Software platforms regularly introduce new features to remain competitive. While platform innovation is considered to be a critical success factor, adding certain features could hurt the ecosystem. If platform owners provide functionality that was previously provided by a contributor, the owners enter complementary product spaces. Complementary market entry frequently occurs on software platforms and is a major concern for third-party developers.
Divergent findings on the impact of complementary market entry call for the consideration of additional factors. As prior research neglected the third-party perspective, this contribution aims to address this gap. We explore the use of measures to prevent complementary market entry using a survey approach on browser platforms. The research model is tested with 655 responses among developer from Mozilla Firefox and Google Chrome. To explain countermeasures employment, developer’s attitude and perceived likelihood are important. The results reveal that developers employ countermeasures if complementary market entry is assessed negatively and perceived as likely for their extension. Differences among browser platforms concerning complementary market entry are identified. Product spaces of extensions being available on multiple platforms are less likely to be entered and more heavily protected. Implications for research and stakeholders, i.e. platform owners and contributors are discussed.
Modern browsers are digital software platforms, as they allow third parties to extend functionality by providing extensions. In a highly competitive environment, differentiation through provided functionality is a key factor for browser platforms. As the development of browsers progress, new functions are constantly being released. Browsers could thus enter complementary markets by adding functionality previously provided by third-party extensions, which is referred to as ‘platform coring’. Previous studies have missed the perspective of the parties involved. To address this gap, we conducted interviews with third-party and core developers in the security and privacy domain from Firefox and Chrome. This study provides three contributions. First, insights into stakeholder-specific issues concerning coring. Second, measures to prevent coring. Third, strategical guidance for developers and owners. Third-party vendors experienced and core developers confirmed that coring occurs on browser platforms. While developers with extrinsic motivations assess coring negatively, developers with intrinsic motivations perceive coring positively.
As AI technology is increasingly used in production systems, different approaches have emerged from highly decentralized small-scale AI at the edge level to centralized, cloud-based services used for higher-order optimizations. Each direction has disadvantages ranging from the lack of computational power at the edge level to the reliance on stable network connections with the centralized approach. Thus, a hybrid approach with centralized and decentralized components that possess specific abilities and interact is preferred. However, the distribution of AI capabilities leads to problems in self-adapting learning systems, as knowledgebases can diverge when no central coordination is present. Edge components will specialize in distinctive patterns (overlearn), which hampers their adaptability for different cases. Therefore, this paper aims to present a concept for a distributed interchangeable knowledge base in CPPS. The approach is based on various AI components and concepts for each participating node. A service-oriented infrastructure allows a decentralized, loosely coupled architecture of the CPPS. By exchanging knowledge bases between nodes, the overall system should become more adaptive, as each node can “forget” their present specialization.
Since more and more production tasks are enabled by Industry 4.0 techniques, the number of knowledge-intensive production tasks increases as trivial tasks can be automated and only non-trivial tasks demand human-machine interactions. With this, challenges regarding the competence of production workers, the complexity of tasks and stickiness of required knowledge occur [1]. Furthermore, workers experience time pressure which can lead to a decrease in output quality. Cyber-Physical Systems (CPS) have the potential to assist workers in knowledge-intensive work grounded on quantitative insights about knowledge transfer activities [2]. By providing contextual and situational awareness as well as complex classification and selection algorithms, CPS are able to ease knowledge transfer in a way that production time and quality is improved significantly. CPS have only been used for direct production and process optimization, knowledge transfers have only been regarded in assistance systems with little contextual awareness. Embedding production and knowledge transfer optimization thus show potential for further improvements. This contribution outlines the requirements and a framework to design these systems. It accounts for the relevant factors.
While school supervision structures in the German Länder were extensively reformed during the last decades, systematic analyses of these reforms are missing. This chapter contributes to this research gap by providing an overview of the implemented reforms of school supervision structures in the German Länder. The effects of these reforms are analysed in order to answer the question of whether a convergence of school supervision systems is a result of these reforms. In a first step, a distinction is made to identify system-changing reforms. Although a decrease of the number or a concentration on one school supervision system is not a result of the analysis, it is argued that there is a convergence of school supervision structures, as a clear trend against school supervision systems with lower school supervisory boards can be observed.
Singles in the city
(2021)
More people than ever are living in cities, and in these cities, more and more people are living alone. Using the example of Vienna, this paper investigates the subjective well-being of single households in the city. Previous research has identified positive and negative aspects of living alone (e.g., increased freedom vs. missing social embeddedness). We compare single households with other household types using data from the Viennese Quality of Life Survey (1995–2018). In our analysis, we consider overall life satisfaction as well as selected dimensions of subjective wellbeing (i.e., housing, financial situation, main activity, family, social contacts, leisure time). Our findings show that the subjective well-being of single households in Vienna is high and quite stable over time. While single households are found to have lower life satisfaction than two-adult households, this result is mainly explained by singles reporting lower satisfaction with family life. Compared to households with children, singles are more satisfied with their financial situation, leisure time and housing, which helps to offset the negative consequences of missing family ties (in particular with regard to single parents).
From laggards to leaders
(2021)
The 2015 Paris Agreement on climate change embraces the participation of non-state actors in a separate governance track – the ‘Non-state actor zone for global action’ (nazca) – that runs alongside the formal track of unfccc negotiations and the implementation of the Paris Agreement by State Parties through ‘nationally determined contributions’. unfccc Secretariat is entrusted with orchestrating non-state global and transnational initiatives, partnerships and networks. The involvement of non-state actors in the implementation of the Paris Agreement helps to address an action gap by countries that are unable or unwilling to implement ambitious ndcs.
However, the increased prominence of initiatives driven by non-state actors also increases their direct and indirect influence on processes and rules which raises a number of questions with regards to the legitimacy of action and the democratic deficit of the global climate regime. Balancing legitimacy with effectiveness requires non-state initiatives to ensure transparent and inclusive governance, and accountability towards progress against their goals and pledges.
Despite its encouragement towards private initiatives, the Paris Agreement creates surprisingly little regulatory space for non-state actors to gain hold. Neither are there measures that would link ndcs to nazca initiatives, nor are functional requirements such as transparency or reporting extended to non-state initiatives. While the Paris Agreement marks an important step towards harnessing private sector ability and ambition for climate action, more remains to be done to create a truly enabling framework for private action to strive and complement public efforts to address climate change.

Bundesrechnungshof
(2021)
Der Bundesrechnungshof schaut mittlerweile auf eine über 300 jährige Geschichte der Finanzkontrolle zurück (vgl. Engels 2014). Auch wenn Aufgaben und Organisation damaliger Rechenkammern bestenfalls rudimentär mit den Einrichtungen moderner Finanzkontrolle vergleichbar sind, so legten sie doch einst deren Grundstein. Heute ist der Bundesrechnungshof eine oberste Bundesbehörde und prüft laut Artikel 114 Abs. 2 GG die „Rechnung sowie die Wirtschaftlichkeit und Ordnungsmäßigkeit der Haushalts- und Wirtschaftsführung des Bundes.“ Weitere Regelungen für den Bundesrechnungshof finden sich in der Bundeshaushaltsordnung (BHO, hier Teil V Rechnungsprüfung bis Teil VIII Entlastung, §§ 88 bis 114) und im Bundesrechnungshofgesetz (BRHG vom 11.07.1985, mit letzter Änderung vom 05.02.2009).
Militär und Moral sind scheinbar zwei sich gegenseitig ausschließende Begriffe. Kriegerische Konflikte und die Tötung von Menschen kommen uns gänzlich unmoralisch vor. Wenn überhaupt, ist die Kampfmoral (Biehl, Heiko. 2012. Einsatzmotivation und Kampfmoral. In Militärsoziologie – Eine Einführung. 2., aktualisierte und ergänzte Aufl., Hrsg. Nina Leonhard und Ines-Jacqueline Werkner, 447–474. Wiesbaden: VS Verlag für Sozialwissenschaften.) ein gängiges Konzept. Nichtsdestotrotz wird im vorliegenden Beitrag angenommen, dass das Militär moralisch handeln kann. Es wird argumentiert, dass das Militär mit widersprüchlichen moralischen und rechtlichen Erwartungshaltungen konfrontiert wird und diese Erwartungen in Entscheidungen übersetzt. Dadurch gerät das Militär jedoch stetig in moralische Entscheidungsdilemmata. Am Beispiel der Seenotrettung im Mittelmeer zwischen 2015 und 2018 soll exemplarisch gezeigt werden, dass das Militär sowohl eine Situationsmoral und moralische Routinen entwickelt als auch Vermeidungsstrategien verfolgt, die jegliche Moralerwartungen von der Organisation fernhalten. Der Beitrag arbeitet hierbei mit einem Moralbegriff philosophischer Provenienz und zeigt verschiedene analytische Dimensionen auf, die zur Analyse von Moral von Organisationen beitragen können.
Demokratie und politische Bildung stehen in einem sich zugewandten Verhältnis. Doch folgt daraus, dass politische Urteile stets demokratisch sein müssen? Der Beitrag diskutiert diese Frage vor dem Hintergrund der derzeitigen Debatte um antidemokratische Bewegungen in der Gesellschaft, der Rolle politischer Bildung als Förderin von Demokratie und der individuellen Herausforderung für Lehrpersonen in der Unterrichtspraxis.
Qualitative Inhaltsanalyse
(2021)
Die qualitative Inhaltsanalyse dient als Auswertungsinstrument für Textmaterial, kann aber auch für die Analyse von Ton- und Bildmaterial genutzt werden. Anders als die quantitative Inhaltsanalyse zielt sie darauf ab, dem Material auch Informationen zu entnehmen, auf die ausschließlich interpretativ geschlossen werden kann. Die qualitative Inhaltsanalyse knüpft an die hermeneutische Tradition des Verstehens an. Der Verstehensprozess wird jedoch in einen vordefinierten, theorie- und regelgeleiteten Forschungsablauf gebettet, um dem wissenschaftlichen Anspruch an Systematik und Intersubjektivität nachzukommen.
Land Brandenburg
(2021)
Das über 860 Jahre alte deutsche Land BB liegt im Nordosten Ds zwischen Elbe und Oder. Es umschließt die Bundeshauptstadt BE, die als Einheitsgemeinde zugleich ein eigenes Land bildet. Potsdam als Landeshauptstadt ist mit 176.000 E. die größte Stadt in BB. Mit 29.482 qkm (8,3 % von D) zählt die Mark zu den flächenreichsten Bundesländern.
This paper starts from the premise that Western states are connected to some of the harms refugees suffer from. It specifically focuses on the harm of acts of misrecognition and its relation to epistemic injustice that refugees suffer from in refugee camps, in detention centers, and during their desperate attempts to find refuge. The paper discusses the relation between hermeneutical injustice and acts of misrecognition, showing that these two phenomena are interconnected and that acts of misrecognition are particularly damaging when (a) they stretch over different contexts, leaving us without or with very few safe spaces, and (b) they dislocate us, leaving us without a community to turn to. The paper then considers the ways in which refugees experience acts of misrecognition and suffer from hermeneutical injustice, using the case of unaccompanied children at the well-known and overcrowded camp Moria in Greece, the case of unsafe detention centers in Libya, and the case of the denial to assistance on the Mediterranean and the resulting pushbacks from international waters to Libya as well as the preventable drowning of refugees in the Mediterranean to illustrate the arguments. Finally, the paper argues for specific duties toward refugees that result from the prior arguments on misrecognition and hermeneutical injustice.
The rising standard language in Early New High German (1350–1650) provides particularly interesting cases for the question of missing heads on all levels of language structure. A well-known example are subordinate clauses lacking a finite auxiliary verb, traditionally called Afinite Constructions. Based on new data, drawn from two treebanks of Early New High German, the present paper will briefly sketch the distribution of ACs, before establishing that they are in fact a type of ellipsis and do not cluster with other non-finite clauses in German. The remainder of the paper addresses the question what kind of information is missing in ACs and how this information is retrieved. Obviously, auxiliary drop in ENHG represents a type of ellipsis rarely attested in present-day German.
Wilhelm Herzbergs „Das Mädchen von Tanger“ ist an zentraler Stelle seiner Jüdischen Familienpapiere als Binnenerzählung angelegt. In diesem konkreten Fall handelt es sich um eine gerahmte Binnenerzählung, die als fingierte Quelle dem Leser Authentizität vermitteln soll. Die literarischen Vorbilder dieses Genres liegen sowohl in der klassischen indischen und persischen Literatur als auch in der homerischen Odyssee. Die Binnenerzählung wurde von Goethe in seinen Unterhaltungen deutscher Auswanderer (1795) weiterentwickelt. Im 19.Jahrhundert wurde sie stilbildend und erfreute sich großer Beliebtheit. Sie verfügt über eine eigene epische Erzählstruktur und versteht sich als „Erzählung in der Erzählung“ . Dadurch kann sie noch zusätzliche Akzente setzen und zugleich moralische Anleitung für die Leserschaftbereithalten.
