A Doença de Alzheimer (DA) é a doença mais prevalente entre as demências, retratada por déficits progressivos da memória, funções cognitivas e funcionalidade. Apesar das evidências dos benefícios do exercício físico nas funções cognitivas e no declínio funcional, há poucos estudos com idosos com DA, que incluem efeitos de programas multimodais de exercícios físicos comparados com idosos sem DA. Os objetivos foram comparar os efeitos do programa multimodal de exercícios físicos na capacidade funcional, memória e atenção em idosos sem e com DA. Foram randomizados vinte idosos sem DA para grupo controle (NDA-C) ou grupo treinamento físico (NDA-T) e 18 idosos com DA no grupo controle (DA-C) ou treinamento físico (DA-T). Todos realizaram avaliação do nível sócio econômico, nível de atividade física (Questionário Internacional de Atividade física), e avaliação neuropsicológica (Miniexame do Estado Mental, Teste Breve de Desempenho Cognitivo, Escore Clínico de Demência e Escala de Depressão Geriátrica). A avaliação funcional incluiu testes de resistência muscular de membros inferiores (MMII) e superiores (MMSS) (Teste de Sentar e levantar e Teste de Flexão do cotovelo), capacidade aeróbia (Teste de Marcha estacionária), flexibilidade de MMII e MMSS (Teste de Sentar e alcançar e Teste de Alcançar atrás) e agilidade/equilíbrio dinâmico (Teste de Levantar e ir). A avaliação da amplitude de movimento de ombro e tornozelo foi realizada através do Flexímetro. Os grupos DA-T e NDA-T participaram do programa durante 6 meses, 2 vezes/semana com duração de 75 minutos cada sessão. A análise estatística para verificar diferenças entre os quatro grupos no período inicial foi realizada por Análise de variância (ANOVA) de 1 fator. E para verificar diferenças entre os grupos antes e depois de 6 meses foi realizada ANOVA de 2 fatores. No caso de significância foi realizado uma análise de pos-hoc com Tukey. Admitiu-se, em todas as análises, o nível de significância de 5% (P 0,05). O programa aumentou significativamente (P < 0,05) o nível de atividade física no lazer, a força muscular de MMSS, capacidade aeróbia, flexibilidade de MMII e amplitude de extensão de tornozelo e ombro nos grupos NDA-T e DA- T. Os grupos NDA-T e DA-T melhoraram a capacidade de agilidade e equilibro dinâmico em relação ao grupo DA-C. O programa proporcionou melhora significativa (P < 0,05) na força muscular de MMII do grupo NDA-T e, na flexibilidade de MMSS e amplitude de flexão de tornozelo e ombro no grupo DA-T. Após a intervenção houve melhora significativa (P < 0,05) da memória dos grupos NDA-T e DA-T, e da atenção no grupo NDA-T. Conclui-se que o programa foi efetivo para aumentar o nível de atividade física no lazer, capacidade aeróbia, força muscular de MMSS, flexibilidade de MMII e amplitude de extensão de tornozelo e ombro, bem como a memória dos idosos, independente da presença da DA. O declínio da agilidade/equilibro dinâmico e da atenção do DA-T foi atenuado em relação ao DA-C. Estes benefícios contribuem para um melhor desempenho nas atividades da vida diária melhorando a qualidade de vida dos idosos com e sem DA / The Alzheimer Disease (AD) is the most prevalent disease between all the dementia, and it is portrayed by progressive deficits of memory and cognition. Besides all the evidences of the benefits of the physical exercises to the cognitive function, there are a few studies that include the effects of the multimodal programs on the physical function and cognitive functions, comparing older adults with and without AD. The goals were compare the multimodal program effects in functional capacity, memory and attention on older adults with and without AD. Twenty older adults without AD were randomized on Control Group (NAD-C) or Physical Training Group (NAD-T) and eighteen elderly with AD were randomized on control group (AD-C) or physical training group (AD-T). All patients realized socioeconomic evaluation, physical activities level (International Physical Activities Questionary), and neuropsychological evaluation (Mental State Miniexam, Syndrom Kurztest, Clinical Dementia Rating and Geriatric Depression Screening Scale). On the period of 6 months, the NAD-T and AD-T groups, participated on the multimodal program, the exercise routine was 2 times a week and the duration of 75 minutes. A measuring functional fitness of older adults were applied, the tests evaluated the Inferior and Superior liths muscular Resistance/Strenght (30-second Chair Stand and Arm Curl), Aerobic Capacity (2-minute Step), the lower and upper body flexibility (Chair Sit-and-Reach, and Back Scratch tests) and agility/dynamic balance (8-foot Up and Go). The shoulder and ankle amplitude evaluation tests were realized using a Fleximeter. The statistical analysis to verify if there was any difference between the four groups (NAD-C, NAD-T, AD-C and AD-T) on the initial period were realized using the Variance Analysis (ANOVA) 1way. The statistical analysis to verify the difference between the groups before and after the six months period was realized using the ANOVA 2way. In the case of significance, were used the Tukey Pos-Hoc analysis. In all analysis the level of significance was 5% (P 0.05). The multimodal exercise program was effective to increase the leisure time physical activity level of older adults with or without AD. The program, also contributed to increase the physical conditioning, getting a significant improvement (P<0.05) on the upper body muscular strength, aerobic capacity, upper and lower body flexibility, and, on the Shoulder and Ankle extension amplitude, in the NAD-T and AD-T groups. The NAD-T and AD-T groups improved agility/dynamic balance in relation to the AD-C group. Concerning the cognition, after exercise program, the groups NAD-T and AD-T showed an improvement on the memory (P<0.05). However, the attention only improved in the NAD-T group (P<0.05). Independent of multimodal physical exercise program was improve the leisure time physical activity level, aerobic capacity, upper body muscular strength, lower body flexibility shoulder and ankle extension, and memory in the older adults. The program attenuated the decline in agility/dynamic balance, and attention in DA-T group. These benefits contribute to a better performance in daily living activities which contributes to improve the quality of life of the older adults with and without AD

Pesquisa do Estado da Bahia - FAPEB / This paper presents a study on the ways noted by the Indirect Anaphoras ( Marcuschi , 2005) in verbal- visual texts that enrich the possibilities for ( re) construction of the senses through elements of verbal and visual language . In light of this, this study will be from the theoretical perspective of Linguistics Textual, a social cognitive - interactional approach. The corpus consists of a selection of the genre strips, which has as main character a little boy named Calvin, name entitles these narratives created by American cartoonist Bill Watterson, exposed in the "Current" the New School Magazine and on the official site on the internet. About the indirect anaphoric relations, it can be said that there is a direct relationship between the antecedent (anchor) and the anaphoric term, which is introducing a new referent and the anaphoric relationship depends on an interpretation based on a calculation of inferential nature. Thus, it is considered that only the relations of lexical-semantic nature are not sufficient to explain the anaphoric relations and argues that these settings also depend on contextual and conceptual factors that allow the organized distribution of discourse objects, fulfilling a role important in textual progression. The results reinforce the relations established through the indirect anaphora and their anchors are not linked to the notion of correference and even it isn?t having this direct relationship, anchored in the textual universe, extrapolating the co-text and mobilizing a wide universe of cognitive strategies inherent in sociocultural interaction of the individual. The introduction of a new element in the text, even it not directly related to an antecedent, enables thematic continuity ensuring the textual progression. / RESUMO Neste trabalho, apresenta-se um estudo sobre os modos de referir por meio das An?foras Indiretas (MARCUSCHI, 2005) em textos verbo-visuais, que enriquecem as possibilidades de (re)constru??o dos sentidos atrav?s de elementos da linguagem verbal e da linguagem visual.

El presente estudio tiene por finalidad analizar cómo se aplica el uso de la imagen en la enseñanza multimodal en el libro Amigos dos- textos para el séptimo y octavo año de educación primaria o básica en Suecia. Para ello, se propone una revisión teórica sobre el uso de la imagen en la enseñanza de idiomas, y un análisis de imágenes y textos del libro mencionado como caso de estudio. Nuestro análisis muestra que la relación enunciado e imagen contribuye a la construcción del conocimiento multimodal. / The purpose of this study is to investigate the use of the image in multimodal teaching/learning based on the didactik book Amigos dos-textos, applied for teaching the Spanish language in Sweden, in the seventh and eighth year of primary school. To this end, a theoretical review is proposed on the use of the multimodal image for language teaching, and a case study is performed based on analysis of random images and text from the book. The analysis shows that the statement-image relationship represents a contribution towards the construction of multimodal knowledge.

Cette thèse porte sur la définition d'un schéma de recalage automatique en microscopie corrélative 2D et 3D, en particulier pour des images de microscopie optique et électronique (CLEM). Au cours des dernières années, la CLEM est devenue un outil d'investigation important et puissant dans le domaine de la bio-imagerie. En utilisant la CLEM, des informations complémentaires peuvent être collectées à partir d'un échantillon biologique. La superposition des différentes images microscopiques est généralement réalisée à l'aide de techniques impliquant une assistance manuelle à plusieurs étapes, ce qui est exigeant et prend beaucoup de temps pour les biologistes. Pour faciliter et diffuser le procédé de CLEM, notre travail de thèse est axé sur la création de méthodes de recalage automatique qui soient fiables, faciles à utiliser et qui ne nécessitent pas d'ajustement de paramètres ou de connaissances complexes. Le recalage CLEM doit faire face à de nombreux problèmes dus aux différences entre les images de microscopie électronique et optique et leur mode d'acquisition, tant en termes de résolution du pixel, de taille des images, de contenu, de champ de vision et d'apparence. Nous avons conçu des méthodes basées sur l'intensité des images pour aligner les images CLEM en 2D et 3D. Elles comprennent plusieurs étapes : représentation commune des images LM et EM à l'aide de la transformation LoG, pré-alignement exploitant des mesures de similarité à partir d'histogrammes avec une recherche exhaustive, et un recalage fin basé sur l'information mutuelle. De plus, nous avons défini une méthode de sélection robuste de modèles de mouvement, et un méthode de détection multi-échelle de spots, que nous avons exploitées dans le recalage CLEM 2D. Notre schéma de recalage automatisé pour la CLEM a été testé avec succès sur plusieurs ensembles de données CLEM réelles 2D et 3D. Les résultats ont été validés par des biologistes, offrant une excellente perspective sur l'utilité de nos développements. / This thesis is concerned with the definition of an automated registration framework for 2D and 3D correlative microscopy images, in particular for correlative light and electron microscopy (CLEM) images. In recent years, CLEM has become an important and powerful tool in the bioimaging field. By using CLEM, complementary information can be collected from a biological sample. An overlay of the different microscopy images is commonly achieved using techniques involving manual assistance at several steps, which is demanding and time consuming for biologists. To facilitate and disseminate the CLEM process for biologists, the thesis work is focused on creating automatic registration methods that are reliable, easy to use and do not require parameter tuning or complex knowledge. CLEM registration has to deal with many issues due to the differences between electron microscopy and light microscopy images and their acquisition, both in terms of pixel resolution, image size, content, field of view and appearance. We have designed intensity-based methods to align CLEM images in 2D and 3D. They involved a common representation of the LM and EM images using the LoG transform, a pre-alignment step exploiting histogram-based similarities within an exhaustive search, and a fine mutual information-based registration. In addition, we have defined a robust motion model selection method, and a multiscale spot detection method which were exploited in the 2D CLEM registration. Our automated CLEM registration framework was successfully tested on several real 2D and 3D CLEM datasets and the results were validated by biologists, offering an excellent perspective in the usefulness of our methods.

Visionsbilder över byggprojekt har under de senaste decennierna blivit en vanlig typ av platsmarknadsföring. Visionsbilder kallas även för renderingar och är ett slags digitala collage som försöker övertyga publiken om platsens förmåga att fungera. Till skillnad från fotografier är renderingar sammansatta av visuella element som aktivt valts ut av producenten. Visionsmaterial innefattar en maktdimension då materialet ligger till grund för politiska beslut gällande kommunalt finansierade projekt. Det finns i dagsläget inga studier på visionsbilder ur ett kommunikationsperspektiv i en svensk kontext. Genom en multimodal kritisk diskursanalys undersöker studien vilka värden och löften som synliggörs samt vilka ideologiska funktioner dessa producerar och reproducerar. Analysmaterialet består av visionsbilder med tillhörande text från tre svenska kommuner; Lund, Västerås och Kiruna. Resultatet påvisar en genomgående nyliberal ideologi där både platser, människor och praktiker kommodifieras. De ideologiska funktionerna synliggörs genom teman som; en aktiv livsstil, globalisering, gemenskap via konsumtion, estetiska val och utopiska fantasier. / Images representing a vision of urban redevelopment projects have during the last decades been more frequently used in place marketing. These rendered images are digital collages used to persuade the audience how the place is supposed to work. In rendered images all visual elements are, unlike photographs, composed by the producer. These types of images carry a power relation due to being a part of political decision financed by municipalities. There’s up to this point no research regarding this subject in a Swedish context. This study examines, through a multimodal discourse analysis, which values and promises are made visible and which ideological functions these images and texts produce and reproduce. The analysis covers urban visions regarding three Swedish municipalities; Lund, Västerås, Kiruna. The result depicts a strong commodification and a neoliberal ideology seen through themes like; active lifestyle, globalisation, community via consumption, esthetics and utopian fantasies.

Syftet med studien är att genom kritisk granskning få en fördjupad förståelse av fristående gymnasieskolors multimodala kommunikation på sina hemsidor gentemot grundskoleelever och deras vårdnadshavare. Avsikten är att jämföra de friskolor i Stockholmsområdet som hade högst respektive lägst meritvärde för antagning höstterminen 2019. För att undersöka detta används multimodal analys av tio fristående gymnasieskolors hemsidor. Resultatet presenteras utifrån olika kategorier med en bakgrund i sociosemiotisk teori. I resultatet framkommer att skolorna i gruppen med högst antagningsgräns ofta använder liknande semiotiska resurser vilka skiljer sig från de skolor med lägst antagningsgräns som inom sin grupp använder sig av semiotiska resurser som liknar varandras. De olika skolorna riktar sin kommunikation till olika grupper av elever och vårdnadshavare. Alla skolor använder sina egna semiotiska resurser för att skapa mening. Kombination av de semiotiska resurserna på en skolas hemsida skapar en viss förståelse hos betraktaren. / The purpose of this study is to achieve a greater understanding of multimodal communication towards prospective students and their guardians on webpages of independent upper secondary schools in Sweden. The intention is to compare independent schools in the Stockholm area which had the highest as opposed to the lowest limit of admission in the autumn of 2019. To investigate this, multimodal analysis of the websites of ten independent upper secondary schools is used. The results are presented in different categories based on social semiotic theory. Furthermore, the results show that the schools in the group with the highest admission limit often use similar semiotic resources and that they differ from the schools with the lowest admission limit. This group on the other hand, use semiotic resources that are similar to one another. The different schools direct their communication towards different groups of students and guardians. Schools use several individual semiotic resources which create understanding in combination with each other.

Lors du vieillissement sain, et malgré une augmentation de la fréquence d’apparition du manque du mot, les personnes âgées manifestent une préservation des performances de dénomination orale d’objets (DO), suggérant la mise en place de stratégies efficaces de récupération et de sélection de l’information lexicale. Dans ce travail de thèse, nous avons utilisé une approche méthodologique multimodale afin d’évaluer la nature de ces stratégies. Nous nous sommes plus spécifiquement intéressés aux mécanismes de réorganisation cérébrale ainsi qu’aux activités sociales comme facteur de réserve cognitive. Ce travail de thèse se décompose en cinq études et aborde une perspective homogène (effet de l’âge) et hétérogène (effet des performances) du vieillissement. Nos résultats mettent en évidence l’existence de différents mécanismes de compensation associés au vieillissement sain. Tout d’abord, nous observons que les personnes âgées sont plus lentes que les jeunes adultes lors de la DO, mais obtiennent un taux de précision similaire. D’après la perspective homogène, le maintien des performances de DO s’expliquerait par le recrutement d’une stratégie de nature sémantique. Au niveau cérébral, nous observons une augmentation de l’asymétrie intra-hémisphérique gauche des régions temporo-pariétales chez les personnes âgées, ainsi qu’un transfert de la connectivité normalement observée du gyrus frontal inférieur (GFI) gauche avec le gyrus temporal latéral au gyrus temporal médial gauche. D’après la perspective hétérogène, le maintien des performances de DO s’expliquerait par l’utilisation d’une stratégie de nature exécutive, reflétée par une réduction de l’asymétrie inter-hémisphérique frontale chez les personnes âgées dont les temps de réponse de DO sont courts. Par ailleurs, nous proposons que l’encodage lexico-phonologique module également le taux de précision de DO, via la connectivité effective entre le GFI gauche et le gyrus temporal supérieur gauche. Enfin, nous observons une relation significative entre la fréquence de participation aux activités sociales, notamment collectives, et les performances de DO. Cette relation est partiellement médiée au niveau cérébral par l’activité du gyrus frontal supérieur médian gauche, via un mécanisme de réserve neurale. Sur la base de nos résultats, nous proposons un modèle neurocognitif des stratégies de récupération et de sélection de l’information lexicale, utilisant une approche multimodale et plurifactorielle du vieillissement sain. / Despite increased difficulties to find words in the daily life, older adults show preserved object naming performances when compared to younger ones. This suggests a supplementary recruitment of compensatory strategies in order to retrieve and select words. In this research work, we have used a multimodal methodological approach to evaluate the nature of these strategies, by using an object naming task. Specifically, we have evaluated these strategies in terms of mechanisms of cerebral reorganization. We were also interested to know how these strategies are modulated by the frequency of social activities, considered as a factor of cognitive reserve. This thesis work is composed of five studies performed under a homogeneous (effect of age) and a heterogeneous (effect of performance) perspective. Based on results, we suggest that aging is associated with multiple compensatory mechanisms to maintain a correct level of performance. Specifically, according to the homogeneous perspective, we consider that preserved object naming performances in older adults might be explained by the use of a semantic strategy. Indeed, in older compared to younger adults and at a cerebral level, we observed increased left hemispheric asymmetry with significant recruitment of the temporo-parietal regions. In addition, the inferior frontal gyrus (IFG) that is connected to the lateral temporal cortex in younger adults, seems to “switch” its connectivity toward the left medial temporal gyrus in older adults. In addition, according to the heterogeneous perspective, preserved object naming performances in older adults can be also explained by the use of an executive strategy, reflected by reduced inter-hemispheric asymmetry of frontal regions, specifically in more performant older adults (with shorter response latencies). Furthermore, we suggest that lexico-phonological processes mediate naming accuracy as reflected by the increased connectivity from the left IFG to the left superior temporal gyrus. A final result that we report in this work indicates that the frequency of participation to group social activities correlates to naming performance in older adults. This relation is partially mediated by the left superior medial frontal gyrus and is assimilated to a neural reserve mechanism. Overall, based on our findings, we propose a neurocognitive model of lexical retrieval and selection strategies in normal aging, based on a multimodal dataset and a multifactorial approach.

The purpose of this study is to analyze and compare the connection between pictures and text in three textbooks, in english, in the expectation to reach a didactic perspective that can facilitate in working with texts with students, in fourth grade.  How well do pictures and text correspond with each other in three textbooks that have been chosen for the fourth grade, in english?  What are the differences and similarities between the three textbooks seen from a multimodal perspecive? The result showed that there was an interaction between the different types of text types and the images, in all three textbooks. The heading of each chapter is a clue to what the content of the text will be about. The images are well connected to the text and they also reenforce the content of the text. This connection between the pictures used in the chapter and the text can help readers better understand the content of the text.

Syftet med föreliggande studie var att undersöka hur lärare i svenskämnet i grundskolans F–3 ser på multimodalt arbete, det vill säga kombinationen av meningsskapande uttrycksformer. Till följd av samhällets utveckling och den digitala teknikens expansion har tillgängligheten av meningsskapande resurser ökat för dagens barn. I och med detta har multimodalt lärande, vilket innefattar kunskap om att läsa, skriva och tolka olika former av texter, fått en alltmer central roll i undervisningen. Föreliggande studie baserades på 52 respondenters svar som undersöktes via en webbenkät innehållande både kvantitativa och kvalitativa frågeställningar. Vidare har insamlade data analyserats och diskuterats genom socialsemiotisk teori. Studiens resultat visade på en rad olika sätt som modaliteter kan användas på och kombineras i undervisningen för att verka meningsskapande. Lärarna i studien angav att talat och skrivet språk samt bild var de mest använda modaliteterna i undervisningen, medan sång, drama och färg var minst förekommande. Slutsatsen av studien är att de tillfrågade lärarna var positivt inställda till och såg en rad fördelar med multimodalt arbete. / The purpose of the present study was to investigate how teachers of Swedish in primary school F–3 view multimodal work, i.e. the combining of meaning-making forms of expression. As a result of the development of society and the expansion of digital technology, the availability of meaning-making resources has increased for today's children. As a result, multimodal learning, which includes knowledge of reading, writing and interpreting various forms of texts, has acquired an increasingly central role in teaching. The present study is based on 52 respondents' answers that were examined through an online survey containing both quantitative and qualitative questions. Furthermore, the collected data has been analyzed through a lens of social semiotic theory. The results of the study show several different ways that modalities can be used and combined in teaching to create meaning. The teachers in the study state that spoken and written language as well as images are the most frequently used modalities in teaching, while song, drama and color are the least common ones. The conclusion of the study is that the teachers included in the study were positive towards and saw several benefits of multimodal work.

Den moderna informations- och kommunikationsteknologin har inneburit genomgripande för­änd­ringar av vårt sätt att leva och kommunicera men nya tekniker har också mötts av skepti­cism och väckt kontroverser. Ett aktuellt exempel är motståndet mot den femte genera­tion­ens mobil­nät, 5G. Trots att det inom den etablerade vetenskapen saknas stöd för att 5G skulle utgöra en hälsofara har en växande antistrålningsrörelse hävdat att tekniken för med sig nya och ökade strålningsrisker. I den här uppsatsen utforskas den svenska 5G-kritiska rörel­se som vuxit sig stor på Facebook. Syftet är att undersöka hur risk, rädsla och misstro i relation till mobilnätet 5G konstrueras diskursivt inom den 5G-kritiska rörelsen, med utgångspunkt i två av de största och mest aktiva 5G-kritiska grupperna på plattformen. Uppsatsen utgår från en socialkon­struk­tionistisk ansats och fokuserar tre analytiska teman: risk, rädsla och misstro. Dessa teman ligger även till grund för det teoretiska ramverket som utgår från Ulrich Becks (2012) risksamhälle och Frank Furedis (2006) teori om rädslokulturer. Studien bygger på en netnografisk insam­lings­metod där såväl språkligt som visuellt innehåll har samlats in och analyserats i en multi­modal diskursanalys. Analysresultaten visar att risk, rädsla och misstro konstru­eras via ”version­er av världen” där riskerna med 5G framställs som verkliga, akuta och hotande och där makt­hav­ande aktörer porträtteras som opålitliga, korrupta och in­kom­­petenta. Dessa diskur­s­iva mönster är såväl språk­­liga som visu­ella; de sker inte bara genom menings­skapande ord­val, narrativ och tecken utan också genom använd­ning av så kallade inter­net­mem och emojis. Studiens resultat visar också att sociologiska perspektiv på risk, rädsla och misstro kan fördjupa förståelsen för dessa konstruk­tioner och ge perspektiv på hur rörelsen förhåller sig till det omgivande sam­hället. Analysen tyder på att de definitions­strider och olika rationalitets­anspråk som Beck (2012) har beskriv­it som typiska för risksam­hället också präglar konstruk­tionen av riskerna med 5G. Furedis (2006) rädsloteman fördjupar vidare förståelsen för hur risker till­skrivs ett hotfullt innehåll genom sociala och kulturella pro­cesser. Dessutom visar analysen på att misstro gentemot etablerad expertis kan leda till fram­växten just den alter­na­tiva expertis som såväl Beck som Furedi har beskrivit. Samtidigt tycks social organi­sering online också innebära vissa nya förutsättningar som har potential att för­flytta tradi­tion­ella makt­positioner som finns beskriv­na i teorin. / Modern information and communications technology has brought about radical changes in the way we live and communicate. However, new technologies have also sparked scepticism and created controversies. A recent example is the opposition to the fifth-generation mobile network technology, 5G. According to the established science community, there is no evidence that 5G would pose a health hazard. Still, a growing anti-radiation movement has claimed that the tech­nology will cause new and increased radiation risks. This essay explores the Swedish 5G critical movement that has grown large on Facebook. The aim is to examine how risk, fear, and mistrust in relation to the mobile network 5G are constructed discursively within the 5G critical move­ment, based on two of the largest and most active 5G critical groups on the platform. Drawing on a social constructionist approach, the study focuses on three analytical themes: risk, fear, and mistrust. These themes also form the basis of the theoretical framework, consisting of per­spec­tives from Ulrich Beck’s (2012) risk society and Frank Furedi’s (2006) theory on culture of fear. The study is based on a netnographic collection method where both linguistic and visual data have been collected and analysed in a multimodal discourse analysis. The result of the analysis shows that risk, fear, and mis­trust are constructed via "versions of the world" in which the risks of 5G are presented as real, acute, and threat­ening and actors in power are portrayed as unreliable, corrupt, and incom­petent. These discursive patter­ns are both linguistic and visual; they take place not only through mean­­­ingful choices of words, narra­tives, and signs but also by using so-called internet memes and emojis. The results also show that sociological perspectives on risk, fear, and mis­trust can deepen the understanding of these construc­tions and provide perspectives on how the move­ment relates to the surrounding society. The analysis indicates that the definitional strugg­les and different claims of rationality that Beck (2012) has described as typical for the risk society also characterize the construction of risks related to 5G. Furedi’s (2006) themes of fear also deepens the understanding of how risks are assigned a threat­ening content through social and cult­ural processes. Moreover, the analysis reveals that distrust of established expert­ise can lead to the emergence of an alter­native expert­ise, which has been described by both Beck and Furedi. However, the results also suggest that social organization online entails some new con­ditions that have the potential to shift trad­itional positions of power described in theory.
