title: Caterpillars and Catalysts: A longitudinal Case Study of Writing Development in an Early Years Classroom Privileging Dramatic Pedagogies
Creators: name: Harden, Annette
Publisher: name: Griffith University
Year: 2013
Subjects: subject: Drama in education
subject: Puppetry
subject: Literacy, Primary school

description: This thesis explores the impact on children’s development in a preparatory school classroom, when dramatic pedagogies were privileged in the teaching of writing. Using a qualitative case study approach, which included a selection of five illustrative cases, children’s progress from role-play to phonetic users of the alphabet was examined. Data included the artefacts produced by the children, reading records, a journal of the year, and the transcripts of videos made of teaching sessions. A self-study of the researcher as an emerging drama teacher was included in the multi-case study, alongside the literacy stories of Edward, Lucy, James and Martin, all of whom were four years old at the beginning of the school year. The pedagogy included guided drama and puppetry events in which new aspects of literacy understanding and skill were progressively inserted. These events were followed by dramatic play periods where the sets, props, costumes and literate tools were freely available for the children’s use. Children were explicitly taught alphabetic skills with a synthetic, phonetic approach, and were encouraged to employ these skills for authentic and meaningful purposes within the drama events and in subsequent dramatic play.

description: We investigate the spectral response of a Brillouin amplifier in the frequency regime within the SBS bandwidth. This is done by amplitude modulating the pump with a low frequency, and therefore, unlike previous studies, the spectrum of the modulated pump is, in all cases, smaller than the SBS bandwidth. We show both theoretically and experimentally that unlike phase modulation, which was reported in the literature, the amplitude modulation increases the Brillouin amplifier gain, and that this effect has a very narrow bandwidth. Only modulation frequencies that are lower than a certain cut-off frequency increase the gain. This cut-off frequency is inversely proportional to the fiber's length, and can therefore be arbitrarily small.

Direct Jet Reconstruction in Proton-Proton and Copper-Copper Collisions at √sNN = 200 GeV
Creators: Lai, Yue Shi
Publisher: name: Columbia University
Year: 2012
Subjects: Nuclear physics

description: Collision of heavy nuclei at the Relativistic Heavy Ion Collider (RHIC) recreates the state of high temperature quark-gluon plasma that existed shortly after the Big Bang. Measurement using single particle spectra and two-particle correlation shows that this medium is largely opaque to the transit of a high energy quark or gluon. Reconstructing the kinematics of these quarks and gluons can provide additional constraints for the property of their interaction with the medium. While the direct reconstruction of quantum chromodynamics jets, the final state showers of quarks and gluons, has become an indispensable tool at hadron and electron accelerator experiments, the application of this technique to heavy ion collisions at the RHIC energy has been considered a hard problem. The relatively low yield of high transverse momentum jets would have to be detected within a large, fluctuating background that can give rise to a false jet signal. At the RHIC PHENIX experiment, jet reconstruction also has to cope with the limited aperture of the central arm spectrometers. To overcome both problems, which can distort the jet signal in the traditional reconstruction algorithms, this thesis develops an algorithm that reconstructs the jets as maxima of the Gaussian filtered event transverse momentum distribution. The Gaussian angular weighting causes the algorithm to become more sensitive to the jet core versus the jet periphery. It is then combined with a fake jet rejection discriminant to remove the background fluctuation from the jet signal. This algorithm is used to obtain the first jet measurement in heavy ion environment at PHENIX, using data from the 2004/2005 RHIC run. The result includes the proton-proton inclusive jet spectrum, the proton-proton fragmentation function, the copper-copper jet nuclear modification factor, the copper-copper jet central-to-peripheral modification factor, and the copper-copper dijet azimuthal correlation. The measured copper-copper jet nuclear modification factor shows that there is a significant initial state effect to the jet suppression. The observation of no broadening in the copper-copper dijet azimuthal correlation indicates that the traditional energy loss picture via multiple soft scattering may not be applicable to the quark-gluon plasma.
Directed Evolution of Protein Receptor Binding for Small Molecule Therapeutics Using Fluorescence Polarization

description: The field of metabolic engineering focuses on using molecular biology tools to genetically modify the metabolic pathways of cells for the production of chemical compounds. The field of directed evolution can alter the native abilities of proteins by taking inspiration from natural evolution. Both fields bring novel solutions to current problems in energy, the environment, and medicine. However, there is still no general higher throughput screening method for both of these fields. In this dissertation, we apply our designed fluorescence polarization assay to fill this need in the fields of metabolic engineering and directed evolution. Chapter 0 gives background information related to metabolic engineering, directed evolution, tetracyclines, the Tetracycline Repressor protein (TetR), TAN-1612, and fluorescence polarization. Chapter 1 describes our development of a quantitive, sensitive, and fast fluorescence polarization assay which uses the TetR protein to detect the binding of the small molecule tetracycline TAN-1612. Chapter 2 demonstrates that the binding affinity of the TetR protein for TAN-1612 can be improved using directed evolution and by incorporating our assay to screen TetR mutants. Finally, in Chapter 3 we apply our fluorescence polarization assay to the screening of yeast strains biosynthesizing TAN-1612, without the need of time and labor intensive extraction and purification steps.

description: A Filbert matrix is a matrix whose (i,j) entry is 1/F_(i+j-1), where F_n is the nth Fibonacci number. The inverse of the n by n Filbert matrix resembles the inverse of the n by n Hilbert matrix, and we prove that it shares the property of having integer entries. We prove that the matrix formed by replacing the Fibonacci numbers with the Fibonacci polynomials has entries which are integer polynomials. We also prove that certain Hankel matrices of reciprocals of binomial coefficients have integer entries, and we conjecture that the corresponding matrices based on Fibonomial coefficients have integer entries. Our method is to give explicit formulae for the inverses.

description: In this paper, we introduce a novel semantic description approach inspired on Prototype Theory foundations. We propose a Computational Prototype Model (CPM) that encodes and stores the central semantic meaning of objects category: the semantic prototype. Also, we introduce a Prototype-based Description Model that encodes the semantic meaning of an object while describing its features using our CPM model. Our description method uses semantic prototypes computed by CNN-classifications models to create discriminative signatures that describe an object highlighting its most distinctive features within the category. Our experiments show that: i) our CPM model (semantic prototype + distance metric) is able to describe the internal semantic structure of objects categories; ii) our semantic distance metric can be understood as the object visual typicality score within a category; iii) our descriptor encoding is semantically interpretable and significantly outperforms other image global encodings in clustering and classification tasks.

description: The thalamus is the major gate to the cortex and its control over cortical responses is well established. Cortical feedback to the thalamus is, in turn, the anatomically dominant input to relay cells, yet its influence on thalamic processing has been difficult to interpret. For an understanding of complex sensory processing, detailed concepts of the corticothalamic interplay need yet to be established. Drawing on various physiological and anatomical data, we elaborate the novel hypothesis that the visual cortex controls the spatiotemporal structure of cortical receptive fields via feedback to the lateral geniculate nucleus. Furthermore, we present and analyze a model of corticogeniculate loops that implements this control, and exhibit its ability of object segmentation by statistical motion analysis in the visual field.

 Larva and puparium: Anterior fold with a wide spicule band. Anterior spiracles present, more than ten openings arranged in a crescent at the fan-like apex and the whole structure longer than surrounding spicules. Crochets of metathoracic prolegs forming a U-shaped band. Thoracic vestiture comprising fine setae, flattened against the integument. Anterodorsal and lateral margins of mesothorax and metathorax with spicules. Anteroventral margin of metathorax with a paired group of numerous spicules of varying sizes becoming shorter posteriorly. Abdominal vestiture comprising short and long setae, long setae confined to middle transverse folds on each segment. Vestiture between prolegs and on final section of anal segment, very short and inconspicuous. Abdominal prolegs with three, transverse rows of black crochets. Sensilla 9–11 on the ventral surface of the anal segment on short fleshy projections. Posterior breathing tube with TR deep and conspicuous. AP dark brown, faintly coriaceous, not strongly shining and 0.7¥ length of TR. Pupal spiracles long and spiracles almost reaching base, about 2.6¥ longer than AP.
 Taxonomic notes: The early stages of C. bequaerti are very distinctive because of the large anterior spiracles with 10+ openings, spicules on the anterodorsal margin of the metathorax, long and short abdominal vestiture, and pupal spiracles with openings almost reaching the base. No other species considered here has such a combination of characters. On adult features such as the brush-like form of the arista, C. bequaerti is part of the Marginatum group. On larval characters C. bequaerti is similar to the Satur group species in size, presence of anterior spiracles and sensilla 9–11 of the anal segment on short, fleshy projections.

description: The use of nanoparticles has grown tremendously in the past 25 years in virtually all ndustries from alternative energy formulations to drug delivery development and from semiconductor fabrication to cosmetic research. The main goal of this thesis is to shed light on the surface behavior of these universally used components. The thesis explores controlling surface reactivity of nanoparticles to great detail and concludes with a proven method to organize the nanoparticles using self-assembly. The consistent and reproducible organization of the nanoparticles has tremendous value in all industries using nanoparticles in lowering production and processing costs and time.The surface reactivity of the nanoparticles is found to be well-controlled. In Chapter 3, we show a method to control alkyne reactivity on nanoparticles using a mixture of organosilane monolayers. These surfaces have the unique ability to react with azide-terminated materials through the well-known copper catalyzed azide alkyne cycloaddition `click' reaction. We also put to use a new method to ensure that the mixed surface formed is reactively homogeneous; this novel technique will sure help research endeavors as this has not been demonstrated on surfaces of nanoparticles before. We extend our surface reactivity studies with the azide-functional surface in Chapter 4. Since we were unable to create a homogeneous surface using the methods described in Chapter 3, we looked to creating a mixed monolayer by kinetic control. This involved fabrication of a bromine-terminated surface and subsequent incomplete substitution of the bromide to azide. This method of creating mixed monolayers was shown to be universally applicable to surfaces of different chemical nature and different surface geometries with the same reaction kinetics. We also contend that this method of creating mixed monolayers is novel and it provides for an additional in the control of other surface reactivity groups. Chapter 5 provides the grand finale of the thesis with the intended use of the mixed monolayers surfaces to organize nanoparticles. We show that by carefully controlling the amount of polymer chemisorbed onto a surface, the self-assembly behavior of the particles is changed. In such a method we constructed a phase diagram showing how polymeric coverage controls selfassembly. We also ensured that the phases formed were indeed equilibrated structures by studying the formation of the phases under different preparation conditions. We encountered sheets, rods, and agglomerates and were able to consistently create these structures as well as study them using image analysis.
Environment from cross-correlations: connecting hot gas and the quenching of galaxies

description: The observable properties of galaxies depend on both internal processes and the external environment. In terms of the environmental role, we still do not have a clear picture of the processes driving the transformation of galaxies. The use of proxies for environment (e.g., host halo mass, distance to the N^th nearest neighbour, etc.), as opposed to the real physical conditions (e.g., hot gas density) may bear some responsibility for this. Here we propose a new method that directly links galaxies to their local environments, by using spatial cross-correlations of galaxy catalogues with maps from large-scale structure surveys (e.g., thermal Sunyaev-Zel'dovich [tSZ] effect, diffuse X-ray emission, weak lensing of galaxies or the CMB). We focus here on the quenching of galaxies and its link to local hot gas properties. Maps of galaxy overdensity and quenched fraction excess are constructed from volume-limited SDSS catalogs, which are cross-correlated with tSZ effect and X-ray maps from Planck and ROSAT, respectively. Strong signals out to Mpc scales are detected for most cross-correlations and are compared to predictions from the EAGLE and BAHAMAS cosmological hydrodynamical simulations. The simulations successfully reproduce many, but not all, of the observed power spectra, with an indication that environmental quenching may be too efficient in the simulations. We demonstrate that the cross-correlations are sensitive to both the internal (e.g., AGN and stellar feedback) and external processes (e.g., ram pressure stripping, harassment, strangulation, etc.) responsible for quenching. The methods outlined in this paper can be adapted to other observables and, with upcoming surveys, will provide a stringent test of physical models for environmental transformation.

Subjects: subject: Realistic Accuracy Model (RAM)
subject: Personality ratings
subject: Psychology
subject: FOS: Psychology

description: The aim of this thesis was to investigate the processes involved in constructing a personality rating: specifically, what judges attend to and use when rating personality. In doing so, this thesis addressed the call for research on factors that contribute to personality ratings, which was originally posed by Webb (1915). A key model for addressing this question and which is consequently integrated throughout this research is Funder’s (1995) realistic accuracy model (RAM). According to RAM, the accuracy of personality judgements is affected by the relevance, availability, detection, and utilisation of information. Based on RAM, Funder (1999) identified key factors that influenced personality judgements that were associated with the target of personality ratings, the personality trait, the quality and quantity of information, and the judge of personality ratings. These factors were used as a starting point to ascertain the types of information judges are most likely to attend to and use in rating personality.

description: We quantize a compactified version of the trigonometric Ruijse\-naars-Schneider particle model with a phase space that is symplectomorphic to the complex projective space CP^N. The quantum Hamiltonian is realized as a discrete difference operator acting in a finite-dimensional Hilbert space of complex functions with support in a finite uniform lattice over a convex polytope (viz., a restricted Weyl alcove with walls having a thickness proportional to the coupling parameter). We solve the corresponding finite-dimensional (bispectral) eigenvalue problem in terms of discretized Macdonald polynomials with q (and t) on the unit circle. The normalization of the wave functions is determined using a terminating version of a recent summation formula due to Aomoto, Ito and Macdonald. The resulting eigenfunction transform determines a discrete Fourier-type involution in the Hilbert space of lattice functions. This is in correspondence with Ruijsenaars' observation that---at the classical level---the action-angle transformation defines an (anti)symplectic involution of CP^N. From the perspective of algebraic combinatorics, our results give rise to a novel system of bilinear summation identities for the Macdonald symmetric functions.
Disability Among Women Workers and the Role of Social Support Systems

Subjects: Social service

description: The study examined factors affecting return to work following a short-term disability and measured the relationship between social support and the subject's well-being status, emphasizing the role of the social support system.

Subjects are 185 female city workers, members of District Council 37, AFSCME, AFL-CIO, and recently either physically or mentally disabled. They are entitled to a maximum of six-months short-term disability benefits.

Data, collected through a structured telephone interview, included the Arizona Social Support Interview Schedule (ASSIS), modified to the type of event (short-term disability), population (female), to measure perceived social support, and the General Well-Being Schedule to measure subjects' well-being. Univariate and multivariate statistical techniques were utilized.

Six variables predicted length of unemployment: (1) severity of illness; (2) general well-being; (3) type of disability (physical or mental); (4) quality of support from immediate family; (5) job tenure; and (6) perceived financial stress. None of the work social support variables were statistically significant in predicting length of unemployment.

A relationship between social support and well-being was found. Four variables predicted the subject's well-being status: (1) perceived financial stress; (2) job satisfaction; (3) quality of support from family; and (4) quality of support from friends.

Mentally disabled subjects remained longer on short-term disability than the physically disabled and a higher percentage were unemployed at the end of the six-month short-term disability, implying that they are at a greater risk of leaving the labor force.

Findings are consistent with existing research on the role of social support in promoting well-being and return to work, as well as identification of critical risk factors for leaving the labor force. These have critical implications for social work practice and policy, in general, and in union settings.

description: Hyptis pectinata is a herb popularly used in Brazil for the treatment of inflammations, pain, bacterial infections and cancer. In the present study, inflorescences (MPIn), leaves (MPL), branches (MPB), root (MPR) extracts and three compounds isolated from MPIn were assayed against breast tumor cell lines. The structures of the three compounds (pectinolide J, hyptolide and pectinolide E) were determined by means of spectroscopic analysis. Pectinolide J was isolated for the first time. The MPIn, MPL and MPR exhibited specific antiproliferative activity on tumor cell lines when compared to normal cell lines with IC50 of 52.01 ± 0.64, 45.91 ± 0.02 μg/mL and 82.84 ± 0.03 μg/mL, respectively. Although the isolated substances did not present good antiproliferative activity, when the three were associated, a greater biological effect was observed, suggesting a synergistic effect. Hyptolide (5.6 ± 0.4 μg/mL) showed IC50 sufficiently low to be considered as a drug prototype.

description: I classify the Finsler structures on the 2-sphere that have constant Finsler-Gauss curvature and whose geodesics are the great circles. Modulo diffeomorphism, there is a 2-parameter family of such Finsler structures, only one of which is homogeneous or symmetric, namely the Riemannian one. I discuss the history of the problem and its relation with Hilbert's Fourth Problem and the calculus of variations.

description: Im Rahmen einer Zusammenarbeit zwischen der Thüringer Landesanstalt für Umwelt und Geologie (TLUG) und der Goethe-Universität Frankfurt (GUF) fand in Kooperation mit dem Deutschen Wetterdienst (DWD) eine umfassende Studie zum konvektiven Unwetterpotential über Thüringen statt. Unwetterereignisse, die durch konvektive Prozesse in der Atmosphäre verursacht werden, besitzen ein nicht unerhebliches Schadenspotential, obwohl sie oftmals eine räumlich eng begrenzte Ausdehnung aufweisen. Aufgrund ihrer Charakteristik ist sowohl die Vorhersage solcher Ereignisse, als auch eine vollständige, systematische Erfassung für eine detaillierte Auswertung längerer Zeitreihen noch immer eine Herausforderung. Zusätzliches Interesse besteht in der Abschätzung der durch den Klimawandel abhängigen Entwicklung des zukünftigen Gefährdungspotentials konvektiver Unwetter. Für eine gezielte Untersuchung des Themenkomplexes ist eine Vielzahl unterschiedlicher Daten und Methoden verwendet worden. Mit Hilfe von Fernerkundungsdatensätzen wird ein räumlich differenziertes Gefährdungspotential über Thüringen nachgewiesen. Bedingt durch das Relief ist das Auftreten von Konvektion am häufigsten und intensivsten über dem südlichen Thüringer Wald und dessen Ostrand zu beobachten, während Nordthüringen eine deutlich geringere Aktivität solcher Unwetterereignisse aufweist. Eine Abschätzung mittels globaler Klimamodelle und daraus abgeleiteten Wetterlagen zeigt unter Berücksichtigung des RCP8.5 Klimaszenarios für die nahe Zukunft (2016-2045) eine Zunahme des Gefährdungspotentials durch konvektive Unwetter. Aufgrund des Anstiegs feuchter Wetterlagen (49 % auf 82 %) erhöht sich die Zunahme der Gefährdung für den Zeitraum 2071-2100 noch deutlicher. Im Vergleich zu diesem statistischen Ansatz nimmt die projizierte Gefährdung durch extreme Ereignisse erheblich zu (Faktor 6), wenn die Ergebnisse expliziter Simulationen konvektiver Ereignisse mit einem regionalen Klimamodell (mit horizontaler Gitterdistanz von 1 km) und eine Zunahme der Tage mit konvektiven Extremereignissen berücksichtigt werden. Ein Anstieg der Gefährdung durch konvektive Unwetter in der Zukunft ist wahrscheinlich. Eine Quantifizierung bleibt jedoch unsicher.

description: Polychlorinated biphenyls (PCBs), a group of persistent organic pollutants, are ubiquitous in the environment. The concentrations of PCBs and their metabolites are crucial to understand their impact on the environment. Here, a simultaneous method is reported to determine PCB101 and its hydroxylated, methoxylated and methyl sulfonated metabolites in aquatic organisms by gas chromatography–microelectron capture detection (GC-μECD). Several operational parameters, including the extraction solvent, volume of concentrated sulfuric acid for lipid removal, elution procedure, and solid-phase extraction (SPE) eluent volume, were optimized for the analytes in the muscle tissue of carp (Carassius auratus). Under the optimum conditions, the linearity of the method was from 2.5 to 100 ng/mL with correlation coefficients (R2) > 0.9961. The limit of detection was 2.00 μg/kg, and the limit of quantitation was equal to 5.00 μg/kg. The spiked recoveries of the targets in carp muscles were from 84.4% to 104%, and the relative standard deviation (RSD) was from 4.02% to 8.75%. The developed method was successfully applied to different aquatic samples. The precursor and metabolites were simultaneously detected in aquatic products. The metabolites of PCBs were present in marine samples collected from the East China Sea. For the first time, the methoxylated metabolite of PCB101 was identified in aquatic organisms. The results provide support for further study on the environmental properties and biological transmission of PCBs.

description: An analysis is made of reality conditions within the context of noncommutative geometry. We show that if a covariant derivative satisfies a given left Leibniz rule then a right Leibniz rule is equivalent to the reality condition. We show also that the matrix which determines the reality condition must satisfy the Yang-Baxter condition if the extension of the covariant derivative to tensor products is to satisfy the reality condition. This is equivalent to the braid condition for the matrix which determines the right Leibniz rule.

description: The global manufacturing sector is confronted with mounting challenges related to safety hazards and environmental sustainability. In response, there has been a growing emphasis on adopting circular economy principles as a transformative approach to address these pressing issues. This review explores the implementation of circular economy principles within manufacturing processes to enhance safety and environmental sustainability. Circular economy principles prioritize resource efficiency, waste reduction, and the continual use of materials within closed loops. By shifting from the traditional linear "take-makedispose" model to a circular approach, manufacturing facilities can significantly mitigate safety risks associated with hazardous waste generation and disposal. Moreover, the adoption of circularity fosters a culture of preventive measures, reducing the likelihood of workplace accidents and improving overall safety standards. Furthermore, integrating circular economy principles into manufacturing operations contributes to environmental sustainability by minimizing resource depletion and pollution. Through strategies such as product redesign for recyclability, remanufacturing, and waste valorization, manufacturers can reduce their reliance on virgin materials and curb emissions. This transition towards circularity not only diminishes the environmental footprint of manufacturing activities but also creates opportunities for cost savings and innovation. However, the successful implementation of circular economy principles in manufacturing requires a concerted effort from stakeholders across the value chain. Collaboration among manufacturers, suppliers, policymakers, and consumers is essential to overcome barriers such as technological limitations, regulatory constraints, and behavioral change resistance. Embracing circular economy principles holds immense potential for enhancing safety and environmental sustainability in manufacturing. Through systematic integration and collaboration, the manufacturing sector can pave the way towards a safer, more sustainable future

description: In Dhaka, the bus transportation system deals with the issues of insecurity, lack of dependability, inefficiency, and challenges in managing the daily mobility needs of its substantial populace. As a result, it becomes imperative to assess the effectiveness of bus service quality (SQ) through the lens of customer experiences. Despite numerous studies delving into the performance of public transportation systems in Bangladesh, there has been limited focus on comprehending how service quality attributes intersect with passenger satisfaction. In this context, this paper undertakes a comparative examination of user perceptions surrounding two recently launched public transport services in Dhaka city. To unravel the relationship of key indicators, a discrete choice model has been used. Constructed from a comprehensive survey of 1140 questionnaires, which assessed passengers' travel experiences and feedback, the choice model serves as the analytical framework. The outcomes of the model analysis sort out the SQ of both Bus Service-1 (BS-1) and Bus Service-2 (BS-2). Particularly, the assessment indicates that BS-1 accumulates an overall rating of "good," while BS-2 attains a "satisfactory" rating, based on a spectrum of preference levels encompassing "excellent," "satisfactory," "good," and "poor." Pertaining to attributes of service, such as travel time, BS-1 receives a positive rating with a coefficient of 0.413, whereas BS-2's rating stands at 0.168. The analysis also accentuates waiting time and mode availability as pivotal contributors to passenger satisfaction. The study's conclusions offer transportation planners a valuable opportunity to formulate strategic transport policies and regulations aimed at elevating service quality to meet specific goals
