description: Am Ende der vierten Klasse verfügen 20% der Schülerinnen und Schüler in Schleswig-Holstein nur über basale mathematische Kompetenzen (Haag/ Roppelt 2012). Gleichzeitig ist bekannt, dass mathematische Fähigkeiten im Kindergarten oder bei der Einschulung die Mathematikleistung am Ende der Grundschulzeit relativ gut vorhersagen können (Krajewski/ Schneider 2006). Es erscheint deswegen sinnvoll, mit einer Förderung der mathematischen Kompetenzen möglichst früh zu beginnen. Dabei stellt sich die Frage, wie sich ein solches Förderprogramm möglichst wirksam implementieren lässt – auch vor dem Hintergrund, dass bis zu 40% der Grundschullehrkräfte in Schleswig-Holstein Mathematik unterrichten, ohne im Studium Grundlagen zur Mathematik und ihrer Didaktik gelernt zu haben (Stanat et al. 2012). Aus diesem Grund hat das Institut für Qualitätsentwicklung an Schulen in Schleswig-Holstein (IQSH) das Förderprogramm „Mathe macht stark – Grundschule“ entwickelt, implementiert und im Schuljahr 2013/2014 gemeinsam mit dem IPN Kiel eine Evaluationsstudie gestartet. Das Design der Evaluation und erste Ergebnisse werden in diesem Beitrag berichtet.

Our calculations are based on new continuum extrapolated lattice simulations using the 4stout staggered actions with a lattice resolution up to $N_t=16$. The simulation parameters are tuned such that the strangeness neutrality is maintained, as it is in heavy ion collisions.

description: Con el presente proyecto y desde una metodología cualitativa, se pretende dejar en evidencia una reflexión sobre los alcances y dificultades que se presentan en los procesos de atención que se le da a los casos de violencia intrafamiliar en la comisaría country desde la perspectiva de sus actores/as institucionales, busca analizar desde las misma percepciones de los funcionarios de la comisaría de familia zona centro que tan capacitados y apropiados están de la norma a la hora de brindar la atención, orientación y seguimiento a la personas que solicitan los servicios de la comisaría de familia. Denunciar un caso de violencia puede considerarse quizás el paso más importante para evitar su reincidencia y ponerle fin, pero también es importante velar porque los procesos no se estanquen y generar en la ciudadanía un sentimiento de desconfianza y rechazo a los mecanismos que buscan la defensa y protección de sus derechos.

description: Im Projekt CODI (COnceptual DIfficulties in the field of functional relationships) wurden typische Lernschwierigkeiten von Schülerinnen und Schülern im Bereich funktionaler Zusammenhänge erforscht. Hierzu wurde ein Diagnoseinstrument entwickelt, das typische Fehlermuster bei Darstellungswechseln zu linearen und quadratischen Funktionen erfasst. Dabei wurden, basierend auf den Ergebnissen des Projekts HEUREKO (vgl. Nitsch et al., 2014) der graphisch-algebraische (GA), der situativ-algebraische (SA) und der graphisch-situative (GS) Darstellungswechsel einbezogen. Fokussiert wurden Lernschwierigkeiten im Bereich des konzeptuellen Wissens, wobei Fehler als sichtbare Produkte von Lernschwierigkeiten aufgefasst wurden. Dabei wurden vorrangig systematische Fehler betrachtet, da bei diesen davon auszugehen ist, dass sie reproduzierbar sind und ihre Fehlerursache meist in stabilen falschen Konzepten bzw. sogenannten Fehlvorstellungen liegt (Führer, 1997). Für das Ziel der Diagnose von Lernschwierigkeiten wurden verschiedene charakterisierende Eigenschaften von Fehlvorstellungen aus bestehenden Konzeptualisierungen dieses Begriffs herausgearbeitet: Fehlvorstellungen treten wiederholt auf, sind robust gegenüber äußeren Einflüssen und über einen längeren Zeitraum stabil (z.B. Hammer, 1996; Leinhardt et al., 1990).

title: The Burnt-Tip Orchid (Neotinea ustulata), future restoration in Kent
Creators: name: Coles, Jacob M.
Publisher: name: University of Kent
Year: 2022

description: The Orchid species Neotinea ustulata is a small terrestrial species native across Europe, the populations found in the British Isles have been decline since the 1930's. As part of this decline the populations once found in the county of Kent have reduced to just one site in the past decade. The decline of this species is little understood and the drivers of it have only been speculated about in recent literature. This research aimed to assess two areas of concern for the species long-term viability, the effects of anthropogenic climate change on it's pollination phenology and the potential for pollinator decoupling and the public perception of the species to develop an understanding of the species within the funding landscape. The Best-Worst Scaling Type 3 questionnaire constructed and distributed indicated the species as being competitive from within the funding landscape within the context of other species found it its immediate habitat, calcareous grasslands. Scoring the highest proportion of the votes in five of the six choice experiments conducted among both relevant orchid and flora species found on calcareous grasslands. The pollination ecology of N. ustulata is little known in the British Isles with pollinating species only known from Germany. The known pollen vector for the subspecies var. ustulata (Leptura livida) is known from the British Isles whereas the pollen vector for var. aestivalis is not regularly reported from the British Isles. Potential pollen vectors for var. aestivalis in the British Isles were identified as Tachina grossa¸T. fera, T. ursina, and T. lurida. All pollen vectors showed a response to historic increases in springtime temperature of between 1.9 and 11.9 days earlier per ℃ increase in mean springtime temperature for peak flight dates. N. ustulata also showed the same response with a change of 4 days earlier per ℃ increase in mean springtime temperature. The findings of this thesis indicate the potential for positive community engagement with the conservation of N. ustulata as well as the potential risks to the pollution ecology of N. ustulata with advancing climate change

description: Neutrinos play a crucial role in many aspects of astrophysics and cosmology. Since they control the electron fraction, or equivalently neutron-to-proton ratio, neutrino properties impact yields of r-process nucleosynthesis. Similarly the weak decoupling temperature in the Big Bang Nucleosynthesis epoch is exponentially dependent on the neutron-to-proton ratio. In these conference proceedings, I briefly summarize some of the recent work exploring the role of neutrinos in astrophysics and cosmology.

description: A potentially serious ear infection can be managed better and severe complications avoided if physicians manage to diagnose it early enough and treat it properly, according to a new study by researchers in Qatar. Acute mastoiditis is a bacterial infection of the mastoid bones in the ear, which causes painful swelling and redness accompanied by fever, headaches and nausea. In severe cases, the infection spreads beyond the mastoid bones, leading to deafness, facial nerve paralysis, meningitis and intracranial and extracranial abscesses. The condition is relatively common in young children, but proper treatment leads to a full recovery in most cases. Shihab Mohammed Albaraznji of the Hamad Medical Corporation and his colleagues performed a retrospective study of 27 children aged 14 and under, all of whom had been admitted to paediatric emergency centres in Qatar between January 2005 and December 2008 and diagnosed with acute mastoiditis. More than three quarters of these patients presented with fever, and half of them reported ear pain. One developed an intracranial abscess that had to be surgically drained, but most of them began to improve within 2– 3 days from the start of an intravenous antibiotic drip, and recovered fully after hospital stays averaging 8.5 days in length. “A lot of physicians are aware of acute mastoiditis, especially paediatricians and ear, nose and throat doctors,” says Albaraznji, “but we still need to make others aware of how serious this disease can be if it isn’t diagnosed and treated properly.” Acute mastoiditis is associated with a number of different bacteria, but this study identified Pseudomonas aeruginosa as the most common one present in the patient sample. It also revealed that the incidence of acute mastoiditis is slightly higher in Qatar compared to several European countries. The findings highlight the need for early diagnosis and proper treatment in which the causative infectious agent is identified and the right antibiotic used to fight it. Such treatment can bring the infection under control before it spreads and causes more severe complications. “Awareness of the disease is the best thing for early diagnosis, in addition to proper treatment of acute otitis media with the correct antibiotics. At the same time we need to avoid overuse of antibiotics to avoid resistance,” says Albaraznji.

description: The use of hepatocyte cell lines as a replacement for animal models have been heavily criticised mainly due to low expression of metabolism enzymes. This study compares primary human hepatocytes with the C3A cell line and with respect to their response to a panel of nanomaterials (NMs; two ZnO, two MWCNTs, one Ag and one positively functionalised TiO2). The cell line was very comparable with the primary hepatocytes with regards to their cytotoxic response to the NMs (Ag > uncoated ZnO > coated ZnO). The LC50 was not attained in the presence of the MWCNTs and the TiO2 NMs. All NMs significantly increased IL-8 production, with no change in levels of TNF-α and IL-6. Albumin production was measured as an indicator of hepatic function. The authors found no change in levels of albumin with the exception of the coated ZnO NM at the LC50 concentration. NM uptake was similar for both the primary hepatocytes and C3A cells as investigated by TEM. Meanwhile, the authors confirmed greater levels of CYP450 activity in untreated primary cells. This study demonstrates that the C3A cell line is a good model for investigating NM-induced hepatocyte responses with respect to uptake, cytotoxicity, pro-inflammatory cytokine production and albumin production.
(De-)Zentralisierung von Entscheidungen in globalen Produktionsnetzwerken - Strategie- und komplexitätsorientierte Gestaltung der Entscheidungsautonomie

description: Unternehmen unterschiedlicher Größe und Branche dezentralisieren ihre Produktion geografisch in globalen Produktionsnetzwerken. Globale Produktionsnetzwerke bieten verschiedene Möglichkeiten Wettbewerbsvorteile auszuschöpfen. Den Produktionsstandorten in diesen Netzwerken kann eine hohe oder niedrige Entscheidungsautonomie bzgl. produktionsrelevanter Entscheidungen eingeräumt werden. Eine hohe Entscheidungsautonomie von Produktionsstandorten kann zu einer besseren Anpassung an lokale Markterfordernisse führen, während eine geringe Entscheidungsautonomie Kosten- und Standardisierungsvorteile für das Produktionsnetzwerk fördern kann. Der ideale Grad an Entscheidungsautonomie hängt von verschiedenen Einflussfaktoren wie dem Umfeld des Produktionsnetzwerks, der internen Struktur und der Strategie ab. Die Digitalisierung und die Organisationsstruktur des Produktionsnetzwerks können als Enabler fungieren, um die (De-)Zentralisierung von Entscheidungen zu unterstützen. Im aktuellen Stand der Forschung liegen vielfältige Ansätze zur (De-)Zentralisierung von Entscheidungen aus Standortperspektive vor. Vernachlässigt wird eine Analyse auf Netzwerkebene. Ebenso sind der Einfluss der Strategie und der Komplexität auf die (De-)Zentralisierung von Entscheidungen nicht umfänglich erforscht. Es fehlt zudem eine Methodik, die Unternehmen dabei unterstützt, die ideale (De-)Zentralisierung von Entscheidungen für ihr Produktionsnetzwerk zu identifizieren und zu erreichen. Ausgehend von der Motivation und dem Literaturdefizit leistet diese Arbeit einen Beitrag zum Themenfeld der (De-)Zentralisierung von Entscheidungen in globalen Produktionsnetzwerken. Auf der Grundlage einer quantitativen Benchmarkingstudie werden mittels einer Clusteranalyse unterschiedliche Formen der (De-)Zentralisierung von Entscheidungen in globalen Produktionsnetzwerken identifiziert. Darauf aufbauend werden Wirkzusammenhänge zwischen den Dimensionen der Strategie, der Komplexität, der (De-)Zentralisierung von Entscheidungen und der Leistungsfähigkeit bzw. den Netzwerkfähigkeiten mittels Regressionsanalysen untersucht. Diese Erkenntnisse werden in eine Methodik zur strategie- und komplexitätsorientierten Gestaltung der Entscheidungsautonomie bzw. der (De-)Zentralisierung von Entscheidungen implementiert. Die entwickelte Methodik wird exemplarisch auf zwei Anwendungsfälle aus der Elektronik- und Automobilzuliefererindustrie angewandt. Die Ergebnisse zeigen, dass die Methodik den strategischen Fit in globalen Produktionsnetzwerken verbessert und das Management von globalen Produktionsnetzwerken unterstützt.

description: Background: Carbon nanotubes (CNT) are fibre-like nanomaterials whose structural similarity to asbestos has raised concerns that they may also pose a mesothelioma hazard. The objective of this study was to examine the inflammatory potential of three CNT samples of differing length on the lungs and pleural cavity following introduction into the airspaces of mice. ResultsAspiration of the two short/tangled and one long CNT sample into the lungs of mice resulted in a length-dependent inflammatory response at 1 week, i.e., only the long CNT sample caused acute neutrophilic inflammation in bronchoalveolar lavage at 1 week and progressive thickening of the alveolar septa. The authors also report length-dependent inflammatory responses in the pleural lavage after exposure only to the long CNT. The inflammatory response in the pleural cavity to long fibres and the appearance of lesions along the chest wall and diaphragm was not present at 1 week and only evident by 6 weeks post-exposure. Conclusion: Length-dependent pathogenicity is a feature of asbestos and the results presented in this study demonstrate similar length-dependent pathogenicity of CNT in the lungs and pleural space following airspace deposition. The data support the contention that long CNT reach the pleura from the airspaces, and that they are retained at the parietal pleura and cause inflammation and lesion development. The parietal pleura is the site of origin of mesothelioma and inflammation is considered to be a process involved in asbestos carcinogenesis and so the data support the contention that CNT may pose an asbestos-like mesothelioma hazard.

description: Matrix product states (MPS) illustrate the suitability of tensor networks for the description of interacting many-body systems: ground states of gapped $1$-D systems are approximable by MPS as shown by Hastings [J. Stat. Mech. Theor. Exp., P08024 (2007)]. In contrast, whether MPS and more general tensor networks can accurately reproduce correlations in critical quantum systems, respectively quantum field theories, has not been established rigorously. Ample evidence exists: entropic considerations provide restrictions on the form of suitable Ansatz states, and numerical studies show that certain tensor networks can indeed approximate the associated correlation functions. Here we provide a complete positive answer to this question in the case of MPS and $2D$ conformal field theory: we give quantitative estimates for the approximation error when approximating correlation functions by MPS. Our work is constructive and yields an explicit MPS, thus providing both suitable initial values as well as a rigorous justification of variational methods.

description: Humans and the environment can come into contact with nanomaterials through a wide range of applications during all stages of the life cycle of nanoproducts. The aim of this commentary is to present an assessment of the potential for exposure and thus identify possible environmental, health and safety (EHS) issues for nanomaterials used in 10 technology sectors. We analysed all life cycle stages with regard to potential for exposure of workers, consumers/patients, and the environment. A wide variety of nanomaterials are used of which many have negligible potential for exposure, while others have medium or even high potential for exposure. Based on the likelihood of exposure, it appears that in general most attention should be paid to the agrifood, chemistry/materials, textiles and health sectors; and less to the information and communication technology (ICT), security and energy sectors. Toxicity and exposure are both important; however, the EHS impact of nanomaterials is always dependent on their particular use.

description: Saturn's moon Enceladus offers a unique opportunity in the search for life and habitable environments beyond Earth, a key theme of the National Research Council's 2013-2022 Decadal Survey. A plume of water vapor and ice spews from Enceladus's south polar region. Cassini data suggest that this plume, sourced by a liquid reservoir beneath the moon's icy crust, contain organics, salts, and water-rock interaction derivatives. Thus, the ingredients for life as we know it-- liquid water, chemistry, and energy sources-- are available in Enceladus's subsurface ocean. We have only to sample the plumes to investigate this hidden ocean environment. We present a New Frontiers class, solar-powered Enceladus orbiter that would take advantage of this opportunity, Testing the Habitability of Enceladus's Ocean (THEO). Developed by the 2015 Jet Propulsion Laboratory Planetary Science Summer School student participants under the guidance of TeamX, this mission concept includes remote sensing and in situ analyses with a mass spectrometer, a sub-mm radiometer-spectrometer, a camera, and two magnetometers. These instruments were selected to address four key questions for ascertaining the habitability of Enceladus's ocean within the context of the moon's geological activity: (1) How are the plumes and ocean connected? (2) Are the abiotic conditions of the ocean suitable for habitability? (3) How stable is the ocean environment? (4) Is there evidence of biological processes? By taking advantage of the opportunity Enceladus's plumes offer, THEO represents a viable, solar-powered option for exploring a potentially habitable ocean world of the outer solar system.

description: Aquatic toxicology of engineered nanoparticles is challenged by methodological difficulties stemming partly from highly dynamic and poorly understood behavior of nanoparticles in biological test systems. In this paper scientific and technical challenges of testing not readily soluble nanoparticles in standardised algal growth inhibition tests are highlighted with specific focus on biomass quantification methods. This is illustrated through tests with TiO2 and Au nanoparticles, for which cell-nanoparticle interactions and behavior was studied during incubation. Au NP coating layers changed over time and TiO2 nanoparticle aggregation/agglomeration increased as a function of concentration. Three biomass surrogate measuring techniques were evaluated (coulter counting, cell counting in haemocytometer, and fluorescence of pigment extracts) and out of these the fluorometric methods was found to be most suitable. Background correction was identified as a key issue for biomass quantification, complicated by algae-particle interactions and nanoparticle transformation. Optimisation of the method is needed to reduce further particle interference on measurements.

description: Older adults with amnestic mild cognitive impairment (aMCI) who in addition to their memory deficits also suffer from frontal-executive dysfunctions have a higher risk of developing dementia later in their lives than older adults with aMCI without executive deficits and older adults with non-amnestic MCI (naMCI). Handgrip strength (HGS) is also correlated with the risk of cognitive decline in the elderly. Hence, the current study aimed to investigate the associations between HGS and executive functioning in individuals with aMCI, naMCI and healthy controls. Older, right-handed adults with amnestic MCI (aMCI), non-amnestic MCI (naMCI), and healthy controls (HC) conducted a handgrip strength measurement via a handheld dynamometer. Executive functions were assessed with the Trail Making Test (TMT A&B). Normalized handgrip strength (nHGS, normalized to Body Mass Index (BMI)) was calculated and its associations with executive functions (operationalized through z-scores of TMT B/A ratio) were investigated through partial correlation analyses (i.e., accounting for age, sex, and severity of depressive symptoms). A positive and low-to-moderate correlation between right nHGS (rp (22) = 0.364; p = 0.063) and left nHGS (rp (22) = 0.420; p = 0.037) and executive functioning in older adults with aMCI but not in naMCI or HC was observed. Our results suggest that higher levels of nHGS are linked to better executive functioning in aMCI but not naMCI and HC. This relationship is perhaps driven by alterations in the integrity of the hippocampal-prefrontal network occurring in older adults with aMCI. Further research is needed to provide empirical evidence for this assumption.

description: [Abstract] 

As a social reformer, Elizabeth Denby focused her professional life on proposing new housing schemes to rehouse people from slums and on the development of collective housing for the working class. 

As part of a group of women studying the configuration of domestic space and its relationship with gender, she developed different project strategies that materialised in Kensal House. Through the functional design of the kitchens and the integration of intermediate and collective spaces in the dwellings, she pursues the objective of influencing the development of society and the shaping of a community. 

This work attempts to analyse the relationship and validity of hers ideas with respect to the needs of contemporary living. The common denominator of the research is the following reflection: is it possible for the design of domestic space to contribute to the configuration of a community? 
description: [Resumen] 

Elizabeth Denby, como reformadora social, centrará su vida profesional en proponer nuevos planes de vivienda para realojar a personas procedentes de barrios marginales, así como en el desarrollo de vivienda colectiva para la clase obrera. 

Formando parte de un conjunto de mujeres que estudian la configuración del espacio doméstico y su relación con el género, desarrolla distintas estrategias de proyecto que se materializan en Kensal House. A través del diseño funcional de las cocinas y de la integración de espacios intermedios y colectivos en las viviendas, persigue el objetivo de influir en el desarrollo de la sociedad y en la conformación de una comunidad. 

Este trabajo trata de analizar la relación y vigencia de sus ideas con respecto a las necesidades del habitar contemporáneo. Como denominador común de la investigación se plantea la siguiente reflexión: ¿es posible que el diseño del espacio doméstico contribuya en la configuración de una comunidad?
title: Das narrative Potenzial nichtdiegetischer Klänge im Film - Eine Analyse akusmatischer Geräusche anhand ausgewählter Filmszenen seit den 1970er Jahren

description: Die vorliegende Bachelor-Thesis stellt die Frage in den Fokus, ob nichtdiegetischen Klängen im Film eine ausreichende Semantik innewohnt, sodass sie eine narrative Funktion übernehmen können. Um sich dem Untersuchungsgegenstand zu nähern, werden für die Analyse essenzielle Begrifflichkeiten erläutert und für diese Arbeit gültige Definitionen aufgestellt. An den theoretischen Teil anknüpfend, erfolgt eine Vorstellung ausgewählter Geräusche und ihre kultur- sowie sozialhistorische Bedeutung. Wenn man versteht, ob die Bedeutung eines Klangobjekts durch einen weiteren Kontext angereichert ist, lässt dies die Einordnung und Interpretation einer narrativen Semantik von gegebenenfalls nichtdiegetischen Geräuschen zu. Mittels selektierter Filmbeispiele seit den 1970er-Jahren wird überprüft, ob und in welchem Umfang in der bisherigen Sounddesign-Praxis dieser Erzählweise Beachtung geschenkt wurde. Die Analysen werden dabei die Anforderungen an ein Geräusch und dessen Setzung offenbaren, die notwendig sind, damit ein semantischer Gehalt gegeben ist. Abschließend wird erläutert, wie der narrative Einsatz nichtdiegetischer Klänge die konzeptionellen Überlegungen und das Sounddesign des studentischen Films Ich geh nirgendwohin, für dessen Bildmontage und Tongestaltung der Autor dieser Thesis verantwortlich ist, beeinflusst hat.
description: The present bachelor thesis focuses on the question of whether non-diegetic sounds in film sufficient semantics have so that they can assume a narrative function. In order to get closer to the subject of research, essential terms for the analysis are explained and definitions that are valid for this work are established. Following on from the theoretical part, selected sounds and their cultural and socio-historical significance are presented. Understanding whether the meaning of a sound object is enriched by a larger context enables the classification and interpretation of the narrative semantics of possibly nondiegetic sounds. Using selected film examples since the 1970s, it is checked whether the previous sound design practice paid attention to this narrative method, in which contexts it is used and whether it is a common stylistic device. The analyzes will show the requirements for a sound and its positioning, which are necessary to ensure that semantic content is given. Finally, it is explained how the narrative use of non-diegetic sounds has influenced the conceptual considerations and the sound design of the student film I won’t go anywhere, for the film editing and sound design of which the author of this work is responsible.

description: We want to characterize the dynamical state of galaxy clusters detected with the Sunyaev-Zeldovich (SZ) effect by Planck and compare them with the dynamical state of clusters selected in X-rays survey. We analyzed a representative subsample of the Planck SZ catalogue, containing the 132 clusters with the highest signal to noise ratio and characterize their dynamical state using as indicator the projected offset between the peak of the X-ray emission and the position of the Brightest cluster galaxy. We study the distribution of our indicator in our sample and compare it to its distribution in X-ray selected samples (HIFLUGCS, MACS and REXCESS). The distributions are significantly different and the fraction of relaxed objects is smaller in the Planck sample ($52 \pm 4 \%$) than in X-ray samples ($\simeq 74\%$) We interpret this result as an indication of different selection effects affecting X-rays (e.g. "cool core bias") and SZ surveys of galaxy clusters.
