description: Prior investigations have demonstrated that people tend to link pseudowords such as bouba to rounded shapes and kiki to spiky shapes, but the cognitive processes underlying this matching bias have remained controversial. Here, we present three experiments underscoring the fundamental role of emotional mediation in this sound-shape mapping. Focusing on key previous research, we show that kiki-like pseudowords and spiky shapes, compared to bouba-like pseudowords and rounded shapes, always elicit higher levels of affective arousal, which we assessed through both subjective ratings (Experiment 1) and acoustic models implemented based on pseudoword material (Experiment 2). Crucially, the mediating effect of arousal generalizes to novel pseudowords representative of the language as a whole (Experiment 3). These findings highlight the role that human emotion may play in language development and evolution by grounding associations between abstract concepts (e.g., shapes) and linguistic signs (e.g., words) in the affective system.

description: Let $\operatorname{r_{max}}(n,d)$ be the maximum Waring rank for the set of all homogeneous polynomials of degree $d>0$ in $n$ indeterminates with coefficients in an algebraically closed field of characteristic zero. To our knowledge, when $n,d\ge 3$, the value of $\operatorname{r_{max}}(n,d)$ is known only for $(n,d)=(3,3),(3,4),(3,5),(4,3)$. We prove that $\operatorname{r_{max}}(3,d)=d^2/4+O(d)$ as a consequence of the upper bound $\operatorname{r_{max}}(3,d)\le\left\lfloor\left(d^2+6d+1\right)/4\right\rfloor$.

L’attitudine “astratta” del paesaggio
Creators: name: Morabito, Valerio
Publisher: name: Ri-Vista
Year: 2015

description: Calvino in his book, “Six memos for the next millennium”, speaks about a world made up of representations of images and forms. Against this biased or common vision, he says that he can only use “a weapon he knows well”: an idea of literature. Thus, he believes in the existence of a two-dimensional space, capable of creating a relationship between opposites, a vast scenario that moves in two directions, which proves that two worlds exist: the material and the anti-material. We can extrapolates this logic, in order to consider an”abstract attitude of landscape”: a two- dimensional space that allows us to pass from one reality to the other, from the material to the anti- material realm, a middle ground between the landscape and the anti-landscape.

Student-Generated Questions in Inquiry Science: Connecting to Collaborative Argumentation
Creators: name: Minshew, Lana M
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: The National Research Council (NRC) released the Next Generation Science Standards (NGSS Lead States, 2013) that established a framework for three-dimensional learning, which includes science and engineering practices, crosscutting concepts, and disciplinary core ideas. The first dimension of learning emphasizes scientific and engineering practices asserting that students should not only be familiar with scientific practices but also be able to successfully conduct an investigation utilizing the practices (NGSS Lead States, 2013). The science practices were included in the NGSS because knowing science content is not enough; students need to be able to use their understanding to investigate the natural world (NGSS Lead States, 2013). The expectation is that students not just know science content but can participate in science exploration and the many discourses of science. The scientific practices intentionally overlap one another and are interconnected; they do not operate in isolation (NGSS Lead States, 2013). However, little is known about how the scientific practices overlap, specifically how one scientific practice influences another. Studies often focus on students’ development or implementation of a single scientific practice such as developing and using models or engaging in argumentation. This dissertation study aimed to examine the relationship between questions posed and dialogical arguments constructed by students during collaborative work in small groups during a designed curricular unit titled Compost. The focus was on questions and dialogical arguments that arose naturally as students’ participated in a collaborative project-based inquiry science curriculum. The data from this study showed that students’ questions helped them to navigate the science content presented in the Compost curricular unit. Students’ questions directed student thinking by enabling them to share their prior knowledge, identify points of uncertainty, challenge each others’ ideas, as well as generate and occasionally sustain increasingly complex instances of argumentation.

description: We study a system of Dirac electrons with finite density of charge carriers coupled to an external electromagnetic field in two spatial dimensions, with a domain wall (DW) mass term. The interface between a thin-film ferromagnet and a three-dimensional topological insulator provides a condensed-matter realization of this model, when an out-of-plane domain wall magnetization is coupled to the TI surface states. We show how, for films with very weak intrinsic in-plane anisotropies, the torque generated by the edge electronic current flowing along the DW competes with an effective in-plane anisotropy energy, induced by quantum fluctuations of the chiral electrons bound to the wall, in a mission to drive the internal angle of the DW from a Bloch configuration towards a Néel configuration. Both the edge current and the induced anisotropy contribute to stabilize the internal angle, so that for weak intrinsic in-plane anisotropies DW motion is still possible without suffering from an extremely early Walker breakdown.

This is an interesting lesson, wich in- vites to reflect on different readings: behind a simple travel book, that fascinates, amuses and in- trigues, there are many important ideas that emerge in the watermark. They concern some of the most pressing issues about landscape.

description: R-process nucleosynthesis models rely, by necessity, on nuclear structure models for input. Particularly important are beta-decay half-lives of neutron rich nuclei. At present only a single systematic calculation exists that provides values for all relevant nuclei making it difficult to test the sensitivity of nucleosynthesis models to this input. Additionally, even though there are indications that their contribution may be significant, the impact of first-forbidden transitions on decay rates has not been systematically studied within a consistent model. We use a fully self-consistent covariant density functional theory (CDFT) framework to provide a table of $β$-decay half-lives and $β$-delayed neutron emission probabilities, including first-forbidden transitions. We observe a significant contribution of the first-forbidden transitions to the total decay rate in nuclei far from the valley of stability. The experimental half-lives are in general well reproduced, both for even-even, odd-A and odd-odd nuclei, in particular for short-lived nuclei.

Spontaneous symmetry breaking and Nambu-Goldstone modes in dissipative systems

description: We discuss spontaneous breaking of internal symmetry and its Nambu-Goldstone (NG) modes in dissipative systems. We find that there exist two types of NG modes in dissipative systems corresponding to type-A and type-B NG modes in Hamiltonian systems. To demonstrate the symmetry breaking, we consider a $O(N)$ scalar model obeying a Fokker-Planck equation. We show that the type-A NG modes in the dissipative system are diffusive modes, while they are propagating modes in Hamiltonian systems. We point out that this difference is caused by the existence of two types of Noether charges, $Q_R^α$ and $Q_A^α$: $Q_R^α$ are symmetry generators of Hamiltonian systems, which are not conserved in dissipative systems. $Q_A^α$ are symmetry generators of dissipative systems described by the Fokker-Planck equation, which are conserved. We find that the NG modes are propagating modes if $Q_R^α$ are conserved, while those are diffusive modes if they are not conserved. We also consider a $SU(2)\times U(1)$ scalar model with a chemical potential to discuss the type-B NG modes. We show that the type-B NG modes have a different dispersion relation from those in the Hamiltonian systems.

A Parallel Plate Reactor Built with Wall Materials for Indoor Surface Chemistry Study
Creators: name: Cui, Liyong
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Indoor air exposures in damp homes are associated with adverse health effects. These associations might be explained, in part, by indoor surface chemistry. In this study, a parallel plate laminar flow reactor was designed to understand the hygroscopicity of indoor surfaces and indoor gas reactive uptake. We introduced three parallel plate flow reactor scenarios: continuously mixed flow reactor (CMFR), plug flow reactor, and laminar flow reactor to evaluate the performance and limitations of this design. With the plug flow design, we expect to be able to measure uptake coefficients (𝛾) from 10^-5 to 10^-6 for gases with a transport-limited deposition velocities (vt) in the range 0.02 ~ 0.2 cm/s. Furthermore, because we can measure vt for ozone, we can predict vt for other small polar organic compounds under similar gas concentrations and flow conditions. With this information, uptake coefficients for small polar organic compounds can then be calculated.

description: The aim of this work is to investigate and characterise particle behaviour in a 3D magnetohydrodynamic (MHD) model of a reconnecting magnetic separator. We use a relativistic guiding-centre test-particle code to investigate electron and proton acceleration in snapshots from 3D MHD separator reconnection experiments, and compare the results with findings from an analytical separator reconnection model studied in a previous investigation. The behaviour and acceleration of large distributions of particles are examined in detail for both analytical and numerical separator reconnection models. Accelerated particle orbit trajectories are shown to follow the separator before leaving the system along the separatrix surface of one of the nulls (determined by particle species) in the system of both models. A sufficiently localised electric field about the separator causes the orbits to appear to follow the spine bounding the separatrix surface field lines instead. We analyse and discuss the locations and spread of accelerated particle orbit final positions, which are seen to change over time in the numerical separator reconnection model. We deduce a simple relationship between the final energy range of particle orbits and the model dimensions, and discuss its implications for observed magnetic separators in the solar corona.

Improving Methods for Propensity Score Analysis with Mis-Measured Variables by Incorporating Background Variables with Moderated Nonlinear Factor Analysis
Creators: name: Greifer, Noah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: There has been some research in the use of propensity scores in the context of measurement error in the confounding variables; one recommended method is to generate estimates of the mis-measured covariate using a latent variable model, and to use those estimates (i.e., factor scores) in place of the covariate. I describe a simulation study designed to examine the performance of this method in the context of differential measurement error and propose a method based on moderated nonlinear factor analysis (MNLFA) to try to address known problems with standard methods. Although MNLFA improves effect estimation somewhat in the presence of differential measurement error relative to standard factor analysis methods, the greatest gains come from the nonstandard practice of including the treatment variable as an indicator in the scoring models. More research is required on the effects of model misspecification on the performance of these methods for causal inference applications.
On the Convergence of the Iterative Shrinkage/Thresholding Algorithm With a Weakly Convex Penalty
Creators: name: Bayram, Ilker
Publisher: name: arXiv
Year: 2015
Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics

description: We consider the iterative shrinkage/thresholding algorithm (ISTA) applied to a cost function composed of a data fidelity term and a penalty term. The penalty is non-convex but the concavity of the penalty is accounted for by the data fidelity term so that the overall cost function is convex. We provide a generalization of the convergence result for ISTA viewed as a forward-backward splitting algorithm. We also demonstrate experimentally that for the current setup, using large stepsizes in ISTA can accelerate convergence more than existing schemes proposed for the convex case, like TwIST or FISTA.
Il paesaggio nell’arena globale. Il XXIII Congresso Mondiale UIA e altri dibattiti

description: On the basis of the topics discussed in two recent International meetings, the XXIII UIA Congress and the V European Landscape Biennial, and in recently appeared manifestos, some reflections about the contemporary “sense of landscape” will be addressed. While “landscape” is used as a green metaphor in architectural fields, the landscape disciplines seems to adopt two different strategies: a return to beauty and emotion as a specificity (therefore tracing a distinction from ecology) and hybridization with urbanism. Thus, the debate shows an attempt to compare the topics of the discipline to the social aspirations, like beauty, sustainability, urbanity.

Dorsal hippocampal astrocyte signaling regulates heroin-conditioned immunomodulation but not heroin-conditioned place preference
Creators: name: Paniccia, Jacqueline
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Repeated context-heroin pairings result in Pavlovian associations that manifest as heroin-conditioned appetitive responses or peripheral immunomodulation upon re-exposure to heroin-conditioned stimuli. The dorsal hippocampus (DH) is a critical neural substrate governing these context-heroin associations. Within the DH, there appears to be divergent mechanisms mediating heroin-conditioned Pavlovian responses. Evidence suggests that DH interleukin-1 signaling regulates heroin-conditioned immunomodulation but not heroin-conditioned place preference (CPP). The present study sought to further investigate the role of DH neuroimmune signaling in heroin-conditioned Pavlovian responses. Astroglial activity has been implicated in both drug addiction and mechanisms of learning and memory. As such, we employed chemogenetic tools to examine the involvement of DH astrocytes in the expression of both heroin-conditioned immunomodulatory and appetitive responses. Interestingly, chemogenetic stimulation of DH astroglial Gi-signaling disrupted heroin-conditioned immunomodulation but did not alter heroin-CPP. These data provide further evidence that differential DH mechanisms regulate heroin-conditioned Pavlovian responses.

description: Varying technologies and experimental approaches used in microbiome studies often lead to irreproducible results due to unwanted technical variations. Such variations, often unaccounted for and of unknown source, may interfere with true biological signals, resulting in misleading biological conclusions. In this work, we aim to characterize the major sources of technical variations in microbiome data and demonstrate how in-silico approaches can minimize their impact. We analyzed 184 pig faecal metagenomes encompassing 21 specific combinations of deliberately introduced factors of technical and biological variations. Using the novel Removing Unwanted Variations-III-Negative Binomial (RUV-III-NB), we identified several known experimental factors, specifically storage conditions and freeze–thaw cycles, as likely major sources of unwanted variation in metagenomes. We also observed that these unwanted technical variations do not affect taxa uniformly, with freezing samples affecting taxa of class Bacteroidia the most, for example. Additionally, we benchmarked the performances of different correction methods, including ComBat, ComBat-seq, RUVg, RUVs, and RUV-III-NB. While RUV-III-NB performed consistently robust across our sensitivity and specificity metrics, most other methods did not remove unwanted variations optimally. Our analyses suggest that a careful consideration of possible technical confounders is critical during experimental design of microbiome studies, and that the inclusion of technical replicates is necessary to efficiently remove unwanted variations computationally.

Petrykivka Painting: the Questions of Politics, Authenticity and Identity in Modern Ukraine
Creators: name: Voloshyna, Iryna
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: This thesis documents Petrykivka painting, a Ukrainian folk art technique, through the lenses of history and modernity, drawing on interviews with core contemporary artists and promoters. Petrykivka artists hold varying opinions regarding the development of the art form and the ways in which it represents both Ukrainian-ness to Ukrainians and Ukrainian culture on the international art scene. By exploring dialogues circulating in the community, I argue that Petrykivka artists feel that what they are doing today is still traditional and authentic, even though the art might look different from a century or more ago and its meaning might have changed, too. Recognizing critical debates around the concept of authenticity, I inquire into the grounds of the artists’ claims. I highlight complex relationships between their flexibility regarding aspects of technique and appearance and their insistence that only an artist with deep connections to the village can create “true” Petrykivka.

We then propose a new prescription for the combination of a suitable subset of the available PDF sets, which is presented in terms of a single combined PDF set. We finally discuss tools which allow for the delivery of this combined set in terms of optimized sets of Hessian eigenvectors or Monte Carlo replicas, and their usage, and provide some examples of their application to LHC phenomenology.

description: The purpose of this research was to explore collegiate educational experiences and current life satisfaction of former Division I football players 20 years post-college at one Power 5 Southeastern institution, to serve as a pilot study for future research on the subject. Football players were compared to a general student population, and the two samples were compared between Caucasian and minority students across numerous scales and metrics to measure quality of life and other demographic and qualitative questions. Significance was found in one survey question comparing football players and general students, but comparisons within football between Caucasian and minority students yielded many areas of significance, including satisfaction with life.  In examining just one school in one year, this study serves as a pilot study for future research attempting to connect educational experiences of athletes to their current standard of living and ways of life.

Forty years later, “Guerrilla Gardening” became an international network of independent activists fighting against globalized commerce and the strict rules of urban planning to improve the quality of open space. They regenerated forbidden public and private open spaces at different scales: from small sizes such as public flowerbeds to large pieces of land around the city. The legacy of “Guerrilla Gardening” creates an opportunity for urban planners and architects to rethink the strategy of open space in the urban environment and to realize the importance of informal work in the transformation and management process of the city.

Neutrino Mixing: $A_4$ Variations
Creators: name: Ma, Ernest
Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In the context of the non-Abelian discrete symmetry $A_4$, the neutrino mass matrix has been studied extensively. A brief update is presented to focus on the conceptual shift from tribimaximal mixing ($θ_{13} = 0$, $θ_{23} = π/4$, $\tan^2 θ_{12} = 1/2$) to $\underline{\rm cobimaximal}$ mixing ($θ_{13} \neq 0$, $θ_{23} = π/4$, $δ_{CP} = \pm π/2$) which agrees well with present data. Three specific realistic examples are proposed, two with three and the third with just two parameters.

description: Efficient light-matter interaction lies at the heart of many emerging technologies that seek on-chip integration of solid-state photonic systems. Plasmonic waveguides, which guide the radiation in the form of strongly confined surface plasmon-polariton modes, represent a promising solution to manipulate single photons in coplanar architectures with unprecedented small footprints. Here we demonstrate coupling of the emission from a single quantum emitter to the channel plasmon polaritons supported by a V-groove plasmonic waveguide. Extensive theoretical simulations enable us to determine the position and orientation of the quantum emitter for optimum coupling. Concomitantly with these predictions, we demonstrate experimentally that 42% of a single nitrogen vacancy centre emission efficiently couples into the supported modes of the V-groove. This work paves the way towards practical realization of efficient and long distance transfer of energy for integrated solid-state quantum systems.

description: There are many inflationary models that allow the formation of the large-scale structure of the observable universe. The non-gaussianity parameter $f_{NL}$ is a useful tool to discriminate among these cosmological models when comparing the theoretical predictions with the satellite survey results like those from WMAP and Planck. The goal of this proceeding contribution is to review the moment transport equations methodology and the subsequent calculation of the $f_{NL}$ parameter.

Russian Empire-Building and the Kazakh Kinship System: The Chala-Qazaqs of the Kazakh steppe
Creators: name: Kabdylkhak, Nurlan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: This thesis examines the phenomenon of Chala-Qazaqs: groups of mixed ethnic origin who lived in the Kazakh steppe. Chala-Qazaqs, or “half-Kazakhs,” emerged as a result of the rigid kinship system and patrilineal succession adopted by the steppe nomads. Since Kazakhs inherited their tribal identities from their fathers, they placed the progeny of Kazakh mothers and non-Kazakh fathers in the hybrid category of Chala-Qazaqs. Chala-Qazaq could serve as a transitional status on the way to becoming “fully” Kazakh. This “Kazakhification” was evinced by their incorporation into Kazakh tribal genealogies. This paper reveals that this process stopped in the nineteenth century due to the transformation of the Kazakh kinship system and the emergence of Chala-Qazaqs as a distinct social category – two inter-related shifts connected to Russian imperial expansion. Chala-Qazaqs present a fascinating case that exposes ethnic processes in pre-colonial and colonial settings and demonstrate the agency of Muslims under the Russian rule.
Viaggiare per osservare. Noterelle dall’esperienza del viaggiatore Roberto Burle Marx
Creators: name: Rizzo, Giulio
Publisher: name: Ri-Vista
Year: 2015

description: One hundred years ago, in August 4 1909, Roberto Burle Marx was born in São Paulo. Ri-Vista and its director intend to remember him by this brief article with the gratitude due to the world-wide Master in landscape design. The journeys, and more, the expeditions, which he did in the Brazilian forests taught generations of landscape architects the importance of research on site. It certainly is the main road to the deep comprehension of the natural and aesthetic features of the species to use those in design compositions by less possible violence.

Indemnización de daños causados por el cártel de fabricantes de camiones: comentario a la sentencia del tribunal supremo alemán de 23 de septiembre de 2020 (KZR 35/19)

description: En su sentencia de 23 de septiembre de 2020, el Tribunal Supremo alemán (BGH) clarifica algunas de las dudas que se han suscitado en los tribunales alemanes sobre las reclamaciones de daños derivados de ílicitos concurrenciales. Aunque el fallo se centra en cuestiones específicas relativas al cártel de fabricantes de camiones, el pronunciamiento sigue la línea de decisiones previas del BGH sobre los daños causados por el cártel de los raíles, el cártel del cemento gris y el cártel del papel auto-copiativo. La sentencia consolida el acervo jurisprudencial del BGH que adapta las reglas y principios del tradicional Derecho de daños a estos litigios. La sentencia del BGH despeja muchas de las dificultades que afrontan las acciones de daños consecutivas (follow-on) tras una decisión sancionadora de la autoridad de competencia (en este caso de la Comisión Europea), en materia de: legitimación activa de las víctimas, prueba y presunción del daño, responsabilidad conjunta y solidaria de las empresas partícipes en el cártel y prescripción del derecho a reclamar. Algunos de los pronunciamientos del BGH desenredan aspectos idiosincráticos del proceso y las normas vigentes en Alemania, pero por encima de ello, la sentencia adapta la jurisprudencia previa del Tribunal de Karlsrhue a las singularidades del cártel de los fabricantes de camiones, fijando criterios que emanan de las últimas decisiones del Tribunal de Justicia de la UE sobre reclamaciones de daños antitrust (v. gr., en materia de "daños paraguas" y sobre la defensa de la repercusión del daño).

description: We study tilting complexes over preprojective algebras of Dynkin type. We classify all tilting complexes by giving a bijection between tilting complexes and the braid group of the corresponding folded graph. In particular, we determine the derived equivalence class of the algebra. For the results, we develop the theory of silting-discrete triangulated categories and give a criterion of silting-discreteness.

description: The landscape is the primary encyclopaedia of our knowledge. The different grade of touristic appeal for different destinations and typical products depends on the sensations of everyone (inhabitant or tourist). Every subject links his experience with the pleasure to belong to that place. In the wine and gastronomic tourism the landscape is more interesting because the tourist tastes it with all five senses, crossing and discovering the different places.

Cupid Returns: An Analysis of Cupid’s Metamorphosis in Apuleius’ ‘Cupid and Psyche’
Creators: name: Sherry, Matthew W
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: In this paper I focus on Apuleius’ presentation of Cupid, arguing that Cupid rejects his traditional role and transforms into a more benevolent deity. I first analyze the way that his divine peers describe him in traditional terms: a mischievous figure who manipulates others and scorns marital fidelity. A close reading of the text shows that his actions in this story actually convey the opposite. These descriptions in fact better suit Apuleius’ Venus. I then examine Cupid’s “return to the wine jar” (6.22.1), a phrase that indicates a return to vice. Cupid’s vice, as we learn from the traditional descriptions, is his manipulation of others. At the end of the tale, Cupid returns to this vice but in the service of a new goal: marriage to Psyche. I argue that Cupid’s return marks the culmination of his transformation and that Apuleius presents Cupid as the personification of Unconditional Love.
