Developing a stakeholder analysis to aid bio‐based product innovation
Authors: McDonald Gael M. , Killerby Shaun , Maplesden Frances , Rolland Deborah 
Published: September 2007

PurposeThe results which that study seeks to report are the first part of a larger research programme funded by the New Zealand Foundation for Research, Science & Technology (FRST) aimed at gaining a better understanding of stakeholder perceptions in relation to bio‐based products.Design/methodology/approachUtilising three chemically modified wood products, data were collected from focus groups and questionnaires and centred primarily on perceptions surrounding the acceptability of building materials that have been bio‐modified. Irrespective of the type of chemical modification, family health and durability were the most important factors identified.FindingsThe study finds that product cost rated lower in the 16 factors evaluated, and energy used in production was of little concern. When comparing the three products to one another, two distinct groups with quite differing purchasing philosophies were identified and these perspectives significantly influenced perceptions of product acceptability and willingness to purchase. Utilising a paired comparison technique, an investigation of trade‐offs indicated preference for performance over cost and product familiarity. Similarly, low chemical emissions were also preferred over cost considerations. Among the findings, there was scepticism regarding trust in manufacturers to adequately safeguard health and safety and to have a minimum impact on the environment. Low levels of trust were expressed in regard to manufacturers' concern for future generations.Originality/valueThe paper develops an investigative framework which could be applied to the evaluation of products arising from bio‐material technology innovation and recommendations for future research directions.
Understanding price premium for grocery products: a conceptual model of customer‐based brand equity
Authors: Anselmsson Johan , Johansson Ulf , Persson Niklas 
Published: September 2007

PurposeThis paper seeks to develop a framework for understanding what drives customer‐based brand equity and price premium for grocery products.Design/methodology/approachThe paper reviews empirical studies made within the area of brand equity and studies of grocery products. It compares and analyses the results from an explorative and qualitative field study with previous research on brand equity and food quality.FindingsThe study finds that brand equity and price premium focusing on the grocery sector specifically highlights the role of uniqueness, together with the four traditionally basic dimensions of brand equity proposed: awareness, qualities, associations and loyalty. Relevant brand associations (origin, health, environment/animal friendliness, organisational associations and social image), and quality attributes (taste, odour, consistency/texture, appearance, function, packaging and ingredients) specific to groceries are identified and proposed for future measurement scales and model validating research.Practical implicationsThe development of a customer‐based brand equity model, that adds awareness, associations and loyalty to previous discussions on price and quality, brings to the table a more nuanced and multi‐faced tool for marketing of consumer packaged food.Originality/valueThe paper provides a framework for understanding, evaluating, measuring and managing brand equity for grocery products. As this paper presents the first conceptual brand equity framework for groceries, there is a contribution to research on food branding. Also, there is a contribution to the general field of brand equity as previous models have been very general.
Asymmetric quality‐tier competition: an alternative explanation
Authors: Sivakumar K. 
Published: September 2007

PurposeThis paper aims to offer an alternative explanation for asymmetric quality‐tier competition.Design/methodology/approachA conceptual framework based on quality‐price tradeoff is used in the study to derive research hypotheses and scanner panel data are used for empirical validation.FindingsThe paper finds that the concept of tradeoffs offers a simple explanation for asymmetric competition in favor of high quality brands; as the quality differential increases, asymmetry increases; as the price differential increases, the asymmetry decreases.Practical implicationsThe framework and findings can inform pricing strategies for brands in different quality tiers.Originality/valueThe paper offers an alternative explanation for asymmetric competition.
Late bidding and the auction price: evidence from eBay
Authors: Hou Jianwei 
Published: September 2007

PurposeThe purpose of this study is two‐fold. First, this study aims to examine how late bidding may have an effect on the auction price. Second, this study seeks to investigate how this effect can be moderated by different types of auctions.Design/methodology/approachData on computer CPUs were collected at eBay. A multiple regression analysis was performed to examine the effect of late bidding on price.FindingsEmpirical results indicate that late bidding decreases the auction price and the result is robust. This study, however, does not find support for the moderating role of the auction type (IPV vs APV) on the effect of late bidding on price.Research limitations/implicationsThis paper selects an extremely competitive market with many sellers and bidders. Future research may expand this study by examining late bidding under different combinations of market structures (competitive vs less competitive) and auction models (IPV vs APV vs CV).Originality/valueThis paper is the first study that empirically tests the effect of late bidding on the auction price.
Branded generations: baby boomers moving into the seniors market
Authors: Dann Susan 
Published: September 2007

PurposeThe purpose of this paper is to highlight the issues that arise for marketers and consumers in the branding of generational cohorts, with a focus on the baby boomers recent encroachment into the seniors market.Design/methodology/approachThe paper reviews current knowledge of the brand characteristics of the baby boom generation and their consumption patterns compared to traditional seniors.FindingsThe paper finds that baby boomers, although now in their 40s to 60s, are perceived by marketers as a generational brand which is different from the objectively defined seniors market which, based on seniors membership organisations, starts at age 50.Practical implicationsGiven the changing consumption patterns of baby boomers when compared with prior generational cohorts at the same age, brands need to reflect this generation's perceptions of itself to appeal the 50 plus market.Originality/valueBecause of the world wide phenomenon of the ageing of the population, the 50 plus market is the fastest growing and wealthiest market in developed countries. A better understanding of the influence of generational cohorts as opposed to age as a segmentation and positioning variable will result in more effective targeting of this cohort.
Supporting network access and service location in dynamic environments
Authors: Kutscher Dirk , Ott Jörg , Bartsch Steffen 
Published: September 2007

PurposeThis paper aims to discuss large‐scale operational aspects for network service maps and to present technical solutions and evaluation results.Design/methodology/approachThe paper reviews related work on service discovery specifically for wireless networks and services in, introduces network service maps and their operation in detail and describes their implementation and addresses two specific usage scenarios, based upon which it evaluates its approach through measurements and simulations.FindingsThe paper finds that, in the presence of today's ever‐increasing WLAN services, better support for service selection and automated service configuration is an urgent need to enable people to access these new services efficiently and thus increase their value and utilisation further. This is clearly reflected in different solutions being developed by service providers, roaming operators and device manufacturers that aim to facilitate WLAN usage.Originality/valueThe ubiquity of WLAN services, ranging from campus networks to commercial hotspots and community WLAN services, requires a new approach for automatically locating and using services. The paper presents a service selection infrastructure that is independent of a user's current network attachment and location in a way that users can obtain information of a specific network (or any other service) without being required to be connected to a particular one. Information about networks and services are distributed in a way that allows for using this information offline, e.g. when still looking for appropriate network access.
Towards interconnecting the Nordic identity federations
Authors: Tveter Walter M. , Melve Ingrid , Linden Mikael 
Published: September 2007

PurposeThis paper aims to outline considerations for trust management between established national identity federations in education and research. It also aims to discuss policy issues related to cross‐federation and to compare existing academic identity federations. The paper seeks to investigate Nordic national federations and to introduce the Kalmar Union as a means of interconnecting the Nordic federations.Design/methodology/approachThe paper discusses various issues in the policy of a cross‐federation, and suggests further work for developing the Kalmar Union Charter.FindingsThe paper finds that the technology used in federated identity management becomes more and more standardised, the technological challenges in making cross‐federations become fewer. Therefore, the remaining obstacles seem to be missing legislative know‐how, causing lack of sound information for decision makers. Thus, in an identity federation, trust establishment is, in the first place, a policy issue, not a technical one.Originality/valueIn recent years, several identity federations have been established in higher education around the world. Existing federations have a national scope, but the need for cross‐border services has led to the first interconnects of national federations. The Kalmar Union has been established as a cross‐federation of the Nordic academic identity federations.
Setting up a Grid‐CERT: experiences of an academic CSIRT
Authors: Möller Klaus 
Published: September 2007

PurposeGrid computing has often been heralded as the next logical step after the worldwide web. Users of grids can access dynamic resources such as computer storage and use the computing resources of computers under the umbrella of a virtual organisation. Although grid computing is often compared to the worldwide web, it is vastly more complex both in organisational and technical areas. This also extends into the area of security and incident response, where established academic computer security incident response teams (CSIRTs) face new challenges arising from the use of grids. This paper aims to outline some of the organisational and technical challenges encountered by the German academic CSIRT, DFN‐CERT while extending and adapting their services to grid environments during the D‐Grid project.Design/methodology/approachMost national research and education networks (NRENs) already have computer security incident response teams to respond to security incidents involving computers connected to the networks. This paper considers how one established NREN CSIRT is dealing with the new challenges arising from grid computing.FindingsThe paper finds that D‐Grid Initiative is an ongoing project and the establishment of CSIRT services for grids is still at an early stage. The establishment of communication channels to the various grid communities as well as gaining of knowledge about grid software has required DFN‐CERT to make changes even though the basic principles of CSIRT operation remain the same.Originality/valueThe D‐Grid project aims to establish a common grid infrastructure that can be used by other scientific domains. The project consists of six community projects and one integration project (DGI – D‐Grid Integration). The DGI project will develop the basic infrastructure, while the community projects will build on this infrastructure and enhance it for the specific needs of their research areas. At the initial stage of the DGI project, the idea of a central CSIRT for all grids in Germany was seen as an advantage over having a CSIRT for each grid project, which would have replicated efforts and thus wasted resources. This paper gives an overview about the organisational and technical challenges and experiences DFN‐CERT has encountered while setting up a CSIRT for the D‐Grid communities.
Utilising IPv6 over VPN to enhance home service connectivity
Authors: Huhtanen Karri , Silverajan Bilhanan , Harju Jarmo 
Published: September 2007

PurposeThe number of home networks, as well as the number of services and hosts in them, is increasing. Often home users cannot get public IPv4 network allocations from service providers and are forced to use network address translation (NAT) and port forwarding to solve connectivity issues to the different home services. This paper seeks to introduce a secure connectivity solution utilising both IPv6 and IPv6 transition mechanisms in cooperation with existing virtual private network (VPN) solutions.Design/methodology/approachThe proposed solution to avoid route conflicts and other problems with private IPv4 address space collisions is to utilise 6to4, an IPv6 transition mechanism, to obtain routable IPv6 network addresses first for the home network and services and then, to utilise the same IPv6 network for connectivity by bridging it over a VPN connection to the mobile terminal.FindingsThe paper finds that the adoption of this solution and these technologies will depend on how useful they are seen by vendors or service providers and included in their products. Regular vendors and service providers probably want to wait until there is a greater customer need. On the other hand, customers do not know about the possibilities before they are shown to them in practice. The best approach to this challenge is to find a cooperating vendor, or even better, a service provider willing to develop the concept further and to integrate it into the devices and services they are already offering.Originality/valueThe technologies for enhancing home service connectivity are already available. In the proof‐of‐concept implementation the paper has shown that all these components can be integrated and utilised to build home routers for present and future home networks. The technical disadvantages and challenges are solvable with further work and the whole concept is ready to be turned into products and services. As indicated in the paper, one of the issues for further work is to find and convince a vendor or service provider to integrate the proposed solution in their home router.
i2CAT experiences in advanced SIP‐based communications
Authors: Trapero Jordi , Novell Pol , Figuerola Sergi , Raspall Frederic 
Published: September 2007

PurposeThis paper aims to examine the design and implementation of an advanced ToIP platform for the interconnection of ToIP operators based on the concept of multilateral peering, with a special focus on the design requirements and implementation.Design/methodology/approachBased on the key design requirements of a ToIP peering platform analysed at the beginning of the document, an open source‐based network architecture is proposed. Subsequently, a detailed explanation of the elements and their functionalities that integrate both core platform and management platform is presented.FindingsThe paper finds that open source‐based ToIP platforms provide a cheap solution for deploying ToIP services such as ToIP peering. Although not as stable as hardware‐based ToIP platforms, software‐based platforms provide a very scalable high‐performance solution for delivering customised ToIP services.Research limitations/implicationsThe paper studies the implementation of advanced VoIP services such as video telephony and the call termination in public switched telephony network or mobile networks.Originality/valueThe deployment of an experimental ToIP peering platform in Catalonian will help to the large‐scale adoption of ToIP by both enterprise and residential customers. Furthermore, operators can reduce both capital and operating expenditures if they exchange traffic through the ToIP peering platform, reducing, thus, the cost of ToIP calls to end users.
Evaluation of scalable CAPEX models in ASON/GMPLS‐based IP networks
Authors: Szegedi Péter 
Published: September 2007

PurposeThis paper deals with a cost‐related evaluation and a comparison of the problems that arise on pure IP networks (i.e. big fat routers), IP over static optical networks (i.e. IP over synchronous digital hierarchy/optical transport network (SDH/OTN)) and IP over ASON/GMPLS‐based dynamic optical network architectures. The aim is to develop easy‐to‐use CAPEX models, which can be evaluated using statistical parameters to describe the actual network and the traffic characteristics. Since there are no experimental results on these statistical parameters that can be practically used in real networks, the CAPEX model should be not only general, but also scalable enough to evaluate the network cost in extreme situations.Design/methodology/approachIn this paper, the comparative CAPEX models are developed (in the framework of the IST Project MUPBED – Multi‐Partner European Test Beds for Research Networking) and the practical parameters are defined. Then the models are applied for the cost evaluation of a pan‐European research network based on the GÉANT2 network topology to validate the simplified comparison technique that is proposed.FindingsThe simulation results prove, on one hand, the applicability of the simplified cost models and on the other hand, the cost efficiency of the “IP over ASON/GMPLS” architecture.Originality/valueThis paper deals with a cost‐related evaluation and a comparison of the problems that are arise on pure IP networks, IP over static optical networks and IP over ASON/GMPLS‐based dynamic optical network architectures.
Education unbound
Authors: Abeles Tom P. 
Published: September 2007

PurposeThe rapid rise of Multi‐User Virtual Environments (MUVEs) or Metaverses, presents opportunities and challenges for the societies in the physical world and a particular challenge for education. This work aims to identify the key issues confronting education as it moves from its cohort model, K‐16, to an evolving life long experience, P‐to‐Gray, decoupling certification from knowledge acquisition.Design/methodology/approachExperimentation with MUVEs in education are combined with a review of the critical literature to yield an analysis of the current situation.FindingsEducation is evolving, and the MUVE's are also evolving both technically and culturally. Thus we will see significant changes in both current, brick space, education as well as e‐learning.Practical implicationsEducation will be life‐long learning, often ungraded, and blended between brick spaced learning and participation in virtual cultural experiences.Originality/valueMirror worlds, or simulations, will be important, not just in the current “brick‐space”, but also in the virtual worlds which will be accepted as one accepts “travel abroad”.
The journal is dead, long live the journal
Authors: Kingsley Danny 
Published: September 2007

PurposeThe purpose of this paper is to argue that the traditional scholarly journal system is outdated and in need of revamp, and new internet technologies provide opportunities for change unavailable until now.Design/methodology/approachThe four functions of the scholarly journal: registration; awareness; certification; and archiving are discussed in turn and alternative ways of undertaking those functions are explored. Barriers to change and ways to overcome these barriers are addressed.FindingsThe functions of registration and certification are already met with an open peer review system in place for some high profile journals. Recently developed searching and browsing facilities give academics access to a greater proportion of scholarly literature, providing a more efficient awareness function than traditional journals. The function of archiving is not being adequately addressed by commercial publishers, and the steps being taken by institutional repositories to that end are more sustainable. The fundamental tenet of science as part of the public domain is being eroded by commercial gain, and a move away from the traditional scholarly system can reverse that trend. Barriers to change are: the publisher's commercial imperative to maintain the status quo; the academy's reluctance to change; and the reward system. However, recently both publishers and academics have demonstrated a willingness to try new systems. The barrier of institutional reliance on metrics poses the greatest threat to change.Originality/valueThis paper builds on an historical background of arguments dating back to 1926, but uses up‐to‐date examples of ways publishers are moving towards change. The paper will inspire debate in the scholarly community.
Provocations on the structure of scholarly writing in the digital era
Authors: Kearns Jodi , O'Connor Brian C. , Moore Francisco B.‐G. 
Published: September 2007

PurposeThis paper seeks to urge academic writers to restructure their scholarly writing to reflect the depth of their intellectual message rather than conforming to the structurally simplistic hegemony of the mundane.Design/methodology/approachThe authors of this paper represent interdisciplinary perspectives in research. Each has grown increasingly disillusioned by dwindling consideration given to the structural integrity of scholarly thoughts in academic writing. This paper does not suggest a solution of strict adherence to some style manual or single format, nor does it suggest a privilege to any particular constraint. Indeed, the authors suggest that the digital environment enables unimagined communication possibilities, and hence a counterpoise to any single rigid structure. New formats require attention to the engineering of message structure. Using historical examples and modern applications from their disciplines, the authors offer provocations on the structures of scholarly writing. They pay particular attention to modern applications of Claude Shannon's information theory and to the introduction of models for understanding the audiences of academic writing.FindingsScholarly writing warrants a deep investment of intellectual, personal, and communicative effort. Readers will have different requirements for any individual piece of scholarly writing, but all will be served by the fullest expression of the logic, care, tenacity, and passion that drove the research to fruition. Engineering the scholarly document to contribute to audiences of differing interests and abilities requires careful consideration rather than mere assumption of a generic reader.Originality/valueResearch for this paper yielded few preceding studies that considered document structures for scholarship. Authors of this paper intend to provoke academes to engage in active and intentional reconsiderations of how they choose to say what they have to say, by following the presented examples of writing and tools for measuring structural elements of documents.
