Obesity is a significant public health concern, with implications for the health and well being of millions of people in the United States and world. The purpose of this thesis is to explore the relationship between obesity, segment biomechanics in the form of joint stress and restricted range of motion, and cardiorespiratory fitness. In three studies, anatomical modeling using three dimensional infrared motion capture system was used to calculate joint stresses and range of motion limitations. The results are applied to better understand the impact that obesity has on biomechanics, taking into consideration factors of fitness and fatigue, during walking and common rehabilitation exercises. The first study compared the biomechanical differences between ten obese and ten normal weight adults while performing squat and lunge exercises and found significant increases in lower limb moments in obese females. Increased moments suggest that obese individuals experience higher biomechanical stress than normal weight individuals and may have less flexibility in selecting movement strategies while performing basic rehabilitation exercises. The second study examined how walking, a commonly prescribed exercise to combat obesity, may impact an obese individual's joint biomechanics. While the results of this study, comparing joint stress in ten obese and ten normal weight females, did not observe significant differences between the obese and normal weight groups, stronger relationships were present between moments and VO2 max, rather than BMI, suggesting the importance of fitness in context of developing walking programs. The final study explicitly addressed the relationship between obesity, fitness and biomechanics. Walking and jogging biomechanics was reported in 30 boys and girls, aged 8-11, before and after a fatigue protocol. Hip and knee moments were moderately associated with cardiorespiratory fitness and showed significant increase after cardiorespiratory fatigue. Including measures of adiposity and strength improved the associations between fitness and moments. This thesis concludes that the relationship between biomechanics and obesity, observed in adults and children, should be understood in the larger framework of the reverse causation hypothesis. The reverse causation hypothesis describes obesity as a positive feedback loop, in which certain factors are related to obesity in a bi-directional manner: both causing, but also amplified by, the presence of excess adipose tissue. While further study is required to clarify these relationships, these associations may have implications for participation in physical activities and long-term effects on the musculoskeletal system, thus illustrating the positive feedback loop of the reverse causation hypothesis.

The aim of this master thesis is comparation of simulation tools OptSim™ and PHO- TOSS which are used to create simulations of data traffi cs in access and metropolitan networks. The outcome of this thesis is three laboratory exercises and their theoretical bases which should explain the way of working in diff erent simulation environments to students.

Purpose: The purpose of this study was to determine the effect of word processing on students' composition when used as a tool in the revision/editing stages of the writing process. Procedure: Two experimental groups were established; Group A Computer, Group B No Computer. For each group, the generic method of teaching writing remained the same. Group A, however, was able to use the microcomputer in editing their work; Group B was not. Final essays were scored by independent raters and the data were analyzed by the use of the independent 1-test. A Pearson product -moment correlation coefficient was computed to assess interrater reliability. Conclusion: This study suggests there is a significant positive difference in student writings when the microcomputer is used as a word processor in the revision/editing stages of writing.

"'What about structural linguistics?' many teachers of English are asking today. 'Can it help my students in their quest for acceptable writing habits any more than the tried and tested traditional grammar I've been teaching for years? If so, how?' Let us look at some of the findings of the structural linguists. Maybe we can learn of some new approaches for helping our students become better writers. First of all, let us consider how 'structural signals' play a part in determining the meaning of a sentence. According to Fries, the meaning of an utterance (sentence) is signalled by the way it contrasts with other utterances in word order, by the use of inflections (or form-class words), by the use of 'function words,' and by intonation (pitch and pause patterns in speaking)"--Introduction. / Typescript. / "May, 1958." / "Submitted to the Graduate Council of Florida State University in partial fulfillment of the requirements for the degree of Master of Arts." / Advisor: K.
