As particularidades na forma o de sujeitos na história sócio-espacial brasileira: algumas considera es sobre o Movimento Negro
Andrelino Campos
Geografares , 2011,
Abstract: O objetivo deste ensaio é compreender, no contexto dos movimentos sociais urbanos, a a o do movimento negro como um dos sujeitos responsáveis pela transforma o da história sócio-espacial brasileira. Entendemos que os movimentos sociais necessariamente s o reconhecidos pela sua universalidade como forma de identificar a a o societária entre tantas outras maneiras do agir dos grupos sociais. Contudo, a a o deles precisa ser identificada com o movimento do/no espa o/tempo (história/lugar) para que saibamos quais os objetivos que pretendem alcan ar no contexto de dada sociedade. Neste sentido, apesar da existência de inúmeros movimentos sociais urbanos negros pelo mundo a fora, algumas destas a es só podem ser encontradas no Brasil, caracterizando uma particularidade entre os movimentos sociais brasileiros e seus congêneres que poder o ser identificados na universalidade dos movimentos sociais urbanos. Ressalta-se ainda que, por meio da no o da pessoa-para-si e da pessoa-para-o-outro, far o parte da análise para que possamos compreender a articula o das diferentes escalas sócio-espaciais s o fundamentais a forma o do sujeito sociais, pois s o parte do movimento empreendido por toda e qualquer sociedade.

A DISTRIBUI O DOS OBJETOS GEOGRáFICOS E AS SUAS REPRESENTA ES ESPACIAIS
Andrelino de Oliveira Campos
Revista Tamoios , 2005,
Abstract: A Geografia, enquanto ciência, vive dentro de eternos conflitos internalizados no seu fazer. Pensando nesta perspectiva, entendemos que todos têm a responsabilidade de buscar novas saídas. Entretanto, estas novas saídas estejam nas concep es que n o foram bem compreendidas no ensino e nas pesquisas geográficas. é com este sentido, que apoiado, sobretudo na obra de Milton Santos, que retomamos os estudos dentro do campo da metodologia geográfica como uma das possibilidades de leitura do real. Neste sentido, entender a produ o do espa o geográfico a partir da acep o concreto-abstrato de Santos, tendo analisando quatro categorias e conceitos que s o indissociáveis: processo, estrutura, fun o e a forma. Contribuindo para o entendimento do movimento que o espa o e o tempo constroem a existência dos objetos geográficos. Palavras-chave: Metodologia da Geografia; processo; estrutura; fun o; forma.

Abstract: the main objective of this study was to evaluate the estimates generated by a diametric distribution model, under the biologic point of view. another objective was to evaluate the efficiency of the percentage of entries method to determine the technical age for the first and second thinning in eucalypt stands. the qualitative evaluation of the model was carried out through the evaluation of the results obtained by the percentage of entries method, the behavior of the diametric distributions projected for the future, and the behavior of the remaining distributions after some thinning simulations, theoretically, logically and biologically speaking. according to the results it was concluded that the diametric distribution model proposed is biologically correct and consistent. growth stagnation is stimulated after thinning. it also was concluded that the percentage of entries method is suitable to determine the technical age for the first and second thinning. the model evaluated allows the simulation of various situations, generating consistent estimates and it can be used without restrictions, that is, situations can be simulated with or without the conditions observed in the field.

Abstract: the objective of the present study was to evaluate the applicability of the clutter model in thinned eucalypt stands. the study was developed with data from the copener florestal, bahia pulp enterprise, located in the municipality of alagoinhas, bahia, brazil. data came from a thinning experiment established in eucalypt stands using a randomized block design with four treatments and three repetitions, each one in a different place, totaling 48 plots with a mean area of 2,600 m2 each. the plots were measured at 27, 40, 50, 58, 61 and 76 months of age, and the thinning was carried out at 58 months. for model adjustment, a system of simultaneous equations was used with stand information such as basal area, volume, age and site index. from the model adjustment, a yield table with variable density was built, and the technical cutting age was determined for various thinning intensities. simulations were carried out with the yield table. it was concluded that the clutter model was efficient to predict the present and future yields of the thinned eucalypt stands, showing its usefulness in the analysis of alternative managements, such as the technical cutting age determination for various site indexes and thinning intensities.

Abstract: data used for this study are from a thinning essay established in stands of eucalypt carried out in the copener florestal enterprise, in the northeast region of bahia state, brazil. data were collected in 48 rectangular permanent plots, with an area of 2,600 m2. the first thinning was made at 58 months. various percentages of basal area reductions were used. the objective of the study was to build and quantitatively evaluate, through statistical tests, a growth and yield model by diameter class for thinned eucalypt stands. the theoretic redistribution of diameters by class was made through equations that include both linear and non-linear relations between the weibull function parameters in a future age (b2 and g2) and the parameters at the present age (b1 and g1) and with some stand characteristics at the present and future age. three equations systems were analyzed. the equations were analyzed through the adjusted determination coefficient, the correlation coefficient and the graphical analyses of the residues. tests were performed to verify the compatibility of the systems and the identity among them. the selected system is compatible and assures the property that when the future age (i2) is equal to the present age (i1), the diametric distribution at the future age is equal to the diametric distribution at the present age. this system generated accurate and consistent estimates of growth and yield per diameter class.

Abstract: the objective of this work was to specify a growth and yield model in that volumetric yield is a function of the basal area per hectare and mean height of the eucalyptus plantations. thus, data of permanent plots located in the state of bahia-brazil were used, with ages ranging from 28 to 89 months. after analysis, it was verified that the proposed model provided more precise volumetric estimates than the clutter model (1963) for young plantations, independently of the productivity class. however, the proposed model provided less precise volumetric estimates in the technical cut age (itc) for smaller and larger productivity classes.

Abstract: the objective of this work was to determine the most profitable management method, among the variation of age and thinning intensities, site index, interest rates, wood prices and last cutting age. to achieve this goal, data of a thinning experiment established at empresa copener florestal ltda, bahia, were used. the prediction system used was developed by clutter (1963). the economic evaluation method used was the equivalent periodic benefit (bpe). the results showed that the method with thinning was economically better than the method without thinning, but as the thinning intensity increased the bpe values tended to decrease. also, lower interest rates and higher site indexes were observed to increase the method profits. the method that provided the greatest profit was obtained with thinning at four and last cut at nine years of age. the variables site index, interest rate and establishment cost did not significantly influence the determination of the most profitable method, that is, the most profitable method remained the thinning at four and last cut at nine years of age. on the other hand, the variable thinned wood price influenced the determination of the most profitable method. the increase in price according to the harvesting age resulted in thinning at six and last cut at nine years of age as the most profitable method. similarly, the increase in wood price of the last cut according to the cutting age resulted in thinning at four and last cut at 12 years of age as the most profitable method. the simulation of increasing the price of thinned and last cut wood, at the same time, generated as the most profitable method thinning at six and last cut at 12 years of age. it was concluded that there was a direct influence of variables prices of thinned and last cut wood on the determination of the most profitable method.
Higher Education in the United States and Brazil: How the Two Systems Origins Shaped Their Further Development  [PDF]

Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.518184
Abstract: This article draws a parallel between higher education in the United States and Brazil placing emphasis on its different origins. The college tradition in the United States began with Harvard in the seventeenth century soon after the pioneers settled in the new land. These institutions were private, closer to their Board of Trustees than to the British Crown, and had a deeply religious character. Since one of their objectives was to train religious leaders, character formation was very valued. Located far from city centers, colleges used to operate as almost a total institution. The first Brazilian higher education institutions were created in the early nineteenth century when the Portuguese Royal family left Lisbon for its colony, Brazil. Schools of Medicine, Law, Pharmacy, etc. were called Faculdades. Highly elitist they were located in large cities. They followed the model of Napoleonic Great French Schools, which were secular institutions aimed at training professionals. United States and Brazil have quite different higher education systems, but both still sustain, to a large extent, their respective marks of origin and pay tribute to them.
El deber de mejorar: Higiene e identidad obrera en el socialismo madrile?o, 1884-1904
Campos,Ricardo;
Dynamis , 2011, DOI: 10.4321/S0211-95362011000200012
Abstract: se pretende analizar la modulación y transformaciones de los discursos y reivindicaciones socialistas en materia sanitaria durante el periodo comprendido entre 1883 y 1904, con el objeto de demostrar su alto grado de politización y su deseo de integración social y política. en este sentido, se analiza el papel político desempe?ado por la salud y la higiene en la construcción de una identidad obrera, así como la tensión y las ambigüedades ideológicas generadas por la necesidad de apropiarse de un discurso ajeno, emitido desde la ciencia, pero necesario para conseguir plantear reivindicaciones que perseguían la inclusión social de los obreros como ciudadanos de pleno derecho y su dignificación.
