Cites survey evidence that many firms undertaking e‐commerce projects do not appraise or evaluate them in traditional ways and discusses how businesses can deal with the many perspectives involved. Illustrates the “four faces of e‐business”, lists its benefits and considers seven legal/regulatory issues which require review in this context. Identifies three critical success factors for e‐business, shows some international growth forecasts and compares three financing models for e‐services. Briefly describes how some companies deal with security on the internet, sees e‐business as “imperative” for business success and warns that, although no single strategic model fits all companies, a strategy must be developed to avoid reducing returns on investment.

The purpose of this paper is to introduce and analyze a new blast-wave impact-mitigation concept using advanced computational methods and tools. The concept involves the use of a protective structure consisting of bimolecular reactants displaying a number of critical characteristics, including: a high level of thermodynamic stability under ambient conditions (to ensure a long shelf-life of the protective structure); the capability to undergo fast/large-yield chemical reactions under blast-impact induced shock-loading conditions; large negative activation and reaction volumes to provide effective attenuation of the pressure-dominated shockwave stress field through the volumetric-energy storing effects; and a large activation energy for efficient energy dissipation. The case of a particular bimolecular chemical reaction involving polyvinyl pyridine and cyclohexyl chloride as reactants and polyvinyl pyridinium ionic salt as the reaction product is analyzed.

Direct simulations of single planar shockwave propagations through the reactive mixture are carried out, and the structure of the shock front examined, as a function of the occurrence of the chemical reaction. To properly capture the shockwave-induced initiation of the chemical reactions during an impact event, all the calculations carried out in the present work involved the use of all-atom molecular-level equilibrium and non-equilibrium reactive molecular-dynamics simulations. In other words, atomic bonding is not pre-assigned, but is rather determined dynamically and adaptively using the concepts of the bond order and atomic valence.

The results obtained clearly reveal that when the chemical reactions are allowed to take place at the shock front and in the shockwave, the resulting shock front undergoes a considerable level of dispersion. Consequently, the (conserved) linear momentum is transferred (during the interaction of the protective-structure borne shockwaves with the protected structure) to the protected structure over a longer time period, while the peak loading experienced by the protected structure is substantially reduced.

To the authors’ knowledge, the present work is the first attempt to simulate shock-induced chemical reactions at the molecular level, for purposes of blast-mitigation.

Families conduct their affairs through processes that are built upon those of previous generations and also social capacities such as culture, class, oppression and poverty. The media has played a part in stereotyping the lower classes through their portrayal on the television programmes such as Benefits Street and Jeremy Kyle and tabloid newspaper stories. This chapter is a case study of two families who are at the opposing ends of the social scale, the Horrobin/Carter and Aldridge families. The two families were chosen due to them being linked by marriage in the younger generation. Through the use of genograms, we explore how the families differ in their attitudes towards relationships within their individual families, and also how they relate to each other as separate family groups. Despite the many differences, there are also a number of key similarities, particularly regarding the key females in the families, in terms of family background and snobbery. We also show that there is little family loyalty in the more privileged family and a power differential between the two families (oppressors vs. oppressed) in terms of the crimes committed.

In the recent work, a new blast-wave impact-mitigation concept involving the use of a protective structure consisting of bimolecular reactants (polyvinyl pyridine+cyclohexyl chloride), capable of undergoing a chemical reaction (to form polyvinyl pyridinium ionic salt) under shockwave loading conditions, was investigated using all-atom reactive equilibrium and non-equilibrium molecular-dynamics analyses. The purpose of this paper is to reveal the beneficial shockwave dispersion/attenuation effects offered by the chemical reaction, direct simulations of a fully supported single planar shockwave propagating through the reactive mixture were carried out, and the structure of the shock front examined as a function of the extent of the chemical reaction (i.e. as a function of the strength of the incident shockwave). The results obtained clearly revealed that chemical reactions give rise to considerable broadening of the shockwave front. In the present work, the effect of chemical reactions and the structure of the shockwaves are investigated at the continuum level.

Specifically, the problem of the (conserved) linear-momentum accompanying the interaction of an incident shockwave with the protective-structure/protected-structure material interface has been investigated, within the steady-wave/structured-shock computational framework, in order to demonstrate and quantify an increase in the time period over which the momentum is transferred and a reduction in the peak loading experienced by the protected structure, both brought about by the occurrence of the chemical reaction (within the protective structure).

The results obtained clearly revealed the beneficial shock-mitigation effects offered by a protective structure capable of undergoing a chemical reaction under shock-loading conditions.

To the authors’ knowledge, the present manuscript is the first report dealing with a continuum-level analysis of the blast-mitigation potential of chemical reactions.

Commences with a review of the differences between consumer and business markets, and then proceeds to review the characteristics of the on‐line search services that have changed in order to facilitate the transition to end‐user services. Products have been significantly re‐designed to meet the needs of the end‐users. Interfaces have been improved, a range of different distribution channels are available, and products and services have been clustered. However, pricing strategies remain reminiscent of business markets. Online search services can not be regarded as retailers, but in offering products that are attractive to the end‐user are engaged in tactics that will push their products through the distribution chain.

Insight has grown that for an organization to learn and change successfully, forgetting and unlearning are required. The purpose of this paper is to summarize the relevant existing body of empirical research on forgetting and unlearning, to encourage research using a greater variety of methods and to contribute to a more complementary body of empirical work by using designs and instruments with a stronger reference to previous studies.

As the number of theoretical papers clearly exceeds the number of empirical papers, the present paper deals with the main insights based on the empirical state of research on unlearning and forgetting. So far, these empirical results have shown relationships between unlearning and other organizational outcomes such as innovation on an organizational level, but many of the other proposed relationships have not been investigated. The authors presents suggestion to apply a larger variety of qualitative, quantitative and mixed methods in organizational research.

Unlearning and forgetting research can benefit both from more diverse theoretical questions addressed in research and from a more complementary body of empirical work that applies methods, designs and instruments that refer to previous research designs and results. To understand and manage unlearning and forgetting, empirical work should relate to and expand upon previous empirical work to form a more coherent understanding of empirical results.

The paper presents a variety of research designs and methods that can be applied within the research context of understanding the nature of organizational forgetting and unlearning. Additionally, it illustrates the potential for different methods, such as experience sampling methods, which capture the temporal aspects of forgetting and unlearning.

In the Spring 1992 issue of Reference Services Review, Douglas Ernest, Joan Beam, and Jennifer Monath noted that “Telephone directories have been an integral part of most public and academic libraries for nearly a century. Telephone directories represent an anomaly among library collections; known to virtually all users, they nevertheless often go unrecognized when librarians discuss reference sources.” After the break‐up of the AT&T telephone monopoly in 1984, the process of acquiring telephone directories became more difficult and expensive. Seven regional holding companies, called the “Baby Bells,” were created to provide competition for the equipment and services that were once dominated by “Ma Bell.” The regional Bell companies began to charge each other for directories; as a result, the regional telephone companies had to pass on the expense to customers. It is still common for a regional Bell to provide libraries with directories of in‐state white pages, but to charge for areas outside the state, separate yellow pages within the state, and independently published telephone directories. Telephone directories, once provided free of charge to libraries to reduce the workload of operators, are now in competition with the fee‐based service of directory assistance.

Because of the increasing importance of access over ownership, the purpose of this paper is to propose a service ecosystem perspective to help managers navigate hypercompetition. With the rise of cloud-based services and the ongoing recovery from the COVID-19 pandemic, the global economy has shifted toward hypercompetition, a state characterized by organizational advantages that are rapidly created and then destroyed by intense competitive moves. Because advantages are quickly eroded, organizations must be aggressive in the number of actions they take and the speed with which they execute these actions. The service ecosystem perspective focuses on relationships that allow organizations to jointly adjust to one another and to their environment.

This paper first reviews traditional strategies for navigating hypercompetition. Then, it presents an explanation of the service ecosystem perspective. Finally, the three north stars and media examples are provided.

The service ecosystem perspective asserts “north stars” that can guide managerial decision-making in hypercompetitive environments. These north stars are: cultivate system norms, facilitate feedback loops and embrace servitization.

In today’s world, organizations are increasingly seeking access to resources instead of ownership of them. The proposed approach suggests that, rather than an organization owning the resources it needs to achieve advantages, organizations are increasingly relying on accessing resources by coordinating with other organizations to draw upon the resource(s) as needed, without incurring the additional burdens of ownership. Examples from the media industry are used to illustrate the three north stars of the service ecosystems perspective.

Although endorsers are thought to be highly effective when they match-up with a product, the current understanding of endorser match-up offers little insight for distinctions between equally attractive and trustworthy endorsers who have equivalent expertise in the product category, yet still diverge in their performance. Therefore, the main purpose of this research is to understand how a match between social judgments (i.e. warmth vs competence) of a celebrity endorser and specific advertising appeals (i.e. symbolic vs utilitarian) can improve consumer responses to an endorsement.

A preliminary study empirically distinguishes perceptions of warmth and competence from prevailing celebrity endorser evaluative criteria. Then, the authors conduct multiple 2 (warmth vs competence) × 2 (symbolic vs utilitarian) between-subjects experiments to demonstrate the effect of matching social judgments and advertising messaging, across celebrity genders (i.e. male and female), forms of marketing communications (i.e. print ads and interactive online ads) and types of brands (i.e. well-established and new/unknown).

The findings demonstrate that matching celebrity endorser social judgments with the appropriate type of advertising messaging positively influences consumer response to the brand for both male and female endorsers. Additionally, despite a commonly held belief that celebrity endorsements are more effective at changing attitudes than actual behaviors, for interactive online ads, the authors find that the match strategy can motivate consumer response through two different pathways. For well-established brands, the match improves overall brand response predominately through cognitive and behavioral mechanisms. Alternatively, for new or unknown brands, the match initially impacts affective responses, which are subsequently related to consumers shopping a brand’s product category, rating a brand higher in customer recommendations, choosing a brand’s products over top competitors and paying more for the brand’s offerings.

The main contribution of this research is the demonstrated support for an alternative and effective application of the match-up hypothesis, based on a fit between the endorser and the advertising messaging itself.
