Within this peace agreement, the Commission for the Clarification of Truth, Coexistence and Non-Repetition was created. The Commission was mandated to produce a report explaining the historical context, origins and multiple causes of the conflict. With the creation of the Commission, the dynamics of dispute of the armed conflict moved to the field of history and memory, generating a scenario of tension among the actors involved around the Commission's narratives.

A key neural marker of this process is the error negativity (Ne/ERN), a negative deflection at frontocentral electrodes shortly after an error, which reflects fast and automatic error processing. Theoretical accounts attributed the Ne/ERN to conflict monitoring and prediction error, but the exact mechanism remains unclear. In three studies, I investigated the Ne/ERN's role in error monitoring and its relationship with other error-related phenomena. Study 1 found that the Ne/ERN varies with the level of post-response conflict. Study 2 showed that conscious error detection can occur without the Ne/ERN, suggesting separate neural bases for early error processing and error awareness. Study 3 explored links between the Ne/ERN and autonomic signals, showing that error-related pupil dilation is associated with the Ne/ERN while heart rate deceleration is not. These findings clarify the functional role of early error processes as reflected by the Ne/ERN and their relationship with other aspects of error processing.}, subject = {Klinische Psychologie}, language = {en} } @phdthesis{Ebeling2025, author = {Ebeling, Fabian}, title = {Film, Skulptur, Plan: Eine Mediengeschichte der smarten Stadt 1.0}, doi = {10.17904/ku.opus-1021}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:824-opus4-10210}, school = {Katholische Universit{\"a}t Eichst{\"a}tt-Ingolstadt}, pages = {299 Seiten : Illustrationen, Karte}, year = {2025}, abstract = {Die Smart City ist seit den sp{\"a}ten 2000er-Jahren zu einem Paradigma der Stadtplanung und -entwicklung geworden.

Dual holdings and shareholder-creditor agency conflicts: Evidence from the syndicated loan market We examine implications from the expansion of private equity (PE) firms into the CLO (i.e. leveraged lending) business. Due to similarities in the investment universes of CLO managers and PE firms, asset management groups running both of them frequently hold debt and equity claims of the same company. Our results indicate lower credit costs for these companies through mitigation of shareholder-creditor agency conflicts. The lower funding costs imply increased equity returns for the sponsoring PE firms. In addition, our findings suggest that PE-affiliated CLO managers benefit from informed trading in the secondary leveraged loan market. 2. Affiliated investment bias in collateralized loan obligations Collateralized loan obligation (CLO) managers are often part of asset management groups that also operate private equity (PE) firms. This paper examines whether these CLO managers exhibit a bias towards loans to companies sponsored by their affiliated PE firms. We find that CLO managers overweight these affiliated investments in their portfolios. Purchase level analyses reveal that the positive relationship between affiliation and investment is highly concentrated in primary market trades. Evidence suggests that the affiliated investment bias is partially explained by group-level incentives to support the funding of the PE firm's portfolio companies. Moreover, preferential allocations by loan arrangers contribute to the observed bias. 3. Revisions to the Basel securitization framework and their impact on CLOs In December 2017, the European regulation on capital requirements for securitizations was comprehensively revised. This paper examines the impact of these revisions on collateralized loan obligations (CLOs). A comparison of the results of risk weight calculations for a typical CLO under the previous and revised frameworks shows an overall increase in capital requirements. The increase is particularly pronounced under the new standardized approach (SEC-SA). However, difference-in-difference analyses of credit spreads indicate no effect of the higher capital requirements on the interest rates of CLO tranches. These results suggest that the cost of regulatory capital requirements for banks is limited.}, subject = {Collateralized loan obligation}, language = {en} } @phdthesis{Cara2025, author = {Cara, Christian}, title = {Three essays on asset management and capital allocation}, doi = {10.17904/ku.opus-1013}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:824-opus4-10132}, school = {Katholische Universit{\"a}t Eichst{\"a}tt-Ingolstadt}, pages = {92 Seiten : Diagramme}, year = {2025}, abstract = {This dissertation explores key challenges and innovations in contemporary asset management through three self-contained empirical essays. Each paper examines a distinct but interrelated topic in portfolio construction, contributing to a more resilient and practically viable approach to investing. Paper 1: The Performance of Risk-Based Asset Allocation in Downward Markets - An Empirical Examination The first paper investigates the effectiveness of risk-based portfolio strategies - such as minimum variance, equal risk contribution, and risk parity - during periods of market stress. Motivated by the shortcomings of return-optimized models in crisis periods, the paper conducts an extensive backtest using a multi-asset dataset across several downturns. It finds that risk-based strategies consistently offer superior downside protection and more stable performance compared to traditional approaches. These results underscore the robustness of risk-focused allocations when facing uncertain or volatile markets. Paper 2: A Performance "Horse Race": Does Anything Beat the 1/N Portfolio? The second paper revisits the enduring puzzle of the 1/N (equal-weighted) portfolio's performance. Despite its simplicity, previous research has shown it often rivals or outperforms optimized strategies. Using an expanded dataset and robust methodology, this paper compares a wide range of portfolio construction techniques - including mean-variance optimization and shrinkage methods - against the 1/N benchmark. The findings reaffirm the strong performance of the na{\"i}ve strategy, particularly when estimation error and real-world frictions are considered. While some optimized models perform better in specific contexts, none dominate consistently. Paper 3: Index Tracking in Crisis Periods - An Empirical Investigation of the German DAX Index The third paper shifts focus to passive investment strategies, specifically the accuracy and stability of index tracking during market crises. Using the German DAX as a case study, the paper compares multiple tracking approaches - such as constrained regression and relative optimization - under both normal and crisis conditions. Results reveal that tracking performance deteriorates notably in turbulent markets, with simpler, constraint-based methods offering more consistent tracking accuracy. This highlights the limitations of passive strategies under stress and points to the need for more adaptive frameworks.}, subject = {Portfoliomanagement}, language = {en} } @phdthesis{Welters2025, author = {Welters, Nina}, title = {Hunting "the wild": (re-)configurations of "the wild" through dynamics of practices, imaginations and place}, doi = {10.17904/ku.opus-1012}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:824-opus4-10120}, school = {Katholische Universit{\"a}t Eichst{\"a}tt-Ingolstadt}, pages = {173 Seiten : Illustrationen, Karte}, year = {2025}, abstract = {Hunting is typically regarded and publicly often criticized as a rather archaic and outdated process of tracking and shooting an animal. However, it can also be understood in a more symbolic way. As a superordinate term, hunting can be referred to as a practice of going after or chasing a specific desire - be it a material object, a living being or immaterialities. One thing that has gained a special value in today´s modern(ised) world, is the experience of seemingly "original" nature and animals - often phrased under the term "the wild". More and more people can be found participating in a variety of practices of hunting "the wild", influenced by certain desires, motivations, and geographical imaginations at predestined places. While there already is a great range of research revolving around what is understood as wilderness, it is rarely discussed how these varying desires and seemingly pre-existing configurations come into practice and thereby shape the places of "the wild". Therefore, this project aims at dissecting elements of practices and imaginations revolving around "the wild" and place them in a wider context of postcolonial discussions. Furthermore, it wants to contribute to a practice-based approach to better understand desire as well as the process of succeeding at its fulfillment and its volatility. As tools, a variety of ethnographic methods like observatory participation, go-along interviews or hanging outs is used and complemented by semi-structured interviews to capture different practices and types of hunting "the wild".}, subject = {Namibia}, language = {en} } @phdthesis{Buchner2025, author = {Buchner, Lisa}, title = {From leaf traits to canopy signatures: a multiscale and multisensory assessment of ash dieback in Fraxinus excelsior L.}, doi = {10.17904/ku.opus-1015}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:824-opus4-10155}, school = {Katholische Universit{\"a}t Eichst{\"a}tt-Ingolstadt}, pages = {X, 95 Seiten : Illustrationen, Diagramme, Karten}, year = {2025}, abstract = {Ash dieback, a disease caused by the fungal pathogen Hymenoscyphus fraxineus, is severely threatening the existence of the European common ash (Fraxinus excelsior L.). The invasive pathogen leads to progressive symptoms such as leaf loss, shoot dieback, and stem necrosis, often resulting in high mortality in affected forest stands. While these visual symptoms are well documented, finer-scale physiological and morphological leaf responses remain largely unexplored. Ash dieback symptom severity is typically assessed through time-intensive field-based ratings; however, remote sensing technologies such as Unmanned Aerial Vehicles (UAVs) offer new opportunities for large-scale, remote assessment of disease impact. Therefore, this dissertation applies a multiscale and multisensory approach to assess the effects of ash dieback. The main research questions were: (1) Does ash dieback, beyond visible symptoms such as leaf loss and shoot dieback, also induce fine-scale morphological and physiological alterations in the leaves of infected ash trees? (2) Can multisensory UAV data and the thereof calculated vegetation indices detect different degrees of damage caused by ash dieback? (3) What level of segmentation accuracy is required to ensure reliable estimation of mean vege-tation index values for individual ash tree crowns? Field investigations were carried out at four study sites in 2022 and 2023, combining visual vitality assessments with detailed analyses of leaf physiology and morphology in ash trees affected by ash dieback. The examined leaf traits included chlorophyll fluorescence, chlorophyll content, Specific Leaf Area (SLA), leaf thickness, and Fluctuating Asymmetry (FA), all of which were evaluated in relation to visually assessed damage severity. In addition, at two of the sites, repeated UAV-based aerial surveys were conducted from May to October over two consecutive years to capture the whole vegetation period of the common ash, using RGB, multispectral and thermal sensors. Complementing this, close-range multispectral images of individual tree crowns were acquired in 2023 to provide higher spatial resolution data for detailed crown analysis. In Publication 1 of this dissertation, physiological and morphological leaf traits were investigated in relation to visually assessed disease severity. Among the measured traits, SLA exhibited the most consistent and significant correlation with increasing damage severity, highlighting a potential link between leaf morphology and ash dieback. In Publication 2 a novel UAV-based monitoring workflow that utilizes RGB and multispectral imagery is introduced to classify ash dieback severity via vegetation index thresholds. The study demonstrated that both RGB and multispectral indices, particularly the Green-Red Vegetation Index (GRVI) and Difference Vegetation Index (DVI), can effectively distinguish between mildly and severely damaged trees. The combination of both multispectral and RGB indices achieved a combined classification accuracy of 77.2 \%. Publication 3 explored the influence of ash tree crown segmentation precision on vegetation index reliability. A newly developed fine segmentation method, based on unsupervised machine learning, successfully excluded non-foliar elements such as ground pixels and canopy gaps, improving spectral data interpretation. Although mean vegetation index values per crown did not differ significantly between coarse and fine segmentation, vegetation index heterogeneity increased with disease severity, emphasizing the added value of detailed crown delineation for detecting subtle stress patterns. Collectively, these studies contribute a scalable and interdisciplinary framework that bridges leaf-level physiological and morphological measurements with crown-level spectral data and machine learning-based crown segmentation. They further demonstrate how UAV-based remote sensing can be effectively integrated into long-term conservation strategies for Fraxinus excelsior L. This work underscores the importance of combining plant physiology, remote sensing, and machine learning to advance forest health monitoring and offers practical insights for the conservation of Fraxinus excelsior L. under ongoing disease pressure.}, subject = {Eschen}, language = {en} } @phdthesis{Grunenberg2025, author = {Grunenberg, Martina}, title = {Zwischenmenschliche Konflikte}, doi = {10.17904/ku.opus-1004}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:824-opus4-10046}, school = {Katholische Universit{\"a}t Eichst{\"a}tt-Ingolstadt}, pages = {V, 191 Seiten : Illustrationen, Diagramme}, year = {2025}, abstract = {Konflikte entstehen oftmals, wenn eine Person das Verhalten einer anderen als Verletzung pers{\"o}nlicher oder sozialer Normen, als Vertrauensbruch oder als Ungerechtigkeit wahrnimmt.

Die vorliegende Dissertation untersucht daher ausgew{\"a}hlte personale und situationale Einflussfaktoren auf diese individuellen Reaktionen. Diese Faktoren werden in vier Publikationen aus unterschiedlichen Perspektiven beleuchtet, um spezifische Ansatzpunkte zur Pr{\"a}vention und Deeskalation von Konflikten zu identifizieren.

Es zeigt sich, dass Personen mit starken Macht- und Gerechtigkeitsmotiven eher zu {\"u}berproportionalen Racheformen neigen. Zudem bevorzugen gerechtigkeitsorientierte Personen eine indirekte Bestrafung durch Dritte oder das Schicksal gegen{\"u}ber einem g{\"a}nzlichen Racheverzicht.

As UYRs are usually placed in residential group homes in the Child and Youth Welfare System (CYWS) in Germany, it is important to analyze the role of the institutional environment on UYR's mental health, as well as the symptom recognition and agreement with their caregivers concerning the symptomatology and how psychotherapeutic treatment can be facilitated. This dissertation synthesizes findings from three publications examining these research questions. The first publication found that lower caregiver workload predicted reduced PTSS, depression, and anxiety, while UYR-specific accommodation was linked to lower PTSS after one year. Additionally, open group climate, defined as a supportive, warm, responsive, and respectful atmosphere, mediated the effect between physical facility characteristics (accommodation quality) and PTSS, depression, and anxiety, as well as between living in a UYR-specific group and PTSS and depression. The second publication showed low but statistically significant agreement between self- and caregiver reports, with self-reports consistently yielding higher scores regarding PTSS. Greater disagreement was associated with comorbid symptoms and shorter facility stays. The third publication qualitatively identified structured training programs, supportive caregivers and facilities, and skilled interpreters as key facilitators for psychotherapeutic treatment of UYRs from the perspective of psychotherapists. Overall, this dissertation underscores the necessity of specialization across all fields. This includes trauma-informed care in UYRs-specific groups, widespread mental health screenings, training for caregivers and interpreters, and adequate staffing to ensure symptom recognition and service accessibility. Strengthening local partnerships between CYWS facilities and psychotherapists, along with implementing outreach approaches, can enhance access to mental health care. Policymakers must uphold facility standards, invest in staff resources, and support financial measures for interpreters and evidence-based interventions.}, subject = {Jugendlicher Fl{\"u}chtling}, language = {en} } @phdthesis{Mondorf2025, author = {Mondorf, Bastian}, title = {Gerechtigkeit als Tugend im Kontext von Coaching und Beratung}, doi = {10.17904/ku.opus-1001}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:824-opus4-10011}, school = {Katholische Universit{\"a}t Eichst{\"a}tt-Ingolstadt}, pages = {217 Seiten}, year = {2025}, abstract = {Die Arbeit befasst sich mit dem Ansinnen, verschiedene Facetten von Gerechtigkeit zu betrachten und Konzeptionen von Gerechtigkeit sowie die daraus erfolgenden Ableitungen zu illuminieren.
