Drone Nation: Policy Considerations for Allowing Commercial Small Unmanned Aircraft Systems Into the National Airspace System

This Comment aims to show that current regulation, or more precisely non-regulation of commercial UAS should be modified, and operators should be allowed to conduct commercial operations without subjecting UAS to the high standards of other “aircraft.” Per Congress’s mandate, the FAA should immediately create and enforce practically sound standards for small-scale, commercial UAS that operate inside the NAS while avoiding unnecessary and costly administrative burdens. Congress should modify the currently voluntary standards, instead of mandating that operators adhere to specific commercial use guidelines without requiring an arduous approval process for commercial flight, such as the current Special Airworthiness Certificate and Section 333 exemption. This Comment will not address the issues facing larger, interstate drones that will operate outside of the visual sight or immediate area of the operator

Nonprofit Georgia: Geography

This pamphlet summarizes statistics on the nonprofit sector in Georgia, assembled and analyzed by a Nonprofit Studies Program research team. The focus of this second report in the "Nonprofit Georgia" series is the geographic distribution of Georgia's nonprofit resources. Numerous tables and exhibits report on the distribution of public charities and foundations by geographic area, and compare this to the distribution of population and income in the state. Public support and government grants to charities are analyzed by geographic region, as is the geographic distribution of grants by Georgia foundations. Analysis is based primarily on 990 and 990-PF forms filed by Georgia public charities and foundations in 2000 and 2005. This report is a part of ongoing research on public charities and foundations in the state of Georgia, made possible through a generous grant from the Wilbur and Hilda Glenn Family Foundation.

Technology development and political and economic power: evolution of global inequality

Abstract Global inequality, in combination with various global problems, has been one of the most pressing concerns of today's world. There are numerous models that explain the development of technology, political and economic power concentration, and resulting social inequality within a single society or region. The models that apply global and long-run perspectives having world-systems as a unit of analysis, however, are rare. This study conducts simulation modeling to examine the formation of hierarchies among polities through the expansion of political economic networks and concentration of power having evolving technologies. Two types of technology-subsistence technologies and technologies of power-have evolved for successful economic and political interactions as well as dominations among polities, resulting in the formation of global hierarchy. The dynamics are modeled and simulated by numerically solving partial differential equations and integro-differential equations that describe polity interactions through trade and warfare networks and selection of advantageous technologies. The validity of the model is examined using city population and state/empire size data since 2000BCE to the present. Models with such a broader perspective allow explanation of the fundamental relationship between technological development

Site Tolerance of the RadA Intein

Inteins (intervening proteins) invade genes at the DNA level and splice out at the protein level. Once thought of as only a parasitic type of a mobile genetic element, recent work suggests a mutualistic relationship has formed in some cases within bacterial and archaeal hosts. After translation, a precursor protein is formed with the intein between two exteins. The intein is catalytic and can excise itself out through protein splicing. Intein insertion is biased towards the active site of the protein and is thought to cause inactivation of the host protein prior to splicing. Intein splicing is responsive to a number of environmental cues, suggesting that conditional protein splicing may serve as a novel form of post-translational regulation. The Pyrococcus horikoshii (Pho) RadA intein will splice in response to substrate single-stranded DNA (ssDNA). Splicing of this protein is inhibited when ssDNA is not present through intein-extein interactions. In this study, the Pho RadA intein was moved from its native position to alternative locations within the RadA sequence. In all alternative positions tested, the intein could no longer splice, even though predictive methods suggest it should. The results provide a greater understanding of intein site selection and point towards a rather complex evolutionary relationship between the intein and its hosts
