Barriers to successful collaboration between startups and established corporates in Germany: perspectives from corporate venture capital units, startups, and venture builder
Publication . König, Louise Philippa; Castro, João
Corporations prioritize partnerships with startups due to increasing demands for innovation. Numerous partnerships fail to provide anticipated results. The research analyzes collaboration obstacles from the viewpoints of startups, Corporate Venture Capital (CVC) units, and Venture Builders throughout Germany. Research through qualitative interviews and Gioia methodology reveals that cultural and procedural misalignments, including slow decision-making processes, internal resistance, and different work styles, are the primary obstacles identified in the study. In practice, strategic misalignment has proved less influential than is commonly stated. According to the study findings, corporations must enhance their internal preparedness levels while improving cultural compatibility and stakeholder coordination.

Objective: To estimate the mortality attributable to passive smoking in the population aged 35 years old and older, by gender, in the 27 Brazilian state capitals, from 2009 to 2021. Methods: A prevalence-dependent method was used, based on the calculation of population attributable fractions (PAF). Deaths from diseases causally related to passive smoking were obtained from the Mortality Information System of the Brazilian Unified Health System (SIM/SUS); prevalence data were taken on SHS exposure were obtained from Vigitel surveys (2009–2021); and relative risks were obtained from a meta-analysis. Mortality attributable to passive smoking and mortality rates were estimated by capital city, year, gender, and cause of death. Trends in crude mortality rates attributable to passive smoking were analyzed using joinpoint regression models. Results: Passive smoking accounted for 64,913 deaths in all Brazilian state capitals between 2009 and 2021. Cardiovascular diseases were the main cause of death in both genders. The mortality rate attributed to passive smoking decreased from 33.1/100,000 deaths in 2009 to 15.4/100,000 deaths in 2021. This reduction was observed in all 27 Brazilian state capitals, both overall and by gender. Conclusion: Passive smoking was responsible for 1.4 of all deaths in Brazil during the period 2009-2021 and showed a favorable trend, with rates decreasing by half during the period.
Trust dynamics in AI customer service: designing AI-human interactions in European digital channels
Publication . Ponte, Federico de; Castro, João
AI automation promises efficiency but can undermine customer trust when service interactions become unclear or unreliable. This thesis explores how European organizations balance AI efficiency with human connection in customer service through augmentation rather than pure automation. Using a mixed-methods approach, the study combines three expert interviews with a business case analysis of Hilti's digital channel strategy to develop a theoretical framework for AI-human service design. Interview findings reveal implementation strategies including structured knowledge bases with continuous learning, sentiment-based escalation triggers, and role transformation from ticket processing to knowledge maintenance. Enterprise implementations prioritize "same people, more business" philosophies, while startup contexts achieve dramatic efficiency gains and team size reductions through AI agents. A framework was developed, which incorporates governance elements aligned with GDPR and emerging AI Act requirements, including risk assessment procedures and human oversight protocols. This thesis contributes a theoretical model for trust-calibrated AI-human service design that invites empirical validation and offers structured hypotheses to guide future research.
Cancer Prevention Literacy Questionnaire (CPL-Q)

Background: Health literacy is a key determinant of health, shaping individuals ability to understand and act on health information. Low cancer literacy is associated with fatalistic beliefs and reduced participation in prevention and screening programmes. Although around 40% of all cancers are preventable, public awareness of modifiable risk factors remains low. The European Code Against Cancer (ECAC), developed under the World Code Against Cancer Framework, aims to strengthen prevention knowledge; however, tools to measure cancer prevention literacy, and therefore evaluate its impact, are lacking. This study aimed to develop and validate a questionnaire to assess ‘cancer prevention literacy’ in adults from the general population. Methods: We conducted a methodological study to develop a questionnaire measuring ‘cancer prevention literacy’ in adults from the general population using the Integrative Model of Behavioural Prediction as theoretical framework. Questionnaire development followed a three-stage process: (1) a literature review and two-round Delphi process to select and refine items; (2) a third Delphi round, complemented by readability checks, face-validity assessment, and cognitive testing to evaluate item relevance, clarity, and representativeness; and (3) a pre-test and psychometric analysis to assess construct validity. Results: The final Cancer Prevention Literacy Questionnaire (CPL-Q) consists of a 10-question validated instrument comprising 58 items, with selected items incorporating the verbatim wording of the recommendations from the ECAC, 4th edition. Strong expert agreement was achieved through an iterative Delphi process, and content and face validity indicated that the items were comprehensible, relevant, and appropriate. Psychometric analyses, including exploratory and confirmatory factor analysis, provide preliminary support for the instrument’s construct validity, with initial evidence suggesting acceptable reliability. Conclusion: The CPL-Q provides a standardised instrument to measure ‘cancer prevention literacy’ and to assess the impact of Regional Codes Against Cancer through monitoring and benchmarking changes over time. It also offers a practical tool to identify gaps in ‘cancer prevention literacy’ within specific populations and to support international comparisons and longitudinal evaluations, thereby contributing to the evidence base for cancer prevention policies.
Behind the delay: functional barriers and alignment challenges in invoice processing
Publication . Nyerges, Balázs; Almeida, Marta
This Work Project explores the behavioral, structural, and operational factors contributing to delays in CompanyX’s invoice resolution process, with a focus on cross-functional misalignment. An initial analysis of internal data was used to identify country units for follow up qualitative research. Semi-structured interviews were conducted and thematically coded to uncover recurring bottlenecks and best practices. The findings revealed that while processes are standardized, execution varies due to rebate invoice complexity, market structure, and limited
communication with headquarters. Five actionable recommendations are proposed to improve transparency, accountability, and cross-functional alignment without adding formal KPIs.
