    Third Sector Restructuring and the New Contracting Regime: The Case of Immigrant Serving Agencies in Ontario
    Third Sector Restructuring and the New Contracting Regime: The Case of Immigrant Serving Agencies in Ontario
    Many are aware of declining capacity in the NGO sector with respect to advocacy and community development, but to date there has been relatively little analysis of the causes and consequences of this alarming trend. As this paper will demonstrate, however, much more is at work in the service providing sector than simple “overload” due to expansion of service demands beyond available funding. We will document and analyse the ways that the NGO service sector in Canada, and with Ontario based immigrant serving agencies in particular, are being deliberately restructured through the shift from “core” to “program” funding, the de legitimization of community development work as a fundable service, and the imposition of complex and burdensome accountability schemes disguised as evaluation measures. We will also examine the consequences of this restructuring in terms of growing monopolisation within the sector and the consequent reduction of diversity of service alternatives, as well as reduced capacity for public education and community development. The paper will explore the paradox inherent in the fact that such restructuring is being imposed without public debate in the name of the public good, and propose potential solutions related to this crucial issue of Canadian public policy. As essential background to the analysis we will provide an overview of the growing and changing role of the “third sector” as the preferred delivery agent for human services within a downsized and globalized economy.

    Through a lens darkly: how the news media perceive and portray evangelicals
    Studying news is a guarantee against running out of research ideas. Who could have predicted the uproar over the behaviour of a Canadian prime minister at a Catholic funeral for a former Governor General? Perhaps only David Haskell, author of a new book, Through a Lens Darkly: How the News Media Perceive and Portray Evangelicals, that examines how Canadian journalists report on evangelical Christians., Smith, J.

    Throughput Maximization Based on Optimal Access Probabilities in Cognitive Radio System
    Throughput Maximization Based on Optimal Access Probabilities in Cognitive Radio System
    Well-established fact shows that the fixed spectrum allocation policy conveys to the low spectrum utilization. The cognitive radio technique promises to improve the low efficiency. This paper proposes an optimized access strategy combining overlay scheme and underlay scheme for the cognitive radio. We model the service state of the system as a continuous-time Markov model. Based on the service state, the overlay manner or/and the underlay manner is/are used by the secondary users. When the primary user is not transmitting and only one secondary user has the requirement to transmit, the secondary system adopts the overlay scheme. When the primary user is transmitting and the secondary users want to transmit simultaneously, an underlay scheme with an access probability is adopted. We obtain the optimal access probability in a closed form which maximizes the overall system throughput, M. Elalem and L.

    Thunder Bay: Local news is important for conversations on reconciliation
    Thunder Bay: Local news is important for conversations on reconciliation
    [Paragraphs 1 to 3] The Ontario city of Thunder Bay is in the headlines these days for all the wrong reasons. Canada’s highest rates of murder and violent crime. The highest number of hate crimes per capita. Systemic racism embedded in shoddy police investigations. The deaths — many unexplained — of Indigenous students who come to the city for education not available in their remote northern communities. For years these troubles and the inequitable relationship between the Indigenous and non-Indigenous populations in the city festered. Then in the spring of 2011, the Toronto Star began publishing reporter Tanya Talaga’s stories about the deaths of seven young Indigenous students over the previous decade. What had been a local story vaulted into national headlines. Talaga’s reporting became the basis for her 2017 award-winning book Seven Fallen Feathers: Racism, Death and Hard Truths in a Northern City., Lindgren, A. (2019, April 29).

    Time-varying window length for correlation forecasts
    Time-varying window length for correlation forecasts
    Forecasting correlations between stocks and commodities is important for diversification across asset classes and other risk management decisions. Correlation forecasts are affected by model uncertainty, the sources of which can include uncertainty about changing fundamentals and associated parameters (model instability), structural breaks and nonlinearities due, for example, to regime switching. We use approaches that weight historical data according to their predictive content. Specifically, we estimate two alternative models, ‘time-varying weights’ and ‘time-varying window’, in order to maximize the value of past data for forecasting. Our empirical analyses reveal that these approaches provide superior forecasts to several benchmark models for forecasting correlations.

    Timing for delivering individualized patient education intervention to coronary artery bypass graft patients: an RCT
    Timing for delivering individualized patient education intervention to coronary artery bypass graft patients: an RCT
    Background: The primary focus of this study is on the timing of the delivery of education to patients who had CABG surgery. Aim: To determine the efficacy of an individualized telephone patient education intervention, delivered at two different points in time (1–2 days pre-discharge versus 1–2 days post-discharge) in enhancing the CABG patient's knowledge of self-care behaviours, performance of self-care behaviours, and symptom frequency. Method: A randomized clinical trial that included a convenience sample of first time CABG patients. Individuals who received education pre-discharge were compared to individuals who received education post-discharge on the outcomes. Results: Results indicated no statistically significant difference in outcomes between the two time points. As well, anxiety levels were found to be significantly higher in the pre-discharge group than the post-discharge group. Conclusions: The individualized nature of the educational intervention may have accounted for non-significant findings reported in outcomes between the two time points. Practice implications: Nurses may consider assessing anxiety levels prior to delivery of educational interventions, implement interventions aimed at reducing anxiety levels, and provide individualized teaching., Fredericks, S.

    Tools for educators: strategies and ideas for facilitating online group work using project management principles.
    Tools for educators: strategies and ideas for facilitating online group work using project management principles.
    Group work can be used as an effective tool to help students learn from each other, build community and engage with the course content. The key to the success of a group is in the planning and understanding of the purpose of the work needed. The Technology Enhanced Collaborative Group Work (TECGW) indicated through their research on group work that the way in which instructors facilitate a group project has a major impact on the success of the group. Many educators incorporate group work in their courses, but they may not provide the necessary support to students working in these groups; consequently, students get discouraged, and may decline working in groups. In the online learning environments, with the elimination of physical presence, it is necessary to bring students simultaneously to collaborate on various activates of the course to enhance their engagement with each other, the content and the instructor. As technology plays a vital role in online environments, instructors need to develop strategies for students could help them in planning, collaborating and communicating, synchronously and asynchronously, effectively within a group. Project management concepts could effectively be utilized to help in facilitating students' group work. This paper, introduces effective strategies that will help instructors in facilitating group work by providing tools that students could utilize to understand and define their roles in the group. Additionally, the paper will introduce practices in creating group work assignments, supporting students in groups and enhancing communication among students in online environments. The paper provides some practices in using Web 2.0 tools that could facilitate the production of group work, and how these tools could facilitate learning among students working together on face-to-face and online courses.
