Ethnic-Racial Socialization in Early Childhood: The Implications of Color-Consciousness and Colorblindness for Prejudice Development

This chapter outlines how early childhood teachers can bring children into conversations surrounding race and racism by drawing on literature on how parents of color discuss these topics. Although educators’ practices surrounding race and racism remain largely unexplored, decades of developmental psychological research indicate that parents of color engage in ethnic-racial socialization practices that are beneficial for children (Hughes et al., 2006). The established dimensions of parental ethnic-racial socialization include (1) cultural socialization, or teaching children about their ethnic heritage and instilling ethnic pride; (2) preparation for bias, or teaching children about racism and preparing them to face discrimination; (3) promotion of mistrust, or warning children about the need to distance themselves from other racial groups; and (4) egalitarianism, or emphasizing the similarities between and equality of all races (Hughes et al. 2006). One consideration to take into account from a developmental perspective is that children’s level of cognitive development impacts how they interpret messages about race. This chapter draws a link between parental ethnic-racial socialization and extends this body of work to school settings, with a focus on teachers. The ideologies of colorblindness and color-consciousness are discussed throughout

A Bacterial Acetyltransferase Destroys Plant Microtubule Networks and Blocks Secretion

The eukaryotic cytoskeleton is essential for structural support and intracellular transport, and is therefore a common target of animal pathogens. However, no phytopathogenic effector has yet been demonstrated to specifically target the plant cytoskeleton. Here we show that the Pseudomonas syringae type III secreted effector HopZ1a interacts with tubulin and polymerized microtubules. We demonstrate that HopZ1a is an acetyltransferase activated by the eukaryotic co-factor phytic acid. Activated HopZ1a acetylates itself and tubulin. The conserved autoacetylation site of the YopJ / HopZ superfamily, K289, plays a critical role in both the avirulence and virulence function of HopZ1a. Furthermore, HopZ1a requires its acetyltransferase activity to cause a dramatic decrease in Arabidopsis thaliana microtubule networks, disrupt the plant secretory pathway and suppress cell wall-mediated defense. Together, this study supports the hypothesis that HopZ1a promotes virulence through cytoskeletal and secretory disruption

Embedding cultural competence in science curricula

Effectively incorporating cultural competence into tertiary institutions is paramount to the creation of cross-cultural settings where undergraduates and academics can develop understandings of how culture and belief systems influence professional decision making. Processes that incorporate cultural competence are viewed as particularly challenging in science disciplines, particularly non-vocational science disciplines where “western” or reductivist ways of teaching and “doing” science remain dominant
