    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

    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

    Get PDF
    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

    Get PDF
    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

    A Specification of the Soar Cognitive Architecture in Z

    Get PDF
    A formal specification of the sixth revision of the Soar architecture in the Z notation was constructed to elucidate and clarify the definition of Soar and to guide its implementation. Soar is a cognitive architecture that has been successfully applied to many domains and has been proposed as an exemplar unified theory of cognition. Z is a model theoretic specification language based in set theory that has syntax and type checking programs available. The specification has a complete coverage of the architecture, a low level of abstraction and a considerable implementation bias

    “Catch 22”: biosecurity awareness, interpretation and practice amongst poultry catchers

    Get PDF
    Campylobacter contamination of chicken on sale in the UK remains at high levels and has a substantial public health impact. This has prompted the application of many interventions in the supply chain, including enhanced biosecurity measures on-farm. Catching and thinning are acknowledged as threats to the maintenance of good biosecurity, yet the people employed to undertake this critical work (i.e. ‘catchers’) are a rarely studied group. This study uses a mixed methods approach to investigate catchers’ (n = 53) understanding of the biosecurity threats posed by the catching and thinning, and the barriers to good biosecurity practice. It interrogated the role of training in both the awareness and practice of good biosecurity. Awareness of lapses in biosecurity was assessed using a Watch-&-Click hazard awareness survey (n = 53). Qualitative interviews (n = 49 catchers, 5 farm managers) explored the understanding, experience and practice of catching and biosecurity. All of the catchers who took part in the Watch-&-Click study identified at least one of the biosecurity threats with 40% detecting all of the hazards. Those who had undergone training were significantly more likely to identify specific biosecurity threats and have a higher awareness score overall (48% compared to 9%, p = 0.03). Crucially, the individual and group interviews revealed the tensions between the high levels of biosecurity awareness evident from the survey and the reality of the routine practice of catching and thinning. Time pressures and a lack of equipment rather than a lack of knowledge appear a more fundamental cause of catcher-related biosecurity lapses. Our results reveal that catchers find themselves in a ‘catch-22â€Č situation in which mutually conflicting circumstances prevent simultaneous completion of their job and compliance with biosecurity standards

    In this article we take a step towards providing an analysis of the Soar architecture as a basis for general intelligence. Included are discussions of the basic assumptions underlying the development of Soar, a description of Soar cast in terms of the theoretical idea of multiple levels of description, an example of Soar performing multi-column subtraction, and three analyses of Soar: its natural tasks, the sources of its power, and its scope and limitsPeer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29595/1/0000684.pd
