The aim of this systematic review is to answer the question: Is substantial, stable, and long-term weight loss a viable goal for adults with obesity? To answer this question, we conducted a broad systematic search of non-surgical and non-pharmacological obesity treatment studies with the following strict criteria: (a) minimum 3-year follow-up, (b) 5% body mass lost, (c) no continued interventions in the follow-upperiod, (d) prospective design, and (e) less than 30% attrition from the start of the follow-up period. While the search revealed a very large number of published articles, only eight studies met the inclusion criteria. Several of the nonincluded studies report a majority of participants achieving satisfactory weight loss and little regain, especially among studies with continued interventions during the follow-up period. In contrast, the eight high-quality studies included in this study demonstrate a trend of weight regain towards pretreatment baseline. This review concludes that the majority of high-quality follow-up treatment studies of individuals with obesity are not successful in maintaining weight loss over time. The results suggest that excess weight can be lost but is likely regained over time, for the majority of participants. K E Y W O R D S obesity, follow-up, review, weight loss

Physical and emotional intimacy between humans and robots may become commonplace over the next decades, as technology improves at a rapid rate. This development provides new questions pertaining to how people perceive robots designed for different kinds of intimacy, both as companions and potentially as competitors. We performed a randomized experiment where participants read of either a robot that could only perform sexual acts, or only engage in non-sexual platonic love relationships. The results of the current study show that females have less positive views of robots, and especially of sex robots, compared to men. Contrary to the expectation rooted in evolutionary psychology, females expected to feel more jealousy if their partner got a sex robot, rather than a platonic love robot. The results further suggests that people project their own feelings about robots onto their partner, erroneously expecting their partner to react as they would to the thought of ones' partner having a robot.

Introduction Minor mental health problems among service members deployed in combat areas are relatively common, but social support is a protective factor. With the advent of digital communication, as well as more frequent family separations, a stable family support system may be more important than before. In this exploratory study, we aimed to test the relationship between perceived family support and the development of minor psychiatric symptoms during a 4-month naval counter piracy mission in the Gulf of Aden. Materials and Methods We measured minor mental health problems with the general health questionnaire 12 (GHQ-12) and family support at three intervals, 3 weeks before deployment, 2 months into the mission, and at the end of deployment. We used mixed multilevel regression analysis to analyze the main effects of family support and time, as well as their interaction. All analyses were controlled for military rank. Results We found that minor psychiatric symptoms increased at both midway (B = 0.51, P < 0.05) and toward the end of the mission (B = 0.72, P < 0.01). The results also showed that receiving more family support is associated with fewer psychiatric symptoms (B = −0.87, P < 0.01). Family support also moderated the development of symptoms toward the end of the mission (B = −0.73, P < 0.01). The buffering effect was such that service members with a high degree of family support experienced no increase in minor psychiatric symptoms during the deployment. Conclusions The results indicate that naval deployment is associated with a small increase in minor mental health problems and that having a high degree of family support buffers this effect. Efforts to increase support among military families may positively influence the wellbeing of naval sailors during combat missions.

Several people have contributed to the completion of this PhD thesis, and I would like to express my gratitude to them. First, thanks to all of the contributors and participants in the Royal Norwegian Navy. Ragnar Vaernes at Falc Nutec, for stimulating my interest in operational research. My main supervisor Dr. Olav Kjellevold Olsen, without whom this project never would have seen the light of day. Thank you for the guidance, trust, thoughtful discussions, and showing me how to thrive as an academic. My co-supervisor and somnologist par excellence, Professor Ståle Pallesen. My other co-supervisor Dr. Roar Espevik for his hands-on contributions to the data collection and discussions, and Dr. Jørn Hetland for introducing me to shortitudinal multi-level analysis. I would also like to thank my family for all their support. I also wish to thank Sondre Aasen Nilsen for all the therapeutic debriefings. Lastly, a special thanks to Veronica for making me more resilient. Thanks for all the love.
