Geographical Analysis of US Green Sector Industry Concentration
This paper analyzes the geographic distribution of “green energy” sector clustering in the lower 48 United States using recent developments in industry concentration analysis. Evidence suggests that the ten green energy subsectors and the aggregate of the firms comprising the green energy sector are regionally concentrated. Positive changes in industry concentration from 2002 to 2006 tended to be greatest in non-metropolitan counties, suggesting comparative advantage with respect to site location for the composite of firms making up these sectors.Agglomeration, Location Quotient, Renewable Energy, Community/Rural/Urban Development, Industrial Organization, Research and Development/Tech Change/Emerging Technologies,
Supporting Students after a Concussion: School Administrators’ Perspectives
Students with a concussion may experience challenges when returning to school and completing schoolwork. Therefore, students may require temporary academic support throughout the recovery process. The purpose of this study was to examine school administrators’ perceptions of the return to school process and provision of academic adjustments (AA) after concussion. Online surveys were analyzed using a series of descriptive, chi-square, and Mann Whitney tests. School administrators strongly agreed a concussion can affect school performance and were supportive of providing AA for symptomatic students. More school administrators with access to an athletic trainer and who completed concussion training had an established team to monitor concussions and reported students had received AA after concussion. To better prepare school professionals and enhance the support for students after a concussion, school administrators can develop a school-based concussion team, organize in-service training on concussion, and identify pertinent school and district-based resources to facilitate this care
Ponderomotive effects in multiphoton pair production
The Dirac-Heisenberg-Wigner formalism is employed to investigate
electron-positron pair production in cylindrically symmetric but otherwise
spatially inhomogeneous, oscillating electric fields. The oscillation
frequencies are hereby tuned to obtain multiphoton pair production in the
nonperturbative threshold regime. An effective mass as well as a
trajectory-based semi-classical analysis are introduced in order to interpret
the numerical results for the distribution functions as well as for the
particle yields and spectra. The results, including the asymptotic particle
spectra, display clear signatures of ponderomotive forces.Comment: 9 pages, 3 Tables, 3 Figure
A Multifactorial Approach to Sport-Related Concussion Prevention and Education: Application of the Socioecological Framework
To offer an overview of sport-related concussion (SRC) prevention and education strategies in the context of the socioecological framework (SEF). Athletic trainers (ATs) will understand the many factors that interact to influence SRC prevention and the implications of these interactions for effective SRC education
