Natural fire return intervals are relatively long in eastern Canadian boreal forests and often allow for the development of stands with multiple, successive cohorts of trees. Multi-cohort forest management (MCM) provides a strategy to maintain such multi-cohort stands that focuses on three broad phases of increasingly complex, post-fire stand development, termed “cohorts”, and recommends different silvicultural approaches be applied to emulate different cohort types. Previous research on structural cohort typing has relied upon primarily subjective classification methods; in this thesis, I develop more comprehensive and objective methods for three common boreal mixedwood and black spruce forest types in northeastern Ontario. Additionally, I examine relationships between cohort types and stand age, productivity, and disturbance history and the utility of airborne LiDAR to retrieve ground based classifications and to extend structural cohort typing from plot to stand-levels. In both mixedwood and black spruce forest types, stand age and age related deadwood features varied systematically with cohort classes in support of an age-based interpretation of increasing cohort complexity. However, correlations of stand age with cohort classes were surprisingly weak. Differences in site productivity had a significant effect on the accrual of increasingly complex multi-cohort stand structure in both forest types, especially in black spruce stands. The effects of past harvesting in predictive models of class membership were only significant when considered in isolation of age. As an age emulation strategy, the three cohort model appeared to be poorly suited to black spruce forests where the accrual of structural complexity appeared to be more a function of site productivity than age. Airborne LiDAR data appear to be particularly useful in recovering plot-based cohort types and extending them to the stand-level. The main gradients of structural variability detected using LiDAR were similar between boreal mixedwood and black spruce forest types; the best LiDAR-based models of cohort type relied upon combinations of tree size, size heterogeneity, and tree density related variables. The methods described here to measure, classify, and predict cohort-related structural complexity assist in translating the conceptual three cohort model to a more precise, measurement based management system. In addition, the approaches presented here to measure and classify stand structural complexity promise to significantly enhance the detail of structural information in operational forest inventories in support of a wide array of forest management and conservation applications.

Background: Sit-to-stand is a challenging task as it requires the transition from a large 3-point base of support to a small 2-point base of support while simultaneously controlling anteroposterior and vertical body acceleration. Age-related morphological changes in both the visual and vestibular system could impair the ability to extract and interpret sensory information necessary for motor control in older adults, which can increase instability and the risk of falls. The purpose of this study is to understand the effects of aging on visual-vestibular interaction for maintaining stability during sit-to-stand. Methods: Fifteen younger (age=22.5±1.1) and fifteen older (age=73.9±5.3) healthy adults were asked to stand from a sitting position as quickly as possible. Vestibular input was manipulated using percutaneous bipolar galvanic vestibular stimulation where threshold intensity was individually calculated for each participant during quiet stance with eyes closed. Galvanic vestibular stimulation was applied at both threshold (1xGVS) and 2-times the participant’s threshold intensity (2xGVS). Visual conditions included eyes opened, wearing custom-made vision blurring goggles, or eyes closed. Outcome measures included a global measure of performance (transition phase duration), mediolateral stability (peak-to-peak trunk roll angle, mediolateral center of mass displacement, mediolateral center of pressure displacement) and anteroposterior stability (peak braking force, peak-to-peak trunk pitch angle, and peak anteroposterior center of mass velocity). Results: When vision was suboptimal (blurring goggles), older adults had significantly longer transition phase duration than younger adults (p<0.05). Older adults demonstrated greater mediolateral instability than younger adults. When vision was absent, trunk roll angle was significantly greater with 1xGVS than 2xGVS (p<0.05). Mediolateral center of mass displacement was greater when vision was absent than when vision was available, irrespective of age (p<0.05). No effects of age, vision or galvanic vestibular stimulation were seen in peak braking force, trunk pitch angle, and peak anteroposterior center of mass velocity (p>0.05). Conclusion: Regardless of age, visual inputs were more critical to maintain stability during sit-to-stand than vestibular inputs. Differences between younger adults and older adults were only seen in the mediolateral direction. Despite having greater mediolateral instability, older adults utilized similar strategies as younger adults to overcome sensory perturbations during sit-to-stand. / Thesis (Master, Rehabilitation Science) -- Queen's University, 2013-09-20 23:22:16.695

The Master and Kim - Artistic Research Projects that concern questions about musical narration. How can a single person with a flute on an empty scene create a daring and entertaining storytelling? A story that moves freely between realism and stylization.And how can the same person, together with the audience, create a forum where the audience can move between being observers and actors?   In four shows, Kim has explored these issues in various ways. Labored with different scenes, audience placement, balance between oral versus musical narrative.All the performances have both the stories and music written by Kim, and performed together with various fellow musicians. During his education, Kim has had both musical and theatrical supervision.The performances have been documented and evaluated by the audience in place, with distributed papers with the call: "Describe Your Experience". And thus the reflection on the project's issues has been compared with the audience's reception.The result of the project has become a number of methods for designing this highly individual storyteller. Which spans music theater to “recorder-stand up”.

This thesis is a description and analysis of work that I produced during my Gradate studies at the University of New Orleans. The central theme of these works is the common human experience of inner dialogue, an interior experience. Through prints and sculpture I produce stand-ins for the body. These objects are meant to invite the viewer to sense recognizable human traits and to experience the works as having been "lived in."

In this dissertation, it is my intention to show how Stephen King transcends genre, creates and maintains a viable Secondary Reality, and treats capably those literary techniques that critics expect of a serious writer. In addition, I will discuss the ways in which King has secured the loyalty of his Constant Reader. The primary means of my analysis will be through a close reading of the "expanded and uncut" version of The Stand, one of the classics in King's arsenal. I will begin with an overview of the general set-up in the novel---the start in Arnette, Texas, the actions of the military and media, and the 99.4% communicability of the flu itself. From there, I will delve into detailed character analyses of the main players in the story, before moving on to questions of the bigger picture---good vs evil, the question of choice, the Stand itself, the issue of government, and the promise of the future. I will conclude with a brief look at King's style and consider the overall reasons for his popular appeal. It is my hope that such a lengthy look at one of King's novels---instead of the brief chapters devoted to each of his novels in turn---will reveal not only the reasons why King is worthy of serious study, but will show that King's work does stand up to in-depth criticism, thereby answering one of the key questions of current King scholarship: is there enough in King to work with? Everybody agrees that King can crank out lengthy novels without much trouble; it is my intention to peak [sic] into the corners and down into the basement, if for no other reason than to find out if there really is a bogeyman hiding in there, or if it is merely an over-inflated rag doll of fandom. Either way, whether the horror be in the text or in the lack of substance in the text, I hope that my examination will lend new insight to the study of The Stand, and perhaps pave the way for other in-depth studies of other King novels.

During pregnancy the female body must accommodate the enlarging gravid uterus and increased mass. Therefore the maternal musculoskeletal system is required to adapt in both morphology and functional workload. After childbirth there is a rapid change in both mass and dimensions, requiring further adaptations. The objectives of the study were to investigate seated and standing upper body posture, the kinematics of seated and standing trunk motion, and the three dimensional kinematics and kinetics during rising to stand from a chair, as pregnancy progressed and in the early post-birth period. Nine maternal subjects (aged 28 to 40 years) were tested at less than 16 weeks, 24 weeks, 30 weeks, 38 weeks gestation and at 8 weeks postbirth. The subjects, fitted with 37 retroreflective markers, were filmed during upright sitting, quiet standing, and four trials each of maximum seated and standing trunk forward flexion, side to side flexion and during maximum seated axial rotation. Three trials each of constrained and free rising to stand from a height adjustable stool and with each foot placed on a forceplate were also recorded. An eight-camera motion analysis system was used to record movements of the body segments and synchronised force plate variables in three dimensions. Motion of the ankle, knee and hip joints, pelvic, thoracic and head segments and the thoracolumbar and cervicothoracic spines and shoulder joints were investigated. Twelve nulliparous subjects (aged 21 to 35 years) were used as controls to provide standard descriptive data and to investigate the consistency of the selected biomechanical variables with repeated testing. A repeated measures ANOVA was used to investigate the possibility of linear and quadratic trends showing systematic changes within the maternal group, over the four test sessions during pregnancy for each variable. Two tailed Student t-tests were used to compare the maternal postbirth variable results with the control group. There was no significant effect of pregnancy on the upper body posture during upright sitting and quiet standing. Postbirth, the pelvic segment had a smaller anterior orientation and the thoracolumbar spine was less extended, indicating a flatter spinal curve. The maternal subjects were similar to the control subjects in early pregnancy and postbirth for trunk segment motions during seated and standing forward flexion and side to side flexion and seated axial rotation. Strategies, such as increasing the width of the base of support and reducing obstruction to movements from other body parts, were used in late pregnancy in attempts to minimise the effects of increased trunk mass and circumference. For seated and standing side to side flexion, the strategies were successful and no significant decreases in range of motion were seen. For seated and standing forward flexion and seated axial rotation, motion of the thoracic segment and the thoracolumbar spine were significantly reduced, although movement of the pelvis was less affected. In early pregnancy and postbirth the kinematics and kinetics of the lower limbs and upper body segment kinematics during constrained and free rising were generally similar to the control subjects. As pregnancy progressed there were increases in mass and dimensions of body segments. The effect of increased mass was seen in increased ground reaction forces and sagittal plane lower limb joint external moments. An increased base of support width was found in association with an increased lateral ground reaction force and ankle inversion moment from each foot, which would move the body centre of mass medially. There was little change in the three dimensional kinematics of the thoracolumbar and cervicothoracic spine, although the contribution of the upper body segments differed for each rise condition. There were also few significant changes in the displacement of the ankle, knee and hip, and the angular velocity of ankle and knee joints. The maternal subjects were thus able to flex the upper body forward, raise the body and maintain stability as pregnancy progressed, regardless of whether the rise to stand was performed in a natural manner or under constrained conditions. The overall results show that, contrary to expectations as pregnancy progressed, maternal subjects minimised propulsion rather than increasing it to overcome the increased mass and possibly limited trunk flexion. A fear of postural instability may have made the subjects more cautious and as they were able to adequately flex the trunk forward, propulsion was minimised in favour of maintaining upright terminal balance.

<p>This article examines the case of Filipina women that substitute for Filipina migrant workers. Through semi-structured interviews in the Philippines this study draws attention to the experiences of the ‘stand-in’ women and demonstrates how the organisation of care in the transnational families is based on a system whereby female family members or friends are ascribed with a ‘natural’ responsibility to become social reproductive stand-ins for the migrated mothers. In the global transfer of social reproduction, hierarchies of women are maintained, based on intersectional power structures such as ethnicity, race, nationality, age, and class. But the stand-in women in the three-tier transfer of reproductive labour, or global care chain, do not  always occupy one single position, but actually shift in time and place between ‘the middle’ and ‘the bottom’ of the hierarchy. Regardless of location, Filipina women remain under the burden of their gendered duties and whether working abroad as domestic workers or acting as local stand-ins, they have to take on both local and global social reproductive work. They become the breadwinner in their families, at the same time as they are ascribed natural responsibility for households and families, as wives, mothers and stand-ins ‘at home’.</p>
