Posttraumatic Stress Disorder (PTSD) has been demonstrated as the primary pathway through which morbidity and mortality is achieved post-trauma. However, less is known about protective factors to PTSD, depression, and self-reported health outcomes of adults following a traumatic event. Through examination of residential fire survivors, the current project evaluated the predictive validity of protective factors of PTSD as they relate to PTSD, depression, and somatic health outcomes. Additionally, the project collapsed the three outcomes variables into a unified health construct and evaluated protective factors ability to predict health. It was hypothesized the peritraumatic emotionality, social support, and resource loss would predict PTSD, depression, and somatic health. Additionally, it was predicted that peritraumatic emotionality, social support, and resource loss would predict a unified construct of health. Participants were assessed via self-report and semi-structured interviews approximately four months post-fire. Results of the current project demonstrated strong associations amongst peritraumatic emotionality and resource loss for many of the outcome variables. However, social support was not found to be a predictor of any of the outcomes variables. When evaluating the unified health construct, resource loss was found to significant predict a resilient group of trauma survivors four months post-fire. The present study suggests lower peritraumatic emotionality and lower sustained resource loss are significant protective factors for resiliency from trauma. / Ph. D.

[pt] Linhagens de animais são bastante usadas para investigar as bases genéticas de várias desordens psiquiátricas. No primeiro estudo deste trabalho, desenvolveu-se ao longo de três gerações, duas linhagens de ratos para reagirem com alta (Cariocas com Alto Congelamento - CAC) ou baixa (Cariocas com Baixo Congelamento - CBC) resposta condicionada de congelamento a estímulos contextuais previamente associados a choques elétricos. Um segundo estudo investigou os efeitos de lesões eletrolíticas no complexo amigdalóide sobre a resposta condicionada de congelamento nestas duas linhagens de animais. Ratos controles, que não pertenciam a estas linhagens, foram usados para determinar uma linha de base da resposta de congelamento. Lesões foram feitas após a fase de aquisição, quando os ratos receberam 3 choques não sinalizados numa caixa de condicionamento. Lesões falsas foram feitas em ratos dos três grupos. Resultados mostraram que as lesões na amígdala diminuíram a resposta de congelamento nos três grupos. Os resultados também mostraram que lesões na amígdala produziram efeitos semelhantes nas linhagens CAC e CBC. Estes resultados são discutidos levando-se em conta possíveis circuitos neurais envolvidos na resposta de congelamento. / [en] Animal selected lines are often used to investigate the genetic basis of many psyquiatric disorders. In the first study of this work, selected lines of rats with high (Carioca High freezing- CHF) and low (Carioca Low Freezing- CLF) conditioned freezing to contextual cues previously associated with electric shocks were developed. In a second study, the effect of amygdaloid electrolytic lesions on conditioned freezing was investigated in these two selected lines. Control rats, which did not belong to the selected lines, were employed to determine conditioned freezing baseline. Lesions were made after the acquisition phase, when the rats received 3 unsignaled shocks in a conditioning chamber. Sham lesions were made in rats of all groups. Results indicated that the amygdaloid lesions decreased the freezing response in all the groups of animals. Results also revealed that the amigdaloid lesions produced similar effects in the CHF and CLF lines. These results are discussed in terms of possible neural circuitry involved in freezing response.

This essay argues that Sara Ahmed’s methodology for reading the emotionality of texts, through its focus on the relationships between emotions, language and bodies, can be applied to the emotional responses of Australians to refugees and asylum seekers. This essay specifically focuses on the emotions of disgust and pain in the participants of Go Back To Where You Came From, a three-part Australian documentary/realia TV series, because these two emotions’ preoccupation with surface and proximity provide a useful metaphor for what can be observed in the participants’ emotionality. Sensuous proximity in the form of sight, taste, smell, touch and hearing underlies the disgust experienced by the Go Back participants, while shared surfaces enable the participants to feel the pain of others. The essay concludes that Ahmed’s methodology is indeed an effective tool for analysing the emotions of people “affected” by the transnational movements of others.

Although the 'affective turn' in social sciences lead to a new understanding of the effects of emotions on society, the role of emotions in media remains scarcely researched. Purpose of this study is to shed light on emotions in global television news and the ways in which gendered and racialized power relations may shape, and may be shaped by, emotional practices and discourses. Precisely because emotions play a significant function in discourses of political conflict, focus here is the coverage of political dissent, specifically the coverage of the 2017 Unite the Right rally in the two global television channels CNN International and Al-Jazeera English. The study thus builds on literature on emotions and political struggles, and literature on emotions in the media, to apply the questions posed therein to the medium global television. Analyzing broadcast items, this study employs a mixed method approach that combines a quantitative content analysis with a qualitative analysis of broadcast items grounded in Teun A. van Dijk’s tradition of critical discourse analysis, within an analytical framework that privileges emotions. The findings reveal an unequal distribution of voice in the coverage of both channels, which in connection with emotion practices and discourses, establishes a marginalization of voice along the lines of race, class, and gender. Accordingly, the study gives an account of the representation of voice, race, and emotions in the coverage of the Unite the Right rally, and establishes the importance of studying emotions in media in relation to these concepts.

[pt] Criação seletiva bidirecional de uma resposta defensiva ou qualquer outra característica fenotípica é uma técnica na qual animais são criados com o objetivo de modificar a frequência dos genes que estão subjacentes a um fenótipo em particular. O acasalamento de animais de uma determinada população com base nos extremos opostos de uma característica observável vai propagar, após diversas gerações, este fenótipo particular em direções opostas, levando-se à criação de duas linhagens contrastantes. No presente trabalho empregamos o congelamento condicionado em resposta a estímulos contextuais previamente associados com choques elétricos nas patas como critério de seleção para o desenvolvimento de duas novas linhagens de ratos. O protocolo básico consistiu de acasalamento entre machos e fêmeas Wistar com as maiores e as menores taxas de congelamento condicionado em resposta a sinais contextuais da câmara experimental onde os animais foram expostos a três choques elétricos não sinalizados no dia anterior. O Estudo 1 apresenta os resultados iniciais de quatorze gerações de criação seletiva. Os resultados mostraram que diferenças significativas entre estas duas linhagens foram encontradas após 3 gerações, indicando um forte componente hereditário deste tipo de aprendizagem. As linhagens foram denominadas Cariocas com Alto Congelamento Condicionado (CAC) e Cariocas com Baixo Congelamento condicionado (CBC). Além disso, nós introduzimos um terceiro grupo de animais aleatoriamente selecionados (CTRL) em nosso programa de criação seletiva. No Estudo 2 investigamos os diferentes padrões de extinção e da reaquisição do medo condicionado nestas duas novas linhagens. Por fim, no Estudo 3, nossos resultados sugeriram uma dissociação entre o medo contextual e o medo discreto entre animais CAC e CBC. / [en] Bidirectional selective breeding of a defensive response or any other phenotypic characteristic is a technique in which animals are bred to modify the frequency of the genes that underlie a particular phenotype. Mating animals within a population based on the opposite extremes of an observable characteristic will push, over many generations, this particular phenotype in opposite directions, leading to two separately bred lines. In the present work we employed the conditioned freezing in response to contextual cues previously associated with footshock as the phenotype criterion for developing two new rat lines. The basic protocol consisted of mating male and female albino Wistar rats with the highest and lowest conditioned freezing in response to the contextual cues of the experimental chamber where animals were exposed to three unsignaled electric footshocks on the previous day. Study 1 presents the initial results of fourteen generations of selective breeding. We found that after three generations, reliable differences between these two lines were already present, indicating a strong heritable component of this type of learning. The lines were named Carioca High conditioned Freezing (CHF) and Carioca Low conditioned Freezing (CLF). Also, we introduced a third group of randomly selected animals (RND) in our selective breeding program. In Study 2, we investigated the different patterns of fear extinction and reacquisition in these two new lines. Finally, in Study 3, results showed dissociation between contextual and phasic fear between CHF and CLF rats.

The aim of this research is to explore the association between brand personality traits and sonic logos. The brand personality traits that are incorporated into this research are Responsibility, Activity, Aggressiveness, Simplicity and Emotionality. These traits constitute one of the two building blocks for this research. The other building block consists of the sonic logo, but more specifically, variations in mode and tempo. Because the research was exploratory in nature, a qualitative research strategy was deemed appropriate. Additionally, in order to explore the association between the two building blocks, one sonic logo was created in four versions where the mode and tempo shifted in different combinations. Semi-structured interviews were then conducted where the sonic logos were played. To find associations and patterns in the empirical material, coding inspired from grounded theory were used. To conclude, the first sonic logo version shows associations to the Activity and Emotionality dimensions. The second sonic logo version shows associations to the Responsibility, Aggressiveness and Activity dimensions. The third sonic logo version shows associations to the Activity, Simplicity and Emotionality dimensions. Lastly, the fourth sonic logo version shows associations to the Responsibility, Aggressiveness and Emotionality dimensions.
