description: Der Beitrag fokussiert auf die Beziehung zwischen Vermarktlichung, der zunehmenden Subjektivierung von Arbeit und den Geschlechterverhältnissen am Arbeitsplatz. Er untersucht Möglichkeiten und Gelegenheiten, Solidarität in den Bereichen von Arbeit und Geschlechterpolitik auszudrücken, während der Begriff des Kapitals sich in alle Felder des sozialen Lebens ausdehnt. Die Autorin zieht dazu eine kürzlich abgeschlossene empirische Untersuchung bei der Deutsche Bahn AG heran. Zusammenfassend wird festgestellt, dass die Transformation von Arbeit ein hochdynamischer Prozess ist, der männliche und weibliche Beschäftigte betrifft, dass sich aber nur wenige Impulse für die betrieblichen Geschlechterverhältnisse zeigen.
Mean-field theory is exact for Ising spin glass models with Kac potential in non-additive limit on Nishimori line

description: Recently, Mori [Phys. Rev. E 84, 031128 (2011)] has conjectured that the free energy of Ising spin glass models with the Kac potential in the non-additive limit, such as the power-law potential in the non-additive regime, is exactly equal to that of the Sherrington-Kirkpatrick model in the thermodynamic limit. In this study, we prove that his conjecture is true on the Nishimori line at any temperature in any dimension. One of the key ingredients of the proof is the use of the Gibbs-Bogoliubov inequality on the Nishimori line. We also consider the case in which the probability distribution of the interaction is symmetric, where his conjecture is true at any temperature in one dimension but is an open problem in the low-temperature regime in two or more dimensions.

description: Tax disputes are inherent parts of a tax system, and require resolution mechanisms that effectively regulate and protect the interest of disputing parties. Commonly, countries provide for several layers of dispute resolution schemes. The schemes comprise internal review and external dispute resolution mechanisms that include quasi-judicial tax tribunals, courts and different kinds of Alternative Dispute Resolution methods. Ethiopia has made successive reforms on the laws and institutions pertaining to taxation and tax dispute resolution procedures. Despite successive reforms in the substantive content of tax laws, the dispute resolution system by and large remained the same. The 2016 reform, one of the latest reform moves, maintained much of the dispute resolution institutions with some changes in the details. The failure or success associated with these reforms and the overall application of tax dispute resolution system in the country has not been sufficiently studied. Using a qualitative research approach, this research thoroughly examined the Ethiopian law and the practice pertaining to the prevailing tax dispute resolutions system at Review Department of the Ministry of Revenue and the Federal Tax Appeal Commission. The research found out several legal and practical limitations regarding geographical accessibility, independence, legal certainty and access to justice. Thus, the existing tax dispute resolution system of Ethiopia needs to be re-visited so that the Country will have a tax dispute resolution system that balances the interest of the public and taxpayers.

description: Summation-by-parts (SBP) operators allow us to systematically develop energy-stable and high-order accurate numerical methods for time-dependent differential equations. Until recently, the main idea behind existing SBP operators was that polynomials can accurately approximate the solution, and SBP operators should thus be exact for them. However, polynomials do not provide the best approximation for some problems, with other approximation spaces being more appropriate. We recently addressed this issue and developed a theory for one-dimensional SBP operators based on general function spaces, coined function-space SBP (FSBP) operators. In this paper, we extend the theory of FSBP operators to multiple dimensions. We focus on their existence, connection to quadratures, construction, and mimetic properties. A more exhaustive numerical demonstration of multi-dimensional FSBP (MFSBP) operators and their application will be provided in future works. Similar to the one-dimensional case, we demonstrate that most of the established results for polynomial-based multi-dimensional SBP (MSBP) operators carry over to the more general class of MFSBP operators. Our findings imply that the concept of SBP operators can be applied to a significantly larger class of methods than is currently done. This can increase the accuracy of the numerical solutions and/or provide stability to the methods.

description: The paper presents new results on localisation and transmission of flexural waves in a structured plate containing a semi-infinite two-dimensional array of rigid pins. In particular, surface waves are identified and studied at the interface boundary between the homogeneous part of the flexural plate and the part occupied by rigid pins. A formal connection has been made with the dispersion properties of flexural Bloch waves in an infinite doubly periodic array of rigid pins. Special attention is given to regimes corresponding to standing waves of different types as well as Dirac-like points, that may occur on the dispersion surfaces. A single half-grating problem, hitherto unreported in the literature, is also shown to bring interesting solutions.

description: Ground pressure exerted by the human body is a valuable source of information for human activity recognition (HAR) in unobtrusive pervasive sensing. While data collection from pressure sensors to develop HAR solutions requires significant resources and effort, we present a novel end-to-end framework, PresSim, to synthesize sensor data from videos of human activities to reduce such effort significantly. PresSim adopts a 3-stage process: first, extract the 3D activity information from videos with computer vision architectures; then simulate the floor mesh deformation profiles based on the 3D activity information and gravity-included physics simulation; lastly, generate the simulated pressure sensor data with deep learning models. We explored two approaches for the 3D activity information: inverse kinematics with mesh re-targeting, and volumetric pose and shape estimation. We validated PresSim with an experimental setup with a monocular camera to provide input and a pressure-sensing fitness mat (80x28 spatial resolution) to provide the sensor ground truth, where nine participants performed a set of predefined yoga sequences.

Alterations in Foot Plantar Pressures and Contact Area with Plantar Electrical Stimulation
Creators: name: Gibson, Christopher Lee
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Hyperpronation is a risk factor associated with medial tibial stress syndrome, patellar femoral pain syndrome, and ACL injuries. Previous research with site-specific electrical stimulation to the plantar sole has shown significant alterations in activity of muscles associated with those sites. The purpose of this study was to examine the effects of sensory-level electrical stimulation to the medial longitudinal arch on foot contact pressure-time-integral (PTI) and contact area associated with hyperpronation during two barefoot conditions, one electrode pad only and one electrical stimulation condition. No significant differences were found between conditions for midfoot and rearfoot PTI. Midfoot contact area was greater for electrode pad only and electrical stimulation than both barefoot conditions, which is likely due to the thickness of the pads attached to the plantar surface touching down before the sole would without them. No significant difference was found between electrode pad only and electrical stimulation.

description: We discuss the procedure for obtaining measurement-based implementations of quantum algorithms given by quantum circuit diagrams and how to reduce the required resources needed for a given measurement-based computation. This forms the foundation for quantum computing on photonic systems in the near term. To demonstrate that these ideas are well grounded we present three different problems which are solved by employing a measurement-based implementation of the variational quantum eigensolver algorithm (MBVQE). We show that by utilising native measurement-based gates rather than standard gates, such as the standard CNOT, MBQCs may be obtained that are both shallow and have simple connectivity while simultaneously exhibiting a large expressibility. We conclude that MBVQE has promising prospects for resource states that are not far from what is already available today.

description: Superconductivity and ferromagnetism are antagonistic forms of order, and rarely coexist. Many interesting new phenomena occur, however, in hybrid superconducting/ferromagnetic systems. For example, a Josephson junction containing a ferromagnetic material can exhibit an intrinsic phase shift of pi in its ground state for certain thicknesses of the material. Such "pi-junctions" were first realized experimentally in 2001, and have been proposed as circuit elements for both high-speed classical superconducting computing and for quantum computing. Here we demonstrate experimentally that the phase state of a Josephson junction containing two ferromagnetic layers can be toggled between 0 and pi by changing the relative orientation of the two magnetizations. These controllable 0-pi junctions have immediate applications in cryogenic memory where they serve as a necessary component to an ultra-low power superconducting computer. Such a fully superconducting computer is estimated to be orders of magnitude more energy-efficient than current semiconductor-based supercomputers. Phase controllable junctions also open up new possibilities for superconducting circuit elements such as superconducting "programmable logic," where they could function in superconducting analogs to field-programmable gate arrays.

description: Due to increased complexity, scale, and functionality of information and telecommunication (IT) infrastructures, everyday new exploits and vulnerabilities are discovered. These vulnerabilities are most of the time used by malicious people to penetrate these IT infrastructures for mainly disruptingbusiness or stealing intellectual properties. Current incidents prove that it is not sufficient anymore to perform manual securitytests of the IT infrastructure based on sporadic securityaudits. Instead networks should be continuously testedagainst possible attacks. In this paper we present current resultsand challenges towards realizing automated and scalablesolutions to identify possible attack scenarios in an IT infrastructure. Namely, we define an extensible framework whichuses public vulnerability databases to identify probable multistepattacks in an IT infrastructure, and provide recommendations in the form of patching strategies, topology changes, and configuration updates.

We find tight upper and lower bounds for the worst case error of optimal algorithms that use $n$ function values. More specifically, we study integrals of the form \[ I_k^ρ(f) = \int_{ {\mathbb{R}}} f(x) \,e^{-i\,kx} ρ(x) \, {\rm d} x\ \ \ \mbox{for}\ \ f\in H^s({\mathbb{R}})\ \ \mbox{or}\ \ f\in C^s({\mathbb{R}}) \] with $k\in {\mathbb{R}}$ and a smooth density function $ρ$ such as $ ρ(x) = \frac{1}{\sqrt{2 π}} \exp( -x^2/2) $. The optimal error bounds are $Θ((n+\max(1,|k|))^{-s})$ with the factors in the $Θ$ notation dependent only on $s$ and $ρ$.

description: We review results from our monitoring observations of several lensed quasars performed in the optical, UV, and X-ray bands. Modeling of the multi-wavelength light curves provides constraints on the extent of the optical, UV, and X-ray emission regions. One of the important results of our analysis is that the optical sizes as inferred from the microlensing analysis are significantly larger than those predicted by the theoretical-thin-disk estimate. In a few cases we also constrain the slope of the size-wavelength relation. Our size constraints of the soft and hard X-ray emission regions of quasars indicate that in some objects of our sample the hard X-ray emission region is more compact than the soft and in others the soft emission region is smaller. This difference may be the result of the relative strengths of the disk-reflected (harder and extended) versus corona-direct (softer and compact) components in the quasars of our sample. Finally, we present the analysis of several strong microlensing events where we detect an evolution of the relativistic Fe line profile as the magnification caustic traverses the accretion disk. These caustic crossings are used to provide constraints on the innermost stable circular orbit (ISCO) radius and the accretion disk inclination angle of the black hole in quasar RX J1131-1231.

An Epidemiological Transition in the Chinese Northern Zone
Creators: name: Berger, Elizabeth Sarah
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Bioarchaeological research has greatly contributed to an understanding of the health consequences of the transition to agriculture in prehistory. This paper proposes that a similarly dramatic transition in health accompanied the transition to pastoralism during the Bronze Age in the Chinese Northern Zone. Bioarchaeological data, in combination with other types of data, can be used to test the hypothesis that the advent of pastoralism and agropastoralism in the Northern Zone was accompanied by a reduction in infectious diseases and dietary deficiencies, and an improvement in population health. This work can build on previous work in the region by moving beyond the consideration of human behavior change in its sociopolitical context, to consider it in its ecological context. It will consider humans as one element in complex, multi-scalar systems, and will examine the health consequences for humans when the cultural-natural systems of which they are a part undergo reorganization and transformation.

description: The equations for gravitational plane waves produced by a typical binary system as a solution of linear approximation of Einstein equations is derived. The dynamics of the corresponding gravitational field is analyzed in a 4-dimensional space-time manifold, endowed with a metric and taking into account the torsion. In this context, the geometrical reason of the existence of torsion due to the presence of gravitational waves, as an asymmetry of connection coefficients with respect of the swapping of indices's is highlighted. In a laser interferometer gravitational detector The delay time between the arrivals of the two laser beams traveling back and forth along the two arms of in presence of gravitational waves, is interpreted from this point of view. The geometrical interpretation of torsion, links this delay time to the breaking of the parallelogram formed by the trajectories of the laser beams in space-time. This delay is calculated for a typical NS-NS binary pulsar in two specific orientations with respect of the experimental device, corresponding to different polarizations of the gravitational waves. These values are related to the relative length variation of the detector's arms in presence of gravitational waves, and shown to be completely equivalent to the results obtained in the context of the standard General Relativity.

Teacher Retention and the Impact of North Carolina’s New Definition of a Low-performing School
Creators: name: Giles, Janice
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Teachers are a resource, and equitable resource allocation must include the equitable distribution of teachers across all schools. Previous research has found that high poverty and minority students are more likely to be taught by inexperienced and unqualified teachers, and teachers frequently leave schools serving these students for schools with fewer disadvantaged students (Boyd, Lankford, Loeb, & Wyckoff, 2005; Goldring, Taie, & Riddles, 2014; Hanushek, Kain, & Rivkin, 2004; Ingersoll, 2004; Loeb, Darling-Hammond, & Luczak, 2005). Further, previous research indicates that the challenges these schools face retaining effective teachers is due to poor working conditions, not teachers’ discontent with their students (Boyd et al., 2011; Johnson, Kraft, & Papay, 2012; Ladd, 2011). These findings establish a need to investigate how current polices may have contributed to the disparities in teacher retention rates. The purpose of this study was to examine the impact of North Carolina’s new definition of a low-performing school on teacher retention and teacher working conditions.
      This study used a quantitative causal-comparative design and analyzed secondary administrative data files from the North Carolina Department of Public Instruction as well as survey data from the North Carolina Teacher Working Conditions Survey. Data analysis was conducted using descriptive statistics and multiple regression analysis. The results showed that newly designated low-performing schools had lower average teacher retention rates and lower average North Carolina Teacher Working Conditions Survey results than other schools in the state. Multiple regression analysis found that the relationship between the state’s new definition of a low-performing school and teacher retention rates was not statistically significant, and the relationship between the state’s new definition of a low-performing school and teacher working condition survey results was statistically significant. Findings indicate that the state’s new definition a low-performing school negatively impacted teacher working conditions at newly designated low-performing schools and suggest that these schools will need to improve teacher working conditions in order to raise teacher retention rates to the state average.

description: ChaosNet is a type of artificial neural network framework developed for classification problems and is influenced by the chaotic property of the human brain. Each neuron of the ChaosNet architecture is the one-dimensional chaotic map called the Generalized Luroth Series (GLS). The addition of GLS as neurons in ChaosNet makes the computations straightforward while utilizing the advantageous elements of chaos. With substantially less data, ChaosNet has been demonstrated to do difficult classification problems on par with or better than traditional ANNs. In this paper, we use Chaosnet to perform a functional classification of Hypothetical proteins [HP], which is indeed a topic of great interest in bioinformatics. The results obtained with significantly lesser training data are compared with the standard machine learning techniques used in the literature.
title: Essays in international migration and migrants' remittances
Creators: name: Vadean, Florin-Petru
Publisher: name: University of Kent
Year: 2023

description: The essays included in this thesis aim to contribute to the better understanding of the international migration phenomenon and its impact on the migrant sending countries through the empirical investigation of four aspects: (1) the characteristics of circular migrants and the factors that influence their decision to move repeatedly; (2) the occupational attainment of return migrants and the impact on entrepreneurship; (3) the relationship between transfers and the general expenditures of the permanent migrant household; and (4) the role played by the migrant's education/skill level in the purpose and use of monetary remittances in the home country. Evidence from Albania shows that re-migration of return migrants (i.e. circularity) occurs along the same selection pattern as initial migration and return. From the initial low to middle educated migrant population those with the highest education return to Albania, and from the returnees those having less education are most likely to re-migrate. In fact, return migrants are found to contribute to employment generating activities, having comparatively the highest odds of being entrepreneurs. However, even if the migrants do not return to the home country and settle aboard permanently, they still can make a positive impact on the home economy over the money transfers to relatives or investments made in the home country. As shown by evidence from the Canadian immigration experience, some migrant groups regard transfers to relatives rather a normal good and, hence, would eventually share a more stable portion of their expenditures with the extended family in periods of economic downturn. Additionally, evidence from immigration to Germany illustrates that the human capital endowment is significantly linked to the decision to invest in the home country. Nevertheless, the economic and political climate in the country of origin seems to play an equally important role.

description: The equations of a planar elastica under pressure can be rewritten in a useful form by parametrising the variables in terms of the local orientation angle, $θ$, instead of the arc length. This ``$θ$-formulation'' lends itself to a particularly easy boundary layer analysis in the limit of weak bending stiffness. Within this parameterization, boundary layers are located at inflexion points, where $θ$ is extremum, and they connect regions of low and large curvature. A simple composite solution is derived without resorting to elliptic functions and integrals. This approximation can be used as an elementary building block to describe complex shapes. Applying this theory to the study of an elastic ring under uniform pressure and subject to a set of point forces, we discover a snapping instability. This instability is confirmed by numerical simulations. Finally, we carry out experiments and find good agreement of the theory with the experimental shape of the deformed elastica.

description: This paper shows an application of Bloom and Esik's iteration algebras to model graph data in a graph database query language. About twenty years ago, Buneman et al. developed a graph database query language UnQL on the top of a functional meta-language UnCAL for describing and manipulating graphs. Recently, the functional programming community has shown renewed interest in UnCAL, because it provides an efficient graph transformation language which is useful for various applications, such as bidirectional computation. However, no mathematical semantics of UnQL/UnCAL graphs has been developed. In this paper, we give an equational axiomatisation and algebraic semantics of UnCAL graphs. The main result of this paper is to prove that completeness of our equational axioms for UnCAL for the original bisimulation of UnCAL graphs via iteration algebras. Another benefit of algebraic semantics is a clean characterisation of structural recursion on graphs using free iteration algebra.

description: Industrial control systems (ICSs) are types of cyber-physical systems in which programs, written in languages such as ladder logic or structured text, control industrial processes through sensing and actuating. Given the use of ICSs in critical infrastructure, it is important to test their resilience against manipulations of sensor/actuator inputs. Unfortunately, existing methods fail to test them comprehensively, as they typically focus on finding the simplest-to-craft manipulations for a testing goal, and are also unable to determine when a test is simply a minor permutation of another, i.e. based on the same causal events. In this work, we propose a guided fuzzing approach for finding 'meaningfully different' tests for an ICS via a general formalisation of sensor/actuator-manipulation strategies. Our algorithm identifies the causal events in a test, generalises them to an equivalence class, and then updates the fuzzing strategy so as to find new tests that are causally different from those already identified. An evaluation of our approach on a real-world water treatment system shows that it is able to find 106% more causally different tests than the most comparable fuzzer. While we focus on diversifying the test suite of an ICS, our formalisation may be useful for other fuzzers that intercept communication channels.

description: In this paper, we introduce a numerical method based on Artificial Neural Networks (ANNs) for the analysis of black hole solutions to the Einstein-axion-dilaton system in a high dimensional parabolic class. Leveraging a profile root-finding technique based on General Relativity we describe an ANN solver to directly tackle the system of ordinary differential equations. Through our extensive numerical analysis, we demonstrate, for the first time, that there is no self-similar critical solution for the parabolic class in the high dimensions of space-time. Specifically, we develop $95\%$ ANN-based confidence intervals for all the solutions in their domains. At the $95\%$ confidence level, our ANN estimators confirm that there is no black hole solution in higher dimensions, hence the gravitational collapse does not occur. Results provide some doubts about the universality of the Choptuik phenomena. Therefore, we conclude that the fastest-growing mode of the perturbations that determine the critical exponent does not exist for the parabolic class in the high dimensions.

description: The prosthesis alignment is of central importance for a harmonic gait, especially for upper limb amputees. Today alignment optimization is based on static measuring and the experience of the orthopaedic technician. To objectify the alignment process a mobile gait analysis system based on 10 inertial sensors and a 6 DOF force and moment sensor was developed at the TU Berlin. The dedicated software adds dynamic gait parameters into the optimization process and guides the necessary changes in the prosthesis alignment. Therefore 19 common alignment changes were analysed based on measurements with 2 subjects fitted with the C-Leg knee. The anterior and posterior displacement of the knee will be the focus of an additional study with 6 subjects.

description: Random Forests and related tree-based methods are popular for supervised learning from table based data. Apart from their ease of parallelization, their classification performance is also superior. However, this performance, especially parallelizability, is offset by the loss of explainability. Statistical methods are often used to compensate for this disadvantage. Yet, their ability for local explanations, and in particular for global explanations, is limited. In the present work we propose an algebraic method, rooted in lattice theory, for the (global) explanation of tree ensembles. In detail, we introduce two novel conceptual views on tree ensemble classifiers and demonstrate their explanatory capabilities on Random Forests that were trained with standard parameters.
Shifting Centers of Production: The Amphorae Assemblages at Mons Porphyrites and Bir Umm Fawakhir

description: Mons Porphyrites and Bir Umm Fawakhir in the Eastern Desert of Egypt were two sites of resource extraction during the Roman and subsequent Byzantine occupation of Egypt. Mons Porphyrites was quarried for its vibrant purple stone featured in building projects such as the Pantheon. Bir Umm Fawakhir was a gold mine which was worked intermittently from the twentieth dynasty of the Egyptian pharaohs through the Ptolemies and into the Byzantine period. In this paper, I examine the amphorae evidence from both sites to trace the patterns over time in the distribution of goods including centers of production, routes of transportation, and the larger networks of supplying the labor forces at these zones of extraction. The end result is that the provisioning of the quarries and the mines took place in a complex system of trade which functioned alongside local lines of supply.

description: This work studies how parametric uncertainties affect the cooperative manipulation of a cable-suspended beam-shaped load by means of two aerial robots not explicitly communicating with each other. In particular, the work sheds light on the impact of the uncertain knowledge of the model parameters available to an established communication-less force-based controller. First, we find the closed-loop equilibrium configurations in the presence of the aforementioned uncertainties, and then we study their stability. Hence, we show the fundamental role played in the robustness of the load attitude control by the internal force induced in the manipulated object by non-vertical cables. Furthermore, we formally study the sensitivity of the attitude error to such parametric variations, and we provide a method to act on the load position error in the presence of the uncertainties. Eventually, we validate the results through an extensive set of numerical tests in a realistic simulation environment including underactuated aerial vehicles and sagging-prone cables, and through hardware experiments.

description: Respiratory diseases are mostly detected by pulmonary function tests (PFTs). In obstructive lung diseases, such as in asthma and chronic obstructive pulmonary disease (COPD), small airways play a vital role in the etiology and progression of the disease. Although spirometry is considered the gold standard PFT, it is not useful in detecting changes in the small airways. Sophisticated techniques, such as high-resolution computed tomography (HRCT) scanning, can detect changes in the small airways, but are expensive and difficult to administer to the general population. Oscillometry is a sound wave-based technique that has a very high sensitivity for detecting changes in the airways, particularly the small airways, and is easy to administer to all age groups, particularly people with limited abilities. However, proper interpretation of oscillometric results depends on accurate reference values. Despite available reference values for oscillometric indices, none of them are robust, and all are specific to distinct populations. This scoping review aims to evaluate adult reference values for oscillometry and will assess the generalizability of those reference values.
