The Politics of Hysteria in David Cronenberg's "The Brood"
Creators: name: Averett, Kate
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: This thesis situates David Cronenberg’s 1979 film The Brood within the politics of family during the late 1970s by examining the role of monstrous birth as a form of hysteria. Specifically, I analyze Cronenberg’s monstrous Mother, Nola Carveth, within the role of the family in the 1970s, when the patriarchal, nuclear family is under question in American society. In his essay The American Nightmare: Horror in the 70s critic Robin Wood began a debate surrounding Cronenberg’s early films, namely accusing the director of reactionary misogyny and calling for a political critique of his and other horror director’s work. The debate which followed has sidestepped The Brood, disregarding it as a complication to his oeuvre due to its autobiographical basis. This film, however, offers an opportunity to apply Wood’s call for political criticism to portrayals of hysteria in contemporary visual culture; this thesis takes up this call and fills an important interpretive gap in the scholarship surrounding gender in Cronenberg’s early films.

description: The ATHENA project is funded by the European Commission (EC) under the topic of the Science with and for Society work programme SwafS-09-2018-2019-2020 ‘Supporting research organisations to implement gender equality plans’. ATHENA overall aims at supporting the development and implementation of Gender Equality Plans (GEPs) in 6 research performing organisations (RPOs) and 2 research funding organisations (RFOs) in Europe. To that purpose, Work Package (WP) 6 (named ‘Sustainability strategy to ensure replication of GEPs and project results’) includes a specific task (T6.3) titled ‘Creation and maintenance of a web-based community platform with all project results and tools’, whose aim is to host the materials and tools developed by the project at the same time as serving as a repository for identification of women researchers at EU level and a place for information and experiences exchange on GEPs and gender equality in science and research. The ‘ATHENA e-platform for action’ is the result of this task, led by the Spanish SME Consulta Europa Projects and Innovation S.L (short name, Consulta Europa). Consulta Europa developed the e-platform and included modifications and improvements based on comments received from the project consortium.

description: In den histopathologischen Mustern III und IV nach Lucchinetti et al. 2000 ist die Anzahl der Oligodendrozyten in MS-Läsionen deutlich reduziert. Zugleich findet man in diesen Subtypen eine vermehrte Expression von p53. Daher war es Ziel der vorliegenden Arbeit zu untersuchen, ob das vermehrte Vorkommen von Sequenzveränderungen im p53-Gen ursächlich für die vermehrte p53-Expression in Oligodendrozyten der MS-Plaques sein könnte. Dazu wurden DNA-Proben von MS-Patienten und gesunden Kontrollen mittels PCR-SSCP untersucht, verglichen und ggf. sequenziert. Dabei fand sich mit Hilfe der angewendeten Methoden kein signifikanter Unterschied zwischen beiden Kollektiven. Die Ergebnisse der vorliegenden Arbeit geben nichtsdestotrotz Anlass zu vermuten, dass p53 in einigen histologischen Subtypen der MS - in welcher Form auch immer - an der Pathogenese oder dem Untergang von Oligodendrozyten in MS-Läsionen beteiligt zu sein scheint. Die gefundene erhöhte Expression ist in ihrer Ätiologie bislang noch nicht geklärt. Dennoch könnten weitere Untersuchungen p53-abhängiger Mechanismen, die zu einer Zerstörung von Myelin/Oligodendrozyten führen, einen Beitrag zur Entwicklung neuer Therapiestrategien leisten. Sowohl neue immunmodulatorische als auch neuroprotektive Therapien erscheinen in diesem Zusammenhang denkbar.
description: Clinical course, outcome, radiological features, severity, and histopathology are heterogenous in multiple sclerosis (MS). Since MS is considered to be a polygenic disease, the genetic background may at least partly be responsible for this variability. Some MS cases are histopathologically characterized by a dramatic oligodendrocyte loss that is in part caused by apoptosis. A dysregulated apoptotic elimination of self-reactive T cells may also contribute to disease susceptibility. To analyze genetic differences in the apoptosis regulating factors p53 we investigated polymorphisms of these gene in 105 patients with a relapsing remitting disease course, 49 patients with a primary progressive course and 100 controls by PCR-SSCP and direct sequencing. We identified so far unpublished sequence alterations in the promotor region of the in exon 7 of the p53 gene.. No differences were observed between MS patients and controls. Additional known polymorphisms were found in exon 6 of the p53 gene. No significant differences in the frequency of gene sequence variations were found between MS patients and controls. The apoptosis gene studied here therefore appear less likely to be important effector genes in MS.

Bayesian Semiparametric Methods for Longitudinal, Multivariate, and Survival Data
Creators: name: Pennell, Michael Lindsey
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: In many biomedical studies, the observed data may violate the assumptions of standard parametric methods. In these situations, Bayesian methods are appealing since nonparametric priors, such as the Dirichlet process (DP), can incorporate a priori knowledge regarding the shape or location of an unknown distribution and exact inferences are available using Markov chain Monte Carlo methods. Despite the promise of Bayesian nonparametric methods, computation can be difficult under large sample sizes. In addition, there is a paucity of methods for multiple event time data and for testing across multiple groups. In this dissertation, we propose three methods which address important computational, modelling, and testing issues in Bayesian nonparametrics. Our first method is a computationally simple approach to fitting Bayesian semiparametric random effects models to large longitudinal data sets. Our approach involves fitting a model to a smaller set of pseudo-data, which is constructed using expert opinion. The research was motivated by data from the Collaborative Perinatal Project, which was a prospective epidemiology study consisting of over 30,000 children. We next develop a dynamic frailty model which accounts for age-dependent changes in susceptibility to a repeated health event, such as the occurrence of new tumors. Our model generalizes the traditional shared frailty model for multiple event time data to accommodate smooth, time dependent trends in the frailty, baseline hazard, and covariate effects. We also relax our assumptions on the frailty using DP priors. Lastly, we present a Bayesian nonparametric method for testing for changes in a response distribution with an ordinal predictor. The research was motivated by data from toxicology studies, in which dose may affect both the shape and location of the response distribution. Using a generalization of the dynamic mixture of DPs (Dunson, 2006, Biostatistics, to appear), we test for equivalence in the unknown distribution across dose groups and estimate threshold doses. Our method accommodates multivariate responses without complication.

description: Machine learning models have demonstrated vulnerability to adversarial attacks, more specifically misclassification of adversarial examples. In this paper, we investigate an attack-agnostic defense against adversarial attacks on high-resolution images by detecting suspicious inputs. The intuition behind our approach is that the essential characteristics of a normal image are generally consistent with non-essential style transformations, e.g., slightly changing the facial expression of human portraits. In contrast, adversarial examples are generally sensitive to such transformations. In our approach to detect adversarial instances, we propose an in\underline{V}ertible \underline{A}utoencoder based on the \underline{S}tyleGAN2 generator via \underline{A}dversarial training (VASA) to inverse images to disentangled latent codes that reveal hierarchical styles. We then build a set of edited copies with non-essential style transformations by performing latent shifting and reconstruction, based on the correspondences between latent codes and style transformations. The classification-based consistency of these edited copies is used to distinguish adversarial instances.

description: Given a complex curve C of genus 2, there is a well-known relationship between the moduli space of rank 3 semistable bundles on C and a cubic hypersurface known as the Coble cubic. Some of the aspects of this is known to be related to the geometric invariant theory of the third exterior power of a 9-dimensional complex vector space. We extend this relationship to arbitrary fields and study some of the connections to invariant theory, which will be studied more in-depth in a followup paper.

A Mixed-Methods Exploration of Stereotype Threat in Middle Childhood

Subjects: Social service

description: The three studies presented in this dissertation were designed to develop a mixed-methods foundation for the extension of stereotype threat research to a middle childhood (ages 6-11; Centers for Disease Control and Prevention, 2012) population. The first paper systematically reviews existing research on stereotype threat among children to evaluate evidence that stereotype threat affects the learning and performance of children in middle childhood and to compare and contrast features of stereotype threat in children with features of the phenomenon identified in research involving older populations. The second paper focuses on two constructs identified in the systematic review as potential buffers of stereotype threat in middle childhood: social support and school belonging. Because the study of stereotype threat inherently involves comparison of students belonging to different social groups, measures of constructs related to stereotype threat must support accurate cross-group comparisons. The purpose of the second paper is to determine whether an existing measurement tool assessing school belonging and social support (the Elementary School Success Profile for Children) performs equally for both Black/African American and White children, and can be used to make valid cross-group comparisons on levels of these constructs. Although Paper 2 contributes to solving some of the measurement issues related to stereotype threat in middle childhood by validating a measure of constructs believed to buffer stereotype threat, no direct measure of stereotype threat currently exists. Development of such a measure would require exploratory qualitative work to learn more about the nature of stereotype threat in middle childhood. The third paper of this dissertation uses vignette methodology to explore how children in the target age group perceive and experience stereotype threat. Children responded to six vignettes modeling Shapiro and Neuberg's Multithreat Framework (2007), discussing their thoughts on the ostensibly stereotype threatening situations as well as their perceptions of conditions contributing to threats and the consequences associated with threat experiences. Paper 3 presents children's perspectives on stereotype threat in their own words, while framing the responses in the contexts of existing stereotype threat research and knowledge of child development.
Superconductivity driven by pairing of the coherent parts of the physical electrons

description: How the superconductivity in unconventional superconductors emerges from the diverse mother normal states is still a big puzzle. Whatever the mother normal states are the superconductivity is {\em normal} with BCS-like behaviours of the paired quasiparticles in condensation. To reconcile the diverse mother normal states and the normal superconductivity in unconventional superconductors, we revisit a proposal that the emergence of the low-energy coherent parts of the physical electrons, which survive from the interaction correlations, is an essential prerequisite for superconductivity. The superconductivity is driven by the pair condensation of these coherent parts of the physical electrons. Moreover the incoherent parts of the physical electrons can enhance the superconducting transition temperature $T_c$ although they are not in driving role in the emergence of the superconductivity. Some experimental responses of the coherent parts of the physical electrons are predicted.

The Effect of Football Shoulder Pad Removal Technique and Equipment Removal Training on Cervical Spine Motion, Time to Task Completion, and Perceived Task Difficulty
Creators: name: Lenhardt, Catherine Shawn
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: Current recommendations for management of cervical spine injury suggest leaving football equipment in place unless otherwise indicated by the NATA position statement. We investigated the effect of three shoulder pad removal techniques and the effect of reinforced training on cervical spine motion, time, and difficulty. The RipKord shoulder pads were faster than both traditional shoulder pad removal techniques (P<0.001) and easier (P<0.05) than the flat torso to remove. Less cervical spine range of motion with the flat torso technique was observed in the sagittal and frontal planes (P<0.05) during Testing Session II in the reinforced training group. Both traditional shoulder pad removal techniques were faster during Session II [flat (P=0.001); elevated (P<0.001)]. The RipKord shoulder pads provided a method for removal with superior measure of time and difficulty compared with traditional removal techniques. With reinforced training, cervical spine motion improved with the flat torso technique.

description: We consider a stationary spherically symmetric monopole like solution with a finite energy density in a pure quantum chromodynamics (QCD). The solution can be treated as a static Wu-Yang monopole dressed in time dependent field corresponding to off-diagonal gluons. We have proved that such a stationary monopole field represents a background vacuum field of the QCD effective action which is stable against quantum gluon fluctuations. This resolves a long-standing problem of existence of a stable vacuum field in QCD and opens a new avenue towards microscopic theory of the vacuum.

description: Charge migration is the electronic response that immediately follows localized ionization or excitation in a molecule, before the nuclei have time to move. It typically unfolds on sub-femtosecond time scales and most often corresponds to dynamics far from equilibrium, involving multi-electron interactions in a complex chemical environment. While charge migration has been documented experimentally and theoretically in multiple organic and inorganic compounds, the general mechanism that regulates it remains unsettled. In this work we use tools from nonlinear dynamics to analyze charge migration that takes place along the backbone of conjugated hydrocarbons, which we simulate using time-dependent density functional theory. In this electron-density framework we show that charge migration modes emerge as attosecond solitons and demonstrate the same type of solitary-wave dynamics in both simplified model systems and full three-dimensional molecular simulations. We show that these attosecond-soliton modes result from a balance between dispersion and nonlinear effects tied to time-dependent multi-electron interactions.%Our soliton-mode mechanism, and the nonlinear tools we use to analyze it, pave the way for understanding migration dynamics in a broad range of organic molecules.%For instance, we demonstrate the opportunities for chemically steering charge migration via molecular functionalization, which can alter both the initially localized electron perturbation and its subsequent time evolution.

description: We reanalyze the dataset collected during the years 1998--2003 by the deep underwater neutrino telescope NT200 in the lake Baikal with the low energy threshold (10 GeV) in searches for neutrino signal from dark matter annihilations near the center of the Milky Way. Two different approaches are used in the present analysis: counting events in the cones around the direction towards the Galactic Center and the maximum likelihood method. We assume that the dark matter particles annihilate dominantly over one of the annihilation channels $b\bar{b}$, $W^+W^-$, $τ^+τ^-$, $μ^+μ^-$ or $ν\barν$. No significant excess of events towards the Galactic Center over expected neutrino background of atmospheric origin is found and we derive 90% CL upper limits on the annihilation cross section of dark matter.

REAL-TIME SCHEDULING ON ASYMMETRIC MULTIPROCESSOR PLATFORMS
Creators: name: Yang, Kecheng
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Real-time scheduling analysis is crucial for time-critical systems, in which provable timing guarantees are more important than observed raw performance. Techniques for real-time scheduling analysis initially targeted uniprocessor platforms but have since evolved to encompass multiprocessor platforms. However, work directed at multiprocessors has largely focused on symmetric platforms, in which every processor is identical. Today, it is common for a multiprocessor to include heterogeneous processing elements, as this offers advantages with respect to size, weight, and power (SWaP) limitations. As a result, realizing modern real-time systems on asymmetric multiprocessor platforms is an inevitable trend. Unfortunately, principles and mechanisms regarding real-time scheduling on such platforms are relatively lacking.
      The goal of this dissertation is to enrich such principles and mechanisms, by bridging existing analysis for symmetric multiprocessor platforms to asymmetric ones and by developing new techniques that are unique for asymmetric multiprocessor platforms. The specific contributions are threefold.
      First, for a platform consisting of processors that differ with respect to processing speeds only, this dissertation shows that the preemptive global earliest-deadline-first (G-EDF) scheduler is optimal for scheduling soft real-time (SRT) task systems. Furthermore, it shows that semi-partitioned scheduling, which is a hybrid of conventional global and partitioned scheduling approaches, can be applied to optimally schedule both hard real-time (HRT) and SRT task systems.
      Second, on platforms that consist of processors with different functionalities, tasks that belong to different functionalities may process the same source data consecutively and therefore have producer/consumer relationships among them, which are represented by directed acyclic graphs (DAGs). End-to-end response-time bounds for such DAGs are derived in this dissertation under a G-EDF-based scheduling approach, and it is shown that such bounds can be improved by a linear-programming-based deadline-setting technique.
      Third, processor virtualization can lead a symmetric physical platform to be asymmetric. In fact, for a designated virtual-platform capacity, there exist an infinite number of allocation schemes for virtual processors and a choice must be made. In this dissertation, a particular asymmetric virtual-processor allocation scheme, called minimum-parallelism (MP) form, is shown to dominate all other schemes including symmetric ones.

description: The spin resonance of electrons can be coupled to a microwave cavity mode to obtain a photon-magnon hybrid system. These quantum systems are widely studied for both fundamental physics and technological quantum applications. In this article, the behavior of a large number of ferrimagnetic spheres coupled to a single cavity is put under test. We use second-quantization modeling of harmonic oscillators to theoretically describe our experimental setup and understand the influence of several parameters. The magnon-polariton dispersion relation is used to characterize the system, with a particular focus on the vacuum Rabi mode splitting due to multiple spheres. We combine the results obtained with simple hybrid systems to analyze the behavior of a more complex one, and show that it can be devised in such a way to minimize the degrees of freedom needed to completely describe it. By studying single-sphere coupling two possible size-effects related to the sample diameter have been identified, while multiple-spheres configurations reveal how to upscale the system. This characterization is useful for the implementation of an axion-to-electromagnetic field transducer in a ferromagnetic haloscope for dark matter searches. Our dedicated setup, consisting in ten 2 mm-diameter YIG spheres coupled to a copper microwave cavity, is used for this aim and studied at mK temperatures. Moreover, we show that novel applications of optimally-controlled hybrid systems can be foreseen for setups embedding a large number of samples.

Expanding Neurochemical Methods: Improved Drug Delivery and Multi-Modal Recording
Creators: name: Kirkpatrick, Douglas
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Neurochemical systems are studied by a variety of techniques in order to reveal information about physiological events such as cell firing, chemical changes, and vasoactivity. The aim of this dissertation is to improve upon the characterization ability of several existing methods through instrumental optimization and experimental design. First, microiontophoresis, a qualitative drug delivery technique which uses an electric current to eject drugs from a micropipette, is investigated for its quantitative capabilities. Factors underlying the volume affected by ejections and the concentration distribution of ejected species are determined. Next, the drug delivery rate during ejection from the micropipette is examined under a variety of conditions. From this, it is shown how the delivery rate can be modulated using the iontophoretic current and the concentration of the ejection solution. Further, controlled iontophoresis, which uses a carbon-fiber microelectrode to detect ejected electroactive species, is employed in an attempt to directly measure concentrations from ejections. To determine the accuracy, neurochemical responses following iontophoretic drug delivery are compared to responses from known drug concentrations. These studies reveal how systemic errors in ejection protocols can lead to inaccurate concentration evaluations. Practical experimental solutions to overcome these limitations are presented, and when instituted, lead to more accurate measurements. Lastly, a multi-modal recording method is demonstrated which combines patch clamp electrophysiology and FSCV measurements in a brain slice. This is instituted with iontophoresis to provide a new way to simultaneously monitor cell behavior and chemical changes during drug delivery. In all, this work demonstrates how improvements in analytical methodologies can increase the power and scope of neurochemical investigations.

description: This paper reviews the current state of the art in Artificial Intelligence (AI) technologies and applications in the context of the creative industries. A brief background of AI, and specifically Machine Learning (ML) algorithms, is provided including Convolutional Neural Network (CNNs), Generative Adversarial Networks (GANs), Recurrent Neural Networks (RNNs) and Deep Reinforcement Learning (DRL). We categorise creative applications into five groups related to how AI technologies are used: i) content creation, ii) information analysis, iii) content enhancement and post production workflows, iv) information extraction and enhancement, and v) data compression. We critically examine the successes and limitations of this rapidly advancing technology in each of these areas. We further differentiate between the use of AI as a creative tool and its potential as a creator in its own right. We foresee that, in the near future, machine learning-based AI will be adopted widely as a tool or collaborative assistant for creativity. In contrast, we observe that the successes of machine learning in domains with fewer constraints, where AI is the `creator', remain modest. The potential of AI (or its developers) to win awards for its original creations in competition with human creatives is also limited, based on contemporary technologies. We therefore conclude that, in the context of creative industries, maximum benefit from AI will be derived where its focus is human centric -- where it is designed to augment, rather than replace, human creativity.

description: We study a holographic construction of quantum rotating BTZ black holes that incorporates the exact backreaction from strongly coupled quantum conformal fields. It is based on an exact four-dimensional solution for a black hole localized on a brane in AdS$_4$, first discussed some years ago but never fully investigated in this manner. Besides quantum CFT effects and their backreaction, we also investigate the role of higher-curvature corrections in the effective three-dimensional theory. We obtain the quantum-corrected geometry and the renormalized stress tensor. We show that the quantum black hole entropy, which includes the entanglement of the fields outside the horizon, satisfies the first law of thermodynamics exactly, even in the presence of backreaction and with higher-curvature corrections, while the Bekenstein-Hawking-Wald entropy does not. This result, which involves a rather non-trivial bulk calculation, shows the consistency of the holographic interpretation of braneworlds. We compare our renormalized stress tensor to results derived for free conformal fields, and for a previous holographic construction without backreaction effects, which is shown to be a limit of the solutions in this article.

description: In this paper we consider multidimensional stochastic differential equations (SDEs) with discontinuous drift and possibly degenerate diffusion coefficient. We prove an existence and uniqueness result for this class of SDEs and we present a numerical method that converges with strong order 1/2. Our result is the first one that shows strong convergence for such a general class of SDEs. The proof is based on a transformation technique that removes the discontinuity from the drift such that the coefficients of the transformed SDE are Lipschitz continuous. Thus the Euler-Maruyama method can be applied to this transformed SDE. The approximation can be transformed back, giving an approximation to the solution of the original SDE. As an illustration, we apply our result to an SDE the drift of which has a discontinuity along the unit circle.
Combined search for anomalous pseudoscalar HVV couplings in VH production and H to VV decay

description: A search for anomalous pseudoscalar couplings of the Higgs boson H to electroweak vector bosons V (= W or Z) in a sample of proton-proton collision events corresponding to an integrated luminosity of 18.9 inverse femtobarns at a center-of-mass energy of 8 TeV is presented. Events consistent with the topology of associated VH production, where the Higgs boson decays to a pair of bottom quarks and the vector boson decays leptonically, are analyzed. The consistency of data with a potential pseudoscalar contribution to the HVV interaction, expressed by the effective pseudoscalar cross section fractions f[a3], is assessed by means of profile likelihood scans. Results are given for the VH channels alone and for a combined analysis of the VH and previously published H to VV channels. Under certain assumptions, f[a3](ZZ) > 0.0034 is excluded at 95% confidence level in the combination. Scenarios in which these assumptions are relaxed are also considered.

Quantifying frequency and variety of activities in older adults: relationships with physical and cognitive performance
Creators: name: Shubert, Tiffany Elisa
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Activity provides a protective effect against cognitive and physical decline in older adults. Recent literature suggests that for older adults, variety and frequency of activity may be more important to this protective effect than intensity level. Although the ideal amount, type, and intensity of activity for preventing decline has not been determined, current tools for measuring activity are inadequate. A review of current activity measures used for older adults revealed that there is no reliable and valid tool to quantify variety or frequency of participation in different types of activities. Using a cross sectional design, I developed, tested and validated the Variety of Activity Questionnaire (VAQ) to measure frequency and variety in social, cognitive, physical, and exercise activity domains, and examined associations among frequency and variety with physical and cognitive function. Questionnaires were collected from 196 community dwelling older adults (range: 70 - 99 years, mean: 78.7 years) in North Carolina. Exploratory factor analysis evaluated the underlying structure of the VAQ. An ICC was used to assess test-retest reliability for the outcomes of total activity (TA) and variety of activity (VA) on a subset of 30 participants and construct validity on a different subset of 53 participants. Physical and cognitive performance measures were assessed on 95 participants. Regression analyses identified demographic and performance measures significantly associated with TA and VA. The VAQ demonstrated acceptable test-retest reliability [ICC 2,1 = .69 (TA), .72 (VA)] and validity [ICC 2,1 = .57(TA), .71(VA)]. The VAQ failed to factor; therefore, the structure and components of the VAQ were not modified. A mobility measure and marital status were significant predictors of VA, and a dynamic balance measure was a significant predictor of TA. Measures of attention and processing speed were significantly related to both VA and TA, but had stronger associations with VA. Variety of activity appears to have stronger associations with physical and cognitive performance than TA, suggesting that variety of activity may be important for function. The VAQ has potential as a tool for researchers and clinicians and warrants continued study. Future intervention studies will clarify the relationship between variety of activity and function.
Mosco convergence for H(curl) spaces, higher integrability for Maxwell's equations, and stability in direct and inverse EM scattering problems

description: This paper is concerned with the scattering problem for time-harmonic electromagnetic waves, due to the presence of scatterers and of inhomogeneities in the medium. We prove a sharp stability result for the solutions to the direct electromagnetic scattering problem, with respect to variations of the scatterer and of the inhomogeneity, under minimal regularity assumptions for both of them. The stability result leads to uniform bounds on solutions to the scattering problems for an extremely general class of admissible scatterers and inhomogeneities. The uniform bounds are a key step to tackle the challenging stability issue for the corresponding inverse electromagnetic scattering problem. In this paper we establish two optimal stability results of logarithmic type for the determination of polyhedral scatterers by a minimal number of electromagnetic scattering measurements. In order to prove the stability result for the direct electromagnetic scattering problem, we study two fundamental issues in the theory of Maxwell equations: Mosco convergence for H(curl) spaces and higher integrability properties of solutions to Maxwell equations in nonsmooth domains.

Educator perspectives on school counselor advocacy as it relates to the college access of underrepresented students
Creators: name: Schaeffer, Kelly

description: Research indicates that minority students, economically disadvantaged students, and first-generation students are underrepresented in four-year colleges and universities. Literature encourages school counselors to act as advocates in their schools while addressing issues of inequity which include the college access of underrepresented groups of students. The purpose of this qualitative study was to explore the practice of high school counselor advocacy as it relates specifically to increasing access for students traditionally underrepresented in four-year colleges and universities. While theoretical literature encourages the practice of advocacy in schools, little research has been conducted that examines school counselor advocacy within this context. Twelve school counselors, three school administrators, and four mathematics teachers were interviewed regarding their perspectives on school counselor advocacy. The initial presentation of the data utilized the research questions along with the Advocacy Competencies for Professional School Counselors. The research questions defined advocacy, described advocacy behaviors, and identified factors that impact the use of advocacy within this context. In addition, the advocacy competencies of dispositions, knowledge, and skills were utilized to gain a deeper understanding of the data. Participants defined advocacy by emphasizing the importance of empathy, a parental role, and an ethical disposition. Advocacy behaviors that were described included utilizing the two-year college, along with the skills of communication, collaboration, the use of data, family empowerment, and systemic change. Finally, the participants identified relevant advocacy factors such as the school counselor's background, school counselor complacency, student ability, family barriers, role confusion, and district and state barriers. Context was identified as a necessary addition to the advocacy competencies. School counselor advocacy was also examined within the context of the current state of education. Recommendations include the recruitment of potential school counselors that possess a disposition for advocacy and leadership along with graduate education and professional development in these areas. In addition, practicing school counselors can develop comprehensive school counseling programs that emphasize advocacy and equity for all students while promoting college access for underrepresented groups of students.
