Políticas públicas de economia solidária: uma avaliação do PCPR II na microrregião de Angicos do Rio Grande do Norte

The Solidarity Economy is considered in this work as a development option. Talk about it is to think in the workforce as a producer of material wealth and, above all , subjective , therefore it is necessary to take into account that these relations coexist different types of practices that encompass emotions , lifestyles , etc. This research has as an object of study evaluating the effectiveness of public policy for Solidarity Economy, microrregion Angicos / RN, demonstrating how the Solidarity Economy has encouraged the development not only as a driving force for economic growth, but as the expansion capabilities and freedoms. The Solidarity Economy has several definitions, and despite having its origin in the cooperative movement, is a concept under construction. Focused on the discussion of public policy, is now understood as a proposal for employability, either as a generator of employment and income, reflecting its polymorphism. Theories and concepts developed by Amartya Sen is an important analytical tool for understanding the Solidarity Economy as a development strategy. When speaking of instrumental freedoms, Senniana theory contributes to reflection on how participants socioeconomic actions are becoming active agents of change i n their own freedoms. The analysis was based on the discussion of development beyond economic bias, using the lines of the vari ous local stakeholders with PCPR II, p hase 2, for microrregion Angicos / RN, comprising: public managers, technical advisors and beneficiaries of the program rural poverty alleviation. Besides the discussion of the economic organization of the RN and its spatial distribution, the survey brings the result that the Solidarity Economy in microrregion Angicos / RN contributed to the dev elopment as freedom, proving the effectiveness of public policy by allowing an improvement in the quality of life, enabling efetivations, even without major proportions.

Caracterização da caprinocultura nas microrregiões da chapada do Apodi e de Angicos do Estado do Rio Grande do Norte

The objectives of this study were to characterize the goat production systems and to identify the factors limiting the production chain and develop solutions to improve the goat industry in the Rio Grande do Norte State, Brazil. One hundred and sixty two questionnaires were applied to goat farmers looking for productive, economic and social information about the utilized systems in the micro regions of Chapada do Apodi and Angicos. The majority producers interviewed were male, aging from 31 to 50 years old, attended elementary school, associated to farm organizations and living with his family on farm. Their main concerns are feeding the heard and animal theft. Their average farmlands areas range from 11 to 50 hectares. Goat meat is the main production in Chapada do Apodi whereas milk is produced by farmers in Angicos micro region. The majority of goat production works with an extensive system, with low technological inputs. It was detected that the meat and milk production as the marketing of goat products is not well conducted. Other point to be improved is to increase the meat and dairy goat products to be available for consumers. Goat systems for meat and milk production has great to potential for this micro regions, although public policies for an organized supply chain is needed

Caracterização dos sistemas de produção de leite bovino na microrregião Seridó do estado do Rio Grande do Norte

The objective was to contribute to a reading of the characteristics and diversity of production systems from bovine milk in the microregion Seridó of Rio Grande do Norte, discuss the social, economic, environmental and husbandry-related primary activity of milk production. We randomly selected 28 agricultural establishments that performed the activity of dairy bovine culture with subsequent applicat ion of a structured questionnaire during September and October 2011. Data were analyzed with application of measures of descriptive analysis and determination of the index rural development (IRD). The results showed that 53.57% of the interviewees were owners of the land, the median area of the properties amounted to 135 hectares, the median number of animals in the herd was 51 head, with minimum 11 and maximum of 350 heads establishments in the sample, 85.72% of establishments had maximum 23 cows in lactation, 100% performed manual milking with suckling calves, average productivity of 3.91 liters / cow / day, 92.86% of the interviewees did not produce silage and / or hay, 64.29% had no access to technical assistance, the average age of interviewees was 51 ± 10.85 years, 78.57% had only elementary education. The average of the IRD computed in the test sample amounted to 0.43 ± 0.11 on a scale 0-1. The sites were grouped into 04 classes, based on your IRD. The average IRD in each dimension was 0.43, 0.55 and 0.34, respectively for economic / husbandry, social and environmental. The determination of the rate of rural development - IDR found for the sample could add establishments hierarchically. It is necessary that the inclusion of best practices in herd management, bookkeeping zootechnical, technical assistance and reorganization practices in land and environmental preservation

Análise da frequência alélica de 15 LOCI STR na população do Rio Grande do Norte

Human population have a significant number of polymorphic loci, whose use and applications range from construction of linkage maps, to study the evolution of populations, through the determination of paternity, forensic medicine and migration. Currently, STRs (Short Tanden Repeats) markers are considered the major markers for human identification, mainly due to its abundance and high variability because of the fact that they are easily amplifiable by PCR (Polymerase Chain Reaction), work with low amounts of DNA and be capable of automation processes involving fluorescence detection. The creation of regional databases containing allele frequencies of population provide subsidies to increase the reliability of the results of determining the genetic link. This paper aims to obtain a database of allele frequencies of 15 polymorphic molecular loci (D8S1179, D21S11, D7S820, CSF1PO, D19S433, vWA, TPOX, D18S51, D3S1358, TH01, D13S317, D16S539, D2S1338, D5S818 e FGA) in a population classifies as born in the State of Rio Grande do Norte, Brazil, totaling 1100 unrelated individuals. To evaluate the frequency, DNA samples were submitted to PCR amplification, followed by capilarry electrophoresis genetic sequencer. The frequencies identified in this study were compared with brazilian population in general and other states in Brazil. Except for the loci D21S11, D19S433 and D2D1338, the genotypes found were in Hardy-Weinberg equilibrium and no significant differences among the frequencies were found in the populations studied. The most informative loci was D2S1338 and D18S51, and the less informative is the locus TPOX

Gestão ambiental em cadeias produtivas agroindustriais: um estudo em um aglomerado produtivo da caprinovinocultura no Estado do Rio Grande do Norte

This thesis aims to investigate the perception and behavior of goat and sheep rural producers from Central Cabugi Region of Rio Grande do Norte state, in terms of the sector competitiveness, the cooperation mechanisms, information and environmental practices integration in the supply chain, including their customers, and also among the local producers and other institutions that support this agribusiness cluster. The research problem is related to the environmental impacts from goat and sheep breeding. This problem can also be intensified by the organization of producers in a cluster. Then, it is important to examine how the environmental issues are considered by the rural producers and their perception of their suppliers, customers and the institutions that support this activity. The methodology used in this work involved literature review of the topics of supply chain management, green supply chain, clusters development and sustainable livestock. An exploratory survey research was also conducted by personal interviews using questionnaires. Three statistic techniques were used to compile the gathered data: descriptive statistics, cluster analysis, and Chi-square tests. Two clusters were found in this study, however, the entire sample believes the sector of goat and sheep breeding is a medium competitive activity. On the other hand, for the variables of the importance of environmental practices for competitiveness , perception of environmental impacts and environmental benefits from farm vegetation management , the research found 2 distinct groups of individuals when those variables were analyzed together the green supply chain management group of variables in the cluster analysis. Beyond competitiveness perception, no degree of difference was found for the use of insecticides too. The chi-square tests present that producers having at least elementary education, lands bigger 100 hectares and located in the cities of Angicos or Lajes tend to have a higher perception to supply chain management and environmental awareness issues than those with no or incomplete first-level education, producing in lands smaller than 100 hectares and located in the cities of Afonso Bezerra or Pedro Avelino. The chi-square tests also show the amount of milk produced, family s income and associational condition are not related with the variables used in the clusters composition. In this context, this work contributes to planning clusters development strategies and enhancing the production chain sustainability. This Master of Science Thesis can also help to introduce the environmental variable in the project, assessment and monitoring of development policies as well

Alterações ambientais em Parelhas, Rio Grande do Norte: metais pesados em sedimentos de drenagens e percepção de comunidades rurais em relação a mudanças na paisagem

The conservation of natural resources is essential and constitutes the main subject of many researches, which characterize important aspects concerning the environmental alterations in the ground, water, landscape and socioeconomic information. This study aimed to investigate the anthropogenic input of heavy metals in the environment, in the area of the Parelhas dump site and in part of the Seridó River and to determine the concentration of heavy metals in the sediments. This can result in risk to the environment and human health. In addition, we sought to establish the socioeconomic profile of rural communities adjacent to Seridó River and to comprehend the perception of these dwellers about the changes in the places they live. The area of this study is located in the city of Parelhas/RN, in the centralsouthern part of the State, in the micro-region of the Oriental Seridó. This area comprehends the place where the dump site is located, next to RN 086, the Caldeirão dam, the Quintos river called by local citizens Caldeirão creek and part of Seridó river, perpetuated by the Boqueirão dam, which crosses the city and it includes the rural communities of Almas, Domingas, Sussuarana II and Colonos. Regarding the study with bottom sediments, the samples were collected and taken to the laboratory of geochemistry, where they were dried, sieved, weighted and submitted to weak acid attack. The analysis of heavy metals was held by Atomic Absorption Spectrophotometer - Flame AAS. We applied 23 closed questionnaires constituted by 38 questions to collect informations in the rural communities, oriented to establish the socioeconomic profile and the environmental perception of the participants. The participants were distributed in the communities of Almas (1), Domingas (2), Sussuarana II (10) and Colonos (10). Most of them presented similar socioeconomic profiles. They are from 45 to 60 years old and live in these localities for 20 to 30 years or more. The families are composed by 3 or 4 people; the agriculture is the main activity, livestock is the secondary and 48% of them earn the minimal wage. Regarding the environmental perception, the participants can realize some changes in vegetation, soil, water and landscape. People living longer in the community, and with more years of experience on the local reality can perceive the depletion of the soil, pastures and changes in the landscape. These changes portray how the place was previously and what it represents today. The perception of these changes, besides the environmental ones, includes others concerning the increasing number of dwellers in the last years, as well as the number of houses. The changes happened through activities developed by the dwellers over the years, including agricultural practices, livestock, grass planting and even the cultivation of cotton. The study provided the acquisition of new data about the environmental reality of this region. It can subsidize the definition of public policies that can be implemented from the perspective of conservation of water resources and of the coexistence and survival of man in the semi-arid

Sibilância em crianças e adolescentes vizinhos a uma indústria petroquímica no Rio Grande do Norte, Brasil

OBJETIVO: Verificar a associação entre relato de sibilância em crianças e adolescentes e o local de residência em relação à dispersão dos poluentes atmosféricos emitidos pelo Pólo Petroquímico (PPQ) de Guamaré (RN). MÉTODOS: Estudo transversal de relato de sibilância em crianças e adolescentes de 0 a 14 anos de idade, residentes no entorno do PPQ de Guamaré, em 2006. Foi utilizado o questionário padronizado do International Study of Asthma and Allergies in Childhood, acrescido de questões relativas ao tabagismo, renda, moradia e escolaridade. Concentrações diárias de PM10, PM2,5, carbono grafítico, SO2, NO2, O3, benzeno, tolueno e xilenos foram medidas em uma estação de monitoramento fixa. As comunidades residentes na área de influência das emissões do PPQ foram classificadas, segundo a direção preferencial dos ventos, em expostas e de referência. RESULTADOS: Participaram do estudo 209 crianças e adolescentes. As concentrações médias diárias dos poluentes monitorados mantiveram-se abaixo dos limites estabelecidos nos padrões de qualidade do ar. A prevalência de sibilos nos últimos 12 meses foi de 27,3%. Associações estatisticamente significantes com sibilos nos últimos 12 meses foram verificadas mesmo após ajustamentos para comunidades expostas [razão de chances (odds ratio, ORajust) = 2,01; intervalo de confiança de 95% (IC95%) 1,01-4,01], gênero masculino (ORajust = 2,50; IC95% 1,21-5,18) e idade de 0 a 6 anos (ORajust = 5,00; IC95% 2,41-10,39). CONCLUSÃO: Mesmo em baixas concentrações de poluentes atmosféricos, a ocorrência de sintomas respiratórios em crianças e adolescentes nas comunidades no entorno de um PPQ esteve associada a residência na direção preferencial dos ventos, mostrando-se mais vulnerável o grupo de pré-escolares do gênero masculino.

Prevalence of anti-Toxoplasma gondii and anti-Neospora caninum antibodies in sheep from Mossoro, Rio Grande do Norte, Brazil

Toxoplasma gondii is an obligate intracellular parasite with a variety of hosts, responsible for reproductive problems and economic losses in sheep flocks. Neospora caninum was recently identified and its clinical presentation in sheep is similar to that of toxoplasmosis, which can cause repeated abortions, though less frequently in this species. In order to confirm the prevalence of these agents in the city of Mossoro, Rio Grande do Norte, Brazil, 409 serum samples from adult sheep (364 females and 45 males) were tested by the indirect immunofluorescence antibody test, using cut-off point at a dilution of 1:64 and 1:50 for T. gondii and N. caninum, respectively. From the 35 properties examined, 23 (65.7%)had at least one seropositive animal for T gondii and six (17.1%) for N. caninum. The prevalence of seropositive animals for T. gondii was 20.7% and for N. caninum 1.8%. There was no association between the presence of the agent`s antibody and gender, reports of reproductive problems and presence of dogs and/or cats in the properties. T. gondii is well distributed and N. caninum has low prevalence in sheep and in the properties of the studied region. (C) 2008 Elsevier B.V. All rights reserved.

Prevalence and risk factors for anti-Toxoplasma gondii antibodies in goats of the Serido Oriental microregion, Rio Grande do Norte state, Northeast region of Brazil

The prevalence and risk factors for anti-Toxoplasma gondii antibodies were investigated in goats of the Serido Oriental microregion, Rio Grande do Norte state, Northeast region of Brazil. Three hundred and sixty-six blood samples from goats collected by jugular venopuncture were used. For the serologic diagnosis of Toxoplasma gondii infection, the indirect fluorescent-anti body test (IFAT) with cut-off value 1:64 was carried out. The prevalence of anti-T. gondii antibodies was 30.6% [95% CI = 25.9-35.6%] with titers ranging from 1:64 to 1: 16,384. The multivariate logistic regression analysis showed that the risk factors associated to anti-T. gondii antibodies were presence of cats in the herd, extensive/semi-intensive management systems and lack of mineral supplementation.

Caracterização física e química de híbridos de tomate em diferentes estádios de maturação produzidos em Baraúna, Rio Grande do Norte

O tomate é uma das olerícolas mais consumidas no mundo. Na região nordeste do Brasil, é comum a comercialização de cultivares industriais para consumo in natura. Este trabalho teve como objetivo avaliar algumas características de qualidade de dois híbridos de tomate industrial ('Mariana' e 'SM -16'), em quatro estádios de maturação (verde - 1; salada - 2; colorido - 3; vermelho - 4). Após a colheita, os frutos foram transportados para o Laboratório de Tecnologia de Alimentos da Universidade Federal Rural do Semi-Árido, onde foram selecionados de acordo com a uniformidade de maturação e avaliados de acordo com diâmetro longitudinal e transversal, massa de matéria fresca, firmeza da polpa, sólidos solúveis, pH, vitamina C e açúcares totais. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 2 x 4 (dois cultivares e quatro estádios de maturação). Os dados foram submetidos análise de variância e as médias comparadas pelo teste de Tukey, a 5%. Observaram-se diferenças na qualidade física e química dos frutos, entre híbridos e entre estádios de maturação. A massa de matéria fresca dos frutos, o diâmetro transversal e a firmeza da polpa dos tomates pertencentes ao híbrido 'SM-16' foram superiores aos do híbrido 'Mariana'. Houve aumento da massa de matéria fresca até o estádio de maturação 3 e decréscimo da firmeza e do pH da polpa, com o amadurecimento dos frutos. O teor de vitamina C dos frutos aumentou do estádio 1 para o 2, e o híbrido 'Mariana' apresentou maior teor de vitamina C.

Produção e qualidade de melão Cantaloupe em cultivo protegido temporariamente com agrotêxtil em Mossoró, Rio Grande do Norte

Desde o ano de 2001, na região do agropolo de Mossoró/Assu-RN, o agrotêxtil é utilizado como proteção de plantas contra pragas da cultura do meloeiro. Este experimento teve como objetivo avaliar a produção e a qualidade de dois híbridos de melão Cantaloupe, em cultivo protegido, temporariamente, com agrotêxtil. O trabalho foi realizado na Horta da Universidade Federal Rural do Semi-Árido (UFERSA), em Mossoró-RN, de julho a outubro de 2010. O delineamento experimental foi de blocos casualizados completos, com quatro repetições, dispostos no esquema de parcelas subdivididas no espaço. As parcelas foram representadas pelo número de dias após o transplante das mudas (DAT), em que as plantas permaneceram sob proteção de agrotêxtil (0; 18; 21; 24; 27 e 30 DAT) e, as subparcelas, por dois híbridos F1 de melão Cantaloupe: 'Acclaim' e 'Caribbean Gold RZ'. Foram avaliadas características de produção e de qualidade. Os tratamentos com proteção temporária com agrotêxtil não afetaram a produtividade total dos dois híbridos; todavia, a firmeza de polpa apresentou aumento crescente, enquanto a acidez total titulável, os açúcares solúveis totais, os sólidos solúveis e o pH apresentaram redução com o aumento do tempo de permanência do agrotêxtil sobre as plantas. O 'Caribbean Gold RZ', em comparação com o 'Acclaim', apresentou maior produtividade comercial para exportação, maior massa média de frutos, mais firmeza de polpa, maior acidez total titulável, maior teor de sólidos solúveis e menor pH.

A política afirmativa "Argumento de Inclusão" como forma de acesso à universidade pública: o caso da Universidade Federal do Rio Grande do Norte

Antes da aprovação da Lei no 12.711/2012, que institui constitucionalmente a reserva de vagas nas universidades federais, modelos de inclusão foram amplamente discutidos e aplicados em diferentes instituições públicas de ensino superior. A pesquisa aqui exposta analisa e discute o Argumento de Inclusão (AI) - política de ação afirmativa que fornece pontuação adicional aos alunos provenientes de escolas públicas - existente na Universidade Federal do Rio Grande do Norte (UFRN) entre os anos de 2006-12. A partir de uma ampla base de dados, foi usada a técnica dos Mínimos Quadrados Ordinários (MQO) e uma Regressão Quantílica considerando como controles as variáveis das características pessoais, socioeconômicas e escolares dos candidatos ao Vestibular 2010 da UFRN. Os resultados mostram a relevância do sistema de pontuação adicional como incentivo para o acesso inclusivo ao ensino superior, e apontam novas evidências acerca de variáveis que afetam positiva e negativamente este acesso.
