Planned Behavior Typologies of Agricultural Education Teacher Educators Regarding Service Learning as a Method of Instruction: A National Mixed Methods Study

This study sought to understand the service-learning beliefs and intentions of agricultural education teacher educators. We collected quantitative data through a web-based survey instrument and course syllabi. Variables yielding statistically significant relationships were analyzed using cluster analysis, which produced three unique clusters operationalized as typologies representing the planned behaviors of teacher educators regarding service learning. For example, the Optimistically Unaware expressed positive beliefs about the method, but did not understand how to integrate service learning in their teaching methods courses. Meanwhile, the Policy-Focused Decision Makers used established education policy as anchors when navigating decisions, such as whether to feature service learning in their courses. Service-Learning Implementers espoused strong beliefs about the method’s potential while also emphasizing how it could be used to enrich the preparation of agriculture teachers. Results point to the potential service learning holds if integrated as a complement to teacher preparation rather than an addition to current practice

He Rode Alone: Francis Scott Key as an Advocate for Freedom

Recently Francis Scott Key and the Star Spangled Banner have come under increasing historical scrutiny. Claims and allegations of racism and hidden meanings behind the poem have abounded and even led to statues being torn down across the nation. But what is the truth? In reality Francis Scott Key\u27s record on race and slavery is dramatically more complex than the critics would suggest. Indeed, Key spent nearly 40 years of his life advocating in court for the freedom of slaves in Washington DC

Fail-safe system for activity cooled supersonic and hypersonic aircraft

A fail-safe-system concept was studied as an alternative to a redundant active cooling system for supersonic and hypersonic aircraft which use the heat sink of liquid-hydrogen fuel for cooling the aircraft structure. This concept consists of an abort maneuver by the aircraft and a passive thermal protection system (TPS) for the aircraft skin. The abort manuever provides a low-heat-load descent from normal cruise speed to a lower speed at which cooling is unnecessary, and the passive TPS allows the aircraft skin to absorb the abort heat load without exceeding critical skin temperature. On the basis of results obtained, it appears that this fail-safe-system concept warrants further consideration, inasmuch as a fail-safe system could possibly replace a redundant active cooling system with no increase in weight and would offer other potential advantages

A Longitudinal Study of Adolescent Identity Development and Harmful Alcohol Use within a Racially/Ethnically Diverse Sample

The development of a clear sense of identity is a key developmental task in adolescence, and recent studies have found that identity synthesis and confusion are associated negatively and positively, respectively, to alcohol use. One alcohol expectancy - tension reduction - coincides with the hypothesis that identity development may prove to be a stressful developmental process, and may thereby serve as a motivator for adolescents to drink when a belief exists that stress can be reduced through alcohol use. In the present study, we examined the mediational effects between identity synthesis and confusion and later alcohol risk via alcohol expectancies and valuations. The sample included 756 adolescents (53% girls; Mage=13.7 years; SD=1.6 years, 41.4% Hispanic, 39.6% non-Hispanic Black, 8.7% non-Hispanic White, 5.2% Asian, and 5.2% Other). Neither identity synthesis nor confusion significantly predicted tension reduction expectancies. Results indicated that tension reduction expectancies at Time 2 positively predicted alcohol risk levels at Time 3 (β=.112, p=.018). Our findings did not fully support our a-priori hypothesis that identity confusion and identity synthesis later predict tension reduction, in turn predicting alcohol risk. Interestingly, however, the findings revealed that identity synthesis did predict declines in expectancy valuations. This research contributes to the current literature and expounds upon the potential interactions between adolescent identity development and alcohol expectancies and specifically, valuations
