Along with the smartphone’s increasing popularity around the world, there is an increasing development and popularity of power-hungry applications: applications that take advantage from these resources and may reduce the smartphones autonomy. This fact is known as one of the biggest to be solved when talking about nowadays smartphones. Considering this, many solutions were proposed and approach this topic in different ways. These solutions can be classified in two major groups: software layer solutions and hardware layer solutions. In one hand, the software layer solutions are the ones that try to reduce the smartphone’s energy drain by only changing the software that composes the smartphone. For example, by improving the Wi-Fi interface or managing the running applications of the smartphone. On the other hand, the hardware layer solutions are the ones that try to improve or increase the energy availability of the smartphone changing or improving only the physical components, for example evolving the technology regarding the batteries. This study presents an approach in software layer for this problem: a system for managing the states of the smartphone’s sensors and components, based on the user profile, aiming energy savings. This work consisted of three steps. In the first step the literature research was done and also a research of the existing solutions in the same area. In the second step the mechanism, called MyBatRecommender, composed by the server and client sides, was presented and developed for the Android operational system. In the last step some validation tests were applied aiming to verify the system efficiency. The results show that when applied to a controlled scenario, the MyBatRecommender achieves around thirty-two per cent of energy savings. / Os smartphones atuais são compostos por uma grande gama de sensores e componentes como GPS, Bluetooth e conexão com a Internet através das interfaces de rede Wi-Fi, 3G, entre diversos outros recursos. Junto com a crescente popularização dos smartphones ao redor do mundo está também o crescente desenvolvimento e popularização dos aplicativos que fazem uso desses recursos e tendem a diminuir a autonomia dos smartphones. Esse fato é considerado como um dos maiores problemas a ser superado no contexto de smartphones atualmente. Tendo esse problema em vista, diversas soluções abordam a questão de diferentes maneiras, e podem ser classificados em dois grupos: soluções em nível de software e soluções em nível de hardware. As soluções em nível de software são aquelas que procuram melhorar o consumo de energia dos smartphones apenas com alterações nos softwares que compõe o smartphone. Por exemplo, melhorando a eficiência da interface de rede Wi-Fi, controlando aplicativos que rodam no smartphone, entre outras. Por outro lado, as soluções em nível de hardware procuram melhorar ou ampliar a disponibilidade de energia nos smartphones através dos seus componentes físicos, como por exemplo evoluindo a tecnologia das baterias dos mesmos. Esta dissertação apresenta uma abordagem em nível de software para esse problema através de um sistema de gerenciamento dos estados dos sensores e componentes de um smartphone, baseado no perfil do usuário, visando a economia de energia. Esse estudo consistiu de três etapas. Na primeira etapa foi feito o levantamento bibliográfico e desenvolvida uma pesquisa de soluções existentes na área, identificando possíveis sistemas e aplicativos com a mesma proposição. Na segunda etapa foi elaborado o mecanismo denominado MyBatRecommender, composto pelas partes servidora e cliente, e implementado para o sistema operacional Android. Por fim, na última etapa, foram aplicadas algumas formas de validação no sistema proposto a fim de verificar a sua eficiência. Os resultados obtidos mostram que o sistema implementado, quando aplicado em cenário de testes controlado, apresenta um resultado que traz uma economia de energia de aproximadamente trinta e dois por cento em relação ao uso sem o mecanismo proposto.

Text in English with abstracts in English and Afrikaans / The objective of this study was to investigate how the integration of social media applications such as Facebook can be advantageous to students in Open Distance Learning (ODL) settings or environments. This study was carried out in the context and recognition that the use of social media has become a norm in modern-day society where people in general, and students in particular, can upload videos, images and texts towards achieving a common purpose. In order to achieve the objectives of this study, the researcher employed two theoretical frameworks, namely Connectivism and New Media Theory. The study also used Qualitative Research Methodology, particularly the qualitative content analysis research technique and focus group interviews. The study found that the use of Facebook provided students with better access to online resources and facilitated more interaction with fellow students. In an ever-changing world, the study established that technology has the potential to innovate distance learning, providing students with an open space to learn, collaborate and communicate more effectively. This means that social media applications have the power to connect people and bridge the gaps of time and distance. This is especially relevant in ODL environments where students operate in isolated spaces and have little or no direct interaction with their lecturers and fellow students. / Die doel van die studie is om ‘n ondersoek te loods na sosiale media integrasie, meer spesifiek Facebook, en hoe voordelig die gebruik daarvan vir studente in die konteks van ‘n Oop- en Afstandsonderrigleer (OAL) is. Die studie was gedoen binne die konteks, en met inagneming van, hoe die gebruik van sosiale media ‘n norm in die hedendaagse samelewing geword het, en hoe mense oor die algemeen videos, prente, en teks kan oplaai om ‘n gesamentlike akademiese doel te bereik. Ten einde die doel van die betrokke studie te bereik, het die navorser twee teoretiese raamwerke gebruik, naamlik Konnektivisme (Connectivism) en Nuwe media-teorie. Die studie het gebruik gemaak van ‘n kwalitatiewe navorsingsmetode, meer spesifiek kwalitatiewe inhoudsanalise en fokus-groep onderhoude. Die studie het bevind dat die gebruik van Facebook studente beter toegang tot aanlynhulpbronne verleen, en ook meer interaksie tussen studente bewerkstellig. In ‘n veranderende wêreld het die studie bevestig dat die gebruik van tegnologie oor die potensiaal beskik om innoverende afstandonderrig aan te bied en ope platforms vir studente bied om met mekaar saam te werk asook meer effektief te kommunikeer. Sosiale media beskik dus oor die vermoë om mense nader aan mekaar te bring, en ook die gaping van tyd en afstand te oorbrug. Dit is hierin ook die geval waar studente dikwels in isolasie, met min of geen direkte kontak met dosente of mede studente in ‘n OAL konteks, studeer. / Communication Science / M.A. (Communication Science)

Modeling the "thick description" of photographs began at the intersection of personal and institutional descriptions. Comparing institutional descriptions of particular photos that were also used in personal online conversations was the initial phase. Analyzing conversations that started with a photographic image from the collection of the Library of Congress (LC) or the collection of the Manchester Historic Association (MHA) provided insights into how cultural heritage institutions could enrich the description of photographs by using informal descriptions such as those applied by Facebook users. Taking photos of family members, friends, places, and interesting objects is something people do often in their daily lives. Some photographic images are stored, and some are shared with others in gatherings, occasions, and holidays. Face-to-face conversations about remembering some of the details of photographs and the event they record are themselves rarely recorded. Digital cameras make it easy to share personal photos in Web conversations and to duplicate old photos and share them on the Internet. The World Wide Web even makes it simple to insert images from cultural heritage institutions in order to enhance conversations. Images have been used as tokens within conversations along with the sharing of information and background knowledge about them. The recorded knowledge from conversations using photographic images on Social Media (SM) has resulted in a repository of rich descriptions of photographs that often include information of a type that does not result from standard archival practices. Closed group conversations on Facebook among members of a community of interest/practice often involve the use of photographs to start conversations, convey details, and initiate story-telling about objets, events, and people. Modeling of the conversational use of photographic images on SM developed from the exploratory analyses of the historical photographic images of the Manchester, NH group on Facebook. The model was influenced by the typical model of Representation by Agency from O'Connor in O'Connor, Kearns, and Anderson Doing Things with Information: Beyond Indexing and Abstracting, by considerations of how people make and use photographs, and by the notion of functionality from Patrick Wilson's Public Knowledge, Private Ignorance: Toward a Library and Information Policy. The model offers paths for thickening the descriptions of photographs in archives and for enriching the use of photographs on social media.

Indiana University-Purdue University Indianapolis (IUPUI) / Instrument assisted soft tissue mobilization (IASTM) is a form of massage using rigid manufactured or cast devices. The delivered force, which is a critical parameter in massage during IASTM, has not been measured or standardized for most clinical practices. In addition to the force, the angle of treatment and frequency play an important role during IASTM. As a result, there is a strong need to characterize the delivered force to a patient, angle of treatment, and stroke frequency. This thesis proposes two novel mechatronic designs for a specific instrument from Graston Technique(Model GT3), which is a frequently used tool to clinically deliver localize pressure to the soft tissue. The first design is based on compression load cells, where 4-load cells are used to measure the force components in three-dimensional space. The second design uses a 3D load cell, which can measure all three force components force simultaneously. Both designs are implemented with IMUduino microcontroller chips which can also measure tool orientation angles and provide computed stroke frequency. Both designs, which were created using Creo CAD platform, were also analyzed thorough strength and integrity using the finite element analysis package ANSYS. Once the static analysis was completed, a dynamic model was created for the first design to simulate IASTM practice using the GT-3 tool. The deformation and stress on skin were measured after applying force with the GT-3 tool. Additionally, the relationship between skin stress and the load cell measurements has been investigated. The second design of the mechatronic IASTM tool was validated for force measurements using an electronic plate scale that provided the baseline force values to compare with the applied force values measured by the tool. The load cell measurements and the scale readings were found to be in agreement within the expected degree of accuracy. The stroke frequency was computed using the force data and determining the peaks during force application. The orientation angles were obtained from the built-in sensors in the microchip.

This thesis is an exploration of tabooed literary creations that it terms carnival literature. To achieve the objective of establishing the effectiveness of posting material on Facebook walls of the selected group and individual accounts to escape censorship, the thesis compared traditional graffiti, particularly latrinalia, to ‗cyber‘ graffiti (social media) with Facebook as a case study. Lev Vygotsky‘s Activity Theory helped the study link graffiti, vulgarities, humour and Facebook to the Ndebele society‘s response to tabooing of carnival literature. The thesis argued that participating in traditional graffiti production and coming up with posts on a Facebook wall is a deliberate effort with a target audience just as other genres of literature have. However, society tends to condemn carnival literature as a rebellious genre that deserves exclusion from ‗normal‘ interaction. Carnival literature is therefore censored through tabooing its themes and language. The term carnival literature is derived from medieval performances that were named the ‗carnivalesque‘ by Bakhtin and have equivalents in Africa as a continent and in Zimbabwe as a nation. The characteristics of carnivality are found in both traditional graffiti and ‗cyber‘ graffiti. These, among others, include sex and sexuality as themes, obscenities, vulgarities, and all language that is considered offensive. Interestingly, these elements of carnivality evoke laughter of one kind or another. Latrinalia from selected public toilets from the city of Bulawayo was photographed and subjected to Critical Discourse Analysis with attention being paid to carnivality, Bakhtinian dialogism and humour and its impact on the interaction process. Posts on walls of the selected Facebook group and individual accounts were subjected to the same treatment that was given traditional graffiti. The thesis argues that social media can perform a similar function to that of traditional graffiti with added advantages. Social media has created world communities that are brought together by common interests and platforms where they meet and share ideas. The study also established that messages have layers of meaning, making it unreasonable to ban certain messages since they serve a particular purpose. Social media, particularly Facebook, provides pockets of privacy for candid and unfettered interaction that service specific audiences among the Ndebele; hence can function as the escape route for carnival literature from cultural censorship in Zimbabwe. / African Languages / D.

Indiana University-Purdue University Indianapolis (IUPUI) / Nurse-physician collaboration has received much attention over the past decade in the USA. The release of three reports from the Institute of Medicine implicated poor communication and collaboration among nurses and physicians as a major contributing factor to the incidence of sentinel events and medical errors. Despite the growing awareness of the imperative related to collaboration between nurses and physicians to ensure patient safety, the problem of poor nurse-physician collaboration remains endemic throughout the country. Indian nurses, along with many other internationally educated nurses, comprise 12-15.2% of the nursing workforce in the USA. Little is known about how Indian nurses culture potentially influences their ability to effectively collaborate with physicians to ensure patient safety. The purpose of this study is to understand Indian nurses’ attitudes and perceptions about nurse-physician collaboration. Hermeneutic interpretive phenomenology as influenced by the work of Martin Heidegger guided this study through the use of interviews via Skype. The overall experience of the Indian nurses was of one experiencing a dramatic positive change in nurse-physician collaboration in the USA as compared to India. Four themes emerged describing this phenomenon: Respect/feeling heard, Being Trusted, Assurance of Accountability, and Finding Freedom. Indian nurses practicing in the USA find a freedom that empowers them to collaborate with physicians for patient safety. They, as all nurses may, benefit from continuing educational opportunities that demonstrate ways to collaborate more fully.
