Full textAbstract:
The American College of Sports Medicine (ACSM) recommends older adults (OA)
spend 30min/5d/wk engaging in moderate intensity physical activity (MVPA). PURPOSE: To
determine the efficacy of detailed feedback (FB) to increase OA time spent in MVPA compared
to a verbal recommendation (VREC) and control (CON) group. METHODS: Sixty-eight women
recruited from senior-based programs for an 8-wk, 3-intervention arm trial, were randomly
assigned to 1 of 3 groups: VREC, FB, and CON. Individuals meeting ACSM recommendations
were excluded. All participants wore an accelerometer (ACCEL) to monitor 8 weeks of daily
physical activity. VREC were read/received ACSM recommendations similar to mass media
dialogue promoting MVPA and asked to meet recommendations by the 8-wk point. FB walked 3
d/wk on a monitored indoor walking track, and on their own 2 d/wk. FB received all VREC
procedures, received MVPA walking instruction (HR monitored) and weekly ACCEL feedback
(time spent in MVPA and MVPA goals for the next wk). CON continued their normal activities.
RESULTS: Differences were noted between all 3 groups at Week 4 (p ≤ 0.05) and Week 8 (p ≤ 0.05).
This reflects improvement in both the FB and VREC as well as a greater improvement by the FB
compared to VREC. FB improved 264% over 8 weeks. VREC improved 85% from baseline to Week 8.
There was no change in the CON. Difference between groups with respect to meeting ACSM
recommendations (yes/no) were noted (, p ≤ 0.01). The only group to improve was FB.
CONCLUSIONS: Providing simple feedback significantly improved time spent in moderate intensity
physical activity by the 4th week. Based on the results of this study, which indicate that the detailed
feedback is more effective than recommendation alone, this walking program should be implemented by
healthcare providers as a means to improve the amount of moderate intensity physical activity engaged in
by older adults.Thesis (M.A.)--Wichita State University, College of Health Professions, Dept. of Public Health Sciences

Full textAbstract:
The continual increase in the population of older adults in the next 50 years envisages an increase of dependants on the family and the Government. Assisted Living technologies are information and communication technologies to assist, improve and monitor the daily living of the old and vulnerable population by promoting greater independence and providing a safe and secure environment at a reduced cost. Most of the assisted living technologies are passive sensor-based solutions where a number of embedded or body-worn sensors are employed or connected over a network to recognize activities. Often the sensors are obtrusive and are extremely sensitive to the performance of the sensors. Visual data is contextually richer than sensor triggered firings. Visual data along with being contextual is also extremely sensitive. Since visual data is intrusive, a qualitative study among older adults within the community was carried out to get a context of the privacy concerns of having a camera within an assisted living environment. Building on the outcomes of the focus group discussions, a novel monitoring framework is proposed. Following the framework, Activity Level, as an effective metric to measure the amount of activity undertaken by an individual is proposed. Activity Level is estimated by extracting and classifying pixel-based and phase-based motion features. Experiments reveal that phase-based features perform better than pixel-based features. Experiments are carried out using the novel Sheffield Activities of Daily Living Dataset, which has been developed and made available for further computer vision research for assisted living.

Full textAbstract:
Automatic recognition of events in video is an immensly challenging problem. If solved, the number of potential domains in which such a system could be deployed is vast and growing; including traffic monitoring, surveillance, security, elderly care and semantic video search to name but a few. Much prior research in the area has focused on producing a solution that is tailored towards one of these applications, applying methods which are most appropriate given the constraints of the target domain. For the moment, this remains to some extent the only practical way to approach the problem. The aim in this thesis is to build a high-level framework for event recognition which is in the main generic and widely transferrable, yet allows domain-appropriate elements to be incorporated. A detector is constructed for low-level events which is based on dense extraction of Histograms of Optical Flow. This descriptor has only recently been adopted by the event detection community, and as such there are aspects of the features which have not been optimized. This thesis performs extensive experimentation on normalization scheme and finds that the strategy most widely in use is suboptimal compared to one of the alternatives proposed. The detector is then trained on a challenging real world domain to run in a sliding window fashion on continuous video input. A high level model which exploits temporal relations between different event types is constructed. The model is designed with transferrability and computational tractability in mind. Several methods are benchmarked for learning the distributions over time differences between pairs of events. Three different connection strategies are proposed and evaluated for creating a tree structured prior that permits fast, exact inference. An efficient iterative optimization scheme is presented for handling scenarios which contain unknown numbers of event instances. Finally, the model is extended in a Conditional Random Field framework that allows weights to be learned to balance the response from independent detectors with the pairwise temporal relationships.

Full textAbstract:
In today’s highly competitive trading climate it is getting more important to understand the fundamentals of the orderbook and how it works in practice in order to stand out in the competition. Better knowledge of the orderbook statistics can be applied in areas such as high frequencyand execution trading. Therefore the focus of this study is to determine the probabilities of the settlement prices of financial instruments traded on a public order-driven market exchange i.e to predict the probabilities regarding whether the next executed trade will happen on the bid or on the ask side. The mathematical methods used in this study are logistic regression and Maximum Likelyhood (ML)-estimation for optimization of parameters. First the parameter matrix was optimized using orderbook data on the OMXS30 future and then use the estimated model on an out-ofsample test. Keywords: Logistic Regression, Orderbook, level-2 dataI dagens marknad råder hög konkurens vilket gör det viktigt att förstå fundamentan bakom orderboken och hur handeln med finansiella instrument fungerar i praktiken. Det utvecklas flera nya och förbättrade informationsystem och tradingalgoritmer varje dag och detta skärper konkurensen och försvårar möjligheten att tjäna pengar på tradingverksamhet. Med ökad förståelse för orderboken och dess fundamenta kan utvecklingen inom databaserad handel exempelvis exekverings- och högfrekvenshandel drivas på. Därför fokuserar jag denna studie på orderboken genom att försöka uppskatta sannolikheten för om nästkommande trade kommer att ske på köp- eller säljsidan av orderboken på en orderdriven marknad som Stockholmsbörsen. I undersökningen har logistisk regression och Maximum Likelyhood (ML)-skattning använts för att bestämma koefficienterna i den skattade statistiska modellen. Data är hämtade från OMXS30 terminen där kovariaterna är volymen på varje prisnivå för köp- respektive säljsidan i orderboken. Den skattade modellen testas på andra data än som använts för att skatta modellen. Nyckelord: Orderbok, logistisk regression, Maximum Likelyhood

Cavill, Nick. "National-level approaches to increasing participation in health-enhancing physical activity." Thesis, University of Salford, 2010. http://usir.salford.ac.uk/26610/.
Full textAbstract:
Increasing participation in regular physical activity is a key public health goal in many countries, but there is little consensus among experts on effective, national population level strategies to change physical activity behaviour. This thesis brings together the findings from thirteen published articles, reports and book chapters, from a variety of disciplines and methodologies. It explores how public policy can be modified to support physical activity; the potential role of social marketing; the supportive changes that can be made to the natural and built environment; and interventions focused on increasing rates of walking and cycling. Evidence is presented in the context of the social ecological model, which describes multiple-level influences on health. The thesis shows that there is unlikely to be any single, simple, neat solution to the problem of physical inactivity. Shaping more active societies requires a comprehensive, system-wide, ecological approach, based on the best available evidence. Action should be taken that combines changes to public policy and the environment with social marketing, and a focus on walking and cycling. This needs to be based on a clearer understanding of the importance of physical inactivity, and a clearer and stronger commitment to tackle the problem at a societal level.

Full textAbstract:
Syfte: Studiens syfte var att undersöka samband mellan hur universitetsstudenter skattar sin fysiska aktivitetsnivå och hur de registrerar aktivitetsnivå med hjälp av dagbok samt att se om de kom upp i ACSM (American College of Sport Medicine) och WHO´s (World Health Organisation) rekommendationer. Metod: Studien hade en icke experimentell, deskriptiv och korrelerande design där 26 försökspersoner, två män och 24 kvinnor, rekryterades via anslag. De fick först svara på en enkät och därefter registrera sin aktivitet via en 7-dagars aktivitetsdagbok. Resultat: Studenterna ansåg inte att de hade en stillasittande livsstil och alla deltagare utom en ansåg sig komma upp till ACSM´s rekommendationer av fysisk aktivitet 30 minuter per dag av måttlig intensitet alla dagar i veckan. Trettiofem procent kom inte upp i WHO´s rekommendationer och av dessa överskattade 67% sin fysiska aktivitetsnivå. Sextiofem procent kom inte upp i ACSM´s rekommendationer och av dessa överskattade 94% sin aktivitetsnivå. Konklusion: Studenterna hade en låg fysisk aktivitetsnivå utifrån ACSM´s rekommendationer och majoriteten av de som inte levde upp till WHO och ACSM rekommendationer överskattade sin fysiska aktivitetsnivå. Det krävs dock mer omfattande studier för att dra några generella slutsatser då denna studie hade en skev könsfördelning och ett lågt antal deltagare. Keywords: Self-estimation, Perception, Activity diary, Physical Activity level, Overestimation.Objectives: The main objective was to compare self-estimated physical activity level with the registration of physical activity level among college students. A secondary objective was to investigate if the subjects reached the level of physical activity recommended by American College of Sport Medicine (ACSM) and World Health Organisation (WHO). Method: A non-experimental, descriptive and correlated design. 26 subjects, 2 men and 24 women, were included. A questionnaire was used to investigate their perceived level of physical activity and a 7-day activity diary was used for the registration of activity level. Results: The students did not perceive to have a sedentary lifestyle and all subjects except one believed they reached the level recommended by ACSM. Thirty-five percent did not reach the recommendations of WHO and 67% of these overestimated their physical activity level. Sixty-five percent did not reach ACSM´s recommendations and 94% of these overestimated their physical activity level. Conclusion: The students had a low physical activity compared to the recommendations of ACSM and subjects who did not reach WHO and ACSM´s recommendations overestimated their physical activity level. Due to the small number and adverse gender in the subjects, numerous studies need to be done in order to complete any further conclusions.

Full textAbstract:
Objective: Utilizing a conceptual model of the impact of disasters on children╒s functioning, the current study examined unhealthy diet and sedentary activity levels of children exposed to Hurricane Ike. Exposure stressors (perceived and actual life threat) and recovery stressors (hurricane-related stressors and major life events), were hypothesized to be associated with unhealthy diet and sedentary activity. Exposure stressors, recovery stressors, and child demographic characteristics were also expected to be associated with posttraumatic stress (PTS) symptoms. It also was predicted that physical activity would attenuate the relationship between recovery stressors and children╒s PTS symptoms. Finally, the feasibility of collecting health behavior information from children was examined. Method: Utilizing a cross-sectional design, 204 children (51% girls; M age = 9.23, SD = .79; grades 3 and 4) from Galveston, Texas were evaluated 8 months after Hurricane Ike (Time 1). At Time 1, children completed self-report measures of traumatic experiences, major life events, PTS symptoms, height and weight, and health behaviors. 53 children were reevaluated two weeks later (Time 2) to examine the stability and validity of health-related measures. Children completed a second measure of their height, weight, and health behavior measures, and actual measurements of height and weight were also taken. Results: Consistent with expectations, exposure and recovery stressors were associated with sedentary activity and PTS symptoms. Exposure stressors were indirectly related to sedentary activity and PTS symptoms through recovery stressors. However, contrary to expectations, stressors were not associated with unhealthy diet. African American ethnicity, Hispanic ethnicity, and female gender were related to PTS symptoms through recovery stressors. Physical activity did not attenuate the relationship between recovery stressors and children╒s PTS symptoms. In terms of health behaviors, children╒s self-reported weight was both stable and valid from Time 1 to Time 2. Self-reported height was stable but invalid. Measures of children╒s unhealthy diet and sedentary activity showed moderate stability. The measure of physical activity exhibited low stability and low validity. Conclusions: Sedentary activity may be a particularly important health behavior to examine after disasters. Implications for schools, families, and future research are discussed. Alternative measures of physical activity should be considered.

Full textAbstract:
Transcutaneous spinal direct current stimulation (tsDCS) is a non-invasive technique that can be used to modulate spinal function. It consists of applying a low-level direct current (DC) across the skin to modulate spinal excitability using surface electrodes. Recent research indicates that this technique can relieve musculoskeletal pain. In this study, we investigate the effect of a 20-min anodal tsDCS (2.5 mA) protocol applied over the thoracic spine on pressure pain threshold (PPT) measured in the thigh, leg and foot in healthy young adults. One primary focus of this study was to determine whether physical activity level, as a potential modulator of pain perception, could influence individual responses to tsDCS. A secondary aim was to also address the role of sex as another potential modulator of pain response. Thirty-five healthy young adults (age 18-35) were recruited for this study. Participants were assigned to either a moderately active (n=21, 12 females), or highly active group (n=14, 8 females) based on a self-report questionnaire (International Physical Activity Questionnaire). The effects were determined by comparing PPT measures at the three sites (thigh, leg, foot) at three time points with respect to tsDCS application: T0: before, T1: immediately after, and T2: 30 min post-application. Results from a multivariate analysis of variance revealed a large main effect of time (F=5.3, p<0.001) on PPTs. Univariate tests (F>16.2, p<0.001) confirmed that PPTs were significantly elevated post-application. In addition, the analysis revealed a significant “Group X Time” interaction (F=2.8, p=0.03), which was explained by a larger elevation in PPTs (thigh site) in the highly active group when compared to the moderately active group. No main effect or interaction was found for sex. Altogether, these results confirmed the anti-nociceptive effects of tsDCS application on mechanical pain threshold and further point to the importance of physical activity as a personal factor susceptible to modulate response to tsDCS.

Full textAbstract:
Overweight and obese children have increased risks for multiple preventable diseases and conditions which can impair their physiological health and significantly increases the overall cost of their healthcare. Free mobile applications and technology for weight loss, dietary tracking, and physical activity may be quite useful for monitoring nutritional intake and exercise to facilitate weight loss. If so, nurses are well positioned to recommend such tools as part of their efforts to prevent childhood obesity and help children and parents better manage childhood obesity when it is present. However, there are no guidelines that nurses can use to determine what applications or technologies are most beneficial to children and their parents. The purpose of this project is to develop such guidelines based on a review of the scientific literature published in the last 5 years. Articles regarding healthy-lifestyle promoting mobile applications and technological approaches to health and fitness interventions were identified by searching articles indexed by CINAHL, Psychinfo, Medline, ERIC, IEEE Xplore, and
Academic Search Premier. Identified articles were assessed using Melnyk’s hierarchy of evidence and organized into tables so that implications for research and suggestions for practice could be made.B.S.N.

Kim, Se In. "The association between the supraglottic activity and glottal stops at the sentence level." Thesis, University of Iowa, 2015. https://ir.uiowa.edu/etd/1660.
Full textAbstract:
Contrary to the previous belief that any presence of supraglottic activity indicates presence of hyperfunctional vocal pathology, Stager et al. (2000, 2002) found out that supraglottic compressions do occur in normal subjects. In fact, dynamic false vocal fold compressions during production of phrases with a great number of glottal stops were noted. The present study hypothesized that a similar pattern s would be observed at sentence level, where at least 50% or higher incidence of dynamic FVF compressions would be observed at aurally perceived glottal stops and other linguistic markers, such as vowel-initial words, /t/ final words, punctuations and phrase boundaries, where glottal stops were likely to occur.
Nasendoscopic recordings were obtained from 8 healthy subjects (2M; 6F) during production of selected sentence stimuli.. Their audio recordings were rated by two judges to detect the location of glottal stops. Then, the video images were analyzed to categorize the presence and absence of dynamic and static false vocal folds (FVF) or anterior posterior (AP) compressions. Results indicated that the incidence of dynamic FVF compressions was 30%. Nevertheless, the average incidence was elevated at aurally perceived glottal stops and at the linguistic contexts that are known to be associated with glottal stops compared to other contexts.

According to motivational theory physical self-perceptions are crucial to the intrinsic desire to engage in physical activity through play, games, and sport. While there has been prolific research with middle primary and older children little is known of the importance of young children's physical self-concept and their motivation to engage in physical activity. This study had three major purposes. Firstly it aimed to examine the relationship between children's self-concept, their attraction to physical activity, and level of physical activity. The second purpose of the study was to examine differences between boys' and girls' self-concept, attraction to physical activity and level of physical activity. The third purpose was to examine the effectiveness of an intervention programme designed to enhance children's level of physical activity.

Full textAbstract:
Objective: To explore the relationship between individual factors (i.e. affect, self-efficacy, and self-regulation), social and environmental factors, and their effects on the level of participation in physical activity (PA). Design: Undergraduate and graduate students (N = 386) completed 11 online measures assessing physical activity level and reactions to physical activity participation at Time 1, 9 online measures at Time 2, and a measure of physical activity participation at Time 3. Measures included those assessing affective reactions to PA, outcome expectancy, self-efficacy, self-regulation, social support, and perceptions of the environment. Results: Affect had a small total effect on METs (Ã =.13, p=.03), which was partially mediated by self-regulation, a strong predictor of METs (Ã =.45, p<.01). The total effect of affect on METs was substantially reduced (Ã =.05, p=.34) when self-efficacy was added as a precursor in the model. Self-efficacy influenced both METs (Ã =.39, p<.01) and affect (Ã =.23, p<.01). Adding environment and social support as predictors of self-efficacy (Ã =.23, p<.01; Ã =.19, p<.01, respectively) further reduced the influence of affect on METs (Ã =.03, p=.63) as environment and social support influenced affect (Ã =.20, p<.01; Ã =.14, p=.02, respectively) and METs (Ã =.15, p=.02; Ã =.21, p<.01, respectively). Conclusion: As in earlier studies of acute affective response to PA, these results provide evidence that anticipatory affect is positively associated with behavioral decision-making related to PA participation. Although increasing an individualâ s self-efficacy for PA should increase their affective association with the behavior, affect may not influence PA decision-making independently of self-efficacy and ecological factors (i.e. environment and social support).Master of Science

Full textAbstract:
Smoking continues to be a significant health problem in the United States and throughout the world. One of the many aspects of the health risks of smoking that have been investigated is the effect of maternal smoking on developing embryos. In particular, exposure of embryos to nicotine is believed to cause attention-deficit/hyperactivity disorder (ADHD) and related problems in children. Both correlational research with humans and experimental research with animals have supported this belief. However, the mechanisms of the effect of nicotine on developing embryos are not fully understood. The zebrafish offers a useful model of the effects of nicotine on developing organisms because its development is fast, well understood, and easily observable. Also, the embryo can be exposed to nicotine without concern for many of the intermediate factors that are present in research with conventional models (e.g., the rat), such as the effect of nicotine on the placenta. This study was an exploratory attempt to establish the zebrafish as a model for the effects of embryonic nicotine (EN) exposure. Zebrafish eggs were exposed to two levels of nicotine during the first eight hours after fertilization. These subjects and a group of controls were measured on three variables at different stages of development: body length, activity level, and avoidance learning. Results showed that EN exposure caused a significant decrease in growth and a significant increase in activity level. Thus, the zebrafish responds to EN exposure in a manner similar to that observed in other models and in humans. Further research on the mechanisms of the effect of EN exposure may be possible using the zebrafish.

Full textAbstract:
ABSTRACTPreoperative Activity Level and Outcomes in Older <&hyphen>¨Adult Cardiac Surgery Patients: A Pilot StudyDon Howard Sorensen Jr.College of Nursing, BYUMaster of SciencePurpose: To assess the relationship between preoperative physical activity levels and health related quality of life on intra- and post-hospital outcomes following scheduled cardiothoracic surgery in older adults.Rationale/Background: Adults age 50 and older tend to accumulate more sedentary time and are less physically active. Sedentary behavior is linked with early morbidity and death and may predispose patients to postoperative complications. Preoperative activity levels and its relationship to surgical outcomes is an underexplored area. Insight on this topic could influence how to optimize interventions prior to surgery to improve outcomes. Methods: Seven participants were fitted with an ActiGraph GT3X+ accelerometer to measure preoperative activity levels for 1 week and complete the RAND Short Form-36 health-related quality of life tool. This process was then supposed to be repeated during the first and last weeks of cardiac rehabilitation (rehab). This information, along with demographics, was then correlated with information pulled from the Society of Thoracic Surgeons database on post-surgical outcomes and the 6-minute walk tests (6MWT) done during rehab. Results: The only statistically significant result was participants who experienced some type of intra-hospital complication also scored low in emotional wellbeing (r = -0.928, p = 0.003) as reflected in the quality of life score. Other findings with p values > 0.05 but <<> 0.1 were noted as <&hyphen>œareas needing further exploration.<&hyphen> Such areas for further exploration included: participants who spent more time in light physical activity reported less role limitations due to physical health (r = 0.864, p = 0.059), higher preoperative activity levels related to higher postoperative 6MWT (r = 0.830, p = 0.082), increased body mass index related to a decrease in postoperatively 6MWT (r = -0.869, p = 0.056). Implications: Exploring the relationship between preoperative activity levels and post-surgical outcomes could provide insight optimizing interventions before surgery to improve surgical success and rehab outcomes.

Beaulieu, Kristine. "The influence of physical activity level on the sensitivity of the appetite control system." Thesis, University of Leeds, 2017. http://etheses.whiterose.ac.uk/20009/.
Full textAbstract:
Background: Based on the non-linear relationship between energy intake and physical activity level demonstrated by Mayer et al. (1956), it has been proposed that there is a dysregulation of appetite at lower levels of physical activity leading to overconsumption, whereas at higher levels of physical activity, appetite control is more sensitive. However, the mechanisms underlying this relationship are not well understood. Objective: This thesis aimed to shed light on the impact of habitual physical activity level in lean individuals and exercise training in individuals with overweight and obesity on homeostatic (physiological) and non-homeostatic (hedonic and eating behaviour traits) appetite processes, including those that initiate and terminate feeding (satiation) and suppress inter-meal hunger (satiety), as well as passive overconsumption (unintentional increase in energy intake with high-energy-density/high-fat foods). Methods: A systematic review was conducted, followed by four experimental studies. The studies employed a multi-level experimental platform that included biological, behavioural and psychological aspects of energy balance including free-living physical activity, food intake, diet composition, food reward (liking and wanting), body composition, energy expenditure and fasting appetite-related peptides. Results: The systematic review revealed a J-shaped relationship between physical activity level and energy intake, corroborating previous findings. Data from the experimental studies indicated that in lean individuals, physical activity did not influence satiation at meals varying in dietary fat content, but moderate to high active individuals showed enhanced satiety with better ability to adjust intake following preloads varying in energy content. Exercise training (12 weeks) in inactive individuals with overweight and obesity improved both homeostatic and non-homeostatic appetite control, which may be mediated by exercise-induced fat loss. Across all studies, physical activity was associated with lower body fat and greater daily energy expenditure, and energy density was positively associated with energy intake and passive overconsumption. Conclusions: This thesis provides confirmatory evidence that physical activity impacts appetite control through a dual-process action expressed through an increased drive to eat from greater energy expenditure, together with enhanced satiety response to food in both lean and overweight/obese individuals. These processes may allow for more accurate matching of energy intake to requirements and a reduction in the risk of overconsumption at higher levels of physical activity.

Circadian rhythmicity, which is driven by a circadian clock, is a property of a biological process that displays an oscillation of approximately 24-hours even in the absence of external time cues. Individual differences in the preferred times of waking, activity and rest (sleep) are known as chronotype or diurnal preference; which arise due to differences in circadian rhythmicity due to the fact that rhythms are not exactly 24-hours. Various polymorphisms of certain genes involved in circadian rhythm generation have been associated with extreme chronotype. Of interest to this study is the PER3 gene as it has a variable number tandem repeat (VNTR) polymorphism in the coding region, which is repeated either four of five times, encoding proteins of different lengths.

Background: Stress and low physical activity (PA) levels are linked to illness. No studies have been found examining them among refugee school students. Aim: Investigate level of PA and perceived stress and the correlation between them among refugee school students. Method: Cross-sectional study with a descriptive, correlative design. Refugee school students completed one questionnaire on perceived stress: Perceived Stress Scale (PSS); and two questionnaires on PA level: Saltin-Grimby Physical Activity Level Scale (SGPALS) and indicator questions for physical activity (SIFA) from the Swedish National board of health and welfare. Results: Altogether 59 students were included. The adult WHO/ FYSS recommended PA levels was met by 55.9%. Median SGPALS was 2 (some light physical activity for at least 4hours/week) out of 4 with 35.6% reported being sedentary during leisure time. Median PSS is 22 out of 40. No significant correlation between SIFA, SGPALS and PSS was found in the population. Conclusion: Over half of the refugee students met the adult WHO/FYSS recommended PA levels and over a third report being sedentary in their leisure time. Initiatives to promote PA among refugee students should be implemented to reduce illness and inactivity.Bakgrund: Stress och låg grad av fysisk aktivitet (PA) är kopplade till ohälsa. Inga studier har påträffats som undersöker stress och PA hos flyktingar som deltar i svenskundervisning. Syfte: Undersöka PA nivå och upplevd stress och sambandet däremellan hos skolelever med flyktingbakgrund. Metod: Tvärsnittsstudie med deskriptiv, korrelerande design. Deltagarna fyllde i frågeformulär om upplevd stress: Perceived Stress Scale (PSS); och två frågeformulär om PA nivå: Saltin-Grimby Physical Activity Level Scale (SGPALS) och Socialstyrelsens indikatorfrågor om fysiskaktivitet (SIFA). Resultat: Totalt 59 elever inkluderades. WHO/FYSS rekommenderade PA nivå för vuxna nåddesav 55,9 procent. Medianen för SGPALS blev 2 (Någon fysisk aktivitet på fritiden under minst 4 timmar per vecka) av 4 med 35,6% som uppgav stillasittande fritid. Medianen för PSS blev 22 av 40. Ingen signifikant korrelation mellan SIFA, SGPALS och PSS påträffades i populationen. Konklusion: Drygt hälften av deltagarna i studien nådde WHO/FYSS rekommenderade PA nivå för vuxna och drygt en tredjedel uppgav att de var stillasittande på fritiden. Initiativ för att främja PA hos skolelever med flyktingbakgrund bör sättas in för att minska ohälsa och stillasittande.

Full textAbstract:
We hypothesized that if normal cells carry a regulator which is inactivated in cancer cells, the transfer of this regulator from a normal cell to a cancerous one should inactivate the telomerase. Available in the laboratory was a panel of mouse/human microcell hybrids, each containing a tagged normal human chromosome fragment integrated into a mouse melanoma (telomerase-positive) background. We screened these hybrids for telomerase activity using both the polymerase chain reaction (PCR)-based telomeric repeat amplification protocol (TRAP) assay and mTERT mRNA amplification.We were able to find a telomerase negative microcell hybrid, B78MC27. Following multiple passages in culture most of the cells undergo senescence; however a small population reactivates telomerase to ensure their survival. The revertant B78MC27-R4, where the human tagged chromosome has been removed, retains telomerase inhibition and also behaves like B78MC27 at later passages. In spite of our efforts, PCR mapping and fluorescence in situ hybridization (FISH) analysis on these hybrids failed to identify the exact region containing the putative repressor. Transfection of a reporter gene (luciferase) under the control of the hTERT promoter into these hybrids confirmed that the telomerase regulation is affecting the hTERT transcription level.
Finally, upon chromosome transfer containing the telomerase repressor into the PC-3M-Pro4GP1 human prostate cancer cell line, we observed hTERT gene transcriptional down-regulation and inhibition of telomerase activity. Thus, telomerase regulation is subject to a dominant negative inhibition likely involving the direct binding of a repressor on the hTERT promoter. The discovery of the natural telomerase regulator could eventually lead to potential cancer therapy, particularly for tumors having short telomeres, as it is seen in prostate cancer.

Full textAbstract:
Approved for public release; distribution is unlimitedControlling the outbreak of epidemic diseases such as influenza has always been a concern for the United States. Traditional surveillance tools such as the ILINet and Virologic provide the Centers for Disease Control and Prevention (CDC) with influenza surveillance statistics at a lag of 1 to 2 weeks. The CDC requires a tool that can forecast the level of influenza activity. The rise in the popularity of social media websites such as Flickr, Twitter and Facebook has transformed the web into an interactive sharing platform. The huge amount of generated unstructured data has become an invaluable source for detecting patterns or novelties. This research explores the correlation between Twitter messages (tweets) and CDC ILI and Virologic surveillance data. Using 17 months of tweets, regression models are developed to predict influenza-related statistics. The proposed approach aggregates the weekly frequencies of hand-chosen words that are indicative of an influenza attack using separate predictor variables. The predictions generated by the best models are found to have a Pearson’s correlation coefficient of 0.900 (95% CI: 0.732, 0.965) and 0.833 (95% CI: 0.574, 0.940) against the CDC ILI surveillance data and CDC Virologic surveillance data, respectively.

Full textAbstract:
It has been suggested that moderate exercise contributes to protection against the development of chronic diseases by anti-inflammatory mechanisms that include elevations of anti-inflammatory cytokines and also reduction of the expression of Toll- Like Receptors (TLRs). However, prolonged strenuous exercise has been shown to reduce the function of some immune cells, decrease virus protection and consequently may account for the reason athletes appear more vulnerable to catching Upper Respiratory Tract Infections (URTI). Although it has been proven that some exercise is better than no exercise, it is not clear yet what is the right amount of exercise to elicit beneficial immune responses and to help prevent the development of diseases. Therefore, the general aim of the studies in this thesis was to evaluate the impact of different types of exercise on monocyte TLR expression in participants with different fitness levels. It was found that different acute exercise protocols elicit different changes in TLR2 and TLR4 expression, where an acute bout of strenuous exercise reduced TLR4 expression for a few hours after the completion of the exercise (Chapter 5); however, short two bouts of exhaustive exercise separated by 2 hours did not change TLR4 expression (Chapter 6). In addition, changes in TLR4 expression were related to sex and the physical activity level of the participants (Chapter 4), and should therefore be considered separately when analysing TLR4 expression. Furthermore, high-intensity intermittent training improves participants' aerobic capacity and modifies the monocyte subpopulation concentration in the blood, with no changes in TLR4 expression. Further research needs to be done in this area to achieve a conclusive finding about changes in TLR4 expression and monocyte subsets after different training protocols, and possible relationships to cytokine production.

Full textAbstract:
OBJECTIVE: This cross-sectional study investigated insulin resistance (IR) variation across physical activity (PA) levels in U.S. adults. METHODS: MET-minutes were utilized to quantify PA using 2 methods: 4 categories were based on relative MET-minutes, and 5 were based on U.S. PA guidelines. IR was indexed using the homeostatic model assessment (HOMA). Effect modification was tested by dividing waist circumferences into sex-specific quartiles, and then evaluating the relationship between PA and HOMA-IR within each quartile separately. RESULTS: Relative PA was associated with HOMA-IR after controlling for demographic and demographic and lifestyle covariates (F = 11.5, P < 0.0001 and F = 6.0, P = 0.0012, respectively). Adjusting for demographic and demographic and lifestyle covariates also revealed relationships between guideline-based PA and HOMA-IR (F = 8.0, P < 0.0001 and F = 4.9, P = 0.0017, respectively). Controlling for waist circumference with the other covariates nullified the relationship between PA and HOMA-IR. Effect modification testing showed that when the sample was delimited to adults with extra-large waists (Quartile 4), relative (F = 5.6, P = 0.0019), and guideline-based PA (F = 3.7, P = 0.0098) and HOMA-IR were related. PA and HOMA-IR were not related within the other quartiles. CONCLUSION: High levels of PA may play a meaningful role in glucose and insulin metabolism in those with abdominal obesity, but not in adults with smaller waists.

The steady raise in childhood obesity is a major public health problem nationally and globally. Childhood obesity is primarily caused by an imbalance between caloric intake and caloric expenditure. The increase in childhood obesity rates over the past 3 decades suggested involvement of environmental and behavioral factors in the obesity epidemic. While childhood obesity is considered a public health crisis in the United States, only limited research is available about the potential impact of neighborhood-level factors such as access to healthy food, neighborhood safety, and risk-free outdoor playgrounds. The purpose of this study was to examine if any relationships existed between childhood obesity and type of diet, level of physical activity, and neighborhood-level risk factors and childhood obesity. This study accessed the California Health Interview Survey (CHIS) 2009-2014 data sets. Chi-square tests and multivariate logistic regression were used to evaluate the associations between independent and dependent variables. The Wald test was used to assess the effects of each individual predictor, while adjusting for other predictors. The findings of this study showed no significant associations between childhood obesity and neighborhood safety; parental educational level; presence of parks, playgrounds, or open spaces; neighborhood walkability; neighborhood safety and support; and gender. Low physical activity levels, however were a significant risk factor for increase obesity. This study may lead to positive social change, enhancing individual lives and whole communities, by drawing the awareness of public health officials and policy makers to the importance of neighborhood factors associated with high body mass index.

Connecting power-monitoring data to everyday human activities is an important aspect of promoting energy-saving behavior. This thesis proposes an activity level power monitoring system (ALPS) that disaggregates energy consumption based on human activities (e.g., cooking and watching TV). This thesis reports the design and implementa- tion of the ALPS, and evaluated the proposed system by deploying 57 power monitoring nodes in three homes with nine participants over a 4 week period and collected over 1200 household energy-consuming activities. Results show that the proposed system successfully recognizes 92.97% of energy consuming activities, and achieves an accuracy of 95.55% in activity level energy monitoring.

Workflow management system (WFMS) enables the enterprise processes to be automatic, helping companies reduce costs, improving work efficiency, monitoring the work of the implementation and evaluating performance. With the transactions of business increase rapidly and the complexity of workflow enhance quickly, the activities in the workflow emergence more and more frequent time duration, the time duration make the schedule of activities can not be expected to complete and bring the business’ skill into full play. Therefore, this study mines out the activities of abnormal time duration from the historical records of the workflow, providing these to business executives as the basis for improvement of workflow. Purpose of this paper is to accurately find all types of the time duration occurring in workflow, so we develop a Fuzzy Anomalous Duration Algorithm (FADA), based the important activity properties in the workflow to estimate the proper executive time of activities with fuzzy theory. This algorithm can more able to reflect the actual status of the workflow, and effectively identify all types of the time duration. We use the global logistics process of the stone industry to validate the accuracy of this algorithm, and compared the algorithm’s time duration result with Activity-based Algorithm for Mining Temporal Outlier (ABTO). The results show that this algorithm can correctly find all types of time duration, and the accuracy rate is much higher. The time duration results of this algorithm can be interpreted in the enterprise on a much higher proportion than ABTO, and more able to respond to the actual situation of workflow operations. This paper’s algorithm (FADA) makes some improvements on the fuzzy inference system; it leaves out the step that needs experts’ judge. And it increases the developers’ flexibility in the design of fuzzy inference system.

Sufficient physical activity can reduce the incidence of chronic diseases, obesity and depression. Nowadays, however, many people live without sufficient physical activity, and do not aware whether their daily activity is enough or not. If there is a system to record outdoor activities and remind the user whether their activity is sufficient or not, it will be helpful and easy to maintain sufficient physical activity in daily life. Activity level was used to quantify physical activity, and assist user to planning sport project. Therefore, our purpose is to use wearable sensor, as a sensing and reminding device cooperating with wireless system to help user maintain their physical activity. Before recording and reminding service, real-time activity recognition was the first step. In this work, we present a real-time activity recognition system by using wearable sensor. The accelerometer mounted in the front waist and back waist sensing, transmitting data to computer. The time series of raw data will be preprocess through the aggregation technique of jumping window. The raw data will be separated as gravity signal and body acceleration. Through feature extraction and threshold classification, real-time activity recognition is achieved. Finally, activity recognition can achieve 90% accuracy and activity level can achieve 80% accuracy. As a result, the system can apply for activity recognition and activity level.

Existing approaches for egocentric activity recognition mainly rely on a single modality (e.g., detecting interacting objects) to infer the activity category. However, due to the inconsistency between camera angle and subject''s visual field, important objects may be partially occluded or missing in the video frames. Moreover, where the objects are and how we interact with the objects are usually ignored in prior works. To resolve these difficulties, we propose to leverage multiple mid-level representations to improve egocentric activity classification accuracy. Specifically, we aim at utilizing multimodal representations (e.g., background context, objects manipulated by a user, and motion patterns of hands) to compensate the insufficiency of a single modality, and jointly consider what, where, and how a subject is interacting with. To evaluate the method, we introduce a new and challenging egocentric activity dataset (ADL+) that contains video and wrist-worn accelerometer data of people performing daily-life activities. Our approach significantly outperforms the state-of-the-art method on the ADL dataset (i.e., 36.8% to 46.7%) and our ADL+ dataset (i.e., 32.5% to 60.0%) in terms of classification accuracy. In addition, we also conduct a series of analyses to explore relative merits of each modality to egocentric activity recognition.

The main purposes of study were to understand and compare cardiorespiratory fitness (VO2max, FVC, FEV1, AT) and physical activity of different obese level children. It also attempted to give a further study on the relationship between physical activity and cardiorespiratory fitness. 133 boys, aged 4-11 years were selected including non-obese(75), overweight(25), and obesity(33). One-way ANOVA and Hierarchical Regression were used to analyze data. The results indicated that: 1. The non-obese boys’ cardiorespiratory fitness is better than the obese boys significantly . 2. There is no significantly difference among different obesity boys’ physical activity level. 3. The physical activity level showed revealed a direct relationship with FVC and FEV1among different obesity children. 4. The physical activity level showed no significant difference in VO2max and AT among different obesity children. In conclusion, Obesity has become a serious issue not only affecting personal health, but also costing the healthcare resources of the society. To improve the public health from obesity, the best way is to prevent childhood obesity throughout the child growth, especially during the puberty. For this, the solution lies in maintaining the cardiorespiratory fitness by balanced diet and appropriate physical activity during the children’s growth and development.

Internet addiction disorder (IAD) means pathological use Internet that results in the impairment on familial, academic, social, and occupational functions. Previous IADs’ attentional bias studies more focused on dependence level, but ignored activity type and inhibitory ability. The current study examined whether activity type and dependence level can affect the IADs’ attentional bias after controlling for their inhibitory abilities. We recruited participants engaging in Counter Strike (CS) and Facebook (FB). According to dependence level and type activity, all participants were divided into four groups: CS IADs, FB IADs, CS non-IADs and FB non-IADs. Each participant had to complete the standard Stroop task (to assess inhibitory ability) and the addiction Stroop task (to assess attentional bias) in sequence. In the addiction Stroop task, the CS IADs showed significantly longer reaction time to CS-pictures than the FB IADs; the FB IADs had greatly longer reaction time to FB pictures than to other pictures. The findings suggested that the IADs exhibited activity-specific attentional bias. On the other hand, in the standard Stroop task, the IADs revealed longer naming latencies than the non-IADs. The findings indicated that IAD had dysfunction in inhibitory ability. In conclusion, both activity type and dependence level can affect IADs’ attentional bias after controlling for inhibitory ability. Both dependence level and type activity play critical role for IAD development.
