Symptomatology, life events, and coping strategies in seasonal affective disorder
Creators: name: Brown, Charlotte
Publisher: name: American University
Year: 2023

description: This study examined changes in depressive symptoms, major life stressors, daily minor stressors, cognitive appraisal of stressful events, and coping strategies used in stressful episodes across seasons in depressed subjects and non-depressed controls. Thirty-seven subjects diagnosed with winter seasonal affective disorder (SAD) and 29 nondepressed normal controls were evaluated at two time periods, during the fall/winter months and during the spring/summer months. All subjects with SAD met criteria for a current major depressive episode according to DSM III-R criteria at the time of the study. The majority of SAD subjects showed complete symptom remission on follow-up evaluation; four of the 37 subjects remained depressed on follow-up. Contrary to prediction, SAD subjects did not differ from non-depressed controls in the number of major life stressors experienced in the months prior to their depressive episode, nor did the number of stressors show a significant decrease across seasons. SAD subjects reported more minor stressors on initial evaluation than controls, but showed a significant decrease on follow-up. A similar pattern was observed across seasons in SAD subjects' rating of the severity of these stressors. SAD subjects reported a significant decrease in severity of stressors from winter to summer. However, when compared with controls, they rated stressors as significantly more severe at both time periods. SAD subjects did not differ from controls in how they evaluated the significance of a stressful encounter (primary appraisal) or in their assessment of available resources or coping options (secondary appraisal). However, there was a trend for SAD subjects to be more concerned about threats to self esteem than controls when coping with stressful situations, regardless their level of depression. In addition, both SAD subjects and controls showed an increase in their concern about losing respect for others on follow-up evaluation. However, only SAD subjects showed a significant increase from Time 1 to Time 2. When coping with stressful situations SAD subjects used significantly more escape-avoidance coping when depressed than when symptoms had remitted. They differed from controls when depressed but not on follow-up. There was a trend for SAD subjects to use less Positive Reappraisal when depressed than on remission.

description: One-loop radiative corrections will lead to a small difference between the matter potentials developed by $ν_μ^{}$ and $ν_τ$ when they travel in a medium. By including such radiative corrections, we derive the exact expressions of the corresponding effective mass-squared differences and the moduli square of the lepton flavor mixing matrix elements $|\widetilde U_{αi}^{}|^2$ (for $α=e,μ,τ$ and $i=1,2,3$) in matter in the standard three-flavor mixing scheme and focus on their asymptotic behaviors when the matter density is very big (i.e., the matter effect parameter $A\equiv 2\sqrt{2} G_{\rm F}^{} N_e^{}E$ is very big). Different from the non-trivial fixed value of $|\widetilde U_{αi}^{}|^2$ in the $A\to \infty$ limit in the case without radiative corrections, we get $|\widetilde U_{αi}^{}|^2=0~{\rm or}~1$ under this extreme condition. The radiative corrections can significantly affect the lepton flavor mixing in dense matter, which are numerically and analytically discussed in detail. Furthermore, we also extend the discussion to the $(3+1)$ active-sterile neutrino mixing scheme.

description: The Yang-Mills equations generalize Maxwell's equations to nonabelian gauge groups, and a quantity analogous to charge is locally conserved by the nonlinear time evolution. Christiansen and Winther observed that, in the nonabelian case, the Galerkin method with Lie algebra-valued finite element differential forms appears to conserve charge globally but not locally, not even in a weak sense. We introduce a new hybridization of this method, give an alternative expression for the numerical charge in terms of the hybrid variables, and show that a local, per-element charge conservation law automatically holds.

description: Global sales of organic food and drink reached $80 billion in 2014, a more than four-fold market expansion since 2000 ($18 billion in organic sales). Demand for organic products is concentrated in North America and Europe, which create 96% of global revenues. Organic production expanded during the 1980s, with different certifiers developing their own standards and certification processes. Since that time, the industry has grown from experimental garden plots to large farms with surplus products sold under a special organic label. In the United States, sales of organic products topped $35 billion (USD) in 2013 (an increase of 11.5% from 2012) and grew by more than 11% in 2015. Market development in this area could enhance both the net profits and the sustainability of small farms by serving the organic niche market. This study profiles a typical organic consumer in the mid-Atlantic United States. An online survey was conducted to capture organic consumers’ interests in and expectations of organic fruits and vegetables. Data were collected through an online survey of 1,100 participants who were pre-screened and whose identities were checked from a selection of 5,191 candidates provided by a private online survey company. We developed a multinomial logit model to predict organic consumers’ choice of fresh fruits and vegetables. The seven most important fruits and vegetables were identified for this study, the rest were included in the “other” category. The choice of “other” fruits and vegetables has been left out of the regression as the base case. Results show that consumers who think that organic food tastes better and consumers who are college graduates are more likely to choose bananas compared to other fruits and vegetables. Respondents who are concerned about freshness, provide support to local farmers, have a two-year college degree, and are Caucasian are more likely to choose carrots. Those who provide support to local farmers and who have an education above high school are more likely to choose lettuce. Respondents with a two-year college degree are more likely to choose strawberries, while those who prefer organic wine are more likely to choose apples. Caucasians are more likely to choose tomatoes but less likely to choose spinach. Those living in urban areas are less likely to choose spinach. Producers of organic fruits and vegetables can target customers for sales based on their demographics and their preferences.

description: The chosen design replaces the current 2-way stop intersection at Marine Drive and Chancellor Boulevard with a single-lane roundabout that includes a separated pedestrian viewing platform. The cost of the project is expected to be $1.7M with a 6 month construction period from May - October 2016. The new intersection will create a safe and user friendly environment befitting of a UBC gateway. The design emphasizes alternative forms of travel, Musqueam partnership, and user safety. For increases in traffic volume during construction, such as the May graduation ceremony, careful planning will ensure that congestion is minimized. The designed single-lane roundabout utilizes a 40 meter diameter circle and is capable of efficiently handling the projected maximum flow for the 15 year design life. All incoming lanes will have their alignment and width adjusted to incorporate the new roundabout and promote more green space. Bicyclists will be able to use the marked bicycle lanes on all roads and pedestrians will be able to access one of the four signalized crosswalks on each corner; making it user-friendly for all forms of travel. The added green space and signage will revamp the area and give it a modern gateway feel. The viewing platform will overlook the North Shore mountains and the Burrard Inlet, use sustainable construction material, and will incorporate a Musqueam inspired design. A call for local Musqueam artists will be made to promote community building and ensure that the native community has a voice in the project. The 7 meter high platform, which has a 358 m2 ground area, will be supported by hidden concrete retaining walls. Timber composite beams and cross-laminated timber panels will be exposed on the facade. The stormwater management plan will ensure that UBC’s commitment to environmental sustainability is maintained both during and after construction.

description: Three-dimensional data have become increasingly present in earth observation over the last decades. However, many 3D surveys are still underexploited due to the lack of accessible and explainable automatic classification methods, for example, new topo-bathymetric lidar data. In this work, we introduce explainable machine learning for 3D data classification using Multiple Attributes, Scales, and Clouds under 3DMASC, a new workflow. This workflow introduces multi-cloud classification through dual-cloud features, encrypting local spectral and geometrical ratios and differences. 3DMASC uses classical multi-scale descriptors adapted to all types of 3D point clouds and new ones based on their spatial variations. In this paper, we present the performances of 3DMASC for multi-class classification of topo-bathymetric lidar data in coastal and fluvial environments. We show how multivariate and embedded feature selection allows the building of optimized predictor sets of reduced complexity, and we identify features particularly relevant for coastal and riverine scene descriptions. Our results show the importance of dual-cloud features, lidar return-based attributes averaged over specific scales, and of statistics of dimensionality-based and spectral features. Additionally, they indicate that small to medium spherical neighbourhood diameters (<7 m) are sufficient to build effective classifiers, namely when combined with distance-to-ground or distance-to-water-surface features. Without using optional RGB information, and with a maximum of 37 descriptors, we obtain classification accuracies between 91 % for complex multi-class tasks and 98 % for lower-level processing using models trained on less than 2000 samples per class. Comparisons with classical point cloud classification methods show that 3DMASC features have a significantly improved descriptive power. Our contributions are made available through a plugin in the CloudCompare software, allowing non-specialist users to create classifiers for any type of 3D data characterized by 1 or 2 point clouds (airborne or terrestrial lidar, structure from motion), and two labelled topo-bathymetric lidar datasets, available on https://opentopography.org/.

description: A two -period efficiency wage model is constructed to show that granting tenure may be a rational choice by a firm. The driving force is the idea that tenure has value to the employee who receives it. Consequently the turnover cost of tenured employees is lower than that of untenured. The difference is the benefit the firm draws from granting tenure. The cost involves the firm's commitment to employ the tenured employees at the second period. The fraction of tenured employees in the firm's labor force is the variable whose optimal choice maximizes the present value of profits.

description: The properties of eta-nucleus interaction and their experimental consequences are investigated with eta-nucleus optical potentials obtained by postulating the N*(1535) dominance for eta-N system. The N*(1535) properties in nuclear medium are evaluated by two kinds of chiral effective models based on distinct pictures of N*(1535). We find that these two models provide qualitatively different optical potentials of the eta meson, reflecting the in-medium properties of N*(1535) in these models. In order to compare these models in physical observables, we calculate spectra of (d,3He) reactions for the eta mesic nucleus formation with various kinds of target nuclei. We show that the (d,3He) spectra obtained in these models are significantly different and are expected to be distinguishable in experiments.

description: We study the average shape of fluctuations for subdiffusive processes, i.e., processes with uncorrelated increments but where the waiting time distribution has a broad power-law tail. This shape is obtained analytically by means of a fractional diffusion approach. We find that, in contrast with processes where the waiting time between increments has finite variance, the fluctuation shape is no longer a semicircle: it tends to adopt a table-like form as the subdiffusive character of the process increases. The theoretical predictions are compared with numerical simulation results.

description: Porphyrins are cyclic tetrapyrazoles which are known to be selectively retained by neoplastic tissue in animals and humans. It has been demonstrated that chelation of a paramagnetic metal which can significantly increase the relaxation rate (1/T$\sb1)$ of water with a porphyrin may serve as potential contrast agents for tumors in Magnetic Resonance Imaging (MRI). Mn(III), Fe(II), and Gd(III) complexes of tetraphenyl (4-sulfonato) porphine (TPPS$\sb4)$ and other porphyrins were evaluated as potential MRI contrast agents. Based on consideration of relaxivity, solubility, stability, toxicity, uptake and distribution, MnTPPS$\sb4$ was determined to be the best model compound to provide insight into the question of selectivity in neoplastic tissue as well as determining its clinical utility as a MRI contrast agent. The question of neoplastic selectivity was pursued with normal and neoplastic human breast cell lines in vitro to quantitatively determine the differences in metalloporphyrin uptake. It was observed that the neoplastic breast cell line, MCF-7 WT, had a six-fold greater difference in uptake when compared to the normal human breast cell line, Hs 578 Bst. This result not only confirmed that there was enhanced uptake in a neoplastic cell line as compared to a normal (control) cell line, but that tissue culture results that involved uptake of metalloporphyrins could be used to adequately predict the uptake and plateau phases in vivo with the same implanted neoplastic cells. This is the first time that normal and neoplastic breast cell lines from similar in vivo loci have been used to compare the neoplastic selectivity of a metalloporphyrin in vitro. In vitro human cell models and in vivo murine animal models were utilized to determine the distribution and toxicity of the metalloporphyrin, MnTPPS$\sb4.$ Distribution studies indicated that the agent located primarily intracellularly in vitro and in viable tumor in vivo. Toxicity studies were conducted primarily to determine the IC$\sb{50}$ of the metalloporphyrin in vitro and the ID$\sb{50}$ of the metalloporphyrin in vivo, in order to determine the working range of the compound under both in vivo and in vitro conditions. The agent was injected into murine animal models bearing human colon and human breast carcinoma. It was shown that effective soft tissue contrast of neoplastic tissue by IP injected metalloporphyrin utilizing MRI, is observed at 24 hours and 48 hours respectively with contrast enhancement evident in the tumor for as long as eight days. In conclusion, paramagnetic metalloporphyrins may provide a useful clinical modality for the determination of neoplastic tissue by MRI if the dose to contrast ratio can be increased for safe clinical efficacy.

description: It is shown that the $\barΛ/Λ$ cross section ratio in semi-inclusive electroproduction of $Λ$ and $\barΛ$ hyperons in deep inelastic scattering of charged lepton on a nucleon target, can provide useful information on the quark to $Λ$ fragmentation functions. This ratio is calculated explicitly in a quark-diquark model, a pQCD based analysis, and an SU(3) symmetry model, with three different options for the contribution from the unfavored fragmentation functions. The $x$-dependence of this ratio is sensitive to the ratio of unfavored fragmentation functions over favored fragmentation functions, $D_{\bar{u}}^Λ(z)/D_{u}^Λ(z)$, whereas the $z$-dependence is sensitive to the flavor structure of the fragmentation functions, i.e., the ratio $D_u^Λ(z)/D_s^Λ(z)$. Future measurements by the HERMES Collaboration at DESY can discriminate between various cases.

We consider the Einstein-Born-Infeld solution and investigate critical points and stability. We also compare the results with the case of Einstein-Maxwell solutions. Besides, we find that thermal fluctuations, which appear as a logarithmic term in the entropy, affect the stability of the black hole and change the phase transition point. Moreover, we study the geometrical thermodynamics and find that the behaviour of the linear Maxwell solution is the same as the nonlinear one.

description: The primary purpose of this paper is to see how well a recently proposed new model fits (a) the position of the baryon acoustic oscillations (BAO) features observed in the large-scale distribution of galaxies and (b) the angular size measured for the sound horizon due to BAO imprinted in the cosmic microwave background (CMB) anisotropy. The new model is a hybrid model that combines the tired light (TL) theory with a variant of the $ΛCDM$ model in which the cosmological constant is replaced with a covarying coupling constants' (CCC) parameter $α$. This model, dubbed the CCC+TL model, can fit the supernovae type 1a Pantheon+ data as accurately as the $ΛCDM$ model, and also fit the angular size of cosmic dawn galaxies observed by the James Webb Space Telescope, which is in tension with the $ΛCDM$ model. The results we obtained are $151.0 (\pm5.1)$ Mpc for the absolute BAO scale at the current epoch, and the angular size of the sound horizon $θ_{sh}=0.60°$ matching Planck's observations at the surface of the last scattering when the baryon density is set to 100% of the matter density and |$α$| is increased by 5.6%. It remains to be seen if the new model is consistent with the CMB power spectrum, the big-bang nucleosynthesis of light elements, and other critical observations.

Character formation as a focus of seminary curricula

Publisher: name: American University

description: In response to the lack of research during the 1970's and 1980's on the status of seminary curriculum development, this study addresses these questions: Is character formation currently the focus of seminary curricula? To what extent is this the focus? How do such curricula reflect this focus?; This study grew out of an interest in whether or not the curricula of contemporary seminaries were shaped so that they effectively prepared church leadership, in light of the increasingly diverse student body, preparing to be clergy, and the current demands on the seminary which are generated by church needs and societal issues. After finding in the literature a dearth of research on curriculum development and a growing dialogue concerning its problems and possible solutions, this study focuses on character formation as one possible unifier of the curriculum and documents the existence of seminaries that focus on character formation in their curricula. Using a combination of mailed surveys, created for this study, and on-site observations and informal interviews, two types of populations were investigated in a two phase study. Phase One included all Protestant seminaries in the United States that are members of ATS (The Association of Theological Schools). Out of the fifty-three responding seminaries that claimed a curricular focus on character formation, three were selected for in-depth study in Phase Two. Two hypotheses were investigated: (1) there exist seminaries whose curricula have character formation as an intentional focus and that these seminaries comprise a cross-section of seminaries, as regards characteristics related to denominational affiliation, enrollment size, and regional geographic location and (2) among such curricula there are a variety of approaches to the process of character formation, which include activities within the formal program of study and non-required activities. The purpose was to validate the claim and to identify the curricula strategies that were character forming. After concluding that there exist seminaries with this focus, attention was given to describing the settings in which the curricula approach had taken shape and was implemented in order to provide models for other seminaries with interest in focusing on character formation.

description: "The unambiguous account of proper quantum phenomena must, in principle, include a description of all relevant features of experimental arrangement" (Bohr). The measurement process is composed of pre-measurement (quantum correlation of the system with the pointer variable), and an irreversible decoherence via interaction with an environment. The system ends up in a probabilistic mixture of the eigenstates of the measured observable. For the pre-measurement stage, any attempt to introduce an 'outcome' leads, as we show, to a logical contradiction, $1=i$. This nullifies claims that a modified concept of Wigner's Friend, who just pre-measures, can lead to valid results concerning quantum theory.

description: In recent years, there has been a growing interest in flatband systems which exhibit macroscopic degeneracies. These systems offer a valuable mathematical framework for the extreme sensitivity to perturbations and interactions. This sensitivity unveils a wide variety of exotic and unconventional physical phenomena. Moreover, the progress in their experimental realization contributes to the expanding landscape of exploration in this field. This thesis aims to summarize all the works throughout the Ph.D. program. Firstly, an in-depth exploration was conducted on the impact of weak quasiperiodic perturbations on one-dimensional two-band all-bands-flat lattices. These tight-binding Hamiltonian are diagonalized through a sequence of local unitary transformations. By adjusting the quasiperiodic potential parameters, the key achievement involves finding a critical-to-insulator transition and identifying fractality edges in the flatband systems with quasiperiodic perturbations. Next, the investigation delved into the effects of on-site interactions among hard-core bosons in one- and two-dimensional cross-stitch lattices. One key finding is that groundstate energy primarily depends on compact localized states. Moreover, the presence of barriers of compact localized states trap bosons, leading to the emergence of non-ergodic excitation and Hilbert space fragmentation. Lastly, a compact localized eigenstate of the one-dimensional diamond chain using an electric circuit was successfully generated via local (linear and non-linear) driving. This achievement opens up a versatile circuit platform for the generation of flatbands and holds promise for potential applications in the field of quantum information. I hope these collective efforts have expanded the frontiers of the field and made a meaningful contribution to the scientific community.

description: To study the interplay between global market choice and local peer pressure, we construct a minority-game-like econophysical model. In this so-called networked minority game model, every selfish player uses both the historical minority choice of the population and the historical choice of one's neighbors in an unbiased manner to make decision. Results of numerical simulation show that the level of cooperation in the networked minority game differs remarkably from the original minority game as well as the prediction of the crowd-anticrowd theory. We argue that the deviation from the crowd-anticrowd theory is due to the negligence of the effect of a four point correlation function in the effective Hamiltonian of the system.

description: In recent years there has been significant progress in time series anomaly detection. However, after detecting an (perhaps tentative) anomaly, can we explain it? Such explanations would be useful to triage anomalies. For example, in an oil refinery, should we respond to an anomaly by dispatching a hydraulic engineer, or an intern to replace the battery on a sensor? There have been some parallel efforts to explain anomalies, however many proposed techniques produce explanations that are indirect, and often seem more complex than the anomaly they seek to explain. Our review of the literature/checklists/user-manuals used by frontline practitioners in various domains reveals an interesting near-universal commonality. Most practitioners discuss, explain and report anomalies in the following format: The anomaly would be like normal data A, if not for the corruption B. The reader will appreciate that is a type of counterfactual explanation. In this work we introduce a domain agnostic counterfactual explanation technique to produce explanations for time series anomalies. As we will show, our method can produce both visual and text-based explanations that are objectively correct, intuitive and in many circumstances, directly actionable.

Character formation as a focus of seminary curricula

description: In response to the lack of research during the 1970's and 1980's on the status of seminary curriculum development, this study addresses these questions: Is character formation currently the focus of seminary curricula? To what extent is this the focus? How do such curricula reflect this focus?; This study grew out of an interest in whether or not the curricula of contemporary seminaries were shaped so that they effectively prepared church leadership, in light of the increasingly diverse student body, preparing to be clergy, and the current demands on the seminary which are generated by church needs and societal issues. After finding in the literature a dearth of research on curriculum development and a growing dialogue concerning its problems and possible solutions, this study focuses on character formation as one possible unifier of the curriculum and documents the existence of seminaries that focus on character formation in their curricula. Using a combination of mailed surveys, created for this study, and on-site observations and informal interviews, two types of populations were investigated in a two phase study. Phase One included all Protestant seminaries in the United States that are members of ATS (The Association of Theological Schools). Out of the fifty-three responding seminaries that claimed a curricular focus on character formation, three were selected for in-depth study in Phase Two. Two hypotheses were investigated: (1) there exist seminaries whose curricula have character formation as an intentional focus and that these seminaries comprise a cross-section of seminaries, as regards characteristics related to denominational affiliation, enrollment size, and regional geographic location and (2) among such curricula there are a variety of approaches to the process of character formation, which include activities within the formal program of study and non-required activities. The purpose was to validate the claim and to identify the curricula strategies that were character forming. After concluding that there exist seminaries with this focus, attention was given to describing the settings in which the curricula approach had taken shape and was implemented in order to provide models for other seminaries with interest in focusing on character formation.

description: Expensive ultrasonic anemometers are usually required to measure wind speed accurately. The aim of this work is to overcome the loss of accuracy of a low cost hot-wire anemometer caused by the changes of air temperature, by means of a probabilistic calibration using Gaussian Process Regression. Gaussian Process Regression is a non-parametric, Bayesian, and supervised learning method designed to make predictions of an unknown target variable as a function of one or more known input variables. Our approach is validated against real datasets, obtaining a good performance in inferring the actual wind speed values. By performing, before its real use in the field, a calibration of the hot-wire anemometer taking into account air temperature, permits that the wind speed can be estimated for the typical range of ambient temperatures, including a grounded uncertainty estimation for each speed measure.

description: We consider the corrections to deuterium hyperfine structure originating from the two-photon exchange between electron and deuteron, with the deuteron excitations in the intermediate states. In particular, the motion of the two intermediate nucleons as a whole is taken into account. The problem is solved in the zero-range approximation. The result is in good agreement with the experimental value of the deuterium hyperfine splitting.

Fulbright scholars as cultural mediators: An exploratory study
Creators: name: Snow, Nancy Elizabeth
Publisher: name: American University
Year: 2023

description: The main purpose of this study was to investigate the cultural mediator role of a group of Fulbright Program international graduate students studying in the United States and the anticipated cultural mediator role expected upon reentry into the home culture. The study, based on a communication and culture-learning model, was designed to test the impact that the following variables had upon the cultural mediator role: host contact conditions; host culture social relations (intimacy, multicultural networks); intercultural communication competence (host knowledge, home knowledge, second language proficiency, intercultural communication skills, cultural relativism); cultural identity (ingroup strength, outgroup orientation); and background variables (previous cross-cultural exposure, previous contact with Americans, and preacademic training). The study was conducted using a sample of 290 Fulbright international graduate students who participated in a Fulbright Intercultural Survey (FIS) designed by the author and implemented in the fall of 1991. Additional personal telephone interviews probed the mediator role through questions which allowed the Fulbright students to discuss culture-learning experiences in which they enhanced their understanding of Americans and American culture or Americans enhanced their understanding of them and their culture. The data supported several but not all of the hypotheses. Intimacy and multicultural networks, in this case with host nationals, were found to be the two most significant variables related to the outcome of cultural mediation in the home and host culture. In addition, knowledge of the home and host culture were related positively to outcomes of mediation. Some data supported a relationship for mediation only in certain settings. For instance, preacademic training and previous contact with Americans were positively correlated to anticipated mediation in the home culture exclusively. The author concludes that the Fulbright international graduate students are enacting mediation outcomes as part of their academic sojourns and that these outcomes complement the stated goal of mutual understanding described in the original Fulbright program legislation. However, the study is not readily able to predict what longterm effect these mediation outcomes might have upon the Fulbright scholars who return to their cultures of origin.
