description: Pixel lensing is the gravitational microlensing of light from unresolved stars contributing to the luminosity flux collected by a single pixel. A star must be sufficiently magnified, that is, the lens impact parameter must be less than a threshold value $u_T$ if the excess photon flux in a pixel is to be detected over the background. Assuming the parameters of the Isaac Newton Telescope and typical observing conditions, we present maps in the sky plane towards M31 of threshold impact parameter, optical depth, event number and event time scale, analyzing in particular how these quantities depend on $u_T$ in pixel lensing searches. We use an analytical approach consisting of averaging on $u_T$ and the star column density the optical depth, microlensing rate and event duration time scale. An overall decrease in the expected optical depth and event number with respect to the classical microlensing results is found, particularly towards the high luminosity M31 inner regions. As expected, pixel lensing events towards the inner region of M31 are mostly due to self-lensing, while in the outer region dark events dominate even for a 20% MACHO halo fraction. We also find a far-disk/near-disk asymmetry in the expected event number, smaller than that found by \cite{Kerins04}. Both for self and dark lensing events, the pixel lensing time scale we obtain is $\simeq 1 - 7$ days, dark events lasting roughly twice as long as self-lensing events. The shortest events are found to occur towards the M31 South Semisphere. We also note that the pixel lensing results depend on $$ and $$ values and ultimately on the observing conditions and telescope capabilities.

Putting values into practice : the role of moral and ethical values in planning a leadership training program
Creators: name: Gravelle, André H.
Publisher: name: University of British Columbia
Year: 2009

description: In program planning there is a wide variety of planning models, frameworks and philosophies that guide the actions of planners. This study was undertaken to observe how a certain perspective on program planning influenced the planning of an adult education program. The location for this study was the Meeting the Leadership Challenge (MLC) program, which is an executive education offering designed to teach leadership skills to mid to upper-level executives. This goal of this study was to observe what considerations guided instructors in the planning of the MLC program, and to determine to what degree these considerations reflected moral/ethical values in addition to or instead of pragmatic/instrumental values. The study involved an examination of a variety of planning considerations evident in the MLC program in order to see how certain types of values were reflected in each consideration. By undertaking . this study it was hoped that a greater understanding would be gained into what role values play in the planning process, and how understanding this better might help planners deal with the complex planning environment. This study is based on interviews with five instructors who were actively engaged in the ongoing planning of the MLC program. The findings that resulted from the interviews were categorized into planning considerations and were located on a values continuum that illustrated the extent to which each consideration was reflective of moral/ethical values or pragmatic/instrumental values. The study concluded that a wide range of values were evident in the planning considerations, and that the majority of considerations were reflective of both moral/ethical values as well as pragmatic/instrumental values. Understanding more about this distinction can help planners know when considerations that are reflective of certain values can be negotiated, and when they cannot. These discoveries support the belief about the complexity of the planning environment, and how learning more about the influence values have on the planning environment may enable planners to be more conscious and deliberate in their actions. In particular, it may enable planners to design programs in which their own actions more closely reflect, not only their own fundamental values and beliefs, but also those of their constituents.

description: Numerical results are presented for transport properties of two coupled double-level quantum dots. The results strongly suggest that under appropriate circumstances the dots can develop a novel ferromagnetic (FM) correlation at quarter-filling (one electron per dot). In the strong coupling regime (Coulomb repulsion larger than electron hopping) and with the inter-dot tunneling larger than the tunneling to the leads, an S=1 Kondo resonance develops in the density of states, leading to a peak in the conductance. A qualitative 'phase diagram', incorporating the new FM phase, is presented. It is also shown that the conditions necessary for the FM regime are less restrictive than naively believed, leading to its possible experimental observation in real quantum dots.

description: The properties which characterize the stationary Hall effect in a Hall bar are derived from the Langevin equations describing the Brownian motion of an ensemble of interacting moving charges in a constant externally applied electromagnetic field. It is demonstrated that a non-uniform current density a) superimposes on the injected one, b) is confined in a boundary layer located near the edges over the Debye-Fermi length scale c) results from the coupling between diffusion and conduction and d) arises because of charge accumulation at the edges. The theory can easily be transposed to describe the Hall effect in metals, semi-conductors and plasmas and agrees with standard and previously published results.

description: We propose an equation that describes M2-branes ending on M5-branes, and which generalizes the description of the D1-D3 system via Nahm's equation. The simplest solution to this equation constructs the transverse geometry in terms of a fuzzy three sphere. We show that the solution passes a number of consistency checks including a consistent reduction to the D1-D3 system, a calculation of the energy of the system, matching to the self-dual string solution in the M5-brane world volume, and a study of simple fluctuations about the ground state configuration. We write down certain terms in the effective action of multiple membranes, which includes a sextic scalar coupling.

description: Income inequality reflects resource allocations, and has important implications for public policy and institutional design. This paper investigates the factors determining inequality. This is especially relevant in Chile where income distribution has not improved in the past decades. We disaggregate income into different components, differentiating between urban and rural populations, and assesses the contributions of these sources to total income inequality, as measured by the Gini and generalized entropy inequality measures. Results indicate that important factor components explaining income distribution are education, type of occupation, and type of health system. In addition, the effects of these components differ significantly between urban and rural population

Nabbing the devil : practical considerations in the use of armed force in the apprehension and arrest of persons indicted for war crimes
Creators: name: Thomson, Gordon
Publisher: name: University of British Columbia
Year: 2009

description: This thesis considers the challenges faced by international criminal tribunals in gaining physical jurisdiction over those persons indicted for the commission of war crimes, crimes against humanity and genocide. The thesis covers the need for justice for victims of such crimes, the history of the laws of war, war crimes and their prosecution, the need for an interdiction instrument, the legal basis for acting with force to arrest indictees, the use of military force to effect such arrests, and some of the various political and practical issues that arise in such use of force. I sought out first hand quotes and stories contained in various media sources, books and court transcripts to lend a voice to the victims. Substantiating the requirement for justice, I researched the written works and oral texts of academics, politicians, jurists, and senior military commanders, who have experienced firsthand the difficulties in preventing atrocities and prosecuting accused. To concisely discuss the history of the laws of war, I studied various academic works on the conduct of war including the writings of various history, religious and legal academics, as well as several primary source documents, including religious texts. In considering current international tribunals, I relied on treaty and customary international law documents, United Nations' documentation, and the current tribunals' statutes. The case law on extraterritorial detention of accused was found in trial and appellate court decisions from the United States, United Kingdom, South Africa, Israel and the ICTY. The thesis concludes that current international tribunals lack necessary mechanisms for enforcing indictments and thus ensuring that accused are brought before the courts' jurisdiction. In light of this inadequacy, a practical mechanism is needed to effect the interdiction and arrest of indictees for current and future international criminal tribunals. In conclusion, the use of military force to secure the detention and delivery of accused before the jurisdiction of issuing courts can be justified and should be utilized when other options have failed to effect with celerity, the accused's arrest.

Using phase-referencing techniques we measure the relative separations of the systems to precisions of a few tens of micro-arcseconds. We present the first scientific results of these observations, including the astrometric detection of the faint third stellar component of the kappa Pegasi system.

description: Consumer behavior regarding two varieties of fresh peaches was studied in a socioeconomically middle-upper level minimarket. 106 two-phase surveys were conducted. The first part was done through a direct interview when the consumers purchased the fruit; the second when the fruit was consumed. The varietes used were the 'Royal Glory' peach and the 'African Gold' canning peach, chosen because they were so distinct. Descriptive aspects of consumption, sociodemographic traits and purchase attitudes were assessed using multivariate and univariate analyses. A demand characterized by preference to purchase in supermarkets was identified. 25% of all those surveyed were young and distinguished by their inexperience in acquiring fresh peaches. The point of sale was the factor which most determined purchase behavior, followed the variety of peach, with supermarkets and the "African Gold" variety being the most preferred. The willingness to pay for desired attributes had the lowest values.

description: We address the problem of planning robot motions in constrained configuration spaces where the constraints change throughout the motion. The problem is formulated as a fixed sequence of intersecting manifolds, which the robot needs to traverse in order to solve the task. We specify a class of sequential motion planning problems that fulfill a particular property of the change in the free configuration space when transitioning between manifolds. For this problem class, we develop the algorithm Planning on Sequenced Manifolds (PSM*) which searches for optimal intersection points between manifolds by using RRT* in an inner loop with a novel steering strategy. We provide a theoretical analysis regarding PSM*s probabilistic completeness and asymptotic optimality. Further, we evaluate its planning performance on multi-robot object transportation tasks.

description: We have measured soft x-ray photoemission and O 1{\it s} x-ray absorption spectra of Ca$_{1-x}$Sr$_x$RuO$_3$ thin films prepared {\it in situ}. The coherent and incoherent parts have been identified in the bulk component of the photoemission spectra, and spectral weight transfer from the coherent to the incoherent part has been observed with decreasing $x$, namely, with increasing orthorhombic distortion. We propose that, while the Ru 4d one-electron bandwidth does not change with $x$, the distortion and hence the splitting of the $t_{2\text{g}}$ band effectively increases electron correlation strength. Although strong mass enhancement is found in the electronic specific heat data, the coherent part remains wide, suggesting enhanced band narrowing only in the vicinity of {\it E$_{F}$}.

description: The paper aims to study the effects of reducing pesticide use by farmers in the arable sector in France and the feasibility of a policy target of reducing pesticide use by half. The originality of the approach is to combine statistical data and expert knowledge to describe low-input alternative techniques at the national level. These data are used in a mathematical programming model to simulate the effect on land use, production and farmers’ income of achieving different levels of pesticide reduction. The results show that reducing pesticide use by 30% could be possible without reducing farmers’ income. We also estimate the levels of tax on pesticides necessary to achieve different levels of reduction of pesticide use and the effect of an incentive mechanism combining a pesticide tax with subsidies for low-input techniques.

description: Although infrequent, sudden cardiac death (SCD) is a feared event in young and seemingly healthy athletes. Earlier studies reported an increased risk of SCD in endurance athletes with a relative risk of 2.5 when compared with non-athletes. Therefore, elite athletes often undergo cardiologic screening to identify potential risk factors associated with ventricular arrhythmia and SCD. The ideal screening protocol, however, has not yet been defined. The aim of this scoping review is to identify and synthesize all existing literature on valid diagnostic cardiac markers and phenotypes that are related with adverse outcome in athletes with ventricular arrhythmias and SCD, so they can serve as surrogate endpoints in sports cardiology studies and screening protocols.

description: Two-stage ensemble-based forecasting methods have been studied extensively in the wind power forecasting field. However, deep learning-based wind power forecasting studies have not investigated two aspects. In the first stage, different learning structures considering multiple inputs and multiple outputs have not been discussed. In the second stage, the model extrapolation issue has not been investigated. Therefore, we develop four deep neural networks for the first stage to learn data features considering the input-and-output structure. We then explore the model extrapolation issue in the second stage using different modeling methods. Considering the overfitting issue, we propose a new moving window-based algorithm using a validation set in the first stage to update the training data in both stages with two different moving window processes.Experiments were conducted at three wind farms, and the results demonstrate that the model with single input multiple output structure obtains better forecasting accuracy compared to existing models. In addition, the ridge regression method results in a better ensemble model that can further improve forecasting accuracy compared to existing machine learning methods. Finally, the proposed two-stage forecasting algorithm can generate more accurate and stable results than existing algorithms.

description: The aim of this paper is to set-up the algorithm for determining the degree of workability of the soil, to help the owners of family farms to plan working hours of agricultural machines, i.e. with the machine park management. The plans, which would be made by use of these algorithms and based on the accurate information of the cultivation conditions, would result in the appropriate use of time and capacity of the agricultural machines. In some sectors, such as agriculture or certain industries, chance that certain event occurs plays a very important role. The influence of random events, however, can be significantly reduced if decision makers are counting on them, reveal their nature and gather as much information about them as possible. Justification of new testing methods applied in the economy follows from the fact that, according to economic policy, the growing burden of risk that comes from the uncertainty is borne by farmers. The method that was used in the study is based on the Fuzzy mathematical modeling. Treating uncertain, vague and linguistically described phenomena and situations is facing difficulties in classical mathematics. In fact, a large degree of uncertainty is primarily resulting from uncertain external events. Fuzzy mathematical modeling can satisfactorily treat those parameters that are uncertain, vague and subjectively evaluated. The algorithm of risk assessment should be based on the opinion of economic experts, on the experience of the makers of planned decisions and on all the available data. Solving this problem can be approached in three ways: a) conventional method, b) applying the expert system, c) applying the theory of fuzzy sets. The main characteristic of the traditional way of solving the problem of evaluation is the almost exclusive reliance on measurable economic effects (time and money). Only in some rare cases, additional criteria are taken into account. Because of the importance of additional criteria, it is possible to develop a prototype of an expert system. Modeling problems in which the interdependence between the variables is very complex, fuzzy logic can be successfully applied. The complete review and analysis of the problem relying only on knowledge, experience of experts, without the fuzzy logic, would be impossible.
Re-representing authenticity through factory-printed cloths of Africa
Creators: name: Willard, Michelle
Publisher: name: University of British Columbia
Year: 2009

description: This paper examines the significance of factory-printed cloth in Africa and its potential to communicate various messages through its use as clothing. Factory-printed cloth also has unintended communicative value when it is displayed outside Africa in museum contexts. Factory-printed cloth made a relatively late appearance in the literature and exhibit history of African cloth. One reason for this is that the cloth was not considered 'African', as its production combines African design with European technology. The introduction of factory-printed cloth to Africa provided a new way in which to communicate messages through cloth, as faces of important people and text could be printed directly onto cloth. This technique has proved useful in commemorating special people or events in Africa. I begin this study by examining issues of authenticity, in relation to African material culture in museum settings and then provide a history of research carried out on African factory-printed cloth and its appearance in museum and gallery exhibitions. This has led to contemporary forms of art historical and anthropological research. Some of the latter, including my own, has involved field collecting of commemorative cloths in West Africa. My research resulted in a museum exhibition of factory-printed cloth at the University of British Columbia's Museum of Anthropology in February 2004. The Textile Museum of Canada also exhibited factoryprinted cloth in 2004. A case study of both these exhibits will take place here to illuminate how factory-printed cloth can provide insights into a post-colonial countries' political, social and cultural environments, whether the cloth is worn as clothing in Africa or displayed in museums abroad.

description: Context. Solar radio bursts originate mainly from high energy electrons accelerated in solar eruptions like solar flares, jets, and coronal mass ejections. A subcategory of solar radio bursts with short time duration may be used as a proxy to understand the wave generation and propagation within the corona. Aims. Complete case studies of the source size, position and kinematics of short term bursts are very rare due to instrumental limitations. A comprehensive multi-frequency spectroscopic and imaging study was carried out of a clear example of a solar type IIIb-III pair. Methods. In this work, the source of the radio burst was imaged with the interferometric mode, using the remote baselines of the LOw Frequency ARray (LOFAR). A detailed analysis of the fine structures in the spectrum and of the radio source motion with imaging was conducted. Results. The study shows how the fundamental and harmonic components have a significantly different source motion. The apparent source of the fundamental emission at 26.56MHz displaces away from the solar disk center at about 4 times the speed of light, while the apparent source of the harmonic emission at the same frequency shows a speed of < 0.02c. The source size of the harmonic emission, observed in this case, is smaller than that in previous studies, indicating the importance of the use of the remote baselines.

description: All-sky thermal and kinetic Sunyaev-Zel'dovich (SZ) maps are presented for assessing how well the PLANCK-mission can find and characterise clusters of galaxies, especially in the presence of primary anisotropies of the cosmic microwave background (CMB) and various galactic and ecliptic foregrounds. The maps have been constructed from numerical simulations of structure formation in a standard LCDM cosmology and contain all clusters out to redshifts of z = 1.46 with masses exceeding 5e13 M_solar/h. By construction, the maps properly account for the evolution of cosmic structure, the halo-halo correlation function, the evolving mass function, halo substructure and adiabatic gas physics. The velocities in the kinetic map correspond to the actual density environment at the cluster positions. We characterise the SZ-cluster sample by measuring the distribution of angular sizes, the integrated thermal and kinetic Comptonisations, the source counts in the three relevant PLANCK-channels, and give the angular power-spectra of the SZ-sky. While our results are broadly consistent with simple estimates based on scaling relations and spherically symmetric cluster models, some significant differences are seen which may affect the number of cluster detectable by PLANCK.

Based on a theoretical foundation, the calculation model was developed in order to assist short and long-term marketing decisions. The economical basis of the model is the combinative use of two market institutions: public warehousing and futures market. This electronically developed and working model ‘using excel background ‘allows all of the participants of the market: producers, consumers, banks and traders, to use this model in immediate calculations. In addition it helps in order to establish the own business strategy. The model can be used to analyze price influencing factors therefore; it can also be used for policy-making decisions for market participants as well as banks dealing with trade financing activity.

description: In this paper we tackle the problem of dynamic portfolio optimization, i.e., determining the optimal trading trajectory for an investment portfolio of assets over a period of time, taking into account transaction costs and other possible constraints. This problem is central to quantitative finance. After a detailed introduction to the problem, we implement a number of quantum and quantum-inspired algorithms on different hardware platforms to solve its discrete formulation using real data from daily prices over 8 years of 52 assets, and do a detailed comparison of the obtained Sharpe ratios, profits and computing times. In particular, we implement classical solvers (Gekko, exhaustive), D-Wave Hybrid quantum annealing, two different approaches based on Variational Quantum Eigensolvers on IBM-Q (one of them brand-new and tailored to the problem), and for the first time in this context also a quantum-inspired optimizer based on Tensor Networks. In order to fit the data into each specific hardware platform, we also consider doing a preprocessing based on clustering of assets. From our comparison, we conclude that D-Wave Hybrid and Tensor Networks are able to handle the largest systems, where we do calculations up to 1272 fully-connected qubits for demonstrative purposes. Finally, we also discuss how to mathematically implement other possible real-life constraints, as well as several ideas to further improve the performance of the studied methods.

description: Perceiving the world in terms of objects and tracking them through time is a crucial prerequisite for reasoning and scene understanding. Recently, several methods have been proposed for unsupervised learning of object-centric representations. However, since these models were evaluated on different downstream tasks, it remains unclear how they compare in terms of basic perceptual abilities such as detection, figure-ground segmentation and tracking of objects. To close this gap, we design a benchmark with four data sets of varying complexity and seven additional test sets featuring challenging tracking scenarios relevant for natural videos. Using this benchmark, we compare the perceptual abilities of four object-centric approaches: ViMON, a video-extension of MONet, based on recurrent spatial attention, OP3, which exploits clustering via spatial mixture models, as well as TBA and SCALOR, which use explicit factorization via spatial transformers. Our results suggest that the architectures with unconstrained latent representations learn more powerful representations in terms of object detection, segmentation and tracking than the spatial transformer based architectures. We also observe that none of the methods are able to gracefully handle the most challenging tracking scenarios despite their synthetic nature, suggesting that our benchmark may provide fruitful guidance towards learning more robust object-centric video representations.

description: Pig farming is one of the strongest polluters of water resources due to its intensive production techniques and slurry rejection. Several European countries have already introduced environmental regulations aiming at reducing the pollution caused by nitrates from agricultural sources, but not yet Hungary. This paper investigates how Hungarian pig farms would be affected if such regulations are to be enforced. We calculate farm technical efficiency separately for two types of pig production systems – namely farrowing only and farrow-to-finish farms (FAFI farms) and finishing only farms (FI farms) – using 2001 data on pig activity and Data Envelopment Analysis (DEA). We then investigate whether environmental regulations would affect the farms’ technical efficiency, with the help of a second-stage regression and various environmental pressure proxies. Results indicate that the pollution could be reduced with no impact on the output level, and that Hungarian pig farmers have incentives to reduce nitrogen pollution in order to increase their efficiency even in the absence of regulation.

description: Recent advances in the study of electrodisintegration of 3He are presented and discussed. The pair-correlated hyperspherical harmonics method is used to calculate the initial and final state wave functions, with a realistic Hamiltonian consisting of the Argonne v18 two-nucleon and Urbana IX three-nucleon interactions. The model for the nuclear current and charge operators retains one- and many-body contributions. Particular attention is made in the construction of the two-body current operators arising from the momentum-dependent part of the two-nucleon interaction. Three-body current operators are also included so that the full current operator is strictly conserved. The present model for the nuclear current operator is tested comparing theoretical predictions and experimental data of pd radiative capture cross section and spin observables.

description: Waste disposal in the UK is reaching a critical point. Aside from the EU Directive 1999/31/EF requiring a heavy reduction in waste sent to landfill (Jamasb & Nepal, 2010, p.1341), there is a decreasing number of options for landfill sites. New solutions for managing waste will have to be adopted to avoid a situation of needing to export waste for disposal in other countries (Arratia, 2010). In 2004 household waste accounted for around 9% of the total waste produced in the UK (Wastewatch, 2008, p.2), so whilst construction and quarrying still account for the majority of waste creation in the UK, there is a sizeable impact to be made from reducing household waste. Due to a focus in government policy, the volume of household waste has seen a steady decline in the last five years to just over 23 million tonnes, and an increase in the percentage of this that is recycled to 40.1 per cent (DEFRA, 2011, p.1). This is not enough to avert the problems that will exist in the future. Reducing the volume of waste that is produced by households is one of the keys to combatting the waste problem that is being faced by the UK......
Converting to organic farming in France: Is there a selection problem?

description: Using a sample of French crop farms during the 1999-2006 period, we test whether less technically efficient farmers are more likely to engage in organic farming in order to benefit from conversion subsidies. Despite some limitations in our data, we find no evidence of such selection effect. On the contrary, our estimation results indicate that more technically efficient farmers are more likely to convert to organic farming. This finding is found to be robust to the method of calculation of efficiency scores, either parametric or non-parametric. This study also confirms that farm’s characteristics (education, farm size and legal status) and farmers’ practices under conventional farming do impact the probability of conversion to OF.

description: In this paper we present a quantum stochastic model for spectroscopic line-shapes in the presence of a co-evolving and non-stationary background population of excitations. Starting from a field theory description for interacting bosonic excitons, we derive a reduced model whereby optical excitons are coupled to an incoherent background via scattering as mediated by their screened Coulomb coupling. The Heisenberg equations of motion for the optical excitons are then driven by an auxiliary stochastic population variable, which we take to be the solution of an Ornstein-Uhlenbeck process. Itô's Lemma then allows us to easily construct and evaluate correlation functions and response functions. Focusing on the linear response, we compare our model to the classic Anderson-Kubo model. While similar in motivation, there are profound differences in the predicted lineshapes, notably in terms of asymmetry, and variation with increasing background population.
