Power and Limits of a Picture: On the Notion of Thought Experiments in the Philosophy of Literature
No full textEgbert von Lepel and the Invention of the Spark-Gap Transmitter
No full textOn 29 October 1923, radio broadcasting or “Rundfunk” was officially opened in the Voxhaus in Berlin and thus the new communication medium was now also available in Germany, but later than in other countries such as the US and the UK. However, first experiments with wireless telephony, which is the technical basis of this medium, were carried out more than ten years earlier (Pungs, 1922; Mathis, 2019; Titze and Mathis, 2020; Mathis and Titze, 2021). One of the pioneers of this technology was the German Egbert von Lepel, who developed in 1907 a new concept of wireless transmitters that was also suitable for use in wireless telephony. The concept later became known as the quenched spark-gap transmitter (“Löschfunkensender”) or ”Singing Spark” transmitter where a specific variant was developed by the Gesellschaft für Drahtlose Telegraphie (GDT: “Wireless Telegraph Society”), System Telefunken. This article discusses the history of this type of transmitter using new historical sources from national and international archives. It turns out that contrary to what is known on this subject from almost all publications on the history of early wireless technology, the German Imperial Patent Office decided in January 1911 that Lepel's patent was granted as the most fundamental for quenched spark-gap transmitters. With the disclosure of this important historical source, the question of the origin of the invention of the quenched spark-gap transmitter must be reassessed
Identification of problems in functioning of people with sleep disorders in a clinical setting using the International Classification of Functioning Disability and Health (ICF) Checklist
No full textWe conducted an explorative, cross-sectional, multi-centre study in order to identify the most common problems of people with any kind of (primary) sleep disorder in a clinical setting using the International Classification of Functioning, Disability and Health (ICF) as a frame of reference. Data were collected from patients using a structured face-to-face interview of 45-60?min duration. A case record form for health professionals containing the extended ICF Checklist, sociodemographic variables and disease-specific variables was used. The study centres collected data of 99 individuals with sleep disorders. The identified categories include 48 (32%) for body functions, 13 (9%) body structures, 55 (37%) activities and participation and 32 (22%) for environmental factors. 'Sleep functions' (100%) and 'energy and drive functions', respectively, (85%) were the most severely impaired second-level categories of body functions followed by 'attention functions' (78%) and 'temperament and personality functions' (77%). With regard to the component activities and participation, patients felt most restricted in the categories of 'watching' (e.g. TV) (82%), 'recreation and leisure' (75%) and 'carrying out daily routine' (74%). Within the component environmental factors the categories 'support of immediate family', 'health services, systems and policies' and 'products or substances for personal consumption [medication]' were the most important facilitators; 'time-related changes', 'light' and 'climate' were the most important barriers. The study identified a large variety of functional problems reflecting the complexity of sleep disorders. The ICF has the potential to provide a comprehensive framework for the description of functional health in individuals with sleep disorders in a clinical setting
Physics Nobel laureate Wolfgang Ketterle : a scientometric portrait
No full textWolfgang Ketterle was honoured with the Nobel Prize in Physics (2001) at 44 years of biological age and at 20 years of research publishing career. He had 115 publications during 1982 – 2002 in domains: Bose-Einstein Condensation (68), Laser Spectroscopy (30), and Atomic Physics (17) which were analysed for authorship pattern with his 68 collaborators. Most active researchers having number of publications with Wolfgang Ketterle were : S. Inouye (26), A. P. Chikkatur (20), M. R. Andrews (19), D. M. Stampur-Kurn (18), D. S. Durfee (17), H. J. Miesner (17), D. E. Pritchard (17), H. Walther (12), M. O. Mewes (12), D. M. Kurn (12), C. Raman (12), J. Stenger (12), J. Wolfrum (11), A. Arnold (10), N. J. van Druten (10), A. Gorlitz (10), and S. Gupta (10). His productivity coefficient was 0.78 which clearly indicates that his productivity increased after 50 percentile age. Highest collaboration coefficient (1) for Wolfgang Ketterle was found in 1983-1985, 1988, 1991-1995, and 2001. The publication concentration was 5.21% and publication density was 2.01. The core journals publishing his papers were: Phys. Rev. Lett. (30), Applied Physics-B (7), Journal of Chemical Physics (5), Nature (5), Physics Review-A (5), and Science (5). Most prolific keywords in titles were: Bose-Einstein condensate (38), Bose-Einstein condensation (15), Observation (9), Helium hydride (8), Emission spectrum, (6) Suppression (4). The ‘biobibliometrics’ term is used for a method of retrieving and visualizing biological information that uses co-occurrence of gene naming terms in Medical Sciences to generate semantic links between genes. Therefore it is suggested that ‘Scientometric Portrait’ is the appropriate phrase for the studies on scientists and ‘Informetric Portrait’ for the studies pertaining to researchers in other disciplines such as arts, humanities, and social sciences

“Poland represented existential experiences of resistance, political experiences and intellectual impact”. Marek Zybura in conversation with Wolfgang Templin, the author of the German biography of Józef Piłsudski
No full textWolfgang Templin (born in 1948) was active in the democratic resistance in the former GDR. He co‑founded the party Bündnis 90 in reunified Germany and was writer and author of history books. In the conversation with Marek Zybura (born in 1957) —the Chair of History of Literature and Culture of Germany in the Willy Brandt Centre of German and European Studies at the University of Wroclaw—Templin discusses the origins of his Piłsudski biography (2022), which is being published in the Polish translation by Bellona in Warsaw
