The new Stateness Index (StIx) contributes to the conceptual and analytical debate on stateness and state fragility. StIx is a tool for measuring stateness and state quality since 1950 that includes country-ranking through aggregated and disaggregated data to advance performance comparison and policy analysis. This article first sums up the main theoretical aspects, followed by descriptive results.

T1 - Are Biases Contagious? The Influence of Communication on Motivated Beliefs N2 - This paper examines the potential reinforcement of motivated beliefs when individuals with identical biases communicate. We propose a controlled online experiment that allows to manipulate belief biases and the communication environment. We find that communication, even among like-minded individuals, diminishes motivated beliefs if it takes place in an environment without previously declared external opinions. In the presence of external plural opinions, however, communication does not reduce but rather aggravates motivated beliefs. Our results indicate a potential drawback of the plurality of opinions - it may create communication environments wherein motivated beliefs not only persist but also become contagious within social networks.

Die mainEUropa-Blogs wollten über ausgewählte Aspekte der EU-Politik aktuell, knapp und leicht verständlich informieren; damit haben sie dem EU-Geschehen der Jahre 2017 bis 2021 aus jeweils aktuellen Anlässen den Puls genommen und zu einem besseren Verständnis der EU-Politik- und Entscheidungsprozesse beigetragen. Die Blog-Themen sind breit gefächert und bilden somit ausgewählte Ereignisse und Weichenstellungen aus der jüngeren Integrationsgeschichte ab. Die Themen reichen über klimapolitische Beschlüsse, das Ringen um den Erhalt bzw. die Wiederherstellung der Rechtstaatlichkeit in einigen EU-Mitgliedstaaten, das Endlos-Drama des Brexits, wichtige Wahlen in der EU und ausgewählten Mitgliedstaaten bis hin zu neuen Entwicklungen in der EU-Außen-, Sicherheits- und Verteidigungspolitik sowie zu den überraschend zupackenden Antworten der EU auf die Covid-19-Pandemie. Ein Blick auf die europapolitische Agenda der im Dezember 2021 angetretenen rot-grün-gelben Ampel-Bundesregierung beschließt die Reihe. Denn 2021 endete auch das die mainEUropa-Blogs tragende Jean Monnet Projekt, so dass das vorliegende fünfte Jean Monnet Paper auch das letzte sein wird.

T1 - Unilateral Environmental Policy and Offshoring N2 - Expanding on a general equilibrium model of offshoring, we analyze the effects of a unilateral emissions tax increase on the environment, income, and inequality. Heterogeneous firms allocate labor across production tasks and emissions abatement, while only the most productive can benefit from lower labor and/or emissions costs abroad and offshore. We find a non-monotonic effect on global emissions, which decline if the initial difference in emissions taxes is small. For a sufficiently large difference, global emissions rise, implying emissions leakage of more than 100%. The underlying driver is a global technique effect: While the emissions intensity of incumbent non-offshoring firms declines, the cleanest firms start offshoring. Moreover, offshoring firms become dirtier, induced by a reduction in the foreign effective emissions tax in general equilibrium. Implementing a BCA prevents emissions leakage, reduces income inequality in the reforming country, but raises inequality across countries. T3 - Würzburg Economic Papers (W. E.

Dijkstra’s algorithm has been a popular solution for the shortest path problem, but repetitive use of it to find multiple paths is not scalable. The Multiple Disjoint Path Algorithm (MDPAlg), published in 2021, proposes the use of a single full graph to construct multiple disjoint paths. This paper proposes modifications to the algorithm to include a delay constraint, which is important in time-sensitive applications. Different delay constraint least-cost routing algorithms are compared in a comprehensive manner to evaluate the benefits of the adapted MDPAlg algorithm. Fault tolerance, and thereby reliability, is ensured by generating multiple link-disjoint paths from source to destination.

P4 is a language used in software-defined networking to program the data plane. The data plane can profit in many circumstances when it is allowed to manage its state without any detour over a controller. This work is based on a previous study by investigating the potential and performance of add-on-miss insertions of state by the data plane. The state keeping capabilities of P4 are limited regarding the amount of data and the update frequency. We follow the tentative specification of an upcoming portable-NIC-architecture and implement these changes into the software P4 target T4P4S. We show that insertions are possible with only a slight overhead compared to lookups and evaluate the influence of the rate of insertions on their latency.

However, transparently implementing packet distribution over multiple paths within the core of the network faces multiple challenges including scalability to a large number of customers, low latency, and high-capacity packet processing requirements. In this paper, we offload congestion-aware multipath packet scheduling to a smartNIC. However, such hardware acceleration faces multiple challenges due to programming language and platform limitations. We implement different multipath schedulers in P4 with different complexity in order to cope with dynamically changing path capacities. Using testbed measurements, we show that our CMon scheduler, which monitors path congestion in the data plane and dynamically adjusts scheduling weights for the different paths based on path state information, can process more than 3.5 Mpps packets 25 μs latency.

We prove the accuracy of the online-algorithm offline with timestamp data and compare the derived bounds to the measured delay and backlog. We also do a proof-of- concept of the online-algorithm, implement it in LabVIEW and compare its performance to the timestamp logging by CPU load and data-size of the log-file.

Especially, in the light of future large scale deployments and industrial use cases, a detailed analysis of the performance and utilization with regard to latency and service times constraints is crucial. To this end, a fine granular investigation of the Network Function (NF) based core system and the duration for all the tasks performed by these services is necessary.

Protocols like TCP try to solve this problem by resending the lost packets. However, retransmissions consume a lot of time and are cumbersome for the transmission of critical data. Multipath solutions are quite common to address this reliability issue and are available on almost every layer of the ISO/OSI model. We propose a solution based on a P4 network to duplicate packets in order to send them to their destination via multiple routes. The last network hop ensures that only a single copy of the traffic is further forwarded to its destination by adopting a concept similar to Bloom filters. Besides, if fast delivery is requested we provide a P4 prototype, which randomly forwards the packets over different transmission paths. For reproducibility, we implement our approach in a container-based network emulation system called Kathará.

Konzeptualisierung eines Phänomens zwischen Selbstregierung und Selbstregelung N2 - For decades autonomy has been utilised as a concept in various social sciences, like sociology, political science, law and philosophy. Certain concepts of autonomy have always reflected the needs of the respective disciplines that made use of the term, but also ever infringed on the interpretation of autonomy in other disciplines. Most notably, conceptualisations of international and constitutional law have found their way into bordering sciences, like political science. The result: a legal positivist view prevailing in the conceptualisations of autonomy within political and administrative sciences. As this working paper points out, this perspective does not do justice to the complex phenomenon autonomy is or may be in social and political reality. Hence, the paper argues for a differentiated concept of autonomy, splitting it into autonomy claims, actors, process, rights and powers, regimes, and their institutions. The empirical world suggests a salience of formally and informally lived types of autonomy, especially in Latin America, due to the region’s indigenous population often living outside of, or within the limited reach of the state. Therefore, the paper aims to incorporate the dimension of informality – lacking in previous legal positivist approaches. Autonomy regimes could be entrenched in international, constitutional, or secondary law, or they could be tolerated by the state or seized by autonomy claimants by force. From a theoretical or conceptual perspective, the dimension of (in)formality facilitates the incorporation of autonomy into the discussion on governance and government, mostly on the local or regional level. Thus, the paper establishes autonomy regimes as a concept located at the verges of (self-)government and (self-)governance. N2 - Seit Jahrzehnten wird der Begriff Autonomie in verschiedenen Sozialwissenschaften, wie Soziologie, Politikwissenschaft, Recht und Philosophie verwendet. Die jeweiligen Verständnisse von Autonomie spiegelten stets die Bedürfnisse dieser Disziplinen wider. Dabei beeinflussen etablierte Konzepte zu Autonomie häufig angrenzende Disziplinen. Vor allem Autonomieverständnisse aus dem Völker- und Verfassungsrecht haben ihren Weg in andere Wissenschaften gefunden. Dementsprechend herrschen auch in der Politik- und Verwaltungswissenschaft rechtspositivistische Sichtweisen zu Autonomie vor. Wie dieses Working Paper zeigt, wird diese Perspektive dem komplexen Phänomen, das Autonomie in der sozialen und politischen Realität ist oder sein kann, nicht gerecht. Das Paper plädiert daher für einen differenzierten Autonomiebegriff, der Autonomieansprüche, -akteure, -prozesse, -rechte und -befugnisse, -regime und -institutionen unterscheidet. Die Empirie zeigt, dass formell und informell gelebte Formen der Autonomie von Bedeutung sind – vor allem in Lateinamerika, da Autonomiebestrebungen der indigenen Bevölkerung der Region häufig außerhalb staatlicher Reichweite oder im Kontext schwacher Staatlichkeit gestellt werden. Daher zielt das Paper darauf ab, die Dimension der (In)Formalität in das Konzept von Autonomie zu integrieren, die in früheren positivistischen Ansätzen fehlte. Autonomieregime können im internationalen Recht, in der Verfassung oder im Sekundärrecht verankert sein. Darüber hinaus können sie vom Staat geduldet oder von Akteuren, die Autonomie für sich beanspruchen, mit Gewalt durchgesetzt werden. Aus theoretischer oder konzeptioneller Sicht ermöglicht der Rückbezug auf die Informalität es, Autonomie in die Diskussion über Governance und Government einzubetten, vorwiegend auf lokaler oder regionaler Ebene. Autonomieregime werden hier deshalb als ein Konzept definiert, das an der Grenze zwischen (Selbst-)Regierung und (Selbst-) Regelung angesiedelt ist.

We are a group of scholars in media ethics, practical theology/religious education, and human computer interaction, who have been engaged in this discourse since 2017. A natural starting point is our study of BlessU2, a “blessing robot,” a device which received considerable recognition from the global public at the Wittenberg 500th reformation anniversary in 2017. We thus begin with the results of this study. Secondly, we will briefly address the relevant theses from Gabriele Trovato et al., as presented in their 2019 article on so-called theomorphic robots – followed by our interdisciplinary discussion of their approach. Finally, we draw conclusions for further work on the field of “religious robots.” Somewhat more carefully: Section 1 offers starting points within the perspectives of Christian religious practice: here, the blessing robot is both cause and occasion for doing religion and theologizing in the context of existential questions (1.1). We continue with perceptions in the field of religion regarding “Discursive Design Theory” (1.2). The interaction of humans with computers as posing questions for theological standardization of religious practice is focused upon in 1.3. Section 2 reconstructs the HRI/HCI-initiative to develop theomorphic robots in a twofold manner, i.e., the idea of developing theomorphic robots (2.1) and the concept of theomorphic robots: Questions and objections (2.2). In this part of the article we raise discussion points concerning the relationship between technology and religion and the need for sharpening the understanding of religion within the research field. Section 3 closes with propositions and alternatives.

Eliciting subjects’ receptiveness to rightwing populism and their perceived relative income positions in a representative survey of German households, we find that people with pessimistic beliefs about their income position are more attuned to populist statements. Key to understanding the misperception-populism relationship are strong gender differences in the mechanism: men are much more likely to channel their discontent into affection for populist ideas.

Due to high uncertainty about relevant determinants, trend patterns and the correct estimation method, we propose in this paper a simple alternative approach derived from a standard macro model. Starting from a loss function, neutral periods can be determined in which a neutral real interest rate is observable. Using these values, a medium-term trend for a neutral interest rate can be determined. An application to the USA shows that our simple calculation of a neutral interest rate delivers comparable results to existing studies. A Taylor rule based on our neutral interest rate also does a fairly good job of explaining US monetary policy over the past 60 years. T3 - Würzburg Economic Papers (W. E.
