Secondary Student Perceptions of Vocational Education

The central focus of the present study was to examine the relationship between student personal factors (i.e., gender, race, academic performance, career awareness, and socio-economic factors) and the perceptions of secondary school students regarding vocational education. In recent years, traditional vocational programs have not done well throughout the nation. Enrollment within vocational education has dropped to approximately 10%, while enrollment in college preparation courses has increased to over 50%. The subjects of this study were secondary school students enrolled in the Duval County Public School system. The research was conducted using a two-part survey instrument containing 24 demographic questions and 76 questions related to vocational education. The survey instrument was subjected to content validity analysis by a panel of experts from various universities. Additionally, a validation panel, consisting of 12 vocational education teacher interns, critiqued the instrument. This study was helpful in illuminating the contradictions in commonly held perceptions of vocational educators, guidance counselors, school administrators and political decision makers towards secondary students and their declining interest in vocational education. Five hypotheses were tested relative to the relationship between student personal factors and perceptions of vocational education. The five hypotheses sampled were statistically significant, and R squared values indicate that an appreciable amount of variation in perceptions can be accounted for by student background. Demographic factors are related to students\u27 perceptions of vocational education, with socio-economic status most appreciable among the several predictors

Sublimate: a Kinesthetic Study in the Fear of Death

The intense physical sensations fear presents us with strikes the core of our being to remind us that life is fragile and it can change in an instant. The change from the known to the unknown is felt clearly when we must confront death. The gravity of that unknown impacts our bodily understanding to such a degree that the inevitability of death can dominate conscious and physical attention. Dance offers an ideal arena to examine how the arc of life and death informs our fear and how the inevitability of death is negotiated personally. Through my work, I sought to dismantle the current prevailing notions and fears surrounding death by allowing the audience to encounter its embodiment. Sublimate challenged viewers by investigating the role of spectatorship, disrupting preconceived notions of dance and theory, and physically manifesting fear through movement

An Asian Origin of Virulent Aeromonas Hydrophila Responsible for Disease Epidemics in United States-Farmed Catfish

Unlabelled: Since 2009, catfish farming in the southeastern United States has been severely impacted by a highly virulent and clonal population of Aeromonas hydrophila causing motile Aeromonas septicemia (MAS) in catfish. The possible origin of this newly emerged highly virulent A. hydrophila strain is unknown. In this study, we show using whole-genome sequencing and comparative genomics that A. hydrophila isolates from diseased grass carp in China and catfish in the United States have highly similar genomes. Our phylogenomic analyses suggest that U.S. catfish isolates emerged from A. hydrophila populations of Asian origin. Furthermore, we identified an A. hydrophila strain isolated in 2004 from a diseased catfish in Mississippi, prior to the onset of the major epidemic outbreaks in Alabama starting in 2009, with genomic characteristics that are intermediate between those of the Asian and Alabama fish isolates. Investigation of A. hydrophila strain virulence demonstrated that the isolate from the U.S. catfish epidemic is significantly more virulent to both channel catfish and grass carp than is the Chinese carp isolate. This study implicates the importation of fish or fishery products into the United States as the source of highly virulent A. hydrophila that has caused severe epidemic outbreaks in United States-farmed catfish and further demonstrates the potential for invasive animal species to disseminate bacterial pathogens worldwide. Importance: Catfish aquaculture farming in the southeastern United States has been severely affected by the emergence of virulent Aeromonas hydrophila responsible for epidemic disease outbreaks, resulting in the death of over 10 million pounds of catfish. Because the origin of this newly emerged A. hydrophila strain is unknown, this study used a comparative genomics approach to conduct a phylogenomic analysis of A. hydrophila isolates obtained from the United States and Asia. Our results suggest that the virulent isolates from United States-farmed catfish have a recent common ancestor with A. hydrophila isolates from diseased Asian carp. We have also observed that an Asian carp isolate, like recent U.S. catfish isolates, is virulent in catfish. The results from this study suggest that the highly virulent U.S. epidemic isolates emerged from an Asian source and provide another example of the threat that invasive species pose in the dissemination of bacterial pathogens.

Virulence Factors of Aeromonas hydrophila: In the Wake of Reclassification

The ubiquitous “jack-of-all-trades,” Aeromonas hydrophila, is a freshwater, Gram-negative bacterial pathogen under revision in regard to its phylogenetic and functional affiliation with other aeromonads. While virulence factors are expectedly diverse across A. hydrophila strains and closely related species, our mechanistic knowledge of the vast majority of these factors is based on the molecular characterization of the strains A. hydrophila AH-3 and SSU, which were reclassified as A. piscicola AH-3 in 2009 and A. dhakensis SSU in 2013. Individually, these reclassifications raise important questions involving the applicability of previous research on A. hydrophila virulence mechanisms; however, this issue is exacerbated by a lack of genomic data on other research strains. Collectively, these changes represent a fundamental gap in the literature on A. hydrophila and confirm the necessity of biochemical, molecular, and morphological techniques in the classification of research strains that are used as a foundation for future research. This review revisits what is known about virulence in A. hydrophila and the feasibility of using comparative genomics in light of this phylogenetic revision. Conflicting data between virulence factors, secretion systems, quorum sensing, and their effect on A. hydrophila pathogenicity appears to be an artifact of inappropriate taxonomic comparisons and/or be due to the fact that these properties are strain-specific. This review audits emerging data on dominant virulence factors that are present in both A. dhakensis and A. hydrophila in order to synthesize existing data with the aim of locating where future research is needed

The Kilopixel Array Pathfinder Project (KAPPa), a 16 pixel integrated heterodyne focal plane array

KAPPa (the Kilopixel Array Pathfinder Project) is developing key technologies to enable the construction of heterodyne focal plane arrays in the terahertz frequency regime with ~1000 pixels. The leap to ~1000 pixels requires solutions to several key technological problems before the construction of such a focal plane is possible. The KAPPa project will develop a small (16-pixel) 2D integrated heterodyne focal plane array for the 660 GHz atmospheric window as a technological pathfinder towards future kilopixel heterodyne focal plane arrays

Is Bayh-Dole Good for Developing Countries? Lessons from the US Experience

The US Bayh-Dole Act encourages university patenting of inventions arising from publicly funded research. Lessons from three decades of US experience serve as a cautionary tale for those countries that may choose to emulate Bayh-Dole
