The Why of Cloud Computing Delivery Model Selection BT - Vignettes on the Post-Adoption of Cloud Computing T2 - Proceedings of the 54th Hawaii International Conference on System Sciences, 2021 N2 - Most large-scale organizations adopted Cloud Computing (CC) on a company level in recent years. Managers now face the challenge to appropriately implement CC "operationally", i.e., for information systems (ISs). We refer to this as post-adoption, addressing the extent of technology usage after adoption. Specifically, managers need to choose among the CC delivery models Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-asa-Service (SaaS). We differentiate the determinants of this post-adoption decision for IaaS, PaaS, and SaaS. Based on this analysis, we derive criteria that guide managers' delivery model selection: Adopt 1) IaaS for ISs requiring flexibility and reduced time to market, 2) PaaS to access specialized resources, and 3) SaaS to focus on core competencies. Moreover, we analyze the impact on the CC strategy and postulate them as recommendations: I) acknowledge the interplay between governance and time-to-market, II) realize cost savings on company level, and III) consider strategically important ISs for CC.

Injuries to muscles of the thigh are common in amateur and professional football, representing almost a third of all injuries. These injuries occur primarily in non-contact situations and from overuse. They can lead to a range of costs, including financial costs associated with treatment as well as those associated with long-term recovery, and absence from training and/or competition. Further, there is a high risk of injury recurrence and subsequent injury. Y1 - 2020 ER - TY - GEN A1 - Melzner, Maximilian A1 - Pfeifer, Christian A1 - Alt, V.

However to the best of the authors knowledge no complete convergence analysis exists for ADAM. The contribution of this paper is a method for the local convergence analysis in batch mode for a deterministic fixed training set, which gives necessary conditions for the hyperparameters of the ADAM algorithm. Due to the local nature of the arguments the objective function can be non-convex but must be at least twice continuously differentiable. Then we apply this procedure to other adaptive gradient descent algorithms and show for most of them local convergence with hyperparameter bounds.

We aimed to research into the impact of high offset (HO) and standard stems on postoperative ROM. 121 patients received cementless THA through a minimally-invasive anterolateral approach. A 360° hip ROM analysis software calculated impingement-free hip movement based on postoperative 3D-CTs compared to ROM values necessary for activities of daily living (ADL). The same model was then run a second time after changing the stem geometry between standard and HO configuration with the implants in the same position. HO stems showed higher ROM for all directions between 4.6 and 8.9° (p < 0.001) compared with standard stems but with high interindividual variability. In the subgroup with HO stems for intraoperative offset restoration, the increase in ROM was even higher for all ROM directions with values between 6.1 and 14.4° (p < 0.001) compared to offset underrestoration with standard stems. Avoiding offset underrestoration resulted in a higher amount of patients of over 20% for each ROM direction that fulfilled the criteria for ADL (p < 0.001). In contrast, in patients with standard stems for offset restoration ROM did increase but not clinically relevant by offset overcorrection for all directions between 3.1 and 6.1° (p < 0.001). Offset overcorrection by replacing standard with HO stems improved ROM for ADL in a low number of patients below 10% (p > 0.03). Patient-individual restoration of offset is crucial for free ROM in THA. Both over and underrestoration of offset should be avoided.

A1 - Dendorfer, Sebastian T1 - Torus obstacle method as a wrapping approach of the deltoid muscle group for humeral abduction in musculoskeletal simulation JF - Journal of Biomechanics N2 - Musculoskeletal models of the shoulder complex are valuable research aids to investigate tears of the supraspinatus and the resulting mechanical impact during abduction of the humerus. One of the major contributors to this motion is the deltoid muscle group and for this, an accurate modeling of the lines of action is indispensable. The aim of this work was to utilize a torus obstacle wrapping approach for the deltoids of an existing shoulder model and assess the feasibility of the approach during humeral abduction. The shoulder model from the AnyBody™ modeling system was used as a platform. The size of the tori is based on a magnetic resonance imaging (MRI) approach and several kinematic couplings are implemented to determine the trajectories of the tori during abduction. To assess the model behavior, the moment arms of the virtual muscle elements and the resultant glenohumeral joint reaction force (GHJF) were compared with reference data from the literature during abduction of the humerus in the range 20°–120°. The root mean square error for the anterior, lateral and posterior part between the simulated muscle elements and reference data from the literature was 3.9, 1.7 and 5.8 mm, respectively. The largest deviation occurred on the outer elements of the muscle groups, with 12.6, 10.4 and 20.5 mm, respectively. During abduction, there is no overlapping of the muscle elements and these are in continuous contact with the torus obstacles, thus enabling a continuous force transmission. This results in a rising trend of the resultant GHJF. The torus obstacle approach as a wrapping method for the deltoid muscles provides a guided muscle pathing by simultaneously approximating the curvature of the deltoid muscle. The results from the comparison of the simulated moment arms and the resultant GHJF are in accordance with those in the literature in the range 20°–120° of abduction. Although this study shows the strength of the torus obstacle as a wrapping approach, the method of fitting the tori according to MRI data was not suitable. A cadaver study is recommended to better validate and mathematically describe the torus approach.

It is an injurious type of sport with a focus on lower extremities and high psychological pressure during matches. The stressor is linked with injuries and an increased musculoskeletal loading. This study investigates the influence of cognitive stress on the load profile of the knee joint. Twelve professional youth soccer players performed highly dynamic runs with and without additional cognitive stress. The runs were analysed with a musculoskeletal simulation software. The data analysis shows no difference in knee joint reaction loading under additional mental stress compared to the baseline. Yet running times are significantly lower in the baseline. While there is no increase in the joint loads, the running times indicate an altered movement behaviour when the subjects are exposed to additional mental demand.

We trained an Artificial Intelligence (AI) system on the basis of deep artificial neural networks (deep learning) to differentiate between T1a and T1b Barrett’s cancer white-light images. Methods: Endoscopic images from three tertiary care centres in Germany were collected retrospectively. A deep learning system was trained and tested using the principles of cross-validation. A total of 230 white-light endoscopic images (108 T1a and 122 T1b) was evaluated with the AI-system. For comparison, the images were also classified by experts specialized in endoscopic diagnosis and treatment of Barrett’s cancer. Results: The sensitivity, specificity, F1 and accuracy of the AI-system in the differentiation between T1a and T1b cancer lesions was 0.77, 0.64, 0.73 and 0.71, respectively. There was no statistically significant difference between the performance of the AI-system and that of human experts with sensitivity, specificity, F1 and accuracy of 0.63, 0.78, 0.67 and 0.70 respectively. Conclusion: This pilot study demonstrates the first multicenter application of an AI-based system in the prediction of submucosal invasion in endoscopic images of Barrett’s cancer. AI scored equal to international experts in the field, but more work is necessary to improve the system and apply it to video sequences and in a real-life setting. Nevertheless, the correct prediction of submucosal invasion in Barret´s cancer remains challenging for both experts and AI.

To prove the consensus between the manual and automatic digital measurements, we evaluated the software by comparing the manual and automatic measurements of 46 breasts. Methods: Twenty-three patients who underwent reconstructive surgery for congenital breast asymmetry at our institution were examined and underwent 3D surface imaging. Per patient, 14 manual and 14 computer-based anthropometric measurements were obtained according to a standardized protocol. Manual and automatic measurements, as well as the previously proposed Symmetry Index (SI), were compared. Results: The Wilcoxon signed-rank test revealed no significant differences in six of the seven measurements between the automatic and manual assessments. The SI showed robust agreement between the automatic and manual methods. Conclusion: The present trial validates our method for digital anthropometry. Despite the discrepancy in one measurement, all remaining measurements, including the SI, showed high agreement between the manual and automatic methods. The proposed data bring us one step closer to the long-term goal of establishing robust instruments to evaluate the results of breast surgery.

Diese Arbeit beschäftigt sich mit der Entwicklung eines zentralen Blindleistungsregelsystems, bei dem Blindleistungsquellen auf Basis von „Optimal Power Flow“-Berechnungen über eine zentrale Recheninstanz angesteuert werden. Zum Einsatz kommt dabei ein Optimierungsalgorithmus, der auf Basis des aktuellen Netzzustandes (Spannungs- und Auslastungsreserven) und des aktuellen Blindleis-tungspotentials der Blindleistungsquellen einen bedarfsoptimalen Abruf koordiniert. Das zentrale Re-gelverfahren wird in Netzmodellen verschiedenartiger Mittelspannungsnetzgruppen und unterschiedli-cher Art und Anzahl von Blindleistungsquellen angewendet sowie im Hinblick auf variierende Zielvor-gaben und Randbedingungen evaluiert und diskutiert.

T1 - Standalone performance of artificial intelligence for upper GI neoplasia: a meta-analysis JF - Gut N2 - Objective: Artificial intelligence (AI) may reduce underdiagnosed or overlooked upper GI (UGI) neoplastic and preneoplastic conditions, due to subtle appearance and low disease prevalence. Only disease-specific AI performances have been reported, generating uncertainty on its clinical value. Design: We searched PubMed, Embase and Scopus until July 2020, for studies on the diagnostic performance of AI in detection and characterisation of UGI lesions. Primary outcomes were pooled diagnostic accuracy, sensitivity and specificity of AI. Secondary outcomes were pooled positive (PPV) and negative (NPV) predictive values. We calculated pooled proportion rates (%), designed summary receiving operating characteristic curves with respective area under the curves (AUCs) and performed metaregression and sensitivity analysis. Results: Overall, 19 studies on detection of oesophageal squamous cell neoplasia (ESCN) or Barrett's esophagus-related neoplasia (BERN) or gastric adenocarcinoma (GCA) were included with 218, 445, 453 patients and 7976, 2340, 13 562 images, respectively. AI-sensitivity/specificity/PPV/NPV/positive likelihood ratio/negative likelihood ratio for UGI neoplasia detection were 90% (CI 85% to 94%)/89% (CI 85% to 92%)/87% (CI 83% to 91%)/91% (CI 87% to 94%)/8.2 (CI 5.7 to 11.7)/0.111 (CI 0.071 to 0.175), respectively, with an overall AUC of 0.95 (CI 0.93 to 0.97). No difference in AI performance across ESCN, BERN and GCA was found, AUC being 0.94 (CI 0.52 to 0.99), 0.96 (CI 0.95 to 0.98), 0.93 (CI 0.83 to 0.99), respectively. Overall, study quality was low, with high risk of selection bias. No significant publication bias was found. Conclusion: We found a high overall AI accuracy for the diagnosis of any neoplastic lesion of the UGI tract that was independent of the underlying condition. This may be expected to substantially reduce the miss rate of precancerous lesions and early cancer when implemented in clinical practice.

Betrachtet man allerdings die digitale Wettbewerbsfähigkeit, so lässt sich feststellen, dass deutsche Unternehmen nur wenig in digitale Technologien investieren und im OECD-Vergleich einen der letzten Plätze belegen (vgl. Deloitte, 2017, S. 30). Speziell der Bausektor weist hierbei großen Nachholbedarf auf, wie beispielsweise eine Studie von von Both aufzeigt. Von Both (2013) definiert die Implementierung der neuen Arbeitsmethodik für das digitale Bauen, das sog. Building Information Modeling (BIM), in sieben Phasen. Während Großbritannien in der fünften Phase „der Versuchsphase“ ist und sich Korea sogar bereits in der letzten Phase „der Integrationsphase“ befindet, akzeptiert Deutschland erst die neue Arbeitsmethodik (Phase 3) und beginnt die Notwendigkeit zu realisieren (Phase 4).

T2 - Wissensorganisation und Edutainment: Wissen im Spannungsfeld von Gesellschaft, Gestaltung und Industrie N2 - Nicht nur in der wissenschaftlichen, sondern auch oder gerade in der öffentlichen Diskussion wird viel von der „Wissensgesellschaft“ gesprochen. Einmal davon abgesehen, dass dieser Ausdruck oftmals mit ganz verschiedenen Intentionen benutzt wird – so im Hinblick auf die Notwendigkeit, in der Arbeitswelt lebenslang zu lernen, auf die Wissensgeladenheit vieler neuer Produkte oder auf die Verlagerung von Bildungsprozessen von Schulen und Universitäten ins Internet –, ist bei genauerer Betrachtung nicht klar, wo Wissensgesellschaften existieren, im Entstehen begriffen sind oder entstehen könnten, d. h. welche Gesellschaften den Transformationsprozess von der XYZ- zur Wissensgesellschaft in der Vergangenheit schon vollzogen haben, gerade vollziehen oder in Zukunft vollziehen werden. Es ist auch nicht klar, ob es nur eine oder viele Wissensgesellschaften gibt, geben soll oder geben wird. Schon aus diesen wenigen Bemerkungen wird ersichtlich, dass die Rede von der (globalen) Wissensgesellschaft ähnlich wie jene von der Globalisierung alles andere als klar ist. In einem Überblick soll im Folgenden deshalb versucht werden, diese Unklarheiten zumindest ein wenig zu beseitigen. Es wird dabei deutlich, dass sich selbst nur lokale Wissensgesellschaften im Grunde allenfalls in statu nascendi befinden und eine globale Wissensgesellschaft noch in weiter Ferne liegt oder gar eine nicht zu realisierende Utopie darstellt. Zunächst wird der status quo beschrieben, also die große Ungleichheit in der Möglichkeit der Internetnutzung, global und auf das geografische Europa bezogen. Danach wird versucht, anzudeuten, welche Probleme gelöst werden müssten, damit diese Ungleichgewichtung abgebaut werden kann oder doch zumindest nicht noch größer wird. Zuletzt soll der Entwurf einiger Grundsätze aufgezeigt werden, die für die Gestaltung lokaler Wissensgesellschaften handlungsleitend sein sollten und meines Erachtens notwendige Bedingungen der Möglichkeit sowohl lokaler als auch globaler Wissensgesellschaften darstellen. Der damit verbundene normative Anspruch wird dabei mit der Annahme begründet, dass sich Informationen, Wissen und Bildung in der immer komplexer werdenden Welt zu Grundgütern entwickelt haben, ohne die auf der personalen Ebene ein gelungenes Leben kaum noch zu führen ist und ohne die auf der Ebene der Gemeinwesen eine Entwicklung ökonomisch benachteiligter Länder und Regionen beeinträchtigt oder gar verunmöglicht wird bzw. die schon hochindustrialisierten Staaten den bisher erreichten Lebensstandard nicht halten werden können.

Proceedings of the 6th International Conference of Computer Ethics: Philosophical Enquiries (CEPE2005) N2 - The coming years will be characterized by the development of mobile ICT that will enable con - sumers to use information and communication services everywhere and anytime. Technologies like GPRS, WLAN, or UMTS can be used stand-alone or in combination with other technologies like RFID or GPS to provide, for instance, location-aware services. Mobile ICT is to be expected to evolve to that what often is called Ambient Intelligence, Ubiquitous or Pervasive Computing. It is likely that such new technologies will affect personnel privacy because providing mobile ICT services inherits the identification and often the exact localization of users. In the following text we shall analyze possible threats of privacy. We will distinguish different dimensions or aspects of privacy to show how new technologies can affect them. After that, we shall argue that it is necessary to make a distinction of privacy and data protection: privacy primarily is a matter of social norms and data protection the realm of technical measurements. Additionally, we will provide some empirical evidence that users of the Internet make that distinction. Finally, we will claim that the right to privacy and privacy itself only can be protected if there are widely accepted social norms regarding privacy.

Volume II: Metaphysics and epistemology N2 - In this text I would like to make some remarks on the so called ‘Science Wars’ from a Critical Rationalist’s point of view. First I will describe the beginning of this war, which was given public awareness by Alan Sokal in 1996 publishing his text Transgressing the Boundaries. Toward a transformative Hermeneutics of Quantum Gravity in the postmodernist journal Social Text. In 1997 Alan Sokal, together with Jean Bricmont, again attacked postmodernist and poststructuralist scholars with the book Impostures Intellectuelles. I will describe the aims of their book and in addition portray briefly the postmodernist relativistic epistemology. Since Sokal and Bricmont identify Critical Rationalism as a source of that relativism, I then will show possible reasons for this reproach. I will reject their critique, since it is based on false estimations about Critical Rationalism but I also will show that there are some good reasons to criticize Critical Rationalism. As a kind of conclusion I will argue that in the future it is necessary that Critical Rationalists will dispute more offensively against postmodernist thinking to prevent a deepening of the gap between the humanities and science and because science is an important means to the improvement of our society.
