Barriers to recovery and recommendations for change: the Pennsylvania Consensus Conference on psychiatry\u27s role.
OBJECTIVE: Recovery has emerged over the past decade as a dominant theme in public mental health care.
METHODS: The 2006 Pennsylvania Consensus Conference brought together 24 community psychiatrists to explore the barriers they experienced in promoting recovery and their recommendations for change.
RESULTS: Twelve barriers were identified and classified into one of three categories: psychiatry knowledge, roles, and training; the need to transform public mental health systems and services; and environmental barriers to opportunity. Participants made 22 recommendations to address these barriers through changes in policies, programs, and psychiatric knowledge and practice.
CONCLUSIONS: The recommendations identify areas for change that can be accomplished through individual psychiatrist action and organized group efforts
The metallicities of UM151, UM408 and A1228+12 revisited
We present the results of new spectrophotometry and heavy element abundance
determinations for 3 dwarf galaxies UM151, UM408 and A1228+12 (RMB132). These
galaxies have been claimed in the literature to have very low metallicities,
corresponding to log(O/H)+12 < 7.65, that are in the metallicity range of some
candidate local young galaxies. We present higher S/N data for these three
galaxies. UM151 and UM408 have significantly larger metallicities: log(O/H)+12
= 8.5 and 7.93, respectively. For A1228+12 our new log(O/H)+12 = 7.73 is close
to that recalculated from earlier data (7.68). Thus, the rederived
metallicities allow us to remove these objects from the list of galaxies with Z
< 1/20 Z_Sun.Comment: LaTeX, 8 pages with 3 Postscript figures, A&A in pres
Metal Abundances of KISS Galaxies. VI. New Metallicity Relations for the KISS Sample of Star-Forming Galaxies
We present updated metallicity relations for the spectral database of
star-forming galaxies (SFGs) found in the KPNO International Spectroscopic
Survey (KISS). New spectral observations of emission-line galaxies (ELGs)
obtained from a variety of telescope facilities provide oxygen abundance
information. A nearly four-fold increase in the number of KISS objects with
robust metallicities relative to our previous analysis provides for an
empirical abundance calibration to compute self-consistent metallicity
estimates for all SFGs in the sample with adequate spectral data. In addition,
a sophisticated spectral energy distribution (SED) fitting routine has provided
robust calculations of stellar mass. With these new and/or improved galaxy
characteristics, we have developed luminosity-metallicity (-) relations,
mass-metallicity (-) relations, and the so-called Fundamental
Metallicity Relation (FMR) for over 1,450 galaxies from the KISS sample. This
KISS - relation is presented for the first time and demonstrates
markedly lower scatter than the KISS - relation. We find that our
relations agree reasonably well with previous publications, modulo modest
offsets due to differences in the SEL metallicity calibrations used. We
illustrate an important bias present in previous - and -
studies involving direct-method () abundances that may result in
systematically lower slopes in these relations. Our KISS FMR shows consistency
with those found in the literature, albeit with a larger scatter. This is
likely a consequence of the KISS sample being biased toward galaxies with high
levels of activity.Comment: Accepted for publication in The Astronomical Journal; 27 pages, 15

The Star Formation Across Cosmic Time (SFACT) Survey. II. The First Catalog from a New Narrow-Band Survey for Emission-Line Objects
Star Formation Across Cosmic Time (SFACT) is a new narrowband survey designed
to detect faint emission-line galaxies and QSOs over a broad range of
redshifts. Here we present the first list of SFACT candidates from our
pilot-study fields. Using the WIYN 3.5m telescope, we are able to achieve good
image quality with excellent depth and routinely detect ELGs to r = 25.0. The
limiting line flux of the survey is ~1.0 x 10^16 erg/s/cm^2. SFACT targets
three primary emission lines: H-alpha, [O III]5007, and [O II]3727. The
corresponding redshift windows allow for the detection of objects at z ~ 0-1.
With a coverage of 1.50 square degrees in our three pilot-study fields, a total
of 533 SFACT candidates have been detected (355 candidates per square degree).
We detail the process by which these candidates are selected in an efficient
and primarily automated manner, then tabulate accurate coordinates, broadband
photometry, and narrowband fluxes for each source.Comment: 26 pages, 12 figures. Accepted for publication in the Astronomical

Community Participation Among Individuals with Serious Mental Illnesses Leaving Jail
Studies have found that higher levels of community participation are associated with a number of positive outcomes such as increased recovery and quality of life. People with serious mental illnesses (SMI) leaving jail face a number of barriers that limit their ability to participate in community activities. In this paper we examine whether the combined experience of mental illness and recent discharge from jail furthers the community isolation that is already experienced by individuals with serious mental illnesses. This analysis found that people with SMI recently released from jail had significantly lower levels of community participation in terms of overall number of community participation days and activities, number of time spent in activities individuals identified as important, and on measures of sufficiency related to the time spent engaged in these activities. Community participation is a key component of community re-integration for people with SMI leaving jail. The results of this study show that services for people with SMI leaving jail need to include interventions that foster engagement in community based activities
AGC 226067: A possible interacting low-mass system
We present Arecibo, GBT, VLA and WIYN/pODI observations of the ALFALFA source
AGC 226067. Originally identified as an ultra-compact high velocity cloud and
candidate Local Group galaxy, AGC 226067 is spatially and kinematically
coincident with the Virgo cluster, and the identification by multiple groups of
an optical counterpart with no resolved stars supports the interpretation that
this systems lies at the Virgo distance (D=17 Mpc). The combined observations
reveal that the system consists of multiple components: a central HI source
associated with the optical counterpart (AGC 226067), a smaller HI-only
component (AGC 229490), a second optical component (AGC 229491), and extended
low surface brightness HI. Only ~1/4 of the single-dish HI emission is
associated with AGC 226067; as a result, we find M_HI/L_g ~ 6 Msun/Lsun, which
is lower than previous work. At D=17 Mpc, AGC 226067 has an HI mass of 1.5 x
10^7 Msun and L_g = 2.4 x 10^6 Lsun, AGC 229490 (the HI-only component) has
M_HI = 3.6 x 10^6 Msun, and AGC 229491 (the second optical component) has L_g =
3.6 x 10^5 Lsun. The nature of this system of three sources is uncertain: AGC
226067 and AGC 229490 may be connected by an HI bridge, and AGC 229490 and AGC
229491 are separated by only 0.5'. The current data do not resolve the HI in
AGC 229490 and its origin is unclear. We discuss possible scenarios for this
system of objects: an interacting system of dwarf galaxies, accretion of
material onto AGC 226067, or stripping of material from AGC 226067.Comment: Accepted for publication in A&A. 6 pages, 4 figure
HI study of extremely metal-deficient dwarf galaxies. I. The Nancay Radio Telescope observations of twenty-two objects
The goal of this study is to measure parameters of the integrated HI emission
for twenty-two dwarf galaxies with oxygen abundance 12+log(O/H) in the range of
7.42 to 7.65, which are representatives of the eXtremely Metal-Deficient (XMD)
galaxy group. Some of them are expected to be similar to the well-known
candidates for local young galaxies, IZw18 and SBS 0335-052 that have most of
their baryon mass in the form of neutral gas. Therefore, the HI 21-cm line
observations are crucial to understanding their group and individual
properties. The Nancay Radio Telescope (NRT) with the upgraded focal receiver
was used for observations of the 21-cm HI-line. This permitted the detection of
the faintest sources with rms of ~1 mJy per 10.5 km/s resolution element. For
eighteen detected galaxies we present the parameters of their integrated HI
line emission and describe the data on individual objects in more detail. For
four undetected XMD galaxies, we give upper limits on their M$(HI). For 70% of
the twenty studied non low surface brightness XMD galaxies, we find evidence
(both from HI and optical data) for their interaction with neighboring objects.
In the brief discussion of the group HI properties of the observed subsample
(the total O/H range is of 0.23 dex, or a factor of 1.7), we underline the
broad distributions of the HI mass (range is of 2 orders of magnitude), of the
ratio M(HI)/L_B (of 1 order of magnitude), and of the blue luminosity (range is
of 2 orders of magnitude). We also obtained HI parameters of six galaxies that
do not belong to the XMD sample. These data increase the number of XMD galaxies
with known integrated HI parameters (or upper limits) by a factor of two. This
allows us to address statistical properties of this group, which will be
presented in a forthcoming paper. (Abridged).Comment: 11 pages, including 2 tables and 2 postscript figures. Accepted to

Dust Properties and Star-Formation Rates in Star-Forming Dwarf Galaxies
We have used the Spitzer Space Telescope to study the dust properties of a
sample of star-forming dwarf galaxies. The differences in the mid-infrared
spectral energy distributions for these galaxies which, in general, are low
metallicity systems, indicate differences in the physical properties, heating,
and/or distribution of the dust. Specifically, these galaxies have more hot
dust and/or very small grains and less PAH emission than either spiral or
higher luminosity starburst galaxies. As has been shown in previous studies,
there is a gradual decrease in PAH emission as a function of metallicity.
Because much of the energy from star formation in galaxies is re-radiated in
the mid-infrared, star-formation rate indicators based on both line and
continuum measurements in this wavelength range are coming into more common
usage. We show that the variations in the interstellar medium properties of
galaxies in our sample, as measured in the mid-infrared, result in over an
order of magnitude spread in the computed star-formation rates.Comment: 25 pages, 11 figures, 4 tables, ApJ accepte
