Evaluating the Mentor-Mentee Relationship in the 4-H Tech Wizards Program
Youth rely on mentors to provide camaraderie, encouragement, and guidance. The authors asserted that the measurement of youth-mentor relationship would vastly improve the reaching effects of mentorship and expose areas of potential improvement. A questionnaire was given to youth at the beginning and end of a small group mentoring program. The Mentor-Youth Inventory survey exposed levels of emotional engagement, revealed satisfaction levels, and uncovered the breadth of relationships within the program. The study provides evidence that measuring and establishing a benchmark for the quality of youth-mentor relationships facilitates the opportunity to increase the value of small group mentoring in Extension
Massive Science with VO and Grids
There is a growing need for massive computational resources for the analysis
of new astronomical datasets. To tackle this problem, we present here our first
steps towards marrying two new and emerging technologies; the Virtual
Observatory (e.g, AstroGrid) and the computational grid (e.g. TeraGrid, COSMOS
etc.). We discuss the construction of VOTechBroker, which is a modular software
tool designed to abstract the tasks of submission and management of a large
number of computational jobs to a distributed computer system. The broker will
also interact with the AstroGrid workflow and MySpace environments. We discuss
our planned usages of the VOTechBroker in computing a huge number of n-point
correlation functions from the SDSS data and massive model-fitting of millions
of CMBfast models to WMAP data. We also discuss other applications including
the determination of the XMM Cluster Survey selection function and the
construction of new WMAP maps.Comment: Invited talk at ADASSXV conference published as ASP Conference

Statistical Computations with AstroGrid and the Grid
We outline our first steps towards marrying two new and emerging

Energy and Nutrient Recovery fromCattle Feedlots
Selective harvesting of manure can benefit cattle producers by creating a product of value. A tool that identifies locations of manure accumulation has been developed using a subsurface sensor (Dualem-1S, Milton, ON) and software designed for salt mapping (ESAP, Riverside, CA). The combination allowed the development of models to estimate higher heating value (HHV) of feedlot manure across a feedlot pen. Soil sample data from cattle feedlots in Texas and Nebraska were analyzed for volatile solids (VSs) then combined with the Dualem-1S apparent soil conductivity (ECa) data to produce models having correlations between associated ECa values and VS (r2 = 0.869, VS). A corresponding model is under development to estimate the moisture content of the collectable solids. The combined models allow real-time spatial estimates of HHV within a feedlot pen. These methods will allow direct harvesting of VS for use as a recoverable energy source through direct combustion or cocombustion
Disability Severity, Professional Isolation Perceptions, and Career Outcomes: When Does Leader–Member Exchange Quality Matter?
Employees with disability-related communication impairment often experience isolation from professional connections that can negatively affect their careers. Management research suggests that having lower quality leader relationships can be an obstacle to the development of professional connections for employees with disabilities. However, in this paper we suggest that lower quality leader–member exchange (LMX) relationships may not be a uniform hurdle for the professional isolation of employees with disability-related communication impairment. Drawing on psychological disengagement theory, we predict that employees with more severe, rather than less severe, communication impairment develop resilience to challenges in lower quality LMX relationships by psychologically disengaging from professional connections and, in turn, bear fewer negative consequences of professional isolation on career outcomes. In two studies of deaf and hard of hearing employees, we find that in lower quality LMX relationships employees with more severe communication impairment perceive being less isolated than employees with less severe communication impairment, and, in turn, report better career outcomes. Overall, our findings suggest that employees with more severe communication impairment may develop effective coping strategies to manage challenges of perceived professional isolation for career outcomes when in lower quality LMX relationships
