description: Within the framework of the study of radiative corrections to the polarization observed in elastic $ed$-scattering in leptonic variables have been calculated the Born values of vector AB^L, AB^T and tensor AB^LL, AB^TT, AB^LT asymmetries. The deuteron wave functions in coordinate representation for eight nucleon-nucleon potentials (Nijm1, Nijm2, Nijm93, Reid93, Argonne v18, OBEPC, MT and Paris) have been used for numerical calculations of vector AB^i(p,teta) and tensor AB^ij(p,teta) asymmetries. The angular-momentum dependence of values vector and tensor asymmetries have been also evaluated in 3D format for Reid93 potentials.

description: Since stars retain signatures of their galactic origins in their chemical compositions, we can exploit the chemical abundance distributions that we observe in stellar systems to put constraints on the nature of their progenitors. In this thesis, I present results from three projects aimed at understanding how high resolution spectroscopic observations of nearby stellar systems might be interpreted. The first project presents one possible explanation for the origin of peculiar abundance distributions observed in ultra-faint dwarf satellites of the Milky Way. The second project explores to what extent the distribution of chemical elements in the stellar halo can be used to trace Galactic accretion history from the birth of the Galaxy to the present day. Finally, a third project focuses on developing an input optimization algorithm for the second project to produce better estimates of halo accretion histories. In conclusion, I propose some other new ways to use statistical models and techniques along with chemical abundance distribution data to uncover galactic histories.

description: This study explored the interplay between early learning and development standards (ELDS) and emergent bilingual learners (EBLs) in PreK classrooms in Boston, Massachusetts. The study explored how preschool teachers and policy experts understand ELDS, and how teachers integrate ELDS with their practice generally, and specifically with regard to EBLs. To do so, it sought to understand the ways in which EBLs are positioned in Massachusetts’ ELDS; how ELDS are understood, perceived, and enacted in general education, sheltered English immersion (SEI), and dual language PreK classrooms; and how state and district level education policy experts perceive the relationships between Massachusetts language policy, ELDS, and the needs of young EBLs. The study contextualized ELDS within a sociocultural framework in order to provide an understanding of the role of standards in the early education of EBLs. Employing qualitative interviews and a review of ELDS documents, the study was situated within the context of the Massachusetts 2002 Question 2 legislation, which banned bilingual education and instead instituted SEI classrooms. The researcher found that Vygotsky and Rogoff’s sociocultural theories of learning were helpful in framing understandings of ELDS in their development and in practice. Using this lens allowed for depth in understanding the power dynamics in the development of ELDS, including reflecting on the dominant benchmarks considered in the writing of standards. As part of a systemic approach to educational equity, ELDS should be carefully reviewed within the context of a Eurocentric orientation in order to influence their nature. Using a sociocultural theoretical lens also allowed for depth in understanding ELDS implementation, including how children’s native languages and cultures are impacted by perceptions of EBL ability and achievement. The study offers suggestions including: reviewing and consolidating standards; changes to education and professional development (pre-service and in-service); policy changes in entry procedures for EBLs; more nuanced understandings of the inherent biases that undergird serving this population equitably; a heteroglossic view of dual language assessments; increasing workforce diversity; supporting paraprofessionals; improved communication with families; increased monitoring and feedback of ELDS; reconciling state and district early childhood work expectations; and an increased policy focus on EBLs.
Gradient corrections for semiclassical theories of atoms in strong magnetic fields

Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: This paper is divided into two parts. In the first one the von Weizsäcker term is introduced to the Magnetic TF theory and the resulting MTFW functional is mathematically analyzed. In particular, it is shown that the von Weizsäcker term produces the Scott correction up to magnetic fields of order $B \ll Z^2$, in accordance with a result of V. Ivrii on the quantum mechanical ground state energy. The second part is dedicated to gradient corrections for semiclassical theories of atoms restricted to electrons in the lowest Landau band. We consider modifications of the Thomas-Fermi theory for strong magnetic fields (STF), i.e. for $B \ll Z^3$. The main modification consists in replacing the integration over the variables perpendicular to the field by an expansion in angular momentum eigenfunctions in the lowest Landau band. This leads to a functional (DSTF) depending on a sequence of one-dimensional densities. For a one-dimensional Fermi gas the analogue of a Weizsäcker correction has a negative sign and we discuss the corresponding modification of the DSTF functional.

description: The problems related to the management of large quantum registers could be handled in the context of distributed quantum computation: unitary non-local transformations among spatially separated local processors are realized performing local unitary transformations and exchanging classical communication. In this paper, we propose a scheme for the implementation of universal non-local quantum gates such as a controlled-$\gate{NOT}$ ($\cnot$) and a controlled-quantum phase gate ($\gate{CQPG}$). The system we have chosen for their physical implementation is a Cavity-Quantum-Electro-Dynamics (CQED) system formed by two spatially separated microwave cavities and two trapped Rydberg atoms. We describe the procedures to follow for the realization of each step necessary to perform a specific non-local operation.

Re-Evaluating Small Long-Period Confirmed Planets From Kepler

description: We re-examine the statistical confirmation of small long-period Kepler planet candidates in light of recent improvements in our understanding of the occurrence of systematic false alarms in this regime. Using the final Data Release 25 (DR25) Kepler planet candidate catalog statistics, we find that the previously confirmed single planet system Kepler-452b no longer achieves a 99% confidence in the planetary hypothesis and is not considered statistically validated in agreement with the finding of Mullally et al. (2018). For multiple planet systems, we find that the planet prior enhancement for belonging to a multiple planet system is suppressed relative to previous Kepler catalogs, and we identify the multi-planet system member, Kepler-186f, no longer achieves a 99% confidence in the planetary hypothesis. Because of the numerous confounding factors in the data analysis process that leads to the detection and characterization of a signal, it is difficult to determine whether any one planetary candidate achieves a strict criterion for confirmation relative to systematic false alarms. For instance, when taking into account a simplified model of processing variations, the additional single planet systems Kepler-443b, Kepler-441b, Kepler-1633b, Kepler-1178b, and Kepler-1653b have a non-negligible probability of falling below a 99% confidence in the planetary hypothesis. The systematic false alarm hypothesis must be taken into account when employing statistical validation techniques in order to confirm planet candidates that approach the detection threshold of a survey. We encourage those performing transit searches of K2, TESS, and other similar data sets to quantify their systematic false alarms rates. Alternatively, independent photometric detection of the transit signal or radial velocity measurements can eliminate the false alarm hypothesis.

description: Given the position of school districts within the education ecosystem, superintendents are important to educational leadership discussions, particularly systems change or improvement discourse. Superintendents manage operations, oversee policy implementation, and affect the climate as well as strategic direction of multimillion-dollar school district organizations. Additionally, superintendents manage district staff and liaise with a governance body towards maximizing student outcomes as they are accountable for educating millions of students in the United States. Nevertheless, the district chief executive is under researched in education leadership literature. Moreover, superintendent identity is overlooked within education leadership research. This dissertation argues the lack of research centered on superintendents’ perceptions of themselves as school district administrators precludes a full appreciation of the superintendency. Further, without consideration of superintendent identity, theories of transformation and effective district leadership are incomplete. Thus, this dissertation’s purpose is to present results from an investigation of six White Massachusetts school district superintendents’ self-perceptions and role expectations. In addition, this dissertation study considered influences on these superintendents’ identities and leadership practices. This qualitative study, informed by phenomenological research methods, utilized the lens of identity theory to understand these participants as superintendents. From this research investigation, the findings revealed participants’ primary self-perception as superintendent was leader. Within this study, participants described superintendent identity in terms of state, district and local community contexts as promoting student achievement. Participants in this research investigation revealed they grappled with a tension resulting from connecting their self-concept to superintendent identity. Further, this study provides these superintendents’ self-perceptions and role expectations associated with education reform. In conclusion, this study extends the discourse regarding superintendent leadership while offering three major research contributions with implications for policy and practice: (1) a description of superintendent identity, including these superintendents’ characterizations of internalized role expectations, and self-perceptions as possible explanations of their leadership practices and; (2) conceptualizations of superintendent leadership of education reform from a sample of district chief executives, including that of filter or buffer; (3) a framework for understanding the superintendent through the lens of superintendent identity.
Understanding the Present: The Representation of Contemporary History in Ludwig Börne, Heinrich Heine, and Georg Büchner
Creators: Swellander, Michael
Publisher: name: Columbia University
Year: 2019
Subjects: German literature
History in literature

description: Understanding the Present examines the thematization of the historical present in nineteenth-century German literary texts. In theorizations of political literature, such as Jean-Paul Sartre’s writings on “committed literature,” an emphatic concept of the present is a given. Of course, the present is a notoriously elusive temporality. The texts discussed in this dissertation, rather than focusing on accurate sociological representations of the present or an intensive rhetorical engagement in its political discourse, interrogate how the present can be evoked in literature in the first place. Understanding the Present discusses the forms privileged by certain authors in the representation of the present – prose, periodicals, drama – as well as the paradoxes such approaches posed. Rather than discussing these texts in terms of “operative literature” or “committed literature,” which has been a trend in scholarship since the 1960s, this dissertation approaches the nineteenth century from the perspective of so-called Gegenwartsliteratur. It does not claim the successful or unsuccessful political intervention of these texts, but rather shows how their authors imagined a literary intervention in the political present could occur at all.
      	Chapter one shows Ludwig Börne’s popular magazine Die Wage: Eine Zeitschrift für Bürgerleben, Wissenschaft und Kunst, not only as surreptitiously carrying barbs against state-sanctioned censorship, as is most common in studies of the periodical, but as following a program of political historiography. Börne’s text is therefore subversive at a structural level and presents a poetics of representing the present. Chapter two shows how Heinrich Heine used the republication of his political journalism to reflect on the essential dynamic of understanding the present whereby one can only comprehend contemporary events with reference to the past and future. Georg Büchner’s drama, Dantons Tod, the subject of chapter three, presents a paradox similar to Heine’s, but through a little observed aspect of his citational practice, which I call “internal citation.”  By showing his characters wittingly and unwittingly quoting each other in the play and repeating certain gestures, Büchner draws out ambiguities of authorship in political discourse and raises important questions about the experience of the present. Together, these three texts contribute to the study of political literature by interrogating the central notion of the emphatic present in it.

We numerically reproduce the Wyman solution and generate new solutions for the case where the theory has a nontrivial fundamental length scale μ^{-1}. By considering spherically symmetric perturbations of these solutions we show that the Wyman solutions are generically unstable.

We exemplify the phenomenon with a nonlinear reaction-diffusion equation in a two-dimensional undulated domain. Concepts from the theory of dynamical systems, and a transverse-single-mode approximation are used to describe the spatially chaotic structures.

description: Labor market projections see a growing need for nurses to satisfy demand in the U.S. health care sector into the next few decades. It is assumed that this demand will be met in part by immigrant nurses who received their nursing education outside the United States. Like many immigrants to the United States, internationally educated nurses face a number of challenges that make it difficult for them to obtain a nursing license and practice nursing in a U.S. health care setting. Learning to surmount these barriers represents a learning and a coping process.This qualitative case study was designed to explore how a sample of internationally educated nurses learned to reenter the nursing profession in the U.S. The participants consisted of alumni of a retraining program for internationally trained health care professionals housed in a community college in the Northeastern United States. The primary sources of data came from semi-structured interviews consisting of questions about their experiences pursuing reentry into the nursing profession. The study’s major findings included the following: (1) Participants described being dissatisfied with their initial employment upon immigrating to the United States. (2) Participants reported that the language barrier and the nursing certification process, including the licensure exam, were major challenges to reentering the profession. (3) Participants reported that the most important things they learned were the difference between nursing practice in their countries of origin and in the U.S., and professional skills, including National Council Licensure Examination (NCLEX) test-taking skills. (4) Participants reported that they learned in both informal and formal methods. (5) Participants reported that having a positive attitude, support from others, and time management enabled their learning, while gaps in their practice hindered it.The findings of the study suggest that the participants learned to surmount the barriers they faced through a learning process characterized by increasing professional autonomy and self-directedness, as well as critical reflection on prior education and training. This process is facilitated by educators who are able to both help them develop professional autonomy and provide emotional support along what is a difficult and prolonged journey toward RN licensure.
Null weak singularities in plane-symmetric spacetimes

description: We construct a new class of plane-symmetric solutions possessing a curvature singularity which is null and weak, like the spacetime singularity at the Cauchy horizon of spinning (or charged) black holes. We then analyse the stability of this singularity using a rigorous non-perturbative method. We find that within the framework of (linearly-polarized) plane-symmetric spacetimes this type of null weak singularity is locally stable. Generically, the singularity is also scalar-curvature. These observations support the new picture of the null weak singularity inside spinning (or charged) black holes, which is so far established primarily on the perturbative approach.

Identification Problems In The Social Sciences

Year: 1992
Subjects: Research Methods/ Statistical Methods

description: Methodological research in the social sciences aims to learn what conclusions can and cannot be drawn given empirically relevant combinations of assumptions and data. Methodologists have long found it useful to separate inferential problems into statistical and identification components. Studies of identification seek to characterize the conclusions that could be drawn if the researcher had available a sample of unlimited size. Studies of statistical inference seek to characterize the generally weaker conclusions that can be drawn given a sample of positive but finite size. Statistical and identification problems limit in distinct ways the conclusions that may be drawn in empirical research. Statistical problems are most severe when the available sample is small. Identification problems are most severe when the researcher knows little about the population under study and the sampling process yields only weak data on the population. This paper synthesizes some of my recent research and thinking on identification problems in the social sciences. Four problems are discussed: extrapolation of regressions, the selection problem, identification of endogenous social effects from outcome data, and identification of subjective phenomena. These problems arise regularly in social science research and are the source of many substantive disputes.

description: Though we have called it the Harappan Timeline, it concerns the entire Indus-Sarasvatī archaeological complex, or what has also been called the Greater Indus Valley, or what the Reich-Narsimhan study has called the Indus Periphery; though Reich-Narsimhan’s Indus Periphery may extend beyond Greater Indus Valley, as it includes all those “who were in cultural contact with the Indus Valley Civilisation”. Going forward, for the sake of brevity, we shall often use the term Harappan to refer to the Greater Indus Valley. The purpose of the timeline is to get some clues for dating the major inflows of communities relevant to Kōṁkaṇ - the kṣatrīya, the kirāt and the brāmhaṇ. Along with the dating, we are also interested in gaining further insight into their origin and the route they followed.

Photoevaporation of Molecular Gas Clumps Illuminated by External Massive Stars: Clump Lifetimes and Metallicity Dependence

description: We perform a suite of 3D radiation hydrodynamics simulations of photoevaporation of molecular gas clumps illuminated by external massive stars. We study the fate of solar-mass clumps and derive their lifetimes with varying the gas metallicity over a range of $10^{-3} \,Z_\odot \leq Z \leq Z_\odot $. Our simulations incorporate radiation transfer of far ultraviolet (FUV) and extreme ultraviolet (EUV) photons, and follow atomic/molecular line cooling and dust-gas collisional cooling. Nonequilibrium chemistry is coupled with the radiative transfer and hydrodynamics in a self-consistent manner. We show that radiation-driven shocks compress gas clumps to have a volume that is set by the pressure-equilibrium with the hot ambient gas. Radiative cooling enables metal-rich clumps to condense and to have small surface areas, where photoevaporative flows are launched. For our fiducial set-up with an O-type star at a distance of 0.1 parsec, the resulting photoevaporation rate is as small as $\sim 10^{-5} M_{\odot}/{\rm yr}$ for metal-rich clumps, but is larger for metal-poor clumps that have larger surface areas. The clumps are continuously accelerated away from the radiation source by the so-called rocket effect, and can travel over $\sim$1 parsec within the lifetime. We also study photoevaporation of clumps in a photo-dissociation region. Photoelectric heating is inefficient for metal-poor clumps that contain a smaller amount of grains, and thus they survive for over $10^5$ years. We conclude that the gas metallicity strongly affects the clump lifetime and thus determines the strength of feedback from massive stars in star-forming regions.
Understanding the Security Community in Thailand: How to Improve Human Rights Education for Thai Security Personnel

description: This research critically engages challenges for the integration or incorporation of human rights issues and values into education and training for Thai security personnel. Concerned stakeholders, both public and private, have been invested in human rights education and training within the security sector, especially for authorities working in the Southern Border Provinces of the country, where violent incidents sporadically occur and the situation of human rights violations, including by state authorities, is of concern. However, limited research and attention has been paid on how such interventions have their effects on learners. With the Accountability – Professional Development Model as the main conceptual framework of this study, it draws on empirical evidence and comparative examples from different human rights education and training programs in different parts of the world and further delves into the subjective experiences of both trainers and participants engaged in the training, especially in the context of Southern Border Provinces. This study reveals both contextual challenges and practical difficulties at every stage of the training, from design and implementation to follow up and evaluation. Critical obstacles that hinder the efforts of the human rights training revolve around the problem of organizational and learning culture of the security forces, skepticisms, and resistance of learners toward human rights ideas and organizations in the area, the distinctive characters, and irrelevancy of the training contents as deemed by learners, among others. Despite the prevailing challenges, the research sheds light on several cases where learners demonstrate how the training made a meaningful contribution to their professional roles and empowered their intrinsic advocacy for human rights. By tapping on opportunity suggested by these cases, the study proposes thoughts and ways forward for the improvement of education and training efforts to achieve the ultimate goals in putting an end to human rights violations by security personnel.

description: We test the ability of strong lensing data to constrain the size of a central core in the dark matter halos of galaxy clusters, using Abell 611 as a prototype. Using simulated data, we show that modeling a cluster halo with ellipticity in the gravitational potential can bias the inferred mass and concentration, which may bias the inferred central density when weak lensing or X-ray data are added. We also the highlight the possibility for spurious constraints on the core size if the radial density profile is different from the assumed model. These systematics can be ameliorated if central images are present in the data. Applying our methodology to Abell 611 and imposing a reasonable prior on the stellar mass-to-light ratio restricts the core size to be less than about 4 kpc, with a minimum reduced $χ^2$ of 0.28 for 0."2 positional errors. Such small cores imply a constraint on the dark matter self-interaction cross section of the order of $0.1\ \mathrm{cm^2/g}$ at relative velocities of about 1500 km/s.

description: Direct measurements of the velocity in turbulent convection of $SF_6$ near its gas-liquid critical point by light scattering on the critical density fluctuations were conducted. The temperature, velocity and cross frequency power spectra in a wide range of the Rayleigh and Prandtl numbers show scaling behaviour with indices, which are rather close to the Bolgiano-Obukhov scaling in the wavenumber domain.

description: Digital image processing includes an important approach related to image filtering that leads to image enhancement. In general, Images may get noisy according to various reasons, in such situations; the filtering approach of images is the key for smoothing and sharpening process. In this paper, we proposed a filtering technique related to the frequency domain for both lowpass and highpass filters. The idea of the proposed filter can be described in two cases, in case of lowpass filter, we set the values of the bright objects in the spectrum to ones, and the rest of them to zeros, in case of highpass filter, we set the values of the bright object in the spectrum to zeros, and the rest of them to ones. The proposed technique can estimates the perfect match on the image spectrum resulting from Fourier Transform. This technique is to cover the intensity levels starting from the initial coordinates at the center toward the various directions of the spectrum. The Intensity levels appear in various distributions and it depend on the transformed image spectrum. We can see the image spectrum as an intensity image in a spatial domain, we want to segment it in order to detect the bright objects or the low frequency in the spectrum. We have segmented the image using Otsu method, which used to define the location of low frequencies. The segmented image will be used as a lowpass and highpass filters.
Understanding the Role of Cultural Values in the Experience of Work-Family Conflict Among Professional Latinas
Creators: Gelder, Karen M.
Publisher: name: Columbia University
Year: 2012
Subjects: Counseling psychology

description: The majority of empirical work regarding the phenomenon of work-family conflict has focused on the experiences of White, middle-class, professional women. While Latinos represent the fastest growing segment of workers in the U.S. labor force, and professional employment the fastest growing segment of occupation type, the experiences of professional Latinas, for whom the dominant cultural values may not be salient, remains largely unexplored. The influence of cultural context variables on experiences of work-family conflict has yet to be understood. The present study surveyed 203 professional Latinas with children. It was expected that Latino cultural values (i.e., collectivism, familism) and traditional gender role attitudes (i.e., marianismo)  would have both a main effect on levels of work-family conflict and a moderating effect on the relationship between job and family stressors and work-family conflict, such that the relationship between both kinds of stressors and the two forms of conflict (i.e. work-family conflict; family-work conflict) would be stronger for those participants who also endorsed greater levels of individualism and familism, and for those who adhered to more traditional gender role attitudes and who experienced greater conflict in relation to their gender role attitudes. As expected, hierarchical multiple regressions revealed significant main effects for job and family stressors and individualism on levels of work-family conflict. Contrary to the hypotheses, no main effects were found for collectivism, familism, or gender role attitudes. Also as expected, results indicated that collectivism appeared to moderate the relationship between family stressors and family-work conflict and familism moderated the relationships between job and family stressors and work-family conflict. Contrary to hypothesized relationships, results did not reveal a significant moderating effect for gender role attitudes. However, as predicted , the level of conflict that participants reported experiencing in regards to their gender role attitudes did appear to significantly moderate the relationship between job and family stressors and work-family conflict, such that these relationships were stronger for those participants who endorsed high levels of conflict about their gender role attitudes. Implications of these findings for future research, training, and practice were discussed.

A handlebody calculus for topology change

description: We consider certain interesting processes in quantum gravity which involve a change of spatial topology. We use Morse theory and the machinery of handlebodies to characterise topology changes as suggested by Sorkin. Our results support the view that that the pair production of Kaluza-Klein monopoles and the nucleation of various higher dimensional objects are allowed transitions with non-zero amplitude.

description: Maintaining fluid balance is essential for sustaining a variety of bodily functions, such as metabolic and biochemical processes, nutrient transport, and thermoregulation. In adults, approximately 65% of body mass consists of fluids, with this percentage being slightly lower in females than in males. Body fluids are divided into two main compartments: intracellular and extracellular fluid compartments.

description: The University of British Columbia UBC is preparing a new Green Building Plan to define strategies so future buildings will fulfill its commitment to sustainable development. Knowing what other sustainable leaders are doing to make their campuses sustainable is very beneficial to help UBC to achieve as best of a Green Building Plan as possible. To compare green building policies, this report summarizes developments strategies used in universities of Calgary, Harvard and Plymouth, analyze the strength and weakness of some of the strategies and discuss pros and cons of strategies for UBC use. We included recommended policies and practices worthy of further investigation by UBC.

description: For the radial motion of massive particles with large angular momenta in Schwarzschild geometry and that of massive charged particles with large angular momenta or energy in a particular range in Reissner--Nordström geometry, there exist classically forbidden regions on the outside of the respective event horizons which scatter certain infalling geodesics or screen some of the black holes' evaporation by reflecting the emitted particles back into the black holes. Quantum tunneling across this forbidden regions is studied.
