Perspectives of Parents of Children with Autism Spectrum Disorder on a Community-Based Parent Education Program

In 2012 a community-based agency that oversees Intensive Behaviour Intervention services for young children diagnosed with Autism Spectrum Disorder (ASD) began delivering newly developed curricula to parents of eligible children. The curricula’s intent was to inform parents about ASD and Applied Behaviour Analysis, to increase their awareness of available community resources, and assist them to be active and engaged in their child’s learning. This mixed-method study used a program-specific survey and focus groups to explore the perspectives parents had on their involvement in these education sessions. Through constant comparison analysis 4 major and 3 minor themes emerged. In general, parents acknowledged that this parent education program included relevant content and a favourable delivery format. The study summarized a number of well-articulated, practical suggestions parents provided. Implications for practice would be applicable to educators interested in providing quality group-based education to parents of young children with ASD.

Photothermal beam deflection for non-destructive evaluation of semiconductor thin films

Non-destructive testing (NDT) is the use of non-invasive techniques to determine the integrity of a material, component, or structure. Engineers and scientists use NDT in a variety of applications, including medical imaging, materials analysis, and process control.Photothermal beam deflection technique is one of the most promising NDT technologies. Tremendous R&D effort has been made for improving the efficiency and simplicity of this technique. It is a popular technique because it can probe surfaces irrespective of the size of the sample and its surroundings. This technique has been used to characterize several semiconductor materials, because of its non-destructive and non-contact evaluation strategy. Its application further extends to analysis of wide variety of materials. Instrumentation of a NDT technique is very crucial for any material analysis. Chapter two explores the various excitation sources, source modulation techniques, detection and signal processing schemes currently practised. The features of the experimental arrangement including the steps for alignment, automation, data acquisition and data analysis are explained giving due importance to details.Theoretical studies form the backbone of photothermal techniques. The outcome of a theoretical work is the foundation of an application.The reliability of the theoretical model developed and used is proven from the studies done on crystalline.The technique is applied for analysis of transport properties such as thermal diffusivity, mobility, surface recombination velocity and minority carrier life time of the material and thermal imaging of solar cell absorber layer materials like CuInS2, CuInSe2 and SnS thin films.analysis of In2S3 thin films, which are used as buffer layer material in solar cells. The various influences of film composition, chlorine and silver incorporation in this material is brought out from the measurement of transport properties and analysis of sub band gap levels.The application of photothermal deflection technique for characterization of solar cells is a relatively new area that requires considerable attention.The application of photothermal deflection technique for characterization of solar cells is a relatively new area that requires considerable attention. Chapter six thus elucidates the theoretical aspects of application of photothermal techniques for solar cell analysis. The experimental design and method for determination of solar cell efficiency, optimum load resistance and series resistance with results from the analysis of CuInS2/In2S3 based solar cell forms the skeleton of this chapter.

Estabilidade e eficácia clínica de formulações cosméticas hidratantes contendo Vitaminas C e E

A adição de diferentes substâncias activas em produtos cosméticos, por exemplo, vitaminas e seus derivados, tem sido bastante frequente. Desta forma, é fundamental avaliar a estabilidade e eficácia de formulações cosméticas que contêm estes ingredientes. O objectivo deste trabalho foi o de avaliar a estabilidade física e a eficácia clínica da hidratação formulações cosméticas com base em pantenol, e contendo tetraisopalmitato de ascorbilo e a-tocoferol. Por isso, as formulações foram desenvolvidas com pantenol (FA), pantenol e tetraisopalmitato de ascorbilo e a-tocoferol (FBC), que foi submetido à análise do comportamento reológico, caracterizando-as como estável. Em seguida, foram subjectivamente e objectivamente analisados ??quanto à eficácia clínica em 25 voluntários por avaliação sensorial e técnicas de bioengenharia cutânea, em termos de teor de água do estrato córneo, a perda de água transepidérmica (TEWL) e microrrelevo da pele, antes e depois de 3 horas de aplicação . As formulações estudadas apresentaram estabilidade aceitável de acordo com os aspectos físicos considerados. Nos estudos de eficácia clínica, ambas as formulações melhoraram significativamente a hidratação da pele e reduziram a TEWL, e também demonstraram uma melhoria no microrrelevo da pele, mas estes resultados não foram estatisticamente significativos. FBC recebeu notas superiores FApor análise sensorial, com melhoria significativa da suavidade da pele, além de ser preferido em intenção de compra.

The relationship between diffuse spectral reflectance of the soil and its cation exchange capacity is scale-dependent

Diffuse reflectance spectroscopy (DRS) is increasingly being used to predict numerous soil physical, chemical and biochemical properties. However, soil properties and processes vary at different scales and, as a result, relationships between soil properties often depend on scale. In this paper we report on how the relationship between one such property, cation exchange capacity (CEC), and the DRS of the soil depends on spatial scale. We show this by means of a nested analysis of covariance of soils sampled on a balanced nested design in a 16 km × 16 km area in eastern England. We used principal components analysis on the DRS to obtain a reduced number of variables while retaining key variation. The first principal component accounted for 99.8% of the total variance, the second for 0.14%. Nested analysis of the variation in the CEC and the two principal components showed that the substantial variance components are at the > 2000-m scale. This is probably the result of differences in soil composition due to parent material. We then developed a model to predict CEC from the DRS and used partial least squares (PLS) regression do to so. Leave-one-out cross-validation results suggested a reasonable predictive capability (R2 = 0.71 and RMSE = 0.048 molc kg− 1). However, the results from the independent validation were not as good, with R2 = 0.27, RMSE = 0.056 molc kg− 1 and an overall correlation of 0.52. This would indicate that DRS may not be useful for predictions of CEC. When we applied the analysis of covariance between predicted and observed we found significant scale-dependent correlations at scales of 50 and 500 m (0.82 and 0.73 respectively). DRS measurements can therefore be useful to predict CEC if predictions are required, for example, at the field scale (50 m). This study illustrates that the relationship between DRS and soil properties is scale-dependent and that this scale dependency has important consequences for prediction of soil properties from DRS data

Time patterns in UK demand for alcohol and tobacco: an application of the EM algorithm

Capturing the pattern of structural change is a relevant task in applied demand analysis, as consumer preferences may vary significantly over time. Filtering and smoothing techniques have recently played an increasingly relevant role. A dynamic Almost Ideal Demand System with random walk parameters is estimated in order to detect modifications in consumer habits and preferences, as well as changes in the behavioural response to prices and income. Systemwise estimation, consistent with the underlying constraints from economic theory, is achieved through the EM algorithm. The proposed model is applied to UK aggregate consumption of alcohol and tobacco, using quarterly data from 1963 to 2003. Increased alcohol consumption is explained by a preference shift, addictive behaviour and a lower price elasticity. The dynamic and time-varying specification is consistent with the theoretical requirements imposed at each sample point. (c) 2005 Elsevier B.V. All rights reserved.

Enhancing change detection in low-quality surveillance footage using markov random fields

Urban surveillance footage can be of poor quality, partly due to the low quality of the camera and partly due to harsh lighting and heavily reflective scenes. For some computer surveillance tasks very simple change detection is adequate, but sometimes a more detailed change detection mask is desirable, eg, for accurately tracking identity when faced with multiple interacting individuals and in pose-based behaviour recognition. We present a novel technique for enhancing a low-quality change detection into a better segmentation using an image combing estimator in an MRF based model.

Historical Consciousness and Historical Media : A History Didactical Approach to Educational Media

This paper presents a theoretical approach to analysing educational media using the concept of historical consciousness. The concept of historical consciousness is defined and operationalised and its relevance for analysis of historical media discussed. One aspect of the theoretical framework proposed is then applied in an analysis of a history textbook account. The analysis finds that while the framework may be applied in analysis of textbooks, its results regarding historical consciousness are tentative and in need of further investigation from the perspective of how its users perceive and appropriate the textbook account. Still, it is argued that the framework proposed may be useful since it specifies how a historical consciousness may be manifested and what methodological approaches that can be used when analysing it.

Historical Consciousness, Historical Media, and History Education

This thesis by publication contains an introductory summary chapter and three papers. The first paper presents a study of how the concept of historical consciousness has been defined, applied, and justified in Swedish history didactical research. It finds that there is consensus regarding the definition of what a historical consciousness is, but that there is variation in how the concept is applied. It is suggested that this variation makes historical con­sciousness a complex and vague concept.      The second paper uses the results presented in the first paper as a point of departure and from thence argues for a broadened understanding of the concept of historical consciousness that incorporates its definition, applica­tion, development, and significance. The study includes research about his­torical consciousness primarily from Sweden, the UK, the USA and Canada. The paper presents a typology of historical consciousness and argues that level of contextualisation is what distinguishes different types of historical consciousnesses and that an ability to contextualise is also what makes his­torical consciousness an important concept for identity constitution and morality.      The third paper proposes a methodological framework of historical con­sciousness based on the theory of historical consciosusness presented in the second paper. It presents arguments for why the framework of historical consciousness proposed can be useful for the analysis of historical media and it discusses how aspects of the framework can be applied in analysis. It then presents a textbook analysis that has been performed according to the stipulated framework and discusses its results regarding how textbooks can be used to analyse historical consciousness and its development.

"Comida di buteco" : o botequim, um pedaço da alma carioca, em uma iniciativa de construção de comunidade virtual de marca

O botequim é um estabelecimento que serve comida caseira, em porções generosas e a baixo custo, também servindo petiscos típicos e bebidas, isto num ambiente informal, com arquitetura e decoração típicas. Durante muito tempo teve sua imagem associada ao ócio e ao vício, ao ponto dos proprietários rejeitarem a associação dos seus estabelecimentos ao termo botequim. Esta visão mudou com a recente valorização do termo botequim, através do lançamento de guias como o “Rio Botequim”, “Guia Veja Comer & Beber”, das colunas “Pé-limpo” e “Pé-sujo”, ambas publicadas no caderno “Rio Show” do jornal O Globo, e do concurso “Comida di Buteco”. Apesar de haver em todo território brasileiro 297.000 estabelecimentos semelhantes que ocupam em torno de 1.600.000, não são facilmente encontrados estudos que abordem o botequim de um ponto de vista empresarial. Objeto deste estudo o concurso “Comida di Buteco” foi criado em 2000 e atualmente acontece em 16 cidades de 8 estados brasileiros e conta com mais de 370 estabelecimentos concorrentes. O presente estudo tem por objetivo apresentar de que maneira os organizadores do concurso incentivam através de sua página no Facebook a formação de uma comunidade virtual de marca em torno do concurso e se esta se estende aos botequins participantes. Para a realização deste objetivo esta pesquisa se apoia em um referencial teórico mapeado dentro da literatura disponível sobre: o botequim; o concurso “Comida di Buteco”; marca e a criação de seus significados; comunidade de marca e comunidade virtual de marca. Optou-se por abordar o fenômeno de forma qualitativa usando-se a etnografia como metodologia para a coleta de dados e no tratamento destes aplicou-se a análise de discurso mediado por computador. O resultado da análise é confrontado com o referencial teórico e conclui-se que a organização do concurso “Comida di Buteco” incentiva a formação de uma comunidade virtual de marca em torno do concurso, através da troca de informações e opiniões, da divulgação do concurso e estabelecimentos, do incentivo a autoconsciência de grupo. Não foi possível comprovar se esta comunidade se estende aos estabelecimentos concorrentes, porém verificou-se que estes tiram proveito da divulgação de suas marcas pelo concurso.

Análise de agrupamentos dos dados de DFA oriundos de perfis elétricos de indução de poços de petróleo

The main objective of this study is to apply recently developed methods of physical-statistic to time series analysis, particularly in electrical induction s profiles of oil wells data, to study the petrophysical similarity of those wells in a spatial distribution. For this, we used the DFA method in order to know if we can or not use this technique to characterize spatially the fields. After obtain the DFA values for all wells, we applied clustering analysis. To do these tests we used the non-hierarchical method called K-means. Usually based on the Euclidean distance, the K-means consists in dividing the elements of a data matrix N in k groups, so that the similarities among elements belonging to different groups are the smallest possible. In order to test if a dataset generated by the K-means method or randomly generated datasets form spatial patterns, we created the parameter Ω (index of neighborhood). High values of Ω reveals more aggregated data and low values of Ω show scattered data or data without spatial correlation. Thus we concluded that data from the DFA of 54 wells are grouped and can be used to characterize spatial fields. Applying contour level technique we confirm the results obtained by the K-means, confirming that DFA is effective to perform spatial analysis

Efeitos do manejo comportamental de incontinência fecal em adolescente

A incontinência fecal, também conhecida como encoprese, é um transtorno de evacuação que acarreta prejuízos ao desenvolvimento psicossocial e orgânico da criança e do adolescente, e que demanda atenção e cuidado de pais e profissionais de saúde. No amplo contexto de tratamento da encoprese, a psicoterapia constitui importante recurso, sendo a terapia comportamental apontada como uma das modalidades mais promissoras e eficazes para o tratamento dessa dificuldade de eliminação. Este artigo apresenta o estudo dos efeitos do manejo comportamental de quadro de incontinência fecal em um adolescente de 14 anos, atendido em clínica-escola de Psicologia do interior do Estado de São Paulo durante 14 meses. A partir do referencial teórico da análise do comportamento, foi desenvolvido, em contexto psicoterápico, um conjunto de estratégias comportamentais com o cliente, bem como orientações aos pais, visando à gradativa extinção encoprética. No decorrer desse processo, o cliente apresentou significativas aquisições comportamentais de uso regular do banheiro e adequado controle esfincteriano, monitoradas semanalmente, que possibilitaram a plena extinção das ocorrências de sujidade, sendo avaliado o efeito em follow-up realizado três meses após o encerramento dessa intervenção.
