Keeping Body and Soul Together: Inclusion, Contingency and Methodology in the College Writing Center
Creators: name: Gorham, Aja B
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: Writing centers have become commonplace on college campuses. Traditionally, writing centers were primarily staffed by undergraduate peer tutors, and writing center literature continues to focus on peer tutoring. More recently, these spaces are increasingly staffed by professional tutors, who have advanced degrees and often work in the writing center as part of adjunct teaching both of which are contingent on enrollment. The increase of professional tutors challenges assumptions in writing center literature about how tutors foster inclusion within the tutorial. Because professional tutors have a different working reality than peer tutors, it is important to examine how conventional tutoring methods enact inclusion. This research is interested in how contingent employment impacts professional tutors’ work and how they work with community college students across ability levels. Drawing from Disability Studies and the sociocultural process of creating bounds of inclusion, known as othering, this study uses qualitative methods to explore the relationship of student experience and the working conditions of eight professional tutors in a community college writing center. Using interview data, this dissertation examines the following questions: (1) How do professional tutors experience contingency in relation to their work in a community college writing center? (2) How do professional tutors perceive students who have been assigned to remedial courses preceding first year composition? (3)How are professional tutors trained to work with students with a broad range of abilities? (4) How do professional tutors replicate and/or challenge ideals of normalcy? This study specifically seeks to examine how tutors’ working conditions may influence their work with students across ability levels. Finally, this study reflects on these professional tutors’ experiences to discuss implications for future research and labor practices regarding professional tutors in the collegiate writing center.

description: We calculate heating rate, attractive conservative and tangential dissipative fluctuation electromagnetic forces felt by a thick plate moving with nonrelativistic velocity parallel to a closely spaced another plate in rest using relativistic fluctuation electrodynamics. We argue that recently developed relativistic out of equilibrium theory of fluctuation electromagnetic interactions (Volokitin et. al., Phys.Rev. B78, 155437 (2008))has serious drawbacks.

description: We investigate the phase diagrams of RMn$_2$O$_5$ via a first-principles effective-Hamiltonian method. We are able to reproduce the most important features of the complicated magnetic and ferroelectric phase transitions. The calculated polarization as a function of temperature agrees very well with experiments. The dielectric-constant step at the commensurate-to -incommensurate magnetic phase transition is well reproduced. The microscopic mechanisms for the phase transitions are discussed.
On the Completeness of Reflex Astrometry on Extrasolar Planets near the Sensitivity Limit
Creators: name: Brown, Robert A.

Year: 2009
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: We provide a preliminary estimate of the performance of reflex astrometry on Earth-like planets in the habitable zones of nearby stars. In Monte Carlo experiments, we analyze large samples of astrometric data sets with low to moderate signal-to-noise ratios. We treat the idealized case of a single planet orbiting a single star, and assume there are no non-Keplerian complications or uncertainties. The real case can only be more difficult. We use periodograms for discovery and least-squares fits for estimating the Keplerian parameters. We find a completeness for detection compatible with estimates in the literature. We find mass estimation by least squares to be biased, as has been found for noisy radial-velocity data sets; this bias degrades the completeness of accurate mass estimation. When we compare the true planetary position with the position predicted from the fitted orbital parameters, at future times, we find low completeness for an accuracy goal of 0.3 times the semimajor axis of the planet, even with no delay following the end of astrometric observations. Our findings suggest that the recommendation of the ExoPlanet Task Force (Lunine et al. 2008) for "the capability to measure convincingly wobble semi-amplitudes down to 0.2 $μ$as integrated over the mission lifetime," may not be satisfied by an instrument characterized by the noise floor of the Space Interferometry Mission, $σ_\mathrm{floor}\approx0.035μ$as. An important, unsolved, strategic challenge for the exoplanetary science program is figuring out how to predict the future position of an Earth-like planet with accuracy sufficient to ensure the efficiency and success of the science operations for follow-on spectroscopy, which would search for biologically significant molecules in the atmosphere.

Subjects: Uncategorized

description: College students demonstrate high rates of depression, anxiety and alcohol consumption. Neuroticism consistently predicts onset of psychiatric symptoms; however, our understanding of malleable risk characteristics that mediate associations between neuroticism and psychiatric symptoms is limited. The current study aimed to investigate whether anxiety sensitivity (AS) and/or distress tolerance (DT) mediated relationships between neuroticism and psychiatric symptoms (anxiety, depression, and alcohol use) in a high-risk sample of college students. Participants were 316 college students (75.9% women) with a history of interpersonal trauma exposure and current alcohol use who were participating in a university-wide longitudinal study of emotional health. Participants completed measures assessing personality, AS, DT, and psychiatric symptoms (including depression, anxiety, and alcohol consumption) over four time points spanning an average of 26 months. Results of structural equation modeling demonstrated that DT, but not AS, mediated relationships between neuroticism and depression, as well as neuroticism and anxiety. Neither DT nor AS mediated the relationship between neuroticism and alcohol consumption. These findings contribute to our understanding of the development of depression and anxiety in trauma-exposed college students with elevated trait neuroticism.

description: The discovery of a Higgs particle is possible in a variety of search channels at the LHC. However the true identity of any putative Higgs boson will at first remain ambiguous, until one has experimentally excluded other possible assignments of quantum numbers and couplings. We quantify to what degree one can discriminate a Standard Model Higgs boson from "look-alikes" at, or close to, the moment of discovery at the LHC. We focus on the fully-reconstructible "golden" decay mode to a pair of Z bosons and a four-lepton final state, simulating sPlot-weighted samples of signal and background events. Considering both on-shell and off-shell Z's, we show how to utilize the full decay information from the events, including the distributions and correlations of the five relevant angular variables. We demonstrate how the finite phase space acceptance of any LHC detector sculpts the decay distributions, a feature neglected in previous studies. We use likelihood ratios to discriminate a Standard Model Higgs from look-alikes with other spins or nonstandard parity, CP, or form factors. For a benchmark resonance mass of 200 GeV/c^2, we achieve a median expected discrimination significance of 3 sigma with as few as 19 events, and even better discrimination for the off-shell decays of a 145 GeV/c^2 resonance.

Re-Conceptualizing Safety: Examining the Intersections of Patriarchal Violence and Survivors' Empowerment

Year: 2021
Subjects: Uncategorized

description: This study contributes to literature on gender-based violence, help-seeking, legal cynicism, betrayal trauma, and empowerment using a sequential mixed method design. Beginning with a web-based survey (n = 170) followed by in-depth interviews with purposefully selected participants (n = 10), the study empirically examined and explored how individual, interpersonal, community, institutional, and policy factors influence gender-oppressed Black people’s exposure to state violence, their safety responses to violence, and their sense of empowerment as it relates to safety. The study also explored how participants conceptualize safety. The quantitative findings suggested that individual factors such as gender identity, sexual orientation, migration status, caregiver status, disability, and arrest history were associated with higher rates of state violence exposure. Furthermore, interpersonal factors such as violence in both intimate and community contexts, as well as help-seeking from formal and legal sources, were associated with higher rates of state violence exposure. Higher levels of safety-related empowerment were associated with institutional trust while lower levels of safety-related empowerment were associated with police violence. The qualitative findings found overlapping core themes of hypersurveillance, controlling narratives, system rigidity, carceral collusion, and provider incompetence associated with state violence exposure. Participants’ narratives revealed that the individual, interpersonal, and structural factors within these themes also have disempowering effects on their sense of safety. However, participants also found strength in their traumas and sources of empowerment through cultivated community. The notion of shared precariousness in collective identity spurred a politic of collective care. The study identified anger from institutional harm as a primary driver to participants’ struggles for institutional transformation. While participants had variant understandings of safety, they all expressed elements of physical/material, relational, and emotional safety. Lastly, participants envisioned a range of practices, systems and other resources needed for Black women, trans, and gender nonconforming people to be safe. These findings provide insight into the causes and consequences of state violence among Black women, trans, and gender nonconforming people and have critical implications for future research, social work practice, policy, and education.

Dentre muitas tendências quanto ao futuro das cidades há uma, voltada especialmente para o bem-estar urbano-educativo das crianças que, devido seu crescimento exponencial nos últimos anos, talvez esteja mais próxima de um sintoma que de uma resposta. São tantos os acordos, políticas, prêmios, organizações, fóruns e publicações a respeito de uma questão que em muitos de seus aspectos não encontrará solução razoável, que somos levados a analisar tal “coelho de Alice” da vez. Ao mesmo tempo, a emergência de algoritmos generativos transformadores que, segundo seus entusiastas, são capazes de aprender e criar mundos “da mesma forma que uma criança”, indicam mudanças em uma profunda convergência há muito tempo conhecida, embora aparentemente esquecida, entre a inteligência das cidades e as citadelas da memória. Nesse sentido, apresentamos um estudo exploratório, baseado em alguns experimentos acadêmicos, a partir dos quais perguntamos sobre o verdadeiro papel da nova onda das ditas “cidades educadoras”.

description: Previous studies indicated that intrinsic point defects play a crucial role for the density of states of ferromagnetic half-metals in the band gap region: At large concentrations, defect-derived bands might close the gap at the Fermi energy in the minority spin channel. In this work, structural disorder in the Co- and Mn-sublattices of the full Heusler alloy Co_2-xMn_1+xSi (-1 < x < 2) is investigated with a cluster expansion approach, parametrized using all-electron density functional theory calculations. By establishing two separate cluster expansions, one for the formation energy and one for the total spin moment, we are in position to determine the stability of different configurations, to predict new (also half-metallic) ground states and to extend the known Slater-Pauling rule for ideally stoichiometric Heusler alloys to non-stoichiometric, Mn-rich compositions. This enables us to identify potentially half-metallic structures in the Mn-rich region. With the help of Monte Carlo simulations based on the cluster expansion, we establish theoretically that Co_2-xMn_1+xSi close to the stoichiometric composition ought to show a high degree of structural order in thermodynamic equilibrium. Hence, samples prepared with the correct stoichiometry should indeed be half-metallic after thermal annealing. Moreover, we predict that adding a small amount of Mn to stoichiometric Co_2MnSi allows to suppress the thermally activated formation of detrimental Co antisites. At Mn-rich compositions (x>1), the ordered ground state structures predicted for zero temperature are found to be thermally unstable and to decompose into Co2MnSi and Mn3Si above room temperature.

description: Mean-field methods are a very powerful tool for investigating weakly interacting many-body systems in many branches of physics. In particular, they describe with excellent accuracy trapped Bose-Einstein condensates. A generic, but difficult question concerns the relation between the symmetry properties of the true many-body state and its mean-field approximation. Here, we address this question by considering, theoretically, vortex nucleation in a rotating Bose-Einstein condensate. A slow sweep of the rotation frequency changes the state of the system from being at rest to the one containing one vortex. Within the mean-field framework, the jump in symmetry occurs through a turbulent phase around a certain critical frequency. The exact many-body ground state at the critical frequency exhibits strong correlations and entanglement. We believe that this constitutes a paradigm example of symmetry breaking in - or change of the order parameter of - quantum many-body systems in the course of adiabatic evolution.

Sperm Hunter - Neural Network Model for Sperm Identification in Azoospermic Males

description: Azoospermia is defined as a lack of sperm in the ejaculate and causes infertility in 1% of men worldwide. For 60% of these men, the lack of sperm is caused by spermatogenic dysfunction (ASD) where the testis is unable to produce sperm as opposed to a blockage in the ejaculatory pathway. Microdissection testicular sperm extraction (MicroTESE) is the recommended treatment to extract sperm directly from the testis for use in IVF, however, the surgery is not as accurate as it can be, and every failure costs a potential human life. A novice surgeon, prior to their first 50 procedures, will have a 12% lower sperm retrieval rate and will perform the procedure 25 minutes slower than an expert surgeon. The learning curve for the procedure continues to be steep as even an expert surgeon will reach 50% average sperm retrieval only after 250 procedures. To address this problem, we created a rodent model of ASD using the spermatotoxic chemotherapy agent busulfan. A neural network was trained on images taken during the MicroTESE procedure on ASD rats and sperm counts associated with the sampling locations to develop a model to detect sperm-dense locations. The resulting model achieved sperm prediction rates comparable to fellowship-trained surgeons when evaluated by an operator with moderate medical training and no prior experience with the MicroTESE procedure. Once validated in human studies, this model has the potential to augment sperm retrieval rates and deliver reproducible results during MicroTESE procedures.

description: Due to increasing concerns about the ever increasing energy demand, the
 global energy system needs to transition away from fossil fuels, as they
 have been one of the main causes for climate change and air pollution.
 Fuel cells offer a good alternative to conventional thermal devices, as
 they usually use hydrogen and oxygen to produce electricity without
 greenhouse gases emissions. One of the main drawbacks to fuel cell
 commercialisation is the use of expensive catalysts, such as platinum, and
 their long-term stability under operation. Therefore, the design and study
 of cheap and durable catalysts is required to push the development of fuel
 cells. MXenes, a new family of two-dimensional transition metal carbides
 and nitrides materials, have shown some potential as support for ORR
 catalysts. However, the performance of electrocatalysts is directly
 related to the available surface where the electrochemical reaction could
 take place, and MXenes have pretty low specific surface areas compared to
 conventional supports used in the field of catalysis.

 This thesis reports the development of a synthesis method focused on
 improving the final catalyst surface area using MXene (Ti3C2) as support,
 by intercalating the precursors between the MXene layers before annealing.
 This is shown to lead to the formation of porous MXene structures, with
 increased surface area and decomposition products from the precursors on
 the surface of the MXene layers, which hindered the MXene layer restacking
 during thermal treatment. The samples where then tested in a
 three-electrode setup using the RDE method to evaluate the ORR performance
 of the synthesized materials. It was found that the addition of the
 precursors improved the overall performance of the materials. The
 different samples were also characterized to understand the connection
 between physico-chemical properties and electrochemical properties.

description: We have investigated the influence of different non-linear relativistic mean field models ($NL$, $NLρ$ and $NLρδ$) on spallation neutrons for p+Fe and Pb reactions at 0.8, 1.2 and 1.6 GeV by means of a relativistic Boltzmann Uehling Uhlenbeck (RBUU) approach plus a statistical multifragmentation (SM) decay model. We find that the "evaporation shoulder", i.e. the neutron energy spectrum from 3 to 30 MeV, almost for any emission angle is quite sensitive to the isospin part of the mean field. For the more neutron-rich Pb-target the evaporation component can be directly related to the low density behavior on the symmetry energy in the thermal expansion phase of the excited compound system. It turns out that the spallation data for the reactions under study are shown to be more consistent with RBUU+SM employing the $NLρ$ effective lagrangian.

description: Data exploration stands to benefit from environments that permit users to examine and juxtapose many views of data, particularly views that present diverse selections of data values and attributes. Large, high-resolution environments are capable of showing many related views of data, but efficiently creating and displaying visualizations in these environments presents significant challenges. In this dissertation, I will present my research on “multi-view data exploration interactions” that enable users to create sets of views with coherent data value and attribute variations, through multi-modal speech and mid-air pointing gestures in large display environments. This work enables users to rapidly and efficiently generate sets of views in support of multi-view data exploration tasks, organize these views in coherent collections, and operate on sets of views collectively, rather than individually, to efficiently reach large portions of the ’data and attribute space’. I will present three contributions: 1) an observational study of data exploration in a large display environment with speech and mid-air gestures, 2) ’Traverse’, an interaction technique for data exploration, based on this study, which uses natural language to create and pivot sets of views, and 3) ’Ditto’, a multi-modal speech and mid-air pointing gesture interactive environment, which utilizes the multi-view data exploration technique, in large display environments.

description: Motivated by streaming applications with stringent delay constraints, we consider the design of online network coding algorithms with timely delivery guarantees. Assuming that the sender is providing the same data to multiple receivers over independent packet erasure channels, we focus on the case of perfect feedback and heterogeneous erasure probabilities. Based on a general analytical framework for evaluating the decoding delay, we show that existing ARQ schemes fail to ensure that receivers with weak channels are able to recover from packet losses within reasonable time. To overcome this problem, we re-define the encoding rules in order to break the chains of linear combinations that cannot be decoded after one of the packets is lost. Our results show that sending uncoded packets at key times ensures that all the receivers are able to meet specific delay requirements with very high probability.

description: Purpose: To identify associations between the effect of family chaos on dental appointment compliance in a pediatric dental population. Method: Caregivers of children presenting to the UIC pediatric dental clinic were invited to participate in this study. Recruited caregivers were asked screening questions to verify inclusion and exclusion criteria. After the survey was completed, patient’s dmft, follow-up appointment date, and follow-up appointment compliance was recorded. Results: Seventy-four participants were eligible for the study. Seventy-one percent of families lived within Cook County. The average family had a mean of 3 adults and a mean of 3 children living in the home. Fifty-four percent of the children were between the ages of 3-6, 38% were between ages of 7-10, and 8% were between ages of 11-15. Thirty-four percent children were Caucasian, 26% were African American, 4% were Asian, 5% were Native American Indian and 15% were multiracial. 53% children were Hispanic. Eighty-two percent of patients showed up to their appointments; 18% were late over 15 minutes or failed their appointments. Thirty-one percent of patients had CHAOS scores of under 40 and 62% of patients had scores between 41-60. The average CHAOS score was 45.85. P-value of 0.143 was calculated for a t-test to see if there was a significant difference in CHAOS scores with patients who showed to their appointments versus patients who did not show. Conclusion: There was no difference in CHAOS scores with patients who showed for their appointments and patients who did not show or were 15 minutes late.

description: Using the tomographic probability representation of qudit states and the inverse spin-portrait method, we suggest a bijective map of the qudit density operator onto a single probability distribution. Within the framework of the approach proposed, any quantum spin-j state is associated with the (2j+1)(4j+1)-dimensional probability vector whose components are labeled by spin projections and points on the sphere. Such a vector has a clear physical meaning and can be relatively easily measured. Quantum states form a convex subset of the 2j(4j+3) simplex, with the boundary being illustrated for qubits (j=1/2) and qutrits (j=1). A relation to the (2j+1)^2- and (2j+1)(2j+2)-dimensional probability vectors is established in terms of spin-s portraits. We also address an auxiliary problem of the optimum reconstruction of qudit states, where the optimality implies a minimum relative error of the density matrix due to the errors in measured probabilities.

description: The final explosive fate of massive stars, and the nature of the compact remnants they leave behind (black holes and neutron stars), are major open questions in astrophysics. Many massive stars are stripped of their outer hydrogen envelopes as they evolve. Such Wolf-Rayet (W-R) stars emit strong and rapidly expanding (v_wind>1000 km/s) winds indicating a high escape velocity from the stellar surface. A fraction of this population is also helium depleted, with spectra dominated by highly-ionized emission lines of carbon and oxygen (Types WC/WO). Evidence indicates that the most commonly-observed supernova (SN) explosions that lack hydrogen and helium (Types Ib/Ic) cannot result from massive WC/WO stars, leading some to suggest that most such stars collapse directly into black holes without a visible supernova explosions. Here, we present observations of supernova SN 2019hgp, discovered about a day after explosion. The short rise time and rapid decline place it among an emerging population of rapidly-evolving transients (RETs). Spectroscopy reveals a rich set of emission lines indicating that the explosion occurred within a nebula composed of carbon, oxygen, and neon. Narrow absorption features show that this material is expanding at relatively high velocities (>1500 km/s) requiring a compact progenitor. Our observations are consistent with an explosion of a massive WC/WO star, and suggest that massive W-R stars may be the progenitors of some rapidly evolving transients.

description: It is acknowledged that the most common cause of dementia worldwide is Alzheimer's disease (AD). This condition progresses in severity from mild to severe and interferes with people's everyday routines. Early diagnosis plays a critical role in patient care and clinical trials. Convolutional neural networks (CNN) are used to create a framework for identifying specific disease features from MRI scans Classification of dementia involves approaches such as medical history review, neuropsychological tests, and magnetic resonance imaging (MRI). However, the image dataset obtained from Kaggle faces a significant issue of class imbalance, which requires equal distribution of samples from each class to address. In this article, to address this imbalance, the Synthetic Minority Oversampling Technique (SMOTE) is utilized. Furthermore, a pre-trained convolutional neural network has been applied to the DEMNET dementia network to extract key features from AD images. The proposed model achieved an impressive accuracy of 98.67%.

description: We present evidence on the role of the social environment for the development of gender differ- ences in competitiveness and earnings expectations. First, we document that the gender gap in competitiveness and earnings expectations is more pronounced among adolescents with low socioeconomic status (SES). We further document that there is a positive association between the competitiveness of mothers and their daughters, but not between the competitiveness of mothers and their sons. Second, we show that a randomized mentoring intervention that exposes low-SES children to predominantly female role models causally affects girls' willing- ness to compete and narrows both the gender gap in competitiveness as well as the gender gap in earnings expectations. Together, the results highlight the importance of the social environment in shaping willingness to compete and earnings expectations at a young age.

description: A mechanism by which animals cope with seasonal changes is by moving up to thousands of kilometers every year. These seasonal migrations require navigational, morphological and physiological adaptations for journeys to be successfully accomplished at the correct time and direction, in an energetically efficient manner. Migratory behavior contrasts with a year-round resident strategy in which animals adapt to climate swings in temperate environments, or to the challenges of breeding in the tropics (such as nest parasites and high nest predation rates). Among birds, migratory species are often closely related to year-round residents, implying migration is frequently gained and/or lost. In theory, these switches in migratory strategies may result in the formation of new species. I empirically tested this hypothesis, showing that loss of migration promoted speciation in flycatchers that have both migratory and year-round resident populations. I found evidence that loss of migration in Fork-tailed Flycatchers (Tyrannus savana) induced shifts in breeding schedules, which coupled with geographic isolation of breeding populations has led to the evolution of premating isolation and correlated evolution of morphology (i.e., in wing shape and tail length). Moreover, loss of migration has influenced conspecific communication of non-vocal acoustic signals produced by males with wing feathers; morphological evolution likely associated with flight efficiency has significantly changed the frequency at which wing feathers flutter. Finally, morphological evolution associated with migratory behavior has also led to differences in early stages of the life cycle, particularly in egg shape. These trends follow patterns observed at higher taxonomic levels, in which eggs from birds with longer wings tend to have more elliptical eggs, supporting the hypothesis that flight may impose constraints to egg shape. In conclusion, correlated evolution associated with losing migration in Fork-tailed Flycatchers has driven differentiation across multiple traits, enhancing the speciation process.

description: Hyperparameters are a critical factor in reliably training well-performing reinforcement learning (RL) agents. Unfortunately, developing and evaluating automated approaches for tuning such hyperparameters is both costly and time-consuming. As a result, such approaches are often only evaluated on a single domain or algorithm, making comparisons difficult and limiting insights into their generalizability. We propose ARLBench, a benchmark for hyperparameter optimization (HPO) in RL that allows comparisons of diverse HPO approaches while being highly efficient in evaluation. To enable research into HPO in RL, even in settings with low compute resources, we select a representative subset of HPO tasks spanning a variety of algorithm and environment combinations. This selection allows for generating a performance profile of an automated RL (AutoRL) method using only a fraction of the compute previously necessary, enabling a broader range of researchers to work on HPO in RL. With the extensive and large-scale dataset on hyperparameter landscapes that our selection is based on, ARLBench is an efficient, flexible, and future-oriented foundation for research on AutoRL. Both the benchmark and the dataset are available at https://github.com/automl/arlbench.

Energy measurement of pion beams

description: Pion energies between 30 MeV and 60 MeV have been determined by three methods: magnetic field, range and time of flight. The pion energy was measured to an accuracy 2 # by range and 5 % by the time of flight, and the three methods were consistant with one another. The pions which were used were produced by 500 MeV protons from the TRIUMF cyclotron. The pions were focussed into a beam using the M9 (or stopped π/μ) channel. The bending magnets of this channel define the momentum of the beam particles and thus give one method of determining the pion energy. Differential and integral range curves for aluminum and copper were taken and the differential curves were used to determine the range. In taking the differential curve the effect of stopping plates was examined. In the time of flight method, the leading edge; type discriminator was; found to give; a time walk, due to the different energy-loss; of particles in the plastic scintillator. This has a serious effect in determining the pion energies. However, the constant fraction discriminator was found to give dependable results and the measured energies agreed reasonably well with those of the other methods.

description: “Suspension of judgment” is an ambiguous term that may refer either to a doxastic state (“suspended judgment”) or to a doxastic action (“suspending judgment”). Based on a simple non-belief account, this paper presents a formal study of both aspects of suspension. We first introduce the notion of a suspension set (a set of non-beliefs) and determine its logical structure. Then we present the classical AGM operations of belief revision and belief contraction and give characterizations of them that refer to suspension sets rather than belief sets. Finally, we study the suspension operation, a
symmetric cousin of belief contraction, and characterize it both in terms of belief sets and in terms of suspension sets. Belief contraction and belief suspension thereby get reinterpreted as two different forms of the expansion of suspension sets. The project is interesting because in contrast to belief revision and belief contraction, the suspension operation is symmetric with respect to negation: suspending judgment on A is the same as suspending judgment on ¬A. Most of our results are premised on an assumption
of modesty: For every person with consistent beliefs, there is always at least one proposition on which she suspends judgment.

description: Carrier and thermal transport in semiconductors – both important parameters for the operation of electronic and optoelectronic devices – are primarily dependent on the thermal conductivity of the crystal lattice. Dominant anharmonic coupling processes, such as electron-phonon and phonon-phonon coupling, provide helpful insights into the thermal characteristics of wide bandgap semiconductors. Investigation on phonon coupling mechanisms will expand our understanding of their effects on electron transport and thermal conductivity of semiconductor devices, whereby mitigate the associated device problems and finally improve the performance of electronic and optoelectronic devices. More specifically, in high electron mobility transistors (HEMTs), the fast emission of longitudinal optical (LO) phonons can result in the formation of hot spots near the gate region where high electric fields produce hot electrons. In this thesis, we investigate the probability of phonon emission as a function of electron energy for confined and interface phonon modes for different wurtzite heterostructures. Novel phonon engineering concepts are introduced which facilitate thermal management through the production of polar optical phonons and acoustic phonons. This work offers a wide range of theoretical modeling and experimental studies of the carrier and thermal transport dynamics in structures including those in GaN- and AlN-based devices.
