A Concordância verbal e suas repercussões avaliativas nas redações de vestibular

This paper attempts to quantify the occurrences of verb agreement, as well as evaluative repercussions on a sample of one hundred and eight essays compiled by candidates entering the São Paulo State University- UNESP in 2006 through an annual entrance exam conducted by the Foundation and applied for Vestibular the Unesp - VUNESP in November 2005. Our reflections are observing about the possible relationships between the performances obtained in newsrooms observed (high, medium and low) and precepts found in the rules established by normative grammars. Our study is based on theoretical and methodological framework of variationist sociolinguistics and search through the quantification of data, discuss the factors that influence verb agreement in the corpus analyzed. Our results show not only a high index of cases of verbal agreement (standard variant) in the three types of essays analyzed, as well as cases of overcorrection that may be explained by the misapplication of the rules of agreement

O acesso à universidade pública no Brasil e a questão social: uma análise dos dados do relatório do vestibular da Universidade Estadual Paulista Julio Mesquita Filho UNESP

This work has as a central concern in analyze the causes of the still limited access of young Brazilians to public higher education in socioeconomic and cultural.In Brazil, onçy 14,4% of the young between 18 and 24 years old attend this educational level.If we consider that the public university offer just 1/4 of the vacancies, can be affirmed that this institutions are not able to attend neither 4% of the young between 18 and 24.Brazil shows,in this level of education,a lower access that most of its neighbors: Argentina(40%), Venezuela(26%), Chile(20%),Bolivia(20%).In this work were analyzed the data reports of entrance exam of Universidade Estadual Paulista (Unesp) entre 2004 e 2009,prepared by Fundaçao para o Vestibular da Universidade Estadual Paulista(Vunesp). In this analysis,can be noted the influence of some aspects socioeconomic and cultural related to possibilities os the young acces to public univercity. Stand out among these: family income,the possibility to dadicate only to studies and attend preparatory courses,as well as the parents level of education.

Trajetória social de alunos de um curso pré-vestibular popular

The aim of the research that originated this article was the analysis of the social trajectory of students from a public preparatory course and the verification of their expectations about higher education. Data collection was based on a questionnaire with open and closed-ended questions and a semi-structured interview, based on the models used by Muzzetti (1997). Data were analyzed by the elaboration of thematic charts. Based on the researches conducted by Pierre Bourdieu (1997, 2007), this research concluded that the students understand that schooling is, besides being a viable alternative in the search for social ascension, the redeeming of social ills. Profession choice based on natural talent or divine gift generate expectations which attest the lack of knowledge about the school system by students and their parents, which is reinforced by the belief in opportunity equality.

Da invenção do vestibular aos cursinhos populares: um desafio para a orientação profissional

This article is based on the sociological and historical approach of the origin of the university entrance exams in Brazil and shows the preparatory courses (preps) expanding simultaneously as a strategy of the lower and middle classes to get their children into university. Thus, the paradox of an antipedagogical practice becomes an essential condition for students to have access to prestigious university courses, what justifi es the historical movement by the lower and middle classes to appropriate this practice.. We propose that measures are taken to improve the results of important affi rmative actions that aim to enable students to enter university, as well as highlight Professional Guidance as a necessary resource which constitutes a new challenge in this fi eld of action.

Evasão no cursinho pré-vestibular da FCA/UNESP: a interpretação do aluno evadido

The popular cram schools are voluntary initiatives aimed at people who are not able to afford the cost of private cram schools. The FCA popular cram school integrates a large project from UNESP, which has 30 cram school distributed throughout Sao Paulo State and located in different University units. Among the problems found in popular cram schools, school evasion, characterized when the student quits the course and is very common in this context. Thus, the aim of this work was to identify the profile of the drop out student from the FCA cram school as well as to know the reasons that led them to leave. The survey was conducted in two phases: 1) students´ profile when entering the cram school, through a structured questionnaire, 2) semi-structured interviews by telephone with all the drop out students, trying to identify the reasons that led them to abandon the course. The statistical analysis used was descriptive. Among the reasons that led them to leave, it was found that 65% of the students attributed this attitude to external factors as opposed to 35% who put the internal factors as the decisive reason of their departure. Some of the factors that could be attest for the FCA cram school evasion are: primarily, the heterogeneity of students and their need to work in order to support themselves and their family; students lack of motivation about a long-term success; lack of family encouragement; the difficulty of the student to establish significant personal links with cram school staff and the fact that the professors are mostly undergraduate students from different courses in different areas, with little didactic-pedagogic preparation and inability to work with students' heterogeneity.

Redações de vestibular: a materialização da relação entre leitura e escrita e o diálogo com a coletânea

This work aims to understand in what way the relation between reading and writing works in the writing tests of two major entrance exams from the state of São Paulo, used as a form of admission to two great universities - UNICAMP and UNESP -, as well as analyze in what way the candidates who got grades above the average dialogue with the collection of texts which is offered in the writing test proposal. In order to found these questions on theoretical material, we have done some reading of the Bakhtin circle to understand the questions that are related to the dialogism and had support in other linguists to solidify our interpretations and analyses. We understood, after the studies and analyses, that the materialization of the relation between reading and writing is present in the majority of the texts used as the corpus of our work and that the dialogue with the collection of texts is very appreciated and present in the texts that got the highest grades or were considered above the average. The writing test has always had an unique importance in the selection processes to admission to undergraduate courses, and we believe that the analyses that were proposed here can help students and teachers to better understand the valuation which is attributed to the relation between reading and writing and the use of the collection of texts in the elaboration of a text in the entrance exams

A new method to analyze the subjective visual vertical in patients with bilateral vestibular dysfunction

OBJECTIVE: The aim of this study was to assess the subjective visual vertical in patients with bilateral vestibular dysfunction and to propose a new method to analyze subjective visual vertical data in these patients. METHODS: Static subjective visual vertical tests were performed in 40 subjects split into two groups. Group A consisted of 20 healthy volunteers, and Group B consisted of 20 patients with bilateral vestibular dysfunction. Each patient performed six measurements of the subjective visual vertical test, and the mean values were calculated and analyzed. RESULTS: Analyses of the numerical values of subjective visual vertical deviations (the conventional method of analysis) showed that the mean deviation was 0.326 +/- 1.13 degrees in Group A and 0.301 +/- 1.87 degrees in Group B. However, by analyzing the absolute values of the subjective visual vertical (the new method of analysis proposed), the mean deviation became 1.35 +/- 0.48 degrees in Group A and 2.152 +/- 0.93 degrees in Group B. The difference in subjective visual vertical deviations between groups was statistically significant (p < 0.05) only when the absolute values and the range of deviations were considered. CONCLUSION: An analysis of the absolute values of the subjective visual vertical more accurately reflected the visual vertical misperception in patients with bilateral vestibular dysfunction.

Dynamic Viscosity of Implantable Autologous Materials Into the Vocal Fold

Objective. To compare the dynamic viscosity (DV) of superficial layer of temporalis fascia (SLTF) with that of other biological tissues traditionally used for vocal fold implants to treat vocal fold rigidity. Study Design. Experimental. Method. Measurement of DV of samples of SLTF, deep layer of temporalis fascia (DLTF), and abdominal fat of 12 cadavers. Results. DV values of the different samples were presented in the following increasing order: SLTF, DLTF, and abdominal fat. There was statistical difference between the samples. Conclusion. DV of SLTF is lower than of other tissues tested.

Static postural balance study in patients with vestibular disorders using a three dimensional eletromagnetic sensor system

The vestibular-ocular reflex assessment is important, but not enough. Tridimensional electromagnetic sensor systems represent a new method to assess posturography. Aim: To assess body sway in healthy subjects who had positive Dix Hallpike and Epley maneuvers and with other vestibular dysfunctions by means of a three-dimensional system. Study design: Prospective. Materials and Methods: We had 23 healthy women, 15 with peripheral vestibular dysfunction found upon caloric test and 10 with positive Epley and Dix Hallpike maneuvers. All tests performed in the following positions: open and closed eyes on stable and unstable surfaces. Results: With the Eyes Open and on a stable surface, p < 0.01 between the control group and the one with peripheral vestibular dysfunction in all variables, except the a-p maximum, full speed and mediolateral trajectory velocity, which had a p < 0.01 between the group with vestibular dysfunction and controls in all positions. The group with positive Epley and Dix Hallpike maneuvers had p < 0.01 at full speed and in its components in the x and y in positions with open and eyes closed on an unstable surface. Conclusion: The tridimensional electromagnetic sensors system was able to generate reliable information about body sway in the study volunteers.

Effects of Hepatocyte Growth Factor Injection and Reinjection on Healing in the Rabbit Vocal Fold

Objectives/Hypothesis. Hepatocyte growth factor (HGF) is a multifunctional polypeptide that plays various roles in embryogenesis and tissue regeneration and exhibits marked antifibrotic activity. The present study sought to assess the effects of HGF injection and reinjection coinciding with its peak of activity on collagen density, vessel density, inflammatory reaction in the lamina propria, and mean epithelial thickness in the injured rabbit vocal fold. Study Design. Prospective, controlled, experimental animal study. Methods. Fourteen rabbits were subdivided into two groups and underwent injury of the vocal folds. Immediately after injury, animals in group 1 received HGF injections into the right vocal fold (RVF), whereas those in group 2 received bilateral HGF injections and a single reinjection into the RVF 10 days after the first, to coincide with the peak of HGF activity. The left vocal folds (LVFs) served as controls in both groups. Histological assessment of laryngeal specimens was performed at 30 and 40 days, respectively. Results. In both groups, collagen density was lower in the right (treated) vocal folds than in the left (control) folds (P = 0.018). Vessel density was higher in the RVFs in group 2 (P = 0.018). Differences were found in mean epithelial thickness and inflammatory reaction in the lamina propria but did not reach statistical significance. Conclusions. In the scarred rabbit vocal fold, HGF injection is associated with decreased collagen density in the lamina propria, whereas reinjection after 10 days produces decreased collagen density and higher vessel density.
