Architecture of participation : the realization of the Semantic Web, and Internet OS

Thesis (S.M.)--Massachusetts Institute of Technology, System Design and Management Program, February 2008.Includes bibliographical references (p. 65-68).The Internet and World Wide Web (WWW) is becoming an integral part of our daily life and touching every part of the society around the world including both well-developed and developing countries. The simple technology and genuine intention of the original WWW, which is to help researchers share and exchange information and data across incompatible platforms and systems, have evolved into something larger and beyond what one could conceive. While WWW has reached the critical mass, many limitations are uncovered. To address the limitations, the development of its extension, the Semantic Web, has been underway for more than five years by the inventor of WWW, Tim Berners-Lee, and the technical community. Yet, no significant impact has been made. Its awareness by the public is surprisingly and unfortunately low. This thesis will review the development effort of the Semantic Web, examine its progress which appears lagging compared to WWW, and propose a promising business model to accelerate its adoption path.by Shelley Lau.S.M

Conceptualisation and development of the admin-avatar taxonomy : antecedents, attitudinal and behavioural consequences

Academics and practitioners have increasingly acknowledged the significance of the consumer–brand relationship in both traditional and online contexts. However, the impersonal nature of the online environment is considered to be a hindrance in the development of the brand–consumer relationship. The literature suggests that strong relationship outcomes depend on successful relationship marketing tactics. Admin-avatar concept is a new concept -firstly emerged in this research- which can be used as a technological and marketing tactic. Admin-avatar can embody consumer-facing employees and mimic their real-life roles on companies’ websites, thereby playing a key role in enhancing the relationships between consumers and brands in the online environment. Despite the importance of this technology, very little attention has been paid to the investigation of the admin-avatar concept from a marketing perspective. Following a systematic review of the literature found in 10 major electronic databases and published between 1993 and 2013, significant gaps in literature were identified. Specifically, this research examines the nature of the admin-avatar concept, including its main characteristics, dimensions, and conditions as well as the attitudinal and behavioural consequences of admin-avatar users.Adopting the mixed methods design, a taxonomy was developed from interviews (qualitative phase) which laid the foundation for the development of the admin-avatar framework. Spiggle’s (1994) framework was adopted for the qualitative data analysis. A conceptual framework was developed and built on the theoretical foundations of reasoned action theory (Fishbein & Ajzen, 1975). The admin-avatar framework was empirically tested through a series of lab-based experiments (quantitative phase). Following a confirmatory factor analysis (CFA) was carried out to purify the scales, determine the dimensionality of the constructs and support their convergent and discriminant validity. The context used for this study was the university admissions admin-avatar. propositions were tested using repeated measures (first experimental deign study), factorial design (second experimental deign study) and serial mediation techniques for both experimental studies. The results mostly support the taxonomy developed from the qualitative phase.This thesis contributes to the new technology in marketing and practice, specifically by: (1) providing a clear and comprehensive definition of the admin-avatar concept, (2) developing a comprehensive taxonomy of admin-avatar that enriches the area of new technology in marketing by the further investigations by applying the taxonomy to other contexts (e.g., schools, banks, retails and other commercial companies), and (3) confirming the notion that the addition of an admin-avatar will transform the consumer attitude towards the website and the brand. Furthermore, the addition of an admin-avatar will prompt consumers to engage in voluntary behaviours such as saying positive things about the organisation/brand (word of mouth) and recommending the brand and its products to other potential consumers (recommendation). In other words, adding the admin-avatar on the brand website will significantly change the attitudes of brand’s consumers. These positive attitudes will encourage consumers to do voluntary behviours for the brand. From a practical perspective, these findings offer practitioners a clearer and richer understanding of the admin-avatar, facilitating appropriate designs for admin-avatar(s). The findings of this research also give practitioners clear insights into the main advantages of the admin-avatar, such as the degree of its convenience (e.g., quickness and effortless), hedonism (excitement) and attractiveness

Open design and medical products

This research details the use of Open Design to enable participation in the conceptualisation, design and development of medical products for those who are excluded by their chronic health condition. The research was directed according to the Action Research methodology outlined by Checkland & Holwell (1998); Action Research being highlighted by Archer (1995) as a method compatible for practice-led design research. Open design directed the design practice, which consisted of a long case study spanning 18 months from February 2012, through to July 2013. This case study, dubbed AIR involved the creation of a bespoke online social network, recruitment of people living with cystic fibrosis, and the facilitation of collaborative design work resulting in prototype medical devices based on the lived experience of the participants. The work involves research into design within health as the context for this research. In order to place design in this wider context, it has been tempting to adopt the mantle Evidence Based Design Evans, 2010) – however in this research the position of design as phronesis, in a similar manner to health practice (Montgomery, 2005) is adopted. This allows for an alignment of the work done in both fields, without the problematic associations with an evidence hierarchy (Gaver & Bowers, 2012; Holmes, Murray, Perron, & Rail, 2006). The contribution to knowledge is an Open Medical Products Methodology, consisting of the artefacts supporting the evidence of the methodology’s ability to foster genuine participation amongst those who are excluded from traditional participatory design. The artefacts constituting this submission are this thesis, the reflective log kept during the research (Appendix A on page 135), the prototypes from the collaborative research (Appendix B on page 212), and the online social network that contained the work (AIR1 ). The Open Medical Products Methodology is expected to be of interest primarily to designers of medical products, design management and policymakers- although Open Design as a product methodology has appeal to other sectors and the future work into standardisation, regulation, distributed manufacture and recruitment detailed at the conclusion of this thesis has application broader than the medical field

Management, Technology and Learning for Individuals, Organisations and Society in Turbulent Environments

This book presents the collection of fifty two papers which were presented on the First International Conference on BUSINESS SUSTAINABILITY ’08 - Management, Technology and Learning for Individuals, Organisations and Society in Turbulent Environments, held in Ofir, Portugal, from 25th to 27th of June, 2008. The main motive of the meeting was the growing awareness of the importance of the sustainability issue. This importance had emerged from the growing uncertainty of the market behaviour that leads to the characterization of the market, i.e. environment, as turbulent. Actually, the characterization of the environment as uncertain and turbulent reflects the fact that the traditional technocratic and/or socio-technical approaches cannot effectively and efficiently lead with the present situation. In other words, the rise of the sustainability issue means the quest for new instruments to deal with uncertainty and/or turbulence. The sustainability issue has a complex nature and solutions are sought in a wide range of domains and instruments to achieve and manage it. The domains range from environmental sustainability (referring to natural environment) through organisational and business sustainability towards social sustainability. Concerning the instruments for sustainability, they range from traditional engineering and management methodologies towards “soft” instruments such as knowledge, learning, creativity. The papers in this book address virtually whole sustainability problems space in a greater or lesser extent. However, although the uncertainty and/or turbulence, or in other words the dynamic properties, come from coupling of management, technology, learning, individuals, organisations and society, meaning that everything is at the same time effect and cause, we wanted to put the emphasis on business with the intention to address primarily the companies and their businesses. From this reason, the main title of the book is “Business Sustainability” but with the approach of coupling Management, Technology and Learning for individuals, organisations and society in Turbulent Environments. Concerning the First International Conference on BUSINESS SUSTAINABILITY, its particularity was that it had served primarily as a learning environment in which the papers published in this book were the ground for further individual and collective growth in understanding and perception of sustainability and capacity for building new instruments for business sustainability. In that respect, the methodology of the conference work was basically dialogical, meaning promoting dialog on the papers, but also including formal paper presentations. In this way, the conference presented a rich space for satisfying different authors’ and participants’ needs. Additionally, promoting the widest and global learning environment and participativeness, the Conference Organisation provided the broadcasting over Internet of the Conference sessions, dialogical and formal presentations, for all authors’ and participants’ institutions, as an innovative Conference feature. In these terms, this book could also be understood as a complementary instrument to the Conference authors’ and participants’, but also to the wider readerships’ interested in the sustainability issues. The book brought together 97 authors from 10 countries, namely from Australia, Finland, France, Germany, Ireland, Portugal, Russia, Serbia, Sweden and United Kingdom. The authors “ranged” from senior and renowned scientists to young researchers providing a rich and learning environment. At the end, the editors hope and would like that this book will be useful, meeting the expectation of the authors and wider readership and serving for enhancing the individual and collective learning, and to incentive further scientific development and creation of new papers. Also, the editors would use this opportunity to announce the intention to continue with new editions of the conference and subsequent editions of accompanying books on the subject of BUSINESS SUSTAINABILITY, the second of which is planned for year 2011.info:eu-repo/semantics/publishedVersio

The Shopbot Capable of Overcoming Language Barrier for Global E-Commerce

Language is an enormous barrier to global e-commerce. Internet users favor visiting or shopping on Web sites presented in their native language. This research proposes a shopbot with a multilingual ontology to overcome this language barrier. The shopbot, called WebShopper, collects product data from online vendors over the Web and enables customers to execute semantic search using different languages. An empirical study is conducted to evaluate this shopbot. The result shows that customers are able to reach more products and find the real bargains using WebShopper, and the proposed semantic search can improve search results and user satisfaction

Students’ perceptions of and loyalty towards internet banking: the case of the Kingdom of Saudi Arabia and the United Kingdom

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.The contribution of this study based on the development of a cross-cultural universal framework, which is moderated by the culture dimension (uncertainty avoidance) and examines the factors influencing the individuals’ attitudes and behaviour and, ultimately, the individuals’ loyalty towards Internet banking across different countries (KSA and the UK). The study will contribute towards filling the gap in Internet banking literature by: 1) examining customers’ loyalty as a dependent variable of intention; 2) invariant acceptance of customers across the UK and KSA cultures; 3) and integration of the cultural dimension (i.e. uncertainty avoidance) and demographics (i.e. gender and experience) as factors of invariance across the groups. The framework is based on a number of constructs adopted from the validated theories in information systems (IS), psychology and marketing literature perspectives. Specifically from a psychology perspective, using Theory of Reasoned Action (TRA) and Social Cognitive Theory (SCT) constructs, Attitude, Intention, Subjective Norms, Self-efficacy and Actual Behaviour (i.e. intention towards loyalty) were integrated. From a technological perspective, using Technology Acceptance Model (TAM) constructs, Perceived Usefulness and Perceived Ease of Use were integrated. Besides these constructs, the model also integrates constructs of privacy, security, communication, customers’ experience, Internet banking reputation, trust and loyalty from IS, as well as a marketing perspective. To examine the hypothetical relationships within the conceptual model, this study applied the positivist philosophical approach with quantitative methodology. Out of 1000 questionnaires distributed amongst undergraduate students in UK and KSA, 532 were useable, i.e. 53%. Due to the multilevel stages of the conceptual model, structural equation modelling (SEM), based on analysis of moment structure (AMOS), was applied to analyse the data. In addition, invariance analyses were applied to see the differences across the groups (i.e. moderation effect). Initially, sixteen hypotheses were developed in the model but due to the merger of three constructs (i.e. trust, security and privacy ) into one construct (i.e. trust), and the deletion of three constructs (i.e. communication, customers’ experience and Internet banking reputation) at the confirmatory factor analysis (CFA) process, eleven hypotheses were finally retained for examination. The modification indices (MI) suggested three new paths, and hence, the addition of these new hypotheses brought the number up in total to fourteen hypotheses. The results suggest that the conceptualised model was able to fit with the data in both UK and KSA sample. Within the KSA sample, the model explained 45% variance in customer loyalty, but 60% in UK sample. From the path relationships perspectives, out of fourteen hypotheses ten were supported in the KSA and nine were supported in the UK. The results confirm the study’s argument that customer loyalty is the main construct of individuals’ behavioural intention to accept Internet banking. Within specific countries’ context, after behavioural intention, perceived ease of use was a more important predictor of loyalty in the KSA (i.e. b= 0.28); whereas perceived usefulness was a more important predictor of loyalty (i.e. b= 0.27) in the UK. Furthermore, it was noticed that subjective norm towards behavioural intention, perceived usefulness and ease of use was only significant in the KSA sample. The invariance analysis across the countries revealed significant differences between the KSA and the UK for nine hypotheses. Furthermore, invariance analysis also revealed significant differences across the cultural dimension of uncertainty avoidance (i.e. high and low), and the demographical variable of gender (i.e. male and female). Contrary to this, no difference was found for the demographic variable of experience (i.e. high and low). Based on these results, theoretical and practical implications are advised.King Khalid Universit

Expectations and expertise in artificial intelligence: specialist views and historical perspectives on conceptualisation, promise, and funding

Artificial intelligence’s (AI) distinctiveness as a technoscientific field that imitates the ability to think went through a resurgence of interest post-2010, attracting a flood of scientific and popular expectations as to its utopian or dystopian transformative consequences. This thesis offers observations about the formation and dynamics of expectations based on documentary material from the previous periods of perceived AI hype (1960-1975 and 1980-1990, including in-between periods of perceived dormancy), and 25 interviews with UK-based AI specialists, directly involved with its development, who commented on the issues during the crucial period of uncertainty (2017-2019) and intense negotiation through which AI gained momentum prior to its regulation and relatively stabilised new rounds of long-term investment (2020-2021). This examination applies and contributes to longitudinal studies in the sociology of expectations (SoE) and studies of experience and expertise (SEE) frameworks, proposing a historical sociology of expertise and expectations framework. The research questions, focusing on the interplay between hype mobilisation and governance, are: (1) What is the relationship between AI practical development and the broader expectational environment, in terms of funding and conceptualisation of AI? (2) To what extent does informal and non-developer assessment of expectations influence formal articulations of foresight? (3) What can historical examinations of AI’s conceptual and promissory settings tell about the current rebranding of AI? The following contributions are made: (1) I extend SEE by paying greater attention to the interplay between technoscientific experts and wider collective arenas of discourse amongst non-specialists and showing how AI’s contemporary research cultures are overwhelmingly influenced by the hype environment but also contribute to it. This further highlights the interaction between competing rationales focusing on exploratory, curiosity-driven scientific research against exploitation-oriented strategies at formal and informal levels. (2) I suggest benefits of examining promissory environments in AI and related technoscientific fields longitudinally, treating contemporary expectations as historical products of sociotechnical trajectories through an authoritative historical reading of AI’s shifting conceptualisation and attached expectations as a response to availability of funding and broader national imaginaries. This comes with the benefit of better perceiving technological hype as migrating from social group to social group instead of fading through reductionist cycles of disillusionment; either by rebranding of technical operations, or by the investigation of a given field by non-technical practitioners. It also sensitises to critically examine broader social expectations as factors for shifts in perception about theoretical/basic science research transforming into applied technological fields. Finally, (3) I offer a model for understanding the significance of interplay between conceptualisations, promising, and motivations across groups within competing dynamics of collective and individual expectations and diverse sources of expertise
