    This study examines the issues associated with the systematic allocation of instructional personnel resources to tasks within education systems and develops a conceptual framework to organize knowledge and direct research in this area of enquiry. An evaluation of the current status of the field of enquiry concludes that existing mechanisms for the matching of teacher to task on a system-wide basis are manifestly inefficient, educationalists have paid scant attention to the problem and there is no recognizable body of knowledge relating to it. The basic elements of a rational system, the reward structure, selection criteria, and selection procedures are examined and a rational system, based on a consideration of the issues raised in that examination, is outlined. An approach to the analysis and comparison of systems is discussed and some suggestions on the modification of staffing arrangements to bring them more into accord with the 'realities' of the situation are made

    Efficiency and Competition in Canadian Banking

    Get PDF
    Allen and Engert report on recent research at the Bank of Canada on various aspects of efficiency in the Canadian banking industry. This research suggests that, overall, Canadian banks appear to be relatively efficient producers of financial services and they do not exercise monopoly or collusive-oligopoly power. The authors note the value of continuing to investigate opportunities to improve efficiency and competition in financial services in Canada.

    Are Canadian Banks Efficient? A Canada--U.S. Comparison

    Get PDF
    The authors compare the efficiency of Canada's largest banks with U.S. commercial banks over the past 20 years. Efficiency is measured in three ways. First, the authors study key performance ratios, and find that Canadian banks are as productive as U.S. banks. Second, they investigate whether there are economies of scale in the production functions of Canadian banks and broadly comparable U.S. bank-holding companies (BHCs). They find larger economies of scale for Canadian banks than for the U.S. BHCs, which suggests that Canadian banks are less efficient in terms of scale, and have more to gain in terms of efficiency benefits from becoming larger. Third, the authors measure cost-inefficiency in Canadian banks and in U.S. BHCs relative to the domestic efficient frontier in each country (the domestic best-practice institution). They find that Canadian banks are closer to the domestic efficient frontier than are the U.S. BHCs. Canadian banks have also moved closer to the domestic efficient frontier than have the U.S. BHCs over time. Finally, the authors examine the dispersion in cost-inefficiency found in Canadian banks and attribute some of the dispersion to differences in information and communication technology investment. Comparisons are made with the U.S. BHC experience.Financial institutions

    Energy Loss in Commercial Condensers

    Get PDF
    The investigation of the energy loss in condensers is one which electricians and experimenters have long carried on. Their efforts have been restricted chiefly to alternating currents. Many methods have been proposed and used with varying success. The losses in condensers are due to dielectric hysteresis and leakage. That the dielectric of a condenser becomes heated when an alternating current is applied to terminals has long been known. A condenser which has been charged does not lose its entire charge when it is discharged, part of it remaining as a residual charge. Kleiner used the thermo-couple embedded in the dielectric to determine the heating effect. His observation showed considerable heating effect in ebonite, gutta-percha, glass and mica, but none in rosin and paraffin

    A descriptive and evaluative bibliography of mathematics filmstrips.

    Submitted by A.W. Clark and R.W. Allen for the degree of Master of Arts and by C.H. Gardner and R.F. Sweeney for the degree of Master of Education. Thesis (Ed.M.)--Boston UniversityThe purpose of this paper is to present in one volume (1) a bibliography of all mathematics filmstrips from those suitable for the first grade to those suitable for use in senior high school and college, (2) an accurate description of each filmstrip, and (3) unbiased evaluations of each filmstrip by qualified teachers invited to take part in the project. Concomitant problems. The foregoing three parts were the heart of the problem and the portion nearly completely solved. There were, however, concomitant problems which have been partially solved by this work. The first of these concerns the limited use of filmstrips by mathematics teachers. Undoubtedly many do not believe in using filmstrips in mathematics classes. Others have never given serious thought about the advisability of using filmstrips. In later sections of this chapter and throughout this work evidence is cited to support the contention that filmstrips should have serious consideration, and that they are useful in mathematics classes. The second concomitant problem concerns the revision of current filmstrips and production of new ones. The filmstrip producers were supplied, upon their request, with summaries of the evaluations. Summaries were supplied only at the producer's request; for unless they were interested enough to request the summaries, they probably would not be interested in changing or improving their filmstrips. Summary. The problem, then, had three major parts: listing , describing, and evaluating mathematics filmstrips, and two concomitant parts: arousing the mathematics teacher's interest in filmstrips, and encouraging producers to make better productions and necessary revisions in current productions.

    Structure and thermodynamics of a mixture of patchy and spherical colloids: a multi-body association theory with complete reference fluid information

    Get PDF
    A mixture of solvent particles with short-range, directional interactions and solute particles with short-range, isotropic interactions that can bond multiple times is of fundamental interest in understanding liquids and colloidal mixtures. Because of multi-body correlations predicting the structure and thermodynamics of such systems remains a challenge. Earlier Marshall and Chapman developed a theory wherein association effects due to interactions multiply the partition function for clustering of particles in a reference hard-sphere system. The multi-body effects are incorporated in the clustering process, which in their work was obtained in the absence of the bulk medium. The bulk solvent effects were then modeled approximately within a second order perturbation approach. However, their approach is inadequate at high densities and for large association strengths. Based on the idea that the clustering of solvent in a defined coordination volume around the solute is related to occupancy statistics in that defined coordination volume, we develop an approach to incorporate the complete information about hard-sphere clustering in a bulk solvent at the density of interest. The occupancy probabilities are obtained from enhanced sampling simulations but we also develop a concise parametric form to model these probabilities using the quasichemical theory of solutions. We show that incorporating the complete reference information results in an approach that can predict the bonding state and thermodynamics of the colloidal solute for a wide range of system conditions.Comment: arXiv admin note: text overlap with arXiv:1601.0438

    Dynamics in a supercooled liquid of symmetric dumbbells: Reorientational hopping for small molecular elongations

    Full text link
    We present extensive molecular dynamics simulations of a liquid of symmetric dumbbells, for constant packing fraction, as a function of temperature and molecular elongation. For large elongations, translational and rotational degrees of freedom freeze at the same temperature. For small elongations only the even rotational degrees of freedom remain coupled to translational motions and arrest at a finite common temperature. The odd rotational degrees of freedom remain ergodic at all investigated temperature and the temperature dependence of the corresponding characteristic time is well described by an Arrhenius law. Finally, we discuss the evidence in favor of the presence of a type-A transition temperature for the odd rotational degrees of freedom, distinct from the type-B transition associated with the arrest of the translational and even rotational ones, as predicted by the mode-coupling theory for the glass transition.Comment: 4 pages, 3 figure
