description: Landscapes in South East Asia are changing rapidly. In the Lao People’s Democratic Republic (Laos) large-scale infrastructure development is ongoing. At the same time, Laos has one of the highest forest covers in the region and set the ambitious goal to increase forest cover to 70% country area. It is unclear, if increased accessibility through infrastructure development can lead to a forest transition - a shift from net deforestation to net reforestation, and how such changes affect livelihood activities of local populations. We hypothesize that local stakeholders perceive ongoing land use changes and their drivers differently, depending on past forest cover changes and accessibility. In this study, we assess forest cover changes from remote sensing, and local perceptions of land use change between 2010-2020 as well as the perceived drivers of change in context of accessibility. We visited 27 villages along a gradient of accessibility in both the province of Vientiane and Vientiane capital to conduct focus group discussions and walking interviews with village committees, and interviews with government officials to assess local perceptions of land use changes and their underlying drivers. We find that remote sensing data and the perception of village committees align on a negative forest cover trend. The village committees perceive the landscape to change mainly due to economic and policy drivers. They prioritize infrastructure and economic development over forest conservation. Our findings provide little evidence for a forest transition in the case study area. While enabling conditions for a forest transition are found to be more developed in better accessible areas, they are mainly related to foreign land based investments. These insights call into question the inclusiveness of economic policies and the high prioritization of forest conservation from the government side. They underscore the need to design policies rooted in local perspectives to ensure positive outcomes for people and nature.

description: In this paper we investigate the behavior of three-dimensional homogeneous solutions of the cross curvature flow using Riemannian groupoids. The Riemannian groupoid technique, introduced by John Lott, allows us to investigate the long term behavior of collapsing solutions of the flow, producing soliton solutions in the limit. We also review Lott's results on the long term behavior of three-dimensional homogeneous solutions of Ricci flow, demonstrating the coordinates we choose and reviewing the groupoid technique. We find cross curvature soliton metrics on Sol and Nil, and show that the cross curvature flow of SL(2,R) limits to Sol.

description: We study the correspondence between the linear matrix model and the interacting nonlinear string theory. Starting from the simple matrix harmonic oscillator states, we derive in a direct way scattering amplitudes of 2-dimensional strings, exhibiting the nonlinear equation generating arbitrary N-point tree amplitudes. An even closer connection between the matrix model and the conformal string theory is seen in studies of the symmetry algebra of the system.

description: The small object argument is a transfinite construction which, starting from a set of maps in a category, generates a weak factorisation system on that category. As useful as it is, the small object argument has some problematic aspects: it possesses no universal property; it does not converge; and it does not seem to be related to other transfinite constructions occurring in categorical algebra. In this paper, we give an "algebraic" refinement of the small object argument, cast in terms of Grandis and Tholen's natural weak factorisation systems, which rectifies each of these three deficiencies.

High-resolution combined tunneling electron charge and spin transport theory of Néel and Bloch skyrmions

Year: 2018
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Based on a combined charge and vector spin transport theory capable of imaging noncollinear magnetic textures on surfaces with spin-polarized scanning tunneling microscopy (SP-STM), the high-resolution tunneling electron charge and coupled spin transport properties of a variety of Néel- and Bloch-type skyrmions are investigated. Axially symmetric skyrmions are considered within the same topology class characterized by a vorticity value of $m=1$, and their helicities are varied by taking $γ=0$ and $π$ values for the Néel skyrmions and $γ=-π/2$ and $π/2$ values for the Bloch skyrmions. Depending on the orientation of the magnetization of the STM tip as well as on the helicity and the time-reversal of the skyrmionic spin structures, several relationships between their spin transport vector components, the in-plane and out-of-plane spin transfer torque and the longitudinal spin current, are identified. The magnitudes of the spin transport vector quantities show close relation to standard charge current SP-STM images. It is also demonstrated that the SP-STM images can be used to determine the helicity of the skyrmions. Moreover, the modified spin polarization vectors of the conduction electrons due to the local chirality of the complex spin texture are incorporated into the tunneling model. It is found that this effect modifies the apparent size of the skyrmions. These results contribute to the proper identification of topological surface magnetic objects imaged by SP-STM, and deliver important parameters for current-induced spin dynamics.

description: We present new deep Chandra observations of the Centaurus A jet, with a combined on-source exposure time of 719 ks. These data allow detailed X-ray spectral measurements to be made along the jet out to its disappearance at 4.5 kpc from the nucleus. We distinguish several regimes of high-energy particle acceleration: while the inner part of the jet is dominated by knots and has properties consistent with local particle acceleration at shocks, the particle acceleration in the outer 3.4 kpc of the jet is likely to be dominated by an unknown distributed acceleration mechanism. In addition to several compact counterjet features we detect probable extended emission from a counterjet out to 2.0 kpc from the nucleus, and argue that this implies that the diffuse acceleration process operates in the counterjet as well. A preliminary search for X-ray variability finds no jet knots with dramatic flux density variations, unlike the situation seen in M87.

description: Século de Humilhação Nacional é um quadro narrativo utilizado por alguns estudiosos e políticos chineses para descrever a história da China desde meados do século XIX até meados do século XX. Apesar de ser uma história inesquecível, o conceito de um Século de Humilhação Nacional tornou-se um termo amplamente utilizado para representar a ideia central do patriotismo na China, com o intuito de que as pessoas tomassem a história como uma alerta. Esse trabalho visa a apresentar o conteúdo do Século de Humilhação e descobrir a sua influência na ascensão do Nacionalismo Chinês e, consequentemente, na construção da identidade nacional da China. A importância da educação da humilhação nacional para povo chinês na construção da identidade nacional é também confirmada nesse trabalho. No entanto, precisamos fazer uma boa distinção entre nacionalismo e patriotismo extremo para não amplificar os problemas existentes, tais como o sentimento anti-japonês chinês, o sentimento anti-ocidental chinês e surgimento dos nacionalistas radicais chineses.

description: The high-synchrotron-peaked blazar VER J0521+211 was discovered in 2009 by VERITAS and is located at an unknown distance. In February 2020, the VERITAS collaboration alerted the multi-messenger community of an ongoing flare from the source, followed by a multi-frequency monitoring campaign led by MAGIC, covering energies from radio to very-high-energy (VHE, E>100GeV) which allowed to observe the source in VHE for 6 consecutive nights. Out of these observations, a statistical upper limit to the source redshift at z<0.243 was set using Fermi-LAT and MAGIC data, a value consistent with lower limits derived from optical spectroscopy. The modeling of the broadband spectral energy distribution (SED) and its night-wise evolution is also presented using two types of models: i) a leptonic two-zone synchrotron-self-Compton scenario; ii) a lepto-hadronic one-zone scenario. Both scenarios allow to reproduce the observed SEDs and their night-wise evolution, and have implications on optical polarization and production of neutrinos. For the first scenario, optical polarimetry measurements were compared with the predictions from the evolution of the two-zones. For the second scenario, limits on the production of neutrinos and enhanced photon emission at ultra-high-energies (E>100TeV) from π⁰ decay were computed.

description: An effective autonomous robot performing dangerous or menial tasks will need to act under significant time and energy constraints. At task time, the amount of effort a robot spends planning its motion directly detracts from its total performance. Manipulation tasks, however, present challenges to efficient motion planning. Tightly coupled steps (e.g. choices of object grasps or placements) allow poor early decisions to render subsequent steps difficult, which this encourages longer planning horizons. However, an articulated robot situated within a geometrically complex and dynamic environment induces a high-dimensional configuration space in which it is expensive to test for valid paths. And since multi-step plans require paths in changing valid subsets of configuration space, it is difficult to reuse computation across steps. This thesis proposes an approach to motion planning well-suited to articulated robots performing recurring multi-step manipulation tasks in complex, semi-structured environments. The high cost of edge validation in roadmap methods motivates us to study a lazy approach to pathfinding on graphs which decouples constructing and searching the graph from validating its edges. This decoupling raises two immediate questions which we address: (a) how to allocate precious validation computation among the unevaluated edges on the graph, and (b) how to efficiently solve the resulting dynamic pathfinding problem which arises as edges are validated. We next consider the inherent tradeoff between planning and execution cost, and show that an objective based on utility functions is able to effectively balance these competing goals during lazy pathfinding. Lastly, we define the family motion planning problem which captures the structure of multi-step manipulation tasks, and propose a related utility function which allows our motion planner to quickly find efficient solutions for such tasks. We assemble our algorithms into an integrated manipulation planning system, and demonstrate its effectiveness on motion and manipulation tasks on several robotic platforms. We also provide open-source implementations of our algorithms for contemporary motion planning frameworks. While the motivation for this thesis originally derived from manipulation, our pathfinding algorithms are broadly applicable to problem domains in which edge validation is expensive. Furthermore, the underlying similarity between lazy and dynamic settings also renders our incremental algorithms applicable to conventional dynamic problems such as traffic routing.

description: Measurement-device-independent quantum key distribution protocol, whose security analysis does not rely on any assumption on the detection system, can immune the attacking against detectors. We give a first composable security analysis for continuous-variable measurement-device-independent quantum key distribution using squeezed states against general coherent attacks. The security analysis is derived based on the entanglement-based scheme considering finite size effect. A version of entropic uncertainty relation is exploited to give a lower bound on the conditional smooth min-entropy by trusting Alice's and Bob's devices. The simulation results indicate that, in the universal composable security framework, the protocol can tolerate 2.5 dB and 6.5 dB channel loss against coherent attacks with direct and reverse reconciliation, respectively.

description: (Draft 3) A generalized differential operator on the real line is defined by means of a limiting process. These generalized derivatives include, as a special case, the classical derivative and current studies of fractional differential operators. All such operators satisfy properties such as the sum, product/quotient rules, chain rule, etc. We study a Sturm-Liouville eigenvalue problem with generalized derivatives and show that the general case is actually a consequence of standard Sturm-Liouville Theory. As an application of the developments herein we find the general solution of a generalized harmonic oscillator. We also consider the classical problem of a planar motion under a central force and show that the general solution of this problem is still generically an ellipse, and that this result is true independently of the choice of the generalized derivatives being used modulo a time shift. The previous result on the generic nature of phase plane orbits is extended to the classical gravitational n-body problem of Newton to show that the global nature of these orbits is independent of the choice of the generalized derivatives being used in defining the force law (modulo a time shift). Finally, restricting the generalized derivatives to a special class of fractional derivatives, we consider the question of motion under gravity with and without resistance and arrive at a new notion of time that depends on the fractional parameter. The results herein are meant to clarify and extend many known results in the literature and intended to show the limitations and use of generalized derivatives and corresponding fractional derivatives.

Elliptic flow of charm and strange hadrons in high-multiplicity pPb collisions at $\sqrt{s_{_\mathrm{NN}}} =$ 8.16 TeV

description: The elliptic azimuthal anisotropy coefficient ($v_2$) is measured for charm (D$^0$) and strange (K$_\mathrm{S}^0$, $Λ$, $Ξ^-$, and $Ω^-$) hadrons, using a data sample of pPb collisions collected by the CMS experiment, at a nucleon-nucleon center-of-mass energy $\sqrt{s_{_\mathrm{NN}}} =$ 8.16 TeV. A significant positive $v_2$ signal from long-range azimuthal correlations is observed for all particle species in high-multiplicity pPb collisions. The measurement represents the first observation of possible long-range collectivity for open heavy flavor hadrons in small systems. The results suggest that charm quarks have a smaller $v_2$ than the lighter quarks, probably reflecting a weaker collective behavior. This effect is not seen in the larger PbPb collision system at $\sqrt{s_{_\mathrm{NN}}} =$ 5.02 TeV, also presented.

description: A temática em destaque é abordada por três pares de estudantes do Curso de Mestrado em Pedagogia e Didáctica (MPD), concentrando-se nas preocupações que, nos últimos tempos, agitam o ambiente escolar. O primeiro objectiva trazer a relação entre a saúde pública e a saúde escolar, no âmbito da pandemia de Covid-19, como elemento necessário para o garante do bom ambiente de aprendizagem e do sucesso pedagógico, realçando que a intenção da educação em criar condições de saúde escolar é firmar a necessidade de que os alunos devem construir conhecimentos sobre a mesma. O segundo, partindo da ideia de que a crise imposta pela pandemia constitui uma ameaça global, sustentado numa pesquisa bibliográfica, apresenta as principais medidas tomadas pelas escolas, de modo a conter a propagação da pandemia, bem como a racionalidade das estratégias adoptadas, para a continuidade das aulas durante o fecho e após a retoma presencial. O terceiro par reflecte sobre o efeito da situação vivenciada actualmente, no ensino formal em Moçambique, almejando uma educação escolar imbuída de novos rumos, tendo por base uma reflexão sobre certas mudanças actuais, decorrentes do quadro global complexo. Considerando que a sustentabilidade para o plano de retoma das aulas presenciais exige a melhoria das condições de higiene nas escolas e de outras medidas de segurança comunitária, a essência do sentimento social é posta em destaque. Face aos contributos dos estudantes, dois professores do MPD centram-se nos desafios lançados pela pandemia Covid-19 à Educação, nomeadamente, no que concerne a ambientes de aprendizagem que possam dar respostas às dificuldades encontradas e à importância da mediação a ser mantida pelos professores, no novo enfoque com que o processo ensino-aprendizagem se depara.

description: We compute the full classical 4d scalar potential of type IIA Calabi-Yau orientifolds in the presence of fluxes and D6-branes. We show that it can be written as a bilinear form $V = Z^{AB} ρ_Aρ_B$, where the $ρ_A$ are in one-to-one correspondence with the 4-form fluxes of the 4d effective theory. The $ρ_A$ only depend on the internal fluxes, the axions and the topological data of the compactification, and are fully determined by the Freed-Witten anomalies of branes that appear as 4d string defects. The quadratic form $Z^{AB}$ only depends on the saxionic partners of these axions. In general, the $ρ_A$ can be seen as the basic invariants under the discrete shift symmetries of the 4d effective theory, and therefore the building blocks of any flux-dependent quantity. All these polynomials may be obtained by derivation from one of them, associated to a universal 4-form. The standard N=1 supergravity flux superpotential is uniquely determined from this {\it master polynomial}, and vice versa.

Competitive IgG Adsorption on Protein A Chromatography Resins and Improving Resin Performance with PEGylated Ligands

description: Protein A (ProA) chromatography is a bioseparations technique employed throughout the biopharmaceutical industry for the selective capture and purification of IgG-class monoclonal antibodies (mAbs) and Fc-fusion proteins. The rapid growth of mAbs as commercial therapeutics has motivated the need for improved, efficient, and high-throughput purification processes during manufacturing. In direct response, the work presented in thesis aims to 1) increase the scientific community’s understanding of IgG adsorption behavior on ProA chromatography resins and 2) improve the performance of ProA chromatography with ligands that are chemically modified using polyethylene glycol (PEGylated). The results of this thesis suggest that IgG molecules of varying binding strength, or varying elution pH, are capable of competing for binding sites on ProA chromatography resins in simultaneous or sequential adsorption. The competitive phenomenon derives from variance in IgG binding strength, or IgG elution pH, due to differences in sub-class behavior as well as secondary IgG binding interactions with the ProA ligand. Competition is readily apparent in the adsorption of human polyclonal IgG, which has a wide variety of IgG sub-classes and binding epitopes. Additionally, the results presented in this thesis suggest that ProA chromatography resins with PEGylated ligands are a viable path to increase resin robustness and real-world chromatographic selectivity. It is demonstrated that ligand PEGylation can increase resistance to proteolytic digestion, mitigate impurity interactions with mAbs that are bound to ProA, and increase process selectivity against Chinese Hamster Ovary host cell proteins by up to 37%. However, resins with large volumes of conjugated PEG significantly decrease IgG static binding capacity and decrease the available pore space for diffusion, resulting in losses in dynamic binding capacity and productivity. Lighter modifications appear to avoid losses in dynamic binding capacity, however, they do not appear to be effective at mitigating impurity interactions with mAbs that are bound to ProA, which is key to increasing process selectivity. PEGylation of ProA also universally increases the elution pH of IgG molecules by weakening the binding interaction. This last result opens another path of viability for PEGylated ProA ligands for purification of mAbs of Fc-fusion proteins that are sensitive to low pH environments.

description: This article presents a study of the evolution of the internal structure and seismic properties expected for low/intermediate mass Pre-Main Sequence (PMS) stars. Seismic and non-seismic properties of PMS stars were analysed. This was done using 0.8 to 4.4M$_\odot$ stellar models at stages ranging from the end of the Hayashi track up to the Zero-Age Main-Sequence (ZAMS). This research concludes that, for intermediate-mass stars (M$>$1.3M$_\odot$), diagrams comparing the effective temperature ($T_{eff}$) against the small separation can provide an alternative to Christensen-Dalsgaard (C-D) diagrams. The impact of the metal abundance of intermediate mass stars (2.5-4.4M$_\odot$) has over their seismic properties is also evaluated.

description: The instrumentation for gamma-ray astronomy has advanced tremendously during the last two decades. The study of the most violent environments in the Universe has opened a new window to understand the frontier of physics, exploring processes that are beyond the capabilities of Earth- based laboratories to replicate. One of the instruments at the forefront of gamma-ray astronomy is the MAGIC stereoscopic system, which consists of two 17-m diameter mirror dish telescopes located at 2200m a.s.l. on the Canary Island of La Palma, in Spain. The year 2023 marks the 20th anniversary of MAGIC, reaching the milestone of 200 publications in peer-reviewed journals over a wide range of research areas, covering astrophysics with Galactic and extragalactic objects, dark matter searches, and cosmology. MAGIC has established itself as a world-wide leading instrument for gamma-ray astronomy in the energy range from 20 GeV to beyond 100 TeV. MAGIC is an active participant in multiple multiwavelength and multimessenger observational campaigns, contributing to our understanding of the universe. In the conference, I will provide a status report of MAGIC, including the discussion of a few outstanding results during the last two decades and the prospects for the near future.

description: Since the completion of genome sequences of model organisms, functional identification of unknown genes has become a principal challenge in biology. Postgenomics sciences such as transcriptomics, proteomics, and metabolomics are expected to discover gene functions. This report outlines the elucidation of gene-to-gene and metabolite-to-gene networks via integration of metabolomics with transcriptomics and presents a strategy for the identification of novel gene functions. Metabolomics and transcriptomics data of Arabidopsis grown under sulfur deficiency were combined and analyzed by batch-learning self-organizing mapping. A group of metabolites/genes regulated by the same mechanism clustered together. The metabolism of glucosinolates was shown to be coordinately regulated. Three uncharacterized putative sulfotransferase genes clustering together with known glucosinolate biosynthesis genes were candidates for involvement in biosynthesis. In vitro enzymatic assays of the recombinant gene products confirmed their functions as desulfoglucosinolate sulfotransferases. Several genes involved in sulfur assimilation clustered with O-acetylserine, which is considered a positive regulator of these genes. The genes involved in anthocyanin biosynthesis clustered with the gene encoding a transcriptional factor that up-regulates specifically anthocyanin biosynthesis genes. These results suggested that regulatory metabolites and transcriptional factor genes can be identified by this approach, based on the assumption that they cluster with the downstream genes they regulate. This strategy is applicable not only to plant but also to other organisms for functional elucidation of unknown genes. © 2005 by The American Society for Biochemistry and Molecular Biology, Inc.

description: Photometric and spectroscopic observations of the Carina dSph revealed that this galaxy contains two dominant stellar populations of different age and kinematics. The co-existence of multiple populations provides new constraints on the dark halo structure of the galaxy, because different populations should be in equilibrium in the same dark matter potential well. We develop non-spherical dynamical models including such multiple stellar components and attempt to constrain the properties of the non-spherical dark halo of Carina. We find that Carina probably has a larger and denser dark halo than found in previous works and a less cuspy inner dark matter density profile, even though the uncertainties of dark halo parameters are still large due to small volume of data sample. Using our fitting results, we evaluate astrophysical factors for dark matter annihilation and decay and find that Carina should be one of the most promising detectable targets among classical dSph galaxies. We also calculate stellar velocity anisotropy profiles for both stellar populations and find that they are both radially anisotropic in the inner regions, while in the outer regions the older population becomes more tangentially biased than the intermediate one. This is consistent with the anisotropy predicted from tidal effects on the dynamical structure of a satellite galaxy and thereby can be considered as kinematic evidence for the tidal evolution of Carina.

Sea: Zone of Proscription and Confinement of Evils

description: The sea is present in the collection of Popular Medicine collected by Michel Giacometti and published in Artes de Cura e Espanta-Males (2009). In many of the recipes and incantations belonging to various medical specialties, the sea – like the mountain or the high pine forest – is an area where evils are thrown / exorcised. From a close reading of the most explicit part of the collection regarding the relationship between the therapeutic ritual and the sea, we find that there is a clear border between humanized spaces – symptomatically, where roosters and chickens are singing and, by extension, other domesticated animals – and the so-called outlawed, non-humanized zones. Necessarily, a boundary to be veiled and maintained for the benefit of (fragile) human and non-human bodies. The person who throws the material remains of a therapeutic ritual into the sea often does so with his back to the sea. The evils are sent to the curdled, salty, sacred sea, or to the very bottom of the sea. Precisely, where they are believed to be no longer harmful and can never return. It is well known that in terms of a landscape history, the sea – as well as the mountain and the desert – was / is, because it is an area of incalculable risk and danger, a hostile landscape. And, only in modern times, the sea (as well as the seaside and the beach) is a landscape and a place of leisure. The aforementioned collection of folk medicine is a testament to this premodern mentality.

description: V.I. Arnold [Russian Math. Surveys, 26 (no. 2), 1971, pp. 29-43] gave a miniversal deformation of matrices of linear operators; that is, a simple canonical form, to which not only a given square matrix A, but also the family of all matrices close to A, can be reduced by similarity transformations smoothly depending on the entries of matrices. We study miniversal deformations of quiver representations and obtain a miniversal deformation of matrices of chains of linear mappings.

description: State-of-the-art integral field surveys like $\mathrm{ATLAS^{3D}}$, SLUGGS, CALIFA, SAMI, and MaNGA provide large data sets of kinematical observations of early-type galaxies (ETGs), yielding constraints on the formation of ETGs. Using the cosmological hydrodynamical \textit{Magneticum Pathfinder} simulations, we investigate the paradigm of fast and slow rotating ETGs in a fully cosmological context. We show that the ETGs within the \textit{Magneticum} simulation are in remarkable agreement with the observations, revealing fast and slow rotators quantified by the angular momentum proxy $λ_{\mathrm{R}}$ and the flattening $ε$ with the observed prevalence. Taking full advantage of the three-dimensional data, we demonstrate that the dichotomy between fast and slow rotating galaxies gets enhanced, showing an upper and lower population separated by an underpopulated region in the edge-on $λ_{\mathrm{R}}$-$ε$ plane. Following the evolution of the $λ_{\mathrm{R}}$-$ε$ plane through cosmic time, we find that, while the upper population is already in place at $z=2$, the lower population gets statistically significant below $z=1$ with a gradual increase. At least $50\%$ of the galaxies transition from fast to slow rotators on a short timescale, in most cases associated to a significant merger event. Furthermore, we connect the $M_{*}$-$j_{*}$ plane, quantified by the $b$-value, with the $λ_{\mathrm{R}}$-$ε$ plane, revealing a strong correlation between the position of a galaxy in the $λ_{\mathrm{R}}$-$ε$ plane and the $b$-value. Going one step further, we classify our sample based on features in their velocity map, finding all five common kinematic groups, also including the recently observed group of prolate rotators, populating distinct regions in the $λ_{\mathrm{R}}$-$b$ plane.

description: The status of the present precision measurements of electroweak observables is reviewed with specific reference to the radiative parameters $S,T,U$ or equivalently $ε_1,ε_2,ε_3$. The significance of the obliqueness hypothesis is underlined and the importance of the ``local fit'' method of extracting these parameters from the data is emphasized. Possible new physics implications are briefly touched upon.

description: In der Zeit zwischen 1907 und 1914 entsandte der Frauenbund der Deutschen Kolonialgesellschaft (FB) in Kooperation mit der Deutschen Kolonialgesellschaft (DKG) mehrere hundert deutsche weiße Frauen als Dienstmädchen in die deutschen Kolonien. Damit stellen die beiden Organisationen zwei zentrale nichtstaatliche Akteur*innen im deutschen kolonialen Migrations- und Genderregime dar, was die These nahelegt, dass die DKG und der FB bedeutenden Einfluss auf die Bedingungen nahmen, unter denen weibliche Migration in die deutschen Kolonien zu dieser Zeit stattfand. Mit Hilfe der Historischen Diskursanalyse wird in diesem Working Paper untersucht, welche Bedeutungen von Migration zwischen der DKG und dem FB bei der Entsendung deutscher weißer Frauen ausgehandelt wurden. Als Grundlage der Analyse werden Protokolle, Schriftverkehr, Verträge sowie weitere Quellen der am Beziehungsdreieck DKG – FB – Migrantinnen beteiligten Akteur*innen herangezogen. Dadurch werden die vergeschlechtlichten Praktiken und Machtgefüge innerhalb der Institutionen, aber auch zwischen den Institutionen und den Migrantinnen sichtbar. Die Arbeit unterliegt dabei einer postkolonialen, feministischen Kritischen Weißseins-Perspektive.
