Independent verification of published results is crucial for ensuring research quality and promoting further advancements. However, reproducibility in data-focused research is a growing concern across disciplines. Our research aims to improve the reproducibility of interaction-based emotion recognition research. For this, we evaluate current data sharing practices in this area. We survey these practices by examining 100 publications published from 2014 to 2024. We examined the characteristics of shared and not shared data, trends over time, and influences of authorship and publication type. We requested data from the publications’ authors for which the data was not shared as part of the publication. Afterwards, we evaluated the reasons we were given as to why the data could not be shared. Overall, we observed limited data sharing, with only 15 out of 100 publications providing their data, even after we sent requests for data to authors. We only received data for four publications after sending requests via email to the authors. Furthermore, the shared artifacts are often insufficient for full reproducibility. We found that, data was shared along a journal article more often than a conference publication. However, data sharing increased noticeably in recent years, particularly since 2021. Overall, the lack of data sharing hinders the reproducibility and comparability of the research results. In the future, it is necessary to encourage the data sharing along publications by introducing mandatory guidelines.

Building upon a previously published framework, the present study systematically explores how amplitude envelope parameters and tonality influence emotional perception along the valence–arousal dimensions. Using the modular synthesis, twelve function-specific stimuli were created and evaluated by 27 participants. The use of major versus minor tonalities did not yield consistent or statistically interpretable effects on emotional perception. Based on the survey results, it is assumed that the number of bursts within a certain time determines the value of the valence: The shorter the bursts, the lower the valence. It is assumed that modulating the fundamental frequency tends to a higher arousal.

ER - TY - CHAP A1 - Joosten, Jan A1 - Hahn, Alexander A1 - Totzek, Dirk A1 - Gaugler, Tobias T1 - True Cost Pricing: The Impact of Emotions on Price Perceptions T2 - Conference of the Bavarian Service Research Cluster (BSRC) N2 - This research provides new insights into consumer reactions and acceptance of true cost price labels. It focuses on how design elements and cognitive and emotional responses impact perceived price fairness and purchase intent towards food prices that include externalities. These insights are crucial for policymakers, marketers, and businesses promoting sustainable consumption practices to communicate true cost prices effectively. The true cost accounting (TCA) method integrates external costs, such as environmental impacts, into the market price of food products. The four dimensions included in this study are greenhouse gas emissions, nitrogen derivatives, energy consumption, and biodiversity loss created by three food product categories. Findings show that TCA information on true cost price labels increases the perceived price fairness. Building on behavioral pricing literature, the study also compares label design variants of TCA information per externality in absolute (currency) versus relative (percentages) markup prices, finding that relative true cost price labels are easier for consumers to understand and lead to higher purchase intent. Using innovative UX research methods like facial coding and eye tracking, this research investigates the emotional drivers behind these choices, revealing that surprise and confusion mediate the relationship between true cost price labels and purchase intent. The counter-intuitive finding suggests that even subtle emotional cues can steer consumer intent.

Recognizing the increasing speed of innovation, this framework addresses a critical gap by systematically evaluating the innovation maturity of a target in mergers and acquisitions (M&A). Drawing on a comprehensive analysis of both academic literature and industry practices, we integrate multiple innovation management frameworks to deliver a unified approach encompassing strategic, organizational, and operational perspectives. The iterative research process involved three iterative feedback loops to develop the framework, including qualitative expert sessions, surveys, and quantitative feedback from industry experts, refining the framework to ensure its robustness and practical relevance. The final model comprises five second-order constructs: Process and Governance, People and Culture, External Environment, Resources & Funding, and Innovation Strategy, each broken down into detailed first-order constructs. The study contributes incrementally by providing the first theoretically and practically validated framework explicitly tailored for innovation assessments in due diligence contexts. It further introduces flexibility through two formats: a Quick Innovation Scan for rapid, sell-side assessments and an Extended IDD for comprehensive, buy-side evaluations. This adaptability enables stakeholders, including transaction advisors and private equity investors, to perform timely and contextually appropriate innovation evaluations, ultimately supporting informed strategic decision-making and risk assessment.

However, a rapidly growing interest lies in leveraging generative artificial intelligence (AI) to brainstorm new product and service ideas. This study conducts a comparative analysis of ideas generated by human professionals and an AI system. The results of a blind expert evaluation show that AI-generated ideas score significantly higher in novelty and customer benefit, while their feasibility scores are similar to those of human ideas. Overall, AI-generated ideas comprise the majority of the top-performing ideas, while human-generated ideas scored lower than expected. The executive's emotional and cognitive reactions were measured during the evaluation to check for potential biases and showed no differences between the idea groups. These findings suggest that, under certain circumstances, companies can benefit from integrating generative AI into their traditional idea-generation processes.

Especially in the legal realm, risks are typically collected heuristically or deductively, e.g., by referring to fundamental right violations. Following a user-centered design credo, research on usable privacy has shown that a user-perspective on privacy risks can enhance system intelligibility and accountability. However, research on mapping the landscape of user-perceived privacy risks is still in its infancy. To extend the corpus of privacy risks as users perceive them in their daily use of technology, we conducted 9 workshops collecting 91 risks in the fields of web browsing, voice assistants and connected mobility. The body of risks was then categorized by 11 experts from the legal and HCI-domain.
