AbstractChallenging behaviors interfere with children's learning, prosocial interactions, and family dynamics. Parents may benefit from receiving training in behavioral principles to prevent and reduce challenging behaviors, especially in low‐resourced communities where services are scarce and scattered. This study implemented an adapted online training on behavioral principles with 15 parents of children with developmental disabilities in Paraguay. Analysis of the pretest and posttest assessment data indicated that parents' knowledge of behavioral principles overall increased, and some changes were found in the reported usage of positive parenting practices. Moreover, qualitative interviews with participants revealed that the intervention delivery in Paraguay was considered acceptable. Therefore, providing access to online training in low‐resourced communities may be a feasible and accessible intervention for parents of children with developmental disabilities.

When military community closure occurs, it can be challenging for service members and the surrounding community. Given that services and social networks disappear; this is particularly salient in overseas locations. Few studies have systematically assessed the impact of base closure on military community members. In the present study, 743 soldiers, 114 Army civilian employees, and 54 military spouses living in two closing U.S. military communities in Germany were surveyed about transformation stressors, mental health, and factors associated with better adjustment such as individual coping, leadership behaviors, and community cohesion. While individual coping was associated with fewer sleep problems, and individual coping and leadership were associated with less psychological distress, community cohesion generally overrode these effects in the final step of regression models. Thus, while coping and leadership are important, community connection appears to confer benefits to the affected individuals even in the context of base closure.

An uncontrolled gas leak from 25 March to 16 May 2012 led to evacuation of the Total Elgin wellhead and neighbouring drilling and production platforms in the UK North Sea. Initially the atmospheric flow rate of leaking gas and condensate was very poorly known, hampering environmental assessment and well control efforts. Six flights by the UK FAAM chemically instrumented BAe-146 research aircraft were used to quantify the flow rate. The flow rate was calculated by assuming the plume may be modelled by a Gaussian distribution with two different solution methods: Gaussian fitting in the vertical and fitting with a fully mixed layer. When both solution methods were used they compared within 6% of each other, which was within combined errors. Data from the first flight on 30 March 2012 showed the flow rate to be 1.3±0.2kgCH4s-1, decreasing to less than half that by the second flight on 17 April 2012. δ13CCH4 in the gas was found to be -43‰, implying that the gas source was unlikely to be from the main high pressure, high temperature Elgin gas field at 5.5km depth, but more probably from the overlying Hod Formation at 4.2km depth. This was deemed to be smaller and more manageable than the high pressure Elgin field and hence the response strategy was considerably simpler. The first flight was conducted within 5 days of the blowout and allowed a flow rate estimate within 48h of sampling, with δ13CCH4 characterization soon thereafter, demonstrating the potential for a rapid-response capability that is widely applicable to future atmospheric emissions of environmental concern. Knowledge of the Elgin flow rate helped inform subsequent decision making. This study shows that leak assessment using appropriately designed airborne plume sampling strategies is well suited for circumstances where direct access is difficult or potentially dangerous. Measurements such as this also permit unbiased regulatory assessment of potential impact, independent of the emitting party, on timescales that can inform industry decision makers and assist rapid-response planning by government.
