Full textAbstract:
BACKGROUND: Sleep problems affect people of all ages, race, gender, and socioeconomic classifications. Undiagnosed sleep disorders significantly and adversely impact a person’s level of academic achievement, job performance, and subsequently, socioeconomic status. Undiagnosed sleep disorders also negatively impact both direct and indirect costs for employers, the national government, and the general public. Sleepiness has significant implications on quality of life by impacting occupational performance, driving ability, cognition, memory, and overall health. The purpose of this study is to describe the prevalence of daytime sleepiness, as well as other quantitative predictors of sleep continuity and quality.
METHODS: Population data from the CDC program in fatigue surveillance were used for this secondary analysis seeking to characterize sleep quality and continuity variables. Each participant underwent a standard nocturnal polysomnography and a standard multiple sleep latency test (MSLT) on the subsequent day. Frequency and chi-square tests were used to describe the sample. One-Way Analysis of Variance (ANOVA) was used to compare sleep related variables of groups with sleep latencies of <5 >minutes, 5-10 minutes, and >10 minutes. Bivariate and multivariate logistic regression was used to examine the association of the sleep variables with sleep latency time.
RESULTS: The mean (SD) sleep latency of the sample was 8.8 (4.9) minutes. Twenty-four individuals had ≥1 SOREM, and approximately 50% of participants (n = 100) met clinical criteria for a sleep disorder. Individuals with shorter sleep latencies, compared to those with longer latencies reported higher levels of subjective sleepiness, had higher sleep efficiency percentages, and longer sleep times. The Epworth Sleepiness Scale, sleep efficiency percentage, total sleep time, the presence of a sleep disorder, and limb movement index were positively associated with a mean sleep latency of <5 >minutes.
CONCLUSIONS: The presence of a significant percentage of sleep disorders within our study sample validate prior suggestions that such disorders remain unrecognized, undiagnosed, and untreated. In addition, our findings confirm questionnaire-based surveys that suggest a significant number of the population is excessively sleepy, or hypersomnolent. Therefore, the high prevalence of sleep disorders and the negative public health effects of daytime sleepiness demand attention. Further studies are now required to better quantify levels daytime sleepiness, within a population based sample, to better understand their impact upon morbidity and mortality. This will not only expand on our current understanding of daytime sleepiness, but it will also raise awareness surrounding its significance and relation to public health.

Full textAbstract:
The present study assessed the differential effects of three manipulations of the sleep-wake schedules of college students on their levels of daytime sleepiness as measured by daily subjective ratings. The study was longitudinal and prospective. Following a baseline period (12 days), three experimental conditions were introduced. In the first group students were asked to sleep at least 7.5 hours at night and to avoid taking naps. In the second group, students were asked in addition to follow a regular sleep wake schedule. In the third group students were asked to sleep at least 7 hours at night and to take daily naps. The experimental phase lasted four weeks and overall, compliance was good. A follow up phase (one week) began five weeks past the termination of the experimental phase. The findings indicate that when nocturnal sleep is not deprived, regularization of the sleep-wake schedules lead to reduced sleepiness and improved psychological and cognitive functioning. Subjects in the regular schedule condition experienced greater and longer lasting improvements in their alertness compared with subjects in the other two groups combined. Napping was not found to produce any change in daytime sleepiness, but subjects who had greater increases in the regularity of nap frequency experienced greater decrease in daytime sleepiness. Subjects with evening tendencies benefited most from regularizing their sleep schedules whereas subjects with morning tendencies benefited most from taking naps.

Full textAbstract:
This thesis presents a study of the ionospheric response to dayside magnetopause reconnection. The principal data set employed is the ionospheric convection velocities from the CUTLASS HF radars. In addition to this, images of the ultraviolet aurora from the VIS Earth Camera and the Far Ultraviolet Imager aboard the Polar spacecraft were examined. In situ measurements have shown that there is a time-dependent, periodic nature to magnetic reconnection, with time scales of the order of minutes; the transient nature of magnetopause reconnection is reflected in the ionospheres. In this thesis the plasma velocity fluctuations in the dayside ionosphere were found to be in full agreement with the repetition rates of bursts of reconnection at the magnetopause, as well as with the repetition rates of polarised moving visible auroral forms seen from Earth. The first-ever full vector measurements of ionospheric convection velocity within the footprint of the reconnecting flux tubes revealed that, despite being transient, magnetic reconnection was a large scale process during which layers of magnetic flux were successively peeled from the magnetopause. Directly measured particle precipitation revealed that particles originating the reconnection region was found to be present on the same magnetic field lines as the HF radar signature of the reconnected field lines. The multi-instrument study of the ionospheric responses to reconnection demonstrated that the measured ionospheric convection velocities are inextricably linked to measured ultraviolet aurora. Energetic particle precipitation from the magnetosphere into the atmosphere via field-aligned currents excites auroral emissions, and field-aligned current estimates from measured ionospheric convection velocities were found to be in excellent agreement with the aurora.

Filtness, Ashleigh J. "Obstructive sleep apnoea and daytime driver sleepiness." Thesis, Loughborough University, 2011. https://dspace.lboro.ac.uk/2134/8338.
Full textAbstract:
Driver sleepiness is known to be a major contributor to road traffic incidents (RTIs). An initial literature review identified many studies reporting untreated obstructive sleep apnoea (OSA) sufferers as having impaired driving performance and increased RTI risk. It is consistently reported that treatment with continuous positive air pressure (CPAP) improves driving performance and decreases RTI risk, although most of these studies are conducted less than one year after starting treatment. UK law allows treated OSA patients to continue driving if their doctor states that treatment has been successful. Despite the wealth of publications surrounding OSA and driving, 6 key areas were identified from the literature review as not fully investigated, the: (i) prevalence of undiagnosed OSA in heavy goods vehicle (HGV) drivers in the UK; (ii) impact of sleep restriction on long term CPAP treated OSA compared with healthy controls; (iii) ability of treated OSA participants to identify sleepiness when driving; (iv) impact of one night CPAP withdrawal on driving performance; (v) individual difference in driving performance of long term CPAP treated OSA participants; (vi) choice of countermeasures to driver sleepiness by two groups susceptible to driver sleepiness, OSA and HGV drivers. Key areas (i) and (vi) were assessed using questionnaires. 148 HGV drivers were surveyed to assess OSA symptoms and preference of countermeasures to driver sleepiness. All participants completing the driving simulator study were also surveyed. 9.5% of HGV drivers were found to have symptoms of suspected undiagnosed OSA. Additionally the OSA risk factors were more prevalent for HGV drivers than reported in national statistics reports for the general population. The most effective countermeasures to driver sleepiness (caffeine and a nap) were not the most popular. Being part of a susceptible group (OSA or HGV driver) and prior experience of driver sleepiness did not promote effective choice of countermeasure. Key areas (ii) to (v) were assessed using a driving simulator. Driving simulators present a safe environment to test participants in a scenario where they may experience sleepiness without endangering other road users.

Full textAbstract:
Solar wind mass, energy and momentum can be transferred to Earth's magnetosphere at the magnetopause with the shocked magnetosheath acting as an interface between the two regions. In particular the magnetosheath pressure is important in terms of the position and motion of the magnetopause, which in turn can have effects throughout the dayside magnetosphere. A variety of transient phenomena often occur in the magnetosheath and in this thesis one example is studied, namely pulses in the magnetosheath dynamic pressure, using multipoint spacecraft observations to investigate their origins and magnetospheric impacts and illuminate dayside magnetospheric dynamics. Simultaneous observations in the solar wind, foreshock and magnetosheath reveal an interval of dynamic pressure pulses that did not exist upstream of the bow shock in the pristine solar wind or foreshock and appear consistent with previous simulations of solar wind discontinuities interacting with the bow shock, which predict large amplitude pulses when the local geometry of the shock changes. A statistical study of these structures, however, reveals their predominant origin near the quasi-parallel shock, typically under steady interplanetary magnetic fields, suggestive that the foreshock is important in their generation. The enhanced pressure on the magnetopause due to these pulses can perturb the boundary, exciting ultra-low frequency waves in the magnetosphere and travelling convection vortices in the ionosphere, similar to the response to pressure variations of solar wind origin. However, in this case the response is smoother and on longer timescales than the sharp, impulsive pressure variations and often a collective effect of numerous pulses. Conditions at the magnetopause are often inferred from suitably time lagged measurements of the pristine solar wind taken far upstream of Earth at the L1 Lagrangian point. However, such methods cannot predict the precise locations and times of dynamic pressure pulses in the magnetosheath, which directly drive magnetospheric dynamics.

Martin, Sascha E. "The effect of sleep fragmentation on daytime function." Thesis, University of Edinburgh, 1997. http://hdl.handle.net/1842/28545.
Full textAbstract:
Sleep fragmentation is the term used to describe brief awakenings or microarousals from sleep which are less than 15 seconds long and often occur without the awareness of the sleeping subject. Arousals is the collective term for awakenings >15 seconds and microarousals < 15 seconds. Patients with sleep apnoea/ hypopnoea syndrome (SAHS) have recurrent upper airway obstructions during sleep usually terminated by arousals and decreases in oxygen saturation. They suffer from impaired daytime function which correlates weakly with their nocturnal hypoxemia and sleep fragmentation. These are interrelated making it difficult to distinguish which is the cause of daytime dysfunction in SAHS patients. This thesis examines the impact of sleep fragmentation alone on daytime function by inducing sleep fragmentation in normal subjects and studying their subsequent daytime function. A problem associated with studying sleep fragmentation is its poor definition. Current arousal definitions use a combination of a greater than 1 second increase in EEG frequency with or without increased EMG activity depending on sleep stage. This can lead to difficulties in comparing results between studies. Although the American Sleep Disorders Association (ASDA) has published guidelines on visual scoring of arousals they have not been validated or compared with other arousal definitions currently in use. Therefore 3 different arousal definitions and 1 definition of awakening were compared in SAHS patients. The definitions were (1) ASDA (3 seconds), (2) ASDA modified to 1.5 seconds, (3) Cheshire 1.5 second. The awakening was defined as a Rechtschaffen and Kales' stage shift to wakefulness. There were significantly more arousals of any kind than awakenings, and significantly more 1.5 second arousals by either definition than ASDA arousals. However not all apnoeas and hypopnoeas were terminated by visible EEG arousals with at best, 83% of respiratory events being terminated by 1.5 second ASDA arousals. There were weak but significantrelationships between microarousals scored by any definition and daytime sleepiness on the multiple sleep latency test (MSLT). The first sleep fragmentation protocol examined the effects of one night of induced visible EEG arousals on the daytime function of normal subjects. The subjects were objectively sleepier during the day after fragmentation as measured by both the MSLT and the maintenance of wakefulness test (MWT). Subjects had altered mood on the UWIST mood adjective checklist following sleep fragmentation; energetic arousal was diminished all day except at 12.00, hedonic tone was decreased at 10.00, and tense arousal was increased at 08.00 and 10.00. Subjects had impaired performance on 2 tests of cognitive function; Trailmaking B, a test of mental flexibility, and on PASAT 4 seconds, a test of sustained attention. These deficits were similar to those seen in SAHS patients prior to CPAP therapy. There are subgroups of patients with sleep apnoea whose apnoeas and hypopnoeas occur when they are lying supine or when they are in REM sleep. This allows them to obtain periods of uninterrupted sleep which may be sufficient to overcome any daytime dysfunction that may have occurred due to their REM or posture related sleep apnoea. Therefore 2 fragmentation paradigms were compared; regular fragmentation every 90 seconds of sleep, and clustered fragmentation every 30 seconds for 30 minutes every 90 minutes. There was no difference in arousal frequencies between study nights. There were no differences in daytime function despite significantly less stage 2 and more slow wave sleep on the clustered fragmentation night. This suggests that deficits in daytime function are dependent on sleep fragmentation and not stage 2 or slow wave sleep. Not all apnoeas and hypopnoeas are terminated by visible EEG arousals but are terminated by transient increases in blood pressure. The impact of these transient increases in blood pressure on daytime function are unknown. Therefore daytime function was compared after an undisturbed night's sleep and one night of sleep fragmentation to cause blood pressure elevations alone without coincident visible EEG arousals. There wassignificantly less slow wave sleep on the fragmented study night but there was no difference in visible EEG arousals between study nights. Non-visible sleep fragmentation made subjects sleepier during the day on the MSLT and MWT, and decreased hedonic tone upon awakening. There was no effect on cognitive function. Finally changes in EEG frequencies during visible EEG arousals were examined using Fast Fourier Transformation (FFT). There were significant increases in all physiological frequencies of human sleep within 5 seconds of the start of an arousal. During the non-visible fragmentation night alpha EEG power was determined with FFT. There was a significant increase in peak alpha power within 5 seconds of a tone whether that tone produced a visible EEG arousal or not. This suggests that computerised analysis of the EEG may be useful in measuring sleep fragmentation

Full textAbstract:
Veiling glare has always existed in cars, but during the last years it has been brought up as a big problem. One reason is that glossier materials are being used in car interior design. Another reason is that the customers who buy the cars are getting more quality conscious. They demand to get top quality for the high price that they pay for a car, and veiling glare problems could be regarded as “low quality”.
Veiling glare is when light hits the car interior and reflects into the windshield, causing mirror-like images in the windshield (ghost images). This can impair the driving experience in two ways. It can lower the contrast of the road scene and it may be a cluttering for the driver.
This work handles daytime veiling glare from dashboard reflectance. The purpose was to investigate the area and to see if Saab can avoid the problem with veiling glare by using virtual prototyping (see chapter 3.3.1). This has been done by examining if the light
simulation software Speos can be used to simulate and predict veiling glare, and thereby be used as a tool for better design.
Key words: Veiling glare, dashboard, windshield, Speos, virtual prototyping.

The concept of sleep disturbance is rather vague. Many people claim to suffer from sleep disturbance, but yet find it hard to describe exactly what they mean by the label in subjective terms. Sleep researchers have a similar problem, it is difficult to describe what is meant by sleep disturbance either in an objective or a subjective way, and harder still to relate sleep disturbance to sleepiness shown the following day.

Full textAbstract:
Ten untreated patients with narcolepsy-cataplexy and ten age and sex matched normals between the ages of 20 and 71 underwent pupillometric analyses immediately prior to each of five Multiple Sleep Latency Test (MSLT) sessions. Although narcoleptics were sleepier in terms of both their Stanford Sleepiness Scale (SSS) ratings and their latencies to sleep onset, the baseline pupil diameter, pupillary light reflex and pupillary orienting response did not differentiate between groups. Narcoleptics did, however, exhibit a significantly greater frequency of spontaneous oscillations in the dark-adapted state than did controls. These findings indicate that pupillary stability may serve as a supplementary diagnostic tool for narcolepsy-cataplexy. The results are discussed with the view that psychosensory restoration of alertness, among other extraneous variables, must be controlled for when utilizing pupillometric techniques. A review of the literature indicates a variety of methodological and statistical shortcomings that must be amended. Suggestions are made for improving the reliability and validity of the pupillometric approach.

The characters of Forlorn Days have been beaten down, be it personally or professionally. These stories are meant to present these characters as they struggle in their own indecisions and adversities. Some are more successful than others, while some come to the realization that it is nearly impossible to escape their flaws. The worlds they occupy are filled with a sense of disillusionment, whether it be soul crushing jobs, fractured relationships, or a lack of communicating with those around them. The characters that populate these stories are looking for a connection of any kind to break out of the fates that await them. In this yearning to break out of their disillusionment, they find that it’s more difficult than they thought. Life continues to go around regardless of the decisions they have made.

Full textAbstract:
Luminous Days is a representation of my artistic vision, literary goals, and social influences. Artistically, I intend to create fiction that is aesthetically appealing. This aesthetic appeal includes the presence of a distinct narrative voice, realistically rendered settings, multidimensional characters, meticulous attention to diction, and sentence construction. The literary goal I hold in the highest regard is the creation of a body of work that demonstrates continued growth in my craft.
What I intend to render in my thesis is an accurate portrayal of the effects that drugs on the lives of my characters, and more specifically the relational strains of this disease on my characters. Luminous Days was not intended to be a mere exploration of drug addiction through the eyes of an addict, but an examination also, of the effects of people addicted to drug profits. Throughout this thesis I hope readers will glean insights into a culture this is at once marginalized, exploited, glorified, and criticized.
Artistically I hoped to create a story that is universally appealing by ascribing my characters problems and issues that are common to the human experience. I feel specificity in character depiction was a major component of that goal. I hoped to humanize my characters by ascribing them distinct desires, hopes, fears, and triumphs. In reading this thesis I want writers to realize one important thing: My work on this story is far from complete. This is a first draft of an almost completed manuscript. Read this work knowing that there are many drafts to come in terms of the evolution of my story.

Full textAbstract:
Sleep is a critical modulator for daytime functioning, health and wellbeing and has a pivotal role in motor memory consolidation. It is for these reasons that sleep is a potentially important part of stroke care. However, this idea is severely under researched. It is necessary to explore sleep behaviour in stroke patients and the importance of healthy sleep for recovery and neurorehabilitation. More specifically, investigate the extent to which sleep may be a key modulator for motor neurorehabilitation success. It is the central aim of this thesis to contribute to the understanding of the sleep behaviour and daytime functioning in patients with chronic physical deficits after stroke and to explore the potential role of sleep for neurorehabilitation. Furthermore, this is the first known study to monitor sleep behaviour during a motor neurorehabilitation trial and assess outcome within this context. The research aimed to: 1) make a substantial contribution to the under researched field of post stroke sleep, 2) address some of the limitations imposed on previous studies, 3) focus on a specific cohort, 4) examine sleep in the context of a neurorehabilitation programme. The patient cohort employed in this research comprised chronic stroke patients (>'12 months) with upper limb hemiparesis. It was found that sleep and daytime functioning disturbances were prevalent in approximately one third of patients. Interestingly, patients were not generally aware of the severity of their daytime functioning deficits. Sleep and daytime functioning were mildly related to motor recovery and neurorehabilitation. In conclusion, sleep clearly has a role in stroke patient quality of life, recovery and neurorehabilitation outcome, however further research using alternative assessments of sleep are necessary. The findings of this thesis have implications for post stroke management including increasing medical knowledge and adjustments in rehabilitation protocols that favour sleep.

Includes bibliographical references (p. 129-132).
This thesis is basically concerned with improving the environment in which office workers go about their business. In the first chapter - The office environment - the extent of the problem and the necessity for improving the environment is discussed. Deep-plan buildings and associated interior layouts like the "bull-pen" and open planning are defined. Chapter 2- Daylighting - deals with issues relating to the incorporation of daylighting into buildings. Here, the advantages of daylighting- both in quantitative measurements as well as qualitative aspects - are put forward; and the implications on interior planning discussed. . Chapter 3 - The courtyard array - brings together the ideas of the preceding chapters and proposes a broad, low building with multiple atria as a solution to the problem of daylighting the deep-plan office. Earlier studies dealing with illumination, thermal comfort, view content, acoustics and economic evaluation are discussed in relation to the proposed array. A discussion on the importance of physical scale models in the evaluation of a building's lighting performance is at the beginning of Chapter 4: Daylighting models. This chapter continues with a description of the models made; and ends with tables of illumination measurements and daylight factor calculations from the physical models. These measurements show the validity of the day lit array concept for day lighting a deep-plan building. In Chapter 5 - Economic evaluation - the thermal performances of a non-daylit and a daylit building are compared, using the computer program Solar 5. The operating costs of the two alternatives show the extent of potential savings from the use of day lighting. The concluding chapter of this thesis puts in perspective issues relating to the day lighting of deep-plan offices. It discusses the economic trade-offs inherent in the design of a different type of building form. The final question - whether the non-daylit module or the day lit module will be built - can only be decided by the management of the office. The purpose of my thesis is to give them an idea of what daylighting can mean to their company: in creating a better work environment and lowering operating costs.

Full textAbstract:
We studied the global climatology of mid- and low-latitude F region daytime neutral winds using extensive measurements by the Wind Imaging Interferometer (WINDII) instrument on board the Upper Atmosphere Research Satellite (UARS). Quiet-time winds are mostly poleward and westward during the day, and are generally 5-20 m/s smaller in the longitudinal sector closest to the magnetic pole, compared to longitudinally averaged winds. The pre-noon zonal winds are less westward with increasing solar flux, while the post-noon meridional winds are less poleward . Our quiet-time results are in good agreement with the NCAR ThermosphereIonosphere- Electrodynamics General Circulation Model (TIEGCM).
We computed residual winds by subtracting quiet-time values calculated along the satellite orbit, which effectively removes average measurement bias. Using these residuals, we studied the average change in the winds under disturbed conditions. The zonal disturbance winds are mostly westward, increase with latitude, and have largest values in the late afternoon sector. In general, the meridional perturbation winds are equatorward, increase linearly with latitude, and decrease from morning to afternoon hours. The zonal and meridional perturbations increase roughly linearly with Kp. We developed empirical analytical models for the disturbance winds from 60° to the equator; these model winds are in poor agreement with results from the empirical Horizontal Wind Model. There are also important discrepancies between the average perturbations winds from WINDII and TIEGCM.
We studied the average time-dependent development of disturbance winds during geomagnetic storms. The onset of a storm is characterized by equatorward surges, mostly in the morning sector, that reach the equator in about 2 h. These surges lessen 5-6 h after the onset of a storm, but subsequently increase, reaching their largest values about 15 h after the start of the storm before leveling off or diminishing. Following the end of typical storms, the disturbance winds decrease quickly but oscillate for at least one 8-9 h cycle. We developed time-dependent analytical models of the disturbance winds as a function of the polar cap index at key storm time lags. Our results are consistent with predictions from theoretical models. (146 pages)

This thesis examines the relationships between a wide range of nocturnal sleep and breathing variables and daytime function. Additionally this thesis examines the use of subjective and objective measures of daytime sleepiness, to determine which tests provide the most useful information for SAHS patients. A pilot study found that neither the 103 patients' nor their partners' Epworth rating of sleepiness were strong predictors of SAHS severity. In 150 patients with a wide range of SAHS severity, relationships between nocturnal events and daytime function were examined using newer definitions of arousal and measures of sleep continuity. A broad battery of daytime tests were used including the Maintenance of Wakefulness Test (MWT) and the Short Form (SF)-36. Unlike previous studies, all correlations were controlled for age and awake oxygen saturation, known to influence the variables measured. The current study also examined these correlations in an unselected patient sample with a range of disease severity. The study showed a lack of strong relationships between conventional nocturnal sleep and breathing variables and daytime function. Few baseline variables significantly predicted CPAP use. Daytime function measures were compared within the 150 patients. The Multiple Sleep Latency Test (MSLT) and the MWT displayed a weak, discordant relationship. Measures of cognitive function, psychological well-being and subjective sleepiness better related to the MWT than MSLT, suggesting that the MWT may be a more useful tool in assessing functional impairment in sleep apnoea. The studies presented in this thesis demonstrate a lack of identified factors affecting daytime function in a group of unselected SAHS patients. This may be due to inter-individual patient variability. Also, more sophisticated nocturnal SAHS measures should be examined, as should more 'real-life' daytime assessments, such as ambulatory EEG recorded during a patient's normal daily routine.

Find full textAbstract:
The "University" is under pressure to address both local and general requirements from society towards a phenomenon called globalisation. In Brazil, the Ministry of Education has tried, without success, to promete institutional change. Confronted by this situation a process initiated by an internai change agent and based upon the introduetion of Action Research was itself the subject of this AR Study by the change agent. This thesis draws upon the findings of that AR and uses it to critically examine the potential to foster change within the higher education context In Brazil using AR. The research was designed in two synchronous processes taking place at two different leveis. The first is the facilitation of the uptake of Action Research by a group of academic staff, and the second is the research into that process as a piece of Action Research in its own right by the change agent/facilitator. Facilitation of change has been described as taking place in three phases: a) Mobilization; b) Implementation; and c) Continuation. Throughout such phases in this case data were systematically gathered by the use of five instruments of data collection: 1) Observation; 2) Diary; 3) Questionnaires; 4) Interviews; and 5) Sociogram. Results show my personal learning in facilitating this process of change and two main contributions to knowledge. The first is ene which, though local and specific, may nevertheless speak to the challenges faced by other practitioners. Exemplified in this study by the criticai exploration of the 'Daisy Model' of introducing AR that led to it modification into the 'Flower Model'. The second is that new knowledge which appears to be more generalisable and for which a case can be made for its wider applicability. Again exemplified in the continuous and disruptive process of change that unfolded to reveal a suitable framework for the use of Action Research as a vehicle of change in a rural university in Brazil where ali actions were based on four central principies that emerged from the research: neutrality, voluntary participation, time and motivation. The future success and sustainability of the change processes begun are contingent upon the reaction of the current management of the institution. Five scenarios are examined and a second phase for this AR project is suggested that attempts to address the issues raised..A "Universidade" está sob pressão para atender às exigências locais e gerais da sociedade em relação a um fenômeno chamado globalização. No Brasil, o Ministério da Educação tentou, sem sucesso, promover mudanças institucionais. Confrontado com esta situação, um processo iniciado por um agente de mudança interna e baseado na introdução da Action Research foi ele próprio o objeto deste Estudo AR pelo agente de mudança. Esta tese baseia-se nas descobertas dessa AR e usa-a para examinar criticamente o potencial de promover mudanças dentro do contexto da educação superior no Brasil usando AR. A pesquisa foi projetada em dois processos síncronos que ocorrem em dois níveis diferentes. A primeira é a facilitação da adoção da Pesquisa-Ação por um grupo de funcionários acadêmicos, e a segunda é a pesquisa sobre esse processo como uma peça de Pesquisa-Ação em seu próprio direito pelo agente / facilitador da mudança. A facilitação da mudança foi descrita como ocorrendo em três fases: a) Mobilização; b) Implementação; e c) Continuação. Ao longo de tais fases, neste caso, os dados foram sistematicamente coletados pelo uso de cinco instrumentos de coleta de dados: 1) Observação; 2) Diário; 3) questionários; 4) Entrevistas; e 5) Sociograma. Os resultados mostram minha aprendizagem pessoal ao facilitar esse processo de mudança e duas contribuições principais para o conhecimento. O primeiro é aquele que, embora local e específico, pode, no entanto, falar dos desafios enfrentados por outros praticantes. Exemplificado neste estudo pela exploração critica do 'Modelo Daisy' de introdução de AR que levou a modificação no 'Modelo de Flor'. O segundo é aquele novo conhecimento que parece ser mais generalizável e para o qual um caso pode ser feito para sua aplicabilidade mais ampla. Novamente exemplificado no processo contínuo e disruptivo de mudança que se desdobrou para revelar um quadro adequado para o uso da Pesquisa-Ação como veículo de mudança em uma universidade rural no Brasil onde todas as ações foram baseadas em quatro princípios centrais que emergiram da pesquisa: neutralidade , participação voluntária, tempo e motivação. O sucesso futuro e a sustentabilidade dos processos de mudança iniciados dependem da reação da atual administração da instituição. Cinco cenários são examinados e uma segunda fase para este projeto de RA é sugerida para tentar abordar as questões levantadas.

Full textAbstract:
Obstructive sleep apnea (OSA) is a disease characterized by nighttime airflow limitation, hypoxemia, arousal from sleep, and elevated sympathetic activity and blood pressure. With time, this nighttime dysfunction gives rise to daytime hypertension and a heightened risk for cardiovascular disease. Current treatment options for OSA are not always effective for all patients and the gold-standard intervention, continuous positive airway pressure, has discouraging compliance rates. The work set forth in this dissertation has as its focus a novel intervention for sleep apnea known as inspiratory muscle training (IMT). IMT improves respiratory function and cardiovascular health but has not been implemented previously as a treatment for OSA. As such, Study 1 implements IMT in individuals with mild and moderate OSA, with the objective of assessing the effects of training on the cardio- respiratory parameters of this disease. We randomly assigned 24 individuals with mild- moderate OSA into one of two groups: training vs. placebo, to assess the effects of 6 weeks of training on overnight polysomnography, subjective sleep quality, blood pressure, circulating inflammatory T cells, and plasma catecholamine content. Our results show IMT- related improvements in sleep quality, reduction in the number of arousals from sleep and in periodic limb movements following 6 weeks of training. Most important, IMT was associated with a significant reduction in systolic (~12 mmHg) and diastolic (~5 mmHg) blood pressure, relative to sleep apneics who undertook 6 weeks of placebo training. Additionally, individuals in the training group exhibited ~30% lower levels of sympathetic activity, as measured by plasma catecholamines, relative to placebo trained peers. The mechanism(s) that underlie the IMT-related reductions in blood pressure and sympathetic activity remain to be determined. However, in an effort to determine the precise respiratory stimulus that contributes to the results obtained in Study 1, we subsequently assessed the specific respiratory components of IMT to determine which component (large intrathoracic pressures and/or large lung volumes) likely contributes to the reduction in blood pressure in Study 1. The results of this study conducted in normotensive adults show that respiratory training that entails either large negative or positive intrathoracic pressures reduces systolic and diastolic blood pressure in healthy young adults. Importantly, neither the generation of large lung volumes alone nor performance of daily paced breathing is sufficient to lower blood pressure. Study 3 is a methodologic study that has as its focus upper airway electromyography (EMG) and the utility of assessing EMG activity across a range of conditions and breathing tasks in wakefulness. Because OSA traditionally has been viewed as the result of neuromuscular dysfunction of the upper airway that occurs during sleep, the aim of this work was to develop a "fingerprint" of healthy electromyographic activities during the day in healthy adults across a range of breathing tasks, body positions, and from two different muscle compartments of the upper airway. The findings from this study demonstrate regional differences in muscle activity that vary as a function of body position and task. These data from healthy subjects provide the basis of comparison for subsequent studies in individuals with obstructive sleep apnea.

Full textAbstract:
In a 9-month prospective study, sleep and daytime functioning were compared in a community sample of 86 participants aged 25-50 years: 43 meeting DSM IV criteria for primary insomnia (26 women & 17 men); and 43 controls (32 women & 11 men). Assessments were conducted at baseline, 4 and 8 months, and included: the Pittsburgh Sleep Quality Index; Spielberger StatefTrait Anxiety Inventory; Eysenck Personality Questionnaire, Beck Depression Inventory; Fatigue Severity Scale; SF-36; Epworth Sleepiness Scale; Dysfunctional Beliefs About Sleep Scale; Sleep Hygiene and Practices Scale, Sleep Disturbance Questionnaire and the Psychomotor Vigilance Task PVT. An instrument to assess the occupational consequences of insomnia (the Occupational Impact of Sleep Questionnaire; OISQ) was also developed in the course of the study. PWI versus control group comparisons were made with repeated measures multivariate ANOVAs. Differences were consistently and significantly maintained on measures of state (F = 15.85 P <0.001) and trait anxiety (F = 23.46; P < 0.001), depression (F = 18.37; P < 0.001), fatigue (F = 22.20; P < 0.001), and neuroticism (F = 11.09; P < 0.001). Among PWI, mental health (F = 14.04; P < 0.001), pain (F = 6.92; P < 0.001), role-emotion (F = 10.94; p < 0.001), general health perceptions (F = 4.77; P < 0.05), social functioning (F = 6.58; P < 0.01) and energy and vitality (F = 32.08; P < 0.001), on the SF-36, were consistent with inferior health related QoL. In addition, pre-sleep arousal (F = 14.76; P < 0.001), sleep hygiene (F = 35.26; P < 0.001) and sleep disturbance (F = 72.32; P < 0.001) were significantly worse within PWI. Subjectively reported TIB (F = 9.38; P < 0.01), SOL (F = 11.17; P < 0.01) and WASO (F = 21.10; P < 0.001), remained greater within PWI, with SE (F = 15.29; P < 0.001), TST (F = 9.38; P < 0.01) and subjective sleep quality (F = 29.57; P < 0.001) greater within controls. Data averaged over the duration of data collection (252 days) found PWI reported an average SOL >30 minutes, an average WASO of> 30 minutes, SE < 80%. Analysed in terms of night to night sleep quality, both PWI and controls showed a pattern of 'good' (sleep efficiency >80%) and 'poor' (sleep efficiency <80%) nights. However, the probability of individual poor nights remained consistently and significantly higher for PWI across the 9 months of the study. Actigraphy data failed to confirm between group differences in sleep, and correlation with diary measures was low in both groups. PVf performance showed instability. Significant group differences found at baseline, were no longer present at subsequent data collection points. Data support the inconsistency surrounding objective performance among PWI within the literature. However, the inconsistency can be attributed to greater change within control participant's performance, rather than within PWI. Data identified the existence of a stable subgroup of PWI reporting symptoms of daytime sleepiness. Daytime sleepiness was found to be a temporally stable feature for this sub-group of PWI, who also Showed a distinctive psychological profile compared to PWI who did not report daytime sleepiness. No difference, however, was observed in subjectively reported sleep structure, quality or daytime performance between these subgroups of PWI. Insomnia subgroup analyses suggest a trait-like difference between sleepy and non sleepy PWI.The OISO showed an acceptable level of internal consistency reliability (alpha 0.93); and successfully discriminated between PWI and controls. The OISO also showed consistent correlations with measures of global sleep quality and subjective sleep parameters. Expressed in terms of comparative percentage decrement, PWI showed a consistent 10% decrement in subjective occupational performance when compared with controls. The OISO shows that absenteeism and punctuality may not capture the full impact of insomnia on workplace performance.

Full textAbstract:
Research has shown that riding a motorcycle can potentially be much more dangerous than operating a conventional vehicle. There are factors inherent in driving or riding a small two wheeled vehicle, such as a motorcycle, moped or even bicycle that can potentially decrease their ability to be seen or noticed by other drivers. This disadvantage is reflected in the disproportionate over-representation of injuries and/or fatalities incurred by this particular driving group. This creates a significant problem which deserves dedicated evaluation as to causative factors and/or influential variables. The following research was conducted with intentions to investigate the topic of motorcycle conspicuity so as to further explain the variables which positively contribute to a motorcycle being seen and to supplement the body of knowledge that currently exists on this topic. This study specifically evaluated the influence of sex, age, motorcycle lighting conditions, and vehicular daytime running lights upon one's ability to effectively detect a motorcycle within a "high fidelity" simulated environment. This research additionally sought to examine the feasibility and validity of using a novel fixed base "high fidelity" simulator for the evaluation of motorcycle conspicuity. The results from this research clearly indicate a link between vehicular DRLs and the effective detection of motorcycles and also support previous research as to the effectiveness of motorcycle DRLs. Additionally, these results suggest that as one ages, certain degradations in vision, cognition, and physiology occur which decrease one's performance in detecting and responding to a motorcycle. These findings additionally provide support for the use of a "high definition" fixed base simulator as a valid technology for the evaluation of motorcycle conspicuity.Ph.D.

Full textAbstract:
The aim for this bachelor thesis is to determine the altitude of the auroral acceleration region occuring on the dayside. Substantial work has already been done on this topic, but for occurrence at the nightside. In this paper only negative quasi-static potential structures were considered, as they are the main contributor for producing aurora. The data for this study was obtained by the Cluster satellite constellation, and was processed by scripting in MATLAB in order to find the events for this paper. Namely, 17 passages of the auroral oval, especially occurring within two magnetic local time sectors, symmetrically around noon (12 MLT). The results show that the acceleration region occurs from below 2 RE up to an altitude of 4.5 RE with an average of 3.40 ± 0.84 RE, considerably higher than for the nightside. More specifically, fore and afternoon sectors have altitude averages of 2.44 ± 0.49 RE and 4.00 ± 0.26 RE, respectively. A significant difference between the two sectors. By regarding the pseudo altitude and classifying identified events as either -part of a larger scale coherent structure or - a small scaleauroral arc, a general occurrence pattern and height-dependence of the AAR was discovered. The large-scale arcs occur on average at a higher altitude (3.89 ± 0.22 RE) than the small-scale arcs (2.82 ± 0.80 RE).
