Since de-institutionalization, numerous community based treatment modalities have been implemented to provide treatment for individuals diagnosed as seriously and persistently mentally ill. CTOs are a recent addition to the community mental health care system designed to provide outpatient mental health services to seriously mentally ill clients and using legal mechanisms to enforce a contractual obligation to participate in those services. Although there is a growing body of literature on CTOs and other mandated outpatient treatment programs for people diagnosed with mental illnesses, the research predominantly focuses on the perspectives of service providers and family members. Little attention has been given to how clients view the experience of receiving the treatment and no attention has been given to the experience of clients who are of ethno-racial minority background. As Ontario is a racially and ethnically diverse environment in which many people of minority backgrounds are placed on CTOs. This study, utilizing a phenomenological methodology, interviewed twenty-four participants of ethno-racial minority background who are either on CTOs or have been on a CTO in the past. The focus of the study was to explore the views and lived experience of the participants regarding the treatment. The outcome of the study showed that the participants did not experience the treatment as racially motivated but felt it was necessary and beneficial. The participants discussed the impact of power in the treatment process. Implications of the study were that it would enhance the mental health literature by providing an understanding of serious mental illness among individuals of ethno-racial minority background. The study would provide insight for policy makers and practitioners on providing effective support for the marginalized.

Let X be a unary relation on the domain of (ω,<). The degree spectrum of X on (ω,<) is the set of Turing degrees of the image of X in all computable presentations of (ω,<). Many results are known about the types of degree spectra that are possible for relations forming infinite and coinfinite c.e. sets, high c.e. sets and non-high c.e. sets on the standard copy. We show that if the degree spectrum of X contains the computable degree then its degree spectrum is precisely the set of Δ_2 degrees. The structure ζ can be viewed as a copy of ω* followed by a copy of ω and, for this reason, the degree spectrum of X on ζ can be largely understood from the work on ω. A helpful correspondence between the degree spectra on ω and ζ is presented and the known results for degree spectra on the former structure are extended to analogous results for the latter.

Dimerized antiferromagnetic spin-1/2 chains and ladders demonstrate quantum critical phase transition, the existence or absence of which is dependent on the dimerization and the dimerization pattern of the chain and the ladder, respectively. The gapped phases can not be distinguished by the conventional Landau long-range order parameters. However, they possess non-local topological string order parameters which can be used to classify different phases. We utilize the self-consistent free fermionic approximation and some standard results for exactly solved models to analytically calculate the string order parameters of dimerized spin chains. As a complement parameter the gapped phases possess the topological number, called the winding number and they are characterized by different integer values of the winding number. In order to calculate the string order parameters and winding numbers in dimerized spin chains and two-leg ladders we use analytical methods such as the Jordan-Wigner transformation, mean-field approximation, duality transformations, and some standard results available for the exactly 1D solve models. It is shown that the winding number provides the complementary framework to the string order parameter to characterize the topological gapped phases.
