    Program evaluation has the potential to inform and improve youth work practice, as well as help youth sector organizations and initiatives to better understand the impact of their work. This report presents findings from the first province-wide study of the Ontario youth sector's experiences conducting evaluations of their programs and services.This multi-focal study, led by Ontario's Youth Research & Evaluation eXchange (YouthREX), used a Community Dialogue Approach. Grounded in an extensive literature review and drawing on survey and interview data, the report puts forward ten key recommendations for three youth sector stakeholder groups: funders, evaluation capacity builders, and youth sector organizations.The study's contextualized examination of the youth sector's evaluation strengths informs YouthREX's service delivery strategy, and contributes to critical conversations around evaluation-related challenges and opportunities in the youth sector context

    Exposure to a social stressor alters the structure of the intestinal microbiota: Implications for stressorinduced immunomodulation

    a b s t r a c t The bodies of most animals are populated by highly complex and genetically diverse communities of microorganisms. The majority of these microbes reside within the intestines in largely stable but dynamically interactive climax communities that positively interact with their host. Studies from this laboratory have shown that stressor exposure impacts the stability of the microbiota and leads to bacterial translocation. The biological importance of these alterations, however, is not well understood. To determine whether the microbiome contributes to stressor-induced immunoenhancement, mice were exposed to a social stressor called social disruption (SDR), that increases circulating cytokines and primes the innate immune system for enhanced reactivity. Bacterial populations in the cecum were characterized using bacterial tag-encoded FLX amplicon pyrosequencing. Stressor exposure significantly changed the community structure of the microbiota, particularly when the microbiota were assessed immediately after stressor exposure. Most notably, stressor exposure decreased the relative abundance of bacteria in the genus Bacteroides, while increasing the relative abundance of bacteria in the genus Clostridium. The stressor also increased circulating levels of IL-6 and MCP-1, which were significantly correlated with stressorinduced changes to three bacterial genera (i.e., Coprococcus, Pseudobutyrivibrio, and Dorea). In follow up experiments, mice were treated with an antibiotic cocktail to determine whether reducing the microbiota would abrogate the stressor-induced increases in circulating cytokines. Exposure to SDR failed to increase IL-6 and MCP-1 in the antibiotic treated mice. These data show that exposure to SDR significantly affects bacterial populations in the intestines, and remarkably also suggest that the microbiota are necessary for stressor-induced increases in circulating cytokines

    Community indicators: a framework for observing and supporting community activity on Cloudworks

    Cloudworks (Cloudworks.ac.uk) is a social networking site designed for sharing, finding and discussing learning and teaching ideas and experiences. Design and development of the site has been based on an iterative analysis, development and implementation approach, underpinned by ongoing research and evaluation. To this end, we have been seeking to establish strategies to enable us to systematically position transactions and emerging patterns of activity on the site so that we can more reliably use the empirical evidence we have gathered (Galley, 2009a, Galley 2009b, Alevizou et al., 2010a, Conole et al, 2010). In this paper we will introduce a framework we have developed for observing and supporting community development on the site. In building our framework we have used empirical evidence gathered from the site, then related it to the literature from a range of disciplines concerned with professional and learning communities. We link research relating to distance learning communities with studies into Computer Mediated Communication (CMC), self-organising communities on the web, and wider research about the nature of learning organisations and continuous professional development. We argue that this framework can be used to capture the development of productive communities in the space (i.e. how far cohesive, productive groups can be said to be emerging or not) and also help focus futur

    Cloudworks as a ‘pedagogical wrapper’ for LAMS sequences: supporting the sharing of ideas across professional boundaries and facilitating collaborative design, evaluation and critical reflection

    Cloudworks is a specialised social networking site for sharing, debating and co-creating ideas as well as designs and resources for teaching, learning and scholarship in education. The site has been co-funded by JISC and The Open University, and has ca.2500 registered users and visitors from 165 countries (May 2010). Fundamental to the development of the site has been the belief that one of the key challenges in encouraging more innovative learning design is getting teachers to share designs and ideas. Despite the fact that there are numerous repositories of good practice, case studies, learning objects and Open Educational Resources (OER), their impact on practice has been limited (McAndrew and Santos, 2008). Yet in interviews and workshops, when asked what would they find most helpful to enable them to make better use of technologies in their design practices, teachers consistently say that they want examples of good practice and access to others to share and discuss ideas with (Beetham and Sharpe, 2007). This paper will explore how Cloudworks might be used as a ‘pedagogical wrapper’ for LAMS sequences, supporting the sharing of ideas across professional boundaries and facilitating collaborative design, evaluation and critical reflection
