The ways people go online have been transformed by the emergence of new mobile Internet technologies. As modes of Internet access are becoming increasingly diverse, this thesis sets out to examine how various forms of access shape engagement with online resources. Inequalities in Internet access have been neglected in the "second-level digital divide" research, which has focused on differences in skills and usage. Thus, I argue that inequalities of access have to be revisited and their role in digital inclusion reassessed. To study individuals' arrangements of Internet-enabled devices and locations holistically and as a dynamic entity, access is conceptualised as infrastructure. Theoretically, I distinguish between material dimensions of access and social practices shaping access, and draw on existing models of digital inclusion to examine the role of these dimensions and practices in online engagement. Empirically, a mixed methods research design is employed, complementing longitudinal analyses of survey data representative of the British population with 29 qualitative interviews with British Internet users. This study contributes to our understanding of material and social dimensions of access and their impact on Internet use patterns. First, the conceptualisation of Internet access as infrastructure is empirically validated. Second, quality, locality and ubiquity are established as material dimensions of access, where offline social and economic resources most strongly affect inclusion in high-quality, multi-local and ubiquitous Internet access. Third, three specific practices encompassing how users develop and maintain their access infrastructures are identified: spotlighting, distributing and being stranded. They reflect differences in roles Internet technologies play in individuals' daily lives as well as differences in availability of offline resources. Fourth, the results show that, controlling for a range of digital inclusion factors, the access inequalities have significant effects on a range of online engagement types, but are most strongly related to commercial and communication uses of the Internet. In sum, this study provides a nuanced understanding of how different mechanisms underlie the development, maintenance and engagement with Internet access, depending on whether access arrangements are shaped by digital exclusion or choice. Specifically, by outlining critical differences among all-round, mobile-mostly, mobile-only and home-only Internet users, broader policy and research implications are also discussed.

Os atletas de alto rendimento, como os jogadores de futebol, estão constantemente expostos nas redes sociais e isto pode se tornar uma armadilha, que possivelmente conduz a efeitos negativos no rendimento. Devido a este fator, é fundamental que as discussões sobre as novas mídias sociais online e suas influências nas emoções, estresse e enfrentamento de problemas sejam devidamente direcionadas, para que assim possamos compreender o fenômeno e auxiliar os atletas no manejo adequado das situações, favorecendo não só um bom rendimento, como uma melhor qualidade de vida e uma exposição menos nociva em um ambiente que possibilita a propagação descontrolada de qualquer postagem, mesmo que indesejada. Desta maneira, o objetivo foi analisar se as novas mídias sociais podem estar se tornando fatores causadores de estresse para os atletas profissionais de futebol que atuam na região de Rio Claro e as estratégias que utilizam frente a isto, procurando saber se estes consideram que são eficientes no enfrentamento.

The highperformance athletes, such as soccer players, are constantly exposed on social networks and this can become a trap, which could lead to negative effects on performance. Because of this factor, it is important that discussions about the new social media and their influence on emotions, stress and coping are properly addressed, and then we can understand the phenomenon and assist athletes in the proper management of situations, leading not only a good performance as a better quality of life and less harmful exposure in an environment that allows the uncontrolled spread of any post, even if unintended. Thus, the objective is to analyze if the new social media may become stressing factors for professional soccer players who act in Rio Claro and strategies using front of it, looking for whether they consider that are efficient in coping. For this, we used three questionnaires that met the objective of the study with a quantitative method, having as participants 35 professional soccer players, divided in competitive elite category and succesful elite. As a result, the total sample showed high involvement with social networks, and half of whom had problems with this. Among the groups, the competitive elite presented higher values in stress, in addition to being more important and challenging than the elite of success, which had higher numeric values of confrontation potential. In the emotions, the competitive elite obtained higher means in intensity and the elite of success in the direction, which shows that the competitive elite, besides having higher values of the emotions (especially anxiety), also ...

Thesis (MTech( Business Information))-- Cape Peninsula University of Technology, 2011 / Women, being important stakeholders of the community, are lagging behind in terms of economic empowerment. Their opportunity to participate actively in business in the past was hindered by various discriminatory policies that were in place. ICTs have the forte to empower and increase the knowledge base of the women in SMEs through information dissemination. The argument is that women in South Africa and indeed in many other developing countries have not embraced technology in their everyday businesses as much as their male counterparts. This study therefore explores how women in SMEs in the Cape Metropolitan, Western Cape are utilising ICTs to empower themselves to overcome the economic discrimination they have suffered in the past.In order to collect relevant data and obtain deep insights about the utilisation of ICTs by women in SMEs, a qualitative research method was applied enabling respondents to articulate their experiences concerning the use of ICTs in their businesses. Women of all races were selected using the snowball sampling method and were interviewed. The population involved women in SMEs from the five suburbs of Claremont, Rondebosch, Gardens, Pinelands and Mowbray.The findings of the study are that women in SMEs in the Cape Metropole are utilising various ICTs to empower themselves in their businesses. They are exchanging business documentation with other business resulting in marketing of their entities. Women in SMEs are taking advantage of the fast growing social and business networking technologies such Facebook, LinkedIn, Flickr, Twitter, Skype and blogs to promote marketing of their various products and services, gaining mileage in publicity and also managing their expenditures.ICTs enable women to work anytime, anywhere affording them the opportunity to take care of their families which they could not do while they were employed in the corporate world. Some of the women in SMEs reported that they can now independently negotiate business deals due to increase in their self-esteem and also have access to available information in their areas of expertise.

Orientadora: Rosa Monteiro Paulo / Resumo: Esta pesquisa tem como objetivo investigar, nas escolas da rede pública estadual de São Paulo, a atualização do Programa um Computador por Aluno (Prouca), ação de política pública que visa à inserção das tecnologias no ambiente escolar. A metodologia assumida foi a da pesquisa qualitativa em uma abordagem fenomenológica. O estudo inicia-se com leituras para conhecer o Prouca, quer seja no âmbito de sua proposta ou a partir de trabalhos que o tematizam. Tendo clareza do sentido do Prouca fomos às escolas entrevistar professores, gestores/diretores ou estagiário que o vivenciaram. As entrevistas foram gravadas e transcritas para serem analisadas seguindo os procedimentos da pesquisa fenomenológica que envolve a análise ideográfica, cuja intenção é explicitar o sentido que o Programa tem para cada um dos sujeitos entrevistados e a análise nomotética em que se expõe a compreensão geral do Prouca. Nesse movimento destacamos as Ideias Nucleares que convergem para três categorias abertas: Formação Humana, Infraestrutura Física e Infraestrutura Política que, ao serem discutidas, nos permite dizer dos modos de atualização do Prouca nas escolas consideradas / Abstract: This research has the objective to investigate in public schools of the state of São Paulo the update of the "One Computer Per Student Program (PROUCA)", a public policy which aims to insert technology in the school environment. The methodology of this researches qualitative with a phenomenological approach. The study begins with literature review for a first insight of PROUCA, whether it is in the scope of its proposal or of works approaching this theme. After studying the objective of PROUCA we went to schools to interview teachers, principals and interns that were related to the program. The interviews were recorded and transcribed to be analyzed according to the procedures of the phenomenological research which is composed by the idiographic analysis, whose aim is to explain the meaning of the program to each of the interviewed and the nomothetic analysis in which the general understanding of PROUCA is exposed. In this movement we highlight the Nuclear Ideas that converge to three open categories: Human development, Physical Infrastructure and Political Infrastructure, that, after the discussion, possibilitates us to say the update's means of PROUCA in the schools researched / Mestre

Diversas vezes, as premissas sob as quais estas soluções são propostas não poderiam estar mais longe das necessidades do mundo real. Um aspecto frequentemente esquecido, que pode influenciar em como a solução se sai ao ser integrada, é a forma como o usuário final interage com ela (i.e., fatores humanos). Neste trabalho, estudamos este problema através da análise de dois cenários de aplicação bem conhecidos da pesquisa em Segurança da Informação: O comércio eletrônico de itens digitais e Internet banking. Protocolos de trocas justas tem sido amplamente estudados, mas continuam não sendo implementados na maioria das transações de comércio eletrônico disponíveis. Para diversos tipos de itens digitais (e-goods), o modelo de negócios atual para comércio eletrônico falha em garantir justiça aos clientes. A validação de itens é um passo crítico em trocas justas, e recebeu pouca atenção dos pesquisadores. Nós acreditamos que estes problemas devam ser abordados de forma integrada, para que os protocolos de trocas justas possam ser efetivamente implementados no mercado. De forma geral, acreditamos também que isso seja um reflexo de paradigmas de projeto orientado a sistemas para soluções de segurança, que são centrados em dados em vez de usuários, o que resulta em métodos e técnicas que frequentemente desconsideram os requisitos de usuários. Contextualizamos como, ao subestimar as sutilezas do problema da validação de itens, o modelo atual para compra e venda de itens digitais falha em garantir sucesso, na perspectiva dos compradores, para as transações ¿ sendo, portanto, injusto por definição. Também introduzimos o conceito de Degradação Reversível, um método que inerentemente inclui o passo de validação de itens em transações de compra e venda com a finalidade de mitigar os problemas apresentados. Como prova-de-conceito, produzimos uma implementação de Degradação Reversível baseada em códigos corretores de erros sistemáticos (SECCs), destinada a conteúdo multimídia. Este método é também o subproduto de uma tentativa de incluir os requisitos do usuário no processo de construção de métodos criptográficos, uma abordagem que, em seguida, evoluímos para o denominado projeto de protocolos orientado a itens. De uma perspectiva semelhante, também propomos um método inovador para a autenticação de usuários e de transações para cenários de Internet Banking. O método proposto, baseado em Criptografia Visual, leva em conta tanto requisitos técnicos quanto de usuário, e cabe como um componente seguro ¿ e intuitivo ¿ para cenários práticos de autenticação de transações / Abstract: Designing secure cryptographic solutions from a purely theoretical perspective is not enough to guarantee their success in a realistic scenario. Many times, the assumptions under which these solutions are designed could not be further from real-world necessities. One particular, often-overlooked aspect that may impact how the solution performs after deployment is how the final user interacts with it (i.e., human factors). In this work, we take a deeper look into this issue by analyzing two well known application scenarios from Information Security research: The electronic commerce of digital items and Internet banking. Fair exchange protocols have been widely studied, but are still not implemented on most e-commerce transactions available. For several types of digital items (e-goods), the current e-commerce business model fails to provide fairness to customers. A critical step in fair exchange is item validation, which still lacks proper attention from researchers. We believe this issue should be addressed in a comprehensive and integrated fashion before fair exchange protocols can be effectively deployed in the marketplace. More generally, we also believe this to be the consequence of ongoing system-oriented security solution design paradigms that are data-centered, as opposed to user-centered, thus leading to methods and techniques that often disregard users¿ requirements. We contextualize how, by overlooking the subtleties of the item validation problem, the current model for buying and selling digital items fails to provide guarantees of a successful transaction outcome to customers, thus being unfair by design. We also introduce the concept of Reversible Degradation, a method for enhancing buy-sell transactions concerning digital items that inherently includes the item validation step in the purchase protocol in order to tackle the discussed problems. As a proof-of-concept, we produce a deliverable instantiation of Reversible Degradation based on systematic error correction codes (SECCs), suitable for multimedia content. This method is also the byproduct of an attempt to include users¿ requirements into the cryptographic method construction process, an approach that we further develop into a so-called item-aware protocol design. From a similar perspective, we also propose a novel method for user and transaction authentication for Internet Banking scenarios. The proposed method, which uses Visual Cryptography, takes both technical and user requirements into account, and is suitable as a secure ¿ yet intuitive ¿ component for practical transaction authentication scenarios / Doutorado / Ciência da Computação / Doutor em Ciência da Computação

O objetivo do estudo é investigar histórica e sociologicamente a forma pela qual o transtorno veio a ser investigado como uma patologia de origens biológicas pelas práticas psiquiátricas brasileiras. Para identificar os sentidos históricos pelos quais as fronteiras diagnósticas do transtorno possuem bases biológicas, foi feito um levantamento histórico para retomar as principais tradições da vertente organicista de pesquisa das doenças mentais da Psiquiatria no Brasil. Outro levantamento histórico buscou identificar, a partir do próprio conhecimento biológico do TDA/H, as contingências sociais do transtorno. A proposta de ambas as historiografias é investigar quais atores sociais mobilizaram técnicas e conhecimentos científicos oriundos da neurologia e da biologia até a sua atual classificação no Manual Diagnóstico e Estatístico de Distúrbios Mentais em sua quarta versão revisada - Diagnostic and Statistical Manual of Mental Disorders - DSM-IV/RT - e a Classificação Internacional de Doenças - CID-10. Em seguida, foi realizada uma investigação em artigos coletados na base científica SCIELO para identificar quais os principais atores sociais, as técnicas e o conhecimento científico que são mobilizados para investigar o TDA/H, entre os anos de 2007 e 2012, no Brasil. Foi possível verificar que, em sua maioria, o conhecimento da patologia é produzido por pesquisadores das áreas da Psiquiatria e das Neurociências que utilizam técnicas baseadas em paradigmas neurocientíficos para a investigação de doenças mentais. Interpreta-se que o conhecimento neurológico do transtorno, por sua vez, licencia que a prática médico-psiquiátrica trate determinados fenômenos sociais como problemas médicos e faça o controle social dos indivíduos desatentos "anormais" para recuperá-los em sua condição "normal". Acredita-se que investigações que utilizam o metilfenidato, principal fármaco da terapia da patologia, pode ser uma forma de controle social pela ciência psiquiátrica brasileira, quando definem os comportamentos através do conhecimento neurocientífico como TDA/H. Também foi possível constatar que os estudos sobre o TDA/H, em sua maioria, foram financiados por indústrias farmacêuticas, ator social hegemônico na produção do conhecimento científico do TDA/H. A relação entre indústria farmacêutica e produção científica é um meio de legitimar a administração do psicofármaco metilfenidato como terapia principal no tratamento do transtorno. Desta forma, a relação entre indústria e doença é um fenômeno social no qual a ciência possui papel preponderante na aferição das categorias que podem ser consideradas "doença" / Abstract: This dissertation aims to investigate the development of research on Attention Deficit-Hyperactivity Disorder (ADHD) in the organicist dimension of mental illness of psychiatry in Brazil, with the methodological approach of the Social Studies of Science and Technology (SSST), specifically the theoretical contribution of the social construction of illness. The objective of the study is to investigate historically and sociologically how the disorder came to be investigating with biological causes by Brazilian psychiatric practices. To identify the historical by which the boundaries of the disorder has a biological basis, a historical survey is done to resume the main research traditions of organicist shed of mental illness of Psychiatry in Brazil. Another historical survey seeks to identify the social contingences from the biological knowledge of ADHD. The proposal to investigate both historiographies is to analyses which social actors mobilized technical and scientific knowledge from neurology and biology to its current classification in the Diagnostic and Statistical Manual of Mental Disorders - DSM-IV/RT and the International Classification of Diseases (ICD-10). Then an investigation is carried out on the basis of scientific articles collected in SCIELO to identify the main social actors, the technical and scientific knowledge that are mobilized to investigate the ADHD, between 2007 and 2012, in Brazil. It was possible to verify, in most of the articles, that the knowledge of the pathology is done by researchers from the fields of Psychiatry and Neuroscience, which uses techniques based on neuroscientific paradigms for mental illness researches. It is interpreted that the neurological knowledge of the disorder, in turn, licenses the medical-psychiatric practices to treat certain social phenomenon as medical problems, under a social control of the individuals with the disorder treated as "abnormal" to get them back into their "normal" condition. It is proposed as an analysis that methylphenidate, the main drug therapy to the pathology, is a form of social control by Brazilian Psychiatry when they define the behaviors as ADHD. It also appeared that the studies are funded by pharmaceutical companies, the hegemonic social actor in the production of the scientific knowledge of ADHD. The relationship by the pharmaceutical industry and the scientific production is a way of legitimizing the administration of psychotropic drug methylphenidate as primary therapy in the treatment of the disorder. Thus, the relationship between industry and disease is a social phenomenon in which science has leading role in gauging the categories that can be considered disease / Mestrado / Politica Cientifica e Tecnologica / Mestre em Política Científica e Tecnológica

This thesis sets out to answer the following central research question: what are the influences, challenges, benefits and costs of the Central Admission System (CAS) as an e-Governance initiative in improving undergraduates’ admissions service delivery and quality assurance in Tanzania’s higher education institutions?’ In answering this key question, three sub-questions were explored: (1) To what extent and in what ways does the implementation of the CAS influence the organisation of admissions work and workplace relations in higher education institutions? (2) What are the sociotechnical challenges of implementing the CAS? (3) What are the advantages of the CAS in improving admissions service delivery and quality assurance in higher education institutions? The sociotechnical theoretical framework is an ideal for exploring these issues as it accommodates the understanding of dual relationship between social and technological aspects of the CAS in line with the contextual issues in its implementation. The focus of the thesis is on Tanzania’s higher education institutions where the CAS is being implemented. The study is informed by data collected through interviews and documentary analysis. Data organization and analysis was done using NVivo 10 QSR software. The study demonstrates that, notwithstanding the fast development and uptake of Information and Communication Technologies (ICTs), the implementation of the CAS in Tanzania is hampered by the fact that most of the end-users of CAS (particularly applicants) have relatively low access to the ICT infrastructure. Several factors continue to have a significant effect on the implementation of CAS, which in turn lead to implications for the uptake of improved admissions service delivery and quality assurance. A digital divide, resistance to change by some higher education institutions (HEIs), poor ICT skills among applicants, the costs of internet services, unreliable electricity supply, and inadequate IT experts continue to frustrate the objective of improved admissions service delivery and quality assurance. As a technological innovation in the workplace, the CAS has led to a restructuring of admissions work tasks among admissions officers, a need to review job descriptions, introduced tighter controls over admission work processes, and has shaped admission workers’ professional identities and self-presentations.

The Information and Communications Technology (ICT) skills shortage is of national and international concern. Modern business practices require the implementation of new technologies supported by a workforce with current and diversified ICT skill-sets. Acquiring suitable ICT skills has become a difficult task and employers are seeing government intervention at all levels. The school system in South Africa is under increased pressure and is faced with continuously declining matriculation pass rates, specifically in subjects such as science and mathematics. Schools are experiencing a decline in the number of scholars (learners) enrolling for the Information Technology (IT) school curriculum. The IT curriculum at school level is being criticised; under-prepared teachers are blamed and lack of suitable facilities highlighted. Surveys conducted amongst grade 9 and grade 12 scholars in the Eastern Cape have shown that scholars are not considering careers in ICT. Teachers, career/guidance counsellors and parents contribute to scholars' career decisions and are not encouraging scholars to pursue careers in ICT. Tertiary institutions in South Africa and internationally, are experiencing a decline in student enrolments and in pass and throughput rates. Industry is holding tertiary institutions responsible for not providing the “correct” ICT graduate skill-sets and passing an insufficient number of quality ICT graduates desperately required by industry. The accreditation of computing degree programs, such as Computer Science (CS), Information Systems (IS) and Information Technology (IT), collectively referred to as CIT, offered by tertiary institutions is becoming an international requirement. The ICT industry is constantly changing and new job requirements and new career opportunities are frequently introduced. Graduates entering the ICT industry should have acquired knowledge about ICT career tracks in order to specialise and choose a suitable career path. Tertiary CIT degree programs should further be linked to specific career tracks and provide a multi-disciplined education to graduates. ii ICT graduates working in industry utilise skills obtained in under-graduate and post-graduate CIT degree programs. The ICT graduates have also obtained valuable skills working in industry, including business skills and soft skills. ICT skill surveys have identified the graduate skills gap, indicating ICT skills industry requires from graduates completing tertiary level qualifications. ICT graduates working in industry, for example indicated that programming in some cases is over-emphasised at school and tertiary level and that soft skills are ignored by tertiary institutions. An ICT Graduate Skills Classifications Framework is developed to address the graduate ICT skills gap and highlight important business skills, soft skills, technical skills and programming skills required by industry. In this thesis, an Industry ICT Value Chain Model is further developed that suggests a holistic approach to the problems experienced at all levels of ICT skills development, including government, industry, tertiary education institutions and at school level. Results from a number of research surveys conducted along the proposed Industry ICT Skills Value Chain Model indicated that problems exist at all stages in the value chain and that the problems can only be addressed involving government, industry and tertiary institutions collectively. A number of interventions is required and the support from industry is essential in achieving overall success in addressing the ICT skills shortage in South Africa. A proposed Industry ICT Skills Value Chain Model that can be utilised to address the ICT skills shortage in South Africa is presented.
