Custodial grandmothers
Qualitative

description: As there is an absent generation of parents due to the current ills of society such as drug and alcohol addictions, the AIDS/HIV epidemic, parental neglect and abandonment, incarcerations, mental illness and the deaths of parents, there will be an absent generation of grandparents - grandmothers in particular - for the present generation of grandchildren when they, themselves, become parents. State and other agencies will become more overburdened with assuming the care for the children of this present generation of grandchildren. This descriptive and exploratory study was designed to explore the life experiences, values, beliefs, coping mechanisms, and strengths of single, mostly low-income, African American grandmothers who are raising their grandchildren.  These custodial grandmothers are raising their grandchildren without either parent in the home. The grandmothers live in an urban, inner city area of Las Vegas, Nevada, in an area known as the Westside. Data were collected through individual interviews and focus group discussions. The study found that many of the grandmothers prefer not to accept needed assistance from social services agencies or engage with helping professionals because of their belief that no one is interested or concerned about their perceptions; their experiences, values, and beliefs; how they manage to care for the grandchildren; or their strengths. They believe that they do not have a voice in policies and procedures that affect them and their grandchildren. To assist themselves, they agreed to adopt the methods of slave women where many had to raise their children without the benefit of a spouse or other assistance. The participants in this study were willing to engage with each other as a strengths-based, self-help support group within their community, offering each other their strengths, suggestions, and solutions to what they perceive as problematic.

description: By exploiting the connection between a popular construction of a well-known skew-normal distribution and an absolute autoregressive process, we show how the stochastic process approach can lead to other skew symmetric distributions, including a skew-Cauchy distribution and some singular distributions. In so doing, we also correct an erroneous skew-Cauchy-distribution in the literature. We discuss the estimation, for dependent data, of the key parameter relating to the skewness.

description: Let $X$ be a complete measure space of finite measure. The Lebesgue transform of an integrable function $f$ on $X$ encodes the collection of all the mean-values of $f$ on all measurable subsets of $X$ of positive measure. In the problem of the differentiation of integrals, one seeks to recapture $f$ from its Lebesgue transform. In previous work we showed that, in all known results, $f$ may be recaputed from its Lebesgue transform by means of a limiting process associated to an appropriate family of filters defined on the collection of all measurable subsets of $X$ of positive measure. The first result of the present work is that the existence of such a limiting process is equivalent to the existence of a Von Neumann-Maharam lifting of $X$.
 In the second result of this work we provide an independent argument that shows that the recourse to filters is a \textit{necessary consequence} of the requirement that the process of recapturing $f$ from its mean-values is associated to a \textit{natural transformation}, in the sense of category theory. This result essentially follows from the Yoneda lemma. As far as we know, this is the first instance of a significant interaction between category theory and the problem of the differentiation of integrals.
 In the Appendix we have proved, in a precise sense, that \textit{natural transformations fall within the general concept of homomorphism}. As far as we know, this is a novel conclusion: Although it is often said that natural transformations are homomorphisms of functors, this statement appears to be presented as a mere analogy, not in a precise technical sense. In order to achieve this result, we had to bring to the foreground a notion that is implicit in the subject but has remained hidden in the background, i.e., that of \textit{partial magma}.

description: Identifying the most influential nodes in networked systems is of vital importance to optimize their function and control. Several scalar metrics have been proposed to that effect, but the recent shift in focus towards network structures which go beyond a simple collection of dyadic interactions has rendered them void of performance guarantees. We here introduce a new measure of node's centrality, which is no longer a scalar value, but a vector with dimension one lower than the highest order of interaction in a hypergraph. Such a vectorial measure is linked to the eigenvector centrality for networks containing only dyadic interactions, but it has a significant added value in all other situations where interactions occur at higher-orders. In particular, it is able to unveil different roles which may be played by the same node at different orders of interactions -- information that is otherwise impossible to retrieve by single scalar measures. We demonstrate the efficacy of our measure with applications to synthetic networks and to three real world hypergraphs, and compare our results with those obtained by applying other scalar measures of centrality proposed in the literature.

Women's participation in an interview-based study on sexual assault disclosures

Year: 2012
Subjects: Rape victims

Rape--Research

description: The purpose of this study was to develop a conceptual model of women's experiences of participating in qualitative research on a traumatic topic, namely sexual assault. Prior literature addressed participants' motivations to participate in a study, their experience of participating, and the effects of participating. However, this research does not connect to provide a holistic understanding of participants' experiences. Research questions were the following: 1.) How did research participants who participated in personal interviews on traumatic events experience the research process? 2.) What motivated women who had been sexually assaulted to agree to participate in an interview-based study of their experiences of trauma? 3.) How did these women experience their participation in the research from their first awareness of the study, throughout the study, and after the study ended? 4.) What benefits or harms did these women identify as a result of participating in the study? Women who participated in an interview-based study on sexual assault disclosures participated in individual interviews and follow-up interviews about their experience of participating in the prior study. Using a feminist paradigm and grounded theory design and analysis, the results indicated two core themes: (a) Safety and (Dis)comfort; (b) Relationships (including the subthemes of the participant's relationship with herself, her relationship to the researcher, and her relationship to other women, both those who participated in the prior study and those who are affected by sexual trauma). These two themes influenced five different segments of the Temporal Process of Research Participation: (a) Decision to Participate; (b) The Interview; (c) After the Interview; (d) The Write-up; (e) Long-Term Growth and Challenges. Based on these results, there are implications for conducting qualitative research on sensitive topics and for clinicians working with trauma survivors who may participate in a research study on their experience of trauma. For example, researchers should consider informed consent an ongoing process and help participants navigate unexpected reactions to participating. Researchers should provide a diversity of ways for people to participate in ways that feel comfortable to them. Researchers should engage in multiple follow-up contacts with participants as the effects of participating may occur over time.

description: The local and global control results for a general higher-order KdV-type operator posed on the unit circle are presented. Using spectral analysis, we are able to prove local results, that is, the equation is locally controllable and exponentially stable. To extend the local results to the global one we captured the smoothing properties of the Bourgain spaces, the so-called propagation of singularities, which are proved with a new perspective. These propagation, together with the Strichartz estimates, are the key to extending the local control properties to the global one, precisely, higher-order KdV-type equations are globally controllable and exponentially stabilizable in the Sobolev space $H^{s}(\mathbb{T})$ for any $s \geq 0$. Our results recover previous results in the literature for the KdV and Kawahara equations and extend, for a general higher-order operator of KdV-type, the Strichartz estimates as well as the propagation results, which are the main novelties of this work.

description: Photon propagator for power-law inflation is considered in the general covariant gauges within the canonical quantization formalism. Photon mode functions in covariant gauges are considerably more complicated than their scalar counterparts, except for the special choice of the gauge-fixing parameter we call the simple covariant gauge. We explicitly construct the position space photon propagator in the simple covariant gauge, and find the result considerably more complicated than its scalar counterpart. This is because of the need for explicitly inverting the Laplace operator acting on the scalar propagator, which results in Appell's fourth function. Our propagator correctly reproduces the de Sitter and flat space limits. We use this propagator to compute two simple observables: the off-coincident field strength-field strength correlator and the energy-momentum tensor, both of which yield consistent results. As a spinoff of our computation we also give the exact expression for the Coulomb gauge propagator in power-law inflation in arbitrary dimensions.

description: The rheology and interfacial tension of biomaterials are important factors governing their potential use in biomedical applications. This dissertation presents a study of the rheology and interfacial tension of three  very different biomaterials: (1) A hydrophobically modified Hyaluronic acid (HA) with polypeptide side chains, (2) Actin fibers and (3) a highly hydrophobic fluoroalkane, Perfluoropentane, and the effect of various surfactants and their mixtures on lowering its interfacial tension in an aqueous interface. In Chapter 1, we present a description of the properties and applications of these materials and a detailed literature review relevant to our studies to better understand the  motivation of our work. In Chapter 2 we describe the techniques used for our studies. In Chapter 3, we present our studies on the hydrophobically modified HA with polyleucine side chains and compare them to unmodified HA of same or similar backbone molecular weights. We found a significantly enhanced viscosity for the modified HA compared to unmodified HA at the same concentration. We also found a viscoelastic behavior that was dependent on the concentration of the solution and grafting ratio of the hydrophobic side chains. The associative thickening properties of modified HA investigated with various rheological experiments and simulation results are presented in this chapter.

description: The program HiggsBounds is a well-established tool for testing Beyond-the-Standard Model (BSM) theories with an extended Higgs sector against experimental limits from collider searches at LEP, Tevatron and LHC. Thus far, it could be applied to any neutral or charged Higgs bosons originating from the modified Higgs sector. Implicitly, these particles were assumed to exhibit a somewhat hierarchical Yukawa structure as present in the Standard Model, where in particular the couplings to first generation fermions could be neglected. In this work, we extend the HiggsBounds functionalities to go beyond these restrictions, thus making the code applicable to any neutral or charged BSM scalars. Moreover, we develop a new approach to implement experimental searches whose kinematic acceptance depends significantly on the values of the involved couplings. We achieve this by recasting the searches to general scalar models. Using this approach we incorporate relevant current experimental limits from LHC searches for exotic scalars, and present the implications of these limits for a dark matter scalar mediator model, a flipped Two-Higgs-Doublet Model and a supersymmetric model with R-parity violation.

description: This paper presents a novel method for low maintenance, low ambiguity in-situ drift velocity monitoring in large volume Time Projection Chambers (TPCs). The method was developed and deployed for the 40m^3 TPC tracker system of the NA61/SHINE experiment at CERN, which has a one meter of drift length. The method relies on a low-cost multi-wire proportional chamber placed next to the TPC to be monitored, downstream with respect to the particle flux. Reconstructed tracks in the TPC are matched to hits in the monitoring chamber, called the Geometry Reference Chamber (GRC). Relative differences in positions of hits in the GRC are used to estimate the drift velocity, removing the need for an accurate alignment of the TPC to the GRC. An important design requirement on the GRC was minimal added complexity to the existing system, in particular, compatibility with Front-End Electronics cards already used to read out the TPCs. Moreover, the GRC system was designed to operate both in large and small particle fluxes. The system is capable of monitoring the evolution of the drift velocity inside the TPC down to a one permil precision, with a few minutes of data collection.

description: Mental health professionals are in a unique position to understand the effect of social injustices on individuals and groups in society. Furthermore, counselors can intervene to disrupt injustices and promote social justice. Scholars have suggested that providing social justice training to graduate level trainees could significantly expand mental health professionals' social justice agenda to better advocate for macrolevel changes. The social justice literature provides some understanding of how to train graduate students in social justice interventions. However, little is known about a) what components of training facilitate trainees' development and b) how trainees are shaped by these practical experiences of engaging in social justice work. This study centered on how trainees develop due to their training at the Women's Resource Center (WRC) at the University of Utah, a feminist multicultural, social justice-oriented training site. A grounded theory qualitative design employed the use of interviews, focus groups, follow-up interviews, and feedback groups with prior trainees from the WRC. Of the 65 prior trainees from the WRC, 20 women participated, representing a diversity of academic training backgrounds, ethnic, religious, and socio-economic class identities. Trainees experienced three distinct and overlapping growth processes: (a) doing your own work, (b) honoring your voice and others' voices, and (c) challenging power to affect change. This growth occurred through the interaction of three tensions: (a) trainees' fit with the WRC's intentions, (b) trainees' reactions to contradictions of the WRC training, and (c) trainees' experiences external to the WRC. These tensions facilitated growth during the training year, and women who participated in the WRC training experienced continual growth, specific to: (a) maintaining their commitment, (b) building collaborative relationships in their contexts, and (c) personalizing their social justice commitment. Based on findings, implications for social justice training programs include the need to: (a) bridge theory and practice, (b) address the paradox of social justice training, (c) grow as a social justice training program, (d) provide developmentally appropriate training, and (e) prepare trainees for social justice training.

description: Soft robots are made of compliant materials and perform tasks that are challenging for rigid robots. However, their continuum nature makes it difficult to develop model-based control strategies. This work presents a robust model-based control scheme for soft continuum robots. Our dynamic model is based on the Euler-Lagrange approach, but it uses a more accurate description of the robot's inertia and does not include oversimplified assumptions. Based on this model, we introduce an adaptive sliding mode control scheme, which is robust against model parameter uncertainties and unknown input disturbances. We perform a series of experiments with a physical soft continuum arm to evaluate the effectiveness of our controller at tracking task-space trajectory under different payloads. The tracking performance of the controller is around 38\% more accurate than that of a state-of-the-art controller, i.e., the inverse dynamics method. Moreover, the proposed model-based control design is flexible and can be generalized to any continuum robotic arm with an arbitrary number of segments. With this control strategy, soft robotic object manipulation can become more accurate while remaining robust to disturbances.

Post-Translational Regulation of OCT1/POU2F1 in the Stress Response and Mitosis
Creators: name: Kang, Jinsuk
Publisher: name: University of Utah
Year: 2014

description: The Oct1/POU2F1 transcription factor was previously thought to constitutively occupy its cognate DNA binding sites, and to regulate the expression of housekeeping genes. This stereotype led to little attention being paid to Oct1 activity in dynamic cellular responses. In 2005, Oct1-/- mouse embryonic fibroblasts were shown to be highly sensitive to oxidative and genotoxic stresses, implicating Oct1 as a stress sensor. However, the mechanism connecting stress with Oct1 transcription regulation was unknown. To identify the mechanism by which Oct1 activity is regulated by posttranslational modifications in response to stress exposure, I used affinity purification and mass spectrometry to map specific Oct1 phosphorylation, O-GlcNAc modification and ubiquitination sites. Serine 385 (Chapter 2): I identified unique mechanisms of Oct1 regulation in response to stress and during mitosis, involving two different Oct1 phosphorylation events. Following genotoxic and oxidative stress, Oct1 binding specificity is mediated by phosphorylation of S385, switching from a monomeric into a dimeric conformation on different binding sequences. I confirmed this mechanism by genome wide ChIPseq. The homologous protein Oct4, a master regulator of embryonic stem cells, uses a similar mode of regulation. Serine 335 (Chapter 3): I identified an other phosphorylation event (pS335) as a negative regulator of Oct1 binding to DNA. I found that this phosphorylation is induced iv in mitotic cells as well as in stressed ones. The phosphorylated Oct1 is enriched in the mitotic spindle poles and midbody. Phospho-Oct1 is also K11-ubiquitinated. Using several different approaches, I showed that Oct1 directly regulates mitosis after being displaced from mitotic chromatin. Threonine 255 and Serine 728 (Chapter 4): In addition to phosphorylation and ubiquitination, I also identified O-GlcNAc modification of Oct1. Using an Oct1 glycosylation defective mutant, I found that the glycosylated residues of Oct1 regulate its DNA binding and transcriptional activity. Finally, I confirmed in embryonic stem cells that Oct1 and Oct4 share binding specificity for novel multimeric as well as conventional octamer motifs (Chapter 5). Further, multimeric binding motifs recruit Oct1 and Oct4 hetero-complexes suggesting extensive crosstalk between Oct1 and Oct4 in embryonic stem cells.

description: We show that observations of primordial gravitational waves of inflationary origin can shed light into the scale of flavor violation in a flavon model which also explains the mass hierarchy of fermions. The energy density stored in oscillations of the flavon field around the minimum of its potential redshifts as matter and is expected to dominate over radiation in the early universe. At the same time, the evolution of primordial gravitational waves acts as bookkeeping to understand the expansion history of the universe. Importantly, the gravitational wave spectrum is different if there is an early flavon dominated era compared to radiation domination expected from a standard cosmological model and this spectrum gets damped by the entropy released in flavon decays, determined by the mass of the flavon field $m_S$ and new scale of flavor violation $Λ_{\rm FV}$. We derive analytical expressions of the frequency above which the spectrum is damped, as-well-as the amount of damping, in terms of $m_S$ and $Λ_{\rm FV}$. We show that the damping of the gravitational wave spectrum would be detectable at BBO, DECIGO, U-DECIGO, $μ-$ARES, LISA, CE and ET detectors for $Λ_{\rm FV}=10^{5-10}$ GeV and $m_S=\mathcal{O({\rm TeV})}$. Furthermore, the flavon decays can source the baryon asymmetry of the universe. We identify the $m_S-Λ_{\rm FV}$ parameter space where the observed baryon asymmetry $η\sim 10^{-10}$ is produced and can be tested by gravitational wave detectors like LISA and ET. We also discuss our results in the context of the recently measured stochastic gravitational background signals by NANOGrav.

Mechanism and Regulation of Chromatin Remodeller, RSC

description: RSC is a multiprotein complex that remodels the structure of chromatin and in turn regulates processes like transcription. The mechanism by which RSC remodels a nucleosome is still unclear. Although bulk solution experiments have added a growing body of evidence to the mechanism by which RSC remodels a nucleosome, the mechanistic properties of the remodeler is still under debate. In this work, we have constructed a system to study the mechanistic properties of a single molecule of RSC on a naked DNA template in real time and obtain its properties like rate of translocation, processivity, force generated by the translocase and rate of ATP turnover. The SWI/SNF family of chromatin remodeling complexes contains conserved Actin-related proteins (ARPs). Genetic and biochemical evidence suggests that Sth1 might be regulated by two Actin-Related Proteins, ARP7 and ARP9. Genome wide suppressors of ARPs mapped to two domains in Sth1 called the post-HSA (Helicase/ Sant associated) domain and ATPase domain. In this work, dominant negatives of Sth1 were obtained that also localized to the post-HSA (Helicase/ Sant associated) domain. This suggests that the post-HSA domain might be involved in the regulation of Sth1. Sth1 (301-1097) construct containing the suppressor mutations co-purified with ARPs were compared for their ATPase activity and KM with wild type Sth1 (301-1097) Arps complex. The mutants showed higher ATPase activity than wild type, which was not due to their increased affinity for DNA. iv Based on the fact that the loop formed by the action of a remodeler is negatively supercoiled, in this work, we also developed an assay to assess the torsion generated by ATP dependent chromatin remodelers on naked DNA. TetR-Sth1 (301-1146) fusion co-purified with ARPs successfully produced torsion in an ATP dependent manner as assayed by this assay. This assay also depends on the action of by E. coli topoisomerase I, which specifically relaxes negative supercoils and on TetR-TetO interaction which serves to anchor the motor protein and thus constrains the loop formed by it.

description: Convolutional neural networks (CNNs) have achieved remarkable success in automatically segmenting organs or lesions on 3D medical images. Recently, vision transformer networks have exhibited exceptional performance in 2D image classification tasks. Compared with CNNs, transformer networks have an appealing advantage of extracting long-range features due to their self-attention algorithm. Therefore, we propose a CNN-Transformer combined model, called BiTr-Unet, with specific modifications for brain tumor segmentation on multi-modal MRI scans. Our BiTr-Unet achieves good performance on the BraTS2021 validation dataset with median Dice score 0.9335, 0.9304 and 0.8899, and median Hausdorff distance 2.8284, 2.2361 and 1.4142 for the whole tumor, tumor core, and enhancing tumor, respectively. On the BraTS2021 testing dataset, the corresponding results are 0.9257, 0.9350 and 0.8874 for Dice score, and 3, 2.2361 and 1.4142 for Hausdorff distance. The code is publicly available at https://github.com/JustaTinyDot/BiTr-Unet.

description: Bureaucratic rhetorics have been largely overlooked in rhetorical scholarship, in part because of an assumed synonymy between bureaucratic approaches, purposes, and language uses and political ones. This dissertation applies rhetorical analysis to a case study of bureaucratic rhetoric-the 2011 U.S. Food and Drug Administration (FDA) hearing on the breast cancer indication for the drug Avastin-to identify characteristic rhetorical strategies of bureaucracy and how these differ from the strategies of political rhetoric. In particular, I investigate the rhetorics that bureaucracies use to make sense of science in the context of regulatory decision making. Given that science is often used to support bureaucratic decisions, and that bureaucracy is involved in most aspects of scientific and medical research, the interactions between the two are of particular importance. Specifically, this project addresses three questions: (1) what are the characteristic rhetorical strategies of bureaucratic institutions; (2) who or what is the audience of bureaucratic rhetoric; and (3) what are the implications of these findings for bureaucratic institutions themselves, the public, science and medicine, and rhetorical theory? In the first part of the analysis, I investigate questions about how bureaucracy legitimizes its decisions. In the second part, I argue that one of the reasons for the disconnect between the public and the FDA is that bureaucracies, including the FDA, do not in fact address the public. Unlike political rhetorics, which address the public (and "representatives" of the public, such as lobbyists), bureaucratic rhetorics address an internal audience of the bureaucracy itself. They do so through the medium of "the record." In addressing "the record," a bureaucracy will (and the FDA does in this hearing) attempt to achieve "facticity" (the appearance or status of being taken for granted as fact) for its own desired, and often predetermined, outcomes. Thus, the primary finding of this study is that as a science-based regulatory bureaucracy, the FDA cannot allow "differences of opinion as to what the data mean."

description: We study the relaxation of a Brownian particle with long range memory under confinement in one dimension. The particle diffuses in an arbitrary confining potential and resets at random times to previously visited positions, chosen with a probability proportional to the local time spent there by the particle since the initial time. This model mimics an animal which moves erratically in its home range and returns preferentially to familiar places from time to time, as observed in nature. The steady state density of the position is given by the equilibrium Gibbs-Boltzmann distribution, as in standard diffusion, while the transient part of the density can be obtained through a mapping of the Fokker-Planck equation of the process to a Schrödinger eigenvalue problem. Due to memory, the approach at late times toward the steady state is critically self-organised, in the sense that it always follows a sluggish power-law form, in contrast to the exponential decay that characterises Markov processes. The exponent of this power-law depends in a simple way on the resetting rate and on the leading relaxation rate of the Brownian particle in the absence of resetting. We apply these findings to several exactly solvable examples, such as the harmonic, V-shaped and box potentials.
