A Quantitative Study of Risk Scores and the Effectiveness of AI-Based Cybersecurity Awareness Training Programs

Cybersecurity awareness training plays a dynamic role for organizations in certifying resources\u27 accessibility. This paper determines the correlation between an employee\u27s risk score and the effectiveness of AI-based security awareness training that deals with cyber threats. The research uses the Unified Theory of Acceptance and Use of Technology to update prior research, revealing that at-risk employees\u27 behavior and information security awareness training implementation make up successful interventions. However, those studies did not discuss AI training, and so this research fills that literature gap. This study used a quantitative research design. The researcher analyzed survey responses using Pearson\u27s Correlation and an independent t-test to determine statistically significant relationships and differences between employees\u27 risk scores and an AI-based security awareness training programs\u27 effectiveness. The calculations came from a sample of 200 participants from two different organizations. The Pearson product correlation of employee\u27s risk scores and the effectiveness of the security awareness training program was statistically significant. The researcher also conducted an independent-samples t-test to compare the employees\u27 risk scores by gender. There were no significant differences in scores. Male was higher than female ones. The mean difference was minimal. The findings herein help interpret the role of information security awareness training in the workplace, promoting behavioral changes that would impede data violations by including the users\u27 vulnerability and the severity of intimidation, and the response to a threat in prognosticating behavior intentions

A telepresence environment for concurrent life-cycle design and construction

Construction projects normally involve transient 'virtual organisations', where a multidisciplinary project team works together on the design and construction of a facility. Many of these participants often work independently while taking decisions that inevitably affect others. The research described in the thesis involved examining the adoption of concurrent engineering (CE) principles by the construction industry as a way to reduce the problems posed by the fragmentation of the industry, and to enhance its competitiveness. An important aspect of concurrent engineering in construction is the need for effective communication of design information between all members of the project team and across all stages of the constructed facility's life-cycle. The thesis describes the development of a communications infrastructure for Concurrent Life-Cycle Design and Construction. [Continues.

Enterprise Architecture Context Analysis Proposal

The enterprise architecture (EA) is defined as a coherent and consistent set of principles and rules that guide system design. In the EA modelling methods, an enterprise is identified with institution, business or administrative unit. The EA development methods mostly focus on the EA internal problem visualization, as well as on the procedural and different viewpoint approaches. However, in this paper, author would like to emphasize the EA context specification. The first part of the paper covers presentation of different meanings of context in information science. Next, the discussion on the EA context in related publications is included. The third part comprises a proposal of considering EA stakeholders, principles and other information technology (IT) systems as an EA context. Finally, a short case study is included for the context visualization

The mobile information access experience - A user perspective

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Mobile technologies, such as mobile phones, smartphones and Palmtop computers, are in an upwards trend and earliest models of such devices are already available to end-users to communicate and access multimedia content on-the-move. As a logical outcome of this development in mobile technologies and devices, content provider companies have already started investing and piloting mobile multimedia content distribution and broadcasting technologies. Nevertheless, no matter how cutting-edge technology is and no matter how stylish the mobile devices are, the ultimate success of wireless communication technologies and devices are directly associated with the user adoption and embrace of these new equipment and technologies. In this perspective, since multimedia content, for mobile or not, is ultimately produced for the education and/or enjoyment of viewers, the user's perspective concerning the presentation quality is surely of equal importance as objective Quality of Service (QoS) technical parameters, to defining distributed multimedia quality. In order to comprehensively understand user experiences whilst accessing information using mobile devices and technologies, we investigate user-mobile device interaction and look into the surrounding issues in a uniform manner by combining multiple aspects: user initial device experience (Out-of-Box Experience), mobile information access in a real-world context, device impact on user information access and perceptually tailored multimedia content impact on user information assimilation and satisfaction. Accordingly, an extensive experimental investigation has been undertaken to see how user experiences varied based on device familiarity, device type, real-world context and variable locations. The findings has shown that the overall perception, and effectively the user information access experience, is affected and improved when multimedia content is tailored according to user device type and context. Thus highlights that the future of mobile computing necessitates two-faceted research, which should combine both a user as well as a technical perspective

Tagging amongst friends: an exploration of social media exchange on mobile devices

Mobile social software tools have great potential in transforming the way users communicate on the move, by augmenting their everyday environment with pertinent information from their online social networks. A fundamental aspect to the success of these tools is in developing an understanding of their emergent real-world use and also the aspirations of users; this thesis focuses on investigating one facet of this: the exchange of social media. To facilitate this investigation, three mobile social tools have been developed for use on locationaware smartphone handsets. The first is an exploratory social game, 'Gophers' that utilises task oriented gameplay, social agents and GSM cell positioning to create an engaging ecosystem in which users create and exchange geotagged social media. Supplementing this is a pair of social awareness and tagging services that integrate with a user's existing online social network; the 'ItchyFeet' service uses GPS positioning to allow the user and their social network peers to collaboratively build a landscape of socially important geotagged locations, which are used as indicators of a user's context on their Facebook profile; likewise 'MobiClouds' revisits this concept by exploring the novel concept of Bluetooth 'people tagging' to facilitate the creation of tags that are more indicative of users' social surroundings. The thesis reports on findings from formal trials of these technologies, using groups of volunteer social network users based around the city of Lincoln, UK, where the incorporation of daily diaries, interviews and automated logging precisely monitored application use. Through analysis of trial data, a guide for designers of future mobile social tools has been devised and the factors that typically influence users when creating tags are identified. The thesis makes a number of further contributions to the area. Firstly, it identifies the natural desire of users to update their status whilst mobile; a practice recently popularised by commercial 'check in' services. It also explores the overarching narratives that developed over time, which formed an integral part of the tagging process and augmented social media with a higher level meaning. Finally, it reveals how social media is affected by the tag positioning method selected and also by personal circumstances, such as the proximity of social peers

CHORUS Deliverable 2.2: Second report - identification of multi-disciplinary key issues for gap analysis toward EU multimedia search engines roadmap

After addressing the state-of-the-art during the first year of Chorus and establishing the existing landscape in multimedia search engines, we have identified and analyzed gaps within European research effort during our second year. In this period we focused on three directions, notably technological issues, user-centred issues and use-cases and socio- economic and legal aspects. These were assessed by two central studies: firstly, a concerted vision of functional breakdown of generic multimedia search engine, and secondly, a representative use-cases descriptions with the related discussion on requirement for technological challenges. Both studies have been carried out in cooperation and consultation with the community at large through EC concertation meetings (multimedia search engines cluster), several meetings with our Think-Tank, presentations in international conferences, and surveys addressed to EU projects coordinators as well as National initiatives coordinators. Based on the obtained feedback we identified two types of gaps, namely core technological gaps that involve research challenges, and “enablers”, which are not necessarily technical research challenges, but have impact on innovation progress. New socio-economic trends are presented as well as emerging legal challenges

Distributed multimedia quality: The user perspective

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Distributed multimedia supports a symbiotic infotainment duality, i.e. the ability to transfer information to the user, yet also provide the user with a level of satisfaction. As multimedia is ultimately produced for the education and / or enjoyment of viewers, the user’s-perspective concerning the presentation quality is surely of equal importance as objective Quality of Service (QoS) technical parameters, to defining distributed multimedia quality. In order to extensively measure the user-perspective of multimedia video quality, we introduce an extended model of distributed multimedia quality that segregates quality into three discrete levels: the network-level, the media-level and content-level, using two distinct quality perspectives: the user-perspective and the technical-perspective. Since experimental questionnaires do not provide continuous monitoring of user attention, eye tracking was used in our study in order to provide a better understanding of the role that the human element plays in the reception, analysis and synthesis of multimedia data. Results showed that video content adaptation, results in disparity in user video eye-paths when: i) no single / obvious point of focus exists; or ii) when the point of attention changes dramatically. Accordingly, appropriate technical- and user-perspective parameter adaptation is implemented, for all quality abstractions of our model, i.e. network-level (via simulated delay and jitter), media-level (via a technical- and user-perspective manipulated region-of-interest attentive display) and content-level (via display-type and video clip-type). Our work has shown that user perception of distributed multimedia quality cannot be achieved by means of purely technical-perspective QoS parameter adaptation
