Internetanvändning – en digital möjlighet för att minska ensamhet och social isolering bland äldre : En strukturerad litteraturstudie / Internet use – a digital opportunity to reduce loneliness and social isolation among elderly : A structured literature review

Ahmed, Duha January 2023 (has links)
Introduktion: Ensamhet liksom social isolering bland äldre är ett folkhälsoproblem som återfinns i stora delar av världen. Antalet äldre personer förväntas öka exponentiellt inom de närmsta årtiondena. Därmed förväntas även prevalensen av ensamhetsdrabbade äldre att öka. Den sociala kontakten minskar med stigande ålder till följd av bland annat ökad sjukdomsbörda. Syfte: Syftet med denna studie var att undersöka hur internetanvändning i form av social gemenskap kan reducera ensamhet och social isolering bland äldre människor. Metod: Studien baserades på en strukturerad litteraturstudie. Totalt har 11 vetenskapliga artiklar inkluderats i litteraturundersökningen. Artiklarna analyserades utifrån en tematisk analys och utgick från en deduktiv ansats. Resultat: Den tematiska analysen resulterade i fyra huvudteman; förbättrad hälsostatus, distansvänlig kommunikation, digitala tillgångar och resurser, samt delaktighet – en del av förebyggandet. Ytterligare sju sub-teman identifierades; mindre ensamhet och social isolering, upprätthålla sociala relationer, digital kommunikation som komplement, lättanvända enheter och funktioner, brist på kunskap och erfarenhet, utbildning och stöd samt möjlighet till att påverka egen hälsa och välbefinnande. Slutsats: I stort sett finns det en del evidens som pekar åt att internetanvändning kan påverka äldres hälsostatus positivt och därmed minska ensamhet och social isolering. Dock förekommer barriärer, motgångar samt faktorer som bör tas i beaktande för att göra det möjligt för målgruppen att ta del av digitala möjligheter som finns tillgängliga och även underlätta användningen av dem. / Introduction: Loneliness and social isolation among elderly are public health problems found in large parts of the world. Elderly people are expected to increase exponentially within the next few decades. Thus, the prevalence of lonely elderly people is also expected to increase. Social contact decreases with increasing age as a result of, among other factors, an increased burden of illness. Aim: The purpose of this study was to investigate how internet use in the form of social connection can reduce loneliness and social isolation among older people. Method: The study was based on a structured literature review. A total of 11 scientific articles have been included in the literature review. The articles were investigated through a thematic analysis with a deductive approach. Results: The thematic analysis has resulted in four main themes; improved health status, distance-friendly communication, digital assets and resources, as well as participation – part of prevention. Additionally, seven sub-themes were identified; less loneliness and social isolation, maintaining social relationships, digital communication as a complement, easy-to-use devices and functions, lack of knowledge and experience, education and support, and the opportunity to influence own health and well-being. Conclusion: Altogether, there is some evidence that indicates that internet use can positively affect the health status of older people and thus reduce loneliness and social isolation. However, there are barriers, obstacles, and factors that should be taken into consideration to enable the target group to take advantage of digital opportunities that are available and also facilitate their use.

¿Cómo se comunica la investigación a través de la pantalla? Análisis del discurso multimodal en las comunicaciones en congresos digitales en el área de comunicación

López Navarrete, Alberto Jesús 19 February 2024 (has links)
[ES] La COVID-19 ha acelerado el proceso de adaptación al trabajo telemático donde el entorno académico también ha sufrido cambios. La comunidad investigadora ha normalizado la participación en congresos a través del ordenador. El objetivo de este estudio es analizar los elementos que intervienen en el discurso oral en las comunicaciones en congresos digitales académicos para identificar los patrones de comunicación más empleados por los investigadores. Desde inicios del siglo XXI, diversos autores han explorado este género discursivo al considerarlo el homólogo oral del artículo científico. Estos mismos autores demandan más atención a los géneros orales, al considerarlos infraestudiados en comparación con los géneros académicos escritos. Para el análisis se utiliza el Análisis del Discurso Multimodal (ADM). Esta metodología entiende que, solo considerando todos los elementos del discurso se puede tener una idea global de cómo es la comunicación. De este modo, considerar únicamente lo que se dice (el lenguaje) no permite descifrar todo el significado. Por ello, los autores del ADM proponen analizar elementos del aspecto visual, el lenguaje o los gestos del orador. Entre los resultados, destaca el protagonismo de las diapositivas en el discurso, el desarrollo de un patrón para la estructura del discurso y la poca relevancia de los gestos, que apenas son percibidos por la cámara. Estos datos permiten conocer los modelos de comunicación en los congresos digitales, así como atender a los elementos más urgentes que hay que tratar para mejorar la comunicación efectiva a través del ordenador y la cámara web. / [CA] La COVID-19 ha accelerat el procés d'adaptació al treball telemàtic on l'entorn acadèmic també ha patit canvis. La comunitat investigadora ha normalitzat la participació en congressos a través de l'ordinador. L'objectiu d'aquest estudi és analitzar els elements que intervenen en el discurs oral en les comunicacions en congressos digitals acadèmics per a identificar els patrons de comunicació més utilitzats pels investigadors. Des d'inicis del segle XXI, diversos autors han explorat aquest gènere discursiu al considerar-lo l'homòleg oral de l'article científic. Aquests mateixos autors demanden més atenció als gèneres orals, en considerar-los poc estudiats en comparació amb els gèneres acadèmics escrits. Per a l'anàlisi s'utilitza l'Anàlisi del Discurs Multimodal (ADM). Aquesta metodologia entén que, només considerant tots els elements del discurs es pot tindre una idea global de com és la comunicació. D'aquesta manera, considerar únicament el que es diu (el llenguatge) no permet desxifrar tot el significat. Per això, els autors de l'ADM proposen analitzar elements com l'aspecte visual, el llenguatge o els gestos de l'orador. Entre els resultats, destaca el protagonisme de les diapositives a les comunicacions, el desenvolupament d'un patró per a l'estructura del discurs i la poca rellevància dels gestos, que a penes són percebuts per la càmera. Aquestes dades permeten conèixer els models de comunicació en els congressos digitals, així com atendre els elements més urgents que cal tractar per a millorar la comunicació efectiva a través de l'ordinador i la càmera web. / [EN] The Covid-19 pandemic has accelerated the adaptation to remote work, leading to significant changes in the academic environment. The academic community has normalized participation in conferences through computer screens. The aim of this study is to analyze the elements involved in oral discourse during digital conference papers to identify the communication patterns most commonly used by researchers. Since the early 21st century, several authors have explored this discursive genre, considering it the oral counterpart of scientific articles. These authors advocate for more attention to oral genres, considering them understudied in comparison to written academic genres. This study employs Multimodal Discourse Analysis (MDA). This methodology understands that a comprehensive understanding of communication can only be achieved by considering all elements of discourse. Merely focusing on what is said (language) does not reveal the full meaning. Therefore, MDA advocates for the analysis of visual aspects, language, and gestures of the speaker. The results highlight the prominence of slides in discourse, the development of a pattern for discourse structure, and the limited relevance of gestures, which are barely perceived by the camera. These findings provide insights into communication models in digital conferences and draw attention to the most pressing elements that need to be addressed to enhance effective communication through computers and webcams. / López Navarrete, AJ.

Fritidshemmets digitala kommunikation med vårdnadshavare : En kvalitativ studie ur ett socialvetenskapligt och kommunikationsvetenskapligt perspektiv / Leisure-time centers' digital communication with guardians

Fridhamn, Matilda, Civic, Michaela January 2023 (has links)
Studien undersöker vårdnadshavares erfarenheter av ineffektiv och effektiv digital kommunikation mellan fritidshem och vårdnadshavare. Syftet är att få insikt i vårdnadshavarnas upplevelser av att ta emot och förstå digital kommunikation. Påverkansfaktorer som teknologi, tydlighet, återkoppling, anpassning, förväntningar och erfarenheter undersöks i syfte att analysera deras inverkan på kommunikationens effektivitet eller ineffektivitet. Resultaten tyder på att vårdnadshavarna generellt sett har goda möjligheter att ta emot och förstå digital kommunikation, trots vissa problem. Identifierade negativa kommunikativa faktorer inkluderar bristfälliga plattformar, otydlig och begränsad information samt brist på regelbunden och relevant kommunikation. Slutsatsen är att ökad kunskap och medvetenhet om vårdnadshavares upplevelser av digital kommunikation och dess påverkansfaktorer är önskvärt för att gynna både vårdnadshavare, deras barn och fritidshemmet som organisation. / The study examines legal guardians' experiences of ineffective and effective digital communication between leisure-time centers and guardians. The aim is to gain insight into guardians' experiences of receiving and understanding digital communication. Factors of influence such as technology, clarity, feedback, adaptation, expectations, and experiences are examined in order to analyze their impact on the effectiveness or ineffectiveness of communication. The results indicate that guardians generally have good opportunities to receive and understand digital communication, despite some challenges. Identified negative communicative factors include inadequate platforms, unclear and limited information, and a lack of regular and relevant communication. The conclusion is that increased knowledge and awareness of guardians' experiences of digital communication and its influencing factors are desirable to benefit both guardians, their children, and the leisure-time centers as an organization.

Ecopoiese e as formas comunicativas do habitar atópico / -

Torres, Julliana Cutolo 06 May 2014 (has links)
A digitalização do território e a sua transformação em fluxos informativos (DI FELICE et al, 2012) resultaram em um outro modo de ser sobre a Terra, de ser-no-mundo contemporâneo, mais particularmente no que o sociólogo Massimo Di Felice (2009) define com o conceito de \"habitar atópico\", desenvolvido a partir da pensamento de Heidegger. Para ele, mais do que residir, o habitar refere-se a um relacionar-se, a um comunicar, caracterizado pelas interações em rede dos diversos coletivos humanos e não-humanos, tecnológicos, territoriais. Assim, mais do que a reprodução digital do território, trata-se de um novo ambiente, um \"metaterritório\", metageográfico e informativo, portanto, dinâmico e manipulável, cujas dimensões são sempre reticulares e indelimitáveis (DI FELICE et al, 2012). É nesse panorama que se pretende esboçar os caminhos para a proposição do conceito de \"ecopoiese\", entendida como uma ecologia que, ao contrário do que o sentido etimológico possa induzir, é do âmbito do atópico e do indizível. Seu oikos não se localiza e seu logos não se explica. Essa ecologia é pós-humanista e assim sendo, o somente humano não a define e nenhuma perspectiva única a reivindica. Nessa ecologia, as interações entre humano, natureza e tecnologia comunicativa assumem um caráter complexo e produzem sempre agenciamentos hibridizantes, divergindo de quanto preconizado pelas interações somente técnicas atribuídas à Internet das Coisas / The digitalization of the territory and its transformation into information flows (DI FELICE et al, 2012) resulted in a further way of being on earth, of being-in the contemporary world, more particularly in what the sociologist Massimo Di Felice (2009) defines with the concept of \"atopic inhabit\", developed from the thought of Heidegger. For him, rather than reside, dwelling refers to a relate to, to a communicate with, characterized by networked interactions of the human and non-human, technological, territorial collectives. Thus, more than the digital reproduction of the territory, it is a new environment, a \"metaterritory, a \"metageographical\" and informative one, and therefore dynamic and manipulable, whose dimensions are always reticular and unlimited (DI FELICE et al, 2012). It is in this scenario that is intended to outline the ways to propose the concept of \"ecopoiese\", here understood as an ecology that, instead of what the etymological sense may suggest, is the scope of the atopic and unspeakable. Your oikos is not localized and its logos is not explained. This ecology is post-humanist and, therefore, what is only human cannot define it and no single perspective can claim it as theirs. In this ecology, the interactions between human, nature and communication technology play a complex character and always produce hybridized assemblages which are different from merely technical interactions attributed to the Internet of Things

The theoretical basis of this thesis articulates the concept of community of practice with references from Wenger, Lave, McDermott, Synder and Matta; collaboration, as proposed by Oliveira and Magalhães; reflexive and shared teacher development according to Pimenta, Vázquez, Gimeno, Sacristán, Tardiff, Masetto; and integration of DICT in education as discussed by Valente, Almeida and others. The researched contexts were Communities of Practice in Brazil, namely Grupo de Estudos Educar na Cultura Digital, Práxis, Grupo de Sábado, Portal do Professor and Nética; and, in Portugal, ArcaComum and Pigafetta. Besides these players, the research natural intervention environment was the municipal school Governador André Franco Montoro, located in the town of Campo Limpo Paulista, in the state of São Paulo. The methodological approach was action research. Data analysis and interpretation were built on the definition of 7 potentiality indicators depicted from the collected data. The analysis used the multidimensional statistic method of hierarchical ranking by similarity, through data compilation in CHIC software, which showed similarity or similitude in the data referring to shared teacher development and the resulting effects in the teacher s own practice as a consequence of participating in an Online Community of Practice. The results showed that the sharing of experience in a OCoP has enabled us to build up knowledge about the integration of DICT in educational context. The participants spent the better understand your role as an agent of change that organises and reflects on their pedagogical actions in the classroom / Esta pesquisa tem como objetivo analisar quais são os indicadores de potencial das COP online no Brasil e em Portugal que contribuíram para a formação compartilhada dos professores no desenvolvimento de competências pedagógicas com o uso das TDIC constituindo a COP online denominada COPFUCA, no âmbito do projeto UCA. O referencial teórico desta tese articula os conceitos de comunidades de prática com referências em Wenger, Lave, McDermott, Synder, Matta; colaboração Mandaji, Oliveira e Magalhães; formação compartilhada e reflexiva de professores baseado em Pimenta, Vázquez, Gimeno Sacristán, Tardiff, Masetto; integração do uso das TDIC no processo educacional, Valente, Almeida, dentre outros. Os contextos investigados foram as Comunidade de Prática no Brasil: Grupo de Estudos Educar na Cultura Digital, Práxis, Grupo de Sábado (GDS), Portal do Professor, Nética; e em Portugal ArcaComum e Pigafetta. Além disso, teve como ambiente natural de intervenção a escola municipal EMEF Governador André Franco Montoro localizada no município de Campo Limpo Paulista, São Paulo. A abordagem metodológica adotada foi a da pesquisa ação. A análise e interpretação dos dados nesta pesquisa foram construídas a partir da definição de 7 indicadores de potencial identificados nos extratos coletados. Na análise adotou-se o método estatístico multidimensional da classificação hierárquica de similaridade por meio da compilação dos dados no software CHIC que evidenciou a similaridade ou semelhança entre os dados referentes à formação compartilhada dos professores e os efeitos causados na própria prática pedagógica ao participar de uma COP online. Os resultados evidenciaram que o compartilhamento de experiência em uma COP online permitiu construir conhecimento sobre a integração das TDIC no contexto educacional. Os participantes passaram a compreender melhor o seu papel enquanto agente de mudanças que planifica e reflete sobre suas ações pedagógicas em sala de aula

No. of bitstreams: 1 imagem.pdf: 3526629 bytes, checksum: 2b8ae7994cf555fe9618160e1573cba8 (MD5) Previous issue date: 2006-06-05 / The images (painting, photograph, cinema, etc.) had always been constructed for specific ends and through the mediation between us (spectators) and the reality, it was possible to represent the world that surrounded us. With the arrival of the graphical computation and new digital formats, the image acquires new abilities. To argue the properties and trends of the digital image are extremely excellent aspects for the development of new systems, processes and theories in communication. When it is conceived and allied to the interface concept, this image can be transformed into image-interface, thus multiplying, its characteristics and potentialities. A good platform to think the digital medias as inhabitable medias and the parameters to argue the transformation of the image in image interface is the digital video disc, because it possess technical characteristics witch allows the mapping of information and the storage of great amount of data. The objective of this research is to argue and apply the image-interface concepts, elaborated mainly by Peter Weibel, Lev Manovich and Mark Hansen, in the DVDs and the new formats of the digital communication like the Internet and electronic panels. The interfaces analysis of commercial and experimental DVDs and DVD Roms will allow to understand the current limitations in the interfaces´exploration and argue if it is possible to extend its resources and to use these concepts in the scope of a market culture, which a media quickly is substituted by another one before they deplete its possibilities / As imagens (pintura, fotografia, cinema, etc.) sempre foram construídas para fins específicos e através da mediação entre nós (espectadores) e a realidade, foi possível representar o mundo que nos cercava. Com a chegada da computação gráfica e de novos formatos digitais, a imagem adquire novas competências. Discutir as propriedades e tendências da imagem digital são aspectos extremamente relevantes para o desenvolvimento de novos sistemas, processos e teorias comunicacionais. Ao ser concebida e aliada ao conceito de interface, essa imagem pode ser transformada em imagem interface, multiplicando assim, suas características e potencialidades. Uma boa plataforma para pensar as mídias digitais e os parâmetros para discutir a transformação da imagem em imagem interface é o disco de vídeo digital, pois possui características técnicas que permitem o mapeamento de informações e o armazenamento de grande quantidade de dados. O objetivo desta pesquisa é discutir e aplicar os conceitos de imagem-interface, elaborados principalmente por Peter Weibel, Lev Manovich e Mark Hansen, no ambiente dos DVDs e dos novos formatos da comunicação digital, como a Internet e os painéis eletrônicos. A análise de interfaces de DVDs e DVD Roms comerciais e experimentais permitirá entender as limitações atuais na exploração da interface e interrogar se é possível ampliar seus recursos e se utilizar desse conceitos no âmbito de uma cultura de mercado, dentro da qual uma mídia é rapidamente substituída por outra antes que esgotem suas possibilidades

Animação computadorizada: a imagem em movimento expandida nos meios de comunicação digitais

Andrade, Daniel Grizante de 15 May 2007 (has links)
Made available in DSpace on 2016-04-26T18:16:09Z (GMT). No. of bitstreams: 1 Daniel Grizante.pdf: 2918521 bytes, checksum: 71ad07526df988433b11ffbd68ff288d (MD5) Previous issue date: 2007-05-15 / The objective of this thesis is the research and mapping of the changes undergone by animation with the increased use of computer technology in the creative and productive processes and the advent of new digital communication media. Due to the range of the term animation, an historical-evolutive line known as authorial animation was priorized. For this, contemporary works of animation with innovative use of computer technology were analyzed, including works from artists such as Mark Napier, Marius Watz, Zachary Lieberman, Ckoe, Hans Hoogerbrugge and Motomichi Nakamura, as well as animation series for the Internet such as Stainboy, Ninjai and Cinema Bulbo, and movies such as Waking Life, Ryan, Ghost in the Shell Innocence, among others. The analysis is based on Deleuze s theory of moving images (from which animation is not distinguished), as production of thought that result in a subtle relationship between language, media, technology, poetic intentions, esthetics and ethics, revealing true forms of reflection. From this analysis, three major themes, all extremely important for the comprehension of this kind of computer animation, emerged: the movement created through code, the synthetic moving image and the new media in animation and its influence on the creative process. It was established that Animation a language historically connected with technological media - occupies today an im-portant place in current audiovisual production since its approach of movement is fully compati-ble with contemporary concepts of constructing moving images / A presente dissertação tem como objetivo a pesquisa e mapeamento das mudanças sofri-das pela animação em seus processos criativos e produtivos com o crescente uso da computação e com o surgimento de novos meios de comunicação digitais. Devido à abrangência do termo a-nimação , decidiu-se priorizar uma linha histórico-evolutiva do que conhecemos como cinema de animação. Para tanto, foram analisadas obras contemporâneas de animação que utilizam a tecno-logia computacional de forma inovadora para a linguagem, a exemplo de trabalhos de artistas como Mark Napier, Marius Watz, Zachary Lieberman, Ckoe, Hans Hoogerbrugge e Motomichi, além das séries de animaçãos para internet Stainboy, Ninjai e Cinema Bulbo e dos filmes Waking life, Ryan, Ghost in the shell, entre outros. As análises deram-se a partir da constatação deleuzia-na de que a imagem em movimento, da qual a animação não se distingue, é produção de pensa-mento e, portanto, resulta de uma sutil relação entre linguagem, meios, tecnologia, intenções poé-ticas, estéticas e formações éticas, revelando verdadeiras formas de reflexão. A partir destas aná-lises, surgiram três grandes temas de suma importância para a compreensão desta animação pro-duzida mediante a utilização da computação: o movimento criado a partir de códigos de progra-mação, a imagem em movimento sintética e os novos meios de recepção da animação e sua influ-ência no processo criativo. Constatou-se que a animação, linguagem historicamente ligada aos meios tecnológicos, ocupa hoje lugar de destaque na atual produção audiovisual, já que suas a-bordagens do movimento são plenamente compatíveis com os conceitos contemporâneos de construção da imagem em movimento
