Show moreAn experimental investigation is described in which a Pepsios high resolution pressure scanning s pectrometer is used to measure the absorption of light due to atomic sodium in the upper atmospher e. Design and construction of the spectrometer will be discussed with attention given to unique features of the instrument which were develo ped in this study. An attempt is made to see if any dependence on the abundance of the sodium can be accounted for by the proximity to the ocean or by the winds and extreme turbulence developed by tropical storms and hurricanes. It is hoped that this data will compliment the existing data found at other latitudes so that a circulation dependence may be found.

The purpose of this study was to determine the extent to which preadaptation to differential brightness magnitude affects responses to a constant postadaptation stimulus. Twenty-four male albino rats, one hundred and tweny days old, were divided into four groups and differentially preadapted in Skinner-boxes to 236.90, 77.25, 22.87, and 1.27 apparent foot-candles for 10 minutes, without access to a bar.

Twenty-four male albino rats, one hundred and tweny days old, were divided into four groups and differentially preadapted in Skinner-boxes to 236.90, 77.25, 22.87, and 1.27 apparent foot-candles for 10 minutes, without access to a bar. Immediately following this period the Ss were allowed to respond under continuous reinforcement to a postadaptation stimulus of 236.90 apparent foot-candles. Measurement in terms of bar pressing indicated that the four groups extinguished differentially over six days. The control group, for whom the discrepancy bwtween preadaptation magnitude and postadaptation stimulus remained zero, was found most resistant to extiction during this period. Additionally, increases in the discrepancy between the pre- and postadaptation magnitudes led to experimental groups. The implications of these data for the proposition of stimulus definitions in terms of behaviorally effective magnitudes were discussed.

Show moreThe observation of contrast effects (CE) in response to differential relnforcenent has subsequently elicited a diversity of experimental results and theoretical interpretations. Adaptation Level (AL ) concepts have provided a mechanism for integrating such data within a psychophysical frame-of-reference approach. The application of this approach to the somewhat neglected area of response-produced stimuli associated with effort, suggests that proprioceptive stimuli may be effectively evaluated in a simllar manner. Following shifts in the amount of effort required to produce a constant reward magnitude, performance measures demonstrated positive and negative contrast effects (PCE; NCE) in relation to an appropriate control performance. Data analysis suggested that the combined effects of greater effort and shift conditions tended to increase resistance to extinction. The findings are not consistent Kith traditional (e. g., Hull, Spence) concepts with regard to CE and the influence of effort on performance. It is suggested that such effects are more consistent with a contextual, or frame-of- reference, viewpoint.

Pairs were matched accordlng to the number of trials requtred to reach a criterion of 18/20 correct responses then randomly assigned to one of two grouos for testing In transposition. Both groups were tested on the orlgtnally positive stimulus and a brighter one: 1.25 ft/cd for Group 8-C and 5.38 ft/cd for Group 8-D. By testing for transposttlon wtth non-reinforced trials, contrary to the usual method, a tendency toward converging measures of transposltton was achteved. Transposition for Group 8-D, In the situation most dissimilar to training, was greater than for 8-C. These results were discussed from relational or Gestalt, Spence model, and Adaptation Level positions and It was shown that the results are contrary to traditional Gestalt predictions. It was oredlcted that, according to underlying assumptions of the Spence model, with continued non-reinforced trials, per cent of transposition for both groups would decrease until a chance level of responding was reached. That this did not occur cannot be explained by the Spence model. Because the variability was too great with such a small N, these results did not reach the .05 level of probability.

Show moreThis study was a partial replication of one previously reported by Nash and Michels (1966). The purpose was to investigate perceptual form discrimination behavior of young squirrel monkeys as affected by contextual variables of the stimulus. The variables examined were Redundancy, Position and, of the form itself, Complexity. In addition, a sequential method of testing and recording was compared with the conventional 50-trial block procedure. Two 17 month old monkeys were tested on eight twochoice problems in a Purdue General Test Apparatus. The problems each consisted of two slides on which pairs of random shapes were presented. The shapes within each pair of slides were held constant on the parameters investigated. One slide was designated as the positive stimulus and presented in either the right or left position in random order. The number of correct responses for the 50-trial blocks, as examined by an analysis of variance, failed to reach statistical significance for any of the variables investigated. However, graphic inspection of the data suggests general agreement with the findings of Nash and Michels (1966). In comparing the two methods of testing, the sequential test of performance (STOP) was equally as effective as the conventional method and could have provided a substantial savings in test time. Comparison of scores obtained by the two procedures shows good correlation. Although no strong conclusions can be drawn from the data, they do lead to the speculation that there is a relationship between effect and extent of redundancy, and that failure of S to make a correct response in the test situation may be the result of cue sampling rather than a failure to discriminate.

Show moreIn studying Equine Infectious Anemia (EIA), a specific viral disease of Equidae, characterized by intermittent fever, anemia and progressive weakness, questions have arisen as to the existence of a viral hemagglutinin. Raised hemagglutinin levels are present in the infected sera, but this is further complicated by the fact that some horse serums contain relatively high levels of hemagglutinins which are believed to be non-specific natural agglutinins. This investigation, which parallels research currently in progress on the EIA virus proper, is designed to characterize those agglutinins found in non-infected sera. Two principal types of equine hemagglutinins were studied; (1) the natural occurring non-specific blood agglutinin, and (2) hyperimmune isoagglutinins produced in a primary immune response following injection of heterogenic equine erythrocytes. Both species of agglutinins were obtained from whole serum. Standard immunological techniques such as reduction and alkylation, heat inactivation, ion-exchange chromotography, density gradient ultracentrifugation, and electrophoresis were employed in the investigation of structural and biological characteristics of the hemagglutinins. The results have shown that natural equine hemagglutinins are heterospecific. They are sensitive to heat (56°C) and reducing agents such as mercaptoethanol. Natural agglutinins have a sedimentation coefficient of 18.65 and electrophoretically migrate as alpha2 globulins. The hyperimmune isohemagglutinin is a specific antibody reactive with a well defined antigen. It is relatively heat stabile and hemagglutinating activity is reduced with mercaptoethanol. Similarly, the isoagglutinin has the some sedimentation coefficient and electrophoretic mobility as the natural antibody. The isoagglutinin is unique in that it represents a new class of antibody not previously reported.

The pseudobranch of T. carolinus is contrasted with a typical carangid pseudobranch, characterized by O. saurus is thick and heavily vascularized and shows a tendency to atrophy with growth of the fish. The results of bilateral pseudobranchectomy differed between adults and juveniles. All the fish became blind; however, only the adults displayed buoyancy problems and permanent chromatophore expansion.

Show moreThe purpose of this experimental study of the helium afterglow in a hollow cathode discharge is to identify the mechanisms which cause an apparent unequal acoustic modulation of the red and violet wings of observed optical spectrum lines. The unequal red-violet effect is traceable to the fact that curved spectrum lines are formed at the exit slit of a monochromator which is equipped with straight entrance and exit slits. Curved spectrum lines emphasize the red and violet wings differently, depending on the light contributions from different portions of the entrance slit, so that spatial variations in the optical image due to acoustic standing waves show unequal integrated light intensities for the modulation of each wing. Only the central portion of the radial standing wave in the afterglow (Bessel function J (kr) distribution) was explored, and the ratio of the red to violet amplitude calculated as 1 : 1.58 agrees qualitatively with experimental results.

Standardized shake-cultures were grown on cellulose and cellulose derivatives supplemented with NH4N03, tris(hydroxymethyl)aminomethane and yeast extract in artificial sea water (Lyman and Fleming), pH 7.5, at 25 C. Induced C1 and Cx enzyme and cellobiase activities were determined calorimetrically by correlation with cotton fiber weight loss, by the formation of reducing sugars from carboxymethylcellulose and by Glucostat, respectively. Optimum pH values for both Cx enzyme and cellobiase of C. achraspora were 6.0 at 37 C while those for H. mediosetigera (700 LC 1) were 5.0 and 6.0, respectively, at 37 C. In both cultures, Cx enzymes had a variable optimum temperature ( 37-50 C) at pH 6.0, depending on the length of the incubation period, while cellobiases had the same optimum temperature (50 C) at pH 6.0. Thermostability observations on Cx enzyme and cellobiase of C. achraspora showed almost complete deactivation at 100 C in 15 min for the former and 50 C in 15 min for the latter. Thermostability observations on Cx enzyme and cellobiase of H. mediosetigera (700 LC 1) showed almost complete deactivation at 45 C in 15 min for the former and at 50 C in 15 min for the latter. Data indicate that at least three enzymatic functions are involved in cellulose breakdown by these cultures.

The observed band positions have been fitted with the predicted transition energies by the use of the appropriate energy equations for d^3 configuration immersed in tetragonal fields with full configuration interaction. The ligand field parameters, which include the cubic and axial, and the electron correlation parameter B have been evaluated by such a fitting. The derived parameters have been analyzed and their significance discussed. Using thick crystals, we have uncovered a rich doublet structure in some of the complexes and tentative values of the electron correlation parameter C have been obtained for all the complexes.

Show moreEighteen rats were used to study two procedures for the extinction of discriminated avoidance. One group (OE) was placed on extinction defined by presenting shocks as programmed but independently of the S's responses, while the other group (CE) was placed on classical extinction defined by the removal of all shocks. The two procedures were compared in terms of rate of decline and terminal level of extinction performance. In addition, the two groups were placed on a discrimination reversal task in order to assess each procedure's effects on a new learning problem. The CE group reached a lower level of extinction performance in a fewer number of blocks than the OE Ss. Furthermore, the CE Ss were inferior to the OE Ss in terms of discrimination reversal performance as well. An interpretation of the results in terms of the removal and reinstatement of cues was offered although an alternative explanation relating to a change in the motivational states of the two groups during extinction was also presented. The interpretation in terms of the presence or absence of cues seemed to account for more of the present findings than the traditional one advocating changes in motivational levels resulting from the two divergent extinction operations.

This thesis covers a brief description of current problems and the present status of physics courses at the secondary level; a review of standardized programs presently being used; and the necessity for change. The paper will show that a separate program for teaching physics should be instituted below the high school level. It will discuss a means for accomplishing this and propose how this can be done through the use of middle schools or through a change in the continuum.

Both Groups I and II were tested for female sexual behavior. A significant increase in the lordosis response was observed only in Group I Ss after receiving TP-2 plus P-2 every fourth day. Group III Ss were tested for male sexual behavior after receiving DHT-4 daily. Male sexual behavior increased significantly after DHT-4 treatments. It was concluded that progesterone exerts a facilitatory effect on female sexual behavior only when the Ss have been previously primed with an aromatizable androgen and that dihydrotestosterone is capable of inducing male sexual behavior in female rats.

Show moreThis program was developed from necessity found in the teaching of molecular geometry to high school chemistry classes. Recent journals and textbooks were consulted in evaluation of the modern emphasis on instruction in molecular geometry at the high school level, and the topic was then developed fully for use in the chemistry course at the Ransom School, serving as a base for other instructional units. A self-teaching concept was employed in this manual in order that the student might proceed at his own pace and according to his own needs. The principal intention was to familiarize the student with the shapes and configurations of various molecules and thereby to give him greater insight into the physical picture of molecular interaction in chemical reaction.
