The Influence Of Transformational Leadership, Achievement Motivation, And Organizational Culture On Teachers’ Learning Innovation: A Quantitative Study In Public Senior High Schools, Dewi Nur Cahyaningrum, Yovitha Yulijantiningsih, Supriyono Supriyono

Journal of ICSAR

This study analyzes the influence of transformational leadership, achievement motivation, and organizational culture on teachers’ learning innovation in public senior high schools in Jepara Regency. Using a quantitative survey involving 215 teachers, multiple regression analysis was employed to examine both partial and simultaneous effects. The results show that transformational leadership (β = 0.421; p < 0.001), achievement motivation (β = 0.367; p < 0.001), and organizational culture (β = 0.298; p < 0.001) significantly affect teachers’ learning innovation. Collectively, the three variables explain a substantial proportion of variance in learning innovation (R² = 0.612). In this study, learning innovation is defined to include inclusive teaching practices, the use of accessible digital tools, differentiated instruction, and adaptive strategies that support students with diverse learning needs, including those with disabilities. The findings therefore highlight that pedagogical innovation does not only involve creativity and technology integration but also the development of equitable and disability-responsive learning environments. The study underscores that inclusive learning innovation emerges from the synergy of strong transformational leadership, high teacher motivation, and a school culture committed to accessibility and collaboration. These findings provide important implications for educational leaders and policymakers, calling for the strengthening of inclusive leadership capacity, the cultivation of disability-sensitive school cultures, and the enhancement of teacher motivation to promote equitable instructional reform.

Department of Surgery Faculty Papers

Introduction: Hemiarch replacement with proximal aortic replacement is seldom performed via upper hemisternotomy (UHS). We report our surgical technique and postoperative outcomes in 11 patients who underwent UHS for hemiarch and proximal aortic replacement, compared with 15 patients who underwent the procedure via full sternotomy (FS).

Methods: A UHS was performed at the right third or fourth intercostal space. Cardiopulmonary bypass (CPB) was established via the distal ascending aorta or right axillary artery and right common femoral vein. After aortic cross-clamping (ACC), the heart was arrested with single-dose antegrade crystalloid cardioplegia. After proximal aortic replacement, hypothermic circulatory arrest (HCA) between …

Unconstrained Plasticity Disrupts Memory Consolidation In A Mouse Model Of Rett Syndrome, Huda Y Zoghbi, Sachin P Vaidya

Faculty, Staff and Students Publications

Memory impairment is a hallmark cognitive deficit in Rett syndrome (RTT). Yet, long-term memory deficits in RTT animal models remain poorly understood, largely due to the technical challenges inherent in tracking neural activity over extended periods. Here, we used longitudinal two-photon calcium imaging to follow the same population of hippocampal CA1 neurons as RTT mice and their littermate controls formed cognitive maps of their environment during a spatial learning task. Neural representations in RTT mice were marked by excessive place cell (PC) activity, with individual PCs exhibiting pronounced instability across days. This disrupted single-cell stability propagated to the population level, …
