Esta pesquisa teve como objetivo investigar as representações sociais de um grupo de professores de inglês em curso livre a respeito de sua identidade profissional, seus processos formativos e seus saberes docentes. A fundamentação teórica do estudo baseou-se nos conceitos de representação social (Serge Moscovici e Denise Jodelet) e de dialogicidade (Mikhail Bakhtin e Ivana Marková). Foram realizadas considerações a respeito de fatores históricos, sociais e econômicos que originaram as atuais representações que os sujeitos do estudo têm a respeito do idioma bem como dos processos de ensino e aprendizagem do mesmo. Os dados foram coletados através de dois questionários e analisados com os recursos de um software para análise lexical, o ALCESTE. Os resultados revelaram que os participantes consideram a fluência no idioma como central para sua identidade profissional e a experiência em sala de aula como mais importante do que a vivência acadêmica. A falta de reflexão acerca de aspectos sociais relacionados à sua prática pedagógica também foi observada. A contribuição pretendida por este estudo foi uma melhor compreensão das representações de professores de inglês a respeito do idioma e dos processos de ensino e aprendizagem do mesmo, bem como de seu papel profissional, de forma a oferecer algumas reflexões sobre as políticas e práticas atuais relacionadas à formação inicial e continuada de professores de língua estrangeira.(AU)

Este estudo apresenta uma discussão a respeito de drogas e de alunos usuários de drogas na escola, explorando as Representações Sociais manifestadas por professores que atuam na Rede Estadual de São Paulo, no ensino Médio. O estudo resgata aspectos históricos e sociais que influenciaram representações sociais sobre drogas em diferentes contextos da sociedade, na perspectiva de buscar compreender a maneira como atualmente elas se apresentam. Discute aspectos conceituais da Teoria das Representações Sociais a partir de Moscovici, considerando contribuições de Jodelet, e outros autores. Os dados coletados por meio de questionários e entrevistas foram analisados com o auxílio de dois softwares, o ALCESTE para análise lexical e o EVOC para análise de associação de palavras ou expressões, em articulação com uma análise de conteúdo clássica sugerida por Maria Laura Puglisi Barbosa Franco. O resultado identificou que as representações sociais sobre drogas na escola e alunos usuários estão ancoradas no modo como a grande mídia trata o tema, de forma alarmista e sensacionalista, influenciando grande parte dos professores que associa drogas na escola à violência. Verificou-se ainda que objetivação do aluno usuário de drogas é simbolizada como doença e que o grupo pesquisado segue as representações sociais há muito tempo estruturadas na sociedade, tendo a normalidade como sinônimo de saúde e a drogadição como condição desviante, decorrente de patologias. Assim, espera-se estar contribuindo para a reflexão sobre o uso e abuso de drogas nas escolas, um tema indispensável e que precisa ser enfrentado para construir-se uma via que leve a uma Educação justa e democrática.(AU)

O presente trabalho analisa as origens do modelo de Escola Pública de Tempo Integral, a partir de uma abordagem histórica que compara dois modelos: o da Escola-parque e a proposta implantada em 2006, no Estado de São Paulo. Investiga a questão com base na Teoria das Representações Sociais de Moscovici com o intuito de desvelar as representações sociais de professores, para aprofundar a reflexão sobre a sua inserção e preparação para a atuação neste modelo de escola. Prioriza, também, uma discussão sobre uma divisão que se percebe no contexto da Escola Pública de Tempo Integral, que se refere a uma distinção entre a proposta de atividades desenvolvidas sobre as atividades do currículo normal (consideradas mais importantes) e as atividades de extensão do currículo oficinas (consideradas menos importantes), cujas diferenças são geradas pela ausência de preparação destes profissionais nos processos formativos do projeto.(AU)

Esta pesquisa teve como objetivo investigar as representações sociais de um grupo de pedagogos docentes em faculdades isoladas, nos cursos de Pedagogia, a respeito de sua identidade profissional. A fundamentação teórica do estudo baseou- se nos conceitos de Representação Social enunciados por Sèrge Moscovici e Denise Jodelet. Foram realizadas considerações acerca dos caminhos percorridos pelos cursos de Pedagogia no país e seus aspectos sociais, que deram origem às atuais representações que os sujeitos do estudo têm sobre a profissão docente. Os dados foram coletados através de um questionário semidiretivo e analisado com os recursos dos softwares ALCESTE, para análise lexical, e EVOC, para evocação livre das palavras. Os resultados revelaram que a identidade do pedagogo é compreendida como um processo de construção e reconstrução e apresenta-se como um diferencial, fruto de uma escolha profissional, e não de sacerdócio, anunciando que, embora exista um padrão social estabelecido para o exercício profissional, o pedagogo docente faz uso de sua professoralidade, na sua maneira de exercer a profissão. A contribuição pretendida por este estudo é melhor compreender as representações de pedagogos docentes nos cursos de formação de professores a respeito de sua profissão, e seu papel profissional, de forma a oferecer algumas reflexões sobre a formação em Pedagogia.

Este estudo identifica as representações sociais das professoras da Educação Infantil e do 1º ano do Ensino Fundamental sobre a Educação Infantil. Embasado nas reflexões de Moscovici (1978) e Jodelet (2004), na perspectiva da Teoria das Representações Sociais, concentra a reflexão nos discursos dos sujeitos participantes. São representações sociais forjadas no grupo e que denotam a compreensão dos seus membros sobre a realidade. Os discursos apresentados pelas professoras foram analisados pelo software ALCESTE e pelo programa EVOC. O processamento dos dados possibilitou reconhecer o espaço da Educação Infantil como um universo dinâmico de conhecimento e construção. As representações sociais apresentadas pelas professoras no transcorrer desta pesquisa nos revelam um discurso formado historicamente pelo grupo e marcado fortemente por sua formação teórica. Acompanhando o processo histórico, no qual a Educação Infantil foi gestada, verificamos algumas tendências que marcam o discurso das professoras hoje. Ao comparar a fala destes sujeitos, verifica-se que seus referenciais teóricos, sua trajetória educativa e o histórico social da Educação Infantil são fatores preponderantes para constituição de seu universo consensual e, consequentemente, das suas representações sociais. Os discursos das professoras confirmam que a história, a vivência no grupo e as teorias que embasaram sua formação contribuem para a constituição das representações sociais. Assim, as representações desvendam que as professoras pensam a Educação Infantil como o local propício para o desenvolvimento integral da criança, entremeado por atividades lúdico-pedagógicas, visando a formação do cidadão e sua inserção no universo escolar. A Educação Infantil está ancorada na ideia de desenvolvimento e as professoras objetivam tal representação na figura da árvore que cresce, da semente que germina, da escada que leva para fases superiores. Ao dialogar com os falatórios das professoras, compreendemos que as representações sociais estão presentes no seu cotidiano e compõem sua prática: falas e gestos dão conteúdo ao seu mundo.(AU0

Este estudo teve por objetivo investigar quais as representações sociais que os tutores têm, sobre a própria atuação na educação a distância, em cursos de Licenciatura. Com o propósito de analisar se o tutor se reconhece como docente e participante no processo de formação do aluno o estudo de campo teve como sujeitos tutores com formação acadêmica em licenciaturas e que atuam em cursos do mesmo nível nessa modalidade, em instituição particular de Ensino Superior da Grande São Paulo. Os caminhos percorridos para tal investigação justificam-se na trajetória formativa pessoal e nos espaços da experiência que se constroem no cotidiano dessa atividade. Um estudo sobre os modelos disponíveis na modalidade a distância no ensino superior do país, um breve histórico sobre os aspectos da EAD no Brasil e uma explanação sobre o modelo no qual esses tutores atuam, além de uma aproximação com as representações sociais da profissão docente, são abordagens presentes neste trabalho, que pretendeu contribuir para a educação aprofundando conhecimentos sobre o tutor responsável pelo acompanhamento dos alunos nos ambientes virtuais de aprendizagem, considerando as possibilidades de ampliação, de alcance e democratização da educação no país. Os Resultados demonstram que há uma tendência de ser considerada, pelo tutor, uma atuação que se confunde com a essência da profissionalidade docente, numa indicação de que é necessária uma reflexão mais aprofundada sobre a função e a atuação desses profissionais.(AU)

A presente pesquisa teve como objetivo investigar as representações sociais de ser docente do professor enfermeiro que atua no Ensino Técnico em enfermagem e cursou Pós-Graduação com ênfase pedagógica, exigido pelo MEC a partir de janeiro de 2008. A fundamentação teórica da pesquisa foi norteada pelo conceito de Representação Social enunciado por Sèrge Moscovici (1978) e mediado por Denise Jodelet (1984) e Mary Jane Spink (2004). Foram tecidas considerações sobre o ensino de enfermagem dentro do quadro da educação brasileira, evidenciando a legalização do ensino técnico no contexto socioeconômico e político do país que regulamentou o ensino técnico de enfermagem. Também foram descritas as últimas exigências feitas pelo Ministério da Educação e pelo Conselho Regional de Enfermagem sobre o exercício da docência no ensino técnico. A coleta de dados foi possível por meio de entrevistas semi-estruturadas, realizadas com 07 professores enfermeiros egressos do curso de Pós-Graduação com ênfase pedagógica. Foi utilizada a abordagem qualitativa centrada na análise de conteúdo dando voz aos sujeitos da pesquisa. Os resultados revelaram que as representações sociais sobre o ser docente da população-alvo foram ancoradas na perspectiva de transmitir os conteúdos curriculares e morais, porém, tentaram se afastar da idéia do paradigma tradicional do professor que só transmite conhecimento. Os resultados também evidenciaram que o curso de Pós-Graduação com ênfase pedagógica contribuiu com os professores enfermeiros da pesquisa para o processo de construção e reconstrução do ser docente. As representações sociais dos professores deste estudo revelaram, por último, a satisfação em ser docente atrelada à idéia de felicidade em exercer as atividades docentes, o que não deixou de lado a forte presença da profissão de enfermeiro.

This work analyses the effects of form over the emergence of new patterns of use and occupation in public spaces of housing estates designed in the 1980s and 1990s in Natal’s municipality (Brazil). We start from the premise that form acts on social process (HILLIER; HANSON, 1984), and verify how much the original spatial configuration of Parque Serrambi housing states contributed to the creation of new spatial patterns following the interventions of the people living there. The Serrambi states were built in Natal’s south based on an urbanization model following modernist’s principals and aimed to supply demands for popular dwellings. They were one of the last estates financed by the former National Dwelling Bank (BNH) and supervised by the Dwelling Cooperatives Orientation Institute (INOCOOP), materialized a spatial form different from the highrise dwelling experiences from the same period. The results were obtained through configurational analysis based on Space Syntax conceptual and methodological framework, in which space and society are viewed as interrelated. The analyses was based on represanting and quantifying spatial properties and identificatying social patterns related to the interventions. We identified that the original spatial configurations, associated to subtle changes in the states social patterns, analysed independently of non-morphological categories, gave way to the occupation patterns verrified in both Serrambi cases.

The overall objective of this research is to identify and analyze social representations of (the) teachers(the) Ranciere the Initial Training Program for Teachers in Office in Early Childhood Education - PROINFANTIL - UFRN/MEC on the teaching work, seeking to identify their constituent elements and understand the dynamics of your organization. We assume that these teachers work fundamentally, in the institutions of Early Childhood Education, with knowledge of common sense and related cultural inherent to be/do professor in the design of education guardian/giving handouts to ensure the physical integrity of children, causing a rift between the caring and educating. From this general objective, we elected as specific objectives: identify the social, economic and cultural backgrounds of these (the) teachers (sa); identify what is teaching work for them (the) as well as identify which the psychosocial implications driven by RS on teaching work that point to tensions between the training and the exercise teacher as activity profissional.Como theoretical foundation we opted for Social Representations Theory of Moscovici (2003), Jodelet (2001); Specificities of the teaching Work in Early Childhood Education: Kramer (2002; 2006); OliveiraFormosinho (2007); Zilma de Oliveira (2007), Teacher Training: Ramalho, Nunez and Galthier (2003) and Tardif and Lessard (2008), content Analysis: Bardin (2004). As methodological procedure, we chose the Central Nucleus theory, developed by Jean Claude Abric (2000). Contributed to the scope of this objective the 171 teachers (the) that concluded the Proinfantil NBs to participate of TALP with justifications. The corpus arising from evocations around the words suggested by Carlos Chagas Foundation: give classrooms, teacher, pupil and added the word Child Education, were subjected to a treatment with the aid of the EVOC software (2000), identifying the central nucleus. The results indicate the words more evoked and significant: Planning, child care, educating, and play. Indicating that for these (the) teachers (the) the teaching work in Early Childhood Education must have a systematic pedagogical to educate children. These words correspond to the specificity of being/doing teaching in Early Childhood Education. However, the data shows that it is a job with different characteristics of the teaching work in other stages of education

Spinal cord injury causes permanent disabling manifestations, affecting the anatomic integrity, bodily changes and functional limitations related to the disability state. It was aimed to analyze the social representation, stress level and experiences of fishermen victims of spinal cord injury caused by diving accident in the Northern beaches of Brazil. It is a descriptive - exploratory study with quantitative, qualitative and representational data developed i n fishermen’s villages in nine beaches of Northern shore/RN, between October 2013 to August 2014, after the approval of the Ethics Committee in Research of the Universidade Federal do Rio Grande do Norte, under the number 431.891/2013, CAAE 20818913.0.0000 .5537. The sample was composed by 44 fishermen with spinal cord injury, defined from inclusion and exclusion criteria of the participants. It was used as instrument to collect the data a semi structured interview. Quantitative data was analyzed by descrip tive statistics, showing the data through table, boxes and graphics by Microsoft Excel. Data from interviews were submitted to the software called Analyse Lexicale par Contexte d’un Ensemble de Segments de Texte (ALCESTE) using the analysis of the Social R epresentation Theory and Center Core Theory. It is shown the outcomes of the research through four articles, following the normative recommendations of the journals. Participants of the study were all male, age mean 49,6 years, elementary school (68,2%), m arried (77,3%); paraplegia sequel (50,0%). Most of them showed stress (75,0%), almost in the exhaustion stage (33,3%), prevalent insomnia symptoms (95,5%) in the last hours; hypertension (97,7%) in the last week and sexual troubles (95,5%) in the last mont h). Decompressive illness caused spinal cord injury (57,1%), occurred prevalently in low summer (75,0%), northern shore (96,4%), having as main consequences the paresthesia and pain in the upper and lower limbs (67,9%), followed by death (25,0%). Interview analysis under the understanding of Social Representation of spinal cord injury allowed the appearance of seven categories: Treatment: limitation and expectative; Spinal Cord injury: before and after; Retirement: reality yet to come; Disability: dependenc y, incapacity, vulnerability; Overcoming and autonomy; Self feelings: physics losses and new start; Life and labor: impediments, plans and changes. The center core of the representation is found in the first category by the expectative and limitation on th e treatment, meanwhile the outskirt elements are in seventh and third categories. Physics limitation for fishing activities and retirement expectative is the most outstanding of the structure. Social representation concerning spinal cord injury is found in a transaction moment between before and after with the prevented fishing activity, coping of the situation with the potential remaining. The anchoring is established in the desire for changes related to the improvements of life and health conditions exper ienced day by day through faith. This study finishes pointing out the range of the objectives, which topic is relevant for public health of fishermen. It is suggested prevention measures, promotion and health recovery of fishermen, besides safe, healthy an d worthy conditions as a compromise of social and health politics.

This piece of research aims to address the issue on the construction and reconstruction of Câmara Cascudo´s discursive representations in Mário de Andrade´s discourse. In order to describe, analyze and interpret these representations, we recur to some semantic categories from the Discourse Textual Analysis (DTA) by articulating them with other categories, notably, Grize´s Logic (1996,1997), Text Linguistics and Semantics. Therefore, the purpose is to analyze how these representations are constructed discursively, in written letters, by means of semantic categories such as referentiation, predication, modification, connection and spatial and temporal locations. In the theoretical foundation, proposals of Textual Analysis of Discourses, conceived by the linguist Jean-Michel Adam (1990, 2008a, 2011a), Text Linguistics, Semantics and Logic, focusing, especially, on the phenomenon of discursive representations, are articulated. The research approach is of qualitative nature supported by some quantitative data (OLIVEIRA, 2012); option which makes the analysis richer and comprehensive. As a hypothesis, it is presented the fact that these categories used by Mário de Andrade, in his discourse, do not only enable the (re)construction of the interlocutor´s images, discursively constructed, but they also provide a multiplicity of information and viewpoints about the RN writer´s personality. The study corpus is constituted of 20 texts written by Mário de Andrade and sent to Câmara Cascudo between 1924 and 1944, of which 35 fragments were selected and analyzed. However, it can be verified that, in the analyzed corpus, a set of discursive representations is constructed for Câmara Cascudo, from semantic categories proposed for analysis and used in Mário de Andrade´s discourse. These categories enable to construct and reconstruct the representations that emerge in the texts. Therefore, the analysis points out the construction of a set of different representations, highlighting the representation of the writer, the intellectual and the friend.

Cette recherche décrit la représentation discursive que la présidente Dilma Rousseff fait de soi-même, dans son discours devant le Congrès National, lors de la journée d’investiture, le 1/1/2011. Notre travail se situe dans le domaine théorique et méthodologique de la linguistique du texte et, plus spécialement, dans la perspective de l’Analyse Textuelle des Discours – ATD (ADAM, 2011 [2008a]), qui se définit comme « une théorie de la production co(n)textuelle de sens qui doit se fonder sur l’analyse de textes concrets ». Elle nous fournit la notion théorique et analytique de « représentation discursive », qui se focalise sur la dimension sémantique du texte. Nous nous appuyons, aussi, sur des travaux récents sur les représentations discursives, réalisés dans la recherche brésilienne sur l’ATD (RODRIGUES, PASSEGGI, SILVA NETO, 2010, 2012; RAMOS, 2011; OLIVEIRA, 2013; QUEIROZ, 2013; ZAMBLANO-OLIVEIRA, PASSEGGI, 2013). Les principales opérations sémantiques de construction de la représentation discursive utilisées dans notre travail sont la Référenciation et la Prédication. L’approche méthodologique est, en même temps, qualitative et quantitative, priorisant l’identification des occurrences, ainsi que la description détaillée de leurs valeurs sémantiques et textuelles. Les résultats de la recherche sont de trois ordres : méthodologique, théorique et descriptif-interprétatif. Méthodologique : nous proposons une approche que nous désignons comme « marquage textuel » (ou « mappage textuel ») qui permet de marquer (étiqueter) les valeurs sémantiques des formes linguistiques, permettant leur identification dans le flux textuel, c.-à-d., dans la dimension séquentiellecompositionnelle du texte. Théorique : nous introduisons la notion de « domaines de la représentation discursive » qui organisent et articulent les différents éléments qui composent la représentation discursive de la présidente. Quant aux résultats descriptifsinterprétatifs du discours de l’investiture, ils indiquent que la représentation discursive de la présidente se configure au moyen de différents domaines conceptuels, explicités par les référenciations et les prédications. Ils mettent en relief les désignations et les actions / états, aussi bien de la femme – domaine du genre – que de la présidente – domaine du rôle politique et institutionnel. La présidente se représente explicitement et avec emphase comme l’agent responsable par les actions exprimées par les prédications verbales (verbes d’action), consciente de l’importance de son rôle politique et social. Les prédications nominales signalent clairement une représentation discursive qui englobe les domaines conceptuels politique, moral, éthique, comportemental et émotionnel (forte, accueillante, pionnière, consolidatrice, infatigable, humble, engagée, démocrate, victorieuse et courageuse). Le discours d’investiture réalise, donc, des désignations positives de la présidente, lesquelles se situent dans un temps présent et prospectif – avec des perspectives de futur – comme leader politique du Brésil, avec une participation active dans la transformation du pays, tenant compte aussi de son histoire de vie, sa biographie de luttes. Ainsi, la description empirique et l’interprétation de ce discours particulier contribue à l’analyse textuelle des représentations discursives dans le discours politique brésilien contemporain. Elle soulève, aussi, des questions théoriques et méthodologiques qui nous semblent pertinentes pour le développement de cette aproche.

The reformist movements in the field of mental health have pointed battle flags, among which the prioritization of production of mental health care out of the asylum environment should be highlighted, aiming the reduction of psychiatric beds, greater control over the hospitalization, family co-participation and the rescue of the citizenship of the social players involved. With the progressive reduction of asylum beds, associated with a lot of structural problems in the health services, the occurrence of crises outside the hospital environment has been increasingly frequent, thus giving the family an important therapeutic role. In face of this scenario, there is an urgent need to understand the social construction of the care for psychiatric emergencies, identifying the meanings assigned by family members to their constituent aspects. This study seeks to answer the following research question: what are the social representations of family members about the care of psychiatric emergencies in the city of Mossoró, Rio Grande do Norte? Therefore, the aim is to analyze the social representations of family members about the care of psychiatric emergencies in the city of Mossoró, Rio Grande do Norte. This is an exploratory and descriptive study, with a mixed approach, making use of multimethods: for collection, the semi-structured interview and the Technique of Free Association of Words; for data analysis, the Thematic Analysis of Bardin and its steps was used, with the informational support of the softwares ALCESTE (Analyse Lexicale par Contexte d'un Ensemble de Segments de Texte) and Iramuteq (Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires); and the theoretical support of social representations. The study participants totaled 72, and they were selected from the following criteria: older than18 years, with degree of kinship with users suffering from some mental and behavioral disorder, and who have already witnessed a situation of crisis, rescued by the SAMU or other means and taken to the psychiatric hospital or general emergency room. Preliminary results point out: 1.Previous note of the research project with the aim to disseminate it in the scientific community and ensure the intellectual property of the work; 2.The contextual analysis of the care for emergencies in the study place. Reflection about the phenomenon provide a name to the care for the psychiatric emergencies, which is called immediate context; the technical and operational aspects that influence the care, as a specific/ general context; and mental health policies in Brazil are identified as metacontext; 3. The systematic review from randomized clinical trials in the databases PubMed, COCHRANE, LILACS, SciELO and SCIRUS, with the use of the descriptors: ‘Physical restraint’, ‘Psychiatric emergency services’, ‘Restraint’, ‘Physical and Emergency Services’, ‘Psychiatric’. Only one work met the search protocol criteria: a short-term essay that records limited results about the proportion of people who are in restraint and seclusion. It does not show statistically significant results in relation to indications, contraindications and risks of the use of physical restraint; 4. The social representations of the care for psychiatric emergencies. The study results point to the presence of five thematic categories: 1. feeling in the face of the crisis/care; 2. thoughts and perspectives about the crisis/care; 3. centrality of care in the medical- medication-hospitalization triad; 4. the thinking/acting in the face of the use of physical restraint and police force; 5. periodicity of crises. The central core of the representation is in the first category, whilst the peripheral elements are in the third and fifth categories. The contrast zone is in the second and fourth categories. The sadness is the most prominent element of the structure. The social representations about the care for psychiatric crises are at a time of transition between the hegemonic and reformist models, with the traditional aspects being predominant, but already showing peripheral and contrast elements that point to a possible change in the representational field.

The architect materializes his ideas using architectural representations that acts differently during the design process, as instrument that expresses his creatives ideas, as communication between the designer and the client, or as project documentation for its execution (DURAND, 2003). In this paper, it’s been discussed the connexion between the architectural representations and the design process, in a professional context, focusing on representation as an aid to conception. The general aim is to understand the role of architectural representations in the design process by identifying ways of appropriation of their types and resources. The investigation was developed through the theoretical and conceptual studies about the mentioned themes, and the empirical and qualitative research, with architects from the state of Rio Grande do Norte, Brazil, which was developed in two stages: the first one, by filling an electronic form, and the second one, by case studies through execution of design exercises. The results of indirect research showed that the majority of architects and urbanists believes that the way it use the types and representation resources may interfere in design concept. And, after the completion of the case studies, was showed that, motivated by different design conditions, most designers has used the representations differently, which is reflected in different design conceptions.

Analogous to sunspots and solar photospheric faculae, which visibility is modulated by stellar rotation, stellar active regions consist of cool spots and bright faculae caused by the magnetic field of the star. Such starspots are now well established as major tracers used to estimate the stellar rotation period, but their dynamic behavior may also be used to analyze other relevant phenomena such as the presence of magnetic activity and its cycles. To calculate the stellar rotation period, identify the presence of active regions and investigate if the star exhibits or not differential rotation, we apply two methods: a wavelet analysis and a spot model. The wavelet procedure is also applied here to study pulsation in order to identify specific signatures of this particular stellar variability for different types of pulsating variable stars. The wavelet transform has been used as a powerful tool for treating several problems in astrophysics. In this work, we show that the time-frequency analysis of stellar light curves using the wavelet transform is a practical tool for identifying rotation, magnetic activity, and pulsation signatures. We present the wavelet spectral composition and multiscale variations of the time series for four classes of stars: targets dominated by magnetic activity, stars with transiting planets, those with binary transits, and pulsating stars. We applied the Morlet wavelet (6th order), which offers high time and frequency resolution. By applying the wavelet transform to the signal, we obtain the wavelet local and global power spectra. The first is interpreted as energy distribution of the signal in time-frequency space, and the second is obtained by time integration of the local map. Since the wavelet transform is a useful mathematical tool for nonstationary signals, this technique applied to Kepler and CoRoT light curves allows us to clearly identify particular signatures for different phenomena. In particular, patterns were identified for the temporal evolution of the rotation period and other periodicity due to active regions affecting these light curves. In addition, a beat-pattern vii signature in the local wavelet map of pulsating stars over the entire time span was also detected. The second method is based on starspots detection during transits of an extrasolar planet orbiting its host star. As a planet eclipses its parent star, we can detect physical phenomena on the surface of the star. If a dark spot on the disk of the star is partially or totally eclipsed, the integrated stellar luminosity will increase slightly. By analyzing the transit light curve it is possible to infer the physical properties of starspots, such as size, intensity, position and temperature. By detecting the same spot on consecutive transits, it is possible to obtain additional information such as the stellar rotation period in the planetary transit latitude, differential rotation, and magnetic activity cycles. Transit observations of CoRoT-18 and Kepler-17 were used to implement this model.
