Show moreIn the light of the fragility of current liberal democracies, this dissertation aims to contribute to rethinking political order by reconstructing Hegel’s account in the Philosophy of Right. His theory of political order has relevance as it explores how modern freedom, i.e. liberal rights and a market, can coexist with republican self-government. The reconstruction shows how a liberal order, i.e. based on the principle of individual autonomy and an instrumental account of government, must entail a loss of freedom and social and political pathologies: citizens for instance cannot acquire stable identities in the social whole and alienate themselves from the political realm. Moreover, it works out Hegel’s alternative account of political order in which freedom depends on the interplay of the opposed dynamics of the state and society: the state institutions pursuing the good of the community as a whole, while the members of civil society pursue their own good. Finally, the dissertation shows how Hegel offers a coherent and subtle account of republican citizenship and self-government, in which self-government does not depend primarily on the influence citizens exercise on political outcomes but on their ability to identify with the good of the community as a whole.

Show moreThis dissertation explores the United Nations' comprehensive approach to managing the Israel-Arab Conflict from 1967 to 1982, presenting a shift from examining peace operations as isolated efforts to viewing them as interconnected elements of a broader peace architecture. It introduces a critical analysis of the roles played by the Office of Special Political Affairs and the Office of Chief Coordinator of Peacekeeping in the Middle East, arguing that these entities were pivotal in forming a cohesive strategy despite the static mandates of individual peace missions. The research spans six chapters, starting with a historical overview of the UN’s peacekeeping framework since 1948, setting the groundwork for understanding the conflict and the evolution of peacekeeping entities. It then delves into Inter-Operation Collaboration (IOC) and the Secretariat’s political maneuvering, highlighting the impact of significant events like the Camp David Accords and the 1982 Israeli invasion of Lebanon. These events marked a shift in focus from state-centric to Israeli-Palestinian issues, challenging the UN’s influence. The conclusion assesses the UN’s role in shaping the diplomatic and security landscape of the region, underlining the organization's contributions and limitations in fostering peace and stability amidst a complex geopolitical scenario. This research offers valuable insights into the dynamics of UN peacekeeping operations in regional conflicts. Show less

Show moreThis dissertation explores the ways in which affective responses to disabled bodies are represented and how this invites us to read these bodies aesthetically. I argue that this affective impact can be understood as an affordance, a term I use to describe how the appearance of and interaction with disabled bodies produces affective responses such as fear, wonder, or disgust. I study the relationship between representation and affective reactions through literature and other art forms. Through close readings of literary texts and works of art, this dissertation offers an alternative to so-called model thinking—an approach that emphasizes categorization. Instead, I propose a reading that focuses on how bodily capacities are culturally and socially translated into (dis)abilities. Unlike taxonomic approaches that categorize and generalize, this method allows moving from the particular to the private. Works of art, although prone to generalization, emphasize their unicity and resist categorization. By analyzing how different art forms represent disabled bodies, the dissertation brings a new dimension to understanding our emotional responses and the aesthetic appreciation of bodily diversity.

Show moreIn this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts. The investigation comprises two main perspectives: Firstly, Chapter 2 delves into their direct impact on fungal biomass input to the soil via lab experiments. Secondly, Chapters 3, 4, and 5 explore their role in mediating litter decomposition through modeling. This thesis sheds light on the significance of mycorrhizal fungi in the soil carbon cycle and underscores the necessity of accounting for their effects when analyzing global soil carbon dynamics. Additionally, the research underscores the importance of understanding mycorrhizal fungi responses to environmental changes, given their sensitivity to factors like temperature and precipitation.

Show moreSchistosomiasis is a parasitic infection caused by worms of the genus Schistosoma. It is a neglected tropical disease, affecting mainly populations living in poverty without adequate sanitation. Treatment relies on one drug mainly, praziquantel, and its efficacy is dependent on the diagnostic tool used.Due to the parasite’s intravascular localisation, it is difficult to directly quantify them in infected humans. Thus, methods of detection like worm-derived circulating cathodic antigen (CCA) in urine or circulating anodic antigen (CAA) in urine and serum, have gained more attention. This thesis aims to explore and shed light on how to interpret schistosome-related circulating antigens CCA and CAA. We have addressed the interpretation of schistosome related assays in endemic and non-endemic regions, supported by data obtained from an animal study. Different diagnostic value can be attributed to different assays within different contexts. The results highlight the importance of a better understanding of antigen excretion patterns by different species to support optimalisation of antigen-based diagnostics of schistosomiasis. Show less

Show moreVoltammetry plays a crucial role in modern scientific research by offering valuable insights into the electrochemical properties of materials, with wide-ranging applications in fields such as materials science, energy storage, corrosion studies, and sensor development.Gold, known for its exceptional inertness, provides a unique platform for studying intricate electrochemical processes due to its stability and slow electrochemical behavior. However, certain questions regarding gold voltammetry have remained unresolved throughout history. To address these gaps, our research employed a combination of electrochemical cyclic voltammetry and advanced in situ techniques like surface-enhanced Raman spectroscopy (SERS), Rotating ring-disk electrode (RRDE), and Electrochemical quartz crystal microbalance (EQCM).Through our investigations, we not only redefined the mechanism of gold oxide formation but also uncovered the reasons behind the structural reconstruction of gold oxide. Additionally, we elucidated the electrochemical interfacial structure on gold from a novel perspective focusing on charge distribution.The significance of these findings lies in their fundamental nature, with the potential to inspire researcher to reconsider interpretations of voltammetry behaviors across various materials and research fields. We anticipate that our work will stimulate further exploration and innovation in the realm of electrochemistry, paving the way for new discoveries and advancements. Show less

Show moreDespite the history of studies on methanol formation from CO2, the dominant elementary reaction steps that constitute the chemical mechanism for this catalyzed process are not determined. Two main issues may cause doubt about the current level of understanding: 1) the very large difference in the coverage-dependent sticking probabilities for CO2 and CO and unavoidable CO contamination 2) the complex oxidation of the copper surface and unavoidable build-up of a (partial) oxide layer.In this thesis, we studied the sticking probability of O2 on Cu(111) and compared results to previous experimental and theoretical results. The dissociative chemisorption of O2 on Cu(111) is a direct, activated process with a minimum barrier of approximately 100 meV.In an attempt to develop a method that may undeniably quantify the reactivity of CO2 onto clean and H-containing Cu surfaces, we investigated co-adsorbed CO and O on Cu(111) and Cu(211) with RAIRS. Cu(211) oxidizes much more readily than Cu(111). For incomplete oxidation, the system CO adsorbs to small isolated metallic Cu edges and patches. Fully oxidized Cu(211) binds CO but in a rather different form than clean metallic Cu. The vibrational frequency of adsorbed CO is changed as the co-adsorbed O coverage varies on Cu(211). Show less

Show moreContrary to common belief, sign languages are distinct across different communities and cultures, evolving organically through interactions among deaf people, rather than being based on spoken languages. Each sign language has its own grammar, vocabulary, and cultural nuances, with variations even within a single country, showcasing the diverse communication methods within the deaf community. Deaf individuals often face encouragement to use spoken language techniques like lipreading or text communication, highlighting a bias towards spoken languages. This is compounded by the lack of sign languages in linguistic technologies, emphasizing the need for more inclusive research and development. This dissertation aims to address this gap using machine and deep learning to improve sign language processing and recognition. It covers six chapters, introducing methods for video-based sign annotation, webcam-based sign language dictionary search, and ranking systems for sign suggestions. It also explores tools for visualizing and comparing sign language variation, contributing valuable resources to linguistic research. Show less

Show moreThis thesis investigates the contribution of quantum computers to machine learning, a field called Quantum Machine Learning. Quantum Machine Learning promises innovative perspectives and methods for solving complex problems in machine learning, leveraging the unique capabilities of quantum computers. These computers differ fundamentally from classical computers by exploiting certain quantum mechanical phenomena. The thesis explores various proposals within quantum machine learning, such as the application of quantum algorithms in topological data analysis. With respect to topological data analysis, results demonstrate that quantum algorithms solve problems considered inefficient in classical settings. The thesis also explores structural risk minimization in quantum machine learning models, identifying crucial design choices for new quantum machine learning models. Additionally, it introduces quantum models in reinforcement learning, which deliver comparable performance to traditional models and are superior in certain scenarios. The final part identifies learning tasks in computational learning theory where quantum learning algorithms have exponential advantages. In summary, this thesis contributes to understanding how quantum computers can address complex machine learning problems, from topological data analysis to reinforcement learning and computational learning tasks.

Show moreThe dissertation explores the relationship between online and offline anti-corruption activism in Banten, Indonesia. It examines the historical background of anti-corruption activism in Indonesia, the comparison of online discourse of corruption framed by national civil society organizations (CSOs) and local activists, the impact of online activism on citizenship characteristics, and its potential transformation into strong or weak offline mobilization. The study uses social media ethnography to examine the materiality of being online and its relation to corruption and anti-corruption campaigns. The research reveals that corruption is primarily constructed as a legal discourse in national anti-corruption campaigns, while in Banten, morality and religious discourse are used to frame corruption. Online anti-corruption activism in Banten involves digital acts of reporting and sharing corruption news and flaming to resist corrupt leaders. This approach has led to the development of 'digital affective citizenship', where citizens express anger, hate, passion, and disgust towards corrupt leaders. The dissertation also discusses the characteristic of citizens in Banten that reflects "powerless angry citizens," who desire to influence political outcomes through corruption but feel powerless due to the mismatch between their desire and the limitations of participatory channels and organizations.

Show moreChinese materia medica (CMM), comprising a diverse array of natural substances from plants, animals, and minerals, has been integral to Traditional Chinese Medicine (TCM) throughout history. This study investigates the dynamic evolution of CMM, noting shifts in species for improved therapeutic effects and the abandonment of those with adverse outcomes. By examining historical CMM specimens, particularly those in Dutch collections, tangible evidence of this evolution emerges.The Westhoff collection, spanning 140 years, reveals significant changes alongside enduring practices. A handwritten catalogue accompanying the collection aligns with modern CMM practices, indicating a remarkable continuity. Comparative analyses of historical collections and contemporary CMM in EU markets over three centuries emphasize the stability of core medicinal plant taxa. Additionally, the study validates the delayed luminescence (DL) technique for discerning CMM storage times, showing promising results.Despite challenges in preservation, historical CMM specimens offer unique insights into medicine's history, underscoring their importance for further research and understanding.

Show moreRadiotherapy is intriguing as it not only eliminates tumor cells but also triggers a response from cytotoxic T cells, which attack the tumor. Thus, radiotherapy and immunotherapy are being combined in clinical studies, although their success has been limited. We used mouse tumor models to understand how radiotherapy induces T cell priming and subsequent anti-tumor immunity. In a model resembling lymphocyte-depleted cancer, we identified obstacles to systemic radiotherapy-induced T cell responses and proposed interventions to overcome them. Additionally, we explored strategies to counter local T cell suppression in the tumor microenvironment. In poorly immunogenic tumors, radiotherapy can provoke a T cell response, but this is counteracted by the generation of immunosuppressive Tregs. Combining radiotherapy with checkpoint immunotherapy, despite its success in humans, unexpectedly amplified the Treg response, further hindering cytotoxic T-cell activity. Our findings suggest this immunotherapy may not benefit these cancers. We discovered that molecules like CD80 and CD86, capable of stimulating T cells via the CD28 receptor, have distinct roles in promoting cytotoxic and Treg cells. Blocking CD86 enhanced cytotoxic T cell responses post-radiotherapy, leading to tumor rejection. Our study elucidates how tumor characteristics shape T-cell responses, how radiotherapy can evoke both favorable and unfavorable responses, and how targeted antibody immunotherapy can influence this interplay.

Show moreCutaneous malignancies are the most frequent human malignancy with an increasing incidence reaching epidemic proportions among Caucasians in Europe, America and Australia. The most common cutaneous malignancy is basal cell carcinoma, followed by squamous cell carcinoma (cSCC) and melanoma.(1-3) There are also other, less common cutaneous malignancies which consist of less than 5% of the cutaneous malignancies. Some of these rare cutaneous malignancies are still considered skin cancer such as sebaceous carcinoma,while others are classified as soft tissue sarcoma (DFSP, angiosarcoma). In this thesis, I aimed to analyse outcome after surgical procedures for rare cutaneous malignancies and the rare locally advanced cases of cSCC. Show less

Show moreThis thesis introduces the concept of "physics-based inverse design", working on the notion that the physical driving forces governing functionality are inherently encoded in independently parameterized energy functions, which can be resolved through the use of inverse design strategies.The thesis describes the development of EVO-MD, a Python-based implementation of the physics-based inverse design concept. EVO-MD is capable of automatically setting-up, performing, and analyzing molecular dynamics simulations, allowing for the evolutionary optimization of complex and dynamic features in peptides. Examples of such applications include the optimization of lipid composition and curvature sensors, and the development of peptides with antiviral properties. Show less

Show moreThe early history and development of the historiographical method and theory of “conceptual history” resp. “Historical Semantics”—the latter being the overarching term that includes the specifically German version of conceptual history (= Begriffsgeschichte)—is still widely unknown. One of the first central protagonists of the beginnings of this now widely appraised historiographical approach was the German-Jewish historian Richard Koebner (1885-1958). As a transnational actor, Koebner was not only part of the specifically German beginnings of Begriffsgeschichte during the Weimar Republic, but he was also—after his forced emigration to Jerusalem and during his retirement-years in London—influential for the development of Historical Semantics in Israel and England.

Show moreAcute cardiovascular syndromes, including myocardial infarction or stroke, are the principal cause of death in the Western society. The main underlying pathology of cardiovascular diseases is atherosclerosis, which is caused by the accumulation of lipids and inflammatory cells in the vessel wall, in so-called atherosclerotic plaques. Current therapies mainly target the disturbed lipid homeostasis, but recent clinical trials have shown a clear benefit in treating patients with anti-inflammatory drugs. However, more specific targeting is required to avoid unwanted side effects. In this thesis, we have generated a detailed atlas of all the cells present in human atherosclerotic plaques using a novel state-of-the-art technique called single-cell RNA sequencing. This data set can be applied as a powerful tool to select potential drug targets with a functional relevance for atherosclerosis. We showed that the majority of the immune cells in the human atherosclerotic plaque consisted of T cells. Subsequently, we identified a pro-inflammatory population of T cells that likely responds to a plaque-derived antigen, suggesting that atherosclerosis has an autoimmune-like component. Finally, we have applied our single-cell atlas to define and validate targets to intervene with the recruitment and activation of mast cells and other immune cells in atherosclerosis. Show less

It covers almost a century from 31–128/651–746. It discusses the conquests within the context of the geographical and political complexity of the region. It highlights the local political situation before the Arab Muslims’ arrival and the active role of Bactrian rulers whose cooperation and resistance shaped and reshaped the conquests. In doing so, it combines a broad spectrum of sources. It brings Bactrian, Arabic (and relevant Middle Persian and Sogdian) documents with the literary sources, specifically Arabic narratives related to the conquests and Persian and Chinese reports. It also consults numismatic data, seals and sealings, inscriptions, and archaeological reports. Based on a systematic analysis of these sources, this dissertation shows that the Arab Muslim conquests of Bactria were not simply the results of a series of ‘pre-planned’ military operations initiated and led by the Arab Muslims, as it is often assumed to have been the case. In contrast, the conquests were highly complicated as they were deeply affected by the local and regional political situation that were not considered. The local and regional political competitions in late Sasanian Khurasan pulled the Arab Muslims into the region, where they helped the local rulers to implement their political agendas. However, being in Sasanian Khurasan allowed the Arab Muslims to learn about local political competition, become part of it, create their niche of power, and eventually establish their political domination over the region. The conquests of Sasanian Khurasan, Bactria, Sogdiana and Khwarazm (that formed Umayyad Khurasan) became possible only with the help of some local rulers who viewed the Arab Muslims as powerful allies to overcome their internal or neighbouring rivals. The local rivalries benefited the Arab Muslims the most as they provided space for the expansion and consolidation of Arab Muslim authority in the region in the long term. At the same time, the Arab Muslim settlements in the region marked the beginning of a centuries-long process of Islamicisation in Bactria, out of which the Islamic Balkh has emerged. Show less
