I stedet for et abstract kommer her begyndelsen på anmeldelsen:
Trots den centrala betydelse som den årliga muslimska vallfärden till Mecka och Medina tillskrivs av muslimer världen över, finns det inte mycket litteratur som fokuserar på hajj ur ett skandinaviskt perspektiv. Denna publikation, som är ett samarbete mellan tre göteborgska institutioner – Institutet för språk och folkminnen, Göteborgs universitet och Världskulturmuseet – är därför välkommen. (...)
Viñetas de vida: una propuesta de Aprendizaje-Servicio a través del cómic
Authors: Espinosa-Guerri Guadalupe 
Published: November 2018

El enfoque Aprendizaje-Servicio consiste en aprender ejecutando tareas que repercutan positivamente en la comunidad. A través de este enfoque proponemos una unidad didáctica para los niveles C1-C2. La unidad se divide en tres partes: en la primera se introduce el tema mediante tareas de comprensión e interacción oral. En la segunda, se trabaja la comprensión lectora a partir del cómic Viñetas de vida, cuyo objetivo es sensibilizar a la población de la necesidad de la cooperación internacional. Finalmente, en la tercera parte, se realiza la tarea final de expresión escrita que consiste en la de redacción de un informe en que se exponen datos relevantes sobre la cooperación y se propone un plan de acción viable para el grupo. Con esta unidad didáctica se pretende, pues, involucrar al alumnado en el aprendizaje de la lengua mientras actúan sobre necesidades reales del entorno.
En el fondo hablamos la misma lengua (o no): tipologías lingüísticas y universales en la clase de E/LE
Authors: Gallego Martí Carlos 
Published: November 2018

El estudio de las tipologías lingüísticas(esto es, de las semejanzas y disimilitudes de las diferentes lenguas presentes en el aula de E/LE con respecto a la lengua española) así como el de los universales(principios comunes a todas las lenguas conocidas del mundo) constituye una herramienta de indudable valor pedagógico puesto que permite a los alumnos una comprensión global del español, de sus límites estructurales y de la particular concepción del mundo que supone comunicarse en este idioma. Asimismo, contribuye a prevenir las transferencias gramaticales equivocadas entre la lengua materna del estudiante y la lengua meta. Finalmente, este enfoque proporciona una visión científica del hecho lingüístico, aspecto que favorece que el nuevo sistema gramatical que el alumno va a aprender sea percibido como un modelo riguroso y coherente, y no como un compendio de normas y relaciones más o menos caprichosas.
El desarrollo sostenible ¡Tu papel es importante!
Authors: Piraccini Miriam 
Published: November 2018

Se quiere planear a los alumnos el tema del desarrollo sostenible y de los problemas que afectan al medio ambiente; ellos trabajarán en casa con diferentes recursos que la profesora ha cargado en Blendspace, una plataforma virtual. Posteriormente se ampliará y se discutirá sobre este tema en clase y, como tarea final, se pedirá a los alumnos que creen un folleto con los consejos para salvar el planeta. Serán los alumnos mismos a evaluar los trabajos y a elegir los mejores, que serán presentados a los compañeros de otros cursos.
Márcate un discurso con Cortázar
Authors: Rivera León Lorena 
Published: November 2018

Por su frecuencia de aparición y el papel que desempeñan en las inferencias pragmáticas, los marcadores del discurso resultan indispensables en la adquisición de la competencia comunicativa a la que debe aspirar todo estudiante de E/LE. Sin embargo, los docentes afrontan no pocas dificultades para trabajar con ellos, entre otras cosas porque son escasos y a menudo erráticos los materiales diseñados específicamente para enseñarlos. Con el propósito de paliar este déficit, presentamos una secuencia didáctica pensada para un nivel C1 y ensamblada como una aproximación coherente a la figura de Julio Cortázar. En el tratamiento de los marcadores discursivos adoptamos la perspectiva cognitivo-pragmática de autores como Martín Zorraquino y Portolés (1999) y Pons Bordería (2000) al mismo tiempo que seguimos las recomendaciones del MCERy el PCIC, subrayando expresamente la necesidad de que el alumno use estrategias de reflexión y toma de conciencia.

First steps towards assessing the evolutionary history and phylogeography of a widely distributed Neotropical grassland bird (Motacillidae:Anthus correndera)
Authors: Norambuena Heraldo V. , Van Els Paul , Muñoz-Ramírez Carlos P. , Victoriano Pedro F. 
Published: November 2018

Grasslands in southern South America are extensive ecosystems which harbor a unique biodiversity; however, studies on the evolution of their taxa are scarce. Here we studied the phylogeography and population history of the Correndera Pipit (Anthus correndera), a grassland specialist bird with a large breeding distribution in southern South America, with the goals of investigating its phylogeographic history and relate it to the historical development of South American grasslands. The mitochondrial NADH dehydrogenase subunit II gene (ND2) was sequenced in 66 individuals from 19 localities and the intron 9 of the sex-linked gene for aconitase (ACOI9) was sequenced from a subset of those individuals, including all five subspecies ofA. correndera, as well as the closely relatedA. antarcticus. Phylogenetic analysis revealed two distinct lineages within the complex: the first (A) corresponding to Andean subspeciesA. c. calcaratusandA. c. catamarcaeand the second (B) including birds traditionally assigned toA. c. correndera,A. c. chilensis,A. c. grayiand some individuals ofA. c. catamarcae.A. antarcticusis nested within this second lineage. These results were also supported by evidence of niche divergence for variables associated with precipitation. The oldest split between clade A and B was estimated atc.0.37 Mya, during the middle Pleistocene. Species distribution models for the present and the Last Glacial Maximum (LGM) suggest that grassland areas in southern South America remained relatively stable, in contrast to the general view of a reduction in grassland cover in South America since the LGM. Recent divergences and low phylogeographic structure (for lowland vs. highland geographic groups, intra-population genetic variance was greater than inter-groups; e.g., for ACOI9: 95.47% and ND2: 51.51% respectively), suggest widespread gene flow between lowland populations.

It motivates why applying machine learning in science education could offer novel opportunities for data-driven modeling of learning processes and answering novel research questions. It also introduces the grand themes of this textbook: providing basics of machine learning and natural language processing, arguing for the importance of augmenting human analytic capabilities with what machine learning has to offer, and introducing the challenges that might occur when applying machine learning in science education.
Unsupervised ML with Text Data
Authors: Hall Kevin , Krist Christina 
Published: February 2025

Abstract
This chapter builds on the techniques introduced in the previous Chaps. 12 and 13. Specifically, we will demonstrate how unsupervised pattern recognition approaches can be applied to text data to answer a research question. Because pre-processing and “knowing” your data are especially important when using unsupervised approaches with text, we will introduce additional techniques with an emphasis on exploratory data analysis tools such as token frequency analysis, basic text analytics, and n-gram analysis to explore large text-based datasets before using this information in support of the application of unsupervised natural language processing (NLP) techniques.
Risks and Ethical Considerations in the Context of Machine Learning Research in Science Education
Authors: D’Angelo Cynthia M. 
Published: February 2025

Abstract
Besides the tremendous potentials of machine learning (ML) methods, many ethical challenges such as biased datasets with regard to gender or race have to be considered. In this chapter, a conclusive reflection on the particular challenges in science education research based on the case studies and prior research will be outlined. Paths to address these challenges will finish this chapter.
EU, Russia, and the Theory of Hegemonic Power
Authors: Burmester Isabell 
Published: February 2025

Abstract
This chapter establishes a conceptual framework for comparing the influence of the EU and Russia in their shared neighbourhood using the more generic concepts of hegemony and power. It develops three ideal-typical mechanisms of hegemonic power: coercion, prescription, and co-optation, based on existing literature. Coercion involves overt conflicts of interests and threats to influence target states' actions. Prescription operates through the imposition of rules and standards, shaping behaviour based on a sense of obligation. Co-optation involves reshaping ideas, values, and beliefs, ensuring compliance through consent rather than coercion. The chapter also outlines the research design and introduces the cases of Moldova and Armenia, explaining how these mechanisms are applied and examined. This structured comparison allows for a nuanced analysis of the similarities and differences in EU and Russian influence, providing a comprehensive understanding of their hegemonic power dynamics in the region.
EU and Russian Coercion: Manipulating the Cost-Benefit Calculations of the Moldovan and Armenian Governments
Authors: Burmester Isabell 
Published: February 2025

Abstract
The third chapter assesses the exploitation of existing economic and security dependencies (i.e., coercion) by the EU and Russia. It presents a systematic comparison of their uses of coercive actions towards Moldova and Armenia and an analysis of the perceptions of local actors. Both the EU and Russia coerced Moldova and Armenia, but the difference was in the institutionalisation of the mechanism. The chapter details the coercion mechanism, illustrating how threats influence the political elite’s preferences. The effectiveness of coercion depends on the communicated threats, rewards, and demands, and how these are perceived by the target state’s political elite. It also considers the existing interdependencies with other powers and the local context in which coercive activities are received. EU conditionality was perceived as positive and legitimate, associated with economic opportunities and reforms beneficial to the countries. Russian coercive actions were seen as negative and threatening, creating fear and resistance. This difference in perception highlights the importance of normative justification in the effectiveness of coercive strategies. This comparative analysis provides valuable insights into the dynamics of hegemonic power in the shared neighbourhood of the EU and Russia.
EU and Russian Prescription: Setting Rules and Standards for Food Safety
Authors: Burmester Isabell 
Published: February 2025

Abstract
This chapter delves into the prescription of food safety rules by the EU and the Eurasian Economic Union (EAEU) in Moldova and Armenia. While the EU’s influence through its market power and the Brussels effect is well-documented, the EAEU, led by Russia, has also emerged as a significant player in the region. The EAEU’s approach to food safety, however, contrasts starkly with the EU’s emphasis on ensuring safe production processes. Moldovan and Armenian actors perceived EU standards as superior, associating them with higher quality and safety for consumers, despite the higher compliance costs. Conversely, EAEU standards were viewed as lower and more attainable, a reflection of the legacy Soviet system integrated with new, albeit inconsistent, rules. This chapter examines how these differing standards and approaches influenced local regulatory practices and perceptions, highlighting the complexities and challenges faced by Moldova and Armenia in navigating the overlapping influences of these two powerful entities. The findings underscore the nuanced dynamics of regional hegemony in the domain of food safety and the varied responses of local actors to external regulatory prescriptions.
Einleitung
Authors: Präger Fabian 
Published: February 2025

Zusammenfassung
Die Zeit der Verbrennung von fossilen Energieträgern neigt sich dem Ende zu. Das Anthropozän scheint sich seinem Zenit zu nähern (Brunnengräber 2021a; Renn und Scherer 2017) und die Überschreitung von planetaren Grenzen und die Erreichung von Klimakipppunkten gefährdet die Menschlichkeit als Ganzes (Richardson u. a. 2023). Das menschengeschaffene, fossil-fissile Energiesystem steht vor einem großen Umbruch und wehrt sich gegen die Systemtransformation. Dies impliziert, dass für ein 100%-Erneuerbare-Energiesystem (100%-EES) ein einfacher Übergang („transition“) zur verstärkten Nutzung Erneuerbarer Energien (EE) nicht ausreicht. Aufgrund der zunehmend eskalierenden Klimakrise mit global und lokal verheerenden Auswirkungen sowie den Herausforderungen der Polykrise (Petschow 2024; Sharp, Hofmann, und Petschow 2024), muss dem Modell ein umfassenderer Ansatz entgegengesetzt werden. Dieser Ansatz wird beschrieben mit dem Konzept der sozial-ökologischen Transformation (SÖT) (Heinrich Böll Stiftung Studienwerk 2022), hin zu einer 100%-Erneuerbare-Energien-Ökonomie (100%-EEÖ).
Atomwende
Authors: Präger Fabian 
Published: February 2025

Zusammenfassung
In der Sektoranalyse des sozio-technischen System der Atomenergie werden historische Entwicklungen sowie gegenwärtige und zukünftige Handlungsfelder der Atomwende untersucht. Die Atomwende beschreibt den Prozess der Abkehr von der Nutzung der Atomenergie und die Hinwendung zur Entsorgung radioaktiver Abfälle in Deutschland. In diesem Kapitel wird dieser Wendeprozess als bedeutender Teil der Energiewende dargestellt, der gleichzeitig eine Voraussetzung für einen sozialverträglichen und zeitnahen Entsorgungsprozess der gefährlichen und langlebigen Hinterlassenschaften des Atomzeitalters ist. Der Fokus liegt auf den Auswirkungen und dem Zusammenspiel mit der sozial-ökologischen Transformation sowie auf den gegenwärtigen Herausforderungen bei der Endlagersuche für hochradioaktive Abfälle.
Transformationen von Literatur in Zeiten postdigitaler Öffentlichkeiten
Authors: Friedrich Sabine 
Published: February 2025

Zusammenfassung
Der folgende Beitrag untersucht die Strukturen, die Produktions- und Rezeptionsbedingungen literarischer Texte in differenten zeitgenössischen Öffentlichkeiten vor dem Hintergrund der digitalen Transformationsprozesse der letzten 25 Jahre. Anhand exemplarischer Analysen unterschiedlicher digitaler Subgenres wird analysiert, in welcher Weise sich die Grundkonstituenten digitaler Texte so radikal verändern, dass es zu einer weitreichenden Rekonzeptualisierung des Literaturbegriffs kommt. Zunächst geht der Beitrag auf Textstrukturen ein, die keine feste, abgeschlossene Form mehr haben, sondern sich auch nach ihrer ersten Veröffentlichung dynamisch unter Beteiligung von digitalen communities weiterentwickeln. In einem zweiten Schritt wird die experimentelle Kombination unterschiedlicher medialer Formate untersucht, die dazu führt, dass die Literatur Bestandteil einer multimedialen Performanz- und Installationskunst wird. Die Aufweichung der Grenzen zwischen fiktionaler Diegese und außerfiktionaler Diskurswelt ist ein weiterer wichtiger Aspekt. Abschließend werden die Veränderungen der Kommunikationsbedingungen und der daraus resultierenden Neubestimmung von Literatur und kulturellen Verankerung in den postdigitalen Öffentlichkeiten erörtert. In ähnlicher Weise wie die Avantgardekunst des 20. Jahrhunderts scheint die digitale Literatur vor allem die grundsätzliche Frage aufzuwerfen: Was können wir heute unter Literatur verstehen?
„Spukhafte Öffentlichkeit“. Nicolas Borns Roman Die Fälschung (1979) und seine Verhandlungen mit der außerliterarischen Realität
Authors: Niefanger Dirk 
Published: February 2025

Zusammenfassung
Der Beitrag analysiert Nicolas Borns Erfolgsroman Die Fälschung (1979) hinsichtlich seiner Entstehenskontexte, seiner Positionierung im kulturellen Feld und seiner medialen Transformationen (Film, Hörbuch). Besonderes Gewicht bei der Analyse bekommt der im Roman reflektierte Öffentlichkeitsbezug von literarischem und journalistischem Schreiben. Verhandelt wird etwa die private Krise des Protagonisten, die ihn zu kritischer Distanz zum Sensationsjournalismus seiner Zeit führt. Als Möglichkeit deutet sich ihm ein dichterisches Schreiben an, das die eigene Involviertheit wie das reale Leid gleichermaßen mitbedenkt. Der historische Hintergrund des Gegenwartsromans, seine Auseinandersetzung mit dem Krieg im Libanon, sowie seine wirklichkeitsnahe Verfilmung rücken auch im öffentlichen Diskurs über den Roman und seine medialen Transformationen verstärkt das Verhältnis von Fiktion und außerliterarischer Realität in den Blick. Das Faktische soll im Fiktionalen durchscheinen und das Fiktionale im Faktischen erkennbar bleiben, auch wenn Gattung und Medium keineswegs faktuale Ansprüche erheben. Grundsätzlich gilt dies für Roman, Film und Hörbuch gleichermaßen, auch wenn die ästhetischen Lösungen differieren. Die Analyse des Romans und seiner medialen Transformationen zeigt am konkreten Fall einige Momente des Strukturwandels der Öffentlichkeit seit den späten 1970er Jahren: die Macht der Bilder, die je differente Anbindung der Fiktion ans Faktische, die Sensationslust journalistischer Kriegsberichterstattung und ihrer Verfilmung sowie einen neuen Purismus bei der Darstellung des Bürgerkrieges im Hörbuch.
Special Hermitian structures on suspensions
Authors: Fino Anna , Grantcharov Gueo , Verbitsky Misha 
Published: February 2025

Abstract
Motivated by the construction based on topological suspension of a family of compact non-Kähler complex manifolds with trivial canonical bundle given by Qin and Wang (Geom Topol 22:2115–2144, 2018), we study toric suspensions of balanced manifolds by holomorphic automorphisms. In particular, we show that toric suspensions of Calabi–Yau manifolds are balanced. We also prove that suspensions associated with hyperbolic automorphisms of hyperkähler manifolds do not admit any pluriclosed, astheno-Kähler or p-pluriclosed Hermitian metric. Moreover, we consider natural extensions for hypercomplex manifolds, providing some explicit examples of compact holomorphic symplectic and hypercomplex non-Kähler manifolds. We also show that a modified suspension construction provides examples with pluriclosed metrics.
Flavonoid-converting capabilities of Clostridium butyricum
Authors: Braune Annett 
Published: February 2025

Abstract

Clostridium butyricum inhabits various anoxic environments, including soil and the human gut. Here, this common bacterium comes into contact with abundant plant-derived flavonoids. Metabolization of these bioactive polyphenols has been studied in recent years, particularly focusing on gut bacteria due to the proposed health-promoting properties of these dietary constituents. Based on an initial report in 1997 on eriodictyol degradation (Miyake et al. 1997, J Agric Food Chem, 45:3738–3742), the present study systematically investigated C. butyricum for its ability to convert a set of structurally diverse flavonoids. Incubation experiments revealed that C. butyricum deglycosylated flavonoid O-glucosides but only when glucose was absent. Moreover, aglycone members of flavone, flavanone, dihydrochalcone, and flavanonol subclasses were degraded. The C-ring cleavage of the flavanones, naringenin and eriodictyol, was stereospecific and finally resulted in formation of the corresponding hydroxyphenylpropionic acids. Stereospecific C-ring cleavage of the flavanonol taxifolin led to taxifolin dihydrochalcone. C. butyricum did neither cleave flavonols and isoflavones nor catalyze de-rhamnosylation, demethylation, or dehydroxylation of flavonoids. Genes encoding potential flavonoid-metabolizing enzymes were detected in the C. butyricum genome. Overall, these findings indicate that C. butyricum utilizes flavonoids as alternative substrates and, as observed for the dihydrochalcone phloretin, can eliminate growth-inhibiting flavonoids through degradation.

Key points

• Clostridium butyricum deglycosylated flavonoid O-glucosides.

• Clostridium butyricum converted members of several flavonoid subclasses.

• Potential flavonoid-metabolizing enzymes are encoded in the C. butyricum genome.
Engineering human/simian rotavirus VP7 reassortants in the absence of UTR sequence information
Authors: Valusenko-Mehrkens Roman , Johne Reimar , Falkenhagen Alexander 
Published: February 2025

Abstract
Recently developed plasmid-based reverse genetics systems for rotavirus A (RVA) enable rapid engineering of reassortants carrying human RVA antigens. However, complete genome segment sequences are required for successful generation of such reassortants, and sequencing of the untranslated regions (UTRs) of field strains is often not accomplished. To address this problem, we established a system that permits the generation of reassortants using only the open reading frame (ORF) nucleotide sequence information. Plasmids containing the VP7-ORF nucleotide sequence of six human RVA field strains (genotypes G2, G5, G8, G9, G12 and G29) derived from GenBank and flanked by the UTR sequences of simian RVA strain SA11 were constructed. Using these plasmids, four VP7 (G2, G5, G9 and G12) reassortants in an SA11 backbone were successfully generated. In contrast, the G8 and G29 reassortants were not viable. BLASTp search of the G8 and G29 sequences revealed an unusual amino acid substitution in each sequence, which was not present in related field strains. Site-directed reversion of the corresponding C656T mutation in G8 led to effective rescue of reassortant virus. However, reverting the G84C mutation in G29 did not result in replicating virus. The results suggest that most human RVA VP7 UTRs can be substituted with simian RVA UTRs. However, generation of reassortants might be impeded by potential sequencing errors or intrinsic reassortment limitations. The established system could help to broaden the antigenic repertoire for rapid engineering of potential novel RVA vaccine strains.

Key Points

• Generation of diverse rotavirus vaccine strains is impeded by missing UTR sequences.

• UTRs from SA11 can be used instead of missing UTR sequences from field strains.

• Human RVA reassortants of genotypes G2, G5, G8, G9, G12 were successfully rescued.
