The Seventh Census of Population in Canada, 1931

The results of the seventh census of population in Canada, taken as of June 1, 1931, are comprised in 14 octavo volumes, of which all except the final volume of maps and graphs and certain monographs to be included in the two volumes of census monographs, have been issued. The present review is confined to the population census proper, including, however, the topics of gainful occupations, earnings, and unemployment; on the other hand, agriculture, merchandising and services, and institutions are omitted. In other words, the present review is limited to volumes I-VII, together with those monographs included in volumes XII and XIII which treat the topics of these seven volumes, so far as the monographs themselves have been issued. The advantage of considering the monographs in connection with the corresponding topics of the census itself is obvious, since the detailed analytical treatment of the former helps to throw into clear light the census findings and adds materially to the value of the results. An outline of the contents of the several volumes may help to give perspective to the whole subject. Volume I contains, in addition to the administrative summary of the work of the census, a brief analysis and comment on each of the major subjects covered by the census, together with a selection of tables on all topics; the text covering 344 pages and the tables 1,177 pages. Volumes II-VII are devoted to tabular matter; volume II to population figures for local subdivisions, with details by sex, age, etc., for these areas; volume III to age classifications; volume IV to "cross classifications,” e.g. birthplace with racial origin, literacy, religion, etc.; volume V to wage-earners, earnings, families, and housing; volume VI to unemployment; and volume VII to occupation and industr

Color-banding California gulls at Great Salt Lake, Utah

journal articleIn 1938, under the Pacific Color-Banding Project initiated by the Western Bird-Banding Association to study gull migration and life history, We stern Gulls and Glaucous-winged Gulls were banded along the coast and California Gulls at Mono Lake, California. The following year banding was undertaken in the California Gull colony on Egg Island, Great Salt Lake, by the write rs and in 1940 at Rock Island in Utah Lake by Vasco M. Tanner and others. Banding continued on Egg Island from 1939 to 1942 inclusive and on Rock Island from 1940 to 1942. War time exigencies prevented banding in 1943. In 1944, however, operations were transferred to a newly established colony at Farming to in Bay which is much more accessible than Egg Island

Prediction Of The Nerve Conduction Abnormalities Frequently Associated With Carpal Tunnel Syndrome From Clinical Features

This study was undertaken to develop a clinically useful model for predicting electrophysiological abnormality in the nerve conduction tests used in the diagnosis of carpal tunnel syndrome (CTS). The prediction model combined commonly recorded clinical history, signs, and symptoms in a multivariate analysis. Electrophysiological abnormality and adjustments for the influencing variables (sex, distance, and temperature) were based on normative nerve conduction values obtained in a control group (n = 104). This was the first study in this topic area in which prediction bands were used to adjust the criteria for assigning abnormality to account for influencing variables. The variables used to represent nerve conduction abnormality were selected based on the literature, clinical usage, and investigation of their interrelationships.;Two hundred and eighty-five subjects with signs and symptoms of CTS who were referred for nerve conduction testing were evaluated by interview and physical examination by an investigator who was blind to the electrodiagnosis. Electrodiagnosis was performed without knowledge of the clinical information. The univariate relationships of the clinical variables with nerve conduction abnormality were examined by Chi square analyses to determine the variables to be included in the model.;The model most highly predictive of nerve conduction abnormality included the variables Flick sign, nocturnal discomfort, and family history (P = 0.910). Two other specifications of abnormality, based on the numbers of abnormal variables, were used to test the robustness of the prediction model with similar results, but symptom duration was also included in the model. Tests such as Tinel\u27s sign and Phalen\u27s test which are often recommended in diagnosing CTS were less useful in this study in the prediction of abnormality than information obtained from the history. It was noted that prediction based upon the inclusion of a number of variables in a multivariate analysis, was better than prediction based upon any single variable. This study strongly suggests that the probability of nerve conduction abnormality can be predicted from clinical signs and symptoms and thus could be particularly useful to clinicians who lack easy access to nerve conduction testing

Annotated check-list of the birds of Utah

journal articleThe following check-list is a by-product o f studies made by the writers since 1926 in gathering material for a work on The Birds of Utah which is now completed. The list includes four hundred three kinds of birds (species and subspecies) which are admitted to the actual state list and thirty-three kinds placed under hypothetical status representing introductions of doubtful success, probables, questionables and misidentifications. The total list of all kinds includes four hundred thirty-six names

Modeling and measurement of fault-tolerant multiprocessors

The workload effects on computer performance are addressed first for a highly reliable unibus multiprocessor used in real-time control. As an approach to studing these effects, a modified Stochastic Petri Net (SPN) is used to describe the synchronous operation of the multiprocessor system. From this model the vital components affecting performance can be determined. However, because of the complexity in solving the modified SPN, a simpler model, i.e., a closed priority queuing network, is constructed that represents the same critical aspects. The use of this model for a specific application requires the partitioning of the workload into job classes. It is shown that the steady state solution of the queuing model directly produces useful results. The use of this model in evaluating an existing system, the Fault Tolerant Multiprocessor (FTMP) at the NASA AIRLAB, is outlined with some experimental results. Also addressed is the technique of measuring fault latency, an important microscopic system parameter. Most related works have assumed no or a negligible fault latency and then performed approximate analyses. To eliminate this deficiency, a new methodology for indirectly measuring fault latency is presented

Shape computations without compositions

Parametric CAD supports design explorations through generative methods which compose and transform geometric elements. This paper argues that elementary shape computations do not always correspond to valid compositional shape structures. In many design cases generative rules correspond to compositional structures, but for relatively simple shapes and rules it is not always possible to assign a corresponding compositional structure of parts which account for all operations of the computation. This problem is brought into strong relief when design processes generate multiple compositions according to purpose, such as product structure, assembly, manufacture, etc. Is it possible to specify shape computations which generate just these compositions of parts or are there additional emergent shapes and features? In parallel, combining two compositions would require the associated combined computations to yield a valid composition. Simple examples are presented which throw light on the issues in integrating different product descriptions (i.e. compositions) within parametric CAD

How the asymmetry of internal potential influences the shape of I-V characteristic of nanochannels

Ion transport in biological and synthetic nanochannels is characterized by such phenomena as ion current fluctuations, rectification, and pumping. Recently, it has been shown that the nanofabricated synthetic pores could be considered as analogous to biological channels with respect to their transport characteristics \cite{Apel, Siwy}. The ion current rectification is analyzed. Ion transport through cylindrical nanopores is described by the Smoluchowski equation. The model is considering the symmetric nanopore with asymmetric charge distribution. In this model, the current rectification in asymmetrically charged nanochannels shows a diode-like shape of $I-V$ characteristic. It is shown that this feature may be induced by the coupling between the degree of asymmetry and the depth of internal electric potential well. The role of concentration gradient is discussed

Birds of the Navajo Country

journal articleThe Navajo country as covered in this paper lies in southeastern Utah and northeastern Arizona and is bounded on the north, west and south by the San Juan, Colorado, Little Colorado and Rio Puerco rivers and on the east by the Arizona-New Mexico state line. That part of the Navajo country lying in northwestern New Mexico, while not covered in this paper, is ecologically similar and is probably but little different faunistically
