description: In a previous work we analysed the white-light coronal brightness as a function of elongation and time from Wide-Field Imager (WISPR) observations on board the Parker Solar Probe (PSP) mission when PSP reached a minimum heliocentric distance of ~ 28 Rs. We found 4-5 transient outflows per day over a narrow wedge in the PSP orbital plane, which is close to the solar equatorial plane. However, the elongation versus time map (J-map) analysis supplied only lower limits on the number of released density structures due to the small spatial-scales of the transient outflows and line-of-sight integration effects. In this work we place constraints on the properties of slow solar wind transient mass release from the entire solar equatorial plane. We simulated the release and propagation of transient density structures in the solar equatorial plane for four scenarios: (1) periodic release in time and longitude with random speeds; (2) corotating release in longitude, periodic release in time with random speeds; (3) random release in longitude, periodic release in time and speed; and (4) random release in longitude, time, and speed. The simulations were used in the construction of synthetic J-maps, which are similar to the observed J-map. The four considered scenarios have similar ranges (35-45 for the minimum values and 96-127 for the maximum values) of released density structures per day from the solar equatorial plane and consequently from the streamer belt, given its proximity to the solar equatorial plane during the WISPR observation. Our results also predict that density structures with sizes in the range 2-8 Rs, covering 1-20 % of the perihelion could have been detectable by PSP in situ observations during that interval.

description: We demonstrate the first functional signal processing device based on stimulated Brillouin scattering in a silicon nanowire. We use only 1 dB of on-chip SBS gain to create an RF photonic notch filter with 48 dB of suppression, 98 MHz linewidth, and 6 GHz frequency tuning. This device has potential applications in on-chip microwave signal processing and establishes the foundation for the first CMOS-compatible high performance RF photonic filter.
ind the Gap: An Analysis of the Landscape of the Policies of the United States and Germany, and NGOs on Improving Digital Integration for Refugee Populations
Creators: name: Connell, Megan Rose

Year: 2019

description: The 2015 refugee crisis has drastically altered the socio-political landscape within the European Union and has left European states with a unique set of immigrant integration challenges. Economic integration an important lens through which overall immigrant integration can be understood. Literacy, and increasingly, digital literacy, is often key to the accessibility of economic opportunity.       This thesis will seek to explore how the governments of the United States and Germany address the digital gap for refugees within their borders, through the lens of the importance of the digital divide to integration into the digital economy. Through a review of the federal refugee integration policies, the budgets of particular non-governmental organizations, and the programs of these non-governmental organizations, this thesis finds that in both the United States and German cases, lack of a central, federal digital inclusion policy creates a varied landscape of assistance.

description: In this paper we apply fluid-lattice gas global isomorphism approach to liquid-vapor equilibrium of Yukawa attractive fluid in the two dimensions. The construction of tangent to the binodal of the fluid in the low-temperature region is performed based on the Zeno-element. The dependence of Zeno-element and Boyle parameters on interaction parameters is also studied. It is shown that the asymptotic behavior of the Zeno-element parameters can serve as a marker for liquid phase instability in this case. We also provide the relation between critical temperatures of bulk (3D) and monolayer (2D) fluid.

description: We present a transfer learning analysis on a sporting environment of the expanded 3D (X3D) neural networks. Inspired by action quality assessment methods in the literature, our method uses an action recognition network to estimate athletes' cumulative race time (CRT) during an ultra-distance competition. We evaluate the performance considering the X3D, a family of action recognition networks that expand a small 2D image classification architecture along multiple network axes, including space, time, width, and depth. We demonstrate that the resulting neural network can provide remarkable performance for short input footage, with a mean absolute error of 12 minutes and a half when estimating the CRT for runners who have been active from 8 to 20 hours. Our most significant discovery is that X3D achieves state-of-the-art performance while requiring almost seven times less memory to achieve better precision than previous work.

EXAMINING RACE DIFFERENCES IN FIRST-YEAR EMPLOYMENT AMONG LOW-INCOME, RURAL MOTHERS:  IMPLICATIONS FOR CHILDREN’S LANGUAGE AND BEHAVIORAL DEVELOPMENT
Creators: name: Bezdek, Kylie Garber
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: This study examined the moderating role of race in the effect of first-year maternal employment and characteristics of employment on children’s expressive language skills and externalizing behavior problems at 36-months among 1,234 low-income, rural families.  Using propensity score weighting to account for selection bias, employment was not generally negative, and did not differ by race. Going back to work between six and fifteen months and higher negative work-family spillover predicted deficits in children’s language skills and behavior problems, respectively.  Race moderated the relation between timing and language skills, such that only children of White mothers were at a disadvantage when their mother started work later in infancy.  These findings suggest that there are specific characteristics of maternal employment that negatively affect different aspects of child development, and race differences in the effect of employment may be more nuanced than previously documented.
Multiple Scattering of Seismic Waves from Ensembles of Upwardly Lossy Thin Flux Tubes

description: Our previous semi-analytic treatment of f- and p-mode multiple scattering from ensembles of thin flux tubes (Hanson and Cally, Astrophys. J. 781, 125; 791, 129, 2014) is extended by allowing both sausage and kink waves to freely escape at the top of the model using a radiative boundary condition there. As expected, this additional avenue of escape, supplementing downward loss into the deep solar interior, results in substantially greater absorption of incident f- and p-modes. However, less intuitively, it also yields mildly to substantially smaller phase shifts in waves emerging from the ensemble. This may have implications for the interpretation of seismic data for solar plage regions, and in particular their small measured phase shifts.

description: We sketch the main features of the Noether Symmetry Approach, a method to reduce and solve dynamics of physical systems by selecting Noether symmetries, which correspond to conserved quantities. Specifically, we take into account the vanishing Lie derivative condition for general canonical Lagrangians to select symmetries. Furthermore, we extend the prescription to the first prolongation of the Noether vector. It is possible to show that the latter application provides a general constraint on the infinitesimal generator $ξ$, related to the spacetime translations. This approach can be used for several applications. In the second part of the work, we consider a gravity theory including the coupling between a scalar field $ϕ$ and the Gauss-Bonnet topological term $\mathcal{G}$. In particular, we study a gravitational action containing the function $F(\mathcal{G}, ϕ)$ and select viable models by the existence of symmetries. Finally, we evaluate the selected models in a spatially-flat cosmological background and use symmetries to find exact solutions.

DARIUS I IN EGYPT: ACHAEMENID AUTHORITY AND EGYPTIAN CONTINUITY

description: ABSTRACT      Rachael Tobin-Dodd: Darius I in Egypt: Achaemenid Authority and Egyptian Continuity      (Under the direction of Jennifer Gates-Foster)      The ideological systems of the Persian Great King and the Egyptian Pharaoh were      inherently in conflict. The Egyptian Pharaoh was responsible for defeating foreign enemies,      including Achaemenid Persians, while the Persian Great King was the ruler of a universal      empire. The Persian king, Darius I, had to embody both roles in order to maintain his rule over      Egypt. By examining three Egyptian artifacts that depict Darius and originate from different      socio-political spheres, I assess the different ways he was portrayed and consider the ways these      images navigated the inherent ideological conflict between the Great King and the Egyptian      Pharaoh. This analysis reveals a pattern in which Darius was presented to an Egyptian audience      as an Egyptian Pharaoh that has taken on visual attributes of the Achaemenid Great King, but to      a Persian audience, Darius was presented as an entirely Achaemenid conqueror.

description: We generalize the concept of Berry connection of the single-electron band structure to the two-particle Cooper pair states between two Fermi surfaces with opposite Chern numbers. Because of underlying Fermi surface topology, the pairing Berry phase acquires non-trivial monopole structure. Consequently, pairing gap functions have the topologically-protected nodal structure as vortices in the momentum space with the total vorticity solely determined by the monopole charge $q_p$. The pairing nodes behave as the Weyl-Majorana points of the Bogoliubov-de Gennes pairing Hamiltonian. Their relation with the connection patterns of the surface modes from the Weyl band structure and the Majorana surface modes inside the pairing gap is also discussed. Under the approximation of spherical Fermi surfaces, the pairing symmetry are represented by monopole harmonic functions. The lowest possible pairing channel carries angular momentum number $j=|q_p|$, and the corresponding gap functions are holomorphic or anti-holomorphic functions on Fermi surfaces.

description: The phase diagram of a half-filled hard core boson two-leg ladder in a flux is investigated by means of numerical simulations based on the Density Matrix Renormalization Group (DMRG) algorithm and bosonization. We calculate experimentally accessible observables such as the momentum distribution, as well as rung current, density wave and bond-order wave correlation functions, allowing us to identify the Mott Meissner and Mott Vortex states. We follow the transition from commensurate Meissner to incommensurate Vortex state at increasing interchain hopping till the critical value [Piraud et al. Phys. Rev. B v. 91, p. 140406 (2015)] above which the Meissner state is stable at any flux. For flux close to $π$, and below the critical hopping, we observe the formation of a second incommensuration in the Mott Vortex state that could be detectable in current experiments.

description: In this thesis, I draw on exploratory research conducted in the fall of 2018 to explore questions concerning the logics of mass casualty incident (MCI) preparedness operating in medical institutions and local governments within the Research Triangle region of North Carolina. Interviews with emergency management administrators, emergency medicine physicians, and first responders revealed that the unique forms of coordinated preparation and response that MCIs require, refashions personal and institutional relationships into capacity building resources that work across time and space. Drawing on social science literature on preparedness and infrastructure, this analysis will show that whether it be through time, space or both, the network of relationships developed through the work of MCI preparedness serves diverse roles and functions: as pathways and grounds for the movement of people, objects, and knowledge. These relationships and the resources they move collectively constitute an infrastructure of MCI preparedness.

description: A novel original method of determination of stresses and critical resolved shear stresses (CRSSs) using neutron diffraction was proposed. In this method, based on the crystallite group method, the lattice strains were measured in different directions and using different reflections hkl during uniaxial deformation of magnesium alloy AZ31. The advantage of this method is that the stresses for groups of grains having similar orientations can be determined directly from measurement without any models used for data interpretation. The obtained results are unambiguous and do not depend on the models assumptions as in previous works. Moreover, it was possible for the first time to determine the uncertainty of the measured CRSS values and local stresses at groups of grains. The used methodology allowed for the determination of stress partitioning between grains having different orientations and for an explanation of the anisotropic mechanical behaviour of the strongly textured alloy. Finally, the CRSS values allowed for the validation of the type of intergranular interaction assumed in the elastic-plastic self-consistent model and for a significant reduction of the number of unknown parameters when the model is adjusted to the experimental data.

Ecomusei e turismo

description: The drafting of the bill presented to the House of Representatives in October 2009 and the will to establish a commission within the Ministry of Tourism for the development of ecomuseums have fostered a period of debate on the relationship between ecomuseum systems and the touristic promotion of the territory. This is certainly not to invite mass tourism, but the tourism that is respectful to cultural heritage and that the eco- museums, with their participatory nature and their attention to the diffuse valorisation of the local landscape and identity, can adequately support. Tourism, seen as cultural exchange, is a lever for local development, able to promote the activation of resources in territorial management and to generate new economies with a strong cultural component, among which the eco-museum has an innovative potential. In this perspective, the economical aim is not only the value-added integration of eco-museums and tourism, but it also regards building cultural and socio-economic relationships, with internal and external entities to the local system, eliminating the implicit dangers of becoming self-referential and obsolete.

description: In the tourist context, the landscape meaning, as defined by the European Landscape Convention (ELC), is not yet well understood: actually, landscape is just conceived as a scenic view of the territory (panorama). This situation limits the role that landcape observation should play in policies aimed at promoting a sustainable and competitive tourism development. In order that landscape become a crucial element in visiting and knowing the territory, it is necessary to activate popularization methods able to capture and stimulate the tourist interests. The adoption of polularization methods could make tourism an extraorinary opportunity for applying the ELC principles, as they contitute important tools also for landscape sensitization.

description: Nitrogen hydrides such as NH$_3$ and N$_2$H$^+$ are widely used by Galactic observers to trace the cold dense regions of the interstellar medium. In external galaxies, because of limited sensitivity, HCN has become the most common tracer of dense gas over large parts of galaxies. We provide the first systematic measurements of N$_2$H$^+$(1-0) across different environments of an external spiral galaxy, NGC6946. We find a strong correlation ($r>0.98,p<0.01$) between the HCN(1-0) and N$_2$H$^+$(1-0) intensities across the inner $\sim8\mathrm{kpc}$ of the galaxy, at kiloparsec scales. This correlation is equally strong between the ratios N$_2$H$^+$(1-0)/CO(1-0) and HCN(1-0)/CO(1-0), tracers of dense gas fractions ($f_\mathrm{dense}$). We measure an average intensity ratio of N$_2$H$^+$(1-0)/HCN(1-0)$=0.15\pm0.02$ over our set of five IRAM-30m pointings. These trends are further supported by existing measurements for Galactic and extragalactic sources. This narrow distribution in the average ratio suggests that the observed systematic trends found in kiloparsec-scale extragalactic studies of $f_\mathrm{dense}$ and the efficiency of dense gas (SFE$_\mathrm{dense}$) would not change if we employed N$_2$H$^+$(1-0) as a more direct tracer of dense gas. At kiloparsec scales our results indicate that the HCN(1-0) emission can be used to predict the expected N$_2$H$^+$(1-0) over those regions. Our results suggest that, even if HCN(1-0) and N$_2$H$^+$(1-0) trace different density regimes within molecular clouds, subcloud differences average out at kiloparsec scales, yielding the two tracers proportional to each other.

description: We present GM2Calc, a public C++ program for the calculation of MSSM contributions to the anomalous magnetic moment of the muon, $(g-2)_μ$. The code computes $(g-2)_μ$ precisely, by taking into account the latest two-loop corrections and by performing the calculation in a physical on-shell renormalization scheme. In particular the program includes a $\tanβ$ resummation so that it is valid for arbitrarily high values of $\tanβ$, as well as fermion/sfermion-loop corrections which lead to non-decoupling effects from heavy squarks. GM2Calc can be run with a standard SLHA input file, internally converting the input into on-shell parameters. Alternatively, input parameters may be specified directly in this on-shell scheme. In both cases the input file allows one to switch on/off individual contributions to study their relative impact. This paper also provides typical usage examples not only in conjunction with spectrum generators and plotting programs but also as C++ subroutines linked to other programs.

Global $U(1)_Y$xBRST symmetry and the LSS theorem: Ward-Takahashi identities governing Green's functions, on-shell T-Matrix elements, and the effective potential, in the spontaneously broken extended Abelian Higgs model

description: The weak-scale U(1) Abelian Higgs Model (AHM) is the simplest spontaneous symmetry breaking (SSB) gauge theory. The extended AHM (E-AHM) adds certain heavy scalars $Φ$ and fermions $ψ$. In Lorenz gauge, these theories have a global U(1) conserved physical current, but no conserved charge. As shown by Kibble, the Goldstone theorem applies, there is a massless derivatively coupled Nambu-Goldstone boson (NGB). Proof of all-loop-orders renormalizability and unitarity is tricky because the BRST-invariant Lagrangian is not U(1) symmetric. Nevertheless, Slavnov-Taylor identities guarantee that on-shell T-matrix elements of physical states are independent of anomaly-free gauge transformations. We observe that they are therefore also independent of the usual anomaly-free U(1) global transformations. It follows that the associated global current, is exactly conserved for amplitudes of physical states. We identify corresponding Ward-Takahashi identities (WTI). In Lorenz gauge, two towers of "1-soft-pion" global WTI govern the scalar-sector, and represent a new global U(1)xBRST symmetry not of the Lagrangian but of the physics. The first gives relations among off-shell Green's functions, the second governs on-shell T-matrix elements, replacing the Adler self-consistency conditions. These WTI constrain the all-loop-orders scalar-sector low-energy effective Lagrangian. Consequently, certain heavy CP-conserving heavy matter representations decouple completely in the $M_{Heavy}^2/m_{Weak}^2 \to \infty$ limit. SSB (E-)AHM physics therefore has more symmetry than does its BRST-invariant Lagrantian. The NGB decouples from the observable particle spectrum in the usual way, when the observable vector absorbs it, as if it were a gauge transformation, hiding both towers of WTI from observable particle physics.

Paesaggi mentali e vivibilità nei luoghi alpini. Trasformazione dei luoghi in paesaggi. Percezione, sense-making e turismo
Creators: name: Morelli, Ugo
Publisher: name: Ri-Vista
Year: 2015

description: In the transformation process by which the sites become landscapes and also take the form of tourist landscapes, historical-evolutionary, affective, cognitive and socio-economic aspects are involved; their complexity requires a selection of perspective to be analyzed. This is a process both of introjection and projection, that, at the same time, produces knowledge, by means of symbolic competence. It is giving them a sense, then, that we know the places and the nature to which we belong. This essay examines the implications of the question through an approach that favours the orientations of applied cognitive sciences.

description: The link between Northern and Southern Italy was created at the beginning of the decade following the national unity (1861) with the laying of the first railway network. Italian literary reviews, reports and collections of books devoted to the discovery of the ethnographic and physical features of the new Italian Kingdom spread quickly. At the same time, journals and memories of individual trips confirmed the hints given by the relevant literature and provided new tips about the most celebrated tourist destinations which were further developed by the suggestions of the foreign writers living in Italy. In this literature, landscape descriptions depict the face of a big variety of shapes, colours and habits as well as the sense of the national belonging. This type of interpretation showed such features until the 1960s when it was overthrown by the deal of mass tourism.

THE EFFECT OF COLLEGIATE HEAD COACH’S GENDER ON FEMALE ATHLETE OUTCOMES
Creators: name: Carcagno, Simon George

Year: 2018

description: Previous research into the effect of collegiate head coach’s gender focused on measuring the coach’s ability to enhance athletic performance, this study extends that research by examining the coach’s educational and mentoring impact on athletes. We examined whether head coaching gender was associated with higher salaries, SWLS Satisfaction With Life Scores, UWES-9 Work Engagement Scores, JSS-18 Job Satisfaction Scores, and included an open-ended question exploring the impact of the head coach on the respondent’s career. Respondents scored highly in all measures, but these results were not associated with the coach’s gender. Analysis of the open-ended question for level of impact revealed that male and female coaches were equally likely to positively impact athlete’s careers, while male head coaches were significantly more likely to have a moderate positive impact. Analysis of the type of impact revealed that athletes with female head coaches were significantly more likely to report increased self-efficacy.
Dirac and Weyl Rings in Three Dimensional Cold Atom Optical Lattices

description: Recently three dimensional topological quantum materials with gapless energy spectra have attracted considerable interests in many branches of physics. Besides the celebrated example, Dirac and Weyl points which possess gapless point structures in the underlying energy dispersion, the topologically protected gapless spectrum can also occur along a ring, named Dirac and Weyl nodal rings. Ultra-cold atomic gases provide an ideal platform for exploring new topological materials with designed symmetries. However, whether Dirac and Weyl rings can exist in the single-particle spectrum of cold atoms remains elusive. Here we propose a realistic model for realizing Dirac and Weyl rings in the single-particle band dispersion of a cold atom optical lattice. Our scheme is based on previously experimentally already implemented Raman coupling setup for realizing spin-orbit coupling. Without the Zeeman field, the model preserves both pseudo-time-reversal and inversion symmetries, allowing Dirac rings. The Dirac rings split into Weyl rings with a Zeeman field that breaks the pseudo-time-reversal symmetry. We examine the superfluidity of attractive Fermi gases in this model and also find Dirac and Weyl rings in the quasiparticle spectrum.

Turismo per il paesaggio?

description: Mass tourism can destroy the sense of the landscape in areas of extraordinary value. Howether, if it is lead by curiosity towards diversity and by the search for a cultural and psychophysical enrichment, tourism can also act as a driving force for pursuing a balanced local development. While mass tourism entails, implicitly, the disruption of the landscape, some specific measures can be activated for promoting a “motivated” tourism as a driving force for local development and landscape valorisation.

description: Through their radio loudness, lack of thermal UV emission from the accretion disk and power-law dominated spectra, Low Luminosity AGN (LLAGN) display similarity with the hard state of stellar-mass black hole X-Ray Binaries (BHBs). In this work we perform a systematic hard X-ray spectral study of a carefully selected sample of unobscured LLAGN using archival $NuSTAR$ data, to understand the central engine properties in the lower accretion regime. We analyze the $NuSTAR$ spectra of a sample of 16 LLAGN. We model the continuum emission with detailed Comptonization models. We find a strong anti-correlation between the optical depth and the electron temperature of the corona, previously also observed in the brighter Seyferts. This anti-correlation is present irrespective of the shape of the corona, and the slope of this anti-correlation in the log space for LLAGN (0.68-1.06) closely matches that of the higher accretion rate Seyferts (0.55-1.11) and hard state of BHBs ($\sim$0.87). This anti-correlation may indicate a departure from a fixed disk-corona configuration in radiative balance. Our result, therefore, demonstrates a possible universality in Comptonization processes of black hole X-ray sources across multiple orders of magnitude in mass and accretion rate.

description: We investigate the orbital effects of strong external magnetic field on the ground state properties of a two dimensional holstein polaron, employing variational approaches based on the exact diagonalization (VAED). From the ground state energy and the wave function we calculate electron-phonon correlation function, the average phonon number and the Drude weight and investigate the evolution of a 2D holstein polaron as a function of the magnetic flux. Although the external magnetic field affects the polaron throughout the parameter regime, we show that the magnetic field has a stronger effect on a loosely bound (spatially extended) polaron. We also find that the magnetic field can be used as a tuning parameter, particularly for weakly coupled polaron, to reduce the spatial extent of a large polaron.

description: Ecotourism is a sector with strong potentials to address the entire tourism industry in the direction of the ecosystems conservation, Corporate Social Responsibility and Sustainable Development. In order to reach this complex challenge, organizations involved in the ecotourism sector should develop a systemic approach related to the organization, management and strategic process of ecotourism supply. To evaluate the effectiveness of an eco tourism system it is essential to have an overview on the different methodologies used to identify the successful experiences in this field.

description: The conference focused on the key role of research evidence for the design of policy and institutional innovations that accelerate the transformation to healthier, more sustainable, equitable, and resilient food systems. Research offers many important contributions to achieve the SDGs. It generates the basic inputs for innovations, i.e. policy and institutional innovations (incl. social and business innovations) as well as technology-based innovations to catalyze, support, and accelerate food systems transformation. Second, research assesses targets and actions by understanding the impliciations of various development pathways (for instance through quantitative analyses and food systems modeling) as well as assessing impacts ex-post to ensure learning and corrective measures. Taking a food systems approach that draws on expertise and evidence from different research disciplines is necessary to understand how investments and choices in food production, distribution, processing, and consumption determine outcomes related to nutrition, food security, socio-economic welfare, and environmental health. The conference demonstrated that high quality evidence is available even if there are still important gaps that need to be filled. The human and organizational capacity to generate evidence and innovation is also available if we can mobilize the financial resources and regional collaboration to address them. Of course, we must also use evidence to accelerate positive change. This is an important part of the “call to action” of this conference.

Beneath the Sheets: Elliott White Springs' Burlesque of Mid-Twentieth Century Advertising
Creators: name: Close, Avery
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: In the late 1940s and early 1950s, Colonel Elliott White Springs created an advertising campaign that shocked both the viewing public and advertising professionals alike. Instead of the typical, straightforward approach, Springs filled his advertisements with sexual innuendos, double entendres, and parodies to create a burlesque of the advertising industry. Although controversial, Springs’ provocative approach provides valuable insight into instances of social othering in American popular culture and advertising at the middle of the twentieth century. This thesis will compare Springs’ campaign to a variety of popular culture examples in order to reveal how Springs’ use of the parody makes evident the sociocultural ideologies manifested within the discourse of advertising.
