Objectives: Permanent supportive housing provides safe, stable housing for people with mental and substance use disorders who are homeless or disabled. This article describes permanent supportive housing and reviews research. Methods: Authors reviewed individual studies and literature reviews from 1995 through 2012. Databases surveyed were PubMed, PsycINFO, Applied Social Sciences Index and Abstracts, Sociological Abstracts, Social Services Abstracts, Published International Literature on Traumatic Stress, the Educational Resources Information Center, and the Cumulative Index to Nursing and Allied Health Literature. The authors chose from three levels of evidence (high, moderate, and low) on the basis of benchmarks for the number of studies and quality of their methodology. They also described the evidence of service effectiveness. Results: The level of evidence for permanent supportive housing was graded as moderate. Substantial literature, including seven randomized controlled trials, demonstrated that components of the model reduced homelessness, increased housing tenure, and decreased emergency room visits and hospitalization. Consumers consistently rated this model more positively than other housing models. Methodological flaws limited the ability to draw firm conclusions. Results were stronger for studies that compared permanent supportive housing with treatment as usual or no housing rather than with other models. Conclusions: The moderate level of evidence indicates that permanent supportive housing is promising, but research is needed to clarify the model and determine the most effective elements for various subpopulations. Policy makers should consider including permanent supportive housing as a covered service for individuals with mental and substance use disorders. An evaluation component is needed to continue building its evidence base. Source

This paper deals with mathematical properties of a generic two-fluid flow model commonly used in industrial applications. More precisely, we address the question of whether available mathematical results in the case of a single-fluid governed by the compressible barotropic Navier-Stokes equations may be extended to such a two-phase model. We focus on existence of global weak solutions, linear theory and determination of eigenvalues and invariant regions. © Springer-Verlag 2009. Source

We study some conformally invariant dynamic ways to construct the Conformal Loop Ensembles with simple loops introduced in earlier papers by Sheffield, and by Sheffield and Werner. One outcome is a conformally invariant way to measure a distance of a CLE4 loop to the boundary "within" the CLE4, when one identifies all points of each loop. © 2013 Springer-Verlag Berlin Heidelberg.

Objective: This review assessed the level of evidence and effectiveness of peer support services delivered by individuals in recovery to those with serious mental illnesses or co-occurring mental and substance use disorders. Methods: Authors searched PubMed, PsycINFO, Applied Social Sciences Index and Abstracts, Sociological Abstracts, Social Services Abstracts, Published International Literature on Traumatic Stress, the Educational Resources Information Center, and the Cumulative Index to Nursing and Allied Health Literature for outcome studies of peer support services from 1995 through 2012. They found 20 studies across three service types: peers added to traditional services, peers in existing clinical roles, and peers delivering structured curricula. Authors judged the methodological quality of the studies using three levels of evidence (high, moderate, and low). They also described the evidence of service effectiveness. Results: The level of evidence for each type of peer support service was moderate.Many studies hadmethodological shortcomings, and outcome measures varied. The effectiveness varied by service type. Across the range of methodological rigor, a majority of studies of two service types - peers added and peers delivering curricula - showed some improvement favoring peers. Compared with professional staff, peers were better able to reduce inpatient use and improve a range of recovery outcomes, although one study found a negative impact. Effectiveness of peers in existing clinical roles was mixed. Conclusions: Peer support services have demonstrated many notable outcomes. However, studies that better differentiate the contributions of the peer role and are conducted with greater specificity, consistency, and rigor would strengthen the evidence. Source

Information for a project, including financials and scheduling is stored as the single dataset, with budgeting information automatically integrated to the cash flow information, and with scheduling information automatically integrated to the cash flow information, and vice versa, through the single dataset from a single database to associate scheduled project phases. The single database, allows users to view the cash flow via multiple user interfaces extracted from the same core data, and therefore updates in one user interface can reflect across all user interfaces comprising budget, schedule and cash flow.
