Evaluation des AMP-Frameworks zur Optimierung einer komplexen Internetpräsenz
No full textGegenstand der hier vorgestellten Arbeit ist die Evaluation des AMP Frameworks für das Unternehmen TeamViewer GmbH. Dieses Thema wurde gewählt, um die aktuelle Performance-Leistung der Website zu optimieren und die Effektivität der eingesetzten Mittel zu steigern. Dazu wird der Ist-Zustand der Performance der Website mittels verschiedener Testarten und Tools aufgezeichnet, um eine mögliche Steigerung der Performance durch den Einsatz des AMP Frameworks ableiten zu können. Daher werden die Besonderheiten des Frameworks und verschiedene Arten der Implementierung aufgezeigt. Um die Integration des AMP Frameworks in das bestehende System der TeamViewer GmbH, welches durch Wordpress unterstützt wird, möglich zu machen, werden Details dazu festgehalten und bewertet. Anhand eines Proof of Concepts (PoC) wird gezeigt, dass die Integration des Frameworks möglich wäre. Die Evaluation der Tests mit integriertem AMP Framework zeigt, dass der Einsatz dieses eine Steigerung in der Performance bedeuten würde. Die Arbeit zeigt damit, dass die Verwendung des AMP Frameworks der TeamViewer GmbH nachhaltige Vorteile verschaffen würde. Diese reichen von einem gesteigerten Nutzerengagement und Interesse, über erhöhte Besucherzahlen auf der Website bis hin zu potenziell mehr Verkäufen der Software. Dabei ist der Entwicklungsaufwand, der benötigt würde, um die komplette Website mit AMP auszuliefern und eine teilweise Abhängigkeit von Google, nicht zu vernachlässigen. In der Praxis würde sich die Integration des AMP Frameworks jedoch auf lange Sicht lohnen, da die Kosten bei einer teilweisen Implementierung auf ausgewählten Seiten relativ gering ausfallen und der Gewinn durch die Performance Steigerung hoch zu bewerten ist. Zukünftige Forschung zu diesem Thema könnte in der Erstellung einer Kosten- Nutzenanalyse der vollständigen Implementierung des Frameworks erfolgen, da diese genau zeigen würde, ob der Nutzen des Frameworks den Entwicklungsaufwand übersteigt. Mit dieser Analyse könnten genauere Aussagen zu einer vollständigen Integration des Frameworks getroffen werden

Digital Sex Education: Availability and Quality of German Apps for Sexual Health Promotion
No full textIntroduction: German school curricula cannot entirely cover the contents of comprehensive sex education. An app targeting sexual health and sex education overall could support adolescents in their search for information as well as educators in their teaching.
Objectives: This systematic review aims to examine the quality and content of German apps currently available in Google Play and the App Store which could be used in sex education and in sexual health promotion.
Methods: Both app stores were screened using a web-crawler. We evaluated the quality of the identified apps using the German version of the “Mobile Application Rating Scale” MARS-G). Furthermore, the extent to which the apps can support comprehensive sex education in accordance with the (World Health Organization (WHO) and Federal Centre for Health Education (BzgA) was analyzed.
Results: Out of 7 318 screened apps, six met the inclusion criteria. The overall quality of the apps was an average of M = 3.54 (SD = 0.65, min = 2.64, max = 4.45). The app “Bill Sanders” achieved results in all subdimensions of the MARS-G that were at the least acceptable. The app “Only Human”, developed by the psychosocial AIDS counseling center of the Caritas in Munich, stood out positively and covered almost all topics of sex education.
Conclusion: German apps targeting sex education and sexual health were shown to be of medium quality. By means of the MARS-G, it became apparent that generally suitable apps have specific deficits, especially in terms of functionality, aesthetics, and subjective quality. The shortcomings identified should first of all be remedied in order to subsequently conduct scientific field evaluations examining the effectiveness of these apps. So far, scientific studies of this kind have not been conducted. The use of these apps can thus only be recommended with significant limitations
“Help in a Heartbeat?”: A Systematic Evaluation of Mobile Health Applications (Apps) for Coronary Heart Disease
No full textFor patients with coronary heart disease (CHD) lifestyle changes and disease management are key aspects of treatment that could be facilitated by mobile health applications (MHA). However, the quality and functions of MHA for CHD are largely unknown, since reviews are missing. Therefore, this study assessed the general characteristics, quality, and functions of MHA for CHD. Hereby, the Google Play and Apple App stores were systematically searched using a web crawler. The general characteristics and quality of MHA were rated with the Mobile Application Rating Scale (MARS) by two independent raters. From 3078 identified MHA, 38 met the pre-defined criteria and were included in the assessment. Most MHA were affiliated with commercial companies (52.63) and lacked an evidence-base. An overall average quality of MHA (M = 3.38, SD = 0.36) was found with deficiencies in information quality and engagement. The most common functions were provision of information and CHD risk score calculators. Further functions included reminders (e.g., for medication or exercises), feedback, and health management support. Most MHA (81.58) had one or two functions and MHA with more features had mostly higher MARS ratings. In summary, this review demonstrated that a number of potentially helpful MHA for patients with CHD are commercially available. However, there is a lack of scientific evidence documenting their usability and clinical potential. Since it is difficult for patients and healthcare providers to find suitable and high-quality MHA, databases with professionally reviewed MHA are required
Measuring the Cognitive Complexity in the Comprehension of Modular Process Models
Full text linkModularization in process models is a method to cope with the inherent complexity in such models (e.g., model size reduction). Modularization is capable to increase the quality, the ease of reuse, and the scalability of process models. Prior conducted research studied the effects of modular process models to enhance their comprehension. However, the effects of modularization on cognitive factors during process model comprehension are less understood so far. Therefore, this paper presents the results of two exploratory studies (i.e., a survey research study with N = 95 participants; a follow-up eye tracking study with N = 19 participants), in which three types of modularization (i.e., horizontal, vertical, orthogonal) were applied to process models expressed in terms of the Business Process Model and Notation (BPMN) 2.0. Further, the effects of modularization on the cognitive load, the level of acceptability, and the performance in process model comprehension were investigated. In general, the results revealed that participants were confronted with challenges during the comprehension of modularized process models. Further, performance in the comprehension of modularized process models showed only a few significant differences, however, the results obtained regarding the cognitive load revealed that the complexity and concept of modularization in process models were misjudged initially. The insights unraveled that the attitude towards the application and the behavioral intention to apply modularization in process model is still not clear. In this context, horizontal modularization appeared to be the best comprehensible modularization approach leading to a more fine-grained comprehension of respective process models. The findings indicate that alterations in modular process models (e.g., change in the representation) are important to foster and enable their comprehension. Finally, based on our results, implications for research and practice as well as directions for future work are discussed in this paper
How Healthcare Professionals Comprehend Process Models - An Empirical Eye Tracking Analysis
Full text linkDigitization is advancing rapidly in many prevalently analogue domains such as healthcare. For the latter
domain, the synergies with modern information technologies (IT)have become an integral part regarding communication and
collaboration. For this reason, a comprehensible language is of importance in order to allow for a frictionless exchange of information between domain experts. The Business Process Model and Notation (BPMN) 2.0 represents a promising notation that may be applied as lingua franca. Although BPMN 2.0 is widespread and applied by experts in business and industry, little experience exists on how BPMN 2.0 is adopted in healthcare. In order to assess how BPMN 2.0 is deployed in healthcare, we conducted a preliminary eye tracking study, in which n = 16 professionals from healthcare comprehended a particular BPMN 2.0 process
model. The results indicate that BPMN 2.0 might be a candidate for a lingua franca to foster the comprehensible exchange of information as well as collaboration between healthcare and I
Downstream Application of Persuasive Design and Usability Engineering Methods to Health Information Platforms
No full textAntibiotic resistance is a global health crisis but careful usage of medicine might reduce the problem. One way to achieve this is to spread resistance and guideline information using eHealth platforms. In this work, downstream application of usability engineering and persuasive design methods were combined to create the Antibiotic Treatment Recommender (ATR), an enhanced version of the eHealth website INFECT. Different design processes were analyzed and combined to ensure both usability and persuasion. A qualitative study was conducted to compare the results. This led to an understanding of the different needs of the target groups. While some users still preferred INFECT, the new ATR website was able to fulfill the requirements, satisfy most users, and offer promising opportunities for additional functionality
