description: We combine SDSS and WISE photometry for the full SDSS spectroscopic galaxy sample, creating SEDs that cover lambda=0.4-22 micron for an unprecedented large and comprehensive sample of 858,365 present-epoch galaxies. Using MAGPHYS we then model simultaneously and consistently both the attenuated stellar SED and the dust emission at 12 micron and 22 micron, producing robust new calibrations for monochromatic mid-IR star formation rate proxies. These modeling results provide the first mid-IR-based view of the bi-modality in star formation activity among galaxies, exhibiting the sequence of star-forming galaxies (main sequence) with a slope of dlogSFR/dlogM*=0.80 and a scatter of 0.39 dex. We find that these new star-formation rates along the SF main sequence are systematically lower by a factor of 1.4 than those derived from optical spectroscopy. We show that for most present-day galaxies the 0.4-22 micron SED fits can exquisitely predict the fluxes measured by Herschel at much longer wavelengths. Our analysis also illustrates that the majorities of stars in the present-day universe is formed in luminous galaxies (~L*) in and around the green valley of the color-luminosity plane. We make the matched photometry catalog and SED modeling results publicly available.

The Power of Land Expropriation in the Federation of Ethiopia
Creators: name: Ganta, Brightman Gebremichael
Publisher: name: Bahir Dar University Journal of Law
Year: 2022

description: Although the power of land expropriation is arguably an inherent power (I claim it is a constitutional power) of a state in any jurisdiction, the approach, the manner and the source of it varies among nations and is also a point of academic and policy debate. Particularly, in federations, as is the case in Ethiopia, apart from its implication for land tenure security of landholders, it can be also a source of power conflict/competition between the central and state governments. However, the implication of the approach, the manner, and the source of land expropriation power adopted in the Ethiopian land law regime over the land tenure security and central state governments power conflict/competition have not been examined critically. Therefore, this study aims at setting the agenda for academic discourse and legal reform about the approach, the manner and the source of defining the power of land expropriation with the view to enhancing land tenure security and avoiding the potential power conflict/competition between the central and regional governments in the country.

The Insulating Nature of Na2IrO3: Mott-type or Slater-type?

description: We have investigated temperature-dependent electronic structures of Na2IrO3 to unravel its insulating nature. Employing the combined scheme of the density-functional theory (DFT) and the dynamical mean-field theory (DMFT), we have shown that the insulating state persists even above the Neel temperature (T_{N}), which reveals that Na2IrO3 is classified into a Mott-type insulator. The measured photoemission spectrum in the paramagnetic (PM) state is well described by the electronic structure obtained from the DFT+DMFT for the insulating state above T_{N}. The analysis of optical conductivity, however, suggests that the non-local correlation effect is also important in Na2IrO3. Therefore, Na2IrO3 is not to be a standard Mott insulator in that the extended nature and the non-local correlation effect of Ir 5d electrons are important as well in describing its electronic and magnetic properties.

description: Periodically driven quantum systems provide a novel and versatile platform for realizing topological phenomena. Among these are analogs of topological insulators and superconductors, attainable in static systems; however, some of these phenomena are unique to the periodically driven case. Here, we show that disordered, periodically driven systems admit an "anomalous" two dimensional phase, whose quasi-energy spectrum consists of chiral edge modes that coexist with a fully localized bulk - an impossibility for static Hamiltonians. This unique situation serves as the basis for a new topologically-protected non-equilibrium transport phenomenon: quantized non-adiabatic charge pumping. We identify the bulk topological invariant that characterizes the new phase (which we call the "anomalous Floquet Anderson Insulator", or AFAI). We provide explicit models which constitute a proof of principle for the existence of the new phase. Finally, we present evidence that the disorder-driven transition from the AFAI to a trivial, fully localized phase is in the same universality class as the quantum Hall plateau transition.

description: Thermodynamics of weakly screened (near the one-component-plasma limit) Yukawa fluids in two and three dimensions is analyzed in detail. It is shown that the thermal component of the excess internal energy of these fluids, when expressed in terms of the properly normalized coupling strength, exhibits the scaling pertinent to the corresponding one-component-plasma limit (the scalings differ considerably between the two- and three-dimensional situations). This provides us with a simple and accurate practical tool to estimate thermodynamic properties of weakly screened Yukawa fluids. Particular attention is paid to the two-dimensional fluids, for which several important thermodynamic quantities are calculated to illustrate the application of the approach.

This report is generated by the economic group for the commissioner's office and examines the critical issue of child food insecurity in Granville and Vance Counties in North Carolina. The contextual analysis evaluates teh current and historical socio-economic factors that contribute to food insecurity, a high-priority social determinant of health that has long-lasting impact on children's mental and physical health. A multifaceted approach was utilized for stakeholder mapping and engagement, analysis of past policies, and development of new potential policies. The design process utilized quality tools to develop the change idea, focusing on and enhancing the school meal program and enhancing local food access. The design process emphasized the feasibility, sustainability, and scalability of the school meal program by establishing a steering committee to oversee the implementation and iteration process. This comprehensive assessment aims to inform policy and practice to reduce child food insecurity and improve health outcomes.

description: Die zunehmende Anzahl mehrsprachiger Kinder in Grundschulklassen unterstreicht die Notwendigkeit innovativer didaktischer Konzepte zur Sprachförderung. Dies gilt nicht zuletzt im Hinblick auf die Aufgabe des Grundschulunterrichts, alle Kinder an Schriftkultur und konzeptionelle Schriftlichkeit heranzuführen. Vor diesem Hintergrund scheint sich das Angebot textfreier Bilderbuchgeschichten nicht unbedingt aufzudrängen. Dennoch geht aus langjährigen Beobachtungen in einer jahrgangsübergreifenden Lerngruppe der Klassen 1 bis 3 hervor, dass Schüler*innen die subtile narrative Komposition einer (fast) textlosen Bilderbuchgeschichte nicht nur wahrnehmen, sondern auch ihre Wertschätzung dafür zum Ausdruck bringen möchten. Am Beispiel von Erzählproduktionen zu Rotraut Susanne Berners Wimmelbüchern soll dieser Beitrag zeigen, wie die Buch-Rezeption Fähigkeiten zur Textgestaltung evozieren und mehrsprachige Kinder dazu einladen kann, (auch ihre eigenen) Geschichten zu erzählen.
description: The increasing number of multilingual children in primary school classes underlines the need for innovative didactic concepts for language promotion. This is true not least with regard to the task of primary school teaching to introduce all children to written culture and conceptual writing. Against this background, the offer of text-free picture book stories does not necessarily seem to impose itself. Nevertheless, long-term observations in an inter-grade learning group in grades 1 to 3 show that pupils not only perceive the subtle narrative composition of a (nearly) text-free picture book story, but also want to express their appreciation for it. Using the example of narrative productions on Rotraut Susanne Berner's Wimmelbücher, this paper aims to show how book reception can evoke text creation skills and invite multilingual children to tell (also their own) stories.

Legal Aspects of Multi-level Marketing (MLM) and Pyramid Schemes: Overview of the Ethiopian Legal Framework
Creators: name: Chane, Gizachew Silesh

description: The Multi-level marketing (also known as Network Marketing) has evolved as an alternative marketing strategy, modeled on the basic idea of the classical direct selling-the door-to-door selling. The MLM design compensates the door-to-door sellers not just for the sales they personally generate but for the sales generated by the people they recruit. This compensation scheme in MLM brought it close to pyramid scheme in design; makes it prone to abuse in the form of pyramid scheme. Indeed, it has been abusively used for operating pyramidal schemes; Regulators have been plagued with the problem of distinguishing MLM from pyramid scheme and sanctioning the misuses. No careful legal drafting is likely to provide a simple solution but reduces the perplexity in the factual analysis and enforcement decision making. The author in this article examined, using the doctrinal research method, the position of Ethiopian law regarding network marketing and how it deals with potential manipulation of network marketing for operating pyramid scheme. Ethiopian law on pyramidal scheme is drafted so generically and briefly, and without even mention of network marketing –the very mask in which pyramidal schemes operate. The researcher found out that such a design of Ethiopian law has resulted in legal uncertainty about the implication of operating MLM. Essential parametrizations of what is within the legal limit and when it is out there in the pyramid scheme are either vague or omitted. The author recommended the need for further elaborate rules on pyramid schemes and inclusion of some guiding standards on network marketing.

description: In this article, we develop a theory of integration on algebraic quantum groupoids in the form of regular multiplier Hopf algebroids, and establish the main properties of integrals obtained by Van Daele for algebraic quantum groups before - faithfulness, uniqueness up to scaling, existence of a modular element and existence of a modular automorphism - for algebraic quantum groupoids under reasonable assumptions. The approach to integration developed in this article forms the basis for the extension of Pontrjagin duality to algebraic quantum groupoids, and for the passage from algebraic quantum groupoids to operator-algebraic completions, which both will be studied in separate articles.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: Objectives: The main objective of this study is to assess change in practice of breastfeeding among HIV-positive mothers between 2003 and 2008/9. Methods: The study is based on analysis of the Kenya Demographic and Health Survey (KDHS) data for 2003 and 2008/9. In this study mothers with children age 0-23 months and had been tested for HIV are included from the KDHS data. Results: The Fisher’s exact tests and the logistic regression analysis show that in 2003, there was no association between HIV status and practice of breastfeeding. However, in 2008/9, HIV status of mothers has influenced current breastfeeding status. HIV-positive mothers are less likely to breastfeed their children in 2008/9 than 2003. Conclusions: Similar results are observed among mothers who may not know their HIV status (but their status are known to this investigation) and among mothers who know their HIV status. The sampled women’s breastfeeding practices are not in compliance with WHO’s recommendations which promote exclusive breastfeeding among HIV-positive mothers in resource-poor settings.

description: With the present study, we want to expand on the emerging research on state narcissism by means of two extensions, which we deem important: First, we will comprehensively examine the density distribution parameters for narcissistic states following the density distribution framework proposed by Fleeson (2001). Second, by relying on the NARC framework, we will disentangle agentic and antagonistic aspects of state narcissism (which has so far been examined as being unidimensional) by examining states of narcissistic admiration and rivalry and social status perception as their antecedent.
Functional studies on receptor-type protein tyrosine phosphatases of the R3 subgroup
Creators: name: Conn, Olga
Publisher: name: University of Westminster
Year: 2017

description: The receptor-type protein tyrosine phosphatases (RPTPs) of the R3subgroup play key roles in the immune, vascular and nervous system. They are characterised by an extracellular domain (ECD), comprised of multiple FNIII-like repeats, a transmembrane domain and a single intracellular phosphatase domain. Although their phosphatase domains have been Fstudied in detail the functional roles of their extracellular regions have not been clearly defined. Potential roles in ligand interaction, dimerisation and cell-cell contacts have been reported. Here I used a bimolecular fluorescence complementation (BiFC) assay in live cells to examine the molecular basis for the interaction of one of the R3 RPTP members, VE-PTP, with VE-cadherin, and explored the potential of others to interact with this protein. The potential of R3 RPTPs to homo-dimerise via extracellular domains in live cells was also addressed. Quantitative BiFC analysis using sialophorin (SPN), an unrelated membrane protein, and a membrane anchored C-terminal Venus-YFP (Myr-VC) fragment as controls revealed a specific interaction between VE-PTP and VE-cadherin using constructs expressing only the extracellular and transmembrane domains. Use of a deletion mutant indicated that, in contrast to previous studies, removal of the 17th FNIII-like domain of VE-PTP is not sufficient to disrupt this interaction. Other members of the R3 RPTP family (DEP-1, GLEPP1 and SAP-1) also exhibited the potential to interact with VE-cadherin suggesting that specificity of this protein-protein interaction is not determined by the ECD alone. The direct interaction of DEP-1 with VE-cadherin is likely to be of physiological relevance since both proteins are expressed in endothelial cells. GLEPP1 and SAP-1 exhibited homo-dimerisation, whereas DEP-1 and VE-PTP did not form dimers via their extracellular and/or transmembrane domains. SPN was identified as a possible bona fide ligand for DEP-1 and their interaction is likely to be of physiological relevance since they were both shown to regulate T cell receptor activation. The interactions identified in the present study suggest a role for both the extracellular domain and transmembrane domain of R3-PTPs in interaction with VE-cadherin. The study also highlights the importance of using multiple controls in BiFC experiments and quantitative analysis of results.
The Mandate of Charitable Organizations to Engage in Businesses as Income Generation Activity: Theories, International Experiences and Ethiopian Law
Creators: name: Abate, Yibekal
Publisher: name: Bahir Dar University Journal of Law
Year: 2022

description: The engagement of charitable organizations in business, as income generating activity, is a contentious subject. Those supporting charity trading see it as a venue of financial support for the missions of charities while others are against this move arguing that charity trading will degrade the defining virtues of charities – namely, that they operate outside of the for-profit marketplace. Theoretically, there are different lines of thought with regards to charity trading such as exclusivity doctrine, the doctrine of primary purpose trading, doctrine of ancillary trading, and the doctrine of non-primary purpose or unrelated trading. Countries adopt one or two of these theories and largely they view income generation activities from different perspectives– its relation with the primary purpose of the charity, asset protection of charities (the risk of business failure), and its effect on market competition. The Organization of Civil Societies Proclamation (OCS) of Ethiopia allows charities to engage in any lawful business activity without a condition of the element of relatedness to the mission of the charity and other concerns. Generally, there are doubts about the legitimacy and extent of engagement of charities in business. This article examines whether and to what extent, charities shall be allowed to engage in business activities. Following doctrinal research methodology, the article critically examined the theories, international practices, empirical evidences and legislations of non-profit organizations. Based on the analysis made the article concludes that as charities are inherently formed to pursue charitable purposes and since business activities as a secondary mission may distract them away from their central missions, their engagement in trade activities shall be limited only to charity purpose-related trading. Thus, the OCS law of Ethiopia needs to be re-visited in light of the foundational theories of the non-profit sector and major international experiences.

Creating Critical Dialogue with Gender and Sexual Minority and Ally Adolescents at HS High School through the use of Photovoice
Creators: name: Waters, Emily
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: During the spring of 2015, the Gay Straight Alliance (GSA) student group at HS high school will participate in a photovoice project to better understand gender and sexual minority (GSM) youth experiences at the school and advocate for a more inclusive environment for these populations. Compared to their cisgender or heterosexual peers, GSM adolescents are more likely to engage in risky behavior and experience poor health outcomes. GSM youth experience high rates of tobacco and other drug use, suicide, self-harm, sexually transmitted infections, and physical and sexual violence (Saewyc, 2011; Davis, Stafford, & Pullig, 2014; Goodenow, 2006). GSM youth experience discrimination in the form of homophobia and transphobia on all levels of the social context (Saewyc, 2011; Kuper, Coleman, & Mustanksi, 2013; Heck, Flentje, & Cochran, 2013). Many GSM youth experience some form of internalized homophobia and transphobia and shame around their identities (Kuper et al., 2013). Programs working with GSM youth often focus solely on the internal shame of GSM youth rather than focusing on their social environments. GSM youth are constantly weighing the benefits and consequences of disclosing their identity to others for fear of rejection, harassment, or violence (Kuper et al., 2013; Klein et al., 2014). Therefore, GSM youth more often experience fear of stigmatization and discrimination rather than feel shame about their identities (Klein et al., 2014). GSM youth experience high rates of discrimination and harassment within the school context. According to a 2013 National School Climate Survey conducted by Kocsiw, Greytak, Palmer, and Boesen (2014), 95% of the GSM youth in North Carolina had heard the word "gay" used in a negative way, 87% had heard other homophobic remarks (e.g., dyke, fag), and 81% heard negative remarks about gender expression. GSAs are student groups that provide social and emotional support to GSM students and their allies as well as advocate to create a more 2 inclusive and safe school environment (Heck et al., 2013; Mayberry, Chenneville, & Currie, 2011). The photovoice project described in this master's paper will collaborate with a GSA in a rural county in North Carolina to challenge the homophobia and transphobia in their school and wider community. Photovoice is a community-based participatory research method in which participants use photography to explore problems that affect their community and develop action steps to address those problems (Wang & Burris, 1997). The GSA will use a modified version of photovoice to 1.) Identify the unique challenges that GSM students at their high school experience, 2.) Create awareness on the homophobia and transphobia that exist within the school, and 3.) Enhance group cohesion and establish projects to continue to challenge the silence surrounding these issues in the school and community at large.
Einstein-Heisenberg Consistency Condition Interplay with Cosmological Constant Prediction in Resummed Quantum Gravity

description: We argue that our recent success in using our resummed quantum gravity approach to Einstein's general theory of relativity, in the context of the Planck scale cosmology formulation of Bonanno and Reuter, to estimate the value of the cosmological constant Λsupports the use of quantum mechanical consistency requirements to constrain the main uncertainty in that very promising result. This main uncertainty, which is due to the uncertainty in the value of the time t_{\text{tr}} at which the transition from the Planck scale cosmology to the FRW model occurs, is shown to be reduced, by requiring consistency between the Heisenberg uncertainty principle and the known properties of the solutions of Einstein's equations, from four orders of magnitude to the level of a factor of {\cal O}(10). This lends more credibility to the over-all resummed quantum gravity approach itself, in general, and to our estimate of $Λ$ in particular.

Expropriation of Urban Lands and its Implications for Tenure Security of Old Possessors
Creators: name: Gezahegn, Melaku
Publisher: name: Bahir Dar University Journal of Law
Year: 2022

description: One of the major issues that have come along with the re-enactment of the Ethiopian Urban Land Lease Proclamation Number 721/2011and that have triggered immense fear and worry among the public has been the clear determination of the government to convert all old possessions into a leasehold system. When an inquiry is made into the property right to land that old possessors acquired before and after the introduction of the leasehold system, and the implication of this proclamation is scrutinized in light of tenure security, there are issues that in fact are of great concern for old possessors. The most important issue that is underscored in this article is the dilemma that old possessors confront with regard to expropriation of old possession for ‘public purpose’. Accordingly, old possessions could easily be expropriated by land administrative organs under the guise of ‘public purpose’ which is stated broadly, and old possessors could also be given a substitute plot of land which is far smaller than its former size. They could also be given a substitute plot of land which is lower than its former grade and which is located in the outskirts of urban centers that may have the effects of disrupting social ties and the already established business activities of old possessors. Except for claims for compensation, old possessors are also prohibited from lodging an appeal to regular courts against any decisions of land administrative organs connected with issues of the law and claims for a substitute of a plot of land. The outcome of all these problems is nothing but to exacerbate the situation and to make old possessors live under acute conditions of tenure insecurity until the overall conversion of old possession into leasehold system is completed. This article will try to analyze those legislations dealing with expropriation of old possessors in light of tenure security issues.

description: The velocity function derived from large scale surveys can be compared with the predictions of LCDM cosmology, by matching the measured rotation velocities Vrot of galaxies to the maximum circular velocity of dark matter (DM) halos Vmax. For Vrot<50km/s, a major discrepancy arises between the observed and LCDM velocity functions. However, the manner in which different observational measures of Vrot are associated with Vmax is not straight forward in dwarf galaxies. We instead relate galaxies to DM halos using the empirical baryon- mass to halo-mass relation, and show that different observational measures of Vrot result in very different velocity functions. We show how the W50 velocity function, i.e. using the HI profile line width at 50% of peak HI flux to measure Vrot, can be reconciled with a LCDM cosmology. Our semi-empirical methodology allows us to determine the region of rotation curves that are probed by HI measurements (RHI), and shows that the Vrot of dwarfs are generally measured at a fraction of Rmax, explaining their tendency to have rising rotation curves. We provide fitting formulae for relating RHI and Reff (the effective radius) to the virial radius of DM halos. To continue to use velocity functions as a probe of LCDM cosmology, it is necessary to be precise about how the different measures of rotation velocity are probing the mass of the DM halos, dropping the assumption that any measure of rotational velocity can be equally used as a proxy for Vmax.

Sextic potential for $γ$-rigid prolate nuclei

description: The equation of the Bohr-Mottelson Hamiltonian with a sextic oscillator potential is solved for $γ$-rigid prolate nuclei. The associated shape phase space is reduced to three variables which are exactly separated. The angular equation has the spherical harmonic functions as solutions, while the $β$ equation is brought to the quasi-exactly solvable case of the sextic oscillator potential with a centrifugal barrier. The energies and the corresponding wave functions are given in closed form and depend, up to a scaling factor, on a single parameter. The $0^{+}$ and $2^{+}$ states are exactly determined, having an important role in the assignment of some ambiguous states for the experimental $β$ bands. Due to the special properties of the sextic potential, the model can simulate, by varying the free parameter, a shape phase transition from a harmonic to an anharmonic prolate $β$-soft rotor crossing through a critical point. Numerical applications are performed for 39 nuclei: $^{98-108}$Ru, $^{100,102}$Mo, $^{116-130}$Xe, $^{132,134}$Ce, $^{146-150}$Nd, $^{150,152}$Sm, $^{152,154}$Gd, $^{154,156}$Dy, $^{172}$Os, $^{180-196}$Pt, $^{190}$Hg and $^{222}$Ra. The best candidates for the critical point are found to be $^{104}$Ru and $^{120,126}$Xe, followed closely by $^{128}$Xe, $^{172}$Os, $^{196}$Pt and $^{148}$Nd.

Perspectives on Long-acting Reversible Contraceptives among Adolescent and Young Adult Women in the United States: A Qualitative Metasynthesis
Creators: name: Gray, Aria

Year: 2017

description: Background: Adolescent and young adult women in the United States (U.S.) are at increased risk for unintended pregnancy, yet utilization of long-acting reversible contraceptives (LARC) among this population is low. To improve understanding of LARC utilization in this population, this review aims to synthesize qualitative evidence exploring adolescent and young adult women’s perspectives on LARC utilizing methods of qualitative metasummary. Methods: After searching multiple electronic databases and reference lists, qualitative studies identifying determinants of LARC use among adolescents and young adults published between 2000–2017 were identified. Studies were selected if participants were U.S. adolescent or young adult women and the central focus of the study was about LARC use. The thematic analysis method of qualitative metasynthesis developed by Thomas and Harden was used to analyze, synthesize, and interpret the findings. Results: From 969 papers, 8 unique studies were included after several rounds of screening.. Study methodology included individual interviews (n = 8), focus groups (n = 3), and telephone interviews (n = 1), with several studies incorporating multiple qualitative data collection methodologies into their study design, including data from 144 U.S. adolescents and young women. Five main themes emerged from the studies of adolescent and young adult women’s perspectives on LARC: knowledge, contraceptive counseling, short-acting methods of contraception, individual needs, and fear and anxiety. Discussion: Adolescents and young adult women in the U.S. have varied views on LARCs. Participants expressed both positive and negative views of LARCs and valued different aspects of the methods in comparison to others. Participants also discussed a lack of knowledge of LARCs and the importance of the role of providers in contraceptive decision-making. These varied experiences and views should be taken into consideration in future work aimed at improving access to LARC for adolescents and young adult women.
Heroines, Anti-Heroines and New Women: The Early Drama of Michael Field, 1884-1895
Creators: name: Kirby, Johanna
Publisher: name: University of Westminster
Year: 2017

description: This thesis represents an analysis of five dramatic works by Katharine Bradley (1846-1914) and Edith Cooper (1862-1913) who wrote under the collaborative literary pseudonym “Michael Field” for nearly forty years from the late 1800s to their deaths. These are: Callirrhoë (1884), Fair Rosamund (1884), The Tragic Mary (1890), Stephania (1892), and Attila, My Attila! (1895). Although more recently Michael Field’s poetry has become the subject of more academic attention, here is currently little critical work on the Fields’ twenty-seven tragic dramas, and, as yet, no sustained analysis of individual plays. Over the course of five chapters, this thesis takes a new approach to these little known dramas and their eponymous heroines, carefully locating each one within both the context of the Fields’ lives, and the wider socio-cultural and political contexts which surround each play. It is the contention of this thesis, that through their dramatic writing, the Fields were engaging with a wide range of challenging issues, debates and concerns concerning the positioning and construction of middle-class female identity, role and sexuality. Through these analyses then, this study will consider the development of the Fields’ dramatic writing and identity as female dramatists within the wider social, cultural, literary, economic and political landscape.

description: One of the most disputed issues concerning the foetus particularly vis-à-vis the law on abortion is its personhood. While there is unanimity among scholars on the need to be definitive on what foetal personhood is, there abound diametrically opposing arguments about its legal status. It is imperative to resolve this conundrum because of the effect of the findings thereon on abortion debates. This is because if the foetus is regarded as a legal person abortion would be homicide, except in self-defence. If otherwise, the procedure may be legal, even on request. Thus, determining the status of the foetus is the starting-point for resolving most of the issues on the jurisprudence of abortion. It is against this backdrop that this article examines the laws of selected countries and international and regional instruments on the status of the foetus in comparison with women’s right to abortion. The article attempts to resolve the misgivings arising from the ascription to the foetus of certain pre-birth rights even while the foetus - the supposed bearer of those rights - is not yet born and in spite of the retention of the born-alive-rule in most legal systems. The article concludes that though the foetus is considered precious - even from conception - there is no basis for supposing that the foetus in-utero have inherent legal personality a fortiori the right to life as to reject women’s right to abortion unless such provision is otherwise unequivocally imputed into the law of a country.

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: Surface atomic-layer (SAL) superconductors consisting of epitaxially grown metal adatoms on a clean semiconductor surface have been recently established. Compared to conventional metal thin films, they have two important features: i) space-inversion symmetry breaking throughout the system and ii) high sensitivity to surface adsorption of foreign species. These potentially lead to manifestation of the Rashba effect and a Zeeman field exerted by adsorbed magnetic organic molecules. After introduction of archetypical SAL superconductor Si(111)-(root7xroot3)-In, we describe how these features are utilized to engineer topological superconductor with Majorana fermions, and discuss its promises and expected challenges.

An online parameter identification method for time dependent partial differential equations
Creators: name: Boiger, Romana

Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: Online parameter identification is of importance, e.g., for model predictive control. Since the parameters have to be identified simultaneously to the process of the modeled system, dynamical update laws are used for state and parameter estimates. Most of the existing methods for infinite dimensional systems either impose strong assumptions on the model or cannot handle partial observations. Therefore we propose and analyze an online parameter identification method that is less restrictive concerning the underlying model and allows for partial observations and noisy data. The performance of our approach is illustrated by some numerical experiments.
Mothers' Comfort with the Idea of Formula Feeding and Infant Feeding Intentions: Lessons from "Ready, Set, Baby" Prenatal Breastfeeding Education
Creators: name: Schildkamp, Paige
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Overview: Literature shows that lower comfort with the idea of formula feeding and higher breastfeeding intentions are associated with better breastfeeding outcomes, positively affecting both maternal and infant health. The study's objective was to evaluate if the "Ready, Set, BABY" (RSB) prenatal breastfeeding education session, offered during 2014-15 in the US and Puerto Rico, decreases a mother's comfort level with the idea of formula feeding and increases her breastfeeding intentions, particularly within populations with lower breastfeeding rates. Methods: Mothers' comfort with the idea of formula feeding and breastfeeding intentions were assessed pre- and post-RSB, via self-report questionnaires, using a 1 (very comfortable) - 8 (very uncomfortable) scale and the Infant Feeding Intention (IFI) Scale, respectively. Paired t-tests and logistic regression examined pre- to post-session changes. Results: Analysis showed significantly decreased comfort with the idea of formula and significantly improved IFI Scale scores in the US sample. IFI Scale score changes were also significant in the PR sample. Logistic regression analysis in the US showed that Hispanic women were 5.37 times as likely as non-Hispanic White women to have increased IFI Scale scores. Conclusion: RSB's success decreasing comfort with the idea of formula feeding and improving IFI Scale scores supports increasing availability of these prenatal breastfeeding education sessions to improve breastfeeding outcomes. Adding cultural competency to educator training and further tailoring RSB materials and sessions could better meet the needs of populations at high risk of early supplementation or breastfeeding cessation.

description: We report on the observation of the Josephson effect between two strongly interacting fermionic superfluids coupled through a thin tunneling barrier. We prove that the relative population and phase are canonically conjugate dynamical variables, coherently oscillating throughout the entire crossover from molecular Bose-Einstein condensates (BEC) to Bardeen-Cooper-Schrieffer (BCS) superfluids. We measure the plasma frequency and we extract the Josephson coupling energy, both exhibiting a non-monotonic behavior with a maximum near the crossover regime. We also observe the transition from coherent to dissipative dynamics, which we directly ascribe to the propagation of vortices through the superfluid bulk. Our results highlight the robust nature of resonant superfluids, opening the door to the study of the dynamics of superfluid Fermi systems in the presence of strong correlations and fluctuations.

description: The magnetic perturbation due to the ferromagnetic test blanket modules (TBMs) may deteriorate fast ion confinement in ITER. This effect must be quantified by numerical studies in 3D. We have implemented a combined finite element method (FEM) -- Biot-Savart law integrator method (BSLIM) to calculate the ITER 3D magnetic field and vector potential in detail. Unavoidable geometry simplifications changed the mass of the TBMs and ferritic inserts (FIs) up to 26%. This has been compensated for by modifying the nonlinear ferromagnetic material properties accordingly. Despite the simplifications, the computation geometry and the calculated fields are highly detailed. The combination of careful FEM mesh design and using BSLIM enables the use of the fields unsmoothed for particle orbit-following simulations. The magnetic field was found to agree with earlier calculations and revealed finer details. The vector potential is intended to serve as input for plasma shielding calculations.

Religion, Religiosity and the Contraception Mandate
Creators: name: Garand, Kate
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Objectives. To determine if religious affiliation and religiosity influence an individual's opinion concerning the Health and Human Services contraception mandate. Methods. A secondary analysis was conducted using a February 2012 data set from Pew Research Center. Responses from 794 individuals were analyzed in a logit model with support for an exemption to the contraception mandate as the dependent variable and religious affiliation and religiosity, measured by church attendance, as the independent variables. Results. Religious affiliation is not statistically associated with support for the exemption. In contrast, there is a positive and statistically significant relationship between religiosity and support for an exemption. Conclusions. Religiosity has a greater influence on an individual's support for an exemption to the contraception mandate than religious affiliation.
