What’s in a Name? The Dilemma of Title and Geography for Contemporary Hasidism

This paper examines the importance of “branding” in hasidic life. It considers the impact of place names associated with the title of a particular rebbe or tsadik and his followers. When there is more than one claimant to succeed to the role of rebbe for a particular group of hasidim, the competition is often intensified because even though each claimant may have his own followers, there is only one name available for the group and its leader. This situation, different from the one that existed earlier in the history of Hasidism, makes the circumstances of succession today more fraught than they once were.     

Triangulation as splitting in the service of ambivalence

Ambivalence mastery is postulated as a primary dynamic in triangulation, by appealing to splitting and other defense mechanism strategies in synthesizing incompatible affect. The rationale of admissible triangles in balance theory is critically evaluated, and is elaborated in terms of directional vectors and the interpretation of the triangle as a transformed variant of the double bind. Using an illustrative case presentation where an adolescent was instrumental in forming a coalition with his father against an uncle, a theoretical model is developed reconceptualizing various family systems tenets and addressing inconsistencies in hypothesized mechanisms. Ambivalence is analyzed in terms of transference and as a prerequisite of triangulation, the role of the triangulated in relational stability is examined, and the dyad/triad evolution is elaborated. The model is then related to the basic theoretical positions in family systems literature.

The average spearman rank correlation coefficient

A method is derived for finding the average Spearman rank correlation coefficient ofN sets of ranks with a single dependent or criterion ranking ofn items without computing any of the individual coefficients. Procedures for calculating the exact distribution of _av for small values ofN andn are described for the null case. The first four moments about zero of this distribution are derived, and it is concluded that for samples as small asN=4 andn=4 the normal distribution can be used safely in testing the hypothesis _av=0.This problem first came to the writer's attention in discussions with Dr. Dean J. Clyde.     

Categories in the pigeon brain: A reverse engineering approach

Pigeons are well known for their visual capabilities as well as their ability to categorize visual stimuli at both the basic and superordinate level. We adopt a reverse engineering approach to study categorization learning: Instead of training pigeons on predefined categories, we simply present stimuli and analyze neural output in search of categorical clustering on a solely neural level. We presented artificial stimuli, pictorial and grating stimuli, to pigeons without the need of any differential behavioral responding while recording from the nidopallium frontolaterale (NFL), a higher visual area in the avian brain. The pictorial stimuli differed in color and shape; the gratings differed in spatial frequency and amplitude. We computed representational dissimilarity matrices to reveal categorical clustering based on both neural data and pecking behavior. Based on neural output of the NFL, pictorial and grating stimuli were differentially represented in the brain. Pecking behavior showed a similar pattern, but to a lesser extent. A further subclustering within pictorial stimuli according to color and shape, and within gratings according to frequency and amplitude, was not present. Our study gives proof‐of‐concept that this reverse engineering approach—namely reading out categorical information from neural data—can be quite helpful in understanding the neural underpinnings of categorization learning.
