COVID-19-Impfstrategien für Beschäftigte deutscher Kliniken: Ergebnisse einer Befragung von Leitungen der (Krankenhaus‑)Hygiene im Rahmen des B-FAST-Projektes
BACKGROUND AND AIM: At the beginning of the COVID-19 vaccination campaign in Germany, employees in medical facilities were prioritised for vaccination against SARS-CoV‑2 due to the high risk of exposure and contact with vulnerable groups. Hospitals were therefore encouraged to organise and implement the vaccination of their employees as soon as possible. The aim of the study was to record the practice regarding the vaccination strategy for employees in German hospitals. METHODS: In a self-developed cross-sectional study, infection control practitioners of all German university hospitals as well as non-university hospitals in Lower Saxony and Bavaria were surveyed in March 2021. The data were stratified according to the characteristics of university hospitals and non-university hospitals. RESULTS: Of 416 invitations sent out, 100 questionnaires (university hospitals: 33; non-university hospitals: 67) were completed. University hospitals reported greater vaccination capacity than non-university hospitals, but a limiting factor was uncertain vaccine supply. Vaccination information campaigns were planned or had already been conducted in 89% of clinics. About two-thirds of the respondents (70%) said they did not plan to conduct antibody tests on vaccinated employees. A follow-up of vaccinated employees to detect possible SARS-CoV‑2 infections by PCR was planned by 41% of the respondents. In case of detection of SARS-CoV‑2 infection, 72% of the respondents had planned further diagnostic procedures. DISCUSSION: All hospitals were able to achieve rapid implementation of COVID-19 vaccination of their employees. At the time of the survey, there was also much uncertainty regarding the management of breakthrough infections as well as the need for booster vaccinations
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Differential integrin activation in the restenosis and endothelialization process of human stents
Die αvβ3 und α5β1 Integrine spielen als transmembrane Rezeptoren eine entscheidende Rolle bei der Reendothelialisierung und Restenose nach einer Stentimplantation. Durch die Immobilisierung des αvβ3 Peptidomimetikums auf der Stentoberfläche wird die Adhäsion der CAECs gefördert. Wenn das α5β1 Peptidomimetikum freigesetzt wird, wird der Prozess der Proliferation und Zellmigration der CASMCs, welches der Grund für die Neointima ist, gehemmt. Im β1 Integrin-knockout Mausmodell wird die Neointima während der Gefäßheilung einer simulierten Verletzung vermindert.The transmembrane receptors αvβ3 and α5β1 Integrin play a significant role in reendothelialization and restenosis after stent implantation. By the immobilization of αvβ3 peptide mimetic on the surface of the stent, adhesion of CAECs is facilitated. If α5β1 peptide mimetic is released, the process of proliferation and migration of CASMCs, the reason for neointimal, is inhibited. With a β1 Integrin-knockout mouse model, the neointimal growth is attenuated during the vascular healing after a simulated injury
