Recommender systems have emerged to help individuals with finding interesting products. As a result, the consumer welfare enhances due to the increased product variety. In other words, recommender systems are essential for increasing consumers welfare, which ultimately leads to an increase of economic and social welfare.Typically, recommender systems use the collective wisdom of individuals for exposing individuals to products which best fits their preferences. More precisely, the most like-minded individuals are considered by the recommender system to provide individuals recommendations. This is commonly referred to as collaborative filtering.In this dissertation, we present hypothesis-based collaborative filtering (HCF) to expose individuals to products which best fits their preferences. HCF retrieves like-minded individuals based on the similarity of their hypothesized preferences by means of machine learning algorithms hypothesizing individuals' preferences.
Experiences of violence, sexual abuse, accidents, disasters or deaths of close relatives or friends, and other extreme situations can lead to trauma-related disorders. Since 2018, the World Health Organization has distinguished four such disorders in its classification list: "classic" and complex post-traumatic stress disorder, as well as prolonged grief disorder and adjustment disorder. These long-term effects are described in detail in the book. In recent years, a variety of interventions have been developed to effectively treat these disorders. This 5th edition has been largely reorganized due to the groundbreaking innovations in which the editor played a decisive role on an international level. Among the innovations are the chapters on: - Complex post-traumatic stress disorder - Childhood violence and its consequences - Low-threshold and innovative interventions - Methods of cognitive behavioral therapy - Psychodynamic approaches The handbook on psychological trauma-related disorders.
