Selbstberichtete Praktiken von Lehrkräften im inklusiven Mathematikunterricht – Eine Interviewstudie
Authors: Prediger Susanne , Buró Sarah 
Published: August 2020

ZusammenfassungWie Lehrkräfte ihren inklusiven Mathematikunterricht ausgestalten, wird im Modell der gegenstandsbezogenen Expertise dadurch charakterisiert, welche Praktiken sie zur Bewältigung typischer didaktischer Anforderungssituationen nutzen: Lernvoraussetzungen identifizieren und diagnostizieren, differenzieren, fördern und gemeinsames Lernen anregen. Die qualitative Interviewstudie untersucht die selbstberichteten Praktiken der Lehrkräfte bzgl. der zugrundeliegenden inklusionsbezogenen Orientierungen und Wahrnehmungs- und Denkkategorien. Interviewt werden 17 Lehrkräfte, die ihre Praktiken beschreiben und reflektieren, und zwar alle zur gleichen Unterrichtseinheit „Prozente verstehen“ (Klasse 7). Die qualitative Analyse rekonstruiert fünf typische Leitkategorien: soziale Teilhabe, Beschäftigung, Aufgabenbewältigung, inhaltliche Teilhabe und stufengerechte Lernzuwächse, zwischen denen die Lehrkräfte wechseln. Die Analyse zeigt, wie sich diese Leitkategorien in den Praktiken genauer ausprägen.
Ontologies and Data Management: A Brief Survey
Authors: Schneider Thomas , Šimkus Mantas 
Published: August 2020

AbstractInformation systems have to deal with an increasing amount of data that is heterogeneous, unstructured, or incomplete. In order to align and complete data, systems may rely on taxonomies and background knowledge that are provided in the form of an ontology. This survey gives an overview of research work on the use of ontologies for accessing incomplete and/or heterogeneous data.

AbstractFor many coastal areas including the Baltic Sea, ambitious nutrient abatement goals have been set to curb eutrophication, but benefits of such measures were normally not studied in light of anticipated climate change. To project the likely responses of nutrient abatement on eelgrass (Zostera marina), we coupled a species distribution model with a biogeochemical model, obtaining future water turbidity, and a wave model for predicting the future hydrodynamics in the coastal area. Using this, eelgrass distribution was modeled for different combinations of nutrient scenarios and future wind fields. We are the first to demonstrate that while under a business as usual scenario overall eelgrass area will not recover, nutrient reductions that fulfill the Helsinki Commission’s Baltic Sea Action Plan (BSAP) are likely to lead to a substantial areal expansion of eelgrass coverage, primarily at the current distribution’s lower depth limits, thereby overcompensating losses in shallow areas caused by a stormier climate.

AbstractTaB2-SiC coating modified by different content of MoSi2 was fabricated on graphite substrate with SiC inner coating by liquid phase sintering to elevate the anti-oxidation capability of the TaB2-SiC coatings. As compared to the sample with the TaB2—40wt%SiC coating, the coating sample modified with MoSi2 exhibited a weight gain trend at lower temperatures, the fastest weight loss rate went down by 76%, and the relative oxygen permeability value reduced from about 1% to near 0. More importantly, the large amount of SiO2 glass phase produced over the coating during oxidation was in contact with the modification of MoSi2, which was proved to be beneficial to the dispersion of Ta-oxides. A concomitantly formed continuous Ta-Si-O-B compound glass layer showed excellent capacity to prevent oxygen penetration. However, when the TaB2 content was sacrificed to increase the MoSi2 content, the relative oxygen permeability of the coating increased instead of decreased. Thus, on the basis of ample TaB2 content, increasing the MoSi2 content of the coating is conducive to reducing the relative oxygen permeability of the coatings in a broad temperature region.
Black Lives Matter Principles as an Africentric Approach to Improving Black American Health
Authors: Anderson-Carpenter Kaston D. 
Published: August 2020

AbstractAlthough public health has made substantial advances in closing the health disparity gap, Black Americans still experience inequalities and inequities. Several theoretical frameworks have been used to develop public health interventions for Black American health; yet the existing paradigms do not fully account for the ontology, epistemology, or axiology of Black American populations. The Black Lives Matter (BLM) movement provides a basis for understanding the constructs that may contribute to Black American health. By drawing from the 13 BLM principles, this paper presents an alternative approach for developing, implementing, and evaluating public health interventions for Black populations in the USA. Furthermore, the approach may inform future public health research and policies to reduce health disparities within and across Black populations in the USA.
Gyroless Spin-Stabilization Controller and Deorbiting Algorithm for CubeSats
Authors: Morales Jose E. , Kim Jongrae , Richardson Robert R. 
Published: August 2020

AbstractCubeSats are becoming increasingly popular in the scientific community. While they provide a whole new range of opportunities for space exploration, they also come with their own challenges. One of the main concerns is the negative impact which they can have in the space debris problem. Commonly lacking from attitude determination and propulsion capabilities, it has been difficult to provide CubeSats with means for active deorbiting. While electric propulsion technology has been emerging for its application in CubeSats, little or no literature is available on methods to enable it to be used for deorbiting purposes, especially within the tight constraints faced by these nanosatellites. We present a new and simple algorithm for CubeSat deorbiting, which proposes the use of novel electric propulsion technology with minimum sensing and actuation capabilities. The algorithm is divided into two stages: a spin-stabilization control; and a deorbiting-phase detection. The spin-stabilization control is inspired by the B-dot controller. It does not require gyroscopes, but only requires magnetometers and magnetorquers as sensors and actuators, respectively. The deorbiting-phase detection is activated once the satellite is spin-stabilized. The algorithm can be easily implementable as it does not require any attitude information other than the orbital information, e.g., from the Global Positioning System receiver, which could be easily installed in CubeSats. The effectiveness of each part of the algorithms is validated through numerical simulations. The proposed algorithms outperform the existing approaches such as deorbiting sails, inflatable structures, and electrodynamic tethers in terms of deorbiting times. Stability and robustness analysis are also provided. The proposed algorithm is ready to be implemented with minimal effort and provides a robust solution to the space junk mitigation efforts.
Holistic Analysis of Coronavirus Literature: A Scientometric Study of the Global Publications Relevant to SARS-CoV-2 (COVID-19), MERS-CoV (MERS) and SARS-CoV (SARS)
Authors: Şenel Engin , Topal Fatih Esad 
Published: August 2020

ABSTRACTObjectives:In late December 2019, a cluster of patients with pneumonia caused by an unknown pathogen was reported from Wuhan, Hubei Province, China. The pathogen has been identified as a novel coronavirus, severe acute respiratory syndrome 2 (SARS-CoV-2) and the disease has been named as coronavirus disease 2019 (COVID-19). The objective of this study was to perform the first holistic scientometric evaluation of coronavirus publications.Methods:Our main source for this study was Web of Science Collection database. All items published between 1980 and 2019 were included. A distribution map of global production in coronavirus literature and scientometric networks were generated.Results:The United States, China, Germany, the United Kingdom, and Netherlands were the most productive countries. Publications in coronavirus literature have been produced from almost every country in the world, except for some countries in Asia and Africa.Conclusion:While in the 1980s, the United States and developed countries from Europe were major source countries and the virus was identified only as an animal disease in the literature and its biological and genetic structure was investigated, in the 2000s, China became a major contributor of coronavirus literature because the SARS outbreak originated from southern China. Almost all most-cited publications in this period are related to SARS and the ACE2 protein.
Deep Disagreement, Hinge Commitments, and Intellectual Humility
Authors: Johnson Drew 
Published: August 2020

AbstractWhy is it that some instances of disagreement appear to be so intractable? And what is the appropriate way to handle such disagreements, especially concerning matters about which there are important practical and political needs for us to come to a consensus? In this paper, I consider an explanation of the apparent intractability of deep disagreement offered by hinge epistemology. According to this explanation, at least some deep disagreements are rationally unresolvable because they concern ‘hinge’ commitments that are unresponsive to rational considerations. This explanation, if correct, seems to have troubling implications for how we should respond to deep disagreement. If my position on a topic is not responsive to rational considerations, then what choice have I but to dogmatically hold to that position, and simply dismiss the views of those with whom I disagree? I address this problem by identifying an attitude of intellectual humility that is appropriate to have towards one's hinge commitments, and suggest that this attitude provides the basis for a non-rational, constructive way to resolve deep disagreement.
Petrogenesis of a rare Ediacaran tonalite–trondhjemite–granodiorite suite, Egypt, and implications for Neoproterozoic Gondwana assembly
Authors: Abdel-Rahman Abdel-Fattah M 
Published: August 2020

AbstractMost tonalite–trondhjemite–granodiorite (TTG) suites are Archean–Palaeoproterozoic in age, but those of Neoproterozoic–Phanerozoic age are scarce. A rare Ediacaran high-Al TTG suite has been identified at the Fannani Igneous Complex (FIC) in the northern Arabian–Nubian Shield, which is essentially composed of amalgamated Neoproterozoic island-arc Pan-African composite terranes that contain several ophiolitic sutures. The FIC exhibits a wide range of SiO2, Al2O3, Sr and Zr, shows moderate rare earth element (REE) enrichment, and K, Ti, Nb, Y and heavy REE depletion. It is a subsolvus suite with clear orogenic affinities and strong arc-geochemical signatures. The precise U–Pb zircon thermal ionization mass spectrometry age obtained (607.4 ± 1.95 Ma) indicates oceanic subduction extended to late stages of the East African Orogeny. The FIC exhibits87Sr/86Sr compositions of 0.70346–0.71091 (Sr(i)ratio, 0.70284), and143Nd/144Nd of 0.51254–0.51270 (ϵNd(t) = +5.12 to +7.16), typical of modern oceanic-arc rocks (as Japan-arc basalts), and suggestive of mantle sources and island-arc settings. The FIC possesses low values of Yb (1.55 ppm), Nb (14 ppm) and Y (24 ppm), and high ratios of Sr/Y (27), Zr/Sm (46) and Nb/Ta (11.8), typical of magmas produced by anatexis of a basaltic slab. Partial melting models show that the FIC magma was generated by melting (F= 0.25–0.50) of a subducted oceanic crust transformed into eclogite, leaving 10–25% garnet in the residue. The FIC and similar complexes produced via slab melting during the closure of the Mozambique Ocean formed large juvenile belts along the East African Orogen that sutured East and West Gondwana together into a united supercontinent.

AbstractBackgroundThe COVID-19 pandemic has greatly affected public health and wellbeing. In response to the pandemic threat of the coronavirus epidemic, several countries, including China, adopted lockdown and quarantine policies, which may cause psychological distress. This study aimed to explore the psychological impact of province-wide lockdown and personal quarantine during the COVID-19 outbreak in China as well as the corresponding risk factors and protective factors.MethodsWe examined the immediate (2-week) and delayed (2-month) impact of province-wide lockdown and personal quarantine on psychological distress in a national sample of 1390 Chinese residents.ResultsNo immediate impact of province-wide lockdown on psychological distress was observed, whereas personal quarantine increased individuals’ anxiety, fear, and anger. Despite the lack of initial association, psychological distress increased among those in province-wide lockdown. Self-stigma and personal control both significantly moderated the association between lockdown and psychological distress, but in different directions. Those with higher self-stigma and lower personal control were more impacted by the lockdown. Government support moderated the impact of quarantine on psychological distress, but not that of lockdown.ConclusionsThe delayed effects of lockdown and quarantine on psychological distress were observed, and self-stigma, social support, and perceived control moderate the relationships. This study is the first to demonstrate the psychological costs of province-wide lockdowns on individuals’ mental health, providing evidence of the need for mitigation strategies and timely public mental health preparedness in countries with recent outbreaks of COVID-19.
Self-authorizing action: Onlet me Xin English social interaction
Authors: Hoey Elliott M. 
Published: August 2020

AbstractThis article contributes to conversation analytic research on the formatting of imperative actions by focusing on the English first person imperativelet me/lemme Xas it appears in a range of naturally occurring interactions. I argue thatlemme Xis a practice for displacing what was projectably relevant in a given environment in favor of a self-authorized action. This as a result tends to advance the speaker's interests/initiatives. The analysis accounts for speakers’ apparent presumption of permission in unilaterally undertaking theirlemme Xaction by reference to the placement, design, and subsequent orientations to the self-authorized action. The construction is discussed in terms of the distribution of agency and it is suggested thatlemme Xis particularly suited to advancing activities that favor autonomous action by the speaker and which involve the recipient only minimally.

Abstract
Multi-Robot System (MRS) is composed of a group of robots that work cooperatively. However, Multi-Agent System (MAS) is computational systems consisting of a group of agents that interact with each other to solve a problem. The central difference between MRS and MAS is that in the first case, the agent is a robot, and in the second, it is a software. Analyzing the scientific literature, it is possible to notice that few studies address the integration between MAS and MRS. In order to achieve the interdisciplinary integration, the theoretical background of these areas must be considered in this paper, so that the integration can be applied using a case study of decentralized MRS. The objective of this MRS is to track and surround a stationary target. Also, it has been implemented and validated in the robot simulator called Virtual Robot Experimentation Platform (V-REP). In the validation of the proposed MRS, a scenario with three robots and a stationary target were defined. In the tracking task, the robot can detect the target whose position is not known a priori. When the detection occurs, the V-REP informs the target position to the robot because the environment is discretized into a grid of rectangular cells. After that, all the robots are directed to the target, and the surround task is realized. In this task, a mathematical model with direct communication between the robots was used to keep the robots equidistant therefrom and from each other.
Ultra-processed food industry regulation for tackling obesity and diet-related non-communicable diseases in the Brazilian legislature: many proposals, no enactments
Authors: Mariath Aline Brandão , Martins Ana Paula Bortoletto 
Published: August 2020

AbstractObjective:To assess efforts of the Brazilian legislature to regulate ultra-processed food industry practices related to obesity and diet-related non-communicable diseases during the first 4 years of the United Nations’ Decade of Action on Nutrition.Design:We searched the Chamber of Deputies and Federal Senate internal databases to identify bills under consideration between 2016 and December 2019. Keywords related to the main recommendations of international organisations regarding the regulation of food industry practices were used. Descriptive and content analysis of the bills were carried out.Setting:Brazilian legislature (Chamber of Deputies and Federal Senate).Participants:None.Results:Eighty-four bills were identified. The most frequently addressed topics were: nutrition labelling (38·1 %), marketing of unhealthy products (30·9 %), availability of unhealthy products (26·2 %) and critical nutrients content (14·3 %). Only 9·5 % of bills have proposed taxation on unhealthy products. No bill was passed during that period; 2·4 % were rejected and 10·7 % archived. Among the bills still under consideration, 52·4 % have not been passed in any Committee.Conclusions:Although many bills have been introduced, no regulation of ultra-processed food industry practices has been enacted by the Brazilian legislature by 2020. It is likely that no positive impact on population nutrition in Brazil will be achieved by the end of the United Nation’s Decade of Action on Nutrition, in 2025 – especially regarding those goals set by the Brazilian government which were supposed to have been achieved by 2019.
Unknown effects of social innovations
Authors: Zürn Michael 
Published: August 2020

AbstractThe omnipresence of radical uncertainty asks for a concept of causality that moves beyond the notion of predicted probabilities. Protean power is a most important contribution to move International Relations research in this direction. Yet, some of the key components need further grounding in existing concepts and debates. First, protean power should include the notion of directionality in order to be power. Second, it should allow for an analysis of the different forms of relation between protean power and different types of uncertainties. And it should focus on features of the power relationship instead of the context in which it takes place to be able to transfer it to contexts other than uncertainty.
A simple method to simultaneously increase the gain and bandwidth of wearable antennas for application in medical/communications systems
Authors: Khajeh-Khalili Farzad , Shahriari Ali , Haghshenas Fatemeh 
Published: August 2020

AbstractIn this paper, a simple and efficient method to increase the gain and bandwidth of the wearable antennas used in several medical/communications systems is presented. To increase the gain and bandwidth simultaneously, the triple transmission lines (TTLs) method has been used. With this method, the frequency ranges of 1.7–2.5 and 5.4–5.95 GHz are covered with dual-band responses. Also, the simulated maximum gain at 2 and 5.8 GHz is equal to 8.26 and 9.86 dB, respectively. Using the TTLs method, the second frequency band (5.4–5.95 GHz) is achieved. Also, the gain improvement in operating frequencies is more than 4 dB compared to the conventional antenna. The dimensions of the proposed wearable high-gain antenna are 80 × 92 × 2 mm3 or 0.57 × 0.67 × 0.01 λg3 at 2 GHz. Finally, a dual-band sample antenna for use in medical systems was fabricated with a flexible felt substrate and its characteristics were measured. There is a good fit between the measurement and simulation results.
Biomarker Distributions in (Sub)‐Arctic Surface Sediments and Their Potential for Sea Ice Reconstructions

Published: August 2020

AbstractTo evaluate the present sea ice changes in a longer‐term perspective, the knowledge of sea ice variability on preindustrial and geological time scales is essential. For the interpretation of proxy reconstructions it is necessary to understand the recent signals of different sea ice proxies from various regions. We present 260 new sediment surface samples collected in the (sub‐)Arctic Oceans that were analyzed for specific sea ice (IP25) and open‐water phytoplankton biomarkers (brassicasterol, dinosterol, and highly branched isoprenoid [HBI] III). This new biomarker data set was combined with 615 previously published biomarker surface samples into a pan‐Arctic database. The resulting pan‐Arctic biomarker and sea ice index (PIP25) database shows a spatial distribution correlating well with the diverse modern sea ice concentrations. We find correlations of PBIP25, PDIP25, and PIIIIP25 with spring and autumn sea ice concentrations. Similar correlations with modern sea ice concentrations are observed in Baffin Bay. However, the correlations of the PIP25 indices with modern sea ice concentrations differ in Fram Strait from those of the (sub‐)Arctic data set, which is likely caused by region‐specific differences in sea ice variability, nutrient availability, and other environmental conditions. The extended (sea ice) biomarker database strengthens the validity of biomarker sea ice reconstructions in different Arctic regions and shows how different sea ice proxies combined may resolve specific seasonal sea ice conditions.
