Product recall crisis management: the impact on manufacturer's image, consumer loyalty and purchase intention
Authors: Souiden Nizar , Pons Frank 
Published: April 2009

PurposeThis paper aims to examine the impact of recall crisis management on the manufacturer's image, consumers' loyalty and future purchase intentions. More specifically, this research aims to clarify the types of recall strategies that companies put forward, as well as their impact on consumers' behaviors and perceptions of the manufacturer's image.Design/methodology/approachThe current study focuses on vehicle users who have either experienced automobile recalls or heard them discussed. Data were collected via car‐related web sites. The final sample comprises 573 people. The direction and strength of the relationships between various consumers' attitudes toward the different recall methods and their purchase intention are assessed through structural equation modeling (SEM).FindingsResults show that recalls contested by manufacturers have a significant negative impact on manufacturers' image, as well as on consumers' loyalty and purchase intentions. On the other hand, voluntary recalls or improvement campaigns have a significant positive impact on the manufacturer's image, as well as consumers' loyalty and purchase intentions.Research limitations/implicationsProactive strategies are the best solution to avoid a loss in consumer loyalty to the manufacturer during a recall crisis. In the contrary, manufacturers' adoption of reactive strategies harms their image, as well as consumers' loyalty. This translates into a negative impact on future purchase intentions and manufacturers' market share. This study concludes by recommending appropriate strategies to limit possible negative effects of product recalls.Research limitationsSome variables (such as media, the degree of severity of recalls and the frequency of recalls) are not investigated in this study. Additionally, the research is limited to the automobile industry. Other industries that also experience recalls (such as the pharmaceutical industry) might be considered in future research in order to confirm the consistency of the research findings.Originality/valueThe approach adopted by the current research is relatively different from earlier studies that directly link the types of recalls to the danger perceived by consumers that in turn affects their purchase intentions. In the current study, recalls indirectly impact purchase intentions principally via the manufacturer's image and brand loyalty. Additionally, the originality of this research stems from the fact that the manufacturer's image is considered as part of the changeable legacy of the company that itself may be affected by the “crisis situation,” not a stable asset.
Brand leadership and product innovation as firm strategies in global food markets
Authors: Gehlhar Mark J. , Regmi Anita , Stefanou Spiro E. , Zoumas Barry L. 
Published: April 2009

PurposeThis paper aims to understand the motivations for product innovation and brand leadership using a series of case studies focusing on firms with leading market positions of different types.Design/methodology/approachA qualitative study is presented of three leading food sector firms of different types (large/public, medium/private, and international/cooperative). An analysis of brand leadership is undertaken in the context of a conceptual framework linking process innovation, product innovation, and the firm's resource base and market orientation.FindingsThe cases suggest that process innovation supports product innovation as firms implement strategies to differentiate their products. Response to changing demand is a disciplined reaction where firms exploit their specialized resources using superior product knowledge and branding power. Leadership positions are maintained not only by responding to changing demand but by steering the market using innovative products and consumer education.Research limitations/implicationsThis study suggests that firms use their unique resource base and form strategies to capitalize on their capabilities. A single, dominant orientation is not necessary to maintain leadership. Rather process innovation can facilitate product innovation leading to successful product differentiation and enhancing a leadership position. The question of whether the growing power of retailers means the demise for branded food manufacturers is one that deserves attention. Innovation and its motivation is a national public policy concern that is influenced by a myriad of regulations and laws administered by various agencies.Originality/valueThis study is the first one to pull together the experiences of food‐firm brand leaders with their branding and innovation strategies as they look to the global arena for growth.
Adoption of electronic medical records: the role of network effects
Authors: Ayers Douglas J. , Menachemi Nir , Ramamonjiarivelo Zo , Matthews Michael , Brooks Robert G. 
Published: April 2009

PurposeThis paper aims to examine the role of network effects (defined as increased utility for users of a technology that occurs when adoption increases among other users) in the adoption of electronic medical records (EMR) systems. EMR systems, which have experienced slow adoption rates, promise to improve the efficiency of the healthcare system by facilitating information exchange among physicians caring for the same patients.Design/methodology/approachSurvey responses from physicians are used to test several hypotheses. The authors are interested in how market level EMR adoption was related to physician adoption intentions. The authors also test the “strong ties” notion of network effects by examining whether EMR adoption among generalists, and specialist physicians, had differing influences on adoption intentions in a given market.FindingsSupport for network effects is found; each one unit increase in market‐level EMR adoption is associated with a significant increase in overall physician adoption intention in that market. Secondary analyses suggest adoption of EMRs by specialists is significantly predictive of generalists' adoption intentions in a given market. However, as predicted, EMR among generalists does not influence other generalists' intentions; nor does EMR adoption by a specialists influence other specialists' intentions.Research implicationsNetwork effects play a role in the EMR adoption among physicians. Decision‐makers wanting to influence adoption should target defined market segments in an effort to build a critical mass of adoption then move to adjacent segments once network effects take hold.Originality/valueThis paper applies network effects theory to help explain the suboptimal adoption rates of an important healthcare technology.
Problem localization using probabilistic dependency analysis for automated system management in ubiquitous computing
Authors: Piao Shunshan , Park Jeongmin , Lee Eunseok 
Published: April 2009

PurposeThis paper seeks to develop an approach to problem localization and an algorithm to address the issue of determining the dependencies among system metrics for automated system management in ubiquitous computing systems.Design/methodology/approachThis paper proposes an approach to problem localization for learning the knowledge of dynamic environment using probabilistic dependency analysis to automatically determine problems. This approach is based on Bayesian learning to describe a system as a hierarchical dependency network, determining root causes of problems via inductive and deductive inferences on the network. An algorithm of preprocessing is performed to create ordering parameters that have close relationships with problems.FindingsThe findings show that using ordering parameters as input of network learning, it reduces learning time and maintains accuracy in diverse domains especially in the case of including large number of parameters, hence improving efficiency and accuracy of problem localization.Practical implicationsAn evaluation of the work is presented through performance measurements. Various comparisons and evaluations prove that the proposed approach is effective on problem localization and it can achieve significant cost savings.Originality/valueThis study contributes to research into the application of probabilistic dependency analysis in localizing the root cause of problems and predicting potential problems at run time after probabilities propagation throughout a network, particularly in relation to fault management in self‐managing systems.
Obligations of trust for privacy and confidentiality in distributed transactions
Authors: Mbanaso U.M. , Cooper G.S. , Chadwick David , Anderson Anne 
Published: April 2009

PurposeThis paper aims to describe a bilateral symmetric approach to authorization, privacy protection and obligation enforcement in distributed transactions. The authors introduce the concept of the obligation of trust (OoT) protocol as a privacy assurance and authorization mechanism that is built upon the XACML standard. The OoT allows two communicating parties to dynamically exchange their privacy and authorization requirements and capabilities, which the authors term a notification of obligation (NoB), as well as their commitments to fulfilling each other's requirements, which the authors term signed acceptance of obligations (SAO). The authors seek to describe some applicability of these concepts and to show how they can be integrated into distributed authorization systems for stricter privacy and confidentiality control.Design/methodology/approachExisting access control and privacy protection systems are typically unilateral and provider‐centric, in that the enterprise service provider assigns the access rights, makes the access control decisions, and determines the privacy policy. There is no negotiation between the client and the service provider about which access control or privacy policy to use. The authors adopt a symmetric, more user‐centric approach to privacy protection and authorization, which treats the client and service provider as peers, in which both can stipulate their requirements and capabilities, and hence negotiate terms which are equally acceptable to both parties.FindingsThe authors demonstrate how the obligation of trust protocol can be used in a number of different scenarios to improve upon the mechanisms that are currently available today.Practical implicationsThis approach will serve to increase trust in distributed transactions since each communicating party receives a difficult to repudiate digitally signed acceptance of obligations, in a standard language (XACML), which can be automatically enforced by their respective computing machinery.Originality/valueThe paper adds to current research in trust negotiation, privacy protection and authorization by combining all three together into one set of standardized protocols. Furthermore, by providing hard to repudiate signed acceptance of obligations messages, this strengthens the legal case of the injured party should a dispute arise.
Ubiquitous proximity e‐service for trust collaboration
Authors: Hwang Yuan‐Chu , Yuan Soe‐Tsyr 
Published: April 2009

PurposeThe authors seek to propose the notion of ubiquitous proximity e‐service for exploring collective wisdom in the ubiquitous environment. Ubiquitous proximity e‐service highlights the collective effort focused on collecting the user group's power as the reference for ubiquitous trust decisions.Design/methodology/approachThis paper provides some theoretical utility support for ubiquitous proximity e‐service. The “homophily” describes the tendency of individuals to associate and bond with similar others. By highlighting the “homophily” of e‐service participants, these isolated individuals can be treated as a group with proximity. The main value of ubiquitous proximity e‐service utilizes the network effect from the collective effort of interpersonal social network.FindingsIn order to leap the trust barrier for users to embrace these ubiquitous e‐services, ubiquitous proximity e‐service makes it possible for users to collaborate with their nearby user groups to establish a reliable and trustworthy interaction environment. The simulation outcomes for trust decision quality enhancement show a significant improvement in a variety of environment settings.Practical implicationsA significant value of ubiquitous proximity e‐service lies in the increased possibility of establishing innovative social network relationships. From the interpersonal perspective, unfamiliar strangers can make connections with individuals who are proximal and homoplastic to them. The strength of proximity gives people better chances to make interpersonal connections, including both weak ties and strong ties. By combining those interpersonal tie relationships, ubiquitous proximity e‐service can easily cause information diffusion and effectively encourage collective wisdom.Originality/valueThe paper advocates the utility of ubiquitous proximity e‐service that can be realized in the e‐commerce environment and which enables information diffusion effectively.
Security technologies based on a home gateway for making smart homes secure
Authors: Woo Kim Geon , Gyu Lee Deok , Wook Han Jong , Hyun Lee Seung , Wook Kim Sang 
Published: April 2009

PurposeThe purpose of this paper is to identify security technologies that are essential in making home network systems secure and to describe specialized security mechanisms for the home network and the relationships among them.Design/methodology/approachThe research model is designed to support three functions: authentication, authorization, and security policy. Authentication is tested in several methodologies such as id/pw, certificate, or bio; authorization is tested using RBAC methodologies; and security policy is specified using newly‐designed script language, such as xHDL.FindingsThe findings for “authentication” suggest that home network users can access services conveniently and securely. In addition, the findings for “security policy” suggest that security policy for home network requires specialized rather than general specification.Practical implicationsThe paper identifies three security functions essential for home network: authentication that supports most existing authentication mechanisms, so as to maximize user accessibility; authorization that is middleware‐independent and beyond the physical transport layer; and security policy optimized for the home network environment.Originality/valueThe paper focuses on an implementation‐based security model for the home network. Though interest and research in home network security are increasing, only limited authentication applications have been adopted in real deployment up to now. This paper introduces an integrated security model and emphasizes safety and convenience so as to promote reliability in home network services.
An efficient collusion resistant security mechanism for heterogeneous sensor networks
Authors: Hussain Sajid , Kausar Firdous , Masood Ashraf , Hyuk Park Jong 
Published: April 2009

PurposeAs large‐scale homogeneous networks suffer from high costs of communication, computation, and storage requirements, the heterogeneous sensor networks (HSN) are preferred because they provide better performance and security solutions for scalable applications in dynamic environments. Random key pre‐distribution schemes are vulnerable to collusion attacks. The purpose of this paper is to propose an efficient collusion resistant security mechanism for heterogeneous sensor networks.Design/methodology/approachThe authors consider a heterogeneous sensor network (HSN) consists of a small number of powerful high‐end H‐sensors and a large number of ordinary low‐end L‐sensors. However, homogeneous sensor network (MSN) consists of only L‐sensors. Since the collusion attack on key pre‐distribution scheme mainly takes advantage of the globally applicable keys, which are selected from the same key pool, they update the key ring after initial deployment and generate new key rings by using one‐way hash function on nodes' IDs and initial key rings. Further, in the proposed scheme, every node is authenticated by the BS in order to join the network.FindingsThe analysis of the proposed scheme shows that even if a large number of nodes are compromised, an adversary can only exploit a small number of keys near the compromised nodes, while other keys in the network remain safe.Originality/valueThe proposed key management scheme described in the paper outperforms the previous random key pre‐distribution schemes by: considerably reducing the storage requirement, and providing more resiliency against node capture and collusion attacks.
Marketing: philosophy of science and “epistobabble warfare”
Authors: Rod Michel 
Published: April 2009

PurposeThe purpose of this paper is to review the philosophy of science debates in the marketing literature and describe the current situation in marketing with respect to philosophy of science issues.Design/methodology/approachAs a viewpoint/conceptual paper, the approach is largely a review of the literature with interspersed personal commentary.FindingsThe paper summarises the key contentions of opposing academics and attempt to convey the futility and pointlessness of such argumentation and describe a novel (to marketing) “attitude” to conducting marketing research.Originality/valueRather than argue one particular perspective, it is this paper's central thesis that no one philosophical perspective does or should have a monopoly on what constitutes making a useful contribution to our understanding of marketing phenomena.
Decision system analysis of advertising agency decisions
Authors: Na WoonBong , Marshall Roger , Woodside Arch G. 
Published: April 2009

PurposeThe purpose of this paper is to report the use of decision system analysis (DSA) mapping the streams of communications (i.e. interactions), thoughts, actions and decisions involved for advertising agencies as executives in these firms gain client approval, and design creative, promotional and media strategies.Design/methodology/approachThis study uses DSA. This little‐used technique requires protocol analysis, interviews and observation before transcription of the organizational decision processes into flow charts.FindingsThe research first identifies four models, describing four specific decision types, then derives a general model from them. Executives from four agencies not in the original sample later confirms the models. The models generally confirm the existing knowledge base, with a few minor exceptions.Research limitations/implicationsThis qualitative technique suffers the common malady of the researchers losing objectivity because of their immersion in the case‐companies. Wherever possible the research employs quantitative techniques to verify observational judgments.Practical implicationsThe “thick description” and the summary charts of the advertising agency decision processes have the potential to aid agency decision makers to better structure their decision processes.Originality/valueThe findings themselves are of significance to those involved in the advertising industry, and there is an element of originality in the classification and the thick descriptions of advertising agency decision systems. The resurrection of DSA and the demonstration that the technique is viable and valuable is also a contribution of the study.
“Emergent inquiry”
Authors: Keegan Sheila 
Published: April 2009

PurposeThe purpose of this paper is to address the emerging way in which qualitative research is now carried out within the commercial world, the influences of shifting paradigms and the importance of theoretical understanding for current practice.Design/methodology/approachThe “method” underpinning this paper is qualitative observation drawn from research across a wide range of client companies during more than 30 years of commercial qualitative practice, as well as from recent, ongoing conversations with other commercial practitioners and academics, and from the academic and literature.FindingsCommercial qualitative research has, largely, moved away from a classic scientific paradigm towards a social constructionist perspective. The paper explores how the concept of emergence derived from complexity sciences and the contribution of neuroscience to understanding the role of emotion in judgement and decision making, can help make sense of current commercial practice.Practical implicationsThe implications for commercial practitioners are highlighted. Training in analytical skills and emotional awareness as reflection‐in‐action is needed in order that analysis and interpretation are embedded within the ongoing research process, i.e. training needs to include qualitative thinking as much as practice.Originality/valueThe paper highlights the creative potential of “emergent inquiry”, improvisation “in the moment” and the particular skills required.
The great transformation in business and society
Authors: Dolan Simon L. , Raich Mario 
Published: April 2009

PurposeThe purpose of this is to trace the current changes in business and society and identify the forces that shape the new landscape. It is argued that any attempt to continue business as usual is doomed to fail.Design/methodology/approachThe paper describes the change of paradigms that is taking place, and calls for respective alignment of business and political leaders. It further proposes that failure to perceive the changes or to take action, will lead to catastrophic consequences for people, organizations and society.FindingsThe paper concludes that there is a great need to change the fundamental principles of society away from dominance towards partnership and care; to change the fundamental paradigms which have stimulated the economy for centuries away from growth, towards transformation; to change the fundamental values underlying business from financial gain towards balanced values. The impact on economy and business would be far‐reaching, shifting their roles to focus on the real needs of people and society.Originality/valueThis paper proposes a roadmap to managing in tomorrow's landscape and is a wake‐up call to all people concerned with the future of our planet – political and business leaders, and scholars who conduct cross‐cultural research. Social responsibility needs to be taken seriously, and investment made in the future. Business and political leaders need to take the helm in this endeavor, and the role of the scholarly community is to provoke them to act.
