A behavioural technique is described suitable for the treatment of patients with high levels of guilt who attempt to relieve their depression by risk-taking activities which reflect their individual ...wishes and fears, or who suffer anxiety due to unacceptable past behaviour. It is recommended as an alternative brief method of treatment to psychoanalysis and is based on the application of behaviour therapy to a patient's psychopathology. Three case histories are described to illustrate the principles of the technique.
A conceptual design of an angular multiplexed 50 kJ KrF laser module is presented for use as a reactor driver for inertial confinement fusion (ICF). Such multiplexing is one approach to achieve the ...pulse compression needed for an efficient reactor driver. Optical designs are developed with emphasis placed on reducing prepulse problems and achieving acceptable optical quality. An axisymmetric optical design is identified as optimum in terms of simplicity, optical quality, cost, and ease of alignment. A kinetic code model for the KrF amplifier was used to derive scaling maps for the 50 kJ module with acceptable extraction efficiency and accounting for amplified spontaneous emission effects. The size of the module is constrained by parasitic suppression and damage threshold; the power gain is constrained by demanding 40 percent extraction efficiency in a double-pass extraction geometry, and the run time is constrained by the pulsed power technology and acceptable values of g_{0}L . The bounds imposed on the design by the pulsed power technology were examined.
An attempt is made to examine the information content in analysts' recommendations, which are made on a 5-point buy, hold, or sell scale. The data set includes data on 10,000 forecasts per month, and ...it does not suffer from selection or survivorship bias. The data were compiled by the investment group at Banker's Trust Co. Beginning in March 1981, forecast data were collected from 33 brokerage firms. The analysis uses data for the period March 1981-November 1983. The analysis indicates that there is information in brokerage firm recommendations, in that excess returns are found in the month during which there is a change in the brokerage firm recommendations, as well as during the next 2 months. About 4.5% extra return can be earned by purchasing new buys rather than new sells. Buying the brokerage firm list leads to excess returns, but they are not as large as those earned by acting on changes. A superior firm cannot be identified.
