"We´re Not Gonna Take It Anymore" : Kränkning, moralpanik och populärmusikalisk diskurs / “We´re Not Gonna Take It Anymore” :  Offence, moral panics andpopular music discourse

Salman, Liljan January 2024 (has links)
Denna uppsats utforskar den intrikata dynamiken av sociala och kulturella kontroverser inom populärmusikalisk diskurs med specifikt fokus på kränkningar och deras konsekvenser. Genom en kvalitativ låttextanalys av fyra låtar från Parents Music Resource Centers (PMRC) ”The Filthy Fifteen”, diskuterar denna studie samspelet mellan kränkning, moralpanik, kulturkrig och yttrandefrihet ur kritiska perspektiv. Genom att utforska dessa spridda men sammanhängande ämnen med hermeneutik och intersektionalitet som teoretiska verktyg, eftersträvar uppsatsen att synliggöra utmaningarna som artister, organisationer och musiklyssnare står inför, den känsliga balansen mellan individuella och kollektiva uttryck av kränkningar.

Towards Climate Based Early Warning and Response Systems for Malaria

Sewe, Maquins Odhiambo January 2017 (has links)
Background: Great strides have been made in combating malaria, however, the indicators in sub Saharan Africa still do not show promise for elimination in the near future as malaria infections still result in high morbidity and mortality among children. The abundance of the malaria-transmitting mosquito vectors in these regions are driven by climate suitability. In order to achieve malaria elimination by 2030, strengthening of surveillance systems have been advocated. Based on malaria surveillance and climate monitoring, forecasting models may be developed for early warnings. Therefore, in this thesis, we strived to illustrate the use malaria surveillance and climate data for policy and decision making by assessing the association between weather variability (from ground and remote sensing sources) and malaria mortality, and by building malaria admission forecasting models. We further propose an economic framework for integrating forecasts into operational surveillance system for evidence based decisionmaking and resource allocation.  Methods: The studies were based in Asembo, Gem and Karemo areas of the KEMRI/CDC Health and Demographic Surveillance System in Western Kenya. Lagged association of rainfall and temperature with malaria mortality was modeled using general additive models, while distributed lag non-linear models were used to explore relationship between remote sensing variables, land surface temperature(LST), normalized difference vegetation index(NDVI) and rainfall on weekly malaria mortality. General additive models, with and without boosting, were used to develop malaria admissions forecasting models for lead times one to three months. We developed a framework for incorporating forecast output into economic evaluation of response strategies at different lead times including uncertainties. The forecast output could either be an alert based on a threshold, or absolute predicted cases. In both situations, interventions at each lead time could be evaluated by the derived net benefit function and uncertainty incorporated by simulation.  Results: We found that the environmental factors correlated with malaria mortality with varying latencies. In the first paper, where we used ground weather data, the effect of mean temperature was significant from lag of 9 weeks, with risks higher for mean temperatures above 250C. The effect of cumulative precipitation was delayed and began from 5 weeks. Weekly total rainfall of more than 120 mm resulted in increased risk for mortality. In the second paper, using remotely sensed data, the effect of precipitation was consistent in the three areas, with increasing effect with weekly total rainfall of over 40 mm, and then declined at 80 mm of weekly rainfall. NDVI below 0.4 increased the risk of malaria mortality, while day LST above 350C increased the risk of malaria mortality with shorter lags for high LST weeks. The lag effect of precipitation was more delayed for precipitation values below 20 mm starting at week 5 while shorter lag effect for higher precipitation weeks. The effect of higher NDVI values above 0.4 were more delayed and protective while shorter lag effect for NDVI below 0.4. For all the lead times, in the malaria admissions forecasting modelling in the third paper, the boosted regression models provided better prediction accuracy. The economic framework in the fourth paper presented a probability function of the net benefit of response measures, where the best response at particular lead time corresponded to the one with the highest probability, and absolute value, of a net benefit surplus.  Conclusion: We have shown that lagged relationship between environmental variables and malaria health outcomes follow the expected biological mechanism, where presentation of cases follow the onset of specific weather conditions and climate variability. This relationship guided the development of predictive models showcased with the malaria admissions model. Further, we developed an economic framework connecting the forecasts to response measures in situations with considerable uncertainties. Thus, the thesis work has contributed to several important components of early warning systems including risk assessment; utilizing surveillance data for prediction; and a method to identifying cost-effective response strategies. We recommend economic evaluation becomes standard in implementation of early warning system to guide long-term sustainability of such health protection programs.

Trigger warnings: likabehandling eller ett hot mot utbildningsväsendet? : en argumentationsanalys av den svenska offentliga debatten

Widlund, Benjamin January 2016 (has links)
Trigger warnings as a concept is mainly a tool to make students aware of potentially triggering content in literature and has its origin in internet adaptions of psychological theories of posttraumatic stress disorder. The aim of this essay was to describe and analyse the argumentation in the public debate over trigger warnings in Sweden and to illustrate the fundamental questions relating to education that is highlighted by it. This was done through argumentation analysis and with theories of liberalism and identity politics as poles of a dimension of justice, illustrated by two different perspectives on disability pedagogy. The material chosen consisted of nine articles, radio programs and televised debates. The results show a clear tendency for advocates of trigger warnings to lean towards identity politics and a critical perspective on disability pedagogy in their argumentation, while the critics firmly represented a liberal, universalist perspective along with a compensatory perspective on disability pedagogy in theirs. Three fundamental questions arose in the debate: first, safety in the realm of education, meant as void of feelings of being offended, was viewed as essential by the authors who were pro trigger warnings and as a threat to the sole purpose of education by those who were against it. Second, the importance of a diagnosis for disability pedagogy, where those against stressed the importance of a diagnosis, the lack of which in combination with a request for a trigger warning was viewed as being easily offended. Advocates on the other hand were uninterested in diagnoses. Finally, the relation between free speech and democratic values in the educational system and in the society as a whole, where those authors favouring trigger warnings tended to view free speech as less fundamental than those opposed, who instead saw trigger warnings as a threat.

Misinformation and Need for Cognition: How They Affect False Memories

Antonio, Lilyeth 01 January 2015 (has links)
The purpose of this study was to gain a better understanding of false memories and Need for Cognition (NFC). The relationship was examined using a typical misinformation paradigm where participants viewed a video clip which depicted a museum burglary and were later presented with an auditory narrative that contained misleading information about the video they previously saw. Half of the participants were exposed to warnings of misinformation. Additionally, the effect of question type (e.g., central, peripheral, and neutral) was taken into account. A main effect for NFC was found indicating that high NFC individuals had fewer false memories for the originally witnessed event than low NFC individuals. It was also found that memory for central details was better than for peripheral details. Furthermore, an interaction between warning and question type showed that when a warning was present, memory for the misleading peripheral details was stronger. Overall, the results demonstrate that there is a difference between high and low NFC individuals and the way memory is processed in the misinformation paradigm. Additionally, the results of this study reaffirm the notion that post-event information can hinder an eyewitness’s memory for an original event.

Comparaison de systèmes de traduction automatique pour la post édition des alertes météorologique d'Environnement Canada

van Beurden, Louis 08 1900 (has links)
Ce mémoire a pour but de déterminer la stratégie de traduction automatique des alertes météorologiques produites par Environnement Canada, qui nécessite le moins d’efforts de postédition de la part des correcteurs du bureau de la traduction. Nous commencerons par constituer un corpus bilingue d’alertes météorologiques représentatives de la tâche de traduction. Ensuite, ces données nous serviront à comparer les performances de différentes approches de traduction automatique, de configurations de mémoires de traduction et de systèmes hybrides. Nous comparerons les résultats de ces différents modèles avec le système WATT, développé par le RALI pour Environnement Canada, ainsi qu’avec les systèmes de l’industrie GoogleTranslate et DeepL. Nous étudierons enfin une approche de postédition automatique. / The purpose of this paper is to determine the strategy for the automatic translation of weather warnings produced by Environment Canada, which requires the least post-editing effort by the proofreaders of the Translation Bureau. We will begin by developing a bilingual corpus of weather warnings representative of this task. Then, this data will be used to compare the performance of different approaches of machine translation, translation memory configurations and hybrid systems. We will compare the results of these models with the system WATT, the latest system provided by RALI for Environment Canada, as well as with the industry systems GoogleTranslate and DeepL. Finaly, we will study an automatic post-edition system.

Designing Multimodal Warning Signals for Cyclists of the Future

Nordmark, Anton January 2019 (has links)
Traffic is a complex environment in which many actors take part; several new technologies bring promises of reducing this complexity. However, cyclists—a particularly vulnerable road user group—have so far been somewhat put aside in these new developments, among them being Cooperative Intelligent Traffic Systems (C-ITS) and their aspects of human–computer interaction. This master’s thesis of industrial design engineering presents five multimodal collision warning signals for cyclists—future ones in these supposed C-ITS—using a novel application of bone conduction headphones (BCH) via sensations of both sound and touch. The thesis project was conducted as a complementary subset of the larger research project ‘V2Cyclist’ orchestrated by RISE Interactive. V2Cyclist set out to adapt the wireless V2X-protocol for cyclists by developing a physical prototype in the form of a bicycle helmet and corresponding human–computer interface. A significant part of the theoretical framework for this thesis was multiple resource theory: tasks in a different modality can be performed more effectively than in one already taxed attentively. Literature on human factors was also applied, particularly with regards to the perception of sound; evidence suggests that humans evolved a perceptual bias for threatening and ‘looming’ sounds that appear to encroach our peripersonal space; ethological findings point toward the association with low-frequency sounds to largeness. Sound design techniques usually applied to more artistic ends, such as synthesis and mixing, were repurposed for the novel, audiotactile context of this thesis. The thesis process was rooted in design thinking and consisted of four stages: context immersion, ideation, concept development, and lastly evaluation; converging and diverging the novel design space of using BCH in an audiotactile, i.e. bimodal way. The divergent approach generated a wide range of ideas. The later convergent approach did not result in one, definite design as further evaluation is required but also due to unknowns in terms of future hardware and network constraints. Given the plurality and diversity of cyclists, it may well follow that there is no optimal collision warning design in the singular. Hence, a range of five different solutions is presented. Each of the five multimodal collision warnings presents a different approach to conveying a sense of danger and urgency. Some warning signals are static in type, while others are more dynamic. Given the presumed rarity of collision warnings, multiple design techniques and rationales were applied separately, as well as in combination, to create different warning stimuli that signaled high urgency in an intuitive way. Namely, the use of: conventions in design and culture; explicitness in the form of speech; visceral appeal via threatening and animalistic timbres; dynamic and procedurally generated feedback; multimodal salience; crossmodal evocation of ‘roughness;’ size-sound symbolism to imply largeness; and innately activating characteristics of looming sounds. / Trafiken är en komplex miljö med många deltagare; diverse ny teknik gör anspråk på att underlätta denna komplexitet. Men, cyklister—en särskilt utsatt grupp av trafikanter—har hittills hamnat i skymundan för sådana utvecklingar. Vidare, aspekten av användbara gränssnitt för cyklister inom sådana uppkopplade och samverkande trafiksystem (C-ITS) har utforskats desto mindre. Det här examensarbetet inom Teknisk design presenterar fem multimodala kollisionsvarningar avsedda för cyklister—framtida sådana i dessa C-ITS—genom en ny och bimodal användning av benledande hörlurar via både ljud och vibrationer. Examensarbetet genomfördes i koppling till forskningsprojektet V2Cyclist, orkestrerat av RISE Interactive, vars projektmål var att anpassa det trådlösa kommunikationsprotokollet V2X för cyklister via en fysisk prototyp i form av en cykelhjälm och parallellt utveckla ett tillhörande användargränssnitt. En viktig del av det teoretiska ramverket för det här examensarbetet grundar sig på multiple resource theory: uppgifter kan utföras mer effektivt i en annan modalitet än i en som redan är belastad med uppmärksamhet. Mänskliga faktorer och teori om vår uppfattning användes; bevis pekar på att människor har evolutionärt utvecklat en bias för hotande ljud som upplevs inkräkta på vårt närmsta personliga revir; etologiska rön visar på en koppling mellan lågfrekventa ljud och ‘storhet.’ Tekniker inom ljuddesign vanligtvis använda till mer artistiska ändamål, såsom syntes och mixning, användes här till godo för att utforska den nya och bimodala designrymden. Processen för arbetet grundade sig i design thinking och bestod av fyra faser: kontextfördjupning, idégenerering, konceptutveckling, och utvärdering. En ny och tidigare outforskad designrymd beståendes av en bimodal, ljudtaktil användning av benledande hörlurar divergerades och konvergerades. Ett initialt utforskande angreppssätt gav upphov till en bred mängd av idéer. Ett senare renodlande angreppssätt gick, dock, inte hela vägen till endast en optimal lösning, då vidare utvärdering krävs men också på grund av okända teknologiska begränsningar. Dessutom, givet cyklisters stora mångfald, kan det möjligtvis följa att det inte finns någon enskild design av den optimala kollisionsvarningen. Ett spann på fem olika lösningar presenteras därmed. Fem koncept för multimodala kollisionsvarningar presenteras där varje variant uttrycker fara och kritiskhet på olika sätt. Vissa är statiska i typ, medan andra verkar mer kontinuerligt och dynamiskt. Det antogs att kollisionsvarningar sker sällan. Olika designtekniker och motiveringar har använts, ibland i kombination med varandra, för att skapa kollisionsvarningar vars avsikter omedelbart förstås: normer inom design och kultur gällande ljud; uttalad kommunikation i form av tal; anspråk på människors biologiska intuition via hotfulla och djurliknande klangfärger; dynamisk och procedurellt genererad feedback; multimodal effektfullhet; korsmodal känsla av grova texturer; size-sound symbolism för att antyda ‘storhet;’ samt de naturligt aktiverande egenskaperna hos looming sounds.

Cracked skulls and social liability : relating helmet safety messages to motorcycle riders

Voight, Susan Amy 02 April 2014 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Grounded theory analysis, informed by a socio-cultural lens, was applied to the narratives of eighteen motorcycle riders in order to understand, from the rider’s perspective, receptivity to warning messages regarding motorcycle helmet use. This study relied upon narrative analysis to identify patterns in communication that surround motorcycle riders’ experiences. Socio-cultural cues identified importance in the process of interest development in motorcycle riding, search for information regarding motorcycle riding, response to danger within the motorcycle riding experience, and attitude toward protection messages. Narratives specific to danger, or experiences of motorcycle accidents were analyzed for comparison with fear appeal theory. Special focus was applied to Terror Management Theory (TMT) and applied to the communication surrounding the real experiences of motorcycle accident and the perceived threat of danger while motorcycle riding. Communication evidencing relational influence was examined for examples of socially constructed interpretation of social identity and an individual rider's perspective of their lifeworld. The analysis revealed evidence of the TMT concept of burying or denying thoughts of danger. The TMT concept of lifeworld influence on behavior was evidenced in riders who did not accept warning messages involving helmet use. Examples of attitude and behavior change where present in two study participants’ narratives that described experience of severe injury and also the death of a friend. The riders cited these occurrences as experiences that inhibited their previous behavior of placing thoughts of motorcycle injury and death in the back of mind. Although small in number, this participant group offered multiple categorizations of rider descriptions. The narratives offered distinction in time of life when riding interest developed. As well, motorcycle training facilities were often noted as a source of communication from which riders obtained influence on their future behaviors. From this information insight was gained to offer suggestions for future research on time of message delivery. Riders who develop interest in riding as adults represent a category on which to focus preliminary educational messages. Individuals who have not yet developed an interest in motorcycle riding may benefit from societal cues that demonstrate safe riding behavior. Future research in mass media appeals focused on motorcycle riders are suggested, as is development of educational programs for delivery to high school audiences.
