- Consumer attitudes and behaviors toward direct-to-consumer genetic testingPublication . Douss, Elyssa; Elmashhara, Maher GeorgesDirect-to-consumer genetic testing (DTC-GT) is a rapidly expanding sector within the healthcare industry. It offers individuals access to personal genetic information related to ancestry and health predisposition. However, DTC-GT poses significant challenges for consumers, particularly in terms of Data privacy. This study aims to examine consumer attitudes and behaviors toward ethnicity-based genetic testing and key factors influencing consumers to use or not use DTC-GT. To investigate this phenomenon, we conducted 10 in-depth semi-structured interviews with diverse participants to understand their perception of genetic services. The findings reveal that curiosity is the primary motivation for potential customers, it improves their sense of identity and connection to their heritage. Nevertheless, there are significant ethical concerns regarding data privacy and the potential misuse of genetic information. Participants expressed doubts about the reliability of genetic tests and the transparency of data management practices. Based on the findings, this study outlines the theoretical contributions and offers practical managerial insights for managers of DTC-GT platforms on how to improve trust and reliability for consumers.
- Exploring sustainability patterns in household food purchasing : a data analytics approachPublication . Teixeira, Rui Filipe Peixoto; Silva, Vera Lúcia Miguéis Oliveira eAt a time when global environmental challenges are pressing and consumer options are more diversified than ever, there is an urgent need to integrate sustainable practices with the growing availability of food items that may not always be beneficial to healthy living. This work describes a critical step in using food retailers’ data to turn complicated consumer interactions into meaningful insights. This initiative seeks to find opportunities to support more environmentally friendly and nutritionally healthy consumer choices by strategically analysing consumption habits. This thesis used a complex approach to data cleansing, which included a variety of standardisation and normalisation procedures to match diverse data structures and formats. The outcome of these efforts was the merging of three data tables, which converged to form an integrated data table that not only contained a retailer's product offerings, but also included the complete nutritional information and calculated environmental implications of each product. An important methodological highlight is the classification of clients into three unique segments based on macronutrient and micronutrient consumption, as well as environmental effect. This three-dimensional categorization is crucial, as it gives a full consumer profile and enables for a detailed knowledge of consumption behaviours across three important dimensions. This thesis lays the framework for future research on the sustainability and nutritional effect of consumer behaviours. It uncovers critical information that might drive policy decisions targeted at directing household consumption towards more sustainable and healthier results by segmenting consumer data in great detail.
