Esses filmes fizeram um grande sucesso frente ao p?blico brasileiro, mas sempre eram ridicularizados pela cr?tica que os julgava como cinema mal realizado. Nesse contexto, parte dessa produ??o cinematogr?fica pode ser classificada como par?dia. Considerando isso, este trabalho, cujo tema ? linguagem e cinema, tem como objeto de investiga??o a constru??o do discurso par?dico e a cosmovis?o carnavalesca na pornochanchada e se insere na ?rea da Lingu?stica Aplicada de perspectiva s?cio-hist?rica. Para realizamos a an?lise, detemo-nos na investiga??o dos elementos verbo-visuais presentes na forma composicional de tr?s com?dias er?ticas produzidas na d?cada de 70 como tamb?m analisamos o projeto de dizer constituidor/constituinte da forma arquitet?nica. Como fundamento te?rico-metodol?gico priorit?rio, baseamo-nos nas formula??es sobre linguagem advindas do C?rculo de Bakhtin (2006, 2010), tais como a concep??o dial?gica de linguagem e as reflex?es atinentes ? analise dial?gica do discurso. A principal refer?ncia ? a obra de Bakhtin (2010b, 2010d) sobre a cosmovis?o carnavalesca, a par?dia, a estiliza??o e o riso carnavalesco. / In Brazil, in the 197 there was an effervescence in film production. In this period, erotic comedies were made and labeled pornochanchadas. These films made a big hit facing to the Brazilian public, but were always ridiculed by critics who judged them as evil done cinema. In this context, part of that film production can be classified as parody. So, this work whose subject is language and film has the object of investigation the construction of parodic discourse and carnival worldview in pornochanchada and is inserted in the area of Applied Linguistics in a socio-historical perspective. In order to carry out the analysis, we are reflecting on the investigation of verbal-visual elements present in the compositional form of three erotic comedies produced in the 1970s, as well as analyze the project of constitutor/constituent saying from architectural form. We take as a priority theoretical and methodological foundation of the formulations about language arising from Bakhtin Circle (2006, 2010), such as the dialogical approach of language and reflections relating to the dialogical discourse analysis. The main reference is the work by Bakhtin (2010b, 2010d) on the carnival worldview, the parody, the styling and the carnival laughter.

Entendemos que essa tens?o faz parte da subjetividade art?stica moderna, tendida entre a liberdade de recusa soberana e a aceita??o do compromisso com a hist?ria, de modo que ambos os autores acirram essa contradi??o da literatura. Se, por um lado, Blanchot (2011b) afirma que a literatura ? a porta para uma experi?ncia al?m dela mesma, experi?ncia que busca tornar a morte poss?vel, Sartre (2004) afirma que a literatura ? o ?mbito de uma rela??o entre liberdades onde tem lugar uma dial?tica fundamental que implica a tomada de consci?ncia. Ambos os autores concebem a realidade humana como negatividade, por isso a import?ncia de Hegel como fundo comum de onde a tens?o emerge. A filosofia hegeliana, atrav?s dos cursos de Alexandre Koj?ve (2012), com sua ?nfase na ideia de morte, ter? em Blanchot uma rearticula??o sem a qual n?o poder?amos compreender suas ideias sobre a literatura. Em Sartre, a filosofia hegeliana ? igualmente importante, uma vez que suas ideias sobre o existencialismo articulam n?o apenas a fenomenologia husserliana e o marxismo (posteriormente), mas a dial?tica da negatividade e do universal concreto. Para Blanchot, a literatura manifesta uma liberdade absoluta, uma interroga??o radical que p?e em causa todos os projetos humanos. Para Sartre, essa liberdade absoluta, que pode ter sido o af? do surrealismo, ? concebida como tenta??o da irresponsabilidade. A literatura permanece o lugar de uma ambiguidade que est? presente nos dois autores. / This dissertation is about the tension between Maurice Blanchot and Jean-Paul Sartre, as to the ethical, political and philosophical aspect of literature. We understand that this tension is part of modern artistic subjectivity, stretched between freedom of sovereign refusal and acceptance of commitment to history, so that both writers stir up this contradiction of literature. If, on the one hand, Blanchot (2011b) affirms that literature is the door to an experience beyond itself, an experience seeks to make death possible, Sartre (2004) says that literature is the space of a relation between freedoms where a fundamental dialectic takes place that implies an awareness. Both authors conceive the human reality as negativity, hence the importance of Hegel as common ground from which tension emerges. The Hegelian philosophy, through the courses of Alexandre Koj?ve (2012), with its emphasis on the idea of death, will have in Blanchot an rearticulation without which we could not understand his ideas about literature. In Sartre, Hegel?s philosophy is equally important, since his ideas about existentialism articulate not only phenomenology and Marxism (later), but the dialectic of negativity and the concrete universal. For Blanchot, literature manifests an absolute freedom, a radical interrogation that calls into question all human projects. For Sartre, this absolute freedom, which was the desire of surrealism, is conceived as a temptation to irresponsibility. The literature holds the place of an ambiguity that is present in the two authors.

The present study investigates the predictive accuracy of a key approach to interpretation of the verbal-spatialcognitive (VSC) and sensorimotor (SM) factors of the McCarron-Dial System (MDS). The subjects include 99 brain damaged and 30 normal adults. The following research questions are addressed: (a) Does the neuropsychological key classify brain damaged and non-brain damaged subjects at a level significantly above chance? (b) Among the brain damaged subjects, does the neuropsychological key identify right brain damage, left brain damage and diffuse brain damage at an accuracy level significantly above chance? (c) Is the neuropsychological key approach superior to the empirical model derived from discriminant function analysis in predictive accuracy? The neuropsychological key correctly classifies 90% of the cases as brain damaged and 90% of the cases as non-brain damaged, for a total of 89.9% predictive accuracy. The obtained Kappa coefficient of .74 is statistically significant. The key accurately classifies 71.4% of the brain damaged group as right damage, 70% as left damage, and 93.8% as diffuse damage, for a total predictive accuracy of 7 9.5%. The Kappa coefficient of .68 is statistically significant. Chi square analysis of the difference between the key approach and multiple discriminant function analysis reveals that no significant difference is present between the accuracy of the two approaches in differentiating between brain damaged and non-brain damaged, or in differentiating among left, right and diffuse brain damage. The results support the validity of a neuropsychological key approach to interpretation of the McCarron-Dial System, although cross-validation is indicated to confirm the stability of these results. Differences in sex, educational level and racial composition of the comparison groups may have affected the results obtained. Refinement of the key in future research and the addition of test instruments assessing memory, auditory processing, attention and emotional/behavioral variables are recommended.

Background: While farmers' markets are a potential strategy to increase access to fruits and vegetables in rural areas, more information is needed regarding use of farmers' markets among rural residents. Thus, this study's purpose was to examine (1) socio-demographic characteristics of participants; (2) barriers and facilitators to farmers' market shopping in southern rural communities; and (3) associations between farmers' market use with fruit and vegetable consumption and body mass index (BMI). Methods. Cross-sectional surveys were conducted with a purposive sample of farmers' market customers and a representative sample of primary household food shoppers in eastern North Carolina (NC) and the Appalachian region of Kentucky (KY). Customers were interviewed using an intercept survey instrument at farmers' markets. Representative samples of primary food shoppers were identified via random digit dial (RDD) cellular phone and landline methods in counties that had at least one farmers' market. All questionnaires assessed socio-demographic characteristics, food shopping patterns, barriers to and facilitators of farmers' market shopping, fruit and vegetable consumption and self-reported height and weight. The main outcome measures were fruit and vegetable consumption and BMI. Descriptive statistics were used to examine socio-demographic characteristics, food shopping patterns, and barriers and facilitators to farmers' market shopping. Linear regression analyses were used to examine associations between farmers' market use with fruit and vegetable consumption and BMI, controlling for age, race, education, and gender. Results: Among farmers' market customers, 44% and 55% (NC and KY customers, respectively) reported shopping at a farmers' market at least weekly, compared to 16% and 18% of NC and KY RDD respondents. Frequently reported barriers to farmers' market shopping were market days and hours, "only come when I need something", extreme weather, and market location. Among the KY farmers' market customers and NC and KY RDD respondents, fruit and vegetable consumption was positively associated with use of farmers' markets. There were no associations between use of farmers' markets and BMI. Conclusions: Fruit and vegetable consumption was associated with farmers' market shopping. Thus, farmers' markets may be a viable method to increase population-level produce consumption.

L’infrarouge proche (1.5-2μm) ou SWIR (Short Wavelength Infrared) est une région particulièrement adaptée à la mesure de gaz à effet de serre par lidar à absorption différen- tielle (DIAL). En effet, (i) cet intervalle spectral contient des raies d’absorption intenses pour les principaux gaz à effet de serre (CO2, CH4, H2O, etc.) (ii) le taux d’extinction lors de la propagation du faisceau laser y est faible (iii) c’est une région spectrale dite en sécurité oculaire. Bien qu’abordée avec les moyens existants (détection hétérodyne), la mesure DIAL dans le SWIR a longtemps souffert de l’absence de photo-détecteurs ultra-sensibles. Les développements récents (années 2000) portant sur les photodiodes à avalanche (APD) HgCdTe ont changé la donne. En effet, ces dernières présentent de remarquables qualités d’amplification car elles allient trois propriétés fondamentales : un faible excès de bruit, un très faible courant d’obscurité et des gains importants. De telles propriétés sont essentielles pour les applications reposant sur la détection de très faibles signaux et en particulier le lidar.Dans cette thèse, nous analysons les performances d’un détecteur monopixel (200 μm) à base d’APD HgCdTe (conçu sur mesure par le CEA-LETI) dans le cadre de mesures expérimentales de la concentration de CO2 atmosphérique par lidar DIAL. L’émetteur laser est également un prototype, précédemment développé au Laboratoire de Météoro- logie Dynamique. Il produit alternativement des impulsions de 10 mJ à deux fréquences contrôlées dans la plage 2050-2054nm, le tout à une fréquence de répétition de 2kHz. Grâce à l’association de ces deux technologies de pointe nous avons pu effectuer les pre- mières mesures DIAL utilisant la technologie HgCdTe APD.Les expériences menées nous ont permis de confirmer le remarquable niveau de per- formances en sensibilité attendu (75 photons de bruit par temps caractéristique d’une bande passante de 20 MHz) et soulignent le potentiel futur d’un tel capteur pour toutes les applications faible flux dans le SWIR. Concernant les mesures DIAL, nous avons ob- tenu expérimentalement une précision relative de 10-20 % sur la concentration en CO2 pour une mesure dans la couche limite avec une résolution de 100 m - 4 s sur une portée de 1.5km. Par ailleurs, l’analyse fine de la réponse impulsionnelle de la photodiode à avalanche révèle une dégradation notable du long term settling time lorsqu’on la pola- rise. Ce phénomène contraint la plage d’utilisation du capteur, ce que nous discutons en tenant ce comportement du détecteur dans une simulation lidar. / The Short Wavelength Infrared (SWIR) region (1.5-2 μm) is well adapted for diffe- rential absorption lidar technique (DIAL) for several reasons : (i) it covers absorption bands with suitable intensity for the main greenhouse gases (CO2, CH4, H2O, etc.) (ii) the extinction due to particles is low (iii) it belongs to the eye safe domain. However, one main drawback has long been the lack of efficient photodetectors for such frequencies. A major enhancement occurred in the early 2000s when it was understood that HgCdTe avalanche photodiodes (APD) present close to unity excess noise factor on top of high gain and very low dark current. These features make this technology an almost ideal amplifier, especially useful for ultra low flux applications such as lidar.In this thesis, we analyze the performances of a custom large diameter (200μm) monopixel HgCdTe-APD based detector (designed at CEA-LETI) in the framework of atmospheric CO2 measurements with the DIAL technique. The laser emitter, a custom solid-state Ho :YLF laser developed at the Laboratoire de Météorologie Dynamique, is tunable in the 2050-2054nm range and produces 10 mJ pulses at a repetition rate of 2kHz. This emitter is associated to a detection chain adapted to the HgCdTe APD based detector to provide the first atmospheric DIAL measurements using the HgCdTe APD technology.Experiments confirmed the outstanding sensitivity of the detector (75 noise photons per characteristic time given a 20MHz bandwidth) and highlight the huge potential of this technology for any application relying on low light flux detection in SWIR. With the system previously mentioned, we reach an precision of 10-20 % on CO2 mixing ratio for a time-space resolution of 100 m and 4 s for measurements in the atmospheric boundary layer. Regarding the detector impulse response, we have shown evidence of a negative influence of reverse bias on the long term settling time of the APD. This phenomenon limits the dynamic range of useful signals and contraints the DIAL system. Thanks to numerical simulation taking into account this behaviour, we derive numerically expected biases on DIAL measurements.
