description: The analysis of the USA 2001 income distribution shows that it can be described by at least two main components, which obey the generalized Tsallis statistics with different values of the q parameter. Theoretical calculations using the gas kinetics model with a distributed saving propensity factor and two ensembles reproduce the empirical data and provide further information on the structure of the distribution, which shows a clear stratification. This stratification is amenable to different interpretations, which are analyzed. The distribution function is invariant with the average individual income, which implies that the inequity of the distribution cannot be modified by increasing the total income.

description: Human beings and their attitudes are at the centre of Social Studies. Interdisciplinary and intersectional aspect of such studies bring forth distinct dynamics that are impactful on the main subjects, which is humans. Correspondingly, feminism or feminist theories require multidimensional approaches in terms of both those who do the study and those who are studied. In other words, interlocking actors and factors should be recognized while taking feminist steps in researches and formal/informal activities. I will analyze bell hook’s Feminism: A Transformational Politic in the light of above said ideas by incorporating my own perception and experience into her arguments through the case-study of Turkey within these arguments. Another point I will touch on is employing both the impact of feminist theories (scholarship) and feminist movements (political activism) on transformations by stressing the importance of the role of unity and solidarity in such transformations.

description: ABSTRACT: Family nurse practitioners (FNPs) have a plethora of employment options upon graduation. Besides primary care, many are working in nontraditional settings such as urgent care, emergency departments, retail health, and specialty practices. In many of these settings, practitioners are required to perform procedures. However, more information is needed on the type of settings in which recent FNP graduates are working, the procedures being performed in these settings, and the perceptions of graduates of how prepared they felt to perform these procedures. Family nurse practitioners who completed an FNP program within the previous five years and who attended the 2019 AANP National Conference were invited to participate in a survey to assess their preparation in clinical procedures. Results revealed that more than half of the 198 respondents reported doing incision and drainage of abscesses and laceration repair. Respondents were divided on how they first learned to perform the procedures, with 47% stating that a preceptor demonstrated procedures to them during a clinical practicum experience, 42% stating that they learned on the job after graduation, and 43% reported that their FNP program provided training or simulation activities related to procedures. More than a quarter of respondents reported that they took a class on procedures. In all, 61% reported that they did not feel adequately prepared to perform procedures on graduation. Results indicated that colleges of nursing should ensure that FNP students have opportunities to master the procedures that are frequently performed by FNPs.
Exclusive C=+ charmonium production in $e^+ e^- \to H+γ$ at B-factories within light cone formalism

description: In this paper the cross sections of the processes $e^+ e^- \to H+γ, H=η_c, η_c', χ_{c0}, χ_{c1}, χ_{c2}$ are calculated. The calculation is carried out at the leading twist approximation of light cone formalism. Within this approach the leading logarithmic radiative and relativistic corrections to the amplitudes are resumed. For the processes $e^+ e^- \to η_c, η_c'+γ$ one loop radiative corrections are taken into account. It is also shown that one loop leading logarithmic radiative corrections calculated within light cone formalism for the processes under study coincide with that obtained by direct calculations of one loop diagrams within nonrelativistic QCD.

A single-stage interleaved resonant power factor correction converter
Creators: name: Saasaa, Raed
Publisher: name: University of British Columbia
Year: 2016

description: Applications requiring DC voltages vary widely, from low power, such as LED lighting, to high power, as in industrial motor drives and battery chargers. Accordingly, a unified power architecture for all applications is not practical for efficiency, size and cost optimization. The use of LED lighting system became popular due to its many advantages. The new outdoor applications such as street and flood lighting require high power (i.e. >200 W) in contrast to the low power existing LED drivers. Generally, the conventional architecture of AC/DC converters consists of two main stages; The first is current-shaping stage to improve PF and the second is to provide isolation and tight regulation over the output voltage. Recently, the research on AC/DC converters has focused on optimizing the converter design to be more reliable and efficient for low and medium power applications. Specifically, techniques have been proposed to eliminate the DC output bus electrolytic capacitor by introducing auxiliary DC/DC converter. On the other hand, the integrated converters were deployed by many researchers to decrease the number of switches, facilitate the controller design, and improve the efficiency. This thesis presents a novel single-stage AC/DC converter that can achieve high power factor with reduced switching losses for semiconductor devices. The topology is derived by integrating the interleaved boost-type PFC and full bridge LLC resonant converters. Due to interleaving at the input, the converter exhibits less input current ripple compared to the existing topologies. Therefore, it is suitable for applications up to approximately 500 W. A detailed analysis of the operation modes is presented. Also, a 350–W prototype is designed to verify the effectiveness of the topology.

description: In 1929, Leo Szilard invented a feedback protocol in which a hypothetical intelligence called Maxwell's demon pumps heat from an isothermal environment and transduces it to work. After an intense controversy that lasted over eighty years; it was finally clarified that the demon's role does not contradict the second law of thermodynamics, implying that we can convert information to free energy in principle. Nevertheless, experimental demonstration of this information-to-energy conversion has been elusive. Here, we demonstrate that a nonequilibrium feedback manipulation of a Brownian particle based on information about its location achieves a Szilard-type information-energy conversion. Under real-time feedback control, the particle climbs up a spiral-stairs-like potential exerted by an electric field and obtains free energy larger than the amount of work performed on it. This enables us to verify the generalized Jarzynski equality, or a new fundamental principle of "information-heat engine" which converts information to energy by feedback control.

description: We propose a field-theoretical approach to a polymer system immersed in an ideal mixture of clustering centers. The system contains several species of these clustering centers with different functionality, each of which connects a fixed number segments of the chain to each other. The field-theory is solved using the saddle point approximation and evaluated for dense polymer melts using the Random Phase Approximation. We find a short-ranged effective inter-segment interaction with strength dependent on the average segment density and discuss the structure factor within this approximation. We also determine the fractions of linkers of the different functionalities.

description: We have made a Galactic extinction map of the Cygnus region with 5' spatial resolution. The selected area is 80^\circ to 90^\circ in the Galactic longitude and -4^\circ to 8^\circ in the Galactic latitude. The intensity at 140 \mum is derived from the intensities at 60 and 100 \mum of the IRAS data using the tight correlation between 60, 100, and 140 \mum found in the Galactic plane. The dust temperature and optical depth are calculated with 5' resolution from the 140 and 100 \mum intensity, and Av is calculated from the optical depth. In the selected area, the mean dust temperature is 17 K, the minimum is 16 K, and the maximum is 30 K. The mean Av is 6.5 mag, the minimum is 0.5 mag, and the maximum is 11 mag. The dust temperature distribution shows significant spatial variation on smaller scales down to 5'. Because the present study can trace the 5'-scale spatial variation of the extinction, it has an advantage over the previous studies, such as the one by Schlegel, Finkbeiner, & Davis, who used the COBE/DIRBE data to derive the dust temperature distribution with a spatial resolution of 1^\circ. The difference of Av between our map and Schlegel et al.'s is \pm 3 mag. A new extinction map of the entire sky can be produced by applying the present method.

description: We study the structure of dynamically generated bound states in the chiral unitary approach. The compositeness of a bound state is defined through the wavefunction renormalization constant in the nonrelativistic field theory. We apply this argument to the chiral unitary approach and derive the relation between compositeness of the bound state and the subtraction constant of the loop integral. The compositeness condition is fairly compatible with the natural renormalization scheme, previously introduced in a different context.

description: We compare different methods for performing analytical continuation of spectral data from the imaginary time or frequency axis to the real frequency axis for the optical conductivity sigma(omega). We compare the maximum entropy (MaxEnt), singular value decomposition (SVD), sampling and Pade methods for analytical continuation. We also study two direct methods for obtaining sigma(0). For the MaxEnt approach we focus on a recent modification. The data are split up in batches, a separate MaxEnt calculation is done for each batch and the results are averaged. For the problems studied here, we find that typically the SVD, sampling and modified MaxEnt methods give comparable accuracy, while the Pade approximation is usually less reliable.

description: The holomorphic invariants introduced by Futaki as obstruction to the asymptotic Chow semistability are studied by an algebraic-geometric point of view and are shown to be the Mumford weights of suitable line bundles on the Hilbert scheme. These invariants are calculated in two special cases. The first is a projective bundle over a curve of genus at least two, and it is shown that it is asymptotically Chow polystable (with every polarization) if and only the underlying vector bundle is slope polystable. This proves a conjecture of Morrison with the extra assumption that the involved polarization is sufficiently divisible. Moreover it implies that a projective bundle is asymptotically Chow polystable (with every polarization) if and only if it admits a constant scalar curvature Kaehler metric. The second case is a manifold blown-up at points, and new examples of asymptotically Chow unstable constant scalar curvature Kaehler classes are given.

Sensitivity analysis and section positioning for road design model
Creators: name: Sarafrazi, Soroor
Publisher: name: University of British Columbia
Year: 2017

description: Economy is one of the most important factors to develop a country and roads are vital to expedite the economy growth. Although road networks lead to social and economic development, the road construction and maintenance are expensive activities. Therefore, there is a strong interest in minimizing the construction cost, while satisfying safety and environmental constraints. Different road design models have been proposed, but the sensitivity of these models to their input parameters has not yet been analyzed. Sensitivity analysis of a road model before building the road is highly suggested because it helps to investigate the stability of the model and identify the parameters that have the most effect on the variability of the model output. In addition, sensitivity analysis helps to enhance the communication between modelers and decision makers (managers). Therefore, different sensitivity analysis methods are presented in this thesis and the sensitivity of a road model to its inputs is studied. Moreover, in a road design model, the ground is discretized into sections and the number of sections is highly correlated with the optimization time. Designing roads that consider all sections is too time consuming to be practical. Thus, different methods are presented in this thesis to reduce the number of sections while keeping the accuracy of the ground profile.

description: Recent ALICE data for the multiplicity distributions in the central rapidity bins at LHC energies are compared with the results from two default versions of the PYTHIA 8 generator. We find that, contrary to the earlier versions of PYTHIA, the model overestimates the increase of average multiplicity with energy. Tuning two of the model parameters one obtains reasonable agreement with data. The dependence of the normalized moments of the distribution on the rapidity bin width and on energy is also qualitatively correct.

Responses of Pacific salmon to pheromones, natal water, and disturbance cues during the spawning migration
Creators: name: Bett, Nolan Nicholas
Publisher: name: University of British Columbia
Year: 2016

description: Olfactory cues can provide many forms of information about an animal’s environment. For some migratory species, these cues guide migrants towards foraging or reproductive grounds. Pacific salmon (Oncorhynchus spp.) use olfactory cues to locate their natal sites during the spawning migration. The objective of this thesis was to further our understanding of the olfactory-mediated movements of Pacific salmon as they return to their home streams to spawn. Through a synthesis of past studies on olfactory navigation in anadromous fish, I identified critical knowledge gaps and future directions for research. Drawing from two long-standing hypotheses that seek to explain how salmonids navigate to their natal sites, I developed a new hypothesis that suggests salmonids use imprinted odours of their natal water as primary directional cues, pheromones as secondary cues, and non-olfactory environmental information as tertiary cues. One of the major implications of this hypothesis is that salmonids that have strayed from their natal migratory route might use pheromones to locate suitable spawning habitat. Using samples I collected from wild adult sockeye salmon (O. nerka), I found increased expression of potential pheromone receptors in strays. I also found that sockeye salmon are behaviourally attracted to the odour of conspecifics when imprinted natal cues are absent, as would be the case for a stray salmon, but not when the imprinted cues are present. Conspecific odours are not always attractive during the migration however, as I found sockeye salmon avoided the odour of conspecifics that were subjected to a handling event, suggesting these fish release chemical disturbance cues when stressed. Pink salmon (O. gorbuscha) did not avoid the odours of disturbed conspecifics, which might relate to species-level differences in life history. Finally, I analyzed the influence of altered flow composition resulting from hydroelectric developments on olfactory navigation in sockeye and pink salmon. Alterations can disorient salmon as they swim upstream, and the results provide guidelines for managers to minimize such disorientation in this river system. The findings of my thesis contribute to our understanding of the olfactory process in salmonids, and point to future research directions in the field of salmonid homing.

description: OBJECTIVE: Intimate partner violence (IPV) is a serious public health threat in the United States, affecting millions of individuals and families. The American Association of Colleges of Nursing recommends that nursing programs, both baccalaureate and graduate, provide students didactic training and clinical experience in the assessment and management of IPV. Our goal was to expose Psychiatric Mental Health Nurse Practitioner (PMHNP) students and Family Nurse Practitioner (FNP) students to a simulated IPV scenario so they are prepared to respond appropriately to a survivor’s disclosure of IPV when they begin clinical practice. METHOD: We integrated a patient simulation scenario into our PMHNP and FNP curriculum. A combined group of PMHNP and FNP students participated in a simulation in which the standardized patient provided an unlikely explanation for her injuries. If students inquired about abuse, the patient revealed that she had experienced IPV. A pre- and posttest survey was used to evaluate student knowledge gain before and after the participating in the scenario. A Related Samples Wilcoxon Signed Rank Test was used to evaluate the results. RESULTS: Compared with pretest scores, students demonstrated improved confidence in screening for IPV as well as responding to a disclosure of IPV. CONCLUSION: Simulation provides a method to enhance student knowledge of incidence, risk, and best practices in relation to the screening, assessment and management of IPV.

description: We report the thermal conductance G of Au/Ti/graphene/SiO2 interfaces (graphene layers 1 < n < 10) typical of graphene transistor contacts. We find G ~ 25 MW m-2 K-1 at room temperature, four times smaller than the thermal conductance of a Au/Ti/SiO2 interface, even when n = 1. We attribute this reduction to the thermal resistance of Au/Ti/graphene and graphene/SiO2 interfaces acting in series. The temperature dependence of G from 50 < T < 500 K also indicates that heat is predominantly carried by phonons through these interfaces. Our findings indicate that metal contacts can limit not only electrical transport, but also thermal dissipation from sub-micron graphene devices.

description: It is shown that the hidden conformal symmetry, namely $SO(2,2) \sim SL(2,R)_L \times SL(2,R)_R$ symmetry, of the non-extremal dyonic Reissner-Nordström black hole can be probed by a charged massless scalar field at low frequencies. The existence of such hidden conformal symmetry suggests that the field theory holographically dual to the 4D Reissner-Nordström black hole indeed should be a 2D CFT. Although the associated AdS$_3$ structure does not explicitly appear in the near horizon geometry, the primary parameters of the dual CFT$_2$ can be exactly obtained without the necessity of embedding the 4D Reissner-Nordström black hole into 5D spacetime. The duality is further supported by comparing the absorption cross sections and real-time correlators obtained from both the CFT and the gravity sides.

description: Weak bases of flavors (u, c), (d,s), (e, μ), (ν_e,ν_μ) are assumed as the S_3 doublet and t, b, τ, {ν_τ} are the S_3 singlet and further there are assumed S_3 doublet Higgs (H_1, H_2) and S_3 singlet Higgs H_S. We suggest an S_3 invariant model in which the Yukawa interactions constructed from these S_3 doublets and singlets are S_3 invariant. In this model, we can explain the quark sector mass hierarchy, quark mixing V_{CKM} and measure of CP violation naturally. In the leptonic sector, neutrino masses are assumed to be constructed through the see-saw mechanism from the Majorana mass. The tri-bimaximal-like character of neutrino mixing V_{MNS} can be explained dynamically without any other symmetry restrictions. It is predicted that a quasi-degenerate mass spectroscopy of neutrino is favorable, and values of |V_{MNS}|_{13}, CP violation invariant measure J and the effective Majorana mass || in neutrino-less double beta decay are not so tiny.

description: This work aims to reveal the role of paraxial protocadherin in otic development, an adhesion protein that has been shown recently to be expressed in otic epithelia. Loss of PAPC leads to morphological failures which result mainly in epithelial disorganisation. XPAPC is necessary to establish apical-basal polarity and thereby maintains epithelial integrity. The most severe alterations can be observed during early development at the invagination process.

This construction is proved to be equivalent to some Manin products of operads and it is shown to be closely related to Rota-Baxter operators. Hence, it gives a new effective way to compute Manin black products. The present construction is shown to have symmetry properties. Finally, this allows us to describe the algebraic structure of square matrices with coefficients in algebras of certain types. Many examples illustrate this text, including the case of Jordan algebras.

description: It is shown that unconventional critical phenomena commonly observed in paramagnetic metals YbRh2Si2, YbRh2(Si0.95Ge0.05)2, and beta-YbAlB4 is naturally explained by the quantum criticality of Yb-valence fluctuations. We construct the mode coupling theory taking account of local correlation effects of f electrons and find that unconventional criticality is caused by the locality of the valence fluctuation mode. We show that measured low-temperature anomalies such as divergence of uniform spin susceptibility $χT^{-ζ)$ with $ζ~0.6$ giving rise to a huge enhancement of the Wilson ratio and the emergence of T-linear resistivity are explained in a unified way.

description: A complete reassessment of the HST observations of the transits of the extrasolar planet HD209458b has provided a transmission spectrum of the atmosphere over a wide range of wavelengths. Analysis of the NaI absorption line profile has already shown that the sodium abundance has to drop by at least a factor of ten above a critical altitude. Here we analyze the profile in the deep core of the NaI doublet line from HST and high-resolution ground-based spectra to further constrain the vertical structure of the HD209458b atmosphere. With a wavelength-dependent cross section that spans more than 5 orders of magnitude, we use the absorption signature of the NaI doublet as an atmospheric probe. The NaI transmission features are shown to sample the atmosphere of HD209458b over an altitude range of more than 6500km, corresponding to a pressure range of 14 scale heights spanning 1 millibar to 1e-9 bar pressures. By comparing the observations with a multi-layer model in which temperature is a free parameter at the resolution of the atmospheric scale height, we constrain the temperature vertical profile and variations in the Na abundance in the upper part of the atmosphere of HD209458b. We find a rise in temperature above the drop in sodium abundance at the 3mbar level. We also identify an isothermal atmospheric layer at 1500+/-100K spanning almost 6 scale heights in altitude, from 1e-5 to 1e-7 bar. Above this layer, the temperature rises again to 2500(+1500/-1000)K at 1e-9 bar, indicating the presence of a thermosphere. The resulting temperature-pressure (T-P) profile agrees with the Na condensation scenario at the 3 mbar level, with a possible signature of sodium ionization at higher altitudes, near the 3e-5 bar level. Our T-P profile is found to be in good agreement with the profiles obtained with aeronomical models including hydrodynamic escape.

description: [Objectives] To explore the niche characteristics of herbaceous plants under Pinus tabuliformis plantation forest in the feldspathic sandstone area, and to provide basic data for maintaining biodiversity and community stability in the local P. tabuliformis plantation forest. [Methods] The types, quantity, average plant height, and coverage of various herbaceous plants were recorded by field survey in a well-growing P. tabulaeformis forest area. Based on the survey data, Shannon and Levins niche breadth index, Levins niche overlap index and ecological response were used to analyze the niche characteristics of herbaceous plants under P. tabulaeformis plantation forest. [Results] (i) There were 35 species of herbaceous plants in the P. tabulaeformis plantation forest in the feldspathic sandstone area. Among them, Stipa bungeiensis had the largest niche breadth indexes with better performance. Because of its strong adaptability, its community was in an obviously advantageous position. (ii) The overall niche width and niche overlap index were generally not high, and understory herb species showed differentiation. (iii) Among the understory herbaceous species, 37.15% of the species were developed species, and 62.86% of the species were declining species. Among the 14 dominant species, 11 were developmental species. The species with largest the resource occupancy were S. bungeiensis (0.188 5), Heteropappus altaicus (0.053 1), and Cleistogenes squarrosa (0.037 9). [Conclusions] Competition among under herbaceous plants in P. tabulaeformis plantation forest in the feldspathic sandstone area was weak, and the community species had poor utilization of resources and environment. Most of the dominant herbaceous species were in the developing stage, indicating that the P. tabulaeformis plantation community tends to be relatively stable at the current stage.
Lived experience of mattering in teachers : a phenomenological inquiry
Creators: name: Campbell, Jodi

description: The concept of interpersonal mattering, or one’s perceived significance in the lives of others, has demonstrated importance in the success and well-being of students. This construct, however, has yet to be adequately explored in the teachers who are responsible for creating mattering environments for their students. The purpose of this study was to explore the meaning of teachers’ lived experiences of mattering in the workplace. The aim was to improve understanding of this phenomenon so that teachers and employers may have a greater understanding of the ways in which mattering may impact teachers’ satisfaction and their ability to support students. Participants included six full-time teachers from a variety of different settings. An in-depth interview and a follow-up member check was conducted with each participant. Interpretative phenomenology was used to gain a rich understanding of the essential meanings of the mattering experience from the teachers’ descriptions of their lived experiences. The following three essential themes were uncovered; impacting students, being seen, and belonging to a community.

description: At today's stock markets, most of the trading volume is traded 
electronically. Thus, also many market participants execute their 
order flow automatically with the help of trading algorithms. Hence, 
several important aspects concerning algorithmic trading are 
discussed. One of the main topics of the current work is the 
measurement and the analysis of the market impact of transactions 
performed by a trading algorithm. Another main topic is a model 
to predict the intraday trading volume.

description: In this thesis we study several aspects of new physics (NP) in rare hadronic B decays: First we analyse tan(beta)-enhanced corrections in the Minimal Supersymmetric Standard Model (MSSM). We generalise the known resummation formulas beyond the decoupling limit and study novel effects in couplings involving genuine SUSY particles. In the second part of the thesis we discuss the possibility of probing NP in electroweak penguins via the purely isospin-violating decays B_s->phi,pi(rho).

Formation of Multiple Populations in Globular Clusters: Another Possible Scenario

description: While chemical composition spreads are now believed to be a universal characteristic of globular clusters (GCs), not all of them present multiple populations in their color-magnitude diagrams (CMDs). Here we present a new scenario for the formation of GCs, in an attempt to qualitatively explain this otherwise intriguing observational framework. Our scenario divides GCs into three groups, depending on the initial mass (M_I) of the progenitor structure (PS), as follows. i) Massive PSs can retain the gas ejected by massive stars, including the ejecta of core-collapse SNe. ii) Intermediate-mass PSs can retain at least a fraction of the fast winds of massive stars, but none of the core-collapse SNe ejecta. iii) Low-mass PSs can only retain the slow winds of intermediate-mass stars. Members of the first group would include omega Centauri (NGC 5139), M54 (NGC 6715), M22 (NGC 6656), and Terzan 5, whereas NGC 2808 (and possibly NGC 2419) would be members of the second group. The remaining GCs which only present a spread in light elements, such as O and Na, would be members of the third group. According to our scenario, the different components in omega Cen should not display a sizeable spread in age. We argue that this is consistent with the available observations. We give other simple arguments in favor of our scenario, which can be described in terms of two main analytical relations: i) Between the actual observed ratio between first and second generation stars (R_SG^FG) and the fraction of first generation stars that have been lost by the GC (S_L); and ii) Between S_L and M_I. We also suggest a series of future improvements and empirical tests that may help decide whether the proposed scenario properly describes the chemical evolution of GCs.

description: We demonstrate a reliable technique for counting atomic planes (n) of few-layer graphene (FLG) on SiO2/Si substrates by Raman spectroscopy. Our approach is based on measuring the ratio of the integrated intensity of the G graphene peak and the optical phonon peak of Si, I(G)/I(Si), and is particularly useful in the range n>4 where few methods exist. We compare our results with atomic force microscopy (AFM) measurements and Fresnel equation calculations. Lastly, we apply our method to unambiguously identify n of FLG devices and find that the mobility (~2000 cm2 V-1 s-1) is independent of layer thickness for n>4.
