Comparative Examination

Popular perceptions of “boom” and “bust” communities, supported by some of the earlier literature and anecdotal descriptions of life in such circumstances, have suggested that the quality of life in these conditions is seriously jeopardized. On the basis of an examination of one “boom” and two “bust” communities in Northern Ontario along with several comparison communities, and an examination of the available literature, some of the earlier claims of large scale social casualty rates are questioned. Both “boom” and “bust” communities appear to experience predictable phases of development. It is suggested that the principal human service needs vary from stage to stage in both. A number of implications for program planners are identified. It is suggested that future research would most profitably be devoted to longitudinal studies of communities entering either a “boom” or “bust” phase.

<p>Changes in the far north of Ontario (&gt;50°N latitude), like climate warming and increased industrial development, will have direct effects on watershed characteristics and lakes. To better understand the nature of remote northern lakes that span the Canadian Shield and Hudson Bay Lowlands, and to address the pressing need for limnological data for this vast, little-studied area of Ontario, lake chemistry surveys were conducted during 2011-2012. Lakes at the transition between these physiographic regions displayed highly variable water chemistry, reflecting the peatland landscape with a mix of bog and fen watersheds, and variations in the extent of permafrost. In the transition area, Shield and Lowlands lakes could not be clearly differentiated based on water chemistry; peat cover decouples, to varying degrees, the lakes from the influences of bedrock and surficial deposits. Regional chemistry differences were apparent across a much broader area of northern Ontario, due to large-scale spatial changes in geology and in the extent of peatlands and permafrost.  Shield lakes in the far northwest of Ontario had Ca, Mg, and TP concentrations markedly higher than those of many Lowlands lakes and previously studied Shield lakes south of 50°N, related to an abundance of lacustrine and glacial end-moraine deposits in the north.</p>

Cruise Lines

Winter browsing patterns by moose (Alces alces) were studied on three cutovers in northern Ontario during spring and summer of 1975 and 1976. The three cutovers were 5 to 6 years old and ranged from 24 to 525 ha in area. Browse patterns were determined by examining 2 m × 4 m plots spaced at 25 m intervals along selected cruise lines. The distance from cover for each plot was calculated from large scale maps. No correlation was found between distance from cover and browse abundance, and moose browsing was independent of food distribution. In 1975, it was found that 95% of all browsing activity was confined to within 80 m of cover. Browse use tended to be greater in 1976, with significant use extending as far as 260 m from cover in one cutover. Food abundance and snow depths up to 75 cm apparently did not determine moose distribution.

The Great War

AbstractSeptember 1931 is seen by historians as one of the key months in interwar British history. It was the first full month of the National Government, the month of the Invergordon Mutiny and of Britain being forced off the gold standard. It was also the month when large-scale celebrations were held to mark the centenary of the discovery of electromagnetic induction by Michael Faraday. This address discusses the specific events of celebrating Faraday and its consequences; it is framed in relation to, and in some instances directly linked with, the crises of that month and some of the consequences of the Great War, especially the growth of the corporate and coordinated state and the rise of modernity.Let us honour if we canThe Vertical manThough we value noneBut the horizontal one.W. H.

Abstract Vibrational energy harvesting has attracted considerable research attention for electrical power collection from ambient vibrations. Thereby, this study firstly developed an electromagnetic energy harvester of large-scale bistable motion by application of stochastic resonance, to enhance energy harvesting efficiency at a broadly low frequency. The electromagnetic energy harvester is fabricated by a magnet-coil generator and an oblique-supported spring-mass system. In the beginning, a weighting function is originally proposed considering mutual position relationship of the magnet and coil, and a motion equation and an electromagnetic induction equation are simultaneously established considering both elastic spring recovery force and electromagnetic induction Lorentz force. Subsequently, numerical analysis is processed to resolve the simultaneous equations to obtain systematic response displacement and the induced voltage, and the numerical solutions are accurately consistent with the measuring results in validation experiments. Furthermore, a damping coefficient is identified considering the mutual effectiveness of the damping forces from the normal friction and electromagnetic induction, and the influence of electromagnetic induction damping on systematic response displacement is carefully discussed. Eventually, experimental results clarified that the stochastic resonance phenomenon actually occurred as a large-scale bistable motion, and it is further validated that power generation efficiency can be noticeably enhanced following amplitude amplifications of systematic response displacement.
