The present research examined the influences of the halo effect and the similar-tome effect on physical and sexual attractiveness for hiring decisions. It was hypothesized that the halo effect would cause applicants rated highly in physical and sexual attractiveness to receive higher ratings of hireability than unattractive applicants.However, if the similar-to-me effect is influential for levels of attractiveness in hiring situations, participants who rated themselves as less attractive should favor unattractive applicants. The results did not show an interaction between participant self-ratings and ratings of hireability, indicating the similar-to-me effect does not apply to physical or sexual attractiveness. There was a main effect of sexual attractiveness of the applicant forhireability, showing support for the halo effect. This effect was only found for White applicants, potentially due to in-group bias and out-group homogeneity.

The effects of human-structure interaction on the dynamic performance of occupied structures have long been observed. The inclusion of the effects of human-structure interaction is important to ensure that the dynamic response of a structure is not overestimated. Previous observations, both in service and in the laboratory, have yielded results indicating that the effects are dependent on the natural frequency of the structure, the posture of the occupants, and the mass ratio of the occupants to the structure. These results are noteworthy, but are limited in their application,because the data are sparse and are only pertinent to a specific set of characteristics identified in a given study. To examine these characteristics simultaneously and consistently, an experimental test structure was designed with variable properties to replicate a variety of configurations within a controlled setting focusing on the effects of passive occupants. Experimental modal analysis techniques were employed to both the empty and occupied conditions of the structure and the dynamic properties associated with each condition were compared. Results similar to previous investigations were observed, including both an increase and a decrease in natural frequency of the occupied structure with respect to the empty structure, as well as the identification of a second mode of vibration. The damping of the combined system was higher for all configurations. Overall, this study provides a broad data set representing a wide array of configurations. The experimental results of this study were used to assess current recommendations for the dynamic properties of a crowd to analytically predict the effects of human-structure interaction. The experimental results were used to select a set of properties for passive, standing occupants and develop a new model that can more accurately represent the behavior of the human-structure system as experimentally measured in this study.
