Athletes use a wide range of interventions to promote recovery from strenuous exercise, but few data are available regarding the efficacy of such practices. OBJECTIVE: To examine the effectiveness of commonly used interventions [Rest, light exercise (AR), contrast therapy (CT) and cryotherapy (CR)] during recovery between bouts of intense exercise. We tested the hypothesis that hydrotherapy interventions (CT and CR) would induce favorable physiological and/or psychological alterations such that performance would be improved versus AR and Rest. METHODS: In Study I, 12 active men (25-35 yrs; VO2peak = 46±3 ml·kg-1·min-1; mean±SD) performed 5 consecutive days of HI exercise (4-6 bouts x 30 sec 'all out' Wingate Tests, with 4-min recovery, each day). After each training session, subjects either rested for 20 min (CON, n=6) or completed a CT protocol (n=6) that consisted of alternating cold (10°C) and hot (40°C) tubs using a 4x2:3 min ratio. Performance measures [Peak (Wmax) and mean (Wmean) power, VO2peak, and a 250 kJ Time Trial (TT)] were assessed before and after the HIT. In Study II, 9 active men (29±6 yr, VO2peak = 44±8 ml·kg-1·min-1) performed 3 exercise trials separated by 1 wk. Each trial consisted of 3 x 50 KJ time trials(~100-120%VO2peak) with a different 20-min recovery period [CON, AR (cycling@ SOW) or CR (cold tub@ 10°C)] between rides each week. Venous blood samples were obtained after each recovery period, and analyzed for lactate, interleukin-6, neutrophils, and lymphocytes. Questionnaires designed to assess exercise preparedness were also completed daily in both studies. RESULTS: In Study I, Wmax and TT performance improved after 5 d of HI exercise (time effect, P<0.05), but there were no differences between groups (Wmax-CT: Post: 1310±45 vs Pre: 1215±86; CON: Post: 1343±54 vs Pre: 1220±74 W: TT-CT: Post: 15.8±0.6 vs Pre: 16.7±0.7; Rest: Post: 18.1±1.0 vs Pre: 18.8±1.2 min, means±SEM). In Study II, TT performance averaged 118±10 sec for bout 1 and was 8% and 14% slower during bouts 2 (128±11 sec) and 3 (134±11 sec), respectively, with no difference between treatments (Time effect, P≤0.05). Blood lactate was lower after AR compared to CR and Rest, and neutrophils and lymphocytes were higher and lower respectively (P≤0.05), after CR (8.7±1.3 and 1.4±0.2 x 109cells/L) versus AR (7.1±1.0 and 1.6±0.1) and Rest (6.7±0.7 and 1.6±0.1). With respect to the psychological measurements, the CT and CR groups in both studies reported feeling more revitalized after each treatment session and greater preparedness for subsequent exercise (Treatment effect, P≤.05). CONCLUSIONS: Exercise performance during repeated bouts of intense cycling was not influenced by the type of recovery intervention employed, either during a single session or over the course of a 5 d training session. CR caused greater perturbations in blood immune markers and most notably, hydrotherapy interventions created the perception that subjects were better prepared for subsequent exercise. / Thesis / Master of Science (MS)

Background: Sleep is commonly disrupted following pediatric concussion. Recently, post-concussion sleep quality has been identified as a potential factor that may influence recovery length. However, few studies have examined this relationship using objective sleep measures in a pediatric population. Nor, have any studies examined the trajectory of objective sleep parameters after pediatric concussion. Objectives: The purpose of this thesis is to: 1) Provide a review of current literature regarding pediatric concussion, healthy sleep quality, and sleep quality in the context of concussion and recovery from concussion; 2) Examine how objective sleep outcomes are affected and change post-concussion in children and adolescents; 3). Explore how post-concussion sleep quality parameters are related to length of recovery, quality of life (QOL), and depression symptomatology; and 4) Discusses the results from the two studies in the context of current literature and of each other. Methods: Sleep quality was inferred from the outcomes of five objective sleep parameters. Sleep parameters were measured using actigraphy in children and adolescents with concussion following return to school (RTA) and return to activity (RTA) protocols. Sleep data during the initial 4 weeks of recovery was assessed as an outcome, as a predictor of recovery length, and as a correlate of quality of life (QOL) and depression symptomatology Results: Most objective post-concussion sleep quality parameters were adversely affected by concussion but show trajectories indicating improvement throughout the initial 4 weeks of recovery. Sleep quality parameters were not associated with time to complete return to school or activity protocols. Sleep parameters were not strongly correlated with QOL or depression symptomatology outcomes. Conclusions: These results indicate that objective post-concussion sleep quality is impaired following concussion, but these outcomes do not appear to be associated with recovery, QOL or depression symptomatology. Other factors, or improvements in sleep quality may better explain recovery outcomes. / Thesis / Master of Science (MSc) / Children and adolescents are at risk for experiencing changes in sleep following concussion that result in poor sleep quality. Given the important role of sleep in maintaining our overall health, sleep likely plays a role in recovery. However, this relationship is poorly understood. The purpose of this dissertation is to identify how sleep changes following concussion and how these changes affect sleep quality and recovery. Study results reveal that the sleep parameters in the initial 4 weeks following concussion are significantly affected by concussion, suggesting that the sleep quality of children and adolescents is poorer than healthy youth. However, sleep quality does appear to improve with time. Further analyses found sleep quality does not appear to be related to recovery length or outcomes. Thus, the sleep quality of youth may be negatively impacted by concussion, but this may not directly influence recovery.

No / Rhetorically contextualised against a history of poor outcomes and negative attitudes, New Labour’s mental health policy introduced recovery as a turn towards optimism, control and choice for those who provide and use mental health services. Recovery continues to occupy a key role within contemporary policy and practice. Despite such privilege recovery remains a contested concept, not least because it means different things to different people. This article reports empirical work conducted during 2010-11, and explores two interpretive repertoires (traditional and responsibilised-progressive) that mental health practitioners draw upon in their accounts of recovery. Grounded in constructionist theory, the findings suggest that practitioner accounts of recovery are diverse, and produce many different subject positions from which recovery may be experienced. Developing Webber and Joubert’s (2016) editorial comments on the challenge for Social Work, it is argued that professional Social Work must practice in a manner compatible with its own value-base and any model of recovery must be held up for scrutiny. A knowledgeable position for the practitioner is advocated, one that is capable of working multiple paradigms in order to better understand and meet service user need. / ESRC

Pallets represent a large part of the North American solid wood market, with an estimated demand of 1.9 billion pallets in 2024, and 3.1 billion pallets in stock in 2019(Freedonia, 2020). In 2021, 1.18 billion pallets were produced, 919 million were new pallets, and 280 million were repaired or remanufactured (Hobbs, 2024). When pallets reach their end of life, they are landfilled, or recovered by grinding them for mulch or fuel. The objectives of this study are to quantify the number of pallets that are landfilled or recovered, investigate historical trends regarding wood waste at Municipal Solid Waste and Construction and Demolition landfills and investigate alternate uses for pallets. This study was conducted by sending out paper and electronic questionnaires to active landfills in the continental U.S. The study found that 76.8 million pallets, 8.4% of new pallets in 2021, end up in a landfill but 4% of these pallets will be recovered to some useful product such as mulch and only 4.4% will be buried in the landfill. Landfills encourage the population to separate wood before they send material for landfilling, and they are doing this with lower tipping fees. Landfills indicated alternate uses for recovered pallets include alternate daily cover, to ship e-waste, used for road base, given to residents and chipped for mulch or fuel. The study found that 95-97% of wooden pallets produced in the U.S. are repaired for reused, used for repairing other pallets, or converted into value adding by-products. / Master of Science / Pallets are an important part of the supply chain, with 95% of all US packaged products being shipped on pallets. 95% of the demand of pallets are for wooden pallets (Freedonia). This study focuses on investigating the landfilling and recovery of wooden pallets at MSW (general waste) landfills and CandD (construction and demolition waste) landfills. The study was conducted using a survey which was send to both types of landfills. It was found that over 95% of wooden pallets are recovered in some shape or form.

I examined streams in the Joyce Kilmer-Slickrock wilderness to determine if streams responded to logging following 75 y of recovery. Joyce Kilmer was never logged and the Slickrock wilderness was logged from 1917 until 1922. Wood was common in unlogged streams and averaged 417 m³ of wood/ha of streambed. Logged streams had significantly less wood (1.1 m³ of wood/ha of stream), probably because of the construction of railroads in streambeds used to remove timber. Fine substrates (<5.6 mm diameter) were less abundant in logged streams and the retention of fines decreased as wood volume decreased. Species diversity was similar between streams in unlogged and logged catchments; however, the abundance of several taxa and functional feeding groups did differ. Streams in unlogged catchments had significantly greater proportions of shredders while streams in logged catchments had significantly greater proportions of scrapers. Ecosystem parameters showed that the linkages between streams and the forests they drain were weaker in logged than unlogged streams and that unlogged streams derived a greater proportion of fixed carbon from riparian vegetation. Stream-forest linkage strength increased as debris dam abundance increased, while the use of riparian vegetation inputs increased as moss increased. Contrary to predictions, solute storage was significantly greatest in logged catchments and negatively related to debris dam abundance that decreased streambed permeability. Additionally, phosphorus retention, instead of being enhanced by solute storage, was negatively related to transient storage. Uptake velocity was significantly greater in unlogged than logged streams and significantly related to debris dam abundance. Mean breakdown rate of experimental leaf packs and wood veneers was not significantly different between unlogged and logged streams. Leaf breakdown was strongly related to shredder colonization, while wood breakdown was unrelated to variables measured. Much of the persisting disturbance to streams by past logging was directly or indirectly related to differences in wood volume, debris dam frequency, and streambed substrate composition. Results support the hypothesis that logging results in a downstream shift from the headwaters in ecosystem function and that logging disturbance to streams likely persists for centuries. / Ph. D.

The field of mindfulness research is rapidly growing as mindfulness is being utilized as a tool to improve mental and cognitive health. Mindfulness is paying attention in the present moment with non-judgmental awareness. As the research body increases, weaknesses in mindfulness research have surfaced. There is a need for improved measurement tools, an increased understanding of, meditation techniques used, the dose of meditation, and the population samples being studied. Meditation and movement are both tools that can improve an individual's mindfulness. The proposed dissertation will investigate mindfulness through three studies. Study 1 was completed in a population of individual members of the International Quit and Recovery Registry and met the Diagnostic and Statistical Manual, 5th edition criteria for substance use disorder. It was found that individuals with higher mindfulness and engagement with Integrative Health Practices demonstrate success in recovery, measured by the World-Health Organization Quality of Life Scale, craving, and Days in Recovery and are more likely to have reached remission. Engagement with meditation showed more and higher correlations with success in recovery than other Integrative Health Practices measured. Study 2 investigated how mindfulness is taught. Participants were divided into two groups, comparing traditional cueing to compassion cueing. Participants received neuroscience education paired with weekly meditation techniques. There were no group differences; however, all participants expressed improvements in mindfulness, self-compassion, decreased depression symptoms, and gains in neuroscience knowledge. The impact of mindfulness curriculum development can be seen through differences in daily outcomes assessing participants' thoughts, emotions, and body on a 10-point Likert scale from settled to active. Study 3 validated a new tool to measure the multidimensional impacts of movement based on a traditional yogic framework and validated with neuroscience tools. The Multidimensional Impacts of Movement Scale (MIMS) is a valid and reliable tool showing stability over time (r = 0.737, p<0.001) and strong Cronbach's Alpha for each scale ranging from α = 0.775 to α = 0.840. These three studies combine as a body of work supporting continued research in the field of mindfulness by adding new knowledge about teaching mindfulness, measuring mindfulness, and how mindfulness can be applied to improve quality of recovery for individuals with substance use disorder. / Doctor of Philosophy / The field of mindfulness research is rapidly growing as mindfulness is being utilized as a tool to improve mental and cognitive health.

In many physiological studies, variables of interest are not directly accessible, requiring that they be estimated indirectly from noisy measured signals. Here, we introduce two empirical methods to estimate the true physiological signals from indirectly measured, noisy data. The first method is an extension of Tikhonov regularization to large-scale problems, using a sequential update approach. In the second method, we improve the conditioning of the problem by assuming that the input is uniform over a known time interval, and then we use a least-squares method to estimate the input. These methods were validated computationally and experimentally by applying them to flow-through respirometry data. Specifically, we infused CO2 in a flow-through respirometry chamber in a known pattern, and used the methods to recover the known input from the recorded data. The results from these experiments indicate that these methods are capable of sub-second accuracy. We also applied the methods on respiratory data from a grasshopper to investigate the exact timing of abdominal pumping, spiracular opening, and CO2 emission. The methods can be used more generally for input estimation of any linear system. / Master of Science / The goal of an inverse problem is to determine some signal or parameter of interest that is not directly accessible but can be obtained from an observed effect or a processed version that is measurable. Finding the gas exchange signal in animals is an example of an inverse problem. One method to noninvasively measure the gas exchange rate of animals is to put them in a respirometry chamber, flow air through the chamber, and measure the concentration of the respiratory gasses outside the chamber. However, because the gasses mix in the chamber and gradually flow through the gas analyzer, the pattern of the measured gas concentration can be dramatically different than the true pattern of real instantaneous gas exchange of the animal. In this thesis, we present two methods to recover the true signal from the recorded data (i.e., for inverse reconstruction), and we evaluate them computationally and experimentally.
