O mercado de trabalho no Mercosul

Inicialmente abordamos as tentativas de integração latino-americana, identificando as duas épocas distintas da problemática em questão. Faz-se menção a vários autores, abrangendo a segunda metade do século XIX e as primeiras décadas do séculos XX, que também defenderam as idéias de união latino-americana. A importância da criação da Comunidade Econômica Européia, a ALALC, A ALADI e o MERCOSUL como impulsionadores da integração. A institucionalização, os mecanismos para implementação e os processos de negociação do MERCOSUL. Em seguida tratamos da globalização e do mercado de trabalhos; a produção internacionalizada marcante no século XX; as novas tecnologias, a cidadania ativa, a reação sindical em novas bases. No terceiro capítulo abordamos a questão trabalhista no MERCOSUL, enfatizando a necessidade de implantação de princípios assegurando benefícios, tendo em vista a tendência comercialista do MERCOSUL. Concluindo, retomamos a relação entre as Centrais e os governos, destacando, ainda, as organizações internacionais como importantes atores no processo de integração. Constatamos o quanto o MERCOSUL está estimulando discussões sobre as possibilidades de alianças entre os atores sociais.

Retenção de talentos por meio de reconhecimento e recompença

Esta dissertação objetivou verificar até que ponto os mecanismos de reconhecimento e recompensa são motivadores à retenção de talentos. Considerou que há pessoas que fazem o diferencial das organizações por deterem competências de difícil aquisição e de importância estratégica. No entanto, essas competências serão perdidas se não estiverem vinculadas aos objetivos das organizações e se não forem estabelecidas relações entre o desempenho e as práticas de reconhecimento e recompensa adotadas. Como base, buscou-se em disciplinas como a Psicologia, a Sociologia e as ciências da Administração, fundamentos teóricos que viessem auxiliar na resposta ao problema formulado. Este referencial mostrou a importância da retenção do talento, assim como descreveu e analisou algumas das muitas variáveis que poderiam impactar a construção de vínculos psicológicos entre o talento e a organização, ressaltando os principais componentes do processo motivacional na retenção. Também, permitiu identificar e analisar os principais mecanismos de reconhecimento e recompensa que poderiam ser adotados na valorização e retenção de talentos e relacionou-os com três correntes da motivação, criando um modelo conceitual de avaliação da retenção. Os resultados deste estudo serviram de orientadores à pesquisa de campo, que buscou conhecer quais os mecanismos de reconhecimento e recompensa que mais motivam os talentos a permanecerem em uma organização, bem como, avaliou se os mecanismos ditos motivadores, quando efetivamente praticados, causariam impacto na motivação do talento no decorrer do tempo. iii A análise dos resultados da pesquisa validou o modelo conceitual, concluindo que dos trinta e um mecanismos estudados apenas oito têm força de retenção, estando sete deles associados a formas de reconhecimento, aprovação e crescimento profissional. Os resultados não rejeitam as hipóteses e concluem que reconhecer e recompensar talentos vai muito além de abonos e prêmios pecuniários e materiais. Embora estímulos externos contribuam, a motivação em permanecer em uma organização é intrínseca ao talento e está associada ao seu espaço de vida, no momento em que ele se percebe integrado ao grupo, e respeitado, tendo seu esforço reconhecido e recompensado de forma justa.

Democracia Possível: espaços institucionais, participação social e cultura política

The present study aims at making a theoretically reflection about the reconstruction process of democracy that can be observed in the country since the opening political process, which took place with the Geisel´s government in 1974, passing through the first civil president, in 1985, the Constitution process, in 1986, and finally the Constitution promulgation in 1988. It interests to this study analyses the premise that the 1988 Constitution inaugurates the moment in which democracy starts to be reconstructed in the country, and that this reconstruction is made in such a brand new way, once it included the possibility of participation of the civil society in the deliberation of the public politics, what became possible with the creation of new spaces of a gestion shared by the three executive powers: federal; states; municipalities, and with the civil society, in the councils created in those spheres. In this way, this work wishes to focus the opening process to the civil society participation, wich became possible with the creation of the city councils of public politics. It´s about investigating the form in wich the relations set up in these hibrid spaces could be considered democratic, inclusive and promoters of effective participation, checking up tendencies, giving emphasis to regularities and some specifities encountered in the forms of participation, which have been observed in those councils. In order to comprehend the democratic process in construction in the country, the analysis of the relations established by the civil society and the local executive power in the obligatory municipal councils is taken as object of study, passing by the tensions wich evolves institutions and political practices, permeated by the local political culture. It starts from a briefly review of works already made on the subject

Cidades e turismo sustentável:a cooperação interinstitucional no Conselho de Desenvolvimento do Turismo do Pólo Costa das Dunas/RN

It treats tourism as part of the places urban development dynamics and the touristic urbanization process as a strategy of cities international competitiveness strengthen, detaching institucional agents role as promoters of this process. It aims to understand how happens the interinstitucional cooperation existing between the agents (Estate, private initiative and third sector) that composes the Development Council of Pólo Costa das Dunas/RN, littoral potiguar region, where are invested the resources deriving from the Program of Development of Tourism in the northeast of Brazil (PRODETUR/NE). Making use of economy referencials, urban sociology and urban geography, as a possibility of a more consistent theoretical construction, capable to accomplish the sustainable development and sustainable tourism concepts amplitude, this work brings out an experience of interinstitucional cooperation, where it glimpses itself the possibility of implementation of a alternative development model, based on the sustainability principles

Morphometry and ultra-structure of the intestinal mucosa of broilers fed different additives

This study aimed at evaluating the effect of the use of different growth promoters on the morphometry and ultra-structure of the intestinal mucosa of 42-day-old broilers. A total number of 36 male Cobb broilers was distributed in a randomized experimental design with a 3 x 3 factorial arrangement, with 3 prebiotic and 3 probiotic sources in the feed, summing up 9 treatments, with 4 replicates each. There was a significant interaction (P<0.01) among the studied factor for villi height (VH) in all intestinal segments, and for crypt depth (CD) in the duodenum and the ileum. In the duodenum, higher villi were obtained in the control group, with the combination of B. subtilis and prebiotics, and with the single use of MOS+OA. No VH differences were observed between the control group and those fed prebiotics. In the jejunum, the highest villi were obtained with the use of the bacterial pool, followed by the control group, and by the use of B. subtilis. Higher villi were also obtained in the control group and in the groups fed MOS, when B. subtilis was used in combination with prebiotics, and when the bacterial pool was used individually or in combination with MOS. In the ileum, the highest villi were obtained with the individual use of B. subtilis, and when MOS+OA or MOS were individually used or in combination with the bacterial pool. As to duodenal CID, deeper crypts were observed in the control group and in those fed B. subtilis or MOS+OA. In the ileum, deeper crypts were also found in the control group and those fed B. subtilis. Deeper crypts were also found when the bacterial pool was individually used or in combination with MOS+OA, and with the individual use of MOS. It was concluded that the use of growth promoters was beneficial to Increase intestinal villi height when Bacillus subtilis was used in combination with prebiotics. The other growth promoters (MOS+OA, MOS, and bacterial pool), can be individually used in most situations. The tested growth promoters did not influence intestinal villi density.

Sources of human non-typhoid salmonellosis: a review

Salmonellosis is a worldwide disease caused by bacteria of the genus Salmonella. Currently, there are over 2,500 identified serovars of Salmonella. A reduced number of these serovars, about eighty, are implicated in most animals and human diseases. Most cases of salmonellosis in humans are associated with the consumption of contaminated food products such as beef, pork, poultry meat, eggs, vegetables, juices and other kind of foods. It may also be associated with the contact between humans and infected pet animals. Therefore, the chain of human salmonellosis is very complex and in most cases the origin of the infection is difficult to establish. The use of antimicrobial agents to treat and to prevent bacterial infections in humans and animals, as well as as growth promoters in animal production, has favoured the selection and transference of resistance genes between different bacteria, including Salmonella serovars. Many studies have confirmed the role of foods of animal origin as a source of multi drugresistant Salmonella serovars. For this reason, continuous surveillance of these pathogens along the food chain together with the responsible use of antimicrobial agents is necessary.

Carcass and cut yields and meat qualitative traits of broilers fed diets containing probiotics and prebiotics

This study evaluated the use of different probiotics, prebiotics and symbiotics on the quality of carcasses and meat of broiler chickens. One hundred and eight day-old Cobb male broilers were used (n=108) in a completely randomized design according to a 3x3 factorial, with 3 probiotics in the diet (no probiotics, probiotics 1, probiotics 2) and 3 prebiotics in the diet (no prebiotics, prebiotics 1, prebiotics 2). There were nine treatments with 4 replicates and 3 birds per replicate. The results showed that the carcass and cut yields, color (L* - lightness, a* - redness, and b* - yellowness), pH, cooking losses, shearing force and sensory analysis were not affected by the use of different growth promoters at 42 days of age. It was concluded that growth promoters supplemented to the diet did not affect the studied quantitative and qualitative parameters of the carcass and breast meat of broiler chickens.

Mananoligossacarídeos em dietas para frangos de corte

Objetivou-se avaliar dietas contendo mananoligossacarídeos (MOS) como aditivo alternativo aos promotores de crescimento por meio do estudo da morfometria do intestino e do desempenho de frangos de corte. Para tanto, 1280 pintos de corte foram distribuídos em delineamento inteiramente casualizado com quatro tratamentos (controle negativo, CN: dieta isenta de antibiótico; controle positivo, CP: dieta contendo antibiótico e duas dietas, MOS 1 e MOS 2, nas quais foram adicionadas ao CN duas fontes distintas de MOS) e oito repetições, sendo a unidade experimental composta por 40 aves. Para submeter as aves ao desafio sanitário, foi formulada uma dieta basal com milho, farelo de soja e farinha de carne e ossos. Adotou-se cama reutilizada, limpeza dos bebedouros duas vezes por semana e oferta semanal de água contaminada com cama. Foram avaliadas altura de vilo e profundidade de cripta do duodeno, jejuno e íleo, consumo da dieta, peso médio, ganho de peso e conversão alimentar das aves. Houve melhora na profundidade de cripta no jejuno e na altura de vilo no íleo das aves alimentadas com dietas contendo MOS. A adição de MOS, independente da fonte, resultou em melhor conversão alimentar em relação às aves do CN, sendo similares às aves do CP. Os mananoligossacarídeos podem ser utilizados como aditivo alternativo aos promotores de crescimento em dietas para frangos de corte, porém, dependendo da fonte, esta pode acarretar em pequenas diferenças no desempenho das aves.

Predição de promotores de Bacillus subtilis usando técnicas de aprendizado de máquina

One of the most important goals of bioinformatics is the ability to identify genes in uncharacterized DNA sequences on world wide database. Gene expression on prokaryotes initiates when the RNA-polymerase enzyme interacts with DNA regions called promoters. In these regions are located the main regulatory elements of the transcription process. Despite the improvement of in vitro techniques for molecular biology analysis, characterizing and identifying a great number of promoters on a genome is a complex task. Nevertheless, the main drawback is the absence of a large set of promoters to identify conserved patterns among the species. Hence, a in silico method to predict them on any species is a challenge. Improved promoter prediction methods can be one step towards developing more reliable ab initio gene prediction methods. In this work, we present an empirical comparison of Machine Learning (ML) techniques such as Na¨ýve Bayes, Decision Trees, Support Vector Machines and Neural Networks, Voted Perceptron, PART, k-NN and and ensemble approaches (Bagging and Boosting) to the task of predicting Bacillus subtilis. In order to do so, we first built two data set of promoter and nonpromoter sequences for B. subtilis and a hybrid one. In order to evaluate of ML methods a cross-validation procedure is applied. Good results were obtained with methods of ML like SVM and Naïve Bayes using B. subtilis. However, we have not reached good results on hybrid database

O objetivo deste trabalho foi avaliar a capacidade de microrganismos de manguezais para controlar a podridão radicular causada por Pythium aphanidermatum e para promover o crescimento em pepino hidropônico (Cucumis sativus). Avaliaram-se 19 microrganismos quanto ao controle da doença em mini-hidroponia. Os microrganismos mais promissores para esse fim - Gordonia rubripertincta SO-3B-2 e a mistura dos isolados G. rubripertincta SO-3B-2, MB-P3A-49, MB-P3-C68 e SO-3L-3, de Pseudomonas stutzeri, e Bacillus cereus AVIC-3-6 - foram, posteriormente, testados quanto à promoção de crescimento do pepineiro, em casa de vegetação. Microrganismos de manguezais podem ter importância funcional no controle biológico da podridão radicular causada por P. aphanidermatum e na promoção do crescimento do pepineiro cultivado em hidroponia. Os microrganismos G. rubripertincta SO-3B-2 e P. stutzeri MB-P3A-49 são promissores na promoção do crescimento das plantas não infestadas com o patógeno.

Estudo de técnicas para o tratamento alternativo de efluentes oleosos oriundos da industrialização da castanha de caju

An evaluation project was conducted on the technique of treatment for effluent oil which is the deriving process to improve cashews. During the evaluation the following techniques were developed: advanced processes of humid oxidation, oxidative processes, processes of biological treatment and processes of adsorption. The assays had been carried through in kinetic models, with an evaluation of the quality of the process by means of determining the chemical demand of oxygen (defined as a technique of control by means of comparative study between the available techniques). The results demonstrated that the natural biodegradation of the effluent ones is limited, as result using the present natural flora in the effluent one revealed impracticable for an application in the industrial systems, independent of the evaluation environment (with or without the oxygen presence). The job of specific microorganisms for the oily composite degradation developed the viability technique of this route, the acceptable levels of inclusion in effluent system of treatment of the improvement of the cashew being highly good with reasonable levels of removal of CDO. However, the use combined with other techniques of daily pay-treatment for these effluent ones revealed to still be more efficient for the context of the treatment of effluent and discarding in receiving bodies in acceptable standards for resolution CONAMA 357/2005. While the significant generation of solid residues the process of adsorption with agroindustrial residues (in special the chitosan) is a technical viable alternative, however, when applied only for the treatment of the effluent ones for discarding in bodies of water, the economic viability is harmed and minimized ambient profits. Though, it was proven that if used for ends of I reuse, the viability is equalized and justifies the investments. There was a study of the photochemistry process which have are applicable to the treatment of the effluent ones, having resulted more satisfactory than those gotten for the UV-Peroxide techniques. There was different result on the one waited for the use of catalyses used in the process of Photo. The catalyses contained the mixing oxide base of Cerium and Manganese, incorporated of Potassium promoters this had presented the best results in the decomposition of the involved pollutants. Having itself an agreed form the gotten photochemistry daily paytreatment resulted, then after disinfection with chlorine the characteristics next the portability to the water were guarantee. The job of the humid oxidation presented significant results in the removal of pollutants; however, its high cost alone is made possible for job in projects of reuses, areas of low scarcity and of raised costs with the capitation/acquisition of the water, in special, for use for industrial and potable use. The route with better economic conditions and techniques for the job in the treatment of the effluent ones of the improvement of the cashew possesses the sequence to follow: conventional process of separation water-oil, photochemistry process and finally, the complementary biological treatment

Crenças de Educadoras de Creche Sobre Temperamento e Desenvolvimento de Bebês

O objetivo desta investigação foi verificar o julgamento de educadoras de creche sobre os fatores que causam e/ou influenciam o temperamento e o desempenho de bebês. Vinte e uma educadoras foram entrevistadas a respeito de cada um dos 90 bebês de 4 a 24 meses sob seus cuidados, seguindo um roteiro semi-estruturado. Os resultados mostram que (a) as crenças das educadoras são predominantemente ambientalistas, isto é, que as educadoras atribuem influência significativa do ambiente no temperamento e desempenho dos bebês, e (b) que elas subestimam o seu papel de promotoras do desenvolvimento das crianças. A necessidade de se conhecer as crenças das educadoras para a eleboração de programas de treinamento eficazes é enfatizada.
