Regulation and testing of wattmeters
Citation: Fielding Jr., George T. Regulation and testing of wattmeters. Senior thesis, Kansas State Agricultural College, 1903.Morse Department of Special CollectionsIntroduction: The business of electric lighting and power distribution from central stations has grown to such a volume that millions of dollars change hands yearly in the transaction of that business. The commodity exchanged is the electric current and yet there is great uncertainty as to what that so called current really is. Considering this fact, the enormity of the business built upon this invisible something is rather surprising. The general lack of definite knowledge on the subject and the fact that the commodity is intangible are perhaps responsible for the laxity that has existed in the buying and selling of electrical power until a comparatively recent time. The sale of current involving large sums is often based upon measurements taken with poor, inefficient instruments or upon a system of calculation closely allied with guessing. Such .a manner of doing business would have resulted in bankruptcy in any other line, but the spirit of the age has entered the trade and the cry for the past few years has been for a more accurate system and this means better instruments. While the station manager knows that his financial success depends largely upon the excellence and efficiency of his plant yet he cannot shut his eyes to the fact that his income depends largely upon the system by which he sells his current. Dissatisfied Or suspicious customers are not conducive to prosperous trade, and dissatisfied they will be if they feel that there is inaccuracy or guessing in their accounts. The effect of poor measuring devices usually reacts in two ways upon the central station manager for beside trouble with customers he also has to stand a loss from inefficient metering, this loss often amounting to eight per cent of the current going through the meters. With the rapid strides of electrical enterprise, however, the improvement and manufacture of electric meters has in a large measure kept pace and today there are on the market a number of very efficient meters
Aging in a mean field elastoplastic model of amorphous solids
We construct a mean-field elastoplastic description of the dynamics of amorphous solids under arbitrary time-dependent perturbations, building on the work of Lin and Wyart [Phys. Rev. X 6, 011005 (2016)] for steady shear. Local stresses are driven by power-law distributed mechanical noise from yield events throughout the material, in contrast to the well-studied Hébraud–Lequeux model where the noise is Gaussian. We first use a mapping to a mean first passage time problem to study the phase diagram in the absence of shear, which shows a transition between an arrested and a fluid state. We then introduce a boundary layer scaling technique for low yield rate regimes, which we first apply to study the scaling of the steady state yield rate on approaching the arrest transition. These scalings are further developed to study the aging behavior in the glassy regime for different values of the exponent μ characterizing the mechanical noise spectrum. We find that the yield rate decays as a power-law for 1 < μ < 2, a stretched exponential for μ = 1, and an exponential for μ < 1, reflecting the relative importance of far-field and near-field events as the range of the stress propagator is varied. A comparison of the mean-field predictions with aging simulations of a lattice elastoplastic model shows excellent quantitative agreement, up to a simple rescaling of time

The Morality of Moral Education
The Background - Moral Education as the Traditional Source of Personal Development. One of the abiding interests of moral philosophy is how some measure of competence at existence can not only be attained, but attained to an excellent degree. The idea that man is born imperfect but may so order his life that he approaches a more complete state of perfection has been echoed in the words and deeds of men through the ages. It is reflected in our willingness to revere those men and women who in their lives neared the condition of existential entelechy. Throughout the ages, for instance, humankind has sought out heroes and martyrs who by virtue of their superior conduct and more impressive virtues have become the models upon which lesser men and women model their own lives

A Study of the Physical Facilities Needed for Organizing, Administrating, and Implementing Vocational-Industrial Education in the Monahans-Wickett-Pyote Independent School District
The purpose of the study was to gather information that would be helpful in planning and implementing a vocational education program in the Monahans-Wickett-Pyote Independent School District in response to a written request by George L. Cullender, Superintendent of Schools. This study was intended to supplement the Texas Education Agency's occupational survey
Chinese immigrant parents' vaccination decision making for children: A qualitative analysis
Background: While immunization coverage rates for childhood routine vaccines in Hong Kong are almost 100%, the uptake rates of optional vaccines remain suboptimal. Understanding parental decision-making for children's vaccination is important, particularly among minority groups who are most vulnerable and underserved. This study explored how a subsample of new immigrant mothers from mainland China, a rapidly-growing subpopulation in Hong Kong, made decisions on various childhood and adolescent vaccines for their offspring, and identified key influences affecting their decision making. Methods. Semi-structured in-depth interviews were conducted with 23 Chinese new immigrant mothers recruited by purposive sampling. All interviews were audio-taped, transcribed and analyzed using a Grounded Theory approach. Results: Participants' conversation revealed five underlying themes which influenced parents' vaccination decision-making: (1) Institutional factors, (2) Insufficient vaccination knowledge and advice, (3) Affective impacts on motivation, (4) Vaccination barriers, and (5) Social influences. The role of social norms appeared overwhelmingly salient influencing parents' vaccination decision making. Institutional factors shaped parent's perceptions of vaccination necessity. Fear of vaccine-targeted diseases was a key motivating factor for parents adopting vaccination. Insufficient knowledge about vaccines and targeted diseases, lack of advice from health professionals and, if provided, suspicions regarding the motivations for such advice were common issues. Vaccination cost was a major barrier for many new immigrant parents. Conclusions: Social norms play a key role influencing parental vaccination decision-making. Insight gained from this study will help inform healthcare providers in vaccination communication and policymakers in future vaccination programme. © 2014 Wang et al.; licensee BioMed Central Ltd.Link_to_subscribed_fulltex
