Academic search systems aid users in finding information covering specific topics of scientific interest and have evolved from early catalog-based library systems to modern web-scale systems. However, evaluating the performance of the underlying retrieval approaches remains a challenge. An increasing amount of requirements for producing accurate retrieval results have to be considered, e.g., close integration of the system’s users. Due to these requirements, small to mid-size academic search systems cannot evaluate their retrieval system in-house. Evaluation infrastructures for shared tasks alleviate this situation. They allow researchers to experiment with retrieval approaches in specific search and recommendation scenarios without building their own infrastructure. In this paper, we elaborate on the benefits and shortcomings of four state-of-the-art evaluation infrastructures on search and recommendation tasks concerning the following requirements: support for online and offline evaluations, domain specificity of shared tasks, and reproducibility of experiments and results. In addition, we introduce an evaluation infrastructure concept design aiming at reducing the shortcomings in shared tasks for search and recommender systems.

In recent years there have been numerous technical innovations such as CGM systems or insulin pumps that have made life easier for people with type 1 diabetes. However, this also means that more and more information is available. The aim of the present study is to find out more about the daily handling of information. The following research question was asked: What information do people with type 1 diabetes use? To answer this research question, a quantitative online survey of people with type 1 diabetes was conducted by Prof. Dr. Matthias Fank at the Technical University of Cologne. The online survey mainly consisted of 25 closed questions, which were asked on a scale from 0 to 10. The responses of 1,025 people who are at least 18 years old were included in the evaluation. The most important information for type 1 diabetics is the "current value". 67.5% have this on Place 1 placed. Current glucose levels are provided by CGM systems used by 94.2% of people with type 1 diabetes. Quarterly visits to the diabetologist are important and provide important information. 30.8% “completely” agree with this statement on a scale from 0 to 10. Only 2.2% of people with type 1 diabetes are satisfied with their current diabetes management apps. There is a desire for a manufacturer-independent app. The strongest agreement with a value of 10 was chosen by almost a quarter (24.6%) of the people with type 1 diabetes. The study provides an insight into diabetes therapy and shows the need for action.
This is the fifth time that TH Köln has conducted this study to examine the local XR industry´on behalf of Mediencluster NRW GmbH, a subsidiary of Film- und Medienstiftung NRW. Aside from the two surveys on the North Rhine-Westphalian sector, there have now been three studies on the nationwide XR (extended or cross reality) sector in Germany. By this we mean all companies that create products and services in the field of virtual, mixed or augmented reality (but not firms that employ XR as users).
In den letzten Jahren gab es zahlreiche technische Innovationen wie CGM Systeme oder Insulin- pumpen, die das Leben von Menschen mit Typ-1-Diabetes erleichtert haben. Dies führt aber auch dazu, dass immer mehr Informationen zur Verfügung stehen. Das Ziel der vorliegenden Studie ist es, mehr über den täglichen Umgang mit Informationen zu erfahren. Dazu wurde die folgende Forschungsfrage gestellt: Welche Informationen nutzen Menschen mit Typ-1-Diabetes?
Um diese Forschungsfrage zu beantworten, wurde eine quantitative Online-Befragung von Men- schen mit Typ-1-Diabetes von Prof. Dr. Matthias Fank an der Technischen Hochschule Köln durch- geführt. Die Online-Befragung bestand überwiegend aus 25 geschlossenen Fragen, die auf einer Skala von 0 bis 10 gestellt wurden. In die Auswertung gingen die Antworten von 1.025 Personen, die mindestens 18 Jahre alt sind, ein.
Die wichtigste Information für Typ-1-Diabetiker ist der “aktuelle Wert“. Diesen haben 67,5% auf
Platz 1 gesetzt. Der aktuelle Glukosewert wird durch CGM-Systeme bereitgestellt, die von 94,2% der Menschen mit Typ-1-Diabetes genutzt werden. Quartalsbesuche beim Diabetologen sind wichtig und liefern wichtige Informationen. Dieser Aussage stimmen 30,8% auf einer Skala von 0 bis 10 „voll und ganz“ zu.
Nur 2,2% der Menschen mit Typ-1-Diabetes sind mit ihren derzeitigen Apps für die Diabetestherapie zufrieden. Der Wunsch nach einer herstellerunabhängigen App ist vorhanden. Die stärkste Zustim- mung mit einem Wert von 10 haben fast ein Viertel (24,6%) der Menschen mit Typ-1-Diabetes ge- wählt. Die Studie gibt einen Einblick in die Diabetestherapie und zeigt Handlungsbedarf auf.
Fake News sind ein erhebliches, gesellschaftliches Problem. Öffentliche Bibliotheken können spezifische Schulungen und Selbstlernmaterial zum Thema Fake News bereitstellen, um die Informationskompetenz im Bereich Fake News von Kund_innen zu fördern und so dem Problem entgegenzuwirken. In der vorliegenden Studie wird untersucht, inwiefern nordrhein-westfälische Großstadtbibliotheken Schulungen und Selbstlernmaterial zum Thema Fake News durchführen bzw. bereitstellen. Außerdem wird ihr Bedarf an Video-Tutorials zum Thema Fake News ermittelt. Dazu werden eine Befragung von Mitarbeitenden aus 20 Großstadtbibliotheken und zusätzlich eine Sichtung der Internetseiten aller 31 Großstadtbibliotheken durchgeführt. Nur 3 Bibliotheken führen Informationen zum Thema Fake News auf ihren Internetseiten auf. Schulungen und Selbstlernmaterial zum Thema werden von jeweils 4 Bibliotheken angeboten. Der Bedarf in öffentlichen Bibliotheken an Video-Tutorials zum Thema ist sehr hoch. Es werden kurze, aufeinander aufbauende, leicht verständliche Video-Tutorials gewünscht, die mehrere Lehrziele fördern. Weitere Befunde stehen im Ergebnisteil. Als Implikation wird die Erstellung eines Video-Tutorials auf Grundlage der Befunde mit anschließender Bereitstellung zur Nachnutzung für öffentliche Bibliotheken empfohlen.
Mental illnesses in adolescence and young adulthood are steadily increasing. Thus,mental disorders represent an individual and societal challenge and an enormous health economicburden, creating an urgent need for research and action. Mental health problems are omnipresent inthe life of young people and the internet is the first resource, which helps them to understand theirsituation. Young people with migration background often have more difficulties accessing health careservices. Digital technologies offer an ideal opportunity for a low-threshold platform that addressesthe needs of young people. The current project “GeKo:mental” aims to design a multilingual websitefor Cologne-based adolescents and young adults that will enable them to obtain comprehensiveinformation about mental illness and health, treatment options and first contact points. To designthis website, this study aims to find out what kind of health information is needed and how itshould best be presented. Nine focus group discussions with adolescents and young adults withand without migration background (N = 68) were conducted; the focus group discussions took placeat schools, in an association for social youth work and in an cultural association, which is linkedto a mosque in Cologne, Germany. A qualitative content analysis was conducted on the gatheredmaterial. The participants reported concrete challenges and needs. The results will form the basis forthe development and design of a website.
Campylobacter spp. are one of the most important food-borne pathogens, which are quite susceptible to environmental or technological stressors compared to other zoonotic bacteria. This might be due to the lack of many stress response mechanisms described in other bacteria. Nevertheless, Campylobacter is able to survive in the environment and food products. Although some aspects of the heat stress response in Campylobacter jejuni are already known, information about the stress response in other Campylobacter species are still scarce. In this study, the stress response of Campylobacter coli and Campylobacter lari to elevated temperatures (46°C) was investigated by survival assays and whole transcriptome analysis. None of the strains survived at 46°C for more than 8 h and approximately 20% of the genes of C. coli RM2228 and C. lari RM2100 were differentially expressed. The transcriptomic profiles showed enhanced gene expression of several chaperones like dnaK, groES, groEL, and clpB in both strains, indicating a general involvement in the heat stress response within the Campylobacter species. However, the pronounced differences in the expression pattern between C. coli and C. lari suggest that stress response mechanisms described for one Campylobacter species might be not necessarily transferable to other Campylobacter species.
