While each analysis has its own merits and shortcomings, I argue that a pragmatic analysis that does not make appeal to syntactic configurations is better equipped to deal with many of the complex and delicate facts surrounding intervention effects.

This workshop aims at discussing common learners’ problems reported in the literature and reflect on designing adequate feedback interventions with the use of learning data. Our aim is three-fold: a) to pinpoint MOOC aspects that impact the planning of feedback, b) to explore the use of learning data in designing feedback strategies, and c) to propose design guidelines for developing and delivering scaffolding interventions for personalized feedback in MOOCs. To do so, we will carry out hands-on activities that aim to involve participants in interpreting learning data and using them to design adaptive feedback. This workshop appeals to researchers, practitioners and MOOC stakeholders who aim to providing contextualized scaffolding. We envision that this workshop will provide insights for bridging the gap between pedagogical theory and practice when it comes to feedback interventions in MOOCs.

T1 - Varieties of Supernatural Depictions BT - Classics in Contemporary Media JF - thersites 17 N2 - This article proposes several conceptual frameworks for examining the widespread use of classical intertexts depicting the supernatural in popular media. Whether the supernatural is viewed as reality or simply a trope, it represents the human capacity and desire to explore worlds and meanings beyond the obvious and mundane. Representations of classical gods, heroes, and monsters evoke the power of mythic stories to probe and explain human psychology, social concerns, philosophical questions, and religious beliefs, including belief about the paranormal and supernatural. The entertainment value of popular media allows creators and audiences to engage with larger issues in non-dogmatic and playful ways that help them negotiate tensions among various beliefs and identities. This paper also gives an overview of the other articles in this journal issue, showing overlapping themes and patterns that connect with these tensions. By combining knowledge of classical myths in their original contexts with knowledge about contemporary culture, classical scholars contribute unique perspectives about why classical intertexts dominate in popular media today.

T1 - Massive Wolf-Rayet stars on the verge to explode BT - the properties of the WO stars JF - Wolf-Rayet Stars : Proceedings of an International Workshop held in Potsdam, Germany, 1.–5. June 2015 N2 - The enigmatic oxygen-sequence Wolf-Rayet stars represent a rare stage in the evolution of massive stars. Their properties can provide unique constraints on the pre-supernova evolution of massive stars. This work presents the results of a quantitative spectroscopic analysis of the known single WO stars, with the aim to obtain the key stellar parameters and deduce their evolutionary state.X-Shooter spectra of the WO stars are modeled using the line-blanketed non-local thermal equilibrium atmosphere code cmfgen. The obtained stellar parameters show that the WO stars are very hot, with temperatures ranging from 150 kK to 210 kK. Their chemical composition is dominated by carbon (>50%), while the helium mass fraction is very low (down to 14%). Oxygen mass fractions reach as high as 25%. These properties can be reproduced with dedicated evolutionary models for helium stars, which show that the stars are post core-helium burning and very close to their eventual supernova explosion. The helium-star masses indicate initial masses or approximately 40 - 60M⊙.Thus, WO stars represent the final evolutionary stage of stars with estimated initial masses of 40 - 60M⊙. They are post core-helium burning and may explode as type Ic supernovae within a few thousand years.

Contributions from the STM-current and from the non-adiabatic couplings are taken into account using only first principle models. The slight asymmetry of the tunnelling rates with respect to the potential bias sign inferred from experimental observations is reproduced by weighting the contributions of the metal acceptor–donor states for the propagation of the impinging electrons. The quasi-thermal inelastic collision mechanism is treated perturbatively. The influence of hydrogen pre-coverage is also investigated using new potential energy surfaces obtained from periodic density functional theory calculations. Fully quantum dynamical simulations of the system evolution are performed by solving the Pauli master equation, providing insight into the reaction mechanism of STM manipulation of subsurface hydrogens. It is observed that the hydrogen impurity favors resurfacing over occupation of the bulk and subsurface sites whenever possible. The present simulations give strong indication that the experimentally observed protuberances after STM-excitation are due to hydrogen accumulating in the vicinity of the surface.

They are not literature in the sense of belles letters, but they should not be underestimated in their political, social and personal importance. No other printed product is as closely linked with everyday life as the newspapers. The day begins under their influence, and their contents mirror the events of the day with varying accuracy. Newspapers are strongly reader-oriented. They want to inform, but they also want to instil opinions. Specific choices of information shape the content level. Specific choices of language are resorted to in order to spread opinions and viewpoints. Language creates solidarity between the producers and the consumers of newspapers and thereby supports ideologies by specifically targeted linguistic means. Other strategies are employed for the same purpose, too. Visual aspects are of great importance, such as the typographical layout, the use of pictures, drawings, colours, fonts, etc.[...] Y1 - 2007 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:kobv:517-opus-19351 ER - TY - CHAP A1 - Tronicke, Jens T1 - Patterns in geophysical data and models N2 - Interdisziplinäres Zentrum für Musterdynamik und Angewandte Fernerkundung Workshop vom 9. - 10.

The bulk of pre-mRNAs are processed by canonical nuclear poly(A) polymerase (PAPS). Both vertebrate and higher-plant genomes encode more than one isoform of this enzyme, and these are coexpressed in different tissues. However, in neither case is it known whether the isoforms fulfill different functions or polyadenylate distinct subsets of pre-mRNAs. This thesis shows that the three canonical nuclear PAPS isoforms in Arabidopsis are functionally specialized owing to their evolutionarily divergent C-terminal domains. A moderate loss-of-function mutant in PAPS1 leads to increase in floral organ size, whereas leaf size is reduced. A strong loss-of-function mutation causes a male gametophytic defect, whereas a weak allele leads to reduced leaf growth. By contrast, plants lacking both PAPS2 and PAPS4 function are viable with wild-type leaf growth. Polyadenylation of SMALL AUXIN UP RNA (SAUR) mRNAs depends specifically on PAPS1 function. The resulting reduction in SAUR activity in paps1 mutants contributes to their reduced leaf growth, providing a causal link between polyadenylation of specific pre-mRNAs by a particular PAPS isoform and plant growth. Additionally, opposite effects of PAPS1 on leaf and flower growth reflect the different identities of these organs. The overgrowth of paps1 mutant petals is due to increased recruitment of founder cells into early organ primordia whereas the reduced leaf size is due to an ectopic pathogen response. This constitutive immune response leads to increased resistance to the biotrophic oomycete Hyaloperonospora arabidopsidis and reflects activation of the salicylic acid-independent signalling pathway downstream of ENHANCED DISEASE SUSCEPTIBILITY1 (EDS1)/PHYTOALEXIN DEFICIENT4 (PAD4). Immune responses are accompanied by intracellular redox changes. Consistent with this, the redox-status of the chloroplast is altered in paps1-1 mutants. The molecular effects of the paps1-1 mutation were analysed using an RNA sequencing approach that distinguishes between long- and short tailed mRNA. The results shown here suggest the existence of an additional layer of regulation in plants and possibly vertebrate gene expression, whereby the relative activities of canonical nuclear PAPS isoforms control de novo synthesized poly(A) tail length and hence expression of specific subsets of mRNAs. N2 - Polyadenylierung von prä-mRNAs ist entscheidend für den Export aus dem Zellkern, die Stabilität und die Translation der reifen mRNAs und dadurch für die Genexpression. Der Großteil der mRNAs wird durch sogenannte canonische Poly(A) Polymerasen (cPAPS) prozessiert. Die Genome von sowohl Wirbeltieren als auch Pflanzen kodieren mehr als eine Isoform dieser Enzyme, welche gleichzeitig in verschiedenen Geweben exprimiert werden. Es ist jedoch kein Beispiel bekannt, das zeigt, ob die verschiedenen Isoformen unterschiedliche Funktionen einnehmen bzw. verschiedene Untergruppen von mRNAs polyadenylieren. Diese Arbeit zeigt, dass drei canonische PAPS Isoformen in Arabidopsis thaliana aufgrund ihrer evolutionär unterschiedlichen C-terminalen Domänen spezialisierte Funktionen haben. Eine schwache Verlust-Mutation im PAPS1 Gen bewirkt eine Vergrößerung der Blütenorgane, während die Blattgröße vermindert ist. Eine starke Verlust-Mutation bewirkt zusätzlich einen Defekt der männlichen Keimzellen. Im Gegenzug dazu sind Mutanten des PAPS2 oder PAPS4 Gens gesund und zeigen ein normales Wachstum. Polyadenylierung von SMALL AUXIN UP RNA (SAUR) mRNAs hängt spezifisch von der Funktion von PAPS1 ab. Die daraus entstehende Reduzierung der SAUR Aktivität in den paps1 Mutanten trägt zur Verringerung der Blattgröße bei und stellt eine kausale Verbindung zwischen Polyadenylierung spezifischer mRNAs durch bestimmte PAPS Isoformen und Pflanzenwachstum dar. Zusätzlich spiegeln die unterschiedlichen Effekte von PAPS1 auf Blüten und Blätter die Identitäten dieser Organe wieder. Das übermäßige Wachstum der mutanten Petalen beruht auf einer erhöhten Anzahl an Gründer-Zellen im frühen Primordium, wohingegen die verminderte Blattgröße auf eine ektopische Pathogen Antwort zurückzuführen ist. Diese konstitutive Immunantwort bewirkt eine erhöhte Resistenz der Mutanten gegenüber dem biotrophen Oomyceten Hyaloperonospora arabidopsidis und reflektiert die Aktivierung des Salizylsäure unabhängigen Signalweges von ENHANCED DISEASE SUSCEPTIBILITY1 (EDS1)/PHYTOALEXIN DEFICIENT4 (PAD4). Immunantworten sind von Veränderungen des intrazellulären Redoxpotenzials gekennzeichnet. Damit übereinstimmend zeigen die Chloroplasten der paps1-1 Mutanten ein verändertes Redoxpotenzial. Zur genaueren Aufklärung der molekularen Effekte der paps1 1 mutation wurde eine RNA-Sequenzierungsmethode verwendet, die zwischen mRNAs mit langem oder kurzem Poly(A) Schwanz unterscheidet. Die Aktivitäten der verschiedenen canonischen PAPS Isoformen kontrollieren die Länge des neu synthetisierten poly(A) Schwanzes und damit die Expression spezifischer Untergruppen von mRNAs. Dadurch lassen die hier gezeigten Ergebnisse eine weitere Ebene der Genregulierung in Pflanzen, und möglicherweise auch in anderen Eukaryoten, vermuten.

Sugar-cane derived carbohydrates are very abundant in Brazil and are the cheapest sugars available in the market, with more than 400 million tons of sugarcane processed in the year 2007. The objective of this work was to study the preparation of sugar acrylates from free sugars and free acrylic acid, thus avoiding the previous preparation of protected sugar derivatives, such as glycosides, or activated acrylates, such as vinyl acrylate. RESULTS: Lipase catalyzed esterification of three mono- and two disaccharides with acrylic acid, in the presence or absence of molecular sieves was investigated. The reactions were monitored by high-performance liquid chromatography (HPLC) and the products were analyzed by matrix-assisted laser desorption ionization–time of flight (MALDI-TOF) mass spectrometry. The main products are mono- and diacrylates, while higher esters are formed as minor products. The highest conversion to sugar acrylates was observed for the D-glucose and D-fructose, followed by D-xylose and D-maltose. Molecular sieves had no pronounced effect on the conversion CONCLUSIONS: A feasible method is described to produce and to characterize sugar acrylates, including those containing more than two acrylate groups. The process for production of these higher esters could potentially be optimized further to produce molecules for cross-linking in acrylate polymerization and other applications. The direct enzymatic esterification of free carbohydrates with acrylic acid is unprecedented.

Whereas the zwitterionic polymethacrylates studied exhibit liquid-like short-range order, the polyacrylate analog exhibits an ordered double-layered superstructure.

The novel critically analyses the capitalistic, morally flawed and standard-less English society and narrates the title hero’s proto-Zionist mission to found a Jewish nation that re-establishes history, meaning and ethical values. This study attempts to trace the novel’s two models of society and time by bringing them into resonance with the myth of Narcissus and Echo famously rendered by Ovid. The unloving, self-referential, visual Narcissus is read as the model for the capitalistic world of spectacle and speculation. Echo’s loving, memory-bearing voice forms an important part in the construction of the sublating unity of the Jewish nation-to-come. Guided by this resonance between George Eliot’s novel and Ovid’s myth pieces of critical theory and philosophy are woven into the study’s fabric. The resulting analysis dissects and deconstructs the novel’s fascinating and highly complex patterns of conditions of possibility for the fabrication of the redeeming Jewish nation, the very same conditions that the novel presents as the conditions of possibility for narrating a meaningful story.

N2 - The World Health Organization designed OpenWHO.org to provide an inclusive and accessible online environment to equip learners across the globe with critical up-to-date information and to be able to effectively protect themselves in health emergencies. The platform thus focuses on the eXtended Massive Open Online Course (xMOOC) modality – contentfocused and expert-driven, one-to-many modelled, and self-paced for scalable learning. In this paper, we describe how OpenWHO utilized xMOOCs to reach mass audiences during the COVID-19 pandemic; the paper specifically examines the accessibility, language inclusivity and adaptability of hosted xMOOCs. As of February 2023, OpenWHO had 7.5 million enrolments across 200 xMOOCs on health emergency, epidemic, pandemic and other public health topics available across 65 languages, including 46 courses targeted for the COVID-19 pandemic. Our results suggest that the xMOOC modality allowed OpenWHO to expand learning during the pandemic to previously underrepresented groups, including women, participants ages 70 and older, and learners younger than age 20. The OpenWHO use case shows that xMOOCs should be considered when there is a need for massive knowledge transfer in health emergency situations, yet the approach should be context-specific according to the type of health emergency, targeted population and region. Our evidence also supports previous calls to put intervention elements that contribute to removing barriers to access at the core of learning and health information dissemination. Equity must be the fundamental principle and organizing criteria for public health work.

In the field of electrophysiology, the amplitude of the P300 component in event-related potentials (ERP) has been shown to be sensitive to the stimulus category (target vs. non target) of the eliciting stimulus, its overall probability, and the preceding stimulus sequence. In the present study we further specify the functional underpinnings of the prolonged microsaccadic inhibition in the visual oddball task, showing that the stimulus category, the frequency of a stimulus and the preceding stimulus sequence influence microsaccade rate. Furthermore, by co-recording ERPs and eye-movements, we were able to demonstrate that, despite being largely sensitive to the same experimental manipulation, the amplitude of P300 and the microsaccadic inhibition predict each other very weakly, and thus constitute two independent measures of the brain’s response to rare targets in the visual oddball paradigm.
