Over the past decade there has been a dramatic increase in the volume of digital content created from museum, library and archive collections but research on how this material is actually used, particularly in digital learning environments, has fallen far behind the rate of supply. In order to address this gap, this thesis examines how communities of practice (CoPs) involved in the supply and use of digital artefacts in the Higher Education sector in the UK interact with content and what factors affect this process. It focuses on a case study involving the digitisation of Shakespeare collections used in postgraduate research, and the testing of use in a range of different learning environments. This produced a number of significant findings with implications for the HE and cultural sectors. Firstly, similar patterns of artefact use were found across all users suggesting there are generic ways in which everyone interacts with digital artefacts. However, distinct forms of use did emerge which correspond with membership of particular communities of practice. Secondly, members of a CoP appear to share a particular learning style and this is influenced by the learning environment. Finally, the research indicates that a mixed method for analysing and measuring use, piloted and tested in the case study, is possible.

At present, the average employee is being bombarded with an ever-increasing number of messages information on his/her company, its products and services, as well as information on its strategy all flooding in from a myriad of sources, including internal vehicles such as e-mail, the intranet, management memoranda, internal publications, as well as the external media, such as the Internet, the local newspaper, television news and national business and industry magazines. The term “information overload” is usually understood to present a state of affairs where an individual’s efficiency in using information in his/her work is hampered by a surplus amount of relevant and potentially useful information available to him/her. The principal aim of this study, therefore, is to establish the extent and impact of information overload on the knowledge worker in the banking industry, with special reference to the part that e-mail technology plays in the creation of such overload. Broadcasting, the telephone and the Internet have revolutionised the way in which workers communicate around the globe. Electronic-messaging systems such as e-mail have become the medium of choice in many organisations, and hold significant and valuable business data, information and knowledge. These systems have had a profound impact on the way in which personal and business communications are effected in the office. With e-mail having acquired mission-critical status, a number of concomitant circumstances and consequences have arisen that present organisations, such as banks, with a variety of challenges, among which • the impact on employees’ productivity, owing to the time spent on e-mailing activities • employees’ attitudes towards e-mail • compliance with corporate policies, such as those policies governing electronic communication and computer use • surveillance and monitoring of e-mail • the quest for finding formal archiving solutions. / Prof. C.W.

D.Litt. et Phil. / This study investigated the impact of the Web on the information-seeking and citation behaviour of Unisa academics. The research study was executed in two phases. Phase 1 consisted of a Web citation analysis and phase 2 a questionnaire. Phase 1 explored how the availability of Web information resources affected the scholarly citation behaviour of Unisa academics by determining the relationship between Web-based references and non-Web-based references in the reference lists of Unisa academics. In phase 1 it was established how frequently Web-based information resources were cited (reference lists) compared to traditional print sources. Furthermore, the variation in Web citation patterns between academics from different subject disciplines was identified. The main source of data was 20 825 citations contained in reference lists, endnotes and footnotes of 458 accredited research journal articles submitted in 2004 by Unisa to the Department of Education for subsidy purposes. The data were gathered by calculating the total number of references that appeared in the reference lists. Thereafter a citation count was done of the total number of Web references cited in the article by checking each article for references containing Web-based information resources such as URLs of webpages or websites. Collectively the reference lists consisted of 3.5% references to Web-based information resources and 96.5% to non-Web-based information resources. The findings of the 2005 citation study indicate that academics tended to rely on static, academic library, print-based resources when citing the literature, not Web-based information resources. Furthermore, academics from the five Unisa Colleges displayed different Web citation patterns. Phase 2 of the study, a questionnaire survey, provides insight into the relative significance of the open Web as an information resource and Web search engines as research tools among academics. The aim of the questionnaire was to record the preferences, usage and perceptions of the freely available open Web information resources, as compared to the academic library information resources (print and electronic). In addition, the factors that influence the choice of the academic when iv selecting the open Web or the academic library as an information resource were investigated. The entire Unisa academic staff establishment was invited via e-mail and the Unisa intranet to participate in the survey. The survey instrument consisted of 32 questions via the Web and/or print-based format. The findings reported are based on a survey of 187 Unisa academics with a response rate of 15.74%.

This diploma work focuses on freely available and professional electronic information resources for environmental issues. These resources are only accessible from computer networks (such as the Internet or other digital data distribution networks). The thesis is divided into three parts. The first part defines typical users of such resources in connection with their user needs. In the other two parts freely available and professional electronic information resources for environmental issues are classified and reviewed while several resources are completed with both qualitative and quantitative analyses. This work also contains analyses of resources availability and it is provided with charts and graphs for better understanding of the topic.

Information literacy skills among university students have become a necessity rather than the norm. With the increase of information resources, the need for information skills among university students is important for their continued access to, and retrieval of, information. The purpose of this research was to investigate information literacy skills and competencies among incoming first-year undergraduate students in institutions of higher learning in Kenya, with special reference to the Catholic University of Eastern Africa. The objectives of the study were; to identify the types and formats of resources that incoming undergraduate students are aware of, to determine whether the incoming undergraduates are aware of search strategies for both print and electronic/online resources, to determine whether incoming undergraduate students possess basic information technology skills, to find out whether incoming undergraduate students know information retrieval tools and their use, and to determine whether incoming students are aware of intellectual property and copyrighted materials and their ethical use. The study adopted a quantitative approach and used the case study research method. The study targeted first year incoming undergraduate students at the Catholic University of Eastern Africa for the academic year 2013/2014. 137 incoming undergraduate students participated in the study. Data was collected by using self-administered questionnaires. Quantitative data was coded and analysed by using Statistical Package for Social Science (SPSS). Qualitative data generated form open-ended questions was presented in narrative form under respective subheadings. The finding of the study observed that: (a) Incoming first-year students have limited knowledge of strategies used to search for information. (b) The incoming first-year undergraduate students at the Catholic university of Eastern Africa do possess computer skills in applications such as the use of the internet and its applications (e.g. social networking sites and the World Wide Web) as well as the word-processing applications such as (Microsoft Office and Microsoft Word) and statistical applications such as SPSS. (c) Majority of incoming undergraduate university students are not familiar with the various retrieval tools and their applications. (d) The incoming first-year undergraduate students are familiar with both electronic and printed information resources. (e) A significant number of students were not aware what constitutes primary resources and secondary sources. (f) Incoming first-year undergraduate students exhibited little knowledge of issues relating to intellectual property rights and copyright. Several recommendations have been made based on the findings of the study. One of the recommendations is that the university library mandated with offering information literacy instruction to incoming students should adopt several incentives aimed at encouraging the students to attend library orientation. Another recommendation is to integrate the information literacy training with the normal university curriculum to become a credit-earning course for all incoming students. The university library should also carry out a needs assessment on information literacy training to help determine the existing gaps in the current information literacy programme. The programme should also be tailored to help in emerging issues such electronic plagiarism of information resources. The study further recommends a longitudinal study to determine whether students joining the university are able to gain information literacy skills over a period of time. / Information Science

Text in English, abstract in English and Afrikaans / Information is one of the most important resources in organizations today. The role of Marketing Information Systems (MKIS) is to facilitate the efficient and effective use of information in marketing decision-making. Service organizations are especially reliant on decision-support information, due to the complex nature of their environment. However, indications are that they are not utilizing information to their best benefit, despite the considerable advantages they might gain from it. In fact, it could be said that service organizations often seem to lack a culture of market orientation. In measuring the satisfaction with the quality of market intelligence, it becomes obvious that marketing decision-makers are generally dissatisfied with the results of MKIS. Some of the reasons are: • The 'disconnect' between information technology and marketing in organizations, which results in marketing decision-makers not getting information in the format they require, and feeling as if their requirements are not taken into account when MKIS are developed. • The lack of availability of usable customer and competitor data, which are regarded by marketing decision-makers as the most important categories of information. • The focus on generating data, but not adding value to it. Marketing decisionmakers have indicated that they require analysis, and not raw data. In order to bridge these problems, South African service organizations need to focus on the successful integration of MKIS into the organization. This requires an understanding of marketing decision-makers' requirements, closer cooperation between IT and marketing and the establishment of a culture of information sharing. / lnligting is een van die belangrikste hulpbronne van hedendaagse organisasies. Die rol van bemarkingsinligtingstelsels (BMIS) is die fasilitering van die doelmatige en effektiewe gebruik van inligting in bemarkingsbesluitneming. Diensorganisasies is veral afhanklik van besluitsondersteunende inligting, as gevolg van die komplekse aard van hulle omgewing. Tog is daar aanduidings dat hulle inligting nie tot die beste voordeel aanwend nie, ten spyte van die aansienlike voordeel wat hulle daaruit kan trek. In werklikheid kan dit gestel word dat diensorganisasies skynbaar nie 'n markgerigte kultuur het nie. In die meting van tevredenheid met die kwaliteit van markintelligensie blyk dit dat bemarkingsbesluitnemers in die algemeen ontevrede is met die resultate van BMIS. Sommige redes hiervoor: • Die gaping tussen inligtingstegnologie en bemarking in organisasies, wat daartoe lei dat bemarkingsbesluitnemers nie inligting ontvang in die formaat wat hulle vereis nie, en voel dat hulle behoeftes nie in ag geneem word wanneer BMIS ontwikkel word nie. • Die gebrek aan bruikbare inligting oor kliente en mededingers, wat deur benarkingsbesuitnemers beskou word as die belangrikste kategoriee van inligting. • Die fokus op die genereer van data, sonder om waarde daaraan toe te voeg. Bemarkingsbesluitnerners het aangedui dat hulle ontleding vereis en nie slegs 'rou' data nie. Ten einde hierdie probleme te oorbrug moet Suid-Afrikaanse diensorganisasies fokus op die suksesvolle integrasie van BMIS in die organisasie. Dit vereis begrip vir bemarkingsbesluitnemers se behoeftes, nader samewerking tussen inligtingstegnologie en bemarking en die daarstel van 'n kultuur van gedeelde inligting. / Business Management / D.

When learning mathematics, deaf children of primary school age experience difficulties due to their disability. In Jordan, little research has been undertaken to understand the problems facing deaf children and their teachers. Frequently, children are educated in special schools for the deaf; the majority of deaf children tend not to be integrated into mainstream education although efforts are made to incorporate them into the system. Teachers in the main stream education system rarely have knowledge and experience to enable deaf students to reach their full potential. The methodological approach used in this research is a mixed one consisting of action research and Human Computer interaction (HCI) research. The target group was deaf children aged nine years (at the third grade) and their teachers in Jordanian schools. Mathematics was chosen as the main focus of this study because it is a universal subject with its own concepts and rules and at this level the teachers in the school have sufficient knowledge and experience to teach mathematics topics competently. In order to obtain a better understanding of the problems faced by teachers and the deaf children in learning mathematics, semi-structured interviews were undertaken and questionnaires distributed to teachers. The main aim at that stage of research was to explore the current use and status of the e-learning environment and LMS within the Jordanian schools for the deaf in Jordan. In later stages of this research, semi-structured interviews and questionnaires were used again to ascertain the effectiveness, usability and readiness of the adopted e-learning environment “Moodle. Finally pre-tests and post-tests used to assess the effectiveness of the e-learning environment and LMS. It is important to note that it was not intended to work with the children directly but were used as test subjects. Based on the requirements and recommendations of the teachers of the deaf, a key requirements scheme was developed. Four open source e-learning environments and LMS evaluated against the developed key requirements. The evaluation was based on a software engineering approache. The outcome of that evaluation was the adoption of an open source e-learning environment and LMS called “Moodle”. Moodle was presented to the teachers for the purpose of testing it. It was found it is the most suitable e-learning environment and LMS to be adapted for use by deaf children in Jordan based on the teachers requirements. Then Moodle was presented to the deaf children’s to use during this research. After use, the activities of the deaf and their teachers were used and analysed in terms of Human Computer Interaction (HCI) analysis. The analysis includes the readiness, usability, user satisfaction, ease of use, learnability, outcome/future use, content, collaboration & communication tools and functionality.

This study assesses information-seeking and perceptions of expertise in Electronic Networks of Practice (ENoPs). ENoPs are a particular type of online community focused on sharing information related to a specific work-related profession (Wasko and Faraj, 2005). To date, there has been little empirical work on the dynamics of information exchange in ENoPs (Whelan, 2007). The little we do know is based on face-to-face communities, which cannot be generalized to online interactions due to changes in size, purpose, and method of communication. Understanding the type and perceived value of information is an important line of theoretical inquiry because it has the potential to identify the specific informational needs these communities fulfil and the types of people most likely to fulfil them. This research was conducted in an ENoP focusing on the exchange of information related to the practice of engineering. The community studied, Eng- Tips, is a thriving network focusing on the practice of engineering that has produced over 150,000 posts, and is comprised of engineers from twenty-one different specialties. Interactions take place solely through the use of virtually mediated technology, and focus primarily on practice-related issues. The format of interaction is typically based on a query and a stream of ensuing replies. Data were collected through metrics and a coding procedure that allowed me to identify the most common queries in the ENoP. My data revealed queries in the ENoP tended to focus on obtaining solutions, meta-knowledge, or validation. The high emphasis on validation was similar to that found in face-to-face friendship networks, and was contrary to Cross et al.’s (2001) anticipated results, most likely due to the presence of anonymity. I also found that experience of interacting with multiple specialties (i.e. interactional expertise) was positively associated with perceived expertise. Finally, I discovered that replies, giving out nominations, and frequently logins were positively associated with the number of expert nominations one received in the community. This research makes contributions to both theory and practice. I contribute to theory on information-seeking by extending Cross et al.’s (2001) research to the online environment, and articulating the type of informational benefits sought in the ENoP. I contribute to theory on expertise by exploring the characteristics associated with perceived expertise, and exploring the reasons why interactional expertise may be particularly valued in ENoPs. My work in this area reveals that—in the context of the ENoP studied—a ‘common practice’ is highly fragmented and loosely knit, further distinguishing this entity as a unique organizational form. My findings in this area call into question the validity of a practice-based approach for examining these entities, and for these reasons, I suggest they may be better conceptualized as Electronic Networks of Discourse. Practical ramifications focus on describing the type of information members want to obtain from their involvement in the community, which may benefit members, organizations, and managers of the ENoP.
