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
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
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. Full-resolution versions of

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. Accepted for publication in the
