First, it illustrates the direct influence of the music education Pereira …


Commemorating August Thirteenth: Music And Theology In Eighteenth-Century Moravian Communities, Ryan M. Malone Apr 2025

Commemorating August Thirteenth: Music And Theology In Eighteenth-Century Moravian Communities, Ryan M. Malone

Yale Journal of Music & Religion

One of the most important memorial days in the Moravian liturgical calendar is August Thirteenth, a commemoration of the communal spiritual awakening that eighteenth-century Moravians experienced on the Saxon estate of Count Nikolaus Ludwig von Zinzendorf (1700–1760). While the Moravian church has celebrated this storied event for centuries, complete with music-rich religious services, only a few original compositions were crafted specifically for these services. In light of the importance of August Thirteenth, and given of the abundance of musical works that eighteenth-century Moravian composers wrote for other memorial days and religious holidays, this article employs musicological and theological perspectives to …


"Kol Mekadesh Shevi'i": A Liturgical Melody Sung At Home, Naomi Cohn Zentner Apr 2025

"Kol Mekadesh Shevi'i": A Liturgical Melody Sung At Home, Naomi Cohn Zentner

Yale Journal of Music & Religion

This article draws upon the unusual characteristics, origins and prevalence of the melody to the poem "Kol mekadesh shevii" [He who sanctifies the Seventh day] and discusses how it came to be recognized in the past seventy years as a signifier of Ashkenazi pre-Holocaust musical and religious culture and in particular as a sonic marker of liturgical sound, although it was sung at home. The Kol mekadesh melody came over time to represent two vastly different symbolic positions. As a melody adopted from non-Jewish sources bringing new, sometimes controversial sounds into the synagogue, and as a typical synagogal …

Campus Research Month

Despite the availability of a freeway accident dataset collected by Oak Ridge National Laboratory, National Renewable Energy Laboratory, and Tennessee Department of Transportation (TDOT), there is no interactive visualization of the data that is easily accessible to the public. Consequently, the local community's awareness of accident trends is very limited. The contribution of this research project is a dashboard that allows the visualization of traffic accidents patterns in Chattanooga, Tennessee, using datasets from national laboratory researchers. By creating an interactive web dashboard with animated and color-mapped geographical map, the project seeks to enhance community awareness of accident trends.


Mobile Application For Historical Markers*, Kellen Erskine, Harvey Alférez Apr 2025

Mobile Application For Historical Markers*, Kellen Erskine, Harvey Alférez

Campus Research Month

Students find it challenging to engage in their local history solely through in-class instruction. Traditionally, teachers remedy this by organizing field trips. However, field trips can be challenging because they are costly, time-consuming, and a liability to the school. Because of these issues, teachers cannot take the students on as many field trips as they would like. The solution is a web app that allows students to discover the historical sites in their areas. This enables the students to independently visit historical sites and gain the valuable out-of-classroom experience that field trips can help with. The web app was introduced …
