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 - THES A1 - Sójka, Pia T1 - Writing travel, writing life T1 - Reisen schreiben Leben T1 - Écriture, le voyage ou la vie BT - Ars Vivendi and the travelling narrations of Ella Maillart, Annemarie Schwarzenbach and Nicolas Bouvier BT - Ars Vivendi und die reisenden Erzählungen von Ella Maillart, Annemarie Schwarzenbach und Nicolas Bouvier BT - Ars Vivendi et les narrations itinérantes d'Ella Maillart, Annemarie Schwarzenbach et Nicolas Bouvier N2 - The book compares the texts of three Swiss authors: Ella Maillart, Annemarie Schwarzenbach and Nicolas Bouvier. 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. N2 - Das Buch vergleicht die Texte von drei Schweizer Autoren: Ella Maillart, Annemarie Schwarzenbach und Nicolas Bouvier. Im Mittelpunkt steht die Reise von Genève nach Kabul, die Ella Maillart gemeinsam mit Annemarie Schwarzenbach 1939/1940 und Nicolas Bouvier 1953/1954 mit dem Künstler Thierry Vernet unternahmen. 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. N2 - Le livre compare les textes de trois auteurs suisses : Ella Maillart, Annemarie Schwarzenbach et Nicolas Bouvier. L'accent est mis sur le voyage de Genève à Kaboul qu'Ella Maillart et Annemarie Schwarzenbach ont effectué ensemble en 1939/1940 et Nicolas Bouvier 1953/1954 avec l'artiste Thierry Vernet. La comparaison montre le lien fort entre le voyage et la vie et entre l'ars vivendi et la littérature de voyage. Ce livre donne également un aperçu et organise les nombreux termes, genres et catégories qui existent déjà pour décrire les différents textes de voyage et propose le nouveau terme narration itinérante „travelling literature“. La narration itinérante examine le texte dans une perspective narratologique qui distingue l'auteur, le narrateur et le protagoniste au sein de la narration. Au cours de l'examen, dix motifs ont été trouvés pour caractériser le récit de voyage : La culture, la traversée des frontières, la liberté, le temps et l'espace, l'esthétique des paysages, l'écriture et la lecture, le soi et l'autre, la maison, la religion et la spiritualité ainsi que le voyage. L'importance de chaque motif individuel ne s'applique pas seulement aux années 1930 ou 1950, mais transmet également des conclusions importantes pour le vivre ensemble aujourd'hui et à l'avenir.

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.

Numerous studies have investigated consequences of workplace friendships and found positive outcomes, such as increased employee job satisfaction or organizational performance, as well as negative outcomes, such as decreased knowledge-sharing between different friendship cliques. Other studies have examined what shapes workplace friendships, focusing on determinants such as personality or the spatial composition of organizations. Finally, an increasing number of studies focus on multiplex workplace friendships, where employees who are friends are also linked by a specific work-focused relationship. In this chapter, we first take stock of the literature on workplace friendships by providing an overview of their antecedents and consequences at the individual, the group, and the organizational level, and review the smaller body of research on multiplex workplace friendships. Second, we critically discuss practical implications of workplace friendships, focusing on their relevance to three current challenges for employees and organizations: the increase in virtual work, social inequalities in organizations, and the increased overlap of professional and private life. Finally, we provide recommendations for organizations on how to address these challenges and effectively manage workplace friendships.

C. T1 - What's the Point of Dating Beowulf? 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.

BT - a systematic literature review and ethical-legal discussion T2 - Wirtschaftsinformatik 2023 Proceedings N2 - Disinformation campaigns spread rapidly through social media and can cause serious harm, especially in crisis situations, ranging from confusion about how to act to a loss of trust in government institutions. Therefore, the prevention of digital disinformation campaigns represents an important research topic. However, previous research in the field of information systems focused on the technical possibilities to detect and combat disinformation, while ethical and legal perspectives have been neglected so far. In this article, we synthesize previous information systems literature on disinformation prevention measures and discuss these measures from an ethical and legal perspective. We conclude by proposing questions for future research on the prevention of disinformation campaigns from an IS, ethical, and legal perspective. In doing so, we contribute to a balanced discussion on the prevention of digital disinformation campaigns that equally considers technical, ethical, and legal issues, and encourage increased interdisciplinary collaboration in future research.

Comparing adolescents who responded to our survey shortly before the start of the war with those who responded shortly after the conflict began and applying difference-in-differences (DiD) models over time, we find a significant decline in the outcome after the war started. These findings provide new evidence on how armed conflicts influence social trust and well-being among young people in a country not directly involved in the war.

Especially, Instagram is known for its focus on beauty, fitness, fashion, and dietary topics. Although a large body of research reports negative weight-related outcomes of SNS usage (e.g., body dissatisfaction, body image concerns), studies examining how SNS usage relates to these outcomes are scarce. Based on the visual normalization theory, we argue that SNS content facilitates normalization of so-called thin- and fit-ideals, thereby leading to biased perceptions of the average body weight in society. Therefore, this study tests whether Instagram use is associated with perceiving that the average person weighs less. Responses of 181 survey participants confirm that Instagram use is negatively related to average weight perception of both women and men. These findings contribute to the growing body of research on how SNS use relates to negative weight-related outcomes.

Since knowledge can be both tacit and explicit, its transfer from the individual to the organizational knowledge base poses a challenge in organizations. This challenge increases when the fluctuation of knowledge carriers is exceptionally high. Especially in large projects in which external consultants are involved, there is a risk that critical, company-relevant knowledge generated in the project will leave the company with the external knowledge carrier and thus be lost. In this paper, we show the advantages of an early warning system for knowledge management to avoid this loss. In particular, the potential of visual analytics in the context of knowledge management systems is presented and discussed. We present a project for the development of a business-critical software system and discuss the first implementations and results.

ED - Guérin, Charles T1 - Varro and the re-foundation of Roman cultural memory through genealogy and humanitas T2 - Cultural memory in republican and Augustan Rome N2 - In the last two centuries BC, with the Republic limping towards its end, the cultivated ruling elite began to lose its moral and political authority.1 Its members not only held themselves responsible for the so-called crisis of tradition, but at the same time also conveyed the impression of a loss of memory, as if all Romans were suffering from some kind of amnesia or identity crisis.2 In particular, institutional figures such as pontiffs and augurs, who had preserved Rome’s memory throughout its history, were accused of neglecting their duties and, by extension, of allowing ancient practices and values to slowly disappear.3 Accordingly, Cicero and Varro, both perfect representatives of this elite, employed recurrent terms such as neglect (neglegentia/neglegere), involuntary abandon (amittere), oblivion (oblivio), vanishing of institutions (evanescere), and ignorance (ignoratio/ignorare) to describe this critical loss of information; they depicted the citizenry of Rome (civitas) as disoriented and estranged, incapable of sharing any common knowledge or values.
