Boosting Upward Mobility: A Planning Guide for Local Action
Are you a member of local government who wants to increase upward mobility in your community? If so, this guide can help you better understand impediments to upward mobility and build a cross-sector team that can plan, advocate for, and implement a set of systems changes focused on bringing all members of your community out of poverty and creating more equitable results.We developed this guide with you—the user—in mind. It provides practical advice for people driven to boost mobility from poverty and asking, "Where do I start?" More specifically, this guide is intended for city and county government leaders who can plan, advocate for, and implement a set of policy and program changes—informed by the Mobility Metrics (explained in the next section)—that are focused on boosting mobility from poverty
Lidar measurements of stratospheric ozone at Table Mountain, California, since 1988
Regular measurements of stratospheric ozone concentration profiles have been made at Table Mountain, California, since January 1988. During the period to December 1991, 435 independent profiles were measured by the differential absorption lidar technique. These long-term results, and an evaluation of their quality, is presented in this paper

Globalization, Fisheries and Recovery
This project looks at fisheries and fishing-dependent communities of western Newfoundland in the context of broader regional and globalization processes,
especially those affecting labour markets and markets for fish products. We hope to answer several inter-related questions: 1) How is the fishing industry functioning in the post-moratorium period and what are its future prospects? 2) How can we best understand the current situation of, and prospects for, communities that have been dependent on the fishery? 3) How have they adjusted to the collapse of the groundfish fisheries? 4) What new opportunities are being pursued and what challenges exist, particularly in terms of labour and markets? In the course of our research, we also found evidence of social and cultural change in these communities, which we will take into account as we address the core questions
Genetic mixed stock analysis of an interceptory Atlantic salmonfishery in the Northwest Atlantic
Interceptory fisheries represent an ongoing threat to migratory fish stocks particularly when managed in the absence of stock specific catch and exploitation information. Atlantic salmon from the southern portion of the North American range may be subject to exploitation in the commercial and recreational salmon fisheries occurring in the French territorial waters surrounding St. Pierre and Miquelon off southern Newfoundland. We evaluated stock composition of Atlantic salmon harvested in the St. Pierreand Miquelon Atlantic salmon fishery using genetic mixture analysis and individual assignment with a microsatellite baseline (15 loci, 12,409 individuals, 12 regional groups) encompassing the species western Atlantic range. Individual salmon were sampled from the St. Pierre and Miquelon fishery over four years (2004, 2011, 2013, and 2014). Biological characteristics indicate significant variation among years in the size and age distribution. Nonetheless, estimates of stock composition of the samples showed consistent dominance of three regions (i.e., Southern Gulf of St. Lawrence, Gaspe Peninsula, and New-foundland). Together salmon from these regions accounted for more than 70% of annual harvest over the decade examined. Comparison of individual assignments and biological characteristics revealed a trend of declining fresh water age with latitude of assigned region. Moreover, locally harvested Newfoundland salmon were ten times more likely to be small or one sea winter individuals whereas Quebec and Gaspe Peninsula salmon were two-three times more likely to be harvested as large or two sea winter salmon.Estimates of region specific catch were highest for salmon from the southern Gulf of St. Lawrence region ranging from 242 to 887 individuals annually. This work illustrates how genetic analysis of interceptory marine fisheries can directly inform assessment and management efforts in highly migratory marines pecies
The Wide-field Infrared Survey Explorer (WISE): Mission Description and Initial On-orbit Performance
The all sky surveys done by the Palomar Observatory Schmidt, the European
Southern Observatory Schmidt, and the United Kingdom Schmidt, the InfraRed
Astronomical Satellite and the 2 Micron All Sky Survey have proven to be
extremely useful tools for astronomy with value that lasts for decades. The
Wide-field Infrared Survey Explorer is mapping the whole sky following its
launch on 14 December 2009. WISE began surveying the sky on 14 Jan 2010 and
completed its first full coverage of the sky on July 17. The survey will
continue to cover the sky a second time until the cryogen is exhausted
(anticipated in November 2010). WISE is achieving 5 sigma point source
sensitivities better than 0.08, 0.11, 1 and 6 mJy in unconfused regions on the
ecliptic in bands centered at wavelengths of 3.4, 4.6, 12 and 22 microns.
Sensitivity improves toward the ecliptic poles due to denser coverage and lower
zodiacal background. The angular resolution is 6.1, 6.4, 6.5 and 12.0
arc-seconds at 3.4, 4.6, 12 and 22 microns, and the astrometric precision for
high SNR sources is better than 0.15 arc-seconds.Comment: 22 pages with 19 included figures. Updated to better match the

The Arecibo Legacy Fast ALFA Survey: III. HI Source Catalog of the Northern Virgo Cluster Region
We present the first installment of HI sources extracted from the Arecibo
Legacy Fast ALFA (ALFALFA) extragalactic survey, initiated in 2005. Sources
have been extracted from 3-D spectral data cubes and then examined
interactively to yield global HI parameters. A total of 730 HI detections are
catalogued within the solid angle 11h44m < R.A.(J2000) < 14h00m and +12deg <
Dec.(J2000) < +16deg, and redshift range -1600 \kms < cz < 18000 \kms. In
comparison, the HI Parkes All-Sky Survey (HIPASS) detected 40 HI signals in the
same region. Optical counterparts are assigned via examination of digital
optical imaging databases. ALFALFA HI detections are reported for three
distinct classes of signals: (a) detections, typically with S/N > 6.5; (b) high
velocity clouds in the Milky Way or its periphery; and (c) signals of lower S/N
(to ~ 4.5) which coincide spatially with an optical object of known similar
redshift. Although this region of the sky has been heavily surveyed by previous
targeted observations based on optical flux-- or size-- limited samples, 69% of
the extracted sources are newly reported HI detections. The resultant
positional accuracy of HI sources is 20" (median). The median redshift of the
sample is ~7000 \kms and its distribution reflects the known local large scale
structure including the Virgo cluster. Several extended HI features are found
in the vicinity of the Virgo cluster. A small percentage (6%) of HI detections
have no identifiable optical counterpart, more than half of which are high
velocity clouds in the Milky Way vicinity; the remaining 17 objects do not
appear connected to or associated with any known galaxy.Comment: Astronomical Journal, in pres
Misinformation as Immigration Control
It is wrong to force refugees to return to the countries they fled from. It is similarly wrong, many argue, to force migrants back to countries with life-threatening conditions. I argue that it is additionally wrong to help such refugees and migrants voluntarily return whilst failing to inform them of the risks. Drawing on existing data, and original data from East Africa, I describe distinct types of cases where such a wrong arises. In ‘Misinformation Cases’ officials tell refugees that it is safe to return, when it is not, and refugees return who would have otherwise stayed. In ‘Omission Cases’ officials do not provide any information on countries of origin, and this omission causes refugees to repatriate. In ‘Relevancy Cases’ refugees are misinformed or uninformed, but would have returned even if better informed. In all of these cases, at least some state officials are blameworthy for their failure to inform refugees, and are engaging in a form of wrongful immigration control
