International law is constantly navigating the tension between preserving the status quo and adapting to new exigencies. 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.
When realizing a programming language as VM, implementing behavior as part of the VM, as primitive, usually results in reduced execution times. But supporting and developing primitive functions requires more effort than maintaining and using code in the hosted language since debugging is harder, and the turn-around times for VM parts are higher. Furthermore, source artifacts of primitive functions are seldom reused in new implementations of the same language. And if they are reused, the existing API usually is emulated, reducing the performance gains. Because of recent results in tracing dynamic compilation, the trade-off between performance and ease of implementation, reuse, and changeability might now be decided adversely.
In this work, we investigate the trade-offs when creating primitives, and in particular how large a difference remains between primitive and hosted function run times in VMs with tracing just-in-time compiler. To that end, we implemented the algorithmic primitive BitBlt three times for RSqueak/VM. RSqueak/VM is a Smalltalk VM utilizing the PyPy RPython toolchain. We compare primitive implementations in C, RPython, and Smalltalk, showing that due to the tracing just-in-time compiler, the performance gap has lessened by one magnitude to one magnitude.
Since the end of the Apartheid international tourism in South Africa has increasingly gained importance for the national economy. The centre of this PKS issue’s attention is a particular form of tourism: Township tourism, i.e. guided tours to the residential areas of the black population. About 300,000 tourists per year visit the townships of Cape Town. The tours are also called Cultural, Social, or Reality Tours. The different aspects of township tourism in Cape Town were subject of a geographic field study, which was undertaken during a student research project of Potsdam University in 2007. The text at hand presents the empirical results of the field study, and demonstrates how townships are constructed as spaces of tourism.
Version control is a widely used practice among software developers. It reduces the risk of changing their software and allows them to manage different configurations and to collaborate with others more efficiently. This is amplified by code sharing platforms such as GitHub or Bitbucket. Most version control systems track files (e.g., Git, Mercurial, and Subversion do), but some programming environments do not operate on files, but on objects instead (many Smalltalk implementations do). Users of such environments want to use version control for their objects anyway. Specialized version control systems, such as the ones available for Smalltalk systems (e.g., ENVY/Developer and Monticello), focus on a small subset of objects that can be versioned. Most of these systems concentrate on the tracking of methods, classes, and configurations of these. Other user-defined and user-built objects are either not eligible for version control at all, tracking them involves complicated workarounds, or a fixed, domain-unspecific serialization format is used that does not equally suit all kinds of objects. Moreover, these version control systems that are specific to a programming environment require their own code sharing platforms; popular, well-established platforms for file-based version control systems cannot be used or adapter solutions need to be implemented and maintained.
To improve the situation for version control of arbitrary objects, a framework for tracking, converting, and storing of objects is presented in this report. It allows editions of objects to be stored in an exchangeable, existing backend version control system. The platforms of the backend version control system can thus be reused. Users and objects have control over how objects are captured for the purpose of version control. Domain-specific requirements can be implemented. The storage format (i.e. the file format, when file-based backend version control systems are used) can also vary from one object to another. Different editions of objects can be compared and sets of changes can be applied to graphs of objects. A generic way for capturing and restoring that supports most kinds of objects is described. It models each object as a collection of slots. Thus, users can begin to track their objects without first having to implement version control supplements for their own kinds of objects. The proposed architecture is evaluated using a prototype implementation that can be used to track objects in Squeak/Smalltalk with Git. The prototype improves the suboptimal standing of user objects with respect to version control described above and also simplifies some version control tasks for classes and methods as well. It also raises new problems, which are discussed in this report as well.
Towards computer science
(1998)
The correctness of model transformations is a crucial element for the model-driven engineering of high quality software. A prerequisite to verify model transformations at the level of the model transformation specification is that an unambiguous formal semantics exists and that the employed implementation of the model transformation language adheres to this semantics. However, for existing relational model transformation approaches it is usually not really clear under which constraints particular implementations are really conform to the formal semantics. In this paper, we will bridge this gap for the formal semantics of triple graph grammars (TGG) and an existing efficient implementation. Whereas the formal semantics assumes backtracking and ignores non-determinism, practical implementations do not support backtracking, require rule sets that ensure determinism, and include further optimizations. Therefore, we capture how the considered TGG implementation realizes the transformation by means of operational rules, define required criteria and show conformance to the formal semantics if these criteria are fulfilled. We further outline how static analysis can be employed to guarantee these criteria.
Touring Katutura!
(2016)
Guided sightseeing tours of the former township of Katutura have been offered in Windhoek since the mid-1990s. City tourism in the Namibian capital had thus become, at quite an early point in time, part of the trend towards utilising poor urban areas for purposes of tourism – a trend that set in at the beginning of the same decade. Frequently referred to as “slum tourism” or “poverty tourism”, the phenomenon of guided tours around places of poverty has not only been causing some media sensation and much public outrage since its emergence; in the past few years, it has developed into a vital field of scientific research, too. “Global Slumming” provides the grounds for a rethinking of the relationship between poverty and tourism in world society.
This book is the outcome of a study project of the Institute of Geography at the School of Cultural Studies and Social Science of the University of Osnabrueck, Germany. It represents the first empirical case study on township tourism in Namibia. It focuses on four aspects:
1. Emergence, development and (market) structure of township tourism in Windhoek
2. Expectations/imaginations, representations as well as perceptions of the township and its inhabitants from the tourist’s perspective
3. Perception and assessment of township tourism from the residents’ perspective
4. Local economic effects and the poverty-alleviating impact of township tourism
The aim is to make an empirical contribution to the discussion around the tourism-poverty nexus and to an understanding of the global phenomenon of urban poverty tourism.
Touching at a Distance
(2023)
Studies the capacity of Shakespeare’s plays to touch and think about touchBased on plays from all major genres: Hamlet, The Tempest, Richard III, Much Ado About Nothing and Troilus and CressidaCentres on creative, close readings of Shakespeare’s plays, which aim to generate critical impulses for the 21st century readerBrings Shakespeare Studies into touch with philosophers and theoreticians from a range of disciplinary areas – continental philosophy, literary criticism, psychoanalysis, sociology, phenomenology, law, linguistics: Friedrich Nietzsche, Maurice Blanchot, Jacques Lacan, Luce Irigaray, Jacques Derrida, Roland Barthes, Niklas Luhmann, Hans Blumenberg, Carl Schmitt, J. L. AustinTheatre has a remarkable capacity: it touches from a distance. The audience is affected, despite their physical separation from the stage. The spectators are moved, even though the fictional world presented to them will never come into direct touch with their real lives. Shakespeare is clearly one of the master practitioners of theatrical touch. As the study shows, his exceptional dramaturgic talent is intrinsically connected with being one of the great thinkers of touch. His plays fathom the complexity and power of a fascinating notion – touch as a productive proximity that is characterised by unbridgeable distance – which philosophers like Friedrich Nietzsche, Maurice Blanchot, Jacques Derrida, Luce Irigaray and Jean-Luc Nancy have written about, centuries later. By playing with touch and its metatheatrical implications, Shakespeare raises questions that make his theatrical art point towards modernity: how are communities to form when traditional institutions begin to crumble? What happens to selfhood when time speeds up, when oneness and timeless truth can no longer serve as reliable foundations? What is the role and the capacity of language in a world that has lost its seemingly unshakeable belief and trust in meaning? How are we to conceive of the unthinkable extremes of human existence – birth and death – when the religious orthodoxy slowly ceases to give satisfactory explanations? Shakespeare’s theatre not only prompts these questions, but provides us with answers. They are all related to touch, and they are all theatrical at their core: they are argued and performed by the striking experience of theatre’s capacities to touch – at a distance
Scrollytellings are an innovative form of web content. Combining the benefits of books, images, movies, and video games, they are a tool to tell compelling stories and provide excellent learning opportunities. Due to their multi-modality, creating high-quality scrollytellings is not an easy task. Different professions, such as content designers, graphics designers, and developers, need to collaborate to get the best out of the possibilities the scrollytelling format provides. Collaboration unlocks great potential. However, content designers cannot create scrollytellings directly and always need to consult with developers to implement their vision. This can result in misunderstandings. Often, the resulting scrollytelling will not match the designer’s vision sufficiently, causing unnecessary iterations. Our project partner Typeshift specializes in the creation of individualized scrollytellings for their clients. Examined existing solutions for authoring interactive content are not optimally suited for creating highly customized scrollytellings while still being able to manipulate all their elements programmatically. Based on their experience and expertise, we developed an editor to author scrollytellings in the lively.next live-programming environment. In this environment, a graphical user interface for content design is combined with powerful possibilities for programming behavior with the morphic system. The editor allows content designers to take on large parts of the creation process of scrollytellings on their own, such as creating the visible elements, animating content, and fine-tuning the scrollytelling. Hence, developers can focus on interactive elements such as simulations and games. Together with Typeshift, we evaluated the tool by recreating an existing scrollytelling and identified possible future enhancements. Our editor streamlines the creation process of scrollytellings. Content designers and developers can now both work on the same scrollytelling. Due to the editor inside of the lively.next environment, they can both work with a set of tools familiar to them and their traits. Thus, we mitigate unnecessary iterations and misunderstandings by enabling content designers to realize large parts of their vision of a scrollytelling on their own. Developers can add advanced and individual behavior. Thus, developers and content designers benefit from a clearer distribution of tasks while keeping the benefits of collaboration.
In this study we examine the tonal organization of a series of recordings of liturgical chants, sung in 1966 by the Georgian master singer Artem Erkomaishvili. This dataset is the oldest corpus of Georgian chants from which the time synchronous F0-trajectories for all three voices have been reliably determined (Müller et al. 2017). It is therefore of outstanding importance for the understanding of the tuning principles of traditional Georgian vocal music.
The aim of the present study is to use various computational methods to analyze what these recordings can contribute to the ongoing scientific dispute about traditional Georgian tuning systems. Starting point for the present analysis is the re-release of the original audio data together with estimated fundamental frequency (F0) trajectories for each of the three voices, beat annotations, and digital scores (Rosenzweig et al. 2020). We present synoptic models for the pitch and the harmonic interval distributions, which are the first of such models for which the complete Erkomaishvili dataset was used. We show that these distributions can be very compactly be expressed as Gaussian mixture models, anchored on discrete sets of pitch or interval values for the pitch and interval distributions, respectively. As part of our study we demonstrate that these pitch values, which we refer to as scale pitches, and which are determined as the mean values of the Gaussian mixture elements, define the scale degrees of the melodic sound scales which build the skeleton of Artem Erkomaishvili’s intonation. The observation of consistent pitch bending of notes in melodic phrases, which appear in identical form in a group of chants, as well as the observation of harmonically driven intonation adjustments, which are clearly documented for all pure harmonic intervals, demonstrate that Artem Erkomaishvili intentionally deviates from the scale pitch skeleton quite freely. As a central result of our study, we proof that this melodic freedom is always constrained by the attracting influence of the scale pitches. Deviations of the F0-values of individual note events from the scale pitches at one instance of time are compensated for in the subsequent melodic steps. This suggests a deviation-compensation mechanism at the core of Artem Erkomaishvili’s melody generation, which clearly honors the scales but still allows for a large degree of melodic flexibility. This model, which summarizes all partial aspects of our analysis, is consistent with the melodic scale models derived from the observed pitch distributions, as well as with the melodic and harmonic interval distributions. In addition to the tangible results of our work, we believe that our work has general implications for the determination of tuning models from audio data, in particular for non-tempered music.
Toeplitz operators, and ellipticity of boundary value problems with global projection conditions
(2003)
This paper studies the persistence of daily returns of 21 German stocks from 1960 to 2008. We apply a widely used test based upon the modified R/S-Method by Lo [1991]. As an extension to Lux [1996] and Carbone et al. [2004] and in analogy to moving average or moving volatility, the statistics is calculated for moving windows of length 4, 8, and 16 years for every time series. Periods of persistence or long memory in returns can be found in some but not all time series. Robustness of results is verified by investigating stationarity and short memory effects.
Time series analysis
(2004)
This volume offers new arguments and perspectives in the ongoing debate about the optimal analysis of verb movement, mainly, but not exclusively, in German. Fanselow and Meinunger deal with verb second (V2) movement in German main clauses. Fanselow argues that head movement of the substitution type follows the standard minimalist conceptions of Merge and Move and is therefore not subject to the same objections as head movement as head adjunction which violates Chomsky's minimalist extension condition, operates countercyclically, and fails to let the moved head c-command its trace. Fanselow argues for V2 movement as head movement of the substitution type. Meinunger discusses a restriction on V2 movement imposed by phrases like "mehr als" ('more than'), as in "Der Wert hat sich weit mehr als verdreifacht" ('the value has far more than tripled') where V2 movement is ruled out (cf. *"Der Wert verdreifachte sich mehr als"). Meinunger claims that this restriction is best analysed in phonological terms: the preposition/complementiser "als" acts as a prefixal clitic to its host, the finite verb, which therefore may not move without it. With respect to the V2 debate, Meinunger argues for an interface perspective. He shows that V2 is restricted from both the conceptual and the phonological interface. Vogel, finally, discusses the syntax of clause-final verbal complexes and their dialectal variation in German. He compares three different syntactic analyses, a minimalist head movement analysis, a minimalist XP movement analysis, and an Optimality theoretic PF movement analysis. The three accounts are evaluated relative to the additional assumptions they have to make, the complications they face and how they fit the observations. Vogel argues in favour of the phonologically oriented OT analysis because of its ability to create a direct link between the coming about of a particular word order pattern and its basically phonological trigger. Each of the three papers recognises the relevance of surface forms in the analysis of German verb movement. They differ, however in the extent to which phonological aspects take part in the explanations they offer.
Theories and concepts
(2020)
Urban Change and Citizenship in Times of Crisis addresses the fact that in the beginning of the twenty-first century the majority of the world’s population is urbanised, a social fact that has turned cities more than ever into focal sites of social change. Multiple economic and political strategies, employed by a variety of individual and collective actors, on a number of scales, constitute cities as contested spaces that hold opportunities as well as restrictions for their inhabitants. While cities and urban spaces have long been of central concern for the social sciences, today, classical sociological questions about the city acquire new meaning: Can cities be spaces of emancipation, or does life in the modern city entail a corrosion of citizenship rights? Is the city the focus of societal transformation processes, or do urban environments lose importance in shaping social reality and economic relationships? Furthermore, new questions urgently need to be asked: What is the impact of different historical phenomena such as neo-liberal restructuring, financial and economic crises, or migration flows, as well as their respective counter-movements, on the structure of contemporary cities and on the citizenship rights of city inhabitants? The three volumes address such crucial questions thereby opening up new spaces of debate on both the city and new developments of urbanism.
The contributions to Theories and Concepts offer new theoretical reflections on the city in a philosophical and historical perspective as well as fresh empirical analyses of social life in urban contexts. Chapters not only critically revisit classical and modern philosophical considerations about the nature of cities but no less discuss normative philosophical reflections of urban life and the role of religion in historical processes of the emergence of cities. Composed around the question whether there can be such a thing as a ‘successful city’, this volume addresses issues of urban political subjectivities by considering the city’s role in historical processes of emancipation, the fight for citizenship rights, and today’s challenges and opportunities with regard to promoting social justice, integration, and diversity. Consequentially, theory-driven empirical analyses offer new insight into ways of solving problems in urban contexts and a genuine approach to analyse the Social Quality in cities.

“The UN Peacebuilding Commission – Lessons from Sierra Leone” by political scientist Andrea Iro is an assessment of the United Nations Peacebuilding Commission (PBC) and the United Nations Peacebuilding Fund (PBF) by analysing their performance over the last two years in Sierra Leone, one of the first PBC focus countries. The paper explores the key question of how the PBC/PBF’s mandate has been translated into operational practice in the field. It concludes that though the overall impact has been mainly positive and welcomed by the country, translating the general mandate into concrete activities remains a real challenge at the country level.

The Tetrarchy as Ideology
(2023)
The 'Tetrarchy', the modern name assigned to the period of Roman history that started with the emperor Diocletian and ended with Constantine I, has been a much-studied and much-debated field of the Roman Empire. Debate, however, has focused primarily on whether it was a true 'system' of government, or rather a collection of ad-hoc measures undertaken to stabilise the empire after the troubled period of the 3rd century CE. The papers collected here aim to go beyond this question and to present an innovative approach to a fascinating period of Roman history by understanding the Tetrarchy not as a system of government, but primarily as a political language. Their focus thus lies on the language and ideology of the imperial college and court, on the performance of power in imperial ceremonies, the representation of the emperors and their enemies in the provinces of the Roman world, as well as on the afterlife of Tetrarchic power in the Constantinian period.
Like in all countries in transition, the tax as well as the transfer system have been under serious reform pressures. The socialistic systems were not able to fulfill the necessary functions in providing a certain degree of redistribution and social security, which are inevitable for social oriented market economies. Increasing income and wage differentiation is one of the most important prerequisites for a market oriented ability to pay tax system. But in the transformation period, numerous quasi-legal or even illegal property transactions have taken place, thus leading to wealth concentrations on the one hand while as consequence of the bankruptcy of socialism, enormous poverty problems have arisen on the other. For the political acceptance of the transformation process it is of utmost importance that an efficient and fair tax system is implemented and social security is organised by the state on a level which secures at least the physical minimum of subsistence or – if economically possible – even a social-cultural minimum. Whether the state should go further in providing compulsory social insurance systems has been a hotly debated topic for decades even in the welfare and social states of the Western type. Whereas the basic security systems have to be financed by general tax revenue, for a compulsory social insurance system – due to the insurance character – special earmarked social security contribution are held necessary. Both public goods and services as well as at least basic security have to be financed by total tax revenue. For the acceptance and fairness of the whole system the total redistributive effect of both sides of the budget – the tax system as well as the expenditure system – are decisive. In this paper we will concentrate on the revenue side, e.g. on the taxes as well as on the social security contributions. Adam Smith had already formulated some very simple tax norms which have been transformed in modern tax theory. The equivalence as well as the ability-topay principle are basic yardsticks for every tax system in a democratic oriented market system, not to forget tax fairness. In the historical development process equity-oriented measures have often produced an enormous complexity of the single taxes as well as of the whole tax system. Therefore, reconsidering the Smithian principles of simplicity and of minimum compliance costs for the tax payer would even press many Western European tax systems to undergo serious reform processes which often are delayed because of intense interest group influence. Hence, a modern tax system is a simple one which consists only of a few single taxes which are easy to administer. Such a system consists of two main taxes, the income and the value added tax. Consequently in all countries of transition both taxes have been implemented, while the implementation was fostered by the fact that both also constitute the typical components of the EU member states systems. Therefore such a harmonising tax reform is the most important prerequisite to become a membership candidate. Bulgaria also tried to follow this general pattern in reforming the income tax system starting in 1992 and replacing the old socialistic turnover tax and excise duty system by the value added tax (VAT) in 1994. Especially with regard to the income tax system the demand for simplicity has not been met yet. Complex rules to define the tax base as well as a steeply progressive tax schedule have led to behavioral adaptations which are even strengthened by the effects of a high social contribution burden which is predominantly laid on the employers. In the following some concise descriptions of the tax and social contribution system are given; the paper closes with a summary, in which the impacts of the system are evaluated and some political recommendations for further reforms are presented.
Thoroughly revised and updated, this third edition offers a comprehensive and up-to-date overview of the social psychology of aggression, covering all the relevant major theories, individual differences, situational factors, and applied contexts. Understanding the causes, forms, and consequences of aggression and violence is critical for dealing with these harmful forms of social behavior. Addressing a range of sub-topics, the firstpart deals with the definition and measurement of aggression, presents major theories, examines the development of aggression and discusses individual and gender differences in aggressive behaviour. It covers the role of situational factors in eliciting aggression and the impact of exposure to violence in the media. The second part examines specific forms and manifestations of aggression, including chapters on aggression in everyday contexts and in the family, sexual aggression, intergroup aggression, and terrorism. The new edition also includes additional coverage of gender differences, gun violence, and terrorism, to reflect the latest research developments in the field. Alsodiscussing strategies for reducing and preventing aggression, this bookis essential reading for students and researchers in psychology and related disciplines, as well as practitioners andpolicy makers.
The route to chaos for a two-dimensional externally driven flow : [to appear in Physical Review E]
(1998)
Between 2002 and 2006 the Colombian government of Álvaro Uribe counted with great international support to hand a demobilization process of right-wing paramilitary groups, along with the implementation of transitional justice policies such as penal prosecutions and the creation of a National Commission for Reparation and Reconciliation (NCRR) to address justice, truth and reparation for victims of paramilitary violence. The demobilization process began when in 2002 the United Self Defence Forces of Colombia (Autodefensas Unidas de Colombia, AUC) agreed to participate in a government-sponsored demobilization process. Paramilitary groups were responsible for the vast majority of human rights violations for a period of over 30 years. The government designed a special legal framework that envisaged great leniency for paramilitaries who committed serious crimes and reparations for victims of paramilitary violence. More than 30,000 paramilitaries have demobilized under this process between January 2003 and August 2006. Law 975, also known as the “Justice and Peace Law”, and Decree 128 have served as the legal framework for the demobilization and prosecutions of paramilitaries. It has offered the prospect of reduced sentences to demobilized paramilitaries who committed crimes against humanity in exchange for full confessions of crimes, restitution for illegally obtained assets, the release of child soldiers, the release of kidnapped victims and has also provided reparations for victims of paramilitary violence. The Colombian demobilization process presents an atypical case of transitional justice. Many observers have even questioned whether Colombia can be considered a case of transitional justice. Transitional justice measures are often taken up after the change of an authoritarian regime or at a post-conflict stage. However, the particularity of the Colombian case is that transitional justice policies were introduced while the conflict still raged. In this sense, the Colombian case expresses one of the key elements to be addressed which is the tension between offering incentives to perpetrators to disarm and demobilize to prevent future crimes and providing an adequate response to the human rights violations perpetrated throughout the course of an internal conflict. In particular, disarmament, demobilization and reintegration processes require a fine balance between the immunity guarantees offered to ex-combatants and the sought of accountability for their crimes. International law provides the legal framework defining the rights to justice, truth and reparations for victims and the corresponding obligations of the State, but the peace negotiations and conflicted political structures do not always allow for the fulfillment of those rights. Thus, the aim of this article is to analyze what kind of transition may be occurring in Colombia by focusing on the role that transitional justice mechanisms may play in political negotiations between the Colombian government and paramilitary groups. In particular, it seeks to address to what extent such processes contribute to or hinder the achievement of the balance between peacebuilding and accountability, and thus facilitate a real transitional process.
The Right to Research
(2023)
Refugees and displaced people rarely figure as historical actors, and almost never as historical narrators. We often assume a person residing in a refugee camp, lacking funding, training, social networks, and other material resources that enable the research and writing of academic history, cannot be a historian because a historian cannot be a person residing in a refugee camp.
The Right to Research disrupts this tautology by featuring nine works by refugee and host-community researchers from across Africa, Europe, and the Middle East. Identifying the intrinsic challenges of making space for diverse voices within a research framework and infrastructure that is inherently unequal, this edited volume offers a critical reflection on what history means, who narrates it, and what happens when those long excluded from authorship bring their knowledge and perspectives to bear. Chapters address topics such as education in Kakuma Refugee Camp, the political power of hip-hop in Rwanda, women migrants to Yemen, and the development of photojournalism in Kurdistan.
Exploring what it means to become a researcher, The Right to Research understands historical scholarship as an ongoing conversation - one in which we all have a right to participate.
Of Rawls's two principles of justice only the second has received attention from economists. The second principle is concerned with the social and economic conditions in a just society. The first principle, however, has largely been neglected. It claims, that all people in society should have equal basic liberties. In this paper Rawls's first principle is characterised in a freedom of choice framework. The analysis reveals conceptual problems of the Rawlsian approach to justice.
This master’s thesis examined the internet content regulation in Germany from a perspective of Public-Private Partnerships. In the European Union, there has been a latest trend of initiatives aiming for combating illegal content online under the self-regulatory regime. Yet, concerns of this trend were that transparency cannot be ensured properly to safeguard the freedom of expression, and that the private intermediaries are not able to carry out effective regulation under the non-binding regulatory process. Due to these issues, Germany has legislated the Network Enforcement Act in 2017. This thesis used Mixed Methods within a Case Study Research, in order to identify the PPP type of the NetzDG, and to understand its link on transparency and effectiveness, as well as the relationship of these two dimensions. By taking an Exploratory Sequential Design, the German internet content regulation under the NetzDG was explored to understand its co-regulatory regime and to develop an instrument to measure the aspects of transparency and effectiveness. Then, the three big social media platforms, YouTube, Twitter, and Facebook, were examined according to the developed indicators. This thesis concluded as follow: First, the enactment of the NetzDG brought the shift of the regulatory paradigm from the self-regulatory to the co-regulatory. Yet, the actor-inclusive institutional arrangement of the NetzDG did not successfully result in the actual inclusion of actors in decision-making, but only improved the result transparency in the disclosure of take-down actions. Second, the level of effective regulation was not consistent across the three social media platforms under this regime. Despite these limitations, this study showed that the transparency and the effectiveness of the social media platforms’ implementation gradually improved together, instead of having a negative correlation to one another.
The power of opposition
(2022)
Proposing a novel way to look at the consolidation of democratic regimes, this book presents important theoretical and empirical contributions to the study of democratic consolidation, legislative organization, and public opinion.
Theoretically, Simone Wegmann brings legislatures into focus as the main body representing both winners and losers of democratic elections. Empirically, Wegmann shows that the degree of policy-making power of opposition players varies considerably between countries. Using survey data from the CSES, the ESS, and the LAPOP and systematically analyzing more than 50 legislatures across the world and the specific rights they grant to opposition players during the policy-making process, Wegmann demonstrates that neglecting the curial role of the legislature in a democratic setting can only lead to an incomplete assessment of the importance of institutions for democratic consolidation.
The Power of Opposition will be of great interest to scholars of comparative politics, especially those working on questions related to legislative organization, democratic consolidation, and/or public opinion.

An idealized image of European concert-goers has long prevailed in historical overviews of the nineteenth and twentieth centuries. This act of listening was considered to be an invisible and amorphous phenomenon, a naturally given mode of perception. This narrative influenced the conditions of listening from the selection of repertoire to the construction of concert halls and programmes. However, as listening moved from the concert hall to the opera house, street music, and jazz venues, new and visceral listening traditions evolved. In turn, the art of listening was shaped by phenomena of the modern era including media innovation and commercialization.
This Handbook asks whether, how, and why practices of music listening changed as the audience moved from pleasure gardens and concert venues in the eighteenth century to living rooms in the twentieth century, and mobile devices in the twenty-first. Through these questions, chapters enable a differently conceived history of listening and offer an agenda for future research.

This paper presents in the first section a methodological introduction concerning statistics of consumer prices in Georgia. The second section gives a general idea of the development of consumer prices from January 1994 till September 1999. A detailed regional analysis is added in section 3. The fourth section analyses the development of consumer prices for the eight main groups included in the total CPI. Section 5 compares the changes in Georgian CPI with the movements of foreign exchange rates in Georgian Lari. This paper ends with a summary including a short outlook to the next years.
The Jewish population of early modern Italy was characterised by its inner diversity, which found its expression in the coexistence of various linguistic, cultural and liturgical traditions, as well as social and economic patterns. The contributions in this volume aim to explore crucial questions concerning the self-perception and identity of early modern Italian Jews from new perspectives and angles.
Program behavior that relies on contextual information, such as physical location or network accessibility, is common in today's applications, yet its representation is not sufficiently supported by programming languages. With context-oriented programming (COP), such context-dependent behavioral variations can be explicitly modularized and dynamically activated. In general, COP could be used to manage any context-specific behavior. However, its contemporary realizations limit the control of dynamic adaptation. This, in turn, limits the interaction of COP's adaptation mechanisms with widely used architectures, such as event-based, mobile, and distributed programming. The JCop programming language extends Java with language constructs for context-oriented programming and additionally provides a domain-specific aspect language for declarative control over runtime adaptations. As a result, these redesigned implementations are more concise and better modularized than their counterparts using plain COP. JCop's main features have been described in our previous publications. However, a complete language specification has not been presented so far. This report presents the entire JCop language including the syntax and semantics of its new language constructs.
This book provides a new perspective on prosodically marked declaratives, wh-exclamatives, and discourse particles in the Madrid variety of Spanish. It argues that some marked forms differ from unmarked forms in that they encode modal evaluations of the at-issue meaning. Two epistemic evaluations that can be shown to be encoded by intonation in Spanish are obviousness and mirativity, which present the at-issue meaning as expected and unexpected, respectively. An empirical investigation via a production experiment finds that they are associated with distinct intonational features under constant focus scope, with stances of (dis)agreement showing an impact on obvious declaratives. Wh-exclamatives are found not to differ significantly in intonational marking from neutral declaratives, showing that they need not be miratives. Moreover, we find that intonational marking on different discourse particles in natural dialogue correlates with their meaning contribution without being fully determined by it. In part, these findings quantitatively confirm previous qualitative findings on the meaning of intonational configurations in Madrid Spanish. But they also add new insights on the role intonation plays in the negotiation of commitments and expectations between interlocutors.
This volume discusses the impact of human rights law on other fields of international law. Does international human rights law modify other fields of international law? Contributions focus on possible spillover effects of human rights on international economic or international criminal law. Does international human rights law have a streamlining effect on international law as a whole? This might be identified as a process of constitutionalisation. In this book, human rights can be understood as one of the core principles of international legal order and thus have an effect on the general law of treaties or on the settlement of disputes.
Although human rights law is a relatively young field of international law, its content and core values today are of major importance for the interpretation of international law as a whole. As we witness a redefinition of sovereignty as a responsibility of states towards the people and a shift to greater relevance of the individual in international law in general, it is a logical consequence that human rights have an impact on other areas of international law.
The in-memory revolution
(2015)
This book describes the next generation of business applications enabled by SAP's in-memory database, SAP HANA. In particular, the authors show the substantial changes introduced in S4/HANA by switching to SAP HANA. Using numerous examples and use cases from the authors' wealth of real-world experience, it illustrates the quantum leap in performance made possible by the new technology. The book is written by two of the most prominent actors in the area of business application systems: Hasso Plattner, co-founder of SAP and inaugurator of the Hasso Plattner Institute at the University of Potsdam, and Bernd Leukert, member of the Executive Board and the Global Managing Board of SAP. This clearly structured, highly illustrated book takes an exciting new technology and presents the practicality and success of first mover applications.
This paper reviews theoretical and empirical evidence of asset price movements impact on the real economic activity. A key channel is the wealth effect on consumption. Fluctuations in stock prices and housing prices influence the households wealth and could have important impacts on households consumption. In addition, stock prices may affect corporate sector investments and property prices may affect building activity. Here, the method of cointegration is used to estimate the wealth effect and the investment effect in aggregate time series for Germany after the Reunification in 1990. Moreover, we discuss the role of asset prices in the monetary policy strategy of the ECB.
The ill-posed inversion of multiwavelength lidar data by a hybrid method of variable projection
(1999)
In ihren Beiträgen verbinden die Autoren grundsätzliche philosophische Überlegungen zur grundlegenden Bedeutung von Menschenwürde für die Menschenrechte mit konkreteren Forderungen, wie mit der Befriedigung lebensnotwendiger Bedürfnisse umzugehen und was zur Beendigung von Armut notwendig ist. Ihre rechtlichen und politischen Argumente stützen sich auf jüngere Rechtsprechung regionaler Gerichtshöfe und internationaler Menschenrechtsorgane. Sie berufen sich auf die Verpflichtungsdimensionen der Menschenrechte und fragen nach der Verantwortlichkeit für deren Umsetzung. Die Autorinnen kommen aus Universitäten in Deutschland, der Schweiz, den Niederlanden und dem Vereinigten Königreich.
The homotopy classification and the index of boundary value problems for general elliptic operators

West of Potsdam’s city center lies the Golm Campus, the largest campus of the University of Potsdam. Its different buildings tell of the numerous institutions that were established at this site over the years: From the mid-1930s, the Walther Wever Barracks were located here. From 1943, it housed the Air Intelligence Division of the German Airforce Supreme Commander. In 1951, a training institution of the Ministry of State Security moved in, which existed until 1989 under different names. In July 1991, the newly founded University of Potsdam took over the premises, which are now part of the Potsdam-Golm Science Park.
The book takes you on a historic journey of the place and invites you to take a walk across today’s campus. The book includes over 110 photos and a detailed map.
