Exploring the role of information and communication technology on employees' work and family domains / Johannes Willem de Wet

De Wet, Johannes Willem January 2015 (has links)
Technology has become part of society’s everyday functions, changing rapidly and providing widespread mobility. In South Africa alone, the amount of internet users grew from 8,5 million to 24,9 million in only three years (2011-2014). Currently 90% of these users access this facility from their mobile devices. This statistic illustrates the trend that South Africans are moving towards a continually connected lifestyle, a situation in which information and communication technology (ICT) seems to have become omnipresent. Due the rapid growth of ICT technology and its adoption into people’s lives (both personally and professionally) the influence of such a phenomenon needed to be investigated to understand its impact on individuals and society. Thus, the objective of the present research was to explore the role ICT plays in employees’ work and family domain. The research followed a qualitative research approach and made use of snowball sampling. The sample of participants (N=25) were mostly employees from a professional organisation. Semi-structured interviews were conducted to collect data and the interviews were recorded, transcribed and processed through thematic analyses. The analyses revealed the following four main themes with sub-themes flowing from it: 1) the usage of ICT; 2) the role of ICT usage; 3) the challenges relating to ICT usage; and 4) managing work-life interaction by using ICT. Theme 2 lend itself to be sub-divided into four minor subthemes namely: 1) the positive role of ICT usage; 2) the negative role of ICT usage; 3) the role ICT plays in relationships; and 4) the increased expectations brought about by ICT usage. The current research was not without certain limitations, which should be noted. The researcher only investigated the employees themselves and did not extend the unit of analysis to include the household of employees (esp. the partner or spouse). In addition, the majority of the participants were Afrikaans-speaking males, which is not a true reflection of the multicultural society of South Africa promoting gender equality in the work place. Based on the findings of the present research, various recommendations could be made. Future research could firstly enlarge the sample to be more representative of South Africa’s multicultural and diverse society, and secondly, to include the partner or spouse of employees. Organisations should also consider the implementation of various policies on ICT usage. These directives could include the following: a policy to ensure across the board ICT implementation; an after-work hours policy to ensure as little as possible infringement on employees work-life interaction; and a hierarchical policy ensuring the correct communication channels are followed. Lastly, future research could also do multiple comparative studies on the differences between the degree of ICT adoption, or the amount of ICT devices employees utilise and the impact this has on their work-life interaction. Such research can also investigate how the decrease in face-to-face communication impacts social interaction in both the work and nonwork domains and thereby affects employees’ work-life interaction. / MCom (Industrial Psychology), North-West University, Potchefstroom Campus, 2015

Comparação de métodos de estimação em pequenas áreas para proporções: o caso da TIC Educação / A comparison of methods in small areas estimation for proportions: the ICT Education case

Coelho, Isabela Bertolini 28 April 2016 (has links)
A sociedade atual é também conhecida como Sociedade da Informação, pois o acesso às informações e ao conhecimento está disponível de maneira rápida através das Tecnologias de Informação e Comunicação (TIC), como computador, Internet e telefone celular. Assim, tem sido necessário elaborar novas maneiras de pensar e conviver com essas tecnologias. Para o desenvolvimento socioeconômico das nações é importante formar uma sociedade crítica, reflexo do processo educacional adotado; dessa maneira, é preciso se apropriar das TIC para obter práticas de ensino mais criativas e flexíveis. Para que essa integração gere resultados satisfatórios é preciso a união de diversos fatores como a infraestrutura disponível na escola, o domínio dos professores sobre a utilização nas atividades de ensino-aprendizagem, a integração no projeto político-pedagógico, a implementação de políticas públicas na área educacional pelo governo etc. Dessa forma, o levantamento de dados estatísticos sobre a adoção das TIC nos processos educacionais se faz necessário. Pesquisas amostrais são muito utilizadas com o intuito de conhecer determinada característica sobre uma população. O tamanho das amostras costuma ser planejado para a obtenção de dados para grandes áreas, no entanto, vem crescendo o desejo de se obter informações em níveis mais desagregados, onde o tamanho da amostra é pequeno para a produção de estimativas com precisão aceitável, sem aumentar o tamanho amostral. Em vista disso, a metodologia de estimação em pequenas áreas tem sido desenvolvida de forma a produzir estimativas com precisão adequada para as características de interesse, considerando a distribuição de probabilidade trazida no desenho amostral ou a utilização de modelos que emprestam informações para áreas semelhantes. O objetivo desta dissertação é a obtenção dessas estimativas para a proporção de escolas em que os professores usam a Internet em atividades de ensino-aprendizagem com os alunos para cada Unidade Federativa do Brasil, utilizando dados reais provenientes da pesquisa TIC Educação, produzida pelo CGI.br, e do Censo Escolar, produzido pelo INEP. Obtemos as estimativas por diferentes abordagens, tanto direto da amostra quanto através da construção de modelos de regressão logística, e as comparamos através da estimativa do erro quadrático médio e da proporção de acertos, através da matriz de confusão por validação leave-one-out. Para a consolidação dos resultados obtidos nos dados reais, fazemos um estudo de simulação de dados. O modelo de efeitos aleatórios é considerado como o que apresentou os melhores resultados. / The current society is also known as the Information Society because access to information and knowledge is available through Information and Communication Technologies (ICT) such as computer, Internet and mobile phone. Thus, new ways of thinking and living with these technologies have become necessary. For the socio-economic development of nations it is important to create a critical society, reection of adopted educational process; In that way, appropriating ICT should be necessary to obtain more creative and exible teaching practices. To obtain satisfactory performance it needs the union of several factors such as the infrastructure available in schools, the teacher\'s knowledge about how to adopt ICT on practical activities, the ICT integration on the political pedagogical project, the implementation of public policies on the educational sector etc. In this manner, collect statistical data about ICT adoption on teaching practices is necessary. Sample surveys are widely used in order to understand certain characteristics of a population. The sample sizes is often designed to obtain results for large areas, nevertheless, the desire to obtain these results for more disaggregated areas, where the sample size is small to produce reliable estimates, are increasing without increasing the sample size. Small area estimation methodology has been developed to produce reliable estimates about some desired characteristics considering the probability distribution introduced on the sample design or considering models to lend information to resembling domains. Our purpose is to obtain estimates to the proportion of schools wherein teachers use the Internet to teaching-learning activities with their students for each Federative Unit of Brazil using real data from ICT in Education Survey, conducted by CGI.br, and Scholar Census, conducted by INEP. We obtain these estimates from dierent aproaches both by direct estimator and by logistic regression models and we compare them under the mean squared error and the proportion of success using confusion matrix by leave-one-out cross-validation. To consolidate these results we do a simulation study. The logistic random eects model is considered the best approach.

A programação total do ambiente: infraestruturas planetárias da comunicação / The total environmental programming: planetary infrastructures of communication

Girard, Lucas Tavares de Menezes 18 May 2017 (has links)
Esta dissertação considera o espaço produzido pelas redes de infraestruturas da informação e comunicação (TIC) em seus aspectos geográficos, materiais e sua incidência no espaço urbano. Por meio da visão de autores como Milton Santos, Marshall McLuhan, Paul Virilio e Mark Wigley, constituiu-se um arcabouço teórico para a articulação de uma narrativa do processo histórico de formação destas redes, bem como para identificar alguns de seus efeitos sobre o ambiente urbano. Considerandose a atual invisibilidade destas infraestruturas nas práticas urbanísticas atual, neste trabalho são apresentadas definições de \"infraestrutura de informação e comunicação\" e um roteiro de imagens de cartografias e representações das diferentes tecnologias de comunicação em distintos períodos histórico. O objetivo é apresentar aspectos concernentes à geografia da informação e sua influência sobre a sociedade. À guisa de conclusão, apresentamos três apontamentos sobre as implicações decorrentes do incremento da incidência das TICs no espaço urbano e no meio social. / This dissertation is organized around information and communication infrastructure networks (ICT) space, regarding its geographic, material aspects as well as its incidence over urban space. Through the lens of authors such as Milton Santos, Marshall McLuhan, Paul Virilio and Mark Wigley, we have articulated a brief narrative of the historical processes behind these networks and also have identified some of its effects over urban environments. Taking into account the absence of these infrastructures in the current urbanistic practices, in this work we present conceptual definitions of \" information and communication infrastructure\" and also display a sequence of images, cartographies and representation of different communication technologies is distinct historical periods. Our goal is to display the geography of information and its influence over society. As a conclusion, we introduce some critical notes on the implications related to the increase of ICTs in the urban environment.

Contribuições da pedagogia de projetos e do uso das Tecnologias de Informação e Comunicação (TICs) para o ensino de Geografia - um estudo de caso. / Contributions of the Pedagogical Project and the use of the Information and Communication Technologies (ICTs) for the Teaching of Geography - The study of a case.

Carolino, Jussara de Abreu 18 December 2007 (has links)
Objetivamos demonstrar nesta pesquisa as contribuições da Pedagogia de Projetos associada ao uso das Tecnologias de Informação e Comunicação (TICs) no ensino de Geografia, no sentido de criar novos ambientes de trabalho e estimular o aluno, com base nos princípios da autonomia e da colaboração, a buscar aprendizagem contextualizada e com significado. A modalidade de pesquisa adotada foi a empírica; o procedimento técnico utilizado foi o estudo de caso - realizado na Escola Odete Maria de Freitas, Embu/SP, com alunos do Ensino Fundamental, precisamente duas salas de 8ª série. Foram elaboradas e desenvolvidas duas propostas didáticas para o ensino de Geografia, que associam a Pedagogia de Projetos, especificamente o projeto \"Mi lugar\" e o \"Ih! Tá acabando\", ao uso das TICs. Os resultados mostram que é possível proporcionar ensino pautado na criação/apropriação de novos ambientes de trabalho, possibilitando ao aluno aprendizagem contextualizada e com significado. O desenvolvimento das propostas didáticas destacadas foi bastante positivo - percebido por meio do empenho, da dedicação e do comprometimento dos envolvidos no processo. O trabalho permitiu a criação de conexões com o cotidiano e a participação do educando, de forma dinâmica e interativa. Foram construídos conceitos não só pertinentes à Geografia mas com a perspectiva de integração dos saberes, de aprender a conhecer, a fazer, a encontrar significado na própria atuação. Os alunos passaram de meros receptores de informações para produtores de seu próprio conhecimento; tornaram-se responsáveis pelo seu aprendizado. A ação do professor foi fundamental nesse processo, por meio de pedagogias diferenciadas, mediação e prática reflexiva. Portanto, são muitas as questões que permeiam o estudo acerca das contribuições da Pedagogia de Projetos e do uso das TICs no ensino/aprendizagem. Questões que perpassam pelo âmbito das concepções do professor e do aluno sobre aprendizagem, pela idealização; desenvolvimento e aplicação de práticas escolares inovadoras; pelo aporte da formação de professores; como também pela infraestrutura tecnológica necessária para a implementação das TICs na escola. Esses temas precisam ser pensados em consonância com os novos paradigmas educacionais, inseridos no mundo atual, com suas formas específicas de organização social. É preciso considerar ainda as necessidades de aprendizagem do aluno, seu contexto social e educativo, para a implementação de uma proposta pedagógica eficaz. / In this research we intend to demonstrate the contributions of Project Pedagogy associated with the use of Information and Communication Technologies (ICTs) to the teaching of Geography, in order to create new work environments and stimulate the student, based on the principles of autonomy and collaboration, to learn in a contextualized and significant way. An empirical model of research was adopted and the technical procedure used was the case study - which took place at the school Escola Odete Maria de Freitas, Embu/SP, with primary school students in two 8th grade classrooms. Two didactic proposals were worked out and developed for the teaching of Geography that associates the use of ICTs with Project Pedagogy, specifically the projects \"Mi lugar\" and \"Ih! Tá acabando\". The results show that it is possible to offer education based on the creation/appropriation of a new work environment, making it possible for the student to have a contextualized and meaningful learning experience. The development of the didactic proposal was very positive - as evidenced by the engagement, dedication and commitment of the people involved in this process. The work allowed the creation of a connection to day-to-day life and the participation of the student in a dynamic and interactive way. Concepts were elaborated that are not only related to Geography, but in a perspective of integration of areas of knowledge, of learning to know, to do, and to find meaning in one\'s own actions. The students turned from mere receptors of information into producers of their knowledge; they became responsible for their learning experience. The teacher\'s role was fundamental in this process, by using different teaching methods and through a process of mediation and reflection. This research raises many questions about the contributions of Project Pedagogy and the use of ICTs in teaching and learning questions about the teacher\'s and student\'s conceptions about learning; by idealization, development and the application of new school practices; through the contribution of teacher training; as well as the technological infrastructure needed to implement ICTs at school. These issues need to be thought about bearing in mind new educational paradigms, inserted in the world of today, with its specific social organization. We must consider the student\'s educational needs and his social and educational context if we are to develop and implement an effective pedagogical proposal.

Informatização e unificação dos programas de proteção radiológica: monitoramento das radiações ionizantes e sua otimização / Web-based system to unify the radiological protection programs: ionizing radiation monitoring and optimization

Levy, Denise Sahyun 25 August 2015 (has links)
Um programa de monitoramento para fins de proteção radiológica deve mostrar como ele auxilia na obtenção e demonstração de um grau de proteção adequado e comprovar que as condições de trabalho continuam satisfatórias com o transcorrer do tempo. Para o controle operacional das exposições à radiação ionizante em qualquer local de trabalho, a Comissão Internacional de Proteção Radiológica (CIPR) recomenda um programa de proteção radiológica operacional, proporcional ao grau de risco, para garantir o gerenciamento efetivo das medidas necessárias para se satisfazer o principio da otimização. O presente trabalho de pesquisa tem como premissa o potencial das Tecnologias da Informação e Comunicação (TIC) como ferramenta para a comunicação e disseminação do conhecimento em Proteção Radiológica. O trabalho inclui a informatização da filosofia e técnica do monitoramento e sua otimização, unificando e inter-relacionando informações advindas de diversas publicações nacionais e internacionais, oferecendo às instalações radiativas brasileiras um veículo completo para informação e pesquisa, que permite dimensionar os esforços de otimização tornando-os eficazes e justificados. O sistema oferece ainda tópicos de discussões no intuito de ampliar o repertório dos profissionais do campo da proteção radiológica, suscitando novas reflexões a favor da segurança. Trata-se dos temas desenvolvidos nesta tese, a saber: a necessidade de um monitoramento auditor e discussões mais aprofundadas sobre as exposições potenciais. As reflexões propostas na presente tese vêm ao encontro das novas exigências internacionais, propondo ações passíveis de serem incorporadas na prática laboral. Dentro dos princípios da proteção radiológica, a implementação de um programa de monitoramento auditor permite avaliar se os critérios e ações previamente estabelecidas pelo Serviço de Proteção Radiológica são ou não atendidos, se foram implementados com eficácia e se permanecem adequados. Os fatos resultantes dos procedimentos de auditoria auxiliam a detectar deficiências no processo, possibilitando conclusões e recomendações diante de possíveis fatores desencadeadores de exposições indevidas. Por meio de exames sistemáticos das atividades realizadas em cada tipo de monitoramento, a auditoria infere segurança ao processo, respaldando o trabalhador na realização do monitoramento relacionado com a tarefa e respaldando a instalação, que empreende ações responsáveis a favor da segurança. Em relação às exposições potenciais, somente duas publicações da CIPR são expressivas e desenvolvem o assunto. Entretanto, ainda que forneçam a fundamentação teórica, são incompletas em seus exemplos. Há uma grande falta de conhecimento das probabilidades de falhas, o que atualmente constitui um vasto campo de pesquisa da proteção radiológica. A presente tese propõe, a partir de árvores de falhas, caminhos que auxiliam a quantificar probabilisticamente a ocorrência das exposições potenciais e a probabilidade de se atingir um determinado valor da dose. Acreditamos que o potencial das TIC contribuirá largamente para a disseminação da informação para as instalações radiativas, estimulando o desenvolvimento neste país de grandes extensões territoriais, onde permanece um desafio oferecer o acesso à informação ao maior número de pessoas possível, minimizando custos e maximizando resultados. / A monitoring program for the purposes of radiological protection should demonstrate an adequate protection degree and prove that working conditions remain appropriate as time goes by. For operational control of exposures to ionizing radiation in any workplace, the International Comission on Radiation Protection (ICRP) recommends establishing a program of operational radiation protection, proportional to the risk, to ensure the effective management of all necessary measures to satisfy the principle of optimization. This research work focus on the potential value of Information and Communication Technologies (ICTs) to enhance communication and education on Radiological Protection throughout Brazil. The work includes the informatization of the monitoring policy and techniques, interrelating information currently scattered in several documents, providing Brazilian radioactive facilities a complete repository for research, consultation and information, which allows to size optimization efforts by technology, enabling them to be effective and justified. The content of monitoring programs involves not only the collection and interrelationship of existing information in the publications, but also new approaches from some recommendations, presenting some initiatives towards safety. In this sense, the two contents researched and expanded are: the need for an auditor monitoring and discussions on potential exposures. The recommendations proposed in this thesis meet the new international requirements stablished by the International Agency of Nuclear Energy (IAEA) and propose appropriate actions to be incorporated into labor practice. Respecting the scope of the principles of radiological protection, an auditing program permits to evaluate whether criteria and actions previously established by Radiological Protection Service are effectively implemented and remain appropriate as time goes by. The results of auditing procedures help to detect deficiencies in the process, enabling conclusions and recommendations, avoiding possible triggers of undue exposures. Through systematic examinations of activities in each type of monitoring, auditing attempt to ensure the process, supporting the employee in performing task-related monitoring and support the facility that choose responsible actions towards safety. Furthermore, regarding potential exposures, only two publications of ICRP develop expressively the issue. Even though these publications provide the fundamental theory, they are incomplete in their examples. There is still lack of knowledge of failure probabilities, which currently constitutes a broad research field in radiological protection. This research work proposes the development of fault trees, suggesting paths to quantify probabilistically the occurrence of potential exposures, as well as probabilities to reach a certain level of dose. We believe that the potential of ICT shall contribute greatly to provide information where it is needed, stimulating development in this large country where it is a strong challenge to ensure access to information to as many people as possible, minimizing costs and optimizing results.

Future technology in public transportation : a qualitative study based on public transportation authorities attitudes

Hammarsten, Anna, Ohlsson, Emma January 2019 (has links)
The issue that this study addresses is the public transportations difficulty to adapt and keep up with the continuously digitizing society. To address this problem, the purpose of this study will be to investigate what could be a contribution to the further improvements within public transportation systems. The study is established alongside with the recently started “Welcome onboard” project, where the purpose is to develop and extend the public transportation as we know it today. The aim is to through five different functional areas urge the utility, where crowdsourcing will play a central role. We are distinguishing three public transport authorities attitudes towards the different functions of the project. We will investigate the attitudes towards the Welcome  onboardprojects functions and if they could be a contribution to the RKM-companies future development. Furthermore, this thesis will also investigate how the RKM-companies would grade the different advantages of different functional areas, and in a extend what would bevital for an future implementation. The empirical data collection consist of interviews of informants with a deep understanding ofthe development of the public transportations. First we interviewed two key persons of the Welcome onboard project, to get a deep understanding of the project. Later on we interviewed key persons at Värmlandstrafiken and Västtrafik, that are two different regional public transportation authorities. To strengthen our results we also chose to interview Samtrafiken, which task are to develop collaborations and offer services within information and ticket solutions for the public transport industry. This is made in order to benefit both traffic the RKM and the travelers.  All the interviews were transcribed and analyzed, later the empirical data collection could be compared through different cases. These cases were categorized by information about the company that the interviewees where representing and the answers regarding the attitudes towards the “Welcome onboard”-project and its functions. The result from the thesis will give an understanding of Västtrafik, Värmlandstrafiken and Samtrafikens perspective of the functions and attitudes towards the further development of public transportation.

No. of bitstreams: 1 Julia Dreher Pacheco da Silva_.pdf: 1726907 bytes, checksum: f1524d6d728bbf1d0a21116b3568ad5a (MD5) Previous issue date: 2018-03-22 / Nenhuma / Esta pesquisa, tem como objetivo investigar de que forma os usuários das tecnologias da informação e comunicação se relacionam com os diferentes níveis de vigilância propiciada pelos ambientes corporativos. Para delimitação dos sujeitos foram escolhidas as pessoas que nasceram entre 1985 e 1995, conhecidos como geração Y. Em sua fundamentação teórica, foram trabalhados quatro conceitos: gerações, tecnologias da informação e comunicação, e vigilância. A pesquisa empírica foi realizada em diferentes movimentos, partindo de acercamento através de pesquisa exploratória, que forneceu elementos para que fosse possível planear os movimentos de ação/intervenção no campo de estudo. Após a realização do aporte teórico, foi realizado entrevistas de profundidade com usuários da geração Y, que se enquadrassem em preceitos de vigilância cibernética, com o intuito alcançar os objetivos propostos pelo trabalho. Os movimentos de interpretação dos fenômenos foram realizados de maneira a complementar uns aos outros, problematizados e pensados de acordo com as especificidades da realidade investigada e dos sujeitos inseridos nas dinâmicas e processos de vigilância. Os resultados apontam que os sujeitos da geração Y, escolhidos para estudos apresentam comportamentos homogêneos perante ambientes corporativos vigiados ciberneticamente, enquadrando-se em comportamentos exigidos por causa da constante vigilância. podendo-se fazer-se de comparação com o conceito de vigilância do autor Jeramy Benthan (2000): o dispositivo panóptico. / The purpose of this research is to investigate how information and communication technology users are related to the different levels of surveillance provided by corporate environments. For the delimitation of the subjects, were chosen people who were born between 1985 and 1995, known as generation Y. In its theoretical foundation, four concepts were worked out: generations, information and communication technologies, and surveillance. The empirical research was carried out in different movements, starting from an approach through exploratory research, which provided elements so that it was possible to plan the action / intervention movements in the field of study. After the theoretical, interviews were carried out with users of generation Y, who were in accordance with cybernetic surveillance precepts, in order to reach the objectives proposed by the work. The movements of interpretation of the phenomena were carried out in a way to complement each other, problematized and thought according to the specificities of the investigated reality and of the subjects inserted in the dynamics and processes of surveillance. The results indicate that the subjects of the generation Y, chosen for studies, presented homogeneous behaviors in the cybernetically monitored corporate environment, being in accordance with the behaviors demanded by the constant vigilance, which one can be compared with the theory of surveillance: the Panópticon , by Bentham (2000).
