The use of electronic information resources in the university of Fort Hare Library Services

Maya, Zukiswa January 2018 (has links)
The study seeks to explore the use of electronic information resource in the University of Fort Hare (UFH) Library. The objectives of the study are to determine factors that influence acquisitions of electronic information resources at UFH library, to find out the user’s responses to electronic information resources in the library and identify the challenges faced by UFH library regarding the usage of electronic information resources. The literature review was conducted through an acquisition of electronic information resources in academic libraries, collection development policies of academic libraries in South Africa and application of electronic information resources within South Africa and globally. The study is based on Diffusion of innovation (DOI) theory. The study adopted qualitative and quantitative approaches, and the non-probability sampling-Quota sampling was used for students and purposive sampling technique for librarians and academics. The data was collected with self-administered questionnaires and document analysis. The study found that academics were not fully involved in the acquisition of the library electronic information resources; therefore, there is a lack of communication about the acquisition of electronic resources. The study further reveals that there is usage of electronic information resources; however, there are library users who prefers to use search engines such as google, yahoo etc. It was also identified that there are two important barriers that hinder the use of electronic information resources, i.e. physical and personal barriers. The study recommends that University of Fort Hare library should consider including e resources in the collection development policy. It is also recommended that the library online training/tutorials must be installed on the library website to increase the usage of e-resources. In order to stay relevant and visible, librarians should embrace new opportunities and go beyond the comfort zone of traditional librarian principles.

Older people as equal partners in the creative design of digital devices

Sustar, Helena January 2011 (has links)
This thesis describes research which explores the importance and feasibility of involving older people as equal partners in the creative design of digital devices for an ageing population. In exploring this topic, I have carried out two preliminary studies, a pilot study and a major empirical study. Firstly, I invited three groups of people, including very old people, active older people and postgraduate students, to evaluate a mock-­‐up model of an interactive device intended for older people that was designed using a standard design process. The results of this study suggested that products without an adequate contribution from older people would not always meet their needs. Secondly, I carried out observations of very old people, active older people, and young designers to identify factors that influence the way in which both older people and young designers can be involved in the creative design process. These factors included experiences with technology, processes and approaches currently applied with older people and designers, factors that stimulate or inhibit creativity, and practical constraints such as health issues. The results of these observations fed into the design of a pilot study, where I tested the content of a creative design process and a procedure for analysing data for the main empirical study. The main study involved three creative workshops where the same creative methods were employed with different sets of people: young designers, mixed groups (with older people and designers) and older people only. The results show that older people are able to participate in a creative design process; however, certain practical constraints have to be taken into account. Also, older people perform better when they work together with designers. Finally, the mixed groups with older people, who have relevant life experiences, and designers, who are familiar with the newest technology, may be more suitable for designing appropriate products for the older population.

Regulating competence-based access to agent societies

Lekeas, George K. January 2011 (has links)
Advances in ubiquitous computing have resulted in changes to the way we access and use everyday applications, e.g. reading mail and booking tickets. At the same time, users interact with these applications in a variety of ways, each with different characteristics, e.g., different degrees of bandwidth, different payment schemes supported and so on. These are highly dynamic interactions, as some of the applications might become unavailable (either temporarily or permanently) or their behaviour may change. As the user has to deal with a large number of proactive and dynamic applications every day, he will need a personal assistant that possesses similar characteristics. The agent paradigm meets this requirement, since it exhibits the necessary features. As a result, the user will provide its personal agent assistant with a goal, e.g. I need a smartphone which costs less than three hundred pounds, and the agent will have to use a number of applications offering information on smartphones so that it finds the requested one. This, in turn, raises a number of issues regarding the organisation and the degrees of access to these services as well as the correctness of their descriptions. In this work, we propose the organisation of applications around the concept of artificial agent societies, to which access would be possible only by a positive evaluation of an agent's application. The agent will provide the Authority Agent with the role it is applying for and its competencies in the context of a protocol, i.e., the messages that it can utter/understand. The Authority Agent will then check to see if the applicant agent is a competent user of the protocols; if yes, entry is granted. Assuming that access is granted, the next issue is to decide on the protocol(s) that agent receives. As providing the full protocol will cause security and overload problems, we only need to provide the part required for the agent to play its role. We show how this can be done and how we can repair certain protocols so that they are indeed enactable once this role decomposition is performed.

Field level information collaboration during complex humanitarian emergencies and peace operations

Schwent, John T., Barge, Hezekiah, Jr. 06 1900 (has links)
Approved for public release; distribution is unlimited / Multinational humanitarian and military efforts such as those seen in Somalia, Kosovo and Afghanistan are known as Complex Humanitarian Emergencies. These types of emergencies are complex and difficult to operate in because they contain political, military and humanitarian considerations. The various actors responding to a CHE can be divided into two distinct groups - military and civilian. Each of these groups needs the other to effectively respond to the crisis. Thus communication, collaboration and coordination are critical. Technology can play a significant role to enable information sharing between the various participants during CHEs. This thesis documents the continued development of a collaborative, Information Technology-based, operation support system designed to facilitate information sharing at the field/tactical level during CHE and Peace Operations. The operational support system was designed in the context of a Tactical Humanitarian Relief Habitat and will undergo a technical evaluation in a simulated CHE/Peace Operations environment. The end state of our research will result in recommendations for continued development of a habitat designed for utilization in the Civil Military Operations enter of a CHE or Peace Operation. / Major, United States Marine Corps / Captain, United States Marine Corps

The use of computerised personnel information systems by human resource specialists in the public sector

Fisk, Barbara Susan January 1993 (has links)
This thesis examines the development of human resource management in three UK public sectors local government, the health service and higher education. The focus of the study is the problem of the lack of use of computerised personnel information systems by personnel specialists to develop the human resource management function. The literature of strategic management, human resource management and the fit between them are reviewed together with the history and the development of personnel systems in the UK. Senior personnel practitioners and their organisations in the three sectors were evaluated with respect to the stage of development of organisational planning and the contribution made by personnel practitioners using questionnaires, and in-depth interviews. The backgrounds and management styles of the practitioners were examined in order to evaluate their perceptions of: human resource management, computer systems and organisational planning. The degree to which practitioners made use of their computerised information systems for administrative and strategic purposes and the problems they perceived were evaluated in order to judge their degree of evolution from 'traditional personnel practice' to 'human resource management'. The research findings indicated that, although there were are number of significant differences between the three sectors studied, these had little effect when considering the broad issues embedded in the six hypotheses. The evaluation of these hypotheses indicated that the practitioners were making substantial use of their systems for administrative but not for strategic purposes. The number of perceived forces discouraging use and development of computerised personnel information systems was found to outnumber the perceived encouraging forces and were aggregated into a forcefield diagram. Furthermore it was shown that most practitioners had not yet evolved into proactive human resource managers. Suggestions for 'best practice' with respect to choice, use and development of CPIS are provided.

Studying online support communities : investigating network patterns and characteristics of social support

Pfeil, Ulrike January 2011 (has links)
People’s activities on the internet have expanded from mainly retrieving information to communicating with each other in virtual settings. Thus, research investigating social interactions in online communities is becoming more and more important. However, the multi-faceted approaches of existing studies for the analysis of online communities make it difficult to combine the findings into a comprehensive understanding. This shows the need for holistic investigations of online communities. This thesis provides such a holistic approach by investigating a combination of different aspects of a selected online support community for older people. MOSuC (Model of Online Support Communities), a model describing the key aspects of online support communities was developed based on existing theories of computer-mediated communication (CMC) as well as theoretical perspectives on social support. Five studies were conducted, each addressing one of the different aspects of the case study community: (i) the message content, (ii) the conversations structure, (iii) the social network of related community members, (iv) the roles that online community members take on, and (vi) the taget population’s needs concerning the exchange of social support in online communities. The findings of these individual studies were then combined in context of MOSuC in order to provide a holistic description of the community. As a result, this thesis provides detailed insight into the characteristics of the case study community as well as the interplay and dependencies between different aspects of the community. Based on the integration of multiple studies, the thesis sheds light on two main issues: the characteristics of the individual aspects of the community as well as how these aspects are related to and affect each other. In addition to the findings of the studies, the thesis also contributes MOSuC, which serves both as a theoretical framework of the aspects of online support communities, as well as a practical tool for integrating the individual studies. In addition, the application, modification and integration of multiple methods in this thesis provide a novel methodological way for an integrative analysis of online support communities.

A data warehouse structure design methodology to support the efficient and effective analysis of online resource usage data

Ferreira, Cornél January 2012 (has links)
The use of electronic services results in the generation of vast amounts of Online Resource Usage (ORU) data. ORU data typically consists of user login, printing and executed process information. The structure of this type of data restricts the ability of decision makers to effectively and efficiently analyse ORU data. A data warehouse (DW) structure is required which satisfies an organisation’s information requirements. In order to design a DW structure a methodology is needed to provide a design template according to acknowledged practices. The aim of this research was to primarily propose a methodology specifically for the design of a DW structure to support the efficient and effective analysis of ORU data. A variety of relevant DW structure design methodologies were investigated and a number of limitations were identified. These methodologies do not provide methodological support for metadata documentation, physical design and implementation. The most comprehensive methodology identified in the investigation was modified and the Adapted Triple-Driven DW Structure Design Methodology (ATDM) was proposed. The ATDM was successfully applied to the information and communication technology services (ICTS) department of the Nelson Mandela Metropolitan University as the case study for this research. The proposed ATDM consists of different phases which include a requirements analysis phase that was adapted from the identified comprehensive methodology. A physical design and an implementation phase were included in the ATDM. The ATDM was successfully applied to the ICTS case study as a proof of concept. The application of the ATDM to ICTS resulted in the generation and documentation of semantic and technical metadata which describes the DW structure derived from the application of the ATDM at a logical and physical level respectively. The implementation phase was applied using the Microsoft SQL Server integrated tool to obtain an implemented DW structure for ICTS that is described by technical metadata at an implementation level. This research has shown that the ATDM can be successfully applied to obtain an effective and efficient DW structure for analysing ORU data. The ATDM provides guidelines to develop a DW structure for ORU data and future research includes the generalisation of the ATDM to accommodate various domains and different data types.

Retrieving information from compressed XML documents according to vague queries

AlHamadani, Baydaa January 2011 (has links)
XML has become the standard way for representing and transforming data over the World Wide Web. The problem with XML documents is that they have a very high ratio of redundancy, which makes these documents demanding large storage capacity and high network band-width for transmission. Because of their extensive use, XML documents could be retrieved according to vague queries by naive users with poor background in writing XPath query. The aim of this thesis is to present the design of a system named “XML Compressing and Vague Querying (XCVQ)” which has the ability of compressing the XML document and retrieving the required information from the compressed version with less decompression required according to vague queries. XCVQ first compressed the XML document by separating its data into containers and then compress these containers using the GZip compressor. The compressed file could be retrieved if a vague query is submitted without the need to decompress the whole file. For the purpose of processing the vague queries, XCVQ decomposes the query according to the relevant documents and then a second decomposition stage is made according to the relevant containers. Only the required information is decompressed and submitted to the user. To the best of our knowledge, XCVQ is the first XML compressor that has the ability to process vague queries. The average compression ratio of the designed compressor is around 78% which may be considered competitive compared to other queriable XML compressors. Based on several experiments, the query processor part had the ability to answer different kinds of vague queries ranging from simple exact match queries to complex ones that require retrieving information from several compressed XML documents.
