Israetel, Michael Alexandrovich. "The Interrelationships of Fitness Characteristics in Division 1 Athletes." Digital Commons @ East Tennessee State University, 2013. https://dc.etsu.edu/etd/1194.
Full textAbstract:
The purpose of this dissertation was to explore the interrelationships of several important fitness characteristics in Division 1 athletes. Sport performance magnitude is the summation of an individual athlete’s technical, psychological, and fitness characteristics. Athletes who excel in any or all characteristics perform better in their chosen sports. General fitness characteristics that are important to almost all sports include strength, power, vertical jump height, shortdistance sprinting ability, muscularity, and body fat percentage. These variables have been shown in previous research to independently affect athletic performance outcomes, but their relationships to one another are less clear. Eighty Division I athletes from 4 sports were examined in a variety of fitness characteristics as part of a continuous athlete monitoring program. Data on strength, power, vertical jump height, short-distance sprinting speed, muscularity, and body fat percentage were collected and analyzed. Analysis revealed several important relationships. Firstly, strength is highly related to muscularity, with lean body mass as one of the most important determinants of strength. Secondly, athletes who can produce high relative (scaled per body mass) forces and powers tend to be considerably higher jumpers and much faster sprinters. Lastly, leaner athletes out-perform less lean athletes in almost every metric, especially relative strength and power, vertical jumping ability, and sprinting ability.

One erythropoietin molecule binds asymmetrically to two identical receptor monomers via erythropoietin site 1 and site 2, although it is unclear how asymmetry affects receptor activation and signaling. Here we report the computational design and experimental validation of two mutant erythropoietin receptors: one that binds only to erythropoietin site 1 but not site 2, and one that binds only to site 2 but not site 1. Expression of either mutant receptor alone in Ba/F3 cells cannot elicit a signal in response to erythropoietin, but when co-expressed, there is a proliferative response and activation of the JAK2 Stat5 signaling pathway. A truncated erythropoietin receptor with only one cytosolic tyrosine (Y343), on only one receptor monomer is sufficient for signaling in response to erythropoietin, regardless of the monomer on which it is located. The same results apply to having only one conserved juxtamembrane hydrophobic L253 or W258 residue, essential for JAK2 activation, in the full-length receptor dimer. We conclude that despite asymmetry in the ligand-receptor dimer interaction, both sides are competent for signaling, and we suggest that the receptors signal equally.

Full textAbstract:
The purpose of this study was to identify the sources of stress experienced by NCAA Division I female ice hockey players at one university. In-depth, open-ended interviews were carried out with six athletes. The data was inductively analyzed according to the guidelines set forth by Cote and colleagues (Cote et al., 1993; Cote et al., 1995). The results of the analysis identified three main categories of stress: (a) the educational demands included academic concerns and time concerns; (b) the hockey pressures included the advantages of playing Division I, hockey performance stressors, training concerns, and the transition to the NCAA; and (c) the relationship issues included family and significant-other relationships, "hockey family" relationships, and social concerns. The connection linking the categories centered on the time concerns and on achieving a successful balance among the educational, hockey, and social pressures. These findings are similar to stressors reported by researchers in a variety of sports.

Full textAbstract:
The way in which an athlete responds to the injury--emotionally, behaviorally, and cognitively--can significantly affect the athlete's mental health in a negative way if not handled appropriately. There are different forms of social support that are known to be helpful with coping during specific stages of injury. The purpose of this study was to examine the relationship between perceived levels of social support and depression symptomatology post injury in Division 1 collegiate athletes at Portland State University (PSU).
Participants were PSU student athletes (n=115). Variables: social support amount (SSQN), social support satisfaction (SSQS), and depression symptomatology (CESD-R) score. Selected injured participants (n=3) completed a 20-minute interview regarding their injury, their social support, and how each affected their mental health.
Females reported more social support sources (SSQN) as well as a higher satisfaction of their social support (SSQS) than males. Non-injured student athletes appeared to have fewer social support sources as well as less social support satisfaction than injured student athletes. Of the total study sample, 27.8 percent met the criteria for some kind of depressive symptom concern.
The study confirmed gender characteristics regarding help-seeking behavior, trends of depression symptomatology, and social support preferences. Overall the current study's findings indicate a need for further research regarding social support and depression symptomatology, examining injured and non-injured student athletes.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIORUm sistema de interrogação de sensores a rede de Bragg utilizando multiplexação no tempo e multiplexação no comprimento de onda é proposto e demonstrado. O sistema apresenta uma solução para a medição de grandezas associadas ao espectro de reflexão de redes de Bragg, possibilitando o aumento do número de sensores a rede de Bragg monitorados através de grandes distâncias em uma mesma fibra óptica, sem um aumento significativo dos custos. O aspecto inovador deste sistema reside na particular associação das seguintes características: o uso de fonte pulsada de banda larga, a disposição, em série, de um grande número de sensores a rede de Bragg de baixa refletividade, a técnica de reutilização dos mesmos comprimentos de onda nominais em grupos contendo vários sensores com comprimentos de onda nominais distintos e um processo de filtragem espectral e análise de sinais pulsados utilizando o filtro DWDM comercial. Aspectos teóricos e experimentais considerando os princípios de trabalho desta técnica são discutidos. Comparações entre resultados simulados e experimentais do sistema implantado mostram boa concordância. Resultados experimentais apontam uma faixa dinâmica de 1,7 nm, podendo encontrar aplicações em medição de temperatura com uma faixa de 150°C. Incertezas com valores médios abaixo de 20 picometros foram obtidas. Simulações experimentais apontam a possibilidade de utilização de um número de aproximadamente 70 sensores com 0,4% de refletividade, por comprimento de onda. Considerando a largura de banda do dispositivo DWDM (1539- 1565 nm) utilizado neste sistema, e um espaçamento de 7 nm por comprimento de onda nominal de sensor, extrapolações mostram que este número pode chegar a 210 sensores em três diferentes comprimentos de onda nominais de sensor. Considerando as bandas C e L este número pode chegar a aproximadamente 1000 sensores em 14 diferentes comprimentos de onda nominais de sensor.
An interrogation system of fiber Bragg grating sensors using time division multiplexing and wavelength division multiplexing is proposed and demonstrated. The system presents a solution to measure the magnitudes associated to the reflection spectrum of the fiber Bragg gratings, making possible to increase the number of the Bragg gratings sensors monitored through large distances at the same fiber optic, without a great increase in the costs. The innovative aspect of this system is the particular association of the following characteristics: the use of a pulsed broad band source, the disposition, in series, of a large number of low reflectivity Bragg gratings sensors, the reusing technique of the same nominal wavelengths in groups containing several numbers of sensors with distinct nominal wavelengths, and a spectral analyzing and filtering process of pulsed signals using a commercial DWDM filter. Theoretical and experimental aspects regarding the working principles of this technique are discussed. Comparisons between experimental and simulated results show a good agreement. Experimental results indicate that a dynamic range of 1,7 nm was obtained. It can be used in temperature measurement systems, with a 150°C range. Uncertainties equivalent to approximately 20 picometers was obtained. Experimental simulations indicate that it would be possible to use a number of approximately 70 sensors with 0,4% reflectivity at each nominal sensor wavelength. Considering the DWDM filter bandwidth (1539-1565 nm) used in this system, and a spectral separation of 7 nm by nominal sensor wavelength, extrapolations indicate that a number of 210 sensors can be obtained, in three different nominal sensor wavelength. Using the C-band and the L-band, a number of 1000 sensors can be obtained, in fourteen different nominal sensor wavelength.

Full textAbstract:
The main goal of this thesis is to explore the idea of gravity as the square of a gauge theory at the level of Lagrangian symmetries. By regarding gravity as the convolution of left and right Yang-Mills theories together with a spectator scalar field in the bi-adjoint representation, we derive in linearised approximation the gravitational symmetries of general covariance, p-form gauge invariance, local Lorentz invariance and local supersymmetry from the at space Yang-Mills symmetries of local gauge invariance and global super-Poincare. As an example, we will we focus on the new-minimal (12 + 12) off-shell version of simple four-dimensional supergravity obtained by tensoring the off-shell Yang-Mills multiplets (4 + 4;N_L = 1) and (3 + 0;N_R = 0). By tensoring all possible pairs of on-shell super Yang-Mills multiplets in dimensions 3 ≤ D ≤ 10 to get on-shell supergravity multiplets, possibly with additional matter multiplets. By associating a (direct sum of) division algebra(s) D with each dimension 3 ≤ D ≤ 10 we obtain a formula for the supergravity U-duality G and its maximal compact subgroup H in terms of the internal global symmetry algebras of each super Yang-Mills theory. We then extend our analysis to include supergravities coupled to an arbitrary number of matter multiplets by allowing for non-supersymmetric multiplets in the tensor product. We also introduce the idea of writing the SYM multiplets themselves as a double copy. We construct the states and symmetries of N = 4 super-Yang-Mills by tensoring two N = 1 chiral multiplets and introducing two extra SUSY generators. This allows us to write the maximal N = 8 supergravity as four copies of the chiral multiplet. We extend this to higher dimensions and discuss possible applications.

Technology use in education is rapidly expanding with varying results. The success of education technologies in schools depends on both the quality of the material presented through technology in terms of content and pedagogy and also the quality of the implementation of the program. With the acknowledgement that high quality materials are essential to the success of any technology, this thesis is concerned with the implementation of technology programs in schools, as it is impossible to utilize the technology for learning gains when students or teachers cannot access the materials. Prior research in education technology has not addressed readiness or planning practices for such large-scale programs as they exist today, specifically for 1:1 initiatives ("1:1" describes a system in which all students have personal learning devices, such as tablets or laptops). The main objective of this thesis is to determine the best practices in preparedness and planning for large-scale technology initiatives in US high schools. The research is designed to aid school system administrators and policy makers in their technology decision-making processes through the creation of a rubric of metrics and a model for sustainable implementation. The rubric and model were informed by data gathered through a case study approach, focusing on schools that are currently implementing 1:1 initiatives. The rubric outlines a spectrum of potential readiness levels across a number of critical metrics and allows school leaders to self-assess their readiness for a 1:1 program. In addition to the rubric and sustainable implementation model, this thesis aims to determine best practices in planning for a 1:1 program. Through a second round of case studies and interviews with school leaders, past planning practices and gaps in knowledge and planning were examined. From the school leaders' reflections on best practices, conclusions for improvement of current planning tools were drawn. These improvements include the creation of mentor relationships for schools and the use of a thorough, yet simple, needs assessment that includes detailed timeline for implementation. Both the readiness rubric and the study of planning practices led to a number of policy recommendations not only for schools, but for all levels of government in support of effective technology use in education.

Full textAbstract:
The treatment of Class II division 1 by jaw upper disorder is a controversial subject in the literature. This study aims to evaluate, through the PAR Index (Peer Assessment Rating), orthopedic treatment of Class II malocclusion division 1 in 15 patients of both sexes who have made growing use of the appliance Thurow modified. This study consisted of a retrospective longitudinal clinical study with no control group. The average age of patients at the start of treatment was 9.3 years for females and 9.4 years for males. The PAR index was obtained from pre and post treatment of each patient. An improvement of 31% or more was considered effective treatment. After descriptive analysis, it was observed that the initial average PAR index of 33 was reduced to 18.5 at the end of treatment, featuring an improved occlusion averaged 43.9%. The treatment was effective in 86.7% of patients, no statistical difference was observed in relation to sex and age at start of treatment (p> 0.05). It was also found that the apparatus provided significant changes in overjet correction (p <0.05). From this study it can be concluded that the orthopedic treatment of Class II division 1 with modified Thurow appliance in growing patients presented a viable alternative, and we observed an improvement of occlusal relationships primarily with respect to overjet and molar relationship towards anteroposterior.O tratamento da Classe II divisÃo 1 por alteraÃÃo maxilar à um assunto controverso na literatura.

Thesis (S.M.)--Massachusetts Institute of Technology, Biological Engineering Division, February 2007.Includes bibliographical references.
Background: Investigators have focused on mechano-regulation of upstream signaling and responses at the level of gene transcription, protein translation and post-translational modifications. Intracellular pathways including those involving integrin signaling, mitogen activated protein kinases (MAPKs), and release of intracellular calcium have been confirmed in several laboratories. Studies with IGF-1: Insulin-like growth factor-I (IGF-1) is a potent anabolic factor capable of endocrine and paracrine/autocrine signaling. Previous studies have demonstrated that mechanical compression can regulate the action of IGF-1 on chondrocyte biosynthesis in intact tissue; when applied simultaneously, these stimuli act by distinct cell activation pathways. Our objectives were to elucidate the extent and kinetics of the chondrocyte transcriptional response to combined IGF-1 and static compression in cartilage explants. Discussion: Clustering analysis revealed five distinct groups. TIMP-3 and ADAMTS-5, MMP-l and IGF-2, and IGF-1 and Collagen II, were all robustly co-expressed under all conditions tested. In comparing gene expression levels to previously measured aggrecan biosynthesis levels, aggrecan synthesis is shown to be transcriptionally regulated by IGF- 1, whereas inhibition of aggrecan synthesis by compression is not transcriptionally regulated.
(cont.) Conclusion: Many genes measured are responsive the effects of IGF-1 under 0% compression and 50% compression. Clustering analysis revealed strong co-expressed gene pairings. IGF-1 stimulates aggrecan biosynthesis in a transcriptionally regulated manner, whereas compression inhibits aggrecan synthesis in a manner not regulated by transcriptional activity.

Day, Jennifer. "Identifying and Reducing Risk of the Female Athlete Triad in Division 1 Athletes." DigitalCommons@USU, 2016. https://digitalcommons.usu.edu/etd/5031.
Full textAbstract:
Physically active females, or female athletes, are at risk for the condition knownas the female athlete triad (Triad). The Triad is made up of three components that are distinctly separate, but intertwined: consuming inadequate energy for how much they are exercising, poor bone health, and problems with their menstrual periods. When female athletes don’t consume enough energy for how much they exercise, there can be hormonal imbalances, causing the body to conserve energy from some important functions including menstruation, and increased bone turnover resulting in a higher risk of stress fractures and early osteoporosis. Female athletes at risk for the Triad have ahigher risk of being injured, and don’t have the energy that they need to perform physically. To combat the Triad, we performed assessments to see how many female athletes were at risk for the Triad in Division I female athletes, and were surprised at the high number that were at risk for the Triad. We provided nutrition information and interventions aimed to decrease female athlete’s risk for the Triad. We also developed anew, quick method for female athletes, or busy individuals, to track their diet using the video feature on their cell phones. The benefits of providing nutrition information to the female athletes included: increasing their knowledge about the Triad, and things that they could do to prevent the Triad. The interventions did cause behavior change in some female athletes to increase how much energy they were consuming, decreasing their risk for the Triad.

Full textAbstract:
Tuberculosis remains a global health problem, exacerbated by the increasing emergence of multi‐drug resistant strains. The identification of new drug targets and the discovery of new anti‐tuberculosis drugs is therefore a high priority. Although little is currently known about mycobacterial cell division, the process is essential for the survival and expansion of all bacterial species so may involve proteins that represent excellent drug targets. In this thesis, proven tools for the study of bacterial cell division such as live‐cell time‐lapse imaging and Fluorescent Repressor Operator System (FROS) were adapted for use in mycobacteria. Application of such techniques, fluorescent tagging of cell division proteins and deletion of parA in M. smegmatis helped to elucidate some interesting characteristics of mycobacterial cell division. In contrast to model organisms, live cell imaging and septal staining indicated that M. smegmatis can grow and divide asymmetrically and divides at a range of lengths suggesting a fundamentally different mechanism of division regulation. The chromosome was hypothesised to play a key role in cell division so was investigated further by labelling a specific chromosomal loci. The key finding was that M. smegmatis cells only contain 1 or 2 chromosomal copies and that regardless of cell length, the nucleoid occupies almost the entire intracellular space. To examine if the nucleoid organisation is important for cell division, a putative chromosome segregation gene parA was disrupted. The ΔparA mutant displayed a classic cell division phenotype characterised by the production of anuclear mini‐cells. The mechanism responsible for the ΔparA mutant phenotype was studied further by applying live cell imaging, FROS and expressing a ParA‐mCherry fusion protein. The data obtained from all work presented was collated and used to propose a novel model of bacterial cell division regulation applicable to mycobacteria where the nucleoid plays a central role and ParA is required to ensure correct nucleoid placement.

Full textAbstract:
There has been increasingly interest in parental leave policies as instruments for the implementation of gender equality in society. This review essay explores the link between parental leave policies and the gender division of labour - referring to both paid employment and unpaid family work. Against this backdrop the essay systematically reviews evidence from quantitative empirical research on the effects of parental leave policies on mothers' employment and fathers' involvement in family work. The article suggests that there are several aspects of parental leave that seem to be especially relevant for the gender division of labour, such as the duration of leave, the provision of payments, and an individual entitlement of non-transferable leave rights. In a concluding section the article summarizes the results, discusses doubts and questions raised by the material and identifies promising areas of future research that are crucial for a better understanding of the effects of parental leave on the gender division of labour.

Full textAbstract:
Bakgrund: Enligt Skolverkets rapporter av de internationella studierna TIMSS 2007 (Skolverket, 2008) och TIMSS 2011 (Skolverket, 2012) påpekas det att matematik-kunskaperna hos svenska elever har försämrats. I dessa rapporter framkommer bland annat att de flesta svenska eleverna inte når TIMSS kunskapskala för division. Räknesättet division är enligt Häggblom (2000) det svåraste räknesättet för eleverna att förstå och Löwing (2008) menar att svårigheterna beror på att våra elever inte förstår att man kan tänka och räkna division utifrån två olika aspekter, delningsdivision och innehållsdivision. Forskning visar att matematikundervisningen styrs av matematikläroböcker och enligt McIntosh (2008) behandlas divisionsaspekten delningsdivision mer än innehållsdivision i undervisningen vilket betyder att eleverna inte får möjligheten att arbeta med båda aspekterna lika mycket. Syfte: Studiens syfte är att undersöka hur divisionsaspekterna delningsdivision och innehållsdivision behandlas i matematikläroböcker och lärarhandledningar för årskurs 1-3. Metod: För att besvara studiens frågeställningar har studien genomförts utifrån tre olika innehållsanalysmetoder. Dessa är; kvalitativ, kvantitativ och komparativ innehållsanalys. Utifrån dessa och med hjälp av McIntosh (2008) definitioner om divisionsaspekterna analyserades tre olika matematikläroboksserier med tillhörande lärarhandledningar. Resultat: Resultatet visar i vilken årskursbok division och dess aspekter introduceras och på vilket sätt kapitlen är strukturerade. I samtliga böcker behandlas division i samband med multiplikation och räknesätten arbetas alltid parallellt med varandra. I ett av läromedlen behandlas även division i samband med upprepad addition medan i de andra två uppmanas endast i lärarhandledningen att arbeta med division i samband med upprepad subtraktion. Studien visar också att samtliga granskade matematikläroböcker och lärarhandledningar behandlar båda divisionsaspekterna men hanteringen varierar mellan läromedlen. Resultatet visar att matematikläroböckerna innehåller en ojämn fördelning av divisionsaspekterna och det är fler uppgifter med innehållsdivisions än delningsdivision. Då tidigare forskning pekar på att matematikundervisning styrs av läroböcker, ges elever i lågstadiet färre möjligheter att lära sig räknesättet division utifrån aspekten delningsdivision.

Full textAbstract:
The bioactive lipid sphingosine-1-phosphate (SIP) has the unique characteristic of being capable of engaging in both paracrine/autocrine signalling and intracrine signalling pathways. Research into the latter has been limited by the failure to identify downstream targets for intracellular S1P. The majority of cellular responses to S1P are mediated by a family of G-protein coupled receptors (GPCR) known as S1P receptors: SIP₁₋₅. The current study demonstrates that SIP₅ and both sphingosine kinases (SPHK1 and SPHK2) exhibit a unique intracellular localization in the centrosome of mammalian cells.

The period in which the plants remained under saline condi-tions before the collection was 50, 40, 30 and 20 days in T2, T3, T4 and T5, respec-tively. In the second experiment it was also compared four periods of salinity (CE 5.0 dSm-1) and control (CE 1.0 dSm- 1). The planting was done on the same day of the experiment I and the supply of saline solution began on the same day of the first trial, but the harvest was delayed in order to increase the periods in which the plants re-mained in saline conditions. All plants were collected on 12 February 2015. Thus, the salinity period before the collection was 110, 100, 90 and 80 days for treatments T2, T3, T4 and T5, respectively. In both experiments the experimental design was ran-domized with five replications. The Extraction of oil from the leaves by hydrodistilla-tion in Clevenger was performed and then performed gas chromatography. The es-sential oil was evaluated for antiproliferative and genotoxic effects in cells of Allium Cepa at a concentration of 0.20 % for the oil of plants grown in different periods of salinity collected at 190 after planting. The biomass production data and essential oil were subjected to analysis of variance with polynomial regression and other data were compared by Scott-Knott test (p <0.05). The results showed that the salinity period through a nutrient solution with electrical conductivity of 5 dS m-1 linearly re-duces biomass, content and essential oil yield of rosemary plants in soilless culture. The major compounds of the essential oil were camphor, 1.8 cineol, verbenone, α-pinene and β-myrcene. And this in turn was not genotoxic nor showed significant an-tiproliferative effect, except that obtained from the plants that remained for a longer period of exposure to salinity, which inhibited cell division of Allium Cepa.
Rosmarinus officinalis L. é uma espécie que tem se destacado pelo seu intenso uso popular, tendo como principal produto o óleo essencial. O trabalho teve como objetivo determinar o efeito do período de salinidade sobre a fitomassa, teor, rendimento, composição fitoquímica e genotoxicidade do óleo essencial das folhas de alecrim. Dois experimentos foram realiza-dos simultaneamente no período entre 3 de junho de 2014 a 12 de dezembro de 2015, os experimentos foram realizados no Departamento de Fitotecnia da Universidade Federal da Santa Maria. No experimento I, na testemunha (T1) foi empregada uma solução nutritiva com condutividade elétrica (CE) de 1,0 dSm-1 e nos demais quatro tratamentos (T2,T3,T4,T5) foi empregada uma solução nutritiva com condutividade elétrica de 5,0 dSm-1. Em T2 o fornecimento da solução salina foi iniciado aos 140 dias após o plantio (DAP), em T3 aos 150, em T4 aos 160 e em T5 aos 170 DAP. Todas as plantas foram coletadas no dia 12 de dezembro de 2014 completando um período de 190 dias. O período no qual as plantas permaneceram sob condições salina antes da coleta foi de 50, 40, 30 e 20 dias em T2, T3, T4 e T5, respectivamente. No experimento II também foram utilizados quatro perío-dos de salinidade (CE de 5,0 dSm-1) e a testemunha (CE de 1,0 dSm-1). O plantio foi feito no mesmo dia do experimento I e o fornecimento da solução salina iniciou-se nos mesmos dias do experimento I, porém a colheita foi retardada de forma a aumentar os períodos nos quais as plantas permaneceram em condições salinas. Todas as plantas foram coletadas no dia 12 de fevereiro de 2015. Dessa forma, o período de salinidade antes da coleta foi de 110, 100, 90 e 80 dias nos tratamentos T2, T3, T4 e T5, respectivamente. Em ambos os experi-mentos o delineamento experimental empregado foi casualizado, com cinco repetições. Foi realizada extração de óleo das folhas por hidrodestilação em Clevenger e posteriormente realizada cromatografia gasosa. Os óleos essenciais foram avaliados quanto aos efei-tos antiproliferativo e genotóxico em células de Allium cepa L. na concentração de 0,20 % para o óleo das plantas cultivadas nos diferentes períodos de salinidade coletadas aos 190 depois do plantio. Os dados de produção de fitomassa e rendimento de óleo essencial foram submetidos à análise de variância com regressão polinomial e os demais dados foram com-parados pelo teste Scott-Knott (p<0,05). Os resultados mostraram que o período de salini-dade através de uma solução nutritiva com condutividade elétrica de 5 dS m-1 reduz linear-mente a fitomassa, teor e rendimento de óleo essencial de plantas de alecrim em cultivo sem solo. Os compostos majoritários do óleo essencial foram cânfora,1,8 cineol, verbenona, α-pineno e β-mirceno. E esse, por sua vez não se mostrou genotóxico e nem apresentou efeito antiproliferativo significativo, com exceção daquele obtido a partir das plantas que permaneceram por um maior período de exposição à salinidade, que inibiu a divisão celular de Allium cepa.

CAPES
O presente trabalho trata de uma pesquisa de mestrado que teve como objetivo investigar que estratégias alunos da 2ª fase do 2º ciclo (5º ano do Ensino Fundamental de nove anos) que frequentam a sala de articulação de uma Escola Estadual no município de Várzea Grande, em Mato Grosso, mobilizam na Resolução de Problemas de Divisão. A estratégia é definida nesta dissertação, segundo Palhares (2004), como um conjunto de técnicas a serem dominadas pelos solucionadores ajudam o aluno a resolver o problema ou progredir no sentido de encontrar a sua solução. A pesquisa foi delineada pela seguinte problemática: Que estratégias os alunos da 2ª fase do 2º ciclo (5º ano do Ensino Fundamental de nove anos) que frequentam a sala de articulação de uma Escola Estadual de Várzea Grande, em Mato Grosso, mobilizam na Resolução de Problemas matemáticos de divisão? Levando em consideração a natureza dessa pesquisa, a metodologia de investigação adotada foi uma abordagem qualitativa e se configura em um estudo de caso, em que nos baseamos nos autores Fiorentini; Lorenzato (2012); Yin (2010); Bogdan; Biklen (1994) e Merriam (1998). A pesquisa foi desenvolvida em três momentos: no primeiro momento fizemos um levantamento das pesquisas brasileiras que discutem a Resolução de Problemas de divisão, com o objetivo de conhecer o que os autores dizem sobre essa temática. Sendo assim, a base teórica sobre resolução de problemas é embasada por Onuchic (1999, 2011), Onuchic; Allevato (2009), e Sánchez Huete; Fernández Bravo (2006), entre outros. Em relação à resolução de problemas, como metodologia de ensino, buscou-se suporte em Onuchic (2011); Brasil (1997); entre outros. Quanto à definição de estratégia na resolução de problemas, utilizamos as definições de Sánchez Huete; Fernández Bravo (2006) e Palhares (2004). Mediante o referencial teórico citado num segundo momento, aplicamos um estudo piloto com o objetivo de avaliar a metodologia de coleta de dados. O terceiro momento de nossa investigação estabeleceu-se com alunos da 2ª fase do 2º ciclo (5º ano do Ensino Fundamental) que frequentam a sala de articulação em uma escola estadual no município de Várzea Grande-MT. As estratégias mobilizadas pelos alunos foram identificadas por: desenho; algoritmo da divisão com chave longa; algoritmo da divisão com chave breve; algoritmo da multiplicação; algoritmo adição e algoritmo subtração. Como resultado, temos que os alunos da sala de articulação têm muitas dificuldades com as operações, especialmente com a de divisão, não conseguem identificar nos problemas as operações matemáticas, o que justifica pelo fato de alguns alunos estarem em fase de alfabetização e, por isso, fazem tentativas, buscando acertar qual operação deverá ser utilizada na resolução.
This paper deals with a Master thesis aimed to investigate which strategies students of Stage 2nd level of the 2nd cycle (5th year of elementary school for students of nine years) attending the resource room of a state school in the count of Várzea Grande, in Mato Grosso, how they manage the Solve Problem Division. The strategy is defined in this dissertation, according Palhares (2004), as a set of techniques to be mastered by solvers helps the student to solve the problem or progress towards finding a solution. This research was designed with the following problem: What strategies students from Stage 2nd of the 2nd cycle (5th year of elementary school for students of nine years) attending the resource room of a State School of Várzea Grande, Mato Grosso, how they manage the Mathematical Problem Divison? Considering the nature of this research, the research methodology adopted was a qualitative approach and is configured in a case study, in which we relied on the authors Fiorentini; Lorenzato (2012); Yin (2010); Bogdan; Biklen (1994) and Merriam (1998). The research was developed in three stages: at first we did a survey of Brazilian research discussing the Solve Problem Division, with the aim of knowing what the authors say about this subject. Thus, the theoretical basis for problem solving is grounded by Onuchic (1999, 2011), Onuchic; Allevato (2009) and Sánchez Huete; Fernandez Bravo (2006), among others. Regarding the definition of strategy in solving problems, we use the definitions of Huete Sánchez; Fernandez Bravo (2006) and Palhares (2004). Through the theoretical framework mentioned subsequently, applied a pilot study aiming to assess the methodology of data collection. The third stage of our investigation it was established with students from Stage 2 of the 2nd cycle ( 5th year of elementary school ) attending the living joint in a state school in the count of Várzea Grande- MT. The strategies deployed by students were identified by: design; long division algorithm with key; division algorithm with short key; algorithm of multiplication; addition and subtraction algorithm. As a result, the students of the resource room have many difficulties with operations, especially with the division, They fail to identify problems in mathematical operations, which explains the fact that some students are beginning literacy and therefore make attempts, trying to hit what operation should be used in the resolution.

Full textAbstract:
La division cellulaire est cruciale pour le maintien de la stabilité du génome. Or, les gènes régulateurs de la mitose sont fréquemment mutés dans le cancer. Les cellules cancéreuses possèdent généralement un nombre anormal de chromosomes et la majorité des tumeurs solides sont aneuploïdes. Cette caractéristique favorise notamment l'initiation et la progression tumorale mais constitue également un facteur de mauvais pronostic et de résistance thérapeutique. La voie sphingosine kinases/sphingosine 1-phosphate (SphKs/S1P) régule la prolifération et la survie cellulaire, l'apoptose, la migration ou encore la réponse inflammatoire. De nombreuses études ont montré que sa surexpression favorise l'initiation et la progression tumorale mais également l'invasion, le processus métastatique et l'acquisition de résistance à la thérapie. Mon projet de thèse vise à mettre à évidence le rôle de la voie SphKs/S1P dans la régulation de la mitose et de la ségrégation chromosomique. Nos résultats montrent pour la première fois que les SphKs contrôlent la progression mitotique. Cette régulation implique la production de S1P et son interaction avec son récepteur couplé aux protéines G, le S1P5. La surexpression des SphKs ou la surproduction de S1P altèrent la ségrégation des chromosomes. De plus, nos données récentes suggèrent que la voie SphKs/S1P puisse être impliquée dans l'acquisition de résistance aux agents de chimiothérapie ciblant la mitose. Nous montrons pour la première fois que la voie SphKs/S1P est un nouveau régulateur de la mitose. Ces travaux permettent de mieux comprendre comment la voie SphKs/S1P contribue au développement tumoral et renforcent leur intérêt comme cible thérapeutique dans le traitement du cancerCell division is a crucial process for genome maintenance. In cancer, numerous regulators of mitosis are mutated or altered, impeding the quality of chromosome segregation. Tumors exhibit a high chromosomal instability and are frequently aneuploid. These hallmarks promote tumor initiation and progression but are also associated with poor prognosis and therapeutic resistance. The sphingosine kinases/sphingosine 1-phosphate (SphKs/S1P) pathway is a key regulator of several fundamental biological processes including cell proliferation, survival, apoptosis, migration or inflammatory response. Numerous studies have shown that the up-regulation of the SphKs/S1P pathway promotes tumor initiation and progression, invasion, metastasis and resistance to anticancer therapies. We are interested in the role of the SphKs/S1P pathway in cell division regulation. Our data indicate for the first time that SphKs regulate mitotic progression trough S1P production and the interaction with its G protein-coupled receptor S1P5. Furthermore, we showed that the up-regulation of the SphKs/S1P pathway impairs chromosome segregation. Finally, our recent data suggest that the SphKs/S1P pathway may be involved in the acquisition of resistance to mitotic chemotherapeutic agents. Overall, we have identified the SphKs/S1P/S1P5 pathway as a new genuine regulator of mitosis. We give support to the understanding of the implication of the SphKs/S1P pathway in tumoral progression and strengthen its interest as anti-cancer therapeutic targets

Full textAbstract:
Background: The correction of Class II malocclusions is one of the most common treatments performed in the United States. Despite Class II malocclusions being one the most commonly presented problems for orthodontists, there is no consensus of which non-surgical treatment modality best impacts a patient’s quality of life long term.
Purpose: This study examines the different non-surgical treatment approaches for patients with severe Class II division 1 and the impact of treatment outcomes on patient satisfaction and quality of life long term.
Study Design: This study retrospectively analyzed the different treatment approaches and outcomes of class II division 1 with severe overjet, while prospectively assessing patient satisfaction and quality of life long term. Initial and final cephalometric and clinical variables for 83 patients (38 at Harvard School of Dental Medicine, 30 at the University of Iowa, and 15 in private practice in Iowa) treated non-surgically were recorded and analyzed. A retention clinical exam, at least 6 months post-debond, was done for final measurements, assessment of practitioner and patient satisfaction, and patient quality of life questionnaires.
Results: Non-surgical treatment of severe Class II division 1 malocclusions yielded 5.54 mm overjet reduction and 0.51 mm of relapse in retention on average. Patients with more overjet at their long term retention check demonstrated significantly poorer satisfaction scores with the appearance of their bite (p<0.001), the appearance of their face (p<0.001), and with their overall orthodontic treatment (p<0.001). Extraction treatment was associated with significantly lower patient satisfaction scores of overall orthodontic treatment (p=0.023) and appearance of bite (p=0.018) but not facial appearance. Patients treated with extractions also showed higher QOL scores on the OHIP-14 (p=0.022) and CPQ (p=0.002) surveys, indicating that extraction therapy of severe Class II division 1 patients led to a significantly poorer quality of life.
Conclusion: Non-surgical treatment of severe Class II division 1 malocclusions can yield excellent results and stability long term. Overjet can be dramatically reduced with non-surgical treatment but there is a tendency for overjet to relapse in retention. While treatment outcomes yielded high results of patient satisfaction, patients with more overjet in retention displayed significantly less satisfaction of the appearance of their bite, appearance of their face, and with their overall orthodontic treatment. Extraction treatment was associated with significantly lower patient satisfaction scores of overall orthodontic treatment and appearance of bite but not facial appearance. Patients treated with extractions showed poorer quality of life scores in retention compared to those treated nonextraction.

The purpose of this investigation was to develop a new prediction equation for 1RM bench press performance in Div. I college football players using both submaximal lifts and anthropometric variables. One repetition maximum (1-RM), 5-RM, reps at 225 lbs, and various anthropometric variables were collected on 85 Div. I college football players. Mean and SD were found for the following variables: height 182.3 cm ± 7.2; weight 102.0 kg ± 21.5; age 19.8 yrs ± 1.3; 1-RM 308.9 lbs ± 59.2; 5-RM 261.8 lbs ± 51.2; 225lb repetitions 14.1 reps ± 8.1; upper arm length 37.9 cm ± 2; CSA 125.5 cm2 ± 24.8; and flexed arm 41.2 cm ± 4.2. Findings indicated that the performance variables accounted for the majority of the explained variance; however, anthropometric factors also made a meaningful contribution to the explanation of 1-RM bench press strength. The equation generated in this study produced an R2 of 0.93 with a SEE ± 6.6 kg. Often previously published prediction equations investigated in this study, the equation developed in the current study was the only equation that did not significantly differ from actual 1-RM scores for a cross-validation sample of 31 subjects (p = 0.37). By combining anthropometric factors with performance variables, the current equation was able to predict 87% of individuals within ± 20 lbs of their actual 1-RM bench press performance. Therefore, it was concluded that the equation developed in this study is a valid means of estimating 1-RM bench press strength in Div I college football players.vii, 69 leaves

Introduction: Successful treatment of class II Division 1 malocclusion is also implied to the long-term stability of treatment changes and many are the factors that can influence that. Objective: This research aimed to evaluate the long-term stability of the cephalometric changes obtained during Class II malocclusion correction with the MARA (Mandibular Anterior Repositioning Appliance) associated with fixed appliances. Methods: The treatment group comprised 12 patients who were evaluated at three stages: pretreatment (T1), posttreatment (T2) and long-term posttreatment (T3). The mean initial age of the patients was 12.35 years and the mean final age was 15.65 years. The mean age at the long-term posttreatment stage was 22.53 years and the mean long-term posttreatment period was 6.88 years. The control group comprised 12 subjects with normal occlusion and no orthodontic treatment with ages comparable to the treatment group at the posttreatment and long-term posttreatment stages. Intra-treatment group comparison between the three stages was performed with repeated measures analysis of variance (ANOVA), followed by Tukey tests. Intergroup comparison of posttreatment changes and normal growth changes of the treatment group were performed with t tests. Results: reduction of the maxillary protrusion and improvement of the maxillomandibular relationships remained stable during the long-term posttreatment period. Maxillary incisors inclination and overjet presented a tendency to relapse in relation to the control group Conclusions: Despite the different amount of growth potential, the reduction of the maxillary protrusion and maxillomandibular relationship improvement remained stable with no difference from normal occlusion behavior. Palatal inclination of the maxillary incisors and the overjet improvement showed a slight tendency towards relapse when compared to normal occlusion. Therefore, an increase of active retention time could be recommended to prevent that.Introdução: o tratamento bem-sucedido da má oclusão de classe II Divisão 1 está implícito na estabilidade em longo prazo das correções e muitos são os fatores que podem influenciar esta estabilidade. Objetivos: observando que a terapia com o aparelho MARA (Mandibular Anterior Repositioning Appliance) associado ao aparelho ortodôntico fixo mostrou-se eficaz na correção da Classe II, este trabalho estabeleceu como objetivo avaliar cefalometricamente a estabilidade em longo prazo das correções obtidas durante este tratamento. Materiais e métodos: foram analisadas as alterações durante e após o tratamento através das telerradiografias em norma lateral de 12 pacientes (09 meninos e 03 meninas) nas fases: inicial (T1), final (T2) e pós-tratamento (T3), com idade média inicial de 12,35 anos e 15,65 anos ao final do tratamento. A idade media no estágio de pós tratamento em longo prazo foi de 22,53 e o tempo de acompanhamento pós tratamento foi em media 6,88 anos. As alterações foram comparadas a um Grupo Controle com oclusão normal, não tratados ortodonticamente, com idades compatíveis ao grupo experimental nos estágios final e pós tratamento em longo prazo. Os dados obtidos foram analisados através da análise de variância (ANOVA) para medidas repetidas e o teste de comparações múltiplas de Tukey. As alterações ocorridas no período de póstratamento foram comparadas com as alterações do Grupo Controle durante o período correspondente utilizando o teste t independente. Resultados: Observou-se uma redução da protrusão maxilar, assim como, uma melhora das relações maxilomandibulares, as quais, permaneceram estáveis durante o período de póstratamento. A inclinação dos incisivos superiores e o overjet apresentaram tendência à recidiva em relação ao grupo controle. Conclusões: A redução da protrusão maxilar e melhora da relação maxilomandibular mantiveram-se estáveis, sem diferença estatisticamente significante do comportamento na oclusão normal. A retroinclinação dos incisivos superiores e a melhora do overjet mostraram uma ligeira tendência à recidiva quando comparada ao comportamento da oclusão normal. Portanto, um aumento do tempo de retenção ativo pode ser recomendado para evitar essa recidiva.

Introduction: Class II Division 1 malocclusions are characterized by a retrusive mandible and prominent upper incisors. Despite Class II malocclusions being one of the most frequently treated cases in orthodontists' office, there is no uniform consensus in the orthodontic community on the best treatment modality and biomechanical approach to use in treating patients with Class II malocclusions.
Purpose: This paper examines the end-of-treatment outcomes of severe Class II Division I malocclusion patients treated with surgical versus non-surgical approaches.
Study Design: This is a retrospective study of consecutively treated severe Class II Division I patients at the University of Iowa. Initial and deband lateral cephalometric radiographs were compared between 45 non-surgical and 21 surgical patients. All patients that were debanded between the ages of 13 to 19 years were included. Multivariable regression analyses were used to examine differences in outcomes between treatment groups.
Results: Following adjustment for patient level confounders (age, gender, and race), those treated surgically had better end of treatment cephalometric outcomes. Those treated surgically had a more balanced skeletal profile, greater reduction in overjet, and improvement in ANB angle (p
Conclusion: Orthodontic treatment in conjunction with orthognathic surgery is a more ideal treatment for patients with severe Class II Division I malocclusion. When treated surgically, a greater amount of overjet can be reduced while keeping lower incisors in a more stable position in bone.

Full textAbstract:
Background Keller (2009) states that brand equity and the crucial intangiblevalue a brand brings to organizations is perhaps one of the most important marketing topics discussed in recent years. As the competitive market and branding environment for companies are fierce, the sport industry has gradually become more competitive and professional in many aspects of their operations as well. Researchers have gone to the extent of claiming that a brand is the most important asset of a sports team and that the brand provides direction and meaning for sports associations as well as for their followers. Still, market studies have indicated that sport associations often lack appropriate branding strategies and particularly for teams below the professional level, research have been limited in these areas. Purpose The purpose of this thesis is to examine what strategies and actions lower level Swedish ice hockey teams use in order to create and strengthen their brand. Method A hermeneutic view and inductive approach have been applied for this thesis. The purpose and research questions of this thesis have been answered with the help of seven qualitative, semistructured in-depth interviews with lower level sport club managers. Frame of reference Theory is based on two approaches to how teams can build and leverage their brand. While a model by Richelieu (2003) illustrates a strategic construction of the sports brand, the Spectatorbased brand equity model by Ross (2006) is more concerned with how controllable and uncontrollable factors contributes to the two main components of spectator based brand equity, namely brand awareness and brand associations. Conclusions The conclusion withholds the answer to the four research questions and purpose designed for this thesis. The findings indicate that teams are starting to realize the importance of a strong brand, particular to meet increased customer expectations for the game experience are considered important to create positive brand associations. An important finding have been the lack of communication and interaction teams seem to have with their customers in order to establish a clear brand identity and position in the market. The findings also indicate some characteristics particular to the lower level setting e.g. the dependence on volunteer workers and how the lack of long-term financial responsibility have impacted the management and development of a strong brand.

Full textAbstract:
Jump ability is important in volleyball; therefore analysis of factors that influence jump performance is necessary to ensure maximal jump ability. Purpose: To analyze how strength characteristics associated with jumping are affected by percent body fat, lean body mass and free fat mass. Methods: Data from eleven female NCAA DI volleyball players as part of an ongoing athlete monitoring program collected from 2007-2010 was analyzed. Data was separated into weakest and strongest based on isometric peak force allometrically scaled. In all cases the weakest data corresponded to testing during the athletes first year at ETSU. Body composition was measured using air displacement plethsmography (BodPod). Maximum strength (isometric peak force – IPF) and strength characteristics (peak force -F@ 50ms, 90ms, and 250ms; rate of force development, 0-200ms –RFD) were measured with isometric mid-thigh pulls on a force plate, and countermovement jumps with 0, 11 and 20 kg . Allometric scaling of the different force values (IPFa, F@50a, F@90a, F@250a) was used to normalize differences in the body mass of the athletes (absolute force/ (body mass (kg0.67)). Pearson correlations were used to determine the relationship strengths. Results: In weaker test results, there are moderate and small inverse correlations between CMJ and PF (r=-0.34) and PFa (r= -0.19), and strong inverse correlations between CMJ and percent body fat (r=-0.67). In stronger test results there are small correlations between CMJ and PF (r=0.23), PFa (r= 0.26), and moderate inverse correlations between CMJ and percent body fat (r=-0.40). There is a significant change in jump ability and strength between both groups. Conclusion: As an athlete becomes stronger, there is a significant correlation between CMJ strength, PF, PFa, F250, and F250a.

The purpose of this study was to investigate the alterations and relationships among training variables, performance variables, and physiological variables. Nine (9) D-1 collegiate throwers and 4 control subjects participated in the study. The throwers participated in an 11-week periodized resistance training and throws program. Volume load was recorded throughout the study. Measurements of maximal strength (isometric mid-thigh pull), vertical jumping ability, dynamic mid-thigh pulls (across a spectrum of loads), hormones (testosterone and cortisol), and adipokines (adiponectin, leptin, and resistin) were taken at weeks 1, 7, and 11. The throwers demonstrated several statistically significant alterations over time for performance variables. The throwers realized increases across time in maximum strength and peak power output. Hormone values did not exhibit statistically significant changes across time; however, there were trends across time for cortisol, the testosterone:cortisol ratio and adiponectin. These alterations would indicate a more anabolic environment and less obesity associated inflammation.

Introduction: Conceptually, it is important to understand the underlying physiological mechanisms of any training program model. This understanding aids the coach/sport scientist in making better choices in manipulating variables in formulating the training model. These underlying mechanisms can be associated with training variable manipulation, fatigue management aspects and the overall health of the athlete. Hormone and cytokine concentrations can be linked to alterations resulting from the manipulation of training variables and to subsequent alterations in performance. For example, alterations in the testosterone: cortisol ratio (T:C) has been associated with alterations in training volume as well as physiological aspects such as lean body mass, fat content and strength/power performance. Although cytokine production is part of the adaptive process, markedly increased/excessive cytokine production has been related poor fatigue management and over training. Purpose: The purpose of this study was to investigate the alterations and relationships among training variables, and physiological variables. Subjects: Nine (9) D-1 collegiate throwers and 4 control subjects participated in the study. Methods: The throwers participated in an 11- week periodized resistance training and throws program. Volume load was recorded throughout the study. Hormone (testosterone and cortisol (C), and adipokine (adiponectin, leptin, and resistin) measurements were taken at weeks 1, 7, and 11 for the throwers. Results: Hormone values did not exhibit statistically significant changes across time; however, there were trends across time for C, the T:C ratio and adiponectin. Conclusions: Based on the hormonal and adipokine data, it appears that the training program produced some positive effects. These effects indicate a reasonable degree of fatigue management in that C decreased and the T:C ratio was increased as volume load decreased. Literature supports the idea that increases in adiponectin may be a positive outcome of a sound training protocol (Smith et al., 2000). The present observation indicates that adiponectin increased in concert with decreases in C and increases in the T:C. ratio. Considering the effects of these hormones and cytokines, these alterations over time indicate a lesser degree of obesity related inflammation and a higher degree of “fitness” and preparedness

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIORAs técnicas de múltiplo acesso mais cogitadas nas propostas para padrões de 3 geração de sistemas celulares envolvem alguma forma de CDMA ( Code Division Multiple Access)na qual os usuários podem transmitir simultaneamente na mesma faixa de freqüência sendo separáveis no receptor pela ortogonalidade, ou quase ortogonalidade, entre os sinais utilizados pelos diferentes usuários para transmissão de informação.Os receptores multiusuário, propostos para uso na 3 geração de sistemas celulares, realizam a detecção do sinal do usuário desejado conjuntamente com os sinais interferentes, resultando em um ganho de desempenho em relação aos receptores CDMA convencionais, que tratam os sinais interferentes como um simples ruído de fundo.Este trabalho tem por objetivo estudar a viabilidade de um receptor CDMA multiusuário hpibrido síncrono, que combina a eficiência do recepor Decorrelator no combate a interferência de múltiplo acesso (IMA) e sua simpicidade de implementação com a robustez e alto desempenho do receptor ótimo. Para evitar a complexidade inerente a estrutura de detecção ótima é sugerido que o conjunto de sinais na saída do estágio Decorrelator seja particionado em grupos e detectados de forma paralela e ótima. Esta técnica é conhecida como detecção ótima por grupos. Também é proposto e explorada a utilização de uma métrica para a formação dos grupos, baseada na minimização da probabilidade de erro de bit do usuário com pior desenpenho no sistema. Ao longo deste trabalho são exibidos resultados analíticos e de simulação, que comprovam a utilidade e exelente relação entre desempenho e complexidade da estrutura proposta em canais AWGN. Por fim, a estrutura proposta é avaliada para um canal com desvanecimento de Rayleigh plano.
The most discussed multiple access techiniques for the 3G of mobile wireless systems involve some form of CDMA - Code Division Multiple Access- where the users can transmit simultaneously their signals in the same frequency band separable in the receiver by the orthogonality or, quasi- orthogonality, properties of the transmitted signals. Multiuser detectors MUD perform the detection of the desired user signal jointly with the signals transmitted by the remaining users, resulting in a better performance than the conventional CDMA receivers, that treat the interference created by the signals of other users simply as background noise.This work has the objective of investigating the viability of syncrhronous hybrid multiuser detector, wich combines the implementation simplicity and efficiency of the decorrelating multiuser detector in mitigating the multiple access interference with the robustness and high performance of the optimum multiuser detector.In order to avoid the complexity of the optimum multiuser detection scheme it is proposed to combine the signals from the decorrelator output into groups and perform optimal detection of the signals in each group. This approach is known as optimal group detection. Also in this work, a strategy on how to perform the grouping is proposed and explored. This strategy is based on the minimization the bit error probability of the user with the worst performance.Simulation and analytical results show the excellent trade-off between performance and complexity of the proposed optimum multiuser group detector in AWGN channels. The receiver performance is also evaluated in Rayleigh flat fading channels.

Full textAbstract:
The purpose of this investigation was to evaluate the relationships between two types of vertical jumps and change of direction (COD) test in collegiate soccer players (n=24). 5-5 COD test was utilized to measure soccer athletes’ COD ability. 3m acceleration (3mAcc), Total time (TT) and Partial time (PT) were measured by two sets of timing gates. Countermovement jump (CMJ) and static jump (SJ) with 2 different loading conditionings (0kg and 20kg) were employed to evaluate athletes’ leg dynamic strength. Strong statistically significant relationships were found between COD test variables (r =0.71 to 0.90), and between vertical jump variables with PT and TT (r = -0.41 to -0.81). These results suggest that leg dynamic strength is vital for NCAA Division I soccer players’ COD performance and SJ 0kg jump height can be used to predict for COD performance.

Full textAbstract:
The purpose of this study was to determine if NCAA Division I-A football program success had a relationship to student-athlete graduation rates. Graduation rate data for 2001 were obtained from the NCAA and cumulative five-year records of selected NCAA Division I-A football programs determined winning percentage for the years 1996-2000. The data were examined by correlating the two variables of winning percentage and graduation rate. The findings show no significant correlation at a probability level of .05. The results of this study indicate the success of a football programs do not have any relationship to low football team graduation rates. Therefore, other factors such as athletic department ideals, commercialization of sport, or the preconceived notion that collegiate football athletes are only enrolled to compete in football may play a factor in graduation rates among NCAA Division I-A football players.
