description: The Leading Arm is a tidal feature that is in front of the Magellanic Clouds on their orbit through the Galaxy's halo. Many physical properties of the Leading Arm, such as its mass and size, are poorly constrained because it has few distance measurements. While H$α$ measurements have been used to estimate the distances to halo clouds, many studies have been unsuccessful in detecting H$α$ from the Leading Arm. In this study, we explore a group of H I clouds which lie $75^{\circ} - 90^{\circ}$ from the Magellanic Clouds. Through ultraviolet and 21-cm radio spectroscopy, this region, dubbed the Leading Arm Extension, was found to have chemical and kinematic similarities to the Leading Arm. Using the Wisconsin H$α$ Mapper, we detect H$α$ emission in four out of seven of our targets. Assuming that this region is predominantly photoionized, we use a radiation model that incorporates the contributions of the Galaxy, Magellanic Clouds, and the extragalactic background at $\rm z = 0$ to derive a heliocentric distance of $d_{\odot}\ge13.4~kpc$. We also use this model to rederive H$α$ distances of $d_{\odot} \geq 5.0$ kpc and $d_{\odot} \geq 22.9~kpc$ to two clouds in the literature that might also be associated with the Leading Arm. Using these new measurements, and others in the literature, we provide a general trend of the variation of Leading Arm heliocentric distance as a function of Magellanic Stream longitude, and explore its implications for the origin and closest point of approach of the Leading Arm.

Leadership and educational technologies : leading the charge for e-learning in British Columbia schools
Creators: name: LaBonte, Randy
Publisher: name: University of British Columbia
Year: 2009

description: Leadership and change have been well studied, yet little has been written specifically on the role leaders play in the success or failure of implementing educational technologies and adopting e-learning programs. Traditional views of leadership emphasize charisma and personal conviction while recent studies focus on relationships within community and a leader's ability to cope with complex change. After the Ministry of Education lifted an enrolment cap on British Columbia (BC) K-12 distance education programs in 2002, the number of e-learning programs quadrupled between 2002 and 2004 and provided an excellent opportunity to examine how three dimensions - leadership, pedagogy and technology - interacted, and how leadership influenced change. The purpose of the study was to examine how leadership practice influenced use of educational technologies to improve learning. A case study of leadership within the new BC Ed Online organization was conducted. The emergence of BC Ed Online provided an exceptional opportunity to study leaders within BC's e-learning community. The study found that government policy could precipitate education change and reform, and that many leaders in this community viewed educational technologies as catalysts to educational reform. Leadership practice within this community exhibited features of transformational leadership, and tension between top down and bottom up approaches could be attributed to lack of resources to support leaders. The study also reaffirmed the key role leadership plays in systemic change and confirmed that without a clear vision, collaborative leadership, and a systems approach, organizations could commit precious resources to e-learning without much success. The study served to enlighten several issues in both theory and practice regarding leadership and implementation of educational technologies: individual perspectives within complex adaptive systems will vary depending on position and the role of individuals; emotional investment is attributed to leadership practice, yet little is written about how that emotional commitment is invested into new and emerging organizations; resolving tensions created through interactions between individuals and organizations within complex adaptive systems requires meaningful dialogue within a community that engages constituents; and, finally, transformative leadership theory may be useful in further examination of leadership as it pertains to implementation of educational technologies.

description: Emergence of crisis in financial markets, especially banks, have forced a change in approach to risk management. It has become necessary to develop new or refine existing models of early bankruptcy threat warning, as well as establishing the potential impact of bank failures. One of the tools, indicating that resistance to the phenomenon of crisis is “stress testing”. Its aim, at least in the case of banks, is concerned with estimating the level of economic resistance towards the occurring risk. Some of these risks are: the non-payment of loans due to deterioration in the economic situation of a country, fluctuations in interest rates, exchange rates and a fall in prices of securities which are traded on stock exchanges. This article discusses the nature of stress testing and shows the current legislation in Poland and presents the results of a stress testing conducted on the largest U.S. banks in May 2009. The rank and results of these studies show the importance of the role of stress testing as a complementary research of a diagnostic and prognostic nature.

description: In order to show the effect of direct foreign investment flows on the economy of Jordan, this study comes to examine the economic and financial risks on FDI on the macro level over the period (1997- 2007). This study applies a version of the model developed by Chan and Gemayel (2004) by using Multiple Linear Regression Model. The analysis revealed that there exists significant and positive relationship between foreign direct investment flows into the economy of Jordan and economic and financial variables. The study claims for further FDI promotion through incentives to attract new investments. These factors are: providing targeted fiscal incentives, such as tax concessions, cash grants, and specific subsidies; improving domestic infrastructure; promoting local skills development to meet investor needs and expectations; establishing broad-reaching FDI promotion agencies and improving the regulatory environment and decreasing red tape.

The treatment of zero eigenvalues of the matrix governing the equations of motion in many-body Green's function theory

Publisher: name: arXiv
Year: 2004
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: The spectral theorem of many-body Green's function theory relates thermodynamic correlations to Green's functions. More often than not, the matrix governing the equations of motion has zero eigenvalues. In this case, the standard text-book approach requires both commutator and anti-commutator Green's functions to obtain equations for that part of the correlation which does not lie in the null space of the matrix. In this paper, we show that this procedure fails if the projector onto the null space is dependent on the momentum vector. We propose an alternative formulation of the theory in terms of the non-null space alone and we show that a solution is possible if one can find a momentum-independent projector onto some subspace of the non-null space. To do this, we enlist the aid of the singular value decomposition (SVD) of the equation of motion matrix in order to project out the null space, thus reducing the size of the matrix and eliminating the need for the anti-commutator Green's function. We extend our previous work, dealing with a ferromagnetic Heisenberg monolayer and a momentum-independent projector onto the null space, where both multilayer films and a momentum-dependent projector are considered. We develop the numerical methods capable of handling these cases and offer a computational algorithmus that should be applicable to any similar problem arising in Green's function theory.

description: We present a global agricultural greenhouse gas model that assesses emissions from land-use change. In addition to evaluating shifts in and out of crop production, we develop a pasture model to assess extensification and intensification of global livestock production based on herd size and stocking rate. We apply the model to a scenario that introduces a tax on me-thane emissions from cattle in the United States. The resulting expansion of pasture in the rest of the world leads to substantially higher emissions than without the tax. The yearly average emissions from the tax are 260 metric tons of CO2-equivalent.

Here, we study a class of candidate molecular ions for DPQL, the cationic alkaline-earth monoxides and monosulfides, which possess suitable structure for DPQL and can be produced in existing atomic ion experiments with little additional complexity. We present calculations of DPQL operations for one of these molecules, CaO$^+$, and discuss progress towards experimental realization. We also further develop the theory of DPQL to include state preparation and measurement and entanglement of multiple molecular ions.

description: It is argued that if cosmic rays penetrate into molecular clouds, the total energy they lose can exceed the energy from galactic supernovae shocks. It is shown that most likely galactic cosmic rays interacting with the surface layers of molecular clouds are efficiently reflected and do not penetrate into the cloud interior. Low-energy cosmic rays ($E<1$ GeV) that provide the primary ionization of the molecular cloud gas can be generated inside such clouds by multiple shocks arising due to supersonic turbulence.

description: The mainstream economy poses the opinion that a competitive advantage lies in resources, and, consequently - in competences as well - being a share of a single company and remaining under its sole control. Recently, some researchers (e.g. Castaldo, 2007; Lavie, 2006) have revised that approach and tend to emphasise the role of other sources of competitive advantage in business strategy, which embrace new, intangible assets. Such assets are being born and developed only within the inter-firm relationships built in network environment. Thus, the presented paper focuses on relational-based approach towards gaining relational rent. It aims at discussing the sources of an appropriated relational rent and, presenting - after Lavie, a new types of rent extracted from alliance networks. Next, the author presents some empirical evidence from healthcare market in Poland. Inter-organizational relations represent the central level of analysis of the achievement of relational competitive advantage. Empirical results indicate the crucial role of trust and commitment in the market relationships. They are the key success factors which enable the service providers to build a differentiated market position. The researched organizations pose effective communication between the parties of the relationship and the satisfaction resulting from the mutual respect and recognition as the components of value offerings.

description: We have developed a technology to reproducibly make gaps with distance control on the single atom scale. The gold contacts are flat on the nanometre scale and are fabricated on an oxidized aluminium film that serves as a gate. We show that these contacts are clean and can be stabilized via chemical functionalization. Deposition of conjugated molecules leads to an increase in the gap conductance of several orders of magnitude. Stable current-voltage characteristics at room temperature are slightly nonlinear. At low temperature, they are highly nonlinear and show a clear gate effect.

description: In this paper, we define the notion of a virtually symmetric representation of representations of virtual braid groups and prove that many known representations are equivalent to virtually symmetric. Using one such representation, we define the notion of virtual link groups which is an extension of virtual link groups defined by Kauffman. Moreover, we introduce the concept of marked Gauss diagrams as a generalisation of Gauss diagrams and their interpretation in terms of knot-like diagrams. We extend the definition of virtual link groups to marked Gauss diagrams and define their peripheral structure. We define $C_m$-groups and prove that every group presented by a $1$-irreducible $C_1$-presentation of deficiency $1$ or $2$ can be realized as the group of a marked Gauss diagram.

description: We develop a fourth order accurate finite difference method for the three dimensional elastic wave equation in isotropic media with the piecewise smooth material property. In our model, the material property can be discontinuous at curved interfaces. The governing equations are discretized in second order form on curvilinear meshes by using a fourth order finite difference operator satisfying a summation-by-parts property. The method is energy stable and high order accurate. The highlight is that mesh sizes can be chosen according to the velocity structure of the material so that computational efficiency is improved. At the mesh refinement interfaces with hanging nodes, physical interface conditions are imposed by using ghost points and interpolation. With a fourth order predictor-corrector time integrator, the fully discrete scheme is energy conserving. Numerical experiments are presented to verify the fourth order convergence rate and the energy conserving property.

description: We present new recursion relations for tree amplitudes in gauge theory that give very compact formulas. Our relations give any tree amplitude as a sum over terms constructed from products of two amplitudes of fewer particles multiplied by a Feynman propagator. The two amplitudes in each term are physical, in the sense that all particles are on-shell and momentum conservation is preserved. This is striking, since it is just like adding certain factorization limits of the original amplitude to build up the full answer. As examples, we recompute all known tree-level amplitudes of up to seven gluons and show that our recursion relations naturally give their most compact forms. We give a new result for an eight-gluon amplitude, A(1+,2-,3+,4-,5+,6-,7+,8-). We show how to build any amplitude in terms of three-gluon amplitudes only.

The political-economy of tax reforms in Pakistan: the ongoing saga of the GST

description: Should tax reforms be guided by rules of thumb suggested by the IMF, or directions or reform based on analytical approaches, such as optimal tax theory? In many cases, the applications of the directions of reform—which suggest a differentiation of the structure given distributional, incentive and revenue concerns, can be brought close to the IMF prescriptions by a judicious balancing of tax instruments—such as a single or dual rate VAT together with systems of excises. But in some cases, such as Pakistan, neither prescription has yielded either the revenues anticipated, nor the necessary salutary effect on incentives for production—despite repeated attempts during successive IMF programs over 20 years. The proposition in this paper is that the collusion between vested interests, including the tax administration has led to the difficulties that have also exacerbated the “trust deficit” between the federation and the provinces. In this paper we examine issues of collusion between the tax administration and vested interests, and also difficulties arising from assigning a very mobile base to a level of government that does not have the technical capability to administer it. Section I examines method, based on the theory of reform. Section II posits the antecedents of tax reform in Pakistan over the past 50 years. Section III focuses on the design and implementation of the GST. Section IV examines the political economy of provincial revenue assignments; and Section V concludes.
Educating lawyers : how law graduates perceive first year law school educational practices
Creators: name: Fitzgerald, Maureen Fay
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to better understand the educational practices used in first year law school and the impact of these practices on students. Prior research showed that students are negatively impacted during first year and that educational practices are somewhat to blame. This study is consistent with this literature and provides new and important information about the extent to which teaching methods; content and curriculum; assessment and grading; learning theory and aims of law school all contribute to the experiences of law students. The research method in this study consisted of in-depth interviews of 19 University of British Columbia law school graduates who had completed law school a few months earlier. Graduates were questioned about their perceptions of both the first year law school educational practices and their impacts, specifically in relation to the five core courses taught in first year law school. This study revealed that students found first year law school problematic in many ways. This research supports the literature that suggests the case method and the lecture method used in first year are not entirely effective or efficient for student learning. The case method seems to makes learning more difficult and slower than it needs to be. As suggested in the literature the lecture method was useful in providing information to students and this information helped students focus their studies. However, these typically didactic lectures did not appear to engage students or encourage deeper learning. The question and answer technique used in some lectures intimidated students and appeared to interfere with their learning.
Acoustic propulsion of a small bottom-heavy sphere

description: We present here a comprehensive derivation for the speed of a small bottom-heavy sphere forced by a transverse acoustic field and thereby establish how density inhomogeneities may play a critical role in acoustic propulsion. The sphere is trapped at the pressure node of a standing wave whose wavelength is much larger than the sphere diameter. Due to its inhomogeneous density, the sphere oscillates in translation and rotation relative to the surrounding fluid. The perturbative flows induced by the sphere's rotation and translation are shown to generate a rectified inertial flow responsible for a net mean force on the sphere that is able to propel the particle within the zero-pressure plane. To avoid an explicit derivation of the streaming flow, the propulsion speed is computed exactly using a suitable version of the Lorentz reciprocal theorem. The propulsion speed is shown to scale as the inverse of the viscosity, the cube of the amplitude of the acoustic field and is a non trivial function of the acoustic frequency. Interestingly, for some combinations of the constitutive parameters (fluid to solid density ratio, moment of inertia and centroid to center of mass distance), the direction of propulsion is reversed as soon as the frequency of the forcing acoustic field becomes larger than a certain threshold. The results produced by the model are compatible with both the observed phenomenology and the orders of magnitude of the measured velocities.

description: This study tests the null hypothesis that it is sufficient to interview only the household head to obtain accurate information on household income. Results show that using a husband’s estimate of his wife’s income does not produce statistically reliable results for poverty analysis. Estimates of the wife’s income provided by the husband and wife are in agreement in only six percent of households. While limiting interviews to one person has the advantage of reducing the time and expense of household surveys, this appears detrimental in terms of accuracy, and may lead to incorrect conclusions on the determinants of poverty.

description: Considering the impact of recommendations on item providers is one of the duties of multi-sided recommender systems. Item providers are key stakeholders in online platforms, and their earnings and plans are influenced by the exposure their items receive in recommended lists. Prior work showed that certain minority groups of providers, characterized by a common sensitive attribute (e.g., gender or race), are being disproportionately affected by indirect and unintentional discrimination. Our study in this paper handles a situation where ($i$) the same provider is associated with multiple items of a list suggested to a user, ($ii$) an item is created by more than one provider jointly, and ($iii$) predicted user-item relevance scores are biasedly estimated for items of provider groups. Under this scenario, we assess disparities in relevance, visibility, and exposure, by simulating diverse representations of the minority group in the catalog and the interactions. Based on emerged unfair outcomes, we devise a treatment that combines observation upsampling and loss regularization, while learning user-item relevance scores. Experiments on real-world data demonstrate that our treatment leads to lower disparate relevance. The resulting recommended lists show fairer visibility and exposure, higher minority item coverage, and negligible loss in recommendation utility.

description: Single crystals of the filled-skutterudite compound NdOs$_4$Sb$_{12}$ have been investigated by means of electrical resistivity, magnetization, and specific heat measurements. The NdOs$_4$Sb$_{12}$ crystals have the LaFe$_4$P$_{12}$-type cubic structure with a lattice parameter of 9.3 Å. Possible heavy-fermion behavior is inferred from specific heat measurements, which reveal a large electronic specific heat coefficient $γ\approx 520$ mJ/mol-K$^2$, corresponding to an effective mass $m^* \sim$ 98 $m_e$. Features related to a ferromagnetic transition at {$\sim$ 0.9 K} can be observed in electrical resistivity, magnetization and specific heat. Conventional Arrott-plot analysis indicates that NdOs$_4$Sb$_{12}$ conforms to mean-field ferromagnetism.

Fast magnetization switching of Stoner particles: A nonlinear dynamics picture

description: The magnetization reversal of Stoner particles is investigated from the point of view of nonlinear dynamics within the Landau-Lifshitz-Gilbert formulation. The following results are obtained. 1) We clarify that the so-called Stoner-Wohlfarth (SW) limit becomes exact when damping constant is infinitely large. Under the limit, the magnetization moves along the steepest energy descent path. The minimal switching field is the one at which there is only one stable fixed point in the system. 2) For a given magnetic anisotropy, there is a critical value for the damping constant, above which the minimal switching field is the same as that of the SW-limit. 3) We illustrate how fixed points and their basins change under a field along different directions. This change explains well why a non-parallel field gives a smaller minimal switching field and a short switching time. 4) The field of a ballistic magnetization reversal should be along certain direction window in the presence of energy dissipation. The width of the window depends on both of the damping constant and the magnetic anisotropy. The upper and lower bounds of the direction window increase with the damping constant. The window width oscillates with the damping constant for a given magnetic anisotropy. It is zero for both zero and infinite damping. Thus, the perpendicular field configuration widely employed in the current experiments is not the best one since the damping constant in a real system is far from zero.

Solar slow magneto-acoustic-gravity waves: an erratum correction and a revisited scenario

description: Slow waves are commonly observed on the entire solar atmosphere. Assuming a thin flux tube approximation, the cut-off periods of slow-mode magneto-acoustic-gravity waves that travel from the photosphere to the corona were obtained in Costa et al. (2018). In that paper, however, a typo in the specific heat coefficient at constant pressure $c_{\mathrm{p}}$ value led to an inconsistency in the cut-off calculation, which is only significant at the transition region. Due to the abrupt temperature change in the region, a change of the mean atomic weight (by a factor of approximately two) also occurs, but is often overlooked in analytical models for simplicity purposes. In this paper, we revisit the calculation of the cut-off periods of magneto-acoustic-gravity waves in Costa et al. (2018) by considering an atmosphere in hydrostatic equilibrium with a temperature profile, with the inclusion of the variation of the mean atomic weight and the correction of the inconsistency aforementioned. In addition, we show that the cut-off periods obtained analytically are consistent with the corresponding periods measured in observations of a particular active region.

Women of colour talk back : towards a critical race feminist practice of service-learning
Creators: name: Verjee, Begum
Publisher: name: University of British Columbia
Year: 2009

description: The University of British Columbia (UBC) is exploring ways in which to develop and implement service-learning. This study explores the development of service-learning from a critical race feminist perspective. Service-earning is a form of experiential education. It is a strategy or pedagogy where students learn and develop through service experiences which are designed to meet identified community issues, and are collaboratively organized between academic institutions and communities. Critical race feminism, as an epistemology, sets out to understand how society organizes itself along intersections of race, gender, class and all forms of social hierarchies. Critical race feminist theory utilizes counter-storytelling to legitimize the voices and experiences of women of colour, drawing on these knowledges toward the larger goal of eradicating all forms of social oppression. The central question for this study is this: how can UBC develop partnerships with individuals and communities of colour that would support and enhance the well-being of such communities, in a service-learning context, when the institution remains a site of white, male and class-based structures, discourses and practices? Through counter-storytelling, women of colour students, staff, faculty and non-university community members relay their perceptions and experiences at and with UBC. Their perceptions and experiences of systemic exclusion form the basis for the development of a service-learning model from a critical race feminist perspective in this thesis. The implementation of such a model would foster the development of respectful and mutually beneficial partnerships with individuals and communities of colour. This model calls for institutional accountability through institutional transformation from within, through the development of a Centre for Anti-Oppression Education, Training and Development, and the simultaneous creation of an Office for Critical Community Service-Learning outside the Point Grey campus. According to this study, such development must be founded on critical race feminist principles of education for transformative citizenship. These critical race feminist principles would encourage a transformative project for education through an emphasis on the development of respectful relationships across social hierarchies, and a commitment to co-creating and sustaining just communities in search for a more humane and equitable world.

description: Taking Lingtong Grand Canyon in Jingxi County, Baise City, Guangxi, China as a research object, the face-to-face questionnaire survey on tourist is carried out, in order to obtain the basic situation of the interviewees, as well as their expectation for the eco-tourism experience. Factor analysis method is adopted to test the interviewees’ expectation of the eco-tourism experience. Result shows that eco-tourism experience of tourist is mainly reflected in the ecological leisure experience, the ecological tourism experience, the ecological experience in scenic spot, and the self-realization experience. Analysis on the recognition of the expectation for eco-tourism experience shows that the interviewees’ expectations of the eco-tourism experience are in the order of the ecological experience in scenic spot, the eco-tourism experience, the ecological leisure experience, and the self-realization experience. Difference analysis on the interviewees’ expectations for the eco-tourism experience is carried out by market segmentation. Result shows that there are significant differences in the demand of eco-tourism experience among different types of tourisms. According to the investigation result, countermeasures for the construction and marketing of eco-tourism sites are put forward.

description: We consider joint probability distributions for the class of coupled Langevin equations introduced by Fogedby [H.C. Fogedby, Phys. Rev. E 50, 1657 (1994)]. We generalize well-known results for the single time probability distributions to the case of N-time joint probability distributions. It is shown that these probability distribution functions can be obtained by an integral transform from distributions of a Markovian process. The integral kernel obeys a partial differential equation with fractional time derivatives reflecting the non-Markovian character of the process.

description: We shall prove a convergence result relative to sequences of Minkowski symmetrals of general compact sets. In particular, we investigate the case when this process is induced by sequences of subspaces whose elements belong to a finite family, following the path marked by Klain in [13], and the generalizations in [4] and [2]. We prove an analogue result for Fiber symmetrization of a specific class of compact sets. The idempotency for symmetrization of this family of sets is investigated, leading to a simple generalization of a result from Klartag [14] regarding the approximation of a ball through a finite number of symmetrizations, and generalizing an approximation result in [9]
