IP reputation systems, which filter e‐mail based on the sender's IP address, are located at the perimeter – before the messages reach the mail server's anti‐spam filters. To increase IP reputation system efficacy and overcome the shortcomings of individual IP‐based filtering, recent studies have suggested exploiting the properties of IP clusters, such as those of Autonomous Systems (AS). Cluster‐based techniques can enhance accuracy and reduce false negative rates. However, clusters generally contain enormous amounts of IP addresses, which hinder cluster‐based systems from reaching their full spam filtering potential. The purpose of this paper is exploitation of social network metrics to obtain a more granular, i.e. sub‐divided, view of cluster‐based reputation, and thus enhance spam filtering accuracy.

The authors examined the performance of various social network metrics, including nodal degree, betweenness centrality, closeness centrality and valued graphs, to find an optimal element that enhances IP reputation prediction in AS clusters.

It was found that all measures contributed to prediction, yet the best predictor of spam reputation was the out‐degree metric, which showed a strong positive correlation with spam reputation prediction. This implies that more granular information can increase the accuracy of IP reputation prediction in AS clusters.

Used in conjunction with other technologies, the granular cluster‐based reputation system can be a valuable addition to commercial and open‐source spam filtering systems, or to standalone DNS‐based blacklists.

The authors' approach can promote mitigation of larger spam volumes at the perimeter, save bandwidth, and conserve valuable system resources.

In this study, we investigate how capability in managing intellectual property may be treated as a type of “dynamic capability,” and we seek to understand how, when it is linked to the new technology development capability of a complex technological organization, these two types of dynamic capabilities may coevolve.

We conducted a longitudinal empirical case study of Airbus, incorporating an abductive research methodology that required investigating theory and empirical data concurrently and iteratively. The data, ranging over a period of two decades from 2000 to 2021, was collected from four different sources, including interviews, internal company documents, publicly available information and patent data.

Our main findings are that the capabilities and roles of the Intellectual Property function in Airbus and their interaction with the company's Technology function have indeed influenced the overall innovation strategy of the organization, and that three coevolutionary phases may be identified in the interactive development of the two functions.

Our investigation into how new technology development and intellectual property (IP) management capabilities coevolve within complex technological organizations, exemplified by Airbus, provides significant theoretical and practical implications. Theoretically, it enhances understanding of capability co-development dynamics in complex organizations, particularly in strategic IP management. Practically, it suggests aligning IP strategy with overall corporate objectives and optimizing organizational structures to promote collaboration and efficiency across IP and technology teams. This alignment may foster innovation, maximize the value of intellectual assets and strengthen collaborations, positioning organizations for long-term success in competitive landscapes.

This study makes a fresh contribution to the innovation studies literature by showing how if intellectual property management is treated as a core function of a complex technological organization – rather than simply as a vehicle for protecting new inventions and products after the fact or simply as a constituent part of the organization's legal function – it may contribute proactively to the organization's technological innovation performance. We also address the current gap in the academic literature for a clear understanding of the processes by which different function-specific dynamic capabilities may coevolve in a complex organization operating as part of a dynamic and complex adaptive system.

Co-innovation networks face the important challenge of cultivating collective innovation outcomes while also preserving the interests of individual contributors. Addressing this challenge requires first understanding and then managing individuals’ perception of co-innovation risks. The purpose of this paper is to provide a meaningful approach to addressing co-innovation risks using a valid and reliable model to assess actors’ perception of risk and examine its effect on actor co-innovation behavior.

The construct of co-innovation risk from the actor’s perspective was conceptualized based on a case study of a co-innovation network. The measurement items underwent a pilot study and a field study to establish the necessary reliability and validity. This paper also empirically assesses a nomological network that illustrates the effect of risk on co-innovation behavior with a moderating effect of prior experience.

Co-innovation actors perceived four different individual risks: time, social, intellectual property right, and financial. The empirical results from the field study demonstrate a high degree of confidence in both translation validity and criterion-related validity. Negative effects of perceived co-innovation risk on actors’ continuous intention to ideate, collaborate, and communicate in co-innovation were evident, but prior experience moderated these relationships.

Drawing from co-innovation and individual risk literature, this study develops and validates a general instrument to measure co-innovation risk from the actors’ perspective. The result is a reliable and parsimonious instrument with 15 items, which contributes significantly to future empirical investigations of co-innovation behavior on virtual platforms.

In the UK there is now recognition that university research can be a valuable source of intellectual property (IP) on which new wealth-creating industries can be based. This recognition has led to a debate about, how best the IP can be developed, captured and transferred to the commercial world. The Lambert Report, published in December 2003 made many useful observations about the relative merits of licensing or spin-out models of technology commercialisation and the roles of university-based Technology Transfer Offices (TTOs) in stimulating or supporting these processes (Lambert Review of Business-University Collaboration, 2003).

Scholars of business, economics, and law have long recognized that rights to intellectual property (IP) intimately shape innovative activity and the pursuit of profits. More than 60 years ago, Michal Polanyi voiced the following concerns about awarding property rights to creations of the “intellect”:The law…aims at a purpose which cannot be rationally achieved. It tries to parcel up a stream of creative thought into a series of distinct claims, each of which is to constitute the basis of a separately owned monopoly. But the growth of human knowledge cannot be divided into such sharply circumscribed phases. Ideas usually develop gradually by shades of emphasis, and even when, from time to time, sparks of discovery flare up and suddenly reveal a new understanding, it usually appears that the new idea has been at least partly foreshadowed in previous speculations. (Polanyi, 1944, pp. 70–71)

The purpose of this paper is to explore the inter-organisational dynamics, in terms of the triggers to spin-off formation and the genealogical inheritance of spin-offs, between a parent characterised by an adverse event and the spin-offs that emerge. The study focusses on the nature of the triggering event, exploring the heterogeneous nature of the processes by which some spin-offs are formed to exploit new opportunities created unexpectedly by an adverse event, and on the genealogical inheritance that forms the pre-entry experience of the founder.

A case study based on interview data with founders of spin-offs, supplemented with interviews with managers and industry experts, and with secondary data sources. The case study is of the spin-offs from a successful firm, Élan Corporation, reported to be the world’s 20th largest drug firm in 2002, that experienced an adverse event in 2002. The Élan case offers the opportunity to focus exclusively on what Buenstorf (2009) refers to as necessity spin-offs. Prior to collecting data it was necessary to identify the population of spin-offs from Élan.

This study extends existing research by identifying “opportunistic spin-offs”: spin-offs that occur in the wake of an adverse event where the entrepreneur exploits an unexpected opportunity to engage in entrepreneurship but does not feel compelled to establish the spin-off. These spin-offs are characterised by “unexpected opportunities”, “opportunistic acquisition of assets” and, perhaps reflecting the seniority and experience of those involved, “alternative employment opportunities”.

Understanding the process of spin-off formation is important because it provides insight into how and why individuals initiate new ventures. Spin-offs are an important source of new firms and an important mechanism in the process of industry evolution. The study contributes to the literature on spin-offs by providing evidence of the heterogeneous nature of spin-offs that occur in the aftermath of an adverse event, leading to the classification of some spin-offs as “opportunistic spin-offs”. The study contributes to the entrepreneurship literature by demonstrating that an important trigger for venture creation is unexpected changes in an individual’s employment circumstances.

Through a critical review of the impact of luxury international business, this study aims to contribute to an understanding of business activities that depend on an unequal distribution of income and wealth.

Drawing on a wide range of academic and practitioner literature, this study adopts a critical luxury studies approach to provide an assessment of the economic and social impact of luxury international business.

Luxury is an increasingly important sector of the economy, which contributes to the welfare of increasing numbers of people across the world. Alongside its dependence on an unequal distribution of income and wealth and the negative aspects to which this gives rise, luxury business generates significant benefits to the economy and society through promoting economic growth, innovation, cultural enrichment, improved quality of the built environment and environmentally sustainable business practices. Nevertheless, an appropriate level of regulation and taxation on the excesses of contemporary luxury consumption could improve the welfare of all. Hence, luxury international business warrants investigation by critical scholars who recognize the complexity of the benefits and dark sides arising from luxury.

This study draws on an extensive review of academic and practitioner literature. However, primary research is required to investigate further the key issues identified.

Through an exploration of the impact of the production and consumption of luxury, this study reveals how luxury businesses serving the super-rich can contribute to the welfare of society whilst also giving rise to negative outcomes.

By adopting a critical luxury studies approach, this study offers an original contribution to the field of international business and introduces avenues for future critical international business research.

The impact of cyberattacks all over the world has been increasing at a constant rate every year. Performing exploratory analysis helps organizations to identify, manage and safeguard the information that could be vulnerable to cyber-attacks. It encourages to the creation of a plan for security controls that can help to protect data and keep constant tabs on threats and monitor their organization’s networks for any breaches.

The purpose of this experimental study is to state the use of data science in analyzing data and to provide a more detailed view of the most common cybersecurity attacks, what are the most accessed logical ports, visible patterns, as well as the trends and occurrence of attacks. The data to be processed has been obtained by aggregating data provided by a company’s technology department, which includes network flow data produced by nine different types of attacks within every day user activities. This could be insightful for many companies to measure the damage caused by these breaches but also gives a foundation for future comparisons and serves as a basis for proactive measures within industry and organizations.

The most common cybersecurity attacks, most accessed logical ports and their visible patterns were found in the acquired data set. The strategies, which attackers have used with respect to time, type of attacks, specific ports, IP addresses and their relationships have been determined. The statistical hypothesis was also performed to check whether attackers were confined to perform random attacks or to any specific machines with some pattern.

Policies can be suggested such that if an attack is conducted on a specific machine, which can be prevented by identifying the machine, ports and duration of the attacks on which the attacker is targeting and to formulate such policies that the organization should follow to tackle these targeted attacks in the future.

The purpose of this paper is to outline concepts that explore and extend the significance of public relations as a relationship management discipline.

The paper postulates practice through which value is created to meet organisational objectives from the known or latent potential of tangible and intangible assets. In doing so, a definition and early research findings into the nature of relationships is put forwards and a definition of organisations as the nexus of relationships is proposed. The differentiation between organisational and interpersonal relationships is explored through a concept that organisations' tangible and intangible tokens are limited by a concept of materiality in a cultural setting.

The paper posits that material value is released through a process of relationship change and a public relations practice of relationship management is put forward as a management discipline that can create value when the process of relationship management acting on material tokens is deployed.

The paper explores how public relations is an agent for changing the value of organisations.

It is 10 years since the International Integrated Reporting Council (IIRC) was founded and the development of the IIRC Framework has been adopted by thousands of organisations. This paper aims to provide empirical evidence on the motivation for the preparation of integrated reports from a diffusion of innovation (DOI) perspective.

Three case study organisations operating in distinct industry sectors are investigated to ascertain the motivation for the adoption of integrated reporting. DOI theory was adopted as the theoretical lens to guide the research design. An interpretative approach is used to ascertain common themes from an analysis of semi-structured interview transcripts of senior managers and directors.

The findings from these case studies support the main tenets of DOIs theory. The evidence suggests that senior executive leadership plays a significant role in commencing the integrated reporting “journey”. This study finds evidence of DOI characteristics, such as relative advantage, compatibility and observability with respect to the objectives of senior managers. The main motivations for the production of the integrated report were to demonstrate leadership and innovation to stakeholders, overcome the perceived inadequacies of the disclosures required for traditional annual reports, to enhance transparency and to satisfy the changing demands of investors and other stakeholders.

This project captures the perceptions and views of preparers of the integrated report rather than its users. In addition, only three case study sites were investigated, therefore, generalisations would be spurious.

Other organisations yet to consider the production of integrated reports or to re-assess their stakeholder relationships, could use these findings to plan for their own future reporting obligations.

The organisations investigated were a superannuation fund, a multinational company and a charity. All are recognised leaders in their respective industries.
