Over the past two decades, a large body of research has examined the issues of eating disorders as well as compensatory behaviors in collegiate competitive athletes. Up to 49.1% of student-athletes engage in disordered eating and compensatory behaviors, while up to 7.1% of athletes have symptoms that reach the threshold of formal psychiatric diagnoses. Greater symptoms are linked to reduced athletic and academic performance, both of which may impact physical and psychosocial functioning later in adulthood. However, most athletes suffer from these symptoms in isolation, as these behaviors are often undetected by athletic trainers and coaches. The purpose of the current study was: (a) to examine the prevalence of both formal eating disorders and disordered eating symptomatology in a sample of collegiate student-athletes; (b) to explore the frequency of compulsive exercise occurrence; (c) to investigate the differences in athletes’ disordered eating, compulsive exercise, and body image concerns by gender, sport type, and level of athletic participation; and (d) to assess the relationships among athletes’ disordered eating, compulsive exercise, and body image concerns, as well as associations between athletes’ age and each of these three variables. In total, 128 NCAA Division I varsity and club athletes completed the Eating Disorder Examination Questionnaire (EDE-Q), Compulsive Exercise Test (CET), and Multidimensional Body Self-Relations Questionnaire – Appearance Scales (MBSRQ-AS). Correlational analysis, Independent two-sample, and Welch’s t-tests were conducted to establish statistical significance for the relationships of interest. Out of 128 athletes, 11 athletes (8.6%) scored in the clinically significant range on at least one EDE-Q subscale. Four athletes (3.2%) met criteria for Bulimia Nervosa, 3 athletes (2.4%) met criteria for Binge Eating Disorder, and 2 athletes (1.6%) met criteria for Unspecified Feeding or Eating Disorder. In addition, 40 athletes (31.3%) reported subclinical symptoms of an eating disorder. Nineteen athletes (14.85%) scored above the clinical cut-off score for compulsive exercise behavior. Female athletes reported greater disordered eating symptomatology and body image dissatisfaction than males. In addition, lean-sport athletes had a higher prevalence of maladaptive eating behaviors than non-lean sport athletes. Age was not associated with athletes’ disordered eating, compulsive exercise, and body image scores. Also, no differences were found between club and varsity athletes for the same variables. Positive correlations were found between athletes’ eating pathology and their compulsive exercise behaviors, suggesting that greater eating disorder symptoms were associated with greater excessive exercise engagement. In contrast to athletes with no symptoms of an eating disorder, athletes with symptoms of an eating disorder reported using exercise as a weight control measure. Higher levels of body image dissatisfaction were also associated with greater eating pathology. This study addressed a number of methodological shortcomings across the body of eating disorder research (e.g., studies with insufficient sample sizes, lack of group comparisons by age and level of athletic participation, and suboptimal psychometric measures) and underscored the need for a new generation of studies. The study also explored the frequency of compulsive exercise, a compensatory behavior which is highly prevalent, but often overlooked among athletes. The study findings may aid coaches, athletic administration, and mental health professionals in identifying at-risk athletes. The study findings also inform the development of prevention and treatment efforts. / Kinesiology

Central Appalachian headwater streams in coalfield areas are prone to mining disturbances, and compensatory mitigation is required in cases of documented impacts. Stream construction on reclaimed mines is a common mitigation strategy. Streams constructed as compensatory mitigation are meant to restore structural and functional attributes of headwater streams and are often evaluated by measuring structural ecosystem characteristics. However, replacement of stream ecosystem functions is essential for mitigation of mining disturbances from an ecosystem perspective. This research compared selected structural and functional measures in eight constructed streams on mined areas to those of four forested reference streams across two years. Three organic matter functions were evaluated: riparian litterfall input, leaf breakdown, and periphyton accrual. Constructed streams were typically warmer than reference streams and also had elevated specific conductance, elevated oxidized nitrogen concentrations, depressed benthic macroinvertebrate richness, and lower levels of canopy cover. Functionally, litterfall input and total leaf breakdown means for constructed streams were approximately 25% and 60% of reference means, respectively. Leaf breakdown in constructed streams appeared to be inhibited as a result of reduced processing by benthic macroinvertebrates as well as inhibition of microbial and physicochemical pathways. Constructed streams with total breakdown rates most similar to reference-stream levels had the coldest stream temperatures. Areal periphyton biomass, benthic algal standing crop, and senescent autotrophic organic matter in constructed streams were roughly quadruple, double, and quintuple those of reference streams, respectively. Indicator ratios also suggested stream-type differences in periphyton structure. Mean algal accrual was greater in constructed streams than in reference streams during leaf-on seasons. My results suggest that light is likely the primary factor driving accrual rate differences during summer and fall, but that temperature may also be important during fall. Planting a diverse assemblage of native riparian trees and ensuring their successful development can inhibit benthic irradiance and thermal energy inputs while providing similar quantity and quality of OM to constructed streams, thereby fostering replacement of reference-like OM functions in some streams. / Ph.

Studies to date of Title I of the Elementary and Secondary Education Act have not yielded definitive evidence of increased student achievement or of the effects of instructional resource allocations on student reading achievement. This evidence has been obscured by methodological flaws, instrumentation problems, a continued focus on national rather than local-level evaluation, and the investigation of resource variables over which the local schools have little or no control. The degree of Title I impact on the student it is designed to serve is determined by decisions made at the local school and classroom levels. Previous investigations have found that most of the variation in student achievement lies within rather than between the local schools. For these reasons, this study identifies locally controlled and easily changed types of instructional resource allocations which are expected to influence the achievement of students in Title I instructional groups within the schools. Each resource allocation is defined by several variables which jointly represent the several aspects of each resource. The relationships between the levels of allocation of these resources and the levels of student achievement in Title I classes are investigated using a hierarchical multiple regression model. The effects of three sets of resource variables on the reading achievement of 4,332 second, third, and fourth-graders in fifteen Virginia public school systems are investigated by determining the incremental amounts of achievement variance which each type of resource allocation contributes to the total explained variance using classrooms as the unit of analysis. The results indicate that variations in the amounts of instructional time, the proportion of total teacher time spent in instruction, and the student-to-teacher ratio are not associated with significant achievement increments. In addition, the degree of administrative support of Title I instruction and the activities of parent advisory councils do not explain significant amounts of achievement. However, there is some evidence that the use of instructional aides in the classroom is related to increases in achievement. The findings of this study indicate that the effects of Title I instructional resource allocations may exist primarily within classrooms rather than between classrooms. Interactions between individual student characteristics and the ways in which instructional resources are allocated by the teacher in the classroom are suggested as a possible source of Title I effects. / Ph.

Title: Evaluation of actual state of children locomotor system for students of primary school. Objectives: Determine the current satus of locomotor system of children of primary school age by assessing a body posture of chosen sample of children and create compensation exercises for school and after-school physical education moments. Methods: We used the method of aspection in which we were watching deviations in body posture of different parts of body and their mutual position in sagittal and lateral view with using the test of Jaroš and Lomíček, Klein and Thomas. Results: We found out that within the chosen sample more than half participants have a correct body posture. Nevertheless, 48,5 % of participants have defective body posture. Weakening occurred primarily in the abdominal area and pelvis, in the back curve and when looking from behind a lot of participants have left to stand shoulder blades. Keywords: physical education moment, poor body posture, muscle imbalance, compensatory exercises.

The objective of this thesis is to examine the presence of the poor posture or the muscle imbalances at younger school-age children. Children do actively sports in a ski club for a long time; they also have a year training plan. Stationary functions and muscle activity in physiological position were investigated by physiotherapist who indicated some poor posture and muscle imbalances. On the basis of that examination there were recommended some compensatory exercises that can help to adjust or to eliminate detected imbalances. Recommended exercises became a part of the club training program, but the main part was practiced at home. According to the entrance and final examination of the participants we can assess the positive influence of the compensatory exercises to muscle imbalances and the children musculoskeletal system. Considering the results of the thesis we are able to proclaim that the long-term exercises can completely eliminate muscle imbalances. The contribution of this thesis has an irreplaceable importance for the work with children in the ski club.

Esta dissertação é resultado de uma pesquisa com atingidos pela Usina Hidrelétrica Serra do Facão no sudeste de Goiás. Foram coletadas histórias de vida de moradores da zona rural de Goiás em dois momentos distintos. O primeiro em 2009, antes da instalação da barragem do rio São Marcos. O segundo momento das entrevistas foi pós o deslocamento compulsório, em 2012 e 2013, com a usina em funcionamento. Este intervalo entre as entrevista nos permitiu analisar o que foi planejado e o que foi efetivamente vivido por estes moradores do sertão goiano. Este empreendimento desapropriou 420 famílias, moradoras da zona rural em seis municípios: Catalão, Ipameri, Cristalina, Davinópolis, Campo Alegre de Goiás, em Goiás e Paracatu, no triângulo mineiro, Minas Gerais. Tomamos como recorte analítico as famílias remanescentes ou as famílias retornadas a terra, sendo assim, selecionamos seis histórias de vida que nos evidenciaram o que foi este processo de expulsão de suas terras de origem e as formas de reconstruir suas vidas agora não mais margeadas pelo rio. Os colaboradores foram mulheres e homens de distintas idades, todos moradores das beiras do rio São Marcos, localizados na zona rural do município de Campo Alegre de Goiás, que teve a maior área atingida e a maior quantidade de famílias desapropriadas. Por meio da História Oral, registarmos histórias de vida nas quais foram expostos os mecanismos de sobrevivência destes afogados. Transcriadas, as histórias de vida revelaram a complexidade deste cenário e demonstram a face perversa de expulsão do camponês de suas terras. Estes sujeitos tem outros conhecimentos para além do português letrado, que os permitiram reconfigurar a vida já tão dura pela lida na terra e pelos desmandos do estado. Revelou também que é preciso superar práticas autoritárias e de subordinação política na relação entre mediadores da barragem e camponeses, como uma das condições para uma nova retomada em suas vidas. / This dissertation is the result of a research about people affected by Serra do Facão Hydroelectric Dam at south-east Goiás. The histories of people who lived in the rural area were collected at two distinct times. First before the dams construction at São Marcos River in 2009. The second moment of interviews was after the mandatory move, in 2012 and 2013, with the power plant already producing. This time offset allowed us to analyze what had been planned and what the former residents of this area actually experienced. This venture expropriated 420 families living in the rural areas of six cities: Catalão, Ipameri, Cristalina, Davinópolis and Campo Alegre de Goiás in Goiás and Paracatu in Triângulo Mineiro region of Minas Gerais. As analytical approach taken cover the reminiscent families or families which returned to their land, so we selected six life stories what was this process of expulsion from their own land and ways of rebuilding their lives, now, no longer at the border of the river. The interviewed people were women and men of different ages, all residents of São Marcos river borders, in rural areas of the city of Campo Alegre de Goiás, the one with the largest affected area and dispossessed families as well. Through Oral History, we recorded their life stories in which the mechanisms of survival of those drowned were exposed. Transcreated, These guys have other knowledge beyond the literate Portuguese, which allowed them to reconfigure life already so hard for the land labor and government excesses. Also revealed that it is necessary to overcome authoritarian and political subordination in the relationship between mediators of the dam and peasants practices as a condition for a new resume in their lives.

The nature of social risks covered up by the state welfare structure was considered during the characterization of the social security authority s duty to compensate the insured. The field of analysis was restricted to benefits that were rejected by public administration and afterwards reviewed by the judiciary, through the verification of the illegality of such acts, with the aim of providing the benefit to the insured in court. Compensatory damages are not characterized by the mere improper rejection of benefits, because they are not in re ipsa compensatory damages. On the other hand, it was criticized the understanding which exempts from responsibility the public entity, under the argument of regular exercise of law, when the administrative act is emanated from within a certain margin of interpretative reasonableness of the social security rule. Permeating the criteria and assumptions of civil liability by public administration, it was concluded that the duty to reimburse compensatory damages regarding social security requires the attendance of a normative cause. Grounded on that theory, considering that welfare activity decreases the risks to which the insured is exposed, the losses are only attributable to social security when its operations frustrate the legal expectations of the insured. To characterize this frustration, it is required that public administration misuses the interpretation/application of social security rules. In turn, the parameters of public administration s operation can be objectively evaluated considering the situation of the insured in view of their legal position within the social security system / No presente trabalho, a atenção está dirigida à compatibilização da estrutura da responsabilidade civil em situações de potencialidade lesiva à esfera moral do segurado da Previdência Social. Considerou-se a natureza dos riscos sociais encobertos pela estrutura previdenciária estatal, quando da constatação dos pressupostos de caracterização do dever de indenizar da autarquia previdenciária. Delimitou-se o campo de análise aos atos de concessão de benefícios indeferidos administrativamente que venham a ser revistos pelo Poder Judiciário, verificando a ilegalidade desses atos, com o fito de determinar o reconhecimento do segurado à prestação de benefício em sede judicial. Afastou-se a caracterização dos danos morais tão somente pela simples negativa indevida dos benefícios, por não se tratarem de danos morais in re ipsa. De outra parte, criticou-se a corrente jurisprudencial que exime de responsabilidade o ente público, sob a excludente da ilicitude caracterizada como exercício regular de direito, quando o ato administrativo é emanado dentro de certa margem de razoabilidade interpretativa da norma previdenciária. Perpassando pelos critérios e pressupostos de responsabilidade civil extracontratual da Administração Pública, concluiu-se que o dever de indenizar os danos morais no âmbito previdenciário exige a presença do liame normativo verificado pelo nexo de imputação. Embasada na teoria de que o liame imputacional está inserido no âmbito de causalidade normativa, a esfera de risco da atividade previdenciária, por abrandar os riscos sociais a que expostos os segurados, torna imputáveis os prejuízos extrapatrimoniais ao ente previdenciário somente quando a sua atuação resultar em frustração das expectativas legitimamente depositadas pelos segurados. Para caracterização dessa frustração, entendeu-se necessária a constatação do abuso de poder-dever administrativo na interpretação/aplicação da norma previdenciária. Os critérios de aferição dessas margens de razoabilidade de atuação, por sua vez, podem ser objetivamente avaliados considerando a situação do segurado em face da posição jurídica no âmbito do sistema previdenciário

O objetivo deste estudo foi avaliar o efeito do treinamento de força muscular dos membros inferiores na estabilidade postural de mulheres idosas. As participantes (n =21) eram saudáveis, com idade entre 60 e 75 anos (M = 64,4 anos), e foram designadas a um grupo de treinamento (TF) ou a um grupo controle (CO). Esses grupos foram comparados em estabilidade postural e força antes e após um programa de treinamento de força para o grupo TF. A estabilidade postural foi avaliada em posturas eretas estáticas com apoio unipodal e bipodal, e em situações em que a estabilidade postural bipodal foi perturbada de forma previsível ou imprevisível. A perturbação previsível foi produzida por um movimento voluntário, por meio da elevação rápida com as mãos, de cargas conhecidas: 1 Kg, 3 Kg ou 5 Kg. A perturbação imprevisível foi produzida pela alteração inesperada da carga de 3 Kg para a carga de 1 Kg ou de 5 Kg antes de sua elevação. Os resultados indicaram aumento da força muscular após o treinamento de força. Quanto à estabilidade postural, nãob foram observadas diferenças significativas entre os grupos após o treinamento para as tarefas de apoio bipodal e apoio unipodal. A estabilidade postural foi afetada principalmente, quando uma carga mais leve foi elevada na situação imprevisível, gerando maior deslocamento anterior e posterior do CP. Entretanto, não houve efeito do treinamento de força no deslocamento do CP. Após o treinamento de força, o grupo TF apresentou uma redução do tempo de deslocamento posterior do CP e uma redução na variabilidade de amplitude do CP após ajustes compensatórios. Estes resultados sugerem que o treinamento de força não afeta o equilíbrio de idosos em situações estáticas ou componentes de ajustes iniciais com a perturbação da postura, mas houve um efeito positivo nos componentes tardios de ajustes após a perturbação / The goal of this study was to investigate the effect of strength training of the lower limbs on postural stability of older women. Participants (n =21) were healthy, with ages ranging between 60 and 75 years (M=64.4 years); they were assigned to two groups: strength training (ST) and control (CO). These groups were compared for postural stability and muscular strength before and after a strength training program for the ST group. Postural stability was evaluated in uni and bipodal static stance, and in situations of predictable and unpredictable perturbation of balance. The predictable disturbance was produced through the action of lifting a known load (1 kg, 3 kg or 5 kg) with the hands. The unpredictable disturbance was produced by an unexpected alteration of the load of 3 kg to 1 kg or 5 kg right before lifting the load up. The results indicated increased muscle strength after strength training. Regarding postural stability, no significant difference was detected between groups for uni/bipodal static postures. Postural stability was most affected when a lighter weight was lifted in the unpredictable situation, leading to greater anterior and posterior center of pressure (CP) displacement. Strength training, however, had no effect on the initial CP displacement. After training, the ST group showed shorter time of posterior CP displacement and lower variability of CP range after compensatory adjustments. These results suggest that strength training for elderly individuals does not affect stability in static postures or the early component of adjustments to balance perturbation, but it has a positive effect on the late component of adjustments to balance perturbation
