description: In order to determine the angiogenic requirement(s) for ANTXR1, ANTXR2, and MMP14 by removing these genes pairwise specifically in endothelial, pericyte, and smooth muscle cells during sprouting angiogenesis. The mouse retina is a common model used to study sprouting angiogenesis. Vascularization begins when pups are born P(0) and stays confined to a two-dimensional plane. The effects of temporal loss of two loxP flanked alleles during sprouting angiogenesis were evaluated at P(5). Harvested P(5) retina were IHC stained and analyzed for outgrowth, major vessels, branching morphology, & vessel density at the periphery. qPCR analysis of lung and kidney tissue from ANTXR1-/-; R26R-Cre mice validated excision of the ANTXR1 allele. Nine mutant strains were developed using three promotor-driven Cre lines and a combination of two of three alleles. The PDGFRβ-Cre strains lagged slightly due to non-mendelian inheritance of PDGFRβ-Cre. EC specific conditional loss of function mutant mice were studied to elucidate the roles ANTXR1, ANTXR2, and MMP14 play in sprouting angiogenesis and ECM remodeling. No significant phenotypic differences found between endothelial-cell specific conditional loss mice and inter-litter controls.

description: To mitigate climate change, it is important to capture carbon dioxide. This thesis examines the capture of CO2 from gas mixtures using semi-clathrate hydrate (SCH) formation. It identifies SCH, which are stable at mild temperature and pressure conditions favourable to industrial processes, and explores the separation of gases in flue and biogas. It investigates capture primarily by entrapment in the hydrogen bonded water cages of the SCH structures but also via synergistic chemical reaction with hydroxide ions. It demonstrates that CO2 can be readily separated by SCH formation and a low energy regeneration process may be possible.

Subjects: Uncategorized

description: Introduction: The osteoinductive properties of a bone graft material are critical to the success of dentoalveolar reconstruction. This study aims to investigate the osteoblastic response by evaluating bone volume after 4 and 8 weeks, and osteoinductive expression markers (BMP-2 and Runx2) across three widely available graft material types (demineralized human bone matrix, mineralized human bone, and deproteinized bovine bone) using a rat calvaria model. Methods: Twenty-four (24) rats had two 5mm defects placed per calvaria. Rats were divided into 4 groups: bovine xenograft (XG), demineralized bone matrix (DBM), mineralized bone graft (MBG) and a collagen membrane control (CC) group. Within each group, samples were collected at two time points, 4 weeks (T4) and 8 weeks (T8). After 4 and 8 weeks of integration, all calvariae were scanned using a Scanco model 40 μCT. DICOM files were rendered, then analyzed using MatLab software, which produced bone volume values. Samples were fixed and subsequently demineralized for immunohistochemistry and histomorphometry. Slides were mounted and stained with H&E stain as well as BMP-2 and Runx2 markers. Number of osteoblasts expressing BMP-2 and Runx2 was counted for each group and analyzed. Results: At 4 weeks, DBM showed low mineral density (7.7%) as compared to the control (25.2%) but increased dramatically at 8 weeks (DBM, T8=27.6%; CC, T8=27.2%). Xenograft material showed an increase in mineral between T4 and T8 (XG, T4=25.0%; XG, T8=32.3%). MBG remained consistent over the 8 week trial period (MBG, T4=30.4%; MBG, T8=30.4%). BMP-2 expression was present in cells adherent to all graft materials. Runx2 expression was also observed in cells adherent to all graft materials indicating that during the 4 – 8 week healing period all materials supported osteogenesis. Conclusions: When compared to other materials, the demineralized bone matrix provided high osteoinductive properties during the 4-8 week time period based on increased mineral content. All materials were associated with immunohistological evidence of osteogenesis in the rat calvaria defect model.

description: We present an analysis of the dynamics of two-flavour QCD in the vacuum. Special attention is payed to the transition from the high energy quark-gluon regime to the low energy regime governed by hadron dynamics. This is done within a functional renormalisation group approach to QCD amended by dynamical hadronisation techniques. The latter allow us to describe conveniently the transition from the perturbative high-energy regime to the nonperturbative low-energy limit without suffering from a fine-tuning of model parameters. In the present work, we apply these techniques to two-flavour QCD with physical quark masses and show how the dynamics of the dominant low-energy degrees of freedom emerge from the underlying quark-gluon dynamics.

description: Active mobility is a key factor in the mobility revolution and is thus elementary in combating the climate crisis. At the same time, however, much research is still needed to improve the situation of active mobility, especially regarding inhibiting factors in the choice of active modes of transport. Essential here is road users' positive and negative emotional experiences in different infrastructure settings. Due to high volumes and speeds of motorised traffic, high noise and pollution levels and a lack of greenery urban space, today is often associated with increased stress and an excess of stress-related diseases such as cardiovascular diseases, depression, or schizophrenia (Adli, 2017). Providing data and objectifying much-discussed issues such as perceived safety in transport infrastructure is essential for decision-making at the community level (Sørensen, 2009). Such data can provide evidence to refine traffic planning guidelines and improve public space for pedestrians and cyclists. It is therefore necessary to get a differentiated picture of social and ecological considerations in the mobility sector. The BMDV project “Emotion Sensing for (E-)Bicycle Safety and Mobility Comfort ESSEM” investigates the subjective perception of cyclists’ safety in urban traffic. With the help of iterative environmental and body-related data collection, stress points in the municipal cycling network are identified and analysed in the two model cities of Ludwigsburg and Osnabrück . The framework given in this study applies a triangulating approach that allows statements on individual “stress” utilising biological markers (skin conductivity, skin temperature) via a sensor wristband and through standardised questionnaires. In this way, vulnerable groups can be identified, which can be better taken into account in project development and planning. This study focuses on three “stress hotspots” in Osnabrück, considering different forms of bicycle infrastructure.

description: Unmanned aerial vehicles (UAVs) have recently been successively utilized in many diverse areas, including wireless communications. Several applications have been mentioned for UAV-assisted communications including UAVs acting as base stations and data collection units for Internet of Things (IoT). Despite their effectiveness, there are still several fundamental challenges in UAV wireless systems that are yet to be resolved, mainly due to the practical constraints imposed by the UAV terminals. In this thesis, we aim to resolve some of these challenges to provide energy efficient, reliable, and high-rate deployment of UAVs. In particular, we study (i) optimal placement and trajectory design of UAVs to minimize the average user power consumption subject to a movement constraint on UAVs, (ii) optimal deployment of UAVs to minimize the user outage probability, and (iii) deep-learning assisted predictive deployment of UAVs for rate maximization. For all the studied scenarios, we consider practical wireless channel models specifically tailored for UAV communications. We also provide quantization-theory based analytical expressions and distributed numerical algorithms for optimal deployments and trajectory planning of UAVs.

description: A good deal of current research in complex networks involves the characterization and/or classification of the topological properties of given structures, which has motivated several respective measurements. This letter proposes a framework for evaluating the quality of complex network measurements in terms of their effective resolution, degree of degeneracy and discriminability. The potential of the suggested approach is illustrated with respect to comparing the characterization of several model and real-world networks by using concentric and symmetry measurements. The results indicate a markedly superior performance for the latter type of mapping.
title: Care and gender: A time worn narrative? Perceptions of carework in the Scottish out of school care workforce
Creators: name: Anderson, Penny
Publisher: name: University of Glasgow
Year: 2023

description: This is a small-scale temporal study that highlights the lived experiences of five women practitioners employed in the Scottish Out of School Care (OSC) workforce, also known internationally as school-aged childcare (SAC). The five practitioners entered the childcare profession without a relevant professional qualification. Whilst play and learning are central themes of school-aged childcare both nationally and internationally, the focus of this study examines the temporal nature of care experiences in relation to gender, seats of power and constructions of the good enough mother. It focuses on the care experiences, careers, and aspirations of the women over their life course: past, present, and beyond. The five practitioners were initially interviewed through the aid of a temporal tool, the biographical life grid, which was employed to assist reflexive biographical narrative interviews. The biographical life grid is a visual method frequently used to capture past and present memories of life events, and as such often offers a further window into the perceptions surrounding those memories. The life grid was substituted reflexively for two simple 24-hour clocks to map both chronological and felt-time reflections as the study progressed. This study aims to capture a time element, relating not only to professional aspirations but also to the constructions of the women’s developing sense of a caring self. A feminist Foucauldian, poststructural lens is applied to interpret the biographical narratives in what is arguably a gendered profession. The analysis of the narratives considers how constructions on caring both in private and professional lives may be influenced over time through engagement with family, society, professional requirements and discourse in policy. Foucauldian discourse analysis is employed to interpret how seats of power, particularly emanating from the self, may affect the practitioner’s decision making in relation to career choices. Interpretations arising from the discourse analysis on the findings subsequently considers any resulting relevance for the future of recruitment, retention, and career resilience not only for the Scottish Out of School Care (OSC) workforce but also potentially for all professional caring employment.
Intestinal FFA2 and FFA3 Mediate Obesogenic Effects in Mice on a Western Diet

description: Free fatty acid receptor 2 (FFA2) and free fatty acid receptor 3 (FFA3) are two highly similar G protein-coupled receptors belonging to the free fatty acid receptor family. Their ligands are short-chain fatty acids (SCFAs), which are produced by the gut microbiome and play diverse roles in physiological function, including the regulation of metabolic homeostasis and glycemic control. FFA2 and FFA3 are broadly expressed in a multitude of tissues including the intestine, pancreas, adipose and central nervous system, where they contribute to metabolic homeostasis via a summation of their tissue specific effects. FFA2 and FFA3 are highly expressed within the intestinal epithelium – the major site of SCFA generation – and have been identified in hormone-secreting enteroendocrine cells as well as intestinal epithelial cells. However, due conflicting data, the respective roles of FFA2 and FFA3 within the intestine and their effects on physiology and metabolism are still largely unclear. Previous in vivo studies involving these receptors have largely relied on global knockout mouse models, making it difficult to characterize their intestine-specific effects. To overcome this challenge, we generated novel intestine-specific knockout mouse models for FFA2 and FFA3 individually and report the first in vivo characterization of each receptor in the intestine while revealing novel insights into their functions. Following model validation, we conducted a general metabolic assessment of male Villin-Cre FFA2 (Vil-FFA2) and Villin-Cre-FFA3 (Vil-FFA3) mice on standard chow diet and observed no congenital or time-dependent defects. Because dietary changes are known to alter the composition of the gut microbiome, and thereby SCFA production, a long-term obesogenic challenge was performed on male Vil-FFA2 and Vil-FFA3 mice and their littermate controls to probe for a phenotype on a high fat, high-sugar “Western diet.” Mice were placed on either a low-fat control diet (CD) or Western diet (WD) at 10 weeks of age and metabolically profiled for 25 weeks. We found that both Vil-FFA2 and Vil FFA3 mouse strains were largely protected from diet-induced obesity and developed significantly less fat mass as well as reduced adipocyte hypertrophy in both subcutaneous and visceral adipose tissues. iii In the WD-fed Vil-FFA2 group, these effects were partially driven by a significant reduction in food intake. Collectively, these findings indicate a novel role of intestinal FFA2 and FFA3 in mediating the metabolic consequences of a Western diet. Moreover, these data support an intestine-specific role of FFA2 and FFA3 in whole-body metabolic homeostasis and in the development of obesity.

description: We propose and develop the complex scaled multiconfigurational spin-tensor electron propagator (CMCSTEP) technique for theoretical determination of resonance parameters with electron-atom/molecule systems including open-shell and highly correlated atoms and molecules. The multiconfigurational spin-tensor electron propagator method (MCSTEP) developed and implemented by Yeager his coworkers in real space gives very accurate and reliable ionization potentials and attachment energies. The CMCSTEP method uses a complex scaled multiconfigurational self-consistent field (CMCSCF) state as an initial state along with a dilated Hamiltonian where all of the electronic coordinates are scaled by a complex factor. CMCSCF was developed and applied successfully to resonance problems earlier. We apply the CMCSTEP method to get $^2 P\,\mbox{Be}^{-}$ shape resonance parameters using $14s11p5d$, $14s14p2d$, and $14s14p5d$ basis sets with a $2s2p3d$\,CAS. The obtained value of the resonance parameters are compared to previous results. This is the first time CMCSTEP has been developed and used for a resonance problem. It will be among the most accurate and reliable techniques. Vertical ionization potentials and attachment energies in real space are typically within $\pm 0.2\,eV$ or better of excellent experiments and full configuration interaction calculations with a good basis set. We expect the same sort of agreement in complex space.

dataflow programming paradigms

description: Challenges introduced by highly hybrid many-cores architectures have a lasting impact on the portability and performance of applications, partially due to traditional programming paradigms. These programming paradigms lack the flexibility and capabilities required to deal with large amounts of potential parallelism and a dynamic hybrid execution environment, putting the performance and scalability of applications at risk. Advances in task-based runtime have shown to provide a plausible solution to this problem, one that not only increase the domain scientists’ productivity but also deliver codes that are more efficient, more scalable, and more adaptable to various hardware architectures, and show an increased portability potential to transition from one generation of hardware to another. This talk will describe a distributed task-based runtime, PaRSEC, and highlight its data management strategies and features to allow the implementation of highly efficient and scalable algorithms at any scale.

description: Cyanobacteria have been a focus of research as a prominent producer of secondary metabolites which possess unique activities and structural components. In this thesis, we showcase the value of dereplication strategies using untargeted MS/MS, GNPS molecular networking, NMR spectroscopy, and bioassay guided fractionation to identify known and novel natural products from cyanobacterial cultures UIC 10885 and UIC 10832. Within this paper we report the isolation and identification of a series of Hassallidin C and D analogues from UIC 10885, which were isolated by semi-preparative HPLC and analyzed using MS/MS and H1 NMR methods. The third chapter of this thesis is dedicated to the preliminary identification of a potential novel lipopeptide from UIC 10832, which was isolated using the same methods listed above. All compounds were screened against cancer cell lines in order to identify anti-proliferative properties.

description: The spectra of baryons at LHC can explain the features of the proton spectra in cosmic rays (CR). It seems important to study all baryon data that are available from collider experiments in wide range of energies. Transverse momentum spectra of baryons from RHIC ($\sqrt(s)$=62 and 200 GeV) and from LHC ($\sqrt(s)$=0.9 and 7 TeV) have been considered. It is seen that the slope of distributions at low $p_T$'s is changing with energy. The QGSM fit of these spectra gives the average transverse momenta which behave as $s^{0.06}$ that is similar to the previously observed behavior of $Λ^0$ hyperon spectra. The change in average transverse momenta that are slowly growing in VHE hadron interactions at CR detectors cannot cause the "knee" in measured cosmic ray proton spectra. In addition, the available data on heavy quark hadron production from LHC-b at $\sqrt{s}$=7 TeV were also studied. The preliminary dependence of hadron average transverse momenta on their masses at LHC energy is presented. The possible source of cosmic ray antiparticle-to-particle ratios that are growing with energy was analyzed in the framework of QGSM, where the growing ratios are the result of local leading asymmetry between the production spectra of baryons and antibaryons in the kinematical region of proton target fragmentation. In the laboratory system of cosmic ray measurements this spectrum asymmetry will be seen as growing ratio of secondary antiparticle-to-particle spectra until the certain energy of secondaries. This conclusion makes the particle production at the sources of very high energy cosmic protons important, if the interactions with positive target matter would have place in proximity of these sources.

description: Strain-clocked dipole-coupled nanomagnetic logic is an energy-efficient Boolean logic paradigm whose progress has been stymied by its propensity for high error rates. In an effort to mitigate this problem, we have studied the effect of nanomagnet geometry on error rates, focusing on elliptical and cylindrical geometries. We had previously reported that the out-of-plane excursion of the magnetization vector during switching creates a precessional torque that is responsible for high switching error probability in elliptical nanomagnet geometries. The absence of this torque in cylindrical magnets portends lower error rates, but our simulations show that the error rate actually does not improve significantly compared to elliptical magnets while the switching becomes unacceptably slow. Here, we show that dipole coupled nanomagnetic logic can offer relatively high reliability (switching error probability < 10^-8), moderate clock speed (~ 100 MHz) and 2-3 orders of magnitude energy saving compared to CMOS devices, provided the shape anisotropy energy barrier of the magnet is increased to at least ~5.5 eV to allow engineering a stronger dipole coupling between neighboring nanomagnets.

Future singularities for two kinds of equation of state (barotropic perfect fluid and generalized form of equation of state) are studied. While no future singularity is found for the first case, some kind of singularity is found to be possible for the second. We also investigate $f(R,T)$ gravity by the method of dynamical systems and obtain some fixed points. Finally, the effect of the Noether symmetry on $f(R,T)$ is studied and the consistent form of $f(R,T)$ function is found using the symmetry and the conserved charge.

description: The 11.2 $μ$m emission band belongs to the family of the `Unidentified' Infrared (UIR) emission bands seen in many astronomical environments. In this work we present a theoretical interpretation of the band characteristics and profile variation for a number of astrophysical sources in which the carriers are subject to a range of physical conditions. The results of Density Functional Theory (DFT) calculations for the solo out-of-plane (OOP) vibrational bending modes of large polycyclic aromatic hydrocarbon (PAH) molecules are used as input for a detailed emission model which includes the temperature and mass dependence of PAH band wavelength, and a PAH mass distribution that varies with object. Comparison of the model with astronomical spectra indicates that the 11.2 $μ$m band asymmetry and profile variation can be explained principally in terms of the mass distribution of neutral PAHs with a small contribution from anharmonic effects.

description: Arsenic is a known human carcinogen and relevant environmental contaminant in drinking water systems. We set out to comprehensively examine statewide arsenic trends and identify areas of public health concern. Specifically, arsenic trends in North Carolina private wells were evaluated over an eleven-year period using the North Carolina Department of Health and Human Services (NCDHHS) database for private domestic well waters. We geocoded over 63,000 domestic well measurements by applying a novel geocoding algorithm and error validation scheme. Arsenic measurements and geographical coordinates for database entries were mapped using Geographic Information System (GIS) techniques. Furthermore, we employed a Bayesian Maximum Entropy (BME) geostatistical framework, which accounts for geocoding error to better estimate arsenic values across the state and identify trends for unmonitored locations. Of the approximately 63,000 monitored wells, 7,712 showed detectable arsenic concentrations that ranged between 1 and 806 μg/L. Additionally, 1,436 well samples exceeded the EPA drinking water standard. We reveal counties of concern and demonstrate a historical pattern of elevated arsenic in some counties, particularly those located along the Carolina terrane (Carolina slate belt). We analyzed these data in the context of populations using private well water and identify counties for targeted monitoring, such as Stanly and Union Counties. By spatiotemporally mapping these data, our BME estimate revealed arsenic trends at unmonitored locations within counties and better predicted well concentrations when compared to the classical kriging method. This study reveals relevant information on the location of arsenic-contaminated private domestic wells in North Carolina and indicates potential areas at increased risk for adverse health outcomes.

description: Educational reforms have a tendency to fade or divert in unproductive ways. To disrupt this cycle and understand why unwanted practices persist and new ones distort, the supports that sustain practices need to be considered. In this study, I use action research to examine the supports of institutionalized patterns of practice within the classroom and at other levels, illuminating the interconnected web of influence that shape classroom practice. I leverage the analytical power of the MoRe Institutional Framework (Anderson & Colyvas, 2021) to investigate support mechanisms. I present a descriptive case study of practices and supports of an interdisciplinary science course for undergraduate elementary education majors. I explore supports for classroom practices of representing science and centering of students and/or teachers. My findings show patterns of practice supported in multiple ways at levels from individual to global. Implications of this study suggest ways for changing classroom practice and show how the application of the MoRe Institutional Framework to classroom systems could further inform and service reform efforts.

description: La literatura afirma falta de corresponsabilidad con respecto al reparto de tareas del hogar y de cuidados, siendo los planteamientos socio-educativos que parten de un exhaustivo análisis del contexto, la mejor herramienta para atenuarlo. Este artículo presenta resultados de una investigación cuyo objetivo principal es determinar el grado de responsabilidad-compartida entre parejas españolas en cuanto al reparto de tareas básicas y cuidado de hijos/as. La recogida de datos se realiza a través de un cuestionario ad hoc sometido a un proceso de validez y fiabilidad, con una muestra total de 1022 personas. El análisis de datos combina el estudio descriptivo porcentual y la correlación bivariada. Se obtiene diferencia significativa en el grado de implicación de las mujeres en tareas desarrolladas dentro del hogar y en el cuidado de los/as hijos/as, sin embargo, ellos lo hacen en tareas fuera del domicilio. Uno de los resultados más destacable es la diferente percepción que presentan los géneros sobre el nivel de implicación, siendo los varones los que perciben una mayor corresponsabilidad, poniendo de manifiesto cómo los roles tradicionales de género siguen permeando las estructuras fa-miliares. El documento finaliza con propuestas socio-educativas dirigidas a los diferentes agentes socio-educativos orientados a erradicar esos estereotipos.The scientific literature about the distribution of household and care tasks according, affirms the lack of co-responsibility as far as this is concerned, inside and outside the home, and care duties. The socio-educational activities that start from an in-depth analysis of reality is a useful tool to reduce this gender inequality. This article presents results derived from a research project. whose aims to measure the degree of shared responsibility among couples in Spain, focusing in domestic tasks and children care. Data collection is based on an ad hoc questionnaire whose validity and reliability are confirmed. The sample size is 1022 people. The data analysis includes descriptive statistics and bivariate correlations. There has been observed a meaningful difference in the higher degree of women’s engagement in household and children care tasks, whereas men show a bigger involvement in the performance of duties out of the house. One of the most noteworthy results is the different perceptions men and women have of the level of involvement, with men perceiving greater co-responsibility. These data demonstrate that traditional gender stereotypes continue to frame family structures. This paper ends with some socio-educational proposals aimed to eradicate these stere-otypes, for teachers, students and families.
The Sexual Politics of Contraception

description: The central problem posed in this study is the complexity of factors impinging upon young women engaging in heterosexual relationships. Why do young. women become pregnant when they do not wish to be? Whilst problems associated with the nature and use of contraceptive methods influence the incidence of unwanted pregnancy, my hypothesis is that this cannot be considered in isolation. The nature of heterosexual relationships and the contradictory position of young women are crucial factors to the extent that women face a double bind of passive femininity versus the active control required for successful fertility regulation. Investigation of this area entails examining the relationship between the public and private image: the -imposed depiction of femininity alongside the ways with which this is dealt and expressed in concrete sociosexual relationships. This study elucidates the factors influencing the incidence of unwanted pregnancy among young, single women. It is undertaken from the standpoint of women themselves using a feminist framework which investigates the sexual politics, power relations and control characterising relationships between women and men. The study is conducted by means of in-depth interviews with women who were patients at non-profit making abortion clinics. A number of interrelated areas are discussed: knowledge and use of contraception; reasons for non-use or irregular use of contraception; relationships with men; attitudes toward abortions future intentions. Analysis of the interview material suggests that the organisation of efficient contraceptive practice is influenced by a complex of factors: the nature of contraceptive techniques, the incidence of risk-taking, ambivalence towards sexuality and sexual activity. It is argued that these factors are linked with a basic contradiction characterising the transition from sexual ‘innocence’ to sexual activity. The politics of heterosexual relations are power politics and may place the young, single woman in an impossible situation. Female sexuality, it is concluded, is locked within the confines of the double standard of morality which itself is a manifestation of patriarchal control.

description: The first two chapters of my dissertation investigate how public policies can influence teacher incentives to attract and retain effective teachers and school leaders. Chapter 1 explores teacher decisions to move into school leadership and the role salary plays in those decisions. Using a performance-based pay policy with discontinuities in teacher salary because of performance, I look at teachers becoming assistant principals (APs) and APs becoming principals. I find teachers are more likely to become APs if they just miss the cutoff for a higher evaluation bin. To isolate the effect of salary on job transitions, I employ a difference-in-discontinuity methodology and conclude the main result is driven by salary and not because of other factors such as motivation or demand-driven factors. The second chapter studies the long-run effects of school accountability on educational attainment. I exploit two sources of variation: staggered implementation of accountability across states and individuals' exposure to accountability. I find 12 years of exposure to accountability increases the likelihood of graduating high school by 2.1 percentage points on average but has no statistically significant effect on college attendance or receiving a Bachelor’s degree. I rule out changes in school expenditures and teacher characteristics as potential mechanisms and present suggestive evidence that schools are classifying more students as learning disabled. Lastly, accountability is more effective in conjunction with promotion gates. The third chapter, a joint work with Dr. Erik Hembre and Shogher Ohannessian, investigates how Supplemental Nutrition Assistance Program (SNAP) eligibility and benefits affect food expenditures by exploiting the California ``cash-out'' policy, which made Supplemental Security Income (SSI) recipients ineligible for SNAP. We find affected SSI recipients increased their ``food-at-home'' budget share by 2.5 to 4.3 percentage points ($120 to $206 per quarter). The cash-out effect on total food expenditures is dampened by a decrease in ``food-away-from-home'' and driven by extra-marginal households. Comparing the consumption of in-kind versus cash transfers, we find an increase in SNAP benefits leads to a greater increase in food-at-home expenditures compared to SSI cash benefits. These findings suggest that SNAP is effective in increasing food at home consumption among its lowest income.

description: Perfluoroalkyl substances (PFASs) are widespread and persistent environmental pollutants. Previous studies, primarily among non-pregnant individuals, suggest positive associations between PFAS levels and certain blood lipids. If there is a causal link between PFAS concentrations and elevated lipids during pregnancy, this may suggest a mechanism by which PFAS exposure leads to certain adverse pregnancy outcomes, including preeclampsia.

description: Given a set of points $P \subset \mathbb F_q^2$ such that $|P|\geq q^{3/2}$ it is established that $|P|$ determines $Ω(q^2)$ distinct perpendicular bisectors. It is also proven that, if $|P| \geq q^{4/3}$, then for a positive proportion of points $a \in P$, we have $$|\{\| a- b\|: b \in P\}|=Ω(q),$$ where $\|a- b\|$ is the distance between points $a$ and $b$. The latter result represents an improvement on a result of Chapman et al. (arxiv:0903.4218).

Multiple Imputation Approaches for Multivariate Data with Missing and Censored Values

description: In this dissertation, we address the problem of imputing missing and censored values simultaneously in the multivariate data. Motivation of this research is the need to analyze the NHANES where data are subject to missing values and limits of detection. We propose two imputation frameworks to address these issues. The first framework imputes missing and censored values based on the multivariate normality assumption on the full data. The second framework imputes the missing and censored values by separately modeling the outcome variable and the covariates. The model for outcome given covariates can be flexibly specified with the covariates assumed to be normally distributed. A particular focus of the latter framework is on the missing and censored covariate problems in the Cox regression model. The censored survival outcomes and the missing and/or censored covariates are imputed simultaneously in our proposed approach. All proposed approaches are based on the missing at random (MAR) assumption, which assumes the missing values depend only on the observed values, but are unrelated with the unobserved values, and the non-informative censoring assumption, which assumes that the censoring times and the failure times are statistically independent given the observed covariate values. The performance of the proposed approaches are compared through simulation studies with popular existing MI approaches, such as the MICE (Multiple Imputation via Chained Equation) approach. The simulation studies suggest the proposed approaches have better performance in terms of correcting possible bias in the estimator and gaining estimation efficiency. The proposed approaches are applied to two real data examples.
