Sustainable Agri-Food Marketing Innovation : Co-Creation and Design Thinking as a Research Method (Poster)
No full textIn response to the global challenges of today, the United Nations Sustainable Development Goals (SDGs) highlight, among others, the need for education for sustainable development (ESD) (Goal 4) and the promotion of sustainable consumption and production (Goal 12). Aligning with these objectives, this research project explores business model innovation for organic box scheme providers, focusing on fruit and vegetable boxes while integrating early childhood ESD through collaborations with childcare facilities. Organic produce delivery via box schemes is a well-established business model in organic agriculture. Many providers already maintain relationships with childcare facilities, supplying food and occasionally offering educational activities. However, these services are rarely integrated into a cohesive offering. This research investigates whether a structured collaboration between organic box scheme providers and early childhood education institutions can enhance the promotion of organic agriculture and ESD while ensuring economic viability. Specifically, the study examines how combining organic produce deliveries with sustainability education can serve as an innovative marketing strategy for organic box schemes. Given that both food delivery and educational services are common but rarely combined, this study employs a mixed-methods research approach that gathers diverse stakeholder perspectives while fostering creativity in business model innovation. Co-creation and design thinking principles are central to this approach, ensuring that the needs and insights of all relevant stakeholders – organic box scheme providers, childcare facilities, and parents – are considered in the innovation process. The presentation outlines how co-creation and design thinking methodologies are applied within the research project, emphasizing a participatory workshop as its core component. Given the complexity of the research topic with the different stakeholder groups being involved, an open but structured approach is crucial to ensure scientific rigor and practical relevance. The research begins with an exploratory phase, using mixed-methods approaches such as online surveys, expert interviews, case studies, and group discussions to capture the diverse perspectives. The insights of this exploratory phase build the basis for the subsequent co-creation phase, where those stakeholders collaboratively develop a prototype business model in a structured workshop employing design thinking techniques. This prototype will later undergo empirical evaluation to assess its feasibility and effectiveness in promoting both organic agriculture and sustainability education. In this presentation, we will examine the research design in detail and explore how academic methodologies can be enhanced to address today’s complex challenges. Even though the research is ongoing, it makes a significant contribution to the academic discourse on sustainable agri-food marketing innovation. By integrating co-creation and design thinking into scientific research, this project not only advances methodological discussions but also demonstrates practical applications for sustainable business models. Ultimately, it offers valuable insights for academics and industry professionals alike, bridging the gap between research and real-world impact in international food marketing
Akzeptiert und integriert? Mitarbeitendenbefragung zur Akzeptanz und Integration von Corporate Influencern im Social Media Recruiting am Beispiel der ROSEN Gruppe
No full textIn einer durch Fachkräftemangel geprägten Arbeitswelt gewinnen innovative Rekrutierungsstrategien an Bedeutung, um den veränderten Anforderungen des Arbeitsmarktes und den Erwartungen potenzieller Bewerber*innen an Authentizität und Transparenz gerecht zu werden. Eine dieser Strategien ist der Einsatz von Corporate Influencern im Social Media Recruiting. Hierbei agieren Mitarbeitende als Markenbotschafter*innen für das Unternehmen. Bislang ist dieses Feld allerdings kaum erforscht, sodass nur wenige empirische Studien zur Integration von Corporate Influencern in Unternehmen sowie zur Einschätzung von Wirkungen existieren. Ziel dieser qualitativen Untersuchung, die auf einer Bachelorarbeit (Achteresch, 2024a) basiert, ist es, anhand halbstrukturierter, problemzentrierter Interviews, die unternehmensinterne Akzeptanz und Integration von Corporate Influencern im Social Media Recruiting am Beispiel der ROSEN Gruppe zu untersuchen. Die Aussagen von acht Mitarbeitenden aus unterschiedlichen Fachabteilungen werden im Rahmen dieser Arbeit interpretiert und diskutiert. Die Ergebnisse zeigen, dass der Einsatz von Corporate Influencern langfristig eine aussichtsreiche Strategie zur Gewinnung von neuen Mitarbeitenden und zur Steigerung der Arbeitgeberattraktivität darstellen kann. Corporate Influencer bieten durch ihre authentische und persönliche Ansprache signifikante Vorteile im Recruiting-Prozess, insbesondere in den frühen Phasen, indem sie die Reichweite, Sichtbarkeit und Glaubwürdigkeit des Unternehmens erhöhen können. Dies kann sich positiv auf die Rekrutierungserfolge auswirken. Gleichzeitig werden jedoch potenzielle Risiken wie Image- und Reputationsschäden sowie rechtliche Konsequenzen aufgezeigt. Dies verdeutlicht die Notwendigkeit einer sorgfältigen Auswahl, Schulung und strategischen Ausrichtung, um diesen Risiken wirksam zu begegnen. Weitere empirische Studien sind erforderlich, um dieses Forschungsfeld umfassend zu erschließen

Job Hopping : Zu oft gewechselt, um gut zu sein?
No full textKolumne Wirtschaftspsychologie
Besonders junge Menschen sind heutzutage oft "Job Hopper", wechseln also in relativ kurzen Abständen regelmäßig den Job. Zeugt das von viel Erfahrung und Wissensdrang - oder ist es ein Zeichen für jemanden, der sich nicht in Teams integriert? Daran scheiden sich in HR die Geister, wie Kolumnist Uwe P. Kanning erläutert
Estimation of Hydraulic Properties of Growing Media from Numerical Inversion of Mini Disk Infiltrometer Data
Get PDFAccurately determining the hydraulic properties of soilless growing media is essential for optimizing water management in container-based horticulture and agriculture. The very rapid estimation of hydraulic properties using a Mini Disk Infiltrometer has great potential for practical use compared to the very time-consuming standard methods. The objectives of this study were (1) to calibrate simulated cumulative stepwise infiltration under different suctions with the measured data from Mini Disk Infiltrometer, (2) to evaluate the efficiency of the Hydrus-2D inverse model to predict water dynamics through substrates, (3) to compare the substrate hydraulic parameters obtained through the numerical inversion model to those obtained via laboratory methods, and (4) to provide recommendations on how to effectively use the MDI-based method for practical applications. This study employs numerical inversion of Mini Disk Infiltrometer (MDI) data to estimate the hydraulic parameters of three different growing media, namely white peat, thermally treated wood fibre (WF4), and Seedling substrate. Infiltration experiments were conducted under suction-controlled conditions using varying initial moisture contents, followed by numerical simulations using the Hydrus-2D model and the Van Genuchten equation to describe the hydraulic parameters. The results demonstrated strong agreement between observed and simulated infiltration data, particularly under moistened conditions, with high R2 > 0.9 values indicating the model’s effectiveness. However, discrepancies were observed for substrates in their initial dry state, suggesting limitations in capturing early-stage infiltration dynamics. The findings highlighted the potential of numerical inversion methods for estimating substrate hydraulic properties but also revealed the need for methodological refinements. Modifying the Van Genuchten model or exploring alternative approaches such as the Brooks and Corey model may enhance accuracy. Extending the suction range of measurement techniques is also recommended to improve parameter estimation. This study provides important evidence that the inverse method based on MDI is an effective tool for rapidly determining the hydraulic functions of substrates, which are important in promoting sustainable horticultural practices. Future research should focus on refining parameter estimation methods and addressing model limitations to enhance the reliability of hydraulic property assessments in soilless growing media
