- Decentralized autonomous organizations (DAOs)—collectively owned human-machine systems deployed on a blockchain that self-govern through smart contracts and the voluntary contributions of autonomous community members—exhibit the potential to facilitate collective action in managing digital commons. Yet the promise of decentralization and collective action is difficult to sustain. To this end, this paper critically examines the transformational potential of DAOs in the case of decentralized finance. Using a polycentric governance lens, we contribute to the literature on technology-enabled forms of organizing with a model explaining the transformational potential of DAOs to facilitate collective action in digital commons. Our study highlights that (1) DAOs are a new form of organizing enabled by blockchain technology in which individuals are free to pursue their objectives within a general system of rules enforced by smart contracts, (2) collective action for managing digital commons can be sustained through a set of three mechanisms—sustained participation, collective direction, and scaled organizing, and (3) DAOs tend to strike a balance between centralized and fully decentralized or community-based governance by implementing a polycentric governance system involving a combination of human and machine agency that creates skin in the game.

- Roux-en-Y gastric bypass (RYGB) surgery is an established, effective treatment for severe adolescent obesity. Long-term dietary intake and the relationship to eating-related problems are scarcely evaluated in this population.Assess changes in dietary intake in adolescents after RYGB and explore associations between dietary intake and eating-related problems.Multicenter study in Swedish university hospitals.Diet history, binge eating scale (BES), and Three-Factor Eating Questionnaire were assessed preoperatively and 1, 2, and 5 years after RYGB in 85 adolescents (67% female) aged 16.5 ± 1.2 years with a body mass index (BMI) of 45.5 ± 6.0 kg/m2 and compared with control individuals at 5 years.Five-year BMI change was -28.6% ± 12.7% versus +9.9% ± 18.9% in RYGB patients versus control individuals (P < .001). Through 5 years, RYGB adolescents reported reduced energy intake, portion size of cooked meals at dinner, and milk/yoghurt consumption (P < .01). The BES scores were 9.3 ± 8.3 versus 13.4 ± 10.5 in RYGB patients versus control individuals (P = .04). Association between BES score and energy intake was stronger in control individuals (r = .27 versus r = .62 in RYGB patients versus control individuals, P < .001). At 5 years, lower energy intake was associated with greater BMI loss in all adolescents (r = .33, P < .001). Higher scores in BES and uncontrolled and emotional eating were associated with higher energy intake, cooked meals, candies/chocolates, cakes/cookies, desserts, and sugary drinks (r > .23, P < .04) and lower intake of fruits/berries (r = -.32, P = .044). A higher score in cognitive restraint was associated with a higher intake of cereals and fruits/berries (r > .22, P < .05) and a lower intake of sugary drinks (r = -.24, P< .03).To support optimization of long-term outcomes in adolescent RYGB patients, it is important to provide management strategies to reduce energy intake. Monitoring eating-related problems could identify potential individuals at risk of poor weight loss and to initiate treatment interventions.
