The overall aim of this thesis is to investigate the potential role of regional inter-governmental organisations (RIGOs) in international criminal accountability, specifically through the establishment of criminal accountability mechanisms, and to make a case for RIGOs’ active involvement. The thesis proceeds from the assumption that international criminal justice is a cosmopolitan project that demands that a tenable conception of state sovereignty guarantees humanity’s fundamental values, specifically human dignity. Since cosmopolitanism emphasises the equality and unity of the human family, guaranteeing the dignity and humanity of the human family is therefore a common interest of humanity rather than a parochial endeavour. Accountability for international crimes is one way through which human dignity can be validated and reaffirmed where such dignity has been grossly and systematically assaulted. Therefore, while accountability for international crimes is primarily the obligation of individual sovereign states, this responsibility is ultimately residually one of humanity as a whole, exercisable through collective action. As such, the thesis advances the argument that states as collective representations of humanity have a responsibility to assist in ensuring accountability for international crimes where an individual state is either genuinely unable or unwilling by itself to do so. The thesis therefore addresses the question as to whether RIGOs, as collective representations of states and their peoples, can establish international criminal accountability mechanisms. Relying on cosmopolitanism as a theoretical underpinning, the thesis examines the exercise of what can be considered as elements of sovereign authority by RIGOs in pursuit of the cosmopolitan objective of accountability for international crimes. In so doing, the thesis interrogates whether there is a basis in international law for such engagement, and examines how such engagement can practically be undertaken, using two case studies of the European Union and the Kosovo Specialist Chambers and Specialist Prosecutor’s Office, and the African Union and the (proposed) Hybrid Court for South Sudan. The thesis concludes that general international law does not preclude RIGOs from exercising elements of sovereign authority necessary for the establishment of international criminal accountability mechanisms, and that specific legal authority to engage in this regard can then be determined by reference to the doctrine of attributed/conferred powers and the doctrine of implied powers in interpreting the legal instruments of RIGOs. Based on this conclusion, the thesis makes a normative case for an active role for RIGOs in the establishment of international criminal accountability mechanisms, and provides a practical step-by-step guide on possible legal approaches for the establishment of such mechanisms by RIGOs, as well as guidance on possible design models for these mechanisms.

Flexibility has risen as a potential solution and complement for system operators’ current and future problems (e.g., congestion, voltage) caused by integrating distributed renewable resources (e.g., wind, solar) and electric vehicles. In parallel, local flexibility markets (LFM) emerge as a possible smart grid solution to bridge between flexibility-seeking customers and flexibility-offering customers in localized areas. Nevertheless, there is no unique, standard, or simple solution to tackle all the problems system operators and other energy actors face. Therefore, many local flexibility market concepts, initiatives (projects), and companies have developed various solutions over the last few years. At the same time, they increased the complexity of the topic. Thus, this research paper aims to describe several local flexibility market concepts, initiatives (projects), and companies in Europe. To do so, we propose a taxonomy derived from LFMs descriptions. We use the taxonomy-building research method proposed by [1] to develop our taxonomy. Moreover, we use the smart grid architecture model (SGAM) as a structural and foundation guideline. Given the numerous and diverse LFM solutions, we delimit the taxonomy by considering solutions focused on congestion management on medium and low voltage (meta-characteristic). [less ▲]

The energy transition into a modern power system requires energy flexibility. Demand Response (DR) is one promising option for providing this flexibility. With the highest share of final energy consumption, the industry has the potential to offer DR and contribute to the energy transition by adjusting its energy demand. This paper proposes a mathematical optimization model that uses a generic data model for flexibility description. The optimization model supports industrial companies to select when (i.e., at which time), where (i.e., in which market), and how (i.e., the schedule) they should market their flexibility potential to optimize profit. We evaluate the optimization model under several synthetic use cases developed upon the learnings over several workshops and bilateral discussions with industrial partners from the paper and aluminum industry. The results of the optimization model evaluation suggest the model can fulfill its purpose under different use cases even with complex use cases such as various loads and storages. However, the optimization model computation time grows as the complexity of use cases grows. [less ▲]

Im Jahr 1789 hat Luxemburg als selbstständiger und unabhängiger Staat noch nicht existiert. Es bedurfte des Wiener Kongresses (1815) und der belgischen Revolution (1830), um aus Luxemburg ein souveräner Staat werden zu lassen. Bürgerliche Freiheiten wurden den Luxemburgern allerdings erst unter König-Großherzog Wilhelm II zugestanden. Mit dem Versammlungsrecht wurde der Bevölkerung auch das Vereinigungsrecht gewährt. Das Jahr 1848 bedeutet den Startpunkt und eine erste Wegmarke im Werden der Laienmusik im Großherzogtum. Im Jahr 1940 kam es mit der deutschen Besetzung zu einem abrupten Bruch einer Freiheit, die den Luxemburgern in fast einem Jahrhundert in Fleisch und Blut übergegangen zu sein schien. Der Neubeginn ab dem Jahr 1944 bedeutete eine weitere Wegmarke im Sinne von kultureller Betätigung in einer freiheitlichen Grundordnung. Im Diskurs um weitere Wegmarken sind keine politische, sondern eher soziale, pädagogische und technologische Umwälzungen ins Visier zu nehmen. [less ▲]

The European Supervisory Authorities (ESAs) are empowered, by their founding regulations, to adopt guidelines and recommendations “with a view to establishing consistent, efficient and effective supervisory practices within the ESFS, and to ensuring the common, uniform and consistent application of Union law”. These acts can be considered genuine EU soft law since they lack the binding legal force. However, they remain perfectly non-binding only at the EU level and in the relation between the ESAs and the national competent authorities (NCAs). Although the NCAs have a duty “to make every effort to comply” with such soft law, they keep a certain leeway to decide whether they eventually comply or not. Nonetheless, the situation is different in case of financial institutions under their supervision. Formally, the EU regulations attribute to them also only a duty “to make every effort to comply”. However, once the NCA decides to comply and effectively enforces the compliance from financial institutions, the latter have a very limited, or even no leeway to decide about the compliance. Within the complex regulatory system, the NCA metamorphosis from a normtaker into an effective norm-enforcer who is capable to determine what effects the ESA soft law have at the national level. This paper focuses on the life of ESA soft law in the Czech Republic. It examines the role and power of the Czech NCA (the Czech National Bank, CNB) in the light of the legislative framework and other domestic binding legal rules. It takes into consideration the real enforcement strategy and practices of the CNB to show that, in the hands of the CNB, ESA guidelines and recommendations become acts, which produce binding legal effects upon financial institutions. Based on this observation, the paper raises questions about the proper control of ESA soft law and potential remedies. [less ▲]

Why does one need creativity? On a personal level, improvisation with available resources is needed for online coping with unforeseen environmental stimuli when existing knowledge and apparent action strategies do not work. On a cultural level, the exploitation of existing cultural means and norms for the deliberate production of novel and valuable artifacts is a basis for cultural and technological development and extension of human action possibilities across various domains. It is less clear, however, how creativity develops and how exactly one arrives at generating new action possibilities and producing multiple alternative action strategies using familiar objects. In this theoretical paper, we first consider existing accounts of the creative process in the Alternative Uses Task and then present an alternative interpretation, drawing on sociocultural views and an embodied cognition approach. We explore similarities between the psychological processes underlying the generation of new uses in the Alternative Uses Task and children’s pretend play. We discuss possible cognitive mechanisms and speculate how the generation of new action possibilities for common objects in pretend play can be related to adults’ ability to generate new action strategies associated with object use. Implications for creativity development in humans and embodied artificial agents are discussed. [less ▲]

Public History and history didactics are two subdisciplines of history that focus on reaching the world outside the academy. Both put an emphasis on “practising” history while at the same time grounding practice on theoretical reflection and empirical research with the ultimate goal of developing the most effective strategies of reaching diverse audiences to enhance historical knowledge and understanding. This roundtable explores what we mean by international public history and by the internationalization of history didactics, drawing on initiatives such as The Italian Public History Manifesto (2016) issued by the Italian Association of Public History (Associazione Italiana di Public History (AIPH). Our discussion will revolve around questions such as How must we re-shape history didactics and public history so that we take full account of transnational, diasporic and other identities based on class, gender, race, ethnicity, religion, sexuality, or ability? How can we enhance knowledge building globally by embracing different local experiences and perceptions? How do we address imbalances and the traditional North American and European centredness of our subdisciplines? [less ▲]

To adjust for the non-uniform spatiotemporal nature of traffic patterns, next-generation high throughput satellite (HTS) systems can benefit from recent technological advancements in the space-segment in order to dynamically design traffic-adaptive beam layout plans (ABLPs). In this work, we propose a framework for dynamic beamforming (DBF) optimization and adaptation in dynamic environments. Given realistic traffic patterns and a limited power budget, we propose a feasible DBF operation for a geostationary multibeam HTS network. The goal is to minimize the mismatch between the traffic demand and the offered capacity under practical constraints. These constraints are dictated by the traffic-aware design requirements, the on-board antenna system limitations, and the signaling considerations in the K-band. Noting that the ABLP is agnostic about the inherent inter-beam interference (IBI), we construct an interference simulation environment using irregularly shaped beams for a large-scale multibeam HTS system. To cope with IBI, the combination of on-board DBF and on-ground precoding is considered. For precoded and non-precoded HTS configurations, the proposed design shows better traffic-matching capabilities in comparison to a regular beam layout plan. Lastly, we provide trade-off analyses between system-level key performance indicators for different realistic non-uniform traffic patterns. [less ▲]

Machine Learning (ML) models are inherently approximate; as a result, the predictions of an ML model can be wrong. In applications where errors can jeopardize a company's reputation, human experts often have to manually check the alarms raised by the ML models by hand, as wrong or delayed decisions can have a significant business impact. These experts often use interpretable ML tools for the verification of predictions. However, post-prediction verification is also costly. In this paper, we hypothesize that the outputs of interpretable ML tools, such as SHAP explanations, can be exploited by machine learning techniques to improve classifier performance. By doing so, the cost of the post-prediction analysis can be reduced. To confirm our intuition, we conduct several experiments where we use SHAP explanations directly as new features. In particular, by considering nine datasets, we first compare the performance of these "SHAP features" against traditional "base features" on binary classification tasks. Then, we add a second-step classifier relying on SHAP features, with the goal of reducing false-positive and false-negative results of typical classifiers. We show that SHAP explanations used as SHAP features can help to improve classification performance, especially for false-negative reduction. [less ▲]
