An exploratory study of government ministerial libraries in Maseru, Lesotho.

Keta, Mary Manthati. January 2004 (has links)
The present study explores the status of government ministerial libraries in Maseru, Lesotho, with the purpose of discovering the factors which affect the growth and development of these libraries. To provide a wider context within which to view this study literature dealing with government libraries was examined. Nineteen government ministerial libraries were chosen as a population for the study. However, only fourteen ministerial libraries were eventually surveyed. Twenty library workers were interviewed using a structured questionnaire as the data collection instrument. The collected information was analysed manually. The study established that there are very few laws and regulations that govern the existence of libraries in Lesotho. The responses showed that even though there are government ministerial policies they do not accommodate libraries. The majority of these libraries do not get support from government for library material and therefore they depend only on donations which are not adequate, most of the time, for the needs of the users. The responses also revealed that the majority of government libraries do not function in the way that fully-fledged libraries do. The library workers revealed that the educational standards of library workers in Lesotho are not satisfactory at all. Among the staff of government libraries that were interviewed only five had a university degree, two had a university diploma and two had university certificates. It was found that some of the library services had not performed well becasue of one-man libraries and a lack of qualified staff The responses from the interviews established that government ministerial libraries in Lesotho are static; they do not grow and develop largely out of a lack of recognition, a lack of interest and a lack of upport from the government. Recommendations are based on the findings of the study with the hope that they will provide a basis for properly equipped and adequately staffed library services in all ministries in future. / Thesis (M.I.S.)-University of KwaZulu-Natal, Pietermaritzburg, 2004.

Establishing criteria for evaluating health-related World Wide Web sites

Chamness, Brenda E. January 1998 (has links)
The problem of the study was to establish valid criteria for evaluating health-related World Wide Web [WWW] sites. From a table of specifications, a pool of 39 items was developed into a Criteria List. A nine member jury of experts composed of professionals from the discipline of Library and Information Science was used to determine content validity of the items. The items on the Criteria List were sent to the expert panel of jurors for the first review. To determine which items would be retained, revised or eliminated, the items were subjected to both a quantitative and qualitative review. The revised Criteria List was then sent to the expert panel of jurors for the second review. Responses from the second review were also subjected to qualitative and quantitative analysis. However, this time the quantitative review included the use of the Content-Validity Ratio [CVR]. All items on the Criteria List that were not statistically significant at p <.05 were eliminated. The final Criteria List contained 27 items from the 39 originally proposed items. / Department of Physiology and Health Science

Web-based information behavior of high school learners in Oshana region, Namibia.

Shiweda, Tertu Ponhele. 22 May 2014 (has links)
The aim of this study was to investigate the Web-based information behaviour of high school learners in Oshana Region in Namibia. The study also considerd the challenges faced by learners when searching the Web for information. For many years in the history of library and information services, print-based information had been the main source of information. However, since the emergence of the Internet and its rapid development, the Internet has provided an almost unlimited pool of Web-based resources, thus becoming a powerful source of information. The Web is now established as the main medium for the wide dissemination of information across the Internet. Within the academic context learners throughout the world are able to retrieve seemingly endless volumes of information across all disciplines and from all over the globe. It is therefore important to study the behavior of young people in relation to Web-based information because it is today one of their most important sources of knowledge. The findings of this study could assist in curriculum design, especially with regard to Basic Information Science (a subject offered in schools in Namibia), which incorporates information literacy and information-seeking skills development. In addition the study provides some insight into the information and computer literacy levels of learners and proposes ways of responding to these, thus assisting in further developing these important literacies. The study was guided by Wilson’s (1999) model of information behaviour. The model attempts to describe an information-seeking activity and suggests relationships among stages in information-seeking behaviour. The study has adopted a quantitative approach as its methodology. Data from a total of 160 respondents was collected using a questionnaire that consisted of both open ended and closed questions. The study’s research questions investigate how, where and when do Grade 12 learners access the Internet, for what purposes do Grade 12 learners use the Web when looking for information, how do Grade 12 learners search for information on the Web, what are the Web information searching skills of Grade 12 learners, what sources of information on the Web do Grade 12 learners use, how do Grade 12 learners evaluate and use information found on the Web, and what are the challenges faced by Grade 12 learners when searching the Web for information. The survey concentrated on Matric learners (grade 12) from Mweshipandeka HS and Gabriel Taapopi SSS in the Oshana region of Namibia. The results were analysed using SPSS as a tool for data analysis. An interpretation of the findings of this study shows that learners Web-searching skills are inadequate. Overall, there was a high level of familiarity with various Web-information sources such as search engines, although users limited themselves mainly to a few sources such as the search engines Google and Yahoo and the online encyclopedia, Wikipedia. Learners were not aware of Google's limitations and of the existence of academic, often library-funded, information sources such as databases and electronic journals. The present study found strong indications that grade 12 learners lack information-evaluation skills as well as acknowledgement skills and that they are not aware of what constitutes plagiarism. This appears to be a result of poor training in schools. However, the status of learner’s access to the Internet is good. Both schools involved in this study provide learners with physical access to the Internet. / Thesis (M.I.S.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

The information needs and information-seeking behaviour of community library users in Msunduzi branch libraries, Pietermaritzburg.

Moodley, Tracy Ann. 27 May 2014 (has links)
The purpose of this study was to identify the information needs and information-seeking behaviour of community library users in Msunduzi branch libraries, Pietermaritzburg. Identifying the information needs and information-seeking behaviour of community library users in the Msunduzi branch libraries helped to determine whether the Msunduzi branch libraries met their needs or not. The study involved a quantitative investigation into the information needs and information-seeking behaviour of community library users in Msunduzi branch libraries, within the context of community information and community information services. The study adopted a descriptive cross-sectional survey design. The instrument used for collecting data was the self-administered questionnaire. The instrument consisted largely of closed questions and a few open-ended questions. A sample of 200 registered members of Northdale, Woodlands, Eastwood and Sobantu Libraries was surveyed, with 196 respondents giving a response rate of 98%. The validity and reliability of the instrument were established by pre-testing the questionnaire with ten community library users at Georgetown Branch Library. The data was captured onto the computer via Microsoft Excel. The data was then tabulated, and then appropriate analysis was conducted on each question’s data. These were presented in the form of graphs. The community library user’s information needs and information-seeking behaviour was identified using Wilson’s second 1981 model of information behaviour which suited the group under study. The results of the study indicated that the demographic and socio-economic status of the four communities influenced the information needs and information-seeking behaviour of the users. It is evident that in all four communities the information needs of the users were basically related to personal existence, survival and development. In terms of information-seeking behaviour, it can also be concluded that the community library users often used the information providers and information sources which they knew best or those which where the most convenient. Barriers experienced by the respondents were insufficient and relevant materials in the libraries and the lack of internet access. Based on the findings, recommendations were made to address certain problems presented in the study. / Thesis (M.I.S.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

Information dissemination for adaptation to climate change and variability in the agriculture sector : the case of Malunga and Chibelela villages, central Tanzania.

Elia, Emmanuel Frank. January 2013 (has links)
This study investigated how access to and use of agricultural information contributed to farmers’ adaptation to climate change and variability in the semi-arid Maluga and Chibelela villages of central Tanzania. The major research problem this study sought to address was how information on adaptation to climate change and variability is packaged and disseminated to farmers. Specifically, the study 1) identified the Climate Change Adaptation in Africa project goals of disseminating information to farmers on climate change and variability; 2) assessed the status of knowledge adaptation to climate change and variability by farmers; 3) determined farmers’ access to, and use of, information on climate change and variability, and 4) investigated factors affecting access to, and use of, information on adaptation to climate change and variability by farmers. The study was underpinned by Rogers’ Diffusion of Innovations Model. A post-positivist approach was used, with a predominantly qualitative and lesser quantitative approach, respectively. Interviews and focus group discussions were used to collect data. The study population was made up of farmers, agricultural extension officers and the Climate Change Adaptation in Africa project manager. Quantitative data was analysed using descriptive statistics and the SPSS, while qualitative data was analysed using content analysis. Reliability and validity were ensured by methodological triangulation, pretesting the interview guides and careful transcription of the data. The key findings showed that farmers’ training is crucial in mitigating the impacts of climate change and variability for agricultural development. The study found farmers had a problem with accessing and using climate information. Farmers perceived scientific information on weather as unreliable and untimely and were turning to indigenous knowledge (IK) to predict weather patterns. Repackaging of timely and accurate information on climate change and variability, education and training for farmers and collaboration between researchers, meteorology experts, extension officers and farmers are recommended for implementation to mitigate the adverse effect of climate change and variability on farmers. A clear policy framework for the dissemination of information related to climate change and variability is needed. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

The effect of enacted capabilities on adoption and utilisation of innovative information systems : a study of small- and medium-sized enterprises.

Salleh, Noor Akma Mohd Unknown Date (has links)
This thesis is motivated by the need to establish a model covering innovative information systems (IS) adoption behaviours within small and medium-sized enterprises (SMEs). Studies on adoption behaviour related to innovative IS are devoting increasing attention to SMEs. Most prior studies, however, have still relied on models developed from studies of large firms. The applicability to SMEs of findings and models developed from large firm studies is not without question as SMEs are not miniature versions of large firms. SMEs face different challenges and opportunities from large firms. This thesis empirically examined issues on the adoption behaviours of innovative IS by SMEs. In line with this objective, two research questions were established. First, what are the critical determinants that allow SMEs to overcome inhibiting factors and adopt an innovative IS? Second, what are the critical determinants that ultimately activate and stimulate them to become enabled and actively utilise an innovative IS? The conceptualisation of enacted capabilities, adapted from the resource-based view of the firm is introduced. This thesis postulates that appropriate enacted capabilities facilitate SMEs to become enabled and actively utilise an innovative IS. These enacted capabilities include the level of IT skills and knowledge of the enterprises’ members, trust in technology, trust in trading partners, external experts’ support, and organisational culture Models incorporating aspects of the theory underlying the technology acceptance model (Davis, 1989), the diffusion of innovation theory (Rogers, 1995), and the resource-based view of the firm (Barney, 1991) were developed to describe the causal linkages between the determinants that activate and stimulate innovative IS adoption behaviour (i.e., from adopting to enabling to utilising innovative IS). One model was developed for the adoption stage and a second for the enablement and utilisation stages. The adoption stage model contains three main hypotheses. The first two hypotheses propose that enacted capabilities have a positive direct effect on both perceived net benefits and attitude towards adoption from a competitive advantage perspective. The third hypothesis proposes that perceived net benefits have a positive effect on attitude towards adoption form a competitive advantage perspective. The enablement and utilisation stages model contains four main hypotheses. The first two hypotheses propose that enacted capabilities and attitude have positive effects on perceived net benefits. The last two hypotheses propose that perceived net benefits and attitude towards adoption from a competitive advantage perspective have positive effects on the extent of enablement and usage of innovative IS. The hypotheses are tested using data obtained via a survey and follow-up interview. Responses were received from 206 SMEs of varying industries and sizes from the survey. Out of these 206 SMEs, follow-up interviews were conducted with twenty-one SMEs. The interviews utilise a combination of both open and closed questions. The questions for the follow-up interviews were based on findings derived from the survey. The innovative IS examined was the Malaysian government’s electronic procurement system, known as ePerolehan. All government suppliers must register for the system and become enabled for use before they can start utilising the system. The results indicate that enacted capabilities possessed by SMEs affect perceived net benefits at all stages of adoption behaviours of SMEs (i.e., adoption, enablement and utilisation). More significantly, two aspects of enacted capabilities, top management IS skills and knowledge and trust in trading partners dominate the effect on perceived net benefits. Support from external experts dominates the effect on attitude at the adoption stage. Top management IS skills and knowledge and trust in technology have a negative effect on attitude at the time of adoption. Enacted capabilities also contribute to the extent of enablement and usage within SMEs. Furthermore, different categories of adopters differ in the set of enacted capabilities underlying their innovative IS adoption behaviour. Results also indicate that when SMEs perceived higher net benefits in adopting innovative IS, they have a positive attitude. The positive attitude generated at the time of adoption has a direct effect on the extent of enablement and usage. The influence of perceived net benefits differs at the different stages of adoption behaviour. At the utilisation stage, usage is affected by perceived net benefits, however, perceived net benefits do not affect the extent of enablement at the enablement stage. In conclusion, this thesis found that enacted capabilities display important roles as antecedents to perceived net benefits, and that perceived net benefits act as a mediator from enacted capabilities to attitude at the adoption stage. Enacted capabilities also display important roles as stimulators of the extent of enablement and usage. Thus, apart from requiring good ideas and financial resources, SMEs also require appropriate enacted capabilities when adopting, enabling and utilising innovative IS.

Moving from meat: vegetarianism, beliefs and information sources

Lea, Emma J. January 2001 (has links)
A random population survey (n=601) and a survey of vegetarians (n=106) were conducted to examine South Australians' beliefs about meat and vegetarianism. Meat beliefs, barriers and benefits of vegetarianism, meat consumption, personal values, use of and trust in sources of food/nutrition/health information and demographic variables were measured via a written questionnaire. There were differences in the responses of vegetarians, semi-vegetarians, and non-vegetarians. For example, vegetarians were more likely than non-vegetarians to use and trust unorthodox information sources and to hold universal values (e.g. 'equality'). The factors associated with meat consumption and four sets of health-related beliefs about meat and vegetarianism (Meat is Necessary, Vegetarianism Health Concerns and Appreciates Meat, Meat is Unhealthy, Health Benefits of Vegetarianism) were examined. Other (health and non-health) beliefs, barriers and benefits of vegetarianism were the most important factors overall to be associated with these beliefs and with meat consumption. Information sources were also associated (particularly orthodox, unorthodox, mass media, advertising, and social sources). Together, these results provided insight into how consumption of meat and plant foods might be influenced. Finally, the proportion of prospective vegetarians was gauged. Approximately 15% of non-vegetarians were found to hold similar beliefs about vegetarianism as vegetarians. Prospective vegetarians were distinct from vegetarians and the remaining omnivores. For example, they were less likely than the remaining omnivores to eat red meat as frequently or to be Anglo-Australian. The research suggested that a significant portion of the population is interested in vegetarian diets, but that certain barriers need to be overcome if this is to increase and lead to dietary change; in particular, the beliefs that vegetarian diets are nutritionally inadequate and that meat is essential for health. Tailored communications about how to prepare healthy, tasty vegetarian meals may also be useful. The results indicated the sources of food/nutrition/health information that may be most appropriate to disseminate such messages. Additionally, it was found that ethical (e.g. environmental, animal welfare) issues were linked to health and dietary behaviour. They may need to be more fully addressed by health professionals if the public is to obtain maximum benefit from plant-based diets, with minimum risk. / Thesis (Ph.D.)--Department of Public Health, 2001.
