Notes: This paper outlines two innovative projects carried out within the same organisation, but with markedly differing results. One has been satisfactorily completed while the other, although having run for much longer, is still experiencing technical problems. The two projects, British Rail's Advanced Passenger Train, and High Speed Train, are examined in relation to the concept of uncertainty. It is suggested that many of the points upon which the projects are differentiated can be attributed to the degree of uncertainty to which they were subject. It is concluded that one means of handling the uncertainty associated with development programmes is to adopt a flexible approach. It is noted, however, that flexibility may not be simply a question of personnel or organisational disposition, but can be influenced by the characteristics of particular projects.

Notes: To examine the relationship between blood pressure (BP) and pulse transit time (PTT) as measured by the time between the ECG R-wave and an associated peripheral pulse, BP was recorded via a radial artery catheter in 3 hvpertensive subjects who underwent a variety of conditions to alter BP. Overall. 70% of the data was usable. Absolute levels of systolic blood pressure (SBP) but not diastolic blood pressure (DBP) were found to correlate appreciably with PTT. There were significant associations between PTT and both SBP and mean BP but not DBP for direction of BP change. With large SBP changes (〉 4 mmHg) an increase in the strength of association occurred in 14 of the 21 conditions across subjects. Overall, PTT did not accurately predict actual BP. PTT and SBP covaried more appreciably in these hypertensives than has been reported for normotensives.

Notes: Summary. In a double blind trial, the effect of prophylactic low-dose subcutaneous heparin or saline on peri-operative blood loss was studied in 100 women undergoing abdominal hysterectomy. Mean blood loss was 401 (SEM 75) ml and 246 (SEM 15) ml in the women who received heparin or saline, respectively. Coagulation studies were carried out during the pre-and post-operative phases in order to assess the contribution of any coagulation abnormalities to operative blood loss. In identifying patients at risk, platelet function tests were of some value.

Notes: Atypical pigment was observed in pre-flexion, flexion and post-flexion larval Sebastes collected off central California in 1991 and 1992 that otherwise resembled Sebastes jordani. Atypical pigment occurred on the axillary region at the base of the pectoral fin (most prominent on the inner edge of the pectoral fin base adjacent to the gut), on the median and distal regions of the pectoral fin and on the median and distal regions of the pelvic fin. In addition, lower and upper jaw pigment was observed at a much smaller size in these specimens than previously described in the literature. Identifications of these atypical specimens as S. jordani were confirmed using meristic and otolith characters as well as mitochondrial DNA sequence data. The ontogenetic variability of S. jordani is described. Specimens collected north of Point Conception were more pigmented than larval S. jordani described in the literature (collected predominately south of Point Conception), suggesting geographic variation in pigment development during the larval stage.

Notes: Four articles have been published in this Journal about the historic cattle trial, Pickett v Tyson Fresh Meats, Inc., in which Plaintiff cattlemen alleged that Tyson/IBP--the buyer--used captive (contracted) supplies of cattle to manipulate the cash market in violation of the 1921 Packers & Stockyards Act (PSA). The first article gave a Trial's eye view by David Domina who served as co-lead counsel representing Plaintiff cattlemen. Domina's article led to a published comment by Thomas Green who was the lead attorney representing Tyson during the Trial phase of lengthy legal proceedings. Green alleged that Domina's article was "littered with rank speculation and baseless opinion." Domina countered that "proof is not litter, and evidence is not rank speculation" and that Green's commentary was "abusive." The adversarial exchange between Domina and Green was followed by another advocacy article in which William Rosales maintained that Pickett "represents an opportunity for the judiciary to reform the meatpacking industry (and) awaken the (PSA's) intended power to dethrone the economic kings of the meatpacking industry."After a five week Trial in Federal Court, the Jury found Tyson/IBP guilty on all counts and assessed actual damages of $1.28 billion over 2/1994 -10/2002. Justice for Plaintiff cattlemen was short, as the Trial Judge set aside the Jury's verdict--a rare but not unprecedented legal action--and entered summary judgment for Tyson. The Eleventh Appellate Court subsequently sided with the Trial Judge. On March 24, 2006, the United States Supreme Court denied without comment Plaintiff's Petition to rehear the case, thus ending legal activities in Pickett v Tyson and effectively killing similar legal action pending against two other major beef packers, Excel (Cargill) and Swift (ConAgra).This article emphasizes three significant and troubling legal and economic issues from the historic litigation: (1) the Courts' narrow and extreme interpretation of the antitrust rule-of-reason; (2) the Courts' endorsement of a "meeting the competition" defense, and (3) whether the Courts inserted themselves above the Jury as fact-finders in the case, contrary to the 7th Amendment to the U.S. Constitution that establishes the Jury as the only fact-finder in civil litigation.In essence Pickett was filed under the Packers and Stockyards Act, tried under Sherman and Clayton antitrust law, and overturned, in part, under the Robinson-Patman Act.
