Religion is a complex and sociocultural driver of human papillomavirus (HPV) vaccination decisions, but its exact role has been mixed/unclear. We used a cross-sectional study of 342 Christian parents to examine the associations between the three domains of religiosity (organizational, non-organizational, and intrinsic) and the intention to (i) seek HPV information and (ii) receive the HPV vaccine. Organizational religiosity was the only domain that was positively associated with information-seeking intention regardless of the type of covariates included. Mixed findings in the association between religiosity and HPV vaccination decisions may depend on the religiosity domain being assessed.

Faculty Publications

Chronic kidney disease is a progressive, incurable condition that involves a gradual loss of kidney function. While there are no non-invasive biomarkers available to determine whether individuals are susceptible to developing chronic kidney disease, small RNAs within urinary exosomes have recently emerged as a potential candidate to use for assessing renal function. Ultracentrifugation is the gold standard for urinary exosome isolation. However, extravesicular small RNA contamination can occur when isolating exosomes from biological fluids using ultracentrifugation, which may lead to misidentifying the presence of certain small RNA species in human urinary exosomes. Therefore, we characterized human urinary exosomal preparations isolated …

How Capuchin Monkeys Use Their Semi-Prehensile Tails, Madhur Mangalam, Callum F. Ross, Patricia Izar, Elisabetta Visalberghi, Dorothy M. Fragaszy

Journal Articles

Among primates, prehensile/semi-prehensile tails have evolved independently in the families Atelidae and Cebidae of the infraorder Platyrrhini (Neotropical monkeys). They facilitate maintaining stability during locomotion on thin, flexible branches and while reaching for food on challenging substrates. How a prehensile/semi-prehensile tail is coordinated with the hind limbs to facilitate controlled, flexible adoption of postures remains unknown. In an experimental set-up in the wild, we induced capuchin monkeys to adopt a tail-assisted, head-down tripodal posture to reach for food, documenting from slow-motion video recordings (120 fps) both qualitative changes in the monkeys’ positional behaviour – the relative orientation of their limbs …
