Geoquímica de elementos maiores e traços de granitoides neoproterozoicos da província Borborema e sua correlação com propriedades físicas de rochas

This paper discusses the correlation of thermal conductivity, density and magnetic susceptibility with composition of major and trace elements of Neoproterozoic igneous bodies from Borborema Province, Northeastern Brazil. These properties were used as potential markers among the studied magmatic suites. For the correlation between petrophysical and geochemical properties it was considered a set of 195 chemical analyzes of granitoid rocks, separated by the degree of acidity in basic, intermediate and acidic. Major (SiO2, Al2O3, Fe2O3, MgO, CaO, Na2O, K2O and TiO2) and some trace elements (Rb, Sr, Ba, Zr, Th and U) that are usually linked to the formation of the most common minerals of igneous rocks were used. The results show that SiO2 has the best positive correlation with the thermal conductivity, while Al2O3, CaO, Fe2O3, MgO and TiO2 exhibit negative correlation for the same property. The correlation with density is opposite to that one for these oxides with the thermal conductivity. The magnetic susceptibility did not correlate with the elements studied. The results for thermal conductivity and density indicate a tendency of SiO2 and oxides with higher affinity with mafic minerals (Al2O3, CaO, Fe2O3, TiO2 and MgO) in controlling these petrophysical parameters. The set of samples was divided into five different magmatic suites based on their lithogeochemical aspects into: i) peralkaline / alkaline; ii) alkaline; iii) calc-alkaline; iv) high potassium calcium alkaline; and v) shoshonitic. Data analysis showed that the thermal conductivity and density presented good results in the individualization of these suites, notably between peralkaline / alkaline, alkaline suites, calc-alkaline and shoshonitic. However, the high-K calc-alkaline suite overlapped with the other. In contrast, the magnetic susceptibility did not show effective results for separating the five chemical suites.

Análise de microestrutura e de características geotécnicas de misturas de resíduo de polimento de porcelanato e solo

Brazil is a country in development, rich in natural resources. In order to grow sustainably, it is necessary to Brazil to preserve its environment, which is an expressive challenge, especially to industries, such as those producing ceramic materials. This study was developed using Porcelain Tile Polishing Residue (RPP) in blends with soil to build compacted fills. This residue is a slurry generated during the polishing process of porcelain tiles and contains powdery material from the polished tile, the abrasives used during the process and cooling water. The RPP was collected from a private company located in Conde/PB and it was mixed with a sandy-clayey soil, to build the fills. Laboratorial tests were conducted with pure soil, pure RPP and blends in proportions of 5%, 10%, 15% and 20% of RPP in addition to the dry mass of pure soil. The Chemical and Physical Characterization tests performed were: specific solid weight, grain size distribution, laser analysis of grain size distribution, Atterberg limits, X ray fluorescence, X ray diffraction, scanning electron microscopy and soil compaction,. The materials and blends were also compacted and direct shear tests and plate load tests were performed. Plate load tests were conducted using a circular plate with 30 cm diameter, on specimens of pure soil and 5% blend, compacted in a metallic box inside the Soil Mechanics Laboratory of the Federal University of Rio Grande do Norte, Brazil. Both mechanical tests performed were conducted under inundated conditions, willing to reduce the influence of soil suction. An evaluation of the results of the tests performed shows that RPP is a fine material, with grain size distribution smaller than 0,015mm, composed mainly of silica and alumina, and particles in angular shape. The soil was characterized as a clayey sand, geologically known as a lateritic soil, with high percentages of alumina and iron oxide, and particles with rounded shape. Both the Soil and the blends presented low plasticity, while the residue showed a medium plasticity. Direct shear tests showed that the addition of RPP did not cause major changes into blends’ friction angle data, however, it was possible to note that, for the proportions studied, that is a tendency of obtain lower shear stresses for higher percentages of RPP in the blends. Both pure soil and 5% mixture showed a punching disruption for the Plate load test. For this same test, the allowable stress for 5% mixture was 44% higher than the pure soil, and smaller vertical settlement results for all stresses.

Reserva extrativista Acaú-Goiana: tragédia comum ou decisão coletiva?

In recent years we have observed, in Brazil, the expansion of democratic spaces, providing the use of participatory management strategies in common-pool areas. However, the existence of a co-management model does not guarantee its practice, neither that it will prevent the depletion of common features characterizing the tragedy proposed by Hardin. In this work we analysed the management of Acaú-Goiana RESEX which is located in the cities of Acaú (PB) and Goiana (PE), eight years after its legal creation. We evaluated how much the users of RESEX possess information (even if non formalized) regarding the common use of area and whether they exhibit collectivist values. We used as an interpretative tool the facilitators principles of common resource management (PGRC) identified by Elinor Ostrom and the questionnaire of human values proposed by Schwartz. The human values questionnaire was applied to 240 individuals, half beneficiary and the other half non-beneficiary, only the beneficiaries were submitted to the questionnaire of PGRC. Interviews were conducted in the period of May to September 2014. We tested three hypotheses: 1) The degree of dependence from RESEX resources will play an important role on indirect knowledge of the PGRC; 2) the inclusion of individuals in a communal area (RESEX) increases collectivists values; 3) higher collectivist value rates increases knowledge of PGRC. To this end, we defined levels of socio-economic dependence of RESEX resources, knowledge of PGRC and individual values. GLM statistic analysis of mean comparison and correlation were employed. Our results showed that the knowledge on six of the seven items analyzed in the basic principles (PGRC) is still low. The extended land area and the high number of users may be exerting a detrimental effect on the development of a co-management. Contrary to expected, it was not the dependency who influenced knowledge on the PGRC, but the time spent in contact with the RESEX. This indicates that direct contact with the environment, not the dependence of it, that raises awareness about PGRC. According to our hypothesis, individuals with collectivist values showed greater knowledge of PGRC and reduced hours of work within the RESEX, indicating a greater tendency of individuals refrain their use of the common resource. Individualistic values correlated with less knowledge of a PGRC. Among the beneficiaries, individuals with higher individualistic values had higher monthly income, while among non-beneficiaries there was no such correlation, demonstrating the economic advantages of individualism (free-riding) in situations of non-private use of resources. Our data emphasize the importance of guiding the main actors in the development of a co-participatory management in the direction of the basic principles, and to develop collectivist values among users of a common good can raise awareness of these principles.

Formação profissional do cuidador de idosos em instituições de longa permanência

The old caretaker's work seeks to minimize suffering and morbidity resulting from physical, cognitive and emotional limitations of these individuals, being a practice permeated by the uniqueness of the subjects involved, therefore, a process in constant construction. In this notion, the caregiver's role is crucial to assist the elderly in everyday life, aiming at improving their quality of life. This study has descriptive and analytical character with quantitative and qualitative approach aimed to investigate the professional training of active caregivers in long-term stay institutions for the Elderly (ILPIs) in Natal/RN in the year 2014. For this, semi-structured interviews were conducted with 63 caregivers employed in nine ILPIs, representing 75% of the professionals performing activities in these institutions. The interviews captured data on the socioeconomic profile, the perception about the profession and training of caregivers. Data were analyzed by observation of absolute and relative measures of central tendency of the numeric variables frequencies. It was found that most caregivers had poor socioeconomic status and had no specific training course to practice caregiver role. However, among those who carried out courses, most reported that the content covered during the training gave security to perform the practice, although they have shown a contradiction when referred to the need to build capacity. The perception of care is mainly related to love and care for the other while the choice of profession is associated with care practice itself. The results also indicate the presence of a low level of formal training for the exercise of the occupation, also revealing the weaknesses ranging from the absence of a core curriculum that can guide the formation, compounded by the low educational professionals in focus.

(Table 2) Metazoan meiofauna abundance in sediments obtained during POLARSTERN cruise ANT-XIX/3 (ANDEEP-1)

Meiofauna standing stocks and community structure are reported for the first time for abyssal soft-sediment samples in Antarctic waters. At seven stations within a depth range of 2274-5194 m a total of 128 sediment cores were retrieved with a multiple corer (MUC) on board of the R.V. Polarstern during the ANDEEP-1 cruise (ANT XIX/3). The metazoan meiofauna (defined by a lower size limit of 40 µm) was identified and counted, and one core per station was preserved for CPE, C/N, TOM and grain size analyses. Meiofauna densities are in the range of 2731 Ind./10 cm² at 2290 m depth and 75 Ind./10 cm² at 3597 m depth, with nematodes being the dominant group at all stations. Nematodes account for 84-94% followed by copepods with 2-8% of the total meiofauna. Other frequent taxa found at each station are kinorhynchs, loriciferans, tantulocarids, ostracods and tardigrades. There is a general tendency of decreasing abundances of metazoan meiofauna with increasing depth, but not all higher level taxa displayed this pattern. In addition, a tendency of decreasing higher taxon density with increasing depth was observed. Standing stocks are higher than the average found at similar depths in other oceans.

AS MARCAS E O CONSUMIDOR: Um estudo dos discursos da publicidade na perspectiva da modificação dos estereótipos na representação da família.The

Os papeis de homens e mulheres na sociedade contemporânea têm sido reestruturados, assim como a própria noção das estruturas familiares se renova. Algumas marcas estão atentas a essas mudanças e, no contexto mercadológico, fica evidente que os consumidores são diversos, com novas demandas e expectativas pelo reconhecimento dessa diversidade. Esta dissertação discute a mudança de abordagem na representação da família, demonstrando suas mutações de papeis na publicidade, esta vista como um produto sociocultural. Para tanto foi desenvolvida uma pesquisa qualitativa subsidiada pela análise de discurso de linha francesa. Primeiramente, o estudo qualitativo se desenvolve a partir de uma abordagem bibliográfica e documental e uma parte empírica de análise de discurso de campanhas publicitárias dos últimos anos, selecionadas a partir de seu foco nas representações familiares contemporâneas, de marcas que as tratem com naturalidade e demonstrem aceitar essas transições, buscando-as através da análise de casos múltiplos de amostras intencionais os avanços quando se trata dos modelos familiares, elementos que se desviam de representação conservadora da família. Demonstrou-se que há uma tendência de algumas marcas reforçarem qual é o público que desejam atingir através de suas construções discursivas que apontam para o reconhecimento das famílias reconstituídas, para a adoção e para a homo e monoparentalidade, ou seja, para a confirmação da existência dos variados tipos de família.

Pedagogía y política. La campaña de alfabetización CREAR en la historia reciente de la educación de adultos en la Argentina de los '70

La tesis que presentamos es el resultado de un trabajo de investigación sobre la campaña de alfabetización CREAR realizada entre 1973 y 1975. La Campaña de Reactivación de la Educación del Adulto para la Reconstrucción, estuvo dirigida por la Dirección Nacional de Educación de Adultos (DINEA) en la etapa de la recuperación democrática luego de dieciocho años de gobiernos autoritarios combinados con la proscripción de la fuerza política mayoritaria. Apoyada en el registro testimonial de quienes fueron sus inspiradores, conductores, coordinadores, alfabetizadores, la investigación se propone analizar la articulación entre pedagogía y política durante la realización de la campaña. Los testimonios rescatados en la presente investigación, representan figuras destacadas de la campaña de alfabetización en su doble dimensión de pedagogos y militantes políticos. En esta dirección, la presente tesis se propone recuperar los principales debates y discusiones que se generaron en torno a su desarrollo a partir de quienes fueron sus testigos. ¿Qué sueños proyectaban en la alfabetización? ¿Qué formas de imbricación entre lo político y lo pedagógico se produjo en su desarrollo? ¿Cómo se plasmó dicha articulación? ¿Sobre qué ejes vertebraron su discurso? Entre la pedagogía de la liberación y la doctrina del peronismo ¿qué lectura predominó? El desarrollo de este trabajo de investigación se propone invitar a recorrer este camino cargado de tensiones y contradicciones que, esperamos, se convierta en una contribución al campo de la historia de la educación reciente de la Argentina

Son objeto de estudio sus antecedentes académicos, sus relaciones políticas, así como las iniciativas y reformas realizadas al sistema de salud local. Esta intensa actividad contribuiría de gran modo a su designación como candidato a vicegobernador, para las elecciones de 1951, en representación del peronismo jujeño.

HIJOS La Plata. Memorias tensionadas. Análisis de los relatos sobre el pasado reciente que elaboran los militantes de HIJOS

El presente trabajo propone mostrar y analizar cómo los integrantes de la agrupación HIJOS La Plata (organismos de derechos humanos conformado por hijos de víctimas del terrorismo de Estado argentino) han construido sus memorias acerca del pasado reciente. Interesan, más específicamente, las maneras en que elaboran relatos referidos al terror estatal llevado a cabo por la última dictadura (1976-1983) y al período de radicalización política inmediatamente anterior. Mientras la memoria humanitaria, propia del los organismos de derechos humanos que nacieron como respuesta defensista frente al terror estatal, centra sus denuncias en el carácter humano de las personas cuyos derechos fueron violados y omite o silencia sus trayectorias políticas; la memoria militante de los HIJOS rescata en clave reivindicatoria las experiencias políticas de sus padres y pretende no recordarlos sólo como víctimas, sino también como luchadores políticos. El objetivo de este trabajo es indagar las tensiones que resultan de la pertenencia de HIJOS al movimiento de derechos humanos, muchas de cuyas prácticas reproducen, y los conflictos que supone su intención de reivindicar la lucha revolucionaria de sus padres

La comunidad del filicidio : La vida de Dominguito de Domingo Sarmiento y su transposición fílmica

El artículo propone una lectura comparativa de La vida de Dominguito, de Domingo Sarmiento, y su transposición cinematográfica de 1944, titulada Su mejor alumno y escrita por Homero Manzi y Ulyses Petit de Murat. Para ello, se exploran las continuidades y desplazamientos en las imágenes de Sarmiento y Dominguito que ambas obras postulan. Primero, se aborda la película en tanto escenificación del pasaje de una imagen de Sarmiento que va del proyecto de la educación popular a la cultura pop. Luego, se introduce la idea de que en las dos obras la imagen del hijo funciona como el sustento de una comunidad política basada en el ideal ético de la philia. Sin embargo, el lugar fallado de ese modelo comunitario está determinado por el acto del filicidio, que a través de la metáfora del pueblo-niño que no puede superar su propia infancia, habilita una lectura de la película en relación con el contexto sociohistórico de emergencia de la imagen pop de Sarmiento en el momento de gestación del peronismo.

La basileía "revolucionaria" de Nabis

El rey Nabis de Esparta es caracterizado por las fuentes literarias antiguas como un tirano al haber emprendido una serie de reformas radicales que, particularmente en sus contenidos sociales, atentaban contra el orden establecido y ponían en peligro la supremacía en el Peloponeso de una conservadora liga aquea sostenida en las clases propietarias y respaldada por las imparables legiones romanas. Es el propósito del presente artículo analizar las bases de esa monarquía "revolucionaria" de Nabis, así como el alcance, los objetivos y la fortuna final de sus medidas, que supusieron un intento de acomodarse a la realidad de los estados helenísticos sin renunciar por ello a las señas de identidad y al acervo cultural espartano. La finalidad última era reconquistar parte de su pasado esplendor militar y lograr un lugar digno, si no hegemónico, en el complejo e inestable tablero geopolítico peloponésico, pero la elite aquea no cesó hasta acallar toda reivindicación socioeconómica en la sociedad lacedemonia.

Peronismo, dictadura y universidades privadas en la Argentina de los años 70

A partir del análisis de normativas universitarias, bibliografía especializada y fundamentalmente fuentes documentales y testimoniales, este artículo aborda la trama del sector universitario privado durante el complejo interregno que significaron los años setentas para la historia reciente Argentina. Observaremos que tras el reingreso del peronismo al poder del Estado en 1973, la alta sustentabilidad adquirida por el sector en años anteriores fue puesta en jaque: conflictos estudiantiles, intervenciones políticas y un crecimiento institucional refrenado, fueron algunos de sus rasgos distintivos. En cuanto a la última dictadura militar (1976-1983), abrió una contradictoria etapa de desarrollo para las universidades privadas. Pese a la alternancia de católicos conservadores en el área educativa y al sesgo privatista identificado como un hito del modelo económico implementado, el sector privado resultó contraído en el marco del avasallamiento más brutal del sistema universitario en su conjunto. Sin embargo, algunas universidades católicas resultaron beneficiadas con importantes estímulos económicos.
