From 1978 to 1985, Bosse performed sociological fieldwork at schools in
Northwest Province, Cameroon. During that period, he also did research in
London,
Heidelberg, and
Melbourne as a visiting fellow. From 1984, Bosse performed sociological research in
Papua New Guinea for many decades, including an in-depth study on "becoming a Papua New Guinean" at
Passam National High School in Paliama, which is now part of
Wewak Rural LLG,
East Sepik Province, Papua New Guinea. Bosse also carried out research on the concept of
group analysis (). Bosse made various contributions to sociology, including intercultural comparison on the socialization of violence in Africa and
Papua New Guinea, and male willingness to use violence and its socialization in different cultures (
see Freud's concept of
sublimation); introduction of group analytical research into sociology; extension of ethnopsychoanalysis (
see Paul Parin, known as the co-founder of ethnopsychoanalysis) to the study of ethnoanalysis; the connection between theology and sociology; criticism of
cultural imperialism; and the
reciprocity hypothesis, which states that societies are not only based on the exchange of goods or money, but also on prestige, reputation, art, objects of value, and so forth. ==Personal life and death==
