Sugar maple decline began to affect Allegheny Plateau forests in the early to mid-1980s. The forests of the region were exposed to several stresses In the period frorn 1985- 1996, including droughts during 1988, 1991, and 1995. Additionally, both native and exotic insects reached epidemic levels during this period (see, for example, Rhoads, 1993). Other documented...

Ground-water levels in Huron County, Michigan, January 1996 through December 1996

Sweat, M.J.

1997-01-01

In 1990, the U.S. Geological Survey (USGS) completed a study of the hydrogeology of Huron County, Michigan (Sweat, 1991). In 1993, Huron County and the USGS entered into an agreement to continue collecting water levels at selected wells throughout Huron County. As part of the agreement, the USGS has provided training and instrumentation for County personnel to measure, on a quarterly basis, the depth to water below the land surface in selected wells. The agreement includes the operation of continuous water-level recorders installed on four wells in Bingham, Fairhaven, Grant and Lake Townships (fig. 1). County personnel make quarterly water-level measurements of 22 other wells. Once each year, County personnel are accompanied by USGS personnel who provide a quality assurance/quality control check of all measurements being made.Precipitation and the altitude of Lake Huron are good indicators of general climatic conditions and, therefore, provide an environmental context for ground-water levels in Huron County. Figure 2 shows the mean monthly water-level altitude of Lake Huron, averaged from measurements made by U.S. Army Corps of Engineers at two sites, and mean monthly precipitation as recorded in Huron County, for the period October 1988 through December 1996. In general, Lake Huron water levels in 1996 were about the same as they were from 1992-94 (NOAA, 1988-96). Precipitation was generally within the normal range, but was lower than 1993 or 1994. Rainfall during May, June, and July was, cumulatively, about 8.5 inches less in 1995 than in 1994.Hydrographs are presented for each of four wells with water-level recorders. Quarterly water-level measurements and range of water levels during 1996 for the other 22 wells are shown graphically and tabulated.In general, water levels in the glaciofluvial aquifer reflect seasonal variations, with maximum depths to water occurring in late summer and early fall and minimum depths to water occurring in late winter and early spring. In general, wells completed in the lower part of the Marshall aquifer continue to show an increase in water-level altitude from the original project period (1988-90); wells completed in the upper part of the Marshall aquifer showed little variation in water-level altitudes compared to previous years. Wells completed in the Saginaw aquifer continued to show higher water level altitudes in 1995, not only near the lake but also farther inland, while water-level altitudes in wells completed in the Coldwater confining unit showed a small increase from the original project period. Water-level altitudes were higher in the southwest and central parts of the County during 1995 than in the previous year, and water-level altitudes were for the most-part unchanged in the northwest, northeast, and southeast parts of the county during 1995. All wells with recorders had lower water levels in September 1995 than in 1993-94. Lower than average precipitation during May-August is the primary reason for lower levels.

Absent for several decades, the chancroid reappeared in Algeria in 1988. In the unique department of Dermatology and Venereology of the University Hospital of the country of Tlemcen (more than 700,000 inhabitants), we wanted to know the state of this STD seven years after the report of the first cases. The file of the consulting patients were examined. We looked for the principal characteristics of this STD: age, sex, incubation period, place infection contact, type of relation, clinical presentation, evolution without and with treatment, other associated STD (syphilis, HIV). From August 1988 (1st case) to December 1995, 144 cases of chancroid were collected = 1988: 6, 1989: 5, 1990: 7, 1991: 18, 1992: 11, 1993: 33, 1994: 48, 1995: 16. The presentation is quite stereotyped; it concerns males only, singles in must cases, having had sexual relations with prostitutes. The incubation period is short (less than 10 days), the characteristic ulceration presents, very often, some adenopathies. The treatment by cotrimoxazole is efficient. They are no concomitant syphilis or HIV infection. The chancroid is the first cause of genital ulceration in the world. Since 1991, it is the principal STD in our department. It spreads within a male population, young singles associated with prostitutes. It is well installed in Algeria, and its role, although minor, in the transmission of the HIV infection, should not be neglected.

Dissolved-solids contribution to the Colorado River from public lands in southeastern Nevada, through September 1993

Westenburg, C.L.

1995-01-01

The Bureau of Land Management administers about 9,300 square miles of public lands in southeastern Nevada that are part of the Colorado River Basin. The U.S. Geological Survey, in cooperation with the Bureau of Land Management, began a 5-year program in October 1988 to assess the contribution of dissolved solids to the fiver from those lands. About 6,200 square miles of public lands are in the Muddy River subbasin in Nevada. The estimated average dissolved-solids load contributed to the Colorado River from those lands was 28,000 tons per year from October 1988 through September 1993. Subsurface flow contributed about 86 percent (24,000 tons per year) of that load. About 730 square miles of public lands in the Las Vegas Wash subbasin contribute dissolved-solids load to the Colorado River. (About 120 square miles of public lands do not contribute to the river.) The estimated average dissolved-solids load contributed to the river from those lands was about 1,300 tons per year from October 1988 through September 1993. Subsurface flow contributed almost all of that load. About 1,100 square miles of public lands are in the Virgin River subbasin in Nevada. The estimated average dissolved- solids load contributed to the Colorado River from Nevada public lands in the subbasin was 8,700 tons per year. Subsurface flow contributed almost the entire load. About 1,200 square miles of Nevada public lands are in ephemeral tributaries that drain direcfly to the Colorado River or its impoundments (Lake Mead and Lake Mobave). The estimated average dissolved-solids load contributed to the river from those lands was 50 tons per year from surface runoff; however, the dissolved-solids load contributed by subsurface flow was not estimated. From October 1992 to September 1993, the Colorado River carried about 6,600,000 tons of dissolved solids past a streamflow gaging station 0.3 mile downstream from Hoover Dam. In contrast, surface runoff and subsurface flow contribute an estimated average dissolved-solids load of 38,000 tons per year from public lands in southeastern Nevada to the Colorado River. Land-management practices probably would not substantially reduce this contribution.

The objective of this study was to assess the relationship between exposure to state-sponsored anti-tobacco advertising and smoking cessation. Cessation rates in 2001 among a cohort of 2061 smokers who participated in the Community Intervention Trial for Smoking Cessation between 1988 and 1993 and completed a follow-up survey in 2001 were merged with the 2000-01 television advertising exposure data from Nielsen Media Research. The relative risk for quitting was estimated to be 10% higher for every 5000 units of exposure to state anti-tobacco television advertising over the 2-year period, although this did not quite achieve statistical significance. The association was even larger among those who reported that the level of information in the media about the dangers of smoking had increased 'a lot' between 1993 and 2001 (RR = 1.19, 95% CI = 1.03-1.38). These data are consistent with the finding that increased exposure to state anti-tobacco media increases smoking cessation rates.

2013-01-01

To present problems and opportunities related to the operating procedures developed by the Tuscan epidemiological surveillance system on mesothelioma during its 25 years of activity. All 1,224 mesotheliomas, registered up to 31.12. 2011, diagnosed in Tuscan residents during 1988-2009 by the Tuscan Operating Centre of the Italian registry, have been considered. In order to evaluate accuracy and completeness of cases, the following indicators by period are used for pleural mesotheliomas diagnosed during 1988-2009: the distribution of the sources of cases' diagnosis and report to the regional registry, the latency time between diagnosis and report, the age and sex specific rates, the ratio between standardized mortality and incidence rates. The distribution of type of interview and exposure classification by period for all cases were used to evaluate the collected and classified exposure information. Histology with immunohistochemistry became the chosen method (97.4% of histological cases in 2005- 2009). Since the second half of the Nineties, other Italian regional Operating Centres and, more recently, the Workers Compensation Authority (INAIL) became new important sources of case report. Nowadays, the mortality/incidence ratio is closer to 1. The latency time between diagnosis and case report have been reducing with a consequent increase in direct interviews to cases (from 20.3% in 1988-1993 to 71.4% in 2005-2009) and in exposure information and classification quality. The regional network with the effective cooperation of the Local Health Authorities produced relevant improvements in the quality of the epidemiological surveillance system. It is hoped that the new revision of the national Guidelines will succeed in taking into consideration all the improvements made by the surveillance system in order to get over the difficulties observed in defining and classifying cases and their asbestos exposure.

To identify which statistical tests are applied in German radiological publications, to what extent their use has changed during the last decade, and which factors might be responsible for this development. The major articles published in "ROFO" and "DER RADIOLOGE" during 1988, 1993 and 1998 were reviewed for statistical content. The contributions were classified by principal focus and radiological subspecialty. The methods used were assigned to descriptive, basal and advanced statistics. Sample size, significance level and power were established. The use of experts' assistance was monitored. Finally, we calculated the so-called cumulative accessibility of the publications. 525 contributions were found to be eligible. In 1988, 87% used descriptive statistics only, 12.5% basal, and 0.5% advanced statistics. The corresponding figures in 1993 and 1998 are 62 and 49%, 32 and 41%, and 6 and 10%, respectively. Statistical techniques were most likely to be used in research on musculoskeletal imaging and articles dedicated to MRI. Six basic categories of statistical methods account for the complete statistical analysis appearing in 90% of the articles. ROC analysis is the single most common advanced technique. Authors make increasingly use of statistical experts' opinion and programs. During the last decade, the use of statistical methods in German radiological journals has fundamentally improved, both quantitatively and qualitatively. Presently, advanced techniques account for 20% of the pertinent statistical tests. This development seems to be promoted by the increasing availability of statistical analysis software.

Changes in atmospheric circulation patterns affect midcontinent wetlands sensitive to climate

USGS Publications Warehouse

LaBaugh, J.W.; Winter, T.C.; Swanson, G.A.; Rosenberry, D.

1996-01-01

Twenty-seven years of data from midcontinent wetlands indicate that the response of these wetlands to extremes in precipitation-drought and deluge-persists beyond the extreme events. Chemical changes transcend such simple relations as increased salinity during dry periods because drought provides mechanisms for removal of salt by deflation and seepage to groundwater. Inundation of vegetation zones including rooted or floating mats of cattail (Typha glauca) can stimulate sulfate reduction and shift the anion balance from sulfate to bicarbonate dominance. Disruptions in the circulation of moisture-laden air masses over the midcontinent, as in the drought of 1988 and the deluge of 1993, have a major effect on these wetlands, which are representatives of the primary waterfowl breeding habitat of the continent.

2011-09-01

Although survey results measuring the safety of consumers' food handling and risky food consumption practices have been published for over 20 years, evaluation of trends is impossible because the designs of published studies are not comparable. The Food Safety Surveys used comparable methods to interview U.S. adults by telephone in 1988, 1993, 2001, 2006, and 2010 about food handling (i.e., cross-contamination prevention) and risky consumption practices (eating raw or undercooked foods from animals) and perceived risk from foodborne illness. Sample sizes ranged from 1,620 to 4,547. Responses were analyzed descriptively, and four indices measuring meat, chicken, and egg cross-contamination, fish cross-contamination, risky consumption, and risk perceptions were analyzed using generalized linear models. The extent of media coverage of food safety issues was also examined. We found a substantial improvement in food handling and consumption practices and an increase in perceived risk from foodborne illness between 1993 and 1998. All indices were stable or declined between 1998 and 2006. Between 2006 and 2010, the two safe food handling practice indices increased significantly, but risk perceptions did not change, and safe consumption declined. Women had safer food handling and consumption practices than men. The oldest and youngest respondents and those with the highest education had the least safe food handling behaviors. Changes in safety of practices over the survey years are consistent with the change in the number of media stories about food safety in the periods between surveys. This finding suggests that increased media attention to food safety issues may raise awareness of food safety hazards and increase vigilance in food handling by consumers.

The focus of this report is on North American wet deposition temporal patterns from 1979 to 1988 and spatial patterns for 1988. It is the third in a series of reports that investigate the patterns of annual precipitation-weighted average concentration and annual deposition for nine ion species: hydrogen, sulfate, nitrate, ammonium, calcium, chloride, sodium, potassium, and magnesium. Mosaic maps, based on surface estimation using kriging, display concentration and deposition spatial patterns of pH, hydrogen, sulfate, nitrate, ammonium, and calcium ion species for 1988 annual, winter, and summer periods. Temporal pattern analyses use a subset of 35 sites over a 10-yearmore » (1979--1988) period and an expanded subset of 137 sites, with greater spatial coverage, over a 7-year (1982--1988) period. The 10-year period represents the longest period with wet deposition monitoring data available that has a sufficient number of sites with data of known quality to allow a descriptive summary of annual temporal patterns. Sen's median trend estimate and Kendall's seasonal tau (KST) test are calculated for each ion species concentration and deposition at each site in both subsets.« less

Atmospheric CO2 Records from Sites in the Main Geophysical Observatory Air Sampling Network (1983 - 1993)

Air samples were collected from five sites in the Main Geophysical Observatory air sampling network to monitor the atmospheric CO2 from 1983 - 1993. Airwas collected generally four times per month in pairs of 1.5-L stainless steel electropolished flasks with one greaseless stainless steel stopcock. Sampling was performed by opening the stopcock of the flasks, which have been evacuated at the central laboratory at the Main Geophysical Observatory (MGO). The air was not dried during sample collection. Attempts were made to obtain samples when the wind speed was >5 m/s and the wind direction corresponded to the predetermined "clean air" sector. The period of record at Bering Island is too short to identify any long-term trends in atmospheric CO2 concentrations; however, the yearly mean atmospheric CO2 concentration at Bering Island rose from approximately 346 parts per million by volume (ppmv) in 1986 to 362.6 ppmv in 1993. Measurements from this station are considered indicative of maritime air masses. The period of record at Kotelny Island is too short to identify any long-term trends in atmospheric CO2 concentrations; however, the yearly mean atmospheric CO2 concentration at Kotelny Island rose from 356.08 parts per million by volume (ppmv) in 1988 to 358.8 ppmv in 1993. Because Kotelny Island is the northernmost Russian sampling site, measurements from this site serve as a useful comparison to other northern sites (e.g., Alert, Northwest Territories). In late 1989, air sampling began at the Russian site of Kyzylcha, located in the Republic of Uzbekistan. Unfortunately, the desert site at Kyzylcha has been out of operation since mid-1991 due to financial difficulties in Russia. The annual mean value of 359.02 parts per million by volume (ppmv) for 1990, the lone full year of operation, is higher than measurements from other monitoring programs at this latitude [e.g., Niwot Ridge (354.7 ppmv in 1990) and Tae-ahn Peninsula]. Station "C," an open ocean site, in the North Atlantic, east of Greenland, was established in 1968 and was operated in cooperation with NOAA's National Weather Service through 1973. The Main Geophysical Observatory collected flask samples at the site from January 1983 through October 1990. The yearly mean atmospheric CO concentration at Station "C" rose from 348.15 parts per million by volume (ppmv) in 1985 to 354.33 ppmv in 1989. The period of record at Teriberka Station is too short to identify any long-term trends in atmospheric CO2 concentrations; however, the yearly mean atmospheric CO2 concentration at Teriberka Station rose from 354.8 parts per million by volume (ppmv) in 1989 to 358.7 ppmv in 1993.

These results showed that the environmental situation, estimated by using the frequencies of micronucleated cells, was stable-there wasmore » no obvious chromosome damage in the animals studied. It was found that the incidence of micronucleated cells of Bivalves was higher than that of Fish and Amphibia, suggesting the epithelial cells to be more sensitive than peripheral erythrocytes to environmental genotoxic effects. The results of our studies for other spots will be reported afterward. These data can be used as the original background information to monitor the environment when the Nuclear Power Station is in operation.« less

To examine the costs and outcomes of infertility-related services in Massachusetts during a time of expanded use of assisted reproductive technology (ART). Cost data were obtained from the Massachusetts Department of Insurance Rate-Setting Commission and 9 large group insurance plans for the period 1986-1993. Utilization and success rates of ART were examined, and the cost per live delivery with the use of ART in 1993 was estimated. The state of Massachusetts, in which access to infertility-related services has been mandated by law since 1989. The study population consisted of 8 large health maintenance organization plans and the Blue Cross/Blue Shield indemnity plan. None. Per capita infertility-related expenditures, infertility-related expenditures as a percentage of total expenditures, live deliveries per initiated ART cycle, and cost per live delivery. Expenditures for infertility services increased at a rate similar to or slower than inflation during the years 1988-1992. Increases were slowest in health maintenance organizations, probably as a result of provider arrangements. Infertility services accounted for 0.41% of total expenditures within the indemnity plan in 1993 (approximately $1.71 per contract-month). Examination of ART utilization showed no evidence of overutilization by patients with a low chance of success. The cost per live delivery with the use of ART in 1993 was $59,484. Mandated infertility coverage was associated with increased use of ART but not with excessive increases in consumer cost for infertility insurance coverage.

Depression research methodologies in the Journal of Personality and Social Psychology: a review and critique.

1995-05-01

Personality and social psychological studies of depression and depressive phenomena have become more methodologically sophisticated in recent years. In response to earlier problems in this literature, investigators have formulated sound suggestions for research designs. Studies of depression published in the Journal of Personality and Social Psychology (JPSP) between 1988 and 1993 were reviewed to evaluate how well these recommendations have been followed. Forty-one articles were examined for adherence to 3 suggestions appearing consistently in the literature: (a) multiple assessment periods, (b) multiple assessment methods, and (c) appropriate comparison groups. The studies published in JPSP have not adhered well to these standards. The authors recommend resetting minimum methodological criteria for studies of depression published in the premier journal in personality and social psychology.

Redd counts are routinely used to document the spawning distribution of fall Chinook salmon (Oncorhynchus tshawytscha) in the Snake River basin upriver of Lower Granite Dam. The first reported redd counts were from aerial searches conducted intermittently between 1959 and 1978 (Irving and Bjornn 1981, Witty 1988; Groves and Chandler 1996)(Appendix 1). In 1986, the Washington Department of Fish and Wildlife began an annual monitoring program that, in addition to the Snake River, included aerial searches of the Grande Ronde River the first year (Seidel and Bugert 1987), and the Imnaha River in subsequent years (Seidel et al. 1988; Bugertmore » et al. 1989-1991; Mendel et al. 1992). The U. S. Fish and Wildlife Service and Idaho Power Company began contributing to this effort in 1991 by increasing the number of aerial searches conducted each year and adding underwater searches in areas of the Snake River that were too deep to be searched from the air (Connor et al. 1993; Garcia et al. 1994a, 1994b, 1996-2005; Groves 1993; Groves and Chandler 1996). The Nez Perce Tribe added aerial searches in the Clearwater River basin beginning in 1988 (Arnsberg et. al 1992), and the Salmon River beginning in 1992. Currently searches are conducted cooperatively by the Nez Perce Tribe, Idaho Power Company, and U.S. Fish and Wildlife Service. Our objective for this report was to consolidate the findings from annual redd searches into a single document, containing detailed information about the searches from the most recent spawning season, and summary information from previous years. The work conducted in 2005 was funded by the Bonneville Power Administration and Idaho Power Company.« less

In 1986, the Washington Department of Fish and Wildlife began an annual monitoring program that, in addition to the Snake River, included aerial searches of the Grande Ronde River the first year (Seidel and Bugert 1987), and the Imnaha River in subsequent years (Seidel et al. 1988; Bugert etmore » al. 1989-1991; Mendel et al. 1992). The U. S. Fish and Wildlife Service and Idaho Power Company began contributing to this effort in 1991 by increasing the number of aerial searches conducted each year and adding underwater searches in areas of the Snake River that were too deep to be searched from the air (Connor et al. 1993; Garcia et al. 1994a, 1994b, 1996-2001; Groves 1993; Groves and Chandler 1996). The Nez Perce Tribe added aerial searches in the Clearwater River basin beginning in 1988 (Arnsberg et. al 1992) and the Salmon River beginning in 1992. Currently searches are conducted cooperatively by the Nez Perce Tribe, Idaho Power Company, and U. S. Fish and Wildlife Service. Our objective for this report was to consolidate the findings from annual redd searches into a single document containing detailed information about the searches from the most recent spawning season, and summary information from previous years.

Raptors are generally considered solitary predators (Schoener 1969), but occasionally they interact socially (Brown and Amadon 1968). Certain raptor species (e.g., Swallow-tailed Kites [Elanoides forficatus] and Swainson's Hawks [Buteo swainsoni]) concentrate in aggregations in response to localized, abundant food sources (Ellis et al. 1993). Many raptor species engage in group hunting (Ellis et al. 1993), and social foraging is a routine strategy for some species (e.g., Harris's Hawks [Parabuteo unicinctus]; Bednarz 1988, Ellis et al. 1993]. Raptors generally engage in group hunting to pursue elusive or large prey (Ellis et al. 1993). Occasionally individuals of conspecific raptors engage in play as a group sometimes involving chases of prey species (Palmer 1988). In this letter, we report interactions between a large group of Golden Eagles and a herd of adult and juvenile Rocky Mountain elk (Cervus canadensis nelsoni) in late autumn.

The focus of this report is on North American wet deposition temporal patterns from 1979 to 1988 and spatial patterns for 1988. It is the third in a series of reports that investigate the patterns of annual precipitation-weighted average concentration and annual deposition for nine ion species: hydrogen, sulfate, nitrate, ammonium, calcium, chloride, sodium, potassium, and magnesium. Mosaic maps, based on surface estimation using kriging, display concentration and deposition spatial patterns of pH, hydrogen, sulfate, nitrate, ammonium, and calcium ion species for 1988 annual, winter, and summer periods. Temporal pattern analyses use a subset of 35 sites over a 10-yearmore » (1979--1988) period and an expanded subset of 137 sites, with greater spatial coverage, over a 7-year (1982--1988) period. The 10-year period represents the longest period with wet deposition monitoring data available that has a sufficient number of sites with data of known quality to allow a descriptive summary of annual temporal patterns. Sen`s median trend estimate and Kendall`s seasonal tau (KST) test are calculated for each ion species concentration and deposition at each site in both subsets.« less

Pioneer Venus data analysis for the retarding potential analyzer

NASA Technical Reports Server (NTRS)

Knudsen, William C.

1993-01-01

This report describes the data analysis and archiving activities, analysis results, and instrument performance of the orbiter retarding potential analyzer (ORPA) flown on the Pioneer Venus Orbiter spacecraft during the period, Aug. 1, 1988 to Sept. 30, 1993. During this period, the periapsis altitude of the Orbiter spacecraft descended slowly from 1900 km altitude, at which altitude the spacecraft was outside the Venus ionosphere, to approximately 130 km altitude in Oct. 1992 at which time communication with the spacecraft ceased as a result of entry of the spacecraft into the Venus atmosphere. The quantity of ORPA data returned during this reporting period was greatly reduced over that recovered in the previous years of the mission because of the reduced power capability of the spacecraft, loss of half of the onboard data storage, and partial failure of the ORPA. Despite the reduction in available data, especially ionospheric data, important scientific discoveries resulted from this extended period of the Pioneer Venus mission. The most significant discovery was that of a strong solar cycle change in the size of the dayside ionosphere and the resulting shutoff of flow of dayside ions into the nightside hemisphere. The large, topside O+ F2 ionospheric layer observed during the first three years of the Pioneer Venus mission, a period of solar cycle maximum activity, is absent during the solar cycle minimum activity period.

To measure the uptake of first invitation to cervical screening by vaccine status in a population-based cohort offered HPV immunisation in a national catch-up campaign. A retrospective observational study of routinely collected data from the Scottish Cervical Screening Programme. Data were extracted and linked from the Scottish Cervical Call Recall System, the Scottish Population Register and the Scottish Index of Multiple Deprivation. Records from 201 023 women born between 1 January 1988 and 30 September 1993 were assessed. Women born in or after 1990 were eligible for the national catch-up programme of HPV immunisation. Attendance for screening was within 12 months of the first invitation at age 20 years. There was a significant decline in overall attendance from the 1988 cohort to the 1993 cohort with the adjusted attendance ratio of the 1988 cohort being 1.49 times (95% CI 1.46-1.52) that of the 1993 cohort. Immunisation compensated for this decrease in uptake with unvaccinated individuals having a reduced ratio of attendance compared with those fully vaccinated (RR=0.65, 95% CI 0.64-0.65). Not taking up the opportunity for HPV immunisation was associated with an attendance for screening below the trend line for all women before the availability of HPV immunisation. HPV immunisation is not associated with the reduced attendance for screening that had been feared. Immunised women in the catch-up cohorts appear to be more motivated to attend than unimmunised women, but this may be a result of a greater awareness of health issues. These results, while reassuring, may not be reproduced in routinely immunised women. Continued monitoring of attendance for the first smear and subsequent routine smears is needed.

The 1995 revision of the joint US/UK geomagnetic field models. II: Main field

Quinn, J.M.; Coleman, R.J.; Macmillan, S.; Barraclough, D.R.

1997-01-01

This paper presents the 1995 main-field revision of the World Magnetic Model (WMM-95). It is based on Project MAGNET high-level (??? 15,000 ft.) vector aeromagnetic survey data collected between 1988 and 1994 and on scalar total intensity data collected by the Polar Orbiting Geomagnetic Survey (POGS) satellite during the period 1991 through 1993. The spherical harmonic model produced from these data describes that portion of the Earth's magnetic field generated internal to the Earth's surface at the 1995.0 Epoch. When combined with the spherical harmonic model of the Earth's secular variation described in paper I, the Earth's main magnetic field is fully characterized between the years 1995 and 2000. Regional magnetic field models for the conterminous United States, Alaska and, Hawaii were generated as by-products of the global modeling process.

Seismic reflection and refraction data were collected in generally ice-covered waters of the Canada Basin and the eastern part of the Chukchi Continental Borderland of the Amerasia Basin, Arctic Ocean, during the late summers of 1988, 1992, and 1993. The data were acquired from a Polar class icebreaker, the U.S. Coast Guard Cutter Polar Star, using a seismic reflection system designed by the U.S. Geological Survey (USGS). The northernmost data extend to 78? 48' N latitude. In 1988, 155 km of reflection data were acquired with a prototype system consisting of a single 195 cubic inch air gun seismic source and a two-channel hydrophone streamer with a 150-m active section. In 1992 and 1993, 500 and 1,900 km, respectively, of seismic reflection profile data were acquired with an improved six air gun, 674 to 1303 cubic inch tuned seismic source array and the same two-channel streamer. In 1993, a 12-channel streamer with a 150-m active section was used to record five of the reflection lines and one line was acquired using a three air gun, 3,000 cubic inch source. All data were recorded with a DFS-V digital seismic recorder. Processed sections feature high quality vertical incidence images to more than 6 km of sub-bottom penetration in the Canada Basin. Refraction data were acquired with U.S. Navy sonobuoys recorded simultaneously with the seismic reflection profiles. In 1988 eight refraction profiles were recorded with the single air gun, and in 1992 and 1993 a total of 47 refraction profiles were recorded with the six air gun array. The sonobuoy refraction records, with offsets up to 35 km, provide acoustic velocity information to complement the short-offset reflection data. The report includes trackline maps showing the location of the data, as well as both digital data files (SEG-Y) and images of all of the profiles.

This essay is a history and analysis of the steps leading to the origins of the space station partnership between the United States and its closest allies. It traces the process that led to the decision to invite other countries to participate in the project and their reasons for accepting that invitation. Not covered in this account are the difficult negotiations during the 1984-1988 period that led first to an initial set of agreements that allowed the prospective partners to work together during the early stages of the space station program and then to the final set of agreements creating the original space station partnership. Also, the 1993 invitation to the Russian Federation to join the original partners is not discussed, nor are the subsequent negotiations to revise the 1988 agreements.

This paper, which is divided into parts I and II, describes the physical aspects of work on total-body irradiation (TBI) at the Middlesex Hospital, London, from 1988 to 1993. Irradiation is fractionated and bi-lateral with horizontal accelerator photon beams of 8 MV (1988-1992) at a source-surface distance (SSD) of 3.36 m and 10 MV (1992-1993) at an SSD of 4.62 m. The main aims were maximum patient comfort, a simple, accurate set-up with overall times per fraction of 30 min or less, dose homogeneity throughout the body within +/- 10 to +/- 15%, pre-irradiation treatment planning on nine CT slices using our commercial IGE RTplan (1988-1992) and Target 2 (1992-1993) treatment planning systems and, most important, verification of the plans by in vivo dosimetry to within +/- 5%. Verification of the planned lung doses, which are distributed over five CT slices, was given special attention. In part I of this paper we describe the preliminary work, most of which was done prior to patient treatment. This consisted of standard dosimetric measurements (central axis depth doses, beam profiles at several depths, build-up and build-down curves, beam output calibrations, effect of body compensators, etc), in evaluating silicon diode dosimeters for in vivo dosimetry and of adapting and verifying the methods of treatment planning for TBI conditions. The results obtained with phantoms, including a Rando body phantom, showed that, in principle, our aims could be achieved. The final proof depended, however, on an analysis of the results of the in vivo work and this forms the subject of part II of this paper.

Peña, R; Wall, S; Persson, L A

2000-01-01

OBJECTIVES: This study assessed the effect of poverty and social inequity on infant mortality risks in Nicaragua from 1988 to 1993 and the preventive role of maternal education. METHODS: A cohort analysis of infant survival, based on reproductive histories of a representative sample of 10,867 women aged 15 to 49 years in León, Nicaragua, was conducted. A total of 7073 infants were studied; 342 deaths occurred during 6394 infant-years of follow-up. Outcome measures were infant mortality rate (IMR) and relative mortality risks for different groups. RESULTS: IMR was 50 per 1000 live births. Poverty, expressed as unsatisfied basic needs (UBN) of the household, increased the risk of infant death (adjusted relative risk [RR] = 1.49; 95% confidence interval [CI] = 1.15, 1.92). Social inequity, expressed as the contrast between the household UBN and the predominant UBN of the neighborhood, further increased the risk (adjusted RR = 1.74; 95% CI = 1.12, 2.71). A protective effect of the mother's educational level was seen only in poor households. CONCLUSIONS: Apart from absolute level of poverty, social inequity may be an independent risk factor for infant mortality in a low-income country. In poor households, female education may contribute to preventing infant mortality. PMID:10630139

Infant Mortality and Income in 4 World Cities: New York, London, Paris, and Tokyo

Objectives. We investigated the association between average income or deprivation and infant mortality rate across neighborhoods of 4 world cities. Methods. Using a maximum likelihood negative binomial regression model that controls for births, we analyzed data for 1988–1992 and 1993–1997. Results. In Manhattan, for both periods, we found an association (.05% significance level) between income and infant mortality. In Tokyo, for both periods, and in Paris and London for period 1, we found none (5% significance level). For period 2, the association just missed statistical significance for Paris, whereas for London it was significant (5% level). Conclusions. In stark contrast to Tokyo, Paris, and London, the association of income and infant mortality rate was strongly evident in Manhattan. PMID:15623865

Use of mini-refuges by female northern pintails wintering in southwestern Louisiana

USGS Publications Warehouse

Cox, Robert R.; Afton, Alan D.

1998-01-01

The Gulf Coast Joint Venture of the North American Waterfowl Management Plan began contracting private agricultural lands (hereafter mini-refuges) in 1988 to expand existing sanctuaries for northern pintails (Anas acuta) in southwestern Louisiana. Previous research suggested that mini-refuges may prove more attractive to pintails than permanent, open-water pools (pools) on refuges because mini-refuges provide sanctuary and food during the day, whereas pools generally provide only sanctuary (Rave and Cordes 1993). We used radiotelemetry to compare diel use of mini-refuges and pools (Lacassine Pool and Amoco Pool) by female pintails in southwestern Louisiana during winters of 1991-1992 and 1992-1993. We examined variation in use of these areas in relation to female age (immature or adult), time period (prehunting season, first hunting season, time between split hunting seasons, second hunting season, and posthunting season), and winter (1991-1992 and 1992-1993). Diurnal use of min-refuges and pools differed among time periods, but differences were not consistent between winters. Mini-refuges accounted for <2% of diurnal use by pintails in 7 of 10 time-period and winter comparisons. Diurnal use of mini-refuges was lower than that of Lacassine Pool in 8 of 10 time-period and winter comparisons. Diurnal use of mini-refuges was lower than tha of Amoco pool during first hunting season in 1992-1993, but use of these areas did not differ within other time periods and winters. Nocturnal use of mini-refuges and pools did not differ in relation to female age, time period, winter, or individual bird. Nocturnal use of mini-refuges did not differ from that of Lacassine Pool. In contrast to predictions and findings by Rave and Cordes (1993), we found that: (1) female pintails did not use mini-refuges more than pools, and (2) female pintails used mini-refuges at night. We believe that use of mini-refuges by pintails could be increased if mini-refuges were (1) located in areas of traditionally high pintail use, (2) increased in size, (3) flooded immediately prior to hunting season, and (4) cleared of dense vegetation by rolling, disking, or burning.

Simulation of Anomalous Regional Climate Events with a Variable Resolution Stretched Grid GCM

NASA Technical Reports Server (NTRS)

Fox-Rabinovitz, Michael S.

1999-01-01

The stretched-grid approach provides an efficient down-scaling and consistent interactions between global and regional scales due to using one variable-resolution model for integrations. It is a workable alternative to the widely used nested-grid approach introduced over a decade ago as a pioneering step in regional climate modeling. A variable-resolution General Circulation Model (GCM) employing a stretched grid, with enhanced resolution over the US as the area of interest, is used for simulating two anomalous regional climate events, the US summer drought of 1988 and flood of 1993. The special mode of integration using a stretched-grid GCM and data assimilation system is developed that allows for imitating the nested-grid framework. The mode is useful for inter-comparison purposes and for underlining the differences between these two approaches. The 1988 and 1993 integrations are performed for the two month period starting from mid May. Regional resolutions used in most of the experiments is 60 km. The major goal and the result of the study is obtaining the efficient down-scaling over the area of interest. The monthly mean prognostic regional fields for the stretched-grid integrations are remarkably close to those of the verifying analyses. Simulated precipitation patterns are successfully verified against gauge precipitation observations. The impact of finer 40 km regional resolution is investigated for the 1993 integration and an example of recovering subregional precipitation is presented. The obtained results show that the global variable-resolution stretched-grid approach is a viable candidate for regional and subregional climate studies and applications.

In other centres dietary intake data were collected in 1993 only: Portugal: Coimbra (C/P); Poland: Marki (M/PL); Northern Ireland: Ballymoney-Limavady-Portstewart (BLP/NI/UK) and United States: Mansfield (Connecticut) (M/CT/USA). Using standardized methodologies, data were collected from a random stratified sample of elderly men and women born between 1913 and 1918. In 1993 dietary intake data were collected from 1125 subjects by a modified validated dietary history method. Over the 4-year study period, a decline in mean energy intake of one MJ or less per day was observed in most towns, which was significant (P < 0.01) in only four of the towns. The within- and between-centre variation of change was large. Overall, a slight decline was reported for all macronutrients and with the exception of protein, large within and between centre variations were observed in both men and women. Intake of energy and macronutrients was found to decline with age. This may be of special concern for small eaters.

The objective of this study was to assess the trends in hospitalization for sunburn in Western Australia from 1988 to 2008. De-identified linked hospital morbidity data for all index sunburn admissions in Western Australia for the period 1988 to 2008 were analyzed. Poisson regression analysis was used to estimate trends in hospital admissions. Hospitalizations increased from 1.6 (95% confidence interval [CI] = 1.0-2.2) per 100 000 person years in 1988 to 2.7 (95% CI = 1.9-3.4) per 100 000 person years in 1997, declining thereafter to 1.5 (95% CI = 1.0-2.0) per 100 000 person years in 2008. Increased hospitalizations rates were estimated for adults 25 to 44 years and 65 years or older, with a significant decline estimated for children younger than 5 years; rates remained stable for all other age groups. This study found no significant overall reduction in sunburn hospitalizations over the 20-year study period. raise concerns about the sun-protective behaviors and skin cancer risk of the population in Western Australia.

2007-11-01

Crown defoliation of oak (Quercus robur and Q. petraea) was analysed in 808 trees during three forest condition surveys (1988, 1993, and 1999) in the southern Sweden. From 1988 to 1999 crown defoliation increased by more than 20%. Changes in crown defoliation were related to the pH in the upper 20-30 cm of the mineral soils, which was closely connected to other measures of soil fertility (cation exchange capacity, CEC and C/N ratio). Trees growing on soils with a high pH (> or =4.00, in BaCl2 filtrate), high CEC and low C/N ratio had significantly lower crown defoliation than trees growing on more acid soils (pH <4.00), indicating that less favourable soil conditions may further enhance oak decline. Age did not differentiate trees with respect to crown defoliation, indicating that decline in crown condition was not due to an age-related increase in crown transparency. Considering only trees younger than 100 years, a significant interaction was observed between changes in crown defoliation and soil pH. Trees younger than 100 years old growing on more acidic soils had a greater increase in crown transparency than trees on more basic soils between 1988 and 1999. Trees > or =100 years old had significantly higher defoliation on more acidic than on more basic soils, however defoliation dynamics of these trees over 1988-99 was not related to soil acidity. Two biotic agents (insect and fungal leaf infections) evaluated in this study did not prove to be important drivers of defoliation dynamics.

Liver transplantation is now routine therapy for a variety of childhood liver diseases; however, there are no detailed reports of long-term results from a Canadian centre. We reviewed data from the first 16 years of a pediatric liver transplantation program to determine survival, complications and long-term outcomes. The outcomes to December 2000 for all children (age less than 18 years) who received a liver transplant at the London Health Sciences Centre between April 1984 and December 1999 were reviewed. The recipients were grouped according to the period in which they received the transplant (period 1, April 1984 to July 1988; period 2, August 1988 to December 1993; or period 3, January 1994 to December 1999). Data were obtained from medical charts; in-person interviews, questionnaires or telephone contact with patients and their families; contact with referring physicians; and school records. Outcome measures included patient survival, retransplantation, complications and long-term outcomes (specifically steroid withdrawal and growth and development). A total of 116 children (29 in period 1, 46 in period 2 and 41 in period 3) (median age 5.6 years at the time of the procedure) received a total of 140 liver grafts (32 in period 1, 57 in period 2 and 51 in period 3). Of the 116 patients, 23 (20%) were less than 1 year old at the time of transplantation. Biliary atresia was the most common indication for liver transplantation (57 [49%] of the 116 patients). The number of patients surviving to 1 year after transplantation was 20 (69%) of the 29 patients from period 1, 40 (87%) of the 46 patients from period 2 and 38 (93%) of the 41 patients from period 3. The percentage of patients receiving reduced size grafts from adult donors, including live donors, increased from 2/32 (6%) in period 1 to 22/51 (43%) in period 3. Retransplantation was required for 9 (31%) of the 29 patients from period 1, 6 (13%) of the 46 patients from period 2 and 7 (17%) of the 41 patients from period 3. Among these patients, 1-year survival was 33% (3/9) for period 1, 83% (5/6) for period 2 and 100% (7/7) for period 3. Eighteen of the 22 deaths occurred within 4 months after surgery. Only 3 (3%) of the 116 patients experienced post-transplant lymphoproliferative disease. Steroids were discontinued (usually within 2 years after surgery) for the following proportions of surviving transplant recipients: 17 (89%) of the 19 patients from period 1, 29 (78%) of the 37 patients from period 2 and 21 (55%) of the 38 patients from period 3. Most of the surviving patients had normal growth (82/94 or 87%) and development (73/94 or 78%), and these outcomes were consistent across the 3 periods of study. Survival and long-term outcomes continue to improve for most children who receive liver transplants. These improvements may be due to improved surgical technique, perioperative care and, to a lesser extent, immunosuppressive therapy.

The Effects of Vehicle Redesign on the Risk of Driver Death.

PubMed

Farmer, Charles M; Lund, Adrian K

2015-01-01

This study updates a 2006 report that estimated the historical effects of vehicle design changes on driver fatality rates in the United States, separate from the effects of environmental and driver behavior changes during the same period. In addition to extending the period covered by 8 years, this study estimated the effect of design changes by model year and vehicle type. Driver death rates for consecutive model years of vehicle models without design changes were used to estimate the vehicle aging effect and the death rates that would have been expected if the entire fleet had remained unchanged from the 1985 calendar year. These calendar year estimates are taken to be the combined effect of road environment and motorist behavioral changes, with the difference between them and the actual calendar year driver fatality rates reflecting the effect of changes in vehicle design and distribution of vehicle types. The effects of vehicle design changes by model year were estimated for cars, SUVs, and pickups by computing driver death rates for model years 1984-2009 during each of their first 3 full calendar years of exposure and comparing with the expected rates if there had been no design changes. As reported in the 2006 study, had there been no changes in the vehicle fleet, driver death risk would have declined during calendar years 1985-1993 and then slowly increased from 1993 to 2004. The updated results indicate that the gradual increase would have continued through 2006, after which driver fatality rates again would have declined through 2012. Overall, it is estimated that there were 7,700 fewer driver deaths in 2012 than there would have been had vehicle designs not changed. Cars were the first vehicle type whose design safety generally exceeded that of the 1984 model year (starting in model year 1996), followed by SUVs (1998 models) and pickups (2002 models). By the 2009 model year, car driver fatality risk had declined 51% from its high in 1994, pickup driver fatality risk had declined 61% from its high in 1988, and SUV risk had declined 79% from its high in 1988. The risk of driver death in 2009 model passenger vehicles was 8% lower than that in 2008 models and about half that in 1984 models. Changes in vehicles, whether from government regulations and consumer testing that led to advanced safety designs or from other factors such as consumer demand for different sizes and types of vehicles, have been key contributors to the decline in U.S. motor vehicle occupant crash death rates since the mid-1990s. Since the early 1990s, environmental and behavioral risk factors have not shown similar improvement, until the recession of 2007, even though there are many empirically proven countermeasures that have been inadequately applied.

Procedures such as liver transplantation, which entail large costs while benefiting only a small percentage of the population, are being increasingly scrutinized by third-party payors. The purpose of our study was to conduct a longitudinal analysis of the early clinical outcomes and health care resource utilization for liver transplantation in the United States. The Nationwide Inpatient Sample database was used to conduct a longitudinal analysis of the clinical outcome and resource utilization data for liver transplantation procedures in adult recipients performed in the United States over three time periods (Period I: 1988-1993; Period II: 1994-1998: Period III: 1999-2003). Compared to Period I, adult liver transplant recipients were more likely to be male, older, and non-White in Period III. Recipients were more likely to have at least one major comorbidity preoperatively than in Period I. The in-hospital mortality rate after liver transplantation decreased significantly from Period I to Period III, but the major intraoperative and postoperative complication rates increased over the same time period. Mean length of hospital stay decreased over the 15-year period, but the percentage of patients with a non-routine discharge status increased. Our findings indicate that the rate of postoperative complications and non-routine discharges after liver transplantation is increasing. However, these negative changes in the cost-outcomes relationship for liver transplantation are balanced by improving postoperative survival rates and reductions in the length of hospital stay.

A winter bird survey was conducted throughout Maryland, primarily by volunteers, during the 6 winters of 1988 to 1993 between the dates of 10 Jan and 10 Feb. The state of Maryland is covered by 1231 blocks (9.5 sq. miles each), each comprising one-sixth of the standard U.S.G.S. 7.5 minute topographic quadrangle, and 548 of these blocks (44.5%) were surveyed for winter birds. Blocks were chosen in a systematic pattern with eventually almost every other block in the state having been surveyed as of Feb, 1993. Volunteers conducted each 4-hour survey by walking a 4-6 mile route chosen by the volunteer to sample habitats in proportion to their availability in the block. Surveys began around sunrise (~7:30 a.m.) and all birds seen or heard during the 4 hours were recorded on data sheets. The data were then used to create maps representing the distribution and relative abundance of each species of wintering bird found in at least 10 blocks in the state.

Five X-ray observations of the intermediate polar FO Aqr spanning ten years

The comparison of five X-ray observations of FO Aqr reveals that the morphology of the X-ray light curve changes considerably with time. Power spectra from 1988 and 1993 reveal a sideband component, while power spectra from 1990 do not. This suggests that the amount of disk overflow accretion varies as a function of time. From structured spin folded light curves, the presence of complex, multicomponent emitting regions near the white dwarf's surface can be inferred.

Supernova (SN) 2005ip was a Type IIn event notable for its sustained strong interaction with circumstellar material (CSM), coronal emission lines and infrared (IR) excess, interpreted as shock interaction with the very dense and clumpy wind of an extreme red supergiant. We present a series of late-time spectra of SN 2005ip and a first radio detection of this SN, plus late-time X-rays, all of which indicate that its CSM interaction is still strong a decade post-explosion. We also present and discuss new spectra of geriatric SNe with continued CSM interaction: SN 1988Z, SN 1993J and SN 1998S. From 3 to 10 yr post-explosion, SN 2005ip's Hα luminosity and other observed characteristics were nearly identical to those of the radio-luminous SN 1988Z, and much more luminous than SNe 1993J and 1998S. At 10 yr after explosion, SN 2005ip showed a drop in Hα luminosity, followed by a quick resurgence over several months. We interpret this Hα variability as ejecta crashing into a dense shell located ≲ 0.05 pc from the star, which may be the same shell that caused the IR echo at earlier epochs. The extreme Hα luminosities in SN 2005ip and SN 1988Z are still dominated by the forward shock at 10 yr post-explosion, whereas SN 1993J and SN 1998S are dominated by the reverse shock at a similar age. Continuous strong CSM interaction in SNe 2005ip and 1988Z is indicative of enhanced mass-loss for ˜103 yr before core collapse, longer than Ne, O or Si burning phases. Instead, the episodic mass-loss must extend back through C burning and perhaps even part of He burning.

A 3-D model analysis of the slowdown and interannual variability in the methane growth rate from 1988 to 1997

Methane has exhibited significant interannual variability with a slowdown in its growth rate beginning in the 1980s. We use a 3-D chemical transport model accounting for interannually varying emissions, transport, and sinks to analyze trends in CH4 from 1988 to 1997. Variations in CH4 sources were based on meteorological and country-level socioeconomic data. An inverse method was used to optimize the strengths of sources and sinks for a base year, 1994. We present a best-guess budget along with sensitivity tests. The analysis suggests that the sum of emissions from animals, fossil fuels, landfills, and wastewater estimated using Intergovernmental Panel on Climate Change default methodology is too high. Recent bottom-up estimates of the source from rice paddies appear to be too low. Previous top-down estimates of emissions from wetlands may be a factor of 2 higher than bottom-up estimates because of possible overestimates of OH. The model captures the general decrease in the CH4 growth rate observed from 1988 to 1997 and the anomalously low growth rates during 1992-1993. The slowdown in the growth rate is attributed to a combination of slower growth of sources and increases in OH. The economic downturn in the former Soviet Union and Eastern Europe made a significant contribution to the decrease in the growth rate of emissions. The 1992-1993 anomaly can be explained by fluctuations in wetland emissions and OH after the eruption of Mount Pinatubo. The results suggest that the recent slowdown of CH4 may be temporary.

Patterns of variation in clutch sizes in a guild of temperate-nesting dabbling ducks

Clutch sizes of temperate-nesting dabbling ducks vary widely within and between years. Biologists have long been interested in why such patterns exist but have had difficulty separating intrinsic effects from environmental influences. In an attempt to gain greater insight into the roles of intrinsic and environmental influences on clutch sizes of dabbling ducks, we compared clutch-size patterns of mallard, northern pintail, gadwall, northern shoveler, and blue-winged teal in North Dakota and South Dakota over a 3-year period. The study was conducted during 1993-1995 when wetland habitat conditions were exceptionally consistent within time intervals but varied widely from the onset to the end of the study. We found that clutch sizes of gadwall and blue-winged teal were significantly smaller at the onset of nesting in 1993, when water conditions remained relatively poor following a 5-year drought (1988-1992), and pintail clutch sizes were larger late in the breeding season in 1993 after wetland conditions became exceptionally productive following heavy rains in late May and June. These findings were associated with gadwall and teal relying primarily on nutrients acquired on the breeding grounds to produce early clutches, and pintails using an exceptionally high proportion of their body lipids to produce early clutches, making this species highly dependent on abundant local sources of lipids for clutches produced later. Mallard, pintail, and shoveler rely largely on endogenous lipids carried to the breeding grounds to produce early clutches, and at least in the years of study, clutch sizes exhibited minimal variation at the onset of nesting. Our findings, when examined in context with existing information, suggest that interspecific variation in clutch sizes results from innate differences in several traits -- including body size, diet, timing of lipid acquisition, and nesting-- that affect the amount of lipid available for egg production. Annual differences in clutch sizes of all five species were not significant when effects of annual variation in nest initiation dates was accounted for, reflecting the key role of environmental influences on intraspecific variation among years.

Prevalence of Rentbacterium salmoninarum in juvenile spring chinook salmon at Columbia and Snake river hatcheries, 1993-1996

We monitored the prevalence and severity of Renibacterium salmoninarum (RS) infections in juvenile hatchery spring chinook salmon Oncorhynchus tshawytscha at eight Columbia and Snake river hatcheries from 1993 through 1996. This study followed a prior study that monitored RS in the same hatcheries from 1988 through 1992. In the current study, we found that the prevalence of RS-positive fish declined at two hatcheries relative to the preceding 5 years. Prevalence dropped from near 90% in 1992 to below 50% at both sites by 1993 and was less than 20% at three locations in 1995. In contrast, prevalence increased at four of seven sites in 1993 and six of seven sites in 1994. This indicated that previously reported declines in RS prevalence at these locations might have been temporary. Our results showed that in 1993 the majority of fish at all monitored hatcheries had low RS-antigen levels and remained that way at most locations through 1996. These results suggest that certain hatchery practices may limit the severity of RS infections. Although elevations at two sites in 1994 and 1995 indicate reductions in RS were temporary in the short term, long-term monitoring will undoubtedly be required given the many factors that influence disease processes.

Content analysis of television advertising for cars and minivans: 1983-1998.

2003-11-01

Very little systematic information is available about the predominant advertising themes automobile manufacturers have depicted over the years. The goal of the present study was to analyze television vehicle advertising to understand how cars and passenger vans are being portrayed in the media and how this has changed over time. A virtually complete sample (561) of car and passenger van advertisements from 1998, and a sample of advertisements from 1983 (98), 1988 (96), and 1993 (95), was analyzed for content. Performance, most often exemplified as speed, power, and maneuverability, was the primary theme in 17% of advertisements in 1998 and was depicted in half of all advertisements. Performance was also the most frequent theme over time. Sales incentives also was a popular theme in each year studied, and was predominant in 1993. Safety was mentioned infrequently, except in 1993; a time when manufacturers were competing to install airbags in their vehicles. A focus on vehicle performance in advertising that does not depict the potential negative consequences can have the deleterious effects of glamorizing and legitimizing high-speed travel. Furthermore, manufacturers are missing an opportunity to promote vehicle safety, a feature that consumers have indicated is very important to them.

Sharing the blame: smoking experimentation and future smoking-attributable mortality due to Joe Camel and Marlboro advertising and promotions.

Despite public denials, internal tobacco company documents indicate that adolescents have long been the target of cigarette advertising and promotional activities. Recent longitudinal evidence suggests that 34% of new experimentation occurs because of advertising and promotions. To apportion responsibility for smoking experimentation and future smoking-attributable mortality among major cigarette brands attractive to young people (Camel and Marlboro). DATA SOURCES, SETTING, AND PARTICIPANTS: Data were from confirmed never-smoking adolescents (12-17 years old) responding to the 1993 (n = 2659) and 1996 (n = 2779) population-based California Tobacco Surveys. Adolescents named the brand of their favourite cigarette advertisements and tobacco promotional items. Using these "market shares" and the relative importance of advertising and promotions in encouraging smoking, we estimated how many new experimenters from 1988 to 1998 in the United States can be attributed to Camel and Marlboro. From other data on the natural history of smoking, we projected how many future deaths in the United States can be attributed to each brand. Although Camel advertisements were favoured more than Marlboro and other brands in 1993 and 1996, the "market share" for promotional items shifted markedly during this period from Camel and other brands towards Marlboro. We estimated that between 1988 and 1998, there will be 7.9 million new experimenters because of tobacco advertising and promotions. This will result in 4.7 million new established smokers: 2.1, 1.2, and 1.4 million due to Camel, Marlboro, and other brands' advertising and promotions, respectively. Of these, 1.2 million will eventually die from smoking-attributable diseases: 520,000 from Camel, 300,000 from Marlboro, and the remainder from other brands. Our analysis provides a reasonable first estimate at sharing the blame for the long-term health consequences of smoking among the major brands that encourage adolescents to start smoking.

Understanding the causes of under-five deaths is key to realizing sustainable developmental goals. The aim of this descriptive study was to investigate the causes of under-five mortality in İstanbul during 2011 and compare the findings to those of 1988 and 2000. All burial records of İstanbul were evaluated, and cemetery records of 1494 children, who died at under five years of age and were buried in İstanbul Metropolitan Municipality Cemeteries between 1 January and 31 December 2011, were analyzed. Several sociodemographic characteristics and causes of death were compared with the results of studies carried out in 1988 and 2000 in İstanbul with similar methods. Under-five mortality rate was lower in 2011 than in 1988 and 2000. Of all deaths, 58.8% had occurred in the neonatal period and most were in the first day of life, similarly to those of 1988 and 2000. The proportion of deaths in the age group of 1-4 years was found to be increasing. Prematurity and perinatal causes remained the main cause of death under five years of age in İstanbul during the 23-year period. Unknown causes, due to misclassification, were still seen in a relatively high proportion. Under-five mortality rate and death due to infectious diseases decreased in İstanbul from 1988 to 2011. Our findings showed a need for more emphasis on perinatal events and better evaluation of causes of death in clinical practice.

Malaysia consists of two major parts, a mainland on the Peninsular Malaysia and the East Malaysia on the Borneo Island. Their surrounding waters connect the Andaman Sea located northeast of the Indian Ocean to the Celebes Sea in the western tropical Pacific Ocean through the southern East Sea of Vietnam/South China Sea. As a result, inter-annual sea level in the Malaysian waters is governed by various regional phenomena associated with the adjacent parts of the Indian and Pacific Oceans. We estimated sea level rise (SLR) rate in the domain using tide gauge records often being gappy. To reconstruct the missing data, two methods are used: (i) correlating sea level with climate indices El Niño-Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD), and (ii) filling the gap using records of neighboring tide gauges. Latest vertical land movements have been acquired to derive geocentric SLR rates. Around the Peninsular Malaysia, geocentric SLR rates in waters of Malacca Strait and eastern Peninsular Malaysia during 1986-2011 are found to be 3.9±3.3 mm/year and 4.2 ± 2.5 mm/year, respectively; while in the East Malaysia waters the rate during 1988-2011 is 6.3 ± 4.0 mm/year. These rates are arguably higher than global tendency for the same periods. For the overlapping period 1993-2011, the rates are consistent with those obtained using satellite altimetry.

Between 1993 and 1996 in Taipei, Taiwan, we studied the prevalences of HIV-1, HTLV-I, HSV-2, Chlamydia trachomatis, and syphilis infection in female commercial sex workers (CSW) and the pathogens' associated risk factors. Female CSW from nine massage parlors, two karaoke bars (KB), and 22 brothels in Taipei city participated in this study. Two of 557 (0.4%) KB CSWs from those who participated during the period from 1993 to 1994 had HIV-1 infection, whereas no KB CSWs in the periods 1994 to 1995 or 1995 to 1996 had HIV-1 infection. None of the 725 MP CSWs or 291 brothel CSWs who participated in the study between 1993 and 1996 had HIV-1 infection. In contrast, CSWs from brothels had elevated rates of both HTLV-I and active chlamydia infections compared with KB and MP CSWs (p < .05 and p < .005, respectively). KB CSWs showed an elevated rate of HSV-2 infection in the years 1993 and 1994 when compared with CSWs employed by brothels and MPs (p < .005). The prevalence rates of syphilis for CSWs from brothels dropped from 42.8% in the year 1993 to 1994 to 26.3% in the 1995 to 1996 period, whereas for KB and MP CSWs, the rates were < 6% in each of year studied.

Do counsellors in general practice surgeries and clinical psychologists in the National Health Service see the same patients?

An audit was conducted of a counsellor's work over the period 1989-1993 at two general practice surgeries in Coventry. Comparative data were available for general practitioner (GP)-referred patients seen in the district clinical psychology department in Coventry during 1988-1992. The counsellor saw significantly more patients referred with anxiety, depression, marital problems, child management and physical illness than did psychologists, whilst psychologists saw significantly more patients with relationship problems and personality disorders. To the question, 'Are these services effective?' the answer is yes, both services are effective, but they are treating different patient populations. PMID:7769604

We have considered trends in the incidence of Kaposi sarcoma (KS) between 1978 and 2002, using data from the Swiss Cancer Registries of Vaud and Neuchâtel (786000 inhabitants). Overall, 163 cases were registered, 149 in men and 14 in women. After a peak reached in 1988-1992 in both men (2.71/100000, world-standard) and women (0.26/100000), a considerable decline was observed thereafter, to reach 0.80/100000 men and 0.06/100000 women in 1998-2002. In men, there was a substantial decline (from 4.91/100000 in 1988-1992 to 0.56 in 1998-2002) at age 15-44 years, a fall from 2.91 in 1993-1997 to 2.37 in 1998-2002 at age 45-64 years, but some increases over the last decade in the elderly, likely due to cases of classic KS. The declines in KS confirm that earlier anti-retroviral therapies (HAART) had already reduced the risk of KS, and the newest highly active anti-retroviral therapies have further contributed to the decline of KS in recent years.

Purpose: To examine the role of brachytherapy in the treatment of cholangiocarcinomas in a relatively large group of patients. Methods and Materials: Using the Surveillance, Epidemiology and End Results database, a total of 193 patients with cholangiocarcinoma treated with brachytherapy were identified for the period 1988-2003. The primary analysis compared patients treated with brachytherapy (with or without external-beam radiation) with those who did not receive radiation. To try to account for confounding variables, propensity score and sensitivity analyses were used. Results: There was a significant difference between patients who received radiation (n = 193) and those who did not (nmore » = 6859) with regard to surgery (p < 0.0001), race (p < 0.0001), stage (p < 0.0001), and year of diagnosis (p <0.0001). Median survival for patients treated with brachytherapy was 11 months (95% confidence interval [CI] 9-13 months), compared with 4 months for patients who received no radiation (p < 0.0001). On multivariable analysis (hazard ratio [95% CI]) brachytherapy (0.79 [0.66-0.95]), surgery (0.50 [0.46-0.53]), year of diagnosis (1998-2003: 0.66 [0.60-0.73]; 1993-1997: (0.96 [0.89-1.03; NS], baseline 1988-1992), and extrahepatic disease (0.84 [0.79-0.89]) were associated with better overall survival. Conclusions: To the authors' knowledge, this is the largest dataset reported for the treatment of cholangiocarcinomas with brachytherapy. The results of this retrospective analysis suggest that brachytherapy may improve overall survival. However, because of the limitations of the Surveillance, Epidemiology and End Results database, these results should be interpreted cautiously, and future prospective studies are needed.« less

Felippa, Carlos A.; Farhat, Charbel; Park, K. C.; Militello, Carmelo; Schuler, James J.

1993-01-01

This research program has dealt with the theoretical development and computer implementation of reliable and efficient methods for the analysis of coupled mechanical problems that involve the interaction of mechanical, thermal, phase-change and electromagnetic subproblems. The focus application has been the modeling of superconductivity and associated quantum-state phase-change phenomena. In support of this objective the work has addressed the following issues: (1) development of variational principles for finite elements; (2) finite element modeling of the electromagnetic problem; (3) coupling of thermal and mechanical effects; and (4) computer implementation and solution of the superconductivity transition problem. The research was carried out over the period September 1988 through March 1993. The main accomplishments have been: (1) the development of the theory of parametrized and gauged variational principles; (2) the application of those principled to the construction of electromagnetic, thermal and mechanical finite elements; and (3) the coupling of electromagnetic finite elements with thermal and superconducting effects; and (4) the first detailed finite element simulations of bulk superconductors, in particular the Meissner effect and the nature of the normal conducting boundary layer. The grant has fully supported the thesis work of one doctoral student (James Schuler, who started on January 1989 and completed on January 1993), and partly supported another thesis (Carmelo Militello, who started graduate work on January 1988 completing on August 1991). Twenty-three publications have acknowledged full or part support from this grant, with 16 having appeared in archival journals and 3 in edited books or proceedings.

Response of a hydrothermal system to magmatic heat inferred from temporal variations in the complex frequencies of long-period events at Kusatsu-Shirane Volcano, Japan

USGS Publications Warehouse

Nakano, M.; Kumagai, H.

2005-01-01

We investigate temporal variations in the complex frequencies (frequency and quality factor Q) of long-period (LP) events that occurred at Kusatsu-Shirane Volcano, central Japan. We analyze LP waveforms observed at this volcano in the period between 1988 and 1995, which covers a seismically active period between 1989 and 1993. Systematic temporal variations in the complex frequencies are observed in October-November 1989, July-October 1991, and September 1992-January 1993. We use acoustic properties of a crack filled with hydrothermal fluids to interpret the observed temporal variations in the complex frequencies. The temporal variations in October-November 1989 can be divided into two periods, which are explained by a gradual decrease and increase of a gas-volume fraction in a water-steam mixture in a crack, respectively. The temporal variations in July-October 1991 can be also divided into two periods. These variations in the first and second periods are similar to those observed in November 1989 and in September-November 1992, respectively, and are interpreted as drying of a water-steam mixture and misty gas in a crack, respectively. The repeated nature of the temporal variations observed in similar seasons between July and November suggests the existence of seasonality in the occurrence of LP events. This may be caused by a seasonally variable meteoritic water supply to a hydrothermal system, which may have been heated by the flux of volcanic gases from magma beneath this volcano. ?? 2005 Elsevier B.V.

First, to quantify trends in the contribution of alcohol-related mortality to mortality disparity in Finland by income quintiles. Secondly, to estimate the degree to which education, social class and economic activity explain the income-mortality association in alcohol-related and other mortality in four periods within 1988-2012. Register-based longitudinal study using an 11% random sample of Finnish residents linked to socio-economic and mortality data in 1988-2012 augmented with an 80% sample of all deaths during 1988-2007. Mortality rates and discrete time survival regression models were used to assess the income-mortality association following adjustment for covariates in 6-year periods after baseline years of 1988, 1994, 2001, and 2007. Finland. Individuals aged 35-64 years at baselines. For the four study periods for men/women, the final data set comprised, respectively, 26,360/12,825, 22,561/11,423, 20,342/11,319 and 2651/1514 deaths attributable to other causes and 7517/1217, 8199/1450, 9807/2116, 1431/318 deaths attributable to alcohol-related causes. Alcohol-related deaths were analysed with household income, education, social class and economic activity as covariates. The income disparity in mortality originated increasingly from alcohol-related causes of death, in the lowest quintile the contribution increasing from 28 to 49% among men and from 11 to 28% among women between periods 1988-93 and 2007-12. Among men, socio-economic characteristics attenuated the excess mortality during each study period in the lowest income quintile by 51-62% in alcohol-related and other causes. Among women, in the lowest quintile the attenuation was 47-76% in other causes, but there was a decreasing tendency in the proportion explained by the covariates in alcohol-related mortality. The income disparity in mortality among working-age Finns originates increasingly from alcohol-related causes of death. Roughly half the excess mortality in the lowest income quintile during 2007-12 is explained by the covariates of household income, education, social class and economic activity. © 2015 Society for the Study of Addiction.

Wilson, Colleen A.; Finger, Mark H.; Scott, D. Matthew

1997-01-01

Cep X-4 was discovered with the Orbiting Solar Observatory (OSO) 7 Satellite in 1973 June-July, but no pulsations were detected. In March 1988, an additional outburst was observed with Gingaq. Pulsations at a period of 66.2490 +/- .0001 s were detected during a month long outburst which peaked at about 100 mCrab (1-20 keV) in early April 1988. The source apparently did not appear again until June 1993 when it was detected by Roentgen Satellite (ROSAT) and Burst and Transient Source Experiment (BATSE). Pulsations at a period of 66.2499 +/- .0007 s were detected by BATSE. The outburst lasted about two weeks and had a peak pulsed flux of 15-20 mCrab (20-50 keV). In July 1997, BATSE and the All-Sky Monitor (ASM) on Rossi X-ray Timing Explorer (RXTE) observed a new outburst from Cep X-4. Pulsations at a period of 66.2743 +/- 0.0005 s were detected by BATSE. This outburst lasted about 2 weeks and peaked at a pulsed flux of about 10-15 mCrab (20-50 keV). Results of a search of BATSE data for additional outbursts will be presented. Pulse frequency and flux histories will be presented and compared to the flux history from the RXTE ASM. Implications of the apparent spin-down between outbursts will be discussed.

Introduction: Lung cancer (LC) has been one of the most commonly diagnosed cancers worldwide, both in terms of new cases and mortality. Exponential growth of economic and industrial activities in recent decades in the Delhi urban area may have increased the incidence of LC. The primary objective of this study was to evaluate the time trend according to gender. Method: LC incidence data over 25 years were obtained from the population based urban Delhi cancer registry. Joinpoint regression analysis was applied for evaluating the time trend of age-standardized incidence rates. The age-period-cohort (APC) model was employed using Poisson distribution with a log link function and the intrinsic estimator method. Results: During the 25 years, 13,489 male and 3,259 female LC cases were registered, accounting for 9.78% of male and 2.53% of female total cancer cases. Joinpoint regression analysis revealed that LC incidence in males continued to increase during the entire period, a sharp acceleration being observed starting from 2009. In females the LC incidence rate remained a plateau during 1988-2002 and thereafter increased. The cumulative risks for 1988-2012 were 1.79% and 0.45%. The full APC (IE) model showed best fit for an age-period-cohort effect on LC incidence, with significant increase with age peaking at 70-74 years in males and 65-69 years in females. A rising period effect was observed after adjusting for age and cohort effects in both genders and a declining cohort effect was identified after controlling for age and period effects. Conclusion: The incidence of LC in urban Delhi showed increasing trend from 1988-2012. Known factors such as environmental conservation, tobacco control, physical activity awareness and medical security should be implemented more vigorously over the long term in our population.

Bacterial meningitis is a severe and feared disease. We have studied bacterial meningitis in children in Sør-Trøndelag county during a 20-year period from 1988 to 2008. Medical records of children (in-patients) with spinal fluid findings or a clinical diagnosis of bacterial meningitis, at St. Olavs Hospital, were retrospectively reviewed. 112 cases of bacterial meningitis were registered in children below 16 years of age in Sør-Trøndelag county between 1988 and 2008. Children younger than 2 years had the highest occurrence, with a mean annual incidence of 42.3 per 100,000, whereas the incidence among children in the age group 2 to 16 was 5.7 per 100,000. We observed a decline in the occurrence from 19.1 per 100,000 in the period 1988 - 1991, to 6.9 per 100,000 in the period 2003 - 2006. 31 cases of Haemophilus influenzae type B, 26 cases of Neisseria meningitidis group B, 26 of Streptococcus pneumoniae and 19 cases with other pathogens were registered. The occurrence of H influenzae and N meningitidis have declined over the entire period, whereas S pneumoniae has increased. 6/112 children died (5.4 %) and 34 developed sequelae (30.4 %). In a multiple logistic regression analysis, the maximal value of C-reactive protein was associated with an increased risk of developing sequelae, adjusted for age and triggering microbe. The incidence of bacterial meningitis among children in Sør-Trøndelag has decreased significantly over the last 20 years, and meningitis is now a rare disease. Bacterial meningitis is most common among children below the age of two, and is still associated with a substantial mortality and risk of long-term neurological sequalae.

Water, bed sediment, and biota were sampled in streams from Butte to below Missoula as part of a program to characterize aquatic resources in the upper Clark Fork basin of western Montana. Water-quality data were obtained periodically at 16 stations during October 1992 through September 1993 (water year 1993); daily suspended-sediment data were obtained at six of these stations. Bed-sediment and biological data were obtained at 11 stations in August 1993. Sampling stations were located on the Clark Fork and major tributaries. The primary constituents analyzed were trace elements associated with mine tailings from historic mining and smelting activities. Water-quality data include concentra- tions of major ions, trace elements, and suspended sediment in samples collected periodically during water year 1993. A statistical summary of water- quality data is provided for the period of record at each station since 1985. Daily values of streamflow, suspended-sediment concentration, and suspended-sediment discharge are given for six stations. Bed-sediment data include trace- element concentrations in the fine and bulk fractions. Biological data include trace-element concentrations in whole-body tissue of aquatic benthic insects. Quality-assurance data are reported for analytical results of water, bed sediment, and biota.

Background There are an increasing number of reports on time trends in child and adolescent psychological problems but none from low- and middle-income countries, and very few covering the preschool period. The aim was to investigate changes in preschool behavioral/emotional problems in two birth cohorts from a middle-income country born 11 years apart. Methods We analyzed data from the 1993 and 2004 Pelotas birth cohort studies from Brazil. A subsample of 4-year olds from the 1993 cohort (634) and all 4-year olds from the 2004 cohort (3750) were assessed for behavioral/emotional problems through maternal report using the Child Behavior Checklist (CBCL). Response rates in these two population-based cohorts were above 90%. Results We found a significant increase in CBCL total problems, internalizing and externalizing mean scores over the 11-year period. For 1993 and 2004 Pelotas cohorts, respectively, CBCL mean values (SE) total problems scores were 27.9 (0.8) and 34.7 (0.3); for internalizing scores, 5.7 (0.2) and 6.3 (0.1) and for externalizing scores, 12.4 (0.4) and 15.5 (0.1). After adjusting for confounding variables, the largest increase from 1993 to 2004 was identified in the aggressive behavior syndrome score (Cohen's d = .50), followed by the externalizing problem score (Cohen's d = .40) and CBCL total problem score (Cohen's d = .36), respectively. The rise in child psychological problems was more marked in children from families with fewer assets and with less educated mothers. Conclusions Our findings provide evidence for a substantial increase in preschool behavioral problems among children in Brazil over an 11-year period. PMID:24735354

Background/Objective: The objective of the study was to provide current estimates of the prevalence and trends of overweight and obesity (OW+OB) in Mexican children and adolescents. Subjects/Methods: Body mass index objectively measured was analyzed for 37 147 children and adolescents aged 0–19 years obtained in 2012 as part of the National Health and Nutrition Survey (ENSANUT-2012), a nationally representative sample of the Mexican population. In addition, data from previous National Nutrition Surveys obtained in 1988, 1999 and 2006 were compared with analyze trends over a 24-year period (1988–2012) for children <5 years of age and adolescents and over a 13-year period (1999–2012) for school-age children. World Health Organization Child Growth Standard was used to define OW+OB. Results: In 2012, 33.5% of children <5 years of age (both sexes) were at risk of overweight or were overweight (OW); 32% and 36.9% of girls and boys 5–11 years of age were OW+OB, respectively, and 35.8% and 34.1% of female and male adolescents were OW+OB, respectively. Statistically significant trends were documented for all age groups during the study period. Overall change in the combined prevalence in preschool children was 6.3±1.0 percentage points (pp; P<0.001; 0.26 pp per year) in the last 24 years, showing the highest increase between 1988 and 1999, whereas for school-age girls (from 1999 to 2012) and adolescent females (from 1988 to 2012), OW+OB increased across all periods at a declining trend, with an overall change of 0.5 and 1.0 pp per year, respectively. Changes in the prevalence of OW+OB were highest among children and adolescents in the lowest quintile of the household living condition index. Conclusions: Prevalence of OW+OB among children and adolescents increased significantly during the last 13–24 years. The rate of increase has declined in the last 6 years in all age groups. Changes in prevalence of OW+OB presented here suggest that, in Mexico, the burden of obesity is shifting toward the groups with lower socioeconomic level. PMID:28287630

Neisseria meningitidis is an important cause of meningitis, bacteremia and septic shock syndrome. We herein present the distribution of serogroups, serotypes and serosubtypes of 2244 isolates of N. meningitidis from patients with meningitis or meningococcemia, received within the period 1993-2005, in the National Reference Laboratory, INEI-ANLIS "Dr. Carlos G. Malbrán", from 33 Argentine hospitals that are included in a National Network devoted to for the study of bacterial meningitis. Between 1993-1995, serogroup B was prevalent (66%) whereas in the period from 1995-2001, serogroup C prevailed (65%). However, following but after that period, the prevalence of serogroup B was recovered. In the last 5 years of the studied period, the serogroups Y and W135 represented as a whole a 15.6% as a whole whereas up to the year 2000 during the first 6 years they accounted for it was of 4.7%. Higher diversity in the distribution of serotypes and serosubtypes was observed within serogroup B. The nonsubtypable isolates throughout the period of study represented the 52.8%, this high percentage demonstrates the limited capacity of the serotyping for the determination of meningococcal/meningococcus subtypes. of meningococco.

The Tuscany Mesothelioma Register (ARTMM) records pleural malignant mesothelioma cases of Tuscany residents, diagnosed by histological, cytological, or clinical (radiography or computerized tomography) examinations. The ARTMM began in 1988 and estimates mesothelioma incidence in Tuscany and collects information on past asbestos exposure of mesothelioma cases. The aim of this paper was to describe the incidence of pleural mesothelioma cases in Tuscany and to analyse their possible past asbestos exposures. We considered pleural mesothelioma cases recorded in ARTMM in the period 1988-2000 and interviews collected for these cases. In order to identify past asbestos exposure in the occupational and non-occupational history of patients, interviews were carried out using a standardised questionnaire. In the period 1988-2000, 494 pleural malignant mesothelioma cases were recorded in the ARTMM; 82% were males. In the periods 1988-1993, 1994-1997, 1998-2000 the incidence rates, standardised on the Italian population (per 100,000), were respectively 1.15, 1.57, 2.58 among males; 0.29; 0.27; 0.29 among females. Information on occupational history was collected for 418 mesothelioma patients (85% of recorded cases): 173 mesothelioma cases were directly interviewed; for 245 cases relatives or work colleagues were interviewed. Occupational asbestos exposure was ranked as certain, probable or possible in 72% of the interviewed cases (80% of males; 20% of females). Environmental and non-occupational asbestos exposure was identified in 1% of males, and 3% of females. In 24% of the interviewed cases (15% of males; 74% of females) no known asbestos exposure was identified. Occupational asbestos exposure occurred in maritime activities (shipyards, dock work, merchant and regular Navy), the building industry, railway carriage construction and maintenance, rail transport, textile industries (mainly rag sorting), electricity production, asbestos cement manufacture, chemical, iron and steel industries and in glass manufacturing. In Tuscany two areas are distinguished for their well-documented and massive use of asbestos: the coastal areas (Livorno and Massa Carrara) for maritime activities, and the areas of Pistoia and Arezzo for railway carriage construction and repair. Mesothelioma incidence rates in these areas are the highest in the whole region. Further investigation is needed in order to identify unknown asbestos uses and consequent exposure, in particular for females. Uncertainty as regards occurrence of asbestos exposure persists in the textile industries where the mesothelioma epidemics have not yet declined. Research hypotheses are addressed on the re-use of jute bags previously containing asbestos, therefore collection of further information on periods and methods of this recycling activity is essential.

A survey protocol for the Southwestern Willow Flycatcher (Empidonax traillii extimus)

The southwestern willow flycatcher (Empidonax traillii extimus) is a riparian obligate neotropical migrant, nesting in cottonwood-willow associations and structurally similar riparian vegetation associations. The southwestern willow flycatcher has declined through the twentieth century, primarily due to a number of factors, including loss and fragmentation of riparian habitat, brood parasitism by brown-headed cowbirds (Molothrus ater), invasion of riparian habitat by the exotic tamarisk (Tamarix sp.), and predation (Hunter et al. 1987), Unitt 1987, Hunter et al. 1988, Whitfield 1990, Harris 1991, Rosenberg et al. 1991). In 1991 the U.S. Fish and Wildlife Service (USFWS) designated the southwestern willow flycatcher as a candidate category 1 species (USFWS 1991), indicating that the USFWS had sufficient information to support listing under the Endangered Species Act of 1973, as amended (Act), but that a proposal to list was precluded by other listing actions of higher priority. In July 1993, the USFWS proposed to list E. t. extimus as an endangered species and to designate critical habitat under the Act (USFWS 1993). The states of Arizona, New Mexico, and California comprise most of the southwestern willow flycatcher's historic and current range. Each of these states lists the species as endangered [Arizona Game and Fish Department (AGFD) 1988, New Mexico Department of Game and Fish (NMDGF) 1988, California Department of Game and Fish 1991]. Because of the precarious status of the southwestern willow flycatcher (Unitt 1987, USFWS 1993), there is a need to identify as many remaining breeding locations as possible. This survey protocol was developed to facilitate and standardize breeding surveys, and is based primarily on extensive 1992 and 1993 field surveys. It was developed at the request of the Arizona Partners in flight, and organization of Federal and State agencies, nongovernmental organizations, and individuals. This protocol is intended to be useful throughout the range of the southwestern willow flycatcher. The authors welcome any suggestions on refining this protocol.

Factors influencing rising caesarean section rates in China between 1988 and 2008.

To identify factors driving the rapid increase in caesarean section in China between 1988 and 2008. Data from four national cross-sectional surveys (1993, 1998, 2003 and 2008) and modified Poisson regression were used to determine whether changes in household income, access to health insurance or women's education accounted for the rise in caesarean sections in urban and rural areas. In 2008, 64.1% of urban women and 11.3% of women in the poorest rural region reported giving birth by caesarean section. A fast rise was occurring in all socioeconomic groups. Between 1993 and 2008, the risk of caesarean section had increased more than threefold in urban areas (relative risk, RR: 3.63; 95% confidence interval, CI: 2.61-5.04) and more than 15-fold in rural areas (RR: 15.46; 95% CI: 10.46-22.86). After adjustment for improvements in income, education and access to health insurance over the study period, the RR dropped minimally in urban areas (RR: 3.07; 95% CI: 2.32-4.07), which suggests that these factors do not explain the rise; in rural areas, the adjusted RR dropped to 7.18 (95% CI: 4.82-10.69), which shows that socioeconomic change is only partly responsible for the rise. Socioeconomic region of residence was a more important driver of the caesarean section rate than individual socioeconomic status. The large variation in caesarean section rate by socioeconomic region--independent of individual income, health insurance or education--suggests that structural factors related to service supply have influenced the increasing rate more than a woman's ability to pay.

The population that lives in areas where organochlorine pesticides were spread in the past is still exposed to them through contaminated food, particulate matter, and vapors. Due to their lipophilic properties and resistance to metabolic reactions, they accumulate in tissues and fluids rich in lipids. The aim of the study was to monitor the concentrations of organochlorine pesticides in forensic adipose tissue samples of adult inhabitants of Veracruz City, Mexico, and compare their time trend levels from 1988 to 2014. During the study, hexachlorobenzene (HCB); lindane; β-hexachorocyclohexane; p,p'-dichlorodiphenyldichloroethylene (pp'DDE); p,p'-dichlorodiphenyldichloroethane (p,p'-DDT); and o,p'-dichlorodiphenyldichloroethane (o,p'-DDT) were determined. Our survey was divided into two periods: first, from the years 1988 to 1999, during which DDT was allowed to fight malaria and dengue vectors and the second from the years 2001 to 2014, after the DDT ban. A total of 1435 samples were analyzed. There were substantial differences in the forecasted time trend values of p,p'-DDE and p,p'-DDT in human adipose tissue samples in the two different periods. During the first period, p,p'-DDE decrease time trend was 1.198 mg/kg on lipid base per year; for the second one, decrease was 0.128 mg/kg on lipid base per year. p,p'-DDT decreased 0.507 mg/kg on lipid base during the first period and 0.039 mg/kg on lipid base for the second. The different concentrations may be explained by the cessation of fresh exposure after the first period and a more equilibrated decontamination tendency during the second period. This model was useful to show the decrease in the concentration of pesticides in human adipose tissue samples.

To review and compare the incidence rate of obstetric hysterectomised patients between two seven-year periods. Theperiods were from October 1, 1988 to September 30, 1995 andfrom October P', 1995 to September 30th, 2002. The data included demographic characteristics, indications, possible risk factors, complications, and operative managements. Retrospective analysis of the data that was collected from medical and labor records of the obstetric hysterectomised patientsfrom October 1, 1995 to September 30, 2002, the second seven-year period, compared with those in Pratumthong and Wattanaruangkowit's study from October 1, 1988 to September 30, 1995, the first seven-year period. Between 1998 and 2002, there were 201, 696 total deliveries with 111 obstetric hysterectomies. A significant increase in the average incidence rate of hysterectomy from 0.42 to 0.76/1000 deliveries and maternal age, placenta previa and blood transfusion in the second period compared with the first period (p < 0.05). Postoperative complications and the other risk factors of obstetric hysterectomy were not significant difference. The present study of obstetric hysterectomy demonstrates a significant increase in the incidence of hysterectomised rate, maternal age, blood transfusion, and placenta previa in the second period compared with the first period.

Uncertainty exists as to how duck harvest regulations influence waterfowl hunter behavior. We used the U.S. Fish and Wildlife Service’s Parts Collection Survey to examine how harvest regulations affected behaviors of Central Flyway duck hunters. We stratified hunters into ranked groups based on seasonal harvest and identified three periods (1975–1984, 1988–1993, 2002–2011) that represented different harvest regulations (moderate, restrictive, and liberal, respectively; season length and daily bag limits smallest in restrictive seasons and largest in liberal seasons). We examined variability of seven measures of duck hunter behaviors across the periods: days harvesting ducks, daily harvest, hunter mobility, mallard (Anas platyrhynchos) selectivity, gender selectivity, daily female mallard harvest, and timing of harvest. Hunters reported harvesting ducks on more days, at a higher efficiency, and in slightly more counties during liberal seasons relative to restrictive and moderate seasons. We provide evidence to suggest that future regulation change will affect hunter behaviors.

Paediatric dialysis and renal transplantation in the state of Rio Grande do Sul, Brazil.

PubMed

Garcia, C; Goldani, J; Garcia, V

1992-01-01

Renal replacement therapy (RRT) for Brazilian children with uraemia has been utilized since 1970 in the state of Rio Grande do Sul. One hundred and eighty patients receiving this therapy between 1970 and 1988 have been reviewed. The annual acceptance rate of new paediatric patients in this period increased from 0.6 to 6.5 patients per million child population. Glomerulonephritis (36.1%) and pyelonephritis including urological anomalies (31.7%) were the most frequent causes of end-stage renal disease. Outpatient hospital haemodialysis was the primary form of dialytic treatment in patients 5-15 years of age. Continuous ambulatory peritoneal dialysis was more often used in patients less than 5 years of age. The survival after 1 year on dialysis was 79.9% for children aged 5-15 years starting dialysis during the period 1985-1988. Fluid overload with congestive heart failure and infection were the main causes of death in children on dialysis. Eighty-four children received 93 grafts; only 14 (15%) were from cadaveric donors. One-year patient and graft survival of first living-related donor transplants were 92.2% and 78.5% respectively during the period 1985-1988. Infection accounted for 43.5% of deaths after transplantation. We conclude that RRT is becoming increasingly successful for children in our region but that greater emphasis upon patient compliance with all forms of RRT and upon cadaver kidney donation is needed.

Sharing the blame: smoking experimentation and future smoking-attributable mortality due to Joe Camel and Marlboro advertising and promotions

PubMed Central

Pierce, J.; Gilpin, E.; Choi, W.

1999-01-01

BACKGROUND—Despite public denials, internal tobacco company documents indicate that adolescents have long been the target of cigarette advertising and promotional activities. Recent longitudinal evidence suggests that 34% of new experimentation occurs because of advertising and promotions.
OBJECTIVE—To apportion responsibility for smoking experimentation and future smoking-attributable mortality among major cigarette brands attractive to young people (Camel and Marlboro).
DATA SOURCES, SETTING, AND PARTICIPANTS—Data were from confirmed never-smoking adolescents (12-17 years old) responding to the 1993 (n = 2659) and 1996 (n = 2779) population-based California Tobacco Surveys.
MAIN OUTCOMES—Adolescents named the brand of their favourite cigarette advertisements and tobacco promotional items. Using these "market shares" and the relative importance of advertising and promotions in encouraging smoking, we estimated how many new experimenters from 1988 to 1998 in the United States can be attributed to Camel and Marlboro. From other data on the natural history of smoking, we projected how many future deaths in the United States can be attributed to each brand.
RESULTS—Although Camel advertisements were favoured more than Marlboro and other brands in 1993 and 1996, the "market share" for promotional items shifted markedly during this period from Camel and other brands towards Marlboro. We estimated that between 1988 and 1998, there will be 7.9 million new experimenters because of tobacco advertising and promotions. This will result in 4.7 million new established smokers: 2.1, 1.2, and 1.4 million due to Camel, Marlboro, and other brands' advertising and promotions, respectively. Of these, 1.2 million will eventually die from smoking-attributable diseases: 520 000 from Camel, 300 000 from Marlboro, and the remainder from other brands.
CONCLUSIONS—Our analysis provides a reasonable first estimate at sharing the blame for the long-term health consequences of smoking among the major brands that encourage adolescents to start smoking.

The 1988 Antarctic ozone monitoring Nimbus-7 TOMS data atlas

NASA Technical Reports Server (NTRS)

Krueger, Arlin J.; Penn, Lanning M.; Larko, David E.; Doiron, Scott D.; Guimaraes, Patricia T.

1989-01-01

Because of the great environmental significance of ozone and to support continuing research at McMurdo, Syowa, and other Southern Hemisphere stations, the development of the 1988 ozone hole was monitored using data from the Nimbus-7 Total Ozone Mapping Spectrometer (TOMS) instrument, produced in near-real-time. This Atlas provides a complete set of daily polar orthographic projections of the TOMS total ozone measurements over the Southern Hemisphere for the period August 1 through November 17, 1988. Although total ozone in mini-holes briefly dropped below 150 DU in late August, the main ozone hole is seen to be much less pronounced than in 1987. Minimum values, observed in late September and early October 1988, were seldom less than 175 DU. Compared with the same period in 1987, when a pronounced ozone hole whose minimum value of 109 Dobson Units (DU) was the lowest total ozone ever observed, the 1988 ozone hole is displaced from the South Pole, opposing a persistent maximum with values consistently above 500 DU. Daily ozone values above selected Southern Hemisphere stations are presented, along with comparisons of the 1988 ozone distribution to that of other years.

The role of hybridization in the distribution, conservation and management of aquatic species: Symposium review

USGS Publications Warehouse

Epifanio, John; Nielsen, Jennifer L.

2001-01-01

This issue of Reviews in Fish Biology and Fisheries contains six papers addressing several critical aspects of hybridization in fishes and aquatic organisms. Hybridization is a phenomenon long recognized in fishes (Hubbs, 1920, 1955; Schwarz, 1981), as well as in other plant and vertebrate taxa, despite some rather dogmatic proclamations to the contrary, e.g., comments made by David Starr Jordan at the beginning of the 20th century that the species “line” is rarely crossed in fishes (Clark Hubbs, personal communication). Since that time, interspecific genetic introgression has been well documented in many fish genera and species: Barbus (Berrebi and CattaneoBerrebi, 1993); Cyprinodon (Echelle and Connor, 1989; Dowling and DeMarais, 1993); Gambusia (Hubbs, 1959; Scribner and Avise, 1994); Esox (Wahl and Stein, 1993); Lepomis (Avise et al., 1984); Luxilus (Duvernell and Aspinwall, 1995); Morone (Harrell et al., 1993); Notropis (Dowling et al., 1989; Dowling and Hoeh, 1991); Oncorhynchus (Busack and Gall, 1981; Campton and Utter, 1985; Loudenslager et al., 1986; Leary et al., 1987; Forbes and Allendorf, 1991; Dowling and Childs, 1992); Salmo (Nyman, 1970; Wilkins et al., 1993; Giuffra et al., 1996; Hartley, 1996; Perez et al., 1999); Salvalinus (Hammar et al., 1991; Bernatchez et al., 1995; Baxter et al., 1997; Glemet et al., 1998; Wilson and Bernatchez, 1998); Sebastes (Seeb, 1988); Stizostedion (Billington et al., 1988). See also reviews in Campton (1987), Verspoor and Hammar (1991), Smith (1992), and Scribner et al. (2000). More recently, a number of investigations have documented not only first generation hybrids, but also subsequent generation introgressant hybrids (Bartley et al., 1990; Verspoor and Hammar, 1991). As a result, our views about species typology and hybrids continue to change.

Turquoise Artifact from Teotihuacan

Turquoise artifacts appeared sporadically in Mesoamerica as early as the Formative period (Merry de Morales 1987:100, Figure 8.4; Weigand 1989:43). Most occurrences, however, postdate the collapse of Teotihuacan. In the Late Classic and Postclassic periods increasing quantities are found, often in the form of elaborate mosaics, in a wide variety of contexts in central, west and northwest Mexico. Neutron activation analysis has determined that much of this turquoise derives from sources in the southwestern United States (Weigand et al. 1977; Harbottle and Weigand 1992; Weigand and Harbottle 1993). Teotihuacan played a major role in Mesoamerica during the Terminal Formative andmore » Early-Middle Classic periods. It was the dominant power in central Mexico from about the time of Christ to its collapse at about A.D. 650 (Millon 1988, 1992; Cowgill 1996). Throughout this period goods flowed into Teotihuacan from many parts of the Mesoamerican world. Despite this widespread economic interaction, only two pieces of turquoise have been recovered in the city. In the following pages, the context and implications of one of these finds will be examined.« less

1996-01-01

This article examines trends in the nutritional status of children in EI Salvador between 1988 and 1993 (before and after the signing of a peace accord that ended the civil war.) The data derive from two national surveys, each of which included measurements of the height and weight of children aged 3-59 months. The prevalence of low weight-for-age (< -2 SD) dropped from 15% in 1988 to 10.5% in 1993. The prevalence of low weight-for-height (< -2 SD) was minimal in both surveys: falling from 3.9% to 2.9%. The prevalence of low height-for-age (< -2 SD) fell from 28.1% to 22%. These declines in malnutrition indicators resulted from an upward shift in the distributions of weight and height of children, not from thinner lower tails of the distributions. The quality of anthropometric data appears to be high for both surveys: < 1% of surveyed children had heights or weights outside the expected range. This analysis demonstrates the value of repeated surveys of nutritional status.

Ecology and control of dengue vector mosquitoes in Taiwan.

Chen, Y R; Hwang, J S; Guo, Y J

1994-12-01

Due to rapid urbanization, industrialization and social changes in recent years, the use of packing materials and tires has dramatically increased in the Taiwan area. What is more is that some parts of southern Taiwan are short of water resources and water preservation with huge containers becomes part of custom in those areas. Storage water containers, waste vessels and tires are good habitats for Aedes. Meanwhile, some persons traveling to dengue endemic countries bring the dengue disease back to Taiwan. Surveys taken since 1988 show that dengue occurs mainly in the urban and coastal areas where Aedes aegypti is prevalent. This species is the most important, if not the only, vector of dengue in Taiwan. It appears that the types of Aedes breeding have changed quickly. In dengue fever epidemic areas, the most popular breeding sites are ornamental containers (38.8%), storage water containers (30.1%), discarded containers (25.4%), receptacles (3.3%) and water collection in the basement (2.2%). In dengue fever epidemic areas, those building basements, huge water containers, waste vessels and waste tires in open fields are most difficult to clean up and manage and become the most popular Aedes habitats. We established a waste recycling system and promoted a breeding site reduction campaign for waste management, including the application of Temephos in containers to kill larvae. For the drinking water management, fish were released in water containers to prevent larval breeding. It should be mentioned that with the integrated pest control and regular inspections of Aedes larvae in Taiwan the density figures 1, 2-5, and 6 or above for Aedes aegypti were 38.7%, 42.9%, and 18.4%, respectively, in 1988, and in 1993 were 90.8%, 9.2% and 0%. The incidence of dengue fever cases has 98% decreased since 1988. In 1990 and 1993, there was no indigenous cases. We have concluded that integrated pest control is the best and most effective method for dengue fever control, including solid waste and drinking water management.

Hydrogeologic conditions and simulation of ground-water flow in the Greater Orlando Metropolitan Area, East-Central Florida

Murray, L.C.; Halford, K.J.

1996-01-01

A finite-difference ground-water flow model was used to simulate the effects of both modern-day (1988) and projected 2010 ground-water withdrawals on the Floridan aquifer system in the greater Orlando metropolitan area. This area covers about 2,500 square miles and includes all of Orange and Seminole Counties and parts of Lake, Volusia, Brevard, Osceola, and Polk Counties. The hydrogeology of the area is characterized by a thin surficial aquifer underlain by the thick, highly productive rocks of the Floridan aquifer system. Water in the Upper Floridan aquifer is brackish (chloride concentrations greater than 1,000 milligrams per liter) in discharge areas beneath and near the St. Johns and Wekiva Rivers and is freshest (chloride concentrations less than 100 milligrams per liter) inrecharge areas. A slight trend toward increasing concentrations of dissolved solids, chloride, and sulfate has been observed at Upper Floridan aquifer springs. Chloride concentrations in the Upper Floridan aquifer measured between 1966 and 1993 at the Cocoa well field have increased from 50 milligrams per liter to 120 milligrams per liter; concentrations measured in the Lower Floridan aquifer between 1966 and 1993 have increasedfrom 600 milligrams per liter to 3,000 milligrams per liter. The flow model was calibrated by comparing (a) simulated and estimated Upper Floridan aquifer predevelopment (unstressed) potentiometric surfaces, (b) simulated and measured heads at 142 Upper Floridan aquifer monitoring wells in 1988 (averageabsolute error of 1.8 feet), (c) simulated and measured discharge rates at 15 Upper Floridan aquifer springs in 1988 (306 cubic feet per second), and (d) simulated and measured drawdowns at 134 Upper Floridan aquifer monitoring wells between 1988 and May 1990 (58 and 95 percent of simulated drawdowns were within plus or minus 25and 50 percent of measured drawdowns, respectively). Relative to predevelopment conditions, model simulations indicate that about half of the 305 million gallons per day of water pumped from the Floridan aquifer system in 1988 was accounted for by increased recharge from the surficial aquifer system. About 23 cubic feet persecond was derived from increased lateral inflow. A storage coefficient of 1x10-3 provided the best comparisons of measured-to-simulated data during the transient simulation from January to May 1990. This storativity probably is greater than the true storativity of the Upper Floridan aquifer because storage contributions from the intermediateconfining unit were not accounted for during model design and development. Calibrated transmissivity ranged from 10,000 to greater than 400,000 feet squared per day in the Upper Floridan aquifer, and from 5,000 to 600,000 feet squared per day in the Lower Floridan aquifer. Calibrated intermediate confining unit leakance ranged from 1x10-5 to 4x10-3 per day and was highest in areas where the unit is thin or has been breached by numerous sinkholes. In general,calibrated transmissivity and leakance values were higher than associated aquifer-test values. Simulated recharge rates to the Upper Floridan aquifer from the surficial aquifer system ranged from less than 3 to 21 inches per year. Recharge rates of greater than 10 inches per year were simulated in areas of west Seminole, west Orange, east Lake, and southwest Volusia Counties. Recharge rates of less than 3 inches per year were simulated in east Orange and northeast Osceola Counties. The calibrated model was used to simulate the effects of increased Floridan aquifer withdrawals in the year 2010 (542 million gallons per day) on water levels and spring flow. Projected effects were simulated for both "wet" conditions (using 1988 fixed-head arrays) and for "dry" conditions (using May 1990 fixed-head arrays), thus bracketing a potential range of effects. Relative to simulated 1988 conditions, simulated 2010 spring flow decreased by 43 cubic f

Background Although CT can be greatly beneficial, its relatively high radiation doses have caused public health concerns. Objective To assess patterns in CT usage among patients aged less than 22 years in Northern England during the period 1993–2002. Materials and methods Electronic data were obtained from radiology information systems of all nine National Health Service trusts in the region. Results A total of 38,681 scans had been performed in 20,483 patients aged less than 22 years. The number of CT examinations rose, with the steepest increase between 1997 and 2000. The number of patients scanned per year increased less dramatically, with 2.24/1,000 population aged less than 22 years having one scan or more in 1993 compared to 3.54/1,000 in 2002. This reflects an increase in the median number of scans per patient, which rose from 1 in 1993 to 2 by 1999. More than 70% of CT examinations were of the head, with the number of head examinations varying with time and patient age. Conclusion The frequency of CT scans in this population more than doubled during the study period. This is partly, but not wholly, explained by an increase in the number of scans per patient.

[French immigration policy].

Weil, P

1994-01-01

From the late nineteenth century through 1974, France permitted immigration to furnish workers and to compensate for the low level of fertility. Intense immigration from North Africa, the economic crisis of the 1970s, and other factors led to policy changes in 1974. French immigration policy since 1974 has fluctuated between guaranteeing foreigners equal rights regardless of their religion, race, culture, or national origin, and attempting to differentiate among immigrants depending on their degree of assimilability to French culture. From 1974 to 1988, France had five different policies regarding whether to permit new immigration and what to do about illegal immigrants. In July 1984, the four major political parties unanimously supported a measure in Parliament that definitively guaranteed the stay in France of legal immigrants, whose assimilation thus assumed priority. Aid for return to the homeland was no longer to be widely offered, and immigration of unskilled workers was to be terminated except for those originating in European Community countries. Major changes of government in 1988 and 1993 affected only the modalities of applying these principles. The number of immigrants has fluctuated since 1974. Unskilled workers, the only category whose entrance was specifically controlled by the 1984 measures, have declined from 174,000 in 1970 to 25,000 in the early 1990s. The number of requests for political asylum declined from 60,000 in 1989 to 27,000 in 1993, and in 1991, 15,467 persons were granted refugee status. The number of immigrants of all types permitted to remain in France declined from 250,000 or 3000 per year in the early 1970s to around 110,000 at present. Although the decline is significant, it appears insufficient to the government in power since 1993. Although migratory flows are often explained as the product of imbalance in the labor market or in demographic growth, the French experience suggests that government policies, both in the sending and receiving countries, are a more potent determinant.

Water Levels In Major Artesian Aquifers Of The New Jersey Coastal Plain, 1988

Rosman, Robert; Lacombe, Pierre J.; Storck, Donald A.

1995-01-01

Water levels in 1,251 wells in the New Jersey Coastal Plain, Philadelphia County, Pennsylvania, and Kent and New Castle Counties, Delaware, were measured from October 1988 to February 1989 and compared with 1,071 water levels measured from September 1983 to May 1984. Water levels in 916 of the wells measured in the 1983 study were remeasured in the 1988 study. Alternate wells were selected to replace wells used in 1983 that were inaccessible at the time of the water-level measurements in 1988 or had been destroyed. New well sites were added in strategic locations to increase coverage where possible. Large cones of depression have formed or expanded in the nine major artesian aquifers that underlie the New Jersey Coastal Plain. Water levels are shown on nine potentiometric-surface maps. Hydrographs for observation wells typically show water-level declines for 1983, through 1989. In the confined Cohansey aquifer, the lowest water level, 20 feet below sea level, was measured in a well located at Cape May City Water Department, Cape May County. Water levels in the Atlantic City 800-foot sand declined as much as 21 feet at Ventnor, Atlantic County, over the 6-year period from the 1983 study to this study for 1988. Water levels in the Piney Point aquifer were as low as 56 feet below sea level at Seaside Park, Ocean County; 45 feet below sea level in southern Cumberland County; and 28 feet below sea level at Margate, Atlantic County. Water levels in the Vincentown aquifer did not change over the 6-year period. The lowest water levels in the Wenonah-Mount Laurel aquifer and the Englishtown aquifer system were 218 feet and 256 feet below sea level, respectively. Large cones of depression in the Potomac- Raritan-Magothy aquifer system are centered in the Camden County area and the Middlesex and Monmouth County area. Water levels declined as much as 46 feet in these areas over the 6-year period.

Internal Consistency of the NVAP Water Vapor Dataset

NASA Technical Reports Server (NTRS)

Suggs, Ronnie J.; Jedlovec, Gary J.; Arnold, James E. (Technical Monitor)

2001-01-01

The NVAP (NASA Water Vapor Project) dataset is a global dataset at 1 x 1 degree spatial resolution consisting of daily, pentad, and monthly atmospheric precipitable water (PW) products. The analysis blends measurements from the Television and Infrared Operational Satellite (TIROS) Operational Vertical Sounder (TOVS), the Special Sensor Microwave/Imager (SSM/I), and radiosonde observations into a daily collage of PW. The original dataset consisted of five years of data from 1988 to 1992. Recent updates have added three additional years (1993-1995) and incorporated procedural and algorithm changes from the original methodology. Since each of the PW sources (TOVS, SSM/I, and radiosonde) do not provide global coverage, each of these sources compliment one another by providing spatial coverage over regions and during times where the other is not available. For this type of spatial and temporal blending to be successful, each of the source components should have similar or compatible accuracies. If this is not the case, regional and time varying biases may be manifested in the NVAP dataset. This study examines the consistency of the NVAP source data by comparing daily collocated TOVS and SSM/I PW retrievals with collocated radiosonde PW observations. The daily PW intercomparisons are performed over the time period of the dataset and for various regions.

Analysis of urban-rural population dynamics for China.

Shen, J

1991-12-01

The population dynamics of China are presented in a multiregional demographic model using regional estimates or mortality and migration based on the 1% population sample survey in 1987. An open ended population account is generated for period cohort a, gender g of region i (urban) and j (rural) using population, birth, death, and migration. Demographic rates and equations for flows of nonsurviving migrants of period cohort a of gender g are estimated using the forward demographic rate definition. Out-migration rates for period cohort a of gender g are defined by migration flow divided by the initial population. The death rate for period cohort A1 and A are estimated using a single region method. Death and migration rates are simultaneously estimated with an iterative procedure. The population accounts estimates and demographic rates are provided for the period ending 1986-87 for male births, males in period cohorts 10 and 20, female births, and females in period cohorts 10 and 20. The urban and rural population projection model is based on the population accounts concept and assumes fixed rates of mortality, migration, and normal fertility for the base year 1987. The results of this projection are a population of 1090 million that will grow to 1304 million in 2000, 1720 million in 2050, and 1791 million in 2087. Urban population will expand from 44.2% in 1988 to 46.6% in 2000, and 54.7% in 2087. The labor population of males 18-65 years and females 18-60 years will increase from 58.8% in 1988 to 59.7% in 2000 and decline to 58.4% by 2087. The old age population of males 65 years and females 60 years will increase from 6.5% in 1988 to 7.9% in 2000, and 16.3% in 2087. The mean age increased from 28.3 years in 1988 to 37 in 2087. Urban population may be underprojected; migration problems are recognized. Fertility also is likely to decline. An alternative projection (B) is given to account for the U-shape distribution and urban fertility of 1.8 in 2000, increasing to and stabilizing at 2.2 in 2020, such that population estimates for 2000 are 1291 and 1524 for 2087 with a peak in 2048 of 1573. A faster fertility decline is also used to generate projection C. The author's projections A, B, and C, which are based on more recent data and a more realistic model, are than the "objective projection" and than the "warning projection" generated by China's Population Census Office based on 1982 census data.

Generation of an empirical soil moisture initialization and its potential impact on subseasonal forecasting skill of continental precipitation and air temperature

NASA Astrophysics Data System (ADS)

Boisserie, Marie

The goal of this dissertation research is to produce empirical soil moisture initial conditions (soil moisture analysis) and investigate its impact on the short-term (2 weeks) to subseasonal (2 months) forecasting skill of 2-m air temperature and precipitation. Because of soil moisture has a long memory and plays a role in controlling the surface water and energy budget, an accurate soil moisture analysis is today widely recognized as having the potential to increase summertime climate forecasting skill. However, because of a lack of global observations of soil moisture, there has been no scientific consensus on the importance of the contribution of a soil moisture initialization as close to the truth as possible to climate forecasting skill. In this study, the initial conditions are generated using a Precipitation Assimilation Reanalysis (PAR) technique to produce a soil moisture analysis. This technique consists mainly of nudging precipitation in the atmosphere component of a land-atmosphere model by adjusting the vertical air humidity profile based on the difference between the rate of the model-derived precipitation rate and the observed rate. The unique aspects of the PAR technique are the following: (1) based on the PAR technique, the soil moisture analysis is generated using a coupled land-atmosphere forecast model; therefore, no bias between the initial conditions and the forecast model (spinup problem) is encountered; and (2) the PAR technique is physically consistent; the surface and radiative fluxes remains in conjunction with the soil moisture analysis. To our knowledge, there has been no attempt to use a physically consistent soil moisture land assimilation system into a land-atmosphere model in a coupled mode. The effect of the PAR technique on the model soil moisture estimates is evaluated using the Global Soil Wetness Project Phase 2 (GSWP-2) multimodel analysis product (used as a proxy for global soil moisture observations) and actual in-situ observations from the state of Illinois. The results show that overall the PAR technique is effective; across most of the globe, the seasonal and anomaly variability of the model soil moisture estimates well reproduce the values of GSWP-2 in the top 1.5 m soil layer; by comparing to in-situ observations in Illinois, we find that the seasonal and anomaly soil moisture variability is also well represented deep into the soil. Therefore, in this study, we produce a new global soil moisture analysis dataset that can be used for many land surface studies (crop modeling, water resource management, soil erosion, etc.). Then, the contribution of the resulting soil moisture analysis (used as initial conditions) on air temperature and precipitation forecasts are investigated. For this, we follow the experimental set up of a model intercomparison study over the time period 1986-1995, the Global Land-Atmosphere Coupling Experiment second phase (GLACE-2), in which the FSU/COAPS climate model has participated. The results of the summertime air temperature forecasts show a significant increase in skill across most of the U.S. at short-term to subseasonal time scales. No increase in summertime precipitation forecasting skill is found at short-term to subseasonal time scales between 1986 and 1995, except for the anomalous drought year of 1988. We also analyze the forecasts of two extreme hydrological events, the 1988 U.S. drought and the 1993 U.S. flood. In general, the comparison of these two extreme hydrological event forecasts shows greater improvement for the summertime of 1988 than that of 1993, suggesting that soil moisture contributes more to the development of a drought than a flood. This result is consistent with Dirmeyer and Brubaker [1999] and Weaver et al. [2009]. By analyzing the evaporative sources of these two extreme events using the back-trajectory methodology of Dirmeyer and Brubaker [1999], we find similar results as this latter paper; the soil moisture-precipitation feedback mechanism seems to play a greater role during the drought year of 1988 than the flood year of 1993. Finally, the accuracy of this soil moisture initialization depends upon the quality of the precipitation dataset that is assimilated. Because of the lack of observed precipitation at a high temporal resolution (3-hourly) for the study period (1986-1995), a reanalysis product is used for precipitation assimilation in this study. It is important to keep in mind that precipitation data in reanalysis sometimes differ significantly from observations since precipitation is often not assimilated into the reanalysis model. In order to investigate that aspect, a similar analysis to that we performed in this study could be done using the 3-hourly Tropical Rainfall Measuring Mission (TRMM) dataset available for a the time period 1998-present. Then, since the TRMM dataset is a fully observational dataset, we expect the soil moisture initialization to be improved over that obtained in this study, which, in turn, may further increase the forecast skill.

Flow-system analysis of the Madison and Minnelusa aquifers in the Rapid City area, South Dakota--conceptual model

USGS Publications Warehouse

Long, Andrew J.; Putnam, Larry D.

2002-01-01

The conceptual model of the Madison and Minnelusa aquifers in the Rapid City area synthesizes the physical geography, hydraulic properties, and ground-water flow components of these important aquifers. The Madison hydrogeologic unit includes the karstic Madison aquifer, which is defined as the upper, more permeable 100 to 200 ft of the Madison Limestone, and the Madison confining unit, which consists of the lower, less permeable part of the Madison Limestone and the Englewood Formation. Overlying the Madison hydrogeologic unit is the Minnelusa hydrogeologic unit, which includes the Minnelusa aquifer in the upper, more permeable 200 to 300 ft and the Minnelusa confining unit in the lower, less permeable part. The Madison and Minnelusa hydrogeologic units outcrop in the study area on the eastern flank of the Black Hills where recharge occurs from streamflow losses and areal recharge. The conceptual model describes streamflow recharge, areal recharge, ground-water flow, storage in aquifers and confining units, unsaturated areas, leakage between aquifers, discharge from artesian springs, and regional outflow. Effective transmissivities estimated for the Madison aquifer range from 500 to 20,000 ft2/d and for the Minnelusa aquifer from 500 to 10,000 ft2/d. Localized anisotropic transmissivity in the Madison aquifer has tensor ratios as high as 45:1. Vertical hydraulic conductivities for the Minnelusa confining unit determined from aquifer tests range from 1.3x10-3 to 3.0x10-1 ft/d. The confined storage coefficient of the Madison and Minnelusa hydrogeologic units was estimated as 3x10-4 ft/d. Specific yield was estimated as 0.09 for the Madison and Minnelusa aquifers and 0.03 for the Madison and Minnelusa confining units. Potentiometric surfaces for the Madison and Minnelusa aquifers have a general easterly gradient of about 70 ft/mi with local variations. Temporal change in hydraulic head in the Madison and Minnelusa aquifers ranged from about 5 to 95 ft in water years 1988-97. The unconfined areas were estimated at about 53 and 36 mi2 for the Madison and Minnelusa hydrogeologic units, respectively, in contrast to an aquifer analysis area of 629 mi2. Dye-tracer tests, stable isotopes, and hydrogeologic features were analyzed conjunctively to estimate generalized ground-water flowpaths in the Madison aquifer and their influences on the Minnelusa aquifer. The western Rapid City area between Boxelder Creek and Spring Creek was characterized as having undergone extensive tectonic activity, greater brecciation in the Minnelusa Formation, large transmissivities, generally upward hydraulic gradients from the Madison aquifer to the Minnelusa aquifer, many karst springs, and converging flowpaths. Water-budget analysis included: (1) a dry-period budget for declining water levels; October 1, 1987, to March 31, 1993; (2) a wet-period budget for rising water levels, April 1, 1993, to September 30, 1997; and (3) a full 10-year period budget for water years 1988-97. By simultaneously balancing these water budgets, initial estimates of recharge, discharge, change in storage, and hydraulic properties were refined. Inflow rates for the 10-year budget included streamflow recharge of about 45 ft3/s or 61 percent of the total budget and areal recharge of 22 ft3/s or 30 percent. Streamflow recharge to the Madison hydrogeologic unit was about 86 percent of the total streamflow recharge. Outflow for the 10-year budget included springflow of 31 ft3/s or 42 percent of the total budget, water use of about 10 ft3/s or 14 percent, and regional outflow of 22 ft3/s or 30 percent. Ground-water storage increased 9 ft3/s during the 10-year period, and net ground-water movement from the Madison to Minnelusa hydrogeologic unit was about 8 ft3/s.

The genus Fennerogalathea Baba, 1988 was known to contain two species: F. chacei Baba, 1988, the type species, from the Philippines, Taiwan and Indonesia and F. chirostyloides Tirmizi & Javed, 1993 from the Bay of Bengal. In the present study, three new species of the genus are described and illustrated: F. chani n. sp. from Papua New Guinea, F. cultrata n. sp. from New Caledonia and Vanuatu and F. ensifera n. sp. from Fiji. The new species are morphologically distinguishable on the basis of the shape and spination of the rostrum and the presence/absence of a small spine on the frontal margin of the carapace. The species also show clear genetic differences (COI and 16S rDNA) among them.

Urban and resort development and drought conditions have placed increasing demands on the surface-water and groundwater resources of the Eagle Creek Basin, in southcentral New Mexico. The Village of Ruidoso, New Mexico, obtains 60-70 percent of its water from the Eagle Creek Basin. The village drilled four production wells on Forest Service land along North Fork Eagle Creek; three of the four wells were put into service in 1988 and remain in use. Local citizens have raised questions as to the effects of North Fork well pumping on flow in Eagle Creek. In response to these concerns, the U.S. Geological Survey, in cooperation with the Village of Ruidoso, conducted a hydrologic investigation from 2007 through 2009 of the potential effect of the North Fork well field on streamflow in North Fork Eagle Creek. Mean annual precipitation for the period of record (1942-2008) at the Ruidoso climate station is 22.21 inches per year with a range from 12.27 inches in 1970 to 34.81 inches in 1965. Base-flow analysis indicates that the 1970-80 mean annual discharge, direct runoff, and base flow were 2,260, 1,440, and 819 acre-ft/yr, respectively, and for 1989-2008 were 1,290, 871, and 417 acre-ft/yr, respectively. These results indicate that mean annual discharge, direct runoff, and base flow were less during the 1989-2008 period than during the 1970-80 period. Mean annual precipitation volume for the study area was estimated to be 12,200 acre-feet. Estimated annual evapotranspiration for the study area ranged from 8,730 to 8,890 acre-feet. Estimated annual basin yield for the study area was 3,390 acre-ft or about 28 percent of precipitation. On the basis of basin-yield computations, annual recharge was estimated to be 1,950 acre-ft, about 16 percent of precipitation. Using a chloride mass-balance method, groundwater recharge over the study area was estimated to average 490 acre-ft, about 4.0 percent of precipitation. Because the North Fork wells began pumping in 1988, 1969-80 represents the pre-groundwater-pumping period, and 1988-2009 represents the groundwater-pumping period. The 5-year moving average for precipitation at the Ruidoso climate station shows years of below-average precipitation during both time periods, but no days of zero flow were recorded for the 11-year period 1970-80 and no-flow days were recorded in 11 of 20 years for the 1988-2009 period.

The impact of HMO penetration on the rate of hospital cost inflation, 1985-1993.

PubMed

Gaskin, D J; Hadley, J

1997-01-01

This paper provides evidence that growth in health maintenance organization (HMO) enrollment slows hospital cost inflation. During the period 1985-1993, hospitals in areas with high rates of HMO penetration and growth had a slower rate of growth in expenses (8.3%) than hospitals in low penetration areas (11.2%). From 1992-1993, HMO growth lowered the rate of hospital cost inflation by .34 to 3.40 percentage points, depending on the base-year level and the annual change in HMO penetration. Declines in Medicare Prospective Payment System (PPS) margins also lowered hospital cost inflation; over the time period, annual hospital cost inflation was reduced by .38 percentage points. The estimates imply that the cumulative effect of HMO growth on hospital costs has been a $56.2 billion reduction (in 1993 dollars).

We modelled postfledging survival and age-specific breeding probabilities in endangered Roseate Terns (Sterna dougallii) at Falkner Island, Connecticut, USA using capture-recapture data from 1988-1998 of birds ringed as chicks and as adults. While no individuals bred as 2-year-olds during this period, about three-quarters of the young that survived and returned as 3-year-olds nested, and virtually all surviving birds had begun breeding by the time they reached 5 years of age. We found no evidence of temporal variation age of first breeding of birds from different cohorts. There was significant temporal variation in the annual survival of adults and the survival over the typical 3-year maturation period of prebreeding birds, with extremely low values for both groups from the 1991 breeding season. The estimated overwinter survival rate (0.62) for adults from 1991-1992 was about three-quarters the usual rate of about 0.83, but the low survival of fledglings from 1991 resulted in less than 25% of the otherwise expected number of young from that cohort returning as breeding birds; this suggests that fledglings suffered a greater proportional decrease in survival than did adults. The survival estimates of young from 1989 and 1990 show that these cohorts were not negatively influenced by the events that decimated the young from 1991, and the young from 1992 and 1993 had above-average survival estimates. The apparent decrease since 1996 in development of fidelity of new recruits to this site is suspected to be due mainly to nocturnal disturbance and predation of chicks causing low productivity.

An investigation of temporal dynamics of El Niño-Southern Oscillation (ENSO) and spatial patterns of dryness/wetness period over arid and semi-arid zones of Central Asia and their relationship with Normalized Difference Vegetation Index (NDVI) values (1982-2011) have explored in this article. For identifying periodical oscillations and their relationship with NDVI values have selected El Nino 3.4 index and thirty years of new generation bi-weekly NDVI 3g acquired by the Advanced Very High Resolution Radiometer (AVHRR) satellites time-series data. Based on identification ONI (Oceanic Nino Index) is a very strong El Nino (warm) anomalies observed during 1982-1983, 1997-1998 and very strong La Nino (cool) period events have observed 1988-1989 years. For correlation these two factors and seeking positive and negative trends it has extracted from NDVI time series data as "low productivity period" following years: 1982-1983, 1997 -1998; and as "high productivity period" following years: 1988 -1989. Linear regression observed warm events as moderate phase period selected between moderate El Nino (ME) and NDVI with following periods:1986-1987; 1987-1988; 1991-1992; 2002-2003; 2009-2010; and moderate La Niña (ML) periods and NDVI (1998-1999; 1999-2000; 2007-2008) which has investigated a spatial patterns of wetness conditions. The results indicated that an inverse relationship between very strong El Nino and NDVI, decreased vegetation response with larger positive ONI value; and direct relationship between very strong La Niña and NDVI, increased vegetation response with smaller negative ONI value. Results assumed that significant impact of these anomalies influenced on vegetation productivity. These results will be a beneficial for efficient rangeland/grassland management and to propose drought periods for assessment and reducing quantity of flocks' due to a lack of fodder biomass for surviving livestock flocks on upcoming years in rangelands. Also results demonstrate that a non-anthropogenic drivers of variability effected to land surface vegetation signals, understanding of which will be beneficial for efficient rangeland and agriculture management and establish ecosystem services in precipitation-driven drylands of Central Asia.

Social inequalities in life expectancy and mortality during the transition period of economic crisis (1993–2010) in Korea

PubMed Central

2012-01-01

Backgrounds This study examines social inequalities in life expectancy and mortality during the transition period of the Korean economic crisis (1993–2010) among Korean adults aged 40 and over. Methods Data from the census and the national death file from the Statistics Korea are employed to calculate life expectancy and age-specific-death-rates (ASDR) by age, gender, and educational attainment for five years: 1993, 1995, 2000, 2005, and 2010. Absolute and relative differences in life expectancy and Age-Specific Death Rates by educational attainment were utilized as proxy measures of social inequality. Results Clear educational gradient of life expectancy was observed at age 40 by both sexes and across five time periods (1993, 1995, 2000, 2005, and 2010). The gradient became notably worse in females between 1993 and 2010 compared to the trend in males. The educational gradient was also found for ASDR in all five years, but it was more pronounced in working age groups (40s and 50s) than in elderly groups. The relative disadvantage of ASDR among working age Korean adults, both males and females, became substantially worse over time. Conclusions Social inequalities in life expectancy and ASDR of the working age group across socioeconomic status over time were closely related to the widening of the social difference created by the macroeconomic crisis and the expansion of neo-liberalism in Korea.

To examine recent turnover trends among chairs of academic pediatric departments. Membership data for the 150 institutions represented by the Association of Medical School Pediatric Department Chairs in the United States, Canada, and Puerto Rico were reviewed for the time period of 1993-2003. From 1993 to 2003, 278 individuals (250 men and 28 women) held the position of chair. The mean time of service was 5.58 +/- 3.2 years (median: 5 years). Twenty-nine individuals served continuously as chairs during the 11-year period. Seventy-two individuals served as interim chairs. Twenty-eight women were appointed either chairs or interim chairs during the 11 years. The number of female chairs decreased from 13 in 1993 to 11 in 2003. Female chairs were in office 3.42 +/- 2.72 years. A total of 123 departments had a change in leadership, with a mean annual turnover rate of 17% (range: 4.6-24%). Three departments had 5 different leaders as either interim chair or chair and 6 departments had 4 different leaders during this time period. Neonatology was the most common subspecialty represented by recent pediatric chairs, although nephrology was the subspecialty with the greatest proportional representation. Departments of pediatrics have high turnover of leadership. Women, in particular, serve for relatively short periods and appear to be under-represented within the leadership of pediatrics. Efforts should be made to ascertain personal qualities that allow sustained leadership and to attract more women into leadership positions.

Primary glomerular disease (PGD) is the leading cause of end-stage renal disease (ESRD) in China. With the development of socioeconomic status of Chinese people in the last two decades, PGD in ESRD is intent to decrease. However, whether this affects the spectrum of PGD is not clear. The aim of the current study is to investigate the changing spectrum of PGD in China. The records of 5398 consecutive native renal biopsies performed in adults (>or=14 years of age) in our centre between 1993 and 2007 were retrospectively analysed. The criteria for renal biopsy and pathologic diagnosis were kept unchanged. The patients were grouped according to a 5-year interval, 1993-97 (period 1), 1998-2002 (period 2) and 2003-07 (period 3). Then they were divided into four groups according to age for stratified analysis: 14-24 years, 25-44 years, 45-59 years and the elderly (>or=60 years). Three thousand, three hundred and thirty-one patients were diagnosed with PGD. PGD remained the most common renal disease, accounting for 65.9%, 57.7% and 63.2% in period 1, 2 and 3, respectively, without any significant difference. The proportion of elder patients increased significantly from 0% in 1993 to 9.1% in 2007 (P < 0.001). Within 1993-97, the leading PGD was IgA nephropathy (50.7%), followed by non-IgA MsPGN (19.9%), membranous nephropathy (MN) (13.3%) and minimal change disease (MCD) (6.3%), while within 2003-07, the most common PGD was still IgAN (58.2%), but followed by MN (14.3%), MCD (13.4%) and non-IgA MsPGN (7.0%). The age-adjusted frequency of IgAN and MCD increased significantly from period 1 to period 3 (P < 0.01 and P < 0.001, respectively), while that of non-IgA MsPGN, EnPGN and MPGN decreased significantly (P < 0.001, P < 0.01 and P < 0.05, respectively). There was no significant change in the age-adjusted frequency of FSGS, MN and CreGN during the study period. However, when patients were stratified by age, a sixfold increase in frequency of FSGS was identified in the 14- to 24-year group (P < 0.01). The spectrum of primary glomerulonephritis has changed within the last 15 years. The relative frequency of non-IgA MsPGN, EnPGN and MPGN decreased significantly, while that of MCD and IgA nephropathy increased significantly. The relative frequency of FSGS increased significantly in younger patients.

Experimental Injury Biomechanics of the Pediatric Neck

Motor vehicle related crashes rank as the most common cause of spinal related injuries in the pediatric population (Platzer et al. 2007; Brown et al. 2001; Kokoska et al. 2001; Eleraky et al. 2000; Hamilton and Myles 1992a; Bonadio 1993; Babcock 1975). Pediatric spinal related trauma accounts for between 1 and 12 % of all spinal related injuries (Hamilton and Myles 1992a; Hadley et al. 1988; Aufdermaur 1974). Cervical spine trauma in children accounts for approximately 2 % of all cervical spinal injuries (Henrys et al. 1977). Approximately 1-2 % of all children admitted for traumatic injury are related to injuries to the cervical spine (Platzer et al. 2007; Brown et al. 2001; Kokoska et al. 2001; Orenstein et al. 1994; Rachesky et al. 1987). Overall, pediatric neck injury rates are significantly lower than adult rates; however, the neck injury rate in children between the ages of 11 and 15 years approaches the adult rate of 18.8 per 100,000 (McGrory et al 1993; Myers and Winkelstein 1995). For children less than 11 years of age, neck injuries are relatively rare (1.2 per 100,000), but have particularly devastating consequences (McGrory et al. 1993). The overall mortality rate amongst victims of pediatric spinal trauma is approximately 16-41 % but considerably higher for the youngest ages (Platzer et al. 2007; Brown et al. 2001; Kokoska et al. 2001; Eleraky et al. 2000; Givens et al. 1996; Orenstein et al. 1994; Hamilton and Myles 1992b).

OBJECTIVES: This study examined the trend in cesarean section deliveries and the factors associated with it in the Minhang District of Shanghai, China. METHODS: A representative sample of the members of 2716 households in the district were interviewed in the fall of 1993. This study analyzed the data from 1959 married women of reproductive age with at least one live birth. RESULTS: During the past 3 decades, the proportion of infants born by cesarean section increased from 4.7% to 22.5%. Logistic regression analysis revealed that the highest cesarean section rate, which occurred in the most recent period of 1988 through 1993, was associated with form of medical payment, self-reported complications during pregnancy, higher birthweight, and maternal age. Government insurance pays all costs of cesarean sections and accounted for the highest proportion of the cesarean section rate. CONCLUSIONS: The high rates of cesarean sections in China are surprising given the lack of the factors that usually lead to cesarean sections. The increasing cesarean section rates may be an early indication that emerging forms of health insurance and fee-for-service payments to physicians will lead to an excessive emphasis on costly, high-technology medical care in China.

To study the trend of mortality changes on lung cancer during the period 1972 to 2011 in Qidong. Cancer registration data from 1972 - 2011 in Qidong was used to analyze the following information as: crude mortality rate (CR) of lung cancer, the age-standardized rates by China population (CASR) and the World population (WASR), the truncated mortality rate of 35 - 64, the accumulative rate of age from 0 to 74 years old, the accumulative risk, and the total percentage over all sites of cancers. The changes on the trend of mortality by gender, age and period were analyzed. The CR of lung cancer was 31.15 per 100 000 (males: 45.68, females: 16.95). While CASR and WASR were 14.04, and 22.95 per 100 000, respectively. The truncated rate was 31.82 per 100 000. Accumulative rate, accumulative risk, and total percentage were 2.93%, 2.89%, and 20.50% respectively. The mortality rate of lung cancer in males was significantly higher than that in females, with a sex ratio of 2.69:1. CRs increased remarkably with age among those 30-year-olds, with P value being 0.000. When compared with 9 periods of 1972, 1973 - 1977, 1978 - 1982, 1983 - 1987, 1988 - 1992, 1993 - 1997, 1998 - 2002, 2003 - 2007, and 2008 - 2011, the CRs, CASRs and WASRs increased 6.78-folds, 1.60-folds and 1.92-folds, respectively, with the average annual percentage changes (APC) as 4.78%, 1.86% and 2.04%, respectively. The mortality rate of lung cancer among residents during the last four decades in Qidong had been increasing remarkably, suggesting that special attention on lung cancer trend should be highly paid.

In 1988, Pluto's atmosphere was surmised to exist because of the surface ices that had been detected through spectroscopy, but it had not yet been directly detected in a definitive manner. The key to making such a detection was the stellar occultation method, used so successfully for the discovery of the Uranian rings in 1977 (Elliot et al. 1989; Millis et al. 1993) and before that for studies of the atmospheres of other planets.On 9 June 1988, Pluto occulted a star, with its shadow falling over the South Pacific Ocean region. One team of observers recorded this event from the Kuiper Airborne Observatory, while other teams captured the event from various locations in Australia and New Zealand. Preceding this event, extensive astrometric observations of Pluto and the star were collected in order to refine the prediction.We will recount the investigations that led up to this important Pluto occultation, discuss the unexpected atmospheric results, and compare the 1988 event to the recent 2015 event whose shadow followed a similar track through New Zealand and Australia.

Human immunodeficiency virus type 1 (HIV-1) can be transmitted through blood transfusion. The first transfusion-acquired immunodeficiency syndrome (AIDS) patient in Taiwan was a 46-year-old woman who received two units of whole blood during a hysterectomy at a provincial hospital in 1985. In 1991, she experienced a herpes zoster infection. In March 1993, she had extensive herpetic gingivostomatitis and another herpes zoster attack, and was treated at the same hospital. Two months later, she had oral candidiasis and was treated at a medical center. She was not tested for HIV-1 infection until she developed Pneumocystis carinii pneumonia in June 1993. In February 1994, and developed cytomegalovirus retinitis and died 6 months later. Donor blood given to the patients during the hysterectomy was HIV-1 positive. The donor's HIV infection was discovered in 1991 and he died of AIDS in 1993. As blood centers in Taiwan did not start screening for HIV-1 until January 1988, it is urgently recommended that any individual who received a blood transfusion between 1984 and 1987 in Taiwan and who currently experiences repeated episodes of opportunistic infections have an HIV-1 blood test. The receipt of a blood transfusion between 1984 and 1987 should be listed by the Department of Health as an indication for HIV-1 screening.

Secular changes in the height of Polish schoolboys from 1955-1988

Secular changes in height have been observed in many regions of Poland using cross-sectional data; however, data from four nationally representative surveys conducted from 1955 to 1988 have only been partially analyzed. Dramatic social and economic transitions during this 33 year period provide a unique opportunity to understand changes in growth within this historic context. We analyzed the changes in height of boys, aged 7 to 18 years, from surveys conducted in 1955, 1966, 1978 and 1988. Data for height were converted to Z-scores using the LMS method and the 2000 National Center for Health Statistics reference. In each consecutive survey year, boys at all ages were significantly taller than the same aged boys from the previous survey year, with mean height increases of a 2.35 cm, 3.43 cm and 1.47 cm between 1955-1966, 1966-1978 and 1978-1988, respectively. There were significant declines with age in height Z-scores from 7 to 14 years of age, followed by improvements relative to the reference between 14 and 18 years of age. The decline in Z-scores may be partially explained by an effect of delayed maturation. However, historic context also supports that some birth cohorts likely experienced a more adverse environment during early childhood than did other birth cohorts. PMID:21752733

Update on clinical attire requirements in dental hygiene programs.

Foley, E S

1994-01-01

Many changes have occurred in the clinical appearance of dental hygienists in the past few years because of increased emphasis on infection control and disease prevention. The purpose of this study was to assess dental hygiene program clinical attire requirements in 1993 and to compare them with requirements as described by a 1988 survey. Checklist questionnaires were mailed to the directors of all 211 dental hygiene programs in the United States and Puerto Rico in October 1993. Questions were asked regarding clinical attire requirements for students and faculty, including uniforms, gowns, lab coats, masks, protective eyewear, shoes, hair coverings, laundry management, and changes under consideration. Percentages were calculated by region and for all responding programs. Of 211 questionnaires mailed, 178 were returned, for a response rate of 84%. Results indicated that students and faculty are currently wearing more colorful uniforms and scrubs than in 1988. Long-sleeved lab coats, disposable gowns, and washable surgical gowns are increasing in use. Glasses and face masks were required for all students and faculty in both surveys, but chin-length face shields are increasing in use as optional face protection. In most instances, face shields are worn with face masks. Laundry services are being provided for faculty (employees); however, most students continue to be responsible for their own laundry after being instructed to follow stringent guidelines taught by the faculty.

Among other things, this Act adds the following new section to the Saint Lucia Criminal Code: "112A. Any person who commits an act of indecency with or towards a child under the age of fourteen or who incites or encourages a child under that age to commit such an act with him or with another person is liable on conviction on indictment to imprisonment for two years or on summary conviction to imprisonment for six months or to a fine not exceeding one thousand dollars." The Act also changes the criminal penalty for keeping a brothel. Henceforth a person who is guilty of the crime is subject to a fine not exceeding $5,000 or to imprisonment for twelve months. In addition, that person may be required "to enter into a recognisance with or without securities to be of good behaviour for any period not exceeding one year; and in default of compliance with such recognisance is liable to imprisonment for a further period not exceeding six months." full text

Slip-rate increase at Parkfield in 1993 detected by high-precision EDM and borehole tensor strainmeters

On two of the instrument networks at Parkfield, California, the two-color Electronic Distance Meter (EDM) network and Borehole Tensor Strainmeter (BTSM) network, we have detected a rate change starting in 1993 that has persisted at least 5 years. These and other instruments capable of measuring crustal deformation were installed at Parkfield in anticipation of a moderate, M6, earthquake on the San Andreas fault. Many of these instruments have been in operation since the mid 1980s and have established an excellent baseline to judge changes in rate of deformation and the coherence of such changes between instruments. The onset of the observed rate change corresponds in time to two other changes at Parkfield. From late 1992 through late 1994, the Parkfield region had an increase in number of M4 to M5 earthquakes relative to the preceding 6 years. The deformation-rate change also coincides with the end of a 7-year period of sub-normal rainfall. Both the spatial coherence of the rate change and hydrological modeling suggest a tectonic explanation for the rate change. From these observations, we infer that the rate of slip increased over the period 1993-1998.On two of the instrument networks at Parkfield, California, the two-color Electronic Distance Meter (EDM) network and Borehole Tensor Strainmeter (BTSM) network, we have detected a rate change starting in 1993 that has persisted at least 5 years.

An analysis of reported cases of cutaneous leishmaniasis (CL) was performed using the data registered in the southern Ecuadorian Amazon region during 27 years from 1986 to 2012. The cases/subjects with both the suspected CL lesions and the amastigote-positive results were recruited for the analysis. The yearly occurrence of cases showed a markedly higher number during the six years, 1988 and 1993. After 1994 when the insecticide spraying campaign using helicopter in 1993-1994, the number dropped remarkably. Then, the yearly occurrence gradually fluctuated from 101 cases in 1996 to 11 in 2009, maintaining a low number of cases after the campaign. The monthly occurrence of cases showed a markedly high number during March and August, suggesting a correlation to the rainy season (months) in the areas. A statistical significance was found between the monthly average number of the CL case and the average precipitation (p=0.01474). It was suggested that the time of transmission of CL would depend on the rainy seasons at each endemic area of Ecuador, which has a diverse climatic feature depending on the geographic regions. Such information at given leishmaniasis-endemic areas of Ecuador would be important for the future planning of the disease control. Molecular analysis and characterization of clinical samples revealed the presence of Leishmania (Viannia) braziliensis. Copyright © 2015 Elsevier B.V. All rights reserved.

Trends in the nutritional status of Salvadorian children: the post-war experience.

This article examines trends in the nutritional status of children in EI Salvador between 1988 and 1993 (before and after the signing of a peace accord that ended the civil war.) The data derive from two national surveys, each of which included measurements of the height and weight of children aged 3-59 months. The prevalence of low weight-for-age (< -2 SD) dropped from 15% in 1988 to 10.5% in 1993. The prevalence of low weight-for-height (< -2 SD) was minimal in both surveys: falling from 3.9% to 2.9%. The prevalence of low height-for-age (< -2 SD) fell from 28.1% to 22%. These declines in malnutrition indicators resulted from an upward shift in the distributions of weight and height of children, not from thinner lower tails of the distributions. The quality of anthropometric data appears to be high for both surveys: < 1% of surveyed children had heights or weights outside the expected range. This analysis demonstrates the value of repeated surveys of nutritional status. PMID:8823958

Children born after assisted reproductive technology, particularly singletons, have been shown to have an increased risk of congenital malformations compared with children born after spontaneous conception. We wished to study whether there has been a change in the past 20 years in the risk of major congenital malformations in children conceived after assisted reproductive technology compared with children spontaneously conceived. Population-based cohort study including 90 201 assisted reproductive technology children and 482 552 children spontaneously conceived, born in Denmark, Finland, Norway and Sweden. Both singletons and twins born after in vitro fertilization, intracytoplasmatic sperm injection and frozen embryo transfer were included. Data on children were taken from when the national Nordic assisted reproductive technology registries were established until 2007. Multiple logistic regression analyses were used to estimate the risks and adjusted odds ratios for congenital malformations in four time periods: 1988-1992, 1993-1997, 1998-2002 and 2003-2007. Only major malformations were included. The absolute risk for singletons of being born with a major malformation was 3.4% among assisted reproductive technology children vs. 2.9% among children spontaneously conceived during the study period. The relative risk of being born with a major congenital malformation between all assisted reproductive technology children and children spontaneously conceived remained similar through all four time periods (p = 0.39). However, we found that over time the number of children diagnosed with a major malformation increased in both groups across all four time periods. When comparing children conceived after assisted reproductive technology and spontaneously conceived, the relative risk of being born with a major congenital malformation did not change during the study period. © 2018 Nordic Federation of Societies of Obstetrics and Gynecology.

Precise monitoring of global temperature trends from satellites

Spencer, Roy W.; Christy, John R.

1990-01-01

Passive microwave radiometry from satellites provides more precise atmospheric temperature information than that obtained from the relatively sparse distribution of thermometers over the earth's surface. Accurate global atmospheric temperature estimates are needed for detection of possible greenhouse warming, evaluation of computer models of climate change, and for understanding important factors in the climate system. Analysis of the first 10 years (1979 to 1988) of satellite measurements of lower atmospheric temperature changes reveals a monthly precision of 0.01 C, large temperature variability on time scales from weeks to several years, but no obvious trend for the 10-year period. The warmest years, in descending order, were 1987, 1988, 1983, and 1980. The years 1984, 1985, and 1986 were the coolest.

A prospective study was conducted to assess the evolution of the incidence of type 1 diabetes mellitus (insulin-dependent) in Málaga among children less than 14 years of age between 1982 and 1993. The capture-recapture method was chosen for estimating the probability of ascertainment and two sources were used: The hospital registry and Málaga Diabetes Association members. We detected 437 children and the ascertainment achieved was 98.8%. The average annual incidence was 14.3/10(5) and the prevalence at the end of the period was 0.78 patients/10(3). During the last 6 years of the observation period, the incidence rose by 42%. The highest incidence was found among children between 10 and 13 years of age in both sexes. The age of onset and female/male ratio increased during the study period. There was an inverse relationship with monthly temperature. In comparison with other European epidemiological studies, we found a higher incidence and increased rate of growth of the incidence of type 1 diabetes mellitus during the observation period.

Electric power monthly, June 1988

1988-09-15

Total net generation by electric utilities in the United States for the month of June 1988 was 232,183 gigawatthours, 3 percent higher than the amount reported a year ago. Although temperatures (measured by cooling degree days) for June 1988 were 9 percent warmer than normal, they were 3 percent cooler than for June 1987. A large portion of that higher demand for electricity was met by nuclear-powered generation. Net generation from nuclear power during June 1988 (44,079 gigawatthours) was only 1 percent below the record set in January of this year, and 21 percent above that reported in June 1987more » (36,560 gigawatthours). The only energy source other than nuclear that reported higher levels of net generation during June 1988 was coal, up 2 percent over the same period last year. Warmer-than-normal temperatures did, however, have an affect on various parts of the country. For example, on Wednesday, June 22, 1988, unseasonably high temperatures forced the Pennsylvania, New Jersey, and Maryland Interconnection (PJM) into a system-wide 5-percent voltage reduction for 2 hours. Contributing to that reduction in voltage was the shutdown of the Three Mile Island, Unit 1, for refueling and the closing of the Peach Bottom Units 2 and 3 by the Nuclear Regulatory Commission. Three Mile Island, Unit 1, normally provides the PJM system with about 800 megawatts while the two Peach Bottom units, combined, provide approximately 2100 megawatts. 10 refs., 1 fig., 27 tabs.« less

Tuberculosis control in the era of the HIV epidemic: risk of tuberculosis infection in Tanzania, 1983-1998.

PubMed

2001-02-01

In Tanzania, a national tuberculosis programme (NTP) was established in 1979 based on the principles currently known as the World Health Organization DOTS strategy. From the period 1983-1987 to 1994-1998, notification rates of smear-positive tuberculosis increased from 32 to 69 per 100,000 population, mainly due to the human immunodeficiency virus (HIV) epidemic. To estimate the trend in the annual risk of tuberculosis infection and to establish to what extent the opposing forces of improved tuberculosis control and HIV have had an impact on tuberculosis transmission. Three national surveys were conducted in Tanzania among primary school children at 5-year intervals. The annual risk of tuberculosis infection and its trend were determined by tuberculin skin testing. The annual risk of infection in children without BCG scar using the criterion '17 mm + 2 x 18 mm' or more was estimated at 1.1% in 1983-1987, 1.0 in 1988-1992, and 0.9% in 1993-1998. There appears to have been little change in the annual risk of infection over the study period, either when using other criteria to define infection or in children with a BCG scar. The estimated number of infections per notified case decreased over time from 36 to 19. Despite strongly increased tuberculosis notification rates in adults, associated with the HIV epidemic, the risk of tuberculosis infection in children appears to have been stable over the past 15 years in Tanzania. This remarkable achievement is probably due to the impact of the NTP on tuberculosis transmission.

From 1988 to 1993 thirty liver resections were performed in thirty patients. Eight were operated for suffering from hepatocellular carcinoma, four from metastasis of colon's adenocarcinoma, five for great hemangiomas and the rest for focal liver changes. Right lobectomy was performed in six cases, as well as two trisegmentectomies and two left lobectomies while segmentectomies in the rest. Periopretive mortality occurred in two cases as two patients died because of postoperative thrombosis of vena portae and massive gastrointestinal bleeding. Recidive of malignant tumors was established in five patients after year and in other five till the second year. Benign tumors are without recidives. Later resection is a safe procedure with a considerable selection of patients, with use of latest technical conveniences, application of grafts on branches of vena portae and with routine application of intraoperative ultrasonography. The paper contains diagnostical postulates, surgical techniques and anatomic and morphologic types of resection.

Thermal Efficiency of Lava Tubes of the Pu'u O'o-Kupaianaha Eruption, Kilauea Volcano, Hawaii

We have applied glass geothermometry to a suite of very glassy lava samples collected from the upper (pond) and lower (coast) ends of the Episode 48 tube system, throughout the lifetime of the Kupaianaha pond, and also to a small suite of skylight samples collected from various tubes active between 1987 and 1993. The results for the pond-coast pairs are: (1) From November 1986 through January 1988 (15 months), the average change in glass quenching temperature from pond to coast (for 12 pairs) is 12.4°C. The average increase in crystallinity (inferred from observed enrichment of TiO2 and K2O in the coastal glasses) is 11-12% by weight. (2) For the 23 months from February 1988 through November 1989, the average change in inferred quenching temperature (for 25 pairs) is 8.4°C. The average increase in crystallinity is 4-5% by weight. Within this part of the data set, pond and coastal temperatures rise and fall together much of the time, even though these temporal fluctuations are at or below the limit of resolution of glass geothermometry (ΔT < 3 degrees). (3) The minimum difference in temperature for any pond-coast pair is 7°C. Twenty-four (out of 37) pairs have ΔT = 7-9°C, over the three year period. About half of the skylight samples have glass MgO contents consistent with their linear position along the tube system. In other samples, the skylight glasses are displaced to lower MgO contents, suggesting that such samples are not consistently as well-quenched as the pond and littoral spatter samples. For the data from 1992-93, the new tube system was 2 km shorter than the earlier, Kupaianaha-fed tubes. The best-documented ΔT of 6°C for some 1993 samples observed for this 10-km long tube, gives exactly the same temperature decrease with distance (0.6°/km) as the limiting ΔT of 7°C observed for the 12-km Kupaianaha tube systems. This cooling rate may represent the limiting thermal efficiency of tubes of the current Kilauea East Rift eruption.

1994-01-01

Recently, scientists from more than a dozen countries carried out the field phase of a project called the Coupled-Atmosphere Response Experiment (COARE), devoted to describing the ocean-atmosphere system of the western Pacific near-equatorial warm pool. The project was conceived, organized, and funded under the auspices of the International Tropical Ocean Global Atmosphere (TOGA) Program. Although COARE consisted of several field phases, including a year-long atmospheric enhanced monitoring period (1 July 1992 -- 30 June 1993), the heart of COARE was its four-month Intensive Observation Period (IOP) extending from 1 Nov. 1992 through 28 Feb. 1993. An overview of large-scale variability during COARE is presented. The weather and climate observed in the IOP is placed into context with regard to large-scale, low-frequency fluctuations of the ocean-atmosphere system. Aspects of tropical variability beginning in Aug. 1992 and extending through Mar. 1993, with some sounding data for Apr. 1993 are considered. Variability over the large-scale sounding array (LSA) and the intensive flux array (IFA) is emphasized.

The Ohio University College of Osteopathic Medicine ranks high among the nation's 19 osteopathic medical schools with respect to the percentage of underrepresented minorities (URMs) in the entering class. The college has strong recruitment and retention programs for URM and disadvantaged students. URM enrollment rose steadily from 11% in 1982-83 to 22% in 1997-98, despite the school's location in a rural, residential public university with few minorities as students or town residents. The college has six programs to support minority students through both undergraduate and medical school: the Summer Scholars Program (1983 to present), an intensive six-week summer program to prepare rising under-graduate seniors and recent graduates to apply to medical school; Academic Enrichment (1987 to present), to support first- and second-year medical students; the Prematriculation Program (1988 to present), an intensive six-week summer program for students who will matriculate in the college; Program ExCEL (1993 to present), a four-year program for undergraduates at Ohio University; the Summer Enrichment Program (1993 to present), an optional six-week program for students who will enter the premedical course at Ohio University; and the Post-baccalaureate Program (1993 to present), a year-long, individually tailored program for URM students who have applied to the medical college but have been rejected. The medical college first focused on supporting students already in the medical school curriculum, then expanded logically back through the undergraduate premedical programs, always targeting learning strategies and survival strategies, peer and faculty support, and mastery of the basic science content. The college plans to create an on-site MCAT preparation program and perhaps expand into secondary education.

Plant and environment interactions: Growth and yield response of commercial bearing-age {open_quote}Casselman{close_quote} plum trees to various ozone partial pressures

Nursery stock of plum (Prunus salicina Lindel., cv. Casselman) was planted 1 Apr. 1988 in an experimental orchard at the Univ. of California Kearney Agricultural Center near Fresno, CA. Trees in this study were enclosed in open-top fumigation chambers on 1 May 1989, and exposed to three atmospheric ozone partial pressures (charcoal filtered air, ambient air, and ambient air + ozone) during the 1989 through 1992 growing seasons (typically 1 Apr. - 1 Nov.). A nonchamber treatment plot was used to assess chamber effects on tree performance. This study details the results of the exposures during the initial commercial bearingmore » period (1991 through 1993) in this orchard. The mean 12-h (0800-2000 h Pacific Daylight Time [PDT]) ozone partial pressures during the experimental periods in the charcoal filtered, ambient, ambient + ozone, and nonchamber treatments averaged 0.031, 0.048, 0.091, and 0.056 {mu}Pa Pa{sup {minus}1} in 1991 and 1992, respectively. Fruit number per tree decreased as atmospheric ozone partial pressure increased from the charcoal filtered to ambient + ozone treatment, significantly affecting yield. Yield of plum trees averaged 23.6, 19.8, 13.7, and 17.9 kg tree{sup {minus}1} in 1991 and 1992 in the charcoal filtered, ambient, ambient + ozone, and nonchamber treatments, respectively. Only one out of the five original treatment plots was exposed to ozone treatments during the 1993 growing season. Yield of plum trees in this single replicate in 1993 was reduced by increased atmospheric ozone partial pressure. Yield of plum trees in the four remaining unexposed treatment plots in 1993 was 16.7, 17.9, and 16.0 kg tree{sup {minus}1} in the previous charcoal filtered, ambient, and ambient + ozone treatments respectively. The similarity in yield of the post-chamber treatments indicates that a change in air quality in the current growing season can affect yield of Casselman plum trees. 26 refs., 6 figs., 4 tabs.« less

The longer road to medical school graduation.

Kassebaum, D G; Szenas, P L

1994-10-01

The authors followed the academic progress and graduation rates of students matriculating in U.S. medical schools each year between 1976 and 1988. The four-year graduation rates of medical students in MD programs declined from 91.4% for students who matriculated in 1976 to 81.2% for 1988 matriculants. During the same period, the percentage graduating in five years increased from 5.5% to 10.6%, while those still enrolled or on leaves of absence after five years rose from 1.9% to 4.1%. The lengthening of undergraduate medical education is associated with students' spending extra time on special studies or research, but to a greater extent graduation has been delayed for remediation of academic difficulty or slowing of the pace of education to overcome handicaps in academic preparation and learning skills. Underrepresented minority students, particularly black Americans, have lower four-year graduation rates than majority students, and the rate has fallen steadily across successive classes matriculating between 1976 and 1988. The longer periods of undergraduate medical education since 1984, however, have been accompanied by a reversal of the growing attrition rate for black-American students, probably the result of more appropriate pacing of education over the first year or two and the wider availability of student academic support. The longer road to graduation also accumulates greater educational costs, contributing to the escalation in student indebtedness that has been out of proportion to increases in tuition and fees.(ABSTRACT TRUNCATED AT 250 WORDS)

Minimum prevalence of chromosome 22q11 deletions

Submicroscopic deletions from within chromosome 22q11 are associated with DiGeorge (DGS), velocardiofacial (VCFS) and conotruncal anomaly syndromes and isolated congenital heart defects. In 1993 our pediatric cardiologists clinically referred all children in whom a chromosome 22q11 deletion was suspected for fluorescent in situ hybridization studies using probes from the DGS critical region. 10 affected individuals have been identified to date from the children born in 1993 in the Northern Region served exclusively by our center. A further case, the subsequent pregnancy in one of these families was affected and terminated on the basis of a major heart malformation. In themore » years 1988-92, for which we have complete ascertainment, there were 1009 heart defects among 191,700 births (mean 202 per annum). Thus we estimate that chromosome 22q11 deletions were the cause of at least 5% of congenital heart disease. As not all children with chromosome 22q11 deletions have a heart defect, this gives an estimated minimum prevalence of 1/4000 live births.« less

Study Objectives: To investigate changes over 15 years in the prevalence of insomnia and its association with demographic characteristics and hypnotic medication use. Design: Analysis of 3 cross-sectional national mental health surveys carried out in 1993, 2000, and 2007, which used comparable sampling methods and identical insomnia assessments. Setting: Adults living in private households in England. Patients or Participants: 20,503 people aged 16-64 years. Measurements and Results: Insomnia was defined according to 4 different criteria, using relevant questions from the revised Clinical Interview Schedule. Modest increases in insomnia prevalence were found over the survey periods (any symptoms increasing from 35.0% in 1993 to 38.6% in 2007; insomnia diagnosis from 3.1% to 5.8%, respectively). In all 3 surveys, similar strengths of association in relation to all criteria were found, with female gender, increased age, lower educational attainment, depression, unemployment, economic inactivity, and widowed, divorced, or separated status. Prevalence of hypnotic use was double in 2000 (0.8%) compared to 1993 (0.4%); from limited information on selected medications, there was no such increase between 2000 and 2007. The reasons reported for any sleep disturbance over the last month were generally similar across surveys, the most marked change being illness/discomfort increasing as an explanation from 14.3% to 17.4% to 19.0%. Conclusions: In the English general population, insomnia (by any definition) showed a modest but steady increase in prevalence over a 15-year period. Strengths of associations with demographic factors and self-reported reasons for sleep disturbance remained reasonably stable over this period.

Has the perinatal outcome of children conceived after assisted reproductive technology (ART) improved over time? The perinatal outcomes in children born after ART have improved over the last 20 years, mainly due to the reduction of multiple births. A Swedish study has shown a reduction in unwanted outcomes over time in children conceived after ART. Our analyses based on data from more than 92 000 ART children born in four Nordic countries confirm these findings. Nordic population-based matched cohort study with ART outcome and health data from Denmark, Finland, Norway and Sweden. We analysed the perinatal outcome of 62 379 ART singletons and 29 758 ART twins, born from 1988 to 2007 in four Nordic countries. The ART singletons were compared with a control group of 362 215 spontaneously conceived singletons. Twins conceived after ART were compared with all spontaneously conceived twins (n = 122 763) born in the Nordic countries during the study period. The rates of several adverse perinatal outcomes were stratified into the time periods: 1988-1992; 1993-1997; 1998-2002 and 2003-2007 and presented according to multiplicity. For singletons conceived after ART, a remarkable decline in the risk of being born preterm and very preterm was observed. The proportion of ART singletons born with a low and very low birthweight also decreased. Finally, the stillbirth and infant death rates have declined among both ART singletons and twins. Throughout the 20 year period, fewer ART twins were stillborn or died during the first year of life compared with spontaneously conceived twins, presumably due to the lower proportion of monozygotic twins among the ART twins. We were not able to adjust for some potential confounders such as BMI, smoking, length or cause of infertility. The Nordic ART populations have changed over time, and in recent years, both less as well as severely reproductive ill couples are being treated. This may have affected the observed trends. It is assuring that data from four countries confirm an overall improvement over time in the perinatal outcomes of children conceived after ART. Furthermore, data show the beneficial effect of single embryo transfer, not only in regard to lowering the rate of multiples but also concerning the health of singletons. The European Society for Human Reproduction and Embryology (ESHRE), the University of Copenhagen and the Danish Agency for Science, Technology and Innovation has supported the project.

Akhavan, D; Musgrove, P; Abrantes, A; d'A Gusmão, R

Malaria transmission was controlled elsewhere in Brazil by 1980, but in the Amazon Basin cases increased steadily until 1989, to almost half a million a year and the coefficient of mortality quadrupled in 1977-1988. The government's malaria control program almost collapsed financially in 1987-1989 and underwent a turbulent reorganization in 1991-1993. A World Bank project supported the program from late 1989 to mid-1996, and in 1992-1993, with help from the Pan American Health Organization, facilitated a change toward earlier and more aggressive case treatment and more concentrated vector control. The epidemic stopped expanding in 1990-1991 and reversed in 1992-1996. The total cost of the program from 1989 through mid-1996 was US$616 million: US$526 million for prevention and US$90 million for treatment. Compared to what would have happened in the absence of the program, nearly two million cases of malaria and 231,000 deaths were prevented; the lives saved were due almost equally to preventing infection and to case treatment. Converting the savings in lives and in morbidity into Disability-Adjusted Life Years yields almost nine million DALYs, 5.1 million from treatment and 3.9 million from prevention. Nearly all the gain came from controlling deaths and therefore from controlling falciparum. The overall cost-effectiveness was US$2672 per life saved or US$69 per DALY, which is low compared to most previous estimates and compares favorably to many other disease control interventions. Contrary to much previous experience, case treatment appears more cost-effective than vector control, particularly where falciparum is prevalent and unfocussed insecticide spraying is relatively ineffective. Halting the epidemic by better targeted vector control and emphasizing treatment paid off in much reduced mortality from malaria and in significantly lower costs per life saved.

This report summarizes the monitoring of fish kills in upper East Fork Poplar Creek (EFPC) from July 1990 to June 1993. Since the opening of Lake Reality (LR) in 1988, total numbers of fish inhabiting upper EFPC have increased. However, species diversity has remained poor. Water quality data have been collected in upper EFPC during the time period covered in this report. Total residual chlorine (TRC) levels have exceeded federal and state water quality criteria over the years. However, with the installation of two dechlorination systems in late 1992, TRC levels have been substantially lowered in most portions of uppermore » EFPC. By June 1993, concentrations of TRC were 0.04 to 0.06 mg/L at the north-south pipes (NSP) and below detection limits at sampling station AS-8 and were 0 to 0.01 mg/L at the inlet and outlet of LR. The daily chronic fish mortality in upper EFPC has been attributed to background stress resulting from the continuous discharge of chlorine into upper EFPC. Mean daily mortality rates for 22 acute fish kills were three fold or more above background and usually exceeded ten fish per day. Total number of dead fish collected per acute kill event ranged from 30 to over 1,000 fish; predominant species killed were central stonerollers (Campostoma anomalum) and striped shiners (Luxilus chrysocephalus). Spills or elevated releases of toxic chemicals, such as acids, organophosphates, aluminum nitrate, ammonia, or chlorine, were identified as possible causative agents; however, a definitive cause-effect relationship was rarely established for any acute kills. Ambient toxicity testing, in situ chemical monitoring, and streamside experiments were used to examine TRC dynamics and ambient toxicity in EFPC.« less

Potential effects of extremely low frequency (ELF) electromagnetic fields on periphyton were studied from 1983 to 1993 using a Before, After, Control and Impact design. The study was conducted at two sites on the Ford River, a fourth-order brown water trout stream in Dickinson County, Michigan. The Reference site received 4.9-6.5 times less exposure to ground electric fields and from 300 to 334 times less exposure to magnetic flux from 1989 to 1993 when the antenna was operational at 76 Hz than did the Antenna site. The objective of the study was to determine if ELF electromagnetic fields had caused changes in structure and/or function of algal communities in the Ford River. Significant differences in chlorophyll a standing crop and daily accumulation rate (a surrogate for primary productivity), and organic matter standing crop and daily accumulation rate were observed between the Reference and Antenna site after the antenna became operational. These four related community function variables all increased at the Antenna site with largest and most consistent increases occurring for chlorophyll measures. Compared to pre-operational data, the increase in chlorophyll at the Antenna site also occurred during a period of low amperage testing in 1986-1988, and did not increase further when the antenna became fully operational in 1989, indicating a low threshold for response. There was no significant differences between the Antenna and Reference sites in community structure variables such as diversity, evenness and the relative abundance of dominant diatoms. Thus, 76 Hz ELF electromagnetic radiation apparently did not change the basic makeup of the diatom community but did increase accumulation rates and standing crops of chlorophyll a and organic matter.

HIV-1 epidemics among men who have sex with men (MSM) continue to expand in developed and developing countries. Although HIV infection in MSM is amongst the highest of the key affected populations in many countries in Southeast Asia, comprehensive molecular epidemiological study of HIV-1 among MSM remains inadequate in the region including in Malaysia. Here, we reported the phylodynamic profiles of HIV-1 genotypes circulating among MSM population in Kuala Lumpur, Malaysia. A total of n = 459 newly-diagnosed treatment-naïve consenting subjects were recruited between March 2006 and August 2012, of whom 87 (18.9%) were self-reported MSM. Transmitted drug resistance mutations were absent in these isolates. Cumulatively, phylogenetic reconstructions of the pro-rt gene (HXB2∶2253–3275) showed that HIV-1 subtype B and CRF01_AE were predominant and contributed to approximately 80% of the total HIV-1 infection among MSM. In addition to numerous unique transmission lineages within these genotypes, twelve monophyletic transmission clusters of different sizes (2–7 MSM sequences, supported by posterior probability value of 1) were identified in Malaysia. Bayesian coalescent analysis estimated that the divergence times for these clusters were mainly dated between 1995 and 2005 with four major transmission clusters radiating at least 12 years ago suggesting that active spread of multiple sub-epidemic clusters occurred during this period. The changes in effective population size of subtype B showed an exponential growth within 5 years between 1988 and 1993, while CRF01_AE lineage exhibited similar expansion between 1993 and 2003. Our study provides the first insight of the phylodynamic profile of HIV-1 subtype B and CRF01_AE circulating among MSM population in Kuala Lumpur, Malaysia, unravelling the importance of understanding transmission behaviours as well as evolutionary history of HIV-1 in assessing the risk of outbreak or epidemic expansion.

From Greenhouse to Icehouse: Evidence of Climatic Changes Across the Marine Eocene-Oligocene Transition From the Massignano GSSP Section (Central Italy)

Coccioni, R.; Marsili, A.; Montanari, A.

2004-12-01

The transition from global "greenhouse" conditions of the early and middle Eocene to global "icehouse" conditions of the early Oligocene marks a turning point in Cenozoic Earth history which was marked by reorganization of global ocean circulation patterns and significant turnovers in the marine and terrestrial biota (Prothero et al., 2003) and led to the development of the first East Antarctic ice-sheet, close to the Eocene/Oligocene boundary (33.7 Ma). The Massignano GSSP for the Eocene/Oligocene boundary (Premoli Silva & Jenkins, 1993), exposed in an abandoned quarry in the Monte Conero area, on the Adriatic coast of central Italy, was investigated at high-resolution in order to provide evidence for climatic changes across the marine Eocene-Oligocene transition. The Massignano section is 23-m thick and consists of alternating reddish/greenish-grey marls and calcareous marls with several biotite-rich levels of volcanic origin which were deposited in a lower bathyal depositional setting, at a paleodepth of 1000-2000 m (Coccioni & Galeotti, 2003). A complete geological record of 3 myr (from 36.2 to 33.2 Ma according to the time scale of Berggren et al., 1995) is preserved which spans the interval from the latest Eocene to the early Oligocene, from Chron C16n to C13n (Bice & Montanari, 1988; Lowrie & Lanci, 1994), and is provided by an accurate calibration of bio- and geochemical events. Cosmic signatures are also recorded in the Massignano section (Montanari et al., 1993) where three impactoclastic, iridium-rich layers occurs in the middle-lower part of the succession (Montanari et al., 1988, 1993; Bodeselitsch et al., 2004). They are possibly linked to the Popigai and Chesapeake Bay impacts and related to a comet shower over a duration of 2.2 myr (Farley et al., 1998). Calcareous nannofossil and foraminiferal assemblages (Coccioni et al., 2000; Spezzaferri et al., 2002), dinoflagellate cyst palynology (Brinkhuis & Biffi, 1993), ostracod faunas (Dall'Antonia et al., 2003), oxygen and carbon isotopes (Bodeselitsch et al., 2004), and environmental magnetism (Jovane et al., 2004) provide evidence of a major cooling trend with warm pulses. These pulses seems to be global in extent and may have been triggered by multiple impact events during the Late Eocene comet shower that may have played an important role related to the deterioration of the global climate at the end of the Eocene Epoch. The release of methane hydrate during and after an impact in a continental shelf (like the Chesapeake Bay impact) or seafloor, or impacts of 12C-rich comets may account for the observed negative isotope excursions.

The paper is focusing on the representativeness of single lidar stations and SBUV overpasses in searching for trends in the vertical ozone profiles. It was found that from the lower to the upper stratosphere single or grouped stations correlate well with zonal means calculated from SBUV overpasses in a global perspective. The best representativeness in vertical ozone profiles is found within 5 degrees of latitude north or south of any LIDAR station or SBUV overpasses at which the latitude range is expanded as we move to the upper stratospheric layers. The paper includes a detailed analysis on a ranking of proxy footprints in the vertical ozone profiles. Major proxies studied are of different kinds: those outside of the earth system (solar cycle), those who represent dynamic processes (the QBO, the AO, AAO, ENSO), the volcanic aerosol component (AOD) and the manmade contribution to chemistry (EESC). The trends have been studied after removal of proxies from the total available SBUV records during the period 1980-2015. As seen in the detailed contributions of the proxies major contributions come from chemistry, the solar cycle and AOD. It appears that at some particular years the synergistic contribution of proxies which although contribute smaller amplitudes to ozone individually, when composited can result to anomalies that may influence the long term change or trend in the ozone profiles. Notable periods for the synergistic negative anomalies can be seen in 1983, 1985, 1988, 1992, 1993, 1995, 1997, 1999, 2002, 2004, 2006, 2008, 2011, 2013. During all these years ozone at about 24 km dropped below -6% of the mean. The so-called "inflection point" between 1997 and 1999 marks the large reduction of the significant negative ozone trends, followed by the recent period of positive ozone change 1998-2015 which is observed above 15 hPa whose significance remains to be proven due to its smaller period in comparison to the total period of 36 years of ozone profiles (1980-2015).

To assess the relationship between positional blood pressure change and 8-year incidence of hypertension in a biracial cohort of young adults. Participants from the Coronary Artery Risk Development in Young Adults (CARDIA) study with complete data from year 2 (1987-1988), year 5 (1990-1991), year 7 (1992-1993), and year 10 (1995-1996) examinations were included (N = 2781). Participants were classified into 3 groups based on their year 2 systolic blood pressure response to standing: drop, a decrease in systolic blood pressure of more than 5 mm Hg; same, a change of between -5 and +5 mm Hg; and rise, more than 5-mm Hg increase. The number of participants in each group was as follows: drop, 741; same, 1590; and rise, 450. The 8-year incidence of hypertension was 8.4% in the drop group, 6.8% in the same group, and 12.4% in the rise group (P < .001). Adjusted odds ratios for developing hypertension during the follow-up period in the rise group vs the same group were as follows: in black men, 2.85 (95% confidence interval [CI], 1.43-5.69), in black women, 2.47 (95% CI, 1.19-5.11), in white men, 2.17 (95% CI, 1.00-4.73), and in white women, 4.74 (95% CI, 1.11-20.30). A greater than 5-mm Hg increase in blood pressure on standing identified a group of young adults at increased risk of developing hypertension within 8 years. These findings support a physiologic link between sympathetic nervous system reactivity and risk of hypertension in young adults.

Due to the close relationship of climate change with reference evapotranspiration (ETo), detecting changes in ETo spatial distribution and its temporal evolution at local and regional levels is favorable to comprehensively understand climate change-induced impacts on hydrology and agriculture. In this study, the objective is to identify whether climate change has caused variation of ETo spatial distribution in different analysis periods [i.e., long- (20-year), medium- (10-year), and short-term (5-year)] and to investigate its temporal evolution (namely, when these changes happened) at annual and monthly scales in Southwest China (SWC). First, we estimated ETo values using the United Nations Food and Agriculture Organization (FAO) Penman-Monteith equation, based on historical climate data measured at 269 weather sites during 1973-2012. The analysis of variance (ANOVA) results indicated that the spatial pattern of annual ETo had significantly changed during the past 40 years, particularly in west SWC for the long-term analysis period, and west and southeast SWC in both medium- and short-term periods, which corresponded to the percent area of significant differences which were 21.9, 58.0, and 48.2 %, respectively. For investigating temporal evolution of spatial patterns of annual ETo, Duncan's multiple range test was used, and we found that the most significant changes appeared during 1988-2002 with the significant area of higher than 25.0 %. In addition, for long-, medium-, and short-term analysis periods, the spatial distribution has significantly changed during March, September, November, and December, especially in the corresponding periods of 1988-1997, 1983-1992, 1973-1977, and 1988-2002. All in all, climate change has resulted in significant ETo changes in SWC since the 1970s. Knowledge of climate change-induced spatial distribution of ETo and its temporal evolution would aid in formulating strategies for water resources and agricultural managements.

Trends in the Relationship Between Obesity and Disability, 1988-2012.

PubMed

Chang, Virginia W; Alley, Dawn E; Dowd, Jennifer Beam

2017-09-15

Rising obesity rates, coupled with population aging, have elicited serious concern over the impact of obesity on disability in later life. Prior work showed a significant increase in the association between obesity and disability from 1988 to 2004, calling attention to disability as a cost of longer lifetime exposure to obesity. It is not known whether this trend has continued. We examined functional impairment and impairment in activities of daily living (ADL) (defined as severe or moderate to severe) for adults aged 60 years or older (n = 16,770) over 3 time periods in the National Health and Nutrition Examination Survey. The relative odds of impairment for obese individuals versus normal-weight individuals significantly increased from period 1 (1988-1994) to period 2 (1999-2004) for all outcomes. In period 3 (2005-2012), this association remained stable for functional and severe ADL impairment and decreased for moderate-to-severe ADL impairment. The fraction of population disability attributable to obesity followed a similar trend. The trend of an increasing association between obesity and disability has leveled off in more recent years, and is even improving for some measures. These findings suggest that public health and policy concerns that obesity would continue to become more disabling over time have not been borne out. © The Author(s) 2017.

During and following the 1988 Yellowstone National Park wildfires, airborne remotely sensed data were collected in order to characterize various vegetative components, fire front movements and bum intensities. ER-2 derived Thematic Mapper Simulator (TMS) data were used in conjunction with water sampling and chemistry analysis to determine fire intensities in various watersheds and aquatic system condition changes. The airborne Daedalus multispectral TMS data allowed the characterization of various bum intensities in watersheds. Stream sampling was then conducted in those various burned watersheds to determine nitrate and phosphate concentration changes. Six stream watersheds were monitored for five years (1989-1993) during non-snow periods (May/June through September): Cache Creek (intensely burned), Blacktail Deer Creek (intensely burned), Snake River (moderately burned), Lamar River (mixed burning), Soda Butte Creek (lightly burned), and Amphitheatre Creek (unburned). One litre samples were collected from those streams with ISCO water samplers every 12 hours. The samples were removed every 14 days .(28 Samples), and water chemistry analysis was performed. Chemistry analysis indicated that nitrate and phosphate concentrations were elevated in moderately burned watersheds and significantly elevated in severely burned watersheds. The results during the five year study indicate that bum intensities regulate stream water nitrate and phosphate concentrations, and that remotely sensed data can be used effectively to predict watershed chemical changes which will affect aquatic conditions.

Prior research has often overlooked potential cohort differences in marijuana views and use across adolescence and young adulthood. To begin to address this gap, we conduct an exploratory examination of marijuana views and use among American youth using a panel of cross-sectional surveys. Findings are based on repeated, cross-sectional data collected annually from adolescents (ages 12-17; n=230,452) and young adults (ages 18-21; n=120,588) surveyed as part of the National Survey on Drug Use and Health between 2002 and 2014. For each of the birth years between 1986 and 1996, we combined a series of nationally representative cross-sections to provide multi-year data strings designed to approximate nationally representative cohorts. Compared to youth born in the mid-to-late 1980s, youth born in the mid-1990s reported significantly higher levels of marijuana disapproval during the early adolescent years (Age 14: 1988=64.7%, 1994=70.4%) but lower levels of disapproval during the young adult years (Age 19: 1988=32.0%, 1994=25.0%; Age 20: 1988=27.9%, 1994=19.7%). Moreover, the prevalence of marijuana use among youth born in 1994 was significantly lower-compared to youth born in 1988-at age 14 (1988: 11.39%, 1994: 8.19%) and significantly higher at age 18 (1988: 29.67%, 1994: 34.83%). This pattern held even when adjusting for potential confounding by demographic changes in the population across the study period. We see evidence of changes in the perceptions of marijuana use among youth born during the late twentieth century. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Variation in egg size of the northern pintail

USGS Publications Warehouse

Flint, Paul L.; Grand, James B.

1996-01-01

Egg size is an important determinant of reproductive investment by birds. For many species, total investment in a clutch is limited by the size of stored reserves (Ankney and MacInnes 1978, Esler and Grand 1994a). Egg size determines the unit by which these stored reserves are partitioned. Individual females in most species of waterfowl show a high repeatability for egg size, implying that individual either cannot, or do not, alter their egg size in response to varying environmental conditions (batt and Prince 1979, Duncan 1987, Laurila and Hario 1988, Lessells et al 1989, Flint and Sedinger 1992). Thus differences in egg size appear to represent different reproductive strategies among individuals.Fitness can be measured by the number of offspring an individual contributes to a population. Egg size may be related to fitness in some species fo waterfowl as young from larger eggs are better able to survive extreme conditions (Ankney 1980, Thomas and Brown 1988). Birds laying larger clutches are almost always more fit as they fledge more young (Lessells 1986, Rockwell et al 1987, Flint 1993). These fitness patterns create the potential for a trade-off between clutch size and egg size where females laying large clutches of small eggs have the same fitness as females laying smaller clutches of large eggs. The fact that Northern Pintails (Anas acuta) utilize stored reserves (Mann and Sedinger 1993, esler and Grand 1994a) and have a high repeatability for egg size (i.e. egg size is fixed) (Duncan 1987), makes them candidates to engage in clutch size=egg size trade-offs (Rowher 1988, Rowher and Eisenhauer 1989). An inverse relationship between egg size and clutch size would be indicative of a phenotypic trade-off among these fitness components. Our goal in this study was to describe egg size variation in Northern Pintails (hereafter pintails) with regard to female age, body size, clutch size, year, initiation date, and nesting attempt. We compare our results to those from other populations of nesting pintails and discuss whether phenotypic clutch size-egg size tradeoffs exist for pintails.

The effects of increasing carbon dioxide (CO2) and climate on net carbon storage in terrestrial ecosystems of the conterminous United States for the period 1895-1993 were modeled with new, detailed historical climate information. For the period 1980-1993, results from an ensemble of three models agree within 25%, simulating a land carbon sink from CO2 and climate effects of 0.08 gigaton of carbon per year. The best estimates of the total sink from inventory data are about three times larger, suggesting that processes such as regrowth on abandoned agricultural land or in forests harvested before 1980 have effects as large as or larger than the direct effects of CO2 and climate. The modeled sink varies by about 100% from year to year as a result of climate variability.

[Factors related to the slowdown in the reduction of the tuberculosis incidence rate in Osaka City--structure of the high incidence rate of tuberculosis in Osaka City analyzed by administrative-ward group, five-year period and age group].

The tuberculosis incidence rate in Osaka City is the highest in Japan. We analyzed the incidence rate in Osaka City in five-year period from 1978 to 1997, namely, 1978-1982 (period I), 1983-1987 (period II), 1988-1992 (period III), and 1993-1997 (period IV). Until the first half of 1980, the tuberculosis incidence rate in Osaka City had been dropping every year, but the rate of decline has been slowed substantially or even stopped since 1983. The incidence rate ratio of Osaka City compared with the national rate was 2.0 to 2.3 from 1970 to 1975, but it has been increasing from 1983 and is now higher than 3. We divided 24 wards of Osaka City into five groups based on selected employment indicators of population 15 years of age and over of 1995 National Census. Group A consists of two wards characterized by extremely high unemployment rate, Group B of four wards by high unemployment rate and high rate of manufacturing workers, Group C of six wards by high rate of non-manufacturing workers (tertiary industry workers), Group D of five wards by high rate of manufacturing workers, and Group E of seven wards by residential areas. The incidence rate of Group A had been declining during periods I and II but started to rise after period III. The rates of Group B and C had been declining from period I to II but the decline slowed down substantially even for every age class in periods III and IV. The incidence rates of Groups D and E have been falling. The incidence rate of the 50-69 year-old age group has been increasing substantially. The proportion of newly registered patients in Group A to all patients of Osaka City increased from 25.2% in period I to 32.7% in period IV. The number of newly registered patients of the 40-69 age class in Group A accounted for 45.1% of that in Osaka City in period IV. The slowdown in the reduction of the tuberculosis incidence rate has occurred not in all, but in only a few wards and it is a typical phenomenon of the middle-aged in those wards. It would be worth investigating whether a substantial decline in the tuberculosis incidence rate in Osaka City cannot be achieved by means of uniform control measures for all wards. Intensified tuberculosis control measures should focus on patients in specific wards and age groups.

Trends in surface ozone over Europe, 1978-1990

1994-01-01

It has been suggested that surface ozone concentrations in rural areas of Europe have been increasing at a rate of 1 to 3 percent per year over the past two to three decades, presumably due to human influences (Feister and Warmbt, 1987; Bojkov, 1988; Penkett, 1989). Recently, we have analyzed surface ozone data from 20 European stations of differing character (remote, rural, suburban and urban) for a common period of 1978-1988 (Low et al., 1992). It was found that there were pronounced annual and seasonal variations in the linear trends in different areas, and there was no dominant region-wide trend. In spring and, most notably, summer, stations on the maritime fringe of the network generally exhibited negative trends whilst those located further into the continental interior exhibited positive trends. In winter, most of the stations in the network exhibited positive trends. Relatively few of these trends were statistically significant. This paper updates our earlier analysis by extending the data sets of the network up to the year 1990. The spatial variations in surface ozone trends over the extended period 1978-1990 are examined and discussed in comparison to the 1978-1988 patterns. The update confirms the overall conclusions of the earlier analysis, specifically that caution should be exercised in interpreting the results of trend analyses based on station data representative of a limited period of time and/or geographical area.

Hungry Horse Dam Fisheries Mitigation; Kokanee Stocking and Monitoring in Flathead Lake, 1996 Progress Report.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Carty, Daniel; Knoetek, W. Ladd

1997-06-01

Kokanee salmon Oncorhynchus nerka were introduced into Flathead Lake in 1916. The kokanee population declined in the 1960s and 1970s, and kokanee disappeared from Flathead Lake in the late 1980s. Their disappearance has been attributed to the long-term effects of the construction and operation of Hungry Horse and Kerr dams, excessive harvest by anglers, and changes in the lake food web induced by the introduction of opossum shrimp Mysis relicta. Attempts to reestablish kokanee in the Flathead Lake ecosystem between 1988 and 1991 were unsuccessful. In 1991, Montana Fish, Wildlife and Parks (MFWP) and the Confederated Salish and Kootenai Tribesmore » (CSKT) wrote a mitigation plan to restore kokanee to Flathead Lake. In 1993, MFWP, CSKT, and the U.S. Fish and Wildlife Service wrote a mitigation implementation plan that initiated a 5-year test program to use hatchery-reared fish to reintroduce kokanee to the lake. Stocking hatchery-reared kokanee into Flathead Lake began in 1993; the 5-year {open_quotes}kokanee test{close_quotes} started in 1994 and is scheduled to continue through 1998. The annual stocking objective is 1 million yearling kokanee (6-8 in long). Criteria used to evaluate the success of the 5-year test are (1) 30% survival of kokanee 1 year after stocking, (2) yearling-to-adult survival of 10%, and (3) annual harvest of 50,000 kokanee ({ge} 11 in) and fishing effort {ge} 100,000 angler hours.« less

Evidence on the impact of legislative changes on individual alcohol consumption is limited. Using an observational study design, we assessed trends in individual alcohol consumption of a Swiss adult population following the public policy changes that took place between 1993 and 2014, while considering individual characteristics and secular trends. Cross-sectional study. Swiss general adult population. Data from 18 963 participants were collected between 1993 and 2014 (aged 18-75 years). We used data from the 'Bus Santé' study, an annual health survey conducted in random samples of the adult population in the State of Geneva, Switzerland. Individual alcohol intake was assessed using a validated food frequency questionnaire. Individual characteristics including education were self-reported. 7 policy changes (6 about alcohol and 1 about tobacco) that occurred between 1993 and 2014 defined 6 different periods. We predicted alcohol intake using quantile regression with multivariate analysis for each period adjusting for participants' characteristics and tested significance periods. Sensitivity analysis was performed including drinkers only, the 10th centile of highest drinkers and smoker's status. Between 1993 and 2014, participants' individual alcohol intake decreased from 7.1 to 5.4 g/day (24% reduction, p<0.001). Men decreased their alcohol intake by 34% compared with 22% for women (p<0.001). The decrease in alcohol intake remained significant when considering drinkers only (28% decrease, p<0.001) and the 10th centile highest drinkers (24% decrease, p<0.001). Consumption of all alcoholic beverages decreased between 1993 and 2014 except for the moderate consumption of beer, which increased. After adjustment for participants' characteristics and secular trends, no independent association between alcohol legislative changes and individual alcohol intake was found. Between 1993 and 2014, alcohol consumption decreased in the Swiss adult population independently of policy changes. Published by the BMJ Publishing Group Limited.

We used geologic and geochemical techniques to document the change with time of the distribution and concentration of contaminated bottom sediments in southern Lake Champlain near an International Paper Company plant. Our work, initiated in 1972, was expanded on behalf of Vermont citizens in a class-action suit against the International Paper Company. To update our 1972-1973 results, we collected nine cores in 1988 upstream and downstream from the paper plant effluent diffuser. Water content, volatile solids, organic carbon, and three ratios, Al/Si, Cl/Si, and S/Si, in addition to megascopic and microscopic observations, were evaluated to identify and trace the distribution of effluent and to measure the thickness of sediment affected by or containing components of effluent. Analyses were carried out on samples from the cores as well as from effluent collected directly from the plant's waste treatment facility. In 1973, two years after the plant opened, we cored near the diffuser; sediment contaminated with effluent was 4.5 cm thick. In 1988, in the same area, sediment contaminated with effluent was 17 cm thick. In 15 years, water content increased from 72 to 85 percent, volatile solids from 7 to 20 percent, and organic carbon from 2 to 12 percent. Cl/Si and S/Si were high only near the diffuser and were zero elsewhere. In the area of the diffuser, contaminated sediment appears to be accumulating at a rate of about 1 cm/yr. At a control location 22 km upstream (south) from the plant, the top, poorly consoli-dated layer was only 1 cm or less thick both in 1973 and in 1988. The class-action suit was settled in favor of the plaintiffs for $5 million. ?? 1993 Springer-Verlag.

Changes in the treatment and outcomes of acute myocardial infarction in Quebec, 1988-1995

PubMed Central

Pilote, L; Lavoie, F; Ho, V; Eisenberg, M J

2000-01-01

BACKGROUND: Few studies have reported population-based information on the treatment trends and outcomes of patients who have had an acute myocardial infarction (AMI). We therefore examined patterns of care and outcomes for AMI patients in Quebec, Canada, between 1988 and 1995. METHODS: Longitudinal data files of hospital admissions in Quebec (Med-Echo database) and inpatient and outpatient services (Régie de l'Assurance Maladie du Québec database) were used to construct cohorts of all AMI patients in the province between 1988 and 1995. Temporal trends in the use of cardiac procedures after an AMI, discharge prescriptions and mortality rates were examined. RESULTS: Between 1988 and 1995 the age- and sex-adjusted rates of AMI in the Quebec population declined (148 per 100,000 in 1988 to 137 per 100,000 in 1995). The use of intensive cardiac procedures increased in the same period; the 1-year cumulative incidence rate of catheterization increased from 28% in 1988 to 31% in 1994, that of angioplasty rose from 8% to 15% and that of coronary artery bypass surgery from 6% to 8%. Prescriptions for ASA, beta-blockers, lipid-lowering agents and angiotensin-converting enzyme inhibitors increased, and prescriptions for nitrates and calcium antagonists decreased. These temporal changes were paralleled by a decrease in mortality rates post-AMI. All-cause 1-year cumulative incidence mortality rates decreased from 23% in 1988 to 19% in 1994. INTERPRETATION: The decrease in AMI-related mortality in Quebec between 1988 and 1995 may be linked to changes in treatment strategies (i.e., increased use of cardiac surgical procedures and medications shown to increase survival).

Garrett, R.G.; Bales, J.D.

1995-01-01

Treyburn is a 5,400 acre planned, mixed-use community located in the Falls Lake watershed in the upper Neuse River Basin of North Carolina. From February 1988 through 1993, hydrologic-data were collected at 17 study sites in or near the Treyburn development to compare the effects of varying types of land-use development on the water-quality of streams flowing in or near the development. The collected hydrologic data included measurements of streamflow and concentrations of major dissolved constituents, nutrients, minor elements, and organic compounds. Streamflow in the study basin was approximately 40 percent lower in 1992 and 40 percent higher in 1993 than the long-term annual mean of the long-term discharge records at Flat River in Bahama. Calcium and bicarbonate were the predominant cation and anion at all study sites except one. Mean total nitrogen and phosphorus concentrations at sites in the Treyburn development ranged from 0.5 to 0.8 and 0.03 to 0.10 milligrams per liter, respectively. Total aluminum, iron, and manganese were the metals most frequently detected in the 200 organic compunds analyzed. Dichloro- difluoromethane and methylene chloride were detected most often.

Objectives. Through a sister-university relationship between the University of Basrah and the University of Washington, we analyzed Ibn Ghazwan Hospital's leukemia registry data to evaluate trends in childhood leukemia since 1993. Methods. We documented leukemia cases among children aged 0 to 14 years for each of the last 15 years. Population data were obtained from a 1997 census and various subsequent estimates to calculate rates. Results. We observed 698 cases of childhood leukemia between 1993 and 2007, ranging between 15 cases (2.6 per 100 000 annual rate) in the first year and 56 cases (6.9 per 100 000 annual rate) in the final year, reaching a peak of 97 cases in 2006 (12.2 per 100 000 annual rate). Conclusions. Childhood leukemia rates in Basrah more than doubled over a 15-year period. The test for trend was significant (P = .03). Basrah's childhood leukemia rate compared unfavorably with neighboring Kuwait and nearby Oman, as well as the United States, the European Union, and other countries. PMID:20167894

Direct observation of crystal growth from solution using optical investigation of a growing crystal face

The first technical report for the period 1 Jan. 1993 till 31 Dec. 1993 for the research entitled, 'Direct observation of crystal growth from solution using Optical Investigation of a growing crystal Face' is presented. The work on the project did not start till 1 June 1993 due to the non-availability of the required personnel. The progress of the work during the period 1 June 1993 till the end of 1993 is described. Significant progress was made for testing various optical diagnostic techniques for monitoring crystal solution. Some of the techniques that are being tested are: heterodyne detection technique, in which changes in phase are measured as a interferometric function of time/crystal growth; a conventional technique, in which a fringe brightness is measured as a function of crystal growth/time; and a Mach-Zehnder interferometric technique in which a fringe brightness is measured as a function of time to obtain information on concentration changes. During the second year it will be decided to incorporate the best interferometric technique along with the ellipsometric technique, to obtain real time in-situ growth rate measurements. A laboratory mock-up of the first two techniques were made and tested.

Work in the area of mechano-caloric phenomena was initiated during 1988 with startup in the Summer 1988 period. The ideal system utilizing He-II super-phenomena is modeled readily, within the frame of thermodynamics energetics, using the concept of an ideal superleak. The real system however uses porous media of non-ideal pore-grain ingredients. The early phase of experimental and related modeling studies is outlined for the time period from Summer 1988 to the end of 1988.

Hydrology of prairie pothole wetlands during drought and deluge: A 17-year study of the Cottonwood Lake wetland complex in North Dakota in the perspective of longer term measured and proxy hydrological records

USGS Publications Warehouse

Winter, T.C.; Rosenberry, D.O.

1998-01-01

From 1988 to 1992 the north-central plains of North America had a drought that was followed by a wet period that continues to the present (1997). Data on the hydrology of the Cottonwood Lake area (CWLA) collected for nearly 10 years before, and during, the recent dry and wet periods indicate that some prairie pothole wetlands served only a recharge function under all climate conditions. Transpiration from groundwater around the perimeter of groundwater discharge wetlands drew water from the wetlands by the end of summer, even during very wet years. Long-term records of a climate index (Palmer Drought Severity Index), stream discharge (Pembina River), and lake level (Devils Lake) were used to put the 17-year CWLA record into a longer term perspective. In addition, proxy records of climate determined from fossils in the sediments of Devils Lake were also used. These data indicate that the drought of 1988-92 may have been the second worst of the 20th century, but that droughts of that magnitude, and worse, were common during the past 500 years. In contrast, the present wet period may be the wettest it has been during the past 130 years, or possibly the past 500 years.

Sickness absence with cash benefits from the sickness insurance gives an opportunity to be relieved from work without losing financial security. There are, however, downsides to taking sickness absence. Periods of sickness absence, even short ones, can increase the risk for future spells of sickness absence and unemployment. The sickness period may in itself have a detrimental effect on health. The aim of the study was to investigate if there is an association between exposure to sickness absence at a young age and later sickness absence, disability pension, death, unemployment and income from work. Our cohort consisted of all immigrants aged 21-25 years in Sweden in 1993 (N = 38 207) and a control group of native Swedes in the same age group (N = 225 977). We measured exposure to sickness absence in 1993 with a follow-up period of 15 years. We conducted separate analyses for men and women, and for immigrants and native Swedes. Exposure to ≥60 days of sickness absence in 1993 increased the risk of sickness absence [hazard ratio (HR) 1.6-11.4], unemployment (HR 1.1-1.2), disability pension (HR 1.2-5.3) and death (HR 1.2-3.5). The income from work, during the follow-up period, among individuals with spells of sick leave for ≥60 days in 1993 was around two-thirds of that of the working population who did not take sick leave. Individuals on sickness absence had an increased risk for work absence, death and lower future income. © The Author 2015.

Analysis of 20th century rainfall and streamflow to characterize drought and water resources in Puerto Rico

USGS Publications Warehouse

Larsen, M.C.

2000-01-01

During the period from 1990 to 1997, annual rainfall accumulation averaged 87% of normal at the 12 stations with the longest period of record in Puerto Rico, a Caribbean island with a 1999 population of 3.8 million. Streamflow in rivers supplying the La Plata and Loi??za reservoirs, the principal water supply of the San Juan metropolitan area, was at or below the 10th flow percentile for 27% to 50% of the time between December 1993 and May 1996. Diminished reservoir levels in 1994 and 1995 affected more than 1 million people in the San Juan metropolitan area. Water rationing was implemented during this period and significant agricultural losses, valued at $165 million, were recorded in 1994. The public endured a year of mandatory water rationing in which sections of the city had their water-distribution networks shut off for 24 to 36 hours on alternate days. During the winter and spring of 1997-1998, water was rationed to more than 200,000 people in northwestern Puerto Rico because water level in the Guajataca reservoir was well below normal for two years because of rainfall deficits. The drought period of 1993-1996 was comparable in magnitude to a drought in 1966-1968, but water rationing was more severe during the 1993-1996 period, indicating that water management issues such as demand, storage capacity, water production and losses, and per capita consumption are increasingly important as population and development in Puerto Rico expand.

Suicide is a leading cause of death among school-aged children younger than 12 years but little is known about the epidemiology of suicide in this age group. To describe trends in suicide among US children younger than 12 years by sociodemographic group and method of death. Period trend analysis of national mortality data on suicide in children aged 5 to 11 years in the United States from January 1, 1993, to December 31, 2012. Data were analyzed per 5-year periods, between 1993 to 1997 and 2008 to 2012. Number of suicide deaths and crude suicide rates. Period trends in rates of suicide were estimated using negative binomial regression incidence rate ratios (IRRs). The overall suicide rate among children aged 5 to 11 years remained stable between 1993 to 1997 and 2008 to 2012 (from 1.18 to 1.09 per 1 million; IRR = 0.96; 95% CI, 0.90-1.03). However, the suicide rate increased significantly in black children (from 1.36 to 2.54 per 1 million; IRR = 1.27; 95% CI, 1.11-1.45) and decreased in white children (from 1.14 to 0.77 per 1 million; IRR = 0.86; 95% CI, 0.79-0.94). The overall firearm suicide rate (IRR = 0.69; 95% CI, 0.57-0.85) and firearm suicide rate among white boys (IRR = 0.72; 95% CI, 0.59-0.88) decreased significantly during the study. The rate of suicide by hanging/suffocation increased significantly in black boys (IRR = 1.35; 95% CI, 1.14-1.61), although the overall change in suicide rates by hanging/suffocation or other suicide methods did not change during the study. The stable overall suicide rate in school-aged children in the United States during 20 years of study obscured a significant increase in suicide incidence in black children and a significant decrease in suicide incidence among white children. Findings highlight a potential racial disparity that warrants attention. Further studies are needed to monitor these emerging trends and identify risk, protective, and precipitating factors relevant to suicide prevention efforts in children younger than 12 years.

Product quality and timely delivery are two of the most important parameters in determining the success of a mask manufacturing facility. Because of the sensitivity of this data, very little was known about industry performance in these areas until an assessment was authored and presented at the 1993 BACUS Symposium by Larry Regis of Intel Corporation, Neil Paulsen of Intel Corporation, and James A. Reynolds of Reynolds Consulting. This data has been updated and will be published and presented at this year's BACUS Symposium. Contributor identities will again remain protected by utilizing Arthur Andersen & Company to compile the submittals. Participation was consistent with last year's representation of over 75% of the total merchant and captive mask volume in the United States. The data compiled includes shipments, customer return rate, customer return reasons from 1988 through Q2, 1994, performance to schedule, plate survival yield, and throughput time (TPT).

Using age of colonizing douglas-fir for the dating of young geomorphic surfaces: a case study

Pierson, Thomas C.

2013-01-01

Dating of many types of young (<500 year), dynamic, geomorphic landforms (e.g. mass-movement erosional tracks and deposits, alluvial terraces, flood plains, etc.) for purposes of hazard assessment and mitigation commonly requires greater dating precision than is available through radiocarbon dating or other methods. Ages of trees growing on landform surfaces have been used in a number of studies to estimate the time of landform creation or surface clearing, but the time lag between surface formation or disturbance and the reestablishment of trees can vary from 1 to more than 200 years (Desloges and Ryder 1990; Frenzen et al. 1988, 2005; Larsen and Bliss 1998; McCarthy and Luckman 1993; Sigafoos and Hendricks 1969; Winter et al. 2002). Appropriate lag times for selected tree species and for particular climatic and altitudinal ranges must be determined for the method to be useful.

Effects of streamflows on stream-channel morphology in the eastern Niobrara National Scenic River, Nebraska, 1988–2010

Changes in channel metrics generally corresponded to changes in streamflow conditions, but other than changes in incipient flood-plain area, these changes were small and were not measured in all three segments simultaneously. Increases in total channel width (except in segment 1) and incipient flood-plain area between 1993 and 1999 corresponded to increases in streamflow. Channel narrowing (except in segment 1) between 1999 and 2003 corresponded to lower summer streamflows and extended durations of very low summer streamflow. Although the pattern of low summer streamflow and extended durations of very low summer streamflow continued during the 2004–6 period and at the beginning of the 2007–10 period, no further narrowing was measured. Consistent tributary summer inflows help to explain the resistance of segments 2 and 3 to further narrowing. Because segment 1 is already much narrower than segments 2 and 3, its average current velocity is likely to be swifter and, therefore, competent to offset further effects of the processes that led to its narrowness.

We assessed the incidence of infants born small-for-gestational-age (SGA) and large-for-gestational-age (LGA) in an Italian cohort over 20 years (1993-2013). Furthermore, we investigated maternal factors associated with SGA and LGA births. A retrospective review of obstetric records was performed on infants born in Chieti (Italy) covering every 5(th) year over a 20-year period, specifically examining data for 1993, 1998, 2003, 2008, and 2013. Infants with birthweight <10(th) percentile were defined as SGA, and those with birthweight >90(th) percentile as LGA. Data collected included newborn anthropometry, birth (multiple vs singleton), maternal anthropometry, previous miscarriage, gestational diabetes, hypertension, and smoking during pregnancy. There were a pooled total of 5896 live births recorded across the 5 selected years. The number of SGA (+60.6 %) and LGA (+90.2 %) births increased considerably between 1993 and 2013. However, there were no marked changes in the incidence of SGA or LGA births (8.3 % and 10.8 % in 1993 versus 7.6 % and 11.7 % in 2013, respectively). Maternal factors associated with increased risk of SGA infants included hypertension, smoking, and previous miscarriage (all p < 0.05), while greater pre-pregnancy BMI and gestational diabetes were risk factors for LGA births (all p < 0.05). There was an increase in the number of SGA and LGA births in Chieti over the last two decades, but there was little change in incidence over time. Most maternal factors associated with increased odds of SGA and LGA births were modifiable, thus incidence could be reduced by targeted interventions.

From 1988 to 1993, 30 cases of poliomyelitis associated with poliovirus type 2 were found in seven governorates of Egypt. Because many of the cases were geographically and temporally clustered and because the case isolates differed antigenically from the vaccine strain, it was initially assumed that the cases signaled the continued circulation of wild type 2 poliovirus. However, comparison of sequences encoding the major capsid protein, VP1 (903 nucleotides), revealed that the isolates were related (93 to 97% nucleotide sequence identity) to the Sabin type 2 oral poliovirus vaccine (OPV) strain and unrelated (<82% nucleotide sequence identity) to the wild type 2 polioviruses previously indigenous to Egypt (last known isolate: 1979) or to any contemporary wild type 2 polioviruses found elsewhere. The rate and pattern of VP1 divergence among the circulating vaccine-derived poliovirus (cVDPV) isolates suggested that all lineages were derived from a single OPV infection that occurred around 1983 and that progeny from the initiating infection circulated for approximately a decade within Egypt along several independent chains of transmission. Complete genomic sequences of an early (1988) and a late (1993) cVDPV isolate revealed that their 5′ untranslated region (5′ UTR) and noncapsid- 3′ UTR sequences were derived from other species C enteroviruses. Circulation of type 2 cVDPVs occurred at a time of low OPV coverage in the affected communities and ceased when OPV coverage rates increased. The potential for cVDPVs to circulate in populations with low immunity to poliovirus has important implications for current and future strategies to eradicate polio worldwide. PMID:12857906

The importance of pelvic lymphadenectomy (LND) for diagnostic and therapeutic purposes at the time of radical cystectomy (RC) for bladder cancer is well documented. Although some debate remains on the optimal number of lymph nodes removed, 10 nodes has been proposed as constituting an adequate LND. We used data from the Surveillance, Epidemiology, and End Results database to examine predictors and temporal trends in the receipt of an adequate LND at the time of RC for bladder cancer. Within the Surveillance, Epidemiology, and End Results database, we extracted data on all patients with nonmetastatic bladder cancer receiving RC in the years 1988 to 2010. First, we assess the proportion of individuals undergoing RC who received an adequate LND (≥10 nodes removed) over time. Second, we calculate odds ratios (ORs) of receiving an adequate LND using logistic regression modeling to compare study periods. Covariates included sex, race, age, region, tumor stage, urban vs. rural location, and insurance status. Among the 5,696 individuals receiving RC during the years 1988 to 2010, 2,576 (45.2%) received an adequate LND. Over the study period, the proportion of individuals receiving an adequate LND increased from 26.4% to 61.3%. The odds of receiving an adequate LND increased over the study period; a patient undergoing RC in 2008 to 2010 was over 4-fold more likely to receive an adequate LND relative to a patient treated in 1988 to 1991 (OR = 4.63, 95% CI: 3.32-6.45). In addition to time of surgery, tumor stage had a positive association with receipt of adequate LND (OR = 1.49 for stage IV [T4 N1 or N0] vs. stage I [T1 or Tis], 95% CI: 1.22-1.82). Age, sex, marital status, and race were not significant predictors of adequate LND. Adequacy of pelvic LND remains an important measure of surgical quality in bladder cancer. Our data show that over the years 1988 to 2010, the likelihood of receiving an adequate LND has increased substantially; however, a substantial minority of patients still does not receive LND. Further study into factors leading to adequate LND is needed to increase the use of this important technique. Copyright © 2015 Elsevier Inc. All rights reserved.

The Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) operated a grain storage facility in Waverly, Nebraska, from 1952 to 1974. During this time, the grain fumigant '80/20' (carbon tetrachloride/carbon disulfide) was used to preserve stored grain. In 1982, sampling by the U.S. Environmental Protection Agency (EPA) found carbon tetrachloride contamination in the town's groundwater. After an investigation of the contaminant distribution, the site was placed on the National Priority List (NPL) in 1986, and the CCC/USDA accepted responsibility for the contamination. An Interagency Compliance Agreement between the EPA and the CCC/USDA was finalized in May 1988 (EPAmore » 1990). The EPA (Woodward-Clyde Consultants, contractor) started immediate cleanup efforts in 1987 with the installation of an air stripper, a soil vapor extraction system, a groundwater extraction well, and groundwater and soil gas monitoring wells (Woodward-Clyde 1986, 1988a,b). After the EPA issued its Record of Decision (ROD; EPA 1990), the CCC/USDA (Argonne National Laboratory, contractor) took over operation of the treatment systems. The CCC/USDA conducted a site investigation (Argonne 1991, 1992a,b), during which a carbon tetrachloride plume in groundwater was discovered northeast of the former facility. This plume was not being captured by the existing groundwater extraction system. The remediation system was modified in 1994 (Argonne 1993) with the installation of a second groundwater extraction well to contain the contamination further. Subsequently, a detailed evaluation of the system resulted in a recommendation to pump only the second well to conserve water in the aquifer (Argonne 1995). Sampling and analysis after implementation of this recommendation showed continued decreases in the extent and concentrations of the contamination with only one well pumping (Argonne 1999). The CCC/USDA issued quarterly monitoring reports from 1988 to 2009. Complete documentation of the CCC/USDA characterization and remediation efforts, including the quarterly monitoring reports, is on the compact disc inside the back cover of this report. The EPA reported on the progress of the remediation systems in a series of five-year reviews (EPA 1993, 1999, 2004, 2009). These reports and other EPA documentation are also on the compact disc inside the back cover of this report, along with the Woodward-Clyde (1986, 1988a,b) documentation cited. Starting in 2006, the analytical results for groundwater (the only medium still being monitored) showed no carbon tetrachloride concentrations above the maximum contaminant level (MCL) of 5.0 g/L. Because the cleanup goals specified in the ROD (EPA 1990) had been met, the EPA removed the site from the NPL in November 2006 (Appendix A). In 2008 the National Pollutant Discharge Elimination System (NPDES) permit for the remediation system was deactivated, and a year later the EPA released its fourth and final five-year report (EPA 2009), indicating that no further action was required for the site and that the site was ready for unlimited use. In 2011-2012, the CCC/USDA decommissioned the remediation systems at Waverly. This report documents the decommission process and closure of the site.« less

Report of the Defense Science Board Task Force on National Aero-Space Plane (NASP) Program

NASA Technical Reports Server (NTRS)

1992-01-01

Six years ago, the Defense Science Board (DSB) initiated a review of the concept, technical basis, program content, and missions of the National Aerospace Plane (NASP) program. The report was completed in Sep. 1988, and the recommendations contributed to strengthening the technical efforts in the NASP program. Since then, substantial technological progress has been made in the technology development phase (Phase 2) of the program. Phase 2 of the program is currently scheduled to end in late Fiscal Year 1993, with a decision whether to proceed to the experimental flight vehicle phase (Phase 3) to be made at that time. This decision will be a very significant one for the Department of Defense (DoD) and the National Aeronautics and Space Administration (NASA). In February of this year, the DSB was chartered to revisit the NASP program to assess the degree to which the many technical challenges of the program have been resolved, or are likely to be resolved by the end of Phase 2.

Improving cancer prevention at the worksite: how are Belgian companies dealing with smoking regulations?

Little is known about the impact of smoking policy on companies' policies related to smoking in Belgium. The study was designed in order to compare the companies' policies related to smoking (CPRS) in 1990 and in 1993. During this 3 year period, numerous information and regulation inputs (media, brochures) were aimed at companies to regulate smoking behavior in the workplace, so as to reduce the risks of passive smoking. A short questionnaire was mailed to 3543 Belgian companies in October 1990 and in June 1993 to assess: designation of smoke free areas (SFA); willingness to offer a worksite information program (WIP); willingness to offer a worksite smoking cessation program (WSCP); willingness to subsidize a WSCP; willingness to offer a WSCP during working hours; willingness to offer a meeting room for a WSCP and actual organization of a WSCP. In 1990, 773 companies (22%) and in 1993, 890 companies (25%) responded to the questionnaire. The results showed that small companies and companies with a high blue/white collar ratio were less able to implement health policy recommendations. A total of 325 (9%) companies responded to the 1990 and 1993 questionnaires. Comparison of 1990 and 1993 dataset showed that during this 3 year period, no major changes occurred for a majority of companies. Amongst the small positive changes, only the designation of smoke free areas and the organization of a small number of WSCP was observed. The conclusion is that despite inputs, little impact on smoking policies is noticeable. Strategies designed to intensify inputs and to promote implementation of regulation of WSCP should therefore further be studied.

The effects of higher cigarette prices on tar and nicotine consumption in a cohort of adult smokers.

2004-01-01

The objective of this paper is to estimate the demand for tar and nicotine in cigarettes as a function of cigarette prices in a cohort of cigarette 11,966 smokers followed for 5 years. Data for the analysis come from a longitudinal telephone survey of 11,966 smokers who were interviewed in 1988 and 1993 as part of the Community Intervention Trial for Smoking Cessation (COMMIT). Separate models are estimated for three age groups to account for differences in levels of addiction and brand loyalty across age. We found that smokers respond to higher cigarette prices by reducing the number of cigarettes smoked per day but also by switching to cigarettes that are higher in tar and nicotine per cigarette.

We examined mortality time trends and premature mortality among individuals with and without schizophrenia over a 20-year period. In this population-based, repeated cross-sectional study, we identified all individual deaths that occurred in Ontario between 1993 and 2012 in persons aged 15 and over. We plotted overall and cause-specific age- and sex-standardized mortality rates (ASMRs), stratified all-cause ASMR trends by sociodemographic characteristics, and analyzed premature mortality using years of potential life lost. Additionally, we calculated mortality rate ratios (MRRs) using negative binomial regression with adjustment for age, sex, income, rurality and year of death. We identified 31 349 deaths among persons with schizophrenia, and 1 589 902 deaths among those without schizophrenia. Mortality rates among people with schizophrenia were 3 times higher than among those without schizophrenia (adjusted MRR 3.12, 95% confidence interval 3.06-3.17). All-cause ASMRs in both groups declined in parallel over the study period, by about 35%, and were higher for men, for those with low income and for rural dwellers. The absolute ASMR difference also declined throughout the study period (from 16.15 to 10.49 deaths per 1000 persons). Cause-specific ASMRs were greater among those with schizophrenia, with circulatory conditions accounting for most deaths between 1993 and 2012, whereas neoplasms became the leading cause of death for those without schizophrenia after 2005. Individuals with schizophrenia also died, on average, 8 years younger than those without schizophrenia, losing more potential years of life. Although mortality rates among people with schizophrenia have declined over the past 2 decades, specialized approaches may be required to close the persistent 3-fold relative mortality gap with the general population. © 2017 Canadian Medical Association or its licensors.

Development in the Chesapeake Bay region has adversely affected the water quality of the Bay. The general degradation in the Bay has resulted in the decline of commercial fishing industries and has reduced the area of aquatic vegetation that provides food and habitat for fish and shellfish. In order to assess the effectiveness of programs aimed at reducing the effects of excess nutrients and suspended solids on Chesapeake Bay, it is necessary to quantify the loads of these constituents into the Bay, and to evaluate the trends in water quality. This report presents the results of a study funded by the Virginia Department of Environmental Quality-Chesapeake Bay and Coastal Programs and the U.S. Geological Survey, to monitor and estimate loads of selected nutrients and suspended solids discharged to Chesapeake Bay from five major tributaries in Virginia. The water-quality data and load estimates provided in this report also will be used to calibrate computer models of Chesapeake Bay. Water-quality constituents were monitored in the James and Rappahannock Rivers over a 5-year period, and in the Pamunkey, Appomattox, and Mattaponi Rivers over a 4-year period. Water-quality samples were collected from July 1, 1988 through June 30, 1993, for the James and Rappahannock Rivers; from July 1, 1989 through June 30, 1993, for the Pamunkey and Appomattox Rivers; and from September 1, 1989 through June 30, 1993, for the Mattaponi River. Water-quality samples were collected on a scheduled basis and during stormflow to cover a range in discharge conditions. Monitored water-quality constituents, for which loads were estimated include total suspended solids (residue, total at 105 Celsius), dissolved nitrite-plus-nitrate nitrogen, dissolved ammonia nitrogen, total Kjeldahl nitrogen, total nitrogen, total phosphorus, dissolved orthophosphorus, total organic carbon, and dissolved silica. Organic nitrogen concentrations were calculated from measurements of ammonia and total Kjeldahl nitrogen, and organic nitrogen loads were estimated using these calculations. Other selected water-quality constituents were monitored for which loads were not calculated. Daily mean load estimates of each constituent were computed by use of a seven-parameter log-linear-regression model that uses variables of time, discharge, and seasonality. Concentration of total nitrogen ranged from less than 0.14 to 3.41 mg/L (milligrams per liter), with both extreme values occurring at the Rappahannock River. Concentration of total Kjeldahl nitrogen ranged from less than 0.1 mg/L in the James, Rappahannock, and Appomattox Rivers to 3.0 mg/L in the James River. Organic nitrogen was the predominant form of nitrogen at all stations except the Rappahannock River, where nitrite-plus-nitrate nitrogen was predominant, and organic nitrogen comprised the majority of the measured total Kjeldahl nitrogen at all stations, ranging from 0.01 mg/L in the Appomattox River to 2.86 mg/L in the James River. Concentration of dissolved ammonia nitrogen ranged from 0.01 mg/L in the Pamunkey River to 0.54 mg/L at the James River. Concentration of nitrite-plus-nitrate nitrogen ranged from 0.02 to 1.05 mg/L in the James River. Concentrations of total phosphorus ranged from less than 0.01 mg/L in the Rappahannock and the Mattaponi Rivers to 1.4 mg/L in the James River. Dissolved orthophosphorus ranged from less than 0.01 mg/L in all five rivers to 0.51 mg/L in the James River. Total suspended solids ranged from a concentration of less than 1 mg/L in all five rivers to 844 mg/L in the Rappahannock River. Total organic carbon ranged from 1.1 mg/L in the Appomattox River to 110 mg/L in the Rappahannock River. Dissolved silica ranged from 2.4 mg/L in the James River to 18 mg/L in the Appomattox River. The James and Rappahannock Rivers had high median concentrations and large ranges in concentrations for most constituents, probably because of a greater number of point and nonpoint sources of nutrients and suspend

Changing educational inequalities in India in the context of affirmative action.

Desai, Sonalde; Kulkarni, Veena

Indian society suffers from substantial inequalities in education, employment, and income based on caste and ethnicity. Compensatory or positive discrimination policies reserve 15% of the seats in institutions of higher education and state and central government jobs for people of the lowest caste, the Scheduled Caste; 7.5% of the seats are reserved for the Scheduled Tribe. These programs have been strengthened by improved enforcement and increased funding in the 1990s. This positive discrimination has also generated popular backlash and on-the-ground sabotage of the programs. This paper examines the changes in educational attainment between various social groups for a period of nearly 20 years to see whether educational inequalities have declined over time. We use data from a large national sample survey of over 100,000 households for each of the four survey years--1983, 1987-1988, 1993-1994, and 1999-2000--and focus on the educational attainment of children and young adults aged 6-29. Our results show a declining gap between dalits, adivasis, and others in the odds of completing primary school. Such improvement is not seen for Muslims, a minority group that does not benefit from affirmative action. We find little improvement in inequality at the college level. Further, we do not find evidence that upper-income groups, the so-called creamy layer of dalits and adivasis, disproportionately benefit from the affirmative action programs at the expense of their lower-income counterparts.

Rates of initiation of renal replacement therapy (RRT), use of home modalities of treatment and patient outcomes vary considerably between countries. This paper reports the methods and baseline characteristics of countries participating in the EVEREST study (n = 46), a global collaboration examining the association between medical and non-medical factors and RRT incidence, modality mix and survival. Numbers of incident and prevalent patients were collected for current (2003-05) and historic (1983-85, 1988-90, 1993-95 and 1998-2000) periods stratified, where available, by age, gender, treatment modality and cause of end stage renal disease (diabetic versus non-diabetic). General population age and health indicators and national-level macroeconomic data were collected from secondary data sources. National experts provided primary data on renal service funding, resources and organization. The median (inter quartile range) RRT incidence per million of the population (pmp) was 130 pmp (102-167 pmp). The general population life expectancy at 60 was 22.1 years (19.7-23.1 years) and 6.9% had diabetes mellitus (5.4-9.0%). Healthcare spending as a percentage of gross domestic product was 8.1% (5.6-9.3%). Countries averaged nine dialysis facilities pmp (4-12 pmp), with 69.0% (43.9-99.0%) owned by the public or private not-for-profit sector. The number of nephrologists ranged from 0.5 to 48 pmp (median 12 pmp). The heterogeneity of EVEREST countries will enable modelling to examine the independent association between medical and non-medical factors on RRT epidemiology.

Assess longitudinal (10-y) changes in height, body weight and circumferences in elderly Europeans. Longitudinal assessments including baseline measurements taken in 1988/1989 which were repeated in 1993 (follow-up) and in 1999 (Finale). Longitudinal data were collected in nine European research towns: Hamme/Belgium (H/B), Roskilde/Denmark (R/DK), Haguenau/France (H/F), Romans/France (R/F), Padua/Italy (P/I), Culemborg/the Netherlands (C/NL), Vila Franca de Xira/Portugal (V/P), Betanzos/Spain (B/E), Yverdon/Switzerland (Y/CH). Using standardised methodologies data were collected from a random stratified sample of elderly men and women born between 1913 and 1918 including a total of 662 subjects in 1999. On average stature had decreased by 1,5-2 cm. Mean weight changed by -2.6 kg to - 4.2 kg in only three towns. An increase of at least 5 kg of body weight had taken place in 13 % of both men and women whereas 23 % of men and 27 % women had lost at least 5 kg of their baseline weight. Such weight loss over the first 4 years of follow-up was associated with higher mortality rates in men (crude RR 2.2, p<0.0001). Serial changes in arm circumference were small but waist circumference had increased by 3-4 cm. Whilst small-to-modest average changes in height, body weight and circumferences emerged over SENECA's 10-year follow-up period, considerable gains and losses of body weight had occurred in a significant proportion of the SENECA populations, whereby early weight loss might be predictive of subsequent survival.

Analysis of 20th century rainfall and streamflow to characterize drought and water resources in Puerto Rico

During the period from 1990 to 1997, annual rainfall accumulation averaged 87% of normal at the 12 stations with the longest period of record in Puerto Rico, a Caribbean island with a 1999 population of 3.8 million. Streamflow in rivers supplying the La Plata and Loíza reservoirs, the principal water supply of the San Juan metropolitan area, was at or below the 10th flow percentile for 27% to 50% of the time between December 1993 and May 1996. Diminished reservoir levels in 1994 and 1995 affected more than 1 million people in the San Juan metropolitan area. Water rationing was implemented during this period and significant agricultural losses, valued at $165 million, were recorded in 1994. The public endured a year of mandatory water rationing in which sections of the city had their water-distribution networks shut off for 24 to 36 hours on alternate days. During the winter and spring of 1997–1998, water was rationed to more than 200,000 people in northwestern Puerto Rico because water level in the Guajataca reservoir was well below normal for two years because of rainfall deficits. The drought period of 1993–1996 was comparable in magnitude to a drought in 1966–1968, but water rationing was more severe during the 1993–1996 period, indicating that water management issues such as demand, storage capacity, water production and losses, and per capita consumption are increasingly important as population and development in Puerto Rico expand.

Statistics on prevalence of pneumoconiosis among working underground coal miners based on epidemiologic data collected between 1960 and 1988 are presented. The main intent was to examine the time-related trend in prevalence, particularly after 1969, when substantially lower dust levels were mandated by federal act. Data from studies undertaken between 1960 and 1968 were collected and compared. Information for the period 1969 to 1988 was extracted from a large ongoing national epidemiologic study. Tenure-specific prevalence rates and summary statistics derived from the latter data for four consecutive time intervals within the 19-year period were calculated and compared. The results indicate a reduction in pneumoconiosis over time. The trend is similar to that seen in a large radiologic surveillance program of underground miners operated concurrently. Although such factors as x-ray reader variation, changes in x-ray standards, and worker self-selection for examination may have influenced the findings to some extent, adjusted summary rates reveal a reduction in prevalence concurrent with reductions in coal mine dust levels mandated by federal act in 1969.

Whooping cough is a communicable disease whose incidence has increased in recent years in some countries with vaccination. Since 1981, in Catalonia (Spain), cases must be reported to the Public Health Department. In 1997, surveillance changed from aggregated counts to individual report and the surveillance system was improved after 2002. Catalan public health is universal with equal coverage geographically. The aim of this study was to determine whether there are differences in whooping cough incidence in rural and urban counties. Cases in 1990-2010 were classified as rural or urban. Incidences and risk ratios (RR) between urban and rural counties and 95% CI were calculated. Associations between rural and urban counties and structural changes during the study period were analysed. Twelve years of the whole study period showed differences in incidence between rural and urban counties. The incidence was higher in urban counties in seven years and rural counties in five years. There was a positive association of whooping cough incidence in rural and urban counties in four-week periods. Structural changes were detected in the following four-week periods: 4th in 1993, 7th in 1996 and 3rd 2005 in rural counties and 5th 1993, 9th in 1996 and 8th in 2007 in urban counties. Differences in whooping cough between rural and urban counties were found. In most years, the incidence was higher in urban than in rural counties. Rural and urban counties show similar cyclic behaviour when four-week periods were considered.

The capability for capturing micrometeoroids intact through laboratory simulations [Tsou 1988] and in space [Tsou 1993] in passive underdense silica aerogel offers a valuable tool for cosmic dust research. The integrity of the sample handling medium can substantially modify the integrity of the sample. Intact capture is a violent hypervelocity event: the integrity of the capturing medium can cause even greater modification of the sample.

1993-01-01

The discovery of a coherent photometric modulation in Nova Oph 1988 with period 0.117515 +/- 0.000002 d, which is associated with the orbital period of the underlying binary, is reported. On the basis of photometric observations, it is concluded that Nova V2214 Oph 1988 is a magnetic nova with an orbital period inside the period gap. The inclusion of this system in the statistics of novae suggests that there is no period gap for novae and that there is a clear correlation between the occurrence of novae with short orbital periods and the presence of magnetic white dwarfs. It is suggested that funneling of the accretion flow onto the magnetic poles favors the conditions for a thermonuclear runaway, increasing the frequency of eruptions for magnetic systems.

An epidemiological study of inflammatory bowel disease in the Province of Granada, Spain, was conducted between 1979 and 1988. Altogether, 257 cases were identified: 167 ulcerative colitis, 79 Crohn's disease, and 11 indeterminate colitis. The mean incidence of ulcerative colitis in the 10 year period was 2/10(5) and 0.9/10(5) for Crohn's disease. This is the first epidemiological study in Spain of the incidence of ulcerative colitis and corroborates the results of an earlier population based study on the incidence of Crohn's disease in Spain.

Conservation reserve program: benefit for grassland birds in the northern plains

Reynolds, R.E.; Shaffer, T.L.; Sauer, J.R.; Peterjohn, B.G.

During the past few decades numbers of some species of upland-nesting birds in North America have declined. Duck species such as mallard (Anas platyrhynchos), northern pintail (A. acuta) and blue-winged teal (A. discors) have declined since the early 1970s and have remained low since 1985 (Caithamer et al. 1993). Some grassland-dependent nonwaterfowl species also have declined since 1966, as indicated by the North American Breeding Bird Survey (BBS) (Robbins et al. 1986). For prairie-nesting ducks, population declines can be attributed mostly to low recruitment, partially as a result of low nest success. Klett et al. (1988) concluded that nest success (probability of ≥1 egg of clutch hatches) in much of the U.S. Prairie Pothole Region was inadequate to maintain populations of the five most common upland-nesting duck species studied, and that predators were the most important cause of nest failure. Over the years, as grassland areas have been converted to cropland, ducks have concentrated their nesting in the remaining areas of available habitat, where predators such as red fox (Vulpes vulpes), striped skunk (Mephitis mephitis) and badger (Taxidea taxus) forage (Cowardin et al. 1983). The reasons for declining populations of grassland nonwaterfowl birds are not clear but the loss of suitable grassland-nesting habitat probably is an important factor. Currently, approximately 95 percent of the land in North Dakota is used for agricultural purposes, of which over 60 percent is used for annual crop production (Haugse 1990). Of the grassland that remains, 95 percent is used for livestock production. This probably had a severe impact on grassland bird species that seek idle grass cover for nesting. The 1985 and 1990 U.S. Farm Bills include provisions under the Food Security Act to fund a cropland-idling program called the Conservation Reserve Program (CRP). Over 36 million acres have been enrolled nationwide in the CRP since 1985 (Osborn 1993), and up to 25 percent of cropland in some counties has been converted primarily to grass. In North Dakota, nearly 3 million acres have been enrolled. Over 90 percent of the CRP plantings in North Dakota are grass and grass-legume mix composed primarily of wheatgrass (Agropyron spp.), smooth brome (Bromus inermis), alfalfa (Medicago saliva) and sweetclover (Melilotus spp.). Mixes of these species have been reported to attract high densities of nesting ducks (Duebbert and Kantrud 1974). According to the CRP provisions, the land must remain idle for the 10-year contract period, with the exception of emergency provisions for haying or grazing. CRP appears to have great potential for benefiting many species of grassland-nesting birds. There have been efforts to document the importance of the CRP to migratory birds in the Upper Great Plains of the U.S. Kantrud (1993) studied duck nest success in CRP cover and concluded that nest success was higher than in planted cover on U.S. Fish and Wildlife Service (FWS) Waterfowl Production Areas (WPAs). Johnson and Schwartz (1993a) measured the use of CRP fields by nonwaterfowl birds and reported that several species have responded positively by colonizing CRP fields. They concluded that CRP has the potential to help reverse the population declines of several species. We investigated the importance of CRP to upland-nesting ducks and certain other grassland-nesting birds. For ducks, we compared nest success in CRP cover with nest success in planted cover on WPAs in the same period (1992-93) and with that of an earlier period (1980-84). For nonwaterfowl, we used BBS data to compare the trends in populations of certain species found in CRP, for the periods 1966-86 (pre-CRP cover establishment) and 1987-92 (post-CRP cover establishment) in North Dakota.

This descriptive study evaluated behavioral and social science research on sport for 1993 through 2008, examined the characteristics of sport research, and identified mainstream issues appearing during these 16 years. Based on the Social Science Citation Index (SSCI) database from 1993 to 2008, 7,655 articles referring to sport or sports were available. The publication analyses showed that 13 core journals published the most articles in the behavioral sciences of sport. By analyzing all titles, author keywords, and KeyWords Plus, the results showed that physical education, athlete performance, and sports participation were the mainstream issues of sport research in the 16-year study period. The words adolescent, youth, and children frequently appeared, indicating that the emphasis of sport research focused on these participant groups. This bibliometric study reviewed global sports research in SSCI, and described certain patterns or trends in prior research on sport.

Strain, Laurel A; Grabusic, Carmen C; Searle, Mark S; Dunn, Nicole J

2002-04-01

This study examined changes in leisure activities of older adults over an 8-year period, and associated sociodemographic and health characteristics. Data were from a longitudinal study conducted in Winnipeg, Manitoba, Canada; 380 respondents were interviewed in-person in both 1985 and 1993. Changes in ten specific activities and the overall number of activities continued were examined. Theater/movies/spectator sports and travel were the activities least likely to be continued over the 8-year period; watching television and reading were most likely to be continued. Characteristics significantly related to changes in activities were age, gender, education, and self-rated health in 1985 as well as changes in marital status, self-rated health, and functional ability between 1985 and 1993, although no consistent pattern emerged. Leisure education is discussed as a means of introducing modifications to enhance older adults' participation in desired activities. Directions for future research are highlighted.

Under this contract SAIC has conducted research into the determination of coronal magnetic fields from vector magnetograms, including the development and application of algorithms to determine force-free coronal fields above selected observations of active regions. The contract began on June 30, 1992 and has a completion date of December 31, 1994. This contract is a continuation of work started in a previous contract, NASW-4571, which covered the period November 15, 1990 to December 14, 1991. During this second year we have concentrated on studying additional active regions and in using the estimated coronal magnetic fields to compare to coronal features inferred from observations.

Pricing and hedging derivative securities with neural networks: Bayesian regularization, early stopping, and bagging.

Gençay, R; Qi, M

We study the effectiveness of cross validation, Bayesian regularization, early stopping, and bagging to mitigate overfitting and improving generalization for pricing and hedging derivative securities with daily S&P 500 index daily call options from January 1988 to December 1993. Our results indicate that Bayesian regularization can generate significantly smaller pricing and delta-hedging errors than the baseline neural-network (NN) model and the Black-Scholes model for some years. While early stopping does not affect the pricing errors, it significantly reduces the hedging error (HE) in four of the six years we investigated. Although computationally most demanding, bagging seems to provide the most accurate pricing and delta hedging. Furthermore, the standard deviation of the MSPE of bagging is far less than that of the baseline model in all six years, and the standard deviation of the average HE of bagging is far less than that of the baseline model in five out of six years. We conclude that they be used at least in cases when no appropriate hints are available.

In 1988, the Iowa Department of Natural Resources, along with the University of Iowa conducted the Statewide Rural Well Water Survey, commonly known as SWRL. A total of 686 private rural drinking water wells was selected by use of a probability sample and tested for pesticides and nitrates. Sixty-eight of these wells, the '10% repeat' wells, were additionally sampled in October, 1990 and June, 1991. Starting in November, 1991, the University of Iowa, with sponsorship from the United States Environmental Protection Agency, revisited these wells to begin a study of the temporal variability of atrazine and nitrates in wells. Other wells, which had originally tested positive for atrazine in SWRL but were not in the 10% repeat population, were added to the study population. Temporal sampling for a year-long period began in February of 1992 and concluded in January of 1993. All wells were sampled monthly, one subset was sampled weekly, and a second subset was sampled for 14-day consecutive periods. Two unique aspects of this study were the use of an immunoassay technique to screen for triazines before gas chromatography/mass spectrometry (GC/MS) analysis and quantification of atrazine, and the use of well owners to sample the wells. A total of 1771 samples from 83 wells are in the final data base for this study. This paper reviews the study design, the analytical methodologies, and development of the data base. A companion paper discusses the analysis of the data from this survey.

The objective was to describe the epidemiology of emergency department (ED) visits for attempted suicide and self-inflicted injury over a 16-year period. Data were obtained from the National Hospital Ambulatory Medical Care Survey including all visits for attempted suicide and self-inflicted injury (E950-E959) during 1993-2008. Over the 16-year period, there was an average of 420,000 annual ED visits for attempted suicide and self-inflicted injury [1.50 (95% confidence interval, 1.33-1.67) visits per 1000 US population], and the average annual number for these ED visits more than doubled from 244,000 in 1993-1996 to 538,000 in 2005-2008. During the same time frame, ED visits for these injuries per 1000 US population almost doubled for males (0.84 to 1.62), females (1.04 to 1.96), whites (0.94 to 1.82) and blacks (1.14 to 2.10). Visits were most common among ages 15-19, and the number of visits coded as urgent/emergent decreased from 0.95 in 1993-1996 to 0.70 in 2005-2008. ED visit volume for attempted suicide and self-inflicted injury has increased over the past two decades in all major demographic groups. Awareness of these longitudinal trends may assist efforts to increase research on suicide prevention. In addition, this information may be used to inform current suicide and self-injury related ED interventions and treatment programs. Copyright © 2012 Elsevier Inc. All rights reserved.

Microphysical Model Studies of Venus Clouds

2004-11-01

We have adapted a standard cloud microphysics model to construct a self-consistent microphysical model of Venus' cloud layer which reproduces and extends previous studies (e.g. James et al. 1997). Our model is based on the Community Aerosol and Radiation Model Atmosphere (CARMA), which is a widely used computer code for terrestrial cloud microphysics, derived from the work of Toon et al. (1988). The standard code has been adapted to treat H2O and H2SO4 as co-condensing vapor species onto aqueous H2SO4 cloud droplets, as well as the nucleation of condensation nuclei to droplets. Vapor condensation and evaporation follows the method of James et al. (1997). Microphysical processes included in this model include nucleation of condensation nuclei, condensation and evaporation of H2O and H2SO4 vapor, and droplet coagulation. Vertical transport occurs though advection, eddy diffusion, sedimentation for both droplets and condensation nuclei. The cloud model is used to explore the sensitivity of Venus' cloud layer to environmental changes. Observations of the Venus' lower cloud from the Pioneer Venus, Venera, and Galileo spacecraft have suggested that the properties of the lower cloud may be time-variable, and at times may be entirely absent (Carlson et al. 1993, Grinspoon et al. 1993, Esposito et al. 1997). Our model explores the dependence of such behavior on environment factors such as variations in water or SO2 abundance. We have also calculated the optical properties of the model atmosphere using both the conventional optical constants for H2SO4 (Palmer and Williams, 1975), and the new data of Tisdale et al. (1998).

Changing ethnic disparity in ischemic stroke mortality in US children after the STOP trial.

PubMed

Lehman, Laura L; Fullerton, Heather J

2013-08-01

A prior report showed higher stroke mortality in US black children compared with white children (1979-1998), a disparity likely due in part to sickle cell disease, which leads to a high risk of childhood ischemic stroke. We hypothesized that this disparity has diminished since the publication of the Stroke Prevention Trial in Sickle Cell Anemia (STOP trial) in 1998 demonstrating the efficacy of long-term blood transfusions for primary stroke prevention. To evaluate the demographics and secular trends in mortality from ischemic and hemorrhagic stroke (as a primary cause of death) in US children (<20 years) and determine if there has been a decrease in the disparity between white and black children since the publication of the STOP trial in 1998. We used death certificate data from the National Center for Health Statistics, 1988 through 2007. United States. Children who died in 1988 through 2007 in the United States. Publication of the STOP trial. Incidence rate ratios were calculated as the measure of relative risk. Among 1.6 billion person-years of US children (1988-2007), there were 4425 deaths attributed to stroke, yielding an average of 221 deaths per year; 20% were ischemic; 67%, hemorrhagic; and 12%, unspecified. The relative risk of ischemic stroke mortality for black vs white children dropped from 1.74 from 1988 through 1997 to 1.27 from 1998 through 2007. The ethnic disparity in hemorrhagic stroke mortality, however, remained relatively stable between these 2 periods: black vs white relative risk, 1.90 (1988-1997) and 1.97 (1998-2007). The excess risk of death from ischemic, but not hemorrhagic, stroke in US black children has decreased over the past decade. This may be related to the implementation of an effective ischemic stroke prevention strategy for children with sickle cell disease.

Trends in atmospheric ammonium concentrations in relation to atmospheric sulfate and local agriculture.

Ammonium (NH(4)(+)) concentrations in air and precipitation at the Institute of Ecosystem Studies (IES) in southeastern New York, USA declined over an 11-year period from 1988 to 1999, but increased from 1999 to 2001. These trends in particulate NH(4)(+) correlated well with trends in particulate SO(4)(2-) over the 1988-2001 period. The NH(4)(+) trends were not as well correlated with local cattle and milk production, which declined continuously throughout the period. This suggests that regional transport of SO(4)(2-) may have a greater impact on concentrations of NH(4)(+) and subsequent deposition than local agricultural emissions of NH(3). Ammonium concentrations in precipitation correlated significantly with precipitation SO(4)(2-) concentrations for the 1984-2001 period although NH(4)(+) in precipitation increased after 1999 and SO(4)(2-) in precipitation continued to decline after 1999. The correlation between NH(4)(+) and SO(4)(2-) was stronger for particulates than for precipitation. Particulate NH(4)(+) concentrations were also correlated with particulate SO(4)(2-) concentrations at 31 of 35 eastern U.S. CASTNet sites that had at least 10 years of data. Air concentrations of NH(4)(+) and SO(4)(2-) were more strongly correlated at the sites that were located within an agricultural landscape than in forested sites. At most of the sites there was either no trend or a decrease in NH(4)(+) dry deposition during the 1988-2001 period. The sites that showed an increasing trend in NH(4)(+) dry deposition were generally located in the southeastern U.S. The results of this study suggest that, in the northeastern U.S., air concentrations of NH(4)(+) and subsequent deposition may be more closely linked to SO(4)(2-) and thus SO(2) emissions than with NH(3) emissions. These results also suggest that reductions in S emissions have reduced NH(4)(+) transport to and NH(4)(+)-N deposition in the Northeast.

We describe temporal trends in stroke incidence stratified by age from our population-based stroke epidemiology study. We hypothesized that stroke incidence in younger adults (age 20-54) increased over time, most notably between 1999 and 2005. The Greater Cincinnati/Northern Kentucky region includes an estimated population of 1.3 million. Strokes were ascertained in the population between July 1, 1993, and June 30, 1994, and in calendar years 1999 and 2005. Age-, race-, and gender-specific incidence rates with 95 confidence intervals were calculated assuming a Poisson distribution. We tested for differences in age trends over time using a mixed-model approach, with appropriate link functions. The mean age at stroke significantly decreased from 71.2 years in 1993/1994 to 69.2 years in 2005 (p < 0.0001). The proportion of all strokes under age 55 increased from 12.9% in 1993/1994 to 18.6% in 2005. Regression modeling showed a significant change over time (p = 0.002), characterized as a shift to younger strokes in 2005 compared with earlier study periods. Stroke incidence rates in those 20-54 years of age were significantly increased in both black and white patients in 2005 compared to earlier periods. We found trends toward increasing stroke incidence at younger ages. This is of great public health significance because strokes in younger patients carry the potential for greater lifetime burden of disability and because some potential contributors identified for this trend are modifiable.

Leptospirosis in domestic animals in France: serological results from 1988 to 2007.

Leptospirosis is a common infection in domestic animals. The microscopic agglutination test (MAT) is used for serological diagnosis. From 1988 to 2007, the Leptospira Medical and Molecular Bacteriology Laboratory at the Nantes National College of Veterinary Medicine, Food Science and Engineering used the MAT to test serum samples from more than 40,000 cattle, 40,000 pigs, 20,000 horses and 9,500 dogs. Five Leptospira serogroups were prominent, with specific variations within the four animal species: Icterohaemorrhagiae, Australis, Sejroë, Grippotyphosa and Autumnalis. The prevalence and incidence of each serogroup varied for each species over the 20-year period: some serogroups were emergent during some years but disappeared later. This study reports the complex epidemiological features of leptospirosis. © OIE (World Organisation for Animal Health), 2016.

Professor Dr. Sci. Milan Djordjevitsh was an excellent cardiovascular surgeon and results of his professional and research work were well known to professional public in the country and over the world. He was born in Smederevska Palanka in 1933. He finished the University Schfool of Medicine in Belgrade in 1961 and specialized general surgery at the II Department of Surgery in Belgrade. His teacher, prof. dr. Vojislav Stojanovitsh, recognized his special interest for clinical and research work from the beginning. His doctor's thesis (1976) was "The Role of Veinous Valvula in Aortocoronographic Bypass During Increased Coronary Flow". In 1981 he formed a Bypass Centre of the Republic of Serbia which became later the Yugoslav European Reference Centre for pacemaker therapy. The same year (1981) he was rewarded "The October Award of the City of Belgrade" for science. He was the first to implant an implantable cardioverter defibrillator. This technique was carried out in Serbia only two months after the implantation of a similar system in Europe. Professor Djordjevitsh gave many lectures over the world: Detroit (1975), Huston (1975), Budapest (1978), Warsaw (1980), Stockholm (1982), Aman (1984), New-York (1988), Berlin (1987), Vienna (1998), Stockholm (1989), Moscow (1990). The professional and research work of professor Djordjevitsh in the field of electrostimulation of the heart was characterised by original ideas and permanent search for new possibilities, especially in the multidisciplinary field. Therefore, professor Djordjevitsh is considered to be the founder of modern clinical pacemaker therapy. He also practiced artistic and scientific photography. Since 1984 professor Djordjevitsh was member of the Nucleus of the European working group for heart electrostimulation and electrophysiology, and was elected in the presidency of the Nucleus; later he was its president. His interest was directed to the maturation of endocardial stimulation threshold; use of non-atrial sensors in the frequent adaptation of a permanent artificial conductor of cardiac rhythm-pacemaker to load; use of continuous electrostimulation of spinal cord in patients in terminal state of vasospastic and occlusive vascular diseases; study of the effort of electromagnetic fields on pacemaker inhibition and senzation; study of biologic-synthetic grafts. As a man of high standing, professor Djordjevitsh was expert for cardiovascular diseases and modern technology in the World Health Organization since 1988. On the basis of his great professional reputation in the country and abroad, professor Djordjevitsh was elected a corresponding member of the Serbian Academy of Science and Arts. After a few scientific meetings excellently organized by professor Djordjevitsh in the country (Dubrovnik, 1988 and in 1990 under the auspices of NASPE), professor Djordjevitsh had to organize a European congress on Pacemaker Therapy and Electrophysiology in Belgrade in 1993. Unfortunately, political events and early death of professor Djordjevitsh were the reasons why the congress was not held as planned. Professor Djordjevic died in Paris, but was buried in Belgrade in January 1993.

Twenty-three years (1993-2015) of homicide trends in the Transkei region of South Africa.

PubMed

Banwari, Meel

2018-01-01

Background Transkei is regarded as a rural part of South Africa. It was one of the black homelands where rigorous apartheid was practised. The incidence of firearm-related deaths used to be very high, but after the implementation of the Firearm Control Act in 2002, the trend changed. However, the murder rate is still a major public-health problem in this region of South Africa. Objective The aim of this study was to investigate 23 years (1993-2015) of homicide trends in the Transkei region of South Africa. Method A review of records of medico-legal autopsies performed at Mthatha Forensic Pathology Laboratory from 1993 to 2015 was undertaken. Results Between 1993 and 2015, the number of autopsies performed on people who had died unnatural deaths was 24,693. The records of 12,618 (51%) autopsies on victims of homicide between 1993 and 2015 were available for study. The average rate of murder was 85/100,000 of the population in this region. Of these deaths, on average 34/100,000 were caused by sharp-edged instruments, 30/100,000 by gunshot wounds and 21/100,000 by blunt trauma. The rate of murder of males was significantly higher than that of females, with a ratio of 5.7:1, and over the period of 23 years covered by this study, the incidence was highest (30.5/100,000) in the young age group between 21 and 30 years. Conclusion The rate of homicide is very high in the Transkei region of South Africa. It needs urgent intervention to curb unnecessary deaths.

Geographical differences in whooping cough in Catalonia, Spain, from 1990 to 2010

PubMed Central

2014-01-01

Background Whooping cough is a communicable disease whose incidence has increased in recent years in some countries with vaccination. Since 1981, in Catalonia (Spain), cases must be reported to the Public Health Department. In 1997, surveillance changed from aggregated counts to individual report and the surveillance system was improved after 2002. Catalan public health is universal with equal coverage geographically. The aim of this study was to determine whether there are differences in whooping cough incidence in rural and urban counties. Methods Cases in 1990–2010 were classified as rural or urban. Incidences and risk ratios (RR) between urban and rural counties and 95% CI were calculated. Associations between rural and urban counties and structural changes during the study period were analysed. Results Twelve years of the whole study period showed differences in incidence between rural and urban counties. The incidence was higher in urban counties in seven years and rural counties in five years. There was a positive association of whooping cough incidence in rural and urban counties in four-week periods. Structural changes were detected in the following four-week periods: 4th in 1993, 7th in 1996 and 3rd 2005 in rural counties and 5th 1993, 9th in 1996 and 8th in 2007 in urban counties. Conclusions Differences in whooping cough between rural and urban counties were found. In most years, the incidence was higher in urban than in rural counties. Rural and urban counties show similar cyclic behaviour when four-week periods were considered. PMID:24649975

Mass balance investigation of alpine glaciers through LANDSAT TM data

NASA Technical Reports Server (NTRS)

Bayr, Klaus J.

1989-01-01

An analysis of LANDSAT Thematic Mapper (TM) data of the Pasterze Glacier and the Kleines Fleisskees in the Austrian Alps was undertaken and compared with meteorological data of nearby weather stations. Alpine or valley glaciers can be used to study regional and worldwide climate changes. Alpine glaciers respond relatively fast to a warming or cooling trend in temperature through an advance or a retreat of the terminus. In addition, the mass balance of the glacier is being affected. Last year two TM scenes of the Pasterze Glacier of Aug. 1984 and Aug. 1986 were used to study the difference in reflectance. This year, in addition to the scenes from last year, one MSS scene of Aug. 1976 and a TM scene from 1988 were examined for both the Pasterze Glacier and the Kleines Fleisskees. During the overpass of the LANDSAT on 6 Aug. 1988 ground truthing on the Pasterze Glacier was undertaken. The results indicate that there was considerable more reflectance in 1976 and 1984 than in 1986 and 1988. The climatological data of the weather stations Sonnblick and Rudolfshuette were examined and compared with the results found through the LANDSAT data. There were relations between the meteorological and LANDSAT data: the average temperature over the last 100 years showed an increase of .4 C, the snowfall was declining during the same time period but the overall precipitation did not reveal any significant change over the same period. With the use of an interactive image analysis computer, the LANDSAT scenes were studied. The terminus of the Pasterze Glacier retreated 348 m and the terminus of the Kleines Fleisskees 121 m since 1965. This approach using LANDSAT MSS and TM digital data in conjunction with meteorological data can be effectively used to monitor regional and worldwide climate changes.

We analyzed 2 sets of data for Double-crested Cormorant (Phalacrocorax auritus) stomach contents (including esophageal contents) that were collected from April through June of 1986-1988 (N = 580) and 1992-1993 (N = 200) on the Penobscot River, Maine. Our objectives were to examine temporal and spatial variation in the spring diet and estimate the importance of Atlantic salmon (Salmo salar) smolts to the cormorant diet. We analyzed stomach contents relative to samples from 3 river sections: 5 mainstem dams collectively, above the head of tide, and free-flowing areas above and below the head of tide. Between years composition of taxa lists were compared (P = 0.05) relative to time and river section. We estimated taxon importance for data collected during 1992-1993 by ranking taxa according to 3 statistics: frequency of occurrence, mean percent volume, and numerical abundance. Data from 1986-88 were analyzed by frequency of occurrence only. Across the 3 river sections, the number of prey species recovered from cormorant stomachs increased from 15 in late April to at least 31 through May. Cormorants collected above the head of tide consumed 12 fish species (including freshwater, anadromous, and catadromous types), whereas birds collected below the head of tide consumed 28 freshwater and seasonally-available estuarine, marine benthic, and pelagic species. Salmon smolts were not recovered from stomachs collected in April, rare in stomach samples during the first week of June, and absent from the diet thereafter. In contrast, smolts were among the 5 most frequently occurring (1986-88) and highest ranking (1992-1993) prey taxa across the 3 river sections through May.

Risk behaviours and self rated health in Russia 1998

OBJECTIVES—As self rated health and mortality represent different dimensions of public health and as risk behaviours have been closely related to mortality, we wanted to examine whether (poor) self rated health on the one hand and risk behaviours on the other can be attributed to different causes.
METHODS—The Taganrog household survey (1998) was conducted in the form of face to face interviews and included 1009 people and their families. To estimate health differences and differences in risk behaviours between groups, logistic regressions were performed.
RESULTS—In Taganrog between 1993/94 and 1998, changes in self rated health seem to have been much more dramatic than changes in smoking and different in direction from changes in heavy alcohol consumption. Moreover, self rated "poor" health was especially common among those whose economic situation was worse in 1998 than 10 years before. However, having a poorer economy during the period 1988-1998, does not seem to have affected drinking or smoking habits significantly.
CONCLUSIONS—Self rated health seems to be closely related to three indicators of economic circumstances. Risk behaviours are probably important for the poor state of public health in Russia, but may be less sensitive to the economic aspects of the transition than is self rated health.

Open Access (OA) is a model for publishing scholarly peer reviewed journals, made possible by the Internet. The full text of OA journals and articles can be freely read, as the publishing is funded through means other than subscriptions. Empirical research concerning the quantitative development of OA publishing has so far consisted of scattered individual studies providing brief snapshots, using varying methods and data sources. This study adopts a systematic method for studying the development of OA journals from their beginnings in the early 1990s until 2009. Because no comprehensive index of OA articles exists, systematic manual data collection from journal web sites was conducted based on journal-level data extracted from the Directory of Open Access Journals (DOAJ). Due to the high number of journals registered in the DOAJ, almost 5000 at the time of the study, stratified random sampling was used. A separate sample of verified early pioneer OA journals was also studied. The results show a very rapid growth of OA publishing during the period 1993-2009. During the last year an estimated 191 000 articles were published in 4769 journals. Since the year 2000, the average annual growth rate has been 18% for the number of journals and 30% for the number of articles. This can be contrasted to the reported 3,5% yearly volume increase in journal publishing in general. In 2009 the share of articles in OA journals, of all peer reviewed journal articles, reached 7,7%. Overall, the results document a rapid growth in OA journal publishing over the last fifteen years. Based on the sampling results and qualitative data a division into three distinct periods is suggested: The Pioneering years (1993-1999), the Innovation years (2000-2004), and the Consolidation years (2005-2009).

In addition to the need to identify homicide trends among well-documented risk groups, this investigation was conducted to expand the limited existing knowledge about the risk of homicide according to educational attainment and among 2 growing ethnic groups, Hispanics and Asians. We examined the death certificates of the 69,621 persons who died of homicide in California from 1970 through 1993. Age, sex, race and ethnicity, and education level of the victim, along with the homicide method, were abstracted from each record. Frequencies, rates, and relative risk were calculated. Substantial increases in the homicide rates occurred for 15- to 19-year-olds (4.0-fold), men (1.9-fold), Hispanics (2.5-fold), and Asians or others (1.7-fold) from 1970 to 1993. The use of firearms consistently accounted for a growing proportion of all homicides, reaching a high in 1993 of 75% for all persons and 90% for 15- to 19-year-olds. High school dropouts have the highest homicide risk of all education groups. Homicide risk differentials by ethnicity, sex, and age all increased during the study period. Persons of color and youth have been disproportionately affected by homicide for many years, and these data indicate that things are getting worse. Redoubled collaborative prevention and intervention efforts are needed to reverse this trend. PMID:8909163

Effects of the application of highway deicing chemicals during winter months on ground- water quality are being studied by the U.S. Geological Survey in cooperation with the Ohio Department of Transportation and the Federal Highway Administration. Eight sites throughout the State were selected along major undivided highways where drainage is by open ditches and ground-water flow is approximately perpendicular to the highway. At these sites, records of deicer application rates are being kept and apparent movement of deicing chemicals through shallow, unconsolidated aquifers is being monitored by means of periodic measurements of specific con ductance and concentrations of dissolved sodium, calcium, and chloride. The counties and corre sponding sections of state routes being monitored are the following: State Route (SR) 3 in Ashland County, SR 84 in Ashtabula County, SR 29 in Champaign County, SR 4 in Clark County, SR 2 in Lucas County, SR 104 in Pickaway County, SR 14 in Portage County, and SR 97 in Richland County. The study began in January 1988 with background data collection, extensive literature review, and site selection. This process, including drilling of wells at the eight selected sites, lasted 3 years. Routine ground-water sampling at 4- to 6-week intervals began in January 1991. A relatively new type of multilevel, passive flow ground-water sampling device was constructed and used. Other conditions monitored on a regular basis included ground-water level (monitored con tinuously), specific conductance, air and soil temperature, precipitation, chloride concentration in soil samples, ground conductivity, and deicing chemical application times and rates. For the interim reporting period, water samples were collected from January 1991 through September 1993. Evidence from water analysis, specific conductance measurements, and surface geophysical measurements indicates that four of the eight sites (Ashtabula County, Lucas County, Portage County, and Richland County sites) are potentially affected by direct application of deic ing chemicals. Climatic data from the period January 1991 through September 1993 show that cold weather, and therefore deicing chemical application rates, varied widely across the State. As a consequence, only minor traces of dissolved chloride above background concentrations (mean, 12-25 mg/L) were determined in ground-water samples from the Pickaway County, Clark County, and Champaign County sites. At the Ashland and Richland County sites, dissolved chlo ride concentrations increased above background concentrations (from the upgradient well, pre sumably unaffected by road salt) only intermittently (mean background concentrations of 3-25 mg/L, rising to a mean of 49-77 mg/L). For the interim reporting period, the mean dissolved chloride concentration for all downgradient wells was about 2 times the background concentra tion (25mg/L) at the Ashland County site (50 mg/L) and 14 times the background concentration (3 mg/L) at the Richland County site (40 mg/L). At the Lucas County, Portage County, and Ash tabula County sites, deicing-chemical application was consistent throughout the winter, and downgradient dissolved chloride concentrations rarely returned to background concentrations (mean 6-32 mg/L) throughout the period. For the interim reporting period, the mean dissolved chloride concentration for all downgradient wells was about 3 times the background concentra tion at the Lucas County site (92 mg/L), 72 times the background concentration at the Portage County site (432 mg/L, 2 downgradient wells), and 21 times the background concentration at the Ashtabula County site (279 mg/L). Other factors that may affect the movement of deicing chemicals through the aquifer were examined, such as precipitation amounts; the types of subsurface materials; ground-water velocity and gradient; hydraulic conductivity; soil type; land use; and ODOT deicing priority. A final report is planned for 2001 afte

In recent years, the incidence of cervical cancer has been rising, particularly in young adults, as the second most common gynecological cancer in China. The aim of this study was to explore the incidence change and the epidemiological characteristics of cervical cancer in Beijing over the past 16 years. All the cases of the study were limited to Beijing residents diagnosed with cervical cancer and registered in Beijing from January 1, 1993, to December 31, 2008. A total of 4100 patients with cervical cancer were obtained from the Statistics Database of Beijing Cancer Registry (BJCaR). According to the registered data, we retrospectively reviewed all original cases which we can acquired in reported hospital. Cervical situ cancer, cervical metastatic cancer, non-Beijing residents and repeatedly registered cases were excluded. Totally, 3641 registered cases were verified correctly. Meanwhile, we also collected the following data: Age, occupation, detected methods, histological type, and staging. The trends of incidence and mortality were analyzed by Joinpoint Regression Program 4.1.1.1 produced by National Cancer Institute (NCI, USA). The annual percent change (APC) was calculated using the Joinpoint regression model. The crude rates of incidence and mortality were 10.4 and 1.0 per 100,000 women, respectively during 1993 to 2008. The average WHO age-standardized incidence rates were 11.5 per 100,000 women. There was a decrease in incidence annually by 8.0% (P = 0.3) during 1993-1996 and a rapid increase annually by 18.9% after 1999 (P < 0.01). The median age was 67 years in 1993, but the median age decreased to 45 years in 2008. The peak of the age-specific incidence curve was at 40 years in the most recent period (2005-2008), which was 25-30 years earlier than that in previous periods (1993-1996). In the 2224 cases, the numbers of patients with stage I, II, III and IV were 910 (40.9%), 601 (27%), 542 (24.4%), 171 (7.7%), respectively. The percentage of patients with stage I was 7.6% (13/171) in 1993-1996, but the percentage increased to 51.6% (643/1247) in 2005-2008 (P < 0.01). Otherwise the percentage of advanced stage (stage III-IV) during the same period was dropped down significantly from 52.0% (89/171) to 22.5% (280/1247) (P < 0.01). Unemployed and housewife ranked first accounting for 27.3% of the total (607/2224). Urban low-income people such as worker ranked the second accounting for 17.0% (377/2224), the third place was farmer accounting for 14.0% (312/2224). Only 381 (17.1%, 381/2224) women in 2224 were first detected cervical cancer by routine screenings. Company staff (36.5%, 139/381), professional and technical personnel (22.6%, 86/381), national official (22.0%, 84/381) occupied the top three (total 81.1%) in the 381 patients detected cervical cancer by screening. The cervical cancer incidence has showed a continuous rise in Beijing since 1999. Government-led mass screening should target the low socioeconomic population primarily. Meanwhile the government should enhance public health education of cancer screening to increase the rate of screening.

To assess the evolution of headaches in a workplace cohort over a 10-year period. Migraine headaches are associated with significant handicap in everyday activities and poor quality of life. The prevalence of migraine shows a bell-shaped age distribution with a peak during the third and fourth decades. However, there is little longitudinal data available on the natural history of this condition. A prospective health survey undertaken in a large workplace cohort since 1989 provides an opportunity to assess the evolution of migraine and other headache syndromes over a 10-year period. A sample of 2500 subjects who reported regular headaches was chosen at random from those with headache identified in a cohort of 46,244 employees of the French national power company aged between 35 and 50 years in 1989 participating in a yearly health survey. In 1993, all subjects were sent a headache questionnaire to complete and return. In 2003, an identical questionnaire was sent to all subjects who had returned exploitable data in 1993. Headache diagnosis was assigned retrospectively using the International Headache Society (IHS) criteria to migraine (IHS categories 1.1 and 1.2), migrainous disorder (IHS category 1.7), or other episodic headaches. Of 2500 subjects sampled, 2051 (82%) returned exploitable data for the first questionnaire in 1993. In 2003, 1250 (61%) of these provided a second data set. In 1993, 623 (30.4%) of subjects fulfilled diagnostic criteria for migraine. However, only 37% of these retained the diagnosis 10 years later. In contrast, the proportion of subjects with other forms of episodic headache rose from 23.7% to 31.6%. In 2003, 9.5% of the sample were headache-free. Retention or acquisition of a diagnosis of migraine was more common in women than in men, and age was associated with evolution to a less severe headache syndrome. In those subjects who continued to have headaches, frequency and severity were lower at the second assessment. Only a minority of subjects diagnosed with migraine or migrainous disorder retain the diagnosis 10 years later, with most subjects evolving to a less disabling headache type.

Populations, productivity, and feeding habits of seabirds at Cape Thompson, Alaska: Final report

Investigations of seabird population sizes and breeding biology were conducted at Cape Thompson from 1959 to 1961 during pre-development studies associated with the Atomic through 1982, the Alaskan Program (OCSEAP) supported determine whether changes Energy Commission’s “Project Chariot.” From 1976 Outer Continental Shelf Environmental Assessment efforts to recensus seabirds at Cape Thompson and had occurred since the 1959-61 period. Prior to the present study, it had been 6 years since the last efforts to census seabird colonies in this area.We established a field camp at the and occupied it continuously until 31 were selected for cliff nesting species comprising the Cape Thompson complex, mouth of Ikijaktusak Creek on 2 July August 1988. Permanent study plots in four of the five discrete colonies and regular observations were made throughout the study to document attendance patterns, breeding phenology, and success of murres and kittiwakes. Periodic collections of adults offshore were used to determine the food habits of study species. Shore-based work was supplemented with offshore studies of seabird foraging from the USFWS vessel Eagle-Tiglax, 24-31 August (Fig. 2).Correlation analysis revealed negative trends in murre attendance at all Cape Thompson colonies between 1960 and 1982 or 1988, significantly so for 3 of the 5 colonies. Based on apparent changes in species composition within the colonies, Common Murres declined at a more rapid rate than Thick-billed Murres between 1960 and 1988. Combining information from all colonies, it appears that murre populations have been relatively stable since about 1979. In contrast to murres, the kittiwake population showed no significant trends between 1960 and 1982 or between 1960 and 1988. All fluctuations in kittiwake numbers documented between years were within the variability expected within years. Breeding productivity of murres was about average during 1988 (0.47 young/pair), whereas the productivity of kittiwakes was very poor (0.15 young/pair).Murres and kittiwakes fed mostly on arctic cod and sand lance distributed widely but in low concentrations (e.g., 0.1-10 g/m3) UP to 1.20 km north and northwest of Cape Thompson. In the total area surveyed (225 km2), only two major feeding aggregations were observed where fish school densities exceeded 15 g/ins. Forage fish densities were higher in shallow Alaska Coastal Current waters than offshore in Bering Sea waters, and piscivorous seabirds like murres and kittiwakes fed mostly in coastal waters. Reduced numbers of fish in murre and kittiwake stomachs in August and low breeding success of kittiwakes suggested that forage fish densities observed around Cape Thompson in late August were sufficient to sustain murres but were insufficient for, or inaccessible to, kittiwakes.The breeding failure of Black-legged Kittiwakes at Cape Thompson in 1988 was part throughout causes of kittiwakes of a pervasive syndrome of failure in this species observed the Bering/Chukchi seas and Gulf of Alaska in recent years. The recurrent widespread breeding failure need to be identified if are to have a role in area-wide population monitoring during the period of Alaskan OCS development by the oil and gas industry.The system of land-based plots established in 1988 is recommended for future population monitoring of cliff-nesting birds at Cape Thompson. Based on the coefficients of variation among counts observed in this study, it is estimated that 10 replicate counts per year would detect an 8% change in numbers of Thick-billed Murres between years and a 12% change in Common Murres, with 75% certainty of statistical significance at the 0.05 level. Similarly, a 9% annual change in the population of Black-legged Kittiwakes should be detectable at the 0.05 significance level given samples of 10 replicate counts of the land-based plots.

Evolution of large amplitude Alfven waves in solar wind plasmas: Kinetic-fluid models

NASA Astrophysics Data System (ADS)

Nariyuki, Y.

2014-12-01

Large amplitude Alfven waves are ubiquitously observed in solar wind plasmas. Mjolhus(JPP, 1976) and Mio et al(JPSJ, 1976) found that nonlinear evolution of the uni-directional, parallel propagating Alfven waves can be described by the derivative nonlinear Schrodinger equation (DNLS). Later, the multi-dimensional extension (Mjolhus and Wyller, JPP, 1988; Passot and Sulem, POP, 1993; Gazol et al, POP, 1999) and ion kinetic modification (Mjolhus and Wyller, JPP, 1988; Spangler, POP, 1989; Medvedev and Diamond, POP, 1996; Nariyuki et al, POP, 2013) of DNLS have been reported. Recently, Nariyuki derived multi-dimensional DNLS from an expanding box model of the Hall-MHD system (Nariyuki, submitted). The set of equations including the nonlinear evolution of compressional wave modes (TDNLS) was derived by Hada(GRL, 1993). DNLS can be derived from TDNLS by rescaling of the variables (Mjolhus, Phys. Scr., 2006). Nariyuki and Hada(JPSJ, 2007) derived a kinetically modified TDNLS by using a simple Landau closure (Hammet and Perkins, PRL, 1990; Medvedev and Diamond, POP, 1996). In the present study, we revisit the ion kinetic modification of multi-dimensional TDNLS through more rigorous derivations, which is consistent with the past kinetic modification of DNLS. Although the original TDNLS was derived in the multi-dimensional form, the evolution of waves with finite propagation angles in TDNLS has not been paid much attention. Applicability of the resultant models to solar wind turbulence is discussed.

Near-Earth Asteroid Physical Observations: 1993-1995

In September 1993, we initiated a regular program of photometric observations of Near-Earth objects. Since that time we have been allocated 5-7 nights per month at the 42'' Hall telescope at Anderson Mesa. There are three goals of our observing program for each asteroid: (1) to obtain an accurate rotation period and characterization of the lightcurve, (2) to obtain the surface color, and (3) to measure the photometric parameters, H and G. All of the lightcurve observations are made in Kron-Cousins R and we always obtain a V-R color. Limited ECAS colors are also obtained when the objects are bright enough. We have secured periods for 9 asteroids, 1864 Daedalus, 1866 Sisyphus, 3200 Phaethon, 4954 Eric, 5693 (1993 EA), 5836 (1993 MF), 6489 (1991 JX), 1993 QP, and 1993 WD. Some of these periods are a confimation of an earlier result but most are new. We obtained colors for all these objects as well as four additional asteroids, 5407 (1992 AX), 1993 UC, 1993 VW, and 1994 LW. We have additional (as yet unreduced) observations of 2062 Aten, 2212 Hephaistos, 3752 Camillo, 5143 Heracles, 5863 (1983 RB), 6053 (1993 BW3), 7025 (1993 QA), 7092 (1992 LC), 1989 VA, 1992 TC, 1994 RC, and 1995 YA3. The fastest rotation period we find is 2.402 hours for 1866 Sisyphus and the slowest is 93QP at ~ 24 hours. The colors for these objects range from V-R=0.34 for 3200 Phaethon to V-R=0.49 for 1866 Sisyphus and 4954 Eric. Most colors fall near V-R=0.43. These observations should help to provide a more complete understanding of the surface properties and rotational states of the Near-Earth asteroids. This work was supported by NASA Grant NAGW-1470.

Over a two-year period beginning in March 2004, community colleges in Maryland developed a revised set of accountability indicators for a state-mandated Performance Accountability Report first required by a 1988 statute. A major innovation was a new model for assessing student degree progress. This article explains the development and components…

From EUCLID to Ptolemy in English Crop Circles

NASA Astrophysics Data System (ADS)

Hawkins, G. S.

1997-12-01

The late Lord Soli Zuckerman, science advisor to several British governments, encouraged the author, an astronomer, to test the theory that all crop circles were made by hoaxers. Within the hundreds of formations in Southern England he saw a thread of surprising historical content at the intellectual level of College Dons. One diagram in celestial mechanics involved triple conjunctions of Mercury, Venus and Mars every 67 2/3 years. Ptolemy's fourth musical scale, tense diatonic, occurred in the circles during the period 1978-88. Starting on E, Ptolemaic ratios make our perfect diatonic scale of white notes on the keyboard of the piano or church organ. For separated circles the ratio was given by diameters, and for concentric circles it was diameters squared. A series of rotationally symmetric figures began in 1988 which combined Ptolemy's ratios with Euclid's theorems. In his last plane theorem, Euclid (Elements 13,12) proved that the square on the side of an equilateral triangle is 3 times the square on the circum-circle radius -- diatonic note G(2). From the 1988 figure one can prove the square on the side is 16/3 times the square on the semi-altitude, giving note F(3). Later rotational figures over the next 5 years led to diatonic ratios for the hexagon, square and triangle. They gave with the exactness of Euclidean theorems the notes F, C(2) and E(2), and they are the only regular polygons to do so. Although these 4 crop theorems derive from Euclid, they were previously unknown as a set in the literature, nor had the Ptolemaic connection been published. Professional magazines asked the readers to provide a fifth theorem that would generate the above 4 theorems, but none was forthcoming. Ultimately the cicle makers showed knowledge of this generating theorem using a 200-ft design at Litchfield, Hampshire. After 1993, rotationally symmetric geometries continued to appear, but with much more complicated patterns. One design showed 6 crescent moons in a hexagon with cusps set on 2 concentric circles defining the note A(2). Here the mathematical level required application of Ptolemy's famous theorem of chords to confirm the A(2) ratio of exactly 10/3. The chords were the side of a hexagon joined to the side of a pentagon. We confirm Zuckerman's suggestion that there is a strong thread of expertise in the phenomenon worthy of scientific interest, and it spans a 20-year period. He asks: Why do they use a wheat field, and "how do they maintain their hidden identities?" Their type of knowledge rests in the past, and is not frequently found in the contemporary educational system.

To compare two population-based birth cohorts to assess trends in infant mortality rates and the distribution of relevant risk factors, and how these changed after an 11-year period. Data from two population-based prospective birth cohorts (1982 and 1993) were analyzed. Both studies included all children born in a hospital (> 99% of all births) in the city of Pelotas, Southern Brazil. Infant mortality was monitored through surveillance of all maternity hospitals, mortality registries and cemeteries. There were 5,914 live-born children in 1982 and 5,249 in 1993. The infant mortality rate decreased by 41%, from 36.0 per 1,000 live births in 1982 to 21.1 per 1,000 in 1993. Socioeconomic and maternal factors tended to become more favorable during the study period, but there were unfavorable changes in birthweight and gestational age. Poverty, high parity, low birthweight, preterm delivery, and intrauterine growth restriction were the main risk factors for infant mortality in both cohorts. The 41% reduction in infant mortality between 1982 and 1993 would have been even greater had the prevalence of risk factors remained constant during the period studied here. There were impressive declines in infant mortality which were not due to changes in the risk factors we studied. Because no reduction was seen in the large social inequalities documented in the 1982 cohort, it is likely that the reduction in infant mortality resulted largely from improvements in health care.

Rates of initiation of renal replacement therapy (RRT), use of home modalities of treatment and patient outcomes vary considerably between countries. This paper reports the methods and baseline characteristics of countries participating in the EVEREST study (n = 46), a global collaboration examining the association between medical and non-medical factors and RRT incidence, modality mix and survival. Numbers of incident and prevalent patients were collected for current (2003–05) and historic (1983–85, 1988–90, 1993–95 and 1998–2000) periods stratified, where available, by age, gender, treatment modality and cause of end stage renal disease (diabetic versus non-diabetic). General population age and health indicators and national-level macroeconomic data were collected from secondary data sources. National experts provided primary data on renal service funding, resources and organization. The median (inter quartile range) RRT incidence per million of the population (pmp) was 130 pmp (102–167 pmp). The general population life expectancy at 60 was 22.1 years (19.7–23.1 years) and 6.9% had diabetes mellitus (5.4–9.0%). Healthcare spending as a percentage of gross domestic product was 8.1% (5.6–9.3%). Countries averaged nine dialysis facilities pmp (4–12 pmp), with 69.0% (43.9–99.0%) owned by the public or private not-for-profit sector. The number of nephrologists ranged from 0.5 to 48 pmp (median 12 pmp). The heterogeneity of EVEREST countries will enable modelling to examine the independent association between medical and non-medical factors on RRT epidemiology. PMID:25949402

Continuous and periodic water-level measurements were made in 59 key wells throughout North Carolina. Additional measurements were made in 112 supplementary wells completed in Coastal Plain aquifers of the State. Changes in groundwater storage are shown in 3-year and 10-year hydrographs of selected wells in the State. The water table in the shallow aquifers was higher throughout most of 1989 and early 1990 than in 1988, indicating that these aquifers were sufficiently recharged by precipitation to replenish the late 1987-88 deficit in groundwater storage. Water levels in the heavily pumped Coastal Plain aquifers declined as a result of water being withdrawn from aquifer storage. Record low water levels were measured in 8 to 13 wells completed in the Castle Hayne aquifer and in 6 of 8 wells in the Peedee aquifer; the maximum annual declines during 1988-90 averaged 3.3 and 1.6 ft/yr, respectively, for these two aquifers. All wells in the Black Creek, upper Cape Fear, and lower Cape Fear aquifers had record low water levels during 1988-90, with maximum annual declines averaging 9.0, 2.2, and 2.6 ft/yr, respectively. Water levels in two of three wells in the Yorktown aquifer did not show a general downward trend during 1988-90, although water levels declined in the third well, reaching a record low in 1990. The effects of water withdrawals from major pumping centers in the North Carolina Coastal Plain are shown in potentiometric-surface maps of the Black Creek and lower Cape Fear aquifers.

Using a population-based register, this study sought to ascertain changes in the rate and severity of cerebral palsy (CP) in a geographically defined area of the UK among infants weighing less than 1500 g and born between 1984 and 1995. There were 417414 live births in the area, which included Berkshire, Buckinghamshire, Northamptonshire, and Oxfordshire. Of the 898 children with CP (526 males, 372 females), 194 (21.6%) weighed less than 1500 g at birth. The overall CP rate for neonatal survivors fell from 2.5 out of every 1000 in 1984 to 1986 to 1.7 in 1993 to 1995. The rate for those weighing less than 1000 g rose to 90 out of every 1000 neonatal survivors in 1987 to 1989 and then fell to 57 in 1993 to 1995. A similar pattern is seen among infants weighing 1000 to 1499 g at birth, the rate rising to 77 in 1987 to 1988 and then falling to 40 in 1993 to 1995. The rate of severe motor disability among infants weighing less than 1500 g also decreased (24.6 in 1984-1986 to 12.5 in 1993-1995). The relation of these findings to changes in perinatal care in the early 1990s is not known.

Factors influencing growth of Acanthopagrus butcheri (Sparidae) in a eutrophic estuary have changed over time

2016-01-01

The overall growth of Acanthopagrus butcheri in the eutrophic Swan River Estuary has previously been shown to decline between 1993-95 and 2007-11. This was attributed to the effects of an increase in hypoxia on A. butcheri in deeper water, brought about by reductions in freshwater flushing, and to density-dependent effects as this species became concentrated in the better-oxygenated, nearshore shallow waters. In the present study, a year-effect model was developed that provided a good fit to the lengths at age and could thus be used to explore the following: 1) The extent to which somatic growth of A. butcheri differed between years in the above two periods and within the later period, which was extended to include data for 2012 to 2014, and 2) whether annual growth in 2007-14 was related to temperature and/or freshwater discharge. Annual length increments for females and males during the second year of life, predicted from the model and when using a common initial length, were almost invariably less in each year in 2007-14 than in 1993-95. In 2007-14, these predicted increments varied by ˜2 times for both females and males and were positively correlated with average temperature during the main growth phase of A. butcheri. They were not significantly correlated, however, with freshwater discharge in the preceding cool wet 'winter' months, when the vast majority of rainfall occurs. The demonstration that the growth of A. butcheri was positively correlated with temperature for years in the latter period is consistent with the metabolic theory of ecology and contrasts with growth declining between 1993-95 and 2007-14 when temperatures were increasing. Thus, any influence of temperature on growth between those periods was overridden by the effects of other factors, i.e. hypoxia and related changes in density. As A. butcheri completes its life cycle within its natal estuary and has plastic biological characteristics, it is an ideal candidate for use as an indicator of the health of an estuary and for hypothesising on the effects of climate change on fish species.

With the improved prognosis in patients with autosomal dominant polycystic kidney disease (ADPKD), causes of death and the risk of cancer might have changed. This was investigated in a Danish population with ADPKD and end-stage renal disease (ESRD) between 1 January 1993 and 31 December 2008. Data were retrieved from three Danish national registries and a total of 823 patients were identified of which 431 had died during the study period. The 16 years were divided into two 8-year periods and the causes of death were divided into six categories: cancer, cardiovascular, cerebrovascular, infection, other and unknown. Cardiovascular disease was the major cause of death. A multivariate competing risk model comparing the two 8-year periods, adjusted for age at ESRD, gender and treatment modality, showed that deaths from cardiovascular disease decreased by 35% [hazard ratios (HR) 0.65, P=0.008] and deaths from cerebrovascular disease decreased by 69% (HR 0.31, P=0.0003) from the first to the second time period. There were no significant changes between the time periods in death from cancer, infection, other or unknown. From the first to the second 8-year interval, the prevalence of cancer increased by 35% (P=0.0002) while the cancer incidence was stable. In Danish patients with ADPKD and ESRD, there was a significant reduction in cardiovascular and cerebrovascular deaths from 1993 to 2008. The prevalence of cancer increased without significant change in cancer incidence or deaths from cancer.

The effects of an "El Niño" southern oscillation event on reproduction in male and female blue-footed boobies, Sula nebouxii.

This study attempted to determine endocrine correlates of reproductive success in relation to major deleterious environmental conditions. In 1992, an El Niño southern oscillation event resulted in complete reproductive failure in a colony of blue-footed boobies, Sula nebouxi, on Isla Isabel in the Pacific Ocean off San Blas, Nayarit, Mexico (21.5 degrees N, 105.5 degrees W). In 1993, the El Niño event had waned and reproductive success was high. The mean sea surface temperature in 1992 was 26.69 degrees, the warmest year for 11 years of data (mean, 25.63 degrees ). In 1993, mean sea surface temperature was 25.75 degrees. Plasma levels of testosterone were highest during the egg-laying period in 1993 and declined markedly during incubation. There were no differences between males and females. Comparisons of testosterone levels between 1992 and 1993 (egg-laying time point removed for 1993) showed no significant differences. Thus reproductive failure during an El Niño year was not related to testosterone levels. Baseline plasma levels of corticosterone did not change over the nesting cycle in either sex. There was a trend for plasma levels of corticosterone to be higher in males and females during the earlier stages of breeding in 1992 compared with 1993, and if all levels were combined within years then females showed significantly higher plasma levels of corticosterone in the El Niño year. Plasma levels of corticosterone showed marked increases following capture and handling in both sexes and at every stage of the breeding cycle in each year. There was no variation in the adrenocortical responses to stress with year or stage of nesting in males. However, in females, maximum corticosterone levels were greatest during the parental phase of 1992, the El Niño year, when all nests ultimately failed. Comparisons of the dynamics of corticosterone changes during the capture stress protocol revealed no correlations with body mass in 1992 or 1993. These data suggest that although massive reproductive failure in the El Niño year was not related to testosterone levels, baseline circulating concentrations of corticosterone may have a role in inhibiting onset of breeding. In contrast, after the nesting cycle has been initiated, increased adrenocortical sensitivity to acute stress may be involved in nest abandonment. Copyright 1999 Academic Press.

Distribution, population status and trends of kittlitz's murrelet brachyramphus brevirostris in lower cook inlet and kachemak bay, Alaska

Lower Cook Inlet (LCI) in south-central Alaska is unusual among the breeding areas of Kittlitz's Murrelet Brachyramphus brevirostris because of human impacts on the marine and terrestrial environments and because of the lack of tidewater glaciers. In LCI the Kittlitz's Murrelet co-exists with the more abundant Marbled Murrelet, which complicates abundance estimates because of the difficulty of species identification. We compared survey data for an area with overlapping coverage in LCI (Core area) in 1993 (June) and from 1996 to 1999 (July-early August). Within this LCI Core area, the surveys in 1996-1999 estimated ~1600 Kittlitz's Murrelets and ~17 000 Marbled Murrelets, including prorated unidentified murrelets. The Kittlitz's Murrelet population declined between 1993 and 1999 at 26% per annum (84% overall). Simultaneously, Marbled Murrelets declined by 12% per annum (56% overall), though the decline was not statistically significant. Declines were estimated conservatively because the 1993 survey was conducted in June, when both murrelet species are less abundant on the water. We also surveyed Kachemak Bay, a large embayment of LCI, during mid-summer (July) of 2005-2007 and estimated a population of 2047 Kittlitz's Murrelets (SD 1120, n = 3 years) residing primarily in the inner bay. Marbled Murrelets numbered 11 040 (SD 1306) and were found throughout the bay. On one transect set in inner Kachemak Bay, Kittlitz's Murrelet density in late summer (1-16 August) declined 7.5% per annum between 1988 and 2007 (n = 6 years), and Marbled Murrelet density increased 4.9% per annum. On two other transect sets in the inner bay, however, neither murrelet species showed a change in density between 1996 and 2007. Inner Kachemak Bay is a persistent hotspot for Kittlitz's Murrelet and may attract murrelets from LCI and beyond. We recommend monitoring murrelet populations in Kachemak Bay, although Kittlitz's Murrelets likely move between the main body of Cook Inlet and Kachemak Bay, and a complete LCI survey is needed to gauge regional population trends.

The principles and underlying cost bases of the 1977 and 1982 Space Shuttle Reimbursement Policies are compared and contrasted. Out-of-pocket cost recovery has been chosen as the base of the price for the 1986-1988 time period. With this cost base, it is NASA's intent to recover the total cost of consumables and the launch and flight operations costs added by commercial and foreign customers over the 1986-1988 time period. Beyond 1988, NASA intends to return to its policy of full cost recovery.

The success of primary stroke prevention for children with sickle cell disease (SCD) throughout the United States is unknown. Therefore, we aimed to generate national incidence rates of hospitalization for stroke in children with sickle cell disease (SCD) before and after publication of the Stroke Prevention Trial in Sickle Cell Anemia (STOP trial) in 1998. We performed a retrospective trend analysis of the 1993-2009 Nationwide Inpatient Sample and Kids' Inpatient Databases. Hospitalizations for SCD patients 0-18 years old with stroke were identified by ICD-9CM code. The primary outcome, the trend in annual incidence rate of hospitalization for stroke in children with SCD, was analyzed by linear regression. Incidence rates of hospitalization for stroke before and after 1998 were compared by the Wilcoxon rank-sum test. From 1993 to 2009, 2,024 hospitalizations were identified for stroke. Using the mean annual incidence rate of hospitalization for stroke from 1993 to 1998 as the baseline, the rate decreased from 1993 to 2009 (point estimate = -0.022/100 patient years [95% CI, -0.039, -0.005], P = 0.027). The mean annual incidence rate of hospitalization stroke decreased by 45% from 0.51 per 100 patient years in 1993-1998 to 0.28 per 100 patient years in 1999-2009 (P = 0.008). Total hospital days and charges attributed to stroke also decreased by 45% and 24%, respectively. After publication of the STOP trial and hydroxyurea licensure in 1998, the incidence of hospitalization for stroke in children with SCD decreased across the United States, suggesting that primary stroke prevention has been effective nationwide, but opportunity for improvement remains.

Objectives To examine 12-month prevalence of perceived bullying at work for doctors in different job categories and medical disciplines in 1993, 2004 and 2014–2015, and personality traits, work-related and health-related factors associated with perceived workplace bullying. Design Cross-sectional questionnaire surveys in 1993, 2004 and 2014–2015 where the 2004 and the 2012–2015 samples are partly overlapping. Setting Norway. Participants Response rates were 72.8% (2628/3608) in 1993, 67% (1004/1499) in 2004 and 78.2% (1261/1612) in 2014–2015. 485 doctors responded both in 2004 and 2014–2015. Outcome measure Perceived bullying at work from colleagues or superiors at least a few times a month during the last year. Results Between the samples from 1993, 2004 and 2014–2015, there were no significant differences in the prevalence of perceived bullying at work. More senior hospital doctors and surgeons reported being bullied. Doctors with higher scores on the personality trait neuroticism were more likely to perceive bullying, as were female doctors, doctors with poor job satisfaction and poor self-rated health. Conclusions The fraction of doctors who experienced bullying at work was stable over a 20-year period. Psychological, psychosocial and cultural factors are predictors of perceived bullying.

Retrospective analysis results of gestational trophoblastic neoplasia treatment according to prognostic scoring and staging system FIGO/WHO in Centre for gestational trophoblastic disease Ministry of Health the Slovak Republic Bratislava in the years 1993-2012. The treatment of gestational trophoblastic neoplasia (GTN) in the Czech and Slovak Republics started in 1955 and lasted till 1993. After the split of the former Czechoslovakia the Centre for gestational trophoblastic disease was created in Slovakia. 75 patients were treated in this Centre in the years 1993-2012. According to prognostic scoring and staging system FIGO/WHO 56 (75%) patients had low-risk gestational trophoblastic neoplasia and 19 (25%) of patients had high-risk gestational trophoblastic neoplasia. There were 41 patients (55%), 2 (3%), 24 (32%) and 8 (11%) in stage I., II., III. and IV. respectively. Total curability rate was 94.7% and mortality rate was 5.3%. Curability rate 100% was achieved in stage I & II and all placental site trophoblastic tumours (PSTT), 98.3% in stage III and 50% stage IV. In the years 1993-2012 the incidence of choriocarcinoma was one in 76 273 pregnancies and one in 53 203 deliveries. The incidence of other gestational trophoblastic neoplasia in the same years was for PSTT one in 533 753 pregnancies and one in 372 422 deliveries, invasive mole one in 145 611 pregnancies and one in 101 569 deliveries, and persistent GTN one in 40 043 pregnancies and one in 27 932 deliveries. 225-241 patients were treated in the same period of time in the Czech Republic with curability rate 98.2-98. 3%. Early detection and treatment in the centre for trophoblastic disease are crucial points in the manage-ment of gestational trophoblastic neoplasia, because the effective therapy of gestational trophoblastic neoplasia with high curability rate is available.

Dengue has been a major public health concern in Australia since it re-emerged in Queensland in 1992-1993. We explored spatio-temporal characteristics of locally-acquired dengue cases in northern tropical Queensland, Australia during the period 1993-2012. Locally-acquired notified cases of dengue were collected for northern tropical Queensland from 1993 to 2012. Descriptive spatial and temporal analyses were conducted using geographic information system tools and geostatistical techniques. 2,398 locally-acquired dengue cases were recorded in northern tropical Queensland during the study period. The areas affected by the dengue cases exhibited spatial and temporal variation over the study period. Notified cases of dengue occurred more frequently in autumn. Mapping of dengue by statistical local areas (census units) reveals the presence of substantial spatio-temporal variation over time and place. Statistically significant differences in dengue incidence rates among males and females (with more cases in females) (χ(2) = 15.17, d.f.  = 1, p<0.01). Differences were observed among age groups, but these were not statistically significant. There was a significant positive spatial autocorrelation of dengue incidence for the four sub-periods, with the Moran's I statistic ranging from 0.011 to 0.463 (p<0.01). Semi-variogram analysis and smoothed maps created from interpolation techniques indicate that the pattern of spatial autocorrelation was not homogeneous across the northern Queensland. Tropical areas are potential high-risk areas for mosquito-borne diseases such as dengue. This study demonstrated that the locally-acquired dengue cases have exhibited a spatial and temporal variation over the past twenty years in northern tropical Queensland, Australia. Therefore, this study provides an impetus for further investigation of clusters and risk factors in these high-risk areas.

To examine the length of stay and need for intensive care of people admitted with diabetic ketoacidosis (DKA) to a single centre between 1988 and 2011. Patients aged ≥15 years admitted for the first time with DKA (plasma glucose ≥ 10mmol/L and a bicarbonate concentration ≤15mmol/L and a pH <7.35, and raised plasma or urine ketones or anion gap) to Auckland City Hospital from 1988-2011 were identified retrospectively. The patients were divided into four cohorts (1988-1996; 1997-2001; 2002-2006; 2007-2011). Over this time period there was no significant change to the insulin infusion protocol. There were 576 admissions with DKA in 388 people over the 23 years. The mean age of the patients and glucose concentration at presentation to hospital fell significantly over time. The admission pH and bicarbonate concentration was higher in more recent cohorts. The length of stay and need for intensive care admission fell significantly over time, but the number of patients subsequently readmitted with DKA remained high. In-hospital mortality remained low. DKA remains an important reason for admission to this hospital, but the severity of DKA at presentation has reduced over time. The need for intensive care admission and length of stay has fallen dramatically.

China Energy Databook. Revision 4

1996-09-01

The Energy Analysis Program at LBL first became involved in Chinese energy issues through a joint China-US symposium on markets and energy demand held in Nanjing Nov. 1988. EAP began to collaborate on projects with the Energy Research Institute of China`s State Planning Commission. It was decided to compile, assess, and organize Chinese energy data. Primary interest was to use the data to help understand the historical evolution and likely future of the Chinese energy system; thus the primary criterion was to relate the data to the structure of energy supply and demand in the past and to indicate probablemore » developments (eg, as indicated by patterns of investment). Caveats are included in forewords to both the 1992 and 1996 editions. A chapter on energy prices is included in the 1996 edition. 1993 energy consumption data are not included since there was a major disruption in energy statistical collection in China that year.« less

A trend analysis of ergonomic research themes in Taiwan.

Lin, Chih-Long

2015-01-01

This paper examines the development of ergonomics in Taiwan by analysing 1404 scientific articles published by 113 permanent members of the Ergonomics Society of Taiwan (EST). Each article was classified by key words and abstract content. Each article was also coded by period of publication (1971-1992 (first period), 1993-1997 (second period), 1998-2002 (third period), 2003-2007 (fourth period), and 2008-2012 (fifth period), and against 13 topic categories. The results show that rate of publication has increased by approximately 100 articles every five years since 1993.The most popular topic was ergonomics assessment and analysis techniques in the first period, force exertion-related research in the second period, product design and evaluation in the third period, occupational safety and health in the fourth period and human-computer interface in the fifth period. Each of these is highly relevant to current contemporary issues around the world. Finally, potential areas for future ergonomics research in Taiwan are discussed. This study investigates the trends in academic papers published by members of the EST. Over time, topics have shifted from ergonomics evaluation methods to occupational safety and health, and human–computer interaction. The findings should be considered as important references for planning the future of ergonomics in Taiwan.

To investigate whether the incidence of cervical intraepithelial neoplasia (CIN), in particular of high grade CIN, increased in Berlin during the period 1970-1989 and whether the ages of women with CIN had decreased. In the former German Democratic Republic, which had a highly centralized public health system, all gynecologic operations performed on women living in the Mitte district of Berlin were carried out during the period 1970-1989 (when the Berlin Wall fell) in the gynecologic clinic of the Charité Hospital. The incidence of all CIN increased from year to year over the observation period: 0.04% (1970-1971), 0.10% (1980-1981), 0.39% (1988-1989). There was a particularly high increase in the incidence of high grade intraepithelial neoplasms (CIN 3): 0.016% (1970-1971), 0.056% (1980-1981), 0.25% (1988-1989). With a virtually unchanged age distribution for women in the Mitte district of Berlin, the median age of women with CIN 3 decreased significantly from 1970 to 1989, from 39.5 (1970) to 33 (1989) (P < .001). The increase in the incidence of CIN, especially of high grade CIN, as well as the reduction in age for onset of the disease, makes high participation in screening necessary, above all among young women.

Inequality in fertility rate and modern contraceptive use among Ghanaian women from 1988–2008

PubMed Central

2013-01-01

Background In most resource poor countries, particularly sub-Saharan Africa, modern contraceptive use and prevalence is unusually low and fertility is very high resulting in rapid population growth and high maternal mortality and morbidity. Current evidence shows slow progress in expanding the use of contraceptives by women of low socioeconomic status and insufficient financial commitment to family planning programs. We examined gaps and trends in modern contraceptive use and fertility within different socio-demographic subgroups in Ghana between 1988 and 2008. Methods We constructed a database using the Women’s Questionnaire from the Ghana Demographic and Health Survey (GDHS) 1988, 1993, 1998, 2003 and 2008. We applied regression-based Total Attributable Fraction (TAF); we also calculated the Relative and Slope Indices of Inequality (RII and SII) to complement the TAF in our investigation. Results Equality in use of modern contraceptives increased from 1988 to 2008. In contrast, inequality in fertility rate increased from 1988 to 2008. It was also found that rural–urban residence gap in the use of modern contraceptive methods had almost disappeared in 2008, while education and income related inequalities remained. Conclusions One obvious observation is that the discrepancy between equality in use of contraceptives and equality in fertility must be addressed in a future revision of policies related to family planning. Otherwise this could be a major obstacle for attaining further progress in achieving the Millennium Development Goal (MDG) 5. More research into the causes of the unfortunate discrepancy is urgently needed. There still exist significant education and income related inequalities in both parameters that need appropriate action. PMID:23718745

Observed trends in ambient concentrations of C 2-C 8 hydrocarbons in the United Kingdom over the period from 1993 to 2004

NASA Astrophysics Data System (ADS)

Dollard, G. J.; Dumitrean, P.; Telling, S.; Dixon, J.; Derwent, R. G.

Hourly measurements of up to 26 C 2-C 8 hydrocarbons have been made at eight urban background sites, three urban-industrial sites, a kerbside and a rural site in the UK from 1993 onwards up until the end of December 2004. Average annual mean benzene and 1,3-butadiene concentrations at urban background locations have declined at about -20% per year and the observed declines have exactly mimicked the inferred declines in benzene and 1,3-butadiene emissions over the same period. Ninety-day rolling mean concentrations of ethylene, propylene, n- and i-butane, n- and i-pentane, isoprene and propane at urban and rural sites have also declined steadily by between -10% and -30% per year. Rolling mean concentrations of acetylene, 2- and 3-methylpentane, n-hexane, n-heptane, cis- and trans-but-2-ene, cis- and trans-pent-2-ene, toluene, ethylbenzene and o-, m- and p-xylene at a roadside location in London have all declined at between -14% and -21% per year. These declines demonstrate that motor vehicle exhaust catalysts and evaporative canisters have effectively and efficiently controlled vehicular emissions of hydrocarbons in the UK. Urban ethane concentrations arising largely from natural gas leakage have remained largely unchanged over this same period.

A map was prepared that shows the net change in the potentiometric surface of the Magothy aquifer (in the Cretaceous Magothy Formation) in southern Maryland from the fall of 1986 to the fall of 1988. The map, based on water level measurements from 79 observation wells, shows that during the 2 year period the potentiometric surface declined less than 5 ft in most of the northern part of the study area and more than 10 ft in a 4-sq-mi area in northern Charles County. Net water-level rises of as much as 2 ft were measured in central Charles County. (USGS)

Modelling postfledging survival and age-specific breeding probabilities in species with delayed maturity: a case study of Roseate Terns at Falkner Island, Connecticut

We modeled postfledging survival and age-specific breeding probabilities in endangered Roseate Terns (Sterna dougallii) at Falkner Island, Connecticut, USA using capture-recapture data from 1988-1998 of birds ringed as chicks and as adults. While no individuals bred as 2-yr-olds during this period, about three-quarters of the young that survived and returned as 3-yr-olds nested, and virtually all surviving birds had begun breeding by the time they reached 5 years of age. We found no evidence of temporal variation in age of first breeding of birds from different cohorts. There was significant temporal variation in the annual survival of adults and the survival over the typical 3-yr maturation period of prebreeding birds, with extremely low values for both groups from the 1991 breeding season. The estimated overwinter survival rate (0.62) for adults from 1991-1992 was about three-quarters the usual rate of about 0.83, but the low survival of fledglings from 1991 resulted in less than 25% of the otherwise expected number of young from that cohort returning as breeding birds; this suggests that fledglings suffered a greater proportional decrease in survival than did adults. The survival estimates of young from 1989 and 1990 show that these cohorts were not negatively influenced by the events that decimated the young from 1991, and the young from 1992 and 1993 had above-average survival estimates. The apparent decrease since 1996 in development of fidelity of new recruits to this site is suspected due mainly to nocturnal disturbance and predation of chicks causing low productivity.

Objective To review retrospectively a 4-year experience with pediatric surgical networking at a major academic medical center in the Midwest. Background The growth of managed care in the United States during the past decade has had a major impact on the practice of medicine in general, but especially on academic medicine. In some academic medical centers, the loss of market share has not only affected clinical activity but has also compromised the educational and research missions of these institutions. Methods At the authors’ institution, a networking strategy in pediatric surgery was established in 1993 and implemented on July 1, 1994. In 1994, one new satellite practice was established; over the next 4 years, four additional practices were added, including one in another state. To assess the impact on financial status, clinical activity, education, and academic productivity, the following parameters were analyzed: gross and net revenue, surgical cases, clinic visits, ranking of the pediatric surgery residency, publications, grant support, and development and endowment funds. Results Gross and net revenue increased from $3,273,000 and $302,000 in 1993 to $10,087,000 and $2,826,000, respectively, in 1998. Surgical cases and clinic visits increased from 1240 and 3751 in 1993 to 5872 and 11,604, respectively, in 1998. At the medical center’s children’s hospital, surgical cases and clinic visits increased from 1240 and 3751 to 2592 and 4729 during the same time period. During this 4-year period, the faculty increased from 4 to 11. Since 1997, the National Resident Matching Program has provided data on how pediatric surgery residency candidates ranked a training program. In 1997, this program received the second-most one to five rankings; in 1998, it tied for first. This exceeds the faculty’s perception of previous years’ rankings. Publications increased from 26 in 1993 to a peak number of 62 in 1996; in 1997 and 1998 the publications were 48 and 37, respectively. External grant support increased from $139,882 in 1993 to a total of $6,109,971 in 1998. Development and endowment funds increased from $103,559 in 1993 to $2,702,2777 in 1998. Conclusions Pediatric surgical networking at the authors’ institution has had a markedly positive impact on finances, clinical activity, education, and academic productivity during a 4-year period. The residency training program appears to have improved in popularity among candidates, probably because of the increased referral of complex cases to the medical center from the various networking satellites. External grant support and basic laboratory research significantly increased, most likely because of the greater number of faculty with protected time for research recruited. Development and endowment funds dramatically grew because of the excellent fiscal health of the pediatric surgical program. This experience may serve as a model for other academic surgical specialties. PMID:10493480

Northern hemisphere total ozone values from 1989-1993 determined with the NOAA-11 Solar Backscatter Ultraviolet (SBUV/2) instrument

1994-01-01

Determinations of global total ozone amounts have been made from recently reprocessed measurements with the SBUV/2 on the NOAA-11 environmental satellite since January 1989. This data set employs a new algorithm and an updated calibration. Comparisons with total ozone amounts derived from a significant subset of the global network of Dobson spectrophotometers shows a 0.3% bias between the satellite and ground measurements for the period January 1989-May 1993. Comparisons with the data from individual stations exhibit differing degrees of agreement which could be due to the matchup procedures and also to the uncertainties in the Dobson data. The SBUV/2 data set discussed here traces the Northern Hemisphere total ozone from 1989 to the present, showing a marked decrease from the average of those years starting in the summer of 1992 and continuing into 1993, with an apparent returning to more normal levels in late 1993.

2017-01-01

Objective We aimed to investigate all-cause and cause-specific mortality among ethnic German migrants from the former Soviet Union by different immigration periods to describe associations with migration pattern and mortality. Design We used pooled data from three retrospective cohort studies in Germany. Participants Ethnic German migrants from the former Soviet Union (called resettlers), who immigrated to Germany since 1990 to the federal states North Rhine-Westphalia and Saarland and to the region of Augsburg (n=59 390). Outcome All-cause and cause-specific mortality among resettlers in comparison to the general German population, separated by immigration period. Methods Immigration periods were defined following legislative changes in German immigration policy (1990–1992, 1993–1995, 1996+). Resettlers’ characteristics were described accordingly. To investigate mortality differences by immigration period, we calculated age-standardised mortality rates (ASRs) and standardised mortality ratios (SMRs) of resettlers in comparison to the general German population. Additionally, we modelled sex-specific ASRs with Poisson regression, using age, year and immigration period as independent variables. Results The composition of resettlers differed by immigration period. Since 1993, the percentage of resettlers from the Russian Federation and non-German spouses increased. Higher all-cause mortality was found among resettlers who immigrated in 1996 and after (ASR 628.1, 95% CI 595.3 to 660.8), compared with resettlers who immigrated before 1993 (ASR 561.8, 95% CI 537.2 to 586.4). SMR analysis showed higher all-cause mortality among resettler men from the last immigration period compared with German men (SMR 1.11, 95% CI 1.04 to 1.19), whereas resettlers who immigrated earlier showed lower all-cause mortality. Results from Poisson regression, adjusted for age and year, corroborated those findings. Conclusions Mortality differences by immigration period suggest different risk-factor patterns and possibly deteriorated integration opportunities. Health policy should guard the consequences of immigration law alterations with respect to changing compositions of migrant groups and their health status. PMID:29259065

Thyroid hormone use: trends in the United States from 1960 through 1988.

PubMed

Kaufman, S C; Gross, T P; Kennedy, D L

1991-01-01

Thyroid hormone preparations comprised over 1% of all prescriptions filled by retail pharmacies during 1988 in the conterminous United States, i.e., the 48 contiguous states. Their large market share gives the patterns of their use substantial public health importance. This article describes prescription thyroid hormone use in the United States from 1960 through 1988, using pharmaceutical marketing research data collected from panels of retail pharmacies and office-based physicians. Although the use of natural products has declined by over 50% since 1960, about one fourth of all thyroid hormone prescriptions were for natural preparations as recently as 1988. Per capita thyroid mentions (i.e., patient-physician contacts during which a thyroid agent of any kind was recommended, prescribed, dispensed, administered, ordered to be given by a hospital, or given as a sample) doubled during this period among those over 59 years old. Per capita mentions for synthetic thyroid products increased fourfold and tenfold among men and women in this age group, respectively. Use for weight loss, despite the label's boxed warning indicating it to be ineffective and potentially dangerous, has diminished but persists. Obesity was second only to hypothyroidism among the diagnoses underlying thyroid product mentions.

New patterns in epidemiological characteristics of people living with HIV infection (PLWH) and the introduction of Highly Active Antiretroviral Therapy (HAART) have changed the profile of hospital admissions in this population. The aim of this study was to evaluate trends in hospital admissions, re-admissions, and mortality rates in HIV patients and to analyze the role of HCV co-infection. A retrospective cohort study conducted on all hospital admissions of HIV patients between 1993 and 2013. The study time was divided in two periods (1993-2002 and 2003-2013) to be compared by conducting a comparative cross-sectional analysis. A total of 22,901 patient-years were included in the analysis, with 6917 hospital admissions, corresponding to 1937 subjects (75% male, mean age 36±11 years, 37% HIV/HCV co-infected patients). The median length of hospital stay was 8 days (5-16), and the 30-day hospital re-admission rate was 20.1%. A significant decrease in hospital admissions related with infectious and psychiatric diseases was observed in the last period (2003-2013), but there was an increase in those related with malignancies, cardiovascular, gastrointestinal, and chronic respiratory diseases. In-hospital mortality remained high (6.8% in the first period vs. 6.3% in the second one), with a progressive increase of non-AIDS-defining illness deaths (37.9% vs. 68.3%, P<.001). The admission rate significantly dropped after 1996 (4.9% yearly), but it was less pronounced in HCV co-infected patients (1.7% yearly). Hospital admissions due to infectious and psychiatric disorders have decreased, with a significant increase in non-AIDS-defining malignancies, cardiovascular, and chronic respiratory diseases. In-hospital mortality is currently still high, but mainly because of non-AIDS-defining illnesses. HCV co-infection increased the hospital stay and re-admissions during the study period.

Lacombe, Pierre J.; Rosman, Robert

1997-01-01

Water levels in 722 wells in the Coastal Plain of New Jersey, Pennsylvania, and northeastern Delaware were measured during October and November 1993 and were used to define the potentiometric surface of the eight major confined aquifers of the area. Isochlors (lines of equal chloride concentration) for 250 and 10,000 milligrams per liter are included to show the extent of freshwater in each of the aquifers. Estimated water withdrawals from the eight major confined aquifers are reported for 1978-94. Water-withdrawal and water-level maps including isochlors were constructed for the Cohansey aquifer of Cape May County, the Atlantic City 800-foot sand, the Piney Point aquifer, the Wenonah-Mount Laurel aquifer, the Englishtown aquifer system, the Upper Potomac-Raritan-Magothy, the Middle and undifferentiated Potomac-Raritan-Magothy, and the Lower Potomac-Raritan-Magothy aquifers. From 1988 to 1993, water levels near the center of the large cones of depression in the Middlesex-Monmouth County area rose as much as 120 ft in the Wenonah-Mount Laurel aquifer and Englishtown aquifer system, 40 ft in the Upper Potomac-Raritan-Magothy aquifer, and 96 ft in the Middle and undifferentiated Potomac-Raritan-Magothy aquifers. Large cones of depression in the potentiometric surface of aquifers of the Potomac-Raritan-Magothy aquifer system in the Burlington-Camden-Gloucester area remained at about the same altitude; that is, the potentiometric surface neither rose nor fell in the aquifers by more than 5 feet. In the same area, water levels in the Englishtown aquifer system were static, whereas the water levels in the Wenonah-Mount Laurel aquifer declined 5 to 20 feet, forming an expanded cone of depression. Water levels in the Cohansey, Atlantic City 800-foot sand, and Piney Point aquifers declined by 1 to 10 feet during 1988?93.

To investigate how anthropogenic activity might affect large carnivores, we studied the behaviour of spotted hyenas (Crocuta crocuta) during two time periods. From 1996 to 1998, we documented the ecological correlates of space utilization patterns exhibited by adult female hyenas defending a territory at the edge of a wildlife reserve in Kenya. Hyenas preferred areas near dense vegetation but appeared to avoid areas containing the greatest abundance of prey, perhaps because these were also the areas of most intensive livestock grazing. We then compared hyena behaviour observed in 1996–98 with that observed several years earlier and found many differences. Female hyenas in 1996–98 were found farther from dens, but closer to dense vegetation and to the edges of their territory, than in 1988–90. Recent females also had larger home ranges, travelled farther between consecutive sightings, and were more nocturnal than in 1988–90. Finally, hyenas occurred in smaller groups in 1996–98 than in 1988–90. We also found several changes in hyena demography between periods. We next attempted to explain differences observed between time periods by testing predictions of hypotheses invoking prey abundance, climate, interactions with lions, tourism and livestock grazing. Our data were consistent with the hypothesis that increased reliance on the reserve for livestock grazing was responsible for observed changes. That behavioural changes were not associated with decreased hyena population density suggests the behavioural plasticity typical of this species may protect it from extinction.

A management-by-objective approach was used by the health care administration of the Kupat Holim Sick Fund to improve care of hypertension in 20 family practices in the city of Ashdod in central Israel. The doctor-nurse teams in these clinics met jointly on a regular basis with a physician-instructor, reviewed the results of their care of hypertension and discussed ways of improving it. Over a seven-year period, until 1988, the percentage of the population treated increased from 4.0% to 9.2% and percentage of treated patients who had diastolic pressure of 100 mmHg or more fell from 29.6% to 13.4%. Dropout rate ranged from 2.3% to 3.1% per year over the whole period. In 20 other practices in the Ashdod area in 1988 used for comparison, only 5.9% of the population was treated and the per cent treated was less than Ashdod for all age groups above 30. Dropout rate was higher, averaging 9.8% per year, and the percentage of patients with diastolic pressures of 100 mmHg or more was higher (18.1%). Thus the use of regular discussions with feedback to the health care team was associated with better detection, treatment and follow-up of hypertension.

Over the past several years, world scientific attention was focused on the rapid and unanticipated decrease in the abundance of ozone over Antarctica during the Austral spring. A major aircraft campaign was conducted from December 1988 to February 1989 in response to the recently published Ozone Trends Panel Report which found that the largest decreases in Arctic ozone occurred during January to February at latitudes near the edge of the Arctic vortex. This atlas provides a complete set of TOMS ozone measurements over Europe and the North Atlantic for the duration of the experiment. These were the orbital TOMS measurements provided to the experimenters in near-real-time. In addition, a set of Northern Hemisphere TOMS ozone measurements for the period December 26, 1988 to March 20, 1989 is presented. A comparison of January and February 1989 mean ozone values to prior years is also presented.

1988-01-01

Fiscal year 1988 has been a significant, rewarding, and exciting period for Lawrence Livermore National Laboratory's nuclear testing program. It was significant in that the Laboratory's new director chose to focus strongly on the program's activities and to commit to a revitalized emphasis on testing and the experimental science that underlies it. It was rewarding in that revolutionary new measurement techniques were fielded on recent important and highly complicated underground nuclear tests with truly incredible results. And it was exciting in that the sophisticated and fundamental problems of weapons science that are now being addressed experimentally are yielding new challengesmore » and understanding in ways that stimulate and reward the brightest and best of scientists. During FY88 the program was reorganized to emphasize our commitment to experimental science. The name of the program was changed to reflect this commitment, becoming the Nuclear Test-Experimental Science (NTES) Program.« less

Advocacy and government action for cancer prevention in older persons.

PubMed

Bal, D G; Lloyd, J

1994-10-01

Government action and the advocacy activities that influence it are as important a concern for cancer control as they are for any other public issue. Policy advocacy strategies have proven themselves effective in cancer prevention efforts involving tobacco use and nutrition. Much of what has been learned from this experience can be applied with great effect in advocacy efforts for other cancer control measures. The implementation of Proposition 99, the 1988 tobacco tax initiative in California, illustrates the effectiveness of aggressive policy advocacy strategies such as provocative paid advertising, mobilization through coalitions, and community-level public relations, to bring about government action at all levels of government and in the private sector. Today, largely as a result of these activities, more than 70 of California's 471 cities have a 100% smokefree workplace and/or a 100% smokefree restaurant ordinance, and nearly 300 cities currently have ordinances that restrict smoking pollution and/or restrict youth access to cigarette vending machines. About 150 cities have ordinances that were either adopted or greatly strengthened since 1990 when the program hit the streets. Ironically, although the primary aim of these strategies has been to reduce uptake of tobacco use by adolescents, the program's gains so far--including the reduction in adult smoking prevalence from 26% in 1988 to 20% in 1993, for an estimated savings in 1993 alone of $386 million in direct medical costs in the state--have been the result of adult smokers quitting, especially those older than 50.

A 7.5-Year Dataset of SSM/I-Derived Surface Turbulent Fluxes Over Global Oceans

The surface turbulent fluxes of momentum, latent heat, and sensible heat over global oceans are essential to weather, climate and ocean problems. Wind stress is the major forcing for driving the oceanic circulation, while Evaporation is a key component of hydrological cycle and surface heat budget. We have produced a 7.5-year (July 1987-December 1994) dataset of daily, individual monthly-mean and climatological (1988-94) monthly-mean surface turbulent fluxes over the global oceans from measurements of the Special Sensor Microwave/Imager (SSM/I) on board the US Defense Meteorological Satellite Program F8, F10, and F11 satellites. It has a spatial resolution of 2.0x2.5 latitude-longitude. Daily turbulent fluxes are derived from daily data of SSM/I surface winds and specific humidity, National Centers for Environmental Prediction (NCEP) sea surface temperatures, and European Centre for Medium-Range Weather Forecasts (ECMWF) air-sea temperature differences, using a stability-dependent bulk scheme. The retrieved instantaneous surface air humidity (with a 25-km resolution) IS found to be generally accurate as compared to the collocated radiosonde observations over global oceans. The surface wind speed and specific humidity (latent heat flux) derived from the F10 SSM/I are found to be -encrally smaller (larger) than those retrieved from the F11 SSM/I. The F11 SSM/I appears to have slightly better retrieval accuracy for surface wind speed and humidity as compared to the F10 SSM/I. This difference may be due to the orbital drift of the F10 satellite. The daily wind stresses and latent heat fluxes retrieved from F10 and F11 SSM/Is show useful accuracy as verified against the research quality in si -neasurerrients (IMET buoy, RV Moana Wave, and RV Wecoma) in the western Pacific warm pool during the TOGA COARE Intensive observing period (November 1992-February 1993). The 1988-94 seasonal-mean turbulent fluxes and input variables derived from FS and F11 SSM/Is show reasonable patterns related to seasonal variations of atmospheric general circulation. This dataset of SSM/I-derived turbulent fluxes is useful for climate studies, forcing of ocean models, and validation of coupled ocean-atmosphere global models and can be accessed through the NASA/GSFC Distributed Active Archive Center.

Two asteroids showed indications of being binary. Analysis of the data for near-Earth asteroid, 3352 McAuliffe showed a second period of 20.86 h but no obvious mutual events (occultations and/or eclipses). The Hungaria asteroid, (24465) 2000 SX15, displayed similar characteristics. Furthermore, the primary (or only) period of 3.256 h cannot be reconciled with analysis from previous apparitions. Three asteroids showed signs of being in non-principal axis rotation (NPAR, "tumbling"). New values for absolute magnitude (H) were found for several Hungaria asteroids using either derived or assumed values of G. These new values were compared against those used in the WISE mission to determine diameters and albedos. In all cases where the WISE results featured an unusually high albedo for the asteroid in question, the new value of H resulted in an albedo that was significantly lower and closer to the expected value for type E asteroids, which are the likely members of the Hungaria collisional family.

Long-term changes in the statistical distribution of Dobson total ozone in selected Northern Hemisphere geographical regions

NASA Technical Reports Server (NTRS)

Krzyscin, Janusz W.

1994-01-01

The daily averages of total column amount of ozone taken in the period 1964-1988 at a network of 24 Dobson stations have been analyzed. Year-round data as well as summer data (May - Aug.) and winter data (Dec. - March) have been examined in the following regions: latitude bands (30 deg N - 39 deg N, 40 deg N - 52 deg N, 30 deg N - 60 deg N), North America, Europe, and Japan. To find year-to-year changes in the shape of the annual statistical distribution of total ozone (ASDTO) for these regions, we analyze trends in the following statistic characteristics of ASDTO: mean, standard deviation, median, and 10 and 90 percentiles. Time series of the statistical characteristics for the selected regions have been combined by averaging the individual stations values of these characteristics. The trends have been calculated by the multiple regression model adjusted for: the 11-year solar cycle, the Southern Oscillations effects, and for serial correlations. We have found that: a) in all regions (excluding Japan, North America), the shape of ASDTO has been drifting towards low ozone values. The drift seems to be not accompanied with a transformation in the shape of ASDTO. The drift speed (the rate of decrease in the annual means of total ozone) is of order 1-3 percent per decade (in the period 1970-1988). b) In Japan, the interannual changes in the shape of ASDTO have not been revealed. c) In North America, the drift of the year-round ASDTO (the year-round ASDTO comprises all the daily means of total ozone in a given year) has been accompanied with a transformation in the shape. The shape of the year round ASDTO becomes narrower. d) In all regions, except Japan and the band 30 deg - 39 deg N, the winter ASDTO (the winter ASDTO comprises the data taken in the period December in a given year through March next year) moves faster towards low ozone values than the summer ASDTO (the summer ASDTO comprises the data taken in the period May through August in a given year).

Acoustic Probe for Solid-Gas-Liquid Suspension

DOE Office of Scientific and Technical Information (OSTI.GOV)

Tavlarides, L.L.; Sangani, Ashok

The primary objective of the research project during the first funding period was to develop an acoustic probe to measure volume percent solids in solid-liquid slurries in the presence of small amounts of gas bubbles. This problem was addressed because of the great need for a non-invasive, accurate and reliable method for solids monitoring in liquid slurries in the presence of radiolytically generated gases throughout the DOE complex. These measurements are necessary during mobilization of salts and sediments in tanks, transport of these slurries in transfer lines to processing facilities across a site, and, in some instances, during high levelmore » waste processing. Although acoustic probes have been commonly used for monitoring flows in single-phase fluids (McLeod, 1967), their application to monitor two-phase mixtures has not yet fully realized its potential. A number of investigators in recent years have therefore been involved in developing probes for measuring the volume fractions in liquid solid suspensions (Atkinson and Kytomaa, 1993; Greenwood et al., 1993; Martin et al., 1995) and in liquid-liquid suspensions (Bonnet and Tavlarides, 1987; Tavlarides and Bonnet, 1988, Yi and Tavlarides, 1990; Tsouris and Tavlarides, 1993, Tsouris et al., 1995). In particular, Atkinson and Kytomaa (1993) showed that the acoustic technique can be used to determine both the velocity and the volume fraction of solids while Martin et al. (1995) and Spelt et al. (1999) showed that the acoustic probe can also be used to obtain information on the size distribution of the particles. In a recent testing of in-line slurry monitors with radioactive slurries suspended with Pulsair Mixers (Hylton & Bayne, 1999), an acoustic probe did not compare well with other instruments most probably due to presence of entrained gases and improper acoustic frequency range of interrogation. The work of the investigators cited has established the potential of the acoustic probe for characterizing/monitoring two-phase flows in relatively ideal, well-characterized suspensions. Two major factors which we judge has prevented its wide-spread use in the processing industry, particularly for dilute suspensions, is careful selection of the frequency range for interrogation and quantification and removal of the noise introduced by bubbles from the acoustic signal obtained from the suspension. Our research during the first funding period to develop an acoustic probe for solid-gas liquid suspensions has resulted in a theory, supported by our experiments, to describe small amplitude dilute suspensions (Norato, 1999, Spelt et al., 1999, Spelt et al., 2001). The theory agrees well with experimental data of sound attenuation up to 45 {approx}01% suspensions of 0.11 and 77 micron radius polystyrene particles in water and 0.4 to 40 vol %, suspensions of 32 micron soda-lime glass particles in water. Also, analyses of our attenuation experiments for solid-gas liquid experiments suggest the theory can be applied to correct for signal interference due to the presence of bubbles over a selected frequency range to permit determination of the solid-liquid volume fraction. Further, we show experimentally that a reliable linear dependency of weight percent solids with attenuation is obtained for low weight fractions at high frequencies of interrogation where bubble interference is minimal. There was a collaborative effort during the first funding period with the Pacific Northwest National Laboratories in that Dr. Margaret Greenwood was a co-investigator on the project. Dr. Greenwood provided a high level of experimental knowledge and techniques on ultrasound propagation, measurement and data processing. During the second funding period the slurry test loop at Oak Ridge National Laboratories under the direction of Mr. Tom Hylton will be employed to demonstrate the measurement capabilities of the prototype acoustic monitor.« less

Parsing demographic effects of canine pParvovirus on a Minnesota wolf population

USGS Publications Warehouse

Mech, L. David; Goyal, Sagar M.

2011-01-01

We examined 35 years of relationships among wolf (Canis lupus) pup survival, population change and canine parvovirus (CPV) seroprevalence in Northeastern Minnesota to determine when CPV exerted its strongest effects. Using correlation analysis of data from five periods of 7-years each from 1973 through 2007, we learned that the strongest effect of CPV on pup survival (r = -0.73) and on wolf population change (r = -0.92) was during 1987 to 1993. After that, little effect was documented despite a mean CPV seroprevalence from 1994 of 2007 of 70.8% compared with 52.6% during 1987 to 1993. We conclude that after CPV became endemic and produced its peak effect on the study population, that population developed enough immunity to withstand the disease.

Changing Educational Inequalities in India in the Context of Affirmative Action

PubMed Central

DESAI, SONALDE; KULKARNI, VEENA

2008-01-01

Indian society suffers from substantial inequalities in education, employment, and income based on caste and ethnicity. Compensatory or positive discrimination policies reserve 15% of the seats in institutions of higher education and state and central government jobs for people of the lowest caste, the Scheduled Caste; 7.5% of the seats are reserved for the Scheduled Tribe. These programs have been strengthened by improved enforcement and increased funding in the 1990s. This positive discrimination has also generated popular backlash and on-the-ground sabotage of the programs. This paper examines the changes in educational attainment between various social groups for a period of nearly 20 years to see whether educational inequalities have declined over time. We use data from a large national sample survey of over 100,000 households for each of the four survey years—1983, 1987–1988, 1993–1994, and 1999–2000—and focus on the educational attainment of children and young adults aged 6–29. Our results show a declining gap between dalits, adivasis, and others in the odds of completing primary school. Such improvement is not seen for Muslims, a minority group that does not benefit from affirmative action. We find little improvement in inequality at the college level. Further, we do not find evidence that upper-income groups, the so-called creamy layer of dalits and adivasis, disproportionately benefit from the affirmative action programs at the expense of their lower-income counterparts.

Although prevalence studies show girls are more frequently sexually abused than boys, a significant proportion of boys also experience child sexual abuse (CSA). The challenges for public policy are amplified for boys due to less developed public and professional sensitisation to boys' experiences, conceptions of masculinity, and less research on boys including into reporting trends and outcomes. We conducted a 20-year longitudinal time-trend analysis of government data to identify reporting trends and report outcomes for CSA in Victoria, Australia from 1993 to 2012. We stratified by child gender and reporter status. Results indicate a new sensitisation to CSA, especially for boys, although this trend was not stable. Marked change occurred in the last five years, likely influenced by major social and political events. Comparison over time revealed that from 1993 to 2012, the rate of reporting of boys increased 2.6-fold whereas there was a 1.5-fold increase for girls. Comparing genders, with regards to rate of reporting, in 1993, the sex ratio of girls to boys was 2:1, while by 2012 this ratio changed to 1.14:1. Reports by police and other mandated reporters accounted for the majority of the increase in reports over the 20-year period, suggesting unequal sensitisation. Positive report outcomes (i.e. substantiations, findings of harm, and referral to services) increased twelve-fold for boys, and nearly five-fold for girls, indicating the increased levels of reports were based in actual clinical need. Most of this increase occurred from 2009 to 2012, influenced by a compound of social, political and agency-related factors. Copyright © 2017 Elsevier Ltd. All rights reserved.

[Reduced number of fatal and life-threatening reactions to food. Reporting by the medical profession has resulted in effective measures].

PubMed

Foucard, Tony; Yman, Ingrid Malmheden; Nordvall, Lennart

The results from the Swedish system for reporting severe and fatal reactions caused by food for the period 1993-96 were published in Lakartidningen in 1997. We now report the results for the period 1997-2003. The number of fatal cases has decreased from 1.75 to 0.86 per year and the number of life-threatening cases from 3 to I per year. The most gratifying result was the large decrease in severe reactions caused by soy, from 3 deaths and 6 life-threatening cases during the first 4-year period to just one life-threatening case during the following 7-year period. This reduction is probably largely due to an increased awareness of identified risk persons, but also to a reduced use of soy protein. The ongoing study illustrates the usefulness of a national system for reporting severe and fatal reactions caused by food.

To examine the presence of features of sales promotion in cigarette advertising in United States magazines, and to describe trends in youth (ages 12-17) exposure to such advertising (termed "promotional advertising"). Analysis of 1980-1993 annual data on: (a) total pages and expenditures for "promotional advertising" (advertising that contains features of sales promotion) in 36 popular magazines (all magazines for which data were available), by cigarette brand; and (b) readership characteristics for each magazine. We defined promotional advertising as advertisements that go beyond the simple advertising of the product and its features to include one or more features of sales promotion, such as coupons, "retail value added" promotions, contests, sweepstakes, catalogues, specialty item distribution, and sponsorship of public entertainment or sporting events. Total pages of, and expenditures for promotional advertising in magazines; and gross impressions (number of readers multiplied by the number of pages of promotional advertising) among youth and total readership. During the period 1980-1993, tobacco companies spent $90.2 million on promotional advertising in the 36 magazines. The proportion of promotional advertising appearing in "youth" magazines (defined as magazines with a greater than average proportion of youth readers) increased from 7% in 1980 to nearly 100% in 1987. Although youth readers represented only 19% of magazine readers, the proportion of youth gross impressions to total gross impressions of tobacco promotional advertising exceeded this value throughout the entire period 1985-1993, peaking at 33% in 1987. The five "youth" cigarette brands (defined as brands smoked by at least 2.5% of smokers aged 10-15 years in 1993) accounted for 59% of promotional advertising in all magazines, but for 83% of promotional advertising in youth magazines during the study period. In their magazine advertising, cigarette companies are preferentially exposing young people to advertisements that contain sales promotional features.

The purpose of this study was to evaluate gender differences in the authorship of original research articles by radiologists in two major American radiology journals, AJR and Radiology. In a retrospective bibliometric analysis, all original articles published in AJR and Radiology during three 3-year periods (1991-1993, 2001-2003, and 2011-2013) were reviewed to determine the gender of the first and corresponding radiology authors. In addition, radiologic subspecialty and country of the authors were also abstracted from each article. The gender of the first and corresponding authors could be determined for 10,043 of 10,228 authors (98.2%) of original research in radiology. Between the periods 1991-1993 and 2011-2013, the percentage of female authors significantly increased: from 20.4% to 34.4%, respectively, among first authors (p < 0.0001); and from 18.0% to 28.7%, respectively, among corresponding authors (p < 0.0001). There was a significant correlation between the gender of the first and corresponding authors (p < 0.05). In the 2011-2013 period, the proportion of female authors was highest in breast (64.2%) and pediatric (48.2%) and lowest in vascular and interventional (18.5%) and cardiac (21.0%) subspecialties. The proportion of female authors was the highest in The Netherlands (47.3%), South Korea (37.9%), France (36.2%), and Italy (33.6%). There was a significant increase in the female authorship of original research articles in two major American radiology journals between the periods 1991-1993 and 2011-2013.

Opportunities for ballistic missions to Halley's comet

Alternative strategies for ballistic missions to Halley's comet in 1985-86 are described. A large scientific return would be acquired from a ballistic Halley intercept in spite of the high flyby speeds that are associated with this mission mode. The possibility of retargeting the cometary spacecraft to additional comets after the Halley intercept also exists. Two cometary spacecraft of identical design would be used to carry out four separate cometary encounters over a 3 year period. One spacecraft would intercept Halley's comet before its perihelion passage in December 1985 and then go on to comet Borrelly with an encounter in January 1988. The other spacecraft would be targeted for a postperihelion Halley intercept in March 1986 before proceeding toward an encounter with comet Tempel 2 in September 1988.

The study presents the statistical analysis of ozone sonde data obtained at Sodankyla (67.4 deg N, 26.6 deg E) from the beginning of the sounding program on March 1988 to the end of December 1991. The Sodankyla sounding data offers the longest continuous record of the ozone vertical distribution in the European Arctic. In this paper, we present the average ozone partial pressures within each 1 km column obtained for different seasons during the almost four year long period. We believe that the data represented here are useful as an interim reference ozone atmosphere, especially considering the fact that northern Scandinavia has become a popular campaign site for the big international ozone experiments.

The impact of cattle and goats grazing on vegetation in oak stands of varying coppicing age

Papachristou, Thomas G.; Platis, Panayiotis D.

2011-01-01

The effects of cattle and goats grazing on oak shoot growth and herbaceous vegetation in three oak forest stands with different coppicing age (1, 4 and 7 yrs after the clear cutting) were investigated. In April 1997, an experimental area was chosen with three forest stands, which were clear cut in 1996 (CL1996), 1993 (CL1993), and 1990 (CL1990). All stands were grazed by cattle and goats after they were clear cut. In each forest stand, five 10 m × 10 m paired plots were located, which represented grazed and protected patches. Herbage biomass within protected and grazed plots was measured four times each year (spring: May-June, summer: July-August, autumn: September-October, and winter: November-December). Behavioural observations on grazing animals were conducted in the same periods. In both protected and open plots the height and basal diameter of all oak shoots on 5 preselected stumps were measured at the end of five growing periods from 1997 to 2001. All forest stands carried a similar amount of available herbage (averaged over forest stands and growing season, 2614 kg/ha). Grazing animals removed on average 1057 kg/ha throughout the growing period. Cattle mainly consumed herbage (97% of bites) while goats consumed a mixture of oak browse (41% bites), herbaceous species (34% bites), and other woody species browse (25% bites). The height, diameter and volume of oak shoots were affected by grazing. The three forest stands had similar shoot heights in the protected plots in 2001 after 5 years of grazing protection. The volume of oak shoots of the grazed plots were 146.7 cm3 for CL1996, 232.9 cm3 for CL1993, and 239.1 cm3 for CL1990 in 2001 (i.e. 5, 8, and 11 years grazing after the clear cuttings, respectively). The protected plots carried greater volumes of oak shoots, CL1996: 496.0 cm3 (few months grazing before protection), CL1993: 690.0 cm3 (4 years grazing before protection), and CL1990: 344.0 cm3 (7 years grazing before protection). In conclusion, almost half of the herbaceous vegetation was removed through grazing but it had no positive effect on the growth rate of oak shoots. It seems that goats, which selected almost half of their diet from oak shoots, are responsible for that relative negative growth of shoots. However, cattle grazed only herbs and may therefore control herbaceous vegetation.

Traumatic brain injury (TBI) is a major cause of disability, morbidity, and mortality. The effect of the acute respiratory distress syndrome and acute lung injury (ARDS/ALI) on in-hospital mortality after TBI remains controversial. To determine the epidemiology of ARDS/ALI, the prevalence of risk factors, and impact on in-hospital mortality after TBI in the United States. Retrospective cohort study of admissions of adult patients>18 years with a diagnosis of TBI and ARDS/ALI from 1988 to 2008 identified through the Nationwide Inpatient Sample. During the 20-year study period, the prevalence of ARDS/ALI increased from 2% (95% confidence interval [CI], 2.1%-2.4%) in 1988 to 22% (95% CI, 21%-22%) in 2008 (P<.001). ARDS/ALI was more common in younger age; males; white race; later year of admission; in conjunction with comorbidities such as congestive heart failure, hypertension, chronic obstructive pulmonary disease, chronic renal and liver failure, sepsis, multiorgan dysfunction; and nonrural, medium/large hospitals, located in the Midwest, South, and West continental US location. Mortality after TBI decreased from 13% (95% CI, 12%-14%) in 1988 to 9% (95% CI, 9%-10%) in 2008 (P<.001). ARDS/ALI-related mortality after TBI decreased from 33% (95% CI, 33%-34%) in 1988 to 28% (95% CI, 28%-29%) in 2008 (P<.001). Predictors of in-hospital mortality after TBI were older age, male sex, white race, cancer, chronic kidney disease, hypertension, chronic liver disease, congestive heart failure, ARDS/ALI, and organ dysfunctions. Our analysis demonstrates that ARDS/ALI is common after TBI. Despite an overall reduction of in-hospital mortality, ARDS/ALI carries a higher risk of in-hospital death after TBI.

The hip fracture incidence curve is shifting to the right

PubMed Central

2009-01-01

Background The number of hip fractures has doubled in the last 30–40 years in many countries. Age-adjusted incidence has been reported to be decreasing in Europe and North America, but is there a decreasing trend in all age groups? Patients and methods This population-based study included all hip-fracture patients over 50 years of age (a total of 2,919 individuals, 31% of whom were men) admitted to Umeå University Hospital, Sweden, from 1993 through 2005. Results The incidence of hip fracture declined between the periods 1993–1996 and 2001–2005: from 706 to 625 hip fractures per 105 women and from 390 to 317 hip fractures per 105 men. However, there was a 114% increase in the number of fractures in women aged 90 or older (12 and 25 hip fractures/year, respectively, in the two time periods). For the period 2001–05, women ≥ 90 years of age accounted for almost the same numbers of hip fractures as women aged 75–79 (27 fractures/year). The rate increased during this period, from 2,700 per 105 women to 3,900 per 105 women > 90 years. In men there were declining trends for both relative and absolute numbers. Interpretation Although age-adjusted incidence declined in the population > 50 years of age, absolute fracture rate and incidence increased in the very old. Women over 90 now have the same absolute number of hip fractures every year as women aged 75–79 years. There was a right-shift in hip fracture distribution towards the oldest old, probably due to an increased number of octo/nonagenarians, a new population of particularly frail old people that hardly existed earlier. Better health among septuagenarians may also have delayed the age at which fractures occurred. This changing pattern will strain orthopedic and geriatric resources even more. PMID:19916682

The Center for Space Construction (CSC) at University of Colorado at Boulder is one of eight University Space Engineering Research Centers established by NASA in 1988. The mission of the Center is to conduct research into space technology and to directly contribute to space engineering education. The Center reports to the Department of Aerospace Engineering Sciences and resides in the College of Engineering and Applied Sciences. The College has a long and successful track record of cultivating multi-disciplinary research and education programs. The Center for Space Construction represents prominent evidence of this record. The basic concept on which the Center was founded is the in-space construction of large space systems, such as space stations, interplanetary space vehicles, and extraterrestrial space structures. Since 1993, the scope of CSC research has evolved to include the design and construction of all spacecraft, large and small. With the broadened scope our research projects seek to impact the technological basis for spacecraft such as remote sensing satellites, communication satellites and other special-purpose spacecraft, as well as large space platforms. A summary of accomplishments, including student participation and degrees awarded, during the contract period is presented.

Hypothesis: conjugate vaccines may predispose children to autism spectrum disorders.

PubMed

Richmand, Brian J

2011-12-01

The first conjugate vaccine was approved for use in the US in 1988 to protect infants and young children against the capsular bacteria Haemophilus influenzae type b (Hib). Since its introduction in the US, this vaccine has been approved in most developed countries, including Denmark and Israel where the vaccine was added to their national vaccine programs in 1993 and 1994, respectively. There have been marked increases in the reported prevalence of autism spectrum disorders (ASDs) among children in the US beginning with birth cohorts in the late 1980s and in Denmark and Israel starting approximately 4-5 years later. Although these increases may partly reflect ascertainment biases, an exogenous trigger could explain a significant portion of the reported increases in ASDs. It is hypothesized here that the introduction of the Hib conjugate vaccine in the US in 1988 and its subsequent introduction in Denmark and Israel could explain a substantial portion of the initial increases in ASDs in those countries. The continuation of the trend toward increased rates of ASDs could be further explained by increased usage of the vaccine, a change in 1990 in the recommended age of vaccination in the US from 15 to 2 months, increased immunogenicity of the vaccine through changes in its carrier protein, and the subsequent introduction of the conjugate vaccine for Streptococcus pneumoniae. Although conjugate vaccines have been highly effective in protecting infants and young children from the significant morbidity and mortality caused by Hib and S. pneumoniae, the potential effects of conjugate vaccines on neural development merit close examination. Conjugate vaccines fundamentally change the manner in which the immune systems of infants and young children function by deviating their immune responses to the targeted carbohydrate antigens from a state of hypo-responsiveness to a robust B2 B cell mediated response. This period of hypo-responsiveness to carbohydrate antigens coincides with the intense myelination process in infants and young children, and conjugate vaccines may have disrupted evolutionary forces that favored early brain development over the need to protect infants and young children from capsular bacteria.

Lohrasbi, J.

Dose calculations for atmospheric radionuclide releases from the Hanford Site for calendar year (CY) 1992 were performed by Pacific Northwest Laboratory (PNL) using the approved US Environmental Protection Agency (EPA) CAP-88 computer model. Emissions from discharge points in the Hanford Site 100, 200, 300, 400, and 600 areas were calculated based on results of analyses of continuous and periodic sampling conducted at the discharge points. These calculated emissions were provided for inclusion in the CAP-88 model by area and by individual facility for those facilities having the potential to contribute more than 10 percent of the Hanford Site total ormore » to result in an impact of greater than 0.1 mrem per year to the maximally exposed individual (MEI). Also included in the assessment of offsite dose modeling are the measured radioactive emissions from all Hanford Site stacks that have routine monitoring performed. Record sampling systems have been installed on all stacks and vents that use exhaust fans to discharge air that potentially may carry airborne radioactivity. Estimation of activity from ingrowth of long-lived radioactive progeny is not included in the CAP-88 model; therefore, the Hanford Site GENII code (Napier et al. 1988) was used to supplement the CAP-88 dose calculations. When the dose to the MEI located in the Ringold area was calculated, the effective dose equivalent (EDE) from combined Hanford Site radioactive airborne emissions was shown to be 3.7E-03 mrem. This value was reported in the annual air emission report prepared for the Hanford Site (RL 1993).« less

2010-05-01

The aim of this retrospective cohort study was to examine whether exposure to early childhood protein-energy malnutrition (ECPEM) is related to worsened periodontal status in the permanent dentition during adolescence. A trained clinician/researcher examined the periodontal status of 96 persons aged 12-19 living in rural Haiti using WHO diagnostic criteria (Community Periodontal Index, WHO 1997). Malnutrition data of the study participants had been collected during the years 1988-1993 by a nongovernmental organization. We compared those who had been malnourished in early childhood, based on z-scores for anthropomorphic data collected during the first 5 years of life, with those who had not been malnourished, regarding mean Community Periodontal Index (CPI) score, controlling for age, sex, socioeconomic status, and smoking. Overall, 57.3% of the participants demonstrated a CPI score of 3 or greater in at least one sextant. ECPEM was independently and positively related to mean CPI score, when controlling for sex and smoking. More than half of these young Haitians demonstrated CPI scores of 3 or greater, and ECPEM was related to poorer periodontal status, as measured by CPI, in the permanent dentition.

Background and Purpose We previously reported increased incidence of ischemic stroke among both blacks and whites with diabetes, especially in those <55 years old. With rising prevalence of diabetes in the last decade, we revisit the impact of diabetes on stroke incidence in the same population (~1.3 million) 5 and 10 years later. Methods This is a population-based study. First ischemic strokes among African American and white residents of the 5-county Greater Cincinnati/Northern Kentucky region, ≥20 years old, for periods 7/1993 to 6/1994, 1999, and 2005, were included in this analysis. Incidence rates were adjusted for gender, race and age, as appropriate, to the 2000 US population. Results History of diabetes among first ischemic strokes was reported for 493/1,709 (28%) in 1993/94, 522/1,778 (29%) in 1999, and 544/1,680 (33%) in 2005. Risk ratios (95% CI) for rates of stroke in those with versus without diabetes for African Americans reduced significantly from 5.6 in 1993/94 to 3.2 in 2005; for whites the risk ratio remained stable at 3.8 in 1993/94 and 2005. However, risk ratios varied with age, with an overall 5- to 14-fold increased risk observed in those 20 to 65 years old. Conclusions Those with diabetes remain at greatly increased risk for stroke at all ages, especially <65 years, regardless of race. The rates and risk ratios for 1999 and 2005, while similar to those previously reported for the mid-1990s, take on increased significance, given the epidemic of diabetes and metabolic syndrome throughout the US and the world.

Background Obesity is one of the leading causes of global morbidity and mortality. Trends in educational inequalities in obesity prevalence among Mexican women have not been analysed systematically to date. Methods Data came from four nationally representative surveys (1988, 1999, 2006, and 2012) of a total of 51 220 non-pregnant women aged 20 to 49. Weight and height were measured during home visits. Education level (higher education, high school, secondary, primary or less) was self-reported. We analysed trends in relative and absolute educational inequalities in obesity prevalence separately for urban and rural areas. Results Nationally, age-standardised obesity prevalence increased from 9.3% to 33.7% over 25 years to 2012. Obesity prevalence was inversely associated with education level in urban areas at all survey waves. In rural areas, obesity prevalence increased markedly but there was no gradient with education level at any survey. The relative index of inequality in urban areas declined over the period (2.87 (95%CI: 1.94, 4.25) in 1988, 1.55 (95%CI: 1.33, 1.80) in 2012, trend p<0.001). Obesity increased 5.92 fold (95%CI: 4.03, 8.70) among urban women with higher education in the period 1988–2012 compared to 3.23 fold (95%CI: 2.88, 3.63) for urban women with primary or no education. The slope index of inequality increased in urban areas from 1988 to 2012. Over 0.5 M cases would be avoided if the obesity prevalence of women with primary or less education was the same as for women with higher education. Conclusions The expected inverse association between education and obesity was observed in urban areas of Mexico. The declining trend in relative educational inequalities in obesity was due to a greater increase in obesity prevalence among higher educated women. In rural areas there was no social gradient in the association between education level and obesity across the four surveys. PMID:24599098

We generated a time-series of ERS-1/2 and ENVISAT interferometric synthetic aperture radar (InSAR) images to study ground surface deformation at Seguam Island from 1992 to 2008. We used the small baseline subset (SBAS) technique to reduce artifacts associated with baseline uncertainties and atmospheric delay anomalies, and processed images from two adjacent tracks to validate our results. Seguam Island comprises the remnants of two late Quaternary calderas, one in the western caldera of the island and one in the eastern part of the island. The western caldera subsided at a constant rate of ~ 1.6 cm/yr throughout the study period, while the eastern caldera experienced alternating periods of subsidence and uplift: ~ 5 cm/year uplift during January 1993–October 1993 (stage 1), ~ 1.6 cm/year subsidence during October 1993–November 1998 (stage 2), ~ 2.0 cm/year uplift during November 1998–September 2000 (stage 3), ~ 1.4 cm/year subsidence during September 2000–November 2005 (stage 4), and ~ 0.8 cm/year uplift during November 2005– July 2007 (stage 5). Source modeling indicates a deflationary source less than 2 km below sea level (BSL) beneath the western caldera and two sources beneath the eastern caldera: an inflationary source 2.5–6.0 km BSL and a deflationary source less than 2 km BSL. We suggest that uplift of the eastern caldera is driven by episodic intrusions of basaltic magma into a poroelastic reservoir 2.5–6.0 km BSL beneath the caldera. Cooling and degassing of the reservoir between intrusions results in steady subsidence of the overlying surface. Although we found no evidence of magma intrusion beneath the western caldera during the study period, it is the site (Pyre Peak) of all historical eruptions on the island and therefore cooling and degassing of intrusions presumably contributes to subsidence there as well. Another likely subsidence mechanism in the western caldera is thermoelastic contraction of lava flows emplaced near Pyre Peak during several historical eruptions, most recently in 1977 and 1992–93.

Local hazards, in the years 1993-2010 were the main reason for the intervention of the State Fire Service units in the urban-rural commune Łęczna (the Lublin voivodeship). In the analyzed period, most of the risks caused traffic accidents, which accounted for approximately 24% of total interventions. Natural hazards have caused a total of more than 24% of all interventions SFC. The highest risk (each 8.5%) from natural phenomena was due to high winds (hurricanes, tornadoes) and the dangerous behavior of the animals. Heavy rainfall (5.5%) and flooding (1.5%) and lightning (0.1%) do not constitute a greater threat. More than 64% of the analyzed threats recorded in city Łęczna. Among the country diversity was not very high, and the most interventions were recorded in the Zofiówka (4.6%). The most frequently local hazards have occurred in the second half. July and August. In the weekly cycle were most burdened Saturday (17.9%) and Friday, between the hours of 15 to 19.

To evaluate the indications for and outcomes of repeat penetrating keratoplasty over a 7-year period and compare them to a similar study over the prior 6-year period at the same institution. Retrospective noncomparative case series. Two hundred twenty-three consecutive repeat corneal transplants performed by one of five corneal surgeons between 1989 and 1995 were studied. Reasons for primary and regraft failure, indications for the initial corneal graft, graft clarity, and best-corrected visual acuity were measured on each patient. Between 1989 and 1995, 16% (271 of 1689) of transplants performed by our cornea group were regrafts compared with 9% (165 of 1860) in the period from 1983 to 1988 (P < 0.01). The most common indications for penetrating keratoplasty before regraft were pseudophakic bullous keratopathy (27%, 61 of 223), failed graft (20%, 44 of 223), Fuchs' dystrophy (11%, 24 of 223), aphakic bullous keratopathy (9%, 21 of 223), keratoconus (8%, 17 of 223), and herpes simplex keratitis (6%, 14 of 223). Compared with the prior study period of 1983 to 1988, an increase was revealed in the incidence of failed graft (11% to 20%, P = 0.03), and a decrease was revealed in the incidence of aphakic bullous keratopathy (19% to 9%, P = 0.01). Of the 223 regrafts, 55 (25%) failed during the study period (range, 1 month to 7.5 years; mean 2.1 years). Eleven percent (6 of 55) of regraft failures occurred within 6 months, and 55% (30 of 55) failed within 18 months. Of the 150 regrafts with 2 years follow-up (mean, 3.9 years), 111 (74%) had clear grafts. A best-corrected visual acuity of 20/20 to 20/40 was achieved in 41% (46 of 111), 20/50 to 20/100 in 32% (36 of 111), 20/200 to 20/400 in 21% (23 of 111), and counting fingers to no light perception in 5% (6 of 111). Failed grafts are increasing as an indication for penetrating keratoplasty. Graft clarity and visual acuity results continue to be very good, supporting the use of repeat corneal transplantation.

Socioeconomic factors and mortality in emergency general surgery: trends over a 20-year period.

Armenia, Sarah J; Pentakota, Sri Ram; Merchant, Aziz M

Socioeconomic factors such as race, insurance, and income quartiles have been identified as independent risk factors in emergency general surgery (EGS), but this impact has not been studied over time. We sought to identify trends in disparities in EGS-related operative mortality over a 20-y period. The National Inpatient Sample was used to identify patient encounters coded for EGS in 1993, 2003, and 2013. Logistic regression models were used to examine the adjusted relationship between race, primary payer status, and median income quartiles and in-hospital mortality after adjusting for patients' age, gender, Elixhauser comorbidity score, and hospital region, size, and location-cum-teaching status. We identified 391,040 patient encounters. In 1993, Black race was associated with higher odds of in-hospital mortality (odds ratio [95% confidence interval]: 1.35 [1.20-1.53]) than White race, although this difference dissipated in subsequent years. Medicare, Medicaid, and underinsured patients had a higher odds of mortality than those with private insurance for the entire 20-y period; only the disparity in the underinsured decreased over time (1993, 1.63 [1.35-1.98]; 2013, 1.41 [1.20-1.67]). In 2003 (1.23 [1.10-1.38]) and 2013 (1.23 [1.11-1.37]), patients from the lowest income quartile were more likely to die after EGS than patients from the highest income quartile. Socioeconomic disparities in EGS-related operative morality followed inconsistent trends. Over time, while gaps in in-hospital mortality among Blacks and Whites have narrowed, disparities among patients belonging to lowest income quartile have worsened. Medicare and Medicaid beneficiaries continued to experience higher odds of in-hospital mortality relative to those with private insurance. Copyright © 2017 Elsevier Inc. All rights reserved.

Suicide trends in an expanding mental health service in Auckland.

PubMed

Argyle, Nick

2010-10-01

Suicide is a global health priority. It is important to analyse the effects of investment in mental health services on suicide rates. This paper presents and discusses recent changes in suicide rates and diagnostic mix among clients of the mental health service in Auckland during a time of service growth. Details of suicides among current clients were analysed for the years 1993 to 2006, comparing the periods 1993-1999 and 2000-2006. These periods were compared with the local population and national figures. The local population suicide rate decreased significantly with the rate among clients increasing slightly so the proportion occurring among clients increased (up to 31%). There was an increase in non-psychotic diagnoses. As access to services expands the proportion of suicides that occur in known clients will paradoxically increase. Service expansion may have contributed to the falling population suicide rate in Auckland.

To study changes in authorship, interval between acceptance and publication, and bibliographic references of original articles published in Revista Española de Enfermedades Digestivas (REED) between 1993 and 1998. This was a descriptive retrospective study of 359 original research articles published in REED between 1993 and 1998. The variables assessed were: number of authors (author/article index), interval between acceptance of the manuscript and publication in the journal, and degree of obsolescence of articles based on the age of the references cited (Burton-Kleber and Price indexes). The author/article index was 6.1, and increased from 5.9 in 1993 to 6.5 in 1998. The interval between acceptance and publication increased from 251 days to 436 days in this period (p < 0.0001). English was the language of publication used most commonly, followed by Spanish (10.7%). Citations to Spanish references decreased from 12.5% in 1993 to 8.7% in 1998. The half-life of articles was 7 years, and Price index was 41.5%. REED's bibliometric characteristics are similar to those of other national journals, but this study shows changes in bibliographic indicators from 1993 to 1998; increases in the number of authors per article, the interval to publication, the use of foreign references and the degree of obsolescence.

To determine whether a two tier universal infant hearing screening programme (population based risk factor ascertainment and universal distraction testing) lowered median age of diagnosis of bilateral congenital hearing impairment (CHI) >40 dB HL in Victoria, Australia. Comparison of whole population birth cohorts pre and post introduction of the Victorian Infant Hearing Screening Program (VIHSP). All babies surviving the neonatal period born in Victoria in 1989 (pre-VIHSP) and 1993 (post-VIHSP) were studied. (1) Pre-1992: distraction test at 7-9 months. (2) Post-1992: infants with risk factors for CHI referred for auditory brain stem evoked response (ABR) assessment; all others screened by modified distraction test at 7-9 months. Of the 1989 cohort (n = 63 454), 1.65/1000 were fitted with hearing aids for CHI by end 1995, compared with 2.09/1000 of the 1993 cohort (n = 64 116) by end 1999. Of these, 79 cases from the 1989 cohort (1.24/1000) and 72 cases from the 1993 cohort (1.12/1000) had CHI >40 dB HL. Median age at diagnosis of CHI >40 dB HL for the 1989 birth cohort was 20.3 months, and for the 1993 cohort was 14.2 months. Median age at diagnosis fell significantly for severe CHI but not for moderate or profound CHI. Significantly more babies with CHI >40 dB HL were diagnosed by 6 months of age in 1993 than in 1989 (21.7% v 6.3%). Compared to the six years pre-VIHSP, numbers aided by six months were consistently higher in the six years post-VIHSP (1.05 per 100 000 births versus 13.4 per 100 000 births per year). VIHSP resulted in very early diagnosis for more infants and lowered median age of diagnosis of severe CHI. However, overall results were disappointing.

Purpose To track the use of medicine and self-medication from infancy to adolescence. Methods All newborns in the city of Pelotas, Brazil, were monitored and enrolled in the 1993 Pelotas (Brazil) Birth Cohort Study. Subsamples of the cohort were visited at 1, 3, and 6 months and at 1 and 4 years of age. At 11 and 15 years of age, all cohort members were sought. In each of these visits, information on medicine use in the 15 days before the interview was collected. Two outcomes were analyzed: prevalence of medicine use and prevalence of self-medication. Results Prevalence of medicine use in the first year of life ranged from 52.0% to 68.6%. From 4 to 15 years of age, the prevalence decreased, ranging from 30.9% to 37.2%. At age 15, girls presented a 33% higher prevalence of medicine use than boys. The proportion of self-medication ranged from 12.4% to 29.0% and was higher in girls aged 11 and 15 years than boys of the same age. In all follow-up periods, use of medicines was significantly higher among children who used medicines in the earlier period. Prevalence of self-medication was higher among those who were self-medicated in the previous periods. Conclusions Tracking studies are important to public health because they can predict future behavior by analyzing past behavior, thus helping in designing preventive actions. In this study, previous use of medicines predicts future use, thus creating an opportunity to plan actions that promote the rational use of medicines. PMID:23283153

To characterize national trends in non-fatal BB/pellet gun related injury rates for persons aged 19 years or younger in relation to trends in non-fatal and fatal firearm related injury rates and discuss these trends in light of injury prevention and violence prevention efforts. The National Electronic Injury Surveillance System (NEISS) includes approximately 100 hospitals with at least six beds that provide emergency services. These hospitals comprise a stratified probability sample of all US hospitals with emergency departments. The National Vital Statistics System (NVSS) is a complete census of all death certificates filed by states and is compiled annually. National data on BB/pellet gun related injuries and injury rates were examined along with fatal and non-fatal firearm related injuries and injury rates. Non-fatal injury data for all BB/pellet gun related injury cases from 1985 through 1999, and firearm related injury cases from 1993 through 1999 were obtained from hospital emergency department records using the NEISS. Firearm related deaths from 1985 through 1999 were obtained from the NVSS. BB/pellet gun related injury rates increased from age 3 years to a peak at age 13 years and declined thereafter. In contrast, firearm related injury and death rates increased gradually until age 13 and then increased sharply until age 18 years. For persons aged 19 years and younger, BB/pellet gun related injury rates increased from the late 1980s until the early 1990s and then declined until 1999; these injury rates per 100 000 population were 24.0 in 1988, 32.8 in 1992, and 18.3 in 1999. This trend was similar to those for fatal and non-fatal firearm related injury rates per 100 000 which were 4.5 in 1985, 7.8 in 1993, and 4.3 in 1999 (fatal) and 38.6 in 1993 and 16.3 in 1999 (non-fatal). In 1999, an estimated 14 313 (95% confidence interval (CI) 12 025 to 16 601) cases with non-fatal BB/pellet gun injuries and an estimated 12 748 (95% CI 7881-17 615) cases with non-fatal firearm related injuries among persons aged 19 years and younger were treated in US hospital emergency departments. BB/pellet gun related and firearm related injury rates show similar declines since the early 1990s. These declines coincide with a growing number of prevention efforts aimed at reducing injuries to children from unsupervised access to guns and from youth violence. Evaluations at the state and local level are needed to determine true associations.

The Health Post of Corte de Pedra is located in a region endemic for American tegumentary leishmaniasis (ATL) in the Brazilian state of Bahia, and it treats 500–1,300 patients annually. To describe temporal changes in the epidemiology of ATL, we reviewed a random sample of 10% of patient charts (N = 1,209) from 1988 to 2008. There was a twofold increase in the number of cases over the 20-year period, with fluctuations in 10-year cycles. Patients were most frequently male, between the ages of 10 and 30 years, and engaged in agricultural labor; 4.3% of patients had mucosal disease, and 2.4% of patients had disseminated disease. Over the study period, the number of disseminated cases increased threefold, the proportion of cases in younger patients and agricultural workers decreased, and the proportion of patients residing in coastal areas increased. ATL is on the rise in Bahia, with a 10-year periodicity and evolving changes in epidemiology and manifestations of disease. PMID:22403312

Syncyamus aequus Lincoln & Hurley, 1981, an amphipod parasite reported for the first time in South African waters, is re-examined in order to clarify the taxonomic value of some morphological characters not described in detail in the original description and in the following records (Raga, 1988; Sedlak-Weinstein, 1991). Three females (two ovigerous) and six males were collected from two specimens of Stenella coeruleoalba (Meyen, 1833) stranded along the Central Thyrrenian coasts in 1988 and 1993. The amphipods fixed and stored in 70 degrees ethanol were cleared with lactophenol for examination. Drawings were made with the aid of a Leitz microscope drawing attachment. The specimens examined showed the presence of spines located on pereopods I and II, which were lacking in the original description of S. aequus. The authors had the opportunity to compare the specimens (male, female and ovigerous female) with the paratype (PEMK2g) deposited in the Natural History Museum of London. The present re-examination reveals a morphological homogeneity among the specimens collected in Italian waters, the paratype and the individuals recorded by Raga (1988), thus suggesting that they belong to the same species, having a broad geographical distribution. This is the first record of S. aequus in Italian waters.

2060 Chiron - CCD and electronographic photometry

1989-01-01

R-band observations conducted for 2060 Chiron using CCD photometry in November-December 1986 and March 1988 are discussed. While the 1986 observations exhibit neither periodic nor nonperiodic brightness changes ascribable to comet-like activity, the 1988 observations show an 0.6 + or - 0.1 mag brightening that confirms the Tholen et al. (1988) findings and is consistent with the 1978 electronographic photometry presented. The lightcurve amplitudes appear, however, to have remained unchanged from 1978 to 1988, and the image profiles from 1978 are indistinguishable from the stars in 1986 and 1988. It is suggested that Chiron has either been varying nonasteroidally of late, on a 1-2 month timescale, or its intrinsic brightness has been bistable over the past decade.

Water, bed sediment, and biota were sampled in streams from Butte to below Missoula as part of a program to characterize aquatic resources in the upper Clark Fork basin of western Montana. Water- quality data were obtained periodically at 16 stations during October 1993 through September 1994 (water year 1994); daily suspended-sediment data were obtained at six of these stations. Bed-sediment and biological data were obtained at 11 stations in August 1994. Sampling stations were located on the Clark Fork and major tributaries. The primary constituents analyzed were trace elements associated with mine tailings from historical mining and smelting activities. Water-quality data include concentrations of major ions, trace elements, and suspended sediment in samples collected periodically during water year 1994. Daily values of streamflow, suspended-sediment concentration, and suspended- sediment discharge are given for six stations. Bed- sediment data include trace-element concentrations in the fine and bulk fractions. Biological data include trace-element concentrations in whole-body tissue of aquatic benthic insects. Quality-assurance data are reported for analytical results of water, bed sediment, and biota. Statistical summaries of bed sediment, and biological data are provided for the period of record at each station since 1985.

1995-05-01

The authors report a 12 year record study of oxygen 18 isotope signals in a coral (Ningaloo Reef), which is situated so as to give an ideal measure of the sea-surface temperature variation of the local Leeuwin Current. This record consists of nearly weekly readings from 1981 to 1993, and brackets the period following the June 1991 eruption of Mt. Pinatubo. Extended study shows a strong correlation of sea-surface temperature on this coral with changes in the Western Pacific Warm Pool (WPWP), with a lag of 2.5 years. A distinct cooling signal was seen in the inferred sea-surface temperatures frommore » coral measurements, in 1992 and 1993, which suggests the WPWP was cooled roughly 0.5{degrees}C by aerosol induced effects.« less

Recovery of the coral Montastrea annularis in the Florida Keys after the 1987 Caribbean ``bleaching event''

NASA Astrophysics Data System (ADS)

Fitt, William K.; Spero, Howard J.; Halas, John; White, Michael W.; Porter, James W.

1993-07-01

Many reef-building corals and other cnidarians lost photosynthetic pigments and symbiotic algae (zooxanthellae) during the coral bleaching event in the Caribbean in 1987. The Florida Reef Tract included some of the first documented cases, with widespread bleaching of the massive coral Montastrea annularis beginning in late August. Phototransects at Carysfort Reef showed discoloration of >90% of colonies of this species in March 1988 compared to 0% in July 1986; however no mortality was observed between 1986 and 1988. Samples of corals collected in February and June 1988 had zooxanthellae densities ranging from 0.1 in the most lightly colored corals, to 1.6x106 cells/cm2 in the darker corals. Minimum densities increased to 0.5x106 cells/cm2 by August 1989. Chlorophyll- a content of zooxanthellae and zooxanthellar mitotic indices were significantly higher in corals with lower densities of zooxanthellae, suggesting that zooxanthellar at low densities may be more nutrientsufficient than those in unbleached corals. Ash-free dry weight of coral tissue was positively correlated with zooxanthellae density at all sample times and was significantly lower in June 1988 compared to August 1989. Proteins and lipids per cm2 were significantly higher in August 1989 than in February or June, 1988. Although recovery of zooxanthellae density and coral pigmentation to normal levels may occur in less than one year, regrowth of tissue biomass and energy stores lost during the period of low symbiont densities may take significantly longer.

Decreasing trends in cardiovascular mortality in Turkey between 1988 and 2008

PubMed Central

2013-01-01

Background Cardiovascular disease (CVD) mortality increased in developed countries until the 1970s then started to decline. Turkey is about to complete its demographic transition, which may also influence mortality trends. This study evaluated trends in coronary heart disease (CHD) and stroke mortality between 1988 and 2008. Methods The number of deaths by cause (ICD-8), age and sex were obtained from the Turkish Statistical Institute (TurkStat) annually between 1988 and 2008. Population statistics were based on census data (1990 and 2000) and Turkstat projections. European population standardised mortality rates for CHD and stroke were calculated for men and women over 35 years old. Joinpoint Regression was used to identify the points at which a statistically significant (p < 0.05) change of the trend occurred. Results The CHD mortality rate increased by 2.9% in men and 2.0% in women annually from 1988 to 1994, then started to decline. The annual rate of decline for men was 1.7% between 1994–2008, whilst in women it was 2.8% between 1994–2000 and 6.7% between 2005–2008 (p < 0.05 for all periods). Stroke mortality declined between 1990–1994 (annual fall of 3.8% in both sexes), followed by a slight increase between 1994–2004 (0.6% in men, 1.1% in women), then a further decline until 2008 (annual reduction of 4.4% in men, 7.9% in women) (p < 0.05 for all periods). Conclusions A decrease in CVD mortality was observed from 1995 onwards in Turkey. The causes need to be explored in detail to inform future policy priorities in noncommunicable disease control.

With the advancement of microsurgical techniques, lamellar keratoplasty (LK) has been more valued and performed to treat corneal blindness. This study aimed to evaluate the indications and changing trends for LK during the past 16 years in Shandong Eye Institute, an eye center in China. A total of 1529 eyes, predominantly from male (70.7%) patients undergoing LK between January 1993 and December 2008, were enrolled in this study. Data were collected by reviewing patient medical records for demographic characteristics, clinical diagnosis, laboratory findings and risk factors. Surgical times, initial diagnoses and causes of regrafting were recorded. All LKs were sequentially divided into period 1 (from 1993 to 2000) and period 2 (from 2001 to 2008). Rural-dwelling patients in this study numbered 1089 (71.2%); in all cases of infectious keratitis, rural patients accounted for 90.5%. The leading indications for LK were infectious keratitis (31.0%), corneal trauma (21.1%), keratoconus (18.7%), corneal dystrophy and degeneration (7.3%), regrafting (7.1%), immunologic disorders (6.7%), congenital abnormalities and corneal tumor (4.1%) and corneal scarring (3.1%). The most common subcategory of infectious keratitis was fungal keratitis (67.5%). Fusarium solani was the most morbigenous fungi. Among the patients, 73.1% of thermal burns were caused by hot molten metal, and 47.8% of alkali burns by lime. Dermoid was the most common indication for congenital abnormalities. The two main initial diagnoses from 109 regrafting cases were corneal trauma (45.9%) and Mooren's ulcer (27.5%). The most common cause for regrafting was immune rejection (35.8%). Infectious keratitis was the most common indication for LK from 16.0% in period 1 to 41.1% in period 2, followed by keratoconus (16.8%) and corneal trauma (14.5%). During the past 16 years, there have been major changes in the constituent ratios of leading indications for LK in Shangdong. Infectious keratitis has become the most common indication for LK. Fungal keratitis was the most common subcategory of infectious keratitis.

The EPA criteria air pollutants were monitored at Kennedy Space Center (KSC) since 1983 to comply the prevention of significant deterioration requirements under the Clean Air Act amendments passed by Congress in 1977 and 1990. Monitoring results show that monthly maximum 24-hour total suspended particulates decreased from 144.6 micograms/cu m in 1988 to 73.0 micrograms/cu m in 1991 and increased to 149.3 micrograms/cu m in 1992. Inhalable particulates increased from 56.1 gg/M3 in 1983 to 131.4 micrograms/cu m in 1988, and then decreased to 38.5 micrograms/cu m in 1992. Sulfur dioxide monthly maximum 24-hour average concentrations decreased each year from 135.2 micrograms/cu m in 1983 to 33.8 micrograms/cu m in 1992. Nitrogen dioxide concentrations increased from 5.1 micrograms/cu m in 1983 to 5.9 micrograms/cu m in 1988, then decreased to 4.5 micrograms/cu m in 1992. Carbon monoxide annual average concentrations decreased from 6.2 micrograms/cu m in 1983 to 1.1 micrograms/cu m in 1988, and increased to 1.2 micrograms/cu m in 1992. Ozone maximum 1-hour concentrations increased from 98 parts per billion (ppb) in 1983 to 134 ppb in 1989, and then decreased to 80 ppb in 1992. Total annual rainfall ranged from 37.47 inches to 57.47 inches and shows a 6.6 percent increase over this same ten year period.

Few data are available to describe the changes in incidence of pediatric-onset inflammatory bowel disease (IBD). The aim of this study was to describe changes in incidence and phenotypic presentation of pediatric-onset IBD in northern France during a 24-year period. Pediatric-onset IBD (<17 years) was issued from a population-based IBD study in France between 1988 and 2011. Age groups and digestive location were defined according to the Paris classification. 1,350 incident cases were recorded (8.3% of all IBD) including 990 Crohn's disease (CD), 326 ulcerative colitis (UC) and 34 IBD unclassified (IBDU). Median age at diagnosis was similar in CD (14.4 years (Q1=11.8-Q3=16.0)) and UC (14.0 years (11.0-16.0)) and did not change over time. There were significantly more males with CD (females/males=0.82) than UC (females/males=1.25) (P=0.0042). Median time between onset of symptoms and IBD diagnosis was consistently 3 months (1-6). Mean incidence was 4.4/10 5 for IBD overall (3.2 for CD, 1.1 for UC and 0.1 for IBDU). From 1988-1990 to 2009-2011, a dramatic increase in incidences of both CD and UC were observed in adolescents (10-16 years): for CD from 4.2 to 9.5/10 5 (+126%; P<0.001) and for UC, from 1.6 to 4.1/10 5 (+156%; P<0.001). No modification in age or location at diagnosis was observed in either CD or UC. In this population-based study, CD and UC incidences increased dramatically in adolescents across a 24-year span, suggesting that one or more strong environmental factors may predispose this population to IBD.

The F- and H-Area Seepage Basins received liquid waste from the F and H chemical separation facilities from 1955 through 1988. Tree mortality in seepline fed wetlands down-slope from the basins was observed in the late 1970`s, and investigations were conducted to determine the cause and source of the impacts. Analysis of the soil and water in the tree-kill zones demonstrated a strong chemical linkage with the F- and H-Area seepage basins. Although no single cause of the mortality was determined, it was believed to be the result of interactions of alterations in the hydrology and erosional deposition, along withmore » lowering of pH and increased conductivity, sodium, aluminum, and nitrogen compounds. A mild drought during the growing season may also have increased the concentration of the chemical contaminants in the soils matrix. In 1988, the F- and H-Area Seepage Basins were closed and covered with a clay cap to reduce the rate of dispersion of the contaminants in the soil beneath the basins. Subsequent studies of the chemical composition of the tree-kill zone groundwater and toxicological characteristics of the seepline soil have shown a reduced contaminant flux. In 1993, an initial vegetation study was undertaken to determine the level of recovery by the plant communities in the tree-kill zones. This study repeats the initial vegetation investigation in order to further analyze and characterize the recovery of plant communities in the zones after an additional year of growth.« less

Assessing habitat use by breeding great blue herons (Ardea herodias) on the upper Mississippi River, USA

Kirsch, E.M.; Ickes, B.; Olsen, D.A.

2008-01-01

Approximately 7,610 to 3,175 pairs of Great Blue Herons (Ardea herodias) nested along 420 river km of the Uppert Mississippi River (UMR) from 1993 to 2003. Numbers declined precipitously in the mid-1990s stabilizing somewhat in the early 2000s. The average number of nests in colonies was 349 (SD = 283). Annual colony turn over rate for the eleven year period was 0.15 and ranged from 0.06 to 0.29 each year. The number of years that a colony was active was positively correlated with the average number of nests present while the colony was active. Of the eight colonies active in 1993 that averaged more than 349 nests, four were abandoned by 2003. Only one colony grew to greater than 349 nests during the study period. Custer et al. (2004) suggested that herons on the UMR may be limited by forage resources or foraging habitat and social factors, as evidenced by the even spacing of colonies that reflects the maximum feeding range of herons on the river. To rule out nesting and foraging habitat limitation, landscape habitat features of terrestrial and aquatic areas were examined for colony areas and areas without colonies. Available fish monitoring data were used to examine potential interactions between herons and forage resources. Colony areas did not differ from areas without colonies in any habitat feature. Indices of potential heron forage fish increased from 1993 to 2002, although low indices of fish abundance in 1993 were likely influenced by flood conditions that year. Although fish availability to herons is related to flows and water levels, available data suggested that herons did not negatively impact their potential forage base. Numbers of herons were not correlated with indices of fish abundance from the preceding year on a pool-wide scale. Indices of fish abundance were higher within 5 km of colonies than farther than 5 km from colonies, and indices of fish abundance increased from June through August both near and far from colonies. Numbers of herons and locations and sizes of colonies varied annually, whereas landscape features typically vary little if at all from year to year. Indices of fish abundance also varied greatly by sample location and year. Disturbance, particularly by humans in this highly used river, should be examined in relation to limiting foraging opportunities and influencing behavior (colony and individual) and productivity in colonies.

Median PCB concentrations in common carp and walleye at individual sites were greatest during 1975-79 and 1980-87, and least during 1988-95 at most sites. Most of the river segments exhibited over 80 percent decline in median PCB concentrations in common carp and walleye between the 1975-79 and 1988-95 time periods. The results from these temporal analyses were similar to those of other studies in the United States and in Minnesota and Wisconsin that reported a significant downward trend in PCB concentrations in fish. Although, PCB concentrations have decreased during 1975-95, low concentrations of PCBs still remain in the aquatic environment despite the fact that PCBs were banned nearly 20 years ago.

Wind and waves are key components of the climate system as they drive air-sea interactions and influence weather systems and atmospheric circulation. In marine environments, understanding surface wind and wave fields and their evolution over time is important for conducting safe and efficient human activities, such as navigation and engineering. This study considers long-term trends in the sea surface wind speed (WS) and significant wave height (SWH) in the China Seas over the period 1988-2011 using the Cross-Calibrated Multi-Platform (CCMP) ocean surface wind product and a 24-year hindcast wave dataset obtained from the WAVEWATCH-III (WW3) wave model forced with CCMP winds. The long-term trends in WS and SWH in the China Seas are analyzed over the past 24 years to provide a reference point from which to assess future climate change and offshore wind and wave energy resource development in the region. Results demonstrate that over the period 1988-2011 in the China Seas: 1) WS and SWH showed a significant increasing trend of 3.38 cm s-1 yr-1 and 1.52 cm yr-1, respectively; 2) there were notable regional differences in the long-term trends of WS and SWH; 3) areas with strong increasing trends were located mainly in the middle of the Tsushima Strait, the northern and southern areas of the Taiwan Strait, and in nearshore regions of the northern South China Sea; and 4) the long-term trend in WS was closely associated with El Niño and a significant increase in the occurrence of gale force winds in the region.

Solar wind plasma periodicities observed at 1 AU by IMP 8

NASA Technical Reports Server (NTRS)

Paularena, K. I.; Szabo, A.; Lazarus, A. J.

1995-01-01

The IMP 8 spacecraft has been in Earth orbit since 1973, gathering plasma data over one complete 22-year solar cycle. These data are being examined to look for periodicities at time scales ranging from several hours to the entire span of the data set. A 1.3-year periodicity in the radial speed observed by IMP 8 and Voyager 2 has already been reported for the years from 1987 to 1993. The periodogram method, useful for unevenly sampled data such as the IMP 8 plasma data, has been used to search for other periods. It is interesting to note that the 13-year period is not present in the out-of-the-ecliptic component of the velocity (Vz), although a 1-year period is very obvious both visually and on the periodogram. Both components show a very strong peak associated with the 11-year solar cycle variation. This work will be extended to the thermal speed (a measure of the wind's temperature) and density, although the frequent correlations between these parameters and the velocity are expected to cause similar results. Additionally, the fine resolution data will be examined for shorter time periods than are visible using the hourly average data which are appropriate for longer periods. A comparison with periods observed at other spacecraft may also be made.

Metabolic syndrome is a cluster of cardiometabolic risk factors associated with increased risk of multiple chronic diseases, including cancer and cardiovascular disease. The objectives of this study were to estimate the prevalence of metabolic syndrome overall, by race and sex, and to assess trends in prevalence from 1988 through 2012. We analyzed data from the National Health and Nutrition Examination Survey (NHANES) for 1988 through 2012. We defined metabolic syndrome as the presence of at least 3 of these components: elevated waist circumference, elevated triglycerides, reduced high-density lipoprotein cholesterol, high blood pressure, and elevated fasting blood glucose. Data were analyzed for 3 periods: 1988-1994, 1999-2006, and 2007-2012. Among US adults aged 18 years or older, the prevalence of metabolic syndrome rose by more than 35% from 1988-1994 to 2007-2012, increasing from 25.3% to 34.2%. During 2007-2012, non-Hispanic black men were less likely than non-Hispanic white men to have metabolic syndrome (odds ratio [OR], 0.77; 95% confidence interval [CI], 0.66-0.89). However, non-Hispanic black women were more likely than non-Hispanic white women to have metabolic syndrome (OR, 1.20; 95% CI, 1.02-1.40). Low education level (OR, 1.56; 95% CI, 1.32-1.84) and advanced age (OR, 1.73; 95% CI, 1.67-1.80) were independently associated with increased likelihood of metabolic syndrome during 2007-2012. Metabolic syndrome prevalence increased from 1988 to 2012 for every sociodemographic group; by 2012, more than a third of all US adults met the definition and criteria for metabolic syndrome agreed to jointly by several international organizations.

We estimated seasonal and annual survival rates of cackling Canada geese (Branta canadensis minima ) for the period 1982-1989 to identify periods of high mortality and assess effects of harvest management decisions. We tested hypotheses about age- and sex-specific variation in survival, seasonal variation in survival rates, and variation in survival between years in which hunting seasons were open and closed. Geese were marked with individually identifiable neckbands and observed from autumn through spring. We used these data to estimate survival rates for 3-month periods in early (EW) and late (LW) winter and a 6-month period in summer (SU). Mean annual survival rates of immature females were lower than those of adults over the entire study. Survival rates of immature males were lower than those of adults during the 2 years with sport hunting seasons. We found no evidence of sex-specific differences in seasonal or annual survival rates of immature geese.

The double stellar occultation by Pluto and Charon of 2011 June 23 was observed from numerous ground stations as well as the Stratospheric Observatory for Infrared Astronomy (SOFIA). This first airborne occultation observation since 1995 resulted in the best occultation chords recorded for the event, in three optical wavelength bands. The data obtained from SOFIA were combined with chords obtained from the ground at the IRTF (including a full spectral light curve), the USNO--Flagstaff Station, and Leeward Community College to give a detailed profile of Pluto’s atmosphere. The data show a return to the distinct upper and lower atmospheric regions with a knee, or kink in the light curves separating them as was observed in 1988 (Millis et al. 1993), rather than the smoothly transitioning bowl-shaped light curves of recent years (Elliot et al. 2007). We analyze the upper atmosphere by fitting a model to all of the light curves obtained, resulting in a half-light radius of 1288 ± 1 km. We analyze the lower atmosphere with two different methods to provide results under the separate assumptions of particulate haze and a strong thermal gradient. Results indicate that the lower atmosphere evolves on short seasonal timescales, changing between 1988 and 2006, and then returning to approximately the 1988 state in 2011, though at significantly higher pressures. Throughout these changes, the upper atmosphere remains remarkably stable in structure, again excepting the overall pressure changes. No evidence of the onset of atmospheric collapse predicted by frost migration models is yet seen, and the atmosphere appears to be remaining at a stable pressure level. This work was supported in part by NASA Planetary Astronomy grants to MIT (NNX10AB27G) and Williams College (NNX08AO50G, NNH11ZDA001N), as well as grants from USRA (#8500-98-003) and Ames Research (#NAS2-97-01) to Lowell Observatory.

During implantation of a DDD pacemaker the following difficulties may be encountered: venous anomalies (the absence of vessels of adequate calibre or difficulty in subclavian vein puncture), arrhythmias during implantation (episodes of atrial flutter/fibrillation while the atrial leads are being positioned), lack of mechanical stability of the electrode in the heart chamber and inability to achieve an acceptable pacing and sensing threshold during implantation. The purpose of the study was to analyse retrospectively the reasons for DDD pacemaker failure in patients operated on between 1993 and 2005. We reviewed retrospectively all implantation data from 1988 to 2005 to identify patients with primary failure of DDD pacemaker implantation. Further analysis included patients who had received a DDD pacemaker between 1993 and 2005, when this type of pacemaker made up between 9 and 40% of all pacemaker implantations. We implanted 7469 pacemakers, including 1958 (26.2%) dual-chamber pacemakers, in 783 patients with atrioventricular block (AVB), 392 with sick sinus syndrome (SSS), 450 with AVB +/- SSS and 333 with tachy-brady syndrome (TBS). The mean age of the patients was 65.5 +/- 17.3 years. DDD pacing was unsuccessful in 108 (1.4%) patients, including 32 with AVB, 22 with SSS, 16 with SSS +/- AVB and 38 with TBS. The mean age of these patients was 78.5 +/- 19.4 years. The reasons for failed implantation were venous anomalies in 12%, an arrhythmia episode in 27.8%, a high pacing threshold in the atrium in 17.6%, low atrial potential amplitude in 25.9% and lack of mechanical stability of the electrode in 16.7% of patients. The difficulties were encountered in elderly patients (p < 0.01), most frequently in patients with SSS and TBS (71). Between 2004 and 2005 venous anomalies and a high pacing threshold were the main causes of failure. Currently the main difficulties encountered during pacemaker implantation are venous anomalies and a high pacing threshold. Arrhythmia episodes, low atrial potential amplitude and lack of mechanical stability are of minor importance. Elderly patients with sick sinus syndrome and tachy-brady syndrome have the highest failure rate. (Cardiol J 2007; 14: 155-159).

[Multiresistant tuberculosis in Denmark 1993-1996].

PubMed

Viskum, K; Kok-Jensen, A

1998-05-18

Infections with multiresistant tubercle bacilli have also become a problem in the rich part of the world. The reasons are lack of compliance in patients with life style problems and ineffectiveness of the health system due to lack of fundings. During a four year period, 1993-1996 ten patients were seen in Denmark with tuberculosis due to multiresistant Mycobacterium tuberculosis. Nine were infected abroad, one developed MDR-TB during treatment in Denmark. It is possible to cure these patients, but it is expensive and takes a long time. In the future more cases created within Denmark are likely to be seen due to lack of funding for the tuberculosis programme and, depending on immigration, further cases created abroad are expected.

Approximately 98% of Danish citizens are listed with a general practice which they consult for medical advice. Although 85% of the population contact their general practitioner (GP) every year, little is known about these contacts. The aim of the present paper is to gain updated knowledge about patients' reasons for encounter and the GP activities and to make comparisons with a similar study from 1993. All GPs in the Central Denmark Region were invited to register all contacts during one randomly chosen day within a year. The registration included questions about patients' reasons for encounter, the types and contents of the contacts, referrals, and distribution between new episodes and follow-up contacts. Aggregated data were compared with the results from 1993. A total of 404 (46%) GPs participated. The number of contacts per 1000 inhabitants had risen by 19.7%. The reasons for encounter and final diagnoses resembled those in 1993. Musculoskeletal, psychological, and respiratory problems were the most common reasons for encounter, psychological problems being the only type to increase over the period. Interestingly, the proportion of diagnoses within the ICPC 'A' chapter rose from 13.5 to 19.7%. The referral rate rose by 2% (relative: 18.7%) from 10.7% to 12.7% and the share of follow-up contacts rose from 45.9% to 50.4% (relative: 8.7%). Quite small changes were seen in the patterns of reasons for encounter and diagnoses from 1993 to 2009. However, an increase was found in contacts with general practice and referrals and in the proportion of follow-ups.

Dietary studies of children: the Bogalusa Heart Study experience.

PubMed

Nicklas, T A

1995-10-01

For more than 20 years the Bogalusa Heart Study has been collecting data on children's dietary intakes in a biracial community. The macronutrient contribution of children's diets is similar to that in diets of adolescents: 13% of energy from protein, 49% from carbohydrate, and 38% from fat. As children get older, mean intakes of vitamins and minerals per 1,000 kcal decrease. Ten-year-old children in 1987-1988 were 3 lb heavier than 10-year-olds in 1973-1974. Yet total energy intakes remained virtually the same from 1973 to 1988. The composition of macronutrients shifted over the 15-year period, with an increase in the percentage of energy from protein and carbohydrate and a decrease in the percentage of energy from total fat, particularly saturated fat. Dietary cholesterol intake also decreased as a result of a decrease in egg consumption. Although the diets of children changed positively from 1973 to 1988, more than 75% of children consumed more total fat, saturated fat, and cholesterol than the recommended amounts. School meals had a major impact on the diets of children. School breakfast and lunch, together, contributed approximately 50% of the day's total intake of energy, protein, cholesterol, carbohydrate, and sodium. About 40% of daily total fat intake came from school breakfast and lunch. The diets of children in the Bogalusa study are similar to those reported in national studies of children. What might be different, however, are the types of foods consumed and their contribution to intakes of specific nutrients.(ABSTRACT TRUNCATED AT 250 WORDS)

Water-use efficiency of willow: Variation with season, humidity and biomass allocation

1994-04-01

Information on the water-use efficiency (WUE) of a vegetation cover improves understanding of the interrelationship between the water and carbon cycles, and enables hydrological practices to be related to agricultural and silvicultural planning and management. This study determined seasonal and climatic variations of the WUE of a fertilized and irrigated short-rotation stand of Salix viminalis L. on a clay soil. The WUE was determined as the ratio of above-ground production to transpiration or, alternatively, to transpiration divided by the saturation vapour pressure deficit. Growth was estimated from a combination of destructive and non-destructive measurements for 10 day periods during the growing seasons of 1986 and 1988. Daily transpiration was estimated using a physically based evaporation model, tuned against energy-balance/Bowen-ratio measurements of total stand evaporation. Nutrients were adequate and climate conditions were similar in both years. In spite of irrigation soil-water deficits developed during midsummer and affected growth rates in different ways: in 1986, both stem and leaf growth decreased, while in 1988 only stem growth decreased. Exceptionally high stem growth rates, twice the total potential growth rates, were recorded after the drought of 1988. They were probably caused by root-allocated assimilates that were sent above-ground after the drought. In both years, stem growth ceased 2-3 weeks after the leaf area had reached its maximum. Since light and temperature were still sufficient to maintain assimilation, all growth presumably took place below ground towards the end of the season. Changes in root-shoot allocation caused large variations in the WUE in 1988. The WUE, weighted by the saturation vapour pressure deficit, was fairly constant in 1986. In both years, the WUE was correlated with the vapour pressure deficit. Towards the end of both growing seasons, when all assimilates were sent below ground, the WUE decreased rapidly to zero. The total WUE, estimated as the seasonally accumulated above-ground production divided by accumulated transpiration, was 4.1 g kg -1 in 1986 and 5.5 g kg -1 in 1988, which is relatively high in comparison with other species.

Objectives We investigated whether associations between nativity/length of US residence and body mass index (BMI) and waist circumference (WC) varied over the past two decades. Methods Mexican-Americans aged 20–64 years from the National Health and Nutrition Survey (NHANES) III (1988–1994), and NHANES (1999–2008). Sex-stratified multivariable linear regression models further adjusted for age, education, and NHANES period. Results We found no evidence of secular variation in the nativity/length of US residence gradient for men or women. Foreign-born Mexican-Americans, irrespective of residence length, had lower mean BMI and WC than their US-born counterparts. However among women, education modified secular trends in nativity differentials: notably, in less-educated women, nativity gradients widened over time due to alarming increases in BMI among the US-born and little increase in the foreign-born. Conclusions Associations between nativity/length of US residence and BMI/WC did not vary over this 20-year period, but we noted important modifications by education in women. Understanding these trends is important for identifying vulnerable subpopulations among Mexican-Americans and for the development of effective health promotion strategies in this fast-growing segment of the population.

Aerial surveys of manatees conducted since 1977 at Kennedy Space Center (KSC) have provided a very useful and cost effective monitoring tool in the assessment of abundance and distribution of manatees in the northern Banana River. Data collected in the mid 1980's as part of the KSC Environmental Monitoring Program indicated that the numbers of manatees utilizing the northern Banana River had increased dramatically from earlier years and that the animals appeared to have changed their distribution patterns within the area as well (Provancha and Provancha 1988). United States Fish and Wildlife Service (USFWS) and Florida Department of Natural Resources (FLDNR) conducted bimonthly aerial surveys in 1986 for the entire Florida east coast. Their data clearly show that the Banana River has the highest concentration of manatees during the non-winter months when compared to all other segments of the east coast surveys (B. Wiegle/FLDNR, unpublished data). They further show that, in spring, an average of 71 percent of the manatees in Brevard county were located in the Banana River. During that period 85 percent of the animals were north of the NASA Causeway (State Road (SR) 402) in the KSC security zone. These data indicate the importance of the KSC waters to the Florida east coast manatee population. We reinitiated KSC surveys in 1987 to document distributions and numbers of manatees during the spring influx. Aerial censuses were continued throughout the year in 1988 and this report provides a summary of our findings for the two years.

Adolescents and young adults (AYA) surviving classical Hodgkin lymphoma (cHL) risk long term fatal treatment-related toxicities. We utilized the Surveillance, Epidemiology and End Results (SEER) program to compare excess mortality rate (EMR-observed minus expected mortality) for 10-year survivors of AYA cHL diagnosed in 1973-1992 and 1993-2003 eras. The 15-year EMR reduced from 4.88% to 2.19% while the 20-year EMR reduced from 9.46% to 4.07% between eras. Survivors of stages 1-2 had lower EMR than survivors of stages 3-4 cHL in the 1993-2003 but not in the 1973-1992 era. There was an overall decline in risk of death between 10 and 15 years from diagnosis, driven mostly by second neoplasms and cardiovascular mortality. Despite reduction in fatal second neoplasms and cardiovascular disease with more current therapy, long term survivors of AYA cHL still have a higher risk of death than the general population highlighting the need for safer therapies. © 2017 Wiley Periodicals, Inc.

Glioma is a heterogeneous central nervous system (CNS) tumor group that encompasses different histological subtypes with high variability in prognosis. The lesions account for almost 80% of primary malignant brain tumors. The aim of this study is to extend our understanding of the glioma epidemiology in the central Tunisian region. We analyzed 393 gliomas recorded in cancer registry of central Tunisia from 1993 to 2012. Crude incidence rates (CR) and world age-standardized rates (ASR) were estimated using annual population data size and age structure. Statistic correlations were established using Chi-square and Kaplan-Meier test. Tunisian glioma patients were identified with a mean age at diagnosis of 48 years and 1.5 sex ratio (male/female). During the 19 years period of study the highest incidence value was observed in male group between 1998 and 2002 (CR: 0.28, ASR: 0.3). Incidence results underline increasing high grade glioma occurring in the adulthood in the last period (2007-2012). Median survival was 27 months, with 1-, 2- and 5-year survival rates of 42%, 30% and 26%, respectively. Survival was greater in patients with younger age, lower tumor grade, infratentrial tumor location and undergoing a palliative treatment. This central Tunisia gliomas registry study provides important information that could improve glioma management and healthcare practice.

National and local declines in lead (Pb) in blood (PbB) over the past several years coincide with the decline in ambient air Pb (PbA) concentrations. The objective of this work is to evaluate how the relationship between PbB levels and PbA levels has changed following the phase out of leaded gasoline and tightened controls on industrial Pb emissions over the past 30 years among a national population sample. Participant-level data from the National Health and Nutrition Examination Survey (NHANES) were employed for two time periods (1988-1994 and 1999-2008), and the model was corrected for housing, demographic, socioeconomic, and other covariates present in NHANES. NHANES data for PbB and covariates were merged with PbA data from the U.S. Environmental Protection Agency. Linear mixed effects models (LMEs) were run to assess the relationship of PbB with PbA; sample weights were omitted, given biases encountered with the use of sample weights in LMEs. The 1988-1994 age-stratified results found that ln(PbB) was statistically significantly associated with ln(PbA) for all age groups. The consistent influence of PbA on PbB across age groups for the years 1988-1994 suggests a ubiquitous exposure unrelated to age of the sample population. The comparison of effect estimates for ln(PbA) shows a statistically significant effect estimate and ANOVA results for ln(PbB) for the 6- to 11-year and 12- to 19-year age groups during 1999-2008. The more recent finding suggests that PbA has less consistent influence on PbB compared with other factors. Copyright © 2013 Elsevier B.V. All rights reserved.

Potentiometric Surfaces and Changes in Groundwater Levels in Selected Bedrock Aquifers in the Twin Cities Metropolitan Area, March-August 2008 and 1988-2008

This report depicts potentiometric surfaces and groundwater- level changes in three aquifers that underlie the seven-county Twin Cities Metropolitan Area. Approximately 350 groundwater levels were measured in wells from the three aquifers-the Prairie du Chien-Jordan, the Franconia-Ironton-Galesville, and the Mount Simon-Hinckley aquifers-in March and August of 2008. The report presents maps, associated data tables, and 22 geographic information system datasets. The maps presented in this report show the potentiometric surfaces in March and August of 2008 for all three aquifers, groundwater-level changes from March to August 2008 for each aquifer, and revised potentiometric-surface contours for the winter of 1988-89 for the Prairie du Chien-Jordan and the Mount Simon-Hinckley aquifers, and the estimated long-term (winter of 1988-89 to March 2008) groundwater-level changes for the Prairie du Chien-Jordan and Mount Simon-Hinckley aquifers. This report documents the methods used to construct the maps and provides a context for the period of the measurements. Although withdrawal demand is increasing in the Twin Cities Metropolitan area, particularly in the Prairie du Chien-Jordan aquifer, year-to-year changes in withdrawals can be substantial, and the relation between potentiometric surfaces in the major aquifers and year-to-year withdrawals is not well established. The estimated long-term (19-year) groundwater-level changes for the Prairie du Chien-Jordan and Mount Simon-Hinckley aquifers have not been large based on data and maps produced during this study, despite the large seasonal fluctuations shown by the March and August 2008 synoptic measurements.

Effects of UV radiation on phytoplankton

Smith, Raymond C.; Cullen, John J.

1995-07-01

It is now widely documented that reduced ozone will result in increased levels of ultraviolet (UV) radiation, especially UV-B (280-320nm), incident at the surface of the earth [Watson, 1988; Anderson et al., 1991; Schoeberl and Hartmann, 1991; Frederick and Alberts, 1991; WMO, 1991; Madronich, 1993; Kerr and McElroy, 1993], and there is considerable and increasing evidence that these higher levels of UV-B radiation may be detrimental to various forms of marine life in the upper layers of the ocean. With respect to aquatic ecosystems, we also know that this biologically- damaging mid-ultraviolet radiation can penetrate to ecologically- significant depths in marine and freshwater systems [Jerlov, 1950; Lenoble, 1956; Smith and Baker, 1979; Smith and Baker, 1980; Smith and Baker, 1981; Kirk et al., 1994]. This knowledge, plus the dramatic decline in stratospheric ozone over the Antarctic continent each spring, now known to be caused by anthropogenically released chemicals [Solomon, 1990; Booth et al., 1994], has resulted in increased UV-environmental research and a number of summary reports. The United Nations Environmental Program (UNEP) has provided recent updates with respect to the effects of ozone depletion on aquatic ecosystems (Hader, Worrest, Kumar in UNEP 1989, 1991, Hader, Worrest, Kumar and Smith UNEP 1994) and the Scientific Committee on Problems of the Environment (SCOPE) has provided [SCOPE, 1992] a summary of the effects of increased UV radiation on biological systems. SCOPE has also reported [SCOPE, 1993] on the effects of increased UV on the biosphere. In addition, several books have recently been published reviewing various aspects of environmental UV photobiology [Young et al., 1993], UV effects on humans, animals and plants [Tevini, 1993], the biological effects of UV radiation in Antarctica [Weiler and Penhale, 1994], and UV research in freshwater ecosystems [Williamson and Zagarese, 1994]. Several other reviews are relevant [NAS, 1984; Caldwell et al., 1986; Worrest, 1986; NOAA, 1987; Smith, 1989; Smith and Baker, 1989; Voytek, 1990; Häder, 1993; Acevedo and Nolan, 1993; Holm-Hansen et al., 1993; Vincent and Roy, 1993; Biggs and Joyner, 1994; Williamson and Zagarese, 1994; Karentz, 1994; Cullen and Neale, 1993; Cullen and Neale, 1994]. As Hader et al. have summarized [UNEP, 1989; UNEP, 1991], "UV-B radiation in aquatic systems: 1) affects adaptive strategies (e.g., motility, orientation); 2) impairs important physiological functions (e.g., photosynthesis and enzymatic reactions); and 3) threatens marine organisms during their developmental stages (e.g., the young of finfish, shrimp larvae, crab larvae)". Possible consequences to aquatic systems include: reduced biomass production; changes in species composition and biodiversity; and alterations of aquatic ecosystems and biogeochemical cycles associated with the above changes. Within the past four years, our knowledge with respect to the environmental effects of ozone-related increased levels of UV-B has increased significantly, and numerous efforts have been directed toward process-oriented studies of UV responses in plants and animals. Consensus is building toward the view that current levels of UV play a major role as an ecological determinant, influencing both survival and distribution, and are thus deserving of increased study independent of ozone-related UV-B increases. This review outlines U.S. research subsequent to 1991 and emphasizes studies concerned with phytoplankton.
