Resilient Pedagogy: Practical Teaching Strategies to Overcome Distance, Disruption, and Distraction

Resilient Pedagogy offers a comprehensive collection on the topics and issues surrounding resilient pedagogy framed in the context of the COVID-19 pandemic and the social justice movements that have swept the globe. As a collection, Resilient Pedagogy is a multi-disciplinary and multi-perspective response to actions taken in different classrooms, across different institution types, and from individuals in different institutional roles with the purpose of allowing readers to explore the topics to improve their own teaching practice and support their own students through distance, disruption, and distraction

Communication Accommodation: Law Enforcement and the Public

While there is a burgeoning literature on diverse aspects of intergroup communication and some attention to media depictions of police officers and policing, very little research addresses communicative dimensions of police-civilian encounters. This is important to the extent that while it has been estimated that the vast amount of police training is devoted to physical compliance issues, 98% of actual law enforcement practice revolves around communicating with the public and its safety needs. Thus, the communication between police officers and civilians warrants examination. In this chapter, we overview the separate literatures on attitudes toward the police and communication accommodation theory. The findings of three studies are presented exploring the role of accommodation, alongside socio-demographic and other variables, in predicting attitudes toward police. The three studies encompass three different populations: English-speaking adults, Spanish-speaking adults, and university students. Analyses reveal similar results across the samples. In general, accommodation by officers predicts civilians’ rating of officer performance as well as satisfaction when interacting with the police. These findings suggest that more attention should be directed at developing communication skills in general and accommodative ones in particular

Terminal alkene formation by the thioesterase of curacin A biosynthesis: Structure of a decarboxylating thioesterase

Curacin A is a polyketide synthase (PKS)-non-ribosomal peptide synthetase-derived natural product with potent anticancer properties generated by the marine cyanobacterium Lyngbya majuscula. Type I modular PKS assembly lines typically employ a thioesterase (TE) domain to off-load carboxylic acid or macrolactone products from an adjacent acyl carrier protein (ACP) domain. In a striking departure from this scheme the curacin A PKS employs tandem sulfotransferase and TE domains to form a terminal alkene moiety. Sulfotransferase sulfonation of β-hydroxy-acyl-ACP is followed by TE hydrolysis, decarboxylation, and sulfate elimination (Gu, L., Wang, B., Kulkarni, A., Gehret, J. J., Lloyd, K. R., Gerwick, L., Gerwick, W. H., Wipf, P., Håkansson, K., Smith, J. L., and Sherman, D. H. (2009) J. Am. Chem. Soc. 131, 16033-16035). With low sequence identity to other PKS TEs (<15%), the curacin TE represents a new thioesterase subfamily. The 1.7-Å curacin TE crystal structure reveals how the familiar α/β-hydrolase architecture is adapted to specificity for β-sulfated substrates. A Ser-His-Glu catalytic triad is centered in an open active site cleft between the core domain and a lid subdomain. Unlike TEs from other PKSs, the lid is fixed in an open conformation on one side by dimer contacts of a protruding helix and on the other side by an arginine anchor from the lid into the core. Adjacent to the catalytic triad, another arginine residue is positioned to recognize the substrate β-sulfate group. The essential features of the curacin TE are conserved in sequences of five other putative bacterial ACP-ST-TE tridomains. Formation of a sulfate leaving group as a biosynthetic strategy to facilitate acyl chain decarboxylation is of potential value as a route to hydrocarbon biofuels. © 2011 by The American Society for Biochemistry and Molecular Biology, Inc
