Access to and impact of information technologies at Balme Library, University of Ghana

Afrane, Daniel Akwasi 12 1900 (has links)
Libraries, particularly academic libraries implement technologies to enhance their services to promote teaching, learning and research. In this thesis the impact of information technologies (library technologies) on delivery of services at the Balme Library of the University of Ghana was evaluated. The researcher adopted the multi-methods approach to the research by using a semi-structured questionnaire to collect data from users (students) of the library and para-professional staff of the Balme Library of the University of Ghana who formed one group of the study. The interview was used to collect data form professional staff of the library who on the other hand formed the second group of the study. Responses of the data collected from the two groups formed the components of the study and data collected quantitatively were analysed using univariate analysis method and interpreted by the descriptive and inferential statistics method. The qualitative data, on the other hand, was analysed using the narrative analysis approach. The findings of the study reveal that a variety of IT facilities such as computers, internet, photocopiers, scanners, braille embossers, magnifiers for reading, reference management software, video conference facility, electronic theses, electronic databases, automated library system, electronic past questions and the library website are available at the library and are very accessible to all users (students) and staff of the library. Students and staff of the library have good IT skills to utilise those resources. The findings also reveal that the IT infrastructure had positive impacts on the delivery of library services ensuring that users received the appropriate services they needed at the right times and places The study found challenges of slow internet connectivity, unstable power supply, lack of IT skills, inadequate IT infrastructure among others and these hinder the maximum utilisation of IT in and out of the library and recommends periodic training of staff and users, proper maintenance of facilities, increase of internet bandwidth and better marketing of library services / Information Science / M.

An integrated sensor system for early fall detection

Bandi, Ajay Kumar 05 1900 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Physical activity monitoring using wearable sensors give valuable information about patient's neuro activities. Fall among ages of 60 and older in US is a leading cause for injury-related health issues and present serious concern in the public health care sector. If the emergency treatments are not on time, these injuries may result in disability, paralysis, or even death. In this work, we present an approach that early detect fall occurrences. Low power capacitive accelerometers incorporated with microcontroller processing units were utilized to early detect accurate information about fall events. Decision tree algorithms were implemented to set thresholds for data acquired from accelerometers. Data is then verified against their thresholds and the data acquisition decision unit makes the decision to save patients from fall occurrences. Daily activities are logged on an onboard memory chip with Bluetooth option to transfer the data wirelessly to mobile devices. In this work, a system prototype based on neurosignal activities was built and tested against seven different daily human activities for the sake of differentiating between fall and non-fall detection. The developed system features low power, high speed, and high reliability. Eventually, this study will lead to wearable fall detection system that serves important need within the health care sector. In this work Inter-Integrated Circuit (I2C) protocol is used to communicate between the accelerometers and the embedded control system. The data transfer from the Microcontroller unit to the mobile device or laptop is done using Bluetooth technology.

Emotional communication in instant messaging

Pirzadeh, Afarin 29 October 2015 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Emotional communication is fundamental to everyday interaction. How well emotions are communicated is crucial to interpersonal relationships and individual well-being. Emotional communication in instant messaging (IM), however, can be challenging because of the absence of visual and aural nonverbal behaviors. Despite the growing number of technologically-focused solutions for supporting emotional communication in IM, limited design research has been done to study the actual users’ behaviors in communicating their emotion in IM and strategies they use to adapt emotional communication in this medium, with the purpose of establishing design solutions to support users' emotional communication. Connecting several bodies of HCI, design, and communication literature in the context of IM, this dissertation critically examines how users communicate emotion in IM and accordingly establishes user-centered multi-touch gesture based design solutions to support emotional communication in this medium. Understanding how users communicate their emotion in IM, the design issues, and corresponding design solutions help researchers and designers to support the user's emotional needs, resulting in the improvement of emotional communication strategies in IM.

A model for the adoption and acceptance of mobile farming platforms (MFPs) by smallholder farmers in Zimbabwe

Masimba, Fine 01 1900 (has links)
D. Tech. (Department of Information and Communication Technology, Faculty of Applied and Computer Sciences), Vaal University of Technology. / The agriculture sector is the lifeblood of the economies of the world's least developed countries (LDCs). In Zimbabwe, this sector is considered to be the backbone of Zimbabwe's economy, and as a result, it is the sector that supports the economic growth of the country, food security, and poverty eradication efforts. Furthermore, the use of mobile technology has continued to rise in Zimbabwe, and farmers now can obtain agricultural information through the use of mobile technology. Mobile phones are increasingly being integrated into current agricultural trade businesses, owing to the critical role they serve in facilitating information transmission between farmers and buyers. The potential of mobile phones in agriculture spawned mAgriculture, which is the use of mobile phones to provide agricultural information and services. Variousitechnology companies in iZimbabwe have come up with various mobile farming platforms as innovation, with the aim of improving overall performance among smallholder farmers. In order to find the usefullness of these mobile farming platforms, it imperative to measure the adoption and acceptance of this technology in the farming environment. The study sought to investigate the adoption and acceptance of mobile farming platforms in Zimbabwe through a more comprehensive model based on UTAUT 2 that encapsulates the key factors that influence user adoption and acceptance of mobile farming platforms. The main aim of the study was to inform technology start-up companies and other mobile application developers in the development of mobile farming platforms or applications that can be fully adopted and accepted by users, taking into cognisance all salient factors affecting their adoption and acceptance. The model has been used to investigate smallholder farmers in a developing country such as Zimbabwe. The model explores the effect of attitude as one of the key determinants that affect the behavioral intention to use mobile farming platforms. In addition, the model looked at the moderating effect of Hofstede's five cultural dimensions on the key determinants that influence behavioral intention as well as actual use of mobile farming platforms at individual level. A total of 411 questionnaires were received from smallholder farmers in Zimbabwe's three major provinces who were using mobile farming platforms. Structural Equation Modelling was utilized to test the hypothesized conceptual model. Reliability and validity checks were done to the model instrument. As hypothesized, the findings of this study revealed that performance expectancy (PE), effort expectancy (EE) and facilitating conditions (FC) are significant determinants of the newly added variable Attitude (AT). Attitude (AT), together with social influence (SI), facilitating conditions (FC), hedonic motivation (HM), price value (PV), and habit (HB) were found to be significant determinants of behavioral intention and usage of mobile farming platforms for smallholder farmers. The results also showed that cultural dimensions have a moderating effect on user acceptance of mobile farming platforms. According to the findings, attitude and culture are significant factors to consider when analyzing farmers' behavioral intentions and use of mobile farming platforms. The findings of the study contribute to the literature by validating and supporting the applicability of the extended UTAUT 2 for the adoption and acceptance of mobile farming platforms by smallholder farmers in developing countries. The theoretical contribution of the study was through the extension of UTAUT 2 where attitude was added as one of the new key determinants of behavioral intention and cultural dimensions were added as mediators. The other contribution is to the Zimbabwean farming community where the study was conducted.

Technology challenges faced by rural women in the Eastern Cape province of South Africa: a case study in the Chris Hani Municipality

Chisango, Grasia 06 1900 (has links)
The study sought to explore technology challenges faced by some rural women in Intsika-Yethu and Emalahleni local municipalities, under the Chris Hani District Municipality, in the Eastern Cape Province of South Africa. Available literature reveals that some rural women in South Africa and other developing parts of the world face technology challenges. The study is qualitative and focuses on two municipalities. Thirty-two women participated in the study. Data were collected through in-depth interviews and focus group interviews. Data were presented, analysed and discussed according to the themes derived from the sub-research questions. It emerged from the study that while most women in both municipalities were aware of ICT, they are however facing ICT access challenges in most areas of the municipalities. The findings do not depict the South African government national ICT policy goals which realises the importance of technology in the integration of services for the development of rural areas. Designing intervention programs for secondary school girls and some rural women, as well as monitoring and evaluating ICT programs in rural areas are recommended. / Communication Science / MA ( Communication)

Communication across cultures and its implications: the case of black indigenous Zambians and white western migrants living in Zambia

Silungwe, Wilson January 2014 (has links)
The overarching aim of this study was to explore the similarities and differences in communication and other cultural practices in encounters between black indigenous Zambians and white Western migrants living in Zambia and the implications of these similarities and differences. The research adopted a qualitative research design, and focus group discussions were used as a data collection tool, using a video recorder to capture the discussions. The focus group comprised of 6 black indigenous Zambians and 6 white Westerners. The collected data was then transcribed from the video records and analysed using thematic analysis. The conclusion to this study is that the culture of black indigenous Zambians and that of white Westerners have both similarities and differences as far as communication practices and other practices are concerned. These similarities and differences influence communication encounters between the people of the two cultures either positively or negatively rendering communication either effective or non-effective. / Communication / MA (Communication)

Access and usage of information and communications technology thorough public access centres in Letlhakeng rural village in Botswana / Access and usage of Information and Communications Technology through public access centres in Letlhakeng rural village in Botswana

Lebele, Ayanda Agnes 02 1900 (has links)
This dissertation acknowledges that despite the global initiatives towards an inclusive information society, there are still some disparities in how communities access and use the information and communication technologies (ICTs) that are available. These disparities, or digital divide, have been interpreted and addressed from different interrelated theoretical view points. The provision of ICTs through public access centres has been widely applauded as one of the strategies to enable especially disadvantaged communities to participate in today‟s information led economy. Botswana has adopted the just noted approach. The country has also developed policies and supportive infrastructure to enable especially the rural communities to be part of the global information society. It is however regrettable that access and usage of ICT‟s is still notably low in rural communities. The concern over this worrisome situation motivated this study to explore the factors that enabled or inhibited access and use of ICTs that were available to the Letlhakeng community through public access centres. This descriptive case study was conducted in four sequential stages: designing, conducting the research, data analysis and development of conclusions. The study was characterized by a continued comparative analysis of data which was collected through interviews; observation and review of related documents from the service providers; the users and non users of the services. The Letlhakeng community had access to ICTs through individually owned stand alone centres and from government supported centres. These centres were used by both residents of Letlhakeng and people from nearby villages. The factors that promoted or inhibited access and use of the available ICTs differed within and between these communities. Despite the observed digital divide, the Letlhakeng community used the ICT public centres to access social services. There is a need to develop strategies to increase access to more technologies in the village and to equip the community / Information Science / D. Litt. et Phil. (Information Science)

Electronic word-of-mouth and country-of-origin effects: a cross-cultural analysis of discussion boards / Cross-cultural analysis of discussion boards

Fong, John January 2008 (has links)
Thesis by publication. / Thesis (PhD) -- Macquarie University, Macquarie Graduate School of Management, 2008. / Bibliography: leaves 124-133. / Introduction - Literature review -- Online word-of-mouth: a comparison of American and Chinese discussion boards -- Electronic word-of-mouth: a comparison of stated and revealed behaviour on electronic discussion boards -- A cross-cultural comparison of electronic word-of-mouth and country-of-origin effects -- Conclusion. / The growth of electronic discussion boards has enabled consumers from different cultures to communicate with people of similar interests. Through this online channel, marketing concepts such as word-of-mouth (WOM) and country-of-origin (CoO) effects have the potential to become more important because of the potentially large number of participants involved. The US and China, being the largest and second-largest online population in the world respectively, are ideal countries to investigate the frequency and extent of these marketing concepts. --The thesis consists of three separate but inter-related papers which have been published in journals or have been accepted for publication. Each paper builds on the one before and analyses different aspects of online consumer behaviour such as information-giving, information-seeking and the CoO statements made by participants of discussion boards. By examining and comparing the frequency and content of discussion postings on discussion boards within US and China based websites, the thesis makes a comparison of the information-giving and information-seeking behaviour of the discussants and also looks at the extent and the content of CoO statements made. Online observation of discussion postings from six different discussion boards (three each from the US and China) was conducted over two 90-day period in 2004 and 2005 and a total of 5,993 discussion postings were downloaded for analysis. In addition, an online survey of 214 participants was conducted to compare the stated and actual (or "revealed") behaviour of discussants on the US and China based discussion boards. -- Overall, the findings indicate consistent differences over a 12-month period in the bahaviour of the US and Chinese discussants. The US discussants were found to provide more information than their Chinese counterparts while the Chinese discussants exhibited more information-seeking bahaviour on the discussion boards. The findings also indicate that the Chinese discussants demonstrated more negative CoO statements and these statements were observed to be related to Japan and/or brands that originated from Japan. The findings suggest that such negative CoO statements can increase rapidly online and it appears that the negative sentiments by the Chinese were apparently unrelated to product quality; instead they appear to have been predominantly associated with war related animosity. -- These findings have important implications for marketers selling to the Chinese as discussion boards appear to be more important as a source of information for the Chinese than the Americans. Also, given that the Chinese discussants demonstrated a high level of negative CoO statements relating to products from Japan, marketers selling Japanese products to the Chinese must understand the underlying issues related to these negativeCoO statements and take steps to prevent non-purchase of Japanese products. / Mode of access: World Wide Web. / vii, 133 leaves ill
