Bio‐mediated cementation of supratidal beach sediments associated with groundwater springs

open access: yesSedimentology, EarlyView.
ABSTRACT The formation of beachrock, sensu stricto, via carbonate precipitation in the intertidal zone is widespread throughout the tropics and subtropics. While cementation of supratidal beach sediments has also been noted in several locations, it has received much less attention.

An improved criterion for the threshold of motion of sand to gravel‐sized bioclastic carbonate sediments under steady unidirectional flow: Insights from coral skeletal grain experiments

open access: yesSedimentology, EarlyView.
ABSTRACT The threshold of motion of bioclastic carbonate sediments is fundamental to understanding sediment dynamics in coral reef systems, while there are currently few studies on its prediction. In this study, laboratory experiments were conducted on five sediment beds composed of coral skeletal grains coarser than 2 mm, subjected to steady ...

What's Hard Is Yet to Come: Critical Junctures and Changing Gender Beliefs at the Transition From College to Career

open access: yesSociological Forum, EarlyView.
ABSTRACT Drawing on 71 interviews with 20 respondents across four waves before and after their graduation, we explore whether and how the transition from college to career can lead to new experiences with and understandings of gender inequality for elite graduates of color. While all respondents experienced or witnessed gender inequality and recognized

“Through Thick and Thin” How Black Educators Support Urban Students' Postsecondary Plans

open access: yesSociological Inquiry, EarlyView.
How does exposure to Black educators influence minority students' postsecondary planning processes and long‐run educational ambitions? Prior studies have documented positive effects of student‐teacher racial matches on achievement and non‐academic outcomes, but quantitative research designs are often unable to uncover the mechanisms underlying these ...
