Custo social de oportunidade na trajetória de acesso ao ensino superior: o caso dos ingressantes na UFRN nos vestibulares de 2006 a 2010

Access is a problem of higher education in Brazil that has existed since the formalization of this has occurred since the installation of the Portuguese court in Brazil in 1808. Only 10% of young people between 18 and 24 years of age attending this level of education in 2000, arriving in 2010 just 15%, far from that determined the National Education Plan in 2001, triple that percentage by the year 2010. In addition, a majority of seats of public HEIs is populated by students from the private network, especially in high-demand courses. In this context, this study aims to identify the costs related to the trajectories of students who were successful in the vestibular UFRN editions from 2006 to 2010. Presents an overview of higher education in Brazil, a brief history of vestibular, as well as new forms of access, and some of the policies to expand such access, highlighting the argument Inclusion UFRN. Focusing on the theme of the paper presents the concepts of opportunity costs and social. After collecting data through a questionnaire and consultation of databases COMPERVE was developed to search for a descriptive and analytical, with the participation of 3,995 students, of whom 1642 (41.1%) had completed secondary education in schools public, and 2,078 (52%) in private schools. The profile indicates that 90% are single, about 50% are 21 years of age, are white and female. In the course of preparation for college entrance exams, 80% chose the course during or after completion of the last year of high school, and almost 70% said they had started preparing at that time. Findings related to the costs involved with this preparation indicate that, in most cases there were school fees and disbursements and workshops, and the purchase of books and other materials, with parents primarily responsible for this cost, the amount disbursed each month was up $ 300 for 64% of respondents and only 7% of them exceeded $ 1,000, the major non-financial costs were characterized by the following resignations: job opportunities (24%) or temporary work (20%) courses of languages (26%), leisure activities (48%), leisure travel (43%), and parties and / or shows (54%). Of social investments by the government, stand out in the tax waiver scholarships for study in private institutions, grant exemption from the registration fee of vestibular, the preparatory courses UFRN, and seminars by COMPERVE / UFRN with networks of high school. From the junction of the opportunity costs (private costs) and social costs (public costs), a new concept: the social opportunity cost, which measures the combined efforts of families and government to finance the opportunity to access higher education of an individual. This concept can and should be incorporated as a strategic vector for the sake of democratic university, which reflects the social model that is sought

Utilização de medidas biométricas para predizer características da carcaça de cabritos Saanen

Foram determinadas medidas biométricas de caprinos leiteiros com o objetivo de estimar equações que permitam predizer o peso e as características da carcaça de animais sob diferentes condições nutricionais. Realizou-se um experimento em duas fases, utilizando-se 27 cabritos machos da raça Saanen em cada uma, distribuídos nos tratamentos: alimentação à vontade, 30 e 60% de restrição. O peso vivo (PV) inicial foi de 5 kg na Fase 1 e 20 kg na Fase 2, abatendo-se os animais ao atingirem 20 e 35 kg de PV, respectivamente. Foram determinadas as medidas biométricas e avaliada a condição corporal no animal vivo e, após o abate e resfriamento de 24 horas, as medidas da carcaça. Estimaram-se o peso em jejum (PJ), o peso da carcaça fria (PCF) e a compacidade da carcaça, em função das medidas biométricas. O perímetro torácico e o comprimento corporal foram as medidas biométricas que apresentaram melhor ajuste para estimar o PJ, o PCF e a compacidade da carcaça e, por isso, são recomendados, por serem precisos, práticos e de fácil execução.

Uma abordagem histórica para o ensino do princípio da inércia

Placed in the field of Didactic of Science, this paper proposes an approach to the introduction of the History of Science in science education, at high school level. It was designed and implemented a series of activities regarding the history of the Principle of Inertia. The aim of this approach was to give more meaning to scientific education, while opening new avenues for a better understanding of the processes of construction of scientific knowledge. The preparation of the activities involved a study of the historical development of the concept of motion, from the Aristotelian physics through physical movement concepts at medieval period, from Galileo, Gassendi, Descartes, until the first law of Newton. The strategy of teaching was applied to three classes of high school (night period) of a state public school at the city of Natal (RN). The results indicated the difficulty of overcoming alternative conceptions about movement by students. Nevertheless, we consider that the implementation of this strategy of teaching both represented gains for the learning of students, and contributed to the resizing of pedagogical practices of the teacher-researcher

A dialética do amor em pigmaleão, de G. B. Shaw.

Pygmalion (1913), by George Bernard Shaw (1856-1950), has many studies in literary criticism. However, this study brings a new interpretation to Shaw s play based on Harold Bloom s theory and methodology, that is, the anxiety of influence and the dialectic of revisionism. Through the analysis of poetic influence and the dialectic of love, we can see that Pygmalion represents an apophrades in relation to William Shakespeare s The Taming of the Shrew (1593) and Ovid s myth of Pygmalion and Galatea in Metamorphosis (c. 14), which creates a family romance between the three stories. Shaw s play surpasses The Taming of the Shrew when it shows the possibility of the relation between this parent poem and Ovid s myth, which it is also its parent poem, and because it represents a strong misreading of Shakespeare s play as well as of Ovid s myth.

Performances da escrita

Este artigo aponta as características de uma escrita performática a partir do cruzamento entre o discurso ficcional, o discurso filosófico e o discurso crítico como formas equivalentes de experiência. Busca-se compreender os diferentes contextos em que a performance, como campo de experimentação, invade a área dos estudos literários, produzindo efeitos de deslocamento do cânone e seus modos de legitimidade, bem como visa a problematizar os lugares determinados do emissor e do receptor do texto; do artista, do filósofo e do crítico

Fragmentos da presença do pensamento idealista na história da construção das ciências da natureza

O propósito deste trabalho é estabelecer o caminho percorrido pelo idealismo em sua participação na construção das Ciências da Natureza desde a antigüidade até o final do século XX. Para os pensadores antigos, o mundo físico era governado pela idéia, e o modo de apreendê-la era por meio da contemplação da alma ou da observação e da lógica. Na escolástica essa idéia é Deus. Na renascença, Deus se torna matemático. em Galileu a Matemática do mundo é entendida pela experimentação. Para Descartes o mundo é mecânico e entendido por hipóteses dedutivas. Newton enxerga o mundo mecânico construído e corrigido pelo Deus geômetra e entendido pela observação e experimentação. Os empiristas retiram a idéia do universo e a colocam no espírito humano. em Kant as regras que organizam as idéias na mente também organizam o mundo mecânico. em Hegel o real só é real porque é racional, e essa racionalidade vem de Deus, que transforma o mundo natural e atinge o espírito humano. Os pensadores, influenciados por Hegel, percebem a incapacidade das leis da mecânica explicarem as leis da vida. Comte e Bergson procuram, de forma diferente, submeter às leis da Física às leis das ciências da vida. O universo mecanicista é absorvido pelo determinismo relativista e pelo probabilismo quântico. A linguagem da lógica se associa ao empirismo na descrição da ciência procurando retirar dela o idealismo e a metafísica e, após um período de florescimento, acaba não tendo sucesso. A dificuldade da apreensão do real volta a ser o problema da ciência no final do século XX, e a procura de uma possível solução reaproxima a ciência do idealismo.

Um esboço da história do conceito de trabalho virtual e suas aplicações

Neste trabalho abordamos a questão concernente à origem do princípio de trabalho virtual e sua consolidação como um dos conceitos fundamentais no estudo da mecânica analítica e, em particular, dos sistemas em equilíbrio estático. Ênfase foi dada às contribuições seminais de Stevin, Galileu e, sobretudo, as de d'Alembert e Lagrange, no tocante ao conceito de trabalho virtual. Além disso, faz-se um comentário geral sobre vínculos holônomos e deslocamento virtual. Alguns exemplos de emprego da equação de d'Alembert-Lagrange são apresentados, para mostrar como o princípio de trabalho virtual pode ser adequadamente aplicado.

Artificial reefs and their effects on fish assemblages in a Brazilian reservoir and Tailrace

In this paper, we evaluate the effects of artificial reefs on fish assemblages in a hypereutrophic reservoir and in the lotic zone immediately below dam. Fish diversity was highest in the lotic zone relative to the reservoir. We also found an inverse relationship between diversity and distance from the river margin. Catches near the artificial reefs were more diverse than in control areas. A seasonal effect, possibly caused by variation in temperature, was significant in all comparisons. We argue that, in a scale of local effects, the ecological function of these structures would be similar to refuges.

Factors affecting fish diversity and abundance in drying ponds and lagoons in the upper Paraná River basin, Brazil

Monthly samples were taken from April 1992 to March 1993 of fish assemblages present in six permanent lagoons and four ponds, fragmented from them during the drought period and during the terminal phases of desiccation, to evaluate changes in their diversity, abundance and dominance. Their relationships with hydrological and environment conditions were examined. A total of 63 fish species were identified. Species composition and abiotic factors were heterogeneous among the different water bodies. The proportion of piscivores and oxygen concentration were the determining factors for structuring the assemblages. The impact of piscivory upon fish diversity was neutral at the beginning and negative at the end of the dry season. In the terminal phase of desiccation, diversity was higher in ponds that contained a moderate proportion of piscivores than in these containing a higher proportion.
