Evaluating the Effectiveness of a Wearable Technology for Increasing Physical ActivityNieves, Christopher Michael 31 October 2014 (has links)
Obesity in America has grown widespread over the past decade and is a significant social issue that affects many families. Identifying interventions that are not only effective in the natural environment but are easy to implement are ideal for helping individuals engage in more fitness related activities. The purpose of this study was to evaluate the effectiveness of the NikeTM FuelBand for increasing physical activity in 3 adults. Additionally, a goal setting procedure was used to test if it enhanced the effects of the NikeTM FuelBand. Three measures were collected as part of the study, NikeTM Fuel, daily steps, and caloric expenditure. The NikeTM FuelBand was found to be effective at increasing all participants NikeTM Fuel score, daily steps, and caloric expenditure daily average from baseline to intervention phase. The goal setting procedure was found to be effective at increasing NikeTM Fuel point score, daily steps, and caloric expenditure daily average scores for two of three participants.

La inseguridad, el temor al delito y su relación con la sobrecobertura de los medios de comunicaciónHormazábal Véliz, Tomás Gustavo January 2017 (has links)
Memoria (licenciado en ciencias jurídicas y sociales) / Autor no autoriza el acceso a texto completo de su documento / “La masificación de los medios de comunicación es algo que sin duda alguna ha traído
importantes beneficios para la humanidad. Sin embargo, como todo gran avance, hay
consecuencias negativas. Y una de ellas es la sobrecobertura de las noticias sobre
delitos, que tiene una gran influencia en la sensación de inseguridad que sufre nuestro
país. Después de todo, Chile es uno de los países con menores niveles de criminalidad
en América Latina, pero, por el contrario, tiene uno de los niveles más altos de temor
al delito. En este trabajo, se expondrá el concepto de la sensación de inseguridad, y
de cómo los medios influyen en ella. Además, se tratará este tema de acuerdo a
diversas teorías de la criminología. Luego, para demostrar la existencia de la
sobrecobertura de noticias delictivas, se expondrán los resultados de un levantamiento
de datos, tomados de un noticiero de televisión. Por último, se darán algunas ideas
para combatir este problema y buscar una solución a la sensación de inseguridad
artificial presente en nuestra población.”

Using Self-Monitoring and Goal Setting to Increase Swimming in AdultsAbraham, Sarah Rose 16 September 2015 (has links)
Many people in the United States do not engage in the recommended levels of physical activity. Self-management strategies, including self-monitoring and goal setting, are among the interventions that have been used to increase physical activity in adults. Visual feedback has also been incorporated into interventions to increase physical activity. Minimal research has focused on increasing swimming behavior. The current study investigated the effectiveness of self-management strategies to increase swimming activity in adults. An automated recording device (watch) was used to collect data on participants’ swimming behavior. The effect of self-monitoring in the form of a self-graphing intervention to increase swimming activity was evaluated. If self-graphing alone was not effective, goal setting was added to the intervention. Three participants showed an increase in swimming activity when self-graphing was implemented. Two participants showed little or no change in activity across all phases. This study did not include any reinforcement contingencies for engaging in an increase in swimming activity. Future research directions are discussed.

Improving Consistency of Goal Attainment to Increase Physical ActivitySolley, Elizabeth Anne 14 June 2014 (has links)
Researchers have successfully increased physical activity with self-monitoring, goal setting, and feedback. Goal attainment is a crucial part of what makes goal setting successful; however, it is often unreported in the literature or implied that goals were not reached consistently. A potential way to achieve this consistency is to create an action plan, or a detailed account of exactly how and when the individual will engage in the desired physical activity to reach his or her goal. This study evaluated whether making a detailed action plan would allow individuals to reach their physical activity goals more consistently than when using goal setting and self-monitoring alone. Action planning increased goal attainment for all participants but only resulted in increased physical activity for 2 of 3 participants. Future research should replicate this study to validate these findings and further explore methods for improving the success of goal setting as an intervention.

A Monte Carlo Approach for Exploring the Generalizability of Performance StandardsCoraggio, James Thomas 16 April 2008 (has links)
While each phase of the test development process is crucial to the validity of the examination, one phase tends to stand out among the others: the standard setting process. The standard setting process is a time-consuming and expensive endeavor. While it has received the most attention in the literature among any of the technical issues related to criterion-referenced measurement, little research attention has been given to generalizing the resulting performance standards. This procedure has the potential to improve the standard setting process by limiting the number of items rated and the number of individual rater decisions. The ability to generalize performance standards has profound implications both from a psychometric as well as a practicality standpoint. This study was conducted to evaluate the extent to which minimal competency estimates derived from a subset of multiple choice items using the Angoff standard setting method would generalize to the larger item set. Individual item-level estimates of minimal competency were simulated from existing and simulated item difficulty distributions. The study was designed to examine the characteristics of item sets and the standard setting process that could impact the ability to generalize a single performance standard. The characteristics and the relationship between the two item sets included three factors: (a) the item difficulty distributions, (b) the location of the 'true' performance standard, (c) the number of items randomly drawn in the sample. The characteristics of the standard setting process included four factors: (d) number of raters, (e) percentage of unreliable raters, (f) magnitude of 'unreliability' in unreliable raters, and (g) the directional influence of group dynamics and discussion. The aggregated simulation results were evaluated in terms of the location (bias) and the variability (mean absolute deviation, root mean square error) in the estimates. The simulation results suggest that the model of using partial item sets may have some merit as the resulting performance standard estimates may 'adequately' generalize to those set with larger item sets. The simulation results also suggest that elements such as the distribution of item difficulty parameters and the potential for directional group influence may also impact the ability to generalize performance standards and should be carefully considered.

Places and spaces of the writing lifeFahey, Diane Mary, University of Western Sydney, School of Communication and Media Studies January 1999 (has links)
This study investigates and characterises the ways place and space occur in Eavan Boland's Object Lessons, May Sarton's Journal of a Solitude, Anne Dillard's The Writing Life, and a selection of journal material accompanied by poetry. The author's purpose in doing this is to gain insight into the creative processes of these writers and the nature of their engagement with the ongoing venture that Anne Dillard has termed 'the writing life'. This phrase, while evoking a sense of duration and commitment as regards writing, also invites questions about how such a vocation takes shape within the life of a writer. Both the terms 'place' and 'space' come trailing. Each may describe inner experiences, as well as pertaining to the realm of physical perception. Each is also a current focus of critique and contestation in various disciplines - for example, those of anthropology and geography - and by feminist thinkers.The author's introduction refers to some of these revisionings. Findings are summarised in the conclusion. / Doctor of Philosophy (PhD)

Mean Value Modelling of a Diesel Engine with Turbo Compound / Medelvärdesmodellering av en dieselmotor med kraftturbinFlärdh, Oscar, Gustafson, Manne January 2003 (has links)
<p>Over the last years, the emission and on board diagnostics legislations for heavy duty trucks are getting more and more strict. An accurate engine model that is possible to execute in the engine control system enables both better diagnosis and lowered emissions by better control strategies. </p><p>The objective of this thesis is to extend an existing mean value diesel engine model, to include turbo compound. The model should be physical, accurate, modular and it should be possible to execute in real time. The calibration procedure should be systematic, with some degree of automatization. </p><p>Four different turbo compound models have been evaluated and two models were selected for further evaluation by integration with the existing model. The extended model showed to be quite insensitive to small errors in the compound turbine speed and hence, the small difference in accuracy of the tested models did not affect the other output signals significantly. The extended models had better accuracy and could be executed with longer step length than the existing model, despite that more complexity were added to the model. For example, the mean error of the intake manifold pressure at mixed driving was approximately 3.0%, compared to 5.8% for the existing model. The reasons for the improvements are probably the good performance of the added submodels and the systematic and partly automatized calibration procedure including optimization.</p>

Contemprorary Russian Environmental policy: problems, players and priorities. The case of Pskov Region and environmental agenda-setting process.Lundqvist, Anastasia January 2003 (has links)
<p>From the beginning of nineties, when significant changes took place, Russia began to elaborate new environmental policy and designed new patterns for responding the environmental problems. The paper tried to make a contribution to our understanding of environmental policy and policy processes within the Russia in general terms and to the nature of environmental agenda setting in Pskov region in more specific terms. This thesis is therefore explores environmental agenda setting process in Russia taking into consideration contemporary trends in the analysis of policy- making, such as inclusion of non-state actors as well as role of ideas shaping actors attitudes and behaviour. The purpose of the thesis is to study the relationship between transnational forces and interactions, national policy and local political developments and the role of various agents and institutions in agenda setting of the regional environmental policy-making. The frame of reference is constituted by a theoretical combination of the agenda-setting model with constructivist approach in order to broaden our investigation of the implications of environmental policy-making, impact of political culture upon construction of environmental issues, and transformations in the public policy. By focusing on Pskov region case, the paper identifies and discusses a number of reasons why environmental issues are found on the margins of the political agenda. A central argument is that in the absence of effective governance in the Pskov region, international agents together with regional interest groups formulate environmental agenda. The paper concludes that, even though, the mentality of environmentalism is set through the foreign assistance, the processes of learning from international cooperation may contribute to attainment of regional environmental objectives.</p>

Reward Systems : To set up goals, appraise and reward employees in large companiesHagos, Helen, Sonnert, Helena January 2004 (has links)
<p>Background and purpose: Aspects such as the character of the organization and the composition of the work force have an impact on the company’s choice of how to reward and evaluate the employee. In large companies with employees from different professions and at different levels problems connected with the evaluation and the compensation of the employee may arise. The purpose of this thesis is to examine how this type of companies evaluate and reward the employees. Further we will look into the problems that may arise connected to the evaluation and the compensation of the employee. </p><p>Results: In the process of evaluation the greatest difference between the employees from different professions and operations can be found in the goals that are set and the measures that measure the fulfilment of the goals. In regard to the evaluation of employees at different levels the greatest differencecan be found in the character of the measures. When rewarding employees companies tend to have a homogeneous policy for employees from all operations and professions. The difference is greater between employees at different levels. As the number of operations and levels of the company increases it gets harder to set goals that are relevant to each operation and individual as an increasing number of aspects related to these operations must be considered. In addition it is difficult to design rewards which are cost efficient and valued by all employees. These difficulties arise as individuals’ preferences are affected by their working environment and as different preferences are created in different operations and at different levels.</p>

Automatic Exposure Correction And Local Contrast Setting For Diagnostic Viewing of Medical X-ray ImagesPehrson Skidén, Ottar January 2010 (has links)
<p>To properly display digital X-ray images for visual diagnosis, a proper display range needs to be identified. This can be difficult when the image contains collimators or large background areas which can dominate the histograms. Also, when there are both underexposed and overexposed areas in the image it is difficult to display these properly at the same time. The purpose of this thesis is to find a way to solve these problems. A few different approaches are evaluated to find their strengths and weaknesses. Based on Local Histogram Equalization, a new method is developed to put various constraints on the mapping. These include alternative ways to perform the histogram calculations and how to define the local histograms. The new method also includes collimator detection and background suppression to keep irrelevant parts of the image out of the calculations. Results show that the new method enables proper display of both underexposed and overexposed areas in the image simultaneously while maintaining the natural look of the image. More testing is required to find appropriate parameters for various image types.</p>
