A non-dimensional quantity that is used to describe fluid flows is the Knudsen numbers Kn. Kn = l/L where l is the mean free path of the particles and L a typical length scale. For Knudsen number much smaller than 1 the particles can be described as a continuum. For these applications, Navier-Stokes equations are sufficient to describe the flow. For larger Knudsen values the second order Burnett equations can be used. Doing a linear stability analysis on the Burnett equations it can be shown that the equations are not stable for all wave numbers. A method of stabilizing the equations has been suggested by Lars Söderholm, see (Söderholm, 2006). This results in the Hybrid Burnett equations. For the purpose of investigating the ability for the Hybrid Burnett equations to describe physical flows, the phenomenon of shock waves will be numerically treated for different cases.

A high amplitude sinusoidal wave will be integrated forward in time using Runge-Kutta fourth order scheme as it travels along the x-axis. Fourier’s method will be used for spatial discretization. This wave will with time form a shock wave. The high gradient in the wave profile will result in a reflected wave that is traveling in the opposite direction of the original wave. As the amplitude of the original wave and the self reflected wave decay we will have two small amplitude waves where non-linear effects can be neglected. From this old age wave the amplitude will be compared with the analytical solutions of the Burgers’ equation. The dependence of the amplitude of the self reflected wave of parameters such as the Reynolds number and Knudsen numberwill be investigated.

With the success of the O Brother, Where Art Thou? soundtrack, T Bone Burnett spent his cultural capital on repurposing traditional American music in subsequently successful soundtracks and artistic productions, providing a spark for a 21st century cultural movement that moves beyond music. This study aims to position Burnett has a cultural catalyst by grounding his work, and those abiding by a similar ethic, in the American South. In the process, I examine what Burnett’s soundtracks and select artistic productions communicate about contemporary Southern cultures and identities, while negotiating the ever-enigmatic generational issues of identity and authenticity. By extending the analysis to artists, producers, and cultural tastemakers who operate by a similar ethic as Burnett as well, I also address the characteristics of and spark igniting the preservationist, heritage movement in contemporary roots music, and how this music community contributes to ongoing conversations regarding contemporary Southern identity? The purpose of my study is to explore these connections, the culture in which they reside, and most specifically the role T Bone Burnett plays in a contemporary cultural movement which seeks to (re)present a traditional American music ethos in distinctly Southern terms. Furthermore, I will set the movement within the contemporary context in which such sounds, symbols, and narratives reside. Within this study, I read films, songs, soundtracks, albums, fashion, and performances, each loaded with symbols, archetypes, and themes that illuminate intersection past and present issues of identity. By weaving ethnographic interviews (with musicians, producers, and other cultural tastemakers) with cultural analysis, I investigate how relevant cultural issues are being negotiated, how complicated discussions of history, tradition, and heritage feed the ethic, and how the American South as a perceived distinct region factors in to the equation.

Studiens främsta syfte har varit att undersöka två konstaterade fall av burnout bland svenska elittränare. Undersökningsområdet har valts med intentionen att öka omvärldens förståelse och kunskap om, vad det är som gör att en tränare drabbas av burnout. I studien har även förekomsten av burnout inom den svenska elittränarkåren i ishockey undersökts, samt deras reflektioner av sin arbetsplats. Maslach och Jacksons definition av Burnout från 1996, ligger till grund för undersökningen. Den beskriver burnout som ”ett syndrom av känslomässig utmattning, cynism och minskat personligt engagemang, vilket kan förekomma bland individer vars arbete innefattar att arbeta med andra människor”. Definitionen omfattar sedan några år även en persons relation med dennes arbete.

Två utbrända tränare intervjuades efter en framarbetad intervjumall. Frågorna i intervjumallen byggde på innehållet i den enkäten som användes vid insamling av data från elitishockeytränarna i studien. Enkäterna var sammansatta av demografiska frågor, öppna frågor och vetenskapliga mätinstrument. Intervjumallens och enkäternas uppbyggnad gav förutsättningar för jämförelse och analys av den insamlade informationen. Enkätundersökningen genomfördes under OS-uppehållet 2006. Det aktuella urvalet var 25 ishockeytränare, aktiva i Elitserien och Allsvenskan. De flesta av tränarna arbetade på heltid. Alla deltagare i studien var män.

De intervjuade tränarna upplevde det som svårt att begränsa sitt engagemang och ansvarsområde. Det blev lätt ensamt i arbetet och de hade svårt att säga ifrån i rätt tid, vilket skyldes av den skam och känsla av misslyckande som tränarna upplevde. Resultaten från Maslach Burnout Inventory (MBI) i enkäten, visade att tränarna upplevde perioden november-december som tyngre än januari-februari. Jämfört med normvärden för parametern ”Känslomässig Utmattning”, uppvisade tränarna ungefär samma resultat i november-december, men klart lägre resultat än normvärdena i januari-februari. För parametern ”Negativ Attityd” i MBI, var resultaten ungefär lika med normvärdena. Samtidigt var resultaten för parametern ”Personligt Engagemang” mycket högre än normvärdena, både för perioden november-december och januari-februari.

Tränarna som intervjuades uttryckte att, möjlighet till att prata av sig, få stöd, och speciellt att få stöd när det går dåligt, var något som skulle ha hjälpt dem att undvika att drabbas av burnout. Mentorskap föreslås som hjälpinstrument för tränare, med förhoppningen att det kan hjälpa tränare på samma sätt som aktiva idrottare hjälps och stöttas av mental träning. Saker som skulle kunna förbättras i tränarens arbetssituation berör tränarens beteende, arbetsmiljö, och hur personer omkring tränaren agerar. I framtida undersökningar föreslås att det inkluderas studier av reaktioner och reflektioner bland tränarens aktiva, för att öka möjligheten att upptäcka fall av burnout i tid.

The aim of this study was to examine two cases of stated burnout among Swedish elite coaches. The research area was chosen, with the intention to increase the knowledge and understanding about what makes a coach burn out. In the study, there has also been examined, what existing amount of burnout and burnout symptoms there are among Swedish elite ice hockey coaches, and what their reflections are on their workplace and how it can be improved. The base definition of burnout in this study is Maslach and Jacksons from 1996. It describes burnout as “a syndrome of Emotional exhaustion, Cynism and less personal engagement, which can be the case among individuals working with other humans”. The definition also comprises a person’s relation to his or her work, from some years back 

Two burned out coaches were interviewed, with a compounded template of questions. The template was constructed from the survey, which was part of the study of the elite ice hockey coaches. The questions were of demographic, “open answered”, and scientific measurement character. The way the template was established, made it possible to examine and compare the results. The template survey was done during the time of the Olympic break in 2006 and 25 ice hockey coaches in the Swedish Elite League and Second Division participated. Most of the coaches work as full time coaches. All participants in the study were men

The Interviewed coaches revealed having trouble defining their engagement and their area of responsibility. They often felt lonely in their coach occupation, and that it was difficult to say no to things in time, because of feelings of shame and failure. The MBI results showed that coaches experienced November and December as heavier months than January and February. Compared to the MBI’s standard results for the parameter Emotional Exhaustion, the coaches scored about the same results for the November-December period, but lower for the January-February period. For the parameter Cynism, the results were about the same as the standard results, but for the parameter Personal Engagement, the coaches scored much higher than standard. That counted for both the period November-December, as for the period January-February.

To be in a position where you feel you have support and people to talk to when you need it, were things pointed out by the coaches, which they thought could help them work and feel better, and to avoid to be burned out. The contact with a person, like a mentor, is suggested to be a good helping tool for coaches, as it should be compared to the way you support athletes with mental training. Things which could be better in the coaches work situation, concerns the coaches behavior, the work environment, and how people who interact with the coaches act. For future research we suggest focusing on athletes’ reflections and reactions as result of burned out coaches’ behavior, to be able to spot burned out coaches in time.

Many studies highlights the correlation between personality and burnout but a limitation in previous studies is the lack of longitudinell data, wich is preferable to show strong causal relationships. The purpose of this study is to explore if personality-traits can predict changes in levels of burnout across time. Longitudinal data from nurse students in Sweden participating in the LANE study are used. The personality constructs chosen are personality traits from The Five Factor theory, adjusted into traits specifically applicable in personality and health research. Two dimensions of burnout were used to identify levels of burnout, exhaustion and disengagement. The method used to explore changes in burnout levels, and associations to personalitytraits, is multiple regressionanalysis. The results show that the personality traits Impulsivity, Negative affectivity and Antagonism can predict burnout. The longitudinal data allow us to make stronger predictions than earlier studies made.

This study explores the pervasiveness of job fatigue in Emergency Room nurses. It identifies factors that contribute to nurse burnout, including job dissatisfaction and workplace bullying, and explores strategies for assessing and reducing fatigue syndrome. As the literature suggests, there is a link between nurse burnout and patient safety. These findings are expected to help organizations develop strategies to reduce stress in the workplace and develop wellness programs. Upon using an interviewing process, the study found several themes that pointed to the key factors of increased ER nurse burnout, and provided several implications as to the changes that need to be made to improve the ER department environment. Some of the key findings included the need to hire more staff, make supervisors and management more approachable and available, and increasing support to ER nurses. Doing so will clearly help mitigate the problem of high stress levels among ER nurses and help to prevent the likelihood of burnout.
