description: A cross-sectional study was performed to examine how the students in a master's program in accounting/auditing perceive their own learning and their capacity for lifelong learning, taking into consideration various learning activities. Our findings suggest that, from the students' perspective, the most important learning activities are lectures and participation in colloquium groups. Students do not experience reading course literature as a particularly important learning activity.

title: Replication Data for: Temperature conditions in artificial sea turtle nests: Towards optimized hatchery management

description: Data from nest temperature from a hatchery on the Pacific coast of Guatemala. Temperature loggers were buried in 22 nests of Olive Ridley sea turtle (<i>Lepidochelys olivacea</i>) in 2021. The temperature was measured every hour for the whole incubation time.<br><b>Abstract from related publication:</b>Climate change poses a significant threat to species with temperature-dependent sex determination, such as sea turtles. Their conservation often involves relocating nests to hatcheries, which is also crucial on the Pacific coast of Guatemala, where virtually no hatchlings emerge from natural nests. Populations there rely heavily on hatcheries, yet nest temperature monitoring in relation to environmental and management factors is rarely conducted. Research is needed to improve artificial nest management and hatchery design. This study investigated how distance to the hatchery wall, number of eggs, position in the nest, development period, season, and weather conditions influenced temperature variation in Olive Ridley Turtle (Lepidochelys olivacea) nests. We generally found nest temperatures within viable ranges and near the pivotal temperature for Olive Ridleys. The pivotal temperature of Olive Ridley was exceeded 6%–21% of the time during the thermosensitive period of all nests (starting days 9–15 and ending days 33–37 of incubation), and the upper thermal tolerance limit was rarely reached. However, nests closer to concrete walls were up to 1°C warmer than those farther away, and 30–40 more eggs per nest raised average temperatures by 0.7°C. These findings suggest that distance to hatchery walls and egg numbers per nest can be tools to manipulate nest temperatures and sex ratios. The sex ratios in this study were slightly female-biased. However, optimal sex ratios remain poorly understood, and reliance on ex situ incubation may reduce population adaptability to environmental changes. Ex situ nest conditions in our study displayed lower temperatures than potential in situ conditions, which exceeded the lethal threshold in 86% (z-test, p &lt; 0.001) of the measurements. Our study emphasizes the need for careful hatchery management to safeguard sea turtles against the effects of climate change but also to avoid the consequences of overcompensation due to mismanagement.

title: List and lexical-semantic analysis of 600 predefined keywords for rule-based NLP to extract themes within and beyond R-strategies in circular economy definitions

description: Thematic identification was applied in this study through a combination of deductive and abductive reasoning to ensure both structured categorization and flexibility in capturing emerging concepts. The process began with a deductive approach, selecting initial keywords for each circular economy strategy based on the 10R framework. These keywords formed the foundation for strategy classification. An iterative abductive refinement followed, where definitions were manually reviewed to identify missing or alternative terms, which were then systematically integrated. During this process, the initial keyword set was used as input for the previously developed NLP model. The model was continuously tested and refined, enabling data-driven expansion while maintaining alignment with the 10R framework.Moreover, a linguistic categorization analysis (lexical-semantic analysis (Hua et al., 2015)) was conducted, classifying all keywords into three groups: lexical matches (direct variations of the strategy name), semantic equivalents (synonyms), and contextual inferences (concepts requiring interpretation).

title: Python code for hierarchical cluster analysis of detected R-strategies from rule-based NLP on 500 circular economy definitions

description: The dataset used in this analysis consists of 500 peer-reviewed circular economy (CE) definitions systematically collected from key academic sources. The definitions were processed using a rule-based NLP model to extract the presence of R-strategies (R0-R9), which operationalize circularity in CE frameworks. Each definition was analyzed for the presence of these strategies, and the results were structured into a binary format (1 if detected, 0 if not) for statistical and clustering analysis.The hierarchical cluster analysis was performed on this dataset to reveal co-occurrence patterns among R-strategies, using Ward’s method for clustering and Euclidean distance as the similarity metric. The resulting dendrogram visually represents how different strategies are conceptually related based on their co-occurrence in CE definitions.This Python code was optimized and debugged using ChatGPT-4o to ensure implementation efficiency, accuracy, and clarity.<br><br>

title: Supplemental data for: Holding on or heading up? The roosting preferences of laying hen pullets: A traditional and modelling approach

description: The files submitted here contain data collected for the thesis titled "Holding On or Heading Up? The Roosting Preferences of Laying Hen Pullets: A Traditional and Modelling Approach". The purpose of this research was to determine whether laying hen pullets of different strains would prefer to roost on a structure that allows their toes to wrap versus a structure that is more elevated. We also investigated the association between the pullets' foot length and their use of perches versus platforms within their housing system. Finally, we recreated this observational data using a mechanistic model that described the pullets' movement between the floor, the ramps, and the roosting structures and used the solved equations to support our observational findings. Observational data was analyzed using SAS Proc GLIMMIX, and the mechanistic model's differential equations were iterated and solved using a python code.
