Same-Sex Kissing and Having a Gay or Lesbian Child: A Bridge Too Far? Parent-Child Similarities in Homophobic Attitudes and Observed Parental Discomfort.

This study examined parent-child similarities in homophobic attitudes and observed parental discomfort with coming-out vignettes in interactions with their adolescent children (14-18 years old). Based on gender schema theory and the family process model we expected parent-child similarities in homophobic attitudes to be stronger in same-gender dyads. Further, we expected that observed parental discomfort with coming-out vignettes would occur and is stronger when the gender of the parent, child, and character in the vignette match.

Ethnic representation and stereotypes in mathematics and Dutch language textbooks from the Netherlands.

The current study examined ethnic representation and stereotypes in textbooks from two core secondary school subjects: maths and Dutch. We examined all 25 hard-copy textbooks used in first-year secondary schools in the Netherlands in 2019, and coded characters' ethnic background, competence-related activities, and occupational status. Ethnicity was identifiable for 8897 characters.

Invasive brown widow spiders avoid parasitism despite high densities.

Invasive species are sometimes less susceptible to natural enemies compared to native species, but the mechanism is often unclear. Here we tested two potential mechanisms for lower parasitism of invasive species: density-dependent parasitism and preference for human-dominated habitats. We investigated how variation in host density and habitat type affect egg sac parasitism in two widow spider species (family Theridiidae).

The Impact of Terrestrial Oil Pollution on Parasitoid Wasps Associated With Vachellia (Fabales: Fabaceae) Trees in a Desert Ecosystem, Israel.

Oil is a major pollutant of the environment, and terrestrial oil spills frequently occur in desert areas. Although arthropods account for a large share of animal diversity, the effect of oil pollution on this group is rarely documented. We evaluated the effects of oil pollution on parasitoid wasps associated with Vachellia (formerly Acacia) tortilis (Forssk.
