T2 - Information and Communication Technology: 13th International Symposium, SOICT 2024, Danang, Vietnam, December 13–15, 2024, Proceedings, Part II N2 - Advances in genomic research have created new privacy challenges. This scoping review analyzes the risks associated with the processing, storage, and sharing of genomic data including epigenetics, and examines current privacy protection strategies. It also attempts to identify research gaps in this area. Using the PRISMA methodology, 37 relevant studies were identified and analyzed. The results of the risk assessment can be grouped into four main themes: Risks posed by processing of functional genomic data, sharing of genomic data, patient (re-)identification, and dividuality, i.e. the extending of privacy risks to blood relatives. The identified risk mitigation strategies were systematically categorized into five classes: pre-release measures, governance, secure data processing and exchange, access restriction and transparency, anonymization and masking. However, there are some important research gaps that still need to be addressed. The current literature neglects to assess the likelihood of potential breaches and tends to focus only on assessing possible scenarios of privacy risks. It also mainly fails to assess the role of contextualized data and the effectiveness of policies and governance systems with respect to privacy risks.

However, the adoption of EHR systems differs among countries and so does the way the decision to par-ticipate in EHRs is presented. Nudging is a concept that deals with influencing human behaviour within the research streamof behavioural economics. In this paper, we focus on the effects of the choice architecture on the decision for the adoption ofnational EHRs. Our study aims to link influences on human behaviour through nudging with the adoption of EHRs to inves-tigate how choice architects can facilitate the adoption of national information systems. Methods: We employ a qualitative explorative research design, namely the case study method. Using theoretical sampling,we selected four cases (i.e., countries) for our study: Estonia, Austria, the Netherlands, and Germany. We collected and ana-lyzed data from various primary and secondary sources: ethnographic observation, interviews, scientific papers, homepages,press releases, newspaper articles, technical specifications, publications from governmental bodies, and formal studies. Results: The findings from our European case studies show that designing for EHR adoption should encompass choice archi-tecture elements (i.e., defaults), technical elements (i.e., choice granularity and access transparency), and institutional ele-ments (i.e., regulations for data protection, information campaigns, and financial incentives) in combination. Conclusions: Our findings provide insights on the design of the adoption environments of large-scale, national EHR systems.Future research could estimate the magnitude of effects of the determinants.

Insbesondere darf der technische Betreiber des Servers, der die Daten speichert, keinen Zugriff erlangen. Es kann jedoch keine verlässliche Aussage dahingehend getroffen werden, ob die heute eingesetzten kryp-tographischen Algorithmen in 30 oder 40 Jahren die Vertraulichkeit der medizinischen Daten weiterhin gewährleisten. Es wird ein Verfahren vorgestellt, welches das Problem der langfristigen Sicherheit von verschlüsselt gespeicherten medizinischen Daten aus kryptographischer Sicht löst. Die Anwendung des Verfahrens wird am Beispiel einer nach den derzeit bekannten gematik-Spezifikationen definierten Infrastruktur veranschaulicht. Es wird von einer getrennten Speicherung von verschlüsselten medizinischen Daten und Schlüsselmaterial ausgegangen. Die Daten werden an der Datenquelle (Konnektor, z.B. eines Arztes) mit einem Einmalblock (One Time Pad, OTP) verschlüsselt. Sie sind damit beweisbar sicher verschlüsselt, weil das One-Time-Pad-Verschlüsselungsverfahren beweisbar „perfekt geheim“ ist. Der OTP-Schlüssel wird mit einem symmetrischen Schlüssel verschlüsselt, der wiederum mit den asymmetrischen Schlüsseln aller Zugriffsberechtigten verschlüsselt wird. Die kryptographische, technische und organisatorische Sicherheit des Verfahrens sowie seine Voraussetzungen und Kosten werden analysiert.

In modern health services data protection is essential. But there are also other important security objectives, such as integrity and authenticity of medical data and health services, as their breach can potentially lead to life threatening conditions. State of the art security mechanisms are necessary to protect medical data and services and prevent attacks known as “hacking”. They should include in particular cryptography, as you can usually rely on mathematics, more than in software security and access control mechanisms. As patients normally cannot assess the security of a service, security audits or certifications of health services should be provided to generate trust and confidence.

For the first time, this year’s challenge was organized as a cooperation between Technische Universität Dresden, GlobalFoundries, and ScaDS.AI Dresden/Leipzig. The Challenge’s participants were given real-world production and energy data from the semiconductor manufacturer GlobalFoundries and had to solve the problem of predicting the energy consumption for production equipment. The usage of real-world data gave the participants a hands-on experience of challenges in Big Data integration and analysis. After a leaderboard-based preselection round, the accepted participants presented their approach to an expert jury and audience in a hybrid format. In this article, we give an overview of the main points of the Data Science Challenge, like organization and problem description. Additionally, the winning team presents its solution.

Quant. Spectrosc. Radiat. Transfer 19 (1978) 509–516] is investigated. Various optimizations for the algorithm are discussed. In many applications, where these functions have to be calculated for a large x grid with constant y, an implementation using real arithmetic and factorization of invariant terms is especially efficient.

The study focused on one of the most challenging parts in this domain: the generation of an object model for a software product based on a requirements specification. During their training, software engineers are taught different techniques to solve this task. One of these techniques is the noun/verb analysis. However, it is still unclear to what extent novice and expert programmers are making use of it. Ideally, the noun/verb analysis works as a heuristic and helps programmers to make fast and accurate decisions. Participants in the study were 40 software programmers at four levels of expertise (novices, intermediates, experienced rogrammers, experts). They were presented with ten decision tasks. In each task, participants read a requirement specification and then had to choose one out of three presented class diagrams that they considered the best solution. During the task, their eye movements were recorded. Results show that all participants used the noun/verb analysis as a heuristic. Programmers with higher levels of expertise, however, outperformed programmers with lower levels of expertise. Interestingly, the more experienced programmers were not following the noun/verb analysis in a blindfolded way. They realised that the noun/verb analysis would produce diagrams, but a skilled software architect would not model them in this way. Instead they created their models in a way that they perceived as more logical and realistic Y1 - 2019 UR - https://earli.org/sites/default/files/2019-09/BOA-2019.pdf PB - RWTH Aachen ER - TY - CHAP A1 - Soska, Alexander A1 - Schumm, Michael A1 - Joseph, Saskia A1 - Reschke, Michael A1 - Mottok, Jürgen A1 - Niemetz, Michael A1 - Schroll-Decker, Irmgard T1 - Comparison of Frontal Lecture and Workshop Learning Arrangements in a Software Engineering Education Project T2 - 2014 IEEE Global Engineering Education Conference (EDUCON), Istanbul, Turkey N2 - The increase in complexity of software and its creation over the last decades requires an increase in the quality of the education of software engineering professionals. The number of Universities which answer this call by replacing or extending lectures with simulated software projects is constantly rising. However, the question how to best transfer new technological knowledge needed to be successful within this projects to the students remains open. Therefore this paper will present a comparison between the classical frontal lecture and a modern workshop learning arrangement used within these projects. By the use of workshops not only the knowledge transfer but also the acquisition of personal and social competences will be facilitated. Furthermore positive experiences with workshops at university level will support life-long learning.

We present a novel method for tracking this otherwise invisible evolution of software changes on mailing lists by connecting all early revisions of changes to their final version in repositories. Since artefact modifications on mailing lists are communicated by updates to fragments (i.e., patches) only, identifying semantically similar changes is a non-trivial task that our approach solves in a language-independent way. We evaluate our method on high-profile open source software (OSS) projects like the Linux kernel, and validate its high accuracy using an elaborately created ground truth. Our approach can be used to quantify properties of OSS development processes, which is an essential requirement for using OSS in reliable or safety-critical industrial products, where certifiability and conformance to processes are crucial. The high accuracy of our technique allows, to the best of our knowledge, for the first time to quantitatively determine if an open development process effectively aligns with given formal process requirements.

To address this challenge, some IT organizations have adopted Lean Management (LM). Although LM is a standard production mode in manufacturing, it is less familiar to IT organizations. The purpose of this paper is to identify 12 lessons learned from companies who implemented LM in their IT organization (Lean IT) to free up their IT resource capacity from existing day-to-day operations so they could use it to enable their digitization strategy. Design/methodology/approach A case study of two major international companies from different industries. Data were collected from 25 structured interviews. Findings The lessons learned provide insights into how these companies implemented Lean IT, the potential outcomes they aimed for, what they did to achieve those outcomes, how they facilitated the implementation of Lean IT, and restrictions they encountered during the implementation. Research limitations/implications The findings are based on a limited range of IT organizations. Practical implications The lessons learned inform those implementing Lean IT because they explain how companies have implemented Lean IT to facilitate digitization and the benefits and pitfalls they encountered. A comparison of Lean IT and Lean Production shows that LM is transferable to IT organizations if domain specific requirements are respected. Originality/value This paper reports the unique experience of companies implementing Lean IT, which can inform other companies in a similar situation.

Er ergänzt damit vorhergehende akademische Studien. Es zeigt sich, dass unter Praktikern der Eindruck vorherrscht, dass IT-Abteilungen unter zunehmendem Druck stehen, schneller auf sich ändernde Anforderungen aus den Fachbereichen reagieren zu müssen. Können IT-Abteilungen diesen Erwartungen nicht entsprechen, beschaffen sich Fachbereiche und Nutzer selbst Lösungen in Form von Schatten-IT. Als mögliche Antwort darauf kann sich die IT-Abteilung agiler organisieren und die IT-Architektur im Unternehmen modernisieren. Eine weitere Möglichkeit besteht darin, sich das innovative Potenzial von Schatten-IT zunutze zu machen und deren Umsetzung aktiv durch organisatorische und technische Maßnahmen zu unterstützen. IT-Sicherheitsmanagement und technische Schutzmechanismen können helfen, die so entstandenen Lösungen abzusichern und die Risiken zu minimieren. Nach vorherrschender Ansicht entwickelt sich die IT-Abteilung als Konsequenz aus all diesen Maßnahmen zu einem nutzerorientierten, internen Service-Provider und strategischen Partner für die Fachbereiche.

Lean Management in IT-Organisationen (Lean IT) ist dahingegen in der Praxis weniger verbreitet und in der Wissenschaft kaum erforscht. Dieser Beitrag aggregiert und erweitert die Ergebnisse mehrerer Forschungsarbeiten. Dabei werden vorrangig zwei Aspekte diskutiert: (1) Ein mögliches Einführungsmodell für Lean IT. Dieses verknüpft fünf Rollen (Sponsor, Programmleiter, Navigator, Linienführungskraft und Linienexperte) mit vier Phasen (Vorbereitung, Analyse, Gestaltung und Implementierung). (2) Besondere Herausforderungen für Linienführungskräfte, die aufgrund der „bottom up“-Ausrichtung bei Lean-IT-Einführungen stark gefordert werden. Neben einer klaren Vision für die Organisationseinheit und dem Verständnis, an welcher Stelle Lean IT die Organisationseinheit konkret unterstützen kann, benötigen sie Offenheit, Veränderungswillen und die Bereitschaft Verantwortung an Mitarbeiter zu delegieren. Außerdem sollten sie über ein ausreichendes Zeitbudget für die Einführung verfügen, um ihrer gestaltenden und qualitätssichernden Funktion nachkommen zu können.

This paper presents a comprehensive view of the field of study from a managerial point of view. It provides a consolidated view of the field of study between 2010 and 2013 based on a manual search comprising 69 selected journals and 9 conferences, as well as a search using 6 journal databases. The literature review ensures continuity of research by connecting to a comprehensive literature analysis covering the years 1999 to 2009. This way it consolidates and critically reflects the state of the research of the last 14 years. Overall, we compiled 95 relevant publications originating from leading IS journals and IS conference proceedings. The results indicate that IS offshoring research is largely non-theory based, using almost entirely empirical data and interpretive research methods and -to a smaller extent -positivist research designs. The ISO research of the last 14 years focuses on the implementation stages "how" and "outcome" while the pre-implementation-stages “why”, “what”, and “which” are comparatively sparsely researched. Future studies should apply a more theory-driven approach with a greater attention on pre-implementation aspects of information systems offshoring. In addition, future research should investigate the special nature of near- and onshoring, captive offshoring as well asagile (project) management techniques suitable for ISO.

While there is much research on information systems outsourcing, the topic of backsourcing information systemsis still an emerging research area. Therefore, ourpaper aims to explore and synthesizethe existing literature on information systemsbacksourcing, since there is no exhaustiveliteraturereview of the state of the research to our knowledge available yet. In this paper, wecreate a framework to structure the existing research along the overallbacksourcing process. We identifydifferent motivators, such asexpectation gaps, orinternal and external organizational changes, leading towards a backsourcing decision, and factors positively or negatively influencing this decision. Additionally, we derive implementation success factors based on the existing literature to guide companies through the backsourcing process.We also differentiate the term backsourcing from related, sometimes synonymously used terms, by emphasizing the change of ownership back to the company of originas the main criterion.Additionally, we discuss opportunities for future research in the field of information systems backsourcing.

To date, however, academic literature has presented surprisingly little information about the application of Lean Management in Information Technology (IT) organizations, or what is called Lean IT. Drawing upon an empirical qualitative case study of the IT departments of two multinational companies, in this paper we identify change management lessons learned for Lean IT implementations, as well as seven characteristics of a corresponding change management approach. As an extension of our work, researchers should validate and expand our initial findings, preferably in a quantitative setting.
