description: In generalization of the mutually catalytic super-Brownian motion in R of Dawson/Perkins (1998) and Mytnik (1998), a function-valued cyclically catalytic model X is constructed as a strong Markov solution to a martingale problem. Starting with a finite population X0, each pair of neighboring types will globally segregate in the long-term limit (non-coexistence of neighboring types). Also finer extinction/survival properties in dependence on X0 are studied in the spirit of Mueller and Perkins (1999). In fact, X0 can be chosen in such a way that all types survive all finite times. On the other hand, sufficient conditions on X0 are stated for the following situation: Given a type k and a positive time t, the kth subpopulation Xk dies by time t with a large probability, provided that its initial value Xk0 was sufficiently small.

description: Can the joint measures of quenched disordered lattice spin models (with finite range) on the product of spin-space and disorder-space be represented as (suitably generalized) Gibbs measures of an "annealed system"? - We prove that there is always a potential (depending on both spin and disorder variables) that converges absolutely on a set of full measure w.r.t. the joint measure ("weak Gibbsianness"). This "positive" result is surprising when contrasted with the results of a previous paper [K6], where we investigated the measure of the set of discontinuity points of the conditional expectations (investigation of "a.s. Gibbsianness""). In particular we gave natural "negative" examples where this set is even of measure one (including the random field Ising model). Further we discuss conditions giving the convergence of vacuum potentials and conditions for the decay of the joint potential in terms of the decay of the disorder average over certain quenched correlations. We apply them to various examples. From this one typically expects the existence of a potential that decays superpolynomially outside a set of measure zero. Our proof uses a martingale argument that allows to cut (an infinite volume analogue of) the quenched free energy into local pieces, along with generalizations of Kozlov's constructions.
On Adsorption and Diffusion in Porous Media

description: The paper contains a macroscopic continuum model of adsorption in porous materials consisting of three components. We consider the flow of a fluid/adsorbate mixture through channels of a solid component. The fluid serves as carrier for an adsorbate whose mass balance equation contains a source term. This term consists of two parts: first a Langmuir contribution which is connected with bare sites on internal surfaces and describes the Langmuir isotherm in equilibrium. The second one is due to changes of the internal surface driven by the source of porosity which is a part of the balance equation for porosity. We clearly state the range of applicability of the model. A simple numerical example which describes the transport of pollutants in soils illustrates the coupling of adsorption and diffusion. The results show that after a certain time arises a maximum in the rate of adsorption as a function of fluid/adsorbate velocity.
title: Scaffolding im GW-Unterricht der Mittelschule für Schüler:innen mit Deutsch als Zweitsprache
Creators: name: Hirschler, Lena
Year: 2023

description: Wenn von der Umsetzung sprachsensiblen Unterrichts die Rede ist, wird die Dringlichkeit der Thematik allen Lehrkräften bewusst sein. Eine Möglichkeit, diesen umzusetzen, stellt das Scaffolding dar. Dieses ist für den Primarbereich schon sehr gut untersucht, oft hatte aber die Mittelschule bei der Erforschung der Auswirkungen der Methode das Nachsehen. Jedoch darf die Sprachbildung nach der Volksschule nicht aufhören. Dadurch soll in der vorliegenden Arbeit das Scaffolding als Methode untersucht werden, die im GW-Unterricht angewandt werden kann, um sprachsensiblen Unterricht abzuhalten. Die genauen Forschungsfragen, die sich hierfür ergeben haben, lauten: „Wie lässt sich das Scaffolding im GW-Unterricht einsetzen?“ und „Welche Potenziale und Schwachstellen bringt das Scaffolding mit sich?“ Um diese zu beantworten, wurde einerseits eine Erhebung mittels Beobachtungsbögen durchgeführt, andererseits wurde der Lehrer in einem Interview zu seinen Eindrücken in Bezug auf die Methode befragt und auch die Schüler:innen sollten die eingesetzten Scaffolds im Zuge eines Fragebogens bewerten. Die wichtigsten Ergebnisse zeigten ein positives Bild auf das Scaffolding. Sowohl der Lehrer als auch die Schüler:innen bewerten die Methode (sehr) gut. Dabei kann sie helfen, eine aktive Teilhabe am Unterricht zu ermöglichen, was den einzig genannten Nachteil, den erhöhten Zeitaufwand, deutlich ausgleicht.

description: A new electromagnetic cavity structure, a lattice of 3D cavities consisting of an array of posts and gaps is presented. The individual cavity elements are based on the cylindrical re-entrant (or Klystron) cavity. We show that these cavities can also can be thought of as 3D split-ring resonators, which is confirmed by applying symmetry transformations, each of which is an electromagnetic resonator with spatially separated magnetic and electric field. The characteristics of the cavity is used to mimic phonon behaviour of a one dimensional chain of atoms. It is demonstrated how magnetic field coupling can lead to phonon-like dispersion curves with acoustical and optical branches. The system is able to reproduce a number of effects typical to one-dimensional lattices exhibiting acoustic vibration, such as band gaps, phonon trapping, and effects of impurities. In addition, quasicrystal emulations predict the results expected from this class of ordered structures. The system is easily scalable to simulate 2D and 3D lattices and shows a new way to engineer arrays of coupled microwave resonators with a variety of possible applications to hybrid quantum systems proposed.

Data Horror Week
game

description: A poster presented during Research Data Alliance (RDA)16th Plenary Meeting - Costa Rica (Virtual). Our new digital escape room makes use of gamification to introduce some basic data management concepts and offers a fun way to educate and to prompt discussions with researchers. Read more in this blog post. Research data management (RDM) as a service offered by university libraries is new for researchers as well as support staff. The RDM teams often struggle with reaching new users. In order to improve the visibility of our service, RDM colleagues from various Dutch universities joined forces to organize an awareness campaign around Halloween. One thing that we often notice is that the value of good RDM is often learned the hard way: that is, when things go wrong. To be able to talk about failure in a playful and safe way we chose to conduct "the Data Horror Week", also as a sort of counterpart to the popular “data love” events around St Valentines. The poster highlights the main element of our campaign: the Data Horror Escape Room. Because of the COVID-19 pandemic, we had to plan for online events only. One online activity that has recently become popular is the digital escape room. An escape room is a game where a team of players has to solve a set of puzzles to “escape” a room in which they are “locked” or to defeat a villain. There is usually a theme and a story that brings the puzzles together. Digital escape rooms, as well as “in-person” escape rooms, are often used in educational settings. This format could offer a fun way to learn about research data management. The room we created consists of six tasks related to the following data management topics: FAIR data, personal data, data archiving, data transfer, persistent identifiers, and metadata. As the room was to become part of the Data Horror Week around Halloween, a theme with ghosts and vampires was chosen.

description: medical attention frequently believed their symptoms had nothing to do with their hearts. These symptoms and misinterpretations may influence the decision to seek therapy due to a lack of knowledge about ACS symptoms or the erroneous adoption of attitudes and concepts around symptoms. Objective: To analyze the sociodemographic variables that were connected with knowledge and to describe ACS knowledge among ACS patients in Bangladesh who had been diagnosed with the condition. Methods: At a hospital of secondary level, 288 ACS patients older than 18 years old participated in a cross-sectional study. Both the indoor and outdoor patients' data were gathered. Stata version 13 was used for data analysis. The scoring system was employed to gauge the respondents' degree of knowledge. Results: Only 16.0 (46) percent of respondents had a low understanding of ACS, 20.8 (60) percent had normal knowledge, and 39.2 (113) percent had very good knowledge. The results also revealed a significant relationship between knowledge level and respondents' sex (P=0.045), age (P=0.012), and place of residence (P=0.031). Conclusion: The results of this study suggest that to raise participants' knowledge regarding ACS symptoms, health awareness campaigns using a variety of media venues targeted at high-risk populations are required. A future extensive investigation is also necessary to fully comprehend the issue and fill up the gaps that have been found.

description: Die Masterarbeit „‘ich lese literatur, verzweifelt_besessen auf der suche nach räumen, in denen ich anwesenheit spüre.‘ Eine vergleichende Studie aktueller Ansätze zu geschlechtersensiblen Sprachformen bei Ann Cotten und Hermes Phettberg“ legt, wie der Titel suggeriert, den Schwerpunkt auf zwei Varianten geschlechtersensibler Sprache und beleuchtet infolgedessen, wie und ob aktuelle sprachliche Varianten zugunsten einer Destabilisierung des binären Geschlechterschemas genutzt werden können, um Sprachräume entstehen zu lassen, die die Anwesenheit von Identitätszugehörigkeiten jeglicher Art ermöglichen. Bei Ann Cottens „Polnischem Gendering“ und Hermes Phettbergs „Entgendern“ handelt es sich um Sprachformen, die durch die Übertragung auf das Forschungsgebiet der Queeren Linguistik Möglichkeiten queerer Interventionen gegen tradierte heteronormative Identitätskonstruktionen offenhalten und dank ihrem hohen Maß an Aktualität das Potenzial bieten, Reflexionen hinsichtlich eines respektvollen Umgangs mit Menschen anzuregen. Der Forschungsstand zu geschlechtersensibler, geschlechtergerechter und geschlechtsneutraler Sprache sowie eine Einführung in Queer Theory spielen als theoretische Basis dieser Arbeit eine zentrale Rolle. Um überprüfen zu können, ob Cotten und Phettberg auf die jeweilige von ihnen ins Leben gerufene Sprachform konsequent in den von ihnen verfassten Werken zurückgreifen, wurden anhand von selektierten Korpora –, welche strichprobenartig die Sprachverwendung von Cotten und Phettberg darstellen,– im Zuge einer empirischen Untersuchung und einer anschließenden statistischen Auswertung mithilfe des Datenverarbeitungsprogramms SPSS die Wortbildungsmethoden innerhalb der ausgewählten Textstellen untersucht. Ein umfassender Vergleich der absoluten und prozentualen Verteilung der Formulierungen konnte zwar nachweisen, dass sowohl Cotten als auch Phettberg in fast jeder der ausgewählten Textpassagen von dem geschlechtersensiblen „Polnischen Gendering“ bzw. dem geschlechtersensiblen „Entgendern nach Phettberg“ Gebrauch machen, die geschlechtersensiblen Formulierungen jedoch in keinem der Forschungskorpora zu den am häufigsten gebrauchten Sprachformen zählen. Wiederholt wurde sogar auf sprachliche Formen zurückgegriffen, die nicht mit dem Inklusivitätsgedanken geschlechtersensibler Formulierungen zu vereinbaren sind.

description: To measure the mass loss from dusty oxygen-rich (O-rich) evolved stars in the Large Magellanic Cloud (LMC), we have constructed a grid of models of spherically-symmetric dust shells around stars with constant mass-loss rates using 2Dust. These models will constitute the O-rich model part of the "Grid of Red supergiant and Asymptotic giant branch star ModelS" (GRAMS). This model grid explores 4 parameters - stellar effective temperature from 2100 K - 4700 K; luminosity from 10^3-10^6 L_Sun; dust shell inner radii of 3, 7, 11, and 15 R_Star; and 10.0 micron optical depth from 10^-4 to 26. From an initial grid of ~1200 2Dust models, we create a larger grid of ~69,000 models by scaling to cover the luminosity range required by the data. These models are offered to the public on a website. The matching in color-magnitude diagrams and color-color diagrams to observed O-rich asymptotic giant branch (AGB) and red supergiant (RSG) candidate stars from the SAGE and SAGE-Spec LMC samples and a small sample of OH/IR stars is generally very good. The extreme AGB star candidates from SAGE are more consistent with carbon-rich (C-rich) than O-rich dust composition. Our model grid suggests lower limits to the mid-infrared colors of the dustiest AGB stars for which the chemistry could be O-rich. Finally, the fitting of GRAMS models to SEDs of sources fit by other studies provides additional verification of our grid and anticipates future, more expansive efforts.

Creators: name: Masood, Maheen
Year: 2023

description: Blutsaugende Mücken sind die bedeutendsten Vektoren für die Übertragung von Arboviren unter allen Arthropoden, was sie zu einem großen epidemiologischen Problem macht. Da mehrere Arten der Gattung Aedes die Fähigkeit haben, Arboviren zu verbreiten, stellt diese Gattung eine Bedrohung für die öffentliche Gesundheit dar. Die Bedeutung von Mücken für die öffentliche Gesundheit in Europa hat sich aufgrund der kürzlichen Invasion nicht heimischer Aedes-Arten erheblich ausgeweitet. In den letzten zehn Jahren haben sich mindestens fünf nicht heimische Aedes-Mückenarten, von denen einige potenzielle Arbovirus-Vektoren sind, in Europa etabliert, darunter das Dengue-Virus und das Chikungunya-Virus. Neben Arboviren tragen Mücken auch natürlicherweise eine Vielzahl anderer nicht- arboviraler Viren. Aktuelle Forschungen haben gezeigt, dass Mücken ein hoch diverses virales Mikrobiom beherbergen, einschließlich vieler zuvor nicht identifizierter Viren. Mücken bieten eine ideale Umgebung für das Mischen von Viren, was potenziell die Bildung neuer genetischer Virusvarianten fördert und die Vielfalt der Virussequenzen erhöht. Herkömmliche Vektor-Untersuchungsansätze können jedoch Viren mit einem hohen Grad an Sequenzneuartigkeit übersehen. Unser Projekt beinhaltet den Einsatz moderner Sequenzierungstechnologie für das Viren-Mikrobiom, um das Spektrum der Viren in nicht heimischen Aedes-Mücken, die in Österreich gesammelt wurden, zu bewerten. Zu diesem Zweck werden wir ein spezialisiertes Arbovirus-Sequenzierungs-Panel verwenden, das für eine hochsensible Analyse der Arbovirus-Sequenzvielfalt entwickelt wurde. Durch umfassende metagenomische Analyse ist unser Ziel, die Zusammensetzung des viralen Mikrobioms in Mücken zu entschlüsseln und zuvor unentdeckte Virussequenzen zu identifizieren. Mit diesem Ansatz werden wir wertvolle Erkenntnisse über die Vielfalt und Dynamik der Viren im Zusammenhang mit diesen Mücken gewinnen.

Consistent perturbative treatment of the subohmic spin-boson model yielding arbitrarily small $T_2/T_1$ decoherence time ratios

description: We present a perturbative treatment of the subohmic spin-boson model which remedies a crucial flaw in previous treatments. The problem is traced back to the incorrect application of a Markov type approximation to specific terms in the temporal evolution of the reduced density matrix. The modified solution is consistent both with numerical simulations and the exact solution obtained when the bath-coupling spin-space direction is parallel to the qubit energy-basis spin. We therefore demonstrate that %in distinction to previous findings the subohmic spin-boson model is capable of %consistently describing arbitrarily small %(less than two) ratios of the $T_2$ and $T_1$ decoherence times, associated to the decay of the off-diagonal and diagonal reduced density-matrix elements, respectively. An analytical formula for $T_2/T_1$ at the absolute zero of temperature is provided in the limit of a subohmic bath with vanishing spectral power law exponent. Small ratios closely mimic the experimental results for solid state (flux) qubits, which are subject predominantly to low-frequency electromagnetic noise, and we suggest a reanalysis of the corresponding experimental data in terms of a $nonanalytic$ decay of off-diagonal coherence.

description: We observe a sample of 8 evolved stars in the Galactic Bulge in the CO J = 2 - 1 line using the Submillimeter Array (SMA) with angular resolution of 1 - 4 arcseconds. These stars have been detected previously at infrared wavelengths, and several of them have OH maser emission. We detect CO J = 2 - 1 emission from three of the sources in the sample: OH 359.943 +0.260, [SLO2003] A12, and [SLO2003] A51. We do not detect the remaining 5 stars in the sample because of heavy contamination from the galactic foreground CO emission. Combining CO data with observations at infrared wavelengths constraining dust mass loss from these stars, we determine the gas-to-dust ratios of the Galactic Bulge stars for which CO emission is detected. For OH 359.943 +0.260, we determine a gas mass-loss rate of 7.9 (+/- 2.2) x 10^-5 M_Sun/year and a gas-to-dust ratio of 310 (+/- 89). For [SLO2003] A12, we find a gas mass-loss rate of 5.4 (+/- 2.8) x 10^-5 M_Sun/year and a gas-to-dust ratio of 220 (+/- 110). For [SLO2003] A51, we find a gas mass-loss rate of 3.4 (+/- 3.0) x 10^-5 M_Sun/year and a gas-to-dust ratio of 160 (+/- 140), reflecting the low quality of our tentative detection of the CO J = 2 - 1 emission from A51. We find the CO J = 2 - 1 detections of OH/IR stars in the Galactic Bulge require lower average CO J = 2 - 1 backgrounds.

description: We consider three-dimensional gravity with negative cosmological constant in the presence of a scalar and an Abelian gauge field. Both fields are conformally coupled to gravity, the scalar field through a nonminimal coupling with the curvature and the gauge field by means of a Lagrangian given by a power of the Maxwell one. A sixth-power self-interaction potential, which does not spoil conformal invariance is also included in the action. Using a circularly symmetric ansatz, we obtain black hole solutions dressed with the scalar and gauge fields, which are regular on and outside the event horizon. These charged hairy black holes are asymptotically anti-de Sitter spacetimes. The mass and the electric charge are computed by using the Regge-Teitelboim Hamiltonian approach. If both leading and subleading terms of the asymptotic condition of the scalar field are present, a boundary condition that functionally relates them is required for determining the mass. Since the asymptotic form of the scalar field solution is defined by two integration constants, the boundary condition may or may not respect the asymptotic conformal symmetry. An analysis of the temperature and entropy of these black holes is presented. The temperature is a monotonically increasing function of the horizon radius as expected for asymptotically anti-de Sitter black holes. However, restrictions on the parameters describing the black holes are found by requiring the entropy to be positive, which, given the nonminimal coupling considered here, does not follow the area law. Remarkably, the same conditions ensure that the conformally related solutions become black holes in the Einstein frame.

description: Das Wachstum von Prostatakrebszellen wird durch Vitamin K gehemmt, und die Aggressivität von Prostatakrebs wird mit Veränderungen in der Expression von Proteinen in Verbindung gebracht, die mit Vitamin K in Zusammenhang stehen. Die Auswirkungen des Vitamin-K Konsums auf Prostatakrebs in der menschlichen Bevölkerung sind nicht genau geklärt . Daher wurde eine systematische Überprüfung prospektiver Studien zur Vitamin-K-Aufnahme und zum Prostatakrebsrisiko durchgeführt. Es wurde eine Metaanalyse nach den PICOS-Kriterien durchgeführt. Von 144 Suchergebnissen kamen vier Kohortenstudien für die vorliegende systematische Überprüfung in Frage. Ihre Ergebnisse wurden im Anschluss an die PRISMA-Erklärung extrahiert und zusammengefasst. Daher wurde eine systematische Überprüfung prospektiver Studien zur Vitamin-K-Aufnahme und zum Prostatakrebsrisiko durchgeführt. In 4 verschiedenen Kohortenstudien habe ich untersucht, ob die Einnahme verschiedener Arten von Vitamin K einen Zusammenhang mit totalem Prostatakrebs und fortgeschrittenem Prostatakrebs hat. Die Phyllochinon-Werte wurden beim gesamten Prostatakrebs untersucht und als Ergebnis stellte ich fest, dass es keinen signifikanten Unterschied zwischen der Phyllochinon-Einnahme und dem gesamten Prostatakrebsrisiko in der Ernährungsfragebogenstudie gab. 95 % KI 0,96 [0,89, 1,03], daher die Assoziationsbewertung zwischen Phyllochinon und Von einem vollständigen Prostatakrebs konnte nicht ausgegangen werden. Die Menachinon-Werte wurden bei totalem Prostatakrebs und fortgeschrittenem Prostatakrebs untersucht. Ebenso wie bei den Phyllochinon-Werten gab es in der Ernährungsfragebogenstudie keinen Zusammenhang zwischen der Menachinon-Einnahme und dem Risiko, an Prostatakrebs zu erkranken. 95 % KI von 0,95 [0,85, 1,07], daraus wurde geschlossen Eine Assoziationsbeurteilung konnte nicht angenommen werden. Die Vitamin-K-Aufnahme wurde in den oberen Quartilen als Phyllochinon, Menachinon, ucOC/iOC und Gesamtaufnahme analysiert. Alle Ergebnisse wurden anhand der Bewertung des Bias-Risikos und der GRADE-Bewertung bewertet. Insgesamt war die Aufnahme von Vitamin K weder in Phyllochinon- und Menachinonform noch in Biomarkern mit dem Risiko eines vollst¨andigen Prostatakrebses verbunden, das Risiko einer Verzerrung war gering und es waren weitere Studien erforderlich. Die vorliegenden Ergebnisse deuten nicht darauf hin, dass die Aufnahme oder der Vitamin-K-Status mit dem Prostatakrebsrisiko verbunden ist. Allerdings müssen diese Ergebnisse angesichts der geringen Anzahl von Studien mit hohem Verzerrungsrisiko und der geringen Vertrauenswürdigkeit der Evidenz mit Vorsicht interpretiert werden.
title: Investigating the Impact of Positive Leadership and Identification on Employee Wellbeing
Creators: name: Marsh, Christie Jade
Publisher: name: University of Kent

description: Workplace stress, depression and anxiety has been increasing steadily in recent years and the COVID pandemic has accelerated this growth drastically (Health & Safety Executive, 2020). Consequently, the focus on employee wellbeing in organisations has been increased (CIPD, 2021). One key influencer of employee wellbeing is leadership and specifically, positive leadership (Cameron, 2012; 2013) which has been recently associated with employee wellbeing and mediated by identification variables (Marsh et al., in prep). This thesis extends on these initial findings by widening the focus of employee wellbeing to include multiple indicators, explores other potential mediating variables and considers other factors which might heighten or dampen the impact of positive leadership on employee wellbeing. Across eight studies (N = 1863), there is clear empirical evidence for the impact of positive leadership on a wide variety of employee wellbeing indicators which incorporate both hedonic and eudemonic indicators and both positive and negative indicators. There is also clear support for the role of identification variables as significant mediators in the relationship between positive leadership and employee wellbeing. Results also showed the potential for perceived organisational support and LMX as mediating mechanisms. There is also evidence from this thesis that positive leadership does show unique effects when taking into account other leadership styles associated with wellbeing. Additionally, positive leaders received better evaluations of their leadership than other leaders and the beneficial impact of positive leaders was not limited by the characteristics of the leader. Overall, this thesis adds to the literature on positive leadership by examining the why and how this style of leadership has beneficial impacts on employee wellbeing. The thesis concludes with a discussion of the theoretical and applied implications, limitations and future research avenues.

description: We demonstrate that silicon-vacancy (SiV) centers in diamond can be used to efficiently generate coherent optical photons with excellent spectral properties. We show that these features are due to the inversion symmetry associated with SiV centers, and demonstrate generation of indistinguishable single photons from separate emitters in a Hong-Ou-Mandel (HOM) interference experiment.Prospects for realizing efficient quantum network nodes using SiV centers are discussed.

description: We identify ambiguities in the available frameworks for defining quantum, classical, and total correlations as measured by discordlike quantifiers. More specifically, we determine situations for which either classical or quantum correlations are not uniquely defined due to degeneracies arising from the optimization procedure over the state space. In order to remove such degeneracies, we introduce a general approach where correlations are independently defined, escaping therefore from a degenerate subspace. As an illustration, we analyze the trace-norm geometric quantum discord for two-qubit Bell-diagonal states.

description: Oxygen is the most abundant element on the Sun after Hydrogen and Helium. The intensity spectrum of resonance lines of neutral Oxygen namely O {\sc i} (1302, 1305 and 1306 Å\,) has been studied in the literature for chromospheric diagnostics. In this paper we study the resonance scattering polarization in the O {\sc i} line at 1302 Å\, using two-dimensional radiative transfer in a composite atmosphere constructed using a two-dimensional magneto-hydrodynamical snapshot in the photosphere and columns of the one-dimensional FALC atmosphere in the chromosphere. The methods developed by us recently in a series of papers to solve multi-dimensional polarized radiative transfer have been incorporated in our new code POLY2D which we use for our analysis. We find that multi-dimensional radiative transfer including XRD effects is important in reproducing the amplitude and shape of scattering polarization signals of the O {\sc i} line at 1302 Å\,.

description: We study the ultrafast quasiparticle dynamics in and below the ZnO conduction band using femtosecond time-resolved two-photon photoelectron spectroscopy. Above band gap excitation causes hot electron relaxation by electron-phonon scattering down to the Fermi level $E_\text{F}$ followed by ultrafast (200 fs) formation of a surface exciton (SX). Transient screening of the Coulomb interaction reduces the SX formation probability at high excitation densities near the Mott limit. Located just below the surface, the SX are stable with regard to hydrogen-induced work function modifications and thus the ideal prerequisite for resonant energy transfer applications.

Universität Hildesheim

description: Im Fokus der serviceorientierten Leistungen der UB Hildesheim stehen seit März 2018 alle Forschenden, vom Bachelor bis hin zum Prof., sowie alle Mitarbeitenden der Universität. Mit „Awareness“-Maßnahmen (Schulungen und Workshops) hat sich die UB sehr gut am Campus positionieren können, denn die Bibliothek kann allen vier Fachbereichen, Instituten und interdisziplinären Forschungsprojekten bestmögliche Unterstützung, in allen wichtigen Kooperationen, (lokal, national, international) anbieten. Einzelne Services wurden zunächst kontinuierlich aufgebaut, z.B. RDMO (Research Data Management Organiser) und HILREDA (Dataverse-Forschungsdatenrepositorium). Annette Strauch-Davey, die seit über 10 Jahren im Bereich der Langzeitarchivierung und Forschungdaten tätig ist (National Library of Wales; kiz der Universität Ulm; SFB 1187 im Zentrum für Informations- und Medientechnologie (ZIMT) an der Universität Siegen), bietet ganz forschungsnahen Support an (Kollaborationen) und ist gut vernetzt (RDA, DINI, GO UNITE, NFDI-Konsortien, VDB-Kommission für forschungsnahe Dienste[1]).

 Die Herausforderungen sowie die Angebote der UB Hildesheim beim Aufbau des FDM-Services werden beim Thementag veranschaulicht.

title: Rita Laura Segatos Werk bezüglich Gewalt an Frauen im Kontext von Körper und Sexualität im Wandel der Zeit
Creators: name: Lorbek, Lisa Elke
Year: 2023

description: Rita Laura Segato ist eine der bekanntesten feministischen Stimmen in Lateinamerika, sie beschäftigt sich seit über 20 Jahren mit Themen wie geschlechtsspezifische Gewalt, Femizid und Dekolonialität in Lateinamerika. Im Zentrum dieser Masterarbeit steht die Analyse einer Verbindung zwischen Gewalt an Frauen und Körper/Sexualität in Segatos Werk und ob es in den letzten 20 Jahren einen dbzgl. Wandel in ihrem Denken gab. Als Methode wird eine Textanalyse nach Mayring verwendet mit Hilfe jener eine Änderung ersichtlich wird. Es wird deutlich, dass sich die zentralen Thesen Segatos im Laufe der Jahre verändern bzw. ihre zentralen Thesen, beispielsweise aus dem Buch „Las estructuras elementales de la violencia“ (2003), erweitert werden. Rita Segato geht in ihren Theorien davon aus, dass geschlechtsspezifische Gewalt und sogar Femizid eine Kommunikationsform zwischen Konfliktparteien darstellt. Sie erweitert diese Theorie um den Aspekt paramilitärischer Kriege, in welchen der Körper der Frau „nur noch“ als Territorium gesehen wird und die ausgeübte (meist) sexuelle Gewalt nicht mehr libidinöser Art sei, sondern der Kommunikation diene.
description: Rita Laura Segato is one of the most famous feminist voices in Latin America and has dedicated her work to topics such as gender-based violence, femicide and decoloniality in Latin America for over 20 years. This paper analyses the relationship between violence against women and body/sexuality in Segato’s work and considers whether there has been a shift in her thinking over the last 20 years. Mayring’s textual analysis method reveals such a change. It becomes clear that Segato’s central theses do develop over the years in that her central theses, such as those from’ Las estructuras elementales de la violencia’ (2003), are broadened. Rita Segato’s theories assume that gender-based violence and even femicide constitute a form of communication between parties to a conflict. She extends these theories to contexts like paramilitary wars, where the female body is seen as ‘no more than’ territory and where the (mostly) sexual violence exerted is no longer libidinous in nature, but supports communication.

description: Since self-paced treadmills enable more natural gait patterns compared to fixed-speed treadmills we examined the use of a self-paced treadmill as a alternative for overground gait analysis in persons after stroke. Twenty-five persons after stroke (10 males/15 females; 53 ± 12.05 years; 40.72 ± 42.94 months post-stroke) walked at self-selected speed overground (GAITRite, CIR Systems) and on a self-paced treadmill (GRAIL, Motek) in randomized order. Spatiotemporal parameters, variability and symmetry measures were compared using paired-sample t-tests or Wilcoxon Signed Rank tests. Concurrent validity was assessed using intraclass correlation coefficients and Bland-Altman plots. A regression model determined the contribution of the walking velocity to the changes in spatiotemporal parameters. The velocity on the treadmill was significant lower compared to overground (p < 0.001). This difference predicted the significant changes in other spatiotemporal parameters to varying degrees (27.7%–83.8%). Bland-Altman plots showed large percentage of bias and limits of agreement. Variability and symmetry measures were similar between conditions. When considering gait analysis in persons after stroke a self-paced treadmill may be a valuable alternative for overground analysis. Although a slower walking velocity, and accompanying changes in other spatiotemporal parameters, should be taken into account compared to overground walking.Implications for rehabilitationConsidering the advantages regarding space and time, instrumented treadmills provide opportunities for gait assessment and training in a stroke population.When using self-paced treadmills for clinical gait analysis in persons after stroke, the slower walking velocity and accompanying changes in other spatiotemporal parameters need to be taken into account.Stroke patients seem to preserve their walking pattern on a self-paced treadmill.

Nonuniform Expansion of the Youngest Galactic Supernova Remnant G1.9+0.3

description: We report measurements of X-ray expansion of the youngest Galactic supernova remnant, G1.9+0.3, using Chandra observations in 2007, 2009, and 2011. The measured rates strongly deviate from uniform expansion, decreasing radially by about 60% along the X-ray bright SE-NW axis from 0.84% +/- 0.06% per yr to 0.52% +/- 0.03% per yr. This corresponds to undecelerated ages of 120-190 yr, confirming the young age of G1.9+0.3, and implying a significant deceleration of the blast wave. The synchrotron-dominated X-ray emission brightens at a rate of 1.9% +/- 0.4% per yr. We identify bright outer and inner rims with the blast wave and reverse shock, respectively. Sharp density gradients in either ejecta or ambient medium are required to produce the sudden deceleration of the reverse shock or the blast wave implied by the large spread in expansion ages. The blast wave could have been decelerated recently by an encounter with a modest density discontinuity in the ambient medium, such as found at a wind termination shock, requiring strong mass loss in the progenitor. Alternatively, the reverse shock might have encountered an order-of-magnitude density discontinuity within the ejecta, such as found in pulsating delayed-detonation Type Ia models. We demonstrate that the blast wave is much more decelerated than the reverse shock in these models for remnants at ages similar to G1.9+0.3. Similar effects may also be produced by dense shells possibly associated with high-velocity features in Type Ia spectra. Accounting for the asymmetry of G1.9+0.3 will require more realistic 3D Type Ia models.

Probing CP violation at LBNE with reactor experiments

description: In this work, we have explored the possibilities of improving CP violation discovery potential of newly planned Long-Baseline Neutrino Experiment (LBNE), U.S.A., by combining with data from reactors. The third mixing angle $θ_{13}$ is now very precisely measured and this precise measurenent of $θ_{13}$ helps in measurement of CP violation. Here, CP violation is studied with and without data from reactors. Impact of placing a ND is also studied. It is found that CPV discovery potential of LBNE with ND increases when combined with data from reactors. With a far detector of 35 kt, it is possible to obtain 5$σ$ sensitivity of CPV when run for 5 years in $ν$ and 5 years in $\barν$ mode. When hierarchy is assumed to be normal hierarchy, CPV sensitivity is maximum. CPV discovery is possible by combining 5 years neutino data from LBNE with 3 years anti-neutrino from reactors. This study reveals that CPV can also be discovered at 5$σ$ cl in IH mode when appearance measurement of LBNE is combined with reactors.
