Cisterna chyli: A detailed anatomic investigation
Authors: Loukas Marios , Wartmann Christopher T. , Louis Robert G. , Tubbs R. Shane , Salter E. George , Gupta Ankmalika A. , Curry Brian 
Published: April 2007

AbstractWith recent laparoscopic advancements in retroperitoneal and thoracic surgical procedures, familiarity with major lymphatic structures, such as including the cisterna chyli (CC) and thoracic duct (TD), has proven beneficial in avoiding misdiagnosis and iatrogenic intraoperative injury. In this light, the aim of our study was to explore and delineate the topography of the CC, classify the different patterns of lymphatic tributaries, and categorize its varying location with respect to the vertebral bodies. The anatomy of the CC was examined in 120 adult human cadavers. The CC was found in 83.3% of the specimens and both the tributaries of the CC and the location, with respect to vertebral level, demonstrated wide variation. The results were classified into four types. The most common tributary configuration (type I), found in 45% specimens, was a single CC formed by the union of the left lumbar trunk (LT) and the intestinal trunk (IT). In 30% the CC was formed where the IT opened into the TD and the right lumbar trunk (RT), LT, retroaortic nodes (RN) and branches from the intercostal lymphatics (IL) joined variably (type II). In 20% the CC was formed by the junction of the RT and IT (type III), while in 5% there was a variable confluence pattern of lymphatic trunks that could not be classified (type IV). The CC was located at L1‐L2 (type A) in 63%, T12‐L1 (type B) in 21%, T11‐T12 (type C) in 8%, T10‐11 (type D) in 5%, and T9‐10 (Type E) in 3%, of the specimens. The CC was found in the retrocrural space and, in 75% of the cases, to the right of the abdominal aorta. We hope that the data supplied by this study will provide useful information in the future to anatomists, radiologists and surgeons alike. Clin. Anat. 20:683–688, 2007. © 2007 Wiley‐Liss, Inc.
Mergers and group status: the impact of high, low and equal group status on identification and satisfaction with a company merger, experienced controllability, group identity and group cohesion
Authors: Fischer Peter , Greitemeyer Tobias , Omay Suat Ilkay , Frey Dieter 
Published: March 2007

AbstractAlthough mergers are seen as tools to enhance business in today's global marketplace, they have had a low success rate, possibly because the focus has been on financial and legal issues rather than on the human factors involved. In this respect, focusing on the social psychological variables, social identity theory can provide an explanation for the failure of most mergers. An experiment based on this theory involving mergers between two workgroups was conducted to investigate the effects of merger‐related status on participants' psychological responses to the mergers. Thirty‐six small groups were assigned to three different status groups (high, low and equal status groups) using the minimal group paradigm. Most negative responses to the merger—in terms of identification with the merger group, satisfaction with the merger, common in‐group identity, group cohesion and controllability—were given by the members of the low status groups. Contrary to expectations, status was not related to the performance of the groups. Theoretical and practical implications are discussed. Copyright © 2007 John Wiley & Sons, Ltd.
Deformation by examples: a density flow approach
Authors: Leung Hoi‐Chau , Hui Kin‐Chuen 
Published: April 2007

AbstractIn this article, a shape transformation technique is introduced for deforming objects based on a given deformation example. The example consists of two reference shapes representing two different states of an object. The reference shapes are assumed to morph from one state to the other. The evolution between the two reference shapes determines the shape transformation function. Any given objects can then be deformed by the same transformation. A continuous 4D Radial Basis Function is used to construct a density flow field (an extension of the optical flow in computer vision) representing the shape transformation of the example in 3‐space. Objects embedded in the density flow field are deformed by moving vertices of the objects along the density flow vectors. Additional parameters are introduced to control the process of the deformation. This provides explicit control on the shape of the object obtained in the deformation process.
