Estudo sobre a mortalidade e sobrevivência de micro e pequenas empresas natalenses e seus impactos nas políticas públicas pró-empreendedorismo

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.

Caminhos de sobrevivência institucional: a gestão do núcleo de oficinas e artes profissionalizantes laís aderne

The object of this study is the organizational management, particularly the relational processenvironment organization focused on the survival of the space Department of the Arts and Crafts Mestre Raimundo Cardoso linked to the structural arrangement of the Liceu do Paracuri.. Aimed to understand the ways of organizational survival, from the actors' perception of the Center for Arts Career Workshops and Lais Aderne, with investments that discuss the theoretical models of management, institutional theory, cultural organization and institutionalization of public education requirement of the municipal light LDB. (1996) used a qualitative approach with a view to RICHARDSON (1985). The data generated were analyzed based on the technique of content analysis, the thematic type [categorical] Bardin (1977). The results indicate that the institutionalization of the arrangement of the Liceu do Paracuri emerges meet the legal requirement of the autonomy of municipal educational administration under the aegis of sustainable development, quality of life and basic education from the municipal Hélio Gueiros (1993-1996 ). More specifically the Center for Arts and Crafts Laís Aderne, the unit of analysis, the subjects said that this space is designed as a link between the demands of school and community searching through interdisciplinary activities educate and train manpower mainly potter. They did mention the existence of institutional factors (history, culture, habits, values) represent a strong socio-cultural element to the actors belonging to the core that guides behavior and actions of these individuals, fueled by a sense of hope, inclusion of future artisans in culture ceramist. It made a shared management, the existence of a unique work through cultural revival. However, over the course of time, the core is faced with dilemmas of managing transitions mainly regarding governmental, technological beyond endurance by the craftsmen for the optimization of their work. The conclusion - that the paths chosen for the organizational survival of the core meaning and guiding their actions in the systematization of conduct, representations, memories and traditions through habits and choices of consensus, the viewpoint of the actors

Vicilina de sementes da leguminosa selvagem Anadenanthera macrocarpa (AmV): purificação, caracterização, efeito deletério e mecanismo de ação para bruquídeo callosobruchus maculatus

Grains and legume seeds are foods that form the basis of the diets of many cultures around the world, winch contritbute to the daily nutrient requirements of humans. Vicilins (7S globulin) are storage proteins found in legume seeds, and may have an additional function constitutive defense of the embryo against pests and pathogens. In this work the vicilin from Anadenanthera macrocarpa - AmV (red-angico), was purified and partially characterized, its effect on development and larval survival and adult emergence of Callosobruchus maculatus was evaluated by determination of LD50, WD50 and ED50 in system bioassay. Purification of vicilin was initiated by the chitin affinity chromatography and then gel filtration (Superdex 75 Tricorn 10x300 mm) FPLC system followed by reverse phase chromatography (C8 phenomenex) on HPLC system. Bioassays WD50 and LD50 for larvae were 0.32% and 0.33% (w:w) respectively, since the ED50 for adults was 0.096%. The probable mechanism of action was evaluated by testing digestibility of AmV in vitro, and observed for the involvement of two fragments vicilins immunoreactive against polyclonal Anti-vicilin from Erythrina velutina (Anti-EvV) about of 22 and 13 kDa chitin binding. The AmV in its native form has been recognized by the anti-EvV, indicating that there is a conserved region in the vicilin and is probably corresponding to the chitin binding domains. These results point to a new vicilin chitin binding that can subsequently be used as a possible biopesticide protein source, in order to control insect pest C. maculatus and confirm literature findings that demonstrate vicilin in the presence of different kinds of ligands to conserved regions chitin not yet characterized

Efeito de um extrato de Ganoderma lucidum (Reishi) na marcação de constituintes sanguíneos com tecnécio-99M e na sobrevivência de Escherichia coli

Clinical evaluations have been made possible with radiobiocomplexes marked with tecnecium-99m (99mTc). Natural or synthetic drugs are able to interfere in the marking of blood structures with 99m Tc. Also, the toxicity of several natural products has been described. The aim of this study was evaluating the effect of an extract of Ganoderma lucidum (Reishi) in the marking of blood constituents with 98m Tc and in the survival of Escherichia coli. Blood samples from Wistar rats were treated with reishi extract. Radiomarking procedure was performed. Samples of plasma (P), blood cells (CS), and insoluble (FI) and soluble (FS) fractions of P and CS were separated and the radioactivity was counted to determine radioactivity percentages (%ATI). Escherichia coli AB1157 cultures were treated with stannous chloride in the presence and absence of the reishi extract. Blood samples and bacterial cultures treated with NaCl 0.9% were used as controls. Data indicated that the reishi extract has significantly altered (p<0,05) the %ATI of P, CS, FI-P, FS-P, FI-CS e FS-CS, as well as it has increased survival of bacterial cultures treated with stannous chloride. Our results suggest that the Reishi extract would be able to present a redox/ chelant action by altering blood constituent marking with 99mTc and by protecting bacterial cultures against stannous chloride-induced oxydating lesions. The study had a multidisciplinary character, with the participation of the following areas of knowledge: Biophysics, Radiobiology, Botanics, Phytotherapy, and Hematology

Barreiras de sobrevivência: angústias e dilemas de jovens infratores pós-institucionalização

This study critically examines the effects of public policies, implemented by Fundação Estadual da Criança e do Adolescente (FUNDAC/RN), along with adolescents of both sexes, perpetrators of illegal acts in compliance by court order, by socio-educative measures , identifying the contradictions that permeate the understanding and treatment of issue. The aim is to investigate the chances that youths have by living in Centro Educacional Pitimbu and Centro Educacional Padre. João Maria (CEDUC), to become subjects in the exercise of their citizenship. The methodology adopted is the verbal history of life (MEIHY, 2005) of youths that had life experiences in these institutions from 2002 to 2005, allowing researchers to access directly to investigated individuals, through the place where they currently reside, and enabling the reconstitution of their life story, from semi-structured interviews. The young people s statements interviewed were grouped and analyzed from the following categories of analysis: the egress and family, the school and egress, the community and egress, the egress and work, the egress and CEDUC, the egress and experience infringement. The results indicate that, despite the advances in Brazilian legislation for the sector, the actions promoted by these institutions generally would have produced innocuous and stigmatized consequences. Moreover, they show in essence that they carry on their inner contradictions which fundamentally correspond to the interests of the dominant system and a society which uses mechanisms of social policy, in addition to favoring the control and repression. And thus, while such actions remain unable to produce important changes in the conditions of existence of young people who meet by social deprivation of liberty, it is possible to say that the chances are minimal so that they become autonomous subjects in a society that, preferring their punishment, denies them, stubbornly, access to their basic rights. In theory, the researcher dialogues with authors as Foucault, Goffman, Bourdieu, Offe, Bauman, Boaventura Santos, Takeuti, Germano, Ariès, Wacquant, among others

Sobrevivência e tamanho populacional do Tiê-preto Tachyphonus Rufus (aves: thraupidae) em fragmento de restinga no extremo Norte da Mata Atlântica

For a long time, we believed in the pattern that tropical and south hemisphere species have high survival. Nowadays results began to contradict this pattern, indicating the need for further studies. Despite the advanced state of the study of bird population parameters, little is known about their variation throughout the year and the factors affecting them. Reproduction, for example, is one factor that may alter adult survival rates, because during this process the breeding pair allocates resources to maintain itself to maintain offspring, making itself more susceptible to diseases and predation. The aim of this study was to estimate survival and population size of a Central and South America passerine, Tachyphonus rufus (Boddaert, 1783), testing hypotheses about the factors that define these parameters. We performed data collection between Nov/2010 and ago/2012 in 12 ha plot, in a fragment of Atlantic Forest in northeastern Brazil. We used capture-mark-recapture methods to generate estimates using Closed Design Robust model in the program MARK. We generated Multi-state models to test some assumptions inherent to Closed Robust Design. The influence of co-variables (time, rain and reproductive cycle) and the effect of transient individuals were measured. Capture, recapture and apparent survival parameters were defined by reproductive cycle, while temporary dispersal was influence by rain. The estimates showed a higher apparent survival during the non-breeding period (92% ± 1%) than during breeding (40% ± 9%), revealing a cost of reproduction and suggesting a trade-off between surviving and reproducing. The low annual survival observed (34%) did not corroborate the pattern of high rates expected for a tropical bird. The largest population size was estimated to be 56 individuals in Nov/11, explained by high recruitment of juveniles, while the lowest observed in May/12: 10 individuals, probably as a result of massive influx of competitor species. Results from this study add to the growing literature on life history of Neotropical species. We encourage studies like this especially in Brazil, where there are few information, and suggest that covariates related to habitat quality and environmental changes should be tested, so that we can generate increasingly reliable models

Diferentes granulometrias de rações sobre o ganho de peso, crescimento, sobrevivência e reversão sexual para tilápias-do-Nilo (Oreochromis niloticus)

The aim of this work was to evaluate the effects of three different diameters of crumble diets (0.25, 0.35 and 0.50 on weight gain, growing, survival and sexual proportion to Nile tilapia (Oreochromis niloticus) larvae with 30, 60 and 90 days of age. In the first 30 days of age larvae were submitted to sex reversion with diets containing the hormone 17[alpha]-methyltestosterone in a dosage of 60mg/kg of ration, respecting the different diameters and after this period, larvae were measured, weighed and counted for calculation of survival taxes. For the biometrical parameters as weight total length a completely randomized design was used in subdivided installments with three treatments and repetitions, considering installments the three diameters of diet and the sub installments, the three ages. In the end of this study, fish fed with diets of grain diameters 0.35 and 0.25 mm obtained the best results for weight gain (14.42g and 13.36 g) and total length (83.13 mm and 82.72 mm), although these results were not statistically significant, and with grain diameters 0.50 and 0.35 mm resulted in 96,66 % and 93,33% of males, respectively, after histological an, of gonads, without statistics differences between the treatments.

O Evangelho segundo a Pastoral da Criança :por uma pedagogia da sobrevivência

This work aims to analyze social and educational actions at Pastoral da Criança, using education as a survival tool. This was done at Parque dos Coqueiros, a neighborhood in Natal, Rio Grande do Norte. The methodology for data collection was composed of comprehensive interview (Jean Kaufmann), participant observation (Robert Bogdan) and documental analysis (Le Goff); all os which bring reflections related to concepts such as strategies, tatics and know how (Michel de Certeau), configuration (Nobert Elias), and control technology (Michel de Foucault), care ethics (Leonardo Boff) and etno-theories (Natália Ramos). Pastoral da Criança is a social action organism that belongs to the National Conference of Bishops of Brazil, originated at Florestópolis, Londrina (Paraná), in the year of 1983. These actions have been an expression of a new logic of actions of the Catholic Church. It values the participation of laymen in the activities of the Pastoral. Thus, the parish is seen as a nucleus that irradiates the Church s Social Doctrine. At Rio Grande do Norte this institution has guided poverty stricken families on issues related to children s health as well as working with laymen for volunteer work. This is considered devotion, that is firmed by an individual and group mystique. The social and educational actions are done in three axes: 1) Monthly home visits, where there is mother-child support; 2) Life Celebration Day, where they weigh children and promote nutritional surveillance; 3) Meeting for Evaluation and Reflection, that aims to articulate community leaders to think about problems attached to the social actions they realize. This action tripod , as it is called by the Pastoral Agents are the types of actions that fundament survival education for poor children ranging from 0 to 6 years old. The families learn to deal with prevention, the essential, the alternative and probabilities of survival tactics due to exclusion matters or even social extermination. The Pastoral da Criança aims to recover childhood emotions in poverty stricken areas. It also has influence in the diminishing of malnutrition and mother and child mortality. This education for survival is the base on the art of teaching and learning of poverty stricken children. It is a social educational action, non assistencialist, but considered a shy action in order to promote mobilization of the communities that are accompanied for the emancipation and change of social conditions

A gestão do conhecimento e a inovação tecnológica como fatores de sobrevivência e de competitividade na sociedade do conhecimento: uma análise exploratória das MPEs do Rio Grande do Norte

The study examines the process of Knowledge Management and Technological Innovation in Small and Micro Enterprises (SME) in Rio Grande do Norte, Brazil, and proposes actions that can contribute to regional development and competitiveness of SME. Presents as technological innovation can help to make the SME entrepreneurial activities with innovative and competitive. Defines the phases and activities of the construction of knowledge in small organizations. Examines the process of Innovation, Research and Development (R & D) in SME. Identifies the use of knowledge management and technological innovation in management practices and social interaction to influence the competitiveness of SME. Covers the communities of practice as a diffuser of knowledge and learning. To obtain the data were used questionnaires with closed questions with multiple choice, direct observations and interviews with companies. The questionnaires and interviews covered the topics of Innovation, Knowledge Management and Competitive Intelligence on SME. The sample consisted of a total of 13 Small and Micro Enterprises Award winning MPE Brazil Competitiveness, sponsored by SEBRAE in the State of Rio Grande do Norte. The assessment questionnaires dealing with the Knowledge Management (KM Diagnostics - Model Bukowitz and Williams, 2002) and the process of Technological Innovation (Adaptation of ANPEI - National Association for Research, Development and Engineering of Innovative Companies). With the analysis, we concluded that the SME perceive knowledge management, but not formalized management practices so as to facilitate the dissemination of information. Soon, these companies need additional supports to direct them to the innovative activities that generate added value and competitiveness in the market

Efeito do probiótico Bacillus subtilis no crescimento, sobrevivência e fisiologia de rãs-touro (Rana catesbeiana)

The probiotics are live microorganisms, in latency state, that benefices the development of the animals. The objective of this work was to evaluate the effect of the Bacillus subtilis in different doses about the growing, survival and immunological and hematological analyses in the Bullfrog (Rana catesbeiana) froglets. The test was developed in Experimental Frog farm of Agriculture Department, Pindamonhangaba, SP. Three doses of probiotics were tested (T1 - 2.5 g/Kg, T2 - 5 g/Kg and T3 - 10 g/Kg of food). The test was carried out with three simultaneous replicates, plus control group. The products were added to froglet's diet and mixed to the meal. The animals were previously feed with this diet for a period of 14 days and accompanied for about 42 days after metamorphose. Biometrics were performed every 7 days. It was evaluated the final weight, the survival, phagocytic capacity, phagocytic index and hematological analyses as hematocrit, hemoglobin level, erythrocyte number, absolute indices hematimetrycs (MCV and MCHC), differential counting of leucocytes and total counting of leucocytes and trombocytes. The results had shown that the doses of the probiotics had produced none effect on the final weight and survival. The immunological analyses had shown that the probiotics have presented immunostimulator effect, but haven't influenced the hematological parameters of the animals.

Manejo hídrico em viveiro e uso de hidrogel na sobrevivência pós-plantio de Eucalyptus urograndis em dois solos diferentes

O trabalho teve como objetivo avaliar a sobrevivência do clone H13 de Eucalyptus urograndis sob dois manejos hídricos de viveiro, plantados em dois solos, com e sem a adição de polímero hidroabsorvente (hidrogel). O plantio foi realizado em vasos mantidos em estufa, com dois tipos de solo: um arenoso e outro argiloso. Cada vaso recebeu 2,5 L de solo, um litro de água e o hidrogel na proporção de 0,4 g vaso-1 (120 mL de gel). O delineamento experimental adotado foi o inteiramente casualizado, com três repetições. Os sintomas de estresse, nos vários níveis avaliados, sempre se manifestaram primeiro nas plantas no solo argiloso, de modo mais acentuado naquelas que foram mantidas sem estresse de água na fase de viveiro. Isso garantiu que as plantas sobrevivessem por um período menor sem água, variando de 14 a 20 dias (com e sem hidrogel, respectivamente), enquanto, no solo arenoso, a sobrevivência foi maior, de 29 a 34 dias (com e sem hidrogel, respectivamente). Apesar da não significância estatística, os resultados com o hidrogel possibilitam, em ambos os solos, maior flexibilidade operacional na intervenção com novas irrigações.
