This study aimed to construct a composite model of Dyadic Cofeeding Tolerance (DCT) in zoo-housed bonobos and chimpanzees using a validated experimental cofeeding paradigm and to investigate whether components resulting from this model differ between the two species or vary with factors such as sex, age, kinship and social bond strength. Using dimension reduction analysis on five behavioral variables from the experimental paradigm (proximity, aggression, food transfers, negative food behavior, participation), we found a two-factor model: "Tolerant Cofeeding" and "Agonistic Cofeeding". To investigate the role of social bond quality on DCT components alongside species effects, we constructed and validated a novel relationship quality model for bonobos and chimpanzees combined, resulting in two factors: Relationship Value and Incompatibility.

As early motor performance may be essential for developing later visual-perceptual and visual-motor skills, early motor performance may be associated with PIQ.
Aims: To evaluate whether in preterm born children motor performance at two years was associated with PIQ at eight years.
Objectives: Recently, guided implant surgery has been introduced and several studies verified its accuracy. While those studies reported on the accuracy of the entire procedure, this experiment wanted to evaluate the degree of deviation that can occur during the drilling procedure alone, due to the tolerance of the drill in the sleeve insert.
Material And Methods: Drilling was executed in a plexi-glass box with a maximal inclination of the drills within the sleeve insert.
Objective: To examine the interobserver reliability, internal consistency, and clinical importance of 3 clinical tests for the assessment of scapular positioning in patients with shoulder pain.
Design: Prospective repeated-measures design.
Setting: Private practices for physical therapy and hospital outpatient physical therapy divisions.
