Psicomotricidad y deficiencia mental : contribución a su estudio mediante los test de L. Bender y A. Rey.

Comprobar si los test miden los mismos factores. Comprobar si existe correlación entre los resultados obtenidos por la aplicación del B. G y del Rey y los CI de los respectivos individuos. Comprobar si se puede obtener un diagnóstico fiable de la deficiencia mental. 30 niños con edades comprendidas entre 9 y 13 años comprendidos en 'deficientes ligeros y borderlines'. Los CI fueron obtenidos mediante la aplicación de una bateria de test compuesta por: Ballard, TEI, García Yagüe, Ampe Factorial y Ampe Elemental, Raven y en algunos casos, el Terman. Test de Copia de una figura compleja de A. Rey y Test Gestáltico Visomotor de L. Bender y el Copia de una figura compleja de A. Rey miden los mismos factores, ya que la correlación no es lo suficientemente alta como para poder afirmar que miden los mismos factores y sólo los mismos factores. Existe correlación entre el test Guestáltico Visomotor de L. Bender y los CI de los sujetos, ya que el resultado nos indica una correlación moderada y que la relación entre ambas variables es considerable. No ocurre así con el test de Copia de una figura compleja de A. Rey y los respectivos CI de los sujetos, ya que el resultado de la correlación y una casi insignificante relación entre ambas variables. Tanto el test Guestáltico Visomotor de Bender, como el de Copia de una figura compleja de Rey, no nos sirven para un diagnóstico fiable de la deficiencia mental, si bien el B.G puede servirnos aunque no sea muy fiable, según deducimos del resultado de la correlación.

Evaluación de la integración de alumnos con discapacidad en la educación básica.

Evaluar la estrategia de Taller Educativo de Integración (TEI) de alumnos con discapacidad en la educación básica.. Participan en el estudio 6 escuelas incorporadas al TEI por más de 4 años. La muestra está integrada por 6 directores de dichas escuelas, 6 profesores de educación especial que atienden TEI, 50 profesores de Educación General Básica (EGB) que tienen cursos con alumnos de integración y 60 padres de alumnos de EGB de cursos con niños integrados.. Se parte de un marco conceptual en el que se definen las distintas variables consideradas. Los tests utilizados se elaboran exprofeso para el estudio. Las fuentes de variable que se operacionalizan son: aceptación del director, aceptación del profesor de EGB, aceptación del profesor TEI, funcionamiento técnico y funcionamiento administrativo. De dichas fuentes dependen a su vez muchas otras variables que son analizadas.. Los tests se construyen teniendo en cuenta las variables operacionalizadas; miden la aceptación y aplicación de criterios en aspectos cualitativos.. Se mide la confiabilidad a través del método de 'formas paralelas', administrando dos formas equivalentes a un mismo grupo. Se aplican de forma individual a los directores y grupal a los profesores de TEIs. La aplicación a padres y a alumnos la realizan profesores entrenados. Los estadígrafos que se utilizan en el análisis son la frecuencia absoluta y los porcentajes. Para verificar la asociación entre la aceptación y funcionamiento técnico y administrativo se aplica el coeficiente de contingencia.. La estrategia de TEI es aceptada por los diferentes agentes educativos. El niño con discapacidad es aceptado por los directores, profesores, padres y alumnos de las escuelas de EGB donde existen TEIs. . Se demuestra que los alumnos pertenecientes a la educación especial se integran complementariamente en cursos de EGB. Se pone de manifiesto que el profesor de curso común realiza acciones de integración y promueve sólo la socialización del niño con discapacidad, no comprometiéndose con los aprendizajes académicos de éste. La integración entre profesores de EGB y de Educación Especial no es efectiva a nivel técnico. Los directores de las escuelas no se involucran en los aspectos técnicos-curriculares. De todo ello se deduce que el Ministerio de Educación debería implementar la estrategia de integración a partir del nivel prebásico con continuidad en los niveles siguientes del sistema..

Early modern Oxford bindings in twenty-first century markup

Purpose – The Bodleian Binders Book contains nearly 150 pages of seventeenth century library records, revealing information about the binders used by the library and the thousands of bindings they produced. The purpose of this paper is to explore a pilot project to survey and record bindings information contained in the Binders Book. Design/methodology/approach – A sample size of seven pages (91 works, 65 identifiable bindings) to develop a methodology for surveying and recording bindings listed in the manuscript. To create a successful product that would be useful to bindings researchers, it addressed questions of bindings terminology and the role of the library in the knowledge creation process within the context that text encoding is changing the landscape of library functions. Text encoding formats were examined, and a basic TEI (Text Encoding Initiative) transcription was produced. This facilitates tagging of names and titles and the display of transcriptions with text images. Findings – Encoding was found not only to make the manuscript content more accessible, but to allow for the construction of new knowledge: characteristic Oxford binding traits were revealed and bindings were matched to binders. Plans for added functionality were formed. Originality/value – This research presents a “big picture” analysis of Oxford bindings as a result of text encoding and the foundation for qualitative and statistical analysis. It exemplifies the benefits of interdisciplinary methods – in this case from Digital Humanities – to enhance access to and interpretation of specialist materials and the library's provenance record.

An investigation to enhance understanding of the stimulation of weed seedling emergence by soil disturbance

Enhanced understanding of soil disturbance effects on weed seedling recruitment will help guide improved management approaches. Field experiments were conducted at 16 site-years at 10 research farms across Europe and North America to (i) quantify superficial soil disturbance (SSD) effects on Chenopodium album emergence and (ii) clarify adaptive emergence behaviour in frequently disturbed environments. Each site-year contained factorial combinations of two seed populations (local and common, with the common population studied at all site-years) and six SSD timings [0, 50, 100, 150, 200 day-degrees (d°C, base temperature 3°C) after first emergence from undisturbed soil]. Analytical units in this study were emergence flushes. Flush magnitudes (maximum weekly emergence per count flush) and flush frequencies (flushes year 1) were compared between disturbed and undisturbed seedbanks. One year after burial, SSD promoted seedling emergence relative to undisturbed seedbanks by increasing flush magnitude rather than increasing flush frequency. Two years after burial, SSD promoted emergence through increased flush magnitude and flush frequency. The promotional effects of SSD on emergence were strongest within 500 d°C following SSD; however, low levels of SSDinduced emergence were detected as late as 3000 d°C following SSD. Accordingly, stale seedbed practices that eliminate weed seedlings should occur within 500 d°C of disturbance, because few seedlings emerge after this time. However, implementation of stale seedbed practices will probably cause slight increases in weed population densities throughout the year. Compared with the common population, local populations exhibited reduced variance in total emergence measured within sites and across SSD treatments, suggesting that C. album adaptation to local pedo-climatic conditions involves increased consistency in SSD-induced emergence.

Mapeando caminhos de autoria e autonomia : a inserção das tecnologias educacionais informatizadas no trabalho de educadores que cooperam em comunidades de pesquisadores

Este trabalho se insere no ponto de interseção entre educação, trabalho e tecnologia. Parte da questão: a interação entre educadores pesquisadores na elaboração e desenvolvimento de seus projetos contribui para a constituição de comunidades de pesquisadores e para a construção de alternativas para a formação de educadores autores e autônomos no trabalho com as tecnologias educacionais informatizadas (TEI)? Tem como objetivo investigar a constituição e o desenvolvimento de comunidades de pesquisadores, identificando e analisando as contradições em movimento neste processo, a fim de contribuir para a construção de alternativas para a formação de educadores no trabalho com as TEI. Para isso, realizo uma experimentação na Faculdade de Educação da Universidade Federal do Rio Grande do Sul, no período de junho de 2003 a maio de 2004. No projeto, utilizo weblogs como ambientes de aprendizagem por entender que seu formato dinâmico, aberto e público seria um fator diferencial para a investigação. A investigação é de natureza qualitativa, caracterizada como pesquisa-ação crítica. Os resultados da pesquisa indicam que a interação em comunidades de pesquisadores contribui para um processo de formação de educadores autores e autônomos na construção e na utilização das TEI e possibilitam propor uma alternativa para a formação de educadores. Uma rota possível que passa por trazer as TEI para a formação e para o trabalho dos professores por meio dos seus projetos e fazendo esta inserção de forma consciente e crítica.

Primeiro registro de teiidae (squamata, lacertilia) para o pleistoceno superior do estado do Rio Grande do Sul, Brasil

Este trabalho trata do primeiro Squamata (Lacertilia, Teiidae) do Pleistoceno superior do Estado do Rio Grande do Sul, Brasil, e atribuído ao gênero Tupinambis. O material (MCN-PV 2184) é uma hemimandíbula direita, basicrânio, três vértebras dorsais, rádio e ulna esquerdos de um mesmo indivíduo, e provém da Formação Touro Passo, cujos répteis eram antes representados apenas por Testudines. O espécime apresenta as sinapomorfias dos Teiidae e muitas características das espécies recentes de Tupinambis, mas dintingue-se pelo maior tamanho e pelos seguintes caracteres: tubérculo basal mais horizontalizado, dentário e esplenial muito altos, coronóide relativamente baixo, articular com margem ventral marcadamente côncava, e crista adutora muito proeminente, pelo que a face lateral do articular está voltada látero-ventralmente.

Estrutura da população de Coleodactylus natalensis Freire, 1999 (Squamata: Sphaerodactylidae) no Parque Estadual Dunas de Natal, Rio Grande do Norte, Brasil

Coleodactylus natalensis Freire, 1999, an endemic species of Atlantic Forest fragments around the Natal municipality, Rio Grande do Norte State, Brazil, has as type locality the Parque Estadual Dunas de Natal (05º48 S to 05º53 S and 35º09 W to 35º12 W), one of the largest restinga (herb and shrub association on sand dunes along the Brazilian coastline) associate fragment, surrounded by urban zone, placed on setentrional Atlantic Forest limits. We made estimates on populational density, spatial distribution, habitat and microhabitat preferences and feeding ecological aspects like sazonal and sexual variations on diet, prey electivities and niche breadth. We randomly sampled ninety-six 50m2 quadrants in each of the four habitats identified in the study area. Were collected 49 specimens and their stomach contents were analyzed; prey items found were correlated with leaf-litter invertebrates from habitat samples. We found a 98,5 ± 75,5 individuals/ha density, in grouped distribution pattern on densest habitats and random distribution on others habitats. This species lives mostly on leaf-litter in forest habitats, in higher humidity points, with lower temperatures, deeper leaf litter and lower sea level elevations than the randomly chosen points in the study area. Isopoda and Aranae were the most important prey categories in numeric, frequency and volumetric terms. Niche breadth has an intermediate value and was variable in sexual and in habitat terms. There was no correlation between morfometric measures and prey size on diet. The C. natalensis population studied seems to be diet opportunist, although selects larger prey items. The Parque Estadual das Dunas do Natal has several indications of anthropic pressure from the surrounding urban area that may affects the local C. natalensis population. Thus, the fragility of this species calls for urgent conservation efforts

Cardiac function in dogs with chronic Chagas cardiomyopathy undergoing autologous stem cell transplantation into the coronary arteries

This study assessed the effects of a single intracoronary injection of autologous stem cells on the cardiac function of dogs with Chagas cardiomyopathy. Bone-marrow-derived stem cells were delivered into the right and left coronary arteries of 5 mature dogs with mildly compromised cardiac function due to chronic Chagas cardiomyopathy. Blood pressure and electrocardiographic and echocardiographic parameters were recorded at monthly intervals for 6 mo in the 3 dogs that survived. Although no changes were observed in the electrocardiogram and blood pressure, there was a significant increase in peak velocity of aortic flow 3 mo after stem cell transplantation. Pre-ejection period, isovolumic relaxation time, and the Tei index of myocardial performance were reduced significantly 4 mo after the procedure. All significant changes persisted to the end of the study. The results suggest that the transplantation of autologous bone-marrow-derived stem cells into the coronary arteries of dogs with Chagas cardiomyopathy may have a beneficial effect but the small number of dogs studied was a limitation.

Ecologia alimentar e comportamento de forrageamento de Ameivula aff. ocellifera (Squamata: Teiidae) em área de caatinga do nordeste do Brasil

This study investigated the influence of intrinsic and extrinsic factors on the feeding ecology and foraging behavior of the whiptail lizard Ameivula aff. ocellifera, a new species widely distributed in the Brazilian Caatinga, and that is in process of description. In attendance to the objectives, the Dissertation was structured in two chapters, which correspond to scientific articles, one already published and the other to be submitted for publication. In Chapter 1 were analyzed the general diet composition, the relationship between lizard size and prey size, and the occurrence of sexual and ontogenetic differences in the diet. Chapter 2 contemplates a seasonal analysis of diet composition during two rainy seasons interspersed with a dry season, and the quantitative analysis of foraging behavior during two distinct periods. The diet composition was determined through stomach analysis of lizards (N = 111) collected monthly by active search, between September 2008 and August 2010, in the Estação Ecológica do Seridó (ESEC Seridó), state of Rio Grande do Norte. Foraging behavior was investigated during a rainy and a dry month of 2012 also in ESEC Seridó, by determining percent of time moving (PTM), number of movements per minute (MPM) and prey capture rate by the lizards (N = 28) during foraging. The main prey category in the diet of Ameivula aff. ocellifera was Insect larvae, followed by Orthoptera, Coleoptera and Araneae. Termites (Isoptera) were important only in numeric terms, having negligible volumetric contribution (<2%) and low frequency of occurrence, an uncommon feature among whiptail lizards. Males and females did not differ neither in diet composition nor in foraging behavior. Adults and juveniles ingested similar prey types, but differed in prey size. Maximum and minimum prey sizes were positively correlated with lizard body size, suggesting that in this population individuals experience an ontogenetic change in diet, eating larger prey items while growing, and at the same time excluding smaller ones. The diet showed significant seasonal differences; during the two rainy seasons (2009 and 2010), the predominant prey in diet were Insect larvae, Coleoptera and Orthoptera, while in the dry season the predominant prey were Insect larvae, Hemiptera, Araneae and Orthoptera. The degree of mobility of consumed prey during the rainy seasons was lower, mainly due to a greater consumption of larvae (highly sedentary prey) during these periods. Population niche breadth was higher in the dry season, confirming the theoretical prediction that when food is scarce, the diets tend to be more generalized. Considering the entire sample, Ameivula aff. ocellifera showed 61,0 ± 15,0% PTM, 2,03 ± 0,30 MPM, and captured 0,13 ± 0,14 per minute. Foraging mode was similar to that found for other whiptail lizards regarding PTM, but MPM was relatively superior. Seasonal differences were verified for PTM, which was significantly higher in the rainy season (66,4 ± 12,1) than in the dry season (51,5 ± 15,6). It is possible that this difference represents a behavioral adjustment in response to seasonal variation in the abundance and types of prey available in the environment in each season

Participação social e designação de espécie-bandeira: ações complementares à conservação de um parque estadual em área urbana

Facing environmental problems the planet appears several alternative preventive and control on behalf of the equation between development and environmental protection. One of the alternatives implemented in Brazil to conservation of biodiversity was the creation of protected natural areas regulated by the National System of Conservation Units (SNUC). This is an integrated study of the Comunication / Environmental Conservation, which prioritizes social participation as a complementary in the conservation process, the particular case of the Dunas do Natal State Park, the first conservation area in Rio Grande do Norte, for full protection. It takes into account the roles environmental, scientific and Park, which harbors a unique biodiversity, including endemic species and the fact being located in an urban area. It proposes the use of two complementary instruments, such as strategies for conservation. Considering the various individual experiences, it was analyzed the perception that the community is directly related to the Park. From this promoted the democratization of information about the park, its biodiversity and conservation. As another conservation tool, it was suggested the use of a flagship species for the park, or a body chosen symbol for environmental or social reasons, in order to protect and conserve certain natural environments, from the understanding and co -community participation. In this case, as proposed flag Coleodactylus natalensis species, the lizard-the-litter, to be endemic remnants of Atlantic Forest Park as having the type locality, be one of the smallest species of the world, South America's lowest-dependent shadow of the forest, sensitive to human action and therefore very vulnerable. This suggestion finds support in the degree of public acceptance that interacts directly with the Park, as a result of the evaluation of their perceptions. It was further observed in this study that this symbology to be used in order to promote the democratization of the Park and its biodiversity has an identification result, curiosity and probable involvement of the population with the issues of the Park

Rendimentos de carcaça, dos cortes comerciais e da porção comestível de bubalinos Murrah castrados abatidos com diferentes períodos de confinamento

Avaliaram-se as características de carcaça de búfalos Murrah castrados terminados em confinamento. Foram utilizados 20 bubalinos Murrah (15 meses de idade e peso inicial de 207 kg), castrados e descornados, divididos em quatro grupos homogêneos e abatidos aos 75, 100, 125, 150 dias de confinamento, após período de adaptação. Ao abate, as carcaças foram identificadas, resfriadas por 24 horas para pesagem e cálculo dos rendimentos das meias-carcaças, dos cortes dianteiro, ponta-de-agulha, traseiro total e serrote. Não houve diferença estatística para o rendimento de carcaça. Os pesos de traseiro total, serrote e dianteiro apresentaram aumento linear, porém, observou-se efeito cúbico do período de confinamento sobre os rendimentos de traseiro total e dianteiro. Verificou-se ainda aumento linear dos pesos de filé-mignon, contrafilé, fraldinha, coxão mole, coxão duro, lagarto, sebo, porção comestível e ossos. O período de confinamento promoveu efeito linear decrescente sobre os rendimentos de patinho, músculo traseiro e maminha + alcatra e linear crescente para fraldinha e sebo.
