Main Effects

The paper examines experimental guessing “p-beauty contest” game. The objective of the study is to conduct an experimental study of simultaneous decision-making by subjects within various groups in the “p-beauty contest” guessing game, and to estimate the influence of various factors. The interac-tion of factors was evaluated. The contribution to this study extends the analysis of simultaneous de-cision-making by individuals within various groups to the conditions of the “p-beauty contest” game. The subjects simultaneously took decisions, while being part of a group of three subjects, and as part of a group of six subjects. The results from the experiment showed that the subjects make more ra-tional decisions, being in the larger group. The four-factor (a p-value, a group size, a period, and num-ber of subjects) experimental design shows that the Factors “p-value” and “Number of subjects” main effects were significant. Further, the Factor “p-value” by Factor “Group size,” the Factor “Group size” by Factor “Period,” the Factor “Group size” by Factor “Number of subjects,” and the Factor “Period” by Factor “Number of subjects” interactions were also significant.

An experimental study was conducted to determine the minimum group size for which the mitigating effect for the hot hand and gambler’s fallacies can be felt. This is quantified by looking if groups are as prone to the hot hand and gambler’s fallacies in making decisions as their individual counter parts. Results suggest that groups maximize their investment returns better than individuals as the former choose to decide on their own more and rely on the experts’ opinions less. Triads are the least biased with the hot hand and gambler’s fallacies and thus are able to make more rational decisions and consequently maximize their investments better than the other treatments.These data allowed us to recognize the benefits of forming investment clubs consisting of three members since their decisions are more likely in line with the profit maximizing strategy in comparison with the decisions made by pairs and individuals.

Predominant Factor

A series of model tests was carried out to determine the distribution of load among piles grouped in sand. The effects of initial sand density, pile roughness, driving order, spacing, and the position of the pile in the group on the load distribution were studied. The results showed that, for small loads, the load distribution was random. As the load increased, the distribution was governed mainly by the driving order, but as the ultimate group load was approached the effect of driving order diminished and the position of the pile in the group became the predominant factor on which the load distribution depended.In general the centre (or centre core) piles of a group carried the greatest proportion of the load at the ultimate group load while the corner piles carried the least proportion. Beyond the ultimate group load, there was a redistribution of the load in such a way that all piles carried an approximately equal share of the load irrespective of their driving order and position. As the spacing was increased, the distribution tended to become independent of both driving order and pile position, and all piles carried an approximately equal share of the load. Initial soil density, pile roughness, and group size were found to affect the total group loads, but had no effect on the load distribution.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
