No full textThis study analyzes political ads aired on Spanish-language radio stations in the US during the midterm elections of 2022. With a focus on media policy, this research offers new evidence about the role of political groups in using this medium to engage and mobilize the Latino vote. Our findings indicate that, although radio is a relatively affordable platform for political advertising, it is still underutilized by politicians and interest groups. The evidence shows that traditional Democratic-leaning organizations and also right-wing conservative groups invested millions of dollars to capture the attention of the diverse eligible Latino voters. Additionally, this study finds that specific issues commonly associated with the Latino community, such as immigration, are not necessarily the main subjects of interest for groups using radio for political advertising. The importance of radio for Latinos makes this research relevant from a theoretical and policy-oriented perspective

Restoring Wonder: Play, Inquiry, and Humanizing Pedagogies in Early Childhood Teacher Education
No full textAt a writing retreat in the middle of the woods, we considered the trees. Inspired by our surroundings, we discussed possibilities for how we might demonstrate an inquiry cycle with our undergraduate teacher candidates. We considered our spaces: the buildings in which we teach our classes, the university campus, and the broader community. We reminded one another of our campus quad and its status as an arboretum, owing to the diverse variety of trees there, representing myriad species and varieties. We posed questions. “What do we have available within our reach? What do we have that students can literally touch? How can we help students be in a place they seemingly already know?” Christie asked. “The trees,” Xiaoying mused. “We see the trees, but we don’t really KNOW them.” And thus, our inquiry question was born: How can we help our teacher candidates to KNOW the trees
Host-Associated Beneficial Gut Microbiota Boosts Induced Immunity and Limits Immune Deployment Costs in Bumblebees
No full textEcological immunology posits that variation in host resistance to infection may be attributed partly to the ecological and evolutionary costs of immunity. While the deployment of immune defence is necessary to combat pathogenic infection, hosts pay energetic and other costs for activation. Host-associated beneficial microbiota have been shown to affect multiple host traits, including immunity, but how interactions with these microbial communities may mitigate the costs of immune activation remains an open question. For apid bees, including eusocial bumblebees, core members of the adult gut microbiota contribute to a variety of fitness-relevant traits and provide a key ecological and evolutionary relationship contributing to ecological success. Here we test the hypothesis that the host-associated microbiota provides benefits to bumblebee immunity, including the mitigation of the costs associated with inducible immune responses. Freshly emerged germ-free adult workers were supplemented with their native microbiota via experimental faecal transplants from nestmates or kept deprived of their native microbiota inoculum. We assessed functional measures of induced immunity and assessed the costs of non-pathogenic immune activation for survival. In support of our hypothesis, we find that microbiota supplementation strengthened functional antibacterial immunity. Moreover, although we observed a cost of immune activation for survival, the cost was much greater for bees deprived of their native gut microbiota compared to those supplemented. Thus, we provide evidence that in addition to other roles, the microbiota mitigates costs of immune deployment. This demonstrates a key role for host-associated microbiota in the realization of induced immune defence, and contributes more broadly to our understanding of microbiota-immune interactions in the context of ecological immunology
