The adoption of eHealth is very slow despite evidences showing its benefits. This research examines the individual, clinical, technical and organizational challenges for eHealth adoption from healthcare provider‟s perspectives. A cross-sectional study design with a quantitative paradigm was used. The study was conducted on 312 doctors and nurses randomly selected from ten hospitals in Addis Ababa, Ethiopia. Most respondents viewed eHealth positively with no significant differences in terms of profession or gender. Computer skill, workload, patient interaction, management support, cost and infrastructure were the main concerns. Privacy and security were not the main concerns. Knowledge of eHealth applications and utilization was low, even for evidence-based medicine and online databases. Specialists and males were better aware of eHealth applications. The study showed that eHealth acceptance was good. Increasing eHealth literacy was recommended as a cost effective means for improving access to updated information to improve the quality of healthcare. / Health Studies / M.A. (Public Health (Medical Informatics))

The role and impact of information and communications technologies (ICTs) towards enabling socio-economic development in small, medium and micro enterprises (SMMEs) has received attention from various scholars. South Africa as a lower middle-income developing country has a number of development priorities which include the urgent need to expand the economy and ultimately to eradicate poverty and unemployment. Based on evidence from more advanced economies, expanded access and usage of ICTs in SMMEs is considered an imperative to enable the acceleration of development goals. This study sets out to advance understanding of the role and impact of ICT usage by SMMEs on poverty reduction from a South African perspective. A systematic literature review methodology was applied to analyse previous theoretical and empirical studies conducted on the interplay between ICTs, SMMEs and poverty reduction. Empirical data was gathered from SMMEs through semi structured interviews and observations. A purposively selected case study was also carried out serving to enhance contextual insight into the role of ICTs in an SMME context. The thematic analysis method, Actor-Network Theory (ANT) and Sustainable Livelihood framework (SL) were applied as the data analysis methods. The combination of ANT and the SL framework for expanded analysis has not been applied before by similar studies that examine the interplay between ICT, SMMEs and poverty reduction. The process of triangulation was applied on the empirical findings in order to reduce bias and to construct a conceptual model. This study contributes to the body of knowledge by proposing a conceptual model that frames the role and impact of ICT usage by SMMEs towards improving their livelihoods and reducing poverty. Methodologically it offers an example of how method pluralism can be applied to gain a better understanding of the research phenomena. From a practical perspective, this study addresses real life challenges resulting in the suggestion of practical guidelines to ensure that the use of ICTs by SMMEs results in improvements in their financial and non-financial well-being. The findings of this study indicate that the relationship between ICT usage and poverty reduction is neither simple nor linear. Effective use of ICTs could result in SMMEs leveraging more benefits and thus improving their human capabilities as well as social and economic well-being resulting in poverty reduction. / Thesis (PhD) University of Pretoria, 2017. / Informatics / PhD / Unrestricted

The Role of Information and Communication in Organisations Diagnostic Tools of Information and Communication Processes The thesis has the objective to explore the interaction of the terms information and communication in organizational settings, and to identify their common characteristics and direct mutual influence.

The first part of the thesis provides an introduction into the theoretical terms information and communication as used in the historical context of their mother disciplines, identifies their similarities and differences, and, most importantly, highlights the long-term intense overlap of these terms at various levels. The second part goes on to introduce the basic forms of organizational structures affecting information transfer, i.e. direction, speed and accuracy of formal and informal information flows in organizational communication networks. The concept of information is brought into context with communication climate which has a direct influence on its form, quantity, quality and timeliness. When characterizing the most frequently used communication diagnosis tools falling into the category of...

Thesis submitted in fulfilment of the requirements for the award of the Degree of Doctor of Philosophy in the Department of Library and Information Science, in the Faculty of Arts at the University of Zululand, South Africa, 2004. / The purpose of this study was to investigate the ditTusion of Information and Communication Technologies (ICTs) in the communication of agricultural information among agricultural researchers and extension workers in Kenya. In particular. the study focused on the public agricultural sector and covered the Kenya Agricultural Research Institute (KARI) and the Ministry of Agriculture and Rural Development (MoARD). A survey research method. comprising a self-completed questionnaire and a structured interview schedule was utilized to gather data from the respondents. This was supplemented by observation and document review. The questionnaire was used to solicit information from agricultural researchers and extension workers. while the face to lilCe interview was used to obtain information from the key informants of the study. The agricultural researchers were drawn from the 21 KARI research centres distributed in all the eight provinces of Kenya and strategically spread to cater for different agroecological zones and socio-economic systems. The extension workers, on the other hand. were drawn from the Uasin Gishu and Baringo Districts, while the Key informants of the study were drawn from all the institutions surveyed. A total of 356 respondents compnsmg 159 agricultural researchers, 138 extension workers and 59 key informants participated in this study. The completed questionnaires were reviewed to determine their usability. Two questionnaires were discarded because they were incomplete. A total 01'295 questionnaires (159 agricultural researchers and 136 extension workers) and 59 recorded interviews were usable. This brought the lotal number ofrespondents to 354. It was observed that KARI and MoARD had adopted a wide variety of ICT tools and services in an effort to facilitate information sharing and exchange among agricultural researchers. extension workers, farmers and other actors involved in research and extension. These ranged from modern ICT based on digital information that included computers, the Internet and emaiL electronic sources. scanners. digital cameras among others. Traditional ICTs based largely on analogue information wa\'Cs included radio VI cassettes, tape recorders, television. video cameras, VCR. telephone. fax (analogue and digital) among others. lt was further established that the Agricultural Information Centre (AIC) had a modern radio studio equipped with professional sound recording equipment and editing suites amongst a variety of other video production facilities. The wide range of leT models adopted addressed the ditTerent kinds of intormation needs and commtmication problems encountered by agricultural researchers. extension workers and fanners. The agricultural researchers and extension workers had a critical need for information that was specific to the nature of their work. In addition. they needed information on agricultural policies and meteorology. The intormation needs of the two categories of respondents were met through the use of print and electronic sources. Agricultural researchers obtained useful infornlation from the Internet and CD-ROM databases with TEEAL database having the most useful information, while the Kenya Agricultural Research Database (KARD) provided useful information on local content. In contrast. the extension workers were disadvantaged as the majority lacked skills and physical access to ICTs. Their information needs were, therefore, met through the use of printed sources of information, and by attendance of meetings, workshops and seminars, Most of the respondents used ICTs to communicate among themselves and also with actors involved in research and extension. The Internet and email was used for consultation purposes, for communicating agricultural information, for research purposes and for collaborative projects with other colleagues. Radio, television and video were used in disseminating agricultural information to the farming community. Mobile phones were found to be a convenient means of communicating short messages. It was observed that use ofICTs had increased the respondents' work productivity and creativity. Information literacy programmes were taking place in the institutions surveyed although at different levels of intensity and continuity. Through the programme most of the respondents had improved their skills on the use of computers. Internet, emaiI and VII electronic sources. The programmes were better coordinated and managed at KARI than the Ministry of agriculture. Although ICTs had facilitated communication of agricultural information among actors involved in research and extension. it was yet to improve the linkage between agricultural researchers and extension workers. For ICTs to be levera~ed in the agricultural sector. it ~ ~ was observed tbat the agricultural researchers and extension workers should work more closely as tbeir activities are interrelated. Each group should play their roles in the multifaceted process of transmitting new knowledge of farm technology to farmers and getting their leedback. An attempt had been made to formulate institutional ICT policies to guide the dilTusion of ICTs at KARl and the Ministry of Agriculture. Implementation of these policies had been hampered by the lack of adequate funds. poor infrastructure and lack of commitment by some of the policy makers. The policies had also failed to address the over-reliance of donor funded projects, capacity building and skill development and to bring institutional changes. It was observed that the Kenya Government had formulated policies to guide liberalization. privatization and tariff reform. These policies had been implemented to a greater extent and had paved the way for the involvement of the private sector in the development of the various sectors of economy in the country. The government was also in the process of formUlating a comprehensive national ICT policy to provide guidelines in the ICT sector. Despite the efforts to expand and modernize lCTs in the agricultural sector, its gro\\1h had been hampered by a number of constraints and challenges. Among them includc inadequate funding; poor infrastructure: inadequate skill development; lack of comprehensive national and institutional ICT policies: lack of monitoring and evaluation system; inadequate provision of ICTs tools and services; poor maintenance, and overreliance of donor funded projects leading to a low level of sustainability. To address these problems requires the intervention and interaction of all the stakeholders in the agricultura~ and ICT sector and also involvement of the government. The study viii recommends the following: improvement of telecommunication inti'astructure and rural electritication: tormulation of comprehensive institutional and national lCT policies: alternative sources of tinance: employment of more IT personnel: comprehensive strategies on lCT skills development: reduction of taxes on lCT tools and services: development of responsive content: development of monitoring and evaluation mechanisms tor lCT projects: improvement of communication between agricultural researchers and extension workers: and adoption of FAO Virtual Extension. Research and Communication Network (VERCON) system to improve the linkage among and between actors involved in research and extension. It is concluded that despite the constraints and challenges encountered in the application and use of lCTs in the agricultural sector. a wide variety of ICTs had been adopted to tacilitate information sharing and exchange among agricultural researchers and extension workers. The application and use of these lCTs have a greater role to play in the context of the changing paradigms in agricultural research and extension. where linear information flows are being replaced by pluralistic information flows.

A thesis submitted in fulfilment of the requirements for the degree of Masters in Communication Science at the University of Zululand, South Africa, 2012. / Majority of developing societies are usually succumbing to numerous socio-economic challenges. Communities in Maseru, the capital of Lesotho, are not excluded from this trend. Online collaborations are consequently at the heart of addressing these challenges. This study examines the probability of encouraging and engaging online communication for social and economic development in Maseru. The promises of online communication for transforming society and advancing the new economy have rested on the arguments that online communication could expand and widen access to electronic commerce, enhance the quality of distance education, improve the general quality and standard of living , and eventually improve the economy of Maseru. Information Communication Technologies (ICTs) are very powerful tools for diffusing knowledge and information to society which is a fundamental aspect of the development process. The presence of new communication technologies has a greater influence on human lives than we ever thought. It is imperative that every community in Lesotho examines ways and means of adopting their information communication technology (ICT) infrastructure as soon as possible or face the possibility of social and economic stagnation and isolation. The Internet has ushered in innovative ways of socialising and conducting business. Although it has, through the process of globalization, created a wide space to engage in business and eradicate poverty, many societies are still isolated. There are many reasons for this which could range from voluntary isolation, inadequate infrastructure, ignorance or sheer laziness. The study was conducted within the paradigm of both qualitative and quantitative methods. Stratified and simple random sampling techniques were used and this allowed the researcher to divide the population of Maseru into various Strata. This research explored why Maseru is slow to adopt ICTs to enhance their economic and social development. Revelations from the study will benefit this community and will also assist in making recommendations for overcoming economic and social decline.

Logistics managers work to create practices that reduce technostress, which is associated with diminished productivity in supply chain management. The purpose of this multiple case study was to explore the mitigation strategies that logistics managers at distribution centers used to reduce technostress with their employees in the Los Angeles County, California area. The conceptual framework included in this study was the sociotechnical systems theory. Semistructured interviews were conducted with 6 logistics managers from large distribution centers who implemented mitigation strategies that demonstrably reduced technostress with their employees. Public documents and physical artifacts reviewed in this study included productivity assessment tools, information and communication technology system training materials, technostress mitigation instruments, and information from technological devices. Data were analyzed through a process of pattern matching, cross-case synthesis, and systematic text condensation. The findings included 6 themes: reliance on internal information technology experts; hiring temporary experts; maintaining communication and training; using time management skills and organizing priorities; identification and understanding of employee differences; and implementing well-being, fitness, and health programs. These findings could contribute to positive social change by providing logistics managers with strategies to reduce technostress, which could lead to improved employee well-being, better work conditions, and increased productivity for greater company profitability that could produce a more thriving and prosperous community.

The advance and ubiquitous use of Information and Communication Technology (ICT) have changed how humans learn and reform the education sector. Although related topics have been studied in other disciplines (e.g., behavioral science, economics, psychology, etc.), IS researchers have paid less attention to the impacts of information communication technology on education (IICTE). Recently, education in the post-pandemic world calls for further investigation on this topic since most of the traditional on-site teaching around the world have moved online. The proposed two studies aim to contribute to the IS and the economics research on the role of technology in education and the underlying mechanisms of how ICT affects learning through a series of field experiments and data mining methods. The first study examines in-class mobile device use effects on students’ learning performance via a field experiment. It explores students’ attention allocation at an individual level with live video feed data. We collaborated with a vocational school in China to examine the effect of using smartphones in the classroom on students’ academic performance. We randomly allocated students taking one lecture in Chinese verbal into three experimental conditions: (i) smartphone banned; (ii) smartphone allowed and used at will by students, and (iii) smartphone allowed, used at will by students and relied upon by teachers to assist instruction. We measure the performance gain of students by the change in the scores they obtained in identical tests taken at the beginning and the end of the lecture. We find that allowing students to use smartphones during the lecture at will reduced performance by 12% (6.3 points on a 100-point scale) compared to when students could not take the smartphones into the classroom. However, allowing smartphones into the classroom and asking teachers to actively use them to assist instruction increased their performance by 20% (10.6 points). These results are driven mainly by already strong students and students in IT-related majors. To unravel the underlying mechanisms that drive the observed effects, we use video feeds collected during our experiment, allowing us to code the time students spent learning versus being distracted, with or without their smartphones. We observed that students spent a similar amount of time learning versus being distracted across all three experimental conditions. Thus, the time students allocate to learning in each condition does not predict performance. Instead, what matters for their performance is the relative time they spent learning versus being distracted when using their smartphones. We show that the increase in performance when smartphones are used to assist instruction comes from students spending a larger percentage of the time learning during the lecture. Our findings contribute to the literature on technology-assisted learning and offer practical and policy implications that teachers and schools can follow to cautiously allow smartphones in the classroom to improve student success. The second study investigates the effects of different Internet access policies on student performance via a field experiment and examines the underlying mechanisms of its impact by mining students’ online and offline behaviors. While universities invest a considerable amount to keep up with the increasing demand for Internet connectivity on campus, sufficient doubt exists on the overall efficacy of information communication technologies (ICTs) in enhancing learning. Therefore, it is essential to understand how the Internet is used on campus and whether educational institutions can design their ICT policies to improve education. To answer this question, we seek to investigate the effects of different Internet policies on educational outcomes (i.e., grades, other evaluation results, etc.) by conducting a randomized field experiment at a national public university in China. Specifically, we randomly assigned students to five experimental conditions for a whole semester: low bandwidth and limited data, low bandwidth with unlimited data, high bandwidth with limited data, high bandwidth with unlimited data, and high-quality access (high bandwidth without data limit) yet limited data to entertainment. We then collect and compare the educational outcomes and each student’s online and offline behaviors across all five conditions. With our unique context and micro-level data, we investigate the overall effect of different policies as well as the dynamics of students’ online and offline learning behaviors (i.e., online learning time, online-offline behavior change, etc.) to understand the underlying mechanisms (i.e., online/offline learning patterns on performance). Our study is the first to investigate the effect of ICT policy design on educational outcomes using a randomized controlled trial (RCT). We also offer practical guidelines to policymakers and educational institutions on optimizing campus Internet access to help improve students’ learning with the proper use of ICT. Ultimately, studies in this dissertation attempt to explore how ICT could boost learning and thus extend the boundary of IS research to the education sector. Results demonstrated in the dissertation offer clear and straightforward evidence for educators, parents, and students to make their own ICT use policies. / Business Administration/Management Information Systems

This dissertation comprises three papers introducing strategies, models, and frameworks to guide pandemic response. The first paper uses a novel mathematical model to analyze the coordination between government and humanitarian non-governmental organizations (NGOs) in response to pandemics. This is a vital form of public-private partnership between governments as the primary source for the humanitarian supplies required during a crisis and aid organizations. This coordination involves the equitable distribution of personal protective equipment, including face masks and face shields among health workers, patients, and the public in hospitals. Considering social costs such as deprivation and equity costs in the model, in addition to the other important classic cost terms, enables managers to organize the best possible response when such outbreaks happen. The second paper introduces a decision support framework designed to assist healthcare managers, and clinical informatics specialists in analyzing and selecting the most appropriate consensus algorithm for their organization's blockchain-based health platforms, with a specific focus on managing pandemic-related information. Blockchain technology holds great potential in addressing pandemics by enhancing security and transparency in various aspects of pandemic tracking and mitigation while promoting public engagements by facilitating real-time exchange of electronic health information. By improving information sharing and coordination among healthcare organizations, it offers more effective response efforts and helps reduce the spread of viruses. However, the performance of consensus algorithms, which are a crucial component of blockchain architecture, can vary, posing a challenge in selecting the appropriate algorithm. To address this, the framework incorporates two techniques: data envelopment analysis (DEA) and the ranking distribution technique. DEA enables the analysis of efficiency without relying solely on expert judgment, providing a more objective assessment. The ranking distribution technique enhances differentiation among algorithms, providing decision-makers with a robust basis for selecting the most suitable blockchain architecture and its associated properties. The third paper focuses on the challenges of disseminating guidance-related information to the public during a pandemic, specifically the role of opinion leaders as reliable sources of information. The study determines the practical characteristics of pandemic opinion leaders on public attitudes using surveys and identifies domain-sensitive pandemic opinion leaders on Twitter based on the discovered characteristics using social network analysis and text mining. The framework's results show that pandemic opinion leaders are active in eight different domains on the Twitter platform. Results also demonstrate that trust is the most influential characteristic of pandemic opinion leaders, while expertise, uniqueness, innovation, and reputation also play important roles. / Doctor of Philosophy / This dissertation presents a collection of three research papers that offer insights and practical techniques and strategies to effectively tackle the challenges posed by pandemics through enhanced information sharing, public engagement, and robust public-private partnerships. The first paper introduces a novel mathematical model that thoroughly examines the collaboration between governments and humanitarian non-governmental organizations (NGOs) during crises such as the Covid-19 pandemic. The model's primary focus is on the equitable distribution of vital supplies, including face masks and shields, to healthcare workers as well as the public. By incorporating considerations of social costs, fairness, and other critical factors, this model aids managers in organizing the most efficient response to initial impacts of outbreaks within a short-term planning horizon. Our primary objective is to ensure the prompt and equitable delivery of essential supplies to individuals in need, achieved primarily through establishing strong public-private partnerships. The second paper proposes a decision support framework for healthcare managers, IT analysts, and clinical informatics specialists to help them effectively analyze consensus algorithms, as the most important layer of blockchain architecture. The framework further helps them select the most suitable algorithm for their organization's blockchain-based health platforms, aligning with specific policies, needs, requirements, and goals in managing pandemic-related information. Blockchain technology offers potential in tracking medical supplies, identifying virus hotspots, and verifying protective equipment authenticity to manage pandemics. By enhancing information sharing and coordination among healthcare organizations, blockchain can minimize virus spread and improve overall response efforts. The proposed framework reduces reliance on expert judgment and addresses data uncertainty when selecting proper algorithms for blockchain-based information management systems in mitigating the effects of pandemics. The third paper delves into the intricate challenges associated with effectively disseminating guidance-related information to the public during a pandemic, placing particular emphasis on the pivotal role played by opinion leaders (OLs) as reliable sources. This study thoroughly examines the distinctive characteristics of pandemic OLs and their profound influence on public attitudes. By employing surveys, social network analysis, and text mining techniques on Twitter data, the research successfully identifies OLs within distinct pandemic-related domains. The study's significant findings provide insights into the dynamic role assumed by pandemic OLs on Twitter and their consequential impact on public perception and behavior across various domains. Ultimately, the dissertation findings strive to support decision-makers and public health officials in their efforts to effectively manage pandemics and protect public health. The research emphasizes facilitation of seamless, rapid, and dependable information sharing across various planning horizons.
