description: In the past decade, scholars and the public have increasingly paid attention to queer populations and their experiences in the workforce. Yet, little work has been done to understand the meaning that queer men attribute to their sexuality in shaping their career decisions and experiences, leaving unanswered how and under what conditions sexuality consequentially influences queer men’s career decisions and experiences. Using data from 67 in-depth interviews with college-educated queer men living and working in the New York City Metropolitan Area, this dissertation examines how queer men make sense of their career-related decisions, attempts at securing employment, and their experiences once in the workforce as well as what role they believe their sexuality played in shaping these decisions and experiences. The central argument of this project is that the role that respondents believe their sexuality played in influencing career decisions and continues to play in shaping their experiences in the workforce is largely dependent on the perceived boundary brightness, or symbolic significance, surrounding or attributed to their sexuality; additionally, an individual’s boundary brightness is subject to change across stages in one’s career narrative. This boundary brightness was shaped by both how meaningful and consequential respondents believed their sexuality to be during a given career stage and how central their sexuality was to their self-conception. I break respondents into 4 groups based on boundary brightness across the three stages in their career narratives (career-related decisions, the labor market, and the workforce). The first is the Consistently Bright group—for whom sexuality meaningfully influenced their career decisions, experiences on the labor market, and how they navigated the workforce. The second group, the Dimmed Boundaries group, believed that their sexuality shaped their career decisions but not as something that they had to manage on the labor market or in the workforce. The third group, the Brightened Boundaries group, did not see their sexuality as something that shaped their career-related decisions but as something that shaped their experiences either on the labor market or in the workforce. Lastly, those in the Never Bright group did not perceive their sexuality as meaningfully shaping their decisions or experiences at any stage of their career narratives. Further, these findings highlight both the centrality of masculinity in queer men’s career narratives and the inadequacy of a categorical approach in examinations of sexuality and the sphere of work. I conclude by discussing what these findings can contribute to scholarly and public understandings of (sexual) identity and work and highlight potential avenues for future research.

description: The first experimental data from single-particle scattering experiments from free electron lasers (FELs) are now becoming available. The first such experiments are being performed on relatively large objects such as viruses, which produce relatively low-resolution, low-noise diffraction patterns in so-called "diffract-and-destroy" experiments. We describe a very simple test on the angular correlations of measured diffraction data to determine if the scattering is from an icosahedral particle. If this is confirmed, the efficient algorithm proposed can then combine diffraction data from multiple shots of particles in random unknown orientations to generate a full 3D image of the icosahedral particle. We demonstrate this with a simulation for the satellite tobacco necrosis virus (STNV), the atomic coordinates of whose asymmetric unit is given in Protein Data Bank entry 2BUK.

Attention Deficit Hyperactivity Disorder & Narrative Comprehension Deficits in College Students

Subjects: subject: Developmental Psychology

description: The current study examined if the narrative comprehension deficits that children with ADHD exhibit during childhood and adolescence continue in college students as a function of ADHD symptoms, and if a relationship existed between ADHD symptoms and self-efficacy. Children and adolescence with ADHD have difficulties in several areas of narrative comprehension, including maintaining goal structure, distinguishing important events from unimportant events, and making causal connections. If these deficits persist there also may be a relationship between ADHD symptoms and self-efficacy.  Higher levels of ADHD symptomatology were associated with difficulties recalling story events in the college population. Some findings differed from the patterns observed for children and adolescents. College students with higher symptoms of ADHD recalled fewer events in the Growing Pains recall. However, unlike children and adolescents, college students with higher symptoms of ADHD did not recall fewer of the Growing Pains important events or causally connected events. The pattern of findings for the fables is consistent with that seen in research studying children with symptoms of ADHD. These deficits may lead to a serious deficit in academic outcomes within this population.

description: Background: Passive immunization against SARS-CoV-2 limits viral burden and death from COVID-19; however, it poses a theoretical risk of disease exacerbation through antibody-dependent enhancement (ADE). ADE after anti-SARS-CoV2 antibody treatment has not been reported, and therefore the potential risk and promoting factors remain unknown. Case presentation: A 75-year-old female was admitted to the emergency room with recurrent, unexplained bruises and leukocytopenia, anemia, and thrombocytopenia. Evaluation of a bone marrow biopsy established the diagnosis of an acute promyelocytic leukemia (APL). SARS-CoV-2 RT-PCR testing of nasal and throat swabs on admission was negative. During the routine SARS-CoV-2 testing of inpatients, our patient tested positive for SARS-CoV-2 on day 14 after admission without typical COVID-19 symptoms. Due to disease- and therapy-related immunosuppression and advanced age conferring a high risk of progressing to severe COVID-19, casirivimab and imdevimab were administered as a preemptive approach. The patient developed immune activation and cytokine release syndrome (CRS) occurring within four hours of preemptive anti-SARS-CoV2 antibody (casirivimab/imdevimab) infusion. Immune activation and CRS were evidenced by a rapid increase in serum cytokines (IL-6, TNF alpha, IL-8, IL-10), acute respiratory insufficiency, and progressive acute respiratory distress syndrome. Discussion and conclusion: The temporal relationship between therapeutic antibody administration and the rapid laboratory, radiological, and clinical deterioration suggests that CRS was an antibody-related adverse event, potentially exacerbated by APL treatment-mediated differentiation of leukemic blasts and promyelocytes. This case highlights the need for careful assessment of life-threatening adverse events after passive SARS-CoV-2 immunization, especially in the clinical context of patients with complex immune and hematological landscapes.

description: We present the current controlled motion of dynamic soliton embedded in spin wave background in ferromagnetic nanowire. With the stronger breather character we get the novel magnetic rogue wave and clarify its formation mechanism. The generation of magnetic rogue wave is mainly arose from the accumulation of energy and magnons toward to its central part. We also observe that the spin-polarized current can control the exchange rate of magnons between envelope soliton and background, and the critical current condition is obtained analytically. Even more interesting is that the spin-transfer torque plays the completely opposite role for the cases of below and above the critical value.

Subjects: subject: Agricultural Education
subject: Curriculum and Social Inquiry

description: Research indicates that Kentucky agricultural educators are overworked and experience job related stress. Balancing work and home can be a struggle and stress induces burnout and teacher attrition. Shortages in the agriculture classroom could result in loss of agricultural education programs and negatively affect the profession. The purpose of this study was to 1) describe the demographics of Kentucky high school agricultural educators; 2) describe the work and home life balance for Kentucky agricultural educators; 3) determine the level of job satisfaction among Kentucky agricultural educators; 4) determine the perceived busiest time of the school year for Kentucky agricultural educators. The study was conducted on a census of the 2015-2016 Kentucky agriculture teacher directory and the survey was distributed online. Results indicate that agricultural educators work 52 hours per week, can balance work and home responsibilities with assistance from spouse/partner and experience job related stress on a regular basis. It was concluded that Kentucky agricultural teachers are satisfied with their job, but stressed about meeting the needs of work and family balance based on barriers including FFA activities, nightly meetings, childcare and time with spouse/partner.

description: Examinations of total viable counts (TVCs) and Salmonella spp. on the skin of individual pigs during the slaughter process are useful to identify abattoir-specific risk factors for (cross-)contamination. At seven process stages (lairage to before chilling), pigs were bacteriologically investigated by repeatedly sampling the same animals using the agar contact method. The mean TVC of all pigs increased significantly at the first three tested process stages (mean count, after delivery: 5.70 log cfu/cm2, after showering: 6.27 log cfu/cm2, after stunning: 6.48 log cfu/cm2). Significant mean TVC reductions occurred after scalding/dehairing (mean count: 3.71 log cfu/cm2), after singeing/flaming (2.70 log cfu/cm2), and after evisceration (2.44 log cfu/cm2) compared with the respective preceding process stages. At the end of the slaughter line and before chilling, the mean TVC was 2.33 log cfu/cm2, showing that the slaughter process reduced contamination significantly. The slaughter process effectively reduced even very high levels of incoming TVCs, since at the individual animal level, at the end of the slaughter process, there was no difference in the TVCs of animals with initially high and initially low TVCs. Additionally, 12 Salmonella spp. isolates were recovered from 12 different pigs, but only until the stage after scalding/dehairing. Overall, the agar contact method used is valuable for detecting hygiene deficiencies at slaughter, and is animal-equitable, practical, and suitable for use on live animals.
Towards an Understanding of the Role of Cation Packaging on DNA Protection from Oxidative Damage
Creators: name: Gay, Cody E.
Publisher: name: University of Kentucky
Year: 2016
Subjects: subject: Chemistry

description: In sperm chromatin, DNA exists in a highly condensed state reaching a final volume roughly twenty times that of a somatic nucleus. For the vast majority (>90%) of sperm DNA in mammals, somatic-like histones are first replaced by transition proteins which in turn are replaced by arginine-rich protamines. This near crystalline organization of the DNA in mature sperm is thought crucial for both the transport and protection of genetic information since all DNA repair mechanisms are shut down. Recent studies show that increased DNA damage is linked to dysfunctions in replacing histones with protamines resulting in mispackaged DNA. This increased DNA damage correlates not only to infertility but also impacts normal embryonic development. This damage is currently poorly characterized, but is known to involve oxidative base damage by reactive oxygen species (ROS).  Using a variety of biophysical methods, the effect of DNA condensation by polycations on the on free radical access and DNA damage in the packaged state was investigated. In Chapter 2, gel electrophoresis was used to quantify the ability of free radicals to damage both unpackaged and packaged DNA. DNA condensed by polycations shows significantly reduced levels of indirect damage from exposure to free radicals. Combining previous work on packaging density, it is also shown that differences in the packaged state, even by a few Angstroms, can result in significantly different degrees of damage to the DNA. In Chapter 3, we investigate the effects of protamine concentration on the ability to condense and protect DNA. Insufficient protamination is known to be a potential source of protamine dysfunction in mammalian sperm chromatin. Using gel retardation assays and UV-Vis studies, we examined the ability for DNA to condense with protamine at varying nitrogen to phosphate (N:P) charge ratios. Initial results on damage as a function of N:P are also discussed. Future work will more quantitatively determine the interrelationship between DNA packaging densities and the resulting accessibility of DNA to reactive oxygen species (ROS).

Investigation of a direct methanol redox fuel cell with design simplification
Creators: name: Ilicic, Alan Bartol
Publisher: name: University of British Columbia
Year: 2010

description: A key objective of this work is to address a number of the central issues associated with the direct methanol fuel cell (DMFC) through the investigation of a redox flow battery (RFB) / DMFC hybrid fuel cell. The air cathode (Pt/carbon) of the DMFC is substituted by a Fe²⁺/Fe³⁺ redox couple cathode (carbon) with no platinum-group metal (PGM) catalyst. In this configuration, referred to as the direct liquid redox fuel cell (DLRFC), the Fe²⁺/Fe³⁺ redox couple cathode is selective to the redox couple reaction and fuel crossover does not cause cathode depolarization. A wide range of anolyte fuel concentrations were tested (2-24 M CH₃OH) and the best DLRFC performance was obtained at 16.7 M CH₃OH (equimolar CH₃OH / H₂O). A significant improvement in the DLRFC performance and catholyte charge density was obtained by switching from a sulfate-based iron salt to a perchlorate-based iron salt. This led to a greater than 150% increase in the solubility of the redox couple, greater than a 200 mV increase in the equilibrium half-cell potential of the redox couple and a greater than 200% improvement in the DLRFC peak power density (79 mW/cm² vs. 25 mW/cm²) relative to the sulfate-based system. The selective nature of the redox cathode enabled the demonstration and characterization of a novel mixed-reactant DLRFC (MR-DLRFC) where a mixed electrolyte containing methanol and the redox couple is fed to the cathode and fuel crossover is the mode of fuel supply. A non-optimized peak power density of 15 mW/cm² was obtained with this system. A novel in-situ redox couple regeneration approach was also demonstrated and characterized, which involved substituting the methanol anolyte by an air stream. This approach exploits the hybrid nature of the DLRFC and utilizes the PtRu catalyst at the DLRFC anode as an O₂ reduction cathode during regeneration. Eliminating the use of PGM catalysts at the fuel cell cathode and enabling the use of high fuel concentrations are decisive advantages of DLRFC technology. Furthermore, the ability to extend DLRFC technology to a mixed-reactant architecture where fuel crossover is desirable paves new ground for the future of fuel cell research.

description: Two mechanisms of two-color (ω+ 2ω) laser-induced field-free molecular orientation, based on the hyperpolarizability and ionization depletion, are explored and compared. The CO molecule is used as a computational example. While the hyperpolarizability mechanism generates small amounts of orientation at intensities below the ionization threshold, ionization depletion quickly becomes the dominant mechanism as soon as ionizing intensities are reached. Only the ionization mechanism leads to substantial orientation (e.g. on the order of || > 0.1). For intensities typical of laser-induced molecular alignment and orientation experiments, the two mechanism lead to robust, characteristic timings of the field-free orientation wave-packet revivals relative to the the alignment revivals and the revival time. The revival timings can be used to detect the active orientation mechanism experimentally.

description: The NMFS Galveston Reef Fish Observer Program began mandatory coverage of the Gulf of Mexico commercial reef fish fishery in July 2006. Since that time the program has recorded catch data from vessels using multiple gear types (vertical line, bottom longline, spearfishing, and buoy fishing) across broad spatial and temporal scales (Scott-Denton et al., 2011; Scott- Denton and Williams, 2013). While at-sea, fishery observers record characteristics of individual captured fish such as length, weight, discard disposition, location, and other environmental factors (NMFS, 2016). Length and weight data obtained from at-sea fishery observer programs are often useful because they include information about species not landed, e.g. non-target species, or for size ranges of target species typically discarded at-sea. Length-weight regression models are used extensively to estimate weight from length because of the technical difficulties in obtaining accurate weights while in the field. The purpose of this document is to provide length-weight relationships, location, and depth distributions for target and non-target reef fish species using data collected by the Galveston Reef Fish Observer Program from July 2006 through December 2015.

Surface scattering velocities in III-nitride quantum well laser structures via the emission of hybrid phonons

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We have theoretically and numerically studied nitride-based quantum well (QW) laser structures. More specifically, we have used a QW made with III-nitride where the width of the barrier region is large relative to the electron mean free path, and we have calculated the electron surface capture velocities by considering an electron flux which is captured into the well region. The process is assisted by the emission of the longitudinal optical phonons as predicted by the hybrid (HB) model. The results of surface capture velocities via the emission of HB phonons are compared to the emission of the dielectric continuum phonons (Zakhleniuk et al 1999 Phys. Status Solidi a 176 79). Our investigation shows that the two different phonon models predict almost the same results for the non-retarded limit. Furthermore, the surface capture velocities strongly depend on the size of the structure and the heterostructure materials. Lastly, a comparison to the recent experimental values shows that our model could accurately describe the experimentally measured parameters of the quantum capture processes.

description: Detroit’s history of systemic racial inequity has significantly contributed to the uneven development patterns of the entire metropolitan region that persist to this day. The process of central city decline, deindustrialization, and suburban migration in the post-war period compounded existing discrimination in housing and employment for Black residents, effectively trapping them in the city and preventing them from accessing suburban amenities. This dissertation evaluates the role that public transportation planning played in reinforcing racial segregation by restricting transit options to suburban areas, effectually limiting physical mobility of residents. My research demonstrates that the City of Detroit Department of Street Railways (DSR) had knowledge of suburban growth trends, sufficient budget revenues, legal jurisdiction, and the physical resources to provide service to suburban areas, but voluntarily limited suburban transit options. The failure to provide suburban service meant that the DSR could not capitalize on regional growth trends and could not recover from lost ridership numbers as Detroit depopulated through white flight and decentralization. This study analyzes key transportation planning decisions made by City of Detroit officials between 1922 and 1973 using qualitative, primary-source, archival records such as letters, meeting minutes, reports, survey documents, and maps. These sources have not been comprehensively researched or peer-reviewed to date, and my research contributes to a literature gap in the history of public transportation planning in the City of Detroit. Findings are determined using interpretive analysis to understand the role that transportation planning has played in reinforcing racial segregation between city and suburb in post-war Detroit.

description: The cement industry is generally considered responsible for upwards of 5% of anthropogenic greenhouse gas emissions. This is a result of the high energy intensity of the process, significant CO$_2$ release from the raw materials used, and large global consumption. It is also a high growth sector as emerging economies develop their infrastructure. This paper outlines an investigation into day-to-day performance variation that, if scaled to the global level, represents a potential for improvement of up to 100 Mt CO$_2$ equivalent per year. Optimising this operational variation is not included in current roadmaps for reduction of cement industry CO$_2$ emissions, and has the potential to be cost neutral, or even save money for cement producing companies. The paper analyses a case study of a plant in the UK, operating a pre-calciner type kiln commissioned in 1986. Production data was analysed to examine the day-to-day variation in the fuel-derived CO$_2$ emissions, in order to estimate the potential for operational improvement. Various factors were then analysed to determine what drives this potential improvement, including fuel mix, rate of production, and process airflow. The day-to-day performance of the plant, as measured by the fuel-derived CO$_2$ emissions per tonne of clinker produced, varied significantly. (Clinker is the material ground and mixed with ~3% gypsum to produce cement). Improvement of the plant to 10th percentile best observed performance levels would represent a 10% drop in CO$_2$ emissions and a 7% drop in energy consumption, with associated cost savings. Two mathematical models were used, first to examine the energy balance of the plant and then to predict CO$_2$ emissions from given input conditions. The largest source of energy consumption was the dissociation energy required to form clinker, however, the variation in this was small. Airflow and fuel type were found to dominate the variation of performance. Optimising the factors affecting performance was predicted to reduce energy consumption by 8.5% and CO$_2$ emissions by 19.5%. The paper concludes that there exists significant opportunity to reduce the emissions from cement plants by operational means, and that fuel mix and excess air ratio should be the focus of future research.

description: La innovación educativa lleva décadas en los centros de formación, principalmente impulsada por el profesorado. En los últimos años las universidades y organismos de gestión de la formación han creado servicios de innovación educativa para potenciar su utilización y contribuir a la divulgación de la misma. Los cambios drásticos en la formación presencial han puesto a prueba la transferencia de la innovación educativa para ayudar a realizar la transición de formación presencial a formación online. Al profesorado que ya hacía innovación educativa no le resultó difícil la transición ¿pero al resto? ¿Cómo le ha ayudado los servicios de innovación educativa? ¿Qué lecciones podemos sacar de esta situación? A estas preguntas se pretende dar respuesta en la conferencia titulada “El papel de la innovación educativa en la nueva normalidad académica”. La conferencia está enmarcada en el Congreso de Educación, Innovación y Nueva Normalidad organizado por la Asociación Normalista de Docentes Investigadores (ANDIAC), el Centro de Investigación e Innovación para el Desarrollo Educativo (CIIDE) y el Centro de Capacitación y Desarrollo de la Secretaría de Educación del Estado de Durango (CECADE). El congreso se celebró el 9 y 10 de diciembre de 2020.

description: We investigate - with Monte Carlo computer simulations - the phase behaviour of dimeric colloidal molecules on periodic substrates with square symmetry. The molecules are formed in a two-dimensional suspension of like charged colloids subject to periodic external confinement, which can be experimentally realized by optical methods. We study the evolution of positional and orientational order by varying the temperature across the melting transition. We propose and evaluate appropriate order parameters as well as the specific heat capacity and show that the decay of positional correlations belongs to a class of crossover transitions while the orientational melting is a second-order phase transition.

description: The organism Clostridium thermocellum grows on cellulosic substrates and produces ethanol, acetate, lactate, formic acid, and CO2. The organic acids produced alter the growth environment in which the bacteria grows and ultimately inhibit bacterial growth. One method which has been used successfully to maintain the system at acceptable growth conditions is to intermittently flush out the spent media and metabolic products and replace with new fermentation media. Our goal was to design and build an automated system that will automatically flush the spent media from the growing culture and resupply new media without manual intervention. An automated control system was designed and built to control growth parameters. Heated water was pumped through the jacket of each culture vessel and used to regulate the reactor temperature. Sensors for pH and temperature were connected to a central data acquisition system and NI LabVIEW software was used to control each of the components through the signals provided by the data acquisition system. Peristaltic and vacuum pumps were used to supply growth media and acquire reproducible samples for HPLC analysis with limited contamination. In a series of trials, targeted temperature and moisture conditions were achieved and new media was passed through each reactor using a time trigger. More product was produced in manual and automatically flushed cultures than in batch.

description: We analyse the CMB radiation in spherical 3-spaces with non-trivial topology. The focus is put on an inhomogeneous space which possesses observer dependent CMB properties. The suppression of the CMB anisotropies on large angular scales is analysed with respect to the position of the CMB observer. The equivalence of a lens space with a Platonic cubic space is shown and used for the harmonic analysis. We give the transformation of the CMB multipole radiation amplitude as a function of the position of the observer. General sum rules are obtained in terms of the squares of the expansion coefficients for invariant polynomials on the 3-sphere.
The Impact of Receiver Sex on Feedback Message Choice by Supervisors and the Influence on Employees' Attitudes and Behaviors
Creators: name: Slone, Amanda Ruth
Publisher: name: University of Kentucky
Year: 2016
Subjects: subject: Organizational Communication

description: The present study investigated the influence of receiver sex on supervisor’s feedback message choice, and the influence of the interaction between receiver sex and feedback message type on employees’ subsequent behaviors and attitudes. Participants (N = 45) included a representative sample from a reputable organization in the southeastern United States. Both quantitative and qualitative data were collected using a survey methodology. This mixed-methods approach revealed that while participants in this study rated the overall atmosphere of the performance evaluation as positive and informal, the interaction between receiver sex and feedback message type did have a statistically significant influence on their perceived utility of the feedback message, retention of the feedback message, and motivation to implement the feedback. In addition, women in this sample reported receiving significantly different types of feedback than did men. Therefore, supervisors should ensure that both men and women receive more task performance related feedback messages in order to increase employees’ perceived utility of the feedback message, retention of the feedback message, and motivation to implement the feedback.

description: We consider a class of pseudodifferential operators with a doubly characteristic point, where the quadratic part of the symbol fails to be elliptic but obeys an averaging assumption. Under suitable additional assumptions, semiclassical resolvent estimates are established, where the modulus of the spectral parameter is allowed to grow slightly more rapidly than the semiclassical parameter.

Characterization of structural degradation in a polymer electrolyte membrane fuel cell cathode catalyst layer
Creators: name: Young, Alan P.
Publisher: name: University of British Columbia
Year: 2010

description: This study investigated the structural degradation of a polymer electrolyte membrane fuel cell (PEMFC) due to carbon corrosion and ionomer degradation. Cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM), and polarization analyses were completed to characterize and correlate the structural degradation to the performance. Accelerated stress tests (AST) were used to produce the different known degradation mechanisms. Both failure mechanisms had unique fingerprints on the performance degradation. The carbon corrosion results showed a clear thinning of the cathode catalyst layer (CCL) and gas diffusion carbon sub-layer, and a reduction in the effective platinum surface area caused by the carbon support oxidation. The degradation of the CCL and carbon sub-layer altered the water management, as evidenced by an increase of the voltage losses associated with oxygen mass transport and CL ohmic resistance. The ionomer degradation AST showed that greater ionomer in the CCL resulted in greater platinum content in the membrane and a higher fluoride washout rate, suggesting the higher ionomer content facilitated the mass transfer of contaminants (such as dissolved platinum and iron) into the membrane. It is proposed that H2O2 was produced at the anode, diffused into the membrane, and decomposed at the platinum and/or iron sites bound in the membrane structure. The decomposition products attacked the ionomer both in the bulk phase and CCL causing: i) membrane thinning which exacerbated H2 crossover, ii) lower membrane conductivity, and iii) CL structure degradation, resulting in increased reaction penetration into the CL and decreased effective oxygen diffusivity due to changes in CL water content. A method using an electrochemical quartz microbalance (EQCM) was investigated to further evaluate ionomer degradation. Mimicking the ionomer films in the CCL on the EQCM would enable a quantitative method to further evaluate the degradation reactions and overall mechanism. While this technique was not fully developed, background on the EQCM and the work to date is presented as a starting point for future development.
