The Other Mobile TV: ATSC MDTV Broadcasting In Canada
    Commentary The Other Mobile TV: ATSC MDTV Broadcasting In Canada
    This commentary describes an approach for delivering television content to mobile phones in Canada using over-the-air broadcast signals. Over-the-air television broadcasting to mobile phones is available to our American neighbours but has not been implemented in Canada. We report on a test of mobile TV services, demonstrating access to U.S. signals from Canada. While it is technically feasible to deliver over-the-air mobile broadcasting in Canada, it is likely that vertical integration in the broadcasting and communications sectors is creating barriers to the development of this service. The commentary concludes with some thoughts on how mobile digital television services could be developed for Canadian viewers., May, S. J., & Middleton, C. (2013, May).

    Commercial Ventures in Nonprofit Organizations: Strategic Change or Natural Evolution?
    Commercial Ventures in Nonprofit Organizations: Strategic Change or Natural Evolution?
    This paper investigates the change processes involved in establishing commercial ventures as revenue generating alternatives in eleven nonprofit organizations, and reports on factors contributing to their success. The eleven cases studied illustrate that the establishment of commercial ventures in nonprofit organizations may result from either deliberate planning or following emergent opportunities. Regardless of whether change was emergent or deliberate, successful organizations were ones that did not try to radically change their paradigms. Their ventures were either merely an extension of existing physical or human resources, or entwined with their mission very early in their life cycle. The unsuccessful and struggling ventures, however, were the result of intended, deliberately planned change strategies that failed because the ventures failed to mesh with the organization’s paradigm.

    Community Support for Newcomer Families: A Literature Review
    Community Support for Newcomer Families: A Literature Review
    As part of a larger study titled “Integration Trajectories of Immigrant Families”, this literature review looked at who provides support for newcomer settlement and integration, and how they are funded. The reviewed studies assessed why support was important, whether the existing supports were sufficient, and what else could be done. Beyond formal and informal support specific to newcomer integration, housing and health were identified as two areas of critical need and as important points of comparison with non-immigrant Canadians. Common across the paper’s three sections on settlement supports, housing, and health were the grey areas pertaining to the service mandates of programs and departments; the coping mechanisms that newcomers and their allies develop to make integration happen; and the barriers to accessing services that include discrimination and differential incorporation. It is recommended that future studies should focus on how different migration pathways affect housing and healthcare needs. They should ask how communities can tailor support to the diverse needs of families, consider how informal community support is leveraged by the government, and examine the ways in which established immigrants facilitate the orientation and integration of more recent newcomer families., Maharaj, S. & Wang, S.

    [Paragraph 1 of Introduction]: Significant shifts have been taking place in Canada’s social philosophy in the last decade or so which are having a major impact on the voluntary sector (McBride and Shields, 1997). These changes in Canada involve decreasing government participation in the provision of the social welfare net that Canadians are used to. At the same time, economic constraints are changing the nature of the partnership between government and the voluntary sector. During the post-war decades there was close cooperation between governments and the voluntary sector, with many government programs encouraging the growth of the sector through the provision of grants; today the government is down loading social services and forcing the sector to seek their funding elsewhere, while encouraging greater reliance on volunteering to provide for social services.

    Comparative Study of DE, PSO and GA for Position Domain PID Controller Tuning
    Comparative Study of DE, PSO and GA for Position Domain PID Controller Tuning
    Gain tuning is very important in order to obtain good performances for a given controller. Contour tracking performance is mainly determined by the selected control gains of a position domain PID controller. In this paper, three popular evolutionary algorithms are utilized to optimize the gains of a position domain PID controller for performance improvement of contour tracking of robotic manipulators. Differential Evolution (DE), Genetic Algorithm (GA), and Particle Swarm Optimization (PSO) are used to determine the optimal gains of the position domain PID controller, and three distinct fitness functions are also used to quantify the contour tracking performance of each solution set. Simulation results show that DE features the highest performance indexes for both linear and nonlinear contour tracking, while PSO is quite efficient for linear contour tracking. Both algorithms performed consistently better than GA that featured premature convergence in all cases., Ouyang, P., & Pano, V. (2015).

    Comparing quantitative and comment-based ratings for recommending open educational resources
    Comparing quantitative and comment-based ratings for recommending open educational resources
    The recent application of recommender systems for educational resources and e-learning has facilitated online and accessible education on social networks. However, there are currently few studies about the methods for evaluation and performance measurement of these recommender systems in the complicated environment of educational and social networking platforms. The purpose of this research paper is to investigate the effectiveness of using sentiment analysis methods for educational resources based on user comments and compare it with the quantitative approach based on user rating to recommend best open learning resources (OER) available through online OER repositories. The quality of the OER will be justified by comparing the user rating and the users' reviews. The quality of users' reviews is based on calculating the term frequency for selected positive and negative terms, then determining the similarity among the comments. Comments with positive or negative words confirm the high and low ratings respectively.

    Comparison of methods to examine the endogenous peptides of fetal calf serum
    Comparison of methods to examine the endogenous peptides of fetal calf serum
    There is a great desire to relate the patterns of endogenous peptides in blood to human disease and drug response. The best practices for the preparation of blood fluids for analysis are not clear and also relatively few of the peptides in blood have been identified by tandem mass spectrometry. We compared a number of sample preparation methods to extract endogenous peptides including C18 reversed phase, precipitation, and ultrafiltration. We examined the results of these sample preparation methods by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) and liquid chromatography-tandem mass spectrometry (MS/MS) using MALDI-TOF/TOF and electrospray ionization-ion trap. Peptides from solid-phase extraction with C18 in the range of hundreds of femtomoles per spot were detected from the equivalent of 1 μL of serum by MALDI-TOF. We observed endogenous serum peptides from fibrinogen α- and β-chain, complement C3, α-2-HS-glycoprotein, albumin, serine (or cysteine) proteinase inhibitor, factor VIII, plasminogen, immunoglobulin, and other abundant blood proteins. However, we also recorded significant MS/MS spectra from tumor necrosis factor-α-, major histocompatibility complex-, and angiotensin-related peptides, as well as peptides from collagens and other low-abundance proteins. Amino acid substitutions were detected and a phosphorylated peptide was also observed. This is the first time the endogenous peptides of fetal serum have been examined by MS and where peptides from low-abundance proteins, phosphopeptides, and amino acid substitutions were detected., Williams, D., Zhu, P., Bowden, P., Stacey, C., McDonell, M., Kowalski, P.. .
