However, some authors are critical to the strategic maps derived from the BSC due to: (i) the relationship of causes and effects are one-way, (ii) the model is static and does not express the temporality, and (iii) the fact that its indicators capture only past facts. Given that actors, resources, and processes interact in a scenario for the execution of a strategic plan, it seems to be an interesting idea to apply modeling and simulation techniques to understand this dynamics. Complementarily, the great uncertainty of the variables involved in this scenario works as a strong driver to the adoption of qualitative representations instead of a precise numerical model. Thus, the Qualitative Modeling technique is studied in this research, exploring the variables values represented by intervals and distinct points in their respective domains. Two qualitative models were built, one related to the scenarios for strategic planning and other for representing the strategic map of an organization. Simulations on the models were conducted in order to enable: (i) a conceptual study of the relations between the components of the plan, showing how modeling and qualitative simulations can help in maintaining their alignment; (ii) the anticipation by the strategic level of the organization of problems arising from assumptions about the values of variables; and (iii) promoting organizational learning from the sensemaking process triggered by the analysis of the simulation results. A case study was carried out on the institutional strategic planning from the Brazilian General Attorney in order to enlighten the benefits from the proposed approach. / O Balanced Scorecard (BSC) ?? uma metodologia amplamente adotada para medir e monitorar a implementa????o da estrat??gia organizacional. No entanto, alguns autores s??o cr??ticos quanto aos mapas estrat??gicos oriundos do BSC por conta: (i) das rela????es de causa e efeito serem unidirecionais, (ii) de o modelo ser est??tico e n??o expressar temporalidade, e (iii) de seus indicadores de captarem apenas o passado. Visto que em um cen??rio de execu????o de um plano estrat??gico interagem atores, recursos e processos, a ideia de se aplicar t??cnicas de modelagem e simula????o para se entender essa din??mica ?? atrativa. A grande incerteza das vari??veis envolvidas neste cen??rio funciona como um forte incentivo para a ado????o de representa????es qualitativas em vez de um modelo num??rico preciso. Assim, a t??cnica Modelagem Qualitativa foi ?? estudado nesta pesquisa, explorando os valores das vari??veis representadas por intervalos e pontos distintos em seus respectivos dom??nios. Dois modelos qualitativos foram constru??dos, um relacionado com os cen??rios de planejamento estrat??gico e outro para representar o mapa estrat??gico de uma organiza????o. Simula????es sobre os modelos foram conduzidas a fim de permitir: (i) a combina????o de uma reflex??o concetual sobre as rela????es entre os componentes do plano, mostrando como a modelagem e simula????es qualitativos podem ajudar na manuten????o do seu alinhamento; (ii) que o n??vel estrat??gico da organiza????o antecipe problemas decorrentes de suposi????es sobre os valores das vari??veis; e (iii) a aprendizagem organizacional do processo de tomada de sentido desencadeada pela an??lise dos resultados da simula????o. Um estudo de caso foi realizado no planejamento estrat??gico institucional do Minist??rio P??blico Federal, a fim de se evidenciar os benef??cios da abordagem proposta.

Therefore this study had as objective to evaluate the influence of psychological gender profile of men integrant of a Military Police Battalion of the State of Piau?? about their levels of stress and physical fitness health-related. Method: the study is characterized as descriptive, quantitative, observational and correlational and was developed with 42 members of the Tactical Actions Group of the military police of the State of Piau??, all male. As data collection instruments were used the Male Gender Schemas' Inventory of Self-concept - IMEGA to evaluate the psychological gender profile and the Factorial Model of Stress - MFE to evaluate the stress level, healthrelated physical fitness was evaluated by applying motor tests as flexibility, strength/ localized muscular endurance (abdominal and elbow flexion), 12-minute test, in addition to these was held also the evaluation of fat % with skinfold method through the 7 site equation proposed by Jackson and Pollock. The results demonstrated that soldiers presented only two typological gender groups, Isoesquem??ticos (61%) and Heteroesquem??ticos Male (39%), about the results of motor tests for flexibility was 37.4 ?? 8.52 centimeter, abdominals was 49.75 ?? 6.68 repetitions per minute, elbows flexion was 43 ?? 11.45 repetitions, VO2max was 45.22 ?? 3.45 ml (kg/min) -1 and fat % was 11.65 ?? 4.02. As for the stress, the soldiers did not show high levels of stress. Conclusions: Although the results of the psychological profile of Gender are consistent with the characteristics of the profession of the subjects of the sample, it was found that there is no influence of the psychological profile of genre on physical fitness levels or about stress levels. / ?? fato comprovado que a pr??tica de atividade f??sica ?? eficaz no combate ao estresse, no entanto com cria????o do Modelo Interativo, proposto a fim de avaliar os esquemas de g??nero do auto conceito, classificando os sujeitos em tr??s grupos principais, Heteroesquem??ticos Masculino, Isoesquematicos e Hetroesquematicos Femininos onde h?? uma associa????o entre a consist??ncia comportamental de acordo com o grupo a que perten??a, ?? relevante que se fa??a a correla????o entre perfil psicol??gico de g??nero, aptid??o f??sica e estresse para se compreender atitudes e comportamentos de diferentes sujeitos diante de situa????es diversas.

The indiscriminate use of chemical products for its control has generated several negative effects and in this context, studies involving the fungus Metarhizium spp. for biological control of ticks have shown great importance. The present study evaluated the virulence of 11 isolates of Metarhizium spp. for engorged females, eggs and larvae of R. microplus and also the conidiogenesis potential of the same isolates and their relationship with virulence. Single point of inoculum and cultivation between slide and coverslip were performed to evaluate the macro and micromorphology of the isolates. During the bioassay using engorged females, the effects of fungi on reproductive parameters were evaluated by analyzing the control percentage of each isolate after treatment by immersion of females in suspensions of 107 and 108 conidia / mL. The virulence of the isolates for eggs and larvae was evaluated by observing the hatch rate and mortality, respectively, after treatment with aqueous suspensions of Metarhizium spp. at concentrations of 105, 106, 107 and 108 conidia / mL. The LC50 and CL90 of each isolate for larvae were also calculated on the 25th day after treatment. To calculate the conidiogenesis of the isolates, three random cuts of 1.256 cm2 of area of each plate containing fungal conidia of 14 days of culture were made, then stirred in 1 ml of distilled water solution and 0.1% tween 80 and one aliquot of this suspension was quantified using a Neubauer chamber and optical microscope. Parametric data were analyzed by analysis of variance (ANOVA) followed by Tukey test and non-parametric by Kruskal Wallis test followed by Student-Newman-Keuls (SNK) with significance level of 5% through free software R Studio Version 0.99 .903 and the "agricolae" package (Statistical Procedures for Agricultural Research), version 1.2-4. In addition, multivariate statistics were applied using Principal Component Analysis (PCA) for parameters of engorged females. The macro and micromorphological analysis of the isolates tested were compatible with those described in the literature for Metharizium spp. In general, the results were directly proportional to the concentrations that were tested and the isolates ARSEF 729 of Metarhizium anisopliae and ARSEF 3643 of Metarhizium anisopliae senso latu, presented the best results for R. microplus females, eggs and larvae, proving to be good candidates for future studies, whereas the isolate ARSEF 2211 of Metarhizium anisopliae senso latu demonstrated low virulence for all stages. The conidiogenesis of the different isolates tested varied a lot and no relation between conidia production and virulence was observed. The present study made possible the selection of isolates of Metarhizium spp. with high virulence for several stages of life of the R. microplus tick as well as isolates with high conidia production and their relationship with virulence, emphasizing the importance of studies to select suitable isolates for future use in formulations for biological control in the field. / O parasitismo causado por Rhipicephalus microplus, conhecido popularmente como carrapato dos bovinos, acarreta diversos preju?zos para a pecu?ria brasileira. O uso indiscriminado de produtos qu?micos para o seu controle tem gerado diversos efeitos negativos e nesse contexto, estudos envolvendo o fungo Metarhizium spp. para controle biol?gico de carrapatos tem demonstrado grande import?ncia. O presente estudo avaliou a virul?ncia de 11 isolados de Metarhizium spp. para f?meas ingurgitadas, ovos e larvas de R. microplus e tamb?m o potencial de conidiog?nese dos mesmos isolados e a sua rela??o com a virul?ncia. Pontos ?nicos de in?culo e microcultivo entre l?mina e lam?nula foram realizados a fim de avaliar a macro e micro morfologia dos isolados. Durante o bioensaio utilizando f?meas ingurgitadas, foram avaliados os efeitos dos fungos sobre os par?metros reprodutivos atrav?s da an?lise do percentual de controle de cada isolado ap?s o tratamento por imers?o das f?meas em suspens?es aquosas de 107 e 108 con?dios/mL. A virul?ncia dos isolados para ovos e larvas foi avaliada atrav?s da observa??o da taxa de eclos?o e mortalidade, respectivamente, ap?s tratamento com suspens?es aquosas nas concentra??es de 105, 106, 107 e 108 con?dios/mL. Tamb?m foi calculada a CL50 e CL90 de cada isolado para larvas no vig?simo quinto dia ap?s o tratamento. Para calcular a conidiog?nese dos isolados, foram feitos tr?s recortes aleat?rios de 1,256 cm2 de ?rea de cada placa contendo con?dios f?ngicos de 14 dias de cultivo, em seguida foram agitados em 1mL de solu??o de ?gua destilada e tween 80 a 0,1% e uma al?quota desta suspens?o foi quantificada com o auxilio de c?mara de Neubauer e microsc?pio ?ptico. Os dados param?tricos foram avaliados pela an?lise de vari?ncia (ANOVA) seguida do teste de Tukey e os n?o param?tricos pelo teste de Kruskal Wallis seguido de Student-Newman-Keuls (SNK) com n?vel de signific?ncia de 5% atrav?s do software livre R Studio Vers?o 0.99.903 e o pacote ?agricolae? (Statistical Procedures for Agricultural Research), vers?o 1.2-4. Adicionalmente foi aplicada estat?stica multivariada mediante a An?lise de Componentes Principais (ACP) para par?metros de f?meas ingurgitadas. A an?lise macro e micromorfol?gica dos isolados testados se mostrou compat?vel com as descritas na literatura para Metharizium spp. De maneira geral, os resultados se apresentaram diretamente proporcionais ?s concentra??es que foram testadas e os isolados ARSEF 729 de Metarhizium anisopliae e ARSEF 3643 de Metarhizium anisopliae senso latu, apresentaram os melhores resultados para f?meas, ovos e larvas de R. microplus, demonstrando ser bons candidatos para estudos futuros. O isolado ARSEF 2211 de Metarhizium anisopliae senso latu demonstrou baixa virul?ncia para todos os est?gios. A conidiog?nese dos diferentes isolados testados se mostrou muito variada e n?o apresentou nenhuma rela??o com a virul?ncia dos mesmos. O presente estudo possibilitou a sele??o de isolados de Metarhizium spp. com alta virul?ncia para os diferentes est?gios de vida do carrapato R. microplus bem como isolados com alta produ??o de con?dios, ressaltando a import?ncia de estudos que visem selecionar isolados adequados para serem utilizados futuramente em formula??es para controle biol?gico a campo.

Initially, an exploratory study was done with students of the Organic Farming high school and some school staff, using short videos, visits to the College's campus to observe the school?s garbage, and a guided tour on the city's garbage deposit as elements of motivation. After these activities, a survey was done of the participants? environmental awareness, through free demonstrations via reports about what was seen and discussed in these activities, followed by a brainstorming with presentation of possible solutions to the school problems. Further, a semistructurade questionnaire was applied with open questions, in which the interviewee had freedom to write about the proposed issue, and pre-formulated closed questions, whereby highlighted the best answers which represented their opinion. 65 students and members of staff filled questionnaire up. The questionnaires were analyzed statistically by dispersion and by the results, it was noted that the arguments of the interviewers were typically Cartesian. This reductive vision limits their ability to see the problem in a systemic way, because they are arguments that show a mechanistic design of the universe, whose laws, according to this conception, could be in theory, objectively learned through scientific procedures. These structures of thought are not exclusive of interviewees, particularly among students. They were certainly consolidated in family conviviality, neighborhood relationship and in other groups of relationship, including the school. Within this perspective, it is understood that EE has the purpose to disarm these structures of thought that perceive the relationship man/nature within a binary mechanics in formal logic and rationalist. This research used a special population that can be considered as been representative of the student elite of the country. So, they are not generalized conclusions about the set of the Brazilian population. If this premise is true, this finding is that the situation is worrying since the vast majority of Brazilians surely has an instructional level lower than the interviewees in this research, supporting the argument that the results obtained are representative and mirror the Brazilian reality, what sustain the urgency of to implement EE in the school?s curriculum across the country. The analysis of the results obtained in this research allowed an interpretation and a more precise and detailed diagnosis of the EE framework in its most varied aspects under CTUR. As a result, could be identified misconceptions and faults, resulted primarily from a shallow approach of the EE at the institution. Was given a set of epistemological suggestions, to assist to the institution's Pedagogical Political Project and to the effective implementation of EE, understanding that the teacher's target is not only complement this suggestion, but also find answers to the questions that issue evokes and thus, propose alternative ways of thinking and acting. / O trabalho teve por objetivo investigar a contribui??o de pr?ticas de Educa??o Ambiental (EA), no projeto pedag?gico do Col?gio T?cnico da Universidade Federal Rural do Rio de Janeiro (CTUR). Inicialmente, foi feito um estudo explorat?rio com os alunos do terceiro ano do Ensino M?dio em Agropecu?ria Org?nica e uma parte dos funcion?rios da escola, utilizando-se, como elementos de motiva??o, v?deos de curta dura??o, visita pelas instala??es do col?gio para observa??o de um problema ambiental espec?fico - o lixo comum, e visita guiada ao dep?sito de lixo da cidade de Serop?dica. Ap?s essas atividades, foi feito um levantamento da percep??o ambiental dos participantes, mediante manifesta??es livres por meio da elabora??o de relat?rios do que foi visto e discutido nas atividades, seguido de uma exposi??o de id?ias, com apresenta??o de solu??es poss?veis para o problema do lixo escolar. ? continua??o, foi aplicado um question?rio semiestruturado com quest?es abertas, nas quais o entrevistado manifestou-se livremente por escrito sobre o tema proposto, e com quest?es fechadas pr?-formuladas, mediante as quais assinalava respostas que melhor representavam sua opini?o. Responderam ao question?rio 65 entrevistados, entre estudantes e funcion?rios. Os question?rios foram analisados estatisticamente por dispers?o e pelos resultados, observou-se que os argumentos dos entrevis tados foram tipicamente cartesianos. Essa vis?o reducionista limita a capacidade de enxergar o problema de uma forma sist?mica, pois s?o argumentos que apresentam uma concep??o mecanicista do universo, cujas leis, de acordo com essa concep??o, poderiam em tese, ser aprendidas objetivamente mediante procedimentos cient?ficos. Essas estruturas de pensamento n?o s?o exclusivas dos entrevistados, sobretudo dos estudantes. Elas foram certamente consolidadas no conv?vio familiar, nas rela??es de vizinhan?a e nos demais grupos de relacionamento, inclusive na escola. Dentro desta perspectiva, entende-se que ? EA cabe a tarefa de desarmar essas estruturas de pensamento que percebem a rela??o homem/natureza dentro de uma mec?nica bin?ria na l?gica formal e racionalista. Esta pesquisa serviu-se de uma popula??o especial que pode ser considerada representativa da elite discente do pa?s. Portanto, n?o se tratam de conclus?es generalizadas sobre o conjunto da popula??o brasileira. Se essa premissa ? verdadeira, a constata??o ? de que a situa??o ? preocupante, pois a grande maioria dos brasileiros seguramente encontra-se em condi??es instrucionais menos privilegiadas do que os participantes dessa pesquisa, sustentando o argumento de que os resultados obtidos s?o representativos e espelham a realidade brasileira, o que subsidiaria a prem?ncia na implementa??o da EA no curr?culo das escolas de todo o pa?s. A an?lise dos resultados obtidos na pesquisa permitiu uma interpreta??o e um diagn?stico mais preciso e pormenorizado do quadro da EA nos seus mais variados aspectos no ?mbito do CTUR. Como resultado, puderam-se identificar equ?vocos e falhas, decorrente principalmente de uma abordagem superficial da EA na institui??o. Foi dado um conjunto de sugest?es, de car?ter epistemol?gico, para auxiliar no Projeto Pol?tico Pedag?gico da institui??o e na implementa??o efetiva da EA, entendendo que a tarefa do professor ?, n?o s? complementar essa sugest?o, como tamb?m encontrar respostas ?s provoca??es que o tema evoca e, assim, propor formas alternativas de pensamento e de atua??o.

The soil classification is the basis for determining the potential use of the land, ie, guide the sustainable use of the same. For this situation, it is known that many factors corroborate the frame. Among these the human factor has great weight in this matter because, Survey and Soil Classification (LCSs) are present on curricular content for training of Agronomists, Forestry Engineers, etc.., and scholars and authorities in the field of Soil Science have signaled that the Higher Education Institutions (specifically undergraduate) come crashing in training these professionals supposedly trained and qualified to the activity of LCSs, considering that the courses that form such professionals invariably advocated among other things "solid scientific general and professional ... "what prescribes the contents of their curricular chord in the National Curriculum Guidelines. Informally today, teachers generally do mind that the problem lies in the structure of undergraduate courses regarding aspects: design of a workload of disciplines; literature indicated in ement?rios; disciplines sequence prerequisites; opportunity of additional knowledge through elective courses, etc.. Thus, sensing data bring to literature that deal with the subject, aimed this work was to analyze the conditions for teaching of LCSs course of Forestry's IFMT - Campus C?ceres through its Political-Pedagogical Project (PPP) as all the above aspects. This research is exploratory, Documentary and Quanti-qualitative nature. Included in the questionnaire data collection and content analysis for inferences. The inferences are that the references (data obtained from educators in the field of Soil Science of the five geographical regions through a questionnaire) indicate that the PPP course has limitations that may affect the teaching-learning LCSs and achieve, in this regard (themes mentioned), the professional profile designed by the course concerning "solid scientific and professional general enabling absorb and develop technology." The limitations were: inadequate sizing workload in disciplines that include LCSs and related activities; literature indicated in these ement?rio not include modern features with the potential to collaborate with a better education, sequence of disciplines inappropriate prerequisites discipline that includes these activities and, lack of opportunity for complementation of knowledge related to these themes via list of electives. Given the paucity of information in the literature that addresses on the subject, the data generated will assist both in the construction and / or reformulation of PPP courses in general as well as instigating research on the topic. / Apesar de toda produ??o agropecu?ria que saem dos solos brasileiros, pujan?a do agroneg?cio que se noticia, a maior parte dos solos do Pa?s n?o est?o classificados a n?vel adequado para utiliza??o do agricultor; ou melhor, dizendo, as propriedades agr?colas e florestais, em sua maioria, n?o possuem um mapeamento de seus solos, logo, majoritariamente produtores e profissionais tecnicamente atuantes nestas propriedades n?o possuem um conhecimento detalhado dos tipos de solos que se t?m trabalhado. A classifica??o dos solos serve de base para determina??o do potencial de uso das terras, ou seja, norteiam a utiliza??o sustent?vel das mesmas. Para esta situa??o, sabe-se que muitos fatores corroboram com o quadro. Dentre estes o fator humano tem grande peso nesta quest?o; pois, Levantamento e Classifica??o de Solos (LCSs) s?o conte?dos presentes nas matrizes curriculares para forma??o de Engenheiros Agr?nomos, Engenheiros Florestais, etc.; e, estudiosos e autoridades da ?rea de Ci?ncia do Solo t?m sinalizado que as Institui??es de Ensino Superior (especificamente cursos de gradua??o) v?m falhando na forma??o desses profissionais pressupostamente capacitados e habilitados para a atividade de LCSs; tendo em vista que, os cursos que formam tais profissionais, invariavelmente, preconizam dentre outras coisas ?s?lida forma??o cientifica e profissional geral...? daquilo que prescreve os conte?dos de suas matrizes curriculares em acorde com as Diretrizes Curriculares Nacionais. Informalmente na atualidade, docentes em geral cogitam que o problema est? na estrutura dos cursos de gradua??o quanto aos aspectos: dimensionamento de carga hor?ria de disciplinas; bibliografia indicada em ement?rios; sequencia de disciplinas pr?-requisitos; oportunidade de complementa??o de conhecimentos via disciplinas optativas, etc. Dessa forma, intuindo trazer dados ? literatura que versem sobre o assunto, objetivou-se com este trabalho analisar as condi??es para atividades de ensino de LCSs do curso de Engenharia Florestal do IFMT - Campus C?ceres atrav?s de seu Projeto Pol?tico-Pedag?gico (PPP) quanto aos aspectos supramencionados. A presente pesquisa ? Explorat?ria, Documental e de natureza Quanti-qualitativa. Incluiu o Question?rio na coleta dos dados e a An?lise de Conte?do para as infer?ncias. As infer?ncias s?o de que as refer?ncias (dados obtidos junto a educadores da ?rea de Ci?ncia do Solo das cinco regi?es geogr?ficas brasileiras atrav?s de question?rio) indicam que o PPP do curso apresenta limita??es que podem comprometer o ensino-aprendizado de LCSs e alcan?ar, neste quesito (tem?ticas mencionadas), o perfil profissional projetado pelo curso concernente a ?s?lida forma??o cient?fica e profissional geral que possibilite absorver e desenvolver tecnologia?. As limita??es encontradas foram: dimensionamento inadequado de carga hor?ria em disciplinas que contemplam LCSs e atividades correlatas; bibliografia indicada no ement?rio destas n?o incluem recursos modernos com potencial de colaborar com uma melhor forma??o; sequ?ncia inapropriada de disciplinas pr?-requisitos a disciplina que contempla estas atividades; e, inexist?ncia de oportunidade para complementa??o dos conhecimentos relacionados a tais tem?ticas via rol de disciplinas optativas. Dado a escassez de informa??es na literatura que trate sobre o assunto, os dados gerados poder?o auxiliar tanto na constru??o e/ou reformula??o de PPP de cursos em geral bem como instigar pesquisas sobre a tem?tica.

In Brazil, there are 3.5 million workers aged between 5 and 17. This exploitation practice constitutes a serious social problem, including of Public Health, since these workers are exposed to a wide range of risks, such as those related to health, physical integrity and even to life, which may cause them to become sick adults and/or interrupt their lives prematurely. Therefore, this research aims to investigate the relationship between the frequency of child labor in the age group of 10 to 13 years and some socio-economic indicators. It is a quantitative research in an ecological study whose levels of analysis are the Brazilian municipalities grouped in 161 regions, defined from socioeconomic criteria. The dependent variable of this study was the prevalence of child labor in the age group of 10 to 13 years. The independent variables were selected after a correlation between the 2010 Census of child labor in the age group of 10 to 13 years and secondary data had been conducted, adopting two main independent variables: funds from the Family Allowance Program (PBF) per 1,000 inhabitants and Funds from the Child Labor Eradication Program (PETI) per a thousand inhabitants. Initially, it was conducted a descriptive analysis of the variables of the study, then, a bivariate analysis, and the correlation matrix was built. At last, the Multiple Linear Regression stratified analysis was performed. The results of this survey indicate that public policies , like the Bolsa Familia Program Features per 1000 inhabitants and Resources Program for the Eradication of Child Labour to be allocated to municipalities with HDI < 0.697 represent a decrease in the rate of child labor ; These programs have the resources to be invested in municipalities with HDI > = 0.697 have no effect on the rate of child labor. Other adjustment variables showed significance, among these the municipal Human Development Index (IDH), years of schooling at 18 years of age, illiteracy at 15 years of age or more, employees without employment contract at 18 years of age and the Gini Index. It is understood that the child labor issue is complex. The problem is associated, although not restricted to, poverty, the social exclusion and inequality that exist in Brazil, but other factors of cultural and economic nature, as well as of organization of production, also account for its aggravation. Fighting child labor involves a wide intersectoral articulation, shared and integrated with several public policies, among them health, sports, culture, agriculture, labor and human rights, with a view to guaranteeing the integrality of the rights of children and adolescents in situation of labor and of their respective families / A Organiza??o Internacional do Trabalho (OIT) estima que haja cerca de 118 milh?es de crian?as em todo o mundo submetidas ao trabalho infantil. No Brasil, h? 3,5 milh?es de trabalhadores entre 5 e 17 anos. Esse exerc?cio de explora??o constitui um grave problema da sociedade, inclusive de Sa?de P?blica, j? que esses trabalhadores est?o expostos a uma gama de riscos, quais sejam ? sa?de, ? integridade f?sica e at? ? vida, podendo torn?-los adultos doentes e/ou interrompendo precocemente suas vidas. Diante do exposto, esta pesquisa tem como objetivo investigar a rela??o entre a frequ?ncia de trabalho infantil na faixa et?ria de 10 a 13 anos e alguns indicadores socioecon?micos. Trata-se de uma pesquisa quantitativa em um desenho ecol?gico cujos n?veis de an?lise s?o os munic?pios brasileiros agrupados em 161 regi?es, definidas a partir de crit?rios socioecon?micos. A vari?vel dependente deste estudo foi a preval?ncia de trabalho infantil na faixa et?ria de 10 a 13 anos. As vari?veis independentes foram selecionadas ap?s realizada uma correla??o entre o Censo de 2010 do trabalho infantil na faixa et?ria de 10 a 13 anos e dados secund?rios, adotando duas vari?veis independentes principais: recursos do Programa Bolsa Fam?lia (PBF) por 1000 habitantes e Recursos do Programa de Erradica??o do Trabalho Infantil (PETI) por mil habitantes. Foi realizada inicialmente uma an?lise descritiva das vari?veis do estudo, posteriormente, uma an?lise bivariada, e constru?da a matriz de correla??o. Por fim, foi feita a an?lise de Regress?o Liner M?ltipla. Foram constru?dos dois modelos de Regress?o. O primeiro modelo, no qual os recursos do PBF ? a variav?l independente principal, explica 57,8% de toda a varia??o do trabalho infantil e a equa??o final permite inferir que a cada 100 reais de recursos do PBF alocados produz uma diminui??o de 1,4% na taxa de trabalho infantil na faixa et?ria de 10 a 13. No segundo, no qual os recursos do PETI explicam 58,8% de todo o modelo, constatou-se que a cada R$ 100 reais investidos, a taxa de trabalho infantil diminui em 2,16%. Outras vari?veis de ajuste mostraram signific?ncia, entre elas o IDH municipal, anos de Estudos aos 18 anos, analfabetismo em 15 anos ou mais, empregados sem carteira com 18 anos e o ?ndice de Gini. Compreende-se que a quest?o do trabalho infantil ? complexa. O problema est? associado, embora n?o esteja restrito ? pobreza, ? desigualdade e ? exclus?o social existentes no Brasil, mas h? outros fatores de natureza cultural, econ?mica e de organiza??o da produ??o, respondem tamb?m pelo seu agravamento. Para enfretamento do trabalho infantil necessita de uma ampla articula??o intersetorial compartilhada e integrada com diversas pol?ticas p?blicas entre elas sa?de, esporte, cultura, agricultura, trabalho e direitos humanos, tendo, como horizonte, a garantia da integralidade dos direitos de crian?as e adolescentes em situa??o de trabalho e de suas respectivas fam?lias

O principal objetivo deste trabalho consiste em propor um modelo de direcionamento estrat?gico capaz de envolver o aprimoramento dos procedimentos legislativos, atendendo os anseios da sociedade com garantias de perenidade nas a??es administrativas da Assembleia Legislativa do Rio Grande do Norte. Para tanto, utilizou-se de question?rios estruturados a fim de se realizar um diagn?stico interno e externo da situa??o atual e das perspectivas futuras do Parlamento Potiguar, utilizando-se para isso requisitos como imagem, desempenho, situa??o atual de seu planejamento estrat?gico e vis?o de futuro. Esses question?rios foram aplicados em tr?s categorias de p?blico: servidores, deputados estaduais e sociedade. A t?cnica utilizada para a an?lise dos question?rios foi a an?lise de conte?do cujos resultados, comparados entre si e com a an?lise do planejamento estrat?gico 2017-2018, contribu?ram para a elabora??o de um mapeamento de tend?ncias, o qual foi analisado com foco na elabora??o da proposta e foi submetido ? valida??o por meio de um Grupo Focal que executa o planejamento estrat?gico em vigor na ALRN. Da an?lise dos question?rios, concluiu-se que o gerenciamento por diretrizes ? necess?rio para que a cultura estrat?gica possa se perpetuar na Casa Legislativa, que hoje possui baixa intera??o com a sociedade, apresentando baixa efici?ncia, efic?cia e efetividade no desempenho das atividades final?sticas, que s?o os processos legislativos. Com isso, houve uma preocupa??o voltada para o aumento da credibilidade, com maior participa??o popular, trazendo elementos de ?tica, transpar?ncia e comunica??o que devem estar alinhados com um direcionamento estrat?gico adequado. Pretende-se com a cria??o desta proposta contribuir para a melhoria da gest?o legislativa com foco nos conceitos da Nova Gest?o P?blica e com a inser??o de elementos de accountability, visando evoluir o Poder Legislativo no Estado do Rio Grande do Norte e garantir a melhoria de qualidade das pol?ticas p?blicas e da qualidade da Lei. Considerando que para o caso concreto a mensura??o dos resultados s? poder? ser realizada em caso de implanta??o efetiva pela Mesa Diretora da Casa, a presente pesquisa constitui na proposta de modelo de interven??o. / The present proposal for intervention examines the issue of strategic planning focusing on an institution of the Legislative Branch within on a State Public Administration. The main objective of this paper is to propose a model of strategic orientation capable of involving the improvement of the legislative procedures, meeting the society's longings with guarantees of continuity in the administrative actions of the Legislative Assembly of Rio Grande do Norte. Therefore, structured questionnaires were used in order to make an internal and external diagnosis of the current situation and future perspectives of the Rio Grande do Norte Parliament, using for such requirements such as image, performance, current situation of its strategic planning and vision of future. These questionnaires were used for three categories: public server, parliamentarians and society. The technique used to analysis the questionnaires was the content analysis whose results, compared to each other and to the analysis of the 2017-2018 strategic planning, contributed to the development of a trend mapping, which was analyzed with a focus on the elaboration of the proposal which was submitted to validation through a Focal Group that executes the strategic planning in force in the ALRN. From the analysis of the quiz, it was concluded that management by guidelines is necessary so that the strategic culture can be perpetuated in the Rio Grande do Norte Legislative Assembly, which today has low interaction with society, presenting low efficiency, effectiveness and effectiveness in the performance of the finalistic activities, which are legislative processes. In this way, there was a concern focused on increasing credibility, with greater popular participation, bringing elements of ethics, transparency and communication that should be aligned with an appropriate strategic direction. The aim of this proposal is to contribute to the improvement of legislative management focused on the concepts of New Public Management and the insertion of elements of accountability, aiming to evolve the Legislative Branch in the State of Rio Grande do Norte and ensuring improvement quality of public policies and the quality of the Law. Whereas for the case the measurement of the results can only be performed in case of effective implementation by the Board of Directors of the ALRN, the present research constitutes a proposal of intervention.

This is a qualitative, descriptive and representational research aiming to discover how the professional nurses represent the very psychological distress from work in the hospital environment. Aided and supported by specific objectives of identifying factors that generates this suffering and strategies for defense and confronting these professionals in the hospital. 22 nurses participated in this research, officials of the University Hospital Onofre Lopes, located in the city of Natal / RN, with length of service in the institution more than one year and less than five, and they accepted, by signing the Term of Free and Informed Consent, participate in the study. We use plurimethodological approach: a questionnaire, a semi-structured interview and the design-story with a theme adapted from Trinca with the support of the Theory of Social Representations and that nurses do in their psychological distress of the Central Core. We reviewed the data from the results generated by the ALCESTE software, based on hierarchical categorization downward, leading seven classes used as categories: Work process: completeness vs. incompleteness; labor contradiction of the nurse; qualitative aspects of interpersonal relationships; hospital surveillance: Challenges, muteness and neglect; Expectations, conflicts and feelings in the work process; Leisure: the other side of the work process, and Suffering generating aspects of in the work process. We consider the analysis of quarters generated by the program, which SLQ houses in the central core of the representations; the SRQ and the DLQ the intermediaries elements and the DRQ the peripheral elements that nurses do in their psychological distress. We analytically adequate results in the three belonging dimensions of social representations: the Subjectivity, the Intersubjectivity and Trans-subjectivity. We infer that the interpersonal relationship, the extra work, the deviation in the role of nurse show themself as the factors responsible for psychological distress of it. In that sense, the central core of SR of this profession is based on the level of trans-subjectivity and understood as a Social Representation controversy / Entendemos que a insatisfa??o advinda da falta de cren?a nas possibilidades de mudan?a do contexto laboral que originam dificuldades para a realiza??o profissional resulta no sofrimento ps?quico do profissional que, atualmente se insere no contexto da sa?de mental. Trata-se de uma pesquisa qualitativa, descritiva e representacional objetivando apreender como os profissionais enfermeiros representam o pr?prio sofrimento ps?quico decorrente do trabalho no ambiente hospitalar. Auxiliado e amparado pelos objetivos espec?ficos de identificar fatores geradores deste sofrimento e de identificar estrat?gias de defesa e enfrentamento desses mesmos profissionais em ambiente hospitalar. Participaram desta pesquisa 22 enfermeiros, funcion?rios do Hospital Universit?rio Onofre Lopes, situado no munic?pio de Natal/RN, com tempo de servi?o na institui??o maior que um ano e menor que cinco e que aceitaram, mediante a assinatura do Termo de Consentimento Livre e Esclarecido, participar do estudo. Utilizamos abordagem plurimetodol?gica: um question?rio, uma entrevista semi-estruturada e o Desenho-est?ria com tema adaptado de Trinca com o suporte da Teoria das Representa??es Sociais e a que os enfermeiros fazem do seu sofrimento ps?quico do N?cleo Central. Analisamos os dados a partir dos resultados gerados pelo software ALCESTE com base na categoriza??o hier?rquica descendente, derivando sete classes usadas como categorias: processo de trabalho: completude vs. incompletude; antinomia laboral do enfermeiro; aspectos qualitativos do relacionamento interpessoal; vigil?ncia hospitalar: desafios, silenciamento e neglig?ncia; expectativas, conflitos e sentimentos no processo de trabalho; lazer: o outro lado do processo de trabalho e, aspectos geradores de sofrimento no processo de trabalho. Consideramos pela an?lise dos quadrantes gerados pelo programa, que o Quadrante Superior Esquerdo abriga o n?cleo central das representa??es; o Quadrante Superior Direito e o Quadrante Inferior Esquerdo os elementos intermedi?rios e o Quadrante Inferior Direito os elementos perif?ricos que os enfermeiros fazem do seu sofrimento ps?quico. Adequamos analiticamente os resultados nas tr?s dimens?es de pertencimento das representa??es sociais: a Subjetividade, a Inter-subjetividade e a Trans-subjetividade. Inferimos que a rela??o interpessoal, a sobrecarga de trabalho, o desvio da fun??o do enfermeiro apresentou-se como os fatores respons?veis pelo sofrimento ps?quico do mesmo. Nesse sentido, o n?cleo central da representa??o social desta categoria profissional, insere-se no n?vel da trans-subjetividade e est? compreendida como uma Representa??o Social Pol?mica

Formulada pelo l?gico polon?s Roman Suszko, durante a d?cada de 1970, a tese defende a exist?ncia de ?apenas dois valores-de-verdade?. Tal afirma??o diz respeito ? concep??o de multi-valora??o perpetrada pelo l?gico Jan ?ukasiewicz. Considerado um dos criadores das l?gicas multi-valoradas, ?ukasiewicz acrescentou, em adi??o aos valores fregeanos tradicionais de Verdade e Falsidade, um terceiro valor: o Indeterminado. Para ele, seu terceiro valor poderia ser visto como um passo al?m da dicotomia Aristot?lica entre o ser e o n?o-ser. De acordo com Suszko, as ideias de ?ukasiewicz sobre multi-valora??o se baseavam em uma confus?o entre valores alg?bricos (aquilo que ? descrito/denotado por senten?as) e valores l?gicos (verdade e falsidade). Assim, o terceiro valor-de-verdade criado por ?ukasiewicz seria apenas um valor alg?brico, isto ?, uma poss?vel denota??o para uma senten?a, mas n?o um valor l?gico genu?no. A tese de Suszko encontra respaldo em um resultado formal conhecido hoje como Redu??o de Suszko, um teorema que afirma que toda l?gica tarskiana pode ser caracterizada por uma sem?ntica bivalente. Esta disserta??o pretende ser uma investiga??o da tese de Suszko e de suas implica??es. A primeira parte ? dedicada ?s ra?zes hist?ricas da multi-valora??o e introduz as principais motiva??es de Suszko ao formular a distin??o entre valores alg?bricos e valores l?gicos, e assim revelar o car?ter duplo dos valores-de-verdade. A segunda parte explora a Redu??o de Suszko e apresenta seus principais desenvolvimentos; as propriedades das sem?nticas bivalentes em compara??o ?s sem?nticas multi-valoradas tamb?m s?o exploradas e discutidas. Por fim, a terceira parte investiga o conceito de valores l?gicos dentro do contexto de no??es n?o-tarskianas de consequ?ncia l?gica; o significado da tese de Suszko dentro desses ambientes tamb?m ? discutido. Mais ainda, os fundamentos filos?ficos das no??es de consequ?ncias n?o-tarskianas s?o discutidos ? luz do debate recente sobre pluralismo l?gico. / Suszko?s Thesis is a philosophical claim regarding the nature of many-valuedness. It was formulated by the Polish logician Roman Suszko during the middle 70s and states the existence of ?only but two truth values?. The thesis is a reaction against the notion of many-valuedness conceived by Jan ?ukasiewicz. Reputed as one of the modern founders of many-valued logics, ?ukasiewicz considered a third undetermined value in addition to the traditional Fregean values of Truth and Falsehood. For ?ukasiewicz, his third value could be seen as a step beyond the Aristotelian dichotomy of Being and non-Being. According to Suszko, ?ukasiewicz?s ideas rested on a confusion between algebraic values (what sentences describe/denote) and logical values (truth and falsity). Thus, ?ukasiewicz?s third undetermined value is no more than an algebraic value, a possible denotation for a sentence, but not a genuine logical value. Suszko?s Thesis is endorsed by a formal result baptized as Suszko?s Reduction, a theorem that states every Tarskian logic may be characterized by a two-valued semantics. The present study is intended as a thorough investigation of Suszko?s thesis and its implications. The first part is devoted to the historical roots of many-valuedness and introduce Suszko?s main motivations in formulating the double character of truth-values by drawing the distinction in between algebraic and logical values. The second part explores Suszko?s Reduction and presents the developments achieved from it; the properties of two-valued semantics in comparison to many-valued semantics are also explored and discussed. Last but not least, the third part investigates the notion of logical values in the context of non-Tarskian notions of entailment; the meaning of Suszko?s thesis within such frameworks is also discussed. Moreover, the philosophical foundations for non-Tarskian notions of entailment are explored in the light of recent debates concerning logical pluralism.
