description: The research described in this thesis focuses on glucose repression of gene expression in a higher eukaryotic organism, the fruit fly Drosophila melanogaster. The results show that DNA sequences which are located upstream of the transcribed region of the amylase gene (Amy) control glucose repression in D. melanogaster larvae. Hybrid constructs, in which the upstream flanking sequences of the amylase gene were fused with the transcribed region of the alcohol dehydrogenase gene (Adh), were expressed in transgenic $Adh\sp{\rm null}$ larvae. The expression of ADH from the hybrid gene was found to be subject to glucose repression. The function of potential regulatory cis-acting elements within the glucose responsive upstream region of the amylase gene was examined by deletion analysis and site-directed mutagenesis, coupled with expression assays in somatically transformed $Amy\sp{\rm null}$ larvae. The upstream deletion analysis showed that essential elements, both for overall activity and glucose repression of the amylase gene, are located close to the transcription start site (within 109 base pairs). In vitro site-directed mutagenesis of upstream sequences revealed that the TATA motif, at position $-$28, and a novel 35 base pair element, at position $-$109 to $-$74 with respect to the transcription start site, were necessary for overall activity of the amylase promoter. None of the introduced mutations, which scanned the upstream regulatory region of the amylase gene, resulted in the loss of glucose responsiveness. These results suggest that glucose repression, in Drosophila, is mediated by transcriptional mechanisms which involve multiple functionally redundant DNA elements. Variation in the degree of glucose repression of the amylase genes was examined at a molecular level in D. melanogaster. Gene-specific elements located within a short upstream DNA region were shown to regulate the difference in response to dietary glucose between duplicated amylase genes. In addition, in order to assess the effect of interspecific variation of regulatory DNA sequences on glucose repression, the function of glucose repressible amylase promoters was examined in distantly related species. The D. virilis amylase gene was shown to be repressed by dietary glucose in somatically transformed D. melanogaster larvae. (Abstract shortened by UMI.)

description: Millisecond pulsars are thought to be neutron stars that have been spun-up by accretion of matter from a binary companion. Although most are in binary systems, some 30% are solitary, and their origin is therefore mysterious. PSR J1719-1438, a 5.7 ms pulsar, was detected in a recent survey with the Parkes 64 m radio telescope. We show that it is in a binary system with an orbital period of 2.2 h. Its companion's mass is near that of Jupiter, but its minimum density of 23 g cm−3 suggests that it may be an ultra-low-mass carbon white dwarf. This system may thus have once been an Ultra Compact Low-Mass X-ray Binary, where the companion narrowly avoided complete destruction.

description: Background Hereditary Angioedema (HAE), a rare genetic disease, manifests as intermittent, painful attacks of angioedema. Attacks vary in frequency and severity and include skin, abdominal and life-threatening laryngeal swellings. This study aimed to develop a patient reported outcome (PRO) tool for the assessment of HAE attacks, including their management and impact on patients’ lives, for use in clinical studies, or by physicians in general practice. Methods The results of open-ended face to face concept elicitation interviews with HAE patients in Argentina (n = 10) and the US (n = 33) were used to develop the first draft questionnaire of the HAE patient reported outcomes questionnaire (HAE PRO). Subsequently, in-depth cognitive debriefing interviews were performed with HAE patients in the UK (n = 10), Brazil (n = 10), Germany (n = 11) and France (n = 12). Following input from eight multinational clinical experts further cognitive interviews were conducted in the US (n = 12) and Germany (n = 12). Patients who experienced abdominal, cutaneous or laryngeal attacks of varying severity levels were included in all rounds of interviews. Across the rounds of interviews patients discussed their HAE attack symptoms, impacts and treatments. Cognitive debriefing interviews explored patient understanding and relevance of questionnaire items. All interviews were conducted face to face following a pre-defined semi-structured interview guide in the patient’s native language. Results Patients reported a variety of HAE symptoms, attack triggers, warning signs, attack impacts and treatment options which were used to develop the HAE PRO. The HAE PRO was revised and refined following input from patients and clinical experts. The final 18-item HAE PRO provides an assessment of the HAE attack experience including symptoms, impacts, treatment requirements, healthcare resource use and loss of productivity caused by HAE attacks. Conclusions Patient and expert input has contributed to the development of a content valid questionnaire that assesses concepts important to HAE patients globally. HAE patients across cultures consider the HAE PRO a relevant and appropriate assessment of HAE attacks and treatment.

description: Instructional coaches support teachers in referring and evaluating students through the learning disability (LD) identification process in Saudi Arabia. The instructional coaches also help students as they do day-to-day learning and assessment tasks. This study explored instructional coaches’ perspectives about the current model for identifying students with LD, its effectiveness, and the potential implementation of Multi-Tiered Systems of Support (MTSS) as an alternative model. This study used semi-structured interviews with 12 instructional coaches to evaluate Saudi Arabia’s current identification methods. The results highlighted significant concerns about accuracy of identification and the risks of misidentifying students with LD. The findings suggest that MTSS, although it is not currently employed in Saudi schools, could provide a more reliable and comprehensive approach to addressing students’ academic and behavioral needs. Emphasizing the need for culturally- and linguistically-appropriate Special Education practices, the study advocates for MTSS’s gradual implementation with teacher training. This study contributes to the understanding about LD identification in Saudi schools and positions MTSS as an alternative solution for more effective support and identification. This study includes practical implications and recommendations for future research.

description: Background: The depth of chest compression (CC) during cardiac arrest is associated with patient survival and good neurological outcomes. Previous studies showed that mattress compression can alter the amount of CCs given with adequate depth. We aim to quantify the amount of mattress compressibility on two types of ICU mattresses and explore the effect of memory foam mattress use and a backboard on mattress compression depth and effect of feedback source on effective compression depth. Methods: The study utilizes a cross-sectional self-control study design. Participants working in the pediatric intensive care unit (PICU) performed 1 min of CC on a manikin in each of the following four conditions: (i) typical ICU mattress; (ii) typical ICU mattress with a CPR backboard; (iii) memory foam ICU mattress; and (iv) memory foam ICU mattress with a CPR backboard, using two different sources of real-time feedback: (a) external accelerometer sensor device measuring total compression depth and (b) internal light sensor measuring effective compression depth only. CPR quality was concurrently measured by these two devices. The differences of the two measures (mattress compression depth) were summarized and compared using multilevel linear regression models. Effective compression depths with different sources of feedback were compared with a multilevel linear regression model. Results: The mean mattress compression depth varied from 24.6 to 47.7 mm, with percentage of depletion from 31.2 to 47.5%. Both use of memory foam mattress (mean difference, MD 11.7 mm, 95%CI 4.8–18.5 mm) and use of backboard (MD 11.6 mm, 95% CI 9.0–14.3 mm) significantly minimized the mattress compressibility. Use of internal light sensor as source of feedback improved effective CC depth by 7–14 mm, compared with external accelerometer sensor. Conclusion: Use of a memory foam mattress and CPR backboard minimizes mattress compressibility, but depletion of compression depth is still substantial. A feedback device measuring sternum-to-spine displacement can significantly improve effective compression depth on a mattress. Trial registration Not applicable. This is a mannequin-based simulation research.

Novel geometric metric for uncertainty accumulation in life cycle assessment
Creators: name: Raman, Arvind Shankar
Publisher: name: Washington State University
Year: 2013
Subjects: Life cycle costing--Environmental aspects--Mathematical models

description: Life-Cycle Assessment (LCA) is a technique used to estimate the environmental impact of any product from its inception to disposal. Quantification of environmental impact is accompanied by a certain level of uncertainty with it; the objective of this research is to create a geometric metrics of uncertainty on parameters that contribute to environmental impact. In mechanical design, LCA is performed at end of design stage, implying that the product is not yet manufactured, used or disposed off. Therefore, data utilized in LCA is estimated from similar products all across the board. Data utilized in such LCA study is from different processes, products, technologies, different geographic locations, areas of application and time frame. Therefore, there is large uncertainty in data utilized in LCA. There are multiple factors that contribute to uncertainty in LCA. The four environmental impacts included in this study are Air Acidification, Water Eutrophication, Carbon emission and Energy. Individual uncertainties of these parameters play a huge role on consolidated uncertainty in LCA. Consolidation of these individual uncertainties can be linear or non-linear based on multiple factors and parameters. This research focuses on creating a metrics for these linear or non-linear effects on uncertainty between the parameters that contribute to environmental impact. A visual representation of impacts of these four parameters on uncertainty will provide a much better understanding on the design flaws and its improvement. This research is creating a Novel geometric metric for the uncertainty in the process parameters is developed using Barycentric co-ordinates and mapped onto a hypothetical space called S-Map (Sustainability Map). S-Map, a bounded space for multiple process parameters can be accumulated using a mathematical technique called, convolution for multiple convex multi-dimensional shapes. The accumulated S-map is the total uncertainty of all environmental impacts of a product life-cycle. This research focuses on creating an effective algorithm for non-convex to non-convex or non-convex to convex accumulation of multi-dimensional shapes for uncertainty accumulation in LCA. The research also calculates the effect of statistical distribution on each parameter, which governs the uncertainty quantification. Resulting S-map created using this research is a geometric metric of uncertainty accumulation.

description: The purpose of this dissertation is to advance economic applications pertaining to agriculture, specifically in labor and crop insurance. The first chapter summarizes relevant background, research objectives, and key findings of the dissertation chapters. The second chapter considers the impacts of the COVID-19 pandemic on labor market outcomes in essential sectors of the U.S. labor market. Our findings highlight the ambiguous nature of the reservation wage and job characteristic changes in the first three months of the pandemic. We find evidence of unbalanced responses by individual gender, race-ethnicity, immigrant status, education, and household income. Findings also vary with respect to the sector and subsector analyzed. The third chapter highlights the effect of the crop insurance revenue protection basis adjustment to projected prices for winter wheat farmers in Washington. We utilize a representative farmer from Whitman County, Washington to model utility generated from producing soft white or hard red winter wheat. While the policy establishing the basis adjustment does not distinguish between classes of production, there exists evidence that the benefit of enrollment is not equal for both classes. The
description: fourth chapter applies a simultaneous system framework to consider the farmer decision to allocate cropland acreage to winter wheat and participate in crop insurance. We consider three state samples at the county-level, as well as an combined sample used to represent total U.S. winter wheat production. We find evidence of heterogeneous response to factors contributing to acreage allocation and insurance participation. We find region-specific response to the modernization of crop insurance, but we do not find evidence of the basis adjustment impacting acreage allocation or insurance participation.

description: In many Sub-Saharan African settings male partner involvement in antenatal care (ANC) remains low, although great benefits for maternal and infant health outcomes have been long recognised, in particular regarding the prevention of HIV transmission. Yet there is paucity on evidence regarding the effectiveness of strategies to increase male partner involvement. This controlled intervention trial in Ruanda Health Centre in Mbeya, Tanzania, assessed the effectiveness of invitation letters for male involvement in ANC. Pregnant women approaching ANC without partners received official letters inviting the partner to attend ANC. A control group was instructed to verbally invite partners. Partner attendance was recorded at two subsequent ANC visits. Rates for male partner return, couple voluntary counselling and testing (CVCT), and influencing factors were analysed. From 199 ANC clients in total, 97 were assigned to the invitation letter group; 30 of these (30.9%) returned with their male partners for ANC. In the control group of 102 women, 28 (27.5%) returned with their partner. In both groups CVCT rates among jointly returning couples were 100%. Partner return/CVCT rate was not statistically different in intervention and control group (OR 1.2, p = 0.59). Former partner attendance at ANC during a previous pregnancy was the only factor found to be significantly linked with partner return (p = 0.03). Our study demonstrates that rather simple measures to increase male partner attendance in ANC and CVCT can be effective, with written and verbal invitations having comparable outcomes. In terms of practicability in Sub-Saharan African settings, we recommend systematic coaching of ANC clients on how to verbally invite male partners in the first instance, followed by written invitation letters for partners in case of their non-attendance. Further studies covering both urban and rural settings will be more informative for effective translation into policy.

A critical interpretation of Kierkegaard's "Philosophiske Smuler".
Creators: name: Lande, Vidar.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1990
Subjects: subject: Philosophy.

description: As the title says, the thesis is "a critical interpretation of Kierkegaard's Philosophiske Smuler" (Philosophical Fragments). The thesis intends thus to read this work "critically". It goes through the text chapter by chapter, but does not limit its analyses to direct reading of the texts. The reading is "intentional" in the sense that it attempts also to take into account the states of mind which must have produced the text. In this way the method is "phenomenological". It attempts ultimately to approach the "phenomena" behind the texts, i.e. the experiences corresponding to the textual manifestations. Given this phenomenological intention, it appears that Kierkegaard's pseudonymous author of Philosophiske Smuler, Johannes Climacus, shares spiritual experiences with religious mystics. The thesis attempts to express these experiences in a language which can suit comparative purposes with Climacus. In order to show how mysticism enters Climacus' mind, one could refer to examples on almost every page throughout Philosophiske Smuler. If we approach mysticism from a purely psychological perspective, we will also find a clear correspondence between Climacus' description and what psychologists of religion say about the highest mystic states of consciousness. The well-known psychologist in the Freudian tradition, James Henry Leuba, calls the ultimate experience of mystics a "sweet bliss", in which "sex organs participate, tormented by an insufficient stimulation". Chapter 1 of the thesis contains a detailed explanation of mystic concepts. But in order to avoid any misunderstandings on this important issue, the reader should consult the glossary in the end of the thesis. This glossary explains the most important mystic concepts and gives references to the pages in the thesis where they occur. The glossary also points out the most important places in Kierkegaard's text of Philosophiske Smuler where the mystic concepts are most relevant. (Abstract shortened by UMI.)

description: We present the discovery of six millisecond pulsars (MSPs) in the High Time Resolution Universe (HTRU) survey for pulsars and fast transients carried out with the Parkes radio telescope. All six are in binary systems with approximately circular orbits and are likely to have white dwarf companions. PSR J1017-7156 has a high flux density and a narrow pulse width, making it ideal for precision timing experiments. PSR J1446-4701 and PSR J1125-5825 are coincident with gamma-ray sources, and folding the high-energy photons with the radio timing ephemeris shows evidence of pulsed gamma-ray emission. PSR J1502-6752 has a spin period of 26.7ms, and its low period derivative implies that it is a recycled pulsar. The orbital parameters indicate it has a very low mass function, and therefore a companion mass much lower than usually expected for such a mildly recycled pulsar. In addition we present polarization profiles for all 12 MSPs discovered in the HTRU survey to date. Similar to previous observations of MSPs, we find that many have large widths and a wide range of linear and circular polarization fractions. Their polarization profiles can be highly complex, and although the observed position angles often do not obey the rotating vector model, we present several examples of those that do. We speculate that the emission heights of MSPs are a substantial fraction of the light cylinder radius in order to explain broad emission profiles, which then naturally leads to a large number of cases where emission from both poles is observed.

description: Bilge water accumulates in recesses and bilges onboard ships. Depending on the type of design and age, ships can generate large volumes of bilge water. This wastewater is a mixture of fresh water and seawater containing various contaminants. Typical contaminants may include fuels, oils, greases, detergents, solvents, rusts, paints, insulation material and a wide variety of other substances. Bilge water is a very challenging wastewater to treat due to large variations in production rates and the complex nature of the wastes in solution. Membrane based Oily Water Separators (OWS) are being increasingly used throughout the world for the treatment of oily wastewater. This work focused on two areas of study: (1) Effects of selected components found in bilge water on membrane performance, and (2) Pilot scale testing using a Microfiltration/Ultrafiltration (MF/UF) hybrid system. The studies are aimed at determining suitable membrane materials and optimum operating conditions such as trans-membrane pressure (TMP) and backflushing for permeate flux enhancement.

description: Background Retention to HIV care is vital for patients’ survival, to prevent onward transmission and emergence of drug resistance. Travelling to receive care might influence adherence. Data on the functioning of and retention to HIV care in the Central African region are limited. Methods This retrospective study reports outcomes and factors associated with retention to HIV care at a primary HIV clinic in Lambaréné, Gabon. Adult patients who presented to this clinic between January 2010 and January 2012 were included. Outcomes were retention in care (defined as documented show-up for clinical visits, regardless of delay) or LTFU (defined as a patient not retained in care; on ART or ART naïve, not returning to care during the study period with a patient delay for scheduled visits of more than 6 months), and mortality. Cox regression analysis was used to assess factors associated with respective outcomes. Qualitative data on reasons for LTFU were obtained from focus-group discussions. Results Of 223 patients included, 67.3% were female. The mean age was 40.5 (standard deviation 11.4) years and the median CD4 count 275 (interquartile range 100.5–449.5) cells/μL. In total, 34.1% were lost to follow up and 8.1% died. Documented tuberculosis was associated with increased risk of being LTFU (adjusted hazard ratio (aHR) 1.80, 95% confidence interval (95% CI) 1.05–3.11, P = 0.03), whereas early starting anti-retroviral therapy (ART) was associated with a decreased risk of LTFU (aHR 0.43, 95%CI 0.24–0.76, P = 0.004), as was confirmed by qualitative data. Conclusions Retention to HIV care in a primary clinic in Gabon is relatively poor and interventions to address this should be prioritized in the HIV program. Early initiation of ART might improve retention in care.
A purposeful rebuilding: YouTube, representation, accessibility and the socio-political space of disability
Creators: name: Ellis, Katie
Publisher: name: Swinburne
Year: 2024

description: YouTube, which has provided opportunities to some people with disabilities while excluding others, highlights the importance of a cultural conversation about the future of telecommunications in relation to both content and the medium of transmission. As disability cultural movement emerged in the 1990s, activists, academics and media producers argued that people with disability should be in charge of their own image. The representation of disability in the media and how disability theorists have suggested this should change in order to improve the social position of people with disability. It allows for different types of representations and encourages discussions. YouTube's recent focus on accessibility reveals that impairment and disability are crucial factors influencing whether people with disability can access this technology.

description: The techniques of electrophoresis have undergone rapid development in recent years. The problem of predicting and explaining results of electrophoretic experiments requires a well designed dynamical model that reproduces the proper dynamics under well-understood conditions. The challenge is to design a model which can predict complex dynamics in a variety of situations of interest and yet, be efficient enough to run on common workstations. We believe that we have been successful in achieving these goals. Our Brownian Dynamics model is sufficiently general for the investigation of a wide variety of problems (as we will demonstrate), moreover, it implements a simulation innovation, a dynamically self-regulating time increment which varies in accordance with the stresses in the system. This permits for reasonably long simulation times with good averaging statistics. After benchmarking the model with the well understood Rouse regime in isotropic and confined media, the model was applied to two case studies of particular interest: (i) electrophoretic collisions and stacking (chain pinning), and (ii), the onset of the entropic trapping regimes for low fields. We have found that, as far as simple isolated collisions are concerned, our model predicts a widening of electrophoretic molecular bands with an accompanying loss in spatial resolution. The onset of entropic regimes for low fields is demonstratedly counter-productive due to the wide variance of trapping times. Both these results are in accord with recent experimental observations. A more complete study is planned for a supercomputer to elaborate on these findings as well as to investigate kink-formations in pulsed-field gel electrophoresis (PFGE).

Acupuncture comes to Canada: The struggle for professional recognition, 1970-1996.
Creators: name: Yuan, Wei.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2001
Subjects: subject: History of Science.

description: Drawing material from news media, organizational archives, medical journals, governmental and legislative documents as well as oral history interviews, this study examines the introduction and development of acupuncture in Canada covering the period from 1970 to 1996. It is a social professional and legislative history with an analytical narrative approach. The knowledge transfer of acupuncture from China to Canada and its cultural adaptation were part of the ongoing holistic health movement and results of new public policies in diplomacy, immigration, culture and health care. Medicalization of acupuncture was the response of the Canadian medical profession to gain control of the practice of acupuncture. Its tactics included: claiming acupuncture as a medical act, simplifying acupuncture to a technique, and subordinating and excluding traditional acupuncturists. In practice, brief training sessions were provided to a large number of physiotherapists and physicians. The study also notes the changing attitude of orthodox medicine toward acupuncture. The thesis focuses on the intricate relations of the acupuncturists, the medical establishment, the government, the judicial system and the public. The conflicts and frictions among these parties are illustrated. Rival acupuncture groups were created in Quebec in the 1970s and a united front was formed at the end of 1980s. The Acupuncture Association of BC had directed the acupuncture movement in that province since 1974. Organizational activities started in Alberta and Ontario in the early 1980s. The acupuncturists' strategies for professionalization are described and analyzed. Acupuncturists had struggled in a very challenging environment created by the medical establishment and the existing legislative framework. Throughout the 1970s and 80s, acupuncturists were prosecuted in Quebec and BC. The courts in Alberta (1979) and Ontario (1980), however, interpreted the law in favor of non-medical acupuncture. The connection of new health policies to the emergence of acupuncture as a professionalized health care system is depicted and explained. By the mid-1990s, traditional acupuncture had obtained public recognition and political endorsement in BC, Alberta and Quebec with Ontario following suit. In short, this thesis shows how the acupuncturists' struggle plus the changing societal attitudes brought about the legitimacy of acupuncture in Canada at the end of the 20th century.
title: AI for teams: The future of assisted collaborative work

description: My ethnographic fieldwork is focused on the role of artificial intelligence in the workplace, building on well-established themes in CSCW and also identifying new challenges in observations of distributed agencies and skill in collaborative work. Grounded in an increased and varied academic interest in the environments, policies and rights related to the future of work and a strong industry narrative around ways of work made possible by technology, I am interested in the deep change aspirations of artificial intelligence and machine learning applications and their role in a push for “digital transformation.” I seek to complement extensive but seemingly narrow studies of e.g. bias, trust and explanation in specific implementations where these fail to capture concerns we should have for work. Broadly, I want to ask, What is it that we’re trying to digitally transform with artificial intelligence? What happens in that transformation? How can we zoom out and expand our frame of reference?

Private Forest Governance, Public Policy Impacts: The Forest Stewardship Council in Russia and Brazil
Creators: name: Sundstrom, Lisa McIntosh

Publisher: name: Multidisciplinary Digital Publishing Institute
Year: 2019

description: Under what conditions do private forest governance standards influence state policy and behavior to become more oriented toward sustainability? We argue that governance schemes targeting firms may indirectly shape state behavior, even when designed to bypass state regulation. Through an examination of the Forest Stewardship Council (FSC) in Russia and Brazil, we find that the FSC has influenced domestic rhetoric, laws, and enforcement practices. FSC has had a more disruptive and consequential impact on Russia’s domestic forest governance; in Brazil, earlier transnational environmental campaigns had already begun to shift domestic institutions toward sustainability. Based on interview data and textual analysis of FSC and government documents, we identify the mechanisms of indirect FSC influence on states—professionalization, civil society mobilization, firm lobbying, and international market pressure, and argue that they are likely to be activated under conditions of poor and decentralized governance, overlapping and competing regulations and high foreign market demand for exports.

Subjects: subject: Engineering, Electronics and Electrical.

description: In optical communication systems, messages must be delivered fast and efficiently in order to achieve high quality of service and fully exploit the resources. Two elementary issues that affect this objective are the network topology and the need for fast switching node. The network topology affects the routing and the device cost, while switches affect the exchange of messages from one link to another. Today, these two areas have attracted substantial amount of research interest. In this thesis, a multilayer optical network topology based on the Kautz graph is analyzed first. This multilayer Kautz graph has been proven very useful in the optical network in comparison with some known architectures. This topology has also been implemented with optical passive star couplers and optical switches. Three contention resolution schemes have been examined. Next this multilayer idea is used in the design of a multistage optical switch. This switch architecture has inherited some properties of the known topologies. With a low device cost, it can provide a remarkable advantage in optical packet switching. Finally, we have also discussed some critical issues in the design and implementation of the proposed architectures with available technologies and components.
