Experimental Findings

The present report reviewed the analogue literature on small animal phobias to determine the extent to which researchers employed “blind” experimenters in the assessment of behavioral fear. A total of 87 analogue studies on small animal phobias appearing between January, 1971 and December, 1976 in six professional journals were reviewed. The review showed that only 29% of the studies clearly indicated the employment of “blind” assessors. The results of the review suggest that journal reviewers have been relatively insensitive to this critical design factor and that future research should take the steps necessary to eliminate this major alternative explanation of experimental findings.

Experimental Findings

In the preceding paper the effect of experimental distraction was examined and the findings discussed. The present report is concerned with a similar study of the effect of distraction on tests which involve another aspect of schizophrenic performance, that of psychomotor ability. Earlier studies (Chapman and McGhie, 1961, 1962) produced both clinical and experimental evidence that auditory distraction disrupted the motor responses of some schizophrenic patients. As the previous experimental findings were based on two tests involving only very limited areas of psychomotor performance, it was necessary to examine patients on a wide range of psychomotor tests. A second aim of the present investigation was to assess any differential effects due to variation in the sensory modality of the distracting stimuli.

Aided Design

A competition for teams of three students using a prototype multi-user computer-aided design (MUCAD) tool was held to investigate various hypotheses regarding the performance of teams in such a setting. By comparing models from the competition to the same model in a single-user CAD environment, it is seen that use of a MUCAD system can significantly increase the value-added per unit of calendar time for a modeling effort. An investigation was also made into the causes of the performance differences among the various MUCAD teams which participated in the competition. Analysis of the results shows that teams that encouraged effective forms of communication and teams whose members scored similarly on the Purdue Spatial Visualization Test: Visualization of Rotations (PSVT:R) performed better than other teams. Areas of future research in analyzing teams in MUCAD environments are suggested.

Experimental Findings

Behavioral game theory aims to predict how people actually behave by incorporating psychological elements and learning into game theory. With this goal in mind, experimental findings can be organized into three categories: players have systematic 'reciprocated social values,' like desires for fairness and revenge. Phenomena discovered in studies of individual judgments and choices, like 'framing' and overconfidence, are also evident in games. Strategic principles, like irrelevance of strategy labels and timing of moves, iterated elimination of dominated strategies, and backward induction, are violated. Future research should incorporate these findings, along with learning and 'pregame theory,' into formal game theory.

Concert Halls

This report proposes the stage volume ratio (Vo/V) as an acoustic design factor for concert halls and presents an investigation of the dependence of the acoustic parameters of an auditorium on the stage volume through computer simulation. Firstly, the ratio of the stage volume to the total volume of a concert hall was defined as Vo/V through case studies of existing concert halls. It was verified using a simple model that the stage acoustic parameter STEarly and audience acoustic parameters G and C80 decreased, whereas, the reverberation time and early decay time increased with increasing Vo/V. Secondly, a computer simulation was performed for nine existing concert halls, while changing Vo/V from −20% to 30%. The room acoustic parameters exhibited the same patterns as suggested by the simple model. Vo/V significantly affected the bass ratio and bass index. A comparison of the effects of Vo/V and the sound absorption coefficient in nine concert halls revealed that Vo/V contributed approximately 15% to the reverberation and affected the bass characteristics more substantially. Thus, Vo/V is a critical design factor when determining the warmth of the audience acoustics. The study results could be used as a basis for acoustic design in the future.

Thin metallic shells have long been adopted as major structural components in weight-sensitive applications, especially in marine engineering. Imperfection sensitive buckling is a critical design factor when these structures are loaded in compression. Traditional experimental design method depends on deriving lower bounds to the scatter of large sets of test results. This paper aims to present an analytical approach, the so-called reduced stiffness method (RSM) to the lower-bound buckling of thin-metallic shells. The validity of the RSM for the prediction of the safe lower bounds to the buckling of thin shells is verified through carefully controlled finite element analysis and the comparative studies confirm the reliability of the RSM.

Water Contents

The relationship between molding water content and hydraulic conductivity of a compacted sand-bentonite mixture was examined in a laboratory test program. This program involved triaxial permeability testing of nine specimens of 8% bentonite and Ottawa sand, compacted at standard Proctor density using molding water contents ranging from6 to 19%. The permeability tests were conducted using hydraulic gradients ranging from 19 to 40. The specimens were subjected to an average effective stress during testing of 21 kPa. The tests were conducted using continuous back pressure saturation. Each test was run for a minimum of 40 000 min (approximately 28 days) to enable the flow in and out of the specimen to come to equilibrium with respect to each other. The hydraulic conductivity decreased from 6.5 × 10−9 cm/s for a molding water content of 5.9% to 1.4 × 10−9 cm/s for a molding water content of 15.8%. However, although the hydraulic conductivity was related to the molding water content, the variation in hydraulic conductivity was relatively small. Therefore, the low values reported for all hydraulic conductivity tests suggest that molding water content is not a critical design factor in the construction of a low-permeability sand-bentonite liner. Key words : molding water content, bentonite, liners, hydraulic conductivity, triaxial permeability testing, covers, sand.
