Right-wing populism challenges the societies in Europe. The rise of such movements and parties are a threat to peace and democracy in Germany. This article focuses the possibilities as well as the boundaries of political education under the current circumstances. To this end, it discusses theoretical explanations based on approaches in peace education, political didactics and social sciences to deal with right-wing populism in practice. (DIPF/Orig.).
Durch die voranschreitende Digitalisierung bieten sich neue Ansätze für Designs und Methoden in der Jugendforschung. Mit vielfältigen digitalen Möglichkeiten wachsen auch Chancen für inklusiv angelegte Befragungen. Dieser Beitrag fokussiert exemplarisch gehörlose bzw. hörbeeinträchtigte gebärdensprachige Jugendliche und stellt nach einem theoretischen und empirischen Überblick die Frage, ob und inwieweit diese heterogene Gruppe Jugendlicher durch in digitale Fragebögen implementierte Videos in Gebärdensprache profitieren kann. Anhand zweier kontrastiver Fallvignetten sollen Erfahrungen aus dem Projekt „Inklusive Methoden“ in Bezug auf Möglichkeiten, Voraussetzungen, Herausforderungen und Grenzen digitaler Befragungen mit Gebärdensprachvideos dargestellt und diskutiert werden.
Clot formation within membrane oxygenators (MOs) remains a critical problem during extracorporeal membrane oxygenation (ECMO). The composition of the clots-in particular, the presence of von Willebrand factor (vWF)-may be an indicator for prevalent nonphysiological flow conditions, foreign body reactions, or coagulation abnormalities in critically ill patients. Mats of interwoven gas exchange fibers from randomly collected MOs (PLS, Maquet, Rastatt, Germany) of 21 patients were stained with antibodies (anti-vWF and anti-P-selectin) and counterstained with 4 ',6-diamidino-2-phenylindole. The extent of vWF-loading was correlated with patient and technical data. While 12 MOs showed low vWF-loadings, 9 MOs showed high vWF-loading with highest accumulations close to crossing points of adjacent gas fibers. The presence and the extent of vWF-fibers/"cobwebs," leukocytes, platelet-leukocyte aggregates (PLAs), and P-selectin-positive platelet aggregates were independent of the extent of vWF-loading. However, the highly loaded MOs were obtained from patients with a significantly elevated SOFA score, severe thrombocytopenia, and persistent liver dysfunction. The coagulation abnormalities of these critically ill patients may cause an accumulation of the highly thrombogenic and elongated high-molecular-weight vWF multimers in the plasma which will be trapped in the MOs during the ECMO therapy.
Independent component analysis (ICA), as a data driven method, has shown to be a powerful tool for functional magnetic resonance imaging (fMRI) data analysis. One drawback of this multivariate approach is, that it is naturally not convenient for analysis of group studies. Therefore various techniques have been proposed in order to overcome this limitation of ICA. In this paper a novel ICA based work-flow for extracting resting state networks from fMRI group studies is proposed. An empirical mode decomposition (EMD) is used to generate reference signals in a data driven manner, which can be incorporated into a constrained version of ICA (cICA), what helps to overcome the inherent ambiguities. The results of the proposed workflow are then compared to those obtained by a widely used group ICA approach. It is demonstrated that intrinsic modes, extracted by EMD, are suitable to serve as references for cICA to obtain typical resting state patterns, which are consistent over subjects. This novel processing pipeline makes it transparent for the user, how comparable activity patterns across subjects emerge, and also the trade-off between similarity across subjects and preserving individual features can be well adjusted and adapted for different requirements in the new work-flow.
Hintergrund
Inhalte von Public Health werden in Deutschland in gesundheitsbezogenen Studiengängen an Hochschulen und Universitäten gelehrt. Ziel dieser Studie war es, Daten zur Lehre und zur Kooperation von Lehrenden von Public Health in gesundheitsbezogenen Studiengängen in Deutschland zur Verfügung zu stellen.
Methode
Eine Querschnittsuntersuchung wurde online-basiert vom 01.06. bis 15.09.2015 an 93 Hochschulen/Universitäten in Deutschland mit 351 Studiengangsverantwortlichen aus gesundheitsbezogenen Studiengängen durchgeführt. Einbezogen wurden Public Health Studiengänge und gesundheitsbezogene Studiengänge, deren Hochschulen bzw. Universitäten entweder Mitglied in der "Deutschen Gesellschaft für Sozialmedizin und Prävention" (DGSMP) oder in der Gesellschaft "Hochschulen für Gesundheit" (HOGE) sind. Teilgenommen an dieser Studie haben N=104 Studiengangsverantwortliche (43% Männer, 57% Frauen). In Public Health Studiengängen wurden „Global Health" und "Umwelt und Gesundheit" als Studieninhalte häufiger als in gesundheitsbezogenen Studiengängen benannt; in gesundheitsbezogenen Studiengängen wurden häufiger "Ethik" und "Gesundheitspsychologie" als Lehrinhalte benannt. Finanzielle Unterstützungen durch die Hochschulen/ Universitäten sowie strukturierte Partnerschaften zwischen Hochschulen und/ oder Universitäten werden von Lehrenden an Hochschulen (36%) und an Universitäten (40%) gewünscht. Lehrende an Hochschulen wünschen darüber hinaus Promotionspartnerschaften.
Schlussfolgerung
Bisher gibt es in Deutschland keine einheitlichen fachlichen Qualitätskriterien für Absolvierende von Public Health bzw. gesundheitsbezogenen Studiengängen. Zudem gibt es nach Aussage der Studiengangsverantwortlichen dieser Studiengänge wenig Kooperation zwischen Lehrenden der Public Health bzw. der gesundheitsbezogenen Studiengänge.
In this thesis, a concept for the automated use of network planning processes, which is part of the decision support system developed in the framework of the EU project CrossEnergy, is presented. This publication focuses on the automatic processing of input data and subsequent network modeling as well as the coordination of network extension measures for the systematic solution of static voltage and current problems. Different variants are calculated in order to be able to compare the design technologies.
Masonry structures were built by means of various techniques, using materials whose properties exhibit a considerable scatter depending on the period of construction, region- specific soil resources and manufacturing procedures. Significant spatial variability within the structural system is often observed due to diverse deterioration mechanisms. Therefore, it is important to obtain case-specific information on the mechanical properties of existing masonry structures.
The case study of a historic building illustrates how the number of destructive tests (DTs) used to calibrate non-destructive tests (NDTs) can be optimised for the reliability assessment. Calibrated NDTs are used to establish the probabilistic model for compressive masonry strength. The specific focus is on compressive strength of masonry units; tests of mortar strength are only briefly discussed.
The preliminary assessment is based on non-calibrated NDTs. The number of DTs for calibration is then optimised by means of probabilistic cost optimisation, considering also possible subsequent actions – ‘do nothing’ or ‘strengthen the structure’. It appears that the estimates of masonry unit strength based on NDTs are associated with large dispersion and may be significantly biased. Consequently, it is often beneficial to conduct at least one DT. A practical tool is provided to determine optimum number of DTs for different outcomes of a NDT survey and different failure consequences.
For material testing, qualification and subsequent assessment fast, simple, reliable and economic methods are needed. This paper provides an overview of different techniques to determine the depth of carbonation in cementitious materials. The easiest and cheapest way is to remove a core or a fragment of concrete cover and spray a colour indicator on the fresh fractured surface (by splitting). Here, 1 % phenolphthalein in 70 % ethanol is most widely used. However, this only indicates in which area the concrete has a pH value below 8.2-10, but not the actual carbonation front which is on average about 20 % higher. Since phenolphthalein is carcinogenic, alternative colour indicators were investigated in the laboratory. 0.5 % Curcumin showed similar colour change to phenolphthalein. In addition, 0.1 % thymolphthalein proved to be an alternative. Scattering within one measurement was lower than for phenolphthalein and the results were closer to the carbonation depths determined by different analytical methods (TGA and LA-ICP-MS). Furthermore, the transition pH-value of thymolphthalein is in the area of 9.3-10.5 which is closer to the actual carbonation front, allowing a more accurate assessment of the risk of reinforcement corrosion.
Mobile cranes are regularly operated in regions which experience ultra deep operating temperatures of down to -60?C (-76?F). In safety regulated work environments crane operations will be suspended simply because the lowest wire rope working temperature stated in the applicable standards is -40?C/F. Examples of ultra deep temperature wire rope application are shown in Figure 1.1 and 1.3. It should be noted that this paper is written in conjunction with a paper written by the co-author Ulrich Briem titled “Fatigue Behaviour of Rope Wires”, presented and published in unison with this one. In order to analyze the behaviour under ultra deep temperature conditions, tests on wire rope as well as on rope wires were carried out. In the following, static tensile and bending test results with rope and rope wires will be reported, which were carried out in conditions of down to -95?C (-139?F) as well as at room temperature. The conclusion is that the results of these tests can be adopted to crane wire rope as well.
The rope curve line of a tensioned rope can be described by means of the catenary curve. Opposed to that, the curved line of a free bent rope cannot be described by an analytical function. Practical applications of free bending are for example at tail ropes at the bottom of shaft in rope drives with traction sheaves. The question whether the maximum diameter of rope loop is small enough for the diameter of the shaft is highly interesting. In [1] a method was presented to calculate the curved line of free bent ropes numerically by help of energy methods. An analytical description of rope curve line would be very helpful. Beginning with the structure of a rope curve line of tensioned rope (catenary curve) and considering the influence of bending stiffness, the structure of an analytical equation for the curve line of a free bent rope will be developed. The main focus of this paper is to develop and to describe the structure of such an analytical equation. To get a first idea about the values of the constants in that analytical equation a few test results were evaluated. But these equations consider the static rope behavior only. Due to dynamic effects in the rope while running through the loop at the bottom of a shaft, pendulousness of the tail rope occurs.
