El propósito de este artículo consiste en explorar los mecanismos y representaciones de lo siniestro en "La hija de Rappacci" de Nathaniel Hawthome como expresión del mal dentro de los límites del género gótico del siglo XIX; como expresión del tema del doble en tres personajes humanos y en uno no humano que aparecen en el cuento; y como expresión de trasgresión en el personaje principal, Giovanni Guasconte. El concepto de lo siniestro que se usará será el de la teoría psicoanalítica, siguiendo especialmente los aportes de Sigmund Freud y Jacques Lacan. The purpose of this artide is to explore the mechanisms and representations of the uncanny in Nathaniel Hawthome's "Rappaccini's Daughter" as an expression of evil within nineteenth century Gothic boundaries; as an expression of the theme of the double in three human characters and in one non-human component of Rappaccini's garden; and as an expression of transgression in Giovanni Guasconte, the main character. The concept of the uncanny to be used will be that of psychoanalytic theory, especially reliant on the contributions on the topic by Sigmund Freud and Jacques Lacan.

The purpose of this dissertation is to study literary representations of Eastern Europe in the works of celebrated and less-known American authors, who visited and narrated the region between the mid-1960s and early 2000s. The main critical body focuses on Eastern Europe before 1989 and encompasses three major voices of American literature: John Updike, Joyce Carol Oates, and Philip Roth. However, in the last chapter I also explore American literary perceptions of the area following the collapse of communism. Importantly, the term “Eastern Europe” as used in this dissertation is charged with significance. I approach it not only as a space on the map or the geopolitical construct which emerged in the aftermath of the Second World War, but rather as a conceptual category and a repository of meanings built out of fact and fantasy: specific historical, political and cultural realities interlaced with subjective worldviews, preconceptions, and mental images. The critical framework of this dissertation is twofold. I reach for the concept of liminality to elucidate the indeterminacy and malleability which lies at the heart of the object of study—the idea, image, and experience of Eastern Europe. Bearing in mind the nature of the works under analysis, all of which were inspired by actual visits behind the Iron Curtain, I propose to interpret these transatlantic literary journeys in terms of generative experience, where Eastern Europe is mapped as a liminal space of possibility; a contact zone between cultures and, potentially, the locus of self-discovery and individual transformation. If liminality is the metaphor or a lens that I employ in order to account for the nature of the analyzed works and the complex terrain they map, imagology, whose purpose is to study the processes of constructing selfhood and otherness in literature, provides me with the method and the critical vocabulary for analyzing selected literary representations. The dissertation is divided into six chapters, the last of which serves as coda to the previous discussion. The first two chapters constitute the critical foundation of this work. Then, in chapters 3, 4, and 5 I study American images of Eastern Europe in the works written by John Updike, Joyce Carol Oates, and Philip Roth, respectively. The last, sixth chapter of this dissertation is divided into two parts. In the first one, I discuss new critical perspectives and avenues of research in the study of Eastern Europe following the collapse of communism. Then, I carry out a joint analysis of four works written after 1989 by Eva Hoffman, Arthur Phillips, John Beckman, and Gary Shteyngart. The dissertation ends with conclusions in which I summarize my findings and reflections, and suggest implications for future research. As this dissertation seeks to demonstrate, Eastern Europe portrayed in the analyzed works oscillates between contradictory representations which are contingent upon a number of factors, most importantly who maps it and in what context. Even though each experience of Eastern Europe is distinct and fueled by the profiles, identities, and interests of the characters and their creators, I have found out that certain patterns of othering are present in all the works. Thus, my research seems to suggest that there is something of a recurrent literary image of Eastern Europe, which goes beyond the context of the Cold War. Accordingly, while this dissertation hopes to be a valid contribution to the study of literary and cultural mappings of Eastern Europe, it also generates new questions regarding the current, post-communist representation of the area and its relationship to the national tropes explored in my work.

The thermoset epoxy resin EPON 862, coupled with the DETDA hardening agent, are utilized as the polymer matrix component in many graphite (carbon fiber) composites. Because it is difficult to experimentally characterize the interfacial region, computational molecular modeling is a necessary tool for understanding the influence of the interfacial molecular structure on bulk-level material properties. The purpose of this research is to investigate the many possible variables that may influence the interfacial structure and the effect they will have on the mechanical behavior of the bulk level composite. Molecular models are established for EPON 862-DETDA polymer in the presence of a graphite surface. Material characteristics such as polymer mass-density, residual stresses, and molecular potential energy are investigated near the polymer/fiber interface. Because the exact degree of crosslinking in these thermoset systems is not known, many different crosslink densities (degrees of curing) are investigated. It is determined that a region exists near the carbon fiber surface in which the polymer mass density is different than that of the bulk mass density. These surface effects extend ~10 Å into the polymer from the center of the outermost graphite layer. Early simulations predict polymer residual stress levels to be higher near the graphite surface. It is also seen that the molecular potential energy in polymer atoms decreases with increasing crosslink density. New models are then established in order to investigate the interface between EPON 862-DETDA polymer and graphene nanoplatelets (GNPs) of various atomic thicknesses. Mechanical properties are extracted from the models using Molecular Dynamics techniques. These properties are then implemented into micromechanics software that utilizes the generalized method of cells to create representations of macro-scale composites. Micromechanics models are created representing GNP doped epoxy with varying number of graphene layers and interfacial polymer crosslink densities. The initial micromechanics results for the GNP doped epoxy are then taken to represent the matrix component and are re-run through the micromechanics software with the addition of a carbon fiber to simulate a GNP doped epoxy/carbon fiber composite. Micromechanics results agree well with experimental data, and indicate GNPs of 1 to 2 atomic layers to be highly favorable. The effect of oxygen bonded to the surface of the GNPs is lastly investigated. Molecular Models are created for systems with varying graphene atomic thickness, along with different amounts of oxygen species attached to them. Models are created for graphene containing hydroxyl groups only, epoxide groups only, and a combination of epoxide and hydroxyl groups. Results show models of oxidized graphene to decrease in both tensile and shear modulus. Attaching only epoxide groups gives the best results for mechanical properties, though pristine graphene is still favored.

On the night of April 20, 2010, a group of students from the University of Puerto Rico (UPR), Río Piedras campus, met to organize an indefinite strike that quickly broadened into a defense of accessible public higher education of excellence as a fundamental right and not a privilege. Although the history of student activism in the UPR can be traced back to the early 1900s, the 2010-2011 strike will be remembered for the student activists’ use of new media technologies as resources that rapidly prompted and aided the numerous protests. ^ This activist research entailed a critical ethnography and a critical discourse analysis (CDA) of traditional and alternative media coverage and treatment during the 2010 -2011 UPR student strike. I examined the use of the 2010-2011 UPR student activists’ resistance performances in constructing local, corporeal, and virtual spaces of resistance and contention during their movement. In particular, I analyzed the different tactics and strategies of resistance or repertoire of collective actions that student activists used (e.g. new media technologies) to frame their collective identities via alternative news media’s (re)presentation of the strike, while juxtaposing the university administration’s counter-resistance performances in counter-framing the student activists’ collective identity via traditional news media representations of the strike. I illustrated how both traditional and alternative media (re)presentations of student activism developed, maintained, and/or modified students activists’ collective identities. ^ As such, the UPR student activism’s success should not be measured by the sum of demands granted, but by the sense of community achieved and the establishment of networks that continue to create resistance and change. These networks add to the debate surrounding Internet activism and its impact on student activism. Ultimately, the results of this study highlight the important role student movements have had in challenging different types of government policies and raising awareness of the importance of an accessible public higher education of excellence.^

We compute the E-polynomials of the moduli spaces of representations of the fundamental group of a complex curve of genus g = 3 into SL(2, C), and also of the moduli space of twisted representations. The case of genus g = 1, 2 has already been done in [12]. We follow the geometric technique introduced in [12], based on stratifying the space of representations, and on the analysis of the behaviour of the E-polynomial under fibrations.

It is a widely acknowledged and often unquestioned fact that patriarchy and its modes of behaviour and social organization favour the appearance of trauma on the weakest (and defenceless) members of society: women. In the last decades, trauma seems to have taken the baton of typically female maladies such as 19th c. hysteria or 20th c. madness. Feminists in the 20th c. have long worked to prove the connection between the latter affections (and their reflection in literary texts) and patriarchal oppression or expectations of feminine behaviour and accordance to roles and rules. With Trauma Studies on the rise, the approach to the idea of the untold as related to femininity is manifold: on the one hand, is not trauma, which precludes telling about one’s own experience and keeps it locked not only from the others, but also from ourselves, the ultimate secrecy? On the other hand, when analyzing works that reflect trauma, one is astounded by the high number of them with a female protagonist and an almost all-female cast: in this sense, a ‘feminist’ reading is almost compulsory, in the sense that it is usually the author’s assumption that patriarchal systems of exploitation and expectations favour traumatic events and their outcome (silence and secrets) on the powerless, usually women. Often, traumatic texts combine feminism with other analytical discourses (one of the topics proposed for this panel): Toni Morrison’s study of traumatic responses in The Bluest Eye and Beloved cannot be untangled from her critique of slavery; just as much of Chicana feminism and its representations of rape and abuse (two main agents of trauma) analyze the nexus of patriarchy, new forms of post-colonialism, and the dynamics of power and powerlessness in ethnic contexts. Within this tradition that establishes the secrecies of trauma as an almost exclusively feminine characteristic, one is however faced with texts which have traumatized males as protagonists: curiously enough, most of these characters have suffered trauma through a typically masculine experience: that of war and its aftermath. By analyzing novels dealing with war veterans from Vietnam or the Second World War, the astounding findings are the frequent mixture of masculine or even ‘macho’ values and the denial of any kind of ‘feminine’ characteristics, combined with a very strict set of rules of power and hierarchy that clearly establish who is empowered and who is powerless. It is our argument that this replication of patriarchal modes of domination, which place the lowest ranks of the army in a ‘feminine’ situation, blended with the compulsory ‘macho’ stance soldiers are forced to adopt as army men (as seen, for example, in Philip Caputo’s Indian Country, Larry Heinemann’s Paco’s Story or Ed Dodge’s DAU: A Novel of Vietnam) furthers the onset and seriousness of ulterior trauma. In this sense, we can also analyze this kind of writing from a ‘feminist’ point of view, since the dynamics of über-patriarchal power established at the front at war-time deny any display of elements traditionally viewed as ‘feminine’ (such as grief, guilt or emotions) in soldiers. If trauma is the result of a game of patriarchal empowerment, how can feminist works, not only theoretical, but also fictional, overthrow it? Are ‘feminine’ characteristics necessary to escape trauma, even in male victims? How can feminist readings of trauma enhance our understanding of its dynamics and help produce new modes of interaction that transcend power and gender division as the basis for the organization of society?

A radical change took place in Mexican narratives of belonging during the 1990s, when NAFTA was first negotiated. Narratives of migration drastically changed the status of Mexican migrants to the US, formerly derided as ‘pochos’, presenting them as model citizens instead. Following Derrida, I argue the role of the migrant became that of a supplement, which is, discursively, at the same time external to and part of a given unit, standing for and allowing deeper transformations to take place in the whole discourse of bilateral relations and national identity more generally. I use Derrida’s concept of the supplement to discuss changing representations of Chicanos in Mexican cinema, and to assess the extent that they have succeeded in reframing the discourse on national identity, with a focus on gender.

Humans’ perceived relationship to nature and non-human lifeforms is fundamental for sustainable development; different framings of nature – as commodity, as threat, as sacred etc. – imply different responses to future challenges. The body of research on nature repre-sentations in various symbolic contexts is growing, but the ways in which nature is framed by people in the everyday has received scant attention. This paper aims to contribute to our understanding of the framing of nature by studying how wild-boar hunting is depicted on YouTube. The qualitative frame analysis identified three interrelated frames depicting hunting as battle, as consumption, and as privilege, all of which constitute and are constituted by the underlying notion of human as superior to nature. It is suggested that these hegemonic nature frames suppress more constructive ways of framing the human-nature relationship, but also that the identification of such potential counter-hegemonic frames enables their discursive manifestation.

This article presents an analysis of identity and representations of black women in the tales Keep Secret Esmeralda Ribeiro, Rosa and Fusilier and Voices d'Rachel de Queiroz Africa. The story of Esmeralda Ribeiro black author, published in Cadernos Negros: the best short stories (1998) reexamines Clara dos Anjos, Lima Barreto's novel character written between 1904 and 1922. In this work, the author lays bare, in a confessional tone, the daily life of Rio suburbs, from the perspective of racial prejudice, and is the protagonist as a passive woman, submissive, an object. Emerald, black writer, gives Clara a condition of the subject, building an identity as a woman and as a black. It is the chronicle of belonging. Rosa and the Marine and Voices of Africa Rose protagonist appointing chronic-tale first is the outcome of its history in the second text, both published in the first Rachel de Queiroz of chronic compilation entitled The Maiden and Moura Pie (1948 ). Rachel is the text representation of black women because they can not as white women have the lived experience as black to build identity and can do it in generalizing way considering his wife condition and his experience in the feminine universe. There are relations between the texts that go beyond the theme, Space Rio suburb and similarities between Rosa and Clara, Cassi and the Marines. You can see the works a dialogue between sex and race interests, identities and stereotypes, relationships that materialize in Literature.

This study has the objective of analyzing, based on the theoretical and methodological device of the French Discourse Analysis, the meanings that (are) produce(d) (in) the photographs that compose the special report entitled “Cidades médias” (“Medium-sized cities”), published by Veja magazine in September, 2010. This report aims, according to the magazine, at highlighting which are the Brazilian cities that are considered “metropolis of the future”, for making possible, amongst other elements, also the obtainment of financial success. If the photographs in the media act as supports of the linguistic materiality, as representations of reality, I intend in this study: work with the effect of evidence produced by the photograph; reflect about the ideological crossing, which determines what can and must be said and, therefore, what cannot and must not be said; analyze in what way this crossing passes by the image and what is its representation in the journalistic discourse; and analyze which are the meanings produced by the photographs that compose the special report on Veja magazine; also in their relation to the subjects introduced there. For my investigation, I was based on the contributions of Barthes (1984) and Dubois (1993) and in some important concepts for the Discourse Analysis field found in Pêcheux (2009 [1988]) and Orlandi (2007 [1992]; 1995).

Teachers, as professionals, carry out an essential role in the process of the social change. For this purpose, the process of teachers’ formation are deserving highlighted in the research field of Applied Linguistics, aiming to enhance the work of language professionals. In this term, the current paper seeks to investigate the previous knowledge of the students of Letters Course at Unioeste, subjects of this study, about teaching career and professor’s identity constitution.  Simultaneously, it is discussed some implications between the educational trajectory and these students’ Professional choice, considering that it is found in the initial stage of this formative process. The adopted methodology consists of a qualitative approach from memorials, seeking to stand out the conceptions and representations of those subjects about constitution of the teacher. Among some characteristics that stand out in the narratives regarding teacher identity, are the complexity of teaching, like the profession, as well as the diverse teaching practices and 'transgressive'.

This project utilises creative practice as research, and involves writing and discussing four sample episodes of a proposed six-part dramatic, black-comedy1 television mini-series titled The New Lows. Combined, the creative project and accompanying exegesis seeks to illuminate and interrogate some of the inherent concerns, pitfalls and politics encountered in writing original Asian-Australian characters for television. Moreover, this thesis seeks to develop and deliberate on characters that would expand, shift and extend concepts of stereotyping and authenticity as they are used in creative writing for television. The protagonists of The New Lows are the contemporary and dysfunctional Asian-Australian Lo family: the Hong Kong immigrants John and Dorothy, and their Australian-born children Wendy, Simon and Tommy. Collectively, they struggle to manage the family business: a decaying suburban Chinese restaurant called Sunny Days, which is stumbling towards imminent commercial death. At the same time, each of the characters must negotiate their own personal catastrophes, which they hide from fellow family members out of shame and fear. Although there is a narrative arc to the series, I have also endeavoured to write each episode as a selfcontained story. Written alongside the creative works is an exegetical component. Through the paradigm of Asian-Australian studies, the exegesis examines the writing process and narrative content of The New Lows, alongside previous representations of Asians on Australian and international television and screen. Concepts discussed include stereotype, ethnicity, otherness, hybridity and authenticity. However, the exegesis also seeks to question the dominant cultural paradigms through which these issues are predominantly discussed. These investigations are particularly relevant, since The New Lows draws upon a suite of characters commonly considered to be stereotypical in Asian-Australian representations.

This paper examines performances that defy established representations of disease, deformity and bodily difference. Historically, the ‘deformed’ body has been cast – onstage and in sideshows – as flawed, an object of pity, or an example of the human capacity to overcome. Such representations define the boundaries of the ‘normal’ body by displaying its Other. They bracket the ‘abnormal’ body off as an example of deviance from the ‘norm’, thus, paradoxically, decreasing the social and symbolic visibility (and agency) of disabled people. Yet, in contemporary theory and culture, these representations are reappropriated – by disabled artists, certainly, but also as what Carrie Sandahl has called a ‘master trope’ for representing a range of bodily differences. In this paper, I investigate this phenomenon. I analyse French Canadian choreographer Marie Chouinard’s bODY rEMIX/gOLDBERG vARIATIONS, in which 10 able-bodied dancers are reborn as bizarre biotechnical mutants via the use of crutches, walkers, ballet shoes and barres as prosthetic pseudo-organs. These bodies defy boundaries, defy expectations, develop new modes of expression, and celebrate bodily difference. The self-inflicted pain dancers experience during training is cast as a ‘disablement’ that is ultimately ‘enabling’. I ask what effect encountering able bodies celebrating ‘dis’ or ‘diff’ ability has on audiences. Do we see the emergence of a once-repressed Other, no longer silenced, censored or negated? Or does using ‘disability’ to express the dancers’ difference and self-determination usurp a ‘trope’ by which disabled people themselves might speak back to the dominant culture, creating further censorship?

Field experiences for young children are an ideal medium for environmental education/education for sustainability because of opportunities for direct experience in nature, integrated learning, and high community involvement. This research documented the development - in 4-5 year old Prep children - of knowledge, attitudes and actions/advocacy in support of an endangered native Australian animal, the Greater Bilby. Data indicated that children gained new knowledge, changed attitudes and built a repertoire of action/ advocacy strategies in native animal conservation as a result of participating in a forest field adventure. The curriculum and pedagogical features that supported these young children’s learning include: active engagement in a natural environment, learning through curriculum integration at home and at school, anthropomorphic representations of natural elements, making connections with cultural practices, and intergenerational learning. The paper also highlights research strategies that can be usefully and ethically applied when conducting studies involving young children.
