Small Town Downtown Revitalization: Applying the Main Street Approach to the towns of Perth and Carleton Place, Ontario

The downtown main street of small towns is traditionally the economic, cultural, and social heart of the community, thereby requiring particular attention from planners and researchers alike. Considering modern threats to main streets including suburban sprawl and "big box" development, revitalization strategies are essential to ensuring longevity and vitality of small towns’ cores, in terms of economy, built environment, heritage, and identity. The Main Street Approach was established to mitigate challenges by providing a revitalization tool-kit for small Canadian towns, focusing on organization, marketing and promotion, economic and commercial development, and design and physical improvements. To better understand existing municipal tools for downtown revitalization in Ontario, a comparative analysis of the towns of Carleton Place and Perth's policies was conducted using the four pillars of the Main Street Approach as benchmark for best practice, and recommendations for other small towns to better incorporate revitalization policies were suggested.

Olhares street art - investigação ação : de que forma abordagens de arte contemporânea nas escolas promovem a criatividade

In this study we intend to address a learning experience that was inspired by the intersection between public art and art education. We intend to make a reflection and analysis of pedagogical actions undertaken during this experience related to a theoretical framework to help us evaluate and improve the pedagogical and methodological strategies. The experience began with a visit to the exhibition "Street Art" at the AXA building in Porto. This visit was made with a group of children of different ages, accompanied by their parents, in May 2014. This exhibition brought new gazes for urban art. By recognizing obvious benefits such as proximity and accessibility, urban art, so rarely addressed in the classroom, may be an educational resource. Our intention in this study asks whether the contact with urban works of art can be motivating for students and facilitators of learning. We used a methodology of action research to approach urban art in visual art education lessons, exploring various art objects of the exhibition "Street Art" and the surrounding city with students. The study findings pointed out a positive response to initial questions

Face Your Fears: Cleaning Gobies Inspect Predators despite Being Stressed by Them

social stressors typically elicit two distinct behavioural responses in vertebrates: an active response (i.e., "fight or flight") or behavioural inhibition (i.e., freezing). Here, we report an interesting exception to this dichotomy in a Caribbean cleaner fish, which interacts with a wide variety of reef fish clients, including predatory species. Cleaning gobies appraise predatory clients as potential threat and become stressed in their presence, as evidenced by their higher cortisol levels when exposed to predatory rather than to non-predatory clients. Nevertheless, cleaning gobies neither flee nor freeze in response to dangerous clients but instead approach predators faster (both in captivity and in the wild), and interact longer with these clients than with non-predatory clients (in the wild). We hypothesise that cleaners interrupt the potentially harmful physiological consequences elicited by predatory clients by becoming increasingly proactive and by reducing the time elapsed between client approach and the start of the interaction process. The activation of a stress response may therefore also be responsible for the longer cleaning service provided by these cleaners to predatory clients in the wild. Future experimental studies may reveal similar patterns in other social vertebrate species when, for instance, individuals approach an opponent for reconciliation after a conflict.
