Formal education, understood by the gradual process that occurs at school, aims at learning and systematic knowledge is of great interest to society as it benefits its individuals and leads to many positive effects, such as increased productivity and welfare (Johnes, Johnes, 2007). Understanding what influences the educational outcome is as important as the result itself, because lets you manage these variables in order to obtain a better student performance. This work uses the data envelopment analysis (DEA) to compare the efficiency of Rio Grande do Norte schools. In this nonparametric method, an efficiency frontier was construct from the best schools that use the inputs set to generate educational products. Therefore, the data used were obtain by Test Brazil and year 2011 School Census to state and municipal schools of Rio Grande do Norte. Some of the variables considered as inputs and outputs have been obtain directly these bases - the other two were prepared, using the Item Response Theory (IRT) - they are the socioeconomic and school infrastructure indices. As a first step, we compared several DEA models, with changes of input variables. Then was chose the non-discretionary model for which was deep the analysis of results. The results showed that only seven schools were efficient in the 5th and 9th grades simultaneously; there were no significant differences between the efficiency of municipal and state schools; and there were no differences between large and small schools. Analyzing the municipalities, Mossoró excelled in both years with the highest proportion of efficient schools. Finally, the study suggests that using the projections provided by the DEA method, the most inefficient schools would be able to achieve the goal IDEB in 2011, in other words, it is possible to improve the education of significant state taking the efficient schools as a basis for too much.

Located on the western edge of the Brazilian northeast, the Parnaíba Basin is an intra cratonic basin with oil production. This study aims at understanding its genesis and evolution, using aeromagnetic and gravity data. We used the spectral analysis of aeromagnetic data to map the depth to the bottom of the magnetic sources in order to assimilate this depth with the depth of the Curie isotherm, and infer the geothermal gradient. Using the spectral analysis technique, we succeeded in mapping the surface of the depth to the bottom of magnetic sources (SBFM), which marks the depth that occur magnetization. In the Parnaíba Basin the SBFM presented depths around -20,5 and -28,5 , which was consistent with an inversion of the same dataset using the technique of Magnetization Vector Inversion (MVI). Furthermore, SBFM topography correlates well with Moho depth, which was estimated from satellite gravimetric data from the GOCE mission (Gravity Field and Steady-State Ocean Circulation Explorer). Assuming that SBFM coincides with the Curie isotherm of magnetite (ICM), defined as the surface at which magnetite ( ) looses its ferromagnetic properties, it was possible to estimate the geothermal gradient. The geothermal gradient in the basin showed values between 19.2 and 26.5 , allowing to estimate the heat flow for the Parnaíba basin after assuming a conductivity of 2.69 . The resulting heat flow values ranged between 51.6 and 71.3 , which is consistent with values found in other works throughout the South American continent. Lithospheric thickness using an empirical relationship, finding values between -65.8 and -89.2 . We propose that thermal structure of Parnaíba basin is influenced by a deep thermal anomaly. This anomaly has heated the lithosphere beneath the basin and has resulted in relatively thin values for the lithospheric thickness and relatively high surface heat flow values. The origin of the anomaly is not clear, but the correlation between Curie depth and Moho topography, suggests that tectonic extension processes could have played a role.

INTRODUCTION: The pregnancy and childbirth cause many changes in a woman's life, whether physical, hormonal, emotional or social. Such changes may affect the postural balance and the quality of life of women in pregnancy and may persist after delivery. To analyze changes in postural balance and quality of life in women in pregnancy and postpartum. METHODS: This study consisted of 47 women participants of the Course for Pregnant Women of the Department of Physical Therapy at UFRN, evaluated during pregnancy (2° or 3° trimester) and in the period 1-8 months postpartum. In all participants was evaluated the postural balance, the Balance Master® in five specific tests: (1) Modified Clinical Test of Sensory Interaction on Balance-MCTSIB; (2) Rhythmic Weight Shift Test - RWS (3) unilateral stance - US, (4) Sit to Stand - STS, and (5) Walk Across - WA. The quality of life (QoL) was assessed by applying the Quality Score of life Ferrans & Powers (IQVFP), both during pregnancy and in the postpartum period. For statistical analysis we used the Statistical Package for Social Sciences software for Personal Computer- SPSS (version 20.0), applying the tests: Shapiro-Wilk to assess the normality of the data; Chi-square to analyze the frequency of postural balance changes in the two groups of pregnancy and postpartum in both groups; McNemar test to analyze balance disorders frequency of related samples in the two time points; to compare the behavior of postural balance during pregnancy and postpartum, and to compare the QoL between the periods, we used the Wilcoxon test; and yet, the MannWhitney test to compare the QoL scores in the two groups of pregnancy and postpartum in both groups. We adopted p-value <0.05. RESULTS: Comparing the postural balance during pregnancy and postpartum in MSTSIB test has statistical difference in unstable surface with closed eyes (p=0.001) and in the US test, the speed of oscillation with right leg with eyes closed (p=0,03). Quality of life, there was statistical difference between the scores only among postpartum groups, the family domain (p=0.03); and to comparing pregnancy and postpartum in domain health and operation (p=0.02) and the Socioeconomic domain (p=0.01). CONCLUSIONS: It was observed that the balance changes present during pregnancy persist postpartum, and the quality of life is considered good by women, both during pregnancy and postpartum.

This research analyzed the discourse of Brazilian transmen in relation to (un) pathologizing of identity (trans). Therefore, it seeks to analyze the perception of the meanings attributed by Brazilian transmen to their experiences within the context in which their experience is considered a psychiatric disorder, which can be (or not) be diagnosed by doctors and psychologists. Whereby, obtaining such permissions becomes a necessity to perform bodily changes, as well as referrals for modifications of civil documentation. The methodology used was discourse analysis and research techniques were semi-structured interviews and systematic observation of the meetings of Cartografias Trans group, psychotherapeutic care group of transpeople to the Centro de pesquisa e atendimento à travestis e transexuais - CPATT in Curitiba , Paraná. The theoretical framework of the research suppoted mainly, but not only, in the studies proposed by queer theory. In this sense the research found by entering the field and analyzing the data brought, among other things, the existence of a strategic discourse by Brazilian transmen toward depathologization of their identities, manifested mainly on the notion of to have the identity (trans) pathologized does not make them sick.

Camu-camu (Myrciaria dubia H.B.K. (McVaugh)) is a native Amazon fruit, recognized worldwide as one of the main natural sources of ascorbic acid. Due to its great acidity, this fruit is generally consumed after processing into juice or as ingredient in food preparations. As a co-product of the camu-camu processing, a significant amount of agroindustrial residue is generated. Despite the studies showing the bioactive value and biological potential of the fruit, few studies have approached the possible processing techniques, transformation and preservation of camu-camu fruits and its agroindustrial pomace. Therefore, the present work has the objective of evaluating two different drying processes applied to camu-camu pomace (peel and seeds with residual pulp), freeze drying and hot air drying, in order to obtain a functional fruit product. This thesis was divided into three stages: the first one shows the studies related to the freeze drying and hot air drying, where we demonstrated the impact of the selected drying techniques on the bioactive components of camu-camu, taking the fresh pomace as the control group. Among the investigated conditions, the groups obtained at 50ºC and 4 m/s (SC50) and 80ºC and 6 m/s (SC80) were selected as for further studies, based on their ascorbic acid final content and Folin-Ciocalteau reducing capacity. In addition to SC50 and SC80, the fresh pomace (RF) and freeze dried (RL) samples were also evaluated in these further stages of the research. Overall, the results show higher bioactive concentration in the RF samples, followed by RL, SC50 and SC80. On the second step of the research, the antioxidant, antimicrobial and antienzymatic activities were evaluated and the same tendency was observed. It was also reported, for the first time in the literature, the presence of syringic acid in dried camu-camu pomace. In the third and final stage of the research, it was investigated the effect of dried camu-camu on aging and neuroprotective disorders, using the in vivo model C.elegans. It was observed that camu-camu extracts were able to modulate important signaling genes relevant to thermal and oxidative stresses (p < 0.05). The polar acid, polar basic and polar neutral fractions obtained from the low molecular extracts of SC50 were able to extend the lifespan of wild type N2 C. elegans in 20% and 13% (p < 0.001). Results also showed that the paralysis induced by the β1-42 amyloid was significantly (p < 0.0001) retarded in CL4176 worms. Similarly, the camu-camu extracts attenuated the dopaminergic induction associated to Parkinson’s disease. Finally, a global analysis of the data presented here reveal that the camu-camu pomace, a co-product obtained from the industrial processing of a native Brazilian fruit, is a relevant natural source of health relevant compounds. This thesis, shows for the first time, the multifunctionality of camu-camu pomace, a natural resource still underexploited for scientific, commercial and technological purposes.

In Brazil, the National Agency of Electric Energy (ANEEL) represents the energy regulator. The rates review have been one of its main tasks, which establish a pricing practice at a level to cover the efficient operating costs and also the appropriate return of the distributors investments. The changes in the procedures to redefine the efficient costs and the several studies on the methodologies employed to regulate this segment denote the challenge faced by regulators about the best methodological strategy to be employed. In this context, this research aims to propose a benchmarking evaluation applied to the national regulation system in the establishment of efficient operating costs of electricity distribution utilities. The model is formulated to promote the electricity market development, partnering with government policies ant to society benefit. To conduct this research, an integration of Data Envelopment Analysis (DEA) with the Stochastic Frontier Analysis (SFA) is adopted in a three stages procedure to correct the efficiency in terms of environmental effects: (i) evaluation by means of DEA to measure operating costs slacks of the utilities, in which environmental variables are omitted; (ii) The slacks calculated in the first stage are regressed on a set of environmental variables by means of SFA and operating costs are adjusted to account the environmental impact and statistical noise effects; and, (iii) reassess the performance of the electric power distribution utilities by means of DEA. Based on this methodology it is possible to obtain a performance evaluation exclusively expressed in terms of management efficiency, in which the operating environment and statistical noise effects are controlled.

The maned wolf (Chrysocyon brachyurus Illiger 1815) is the biggest canid in South America and it is considered a “near threatened” species by IUCN. Because of its nocturnal, territorial and solitary habits, there are still many understudied aspects of their behavior in natural environments, including acoustic communication. In its vocal repertoire, the wolf presents a longdistance call named “roar-bark” which, according to literature, functions for spacing maintenance between individuals and/or communication between members of the reproductive pair inside the territory. In this context, this study aimed: 1) to compare four methods for detecting maned wolf’s roar-barks in recordings made in a natural environment, in order to elect the most efficient one for our project; 2) to understand the night emission pattern of these vocalizations, verifying possible weather and moon phases influences in roarbark’s emission rates; and 3) to test Passive Acoustic Monitoring as a tool to identify the presence of maned wolves in a natural environment. The study area was the Serra da Canastra National Park (Minas Gerais, Brazil), where autonomous recorders were used for sound acquisition, recording all night (from 06pm to 06am) during five days in December/2013 and every day from April to July/2014. Roar-barks’ detection methods were tested and compared regarding time needed to analyze files, number of false positives and number of correctly identified calls. The mixed method (XBAT + manual) was the most efficient one, finding 100% of vocalizations in almost half of the time the manual method did, being chosen for our data analysis. By studying roarbarks’ temporal variation we verified that the wolves vocalize more in the early hours of the evening, suggesting an important social function for those calls at the beginning of its period of most intense activity. Average wind speed negatively influenced vocalization rate, which may indicate lower sound reception of recorders or a change in behavioral patterns of wolves in high speed wind conditions. A better understanding of seasonal variation of maned wolves’ vocal activity is required, but our study already shows that it is possible to detect behavioral patterns of wild animals only by sound, validating PAM as a tool in this species’ conservation.

BACKGROUND: Among the wide range of skills displayed by a medical doctor is undoubtedly the need to use cohesive and well grounded clinical reasoning in order for medical care to be indeed effective. It is in this respect that conceptual maps emerge; these are a methodological innovation that allows a comprehensive, panoramic and associative outlook of theoretical content, making it more practical and applicable to the reality of clinical observation. Promoting learning, learning resources and a feedback system between professor and students, as well as assessing and monitoring the performance of students during their academic training, are the main features of this tool. OBJETIVE: Assess the use of conceptual maps as a teaching-learning tool in the training of undergraduate medical students at Universidade Federal do Rio Grande do Norte (UFRN). METHODOLOGY: Interventional, randomized, cross-sectional study conducted with students from the 3rd and 5th periods of the medical course at UFRN, during the second semester of 2014, totaling 86 participants, divided into two groups: GI (intervention – clinical case resolution with a conceptual map) and GII (control – clinical case resolution without a conceptual map) in each period. RESULTS: The use of conceptual maps to teach liver failure syndrome resulted in a statistically significant cognitive gain for G1 students from the 5th period (GI: 6.8±1.6 and 8.0±1.5, p = 0.024; GII: 7.2±2.1 and 8.0±1.7, p = 0.125, pre and post-intermediate means, respectively), a result not observed in the period 3rd (GI: 7.7±1.3 and 8.0±1.4, p = 0.501; GII: 6.7±1.8 and 7.8±1.8; p=0.068, pre and post-intermediate means, respectively). Students in the 3 rd period gave better responses to the first clinical case, with a larger number of suitable concepts and crosslinks, when they used conceptual maps (GI: 91.3±13.15 and GII: 64.84±22.84, p=0,002). Students in the 5th period exhibited better clinical reasoning and more complete responses using the tool (p=0,01). Most of the students were not aware of the tool (53.8% from the 3rd period and 65.3% from the 5th period). Among those who knew about conceptual maps, most (59.3%) had only used them during high school, 14.8% had never used them and only seven students (25.9%) used them during the medical course. Analysis of open responses, obtained in process assessment showed clear satisfaction and enthusiasm with learning about the new tool, and frequent suggestions to use it at other moments in the course. Assessment of learning profile, using the VARK questionnaire, showed that most students from both periods exhibited a multimodal style. CONCLUSION: Despite their scant knowledge regarding the tool, good acceptability and understanding was observed in the study participants. The conceptual maps allowed cognitive gains, better responses and clinical reasoning in teaching liver failure syndrome to 5th period students.

Teacher identity is a subject of study and discussion in the academic world whichhas become an object of attention of researchaddressing teaching and teacher formation. Life history, initial and continuing formation, the meaning of teaching to the teacher, and also pedagogical practice are all contributing factors to teachers’ professional identity. The present study is a proposal developed in the research field of Educational Knowledge and Practice, and its main focus lies in university teaching. Higher education teaching in the context of a dance course, and the issues and challenges of constructing teachers’ professional identity are presented. Thus, my main questions were: what is the teaching path followed by newly hired dance teachers in the Federal University of Uberlândia? How is teaching identity developed in these new teachers’ professional socialization process? What kind of educational knowledge is (re)produced and mobilized by teachers when they join university teaching? In order to answer these questions, my objectives are: to analyze the teaching path of the newly hired dance teachers of the Federal University of Uberlândia; to investigate how their teaching identity is built within their professional socialization process; and identify the kinds of educational knowledge they (re)produce and mobilize as soon as they become university teachers. The present research comprises a qualitative data analysis from previous studies on the subject, having as starting point relevant bibliographic research, followed by an identification questionnaire and an interview conducted with the newly hired dance teachers. The construction of teaching identity is related to objective and subjective conditions involving a teaching job and how the teacher perceives this identity as constantly evolving. Hence I understand the importance of personal and institutional incentives to prepare studies which raise or problematize issues specific to this area, contributing to extend the debate over higher education professionals’ formation, in particular that of dance course teachers on national scope.

Objetivo: Avaliar o efeito da nicotina na cicatrização da camada musculoaponeurótica da parede abdominal. Métodos: Estudo experimental em que foram usados 16 ratos da raça Wistar pesando em média 210±8g, separados aleatoriamente em 2 grupos de 8. Nos animais do grupo A foi implantado disco de nicotina (Nicotinel Ò) na dose de 5mg/Kg de peso/dia no subcutâneo da região dorsal, trocado a cada dois dias, a partir do 5º dia antes da operação em que foi feita laparotomia mediana de 5 cm, até o 10o dia de observação. No grupo B (controle) foram usados discos de celulose com o mesmo diâmetro. Tubo de silicone multiperfurado foi implantado no subcutâneo a 1cm da lesão da parede abdominal. A camada musculoaponeurótica e a pele foram suturadas com fio de nylon 5-0. No 10º dia pós-operatório foi colhido 1ml de líquido seroso do tubo de silicone por punção percutânea para dosagem de pO2 e os animais receberam dose letal de anestésico. Foi ressecado um segmento da camada musculoaponeurótica com 2cm de largura para tensiometria, em seguida processado e corado em HE e tricrômico de Masson para análise quantitativa dos dados histopatológicos em sistema digitalizado. A análise estatística foi feita pelo ANOVA e teste Newman-Keuls, com significância 0,05. Resultados: No grupo A a pO2 do líquido tecidual atingiu o valor 17,75±3,4 mmHg e no grupo B (controle) a pO2 = 40,75±6,4 mmHg (p<0,01). A resistência à tensão apresentou o valor de 728,5±161,75gf no grupo A e 1241,6±232gf no grupo de controle (p<0,01), coincidindo com os achados da pO2. A densidade média dos elementos histopatológicos estudados foi de 105±17,1 nos animais do grupo A e 146,2±8,8 no grupo B (p<0,01). Conclusão: após avaliação da pO2 tecidual, tensiometria e histopatologia, concluiu-se que a nicotina por via subcutânea exerce efeito deletério sobre a cicatrização de lesões da parede abdominal de ratos

Em Portugal, cerca de duas centenas de organizações estão empenhadas a criar e implementar Planos para a igualdade de homens e mulheres. Entre elas estão empresas públicas e privadas, autarquias, associações empresariais, organizações do setor terciário, associações de desenvolvimento, universidades, ministérios e outros departamentos governativos. A pesquisa que aqui se expõe inscreveu-se num projeto mais amplo de diagnóstico em realização na Câmara Municipal da Lousã, que se encontra a promover um Plano Municipal para a Igualdade. Nesse âmbito mostrou-se necessário fazer um diagnóstico interno à organização com uma perspetiva de género, quer em termos de desigualdades de género na composição e situação dos seus efetivos quer de forma a conhecer as representações das pessoas que trabalham na autarquia, em torno do fenómeno da (des)igualdade de mulheres e homens. Para a sua realização foi feita análise estatística a dados fornecidos pela organização, e aplicou-se um inquérito por questionário ao pessoal ao serviço da autarquia. Concluiu-se que estamos na presença do fenómeno da desigualdade em função do sexo na estrutura da organização traduzida pela segregação ocupacional e segregação vertical, sendo os homens que apresentam os maiores níveis de antiguidade, que justificarão, de certa forma, as disparidades salariais existentes. Confirmamos uma dualidade entre o ideal de mulher como mãe e dona-de-casa e o de mulher como pessoa independente, especialmente quando são evocadas as consequências da sua atividade profissional sobre os/as filhos/as e a vida familiar. O papel de cuidar surge assim como o obstáculo a conceções menos tradicionalistas e individualizadoras da identidade feminina que nos remete para uma mudança na atribuição do lugar social de homens e mulheres dentro e fora da família. Sobressai a valorização e enfatização da maternidade e do cuidado das crianças na identidade feminina; ao passo que aos homens se atribui uma maior valorização da atividade profissional. Esta constatação comprova a ambivalência e dicotomia de valores e atitudes entre uma fuga à convencional polarização entre papéis “masculinos” e “femininos” rígida e estereotipadamente definidos. / In Portugal, about two hundred organizations are committed to create and implement plans for men and women’s equality. These include public and private companies, local authorities, business associations, third sector organizations, development associations, universities, ministries and other governmental departments. The research exposed here is part of a broader diagnostic project taking placa in the City Hall, of Lousã which is promoting a Municipal Plan for Equality. In this context it was necessary to make an internal diagnosis to the organization from a perspective of gender, either in terms of gender inequalities in the composition and status of their workers or in order to know the workers representations around the phenomenon of women and men’s equality. To make it passible the organization provided statistical data which was analysed and subsequentaly a questionnaire was applied to the municipality staff. We concluded that there is the phenomenon of gender inequality in the structure of the organization namely occupational/professional segregation and vertical segregation, - men having the highest levels of seniority, which may justify in some way the existing wage gap. The study confirms a duality between the ideal of woman as a mother and housewife and the woman as an independent person, especially when the consequences suggested are related to their professional activity on their children and life family. The role of caring emerges as the obstacle to less traditionalist conceptions of female identity and individualization, which leads us to talk about a change of the social position of men and women within and outside the family. It points out the valuation and emphasizing of motherhood and care in female identity, whereas men are given a greater appreciation of the professional activity. This conclusion confirms the ambivalence and dichotomy of values and attitudes between escape from the conventional polarization between rigid and stereotypically defined roles of "male" and "female".

Objetivos: O presente estudo tem como objetivo geral caracterizar as redes sociais pessoais dos idosos com idade igual ou superior a 65 anos, analisando-as segundo o nível de satisfação com as relações interpessoais e a confiança nos outros. Metodologia: Este é um estudo descritivo e correlacional, privilegiando a análise bivariada. Os dados foram recolhidos através do Instrumento de Análise da Rede Social Pessoal, IARSP-Idosos (Guadalupe, 2009; Guadalupe & Vicente, 2012) e de uma escala de avaliação da Satisfação com as Relações Interpessoais, construída para o efeito, e de uma questão relacionada com a Confiança. Participantes: A amostra é constituída por 446 indivíduos, maioritariamente do sexo feminino (n=285; 63,9%), com idades compreendidas entre os 65 e os 98 anos; a maioria tem filhos (n = 389; 87,2%), e cerca de 80,0% (n = 357) vivem na sua casa, sendo a zona de residência essencialmente rural (61,2%; n = 273). A maioria tem escolaridade (65,9%; n = 294), sobretudo ao nível do quarto ano (n= 226; 50,7%). Resultados: Os resultados demonstram que os idosos do sexo feminino, com ≤ 75 anos, casado/a ou em união de fato, com filhos, que vivem acompanhados, com o 4ª ano de escolaridade e que não registam qualquer corte relacional, são os que mais confiam nos outros. Registam-se diferenças nas características funcionais da rede segundo esta variável, o que não acontece nas estruturais, com a exceção da proporção das relações com técnicos (p = 0,042) e nas relacionais-contextuais. A confiança nas pessoas com quem se relaciona correlaciona-se de forma positiva e estatisticamente significativa com a satisfação com os filhos, com os netos, com outros parentes, com os amigos e com os vizinhos (p<0,001). Conclusões: Numerosas variáveis sociodemográficas não aparentam estar relacionadas com a confiança nas pessoas com quem os idosos se relacionam, nas múltiplas dimensões consideradas. Em contrapartida, as variáveis que aparecem relacionadas com a confiança, são aquelas que, de forma mais ou menos direta, estão igualmente associadas ao domínio pessoal. É de salientar que no que respeita a esta variável se verificam diferenças nas características funcionais da rede o que não acontece nas estruturais e nas relacionais-contextuais. As relações familiares de filhos, netos e outros parentes são as que mais se associam à confiança e ao apoio social percebido pelos idosos, o qual é complementado por outras relações interpessoais, designadamente as que são estabelecidas com amigos e vizinhos. / Objetives: This study has the general objective to characterize the personal social networks of the elderly aged over 65 years, analyzing them according to the level of satisfaction with interpersonal relationships and trust in others. Methodology: This is a descriptive and correlational study, focusing on bivariate analysis. Data were collected through the Personal Social Networks Analysis Tool, IARSP-Elderly (Guadalupe, 2009; Vicente & Guadalupe, 2012) and a scale measuring satisfaction with interpersonal relations, purpose built, and a question related to the trust. Participants: The sample includes 446 individuals, mostly female (n = 285; 63,9%), aged between 65 and 98 years old; most have sons/daughters (n = 389; 87,2%), and about 80,0% (n = 357) are living in their home, mostly in rural areas (61,2%, n = 273). The majority have education (65,9%, n = 294), especially at the level of the fourth year (n = 226; 50,7%). Results: The results show that the elderly female, with <= 75, married, with children, living together, with the 4th grade, and did not record any relational cut, are the ones that rely in the others. We found differences in the functional characteristics of the network according to this variable, what does not happen on the structural variables, with the exception of the proportion of relations with workers in social services (p = 0,042), and on the relational-contextual. The confidence in the people he meets, correlates positively and statistically significant satisfaction with the children, with grandchildren, other relatives, friends and neighbors (p <0,001) Conclusions: Numerous sociodemographic variables do not appear to be related to trust in the interpersonal relationship, in the multiple dimensions considered. In contrast, the variables which appear related to trust are those which are associated with the personal domain. It is noteworthy that we have found differences in the functional characteristics of the network but not in the structural and the relational-contextual. Family relationships of children, grandchildren and other relatives are the most associated to the confidence and social support perceived by the elderly, which is complemented by other interpersonal relationships, including those with established friends and neighbors.

The principal purpose of this research was to investigate discriminant factors of survival and failure of micro and small businesses, and the impacts of these factors in the public politics for entrepreneurship in the State of Rio Grande do Norte. The data were ceded by SEBRAE/RN and the Commercial Committee of the Rio Grande do Norte State and it included the businesses that were registered in 2000, 2001 and 2002. According to the theoretical framework 3 groups of factors were defined Business Financial Structure, Entrepreneurial Preparation and Entrepreneurial Behavior , and the factors were studied in order to determine whether they are discriminant or not of the survival and business failure. A quantitative research was applied and advanced statistical techniques were used multivariate data analysis , beginning with the factorial analysis and after using the discriminant analysis. As a result, canonical discriminant functions were found and they partially explained the survival and business failure in terms of the factors and groups of factors. The analysis also permitted the evaluation of the public politics for entrepreneurship and it was verified, according to the view of the entrepreneurs, that these politics were weakly effective to avoid business failure. Some changes in the referred politics were suggested based on the most significant factors found.
