description: The rapid expansion of information and communication technology (ICT) has accelerated the distribution of work across geographically dispersed areas, and this transnational relocation of work is viewed as a seamless transaction by proponents of technological globalization. However, a close examination of the collaboration involved in Indian/Japanese software offshoring illuminates an array of difficulties that problematize the "seamlessness" of this endeavor. This dissertation investigated the complex social world of offshoring by focusing on analyzing India-Japan software offshoring, and the study revealed corporate control as well as workers' efforts and struggles to make this ICT-supported relocation of work function smoothly. Through the analysis of the interviews with Indian software engineers and liaison officers between companies and within companies, in combination with observations of their workplaces, this dissertation highlights the corporate demands for flexibility in two layers: demands for being flexible in macro-labor circulations, to function as "labor buffers," and being flexible in terms of micro-communication issues and clients' demands. At the same time, it also reveals that corporate control is not a monolithic and totalizing force, but a complex and contradictory process generated through the struggles and intense labor of both Indian and Japanese sides that attempt to connect the disjunctions and make the business look "seamless." This study illuminates the irony that the relocation of work can intensify labor for both sides because of clients' micromanagement and communication difficulties. In addition, it also captures workers' efforts to distance themselves from corporate control, and their attempt to utilize the "onsite opportunity" to pursue their own interest. By highlighting the corporate demands for dual flexibility, as well as layers of communication difficulties and contradictions in Japan-Indian offshoring businesses, this dissertation provides insight into an anthropological and sociological analysis of offshoring as a complex global social phenomenon.

 Material examined. 1 ♂, with van Lennep label ‘ No. 15. POLIDORUS. Cr. II. 128. A. B.’ (BMNH (E)#665050) is correctly named but is not the same as the misidentified figures, which show hindwings with tails. Other markings, particularly the creamy discal spots on the hindwing differ considerably in arrangement. However, Cramer does mention a variety with little or no tail, and this specimen may relate to that; it has thoracic damage although the pin may be the original; there are some minor repairs to the wings, including suggestions that at one time tails were stuck to the hindwings and subsequently removed. It is intriguing that van Lennep was apparently able to correctly name this specimen, because this would hardly have been possible from reference to Cramer’s work (the only reference ever cited on van Lennep labels). It suggests that the specimen might have been associated with an earlier name label.
 Identity of figure. Pachliopta aristolochiae (Fabricius, 1793).
 Identity of specimen. Pachliopta p. polydorus (Linnaeus, 1763).

title: Positive Lebenserfahrungen Einzelner während der Corona-Pandemie
Creators: name: Sziderits, Elisabeth
Year: 2024

description: Diese Masterarbeit beschäftigt sich mit den von einzelnen Individuen als positiv betrachteten Auswirkungen der Corona-Pandemie. Dabei werden objektive und subjektive Dimensionen von Krisen (Steg 2020, 429) einander gegenübergestellt. Diese Erhebungen und deren Auswertung erfolgen aufgrund des theoretischen Hintergrunds der „Lebenswelt“, wie sie von Schütz & Luckmann konzipiert wurde. Gemäß diesem Hintergrund wurden sowohl individuelle Lebensbereiche und die in diesen Lebensbereichen gegebenen Handlungsmöglichkeiten berücksichtigt als auch die Interdependenz von Subjekten beachtet. Parallel zur Recherche des diesbezüglichen Forschungsstandes wurden episodische Interviews durchgeführt (N = 8). Diese wurden gewählt, da nicht wie bei narrativen Interviews die gesamten Lebenszyklen der InterviewpartnerInnen für diese Arbeit interessierten. Dennoch sollte im Rahmen dieser explorativen Forschung den befragten Personen die Möglichkeit gegeben werden, individuelle Schwerpunkte zu setzen, ohne auf einen bestimmten Lebensbereich eingeschränkt zu sein. Die Auswertung der Interviews erfolgte aufgrund des explorativen ergebnisoffenen Zugangs mittels Grounded Theory nach Anselm Strauss unter Nutzung von Maxqda. Die während der Corona-Pandemie zwar eingeschränkte, nichtsdestotrotz aber vorhandene-Handlungsmöglichkeit und interpersonelle Unterstützung wirkten sich positiv auf die Bewältigung der Krise aus.
description: This master's thesis deals with the effects of the coronavirus pandemic that individuals consider to be positive. It compares objective and subjective dimensions of crises (Steg 2020, 429). These surveys and their evaluation are based on the theoretical background of the "Lebenswelt" as conceptualised by Schütz & Luckmann. In accordance with this background, both individual areas of life and the possibilities for action given in these areas of life were taken into account as well as the interdependence of subjects. Episodic interviews (N = 8) were carried out in parallel to researching the current state of research in this area. These were chosen because, unlike narrative interviews, the entire life cycles of the interviewees were not of interest for this work. Nevertheless, this exploratory research was intended to give the interviewees the opportunity to set individual focal points without being restricted to a specific area of life. The interviews were analysed on the basis of the explorative, open-ended approach using grounded theory according to Anselm Strauss by using Maxqda. Although limited during the coronavirus pandemic, the ability to act and the interpersonal support that was nonetheless available had a positive effect on coping with the crisis.

description: This dissertation employs an organizational approach to examine how reentry organizations seek to provide social value as public-private partnerships with the mission statement of aiding the reintegration of the formerly incarcerated. With the help of a case study of a reentry organization in Cleveland, Ohio, I examine the sociological significance of the discursive “brokerage metaphor” of reentry organizations as brokers of the social and cultural capital the formerly incarcerated require as catalysts for their reintegration back into society.
      Based on ethnographic data and in-depth field interviews collected over a period of 16 months in Cleveland, Ohio, my research finds that the “brokerage metaphor” for reentry elides important factors which play an integral role in the organizational behavior of reentry organizations and the sociological experience of reentry for the formerly incarcerated. These other factors notably include the competitive and regulatory organizational environment of the reentry organization, and the intersectional identities of formerly incarcerated women. These external factors reveal the paradox of the public-private partnership represented by the reentry organization wherein some obstacles that stymie the objectives of the reentry organization might be attributed to its public partner, the government. Furthermore, my research finds that besides the brokerage of social and cultural capital, reentry organizations as public-private partnerships provide other tangible benefits for achieving the reentry of the formerly incarcerated, such as a remove from the carceral continuum that invites participation and creates the space for community-building.
      This dissertation research advances a new direction for the study of public-private partnerships wherein the lens of inquiry is not merely on the private partner, rather, the spotlight is also trained on the external impediments that prevent the organization from achieving full social value. This direction for research bodes well for determining appropriate and effective ethical policy interventions to addressing pressing social problems through public-private partnerships and social enterprise.

description: Based on a true phase space probability distribution function and an ensemble averaging procedure we have recently developed [Phys. Rev. E 65, 021109 (2002)] a non-Markovian quantum Kramers' equation to derive the quantum rate coefficient for barrier crossing due to thermal activation and tunneling in the intermediate to strong friction regime. We complement and extend this approach to weak friction regime to derive quantum Kramers' equation in energy space and the rate of decay from a metastable well. The theory is valid for arbitrary temperature and noise correlation. We show that depending on the nature of the potential there may be a net reduction of the total quantum rate below its corresponding classical value which is in conformity with earlier observation. The method is independent of path integral approaches and takes care of quantum effects to all orders.

description: Given a $7$-dimensional compact Riemannian manifold $\left( M,g\right) $ that admits $G_{2}$-structure, all the $G_{2}$-structures that are compatible with the metric $g$ are parametrized by unit sections of an octonion bundle over $M$. We define a natural energy functional on unit octonion sections and consider its associated heat flow. The critical points of this functional and flow precisely correspond to $G_{2}$-structures with divergence-free torsion. In this paper, we first derive estimates for derivatives of $V\left( t\right) $ along the flow and prove that the flow exists as long as the torsion remains bounded. We also prove a monotonicity formula and and an $\varepsilon $-regularity result for this flow. Finally, we show that within a metric class of $G_{2}$-structures that contains a torsion-free $G_{2}$-structure, under certain conditions, the flow will converge to a torsion-free $G_{2}$-structure.

Bronzino, Politics and Portraiture in 1530s Florence

description: This dissertation examines paintings by the Florentine artist Agnolo Bronzino, and by his teacher, Jacopo Pontormo.  It takes as its focus works created during the period of 1529-39, a decade of political uncertainty and social unrest predating Bronzino's career as court painter.  The study begins during the brutal Siege of Florence in 1529-30, which brought an end to the last Florentine republic.  Although the republic's defeat made way for the establishment of the Medici duchy, the 1530s were marked by fervent and unrelenting republican opposition to the new dukes.  These circumstances provide the background to this study, in which paintings by Bronzino and Pontormo are shown to offer eloquent--if sometimes cautious--comment on recent political events.
       The initial chapters address the relationship between two paintings carried out during the Siege, reconciling Pontormo's Portrait of a Halberdier (Francesco Guardi) with its allegorical cover, Bronzino's Pygmalion and Galatea.  The first chapter reconsiders the role of Venus in Bronzino's painting, attributing to her a rousing, rather than pacifying, influence; she is shown to be a deity especially well-suited for reverence by young Florentine soldiers, and a fitting subject for the cover of Pontormo's republican portrait.  The second chapter explores the specific political significance of Bronzino's artistic choices, paying special attention to his allusion to Michelangelo's marble David, whose form he incorporates into the figure of Pygmalion's beloved Galatea.
       The young hero David--shown to be one of the period's most potent republican symbols--is somehow manifest in each of the paintings considered, linking the four chapters.  But whereas the Pygmalion and Galatea and Portrait of a Halberdier are explained as republican pictures created under republican rule, the portraits examined in the third and fourth chapters are presented as subversive images created under the Medici dukes.  The third chapter reinterprets Bronzino's Portrait of Ugolino Martelli (c. 1537), as an expression of republican opposition to ducal rule.  The fourth chapter proposes a new dating for Pontormo's Portrait of Carlo Neroni--presently understood as a republican picture dating to the period of the Siege--relocating its origin to c. 1538-9, well after the republic's defeat.  This reassessment has important implications for a number of portraits by both artists, and it calls into question currently accepted art-historical approaches to Florentine culture in the 1530s.  By identifying examples of republican factionalism in portraits painted by Pontormo and Bronzino under Medici rule, this dissertation discovers political dissent where previously considered impossible.
Brown Vs. Brownsville Why Today’s Black Activists Are Challenging The School Desegregation Paradigm

description: The U.S. Civil Rights Movement of the 1950s and early 1960s is synonymous with the struggle for desegregation in every aspect of society, perhaps most famously within the nation’s public schools. As embodied in the Supreme Court’s historic ruling in Brown v. Board of Education of Topeka, Kansas, racially integrated schools were deemed to be an essential component of equal opportunity in education. By the mid-to-late-1960s, however, the consensus around school desegregation had splintered. While the mainstream civil rights organizations stood by their integrationist creed, a rising Black Power movement challenged the old-line leadership and insisted that community control and selfdetermination were the only path for the liberation of black people. These separatists rejected integrated public schools as instruments of white supremacy. Their proposed alternative was to have schools run by black communities specifically for the benefit of black students. In 1968, this was the animating principle behind the push for community control in Brownsville, Brooklyn, which triggered a notorious, citywide teachers’ strike. More than six decades after Brown, U.S. public schools in general have resegregated to the point where there is less integration than in the late 1960s. A new generation of black-led activist organizations, affiliated with the Movement for Black Lives, has all but abandoned the hope or desire for school desegregation. In a reprise of the calls to Black Power, these groups believe that the path to educational equality lies in autonomous public schools controlled by local black communities and run by black administrators and a predominantly black teaching staff. In a rebuke to Brown, they assert that only separate can possibly become equal. The text explains this attitudinal shift through interviews with leaders of the Movement for Black Lives, along with an archival examination of the historical positions on toward school desegregation by both the Civil Rights Movement and Black Power advocates. It addresses its central question through the lens of Critical Race Theory, which reveals the contradiction within liberal approaches to the enduring issue of racial inequality in U.S. schools, and also a fundamental disagreement over the goals of public education.
Bubble Rise Dynamics in Complex Fluids

description: Formation of gas bubbles in complex fluids and their subsequent rise due to buoyancy is a very important fundamental phenomenon both in nature and industry. Bubble size and bubble velocity are critical parameters which govern the interfacial transport phenomena and play an important role in gas-solid contact. These characteristics affect the operating parameters as well as the design of equipment in industrial applications. Non-Newtonian, Shear-thickening fluids have been studied extensively due to their immense potential for commercial use in shock absorbing and force damping applications, such as liquid body armor, sports and personal protection. Furthermore, a better understanding of shear-thickening fluid is pertinent to industrial processing for enhancing flow, preventing the breakage or clogging of mixing equipment, and preventing clogging in narrow orifices. Despite their significance, many aspects of the flow of these non-Newtonian fluids remain poorly understood. In the first part of this dissertation, we study the dynamics of rising bubbles in three dimensional fluidized beds using computational fluid dynamics-discrete element method (CFD-DEM) to shed light on the physics underpinning phenomena uncovered previously using magnetic resonance imaging (MRI). We were able to understand the underlying mechanism behind the anomalous collapse of a bubble in side-by-side injection as well as an alternating asynchronous pinch-off pattern due to jet interaction in a fluidized bed by looking into the gas streamlines and the drag force on the particles. In the second part of this dissertation, we study dynamics of rising bubbles in Newtonian fluids and non-Newtonian cornstarch-water suspensions experimentally using optical imaging. We were able to identify that Capillary number (Ca) is a key dimensionless parameter governing the regimes of interacting jets in water. We also observed a periodic coalescence of bubbles at the same points in space in cornstarch-water suspensions and attributed this behavior to leading bubbles entering a shear thickening regime. Further, we identified the key dimensionless parameters for wobbling behavior of single bubbles in cornstarch suspensions to be Bond (Bo), and Reynolds (Re) number, regardless of the bubble being in a Newtonian or a shear-thinning regime. We believe our findings can be applied in industry to optimize the mass transport and liquid mixing for a range of applications.

description: Due to its very low viscosity, cryogenic helium has been used for years to generate high Reynolds turbulent flows. The measurement of velocity fluctuations in such high Reynolds flows is however a challenging issue, as it is necessary to develop small size (typically micron-length), robust sensors, to measure the whole spectrum of fluctuations of the velocity, which may extend to hundreds of kHz and possibly higher. SBT has developed for years different facilities, in particular taking benefit of the refrigeration capacities available at CEA Grenoble. In this article we present the current status of developments of hot wire sensors at CEA. Different characterizations of Wollaston hot wires are shown, and measurements of velocity fluctuations in different conditions, in normal helium as well as in superfluid helium are shown.

description: Massive cities in China are experiencing a shift in their economic structure from traditional manufacturing to service and skill-intensive manufacturing, which leaves behind underused or abandoned industrial sites with real or perceived contamination problems in central cities and/or peripheral regions. A comprehensive and sustainable strategy for brownfield remediation and redevelopment, which embraces ecological, economic and social benefits, is a hot topic in China. However, the country is lacking a comprehensive and effective legal and regulatory framework for brownfield remediation and redevelopment, uniform national standards on site assessment, cleanup and remediation, and effective funding or financing mechanisms from the national level to local levels. The purpose of this study is to examine policy tools that are being adopted in China to deal with brownfield remediation and redevelopment, compare them to those employed in the United States, make recommendations to improve existing frameworks, and try to coordinate cross-purpose programs in an integrated legal and regulatory framework.

description: If $p : Y \to X$ is an unramified covering map between two compact oriented surfaces of genus at least two, then it is proved that the embedding map, corresponding to $p$, from the Teichmüller space ${\cal T}(X)$, for $X$, to ${\cal T}(Y)$ actually extends to an embedding between the Thurston compactification of the two Teichmüller spaces. Using this result, an inductive limit of Thurston compactified Teichmüller spaces has been constructed, where the index for the inductive limit runs over all possible finite unramified coverings of a fixed compact oriented surface of genus at least two. This inductive limit contains the inductive limit of Teichmüller spaces, constructed in \cite{BNS}, as a subset. The universal commensurability modular group, which was constructed in \cite{BNS}, has a natural action on the inductive limit of Teichmüller spaces. It is proved here that this action of the universal commensurability modular group extends continuously to the inductive limit of Thurston compactified Teichmüller spaces.

description: Learning through a variety of online platforms, including Learning Management Systems (LMS) and functionalities within them, such as Discussion Boards, and Social Networking Sites (SNS), such as Facebook, is becoming an increasingly popular way of communicating with students and enhancing student learning (Caldwell, 2015). However, despite this increasing popularity amongst educators and students, there is limited research concerning SNS and LMS (i.e. Facebook and Discussion Boards) as functionalities for promoting effective learning and teaching in higher education. Therefore, this study has drawn upon the work of Bandura’s Self-efficacy model (1977) to critically examine academics’ and students’ perceptions of the perceived use, benefits and concerns of Facebook and Discussion Boards for learning and teaching. Following ethical clearance, data were collected using two surveys consisting of Likert-scale and open-ended questions investigating academic and student perceptions pertaining to Facebook and Discussion Board uses, benefits, concerns, frequency of use, General Self-efficacy, Facebook Self-efficacy and Discussion Board Self-efficacy. Surveys were administered to students and academic population consisting of a total of 339 participants (275 students; 64 academics), drawn from the Griffith Health Group, at Griffith University. The Griffith Health Group consists of eight schools, which are the School of Applied Psychology, School of Nursing and Midwifery, School of Allied Health Science, School of Medical Science, School of Medicine, School of Dentistry and Oral Health, and the School of Human Services and Social Work. Data were analysed using a mixed-methods approach, involving, where applicable, both correlational and thematic analysis.

description: To investigate whether growth hormone (GH) can improve oxidative stress (OS) by affecting) /nuclear factor erythroid 2-related factor 2 (Nrf2)/Kelch-like ECH-associated protein 1 (Keap1) in women of advanced age undergoing in vitro fertilization (IVF). This retrospective study enrolled 141 patients, including 65 aged C patients (patients not treated with GH) and 76 aged GH patients (patients treated with GH). The outcomes included IVF-ET results, OS markers in follicle fluid (FF) and Nrf2 and Keap1 mRNA and protein expressions in granulosa cells (GCs). The results showed that GH improved the available blastocyst (p=.047) and implantation rate (p=.043) in women of advanced age undergoing IVF. The malondialdehyde (MDA) content of FF was significantly higher in the aged-C group than in the aged-GH group (p=.013). The antioxidant enzyme activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-px) and catalase (CAT) were significantly lower in the aged-C group than in the aged-GH group (p= .000, p= .049, p= .012 respectively). Nrf2 mRNA and protein expression was significantly higher and Keap1 mRNA and protein expression was lower in the aged-GH group than in the aged-C group (p= .000, p= .000 respectively). The study showed that GH improved embryo quality and implantation rate and alleviated OS in FF, which may be related to Nrf2/Keap1.

description: From a kinematical point of view, the geometrical information of hamiltonian chaos is given by the (un)stable directions, while the dynamical information is given by the Lyapunov exponents. The finite time Lyapunov exponents are of particular importance in physics. The spatial variations of the finite time Lyapunov exponent and its associated (un)stable direction are related. Both of them are found to be determined by a new hamiltonian of same number of degrees of freedom as the original one. This new hamiltonian defines a flow field with characteristically chaotic trajectories. The direction and the magnitude of the phase flow field give the (un)stable direction and the finite time Lyapunov exponent of the original hamiltonian. Our analysis was based on a $1{1\over 2}$ degree of freedom hamiltonian system.

description: Semantic segmentation for lightweight object parsing is a very challenging task, because both accuracy and efficiency (e.g., execution speed, memory footprint or computational complexity) should all be taken into account. However, most previous works pay too much attention to one-sided perspective, either accuracy or speed, and ignore others, which poses a great limitation to actual demands of intelligent devices. To tackle this dilemma, we propose a novel lightweight architecture named Context-Integrated and Feature-Refined Network (CIFReNet). The core components of CIFReNet are the Long-skip Refinement Module (LRM) and the Multi-scale Context Integration Module (MCIM). The LRM is designed to ease the propagation of spatial information between low-level and high-level stages. Furthermore, channel attention mechanism is introduced into the process of long-skip learning to boost the quality of low-level feature refinement. Meanwhile, the MCIM consists of three cascaded Dense Semantic Pyramid (DSP) blocks with image-level features, which is presented to encode multiple context information and enlarge the field of view. Specifically, the proposed DSP block exploits a dense feature sampling strategy to enhance the information representations without significantly increasing the computation cost. Comprehensive experiments are conducted on three benchmark datasets for object parsing including Cityscapes, CamVid, and Helen. As indicated, the proposed method reaches a better trade-off between accuracy and efficiency compared with the other state-of-the-art methods.

description: Empirical potential structure refinement (EPSR) is a neutron scattering data analysis algorithm and a software package. It was developed by the British spallation neutron source (ISIS) Disordered Materials Group in 1980s, and aims to construct the most-probable atomic structures of disordered liquids. It has been extensively used during the past decades, and has generated reliable results. However, it is programmed in Fortran and implements a shared-memory architecture with OpenMP. With the extensive construction of supercomputer clusters and the widespread use of graphics processing unit (GPU) acceleration technology, it is now necessary to rebuild the EPSR with these techniques in the effort to improve its calculation speed. In this study, an open source framework NeuDATool is proposed. It is programmed in the object-oriented language C++, can be paralleled across nodes within a computer cluster, and supports GPU acceleration. The performance of NeuDATool has been tested with water and amorphous silica neutron scattering data. The test shows that the software could reconstruct the correct microstructure of the samples, and the calculation speed with GPU acceleration could increase by more than 400 times compared with CPU serial algorithm at a simulation box consists about 100 thousand atoms. NeuDATool provides another choice for scientists who are familiar with C++ programming and want to define specific models and algorithms for their analyses.

description: We consider the stationary spherical accretion process of perfect fluids onto a class of spherically symmetric regular black holes corresponding to quantum-corrected Schwarzschild spacetimes. We show that the accretion rates can differ from the Schwarzschild case, suggesting that the de Sitter core inside these regular black holes, which indeed precludes the central singularity, can act for some cases as a sort of antigravitational source, decreasing the fluid's radial infall velocity in the accretion process, and for others as a gravitational enhancer, increasing the fluid flow into the black hole horizon. Our analysis and results can be extended and also applied to the problem of black hole evaporation in cosmological scenarios with phantom fluids. In particular, we show that the mass of typical regular black holes can be used in order to constrain turnaround events in cyclic cosmologies.

description: The geometric dimensionality of a physical system significantly impacts its fundamental characteristics. While experiments are fundamentally limited to the maximum of three spatial dimensions, there is a growing interest in harnessing additional synthetic dimensions. In our work, we introduce a new paradigm for the experimental realization of excitation dynamics associated with many-dimensional systems. Crucially, it relies solely on static one-dimensional equivalent structures with judiciously tailored parameters to faithfully reproduce the same optical spectrum and density of states of the high-dimensional system to be represented. In order to showcase the capabilities of our approach, we fabricate 1D photonic lattices that exhibit the characteristic non-monotonic excitation decays associated with quantum walks in up to 7D square lattices. Furthermore, we find that a new type of bound state at the edge of the continuum emerges in higher-than-three dimensions and gives rise to a sharp localisation transition at defect sites. In a series of experiments, we implement the mapped equivalent lattices of up to 5D systems and observe an extreme increase of sensitivity with respect to the detuning of the respective anchor sites. Our findings demonstrate the feasibility and applicative potential of harnessing high-dimensional effects in planar photonics for ultra-sensitive switching or sensing. Notably, our general approach is by no means limited to optics, and can readily be adapted to a variety of other physical contexts, including cold atoms and superconducting qubits with exclusively nearest-neighbour interactions, promising to drive significant advances in different fields including quantum simulations and information processing.
