Esses formadores desenvolvem a??es voltadas para a preven??o ao abuso de drogas l?citas e ao uso de drogas il?citas, bem como divulgam, atrav?s de relatos, suas a??es, iniciativas e campanhas de preven??o em uma rede operativa virtual. Assim sendo, a pesquisa proposta tem como objeto de estudo os posts do blog PROERD no Sert?o, publicados por policiais militares da regi?o do Serid?/RN. Sua configura??o em dom?nio virtual contempla posts de a??es desenvolvidas junto a alunos de escolas p?blicas do Ensino Fundamental e comunidade, na perspectiva de chamar a aten??o para a preven??o quanto ao uso e abuso de drogas l?citas e il?citas. Nesse sentido, a pesquisa objetiva analisar eventos e pr?ticas de letramento implementados por policiais proerdianos no que se refere ? produ??o e ? publica??o de posts no referido blog. Em termos te?ricos, apoia-se nos pressupostos dos Estudos de Letramento como pr?tica social (BARTON; HAMILTON, 1993, 1998, 2000; KLEIMAN, 1995, 2008; STREET, 1984; OLIVEIRA, 2008, 2010; ROJO, 2009), na teoria dos g?neros (OLIVEIRA, 2010; BRONCKART, 2004, 2006), nos estudos dos elementos de dimens?o pragm?tica, esquem?tica e lingu?stica (KOCH; F?VERO, 1987), nos estudos da multimodalidade (KRESS; VAN LEEUWEN, 2006 [1996]; DION?SIO, 2006; SANTAELLA, 2012; ALMEIDA, 2011), nos conceitos de agenciamento (BANDURA, 2001), hipertexto e hiperm?dia (NOJOSA, 2007; KOMESU, 2004; GOMES, 2010; KARWOSKY, 2012; FERRARI, 2007), bem como nos fundamentos que tematizam linguagem e trabalho (SOUZA-E-SILVA, 2002; DUARTE; FEITOSA, 1998; PAZ, 2008, 2010). Metodologicamente, a investiga??o se insere no campo da Lingu?stica Aplicada (MOITA-LOPES, 1996, 2006; PENNYCOOK, 2006), segue abordagem de natureza qualitativa e assume caracter?sticas da pesquisa explicativa (MOREIRA; CALEFFE, 2006; BOGDAN; BIKLEN, 1994; MINAYO, 2010; CHIZZOTTI, 2005). A gera??o de dados se desenvolve por meio de t?cnicas padronizadas (GIL, 1994) que compreendem entrevistas e question?rios, as quais possibilitam o ?cruzamento? ou a triangula??o de informa??es (COX; ASSIS-PETERSON, 2001). As discuss?es dos dados convergem para a revisita??o das categorias (elementos e componentes) propostas por Hamilton (2000), ao analisar eventos e pr?ticas de letramento, assim como para a focaliza??o dos movimentos verticais (telerrealidade, cibercultura) e horizontais (conviv?ncia/televiv?ncia; local/global; espa?o geogr?fico/eletr?nico) que se presentificam no hiperdom?nio (ciberespa?o, blogosfera). A relev?ncia da pesquisa situa-se no fato de trazer para o ?mbito acad?mico t?picos espec?ficos do dom?nio do trabalho, mais precisamente do ?mbito da pol?tica de seguran?a p?blica, com vistas a contribuir para a amplia??o dos Estudos de Letramento. Igualmente, a import?ncia social da pesquisa constitui-se significativa pelo fato de trazer visibilidade acad?mica para os colaboradores, vislumbrando-os como agentes potenciais da seguran?a p?blica, capazes de realizar mudan?as sociais em termos de a??o instrumental e de a??o simb?lica ou comunicativa (MAGALH?ES, 1994), tornando a pr?tica de produ??o de posts uma a??o autoconsciente e reflexiva, mesmo em meio ?s contradi??es dos processos sociais que dificultam a plena efetiva??o das Pol?ticas P?blicas Antidrogas no Brasil. / This study consists of the analyses of literacy events and practices in an anti-drug public policy context, more precisely with research locus formed by the operation of military police officers from PROERD (Educational Program of Resistance to Drugs). The aforementioned trainers perform actions intended to prevent licit and illicit drug abuse, as well as divulge their actions, initiatives and prevention campaigns through actions? reports in a virtual operating network. Therefore, the object of study are the posts from the blog ?PROERD no Sert?o? (PROERD in the backlands) created by military police officers from the region of Serid?/RN. In virtual domain, it contemplates posts of the actions developed along with students from Elementary public schools and community, with a view to direct attention to the prevention of licit and illicit drug use and abuse. The study aims to analyze the literacy events and practices implemented by PROED officers in respect to the productions and publishing of posts in the referred blog. In theoretical terms, it is based on the pressupositions of Literacy Studies as social practice (BARTON; HAMILTON, 1993, 1998, 2000; KLEIMAN, 1995, 2008; STREET, 1984; OLIVEIRA, 2008, 2010; ROJO, 2009), on genre theory (OLIVEIRA, 2010; BRONCKART, 2004, 2006), on studies of elements of linguistic, schematic and pragmatic dimension (KOCH; F?VERO, 1987), on studies about multimodality (KRESS and VAN LEEUWEN, 2006 [1996]; DION?SIO, 2006; SANTAELLA, 2012; ALMEIDA, 2011), on concepts of agency (BANDURA, 2001), hypertext and hypermedia (NOJOSA, 2007; KOMESU 2004; GOMES, 2010; KARWOSKY, 2012; FERRARI, 2007), as well as on fundamentals which have language and work as theme (SOUZA and SILVA, 2002; DUARTE; FEITOSA, 1998; PAZ, 2008, 2010). Methodologically, this investigation inserts into the Applied Linguistics field (MOITA-LOPES, 1996, 2006; PENNYCOOK, 2006) and follows a qualitative approach, bearing descriptive research characteristics (MOREIRA; CALEFFE, 2006; BOGDAN; BIKLEN, 1994; MINAYO, 2010; CHIZZOTTI, 2005). Data generation was developed through standard techniques (GIL, 1994) which comprise interviews and questionnaires and enable the ?intersection? or triangulation of information (COX; ASSIS-PETERSON, 2001). Data discussion converge to the revisitation of categories (elements and components) proposed by Hamilton (2000), when analyzing literacy events and practices, as well as the focalization of vertical (tele-reality, cyberculture) and horizontal (living/tele-living; local/global; geographical/electronic space) movements that are evoked in hyperdomain (cyberspace, blogsphere). The relevance of this study lies in the fact of bringing specific topics from the work domain to the academic realm, more specifically from the public security policy with a view to contribute to the expansion of Literacy Studies. Equally, the social importance of this study is significant due to the academic visibility it provides for the collaborators, depicting them as potential agents of public security, able to make social changes in terms of instrumental and communicative or symbolic action (MAGALH?ES, 1994). This makes the practice of writing posts a self-conscious and reflexive action, even amid the contradictions of the social processes, which hamper the full effectuation of Anti-drug Public Policies in Brazil.

Esta condi??o cl?nica pode causar hipersensibilidade dentin?ria cervical (HSDC), comprometendo a est?tica e interferindo na qualidade de vida. O objetivo deste trabalho foi avaliar o efeito do recobrimento radicular na HSDC, est?tica e qualidade de vida de pacientes portadores de retra??es gengivais classe I e II de Miller. O objetivo secund?rio foi avaliar os fatores etiol?gicos de retra??o gengival. Vinte e dois pacientes com idade variando entre 18 a 50 anos apresentaram 25 retra??es gengivais em dentes caninos e pr?-molares superiores sens?veis. Os seguintes par?metros cl?nicos foram avaliados: largura e altura das retra??es gengivais nas faces vestibulares foram medidas com um compasso de ponta seca e aferidas com o aux?lio de um paqu?metro. Tamb?m avaliou-se a altura e espessura da gengiva queratinizada, ?ndice de placa, sangramento ? sondagem, profundidade de sondagem e n?vel de inser??o cl?nica. A HSDC foi avaliada utilizando est?mulos evaporativo (jato de ar) e t?rmico (Endo-Ice?) por 5 segundos. Para mensura??o da hipersensibilidade utilizou-se escala de avalia??o num?rica. A satisfa??o est?tica e qualidade de vida foram avaliadas pelos pacientes e pelo question?rio OHIP-14 modificado, respectivamente. A etiologia das retra??es gengivais tamb?m foi investigada atrav?s de anamnese e exame cl?nico. Todas as retra??es foram tratadas atrav?s da t?cnica cir?rgica de retalho posicionado coronalmente associado ao enxerto conjuntivo subepitelial. Os par?metros cl?nicos foram avaliados no baseline e 3 meses ap?s o tratamento. A m?dia de recobrimento radicular, ap?s 90 dias, foi de 67,90%. Completo recobrimento radicular foi alcan?ado em 44% dos dentes tratados. Foi obtido redu??o estatisticamente significativa na HSDC (p <0,001), na melhora da qualidade de vida (p <0,001), e melhora dos par?metros periodontais ap?s 3 meses. Todos pacientes ficaram satisfeitos com a est?tica alcan?ada. Houve correla??o entre qualidade de vida e est?tica. N?o houve correla??o entre a porcentagem de recobrimento radicular e HSDC estimulada por ar (p = 0,256) ou frio (p = 0,563). Houve correla??o entre a dimens?o defici?ncia f?sica do OHIP-14 e quantidade de tecido queratinizado (p = 0,010) e recobrimento radicular (p = 0,035). Conclui-se que o recobrimento radicular apresentou um efeito positivo na HSDC e qualidade de vida, com melhora dos par?metros cl?nicos periodontais. O principal fator etiol?gico identificado para a retra??o gengival foi o trauma devido ? escova??o. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Odontologia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2013. / ABSTRACT Gingival recession is the apical displacement of the gingival margin in relation to the cement-enamel junction, leading to root exposure. This condition may cause cervical dentin hypersensitivity (CDH), compromising the esthetics and interfering with quality of life. The objective of this study was to evaluate the effect of root coverage on the CDH, aesthetics and quality of life of patients with gingival recessions class I and II Miller. The secondary aim was to investigate the etiologic factors of gingival recessions. Twenty-two patients aged 18-50 years presented 25 gingival recessions in sensitive upper canines and premolars. The following parameters were assessed: width and height of the gingival recessions were assessed with a compass needle point and measured with a caliper. It was assessed the height and thickness of keratinized gingiva, plaque index, bleeding on probing, probing depth and clinical attachment level. The CDH was assessed by evaporative (air jet) and thermal (Endo-Ice?) stimuli for 5 seconds. Dentin hypersensitivity was measured using a numerical scale. The aesthetic satisfaction and quality of life were evaluated by the patients and the OHIP-14 form, respectively. The gingival recession etiology was also investigated by anamnesis and clinical exam. All gingival defects were surgically treated by the coronally advanced flap technique combined with sub-epithelial connective tissue graft. All clinical parameters were evaluated at baseline and 3 months after treatment. The mean root coverage after 90 days was 67.90%. Complete root coverage was achieved in 44% of the treated teeth. There was a statistically significant decrease in CDH (p <0.001), improvement in quality of life (p <0.001), and improvement in periodontal parameters after 3 months. All patients were satisfied with the aesthetics achieved. There was a correlation between quality of life and aesthetics. The percentage of root coverage was not correlated with the CDH stimulated by air (p = 0.256) or cold (p = 0.563). There was a correlation between the disability dimension of OHIP-14 form and the amount of keratinized tissue (p = 0.010) and root coverage (p = 0.035). It was concluded that the root coverage had a positive effect on CDH and quality of life. The clinical periodontal parameters were improved. In addition, it was noted that the main etiologic factor identified for the gingival recession was trauma due to brushing.

We tested the hypothesis that different component orientations may influence the structure and floristic changes. In a sample area of 9.700 m2, divided into ten areas, were surveyed 1508 individuals, distributed in 324 species, 154 genera and 52 families. The families richest in species were: Myrtaceae, Lauraceae, Fabaceae, Rubiaceae and Euphorbiaceae. The Diversity Index Shannon-Wiener (H ') was 5.093 nats / indiv., And the evenness (J) was 0.881. Horizontal structure in the species Joannesia princeps, Piptadenia gonoacantha e Pseudopiptadenia contorta, Meternichia princeps, Apuleia leiocarpa, Astrocaryum aculeatissimum, Chrysophyllum flexuosum reached the highest value of phytosociological importance. A phytosociological analysis of each individual area indicated significant floristic and structural variations, with a trend toward greater diversity is found in areas of higher altitude and farther from the urban perimeter. Of the 324 species found in the study, 124 were found exclusively on the north side, 100 on the southern slope and 100 occurred in both strands. The exclusive species and more frequent on the north side were Brosimum guianense e Annona cacans, Zollernia ilicifolia, Couratari pyramidata, Lecythis pisonis e Gallesia integrifolia. On the southern slope, the exclusive species that stood out were Cariniana estrellensis, Cabralea canjerana, Eugenia microcarpa. Cluster analysis among the ten areas indicated, in general, greater similarity due to the proximity between areas than for the orientation of the slope, however comparing the north and south closer together, it is observed that the highest diversity indices, most proportion of rare species and unique and the most advanced stages of succession were found on the southern slope. The cases where this did not happen were observed in areas closer to the urban boundaries that regardless of the slope were less floristic diversity. The diameter distribution model presented inverted J, with a diameter range quite variable between areas. No pattern was found between the diameter distribution and orientation of the slope. Comparing the flora of Pedra Branca with other forest areas in Rio de Janeiro, there was generally a low floristic similarity. The major floristic identity occurred with the work in-house Pedra Branca, Serra da Tiririca, and Tijuca Forest. Works out of the city showed floristic similarity below 25%. The high diversity of the studied area is a reflection of its high environmental heterogeneity, related to differences in altitude, slope orientation, successional stage and history of use, which puts the Pedra Branca as a strategic area for species conservation in Rio de Janeiro. / Este trabalho teve como objetivo avaliar a estrutura e a flor?stica do estrato arbustivo e arb?reo em ?reas de encostas norte e sul, na por??o meridional do maci?o da Pedra Branca, Rio de Janeiro, RJ. Foi testada a hip?tese que diferentes orienta??es de vertente podem influenciar a estrutura e a flor?stica da vegeta??o. Em uma ?rea amostral de 9.700 m2, distribu?das em dez ?reas, foram inventariados 1.508 indiv?duos, distribu?dos em 324 esp?cies, 154 g?neros e 52 fam?lias. As fam?lias mais ricas em esp?cies na foram: Myrtaceae, Lauraceae, Fabaceae, Rubiaceae e Euphorbiaceae. O ?ndice de Diversidade de Shannon- Wiener (H?) foi de 5,093 nats/indiv., e a equabilidade (J) foi de 0,881. Na estrutura horizontal as esp?cies Joannesia princeps, Piptadenia gonoacantha e Pseudopiptadenia contorta, Meternichia princeps, Apuleia leiocarpa, Astrocaryum aculeatissimum, Chrysophyllum flexuosum alcan?aram o maior valor de import?ncia fitossociol?gico. A an?lise fitossociol?gica de cada ?rea indicou importantes varia??es estruturais e flor?sticas, com tend?ncia ? maior diversidade ser encontrada nas ?reas de maior altitude e mais distantes do per?metro urbano. Das 324 esp?cies encontradas no trabalho, 124 ocorreram exclusivamente na vertente norte, 100 na vertente sul e 100 ocorreram em ambas as vertentes. As esp?cies exclusivas e mais freq?ente na vertente norte foram o Brosimum guianense e Annona cacans, Zollernia ilicifolia, Couratari pyramidata, Lecythis pisonis e Gallesia integrifolia. Na vertente sul, as esp?cies exclusivas que mais se destacaram foram Cariniana estrellensis, Cabralea canjerana, Eugenia microcarpa. A an?lise de agrupamento entre as dez ?reas indicou, em geral, maior semelhan?a em decorr?ncia da proximidade entre ?reas do que pela orienta??o da encosta, entretanto comparando as vertentes norte e sul mais pr?ximas, observase que os maiores ?ndices de diversidade, a maior propor??o de esp?cies raras e exclusivas e os est?gios de sucess?o mais avan?ados foram encontradas na vertente sul. Os casos em que isso n?o ocorreu foram observados nas ?reas mais pr?ximas ao per?metro urbano que, independente da vertente apresentaram menor diversidade flor?stica. A distribui??o diam?trica apresentou modelo do J invertido, sendo a amplitude diam?trica bastante vari?vel entre ?reas. N?o foi encontrado um padr?o entre distribui??o diam?trica e a orienta??o da encosta. Comparando a flor?stica do trecho estudado do Maci?o da Pedra Branca com outras ?reas florestais do Rio de Janeiro, observou-se uma baixa similaridade flor?stica. A maior identidade flor?stica ocorreu com trabalhos realizados na pr?pria Pedra Branca, na Serra da Tiririca, e na Floresta da Tijuca. Trabalhos fora do munic?pio apresentaram similaridade flor?stica inferior a 25%. A elevada diversidade da ?rea estudada ? reflexo da sua alta heterogeneidade ambiental, relacionada a diferen?as na altitude, orienta??o de encosta, est?gio sucessional e hist?rico de uso, o que coloca a Maci?o da Pedra Branca como ?rea estrat?gica para conserva??o de esp?cies do munic?pio do Rio de Janeiro.

In Brazil, 59.9% of new ventures do not reach the fourth year of life, the mortality rate of new ventures is high. The causes of mortality are numerous, and within the behavioral aspects, one is the locus of control. This study determines the degree of association between internal locus of control and achieving business success of entrepreneurs in Rio Grande do Norte who participated in the workshop EMPRETEC. The approach that studies the behavior entrepreneurs agreed that there are psychological characteristics associated with a set of values, attitudes and needs that determine the behavior and induce the entrepreneur to achieve success. Among these features is the locus of control, a skill that individuals must identify in their actions, or lack of them, the causes of their successes and failures. The locus is external when the individual attributes to factors outside themselves as causes of their results, and is built in when you can identify the actions that led to success. We surveyed 223 entrepreneurs statewide who answered the questionnaire for assessing the scale of locus of control, selfassessment questionnaire of entrepreneurial characteristics of EMPRETEC and a questionnaire assessing the business success. 71.9% were identified as having success. Among the behavioral characteristics strongest in the group of entrepreneurs are setting goals and commitment. Was found for locus of control mean value of 7.35, confidence interval between 7.05 and 7.66. Showing that the locus of control group is predominantly internal. We also found a correlation between the locus and commitment, between setting goals and commitment; calculated risks and information search; search of information and commitment, and between commitment and independence and self confidence. Dependence was not identified among the set of features and business success, determining the absence of an ideal profile. However, logistic regression significant association was found indicating that the smaller the individual's locus of control increased the likelihood of it achieving business success / Os empreendedores s?o indiv?duos que podem transformar realidades econ?micas e sociais promovendo desenvolvimento, por isto tornaram-se pe?as importantes na gera??o de externalidades nas regi?es onde atuam. No Brasil 59,9% dos novos empreendimentos n?o chegam ao quarto ano de vida, esta taxa de mortalidade de novos empreendimentos ? alta. As causas a mortalidade s?o in?meras, e dentro dos aspectos comportamentais, uma delas ? o locus de controle. Este estudo determina o grau de associa??o entre o locus de controle interno e a obten??o de efetividade empresarial em empreendedores do Rio Grande do Norte que participaram do workshop EMPRETEC. A abordagem que estuda os comportamentos empreendedores preconiza que existem caracter?sticas psicol?gicas associadas a um conjunto de valores, atitudes e necessidades que determinam o comportamento e induzem o empreendedor ? obten??o de efetividade. Dentre estas caracter?sticas est? o locus de controle, capacidade que os indiv?duos t?m de identificar em suas a??es, ou na aus?ncia delas, as causas de seus sucessos e fracassos. O locus ? externo quando o indiv?duo atribui a fatores fora de si como causas de seus resultados, e ? interno quando consegue identificar dentro si as a??es que o conduziram ao sucesso. Foram pesquisados 223 empreendedores em todo estado que responderam o question?rio de avalia??o da escala do locus de controle, o question?rio de autoavalia??o das caracter?sticas empreendedoras do EMPRETEC e um question?rio de avalia??o da efetividade empresarial. 71,9% deles foram identificados como tendo efetividade. Dentre as caracter?sticas comportamentais mais fortes no grupo de empreendedores est?o o estabelecimento de metas e o comprometimento. Foi encontrado para o locus de controle o valor m?dio de 7,35, com intervalo de confian?a entre 7,05 e 7,66. Mostrando que o locus de controle do grupo ? predominantemente interno. Tamb?m foi encontrada correla??o entre o locus e comprometimento; entre estabelecimento de metas e comprometimento; correr riscos calculados e busca de informa??es; busca de informa??es e comprometimento; e entre o comprometimento e independ?ncia e autoconfian?a. N?o foi identificada depend?ncia entre o conjunto das caracter?sticas e a efetividade empresarial, determinando assim a n?o exist?ncia de um perfil ideal. No entanto, atrav?s de regress?o log?stica significante foi encontrada associa??o que indica que quanto menor o locus de controle do individuo maior a probabilidade dele alcan?ar a efetividade empresarial

This fields of study can be grouped into three major groups: heuristic bias, tying the shape and inefficient markets. The present study focuses on issues concerning the heuristics of representativeness and anchoring. This study aimed to identify the then under-reaction and over-reaction, as well as the existence of symmetry in the active first and second line of the Brazilian stock market. For this, it will be use the Fuzzy Logic and the indicators that classify groups studied from the Discriminant Analysis. The highest present, indicator in the period studied, was the Liabilities / Equity, demonstrating the importance of the moment to discriminate the assets to be considered "winners" and "losers." Note that in the MLCX biases over-reaction is concentrated in the period of financial crisis, and in the remaining periods of statistically significant biases, are obtained by sub-reactions. The latter would be in times of moderate levels of uncertainty. In the Small Caps the behavioral responses in 2005 and 2007 occur in reverse to those observed in the Mid-Large Cap. Now in times of crisis would have a marked conservatism while near the end of trading on the Bovespa speaker, accompanied by an increase of negotiations, there is an overreaction by investors. The other heuristics in SMLL occurred at the end of the period studied, this being a under-reaction and the other a over-reaction and the second occurring in a period of financial-economic more positive than the first. As regards the under / over-reactivity in both types, there is detected a predominance of either, which probably be different in the context in MLCX without crisis. For the period in which such phenomena occur in a statistically significant to note that, in most cases, such phenomena occur during the periods for MLCX while in SMLL not only biases are less present as there is no concentration of these at any time . Given the above, it is believed that while detecting the presence of bias behavior at certain times, these do not tend to appear to a specific type or heuristics and while there were some indications of a seasonal pattern in Mid- Large Caps, the same behavior does not seem to be repeated in Small Caps. The tests would then suggest that momentary failures in the Efficient Market Hypothesis when tested in semistrong form as stated by Behavioral Finance. This result confirms the theory by stating that not only rationality, but also human irrationality, is limited because it would act rationally in many circumstances / As Finan?as Comportamentais desenvolvem-se ? medida em que s?o percebidas anomalias nos ditos mercados eficientes. Seus campos de estudos podem ser reunidos em tr?s grandes grupos: vi?s heur?stico, subordina??o a forma e mercados ineficientes. O presente estudo foca-se em quest?es relativas ?s heur?sticas da representatividade e do ancoramento. O presente trabalho objetivou ent?o identificar a sub-rea??o e sobre-rea??o, assim como a exist?ncia de simetria nos ativos de primeira e segunda linha do mercado acion?rio brasileiro. Para tal foi utilizada a L?gica Fuzzy e os indicadores que classificam os grupos, estudados a partir da An?lise Discriminante. O ?ndice mais presente, nos per?odos estudados, foi o de Exig?vel/Patrim?nio L?quido, demonstrando a import?ncia deste no momento de discriminar os ativos a serem considerados vencedores e perdedores . Nota-se na MLCX que os vieses de sobre-rea??o se concentram no per?odo da crise financeira, sendo que nos demais per?odos, de vieses significantes estatisticamente, s?o obtidas sub-rea??es. Estas ?ltimas se dariam em momentos de n?veis moderados de incertezas. Nas Small Caps as rea??es comportamentais em 2005 e 2007 ocorrem de forma inversa ?s observadas nas Mid-Large Caps. Agora em momentos de crise ter-se-ia um marcado conservadorismo enquanto que nas proximidades do fim do preg?o viva-voz da Bovespa, acompanhado do aumento das negocia??es realizadas, nota-se uma rea??o excessiva por parte dos investidores. As demais heur?sticas nas SMLL ocorreram no final do per?odo em estudo, sendo esta uma de sub e outra de sobre-rea??o e a segunda ocorrendo em um per?odo financeiro-econ?mico mais positivo que a primeira. No que diz respeito a sub/sobre-rea??o em ambos tipos, n?o se detecta a predomin?ncia de nenhum destes, fato que provavelmente seria diferente nas MLCX em um contexto sem crise. Quanto ao per?odo em que tais fen?menos se d?o de forma significante estatisticamente notase que, em sua maioria, tais fen?menos ocorrem nos ?ltimos per?odos para as MLCX enquanto nas SMLL n?o apenas os vieses s?o menos presentes como tamb?m n?o h? concentra??o destes em nenhum per?odo. Diante do exposto, acredita-se que, embora detectese a presen?a de vieses comportamentais em certos per?odos, estes n?o aparentam tender a um tipo espec?fico de heur?stica ou e embora existam alguns ind?cios de uma sazonalidade nas Mid-Lage Caps, este mesmo comportamento n?o parece se repetir nas Small Caps. Os testes realizados sugerem ent?o que haveriam falhas moment?neas na Hip?tese de Mercados Eficientes quando testada em sua forma semi-forte conforme afirmado pelas Finan?as Comportamentais. Este resultado corrobora com a teoria ao afirmar que n?o apenas a racionalidade, mas tamb?m a irracionalidade humana, ? limitada, pois agir-se-ia racionalmente em in?meras circunst?ncias

The main topics highlight the conflict between the right to housing and the prevalence of fundamental rights of traditional populations, opposed to the diffuse right to environment, according to the regulatory framework of the Brazilian Urban and Environmental Policies. At the same time that these settlements, historically built, are substantiated by the principles of recognition of rights to traditional populations, they are in a condition of complexity to the resolution of conflicts in its urban dimension and lead to an impairment of natural sites. This work questions how the instruments of land use and occupation are defined and relate to environmental planning, especially considering that the settlements are located in Permanent Preservation Areas (APP). It aims to further the discussion of the urban dimension in settlements, characterizing its formation and growth process, to identify the gaps and convergences between the Urban and Environmental Policy, under the foundations of a socio-environmental approach. The results spotlights the conflicts between occupation and natural areas, inferring that the definition of Urban Policies instruments and its integration with Environmental Policies instruments account for essential and priority actions to the achievement to the rights to a sustainable city, as determined in the Cities Statute and environmental protection goals, defined for the Conservation Units / O presente trabalho apresenta uma reflex?o sobre possibilidades e limites de consolida??o e expans?o de assentamentos humanos caracterizados como comunidades tradicionais que se encontram situados em ?reas protegidas, tendo como refer?ncia de estudo a Reserva de Desenvolvimento Sustent?vel Estadual Ponta do Tubar?o (RDSEPT), no estado do Rio Grande do Norte. As quest?es centrais evidenciam o conflito entre o direito ? moradia e a preval?ncia dos direitos fundamentais das popula??es tradicionais, em contraponto com o direito difuso ao meio ambiente, segundo o marco regulat?rio das Pol?ticas Urbana e Ambiental brasileiras. Ao mesmo tempo em que esses assentamentos, historicamente constitu?dos, s?o respaldados pelos princ?pios do reconhecimento dos direitos relativos ?s popula??es tradicionais, eles se encontram em uma condi??o de complexidade para a resolu??o dos conflitos presentes na sua dimens?o urbana e que levam a um comprometimento dos espa?os naturais. O trabalho questiona como os instrumentos de uso e ocupa??o do solo se definem e se relacionam com o planejamento ambiental, considerando principalmente que as ocupa??es se encontram em ?reas de Preserva??o Permanente (APP). Tem como objetivo aprofundar a discuss?o da dimens?o urban?stica presente nos assentamentos, caracterizando seu processo de forma??o e crescimento, buscando identificar as converg?ncias e lacunas entre a Pol?tica Ambiental e a Urbana, sob os fundamentos da abordagem socioambiental. Os resultados evidenciam os conflitos presentes entre a ocupa??o e as ?reas naturais, demonstrando que a defini??o de instrumentos de Pol?tica Urbana e sua integra??o com os instrumentos da Pol?tica Ambiental constituem a??es indispens?veis e priorit?rias para a consecu??o dos direitos ? cidade sustent?vel, conforme definidos no Estatuto da Cidade e os objetivos de prote??o ambiental definidos para as Unidades de Conserva??o

The new formalism is based on the following generalizations: i) Maxwell- Boltzmann-Gibbs entropy and ii) deduction of H-theorem. Based on this investigation, we calculate a new entropy using a generalization of combinatorial analysis based on two different methods of counting. The basic ingredients used in the H-theorem were: a generalized quantum entropy and a generalization of collisional term of Boltzmann equation. The power law distributions are parameterized by parameters q;, measuring the degree of non-Gaussianity of quantum gas. In the limit q ?1; ?0, the gaussian thermostatistics is recovered. A complementary study is related to a perfect gas in the context of general relativity. Using the non-Gaussian effects on the concept of entropy flux, and on the collisional term of the Boltzmann equation, we generalize the H-theorem within the Tsallis and Kaniadakis frameworks. In the first one, the nonextensive parameter is constrained to the interval [0,2] / Considerando um g?s qu?ntico, os fundamentos da termoestat?stica padr?o s?o investigados no contexto da mec?nica estat?stica n?o-gaussiana introduzida por Tsallis e Kaniadakis.

These general conceptual metaphors had been unfolded in other s more specific ones ( animal specifying itself in lion , dragon , dog , etc.). Another result was the identification of metaphoric expressions with two or more meanings , with relation to more than one conceptual metaphor or explicit, in the same expression, two domains-source (for example: armored dragon ) and contributes, of a relevant form, for the semantic struturation of the text. The understanding of the metaphors was verified through an activity of domains-source s identification (10 metaphoric statements and fulfilling of the gap in the phrase the inflation is a/an ) applied in a group of 8th year of the basic education (12-13 years old, with 14 girls and 17 boys) from a school of good social and economic positions from Natal-RN. There weren t great difficulties on the part of the students in recognizing the domains-source involved: about 80% to the great majority of the statements / A pesquisa visou a dois objetivos: 1?) identificar e descrever as met?foras da infla??o, em um corpus de 18 textos de jornalismo econ?mico, de autoria de Joelmir Beting, escritos no ?ltimo trimestre de 2002, no momento da transi??o do governo do presidente Fernando Henrique Cardoso para o do presidente eleito Luiz In?cio Lula da Silva. 2?) verificar o reconhecimento das met?foras por parte de alunos do ensino fundamental de uma escola particular de Natal. Foram identificadas 91 met?foras, analisadas na perspectiva da teoria da met?fora conceitual, de Lakoff e Johnson (2002), com base na distin??o entre met?fora conceitual / express?es metaf?ricas, e entre dom?nio-fonte / dom?nio-alvo. Foram depreendidas 10 met?foras conceituais subjacentes, sendo que os dom?nios-fonte mais freq?entemente utilizados para caracterizar a infla??o foram aqueles ligados ao ser humano e aos animais e, de forma menos previs?vel, aos meios de transporte (carro, aeronave). Essas met?foras conceituais gerais, foram desdobradas em outras mais espec?ficas ( animal especificando-se em le?o , drag?o , cachorro , etc.). Um outro resultado foi a identifica??o de express?es metaf?ricas poliss?micas , que remetem a mais de uma met?fora conceitual ou explicitam, na mesma express?o, dois dom?nios-fonte (por exemplo: drag?o blindado ) e contribuem, de forma relevante, para a estrutura??o sem?ntica do texto. A compreens?o das met?foras foi verificada atrav?s de uma atividade de identifica??o de dom?nios-fonte (10 enunciados metaf?ricos e preenchimento da lacuna na frase A infla??o ? um/uma... ) aplicada em uma turma de 8? ano do ensino fundamental (12-13 anos de idade, sendo 14 meninas e 17 meninos) de uma escola de classe m?dia-alta de Natal-RN.
