Communication without borders : A quantitative study on how mobility and a cosmopolitan self-identity affect Swedish expatriates communication patterns with friends. / Kommunikation utan gränser : En kvantitativ studie om hur mobilitet och en kosmopolitisk självbild påverkar utlandssvenskars kommunikationsmönster med vänner.

Agin, Sol January 2016 (has links)
The purpose of this study is to find out how Swedish voluntary migrants communicate with friends in three different groups: friends that resides in the same country as the respondent currently lives in, friends in Sweden, friends in other countries around the globe and whether or not individual mobility, demographic factors or a sense of global citizenship affect the chosen mean of communication. The reason behind the study is to introduce a previously unstudied area into the field of geographically based media studies and hopefully contribute to a deeper understanding of the role played by different means of communication in shaping the dynamics of global friendship. The theoretical approach in this study will be from three different outlooks, migration, polymedia (including the second-level digital divide) and cosmopolitanism. The study is based on data from the Institute for Society, Opinion and Media (SOM) and their survey questionnaire sent out to Swedish expatriates during fall 2014 / winter 2015, also known as Utlands-SOM. The total number of respondents are 2268. The study starts with basic frequencies to find out which media that are the most prominent, then binary logistic regressions have been made. The total number of dependent variables are 21 and these have then been analysed from seven independent variables; age, gender, education, travel patterns, years spent abroad, number of countries lived in and whether or not the respondent consider himself/herself being a cosmopolitan. This generates a total of seven tables (one for each media) with three models in each (contact with friends in current country of residency, contact with friends in Sweden and contact with friends in other parts of the world). Amongst Swedish expatriates, e-mail and Facebook are the two most popular media for keeping in touch with friends, regardless of the friends location. The most significant demographic variable is age. Usage of video call, text message, chat, Facebook and other social media tend to decrease with age. Every year spent abroad decreases the communication with friends in Sweden, but increases the communication in the current country of residency. The number of countries lived in have a positive effect on communication with friends in other parts of the world. Cosmopolitan self-identity is found to be most significant when communicating with friends in other parts of the world, and it also affects e-mail the most. Level of education, which in previous studies have been found closely linked to a cosmopolitan identity, is found to have no significant correlation. Arguably, this is explained by the other means of communications negative relationship with the variable. / Syftet med denna studie är att ta reda på hur svenskar som frivilligt emigrerat utomlands kommunicerar med vänner inom tre olika grupper: vänner som bor i samma land som respondenten för tillfället lever i, vänner i Sverige samt vänner bosatta i övriga länder världen över. Detta sätts i perspektiv med huruvida den individuella mobiliteten, demografiska faktorer eller en känsla av ett världsmedborgarskap påverkar det valda kommunikationsmedlet. Denna studie ämnar att introducera ett tidigare förbisett forskningsområde inom geografiskt baserade mediestudier och därigenom förhoppningsvis bidra till forskningsfältet genom en fördjupad förståelse om kommunikationsmediers roll för vänskapsdynamik på global skala. Det teoretiska ramverk som utgör studiens grund är tre stycken skilda delar, migration, polymedia (inklusive en andra gradens digital klyfta) och kosmopolitism. Denna studie bygger på data från Institutet för Samhälle, Opinion och Media (SOM), och deras undersökning ställd till utlandssvenskar (Utlands-SOM) från hösten 2014 / vintern 2015. Totalt antal respondenter är 2268. Först görs en enkel frekvenstabeller för att undersöka vilket/vilka de primära medierna är i varje grupp, därefter har binära logistiska regressioner körts. Det totala antalet beroende variabler som behandlas är 21. Dessa sätts i perspektiv med ålder, kön, utbildning, resemönster, antal år utomlands, antal boendeländer och om respondenten anser sig vara världsmedborgare eller ej. Detta genererar totalt sju tabeller (en för varje media), med tre modeller i varje (kontakt med vänner i nuvarande boendeland, kontakt med vänner i Sverige och kontakt med vänner i övriga världen). Utlandssvenskarnas favoritmedium för att hålla kontakten med vänner, oavsett var vännerna befinner sig, visade sig vara e-post och Facebook. Den mest signifikanta demografiska variabeln visade sig vara ålder. Användandet av videosamtal, SMS, chatt, Facebook och andra sociala medier visade sig minska med högre ålder. För varje år respondenterna spenderar utomlands minskar oddsen för kommunikationen med Sverige, men ökar i det nuvarande boendelandet. Antalet länder som respondenterna har bott i har en positiv inverkan på kommunikationen med vänner i övriga världen. Den kosmopolitiska identiteten är mest signifikant när det kommer till att kommunicera med vänner i övriga världen och den påverkar även e-post som medium allra mest positivt. Utbildningsnivå, vilket sedan tidigare studier funnits vara tätt länkat med en kosmopolitisk identitet, visade sig inte vara signifikant i denna undersökning. Detta kan förklaras genom de andra kommunikationsmediernas negativa förhållande med variabeln.

Otevřenost českých tradičních medií vůči neuživatelům Internetu / The issue of openness of the Czech traditional media towards Internet non-users

Macek, Oskar January 2015 (has links)
This paper deals theoretically and empirically with the issue of traditional media openness towards Internet non-users and its perception among non-users themselves. The theoretical part of the work outlines the problem of inequality in the information society and how specific content of messages in selected traditional media can contribute to these inegualities. The second part examines through a pilot content analysis the nature of the media content in the traditional Czech mass media with regard to the possibility of interaction and participation with the media and the usage of links to the digital content. On this basis, semi-structured interviews examine perception and reflection of such phenomena on a selected group of elderly non-users. The conclusion of this work consists of the introduction of the scheme of factors influencing the extent of perceived discrimination among non-users of the Internet in relation to traditional mass media.

Digitální gramotnost sociálně vyloučených adolescentů / Digital literacy of socially excluded adolescents

DOBIÁŠ, Václav January 2019 (has links)
With the advent of digital technology into our lives, the fact that the socially weakest stratum of society is lagging behind in digital literacy is becoming increasingly apparent. This problem is referred to as the second form of the digital divide. Since it has not yet been sufficiently examined, we carried out qualitative research using the grounded theory method, aimed at identifying the causes leading to this second form of the digital divide and defining the development model for this inequality. The collection of data was conducted by means of students solving tasks focused on digital literacy. In the course of this process, the computer screen was recorded and the entire investigator-student communication was captured on an audio track. Subsequently, semi-structured interviews were conducted with the students and their teachers. On the basis of analysis of the data, we created a theory of learning to handle an unknown software program. The process of learning exposes the student to various problems. The strategy used by each student to address these is chosen by the person depending on their previous knowledge of and experience with similar situations, particularly with similar software. The effectiveness of the applied strategy is overseen by the student's metacognitive control mechanisms. On the basis of the results obtained, the student's learning may (or may not) occur that improves the person's knowledge and skills, thus influencing how he/she addresses similar problems in the future. We see the benefits of our theory in describing a process of independent learning in the specific world of digital technologies. This can make the theory highly beneficial for teaching informatics. On the basis of this theory we described differences between socially excluded students and the majority in learning how to handle unknown programs. On the basis of our research, we believe in the long term that the difference in speed of lifelong learning in the field of handling digital technologies is the root cause of the emergence of the digital divide. During data analysis we identified a total of eight factors influencing the speed of lifelong learning in this sector; half of these also directly affect the level of digital literacy through the ability to solve problems. The resulting theory describes the lifelong process of the emergence of the digital divide. We see the main gain of our work in the identification of the process of emergence of the digital divide.

Distance and online learning in Botswana : challenges and mitigation strategies.

Selelo, Edward 09 March 2012 (has links)
The advent of the internet has resulted in the development from mail, radio and telephonic modes of delivery to electronic mode of delivery in distance education. It has been predicted that the impact of the internet on distance and online education will result in benefits such as wider reach of learners who might be disadvantaged by geographical locations and distance, greater flexibility and increased convenience for distance and online learners. However, the envisaged benefits seem to be elusive as a result of a range of impediments, including issues related to the digital divide. In this case study, focused on on-line students at a college of distance and open education in Botswana, students perceptions’ of both the benefits of and the impediments to their study are described, together with their perceptions of support strategies. Findings indicate the need for support strategies consistent with the nature of online learning in the 21st century. In particular, the findings of this study suggest that Web 2.0 technologies have the potential to enhance learner support, and that there is a need for careful exploration of the ways in which such technologies can be exploited and applied in support of on-line learners.

"Det är svårt med appar och hela köret..." : En kvalitativ studie om pensionärers användning av sociala medier

Danielsson, Zacharias, Fromell, Hampus January 2019 (has links)
Syfte och frågeställningar: Syftet med föreliggande studie är att undersöka hur svenska pensionärer ser på sin användning av sociala medier och på vilka sätt som sociala medier upplevs påverka både skapandet och upprätthållandet av relationer med den nära omgivningen. Studien ämnar även undersöka hur de uppfattar eventuella konsekvenser av sitt lägre deltagande i sociala medier, i relation till digitalt utanförskap.   Hur beskriver pensionärer 67 år och äldre sitt användande av sociala medier?   Hur upplever pensionärer att sociala medier har förändrat deras sätt att skapa och upprätthålla relationer med sin omgivning?   Om deltagandet i sociala medier är lågt, hur upplever pensionärer att det kan medföra konsekvenser för att upprätthålla relationer med sin omgivning?   På vilka sätt kan användandet av sociala medier bidra till att nyttja eller öka individers sociala kapital? Metod och material: Studien har en kvalitativ ansats och det empiriska materialet består av fokusgruppsdiskussioner med sammanlagt 17 seniorer (67-86 år).   Huvudresultat: Majoriteten av deltagarna uppgav att de använder sociala medier på daglig basis och att deras kommunikation med omgivningen har påverkats av sociala medier. Vidare beskriver respondenterna att ett lågt deltagande inte nödvändigtvis hänvisas till ett digitalt utanförskap – och att sociala medier är ett verktyg för att nyttja sitt sociala kapital.

Iniciativas de inclusão digital: um estudo sobre o programa de telecentros comunitários da cidade de São Paulo / Iniciaves of digital inclusion: a study about the São Paulo Community Telecentre Program

Cruz, Irandy Marcos da 11 December 2007 (has links)
A assimilação das TICs pelas diferentes sociedades desponta como a mais nova fronteira de debate sobre as diferenças entre pobres e ricos e sobre a capacidade dos indivíduos se inserirem de forma autônoma, como sujeitos ativos da construção de sua história. As tecnologias quando não difundidas ao conjunto amplo da sociedade, acabam por aprofundar um já existente problema de divisão social. Caberiam, então, ações de políticas públicas para minimizar os efeitos negativos acarretados pelos processos de transformação tecnológica, promovendo ações de inclusão digital. Assim, neste contexto, o presente trabalho se propõe a pesquisa a política de inclusão digital promovida pela prefeitura de São Paulo através do Programa de Telecentros Comunitários. Tendo como perspectiva a visão dos profissionais que trabalham no atendimento e orientação aos usuários de cada unidade. / The assimilation of ICTs in different societies is viewed as the newest frontier of debate on the differences between rich and poor and on the ability of individuals were entering so autonomous, as assets subject of the construction of its history. The technologies when not pushed to the broad set of society, ultimately deepen an existing problem of social divide. In this case is obligation of the govern shares of public policies to minimize the negative effects forward by the process of technological transformation by promoting actions of digital inclusion. Thus, in this context, this work is proposed to search the policy of digital inclusion promoted by the mayor of Sao Paulo through the Program of Community Telecenters. With the prospect the vision of professionals working in the care and guidance to users of each unit.

Empowered Youth: The Co-Creation of Youth as Technological Citizens and Consumers Within Community-Based Technology Programs

Pabst, Johanna January 2014 (has links)
Thesis advisor: Stephen Pfohl / The purpose of this study is to investigate the new media ecologies of urban, low-income youth and youth of color, and how they develop literacies and competencies around technology in the particular spaces of Community Technology Centers (CTCs), while placing them within their broader technological experiences and raced, classed, and gendered identities. This study builds on the concept of youth as experiencing a "new media ecology" in which youth engagement with technology is understood as a phenomenon which connects all spheres of experience. Through this work, I refine the understanding of how marginalized young people engage with technology in order to expand our understanding of digital inequality and its effects, as well as how digital inequality and inclusion interact with young people's identities and social worlds more broadly. Young people, marginalized by their raced, classes, and gendered identities, are both accused of being wasteful in their technology engagement, and are welcomed into these non-traditional learning spaces in order to cultivate their uses of technology into more meaningful and productive outcomes. There is a growing proliferation of informal and creative digital learning programs, and corresponding research and interrogation of the activities within these spaces. However, we lack a full and holistic understanding of who these young people are as technological citizens and consumers, an understanding that is necessary to inform effective interventions around digital inequality. Through qualitative research within two Boston-area Community Technology Centers, including participant observation and interviews, this study presents an analysis of how young people as agentic individuals interact with the contexts they enter into to produce new forms of agency and disempowerment. Rather than focusing on one area of the digital learning environment or youth technological experience, as other researchers have done, I delineate a more complete and dialogic view of less-advantaged young people and their technological engagement. My findings build on the need for supportive informal technology learning environments for marginalized youth, both in terms of providing stable environments with rich resources for technological exploration and skill-building, as well as providing learning environments which valorize and encourage youth agency and identity work. It is also necessary to recognize and allow for differences among youth in these spaces, who vary not only in terms of race, class, and gender, but also skills, abilities, interests, and motivations. I also call attention to the ways in which structural inequalities enter into these informal learning environments, resulting in their reproduction. / Thesis (PhD) — Boston College, 2014. / Submitted to: Boston College.

No. of bitstreams: 1 Lúcia Helena da Silva Alves.pdf: 1645318 bytes, checksum: be28418f5daba6e97b5246470ed4eb15 (MD5) Previous issue date: 2018-03-09 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / Currently, we experience several extremely violent scenarios that reach the most vulnerable portion of the population, who lives in the outskirts of the big cities. Thisresearch has as its objective to deepen the theoretical investigation on trauma in a situation of extreme violence, which implies reviewing the technical devices from the field of knowledge of psychoanalysis. It is from the field of knowledge that the analyst uses the clinical devices, such as listening, floating attention, free association, transference, interpretation, among others, in order to comprehend the psychological dynamics of the subjects who have experienced trauma, those who feel vulnerable and helpless. Within this context, we ask ourselves: what is trauma? Which psychic processes are part of it? How does the recurrence of traumatic affection manifest itself in clinic? What are the psychoanalytical devices that we can use? The perception is that we are sailing in troubled waters within the clinic, where the analysis of these patients shows us that theory and practice need to be reviewed. It is in the context of the clinic that a space is opened for the individual to talk about his or her trauma–it is understood that the subject, by suffering from violence, sees him or herself invaded in all psychic spaces for the excess of intolerable pulsional energy directed to ‘Me’, whose exaggeration derives from lived experiences by the individual with the external world. The therapeutic space is the place of the reunion between the subjects, the one that takes care, and the one who is taken care of. This clinical model is not the one from the excluded, the less favoured classes, the oppressed, the ones from anywhere –but a space of reception of different subjects. In order to illustrate this research, we resorted to the method of case fragment, which is considered one of the most ancient methods used in human and social science, not only in clinical practice but also in research. The first fragment refers to Antígona, mother, human rights militant who had her son killed by a State’s agent; the second, Iolaos, boy, sexually abused by his neighbour Prócusto. It is at the light of Ferenczi’s theory and other contemporary authors that we will analyse this psychic functioning manner founded in the divide mechanism. The clinical services seek to give a new meaning to the perception of trauma and its subjective repercussions unleashed in the subject’s life, generating pulsional motions that are repeated, relived and that manifest themselves in the form of psychic suffering, with representations that need to be symbolized / Na atualidade,estamos vivenciando vários cenários de violências extremas que atingem a população mais vulnerável, que vive nas periferias das grandes cidades. Esta pesquisa tem como objetivo aprofundar a investigação teórica sobre o trauma em situação de violência extrema, o que implica em rever os dispositivos técnicos a partir do campo dosaber da psicanálise. É a partir do campo dosaber que o analista faz uso dos dispositivos clínicos, taiscomo:a escuta, a atenção flutuante, a associação livre, a transferência,a interpretação, entre outros,para compreender a dinâmica psíquica dos sujeitos que vivenciam o trauma, os quais sesentem vulneráveis e desamparados. Dentro desse contexto, nos perguntamos: oque é o trauma? Quais processos psíquicos ocompõem? Como a repetição dos afetostraumáticosse manifesta na clínica? Quais os dispositivos psicanalíticos que poderemos utilizar? A percepção é de estarmos navegando em mares revoltos da clínica, onde as análises desses pacientes nos mostram que a teoria e a prática precisam ser repensadas. É no contexto da clínica que se abre o espaço para o indivíduo falar do trauma sofrido –entende-seque o sujeito,ao sofrer uma violência, vê-se invadido em todos os espaços psíquicos pelo excesso de energia pulsional intolerável voltado para o eu, cujo exagero é retirado das experiências vividas pelo indivíduo com o mundo externo. O espaço terapêutico é o lugar do reencontro entre os sujeitos, aquele que cuida, e quem é cuidado. Esse modelo clínico não é o dos excluídos, das classes menos favorecidas, dosoprimidos, de qualquer lugar -mas um espaço de acolhimento de diferentes sujeitos. Para ilustrar esta pesquisa recorremos ao método de fragmento de caso, o qual é considerado um dos métodos mais antigos utilizados nas ciências humanas e sociais, tanto na prática clínica quanto na pesquisa. O primeiro fragmento se refere aAntígona, mãe, militante de direitos humanos que teve oseufilho morto por um agente do Estado; osegundo, Iolaos, garoto, abusado sexualmente pelo vizinho Prócusto. É a luz da teoria ferencziana e de outros autores contemporâneos que analisaremos esse modo de funcionamento psíquico fundado no mecanismo da clivagem.Os atendimentos clínicos visam ressignificara vivência do trauma e suas repercussões subjetivas desencadeadas na vida do sujeito, gerando moções pulsionais que são repetidas e revividas e se manifestam na forma de sofrimento psíquico, cujasrepresentações precisam ser simbolizadas

Critérios para avaliação da alfabetização computacional / Criteria for assessing computer literacy

Wang, Marco Alberto 23 October 2015 (has links)
A tecnologia da informação e comunicação (TIC) tem se tornado cada vez mais comum no cotidiano da sociedade atual. Diversas são as facilidades disponibilizadas para os indivíduos habilitados no uso da TIC. Entretanto, estar habilitado em TIC não corresponde apenas a aspectos de conforto; a falta dessa habilitação restringe oportunidades importantes. Destaca-se a relevância deste conhecimento no ambiente acadêmico, no qual os alunos são constantemente chamados à execução de atividades apoiadas por computadores e aplicativos. Para ingressar no mercado de trabalho, nas mais diversas áreas de atuação, tem-se exigido o prévio preparo relacionado aos conhecimentos e habilidades sobre a TIC. Felizmente, os dispositivos de TIC têm se tornado cada vez mais acessíveis à população em geral, e os aplicativos também têm oferecido usabilidade cada vez mais intuitiva. Ainda assim, constata-se que a autoaprendizagem sobre TIC é restrita a alguns aspectos específicos, e ainda considerada insuficiente para um preparo minimamente adequado. Como agravante, as ações de incorporação da TIC no ensino público brasileiro ainda são malsucedidas. Esta dissertação tem como objetivo principal a definição de critérios para avaliação da Alfabetização Computacional (AC), correspondente à identificação do conjunto relevante de conhecimentos e habilidades de TIC, aplicada a alunos do ensino médio. Para atender a esse objetivo, os principais aspectos da AC foram extraídos da literatura por meio de uma revisão sistemática, e submetidos à análise de especialistas pela aplicação da Técnica Delphi. Os aspectos de TIC identificados como mais relevantes pelos especialistas para AC são: ética, ferramentas de busca, privacidade, segurança e vírus. Em complemento, este estudo também visa descrever como as instituições de ensino médio e as empresas avaliam a relevância dos conhecimentos e habilidades de AC. Os dados coletados possibilitaram uma análise comparativa de pontos de vista distintos dos docentes, pesquisadores e empresas sobre o tema. Concluiu-se que a conectividade corresponde ao elemento central da AC na atualidade, com base no conjunto de aspectos classificados como mais relevantes pela metodologia de pesquisa aplicada. / Information and communication technology (ICT) has become increasingly common in the daily life of today\'s society. Many conveniences are made available to all individuals by using ICT. However, knowledge of ICT does not refer only to aspects of comfort; the lack of this competence restricts important opportunities. Noteworthy is the great importance of this knowledge in the academic environment, in which students are constantly required to perform activities supported by computers and applications. In order to enter the job market, in several areas, prior preparation related to knowledge and skills on ICT is required. Fortunately, ICT devices have become increasingly accessible to the population in general, and applications have also been offering increasingly intuitive usability. Still, it appears that ICT self-learning is restricted to some specific aspects, and considered insufficient for a minimally adequate preparation. To make matters worse, the learning of ICT in Brazilian public schools is still insufficient. This dissertation aims at defining some criteria for assessing Computer Literacy (CL), corresponding to an identification of the relevant body of knowledge regarding ICT skills, to be applied to high school students. In order to meet this goal, the main aspects of CL were extracted from literature by a systematic review, and submitted to expert analysis by Delphi Technique. The aspects of ICT identified as the most important ones by experts at CL are: ethics, search engines, privacy, security and viruses. In addition, this study also aims at describing how high school institutions and companies evaluate the relevance of CL knowledge and skills. The collected data has allowed a comparative analysis of different points of view of teachers, researchers and companies on the subject. We have concluded that connectivity represents the central element of CL nowadays, based on the set of issues classified as the most relevant by the research methodology.
