Frontier of Opportunity: The Social Organization of Self-Employment in Winnipeg, Manitoba, 1881-1901
In the 1870s and early 1880s Winnipeg seemed a frontier of opportunity for hundreds
of men seeking a future in business. This article links the manuscript census
records and the credit reports of Dun, Wiman and Co. for 1881, 1891, and 1901
to evaluate the prospects of self-employed businessmen. The rate of self-employment
in Winnipeg was higher in 1881 than that documented in studies of Ontario. This
higher rate was not sustained past 1901, however, and was accompanied in the
1880s and 1890s by a high rate of business closures. By the beginning of the
twentieth century, businesses fell under the surveillance of metropolitan credit
reporters who informed lenders of their capital and credit worthiness. Credit ratings
and business success became increasingly associated with capital, and those with
the least capital and without credit reports had the greatest difficulty in staying in
business.Dans les années 1870 et au début des années 1880, Winnipeg ressemblait à une
terre dâavenir pour des centaines dâhommes cherchant Ă se faire une vie dans le
monde des affaires. Cet article couple les documents manuscrits de recensement aux
rapports de solvabilité de Dun, Wiman and Co. pour les années 1881, 1891 et 1901
afin dâĂ©valuer les perspectives qui sâoffraient aux entrepreneurs autonomes. En
1881, le taux de travail indépendant observé à Winnipeg était plus élevé que celui
relevĂ© dans les Ă©tudes portant sur lâOntario. Ce taux supĂ©rieur ne sâest toutefois
pas maintenu aprĂšs 1901 et sâaccompagnait dans les annĂ©es 1880 et 1890 dâun taux
Ă©levĂ© de fermetures dâentreprises. Au dĂ©but du XXe siĂšcle, les entreprises tombĂšrent
sous la surveillance des agences mĂ©tropolitaines dâĂ©valuation du crĂ©dit, qui informaient
les prĂȘteurs de la suffisance de leur capital et de leur solvabilitĂ©. Les cotes
de solvabilité et le succÚs des entreprises devinrent de plus en plus associés au
capital et les entreprises ayant le moins de capital et nâayant pas de rapports de
solvabilité étaient celles qui avaient le plus de difficulté à rester en affaires

A Detailed Study of Giants and Horizontal Branch Stars in M68: Atmospheric Parameters and Chemical Abundances
In this paper, we present a detailed high-resolution spectroscopic study of
post main sequence stars in the Globular Cluster M68. Our sample, which covers
a range of 4000 K in , and 3.5 dex in , is comprised of
members from the red giant, red horizontal, and blue horizontal branch, making
this the first high-resolution globular cluster study covering such a large
evolutionary and parameter space. Initially, atmospheric parameters were
determined using photometric as well as spectroscopic methods, both of which
resulted in unphysical and unexpected , , , and
[Fe/H] combinations. We therefore developed a hybrid approach that addresses
most of these problems, and yields atmospheric parameters that agree well with
other measurements in the literature. Furthermore, our derived stellar
metallicities are consistent across all evolutionary stages, with
[Fe/H] = 2.42 ( = 0.14) from 25 stars. Chemical
abundances obtained using our methodology also agree with previous studies and
bear all the hallmarks of globular clusters, such as a Na-O anti-correlation,
constant Ca abundances, and mild -process enrichment.Comment: Accepted to the Astronomical Journa
First results from the UBC etch-alignment mosaic CCD
First imaging results are obtained with a new CCD mosaic prototype (3K x 3k,
15 \mu m pixels). The CCDs are aligned using an etched socket alignment
technique. Three different measurements of the alignment are made using star
images, test p attern images, and microscope analysis. The CCDs have an angular
misalignement o f less than 30 ppm. The composite device is flat to within \pm
3 \mu m, with rows/columns oriented to within 20 ppm. The use of an existing
technology with built in precision reduces many of the difficulties and
expenses typically encountered with mosaic detector construction. A new camera
being built for the UBC liquid mirror telescope is al so described.Comment: 11 pages, 6 figs, 3 tables To appear in SPIE Photonics West97 -
