Análise comparativa entre os jornais desportivos da península ibérica e estudo do seu tratamento de imagem

Os jornais desportivos são objetos de leitura dos amantes do desporto, que todos os dias levam aos leitores as últimas notícias e informações relacionado com desporto, sendo o futebol a modalidade protagonista em todos os cenários. No âmbito do meu estágio curricular no jornal Record, achei pertinente realizar um estudo de nove jornais desportivos da Península Ibérica, fazendo a análise e a comparação entre eles. Cinco deles são nacionais (diários e semanários) e quatro são espanhóis (apenas diários). Os jornais nacionais analisados foram: Record, A Bola, O Jogo, O Sporting e O Benfica e, de entre os jornais espanhóis, analisei A Marca, As, Mundo Deportivo, e o Sport. Com esse estudo investiguei o aspeto gráfico dos jornais, como a sua capa, grelha, tipografia e o seu tratamento de imagem, assim como o seu público-alvo e a sua relação tiragem/venda.

Os valores morais dos contos de fadas em crianças com trissomia 21 - Um estudo de caso comparativo

Os Contos de Fadas contribuem para o desenvolvimento psicológico e intelectual das crianças, uma vez que despertam a curiosidade destas para novas aprendizagens, permitindo que entrem no mundo do imaginário. Os Contos permitem que as crianças criem estratégias para se posicionarem e compreenderem o mundo e os conflitos com que o homem se confronta no seu dia-a-dia. Na perspetiva de vários psicanalistas que estudam esta temática, os Contos de Fadas retratam-nos de uma forma simbólica os problemas do nosso quotidiano, ajudando as crianças a ultrapassar medos e frustrações, a entender o amor, a compreender a morte, o envelhecimento e a resolver alguns conflitos existenciais como, por exemplo, a luta entre o bem e o mal. Os Contos de Fadas exercem uma influência muito benéfica na formação da personalidade da criança. A leitura de Contos e de pequenas histórias é uma atividade enriquecedora para as crianças com Trissomia 21, uma vez que favorece os processos de compreensão, fluência e motivação para a aprendizagem. Com base nestas constatações pretende-se compreender a influência que os Contos de Fadas têm na interiorização de valores morais por parte de uma criança com Trissomia 21 quando comparada com uma criança sem qualquer Síndrome. A investigação iniciou-se com uma etapa inicial de estudo dos fundamentos teóricos da temática, através da realização de uma revisão da literatura, que resultou na identificação do problema de investigação a partir do qual se definiram os objetivos, questões de investigação e hipóteses conducentes à sua resolução. Numa segunda fase recorreu-se a uma metodologia de investigação baseada num estudo de caso que permitiu responder à questão de investigação e simultaneamente compreender a importância e pertinência que, a fantasia dos Contos de Fada tem na criatividade e imaginação da criança assim como concluir que no aspeto concreto da assimilação de valores morais apenas a criança sem qualquer Síndrome é capaz de os assimilar, ao contrário da criança com Trissomia 21 que apenas vê os Contos de Fada como mero entretenimento.

Da favela ao conjunto: a trajetória da CCPL entre o abandono, a remoção e a urbanização

O projeto elaborado no âmbito do PAC Favelas para a favela da CCPL, em Benfica, possuía um caráter peculiar que se tornou o principal objeto de análise desta tese, relacionado ao fato de que os moradores removidos seriam mantidos, em sua maioria, no mesmo terreno de suas moradias originais. Esta particularidade se contrapõe a projetos colocados em prática nas décadas de 1960 e 1970, e a planos atuais realizados na cidade do Rio de Janeiro, em que os moradores removidos são deslocados para grandes distâncias. O trabalho de campo se desenvolveu de 2009 a 2015, com o acompanhamento desde o anúncio das obras até a inauguração do conjunto habitacional. As trajetórias dos moradores mostraram que a localização da CCPL era essencial para o cotidiano dos mesmos, o que conferia importância à manutenção naquele mesmo lugar. No decorrer da pesquisa, no entanto, o processo de retirada dos moradores mostrou-se semelhante a um processo de remoção, com as inseguranças que este acarreta.

O TELETRABALHO NA UNIVERSIDADE E PROCESSOS DE COMUNICAÇÃO

O presente estudo analisa a significância e as implicações do teletrabalho na docência de nível superior no Brasil, objetivando demonstrar os benefícios e aplicações advindos desse processo para a prática professoral superior, assim como o amplo leque funcional derivado do teletrabalho aplicado no labor do professor universitário. Utilizando-se de um estudo de caso promovido junto aos docentes da Universidade Federal de Mato Grosso do SUL (UFMS), a pesquisa avalia a relação do trabalho docente com o teletrabalho e, também, os impactos, benefícios e problemas que poderão ocorrer em decorrência da implantação do teletrabalho aos docentes da UFMS. Para tanto, foi feita uma análise quantitativa e descritiva, sendo que a análise estatística descritiva serviu de base para inferências generalizadoras de natureza qualitativa. A partir dos resultados da pesquisa de campo, que utilizou como instrumento principal questionário com perguntas abertas e fechadas, o estudo conclui que o teletrabalho é uma possibilidade viável e, dentro de suas limitações, benéfica para o trabalho docente superior.

Crescimento inicial e morfologia foliar em plantas de Mimosa caesalpiniaefolia Benth. Em função do manejo microbiano, sob estresse salino

The sabiá (Mimosa caesalpiniaefolia Benth.) is an endemic species of the Caatinga biome, considered tolerant to salt and water stress. The process of salinization of soil and groundwater and surface water is one of the most important problems of environmental degradation, with its harmful effects being more pronounced in the areas of arid and semiarid regions, and rapidly growing in many parts of the globe, causing problems of the major crop yield. Organic conditioners as barnyard manure, and rice hulls can contribute to reducing the PST, possibly due to the release of CO2 and the production of organic acids during the decomposition of organic matter, and act as sources of calcium and magnesium and inhibit the availability sodium. The intimate association of mycorrhizae and beneficial to plants results in increased uptake of water and nutrients by plants, especially phosphorus, due to their low mobility in soil. The objective of this study was to evaluate the initial growth of thrush seedlings under inoculation with mycorrhizal fungi and fertilized with manure corral and irrigated with water of different salinity levels. The experiment was conducted in greenhouse conditions of vegetation on the premises of the Agricultural School of Jundiaí - UFRN, Campus Macaíba. The adopted statistical design was randomized composed of twelve treatments - three substrates (sterile soil, manure and FMA), four salinity levels (0.2, 1.5, 3.0 and 4.5 dS m-1 ) and five repetitions, totaling sixty experimental units. The results indicate that inoculation with mycorrhizal fungi own contributions to the growth of plants, especially in roots and shoots, which suggests that its application is beneficial in establishing thrush plants in natural conditions, with poor soil in P. Levels salinity caused no effects with statistical significance in plant development, indicating Sabia resistance to it.

Resiliência e apoio social em gestantes tardias

The gestation process, in general, is a very important event on a woman’s life and it brings phisical, phisiological and emotional changes, which by itself is an experience full of intense feelings. By late-aged pregnancy we mean those which occurs at the age of 35 or further. The occurance of this type of pregnancy is rising in Brasil and throughout the world, factors such as, better access to birth control resources and the search for financial stability explains the pregnancy delay. Important processes like resilience and social support can help late-aged pregnant women, in a benefical way, to adapt to the gestation process. Resilience is the capacity that a certain individual or group of individuals have to go through an adverse situation, be able to overcome it and become streghtened, transforming it in motivation for its biopsichosocial development. Social support is a complex and dinamic process that involves transactions between individuals and their social networks, meeting the social needs, promoting and complementing the personal resources that they have to face new demands. This research has the intention of raising information about the issues of late-aged pregnant women in the County of Natal- RN, the main objective was to evaluate the resilience indicators and the social support on late-aged pregnant women in the Natal-RN County. A transversal cut, correlational and descriptive research that was done with 150 lateaged pregnant women. The tools that were used were: A form with sociodemographic and gestation info, the scale of resilience and social support. An eletronic spreadsheet sofware (Excel e SPSS 21.0) was used to analize data which helped on the statistics according to its variables and the objective of this work. For the nominal variables, relative frequencies were used and for continuous the Pearson correlation and determination coefficient were used, regarding that; the sample had a normal distribution. The project fulfilled the ethnic aspects prescribed by Resolution 466/12 of the National Health Council, with a favorable decision (356.436/ 2013) of the UFRN Ethics on Research Committee. Most of the pregnant women had a low money income and education level, born in the state of Rio Grande do Norte they had an average age of 37,49 (±2,577), catholic, married, house wives, they had more than one child and were on their third trimester of pregnancy; they also had a low past abortion rate, not having planned their pregnancy, with an average of 4,22 (±2,506) pre-natal appointments, residing with an average of 3,673 (±1,397) people, having used any sort of birth control device and having high indicators of resilience and social support. The correlations kept between resilience, social support and some of the social demographics and gestation variables were considered low. Such data points out the fact that most of these women were in a stable relationship; they hadn’t had a past of abortion, they were involved with some kind of religion, they were not first pregnancy mothers, had an age on which they are not considered inexperienced mothers and even had scored high on the social support scale, these may all possibly be the most contributing factors on development and resilience building on these 35 years or more mothers. We expect that the data and information from this research may add up knowledge, actions and improvements regarding late-aged pregnant women and the pregnancy phenomena in general.

O processo de formulação do Programa Universidade para Todos: atores, coalizões e interesses

This thesis aims to analyze how the performance of the coalitions affected the formulation process of the Programa Universidade para Todos ─ Prouni. This is a program in which students from public high school, or who have been integral stock in private colleges and universities receive scholarships in private institutions, which receive tax incentives in federal taxes. As analytical framework, was used the advocacy coalition framework (ACF) framework developed by Sabatier and Jenkins-Smith (1993) that conceives the process of formulation of policies as a result of competition between groups of actors called coalitions, which are involved or interested in an issue of public policy. The actors coalesce into coalitions from beliefs, values, technical postures and positions on operational matters of public policy and act coordinately to defend their interests, interfering in the formulation of policies. With regard to methodological aspects, it is a qualitative study that used a narrative structure to present the development of Brazilian higher education and Prouni, analyzing official documents, shorthand notes of public congressional hearings and interviews with servers who worked in Ministry of Education (Brazil) time of program formulation, legislative counsel of the brazilian congress, plus the former deputy rapporteur of the Bill 3.582 / 2004, which led to Prouni. Two coalitions were identified: statist, which stood contrary to the program, and privatized, which defended its formulation. The clashes, which occurred mainly in Congress, highlight the strategies to operationalize beliefs. The two coalitions heavily used technical information and mobilization, through militancy (mobilizate troops). However, privatizing coalition acted more strongly in this case and was able to turn their beliefs into more effective action strategies. The final configuration of the Prouni was beneficial for private institutions, and showed a change in public policies related to higher education, since government support through tax breaks, before granted only to non-profit IES, became extensive also the IES with lucrative purpose.

O saber na perspectiva psicanalítica de orientação freudo-lacaniana: um estudo teórico

This work came from a research question, namely authorizing a child to learn, lifted from the care of a child of 09 years in the school service of a private university located in Natal, whose complaint referred to a learning disorder more specifically, not the formalization of reading and writing. To undertake a survey of the Lacanian psychoanalytic - Freudian literature on learning, we find the concept of knowledge as fundamental to the analysis of this issue which led us to investigate the history of its co nstruction in Freud and Lacan, with a view to shed light on their relationship to learn. This is a theoretical type of research with the proposal to revisit the concept of knowledge in the work of Freud and Lacan's teaching, in which case only served as th e trigger point of this work. We found that in both these authors, the concept of knowledge is associated to the unconscious exclusively and can be hinged to learn the way of the desire to know. It concludes that learning is a process that involves the unconscious knowledge. Consequently, learning disorders may be linked to the impossible into play in the know about the desire to find himself alienated the significant of what operates as forbidden to know when not referred only or also of teaching and / or educational aspects. This shows us that the complaints that come to the clinic can illustrate dilemmas experienced by the speaking, related to subjective questions. Deviations from the possibility of learning may indicate in these cases, a manifestation of what is singular and very impossibility of generalization when it comes to subjects. With this, also attest that the relations of the subject with knowledge effect in learning processes.

Avaliação dos efeitos tóxicos in vitro e in vivo do extrato hidroetanólico dos frutos de Genipa americana L. (Rubiaceae) em camundongos Swiss

The therapeutic use of medicinal plants has contributed since antiquity in a beneficial way for health. However, many species lacks of scientific evidence which provide basis for their use in therapeutic practice. In this context is the Genipa americana L. species (Rubiaceae), popularly known as jenipapo and used to treat syfilis, ulcer and hemorrhagic disturbs. It's also used against bruising, as tonic and as aphrodisiac. Due this species lacks toxicological studies, the aim of this study was to evaluate the toxicity in vivo (acute and sub-chronic toxicity) and in vitro (cytotoxicity) of the hydroethanolic extract from G. americana fruits. The hydroethanolic extract of G. americana fruits was prepared by maceration. A preliminary phytochemical analysis was performed to assess the presence of secondary metabolites in the extract. The cytotoxicity study of the extract (0.1, 1.0, 10, 100 and 1000 mg / 100 ul) were performed against normal cells (3T3) and tumor (786-0, HepG2 and B16), analyzed by the MTT assay. To evaluate the acute (single dose of 2000 mg / Kg) and subchronic (100, 500 and 1000 mg / kg for 30 days) toxicity Swiss mice of both sexes were used. At the end of the experiment, blood samples and organs were collected for analysis. Data between groups were compared by t test or ANOVA with Dunnett's post-test with 5% significance level. The phytochemical study of the extracts mainly indicated the presence of iridoids. Results for cytotoxicity tests showed up to 70% inhibition of B16 cell line at a dose of 1000 mg / 100 ul, and up to 29% inhibition of 786-0 at a dose of 10 ug / 100 ul. The extract did not cause death in 3T3 and HepG2 cells. During the in vivo assays, there were no animal deaths. Analysis of blood samples revealed that the animals submitted to the evaluation of acute toxicity had changes in AST and ALT, and that the animals evaluated for subchronic toxicity showed changes in the relative wet weight of the kidney and plasma urea concentration. No differences were observed between groups on histopathological evaluation of the collected organs. Despite the changes found in the in vivo toxicity tests, using the criteria described by the OECD Guidelines, it is suggested that the hydroethanolic extract of the fruits of the G. americana is classified as low toxicity. The cytotoxicity of the extract suggests that they have potential against melanoma cell lines (B16).

Métodos de avaliação nutricional para a suplementação oral com zinco em crianças pré-púberes não deficientes em zinco

Background: Zinc is an essential nutrient that is required for numerous metabolic functions, and zinc deficiency results in growth retardation, cellmediated immune dysfunction, and cognitive impairment. Objective: This study evaluated nutritional assessment methods for zinc supplementation in prepubertal nonzinc- deficient children. Design: We performed a randomised, controlled, triple-blind study. The children were divided into a control group (10% sorbitol, n = 31) and an experimental group (10 mg Zn/day, n = 31) for 3 months. Anthropometric and dietary assessments as well as bioelectrical measurements were performed in all children. Results: Our study showed (1) an increased body mass index for age and an increased phase angle in the experimental group; (2) a positive correlation between nutritional assessment parameters in both groups; (3) increased soft tissue, and mainly fat-free mass, in the body composition of the experimental group, as determined using bioelectrical impedance vector analysis; (4) increased consumption of all nutrients, including zinc, in the experimental group; and (5) an increased serum zinc concentration in both groups (p < 0.0001). Conclusions: Given that a reference for body composition analysis does not exist for intervention studies, longitudinal studies are needed to investigate vector migration during zinc supplementation. These results reinforce the importance of employing multiple techniques to assess the nutritional status of populations.
