A tunnel of hope : the experiences of student-mothers in a community college based developmental studies program
Creators: name: McGee Thompson, Donna Jean
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this research was to investigate the experiences of mothers of young children attending a community college-based Developmental Education (DVST) program. A literature review indicated three general notions: 1) mothering in North America today is all-consuming and associated with numerous contradictions and difficulties, 2) student mothers in a variety of post-secondary contexts face difficulties participating, and 3) some DVST students may experience some level of "culture shock" upon entering post-secondary education. Participants were eight women enrolled in the program while assuming the primary live-in parenting responsibility for at least one child under thirteen. Semi-structured interviews and subsequent analysis of interview transcripts revealed six themes. Participation in the DVST program as a student-mother (1) signifies a major life turning point, (2) is a positive experience, (3) involves adapting to new time pressures, (4) involves redefining roles in relationships with children and other family members, which can lead to feelings of guilt, (5) is vulnerable to childcare and financial crises, and (6) is best supported by services related to childcare, financial assistance, and connections with women in like circumstances. The results of this study have implications for daycare policy, career counselling, centralized services for student-mothers receiving income assistance, support networks, and DVST instructors' role in establishing linkages between student-mothers and the college community.

description: Despite having the second largest livestock population in Africa and favorable climate, the contribution of the livestock, especially the dairy sector to the Ethiopian economy is minimal. The per capita consumption of dairy products of 16 liters is one of the lowest in the world. With increasing income and urbanization, the demand for dairy products is expected to increase. A number of studies have examined the potential of the dairy sector to satisfy existing as well as future demand for dairy products. Most of the studies, however, focus on technological constraints such as poor genotype of indigenous animals, tropical animal diseases, availability of feed and other related services and recommend costly technological solutions aimed to alleviate those constraints. Yet there is evidence of inefficiency and significant post harvest losses of milk. We used a Cobb- Douglas stochastic production function to analyze the inefficiencies of a random sample of 74 smallholder dairy farmers in the Central Ethiopian Highlands. Results show that forage and concentrate feed, number of cross breed cows and expenditures on veterinary services are significant determinants of milk output. We also found evidence of systematic inefficiency in dairy production associated with farmers' educational level and livestock training that explains almost 90% of the variation in milk production. The average efficiency score of farmers in the sample is 79%. Thus milk output can be increased on average by 21% with existing technology by training farmers in modern management practices in feeding, calving, milking, storing, processing and marketing.

description: The changes recently introduced in the EU Common Market Organization for sugar will interact with preferential imports from developing countries and least developed countries that enjoy preferential treatment for exports to the EU, as well as by trade and adjustment costs. This paper focuses on the impact of the EU Commission's sugar policy reform and the Everything But Arms initiative on the African, Caribbean and Pacific countries and the Least Developed Countries. Simulations are run with an empirical model structure comprising a partial equilibrium model for the world sugar market and a gravity model to replicate least developed countries bilateral trade with Europe. Particularly, the gravity approach is employed to model the abolition of import tariffs for sugar originating in least developed countries, subject to trade costs, while the partial equilibrium approach is employed to assess the effects of EU Commission's sugar policy reform and the Everything But Arms initiative on world markets. Results suggest that the African, Caribbean and Pacific countries will experience significant reduction in their export revenue, whilst the initial impact on least developed countries may be limited but increasing in the medium run.

description: We present a data-driven approach for the prediction of the electric dipole moment of diatomic molecules, which is one of the most relevant molecular properties. In particular, we apply Gaussian process regression to a novel dataset to show that dipole moments of diatomic molecules can be learned, and hence predicted, with a relative error <5%. The dataset contains the dipole moment of 162 diatomic molecules, the most exhaustive and unbiased dataset of dipole moments up to date. Our findings show that the dipole moment of diatomic molecules depends on atomic properties of the constituents atoms: electron affinity and ionization potential, as well as on (a feature related to) the first derivative of the electronic kinetic energy at the equilibrium distance.

description: For quite a while, stated preferences have been a major tool to measure consumer preferences for new products and services. Revealed preference methods, in particular experimental economics, have gained popularity recently because they have been shown to be more incentive compatible, and therefore more accurate. However, this advantage comes at the expense of higher survey costs. In the developing countries with limited funding for research, it is important to determine whether the extra cost can be justified by the extra gain in accuracy. A survey of 100 farmers was carried out in Western Kenya to determine consumer preference for yellow maize using the contingent valuation, choice experiments and experimental auction methods. Experimental auctions produced the most realistic results for mean willingness to pay. They are also the most accurate at all budget levels, but also the most expensive. Considering their accuracy and realistic results, we conclude that they should be the recommended method in measuring consumer preference in developing countries, since the extra cost is more than recovered by the gain in accuracy.

description: Axionic cosmic string solutions are investigated in a superstring motivated model with a pseudo-anomalous U(1) gauge symmetry. The inclusion of a gauge field and spatially varying dilaton allow local defect solutions with finite energy per unit length to be found. Fermion zero modes (whose presence is implied by supersymmetry) are also analysed. The corresponding fermion currents suggest strong cosmological bounds on the model. It is shown that the unusual form of the axion strings weakens these bounds. Other cosmological constraints on the underlying theory are also discussed.

SHM Racer : dynamic race condition detection using shared memory traps

description: This project investigated different types of data races that can exist within C code, and then incrementally built a race condition detector, SHM Racer, using an assortment of thread safety violation/data race violation detection methods. The objective of this report was to demonstrate the tradeoffs/benefits of certain race condition finding tools, and construct a tool that could minimize false positive race errors while maximizing the number of found data races. Race condition detection using static analysis can log false positives/false negatives due to a missed understanding of complex synchronization patterns. Dynamic analysis can often minimize false positives, but its ability to slow runtime performance can make this type of analysis impractical. The decided approach was to develop SHM Racer: a shared memory library that provides a shared memory access interface to multiple threads. SHM Racer would also use its knowledge of thread contexts and near-miss analysis data to dynamically modify its shared memory response performance with the intent of expanding critical sections. The aim of this approach was to increase the likelihood of race condition occurrence without significantly altering runtime performance. Test observations demonstrated that while expanding critical sections does increase the probability of detecting data races without producing false positives, there are significant performance/race condition detection impacts if the critical sections are expanded without accommodating for happens-before and already found race errors. Using a combination of near miss analysis and dangerous pair pruning, there was an observable performance improvement in analyzed code performance. However, while there were no false positives detected by SHM Racer, there were still missed race violations due to the tool’s effects on thread synchronization patterns. Even though SHM Racer did miss finding race violations, its false positive minimization and configurable delay thresholds make it very effective at catching basic data races without having to learn synchronization patterns.

description: This is a noncommutative-geometric study of the semiclassical dynamics of finite topological D-brane systems. Starting from the formulation in terms of A -infinity categories, I show that such systems can be described by the noncommutative symplectic supergeometry of Z2-graded quivers, and give a synthetic formulation of the boundary part of the generalized WDVV equations. In particular, a faithful generating function for integrated correlators on the disk can be constructed as a linear combination of quiver necklaces, i.e. a function on the noncommutative symplectic superspace defined by the quiver's path algebra. This point of view allows one to construct extended moduli spaces of topological D-brane systems as non-commutative algebraic `superschemes'. They arise by imposing further relations on a Z2-graded version of the quiver's preprojective algebra, and passing to the subalgebra preserved by a natural group of symmetries.

description: We investigated the double-exchange spin ice model on a kagomé lattice by Monte Carlo simulation in order to study a mechanism for lifting the degeneracy in frustrated electron systems. We show specific heat and vector spin chirality data on a finite lattice. Specific heat has a double-peak structure: A broad peak and a sharp peak are at $k_{\rm B}T/t \sim 0.15$ and 0.015, respectively, where $t$ is the transfer integral of electrons. The broad peak corresponds to a crossover to the spin ice-like state, on the other hand, the sharp one a transition to a dodecagonal spin cluster (dodecamer) state. We discuss the interplay between the formation of the dodecamer state and the lifting of the macroscopic degeneracy.

Education limited : framing possibilities and constraints of online teaching in a university course

Publisher: name: University of British Columbia

description: How much influence and control do instructors have when they teach online? How creative can they be and what limits do they encounter? Teaching via the internet can be a creative and engaging process that allows for innovative approaches to learning for students from all over the world. It can also be a challenging setting for instructors and students to teach and learn. This study investigated how instructional processes in an internet-based course were shaped by factors beyond the instructor's control? Frame factor theory was used as the conceptual framework to identify and analyze factors that shape instruction. The unique contribution of this study is to examine an online setting. Thus, most of this research is about how institutional and technological frames shape teaching. Documents were analyzed from an online graduate course to identify and analyze frame factors. Policy documents of a distance teaching unit, course design documents and the archived course discussion forum were examined. The research indicates that class size, instructor role and accountability, the assessment criteria, course content and methods of teaching online were all factors decided by the host organization before an instructor began teaching. Technological factors also shaped instruction beyond an instructors control, including: the technology required to access the course, place-independent access to the course, the nature of asynchronous communication and the nature of text-based communication. Text-based asynchronous communication highlighted students writing styles, allowed for the use of quotes and references, allowed for thoughtful, reflective communication but also created concerns about lurkers and workload. These findings from the research were used to create an analytical framework, a tetrad, conceived as a series of questions. The questions are meant to guide decision-making by instructors and planners of internet-based courses. The four questions are: 1) What teaching decisions does the organization make before you, the instructor, begin the class? 2) How will the technology affect people's participation level and their quality of interaction? 3) How much accountability is 'built-in' to the communication? 4) How labour-intensive is the medium? The tetrad has been conceived so it may be applicable to all internet-based teaching, even as the medium continues to change.

description: We describe a new numerical scheme for MHD which combines a higher order Godunov method (PPM) with Constrained Transport. The results from a selection of multidimensional test problems are presented. The complete test suite used to validate the method, as well as implementations of the algorithm in both F90 and C, are available from the web. A fully three-dimensional version of the algorithm has been developed, and is being applied to a variety of astrophysical problems including the decay of supersonic MHD turbulence, the nonlinear evolution of the MHD Rayleigh-Taylor instability, and the saturation of the magnetorotational instability in the shearing box. Our new simulations of the MRI represent the first time that a higher-order Godunov scheme has been applied to this problem, providing a quantitative check on the accuracy of previous results computed with ZEUS; the latter are found to be reliable.

description: This study investigates the impacts of access to inventory credit (warrantage), input supply shops, fertilizer micro-dosing demonstrations, and other factors on farmers' use of inorganic and organic fertilizer in Niger, and the impacts on crop yields. We find that access to warrantage and input shops and participation in fertilizer micro-dosing demonstrations have increased use of inorganic fertilizer. Access to off-farm employment and ownership of traction animals also contribute to use of inorganic fertilizer. Use of organic fertilizer is less affected by these factors, but is substantially affected by the household's crop mix, access to the plot, ownership of durable assets, labor and land endowments, and participation in farmers' associations. Land tenure influences both inorganic and organic inputs, with less of both on sharecropped and encroached plots. Inorganic fertilizer has a positive impact on millet yields, with an estimated marginal value-cost ratio greater than 3, indicating significant profitability. Organic fertilizer has a positive impact on millet-cowpea yields. We find little evidence of complementarity between inorganic and organic fertilizer. Since warrantage, input supply shops and fertilizer micro-dosing demonstrations increase use of inorganic fertilizer which in turn increases millet yields, these interventions indirectly increase millet yields, although the impacts are relatively small. These findings support promoting increased input use through promotion of inventory credit, input supply shops and fertilizer micro-dosing demonstrations. Other interventions that could help to boost productivity include promotion of improved access to farm equipment and traction animals and improved access to land under secure tenure.

description: Experiments and simulations have been performed to examine the finite-temperature behavior of Ga$_{17}{}^{+}$ and Ga$_{20}{}^{+}$ clusters. Specific heats and average collision cross sections have been measured as a function of temperature, and the results compared to simulations performed using first principles Density--Functional Molecular--Dynamics. The experimental results show that while Ga$_{17}{}^{+}$ apparently undergoes a solid--liquid transition without a significant peak in the specific--heat, Ga$_{20}{}^{+}$ melts with a relatively sharp peak. Our analysis of the computational results indicate a strong correlation between the ground--state geometry and the finite--temperature behavior of the cluster. If the ground--state geometry is symmetric and "ordered" the cluster is found to have a distinct peak in the specific--heat. However, if the ground--state geometry is amorphous or "disordered" the cluster melts without a peak in the specific--heat.

description: A full quantum treatment of coherent population trapping (CPT) is given for a system of resonantly coupled atoms and electromagnetic field. We develop a regular analytical method of the construction of generalized dark states (GDS). It turns out that GDS do exist for all optical transitions $F_g\to F_e$, including bright transitions $F\to F+1$ and $F''\to F''$ with $F''$ a half-integer, for which the CPT effect is absent in a classical field. We propose an idea to use an optically thick medium with a transition $F''\to F''$ with $F'' \ge 3/2$ a half-integer as a ''quantum filter'', which transmits only a quantum light.

description: 今日,スマートフォンの普及により,Youtube やニコニコ動画などの動画共有 サービスが人気を博している.これらの影響によって人々が動画を編集する機会 が増加し,動画編集を支援するアプリケーションも普及した.より良い動画を作 成するためには,バックグラウンドミュージック(BGM)の付与は必要不可欠だ ろう.しかしこのようなアプリケーションを用いても,使用する楽曲は自身で探 す必要がある. 自動作曲のアプローチは様々なものがあり,動画を基に自動作曲を行う研究も ある.動画から自動作曲では色や動きなどの動画特徴量と調やコードなどの音楽 特徴量に対して適切な対応付けをすることで楽曲生成をするがこれは必ずしも簡 単ではない. 本稿では既存研究で触れられていなかった動画の盛り上がりと楽曲の盛り上が りの対応付けを行うことで楽曲生成を行う.まず,動画の盛り上がり度の時間軌 跡を取得し,その時間軌跡からテクノミュージックの自動生成を行う.動画の盛り 上がり度の時間軌跡取得では動画のフレーム間での画素の動きを特徴量として抽 出する.動画の対してモーションテンプレート解析を行い,動画の躍動の度合い を求め,盛り上がり度を推定する.推定した盛り上がり度をできるだけ再現する ように,隠れマルコフモデル(HMM)を用いてループシーケンサに挿入する音素 材を決定する.ただし,楽曲の始まりから終わりまで同じ HMM を用いると,テ クノ特有の楽曲構成を再現できないため,テクノの楽曲構成を考慮して HMM の パラメータを使い分ける. 以上の処理を実現したシステムの実装を行い評価実験を行ったところ,動画の 対応については 7 段階中 4.86,自然なテクノミュージック生成については 7 段階 中 4.60 となり,楽曲構成を考慮しない手法と比較したところ,10 種類の動画に楽 曲を付与する実験を行ったところ,楽曲が動画との盛り上がりと合致しているか は 7 曲,自然なテクノミュージックになったか 6 曲において,楽曲構成を考慮しな い場合に比べて高評価が得られた.

description: In the paper we considere three state $p$-adic Potts model with competing interactions on a Cayley tree of order two. We reduce a problem of describing of the $p$-adic Gibbs measures to the solution of certain recursive equation, and using it we will prove that a phase transition occurs if and only if $p=3$ for any value (non zero) of interactions. As well, we completely solve the uniqueness problem for the considered model in a $p$-adic context. Namely, if $p\neq 3$ then there is only a unique Gibbs measure the model.

description: Food safety issues are becoming more important in international trade. Fresh food products are more likely to carry food risks and to encounter Sanitary and Physiosanitary Measures (SPS) as barriers to market access. Developing countries (DC) need to overcome barriers and develop capability to guarantee the safety of food product exports in order to maximize benefits from international trade. The paper examines the importance of agro-food processing sector for developing countries and explores the private and public actions required to address food safety risks in fresh food product exports from developing countries. Thus DC exporters must learn to supply safe products and to defend their interest in transparent, science-based standards. Successful export market development will also require public actions by DC governments. Such actions may include research to improve production methods, testing and certification of product, implementation of new regulation, negotiating pre-certificate by importer governments, and participation in international negotiations regarding SPS measures.

description: Traditional cultural landscapes are of special value not only for reasons of nature conservation and high species diversity but also because they intersect with the identity of local communities, support recreation and tourism, and preserve cultural heritage. Structural changes in rural areas threaten these unique sceneries and environments in Europe and worldwide. As a result, the question of how to maintain and manage cultural landscapes where economic benefits are not assured has become a priority in science and in practice. Considering this context, community-based collaborative landscape management (CLM) can be considered an innovative and promising approach. This paper presents results from a stakeholder analysis examining the preconditions and opportunities for initiating a CLM in the biosphere reserve known as ‘Spreewald’. The results indicate that due to the type of problem (landscape change)—which is characterised by complexity, beneficial linkages to a multitude of actor groups, and broad problem awareness—CLM appears to be feasible. However, other preconditions related to social relationships among actor groups, questions of legitimate coordination and the collaborative capacity of the community are not met, thus reducing the likelihood of success. To address these challenges, we discuss the potential of transdisciplinary processes (TD) to assist local communities in establishing such a collaborative problem-solving and management approach. We show that TD is highly valuable and supportive during this critical stage of emerging collaboration.

description: We present the first-ever lattice computation of pi pi-scattering in the I=1 channel with Nf=2 dynamical quark flavours obtained including an ensemble with physical value of the pion mass. Employing a global fit to data at three values of the pion mass, we determine the universal parameters of the rho-resonance. We carefully investigate systematic uncertainties by determining energy eigenvalues using different methods and by comparing inverse amplitude method and Breit-Wigner type parametrizations. Overall, we find mass 786(20) MeV and width 180(6) MeV, including statistical and systematic uncertainties. In stark disagreement with the previous Nf=2 extrapolations from higher than physical pion mass results, our mass value is in good agreement with experiment, while the width is slightly too high.

Crossover of dynamical instability and chaos in the supercritical state

description: We calculate the maximal Lyapunov exponent for a bulk system of 256 Lennard-Jones particles in constant energy molecular dynamics simulations deep into the supercritical state. We find that the maximal Lyapunov exponent undergoes a crossover, and that this crossover coincides with the dynamical crossover at the Frenkel line from liquid physics. We explain this crossover in terms of two different contributions to dynamical instability: diffusion in the liquid-like state below the Frenkel line, and collisions in the gas-like state above. These results provide insight into the phase space dynamics far from the melting line and densities where rare-gas approximation are inapplicable.

"It’s not about being male, it’s about being cool" : a case study of male peer sexual health educators
Creators: name: Ripley, Lu
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines the cultural norms relating to gender, sexuality and race in the work and lives of male youth educators who volunteer with Condomania, a Vancouver based sexual health promotion program. A qualitative, case study action-oriented methodology was utilized. Individual interviews and a focus group were conducted with 7 male sexual health educators from the Condomania program over a one-year period. The researcher was also coordinator of the program, and integrated observations and self-reflection during the process of this project. Aspects of educators' subjectivities, such as maleness, whiteness and sexual identity are explored. The thesis suggests that although it is essential to foreground males in the development and execution of programs that deal with issues such as sexual health, the process of doing so is not uncomplicated. Contradictions and tensions emerged throughout this study in how the participants perceived, viewed and took up gender and sexuality in the classroom and their own lives, demonstrating concurrently the hegemony and instability of heterosexual masculinity.

Quantum control limited by quantum decoherence

description: We describe quantum controllability under the influences of the quantum decoherence induced by the quantum control itself. It is shown that, when the controller is considered as a quantum system, it will entangle with its controlled system and then cause quantum decoherence in the controlled system. In competition with this induced decoherence, the controllability will be limited by some uncertainty relation in a well-armed quantum control process. In association with the phase uncertainty and the standard quantum limit, a general model is studied to demonstrate the possibility of realizing a decoherence-free quantum control with a finite energy within a finite time. It is also shown that if the operations of quantum control are to be determined by the initial state of the controller, then due to the decoherence which results from the quantum control itself, there exists a low bound for quantum controllability.

The Topological Symmetric Orbifold

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We analyse topological orbifold conformal field theories on the symmetric product of a complex surface M. By exploiting the mathematics literature we show that a canonical quotient of the operator ring has structure constants given by Hurwitz numbers. This proves a conjecture in the physics literature on extremal correlators. Moreover, it allows to leverage results on the combinatorics of the symmetric group to compute more structure constants explicitly. We recall that the full orbifold chiral ring is given by a symmetric orbifold Frobenius algebra. This construction enables the computation of topological genus zero and genus one correlators, and to prove the vanishing of higher genus contributions. The efficient description of all topological correlators sets the stage for a proof of a topological AdS/CFT correspondence. Indeed, we propose a concrete mathematical incarnation of the proof, relating Gromow-Witten theory in the bulk to the quantum cohomology of the Hilbert scheme on the boundary.
