    Structure and Trends of Rural Employment: Canada in the Context of OECD Countries

    Get PDF
    In 1991, 33 percent of Canada's population lived in predominantly rural regions. Employment growth in rural regions averaged 1.3 percent per year over the 1980s, ranking fourth among OECD countries. In 1991, only 11 percent of the rural workforce in Canada were working in agriculture, forestry or fishing. Within rural regions, employment growth was highest in rural areas adjacent to metropolitan centres. Business services was the fastest growing sector in all types of regions, but rural regions received only a minor boost due to the relatively low share of their workforce in business services. On average, rural areas showed less growth - however, within rural areas, there were regions that showed more growth than urban regions. Rurality does not necessarily imply slow employment growth.Community/Rural/Urban Development, Labor and Human Capital,

    Most software engineering graduates begin their careers lacking an appreciation of real-world conditions. Do universities have the resources to simulate this environment or must software companies provide such training themselves

    A New Approach to Non-CMA/CA Areas

    Non-metropolitan areas in Canada are often simply referred as rural Canada, without enough attention paid to their inner differences. The Metropolitan Influence Zones (MIZ) conceptual framework allows us to divide non-metropolitan areas into No Metropolitan Influence Zone (No MIZ), Weak Metropolitan Influence Zone (Weak MIZ), and Moderate Metropolitan Influence Zone (Moderate MIZ), according to the commuting flows to and from metropolitan areas. Analyses on New Brunswick show that the nonmetropolitan population are economically disadvantaged overall compared to metropolitan population. However, there are substantial differences within nonmetropolitan areas. Population in the No Metropolitan Influence Zone do not appear to be the most disadvantaged economically. In so far as the No Metropolitan Zone may be regarded as the most rural, this casts doubt on the conventional wisdom regarding "rural" as the synonym of socio-economic disadvantage. In fact, the urban population in the No Metropolitan Influence Zone is shown to be the most disadvantaged economically. The pattern in Saskatchewan is quite different from New Brunswick. In general, median family income decreases, unemployment rate and incidence of low income families increase as the influence of metropolitan areas decreases. Together with the findings concerning New Brunswick, it is clear that non-metropolitan Canada is anything but homogeneous. More research is needed to bring out this diversity so that social policies can be better tailored to the needs of non-metropolitan Canadian population.Community/Rural/Urban Development,

    Optimization-based Groundwater Modeling of Aqueous Phase Dnapl to Enhance Plume Remediation Management

    Water Resources Engineering. Research was performed for the small military installation of Vance AFB to evaluate and optimize the current remediation Long-Term Monitoring Plan. Two shallow aquifer groundwater plumes contaminated with the DNAPL chemical trichloroethylene (TCE) were analyzed with two public domain software programs, Monitoring and Remediation Optimization Software (MAROS) and Geostatistical Temporal/Spatial (GTS) Algorithm, adopted by the Air Force Center of Environmental Excellence. The goal to reduce wells and testing utilized Mann-Kendall, linear regression, Delaunay triangulation, Modified Cost Estimating System weighting, thinning, locally-weighted quadratic equations, temporal variogram, and a comparison with Parsons Three-Tiered approach. Findings: Irregular test data was reformatted from several sources using Excel. Other remediation construction such as cutoff walls and extraction wells complicated definition of representative plume boundaries. Evaluation of a small portion of dissolved TCE did not account for residual contamination. Recommendations to reduce testing frequency and the number of monitoring wells offered a minimum cost saving of 52,000 per year. GTS could not operate with minimum data set for Vance. 1. MAROS can operate with minimal data sets with less information than required by other Long Term Monitoring Optimization Software as shown by the operation of the GTS software. 2. The effect of limited well test data from contaminated plumes demonstrates that analysis is primarily dependent upon temporal data and frequency. It does not matter how many wells are present if the data is not first organized into periods of testing and set at specific calendar dates. 3. The most efficient form for updating and inputting data into MAROS is Excel format. ERPIMS is extremely difficult to access from a layman's level and excellent support if provided by the Air Force help desk that sponsors the software. 4. In comparison to the higher level GTS statistical optimization program, MAROS is rated the simplest software to operate. Input data is minimal for the general site, geography, stratigraphy, and hydrogeology. 5. The attained results of MAROS remediation do not necessarily correlate with attainment criteria of the regulators. For instance, the MAROS recommendation for deletion of wells differed significantly from the simpler ODEQ criteria of recording less than MCL levels for six straight testing periods.School of Civil & Environmental Engineerin

    Slipping friction of an optically and magnetically manipulated microsphere rolling at a glass-water interface

    Full text link
    The motion of submerged magnetic microspheres rolling at a glass-water interface has been studied using magnetic rotation and optical tweezers combined with bright-field microscopy particle tracking techniques. Individual microspheres of varying surface roughness were magnetically rotated both in and out of an optical trap to induce rolling, along either plain glass cover slides or glass cover slides functionalized with polyethylene glycol. It has been observed that the manipulated microspheres exhibited nonlinear dynamic rolling-while-slipping motion characterized by two motional regimes: At low rotational frequencies, the speed of microspheres free-rolling along the surface increased proportionately with magnetic rotation rate; however, a further increase in the rotation frequency beyond a certain threshold revealed a sharp transition to a motion in which the microspheres slipped with respect to the external magnetic field resulting in decreased rolling speeds. The effects of surface-microsphere interactions on the position of this threshold frequency are posed and investigated. Similar experiments with microspheres rolling while slipping in an optical trap showed congruent results.Comment: submitted to Journal of Applied Physics, 11 figure

    Clustering of Very Red Galaxies in the Las Campanas IR Survey

    Full text link
    We report results from the first 1000 square arc-minutes of the Las Campanas IR survey. We have imaged 1 square degree of high latitude sky in six distinct fields to a 5-sigma H-band depth of 20.5 (Vega). Optical imaging in the V,R,I,and z' bands allow us to select color subsets and photometric-redshift-defined shells. We show that the angular clustering of faint red galaxies (18 3) is an order of magnitude stronger than that of the complete H-selected field sample. We employ three approaches to estimate n(z)n(z) in order to invert w(theta) to derive r_0. We find that our n(z) is well described by a Gaussian with = 1.2, sigma(z) = 0.15. From this we derive a value for r_0 of 7 (+2,-1) co-moving H^{-1} Mpc at = 1.2. This is a factor of ~ 2 larger than the clustering length for Lyman break galaxies and is similar to the expectation for early type galaxies at this epoch.Comment: 5 pages, 2 figures, 1 table.

    Analysis of Dynamic Load Factor in a Fail-safe Crane Equipped with a Hydraulic Equalizing Cylinder

    Get PDF
    A model is proposed for the dynamic behavior of an equalizing cylinder when coupled to a fail-safe crane mechanism. The constitutive equations involve the continuity of the fluid in the equilizing bar and time-dependent incompressible one-dimensional Navier-Stokes equations for the detailed motion of the cylinder coupled with the dynamics of the traveling block and the elastic cable. These yields a nonlinear 2nd-order ordinary differential equations. The results for the Dynamic Load Factor (DLF) is presented
