Marguerite Duras (1914−1996) was one of the most original French writers and film directors, whose cycles are renowned for a transgeneric repetition variation of human suffering in the modern condition. Her fictionalisation of Asian colonialism, the India Cycle (1964−1976), consists of three novels, Le ravissement de Lol V. Stein (1964), Le Vice-consul (1966) and L'amour (1971), a theatre play, India Song (1973), and three films, La Femme du Gange (1973), India Song (1974) and Son nom de Venise dans Calcutta desért (1976). Duras’s cultural position as a colon in inter-war ‘Indochina’ was the backdrop for this “théâtre-text-film”, while its creation was provoked by the atrocities of World War II and post-war decolonisation. Fictionalising Trauma analyses the aesthetics of the India Cycle as Duras’s critical working-through of historical trauma. From an emotion-focused cognitive viewpoint, the study sheds light on trauma’s narrativisation using the renewed concept of traumatic memory developed by current social neuroscience. Duras is shown to integrate embodied memory and narrative memory into an emotionally progressing fiction. Thus the rhetoric of the India Cycle epitomises a creative symbolisation of the unsayable, which revises the concept of trauma from a semiotic failure into an imaginative metaphorical process. The India Cycle portrays the stagnated situation of a white society in Europe and British India during the thirties. The narratives of three European protagonists and one fictional Cambodian mendicant are organised as analogues mirroring the effects of rejection and loss on both sides of the colonial system. Using trauma as a conceptual prism, the study rearticulates this composition as three roles: those of witnessing writers, rejected survivors and colonial perpetrators. Three problems are analysed in turn by reading the non-verbal markers of the text: the white man as a witness, the subversive trope of the madwoman and the deadlock of the colonists’ destructive passion. The study reveals emotion and fantasy to be crucial elements in critical trauma fiction. Two devices intertwine throughout the cycle: affective images of trauma expressing the horror of life and death, and self-reflexive metafiction distancing the face-value of the melodramatic stories. This strategy dismantles racist and sexist discourses underpinning European life, thus demanding a renewal of cultural memory by an empathic listening to the ‘other’. And as solipsism and madness lead the lives of the white protagonists to tragic ends, the ‘real’ beggar in Calcutta lives in ecological harmony with Nature. This emphasises the failure of colonialism, as the Durasian phantasm ambiguously strives for a deconstruction of the exotic mythical fiction of French ‘Indochina’.

This project has investigated how the architecture of the blood vessels supplying nutrients to skeletal muscles is affected by muscle contusion injuries, and how it changes during healing with or without initial treatment of the injury by icing. In order to do this, we used contrast agents to visualise blood vessels in 3D with micro-computed tomography imaging. This research significantly contributes to the fields of orthopaedics, traumatology and sports medicine, as it improves our understanding of muscle contusion injuries. Furthermore, the methods developed in this thesis may help to improve the diagnosis and monitoring of these injuries.

The occurrence and nature of civilian firearm- and explosion-injuries in Finland, and the nature of severe gunshot injuries of the extremities were described in seven original articles. The main data sources used were the National Hospital Discharge Register, the Cause-of-Death Register, and the Archive of Death Certificates at Statistics Finland. The present study was population based. Epidemiologic methods were used in six and clinical analyses in five papers. In these clinical studies, every original hospital record and death certificate was critically analyzed. The trend of hospitalized firearm injuries has slightly declined in Finland from the late 1980s to the early 2000s. The occurrence decreased from 5.1 per 100 000 person-years in 1990 to 2.6 in 2003. The decline was found in the unintentional firearm injuries. A high incidence of unintentional injuries by firearms was characteristic of the country, while violence and homicides by firearms represented a minor problem. The incidence of fatal non-suicidal firearm injuries has been stable, 1.8 cases per 100 000 person-years. Suicides using firearms were eight times more common during the period studied. This is contrary to corresponding reports from many other countries. However, the use of alcohol and illegal drugs or substances was detected in as many as one-third of the injuries studied. The median length of hospitalization was three days and it was significantly associated (p<0.001) with the type of injury. The mean length of hospital stay has decreased from the 1980s to the early 2000s. In this study, there was a special interest in gunshot injuries of the extremities. From a clinical point of view, the nature of severe extremital gunshot wounds, as well as the primary operative approach in their management, varied. The patients with severe injuries of this kind were managed at university and central hospital emergency departments, by general surgeons in smaller hospitals and by cardiothoracic or vascular surgeons in larger hospitals. Injuries were rarities and as such challenges for surgeons on call. Some noteworthy aspects of the management were noticed and these should be focused on in the future. On the other hand, the small population density and the relatively large geographic area of Finland do not favor high volume, centralized trauma management systems. However, experimental war surgery has been increasingly taught in the country from the 1990s, and excellent results could be expected during the present decade. Epidemiologically, explosion injuries can be considered a minor problem in Finland at present, but their significance should not be underestimated. Fatal explosion injuries showed up sporadically. An increase occurred from 2002 to 2004 for no obvius reason. However, in view of the historical facts, a possibility for another rare major explosion involving several people might become likely within the next decade. The national control system of firearms is mainly based on the new legislations from 1998 and 2002. However, as shown in this study, there is no reason to assume that the national hospitalization policies, or the political climate, or the legislation might have changed over the study period and influenced the declining development, at least not directly. Indeed, the reason for the decline to appear in the incidence of unintentional injuries only remains unclear. It may derive from many practical steps, e.g. locked firearm cases, or from the stability of the community itself. For effective reduction of firearm-related injuries, preventive measures, such as education and counseling, should be targeted at recreational firearm users. To sum up, this study showed that the often reported increasing trend in firearm as well as explosion-related injuries has not manifested in Finland. Consequently, it can be recognized that, overall, the Finnish legislation together with the various strategies have succeeded in preventing firearm- and explosion-related injuries in the country.

Stone Baby: An Exploration of Affect and Trauma in Visual Art was held at the Block, QUT Creative Industries Precinct on August 27-28, 2014. At the conclusion of my Masters project, this exhibition was a showcase of the outcomes of my material and digital explorations in the form of installation, sculpture and film. My primary motivation can be described as a relational and ethical attempt to find a balance between the erotic and the aggressive. This is experienced in the self as feelings of attraction and repulsion in response to the new and unknown "other". Consequently creative practice is necessarily a complex affair that is experienced as a completely immersive and self-contained psychological space. It is within this space that both physical sensation and raw emotion are able to tangibly and conceptually interact with psychoanalytic theory, and concrete materials video and sound.

Objective: To describe the prevalence and demographic, clinical and functional correlates of childhood trauma in patients attending early psychosis clinics. Method: Participants were recruited from outpatients attending four early psychosis services. Exposure to childhood trauma was assessed using the Childhood Trauma Questionnaire (CTQ). Psychopathology was measured using the Positive and Negative Syndrome Scale and the Depression, Anxiety and Stress Scale. Social and vocational functioning and substance use were also assessed. Results: Over three-quarters of the 100 patients reported exposure to any childhood trauma. Emotional, physical and sexual abuse were reported by 54%, 23% and 28% of patients, respectively, while 49% and 42% of patients reported emotional and physical neglect, respectively. Female participants were significantly more likely to be exposed to emotional and sexual abuse. Exposure to childhood trauma was correlated with positive psychotic symptoms and higher levels of depressive, anxiety and stress symptoms; however, it had no impact on social or vocational functioning or recent substance use. Conclusion: Exposure to childhood trauma was common in patients with early psychosis, and associated with increased symptomatology. Existing recommendations that standard clinical assessment of patients with early psychosis should include inquiry into exposure to childhood trauma are supported.

The purpose of this work is to use the concepts of human time and cultural trauma in a biographical study of the turning points in the recent history of Estonia. This research is primarily based on 148 in-depth biographical interviews conducted in Estonia and Sweden in 1995-2005, supplemented by excerpts from 5 collections and 10 individually published autobiographies. The main body of the thesis consists of six published and of two forthcoming separate refereed articles, summarised in the theoretical introduction, and Appendix of the full texts of three particular life stories. The topic of the first article is the generational composition and the collective action frames of anti-Soviet social mobilisation in Estonia in 1940-1990. The second article details the differentiation of the rites of passage and the calendar traditions as a strategy to adapt to the rapidly changed political realities, comparatively in Soviet Estonia and among the boat-refugees in Sweden. The third article investigates the life stories of the double-minded strategic generation of the Estonian-inclined Communists, who attempted to work within the Soviet system while professing to uphold the ideals of pre-war Estonia. The fourth article is concentrated on the problems of double mental standards as a coping strategy in a contradictory social reality. The fifth article implements the theory of cultural trauma for the social practice of singing nationalism in Estonia. The sixth article bridges the ideas of Russian theoreticians concerning cultural dialogue and the Western paradigm of cultural trauma, with examples from Estonian Russian life stories. The seventh article takes a biographical look at the logic of the unraveling of cultural trauma through four Soviet decades. The eighth article explores the re-shaping of citizen activities as a strategy of coping with the loss of the independent nation state, comparatively in Soviet Estonia and among Swedish Estonians. Cultural trauma is interpreted as the re-ordering of the society s value-normative constellation due to sharp, violent, usually political events. The first one under consideration was caused by the occupations of the Republic of Estonia by the Soviet army in 1940-45. After half a century of suppression the memories of these events resurfaced as different stories describing the long-term, often inter-generational strategies of coping with the value collapse. The second cultural trauma is revealed together with the collapse of the Soviet power and ideology in Estonia in 1991. According to empirical data, the following three trauma discourses have been reconstructed: - the forced adaptation to Soviet order of the homeland Estonians; - the difficulty of preserving Estonian identity in exile (Sweden); - the identity crisis of the Russian population of Estonia. Comparative analyses of these discourses have shown that opposing experiences and worldviews cause conflicting interpretations of the past. Different social and ethnic groups consider coping with cultural trauma as a matter of self-defence and create appropriate usable pasts to identify with. Keywords: human time, cultural trauma, frame analysis, discourse, life stories

Dry eye syndrome (DES) is a complex, multifactorial, immune-associated disorder of the tear and ocular surface. DES with a high prevalence world over needs identification of potential biomarkers so as to understand not only the disease mechanism but also to identify drug targets. In this study we looked for differentially expressed proteins in tear samples of DES to arrive at characteristic biomarkers. As part of a prospective case-control study, tear specimen were collected using Schirmer strips from 129 dry eye cases and 73 age matched controls. 2D electrophoresis (2DE) and Differential gel electrophoresis (DIGE) was done to identify differentially expressed proteins. One of the differentially expressed protein in DES is lacrimal proline rich 4 protein (LPRR4). LPRR4 protein expression was quantified by enzyme immune sorbent assay (ELISA). LPRR4 was down regulated significantly in all types of dry eye cases, correlating with the disease severity as measured by clinical investigations. Further characterization of the protein is required to assess its therapeutic potential in DES.

The evaluation of heated mussels by protein analysis makes clear that the methods used allow a differentiation between mussel tissues which had experienced different degrees of heating. It could be verifiyed by both, the analysis of enzyme activities and differential scanning calorimetry that the investigated trade products were only blanched and not completely well done cooked.

O presente trabalho investiga os diferentes processos sociais relacionados ao surgimento do transtorno de estresse pós-traumático (TEPT) no contexto brasileiro. Categoria diagnóstica norte-americana instituída na década de 1980 pela terceira edição do Manual Diagnóstico e Estatístico de Transtornos Mentais (Diagnostic and Statistical Manual of Mental Disorders DSM-III) uma publicação da Associação Americana de Psiquiatria (American Psychiatric Association APA) o TEPT tornou-se, desde a sua aparição, uma das categorias nosológicas mais difundidas, estudadas e diagnosticadas da psiquiatria contemporânea. A partir do cotidiano de um laboratório de pesquisa e tratamento do TEPT, de análises conversacionais dos atendimentos médicos, de um estudo das diferentes escalas psiquiátricas utilizadas no acompanhamento dos pacientes e de pesquisas sobre a mídia relacionada às experiências traumáticas buscou-se entender os entrelaçamentos entre os processos de difusão e a construção da legitimidade da categoria diagnóstica do TEPT. A abordagem aqui proposta pretende ir além do aparente dilema entre uma concepção medicalizada que assumem a existência o TEPT como um fenômeno natural e as abordagens sócio-antropológicas que veem o TEPT como uma experiência culturalmente construída. Por fim, pretendo mostrar, pela investigação dos alicerces políticos e culturais dos denominados transtornos mentais, que o estatuto social dos diagnósticos e dos tratamentos da moderna psiquiatria só pode ser compreendido tendo como referência as dinâmicas de longo prazo nas sociedades contemporâneas.

O transtorno de estresse pós-traumático (TEPT) é um transtorno de ansiedade que pode ser desenvolvido após a ocorrência de um evento traumático, e que costuma vir acompanhado de um significativo comprometimento da qualidade de vida. Indivíduos diagnosticados com o TEPT apresentam níveis de frequência cardíaca mais elevados em situações de exposição a eventos estressores, como sons e imagens que relembram a experiência traumática. No entanto, estudos que avaliaram a frequência cardíaca no momento do trauma como preditor do desenvolvimento de TEPT não apresentam resultados consistentes. Os objetivos deste trabalho foram: verificar se frequência cardíaca (FC) peritraumática de repouso, após exposição ao trauma, é um fator preditor para o desenvolvimento do TEPT e para a gravidade dos sintomas de TEPT em adultos. Foi realizada uma revisão sistemática, seguida de metanálise, utilizando-se as bases eletrônicas PUBMED, LILACS, PILOTS, PsycoINFO e Web of Science. Foram incluídos 17 estudos nesta revisão sistemática. Os resultados de dez estudos foram utilizados para a metanálise das diferenças de médias de FC combinada. Oito estudos foram utilizados para a metanálise das correlações entre a FC e a gravidade dos sintomas de TEPT. Modelos de meta-regressão foram ajustados para identificar variáveis que pudessem explicar a heterogeneidade entre os estudos. A FC peritraumática no grupo de pacientes com TEPT é, em média, 3,98 batimento por mimuto (bpm) (p=0,04) maior em comparação com aqueles sem o transtorno, e o coeficiente de correlação de Pearson combinado foi de 0,14 (p=0,05).Consistente com a hipótese levantada, a frequência cardíaca peritraumática de repouso foi maior em indivíduos que desenvolveram o TEPT. Contudo, mensuração mais próxima do evento traumático e a exclusão de casos dissociativos poderão ampliar a magnitude do efeito encontrado, tornando este biomarcador simples e facilmente obtido um preditor clinicamente útil do desenvolvimento de TEPT.

To characterise central neurons in the pedal ganglia of both male and female green lipped mussel, Perna canaliculus immunohistochemical techniques were used. Mollusc antibodies were used against neuropeptides and neurotansmitters known to control reproduction and spawning. Anti-ELH and anti-APGWamide showed very strong immunoreactivity in small type of neurons. Anti-5-HT and anti-DA immunoreactivity was mostly in large type of neurons. The labelled neurons are consistent with descriptions of neurosecretory cells implicated in the control of reproduction and spawning on the basis of earlier histological staining techniques used in this species. The use of selective immunological markers for peptides and amines appears to be a, promising tool for further characterisation of neurosecretory cells, and to isolate an'tl characterise neuropeptides and other biologically active materials involved in the control of reproduction in Perna canaliculus.
