The objective of the experimentation was to explore the effect of crosslinker chain length on the morphology of nanofiber mats. Specifically, poly(vinyl alcohol (PVA) was electrospun into nanofiber mats and poly(ethylene) glycol bis(carboxylic acid) (PEG diacid) was used as the crosslinking agent. As-spun fibers had average fiber diameter of 70 ± 30 nm with an average pore size of 0.10 ± 0.16 μm^2. The fiber diameter for the mats crosslinked with the shorter PEG diacid (Mn = 250) increased to 110 ± 40 nm with an average pore size of 0.11 ± 0.04 μm^2. The mats crosslinked with the longer PEG diacid (Mn = 600) had fiber diameters of 180 ± 10 nm with an average pore size 0.01 ± 0.02 μm^2.
A growing body of research suggests a link between adverse childhood experiences and negative health outcomes. However, less is known about where racial discrimination ranks compared to other adverse childhood experiences, such as maltreatment. To address this issue, I conducted two systematic reviews of meta-analyses to compare the magnitudes of the links between racial discrimination and depressive symptoms and childhood maltreatment and depressive symptoms. My aim was to establish if racial discrimination should be considered an adverse childhood experience. My results demonstrated that the link between racial discrimination and depressive symptoms (r = 0.27) is comparable to the links between 4 different manifestations of maltreatment and depressive symptoms (physical abuse: r = 0.257, emotional abuse: r = 0.301, neglect: r = 0.381, sexual abuse: r = 0.408). I discuss the implications of these findings and propose future research directions.
