Thesis submitted in fulfilment of the requirements and the award of the Degree of Doctor of Philosophy in the Department of Library and Information Science at the University of Zululand, South Africa, 2013. / The purpose of this study was to investigate the information needs and seeking behaviour of orphans and vulnerable children (OVC) and caregivers, and to examine the role of service providers in disseminating information to OVC and caregivers in Namibia. Although several studies focusing on different aspects of the OVC situation have been done, the researcher could not identify any study that focused on the information needs and seeking behaviour of OVC and their caregivers in Namibia and how the two groups satisfy their information needs at present. In order to obtain data from the respondents, the study adopted qualitative and quantitative research methods for data collection. A questionnaire was mailed to the sampled service providers, while interviews were conducted with OVC and caregivers. Focus group discussions were also held with caregivers and key informants in order to explore the general attitudes, feelings, beliefs, experiences and reactions of the research population with respect to information needs and seeking behaviours. The study took place in the rural community of Ohangwena and the urban setting of Khomas. A total of 566 OVC, 70 caregivers, and 18 services providers from both regions took part in the study. A total of eleven focus group discussions took place; eight focus group discussions were held in Ohangwena, while three were in the Khomas region. Both rural and urban OVC indicated that they needed information in order to access financial vii assistance/grants, child care/support, feeding schemes, and health services. The most important information required, according to the OVC from Ohangwena, was information on school development fund exemption, financial assistance or grants, health services, child care/support and training opportunities. The OVC from Khomas had similar priorities with the exception of training opportunities, which was replaced with counselling. Both rural and urban OVC consulted relatives, teachers, and friends to satisfy their information needs, indicating that people were their most important source of information. The findings from focus group discussions (FGDs) with caregivers and key informants indicated that there are disparities between rural and urban areas in terms of information access and use based on literacy and education. For example, the rural dwellers cited their need for information on educational support, psychological and counselling services, child care/support, and job opportunities. In the urban setting of Khomas, educational support and the establishment of small businesses featured as prominent needs. The FGDs revealed that the radio, traditional leaders, regional councillors, friends and relatives were the most important sources and channels of information in Ohangwena, while in Khomas, friends and relatives, community leaders, and regional councillors were the most popular channels. Social workers and the television were also popular channels in Khomas. The findings of the study indicate that service providers provide a range of services to OVC and caregivers in both rural and urban areas. In the rural areas, the majority of the supporting organisations had health-related programmes focusing on feeding schemes and nutrition, and HIV/AIDS awareness. In urban areas, service providers provided psychosocial support, counselling, and resilience services. The findings reveal that the majority of the service providers used community meetings and public forums to communicate their own information and to create awareness of their services in both regions. The channels that were most frequently used in Ohangwena were community meetings and open forums, while the use of volunteers featured prominently in Khomas. The OVC and caregivers encountered various problems in accessing information, including: long distance to access information and services; language barrier for printed materials; shortage of service providers in rural areas; lack of coordination of service providers; and viii bureaucratic red tape from government departments. Major recommendations stemming from the study include: the need for service providers to provide clear information on how to access the different services that target OVC and caregivers; service providers should collaborate and use mass media channels to disseminate information; the need for a “one stop shop” where all information related to OVC services would be made available; and the need to provide information in local languages. The study concluded that information provision is a crucial resource for OVC and caregivers because it helps them identify and take advantage of available services. Conversely, lack of information leads to the lower utilization of available services and increased poverty and disempowerment. Several recommendations are made on how to improve the flow of information to OVC and caregivers to help them easily locate and use facilities and services that have been set up for them either by the government, or by non-governmental organisations and other service providers. The study also proposes a model to improve the provision of information to OVC and caregivers in the two regions. / University of Zululand

Master of Science / Department of Horticulture, Forestry, and Recreational Resources / Rhonda Janke / With the increasing popularity of urban farming, more people are seeking resources to start their own farming/growing production in urban environments. Traditionally, county Extension educators are a key resource for beginning farmers and growers. However, urban Extension offices are often overlooked as resources in the urban farming planning process. The objectives of this study are 1) identify information urban farmers currently have, information they need, and their preferred delivery methods 2) look at the resources and information that are offered by local Extension educators in the KC metro area and 3) analyze how these two groups are communicating and what could improve to meet farmers‟ needs. This project evaluates current interaction between urban farmers and Extension educators in the Kansas City area through a two-pronged approach: a written mail-out questionnaire for urban farmers and growers in the Kansas City metropolitan area and through in-person one-on-one interviews with Extension educators that emphasize topic areas related to urban agriculture in the KC area. One hundred and nineteen farmers/growers were surveyed, and a 54.6% response rate was achieved. The majority of farmers had small, diversified farms and were relatively new to farming. Respondents were primarily older, white men that had higher education. Independently-driven sources (such as self-research, other farmers, and friends/family) were most commonly used sources among farmers. Overall, respondents ranked Extension highly in terms of information quantity, quality and as their "go to" source. Extension educators from Kansas State University, University of Missouri, and Lincoln University were interviewed one-on-one using scripted interview questions to determine topics and medias of information that are currently being offered. Production and processing information is offered the most by educators followed by distribution, equipment, and marketing information. Financial information was the least offered information topic. Extension educators use a wide variety of methods to distribute information. Most Extension educators are aware of benefits and barriers relating to urban agriculture in the KC metro area. Extension educators are addressing urban agriculture in varying degrees and the level of involvement corresponds to the Extension institution.

M.A. (Communication) / The study firstly proposed that marketing communication be approached within a social-psychological framework, where market related information is subject to both internal (cognitive) and external or social influences, specifically reference groups. The concept of information seeking within this framework implies that the consumer is actively involved in the interchange of market-related information, and that he actively seeks information relevant to his goals in the purchase situation. A broad spectrum of literature on information seeking was subsequently reviewed, which was then systemized according to the nature and sources of information seeking. It was established that normative social influence (which implies that the self concept determines information seeking) is found to operate only for informal personal sources and formal non-personal sources. Further, it was stated that where social influence is normative, it will impact only on consumer information seeking for social products. Based on this model, a number of propositions regarding the nature and sources of consumer information seeking for social products were formulated. These propositions formed the basis of the empirical part of the study. Items drawing on the propositions were incorporated into a Likert-type questionnaire which was handed to a stratified random sample of student consumers.

M.Inf. / For centuries man has relied on agriculture to sustain human life. Farmers, as usual, were concerned with growing crops, vegetables and breeding domestic animals for transport, meat and milk supply. Success in farming, especially stock farming was a sign of wealth. Land area for cultivation of crops and pasture for livestock was ample. So, if land gets depleted and cannot meet the needs of all adequately, farmers moved to other parts of the land where soils were still fertile. So, agriculture and stock farming relied heavily on nomadic farmers to find fresh fertile soils. Specialized agricultural information which is prevalent today was not necessary. However, as the world population increased, land areas diminished and man’s migration stopped. Soils depletion of minerals had to be re-used and technology was developed to aid in improving the quality of the soils. Fertilizers, manure and irrigation were introduced as did pesticides and herbicides which assisted in improving the quality and quantity of agricultural output. Information is a powerful tool in addressing these agricultural needs and if it is used appropriately it could change a nation’s economy. The purpose of the research was to investigate agricultural information needs of agriculturists and farmers in Lesotho and resources that are available to satisfy these needs. Therefore, it will be argued that relevant and timely information has to be organized according to language and format understood by different categories of agriculturists and farmers. Agricultural information that might be useful to improve productivity should be appropriately disseminated to users who may benefit from the information. Specifically, the research project investigated different categories of agriculturists and farmers and their type of agricultural information needs. Resources that are available in Lesotho and in organizations were also investigated in order to identify those that could be utilized to meet agriculturists’ and farmers’ needs. In order to arrive at this, the researcher did a literature study on the status of agricultural information in the developed countries (DC), the less developed countries (LDC) and Southern African Development Community (SADC). The project also looked at both the positive and negative factors that affect agricultural development in order to select which methods and resources could be adapted to address the needs of local agriculturists and farmers. The researcher used the interview method to collect data on agricultural information needs of agriculturists and farmers, as well as resources that are available to them in Lesotho. The purpose of the structured interview was to gather information related to the use of information sources, sources of agricultural information, document and information delivery and IT connectivity. The findings showed that farmers interviewed were spread evenly in agricultural farming of maize, sorghum, beans and vegetables; and stock farming of cattle, cows, piggery and poultry. iii Agriculturists indicated that the purpose for which agricultural information was needed included marketing of agricultural produce, research information and information for selfimprovement. Farmers on the other hand indicated that they needed agricultural information for advancement of primary production, community education, self-improvement and sustainable agriculture. Other major findings included concern for which pest control and sustainable agriculture. Current awareness services were also rated highly and publications were the method of dissemination that was preferred. Agricultural information that is cost-effective and appropriate was considered for purchase. In terms of acquisition and accession of information, results showed that most users preferred surface mail, as it is reliable and cheap, even though it is sometimes slow. Through it, bulky packages like books and journals could be sent.

M.Sc. (Nursing), Faculty of Health Sciences, University of the Witwatersrand, 2011 / In this present study, the instrument cardiac patients learning needs inventory (CPLNI) was assessed for validity and reliability by four cardiology doctors, two critical care nurses, and one patient with a history of myocardial infarction (stage one of the study). The instrument was not modified as a result of non modified CPLNI used in the pilot study which consisted of thirty seven items of information grouped into eight clusters (constructs). The aim of the study was to describe and compare intensive care nurses and patients perceptions of information needs of acute myocardial infarction patients at a public sector tertiary hospital in Johannesburg. The study has made recommendations for clinical practice and education of intensive care nurses. A quantitative, non experimental, descriptive, prospective two-part design using questionnaires was utilized in this study to find out what information out of that commonly given following myocardial infarction, patients and critical care nurses rated as being most and least important (stage two). These results were then compared with the results obtained from patients and nurses who were given the same instrument to complete. Seventy six subjects were recruited. Results indicated that some similarities existed between the patients and the nurses in terms of what they perceived as the most and least important clusters/constructs of information. The item one (what to do if I get chest pain)was ranked first with a frequency of seventy five(98,68%). The scores for some informational clusters included on the instrument were significantly different between the patient and the nurses groups (p<0.05). The constructs miscellaneous (p=0.0054), physical activity (p=0.0022) and symptom management (p=0.0284) were statistically significant. These findings and others are discussed, and recommendations are made for improving the information given on post myocardial infarction,

Background: No spine-specific educational tool has been developed using input from all relevant stakeholders, including patients. Purpose: The objective of this study was to determine the information needs of lumbar microdiscectomy patients. Methods: Qualitative methods with thematic analysis was used. Focus groups were conducted with: 1) preoperative microdiscectomy patients; 2) postoperative microdiscectomy patients; 3) spine surgeons; 4) spine fellows; 5) orthopaedic surgery residents; 6) anesthesiologists; 7) surgeons’ administrative assistants; and, 8) preoperative assessment team. Results: Major information needs were related to: anesthesia, surgical procedure details and postoperative course. Patients desire information on postoperative course much more than surgeons perceive. Desired attributes of information tools as well as patient factors that influence the extent of information shared by surgeons were determined. Information resources should be given to patients as soon as they are deemed surgical candidates. Conclusions: Microdiscectomy patients desire more information than currently provided to them – in particular postoperative-related information.

Information search and acquisition is one of the important tasks in industrial procurement. The main issues of the present study are whether the needs of information and their patterns of importance would be affected by the following variables: product type, position of the supply chain, factors of individual participant (position, current unit, experiences of departments), organization structural factors, innovational resources commitments. The empirical study contexts are six machinery related sub-industries, including: vehicle, casting, die and mold, fastener, hand-tool, and machinery industry. From the 345 valid survey samples, the current research tested several hypotheses, of which significant findings include: (1) Different positions at a supply chain would cause difference of information needs. (2) Factors of individual participant also bring about different buying information needs: the current unit and experiences in different departments would significantly affect importance of the finance-cost, technique, salesperson information. (3) Organizational factors, including authority, horizontal interaction, vertical division, would give rise to more positive effect on buying experiences, country-of-origin, salesperson information. On the other hand, solicit negative effect on finance-cost information. (4) The product type would significantly moderate the causal relation between organizational factors and buying experiences, country-of-origin, or salesperson information. (5) Finance-cost information is less important for the higher innovational commitment companies than the lower ones

Most information retrieval (IR) systems respond to users' representation of their information needs (queries) with a ranked list of relevant results, usually text documents. XML documents di er from traditional text documents by explicitly separating structure and content. XML-IR systems aim to exploit this separation by searching and retrieving relevant components of documents (called elements) rather than entire documents thereby, better ful lling users' information needs. Despite the potential bene t of XML-IR systems, most research in this area has not been centered on the needs of users. In particular, current XML-IR query formation interfaces, namely keywords-only and formal language, are not able to optimally address the needs of users. Keywords-only interfaces are too unsophisticated to fully capture the users' complex information needs that contain both content and structural requirements. In contrast, while formal languages are able to capture users' content and structural requirements they are too di cult to use, even for experts, and are too closely tied to the physical structure of the collection. This thesis presents a solution to these problems by presenting NLPX, a natural language interface for XML-IR systems. NLPX allows users to enter XML-IR queries in natural language and translates them into a formal language (NEXI) to be processed by existing XML retrieval systems. When evaluated by system testing, NLPX outperformed alternative translation approaches. When tested in a user-based experiment, NLPX performed comparably to a query-by-template interface, the baseline user-oriented interface for formulating structured queries. It is hoped that the outcomes of this thesis will help to refocus the eld of XML-IR around the user. This will lead to the development of more useful XML-IR systems, which will hopefully result in the more widespread use of XML-IR systems.
