A Comparative Study Of The Coach\u27s Load In The Tristate Area With That Of The Teacher\u27s As Prescribed By The Texas Department Of Education
Origin and Purpose of Problem
Hundreds of freshmen are entering Prairie View Agricultural and Mechanical College each year, a number of them have a very poor background in physical education. Since many studies have already been made dealing directly with the freshmen, I have turned my attention to the high school teachers, using the coaches and Physical Education teachers in the Trl-State Area ( Oklahoma, Texas, and New Mexico) as representative examples to see if they may be in any way responsible for the difficulties of the students. The necessity of well-qualified coaches has become increasingly important. Recent wars have demanded the services of the majority of the United States\u27 most physically fit young men. The low percentage of physically fit young men has certainly given rise to special emphasis in the teaching of physical education in the public schools of America. Sports and athletics play a major role in the development of the youth of today Young people have learned to relax and to develop strong, healthy bodies through physical education courses.
In order that the students get a well-rounded knowledge of the fundamentals in physical education, it is important that they receive the best training possible In high school, It Is the belief of this writer that part of the fault of the students\u27 failure in physical education and lack of skills in a variety of activities may be due to the type of instruction they receive In high school. Many ideas may be advanced as to the reasons why inadequate instruction might have been given. The writer believes that the load of the coach and physical education teacher is probably the one thing that has affected the type of Instruction the high school graduates received most, It is for this reason a study was undertaken to see just how the load of the coaches* in this area compared with that of the regular classroom teachers

Toward a Unified Theory of Immediate Reasoning in Soar
Soar is an architecture for general intelligence that has been proposed as a unified theory of human cognition (UTC) (Newell, 1989) and has been shown to be capable of supporting a wide range of intelligent behavior (Laird, Newell & Rosenbloom, 1987; Steier et al, 1987). Polk & Newell (1988) showed that a Soar theory could account for human data in syllogistic reasoning. In this paper, we begin to generalize this theory into a unified theory of immediate reasoning based on Soar and some assumptions about subjects' representation and knowledge. The theory, embodied in a Soar system (IR-Soar), posits three basic problem spaces (comprehend, test-proposition, and build-proposition) that construct annotated models and extract knowledge from them, learn (via chunking) from experience and use an attention mechanism to guide search. Acquiring task specific knowledge is modeled with the comprehend space, thus reducing the degrees of freedom available to fit data. The theory explains the qualitative phenomena in four immediate reasoning tasks and accounts for an individual's responses in syllogistic reasoning. It represents a first step toward a unified theory of immediate reasoning and moves Soar another step closer to being a unified theory of all of cognition

Towards an Interaction-Centered and Dynamically Constructed Episodic Memory for Social Robots
Hassan T, Kopp S. Towards an Interaction-Centered and Dynamically Constructed Episodic Memory for Social Robots. In: Companion of the 2020 ACM/IEEE International Conference on Human-Robot Interaction (HRI ’20 Companion). New York: ACM; 2020.This paper outlines an interaction-centered and dynamically constructed episodic memory for social robots, in order to enable naturalistic, social human-robot interaction. The proposed model includes a record of multi-timescale events stored in the event history, a record of multi-timescale interval definitions stored as interaction episodes, and a set of links associating specific elements of the two records. The event history is constructed dynamically, depending on the occurrence of internal and external events. The interaction episodes are defined on the basis of robot-initiated and
user-initiated interactions. The episodic memory is realised within a social human-robot interaction architecture, whose components
generate events pertaining to the context and state of interaction
UBV stellar photometry of bright stars in GC M5. I. UV colour-magnitude and colour-colour diagrams and some peculiarities in the HB stellar distribution
We present stellar photometry in the UBV passbands for the globular cluster
M5 = NGC5904. The observations, short-exposured photographic plates and CCD
frames, were obtained in the RC-focus of the 2m telescope of the Natl. Astron.
Obs. 'Rozhen'. All stars in an annulus with radius 1 < r < 5.5 arcmin were
measured. We show that the UV CMDs describe different evolutionary stages in a
better manner than the 'classical' (V, B-V) diagram. We use HB stars, with
known spectroscopic Teff, to check the validity of the colour zero-point. A
review of all known UV-bright star candidates in M5 is made and some of their
parameters are catalogued. Six new stars of this kind are suspected on the
basis of their position on the CMD. New assessment of the cluster reddening and
metallicity is done using the (U-B, B-V) diagram. We find [Fe/H]= -1.38, which
confirms the Zinn & West (1984) value contrasting with recent spectroscopic
estimates. In an effort to clarify the question of the gap in the BHB stellar
distribution and to investigate some other peculiarities, we use the relatively
long-base colour index U-V. A comparison of the unreddened (V, U-V)
distribution of HB stars with a canonical ZAHB model (Dorman et al. 1993)
reveals that the hottest stars rise above the model line. We find this similar
to the 'u-jump' found in the Stroemgren photometry (Grundahl et al. 1998,
1999). (U-B)o indeces of 18 BHB stars with (B-V)o in [-0.02, 0.18] were used to
estimate their ultraviolet deficiency. It is shown that low gravity log g < 2
Kurucz's atmospheric models fit well the observed distribution of these stars
along the two-colour diagram.Comment: 9 pages, 7 EPS figures. MNRAS accepte

Effects of solar wind magnetosphere coupling recorded at different geomagnetic latitudes: Separation of directly-driven and storage/release systems
The effect on geomagnetic activity of solar wind speed, compared with that of the strength of the interplanetary magnetic field, differs with geomagnetic latitude. In this study we construct a new index based on monthly standard deviations in the H-component of the geomagnetic field for all geomagnetic latitudes. We demonstrate that for this index the response at auroral regions correlates best with interplanetary coupling functions which include the solar wind speed while mid- and low-latitude regions respond to variations in the interplanetary magnetic field strength. These results are used to isolate the responsible geomagnetic current systems
Cusp energetic particle events: Implications for a major acceleration region of the magnetosphere
The Charge and Mass Magnetospheric Ion Composition Experiment (CAMMICE) on board the Polar spacecraft observed 75 energetic particle events in 1996 while the satellite was at apogee. All of these events were associated with a decrease in the magnitude of the local magnetic field measured by the Magnetic Field Experiment (MFE) on Polar. These new events showed several unusual features: (1) They were detected in the dayside polar cusp near the apogee of Polar with about 79% of the total events in the afternoonside and 21% in the morningside; (2) an individual event could last for hours; (3) the measured helium ion had energies up to and many times in excess of 2.4 MeV; (4) the intensity of 1–200 KeV/e helium was anticorrelated with the magnitude of the local geomagnetic field but correlated with the turbulent magnetic energy density; (5) the events were associated with an enhancement of the low-frequency magnetic noise, the spectrum of which typically extends from a few hertz to a few hundreds of hertz as measured by the Plasma Wave Instrument (PWI) on Polar; and (6) a seasonal variation was found for the occurrence rate of the events with a maximum in September. These characterized a new phenomenon which we are calling cusp energetic particle (CEP) events. The observed high charge state of helium and oxygen ions in the CEP events indicates a solar source for these particles. Furthermore, the measured 0.52–1.15 MeV helium flux was proportional to the difference between the maximum and the minimum magnetic field in the event. A possible explanation is that the energetic helium ions are energized from lower energy helium by a local acceleration mechanism associated with the high-altitude dayside cusp. These observations represent a potential discovery of a major acceleration region of the magnetosphere
Impact of rhizome quality on Miscanthus establishment in claypan soil landscapes
Thousands of eroded-soil hectares in the U.S. Midwest have been planted to Miscanthus Ă— giganteus as an industrial or bioenergy crop in recent years, but few studies on factors affecting crop establishment have been performed on these soils. The objective of this study was to quantify how both rhizome quality and depth of soil from the surface to the first argillic horizon (or depth to claypan (DTC1)) affected M. Ă— giganteus establishment. Rhizome quality (i.e., mass, length, diameter, viable buds, score), emergence, growth, and winter survival were measured on rhizomes planted in 2013 at Columbia and 2014 at Centralia, Missouri on clay loam soils with a range of DTC. Rhizome emergence and early tillering slightly increased as DTC increased, but these effects on growth diminished as the season progressed. Rhizome emergence and growth were more influenced by some metrics of rhizome quality; the odds of a rhizome emerging increased by 25 and 40% with each 1 cm and 1 bud increase in rhizome length and active bud count, respectively. Furthermore, late tiller counts, basal circumference, and end-of-season biomass increased as rhizome length and mass increased. Winter survival could not be estimated as well as emergence, but the odds of survival across sites increased by 5% with each 1 cm increase in rhizome length. When DTC was categorized as soil erosion class or landscape position, only the backslope at Centralia caused greater M. Ă— giganteus growth than other positions. These findings demonstrate the resiliency of M. Ă— giganteus for early growth and establishment on even the most degraded parts of the claypan soil landscape and indicate that propagating larger rhizomes will improve establishment
