Die explorative hochschuldidaktische Studie geht der Frage nach, ob die Erfahrungen im Praxissemester und in den erziehungswissenschaftlichen Begleitseminaren dazu beitragen, die subjektive Sicht der Studierenden auf das erziehungswissenschaftliche Studium und den Nutzen einer erziehungswissenschaftlichen Reflexion eigener pädagogischer Praxis zu verändern. Die zentrale These des Beitrages lautet: Erst die reflektierte fallanalytische erziehungswissenschaftliche Auseinandersetzung mit der eigenen pädagogischen Praxis führt zu einer höheren Bedeutungszuschreibung an das erziehungswissenschaftliche Studium und lässt die Erziehungswissenschaft aus Sicht der Studierenden nach dem Praxissemester zur wichtigen Berufswissenschaft werden. Grundlage der Studie sind schriftliche Statements Studierender (n = 184) aus einem seminaristischen Reflexions- und Diskussionsprozess am Ende des Praxissemesters aus einem Zeitraum von acht Jahren. Abgeschlossen wurde der Beitrag im August 2019.
“Broadcast your gender.”
(2022)
Social media platforms provide a large array of behavioral data relevant to social scientific research. However, key information such as sociodemographic characteristics of agents are often missing. This paper aims to compare four methods of classifying social attributes from text. Specifically, we are interested in estimating the gender of German social media creators. By using the example of a random sample of 200 YouTube channels, we compare several classification methods, namely (1) a survey among university staff, (2) a name dictionary method with the World Gender Name Dictionary as a reference list, (3) an algorithmic approach using the website gender-api.com, and (4) a Multinomial Naïve Bayes (MNB) machine learning technique. These different methods identify gender attributes based on YouTube channel names and descriptions in German but are adaptable to other languages. Our contribution will evaluate the share of identifiable channels, accuracy and meaningfulness of classification, as well as limits and benefits of each approach. We aim to address methodological challenges connected to classifying gender attributes for YouTube channels as well as related to reinforcing stereotypes and ethical implications.

The Sino-Japanese War of 1894/95 is usually only briefly mentioned in studies on diplomatic history. Especially the war's impact on Wilhelmine foreign and world policy (Weltpolitik) has been largely neglected. However, the events in East Asia had a profound influence on the political leadership in Berlin. The Wilhelmstrasse's attitude towards the conflict changed rapidly when the course of the war in Northeast Asia made a collapse of the Qing Empire increasingly likely. Afraid of the prospect of being left empty handed in an upcoming scramble for China, German diplomacy got active in early 1895. Driven by a hectic activism which soon should become a dominant feature of Weltpolitik, Berlin concluded an ad-hoc alliance with St. Petersburg and Paris. In April 1895, this unlikely coalition intervened against Tokyo. While the Triple Intervention served primarily Russia's interest to maintain the status quo on the Chinese mainland, Germany aimed at the acquisition of a military and commercial base in Northeast Asia. Driven by public opinion, the naval leadership and the Emperor Wilhelm II., the formerly neutral and reserved German diplomacy changed towards an aggressive and unstable imperialist policy, which ultimately resulted in the acquisition of Qingdao in November 1897.
Dieses Papier thematisiert die völkerstrafrechtliche Einordnung rein störender, also nicht zerstörender Cyberoperationen. Nach der erforderlichen Begriffsklärung werden die einzelnen Fragen der Anwendbarkeit des Völkerstrafrechts erörtert und geprüft, welche Tatbestände durch solche Aktionen verwirklicht werden können.
Gegenstand der anspruchsvollen Examensübungsklausur ist im ersten Teil ein aufsehenerregendes Urteil des OLG Hamm zu einer sog. cold-water-Challenge (NJOZ 2018, 1289). Eine große Herausforderung besteht zunächst in der Wahl eines übersichtlichen Aufbaus, der vollständig ist und zugleich Redundanzen vermeidet. Darüber hinaus eignet sich die Aufgabenstellung angesichts ihrer Stofffülle hervorragend zum Einüben der Schwerpunktsetzung. Im Detail bietet sich immer wieder die Möglichkeit, sich »nach oben abzusetzen«. Für eine gute Bewertung müssen nicht alle Einzelfragen diskutiert werden. Inhaltlich ist mit den Verkehrspflichten ein deliktsrechtlicher Klassiker zu bewerkstelligen, und eher unbekanntere Anspruchsgrundlagen aus dem Deliktsrecht wollen erkannt und subsumiert werden. Insoweit sind Auslegungs‑ und Argumentationsvermögen unter Beweis zu stellen. Sodann erfolgt ein Streifzug durch das Schadensrecht, wenn es um die Erstattung von Besuchskosten geht. Abschließend geht es im zweiten Teil um eine Entscheidung des BGH zu den umstrittenen Anforderungen an einen Kündigungsgrund nach dem Eintritt von Haushaltsangehörigen in den Mietvertrag infolge des Todes der Mieterpartei (BGHZ 217, 263 = NJW 2018, 2397), deren Kenntnis von Studierenden nicht erwartet werden kann. Die Grundzüge des Mietrechts müssen beherrscht und mit einem geschickten Argumentationsvermögen verbunden werden.
Background
Coronavirus disease (COVID-19) has a severe impact on all aspects of patient care. Among the numerous biomarkers of potential validity for diagnostic and clinical management of COVID-19 are biomarkers at the interface of iron metabolism and inflammation.
Methods
The follow-up study included 54 hospitalized patients with laboratory-confirmed COVID-19 with a moderate and severe/critical form of the disease. Iron deficiency specific biomarkers such as iron, ferritin, transferrin receptor, hepcidin, and zinc protoporphyrin (ZnPP) as well as relevant markers of inflammation were evaluated twice: in the first five days when the patient was admitted to the hospital and during five to 15 days; and their validity to diagnose iron deficiency was further assessed. The regression and Receiver Operating Characteristics (ROC) analyses were performed to evaluate the prognosis and determine the probability for predicting the severity of the disease in the first five days of COVID-19.
Results
Based on hemoglobin values, anemia was observed in 21 of 54 patients. Of all iron deficiency anemia-related markers, only ZnPP was significantly elevated (P<0.001) in the anemic group. When patients were grouped according to the severity of disease, slight differences in hemoglobin or other anemia-related parameters could be observed. However, the levels of ZnPP were significantly increased in the severely ill group of patients. The ratio of ZnPP to lymphocyte count (ZnPP/L) had a discrimination power stronger than the neutrophil to lymphocyte count ratio (N/L) to determine disease severity. Additionally, only two markers were independently associated with the severity of COVID-19 in logistic regression analysis; D-dimer (OR (5.606)(95% CI 1.019–30.867)) and ZnPP/L ratio (OR (74.313) (95% CI 1.081–5108.103)).
Conclusions
For the first time ZnPP in COVID-19 patients were reported in this study. Among all iron-related markers tested, ZnPP was the only one that was associated with anemia as based on hemoglobin. The increase in ZnPP might indicate that the underlying cause of anemia in COVID-19 patients is not only due to the inflammation but also of nutritional origin. Additionally, the ZnPP/L ratio might be a valid prognostic marker for the severity of COVID-19.
