In 2016, over 11 million people misused prescription opioids and the economic costs were estimated to be over $500 billion. In the same year, opioids killed 42,000 people, which was more than any year on record. These data highlight the need to reduce the harm caused to individuals, families, communities, and the nation. One element of a more comprehensive national strategy is increasing awareness among citizens, physicians and policy makers. Given its widespread reach YouTube can be very helpful. There is a large literature on the opiate epidemic, but no published studies describing the sources or content of YouTube videos on the opiate epidemic were identified. This study was, therefore, intended to help fill this gap in current knowledge. YouTube was searched using two key terms, “opiate addiction” and “opioids.” The results were sorted by number of views, and the URL, title, and number of views were saved for videos with a minimum of 1,500 views. Videos were then screened for the inclusion and exclusion criteria. The remaining sample comprised 309 videos. Collectively, these 309 videos were viewed 44,693,887 times. The results revealed the sources that were most viewed and the nature of content that was and was not likely to be covered. The two main sources of videos were Internet Based and Television news/Entertainment. Compared with videos with health professions as the main speaker, those featuring consumers garnered almost 10 times as many cumulative views (30.35%versus 3.24%). Government organizations uploaded 11 videos (< 4%), collectively garnering 343,983 views (less than 1% of cumulative views). YouTube represents an important opportunity for health promotion and disease prevention regarding the opiate epidemic. However, improved understanding about ways to communicate accurate and useful information in ways that attract viewers is needed. Recommendations for research, policy and practice are presented relevant to how YouTube can help mitigate the harm caused by the opiate epidemic.

M. Tech. Business Information Systems / Knowledge Management is an increasingly important driver in today's economy which functions mainly on knowledge. In view of that, knowledge is valuable asset for an organization to sustaining competitive advantage. The challenge faced by organization is the loss of critical organizational knowledge held by employees who are departing due to circumstances such as retirement, termination of contracts, resignation and transfer. This challenge is further aggravated by the lack of capturing and preserving knowledge before experienced employees depart from the organization. The purpose of this study is to assess the effectiveness of SharePoint in the public sector as a tool for Knowledge Preservation. The objectives of the study were; to determine the use of SharePoint in the public sector; the processes used to preserve the knowledge within the public sector; the benefits of using SharePoint for Knowledge Preservation; the challenges of using SharePoint for knowledge preserving and the factors for effective use of SharePoint as a tool for preserving knowledge.

This study examines information disclosure of Facebook users in America and Kenya. The main aim of this study is to find out the specific type of personal and demographic information that individuals disclose on their profiles. The literature review details the nature of social networking sites highlighting studies that have been carried out in the past on these sites. Self-disclosure is also discussed as described in the social penetration theory. An overview of the practice of public relations profession in Kenya is also given. The research study employs the content analysis methodology, with a total of 500 Facebook profiles being analyzed. Results of this study indicate that users disclose a lot of information on their Facebook profiles such as the use of a self-portrait as the main identifying mark on their profiles, their dates of birth, personal information such as religious and political views and education and work information. There are also major gender differences in information disclosure. There are also differences in information disclosure on Facebook between American users and Kenyan users. / Department of Journalism

This thesis examines how Baby Boomers utilize Facebook to promote radical political ideology. A convenience sample of 51 Baby Boomer Facebook profiles were selected and critically analyzed for radical content using Bernard L.Brock’s (1965) A Definition of Four Political Positions and a Description of their Rhetorical Characteristics, and Making Sense of Political Ideology: The Language of Democracy (Brock, et al., 2005). The rhetoric from these profiles was then categorized using James W. Chesebro’s (1972) Rhetorical Strategies of the Radical Revolutionary. Conclusions from the research indicate that radical Boomers on Facebook seem to have moved from real world activism to symbolic action on Facebook through the liking and sharing of radical articles and posts. Though consistent in posting radical content in their profiles, radical Boomers using Facebook in this study utilized profiles more to promote radical culture online than to foment political revolution offline. / Department of Telecommunications

This study implemented an experimental introductory CS course for non-CS majors focusing on two pedagogic factors: 1) the use of a visual blocks programming language known as App Inventor for Android (AIA) and 2) the adoption of SBL as the main teaching methodology. Participants included 30 undergraduates enrolled in two introductory CS courses; the experimental course (CS116) and a traditional lecture oriented CS course. The Motivated Strategies for Learning Questionnaire (MSLQ) was implemented in both courses at several stages. Statistically significant differences were found in the Control of Learning Beliefs, Help Seeking, and Intrinsic Motivation scales, were CS116’s participants scored higher rates. In CS116, entry and exit interviews were conducted as well as a mind maps analysis. Their results showed a positive response to the pedagogic factors, positive attitudes towards CS, and an improvement in the understanding of CS. The majority of participants did very well and showed creativity with not one student failing the course. They found the experimental course to cultivate collaboration, creativity, and motivation to learn. The experimental approach was found have a positive effect on students’ motivation, achievement, and attitude towards CS. / Department of Computer Science

O aplicativo foi desenvolvido com a linguagem de programação orientada a objetos Java, no ambiente de desenvolvimento Eclipse. Esse aplicativo possibilita armazenar e visualizar informações de voluntários, como dados pessoais e medidas de força na região plantar de pacientes. Para a transmissão dos dados do baropodômetro foi desenvolvida uma instrumentação constituída por uma plataforma Arduino, um dispositivo PSoC, um módulo Bluetooth, um amplificador de instrumentação, um multiplexador, reguladores de tensão e potenciômetros. Utilizando o sistema implementado foi possível observar nitidamente diferenças na distribuição da descarga de peso na região plantar de voluntários hígidos e de voluntários com escoliose. Os resultados obtidos evidenciaram que os pacientes com escoliose descarregam de forma mais desigual os pesos nos pés direito e esquerdo que os pacientes hígidos. A maior diferença no percentual de descarga de peso entre os pacientes com escoliose e os hígidos ocorreu no médio pé, que nos pacientes com escoliose é menos da metade da que ocorre nos pacientes hígidos / An application for the Android operating system that performs data acquisition of a baropodometer via Bluetooth to support the analysis of scoliosis by health care professionals was implemented. The application was developed with Java object oriented programming language in the Eclipse development environment. This application allows storing and displaying informations of volunteers, such as personal data and mensurements of force in the plantar region of patients. For the transmission of the barapodometer data, an instrumentation built with an Arduino platform, a PSoC device, a Bluetooth module, an instrumentation amplifier, a multiplexer, voltage regulators and pots was used. Using the implemented system, we can clearly see differences in the distribution of weightbearing in the plantar region of healthy volunteers and volunteers with scoliosis. The results showed that patients with scoliosis unload more unequally weights on the right and left feet that healthy patients. The biggest difference in the percentage of weightbearing in patients with scoliosis and healthy occurred in the midfoot. In patients with scoliosis, in this plantar region, the percentage of weightbearing is less than half of that in healthy patients

This study aimed at assessing access and use of PERii electronic journal resources by postgraduate students in the School of Education at the University of Dar es Salaam. Specific objectives for this study were to examine if the postgraduate students in the School of Eduction are aware of PERii electronic journal resources; to examine if the postgraduate students access PERii electronic journal resources; to examine if the postgraduate students use PERii electronic journal resources; to examine the challenges encountered by postgraduate students in the access and use of PERii electronic journal resources; and to determine possible ways to improve access and use of PERii electronic journal resources. The study was basically a cross-sectional study and data were collected through a combination of questionnaire for postgraduate students and interview for the Reference Librarians. The findings of this study were that the majority of postgraduate are aware of PERii electronic journal resources through various sources including the Library website, notice board, fliers, posters, IL training, colleagues, librarians and supervisors. Again, the majority of them use PERii electronic journal resources for various purposes including working on the assignments, research proposal writing, literature review, research report writing, current awareness, leisure, and for extra exploration of ongoing scientific debates through peer reviewed papers. The challenges encountered include power outage, inadequate bandwidth, slow download speed, inability to access the resources from home, lack of training, lack of awareness, limited access to computers and difficult in making a search. Suggested ways to improve access and use of PERii electronic journal resources include seeking to provide training on how to access and use of PERii electronic journal resources; ensure stable and reliable power, ensure adequate bandwidth; increase awareness of the resources, improve ICT infrastructure, enable access of the resources from home; increase download speed and ensure relevant information is provided. Based on these findings it was recommended that training on access and use of PERii electronic journal resources should be integrated into the University curriculum; ICT infrastructure to support access and use of PERii electronic journal resources should be improved; ensuring stable and reliable power by buying heavy duty generators at the University; increasing awareness by improving methods for promotion and marketing of the resources; enabling access of PERii electronic journal resources from home; ensuring adequate bandwidth through shaping the available bandwidth allowing certain services such as ICT services to receive a large proportion of bandwidth than other services; and ensuring relevant information is provided through subscribing more database with relevant information to all courses at the University. / Mini Dissertation (MIT)--University of Pretoria, 2015. / Information Science / MIT / Unrestricted
