Arctic Field Equipment

Reports designs of equipment developed since 1959 for the Defence Research Establishment Pacific of the Defence Research Board of Canada, making underwater acoustic measurements on the sea ice in Canadian Arctic Islands waters. A triangular ice drill tip, and an inflatable plug to prevent transducers from being trapped below the ice by refreezing of the holes are described, as is with illus a recovery method for underwater equipment which is unattended for several months, the so-called rope trick. The last is an open-ended cylinder wrapped with nylon rope embedded in a silicon rubber having a low tensile strength. An aluminum sled with four rather than two runners reduces slamming by conforming to the ice roughness. A 7 x 4 x 1 ft, 100 lb emergency shelter termed instant igloo includes a kerosene-fired stove and a fiberglass-and-foam-plastic sandwich floor. A large main shelter and its heating and snow meltwater systems are also described.Équipement de terrain dans l'Arctique. L'équipement décrit ici permet aux "scientifiques de fauteuil" de travailler et de vivre confortablement lors d'expéditions hivernales dans l'Arctique. Il comprend des méthodes de déposition et de récupération de sondes à travers la glace de mer, l'étude d'un traineau à marchandises et l'étude d'abris de toile légers et confortables

Representation and Public Engagement: A Study of the Experience of Non-Profit Leaders as Representatives of the Communities They Serve

Public engagement has recently become increasingly important to local governments. Public engagement provides opportunities for relationship development and better informed and supported decision-making and policy development. To create better decisions and more informed policies, governments aim to hear from many populace segments, including underserved and marginalized communities. As part of public engagement, non-profit organizations and non-profit leaders are invited representatives for the clients and communities they serve. This research aimed to examine the role of non-profit leaders' representation. Specifically, the study looked at representation by examining the experiences of leaders of non-profit social service organizations who participate in public engagement in Edmonton, Alberta, on behalf of the clientele they serve. Using a grounded approach, the research develops an understanding of how non-profit leaders comprehend and perform their role as representatives. Semi-structured, in-depth interviews were conducted with five participants, all leaders in the non-profit sector in Edmonton, Alberta. Three key themes emerged from the interview data: standing in place, giving voice and providing protection. These three themes are further broken into subthemes that help understand how non-profit leaders experience, understand and feel about their role as representatives for marginalized communities in public engagement activities

An Ice Drift Measurement in Western Parry Channel

A description is given of the drift of ice in Western Parry Channel during the spring and summer of 1970. Ice-buoys, planted in the fast ice of this region in April 1970, were located at approximately two-week intervals by Canadian Forces aircraft overflights. The ice in M'Clure Strait drifted to the west, whereas in Viscount Melville Sound the ice drift seemed to have no definite trend. The drift after the middle of July, when the ice was broken was compared to the ice motion calculated using Zubov's rule. The comparison yields a respectable agreement. Also, information pertaining to the longevity of ice-buoys in both polar and winter ice is given

Cauldron of Forces: Designing a Lightning Observatory on Lake Maracaibo

There are storms in the world, and the world is a storm, and we ourselves are weather. Earth and the universe are continually emerging and dissolving: geological, meteorological, and biological forces interact to create planets, storms, and living creatures, which cycle from one form to another. What seems static is simply moving slowly. Everything is weather. As an example, take the Maracaibo Basin in western Venezuela, a 50,000 km² valley where wind, water, oil, and mountains are fused in a single turbulent system. The Catatumbo Lightning burns overhead, dominating the scene. Nearly every night for centuries there has been a thunderstorm over Lake Maracaibo – a persistent, recurring weatherform that has shaped cultural memory and mythology in the region. Below, the lake is the centre of Venezuela’s oil extraction operation. Wellheads dot the surface of the lake, threaded by a labyrinth of leaky underwater pipelines. All these phenomena have their genesis in the geological processes that shaped the basin. The uplift of surrounding mountain ranges has depressed the valley, freeing deep reservoirs of oil and trapping them close to the surface. The same mountains funnel low-level winds sweeping south from the Caribbean and create favourable conditions for thunderstorms. This thesis wrestles with the complexity of the Maracaibo Basin through storytelling and design. Part One is a cosmic history, tracking the spatial and cultural metamorphosis of the valley. Part Two is a design investigation into architecture’s capacity to frame an encounter with wild weather. Through the speculative design of a thunderstorm observatory sited near the epicentre of the Catatumbo Lightning, it asks: what kind of architecture might participate in cycles of transience and change, rather than obscuring them? How might architecture extend sensory perception and become an instrument for connecting humans more completely to the storm that is our world

Cathleen McCarthy

In 1920, a thirty-year-old woman named Cathleen McCarthy got a job as a reporter at The Peterborough Examiner. As the only woman reporter on staff, she quickly found herself in charge of the “Women’s Page” and its “society” and fashion features. Within a year or so, however, she was also writing film reviews—and would continue on that beat until she left the paper in 1937. McCarthy was not only the first film critic in Peterborough, but also one of a very few in Canada

Grief and loss lives in schools : Chetwynd Secondary School : a case study

xi, 119 leaves ; 29 cm. --Grief and loss has an impact on students in schools. This project combines qualitative and quantitative research into an action research case study. A small high school in northern British Columbia is the location of the project. Areas ofliterature research include: models of grief and loss, models of grief and loss specifically for adolescents and children, grief and loss (death) education, support groups, helping relationships, grief and loss teams, community building in schools, and the sharing of craft knowledge. Data collection techniques include: interviews with students and teachers following interview blueprints, two focussed discussions with different classes, and exit slips. Data analysis uses a three-phased coding process. Three main themes from data collection are: grief and loss, support systems and relationships, and future directions and personal/professional growth. Some of the findings show: a difference in the ways that teenage boys and girls deal with grief and loss, ideas for implementation of grief and loss education for students and teachers, student concerns about support groups, and validation that community building in schools is essential. Grief and loss lives in schools, it is time that all schools do something to acknowledge the needs of grieving youth, and communicate with youth to find out the students individual needs while grieving

Iodide-Catalyzed Ring-Opening Cyclization of Cyclohexane-1,3-dione-2-spirocyclopropanes

The ring-opening cyclization of 2\u27,3\u27-nonsubstituted and 2\u27-electron-withdrawing group (EWG)-substituted cyclohexane-1,3-dione-2-spirocyclopropanes was accomplished using iodide as a catalyst. The nonsubstituted derivatives afforded 3,5,6,7-tetrahydro-1-benzofuran-4(2H)-ones in high yields in the presence of trimethylsilyl iodide at room temperature. The EWG-substituted spirocyclopropanes, in turn, underwent regioselective ring opening followed by cyclization, which gave rise to 2-substituted tetrahydrobenzofuran-4-ones when a combination of tetrabutylammonium iodide catalyst and trifluoromethanesulfonic acid was used, whereas calcium iodide afforded the 3-substituted derivatives

An Efficient Route to Highly Substituted Indoles via Tetrahydroindol-4(5H)-one Intermediates Produced by Ring-Opening Cyclization of Spirocyclopropanes with Amines

An efficient route to highly substituted indoles was developed. It includes regioselective functionalization of tetrahydroindol-4(5H)-ones, prepared by ring-opening cyclization of cyclohexane-1,3-dione-2-spirocyclopropanes with primary amines, and subsequent oxidation. 6-Substituted indoles were synthesized from a readily available 5-substituted cyclohexane-1,3-dione-2-spirocyclopropane. Synthesis of 5- and 7-substituted indoles was achieved by regioselective electrophilic alkylation of tetrahydroindol-4(5H)-one, followed by oxidation. 4-Substituted indoles were synthesized by nucleophilic alkylation of the corresponding pyrrole derivative, prepared by partial oxidation of tetrahydroindol-4(5H)-one, and a sequential oxidation. Synthesis of 4-substituted indoles was also accomplished by Pd-catalyzed coupling of 4-hydroxyindole-derived triflates. Furthermore, synthesis of 4,5,6,7-tetrasubstituted indoles was achieved by using these regioselective alkylations
