A Survey on Forensics and Compliance Auditing for Critical Infrastructure Protection
The broadening dependency and reliance that modern societies have on essential services
provided by Critical Infrastructures is increasing the relevance of their trustworthiness. However, Critical
Infrastructures are attractive targets for cyberattacks, due to the potential for considerable impact, not just
at the economic level but also in terms of physical damage and even loss of human life. Complementing
traditional security mechanisms, forensics and compliance audit processes play an important role in ensuring
Critical Infrastructure trustworthiness. Compliance auditing contributes to checking if security measures are
in place and compliant with standards and internal policies. Forensics assist the investigation of past security
incidents. Since these two areas significantly overlap, in terms of data sources, tools and techniques, they can
be merged into unified Forensics and Compliance Auditing (FCA) frameworks. In this paper, we survey the
latest developments, methodologies, challenges, and solutions addressing forensics and compliance auditing
in the scope of Critical Infrastructure Protection. This survey focuses on relevant contributions, capable of
tackling the requirements imposed by massively distributed and complex Industrial Automation and Control
Systems, in terms of handling large volumes of heterogeneous data (that can be noisy, ambiguous, and
redundant) for analytic purposes, with adequate performance and reliability. The achieved results produced
a taxonomy in the field of FCA whose key categories denote the relevant topics in the literature. Also, the
collected knowledge resulted in the establishment of a reference FCA architecture, proposed as a generic
template for a converged platform. These results are intended to guide future research on forensics and
compliance auditing for Critical Infrastructure Protection.info:eu-repo/semantics/publishedVersio

The impact of enterprise social networking on knowledge sharing between academic staff in higher education
This thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University LondonHigher education institutions have always considered knowledge sharing critical for research excellence and finding proper methods for sharing knowledge across academic staff has therefore been a major issue for universities and knowledge management research. Recent evidence shows that many universities have embraced enterprise social networking tools to improve communication, relationships, partnerships, and knowledge sharing. To date, there is little understanding of the critical factors for online knowledge sharing behaviour between academic staff, and the impact of these factors on work benefits for academic staff which differ between consumptive users and contributive users in higher education. This study employed the extended unified theory of acceptance and use of technology (UTAUT) to examine factors affecting knowledge sharing about the consumptive use and contributive use of enterprise social network (ESN) behaviour. The study adopts a critical realism philosophical approach and employed a grounded theory mixed methods. The conceptual model was validated through structural equation modelling based on an online survey of 254 academic staff using enterprise social networking as a part of their work in the United Kingdom. The findings have significant theoretical and practical implications for researchers and policy makers. The research has developed a cohesive ESN use model by extending and modifying the unified theory of acceptance and use of technology. The findings indicate significant differences around factors affecting consumptive and contributive usage patterns within ESNs. Due to advances in communication technologies, this research argues that a previous model suggested by Venkatesh et al. (2003) is no longer fit for purpose and the new communication tools can lead to improved knowledge in higher education. This research also makes valuable contributions to universities from a managerial viewpoint, suggesting that universities could help their scholars find a more comprehensive range of funding sources matching scholars' ideas
“So what if ChatGPT wrote it?” Multidisciplinary perspectives on opportunities, challenges and implications of generative conversational AI for research, practice and policy
Transformative artificially intelligent tools, such as ChatGPT, designed to generate sophisticated text indistinguishable from that produced by a human, are applicable across a wide range of contexts. The technology presents opportunities as well as, often ethical and legal, challenges, and has the potential for both positive and negative impacts for organisations, society, and individuals. Offering multi-disciplinary insight into some of these, this article brings together 43 contributions from experts in fields such as computer science, marketing, information systems, education, policy, hospitality and tourism, management, publishing, and nursing. The contributors acknowledge ChatGPT’s capabilities to enhance productivity and suggest that it is likely to offer significant gains in the banking, hospitality and tourism, and information technology industries, and enhance business activities, such as management and marketing. Nevertheless, they also consider its limitations, disruptions to practices, threats to privacy and security, and consequences of biases, misuse, and misinformation. However, opinion is split on whether ChatGPT’s use should be restricted or legislated. Drawing on these contributions, the article identifies questions requiring further research across three thematic areas: knowledge, transparency, and ethics; digital transformation of organisations and societies; and teaching, learning, and scholarly research. The avenues for further research include: identifying skills, resources, and capabilities needed to handle generative AI; examining biases of generative AI attributable to training datasets and processes; exploring business and societal contexts best suited for generative AI implementation; determining optimal combinations of human and generative AI for various tasks; identifying ways to assess accuracy of text produced by generative AI; and uncovering the ethical and legal issues in using generative AI across different contexts
Business Functions Capabilities and Small and Medium Enterprises’ Internationalization
Ineffective global expansion can adversely affect small and medium enterprises (SMEs) business outcomes. Business leaders are concerned with developing effective global expansion strategies to penetrate potential international markets, thus enhancing sustainability. Grounded in the business management systems theory, the purpose of this qualitative multi-case study was to explore strategies that leaders of Sub-Saharan Africa manufacturing SMEs use for global expansion. The participants were five manufacturing value-adding SME leaders participating in export markets. Using Yin’s five steps data analysis process, six themes emerged: (a) enterprise characterization, (b) understanding the enterprise’s product, (c) intra-enterprise factor-based strategies for export participation, (d) the enterprise’s external factor-based strategies for successful export venture, (e) global expansion strategies, and (f) serendipitous findings. A key recommendation for SME leaders is to analyze the critical components of their products and prepare to adjust them to the demand dimensions of the target market. The implications for positive social change include the potential to increase the enterprise’s wealth, increase employment, reduce poverty for all value chain participants, and growth in gross domestic product

The impact of employees' working relations in creating and retaining trust: the case of the Bahrain Olympic Committee
Introduction: This thesis investigates the impact of employees’ working relations in creating, maintaining and retaining trust in the Bahrain Olympic Committee (BOC).
Aim: The main aim of this thesis is to determine how the three groups of Organisational Trust variables, namely Social System Elements (SSE), Factors of Trustworthiness (FoT) and Third-Party Gossip (TPG), affect employees’ Organisational Trust (OTR) in the BOC and promote Organisational Citizenship Behaviour (OCB). To answer this main aim, a conceptual framework was created that focused on exploring the following research aims: (1) the interrelationship between SSE and FoT, (2) the effect of SSE on OTR, (3) the impact of TPG on OTR and (4) the effect of OTR on overall OCB.
Methodology: The study uses a mixed-method case study research style that included in-depth semi-structured interviews with 17 managers, an online questionnaire survey with 320 employees of the BOC and an analysis of the BOC’s Annual Reports from 2015 to 2018.
Results: The qualitative and quantitative findings indicate, firstly, that there is a significant interrelationship between SSE and FoT, establishing that SSE’s perception of organisational justice (OJ), including that FoTs benevolence and integrity as the most important factors in yielding employees’ trust in the BOC. Secondly, it has been established that SSEs have significant direct and indirect effects on OTR. Thirdly, negative and positive TPG concurrently occurred in the BOC and the prevalence of negative TPG poses more impact on OTR. Finally, this study’s findings demonstrated OTR’s effect in generating OCB, including that Civic Virtue was rated as the most preferred of the five OCB themes; this indicates the managers’ and the employees’ strong emotional attachment and support of the activities taking place at the BOC.
Contributions: Overall, this thesis substantially contributes to OTR literature, particularly in the context of the Middle East. It also proposes several insightful recommendations for future research and practical implications for practitioners in the field of Organisational Trust
Boundary Spanner Corruption in Business Relationships
Boundary spanner corruption—voluntary collaborative behaviour between individuals representing different organisations that violates their organisations’ norms—is a serious problem in business relationships. Drawing on insights from the literatures on general corruption perspectives, the dark side of business relationships and deviance in sales and service organisations, this dissertation identifies boundary spanner corruption as a potential dark side complication inherent in close business relationships It builds research questions from these literature streams and proposes a research structure based upon commonly used methods in corruption research to address this new concept. In the first study, using an exploratory survey of boundary spanner practitioners, the dissertation finds that the nature of boundary spanner corruption is broad and encompasses severe and non-severe types. The survey also finds that these deviance types are prevalent in a widespread of geographies and industries. This prevalence is particularly noticeable for less-severe corruption types, which may be an under-researched phenomenon in general corruption research. The consequences of boundary spanner corruption can be serious for both individuals and organisations. Indeed, even less-severe types can generate long-term negative consequences. A second interview-based study found that multi-level trust factors could also motivate the emergence of boundary spanner corruption. This was integrated into a theoretical model that illustrates how trust at the interpersonal, intraorganisational, and interorganisational levels enables corrupt behaviours by allowing deviance-inducing factors stemming from the task environment or from the individual boundary spanner to manifest in boundary spanner corruption. Interpersonal trust between representatives of different organisations, interorganisational trust between these organisations, and intraorganisational agency trust of management in their representatives foster the development of a boundary-spanning social cocoon—a mechanism that can inculcate deviant norms leading to corrupt behaviour. This conceptualisation and model of boundary spanner corruption highlights intriguing directions for future research to support practitioners engaged in a difficult problem in business relationships
Antecedents of customer loyalty in the manufacturing industry
This thesis concerns the study of customer loyalty and its antecedents in the UK
manufacturing sector. It adopts a critical realist perspective to the study of customer loyalty,
locating the concept in the relationship marketing and social psychology literatures. The
findings generated by the literature review and the results of an exploratory qualitative study
leads to the development of a conceptual framework in which functional, social and
emotional relationship value, customer satisfaction, and moderator variable, relationship age,
are believed to influence the level of customer loyalty in the manufacturing industry.
The conceptual framework is tested empirically using a quantitative survey design in the
context of the UK manufacturing industry. Data is analysed through application of the partial
least squares (PLS) structural equation modelling technique.
From a theoretical perspective, the study makes a number of valuable contributions to the
relationship marketing literature. The study confirms the importance of social and emotional
relationship value aspects on customer satisfaction and loyalty outcomes in the
manufacturing industry. The findings offer a new theoretical perspective of the role social and
emotional value play in creating loyal customers and the role emotional value performs in
buyer’s feelings of satisfaction in the B2B domain. The findings also suggest that customer
satisfaction acts as a partial mediator in the relationship between customer value and
customer loyalty. Moreover, a new theoretical concept of emotional value featuring frustration
and human touch in addition to interpersonal relationships is also evidenced from the
research results. Furthermore, the study also shows that the theory of consumption values
can be applied to the B2B manufacturing domain.
The results propose that behavioural loyalty can be expressed through customer satisfaction,
and functional and emotional elements of relationship value. Whereas, attitudinal loyalty can
be conveyed by customer satisfaction, and functional and social components of relationship
value. These relationships are in turn also partially mediated through customer satisfaction.
The results also indicate that all three dimensions of functional, social and emotional value
influence customer satisfaction outcomes.
Overall, the study provides recommendations on how to maximise customer loyalty through
strategic combinations of relationship value. It also provides guidance on how to improve
customer satisfaction through different elements of relationship value in the manufacturing
industry. From a practical viewpoint, the research study findings offer suppliers important
guidelines and a toolkit for establishing, developing, and maintaining successful relationships
with their customers in the manufacturing industry
An empirical investigation of the relationship between integration, dynamic capabilities and performance in supply chains
This research aimed to develop an empirical understanding of the relationships between integration,
dynamic capabilities and performance in the supply chain domain, based on which, two conceptual
frameworks were constructed to advance the field. The core motivation for the research was that, at
the stage of writing the thesis, the combined relationship between the three concepts had not yet
been examined, although their interrelationships have been studied individually.
To achieve this aim, deductive and inductive reasoning logics were utilised to guide the qualitative
study, which was undertaken via multiple case studies to investigate lines of enquiry that would
address the research questions formulated. This is consistent with the author’s philosophical
adoption of the ontology of relativism and the epistemology of constructionism, which was considered
appropriate to address the research questions. Empirical data and evidence were collected, and
various triangulation techniques were employed to ensure their credibility. Some key features of
grounded theory coding techniques were drawn upon for data coding and analysis, generating two
levels of findings. These revealed that whilst integration and dynamic capabilities were crucial in
improving performance, the performance also informed the former. This reflects a cyclical and
iterative approach rather than one purely based on linearity. Adopting a holistic approach towards
the relationship was key in producing complementary strategies that can deliver sustainable supply
chain performance.
The research makes theoretical, methodological and practical contributions to the field of supply
chain management. The theoretical contribution includes the development of two emerging
conceptual frameworks at the micro and macro levels. The former provides greater specificity, as it
allows meta-analytic evaluation of the three concepts and their dimensions, providing a detailed
insight into their correlations. The latter gives a holistic view of their relationships and how they are
connected, reflecting a middle-range theory that bridges theory and practice. The methodological
contribution lies in presenting models that address gaps associated with the inconsistent use of
terminologies in philosophical assumptions, and lack of rigor in deploying case study research
methods. In terms of its practical contribution, this research offers insights that practitioners could
adopt to enhance their performance. They can do so without necessarily having to forgo certain
desired outcomes using targeted integrative strategies and drawing on their dynamic capabilities
Essays on Manufacturers’ IT Capabilities for Digital Servitization
Over the last decades, studies have found that transformational drivers affect how firms innovate their business models (Chesbrough, 2010; Massa et al., 2016). In markets in which physical products become commodities, the servitization of business models is a transformational driver for firms (Wise & Baumgartner, 1999). For its part, digitalization increases the potential to reshape business models through novel use cases of technology (Yoo et al., 2010). Recently, digitalization was found to extend the opportunities from servitization through digital technologies as digital servitization (Paschou et al., 2020). Digital servitization describes a firm’s shift from product-centric offerings to service-centric offerings with the help of novel IT assets (Naik et al., 2020). The manufacturing industry provides promising examples of firms with portfolios of physical offerings that might undergo such a transformational shift (Baines et al., 2017).
So far, digital servitization research focuses primarily on four topics: re-defining the notion of servitization in the context of digitalization, identifying digital servitization value drivers, linking the transformation to specific technologies, and deriving how novel service offerings arise (Paschou et al., 2020; Zhou & Song, 2021).
Despite the breadth of digital servitization research, how firms can shift to service-centric offerings remains unclear (Kohtamäki et al., 2019). Specifically, research lacks studies on the prerequisites and mechanisms that link theory with evidence on achieving IT-enabled service innovation (Paschou et al., 2020). Further, how firms must organize to build and operate IT-enabled services around these technologies remains unclear (Paschou et al., 2020). In a recent report on the manufacturing industry, practitioners confirm these gaps and associate them with a lack of managerial and technical knowledge (Illner et al., 2020).
A theoretical lens that helps to address these shortcomings is the knowledge-based theory. It suggests that knowledge is the primary rationale, so that a firm benefits from its assets (Grant, 1996b; Nonaka, 1994). The knowledge-based theory understands a capability as a directed application of knowledge in a firm’s activities (Grant, 1996b; Nonaka, 1994). In the context of digitalization, firms require IT capabilities based on knowledge of how to capitalize on IT assets (Lee et al., 2015). Digital servitization research finds that IT capabilities are critical for identifying, adapting, and exploiting IT-enabled service innovations (Johansson et al., 2019). Still, little extant research informs firms that undergo digital servitization about which IT capabilities can help to strengthen their competitive advantage (Coreynen et al., 2017).
Even though IT capabilities may be necessary for success in innovating IT-enabled services, the required knowledge needs to be disseminated effectively throughout an organization (Foss et al., 2014; Grant, 1996a; Nonaka, 1994). The organizational control theory offers a theoretical perspective about knowledge dissemination mechanisms, which can be horizontal or vertical (Ouchi, 1979). Horizontal knowledge dissemination mechanisms depend on codifying processes in rules or measuring process outputs through indicators, while the locus of exerting these rules and indicators determines the vertical knowledge dissemination. The IT innovation and IT governance literature refers to these knowledge dissemination mechanisms as formalization of IT activities and centralization of IT decision-making (Weill, 2004; Winkler & Brown, 2013; Zmud, 1982). However, how to orchestrate knowledge, particularly for IT capabilities, in firms that undergo digital servitization is not yet clear (Kohtamäki et al., 2019; Münch et al., 2022; Sjödin et al., 2020).
Against this background, this dissertation addresses how manufacturers organize their IT capabilities while encountering the transformational drivers of digital servitization by answering the following overarching research question:
