Research into new forms of care for complex chronic diseases requires substantial efforts in the collection, storage, and analysis of medical data. Additionally, providing practical support for those who coordinate the actual care management process within a diversified network of regional service providers is also necessary. For instance, for stroke units, rehabilitation partners, ambulatory actors, as well as health insurance funds. In this paper, we propose the concept of comprehensive and practical receiver-oriented encryption (ROE) as a guiding principle for such data-intensive, research-oriented case management systems, and
illustrate our concept with the example of the IT infrastructure of the project STROKE OWL.
Concreteness of words has been studied extensively in psycholinguistic literature. A number of datasets have been created with average values for perceived concreteness of words. We show that we can train a regression model on these data, using word embeddings and morphological features, that can predict these concreteness values with high accuracy. We evaluate the model on 7 publicly available datasets. Only for a few small subsets of these datasets prediction of concreteness values are found in the literature. Our results clearly outperform the reported results for these datasets.
The growing importance of social media in the political arena seems to be in line with the mediatization of politics thesis, which states that mediated communication is becoming more important in politics and increasingly influences political processes. However, how politicians’ social media activities and politicians’ perceptions concerning social media have developed over time has rarely been examined. Moreover, it is unclear how the politicians’ activities and perceptions are related to each other. Referring to theoretical approaches, such as the influence of presumed influence approach, four surveys were conducted among German parliamentarians (MPs) between 2012 and 2016 (n = 194/149/170/118). The results indicate that the MPs’ self-reported social media activities and perceptions have remained remarkably constant since 2012. Regression analyses indicate that MPs’ self-reported social media activities and perceptions are hardly related to each other. This raises the question whether mediatization processes are indeed driven by politicians’ perceptions about media influences.
Background: Oral cancers (OC) are malignant lesions occurring in the oral cavity that include squamous cell carcinomas (SCC), salivary gland and odontogenic neoplasms. Even though it is the eighth most common malignancy globally but in Pakistan it is the second commonest type of cancer. Lack of awareness about ill-effects of preventable risk factors of oral cancer increases the burden of disease due to the associated high cost of treatment, permanent impairment and high mortality. Hence, awareness can be very helpful in prevention, control and early diagnosis of oral cancer.
Methods: A cross-sectional study was carried out among university students from Karachi, Pakistan during April to May 2018. Three hundred students were approached to participate in the study of which 277 agreed to participate. Pretested questionnaire was distributed and collected data was analysed using IBM SPSS version 23.
Results: There were 125 (45%) males and 152 (55%) females in the study and response rate was 94%. Sixty one percent (154/250) respondents correctly identified smoking, and tobacco chewing as possible causes of oral cancer. Almost one third (74%; 184/250) respondents correctly responded that oral cancer does not spread from person to person through touch or speaking. Sixty six percent (164/250) respondents believed that oral cancer is curable. Mean score of knowledge was higher in females (61%) than males (53%). Significantly higher number of females compared to male participants answered correctly to questions regarding cause of oral cancer, spread of disease and occurrence of oral cancer in AIDS patients.
Conclusions: Participants showed poor knowledge about oral cancer. Female participants showed better knowledge compared to male counterparts. Details about oral cancer should be incorporated in the university curriculum and periodic awareness programs should be organized for students.
Eine durch die Digitalisierung veränderte und auf Open Science ausgerichtete Wissenschaftspraxis benötigt angepasste Infrastrukturen und Services. Daraus ergeben sich verschiedene neue oder veränderte Aktionsfelder für wissenschaftliche Bibliotheken und Infrastruktureinrichtungen. Zu nennen sind zum Beispiel die nicht-textuellen Materialien wie Forschungsdaten, AV-Medien oder Software und die Umsetzung der FAIR-Prinzipien. Hinzu kommen neue Aufgaben im Bereich der Forschungsinformationen, zum Beispiel in der Unterstützung institutioneller Forschungsinformationssysteme, die Gestaltung von Open Access, die Unterstützung kollaborativen wissenschaftlichen Arbeitens sowie die Schaffung von offenen Infrastrukturen. In diesem Artikel werden diese Felder kurz vorgestellt und sich daraus abzeichnende Anforderungen an das bibliothekarische Berufsbild skizziert.
Das wissenschaftliche Publikationswesen befindet sich in einem Transformationsprozess, weg von der Bezahlung des lesenden Zugriffs durch den Kauf von Lizenzen durch Bibliotheken, hin zu der Vergütung der Verlagsleistungen durch Publikationsgebühren. Ziel ist der freie Zugang zu Forschungsergebnissen in wissenschaftlichen Publikationen und den dazugehörigen Forschungsdaten. Dieser freie Zugang zu wissenschaftlicher Literatur wird weltweit, unter dem Begriff Open Access gefördert und vorangebracht. Veränderungen in der Wissenschaft bedeuten auch immer Änderungen in den Arbeitsabläufen und im Aufgabenbereich wissenschaftlicher Bibliotheken. Diese Arbeit beschäftigt sich mit der Fragestellung, welche Angebote medizinische Fachbibliotheken in Deutschland, Österreich und der Schweiz den Wissenschaftlern ihrer Institution im Bereich des Open Access Publizierens bieten. Aufbauend auf den Ergebnissen einer Webseitenanalyse, werden Handlungsempfehlungen für die Ärztliche Zentralbibliothek im Universitätsklinikum Hamburg-Eppendorf für den Aufbau von Publikationsdiensten, insbesondere für Open Access, erstellt.
Hadoop is a Java-based open source programming framework, which supports the processing and storage of large volumes of data sets in a distributed computing environment. On the other hand, an overwhelming majority of organizations are moving their big data processing and storing to the cloud to take advantage of cost reduction – the cloud eliminates the need for investing heavily in infrastructures, which may or may not be used by organizations. This paper shows how organizations can alleviate some of the obstacles faced when trying to make Hadoop run in the cloud.
This feasibility study investigates the flexural properties of biocomposites containing woven flax textiles (plain, twill, satin) and woven twill patterned hybrid textiles containing flax-/glass or flax-/carbon mixture for lightweight applications. Synthetic fibers are integrated as weft and flax fibers are integrated as warp yarns using a double-rapier weaving machine with a Jacquard attachment. The corresponding biocomposites are manufactured via vacuum infusion process using a biobased epoxy resin as a matrix. The manufactured biocomposites are analyzed with regard to their density and flexural properties. The results show that the use of hybrid textiles offers a promising solution for the manufacture of biocomposites with a higher biobased content and significantly improved flexural properties. Furthermore, the introduction of high-performance synthetic fibers in textiles enables the manufacture of biocomposites with an isotropic mechanical performance.
Die Digitalisierung der Geisteswissenschaften eröffnet Wissenschaftlerinnen und Wissenschaftlern unter anderem neue Möglichkeiten des kollaborativen Arbeitens, des offenen Publizierens oder der direkten und öffentlichkeitswirksamen Wissenskommunikation. Auch die Literaturrecherche als ein Grundpfeiler wissenschaftlichen Arbeitens erfährt schon seit Jahren einen stetigen Wandel. Bibliotheken befinden sich als Anbieter von Literatur, Medien und Rechercheinstrumenten in einem Spannungsfeld: Die Kerntätigkeitsbereiche der Erwerbung sowie der Vermittlung von Informationskompetenz unterliegen auch aufgrund der zunehmenden Digitalisierung veränderten Rahmenbedingungen, die meistens außerhalb der Reichweite der lokalen Bibliothek liegen. Diese Bedingungen beeinflussen sowohl die Tätigkeiten des Bibliothekspersonals als auch die Informationsversorgung der Bibliothekskundinnen und -kunden stark.
In diesem Artikel soll mit Bezug auf eine Universitätsbibliothek mittlerer Größe und mit Blick auf eine ihrer wichtigsten Zielgruppen, nämlich die der Studierenden, dargestellt werden, wie sich im Zuge der zunehmenden Digitalisierung Fragen der Erwerbungspolitik und unterschiedliche Wege der Literaturrecherche auf das wissenschaftliche Arbeiten auswirken. Ein besonderes
Augenmerk gilt dabei dem Bestandsaufbau im Fachreferat Germanistik im Gefüge der an der Universität zu versorgenden Fächer. An der Schnittstelle zu Forschung, Lehre und Studium sind es die Fachreferentinnen und Fachreferenten der Bibliothek, die sowohl die Rahmenbedingungen als auch die verschiedenen Möglichkeiten der Literaturrecherche proaktiv vermitteln müssen.
Background: Antimicrobial resistance has become a serious global problem. A potential post-antibiotic era is threatening present and future medical advances. In Pakistan, the usage of antibiotic is unnecessarily high and due to over exposure to these drugs, bacteria are developing resistance against these drugs. It is necessary to improve public awareness about the rational use of antibiotics in order to bring a change in consumer’s behaviour. Therefore, present study was undertaken to assess the existing knowledge, attitude and practices related to antibiotic usage among university students.
Methods: A cross-sectional study was carried out among university students from Karachi, Pakistan during May-June 2018. 200 students were approached to participate in the study of which 159 agreed to participate (males: 70, females: 89). Pretested questionnaire was distributed to the study subjects and the collected data was analyzed using IBM SPSS version 23.
Results: Substantial number of (33% and 50%) participants were unaware about the differences in antibiotic: anti-inflammatory drugs and antibiotic: antipyretics respectively. 29% of the participants thought it is right to stop antibiotics only based on symptomatic improvement. Thirty nine percent and eighty three percent participants believed that antibiotics should always be prescribed to treat flu like symptoms and pneumonia respectively.
Conclusions: Participants demonstrated average knowledge about antibiotics. Similarly, their attitude and practice toward antibiotic use was associated with misconceptions. An educational intervention is necessary to make them aware about rational use of antibiotics.
Background:
In order to prevent child abuse, instruments measuring child abuse potential (CAP) need to be appropriate, reliable and valid.
Objective:
This study aimed to confirm the 6-factor structure of the Brief Child Abuse Potential Inventory (BCAPI) in a German sample of mothers and fathers, and to examine longitudinal predictors of CAP.
Participants and setting:
Two waves of data were collected from 197 mothers and 191 fathers of children aged 10–21 months for the “Kinder in Deutschland–KiD 0–3” in-depth study. Families were stratified based on prior self-report data for screening purposes.
Methods:
138 fathers and 147 mothers were included in the analysis (invalid: 25% mothers, 30% fathers). First, validity of reporting was examined. Second, confirmatory factor analysis (CFA) was employed to assess factor structure. Third, internal reliability and criterion validity were examined. Finally, multivariate poisson regressions investigated longitudinal predictors of CAP in mothers.
Results:
A previously established six-factor structure was confirmed for mothers but not fathers. CFA failed for fathers due to large numbers of variables with zero variance. For mothers, internal consistency and criterion validity were good. BCAPI score at follow-up was associated with baseline BCAPI score (β= 00.08), stress (β= 0.06), education (β=-0.19) and alcohol use(β= .58).
Conclusions:
Findings confirm the six-factor structure of the BCAPI among German mothers. The clinical use of the BCAPI in fathers is not recommended as it might produce data that are hard to interpret. Further research with fathers is needed to establish if this is due to limitations with this dataset or with the questionnaire.
Bei der Integration technischer Energiemanagementsysteme (tEnMS) in Automatisierungsanlagen fällt ein hoher Engineering-Aufwand an, besonders für die Steuerungsprogrammierung. Dieser Engineering-Aufwand ist für industrielle Anwender der Hauptgrund, integrierte tEnMS nicht einzusetzen. Im Rahmen des Forschungsprojektes „Integriertes Anlagenengineering zur Erhöhung der Energieeffizienz (IAE4)“ (Förderkennzeichen: ZN2948; Forschungsprofessur des Landes Niedersachsen/Volkswagenstiftung) wurde untersucht, wie sich dieser Engineering-Aufwand reduzieren lässt. Hierzu wurde ein Software-Werkzeug entwickelt, das die benötigten Steuerungsprogramme automatisch aus Engineering-Daten und Gerätebeschreibungsdateien generiert. Dieser Beitrag stellt die Ergebnisse des IAE4-Projektes vor.
The Logical Observation Identifiers, Names and Codes (LOINC) is a common terminology used for standardizing laboratory terms. Within the consortium of the HiGHmed project, LOINC is one of the central terminologies used for health data sharing across all university sites. Therefore, linking the LOINC codes to the site-specific tests and measures is one crucial step to reach this goal. In this work we report our ongoing efforts in implementing LOINC to our laboratory information system and research infrastructure, as well as our challenges and the lessons learned. 407 local terms could be mapped to 376 LOINC codes of which 209 are already available to routine laboratory data. In our experience, mapping of local terms to LOINC is a widely manual and time consuming process for reasons of language and expert knowledge of local laboratory procedures.
Background: Compromised immune function, associated with human immune deficiency virus (HIV) infection, is improved by antiretroviral therapy (ART) which also decreases bone mineral density (BMD), and possibly the quality of life (QoL). However, physical (aerobic/resistance) exercises, were reported to induce reverse effects in uninfected individuals and were appraised in the literature for evidence of similar benefits in people living with HIV/AIDS(PLWHA). The main study objective was to evaluate the impact of physical (aerobic and resistance) exercises on CD4+ count,
BMD and QoL in PLWHA.
Methods: A systematic review was conducted using the Cochrane Collaboration protocol. Searching databases, up to June 2017, only randomized control trials investigating the effects of either aerobic, resistance or a combination of both exercise types with a control/other intervention(s) for a period of at least 4 weeks among adults living with HIV, were included. Two independent reviewers determined the eligibility of the studies. Data were extracted and risk of bias (ROB) was assessed with the Cochrane Collaboration ROB tool. Meta-analyses were conducted using random effect models using the Review Manager (RevMan) computer software.
Results: Nineteen studies met inclusion criteria(n = 491 participants at study completion) comprising male and female with age range 22–66 years. Two meta-analyses across 13 sub-group comparisons were performed. However, there were no RCTs on the impact of physical exercises on BMD in PLWHA. The result showed no significant change in CD4+ count unlike a significant effect of 5.04 point (95%CI:-8.49,-3.74,p = 0.00001) for role activity limitation due to physical health (QoL sub-domain). Overall, the GRADE evidence for this review was of moderate quality.
Conclusions: There was evidence that engaging in moderate intensity aerobic exercises (55–85% Maximum heart rate-MHR), for 30–60 min, two to five times/week for 6–24 weeks significantly improves role activity limitation due to physical health problems, otherwise physical(aerobic or/and resistance) exercises have no significant effects on CD4+ count and other domains of QoL. Also, there is lack of evidence on the impact of exercises on BMD in PLWHA due to the paucity of RCTs. The moderate grade evidence for this review suggests that further research may likely have an important impact on our confidence in the estimate of effects and may change the estimate.
Background:
Promoting patient and occupational safety are two key challenges for hospitals. When aiming to improve these two outcomes synergistically, psychosocial working conditions, leadership by hospital management and supervisors, and perceptions of patient and occupational safety climate have to be considered. Recent studies have shown that these key topics are interrelated and form a critical foundation for promoting patient and occupational safety in hospitals. So far, these topics have mainly been studied independently from each other. The present study investigated hospital staffs’ perceptions of four different topics: (1) psychosocial working conditions, (2) leadership, (3) patient safety climate, and (4) occupational safety climate. We present results from a survey in two German university hospitals aiming to detect differences between nurses and physicians.
Methods:
We performed a cross-sectional study using a standardized paper-based questionnaire. The survey was conducted with nurses and physicians to assess the four topics. The instruments mainly consisted of scales of the German version of the COPSOQ (Copenhagen Psychosocial Questionnaire), one scale of the Copenhagen Burnout Inventory (CBI), scales to assess leadership and transformational leadership, scales to assess patient safety climate using the Hospital Survey on Patient Safety Culture (HSPSC), and analogous items to assess occupational safety climate.
Results:
A total of 995 completed questionnaires out of 2512 distributed questionnaires were returned anonymously. The overall response rate was 39.6%. The sample consisted of 381 physicians and 567 nurses. We found various differences with regard to the four topics. In most of the COPSOQ and the HSPSC-scales, physicians rated psychosocial working conditions and patient safety climate more positively than nurses. With regard to occupational safety, nurses
indicated higher occupational risks than physicians.
Conclusions:
The WorkSafeMed study combined the assessment of the four topics psychosocial working conditions, leadership, patient safety climate, and occupational safety climate in hospitals. Looking at the four topics provides an overview of where improvements in hospitals may be needed for nurses and physicians. Based on these results,
improvements in working conditions, patient safety climate, and occupational safety climate are required for health care professionals in German university hospitals – especially for nurses.
Mit der Hannoverschen Korruptionsskala Österreich-Version (kurz: HKS 38 Ö) kann die Einstellung zu Korruption gemessen werden. Die HKS 38 Ö ist eine Adaption der Hannoverschen Korruptionsskala (kurz: HKS 38) für den österreichischen Sprachraum. Die testtheoretische Überprüfung der HKS 38 Ö wird unter anderem in diesem Manual beschrieben. Die HKS 38 Ö umfasst 38 Items, die den Einstellungskomponenten kognitiv, affektiv und konativ zugeordnet werden können. Innerhalb dieses Manuals werden drei Datenerhebungen geschildert. In der ersten Datenerhebung (n = 1.617) wurde geprüft, ob die HKS 38 grundsätzlich für eine Anwendung in Österreich geeignet ist und ähnlich zuverlässige Messungen wie in Deutschland ermöglicht. Die Erfahrungen aus der ersten Datenerhebung – insbesondere die Hinweise von Testpersonen zur sprachlichen Verständlichkeit – führten zur Erstellung der HKS 38 Ö. Die HKS 38 Ö wurde im Rahmen einer zweiten Datenerhebung entsprechend der klassischen Testtheorie überprüft und auf Basis einer bevölkerungsrepräsentativen Telefonbefragung in Österreich (n ≈ 867) normiert. Neu im Vergleich zur ersten Auflage des Manuals ist die dritte Datenerhebung, in der die HKS 38 Ö für eine Befragung von Polizeischülern (n = 1.455) verwendet wurde. Auch die Daten der dritten Erhebung wurden testtheoretisch überprüft. Die HKS 38 Ö eignet sich zur Befragung von Testpersonen ab einem Alter von 18 Jahren.
Fragen gehören zu den wirkungsvollsten Mitteln, um Lernprozesse anzustoßen. Sie regen Studierende an, sich mit Inhalten auseinanderzusetzen, diese zu verstehen und ihr Wissen und Können zu zeigen. Fragen ermöglichen Lernenden genauso wie Lehrenden Feedback zum Lernstand zu erhalten. Eine „gute“ Frage zu erstellen, ist eine Herausforderung für alle Dozierenden, die ihnen in verschiedenen Lehrzusammenhängen begegnet:
• Klausurfragen (summatives Prüfen)
• Test- und Übungsaufgaben zur Selbsteinschätzung Studierender
• Test- und Übungsaufgaben als Lernfortschrittskontrolle
• Semesterbegleitende Übungsaufgaben zum kontinuierlichen Lernen
• Fragen für den Einsatz von Abstimmungssystemen (Audience-Response-Systeme)
Die vorliegende Handreichung bietet eine praktische Anleitung zur Erstellung guter Fragen im Antwort-Wahl-Verfahren (AWV). Unter guten Fragen verstehen wir Fragen hoher Qualität hinsichtlich der Gütekriterien Reliabilität, Validität und Objektivität. Den Schwerpunkt der Arbeit bilden allgemeine Hinweise zur Formulierung guter Fragen, wobei auch die fachdisziplinäre Sicht berücksichtigt wird.
Objective
To revise the German guidelines and recommendations for ensuring Good Epidemiological Practice (GEP) that were developed in 1999 by the German Society for Epidemiology (DGEpi), evaluated and revised in 2004, supplemented in 2008, and updated in 2014.
Methods
The executive board of the DGEpi tasked the third revision of the GEP. The revision was arrived as a result of a consensus-building process by a working group of the DGEpi in collaboration with other working groups of the DGEpi and with the German Association for Medical Informatics, Biometry and Epidemiology, the German Society of Social Medicine and Prevention (DGSMP), the German Region of the International Biometric Society (IBS-DR), the German Technology, Methods and Infrastructure for Networked Medical Research (TMF), and the German Network for Health Services Research (DNVF). The GEP also refers to related German Good Practice documents (e.g. Health Reporting, Cartographical Practice in the Healthcare System, Secondary Data Analysis).
Results
The working group modified the 11 guidelines (after revision: 1 ethics, 2 research question, 3 study protocol and manual of operations, 4 data protection, 5 sample banks, 6 quality assurance, 7 data storage and documentation, 8 analysis of epidemiological data, 9 contractual framework, 10 interpretation and scientific publication, 11 communication and public health) and modified and supplemented the related recommendations. All participating scientific professional associations adopted the revised GEP.
Conclusions
The revised GEP are addressed to everyone involved in the planning, preparation, execution, analysis, and evaluation of epidemiological research, as well as research institutes and funding bodies.
