Zur Nutzung des Bilanzanalyse-Systems MIDIAS im Branchenvergleich: Eine Dokumentation am Beispiel der Bekleidungsindustrie

Im Rahmen eines Praktikums zur computergestützten Unternehmensanalyse wurden im Sommersemester 1990 am Lehrstuhl für Organisation mit Hilfe des Datev-Proprammes MIDIAS die Jahresabschlüsse von 18 Unternehmen der Bekleidungsindustrie untersucht. Ziel dieser Analyse war es, anhand von Einzelanalysen Kennzahlen abzuleiten, die über die gesamte Unternehmensstichprobe in der Lage waren, erfolgreiche Unternehmen von weniger erfolgreichen signifikant zu unterscheiden. Die Untersuchung wurde bewußt auf die Unternehmen einer Branche beschränkt, um auch die häufig vernachlässigten Kennzahlen der güter- und leistungswirtschaftlichen, operativen Unternehmensbereiche in das Analysedesign aufnehmen zu können. Die Erkenntnisse aus der Einzelbetrachtung der Jahresabschlüsse wurden dann in einem zweiten Schritt durch statistische Kennzahlenauswertungen über die gesamte Stichprobe geprüft

Innovative 3D Model of the Human Middle Ear in High Resolution with a Histological Microgrinding Method: A Feasibility Study and Comparison with μCT

Conclusion. The development of a histological 3D model of the tympanic cavity visualizes the exact microanatomy of the sound conduction organ and is therefore essential for finite elements simulations and surgical training. Objectives. So far, no accurate histological 3D model of the sound conduction system existed in literature. For 3D reconstruction of the very fine structures inside and outside the auditory ossicles, a method based on histological slices allows a more differential analysis of both hard and soft tissues and could thus be superior to μCT. Method. A complete temporal bone was embedded in epoxy resin and microground in distances of about 34 μm. After photodocumentation of every plane, a 3D reconstruction was performed by using the Computer Aided Design (CAD) program Rhinoceros 5®. For comparison, a μCT of the same specimen resulted in a 3D model of the calcified structures in the middle ear. Results. The histological 3D model gives an excellent overview to all anatomical soft and bony tissues of the human auditory ossicles. Specifically the fine blood vessel system and the exact dimension of cartilage areas inside the ossicles can be illustrated much more precisely than with μCT data. The present technique also allows the evaluation of the fine connecting ligaments inside the tympanic cavity

dolls/puppets in threat scenarios

Puppen in Bedrohungsszenarien – so lautet der Themenschwerpunkt der ersten Ausgabe der interdisziplinären online-Zeitschrift "denkste: puppe / just a bit of: doll" zu Mensch-Puppen-Diskursen (Akronym: de:do). Die Bezeichnung ‚Puppe’ steht dabei für anthropomorphe ,Wesen’ und Artefakte in all ihren unterschiedlichen Erscheinungsformen und der Begriff der Bedrohung wird hier weit gefasst. Ausgangspunkt der Entscheidung für diesen Fokus war die Annahme, dass Puppen und puppenaffinen Artefakten sowohl in Zeiten existenzieller Bedrohung als auch in Phasen innerpsychischer Beunruhigung und Irritation eine besondere Bedeutung zukommt. Die hier einbezogenen Beiträge stammen aus unterschiedlichen Fachdisziplinen und eröffnen in der bewusst nicht disziplinär ausgerichteten Zusammenstellung reizvolle multiperspektivische Mensch-Puppen-Diskurse. Dabei sind nicht nur die hier angesprochenen Themenbezüge, sondern auch die jeweiligen methodischen Zugänge ausgesprochen heterogen. So werden Puppen-Narrative aufgegriffen, die beispielsweise innerhalb der Literaturwissenschaft an die lange Tradition von Puppen-Erzählungen anknüpfen, aber auch solche, die aktuell in den Diskursen über Zukunftsszenarien und neue Technologien mittels verschiedener medialer Formate und/oder künstlerischer Aktionen für Diskussionsstoff sorgen. Ein erster thematischer Fokus liegt auf der Bedeutung von Puppen im Zuge der Erfahrung von Bedrohung und Verlusten im Kontext von Krieg, Flucht und Verfolgung in politisch unsicheren Zeiten. Hier werden aus verschiedenen fachdisziplinären Perspektiven unterschiedliche Facetten von Bedrohungsszenarien angesprochen. So geht es aus theaterwissenschaftlicher Sicht um zwei Inszenierungen aus dem Bereich des Objekt- und Materialtheaters, in denen bedrohliche Kriegsdarstellungen mittels Plastikpuppen bzw. amorphen Materials aufbereitet werden. Aus psychologischer Perspektive kommen Rollen und Funktionen von Puppen als Übergangsobjekte im Kontext von Umbrüchen, Krieg und Gewalt zur Sprache. In zwei literaturwissenschaftlichen Beiträgen wird jeweils ein Roman aus der Kinder- und Jugendliteratur analysiert, in denen in einem Fall eine Puppe zur psychischen Stabilisierung der literarischen Protagonistin beiträgt und im anderen Fall das Schicksal der Puppe die Geschichte von Abschied und letztendlicher Vernichtung ihrer Besitzerin erzählt und symbolisiert. Und schließlich geht es um den Stellenwert von Puppen und Teddys in verschiedenen Kinderzeitschriften, die – in den politisch unsicheren Zeiten zwischen und nach den beiden Weltkriegen – Identifikationsfiguren und Interaktionspartner für Kinder sein können. Ein zweiter Fokus thematisiert Puppen und ihre Narrative im Kontext verschiedener aversiver Erfahrungen sowie in Zeiten psychischer Irritation. So geht es zum einen um die literaturwissenschaftliche Sicht auf die Bedeutung und Wirkung von Puppen in zwei ‚klassischen’ Puppenerzählungen: „"Nussknacker und Mausekönig" von E.T.A. Hoffmann und "Romeo und Julia auf dem Dorfe" von Gottfried Keller. Zum anderen werden in verschiedenen Beiträgen Entgrenzungs-, Transformations- und Identitätsfragen in Mensch-Puppen-Bezügen aus medien- und kunstwissenschaftlicher sowie kinderliterarischer Perspektive angesprochen, in denen Puppen in Gestalt von Androiden, Kunstwesen oder anthropomorphen Figuren agieren und dabei selber Irritationen auslösen oder Versuche darstellen, Antworten auf beunruhigende Fragen zu finden. Über den Themenschwerpunkt hinaus finden sich zudem eine Reihe weiterer Beitragsformen zu verschiedenen puppenbezogenen Themen und Praxen, die noch einmal das breite Spektrum unterschiedlicher Puppen-Narrative und Zugangsformen dokumentieren: So beschäftigt sich ein freier Beitrag mit dem Puppenspiel als strukturiertes Therapieangebot für Kinder, bei den Miszellen findet sich eine Skizze zu Marlene Dietrich und ihren Puppen sowie ein kurzer Essay zu einer biographischen Erinnerung, ein Interview mit der Begründerin des Berliner Puppentheaters bubales veranschaulicht Möglichkeiten der dramatischen und poetischen Umsetzung von Puppen-Themen, im Diskussionsforum wird ein kritischer Blick auf "Barbie als Diskursmaschine" geworfen und eine Rezension zum Ausstellungskatalog "From Her Wooden Sleep von Ydessa Hendels" lotet Chancen und Grenzen der künstlerischen Arbeit mit Puppen-Artefakten aus.Dolls / Puppets in Threat Scenarios – this is the topic focus of the first issue of the interdisciplinary online magazine "denkste: puppe / just a bit of: doll" on human-doll discourses (acronym: de: do). The term ’doll’ stands for anthropomorphic ’beings’ and artifacts of all kinds and the concept of threat is broadly defined. This focus was stimulated by the assumption that dolls and doll-related artifacts are of particular importance in times of existential threat as well as in phases of inner psychic anxiety and irritation. Yet, the basically ambiguous character of the doll does not necessarily determine a clear effect, so that its usability always involves a certain blurriness and ambivalence. In threatening and adverse situations dolls can act as companions and significant (transitional) objects, thus allowing psychic stabilization, security, and attachment as well as enabling (inner) autonomy, agency, and developmental processes. But dolls can also be a crucial component of threat scenarios themselves and act frightening in this function. All this applies not only to material and real existing dolls and puppets, but also to dolls as literary and / or media figures as well as to doll narratives of any kind. The articles included here come from different disciplines and open up an appealing and deliberately non-disciplinary oriented human-doll discourse from multiple perspectives. Accordingly, the relevant themes as well as the respective methodological approaches are highly heterogeneous. Thus, some contributions follow the long tradition of doll narratives in literature while others discuss currrent topics and discourses on future scenarios and new technologies by means of various doll-related media formats and / or art performances. A first thematic focus is on the significance of dolls in experiencing threats and losses in the context of war, flight and persecution in times of political uncertainty. Here, different facets of threat scenarios are addressed from different disciplinary perspectives. From the field of object and material theater two productions are introduced in which menacing war scenes are processed by means of plastic dolls or amorphous material. From a psychological perspective, dolls are discussed in their roles and functions as transitional objects within the context of upheaval, war and violence. Furthermore, two literary contributions analyze novels from children’s and youth literature. One story deals with a doll which contributes to the psychological stabilization of the literary protagonist. The other story tells of a girl and her doll which symbolizes the final farewell and eventual annihilation of the (Jewish) girl. Finally, the role of dolls and teddy bears in various children’s magazines is exemplified, which serve as identification figures and interaction partners for children in the politically unstable times between and after the two World Wars. A second focus deals with dolls and their narratives in the context of various aversive experiences as well as in times of psychological irritation. Two contributions analyze the meaning and effect of dolls in two ’classical’ doll narratives from a literary perspective: "Nussknacker und Mausekönig" by E.T.A. Hoffmann and "Romeo und Julia auf dem Dorfe" by Gottfried Keller. Further contributions address questions of ego dissolution, transformation and identity processes in human-doll relations from various perspectives such as media, art and children’s literature. Here, dolls appear as androids, artistic or anthropomorphic figures which cause irritation themselves or attempt to find answers to disturbing human-doll questions. In addition to the main topic, there are also a number of other sections and types of contributions on various doll-related topics and practices which once again document the wide range of doll narratives and possible forms of access: For example, a free contribution deals with doll play as a structured therapy for children, the miscellaneous section includes a portrait of Marlene Dietrich and her dolls as well as a short essay on a biographical reminiscence, an interview with the founder of the Berlin Puppet Theater bubales illustrates the possibilities of dramatic and poetic realization of puppet and doll narratives, a critical view on "Barbie as a discourse machine" is presented in the discussion forum and a review of the exhibition catalog "From Her Wooden Sleep by Ydessa Hendels" explores opportunities and limits of artistic work with doll artifacts

Anticoagulation with edoxaban in patients with long Atrial High-Rate Episodes ≥24 hours

BACKGROUND AND AIMS: Patients with long atrial high-rate episodes (AHRE) ≥ 24 hours and stroke risk factors are often treated with anticoagulation for stroke prevention. Anticoagulation has never been compared to no anticoagulation in these patients.METHODS: This secondary prespecified analysis of NOAH-AFNET 6 examined interactions between AHRE duration at baseline and anticoagulation with edoxaban compared to placebo in patients with AHRE and stroke risk factors. The primary efficacy outcome was a composite of stroke, systemic embolism, or cardiovascular death. The safety outcome was a composite of major bleeding and death. Key secondary outcomes were components of these outcomes and ECG-diagnosed atrial fibrillation.RESULTS: AHRE ≥24 hours were present at baseline in 259/2389 patients enrolled in NOAH-AFNET 6 (11%, 78 ± 7 years old, 28% women, CHA2DS2-VASc score 4). Clinical characteristics were not different from patients with shorter AHRE. During a median follow-up of 1.8 years, the primary outcome occurred in 9/132 patients with AHRE ≥24 hours (4.3%/patient-year, 2 strokes) treated with anticoagulation and in 14/127 patients treated with placebo (6.9%/patient-year, 2 strokes). AHRE duration did not interact with the efficacy (p-interaction = 0.65) or safety (p-interaction = 0.98) of anticoagulation. Analyses including AHRE as a continuous parameter confirmed this. Patients with AHRE ≥24 hours developed more ECG-diagnosed atrial fibrillation (17.0%/patient-year) than patients with shorter AHRE (8.2%/patient-year; p &lt; 0.001).CONCLUSIONS: This hypothesis-generating analysis does not find an interaction between AHRE duration and anticoagulation therapy in patients with device-detected AHRE and stroke risk factors. Further research is needed to identify patients with long AHRE at high stroke risk.</p

Peanut‐induced anaphylaxis in children and adolescents: Data from the European Anaphylaxis Registry

Background Peanut allergy has a rising prevalence in high-income countries, affecting 0.5%-1.4% of children. This study aimed to better understand peanut anaphylaxis in comparison to anaphylaxis to other food triggers in European children and adolescents. Methods Data was sourced from the European Anaphylaxis Registry via an online questionnaire, after in-depth review of food-induced anaphylaxis cases in a tertiary paediatric allergy centre. Results 3514 cases of food anaphylaxis were reported between July 2007 - March 2018, 56% in patients younger than 18 years. Peanut anaphylaxis was recorded in 459 children and adolescents (85% of all peanut anaphylaxis cases). Previous reactions (42% vs. 38%; p = .001), asthma comorbidity (47% vs. 35%; p < .001), relevant cofactors (29% vs. 22%; p = .004) and biphasic reactions (10% vs. 4%; p = .001) were more commonly reported in peanut anaphylaxis. Most cases were labelled as severe anaphylaxis (Ring&Messmer grade III 65% vs. 56% and grade IV 1.1% vs. 0.9%; p = .001). Self-administration of intramuscular adrenaline was low (17% vs. 15%), professional adrenaline administration was higher in non-peanut food anaphylaxis (34% vs. 26%; p = .003). Hospitalization was higher for peanut anaphylaxis (67% vs. 54%; p = .004). Conclusions The European Anaphylaxis Registry data confirmed peanut as one of the major causes of severe, potentially life-threatening allergic reactions in European children, with some characteristic features e.g., presence of asthma comorbidity and increased rate of biphasic reactions. Usage of intramuscular adrenaline as first-line treatment is low and needs to be improved. The Registry, designed as the largest database on anaphylaxis, allows continuous assessment of this condition

Impact and Lessons Learned from a National Consortium for Participatory Health Research: PartKommPlus—German Research Consortium for Healthy Communities (2015–2018)

Integrated strategies of health promotion at the municipal level are receiving particular attention in public health policy and practice in Germany. These strategies are intended to provide a coordinated approach to health promotion during the entire lifespan, with a particular focus on vulnerable communities. They are also intended to be participatory in both their design and implementation, involving all sectors of the social welfare, educational and healthcare systems, civil society, and the general public. PartKommPlus—German Research Consortium for Healthy Communities is examining such strategies using participatory forms of research. The goal is to determine how participation can best be planned and implemented and what effects this participation has. In this article the work of PartKommPlus from the first funding phase (2015–2018) will be described with particular attention to the lessons learned and the forms of impact which are being considered as part of the participatory research process.Peer Reviewe

Rollen und Rollendynamiken in der partizipativen Forschungsgemeinschaft

The participatory research approach results in changes in roles and relationships for researchers and coresearchers compared to traditional research concepts. In the form of a workshop report, this article describes reflections and findings on the question of how roles are perceived and filled in participatory health research (PHR). Researchers and practitioners from two subprojects in the research consortium PartKommPlus evaluated their experiences from several years of cooperation and developed insights into which dynamics were important for the design of roles and what should be considered for a productive development of roles.Five important elements were identified: the significance of the scope for action resulting from the ties of the participants to their respective institutions; the change of roles and relationships over the course of the project time; the significance of trust for functioning cooperative relationships; the problem of information confidentiality for scientific exploitation; and the political character of the cooperation, which is based on the claim for change of participatory research and which presupposes shared basic attitudes and goals. Finally, the importance of joint reflection on role design, which contributes to the success or failure of participatory research cooperation and the quality of its results, is highlighted

Development of a test procedure for concrete according to XF2-exposition

Ziel des Vorhabens war es, ausgehend von dem für XF4-Betone anerkannten CDF-Prüfverfahren ein Laborprüfverfahren zu entwickeln, das einen abgeschwächten Frost-Tausalzangriff gemäß XF2-Exposition erzeugt und eine Beurteilung des Frost-Tausalzwiderstandes bei mäßiger Sättigung zulässt. Die am IBPM der Universität Duisburg-Essen durchgeführten Laborergebnisse verdeutlichen, dass eine Beurteilung des Widerstandes gegenüber einer XF2-Exposition über die Einstellung eines mäßigeren Feuchtegehaltes beziehungsweise Sättigungsgrades nicht eindeutig möglich ist. Dagegen ergab die Kombination der drei Prüfparameter - Minimaltemperatur "10-°C, 3%ige NaCl-Lösung und 14 FTW Prüfdauer - eine geeignete Abschwächung des CDF-Prüfverfahrens auf die Erfordernisse von XF2-Mischungen. Aufgrund der geringen Datenmenge ließ sich jedoch noch kein allgemein gültiger Grenzwert als Abnahmekriterium festlegen. Im Rahmen der Untersuchungen am cbm der TU München wurden Betone, die aufgrund ihrer Zusammensetzung für die Klassen XF4 und XF2 beziehungsweise für geringere Klassen als XF2 geeignet sind, sowohl durch Untersuchungen im Labor als auch durch Auslagerungsversuche beurteilt. Anhand der durch Auslagerung ermittelten Feuchtedaten wird deutlich, dass die Schädigung über die verschiedenen Winterperioden kumulativ zu sehen ist und nicht aus einer zunehmenden Sättigung des gesamten Probekörpers über mehrere Winter hinweg resultiert. Die Schädigung ist die Folge einer lokalen Übersättigung der äußersten Randzone, die jedoch weder durch Wägung des gesamten Probekörpers noch durch Messungen mit der Multiringelektrode erfassen werden konnte. Die Aufsättigung des Zementsteingefüges erfolgt bei Außenbauteilen aufgrund sich ändernder thermischer Randbedingungen und des damit verbundenen dynamischen Prozesses scheinbar in einer geringeren Schichtdicke als beim CDF-Verfahren. Folglich entstehen in der Praxis trotz vergleichbarer Anzahl an Frost-Tau-Wechseln geringere Schädigungen. Unabhängig davon erwies sich die Korrelation der Schädigung im Labortest und in der Praxis als sehr gut. Der modifizierte CDF-Test mit einer reduzierten Prüfdauer von 14 Frost-Tau-Wechseln und einer Minimaltemperatur von "10-°C spiegelt das Verhalten von XF2 Betonen praxisgerecht wieder.he aim of this project was to develop a laboratory test procedure for XF4-concrete based on the accepted CDF-test procedure which produces a reduced frost-thaw attack according to XF-2 exposition and an assessment of the frost-thaw-resistance at a moderate saturation. The laboratory results achieved at the IBPM, university Duisburg-Essen show that an evaluation of the resistance compared to the XF2-exposition my means of the calibration of a moderate moisture that means saturation is not clearly possible. However, the combination of three test parameter " minimal temperature "10-°C, 3% NaCl-solution and 14 days frost-thaw-cycles resulted in an appropriate mitigation of the CDF-test procedure with the regard to the demand of XF-2 mixtures. On the basis of a minor amount of data no general boundary value could be determined as acceptance criteria. In line with the tests at the cbm of the Technical University Munich concrete were tested which were suitable on the basis of their consistency for the specification XF4 and XF2 that means for minor specifications such a XF2 both by laboratory or by field tests. Moisture data which were obtained by field tests show that the damage during various winter periods is cumulative which does not result in an increasing saturation of the whole specimen over several winter periods. The damage is a result of a local oversaturation of the outermost peripheral zone which could not be recorded neither by weighting of the whole specimen nor by measuring with the multi-ring-electrode. The saturation of the hardened cement paste structure occurs at outer constructional elements due to changing thermal boundary conditions and its dynamic process obviously in a smaller layer thickness than at the CDF-process. Consequently smaller damage occurs in practice despite a comparable number of frost-thaw-cycles. Despite that the correlation of damage under laboratory test conditions and in practice proved to be very good. The modified CDF-test reflects the behaviour of XF2 concrete in practice with a reduced test duration of 14 frost-thaw-changes and a minimum temperate of "10-°C

Photovoice as a participatory method: impacts on the individual, community and societal levels

We present the visual data collection method called “photovoice” in participatory research, and discuss its impetus for change and its possible impacts on work with different groups of people. Using three case examples from PartKommPlus – Research Consortium for Healthy Communities, we report our experiences from joint research involving adults with learning difficulties and young people. Following the Photovoice Impact Model of CATALANI and MINKLER (2010), we assigned the observed impacts to three categories: the individual, community and societal levels. In line with the model, we discuss the contribution that the photovoice method can make to the individual empowerment of co-researchers, the understanding of community needs and assets, and to changing social reality by influencing political and other key actors

Rotating thermal convection in liquid gallium: multi-modal flow, absent steady columns

Earth’s magnetic field is generated by convective motions in its liquid metal core. In this fluid, the heat diffuses significantly more than momentum, and thus the Prandtl number $Pr$ is well below unity. The thermally driven convective flow dynamics of liquid metals are very different from moderate-$Pr$ fluids, such as water and those used in current dynamo simulations. In order to characterise rapidly rotating thermal convection in low-$Pr$ number fluids, we have performed laboratory experiments in a cylinder of aspect ratio \unicode[STIX]{x1D6E4}=1.94 using liquid gallium ($Pr\simeq 0.025$) as the working fluid. The Ekman number varies from $E\simeq 5\times 10^{-6}$ to $5\times 10^{-5}$ and the Rayleigh number varies from $Ra\simeq 2\times 10^{5}$ to $1.5\times 10^{7}$. Using spectral analysis stemming from point-wise temperature measurements within the fluid and measurements of the Nusselt number $Nu$, we characterise the different styles of low-$Pr$ rotating convective flow. The convection threshold is first overcome in the form of container-scale inertial oscillatory modes. At stronger forcing, sidewall-attached modes are identified for the first time in liquid metal laboratory experiments. These wall modes coexist with the bulk oscillatory modes. At $Ra$ well below the values where steady rotating columnar convection occurs, the bulk flow becomes turbulent. Our results imply that rotating convective flows in liquid metals do not develop in the form of quasisteady columns, as in moderate-$Pr$ fluids, but in the form of oscillatory convective motions. Thus, thermally driven flows in low-$Pr$ geophysical and astrophysical fluids can differ substantively from those occurring in $Pr\simeq 1$ models. Furthermore, our experimental results show that relatively low-frequency wall modes are an essential dynamical component of rapidly rotating convection in liquid metals
