be described by two local parameters (μ,σ) and skin effect. The values ofμandσdo not depend on frequency up to 1 MHz, but only on the operating point.Research limitations/implicationsThe proposed broadband characterisation should be associated with a Priesach model that defines the operating point for computer simulation of high frequency phenomena.Practical implicationsThe broadband characterisation of magnetic laminations is useful for studying the behaviour of the windings of the PWM‐fed machines.Originality/valueBroadband measurements are now possible on small magnetic steel lamination samples.
The effect of strategic and tactical cause‐related marketing on consumers' brand loyalty
Authors: van den Brink Douwe , Odekerken‐Schröder Gaby , Pauwels Pieter 
Published: June 2006

PurposeThe first objective was to find out to what extent consumers reveal an effect of strategic and tactical cause‐related marketing on brand loyalty. Second, the article seeks to assess the moderating role of consumer involvement with a product on the relationship between cause‐related marketing and brand loyalty.Design/methodology/approachAn experimental design with 240 participants was used.FindingsThe results show that consumers perceive a significantly enhanced level of brand loyalty as a result of strategic cause‐related marketing as long as the firm has a long‐term commitment to this campaign and the campaign is related to a low involvement product. Consumers do not exhibit a significant impact of tactical cause‐related marketing campaigns – whether related to high or low involvement products – on brand loyalty.Research limitations/implicationsFirst, all respondents were students from a western European university. Second, the experiment relied on imaginary storyboards. Third, the program dimensions were not manipulated separately.Practical implicationsIf companies intend to increase brand loyalty through CRM they should set up long‐lasting CRM campaigns linked to the product that shows the lowest level of consumer involvement.Originality/valueThe added value of this paper is the link between cause‐related marketing programs and brand loyalty. Moreover, a distinction is explicitly made between tactical and strategic CRM programs.
Improving attitudes toward brands with environmental associations: an experimental approach
Authors: Montoro Rios Francisco J. , Luque Martínez Teodoro , Fuentes Moreno Francisca , Cañadas Soriano Paloma 
Published: June 2006

PurposeThe purpose of this article is to determine the relative importance of the ecological attribute when other attributes referring to the functional performance of a brand are taken into account, and check the effectiveness of environmental labels.Design/methodology/approachThe paper establishes an experiment in which 352 women responsible for the household shopping are exposed to different levels of environmental information. The study analyses the effect said information has on product attitude and purchase intention. In order to transmit the information, a leaflet specifically designed for the research was used.FindingsThis study confirms the presence of a positive effect of environmental associations on brand attitude, though this effect is smaller than that of other functional attributes. It also demonstrates that using independent environmental certifications strengthens beliefs in the product's ecological performance.Research limitations/implicationsThe use of washing powder can limit the feasibility of extrapolation of the results to other products. Therefore, a replication in other product categories is necessary/advisable.Practical implicationsIn the light of the results, using environmental associations certified by independent bodies is recommended. This would help improve both brand attitude and brand equity.Originality/valueThis paper increases the knowledge about the precise commercial usefulness of environmental associations in relation with other attributes.
Dimensions of consumer knowledge and its impacts on country of origin effects among Australian consumers: a case of fast‐consuming product
Authors: Phau Ian , Suntornnond Vasinee 
Published: June 2006

PurposeThe main purpose of the study is to extend Schaefer's paper by investigating how different dimensions of consumer knowledge may affect country of origin cues with an Australian sample.Design/methodology/approachA self‐administered mail survey was used in this study. The main sample consisted of Australian residents who are aged 18 and above and may or may not be alcoholic drinkers. The mailing list was purchased from a local council consisting of a suburb of metropolitan Perth, Western Australia. The total usable response rate was 38.7 per cent.FindingsThe results indicated that country of origin cues affect Australian consumers in beer evaluations despite its weak influences. It suggested that brand familiarity and objective product knowledge mediate the extent to which consumers relied on country of origin in product evaluation. However, the study found inconsistent results between different levels of objective knowledge and its effects on country of origin of manufacture.Originality/valueThe paper replicates Schaefer's with extensions. Despite the inconclusive results, objective product‐country knowledge, to some extent, may distort country of origin influences on consumers. This finding yields some insight for the efficiency in market segmentation. By segmenting consumers on different levels of knowledge, the marketers will subsequently make a better decision of how brand and country of origin should be managed.
Business relationships facing the end: why restore them?
Authors: Tähtinen Jaana , Vaaland Terje I. 
Published: June 2006

PurposeThis paper aims to discuss business relationships drawing to an end, and the reasons why company managers should attempt to restore the relationship instead of terminating it.Design/methodology/approachThe study applies a qualitative method and in‐depth interviews with companies in the North Sea oil industry.FindingsThe paper offers two contributions. First, it suggests an empirically grounded categorization of attenuating factors, i.e. the reasons to restore a relationship. Second, the categorization is extended to attenuating analysis, through which the value of the troubled relationship can be clarified. Thereafter, if the relationship is considered worth restoring, the managers may actively engage in restoring actions.Research limitations/implicationsBecause this study is limited to one business setting, future research applying the attenuating analysis to other industries by using action research is suggested.Practical implicationsThe study improves the awareness of inter‐organizational risk, enhances the manager's ability to assess the risk of losing a core relationship, and implements a method to reduce this risk. Troubled but valuable business relationships can be saved by applying the suggested attenuating analysis.Originality/valueTo one's knowledge, this is the first study that both systematically identifies the reasons for not leaving a business partner, and provides a practical framework for restoring a relationship based on the attenuating factors.
