Using Positional Data from Vessel Monitoring Systems to Validate the Logbook‐Reported Area Fished and the Stock Allocation of Commercial Fisheries Landings

AbstractStock allocations derived from vessel monitoring system (VMS) positional data from northeastern U.S. fisheries were compared with those obtained from mandatory vessel trip report (VTR) logbooks. A gear‐specific speed algorithm was applied to VMS positions collected in 2005 from otter trawl, Atlantic sea scallop Placopecten magellanicus dredge, sink gill‐net, and benthic longline fisheries to estimate the locations of fishing activity. Estimated fishing locations were used to reallocate the stock area landings of eight federally managed groundfish species. The accuracy of the VMS method relative to that of the mandatory logbooks was assessed using haul locations and catch data recorded by at‐sea observers. The VMS algorithm tended to overestimate the number of statistical areas fished, such that when a trip's fishing activity occurred in a single statistical area, logbooks more accurately reflected the true fishing location. However, when fishing activity occurred in multiple statistical areas, the VMS algorithm showed appreciable gains relative to logbook data. Compared with mandatory logbooks, the VMS method achieved distributions of stock landings closer to observer estimates in 77.8% of the cases examined. The stock allocation percentages from both the VMS‐ and VTR‐based methods were within 1.7% for all stocks, suggesting that the impacts on total stock allocations are relatively minor. However, these small differences represent major relative differences in stock landings for less abundant stocks such as southern New England–Mid‐Atlantic yellowtail flounder Limanda ferruginea, where the VTR‐based method allocated 61.9% more landings than the VMS‐based method. The VMS‐based method is not a replacement for the VTR‐based method; however, it can and should be used as a tool to identify those vessels for which targeted outreach activities would improve the accuracy of VTR statistical area reporting.

Hemingway on the China Front: His WWII Spy Mission with Martha Gellhorn (review)

Reviewed by Kaimei Zheng University of Massachusetts Hemingway on the China Front: His WWII Spy Mission with Martha Gellhorn. By Peter Moreira. Washington, D.C.: Potomac Books, 2006. 244 pp. $26.95. With more than five major Hemingway biographies in print, including Michael Reynolds's monumental work, Hemingway's life is more than an open book to the world. Therefore it's easy to dismiss any attempt to add to that life, let alone another book about Hemingway's three-month trip to China with Martha Gellhorn in 1941. Yet, when I thumbed through Moreira's book with its rich detail and copious references, both its depth and its style and tone drew my attention immediately. Moreira has obviously mined a significant chapter in Hemingway's life that all previous biographers have failed to probe. Hemingway on the China Front is neither a trip report nor a honeymoon journal; Moreira has extended Hemingway's biography significantly. Most of Hemingway's previous biographers used readily available resources such as Martha Gellhorn's book, Travels with Myself and Another, and Hemingway's PM articles collected in By-Line. Moreira, by contrast, sat in the New York Public Library and dug into Gellhorn's Collier's articles from the trip, which give a very different impression than the memories she recorded in Travels with Myself and Another thirty-seven years later. Over the course of ten years, Moreira went from library to library, box to box, from Asia to Europe, digging, weaving, and piecing together the puzzle. Meanwhile, the 2003 publication of Caroline Moorhead's biography of Martha Gellhorn opened another treasure box of information about Hemingway and Gellhorn's life together, including Gellhorn's miserable experience during their China trip and her correspondence about it. Moreira also dug into Hemingway's letters about the trip to Ralph Ingersoll, Maxwell Perkins, and other friends. A journalist by training who lived in Hong Kong for four years, Moreira has first-hand experience in the exact environment where Hemingway and Gellhorn spent a month fifty years earlier. Following Gellhorn's details, Moreira recreates the sensations and the images of the British Colony at the time—the smells, the light, the streets, the hotel itself—he even interviews [End Page 115] the hotel doorman from the period when Hemingway and Gellhorn stayed there. In China itself, Moreira recognizes the place where Hemingway stayed in Chengdu as the same place where Jung Chang, the author of Wild Swans, would live seventeen years later. Moreira not only paints a telling portrait of each person that Hemingway and Gellhorn met during the trip—whether British, Chinese, or American—but also includes a short biography that often leads to another significant figure or event in Sino-American history, wwii history, and/or Chinese modern history. Moreira's delightful, often provocative style carries the reader through the adventure of being in wartime China, and the action in the book is continuous. With his keen eye for details, Moreira takes readers with the Hemingways on a plane ride with a skilled American pilot over Japanese lines and on an unimaginably rough trip on the North River towards the front line. Moreira is the first one to read between the lines of Gellhorn's three publications about the trip, and he provides a telling judgment on her various revisions over time: the Collier's stories (1941), The Face of War (1959), and Travels with Myself and Another (1978). Working with Gellhorn's life and correspondence, Moreira analyzes the psychological path she traveled during those thirty-seven years. This is not only a book about a moment in Hemingway and Gellhorn's life together, it is also a book detailing Chinese history at the time. Moreira unravels several tangled aspects, including the Roosevelt administration's policy towards China during early wwii (particularly the roles of Harry Dexter White and Henry Morgenthau), the history of Chinese Communism and the anti-Communist policy of Chiang Kai-Shek, together...

Instream flows for recreation are closely correlated with mean discharge for rivers of western North America

AbstractEffective river regulation requires consideration for environmental and economic aspects and also for social aspects including recreation. Our study investigated relationships between river hydrology and recreational flows (RF) for canoes, kayaks, rafts and other non‐motorized boats, for 27 river reaches in the Red Deer and Bow river basins of southern Alberta, Canada. A subjective RF method involved regression analyses of data from River Trip Report Cards, volunteer postcard‐style surveys rating flow sufficiency. A total of 958 trip reports were submitted for the rivers between 1983 and 1997 and about 30 reports permitted confident regression analysis for a river reach. Values from these analyses were very consistent with values from the ‘depth discharge method’, a hydraulic modelling approach that used stage–discharge ratings to determine flows that would produce typical depths of 60 and 75 cm for minimal and preferred flows, respectively. Values were also consistent with expert opinions from river guidebooks and maps and aggregate values were calculated from the combined RF methods. These were very closely correlated with mean discharge (Qm) across the rivers (r2 = 0.94 for minimal and 0.96 for preferred flows). The relationship best fitted a power function (straight plot on log versus log scales) with a consistent slope but vertical offset for minimal versus preferred flows. Close relationships between guidebook estimates of RF and Qm were also observed for rivers in the American Rocky Mountain states of Idaho (r2 = 0.55 and 0.74), Montana (r2 = 0.34 and 0.80) and Colorado (r2 = 0.43 and 0.51), but the association was weaker for the Pacific Northwest state of Oregon (r2 = 0.35 and 0.26). These analyses indicate that RF can be confidently determined through a combination of subjective and hydraulic methods and reveal that RF values represent a systematic function of discharge for a broad range of alluvial and constrained river reaches. From these analyses we provide the ‘Alberta equation’: minimal recreational flow = 3 × Qm0.59 (Qm in m3/s), and preferred flows would typically be 1.5 times higher. For other river regions the exponent ‘0.59’ may be relatively constant but adjustments to the coefficient ‘3’ could be applicable. Copyright © 2005 John Wiley & Sons, Ltd.

Interdisciplinary Rapid Field Appraisals

Rapid assessment is a tool to understand and address complex sustainability problems as well as a learning device for education of future professionals who need opportunity to develop their skills. Professionalism involves a four-part skill setcritical thinking, observation, management, and technical concerns-which can be taught in rapid assessment field trips. Our course teaches this four-part skill set through pre-field trip activities (lectures, readings, discussion, exercises, and presentations), the field trip (about 14-days in country) to Central or South America (and elsewhere), and in post-field trip analysis and report preparation. The basic interdisciplinary educational approach is introduced, a list of basic questions to be researched and worksheets are provided, and an outline for writing reports is offered. Readings give explanation of the interdisciplinary approach and illustrate its use worldwide. Reports based on the field trip are published and circulated widely. At the invitation of The Nature Conservancy in Quito, the 2001 course assessed the Condor Bioreserve in Ecuador. Both students and instructors evaluated the interdisciplinary rapid assessment field trip as highly successful. Our problem solving and educational approach has been used in our classroom and in the field, as well as by other people in diverse contexts, to improve both substantive and process outcomes in sustainable natural resources policy and management.

China: CSRC — carbon black

The objective of this study was to use TRACE code to analyze the reactor coolant system pressure transients under LONF ATWS for Maanshan PWR. According to Westinghouse Anticipated Transients Without Trip report, LONF ATWS was considered as the most severe plant condition. The ASME Code Level C service limit criteria of 22.06 MPa (3200 psig) was assumed to be an unacceptable plant condition in SECY-83-293. In accordance with 10 CFR 50.62, Maanshan NPP has established AMSAC. Unlike the reactor trip system, it automatically initiates the auxiliary feedwater system and turbine trip under conditions indicating an ATWS. Since the ATWS analysis is not specified in the FSAR (Taiwan Power Company, 1982), TRACE code was used to assess the RCS pressure for Maanshan NPP. Analysis results indicate that RCS pressure can be maintained within 22.06 MPa with sufficient negative moderator temperature coefficient and normal work of AMSAC and valves.

Compliance with prehospital triage protocols for major trauma patients.

The extent to which severely injured patients receive definitive care at trauma centers is determined by the accuracy of prehospital major trauma criteria in predicting severe injuries and by the level of compliance with these triage instructions by prehospital providers. This study was conducted to evaluate the level of compliance with triage criteria in an established trauma system. The study involved a retrospective analysis of the 1995 Maryland statewide prehospital ambulance data. Prehospital providers in Maryland are instructed to consider transporting patients meeting any of the three nonexclusive major trauma criteria-physiology, injury, and mechanism-to designated trauma centers. Compliance with these criteria was defined as the proportion of patients transported to designated trauma centers among those meeting prehospital triage criteria as documented on the ambulance trip report. Special emphasis was placed on differences in the levels of compliance by age of the trauma patients. A total of 32,950 transports were analyzed. Patients meeting injury criteria were most likely to be transported to trauma centers (86%), followed by those meeting mechanism criteria (46%), and physiology criteria (34%). When the level of compliance was stratified by age, there was no age difference in the level of compliance for patients meeting injury criteria (90.5% for patients aged 0-54 years vs. 88.7% for patients aged 55+ years; p = 0.197). For older patients meeting physiology criteria only or for those meeting mechanism criteria only, however, compliance was differentially low. For patients meeting physiology criteria only, the compliance was 40.3% for patients aged 0 to 54 years and 23.9% for patients aged 55 years and older (p = 0.0001); for patients meeting mechanism criteria only, compliance was 47.0% for patients aged 0 to 54 years and 39.7% for patients aged 55+ years (p = 0.002). The majority of patients meeting prehospital major trauma criteria were transported to designated trauma centers. Patients meeting only physiology criteria, however, were much less likely to be transported to trauma centers, and there was a differentially low compliance for elderly trauma patients meeting physiology criteria alone. The causes and consequences of lower compliance with triage instructions for the elderly population deserve further investigation.

Visual designer's notes

This article reports one visual designer's impressions of the CHI '95 conference, held in Denver, Colorado, from May 7 to 11, 1995. For the readers of this column who are regular conference attendees, I hope to provide glimpses of elements you may have missed. After all, with the frenetic schedule of a CHI conference, what attendee can actually see all they really want to see? And for those of you who were unable to attend this year, especially practitioners in the visual design community who were too busy designing interfaces to attend, I hope to give you a feeling for some of the big themes of this year's CHI, both within and outside the conference program, and to point you toward some of the interesting things you missed.For all readers, this article provides some useful pointers to the CHI '95 Conference Proceedings and the CHI '95 Conference Companion, for details about the notable papers and other presentations included in the conference program. This year's Electronic Proceedings and Companion CD-ROM is particularly complete, containing all the text of the weighty books, as well as accompanying graphics and illustrations, in a format that can be read by any HTML browser on any computer platform.This trip report focuses mostly on visual design related activities at the conference, and as a result isn't a very balanced or comprehensive report of what happened. Rather, this article presents my own selected thoughts and impressions as a sixth-time attendee of the conference and a practicing visual designer in the field of human-computer interaction. I hardly need to add that opinions presented in this article are my own, and do not always jibe with those of my employer, U dot I, Inc.
