Birthing Alone, Elizabeth Kukura

Washington and Lee Law Review

Throughout the COVID-19 pandemic, hospitals implemented restrictive visitor policies that have prevented many pregnant people from giving birth with their chosen support people. For some, this meant foregoing labor and delivery support by a birth doula, someone who serves in a nonclinical role and provides emotional, physical, and informational support to birthing people. Given that continuous labor support such as the care provided by doulas is associated with fewer cesareans and other interventions, less need for pain medication, and shorter labors, the promotion of doula care is a promising strategy to ease the maternal health crisis and, in particular, shrink …

Belonging In Context: An Exploration Of Sense Of Belonging Among College Students, Ladonna L. Gleason

Theses and Dissertations

Feeling a sense of belonging is essential to human health and functioning and has been well documented in the literature. However, questions of context remain. Research in belonging has focused on social aspects of belonging, leaving broader contextual frames unexplored. There has been little work in identifying and differentiating the contexts in which belonging is experienced or in developing an understanding of how the experience of belonging differs across contexts. Current belonging theory lacks this important contextual perspective that could inform the ways in which belonging is constructed and reconstructed through disruption. With the advent of the COVID-19 pandemic, new …
