Evaluating histologic grading systems and the expression of human cytomegalovirus in salivary gland mucoepidermoid carcinoma
Creators: name: Malinchoc, Sasha
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Mucoepidermoid carcinoma (sMEC) is the most common salivary gland malignancy. Traditionally, these tumors are histologically graded using point-based systems. Accurate grading is needed to guide treatment; however, current systems are criticized as inconsistent and cumbersome. The finding of human cytomegalovirus (hCMV) as causative to the development of sMEC suggests viral activity may influence tumor grade. Twenty-three sMEC specimens were independently graded by two oral pathologists and one oral pathology resident using both the Armed Forces Institute of Pathology (AFIP) and Brandwein methods. Inter-observer agreement and predictive value to patient outcome were statistically analyzed. sMEC specimens were then immunohistochemically evaluated using antibodies to two different hCMV proteins. Higher inter-observer agreement was observed with the AFIP grading method. Statistical significance was not achieved to assess the predictive value of either grading system. Detection of hCMV was negative with one of the antibodies used, while the other was equivocal.

description: The recent discovery of the first Weyl semimetal in TaAs provides the first observation of a Weyl fermion in nature. Such a topological semimetal features a novel type of anomalous surface state, the Fermi arc, which connects a pair of Weyl nodes through the boundary of the crystal. Here, we present theoretical calculations of the quasi-particle interference (QPI) patterns that arise from the surface states including the topological Fermi arcs in the Weyl semimetals TaAs and NbP. Most importantly, we discover that the QPI exhibits termination-points that are fingerprints of the Weyl nodes in the interference pattern. Our results, for the first time, propose an interference signature of the topological Fermi arcs in TaAs, which provides important guidelines for STM measurements on this prototypical Weyl semimetal compound. The scattering channels presented here is relevant to transport phenomena on the surface of the TaAs class of Weyl semimetals. Our work is also the first systematic calculation of the quantum interferences from the Fermi arc surface states, which is in general useful for future STM studies on other Weyl semimetals.

The europeanization of minority rights policy: the Hungarian and Latvian examples
Creators: name: Wilson, Casey
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: The twentieth century has witnessed some of the most violent and extreme 'policies of elimination' towards minorities in the region of Central and Eastern Europe. However, it has also witnessed two major pan-European attempts towards tolerance and promotion of minority rights - one being the failed interwar League of Nations system and the other being the contemporary post-Cold War norms of the European Union, the Organization for Security and Cooperation in Europe (OSCE), and the Council of Europe. The purpose of this thesis is to examine this 'europeanization' of minority rights by specifically looking at its recent implementation and impact on minority rights issues in two Central and Eastern European countries with very different 'minority situations': Hungary and Latvia. What are the successes and limitations? How successful have these policies actually been in practice and will this positive trend last or has the leverage behind membership in Western institutions lost momentum now that these countries have become members? These are all questions I will address. By specifically looking at the case of Hungary, I will also argue that changes at the national level played an important role as a precondition for successful EU minority rights policy implementation. Alternatively, in discussing Latvia I intend to argue the opposite to be true - which is that in this specific case it was the requirement of EU minority rights policy adoption into national legislation that affected changes at the national level.

description: Federation of Finnish Learned Societies and IT Center for Science have published open data on monitoring the implementation of open science policies in Finnish universities and research organisations. This talk introduces the monitoring results in the context of Universities of Applied Sciences in Finland (UAS).

 The monitoring revealed that Finnish UASs are committed to the Declaration of Open Science and Research and have worked to promote open science practices in national and organisational level. The monitoring was based on various indicators and survey targeted to research organisations. A five-level model to determine the degree of openness (1-5) was created based on the key indicators and the number of points given.

 In overall assessments of openness 39% of UAS were on the highest level (level 5) and 39% on the level 4, only three organisations were on the level 3 and two on level 2. Besides that, organisational open science and research profile – a set of organisational degrees of openness was calculated based on open science and research indicators in four areas: culture for open scholarship, open access to scholarly publications, open access of research data and methods, and open education and open access to educational resources.

description: Active stabilization in systems with zero or negative stiffness is an essential element of a wide variety of biological processes. We study a prototypical example of this phenomenon at a micro-scale and show how active rigidity, interpreted as a formation of a pseudo-well in the effective energy landscape, can be generated in an overdamped ratchet-type stochastic system. We link the transition from negative to positive rigidity with correlations in the noise and show that subtle differences in out-of-equilibrium driving may compromise the emergence of a pseudo-well.

The Great Tapestry Of Scotland. Konstruktion nationaler Identität mit Nadel und Faden

Publisher: name: FKW // Zeitschrift für Geschlechterforschung und visuelle Kultur
Year: 2020

description: In Great Britain, a region traditionally associated with needlework, a special phenomenon of commemorative embroidery projects aiming to visualize history has emerged around the turn of the millennium. This paper focuses on one of these projects, The Great Tapestry of Scotland (2012–2013), a large-scale tapestry of 160 individual panels, hand-embroidered by over 1000 stitchers. Its topic is the history of Scotland beginning with the tectonic formation of the British Isles and ending with events close to its manufacturing date. However, in contrast to depicting a political national history concentrating on wars and battles the panels primarily follow people’s lives through the centuries. Providing the first art-historical analysis of this piece, this paper asks how and why collaborative embroidery is used to depict this particular version of Scottish history. In doing so, it pays special attention to the meta-textile framing of the shown scenery.

Protest im Fast Fashion-Alltag. Visible Mending als textile Intervention
Creators: name: Derwanz, Heike
Publisher: name: FKW // Zeitschrift für Geschlechterforschung und visuelle Kultur
Year: 2020

description: Visible Mending is the inversion of the practice of invisible clothing repair through mending and darning and appeared first in the internet and lately in books. Visible Mending celebrates old household practices as an environmentally friendly alternative in the age of fast fashion (Rodabaugh 2018; Wilding Cardon 2018). It appears as art in galleries or museums or as activism in the form of political consumerism. Described as a way to slow down fast fashion (Clark 2008; Fletcher 2012), its purpose as art or everyday object is to display the aesthetics of aging clothing and the agency of consumers. The article presents artworks and practices from a historical class and gender perspective to understand todays meanings as artistic or activist intervention in everyday life.

description: Embroidery seen as feminine handicraft and housework seems to be out of date. Since the 1990s an opposing trend is obviously true for contemporary art, where embroidery celebrates a convincing revival in performance art and public art practice. In particular women artists experiment with new materials and techniques to explore the art of stitching as critical strategy. Working outside the gallery and occupying public space, these artists confront the viewer with a counter-practice of textile intervention. But how to describe the subversive potential of these works appropriating a traditional needlework? I will focus my discussion on the project SOLANGE by Katharina Cibulka to discuss the aesthetic, spatial and discursive strategies that inform her art practice as feminist practice. Additionally, I refer to recent transformations in the political discourse of feminist art, including the concept of collectivity in contemporary art

description: Using particle-scale simulations of non-suspended sediment transport for a large range of Newtonian fluids driving transport, including air and water, we determine the bulk transport cessation threshold $Θ^r_t$ by extrapolating the transport load as a function of the dimensionless fluid shear stress (`Shields number') $Θ$ to the vanishing transport limit. In this limit, the simulated steady states of continuous transport can be described by simple analytical model equations relating the average transport layer properties to the law of the wall flow velocity profile. We use this model to calculate $Θ^r_t$ for arbitrary environments and derive a general Shields-like threshold diagram in which a Stokes-like number replaces the particle Reynolds number. Despite the simplicity of our hydrodynamic description, the predicted cessation threshold, both from the simulations and analytical model, quantitatively agrees with measurements for transport in air and viscous and turbulent liquids despite not being fitted to these measurements. We interpret the analytical model as a description of a continuous rebound motion of transported particles and thus $Θ^r_t$ as the minimal fluid shear stress needed to compensate the average energy loss of transported particles during an average rebound at the bed surface. This interpretation, supported by simulations near $Θ^r_t$, implies that entrainment mechanisms are needed to sustain transport above $Θ^r_t$. While entrainment by turbulent events sustains intermittent transport, entrainment by particle-bed impacts sustains continuous transport. Combining our interpretations with the critical energy criterion for incipient motion by Valyrakis and coworkers, we put forward a new conceptual picture of sediment transport intermittency.
Queering the Kanga. Spekulatives Gewebe in Kawira Mwirichias To Revolutionary Type Love

description: Kenyan artist Kawira Mwirichia startet her project with the title To Revolutionary Type Love in 2016 and plans to finish it in 2020: By then, the series will present one kanga honoring the queer movement of each nation of the world. A kanga is a traditional cloth in East African countries, where homosexuality is criminalized – so using the form and look of a kanga is a political as well as artistic appropriation, bringing the topic of queer love and human rights if not into the everyday openly, so at least into the public space of art places. As the history of the kanga itself is a history of appropriating the Portuguese (colonial) textile for East African’s Swahili women’s culture at the end of the 19th century, Mwirichia’s kanga designs not only link the present to this chapter of the colonial past, but also use her “speculative design“ to relate to a possible future, where revolutionary love will have its space.

Textil transportiert. Gülsün Karamustafas Courier als Verhandlungsort politischer Sichtbarkeit
Creators: name: Korfmacher, Friederike

Year: 2020

description: With Courier (1991) the Turkish artist Gülsün Karamustafa created a textile work of art, that gives the possibility of acknowledging visibility in the field of migration. The visibility of migration is a sensitive issue, induced by medial representation and the caused connotation of the other. In the field of art one chance of breaking with this handed down views is the use of textiles. The understanding of the material as a medium of memory, constitutes its function as a surrogate for the human body – approachable for a variety of viewers, due to their own experience of the material. Through this mechanism, the visualization of migrants without explicit representation of bodies opens the possibility of identification and thus appreciation. On this basis, Karamustafa’s work further develops the image of an active individual, appropriating the subversive historico-cultural technique of stitching. A crucial strength of the artwork develops from its immanent oscillation between historical depth and associative openness in the present.

description: Several systematic review and meta-analyses (SRMA) of randomized controlled trials (RCT) have been conducted to investigate the effects of L-carnitine supplementation in patients with end-stage kidney disease. However, here is no comprehensive umbrella review of the estimates of effects for L-carnitine with trial data, including the certainty of evidence for each estimate and the magnitude of the observed effect based on the minimal clinically important difference. We will perform an umbrella review of SRMA of RCTs on the effects of supplementations with L-carnitine on health-related outcomes in patients with end-stage kidney disease requiring hemodialysis.
Feminist In-Action. Ingrid Wiener’s Tapestry Collaborations
Creators: name: Schopp, Caroline Lillian
Publisher: name: FKW // Zeitschrift für Geschlechterforschung und visuelle Kultur
Year: 2020

description: There is a tendency in recent art history to see artistic practice as aligning with political activism, and artists who are women as making feminist art. VALIE EXPORT, the paradigmatic “woman artist” in this regard, encapsulated this position in her formulation of Feminist Actionism. This paper draws out a complementary tendency exhibited in the work of Ingrid Wiener that I call feminist in-action. In contrast with the confrontational practices of many of her contemporaries, Wiener’s tapestry collaborations with Dieter Roth present long-drawn-out performances of withdrawal. Her weaving explores a relational and dependent view of both artistic practice and the self. Refusing the feminist-actionist’s arsenal of assertive gestures, Wiener picks apart the conventions of highwarp Gobelins tapestry weaving in order to attend to an immanent and intimate, sometimes frayed, sometimes touching, space of correspondence. Wiener’s tapestry collaborations with Roth thus articulate an alternative textile politics as a politics of care.

description: In this paper, the application of simultaneous wireless information and power transfer (SWIPT) to non-orthogonal multiple access (NOMA) networks in which users are spatially randomly located is investigated. A new cooperative SWIPT NOMA protocol is proposed, in which near NOMA users that are close to the source act as energy harvesting relays to help far NOMA users. Since the locations of users have a significant impact on the performance, three user selection schemes based on the user distances from the base station are proposed. To characterize the performance of the proposed selection schemes, closed-form expressions for the outage probability and system throughput are derived. These analytical results demonstrate that the use of SWIPT will not jeopardize the diversity gain compared to the conventional NOMA. The proposed results confirm that the opportunistic use of node locations for user selection can achieve low outage probability and deliver superior throughput in comparison to the random selection scheme.

3-Dimensional Accuracy of Simplant Safeguide Fully Guided Implant Surgery
Creators: name: Gragg, Anthony
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Purpose: The aim of this retrospective study was to determine the accuracy along the x,y, and z axis as well as rotational accuracy when comparing the planned implant position in Simplant with the final, impressed, implant position using Geomagic12 studio software to overlay the positions. Materials: and Methods: Digital data for the pre-surgical planned implant location and post-surgical implant location as determined by an implant level impression was uploaded into Geomagic and computer modeling was used to compare the difference in 3-dimensional position, mesial-distal tip, buccal-lingual tip, apical depth and rotation. Results: In 3-dimensional space, the difference between the planned and final implant locations was 0.34mm for the x and z dimension and 0.31mm for the y dimension, for an overall median difference of 0.33mm. The median final implant location apically, compared with the planned location, was 0.4mm apical to the planned position. Angular difference between planned and final implant location was 0.47 degrees tipped to the mesial and 0.22 degrees tipped to the lingual. The rotational timing of the implants compared to Simplant’s decided timing for abutment placement was 3.19 degrees rotated clockwise. Conclusions: This novel way of evaluating accuracy of fully guided surgery eliminates the need for post-healing CBCTs, decreasing the cumulative radiation dose of our patients. Further investigation with large study populations will be necessary to verify the results. However, this data helps support the efficacy of current guided surgeries and why they should continue to be used whenever the clinical situation is deemed appropriate.

description: Recently, we have demonstrated that there exists a possible relationship between q-deformed algebras in two different contexts of Statistical Mechanics, namely, the Tsallis' framework and the Kaniadakis' scenario, with a local form of fractional-derivative operators for fractal media, the so-called Hausdorff derivatives, mapped into a continuous medium with a fractal measure. Here, in this paper, we present an extension of the traditional calculus of variations for systems containing deformed-derivatives embedded into the Lagrangian and the Lagrangian densities for classical and field systems. The results extend the classical Euler-Lagrange equations and the Hamiltonian formalism. The resulting dynamical equations seem to be compatible with those found in the literature, specially with mass-dependent and with nonlinear equations for systems in classical and quantum mechanics. Examples are presented to illustrate applications of the formulation. Also, the conserved Nether current, are worked out.

A mathematical model for predicting HR max, VO2 max, and oxygen uptake kinetics during treadmill walking and running at varied intensities
Creators: name: Borror, Andrew
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Maximal oxygen uptake (VO2 max) is difficult to measure and most predictions are inaccurate due to a variety of assumptions. The purpose of this study was to validate a dynamical system model (DSM) for predicting HR max and VO2 max during walking and running. A secondary purpose was to predict VO2 responses using a neural network. Twenty-six healthy males completed a maximal cardiopulmonary exercise test (CPET) and a submaximal protocol. The models were applied to the submaximal data to estimate the participants’ HR/VO2 responses and predict their HR max and VO2 max. The model accurately tracked HR and VO2 responses (R2 = -.85-0.99). However, it did not accurately estimate max (R2 < 0). Further refinement of the model is needed. This study elucidated some of the challenges of using a DSM and demonstrated that a neural network may be useful for easily predicting VO2 responses.

The Hijab and France
Creators: name: Abdelrahman, Faisal
Publisher: name: University of North Carolina at Chapel Hill Graduate School
Year: 2015

description: This paper addresses the 2004 French ban on hijabs being worn in France's public schools. Though legally phrased as a prohibition on conspicuous religious symbols, the debate on and subsequent passage of the ban was centered on the hijab; the head covering fabric that is traditionally associated with Muslim women. Through analysis of the debate this paper intends to answer the question of why hijabs were banned, arguing that a narrative of protecting the French concept of secularism known as laїcité was constructed to achieve broad support from French society when the real issues were centered on France's fears of Islam, the inability of Muslim immigrants to assimilate in French society, and the challenges that the Muslim French community presents to the traditional concept of French identity.

We show the formation of vesicles using amphiphilic copolymers whose chemical nature is chosen to control both membrane formation and membrane-confined interactions. We report polymersomes with patterns that emerge by engineering interfacial tension within the polymersome surface. This allows the formation of domains whose topology is tailored by the chemical synthesis paving the avenue to complex supramolecular designs functionally similar to those found in viruses and trafficking vesicles.

description: Magnetic interactions between a star and a close-in planet are postulated to be a source of enhanced emissions and to play a role in the secular evolution of the orbital system. Close-in planets generally orbit in the sub-alfvénic region of the stellar wind, which leads to efficient transfers of energy and angular momentum between the star and the planet. We model the magnetic interactions occurring in close-in star-planet systems with three-dimensional, global, compressible magneto-hydrodynamic numerical simulations of a planet orbiting in a self-consistent stellar wind. We focus on the cases of magnetized planets and explore three representative magnetic configurations. The Poynting flux originating from the magnetic interactions is an energy source for enhanced emissions in star-planet systems. Our results suggest a simple geometrical explanation for ubiquitous on/off enhanced emissions associated with close-in planets, and confirm that the Poynting fluxes can reach powers of the order of $10^{19}$ W. Close-in planets are also showed to migrate due to magnetic torques for sufficiently strong stellar wind magnetic fields. The topology of the interaction significantly modifies the shape of the magnetic obstacle that leads to magnetic torques. As a consequence, the torques can vary by at least an order of magnitude as the magnetic topology of the interaction varies.

description: We introduce a new class of unfitted finite element methods with high order accurate numerical integration over curved surfaces and volumes which are only implicitly defined by level set functions. An unfitted finite element method which is suitable for the case of piecewise planar interfaces is combined with a parametric mapping of the underlying mesh resulting in an isoparametric unfitted finite element method. The parametric mapping is constructed in a way such that the quality of the piecewise planar interface reconstruction is significantly improved allowing for high order accurate computations of (unfitted) domain and surface integrals. This approach is new. We present the method, discuss implementational aspects and present numerical examples which demonstrate the quality and potential of this method.

description: Academic success is commonly evaluated by the number of published articles. Yet, focusing on this single metric selects against female academics with biased gender roles both within households and within academic institution. Novel social conditions induced by the COVID19 pandemic likely exacerbated this gender-bias if female academics took on heavier loads of caregiving, domestic, service and teaching tasks. We investigate the overall pandemic effect on the gender gap in research productivity through a systematic review and meta-analysis of 130 effect sizes from 55 published articles across scientific disciplines.

 We also investigate how research field, breadth of gender gap before the pandemic, and authorship position influence this effect. We found that the gender gap in research productivity within academia has overall increased by 5% according to the numbers of publications and submissions during the COVID-19 pandemic, especially in social sciences and medicine, fields that were previously nearest to being gender equal, with less or no change in natural science fields. We did not detect an influence of authorship position.

 Based on our results, we call attention to the fact that traditional metrics of research productivity such as numbers of publications and submissions have disproportionately worsened for women researchers. Potentially, this could feedback into grant-allocation/tenure/promotion/hiring decisions, worsening academia’s “leaky pipeline”. The script and dataset in our systematic review and meta-analysis enables monitoring of longer-term effects by incorporating new research on the topic as and when it becomes available.
Performance Enhancement of Parameter Estimators via Dynamic Regressor Extension and Mixing

description: A new way to design parameter estimators with enhanced performance is proposed in the paper. The procedure consists of two stages, first, the generation of new regression forms via the application of a dynamic operator to the original regression. Second, a suitable mix of these new regressors to obtain the final desired regression form. For classical linear regression forms the procedure yields a new parameter estimator whose convergence is established without the usual requirement of regressor persistency of excitation. The technique is also applied to nonlinear regressions with "partially" monotonic parameter dependence---giving rise again to estimators with enhanced performance. Simulation results illustrate the advantages of the proposed procedure in both scenarios.

EXPLORING THE RELATIONSHIP BETWEEN PROFESSIONAL DEVELOPMENT LEADERS’ COMPETENCIES OF EFFECTIVE PROFESSIONAL LEARNING AND TEACHERS’ PERCEPTIONS OF PROFESSIONAL DEVELOPMENT
Creators: name: Mcknight, Gregory
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: The purpose of this study was twofold.  It first sought to establish a comprehensive framework that clearly outlined the competencies a district level professional development leader should have to design, deliver, and evaluate professional development for educators.  Next, the domain competencies were aligned to specific professional development survey items found in the North Carolina Teacher Working Conditions Survey.  The purpose of aligning the survey questions to the framework’s domain competencies was to investigate the relationship of professional development leaders’ competencies to teachers’ perceptions of professional development using a causal-comparative design.  The following research questions guided the study:
      1.  Which theories and practices frame the essential knowledge and competencies for professional development leaders to effectively design, deliver, and evaluate professional development?
      2.  How, if at all, do the competency levels of professional development leaders impact teachers’ perceptions of professional development in each domain?
      This causal-comparative study used the results from the 2014 North Carolina Teacher Working Conditions Survey (NCTWCS) and a self-assessment survey of professional development leaders’ competencies.  Those data were used to determine if the competency levels of professional development leaders impact teachers’ perceptions of professional development in their district.  A regression analysis was conducted using professional development leader competency as a predictor of teachers’ perceptions in each of the three domains.  The researcher then conducted a multiple regression model to explore if the differences in how leaders perceived their competency and teachers’ perceptions of professional development in each domain were predicted by district wealth.  The regression models revealed that a district’s wealth was not a predictor of the differences found within each domain.  The results were not statistically significant with both regression models, indicating that teachers’ perceptions of professional development were not impacted by the district’s wealth nor the competency level of the professional development leader.

description: Research consistently suggests that people high in social anxiety report lower self-compassion, and that self-compassion may be effective in reducing social stress. It has been theorized that self-compassion may useful for people with high social anxiety because it promotes adaptive regulation of shame around social situations, though few studies have directly explored self-compassion as a shame regulation strategy in this population. This two-study project aims to examine the relations between self-compassion in difficult social situations, shame and shame regulation strategies, and social anxiety. Secondly, this study aims to examine the spontaneous use of self-compassion following difficult social situations in daily life among participants with low and high levels of social anxiety. Participants for both studies will be recruited as part of project MESA and recruited using the website MTurk. Study one uses a cross-sectional survey design. Study two uses a 14-day daily diary design in which participants report nightly on one social interaction experienced during their day.
Collaboration Between Professional Cultures: An Investigation of Families’ Experiences of Inter-agency, Collaborative Mental Health Care

description: Children’s mental healthcare in Canada is undergoing a transition: instead of community- and hospital-based services working in parallel, there is a shift to increasing collaboration. When community- and hospital-based children’s mental health service providers work together, differences in their philosophical approaches to treatment can be revealed. However, client experiences of these philosophical differences have not been explored. In this hermeneutic phenomenological study, I interviewed young people and their families who had lived experience of collaboration in a mid-sized Canadian city. I considered the results of these interviews with families who were new to treatment that was shared between hospital- and community-based services in light of literature on current initiatives in collaborative mental health care. I situated my results in the context of my on-going work as a service provider in this Canadian city alongside the reflections of service providers from the two organizations that were the focus of my research: the Children's Hospital and the Community Agency. I found that young people and their parents experience their care as being in a constant state of crisis when connections between these services are not explicit. In contrast, when connections are clear, families feel more able to manage their children’s care. As well, service providers find that when explicit connections are forged between community-and hospital-based services, collaboration becomes more straightforward and is experienced as less hierarchical. The results of my research provide concrete tools, contextualized in the real worlds of current practitioners and clients, to help the future psychotherapists of Ontario work collaboratively towards supporting young people and their families who seek treatment for mental health diagnoses.

description: We develop the version of the $J$-invariant for hermitian forms over quadratic extensions in a similar way Alexander Vishik did it for quadratic forms. This discrete invariant contains informations about rationality of algebraic cycles on the maximal unitary grassmannian associated with a hermitan form over a quadratic extension. The computation of the canonical $2$-dimension of this grassmannian in terms of the $J$-invariant is provided, as well as a complete motivic decomposition.
