The present study compares applications of continuous multidimensional item response theory (MIRT) models for their diagnostic potential. Typically, MIRT models have not been used for diagnosing the possession of skills or attributes by students, but several researchers have suggested that they can potentially be used for this purpose (e.g., Stout, 2007; Wainer, Vevea, Camacho, Reeve, Rosa, Nelson, Swygert, & Thissen, 2001). This study applies MIRT models to a standardized eighth grade mathematics achievement test that was constructed based on a hierarchically-structured blueprint consisting of standards, benchmarks, and indicators. Only the highest level, consisting of four standards, was used to define the dimensions. The confirmatory models were defined using the standards that had been scored for involvement in each item. For the current study, the exploratory MIRT (EMIRT) model was interpreted with respect to the dimensions. Then, the compensatory and confirmatory MIRT (CMIRT) models and the full information bifactor model were fitted. The interpretation of dimensions, empirical reliabilities of person estimates, and test- and item-fit were examined. Also, dimension and pattern probabilities were obtained for determining their diagnostic potential. Last, a noncompensatory MIRT model (MLTM-D; Embretson & Yang, 2011) and the DINA model (Haertel, 1989; Junker & Sijtsma, 2001) in use as diagnostic models were analyzed to compare pattern probabilities with the compensatory CMIRT model.

Title: Incidence of injuries at top badminton players depending on physiotherapy and compensatory programmes Objectives: The main aim of this study is to find out what are the most frequent injuries at top badminton players taking part in the Czech extra league and in the first league in the season 2017/2018. Besides, the aim is also to find out if physiotherapy and compensatory programmes influence the decrease of the incidence of these injuries. And then, if badminton players devote thein time to compensatory programmes and use the possibilities of physiotherapy. Methods: For finding out the most frequent injuries at top badminton players we used a non-standardised questionnaire. The research had the character of a correlative - predilective study which studied the relationship between the incidence of injuries in badminton depending on physiotherapy and compensatory programmes. Results: The most frequent injuries among the Czech badminton players occur in the area of an ankle (47%), knee (34%) and shoulder joint (22%). According to the results, physiotherapy and compensatory programs proved a positive effect on reducing the incidence of injury. 25% of players working with a physiotherapist since childhood have never suffered injury. 68% of players who started to cooperate with a physiotherapist...

Title: Compensatory exercise as a complement to the training schedule for children of younger school age in figure skating Objectives: The main objective of this work is to identify the most frequently occurring muscular dysbalance in the studied group of younger school-age figure skaters. Therefore, in order to find out the fundamental deficiencies, we used simple tests and based on the deficiencies, we created a buffer of compensatory exercises. We will verify the results using the same tests as at the beginning of the initial measurement after the three-month preparatory period. Methods: In my work I used a functional muscular test to assess the flexibility and examination of a physiotherapist with the help of the MFK system. We do not only measure the muscular strength of the main muscle in individual tests, but we also investigate and analyze the performance of the whole movement. Testing was attended by five figure skaters in the younger school age. Results: Initial testing took place at the start of the preparatory period. A 3-month compensation program was then applied and after the test, the probands were again tested to determine the effect. The results of this work are described in the tables. The result of this work is that the most problematic parts were the abdominal, back muscles and...

However, it is worth asking: what is the role of low-income families s children within the public shcool? After all, when they are inserted into the educational system, mostly they show great difficulty to move along, thus creating a major problem for the school, since children who can not suceed in the first years of elementary school end up dragging this failure throughout their school life. For these children, educational assistance programs were created. But in what extent do they help and where they end up stigmatizing students who participate in those initiatives? In attempting to answer this questions, this study make the analysis of some educational assistance programs who proposed changes in the educational reality, offering more opportunities of progress for low-income children. The research is willing to establish whether they actually complied with its purpose or ultimately stigmatize students who participate in these projects. / A maior parte das famílias de baixa renda atribui à escola a solução para os seus problemas sociais, vendo no aparelho escolar a única chance de ascensão social. Contudo, cabe aqui perguntar: Qual é o espaço das crianças pobres dentro da escola publica? Afinal, quando inseridas dentro do sistema educacional, em sua maioria demonstram grande dificuldade para avançar, criando assim um grande problema para instituição escolar, uma vez que crianças que não conseguem obter sucesso nos primeiros anos do ensino fundamental acabam arrastando esse fracasso ao longo de toda sua vida escolar. Para essas crianças, foram criados os programas de auxilio pedagógico. Mas até que ponto eles ajudam e onde acabam por estigmatizar os alunos que deles participam? Na tentativa de responder essa pergunta, este trabalho buscou fazer a análise de alguns projetos de auxilio pedagógico que propuseram a mudança da realidade educacional, dando mais oportunidades de avanços às crianças de baixa renda. A pesquisa procura saber se eles realmente cumpriram com a sua finalidade ou acabaram por estigmatizar os alunos que participaram destes projetos de auxilio pedagógico.

Se manipulado de forma eficiente, o crescimento compensatório pode ser uma alternativa para reduzir o custo com a alimentação. No presente trabalho objetivou-se analisar o efeito bioeconômico do crescimento compensatório sobre sistemas intensivos de recria e terminação de bovinos de corte. Por meio de simulação, em um Sistema de Apoio a Decisão, a produtividade (Pr) e a resposta econômica foram avaliadas em quatro sistemas. Caracterizados por diferentes períodos de restrição alimentar (sem restrição, CONT; 90 dias de restrição, COMP90; 120 dias de restrição, COMP120 e 150 dias de restrição, COMP150) no período pós-desmama. Além disso, foram realizadas análises de risco e de sensibilidade, por meio de simulação de Monte Carlo. Os sistemas com regime alimentar restrito necessitaram de maior período de engorda (14, 21 e 35 dias para COMP90, COMP120 e COMP150, respectivamente) que CONT. O sistema COMP90 teve Pr (434,2 kg/ha/ano) similar ao CONT (434,0 kg/ha/ano) e ambos maiores que COMP120 (395,0 kg/ha/ano) e COMP150 (394,0 kg/ha/ano). A margem bruta/ha foi de 608,98; 493,5; 366,96 e 304,23 R$/ha/ano para os sistemas COMP90, CONT, COMP120 e COMP150, respectivamente. Entretanto, na análise de risco o sistema menos estável economicamente foi o CONT e o com menor risco foi COMP90. A análise de sensibilidade demonstrou que as variáveis com maior efeito sobre a margem bruta foram o preço do boi gordo, do bezerro e do milho usado no confinamento. O uso do crescimento compensatório pode ser uma ferramenta para redução de custos com a alimentação em sistemas de recria e engorda de bovinos de corte, mas a sua eficácia é influenciada pelo período de restrição. / When used efficiently the compensatory growth can be an option to reduce feeding cost. The aim was to analyze the bioeconomic effect of compensatory growth on intensive growing and fattening beef cattle systems. By simulation using a Decision Support System the productivity and the economic return were evaluated in four different systems, characterized by different periods of feeding restriction (no restriction, CONT; 90 days restriction, COMP90; 120 days restriction, COMP120 and 150 days restriction, COMP150). Besides, the risk analysis and sensitivity analysis were performed using Monte Carlo simulation. The systems with restriction of feeding required longer fattening periods (14, 21 e 35 days for COMP90, COMP120 e COMP150 respectively) than the CONT system. The COM90 obtained higher productivity (434,2 kg/ha/year) close of CONT system (434kg/ ha/ year) and both were higher than COMP120 (395 kg/ha/year) and COMP150 (394 kg/ha/year). The highest gross margin/ha was obtained in COMP90 (608,98 R$/ha/year) that was more than CONT (493,5 R$/ha/year), COMP120 (366,96 R$/ha/year) and COMP150 (304,23 R$/ha/ year). However, the risk analysis resulted in a highest risk using CONT system and lowest risk with COMP90. The sensitivity analysis demonstrated that the variables with the most effect on gross margin are beef, calf and corn prices. The use of compensatory growth can be a tool to reduce feeding costs in beef cattle systems however its effectiveness is influenced by the restriction period.

Problems resulting from the growth of this flow we mention floods , climate change , interference in the hydrological cycle and water balance . This problem , with the passage of time has been improving sustainable urban drainage analyzing the control flow that has to be done at source infiltration , percolation and storage . The importance of this work is to know the compensatory techniques so that they can be applied in the UFSCAR campus - São Carlos - SP . This study aimed to design, build , monitor and model a plan of infiltration, built in real scale, for stormwater management of the building with an area of 3001.3 m². The funds came from Project MCT / FINEP / Action Cross Environmental and Housing 07 /2009 Drainage - MAPLU2 - . Stormwater Management Urban 2 The soil characterization was performed considering their fitness levels , grain size, permeability, degree of compaction and profile this soil. The lifting of water infiltration into the soil testing was conducted with double ring . There was an technical compensatory plan infiltration met the six physical aspects , three urban and infrastructure aspects , environmental aspects and two health and two socioeconomic aspects . The method adopted for the design was the envelope -curve , using a return period of 10 years. Through electronic equipment and measurements of precipitation 32 actual rainfall events were monitored . In this period there were no leakage of the infiltration plan representing these events , an efficiency of 100 % in reducing runoff volume. The modeling technique was using the method of PULS . This model however was considered difficult to apply this technique , that due to uncertainties regarding the areas of infiltration by high initial infiltration capacity of the soil and the fact that the water has preferred areas in infiltration plan. / A intensa urbanização gerada a partir do século XX e o surgimento dos grandes centros urbanos ocasionou uma considerável mudança no uso e ocupação do solo; este passou a ser muito impermeabilizado resultando um aumento do escoamento superficial. Entre os problemas decorrentes do crescimento desse escoamento podemos citar as inundações, alterações climáticas, interferência no ciclo hidrológico e balanço hídrico. Desta problemática, com o decorrer do tempo foi-se aprimorando a drenagem urbana sustentável analisando que o controle desse escoamento tem que ser feito na fonte com infiltração, percolação e armazenamento. A importância deste trabalho é de conhecer as técnicas compensatórias para que estas possam ser aplicadas no campus da UFSCar - São Carlos - SP. Objetivou-se projetar, construir, monitorar e modelar um plano de infiltração, construído em escala real, para manejo de águas pluviais do prédio com área de 3.001,3 m². Os recursos vieram do Projeto MCT/FINEP/Ação Transversal Saneamento Ambiental e Habitação 07/2009 MAPLU2 Manejo de Águas Pluviais Urbanas 2. A caracterização do solo foi realizada considerando-se seus índices físicos, granulometria, permeabilidade, grau de compactação e perfil desse solo. O levantamento da infiltração da água no solo realizouse com ensaios de duplo anel. Verificou-se se técnica compensatória plano de infiltração atendia aos seis aspectos físicos, três aspectos urbanísticos e de infraestrutura, dois aspectos sanitários e ambientais e dois aspectos socioeconômicos. O método adotado para o dimensionamento foi o da curva-envelope, utilizando um período de retorno de 10 anos. Através de equipamentos eletrônicos e de medidas das precipitações foram monitorados 32 eventos de chuvas reais. Neste período não ocorreu nenhum extravasamento do plano de infiltração representando, nesses eventos, uma eficiência de 100% na redução do volume escoado. A modelagem da técnica foi utilizando-se o método de PULS. Esse modelo entretanto foi considerado difícil de ser aplicado nesta técnica, isto devido as incertezas em relação as áreas de infiltração pela alta capacidade de infiltração inicial do solo e ao fato da água ter áreas preferenciais no plano de infiltração.
