Résumé :
In today’s digitalized world, smartphones are the devices which have become a basic and fundamental part of our life. Since, these greatest technology’s appearance, an uprising has been created in the industry of mobile communication. These greatest inventions of mankind are not just constricted for calling these days. As the capabilities and the number of smartphone users increase day by day, smartphones are loaded with various types of sensors which captures each and every moment, activities of our daily life. Two of such sensors are Accelerometer and Gyroscope which measures the acceleration and angular velocity respectively. These could be used to identify the human activities performed. Basically, Human Activity Recognition is a classifying activity with so many use cases such as health care, medical, surveillance and anti-crime securities. Smartphones have wide variety of applications in various fields and can be used to excavate different kinds of data which provide accurate insights and knowledge about the user's lifestyle. Nowadays creating lifelogs that is a technology to capture and record a user's life through his or her mobile devices, are becoming very important task. An immense issue in creating a detailed lifelog is the accurate detection of activities performed by human based on the collected data from the sensors. The data in the lifelogs has strong association with physical health variables. These data are motivational and they identify any type of behavioral changes. These data provide us the overall measure of physical activity. In this project, we have analyzed the smartphone sensors produced data and used them to recognize the activities performed by the user.

Résumé :
Because the number of elderly people is predicted to increase quickly in the upcoming years, “aging in place” (which refers to living at home regardless of age and other factors) is becoming an important topic in the area of ambient assisted living. Therefore, in this paper, we propose a human physical activity recognition system based on data collected from smartphone sensors. The proposed approach implies developing a classifier using three sensors available on a smartphone: accelerometer, gyroscope, and gravity sensor. We have chosen to implement our solution on mobile phones because they are ubiquitous and do not require the subjects to carry additional sensors that might impede their activities. For our proposal, we target walking, running, sitting, standing, ascending, and descending stairs. We evaluate the solution against two datasets (an internal one collected by us and an external one) with great effect. Results show good accuracy for recognizing all six activities, with especially good results obtained for walking, running, sitting, and standing. The system is fully implemented on a mobile device as an Android application.

Résumé :
STATEMENT OF PROBLEM: Physical activity (PA) is a critical determinant of long term health and is necessary for the prevention of youth onsetadult diseases. It is recommended that all youth accumulate at least 60+ min of moderate to vigorous physical activity (MVPA) most days of the week in bouts lasting at least 10 min. PURPOSE: To evaluate the PA patterns of Missoula youth in order to make better recommendations for PA interventions for a wellness policy. METHODS: 324 elementary and middle school students from 5 schools wore accelerometers on their wrists for 5 days. The data were converted to activity energy expenditure (AEE) and also evaluated for single min and bouts of activity lasting at least 10 min of MVPA daily, in- versus out-of-school, and during sport, physical education (PE), and recess. Grade and gender differences were also assessed. RESULTS: The data show better than national averages in daily min of MVPA, with 70% of all students meeting the recommendation in 10 min bouts. Students showed low levels of MVPA during PE, recess, and sport. Sport was responsible for the highest accumulation of MVPA, followed by recess and then PE in both 1 and 10 min bouts. There was a drop in MVPA in both genders as grade level increased (both in and out of school), with more MVPA in single and 10 min bouts occurring out of school than in school. Males showed higher levels of MVPA than females during PE in 1 min bouts, recess in 1 and 10 min bouts, and in school in 1 and 10 min bouts. When scaled for body weight, genders did not differ in AEE. CONCLUSIONS: These data suggest an overall healthy youth PA environment in Missoula. However, the 30% of students not meeting the recommendations for health in 10 min bouts are still of concern. Interventions could focus on encouraging slight increases of MVPA during PE, sport, and recess, especially at the middle school level. Increasing out of school MVPA is also necessary to make the biggest impact due to already overburdened school systems.

Résumé :
Osteoporosis causes bone to become fragile. Pharmacological treatments of osteoporosis are burdened with adverse effects and increase bone mineral density (BMD) only between 1% and 15% depending on the drug and time used. Thus non pharmacological treatments are needed to complement pharmacological ones. Physical activity is a non pharmacological treatment of osteoporosis and is essential for maintaining bone health at any age. However, physical activities have been identified to produce a modest improvement of spinal strength or just preserve it. In addition, it is not known how much exercise is optimal and safe for people with spinal osteoporosis. Most research employs conflicting definitions of physical activity and measure the effect of exercise on BMD alone instead of combining it with measurements of three dimensional bone strength. There is the need to offer a technique to measure the effect of physical activity on the overall strength of the spine, not only on its bone mineral content. Vibration transmissibility is a measurement of the mechanical response of a system to vibration expressed as stiffness or damping, thus offering a variable that represents structural strength. It can be employed to measure the mechanical response of the human spine during physical activity by attaching inertial sensors over the spine. However, it has not been employed to characterize the way vibration is transmitted through the osteoporotic spine during physical activity. Understanding the effects of osteoporosis and ageing on vibration transmission is important since such effects are related to the stiffness of the spine and thus very likely to the incidence of vertebral fractures. It is also often recommended that fast walking is beneficial to the bone, yet it is not known if fast walking affects the mechanical response of the spine of people with osteoporosis. The aims of this study were (1) to evaluate the feasibility of employing inertial sensors and a skin correction method to measure vibration transmission through the spine during physical activity (2) to characterize the transmission of vibration in the lumbar and thoracic spines of people with and without osteoporosis during physical activities, (3) to characterize the effect of osteoporosis on vibration transmissibility at levels of the thoracic spine which are known to fracture and (4) to investigate the effects of fast walking on vibration transmissibility. 100 young and healthy and older volunteers with and without osteoporosis were recruited. Participants were asked to perform straight walking, stair negotiation and turning while having inertial sensors attached to the skin over the spinous process of the first sacral (S1), twelfth (T12), eighth (T8) and first thoracic vertebrae (T1). Vibration transmissibility was calculated as the square root of the acceleration of the output (T12 for the lumbar and T1 for the thoracic spine) over the input (S1 for the lumbar and T12 for the thoracic spine) in the frequency spectrum. Vibration transmissibility was corrected for the movement of the skin-sensor interface and for the inclination of the sensor over the spine of every subject. All physical activities were performed at self selected normal and fast walking speeds. Lumbar and thoracic curvatures were determined with an electromagnetic device and BMD was measured through quantitative ultrasound. Skin measurement of transmission of vertical vibration is feasible with the inertial sensors and correction method presented. Vibration transmissibility through the human spine is significantly different between dissimilar physical activities and frequency dependent. Ageing significantly alters the vibration transmissibility of the spine. Osteoporosis has a minimal effect on vibration transmissibility of the spine. The effect of ageing and osteoporosis are frequency dependent. Older lumbar spines may receive greater stimulation than young and healthy ones, whereas older thoracic spines may receive lower stimulation during fast walking. There are significant differences in vibration transmissibility between lumbar and thoracic spines. A percentage of vibration transmission of the lumbar and thoracic spines is determined by their curvatures. This thesis has provided a technique that future research can employ to correlate vibration transmissibility with mechanotransduction signals in bone as well as volumetric bone health measurements and the risk of vertebral fractures. Until then it will be possible to prescribe physical activity taking into account individual capabilities, bone strength and differences in mechanical response between lumbar and thoracic sections.

Résumé :
In rodent models of human behaviour, physical activity builds stress resilience. In contrast, human studies physical activity and stress resilience have been limited, and when investigated, provided mixed results. These inconsistencies may be due to the ambiguous use of the term stress resilience in human studies, making it difficult to quantify. Therefore, I aimed to assess the effect of physical activity on stress resilience in humans, after first evaluating operational definitions of stress resilience. Initially, I evaluated the use of stress resilience across the literature to provide a definition that is consistent with the research base (Chapter 2). I subsequently defined stress resilience as an active process of adapting to unpredictable and uncontrollable stimuli. In Chapter 3, I systematically reviewed measures previously used to capture stress resilience in humans, including trait-based questionnaires, as well as affective and cardiorespiratory responses to stressful conditions. In Study 1 (Chapter 4) of this dissertation, I then assessed the convergent validity of these stress resilience measures , including the Brief Resilience Scale and the Connor-Davidson Resilience Scale, as well as various responses (i.e., affective balance, systolic blood pressure, rate pressure product, and multiple indices of heart rate variability) to three stressor conditions (i.e., no stress, auditory startles, and stressful video clips). Results of Study 1 indicated that no measure captured all elements of stress resilience, although some indices of heart rate variability were related to changes in affective balance and systolic blood pressure was related to the Brief Resilience Scale. Across two studies, I then evaluated the effect of physical activity on stress resilience using the measures from Study 1. Through a cross-sectional study (Study 2, Chapter 5), I found no difference between active participants (n = 16) and less active participants (n = 14) across stress resilience measures. Additionally, in Study 3 (Chapter 6), I found that an 8-week moderate physical activity intervention had no effect on these stress resilience measures in 14 participants from desk-based occupations. I did, however, find an increase in mood and reduction in systolic blood pressure post-intervention, compared to pre-intervention scores. I also discussed the feasibility of various recruitment techniques, intervention purity and adherence, as well as stress resilience measurement protocols for future intervention studies. Overall, this dissertation has provided a critical evaluation of the use and measurement of stress resilience, with findings indicating that physical activity may not enhance stress resilience in humans. I discuss differences in my findings, compared to rodent research, including the potential effects of environment enrichment and increased severity of measurement protocols in animal models. I also discuss limitations of stress resilience conceptualisation and provide suggestions for future research to navigate these challenges.

Résumé :
Executive function (EF), that shows rapid development in the preschool years, is foundational for cognitive development. Previous research has found aspects of physical development including gross motor skills and physical activity to be related to EF. However, evidence for these relationships in the preschool years, as well as in low- and middle-income countries is lacking. Therefore, this study aimed to investigate the relationships between EF (and related components of cognitive development) with physical activity and gross motor skills (GMS) in a sample of preschool children from urban and rural low-income settings in South Africa. Cognitive and physical outcomes were measured in a sample of preschool children (N=129; Mage = 50.7±8.3 months; 52.7% girls) from urban (Soweto) and rural (Bushbuckridge) low-income settings in South Africa. Cognitive components included EF, self-regulation (Early Years Toolbox, EYT), attention (adapted visual search task) and school readiness (Early Childhood Development Criteria Test). Physical outcomes included objectively measured physical activity (accelerometry), gross motor skills (Test for Gross Motor Development 2) and anthropometric measurements (height and weight). On average, children from both settings showed higher than expected scores for EF and self-regulation (based on Australian norms for the EYT), adequate gross motor proficiency and high volumes of physical activity (M total physical = 476 minutes per day). In contrast, a high proportion of children, particularly in the rural setting, demonstrated below average scores for school readiness. Investigations into the relationships revealed that EF was positively associated with self-regulation, attention and school readiness. Positive associations were also found between GMS and physical activity and, and physical activity and body mass index (BMI). And finally, that GMS, but not physical activity, was positively associated with all components of cognitive development. This study is the first to provide evidence for the importance of EF and the link between motor and cognitive development in preschool children from South African, low-income settings. Another key finding was that there may be factors promoting early EF skills in these settings but that these skills, although associated, are not transferring to school readiness. The lack of (or negative) associations between physical activity and cognition presents another key finding, further research is needed to identify whether there are specific amounts and types of physical activity that specifically benefit cognitive development.

Pedometers have been demonstrated as a practical tool for measurement and motivation of ambulatory physical activity, typically providing information on volume of steps/day. Recent developments in steps/day research have, however, emphasised the importance of intensity-based steps as part of steps/day recommendations. Such steps/day recommendations are also directed towards current physical activity guidelines, so as to provide further options for achieving guidelines. To complement these developments in steps/day recommendations, technological advancements in pedometry afford the opportunity to provide information on intensity-based steps/day. We therefore use this application to provide further insight into the association between pedometer-based physical activity and fitness and health outcomes. Particular reference is made to intensity-based steps/day, through a series of studies.

Résumé :
Human motion is complex and enables people to interact with the environment and conduct their daily activities. However, the physical activity levels of people living in modern society has reduced compared to ancestral environments, where people needed to undertake high rates of physical activity in order to pursue their prey and escape predators. In contemporary society, people living in rural areas undertake less vigorous activity due to mechanisation and industrialisation. In addition, sedentary behaviour has increased due to urbanisation, despite the fact that the health benefits of promoting general human movement through physical activity have been well established. The amount of physical activity of people living in urbanised areas also differs from those in rural areas. However, data related to physical activity are specifically lacking in developing countries. The aim of this thesis was to investigate genetic (heritability) and environmental contributions to musculoskeletal motion and physical activity in Mongolian adults. Chapter Two showed that too few studies have investigated the heritability of musculoskeletal motion. Chapter Three and Four found strong environmental contributions to light intensity physical activity, sedentary behaviour, and lumbar motion control, whilst high heritability was noted for higher intensities of physical activity and lumbar posture. Chapter Five identified that health benefits were the top motivator for physical activity, regardless of residential region, but barriers were region specific. Chapter Six found deceased physical activity along with prolonged sitting was negatively associated with lumbar motion, suggesting that increasing physical activity may promote lumbar motion. Incorporating health benefits as the top motivator into a physical activity intervention, as well as addressing region-specific barriers, may be beneficial in promoting individuals to be active in Mongolia.

Résumé :
Rapid advancement in the field of Artificial Intelligence, to be more specific in Machine Learning and Nanotechnology, strengthens hopes to better understand human mind. Ubiquitous Computing helped in the creation of intelligent environments pervaded by these visible and invisible devices, which are affecting and improving all aspects of human life. So, as a consequence, smart environments work on the behalf of humans for ease of comfort. The ultimate goal is to monitor humans without any awareness by them of computer interaction. The understanding of how humans will interact and make use of such systems is however largely unresolved and often not addressed collectively from both scientific and medical aspects in current research. A key to understanding such systems and their use is the observation that humans implicitly interact with their environment. The task of making this context information available to components in computer systems has become a prerequisite to move forward in human- computer interaction. Context awareness or more specifically how to create applications that are context aware is a central issue to Ubiquitous Computing research. Such research raises questions on context acquisition, context representation, distribution and abstraction, as well as programming paradigms, development support, and implications on human-computer interaction in general. The aim of this thesis is to develop part of a ubiquitous care system to monitor elderly basic daily life activities; stand, sit, walk, lay and transitional activities. This thesis investigates the use of a wearable sensor (tri-axial accelerometer) to develop and evaluate the activity classification scheme with reliable accuracy in the real-world situations. The recognition of these activities is challenging because activities with similar posture are hard to discriminate (e.g. stand and sit). Moreover, this high similarity among activities is not uniform throughout the whole dataset which raises the question of how much training data would be required. Furthermore, the activity classification schemes proposed in literature are typically subject-independent; however there is lack of evidence that such subject-independent schemes have been successfully validated with elderly in uncontrolled situations.

Résumé :
Cross-sectional evidence associates breakfast omission with negative health outcomes. The present work aimed to examine if these cross-sectional associations have a causal component, by conducting randomised control trials in healthy humans. It was established using lean individuals that there are divergent hormonal responses to morning feeding and fasting, although increased energy intake at lunch following fasting incompletely compensated for breakfast intake. Hormonal and subjective appetite responses in the afternoon did not consistently provide evidence for increased hunger following fasting. In the same participants assigned to a 6-week free-living intervention of either 700 kcal pre 11:00 or fasting until 12:00 daily, it was found that energy intake was greater in those assigned breakfast consumption, but that physical activity was also greater than those fasting. Cardiovascular risk factors and measures of metabolic control were largely unaffected by either intervention. There was no adaptation of acute metabolic/hormonal responses to feeding following either intervention. In obese individuals, similar patterns of results were obtained for the hormonal and metabolic responses to acute feeding and fasting, but with no compensation for breakfast intake at lunch. Results from the free-living intervention demonstrated no difference in energy intake between groups or physical activity over the entire day, but greater energy expenditure during the morning in those consuming breakfast. Markers of cardiovascular health and metabolic control were generally not differently affected by either intervention. Neither intervention caused adaptation of the acute hormonal and metabolic responses to feeding. In summary, acute morning fasting does not cause complete compensation for breakfast intake at lunch, or result in greater hunger throughout the afternoon. Daily morning fasting does not affect acute responses to feeding or cause increased energy intake or weight gain relative to self-selected breakfast consumption, but seems to limit physical activity in lean, and to a lesser extent, in obese individuals.

Texte intégral
Résumé :
The group of scientists that make up the Intergovernmental Panel on Climate Change found in 2007 that the warming of Earth’s climate is unequivocal and largely due to human activity. Earth’s climate has changed in the past, though the recent magnitude and pace of changes are unprecedented in human existence. Recent decades have been warmer than at any time in roughly 120,000 years. Most of this warming can be attributed to anthropogenic activity, primarily burning fossil fuels (coal, oil and natural gas) for energy. Burning fossil fuels releases carbon dioxide and other heat trapping gases, also known as greenhouse gases, into the atmosphere. This warming cannot be explained by natural causes (volcanic and solar) alone. It can be said with confidence that human activities are primarily responsible for the observed 1.5 ˚F increase in 20th century temperatures in the Pacific Northwest. A warmer climate will affect this state substantially. In 2007, the Oregon State Legislature charged the Oregon Climate Change Research Institute, via HB 3543, with assessing the state of climate change science including biological, physical and social science as it relates to Oregon and the likely effects of climate change on the state. This inaugural assessment report is meant to act as a compendium of the relevant research on climate change and its impacts on the state of Oregon. This report draws on a large body of work on climate change impacts in the western US from the Climate Impacts Group at the University of Washington and the California Climate Action Team. In this report, we also identify knowledge gaps, where we acknowledge the need for more research in certain areas. We hope this report will serve as a useful resource for decision-makers, stakeholders, researchers and all Oregonians. The following chapters address key sectors that fall within the biological, physical and social sciences in the state of Oregon.

Economic Valuation of the Ecosystem Services of the Mesoamerican Reef, and the Allocation and Distribution of these Values.

Texte intégral
Résumé :
Coral reefs are one of the most diverse and valuable ecosystems on Earth. The Mesoamerican Reef contains the largest barrier reef in the Western Hemisphere. However, its health is threatened, so there is a need for a management and sustainable conservation. Key to this is knowing the economic value of the ecosystem. “Mainstreaming the value of natural capital into policy decision-making is vital” The value of environmental and natural resources reflects what society is willing to pay for a good or service or to conserve natural resources. Conventional economic approaches tended to view value only in terms of the willingness to pay for raw materials and physical products generated for human production and consumption (e.g. fish, mining materials, pharmaceutical products, etc.). As recognition of the potential negative impacts of human activity on the environment became more widespread, economists began to understand that people might also be willing to pay for other reasons beyond the own current use of the service (e.g. to protect coral reefs from degradation or to know that coral reefs will remain intact in the future). As a result of this debate, Total Economic Value (TEV) became the most widely used and commonly accepted framework for classifying economic benefits of ecosystems and for trying to integrate them into decision-making. This report estimates the economic value of the following goods and services provided by the MAR's coral reefs: Tourism & Recreation, Fisheries, Shoreline protection. To our knowledge, the inclusion of non-use values in the economic valuation of the Mesoamerican Barrier Reef System is novel, which makes the study more comprehensive.

Spotlight on social equity, finance and scale : Promises and pitfalls of nature-based solutions. Stockholm Environment Institute, juin 2021. http://dx.doi.org/10.51414/sei2021.011.

Texte intégral
Résumé :
Human activity has modified and deteriorated natural ecosystems in ways that reduce resilience and exacerbate environmental and climate problems. Physical measures to protect, manage and restore these ecosystems that also address societal challenges in sustainable ways and bring biodiversity benefits are sometimes referred to as “nature-based solutions” (NBS). For example, reducing deforestation and restoring forests is a major opportunity for climate mitigation, while protecting or restoring coastal habitats can mitigate damage to coastal areas from natural hazard events, in addition to potentially providing co-benefits related to livelihood, recreation, and biodiversity. There is now an impetus to shift towards greater deployment of nature-based solutions. Not only do they offer an alternative to conventional fossil fuel-based or hard infrastructure solutions but, if implemented correctly, they also hold great promise for achieving multiple goals, benefits and synergies. These include climate mitigation and resilience; nature and biodiversity protection; and economic and social gains. 2020 saw an explosion in publications about NBS, which have contributed to filling many of the knowledge gaps that existed around their effectiveness and factors for their success. These publications have also highlighted the knowledge gaps that remain and have revealed a lack of critical reflection on the social and economic sustainability aspects of NBS. Building on these gaps, we decided to launch this mini-series of four briefs to provoke a more nuanced discussion that highlights not only the potential benefits, but also the potential risks and trade-offs of NBS. The purpose is not to downplay the importance of NBS for biodiversity, ecosystems, and coastal mitigation and adaptation, but to ensure that we establish a dialogue about ways to overcome these challenges while leaving no one behind.

Résumé :
In early June 2021, representatives from a number of CNI member institutions gathered for the third in a series of Executive Roundtable discussions that began in spring 2020, during the early days of the COVID-19 emergency. The conversations were intended to inform our understanding of how the pandemic had impacted the research enterprise and to share information about how institutions were planning to shape investments and strategies surrounding the research enterprise going forward. Previous Roundtables were held in April and September 2020 and reports from those conversations are available from http://www.cni.org/tag/executive-roundtable-report. As with the earlier Roundtables on this topic, June participants primarily included senior library administrators, directors of research computing and information technology, and chief research officers from a variety of higher education institutions across the US and Canada; most participating member institutions were public universities with high research activity, though some mid-sized and private institutions participated as well. The June Roundtable took place in a single convening, supplemented by an additional conversation with a key institution unable to join the group meeting due to last-minute scheduling conflicts. As before, we urged participants to think about research broadly, encompassing the humanities, social sciences, and fieldwork activities, as well as the work that takes place in campus laboratories or facilities shared by broader research communities; indeed, the discussions occasionally considered adjacent areas such as the performing arts. The discussion was wide-ranging, including, but not limited to: the challenges involving undergraduate, graduate and international students; labs and core instrumentation; access to physical collections (libraries, museums, herbaria, etc.) and digital materials; patterns of impact on various disciplines and mitigation strategies; and institutional approaches to improving research resilience. We sensed a growing understanding and sensitivity to the human toll the pandemic has taken on the research community. There were several consistent themes throughout the Roundtable series, but shifts in assumptions, planning, and preparation have been evident as vaccination rates have increased and as organizations have grown somewhat more confident in their ability to sustain largely in-person operations by fall 2021. Still, uncertainties abound and considerable notes of tentativeness remain, and indeed, events subsequent to the Roundtable, such as the large-scale spread of the Delta variant of COVID-19 in the US, have eroded much of the confidence we heard in June 2021, though probably more around instructional strategies than the continuity of the research enterprise. The events of the past 18 months, combined with a growing series of climate change-driven disruptions, have infused a certain level of humility into institutional planning, and they continue to underscore the importance of approaches that emphasize resilience and flexibility.
