team learning process of constructive conflict use more structuring behaviors in earlier time periods but fewer of these behaviors in later time periods, compared with leaders of less effective teams. Again, these findings emphasize the need to include a temporal perspective for understanding team learning dynamics.

Taking important steps toward addressing this need, this special issue offers new insights into the complex phenomenon of team learning by advocating a temporal perspective. The four articles showcase different approaches to implementing a temporal perspective in team learning research, ranging from qualitative to quantitative methodologies and from longitudinal to micro-temporal approaches. All four contributions were presented and discussed during a symposium at the Annual INGRoup conference in Helsinki 2016. The authors are from four different countries and represent five different disciplines inUS Pediatrician Practices and Attitudes Concerning Childhood Obesity: 2006 and 2017.
To compare primary care pediatricians' practices and attitudes regarding obesity assessment, prevention, and treatment in children 2 years and older in 2006 and 2017. National, random samples of American Academy of Pediatrics members were surveyed in 2006, 2010, and 2017 on practices and attitudes regarding overweight and obesity (analytic n = 655, 592, and 558, respectively). Using logistic regression models (controlling for pediatrician and practice characteristics), we examined survey year with predicted values (PVs), including body mass index (BMI) assessment across 2006, 2010, and 2017 and practices and attitudes in 2006 and 2017. Pediatrician respondents in 2017 were significantly more likely than in 2006 and 2010 to report calculating and plotting BMI at every well-child visit, with 96%
