Food Neophobia And Its Prevalence Among College Students In The United States, Joanne Mwendi Ponnappa Nov 2025

Food Neophobia And Its Prevalence Among College Students In The United States, Joanne Mwendi Ponnappa

Master's Theses

Food neophobia “the reluctance to try unfamiliar foods” may influence diet variety and cultural food acceptance among young adults. College students represent a critical group for studying this behavior, as they are developing independent eating habits that can persist into adulthood. This study examined the prevalence of food neophobia among U.S. college students and evaluated how academic background, travel, cultural exposure, and demographic factors influence openness to trying unfamiliar foods. A cross-sectional online survey was administered via Qualtrics to 264 college students across the United States. The Food Neophobia Scale (FNS; Pliner & Hobden, 1992) was used to assess reluctance …


Rethinking Schedule Quality Risk Assessment, Michael E. Oliver, Patrick T. Rodjom Nov 2025

Rethinking Schedule Quality Risk Assessment, Michael E. Oliver, Patrick T. Rodjom

Beyond the Project Horizon: Journal of the Center for Project Management Innovation

Critical Path Method schedule reliability is dependent on exhibition of specific qualities. Failure to exhibit these qualities (i.e., schedule defects) increases project risk exposure. Although current schedule quality assessment methods provide diagnostic remediation insights, they do not provide a meaningful singular assessment value that characterizes the nature and magnitude of schedule quality risk nor do they enable parity when comparing schedule quality across multiple schedules of disparate size (e.g., number of tasks) or complexity (e.g., number of concurrent paths, degree of merge bias). This study employed a design science research approach to address current schedule quality assessment practice dilemmas through …
