Full textAbstract:
L'Internet Physique (IP) est une initiative qui identifie plusieurs symptômes d'inefficacité et non-durabilité des systèmes logistiques et les traite en proposant un nouveau paradigme appelé logistique hyperconnectée. Semblable à l'Internet Digital, qui relie des milliers de réseaux d'ordinateurs personnels et locaux, IP permettra de relier les systèmes logistiques fragmentés actuels. Le but principal étant d'améliorer la performance des systèmes logistiques des points de vue économique, environnemental et social. Se concentrant spécifiquement sur les systèmes de distribution, cette thèse remet en question l'ordre de magnitude du gain de performances en exploitant la distribution hyperconnectée habilitée par IP. Elle concerne également la caractérisation de la planification de la distribution hyperconnectée. Pour répondre à la première question, une approche de la recherche exploratoire basée sur la modélisation de l'optimisation est appliquée, où les systèmes de distribution actuels et potentiels sont modélisés. Ensuite, un ensemble d'échantillons d'affaires réalistes sont créé, et leurs performances économique et environnementale sont évaluées en ciblant de multiples performances sociales. Un cadre conceptuel de planification, incluant la modélisation mathématique est proposé pour l’aide à la prise de décision dans des systèmes de distribution hyperconnectée. Partant des résultats obtenus par notre étude, nous avons démontré qu’un gain substantiel peut être obtenu en migrant vers la distribution hyperconnectée. Nous avons également démontré que l'ampleur du gain varie en fonction des caractéristiques des activités et des performances sociales ciblées. Puisque l'Internet physique est un sujet nouveau, le Chapitre 1 présente brièvement l’IP et hyper connectivité. Le Chapitre 2 discute les fondements, l'objectif et la méthodologie de la recherche. Les défis relevés au cours de cette recherche sont décrits et le type de contributions visés est mis en évidence. Le Chapitre 3 présente les modèles d'optimisation. Influencés par les caractéristiques des systèmes de distribution actuels et potentiels, trois modèles fondés sur le système de distribution sont développés. Chapitre 4 traite la caractérisation des échantillons d’affaires ainsi que la modélisation et le calibrage des paramètres employés dans les modèles. Les résultats de la recherche exploratoire sont présentés au Chapitre 5. Le Chapitre 6 décrit le cadre conceptuel de planification de la distribution hyperconnectée. Le chapitre 7 résume le contenu de la thèse et met en évidence les contributions principales. En outre, il identifie les limites de la recherche et les avenues potentielles de recherches futures.The Physical Internet (PI) is an initiative that identifies several symptoms of logistics systems unsustainability and inefficiency and tackles them by proposing a novel paradigm called Hyperconnected Logistics. Similar to the Digital Internet, which connects thousands of personal and local computer networks, PI will connect the fragmented logistics systems of today. The main purpose is to enhance the performance of logistics systems from economic, environmental and social perspectives. Focusing specifically on the distribution system, this thesis questions the order of magnitude of the performance gain by exploiting the PI-enabled hyperconnected distribution. It is also concerned by the characterization of the hyperconnected distribution planning. To address the first question, an exploratory research approach based on optimization modeling is applied; first, the current and prospective distribution systems are modeled. Then, a set of realistic business samples are created, and their economic and environmental performance by targeting multiple social performances are assessed. A conceptual planning framework is proposed to support the decision making in the hyperconnected distribution system. Based on the results obtained by our investigation, it can be argued that a substantial gain can be achieved by shifting toward Hyperconnected Distribution. It is also revealed that the magnitude of the gain varies by business characteristics and the targeted social performance. Since the Physical Internet is a novel topic, chapter 1 briefly introduces PI and Hyperconnected Logistics. Chapter 2 discusses the research foundations, goal and methodology. It also describes the challenges of conducting this research and highlights the type of contributions aimed for. Chapter 3 presents the optimization models including a core distribution network design modeling approach. Influenced by the characteristics of the current and prospective distribution systems, three distribution system-driven models are developed. Chapter 4 engages with the characterization of the business samples, the modeling and calibration of the parameter that are employed in the models. The exploratory investigation results are presented in Chapter 5. Chapter 6 describes the hyperconnected distribution planning framework. Chapter 7 summarizes the content of the thesis and highlights the main contributions. Moreover, it identifies the research limitations and potential future research avenues.

Full textAbstract:
Physical security systems are intended to prevent or mitigate potentially catastrophic
loss of property or life. Decisions regarding the selection of one system or
configuration of resources over another may be viewed as design decisions within a
risk theoretic setting. The problem of revealing a clear preference among design alternatives,
using only a partial or inexact delineation of event probabilities, is examined.
In this dissertation, an analytical framework for the assessment of the risk associated
with a physical security system is presented. Linear programming is used
to determine bounds on the expected utility of an alternative, and conditions for
the separation of preferences among alternatives are shown. If distinguishable preferences
do not exist, techniques to determine what information may help to separate
preferences are presented. The linear programming approach leads to identification
of vulnerabilities in a security system through an examination of the solution to the
dual problem.
Security of a hypothetical military forward operating base is considered as an
illustrative example. For two alternative security schemes, the uncertainty inherent in
the scenario is represented using probability assessments consisting of bounds on event
probabilities and exact probability assignments. Application of the framework reveals
no separation of preferences between the alternatives. Examination of the primal and dual solutions to the linear programming problems, however, reveals insights into
information which, if obtained, could lead to a separation of preferences as well as
information on vulnerabilities in one of the alternative security postures.

Full textAbstract:
The objectives of The Identification and Prevention of Dietary and Lifestyle Induced Health Effects in Children and Infants study (child sample) and the Kenya Adolescent Physical Activity study (adolescent sample) conducted in this thesis was firstly, to assess the impact of methodological and practical decisions such as the appropriate epoch length and cutpoints to use in accelerometry studies involving children and adolescents across the physical activity continuum and the reliability of these accelerometer outcomes in predicting habitual physical activity. Secondly, the performance of uniaxial ActiTrainer accelerometry with heart rate (HR) monitoring was compared to triaxial GT3X accelerometry against indirect calorimetry during structured activities in the predominantly active Kenyan adolescent cohort. Similarly, the performance of uniaxial ActiTrainer accelerometry with HR monitoring vs. triaxial 3DNX accelerometry was compared against DLW under free living conditions in both children and adolescent cohorts. Finally, the validated uniaxial ActiTrainer was used to assess the impact of physical activity and the environment on energy expenditure and indices of adiposity in the two cohorts. The main findings of the thesis were: (a) that 15 s epoch reports significantly higher engagement in physical activity compared to a 60 s epoch in both the children and adolescents cohorts (b) choice of cutpoints significantly affected classification of physical activity and sedentary behaviour in both cohorts (c) a minimum of 6 h for 7 - 9 days in the cohort involving children and a minimum of 6 h for 4 - 5 days in the adolescents were required to reliably measure physical activity (d) triaxial accelerometry reported better predictive validity compared to uniaxial accelerometry during structured activities. In addition, HR monitoring did not improve the predictive validity of either accelerometer during structured activities (e) during free living activities, however, uniaxial and triaxial accelerometry reported comparable predictive validity. The addition of HR monitoring improved the predictive validity of uniaxial accelerometry by approximately 4% in both cohorts (f) in both cohorts, total volume of physical activity and patterns (time engaged in light and moderate to vigorous physical activity) were significantly associated with energy expenditure (g) physical activity and sedentary behaviour were significantly related to indices of adiposity in both cohorts (h) the environment was a significant predictor of physical activity and indices of adiposity in the adolescents but not children. The findings of this thesis have important implications on strategies to standardise accelerometry field protocols and future studies on the validation of accelerometers and the association between physical activity, the environment and health.

Romero, Rodriguez Daniel. "Physical and Social Systems Resilience Assessment and Optimization." Scholar Commons, 2018. https://scholarcommons.usf.edu/etd/7359.
Full textAbstract:
Resilience has been measured using qualitative and quantitative metrics in engineering,economics, psychology, business, ecology, among others. This dissertation proposes a resilience metric that explicitly incorporates the intensity of the disruptive event to provide a more accurate estimation of system resilience. A comparative analysis between the proposed metric and average performance resilience metrics for linear and nonlinear loss and recovery functions suggests that the new metric enables a more objective assessment of resilience for disruptions with different intensities. Moreover, the proposed metric is independent of a control time parameter. This provides a more consistent resilience estimation for a given system and when comparing different systems.
The metric is evaluated in the study of community resilience during a pandemic influenza outbreak and the analysis of supply chain resilience. As a result, the model quantifies constant, increasing and decreasing resilience, enables a better understanding of system response capabilities in contrast with traditional average performance resilience metrics that always capture decreasing resilience levels when the disruptive events magnitude increases. In addition, resilience drivers are identified to enhance resilience against disruptive events.
Once resilience drivers have been found, then a multi-objective resource allocation model is proposed to improve resilience levels. Previous resilience optimization models have been developed mainly based on a single resilience metric. The existing bi-objective models typically maximize resilience while the recovery cost is minimized. Although the single metric approach improves system resilience some of their limitations are that the solution is highly dependent on the selected resilience index and generally few optimal points are found. To overcome the rigidity of a unique metric a bi-objective model is proposed to maximize two key resilience dimensions, the absorptive and restorative capacities. This approach has the potential to offer multiple non-dominated solutions increasing decision makers alternatives where the single metric solutions are included.

Full textAbstract:
Most pediatric orthopaedic interventions are intended to improve or preserve physical function, yet their outcomes have been assessed using primarily surrogate measures (e.g., radiographic indices) that may not accurately represent patients'function. Physical function may be more appropriately measured with activity-based scales, but these have been infrequently applied in surgical studies. The purpose of this study was to identify existing activity-based physical-function scales appropriate for pediatric orthopaedics, to present criteria useful for scale selection, and to discuss the special problems of measuring physical function in children. Twenty-one scales relevant to pediatric orthopaedics are described according to their target population, purpose, method of administration, content, and quality of standardization. These scales have been further classified according to a new taxonomy. The unique aspects of measuring physical function in children are discussed and include the effect of age and development, method of reporting, and question formats. Standardized measures of physical function based on physical-activity ability exist and should be used more frequently to assess pediatric orthopaedic interventions

Full textAbstract:
Health benefits are found to be associated with regular physical activity (PA), however, only a small percentage of young people are meeting the government physical activity recommendation guidelines. Therefore, there is a necessity to further understand the factors that may influence greater participation in physical activity. One essential influencing factor may be the level of mastery of motor abilities (MA) which children and adolescents need in order to participate in different physical activities. Therefore, this thesis was built on the hypothesis that children with better developed motor abilities may find it easier to be active and engage in more physical activity than those with less-developed motor abilities. This thesis provides three studies focusing on firstly, validating accelerometer counts against oxygen uptake (energy expenditure or EE) in 9 to 11 year old children performing a number of highly variable physical activities, similar to those undertaken in free-living conditions. Cut-off points for resting physical activity level, light physical activity level, moderate physical activity level and vigorous physical activity level were determined, which have been used to analyse PA data in studies 2 and 3. The second study was a cross-sectional design and third study was a longitudinal design. Both studies investigated the level of motor ability that 8 to 12 year old children possessed; secondly, they explored how anthropometric factors affected selected components of MA and thirdly, they determined whether MA components themselves and/or anthropometric measurements are useful predictors of physical activity levels. Results showed a strong correlation between the accelerometer counts and energy expenditure (as measured by oxygen consumption) of r = 0.86, and two different regression equations to predict EE from accelerometer counts were developed. Cut-off points of <61, 62 - 3435,3436 - 6100, and 2: 6101 were determined for resting, light, moderate and vigorous physical activity levels. The cross-sectional study showed that motor ability components were improved with increasing school year. Gender was the main predictor of most motor ability components; while body fat percentage (BF%) and age were secondary factors. The cross-sectional design does not allow the drawing of a causal relationship between the development of motor ability and physical activity levels. Thus, the longitudinal study illustrated that tracking motor ability and anthropometric data over time removed gender as a dominating factor in predicting the motor ability component as found in the cross-sectional study (Chapter 4). Changes in Standing Vertical Jump, Sit-up and Flamingo Balance Test were found to be factors that could affect change in physical activity levels. However, the small number of participants who met the criteria of physical activity intensity levels in this study mean that interpretations of results should be taken with caution. Further longitudinal research using a large group of children, motor ability component tests and more than one objective method to monitor physical activity levels are needed to clearly explore the relationship between these two parameters,

Full textAbstract:
Lack of motivation has been highlighted as a major cause of adverse patients outcomes during the rehabilitation process.Thanks to the evolution in the way video games are controlled, from totally passive to active situation, clinicians have had the idea of integrating video games into rehabilitation to increase adherence to treatments, especially during at-home exercises.Specially developed games, the Serious Games (SG), must be created to fulfill the needs and specificities of clinicians and patients.As the rehabilitation exercises are performed in the SG, it is easy to record the movements performed by the patients with the gaming hardware.The aim of this thesis was to determine if the gaming hardware, the Kinect sensor and the Wii Balance Board, can be used to: i) perform functional evaluation of the patients, ii) monitor motions performed by the patients during the rehabilitation exercises and iii) assess the severity of the disease based on the performance during the SG.In order to validate this new approach several validation processes were done: from the strict controlled environment gait laboratory to the clinics.The different developments and validation phases are presented in this thesis.Doctorat en Sciences biomédicales et pharmaceutiques (Médecine)

Full textAbstract:
Low levels of physical activity are correlated with negative health outcomes such as heart disease, diabetes, and certain types of cancer. This is concerning given the current rise in obesity and physical inactivity, especially in young children. Developing assessments that can readily identify variables related to unhealthy patterns of activity might be useful in informing interventions that aim to increase physical activity. The current study extended previous research in the functional analysis of physical activity by Hustyi, Normand, and Larson (2012) by evaluating the utility of a choice assessment procedure to identify participant preference to several common outdoor activity contexts, typically available during school recess. Together, the two assessments strategies were able to identify both healthy and less healthy patterns of responding in four preschool-age children. The information obtained from these assessments could be used to inform behavioral interventions that aim to increase physical activity in young children.

Full textAbstract:
Globally, availability of water of acceptable quality is under stress and only less than half of the predicted demand is likely to be addressed by improvements in water productivity and new water supply systems. In addition, climate change is having a significant impact on water resources and could cause catastrophic water related disasters. Water security is thus becoming a major pressing issue within the emerging global resource crisis. However, significant inconsistencies with the definition of water security have halted its use in practice, impeding the formation of a consensus on many water related issues. Water Security as a concept needs to contain and highlight several features including economic and other related risks. This thesis investigated the dual (economic-physical) nature of water security and introduced Economic Water Availability (EWA) as a term to complement its definition. Findings indicated that EWA dominates water withdrawal under conditions of severe physical water scarcity. They also demonstrated that there is a range where strong relationships between water related disasters and two selected economic factors, GNI per capita and GINI index, exist. These selected indices, which have been commonly accepted and well established, are advantageous in achieving social consensus on water security issues as well as providing adaptation solutions. Several desirable features of water security indices were also proposed including consideration of catastrophic events which are aggravated by climate change, simplicity ensuring effective communication, physical and economic variability, economic considerations and inequality. A simplified framework for water security assessment has been developed by adopting all those desirable features. The proposed framework is practical, simple and as it is based on research trend and requirements for interpreting current issues, it aims to allow policy makers to communicate these effectively to the general public. The findings of this study will also help many countries uncover critical areas in terms of water security and change their political priority.

Assessing a network's physical security is an essential step in securing its data. This document describes the design, implementation, and validation of PSATool, a prototype application for assessing the physical security of a network's intermediate distribution frames, or IDFs (a.k.a. "wiring closets"). PSATool was created to address a lack of tools for IDF assessment. It implements a checklist-based protocol for assessing compliance with 52 security requirements compiled from federal and international standards. This checklist can be extended according to organizational needs.
PSATool was validated by using it to assess physical security at 135 IDFs at East Tennessee State University. PSATool exposed 95 threats, hazards, and vulnerabilities in 82 IDFs. A control was recommended for each threat, hazard, and vulnerability discovered. The administrators of ETSU's network concluded that PSATool's results agreed with their informal sense of these IDFs' physical security, while providing documented support for improvements to IDF security.

Full textAbstract:
Background. The Association for Physical Education (afPE) recommends that during physical education lessons, students should be physically active for at least 50% of class time. Methods used to determine time spent in MVPA during PE classes should be sensitive enough to capture the sporadic bursts of activity typical of children. However, the extent to which students engage in physical activity is variable, and will be influenced by activity type, school settings, PE structures and gender. Aim. The main aim of this thesis was twofold; first to investigate if type of activity, genders and PE structures significantly influence on children and adolescents PA to meet PE recommendation; second to investigate the influence of natural intervention design in increasing children's PA during school morning break. Method. A series of four studies were conducted to assess children and adolescents PA using accelerometer (in four studies), direct observation (in two studies) and HR monitoring (in one study), with short epochs < 5-s. Results. Data from accelerometers and direct observation are highly comparable, but the validity of HR monitors in PE was questionable. Data from accelerometers and direct observation showed that children were not sufficiently physically active to meet the recommended 50% of PE time. Activity types and genders showed significant differences in children PA levels. Intervention design during break time significantly increased PA levels compared to structured PE and free play during lunch time for both genders.

Full textAbstract:
The achievement of predictable and long lasting adhesive restorations in posterior teeth have always been a major objective of studies in the context of materials and techniques development. The use of bulk fill composites could provide better outcomes, but it is important to assess their physico-mechanical properties, responsible for their clinical behavior. The purpose of the present study was to assess the mechanical and physical properties of bulk fill composites. The composites were divided into 2 groups according to their viscosity. For low viscosity composites, the present study assessed: Surefill SDR flow (SDR), X-tra Base (XB), Filtek Bulk Fill Flowable (FBF), and Filtek Z350XT Flow (Z3F- control); and for high viscosity composites: Tetric Evo Ceram Bulk Fill (TBF), X-tra Fil (XF), Filtek Bulk Fill (FBP), Admira Fusion x-tra (ADM) and Filtek Z350 XT (Z3XT- control). Composites were assessed through shrinkage stress test (using 12 and 24mm3 of composite in a custom device adapted in an Universal Testing Machine); volumetric shrinkage (using 64mm3 of composite placed on a Teflon mold and scanned in a micro computed tomography/CT); Youngs modulus (through a 3-point bending test device adapted in an Universal Testing Machine); microhardness and depth of cure tests (using longitudinal Knoop microhardness). All data was evaluated regarding their homogeneity using Shapiro-Wilk test. For polymerization stress, 3-way Variance Analysis (ANOVA) was used. Considering Volumetric Shrinkage, Youngs Modulus, Microhardness and Depth of Cure, one-way ANOVA was used. All ANOVA tests were followed by Tukeys test and 5% was adopted as significance level. Shrinkage stress test with 12mm3 showed SDR, TBF and XF generating the lowest stress after 300s, followed by other high viscosity composites (ADM, FBF, XB and FBP/Z3XT). The regular low viscosity composite (Z3F) generated the highest stress for all assessed times. Considering the same test, with 24mm3, after 300s, SDR, FBP and ADM generated similar stress, followed by TBF and XF. Low viscosity bulk fill composites generated lower stress than Z3F. Considering Youngs modulus, low viscosity composites (SDR, FBF, XB and Z3F) showed the lowest values, followed by ADM and TBF. The other high viscosity composites (Z3XT, FBP and XF) showed the highest values. For microhardness test, all low viscosity composites showed lower values (FBF being the lowest). For high viscosity composites, Z3XT showed the highest values, followed by XF, FBP/TBF and ADM. Assessing depth of cure, regular composites showed lower values when compared with bulk fill composites. All bulk fill composites showed adequate depth of cure over 4.5mm (microhardness 80% of initial reading). SDR and XB showed the highest depth of cure. All high viscosity bulk fill composites generated lower volumetric shrinkage than regular composites. All low viscosity bulk fill composites showed similar volumetric shrinkage when compared to the regular composites (Z3F and Z3XT). Bulk fill composites show characteristics that allow their use in larger increments (i.e. volumetric shrinkage and polymerization stress similar or lower when compared with regular composites). Nonetheless, the mechanical properties of bulk fill composites were widely variable, being important to individually assess each material previously to its clinical application.A obtenção de restaurações adesivas previsíveis e duradouras em dentes posteriores sempre foi objetivo de estudos na área de desenvolvimento de materiais e técnicas. O uso de resinas compostas do tipo bulk fill pode possibilitar melhores resultados, porém é importante o estudo de suas propriedades físico-mecânicas, responsáveis por seus comportamentos clínicos. O objetivo do presente estudo foi o de avaliar as propriedades físicas e mecânicas das resinas bulk fill. As resinas foram divididas em 2 grupos de acordo com sua viscosidade. Para resinas de baixa viscosidade, o presente estudo avaliou: Surefill SDR flow (SDR), X-tra Base (XB), Filtek Bulk Fill Flowable (FBF) e Filtek Z350XT Flow (Z3F-controle); e, para alta viscosidade: Tetric Evo Ceram Bulk Fill (TBF), X-tra Fil (XF), Filtek Bulk Fill (FBP), Admira Fusion x-tra (ADM) e Filtek Z350 XT (Z3XT-controle). As resinas foram avaliadas em relação à tensão de polimerização (utilizando 12 e 24mm3 de resina adaptadas em um dispositivo adaptado a uma máquina de testes universal); contração volumétrica (utilizando 64mm3 de resina composta inserida em um molde de Teflon e escaneada em um micro-tomógrafo/CT), modulo de Young (através de um dispositivo de flexão em 3 pontos adaptado a uma máquina de testes universal), microdureza e profundidade de polimerização (utilizando microdureza Knoop). Todos os resultados foram avaliados em relação à homogeneidade utilizando o teste de Shapiro-Wilk. Para avaliação da tensão de polimerização, foi empregada a Análise de Variância (ANOVA) a 3 critérios. Para as analyses de contração volumétrica, Módulo de Young, microdureza e profundidade de polimerizaçao, ANOVA a um critério foi empregada. Todas as Análises de Variância foram seguidas pelo teste de Tukey e 5% foi adotado como nível de significância. A tensão de polimerização com 12mm3 demonstrou que SDR, TBF e XF geraram valores significantemente mais baixos após 300s, seguidas por outras resinas de alta viscosidade (ADM, FBF, XB e FBP/Z3XT). A resina convencional de baixa viscosidade (Z3F) gerou valores de tensão significantemente mais elevados para todos os tempos avaliados. Considerando o mesmo teste, com 24mm3, após 300s, SDR, FBP e ADM geraram valores estatisticamente inferiores, seguidas por TBF e XF. As resinas bulk fill de baixa visocidade geraram menor tensão de polimerização que a Z3F. Considerando o modulo de Young, resinas de baixa viscosidade (SDR, FBF, XB e Z3F) apresentaram valores significantemente inferiores, seguidas por ADM e TBF. As outras resinas de alta viscosidade (Z3XT, FBP e XF) apresentaram valores significantemente mais elevados. Para o teste de microdureza, todas as resinas de baixa viscosidade apresentaram valores inferiores (FBF apresentou o menor). Para as resinas de alta viscosidade, Z3XT apresentou os valores mais elevados, seguida por XF, FBP/TBF e ADM. Para profundidade de polimerização, resinas compostas convencionais apresentaram valores signifixantemente mais baixos quando comparadas com resinas bulk fill. Todas as resinas bulk fill apresentaram profundidade de polimerização adequada até pelo menos 4,5mm (microdureza 80% da leitura inicial/superfície). SDR e XB apresentaram os valores mais altos de profundidade de polimerização. Todas as resinas bulk fill de alta viscosidade geraram menor contração volumétrica que resinas compostas convencionais. Todas as resinas bulk fill de baixa viscosidade apresentaram contração volumétrica similar às resinas convencionais (Z3F e Z3XT). Resinas compostas bulk fill apresentaram características que possibilitam sua indicação para serem empregadas em grandes incrementos (contração volumétrica e tensão de polimerização similar ou inferiores às resinas convencionais, além de maior profundidade de polimerização). No entanto, as propriedades mecânicas variaram grandemente entre as resinas estudadas sendo importante uma avaliação individual de cada material previamente ao seu uso clínico.

The purpose of this study was to develop and validate a psychometric instrument called the Ottawa Mental Skills Assessment Tool (OMSAT), which attempted to determine the relative importance of mental skills required to achieve levels of excellence in sport performance. A review of the literature of sport psychology experts Anshel, (1987); Mahoney, (1989); Mahoney, Gabriel & Perkins, (1987); Orlick (1980, 1986, 1992); Seiler, (1992) and Vealey, (1988) was completed and served as the basis for the creation of the OMSAT questionnaire. The questionnaire was initially comprised of 14 scales including a total of 113 questions. The 14 scales were further divided into five major areas: (1) Foundation Skills (commitment, belief); (2) Affective Skills (stress reactions, fear, relaxing, energizing); (3) Cognitive Skills (goal-setting, imagery, mental practice, focus, refocus); (4) Competition Skills (simulation, competition planning); and (5) Team dynamics. The OMSAT questionnaire was distributed to a sample of 486 subjects who were divided into three groups based on their gender, sport discipline and athletic level of achievement. Following statistical analyses (i.e., internal consistency, frequency item distribution) of every question, a new condensed version of the OMSAT was formulated. This new version was comprised of 71 questions within 12 scales. Results of the condensed version of the OMSAT demonstrated high levels of internal consistency (alpha levels above.78), and acceptable levels of test-retest reliability (r levels above.63). Mean score differences indicated that elite athletes scored higher than competitive athletes, who in turn, scored higher than recreational athletes in nearly all of the OMSAT scales. Overall, the OMSAT appears to provide a potentially useful assessment and diagnostic tool for both understanding, and potentially, counselling athletes of different ability levels.

Full textAbstract:
As physical therapists are becoming more involved with the pregnant population both in traditional patient care as well as in childbirth education, a better understanding of the influence of pregnancy on the pain system is needed. The purpose of this study was to determine if an endogenous analgesia system is present in pregnant humans as has been shown to be present in animals (Ginzler, 1980). Women's affective and intensity responses were measured during late pregnancy, labor and post-partum. Using a repeated measures design, fifteen women responded to thermal stimuli (43-52 degrees C) by marking a visual analogue scale. No significant difference was found to exist demonstrating that stages of pregnancy have no effect on subjects' responses to thermal stimuli.
Additional research has shown that levels of endorphins in the cerebrospinal fluid also do not change with stages of pregnancy (Steinbrook et al, 1982). This study provides a behavioral measurement of pain perception that supports the clinical finding that no endogenous analgesia is present in humans during stages of pregnancy. Lastly, by reviewing research examining levels of endorphins present in the plasma and cerebrospinal fluid during stages of pregnancy, this study also supports the growing body of knowledge which suggests that pain mediation by endorphins occurs centrally and not in the periphery.

Full textAbstract:
Physical Education (PE) includes the development of knowledge and positive attitudes toward physical activity. Regular physical activity participation during childhood and adolescence has many beneficial effects on health. The purpose of the study was (a) to describe student physical activity level, lesson context and teacher behavior, (b) to determine the relationships among physical activity, lesson context and teacher behavior, (c) to investigate the differences among these variables in public and private schools. Nineteen PE teachers from public and private schools in Ankara participated to the study. For data collection, 6th, 7th and 8th, (n=144) grade elementary school students were observed systematically by using SOFIT during 36 lessons. Results showed that students were spending little time in moderate to vigorous physical activity and they were generally standing or sitting in PE lesson. During the active time, they were generally practicing skill in both public and private schools. Teachers spent majority of lesson time on providing instruction for skill practice. However, teachers did not spend time on fitness knowledge and promotion of fitness in PE lessons. The findings of the study showed that there was a significant relationship between student activity level, lesson context and teacher behavior variables. PE teachers in public schools had higher scores of demonstration but teachers in private schools had higher scores of observation. In addition, there were no significant differences in lesson context variable between schools. Physical Education classes require active participation of students for skill and fitness development. However this study indicated that although students were practicing some forms of skills, there were not spending time on fitness development and fitness promotion during classes. Provision of in service training for teachers and revision in PE teachers&rsquoeducation curriculum might be needed to improve the health-related physical activity levels and knowledge of adults of future.

Full textAbstract:
The purpose of this study was to design, pilot, and evaluate three alternative
assessments that measured fourth and fifth grade student's understanding of
physical activity guidelines as contained in the Surgeon General's Report
(USDHHS, 1996). The alternative assessments were: 1. designing a booklet for a
peer named Homer, 2. creating a Video Tape Advertisement for students at
another school; and 3. coding the perceived intensity level for one minute intervals
at an active aerobic type station (Perceived Intensity Level Assessment Task).
Four research questions guided the evaluation of the assessment tasks. They were:
1. Do students who have been taught the physical activity guidelines score
differently on the alternative assessment than those who have not been taught the
guidelines? 2. Do content experts agree that scores can be used to describe what
students have learned (content validity)? 3. Do students find the assessment task
worthwhile, enjoyable, and meaningful? 4. Is the alternative assessment prototype
"feasible" for a teacher to administer in a regular physical education setting?
Student score results, student self-reflections, and student interview data were used
to evaluate the first and third research questions. Teacher interview data and
Content Expert validity score results were used to analyze the second and fourth
research questions.
Results from this study indicated that the Homer Booklet Assessment Task
discriminated between those students who were taught (experienced group) and
those who were not taught (inexperienced group). Furthermore, both the Content
Experts and the teacher found this assessment to have high content validity and
found it to be feasible to use in a regular physical education setting. Although the
students enjoyed the Homer Booklet Task they found it to be the least enjoyable of
the three assessment tasks. In contrast, students enjoyed the Video Tape
Advertisement Task best. Although this assessment task did discriminate between
those who were taught and not taught there were a couple of problems with this
assessment. The teacher and Content Experts found this task to have feasibility
problems and scores did not discriminate for style. Finally, the Perceived Intensity
Level Assessment Task did not discriminate between students who were taught
and not taught.Ph. D.

Full textAbstract:
With prevalence rates of obesity among children and adolescents steadily rising, childhood obesity and overweight has become a public health concern. Publically funded elementary schools are in a unique position to provide children with opportunities regarding the promotion of physical activity and healthy nutritional behaviors. Purpose: The purpose of this study was to conduct exploratory research to investigate the dietary habits of elementary school students enrolled in four Hillsborough County Out-of-School Time (HOST) care programs. Methods: The study utilized a quantitative, non-experimental study design. The instruments that were used in this research included a new questionnaire that was titled “All about You Yesterday”. This paper questionnaire was a combination of questions from the Physical Questionnaire for Older Children, Youth Risk Behavior Survey, and Day in The Life Of Questionnaire. The questionnaire gathered information about what the students had eaten the day before. It also allowed for collection of students’ gender, age, and grade level, physical activity levels, and the amount of time they spent being sedentary. Dietary data collected from the questionnaire was inputted into the ASA-24-Kids program for calculating Healthy Eating Index scores. Scores were examined to categorize the children’s diets as: poor, needs improvement, and good. This data was plotted into SAS to determine if there were patterns. The relationships between dietary and demographic factors were analyzed. A logistic regression model was used to test the association between dietary scores and amount of physical activity. Results: A total of 91 students participated in this study. The average score was categorized as needs improvement, as were the majority of the students’ diets. The findings showed a pattern that diets improved from third to fourth grade and declined in fifth grade. More males had diets that were categorized as needs improvement rather than poor, and site C had the most students with diet in the needs improvement category. However, none of the covariates were significant. The models used to test the association between the HEI scores and the amount of physical activity produced large p- values (> 0.05), which indicates weak evidence against the null hypothesis that states that there is no association. The same was true for the association between sedentary levels and the HEI categories. Conclusions: The study showed that, regardless of having the opportunity to eat nutritious meals, a great number of after-school children had diets that were categorized as poor. Findings also showed that there was no association between diet and the amount of physical activity that the after-school children participated in; nor did the diets have an association with the sedentary levels reported. Recommendations: In an effort to improve the diets of elementary school children, schools should encourage their students to try fruits and vegetables that are being offered through taste tests. If the meals that are offered during the taste tests are enjoyed then they should be offered as part of the school’s lunch or snack. After school programs should also offer these taste tests and include short nutritional lessons into their programs where children are also given the opportunity to cook and eat healthy snacks.

Childhood obesity is increasingly present in schools and to be, in most cases, the place where children spend most of their day, can create an environment for prevention and intervention measures, with nutrition education programs and activities Physical properties. In this sense, the objective of the study is to make a validation and a cross-cultural adaptation of the instrument Go Nutrition Physical Activity Self Assessment for Child Care. This self-assessment tool was developed to assess the school context on nutritional status and physical activities with children from birth to five years of age. The stages of the validation process followed the recommendations proposed by Gjersing, Caplehorn and Clausen (2010): conceptual research, translation and re-translation, expert committee, pre-test, review, application with target audience and statistical analysis. According to the results, in the translation and re-translation phase, there was reliability in the final language with that of experts analyzed regarding Clarity of language, practical and theoretical relevance and showed that the items analyzed have good understanding and the questions with results below 75% were reformulated with the aim of improving language clarity. In the pre-test, language clarity was good and could go to the audience application. After this application, Cronbach's alpha showed satisfactory values for the items analyzed. Therefore, the conclusion is that it is possible to provide a comprehensive and reliable instrument to evaluate children's physical activity and nutrition practice in the context of Brazilian early childhood education.A obesidade infantil está cada vez mais presente nas escolas e, na maioria dos casos, o lugar onde as crianças passam a maior parte do dia, pode criar um ambiente de prevenção e medidas de intervenção, com programas e atividades de educação nutricional Propriedades físicas. Nesse sentido, o objetivo do estudo é fazer uma validação e uma adaptação transcultural do instrumento Go Nutrition Physical Activity Self Assessment for Child Care. Esta ferramenta de auto-avaliação foi desenvolvida para avaliar o contexto escolar sobre o estado nutricional e atividades físicas com crianças desde o nascimento até os cinco anos de idade. As etapas do processo de validação seguiram as recomendações propostas por Gjersing, Caplehorn e Clausen (2010): pesquisa conceitual, tradução e re-tradução, comitê de especialistas, pré-teste, revisão, aplicação com público-alvo e análise estatística. De acordo com os resultados, na fase de tradução e re-tradução, houve confiabilidade na linguagem final com a de especialistas analisados em relação à Claridade de linguagem, relevância prática e teórica e mostrou que os itens analisados têm boa compreensão e as questões com resultados abaixo 75% foram reformulados com o objetivo de melhorar a clareza linguística. No pré-teste, a clareza do idioma era boa e poderia ir para a aplicação do público. Após essa aplicação, o alfa de Cronbach mostrou valores satisfatórios para os itens analisados. Portanto, a conclusão é que é possível fornecer um instrumento abrangente e confiável para avaliar a atividade física e a prática de nutrição das crianças no contexto da educação infantil brasileira.

Positron Emission Tomography has experienced several advances-in the last decade. This thesis assesses the recent developments in PET scanners: New, fast scintillators, higher resolution detectors, fully 3D imaging and increased sensitivity, iterative reconstruction algorithms with implementation of point spread function modelling and time-of- flight. The physical performance characteristics of three multi-ring and one panel based configuration were quantified using phantom experiments. The clinical impact of increased sensitivity was explored. Figures of merit to assess image quality were established and a method to optimise reconstruction algorithms for signal-to-noise was developed and applied. The improvements of implementing point spread function modelling into image reconstruction were investigated and quantified. The implementation of time-of- flight in addition to point-spread-function modelling was explored in substantial detail and compared. Experimental results were obtained and the clinical impact of time-of- flight was assessed. In a final investigation, the panel based PET scanner design was successfully applied in veterinary medicine.

Pulmonary patients attending outpatient rehabilitation experience an enhanced ability for physical activity. The current study assessed and characterized domestic physical activity levels of new and maintenance patients to 1) compare physical activity levels of pulmonary patients on rehabilitation and non-rehabilitation days, 2) to identify factors that may contribute to low physical activity levels and 3) to compare step count levels between 2 activity monitors.Eighteen patients (age, 66.2 ± 8.8 y; FEV1, 52.1 ± 11.8%) participating in pulmonary rehabilitation wore an accelerometer and pedometer for 7 consecutive days. Patients new to pulmonary rehabilitation and maintenance patients participated in the study. Upon returning the monitors, patients returned a log sheet with the times monitors were put on and taken off each morning and night.The participants who completed the one week assessment had an average step count of 3,800 ± 1,651 steps/day, with a significant difference (p < .05) between rehabilitation days (5,468 ± 2,810 steps/day) and non-rehabilitation days (2,874 ± 1,490 steps/day). The number of minutes/day spent in moderate walking activities was also significant (p < .05) between rehabilitation (10.9 ± 16.0 minutes/day) and non-rehabilitation days (3.1 ± 5.8 minutes/day). Male waist circumference and occupational status were significantly correlated with low physical activity levels. The pedometer and accelerometer step count values were not significantly different from each other.Patients participating in pulmonary rehabilitation have significantly different activity levels between rehabilitation and non-rehabilitation days. To increase activity benefits, patients with COPD should increase activity levels on rehabilitation and non-rehabilitation days. Special consideration should be taken to help patients increase physical activity levels on non-rehabilitation days.(key words: chronic obstructive pulmonary disease, pedometer, accelerometer, pulmonary rehabilitation.School of Physical Education, Sport, and Exercise Science

Thesis (MA)--Stellenbosch University, 2000.ENGLISH ABSTRACT: This research investigates the indicators, different role players and the assessment process of intentional physical injuries to children who are hospitalized. The basic premise for this research is the importance of professionals working with children in acquiring skills and knowledge on handling physically abused children. Physical abuse affects and requires the involvement of the entire family of the physically abused child. It is therefore necessary to consider the physically abused child as a part of the larger family system, and not assessed or treated in isolation. The purpose of this research is to broaden the theoretical knowledge of professionals working with children, and specifically social workers, in identifying and assessing physically abused children. This research report includes an investigation of risk factors, consequences and the adjustment process of physically abused children. Knowledge of these indicators of physical abuse will increase the awareness and the ability of the social worker or other professional to identify the injury as intentional. The assessment process by the multi-professional team in the hospital is also examined, focusing on the central role of the social worker in managing cases of physically abused children. The phases of the assessment process, the role of each team member, the various techniques applied as well as factors influencing assessment are described. The empirical research involved the use of both qualitative and quantitative methods in order to explore the theoretical part of the research. This section can be divided into three phases. The first phase included setting up a profile, over a period of four months, of physically abused children under the age of five, who were admitted to the hospital and their families (N = 24). Of this sample, the characteristics and circumstances of four parents/perpetrators (n = 4) were investigated in the form of interviews, which formed part of the second phase of the empirical research. The third phase included conducting a survey with the social workers (n = 5) that assessed physically abused children in the hospital. This was done III the form of questionnaires, which included closed and open-ended questions. The findings and responses of the respondents were analyzed and compared with the findings from previous studies undertaken by various authors. The findings of this research can be used as guidelines for professionals in general who work with children, and more specifically social workers in a hospital that assess children presenting with intentional physical injuries.
AFRIKAANSE OPSOMMING: Hierdie navorsing ondersoek die aanduidende faktore, die rolspelers en die asseseringsproses van fisies mishandelde kinders wat gehospitaliseer word. Die uitgangspunt is die noodsaaklikheid van professionele persone wat met kinders werk, en veral maatskaplike werkers, om kennis en vaardighede te hê, ten einde kinders wat fisies mishandel is te kan hanteer. Omdat die hele gesin van die mishandelde kind geaffekteer word en betrokke is, is dit belangrik om die fisies mishandelde kind nie in isolasie, maar as deel van die familie sisteem te kan benader. Die navorsingsondersoek het ten doel om die teoretiese kennis basis van professionele persone wat met kinders werk, en spesifiek maatskaplike werkers, oor die identifisering en assesering van fisies mishandelde kinders uit te brei. Ten einde maatskaplike werkers se kennis van die probleem onders aandag uit te bou, vervat die navorsingsverslag 'n bespreking van die risiko faktore, gevolge en aanpassingsproses van die fisies mishandelde kind. Kennis van hierdie aanduiders sal die bewusdheid asook die vermoë van professionele persone om die fisiese mishandeling te identifiseer, verhoog. Die asseseringsproses deur die multiprofessionele span in die hospitaal word ook ondersoek, met fokus op die sentrale rol van die maatskaplike werker in die hantering van fisies mishandelde kinders. Die fases van die asseseringsproses, die rol van elke spanlid, verskeie tegnieke en faktore wat assesering beïnvloed, word bespreek. Die teoretiese doel van die verslag word uitgebrei in die empiriese ondersoek, deur 'n bespreking van die bevindinge wat deur veskeie metodes verkry is. Kwalitatiewe asook kwantitatiewe metodes is benut tydens die drie fases van die empiriese ondersoek. Die eerste fase was die opstel van 'n profiel wat oor 'n tydperk van vier maande geneem is, van fisies mishandelde kinders wat toegelaat is in die hospitaal en hul gesinne (N = 24). Vanuit hierdie streekproef, is die eienskappe en omstandighede van vier ouers/oortreders (n = 4) ondersoek deur middel van onderhoude, wat die tweede fase van die ondersoek bevat. Die derde fase was om 'n opname te doen met die maatskaplike werkers (n = 5) wat die fisies mishandelde kinders in die hospitaal asseseer. Die bevindinge en response van die respondente is geanaliseer en vergelyk met die bevindinge van vorige studies wat deur verskeie outeurs onderneem is. Die bevindinge van hierdie navorsing kan as 'n riglyn gebruik word deur professionele persone wat oor die algemeen met kinders werk, en meer spesifiek maatskaplike werkers wat fisies mishandelde kinders in 'n hospitaal asseseer.

In 2000, the U.S. Census Bureau reported that Latinos represented 12.6% of the total population in the United States. It is projected that by 2010 Latinos will account for 15.5% of the population (1,2). Latinos account for 32% of the population in Texas, and specifically in Corpus Christi, Latinos represent 54% of the population (3). The purpose of this study was to compare reported versus actual physical activity among limited resource Latina mothers. This study also aimed to explore the validity of the existing Behavioral Risk Factor Surveillance System (BRFSS) and Seven-Day Physical Activity Recall (PAR) physical activity assessment tools.
Fifty-five Latina mothers from a Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) clinic in Corpus Christi, Texas were recruited to participate in this study. Data were collected through a combined (BRFSS and PAR) physical activity questionnaire as well as through step counts using pedometers. BRFSS and PAR reported significantly different levels of moderate physical activity (p=0.0312) using Chi Square tests when appropriate. The response rate in PAR for all levels of activity intensity was higher than BRFSS. There were significant trends between the number of steps reported and BRFSS and PAR moderate physical activity. Further, the majority of subjects who averaged greater than 5,000 steps per day did not perceive themselves to be moderately active in either BRFSS or PAR. These findings question the validity of these physical activity assessment tools with this population.Master of Science

Full textAbstract:
PE lessons are a unique context to address the declining levels of physical activity in the UK, offering the opportunity for students to achieve age appropriate physical activity recommendations. Therefore, it is imperative that researchers and practitioners understand variables that underpin students motivational processes in PE lessons. Psychological resilience refers to the idea that some individuals are able to positively adapt to the stressors they encounter. Conceptual theorisers of resilience propose that the concept comprises three constructs: stressors, positive adaptation, and protective factors. The purpose of the thesis is to focus on the first construct of stressors: which may be major life events, or the minor and cumulative demands of everyday life. Specifically, the current thesis aims to develop a measure of stressors in the context of PE lessons within the wider framework of resilience. The thesis is split into five chapters. The first chapter overviews the importance of facilitating motivation and engagement in PE lessons, and introduces the concept of resilience to stressors. Chapter two is split into three parts and comprises three reviews: the first provides an overview of the definitions, concepts, and theoretical models of academic resilience; the second is a systematic review of the approaches to measuring academic resilience and; the third presents a narrative review of daily stressors experienced by adolescents. Chapter three presents the first two studies of this programme of research. Study one is a qualitative exploration of the common stressors experienced by secondary school students during their PE lessons. Underpinned by the concept of resilience, study two explores the protective factors students utilise to facilitate their positive adaptation to these everyday stressors. Drawing on the reviews presented in chapter two, and the qualitative exploration of stressors in PE, chapter four presents a series of studies describing the development of the PE Experiences Questionnaire (PEEQ). Specifically, study three explores the content validity of a pool of items designed to reflect common stressors in PE lessons. Study four examines the factorial structure of the PEEQ using exploratory factor analysis, and study five tests the factorial structure of the PEEQ using confirmatory factor analysis. Study six tests the factorial structure on an independent sample, examines whether it is invariant across gender, and tests the relationship between the PEEQ and related educational constructs. Overall, the current programme of research has advanced the field of educational psychology by providing greater understanding of the potential stressors experienced during PE lessons, and the dynamic processes by which students respond.

Background
There are more than 300,000 persons in the U.S. living with transfemoral amputation (TFA). Persons with TFA use a knee prosthesis for gait and mobility. Presently, the C-Leg microprocessor knee prosthesis is the standard of care. C-Leg has significantly improved safety and cost efficacy and has created modest gains in gait efficiency. Recently, a new prosthesis has introduced a new sensor array and processor that reportedly improves knee motion, stair function and standing stability. Early claims of the reported functional benefits of the new Genium knee (formerly X2) have not been validated in a rigorous clinical trial. Therefore, the purpose of this project was to determine if the Genium knee improves safety, function and quality of life compared to the current standard of care (C-Leg).
Methods
The study is a randomized AB crossover with a control group. Subjects must have used (and still be using) a C-Leg for a minimum of 1yr prior to enrollment. Inclusion criteria beyond this are unilateral transfemoral or knee disarticulation amputation for any etiology, community level ambulation (Medicare level 3 or above), independent ambulation and ability to independently provide written, informed consent. Once enrolled subjects utilize their same socket but receive a study foot (Trias or Axtion). Subjects are randomly assigned to either stay with their C-Leg or be fit with a Genium knee. Subjects accommodate and test (A phase) then crossover to the other knee condition and repeat the testing (B phase). A follow up phase of the study beyond the B phase is ongoing to study longer term preference. For AB assessment, three domains were assessed: Safety, function and quality of life. For safety, the PEQ-A survey of stumbles and falls, posturography (Biodex SD limits of stability and postural stability tests), 4 square step test and 2 minute ramp stand test were completed. For function, a series of timed walking tests, the amputee mobility predictor, kinematic gait assessment and physical functional performance-10 tests were conducted. For quality of life, the socioemotional and situational satisfaction domains of the population specific and validated PEQ (prosthesis evaluation questionnaire) were completed.
Results
Safety: Posturographic assessment revealed impairment between transfemoral amputees and non-amputees. Stumbles and semi-controlled falls decreased with Genium but were not significantly different. Four square step testing was significantly (p 0.05) improved from 12.2s(3.3) to 11.1s(3.4) for the C-Leg and Genium respectively.
Function: Kinematic asymmetry was minimally different between knee conditions. The AMP mean(SD) scores while subjects used C-Leg was 40.8(3.6; 33-45) and 43.3(2.6) [p<0.001]. PFP scores (cumulative), upper body function and endurance scores were improved with Genium compared with C-Leg at 9.1%(p=0.03), 8.7%(0.01) and 10.3%(0.04) respectively.
Quality of Life: For quality of life, situational satisfaction favored Genium (p<0.001) which included subject's satisfaction with gait, training and quality of life in general.
Conclusion
C-Leg and Genium promote static weight bearing beyond asymmetric values reported in the literature. In terms of limits of stability, TFA's are clearly impaired, primarily over the amputated side posteriorly however the Genium seems to enable posterior compensations that coincide with multi-directional stepping improvements. Anteriorly, the C-Leg's toe triggering requirements seem to improve limits of stability but come at the cost of discomfort on ramp ascent. With regard to safety, it seems that both knee systems represent good options for the community ambulating TFA.
The largest improvements with Genium were in the activities of daily living assessment; predominantly balance and upper body function. It seems that the combination of multi-direction stepping with starts and stops and stair ascent are key areas of improvement. In conclusion, the sensor array in the Genium knee prosthesis promotes improved function in activities of daily living. Specifically improved in this context were balance, endurance, multi-directional stepping, stair ascent and upper limb function in highly active transfemoral amputees.

An intervention designed to develop mental imagery skills was implemented in a primary school setting for children from grades 1 to 6. Children were separated into control and experimental groups and pre- and post-test measures were taken to determine the effects of the intervention on mental imagery ability. A self-report inventory, Kids Imagery Scale (KIS), and objective performance task, Ski Run Assessment Tool (Ski Run), were designed and administered to measure these effects. In addition, qualitative data collection was obtained from logging procedures during the intervention phase and questionnaires in post-test. Results showed significant improvement from experimental group children on the Ski Run scores but not on KIS scores. Qualitative analysis showed some indication of improved imagery ability of experimental group children. A secondary focus of the study examined the effects of the intervention on the mood and self-esteem of the children. The KISS Self-esteem Scale was designed and administered to measure change between groups and within groups. Though no significant improvement was realized, a significant correlation between self-esteem scores and KIS scores were found.

Full textAbstract:
Since its inception, the Outcomes-Based Education (OBE) curriculum in South Africa has caused much confusion and frustration among teachers, especially with regard to the implementation of Outcomes- Based Assessment (OBA). From the onset of the implementation of OBE in South Africa, teachers were confronted with unfamiliar challenges with regard to teaching, learning and assessment. Most teachers experienced these challenges as very stressful, because they were inadequately prepared for the didactical paradigm shift. This resulted in a general degree of negativity and resistance towards OBE amongst teachers. In particular, there seemed to be much confusion and frustration about the workload and administrative burden that OBA imposed on teachers.
In the light of the afore-mentioned, the researcher wished to determine how the teachers from the North- West Province experience the OBA of Physical Sciences in the Further Education and Training (FET) Band.
In order to achieve the aim and objectives of the research, a literature study as well as an empirical investigation was undertaken. The literature study focused on OBA, OBE, and the National Policy Document on the teaching, learning and assessment of Physical Sciences in the FET Band.
For the purposes of the empirical investigation, quantitative and qualitative data were collected by means of a questionnaire that was distributed among a sample of teachers who taught Physical Sciences in the FET Band schools in the North-West Province. The data were quantitatively and qualitatively analyzed and on the basis of the findings the following conclusions were drawn:
• Although most participants indicated that they received training in OBA and were in possession of the relevant National Curriculum Statement (NCS) documents, some of their responses indicated a lack of practical implementation skills. It also transpired that some of the participants experienced a lack of resources and inadequate support from subject advisors in implementing OBA.
• Participants experienced the following obstacles with regard to the assessment of Physical Sciences in the FET Band:
- inadequate training to conduct practical work;
- a complicated and confusing NCS document that does not contain clear guidelines;
- an overloaded curriculum; and
- limited resources, time constraints, overcrowded classrooms and an overloaded curriculum make practical work and experimentation very difficult.
On the basis of the findings emanating from the research, a model for the implementation of OBA of Physical Sciences in the FET Band was proposed to close the gap between the theory and assessment practice.Thesis (PhD (Natural Science Education))--North-West University, Potchefstroom Campus, 2013.
