Children's evaluations of and reactions to racial discrimination.

Despite the potential benefits of children's confrontations of other children's racial biases-especially for targets of bias-little is known about how young children react upon observing instances of racial discrimination. In the present research, child participants completed a novel measure designed to test their reactions to another child's racially discriminatory behavior. The measure presented scenarios in which a protagonist who matched the participant's race (Asian, Latinx, or White) repeatedly excluded Black children from different social activities. Participants evaluated the protagonist's behavior and had an opportunity to confront the protagonist. Both a pilot study and a full preregistered study revealed that the novel measure had high reliability within participants and substantial variability across participants (pilot study: N = 54 U.S. White 5-7-year-olds, 27 girls, 27 boys, median household income range of $125,001-$150,000; full study: N = 126 U.S. 4-10-year-olds, 33.33% Asian, 33.33% Latinx, 33.33% White, 56 girls, 70 boys, median household income: $120,001-$125,000). In the full study, older children and children whose parents reported more racial socialization rated the protagonist's behavior more negatively; older children were also more likely to confront the protagonist. Neither participants' own race nor their prior exposure to racial diversity impacted their evaluations or confrontations of discrimination. The results have implications for understanding children's potential to serve as agents of social change by regulating other children's racial biases and behaviors.

Long-Term Follow-Up of Intralobar Bullae After Endobronchial Valve Treatment for Emphysema.

Endoscopic lung volume reduction using unidirectional endobronchial valves is a new technique in the treatment of patients with severe emphysema. However, the movements of the thoracic structures after endobronchial valves insertion are still unpredictable We report the unusual outcome of six patients after valves insertion in the left upper lobe. They all developed a complete atelectasis of the target lobe, a pneumothorax and sequential genuine bullae in the treated left lung of unknown etiology. The chest CT scan prior to the valves insertion was unremarkable. Three patients developed an air-liquid level in the bullae the day before a bacterial infection of their left lower lobe. The three other patients had an uneventful spontaneous resolution of their bullae at long-term follow-up. Therefore, a conservative attitude should be followed in this particular setting.
