description: Background: There is a need for biomarker to identify patients "at risk" for rheumatoid arthritis (risk-RA) and to better predict the therapeutic response and in this study we tested the hypothesis that novel native and citrullinated heterogeneous nuclear ribonucleoprotein (hnRNP)-DL autoantibodies could be possible biomarkers. Methods: Using protein macroarray and ELISA, epitope recognition against hnRNP-DL was analysed in sera from different developed RA disease and diagnosed SLE patients. Toll-like receptor (TLR) 7/9 and myeloid differentiation primary response gene 88 (MyD88)-dependency were studied in sera from murine disease models. HnRNP-DL expression in cultivated cells and synovial tissue was analysed by indirect immunofluorescence, immunoblot and immunohistochemistry. Results: HnRNP-DL was highly expressed in stress granules, citrullinated in the rheumatoid joint and targeted by autoantibodies either as native or citrullinated proteins in patient subsets with different developed RA disease. Structural citrullination dependent epitopes (SCEs) of hnRNP-DL were detected in 58% of the SLE patients although 98% of these sera were alpha-CCP-2-negative. To obtain a specific citrullinated signal value, we subtracted the native antibody value from the citrullinated signal. The citrullinated/native index of autoantibodies against hnRNP-DL (CNDL-Index) was identified as a new value for an "individual window of treatment success" in early RA and for the detection of RF IgM/alpha-CCP-2 seronegative RA patients (24-46%). Negative CNDL-index was found in SLE patients, risk-RA and early RA cohorts such as EIRA where the majority of these patients are DAS28-responders to methotrexate (MTX) treatment (87%). High positive CNDL-values were associated with more severe RA, shared epitope and parenchymal changes in the lung. Specifically, native a-hnRNP-DL is TLR7/9-dependent, associated with pain and ROC analysis revealed an association to initial MTX or etanercept treatment response, especially in seronegative RA patients. Conclusion: CNDL-index defines people at risk to develop RA and the "window of treatment success" thereby closing the sensitivity gap in RA.

Year: 2022

description: Notes from the Underdog" is a project that analyses the extreme forms of agriculture emerging in unclaimed lands of Porto, between 2013 and 2015. The book looks at agricultural practices and the appropriation of space in the city of Porto, Portugal, and the different ways in which this phenomenon has manifested in the aftermath of the financial crisis of 2011. The project recounts the stories of ten gardens and the people running them, who have resuscitated urban brownfield sites by growing fruits and vegetables as a source of food. To achieve this end, they have developed infrastructures like watering and irrigation systems and methods of cultivation, recycling, and composting, while also building storage structures and producing their own tools. Although the gardens are primarily about people providing for themselves, they also lend themselves to recreation and leisure activities.

description: In Erased (2021) Paulo Simão evokes Erased De Kooning Drawing by Robert Rauschenberg and, by manipulating a set of images from the US Library of Congress, reframes the archive and develops a series that invites us to a myriad of questions and reflections. With his intervention Paulo Simão creates a kind of anti-evocative monument and, by isolating the plinth, he opens a new perspective and approach to the artistic work, moreover, emphasizes the importance and role that the artist, the artistic work and, in this particular project, the evocative public art piece assumes by validating certain values, knowledge, historical events or collective memories.

description: In this essay, Mark Durden reflects upon a selection of images of Roy DeCarava presented at an exhibition at David Zwirner gallery in London 13 years after his death. What is remarkable about DeCarava’s work is its multivalency, subtle and nuanced in response to the world around him, avoiding polemical or didactic stances. Aware of the documentary’s association with photographers who would picture Harlem from the outside, DeCarava declared: “I'm not a documentarian, I never have been. I think of myself as poetic, a maker of visions, dreams, and a few nightmares.” In its poetic register, DeCarava’s images possess a symbolic resonance, with implications of segregation and separation, as playing a part in the metaphorical representation of the people captured on his images.

description: Let R be a complete discrete valuation ring, S=R[[u]] and n a positive integer. The aim of this paper is to explain how to compute efficiently usual operations such as sum and intersection of sub-S-modules of S^d. As S is not principal, it is not possible to have a uniform bound on the number of generators of the modules resulting of these operations. We explain how to mitigate this problem, following an idea of Iwasawa, by computing an approximation of the result of these operations up to a quasi-isomorphism. In the course of the analysis of the p-adic and u-adic precisions of the computations, we have to introduce more general coefficient rings that may be interesting for their own sake. Being able to perform linear algebra operations modulo quasi-isomorphism with S-modules has applications in Iwasawa theory and p-adic Hodge theory.

We study a spin model Hamiltonian with short range ferromagnetic interaction competing with an antiferromagnetic component that decays as a power law of the distance between spins, $1/r^α$. These systems may develop a nematic phase between the isotropic disordered and stripe phases. We evaluate the nematic order parameter using a self-consistent mean field calculation. Our main result indicates that the nematic phase exists, at mean-field level, provided $0

description: We propose an extension of the non-homogeneous Gaussian regression (NGR) model by Gneiting et al. (2005) that yields locally calibrated probabilistic forecasts of tem- perature, based on the output of an ensemble prediction system (EPS). Our method represents the mean of the predictive distributions as a sum of short-term averages of local temperatures and EPS-driven terms. For the spatial interpolation of temperature averages and local forecast uncertainty parameters we use a Gaussian random field model with an intrinsically stationary component that captures large scale fluctuations and a location-dependent nugget effect that accounts for small scale variability. Based on the dynamical forecasts by the COSMO-DE-EPS and observational data over Germany we evaluate the performance of our method and and compare it with other post-processing approaches such as geostatistical model averaging. Our method yields locally calibrated and sharp probabilistic forecasts and compares favorably with other approaches. It is reasonably simple, computationally efficient, and therefore suitable for operational usage in the post-processing of temperature ensemble forecasts.

For condensates with $N_v$ vortices, $N_v$ Kelvin-Tkachenko mode branches are obtained. The features of these modes are compared with those predicted by a classical point vortex model. We have created movies to visualize the motion of the vortices corresponding to the Kelvin-Tkachenko waves.

description: Die Corona-Pandemie gilt in vielen Bereichen als Antreiber der Digitalisierung, so auch in der Lehrkräftebildung. Durch Schulschließungen und Betretungsverbote externer Personen konnten diverse Praktika innerhalb des Studiums der angehenden Lehrpersonen nicht umgesetzt werden. Hiermit entfallen für viele Lehramtsstudierende Gelegenheiten, Lernfortschritte aber auch Leistungsprobleme von Kindern zu erkennen und mögliche Hilfen zu reflektieren. Aufgabe als zukünftige Lehrperson ist es jedoch, im Unterricht zu erkennen, „wo sich der einzelne Lernende in seinem Lernprozess befindet und welche Hilfen und Rückmeldungen dieser benötigt“ (Praetorius et al., 2012, S. 137). Diagnosen allein sind dabei aber nicht ausreichend, um den Lernprozess positiv zu beeinflussen. Es bedarf weiterer Schritte bzw. gezielter Interventionen der Lehrkraft. Brühwiler (2014, S. 14) schreibt daran anschließend, dass „eine hohe diagnostische Kompetenz nur gekoppelt mit didaktischen Maßnahmen lernwirksam“ wird. Lehrpersonen sollten frühzeitig und damit idealerweise bereits im Studium auf die Aufgabe der Diagnose des Lernstands und der Ableitung daran anschließender Maßnahmen vorbereitet werden, da im Studium auch eine Verzahnung mit dem fachdidaktischen Wissen möglich ist. An der Universität Erfurt werden im Rahmen des Projekts DIAMOS Videovignetten mit der Zielstellung eingesetzt, die diagnostischen Fähigkeiten von Lehramtsstudierenden zu stärken, gerade auch durch fehlende Möglichkeiten echter Praxiserfahrungen während der Pandemie.

description: Average Hausdorff distance is a widely used performance measure to calculate the distance between two point sets. In medical image segmentation, it is used to compare ground truth images with segmentations allowing their ranking. We identified, however, ranking errors of average Hausdorff distance making it less suitable for applications in segmentation performance assessment. To mitigate this error, we present a modified calculation of this performance measure that we have coined "balanced average Hausdorff distance". To simulate segmentations for ranking, we manually created non-overlapping segmentation errors common in magnetic resonance angiography cerebral vessel segmentation as our use-case. Adding the created errors consecutively and randomly to the ground truth, we created sets of simulated segmentations with increasing number of errors. Each set of simulated segmentations was ranked using both performance measures. We calculated the Kendall rank correlation coefficient between the segmentation ranking and the number of errors in each simulated segmentation. The rankings produced by balanced average Hausdorff distance had a significantly higher median correlation (1.00) than those by average Hausdorff distance (0.89). In 200 total rankings, the former misranked 52 whilst the latter misranked 179 segmentations. Balanced average Hausdorff distance is more suitable for rankings and quality assessment of segmentations than average Hausdorff distance.
An Essay on Dorothea Lange’s “Migrant Mother”

description: In this essay on Dorothea Lange’s well-known image, written for “The Politics of Seeing”, David Campany reflects upon the politics of imagery and its iconic status, arguing that the more they are seen, the more they are seen; and the more they circulate, the more they circulate – but the less they are understood. More often than not, photographs become iconic when they become default substitutes for the complexities of the history, people or circumstances they could never fully articulate but to which they remain connected, however tentatively.

Prologues and epilogues to English plays before 1714

description: But contributory to a history of the Prologues and Epilogues of English drama, the following chapters describe a year's gleanings from plays, newspapers, journals, miscellanies, and folio half-sheets that were put into print before 1714. Stage orations alone--those spoken and those intended to be spoken--are the subject of this account. Other Prologues and Epilogues, such as one meets in the literature without the playhouse, find no place here, for the Prologues and Epilogues of the theatre, written for human voice and gesture, are a type of literary composition that served a different purpose and evolved apart from its kin of the same denomination. There was no traveled road to follow in this investigation. No theories of other men's fabrication charted the field, despoiling it of adventure. So careering through years and years of Prologues and Epilogues that came before Pope wrote for Addison's Cato, never meeting with a historian of the type, one revels in this wealth of untried matter, though denied a likely pleasure of overturning some predecessor's cherished tenet. Like a myth that the people would not give up, Prologues and Epilogues continued long after the real reason for their existence was gone. Audiences enjoyed being told that they were the makers and destroyers of playwrights and players. They liked to have an actor come with begging knee to sue for their good will. And when, as the playwrights often complained, the plea of the Prologue and the Epilogue became nothing more than a gesture, some writers found a way to put new wine into cherished old bottles: stage-orations caught up the literary fads of the day, retailed news for the entertainment of their audiences, entered into the controversies of the hour, and dispensed town-talk to those men who would give their last twopence for news. The history of a form that related itself to the very life of the people and never entirely dropped out of use seems worth the writing, for it furnishes an interesting commentary upon English drama and English society

description: A series of novel 3-N,N-dimethylaminofunctionalized phosphinines were synthesized and structurally characterized. DFT calculations showed that these aromatic phosphorus heterocycles possess stronger π-donor and σ-donor properties compared to the parent phosphinine C5H5P. With CuBr ⋅ SMe2, the corresponding complexes of the type [(phosphinine)2CuBr]2 are formed, which show the classical terminal σ-coordination mode of the phosphorus donor towards the Cu(I) center. Upon reaction with AuCl ⋅ SMe2, mononuclear phosphinine-Au(I)Cl complexes could be obtained and crystallographically characterized. Moreover, the presence of a SiMe3-group and a donor-functionality provide the possibility for post-synthetic ligand modifications. With CuCl ⋅ SMe2 the phosphinine-based hydrochloride salts forms a rare Cu(I) complex with a Cu4Cl4-core, that contains two pairs of differently coordinating phosphinine ligands.

Womit es fraglich ist, ob Wirtschaftspädagog*innen im Unterricht auf die bekannten Defizite ihrer Berufsschüler*innen (Seeber, 2013) eingehen können. Bislang mangelt es an empirischer Evidenz zum mathematischen Fachwissen von Studierenden der Wirtschaftspädagogik. Um deren mathematisches Wissen zu testen, bedarf es eines Modells zum Fachwissen, welches den Anforderungen des Unterrichts genügt und der Ausbildung von Wirtschaftspädagog*innen angemessen ist. Bislang existiert ein solches Modell nicht. In diesem Artikel werden Überlegungen zu einem Modell zur Testung mathematischen Wissens von Wirtschaftspädagog*innen präsentiert.

description: Devoted to contemporary photography artistic practices, under the motto “Post­-Photographic Truths: Poetics vs Politics”, this text aims to question and discuss the drifts of contemporary photographic practices in our post-truth era. Rooted in the historiography of the medium, the poetics and the political are hypothetical boundaries that prevail in current photographic artistic practices. If the reoccurrence of the poetics beautiful image could be understood as a counter-reaction to the vulnerability of the myth of representation. Hence, the exhaustion of the mechanisms of representation and the political stance could be correlated with the photographic endeavour to represent the complexity of the outer world. The invited authors’ essays, reviewed papers and visual essays published on this issue aim to contribute to the critical discussion of this hypothetical quarrel, merging the notions of poetics and politics, while reaffirming the polysemy of photographs.

description: Not all hope is equal. For the Christian religion, hope is a theological virtue, and refers to the expectation of future life, beyond death. With the transformation of European society in a secular sense and the rise of individualism between the 17th and 18th centuries, hope becomes a program of political and social transformation, aimed at this world. In my contribution I trace the emergence of the concept of hope in social thought and, then, in sociology. My analysis begins with the Philosophie sociale (Paris, 1793) by Moses Dobruska (1753–1794), a pioneering and largely overlooked text that founds a new vision of social science. After Dobruska, I then devote my attention to the great thinkers of the early nineteenth century, Henri de Saint-Simon (1760–1825) and Auguste Comte (1798–1857), and then I move on to the work of Émile Durkheim (1858–1917). It is a historical perspective that has been neglected until now, and that allows us to appreciate the construction of an idea of hope that frees itself from religious determinants and is oriented toward society and the individuals who live in it, and that anticipates the utopias and failures of the social ideologies of the 20th century.

description: This review of Trading Zones: Camera Work in Artistic and Ethnographic Research edited by a number of researchers who also contribute presents the book in its methodological and artistic variety and in relation to other fields. While firmly situating itself in human-centered anthropological practice, at the edges it brushes against media theoretical frameworks it hardly engages. Contributions explore the possibilities, limitations and challenges the presence of the camera offers for research and creation, all the while focusing on topics such as ethics and human action. The book is an important contribution to visual ethnography and points toward ways anthropology can be used creatively in the arts. It also offers an impressive intersection of possibilities through the many examples described, illustrated and hyperlinked. It will be especially useful for those that seek immediate applicability.

description: Es scheint Konsens zu sein, dass mathematische Lerninhalte an Anwendungsszenarien außerhalb des Mathematikunterrichts angebunden werden sollten, um den Lernenden die Bedeutsamkeit ebendieser Lerninhalte für das alltägliche Leben zu verdeutlichen (z.B. Franke & Ruwisch, 2013; Leuders et al., 2011). Schlagworte wie Sachaufgaben, Modellierungen, Kontextualisierungen und Narrationen fallen in diesem Zusammenhang häufig und werden mal synonym genutzt, mal voneinander abgegrenzt. Hier wird der Begriff Lebensweltbezug genutzt. Ein Lebensweltbezug im Mathematikunterricht liegt nach dem zugrundeliegenden Begriffsverständnis dann vor, wenn mathematische Lerninhalte mit den vermeintlichen Erfahrungen und Interessen der Lernenden verbunden werden. Der Zusatz „vermeintlich“ soll hervorheben, dass die Quelle von Lebensweltbezügen vielfach Lehrpersonen oder Lehrwerke und nur selten die Lernenden selbst sind. Es bleibt demnach offen, ob die Lernenden tatsächlich Erfahrungen zum hinzugezogenen Sachverhalt gesammelt und Interesse für diesen haben. Bisherige Studien zu Lebensweltbezügen (und zugehörigen Begriffen) sind bislang vordergründig defizit- und produktorientiert. Im Fokus stehen „typische“ Fehler der Lernenden, mögliche Fehlerursachen, die stereotypische Gestalt vieler Lebensweltbezüge sowie die Meinungen Lehrender und Lernender zu Lebensweltbezügen im Mathematikunterricht (z.B. Gainsburg, 2008; Karakoç & Alacacı, 2015; Radatz, 1990; Wuolle, 2016). Ein prozessorientierter Blick auf die interaktiven Aushandlungsprozesse in Situationen mit einem Lebensweltbezug scheint bislang vernachlässigt (Ausnahmen sind bspw. Bauersfeld, 1991; Neth & Voigt, 1991). Darüber hinaus sind Lebensweltbezüge dann sinnstiftend und fördern nachhaltige Lernprozesse, wenn sie mathematisch reichhaltig, authentisch und für die Lernenden bedeutsam sind (z.B. Leuders et al., 2011). Dieser Beitrag beruht auf einem Promotionsvorhaben, dass der folgenden forschungsleitenden Fragestellung nachgeht: Wie wirken sich Lebensweltbezüge im Mathematikunterricht auf den Sprachgebrauch und die interaktive Bedeutungsaushandlung über den mathematischen Lerninhalt aus?

description: The “tablelands” in Taiwan are sedimentary terraces occurring in the foreland basin west of the Neogene mountain ranges. The Miaoli Tableland consists of elevated Late Quaternary sedimentary successions, representing a change from tidal to coastal and fluvial to eolian depositional environments. The present-day morphology is a result of combined processes, including differential tectonic uplift, ongoing fluvial aggradation, and incision. Selected deposits in 10 outcrops were sampled and studied by optical dating. The deposition of fluvial sediments started after the last interglacial (<100 ka) in the southeast of the tablelands. Uplift and sea-level lowering caused a base-level fall, resulting in a stepwise redeposition of the fluvial sediments. Additionally, enhanced remobilization of fluvial sediments occurred during the cold/dry climate during Marine Oxygen Isotope Stages (MIS) 4 and 2. The depositional ages of the coastal sediments enabled the estimation of long-term uplift rates of ca. 0.5 to 3.5 mm/yr. The eolian cover sediments yielded MIS 3 (east) to Holocene ages (west). Our results provide new insight into the interplay of climate, sea-level changes, remobilization of sediments, and tectonism leading to tableland formation during the Late Quaternary.

description: Das Net-Mathebuch (m2.net-schulbuch.de) ist ein digitales Mathematikschulbuch für die gymnasiale Oberstufe, welches sich durch seine Interaktivität, multimedialen Elemente, Feedbackoptionen und durch die Integration von GeoGebra auszeichnet (Brnic & Greefrath, 2022). Im Projekt KomNet-Math wird Lehrkräften und ihren Schüler*innen diese digitale Curriculum Ressource für ein Schuljahr zur Verfügung gestellt. Somit konnte das Net-Mathebuch auch im durch die Covid-19 Pandemie bedingten Distanzunterricht in diesen Mathematikkursen als Ressource zum Lehren und Lernen genutzt werden. Da wir dieses digitale Schulbuch aufgrund seiner Potenziale und dessen Einfluss auf den Lernerfolg als besonders geeignet für den Distanzunterricht einstufen (Brnic & Greefrath, 2022) und das Schulbuch als Schlüsselressource im Mathematikunterricht angesehen wird (Rezat et al., 2021), ist es von besonderem Interesse, ob und auf welche Weise dieses tatsächlich eingesetzt wurde. Dabei stellt sich die zentrale Frage, ob das digitale Schulbuch im Distanzunterricht lediglich für Wiederholungen und Übungen oder auch für das Erarbeiten neuer Themen genutzt wurde. Dies ist vor dem Hintergrund zu eruieren, dass Schüler*innen nicht im gewohnten Klassenraumsetting, sondern beispielsweise in asynchronen Lernformaten selbstständig arbeiten mussten. Eine solche Untersuchung ist von besonderer Relevanz, um einerseits mehr über den Einfluss der Pandemie auf den Mathematikunterricht zu erfahren, andererseits aber auch um Konsequenzen für zukünftige Distanzunterrichtsszenarien oder asynchrone Lernformate mit digitalen Unterrichtsmaterialien zu ziehen.

description: We investigate the translocation of stiff polymers in the presence of binding particles through a nanopore by two-dimensional Langevin dynamics simulations. We find that the mean translocation time shows a minimum as a function of the binding energy $ε$ and the particle concentration $ϕ$, due to the interplay of the force from binding and the frictional force. Particularly, for the strong binding the translocation proceeds with a decreasing translocation velocity induced by a significant increase of the frictional force. In addition, both $ε$ and $ϕ$ have an notable impact on the distribution of the translocation time. With increasing $ε$ and $ϕ$, it undergoes a transition from an asymmetric and broad distribution under the weak binding to a nearly Gaussian one under the strong binding, and its width becomes gradually narrower.

On memory and post-truth
Creators: name: Pinto Machado, Marta
Publisher: name: Journal of Science and Technology of the Arts

description: Facing an idea of post-truth, “post” as meaning to be beyond something, that signifies spatial distance, to go beyond the unrepresentable, this article means to understand the built memory around a constructed truth over a picture of a colonial priest also my great-grandfather of my Cape Verdean family, questioning the regime of truth in which it was made and the relationship within the truth production context. Taking this figure as a pretext to analyse the processes of memory, history and representation, it’s meant to understand an idea of truth.

Mechanism, External Purposiveness, and Object Individuation: from Mechanism to Teleology in Hegel's Science of Logic

subject: 100 Philosophie und Psychologie::100 Philosophie::102 Verschiedenes

description: This article is an investigation into Hegel's claim that teleology is the truth of mechanism, which Hegel puts forward in the objectivity section in the Science of Logic. Contrary to most accounts of this section of the Logic, I make a case for a reading of Hegel's conception of external purposiveness according to which the latter makes a positive contribution to the structural development of the concepts of the Logic. I argue that external purposiveness plays a major role in understanding the Hegelian claim of teleology as the truth of mechanism. More specifically, I argue that structures of external purposiveness provide the conditions for the individuation of mechanical objects.
Taste symmetry violation at finite temperature

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: Symmetries play a distinctive role at the high temperature phase transition in QCD. Therefore the spectrum of screening masses has been investigated with emphasis on taste breaking. Although taste violation is an UV effect the relevant operators could be temperature dependent. We have studied the meson screening masses in the temperature range between 140 MeV to 550 MeV. The computation has been performed using dynamical N_f = 2+1 gauge field configurations generated with the p4 staggered action. For temperatures below the transition an agreement with the prediction of staggered chiral perturbation theory has been found and no temperature effect can be observed on the taste violation. Above the transition the taste splitting still shows an O(a^2) behavior but with a temperature dependent slope.

description: The smart grid vision is to revitalize the electric power network by leveraging the proven sensing, communication, control, and machine learning technologies to address pressing issues related to security, stability, environmental impact, market diversity, and novel power technologies. Significant effort and investment have been committed to architect the necessary infrastructure by installing advanced metering systems and establishing data communication networks throughout the grid. Signal processing methodologies are expected to play a major role in this context by providing intelligent algorithms that fully exploit such pervasive sensing and control capabilities to realize the vision and manifold anticipated benefits of the smart grid. In this feature article, analytical background and relevance of signal processing tools to power systems are delineated, while introducing major challenges and opportunities for the future grid engineering. From grid informatics to inference for monitoring and optimization tools, energy-related issues are shown to offer a fertile ground for signal processing growth whose time has come.

Statistical Literacy in der Primarstufe fördern durch Nachvollziehen von Aussagen

description: Statistical Literacy ist die Fähigkeit, statistikhaltige Informationen insbesondere in den Medien zu verstehen und kritisch Stellung dazu nehmen zu können (Gal, 2002). Eine solche Fähigkeit ist aufgrund der zunehmenden Masse von Argumenten, Meinungen und Fake News in Social Media von zunehmender Bedeutung (Engel, 2017). Damit wird es zu einer Aufgabe für einen allgemeinbildenden Mathematikunterricht, Statistical Literacy für alle Lernenden sicherzustellen. Bislang existieren nur relativ wenige empirische Erkenntnisse über den Stand von Statistical Literacy in den Schulen oder über Verläufe von Lernprozessen zur Statistical Literacy. Schulbuchanalysen deuten zudem an, dass auch bei der Entwicklung von Aufgaben Handlungsbedarf besteht (Büscher, im Druck). In diesem Beitrag wird daher eine Studie vorgestellt, die Möglichkeiten für die Förderung von Statistical Literacy identifiziert und die situativen Wirkungsweisen von Lehr-Lern-Arrangements in den Lernprozessen rekonstruiert. Dabei wird die Primarstufe in den Blick genommen, um möglichst frühe Anknüpfungspunkte für die Entwicklung von Statistical Literacy identifizieren zu können.
Yukawa effects on the clock onboard a drag-free satellite

description: The Yukawa correction to the Newtonian gravitational force is accepted as a parameterization of deviations from the inverse-square law of gravity which might be caused by new physics beyond the standard model of particles and the general theory of relativity. We investigate these effects on the clock onboard a drag-free satellite: dynamics of the satellite and influence on the time transfer link. We find the Yukawa signal in the time transfer is much harder to detect with current state of clocks than those effects on the dynamics, especially the secular change of periastron, by laser ranging in the case of an artificial Earth satellite carrying a frequency standard with an orbit of $a=10^7$\,m and $e=0.01$.

The effects of narratives and popularity cues on signing online petitions in two advanced democracies

description: Online petitions have become a widespread vehicle for contemporary political participation. While research tends to focus on individual factors for potential petitioners that influence signing, less attention has been paid to the influence of the actual text of petitions. This paper uses data from an original web-based survey experiment in Australia and Germany to test the influence of content factors: narratives (i.e., stories based on individual experiences and emotions) and popularity cues (i.e., high numbers of signatures) across two issues: climate change and welfare policy. We find that narratives within petition texts involve readers through the mechanism of transportation and motivate them to sign petitions, as do popularity cues. The effects of narratives were found across both countries but tended to be stronger in Germany than in Australia. We argue that our novel framework can be used for future research on how the presentation of issues shape contemporary political participation.
Sofic profile and computability of Cremona groups

description: In this paper, we show that Cremona groups are sofic. We actually introduce a quantitative notion of soficity, called sofic profile, and show that the group of birational transformations of a d-dimensional variety has sofic profile at most polynomial of degree d. We also observe that finitely generated subgroups of the Cremona group have a solvable word problem. This provides examples of finitely generated groups with no embeddings into any Cremona group, answering a question of S. Cantat.

Eine Möglichkeit zur Spezifizierung und Strukturierung des Themengebietes stellt der 4-Stufen-Ansatz (Hußmann & Prediger, 2016) dar, bei dem der Unterrichtsgegenstand auf formaler, semantischer, konkreter und empirischer Ebene analysiert wird und als Ergebnis verschiedene Lernpfade im Rahmen der fachdidaktischen Entwicklungsforschung designt werden.
All The Sites: Fragments Of A Close Landscape
Creators: name: Castanho, André
Publisher: name: Journal of Science and Technology of the Arts
Year: 2022

description: All The Sites (Todos Os Sítios) is an exercise of critical reflection on the contemporary landscape. It brings together a set of photographs, which constitute its body of visual documents, and a written argument that aims to inform the intentions and paradigms of the photographs. This article organizes this reflection through two moments: the first concerns the definition of the term site, based on a perception of the landscape as a cultural construction, an expression coined by WJT Mitchell, and the second, through the work of three photographers – Eugène Atget, Walker Evans and Guido Guidi, seeks to situate the visual paradigms of photographs of All the Sites and the discourse that is inherent to them.
