Com a Política Nacional de Educação Especial na perspectiva da Educação Inclusiva (2008), as escolas regulares vêm recebendo um número maior de estudantes surdos ou com deficiência auditiva (S/DA), que antes frequentavam escolas especializadas. No entanto, dados apontam a diminuição do número de estudantes S/DA matriculados no ensino fundamental para o ensino médio, e do ensino médio para o ensino superior; ou seja, existem razões para se acreditar que barreiras educacionais se impõem no caminho desses estudantes para que conquistem uma formação educacional completa. Neste contexto, o objetivo deste trabalho é propor um modelo de aceitação de tecnologias levando em consideração fatores que envolvam aspectos do contexto da educação inclusiva, bem como efetuar experimento da interação de usuários S/DA com uma tecnologia para avaliar o modelo. Dentre os fatores mencionados um deles se refere às potenciais barreiras educacionais vivenciadas pelos estudantes S/DA em salas de aula inclusivas. Com relação à metodologia de pesquisa, o estudo desenvolveu-se em ciclos. Na medida em que as investigações avançavam, um novo estudo iniciava, se desenvolvia e se fechava. Isso permitiu que a proposta inicial tivesse sucessivos refinamentos ao longo do tempo até o ponto em que os questionamentos iniciais foram respondidos e o objetivo foi atingido. O modelo proposto mostrou resultados positivos, no sentido de conseguir capturar os fatores que podem influenciar a aceitação de tecnologias considerando o contexto de aplicação específico, uma vez que estes incorporam os aspectos da qualidade pragmática e os aspectos da qualidade hedônica, questões relacionadas à utilidade percebida da minimização de potenciais barreiras educacionais, expectativas futuras, e condições facilitadoras. Conclui-se que o modelo engloba tanto a investigação sobre questões motivacionais pessoais dos usuários quanto a investigação de aspectos do contexto de uso, e que o modelo pode ser utilizado para a finalidade a qual foi proposto, a avaliação de aceitação de tecnologias em ambientes de educação incluvisa. / With the foundation of the National Policy on Special Education on the Perspective of Inclusive Education (2008), mainstream schools are receiving a greater number of deaf or hard of hearing (D/HH) students, that once before were attending specialized schools. However, data point to the declining number of D/HH students enrolled from primary school to high school, and from high school students to higher education; ie, there are reasons to believe that educational barriers are imposed on the way of these students to conquer a complete education. In this context, the goal of this work is to propose a technology acceptance model that takes into account factors that ivolve aspects of the inclusive education context, as well as performing experiment on the interaction of D/HH users with a technology to evaluate the model. Among the factors, one of them refers to the potential educational barriers experienced by D/HH students in inclusive classrooms. With regard to research methodology, the study was developed in cycles. To the extent that the investigations progressed, a new study began, was unfolded and closed. This allowed successive refinements over time to the point where the initial questions were answered and the goal was reached. The proposed model has shown positive results in capturing factors that influence technology acceptance given the domain specific context, since they incorporate aspects of pragmatic quality and hedonic quality, also issues related to perceived usefulness in minimizing potential educational barriers, future expectations, and facilitating conditions. We conclude that the model encompasses both users personal motivation and context of use aspects, and the model can be used for the purpose for which it was proposed, technology acceptance evaluation considering inclusive education contexts.

In Fred Chappell’s Kirkman tetralogy, narrator Jess Kirkman synthesizes a multiplicity of perspectives for understanding the nature of truth. Blurring the distinction between art and life, Jess's narrative structure mirrors the imaginative reconstruction of experience; the novels are largely non-chronological emotive interactions with and reflections of his most salient memories and imaginings. Synthesizing an impressive cacophony of voices, Jess's stories both describe and apply the wisdom and tales Jess acquires from and with his family members. Each story informs the prior and the next, and the rhizomatic interaction between language, narrative, and reader explores Jess's numerous identities and understandings as narratives venture through space, time, and imagination.

<p>Syftet med denna uppsats är att utforska socialtjänstens arbete med brottsoffer i Sverige enligt 5 kapitlet 11 § i socialtjänstlagen. I studien undersöktes hur socialsekreterare definierar brottsoffer samt hur de bedömer och prioriterar offrens behov. Det har också varit centralt att studera hur socialsekreterare tolkar och förstår regleringen av socialtjänstens ansvar för brottsoffer. Kvalitativa intervjuer med 18 socialarbetare är grunden för studien. Analysen av socialtjänstens arbete med brottsoffer baseras på ovan nämnda intervjuer. Intervjuerna analyseras med hjälp av rättssociologiska teorier. För att illustrera hur socialsekreterare definierar brottsoffer har teorier om brottsoffer använts i analysen. Studien visar att ett brottsoffer måste vara oskyldig, svag och lida av brottet för att personen skall definieras som brottsoffer av socialsekreterarna. Socialsekreterarna har dock olika prioriteringar. Vissa socialsekreterare baserar sin bedömning efter varje enskilt fall, medan andra socialsekreterare anser att det är specifika målgrupper som ska få hjälp av socialtjänsten. Undersökningen visar också att de brottsoffergrupper som främst får hjälp inom socialtjänsten kvinnor och barn som fallit offer för våld i nära relationer. Stöd till brottsoffer som ges genom socialtjänstens arbete är ofta i syfte för att anpassa de kvinnor och barn som utsätts för våld, såsom kvinnojourer, rådgivning och ekonomiskt stöd.</p> / <p>The purpose of this essay is to explore the social services work with crime victims in Sweden, according to Chapter 5, § 11 of the Social Services Act. The study examined how social workers define the victim and assessing and prioritizing victims' needs. It has also been central to study how social workers interpret and understand the regulation of social services responsible for crime victims. Qualitative interviews with 18 social workers is the basis for the study. The analysis of the social services work with victims based in the above-mentioned interviews. The interviews analyzed using the sociology of law theory. To illustrate how social workers define victims of crime have theories of crime victims been used in the analysis.</p><p>The study shows that a crime victim must be innocent, weak and suffering from the crime to be defined as crime victims by social secretaries. Social workers do, however, different priorities. Some are based on an assessment of each individual victims need help, while others believe that the specific target groups will be using social services. The study also indicates that the groups which mainly receive help in the social services are victims of violence women and children. Assistance to victims in the social services designed to adapt the groups exposed to violence against women and children, such as women’s shelters, counseling and financial help.</p>

Chapter One will outline the way I will be using the constructs of "national" and "personal" identity, and will then move on to provide a brief contextual setting for the creation and importance of certain literary conventions of Irish topography and character, in particular by examining the cultural nationalism in Yeats's poems. In doing so, I will outline the metaphor of evolution which is crucial in this dissertation, and will examine some of the ethical implications of employing this metaphor. Chapter Two will examine the 1996 memoir Angela's Ashes by Frank McCourt, outline McCourt's employment of various stock Irish tropes, and show how this leads to a conflation of "personal" and "national" identity, to the detriment of the memoir. Chapter Three will turn to critique Are You Somebody?, the memoir by Nuala O'Faolain which was also published in 1996. I will argue that, in contrast to Angela 's Ashes, Are You Somebody? offers a constructive fusion of both kinds of identity national and personal. In Chapter Four, I will compare and contrast key issues in the texts, in relation to their both being memoirs of (Irish) national significance, published at the same time in a changing Ireland, and I will conclude by arguing that the process of invention which is necessary for the writing of a memoir is equally necessary for the creation of a national identity. / Thesis (M.A.)-University of Natal, Pietermaritzburg, 2001.

Denna studie syftar till att se på hur barn tar sig an konstruktionsritningar i jämförelse med fritt byggande i en lekfull gruppmiljö. Tidigare forskning visar skillnad mellan mängden män och kvinnor i tekniska yrken och även män och kvinnors inställning till de tekniska ämnena. Vissa forskare visar också på åldersskillnader mellan hur barn lär sig tekniska ämnen. Tar fyra- och femåringar frivilligt sig an konstruktionsritningar, följer dem och färdigställer de konstruktionen? Studien har särskilt tittat på om det fanns skillnader mellan flickorna och pojkarna när de byggde? Hur påverkar barnens eget intresse hur de bygger? Om barn, fyra och fem år gamla kan följa bygginstruktioner? Resultatet av denna studie, i viss mån, stödjer tidigare forskning om att det finns en genus aspekt redan i förskoleåldern, pojkarna var mer försekomna och hade lättare för att följa lego instruktioner än flickorna, men frågan kvarstår; varför finns denna skillnad? Förutom genusaspekten fanns det också ett tydligt resultat som visade på skillnad i byggkunskap mellan fyraåringar och femåringar. Fyraåringarna utforskade främst byggmaterialet, medan många av femåringarna kunde följa en Legobygginstruktion näst intill perfekt. / This study aims to look at how children approach building instructions compared to free building in a playful group environment. Researchers have found age differences, between how young children learn technical subjects. Other studies show that there are differences between the number of men and women in technical professions and also between men and women’s approach to the technical subjects. This study seeks discover if and how four and five year olds voluntarily use, follow, and complete a building exercise using instructional drawings. The study paid close attention to if girls and boys had different approaches to building; how does the children’s own interests affect the process of building? If children aged four and five years are capable of following building instructions. The results of this study to some extent support earlier research that there is a gender difference already at four to five years of age, but the question still remains why this difference exists. As well as the gender difference, there was also a strong result showing a difference in building knowledge between the four year olds and the five year olds. The four year olds mainly explored the building material whereas many of the five year olds could successfully follow the building instructions.

This PhD aimed to elucidate the mechanisms by which polymorphisms may alter androgen-induced transactivation of androgen receptor (AR) target genes which may be important in prostate cancer aetiology. The second aspect of this PhD focused on identifying and characterising functional polymorphisms that may have utility as predictive risk indicators for prostate cancer and which may aid in earlier therapeutic intervention and better disease management. Analyses were carried out on the kallikrein-related peptidase 3 (KLK3), also known as the prostate specific antigen (PSA), gene and the kallikrein-related peptidase 4 (KLK4) gene. The PSA and KLK4 genes are part of the serine protease family that have trypsin or chymotrypsin like activity and are thought to play a role in the development of hormone-dependent cancers in tissues such as those in the prostate, breast, endometrium and ovaries. In the prostate, PSA is regulated by androgens and three androgen response elements (AREs) have been described in the promoter and upstream enhancer region. The PSA ARE I harbours a polymorphism at -158 bp from the transcription initiation site (TIS) that results in a G to A transition (G-158A). This PhD investigated the functional significance of the PSA G-158A polymorphism which has been reported to be associated with prostate cancer risk. Electromobility shift assays (EMSAs) investigating the interaction of ARE I variants with the AR DNA binding domain (AR-DBD) demonstrated that the A allele had a two-fold increased binding affinity for the AR-DBD when compared with the G allele. This was confirmed with endogenous AR in limited proteolysis-EMSA experiments. The limited proteolysis-EMSA experiments also demonstrated differential sensitivities of PSA ARE I alleles to trypsin digestion, which suggests that the G-158A polymorphism has an allosteric effect on the AR that alters AR/ARE I complex stability. Furthermore, Chromatin Immunoprecipitation (ChIP) assays suggest that the A allele more readily recruited the AR in vivo when compared with the G allele and is consistent with the in vitro binding data. Luciferase reporter assays carried out in both LNCaP and 22Rv1 prostate cancer cells, and using the natural (dihydrotestosterone; DHT) ligand demonstrated that the A allele was more responsive to androgens in LNCaP cells. Hence, this study has elucidated the potential mechanisms by which the G-158A polymorphism may differentially regulate PSA expression (of which up-regulation of PSA is thought to be important in prostate cancer development and progression). KLK4 has similar tissue-restricted expression as PSA and is up-regulated by steroid hormones in many endocrine cells including those in the prostate. A putative ARE (KLK4-pARE) located at -1,005 to -1019 relative to the more predominantly used transcription initiation site, TIS3, was initially found in supershift assays using AR antibodies to interact with endogenous AR. However, subsequent EMSA analysis using purified AR-DBD suggest that KLK4-pARE may be interacting with the AR indirectly. To investigate this hypothesis, a tandem construct of KLK4-pARE was cloned into the pGL3-Promoter vector for hormone-induced reporter assays. However, reporter assays did not demonstrate any responsiveness of KLK4-pARE to androgens, estradiol or progestins. Consequently, Real-Time PCR was carried out to reassess the hormonal regulation of KLK4 at the mRNA level. Consistent with the literature, data from this study suggests that KLK4 may be up-regulated by androgens, progestins and estradiol in a cyclical manner. Hormone-induced luciferase reporter assays were then carried out on seven promoter constructs that span 2.8 kb of the KLK4 promoter from TIS3. However, none of the seven promoter constructs demonstrated any significant responsiveness to androgens, estradiol or progestins. This study suggests that hormone response elements (HREs) that may drive the hormonal regulation of KLK4 in prostate cancer may be located further upstream from the promoter region investigated in this PhD, or alternatively, may lie 3' of TIS3. The characterisation of KLK4 promoter polymorphisms and their flanking sequences were also carried out in parallel to the functional work with the intent to assess the functional significance of any polymorphisms that may be located within HREs. In total 19 polymorphisms were identified from the public databases and from direct sequencing within 2.8 kb of the KLK4 promoter from TIS3. However, the functional and clinical significance of these 19 polymorphisms were not further pursued given the negative findings from the functional work. The PSA AR enhancer region was also assessed for potential polymorphisms that may be associated with prostate cancer risk. A total of 12 polymorphisms were identified in the PSA enhancer of which two (A-4643G and T-5412C) have been reported to alter functionality of the enhancer region and thus, prioritised for further analysis. Association analysis for prostate cancer risk was then carried out on these PSA enhancer polymorphisms as none of the KLK4 promoter polymorphisms were found in functional HREs. No significant association for either the A-4643G or T-5412C polymorphism with prostate cancer risk was found at the P = 0.05 level. However, under an age-adjusted dominant model a 1.22- (95% CI = 1.16-1.26) and 1.23-fold (95% CI = 1.17-1.29) increased risk for prostate cancer was found for the A-4643G or T-5412C polymorphisms, respectively. Both polymorphisms were also assessed for association with tumour grade and stage and PSA levels. Genotypes were significantly different for the A-4643G and T-5412C polymorphisms with tumour stage and PSA levels, respectively. However, these results are likely to be biased by the case population which consist primarily of men who presented with incidental (pT1) and organ-confined (pT2) tumours. To summarise, the A-4643G and T-5412C polymorphisms are unlikely to be associated with prostate cancer risk, PSA levels or stage/grade of disease. However, further analyses in a larger cohort is warranted given that these polymorphisms alter androgen responsiveness of the PSA enhancer and that elevated PSA levels are indicative of men with prostate cancer. To summarise, this PhD has elucidated the functional significance of the PSA G-158A polymorphism in prostate cancer and which may be important in prostate cancer patho-physiology. This PhD has also furthered the understanding of the hormonal regulation of KLK4 in prostate cancer cells. Finally, this PhD has carried out a pilot study on two functional PSA enhancer polymorphisms (A-4643G and T-5412C) with prostate cancer risk.

The aim of this study is to use an intermedial theory to analyse and contextualize embodiment and violence in the Chinese author Mo Yan’s Life and Death Are Wearing Me Out. I use Jørgen Bruhn’s mediality model, introduced in The Intermediality of Narrative Literature: Medialities Matter (2016), to analyse medial phenomena such as intra- and intermediality in the novel. Bruhn’s model mainly covers relations between several media and within a single medium. The focus of this study lies on the blending of different media within the novel. My hypothesis is that the depiction of embodied violence in the novel is a literary strategy, based on cognitive functions and Chinese oral traditions to communicate historical events, as well as through an intermedial depiction of those events, a way to avoid censorship. Of particular importance to this study are medial phenomena connected to visualization of memories, and intermediality as discipline a voice between media texts, to establish how a literary text through narrative techniques can create an illusion of cinematic blending. I see this as an illustration of the historical hierarchical struggle between art forms. This is a broader perspective on literary depiction in Mo Yan’s novel than generally can be found in interpretations originating in a Western discourse. The result of my study shows that medial phenomena such as inter- and intramediality are woven into a narrative theme of remembrance of historical political events. Such memories are communicated through depictions of embodied violence, as well as the impact of trauma on anonymous bodies reminiscent of cinematic techniques, heightened by the metafictive voice of Mo Yan within the novel. It is a perspective that is also accentuated through auditory and visual elements that recall the ability of audio-visual media techniques to create identification with exposed bodies through close-up depictions of body and violence. Hence, Mo Yan has constructed a grid of medial phenomena in the novel through which he is able to convey historical processes without risking censorship.

La formation de nouveaux vaisseaux sanguins ou angiogenèse soutient la croissance tumorale en fournissant l'oxygène et les nutriments qui lui sont nécessaires. Le rôle clé du facteur de croissance de l'endothélium vasculaire VEGF dans ce processus a suscité le développement de stratégies anti-angiogéniques pour le traitement du cancer. Cependant, des travaux précliniques et des données cliniques suggèrent l'émergence de résistances aux anti-angiogéniques, en raison notamment de la redondance des facteurs de croissance pro-angiogéniques. Il est donc nécessaire de développer des stratégies alternatives plus efficaces. En 2010, notre laboratoire a apporté la preuve de concept d'une thérapie anti-tumorale et anti-angiogénique innovante basée la dégradation des ARNm à demi-vie courte par la protéine à doigts de zinc TIS11b. Néanmoins, l'instabilité de la protéine thérapeutique a entravé la caractérisation plus détaillée de cette stratégie. Dans ce contexte, l'objectif majeur de ma thèse était l'optimisation de la stabilité et de l'activité de TIS11b et l'évaluation de son efficacité thérapeutique. Pour cela, nous avons généré une nouvelle protéine TIS11b génétiquement modifiée sur la base d'études biochimiques et moléculaires. Notamment, nous avons observé que la phosphorylation de la sérine 334 située dans le domaine C-terminal de TIS11b augmente de façon très significative la stabilité de la protéine et potentialise son activité déstabilisatrice de l'ARNm du VEGF. De plus, la délétion du domaine N-terminal augmente également la stabilité de TIS11b sans altérer son activité. Nous avons alors généré deux nouvelles protéines thérapeutiques, la protéine ZnC et la protéine ZnC334D pour laquelle la troncation du domaine N-terminal et la substitution de la sérine S334 par un aspartate mimant une phosphorylation ont été combinées. Les nouvelles protéines ont été fusionnées à une étiquette polyarginine R9 leur permettant de traverser les membranes cellulaires (R9-ZnC et R9-ZnCS334D). Nous avons montré que R9-ZnC et R9-ZnCS334D inhibent l'expression de VEGF in vitro dans la lignée de cancer du sein murin 4T1. De plus, R9-ZnCS334D exerce une activité anti-proliférative, anti-migratoire et anti-invasive dans ces cellules. In vivo, l'injection intra-tumorale de R9-ZnCS334D dans des tumeurs 4T1 préétablies inhibe significativement l'expression du VEGF, la croissance et la vascularisation tumorales. De façon remarquable, l'analyse des extraits tumoraux indique que le traitement diminue l'expression de chimiokines clés dans les processus d'angiogenèse, d'inflammation et d'invasion (Fractalkine, MCP-1, NOV, SDF-1, Pentraxin…). Enfin, R9-ZnC et R9-ZnCS334D inhibent l'expression de marqueurs de la transition épithélio-mésenchymateuse, un processus impliqué dans la dissémination métastatique. L'ensemble de ces travaux indique que R9-ZnC et R9-ZnCS334D sont des molécules anti-tumorales multi-cibles, qui inhibent plusieurs étapes clés de la progression tumorale. Cette étude confirme que le ciblage de la stabilité des ARNm est une stratégie prometteuse et novatrice pour le développement de nouvelles thérapies anti-cancéreuses. / One of the innovative aspects of anti-cancer therapies is the possibility of preventing tumor growth by blocking blood supply. Cancer cells induce the formation of their own blood vessels from pre-existing vasculature, a process called angiogenesis. One of the most important proangiogenic factors is vascular endothelial growth factor (VEGF). The success of bevacizumab (a humanized anti-VEGF monoclonal antibody) combined to chemotherapy for the treatment of human metastatic cancers has validated VEGF as an efficient target. However, despite the initial enthusiasm, resistance to these anti-angiogenic treatments resulting from compensatory mechanisms occurs upon time. For this reason, there is a real need for new anti-angiogenic drugs that will target the angiogenic process through distinct mechanisms. In 2010, our laboratory has successfully developed an anti-angiogenic and anti-tumoral therapy based on destabilization of short-lived mRNAs by the zinc finger protein TIS11b. However, the therapeutic protein was highly unstable, thus making it difficult to further characterize the experimental therapy. In this context, the main task of my thesis was the optimization of TIS11b stability and activity followed by the evaluation of the multi-target action of our novel protein on tumor development. In a first part of this work, biochemical and molecular approaches allowed us to demonstrate that phosphorylation of the C-terminal serine S334 in TIS11b protein markedly increases its stability. In addition, deletion of the N-terminal domain of TIS11b highly increases its protein stability without affecting its activity. Therefore, we integrated N-terminal truncation (ZnC) and C-terminal substitution of S334 by an aspartate to mimic a permanent phosphorylation at S334 (ZnCS334D) as a novel TIS11b engineering strategy. Both proteins were fused subsequently to a cell-penetrating peptide polyarginine (R9). In vitro studies revealed that R9-ZnC and R9-ZnCS334D inhibit VEGF expression in the murine breast cancer cells 4T1. In addition, R9-ZnCS334D impaired proliferation, migration, invasion and anchorage-independent growth of 4T1 cells. In vivo, intra-tumoral injection of either protein significantly reduced VEGF expression and tumor vascularization. Strikingly, antibody array analyses of tumor extracts demonstrated a reduced expression of several chemokines such as Fractalkine, MCP-1, NOV, SDF-1 and Pentraxin upon R9-ZnC or R9-ZnCS334D treatment. These factors, which are produced by several cell types within tumor tissue, are key drivers of tumor angiogenesis, tumor-promoting inflammation and invasion. Furthermore, the expression of markers of the epithelial-to-mesenchymal transition was also significantly reduced, suggesting an anti-metastatic effect of R9-ZnC and R9-ZnCS334D. Thus, we provide R9-ZnC and R9-ZnCS334D as potential novel multi-target agents which inhibit key hallmarks of cancer progression. This work supports the emerging link between mRNA stability and cancer and proposes novel concepts for the development of innovative anti-cancer therapies.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / “The constitution of the narrative and figural self in the complex temporality of Lobo Antunes” has as study object the novel What horses are those that make shade on the sea? (2009), by the contemporary Portuguese writer Antonio Lobo Antunes. In the novel it is narrated the story of the affective de-structure and the loss of the material goods of a traditional Portuguese family, through the voices of family‟s components. It is confused in the narrative, thus, the past experiences of the characters and their projections for the future. The characters-narrators, when remembering the past experiences and when projecting expectations for the future, defocus the present of the narrative in reflections that seem not to finish any conclusion about their experiences. It results from that a chaotic and bitter world, marked by multiple and contradicted affections of the characters in relation to their relatives, manifesting in the own structure of the narrative, with its ramifications, deviances and fragmentations. The configuration of the intrigue ends to evince, then, the conflicting and problematic nature of the own characters. This incessant returning to the past allied to this expectative of future and the reflections about the events reconstruct these distinct moments of experience of time in a present time always distended, in transition. The novel seems to reconstruct certain aporia of time, once that the time shows itself as makeable in the consciousness of the characters, and paradoxically, as fluid and transitory. This thick and complex character of temporality in the narrative configuration, the intertwine among told present, remembered past and expected future confers a psychological density to the characters, and never attributing to them an stable and cohesive identity and an integral image. We find, thus, in this dissertation, a reflection about the contemporary Portuguese literature, the work of the author, and an analysis of the novel based, mainly, on the studies of Paul Ricoeur about the interdependence among the configuration of intrigue, temporality and the constitution of a narrative identity. / “A constituição do eu narrativo e figural na temporalidade complexa de Lobo Antunes” tem como objeto de estudo o romance Que cavalos são aqueles que fazem sombra no mar? (2009), do escritor português contemporâneo António Lobo Antunes. No romance, é narrada a história de desestruturação afetiva e de perda dos bens materiais de uma tradicional família portuguesa, através das vozes dos componentes dessa família. Confundem-se na narrativa, então, as vivências passadas das personagens e as suas projeções para o futuro. As personagens-narradoras, ao relembrar as experiências do passado e ao projetar expectativas para o futuro, desfocam o presente da narrativa em reflexões que parecem não encerrar conclusão alguma sobre suas vivências. Resulta disso um mundo caótico e amargo, marcado pelos múltiplos e contraditórios afetos das personagens em relação aos seus familiares, manifestado na própria estrutura da narrativa, com suas ramificações, desvios e fragmentações. A configuração da intriga acaba por evidenciar, então, o caráter conflitante, problemático das próprias personagens. Esse retorno incessante ao passado aliado a essa expectativa do futuro e às reflexões sobre os eventos reconstroem esses momentos distintos da experiência do tempo em um tempo presente sempre distendido, em transição. O romance parece reconstituir certa aporia do tempo, visto que os tempos mostram-se como marcantes na consciência das personagens e, paradoxalmente, como fluidos e transitórios. Esse caráter denso e complexo da temporalidade na configuração da narrativa, o entrelaçamento entre presente contado, passado relembrado e de um futuro esperado confere uma densidade psicológica às personagens, sem nunca atribuir-lhes uma identidade estável e coesa e uma imagem íntegra. Encontra-se nessa dissertação, uma reflexão sobre a literatura portuguesa contemporânea, a obra do autor, e uma análise do romance com base, principalmente, nos estudos de Paul Ricoeur sobre a interdependência entre a configuração da intriga, a temporalidade e a constituição de uma identidade narrativa.
