Eignen sich Kindernachrichten für Kinder?: Eine vergleichende Qualitätsanalyse der Kindernachrichtensendungen Logo! und Newsround

Nachrichtensendungen für Kinder sind im Rahmen der politischen Sozialisation bedeutsam und sehen sich mit verschiedenen Anforderungen konfrontiert. In der vorliegenden Studie unterziehen die Autorinnen die deutsche Kindernachrichtensendung Logo! und die britische Kindernachrichtensendung Newsround einem inhaltsanalytischen Qualitätsvergleich. Dazu leiten sie Qualitätskriterien aus normativen, inhaltlichen sowie formalen Beurteilungskriterien aus Rezipienten-, Produzenten- sowie aus wissenschaftlicher Sicht ab, die sie für Aussagen über die Aufbereitung und Eignung dieser Kindernachrichtenprogramme heranziehen. Die Ergebnisse dieser tiefgründigen Analyse bieten detaillierten Aufschluss über Gemeinsamkeiten und Unterschiede der untersuchten Sendungen und ermöglichen so eine differenzierte Betrachtung der Frage danach, was die Qualität von Kindernachrichtensendungen – auch unter interkulturellen Gesichtspunkten – ausmacht.TV News programs for children, within the context of political socialization, are not only hugely important but are also being faced with constant challenges. The following study focuses on Germany’s Logo! and Britain’s Newsround, two of the larger scale television news programs on offer for children. The study offers ananalytical, quality comparison of the two shows. It looks both at the quality criteria of normative, context-related and formal assessment criteria, whilst exploring the perspective of the recipient, the producer and more scientific approaches. The study concludes with an analysis of the format preparation of the two shows and analyses their respective suitability for children. The study offers a profound insight into the similarities and differences between these two broadcasts and considers how we can attempt to measure the quality of children’s news programs

Transparent, flexible, and strong 2,3-dialdehyde cellulose films with high oxygen barrier properties

2,3-Dialdehyde cellulose (DAC) of a high degree of oxidation (92% relative to AGU units) prepared by oxidation of microcrystalline cellulose with sodium periodate (48 degrees C, 19 h) is soluble in hot water. Solution casting, slow air drying, hot pressing, and reinforcement by cellulose nanocrystals afforded films (similar to 100 mu m thickness) that feature intriguing properties: they have very smooth surfaces (SEM), are highly flexible, and have good light transmittance for both the visible and near-infrared range (89-91%), high tensile strength (81-122 MPa), and modulus of elasticity (3.4-4.0 GPa) depending on hydration state and respective water content. The extraordinarily low oxygen permeation ofPeer reviewe

Immunoadsorption for Treatment of Patients with Suspected Alzheimer Dementia and Agonistic Autoantibodies against Alpha1a-Adrenoceptor—Rationale and Design of the IMAD Pilot Study

Background: agonistic autoantibodies (agAABs) against G protein-coupled receptors (GPCR) have been linked to cardiovascular disease. In dementia patients, GPCR-agAABs against the α1- and ß2-adrenoceptors (α1AR- and ß2AR) were found at a prevalence of 50%. Elimination of agAABs by immunoadsorption (IA) was successfully applied in cardiovascular disease. The IMAD trial (Efficacy of immunoadsorption for treatment of persons with Alzheimer dementia and agonistic autoantibodies against alpha1A-adrenoceptor) investigates whether the removal of α1AR-AABs by a 5-day IA procedure has a positive effect (improvement or non-deterioration) on changes of hemodynamic, cognitive, vascular and metabolic parameters in patients with suspected Alzheimer’s clinical syndrome within a one-year follow-up period. Methods: the IMAD trial is designed as an exploratory monocentric interventional trial corresponding to a proof-of-concept phase-IIa study. If cognition capacity of eligible patients scores 19–26 in the Mini Mental State Examination (MMSE), patients are tested for the presence of agAABs by an enzyme-linked immunosorbent assay (ELISA)-based method, followed by a bioassay-based confirmation test, further screening and treatment with IA and intravenous immunoglobulin G (IgG) replacement. We aim to include 15 patients with IA/IgG and to complete follow-up data from at least 12 patients. The primary outcome parameter of the study is uncorrected mean cerebral perfusion measured in mL/min/100 gr of brain tissue determined by magnetic resonance imaging with arterial spin labeling after 12 months. Conclusion: IMAD is an important pilot study that will analyze whether the removal of α1AR-agAABs by immunoadsorption in α1AR-agAAB-positive patients with suspected Alzheimer’s clinical syndrome may slow the progression of dementia and/or may improve vascular functional parameters

Psychological placebo and nocebo effects on pain rely on expectation and previous experience

AbstractExpectation and previous experience are both well established key mediators of placebo and nocebo effects. However, the investigation of their respective contribution to placebo and nocebo responses is rather difficult because most placebo and nocebo manipulations are contaminated by pre-existing treatment expectancies resulting from a learning history of previous medical interventions. To circumvent any resemblance to classical treatments, a purely psychological placebo-nocebo manipulation was established, namely, the “visual stripe pattern–induced modulation of pain.” To this end, experience and expectation regarding the effects of different visual cues (stripe patterns) on pain were varied across 3 different groups, with either only placebo instruction (expectation), placebo conditioning (experience), or both (expectation + experience) applied. Only the combined manipulation (expectation + experience) revealed significant behavioral and physiological placebo–nocebo effects on pain. Two subsequent experiments, which, in addition to placebo and nocebo cues, included a neutral control condition further showed that especially nocebo responses were more easily induced by this psychological placebo and nocebo manipulation. The results emphasize the great effect of psychological processes on placebo and nocebo effects. Particularly, nocebo effects should be addressed more thoroughly and carefully considered in clinical practice to prevent the accidental induction of side effects.PerspectiveEven purely psychological interventions that lack any resemblance to classical pain treatments might alter subjective and physiological pain correlates. A manipulation of treatment expectation and actual treatment experience were mandatory to elicit this effect. Nocebo effects were especially induced, which indicated the necessity for prevention of accidental side effects besides exploitation of placebo responses

Zentrale Befunde zu aktuellen Arbeitsmarktthemen

Die Zahlen zur Beschäftigung und zum Leistungsbezug rechtfertigen es gegenwärtig nicht, die Zuwanderung aus Bulgarien und Rumänien pauschal als 'Armutszuwanderung' zu qualifizieren. Zur Jahresmitte 2013 waren rund 60 Prozent der Bulgaren und Rumänen im erwerbsfähigen Alter in Deutschland erwerbstätig. Die Arbeitslosenquote lag bei 7,4 Prozent und der Anteil der SGB-II-Leistungsempfänger an der bulgarischen und rumänischen Bevölkerung bei 10 Prozent. Allerdings haben 46 Prozent der Bulgaren und Rumänen, die nach 2007 zugewandert sind, keine abgeschlossene Berufsausbildung. In einigen strukturschwachen Kommunen wie Duisburg, Dortmund und Berlin konzentrieren sich die sozialen und ökonomischen Probleme der Bulgaren und Rumänen. Hier sind nicht nur die Arbeitslosen- und Leistungsempfängerquoten zum Teil sehr hoch. Vor allem sind hier 60 bis 75 Prozent der Bulgaren und Rumänen weder erwerbstätig noch im Leistungsbezug. Durch Einführung der vollständigen Arbeitnehmerfreizügigkeit steigen einerseits die Beschäftigungsmöglichkeiten im ersten Arbeitsmarkt, andererseits erweitert sich der Kreis der potenziellen Leistungsbezieher. Unter optimistischen Annahmen wird die Zahl der SGB-II-Leistungsempfänger zum Jahresende 2014 auf 50.000 bis 58.000, unter extrem pessimistischen Annahmen auf 80.000 bis 93.000 Personen steigen. Die Arbeitsmarktpolitik sollte sich vor allem auf die Vermittlung von geringer Qualifizierten fokussieren. Strukturschwache Kommunen, in denen sich die Probleme konzentrieren, könnten mit Mitteln aus dem Bundeshaushalt kompensiert werden. Der Leistungsausschluss von EU-Bürgern, die sich zum Zweck der Arbeitssuche in Deutschland aufhalten, ist ökonomisch sinnvoll und sollte beibehalten werden

Complex morphology and functional dynamics of vital murine intestinal mucosa revealed by autofluorescence 2-photon microscopy

The mucosa of the gastrointestinal tract is a dynamic tissue composed of numerous cell types with complex cellular functions. Study of the vital intestinal mucosa has been hampered by lack of suitable model systems. We here present a novel animal model that enables highly resolved three-dimensional imaging of the vital murine intestine in anaesthetized mice. Using intravital autofluorescence 2-photon (A2P) microscopy we studied the choreographed interactions of enterocytes, goblet cells, enteroendocrine cells and brush cells with other cellular constituents of the small intestinal mucosa over several hours at a subcellular resolution and in three dimensions. Vigorously moving lymphoid cells and their interaction with constituent parts of the lamina propria were examined and quantitatively analyzed. Nuclear and lectin staining permitted simultaneous characterization of autofluorescence and admitted dyes and yielded additional spectral information that is crucial to the interpretation of the complex intestinal mucosa. This novel intravital approach provides detailed insights into the physiology of the small intestine and especially opens a new window for investigating cellular dynamics under nearly physiological conditions

Identification and Characterisation of Pseudomonas 16S Ribosomal DNA from Ileal Biopsies of Children with Crohn's Disease

Molecular analysis of bacterial 16S rRNA genes has made a significant contribution to the identification and characterisation of bacterial flora in the human gut. In particular, this methodology has helped characterise bacterial families implicated in the aetiology of inflammatory bowel disease (IBD). In this study we have used a genus specific bacterial 16S PCR to investigate the prevalence and diversity of Pseudomonas species derived from the ileum of children with Crohn's disease (CD), and from control children with non-inflammatory bowel disease (non-IBD) undergoing their initial endoscopic examination. Fifty eight percent of CD patients (18/32) were positive using the Pseudomonas PCR, while significantly fewer children in the non-IBD group, 33% (12/36), were PCR positive for Pseudomonas (p<0.05, Fischer's exact test). Pseudomonas specific 16S PCR products from 13 CD and 12 non-IBD children were cloned and sequenced. Five hundred and eighty one sequences were generated and used for the comparative analysis of Pseudomonas diversity between CD and non-IBD patients. Pseudomonas species were less diverse in CD patients compared with non-IBD patients. In particular P.aeruginosa was only identified in non-IBD patients
