Teacher and School Administrator Perceptions of their Learning CommunityMulligan, Donald G. 01 January 2016 (has links)
Charter schools are often characterized as professional learning communities (PLCs). However, researchers have noted the importance of self-reflection of school staff related to their role as a PLC because perceptions can influence the effectiveness of achieving the full implementation of a PLC. The purpose of this quantitative study was to explore the perceptions of teachers and administrators at a large New York school district's 2 charter schools concerning their school site as a learning community. This study was grounded in social constructivist leadership theory in order to analyze a professional learning community as the social unit. Research questions examined differences in responses of all participants (N = 148) between the 5 scales of the School Professional Staff as Learning Community (SPSaLC) questionnaire as well as differences in responses between administrators (n = 30) and teachers (n = 100). A repeated-measures ANOVA indicated significant differences in SPSaLC scale scores (p <.001) with shared vision, addressed needs, and support learning scores significantly higher than democratic and feedback scores. To examine differences in perceptions between teachers and administrators, a MANOVA revealed significant differences (p <.001) indicating that administrators scored shared vision and addresses needs higher than did teachers. The study results may lead to positive social change by providing the local district with initial research findings on the perceptions of school staff related to the 5 major dimensions of a PLC. The district might use these findings to plan for professional development for teachers and administrators to strengthen the implementation of the learning community model at the local site.

Travel time budgets in an urban areaHodges, Fiona Unknown Date (has links) (PDF)
It is important to the future of Melbourne that its development should take the direction of the most benefit to those who live in the city and those who may live here in the future. The current patterns of urban development, which are based on use of previously undeveloped land on the fringes of the suburban area, are now being criticised as being uneconomic in terms of cost of providing infrastructure, the use of natural resources and the waste of time for residents who must travel for long distances.

Contrasting the cases of two cities in Canada : understanding the factors in building confidence in university-city government collaborationsCurry, Joanne January 2015 (has links)
As city governments and universities expand their roles in economic development, an opportunity is created to transform a university–city relationship from an operational one to a strategic one and from co-existence to collaboration. Impacted by history and context, there are many challenges to overcome. The goal of my thesis was to understand the “doing of collaboration” and the specific management processes in university–local government collaborations. I conducted a comparative case study of a Canadian University, Simon Fraser University, and two city governments, Burnaby and Surrey. A number of management processes are critical in building a successful collaboration. Two of the most important are the use of one or more liaison people with the appropriate skills, mandate and access to resources and the involvement of representatives at different organizational levels, particularly faculty who provide access to the university’s research capacity. Bilateral city–university committees and a good relationship between the university president and city mayor are useful but not sufficient to deepen the collaboration. The involvement of third-party organizations in the university–city relationship is beneficial. The importance of trust-building processes such as attribution and dispute resolution are heightened if there is a need to overcome a negative historical incident, an isolated geographic location, or tensions over transactional issues. While management processes are important, a shared strategic goal is paramount. This shared goal may not be evident at the start of a relationship. To identify the shared goal, it is necessary to have an understanding of the most valued university roles given the city’s context and aims. Each organization must have sufficient trust to enter into a deeper collaboration and an initial condition of openness, responsiveness, and commitment is necessary. The thesis provides practical advice to cities and universities and reveals how demonstration of value can build over increasingly ambitious projects.

Seasonal Development of the Biological Control Agent of Dalmatian Toadflax, Mecinus janthiniformis (Curculionidae: Coleoptera), in Utah: Phenology, Overwintering Success, and MortalityWillden, Samantha A. 01 August 2017 (has links)
Invasive weeds are threatening ecosystem function and productivity all over the world by outcompeting desirable vegetation and reducing species diversity. One option for long-term control of such weeds is biological control using natural insect enemies. Such a program has been developed for management of Dalmatian toadflax (Linaria dalmatica (L.) Miller (Plantaginaceae)) in North America using a stem-mining weevil, Mecinus janthiniformis Toševski and Caldara (Coleoptera: Curculionidae). Although widely effective in northern regions, such as in British Columbia and in the American northwest, this insect has been slow to suppress Dalmatian toadflax in southern most regions of their current range, including areas in Utah and Colorado, and little is known of the limiting factors leading to slow weed suppression in these areas.
Using field assessments of insect and plant activity over two growing seasons at several sites, this study aimed to provide degree-day and calendar-date descriptions of insect phenology. In addition, dead, overwintered Dalmatian toadflax stems were dissected to determine overwintering mortality of weevil adults before spring emergence, and living stems were dissected to determine development stages and mortality of weevils during summer development.
Degree-day and calendar-date based models independently resulted in consistent trends in weevil phenology between sites and between years in this study, although the degree-day model is likely to be most useful for purposes of predicting weevil life cycle timing. Interestingly, the sexes differed in their phenology in that males consistently emerged from overwintering sites and were found on Dalmatian toadflax stems considerably earlier than females in the spring. Females as well as males tended to peak in abundance on stems in late-May when Dalmatian toadflax stems reached full maturity.
Overall mortality of M. janthiniformis during a lifecycle was low for all samples; approximately 83% of adults successfully emerged from overwintered stems in the following spring, and greater than 65% of larvae survived to adulthood before overwintering. This resulted in >50% of weevils surviving larval development, overwintering, and spring emergence as adults. The majority of M. janthiniformis deaths (51%) resulted from parasitism by chalcidoid wasps during summer development to adulthood. These parasitoid wasps, and also M. janthiniformis adults, likely created the peculiar exit holes that were observed in live Dalmatian toadflax stems during the summer.
Although M. janthiniformis populations were slow to provide effective control of Dalmatian toadflax at sites in Utah, this study indicates that the phenology and survivorship of M. janthiniformis individuals in Utah are well suited for successful biocontrol. If given enough time to build populations, M. janthiniformis appears to be capable of providing effective Dalmatian toadflax control in southern regions, but other limiting factors, such as precipitation and host plant quality, should be considered in future studies to explain slow weed suppression. Phenology models and estimates of mortality of M. janthiniformis generated by this study at sites in Utah may be helpful in implementing future biocontrol programs of Dalmatian toadflax.

The Effect of a Community of Practice on English Language Development TeachersJanuary 2011 (has links)
abstract: .ABSTRACT The Arizona Department of Education (ADE) empowered a task force to design a new instructional model for English Language Development (ELD) students. The task force created a four-hour, language intensive instructional model which required ELD-indentified students to be immersed in grammar, reading, pre-writing, vocabulary and oral English conversation. This model also mandated a specific number of instructional minutes were to be assigned to each of the model's five components. Moreover, these instructional minutes were to be accounted for by ELD teachers as they developed lesson plans to teach these students. To address the substantial professional development requirements entailed by these mandates, Wenger's Community of Practice (CoP) framework was employed. A CoP was formed to assist nine ELD teachers to (a) meet mandates of the instructional model, (b) participate in professional development opportunities to gain language-based instructional strategies, (c) plan lessons together and eventually, (d) allow them to become more efficacious in their abilities to meet and implement the mandated ADE Sheltered English Instruction (SEI) instructional model developed by the ADE task force. Quantitative and qualitative data were gathered throughout the study by means of a pre- and post-questionnaire, audio taping and transcribing CoP sessions and field notes. Findings suggest the CoP served as an effective forum for increasing ELD teachers' sense of efficacy towards becoming an effective ELD teacher. Moreover, the CoP helped increase understanding of the requirements of the instructional model, participate in professional development specific to their needs and collaborate, which was largely responsible for increasing teacher efficacy. / Dissertation/Thesis / Ed.D.

Truck transport emissions modelCouraud, Amelie 17 September 2007
In the past, transportation related economic analysis has considered agency related costs only. However, transportation managers are moving towards more holistic economic analysis including road user and environmental costs and benefits. In particular, transportation air pollution is causing increasing harm to health and the environment. Transport managers are now considering related emissions in transport economical analyses, and have established strategies to help meet Kyoto Protocol targets, which specified a fifteen percent reduction in Canada's emissions related to 1990 levels within 2008-2012.<p>The objectives of this research are to model heavy vehicle emissions using a emissions computer model which is able to assess various transport applications, and help improve holistic economic transport modeling. Two case studies were evaluated with the model developed.<p>Firstly, the environmental benefits of deploying weigh-in-motion systems at weigh stations to pre-sort heavy vehicles and reduce delays were assessed. The second case study evaluates alternative truck sizes and road upgrades within short heavy oilfield haul in Western Canada. <p>The model developed herein employed a deterministic framework from a sensitivity analysis across independent variables, which identified the most sensitive variables to primary field state conditions. The variables found to be significant included idling time for the weigh-in-motion case study, road stiffness and road grades for the short heavy haul oilfield case study.<p>According to this research, employing WIM at weigh stations would reduce annual Canadian transportation CO<sub>2</sub> emissions by nearly 228 kilo tonnes, or 1.04 percent of the Canadian Kyoto Protocol targets. Regarding direct fuel savings, WIM would save from 90 to 190 million litres of fuel annually, or between $59 and $190 million of direct operating costs.<p>Regarding the short heavy oil haul case study, increasing allowable heavy vehicle sizes while upgrading roads could decrease the annual emissions, the fuel consumption, and their associated costs by an average of 68 percent. Therefore, this could reduce each rural Saskatchewan municipality's annual CO<sub>2</sub> emissions from 13 to 26.7-kilo tonnes, which translates to 0.06 and 0.12 percent of the Canadian Kyoto Protocol targets or between $544,000 and $ 1.1 million annually. <p>Based on these results, the model demonstrates its functionality, and was successfully applied to two typical transportation field state applications. The model generated emissions savings results that appear to be realistic, in terms of potential Kyoto targets, as well as users cost reductions and fuel savings.
