The effect of direction of force to the craniofacial skeleton on the severity of brain injury in patients with a fronto-basal fracture
Abstract The skull base is uniquely positioned to absorb force imparted to the craniofacial skeleton, thereby reducing brain injury. Less well understood is the effect of the direction of force imparted to the craniofacial skeleton on the severity of brain injury. Eighty-one patients from two UK major trauma centres who sustained a fronto-basal fracture were divided into two groups: those struck with predominantly anterior force and those by predominantly lateral force. The first recorded Glasgow Coma Score (GCS), requirement for intubation, and requirement for decompressive craniectomy were used as markers of the severity of brain injury. An average GCS of 5 was found in the lateral group and 14 in the anterior group; this difference was statistically significant ( P
Abstract Using the Stochastic Frontier Approach (SFA) and Data Envelope Analysis (DEA), this study examines the influence of bank efficiencies on the market assessment of bank holding company (BHC) mergers. The following two questions are addressed: (1) Is the target BHC's frontier efficiency reflected in the bidder BHC's abnormal returns? and (2) Does the difference in frontier efficiency between the bidder and/or target banks relative to their peer institutions influence the acquirer's abnormal returns? In support of the Inefficient Management Hypothesis, the findings indicate that bidder wealth effects do incorporate the target's X-efficiency as well as the difference in bidder/target efficiencies relative to their peer institutions.
