T1 - Influence of hormone replacement therapy on proteomic pattern in serum of postmenopausal women N2 - Objectives: Proteomics approaches to cardiovascular biology and disease hold the promise of identifying specific proteins and peptides or modification thereof to assist in the identification of novel biomarkers. Method: By using surface-enhanced laser desorption and ionization time of flight mass spectroscopy (SELDI-TOF-MS) serum peptide and protein patterns were detected enabling to discriminate between postmenopausal women with and without hormone replacement therapy (HRT). Results: Serum of 13 HRT and 27 control subjects was analyzed and 42 peptides and proteins could be tentatively identified based on their molecular weight and binding characteristics on the chip surface. By using decision tree-based Biomarker Patterns (TM) Software classification and regression analysis a discriminatory function was developed allowing to distinguish between HRT women and controls correctly and, thus, yielding a sensitivity of 100% and a specificity of 100%. The results show that peptide and protein patterns have the potential to deliver novel biomarkers as well as pinpointing targets for improved treatment. The biomarkers obtained represent a promising tool to discriminate between HRT users and non-users. Conclusion: According to a tentative identification of the markers by their molecular weight and binding characteristics, most of them appear to be part of the inflammation induced acute-phase response.

The comparison group (CG) included 92 asthmatic children and adolescents receiving standard medical treatments. Patients were aged between 8 and 16 years and were predominantly male. The health-related quality of life was measured with the German version of the "Paediatric Asthma Quality of Life Questionnaire." Interviews were carried out for IG 2 weeks before the commencement of their inpatient stay and 1 year after their stay ended. The same time schedule was carried out for CG. All patients reported a mild to moderate impairment of their quality of life. Girls described a slightly lower quality of life than boys. With increasing asthma severity, quality of life decreased. Inpatients described a lower quality of life than CG at enrollment. Inpatient rehabilitation resulted in a greater improvement of quality of life over time for IG than for CG. Gender and severity status had no effect on this time course. The only modestly affected quality of life may reflect the good adaptation to the disease and medical treatment. Children and adolescents in the IG recorded improvements in their quality of life. Differences in quality of life based on gender and disease severity were not shown to influence the improvements. In summary, inpatient rehabilitation results in an improvement of health-related quality of life.

However, Glg2p possesses an additional tyrosine residue, Tyr230 and therefore two potential autoglucosylation sites. Glucosylation of Glg2p was studied using both matrix-assisted laser desorption ionization and electrospray quadrupole time of flight mass spectrometry. Glg2p, carrying a C-terminal (His(6)) tag, was produced in Escherichia coli and purified. By tryptic digestion and reversed phase chromatography a peptide (residues 219-246 of the complete Glg2p sequence) was isolated that contained 4-25 glucosyl residues. Following incubation of Glg2p with UDPglucose, more than 36 glucosyl residues were covalently bound to this peptide. Using a combination of cyanogen bromide cleavage of the protein backbone, enzymatic hydrolysis of glycosidic bonds and reversed phase chromatography, mono- and diglucosylated peptides having the sequence PNYGYQSSPAM were generated. MS/MS spectra revealed that glucosyl residues were attached to both Tyr232 and Tyr230 within the same peptide. The formation of the highly glucosylated eukaryotic Glg2p did not favour the bacterial glycogen accumulation. Under various experimental conditions Glg2p-producing cells accumulated approximately 30% less glycogen than a control transformed with a Glg2p lacking plasmid. The size distribution of the glycogen and extractable activities of several glycogen-related enzymes were essentially unchanged. As revealed by high performance anion exchange chromatography, the intracellular maltooligosaccharide pattern of the bacterial cells expressing the functional eukaryotic transgene was significantly altered. Thus, the eukaryotic glycogenin appears to be incompatible with the bacterial initiation of glycogen biosynthesis Y1 - 2004 ER - TY - JOUR A1 - Ette, Ottmar T1 - Archeologies of Globalization : European Reflections on Two Phases of Accelerated Globalization in Cornelius de Pauw, Georg Forster, Guillaume-Thomas Raynal and Alexander von Humboldt Y1 - 2012 UR - http://cultureandhistory.revistas.csic.es/index.php/cultureandhistory/article/view/4/19 ER - TY - JOUR A1 - Wacker, Alexander A1 - von Elert, Eric T1 - Settlement pattern of the zebra mussel, Dreissena polymorpha, as a function of depth in Lake Constance N2 - Settlement on suitable substrata under favourable environmental conditions is an important factor for a successful recruitment of adult populations of Dreissena polymorpha. Therefore, the pattern of settlement of zebra mussel (Dreissena polymorpha) larvae at different depths was studied in Lake Constance. Maximum densities of larvae and newly settled juvenile mussels were observed at 4m depth, while only single settlement episodes were recorded at greater depths (15 m and 30 m). Temperature fluctuation was used as a surrogate parameter for internal seiches. Biotic and abiotic parameters were subjected to a principal component analysis (PCA). The tight coupling of the internal seiches, larval abundance and settlement at 4-m depth vs. the lack of coupling of the latter two variables at greater depths indicated that water currents transported settling larvae to the substrata at greater depth. Our data suggest that physical factors, such as boundary mixing and internal seiches, should be considered as sources of variability in settlement.

The focus is on their trip from Genève to Kabul that Ella Maillart and Annemarie Schwarzenbach made together in 1939/1940 and Nicolas Bouvier 1953/1954 with the artist Thierry Vernet. The comparison shows the strong connection between the journey and life and between ars vivendi and travel literature. This book also gives an overview of and organises the numerous terms, genres, and categories that already exist to describe various travel texts and proposes the new term travelling narration. The travelling narration looks at the text from a narratological perspective that distinguishes the author, narrator, and protagonist within the narration. In the examination, ten motifs could be found to characterise the travelling narration: Culture, Crossing Borders, Freedom, Time and Space, the Aesthetics of Landscapes, Writing and Reading, the Self and/as the Other, Home, Religion and Spirituality as well as the Journey. The importance of each individual motif does not only apply in the 1930s or 1950s but also transmits important findings for living together today and in the future.

Der Vergleich zeigt die enge Verbindung zwischen der Reise und dem Leben sowie zwischen ars vivendi und Reiseliteratur. Das Buch gibt einen Überblick über die zahlreichen Begriffe, Gattungen und Kategorien, die bereits zur Beschreibung verschiedener Reisetexte existieren, und schlägt den neuen Begriff der reisenden Erzählung „travelling narration“ vor. Die reisende Erzählung betrachtet den Text aus einer narratologischen Perspektive, die den Autor, Erzähler und Protagonisten innerhalb der Erzählung unterscheidet. In der Untersuchung konnten zehn Motive gefunden werden, die die reisende Erzählung charakterisieren: Kultur, Grenzüberschreitung, Freiheit, Zeit und Raum, Ästhetik der Landschaft, Schreiben und Lesen, das Selbst und / oder der Andere, Heimat, Religion und Spiritualität sowie die Reise. Die Bedeutung jedes einzelnen Motivs gilt nicht nur für die 1930er oder 1950er Jahre, sondern vermittelt auch wichtige Erkenntnisse für das Zusammenleben heute und in der Zukunft.

BT - Or, "Soll am Europäischen Wesen die Staatenimmunität genesen"? T2 - Remedies against immunity? N2 - This chapter argues not only that there is no European Sonderweg (or ‘special way’) when it comes to the law of state immunity but that there ought not to be one. Debates within The Hague Conference on Private International Law in the late 1990s and those leading to the adoption of the 2002 UN Convention on Jurisdictional Immunities of States, as well as the development of the EU Brussels Regulation on Jurisdiction and Enforcement, as amended in 2015, all demonstrate that state immunity was not meant to be limited by such treaties but ‘safeguarded’. Likewise, there is no proof that regional European customary law limits state immunity when it comes to ius cogens violations, as Italy and (partly) Greece are the only European states denying state immunity in such cases while the European Court of Human Rights has, time and again, upheld a broad concept of state immunity. It therefore seems unlikely that in the foreseeable future a specific European customary law norm on state immunity will develop, especially given the lack of participation in such practice by those states most concerned by the matter, including Germany. This chapter considers the possible legal implications of the jurisprudence of the Italian Constitutional Court for European military operations (if such operations went beyond peacekeeping). These implications would mainly depend on the question of attribution: if one where to assume that acts undertaken within the framework of military operations led by the EU were to be, at least also, attributable to the troop-contributing member states, the respective troop-contributing state would be entitled to enjoy state immunity exactly to the same degree as in any kind of unilateral military operations. Additionally, some possible perspectives beyond Sentenza 238/2014 are examined, in particular concerning the redress awarded by domestic courts ‘as long as’ neither the German nor the international system grant equivalent protection to the victims of serious violations of international humanitarian law committed during World War II. In the author’s opinion, strengthening the jurisdiction of international courts and tribunals, bringing interstate cases for damages before the International Court of Justice, as well as providing for claims commissions where individual compensation might be sought for violations of international humanitarian law would be more useful and appropriate mechanisms than denying state immunity.

First of all, the article will describe the current state of the International Criminal Court and the Rome Statue. Afterwards, the article analyses the Court’s efforts to deal with cases against third-country nationals and the challenges it is facing in that regard. In addition, the Court’s case law will be analyzed in order to determine an increasing ‘emancipation’ of the case law of the International Criminal Court from international humanitarian law. The second part of the paper will briefly discuss the role of domestic international criminal law and domestic courts in the further development and enforcement of international criminal law. As an example of the role that domestic courts may have in clarifying classic issues in international law, the judgment of the German Supreme Court of January 28, 2021 (3 StR 564/19), which deals with the status of costumary international law on functional immunity of State officials before domestic courts, shall be assessed.

Especially, extending life time of whole products or parts via remanufacturing is an promising approach to reduce waste. However, necessary cost-efficient assessment of the condition of the individual parts is challenging and assessment procedures are technically complex (e.g., scanning and testing procedures). Furthermore, these assessment procedures are usually only available after the disassembly process has been completed. This is where conceptualization, data acquisition and simulation of remanufacturing processes can help. One major constraining aspect of remanufacturing is reducing logistic efforts, since these also have negative external effects on the environment. Thus regionalization is an additional but in the end consequential challenge for remanufacturing. This article aims to fill a gap by providing an regional remanufacturing approach, in particular the design of local remanufacturing chains. Thereby, further focus lies on modeling and simulating alternative courses of action, including feasibility study and eco-nomic assessment.

One major challenge is that individuals often don’t recognize their tacit knowledge resources, while another is the reluctance to share one’s knowledge with others. Addressing these challenges, the authors present an application-oriented serious game-based haptic modeling approach for externalize tacit knowledge, which can be used to develop the first versions of business models based on tacit knowledge. Both conceptual and practical design fundamentals are presented based on elaborated theoretical approaches, which were developed with the help of a design science approach. The development of the research process is presented step by step, whereby we focused on the high accessibility of the presented research. Practitioners are presented with guidelines for implementing their serious game projects. Scientists benefit from starting points for their research topics of externalization, internalization, and socialization of tacit knowledge, development of business models, and serious games or gamification. The paper concludes with open research desiderata and questions from the presented research process.

Often conceived as positive, perfectionism can yield not only beneficial but also deleterious outcomes ranging from anxiety to burnout. In this proposal, we set out to investigate the role of the technology and, particularly, social media in individuals’ strivings for perfection. We lay down theoretical bases for the possibility that social media plays a role in the development of perfectionism. To empirically test the hypothesized relationship, we propose a comprehensive study design based on the experience sampling method. Lastly, we provide an overview of the planned analysis and future steps.

However, the same users readily disclose their data when requested by an online service. The dichotomy between privacy attitude and actual behaviour is commonly referred to as the “privacy paradox”. Over twenty years of research were not able to provide one comprehensive explanation for the paradox and seems even further from providing actual means to overcome the paradox. We argue that the privacy paradox is not just an instantiation of the attitude-behaviour gap. Instead, we introduce a new paradigm explaining the paradox as the result of attitude-intention and intentionbehaviour gaps. Historically, motivational goal-setting psychologists addressed the issue of intentionbehaviour gaps in terms of the Rubicon Model of Action Phases and argued that commitment and volitional strength are an essential mechanism that fuel intentions and translate them into action. Thus, in this study we address the privacy paradox from a motivational psychological perspective by developing two interventions on Facebook and assess whether the 287 participants of our online experiment actually change their privacy behaviour. The results demonstrate the presence of an intentionbehaviour gap and the efficacy of our interventions in reducing the privacy paradox.

The ability to speed up the transfer of knowledge between any kind of knowledge carriers in business processes with AR techniques can lead to a huge competitive advantage, for instance in manufacturing. This includes the transfer of person-bound knowledge as well as externalized knowledge of physical and virtual objects. The contribution builds on a time-dependent knowledge transfer model and conceptualizes an adaptable, AR-based application. Having the intention to accelerate the speed of knowledge transfers between a manufacturer and an information system, empirical results of an experimentation show the validity of this approach. For the first time, it will be possible to discover how to improve the transfer among knowledge carriers of an organization with knowledge-driven information systems (KDIS). Within an experiment setting, the paper shows how to improve the quantitative effects regarding the quality and amount of time needed for an example manufacturing process realization by an adaptable KDIS.

In recent years, digital technologies have transformed business and society, impacting all sectors of the economy and a wide variety of areas of life. Digitization is leading to rapidly growing volumes of data with great economic potential. Data, in its raw or unstructured form, has become an important and valuable economic asset, and protection of raw data has become a crucial subject for the intellectual property community. As legislators struggle to develop a settled legal regime in this complex area, this invaluable handbook will offer a careful and dedicated analysis of the legal instruments and remedies, both existing and potential, that provide such protection across a wide variety of national legal systems. What’s in this book: Produced under the auspices of the International Association for the Protection of International Property (AIPPI), more than forty active specialists of the association from twenty-three countries worldwide contribute national chapters on the relevant law in their respective jurisdictions. The contributions thoroughly explain how each country approaches such crucial matters as the following: if there is any intellectual property right available to protect raw data; the nature of such intellectual property rights that exist in unstructured data; contracts on data and which legal boundaries stand in the way of contract drafting; liability for data products or services; and questions of international private law and cross-border portability. Each country’s rules concerning specific forms of data – such as data embedded in household appliances and consumer goods, criminal offence data, data relating to human genetics, tax and bank secrecy, medical records, and clinical trial data – are described, drawing on legislation, regulation, and case law.

Network interfaces (called host channel adapters) provide transport layer services over connections and datagrams in reliable or unreliable manner. Additionally, InfiniBand supports remote direct memory access (RDMA) primitives that allow for one- sided communication. Using server load balancing together with a high performance cluster makes it possible to build a fast, scalable, and reliable service infrastructure. We have designed and implemented a scalable load balancer for InfiniBand clusters called SLIBNet. Our investigations show that the InfiniBand architecture offers features which perfectly support load balancing. We want to thank the Megware Computer GmbH for providing us an InfiniBand switch to realize a server load balancing testbed.

By now, artificial intelligence (AI) methods were used in knowledge management (KM) for knowledge discovery, for the reinterpreting of information, and recent works focus on the studying of different AI technologies implementation for knowledge management, like big data, ontology-based methods and intelligent agents [1]. However, a lack of holistic management approach is present, that considers artificial systems as knowledge bearers. The paper therefore designs a new kind of KM approach, that integrates the technical level of knowledge and manifests as Neuronal KM (NKM). Superimposing traditional KM approaches with the NKM, the Symbiotic Knowledge Management (SKM) is conceptualized furthermore, so that human as well as artificial kinds of knowledge bearers can be managed as symbiosis. First use cases demonstrate the new KM, NKM and SKM approaches in a proof-of-concept and exemplify their differences.

Prior studies have shown that those who disclose health-related information across OSNs often tend to regret it and delete their publications afterwards. Hence, deleted posts containing sensitive data can be seen as manifestations of online regrets. In this work, we present an analysis of deleted content on Twitter during the outbreak of the COVID-19 pandemic. For this, we collected more than 3.67 million tweets describing COVID-19 symptoms (e.g., fever, cough, and fatigue) posted between January and April 2020. We observed that around 24% of the tweets containing personal pronouns were deleted either by their authors or by the platform after one year. As a practical application of the resulting dataset, we explored its suitability for the automatic classification of regrettable content on Twitter.

This will be based on the knowledge modelling and description language (KMDL(R)) that enables the modelling and analysis of knowledge intensive business processes. First the basic elements of the modelling technique are described, presenting the concept and the description language. Furthermore it is shown how the KMDL(R) process models can be used as a basis for the team building component. Therefore, an algorithm was developed that is able to propose a team composition for a specific task by analyzing the knowledge and skills of the employees, which will be contrasted to the process requirements. This can be used as guidance for team building decisions.

The increasing conclusion of such legally non-binding instruments in addition to their flexibility, however, also leads to uncertainties in international relations. Against this background, this article deals with possible indirect legal consequences produced by MOUs. It discusses the different legal mechanisms and avenues that may give rise to secondary legal effects of MOUs through a process of interaction with and interpretation in line with other (formal) sources of international law. The article further considers various strategies how to avoid such eventual possible unintended or unexpected indirect legal effects of MOUs when drafting such instruments and when dealing with them subsequent to their respective ‘adoption’.

CY - Berlin ER - TY - BOOK A1 - Barkowsky, Matthias A1 - Giese, Holger T1 - Modular and incremental global model management with extended generalized discrimination networks T1 - Modulares und inkrementelles Globales Modellmanagement mit erweiterten Generalized Discrimination Networks N2 - Complex projects developed under the model-driven engineering paradigm nowadays often involve several interrelated models, which are automatically processed via a multitude of model operations. Modular and incremental construction and execution of such networks of models and model operations are required to accommodate efficient development with potentially large-scale models. The underlying problem is also called Global Model Management. In this report, we propose an approach to modular and incremental Global Model Management via an extension to the existing technique of Generalized Discrimination Networks (GDNs). In addition to further generalizing the notion of query operations employed in GDNs, we adapt the previously query-only mechanism to operations with side effects to integrate model transformation and model synchronization. We provide incremental algorithms for the execution of the resulting extended Generalized Discrimination Networks (eGDNs), as well as a prototypical implementation for a number of example eGDN operations. Based on this prototypical implementation, we experiment with an application scenario from the software development domain to empirically evaluate our approach with respect to scalability and conceptually demonstrate its applicability in a typical scenario. Initial results confirm that the presented approach can indeed be employed to realize efficient Global Model Management in the considered scenario. N2 - Komplexe Projekte, die unter dem Paradigma der modellgetriebenen Entwicklung entwickelt werden, nutzen heutzutage oft mehrere miteinander in Beziehung stehende Modelle, die durch eine Vielzahl von Modelloperationen automatiscsh verarbeitet werden. Die modulare und inkrementelle Konstruktion und Ausführung solcher Netzwerke von Modelloperationen ist eine Voraussetzung für effiziente Entwicklung mit potenziell sehr großen Modellen. Das zugrunde liegende Forschungsproblem heißt auch Globales Modellmanagement. In diesem Bericht schlagen wir einen Ansatz für modulares und inkrementelles Globales Modellmanagement vor, der auf einer Erweiterung der existierenden Technik der Generalized Discrimination Networks (GDNs) basiert. Neben einer weiteren Verallgemeinerung des Konzepts der Anfrageoperationen in GDNs erweitern wir den zuvor rein lesenden Mechanismus auf Operationen mit Seiteneffekten, um Modelltransformationen und Modellsynchronisationen zu integrieren. Wir präsentieren inkrementelle Algorithmen für die Ausführung der resultierenden erweiterten GDNs (eGDNs) sowie eine prototypische Implementierung von Beispieloperationen für eGDNs. Mithilfe dieser prototypischen Implementierung evaluieren wir unsere Lösung hinsichtlich ihrer Skalierbarkeit in einem Anwendungsszenario aus dem Bereich der Softwareentwicklung. Außerdem demonstrieren wir die Anwendbarkeit der entwickelten Technik konzeptionell anhand eines typischen Anwendugsszenario. Unsere ersten Ergebnisse bestätigen, dass die Lösung genutzt werden kann, um effizientes Globales Modellmanagement im betrachteten Szenario zu realisieren.

They were asked to list all their publications in the field of Celtic Studies, so as to allow to carry out a survey of their research activities during this period. While most scholars kindly obliged by returning their lists, there were notable exceptions who never answered the query. Regretably, the present bibliography therefore contains important gaps, which, however, may be quite telling as far as the research situation in Germany was concerned during that period.

N2 - The great Old English epic 'Beowulf' has been dated to practically every century between the 6th and the 11th century, depending on the criteria of dating adopted and the approaches advocated by the respective scholars. As the text successfully avoids to provide definite cues or evidence for a definitive date, these scholarly attempts reveal more about the respective scholars' research interests than offering uncontroversial dates. The point of dating 'Beowulf' then seems to provide scholars with the opportunity to anchor their own personal understanding of the poem within the century of their own personal predilection.

N2 - Periphrastic English constructions involving the verbs BE/HAVE + a nominalised verb form expressing [+imperfectivity] and [+perfectivity] have close analogues in the Insular Celtic languages, where Celtic analogues of the English verb BE + a prepositional construction marker + Verbal Noun are used. The two constructions in English and teh Celtic languages are not identical and cannot be so, because the Celtic languages do not feature present and past participles and English has no verbal nouns. But the two types of the periphrastic mode of expressing aspect are close enough to suggest either a shift scenario, a borrowing scenario and/or an areal spread by diffusion over a long period of time. Since Old English did not mark aspect, neither morphologically nor syntactically, but Old Welsh and Old Irish already did so syntactically, it is suggested here that a unilateral transfer process was involved here, which proceeded from the Celtic languages to the English language. Aspectual transfer is even more pronounced in the so-called 'Celtic Englishes,' where in addition to the periphrastic marking of [+ imperfectivity] and [+perfectivity] the marking of [+habituality] is a grammaticalised feature and is periphrastically expressed.

T1 - European Versification : the Effect of Literacy N2 - A report of Mikhail Gasparov's 1989 book on the 'History of European Versification' is the starting point of the discussion in this article of the types of versification found in the Insular Celtic literatures from their first documenation in the early middle ages to the present day, as Gasparov's survey does not cover these poetries. It is claimed here that their metrical constraints were pre-literate and first and foremost geared at aural reception. The introduction of writing led to an increase in metrical sophistication which, while still basically oral, because of the process of "prelecting" (i.e. reading out aloud to illiterate or semi-literate audiences), required a very careful appreciation of their metrical skills. Contact with English and French syllabic poetry in the later middle ages and particularly in the modern period produced so-called "free verse" poetry. The word "free" in this particular context meant that the rather loose metrical constraints of these majority literatures in no way compared with the extraordinarily high metrical sophistication of the native oral derived or "bardic" poetry.

It examines reforms of the external relationships between local governments and private service providers, which were aimed at transforming the organizational macro-setting of local service provision, the task portfolio and functional profile of local governments. The chapter then moves to scrutinizing internal managerial reforms concerned with the modernization of organization and processes and the improvement of management capacities inside local administrations meant to strengthen performance, output- and consumer-orientation in local service delivery. The country sample includes the United Kingdom (England), Sweden, and Germany that represent three distinct types of administrative culture and local government in Europe.

But when and how do such adaptation processes give way to a more profound transformation, if not a crisis of international law? To address the question of how attacks on the international legal order are changing the value orientation of international law, this book brings together scholars of international law and international relations. By combining theoretical and methodological analyses with individual case studies, this book offers readers conceptualizations and tools to systematically examine value change and explore the drivers and mechanisms of these processes. These case studies scrutinize value change in the foundational norms of the post-1945 order and in norms representing the rise of the international legal order post-1990. They cover diverse issues: the prohibition of torture, the protection of women’s rights, the prohibition of the use of force, the non-proliferation of nuclear weapons, sustainability norms, and accountability for core international crimes. The challenges to each norm, the reactions by norm defenders, and the fate of each norm are also studied. Combined, the analyses show that while a few norms have remained surprisingly robust, several are changing, either in substance or in legal or social validity. The book concludes by integrating the conceptual and empirical insights from this interdisciplinary exchange to assess and explain the ambiguous nature of value change in international law beyond the extremes of mere progress or decline.

We focus on two analytical key dimensions: a) the provider of the evaluation and b) the subject of the evaluation. Four major types of evaluation are distinguished: (1) external institutional evaluation, (2) internal institutional evaluation, (3) external evaluation of administrative action/results, (4) internal evaluation of administrative action/results. Type 1 and 2 refer to evaluation of administrative structures and processes as the subject of administrative reform. Type 3 and 4 represent different versions of evaluation in public administration, because the subject is administrative action and its outputs. The chapter highlights salient approaches and organizational settings of evaluation and provides insights into the institutionalization of an evaluation function in public administration.

Based on the literature sample of 4,056 articles published between 1960 and 2020 by 3,600 authors in 783 journals and their 175,163 references, we identify the most productive and most cited journals, the most cited authors, and the 25 most cited articles. Our science mapping reveals the agency theory, definitions, entrepreneurship, internationalization, ownership, resources, socioemotional wealth, and succession as the predominant research themes in family firm research. Whereas entrepreneurship explicitly appears in one of the clusters, innovation does not yet. Based on our findings, we propose a research framework and point to several research gaps to be addressed by future research.

Some PSOs already successfully deploy conversational agents (CAs) to communicate with citizens and support digital service delivery. In this paper, we used design science research (DSR) to examine how CAs could be designed to assist PSOs in fighting false information online. We conducted a workshop with the municipality of Kristiansand, Norway to define objectives that a CA would have to meet for addressing the identified false information challenges. A prototypical CA was developed and evaluated in two iterations with the municipality and students from Norway. This research-in-progress paper presents findings and next steps of the DSR process. This research contributes to advancing the digital transformation of the public sector in combating false information problems.

To shed light on the consequences of videoconferencing at work, this study takes a granular look at the implications of the self-view feature for meeting outcomes. Building on self-awareness research and self-regulation theory, we argue that by heightening the state of self-awareness, self-view engagement depletes participants’ mental resources and thereby can undermine online meeting outcomes. Evaluation of our theoretical model on a sample of 179 employees reveals a nuanced picture. Self-view engagement while speaking and while listening is positively associated with self-awareness, which, in turn, is negatively associated with satisfaction with meeting process, perceived productivity, and meeting enjoyment. The criticality of the communication role is put forward: looking at self while listening to other attendees has a negative direct and indirect effect on meeting outcomes; however, looking at self while speaking produces equivocal effects.

The chapter focuses on the European Commission and its evolving role in promoting decarbonisation efforts in its Member States, paying particular attention to its role in financing investments in low-carbon assets. It considers both the direct effects of green stimulus policies on decarbonisation in the EU and how these actions have shaped the capacities of the Commission as an actor in the field of climate and energy policy. The analysis reveals a significant expansion of the Commission’s role compared to the period following the financial crisis. EU-level measures have provided incentives for Member States to direct large volumes of financing towards investments in climate-friendly assets. Nevertheless, the ultimate impact will largely be shaped by implementation at the national level.

They discern a mixed picture of an international order between metamorphosis—that is, a more fundamental transformation—of international law, norm change, turbulences, and robustness. They explain drivers of change and highlight factors such as national interests during the war on terror, changing long-term foreign policy beliefs, and the rise in populism and autocracy, before discussing the most common strategies the actors involved use. Other relevant factors include changes in the political environment, such as shocks and power shifts or the ambiguous role of fragmentation. Moreover, they identify factors that make legal norms robust, including the vital role of norm defenders and legal and institutional structures as stabilizing elements. Krieger and Liese conclude by cautioning that if the attacks on the international order continue at the current frequency and magnitude, a metamorphosis of international law will likely be unstoppable.

As this paper argues, this is partly due to a concept of terrorism utilized by policymakers, intelligence agents, and police investigators that is based on experience of international terrorism perpetrated by leftists or jihadists as opposed to domestic extreme-right violence. This was one reason why investigators failed to identify the crimes committed by the National Socialist Underground (NSU) in Germany (2000–2011) as extreme-right terrorism, for example. While scholarly debate focused on the Red Army Faction and Al Qaeda, terrorist tendencies among those perpetrating racist and extreme-right violence tended to be disregarded. Influential researchers in the field of “extremism” denied that terrorist acts were committed by right-wingers. By mapping the specifics regarding the strategic use of violence, target selection, addressing of different audiences etc., this paper proposes a more accurate definition of extreme-right terrorism. In comparing it to other forms of terrorism, extreme-right terrorism is distinguished by its specific framework of ideologies and practices, with the underlying idea of an essential inequality that is compensated for through the affirmation of violence. It can be differentiated from other forms of extreme-right violence based on its use of strategic, premeditated and planned attacks against targets of a symbolic nature.

While the impact of digitalization on education was already a point of serious deliberation, the COVID-19 pandemic has expedited ongoing transitions. With 90% of the world’s student population having been impacted by national lockdowns—online learning has gone from being a luxury to a necessity, in a context where around 3.6 billion people are offline. As the impacts of the 4IR unfold alongside the current crisis, it is not enough for future policy pathways to prioritize educational attainment in the traditional sense; it is essential to reimagine education itself as well as its delivery entirely. Future policy narratives will need to evaluate the very process of learning and identify the ways in which technology can help reduce existing disparities and enhance digital access, literacy and fluency in a scalable manner. In this context, this chapter analyses the status quo of online learning in India and Germany. Drawing on the experiences of these two economies with distinct trajectories of digitalization, the chapter explores how new technologies intersect with traditional education and local sociocultural conditions. Further, the limitations and opportunities presented by dominant ed-tech models is critically analyzed against the ongoing COVID-19 pandemic.

Due to the great diversity of digital platform concepts, clear definitions are still required. Furthermore, DPs are subject to dynamic changes from internal and external factors, which pose challenges for digital platform operators, developers and customers. Which current digital platform research directions should be taken to address these challenges remains open so far. The following paper aims to contribute to this by outlining a systematic literature review (SLR) on digital platform concepts in the context of the Industrial Internet of Things (IIoT) for manufacturing companies and provides a basis for (1) a selection of definitions of current digital platform and ecosystem concepts and (2) a selection of current digital platform research directions. These directions are diverted into (a) occurrence of digital platforms, (b) emergence of digital platforms, (c) evaluation of digital platforms, (d) development of digital platforms, and (e) selection of digital platforms.

Thus, Law Enforcement Agencies (LEA) are deployed in many countries and organisations to enhance the preventive and reactive capabilities against cyberabuse. However, their tasks are getting more complex by the increasing amount and varying quality of information disseminated into public channels. Adopting the perspectives of Crisis Informatics and safety-critical Human-Computer Interaction (HCI) and based on both a narrative literature review and group discussions, this paper first outlines the research agenda of the CYLENCE project, which seeks to design strategies and tools for cross-media reporting, detection, and treatment of cyberbullying and hatespeech in investigative and law enforcement agencies. Second, it identifies and elaborates seven research challenges with regard to the monitoring, analysis and communication of cyberabuse in LEAs, which serve as a starting point for in-depth research within the project.

Drawing on Foucault’s lectures on biopolitics and Brown’s current analysis of neoliberalism, it lays out a sociological explanation that treats the idea of homo economicus as a structuring element of our society and outlines the threat this poses to the liberal democratic order. The second part of the contribution outlines – through immanent critique – an ideology-critical analytical competence that uses key problems to illuminate socially critical perspectives on social reality. The objective is to challenge some of the foundations of social order (Salomon, D. Kritische politische Bildung. Ein Versuch. In B. Widmaier & Overwien, B.

In this paper we proceed from the assumption that the role of politics, the constellation of political actors and arenas vary according to the scope and objectives of administrative reforms. Depending on whether they refer to changes between organizational units/levels/sectors ('external institutional policy') or to an internal reorganization ('internal institutional policy'), different actor strategies, patterns of conflict and power constellations can be expected. As external administrative reforms are aimed at changing functional and/or territorial jurisdictions and thus always involve external actors, larger resistance, heavier political conflicts and generally more politicization are likely to occur than in the case of internal administrative reforms. Yet, for internal reforms, too, actor coalitions which support or block institutional changes, promotors, leaders, and moderators have revealed to shape processes and outcomes. Against this background, this chapter examines the influence of politics on various types of administrative reforms making a distinction between external and internal institutional policies. We analyse the role of politico-administrative actors, their strategies and influence on the formulation, trajectories and outcomes of administrative reforms. Our major focus will be on reforms in the multi-level system on the one hand and on (Post-) NPM reforms on the other as two major international trends. Drawing on reform experiences in different European countries, the chapter will reveal to what extent actors' interests and influences have triggered and shaped administrative reforms and which difference these have made for the reform outcome.

T2 - CESifo Working Paper N2 - Labor unions’ greatest potential for political influence likely arises from their direct connection to millions of individuals at the workplace. There, they may change the ideological positions of both unionizing workers and their non-unionizing management. In this paper, we analyze the workplace-level impact of unionization on workers’ and managers’ political campaign contributions over the 1980-2016 period in the United States. To do so, we link establishment-level union election data with transaction-level campaign contributions to federal and local candidates. In a difference-in-differences design that we validate with regression discontinuity tests and a novel instrumental variables approach, we find that unionization leads to a leftward shift of campaign contributions. Unionization increases the support for Democrats relative to Republicans not only among workers but also among managers, which speaks against an increase in political cleavages between the two groups. We provide evidence that our results are not driven by compositional changes of the workforce and are weaker in states with Right-to-Work laws where unions can invest fewer resources in political activities.

For governments that run whole countries, this means asking all citizens for their views to consider their situations and needs. Organizations such as Africa's Voices Foundation, who want to facilitate communication between decision-makers and citizens of a country, have difficulty mediating between these groups. To enable understanding, statements need to be summarized and visualized. Accomplishing these goals in a way that does justice to the citizens' voices and situations proves challenging. Standard charts do not help this cause as they fail to create empathy for the people behind their graphical abstractions. Furthermore, these charts do not create trust in the data they are representing as there is no way to see or navigate back to the underlying code and the original data. To fulfill these functions, visualizations would highly benefit from interactions to explore the displayed data, which standard charts often only limitedly provide. To help improve the understanding of people's voices, we developed and categorized 80 ideas for new visualizations, new interactions, and better connections between different charts, which we present in this report. From those ideas, we implemented 10 prototypes and two systems that integrate different visualizations. We show that this integration allows consistent appearance and behavior of visualizations. The visualizations all share the same main concept: representing each individual with a single dot. To realize this idea, we discuss technologies that efficiently allow the rendering of a large number of these dots. With these visualizations, direct interactions with representations of individuals are achievable by clicking on them or by dragging a selection around them. This direct interaction is only possible with a bidirectional connection from the visualization to the data it displays. We discuss different strategies for bidirectional mappings and the trade-offs involved. Having unified behavior across visualizations enhances exploration. For our prototypes, that includes grouping, filtering, highlighting, and coloring of dots. Our prototyping work was enabled by the development environment Lively4. We explain which parts of Lively4 facilitated our prototyping process. Finally, we evaluate our approach to domain problems and our developed visualization concepts. Our work provides inspiration and a starting point for visualization development in this domain. Our visualizations can improve communication between citizens and their government and motivate empathetic decisions. Our approach, combining low-level entities to create visualizations, provides value to an explorative and empathetic workflow. We show that the design space for visualizing this kind of data has a lot of potential and that it is possible to combine qualitative and quantitative approaches to data analysis. N2 - Der noble Weg, Entscheidungen, die viele Menschen betreffen, zu begründen, besteht darin, diese Menschen nach ihrer Meinung zu fragen. Für Regierungen, die ganze Länder führen, bedeutet dies, alle Bürger nach ihrer Meinung zu fragen, um ihre Situationen und Bedürfnisse zu berücksichtigen. Organisationen wie die Africa's Voices Foundation, die die Kommunikation zwischen Entscheidungsträgern und Bürgern eines Landes erleichtern wollen, haben Schwierigkeiten, zwischen diesen Gruppen zu vermitteln. Um Verständnis zu ermöglichen, müssen die Aussagen zusammengefasst und visualisiert werden. Diese Ziele auf eine Weise zu erreichen, die den Stimmen und Situationen der Bürgerinnen und Bürger gerecht wird, erweist sich als Herausforderung. Standardgrafiken helfen dabei nicht weiter, da es ihnen nicht gelingt, Empathie für die Menschen hinter ihren grafischen Abstraktionen zu schaffen. Darüber hinaus schaffen diese Diagramme kein Vertrauen in die Daten, die sie darstellen, da es keine Möglichkeit gibt, den verwendeten Code und die Originaldaten zu sehen oder zu ihnen zurück zu navigieren. Um diese Funktionen zu erfüllen, würden Visualisierungen sehr von Interaktionen zur Erkundung der angezeigten Daten profitieren, die Standardgrafiken oft nur begrenzt bieten. Um das Verständnis der Stimmen der Menschen zu verbessern, haben wir 80 Ideen für neue Visualisierungen, neue Interaktionen und bessere Verbindungen zwischen verschiedenen Diagrammen entwickelt und kategorisiert, die wir in diesem Bericht vorstellen. Aus diesen Ideen haben wir 10 Prototypen und zwei Systeme implementiert, die verschiedene Visualisierungen integrieren. Wir zeigen, dass diese Integration ein einheitliches Erscheinungsbild und Verhalten der Visualisierungen ermöglicht. Die Visualisierungen haben alle das gleiche Grundkonzept: Jedes Individuum wird durch einen einzigen Punkt dargestellt. Um diese Idee zu verwirklichen, diskutieren wir Technologien, die die effiziente Darstellung einer großen Anzahl dieser Punkte ermöglichen. Mit diesen Visualisierungen sind direkte Interaktionen mit Darstellungen von Individuen möglich, indem man auf sie klickt oder eine Auswahl um sie herumzieht. Diese direkte Interaktion ist nur mit einer bidirektionalen Verbindung von der Visualisierung zu den angezeigten Daten möglich. Wir diskutieren verschiedene Strategien für bidirektionale Mappings und die damit verbundenen Kompromisse. Ein einheitliches Verhalten über Visualisierungen hinweg verbessert die Exploration. Für unsere Prototypen umfasst dies Gruppierung, Filterung, Hervorhebung und Einfärbung von Punkten. Unsere Arbeit an den Prototypen wurde durch die Entwicklungsumgebung Lively4 ermöglicht. Wir erklären, welche Teile von Lively4 unseren Prototyping-Prozess erleichtert haben. Schließlich bewerten wir unsere Herangehensweise an Domänenprobleme und die von uns entwickelten Visualisierungskonzepte. Unsere Arbeit liefert Inspiration und einen Ausgangspunkt für die Entwicklung von Visualisierungen in diesem Bereich. Unsere Visualisierungen können die Kommunikation zwischen Bürgern und ihrer Regierung verbessern und einfühlsame Entscheidungen motivieren. Unser Ansatz, bei dem wir niedrigstufige Entitäten zur Erstellung von Visualisierungen kombinieren, bietet einen wertvollen Ansatz für einen explorativen und einfühlsamen Arbeitsablauf. Wir zeigen, dass der Designraum für die Visualisierung dieser Art von Daten ein großes Potenzial hat und dass es möglich ist, qualitative und quantitative Ansätze zur Datenanalyse zu kombinieren.

Not just the act of crochet itself is manual but also the process of creating instructions for new crochet patterns, which is barely supported by domain specific digital solutions. This leads to unstructured and often also ambiguous and erroneous pattern instructions. In this report, we propose a concept to digitally represent crochet patterns. This format incorporates crochet techniques which allows domain specific support for crochet pattern designers during the pattern creation and instruction writing process. As contributions, we present a thorough domain analysis, the concept of a graph structure used as domain specific language to specify crochet patterns and a prototype of a projectional editor using the graph as representation format of patterns and a diagramming system to visualize them in 2D and 3D. By analyzing the domain, we learned about crochet techniques and pain points of designers in their pattern creation workflow. These insights are the basis on which we defined the pattern representation. In order to evaluate our concept, we built a prototype by which the feasibility of the concept is shown and we tested the software with professional crochet designers who approved of the concept. N2 - Häkeln ist eine weltweit verbreitete Handarbeitskunst. Obwohl andere Techniken, wie stricken und weben über die Zeit maschinelle Unterstützung erhalten haben, ist Häkeln noch heute ein komplett manueller Vorgang. Nicht nur das Häkeln an sich, sondern auch der Prozess zur Anleitungserstellung von neuen Häkeldesigns ist kaum unterstützt mit digitalen Lösungen. In dieser Arbeit stellen wir ein Konzept vor, das Häkelanleitungen digital repräsentiert. Das entwickelte Format integriert Häkeltechniken, wodurch wir den Prozess des Anleitungschreibens für Designer spezifisch für die Häkeldomäne unterstützen können. Als Beiträge analysieren wir umfassend die Häkeldomäne, entwickeln ein Konzept zur Repräsentation von Häkelanleitungen basierend auf einer Graphenstruktur als domänenspezifische Sprache und implementieren einen projektionalen Editor, der auf der besagten Graphenstruktur aufbaut und weiterhin die erstellten Anleitungen als schematische Darstellung in 2D und 3D visualisiert. Durch die Analyse der Domäne lernen wir Häkeltechniken und Schwachstellen beim Ablauf des Anleitungserstellens kennen. Basierend auf diesen Erkenntnissen entwickeln wir das digitale Format, um Anleitungen zu repräsentieren. Für die Evaluierung unseres Konzepts, haben wir einen Prototypen implementiert, der die Machbarkeit demonstriert. Zudem haben wir die Software von professionellen Häkeldesignern testen lassen, die unsere Herangehensweise gutheißen.

Those fast changes require immediate feedback. Also, it should be possible to parse the developed languages quickly to handle extensive sets of code. Parsing expression grammars provides an easy to understand method for language definitions. Packrat parsing is a method to parse grammars of this kind, but this method is unable to handle left-recursion properly. Existing solutions either partially rewrite left-recursive rules and partly forbid them, or use complex extensions to packrat parsing that are hard to understand and cost-intensive. We investigated methods to make parsing as fast as possible, using easy to follow algorithms while not losing the ability to make fast changes to grammars. We focused our efforts on two approaches. One is to start from an existing technique for limited left-recursion rewriting and enhance it to work for general left-recursive grammars. The second approach is to design a grammar compilation process to find left-recursion before parsing, and in this way, reduce computational costs wherever possible and generate ready to use parser classes. Rewriting parsing expression grammars is a task that, if done in a general way, unveils a large number of cases such that any rewriting algorithm surpasses the complexity of other left-recursive parsing algorithms. Lookahead operators introduce this complexity. However, most languages have only little portions that are left-recursive and in virtually all cases, have no indirect or hidden left-recursion. This means that the distinction of left-recursive parts of grammars from components that are non-left-recursive holds great improvement potential for existing parsers. In this report, we list all the required steps for grammar rewriting to handle left-recursion, including grammar analysis, grammar rewriting itself, and syntax tree restructuring. Also, we describe the implementation of a parsing expression grammar framework in Squeak/Smalltalk and the possible interactions with the already existing parser Ohm/S. We quantitatively benchmarked this framework directing our focus on parsing time and the ability to use it in a live programming context. Compared with Ohm, we achieved massive parsing time improvements while preserving the ability to use our parser it as a live programming tool. The work is essential because, for one, we outlined the difficulties and complexity that come with grammar rewriting. Also, we removed the existing limitations that came with left-recursion by eliminating them before parsing.

The rule-based formalism of probabilistic timed graph transformation systems is a suitable choice when the models representing states of the system can be understood as graphs and timed and probabilistic behavior is important. However, model checking PTGTSs is limited to systems with rather small state spaces. We present an approach for the analysis of large scale systems modeled as probabilistic timed graph transformation systems by systematically decomposing their state spaces into manageable fragments. To obtain qualitative and quantitative analysis results for a large scale system, we verify that results obtained for its fragments serve as overapproximations for the corresponding results of the large scale system. Hence, our approach allows for the detection of violations of qualitative and quantitative safety properties for the large scale system under analysis. We consider a running example in which we model shuttles driving on tracks of a large scale topology and for which we verify that shuttles never collide and are unlikely to execute emergency brakes. In our evaluation, we apply an implementation of our approach to the running example. N2 - Die Analyse von Verhaltensmodellen ist für cyber-physikalische Systeme von hoher Bedeutung, da die Systeme häufig komplexes Verhalten umfassen, das z.B. parallele Komponenten mit gegenseitigem Ausschluss oder probabilistischen Fehlern bei Bedarf umfasst. Der regelbasierte Formalismus probabilistischer zeitgesteuerter Graphtransformationssysteme ist eine geeignete Wahl, wenn die Modelle, die Zustände des Systems darstellen, als Graphen verstanden werden können und zeitgesteuertes und probabilistisches Verhalten wichtig ist. Modelchecking von PTGTSs ist jedoch auf Systeme mit relativ kleinen Zustandsräumen beschränkt. Wir präsentieren einen Ansatz zur Analyse von Großsystemen, die als probabilistische zeitgesteuerte Graphtransformationssysteme modelliert wurden, indem ihre Zustandsräume systematisch in überschaubare Fragmente zerlegt werden. Um qualitative und quantitative Analyseergebnisse für ein Großsystem zu erhalten, überprüfen wir, ob die für seine Fragmente erhaltenen Ergebnisse als Überannäherungen für die entsprechenden Ergebnisse des Großsystems dienen. Unser Ansatz ermöglicht es daher, Verstöße gegen qualitative und quantitative Sicherheitseigenschaften für das untersuchte Großsystem zu erkennen. Wir betrachten ein Beispiel, in dem wir Shuttles modellieren, die auf Gleisen einer großen Topologie fahren, und für die wir überprüfen, dass Shuttles niemals kollidieren und wahrscheinlich keine Notbremsungen ausführen. In unserer Auswertung wenden wir eine Implementierung unseres Ansatzes auf das Beispiel an.

That juridical blockchain recorder has been realized as distributed ledger on board the advanced TrainLab (ICE-TD 605 017) of Deutsche Bahn. For the project, a consortium consisting of DB Systel, Siemens, Siemens Mobility, the Hasso Plattner Institute for Digital Engineering, Technische Universität Braunschweig, TÜV Rheinland InterTraffic, and Spherity has been formed. These partners not only concentrated competencies in railway operation, computer science, regulation, and approval, but also combined experiences from industry, research from academia, and enthusiasm from startups. Distributed ledger technologies (DLTs) define distributed databases and express a digital protocol for transactions between business partners without the need for a trusted intermediary. The implementation of a blockchain with real-time requirements for the local network of a railway system (e.g., interlocking or train) allows to log data in the distributed system verifiably in real-time. For this, railway-specific assumptions can be leveraged to make modifications to standard blockchains protocols. EULYNX and OCORA (Open CCS On-board Reference Architecture) are parts of a future European reference architecture for control command and signalling (CCS, Reference CCS Architecture – RCA). Both architectural concepts outline heterogeneous IT systems with components from multiple manufacturers. Such systems introduce novel challenges for the approved and safety-relevant CCS of railways which were considered neither for road-side nor for on-board systems so far. Logging implementations, such as the common juridical recorder on vehicles, can no longer be realized as a central component of a single manufacturer. All centralized approaches are in question. The research project RailChain is funded by the mFUND program and gives practical evidence that distributed consensus protocols are a proper means to immutably (for legal purposes) store state information of many system components from multiple manufacturers. The results of RailChain have been published, prototypically implemented, and experimentally evaluated in large-scale field tests on the advanced TrainLab. At the same time, the project showed how RailChain can be integrated into the road-side and on-board architecture given by OCORA and EULYNX. Logged data can now be analysed sooner and also their trustworthiness is being increased. This enables, e.g., auditable predictive maintenance, because it is ensured that data is authentic and unmodified at any point in time. N2 - Das Projekt RailChain hat einen verteilten Juridical Recorder entworfen, implementiert und experimentell evaluiert, der auf einem echtzeitfähigen verteilten Konsensprotokoll basiert. Dieser Juridical Blockchain Recorder wurde als distributed ledger an Bord des advanced TrainLabs der Deutschen Bahn (ICE-TD 605 017) umgesetzt. Für das Projekt hat sich ein Konsortium aus DB Systel, Siemens, Siemens Mobility, dem Hasso-Plattner-Institut für Digital Engineering, der Technischen Universität Braunschweig, sowie TÜV Rheinland InterTraffic und Spherity formiert und dabei Kompetenzen aus den Bereichen Bahnbetrieb, Informatik und Zulassungswesen gebündelt. Die Partner kombinieren Erfahrungen aus der Industrie und die akademische Forschung mit der Aufbruchstimmung aus dem Start-Up-Umfeld. Distributed-Ledger-Technologien (DLTs) definieren verteilte Datenbanken und stellen ein digitales Protokoll für Transaktionen zwischen Geschäftspartnern dar, ohne dass ein Mittelsmann beteiligt sein müsste. Die Implementierung einer Blockchain mit Echtzeitanforderungen für das lokale Netzwerk einer Eisenbahnanlage (z. B. Stellwerk oder Zug) erlaubt es, die im verteilten System entstehenden Daten nachweislich in Echtzeit zu protokollieren. Dabei können eisenbahnspezifische Randbedingungen ausgenutzt werden, um Standard-Blockchain-Protokolle anzupassen. EULYNX und OCORA (Open CCS On-board Reference Architecture) sind Bestandteile einer zukünftigen europäischen Referenzarchitektur für das Leit- und Sicherungssystem (Reference CCS Architecture – RCA, Control Command and Signalling – CCS). Beide Architekturkonzepte skizzieren herstellerübergreifende, komponentenbasierende heterogene IT-Systeme. Solche Systeme bergen neue Herausforderungen, die bislang im Kontext der zugelassenen, sicherheitsrelevanten Leit- und Sicherungstechnik der Bahn weder strecken- noch fahrzeugseitig adressiert werden mussten. Logbuch-Implementierungen, wie der gängige Juridical Recorder auf Fahrzeugen, können nun nicht mehr als zentrale Systemkomponente eines einzelnen Herstellers umgesetzt werden. Alle zentralisierten Lösungsansätze sind in Frage gestellt. Das mFUND-geförderte Forschungsprojekt erbringt den praktischen Nachweis, dass Zustandsinformationen über eine Vielzahl von Systemkomponenten herstellerübergreifend und gerichtsfest mittels verteilten Konsensprotokollen gespeichert werden können. Ergebnisse von RailChain wurden publiziert, prototypisch implementiert und in großen Feldtests auf dem advanced TrainLab experimentell evaluiert. Gleichzeitig wurde aufgezeigt, wie sich RailChain in den mit OCORA und EULYNX vorgegebenen fahrzeug- und streckenseitigen Architekturentwurf integrieren lässt. Daten können dadurch zeitnaher ausgewertet werden und gleichzeitig wird ihre Vertrauenswürdigkeit erhöht. Dies ermöglicht u. a. nachvollziehbare zustandsorientierte Wartung, denn es kann jederzeit sichergestellt werden, dass die Daten authentisch sind und auch nicht verändert wurden.
