An Exploration Into Teachers' Perceptions Of School Leaders' Emotional Intelligence, Lindsey E. Caillouet

LSU New Orleans Theses and Dissertations

Although the benefits of school leader emotional intelligence are well-known, leadership preparation programs lack training in emotional intelligence, thus calling for reform (Darling-Hammond, LaPointe, Meyerson, Orr, & Cohen, 2007; Johnson, Aiken, & Steggerada, 2005; Guerra & Pazet, 2016; Mills, 2009; Wallace, 2010). Emotional intelligence competencies, such as empathy, self-awareness and motivation, are closely aligned with components of transformational leadership theory, including idealized influence, individualized consideration, and inspirational motivation (Kumar, 2014). Highlighting these connections can provide guidance in identifying significant components of emotional intelligence. This study examined teachers’ perceptions of school leaders’ emotional intelligence in order to identify critical components of …

In Response To Totalitarianism: The Hawkish Cold War Foreign Diplomacy Of The Europeans Kissinger And Brzezinski During American Détente, D'Otta M. Sniezak

LSU New Orleans Theses and Dissertations

Despite historians describing the 1970s as a time of détente, both National Security Advisors that dominated America’s foreign policy pursued harsh stances against the Soviet Union. Henry Kissinger and Zbigniew Brzezinski sabotaged peace talks in order help the United States keep its edge against the other world superpower. Most historians point to the similarities between these two men, but what is most often left out of the narrative is that both men witnessed persecution at the hands of totalitarian governments: Kissinger by the Nazis and Brzezinski by both the Nazis and the Soviets. This influence is strong in their first …

Prenatal Risk For Autism Spectrum Disorder (Asd): Fetal Cortisol Exposure Predicts Child Asd Symptoms, Sheena Ram, Mariann A. Howland, Curt A. Sandman, Elyssia Poggi Davis, Laura M. Glynn

Psychology Faculty Articles and Research

The etiology of autism spectrum disorder (ASD) is multifactorial, complex, and likely involves interactions among genetic, epigenetic, and environmental factors. With respect to environmental influences, a growing literature implicates intrauterine experiences in the origin of this pervasive developmental disorder. In this prospective longitudinal study, we examined the hypothesis that fetal exposure to maternal cortisol may confer ASD risk. In addition, because ASD is four times more prevalent in males than in females, and because sexually dimorphic responses to intrauterine experiences are commonly observed, we examined whether or not any associations differ by fetal sex. Maternal plasma cortisol was measured at …
