description: As the world’s largest payments for ecosystem services (PES) program, China’s Sloping Land Conversion Program (SLCP) is designed to combat soil erosion and land degradation by converting cropland on steep slopes into forests. Operating through an incentive-based approach, the SLCP involved 32 million rural households as core agents. This paper aims to fill a research gap regarding how socioeconomic and institutional conditions influence rural households to reach the primary environmental goals. Using fuzzy-set qualitative comparative analysis (fsQCA), we conclude that at the household level, the different pathways to environmental success or failure have been shaped by socioeconomic and institutional conditions in a combinatory manner rather than single conditions alone. Specifically, the combination of household involvement and effective monitoring plays a fundamental role in capacity-building between government and households. We found that financial incentives have a trade-off effect, as they could not only create a positive interaction but also trigger failure in situations with different conditions. Finally, the potential and limits of QCA were discussed, and we call for a more serious reflection on the added value of QCA as an alternative or complementary method to conventional approaches in environmental governance research.

description: We develop a method to estimate the power spectrum of a stochastic process on the sphere from data of limited geographical coverage. Our approach can be interpreted either as estimating the global power spectrum of a stationary process when only a portion of the data are available for analysis, or estimating the power spectrum from local data under the assumption that the data are locally stationary in a specified region. Restricting a global function to a spatial subdomain -- whether by necessity or by design -- is a windowing operation, and an equation like a convolution in the spectral domain relates the expected value of the windowed power spectrum to the underlying global power spectrum and the known power spectrum of the localization window. The best windows for the purpose of localized spectral analysis have their energy concentrated in the region of interest while possessing the smallest effective bandwidth as possible. Solving an optimization problem in the sense of Slepian (1960) yields a family of orthogonal windows of diminishing spatiospectral localization, the best concentrated of which we propose to use to form a weighted multitaper spectrum estimate in the sense of Thomson (1982). Such an estimate is both more representative of the target region and reduces the estimation variance when compared to estimates formed by any single bandlimited window. We describe how the weights applied to the individual spectral estimates in forming the multitaper estimate can be chosen such that the variance of the estimate is minimized.

description: Piled rafts have been used as a foundation system for high-rise buildings worldwide in different soil conditions, e.g., in soft to stiff clay as well as in medium-to-dense sand. Piled raft is currently used not only to control the foundation settlement but also to minimize the required raft thickness to reach the most optimized foundation design. The purpose of this study is to investigate the behavior of piled raft as a foundation system for Frankfurt over-consolidated clay based on the well-monitored Messeturm building in Germany. The numerical tool used in analysis is Plaxis 3D finite element software with hardening soil material model. The piled raft foundation behavior will be evaluated based on the total settlement, differential settlement and the pile skin friction. Based on this study, it was found that the chosen foundation system “plied raft foundation” for Messeturm was an optimized solution for the proposed building.

description: Cosmic strings are predicted in many models beyond the Standard Model of particle physics. In models which admit strings, a network of strings will inevitably be formed in a phase transition in the early universe and will persist to the present time. Strings leave behind distinctive features in cosmology. Searching for these signatures in new observational windows provides a way to constrain particle physics at the high energy scale and is thus complementary to searches for new physics at the low energy end, for example at the LHC. Specifically, I will discuss signatures of cosmic strings in cosmic microwave background polarization maps and in 21cm redshift surveys.

description: The continuously increasing output of published research makes the work of researchers harder as it becomes impossible to keep track of and compare the most recent advances in a field. Scientific knowledge graphs have been proposed as a solution to structure the content of research publications in a machine-readable way and enable more efficient, computer-assisted workflows for many research activities. Crowdsourcing approaches are used frequently to build and maintain such scientific knowledge graphs. Researchers are motivated to contribute to these crowdsourcing efforts as they want their work to be included in the knowledge graphs and benefit from applications built on top of them. To contribute to scientific knowledge graphs, researchers need simple and easy-to-use solutions to generate new knowledge graph elements and establish the practice of semantic representations in scientific communication. In this thesis, I present SciKGTeX, a LATEX package to semantically annotate scientific contributions at the time of document creation. The LATEX package allows authors of scientific publications to mark the main contributions such as the background, research problem, method, results and conclusion of their work directly in LATEX source files. The package then automatically embeds them as metadata into the generated PDF document. In addition to the package, I document a user evaluation with 26 participants which I conducted to assess the usability and feasibility of the solution. The analysis of the evaluation results shows that SciKGTeX is highly usable with a score of 79 out of 100 on the System Usability Scale. Furthermore, the study showed that the functionalities of the package can be picked up very quickly by the study participants which only needed 7 minutes on average to annotate the main contributions on a sample abstract of a published paper. SciKGTeX demonstrates a new way to generate structured metadata for the key contributions of research publications and embed them into PDF files at the time of document creation.

description: We use anticommuting variables to study probability distributions of random variables, that are solutions of Langevin's equation. We show that the probability density always enjoys "worldpoint supersymmetry". The partition function, however, may not. We find that the domain of integration can acquire a boundary, that implies that the auxiliary field has a non-zero expectation value, signalling spontaneous supersymmetry breaking. This is due to the presence of "fermionic" zeromodes, whose contribution cannot be cancelled by a surface term. This we prove by an explicit calculation of the regularized partition function, as well as by computing the moments of the auxiliary field and checking whether they satisfy the identities implied by Wick's theorem. Nevertheless, supersymmetry manifests itself in the identities that are satisfied by the moments of the scalar, whose expressions we can calculate,for all values of the coupling constant. We also provide some quantitative estimates concerning the visibility of supersymmetry breaking effects in the identities for the moments and remark that the shape of the distribution of the auxiliary field can influence quite strongly how easy it would be to mask them, since the expectation value of the auxiliary field doesn't coincide with its typical value.

description: Learners’ academic self-concepts and attributions have been widely evidenced to substantially regulate their educational development. Develop-mentally, they will not only operate in a mutually reinforcing manner. Rather, self-concepts will directly affect learners’ outcome attributions in a particular academic setting. Current research in the English as a foreign language (EFL) context has increasingly analyzed learners’ attributions and self-concepts on a task-specific construct level. Nevertheless, there still exist certain research gaps in the field, particularly concerning learners’ grammar self-concept and attributions. Therefore, the present study aimed at analyzing longitudinal relations of prior performance and self-concept with subsequent attributions of grammar success and failure in a sample of preadolescent EFL learners. Findings demonstrated that attributional patterns mostly but not entirely depended on learners’ grammar self-concept. Poor performing learners holding a low self-concept displayed a maladaptive attribution pattern for explaining both grammar success and failure. Though not with respect to all causal factors, these findings largely confirm the crucial role of task-specific self-concept in longitudinally explaining related control beliefs in the EFL context.
A spatiospectral localization approach to estimating potential fields on the surface of a sphere from noisy, incomplete data taken at satellite altitudes

description: Satellites mapping the spatial variations of the gravitational or magnetic fields of the Earth or other planets ideally fly on polar orbits, uniformly covering the entire globe. Thus, potential fields on the sphere are usually expressed in spherical harmonics, basis functions with global support. For various reasons, however, inclined orbits are favorable. These leave a "polar gap": an antipodal pair of axisymmetric polar caps without any data coverage, typically smaller than 10 degrees in diameter for terrestrial gravitational problems, but 20 degrees or more in some planetary magnetic configurations. The estimation of spherical harmonic field coefficients from an incompletely sampled sphere is prone to error, since the spherical harmonics are not orthogonal over the partial domain of the cut sphere. Although approaches based on wavelets have gained in popularity in the last decade, we present a method for localized spherical analysis that is firmly rooted in spherical harmonics. We construct a basis of bandlimited spherical functions that have the majority of their energy concentrated in a subdomain of the unit sphere by solving Slepian's (1960) concentration problem in spherical geometry, and use them for the geodetic problem at hand. Most of this work has been published by us elsewhere. Here, we highlight the connection of the "spherical Slepian basis" to wavelets by showing their asymptotic self-similarity, and focus on the computational considerations of calculating concentrated basis functions on irregularly shaped domains.

description: In this work, we investigated the optical response of a self-written waveguide (SWW) in detail by heating the structure from room temperature up to 60 °C. Previous results indicated a decrease in the optical transmission with increasing temperature for certain waveguide parameters. Based on new experimental measurements, we have identified material parameters resulting in opposite behaviour. An experimental setup was conceived to verify these results. Hereby, we were able to show that we can adjust material parameters such as refractive index and the corresponding density of the material by adapting the curing time applied during the fabrication of the waveguides. This, in turn, affects the material’s response during the heating process. We showed that a limitation of the external curing time changes the internal conditions of the SWW and the cladding in a manner that the numerical aperture increases with the temperature, which subsequently also results in an increase in the optical transmission. In this study, we explain this unexpected behavior of the SWW and point towards possible future applications. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

description: Искусственный интеллект имитирует человеческий разум в решении конкретных узкоспециализированных задач. Сегодня в области прикладного искусственного интеллекта достигнуты огромные результаты: распознавание лиц, общение на естественном языке, поиск информации и т.п. Направление искусственного интеллекта, связанное с обучением на примерах, называется машинным обучением (англ. machine learning). Но машина не учится, как человек. Ей необходимо задавать модели и алгоритмы. В книге рассматриваются подготовка исходных данных и реализация основных алгоритмов классического машинного обучения, включая несложные нейронные сети, на языке Python. Работа ведётся с использованием инструмента Jupyter Notebook, фактически ставшего стандартом в машинном обучении, и одной из наиболее популярных библиотек машинного обучения — Scikit-Learn. Книга будет полезна как в качестве практико-ориентированного издания для начинающих изучать машинное обучение, так и в качестве справочника для подготовленных читателей.

description: Zur Bereitstellung eines einheitlichen integrierten Raumbezugs ist das Aktualitätsgebot der Festpunktfelder ein wesentliches Qualitätsmerkmal. Vorhandene Veränderungen der Erdoberfläche bewirken eine stetige Verringerung der Aktualität des amtlichen Raumbezugs, da sich die aktuell gemessenen und berechneten Koordinaten von den im Nachweis geführten Koordinaten zunehmend unterscheiden. Zur genauen Abgrenzung der Einflussbereiche von Bodenbewegungen werden daher alle verfügbaren Daten des LGLN für den Aufbau eines niedersächsischen Bodenbewegungsdienstes aufbereitet und auf Veränderungen der Lage- und Höhenkomponenten analysiert. Eine weitere wichtige Säule zum Aufbau dieses Dienstes bilden PSI-Analysen, da mit dieser Technik der Fernerkundung auch Bewegungen außerhalb der linien- und punktförmigen geodätischen Netze erfasst werden können. Die gesammelten numerischen Bewegungsinformationen werden zunächst gebietsweise zur grafischen Visualisierung unter Verwendung eines erweiterten Kriging-Ansatzes zu einem Bodenbewegungsmodell kombiniert. Auf Grundlage derart geschätzter Bewegungsmodelle können Erhaltungsmaßnahmen sowie Wiederholungsmessungen im amtlichen Bezugsrahmen bedarfsorientiert angepasst und durchgeführt werden, wodurch die Aktualität des Raumbezugs gesteigert wird. Perspektivisch können die modellierten Geschwindigkeiten auch zur Berechnung von zusätzlichen Korrekturdaten des SAPOS-Dienstes HEPS dienen. Mithilfe von bereitgestellten örtlichen und zeitlichen Transformationsparametern könnten lokale Anpassungen der Liegenschaftsvermessungen in Bodenbewegungsgebieten für den Nutzer entfallen.

Zusammenfassung

Ein zentrales Ziel der im Dezember 2002 verabschiedeten Reformen der Arbeitnehmerüberlassung bestand darin, „ein angemessenes Schutzniveau für die Zeitarbeitnehmerinnen und Zeitarbeitnehmer zu gewährleisten“. Bilanziert man die Entwicklungen in den letzten Jahren, spricht vieles dafür, dass dieses Ziel nicht erreicht worden ist.
Im europäischen Vergleich sind Leiharbeitskräfte in Deutschland vor allem bezogen auf die Entlohnung besonders schlecht gestellt. Mehr als zwei Drittel der Leiharbeitskräfte in Deutschland arbeiten für Stundenlöhne unterhalb der Niedriglohnschwelle; der Durchschnittslohn von Leiharbeitskräften beträgt nach Angaben des Statistischen Bundesamtes nur 9,71 € brutto pro Stunde und erreicht damit nur knapp 54% des durchschnittlichen Stundenlohns von „Normalarbeitnehmer/innen“. Da die Einsatzschwerpunkte der Leiharbeit in Deutschland vor allem gewerbliche Branchen mit einem vergleichsweise hohen Lohnniveau betreffen, sind die Lohnunterschiede zwischen Leiharbeitskräften und Stammbeschäftigten der Entleihbetriebe besonders ausgeprägt.
Obwohl Zeitarbeitsunternehmen in Deutschland die vollen Arbeitgeberpflichten übernehmen müssen und einsatzbefristete Arbeitsverträge eher das Ausnahme sein sollen, ist die Stabilität der Beschäftigung überwiegend sehr gering. Auch die erhofften großen Klebe- und Brückeneffekte – d.h. Übergänge in reguläre Beschäftigung bei Entleihunternehmen oder in anderen Branchen – haben sich nicht eingestellt. 
Durch die faktische Aushöhlung des im Gesetz verankerten Equal Pay-Gebotes mittels tariflicher Regelungen und die Aufhebung der zeitlichen Begrenzung betrieblicher Einsätze ist es erleichtert worden, durch den Einsatz von Leiharbeit tarifliche Standards zu unterlaufen. Dies setzt auch die Löhne und Arbeitsbedingungen der Stammbeschäftigten in den Entleihbetrieben unter Druck.    

Die Vorschläge der Oppositionspartien zur Re-Regulierung der Leiharbeit gehen in die richtige Richtung, indem sie auf die Aufhebung von Missständen zielen, die durch die Lockerung der rechtlichen Regelungen überhaupt erst möglich geworden sind. Die an­stehende Umsetzung der EU-Richtlinie in Deutschland bietet die Chance, die Regulierung der Leiharbeit in Deutschland auf den Prüfstand zu stellen und unter Berücksichtigung aktueller (Fehl-)Ent­wicklungen neu zu justieren. Diese Chance sollte genutzt werden, statt nur auszuloten, wie die Anforderungen der Richtlinie mit möglichst wenigen Veränderungen der bisherigen Regulierungspraxis erfüllt werden können.

description: Numerous recent evidences for neutrino masses have established the leptogenesis mechanism as a very natural possible explanation for the baryon asymmetry of the Universe. The explicit realization of this mechanism depends on the neutrino mass model considered. If the right-handed type-I seesaw model of neutrino masses is certainly the most straightforward, it is not the only natural one, especially in the framework of explicit GUT realizations of the seesaw. In this review we discuss in detail the various seesaw scenarios that can implement the leptogenesis mechanism successfully, beyond the paradigm of the pure standard type-I seesaw model. This includes scenarios based on the existence of scalar triplets (type-II), of fermion triplets (type-III) as well as mixed seesaw frameworks.

description: In this paper, a graphics processing unit-accelerated smoothed particle hydrodynamics solver is presented to simulate the three-dimensional explosions in soils and their damage to aluminium structures. To achieve this objective, a number of equations of state and constitutive models required to close the governing equations are incorporated into the proposed smoothed particle hydrodynamics framework, including the Jones-Wilkins-Lee equation of state for explosive materials, the Grüneisen equation of state for metals, the elastic-perfectly plastic constitutive model for metals, and the elastoplastic and elasto-viscoplastic constitutive models for soils. The proposed smoothed particle hydrodynamics methodology was implemented using the Compute Unified Device Architecture programming interface on an NVIDIA graphics processing unit in order to improve the computational efficiency. The various components of the proposed methodology were validated using four test cases, namely, a C4 detonation and an aluminium bar expanded by denotation to validate the modelling of explosion, a cylindrical Taylor bar impact test case to validate the modelling of large deformation in metals, a sand collapse test for the modelling of soils. Following the validation, the proposed method was used to simulate the detonation of an explosive material (C4) in soil and the concomitant deformation of an aluminium plate resulting from this explosion. The predicted results of this simulation are shown to be in good conformance with available experimental data. Finally, it is shown that the proposed graphics processing unit-accelerated SPH solver is able to model interaction problems involving millions of particles in a reasonable time. © 2021 The Authors

description: A Quantum Internet, i.e., a global interconnection of quantum devices, is the long term goal of quantum communications, and has so far been based on two-dimensional systems (qubits). Recent years have seen a significant development of high-dimensional quantum systems (qudits). While qudits present higher photon information efficiency and robustness to noise, their use in quantum networks present experimental challenges due to the impractical resources required in high-dimensional quantum repeaters. Here, we show that such challenges can be met via the use of standard quantum optical resources, such as weak coherent states or weak squeezed states, and linear optics. We report a concrete design and simulations of an entanglement swapping scheme for three and four dimensional systems, showing how the network parameters can be tuned to optimize secret key rates and analysing the enhanced noise robustness at different dimensions. Our work significantly simplifies the implementation of high-dimensional quantum networks, fostering their development with current technology.

description: Crassocephalum crepidioides is an African orphan crop that is used as a leafy vegetable and medicinal plant. Although it is of high regional importance in Sub-Saharan Africa, the plant is still mainly collected from the wild and therefore efforts are made to promote its domestication. However, in addition to beneficial properties, there was first evidence that C. crepidioides can accumulate the highly toxic pyrrolizidine alkaloid (PA) jacobine and here it was investigated, how jacobine production is controlled. Using ecotypes from Africa and Asia that were characterized in terms of their PA profiles, it is shown that the tetraploid C. crepidioides forms jacobine, an ability that its diploid close relative Crassocephalum rubens appears to lack. Evidence is provided that nitrogen (N) deficiency strongly increases jacobine in the leaves of C. crepidioides, that this capacity depends more strongly on the shoot than the root system, and that homospermidine synthase (HSS) activity is not rate-limiting for this reaction. A characterization of HSS gene representation and transcription showed that C. crepidioides and C. rubens possess two functional versions, one of which is conserved, that the HSS transcript is mainly present in roots and that its abundance is not controlled by N deficiency. In summary, this work improves our understanding of how environmental cues impact PA biosynthesis in plants and provides a basis for the development of PA-free C. crepidioides cultivars, which will aid its domestication and safe use. © Copyright © 2021 Schramm, Rozhon, Adedeji-Badmus, Liang, Nayem, Winkelmann and Poppenberger.

Evolutionary constraints on the planetary hypothesis for transition discs

description: We assume a scenario in which transition discs (i.e. discs around young stars that have signatures of cool dust but lack significant near infra-red emission from warm dust) are associated with the presence of planets (or brown dwarfs). These are assumed to filter the dust content of any gas flow within the planetary orbit and produce an inner `opacity hole'. In order to match the properties of transition discs with the largest (~50 A.U. scale) holes, we place such `planets' at large radii in massive discs and then follow the evolution of the tidally coupled disc-planet system, comparing the system's evolution in the plane of mm flux against hole radius with the properties of observed transition discs. We find that, on account of the high disc masses in these systems, all but the most massive `planets' (100 Jupiter masses) are conveyed to small radii by Type II migration without significant fading at millimetre wavelengths. Such behaviour would contradict the observed lack of mm bright transition discs with small (<10 A.U.) holes. On the other hand, imaging surveys clearly rule out the presence of such massive companions in transition discs. We conclude that this is a serious problem for models that seek to explain transition discs in terms of planetary companions unless some mechanism can be found to halt inward migration and/or suppress mm flux production. We suggest that the dynamical effects of substantial accretion on to the planet/through the gap may offer the best prospect for halting such migration but that further long term simulations are required to clarify this issue.

description: GENUS HIGGINSIA HIGGIN, 1877
Diagnosis: See Van Soest (2002).
Type species: Higginsia coralloides Higgin, 1877.
Included species: In WPD, Van Soest et al. (2018) listed 26 species. We have examined the type material of only six of these species. Higginsia durissima (Burton, 1928: p. 131, fig. 2) is returned to Bubaris Gray, 1867, because there is no justification for its transferral to Higginsia; Higginsia anfractuosa Hooper & Lévi, 1993 and Higginsia fragilis Lévi, 1961 are reassigned to Hymedesmiidae.
Remarks: Van Soest (2002) stated that the spined microscleres can be curved and that raphides or trichodragmata may occur. He was referring to Higginsia lunata Carter, 1885. Van Soest & Hooper (2005) subsequently resurrected the genus Desmoxya for this species (see remarks on Desmoxya).

description: The options framework for hierarchical reinforcement learning has increased its popularity in recent years and has made improvements in tackling the scalability problem in reinforcement learning. Yet, most of these recent successes are linked with a proper options initialization or discovery. When an expert is available, the options discovery problem can be addressed by learning an options-type hierarchical policy directly from expert demonstrations. This problem is referred to as hierarchical imitation learning and can be handled as an inference problem in a Hidden Markov Model, which is done via an Expectation-Maximization type algorithm. In this work, we propose a novel online algorithm to perform hierarchical imitation learning in the options framework. Further, we discuss the benefits of such an algorithm and compare it with its batch version in classical reinforcement learning benchmarks. We show that this approach works well in both discrete and continuous environments and, under certain conditions, it outperforms the batch version.
