Data for "Sampling Uncertainty of Research Topics"
(2026-06) Naboka-Krell, Viktoriia
The replication package contains the data and analysis codes for the study "Sampling Uncertainty of Research Topics", which examines the measurement of sampling uncertainty in latent topic models. The dataset comprises 19,059 abstracts submitted to the European Research Consortium for Informatics and Mathematics (ERCIM) and Computational and Financial Econometrics (CFE) conferences between 2007 and 2023. The abstracts have an average length of 158 words (including title) and underwent standardized preprocessing: After removing special characters, numbers, and stopwords, as well as lemmatization (using spaCy with the en_core_web_lg model), a vocabulary of 1,844 unique words remained. **Contents of the ZIP Files** *Data_Simulations.zip* Contains the raw data, processed datasets, and all analysis results relevant to the main study. This includes: - The original abstracts (before and after preprocessing), - The generated bootstrap corpora (for resampling analyses), - The estimated topic models (including document-specific topic weights), - The computed model fit metrics (e.g., sBIC for determining the optimal number of topics), - The Python and R code for data preprocessing, model estimation (including Structural Topic Modeling), and bootstrap analysis, - The results for Figures 1–5 and Tables 1–2 of the paper (e.g., sBIC trends, topic weights, recall metrics). *Algorithm_Confidence_Bands_Word_Clouds.zip* Includes the MATLAB code for generating uncertainty-adjusted word clouds (Figure 6 in the paper). This algorithm visualizes the robustness of topic-word probabilities across bootstrap replications by generating confidence bands for the top words of each topic. *Algorithm_Counts_Top_Flop.zip* Contains the MATLAB code for calculating the top and flop words for selected topics (basis for Figure 7). The code identifies the most and least stable words within a topic across all bootstrap samples, enabling a qualitative assessment of topic stability. *Algorithm_Topic_Time_Series.zip* Includes the code for generating the topic time series (basis for Figure 8). This algorithm aggregates document-specific topic weights on an annual basis and computes confidence bands for the temporal evolution of topic prevalence.

Transpositionsoperationen bei Okulomotoriusparese
(2026) Okcu, Arda
Ziel dieser Arbeit war es, die Effektivität und Sicherheit einer modifizierten Technik der nasalen Transposition des gesplitteten M. rectus lateralis (NTSLR) mit temporärem Absetzen und anteriorer Refixation der Mm. obliqui superior und inferior bei Okulomotoriusparalyse zu untersuchen. Retrospektiv wurden 16 Augen von 15 Patienten mit chronischer Okulomotoriusparese ausgewertet. Die prä- und postoperative Diagnostik umfasste Schielwinkelmessungen, Visus- und Refraktionsbestimmung sowie eine regelmäßige OCT-Diagnostik zur Erfassung möglicher chorioretinaler Komplikationen. Die durch die äquatornahe Transponatfixation und temporäre Desinsertion der Mm. obliqui modifizierte NTSLR-Technik führte zu einer stabilen Reduktion der Exotropie von im Mittel 42° auf eine im Mittel nahezu orthotrope Position. Der horizontale Operationseffekt ist mit dem Effekt der ursprünglichen, von Kaufmann beschriebenen Technik und anderer, später beschriebenen Modifikationen vergleichbar. Hinsichtlich der vertikalen Deviation zeigte sich kein systematischer Operationseffekt. Eine vertikale Wirkung fiel nur in Einzelfällen auf. Die OCT-Diagnostik zeigte zu keinem Zeitpunkt eine seröse Netzhautabhebung oder andere Makulaveränderungen. Auch sonstige in der Literatur erwähnte Komplikationen traten in keinem Fall auf. Die äquatornahe Fixation der transponierten Muskelhälften und das Absetzen der schrägen Muskeln erlauben eine spannungsarme Transposition mit einer im Vergleich zur originalen Technik größeren Distanz der Muskelhälften zu den Vortexvenen, wodurch ein chorioidaler Abflussstau offenbar vermieden wird.
Stimuli for "How emotional is structural listening? A mixed-methods study on music perception and recognition"
(2026-11-02) Philipp Raatz
**Dataset contents:** This item contains the two main audio stimuli used in a music perception study: (1) a fugue and (2) a neo-classical piano piece (NCP). The audio files were produced in the digital audio workstation Cubase using the virtual piano instrument "The Grandeur." **Experimental design:** The stimuli were used in a study with a 2 (music style: fugue vs. neo-classical piano piece) × 2 (order of listening tasks: structural–emotional [SESE] vs. emotional–structural [ESES]) between-subjects design. In addition, each participant listened to the same stimulus four times, which served as the within-subject variable; the specific stimulus (fugue or NCP) was selected randomly per participant group. **Associated measures:** The item is associated with, but does not include, the following instruments, which were used in the study: pre-test questionnaires – the German version of the Arnett Inventory of Sensation Seeking (AISS; Arnett, 1994; German validation: Roth, 2003), the Music Empathizing–Music Systemizing inventory (ME-MS; Kreutz et al., 2008) and the "Musical Training" subscale of the Goldsmiths Musical Sophistication Index (Gold-MSI; Müllensiefen et al., 2014; German validation: Schaal et al., 2014) – as well as post-stimulus measures: the PANAS-KS (Positive and Negative Affect Schedule, short version) and two 7-point Likert-scale ratings of liking and experienced intensity of the stimulus. **Technical details:** File format: WAV
Pro-Environmental Behavior Change Interventions: Experimental Evidence from Socially Responsible Investment and Pro-Biodiversity Behaviour
(2026) Nieß, Sarah
Human behaviour, both individual and collective, is the central underlying cause of the multiple environmental crises that we face today. More evidence on effective and scalable interventions to promote pro-environmental behaviour (PEB) is needed to bring about urgent transformative change. However, three central impeding developments can be observed in PEB intervention research: First, most studies on PEB interventions have focused on consumer behaviours and on climate impacts, with little attention given to other behaviours and environmental impacts. Second, research into the various PEB domains in different fields has mainly been conducted in isolation, with few attempts to connect these insights. Third, intervention research often treats audiences as homogeneous, focusing on main effects while rarely exploring how effectiveness varies depending on the target group. This dissertation explores how connecting evidence across PEB domains can enhance understanding of behaviour change interventions. This question is examined by bringing together evidence from two contrasting domains that have received little attention in studies of interventions: socially responsible investment (SRI) and pro-biodiversity behaviour. Their distinctiveness makes these domains well-suited to demonstrating the wide variation of PEB. A specific intervention for behaviour change is conducted in each domain, and the results are brought together in this dissertation. Article 1 comprises a narrative literature review to identify research gaps on SRI interventions and evaluate the potential for theory-informed transferability of interventions from the consumption to the investment domain. The outcome is a list of nine supported intervention strategies and 16 additional interventions that are potentially transferable to the investment context, which can be tested in future SRI research. Article 2 is an empirical exploration of a specific research gap identified in Article 1. An experiment in the prosocial and sustainable consumption domains is conceptually replicated in the SRI domain. The study compares the effect of moral versus financial information framing under private or public visibility conditions. The results suggest that visibility moderates framing: moral framing leads to higher SRI under conditions of public visibility, but framing has no influence under private conditions. Therefore, the visibility effect identified in prosocial and sustainable consumption studies, in which financial framing was found to be more effective in private contexts and moral framing in public contexts, can be partially replicated in the SRI context for the public condition. A second experiment explores the effects of framing and visibility for different investor segments. Using latent class analysis, participants were grouped by values, SRI interest, financial literacy, and confidence. Three investor segments emerged, consistent with existing segmentation studies. The results show that the reactions in the three segments differ in terms of framing and visibility. For instance, a return-focused investor segment with low interest in SRI does not respond to framing or visibility. Article 3 shifts the focus to the second domain of this dissertation: pro-biodiversity behaviour. Here, the impact of a large-scale behaviour change intervention implemented by the German newspaper Die Zeit is evaluated. The intervention aimed to promote insect-friendly attitudes and behaviours. The analysis incorporates pre-intervention levels of several insect-related outcome variables to determine the heterogeneity in intervention effectiveness across participants. The results suggest that the intervention successfully increased insect-friendly behaviour. However, insect-related attitudes, knowledge, and problem awareness improved only among those with lower pre-intervention levels. Individuals with higher pre-intervention levels demonstrated low potential for change in these outcomes. The findings of the three articles contribute to PEB intervention research in several ways. First, the dissertation addresses two previously under-researched domains of PEB (SRI and pro-biodiversity behaviour), contributing to evidence-based intervention strategies in these fields (Articles 2 and 3). Second, by relating evidence from sustainable consumption and SRI through a narrative literature review (Article 1) and a conceptual replication of an intervention (Article 2), this dissertation illustrates how a theory-driven comparison of domains is a fruitful approach for PEB intervention research. Third, both empirical articles (Articles 2 and 3) examine the effectiveness of behaviour change interventions for different audience segments. Comparing the findings of the SRI intervention (Article 2) with those for the pro-biodiversity intervention (Article 3) suggests two factors that may influence the effectiveness of interventions for more environmentally engaged audiences: greater receptiveness to interventions (Article 2), and ‘ceiling effects’ due to limited upward potential (Article 3). Overall, this dissertation emphasises the importance of establishing stronger connections between evidence from different PEB research fields and domains, alongside domain- and audience-sensitive evidence. Bringing together disjointed insights from different domains may facilitate the translation of intervention research into practice, a necessary condition for broader implementation in support of transformative change.
