Investigating complex-value-based community mine education strategies : a case study with the Tlicho community in the Wek’eezhii region Northwest Territories, Canada
Creators: name: Chouinard, Rebecca Rose
Publisher: name: University of British Columbia
Year: 2009

description: This thesis attempts to define an effective model for developing educational programs related to mining for communities in an iterative manner that speaks to the needs and values of the community. The lessons learned provide direction on methods to replicate an effective education program for communities. The success of a process that was used to develop an education program in a mining context for a particular case has been evaluated. Reasons for why learning does or does not transpire for this case were explored. A case study of the Tlicho community in Canada’s Northwest Territories was conducted to investigate this query. A combination of theories, approaches, and methods were utilized in the development of the education program, the collection and interpretation of data, and the formation of key findings. The inquiry led to the following four key conclusions: 1) Knowledge and understanding are effectively acquired by situating information as primary experiences or through oral accounts by persons who have experienced. 2) The objects of learning for education programs must be valuable, useful, and meaningful to the intended learners. Each individual must be given the autonomy to decide what topics or concepts are appropriate for him or her. Thus, choice and flexibility must be built into the programs. The “I am going to teach you...” approach to education is less superior than a humble humanistic approach to education. 3) The process to develop programs should involve cycles of action and reflection, input from the intended learners, and repetition. 4) Assimilation of information occurs through the experience of knowledge that is presented in culturally based frames informed by particular stories, experiences, teachers, places, values, histories, and materials. These conclusions provide some insight on how governments and mining companies can and should engage with communities to learn. Enhanced knowledge and understanding through learning by communities, governments, and mining companies, strengthen relationships and agreements. When everybody’s knowledge and understanding improves, better decisions can be made.
Measurement of the t t-bar Production Cross Section in pp Collisions at 7 TeV in Lepton + Jets Events Using b-quark Jet Identification
Creators: name: CMS Collaboration

Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A new measurement of the inclusive production cross section for pp to t t-bar is performed at a center-of-mass energy of 7 TeV using data collected by the CMS experiment at the LHC. The analysis uses a data sample corresponding to an integrated luminosity of 36 inverse picobarns, and is based on the final state with one isolated, high transverse momentum muon or electron, missing transverse energy, and hadronic jets. The ttbar content of the selected events is enhanced by requiring the presence of at least one jet consistent with b-quark hadronization. The measured cross section is 150 +/- 9 (stat.) +/- 17 syst.) +/- 6 (lumi.) pb and is in agreement with higher-order QCD calculations. The combination of this measurement with a previous CMS result based on dileptons gives 154 +/- 17 (stat.+syst.) +/- 6 (lumi.) pb.

description: The recursive least-squares (RLS) algorithm has well-documented merits for reducing complexity and storage requirements, when it comes to online estimation of stationary signals as well as for tracking slowly-varying nonstationary processes. In this paper, a distributed recursive least-squares (D-RLS) algorithm is developed for cooperative estimation using ad hoc wireless sensor networks. Distributed iterations are obtained by minimizing a separable reformulation of the exponentially-weighted least-squares cost, using the alternating-minimization algorithm. Sensors carry out reduced-complexity tasks locally, and exchange messages with one-hop neighbors to consent on the network-wide estimates adaptively. A steady-state mean-square error (MSE) performance analysis of D-RLS is conducted, by studying a stochastically-driven `averaged' system that approximates the D-RLS dynamics asymptotically in time. For sensor observations that are linearly related to the time-invariant parameter vector sought, the simplifying independence setting assumptions facilitate deriving accurate closed-form expressions for the MSE steady-state values. The problems of mean- and MSE-sense stability of D-RLS are also investigated, and easily-checkable sufficient conditions are derived under which a steady-state is attained. Without resorting to diminishing step-sizes which compromise the tracking ability of D-RLS, stability ensures that per sensor estimates hover inside a ball of finite radius centered at the true parameter vector, with high-probability, even when inter-sensor communication links are noisy. Interestingly, computer simulations demonstrate that the theoretical findings are accurate also in the pragmatic settings whereby sensors acquire temporally-correlated data.

description: We introduce and compute a 2-parameter family deformation of the A-polynomial that encodes the color dependence of the superpolynomial and that, in suitable limits, reduces to various deformations of the A-polynomial studied in the literature. These special limits include the t-deformation which leads to the "refined A-polynomial" introduced in the previous work of the authors and the Q-deformation which leads, by the conjecture of Aganagic and Vafa, to the augmentation polynomial of knot contact homology. We also introduce and compute the quantum version of the super-A-polynomial, an operator that encodes recursion relations for S^r-colored HOMFLY homology. Much like its predecessor, the super-A-polynomial admits a simple physical interpretation as the defining equation for the space of SUSY vacua (= critical points of the twisted superpotential) in a circle compactification of the effective 3d N=2 theory associated to a knot or, more generally, to a 3-manifold M. Equivalently, the algebraic curve defined by the zero locus of the super-A-polynomial can be thought of as the space of open string moduli in a brane system associated with M. As an inherent outcome of this work, we provide new interesting formulas for colored superpolynomials for the trefoil and the figure-eight knot.

description: We describe the Herschel Virgo Cluster Survey (HeViCS) and the first data that cover the complete survey area (four 4 x 4 deg2 regions). We use these data to measure and compare the global far infrared properties of 78 optically bright galaxies that are selected at 500 \mum and detected in all five far-infrared bands. We show that our measurements and calibration are broadly consistent with previous data obtained by IRAS, ISO, Spitzer and Planck. We use SPIRE and PACS photometry data to produce 100, 160, 250, 350 and 500 \mum cluster luminosity distributions. These luminosity distributions are not power laws, but peaked, with small numbers of both faint and bright galaxies. We measure a cluster 100-500 micron far-infrared luminosity density of 1.6(7.0) \pm 0.2 x 10^9 Lsun/Mpc3. This compares to a cluster 0.4-2.5 \mum optical luminosity density of 5.0(20.0) x 10^9 Lsun/Mpc3, some 3.2(2.9) times larger than the far-infrared. A typical photon originates from an optical depth of 0.4\pm0.1. Most of our sample galaxies are well fitted by a single modified blackbody (beta=2), leading to a mean dust mass of log Mdust = 7.31 Msun and temperature of 20.0 K. We also derive both stellar and atomic hydrogen masses from which we calculate mean values for the stars:gas(atomic) and gas(atomic): dust mass ratios of 15.1 and 58.2 respectively. Using our derived dust, atomic gas and stellar masses we estimate cluster mass densities of 8.6(27.8) x 10^6, 4.6(13.9) x 10^8, 7.8(29.7) x 10^9 Msun/Mpc3, respectively for dust, atomic gas and stars. These values are higher than those derived for field galaxies by factors of 39(126), 6(18) and 34(129) respectively. In the above luminosity/mass densities are given using the whole sample with values in brackets using just those galaxies that lie between 17 and 23 Mpc. We provide a data table of flux densities in all the Herschel bands for all 78 bright Virgo cluster galaxies.

description: We present near-infrared spectroscopic observations of star-forming galaxies at z~1.4 with FMOS on the Subaru Telescope. We observed K-band selected galaxies in the SXDS/UDS fields with K<23.9 mag, 1.210^{9.5} Msun, and expected F(Halpha)>10^{-16} erg s^{-1} cm^{-2}. 71 objects in the sample have significant detections of Halpha. For these objects, excluding possible AGNs identified from the BPT diagram, gas-phase metallicities are obtained from [NII]/Halpha line ratio. The sample is split into three stellar mass bins, and the spectra are stacked in each stellar mass bin. The mass-metallicity relation obtained at z~1.4 is located between those at z~0.8 and z~2.2. We constrain an intrinsic scatter to be ~0.1 dex or larger in the mass-metallicity relation at z~1.4; the scatter may be larger at higher redshifts. We found trends that the deviation from the mass-metallicity relation depends on the SFR and the half light radius: Galaxies with higher SFR and larger half light radii show lower metallicities at a given stellar mass. One possible scenario for the trends is the infall of pristine gas accreted from IGM or through merger events. Our data points show larger scatter than the fundamental metallicity relation (FMR) at z~0.1 and the average metallicities slightly deviate from the FMR. The compilation of the mass-metallicity relations at z~3 to z~0.1 shows that they evolve smoothly from z~3 to z~0 without changing the shape so much except for the massive part at z~0.

description: Sustainable intensification promotes environmentally sound and productive agriculture. However, use of sustainable intensification practices (SIPs) is low in many sub-Sharan African countries. This study examined the adoption of SIPs in Kenyan rural and peri-urban vegetable production to understand the scale of and underlying factors in the use of SIPs. A multistage sampling technique was employed to randomly select 685 rural and peri-urban vegetable farm households. Household data was then collected and anaylsed for four practices namely improved irrigation, integrated soil fertility, organic manure and crop diversification using a pre-tested structured questionnaire. A multivariate probit model was run to model simultaneous interdependent adoption decisions. Adoption of organic manure and African indigenous vegetables (AIV) diversification was high in both rural and peri-urban areas. However, adoption of improved irrigation systems and integrated soil fertility management was low, and even significantly lower in rural areas than in peri-urban areas (p < 0.041). Similarly, adoption intensity of SIPs was lower in rural areas than in peri-urban areas. Furthermore, the findings also show complementarities and substitutabilities between SIPs. Market integration, the farm location and household income were the major factors heavily influencing the adoption of most SIPs. Policies and programmes that seek to build household financial capital base and integrate farm households into effective and efficient vegetable markets need to be formulated and implemented in order to enhance adoption of SIPs in AIV production.

Has ecocriticism gone off the deep end? Rethinking ecological formalism and social ecology
Creators: name: Green, John
Publisher: name: University of British Columbia
Year: 2009

description: Ecocriticism, with its dual interests in the study of nature and the protection of the environment, seems as though it should be a discipline that flourishes in a liberal academy that is comfortable with theory. It is not. This project looks at the dominant ideology that structures much ecocritical writing, deep ecology, and it suggests that the seemingly radical environmental politics that it proposes are really articulations of traditional anti-theoretical conservatism. In the first chapter, I look at The Ecocriticism Reader (1996), as a watershed publication in the rise of the new discipline, a publication that, at its foundation, deploys deep ecology as a given, even attempting to bring it in line with theory. The following chapter employs varying techniques to show how deep ecology functions on ideological grounds that are flawed, criticism levied from philosophy and science; central to that chapter is a parallel that I draw between deep ecology as a type of ecological formalism and the literary formalism of the New Critics and the Russian Formalists. The final chapter suggests a new direction that ecocriticism can take after the dismissal of deep ecology; social ecology, unlike deep ecology, is not anathema to theory, and by rehabilitating culture from its position on the bottom of deep ecology’s hierarchy, social ecology can offer new ways to think about the discipline.

description: In this paper, a cellular automaton model of vehicular traffic in Manhattan-like urban system is proposed. In this model, the origin-destination trips and traffic lights have been considered. The system exhibits three different states, i.e., moving state, saturation state and global deadlock state. With a grid coarsening method, vehicle distribution in the moving state and the saturation state has been studied. Interesting structures (e.g., windmill-like one, T-shirt-like one, Y-like one) have been revealed. A metastability of the system is observed in the transition from saturation state to global deadlock state. The effect of advanced traveller information system (ATIS), the traffic light period, and the traffic light switch strategy have also been investigated.

description: This study analyzes use of the terms ‘engaged scholarship’ and ‘engaged research’ in all 11 NCA journals to develop a grounded practical theory (GPT) of engaged communication research. We find that the practice of engaged scholarship is defined by tensions between role identity goals of scholar and practitioner; relational goals of expertise and partnership; and outcome goals of theory and practice. To manage these tensions, engaged scholars (1) discursively construct themselves in dual roles of academic-community member; (2) advocate for researcher reflexivity to manage power dynamics; and (3) privilege theory-practice integrative outcomes. Underlying these tactics, engaged scholars intimate moral and strategic arguments for the practice of engaged scholarship. We discuss the implications of these situated ideals for assessing ‘what counts’ as good scholarship among researchers working at the intersections of theory and practice.

description: Individuals’ information seeking and the role of emotions are important to crisis communication research. A survey was conducted (N = 1100) to examine the chain effects of crisis factors on college young adults’ discrete emotions and perceived channel significance. Key findings suggest that crisis factors affect channel significance both directly and indirectly. Crisis factors overall elicit more fear and anxiety (attribution-independent emotions) than anger and sympathy (attribution-dependent emotions). Uncertainty does not affect perceived channel significance, while urgency prompts individuals to seek out non-traditional media and severity affects information seeking on all channels. Attribution-independent emotions such as fear and sadness have positive mediating effects, and attribution-dependent emotions such as anger and sympathy have negative mediating effects. Finally, media richness per se may not be a prominent concern during emergencies.

description: The 31S(p,γ)32Cl reaction is expected to provide the dominant break-out path from the SiP cycle in novae and is important for understanding enrichments of sulfur observed in some nova ejecta. We studied the 32S(3He,t)32Cl charge-exchange reaction to determine properties of proton-unbound levels in 32Cl that have previously contributed significant uncertainties to the 31S(p,γ)32Cl reaction rate. Measured triton magnetic rigidities were used to determine excitation energies in 32Cl. Proton-branching ratios were obtained by detecting decay protons from unbound 32Cl states in coincidence with tritons. An improved 31S(p,γ)32Cl reaction rate was calculated including robust statistical and systematic uncertainties.

description: Nur selten verlaufen Operationen der humanitären Hilfe gradlinig. Oftmals werden Hilfsaktionen durch Unterbrechungen, wie zum Beispiel Nachbeben, Epidemien oder Brände gestört. Auf diese Unterbrechungen muss dann reagiert werden, während die laufende Hilfsaktion fortgesetzt wird. Diese Situationen werden Overlapping Disaster genannt. Da eine Optimierung der Hilfsgüterallokation in der akuten Situation zu zeitaufwendig wäre, werden in dieser Arbeit Szenarien generiert und vorab mit einem multikriteriellen gemischt-ganzzahligen Transshipmentmodell gelöst. Es werden zwei verschiedene Lösungsmethoden entwickelt, die Unsicherheiten in Bezug auf die Entwicklung der Situation berücksichtigen. Die Ergebnisse der Szenarien werden daraufhin analysiert und es werden verschiedene Indikatoren zur Evaluation der Handlungsalternativen definiert. Basierend auf den Ausprägungen der Indikatoren werden die verschiedenen Lösungen bewertet und es werden Handlungsempfehlungen formuliert, die den Entscheidungsträger vor Ort bei der Allokation der Hilfsgüter unterstützen.
description: Humanitarian relief operations rarely proceed smoothly and disruptions as, e.g., the outbreak of an epidemic or aftershocks, are common. Such situations are known as overlapping disasters. Relief organizations have to deal with the disruptions while at the same time the ongoing relief operation has to proceed. As future developments are uncertain, the aim cannot be to determine a unique optimal solution. Rather, various scenarios are formulated, representing possible developments of the situation. A multi-objective transshipment model is formulated to find efficient allocations of relief items for different scenarios. The model mHumLog is solved by two solution methods both considering uncertainties about future developments. Different indicators are developed for evaluating the scenarios in order to find appropriate decision rules to support the aid worker in allocating relief items.
Protection of zinc against etoposide-induced hematopoietic toxicity
Creators: name: Purtzki, Markus J.
Publisher: name: University of British Columbia
Year: 2009

description: Metallothionein (MT) is a low-molecular weight protein with many physiological functions, including contributing to zinc homeostasis and serving as an antioxidant. MT can reduce the efficacy of chemotherapy drugs by inducing drug resistance in cancerous cells. On the other hand, it can also offer protection to normal cells against side effects of cancer treatment (i.e. radiation therapy). Clearly, optimum levels of MT in a tissue-specific manner are important for to the ultimate positive outcomes of cancer treatment. Zinc is a potent inducer of MT in a various tissues (i.e. peripheral blood cells) and has been linked to resistance to chemotherapy drugs. However, it presently is not known whether zinc supplementation influences the resistance of breast cancer cells to chemotherapy drugs and offers protection to normal cells from chemotherapy drug-induced cytotoxicity. Human blood mononuclear THP-1 cells and breast cancer MBA-MB-231 cells were cultured in DMEM for 3 days followed by zinc supplementation using zinc sulfite at 0, 25, 50 or 100 μM for 24 hrs. Zinc supplementation resulted in a dose-dependent increase in total cellular zinc concentration and the abundance of the labile intracellular pool of zinc in THP-1 cells, but not in MDA-MB-231 cells. Similarly, zinc supplementation at 50 and 100 μM also significantly increased the abundance of MT1x and MT2a mRNA in THP-1 cells, while zinc supplementation at 100 μM increased the abundance of MT3a mRNA. In contrast, the abundance of MT1x, MT2a and MT3a mRNAs was not affected by zinc supplementations in MDA-MB-231. When THP-1 cells were exposed to 2μM etoposide, a chemotherapy drug, for 24 hrs, zinc supplementation at 50 and 100 μM reduced etoposide-induced apoptosis by 15 and 33%, respectively with an inverse correlation between zinc supplementation and etoposide-induced apoptosis (r² = 0.99). Furthermore, zinc supplementation also significantly reduced caspase-3 and -9 activities and etoposide-induced DNA oxidative damage. The antioxidant properties of MT likely reduced the oxidative stress of etoposide resulting in the inhibition of apoptosis. Overall, these results suggested that zinc plays a potentially pivotal role in against chemotherapy (i.e. etoposide)-induced cytotoxicity in normal cells.

description: The eigenvalues and eigenfunctions of a linear α^{2}-dynamo have been computed for different spatial distributions of an isotropic α-effect. Oscillatory solutions are obtained when αexhibits a sign change in the radial direction. The time-dependent solutions arise at so called exceptional points where two stationary modes merge and continue as an oscillatory eigenfunction with conjugate complex eigenvalues. The close proximity of oscillatory and non-oscillatory solutions may serve as the basic ingredient for reversal models that describe abrupt polarity switches of a dipole induced by noise. Whereas the presence of an inner core with different magnetic diffusivity has remarkable little impact on the character of the dominating dynamo eigenmodes, the introduction of equatorial symmetry breaking considerably changes the geometric character of the solutions. Around the dynamo threshold the leading modes correspond to hemispherical dynamos even when the symmetry breaking is small. This behavior can be explained by the approximate dipole-quadrupole degeneration for the unperturbed problem. More complicated scenarios may occur in case of more realistic anisotropies of α- and β-effect or through non-linearities caused by the back-reaction of the magnetic field (magnetic quenching).

description: We report on the formation of ultracold fermionic Feshbach molecules of $^{23}$Na$^{40}$K, the first fermionic molecule that is chemically stable in its ground state. The lifetime of the nearly degenerate molecular gas exceeds 100 ms in the vicinity of the Feshbach resonance. The measured dependence of the molecular binding energy on the magnetic field demonstrates the open-channel character of the molecules over a wide field range and implies significant singlet admixture. This will enable efficient transfer into the singlet vibrational ground state, resulting in a stable molecular Fermi gas with strong dipolar interactions.

description: Ausgehend von Anwendungsproblemen des Werkzeugs „Modellierung und Simulation“ wird eine praxisnahe Vorgehensweise abgeleitet, die simulationsbasierte Vergleichsstudien unter den Aspekten Nachvollziehbarkeit, Vergleichbarkeit und Realitätsnähe erlaubt. Diese wird am Beispiel der Entwicklungsoptionen der Großkraftwerkstechnik hinsichtlich Wirkungsgradsteigerung und CO2-Emissionsminderung genutzt. Betrachtet werden stein- und braunkohlebefeuerte Dampfkraftwerke nach dem Stand der Technik, deren möglichen Fortentwicklung durch gesteigerte Dampfparameter, Braunkohlevortrocknung sowie CO2-Abtrennung im Post-Combustion- und Oxyfuel-Verfahren. Zudem werden die Unterschiede verschiedener Gasturbinenmodelle bei erdgasbefeuerten GuD-Kraftwerken untersucht.
description: A methodology with a practical orientation is derived from experienced issues in the application of modelling and simulation. This methodology allows the simulation based comparative studies in terms of their replicability, comparability and modelling close to reality. It is used to investigate development options of utility sized power plants with regard to efficiency improvements and/or CO2 emission reductions. The study compares current state of the art hard coal fired and lignite fired steam power plants and their improvements by increasing steam parameters, lignite pre-dying as well as the application of CO2 capture by post combustion or oxyfuel technology. Furthermore, the impact of using different gas turbine models for natural gas fired combined cycle power plants are studied.

description: We discuss the accurate determination of matrix elements < f| h_w | i > where neither |i> nor |f> is the vacuum state and h_w is some operator. Using solutions of the Generalized Eigenvalue Problem (GEVP) we construct estimators for matrix elements which converge rapidly as a function of the Euclidean time separations involved. |i> and |f> may be either the ground state in a given hadron channel or an excited state. Apart from a model calculation, the estimators are demonstrated to work well for the computation of the B*B pi-coupling in the quenched approximation. They are also compared to a standard ratio as well as to the "summed ratio method" of [1,2,3]. In the model, we also illustrate the ordinary use of the GEVP for energy levels.

Crossed Andreev reflection and spin-resolved non-local electron transport

description: The phenomenon of crossed Andreev reflection (CAR) is known to play a key role in non-local electron transport across three-terminal normal-superconducting-normal (NSN) devices. Here we review our general theory of non-local charge transport in three-terminal disordered ferromagnet-superconductor-ferromagnet (FSF) structures. We demonstrate that CAR is highly sensitive to electron spins and yields a rich variety of properties of non-local conductance which we describe non-perturbatively at arbitrary voltages, temperature, degree of disorder, spin-dependent interface transmissions and their polarizations. We demonstrate that magnetic effects have different implications: While strong exchange field suppresses disorder-induced electron interference in ferromagnetic electrodes, spin-sensitive electron scattering at SF interfaces can drive the total non-local conductance negative at sufficiently low energies. At higher energies magnetic effects become less important and the non-local resistance behaves similarly to the non-magnetic case. Our results can be applied to multi-terminal hybrid structures with normal, ferromagnetic and half-metallic electrodes and can be directly tested in future experiments.

description: Gegenstand der Dissertation ist die Entwicklung und der Vergleich zweier numerischer Modelle zur Simulation der Manövrierbewegungen von Schiffen in Wellen. Das eine Modell basiert auf einem Zwei-Zeitskalen-Ansatz, welches die grundlegenden Bewegungsgleichungen in zwei Gruppen aufteilt – die nicht-frequente Manövrierbewegung und die höherfrequente, welleninduzierte Bewegung. Beide Gruppen werden einzeln gelöst und gewisse Parameter werden ausgetauscht. Das andere Modell beschreibt eine vereinheitlichte Theorie. Es basiert auf der Impulsantwortfunktion in welcher die Retardationsfunktionen für den gesamten Bereich an Bewegungsfrequenzen gebildet und während der Zeitsimulation über die Zeit integriert werden. Eine Validierung mit experimentellen Daten aus der Literatur wird für beide Methoden durchgeführt.
description: This thesis reports on the development and the subsequent comparison of two numerical models to simulate the maneuvering motion of ships in waves. A two-time scale model is introduced that divides the basic motion equations into two groups - the zero-frequency maneuvering motion and the high-frequency wave-induced motion. Each group is solved separately and certain parameters are exchanged. Additionally, a unified theory is presented. It is based on the impulse-response function, in which the retardation functions are built up for the entire motion frequency range and integrated during the time simulation over the elapsed time. A validation with experimental data from the literature is conducted with both methods.
Origin of crack pattern in the deposition from drying colloidal suspension

description: The fracture mechanics was widely employed to explain the crack propagation in the deposition produced by drying colloidal suspension. However, more complex than conventional fracture, those cracks periodically distribute and make up a unique pattern. This still remains mysterious so far. Inspired by the concept of spinodal decomposition, here, we develop the theory to elucidate the spatial arrangement of the cracks, which indicates that the crack pattern is generated by the phase separation of colloidal clusters and water. It concludes that the crack spacing results from the wavelength of the concentration fluctuation during the phase separation, linearly growing with the increase of the deposition thickness and initial particle concentration, which is consistent with experimental results.
