description: Gravitational coupling between a gaseous disk and an orbiting perturber leads to angular momentum exchange between them which can result in gap opening by planets in protoplanetary disks and clearing of gas by binary supermassive black holes (SMBHs) embedded in accretion disks. Understanding the co-evolution of the disk and the orbit of the perturber in these circumstances requires knowledge of the spatial distribution of the torque exerted by the latter on a highly nonuniform disk. Here we explore disk-satellite interaction in disks with gaps in linear approximation both in Fourier and in physical space, explicitly incorporating the disk non-uniformity in the fluid equations. Density gradients strongly displace the positions of Lindblad resonances in the disk (which often occur at multiple locations), and the waveforms of modes excited close to the gap edge get modified compared to the uniform disk case. The spatial distribution of the excitation torque density is found to be quite different from the existing prescriptions: most of the torque is exerted in a rather narrow region near the gap edge where Lindblad resonances accumulate, followed by an exponential fall-off with the distance from the perturber. Despite these differences, for a given gap profile the full integrated torque exerted on the disk agrees with the conventional uniform disk theory prediction at the level of ~10%. The nonlinearity of the density wave excited by the perturber is shown to decrease as the wave travels out of the gap, slowing down its nonlinear evolution and damping. Our results suggest that gap opening in protoplanetary disks and gas clearing around SMBH binaries can be more efficient than the existing theories predict. They pave the way for self-consistent calculations of the gap structure and the orbital evolution of the perturber using accurate prescription for the torque density behavior.

When traumatized children come to school: towards understanding teachers' lived experiences of working with students who suffer catastrophic or traumatic events
Creators: name: Sherley, Diane Elaine
Publisher: name: University of Calgary
Year: 2012

description: Bibliography: p. 215-231
description: Classroom teachers work on an ongoing and daily basis with students who suffer traumatic events. As the student suffers, so does the teacher, albeit in different ways. Events may occur suddenly and unexpectedly, such as a shooting, terrorist attack, natural disaster, family member's accident, or a suicide. A student's experience of trauma may also present in the form of an ongoing process such as a medical disease, illness or abuse. For the teacher, this experience is typically unexpected, it usually happens with no specialized preparation, and it plays out in the context of a physical environment that simultaneously includes twenty to thirty other students. It is quite unlike the experience of a therapist, counselor, nurse or doctor who has individualized and uninterrupted extensive blocks of time with a traumatized child, has specialized expertise in the specific trauma area, is fully expecting and is prepared to address emotional needs of the child, and understands self-care issues that support personal coping. The most direct impact for a teacher occurs through relationship in the context of teaching and learning, where pedagogical responses, decisions and acts are continuously lived. This hermeneutic study explores complexities and tensions inherent in this lived teacher experience. Probing occurs through conversations with eight teachers about their experience with a traumatized student, as well as an experience of my own. A specific focus is on what is opened up through a teacher's suffering, and impact and implications for teaching practice. Touchstone theorists that guide the epistemological orientation of this study are Hans-Georg Gadamer in terms of a search for understanding, and Paul Ricoeur in terms of understanding the notion of story. The interpretive nature of this study permeates throughout the dissertation, with elements of teachers' stories presented in Chapters Three, Five and Six. This work hopes to open up and heighten an awareness of the complexities and significance of this experience. It is also hoped that others will be enticed to move into further exploration in continuing, ongoing, and generative ways.

description: We present a web interface for the BioFET-SIM program. The web interface allows to conveniently setup calculations based on the BioFET-SIM multiple charges model. As an illustration, two case studies are presented. In the first case, a generic peptide with opposite charges on both ends is inverted in orientation on a semiconducting nanowire surface leading to a corresponding change in sign of the computed sensitivity of the device. In the second case, the binding of an antibody/antigen complex on the nanowire surface is studied in terms of orientation and analyte/nanowire surface distance. We demonstrate how the BioFET-SIM web interface can aid in the understanding of experimental data and postulate alternative ways of antibody/antigen orientation on the nanowire surface.
Physical and computational models of free surface related defects in low-pressure die-cast aluminum alloy wheels
Creators: name: Duan, Jianglan
Publisher: name: University of British Columbia
Year: 2011

description: The difference of die filling, which can be characterized by the free surface flow behavior, has a strong influence on the quality of casting components. In the case of cast aluminum alloy wheels, an undesired filling pattern with excessive turbulence can cause portions of the surface oxide film to be entrained within the bulk liquid resulting in defects such as cosmetic paint-pops, hot tears, porosity and rim-leaks. To investigate the influence of die filling on defect formation in low-pressure die-cast aluminum wheels, a water analogue physical model was built, instrumented and tested to simulate the free surface behavior during die filling of a low-pressure die-cast (LPDC) wheel. The physical model contains a transparent planar die section which was manufactured out of the geometry of a production die, and an automatic pressure control system that achieves liquid feeding conditions similar to the industrial process. A set of die filling tests with different venting conditions was carried out to explore the role of venting on the free surface behavior of water and to produce data for validation of a computational model. The computational model was developed, based on the commercial computational fluid dynamics code ANSYS CFX, for the purposes of predicting the flow conditions during die filling, providing qualitative and quantitative flow information that are otherwise not possible to obtain through experimental measurement, and identifying key features that influences the flow during die filling at a lower cost of time and labor. Comparison between the experimental and numerical data has shown that the computational model was able to qualitatively reproduce the flow behavior observed in the water model in the conditions tested. Both the experimental and the model results indicate that the entrainment of surface oxide films and air bubbles could occur at the outboard rim flange during the filling of the flange, below the free surface of the returning waves in the spoke and at the junction of the hub and the spoke during the filling of the hub. Venting conditions have been proved crucial and the importance of vent design in commercial die design was highlighted.

description: The purpose of this dissertation is to explore the relationships among understanding, creating and teaching mathematics. It includes two pairs of complementary mathe­matics and education papers. The papers are complementary in the sense that the education papers draw on the experiences of creating the mathematics that appear in the mathematics papers and in doing so, provide insight into how the mathe­matical concepts, theorems and proofs are constructed. The education papers not , only provide insight into one mathematician's creating of mathematics, but mine the experiences and insights for their pedagogical implications.

description: A black universe is a nonsingular black hole where, beyond the horizon, there is an expanding, asymptotically isotropic universe. Such models have been previously found as solutions of general relativity with a phantom scalar field as a source of gravity and, without phantoms, in a brane world of RS2 type. Here we construct examples of static, spherically symmetric black-universe solutions in general relativity with a minimally coupled scalar field ϕwhose kinetic energy is negative in a restricted strong-field region of space-time and positive outside it. Thus in such configurations a "ghost" is trapped in a small part of space, which may in principle explain why no ghosts are observed under usual conditions.

description: Our Land Ethic and our conservation and hunting traditions cannot defend or advance themselves. Such achievements require rhetorical skill, wisdom, confidence, moral clarity and hard work. Skillful persuasion that appeals to ethics and character can most effectively sustain and strengthen our conservations and hunting traditions. Rhetorical skills can be used to re-frame and refute the moral and factual foundations of uninformed or bad-faith arguments that attack hunting and conservation models. It is effective to craft the most effective arguments that justify hunting and conservation as virtuous qualities of the American character and which are necessary for wildlife's survival. Three levels of ethical obligations link us to future generations: duties to the animals and the land; duties to self and duties to society. We cannot preserve for the future if we fail to preserve what we have today. Relationships need to be established among information, wisdom, character, consequences, and persuasion; and how each affects the future of hunting and conservation in our current and evolving culture. We cannot win elections, we cannot win funding, and we cannot win the popular culture unless we first persuasively win the arguments based on ethics and facts. Learn how to win arguments to secure the future of hunting and the land ethic we value.
As a result of the fall: explorations of the trauma postmodern
Creators: name: Kinney, Ian Glen
Publisher: name: University of Calgary
Year: 2012

description: Bibliography: p. 29-31
description: Not only does the traumatic event instigate the subject's confrontation with death, but it can also suggest a narrative subject that is multiple and protean. Through a process of narrative (re)construction, writing about a traumatic event that relates to death (re)actively (re)orients the individual subject to the social world and enables healing. But rather than reconstitute the subject within socially derived narratives and reinforce the logocentric project to signify trauma coherently, a posttraumatic writing may better account for the figural happening of the traumatic event. Posttraumatic writing consents to the indeterminate and comes to terms with that which is unrepresentable to memory and yet which cannot be forgotten. The terms poststructuralism and postmodernism are themselves troubled and troubling figures in a trauma meta-narrative wherein the individual agent no longer operates as the privileged, autonomous subject of modernity, but instead develops fragmented and multiple. By continually (re)arranging 'partial' or 'distorted' phrases and their linkages, my posttraumatic text, entitled "As a Result of the Fall," internalizes the disruption that is poststructuralism, and explores the possibilities of postmodern ism as a liberating, and perhaps even therapeutic aesthetic practice.
The Birth of a Noble Tea Country: on The Geography of Colonial Capital and The Origins of Indian Tea

Publisher: name: Columbia University
Year: 2010

description: This paper looks at the origins of the British tea industry of India from the standpoint of colonial and semicolonial involvement in, respectively, British India and Qing China. The imposition of the tea industry in Assam was integrally tied to the wars in East Asia fought in order to open markets for the movement of opium and other commodities. British officials championed both policies in the name of modern economic progress, liberalizing trade with the Qing and establishing a productive industry in Assam. The agricultural science of political economy aimed to extract the value of various objects which could then be united in a land hitherto considered a wasteland. Plants, soil and labor were each viewed as isolatable things whose values were objective and calculable. Such static representation, however, was already belied by the dynamic process of gathering and transporting these “things” across the vast and unevenly developed regions of Asia, ultimately valorizing them as a breakfast drink commodity enjoyed worldwide. The origins of the Assam tea plantations, mirroring developments elsewhere, relied upon spatio-economic connections that force us to reevaluate how the specific histories of British India, Qing China and Southeast Asia are inseparably linked.
Religious pluralism in theological education

description: In this essay, I will try to explain and ground a conviction that I share with many colleagues in the Christian theological community: that one of the reasons why Christian theological education is not adequately doing its job of mediating between culture and religion has to do with the mono-religions character of most Christian theology today. Theological educators are going about their job on the basis of an exclusive, or too restrictive, use of Christian tradition and experience. They have closed themselves to, or are not sufficiently open to, other religious traditions and identities.

Diversification, Diseconomies of Scope, and Vertical Contracting: Evidence from the Taxicab Industry

description: This paper studies how firms reorganize following diversification, proposing that firms use outsourcing, or vertical disintegration, to manage diseconomies of scope. We also consider the origins of scope diseconomies, showing how different underlying mechanisms generate contrasting predictions about the link between within-firm task heterogeneity and the incentive to outsource following diversification. We test these propositions using microdata on taxicab and limousine fleets from the Economic Census. The results show that taxicab firms outsource, by shifting the composition of their fleets toward owner-operator drivers, when they diversify into the limousine business. The magnitude of the shift toward driver ownership is larger in less urban markets, where the tasks performed by taxicab and limousine drivers are more similar. These findings suggest that (1) firms use outsourcing to manage diseconomies of scope at a particular point in the value chain and (2) interagent conflicts can be an important source of scope diseconomies.

description: The AIDS crisis, the increase in other sexually transmitted diseases (STDs), and the continuing problem of unwanted pregnancies, necessitate new methods of barrier protection. In 1988, Wisconsin Pharmacal began testing the safety and efficacy of a new female condom (Reality), a disposable, prelubricated, polyurethane device that is both a contraceptive and a barrier against STDs. The product requires no professional fitting and is inserted by the woman. Preliminary data from clinical and laboratory studies indicate that the female condom may be an effective barrier against STDs. A widespread use of the female condom, however, will depend on women's and men's initial attitudes, including culturally determined barriers to acceptance.

description: Tsinghua-NAOC (National Astronomical Observatories of China) Telescope (hereafter, TNT) is an 80-cm Cassegrain reflecting telescope located at Xinglong bservatory of NAOC, with main scientific goals of monitoring various transients in the universe such as supernovae, gamma-ray bursts, novae, variable stars, and active galactic nuclei. We present in this paper a systematic test and analysis of the photometric performance of this telescope. Based on the calibration observations on twelve photometric nights, spanning the period from year 2004 to year 2012, we derived an accurate transformation relationship between the instrumental $ubvri$ magnitudes and standard Johnson $UBV$ and Cousins $RI$ magnitudes. In particular, the color terms and the extinction coefficients of different passbands are well determined. With these data, we also obtained the limiting magnitudes and the photometric precision of TNT. It is worthwhile to point out that the sky background at Xinglong Observatory may become gradually worse over the period from year 2005 to year 2012 (e.g., $\sim$21.4 mag vs. $\sim$20.1 mag in the V band).

A two-dimensional one component plasma and a test charge : polarization effects and effective potential

description: We study the effective interactions between a test charge Q and a one-component plasma, i.e. a complex made up of mobile point particles with charge q, and a uniform oppositely charged background. The background has the form of a flat disk, in which the mobile charges can move. The test particle is approached perpendicularly to the disk, along its axis of symmetry. All particles interact by a logarithmic potential. The long and short distance features of the effective potential --the free energy of the system for a given distance between Q and the disk-- are worked out analytically in detail. They crucially depend on the sign of Q/q, and on the global charge borne by the discotic complex, that can vanish. While most results are obtained at the intermediate coupling Gamma = beta q^2 = 2 (beta being the inverse temperature), we have also investigated situations with stronger couplings: Gamma=4 and 6. We have found that at large distances, the sign of the effective force reflects subtle details of the charge distribution on the disk, whereas at short distances, polarization effects invariably lead to effective attractions.

description: The purpose of this investigation was to determine if there is a difference in the type of microorganisms found in oral sites classified as gingival health, mild-moderate periodontitis, or severe periodontitis as measured by the DMDx* Test. A purposive sample of one hundred oral sites was selected from adult patients. Subjects were excluded from the study based on: the presence of any systemic disorders, communicable diseases, diabetic conditions, blood dyscrasias, congenital heart disease, rheumatic heart disease, pregnancy, history of periodontal surgery, prosthetic joint replacement, hypertensive heart disease, or any medications that might alter the gingival tissues (e.g. antibiotics, hormonal therapy, oral contraceptives, etc.). A clinical oral examination was conducted on patients to identify oral sites that could be classified as healthy tissue, mild to moderate periodontitis, and advanced periodontitis. Once classified, the DMDx* Test was conducted. Results revealed significant differences in Porphyromonas gingivalis between sites of gingival health and mild-moderate periodontitis and between gingival health and severe periodontitis. The quantity of Porphyromonas gingivalis was greatest in mild-moderate periodontitis, followed by severe periodontitis. Levels of Prevotella intennedia were significantly different among all three periodontal classifications, with the highest concentration in sites of mild-moderate periodontitis and the lowest concentration in gingival health. In all classification groups, the levels of Prevotella intennedia were the highest, followed by Porphyromonas gingivalis, and Haemophilus actinomycetemcomitans.

Findings support the conclusion that Haemophilus actinomycetemcomitans is a poor indicator for active adult periodontal disease. Porphyromonas gingivalis and Prevotella intennedia are most prevalent in oral sites classified as mild-moderate to severe periodontal disease.

description: Signal detection theory (SDT) parameters can describe a learner's ability to discriminate (d') normal from abnormal and the learner's criterion (λ) to under or overcall abnormalities. To examine the serial changes in SDT parameters with serial exposure to radiological cases. 46 participants were recruited for this study: 20 medical students (MED), 6 residents (RES), 12 fellows (FEL), 5 staff pediatric emergency physicians (PEM), and 3 staff radiologists (RAD). Each participant was presented with 234 randomly assigned ankle radiographs using a web-based application. Participants were given a clinical scenario and considered 3 views of the ankle. They classified each case as normal or abnormal. For abnormal cases, they specified the location of the abnormality. Immediate feedback included highlighting on the images and the official radiologist's report. The low experience group (MED, RES, FEL) showed steady improvement in discrimination ability with each case, while the high experience group (PEM, RAD) had higher and stable discrimination ability throughout the exercise. There was also a difference in the way the high and low experience groups balanced sensitivity and specificity (λ) with the low experience group tending to make more errors calling positive radiographs negative. This tendency was progressively less evident with each increase in expertise level. SDT metrics provide valuable insight on changes associated with learning radiograph interpretation, and may be used to design more effective instructional strategies for a given learner group.
The English the 'their' Indians: English claims to early colonial New York under Governor Thomas Dongan, 1682-88

description: Bibliography: p. 85-94
description: In 1682 Thomas Dongan became governor of the English colony of New York. His administration was plagued by territorial disputes with the nearby colony of New France. These conflicts were intensified by the presence of the Iroquois Indians. This thesis demonstrates how the English crown and governor Dongan used the Iroquois to strengthen and expand their claims to land in and surrounding New York. It describes how Dong an used the Iroquois to find a balance between the centre's ideas of sovereignty and the ability to apply these ideas to the periphery of his colony. Through the use of correspondences between the English crown, the French, and New York this thesis describes how and why the Iroquois fit into certain European notions of sovereignty and possession. By adapting their views of sovereignty and possession to include the indigenous peoples, Europeans were able to strengthen their claims over North America.

description: Baba Dioum, an African environmental champion said: "In the end, we will conserve only what we love, we will love only what we understand, and we will understand only what we are taught." How do we teach, help persons to understand, and to practice conservation? Puppetry is a communication and art form from many regions of the world including eastern and western cultures, Native Americans, and on Sesame Street. Radical puppets are used with adults for social change. Puppets entertain, communicate, and people relate to them with less intimidation. Puppet Jedediah Johnston, a historical mountain man, tells stories of the Congress and area bridging history, the present, and future together better than humans because he has no temporal or spatial limits. He can discuss balancing wildlife management and landowner livelihoods without biases that could be associated with humans. Children build unique relationships with puppets and communicate through them. Through the use of puppets and role-playing, children express points of view that are not necessarily their own. This process develops a deeper understanding of their issues, provides an opportunity for reasoning rather than recall, and allows learners to share authority and to assume responsibility for their learning. Research indicates puppets have positive effects on children's motivation and engagement in learning. This offers hope that children and adults can be motivated to develop environmental values and to become stewards who will manage the diversity and wonders of nature. Puppets are tools to broaden understanding. With understanding, there can be more effective actions.

description: Choosing to travel as a passenger can reduce negative impacts of congestion. However, the decision to be a passenger is complex. The researcher hypothesizes that social norms and expected roles related to gender, age, income and relationships in social networks - relative to travel times and costs - have large influences on passenger mode choice behaviour. A stated preference survey was conducted in Calgary to investigate these elements. The results showed that travel time and cost, age, gender, and income, the type of relationship to the driver as well as imposing extra travel time on the driver have statistically significant influences in passenger options utility. Children showed little concern towards imposing additional travel times on parents whereas young men showed strong concern towards such imposition on their friends. This established the importance of perceived roles and social norms that can limit the ability to encourage ridesharing using small monetary incentive.

description: Homelessness, rape, partner abuse and other violent events associated with psychological distress are common occurrences in the lives of street sex workers and have not been considered in their impact on developing HIV prevention programs. Feelings of stigmatization due to the nature and illegal status of the occupation are likely to contribute to significant psychological distress. Psychological distress and drug dependency may, in turn, undermine the motivation and ability of sex workers to adopt safer sex behavior. Most HIV programs targeted to this population tend to ignore the multiple factors that are associated with sex work. Mental health and other basic services such as drug abuse treatment, public assistance, housing, education, and training for alternative employment are not integrated into HIV prevention approaches. Moreover, most HIV prevention programs for female sex workers are not culturally sensitive and fail to involve sex workers in designing an intervention reflective of the community's unique needs or infrastructure.

description: A qualitative exploratory case study was designed to gain insight into the nature and essence of an expert gifted program teacher's conception of perfectionism and reflective practice, and its influence on gifted (high ability) student perfectionist behaviour. One expert teacher and five grade 12 students were observed and interviewed. The expert teacher's ideas about perfectionism and learning environment were examined, using Collin's (2005) Cognitive Apprenticeship model (similar to traditional, but rather, cognitive training) and Abstract Replay method (reflection on audio-video-recorded classroom observations). As the complex dynamic unfolded among participant actions and interactions, while examining perfectionism, the findings were compared to the relevant literature concerning conceptions of perfectionism and perfectionist behaviour. No previous research explored this topic and the results far surpassed researcher predictions concerning perfectionism and anxiety among students in a congregated gifted program setting. Three problems/issues/gaps were found in the field. The first was a dissonance regarding a predominantly negative conception of perfectionism, based on mostly clinical examinations of adults. Second, perfectionism is often heightened in gifted students and their needs - often underserved and/or neglected (Adelson, 2007; Piechowski, 2006; Siegle & Schuler, 2000). Third, gifted students are typically capable of perfect/excellent performances in strength area/s, however, without the required expertise - can become frustrated, at best. The results are consistent with Durkheim's (1983) theory of knowledge, Argyris and Schon's (1974) theory in use, reflection-in-action and on-action, and Hamachek's multi-dimensional construct of perfectionism - with behaviours and outcomes from healthy to unhealthy. The results revealed the following proposition. To thrive, some gifted students need an ideal/effective learning environment or congregated gifted program, like the expert teacher's examined in this study. The expert teacher participant understands and anticipates healthy and unhealthy perfectionism, models and enhances healthy and prevents or diminishes unhealthy perfectionist behaviour and outcomes.

description: Gas hydrates which form at high pressure and low temperature conditions, are solid crystalline compounds comprised of a lattice of water molecules that encage gas molecules. Gas hydrates impact society because of their potential as an immense energy source and their role in submarine geohazards. Economical production of natural gas from hydrate reservoirs crucially depends on the formation permeability and the relative permeability of the sediment to fluid flow. Permeability measurements from natural core samples are difficult owing to core disturbance during retrieval and processing. Laboratory synthesized samples provides a viable alternative with the flexibility to form samples with desired morphology and mineralogy. Unfortunately, very few permeability and relative permeability measurements have been performed and thus the range of media properties and saturations expected in natural hydrate bearing sediments is not available. In the absence of reliable experimental data, numerical reservoir simulators employ theoretical models for permeability prediction. However, experimental verification of the theoretical models is still required. This thesis focuses on understanding the effect of hydrate formation on the relative permeability of porous media to fluid flow. In doing so, a better way to evaluate the suitability of the existing theoretical models has been developed. It also explores if better permeability prediction can be achieved using a combination of available theoretical models. Finally, an experimental program in which relative permeability of porous media in the presence of carbon dioxide hydrate was performed and the results analyzed within the proposed framework of modeling and evaluating theoretical permeability predictions.

Creators: name: Sunikka, Anne
Publisher: name: Zenodo
Year: 2019
Subjects: Research Data Management, Open Science and Research initiative, Finland, Aalto University, research support

description: This paper describes how the Finnish Ministry of Education and Culture launched an initiative on research data management and open data, open access publishing, and open and collaborative ways of working in 2014. Most of the universities and research institutions took part in the collaborative initiative building new tools and training material for the Finnish research needs. Measures taken by one university, Aalto University, are described in detail and analysed, and compared with the activities taking place in other universities.

The focus of this paper is in the changing roles of experts at Aalto University, and organisational transformation that offers possibilities to serve academic personnel better. Various ways of building collaboration and arranging services are described, and their benefits and drawbacks are discussed.

The paper was presented in International Data Curation Conference (IDCC 2019) in Melbourne, Australia, 4 - 7 February, 2019.

description: Cable supported bridges have been used around the world for several years due to their advantage to overcome large spans, efficiency, aesthetics and ease of construction. Several studies have been made on this kind of bridge structure, including dynamic analyses to understand the structural behavior of the bridge. Extradosed bridges, a concept of partially cable-supported bridges, started to be used since the 1990's mainly in Japan, and although their use has increased in the past several years, no major studies have been made on their dynamic behavior. The purpose of this thesis is to provide insight into how different support conditions such as integral abutments, deep foundations and soil properties influence the dynamic structural behaviour of the bridge elements such as the cables, towers and bridge deck. A time history analysis with the Northridge earthquake is performed for the longitudinal, transverse and vertical direction. A 30 finite element model and analysis was performed using SAP2000 software (Static and Dynamic Finite Elements Analysis of Structures Advanced 14.1). The results for each bridge, for different support conditions, are presented in order to understand the dynamic response of the structure.
