Strengthening Ontario\u27s System of Housing for People with Serious Mental Illness

This article describes recent work to support recommendations for improving Ontario’s system of housing for people with serious mental illness. This multifaceted project engaged stakeholders in discussions concerning strategies for improving the system based on (a) values that underlie housing programs, (b) evidence of effective housing practices, (c) the current status of the system, and (d) international practices for monitoring community mental health systems. Stakeholders reviewed summaries of the work and discussed implications for improving the provincial system of housing and supports. Recommendations are made for improving the system, focusing on both regional and provincial level actions

Understanding Collaboration as a Dynamic Process: A Case Study of Collaboration in a Supportive Housing Network

Despite considerable research on collaboration, there has been relatively little consideration of the dynamic inter-relations among key characteristics of collaborations. This study examined collaboration within the Ottawa Supportive Housing Network (OSHN). Semi-structured interviews were conducted with members from eight core member agencies that provide supportive housing to a range of vulnerable populations. The interviews examined six categories of effective collaboration characteristics identified in a review by Mattessich and Monsey (1992): environment, membership, process/structure, communication, purpose, and resources. An analysis of the data revealed reciprocal relationships between factors that shifted depending on the nature of the work of the network

Discovery of Seven Companions To Intermediate-Mass Stars With Extreme Mass Ratios in the Scorpius-Centaurus Association

We report the detection of seven low-mass companions to intermediate-mass stars (SpT B/A/F; M similar to 1.5-4.5M(circle dot)) in the Scorpius-Centaurus (Sco-Cen) Association using nonredundant aperture masking interferometry. Our newly detected objects have contrasts Delta L' approximate to 4-6, corresponding to masses as low as similar to 20 M-Jup and mass ratios of q approximate to 0.01-0.08, depending on the assumed age of the target stars. With projected separations rho approximate to 10-30 AU, our aperture masking detections sample an orbital region previously unprobed by conventional adaptive optics imaging of intermediate-mass Sco-Cen stars covering much larger orbital radii (similar to 30-3000 AU). At such orbital separations, these objects resemble higher-mass versions of the directly imaged planetary mass companions to the 10-30 Myr, intermediate-mass stars HR 8799, beta Pictoris, and HD 95086. These newly discovered companions span the brown dwarf desert, and their masses and orbital radii provide a new constraint on models of the Formation of low-mass stellar and substellar companions to intermediate-mass stars.NASA through the Sagan Fellowship ProgramNSF Astronomy and Astrophysics Postdoctoral Fellowship AST-1203023Clay FellowshipNASA through Hubble Fellowship 51257.01AURA, Inc., for NASA NAS 5-26555W.

A Profile of Families in the Emergency Family Homeless Shelter System in Ottawa, Ontario, Canada

Compared to the wealth of research on single homeless adults, there is little known about homeless families. This paper describes a study of 75 homeless families in Ottawa, Ontario, conducted in 2012-2013. This sample of homeless families includes a large number of newcomer families, including immigrants and refugees. Participants are poor and unemployed, but many are educated, and there is little evidence of alcohol or substance abuse. Nonetheless, participants report poor mental health and high levels of family stress. Whereas newcomer families tended to be larger and include more two-parent families than did Canadian-born families, there were no differences in the physical and mental health of the participants. These findings add to our growing understanding of homeless families and point to notable similarities and differences in homeless families in this city in Canada, and in the United States

Far detuned mid-infrared frequency conversion via normal dispersion modulation instability in chalcogenide microwire

We report the observation of modulation instability in the mid-infrared spectral region by pumping a hybrid polymer-chalcogenide optical microwire with a femtosecond optical parametric oscillator operating at 2.6 {\mu}m. It is further shown that this modulation instability occurs in the normal dispersion regime through negative fourth-order dispersion and leads to far detuned parametric frequency conversion at 2 {\mu}m and 3.5 {\mu}m, despite the presence of a strong absorption band around 2.8 {\mu}m. Stochastic nonlinear Schr\"odinger equation simulations of mid-infrared modulation instability are in excellent agreement with experiments

The Science Case for the Planet Formation Imager (PFI)

Among the most fascinating and hotly-debated areas in contemporary astrophysics are the means by which planetary systems are assembled from the large rotating disks of gas and dust which attend a stellar birth. Although important work has already been, and is still being done both in theory and observation, a full understanding of the physics of planet formation can only be achieved by opening observational windows able to directly witness the process in action. The key requirement is then to probe planet-forming systems at the natural spatial scales over which material is being assembled. By definition, this is the so-called Hill Sphere which delineates the region of influence of a gravitating body within its surrounding environment. The Planet Formation Imager project (PFI) has crystallized around this challenging goal: to deliver resolved images of Hill-Sphere-sized structures within candidate planet-hosting disks in the nearest star-forming regions. In this contribution we outline the primary science case of PFI. For this purpose, we briefly review our knowledge about the planet-formation process and discuss recent observational results that have been obtained on the class of transition disks. Spectro-photometric and multi-wavelength interferometric studies of these systems revealed the presence of extended gaps and complex density inhomogeneities that might be triggered by orbiting planets. We present detailed 3-D radiation-hydrodynamic simulations of disks with single and multiple embedded planets, from which we compute synthetic images at near-infrared, mid-infrared, far-infrared, and sub-millimeter wavelengths, enabling a direct comparison of the signatures that are detectable with PFI and complementary facilities such as ALMA. From these simulations, we derive some preliminary specifications that will guide the array design and technology roadmap of the facility.Comment: SPIE Astronomical Telescopes and Instrumentation conference, June 2014, Paper ID 9146-120, 13 pages, 3 Figure
