Lunar laser ranging data deposited in the National Space Science Data Center: Filtered observations for September 1969 through June 1970 and unfiltered photon detections for July through December 1970

The technique of laser ranging to a reflector fixed on the lunar surface is discussed. The causes for initial low rate of data acquisition are explained. The documentation to be used in conjunction with the deposition of the filtered data in the National Space Science Data Center are documented. Filtered data obtained during laser operations between the McDonald Observatory and the reflector at Tranquility Base during the interval September 1969 through June 1970 are presented. The unfiltered photon detections for the succeeding six months are examined

Education’s Fiscal Cliff, Real or Perceived?

What would an education fiscal cliff do to public charter school funding, not to mention overall public education funding? And what role, if any, did federal funds play in averting a funding disaster for all public education? This research team currently is looking for answers to these questions. A new research project has been funded to evaluate the revenues provided to traditional public schools and public charter schools during the FY11 school year, and a report on the findings in 30 states and the District of Columbia will be released in spring 2014. Prior to the release of this report, however, we can review data in five cities to see if the alarms matched the reality of school funding

Changes In Submersed Macrophytes In Relation To Tidal Storm Surges

We analyzed long-term submersed macrophyte presence-absence data collected from 15 stations in Kings Bay/Crystal River, Florida in relation to three major storm events. The percent occurrence of most species declined immediately after storm events but the recovery pattern after the storm differed among species. Hydrilla (Hydrilla verticillata (L.F.) Royle)and Eurasian watermilfoil (Myriophyllum spicatum L.) exhibited differing recolonization behaviors. Eurasian watermilfoil recolonized quickly after storms but declined in abundance as hydrilla began to increase in abundance. Natural catastrophic events restructure submersed macrophyte communities by eliminating the dominate species, and allowing revegetation and restructuring of communities. Tidal surges may also act to maintain species diversity in the system. In addition, catastrophic events remove dense nuisance plant growth for several years, altering the public's perception of the nuisance plant problem of Kings Bay/Crystal River

Enhanced light emission from dye doped polymer layers using surface plasmons

We have experimentally verified that the emission of visible light from dye doped polymers can be enhanced with the use of surface plasmon coupling. We have observed an eleven-fold enhancement of light emission

Charter School Funding: Inequity’s Next Frontier

Of all the controversies swirling around the nation’s charter schools, none is more hotly contested than the debate over funding. Charter opponents charge that] these autonomous public schools are draining scarce resources from public school districts. Proponents, by contrast, complain that charter schools do not get their fair share of public education dollars

Online Enlightenment: A Phidget Notification System for Online Status

This paper describes a physical device that presents online presence information in a semi-public space. The device uses a map metaphor to represent a set of connected labs, showing online instant messenger status for members of the community. Device users can combine information from the device with information from the physical environment to identify unfamiliar lab members, determine human-to-human interaction strategies, and plan meetings. The paper reports on design decisions that were considered in creating the device, supplying rationale for decisions that were made. In particular, we focus on how people integrate physical information from the world and virtual information from this (and similar) devices in the environment, reflecting on ways in which this type of device can improve communication and enhance community. We describe four envisioned usage scenarios for the device, with early feedback from people who work in the space and whose information is displayed on the device
