The Saline Valley Conservancy District (SVCD) formed in 1980 to provide a stable source of water to many communities in Southern Illinois. The SVCD well field located in the thickest, most productive region of the Saline Valley Aquifer lies directly adjacent to a reclaimed coal mine. Subsurface movement and surface discharge from the mine has been shown to be responsible for deterioration of water quality in the surrounding area, including the aquifer. Previous studies conducted in the region have addressed water supply issues and simulated contaminant transport from the reclaimed mine. The limited scope of these models did not extend to natural hydrogeological boundaries. This study extended the model boundaries to natural boundaries including the Saline River to the south, the Wabash and Ohio Rivers to the east, and the bedrock high pinch-out and fining valley textures to the west. The flow model uses parameters from each study as a base then calibrated to 18 discrete head measurements. Initial contaminant transport runs using values from previous studies show successful mine reclamation except for surface discharge to a nearby ditch from well pumping. An analysis was performed that varied parameters to determine if any likely scenarios may cause the plume to travel farther than anticipated. These scenarios include things such as cessation of surface discharge, increasing contaminant source load, and altering recharge and hydraulic conductivity. In all cases sulfate concentrations in the SVCD production wells modeled up to 155mg/L which is under the EPA drinking water guideline for sulfate. Three wells in particular, SVCD-1, SVCD-4, and SVCD-7 never model higher than 7mg/L indicating that several wells lie outside the influence of the sulfate plume. Based on the results of the scenario analysis, the mine can shut off remediation pumping without overly contaminating the SVCD water supply.

O acesso ao desempenho em áreas específicas da linguagem, lexical, fonológica e morfológica, prover subsídios teóricos e empíricos que auxiliarão a desenvolver uma clara compreensão da linguagem oral e possíveis alterações. Sendo esta uma área de maior carência no desenvolvimento da psicologia, no Brasil, com claros reflexos negativos nas investigações e no exercício profissional, faz sentido que um maior número de acadêmicos se dedique a este tema desenvolvendo instrumentos de medidas confiáveis. Tais instrumentos auxiliarão no diagnóstico de distúrbios da comunicação verbal e posterior intervenção. Participaram deste estudo 203 crianças provenientes da Região Metropolitana do Recife, de ambos os sexos, entre 5 e 7 anos, contatadas através de escola particular, escolas públicas, creche, da Clínica Escola da Universidade Federal de Pernambuco, e comunidades de baixa renda. Estas crianças foram distribuídas da seguinte forma: 118 pertencentes à rede pública, 65 pertencentes à rede privada e 20 sem acesso a escolarização. Relevante mencionar que faz parte da amostra um grupo de 31 crianças, da rede pública e privada, com queixas de alteração de linguagem. Os dados foram coletados em três etapas. Na primeira etapa foi utilizado o Teste de Matrizes Progressivas Coloridas de Raven, e provas de consciência fonológica (categorização de sons e subtração de fonemas). Na segunda etapa foi realizado um teste de vocabulário receptivo o Test de Vocabulario en Imagenes Peabody (TVIP) e prova analogia de sentenças. Já a terceira etapa foi realizada, seis meses após a segunda etapa, com 37% da amostra total. Nesta etapa as crianças foram retestadas na prova de vocabulário receptivo a fim de analisarmos a precisão dos resultados. A fim de obter uma amostra de crianças com queixas de alteração de linguagem foi necessário realizar um questionário ou entrevista aos pais, com o objetivo de coletar dados relevantes sobre possíveis transtornos da linguagem. O processo de análise iniciouse por um delineamento das qualidades psicométricas da prova de vocabulário receptivo. Para a análise da validade dos resultados no teste, procedemos a uma serie de analises tanto de tipo paramétricos (correlações, regressões múltiplas e anovas) como não-paramétricos (SSA) visando estabelecer a relação entre o TVIP e as demais provas lingüísticas e cognitivas usadas neste nosso estudo. Observamos que as tarefas de analogia de sentenças e subtração de fonemas apresentam uma relação positiva e significativamente mais alta com o TVIP, e os resultados parecem sugerir uma maior contribuição destas tarefas para o aumento do vocabulário. Foi observado também que (a) as crianças com queixa de alteração apresentaram resultado inferior nas provas lingüísticas e que esses resultados do TVIP sugerem uma contribuição deste instrumento de avaliação para futuros diagnósticos de distúrbios da comunicação; (b) o conjunto de variáveis cognitivas e de linguagem se diferencia segundo a origem social e variáveis do desenvolvimento da criança. Enfim estes resultados são discutidos visando não somente melhor entender a aquisição e desenvolvimento do vocabulário, bem como a sua integração com outras dimensões da linguagem, como também subsidiar uma discussão psicológica acerca da necessidade da elaboração de instrumentos de medida que atendam ao rigor científico e com a qualidade necessária para subsidiar as decisões clínicas e ou acadêmicas na área de psicologia e fonoaudiologia

In 1968, a 54,000 acre coal mine commenced operations on Black Mesa, Arizona, an arid and semi-arid region inhabited by the Hopi Tribe and Dine Nation. The coal mine fuels the power plant that generates electricity for the Central Arizona Project, which pumps renewable Colorado River water to Phoenix and Tucson. Water for mine-operations is pumped from a non-renewable groundwater aquifer upon which the Hopi and Dine depend. After forty years of development, conflict characterizes industrial groundwater exploitation on Black Mesa; there continues to be little understanding of the relationship between industrial withdrawals and its impacts upon hydrological and social-ecological systems of the region.Large-scale natural resource development is predicated upon deterministic studies required to disclose all potentially adverse impacts. This study performs a postaudit of groundwater model predictions used to determine the significance of these impacts. It demonstrates that drawdown caused by the mine was underestimated; drawdown caused by communities was overestimated; the models failed to capture the linear relationship between water level decline and spring discharge; and water levels predicted to recover by 2007 continue to decline in 2010.The Regulatory Authority developed four criteria for determining if damage to the aquifer had occurred in response to mining; over time, two damage thresholds were crossed and two had never been evaluated. A new model was implemented for regulatory purposes; simulations showed that a distant spring 60 miles from the mine is unaffected by the mine's withdrawals. The postaudit demonstrates how declining discharge from this spring has a strong relationship with industrial withdrawals (r = -0.84; R2 = 0.71; p < 0.0001); local pumping and precipitation have no statistically significant relationship with discharge from this spring.In 2008, the Regulatory Authority revised the four threshold criteria; all negative trends were removed from regulatory purview (including spring discharge) and remaining criteria assumed insurmountable damage thresholds; their condition will be determined by model simulations rather than actual observations.The Black Mesa case study reinforces the argument that the legislatively required process for predetermining environmental impacts is an elaborate ritual in which a manifestly political decision is disguised as unbiased scientific fact.

The Peabody Picture Vocabulary Test (PPVT) is a widely used receptive vocabulary screening tool, but it is not without its limitations, such as inadvisable I.Q. usage and a standardization procedure that lacks scope. A revision of the PPVT, known as the Peabody Picture Vocabulary Test-Revised (PPVT-R) was published in 1981, and contains a more complete standardization procedure as well as some structural changes of the test itself (Dunn, 1981). Speech/language pathology, whose diagnosticians most commonly use the age equivalent value, is a profession that would gain from information which deals with the equivalency of the PPVT-R to the original PPVT. The purpose of the study was to compare age equivalent values obtained from the PPVT and the PPVT-R for a preschool aged population. Specifically, this study sought to discover whether or not significant differences existed between the age equivalent values derived from the PPVT and the PPVT-R. Eighty children, age three years, six months to four years, six months participated as subjects in the study, selected on the basis of their chronological age and enrollment in one of ten selected preschools. The subjects were divided into four groups (N=20), and each group was administered one form of the PPVT (A or B) and one form of the PPVT-R ( L or M). The resultant groupings were: I (A and L); II (A and M); III ( B and L); and IV ( B and M).

The purpose of the present study was to further investigate the effects of motivation on the intellectual attainment of Negro children. In view of previous research and realizing the importance of related study on inventive and achievement, the following hypothesis was proposed: Inducement of motivation between pre-and post-administrations of Form A of the Peabody Picture Vocabulary Test would result in significantly greater magnitude of change in scores for the experimental group of Negro children than for the control group.

Este trabalho teve dois objetivos : verificar se a emissão de Tatos face a figuras variava segundo a dimensão cor, e estudar o vocabulário do pré-escolar.Para tal, trabalhou-se com 48 sujeitos, de quatro,cinco e seis anos. Em cada faixa etária havia dois sub-grupos, igualmente constituídos, quanto ao sexo e número de sujeitos, sendo a única diferença a ordem de apresentação do material colorido e preto-branco. o material consistiu de dois tipos de figuras: pranchas do PLDK -nível P (três séries), apresentadas coloridas e preto-branco e uma gravura. As crianças foram testadas individualmente em duas sessões. Os resultados indicam que: no PLDK nível P - a) de modo geral, não houve diferença de desempenho face as pranchas preto-branco e coloridas; b) houve várias correlações significantes entre cada série e o total, embora poucas inter-séries; c)quanto a seqüência de apresentação, apenas o grupo de quatro nos revelou ganho na seqüência preto-branco considerando a variável idade, de forma geral os mais novos tiveram desempenho inferior ao dos mais velhos. Na gravura: apenas o grupo de seis anos diferiu dos outros qrupos, não havendo diferença entre os sexos. Na comparação PLDK nível P e gravura, não foi encontrada nenhuma correlação significante. Tendo em vista a extensão da amostra, bem como a pouca informação científica sobre o desempenho no PLDK nível P, especialmente no Brasil, foi sugerida a realização de outras pesquisas. / The purposes of the present study were to investigate the influence of the dimension co1our in the emission of Tacts, face to pictures, and the vocabulary of preschool children. A group of forty-eight children of four, five, and six years old were the subjects during the research. In each age group the subjects were usually divided into two groups, the only difference being the order of presentation of coloured or black-white picture cards. The results in the PLDK indicate that : a)there were no significant differences in the performance , as a whole , face to colored or black-white cards ;. b) there were various significant correlations between achievement in each serie and the whole performance o The inter-series correlations however , were weak; c) further to the sequence of presentation , the results indicate that only the four years old group revealed better performance when the coloured set was presented showing the black-white one; d) regarding the sex variable, only once there was a difference between boys and girls e)considering the age variable, the younger children achieved a lower score than the older ones. The results collected after the presentation of the printed picture showed that the six years old group presented higher score when compared to the younger groups. The latter ones presented no differences among themselves. Considerering the variable sex, no difference was found. The scores particularly achieved by the presentation of the cards and printed picture were also compared and no significant correlation was found. Taking into consideration of the sample and lack of scientific information about performance in the PLDK Level P, mainly in Brazil, further research on the subject is suggested.
