Abstract:

Research has clearly shown that all individuals will benefit from regular physical activity. Unfortunately, young adults including college and university students are not physically active on a regular basis worldwide. In the developing world particularly in Sub- Saharan Africa, physical inactivity along with tobacco use, poor diet and nutrition are increasingly parts of today&rsquo
s lifestyle. Physical activity declines with age and the most important decline appear to be during the transition period from high school to university and during university years. The aim of this study was to assess the level of physical activity, to investigate the perceived constraints to physical activity and to determine whether socio-demographic characteristic have an influence on participation in physical activity and perceived constraints to physical activity among paramedical institutions students in Uganda. A cross-sectional study with descriptive quantitative design was conducted. Four hundred (400) paramedical institution students were selected using a stratified random sampling technique. A self-administered questionnaire adopted from the literature was used to collect the data. A response rate of 90% was obtained. Descriptive and inferential statistics using the statistical package for social sciences were used to analyze the data. The relationships and associations between different variables were determined by carrying out significant tests using chi-square tests. Alpha level was set at 0.05. The mean age of the sample was 22.44 years (SD = 2.03). Males constituted 73.9% and females constituted 26.1% of the sample. Students from eight (8) health professional courses participated in the study. Over half (59%) of participants were classified as physically active and 41% were classified as inactive or sedentary. For male participants, lack of the right equipment to exercise and wanting to do other things in their free time were perceived as the major constraints to physical activity. For female participants, lack of motivation and tiredness after exercise were perceived as the major constraints to physical activity. The findings of this study demonstrate that there is an influence of socio-demographic characteristics such as gender, year of the study and different departments/schools on participation in physical activity and perceived constraints to physical activity. They also indicate the need of health promotion intervention aiming at promoting physical activity among paramedical institution students in Uganda.

Discrete models of physical phenomena are an attractive alternative to continuous models such as partial differential equations. In discrete models, such as cellular automata, space is treated as having finitely many locations per unit volume. Physical processes are modelled by rules that typically depend on a small number of nearby locations. Such models have the feature that they depend critically on a regular (crystalline) lattice, as well as the global synchronization of all sites. We might well ask, on the grounds of minimalism, whether the global synchronization and crystalline lattice arc inherent in any discrete formulation. Is it possible to do without these conditions and still model physics? Or are they somehow fundamental? We will answer this question by presenting a class of models that are "extremely local" in the sense that the update rule does not depend on synchronization with other sites, or on detailed knowledge of the lattice geometry. All interactions involve only a single pair of sites. The models have the further advantage that they exactly conserve the analog of quantities such as momentum and energy which are conserved in physics. A framework for simulating the asynchronous, parallel model with irregular geometry on a sequential computer will be presented. Evidence will be given that the models agree well qualitatively and quantitatively with continuous differential equations. We will draw parallels between the various kinds of physical models and various computing architectures, and show that the class of models presented corresponds to a new parallel computing architecture known as an amorphous computer.

Abstract:

The following study examined the effects of physical activity against university students’ self-esteem levels in a medium sized city in Sweden. The paper was demarcated to investigate whether sport students differed from social program students on their level of self-esteem due to the amount of physical activity performed. We even took the variable of gender in account for examining the differences. The results showed that the group of sport students did in fact differ from the social program group on self-esteem, in terms of high and moderate physical activity, but not for low physical activity. The same outcome applied to the amount of physical activity performed only. When analyzing the gender differences, the results showed females in favor for having higher self-esteem levels than males across all three conditions of physical activity. Females also tended to perform high and moderate physical activity in a greater sense than males, while low activity had no significant difference. A conclusion was reached and we answered the research question that sport students did in fact have higher self-esteem levels and performed a higher amount of physical activity than social program students. However the differences was not noticeable large between the groups, which could be explained by other environmental and individual factors allowing this paper for further research within the topic and population of university students.
Följande studie har undersökt effekten av fysisk aktivitet mot universitetsstudenters självkänsla i en medelstor stad i Sverige. Arbetet är avgränsat till att undersöka huruvida sport studenter skiljer sig från sociala-programstudenter i nivåer av självkänsla beroende på deras fysiska aktivitet. Vi tog även hänsyn till könsvariabeln vid undersökning av variablerna. Resultatet visade att gruppen av sport studenter skiljde sig från de sociala-programstudenterna i deras självkänslenivåer i termer av hög och måttlig fysisk aktivitet, men ej för lätt fysisk aktivitet. Samma utfall gällde vid mätning av enbart utförd fysisk aktivitet. Vid analys av könsskillnaderna visade resultatet att kvinnor hade högre självkänsla utifrån fysisk aktivitet under alla tre nivåer än män. Kvinnor tenderade även att utföra hög och måttlig fysisk aktivitet i större utsträkning än män, medan lätt fysisk aktivitet inte visade upp någon skillnad. Ett slutsats nåddes där frågeställningen besvarades i form av att sport studenter hade högre självkänsla utifrån hur mycket fysisk aktivitet de utförde än sociala-programstudenter. Skillnaderna var emellertid inte märkbart stora mellan grupperna vilket kan antyda på andra individuella och omvärdsliga faktorer som påverkar utfallet. Detta möjliggör för fortsatt forskning inom området och framförallt inom populationen av universitetsstudenter.

Abstract:

The thesis will consist of five main chapters. In Chapter 1 a general description of random lattices and their geometrical properties will be given as well as a discussion of the formulation of random lattice field theory. The details of the construction of random lattices will be given in an appendix. In Chapter 2 there will be a discussion of the results of a simulation of the XY-model on a two dimensional random lattice. This simulation was carried out with the intention of comparing the behaviour of the XY-model on regular and random lattices. Chapter 3 will contain the results of a simulation of percolation models on random lattices using the technique of invasion percolation. In Chapter 4 there will be a proof that the problem of continuum percolation of disks can be formulated as a particular correlated bond percolation problem on a two dimensional random lattice. A simulation of continuum percolation based on the result of this proof will be described. The final chapter, Chapter 5, will be about diffusion in invasion percolation clusters.

Abstract:

The purpose of this study was to investigate to what extent university students are regularly physically active, what motives and barriers they perceive towards exercise and the relationship between motivational profile, self-efficacy and exercise behaviors. A questionnaire including the instruments Physical Activity Stages of Change, BARSE, BREQ-2 and Exercise Adherence Questionnaire was distributed at a university in southern Sweden. The respondents (n = 251) were Men (n = 104) and Women (n = 147). For analysis and processing of the gathered data SPSS was used with One-Way ANOVA, Pearson's r and Regression Analysis. The study showed that 70 percent of the students were regularly physically active. The most common motives for exercise were to improve health and increase physical strength whilst the most frequent barriers were lack of motivation and lack of energy/fatigue. The results also revealed positive correlations between identified regulation, intrinsic regulation, barrier self-efficacy and physical activity.

Master of Landscape Architecture
Department of Landscape Architecture/Regional and Community Planning

A significant decline of mental and physical health exists within college students today (ACHA, 2014; Gallagher, 2006). Recently, to promote mental health, restorative landscapes have emerged as a trend in healthcare environments by formalizing the healing properties of nature within a designed environment. Humans have been shown to undergo a measurable relief of stress, improved attention, and an improved overall sense of well-being when exposed to a restorative landscape setting. Opportunities exist for university campuses to more advantageously employ the mental health benefits of restorative landscapes. Furthermore, to address physical health, the university campus holds unique opportunities to increase students’ physical activity through promotion of active lifestyles using active modes of transportation. Campus streets, based on their lack of affordances to promote mental and physical health as well as their inherent connectivity to key campus buildings and spaces are investigated as a site for a designed solution. A recent trend of campus street conversions to pedestrian malls is identified and explored as a tool to facilitate creation of a restorative and active campus. The project, based in two fundamental research questions, investigates how campus street design can improve the collective mental health of college students, and how campus street design can promote physical health. Literature review analysis reveals theories and principles of restorative landscape and campus design. The project unites these findings with case study analysis to form a framework to facilitate the design of restorative environments within a university campus. Pragmatic evidence of built environment interventions has been synthesized from literature review and case study analysis into an additional framework to increase physical activity through active transportation. Kansas State University’s campus has been identified as a suitable case for a design proposal. Planning and design decisions at three nested scales are made to illustrate how the frameworks may be applied to reclaim a campus street as an active and restorative “garden street.” In the context of declining mental and physical health among college students, the synthesis of principles related to restorative landscape design and active transportation presents a valuable structure to mitigate declining mental and physical health of students.

Hill, Shannon Elizabeth. "Physical Models of Amyloid Fibril Assembly." Scholar Commons, 2011. http://scholarcommons.usf.edu/etd/3149.

Full text

Abstract:

Formation of large fibers and plaques by amyloid proteins is recognized as the molecular hallmark of an increasing number of human disorders, including Parkinson's disease, Alzheimer's disease and even type II diabetes. The broader objective of my research is to unravel the basic mechanisms that initiate and regulate fibril formation by amyloidogenic proteins. This objective is significant because even basic aspects of how fibril formation proceeds from a soluble, monomeric protein to an insoluble amyloid fibril remain much debated. Furthermore, there is increasingly strong evidence suggesting that intermediates of the aggregation process, with properties distinct from those of mature fibrils, are the aggregate species most toxic to human tissues. Combining non-intrusive optical techniques (dynamic light scattering) to characterize the nucleation and growth kinetics of aggregation intermediates with high-resolution imaging (atomic force microscopy) to characterize aggregate morphologies and their physical dimensions, we have investigated the self-assembly process of two distinctly different amyloidogenic proteins - hen egg white lysozyme and human recombinant tau. Initially, we used hen egg white lysozyme to characterize the kinetics and morphology of various intermediates emerging along a fixed assembly pathway. We further investigated whether and how the fibril assembly process for lysozyme changed as function of salt concentration. These experiments revealed that lysozyme displays three distinct types of aggregation behavior at different ionic strengths: monomeric fibril assembly, oligomeric fibril assembly, and amorphous precipitation. We followed these observations by exploring whether and how net intermolecular interactions among lysozyme monomers and the intramolecular conformation of lysozyme affect these transitions in the assembly process. We found that the prevailing intermolecular interactions played dominant roles in regulating fibril assembly pathways, suggesting that protein interactions hold critical clues on how to control amyloid fibril assembly. Using the same experimental approaches, we investigated the role of heat shock proteins as regulators of tau fibril assembly. The native function of human tau is to stabilize the microtubules in the axonal processes of neurons. The accumulation of aberrant tau into neurofibrillar tangles is diagnostic of many neurodegenerative diseases, including Alzheimer's disease, frontotemporal dementia, and Pick's disease. A significant body of research indicates that phosphorylation, oxidation, and ubiquitination of human tau can impair its affinity for microtubules and trigger self-assembly of hyperphosphorylated tau into these neurofibrillar tangles. Cells possess a large network of regulatory proteins called chaperones which are responsible for the proper folding and "disposal" of proteins, such as misfolded tau. We therefore investigated the role of different chaperones on in vitro fibril assembly of tau. We show that the small chaperone Hsp27, regardless of phosphorylation, is capable of inhibiting tau fibril growth in vitro. In contrast, dynamic phosphorylation and dephosphorylation of Hsp27 in vivo are necessary mechanisms for tau clearance and inhibition. By defining these differences in tau aggregation under in vitro vs. in vivo conditions, we hope to gain better understanding on how the chaperone network interacts with tau and how to target various chaperones for therapeutic interventions.

Abstract:

Water is a fundamental part of life as we know it, and by that also a fundamental for biology, chemistry, and parts of physics. Understanding how water behaves and interacts is key in many fields of all these three branches of science. Numerical simulation using molecular dynamics can aid in building insight in the behavior and interactions of water. In this thesis molecular dynamics is used to simulate common rigid 3 point water models to see how well they replicate certain physical and chemical properties as functions of temperature. This is done with molecular dynamics program GROMACS which offers a complete set of tools to run simulations and analyze results. Everything has been automated to work with a python script and a file of input parameters. Most of the models follow the same trends and are valid within a limited temperature range.
Vatten är en av de fundamentala byggstenarna för liv, därmed är det även fundamentalt för biologi, kemi och delar av fysiken. Att förstå hur vatten beter sig och interagerar är en stor fråga inom dessa tre grenar av vetenskap. Med molekyldynamik går det att utföra numeriska simuleringar som kan användas som hjälpmedel för att bygga en djupare förståelse för riktigt vatten. I den här uppsatsen så har molekyldynamik använts till att simulera vanliga rigida 3 punkts parametiseringar av vatten för att se hur bra de kan replikera vissa egenskaper som funktioner av temperatur. Simuleringen är gjord med hjälp av molekyldynamik programet GROMACS som ger en fullständig uppsättning verktyg för att simulera och analysera molekylsystem. Alla simuleringar och analys är automatiserat med ett pythonprogram och en fil för parametrar. De allra flesta modeller följer liknande trender och är giltiga inom små temperaturintervall.

Abstract:

The capability and mobility of exploration robots is increasing rapidly, yet missions will always be constrained by one main resource: time. Time limits the number of samples a robot can collect, sites it can analyze, and the availability of human oversight, so it is imperative the robot is able to make intelligent actions when it comes to choosing when, where, and what to sample, a process known as adaptive sampling. Current Mars rover operations give an example of the need for adaptive sampling techniques. Daily plans budget specific operations down to the minute, and each operation is given a maximum of a few hours to complete. However, the capabilities of the rover far exceed the limited plans. For example, the Mars 2020 mission is testing the Planetary Instrument for X-Ray Lithochemistry (PIXL), a spectrometer used to analyze rocks on a microscopic scale. A quick scan of a postage stamp-sized surface can take an hour but is very noisy, yet reducing this noise with a full scan of the surface takes multiple days. Scheduling constraints and communication delay prohibits scientists from reviewing data in real-time and they are thus unable to follow up at any promising sample locations. However, adaptive sampling techniques enable the rover to quickly and autonomously choose a subset of interesting points for detailed follow-up scans. This work advances the state of the art in adaptive sampling for exploration robotics. We take advantage of the fact that rover operations are typically not performed in a vacuum; extensive contextual data is often present, most often in the form of orbital imagery, rover camera images, and quick microscopic scans like those described above. Using this context, we apply advanced Bayesian and nonparametric models to decide where best to sample under a limited budget. Unlike previous works, our approaches reduce the impact of noise on sample site selection, a common problem when using contextual data. The thesis evaluates our methods in three main scenarios. We begin with the general case, in which noisy contextual information of an entire scene is available to the rover. The rover must choose sampling locations that are expected to create a maximally diverse sample set or a sample set that best represents the entire scene. Sampling a point reveals the true underlying data, altering the reward of future points. Next, we demonstrate improvements to adaptive sampling techniques performed at the microscopic scale, as if the rover stopped for a detailed inspection. Mimicking PIXL operations, the rover no longer has full contextual information, but instead collects a quick scan of each point, one at a time, and decides whether or not to perform a full scan at that point before moving on. We demonstrate a Dirichlet-based technique for building a classification of samples, and show improved performance over existing sampling methods. Finally, we consider rover operations the orbital level, demonstrating improvements to rover path selection using satellite maps as contextual data. Here we apply our Bayesian models to maximize the expected yield of samples collected across a number of prospective sampling paths, ultimately choosing the path most likely to maximize our understanding of the terrain.

Abstract:

According to literature, particularly from data obtained from the World Health Organisation, physical inactivity or sedentarism is one of the leading causes of the major non-communicable diseases, which contributes substantially to the global burden of diseases, death and disability. The burden of mortality, morbidity and disability attributable to non-communicable diseases is currently greatest and is continuing to grow in the developing countries. Most declines in physical activity are during the transition from high school to college or university. The aim of the study was to ascertain perceptions of physical activity, specifically
perceived benefits of, perceived barriers and perceived helpful motivational factors to physical activity among tertiary institution students in Rwanda, and to find out whether demographic and background characteristics have an influence on these perceptions.

Abstract:

Health-related quality of life (HRQOL) is a comprehensive construct including physical and psychosocial health functioning. Despite significant health benefits of regular physical activity (PA), over 40% of female college students do not meet recommended PA guidelines to improve their health. This study investigated the influences of individual, social, and physical environmental factors on students’ PA and HRQOL. Participants were 235 female university students who completed validated surveys assessing their perceptions of PA, HRQOL, and social ecological factors. Three hierarchical regressions revealed individual and physical environmental factors as predictors of PA and HRQOL. These findings indicated health professionals need to consider students’ individual factors and physical environmental factors to promote female students’ PA and HRQOL.

Abstract:

The purpose of this research is to investigate undergraduate students&rsquo
mental models about the quantization of physical observables. The research was guided by ethnography, case study, and content analysis integrated to each other. It focused on second-year physics and physics education students, who were taking the Modern Physics course at the Department of Physics, at Middle East Technical University. Wide range of data was collected by interview, observation, test, diary, and other documents during 2008-2 academic semester. The findings obtained from the qualitative analysis of the data indicated the following conclusions: (1) Students displayed six different mental models, defined as Scientific Model, Primitive Scientific Model, Shredding Model, Alternating Model, Integrative Model, and Evolution Model, about the quantization of physical observables. (2) Students&rsquo
models were influenced by the external sources such as textbooks (explanations in textbooks, bringing textbook into the classes, and the use of one or both textbooks), instructional elements (explanations in instruction, taking notes in classes, and studying before and after the classes+taking notes in classes+attending classes regularly), topic order, and classmate
they were influenced by the internal sources such as meta-cognitive elements, motivation, belief (the nature of science and the nature of quantum physics concepts), and familiarity and background about the concepts. (3) The models displayed by students developed with the contribution of these sources in different proportions. Furthermore, although upgrading in models was observed within the cases of quantization, students&rsquo
mental models about the quantization of physical observables are context dependent, and stable during the semester.

Abstract:

The purpose of this study was to assess and enhance the attitudes and knowledge of physical therapy students toward telecommunication technology. A questionnaire was given to appraise the attitudes and knowledge of 156 physical therapy students toward telecommunication technology. The intervention was a one hour presentation on applications relevant to physical therapy practice. The majority of students expressed interest in telecommunication before the presentation, and felt that expanded use of telecommunication was important to the profession. However, only a minority of students demonstrated knowledge about specific medical telecommunication applications. The post-intervention questionnaire showed the presentation to be effective in changing students' attitudes toward telecommunication, and increasing their knowledge relevant to the practice of physical therapy. If physical therapy curricula were to include exposure to telecommunication, perhaps physical therapists will be more inclined to use the technology in the future.

Full text

Abstract:

Physical activity is important to maintain a healthy lifestyle. Levels of physical activity decrease across the lifespan, and findings suggest only between 13-32% of University students are physically active at the recommended level. Research has found that ca. 50% of motivated individuals fail to enact on their intentions to be physically active. The theory of planned behaviour (TPB) was described, limitations and additions identified and its use outlined in three areas of investigation predicting physical activity: motivation, volition and intervention. Method: Student Activity and Lifestyle Study at Aberdeen (SALSA), a web-based survey, invited all students at the University of Aberdeen to respond to three questionnaires across the 2005/06 and 2006/07 academic years. SALSA received responses from 1418 and 1273 participants at the start of each academic year, respectively. Social cognitions (e.g. intention, perceived control), self-reported physical activity levels and attendance to the University’s sport facilities were measured. A double-blind randomised controlled trial investigated the efficacy two planning interventions, delivered via the internet, aiming to increase PA. Results and Summary: Findings suggest that students who are motivated benefit from making plans when, where and how to take part in physical activity, and plan how to cope with potential barriers and obstacles. Participants who are more certain of their intentions, aware of effort, the standards required and monitor themselves are more likely to be physically active, even though they are equally motivated and perceive themselves to be in control. Participant who were active in the past were more likely to attend the University’s sport facilities. However, the planning interventions did not increase students’ activity levels or attendance to the University’s sport facilities. Adherence to intervention protocol was low (between 58.8% to 76.7%) and participants dropping out of SALSA were large across both academic years.

Englezou, Yiolanda. "Bayesian design for calibration of physical models." Thesis, University of Southampton, 2018. https://eprints.soton.ac.uk/427145/.

Full text

Abstract:

We often want to learn about physical processes that are described by complex nonlinear mathematical models implemented as computer simulators. To use a simulator to make predictions about the real physical process, it is necessary to rst perform calibration; that is, to use data obtained from a physical experiment to make inference about unknown parameters whilst acknowledging discrepancies between the simulator and reality. The computational expense of many simulators makes calibration challenging. Thus, usually in calibration, we use a computationally cheaper approximation to the simulator, often referred to as an emulator, constructed by tting a statistical model to the results of a relatively small computer experiment. Although there is a substantial literature on the choice of the design of the computer experiment, the problem of designing the physical experiment in calibration is much less well-studied. This thesis is concerned with methodology for Bayesian optimal designs for the physical experiment when the aim is estimation of the unknown parameters in the simulator. Optimal Bayesian design for most realistic statistical models, including those incorporating expensive computer simulators, is complicated by the need to numerically approximate an analytically intractable expected utility; for example, the expected gain in Shannon information from the prior to posterior distribution. The standard approximation method is "double-loop" Monte Carlo integration using nested sampling from the prior distribution. Although this method is easy to implement, it produces biased approximations and is computationally expensive. For the Shannon information gain utility, we propose new approximation methods which combine features of importance sampling and Laplace approximations. These approximations are then used within an optimisation algorithm to nd optimal designs for three problems: (i) estimation of the parameters in a nonlinear regression model; (ii) parameter estimation for a misspecied regression model subject to discrepancy; and (iii) estimation of the calibration parameters for a computational expensive simulator. Through examples, we demonstrate the advantages of this combination of methodology over existing methods.

In this dissertation, we propose a cyber-physical system model, and based on this model, present algorithms for a set of distributed computing problems. Our model specifies a cyber-physical system as a combination of cyber-infrastructure, physical-infrastructure, and user behavior specification. The cyber-infrastructure is superimposed on the physical-infrastructure and continuously monitors its (physical-infrastructure's) changing state. Users operate in the physical-infrastructure and interact with the cyber-infrastructure using hand-held devices and sensors; and their behavior is specified in terms of actions they can perform (e.g., move, observe). While in traditional distributed systems, users interact solely via the underlying cyber-infrastructure, users in a cyber-physical system may interact directly with one another, access sensor data directly, and perform actions asynchronously with respect to the underlying cyber-infrastructure. These additional types of interactions have an impact on how distributed algorithms for cyber-physical systems are designed. We augment distributed mutual exclusion and predicate detection algorithms so that they can accommodate user behavior, interactions among them and the physical-infrastructure. The new algorithms have two components - one describing the behavior of the users in the physical-infrastructure and the other describing the algorithms in the cyber-infrastructure. Each combination of users' behavior and an algorithm in the cyber-infrastructure yields a different cyber-physical system algorithm. We have performed extensive simulation study of our algorithms using OMNeT++ simulation engine and Uppaal model checker. We also propose Cyber-Physical System Modeling Language (CPSML) to specify cyber-physical systems, and a centralized global state recording algorithm.

Abstract:

Studies have highlighted the prevalence of sedentary behaviours in the university student population and have noted the significant potential for the promotion of physical activity in educational settings for young adults. Following the epidemiological procedure and ecological approach, the main purpose of this thesis focused on the university student population to review the previous research results by a systematic review method (first study), to compare the differences between UK and Taiwanese participants' and relevant effective variables by using a quantitative study method (second study), to have a deeper understanding of the Taiwanese university students' physical activity behaviours by using a qualitative study method (third study), then to evaluate the efficiency of designed interventions in university settings (fourth study). The whole thesis applied the ecological approach to classify the survey variables' effect to university students' physical activity behaviours. A total of 55 published papers were reviewed and majority of studies were conducted in the US using a cross-sectional design. Finding variables consistently related to university students physical activity level were female gender(-), attitude self-efficacy perceived barrier (-), family support (+), physical activity and sport history (+). These survey variables were more consistent in the literature and corresponded to previous adults' study. Some survey variables linked to university student were also found in the literature but still need more studies for this target population to come to a robust conclusion. Seven days recall design measurement and stage of changes survey for physical activity levels were more identified and have been more frequent using in the reviewed papers. Also, more studies on different ethnicity, environmental variables and intervention with different methodology such as qualitative study method are needed to enrich the knowledge of university's students' physical activity behaviours.

Cataloged from PDF version of thesis.
Includes bibliographical references (p. 143-154).
The physical environment in the oceans dictates not only how phytoplankton cells are dispersed and their populations intermingled, but also mediates the supply of nutrients to the surface mixed layer. In this thesis I explore both of these aspects of the interaction between phytoplankton ecology and ocean physics, and have approached this topic in two distinct but complementary ways, working with a global ocean ecosystem model, and collecting data at sea. In the first half of the thesis, I examine the role of mesoscale physical features in shaping phytoplankton community structure and influencing rates of primary production. I compare the output of a complex marine ecosystem model coupled to coarse resolution and eddy-permitting physical models. Explicitly resolving eddies resulted in marked regional variations in primary production, zooplankton and phytoplankton biomass. The same phytoplankton phenotypes persisted in both cases, and were dominant in the same regions. Global phytoplankton diversity was unchanged. However, levels of local phytoplankton diversity were markedly different, with a large increase in local diversity in the higher resolution model. Increased diversity could be attributed to a combination of enhanced dispersal, environmental variability and nutrient supply in the higher resolution model. Diversity "hotspots" associated with western boundary currents and coastal upwelling zones are sustained through a combination of all of these factors. In the second half of the thesis I describe the results of a fine scale ecological and biogeochemical survey of the Kuroshio Extension Front. I found fine scale patterns in physical, chemical and biological properties that can be linked back to both the large scale horizontal and smaller scale vertical physical dynamics of the study region. A targeted genomic analysis of samples focused on the ecology of the picoeukaryote Ostreococcus clade distributions strongly supports the model derived hypotheses about the mechanisms supporting diversity hotspots. Strikingly, two distinct clades of Ostreococcus co-occur in more than half of the samples. A "hotspot" of Ostreococcus diversity appears to be supported by a confluence of water masses containing either clade, as well as a local nutrient supply at the front and the mesoscale variability of the region.

Abstract:

Solving physics problem in university physics education with a computational approach requires knowledge and skills in several domains, for example, physics, mathematics, programming, and modelling. These competences are in turn related to students' beliefs about these domains as well as about learning, and their motivation to learn. The purpose of this thesis was to investigate the role of university physics students' knowledge, beliefs and motivation when solving and visualizing a physics problem using a computational approach. The results showed that expert-like beliefs about physics and learning physics together with prior knowledge were important predictors of the quality of performance. Feelings corresponding to control and concentration, i.e., emotions that are expected to be good indicators of students' motivation were also good predictors of performance. However, intrinsic motivation, as indicated by enjoyment and interest, together with beliefs expressing students' personal interest and utility value, did not predict performance to any higher extent. Instead, my results indicate that integration and identification of expert-like beliefs about learning and concentration and control emotions during learning are more influential on the quality of performance. Thus, the results suggest that the development of students' epistemological beliefs is important for students' ability to learn from realistic problem-solving situations with many degrees of freedom in physics education. In order to investigate knowledge and beliefs structures network modeling has been applied as a novel tool for analysis. Students' epistemic frames are analyzed before and after the task in computational physics using a network analysis approach on interview transcripts, producing visual representations of mental models. The results show that students change their epistemic framing from a modelling task, with expectancies about learning programming, to a physics task, in which they are challenged to use physics principles and conservation laws in order to troubleshoot and understand their simulations. This implies that the task, even though it is not introducing any new physics, helped the students to develop a more consistent view of the importance of using physics principles in problem solving. When comparing students' framing with teachers,' it is shown that although teachers and students agree on the main features of simulation competence in physics, differences in their epistemic networks can be distinguished. For example, while teachers believe that numerical problem solving facilitates fundamental understanding of physics and mathematics, this is not obvious to students. This implies that university teachers need to be aware of these differences as well as students' beliefs in order to challenge students' expectations and to give support concerning the learning objectives of the assignment.

Full text

Abstract:

Cells use lipid membranes to organize and define their chemical environments. All cell membranes are based on a common structure: bilayers composed of phospholipids with two hydrocarbon chains. How did biology converge on this particular solution for cellular encapsulation? The first cell membranes are proposed to have assembled from simple, single-chain lipids, such as fatty acids and their derivatives, which would have been available in the prebiotic environment. Here we argue that the physical properties of fatty acid membranes would have made them well suited for a role as primitive cell membranes and predisposed their evolution to modern, phospholipid-based membranes. We first considered models for primitive membrane self-assembly, which faces significant concentration barriers due to the entropic cost of aggregation and the solubility of single-chain lipids. We therefore identified two physical mechanisms by which fatty acid membrane assembly can proceed from dilute solutions. Thermal diffusion columns, a proposed prebiotic concentration method, drive the formation of fatty acid vesicles by concentrating an initially isotropic solution past the critical concentration necessary for aggregation. Alternatively, mixtures of fatty acids with varying chain lengths, the expected products of abiotic lipid synthesis, intrinsically reduce the concentration barrier to aggregation through their polydispersity. These results motivated us to better understand the phase behavior of fatty acids in solutions. We found that the composition of fatty acid aggregates, whether vesicles or micelles, is also determined by concentration. Fatty acid vesicles feature significant amounts of coexisting micelles, whose abundance is enriched in low concentration solutions. We utilized this micelle-vesicle equilibrium to drive the growth of pre-existing fatty acid vesicles by changing amphiphile concentration. We next considered the evolution of phospholipid membranes, which was a critical and necessary step for the early evolution of cells. We found that the incorporation of even small amounts of phospholipids drives the growth of fatty acid vesicles by competition for monomers with neighboring vesicles lacking phospholipids. This competitive growth would have provided a strong selective advantage for primitive cells to evolve the catalytic machinery needed to synthesize phospholipids from their single-chain precursors. Growth is caused by any relative difference in phospholipid content, suggesting an evolutionary arms race among primitive cells for increasingly phospholipid membranes. What would have been the consequences for early cells of such a transition in membrane composition? We found that increasing phospholipid content inhibits the permeability of fatty acid membranes through changes in bilayer fluidity. For early heterotrophic cells, the emergence of increasingly phospholipid membranes would have therefore imposed new selective pressures for the evolution of membrane transport machinery and metabolism. Our model for early membrane evolution led us to develop prebiotic models for phospholipid chemistry. The assembly of phospholipids from single-chain substrates requires a single reaction: the acyltransfer of an activated fatty acid onto a glycerol monoester or lysophospholipid. We developed a synthetic model for this reaction that incorporates a copper-catalyzed azide-alkyne cycloaddition and showed that it drives de novo vesicle assembly.

Abstract:

Local thermodynamic models are practical alternatives to computationally expensive rigorous models that involve implicit computational procedures and often complement them to accelerate computation for real-time optimization and control. Human-centered strategies for development of these models are based on approximation of theoretical models. Genetic Programming (GP) system can extract knowledge from the given data in the form of symbolic expressions. This research describes a fully data driven automatic self-evolving algorithm that builds appropriate approximating formulae for local models using genetic programming. No a-priori information on the type of mixture (ideal/non ideal etc.) or assumptions are necessary. The approach involves synthesis of models for a given set of variables and mathematical operators that may relate them. The selection of variables is automated through principal component analysis and heuristics. For each candidate model, the model parameters are optimized in the inner integrated nested loop. The trade-off between accuracy and model complexity is addressed through incorporation of the Minimum Description Length (MDL) into the fitness (objective) function. Statistical tools including residual analysis are used to evaluate performance of models. Adjusted R-square is used to test model's accuracy, and F-test is used to test if the terms in the model are necessary. The analysis of the performance of the models generated with the data driven approach depicts theoretically expected range of compositional dependence of partition coefficients and limits of ideal gas as well as ideal solution behavior. Finally, the model built by GP integrated into a steady state and dynamic flow sheet simulator to show the benefits of using such models in simulation. The test systems were propane-propylene for ideal solutions and acetone-water for non-ideal. The result shows that, the generated models are accurate for the whole range of data and the performance is tunable. The generated local models can indeed be used as empirical models go beyond elimination of the local model updating procedures to further enhance the utility of the approach for deployment of real-time applications.

Abstract:

Standardized information and mathematicalmodels, which model the characteristics of the power generationand power transmission systems, are requirements for futuredevelopment and maintenance of different applications tooperate the electrical grid. Available databases such as Nordpoolprovides large amounts of data for power supply and demand [1].The typical misconception with open availability of data is thatexisting power system software tools can interact and process thisdata. Difficulties occur mainly because of two reasons. The firston is the amount of data produced. When the topology of theelectrical grid changes e.g. when a switch opens or closes, the flowof electrical power changes. This event produce changes ingeneration, transmission and distribution of the energy anddifferent data sets are produced. The second problem is therepresentation of information [2]. There are a limited number ofsoftware tools that can analyze this data, but each software toolrequires a specific data format structure to run. Dealing withthese difficulties requires an effective way to transform theprovided data representation into new data structures that canbe used in different execution platforms. This project aims tocreate a generic Model-to-Text (M2T) transformation capable oftransforming standardized power system information modelsinto input files executable by the Power System Analysis Tool(PSAT). During this project, a working M2T transformation wasnever achieved. However, missing functionality in someprograms connected to sub processes resulted in unexpectedproblems. This led to a new task of updating the informationmodel interpreter PyCIM. This task is partially completed andcan load basic power system information models.

Abstract:

There is a need to look at the determinants of exercise behavior in adolescents, as there is a large deficit of research concerning this population. The purpose of this study was to examine Social Physique Anxiety (SPA) and the body shape of adolescents participating in a semester of physical education class. A secondary purpose was to create general profiles by combining the SPA information and the Transtheoretical Model (TM) of behavior change. Middle school students (N= 374) participated by completing a regularly scheduled physical education class and completing the Exercise Behavior Change Survey (which assessed Body Shape, SPA and TM) pre and post semester. The study revealed participation in class had no effect on SPA levels or Body Shape scores, nor did the study reveal any gender differences with these two concepts. Concerning the TM, SPA may not be a factor for progressing through the stages of change, although it may effect which processes were utilized and how one identifies the pros and cons of exercising. The Social Physique Anxiety Scale only reached an alpha of .50, possibly contributing to the lack of relationship between SPA and TM.

Abstract:

Ocean general circulation models of the IPCC class have biases even when simulating present-day conditions, which may bring into question their predictions of future conditions. This dissertation is about tools for, and results from assessing biases in the Community Earth System Model (CESM) ocean component, by itself and when combined with the Biological Ecosystem Cycling (BEC) model. Newly developed tools and their applications are listed. 1. An offline matrix tracer transport model for the ocean component of CESM. 2. A fast Newton-Krylov implicit tracer equilibrium solver for both the annually-averaged and the seasonally-varying circulation. 3. An effective preconditioner for the solver simulating radiocarbon. Application results: For a natural radiocarbon simulation, an equilibrium solution was obtained in 23 model-years, a dramatic decrease from the 4000 model-years reported for time-stepping. The modeled circulation in the deep Pacific Ocean produced radiocarbon ages twice those of observations. 4. A capability for computing the surface origin of water mass fractions as well as the age of the various water masses.

Application results: The North Atlantic was the major supplier of ventilated water to not only the Atlantic, but also the Pacific and Indian Oceans. A lack of formation of bottom water in the Southern Ocean was discovered. 5. A capability for restricting the tracer simulation domain to a limited region of the ocean while retaining the effectiveness of advection and diffusion fields on the boundary. This reduces computational costs and allows separating local versus remote impacts of tracer sources on the biogeochemical tracer concentrations. This capability has the potential to provide a platform for further biogeochemical studies.

Application results: The Indian Ocean region was isolated. Global versus regional circulation effects were determined using radiocarbon. Most of the bias within the region was eliminated by using observational, rather than globally calculated values, on the boundaries. Oxygen production and consumption from a CMIP5 BEC simulation were used to drive a regional oxygen model. Boundary values of oxygen from the CMIP5 BEC simulation were replaced with observations, resulting in less bias within the region. However, significant bias in the location of the Arabian Sea oxygen minimum zone remained.

Public Health
Ph.D.
Contemporary American youth fail to meet national recommendations for physical activity at alarmingly high rates despite well-established protective effects of physical activity on multiple domains of health. There is an established pattern of disparity in physical activity participation whereby girls, those of lower socioeconomic status and those of African American and Hispanic backgrounds are less apt to report regular physical activity in keeping with national recommendations. Large scale investigations to increase the proportion of highly active youth have yet to realize widespread success. In light of emerging evidence suggesting physical activity levels may begin to decline earlier than previously thought, there is a possibility that research and intervention efforts to date may have approached the problem of declining activity after the risk behavior of inactivity had already been established. Despite numerous investigations into factors associated with physical activity in youth, many questions remain unanswered. Among the considerations that are not well understood is when physical activity levels begin to decline for at-risk subgroups of youth and what modifiable individual, interpersonal and/or environmental-level factors are associated with remaining highly active in these populations. This ecologically-based cross-sectional study represents an initial step toward addressing these considerations among elementary and middle school students. Self-reported primary data were collected from a convenience sample of 321 public school students from the 4th, 6th and 8th grade. Students represent the racial/ethnic and socio-economic groups at greatest risk of not meeting national recommendations for physical activity. Study questionnaires queried a range of factors believed to be associated with physical activity, such as availability of social support, self-efficacy for activity, and perceptions of environmental attributes. In addition, two separate physical activity outcome measures were assessed. Factors associated with physical activity at the univariate level (p>0.2) were included in forward stepwise binary regression models to predict reporting of high physical activity. A significant decrease in the proportion of highly active girls was noted between the 4th and 6th grade groups while the proportion of highly active boys did not differ significantly between grade levels. Among 6th and 8th grade students, the difference in physical activity between genders was significant with males reporting more physical activity than females in each grade level. Distinct variables were associated with highly active students in each grade- and gender-specific regression model. After controlling for all other included variables, high social support was most strongly associated with reporting of high activity among girls while for boys in this sample, perceived normal weight status was the strongest predictor of high activity. Among all students, use of daily active transport to school was also strongly associated with reporting of high physical activity. Future investigations involving younger students and utilizing enhanced, longitudinal designs may provide greater insight into the preliminary findings reported in this study.

Syftet med studien har varit att undersöka vad eleverna har lärt sig om kost och hälsa på högstadiet inom ämnena idrott och hälsa samt hem och konsumentkunskap. Undersökningen gjordes med hjälp av enkäter som omfattade totalt 55 elever. Under min utbildning till lärare inom idrott och hälsa samt hem och konsumentkunskap har jag sett att övervikt och ohälsa blir ett allt större problem bland våra ungdomar. Som i sin tur kan leda till dålig självkänsla, utanförskap och en dålig hälsa hos eleverna. Resultatet visade att uppfattningen om den egna kunskapen och den verkliga kunskapen om kost och hälsa var bra hos majoriteten av eleverna. Många elever uppgav att det som påverkat dem mest till deras kostvanor var föräldrarna. Undersökningen visade även att majoriteten av eleverna är medvetna om hur de ska leva ett hälsosamt liv, tyvärr så är det bara drygt hälften som gör det. Mina förhoppningar är att den här undersökningen kommer att vara till hjälp för mig i mitt kommande yrkesliv som lärare.

Abstract

The purpose of this study has been to find out the learning grade of healthy living and diet among young people. Whit this study i tried to get as much information as possible about how much students in upper secondary school has learnt from physical education and home economics. The study was made as a questionnaire where 55 students answered the questions that i had made with the background of my knowledge. During my education to become a teacher I’ve understood that overweight and an interest for a good way of living has gone all worse among youth. This problem could result in bad confidence and psychical problems for the person it involves. The results proved nothing less than that the majority of the students had good knowledge about a healthy way of living. The examination proved that parents are most responsible for what the kids choose to eat. It also proved that almost all students knows the way of a good healthy lifestyle, but only half of the majority goes for the good lifestyle, the other half unfortunately goes for the unhealthy lifestyle. My expectations of this examination are; that it will help me in my future roll as a becoming teacher.
