CRIMES AND OFFENSES Offenses Against Public Order and Safety: Invasions of Privacy; Wiretapping, Eavesdropping, Surveillance, and Related Offenses

The Act amends the Georgia Code as it relates to the crimes of wiretapping, eavesdropping, and surveillance, by clarifying provisions relating to those crimes; by providing more specifically for violations involving the use of photographic and video equipment; by changing the definition of the term \u27device;\u27 by changing provisions relating to unlawful observation, photographing, and recording of another in a private place; and by making it unlawful for any person to sell, give, or distribute to any person or entity any photograph, videotape, or record of the activities of another which occur in any private place and out of public view without the consent of all persons observed

Detection of Structure in Infrared-Dark Clouds with Spitzer: Characterizing Star Formation in the Molecular Ring

We have conducted a survey of a sample of infrared-dark clouds (IRDCs) with the Spitzer Space Telescope in order to explore their mass distribution. We present a method for tracing mass using dust absorption against the bright Galactic background at 8 microns. The IRDCs in this sample are comprised of tens of clumps, ranging in sizes from 0.02 to 0.3 pc in diameter and masses from 0.5 to a few 10 Msun, the broadest dynamic range in any clump mass spectrum study to date. Structure with this range in scales confirms that IRDCs are the the precursors to stellar clusters in an early phase of fragmentation. Young stars are distributed in the vicinity of the IRDCs, but the clumps are typically not associated with stars and appear pre-stellar in nature. We find an IRDC clump mass spectrum with a slope of 1.76 +/- 0.05 for masses from 30 to 3000 Msun. This slope is consistent with numerous studies, culled from a variety of observational techniques, of massive star formation regions and is close to the mass function of Galactic stellar clusters and star clusters in other galaxies. We assert that the shape of the mass function is an intrinsic and universal feature of massive star formation regions, that are the birth sites of stellar clusters. As these clouds evolve and their constituent clumps fragment, the mass spectrum will steepen and eventually assume the form of the core mass function that is observed locally.Comment: Accepted to ApJ. 37 pages, 24 figures.

Circling the Drain: Regulating Nutrient Pollution from Agricultural Sources

The 2014 Toledo, Ohio tap water ban has, at least temporarily, put a spotlight on United States water supplies. Consequently, many Americans have begun to take a closer look at the quality of the fresh water bodies being used to supply tap water to their homes. Therefore, this Note analyzes the problems currently threatening the lakes, rivers, and other surface waters that are the source of fresh drinking water for huge populations in the United States. Part II examines the problem of nutrient pollution and explains the harmful effects it has on human health. Part III provides an overview of the current laws governing nutrient pollution and tap water quality. Part IV analyzes the source of the problem and demonstrates that agriculture is largely responsible. Lastly, Part V suggests that the problem of nutrient pollution can be resolved through a reinterpretation of the Clean Water Act’s definition of a point source

Luminosity Functions of Spitzer Identified Protostars in Nine Nearby Molecular Clouds

We identify protostars in Spitzer surveys of nine star-forming molecular clouds within 1 kpc: Serpens, Perseus, Ophiuchus, Chamaeleon, Lupus, Taurus, Orion, Cep OB3, and Mon R2, which combined host over 700 protostar candidates. Our diverse cloud sample allows us to compare protostar luminosity functions in these varied environments. We combine photometry from 2MASS J, H, and Ks bands and Spitzer IRAC and MIPS 24 micron bands to create 1 - 24 micron spectral energy distributions (SEDs). Using protostars from the c2d survey with well-determined bolometric luminosities (Lbol), we derive a relationship between Lbol, L_MIR (integrated from 1 - 24 microns), and SED slope. Estimations of Lbol for protostar candidates are combined to create luminosity functions for each cloud. Contamination due to edge-on disks, reddened Class II sources, and galaxies is estimated and removed from the luminosity functions. We find that luminosity functions for high mass star forming clouds peak near 1 Lsun and show a tail extending toward luminosities above 100 Lsun. The luminosity functions of the low mass star forming clouds do not exhibit a common peak, however the combined luminosity function of these regions peaks below 1 Lsun. Finally, we examine the luminosity functions as a function of the local surface density of YSOs. In the Orion molecular cloud, we find a significant difference between the luminosity functions of protostars in regions of high and low stellar density, the former of which is biased toward more luminous sources. This may be the result of primordial mass segregation, although this interpretation is not unique. We compare our luminosity functions to those predicted by models and find that our observed luminosity functions are best matched by models which invoke competitive accretion, although we do not find strong agreement of the high mass star forming clouds with any of the models.Comment: 76 pages, 18 figures, 7 tables.
