Presentation Time

Subjects were required to discriminate complex random polygons which had the same global shapes but differed in local contour characteristics. Discrimination was most often successful when local contour features comprised a few long line segments or when they were relatively complex. Local contour features of intermediate sized elements and intermediate complexity played a smaller role in discrimination. Presentation time and interstimulus interval effects, and their interaction were observed. A two-factor explanation was offered for the effect of the contour variable.

Candidate Window

To avoid the time-consuming, costly, and expert-dependent traditional assessment of earthquake damaged structures, image-based automatic methods have been developed recently. Since automated recognition of structure elements is the basis by which these methods achieve automatic detection, this study proposes a method to recognize the wall between windows from a single image automatically. It begins from detection of line segments with further selection and linking to obtain longer line segments. The color features of the two sides of each long line segment are employed to pick out line segments as candidate window edges and then label them. Finally, the images are segmented into several subimages, window regions are located, and then the wall between the windows is located. Real images are tested to verify the method. The results indicate that walls between windows can be successfully recognized.

Do So

In Islamic Studies, charisma has usually been reserved for the study of marginalized individuals. I argue here that charisma may also be applied to leadership among legal scholars. To do so, I join a long line of scholars who have modified Max Weber’s initial insights, and put forth a new, dynamic model of charismatic authority. The purpose of my model is to account for the fact that religious histories emphasize the uniqueness of the originating charismatic event, be that Prophet Muhammad’s revelations, Jesus’ theophany or the Buddha’s enlightenment, while at the same time recognizing that the charismatic cycle never quite ends. In contrast with Weber, I argue that charismatic authority in religious traditions is best understood as a network of influence and interaction through which the routinization of charisma reinterprets and redefines the meaning of the originating charismatic event.

Dramatic Shift

We measured the efficiency of 30 participants as they searched through simple line segment stimuli and through a set of complex icons. We observed a dramatic shift from highly variable, and mostly inefficient, strategies with the line segments, to uniformly efficient search behaviour with the icons. These results demonstrate that changing what may initially appear to be irrelevant, surface-level details of the task can lead to large changes in measured behaviour, and that visual primitives are not always representative of more complex objects.
