Nesta dissertação, são discutidas as vantagens e dificuldades de um Sistema Gerencial de Apoio a Decisão em um ambiente Intranet/Internet, sua execução, bem como a utilização de aplicações de bancos de dados na web. Um sistema dessa natureza, denominado SAG (Sistema de Apoio Gerencial), foi concebido para dar suporte às atividades de gerência, supervisão e controle da rede de distribuição de energia elétrica da Eletropaulo Metropolitana (São Paulo, Brasil). O SAG possibilita o estabelecimento de uma sistemática de supervisão, visando, a partir da análise das condições atuais da rede de distribuição e em função dos recursos disponíveis, permitir o acompanhamento da evolução da qualidade do fornecimento de energia elétrica. Disponibilizando informações que irão orientar ações para corrigir os possíveis desvios inadequados e fixar políticas e diretrizes a serem seguidas nos níveis gerenciais. Como resultado, é esperado tornar mais ágil o processo decisório, bem como o acesso a dados técnicos e de carregamento dos equipamentos da rede de distribuição. / In this dissertation are discussed the advantages and difficulties of an Executive Information System (EIS) implementation on an Intranet or Internet environment, as well as the use of Database applications on the web. An Executive Information System named SAG was implemented at Eletropaulo Metropolitana (São Paulo, Brazil); it was conceived to address maintenance, operational and engineering departments\' needs. The System allows the establishment of a systematic supervision to attend the quality of the electric energy supplied. The analysis of the actual distribution network conditions, the available resources and the electric energy supplied quality will guide the actions to correct possible inadequacies as well as set and fix policies and guidelines to be followed on a manager\'s level. As a result it\'s expected faster decision-making process and access on distribution network equipment\'s technical data and load.

The people whom participated of this research were students of a fundamental cycle s recover class with huge cognitive problems, including difficulties with use of basic operations with integers. The methodological approach, in an ample sense, used the principles of Didactic Engineering and qualitative research techniques, as contents analysis, in order to analyze, by Didactic Situations Theory perspective, the protocols produced by students from three research instruments. The interfaces of these instruments were planned to use pencil and paper, calculators and the Geogebra software. The pedagogical strategy adopted allowed to the students understand the rule of signs and the concept of the symmetric of an integer number, using it to improve their own performance related to operations on integer numbers. Moreover, during the investigation, the students could develop the autonomy and the capacity to reflect about the errors made by them, which allowed rebuilding the strategies planned earlier. More than simply provide answers to arithmetic operations, the students could to understand its real meaning / Este trabalho de pesquisa teve como objetivo verificar em que medida uma estratégia pedagógica com o uso de tecnologias diversas, tanto as tradicionais como aquelas conhecidas como TICs, poderia fomentar a aprendizagem dos conceitos envolvidos nas chamadas regras de sinais quando utilizadas em conjunto com as operações aritméticas. Os sujeitos desta pesquisa foram os alunos de uma turma de recuperação de ciclo II do Ensino Fundamental II os quais apresentavam enormes defasagens cognitivas, inclusive no que se refere às operações básicas com números inteiros. A abordagem metodológica, de caráter amplo, valeu-se de pressupostos da Engenharia Didática e de técnicas de pesquisa qualitativa, como a análise de conteúdo, para analisar, à luz da Teoria das Situações Didáticas, os protocolos produzidos pelos sujeitos a partir de três instrumentos de pesquisa, cujas interfaces previam, respectivamente, o uso de lápis e papel, o uso de calculadoras e o uso do software GeoGebra. A estratégia pedagógica adotada permitiu que os estudantes compreendessem, para além das chamadas regras de sinais , o conceito de simétrico de um número inteiro, empregando-o para melhorar o próprio rendimento em relação às operações no âmbito deste conjunto. Além disso, no decorrer da investigação, os estudantes puderam desenvolver a autonomia e a capacidade de refletir sobre os erros cometidos, refazendo as estratégias que permitiam, mais do que simplesmente fornecer uma resposta a uma operação aritmética e entender o seu significado intrínseco

The aim of this research is to evaluate the process and impact of outsourcing information technology (IT) services of Eastern Cape Treasury Department (ECTD) to State Information Technology Agency (SITA). This research study has been prompted by the fact that the South African Government through the National Department of Public Service and Administration has established SITA with a sole purpose of improving service delivery by all national, provincial and local government departments. The researcher’s concern is whether the relationship between SITA and these departments is working or not. The research paradigm adopted is a constructivist approach and the ontological position adopted assumed multiple realities. The research method used in this study is the evaluation research method. Key to the research procedure was the fact that four senior officials were interviewed using audio recording, where in two were each chosen from SITA and ECTD. The researcher used document analysis and interviews as a means of collecting data. Separate open-ended questions for SITA and ECTD were structured in such a way that it would be easy to extract themes describing the details of a particular question. The researcher made use of thematic analysis. The theory drive-code development process was key in the research analysis. ECTD outsourced to SITA the following IT services, namely, provision or maintenance of a private telecommunication network (PTN) or a value-added network (VAN); transversal information systems and its data-processing or associated services; training in IT/IS; application software development; maintenance services for IT software or infrastructure; data-processing or associated services for specific IT applications or systems such as website development; and IT support. The interviewed officials from ECTD contend that they used the SCM Guide and SITA ACT when pursuing IT outsourcing for projects such as those listed above. One of the key projects outsourced to SITA is the IFMS, which is a project programme of the National Treasury Department working closely with provinces (e.g. ECTD), National Department of Public Service and Administration (NDPSA) and SITA. The IFMS project has been implemented following the SCM guidelines. The key SCM Guide components are demand, acquisition, logistics, and disposal management. The engagement model used by SITA to guide them on the process of engaging in an IT outsourcing relationship has, according to the officials interviewed, been a success. SITA uses a standard contract wherein other specific contracts receive minor adjustments. The impact of IT outsourcing has shown increases in customer satisfaction improvement, transformation of government procurement and provisioning practices, appointment of Consultants, interpretation of the Preferential Procurement Policy, promotion of the consistent application of Best Practices, information systems security environment, and improving service delivery.

Thesis (M.Sc. (Agricultural Management)) -- University of Limpopo, 2020 / The aim of this study was to investigate the role of Information Communication Technology tools in facilitating development within Community-Based Farming Projects (CBFPs) served by Mankweng Service Centre (MSC). The objectives of the study were to identify various ICT tools through which farmers get agricultural information, to determine the types of ICT-based agricultural information preferred by farmers in Mankweng, to examine the factors influencing use of ICTs by farmers in Mankweng and also to identify the challenges encountered by Mankweng farmers in their use of ICT. The study was cross-sectional in design and included 102 farmers from the Community-Based Farming Projects in Mankweng Service Centre as participants. Participants were selected using multi-stage sampling of combined cluster and systematic random sampling. Quantitative data was collected from participants using a structured questionnaire under the supervision of the researcher. Descriptive and inferential methods of analysis were employed. Data was summarised using frequency distribution of variables followed by measures of central tendency, measures of variance, and relationship of variables. Summary of findings was presented in the form of tables, figures and frequencies. Univariate regression model was used to analyse factors influencing use of ICT amongst farmers. The findings of the study show that majority (64%) of the farmers were women and (36%) of the farmers were men. Majority of the farmers (56%) were less than 50 years of age with 79% of the farmers having no tertiary education. The results of this study also revealed that the demographics of the participants were not the critical determinant factors in ICT usage (p>0.2) amongst farmers. The level of education farmers acquired was rather a very important predictor of the utilization of the ICT tools available to the farmers. The study revealed cell phones to be the most commonly used ICT device followed by Radio and TV. The study revealed that the affordability of ICT devices is the main challenge which ultimately limits access. Based on these findings, the study recommends that the Limpopo Department of Agriculture (LDoA) should make a provision of informal education sessions for farmers on the use of ICT devices, and ICT infrastructure and smart phones. In addition, the study recommends advocacy for more agricultural programmes through affordable platforms like TV and community radio stations media.

Thesis (M.A. (Communication Studies)) -- University of Limpopo, 2017 / The use of communication technologies has brought changes to our daily ways of doing things. Youth use technology for different purposes at different locations. As technology grows everyday with various advantages, its benefits come along with some disadvantages. Road accidents are one of the major problems that South Africa experiences. The focus of this study was to explore the danger of texting and driving and its potentials for road accidents. This research focused on the negative impact of technology, mainly technological distraction, while driving. Broadly, this research looks at the social and cultural impact of texting and mobility, with specific focus on distracted driving. This study is significant in the social analysis of technology use and distraction; this significance is made more important considering that there is very limited study of this social issue in South Africa. The always-available communication culture (such as texting while driving) should be viewed as a problematic phenomenal. For data collection, the researcher conducted a survey with adults and youth drivers to explore the perceptions and attitudes of drivers towards cell phone use, texting and driving. The researcher also conducted roadside observations of drivers to investigate the occurrence of distracted driving due to technology use, and interviews were conducted with Traffic Officers to share their professional experience on observing incidences of texting and driving. The study reveals that technology use, texting and driving is a common problem among young drivers, while adults tend to be more careful and engage less in this activity. Aspect of the findings of the study shows that 60% of drivers report that they have sent a text while driving. Moreover, the study explores ways of curbing cell phone use texting and driving on South African roads. There should be more research on distracted driving and technology use, so that more suggestions on how to curb technology use while driving can be offered

Through the evolution of digital media technology, social networks and more recently Web 3.0 (e.g. Cloud-based) technologies, culture and memory is being transformed, both in relation to how memories are represented, and how they may be engaged with or re-accessed. As digital technology alters ways in which knowledge is produced, stored, connected and shared, new terrains, tools and artefacts are formed; new cultural practices alter the ways in which we remember and the ways in which memory is processed, destabilising traditional “historically encoded social habits: religion, authority, morality, traditional values, or political ideology” (Diamantaki 2013). This doctoral project consists of two parts exploring questions of memory in contemporary time. The practice work submitted develops various imaginaries and investigates how to enable mnemonic practices so that works function as memory palaces where bodies and ‘collective' and ‘networked memories' (Hoskins, 2010) can be realised. The work, briefly summarised, includes communal activities in public spaces (a series of workshops and heritage day events, Rendezvous, centrally social activities organised between Fabrica and various charitable organisations in Brighton). It includes a series of installation works, as a transitional process of memory between body, object, an investigation of ubiquitous technology, are investigated – iremembr (2009-15); Rendezvous (2010-15); Untitled#21 (2012). And it leads to the development of an installation piece, 200.104.200.2 (2013-15), that seeks to offer or extend the possibilities of the act of remembering, of memory, as a post-Internet experience; a complex temporal, social, spatial and material, overlapping and merging human and silicon memory. In this, the written component of the combined and larger project, questions concerning memory and digital technology, and how to explore them, are taken up in theoretical terms, and the works I have produced returned to and explored in these contexts. A central project here has been to locate new forms of qualities of ‘digital' memory in a memory map or topology that builds on adapts, and develops other models. Aspects of zones of memory are explored centrally in each of the later thesis chapters each of which also takes up a particular aspect of my practice. The intention – and the contribution to the development of critical thinking around the digital – particularly critical thinking that comes through digital media art practice, is to question how digital technology intervenes in the process of memory; how the concept of digital memory is being thought about; leading me to investigate what does this new digital terrain do as it overlaps and re-writes to some extent the older ones? How does it change ‘how memory happens'.
