Abstract:

Self service providers are making such systems which offer faster and more flexible service to the user. Most of us are familiar about self service technologies such as Kiosk, Auto Teller Machine, Self Check in machine, Self payment machine etc. Unfortunately, users are not using these SSTs commonly as advancement has been occurring in SSTs. Sometimes, people look annoyed and feel fear to use such kind of technology at public spaces. Generally, these systems need interaction between users and technology to create service outcome instead of interacting with a service personnel. These technological interfaces have been called Self-service technologies (SSTs). Yet, not all users choose to use the new technologies and they still feel some hesitations to adopt this technologies in this case SSTs. This study investigated the factors that make users hesitate to use and adopt SSTs.

Abstract:
Abstract Critical environmental situation requires academics and practitioners of various disciplines join efforts at planning sustainable development of the society. In information systems research, Green Information Systems and Technologies domain is the one that directly contributes to strengthening environmental values of individuals, communities, and organizations. Abundance of technology influences people most of the time. Although this influence is not always positive, research on persuasive technologies and behavior change support systems searches for the beneficial ways to utilize the impact of information systems on the daily activities of individuals. Ability to assist with encouraging certain behaviors is a defining characteristic of many contemporary systems and devices. Building on the knowledge obtained from the health domain, this dissertation investigates using persuasive technologies for fostering pro-environmental behavior change. Theoretical frameworks of the articles included in the dissertation are based primarily on the Persuasive Systems Design (PSD) model, accompanied by the other prominent socio-psychological theories commonly utilized in information systems research. This dissertation focuses on finding out how to encourage people to adopt and continue using mobile applications designed to assist with acquiring sustainable habits and behaviors. The dissertation is composed of the historical analysis, systematic literature review, and four experimental studies that explore different aspects of persuasive Green IS/IT. Besides analyzing existing research using PSD model as a tool for evaluation, new empirical studies provide fresh insights on Green IS/IT designed for behavior change. Addressed topics include technology adoption and continuance intention, perceived persuasiveness, self-disclosure and risk, endogenous motivations, gamification, and cognitive absorption. Conducted statistical analyses investigate relationships among PSD constructs and other related concepts to discover factors that can convince people initiate and continue using Green IS/IT to develop or maintain environmentally sound practices. Overall, the results reveal a high potential of the PSD model to become a vehicle for enhancement of the existing Green IS/IT. The dissertation provides implications for both academics and practitioners as well as suggestions for the future evolvement of persuasive Green IS/IT research
Tiivistelmä Ympäristön ja ilmaston vakava tilanne vaatii kaikilta osapuolilta kestävää kehitystä tukevaa toimintaa. Niin sanotut ‘vihreät’ tietojärjestelmät ja informaatioteknologiat pyrkivät vaikuttamaan ihmisten käyttäytymiseen vahvistamalla yksilöiden, yhteisöjen ja organisaatioiden ympäristöarvoja ja niiden mukaista käyttäytymistä. Yltäkylläinen teknologiatarjonta vaikuttaa käyttäytymiseemme koko ajan. Vaikka tämä vaikutus ei aina olekaan positiivista, vakuuttavien ja suostuttelevien teknologioiden sekä käyttäytymisen muutosta tukevien järjestelmien tutkimus pyrkii etsimään niitä hyödyllisiä keinoja, joilla tietojärjestelmien avulla voidaan vaikuttaa myönteisesti jokapäiväiseen elämäämme. Monien nykyaikaisten järjestelmien ja laitteiden perusominaisuutena voidaankin nykyään pitää niiden kykyä rohkaista ja kannustaa käyttäjiä myönteiseen kohdekäyttäytymiseen. Tämä väitöskirja rakentuu erityisesti terveystoimialalta omaksuttuun suostuttelevia teknologioita koskevaan tutkimustietoon ja pyrkii soveltamaan tätä ympäristöystävällisen käyttäytymisen vahvistamiseen. Tämän väitöstutkimuksen johtavana teoreettisena viitekehityksenä toimii Persuasive Systems Design -malli (PSD). Sen lisäksi hyödynnetään joitakin muita tietojärjestelmätutkimuksessa hyödynnettyjä sosiaalipsykologian teorioita. Väitöskirja keskittyy tarkastelemaan, miten voidaan kannustaa ottamaan käyttöön mobiilisovelluksia, jotka on jo alun perin suunniteltu tukemaan kestävän kehityksen kannalta myönteistä käyttäytymistä ja käyttäytymisen muutosta, sekä jatkamaan niiden käyttöä. Väitöskirja koostuu aihealueen historiallisesta analyysistä ja systemaattisesta kirjallisuuskatsauksesta sekä neljästä kokeellisesta tutkimuksesta, jotka tutkivat ’vihreiden’ tietojärjestelmien ja informaatioteknologioiden vakuuttavia ja suostuttelevia ohjelmisto-ominaisuuksia. Sen lisäksi että olemassa olevaa kirjallisuutta on analysoitu PSD-mallia käyttäen, samaan malliin pohjautuvat empiiriset tutkimukset tuottavat tuoreita oivalluksia käyttäytymisen muutosta tukevaan suunnitteluun liittyen. Tutkimuksessa tarkastellaan teknologian käyttöönottoa, aikomuksia jatkaa teknologian käyttöä, koettua vakuuttavuutta ja suostuttelevuutta, sensitiivisten tietojen jakamista ja siihen liittyviä riskejä, sisäsyntyistä motivaatiota, pelillistämistä sekä kognitiivista absorptiota. Tilastollisten analyysien avulla tarkastellaan PSD-mallin ydinkäsitteiden ja muiden konstruktien välisiä suhteita, jotta tunnistettaisiin niitä tekijöitä, joiden avulla voidaan vaikuttaa hyödyllisten ‘vihreiden’ tietojärjestelmien ja informaatioteknologioiden käyttöönottoon ja käytön jatkamiseen, ja yleisemmin kannustamaan ympäristöystävällisiin käytänteisiin. Tutkimustulokset osoittavat PSD-mallin merkityksen kestävää kehitystä tukeville tietojärjestelmille ja informaatioteknologioille. Suoritetun tutkimuksen perusteella ehdotetaan teemoja jatkotutkimusta varten. Väitöstutkimuksen tuloksilla on merkitystä sekä tieteenharjoittajille että käytännön soveltajille

Abstract:
Two main phenomena have recently become prominent in respect to information management. First, there has been a rapid increase in the number and variety of sources of information on the World Wide Web and in the role of users as content providers. In parallel, there has been an evolution of web technologies to support the creation, storage, and sharing of information. These developments have led to new paradigms such as cloud computing, crowdsourcing, and social collaboration. The second phenomenon is the increasing need of organizations to effectively and efficiently benefit from massive data — termed “big data” (a term also linked recently to cloud computing and to social network data). These two phenomena both indicate new needs and new technological opportunities. Traditionally, information management has been based on storing data in structured databases, where the structure reflects some expected uses, and managed with (at least some) central control (even for distributed data). These assumptions, however, do not fit the new paradigms, where flexible information management is needed to support different views of multiple users, unknown future uses, no central control, and new unexpected sources. This thesis explores an approach to information management intended to provide the flexibility to support multiple, varied, and emerging sources where uses of information may not be known in advance. The approach employs three principles. First, data should be stored independent of any pre-conceived “containers” that reflect anticipated uses (classes, tables). Second, reconciliation of meaning of data can be done by abstraction of the properties the data represent. Third, classification can be created as needed depending on the application, based on some usefulness considerations. The thesis has two objectives. First, suggest how to apply these principles in the implementation of a flexible information management system. Second, demonstrate how semantic web technologies can be used to implement this approach. These technologies include triplestores (storing data in resource description framework), related query languages (SPARQL), and formal ontologies (Web Ontology Language). The thesis describes a prototype implementation, demonstrates it on a case study, and discusses its advantages compared to traditional database systems.

Abstract:

During the autumn project we explored how mobile technologies could be used to improve collaboration in distance education in developing countries. During this study we identified the importance of discussion groups. In this thesis continuing from the autumn project I traveled to Uganda and administered interview on the BED students in order to understand better how discussion groups are formed and managed, hence understanding better the activities technology can support. In this study we used different methods of data collection. Since we had already done a study in the previous semester we used some the information we hd gathered before to inform us about some aspect. We also used a questionnaire as earlier mentioned and observation since we were in Uganda during a face-to-face session. We presented the results which informed us and we characterised the discussion groups in two that is assignment discussion group and general discussion group giving the characteristics of each in detail. In the results presentation we grouped the chapter into major sub section that need support. We then anaylsed the data collected were we present it in form of scenarios without technology support. In this chapter we have different possibility when Markus whats to create group, join group, leave a group, etc. In here we identify some activities that need support e.g. group management, coordination, communication and collaboration. We then presented the services in the design chapter in use cases and described the different use cases. These use cases helped us to know the detail functionalities that we need to support. There after we developed demonstration prototype to demonstrate some of the functionalities of the design. Though we would have liked to have every thing on our demonstration prototype we just did a few services to demonstrate what we needed. We then evaluated our demonstrator aganist the scenarios we had earlier in the analysis by trying to see how the demonstrator solve some of the problems Markus encounted.

Abstract:
In the wake of rapidly progressing technology, educational institutions are searching for more innovative uses of educational technologies to teach the new kind of students who are entering into these institutions. The Net Generation (NG), are believed to have grown up surrounded by technology and this poses a challenge of understanding how well-designed technology improvements can enhance a student's educational experience. The main reason as to incorporating technology with education is without a doubt to improve a student's engagement and learning. There is increasing interest in the application of cognitive neuroscience in educational practice to advice on how to improve the learning content to have a more positive impact on the NG with an understanding of the brain. Research does show that if technology is not weaned correctly, can have negative effects and addictive behaviours emerge such as craving, concealing, and lying. There is no link, to the author's knowledge, between these scientific findings of neuroscience and advising institutions on changes and implementations necessary to the learning material. This study sets out to link the three; using Piaget's Theory of Cognitive Development as the guide of the different categories of the NG and a detailed literature review of other theories of this phenomenon, the three elements (Learning, Technology and Neuroscience) were investigated. Using secondary analysis the researcher was able to analyse different data sets of the different age groups as stipulated by Piaget's Theory. Each study sought to investigate the NG with different learning MTs and the effects it had on them. The results were ran through different statistical tests revealing positive links of the three aforementioned elements. The findings asserted that students learning with these multimedia obtained significantly greater learning achievement in comparison to those who were not. Not only so, but these same students were also more motivated by using technology in the classroom for learning and exhibited increased functional connectivity during their engagement. Finally, the three elements were linked by developing a life-stage technology consumption model that will be capable of guiding instructors, NG and the consumers of various MTs.

Abstract:
Electronic government (e-government) is how the providers of public services interact with the citizen and business via electronic means. The internet is the most commonly used electronic channel. E-government can provide major benefits to citizens and businesses by making the delivery of public services more efficient and effective. However, recent advances in mobile technology have offered the potential to support government services at various levels. This has made it possible to deliver services to the citizens who have no convenient physical access to government services, for example, people living in rural areas and those who are continually on the move, such as business professionals. This study explores the possibilities of effectiveness, resistance, opportunities and issues related to supporting government services delivery through using mobile cellular technologies. This research study focused on the South African and Nigerian contexts. The focus was to explore various ways that the government can use mobile technologies to improve the provision of government services. A major output of this research work is a conceptual framework to guide mobile government implementation as a vehicle for delivery of government services. Literature from both academic and professional domains were consulted throughout the study. Furthermore, a case study research was conducted in two organisations, which are different in terms of cultural and transformative settings (one in South Africa and another in Nigeria). The study followed an interpretive research approach, and collected data through semi-structured interviews in the two organizations. The data gathered were relevant to the implementation of m-government systems. The study relied on two underpinning theoretical frameworks, namely Structuration Theory and Actor Network Theory to understand the socio-technical factors affecting the implementation of m-government systems in government organisations. The perspective of duality of structure and moments of translation from both Structuration Theory and Actor Network Theory were adopted to analyse the data collected in the case study organisations.

Abstract:

Traditionally, firewalls and access control have been the most important components used in order to secure servers, hosts and computer networks. Today, intrusion detection systems (IDSs) are gaining attention and the usage of these systems is increasing. This thesis covers commercial IDSs and the future direction of these systems. A model and taxonomy for IDSs and the technologies behind intrusion detection is presented.

Today, many problems exist that cripple the usage of intrusion detection systems. The decreasing confidence in the alerts generated by IDSs is directly related to serious problems like false positives. By studying IDS technologies and analyzing interviews conducted with security departments at Swedish banks, this thesis identifies the major problems within IDSs today. The identified problems, together with recent IDS research reports published at the RAID 2002 symposium, are used to recommend the future direction of commercial intrusion detection systems.

Abstract:
La thèse a pour objet l’analyse des déterminants de l’adoption des systèmes de traçabilité dans l’agro-alimentaire français et de ses interactions avec l’organisation des firmes. L’adoption des systèmes informatisés de traçabilité (SIT), basés sur des technologies de l’information et de la communication (TIC), dépend de la structure des organisations, mais entraine aussi des changements dans les organisations. La thèse offre tout d’abord une revue de la littérature économique s’intéressant aux systèmes de traçabilité, à l’adoption des TIC et au changement organisationnel. Elle propose ensuite une analyse empirique, sur données d’entreprises, de leurs interactions autour de trois éclairages. La première partie explore les déterminants micro-économiques de l’adoption des SIT à la fois pour les firmes de l’agro-alimentaire français et ses spécificités comparativement aux autres secteurs industriels en France. La seconde partie analyse les rôles respectifs de la structure des organisations et des changements organisationnels dans le processus d’adoption des SIT. Dans cette étape, on met en évidence que l’adoption des SIT est fortement explicative de l’intensité de changement organisationnel pour les firmes agro-alimentaires. Enfin, nous analysons les implications des systèmes de traçabilité dans les relations inter-entreprises avec une étude sur l’amont de la filière viti-vinicole. Le résultat principal est de montrer que l’adoption des SIT n’est pas seulement une réponse stratégique des firmes aux pressions de leur environnement, réglementaire et marchand, mais aussi un outil de gestion interne associé à un processus de changements organisationnels
The main objective of this thesis is to analyze the determinants of traceability systems adoption and their interactions with the organization of agro-food firms. The adoption of traceability systems based on information and communication technologies (ICT), i.e.electronic traceability systems (ETS), depend on the structure of organizations, but also associate adjustments, thus changes, to the organization. First, we review the economic works of traceability systems, ICT adoption and organizational change, and propose three empirical analyses on how these concepts are interrelated. The first explores the firm-level determinants of ETS adoption of both French agribusiness and the entire French industrialsectors. The second shows the respective roles of a firm’s organizational structure and that of organizational changes in the process of ETS adoption in agribusiness; we highlight that the adoption of ETS increases the intensity of firm-level organizational changes in agribusiness. Finally, we explore the inter-firm implications of traceability systems in the wine-grape supplychain. We consider the adoption of ETS to be not only a strategic reaction of firms tochanges in their external environment, mainly the demand of public authorities and markets,but also an instrument for the internal management of firms, which requires complementary organizational practices

Within the Aerospace industry, the operational community is facing staff reductions, reduced skill levels, and greater complexity of space assets and space missions. This combination requires that techniques be developed that more efficiently interface a human operator with a complex computer system. Operational support of complex space systems will be greatly facilitated by better presentation of information. The presentation and distribution of complex data must evolve towards formats that are easily and naturally embraced by our sensory systems. Some of the information technologies/techniques that facilitate the presentation of complex dynamic graphical data fall into a category called integrated media. The cost of implementing integrated media (IM) architectures has decreased substantially within in the past five years. While implementation costs continue to recede, the quality and value of information that can be presented using IM technologies continues to improve. Today's IM architect can select a variety of components including digital interactive video, 3D Navigable Worlds, Multimedia Authoring Systems, standardized compressors for IM data, low cost high volume storage systems, and operating system extensions for temporal data management. Together, these components form a solid foundation for the development of a variety of compelling IM architectures. Existing satellite support and mission data processing architectures typically present tabular data for assessment. Some "advanced" systems include 2D graphical projections of the data. System experts are generally trained to correlate relationships between tabular data items. The training required to "learn" these complex relationships is tedious and time consuming. This complexity impedes productivity and as space systems increase in sophistication, these techniques for data assessment are quickly becoming antiquated. The development of a prototype decision support system explores the utility of an integrated media documentation system as part of a full-featured decision support architecture for satellite operations.

Abstract:

A modern home contains varieties of electronic equipment and systems like: TV, Hi-fi equipment, central heating systems, fire alarm systems, security alarm systems, lighting systems etc. Enabling these devices to communicate is the first step towards the long-predicted smart home, but this requires communication standards to follow. It can be anticipated that the technology must be wireless in order for such network to be feasible.  Large set of standards are present for as well wired as wireless communication in between such devices, but today no standard communication interface available.

 

The goal of this project is to survey available standards for short-range wireless communication, and to evaluate and compare their capabilities to become a general standard for home automation. The evaluation must take such aspects as security, range, network architecture and the heterogeneous set of devices into consideration. Furthermore, this thesis proposes how to interconnect the home network to the external network for remote supervision and control.

Abstract:
AbstractBackground: In an applied engineering field like requirements engineering, the final goal of the research is its adoption by industry. For technology transfer to be possible practitioners need strong evidence for a technology’s applicability and possible benefits. Therefore research on a technology should be done in a realistic setting so that practitioners can use the results to build a strong case for its adoption. Quality requirements are constraints placed on the software. Empirical results show challenges in handling quality requirements, e.g. include late discovery of quality requirements. In addition, we lack technologies that can be used to incorporate them into the final software. Functional and quality requirements differ in nature; treatment given to functional requirements will not always be applicable for quality requirements. Therefore practitioners need decision support material based on empirical evidence to incorporate the suggested technologies.Objective: The purpose of the thesis is to identify technologies for quality requirements that have been empirically evaluated. Methods in relation to elicitation, specification, metrics (or measurement) and testing will be identified with the aim of providing decision support material to practitioners for incorporating quality requirements in the software. To find possible future directions of requirements engineering research, the current state of technology adoption for quality requirements will be identified. Method: The presented research is explorative and investigative in nature. A systematic literature review method was employed to identify potential technologies for adoption. An empirical study was conducted with three participants from three companies to get an insight into the state of technology adoption. Results: The systematic literature review includes 46 papers published between 2000 and 2010. All in all only four of the 46 papers offer high realism and support for technology adoption, i.e. presenting evaluations in a realistic setting, with practitioners using real world industrial applications. Another three papers were found to have potential in terms of furthering technology transfer. A general finding common for many of the papers reviewed is a lack of scientific rigour which affects the credibility of the results. Among the participants in the three companies interviewed, none of the methods presented were used. Conclusions: Technology transfer support for quality requirements technologies is challenged by low strength of evidence. Evaluations of technologies lack descriptions of evaluation design - description of how evaluations have been performed - and validity. There is a need for more and better empirical evaluations of technologies to handle quality requirements. The results of industrial interviews shows the need for more empirical investigations, for example surveys, to identify current industrial practices and technologies able to handle or incorporate quality requirements in projects successfully.

Abstract:
This investigation focuses on configurable technologies, a term which refers to technologies that are highly parameterizable and are built from a range of components to meet the very specific requirements of a particular organization. They cannot be seen independently of their representations through external intermediaries who "speak" for the technology by providing images, descriptions, demonstrations, policies, templates and "solutions". I use the term technology-configuring mediation to refer to the process characterized by a socially constructed relationship between clients and consultants, where visions of how the technology should operate are negotiated. Configurable tools are well illustrated by ERP projects and represent an important trend in IS, drawing its popularity from the hope of benefiting from increased economies of scale and access to cumulative knowledge supposedly "embedded" into these technological artifacts.
From a critical interpretive perspective that combines ideas from structuration theory, social shaping views of technology and critical discourse analysis, this dissertation is based on an empirical investigation that spanned one year and is primarily organized in three papers. The first paper investigates the use of structuration theory in the IS field, asking: How can we successfully apply structuration theory in IS empirical research? Paper 1 contributes to the advancement of interpretive research methods by describing, analyzing and illustrating the ways IS scholars have used Giddens' theory in their research. In addition, it presents a repertoire of research strategies that may help overcome barriers to the empirical application of structurationist theory by dealing with three core elements: time, context and duality of technology.
The second paper discusses the rhetorical closure that often dominates discourses about IT, arguing that configurable technologies are social constructions and, to different degrees, are always open to change. Taking ERP projects as a typical illustration of configurable IT, Paper 2 describes a multilevel framework that identifies occasions for ERP package negotiation and change at three levels---segment, organization and individual---thereby breaking down the rhetorical closure that seems to dominate public debate. Paper 2 draws on structurationist and political streams of thinking about technology to set out a theoretical framework that contributes to advancing our knowledge of configurable IS phenomena.
The third paper addresses the question: How does the mediation process influence the negotiation between global principles and local contexts during the implementation of configurable IS, and how does such a negotiation influence the success of the implemented technology? Paper 3 provides a new understanding of configurable technology implementation. The structuring of a new configuration is seen as a mediation process where knowledge and power dependencies are created and recreated over time by consultants and clients, the entire process being bordered by internal and external constraints. Paper 3 recognizes different patterns of mediation and explains how these patterns affect the negotiation of global principles and local contexts as well as the project results. The study ends by identifying a collection of mediating strategies that are likely to improve the implementation of configurable IS.

Abstract:
Information Technology (IT) has been put forth as a reasonable way to sustain visitor interest and encourage visit repetition in museums. Therefore, IT is becoming more common in museum settings and professionals express their need for more information about how their visitors interact with these systems. This dissertation is an attempt to answer this call. We propose three essays that deal with different aspects of museums and IT from a user-centered perspective. The first essay is an attempt to determine with a free simulation experiment how IT and more particularly websites can arouse interest for museological content. The second essay relies on a field study to analyze the influence of IT on affective and cognitive reactions during a museum visit, namely perceived enjoyment, perceived authenticity and learning. In the third essay, we use focus groups and questionnaires to explore visitor expectations towards a phenomenological experience and the role played by IT in visitor experience of the past. This dissertation contributes to research by (1) advancing our knowledge of IT dedicated to the cultural heritage area, and (2) identifying and understanding visitor perceptions of hedonic systems. By proposing a set of key dimensions that could be used for IT evaluation in the cultural heritage, this dissertation also offers actionable advices to museum professionals.

Abstract:
Small business owners in a range of industries continually adapt to take advantage of technological developments in accounting, marketing, and communication. The purpose of this multiple case study was to explore strategies that small business owners operating in the central region of North Carolina used to implement information and communication technology (ICT). Roger's diffusion of innovation theory grounded the study. Data collection included face-to-face semistructured interviews with 6 owners of small businesses who successfully implemented ICT, field notes from site observations, and reviews of participant websites. Interviews were transcribed and participants were engaged in member checking. Data were analyzed using Yin's 5-step process, methodological triangulation, and manual coding methods. Three themes emerged: applications, security awareness, and overcoming barriers. The study findings might be of use to owners of small businesses for improving business processes, customer satisfaction, and cost savings. This study might contribute to social change by increasing the sustainability of small businesses in the community, which could drive economic development and improve community relations. Potential implications for effecting positive social change include increasing the rate of small business owners' success in e-commerce and Internet technologies, and increasing the financial security for owners, employees, their families, and communities.

Full text
Abstract:
Existing digital heritage systems accommodate a huge amount of digital repository information; however their content rendering and interaction components generally lack the more interesting functionality that allows better interaction with heritage contents. Many digital heritage libraries are simply collections of 2D images with associated metadata and textual content, i.e. little more than museum catalogues presented online. However, over the last few years, largely as a result of EU framework projects, some 3D representation of digital heritage objects are beginning to appear in a digital library context. In the cultural heritage domain, where researchers and museum visitors like to observe cultural objects as closely as possible and to feel their existence and use in the past, giving the user only 2D images along with textual descriptions significantly limits interaction and hence understanding of their heritage. The availability of powerful content rendering technologies, such as 3D authoring tools to create 3D objects and heritage scenes, grid tools for rendering complex 3D scenes, gaming engines to display 3D interactively, and recent advances in motion capture technologies for embodied immersion, allow the development of unique solutions for enhancing user experience and interaction with digital heritage resources and objects giving a higher level of understanding and greater benefit to the community. This thesis describes DISPLAYS (Digital Library Services for Playing with Shared Heritage Resources), which is a novel conceptual framework where five unique services are proposed for digital content: creation, archival, exposition, presentation and interaction services. These services or tools are designed to allow the heritage community to create, interpret, use and explore digital heritage resources organised as an online exhibition (or virtual museum). This thesis presents innovative solutions for two of these services or tools: content creation where a cost effective render grid is proposed; and an interaction service, where a heritage scenario is presented online using a real-time motion capture and digital puppeteer solution for the user to explore through embodied immersive interaction their digital heritage.

Abstract:
This thesis aimed to study the everyday use of ICT-enabled memory aids in order to understand and to describe the technological mediations that are brought by them (i.e. how they shape/mediate experiences and actions of their users). To do this, a post-phenomenological approach was appropriated. Postphenomenology is a modified, hybrid phenomenology that tries to overcome the limitations of phenomenology. As for theoretical framework, ‘Technological Mediation’ was adopted to conduct the study. Technological Mediation as a theory provides concepts suitable for explorations of the phenomenon of human-technology relation. It was believed that this specific choice of approach and theoretical framework would provide a new way of exploring the use of concrete technologies in everyday life of human beings and the implications that this use might have on humans’ lives. The study was conducted in the city of Växjö, Sweden. Data was collected by conducting twelve face-to-face semi-structured interviews. Collected data was, then, analyzed by applying the concepts within the theoretical framework – Technological Mediation - to them. The results of this study provided a list of ICT-enabled devices and services that participants were using in their everyday life in order to support their memory such as: calendars, alarms, notes, bookmarks, etc. Furthermore, this study resulted in a detailed description of how these devices and services shaped/mediated the experiences and the actions of their users.

Based on the empirical analysis of the terrorist activities, we can say that developed and globalized countries are more safer than the developing countries. The terrorist attacks are considerably low in these countries.To analyze the role of new technologies in terrorism and the actual use of ICT in terrorism, I have focused on the terrorist groups operating in Pakistan. These groups are taking advantage of these technologies in many ways like, Recruiting, Propaganda, Fund raising etc.Answer to the question of Islamic terrorist threat to the West again based on the empirical analysis. The analysis shows that Islamic terrorism is on continuous decline. Islamic terrorist groups are involved highly in other countries, especially Muslim majority countries. The analysis also showed that there is very less impact of the the new technologies on Islamic terrorism.

Abstract:
Information Literacy is an integral part of university libraries. At the University of Cape Town (UCT) it has had varying levels of success, depending on the size of the class, the access to devices, the time provided, and the frequency of sessions. Unlikely other universities around the world, information literacy is not embedded in the curriculum. The standard practice in our context has been once-off sessions offered to students at the beginning of an academic year. This is targeted to different courses and disciplines. This study sought to understand the information (IL) and digital literacy (DL) skills of postgraduate students in an Information Systems (IS) course. Specifically it looked at how they undertake their academic writing tasks without formal exposure to IL or DL training. It examines the general IL and DL skills, the ineffectiveness of IL interventions provided and explores opportunites for curriculum integration of Il in postgraduate courses. This case study uses a case study approach to explore the perceptions of students and their lecturers of the IL presentations which the library offers. Using a mixture of interviews with lecturers and a student questionnaire and focus group discussions with students the study sought to provide a wholistic picture of the various perspectives and experiences. Findings showed that students and lecturers had a very narrow perception of IL, although IL is a skills set that helps students to acquire competencies for a lifelong learning journey in terms of information usage generally and digitally in particular. A framework for librarians is proposed based on SCONUL's Seven Pillars of Information Literacy. This would enable a more wholistic approach to IL as it develops student as self-directed learners rather than learners who just aim to comply with course regulations. Integration of IL into the curriculum is proposed as a necessary strategy and if librarians increased their teaching professionalisation working in partnership with their academic colleagues, they could raise the profile of IL in institutional priorities.

Full text
Abstract:
Information and Communication Technologies (ICTs) are becoming increasing relevant in policy making and governance activities. However, the broad effects of digital governance have not been adequately conceptualised; conflicting assumptions vary from rather optimistic accounts of empowered citizens to even completely dismissing the potential of engagement through technical means. This research attempts to reposition the impact of ICTs on policy making and political communities. Drawing from institutional studies, an integrated perspective is synthesised to guide case investigations in three main directions: (1) the way influences from the institutional environment are understood and balanced locally, (2) the co-evolution of institutional and technological configurations and (3) the dynamic response of institutional actors to the challenge of online engagement. The empirical part focuses on two different contexts (local government authorities and a trade union federation) that cover the holistic objective of this study. The findings inform on the extent to which ICTs are actually merging with existing governance structures. Both studies show that policy making is fundamentally different from other activities at the general intersection of Internet and politics. Citizens form online communities to organise ad hoc around single issue movements. However, this does not necessarily translate into sustainable and meaningful participation in formal politics. Hence, adapting institutional structures emerges as a complicated challenge beyond fitting technical means into existing engagement activities. On this basis, the thesis questions the extent to which policy making mechanisms are able to enact engagement from the grassroots, as for example encouraged by the social media collaboration philosophy. Implications for practice show how the alignment between new tools and the existing norms has the potential to identify paths of least resistance, and then exploit them to accomplish positives changes whose beneficial effects should not be taken for granted.

Abstract:
The Semantic Web enables people and computers to interact and exchange information. Based on Semantic Web technologies, different machine learning applications have been designed. Particularly to emphasize is the possibility to create complex metadata descriptions for any problem domain, based on pre-defined ontologies. In this paper we evaluate the use of a semantic similarity measure based on pre-defined ontologies as an input for a classification analysis. A link prediction between actors of a social network is performed, which could serve as a recommendation system. We measure the prediction performance based on an ontology-based metadata modeling as well as a feature vector modeling. The findings demonstrate that the prediction accuracy based on ontology-based metadata is comparable to traditional approaches and shows that data mining using ontology-based metadata can be considered as a very promising approach.

Abstract:
This thesis has its starting point in the digitalization of society focusing on the rapid development of mobile technologies and the increasing interplay between humans and machines. The use of information and communication technologies (ICT) is extending at a fast pace, affecting all parts of society, and the everyday life of most individuals. The fast progressing development of mobile technologies (smartphones and their accessories/ wearable’s) is creating new trends such as health tracking and quantified self. These mobile technologies can register an increasing number of physiological features, implying that the interconnection between the physiological and digital systems is increasing. This creates a range of new possibilities within health and medical research but it also creates new challenges and the need for new knowledge in how we relate these devices to our bodies. In the psychological perspective, smartphone use is increasing and previous studies imply that these devices are affecting our behaviour, our mental health as well as our cognitive functions. This implies for a need to understand the relation we have to these devices also in a psychological perspective, focusing on emotions and cognition. This study set out to explore the relation between humans and technologies from a systems perspective. The research question involved: How are users and smartphones related in physical and psychological perspectives? The methods used were questionnaires and interviews. The respondents were students in two European universities, who described their experiences of smartphone use, and three doctors (in medicine and biomedicine) that provided interesting aspects in how mobile technologies can be related to the human body from a system perspective   In a physical perspective the users as well as their physical environments could be described as converging with the digital systems. The need of being connected and have access to all life-spheres at once seemed to be an important driving force, implying that users are dependent on information and a converged life-style. In a psychological perspective, the emotional bond seemed stronger then the actual physical need. The perceptions of smartphones differed, but a common denominator described by both Swedish and Albanian users, was the perception of the smartphone as something with human-like features, comparable to a friend. The last part of the study concerned if smartphones can be seen as a new entity of our own system, comparable to an organ. The result suggests that this depends on the individual use, if the technologies is used to sustain health, the value it provides, and it is also a matter of the users ontological believes. The concept of physio-digital convergence is proposed as a new concept to analyse the development of increasing use of mobile technologies further.

Abstract:
Public safety is negatively affected when arrest warrant information is not available to law enforcement officers, judges, prosecutors, and other criminal justice practitioners. The U.S. Government and the criminal justice community have advocated for electronic warrant systems (e-warrants). Peace officers know that when e-warrant systems deliver warrant information to them immediately from multiple jurisdictions, their safety is increased. However, the factors that cause these e-warrants systems to improve safety are not known. The purpose of this historical data analysis study was to determine if the use of e-warrant systems resulted in shorter clearance times than the use of legacy paper-based systems. Stakeholder theory, open systems theory, and service-oriented architecture theory were used to guide the quantitative research design. This study compared 2 years of historical arrest warrants from 6 sheriffs' departments organized into population matched sets. Two-way ANOVA tests and nonparametric tests were conducted to analyze the impact of the independent variables warrant system type and case type on the dependent variables mean service days and percent warrants served. The study showed that operating e-warrant systems in similar size sample agencies did not ensure shorter mean service days and higher percent warrants served over legacy systems, and it confirmed that more research is needed to determine other factors that will lead to an improvement in these variables. The findings of this study may assist agency executives and justice practitioners to identify other variables that may increase effectiveness of e-warrant systems, thereby improving public and officer safety, both important social benefits.

Abstract:
Mobile technologies are emerging as one way to help address health challenges in many countries, including in Least Developed Countries. Mobile technology can reach a large share of the population but in order to provide effective support to healthcare services, technology, information collection and dissemination, and work processes need to be well aligned. The thesis uses a design science methodological approach and mixes qualitative and quantitative data analysis to address the question of, How can mobile technologies be effectively integrated with routine healthcare services? The study concerns the design, implementation, and evaluation of a mobile technology-based system, called SMSaúde, with the aim of improving the care of patients with HIV/AIDS and tuberculosis in Mozambique. The work started with the elicitation of functional and user requirements, based on focus group discussions. An important challenge, as in many mHealth interventions, was the integration with routine healthcare services and the existing IT systems, as well as developing a scalable technical structure. The system has now been in routine use since 2013 in more than 16 healthcare clinics in Mozambique. Evaluation was done by a randomised controlled study. Analysis of patient records showed that retention in care in urban areas was significantly higher in the intervention group than in the control group. In a user study both patients and health professionals were very positive to the system. The thesis contributes to research by demonstrating how information system artefacts can be constructed and successfully implemented in resource-constrained settings. The practical contributions include the designed artefact itself as well as improved healthcare practices and mHealth policy recommendations.

Abstract:
Récemment, avec les progrès technologiques rapides que nous observons dans le domaine des Technologies de l'Information et de la Communication (TIC), de nombreux Systèmes d'Information (SI) sont introduits dans nos vies à la maison ou au travail. Cela entraînera des défis croissants pour les utilisateurs, tels que la nécessité de gérer d'énormes quantités de ressources et la difficulté de collaborer avec les autres. Afin de trouver la bonne information au bon moment pour prendre des décisions éclairées, les utilisateurs doivent rechercher des ressources réparties dans de nombreux SI (courriels, réseaux sociaux, pages wiki, notes électroniques, etc.). Le processus de recherche de ressources dans différents SI est coûteux et prend du temps; il doit donc être optimisé. L'émergence des Écosystèmes Numériques (DE) offre aux utilisateurs le potentiel d'améliorer l'accessibilité et la coordination des différents systèmes.D'autre part comparable à un DE, un système de systèmes d'information (SoIS) est composé de SI intégrés qui sont hétérogènes et fonctionnent indépendamment de manière autonome, mais qui sont mis en réseau pour un objectif commun.L'objectif mentionné précédemment, pourrait être l'organisation et le partage de ressources hétérogènes. Cette thèse se concentre sur le passage des Écosystèmes Numériques à un système de systèmes d'information en tant que solution aux défis émergents auxquels sont confrontés les utilisateurs de différents SI dans un contexte de collaboration. Le SoIS donne l'occasion d'explorer comment la collaboration peut être améliorée grâce à une combinaison de différents SI dans l'environnement numérique des organisations. Dans ce contexte, nous avons défini un modèle sémantique et un modèle architectural de SoIS. Nous avons ensuite développé un prototype, appelé MEMORAeSoIS, basé sur ces modèles comme support de collaboration. Ce prototype peut offrir la possibilité d'indexer, de partager, d'annoter et de recommander des ressources importantes provenant de différents SI

Abstract:
It is difficult to learn professional courses such as Computer Science without hands-on activities with appropriate technical support. Computer Science programming courses are the core of a Computer Science qualification and some of the learning outcomes of a Computer Science programming course are writing program code, program testing and debugging. Inadequate computers in the computer laboratory and policies that restrict the concept of 'Bring Your Own Technology' (BYOT) inside the computer laboratory posed a challenge to hands-on programming activities. However, students in the Computer Science department at the University of Jos learn computer-coding theory, but unable to have hands-on experience due to several reasons. This research investigates how use of virtual lab on Moodle Learning Management System (LMS) could enhance students' acquisition of Java programming skills. The virtual lab provides a lab environment for students to practice programming and experiment concepts learned. Activity Theory was used as a theoretical framework to analyse the activity of Java programming on the virtual lab. Seven participants including the lecturer were enrolled on the Java Programming Language virtual lab practical sessions for this research work. The research activity system focuses on Java hands-on programming tasks for a period of three weeks and after that data was collected using interview and content generated from the virtual lab activities' chats and forum. Interview questions were developed and administered to students, while a semistructured interview with the lecturer was conducted. The data collected from the interviews and the contents collated from chats and forum activities were coded using ICT data analysis tool Nvivo, based on thematic analysis. The data was thoroughly reviewed, explained, interpreted, and analysed using the theoretical framework, activity theory. The results show that the virtual lab helped students perform practical programming activities, where students accessed and used the virtual lab concurrently at any time and place. The participants used their private computers, mobile devices in the hostels, at home, or at hotspots to access the virtual lab. However, accessing the virtual lab required adequate Internet connection. The virtual lab programming activity system promoted student-centred learning, self-paced practice, and enabled students to repeat or revisit incorrect assignments multiple times. The activity system's subject (lecturer, students) interacts with the mediating tools (mobile devices, virtual lab) to perform the object (Java programming), which enhanced the achievement of the outcome (programming skills). Therefore, it can be said that the virtual lab mediated hands-on programming activities.

Abstract:
Today's organizations face an economic climate that is globalizing, increasing customer demands for products and services that meet their unique needs and the fast pace of technological developments. Organizations require the effective use of new communication technologies as a means of sharing information and expanding capacity for innovation. The main question for this research is: When new communication technologies are introduced into organizations, how do they work together with existing cultural assumptions to produce an innovative, learning environment within the organization? The research design involves conducting moderately structured interviews with organizational leaders in four diverse organizations: Ingram Book Company, Service Merchandise Company, Inc., Life Way Christian Resources of the Southern Baptist Convention, and Dollar General Corporation. Results include an introduction to each company, a report on their implemented new communication technologies and innovative learning environment, and a description of their core corporate culture.

Abstract:
Today's workforce demands the ability to multi-task. Enterprise Resource Planning (ERP) aids businesses by attempting to integrate all departments and functions across a company to create a single software program that runs off one database. An investigation of ERP and supporting technologies was conducted to determine if organizations utilized the full potential of the systems they installed. The researcher investigated companies that have installed ERP systems, and with the use of an online survey, determined the extent to which the companies utilized the full potential of the systems. The study was also conducted to learn the best practices that can be used in ERP system implementation, system maintenance, system expansion, and related activities to recommend to individuals and organizations that can benefit from the research. A link to an online questionnaire was sent to ERP end-users and implementers via email. This mode of distribution was the most efficient because survey participants were able to access the questionnaire in real time and the researcher was also able to retrieve the responses instantaneously. The responses were retrieved and recorded in an Excel database and pivot tables were used to analyze the data. The data collected from 18 different types of businesses revealed 8 major software packages, over 80% of the organizations sponsored end-user training, and the impetus for implementing ERP focused on three unanimous reasons: reduced cost, increased productivity, and increased efficiency. While the responses were fewer than anticipated, the results supported the researcher's hypothesis that ERP systems are typically not fully utilized to their full potential. The researcher noted that 60% to 70% of the ERP systems installed were underutilized. This was determined by calculating the percentage of ERP modules utilized in a single system versus the total available modules that can be fully utilized. Additionally, the research literature supported the hypothesis that the underutilization of an ERP system compromises its anticipated benefits and does not support the null hypothesis that there are no significant relationships among technologies (project management, business process re-engineering, and customer relationship management) used to develop and support the utilization of ERP systems.
