(Special Section, Hymns Beyond The Congregation Ii): Whither Christian Soldiers? Metaphor And Momentum In The Midtwentieth-Century Reception Of A Victorian Hymn, Jonathan Hicks

Yale Journal of Music & Religion

There are few more explicit documents of the interconnection of hymnody, mobility, and coloniality than the 1939 film Stanley and Livingstone. Directed by the American duo of Henry King and Otto Brower, much of the picture was filmed “on location” in the British-controlled territories of Kenya, Uganda, and Tanganyika (now part of Tanzania). The film tells the real-life story of a New York journalist (Stanley) searching for a Scottish missionary (Livingstone) and eventually finding him in a town on the north-eastern shore of Lake Tanganyika. One scene in particular—where Stanley finds Livingstone leading his hosts in a rendition of …

(Special Section, Hymns Beyond The Congregation Ii): “We’Ll Understand It Better By And By:” Nomenclature, Negotiation, And Naming Our Neighbors, Emmett G. Price Iii

Yale Journal of Music & Religion

Hymns, whether composed for religious contexts or as expressions of spiritual reflection, are historically revered for their redemptive nature. For generations, Black Hymnody has cried out for Christological interventions to end shambolic and systemic oppression against Black people. The vicious murder of George Perry Floyd, Jr. on May 25, 2020 reverberated and initiated, as a catalyst, an overdue global awakening that sparked a catalytic moment for conversations too long deferred. Conversations that question how we experience and name things; how we negotiate trauma; and how we engage one another as neighbors. In many ways, the redemptive nature of hymns has …

Exploring Teacher Leadership’S Effect On Teacher Burnout: Does School Rurality Make A Difference?, Jiangang Xia, Sam Butler

Department of Teaching, Learning, and Teacher Education: Faculty Publications

In literature, both teacher leadership and teacher burnout have been heavily studied. However, it is unknown to what extent teacher leadership makes a difference in teacher burnout, and whether school rurality makes a difference in between. This study fills the research gaps by conceptualising teacher leadership from both instructional and non-instructional dimensions and applying a quantitative method to large-scale national data. Findings revealed that (a) rural teachers presented higher levels of teacher leadership practices; (b) rural and non-rural teachers presented the same levels of burnout; and (c) both instructional and noninstructional dimensions of teacher leadership practices helped reduce teacher burnout …
