description: The canonical observation mode for IACT gamma-ray observations employs four discrete pointings in the cardinal directions (the "wobble" mode). For the VERITAS Observatory, the target source is offset by 0.5-0.7 degrees from the camera center, and the observation lasts 20 minutes. During January/February of 2011, the VERITAS Observatory tested a new "orbit" observation mode, where the target source is continuously rotated around the camera center at a fixed radial offset and constant angular velocity. This mode of observation may help better estimate the cosmic ray background across the field of view, and will also reduce detector dead-time between the discrete 20 minute runs. In winter 2011, orbit mode observations where taken on the Crab Nebula and Mrk 421. In this paper we present the analysis of these observations, and describe the potential applications of orbit mode observations for diffuse (extended) sources as well as GRBs.

description: This paper explores a water supply index calculated from the present year's discharge and discharges in previous years. The paper also compares the use of a water supply index to the use of a single year as a method of classifying annual streamflows into water year classes for the purpose of allocating water to environmental flows. The third task compares the return periods of low annual flows to return periods of a low water supply index. The Cache la Poudre River in Colorado is used as a case study. The water supply index (WSI) is calculated using the equation WSI = {Q(I) + 0.5 Q(I-1) + 0.25 Q(I-2)}/1.75. The index does improve the classification of years into five classes of water years: very dry, dry, moderate dry, moderate wet, and wet. The classification using the water supply index as compared to using annual streamflows only appears to improve the ability of water manages to respond to low flow conditions. The deregulated streamflows in the Cache la Poudre River were analyzed and the 2002 year streamflows were found to have a return period of the annual discharge based on a log-Pearson Type III analysis of 426 years. For the water supply index the return period is 403 years. A long period record has been generated by NOAA using tree rings for 1615-1999. Using a long period record based on tree ring analysis (1615-1999) and deregulated streamflows (2000-2009) the return period for the annual discharge in 2002 is 58 years and 186 years for the water supply index.

In theory, a change in control only makes sense when the value of the firm to new owners, minus transaction costs, is greater than the value of the firm to current owners. This Quick Guide examines the market for corporate control. It answers the questions: Why do companies merge? Do mergers improve performance? Who gets the value in a merger? How do companies protect themselves from hostile bids? Do these protections help shareholders?

description: We study the realization of non-Abelian discrete gauge symmetries in 4d field theory and string theory compactifications. The underlying structure generalizes the Abelian case, and follows from the interplay between gaugings of non-Abelian isometries of the scalar manifold and field identifications making axion-like fields periodic. We present several classes of string constructions realizing non-Abelian discrete gauge symmetries. In particular, compactifications with torsion homology classes, where non-Abelianity arises microscopically from the Hanany-Witten effect, or compactifications with non-Abelian discrete isometry groups, like twisted tori. We finally focus on the more interesting case of magnetized branes in toroidal compactifications and quotients thereof (and their heterotic and intersecting duals), in which the non-Abelian discrete gauge symmetries imply powerful selection rules for Yukawa couplings of charged matter fields. In particular, in MSSM-like models they correspond to discrete flavour symmetries constraining the quark and lepton mass matrices, as we show in specific examples.

Essays on the political economy of local Brazilian governments
Creators: name: Fujiwara, Thomas
Publisher: name: University of British Columbia
Year: 2011

description: Recent research has stressed the role of political institutions in economic development. This thesis aims at shedding light on this issue by empirically analyzing the political determinants of policymaking and its consequences to living standards in a developing economy setting. Each of its three chapters presents a separate essay. The first chapter addresses how the political participation of disadvantaged groups can be fostered. It studies the introduction of electronic technology that facilitated voting for the less educated in Brazilian elections. Using a regression discontinuity design embedded in its phase-in, it provides evidence that electronic voting reduced residual (uncounted) votes and generated the de facto enfranchisement of a large fraction of the less educated (poorer) parts of the electorate. The second chapter tests if this additional political participation of poorer voters shifted public policymaking in a way that benefited them. It finds evidence that electronic voting increased the number of state legislators that are themselves less educated and shifted government spending towards public health care, a government policy that disproportionately benefits the less educated, leading to improved utilization (number of pre-natal visits) and lower prevalence of low-weight births in this group. No effects on health care utilization by the more educated and on the weight of their newborns are found, suggesting that electronic voting indeed empowered the less educated. Lastly, the third chapter addresses the empirical relevance of strategic voting, a key issue in theoretical and policy analysis of political institutions. It uses exogenous variation in electoral rules to test the predictions of strategic voting models and the causal validity of Duverger's Law. Estimations based on a regression discontinuity design in the assignment of single-ballot and dual-ballot electoral systems in Brazilian mayoral races indicate that, in accordance to Duverger's Law, single-ballot plurality rule causes voters to desert third placed candidates and vote for the two most popular ones. It finds that the effects are stronger in close elections, and that candidates' characteristics and entry cannot account for the results, suggesting that strategic voting is the driving force behind these findings.
Gluon mass through ghost synergy

description: In this work we compute, at the "one-loop-dressed" level, the nonperturbative contribution of the ghost loops to the self-energy of the gluon propagator, in the Landau gauge. This is accomplished within the PT-BFM formalism, which guarantees the gauge-invariance of the emerging answer. In particular, the contribution of the ghost-loops is automatically transverse, by virtue of the QED-like Ward identities satisfied in this framework. Using as nonperturbative input the available lattice data for the ghost dressing function, we show that the ghost contributions have a rather sizable effect on the overall shape of the gluon propagator, both for $d=3,4$. Then, by exploiting a recently introduced dynamical equation for the effective gluon mass, whose solutions depend crucially on the characteristics of the gluon propagator at intermediate energies, we show that if the ghost loops are removed from the gluon propagator then the gluon mass vanishes. These findings strongly suggest that, at least at the level of the Schwinger-Dyson equations, the effects of gluons and ghosts are inextricably connected, and must be combined suitably in order to reproduce the results obtained in the recent lattice simulations.

description: We derive a geometrical expression of the excess entropy production for quasi-static transitions between nonequilibrium steady states of Markovian jump processes, which can be exactly applied to nonlinear and nonequilibrium situations. The obtained expression is geometrical; the excess entropy production depends only on a trajectory in the parameter space, analogous to the Berry phase in quantum mechanics. Our results imply that vector potentials are needed to construct thermodynamics of nonequilibrium steady states.
What's in a grade? The multidimensional nature of what teacher-assigned grades assess in high school

description: Historically, teacher-assigned grades have been seen as unreliable subjective measures of academic knowledge, since grades and standardized tests have traditionally correlated at about the 0.5 to 0.6 level, and thus explain about 25–35% of each other. However, emerging literature indicates that grades may be a multidimensional assessment of both student academic knowledge and a student's ability to negotiate the social processes of schooling, such as behavior, participation, and effort. This study analyzed the high school transcript component of the Education Longitudinal Study of 2002 (ELS:2002) using multidimensional scaling (MDS) to describe the relationships between core subject grades, non-core subject grades, and standardized test scores in mathematics and reading. The results indicate that when accounting for the academic knowledge component assessed through standardized tests, teacher-assigned grades may be a useful assessment of a student's ability at the non-cognitive aspects of school. Implications for practice, research, and policy are discussed.

description: We propose a scheme for the generation of entangled states for two atoms trapped in separate cavities coupled to each other. The scheme is based on the competition between the unitary dynamics induced by the classical fields and the collective decays induced by the dissipation of two delocalized field modes. Under certain conditions, the symmetric or asymmetric entangled state is produced in the steady state. The analytical result shows that the distributed steady entanglement can be achieved with high fidelity independent of the initial state, and is robust against parameter fluctuations. We also find out that the linear scaling of $F$ has a quadratic improvement compared to distributed entangled state preparation protocols based on unitary dynamics.

description: We evaluate the degree of quantum correlation between two fermions (bosons) subject to continuous time quantum walks in a one-dimensional ring lattice with periodic boundary conditions. In our approach, no particle-particle interaction is considered. We show that the interference effects due to exchange symmetry can result into the appearance of non-classical correlations. The role played onto the appearance of quantum correlations by the quantum statistics of the particles, the boundary conditions, and the partition of the system is widely investigated. Quantum correlations also been investigated in a model mimicking the ballistic evolution of two indistinguishable particles in a 1D continuous space structure. Our results are consistent with recent quantum optics and electron quantum optics experiments where the showing up of two-particle non-classical correlations has been observed even in the absence of mutual interaction between the particles.

description: An effective approach to estimate the Manning's roughness in a river is to select a grain roughness value of Manning's n for the bed material and then add other components of roughness to the grain roughness. The grain roughness is represented by the size and shape of the grains of the material that form the stream bed. Cross section irregularities, channel alignment, vegetation, obstructions, and other factors that increase roughness and added to the grain roughness. The objective of this paper is to improve on ability to calculate grain roughness in gravel-bed rivers where the grain roughness is represented by Manning's roughness. Equations developed by G.A. Griffiths are considered to be equations that can be used to estimate the grain roughness. A method of estimating grain roughness using quantile regression shows comparable results to the Griffiths equations based on the Griffiths data and another set of data from Northern California. Data from Arizona and New York was also used to develop equations for grain roughness. These equations are very different from the Griffiths equations. A discussion of a possible reason for difference in the different equations for grain roughness is presented.

description: Observed patterns of genetic structure result from the interactions of demographic, physical, and historical influences on gene flow. The particular strength of various factors in governing gene flow, however, may differ between species in biologically relevant ways. We investigated the role of demographic factors (population size and sex-biased dispersal) and physical features (geographic distance, island size and climatological winds) on patterns of genetic structure and gene flow for two lineages of Greater Antillean bats. We used microsatellite genetic data to estimate demographic characteristics, infer population genetic structure, and estimate gene flow among island populations of Erophylla sezekorni/E. bombifrons andMacrotus waterhousii (Chiroptera: Phyllostomidae). Using a landscape genetics approach, we asked if geographic distance, island size, or climatological winds mediate historical gene flow in this system. Samples from 13 islands spanning Erophylla's range clustered into five genetically distinct populations. Samples of M. waterhousii from eight islands represented eight genetically distinct populations. While we found evidence that a majority of historical gene flow between genetic populations was asymmetric for both lineages, we were not able to entirely rule out incomplete lineage sorting in generating this pattern. We found no evidence of contemporary gene flow except between two genetic populations of Erophylla. Both lineages exhibited significant isolation by geographic distance. Patterns of genetic structure and gene flow, however, were not explained by differences in relative effective population sizes, island area, sex-biased dispersal (tested only for Erophylla), or surface-level climatological winds. Gene flow among islands appears to be highly restricted, particularly for M. waterhousii, and we suggest that this species deserves increased taxonomic attention and conservation concern.

description: Here we calibrate the carbonate clumped isotope thermometer in modern deep-sea corals. We examined 11 specimens of three species of deep-sea corals and one species of a surface coral spanning a total range in growth temperature of 2–25 °C. External standard errors for individual measurements ranged from 0.005‰ to 0.011‰ (average: 0.0074‰) which corresponds to ∼1–2 °C. External standard errors for replicate measurements of Δ47 in corals ranged from 0.002‰ to 0.014‰ (average: 0.0072‰) which corresponds to 0.4–2.8 °C. We find that skeletal carbonate from deep-sea corals shows the same relationship of Δ47 (the measure of 13C–18O ordering) to temperature as does inorganic calcite. In contrast, the δ13 C and δ18O values of these carbonates (measured simultaneously with Δ47 for every sample) differ markedly from equilibrium with seawater; i.e., these samples exhibit pronounced ‘vital effects’ in their bulk isotopic compositions. We explore several reasons why the clumped isotope compositions of deep-sea coral skeletons exhibit no evidence of a vital effect despite having large conventional isotopic vital effects.

description: The first Search for Extra-Terrestrial Intelligence (SETI) conducted with Very Long Baseline Interferometry (VLBI) is presented. By consideration of the basic principles of interferometry, we show that VLBI is efficient at discriminating between SETI signals and human generated radio frequency interference (RFI). The target for this study was the star Gliese 581, thought to have two planets within its habitable zone. On 2007 June 19, Gliese 581 was observed for 8 hours at 1230-1544 with the Australian Long Baseline Array. The dataset was searched for signals appearing on all interferometer baselines above five times the noise limit. A total of 222 potential SETI signals were detected and by using automated data analysis techniques, were ruled out as originating from the Gliese 581 system. From our results we place an upper limit of 7 MW/Hz on the power output of any isotropic emitter located in the Gliese 581 system, within this frequency range. This study shows that VLBI is ideal for targeted SETI, including follow-up observations. The techniques presented are equally applicable to next-generation interferometers, such as the long baselines of the Square Kilometre Array (SKA).

description: This volume presents three research papers. In Chapter 1 I analyze whether an inter­national technological agreement to develop and adopt a breakthrough technology can perform better than an international abatement agreement if an international market for the breakthrough technology is created. In the model presented, it is assumed that countries can form two international consortiums: i) a producing consortium that devel­ops and sells the technology to outsiders and ii) a consuming consortium that chooses whether to buy and adopt the technology. Depending on the size of the gains from cooperation, two different outcomes are possible. If the gains are small, the adoption of the technology is incomplete. However, when the gains are sufficiently large, the producing consortium can apply a market mechanism that solves the free-riding prob­lem among countries, allowing full adoption of the technology resulting in a significant global welfare improvement. In Chapter 2 I analyze an economy with two types of environmental externalities, pollution and abatement externalities. Abatement activities in each sector depend on the level of abatement investment in that sector and the aggregate abatement activity in the economy. I show that when there are sufficient policy instruments to target the externalities, it can be in the interest of groups to lobby in favour of other sectors. I also show that an increase in the political influence of environmentalists does not necessarily result in a higher pollution tax and, under certain circumstances, it is in the interest of environmentalists to support polluting sectors. In Chapter 3 I present an empirical study using time series analysis that investigates the price relationships between the American and the European markets for oil and major refined products. The econometric evidence supports the hypothesis that the American and European markets for oil and refined products are integrated. Moreover, the results suggest that a structural break occurred during the financial crisis of 2008, changing the long-run equilibrium price relationships and the short-run price dynamics. Taking into account this structural break, for each pair of prices I estimate the long-run equilibrium relationship and the error correction model to characterize the short-run price dynamic between the European and American markets.

description: The reclamation of salinized soil involves lowering ground water levels, draining the vadose zone, and leaching the salts from the root zone. Plastic drain tubing placed 1.5 to 1.8 m below the land surface can lower watertables and drain phreatic water, but irrigation is usually required to leach the offending salts. The leaching process in non-irrigated drylands depends on natural precipitation. Rows of tall wheatgrass, Thinopyrum ponticum (Podp.) Lui & Wang, (1.2 m mean height) spaced on 15.2-m centers across saline fields can retain blowing snow, augment water for leaching salts, and moderate evapotranspiration when grown in conjunction with subsurface drainage. The mean salinity of saturated soil paste extracts from sets of soil samples taken every fall from such a site in southwestern Saskatchewan averaged 14.1 dS m-1 during 1985- 90 before the drainage was installed, 13.0 dS m-1 for 1991-92 after drainage but before the grass windbreaks became established, and 9.6 dS m-1 for 1993-98 with both drainage and windbreaks in place.

This work describes BAMBI--a sequential Monte Carlo motif identification algorithm, which is based on a position weight matrix model that does not require additional constraints and is able to estimate such motif properties as length, logo, number of instances and their locations solely on the basis of primary nucleotide sequence data. Furthermore, should biologically meaningful information about motif attributes be available, BAMBI takes advantage of this knowledge to further refine the discovery results. In practical applications, we show that the proposed approach can be used to find sites of such diverse DNA-binding molecules as the cAMP receptor protein (CRP) and Din-family site-specific serine recombinases. Results obtained by BAMBI in these and other settings demonstrate better statistical performance than any of the four widely-used profile-based motif discovery methods: MEME, BioProspector with BioOptimizer, SeSiMCMC and Motif Sampler as measured by the nucleotide-level correlation coefficient. Additionally, in the case of Din-family recombinase target site discovery, the BAMBI-inferred motif is found to be the only one functionally accurate from the underlying biochemical mechanism standpoint.

description: This study aimed at substantiating the associations of the apolipoproein M gene (APOM) with type 2 diabetes (T2D) as well as with metabolic traits in Hong Kong Chinese. In addition, APOM gene function was further characterized to elucidate its activity in cholesterol metabolism. Seventeen APOM SNPs documented in the NCBI database were genotyped. Five SNPs were confirmed in our study cohort of 1234 T2D and 606 control participants. Three of the five SNPs rs707921(C+1871A), rs707922(G+1837T) and rs805264(G+203A) were in linkage disequilibrium (LD). We chose rs707922 to tag this LD region for down stream association analyses and characterized the function of this SNP at molecular level. No association between APOM and T2D susceptibility was detected in our Hong Kong Chinese cohort. Interestingly, the C allele of rs805297 was significantly associated with T2D duration of longer than 10 years (OR = 1.245, p = 0.015). The rs707922 TT genotype was significantly associated with elevated plasma total- and LDL- cholesterol levels (p = 0.006 and p = 0.009, respectively) in T2D patients. Molecular analyses of rs707922 lead to the discoveries of a novel transcript APOM5 as well as the cryptic nature of exon 5 of the gene. Ectopic expression of APOM5 transcript confirmed rs707922 allele-dependent activity of the transcript in modifying cholesterol homeostasis in vitro. In conclusion, the results here did not support APOM as a T2D susceptibility gene in Hong Kong Chinese. However, in T2D patients, a subset of APOM SNPs was associated with disease duration and metabolic traits. Further molecular analysis proved the functional activity of rs707922 in APOM expression and in regulation of cellular cholesterol content.
Forecasting residual demand in markets with significant wind power penetration

description: This thesis addresses the issue of better forecasts of residual electrical power demand. Residual demand is total electric power load demand minus total renewable energy gen­eration. The key player in volatile and uncertain renewable energy generation is wind power. It is usually accommodated into the grid on the basis of priority being given to green energy. Thus, residual load is more volatile and uncertain than total electric load. Existing methods for determining future residual demand do not always produce very accurate results. Therefore, a new method is proposed. To test it, two markets with signifi­cant wind power penetration are chosen. Testing the proposed approach using a new residual demand forecast model is the main focus of the thesis. Also, testing the models developed for load and wind power forecast is an objective. To know the practicality of the developed models, numerical results are compared against the forecasts generated by the independent system operators of the electricity mar­kets, whenever such forecasts were available.

description: There is a consistent demand for new biosensors for the detection of protein targets, and a systematic method for the rapid development of new sensors is needed. Here we present a platform where short unstructured peptides that bind to a desired target are selected using M13 phage display. The selected peptides are then chemically synthesized and immobilized on gold, allowing for detection of the target using electrochemical techniques such as electrochemical impedance spectroscopy (EIS). A quartz crystal microbalance (QCM) is also used as a diagnostic tool during biosensor development. We demonstrate the utility of this approach by creating a novel peptide-based electrochemical biosensor for the enzyme alanine aminotransferase (ALT), a well-known biomarker of hepatotoxicity. Biopanning of the M13 phage display library over immobilized ALT, led to the rapid identification of a new peptide (ALT5-8) with an amino acid sequence of WHWRNPDFWYLK. Phage particles expressing this peptide exhibited nanomolar affinity for immobilized ALT (Kd,app = 85±20 nM). The newly identified ALT5-8 peptide was then chemically synthesized with a C-terminal cysteine for gold immobilization. The performance of the gold-immobilized peptides was studied with cyclic voltammetry (CV), QCM, and EIS. Using QCM, the sensitivity for ALT detection was 8.9±0.9 Hz/(μg/mL) and the limit of detection (LOD) was 60 ng/mL. Using EIS measurements, the sensitivity was 142±12 impedance percentage change %/(μg/mL) and the LOD was 92 ng/mL. In both cases, the LOD was below the typical concentration of ALT in human blood. Although both QCM and EIS produced similar LODs, EIS is preferable due to a larger linear dynamic range. Using QCM, the immobilized peptide exhibited a nanomolar dissociation constant for ALT (Kd = 20.1±0.6 nM). These results demonstrate a simple and rapid platform for developing and assessing the performance of sensitive, peptide-based biosensors for new protein targets.

description: We study the probability distribution of the pseudo-critical temperature in a mean-field and in a short-range spin-glass model: the Sherrington-Kirkpatrick (SK) and the Edwards-Anderson (EA) model. In both cases, we put in evidence the underlying connection between the fluctuations of the pseudo-critical point and and the Extreme Value Statistics of random variables. For the SK model, both with Gaussian and binary couplings, the distribution of the pseudo-critical temperature is found to be the Tracy-Widom distribution. For the EA model, the distribution is found to be the Gumbel distribution. Being the EA model representative of uniaxial magnetic materials with quenched disorder like $Fe_{0.5} Mn_{0.5} Ti O_3$ or $Eu_{0.5} Ba_{0.5} Mn O_3$, its pseudo-critical point distribution should be a priori experimentally accessible.

description: We report the first in vivo use of optical coherence tomography (OCT), a high-resolution (~10 µm) real-time imaging technology, to scan subendocardial tissue and to monitor radiofrequency (RF) lesion formation. Endocardial imaging during an open chest procedure in a female pig was conducted with a forward imaging catheter with a Fourier Domain OCT system at 20 frames per second. Images of the endocardial surface and subendocardial tissue were obtained when the catheter was in direct contact with the endocardial surface. The formation and progressive increase in size of cavities within the myocardium were observed in the OCT images when a steam pop was audible. Our initial findings suggest that imaging with a forward scanning OCT catheter can assess tip electrode–tissue interface contact, image subsurface myocardial structure, and visualize dynamic effects of intramural RF energy delivery.
“Members of the Same Club”: Challenges and Decisions Faced by US IRBs in Identifying and Managing Conflicts of Interest

description: Conflicts of interest (COIs) in research have received increasing attention, but many questions arise about how Institutional Review Boards (IRBs) view and approach these. Methods: I conducted in-depth interviews of 2 hours each with 46 US IRB chairs, administrators, and members, exploring COI and other issues related to research integrity. I contacted leaders of 60 IRBs (every fourth one among the top 240 institutions by NIH funding), and interviewed IRB leaders from 34 of these institutions (response rate = 55%). Data were analyzed using standard qualitative methods, informed by Grounded Theory. Results: IRBs confront financial and non-financial COIs of PIs, institutions, and IRBs themselves. IRB members may seek to help, or compete with, principal investigators (PIs). Non-financial COI also often appear to be “indirect financial” conflicts based on gain (or loss) not to oneself, but to one's colleagues or larger institution. IRBs faced challenges identifying and managing these COI, and often felt that they could be more effective. IRBs' management of their own potential COI vary, and conflicted members may observe, participate, and/or vote in discussions. Individual IRB members frequently judge for themselves whether to recuse themselves. Challenges arise in addressing these issues, since institutions and PIs need funding, financial information is considered confidential, and COI can be unconscious. Conclusions: This study, the first to explore qualitatively how IRBs confront COIs and probe how IRBs confront non-financial COIs, suggests that IRBs face several types of financial and non-financial COIs, involving themselves, PIs, and institutions, and respond varyingly. These data have critical implications for practice and policy. Disclosure of indirect and non-financial COIs to subjects may not be feasible, partly since IRBs, not PIs, are conflicted. Needs exist to consider guidelines and clarifications concerning when and how, in protocol reviews, IRB members should recuse themselves from participating, observing, and/or voting.
