Trust Evaluation of a System for an Activity

International audienceWhen users need to perform a digital activity, they evaluate available systems according to their functionality, ease of use, QoS, and/or economical as- pects. Recently, trust has become another key factor for such evaluation. Two main issues arise in the trust management research community. First, how to de- fine the trust in an entity, knowing that this can be a person, a digital or a physical resource. Second, how to evaluate such value of trust in a system as a whole for a particular activity. Defining and evaluating trust in systems is an open problem because there is no consensus on the used approach. In this work we propose an approach applicable to any kind of system. The distinctive feature of our pro- posal is that, besides taking into account the trust in the different entities the user depends on to perform an activity, it takes into consideration the architecture of the system to determine its trust level. Our goal is to enable users to have a per- sonal comparison between different systems for the same application needs and to choose the one satisfying their expectations. This paper introduces our approach, which is based on probability theory, and presents ongoing results

E-government and Digital Divide in Hail City: a Quantitative, Older Adults Study

The subject of information and communication technologies adoption, Internet and e-government services in particular, have been widely investigated by researchers. It is an indication of the significant roles that can be brought to individuals and societies by such advanced technologies in which enhancing quality of life is the ultimate goal. Unfortunately, many groups within societies are not gaining the advantages and benefits of the Internet and e-government because they are less receptive to ICTs. This has created a phenomenon known as the digital divide. Amongst these groups are the older adults. The rising attention towards the elderly is due to the increasing life expectancy. Thanks to health technological advancements and life style improvements, which are leading to better qualities of life, countries around the globe have older adults population rate larger than ever before. Saudi Arabia is no exception, as demographic characteristics have been changing in which life span is increasing and fertility is decreasing. However, literature of older adults and technology adoption, particularly adoption of Internet and e-government lacks the context of developing countries and the Arab world. Therefore, using this as a motivation, this study aims to identify, explain and understand the adoption, use and diffusion of e-government services within the older adults population (50+) of a vicinity in Saudi Arabia. The study uses a quantitative research method along with a positivist epistemology. The data collection technique involved distributing survey questionnaires to households’ residents (50+) in Hail city (area and simple random sampling). A small-scale pilot study was initially used (n=257) to validate and enhance the survey questions, followed by a wide-scale final study (n=937). Findings revealed that with regards to Internet adoption, age-based, gender-based, education-based and health-based digital divides do exist within the elderly population. It was also found by model analysis that elderlies’ intentions of whether to use or not use e-government services are considerably impacted by attitudinal, subjective norms, control and trustworthiness factors, excluding the two factors of image and trust in government, which showed insignificance. The study makes positive contributions to related literature, policy makers and industry. Finally, due to the restraints of time, finance and manpower, this study examined only a small portion of the whole population of Hail city; therefore, generalisations of findings cannot be claimed

FACTORS THAT AFFECT THE ACTUAL USE OF M-GOVERNMENT FROM THE USER PERSPECTIVE: THE CASE OF ABU DHABI GOVERNMENT

In recent years, the evolution of information technologies has shown vast growth. The popularity of and demand for mobile smartphones and applications also continue to grow, so governments are developing mobile business models and moving from electronic-government (e-government) to mobile-government (m-government) practices in order to enhance functioning and increase the efficiency and effectiveness of their services. However, there are very few pieces of systematic evidence related to m-government implementation and the level of actual use of m-government applications and services in less developed countries. Therefore, the current study aims to identify factors that affect Abu Dhabi citizens\u27 and residents’ actual use of m-government applications. Moreover, this study examines the relationships between m-government service and technology characteristics, perceived ease-of-use and usefulness, user past experience, attitude toward m-government use, behavioural intention to use m-government, and actual use of m-government. In addition, 22 hypotheses are developed and tested using a sample of 279 m-government service users in Abu Dhabi, collected through a cross-sectional survey. After developing and testing the conceptual model, the results show that the suggested m-government factors are crucial to achieving user adoption of m-government services while excluding the factors of accuracy, convenience, risk, and privacy. Furthermore, the results of the study are expected to enhance the existing theorization of mobile technology factors that affect user acceptance and actual usage of m-government services. From a practical perspective, this study provides a recommendation to decision-makers and developers of m-governments in order to enhance and increase the level of actual usage of their applications and services

The Privacy Paradox: Factors influencing information disclosure in the use of the Internet of Things (IoT) in South Africa

The Internet of Things (IoT) has been acknowledged as one of the most innovative forms of technology since the computer, because of the influence it can have on multiple sectors of physical and virtual environments. The growth of IoT is expected to continue, by 2020 the number of connected devices is estimated to reach 50 billion. Recent developments in IoT provide an unprecedented opportunity for personalised services and other benefits. To exploit these potential benefits as best as possible, individuals are willing to provide their personal information despite potential privacy breaches. Therefore, this paper examines factors that influence the willingness to disclose personal information in the use of IoT in South Africa (SA) with the use of the privacy calculus as the theoretical underpinnings of this research. The privacy calculus accentuates that a risk-benefit trade off occurs when an individual decides to disclose their personal information, however, it is assumed that there are more factors than perceived risks and perceived benefits that influence information disclosure. After analysing previous literature, this study identified the following factors; information sensitivity, privacy concerns, social influence, perceived benefits, (perceived) privacy risks and privacy knowledge as possible key tenants in relation to willingness to disclose personal information. This research took on an objective ontological view, with the underlying epistemological stance being positivistic. The research incorporated a deductive approach, employing the use of a conceptual model which was constructed from a combination of studies orientated around privacy, the privacy calculus and the privacy paradox. Data for this research was collected using the quantitative research approach, through the use of an anonymous online questionnaire, where the targeted population was narrowed down to the general public residing within SA that make use of IoT devices and/or services. Data was collected using Qualtrics and analysed using SmartPLS 3. SmartPLS 3 was used to test for correlations between the factors which influence information disclosure in the use of IoT by utilising the complete bootstrapping method. A key finding was that the privacy paradox is apparent within SA, where individuals pursue enjoyment and predominantly use IoT for leisure purposes, while individuals are more likely to adopt self-withdrawal tendencies when faced with heightened privacy concerns or potential risks

Digital media exposure, political attitudes and perceptions as antecedents of voting intentions: a Zimbabwean perspective

Thesis (Ph.D. (Business Science))--University of the Witwatersrand, Faculty of Commerce, Law and Management, School of Economic & Business Sciences, 2017With the contemporary diffusion of media technology, the majority of researchers have come to position the Internet as a political instrument that has the potential to stimulate consumer behaviour. The Internet has expanded persistently as a news source and digital technologies have become more accessible and abound with user generated content. These digital media backdrops afford a valuable opportunity to empirically examine the effects of digital media effects on consumer decision-making. It is therefore important to examine how consumer perceptions and attitudes towards voting impact their decision-making in order for political marketers or politicians to develop coherent strategies that offer a conducive environment sufficient to influence voting decision-making. Whereas previous studies on voting behaviour have merely explored voting behaviour in a global context, the current study investigates the effect of digital media exposure on perceptual and cognitive constructs within a Zimbabwean context. Moreover, few studies have explored this topic in a consumer behaviour context amongst the Zimbabwean constituency. This study aims to determine whether digital media exposure influences voter-consumers’ intention to vote in subsequent Zimbabwe presidential elections. In order to empirically test the effect of digital media exposure on perceived image of a political party (PI); perceived image of a presidential candidate (PPC); attitude towards voting (ATV) and voting intention (VI), a conceptual model premised on the reviewed political marketing literature was developed. The model proposed four distinct domains that drive voting intentions. In this conceptualised model, digital media exposure is the predictor variable, while perceived image of the presidential candidate, attitude towards voting, perceived image of the political party, are mediators and voting intention is the single outcome variable. By exploring the significance of digital media use on voter behaviour, this study contributes towards specific contextual knowledge on consumer behaviour and political marketing in developing countries particularly Zimbabwe. The present study is positioned in the positivist research methodology, and assumes a deductive approach within the quantitative paradigm to test the proposed hypotheses. This study uses stratified probability sampling to arrive at the required number of provinces for the study. Using quantitative methodologies based on the nature of the research questions, data were collected through a self-administered questionnaire from 305 eligible voters from selected Provinces and Districts in Zimbabwe selected through stratified probability sampling to arrive at the required number of provinces for the study.The measuring instrument was designed from existing scales, which were adapted to suit the present study. The data analysis ii | P a g e was done in SPSS 24 for demographic data analysis and AMOS 24 was used for the structural equation modelling and path modelling. The findings support all the hypotheses in a significant way except H1 and H5. Likewise, voter-consumers’ perception of the presidential candidate has an influence on the attitude towards voting and all latter perceptual and attitudinal variables have significant influence on voting intention. Important to note about the study findings is the fact that digital media exposure has a stronger effect on perceived image of the political party (H3) than attitude towards voting (H2). However, perceived image of the political party strongly influence attitude towards voting. Remarkably, the relationship between perceived image of the presidential candidate and attitude towards voting is robust. The findings indicate that digital media exposure can have a strong influence on voting intention through attitude towards voting. The contribution of this study is threefold: Firstly, by exploring the significance of digital media exposure on voting behaviour, this study adds to contextual knowledge on relationship marketing, political brand management and experiential marketing (the final stage of the mental brand responses), consumer marketing and specifically, political marketing. Secondly, as a growing body of literature explores the use of digital technology in political campaigning/marketing to create a competitive advantage, this study provides researchers with a broad understanding of this phenomenon among voting citizens in developing countries particularly Zimbabwe. Theoretically, it is positioned in political marketing and contributes to theoretical literature that focuses on consumer behaviour, branding and brand relationship. Lastly, by investigating digital media exposure and its influence on consumers’ voting intention, the findings provided political marketing practitioners with a better understanding of strategies that can be employed to influence citizens’ voting behaviour, through the use of digital media. The study thus submits that politicians ought to pay attention to both media agenda and brand image in order to build a positive attitude towards voting which significantly influences the intention to vote. In order to maximise voter ‘purchase’, marketers can implement strategies to encourage positive behaviour from voter-consumers and exploit multi-sensory experiences in order to influence voting intentions. The study makes a significant contribution to brand management literature and consumer behaviour literature by systematically exploring the impact of media exposure on brand image and attitude towards voting in Zimbabwe. The study demonstrates that political data can be used in consumer behaviour studies and provides a theoretical method for predicting voting intentions using voter behaviour in the form of voter perception of political parties and perceived image of a presidential candidate as well as attitude towards voting. The study further highlights the significance of using digital technologies and ingenuity to create a comparative advantage as well as a differential advantage.MT 201

E-government systems success and user acceptance in developing countries: The role of perceived support quality

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Electronic government (e-Government) projects create numerous benefits and opportunities for both governments and citizens worldwide. Accordingly, the increasing interest in e-Government raises the issue of how governments can increase citizen adoption and usage of their on-line services. The successful adoption of Information Communication Technologies (ICTs), the explosive increase in Internet usage and the rapid development of e-commerce in private sectors have placed pressure on public organisations to interact electronically with citizens. Conversely, the success of e-Government does not depend only on the supplier side, but also on the demand side and the willingness to adopt the on-line service. The concept of e-Government was developed and implemented initially in industrialised countries. Consequently, it should not be assumed that this concept is automatically appropriate for developing countries. Thus far, e-Government still faces major challenges as it continues to expand in developing countries. Moreover, when introducing e-Government to developing nations, it is anticipated that more effort will be necessary than in developed countries. The objective of various e-Government initiatives has moved in the past decade towards establishing services offering greater accessibility for citizens. As a result, it is necessary to examine all possible factors to explain citizens' adoption and usage of such systems. Hence, numerous models of e-Government adoption and intention to use and their extensions have been proposed and applied to empirical studies. Obviously, e-Government has occurred due to the technological revolution following the diffusion of the Internet and the success of information systems (IS) in organisations and e-Commerce. However, regardless of their success within the general IS context, the models are limited in terms of considering the diversity of users; they tend to assume that all end-users are homogeneous. The end-users of e-Government systems are more diverse than e-Commerce, with comparisons of wider layers of user groups (for example, elderly and less well-educated people) who are more likely to encounter problems while interacting with e-Government systems. IS literature confirmed that users’ technical capabilities and management support are influenced by their technical knowledge and expertise. Therefore, this research argues that perceived support quality is a new way of looking at citizens’ adoption and usage in the e-Government system’s field and a major factor of e-Government system’s acceptance, particularly in developing countries. This study is the first to examine the roles of perceived support quality and support satisfaction in the context of government-to-citizen (G2C), and it aims to advance knowledge within the field of e-Government by revealing the roles of perceived support quality and satisfaction towards behaviour intention and usage in developing countries. The proposed model builds upon Wixom and Todd’s (2005) theoretical model, which, in turn, was based on the integration of DeLone and McLean model (1992) into the technology acceptance model (TAM). The strength of the integrated model lies in its ability to guide both IT design and predict usage behaviours towards the system under investigation, and assume the overall theoretical model to maintain validity in G2C settings. Thirteen hypotheses were formulated to test the proposed research model. Behaviour intention to use e-Government services was proposed as the dependent variable, while the independent variables were information quality; information satisfaction; system quality; system satisfaction; social influence; performance expectancy; effort expectancy; perceived support quality and support satisfaction. A quantitative approach was deemed best suited to test the proposed model. Using a survey method (i.e. paper-based and an on-line survey), a total of 1252 responses was collected; however, only 628 were analysed. To test the proposed e-Government model, the state of Kuwait was chosen as the application area and the official website of Kuwait Government On-line Services (KGOS) was selected, since it offers a number of services on-line. Elements were citizens who have had prior experience with the KGOS website, and the survey was conducted from 5th August to 10th October 2010. Structural equation modelling (SEM) was selected as the statistical analysis technique with the Analysis of Moment Structures (AMOS) software. A total of 40 percent of the variance among the factors of support satisfaction, system satisfaction, information quality, effort expectancy and performance expectancy was explained by behavioural intention to use an e-Government system. All hypotheses were supported except for one. The findings confirm the significance to the support quality perceived by citizens, and also provide insights into whether user satisfaction literature and TAMs should be integrated to explain citizens’ intention to use e-Government systems. Thus, in terms of the theoretical implications, this study highlights the significance of recognising theoretical relationships when performing empirical research in e-Government settings. Consequently, to capture both the technical aspects and the services provided on-line, a new variable was introduced and renamed ‘perceived support quality’. Additionally, the model offers managers a new perspective for dealing with e-Government adoption by signifying the importance of support quality perceived by citizens. The proposed model provides government decision-makers in developing countries with an appropriate approach to determining which factors require attention in order to reap the highest benefits from e-Governments’ projects. This suggests paying less attention to the social influence (SI) factor and consider instead improving the quality of on-line support citizens demand

Determinants of internet banking adoption by banks in Ghana

Growth in information and communication technology (ICT) is drastically changing the way businesses, especially in the service industries, are conducted. The financial services industry and banking in particular, is not excluded from this technology explosion. Internet banking, even though not new in advanced countries, is a new transaction channel being used by banks in some parts of Africa, especially Ghana, to offer various products and services to their customers. However, this medium has not been fully exploited by these banks as there are many hurdles the banks must triumph over. In deploying this technology and these systems, there are several factors which banks must take into consideration before fully deploying such a system to their customers, hence the motivation for this study. The absence of suitable and sufficient knowledge on this topic also exposes a “rhetoric versus reality” argument of whether the intention to adopt Internet banking is critical to the strategies and ultimate success of banks in Ghana. For banks to stay ahead of competition as well as to attract and maintain their clientele, it is of paramount importance to gather and link the perspectives of both clients and bank managers in order for banks to ensure that they perform according to the needs and expectations of their clients. In order to achieve the intended results, an empirical study was conducted by taking into consideration the viewpoints of both bank clients and bank managers in determining the factors that customers take into consideration before adopting the Internet banking medium. The primary aim of this study was to quantify significant relationships between the selected variables. Therefore the positivism research paradigm was used, while the phenomenological paradigm was employed for the measuring instruments. Because multiple sources of data were used, from the perspectives of banking clients and managers in Ghana, methodological triangulation was adopted for this study. The results of the empirical investigation showed that both groups (clients and managers) considered the variables of market share, technology acceptance, diffusion of innovation, organisational variables, organisational efficiency, and business strategy to have direct influence on the adoption of Internet banking. However, they differed in opinion concerning the degree of influence of these variables. The bank managers’ responses leaned more towards strong agreement with the importance of these variables than did those of the bank clients. Thus, for bank clients to readily adopt the Internet banking medium for their banking transactions, bank managers must take a closer look at these determinant factors described in the study. The study showed that the population group, educational and income levels exerted an influence on the perceptions clients have regarding Internet banking adoption factors. It was found that the higher the education and income levels of the clients, the easier it was for them to adopt Internet banking. Also, the male group dominated the use of the Internet banking. This is supported by the fact that there is a growing middle class in Ghana that falls within this category of banking clients
