Master of Science / Department of Family Studies and Human Services / Karen Myers-Bowman / Today more and more teenagers are adopting cell phone communication as the primary way to communicate with their peers and parents (Lenhart, Ling, Campbell, & Purcell, 2010). Literature is vast on the negative use of cell phones by teenagers such as sexting and bullying (e.g., Draper, 2012) and on the negative implications it has on them and their relationships with peers (e.g., D'Antona, Kevorkian & Russom, 2010). However, it is very limited in exploring how cell phone use affects parent-adolescent communication. To investigate this question, ten parent-adolescent dyads who have used cell phones for more than six months participated in 25-40 minute interviews consisting of 14 open-ended questions about how they use cell phones to communicate. The teenagers’ ages ranged from 14 to 18 years of age and the average age of the teenagers was 16.6 years. Transcripts of interviews were analyzed for main themes. I found that parents and teenagers text each other more than call each other. They use cell phones to communicate for practical reasons, such as safety/checking in with each other, as well as for relational reasons, such as staying in touch with each other at a distance and sharing fun information with each other. These devices help the parents and adolescents be available to each other, facilitate quick yet flexible response times, and allow parents to teach responsibility. However, they also face challenges of overuse, which can hinder parent-adolescent communication, and can lead to miscommunication. The results of this study can be used by Family Life Educators to help new parent and teen cell phone users to learn about the benefits of cell phones as well as some of the expected challenges and help them get the most out of their cell phone communication.

Copper cable theft (CCT) has a devastating effect on the South African economy, and essential services such as TELKOM, ESKOM AND TRANSNET have been seriously disrupted, due to CCT. This dissertation focuses on the value of the cell phone record as a source of intelligence during (CCT) investigations. The cell phone industry is growing each year, and millions of people worldwide possess a cell phone. Some of these people are involved in criminal activities – which mean that cell phones, with their advanced capabilities, hold evidence which relates to crime. The activation of cell phone activity is contained on a cell phone record, and, when analysed, such information becomes intelligence which has a positive impact on CCT investigations. The purpose of this study is to assist and give guidance to investigators, in order to analyse the cell phone record(s) of CCT thieves. / Criminology and Security Science / M. Tech.

Thesis (MBA (Business Management))--University of Stellenbosch, 2009.

<p>This thesis examines the relationship between work/life balance and Smartphones (Blackberry, iPhone, Android etc.)</p><p>Academic research has areas where not much research has been done previously including the qualitative research on work/life balance, positive crossover of work/life balance, newness of Smartphone technology, and consequences of constant connectivity. This study hopes to eliminate some of the gaps in these areas of research and proposes two research questions:  <strong>So what does owning a Smartphone mean for work life and home life?  Most importantly can this phone help people towards or assist with the balance they are so looking for or do the phones not impact this balance and just assist in the work life and home life realms separately?</strong></p><p>A qualitative approach using constructionist and interpretivist views were used to conduct the research. Empirical material was collected during phone interviews with participants in the USA, while supporting material was gathered from conference papers, academic articles, websites, and textbooks.</p><p>There are two major themes within this paper, work/life balance and Smartphone technology. For work/life balance a common understanding was reached that work and personal life should be kept happy but that doesn’t mean equal.  Also discussed is research about people that put up boundaries in their lives to try and separate things, one group of people likes to have work and personal separate but one group likes them combined.  Research also presents that there are consequences for setting up boundaries but that having the ability to choose where these boundaries are makes for a much happier situation.  On the technology side of research there is support for these devices being used to manage people’s different selves through communication from being more connected to people to feeling left out when the technology is not there. Also mentioned is how people adapt the devices to fit new and unique situations that the devices may not have been intended to be used for.</p>

A research report submitted to the Faculty of Commerce, Law and Management, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Management specialising in Entrepreneurship and New Venture Creation. Wits Business School, University of the Witwatersrand, Johannesburg (March 2017) / Innovation is one of the core and key characteristics of entrepreneurship, which stimulates operational and financial success of a firm. Innovation is ambidextrous in nature, characterised by exploration and exploitation. This report is concerned with exploitative innovation, which is characterised by new; products, services, and processes. This Research Report investigates how human capital investments (years of schooling and years of work experience of telecoms firms’ senior managers and executives) relate to innovation performance. This paper uses the human capital theory and the resource base theory to understand the perceived impact of human capital investments on performance and also its perceived moderation effect on the nexus between innovation and performance. Research findings from 81 senior management and executives of four major telecoms firms in South Africa indicate that innovation has a perceived direct impact on the perceived success of the firm. However, a counterintuitive relationship of human capital investments with performance is observed. Furthermore, human capital investments have a counterintuitive moderating effect on the nexus between innovation and performance. Therefore, this research report discusses human capital variable configurations that are more likely to have a perceived impact on a telecoms firm performance, and human capital variable configuration that are likely to have a moderating effect on the nexus between innovation and performance. / MT2017

[pt] Jesus Cristo, Príncipe da paz é um estudo teológico do tema da paz bíblica, cuja chave de leitura é sua relação com a pessoa e a mensagem de Jesus Cristo, e que apresenta, em linhas gerais, as exigências evangélicas de uma ética e de uma ação pastoral comprometidas com a construção da paz. O interesse em estudar a paz bíblica encontra seu fundamento no fato de que a paz, um desejo dos diversos povos em todos os tempos e lugares, está presente no texto da Bíblia, naquilo que ela nos testifica sobre a relação entre Deus e a humanidade, bem como sobre o seu projeto salvífico. A partir da análise de certos textos do Antigo e do Novo Testamentos, este trabalho busca sistematizar toda a riqueza e complexidade do tema da paz bíblica. Seu objetivo principal é mostrar como que o evento Jesus Cristo dá uma nova dinâmica a esse tema. Em sua pessoa e em sua mensagem está o sentido pleno do que seja a paz bíblica, já que ela está inserida na própria dinâmica da Revelação da face de Deus Pai, assim como no anúncio e na instauração do seu Reino. Desta maneira, esta dissertação mostra que uma teologia e uma ética cristã da paz encontram seus fundamentos na pessoa e na mensagem de Jesus Cristo. / [en] Jesus Christ, the Prince of Peace, is a theological study of the theme of the Biblical peace, centering on its relationship with the person and the message of Jesus Christ. It summarizes evangelical requirements of an Ethics and of a pastoral action committed to the building of peace. The interest in the study of Biblical peace has its foundations on the fact that peace - a desire of the various peoples throughout history - is present in the Biblical texts when they speak of God`s relationship to humanity and of His salvation project. Departing from an analysis of certain texts of the Old one the New Testament this work tries systemize all the richness and complexity of the theme of Biblical peace. Its main objective is to show how the event Jesus Christ gives a new meaning to this theme. In His person and in His message rests the full meaning of what Biblical peace is, since it is contained in the very process of the Revelation of the face of God, the Father, and in the announcement and establishment of His Kingdom as well. In this fashion, this dissertation shows that a Theology and a Christian Ethics of peace have their foundation on the person and on the message of Jesus Christ.

A população idosa cresce no Brasil e cada vez mais se faz necessário desenvolver tecnologias de informação e comunicação adequadas a esse público. Com o barateamento dos telefones celulares, muitas famílias gostariam que seus idosos fossem usuários desses dispositivos visando ter contato com os mesmos quando esses estão fora de suas casas. No entanto, o design atual de celulares privilegia o público jovem, não levando em consideração as diferentes necessidades da população idosa. No mais, mesmo na população idosa, há diferenças com relação à escolaridade, experiência com tecnologias, habilidades cognitivas e destreza física. Este trabalho argumenta a favor do design, da implementação e da avaliação de interfaces que sejam flexíveis para atender à diversidade de requisitos dos idosos na interação com celulares. Uma abordagem para o design de interfaces de usuário flexíveis foi aplicada em um experimento exploratório e, considerando-se resultados de uma atividade estudo empírico com usuários idosos, um conjunto de normas que definem o design do comportamento flexível do sistema foi especificado. Esta dissertação propõe e apresenta um framework que propicia a reconfiguração de interfaces em tempo de interação, denominado de FlexInterface. Esse framework aborda o conceito de elementos da interface sendo, componentes que são carregados, instanciados e destruídos quando solicitados. Além disso, esta dissertação apresenta também uma abordagem que apoia a avaliação de interfaces flexíveis para idosos em telefones celulares. A abordagem analítica proposta, apresenta heurísticas específicas para esse contexto de uso. Por fim, uma avaliação com idosos foi realizada para verificar a viabilidade da proposta. Esse estudo constatou que houve uma redução no tempo de interação com o uso da interface flexível e um aumento na satisfação do usuário / The elderly population grows in Brazil and this fact increases the need to develop appropriate information and communication technologies to the public. As cell phones are getting cheaper, many families would like their elderly to be users of these devices aiming to have contact with them when they are out of their homes. However, the current cell phones design favors the younger people, not considering the different needs of the elderly population. At the most, even in the elderly population, there are differences regarding education, experience with technology, cognitive abilities and physical prowess. This dissertation argues for the design, implementation and evaluation of interfaces that are flexible to meet the diverse requirements of the elderly in the interaction with cell phones. One approach to the design of flexible user interfaces was applied in a case study and, considering the results of a practice with elderly users, a set of norms which define the design of the system flexible behavior was specified. This dissertation proposes and presents a framework that provides the interface reconfiguration during the interaction time, named FlexInterface. This framework addresses the concept of interface elements as components that are loaded, instantiated and destroyed when requested. Furthermore, this dissertation also brings an approachthat supports the evaluation of flexible interfaces for the elderly in mobile phones. The proposed analytical approach presents heuristics for this specific context of use. Finally, an assessment with elderly people was performed to verify the feasibility of the proposal. This study found that there was a reduction in the interaction time with the use of flexible interface and an increase in the users satisfaction

The early obsolescence of electronics because of technological advances and the growth of sales volume of mobile phone including the informal sector contribute to increase the amount of waste generated. Disposal of mobile phone batteries in household waste represents loss to the environment, because of toxic elements composition, if are accommodated in landfills or land, represent health and environmental impact causing the contamination of people, animals, and ground sheets water tables. The Brazilian legislation defines shared responsibility for the lifecycle of the product and reverse logistics as a tool for reducing environmental impact. In this context, this study aims to evaluate the knowledge of the mobile phone vendors in the informal market about environmental legislation for disposal of batteries, diagnose the social responsibility of those vendors related to hazardous wastes and finally, identify if there practice of reverse logistics process. The methodology used was Case Study in degree compared between two popular markets managed by the private entity and the government office. The research is exploratory and descriptive order through a literature review and field research. The respondents for the research were the sellers of mobile phone that working in two popular markets and the data were collected through semi-structured interview. The results show that there is little consumer participation in the process of discarding cell phone batteries that 100% of the respondents have no knowledge about the legislation for disposal of cell phone batteries and that vendors don t have co-responsible behave in the reverse logistics process for the environmentally disposal of cell phone batteries. Therefore, it is recommended environmental education as a tool to give information to promote change in the behavior of users and mobile phone vendors in the informal market in Goiânia. / Um dos problemas ambientais mais graves é o manejo adequado dos resíduos sólidos. A obsolescência precoce dos produtos eletrônicos em razão do avanço tecnológico e o crescimento do volume de venda de telefone celular, inclusive no mercado informal, contribuem para aumentar a quantidade de resíduos gerados. O descarte de baterias de celular em lixo domiciliar representa prejuízo ao meio ambiente, pois estas, devido à composição de elementos tóxicos, se acomodadas nos aterros sanitários ou no solo, provocam impacto ambiental, causando a contaminação de pessoas, animais, subsolo e lençóis freáticos. A legislação brasileira prevê a responsabilidade compartilhada pelo ciclo de vida do produto e a logística reversa como instrumento para mitigar impactos ambientais negativos. Nesse contexto, o trabalho tem por objetivo avaliar o conhecimento que os vendedores de telefone celular do comércio informal têm sobre a legislação ambiental para descarte de baterias, visando diagnosticar a responsabilidade social deste vendedor quanto ao destino dos resíduos perigosos e, por fim, identificar se há prática do processo de logística reversa. A metodologia utilizada foi o Estudo de Caso em grau comparativo entre dois centros de comércio popular administrados por ente privado e pelo poder público. A pesquisa tem fim exploratório e descritivo por meio de levantamento bibliográfico e pesquisa de campo. Os sujeitos da pesquisa foram os vendedores de telefone celular que trabalham nos dois centros de comércio popular e os dados foram coletados por entrevista semi-estruturada. Os resultados apontam que existe pouca participação do consumidor no processo de devolução das baterias, que 100% dos entrevistados não têm conhecimento sobre a legislação de descarte de baterias e que os comerciantes não têm comportamento corresponsável no processo de logística reversa para a destinação final ambientalmente adequada das baterias de celulares. Diante disso, recomenda-se a educação ambiental como instrumento de informação para promover a mudança de comportamento dos usuários e vendedores de telefone celular do mercado informal de Goiânia.
