Abstract The prevalence of food insecurity in the USA has increased since the start of the COVID-19 pandemic; however, past studies have not examined how the food security status of college students has been impacted. The purpose of this study was to examine changes in the prevalence of food insecurity; determine the proportion of students experiencing a change in food security status; and identify characteristics associated with changes in food security status from before to during the COVID-19 pandemic among a sample of college students. We administered a cross-sectional online survey to students from a large public university in the Southeastern USA. The 10-item U.S. Adult Food Security Module was used to assess food security status during the spring 2020 semester both before and during the COVID-19 pandemic, and students self-reported a variety of individual characteristics. The overall prevalence of food insecurity increased by approximately one-third during the spring 2020 semester from before to during the COVID-19 pandemic. When examining the types of changes in food security status experienced by students, 12% improved, 68% stayed the same, and 20% worsened. A variety of characteristics were associated with an improvement or worsening of food security status category from before to during the pandemic. Similar to what is seen in other reports, we found that the overall proportion of college students in our sample experiencing food insecurity increased during the COVID-19 pandemic; however, some students showed improvements in food security status. Approaches for addressing food insecurity during and beyond the pandemic are needed.

This article explores the theoretical bases of the Israel-Palestine peace process to see how that impacts peacebuilding and everyday life in Palestine. It begins by examining the lens through which classical and contemporary realist and liberal thought approaches peace, nonpeace, war, and peacebuilding. Second, it examines how knowledge production on peacebuilding has been applied in the Israel-Palestine peace process based on selected confidential documents from the negotiations’ record that was made available in the so-called Palestine Papers published by the Al Jazeera Transparency Unit in 2011. My analysis of this source reveals how an embedded security and market metaphor regulated the Israel-Palestine peace negotiations. I argue that in an ambiguous context of decades-long negotiations, the results are in effect a “buyout” in which security is understood in exclusionary terms by the powerful side.
