Methodological reflections on media and counter hegemonic protest in India
This paper sets the issues and questions for interdisciplinary academic study of local protest with global claims,as it relates to use of the media. The author presents an historical background before then using the example of Arundhati Roy's writing on the Narmada Dams controversy and her essay 'walking with the comrades' on jungle Naxalite protest in India as a vehicle for analysis the uses of new Gramsci'ist counter hegemony theory, combined with elements of Judith Butler's ideas on performance and the media. What do these mean for activist articulations in the media
Lime Needs and Trends in Arkansas
Consumption of agricultural lime in Arkansas declined significantly during the past seven years. During each of the past four years, lime consumption was lower than any time since 1960. The quantity of lime needed for optimum crop production on Arkansas\u27 soils is estimated to be 2,678,700 metric tons (MT) (3,000,000 tons), based on University of Arkansas soil testing summaries. Since 1980, less than 285,728 MT(320,000 tons) of lime have been used each year. It is the natural tendency for most soils in Arkansas to become more acidic with time. Periodic addition of agricultural limestone, however, can neutralize soil acidity and help to maintain soil productivity. Nitrogen fertilizers, applied for the production of most agricultural crops, may also contribute to the acidification of soils. The annual consumption of acid-forming nitrogen fertilizers in Arkansas increased from approximately 223,225 MT(250,000 tons) during fiscal year 1974-75 to about 392,876 MT(440,000 tons) by fiscal year 1983-84. At least 2.5 times more lime was needed than was used, just to neutralize the residual acidity from acid-forming nitrogen fertilizers alone, during the same period. Shifts in crop hectareages did not account for the magnitude of decline observed in lime consumption. If lime consumption does not increase in the future, and if acid-forming nitrogen fertilizer consumption follows the current increasing trend, soil acidity will cause a decline in the yields of acid-sensitive crops
An exploration of executive coaching as an experiential learning process within the context of the integrated experiential coaching model.
This research project involved a phenomenological exploration of executive coaching as an experiential learning process within the context of the Integrated Experiential Coaching Model. This model proposes that executive coaching is about facilitating integrated experiential learning in individuals in order to facilitate personal growth and development with the aim of improving individual and organizational performance. It is not therapy. It is integrated in that it caters for Schumacher’s Four Fields of Knowledge and Wilber’s Integral Model which caters for personal development through various levels of consciousness, especially in the personal and transpersonal levels. It is experiential in that it uses Kolb’s Experiential Learning model as the injunction and uses Harri-Augstein and Thomas’s concept of Learning Conversations as the primary learning tool.
An adapted version of the Transcendental Phenomenological Methodology of Moustakas was chosen to explore and discover the meaning and essence of the learning experience while being coached within the context of the Integrated Experiential Coaching Model. It was hypothesised that the Integrated Experiential Coaching Model facilitated both the prehension and transformational dimensions of Experiential Learning in individuals. The co-researchers understood and owned some significant behavioural dynamics inside of themselves, as well as between themselves and other significant colleagues. This underlines the possibilities of coaching as a staff development intervention to facilitate self-authorisation by working through one’s own unconscious and dynamic behavioural issues. It was hypothesised that coaching presented from this model empowers individual employees to work towards their own cognitive insight, the experience of emotional meaningfulness and taking of responsibility for their own growth and career development
Four bugs on a rectangle
The problem of four bugs in cyclic pursuit starting from a 2-by-1 rectangle is considered, and asymptotic formulas are derived to describe the motion. In contrast to the famous case of four bugs on a square, here the trajectories quickly freeze to essentially one dimension. After the first rotation about the centre point, the scale of the configuration has shrunk by a factor of 10^427907250, and this number is then exponentiated four more times with each successive cycle. Relations to Knuth’s double-arrow notation and level-index arithmetic are discussed
Comet Halley returns: A teachers' guide 1985-1986
This booklet has been put together as an aid for teachers in elementary and secondary schools. It is divided into two distinct parts. The first part is a brief tutorial which introduces some of the most important concepts about comets, including their historical significance. A list of selected readings is provided at the end of the booklet. The second part of the booklet contains a number of suggested activities, built around the comet. These include both classroom exercises and carefully described field work to observe the comet. Guidance is provided on where to look for the comet, how to observe it, and to photograph it
Transformation of scientists and engineers into managers
The purposes of this research were to determine the principal problems and obstacles faced by specialists during the transition period when they are becoming managers, and to discover ways by which their difficulties might be avoided or overcome. It was found that senior management officials are unaware--or tend to ignore the importance--of the transition process and its problems, that little attention has been given to developing management training to overcome transition problems, and that much of the training which is offered is largely irrelevant to these problems
Experimental performance of an ablative material as an external insulator for a hypersonic research aircraft
An ablative material composed of silica-filled elastomeric silicone was tested to evaluate its thermal and structural performance as an external insulator, or heat shield, for a hypersonic research aircraft. The material was also tested to determine whether it would form a durable char layer when initially heated and thereafter function primarily as an insulator with little further pyrolysis or char removal. Aerothermal tests were representative of nominal Mach 6 cruise conditions of the aircraft, and additional tests were representative of Mach 8 cruise and interference heating conditions. Radiant heating tests were used to simulate the complete nominal Mach 6 surface-temperature history. The silica char that formed during aerothermal tests was not durable. The char experienced a general and preferential surface recession, with the primary mechanism for char removal being erosion. Tests revealed that radiant heating is not a valid technique for simulating aerodynamic heating of the material
Technical summary of accomplishments made in preparation for the USSR barley exploratory experiment
The highlights of the work accomplished under each subcomponent of the U.S.S.R. Barley Pilot Experiment, which is scheduled for completion in 1984, are summarized. A significant amount of developmental system implementation activity was in the final stages of preparation prior to the rescoping of project tasks. Unpublished materials which are significant to this exploratory experiment are incorporated into the appendixes
Development of a high power microwave thruster, with a magnetic nozzle, for space applications
This paper describes the current development of a high-power microwave electrothermal thruster (MET) concept at the NASA Lewis Research Center. Such a thruster would be employed in space for applications such as orbit raining, orbit maneuvering, station change, and possibly trans-lunar or trans-planetary propulsion of spacecraft. The MET concept employs low frequency continuous wave (CW) microwave power to create and continuously pump energy into a flowing propellant gas at relative high pressure via a plasma discharge. The propellant is heated to very high bulk temperatures while passing through the plasma discharge region and then is expanded through a throat-nozzle assembly to produce thrust, as in a conventional rocket engine. Apparatus, which is described, is being assembled at NASA Lewis to test the MET concept to CW power levels of 30 kW at a frequency of 915 MHz. The microwave energy is applied in a resonant cavity applicator and is absorbed by a plasma discharge in the flowing propellant. The ignited plasma acts as a lossy load, and with optimal tuning, energy absorption efficiencies over 95 percent (based on the applied microwave power) are expected. Nitrogen, helium, and hydrogen will be tested as propellants in the MET, at discharge chamber pressures to 10 atm
