Exploring The Use Of Trauma-Informed Care Practices In Extension, Caitlin O'Brien, Martie Gillen Apr 2024

Exploring The Use Of Trauma-Informed Care Practices In Extension, Caitlin O'Brien, Martie Gillen

Journal of Human Sciences and Extension

A content analysis of 63 land-grant Extension university websites was conducted to examine the promotion of trauma-informed care (TIC) through the sharing of resources, providing instructive webinars and/or in-person events, and offering comprehensive programs. While many Extension universities are sharing resources, only nine universities (14%) featured robust TIC Extension programs, and 40% shared no TIC information. Additionally, we found no indication of internal education programs across the universities on adverse childhood experiences (ACEs) and TIC practices for Extension faculty and staff. These findings highlight opportunities to increase efforts with the public as well as internally within Extension.

Reconceptualizing Youth Sparks: A Sociocultural Approach To Co-Designing Programs For Somali Youth, Joanna A. Tzenis Jun 2022

Reconceptualizing Youth Sparks: A Sociocultural Approach To Co-Designing Programs For Somali Youth, Joanna A. Tzenis

Journal of Human Sciences and Extension

The 4-H Youth Development Program has a long history of fostering positive youth outcomes. Recently, attention and resources have been invested in the development of a program model (i.e., the 4-H Thriving Model) that theorizes the program elements that lead to positive outcomes (Arnold, 2018). Less attention, however, has been given to the program design process by which and with whom 4-H programs are designed and implemented. This matters because a lack of a community-engaged design process may lead to outcomes disconnected from community self-interests or to the exclusion of youth who might view the program as irrelevant to their …

Extension’S Response To The Change In Public Value: Considerations For Ensuring Financial Security For The Cooperative Extension System, Jeremy Elliott-Engel, Donna M. Westfall-Rudd, Megan Seibel, Eric Kaufman

Journal of Human Sciences and Extension

Cooperative Extension is a partnership of county, state, and federal governments to fund the translation and community education of applied research from the land-grant university system. Cooperative Extension’s funding since the 1980s has experienced a few key trends such as federal budget stagnation as well as state and county cyclic funding cycles based on the states’ economic health. Accompanying the state-level budget cuts have been calls for Cooperative Extension to reinvent and improve communication about what it does. As budget stability has become a greater concern, ideas around value and return on investment have become more integrated into the messaging …
