Contrary to common findings on self-disclosure and gender, male students at a Japanese university that were questioned for this study reported significantly higher disclosure to close friends than their female colleagues-overall as well as for various individual topics (N = 479). Two different measures of self-disclosure were used, both yielding similar results. The gender differences were especially pronounced in cross-gender friendships. In accordance with previous literature, subjective feeling of closeness and respondents’ trust in the stability of the friendship were found to be positively associated with self-disclosure. While both closeness and trust in relationship stability were greater in same-gender friendships, no gender differences were found in this regard. The conclusion discusses the possibility of these findings being connected to shifting images of masculinity and femininity among Japanese youth, as well as changing interaction patterns between genders.

This paper addresses the issues of unstructured terrain modeling for the purpose of navigation with legged robots. We present an improved elevation grid concept adopted to the specific requirements of a small legged robot with limited perceptual capabilities. We propose an extension of the elevation grid update mechanism by incorporating a formal treatment of the spatial uncertainty. Moreover, this paper presents uncertainty models for a structured light RGB-D sensor and a stereo vision camera used to produce a dense depth map. The model for the uncertainty of the stereo vision camera is based on uncertainty propagation from calibration, through undistortion and rectification algorithms, allowing calculation of the uncertainty of measured 3D point coordinates. The proposed uncertainty models were used for the construction of a terrain elevation map using the Videre Design STOC stereo vision camera and Kinect-like range sensors. We provide experimental verification of the proposed mapping method, and a comparison with another recently published terrain mapping method for walking robots.
