CIBA-GEIGY/Drakenfeld Colors is dedicated to the research and development of consistent and cost-effective ceramic stains for the whitewares industry. After identifying the trends in color for the 1990s. CIBA-GEIGY/Drakenfeld Colors initiated an extensive R D project to improve zircon ion corals for the whitewares industry. These color trends indicated a need for stronger and cleaner zircon iron corals. This paper discusses the chemistry and crystal structure of zircon iron corals. A historical review of Drakenfeld corals will also be presented. The most recent development in Drakenfeld corals will then be compared to other commercially available zircon iron corals. Taking intomore » consideration these comparisons, conclusions will be drawn suggesting the coral of choice for the 1990s.« less

Ultraviolet, visible, and gravity astrophysics: A plan for the 1990's

NASA Technical Reports Server (NTRS)

1990-01-01

NASA's Office of Space Science and Applications (OSSA) receives advice on scientific strategy and priorities from the U.S. National Academy of Sciences. Guidance to the OSSA Astrophysics Division, in particular, is provided by dedicated academy committees, ad hoc study groups, and, at ten-year intervals, by broadly mandated astronomy and astrophysics survey committees charged with making recommendations for the coming decade. Many of the academy's recommendations have important implications for the conduct of ultraviolet and visible-light astronomy from space. Moreover, these areas are now poised for an era of rapid growth. Through technological progress, ultraviolet astronomy has already risen from a novel observational technique four decades ago to the mainstream of astronomical research today. Recent developments in space technology and instrumentation have the potential to generate comparably dramatic strides in observational astronomy within the next ten years. In 1989, the Ultraviolet and Visible Astrophysics Branch of the OSSA Astrophysics Division recognized the need for a new, long-range plan that would implement the academy's recommendations in a way that yielded the most advantageous use of new technology. NASA's Ultraviolet, Visible, and Gravity Astrophysics Management Operations Working Group was asked to develop such a plan for the 1990's. Since the branch holds programmatic responsibility for space research in gravitational physics and relativity, as well as for ultraviolet and visible-light astrophysics, missions in those areas were also included. The working group met throughout 1989 and 1990 to survey current astrophysical problems, assess the potential of new technologies, examine prior academy recommendations, and develop the implementation plan. The present report is the product of those deliberations. Key astrophysical questions to be addressed cover topics such as the structure and evolution of the early universe, energetics of active

Expectations and beliefs in science communication: Learning from three European gene therapy discussions of the early 1990s.

PubMed

Meyer, Gitte

2016-04-01

There is widespread agreement that the potential of gene therapy was oversold in the early 1990s. This study, however, comparing written material from the British, Danish and German gene therapy discourses of the period finds significant differences: Over-optimism was not equally strong everywhere; gene therapy was not universally hyped. Against that background, attention is directed towards another area of variation in the material: different basic assumptions about science and scientists. Exploring such culturally rooted assumptions and beliefs and their possible significance to science communication practices, it is argued that deep beliefs may constitute drivers of hype that are particularly difficult to deal with. To participants in science communication, the discouragement of hype, viewed as a practical-ethical challenge, can be seen as a learning exercise that includes critical attention to internalised beliefs. © The Author(s) 2014.

Effects of increased urbanization from 1970's to 1990's on storm-runoff characteristics in Perris Valley, California

USGS Publications Warehouse

Guay, J.R.

1996-01-01

Urban areas in Perris Valley, California, have more than tripled during the last 20 years. To quantify the effects of increased urbanization on storm runoff volumes and peak discharges, rainfall-runoff models of the basin were developed to simulate runoff for 1970-75 and 1990-93 conditions. Hourly rainfall data for 1949-93 were used with the rainfall-runoff models to simulate a long-term record of storm runoff. The hydrologic effects of increased urbanization from 1970-75 to 1990-93 were analyzed by comparing the simulated annual peak discharges and volumes, and storm runoff peaks, frequency of annual peak discharges and runoff volumes, and duration of storm peak discharges for each study period. A Log-Pearson Type-III frequency analysis was calculated using the simulated annual peaks to estimate the 2-, 5-, 10-, 25-, 50-, and 100-year recurrence intervals. The estimated 2-year discharge at the outlet of the basin was 646 cubic feet per second for the 1970-75 conditions and 1,328 cubic feet per second for the 1990-93 conditions. The 100-year discharge at the outlet of the basin was about 14,000 cubic feet per second for the 1970-75 and 1990-93 conditions. The station duration analysis used 925 model-simulated storm peaks from each basin to estimate the percent chance a peak discharge is exceeded. At the outlet of the basin, the chances of exceeding 100 cubic feet per second were about 33 percent under 1970-75 conditions and about 59 percent under 1990-93 conditions. The chance of exceeding 2,500 cubic feet per second at the outlet of the basin was less than 1 percent higher under the 1990-93 conditions than under the 1970-75 conditions. The increase in urbanization from the early 1970's to the early 1990's more than doubled the peak discharges with a 2-year return period. However, peak discharges with return periods greater than 50 years were not significantly affected by the change in urbanization.

AIDS and the status of women. Challenges and perspectives for the 1990s.

PubMed

1990-10-01

WHO and the Swedish Government hosted the expert group meeting on women and HIV/AIDS in Vienna, August in 1990. Attendees concentrated their discussions on government recognized entities (national machinery) responsible for women's advancement and how they can assist in forming national policies to better women's status and limit the effect of HIV/AIDS. A very important issue came out of this meeting that had not yet been addressed in AIDS prevention strategies--the fundamental problem of women's subordination as a component of the HIV/AIDS epidemic. In addition, even though national groups for women's advancement have worked hard to rectify subordination, they have not yet addressed AIDS as a barrier to equality. Subordination of women varies from country to country, nevertheless they are all vulnerable to HIV/AIDS worldwide. They do not have equal access to education, information, and health services. They cannot demand that sexual partners practice safe sex. Despite being ill, they are expected to continue caring for their families. The national machinery must be able to assemble needed resources and assure implementation of these policies. It should encourage government policies to improve maternal and child health and family planning services, to control sexually transmitted diseases, and to provide adequate counseling and research. National AIDS committees and national machinery should communicate and form linkages to advance the status of women. Preventing the spread of HIV/AIDS cannot occur, however, if men and women do not cooperate. WHO estimated that at least 500,000 women and children acquired AIDS in the 1980s. It expects an additional 3 million in the 1990s. In the early 1990s, 8-10 million people are infected with HIV.

An interdecadal regime shift in rainfall predictability related to the Ningaloo Nino in the late 1990s

NASA Astrophysics Data System (ADS)

Doi, T.; Behera, S. K.; Yamagata, T.

2016-02-01

The global warming and the Interdecadal Pacific Oscillation (IPO) started influencing the coastal ocean off Western Australia, leading to a dramatic change in the regional climate predictability. The warmer ocean started driving rainfall variability regionally there after the late 1990s. Because of this, rainfall predictability near the coastal region of Western Australia on a seasonal time scale was drastically enhanced in the late 1990s; it is significantly predictable 5 months ahead after the late 1990s. The high prediction skill of the rainfall in recent decades is very encouraging and would help to develop an early warning system of Ningaloo Nino/Nina events to mitigate possible societal as well as agricultural impacts in the granary of Western Australia.

Research on health inequalities can be instrumental in drawing attention to the health of socioeconomically vulnerable groups in India in the context of rapid economic growth. It can shape the dialogue for public health action, emphasizing the need for greater investments in health, and monitor effectiveness of health programs. Our objective was to examine trends in studies on health inequalities in the last 25 years. We conducted a systematic literature review of studies on health inequalities published from 1990. The year, 1990, marked the beginning of economic reforms and liberalization in India. We searched PubMED using key terms to identify 8800 articles between 1990 and 2016; we identified 1,312 final studies for review. Key domains of analysis included measures of equity, health outcomes, populations studied, year of publication, study methodology, study focus (descriptive versus analytical), and location of main author. We found an increase in studies on health inequalities after 2005. About 88 % of the studies utilized quantitative methods for analysis. About 8 % of the studies related to health interventions or programs; the number of intervention studies have been increasing since 2010. A majority of studies were led by authors based in India. Early studies focused on mortality, communicable and non-communicable diseases, and nutrition, while later studies have focused on non-communicable diseases, mental health, risk factors, and injuries. Studies on women and children comprised nearly half of the literature; studies on the youth (15-24 years or as defined by the study) and elderly have been rising. Wealth and income were the most common measures of equity, followed by education and gender. The proportion of studies on wealth, education, region and caste have stayed consistent over time, while studies on gender disparities have been rising. In a country as diverse as India with large social inequalities combined with rapid economic growth, research

2014-01-01

We document the historical and cultural shifts in how gay and bisexual men have used the Internet for sexuality between the 1990s and 2013-including shifting technology as well as research methods to study gay and bisexual men online. Gay and bisexual men have rapidly taken to using the Internet for sexual purposes: for health information seeking, finding sex partners, dating, cybersex, and pornography. Men have adapted to the ever-evolving technological advances that have been made in connecting users to the Internet-from logging on via dial-up modem on a desktop computer to geo-social-sexual networking via handheld devices. In kind, researchers have adapted to the Internet to study gay and bisexual men. Studies have carefully considered the ethics, feasibility, and acceptability of using the Internet to conduct research and interventions. Much of this work has been grounded in models of disease prevention, largely as a result of the ongoing HIV/AIDS epidemic. The need to reduce HIV in this population has been a driving force to develop innovative research and Internet-based intervention methodologies. The Internet, and specifically mobile technology, is an environment gay and bisexual men are using for sexual purposes. These innovative technologies represent powerful resources for researchers to study and provide outreach.

Accelerated deforestation in the humid tropics from the 1990s to the 2000s

Kim, Do-Hyung; Sexton, Joseph O.; Townshend, John R.

2015-05-01

Using a consistent, 20 year series of high- (30 m) resolution, satellite-based maps of forest cover, we estimate forest area and its changes from 1990 to 2010 in 34 tropical countries that account for the majority of the global area of humid tropical forests. Our estimates indicate a 62% acceleration in net deforestation in the humid tropics from the 1990s to the 2000s, contradicting a 25% reduction reported by the United Nations Food and Agriculture Organization Forest Resource Assessment. Net loss of forest cover peaked from 2000 to 2005. Gross gains accelerated slowly and uniformly between 1990-2000, 2000-2005, and 2005-2010. However, the gains were overwhelmed by gross losses, which peaked from 2000 to 2005 and decelerated afterward. The acceleration of humid tropical deforestation we report contradicts the assertion that losses decelerated from the 1990s to the 2000s.

Technical Report: The Development and Experience with UAV Research Applications in Former Czechoslovakia (1960s-1990s)

Kolejka, Jaromír; Plánka, Ladislav

2018-02-01

The use of unmanned aerial vehicles in a number of fields of human activity represents the second wave of interest in the development and application of automated flying remotely controlled machines to collect aerial data. The former Czechoslovakia was one of the world's leading countries in the 1960s-1990s in terms of an unprecedented boom of development and applications of flying machines for imaging the Earth's surface. The reasons for their use were the same as today. Since the mid-1960s, radio-controlled (RC) models of aircraft carrying various types of photographic cameras have been developed. In spite of many administrative constraints, kite helicopters, fixed-wing aircrafts, and rogallo-wing aircrafts gradually began to be used in research. The photographic cameras for 1, 2, 4, and 6 bands carried by RC-aircraft models were developed in cooperation with leading Czech companies. These cameras used colour and black-and-white films, positive and negative films, and panchromatic, spectrozonal, and multispectral films. The general methodology and the RC-aircraft model application rules were both developed. The dominant processing method was the visual image interpretation, with and without the assistance of instruments. Optical and digital image mixers were used in Czechoslovakia, so it was possible to use natural and unnatural colour composites to highlight the studied phenomenon. A number of examples of the techniques and the scientific applications are presented in the article.

Oinas-Kukkonen, Henry; Kerola, Pentti; Oinas-Kukkonen, Harri; Similä, Jouni; Pulli, Petri

This paper discusses the internationalization of software business in the Oulu region. Despite its small size, the region grew rapidly and very successfully into a global information and communication technology business center. The University of Oulu, which was the northern most university in the world at the time of its establishment (1958) had a strong emphasis on engineering since its very beginning. Research on electronics was carried out since the early 1960s. Later, when the Department of Information Processing Science was founded in 1969, research on information systems and later also on software engineering was carried out. This paper discusses the role of the information systems and software engineering research for the business growth of the region. Special emphasis is put on understanding the role of system-theoretical and software development expertise for transferring research knowledge into practice.

Enhanced Biennial Variability in the Pacific due to Atlantic Capacitor Effect after the Early 1990s

NASA Astrophysics Data System (ADS)

WANG, L.; Yu, J. Y.; Paek, H.

2016-12-01

The El Niño-Southern Oscillation (ENSO) and Pacific subtropical highs (PSHs) have major impacts on social and ecological systems through their influences on severe natural hazards including tropical storms, coastal erosions, droughts and floods. The ability to forecast ENSO and PSHs requires an understanding of the underlying physical mechanisms that drive their variability. Here we present an Atlantic capacitor effect mechanism to suggest the Atlantic as a key pacemaker of the biennial variability in the Pacific including ENSO and PSHs in recent decades, while the pacemaker was previously considered to be mainly lied within the Pacific or Indian Oceans. The "charging" (i.e., ENSO imprinting the North Tropical Atlantic (NTA) sea surface temperature (SST) via an atmospheric bridge mechanism) and "discharging" (i.e., the NTA SST triggering the following ENSO via a subtropical teleconnection mechanism) process works alternately, generating the biennial rhythmic changes in the Pacific. After the early-1990s, the positive phase of the Atlantic Multidecadal Oscillation and global warming provides more favorable background states over the NTA that enable the Atlantic capacitor effect to operate more efficiently, giving rise to enhanced biennial variability in the Pacific which may increase the occurrence frequency of severe natural hazard events. The results highlight the increasing important role of the Atlantic-Pacific coupling as an important pacemaker of the ENSO cycle in recent decades.

To assess author credentials of quantitative research in nursing, the composition of the research teams, and the disciplinary focus of the theories tested. Nursing Research, Western Journal of Nursing Research, and Journal of Advanced Nursing were selected for this descriptive study; 1990, 1995, 2000, 2005, and 2010 were included. The final sample consisted of 484 quantitative research articles. From 1990 to 2010, there was an increase in first authors holding doctoral degrees, research from other countries, and funding. Solo authorship decreased; multi-authorship and multidisciplinary teams increased. Theories tested were mostly from psychology; the testing of nursing theory was modest. Multidisciplinary research far outdistanced interdisciplinary research. Quantitative nursing research can be characterized as multidisciplinary (distinct theories from different disciplines) rather than discipline-specific to nursing. Interdisciplinary (theories synthesized from different disciplines) research has been conducted minimally. This study provides information about the growth of the scientific knowledge base of nursing, which has implications for practice. © 2013 Sigma Theta Tau International.

The role of NASA-Langley is to perform basic and applied research necessary for the advancement of aeronautics and spaceflight, to generate new and advanced concepts for the accomplishment of related national goals, and to provide research advice, technological support, and assistance to other NASA installations, other government agencies, and industry. Some of the significant tests are highlighted which were performed during 1990 in the NASA-Langley test facilities, a number of which are unique in the world. Both the broad range of the research and technology activities at NASA-Langley and the contributions of this work toward maintaining U.S. leadership in aeronautics and space research are illustrated. Other highlights of Langley research and technology for 1990 are described in Research and Technology 1990 Langley Research Center.

U.S. and U.S.S.R agree on ocean research

NASA Astrophysics Data System (ADS)

Ostenso, Ned A.

On June 1, 1990, George Bush and Mikhail S. Gorbachev signed a renegotiated bilateral agreement for cooperation in oceanographic research. The original agreement for “Studies of the World Ocean,” signed in 1972, did not provide for the protection of intellectual property. The new agreement is administered by executive secretaries from both countries working under the U.S.-U.S.S.R. Joint Committee on Cooperation in Ocean Studies. The committee held its first meeting in Moscow September 14-17, 1990, at the headquarters of the U.S.S.R. State Committee for Science and Technology (GKNT).The U.S. delegation was led by John A. Knauss, undersecretary of commerce for oceans and atmosphere and administrator of the National Oceanic and Atmospheric Administration (NOAA), and included Ned A. Ostenso, executive secretary of the agreement; Thomas E. Murray, NOAA; M. Grant Gross, National Science Foundation; Robert S. Winokur, U.S. Navy; Bonnie McGregor Stubblefield, U.S. Geological Survey; William S. Busch, Office of Science and Technology Policy; and William A.

East Asian (EA) summer monsoon shows considerable differences in the mean state and principal modes of interannual variation between early summer (May-June, MJ) and late summer (July-August, JA). The present study focuses on the early summer (MJ) precipitation variability. We find that the interannual variation of the MJ precipitation and the processes controlling the variation have been changed abruptly around the mid-1990s. The rainfall anomaly represented by the leading empirical orthogonal function has changed from a dipole-like pattern in pre-95 epoch (1979-1994) to a tripole-like pattern in post-95 epoch (1995-2010); the prevailing period of the corresponding principal component has also changed from 3-5 to 2-3 years. These changes are concurrent with the changes of the corresponding El Nino-Southern Oscillation (ENSO) evolutions. During the pre-95 epoch, the MJ EA rainfall anomaly is coupled to a slow decay of canonical ENSO events signified by an eastern Pacific warming, which induces a dipole rainfall feature over EA. On the other hand, during the post-95 epoch the anomalous MJ EA rainfall is significantly linked to a rapid decay of a central Pacific warming and a distinct tripolar sea surface temperature (SST) in North Atlantic. The central Pacific warming-induced Philippine Sea anticyclone induces an increased rainfall in southern China and decreased rainfall in central eastern China. The North Atlantic Oscillation-related tripolar North Atlantic SST anomaly induces a wave train that is responsible for the increase northern EA rainfall. Those two impacts form the tripole-like rainfall pattern over EA. Understanding such changes is important for improving seasonal to decadal predictions and long-term climate change in EA.

The East Asian summer monsoon is affected by processes in the mid-high latitudes in addition to various tropical and subtropical systems. The present study investigates the summer sea level pressure (SLP) variability over northern East Asia (NEA) and emphasizes the closed active center over the Mongolian region. It is found that the seasonal mean Mongolian SLP (MSLP) anomaly is closely connected with the variability of summertime regional synoptic extra-tropical cyclones on longer time scales. A significant inter-decadal increase in the MSLP around the early 1990s has been detected, which is accompanied by a weakening in the activity of regional extra-tropical cyclones. Recent warming over NEA may have a contribution to the inter-decadal change, which features evidently meridional inhomogeneity around 45°N. The inhomogeneous air temperature anomaly distribution results in decreased vertical wind shear, reduced atmospheric baroclinicity over the Mongolian region, and thus inactive regional cyclones and increased MSLP in the latter decade. The associated temperature anomaly distribution may be partly attributed to regional inhomogeneity in cloud and radiation anomalies, and it is further maintained by two positive feedback mechanisms associated with atmospheric internal processes: one via adiabatic heating and the other via horizontal temperature advection.

The growth of psychopharmacology in the 1990s: evidence-based practice or irrational exuberance.

PubMed

Rosenheck, Robert

2005-01-01

The rapid growth in sales of psychotropic medications during the late 1980s and 1990s, eventually reaching $20 billion/year, reflected the increased use of seritonin reuptake inhibitors for depression and atypical antipsychotics for schizophrenia. Recently, however, some of the therapeutic claims for these medications have been challenged, and under-appreciated risks have turned out to be significant liabilities. Drug manufacturers increasingly dominate clinical trials research and evidence suggests that study designs and data presentations have been slanted to show products in a favorable light while unfavorable data were suppressed. At the same time, during the 1990s, potentially independent voices did not effectively or consistently present countervailing views. The extensive financial ties between the pharmaceutical industry and academic researchers, professional associations, and consumer groups may also have discouraged expression of critical views. Additionally, the narrow legal mandate of the FDA to evaluate the safety and efficacy of new drugs only in comparison to placebo (rather than in comparison to other treatments) probably limited its contribution. In the absence of reliable, impartial research on the risk and benefits of psychotropic medications, both before and after they are brought to market, pharmacy benefits management cannot achieve its goal of maximizing health care benefits per dollar spent. Further institutional support is needed for independent research, either conducted or funded by the federal government.

Causes of the Decline in Cigarette Smoking Among African American Youths From the 1970s to the 1990s

PubMed Central

Foulds, Jonathan

2011-01-01

Adult cigarette smoking prevalence trends among African Americans (AAs) and Whites are similar. However, during the decline in youth smoking that occurred between the mid-1970s and the early 1990s, the drop in smoking rates among AA adolescents was more than double that among Whites. We examined the evidence for potential explanations for this phenomenon. On the basis of our findings, we propose that racial differences in parental attitudes, religious ties, negative perceptions and experiences of the health effects of smoking, worsening poverty, increased use of food stamps, and price sensitivity were major factors contributing to the more rapid decrease in and continued lower rates of smoking among AA youths.

2014-01-01

In this review, we document the historical and cultural shifts in how gay and bisexual men have used the Internet for sexuality between the 1990s and 2013. Over that time, gay and bisexual men have rapidly taken to using the Internet for sexual purposes: sexual health information seeking, finding sex partners, dating, cybersex, and pornography. Gay and bisexual men have adapted to the ever-evolving technological advances that have been made in connecting users to the Internet—from logging into the World Wide Web via dial-up modem on a desktop computer to geo-social and sexual networking via a handheld device. In kind, researchers too have adapted to the Internet to study gay and bisexual men, though not at the same rapid pace at which technology (and its users) have advanced. Studies have carefully considered the ethics, feasibility, and acceptability of using the Internet to conduct research and interventions with gay and bisexual men. Much of this work has been grounded in models of disease prevention, largely as a result of the ongoing HIV/AIDS epidemic. The urgent need to reduce HIV in this population has been a driving force to develop innovative research and Internet-based intervention methodologies. Moving forward, a more holistic understanding of gay and bisexual men's sexual behavior might be warranted to address continued HIV and STI disparities. The Internet, and specifically mobile technology, is an environment gay and bisexual men are using for sexual purposes. These innovative technologies represent powerful resources for researchers to study and provide rapidly evolving outreach to gay and bisexual men. PMID:24754360

Geologic studies in Alaska by the U.S. Geological Survey, 1990

USGS Publications Warehouse

Bradley, Dwight C.; Ford, Arthur B.

1992-01-01

This collection of papers continues the annual series of U.S. Geological Survey (USGS) reports on geologic investigations in Alaska. From 1975 through 1988, the series was published as USGS circulars. The first of these appeared under the title "The United States Geological Survey in Alaska: Accomplishments during 1975," and the series continued to the last annual circular entitled "Geologic studies in Alaska by the U.S. Geological Survey during 1987," which reflects a title change made in 1986. This 1990 volume continues the bulletin format started in 1988. As in 1989, this volume separates shorter contributions as Geologic Notes from more extensive Articles.This 1990 volume of 18 Articles and 4 Geologic Notes represents the broad range of USGS research activities carried out in Alaska over the past few years. These studies include topics on mineral and other resources such as gold (Y eend), platinum-group elements (Cathrall and Antweiler), coal (Roberts, Stricker, and Affolter), and petroleum (Howell, Bird, and others). Many other investigations provide background geochemical (Kilburn, Box, and others) and geologic data needed for resource evaluation as well as for determining the general geologic framework of Alaska, as in stratigraphic, sedimentologic, and paleontologic and radiometric age studies (Blodgett, Clough, and others; Box and Elder; Dickinson and Skipp; Marincovich and Moriya; McLean and Stanley; Stanley, Flores, and Wiley; Roeske, Pavlis, and others); geophysics (Sampson, Labson, and Long); structure and tectonic evaluations (Bradley and Kosky; Clendenen, Sliter, and Byrne; Karl; Csejtey; Howell, Johnsson, and others); and geomorphic and late Quaternary studies (Carter and Hillhouse; Galloway, Huebner, and others; McGimsey, Richter, and others; Nelson and Carter). These studies span nearly the entire State from the North Slope and Brooks Range to interior, southwestern, and south-central Alaska (fig. 1).Two bibliographies (White) at the end of the

To compare the impact of low-grade haemorrhage on neurocognitive function in 16-year-old adolescents born preterm, by grade of intraventricular haemorrhage, and term controls. We evaluated 338 preterm adolescents (birth weight 600-1250 g) for intelligence, executive function and memory tasks. Eleven had grade 3-4 haemorrhage, 44 had grade 2, 31 had grade 1, and 251 had no haemorrhage. Group comparisons were made with 102 term age-matched controls, and regression models used to identify the risk that low-grade haemorrhage posed for cognitive, executive function and memory deficits. Preterm adolescents with grade 2 haemorrhage had higher deficit rates of verbal intelligence, receptive vocabulary, phonemic fluency, cognitive flexibility and phonological fluency than preterm adolescents with grade 1 or no haemorrhage, compared with term controls. After excluding preterm adolescents with both grade 2 haemorrhage and cystic periventricular leukomalacia, those with isolated grade 2 haemorrhage remained at greater risk of cognitive and executive function deficits than term controls and of cognitive deficits than preterm adolescents with no haemorrhage. Our findings suggest that preterm adolescents born in the early 1990s with isolated grade 2 haemorrhage are at increased risk of learning challenges, including cognitive and executive function deficits. ©2014 Foundation Acta Paediatrica.

El Nino during the 1990s: Harbinger of Climatic Change or Normal Fluctuation?

NASA Technical Reports Server (NTRS)

Wilson, Robert M.

1999-01-01

Today, El Nino refers to the extreme warming episodes of the globally effective, coupled ocean-atmospheric interaction commonly known as ENSO (i.e., "El Nino-Southern Oscillation"). Concerning its observed decadal frequency and severity, El Nino during the 1990s has often been regarded as being anomalous. Results of analysis reported herein, however, appear to mitigate this belief. For example, regarding the frequency and severity of El Nino, the decade of the 1990s is found to compare quite favorably with that of preceding decades. Hence, the 1990s probably should not be regarded as being anomalous. On the other hand, the number of El Nino-related months per decade has sharply increased during the 1990s, as compared to the preceding four decades, hinting of a marginally significant upward trend. Perhaps, this is an indication that the Earth is now experiencing an ongoing global climatic change. Continued vigilance during the new millennium, therefore, is of paramount importance for determining whether or not this "hint" of a global change is real or if it merely reflects a normal fluctuation of climate.

Spectroscopic and photometric observations of SN 1990N were obtained at ultraviolet and optical wavelengths, beginning 14 days before maximum light. The early observations reveal important differences from spectra of SN Ia's around maximum light. Photometry and spectroscopy obtained after maximum show that SN 1990N is a typical SN Ia and that most of the observed differences are due to the early epoch of the observations. The most significant characteristics are (1) the high velocities of Ca and Si up to 22,000 km/s; (2) the presence of Co and Fe 2 weeks before maximum; and (3) the more rapid increase in the UV flux compared to the optical. The most popular models for white dwarf deflagration that have provided the standard interpretation for SN Ia's at maximum light do not reproduce the high velocities of Ca II and Si II lines observed in SN 1990N.

At the start of FY 1990, the atmospheric sciences and carbon dioxide research programs within the Office of Health and Environmental Research (OHER) were gathered into the new Atmospheric and Climate Research Division (ACRD). One of the central missions of this new division is to provide the Department of Energy with scientifically defensible information on the local, regional, and global distributions of energy-related pollutants and their effects on climate. This information is vital to the definition and implementation of a sound national energy strategy. Because much of the work done at PNL during FY 1990 falls under the umbrella ofmore » the new ACRD, we are including in this volume the progress and status reports for all OHER atmospheric and climate research projects at PNL. The description of ongoing atmospheric and climate research at PNL is organized along two broad research areas; atmospheric research and climate research.

An unexpected rise in strontium-90 in US deciduous teeth in the 1990s.

PubMed

Mangano, Joseph J; Gould, Jay M; Sternglass, Ernest J; Sherman, Janette D; McDonnell, William

2003-12-30

For several decades, the United States has been without an ongoing program measuring levels of fission products in the body. Strontium-90 (Sr-90) concentrations in 2089 deciduous (baby) teeth, mostly from persons living near nuclear power reactors, reveal that average levels rose 48.5% for persons born in the late 1990s compared to those born in the late 1980s. This trend represents the first sustained increase since the early 1960s, before atmospheric weapons tests were banned. The trend was consistent for each of the five states for which at least 130 teeth are available. The highest averages were found in southeastern Pennsylvania, and the lowest in California (San Francisco and Sacramento), neither of which is near an operating nuclear reactor. In each state studied, the average Sr-90 concentration is highest in counties situated closest to nuclear reactors. It is likely that, 40 years after large-scale atmospheric atomic bomb tests ended, much of the current in-body radioactivity represents nuclear reactor emissions.

Marriage, divorce, and remarriage in the 1990's.

PubMed

Norton, A J; Miller, L F

1992-10-01

Recent trends in marriage, divorce and redivorce, and remarriage were gleaned from cohort data from the US Supplement to the Current Population Survey, 1990, on the frequency of women entering and exiting a verity of marital statuses. Marriage patterns are described also in terms of their interrelationship with educational attainment, fertility history, age, race and Hispanic origin, age at marital event, and duration in marital status. the effects of marriage patterns on children are also considered. Future trends are anticipated along with their impact on families. The trend has been toward a significant number of adults and children living in one-parent families. This situation is also usually one of poverty and social deprivation. The time spent by children in one-parent families is estimated at almost 50%. There are 14 detailed tables to supplement the text. The appended tables and discussion provide background information on the accuracy of estimates. The increasing trend of divorce has meant that between the 1960s and 1980 the divorce rate doubled and reached the point where 1 out of 2 marriages was expected to end in divorce. During the 1980s, the rate remained the same, and first marriage and remarriage declined. Declines may be due to delay in marriage or to more people never marrying. Between 1975 and 1990, the percent of women ever married declined for all age groups; for women 20-24 years old the decline was from 63 to 38%. Marriage patterns were different for Blacks and Whites, but both experienced declines in first marriage. Black women will marry later than White women and will include a greater proportion who will never marry. Hispanic patterns were similar those of Whites. The slight drop in the percent divorcing after a first marriage between 1985 and 1990 showed less divorce for the younger age groups and more for the older age groups. 4 of 10 marriages involve a second or higher order marriage for 1 or both partners. The percent remarrying

Since the early 1990s with the arrival of a variety of new technologies, the capacity for authentic astronomical research at the high school level has skyrocketed. This potential, however, has not realised the bright-eyed hopes and dreams of the early pioneers who expected to revolutionise science education through the use of telescopes and other astronomical instrumentation in the classroom. In this paper, a general history and analysis of these attempts is presented. We define what we classify as an Astronomy Research in the Classroom (ARiC) project and note the major dimensions on which these projects differ before describing the 22 major student research projects active since the early 1990s. This is followed by a discussion of the major issues identified that affected the success of these projects and provide suggestions for similar attempts in the future.

The goal of this paper is to examine recent trends in educational stratification for Latin American adolescents growing up in three distinct periods: the 1980s, during severe recession; the 1990s, a period of structural adjustments imposed by international organizations; and the late 2000s, when most countries in the region experienced positive and stable growth. In addition to school enrollment and educational transitions, we examine the quality of education through enrollment in private schools, an important aspect of inequality in education that most studies have neglected. We use nationally representative household survey data for the 1980s, 1990s and 2000s in Brazil, Chile, Mexico and Uruguay. Our overall findings confirm the importance of macroeconomic conditions for inequalities in educational opportunity, suggesting important benefits brought up by the favorable conditions of the 2000s. However, our findings also call attention to increasing disadvantages associated with the quality of the education adolescents receive, suggesting the significance of the EMI framework-Effectively Maintained Inequality-and highlighting the value of examining the quality in addition to the quantity of education in order to fully understand educational stratification in the Latin American context.

Educating and training industrial ecologists for the 1990s.

PubMed

Troxell, D E

1992-02-01

For industrial ecology to become a reality and flourish, many talents must be integrated into a single system. Basically, there are four types of technologists who must be brought together to create a system: (i) technical specialists-those that can take the state of knowledge to the state of the art and eventually to the state of practice; (ii) technical "generalists"-those that can integrate diverse technologies into a comprehensive solution; (iii) technical managers-those that can lead technical efforts to an optimal solution (these people must have management skills in their area); and (iv) program managers-those that can understand and merge the overall efforts of technology, business, schedule, and finance. The initial questions for industrial ecology in the 1990s are: Do these people presently exist in industry? What will be needed to bring new people (recent graduates) into the field of industrial ecology? For this decade, the people who will develop and lead the concept of industrial ecology are presently in industry. However, certainly few, if any, today understand the concept of industrial ecology as a system issue. Training will be needed for these practitioners of the 1990s so that the overall goal and the mechanism for achieving industrial ecology are understood. A three-tiered approach is presented to define the education/training needed, to conduct training on an industry basis, and then to initiate the training to be done within a corporation. The three tiers propose the use of universities, professional societies, and industry groups. Having universities participate in the training of the 1990s industrial ecologists will give universities insight to the development of industrial ecology, and access to industry needs so that curriculum can be initiated to educate the industrial ecologists of the future.

No longer only a mainframe domain, the data processing enterprise also includes the midrange and workstation platforms, either local or remote. This expanded view of the enterprise has encouraged more and more businesses to take a strategic, long-range view of information management rather than the short-term tactical approaches of the past. This paper will highlight some of the significant aspects of data storage in the enterprise for the 1990's.

Changing attitudes toward aging policy in the United States during the 1980s and 1990s: a cohort analysis.

PubMed

Silverstein, M; Angelelli, J J; Parrott, T M

2001-01-01

This research assessed how the attitudes of Americans toward government programs that serve older people changed between the mid-1980s and late 1990s and how much of the shift was dueto intracohort change and how much was due to cohort replacement. Data come from three nationally representative cross-sectional samples, surveyed by telephone in 1986 (N = 1.209), 1990 (N = 1,500), and 1997 (N = 1,559). Attitudes of Americans have become less supportive of expanding entitlement programs for older people and more supportive of cutting their costs and benefits. Between 1986 and 1997, most cohorts, particularly older adults, grew more in favor of maintaining Social Security benefit levels but less in favor of expanding them. Young adults tended to be driving the societal shift in attitudes toward decreasing benefits. Intercohort change was more important than cohort replacement in this process. Analyses of change in 2 attitude domains between 1990 and 1997 revealed that the general population felt less strongly that older people are entitled to benefits and expressed greater opposition to the associated costs. However, young adults moderated their concerns about costs as they got older, although the young adults in the cohort replacing them had become more critical of the principle of entitlement. These findings enhance the understanding of the roles that historical conditions and aging play in shaping the attitudes of adult cohorts toward public programs for older citizens. Discrepant findings based on the intercohort change in younger age groups are reconciled by differentiating maturation effects from period effects on impressionable youth.

Adequacy of dietary intakes and poverty in India: trends in the 1990s.

PubMed

Mahal, Ajay; Karan, Anup K

2008-03-01

Linear programming methods, indicators of nutritional adequacy from the Indian Council of Medical Research and household expenditure survey data from the National Sample Survey Organization were used to construct poverty lines for India. Poverty ratios were calculated for 1993--1994 and 1999--2000 on the basis of nutritional adequacy poverty lines and compared to official estimates of poverty based on energy requirements. Nutritional adequacy poverty lines are higher than official poverty lines, particularly in rural areas. The application of nutritional adequacy poverty lines points to greater rural-urban poverty differences than in official estimates. Declines in rural poverty during the 1990s were also slower under the nutritional adequacy definition, especially in south India. There is a greater degree of rural-urban and regional bias in nutritional adequacy poverty reduction than suggested by official data. Inter-state variations in changes in nutritional poverty and official poverty in the 1990s are largely explained by differences in assumptions on overall price movements. However, relative price movements in food items also played a role, particularly the slow increase in prices of cereals and edible oils in comparison to the prices of pulses, and in some southern states, compared to milk and vegetable prices as well.

Ecology and habitat of breeding Northern Goshawks in the inland Pacific Northwest: A summary of research in the 1990s

USGS Publications Warehouse

DeStefano, S.; McGrath, M.T.; Daw, S.K.; Desimone, S.M.

2006-01-01

During the 1990s, we conducted research on the distribution, productivity, and habitat relationships of Northern Goshawks (Accipiter gentilis) in eastern Oregon and Washington. Our research was initiated primarily in response to concerns raised about the status of Northern Goshawks in the western US, and coincided with early attempts to list the species as threatened or endangered under the Endangered Species Act and the publication of management guidelines for goshawks in the southwestern US. To develop baseline information on the status, distribution, and habitat relationships of goshawks in eastside forests (i.e., east of the Cascade Mountain Range) in the Pacific Northwest, we established study areas on three national forests in eastern Oregon in 1992, adding a fourth study area in central Washington in 1994. We focused on the breeding season and nesting habitat because of its primary importance to goshawk ecology and the logistical feasibility of finding nests. Density of breeding pairs ranged from 0.03-0.09/100 ha, and annual productivity ranged from 0.3-2.2 young fledged/nest. Goshawks selected forest stands with trees of larger diameter and greater canopy closure for nesting than available in the landscape. Occasionally nests could be found in large trees in open-canopied stands. As distance increased from the nest site, forest type and structure became more heterogeneous and the prevalence of older-seral-stage forest declined. Dry or wet openings were present in most territories, often within close proximity to nest stands. Goshawks ate a variety of mammalian and avian prey. Mammal species made up a larger portion of prey biomass on two of the national forests, but avian species appeared to be more prevalent in the diet of goshawks in the most northern study area. We recommend that the existing management guidelines for goshawks in the Southwest form a basis for management in the inland Pacific Northwest, particularly with regard to nested spatial concepts

Nature of Persecutors and Their Behaviors in the Delusions of Schizophrenia: Changes between the 1990s and the 2000s.

Research suggests that the contents of delusions in schizophrenia are influenced by culture and social environment. However, few studies have investigated the chronological change of such delusions within a society. To investigate specifically the changes in the persecutory delusions of schizophrenia that have occurred over time, we compared the nature of the persecutors and their persecutory behaviors among inpatients with schizophrenia. All admissions to the psychiatric unit of Hanyang University Guri Hospital with discharge diagnoses of schizophrenia during two different five-year time frames (1996-2000 and 2006-2010) were reviewed. From their inpatient medical records, we investigated the descriptions of persecutors and their persecutory behaviors in the delusions of 124 patients (54 in the1990s and 72 in the 2000s). Overall, persecutory behaviors and nature of persecutors in the delusions of schizophrenia did not differ between the two time frames. However, subgroup analysis revealed that in women but not in men, rejection as a persecutory behavior was significantly higher in the 1990s (p<0.05). The ten-year time interval may be too short to find significant changes in delusional content in general. However, our additional finding in women may be a result of the tremendous change in status of Korean women during the last decade.

The European Association of Communication in Healthcare (EACH) Early Career Researchers Network (ECRN) aims are to (1) promote international collaboration among young investigators and (2) provide a support network for future innovative communication research projects. In October 2009, Miami, USA at a workshop facilitated by the ECRN at the International Conference on Communication in Healthcare (ICCH) hosted by the American Academy of Communication in Healthcare we explored common facilitators and challenges faced by early career researchers in health communication research. Attendees introduced themselves, their research area(s) of interest, and listed one facilitator and one barrier for their career development. EACH ECRN members then led a discussion of facilitators and challenges encountered in communication research projects and career development. We discussed potential collaboration opportunities, future goals, and activities. Having supportive collegial relationships, institutional support, job security, and funding are critical facilitators for early career investigators. Key challenges include difficulty with time management and prioritizing, limited resources, and contacts. International collaboration among early career researchers is a feasible and effective means to address important challenges, by increasing opportunities for professional support and networking, problem-solving, discussion of data, and ultimately publishing.

Objective The European Association of Communication in Healthcare (EACH) Early Career Researchers Network (ECRN) aims are to (1) promote international collaboration among young investigators and (2) provide a support network for future innovative communication research projects. In October 2009, Miami, USA at a workshop facilitated by the ECRN at the International Conference on Communication in Healthcare (ICCH) hosted by the American Academy of Communication in Healthcare we explored common facilitators and challenges faced by early career researchers in health communication research. Methods Attendees introduced themselves, their research area(s) of interest, and listed one facilitator and one barrier for their career development. EACH ECRN members then led a discussion of facilitators and challenges encountered in communication research projects and career development. We discussed potential collaboration opportunities, future goals, and activities. Results Having supportive collegial relationships, institutional support, job security, and funding are critical facilitators for early career investigators. Key challenges include difficulty with time management and prioritizing, limited resources, and contacts. Conclusion International collaboration among early career researchers is a feasible and effective means to address important challenges, by increasing opportunities for professional support and networking, problem-solving, discussion of data, and ultimately publishing. Practice Implications Future AACH-EACH Early Career Researcher Networks should continue to build collaborations by developing shared research projects, papers, and other scholarly products.

The Swedish labour market in the 1990s: the very last of the healthy jobs?

PubMed

Rostila, Mikael

2008-03-01

The economic recession in Sweden in the 1990s influenced several aspects of the labour market, including the psychosocial work environment. This study examined psychosocial working conditions in relation to self-reported ill-health in the 1990s by means of the job strain model. The study was based on two representative cross-sectional samples of Swedish employed men and women in 1991 (n=3,292) and 2000 (n=3,010), together with a panel of employees who were included for both years (n=1,953). The main outcome measures were psychological distress and self-rated poor health. The primary method used was logistic regression. The results suggested that although adverse psychosocial conditions increased during the 1990s, the association with health weakened. However, further analyses showed that poor health increased in most groups with various types of psychosocial conditions, and that reduced relative differences in poor health were discernible. Finally, a longitudinal analysis showed that long-term exposure to and experience of deteriorating psychosocial conditions was most detrimental for health at the end of the 1990s, once health status at baseline had been adjusted for. The increased prevalence of health problems among most groups with various psychosocial conditions during the 1990s, together with reduced relative differences in poor health, might make it more difficult for employers and policy-makers to direct health policies towards specific groups of employees, as the "healthy'' job seems to have disappeared. Another important inference of the results is that psychosocial working conditions seem to be causally related to health.

Such existing NASA/U.S. facilities and spacecraft as those of the Deep Space Network, VLA, and Arecibo are presently judged capable, at modest additional investment during the next five years, to acquire unique space science data, to generate mission planning data for missions to be launched in the early 1990s, and to evaluate and demonstrate communications and navigation technology for missions of the late 1990s and beyond. The more ambitious of these efforts will contribute the continuation of space research attractiveness for students, as well as furnish an important part of their scientific training.

A collaborative, evaluative review of qualitative research in palliative care published between 1990 and 1999 has been conducted. Nearly 30,000 articles in 48 journals from specialist palliative care, oncology, death studies, medicine, nursing, gerontology, health and the social sciences were examined. From these journals, 138 articles (0.5%) reporting qualitative research with a focus on palliative care in the context of death, dying or bereavement were identified. These articles were reviewed using a proforma designed by the group. This article describes the review process, and the following findings: the distribution of different forms of qualitative research in palliative care; the location of such papers; the focus of the research; and the research methodology and methods adopted.

Foul weather friends: big business and health care reform in the 1990s in historical perspective.

PubMed

Swenson, Peter; Greer, Scott

2002-08-01

Existing accounts of the Clinton health reform efforts of the early 1990s neglect to examine how the change in big business reform interests during the short period between the late 1980s and 1994 might have altered the trajectory of compulsory health insurance legislation in Congress. This article explores evidence that big employers lost their early interest in reform because they believed their private remedies for bringing down health cost inflation were finally beginning to work. This had a discouraging effect on reform efforts. Historical analysis shows how hard times during the Great Depression also aligned big business interests with those of reformers seeking compulsory social insurance. Unlike the present case, however, the economic climate did not quickly improve, and the social insurance reform of the New Deal succeeded. The article speculates, therefore, that had employer health expenditures not flattened out, continuing and even growing big business support might have neutralized small business and other opposition that contributed heavily to the failure of reform. Thus in light of the Clinton administration's demonstrated willingness to compromise with business on details of its plan, some kind of major reform might have succeeded.

Another decade of social scientific work on sex work: a review of research 1990-2000.

PubMed

Vanwesenbeeck, I

2001-01-01

The international, psychological and sociological research literature on prostitution from 1990 through 2000 is reviewed. The stage is set by scanning topics and perspectives in earlier writings. Then the research is discussed under the following headings: (a) HIV related research (HIV prevalence studies, factors in condom use, and prevention program evaluation); (b) workers' background and motivational issues (early victimization and connected factors, economic motives and connected factors); (c) work related issues (working routines, risks and stresses, and managing risk, work and identity); (d) research on clients, and (e) issues related to social and legal status. The literature is still much more about sex than it is about work. In addition, although an increasing number of authors have criticized the dominance of a deviance perspective over work perspectives on prostitution, the literature still reveals many features of stigmatization. For instance, the wrongs associated with sex work are all too often attributed to the nature of sex work itself instead of to the stigma attached to it or to specific negative circumstances. Likewise, the association between prostitution and negative features (in particular HIV and early victimization) is overwhelming, despite evidence that, for large groups of sex workers, these issues are of limited relevance. Generally, writers fail to adequately differentiate among types of sex workers. In particular, in relation to issues of health and well-being, differentiation among sex workers on the basis of specific features of their working situation (e.g., contexts, routines, relations, conditions) has hardly been studied and is recommended for the future.

Computerized structural mechanics for 1990's: Advanced aircraft needs

Viswanathan, A. V.; Backman, B. F.

1989-01-01

The needs for computerized structural mechanics (CSM) as seen from the standpoint of the aircraft industry are discussed. These needs are projected into the 1990's with special focus on the new advanced materials. Preliminary design/analysis, research, and detail design/analysis are identified as major areas. The role of local/global analyses in these different areas is discussed. The lessons learned in the past are used as a basis for the design of a CSM framework that could modify and consolidate existing technology and include future developments in a rational and useful way. A philosophy is stated, and a set of analyses needs driven by the emerging advanced composites is enumerated. The roles of NASA, the universities, and the industry are identified. Finally, a set of rational research targets is recommended based on both the new types of computers and the increased complexity the industry faces. Computerized structural mechanics should be more than new methods in structural mechanics and numerical analyses. It should be a set of engineering applications software products that combines innovations in structural mechanics, numerical analysis, data processing, search and display features, and recent hardware advances and is organized in a framework that directly supports the design process.

We use newly developed methods of measuring spatial segregation across a range of spatial scales to assess changes in racial residential segregation patterns in the 100 largest U.S. metropolitan areas from 1990 to 2000. Our results point to three notable trends in segregation from 1990 to 2000: 1) Hispanic-white and Asian-white segregation levels increased at both micro- and macro-scales; 2) black-white segregation declined at a micro-scale, but was unchanged at a macro-scale; and 3) for all three racial groups and for almost all metropolitan areas, macro-scale segregation accounted for more of the total metropolitan area segregation in 2000 than in 1990. Our examination of the variation in these trends among the metropolitan areas suggests that Hispanic-white and Asian-white segregation changes have been driven largely by increases in macro-scale segregation resulting from the rapid growth of the Hispanic and Asian populations in central cities. The changes in black-white segregation, in contrast, appear to be driven by the continuation of a 30-year trend in declining micro-segregation, coupled with persistent and largely stable patterns of macro-segregation.

Geier, David A; Kern, Janet K; Geier, Mark R

BACKGROUND This study evaluated the hypothesis that the 1999 recommendation by the American Academy of Pediatrics (AAP) and US Public Health Service (PHS) to reduce exposure to mercury (Hg) from Thimerosal in US vaccines would be associated with a reduction in the long-term risk of being diagnosed with autism. MATERIAL AND METHODS A two-phase assessment utilizing a case (n=73) -control (n=11,783) study in the Vaccine Adverse Event Reporting System (VAERS) database (for hypothesis generating) and a more rigorous, independent matched case (n=40) -control (n=40) study (hypothesis testing) was undertaken. RESULTS Analysis of the VAERS database using logistic regression revealed that the odds ratio (OR) for being an autism case in the VAERS database significantly decreased with a more recent year of vaccination in comparison to controls (OR=0.65) from 1998 to 2003. Sex-separated analyses revealed similar significant effects for males (OR=0.62) and females (OR=0.71). Analyses of the matched case-control data revealed, using the t-test statistic, that the mean date of birth among cases diagnosed with an autism spectrum disorder (ASD) (2000.5±1.2) was significantly more in the past than in controls (2001.1±1.3). Logistic regression also revealed that the OR for being diagnosed with ASD significantly decreased with a more recent date of birth in comparison to controls (OR=0.67) from 1998-2003. CONCLUSIONS This study reveals that the risk of autism during from the late1990s to early 2000s in the US significantly decreased with reductions in Hg exposure from Thimerosal-containing childhood vaccines, but future studies should examine this phenomenon in other US populations. Vaccine programs have significantly reduced the morbidity and mortality associated with infectious disease, but Thimerosal should be removed from all vaccines.

Objective Research suggests that the contents of delusions in schizophrenia are influenced by culture and social environment. However, few studies have investigated the chronological change of such delusions within a society. To investigate specifically the changes in the persecutory delusions of schizophrenia that have occurred over time, we compared the nature of the persecutors and their persecutory behaviors among inpatients with schizophrenia. Methods All admissions to the psychiatric unit of Hanyang University Guri Hospital with discharge diagnoses of schizophrenia during two different five-year time frames (1996-2000 and 2006-2010) were reviewed. From their inpatient medical records, we investigated the descriptions of persecutors and their persecutory behaviors in the delusions of 124 patients (54 in the1990s and 72 in the 2000s). Results Overall, persecutory behaviors and nature of persecutors in the delusions of schizophrenia did not differ between the two time frames. However, subgroup analysis revealed that in women but not in men, rejection as a persecutory behavior was significantly higher in the 1990s (p<0.05). Conclusion The ten-year time interval may be too short to find significant changes in delusional content in general. However, our additional finding in women may be a result of the tremendous change in status of Korean women during the last decade. PMID:23251194

County-level Estimates for Carbon Distribution in U.S. Croplands, 1990-2005

DOE Data Explorer

West, Tristram O. [Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States)

2008-01-01

Net Primary Productivity (NPP) for croplands can be estimated using a statistical method that includes factors for dry weight, harvest indices, and root:shoot ratios multiplied by yield data from the National Agricultural Statistics Service (NASS). This method has been documented and published by Prince et al. (2001), Hicke and Lobell (2004), and Hicke et al. (2004). We expanded this method by including factors for more crops and by using an estimated carbon content of 0.45 for agricultural crops to estimate (a) total net carbon uptake, (b) carbon in aboveground biomass, (c) carbon in belowground biomass, (d) carbon harvested and transported off site, and (e) the amount of carbon remaining on the surface following harvest. These five variables are included with their respective Federal Information Processing Standards (FIPS) codes for all counties in the contiguous U.S. from 1990-2005. A mean harvest efficiency of 0.95 was assumed across all crops. Total cropland NPP for the U.S. ranges from 378-527 Tg C yr^-1 within years 1990-2005, and total carbon harvested and removed ranges from 161-228 Tg C yr^-1 within years 1990-2005.

The changing nature of spacecraft operations: From the Vikings of the 1970's to the great observatories of the 1990's and beyond

NASA Technical Reports Server (NTRS)

Ledbetter, Kenneth W.

1992-01-01

Four trends in spacecraft flight operations are discussed which will reduce overall program costs. These trends are the use of high-speed, highly reliable data communications systems for distributing operations functions to more convenient and cost-effective sites; the improved capability for remote operation of sensors; a continued rapid increase in memory and processing speed of flight qualified computer chips; and increasingly capable ground-based hardware and software systems, notably those augmented by artificial intelligence functions. Changes reflected by these trends are reviewed starting from the NASA Viking missions of the early 70s, when mission control was conducted at one location using expensive and cumbersome mainframe computers and communications equipment. In the 1980s, powerful desktop computers and modems enabled the Magellan project team to operate the spacecraft remotely. In the 1990s, the Hubble Space Telescope project uses multiple color screens and automated sequencing software on small computers. Given a projection of current capabilities, future control centers will be even more cost-effective.

Have I Been a Data Scientist from the Start? Parallels from the Geographic Information Science Community in the Early 1990s

NASA Astrophysics Data System (ADS)

Wright, D. J.

2013-12-01

In the early 1990s the author came of age as the technology driving the geographic information system or GIS was beginning to successfully 'handle' geospatial data at a range of scales and formats, and a wide array of information technology products emerged from an expanding GIS industry. However, that small community struggled to reflect the diverse research efforts at play in understanding the deeper issues surrounding geospatial data, and the impediments to that effective use of that data. It was from this need that geographic information science or GIScience arose, to ensure in part that GIS did not fall into the trap of being a technology in search of applications, a one-time, one-off, non-intellectual 'bag of tricks' with no substantive theory underpinning it, and suitable only for a static period of time (e.g., Goodchild, 1992). The community has since debated the issue of "tool versus science' which has also played a role in defining GIS as an actual profession. In turn, GIS has contributed to "methodological versus substantive" questions in science, leading to understandings of how the Earth works versus how the Earth should look. In the author's experience, the multidimensional structuring and scaling data, with integrative and innovative approaches to analyzing, modeling, and developing extensive and spatial data from selected places on land and at sea, have revealed how theory and application are in no way mutually exclusive, and it may often be application that advances theory, rather than vice versa. Increasingly, both the system and science of geographic information have welcomed strong collaborations among computer scientists, information scientists, and domain scientists to solve complex scientific questions. As such, they have paralleled the emergence and acceptance of "data science." And now that we are squarely in an era of regional- to global-scale observation and simulation of the Earth, produce data that are too big, move too fast, and do not

A midpoint assessment of the American Cancer Society challenge goal to halve the U.S. cancer mortality rates between the years 1990 and 2015.

The American Cancer Society has challenged the U.S. to reduce cancer mortality rates 50% over the 25 years from 1990 to 2015. The current report is an analysis and commentary on progress toward that goal through 2002, the midpoint of the challenge period. Cancer mortality rates were examined from 1990 through 2002, and projections to the Year 2015 were made. Cancer deaths that were prevented or deferred by the declining death rates were expressed as the difference between the observed and projected numbers of deaths and the numbers that would have been observed over that period had the 1990 death rates persisted. Since 1990, cancer mortality rates have been declining in the U.S. by approximately 1% per year. Trends especially have been favorable for cancers of the breast, prostate, and colorectum and for lung cancer among men. Should this rate of decline continue over the coming decade, death rates from cancer will be approximately 23% lower in the Year 2015 than they were in 1990, and approximately 1.8 million deaths from cancer will have been prevented or deferred. At this midpoint of the 25-year challenge period, it appears that fully reaching the goal will require substantial breakthroughs in cancer early detection and/or in cancer therapy. Between now and 2015, however, many more cancer deaths can be averted by concerted action to control tobacco and obesity, by redoubling efforts in mammography and colorectal screening, and by enacting policies to close gaps in access to cancer detection and treatment services.

Did the elimination of lead from petrol reduce crime in the USA in the 1990s?

PubMed Central

Hall, Wayne

2013-01-01

This article assesses the evidence for the hypothesis that a decline in all types of crime since the early 1990s in the USA was a consequence of removing lead from petrol between 1975 and 1985. It describes ecological and econometric studies that have generally but not always found correlations between lead exposures in childhood and some types of crime 20 years later; a small number of epidemiological studies that have found a dose-response relationship between lead exposure in childhood and self-reported and officially recorded criminal offences in young adulthood; and evidence for the biological plausibility of a causal relationship. Lead exposure in childhood may have played a small role in rising and falling crime rates in the USA but it is unlikely to account for the very high percentage of the decline suggested by the ecological studies. The major anomaly in the evidence is that the associations reported in ecological studies are much stronger (explaining 56-90% of the variation in crime rates) than the weaker relationships found in the cohort studies (that typically explain less than 1% of the variance in offending).  Suggestions are made for research that will better assess the contribution that reduced lead exposure has made to declining crime rates in the USA.

Bathymetry of Stevens Creek and Neal Shoals reservoirs, South Carolina, 1990

USGS Publications Warehouse

Stringfield, W.J.

1995-01-01

Stevens Creek Reservoir and Neal Shoals Reservoir are located in the Piedmont Province of South Carolina (fig. 1). The primary purposes for the reservoirs are hydroelectric power generation and recreational activities. Because there has been no bottom surveys of these reservoirs since they were formed in the early 1900's, there is concern about the decrease in reservoir volumes due to sedimen- tation. An investigation was begun in 1990 by the U.S. Geological Survey (USGS) in cooperation with the South Carolina Department of Natural Resources, Water Resources Division to provide information on present water depths, on areas of rapid-sediment deposition, and on changes in lake volume. This report documents the bathymetric surveys made of Stevens Creek and Neal Shoals Reservoirs during 1990 and provides maps that depict the depth of each reservoir.

Lalwaney, N. S.; Linse, V. D.

1985-01-01

Explosive bonding is a unique joining process with the serious potential to produce composite materials capable of fulfilling many of the high performance materials capable of fulfilling many of the high performance materials needs of the 1990's. The process has the technological versatility to provide a true high quality metallurgical compatible and incompatible systems. Metals routinely explosively bonded include a wide variety of combinations of reactive and refractory metals, low and high density metals and their alloys, corrosion resistant and high strength alloys, and common steels. The major advantage of the process is its ability to custom design and engineer composites with physical and/or mechanical properties that meet a specific or unusual performance requirement. Explosive bonding offers the designer unique opportunities in materials selection with unique combinations of properties and high integrity bonds that cannot be achieved by any other metal joining process. The process and some applications are discussed.

Results of Chilean water markets: Empirical research since 1990

NASA Astrophysics Data System (ADS)

Bauer, Carl J.

2004-09-01

Chile's free-market Water Code turned 20 years old in October 2001. This anniversary was an important milestone for both Chilean and international debates about water policy because Chile has become the world's leading example of the free-market approach to water law and water resources management, the textbook case of treating water rights not merely as private property but also as a fully marketable commodity. The predominant view outside of Chile is that Chilean water markets and the Chilean model of water management have been a success, and this perception has encouraged other countries to follow Chile's lead in water law reform. Much of the debate about Chilean water markets, however, has been based more on theoretical or political beliefs than on empirical study. This paper reverses that emphasis by reviewing the evolution of empirical research about these markets since 1990, when Chile returned to democratic government after 16 years of military rule. During the period since 1990, understanding of how Chilean water markets have worked in practice has gradually improved. There have been two major trends in this research: first, a gradual shift from exaggerated claims of the markets' success toward more balanced assessments of mixed results and, second, a heavy emphasis on the economics of water rights trading with very little attention given to the Water Code's impacts on social equity, river basin management, environmental protection, or resolution of water conflicts. The analysis in this study is qualitative and interdisciplinary, combining law, economics, and institutions.

Sensitizing events as trigger for discursive renewal and institutional change in Flanders’ environmental health approach, 1970s-1990s

PubMed Central

2013-01-01

Background Sensitizing events may trigger and stimulate discursive renewal. From a discursive institutional perspective, changing discourses are the driving force behind the institutional dynamics of policy domains. Theoretically informed by discursive institutionalism, this article assesses the impact of a series of four sensitizing events that triggered serious environmental health concerns in Flanders between the 1970s till the 1990s, and led onto the gradual institutionalization of a Flemish environmental health arrangement. Methods The Policy Arrangement Approach is used as the analytical framework to structure the empirical results of the historical analysis based on document analysis and in-depth interviews. Results Until the 1990s, environmental health was characterized as an ad hoc policy field in Flanders, where agenda setting was based on sensitizing events – also referred to as incident-driven. Each of these events contributed to a gradual rethinking of the epistemological discourses about environmental health risks and uncertainties. These new discourses were the driving forces behind institutional dynamics as they gradually resulted in an increased need for: 1) long-term, policy-oriented, interdisciplinary environmental health research; 2) policy coordination and integration between the environmental and public health policy fields; and 3) new forms of science-policy interactions based on mutual learning. These changes are desirable in order to detect environmental health problems as fast as possible, to react immediately and communicate appropriately. Conclusions The series of four events that triggered serious environmental health concerns in Flanders provided the opportunity to rethink and re-organize the current affairs concerning environmental health and gradually resulted into the institutionalization of a Flemish environmental health arrangement.

[Review of the gender research in cross-cultural psychology since 1990: conceptual definitions and methodology].

PubMed

Suzuki, Atsuko

2004-06-01

A review of the cross-cultural research on gender in psychology since 1990 reveals (1) conceptual confusion of the definitions of sex, gender, man, and woman; (2) diversification, refinement, reification, and a problem-solving orientation in the research topics; and (3) the possibility of the elucidation of the psychological sex-difference mechanism in relation to the biological sex differences. A comparison of 1990 and 2000 cross-cultural psychological articles published in "Sex Roles" found that overall, the research is Western-centered and some methodological problems remain to be solved concerning the measures and the sampling. These findings lead to the following suggestions for cross-cultural research on gender to resolve the problems and contribute to the development of psychology in general: (1) use of an operational definition for conceptual equivalence; (2) conducting more etic-approach research; (3) avoiding ethnocentric or androcentric research attitudes; (4) use of a theoretical framework; (5) strict examination of methodologies; and (6) examination of the specific context of participants in terms of cultural diversity, dynamics of husband-wife relationships, and relationships with husbands and fathers.

1992-01-01

The U.S. Geological Survey, using NOAA-ll Advanced Very High Resolution Radiometer (AVHRR) 1-km data, has produced a time series of 19 biweekly maximum normalized difference vegetation index (NDV!) composites of the conterminous United States for the 1990 growing season. Each biweekly composite included data from approximately 20 calibrated and georegistered daily overpasses. The output is a data set which includes all five calibrated AVHRR channels, NOV! values, three satellite/solar viewing angles, and date of observation pointer for each biweekly composite. The data set is intended for assessing seasonal variations in vegetation condition and provides a foundation for studying long-term changes in vegetation resulting from human interactions or global climate alterations.

1991-01-01

A new flight research vehicle, the Rotorcraft-Aircrew System Concepts Airborne Laboratory (RASCAL), is being developed by the U.S. Army and NASA at ARC. The requirements for this new facility stem from a perception of rotorcraft system technology requirements for the next decade together with operational experience with the Boeing Vertol CH-47B research helicopter that was operated as an in-flight simulator at ARC during the past 10 years. Accordingly, both the principal design features of the CH-47B variable-stability system and the flight-control and cockpit-display programs that were conducted using this aircraft at ARC are reviewed. Another U.S Army helicopter, a Sikorsky UH-60A Black Hawk, was selected as the baseline vehicle for the RASCAL. The research programs that influence the design of the RASCAL are summarized, and the resultant requirements for the RASCAL research system are described. These research programs include investigations of advanced, integrated control concepts for achieving high levels of agility and maneuverability, and guidance technologies, employing computer/sensor-aiding, designed to assist the pilot during low-altitude flight in conditions of limited visibility. The approach to the development of the new facility is presented and selected plans for the preliminary design of the RASCAL are described.

2007-01-01

Historical land-use and land-cover data, available from the U.S. Geological Survey (USGS) for the conterminous United States and Hawaii, have been enhanced for use in geographic information systems (GIS) applications. The original digital data sets were created by the USGS in the late 1970s and early 1980s and were later converted by USGS and the U.S. Environmental Protection Agency (USEPA) to a geographic information system (GIS) format in the early 1990s. These data were made available on USEPA's Web site since the early 1990s and have been used for many national applications, despite minor coding and topological errors. During the 1990s, a group of USGS researchers made modifications to the data set for use in the National Water-Quality Assessment Program. These edited files have been further modified to create a more accurate, topologically clean, and seamless national data set. Several different methods, including custom editing software and several batch processes, were applied to create this enhanced version of the national data set. The data sets are included in this report in the commonly used shapefile and Tagged Image Format File (TIFF) formats. In addition, this report includes two polygon data sets (in shapefile format) representing (1) land-use and land-cover source documentation extracted from the previously published USGS data files, and (2) the extent of each polygon data file.

States and the politics of incrementalism: health policy in Wisconsin during the 1990s.

PubMed

Sparer, Michael S

2004-04-01

Wisconsin officials during the 1990s seemed poised to enact innovative and comprehensive health care reform. During that era, an ambitious, popular, and reform-minded governor led the state. The state had an unusually professional legislature. The state's economy was strong. Even with these advantages, however, the report card on the state's efforts is mixed. The state enacted a fairly modest set of reforms that were financed largely by the federal government and subject to extensive federal oversight. The Wisconsin story thus seems to be about the politics of incrementalism. But while critics of incrementalist politics point out that the number of uninsured continues to grow, the catalytic federalism witnessed in Wisconsin in the 1990s may well be the best model for implementing health care reform.

Children’s early helping in action: Piagetian developmental theory and early prosocial behavior

PubMed Central

Hammond, Stuart I.

2014-01-01

After a brief overview of recent research on early helping, outlining some central problems, and issues, this paper examines children’s early helping through the lens of Piagetian moral and developmental theory, drawing on Piaget’s “Moral Judgment of the Child” (Piaget, 1932/1997), “Play, Dreams, and Imitation in Childhood” (Piaget, 1945/1951), and the “Grasp of Consciousness” (Piaget, 1976). Piaget refers to a level of moral development in action that precedes heteronomous and autonomous moral reasoning. This action level allows children to begin to interact with people and objects. In his later work, Piaget explores the gradual construction of understanding from this activity level. Taken together, these elements of Piagetian theory provide a promising conceptual framework for understanding the development of early helping. PMID:25101027

International collaboration is becoming increasingly vital as the emphasis on unmet need for mental health across cultures and nations grows. Opportunities exist for early career researchers to engage in international collaboration. However, little information is provided about such opportunities in most current psychology training models. The authors are early career researchers in psychology from U.S. and Australia who have developed a collaborative relationship over the past two years. Our goal is to increase awareness of funding opportunities to support international research and to highlight the benefits and challenges associated with international collaboration based on our experience.

Global Research Trends on Early-Life Feeding Practices and Early Childhood Caries: a Systematic Review

PubMed Central

Cheng, Ashley

2014-01-01

Objective Describe the epidemiologic literature related to early-life feeding practices and early childhood caries (ECC) with regard to publication attributes and trends in these attributes over time. Methods Systematic literature review including electronic and manual searches (in BIOSIS, CINAHL, Cochrane Library, LILACS, MEDLINE, Web of Science, and WHOLIS), covering the years 1990–2013. Attributes of publications meeting a priori inclusion criteria were abstracted and organized by global region and trends over time. Attributes included country of origin and study design of included publications and age and caries prevalence of the populations studied. Results 244 publications drawn from 196 independent study populations were included. The number of publications and the countries represented increased over time, although some world regions remained underrepresented. Most publications were cross sectional (75%); while this percentage remained fairly constant over time, the percentage of studies to account for confounding factors increased. Publications varied with respect to the caries experience and age range of children included in each study. Conclusions Publication productivity regarding feeding practices and ECC research has grown, but this growth has not been evenly distributed globally. Individual publication attributes (i.e. methods and context) can differ significantly and should be considered when interpreting and synthesizing the literature. PMID:25328911

A literature review of studies of depression and treatment outcomes among U.S. College students since 1990.

PubMed

Miller, Elissa J; Chung, Henry

2009-09-01

The mental health of U.S. college students is a growing public health concern. Particularly alarming is the prevalence of depression and risk of suicide in this cohort. A literature review of PsycINFO, MEDLINE, and CINAHL databases was conducted in order to identify and evaluate depression and treatment outcomes among U.S. college students since 1990. Four studies documenting depression and treatment outcomes among U.S. college students were identified and reviewed. Although research on the depression and treatment outcomes among U.S. college students exists, it is scarce and inconsistent, with varying inclusion and exclusion criteria and measurement of depression severity and its treatment. Future work needs to focus on the development of reasonable benchmarks of depression and treatment outcomes in the college population and the integration of such outcome data into college mental health practice.

Surman, Geraldine; Newdick, Helen; Johnson, Ann

2003-07-01

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.

Educational inequalities in young-adult mortality between the 1990s and the 2000s: regional differences in Belgium.

De Grande, Hannelore; Vandenheede, Hadewijch; Deboosere, Patrick

2015-01-01

This study addresses educational inequalities in young-adult mortality between the 1990s and the 2000s by comparing trends in the three different regions in Belgium stratified by sex. Social inequalities in mortality are of major concern to public health but are rarely studied at young ages. Substantial health differences have been found between the Flemish (FR) and Walloon region (WR) concerning (healthy) life expectancy and avoidable mortality, but little is known about regional differentials in young-adult mortality, and comparisons with the Brussels-Capital Region (BCR) have thus far never been made. Data are derived from record linkage between the Belgian censuses of 1991 and 2001 and register data on death and emigration for the periods 01/03/1991-01/03/1999 and 01/10/2001-01/10/2009. Analyses are restricted to young adults aged 25 to 34 years at the moment of each of the censuses. Absolute (directly standardized mortality rates (ASMRs)) and relative (mortality rate ratio using Poisson regression) measures were calculated. There is a significant drop in young-adult mortality between the 1990s and the 2000s in all regions and both sexes, with the strongest decline in the BCR (e.g. ASMR of men declined from 165.6 [151.1-180.1] per 100,000 person years to 73.8 [88.3-98.3]). The mortality rates remain highest in the WR in the 2000s Between the 1990s and the 2000s, a remarkable change in the educational distribution occurred as well, with much lower proportions of primary educated in all regions in the 2000s in favour of higher proportions in all other educational levels, especially in higher education. All educational groups show lower mortality over time, except for lower educated men in the FR. There is a positive evolution towards lower mortality among the young-adult Belgian population. The WR trails behind in this evolution, which calls for tailored preventive actions. Educational inequalities are marked in all regions and time periods. A more general

ElarmS Earthquake Early Warning System 2016 Performance and New Research

NASA Astrophysics Data System (ADS)

Chung, A. I.; Allen, R. M.; Hellweg, M.; Henson, I. H.; Neuhauser, D. S.

2016-12-01

The ElarmS earthquake early warning system has been detecting earthquakes throughout California since 2007. It is one of the algorithms that contributes to the West Coast ShakeAlert, a prototype earthquake early warning system being developed for the US West Coast. ElarmS is also running in the Pacific Northwest, and in Israel, Chile, Turkey, and Peru in test mode. We summarize the performance of the ElarmS system over the past year and review some of the more problematic events that the system has encountered. During the first half of 2016 (2016-01-01 through 2016-07-21), ElarmS successfully alerted on all events with ANSS catalog magnitudes M>3 in the Los Angeles area. The mean alert time for these 9 events was just 4.84 seconds. In the San Francisco Bay Area, ElarmS detected 26 events with ANSS catalog magnitudes M>3. The alert times for these events is 9.12 seconds. The alert times are longer in the Bay Area than in the Los Angeles area due to the sparser network of stations in the Bay Area. 7 Bay Area events were not detected by ElarmS. These events occurred in areas where there is less dense station coverage. In addition, ElarmS sent alerts for 13 of the 16 moderately-sized (ANSS catalog magnitudes M>4) events that occurred throughout the state of California. One of those missed events was a M4.5 that occurred far offshore in the northernmost part of the state. The other two missed events occurred inland in regions with sparse station coverage. Over the past year, we have worked towards the implementation of a new filterbank teleseismic filter algorithm, which we will discuss. Other than teleseismic events, a significant cause of false alerts and severely mislocated events is spurious triggers being associated with triggers from a real earthquake. Here, we address new approaches to filtering out problematic triggers.

Microgravity Research: A Retrospective of Accomplishments

NASA Astrophysics Data System (ADS)

Voorhees, Peter

2005-03-01

During the early days of human spaceflight U.S. National Aeronautics and Space Administration (NASA) began giving researchers the ability to perform experiments under extremely low gravity conditions (microgravity). Early microgravity experiments were rudimentary and discovery driven. The limitations of such an approach were clear and in the early 1990s, NASA broadened its program significantly beyond those experiments that were destined to be flown to include a ground- based program that contained both experimental and theoretical investigations. The ground-based program provided a source of carefully designed microgravity experiments. This led to the program in the Physical Sciences Division that involved research in, for example, fluids, materials and low temperature physics. The impact of the microgravity research program has been the focus of a recent National Research Council report titled “Assessment of Directions in Microgravity and Physical Sciences Research at NASA.” We found that there have been numerous high impact ground-based and flight investigations. For example, NASA funding has been instrumental in elucidating the nature of surface-tension-driven fluid flows, dendritic crystal growth and the thermodynamics of phase transitions near critical points. Using this report as a basis, a discussion of the impact of microgravity research on the fields in which it is a part will be given.

Clandestine existences and secret research: eliminating official discrimination in the Canadian military and going public in academia.

Poulin, Carmen; Gouliquer, Lynne

2012-01-01

The 1990s was a notable decade for lesbians and gays in the Canadian military. Two important changes were the 1992 elimination of the official policy permitting discrimination against homosexual service members, and the 1996 introduction of benefits to same-sex partners. These changes radically influenced the psychological day-to-day reality of lesbian and gay military members. Yet, given the military culture, lesbian and gay members only began to come out in significant numbers at the turn of the century. This article presents an overview of our experience with researching the history of lesbians and gays in the Canadian military during the late 1990s and early years of the new century. It reveals the early clandestine nature of our research, and recounts some of the trials, tribulations, resistance, and successes we encountered when dealing with ethics boards and funding sources. It also describes our relationship with the media and how the military actively took steps to stall our efforts. We draw parallels between our experiences as researchers, and those of the lesbian service-members we were interviewing.

Researchers at the Marshall Space Flight Center (MSFC) have designed, fabricated, and tested the first solar thermal engine, a non-chemical rocket engine that produces lower thrust but has better thrust efficiency than a chemical combustion engine. This photograph shows components for the thermal propulsion engine being laid out prior to assembly. MSFC turned to solar thermal propulsion in the early 1990s due to its simplicity, safety, low cost, and commonality with other propulsion systems. As part of MSFC's Space Transportation Directorate, the Propulsion Research Center serves as a national resource for research of advanced, revolutionary propulsion technologies. The mission is to move the Nation's capabilities beyond the confines of conventional chemical propulsion into an era of aircraft-like access to Earth-orbit, rapid travel throughout the solar system, and exploration of interstellar space.

The Environmental Protection Department/Environmental Monitoring Section (EPD/EMS) administers the Savannah River Site`s (SRS) Groundwater Monitoring Program. During third quarter 1990 (July through September) EPD/EMS conducted routine sampling of monitoring wells and drinking water locations. EPD/EMS established two sets of flagging criteria in 1986 to assist in the management of sample results. The flagging criteria do not define contamination levels; instead they aid personnel in sample scheduling, interpretation of data, and trend identification. The flagging criteria are based on detection limits, background levels in SRS groundwater, and drinking water standards. All analytical results from third quarter 1990 are listed in thismore » report, which is distributed to all site custodians. One or more analytes exceeded Flag 2 in 87 monitoring well series. Analytes exceeded Flat 2 for the first since 1984 in 14 monitoring well series. In addition to groundwater monitoring, EPD/EMS collected drinking water samples from SRS drinking water systems supplied by wells.

Biopharmaceutical Innovation System in China: System Evolution and Policy Transitions (Pre-1990s-2010s)

PubMed Central

Hu, Hao; Chung, Chao-Chen

2015-01-01

Background: This article sets up the initial discussion of the evolution of biopharmaceutical innovation in China through the perspective of sectoral innovation system (SIS). Methods: Two data sources including archival documentary data and field interviews were used in this study. Archival documentary data was collected from China Food and Drug Administration (CFDA) and Chinese National Knowledge Infrastructure (CNKI). In addition, industrial practitioners and leading researchers in academia were interviewed. Results: Biopharmaceutical in China was established through international knowledge transfer. The firms played more active role in commercializing biopharmaceutical in China though universities and research institutes were starting to interact with local firms and make contribution to biopharmaceutical industrialization. The transition of the Chinese government’s policies continuously shapes the evolution of biopharmaceutical sector. Policies have been dramatic changes before and after 1980s to encourage developing biopharmaceutical as a competitive industry for China. Conclusion: A SIS for biopharmaceutical has been shaped in China. However, currently biopharmaceutical is still a small sector in China, and for the further growth of the industry more synthetic policies should be implemented. Not only the policy supports towards the research and innovation of biopharmaceuticals in the early stage of development should be attended, but also commercialization of biopharmaceutical products in the later stage of sales.

For this study, the authors analyzed the contents of 16 psychology journals for the presence of empirical articles on African Americans, Latinos, Asians, and Native Americans during the period ranging from 1990 to 1999. In 6 APA journals, there was a low percentage (4.7%) of such articles. African Americans were the most studied ethnic group. Data collected for this study also indicated that minority research has been increasing more in non-APA journals than in APA journals. In both APA and non-APA journals, counseling-oriented journals had higher percentages of minority articles than did journals of other subdisciplines. Possible explanations, consequences, and suggestions for future research are discussed.

Investigation into the earliest signs of autism in infants has become a significant sub-field of autism research. This work invokes specific ethical concerns such as use of 'at-risk' language, communicating study findings to parents and the future perspective of enrolled infants when they reach adulthood. This study aimed to ground this research field in an understanding of the perspectives of members of the autism community. Following focus groups to identify topics, an online survey was distributed to autistic adults, parents of children with autism and practitioners in health and education settings across 11 European countries. Survey respondents (n = 2317) were positively disposed towards early autism research, and there was significant overlap in their priorities for the field and preferred language to describe infant research participants. However, there were also differences including overall less favourable endorsement of early autism research by autistic adults relative to other groups and a dislike of the phrase 'at-risk' to describe infant participants, in all groups except healthcare practitioners. The findings overall indicate that the autism community in Europe is supportive of early autism research. Researchers should endeavour to maintain this by continuing to take community perspectives into account. © The Author(s) 2016.

Kleimenhagen, A; Naidu, G M; Pillari, G D

1994-01-01

National health care expenditures are rising rapidly, bringing on a health care financing crisis. For this reason, it is useful to see how hospitals are facing the price issues of the 1990's. This study examines the price strategies hospitals follow and analyzes their observations on price sensitivity and payer mix. The results clearly show that hospitals have not given much attention to the pricing variable. The study suggests that marketing and finance will have to work closely together in developing future pricing strategies.

The Evolving Law of Disputed Relocation: constructing inner-city renewal practices in Shanghai, 1990-2005.

PubMed

Shih, Mi

2010-01-01

The forceful pursuit of inner-city renewal in Shanghai since the early 1990s has to a great extent achieved spatial modernization, but at the same time it has given rise to increasing conflicts over residential relocation. Using law as a prism through which to examine the dialectic relationship between renewal practices and disputed relocation, this article argues that the series of unprecedented enactments in law that have taken place during this period have both paved the way for real estate market expansion and been a significant source of relocation disputes in Shanghai. Rather than viewing law as simply given and determinate, the article traces the regulatory regime's codification of property practices as a means of actively responding to the requirements of the real estate market. Under large-scale renewal practices, residents' legal rights of "return settlement" (huiban) in inner-city areas were largely denied in the early 1990s, before being effectively abolished by the adoption of monetary compensation for displacement in the 2000s. The evolving law on property practices has greatly shaped the process of disputed relocation while simultaneously posing a potential challenge to China's use of law for market-oriented development.

Stereotypes of the elderly in U.S. television commercials from the 1950s to the 1990s.

PubMed

Miller, Darryl W; Leyell, Teresita S; Mazachek, Juliann

2004-01-01

Critics have charged that American advertisers have often portrayed the elderly with negative stereotypes. These negative portrayals, they suggest, not only offend elderly consumers but also contribute to ageism. This study examined whether American advertisers have indeed used a great deal of negative stereotyping of the elderly, as the critics have suggested. Employing a concept of stereotypes found in cognitive psychology, the authors examined trends in the portrayal of the elderly in television commercials produced in the United States from the 1950s through the 1990s. Results of the study do not support the contentions of the critics. Very little negative stereotyping was discovered. Analysis indicated trends in the appearance of several positive stereotypes, and differences in the stereotyping of gender groups and age segments within the elderly group. Results are interpreted from both marketing and social science perspectives.

Over the past 25 years, there has been growing recognition of the importance of studying the Ethical, Legal and Social Implications (ELSI) of genetic and genomic research. A large investment into ELSI research from the National Institutes of Health (NIH) Human Genomic Project budget in 1990 stimulated the growth of this emerging field; ELSI research has continued to develop and is starting to emerge as a field in its own right. The evolving subject matter of ELSI research continues to raise new research questions as well as prompt re-evaluation of earlier work and a growing number of scholars working in this area now identify themselves as ELSI scholars rather than with a particular discipline. Due to the international and interdisciplinary nature of ELSI research, scholars can often find themselves isolated from disciplinary or regionally situated support structures. We conducted a workshop with Early Career Researchers (ECRs) in Oxford, UK, and this paper discusses some of the particular challenges that were highlighted. While ELSI ECRs may face many of the universal challenges faced by ECRs, we argue that a number of challenges are either unique or exacerbated in the case of ELSI ECRs and discuss some of the reasons as to why this may be the case. We identify some of the most pressing issues for ELSI ECRs as: interdisciplinary angst and expertise, isolation from traditional support structures, limited resources and funding opportunities, and uncertainty regarding how research contributions will be measured. We discuss the potential opportunity to use web 2.0 technologies to transform academic support structures and address some of the challenges faced by ELSI ECRs, by helping to facilitate mentoring and support, access to resources and new accreditation metrics. As our field develops it is crucial for the ELSI community to continue looking forward to identify how emerging digital solutions can be used to facilitate the international and interdisciplinary

Injuries resulting from car surfing--United States, 1990-2008.

PubMed

2008-10-17

"Car surfing" is a term introduced in the mid-1980s to describe a thrill-seeking activity that involves riding on the exterior of a moving motor vehicle while it is being driven by another person. Although reports of car-surfing injuries have been published in the United States, no study to date has analyzed these events from a national perspective. Because traditional public health datasets do not collect morbidity or mortality data on this practice, CDC searched U.S. newspaper reports to provide an initial characterization of car-surfing injuries on a national scale. That analysis identified 58 reports of car-surfing deaths and 41 reports of nonfatal injury from 1990 through August 2008. Most reports of car-surfing injuries came from newspapers in the Midwest and South (75%), and most of the injuries were among males (70%) and persons aged 15-19 years (69%). The first identified newspaper reports about car-surfing injuries were published in the early 1990s, and new reports have been published every year since then. Parents and teens should be aware of the potentially lethal consequences of car surfing, which can occur even at low vehicle speeds, sometimes resulting from unanticipated movements of the vehicle, such as swerving or braking.

The changing nature of nurses' job satisfaction: an exploration of sources of satisfaction in the 1990s.

PubMed

Tovey, E J; Adams, A E

1999-07-01

This paper focuses on the changing nature of nurses' job satisfaction. It compares the major sources of satisfaction and dissatisfaction experienced by acute ward nurses in the English National Health Service (NHS) in the early 1990s, with sources identified in previous research. In the light of findings from a pilot study, the suitability of existing research approaches and measurement tools for portraying nurses' contemporary work experiences is examined. The study comprised content analysis of a random sample of 130 nurses' comments about ward organizational issues, collected as part of a national survey. Findings suggest that new measurement tools need to be developed, because new sources of satisfaction and dissatisfaction emerged, directly associated with change arising out of the introduction of the NHS internal market. These include pressures associated with new roles, role conflict, lack of job security, 'tight' resources, using new technology, a perceived lowering of standards of patient care, coping with increased amounts of paperwork, and the experience of working in a rapidly and constantly changing environment. Findings also suggest that the nature of nurses' job satisfaction is increasingly being shaped by their position within the organization, denoted by clinical grade, and the organizational culture of individual NHS Trusts. Ward leaders experience dissatisfaction as a result of role conflict and strain, while nurses of lower clinical grades are increasingly concerned with managerial and resource constraints on their ability to provide good quality care. Nurses' satisfaction with management and morale were found to be significantly different between NHS Trusts. While findings may be specific to England, it is argued that they have relevance for the wider, international nursing community. This is because developing an understanding of the changing nature of nurses' job satisfaction may help to resolve recruitment and retention problems.

In ancient times, a supernatural understanding of the syndrome of lumbar radiculopathy often involved demonic forces vexing the individual with often crippling pain. The ancient Greeks and Egyptians began to take a more naturalistic view and, critically, suspected a relationship between lumbar spinal pathology and leg symptoms. Relatively little then changed for those with sciatica until the classic works by Cotugno and Kocher arrived in the late 18th century. Early lumbar canal explorations were performed in the late 1800s and early 1900s by MacEwen, Horsley, Krause, Taylor, Dandy, and Cushing, among others. In these cases, when compressive pathologies were found and removed, the lesions typically were (mis-)identified as enchondromas or osteochondritis dissecans. To better understand the history, learn more about the first treatments of lumbar disc herniation, and evaluate the impact of the early influences on modern spine practice, searches of PubMed and Embase were performed using the search terms discectomy, medical history, lumbar spine surgery, herniated disc, herniated nucleus pulposus, sciatica, and lumbar radiculopathy. Additional sources were identified from the reference lists of the reviewed papers. Many older and ancient sources including De Ischiade Nervosa are available in English translations and were used. When full texts were not available, English abstracts were used. The first true, intentional discectomy surgery was performed by Mixter and Barr in 1932. Early on, a transdural approach was favored. In 1938, Love described the intralaminar, extradural approach. His technique, although modified with improved lighting, magnification, and retractors, remains a staple approach to disc herniations today. Other modalities such as chymopapain have been investigated. Some remain a part of the therapeutic armamentarium, whereas others have disappeared. By the 1970s, CT scanning after myelography markedly improved the clinical evaluation of patients with

O'Connell, Allan F.

2015-01-01

Camera traps — remotely activated cameras with infrared sensors — first gained measurable popularity in wildlife conservation in the early 1990s. Today, they’re used for a variety of activities, from species-specific research to broad-scale inventory or monitoring programs that, in some cases, attempt to detect biodiversity across vast landscapes. As this modern tool continues to evolve, it’s worth examining its uses and benefits for wildlife management and conservation.

In the military field, the performance evaluation of early-warning aircraft deployment or construction is always an important problem needing to be explored. As an effective approach of enterprise management and performance evaluation, Balanced Score Card (BSC) attracts more and more attentions and is studied more and more widely all over the world. It can also bring feasible ideas and technical approaches for studying the issue of the performance evaluation of the deployment or construction of early-warning aircraft which is the important component in early-warning detection system of systems (SoS). Therefore, the deep explored researches are carried out based on the previously research works. On the basis of the characteristics of space exploration and aerial detection effectiveness of early-warning detection SoS and the cardinal principle of BSC are analyzed simply, and the performance evaluation framework of the deployment or construction of early-warning aircraft is given, under this framework, aimed at the evaluation issue of aerial detection effectiveness of early-warning detection SoS with the cooperation efficiency factors of the early-warning aircraft and other land based radars, the evaluation indexes are further designed and the relative evaluation model is further established, especially the evaluation radar chart being also drawn to obtain the evaluation results from a direct sight angle. Finally, some practical computer simulations are launched to prove the validity and feasibility of the research thinking and technologic approaches which are proposed in the paper.

Changes in the influence of the western Pacific subtropical high on Asian summer monsoon rainfall in the late 1990s

NASA Astrophysics Data System (ADS)

Huang, Yanyan; Wang, Bin; Li, Xiaofan; Wang, Huijun

2017-10-01

The Year-to-year variability of the western Pacific subtropical high (WPSH) is primarily controlled by atmosphere-ocean interaction (AOI) between the WPSH and the Indo-Pacific warm pool dipole SST anomalies (AOI mode) and the anomalous SST forcing from the equatorial central Pacific (the CP forcing mode). In this study, we show that the impacts of the WPSH variability on Asian summer monsoon rainfall have changed after the late 1990s. Before the late 1990s (the PRE epoch), the WPSH primarily affects East Asian summer monsoon (EASM) and had little influence on Indian summer monsoon (ISM), whereas after the late 1990s (the POST epoch), the WPSH has strengthened its linkage to the ISM while weakened its relationship with the EASM. This epochal change is associated with a change in the leading circulation mode in the Asia-WP region. During the PRE (POST) epoch the WPSH variation is mainly controlled by the AOI (CP forcing) that mainly affects EASM (ISM). The epochal change of the leading mode may be attributed to the change of the ENSO properties in late 1990s: the CP types of El Nino become a leading ENSO mode in the POST epoch. This work provides a new perspective for understanding decadal changes of the ENSO-monsoon relationship through subtropical dynamics.

Forty to fifty percent decreases in acidic deposition through the 1980s and 1990s led to partial recovery of acidified surface waters in the northeastern United States; however, the limited number of studies that have assessed soil change found increased soil acidification during this period. From existing data, it's not clear whether soils continued to worsen in the 1990s or if recovery had begun. To evaluate possible changes in soils through the 1990s, soils in six red spruce (Picea rubens Sarg.) stands in New York, Vermont, New Hampshire, and Maine, first sampled in 1992 to 1993, were resampled in 2003 to 2004. The Oa-horizon pH increased (P 42−, which decreased the mobility of Al throughout the upper soil profile. Results indicate a nascent recovery driven largely by vegetation processes.

The aim of this study was to determine the scope and contents of peer-reviewed scientific publications that bring the results of the Health System Research (HSR) in the Republic of Croatia during the 1990-2010 period. The basic guidelines are in line with the research project, Health Services Research into European Policy and Practice (HSREPP). This project is being implemented with the aim of identifying, evaluating and improving the contribution of Health System Research to the development of Health Policy in Europe. This study included scientific publications indexed in the PubMed database and master theses and doctoral dissertations published at Schools of Medicine in Zagreb, Osijek, Rijeka and Split during the 1990-2010 period. In accordance with the project methodology, scientific publications indexed in PubMed (http://www.ncbi.nlm.nih.gov/pubmed) were searched for by the key words "Croatia AND (Health Care System OR Health System OR Healthcare System)". Then, the database of scientific publications indexed in PubMed was narrowed by key words divided into 4 groups according to HSREPP instructions. The search for master theses and doctoral dissertations was carried out by direct inspection of the completed works in the library of Andrija Stampar School of Public Health, School of Medicine, University of Zagreb. Access to master theses and doctoral dissertations at the other three medical schools was done by the Internet. We analyzed the collected summaries of all publications, master theses and doctoral dissertations and excluded all those that did not correspond to our research. Using this method, we found a total of 536 publications indexed in PubMed-in, 70 master theses and 22 doctoral dissertations meeting the study criteria. For further analysis, we separately considered master theses and doctoral dissertations on the one side, and scientific publications indexed in PubMed on the other side.

During the late 1990`s and beyond, oil prices will be stagnant while costs increase, competition for markets and capital will be fierce, funds available for exploration and development will be limited, and environmental extremists will keep prospective areas off-limits. Higher taxes will limit growth in oil and gas demand and reapportion energy market shares. And a campaign to brand oil use as an ``addiction`` that must be cured will gather steam. But opportunities abound, too, even in the US High-quality properties are available throughout the US, independents can find and develop reserves cheaper than the majors, and new tools aremore » available to reduce risks both in the field and in the market. Gas prices are firming and natural gas is often labeled the ``fuel of the future.`` To succeed in the petroleum industry of the 1990`s, all companies must accept change, be creative, and take initiative. To prosper, oil and gas producers and refiners and those who supply and serve the industry must face the new realities of the market. They cannot mark time until the return of 4,000 active rigs and $40/bbl oil. those days are never coming back. Never.« less

Getting a piece of the pie? The economic boom of the 1990s and declining teen birth rates in the United States.

PubMed

Colen, Cynthia G; Geronimus, Arline T; Phipps, Maureen G

2006-09-01

In the United States, the 1990s was a decade of dramatic economic growth as well as a period characterized by substantial declines in teenage childbearing. This study examines whether falling teen fertility rates during the 1990s were responsive to expanding employment opportunities and whether the implementation of the Personal Responsibility and Work Opportunities Act (PRWORA), increasing rates of incarceration, or restrictive abortion policies may have affected this association. Fixed-effects Poisson regression models were estimated to assess the relationship between age-specific birth rates and state-specific unemployment rates from 1990 to 1999 for Black and White females aged 10-29. Falling unemployment rates in the 1990s were associated with decreased childbearing among African-American women aged 15-24, but were largely unrelated to declines in fertility for Whites. For 18-19 year-old African-Americans, the group for whom teen childbearing is most normative, our model accounted for 85% of the decrease in rates of first births. Young Black women, especially older teens, may have adjusted their reproductive behavior to take advantage of expanded labor market opportunities.

A significant number of spacecraft are planning to use halo orbits and lunar-swingby trajectories in the next decade. Four spacecraft will be placed into halo orbits around the earth's sunward libration point, while two others will be stationed near the sun-earth L2 libration point in the distant geomagnetic tail. Six spacecraft, including two of the aforementioned halo orbiters, will make use of lunar-swingby maneuvers to fulfill their mission objectives. Thus, a total of ten spacecraft, five from the Soviet Union, two from Japan, two from the United States, and one from the European Space Agency, will employ halo orbits and/or lunar-swingby trajectories in the 1990's. Pertinent facts are presented for each of these missions.

According to the "fundamental cause" theory, emerging knowledge on health-enhancing behaviours and technologies results in health disparities. This study aims to assess (trends in) educational inequalities in site-specific cancer mortality in Belgian men in the 1990s and the 2000s using this framework. Data were derived from record linkage between the Belgian censuses of 1991 and 2001 and register data on mortality. The study population comprised all Belgian men aged 50-79 years during follow-up. Both absolute and relative inequality measures have been calculated. Despite an overall downward trend in cancer mortality, educational differences are observed for the majority of cancer sites in the 2000s. Generally, inequalities are largest for mortality from preventable cancers. Trends over time in inequalities are rather stable compared with the 1990s. Educational differences in site-specific cancer mortality persist in the 2000s in Belgium, mainly for cancers related to behavioural change and medical interventions. Policy efforts focussing on behavioural change and healthcare utilization remain crucial in order to tackle these increasing inequalities.

2013-01-01

Poly(2-oxazoline)s (POx) are currently discussed as an upcoming platform for biomaterials design and especially for polymer therapeutics. POx meets several requirements needed for the development of next-generation polymer therapeutics such as biocompatibility, high modulation of solubility, variation of size, architecture as well as chemical functionality. Although in the early 1990s first and promising POx-based systems were presented but the field lay dormant for almost two decades. Only very recently, POx based polymer therapeutics came back into the focus of very intensive research. In this review, we give an overview on the chemistry and physicochemical properties of POx and summarize the research of POx-protein conjugates, POx-drug conjugates, POx-based polyplexes and POx micelles for drug delivery.

We estimate changes in forest cover (deforestation and forest regrowth) in the tropics for the two last decades (1990–2000 and 2000–2010) based on a sample of 4000 units of 10 ×10 km size. Forest cover is interpreted from satellite imagery at 30 × 30 m resolution. Forest cover changes are then combined with pan-tropical biomass maps to estimate carbon losses. We show that there was a gross loss of tropical forests of 8.0 million ha yr−1 in the 1990s and 7.6 million ha yr−1 in the 2000s (0.49% annual rate), with no statistically significant difference. Humid forests account for 64% of the total forest cover in 2010 and 54% of the net forest loss during second study decade. Losses of forest cover and Other Wooded Land (OWL) cover result in estimates of carbon losses which are similar for 1990s and 2000s at 887 MtC yr−1 (range: 646–1238) and 880 MtC yr−1 (range: 602–1237) respectively, with humid regions contributing two-thirds. The estimates of forest area changes have small statistical standard errors due to large sample size. We also reduce uncertainties of previous estimates of carbon losses and removals. Our estimates of forest area change are significantly lower as compared to national survey data. We reconcile recent low estimates of carbon emissions from tropical deforestation for early 2000s and show that carbon loss rates did not change between the two last decades. Carbon losses from deforestation represent circa 10% of Carbon emissions from fossil fuel combustion and cement production during the last decade (2000–2010). Our estimates of annual removals of carbon from forest regrowth at 115 MtC yr−1 (range: 61–168) and 97 MtC yr−1 (53–141) for the 1990s and 2000s respectively are five to fifteen times lower than earlier published estimates.

Trends in maternal and infant health in poor urban neighborhoods: good news from the 1990s, but challenges remain.

PubMed

Howell, Embry M; Pettit, Kathryn L S; Kingsley, G Thomas

2005-01-01

During the 1990s, numerous public policy changes occurred that may have affected the health of mothers and infants in low-income neighborhoods. This article examines trends in key maternal and child health indicators to determine whether disparities between high-poverty neighborhoods and other neighborhoods have declined. Using neighborhood-level vital statistics and U.S. Census data, we categorized "neighborhoods" (Census tracts) as being high poverty (greater than 30% of population below the federal poverty level in 1990) or not. We compared trends in four key indicators--births to teenagers, late prenatal care, low birth-weight; and infant mortality--over the 1990s among high-poverty and other neighborhoods in Cuyahoga County, Ohio; Denver, Colorado; Marion County, Indiana; and Oakland, California. In all four metropolitan areas, trends in high-poverty neighborhoods were more favorable than in other neighborhoods. The most consistently positive trend was the reduction in the rate of teen births. The metropolitan areas with the most intensive programs to improve maternal and child health--Cuyahoga County and Oakland-saw the most consistent improvement across all indicators. Still, great disparities between high-poverty and other neighborhoods remain, and only Oakland shows promise of achieving some of the Healthy People 2010 maternal and child health goals in its high-poverty neighborhoods. While there has been a reduction in maternal and infant health disparities between high-poverty and other neighborhoods, much work remains to eliminate disparities and achieve the 2010 goals. Small area data are useful in isolating the neighborhoods that should be targeted. Experience from the 1990s suggests that a combination of several intensive interventions can be effective at reducing disparities.

Only 8% of ischemic stroke (IS) patients are eligible for rt-PA, and the largest exclusion criterion is delayed time of presentation to the ED. We sought to investigate whether patients are arriving to the ED more quickly in 1999 than in 1993/94 within our large biracial population of 1.3 million. Using ICD-9 codes 430-436, we ascertained all stroke events that presented to a local ED within our population in 7/93-6/94 and again in 1999. Times were recorded as documented in the medical record. There were 1,792 IS patients that presented to an ED in 1993/94 and 1,973 in 1999. The percentage of patients with documented times arriving in under 3 h improved slightly in 1999 (26% vs. 23% in 93/94, P = 0.03), however, the percentage arriving in under 2 h did not. Blacks significantly improved in arrivals under 3 h: 26% in 1999 compared to 17% in 1993/94 (P = 0.01), while whites did not (26% vs. 25%, P = 0.29). In 1999, only 9% of patients arrived from 3-8 h after symptom onset, the large majority of times were either estimated, unknown, or >8 h. We found only marginal improvement in arrival times during the 1990s. In our population, blacks improved in early arrival after symptom onset, while whites did not. Very few patients arrive 3-8 h after onset; therefore expansion of the acute treatment time window to 8 h is unlikely to dramatically affect acute treatment of ischemic stroke.

The number of scientific papers is a conventional metric for the measurement of a country's research performance in a particular area. To evaluate the trend in Iranian publications of dental research results in peer-reviewed international scientific journals over the period 1999-2009, using national and international databases, and to compare the results with other countries. The search process was performed by two independent persons in PubMed and Iranian Medline (IranMedex). Data extraction included the year of publication, total number of dental papers in each year, total number of Iranian dental papers in each year and number of papers with a high level of evidence; these were compared with those in other Asian countries. The total number of dental articles indexed in PubMed during the studied period was 207,689, with 671 being written by researchers who stated their affiliation as Iran. Although the proportion of Iranian dental articles to all published dental articles was 0.01% in 1990, this increased to 1.4% in 2009. Of all clinical trials indexed in PubMed from 1990 to 2009, only 0.62% had an author from Iran. The collaboration rate of authors ranged between 1 and 10. Turkey and Iran had a larger number of dental research publications compared with other Asian countries assessed in this study. During the last two decades, there has been a considerable increase in the number of dental papers by Iranian researchers indexed in the PubMed database. © 2012 FDI World Dental Federation.

Schistosomiasis is a parasitic disease that menaces human health. In terms of impact, this disease is second only to malaria as the most devastating parasitic disease. Oncomelania hupensis (snail) is the unique intermediate host of schistosoma, so monitoring and controlling of the number of snail is key to reduce the risk of schistosomiasis transmission. Remote sensing technology can real-timely access the large-scale environmental factors related to snail breeding and reproduction, and can also provide the efficient information to determine the location, area, and spread tendency of snail. Based on the T-S (Takagi-Sugeno) fuzzy information theory, a quantitative remote sensing monitoring model of snail has been developed in previous wok. In a case study, this paper will take Xinmin beach, Gaoyou Lake as new research area, carry out 20 years (1990 - 2010) dynamic monitoring, to further validate the effectiveness of the T-S Fuzzy RS snail monitoring model.

Concern about future anthropogenic warming has lead to demands for information on what might happen to fish and fisheries under various climate-change scenarios. One suggestion has been to use past events as a proxy for what will happen in the future. In this paper a comparison between the responses of Atlantic cod ( Gadus morhua) to two major warm periods in the North Atlantic during the 20th century is carried out to determine how reliable the past might be as a predictor of the future. The first warm period began during the 1920s, remained relatively warm through the 1960s, and was limited primarily to the northern regions (>60°N). The second warm period, which again covered the northern regions but also extended farther south (30°N), began in the 1990s and has continued into the present century. During the earlier warm period, the most northern of the cod stocks (West Greenland, Icelandic, and Northeast Arctic cod in the Barents Sea) increased in abundance, individual growth was high, recruitment was strong, and their distribution spread northward. Available plankton data suggest that these cod responses were driven by bottom-up processes. Fishing pressure increased during this period of high cod abundance and the northern cod stocks began to decline, as early as the 1950s in the Barents Sea but during the 1960s elsewhere. Individual growth declined as temperatures cooled and the cod distributions retracted southward. During the warming in the 1990s, the spawning stock biomass of cod in the Barents Sea again increased, recruitment rose, and the stock spread northward, but the individual growth did not improve significantly. Cod off West Greenland also have shown signs of improving recruitment and increasing biomass, albeit they are still very low in comparison to the earlier warming period. The abundance of Icelandic cod, on the other hand, has remained low through the recent warm period and spawning stock biomass and total biomass are at levels near the

U.S. Radioecology Research Programs of the Atomic Energy Commission in the 1950s

Reichle, D.E.

2004-01-12

This report contains two companion papers about radiological and environmental research that developed out of efforts of the Atomic Energy Commission in the late 1940s and the 1950s. Both papers were written for the Joint U.S.-Russian International Symposium entitled ''History of Atomic Energy Projects in the 1950s--Sociopolitical, Environmental, and Engineering Lessons Learned,'' which was hosted by the International Institute for Applied Systems Analysis in Laxemberg, Austria, in October 1999. Because the proceedings of this symposium were not published, these valuable historic reviews and their references are being documented as a single ORNL report. The first paper, ''U.S. Radioecology Research Programsmore » Initiated in the 1950s,'' written by David Reichle and Stanley Auerbach, deals with the formation of the early radioecological research programs at the U.S. Atomic Energy Commission's nuclear production facilities at the Clinton Engineering Works in Oak Ridge, Tennessee; at the Hanford Plant in Richland, Washington; and at the Savannah River Plant in Georgia. These early radioecology programs were outgrowths of the environmental monitoring programs at each site and eventually developed into the world renowned National Laboratory environmental program sponsored by the Office of Biological and Environmental Research of the U.S. Department of Energy. The original version of the first paper was presented by David Reichle at the symposium. The second paper, ''U.S. Atomic Energy Commission's Environmental Research Programs Established in the 1950s,'' summarizes all the environmental research programs supported by the U.S. Atomic Energy Commission in the 1950s and discusses their present-day legacies. This paper is a modified, expanded version of a paper that was published in September 1997 in a volume commemorating the 50th anniversary symposium of the U.S. Department of Energy's Office of Biological and Environmental Research (DOE/BER).

Background Finding a peripheral tissue biopsy site to diagnose early Parkinson’s disease would be of value for clinical care, biomarker validation, and as research enrollment criteria. While autopsy and advanced Parkinson’s disease studies suggest submandibular gland is an important biopsy site, there are no studies in early Parkinson’s disease. Objectives Determine whether needle biopsy of the submandibular gland reveals Lewy type α-synucleinopathy in early Parkinson’s disease. Methods Twenty-five early Parkinson’s disease (duration < 5 years) and 10 controls underwent transcutaneous needle core biopsies of the submandibular gland. Tissue was stained for phosphorylated α-synuclein, reviewed blind to clinical diagnosis, and only nerve element staining was considered positive. Results Mean (Standard Deviation) age 69.5 (8.3) for Parkinson’s disease group, 64.8 (8.0) years for controls, and disease duration 2.6 (1.1) years. Six Parkinson’s disease and one control subject had inadequate glandular tissue. Positive staining was found in 14/19 (74%) Parkinson’s disease and 2/9 (22%) control subjects. Parkinson’s disease positive and negative cases did not differ clinically. Adverse events (mainly swelling and bruising) were common (77% of cases), but were minor and transient. Conclusions Submandibular gland needle biopsies identified phosphorylated α-synuclein staining in 74% of early Parkinson’s disease subjects. False positives may be true false positives or may represent prodromal Parkinson’s disease. If confirmed in larger studies with eventual autopsy confirmation, the potential value of submandibular gland biopsies for early Parkinson’s disease may be to aid in clinical trial inclusion/exclusion and eventually serve as a gold standard for biomarker studies short of autopsy confirmation.

Distinct zooplankton regime shift patterns across ecoregions of the U.S. Northeast continental shelf Large Marine Ecosystem

NASA Astrophysics Data System (ADS)

Morse, R. E.; Friedland, K. D.; Tommasi, D.; Stock, C.; Nye, J.

2017-01-01

We investigated regime shifts in seasonal zooplankton communities of the Northeast continental shelf Large Marine Ecosystem (NES) and its subcomponent ecoregions over a multi-decadal period (1977-2013). Our cross ecoregion analysis shows that regime shifts in different ecoregions often exhibited very distinct characteristics, emphasizing more granular fluctuations in NES plankton communities relative to previous work. Shifts early in the time series generally reflected an increase in abundance levels. The response of zooplankton abundance within fall communities was more similar among ecoregions than for spring communities. The Gulf of Maine exhibited highly distinct patterns from other ecoregions, with regime shifts identified in the early 1980s, early 2000s, and mid-2000s for spring communities. Regime shifts were identified in the early to mid-1990s for the NES, Georges Bank, and the Mid-Atlantic Bight ecoregions, while the fall communities experienced shifts in the early 1990s and late 1980s for the NES and Georges Bank, but in the late 1990s in the Mid-Atlantic Bight. A constrained correspondence analysis of zooplankton community against local and basin-scale climatological indices suggests that water temperature, stratification, and the Atlantic multidecadal oscillation (AMO) were the predominant factors in driving the zooplankton community composition.

We quantified the shallowing of the seafloor in five of six bays examined in the Chignik region of the Alaska Peninsula, confirming National Ocean Service observations that 1990s hydrographic surveys were shallower than previous surveys from the 1920s. Castle Bay, Chignik Lagoon, Hook Bay, Kujulik Bay and Mud Bay lost volume as calculated from Mean Lower Low Water (Chart Datum) to the deepest depths and four of these sites lost volume from Mean High Water to the deepest depths. Calculations relative to each datum were made because tidal datum records exhibited an increase in tidal range in this region from the 1920s to the 1990s. Our analysis showed that Mud Bay is quickly disappearing while Chignik Lagoon is being reduced to narrow channels. Anchorage Bay was the only site that increased in depth over time, perhaps due to erosion. Volcanoes dominate the landscape of the Chignik area. They have blanketed the region in deep ash deposits before the time frame of this study, and some have had smaller ash-producing eruptions during the time frame of this study. Remobilization of land-deposited ash and redeposition in marine areas - in some locations facilitated by extensive eelgrass (Zostera marina) beds (covering 54% of Chignik Lagoon and 68% of Mud Bay in 2010) - is the most likely cause of shallowing in the marine environment. Loss of shallow water marine habitat may alter future abundance and distribution of several fish, invertebrate and avian species.

One of the most important achievements in 1998-1999 of Phare Topic Link on Land Cover has been the development and practical application of a methodological approach to landscape change identification and analysis in the territories of four Phare countries (the Czech Republic, Hungary, Romania, and the Slovak Republic). The changes were identified on a national level from Landsat TM and MSS satellite images by application of the CORINE Land Cover databases for two time horizons (the late 1970s and early 1990s) at the second hierarchic level. Based on identified causality, the landscape changes were grouped into 7 types: intensification of agriculture, extensification of agriculture, urbanisation-industrialisation, enlargement (exhaustion) of natural resources, afforestation, deforestation and other anthropogenic causes. The results of the groupings are presented in the form of contingency tables and maps showing the spatial distribution of the changes. From the point of view of total extent, forest landscape changed the most in the Czech Republic. This change represents a reduction of forest by 167,702 ha and an enlargement of transitional woodland-scrub by about 26,339 ha. In Hungary the most pronounced changes were decrease of forests by 66,622 ha and decrease of arable land, orchards and vineyards by 21,529 ha. The most remarkable changes identified in Romania were decrease of arable land, forests and wetlands by 366,817 ha, 285,887 ha, and 59,967 ha, respectively, as well as enlargement of areas of complex cultivation pattern by almost 347,220 ha. The most pronounced changes in Slovakia were represented by diminution of forest by 94,935 ha and that of heterogeneous agricultural areas by 18,451 ha; enlargement of transitional woodland-scrub areas and urbanised area were about 13,107 ha and 14,990 ha, respectively.

Anhydrite in the 1989 1990 lavas and xenoliths from Redoubt Volcano, Alaska

The eruption of Redoubt Volcano in Alaska produced a moderate sulfur emission (estimated at 1 × 10 tons SO 2), but relatively small volume of lava (0.11 km ) with pre-eruption estimates of 840-950 °C and fO 21.5 to 2.0 log units above NNO (Swanson, S.E., Nye, C.J., Miller, T.P., Avery, V.F., 1994. Magma mixing in the 1989-1990 eruption of Redoubt Volcano: Part II. Evidence from mineral and glass chemistry. Journal of Volcanology and Geothermal Research 62, 453-468). Petrologic estimates of sulfur production (Sigurdsson, H., Devine, J.D.,Davis, A.N., 1985. The petrologic estimation of volcanic degassing. Jokull 35, 1-8) from this eruption (Gerlach, T., Westrich, H.R., Casadevall, T.J., Finnegan, D.L., 1994. Vapor Saturation and accumulation in magmas of the 1989-1990 eruption of Redoubt Volcano, Alaska. Journal of Volcanology and Geothermal Research 62, 317-337) are considerably less than the measured sulfur emission, leading workers to propose the existence of a pre-eruption vapor phase to explain the "excess" sulfur. Initial examination of the 1989-1990 Redoubt eruptive products reported anhydrite (Nye, C.J., Swanson, S.E., Avery, V.F., Miller, T.P., 1994. Geochemistry of the 1989-1990 eruption of Redoubt Volcano: Part I, whole-rock, major- and trace-element chemistry. Journal of Volcanology and Geothermal Research 62, 429-452.) in interstitial glass from some cognate gabbroic xenoliths, but anhydrite was not noted in any of the andesites. A Boeing 747 encountered the ash plume from the initial eruptive phase on December 15, 1989 and provided ash samples that reportedly contained gypsum (Bayhurst, G.K., Wohletz, K.H., Mason, A.S., 1994. A method for characterizing volcanic ash from the December 15, 1989, eruption of Redoubt Volcano, Alaska. U.S. Geological Survey Bulletin 2047, 13-17). However, the identification was based on EDS analyses on a SEM and the mineral could have been anhydrite. Reexamination of the 1989-1990 Redoubt lavas and xenoliths revealed the

This article sets up the initial discussion of the evolution of biopharmaceutical innovation in China through the perspective of sectoral innovation system (SIS). Two data sources including archival documentary data and field interviews were used in this study. Archival documentary data was collected from China Food and Drug Administration (CFDA) and Chinese National Knowledge Infrastructure (CNKI). In addition, industrial practitioners and leading researchers in academia were interviewed. Biopharmaceutical in China was established through international knowledge transfer. The firms played more active role in commercializing biopharmaceutical in China though universities and research institutes were starting to interact with local firms and make contribution to biopharmaceutical industrialization. The transition of the Chinese government's policies continuously shapes the evolution of biopharmaceutical sector. Policies have been dramatic changes before and after 1980s to encourage developing biopharmaceutical as a competitive industry for China. A SIS for biopharmaceutical has been shaped in China. However, currently biopharmaceutical is still a small sector in China, and for the further growth of the industry more synthetic policies should be implemented. Not only the policy supports towards the research and innovation of biopharmaceuticals in the early stage of development should be attended, but also commercialization of biopharmaceutical products in the later stage of sales. © 2015 by Kerman University of Medical Sciences.

To assess the range of doses in paediatric CT scans conducted in the 1990s in Norway as input to an international epidemiology study: the EPI-CT study, http://epi-ct.iarc.fr/ . National Cancer Institute dosimetry system for Computed Tomography (NCICT) program based on pre-calculated organ dose conversion coefficients was used to convert CT Dose Index to organ doses in paediatric CT in the 1990s. Protocols reported from local hospitals in a previous Norwegian CT survey were used as input, presuming these were used without optimization for paediatric patients. Large variations in doses between different scanner models and local scan parameter settings are demonstrated. Small children will receive a factor of 2-3 times higher doses compared with adults if the protocols are not optimized for them. For common CT examinations, the doses to the active bone marrow, breast tissue and brain may have exceeded 30 mGy, 60 mGy and 100 mGy respectively, for the youngest children in the 1990s. The doses children received from non-optimised CT examinations during the 1990s are of such magnitude that they may provide statistically significant effects in the EPI-CT study, but probably do not reflect current practice. • Some organ doses from paediatric CT in the 1990s may have exceeded 100 mGy. • Small children may have received doses 2-3 times higher compared with adults. • Different scanner models varied by a factor of 2-3 in dose to patients. • Different local scan parameter settings gave dose variations of a factor 2-3. • Modern CTs and age-adjusted protocols will give much lower paediatric doses.

The interannual variability and trend of above-ground photosynthetic activity of Arctic tundra vegetation in the 1990s is examined for the north slope region of Alaska, based on the seasonally integrated normalized difference vegetation index (SINDVI) derived from local area coverage (LAC) National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) data. Smaller SINDVI values occurred during the three years (1992-1994) following the volcanic eruption of Mt Pinatubo. Even after implementing corrections for this stratospheric aerosol effect and adjusting for changes in radiometric calibration coefficients, an apparent increasing trend of SINDVI in the 1990s is evident for the entire north slope. The most pronounced increase was observed for the foothills physiographical province.

Health policy and systems research collaboration pathways: lessons from a network science analysis.

English, Krista M; Pourbohloul, Babak

The 2004 Mexico Declaration, and subsequent World Health Assembly resolutions, proposed a concerted support for the global development of health policy and systems research (HPSR). This included coordination across partners and advocates for the field of HPSR to monitor the development of the field, while promoting decision-making power and implementing responsibilities in low- and middle-income countries (LMICs). We used a network science approach to examine the structural properties of the HPSR co-authorship network across country economic groups in the PubMed citation database from 1990 to 2015. This analysis summarises the evolution of the publication, co-authorship and citation networks within HPSR. This method allows identification of several features otherwise not apparent. The co-authorship network has evolved steadily from 1990 to 2015 in terms of number of publications, but more importantly, in terms of co-authorship network connectedness. Our analysis suggests that, despite growth in the contribution from low-income countries to HPSR literature, co-authorship remains highly localised. Lower middle-income countries have made progress toward global connectivity through diversified collaboration with various institutions and regions. Global connectivity of the upper middle-income countries (UpperMICs) are almost on par with high-income countries (HICs), indicating the transition of this group of countries toward becoming major contributors to the field. Network analysis allows examination of the connectedness among the HSPR community. Initially (early 1990s), research groups operated almost exclusively independently and, despite the topic being specifically on health policy in LMICs, HICs provided lead authorship. Since the early 1990s, the network has evolved significantly. In the full set analysis (1990-2015), for the first time in HPSR history, more than half of the authors are connected and lead authorship from UpperMICs is on par with that of HICs

There are many challenges to conducting inter- or multi-disciplinary research because basic research, applied research, management processes, disciplines, and even sub-disciplines have been "siloed" for so long that many research and management professionals find it difficult to communicate common interests and research needs. It is clear that the next generation of researchers must overcome these disciplinary biases and engage in more open dialogue with other disciplines and the management community in order to be better positioned to collaborate, speak a common language, and understand each other's needs. The U.S. Department of the Interior's South Central Climate Science Center recently conducted a professional development workshop for 28 early-career researchers involved in climate-related research across the South-Central U.S. The participants consisted of graduate students, postdocs, and junior faculty representing 17 different natural and social science disciplines and seven Universities/Institutions. The workshop provided the participants with guidance and instruction on how to overcome the identified challenges in conducting "actionable" research and how to better navigate multi-institutional and multi- or inter-disciplinary research. The workshop was comprised of: (1) a series of instructional presentations organized into themed sessions; (2) two keynote addresses to provide a broader perspective; (3) a real-world case study activity; (4) individual and group projects/presentations; and (5) field trips. In addition, we purposely created informal opportunities for participants to network, which met the goal of facilitating interdisciplinary interactions. An overview of the workshop experience will be provided, including a focus on those aspects leading to its ultimate success and recommendations for how to develop and implement a similar early-career workshop for your own purposes.

To check the influence of boundary input data on a modeling result, we had a numerical investigation of river discharge by using runoff data derived by a regional climate model with a 4.5-km resolution as input data to a hydrological model. A hindcast experiment, which to reproduce the current climate was carried out for the two decades, 1980s and 1990s. We used the Advanced Research WRF (ARW) (ver. 3.2.1) with a two-way nesting technique and the WRF single-moment 6-class microphysics scheme. Noah-LSM is adopted to simulate the land surface process. The NCEP/NCAR and ERA-Interim 6-hourly reanalysis datasets were used as the lateral boundary condition for the runs, respectively. The output variables used for river discharge simulation from the WRF model were underground runoff and surface runoff. Four rivers (Mogami, Agano, Jinzu and Tone) were selected in this study. The results showed that the characteristic of river discharge in seasonal variation could be represented and there were overestimated compared with measured one.

Tobacco lobby political influence on US state legislatures in the 1990s

PubMed Central

Givel, M.; Glantz, S.

2001-01-01

BACKGROUND—Throughout the 1990s the tobacco lobby was a potent political force in US state legislatures advancing its pro-tobacco agenda.
OBJECTIVE—To describe the market and political motivations of the tobacco lobby and the strategies they use to achieve these goals in US state legislatures.
DESIGN—This study is a content analysis and summary overview of recently released historical tobacco industry documents; tobacco related government documents; and recent state tobacco control policy reports.
RESULTS—In the 1990s, the tobacco lobby engaged in a comprehensive and aggressive political effort in state legislatures to sell tobacco with the least hindrance using lobbying, the media, public relations, front groups, industry allies, and contributions to legislators. These efforts included campaigns to neutralise clean indoor air legislation, minimise tax increases, and preserve the industry's freedom to advertise and sell tobacco. The tobacco lobby succeeded in increasing the number of states that enacted state pre-emption of stricter local tobacco control laws and prevented the passage of many state tobacco control policies. Public health advocates were able to prevent pre-emption and other pro-tobacco policies from being enacted in several states.
CONCLUSIONS—The tobacco lobby is a powerful presence in state legislatures. Because of the poor public image of the tobacco lobby, it seeks to wield this power quietly and behind the scenes. State and local health advocates, who often have high public credibility, can use this fact against the tobacco lobby by focusing public attention on the tobacco lobby's political influence and policy goals and expose links between the tobacco lobby and its legislative supporters.

The prinicipal findings of the second forest survey of Puerto Rico (1990) and changes that have occurred since the survey was established in 1980 are presented. The forest inventory estimates describe the timber resource found within the potential commercial region designated in the first survey. The timber resource addressed consists primarily of regrown areas on abandoned pastures and cropland, including coffee production areas. The status and trends of the timber resource are presented for the two Life Zones occurring in the commercial region, as well as for various forest classes, which are based on stand history and origin. Topics dicussedmore » include forest area, timberland area, basal area, species composition, timber volume, growing-stock volume, and sawtimber volume. results of the 1990 survey are promising, showing inceases in numbers of trees across all diamater classes and substantial increases in volume. These trends offer evidence that Puerto Rico`s forests are continuing to recover following a dramatic decline of the late 19th and early 20th centuries.« less

Progress on Updating the 1961-1990 National Solar Radiation Database

Renne, D.; Wilcox, S.; Marion, B.; George, R.; Myers, D.

2003-01-01

The 1961-1990 National Solar Radiation Data Base (NSRDB) provides a 30-year climate summary and solar characterization of 239 locations throughout the United States. Over the past several years, the National Renewable Energy Laboratory (NREL) has received numerous inquiries from a range of constituents as to whether an update of the database to include the 1990s will be developed. However, there are formidable challenges to creating an update of the serially complete station-specific database for the 1971-2000 period. During the 1990s, the National Weather Service changed its observational procedures from a human-based to an automated system, resulting in the loss of important input variables to the model used to complete the 1961-1990 NSRDB. As a result, alternative techniques are required for an update that covers the 1990s. This paper examines several alternative approaches for creating this update and describes preliminary NREL plans for implementing the update.

Accountable care organizations may have difficulty avoiding the failures of integrated delivery networks of the 1990s.

PubMed

Burns, Lawton R; Pauly, Mark V

2012-11-01

Accountable care organizations are intended to improve the quality and lower the cost of health care through several mechanisms, such as disease management programs, care coordination, and aligning financial incentives for hospitals and physicians. Providers employed several of these mechanisms in forming the integrated delivery networks of the 1990s. The networks failed, however, because of heavy financial losses stemming from hospitals' purchase of physician practices and their inability to align incentives, garner capitated contracts, and develop the infrastructure to manage risk. Although the current mechanisms underlying accountable care organizations continue to evolve, whether and how they will have an impact on quality and costs remains open to question. Care coordination and information technology are proving more complicated and expensive to implement than anticipated, providers may lack the ability to implement these mechanisms, and primary care providers are in short supply. As in the 1990s, success depends on targeting specific populations, such as people with multiple chronic conditions who need and may benefit from coordinated care.

Early-life Origins of Lifecycle Well-being: Research and Policy Implications

PubMed Central

Currie, Janet; Rossin-Slater, Maya

2016-01-01

Mounting evidence across different disciplines suggests that early-life conditions can have consequences on individual outcomes throughout the lifecycle. Relative to other developed countries, the United States fares poorly on standard indicators of early-life health, and this disadvantage may have profound consequences not only for population well-being, but also for economic growth and competitiveness in a global economy. In this paper, we first discuss the research on the strength of the link between early-life health and adult outcomes, and then provide an evidence-based review of the effectiveness of existing U.S. policies targeting the early-life environment. We conclude that there is a robust and economically meaningful relationship between early-life conditions and well-being throughout the lifecycle, as measured by adult health, educational attainment, labor market attachment, and other indicators of socio-economic status. However, there is some variation in the degree to which current policies in the U.S. are effective in improving early-life conditions. Among existing programs, some of the most effective are the Special Supplemental Program for Women, Infants, and Children (WIC), home visiting with nurse practitioners, and high-quality, center-based early childhood care and education. In contrast, the evidence on other policies such as prenatal care and family leave is more mixed and limited. PMID:25558491

In 1974-1976, baseline studies were carried out on the flora and macroinvertebrate fauna of the R. Kennet at two sites downstream of Marlborough (Savernake Upper and Lower) and at one site upstream of Hungerford (Littlecote). Simplified maps of each site, showing the cover of macrophytes, were obtained monthly between April 1974 and April/June 1976, and replicated quantitative samples of the macroinvertebrates were collected on the dominant macrophyte and on gravel in June 1974, and also in June and December 1975. As a consequence of two major droughts and increasing concern over water quality in the Upper Kennet in the 1990s, the studies recommenced in the summer of 1997 using the same sites and methodologies. Maps and macroinvertebrate samples were obtained in early July and December 1997 and in June of both 1998 and 1999. At the Savernake sites, mapping in summer 1997 confirmed what had been apparent for some years. That is, macrophyte cover (both Ranunculus and Schoenoplectus) was much lower than in the 1970s. In contrast, the site downstream at Littlecote retained a relatively high cover of Ranunculus, despite the drought. In late autumn 1997, phosphate stripping commenced at Marlborough Sewage Treatment Works, the drought ended and in addition, the spring of 1998 was unusually wet. Ranunculus recolonised both Savernake sites with remarkable speed by summer 1998 and retained this dominant position in 1999. Quantitative samples of macroinvertebrates collected on gravel and the dominant macrophyte at each of the three study sites indicated that there was no evidence of major loss of family richness between the 1970s and 1990s as a result of the low flows or enrichment. However, at Savernake (but not Littlecote) in summer 1997, the macroinvertebrate assemblage was affected by low flows and/or enrichment. This took the form of changes in the abundance of some families, with lentic forms being favoured in relation to some lotic families. Following the end of the

2011-01-01

Since the publication of the first paper on “cytochrome P450” in 1962, the biochemical research on this novel hemoprotein expanded rapidly in the 1960s and the 1970s as its principal roles in various important metabolic processes including steroid hormone biosynthesis in the steroidogenic organs and drug metabolism in the liver were elucidated. Establishment of the purification procedures of microsomal and mitochondrial P450s in the middle of the 1970s together with the introduction of molecular biological techniques accelerated the remarkable expansion of the research on P450 in the following years. This review paper summarizes the important developments in the research on P450 in the early years, for about two decades from the beginning, together with my personal recollections. PMID:22156409

Whyte, N; Stone, S

2000-06-01

This paper documents the work of one provincial nursing association, the Registered Nurses Association of British Columbia (RNABC), to promote primary health care (PHC) as the foundation of the health-care system. In 1990 the RNABC embarked on a comprehensive policy program to influence change from a nursing perspective. A wide array of strategies was used over a 10-year period to help make PHC a reality in British Columbia's health-care system. Successful strategies used during this period included: writing and distributing policy papers, conducting and evaluating demonstration projects, and developing partnerships with other groups. Some of the projects and their outcomes are highlighted, followed by a critical reflection on lessons learned through the various initiatives. Although remarkable achievements were made from the RNABC's policy work during the 1990s, the advancement of PHC requires further collaborative efforts using multiple strategies.

Isolation and structure elucidation of most of the major cannabinoid constituents--including Δ(9)-tetrahydrocannabinol (Δ(9)-THC), which is the principal psychoactive molecule in Cannabis sativa--was achieved in the 1960s and 1970s. It was followed by the identification of two cannabinoid receptors in the 1980s and the early 1990s and by the identification of the endocannabinoids shortly thereafter. There have since been considerable advances in our understanding of the endocannabinoid system and its function in the brain, which reveal potential therapeutic targets for a wide range of brain disorders.

view across all technical fields, as related to The Geysers steam-dominated geothermal system. The Geysers has seen many fundamental changes between 1990-2010 and yet the geothermal resource seems still to be robust to the extent that, long after its anticipated life span, we are seeing new geothermal projects being developed on the north and west peripheries of the field. It is hoped that this report provides a focused data source particularly for those just starting their geothermal careers, as well as those who have been involved in the interesting and challenging field of geothermal energy for many years. Despite many hurdles The Geysers has continued to generate electrical power for 50 years and its sustainability has exceeded many early researchers expectations. It also seems probable that, with the new projects described above, generation will continue for many years to come. The success of The Geysers is due to the technical skills and the financial acumen of many people, not only over the period covered by this report (1990-2010), but since the first kilowatt of power was generated in 1960. This Special Report celebrates those 50 years of geothermal development at The Geysers and attempts to document the activities that have brought success to the project so that a permanent record can be maintained. It is strongly hoped and believed that a publication similar to this one will be necessary in another 20 years to document further activities in the field.« less

Factors associated with trends in infant and child mortality in developing countries during the 1990s.

PubMed Central

Rutstein, S. O.

2000-01-01

The 1990s have seen a remarkable decrease in mortality among infants and children in most developing countries. In some countries, particularly in sub-Saharan Africa, these declines in mortality among children have slowed and are now increasing again. Internationally comparable data derived from survey programmes, such as the Demographic and Health Survey (DHS) programme, are available both to document the changes that have occurred in mortality and to provide insight into some of the factors that may explain these trends in mortality. The factors found in repeated DHS programmes that explain these trends fall into five categories: fertility behaviour; nutritional status, breastfeeding, and infant feeding; the use of health services by mothers and for children; environmental health conditions; and socioeconomic status. Both simple analyses and multivariate analyses of changes in these factors between surveys indicate that all factors affected the mortality trends. However, to explain trends in mortality, the variables themselves had to have changed over time. During the 1990s fertility behaviour, breastfeeding, and infant feeding have changed less than other factors and so would seem to have played a smaller role in mortality trends. This study confirms that trends in mortality during the 1990s were related to more than just a handful of variables. It would, therefore, be a mistake to concentrate policy actions on one or a few of these while forsaking others. Countries with the largest decreases in mortality have had substantial improvements in most of the factors that might be used to explain these changes. In some countries mortality has risen. In part these increases can be explained by the factors included in this study, such as deterioration in seeking medical care for children with fever. Other factors that were not measured, such as the increasing resistance of malaria to drug treatment and the increased prevalence of parental HIV/AIDS, may be contributing

2015-01-01

The objective of this article is to offer an overview of the health reform in Ceará focusing on the decentralisation process in the 1990s. The driving factor behind the Brazilian health reform movement was the necessity to reorganise the national health system and overcome inequalities. For the reformists, decentralisation, and together with it the idea of popular participation, is seen as essential to guarantee the fulfilment of the people’s needs and to incorporate their voice in the decision-making processes of the health system. In the state of Ceará, after the 1986 elections, health reform movement members took control over the management of the state Health Secretariat. This is the main cause of the acceleration of the decentralisation process with the transference of responsibility over the management of health care delivery to municipalities. PMID:25729333

BACKGROUND Increases in thyroid papillary carcinoma incidence rates have largely been attributed to heightened medical surveillance and improved diagnostics. We examined papillary carcinoma incidence in an equal-access healthcare system by demographics, which are related to incidence. METHODS Incidence rates during 1990-2004 among white and black individuals aged 20-49 years in the military and the general U.S. population were compared using data from the Department of Defense’s Automated Central Tumor Registry and the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER-9) program. RESULTS Incidence was significantly higher in the military than in the general population among white women [incidence rate ratio (IRR)=1.42, 95% 95% confidence interval (CI)=1.25-1.61], black women (IRR=2.31, 95% CI=1.70-2.99), and black men (IRR=1.69, 95% CI=1.10-2.50). Among whites, differences between the two populations were confined to rates of localized tumors (women: IRR=1.73, 95% CI=1.47-2.00; men: IRR=1.51, 95% CI=1.30-1.75), which may partially be due to variation in staging classification. Among white women, rates were significantly higher in the military regardless of tumor size, and rates rose significantly over time both for tumors ≤2 cm (military: IRR=1.64, 95% CI=1.18-2.28; general population: IRR=1.55, 95% CI=1.45-1.66) and >2 cm (military: IRR=1.74, 95% CI=1.07-2.81; general population: IRR=1.48, 95% CI=1.27-1.72). Among white men, rates increased significantly only in the general population. Incidence also varied by military service branch. CONCLUSIONS Heightened medical surveillance does not appear to fully explain the differences between the two populations or the temporal increases in either population. IMPACT These findings suggest the importance of future research into thyroid cancer etiology. PMID:21914838

We investigated changes in the distribution of alcohol consumption by education and marital status in Russia during the period of societal transformation after 1990. Such changes would indicate the potential role of alcohol in the rising social inequalities in mortality. We analysed data from three surveys in random population samples conducted in Novosibirsk as part of the WHO MONICA project in 1985/86 (1533 men, 1292 women), 1988/89 (1700 men, no women) and 1994/95 (1526 men, 1510 women), coinciding with the period of societal transformation. Four measures of drinking were examined in relation to education and marital status: prevalence of drinking at least twice a week; the mean intake in the last week; the mean intake per drinking occasion; and the prevalence of binge drinking (>80 g ethanol for men and >60 g for women) at least once a month. Among men, those with university education had the lowest levels of all measures of drinking. Drinking indices increased over time in all educational groups but most sharply in men with high education, thus leading to a smaller education-related difference in the last survey. With respect to marital status, divorced and widowed men tended to drink most, but the pattern was inconsistent, and the difference between divorced and married men also narrowed over time. Among women, alcohol intake increased between the first and last survey. Differences by education and marital status in women were smaller than in men, and binge drinking was inversely related to education. All indices of alcohol consumption in men increased between the mid 1980s and the mid 1990s. The increase in alcohol intake among men was proportionally similar across categories of education and marital status but the absolute differences increased. The contribution of alcohol to the increase in social differentials in mortality in the 1990s was probably modest.

Reports are contained from the NASA Workshop on Solid Earth Science in the 1990s. The techniques and technologies needed to address the program objectives are discussed. The Measurement Technique and Technology Panel identified (1) candidate measurement systems for each of the measurements required for the Solid Earth Science Program that would fall under the NASA purview; (2) the capabilities and limitations of each technique; and (3) the developments necessary for each technique to meet the science panel requirements. In nearly all cases, current technology or a development path with existing technology was identified as capable of meeting the requirements of the science panels. These technologies and development paths are discussed.

The early history of ideas on brief interventions for alcohol

PubMed Central

McCambridge, Jim; Cunningham, John A

2014-01-01

Aims This study explores the early development of brief interventions for alcohol using a history of ideas approach with a particular focus on intervention content. Methods The source publications of the key primary studies published from approximately 1962 to 1992 were examined, followed by a brief review of the earliest reviews in this field. These studies were placed in the context of developments in alcohol research and in public health. Results After early pioneering work on brief interventions, further advances were not made until thinking about alcohol problems and their treatment, most notably on controlled drinking, along with wider changes in public health, created new conditions for progress. There was then a golden era of rapid advance in the late 1980s and early 1990s, when preventing the development of problem drinking became important for public health reasons, in addition to helping already problematic drinkers. Many research challenges identified at that time remain to be met. The content of brief interventions changed over the period of study, although not in ways well informed by research advances, and there were also obvious continuities, with a renewed emphasis on the facilitation of self-change being one important consequence of the development of internet applications. Conclusions Ideas about brief interventions have changed in important ways. Brief interventions have been studied with different populations of drinkers, with aims embracing both individual and population-level perspectives, and without well-specified contents. The brief intervention field is an appropriate target for further historical investigations, which may help thinking about addressing alcohol and other problems. PMID:24354855

In past years, many SHAs formed in local urban markets to better compete for managed care contracts. In response to 1990s forces, these SHAs appear to have adapted product, production, and selling orientations to their markets, aimed at large institutional purchasers of health care. However, health care markets have evolved differently than anticipated. SHAs and their hospitals should now adopt the marketing orientation and focus more on patients and enrollees.

Strange old worlds: socio-critical reports about old-age experiences in West German print media (1970s-1990s).

PubMed

Streubel, Christiane

2011-01-01

This article examines West German images of old age and the elderly in a period when this increasingly became a topical issue. Between the 1970s and the 1990s, the elderly were the subject of socio-critical reports in leading political magazines like Der Spiegel, Die Zeit and Stern. In these specific journalistic formats, the media entered unfamiliar places like old people's homes, the elderly's private apartments or tea dances for senior citizens. By analysing the language used in such media reports, this article shows continuity and change in attitudes towards the elderly, explores the impact of the new old-age model 'the young at heart', and the relevance of gender and generational ascriptions. In doing so, this article uncovers the recent historical context of current social debates about old age.

Federal roles to realize national energy-efficiency opportunities in the 1990s

NASA Astrophysics Data System (ADS)

Hirst, Eric

1989-10-01

Improving energy efficiency throughout the U.S. economy is a vital component of our nation's energy future, with many benefits. Improving efficiency can: save money consumers, increase economic productivity and international competitiveness, reduce oil and gas prices by reducing the demand for foreign oil, enhance national security by lowering oil imports, reduce the adverse environmental consequences of fuel cycles, especially acid rain and global warming, add diversity and flexibility to the nation's portfolio of energy resources, respond to public interest in, and support of, energy efficiency. The primary purpose of this report is to suggest expanded roles for the U.S. Department of Energy (DOE) in improving energy efficiency during the 1990s. In an ideal world, the normal workings of the market place would yield optimal energy-efficiency purchase and operating decisions. Unfortunately, distortions in fuel prices, limited access to capital, misplaced incentives, lack of information, and difficulty in processing information complicate energy-related decision making. Thus, consumers in all sectors of the economy underinvest in energy-efficient systems. These market barriers, coupled with growing concern about environmental quality, justify a larger Federal role.

Picture archiving and communication system developments expected in the 1990s

Drew, Philip G.; Lorah, Lawrence D.; Lydon, Michael J.; Novak, Elliott D.

Among the applications for high-bandwidth systems are medical picture archiving and communication systems (PACS). Viewed in the light of developments anticipated ten years ago when these systems were first discussed, progress has been disappointingly slow. However, with the recognition that teleradiology, digital archives, and computed radiography can be regarded as PAC subsystems, and that systems confined to a single modality can be regarded as mini-PACS, it becomes clear that development of PAC systems has made remarkable progress. Growing from modest size today, the markets for PAC systems and subsystems in the U.S. is likely to exceed $600 million by the end of the decade, a market of the same magnitude as those for CT, MRI, and catheterization lab equipment. This paper discusses the forces that have stimulated growth of PAC systems - among them, the opportunity to provide better service to patients and referring physicians, a chance to expand effective service area, and a possible solution to the ubiquitous problems of lost films - as well as the impediments that have retarded growth - among them, technical limitations, especially of the radiologists' workstations, and cost. A review of these forces allows prediction of likely developments in the 1990s.

Outcomes research training programs should prepare trainees to successfully compete for research funding. We examined how early-career investigators' prior and desired training aligns with recently funded cardiovascular (CV) outcomes research. We (1) reviewed literature to identify 13 core competency areas in CV outcomes research; (2) surveyed early-career investigators to understand their prior and desired training in each competency area; (3) examined recently funded grants commonly pursued by early-career outcomes researchers to ascertain available funding in competency areas; and (4) analyzed alignment between investigator training and funded research in each competency area. We evaluated 185 survey responses from early-career investigators (response rate 28%) and 521 funded grants from 2010 to 2014. Respondents' prior training aligned with funded grants in the areas of clinical epidemiology, observational research, randomized controlled trials, and implementation/dissemination research. Funding in community-engaged research and health informatics was more common than prior training in these areas. Respondents' prior training in biostatistics and systematic review was more common than funded grants focusing on these specific areas. Respondents' desired training aligned similarly with funded grants, with some exceptions; for example, desired training in health economics/cost-effectiveness research was more common than funded grants in these areas. Restricting to CV grants (n=132) and National Heart, Lung, and Blood Institute-funded grants (n=170) produced similar results. Identifying mismatch between funded grants in outcomes research and early-career investigators' prior/desired training may help efforts to harmonize investigator interests, training, and funding. Our findings suggest a need for further consideration of how to best prepare early-career investigators for funding success. Copyright © 2017. Published by Elsevier Inc.

There is limited information on national health expenditures, services, and outcomes in African countries during the 1990s. We intend to make statistical information available for national level comparisons. National level data were collected from numerous international databases, and supplemented by national household surveys and World Bank expenditure reviews. The results were tabulated and analysed in an exploratory fashion to provide benchmarks for groupings of African countries and individual country comparison. There is wide variation in scale and outcome of health care spending between African countries, with poorer countries tending to do worse than wealthier ones. From 1990-96, the median annual per capita government expenditure on health was nearly US$ 6, but averaged US$ 3 in the lowest-income countries, compared to US$ 72 in middle-income countries. Similar trends were found for health services and outcomes. Results from individual countries (particularly Ethiopia, Ghana, Côte d'Ivoire and Gabon) are used to indicate how the data can be used to identify areas of improvement in health system performance. Serious gaps in data, particularly concerning private sector delivery and financing, health service utilization, equity and efficiency measures, hinder more effective health management. Nonetheless, the data are useful for providing benchmarks for performance and for crudely identifying problem areas in health systems for individual countries. PMID:10916913

European Neutrons form Parasitic Research to Global Strategy: Realizing Plans for a Transnational European Spallation Source in the Wake of the Cold War

2016-03-01

Studies of Big Science have early on focused on instrumentation and scientific co-operation in large organizations, later on to take into account symbolic values and specific research styles while more recently also involving the relevance of commercial interests and economic development as well as the assimilation of research traditions. In accordance with these transformed practices, this presentation will analyze how an organization with the purpose of realizing a Big-Science facility, The European Spallation Source, has successfully managed to present the project as relevant to different national and international policy-makers, to the community of European neutron researchers as well as to different industrial interests. All this has been achieved in a research-policy environment, which has been the subject to drastic transformations, from calls to engage researchers from the former eastern bloc in the early 1990s via competition with American and Asian researchers at the turn of the century 2000 to intensified demands on business applications. During this process, there has also been fierce competition between different potential sites in the U.K., Germany, Spain, Hungary and Sweden, not once, but twice. The project has in addition been plagued by withdrawals of key actors as well as challenging problems in the field of spallation-source construction. Nevertheless, the European Spallation Source has survived from the early 1990s until today, now initiating the construction process at Lund in southern Sweden. In this presentation, the different measures taken and arguments raised by the European Spallation Source project in order to realize the facility will be analysed. Especially the different designs of the European Spallation Source will be analysed as responses to external demands and threats.

‘It’s All Done With Mirrors’: V.S. Ramachandran and the Material Culture of Phantom Limb Research

PubMed Central

Guenther, Katja

2016-01-01

This article examines the material culture of neuroscientist Vilayanur S. Ramachandran’s research into phantom limbs. In the 1990s Ramachandran used a ‘mirror box’ to ‘resurrect’ phantom limbs and thus to treat the pain that often accompanied them. The experimental success of his mirror therapy led Ramachandran to see mirrors as a useful model of brain function, a tendency that explains his attraction to work on ‘mirror neurons’. I argue that Ramachandran’s fascination with and repeated appeal to the mirror can be explained by the way it allowed him to confront a perennial problem in the mind and brain sciences, that of the relationship between a supposedly immaterial mind and a material brain. By producing what Ramachandran called a ‘virtual reality’, relating in varied and complex ways to the material world, the mirror reproduced a form of psycho-physical parallelism and dualistic ontology, while conforming to the materialist norms of neuroscience today.

To analyze the level and trend of diabetes mellitus (DM) in Mexico, and its contribution to the changes in temporary life expectancy between 20 and 100 years of age, in the period 1990-2010. Data comes from National Mortality Vital Statistics and from the Population Census from the Mexican National Institute of Geography and Statistics (INEGI). We calculated standardized mortality rates. To analyze the impact of DM on the temporary life expectancy (80e20) we used Pollard’s method. Between 1990 and 2010, the standardized mortality rate for people 20 years and older increased by 224 %. The contribution of DM for men to the change in life expectancy during 1990-2000 was a reduction of 0.31 years; for women was a reduction of 0.32 years; in the period 2000-2010 the reduction continued for both men and women (0.34 and 0.12 years respectively). Mortality from DM continues to increase, especially for men, but for women a modest reduction was observed. It is essential to apply health services and programs aimed at reducing mortality from this cause, focused on prevention, early detection and timely treatment, with concrete actions on vulnerable groups.

This article applies scientometric techniques to study the evolution of the field of entrepreneurship between 1990 and 2013. Using a combination of topic mapping, author and journal co-citation analyses, and overlay visualization of new and hot topics in the field, this article makes important contribution to the entrepreneurship research by identifying 46 topics in the 24-year history of entrepreneurship research and demonstrates how they appear, disappear, reappear and stabilize over time. It also identifies five topics that are persistent across the 24-year study period--institutions and institutional entrepreneurship, innovation and technology management, policy and development, entrepreneurial process and opportunity, and new ventures--which I labeled as The Pentagon of Entrepreneurship. Overall, the analyses revealed patterns of convergence and divergence and the diversity of topics, specialization, and interdisciplinary engagement in entrepreneurship research, thus offering the latest insights on the state of the art of the field.

Drug company advertising in medical journals about the health-economic advantages of their products for 2000-2006 versus 1990-1999.

Section 114 of the 1997 Food and Drug Administration Modernization Act (FDAMA) effective February 19, 1998, permitted some additional flexibility for drug companies to provide "health care economic information" to "a formulary committee or other similar entity" and may have caused a decline in economic messages used in print advertisements in medical journals. We previously investigated the promotional claims made by pharmaceutical companies about the economic advantages of their prescription products in print advertisements in 6 leading medical journals from 1990-1999. To examine the hypotheses that (1) economic promotion in journals declined after the effective date of Section 114 of the FDAMA, and (2) increased calls for U.S. Food and Drug Administration (FDA) scrutiny of health-economic information was associated with an increase in the reporting of supporting information for economic advertisements in 2000- 2006 compared with the 1990s. Two researchers independently reviewed all pharmaceutical print advertisements in 3 issues each year of 3 general medical and 3 specialty journals (totaling 18 issues each year) from 2000 through 2006. The type of economic claim (e.g., advertisements using the words "price," "costs less," "value") as well as the presence of supporting information for an advertisement's claims (e.g., published studies) were tabulated using a standardized data collection form. The research method was similar to that used in previous research of economic claims in advertisements in the same 6 medical journals from 1990-1999, and we compared the results from previous research for 1990-1999 with the new findings for 2000-2006. The list of health economic terms was expanded in the 2000-2006 research to include "less hospitalization"/"less treatment," "formulary"/"coverage," "co-pay"/"cost-sharing," and "in community longer." Our results are derived from 2,144 pharmaceutical advertisements from the 10-year period 1990-1999 and 1,372 from the 7-year

To study teen birth rates, trends, and socio-demographic and pregnancy characteristics of AI/AN across geographic regions in the US. The birth rate for US teenagers 15-19 years reached a historic low in 2009 (39.1 per 1,000) and yet remains one of the highest teen birth rates among industrialized nations. In the US, teen birth rates among Hispanic, non-Hispanic black, and American Indian/Alaska Native (AI/AN) youth are consistently two to three times the rate among non-Hispanic white teens. Birth certificate data for females younger than age 20 were used to calculate birth rates (live births per 1,000 women) and joinpoint regression to describe trends in teen birth rates by age (<15, 15-17, 18-19) and region (Aberdeen, Alaska, Bemidji, Billings, California, Nashville, Oklahoma, Portland, Southwest). Birth rates for AI/AN teens varied across geographic regions. Among 15-19-year-old AI/AN, rates ranged from 24.35 (California) to 123.24 (Aberdeen). AI/AN teen birth rates declined from the early 1990s into the 2000s for all three age groups. Among 15-17-year-olds, trends were approximately level during the early 2000s-2007 in six regions and declined in the others. Among 18-19-year-olds, trends were significantly increasing during the early 2000s-2007 in three regions, significantly decreasing in one, and were level in the remaining regions. Among AI/AN, cesarean section rates were lower in Alaska (4.1%) than in other regions (16.4-26.6%). This is the first national study to describe regional variation in AI/AN teen birth rates. These data may be used to target limited resources for teen pregnancy intervention programs and guide research.

1991-01-01

The principal responsibility of the Health Resources and Services Administration (HRSA) is to see to it that primary health care services and qualified health personnel and facilities are available to all Americans, particularly the disadvantaged and the underserved. HRSA's resources are directed toward not only the most financially, functionally, and culturally vulnerable segments of the population but also to those who have significant clinical needs such as pregnant women, children, those infected with HIV. The Agency seeks to carry out its mission in many ways. The central approach, however, is to assure the availability of services to its constituencies directly or indirectly through the more than 50 programs it administers. This article explains HRSA's role in detail and cites its many ramifications for the nation's health in the 1990s. PMID:1899941

In the early 1990s, the U.S. Environmental Protection Agency (U.S. EPA) started a grant program to assist communities redevelop brownfields, which are abandoned or underutilized sites that have real or perceived contamination. In addition to determining if the communities receiving the grants were the most distressed cities in the United States, we also evaluate the U.S. EPA program in terms of environmental justice at the macro scale. Using 1990 U.S. Census of Housing and Population data and a matched-cities methodology, we compared the brownfields pilot cities to other communities in the United States. We found that regardless of intent, the U.S. EPA program is environmentally just by disproportionately awarding grants to the most economically distressed cities. We also found that the cities that received funding in the early years of the program were more economically distressed than cities receiving the funding more recently.

Climate change has been recognized as both one of the biggest threats and the biggest opportunities for global health in the 21st century. This trend review seeks to assess and characterize the amount and type of scientific literature on the link between climate change and human health. We tracked the use of climate-related terms and their co-occurrence with health terms during the 25 years since the first Intergovernmental Panel on Climate Change (IPCC) report, from 1990 to 2014, in two scientific databases and in the IPCC reports. We investigated the trends in the number of publications about health and climate change through time, by nature of the health impact under study, and by geographic area. We compared the scientific production in the health field with that of other sectors on which climate change has an impact. The number of publications was extremely low in both databases from 1990 (325 and 1,004, respectively) until around 2006 (1,332 and 4,319, respectively), which has since then increased exponentially in recent years (6,079 and 17,395, respectively, in 2014). However, the number of climate change papers regarding health is still about half that of other sectors. Certain health impacts, particularly malnutrition and non-communicable diseases (NCDs), remain substantially understudied. Approximately two-thirds of all published studies were carried out in OECD countries (Organization for Economic Cooperation and Development), predominantly in Europe and North America. There is a clear need for further research on the links between climate change and health. This pertains particularly to research in and by those countries in which health will be mostly affected and capacity to adapt is least. Specific undertreated topics such as NCDs, malnutrition, and mental health should gain the priority they deserve. Funding agencies are invited to take note of and establish calls for proposals accordingly. Raising the interest in this research area in young

Robinson, Thomas H.

1986-07-01

The continuing trend towards the development and production of aircraft capable of multiple missions indicates that future airborne radars must provide a broad spectrum of air-to-air and air-to-ground modes. This paper investigates the modal and functional requirements of a multimode radar projected for the mid-1990s period. The paper is divided into two sections. In the first, the multimission capabilities of current radars are presented to establish trends and capabilities. In the second, the requirements of the next generation system are established. Current multimode radars lay the basis for future systems. The experience gained on the APG-65 and APG-63/70 radars is presented and conclusions are drawn regarding their impact on future system requirements. Not only are modes and performance reviewed for these radars but also their system architecture. The discussion starts with the APG-65 radar which is the first true multimission radar with programmable signal and data processing. Following this, the evolution of the APG-63 radar, culminating with the most recent upgrading resulting in redesignation of APG-70, is presented. The incorporation of air-to-ground capabilities in the APG-70, resulting from the Dual Role Fighter program, is reviewed. Results from the Advanced Fighter Capabilities Demonstration program are presented showing how high resolution SAR was incorporated into a full weapon delivery solution. The specific radar requirements for the next decade radar system are developed. This development is done in two parts. First, mode requirements are synthesized for air superiority, navigation and strike/interdiction operation. This includes low altitude penetration requirements and a review of radar timeline constraints which arise. Second, the fundamental functional requirements needed to implement the mode requirements are explored. Architectural issues and their impact on reliability and sustainability are also considered.

Tropical forests were the primary sources of new agricultural land in the 1980s and 1990s.

Global demand for agricultural products such as food, feed, and fuel is now a major driver of cropland and pasture expansion across much of the developing world. Whether these new agricultural lands replace forests, degraded forests, or grasslands greatly influences the environmental consequences of expansion. Although the general pattern is known, there still is no definitive quantification of these land-cover changes. Here we analyze the rich, pan-tropical database of classified Landsat scenes created by the Food and Agricultural Organization of the United Nations to examine pathways of agricultural expansion across the major tropical forest regions in the 1980s and 1990s and use this information to highlight the future land conversions that probably will be needed to meet mounting demand for agricultural products. Across the tropics, we find that between 1980 and 2000 more than 55% of new agricultural land came at the expense of intact forests, and another 28% came from disturbed forests. This study underscores the potential consequences of unabated agricultural expansion for forest conservation and carbon emissions.

Atmospheric acid deposition is considered a global environmental issue. China has been experiencing serious acid deposition, which is anticipated to be more serious with the country's economic development and increasing consumption of fossil fuels in recent decades. By collecting nationwide data on pH and concentrations of sulfate (SO42-) and nitrate (NO3-) in precipitation between 1980 and 2014 in China, we explored the spatiotemporal variations of precipitation acid deposition (bulk deposition) and their influencing factors. Our results showed that average precipitation pH values were 4.86 and 4.84 in the 1990s and 2010s, respectively. This suggests that precipitation acid deposition in China has not seriously changes. Average SO42- deposition declined from 30.73 to 28.61 kg S ha-1 yr-1 but average NO3- deposition increased from 4.02 to 6.79 kg N ha-1 yr-1. Specifically, the area of severe precipitation acid deposition in southern China has shrunk to some extent as a result of decreasing pollutant emissions, whereas the area of moderate precipitation acid deposition has expanded in northern China, associated with rapid industrial and transportation development. Significant positive correlations have been found between precipitation acid deposition, energy consumption, and rainfall. Our findings provide a comprehensive evaluation of the spatiotemporal dynamics of precipitation acid deposition in China over past three decades, and confirm the idea that strategies implemented to save energy and reduce pollutant emissions in China have been effective in alleviating precipitation acid deposition. These findings might be used to demonstrate how developing countries could achieve economic development and environmental protection through the implementation of advanced technologies to reduce pollutant emissions.

The increasing use of theory in social gerontology: 1990-2004.

To determine how often theory is used in published research in social gerontology, compare theory use over a 10-year period (1990-1994 to 2000-2004), and identify the theories most frequently used in social gerontology research. Systematic review of articles published in eight leading journals from 2000 to 2004 (N = 1,046) and comparison with a review conducted 10 years earlier. Theory was mentioned in 39% of articles published from 2000 to 2004, representing a 12% increase in the use of theory over 10 years. This increase was driven by theories outside the core sociology of aging theories identified by Bengtson, V. L., Burgess, E. O., and Parrott, T. M. (1997). Theory, explanation, and a third generation of theoretical development in social gerontology. Journal of Gerontology: Social Sciences, 52B, S72-S88. The five most frequently used theories included the life course perspective, life-span developmental theories, role theory, exchange theory, and person-environment theory/ecological theories of aging. Commonly used models included stress process/stress and coping models, successful aging models, the Andersen behavioral model of health services use, models of control/self-efficacy/mastery, and disablement process models. Theory use in social gerontology increased between 1990 and 2004, with a shift toward theories that cross disciplines. However, the majority of research in social gerontology continues to be atheoretical. Models are widely used as a supplement to or substitute for theory. Many of these models are currently being debated and elaborated, and over time, they may emerge as important theoretical contributions to social gerontology.

Delgrosso, E. J.; Zajac, T.; Tseka, J.

1980-10-01

Changes in materials and processes expected to be used in aircraft environmental control systems (ECS) in the 1990s are analyzed, and a forecast is presented. Results of the study show that the most advanced development would be in the use of a cast high strength alloy steel, i.e., a steel with below 8% alloy content, and a 225 KSI annealed tensile strength. To assure complete densification and enhancement of properties, the casting would be HIP, and modification of its surface chemistry could be achieved through ion implantation. As candidate methods for imparting surface protection, laser glazing and chemical vapor deposition are mentioned. The anticipated changes in the materials and techniques used for construction of ECS components are: the development of rapid solidification rate powders for the production of some alloy systems such as Al-Mg-Li, bearing alloy CRB-7, and titanium alloys, 'near-net-shape' processing, and the use of advanced fiber-reinforced plastics.

An Account of Stellar Spectroscopy and John S. Plaskett’s Leadership within Early 20th-Century Astrophysics in Canada

NASA Astrophysics Data System (ADS)

Ihor Oakes, Andrew

2017-01-01

From the perspective of the science of astronomy, the interpretation of the light spectrum was a fundamental development in the chemical analysis of celestial starlight. The breakthrough discovery with the application of spectroscopy in 1859, inaugurated a new period in astronomy that evolved into astrophysics. It launched a continuing episode of new astronomy that was later embraced in early 20th-century Canada where it was spearheaded by Canadian physicist and scientist, John S. Plaskett (1865-1941). The research work of John Plaskett at the Dominion Observatory in Ottawa, Ontario, from 1903 and, later, the Dominion Astrophysical Observatory in Victoria, British Columbia, from 1918, brought international recognition to Canada’s early efforts in astrophysics. Plaskett’s determination and personal boldness led to the establishment of a small cadre of Canadian astronomers who worked on their astrophysical research programs under Plaskett as their supervisor. Despite its small population at the time and a relatively infinitesimal number of professional astronomers, Canada did become recognized for its early spectrographic work in astrophysics, which was due to developing a professional status equal to its international colleagues. Plaskett improved the techniques of celestial spectroscopy during his scientific work at the Dominion Observatory and, again later, at its newly-built sister facility, the Dominion Astrophysical Observatory. Historically, Plaskett found himself to be the right person, in the right place, at the right time, and with the right temperament during the review period spanning 1903 to 1935.

Introduction Alcohol violations by airline pilots are rare yet remain a public concern. Such incidents often generate widespread news coverage. This study examines the frequency and characteristics of alcohol violation incidents involving airline pilots reported in U.S. newspapers. Methods The database of Lexis-Nexis™, which contains full-text articles for over 350 newspapers, was searched to identify alcohol violation incidents involving airline pilots in the U.S. between January 1990 and June 2006. Information pertaining to the pilot, flight, blood alcohol concentration (BAC), and consequence was ascertained for each incident based on the newspaper coverage. Results During the study period, newspapers reported on a total of 13 incidents of alcohol violations involving 17 pilots. All but two of the incidents occurred during January 2002 through June 2006. The majority (85%) of the incidents were first identified by airport personnel, such as security screeners, based on suspicion of alcohol use by the pilot. Subsequent alcohol testing revealed a mean BAC of 90 mg/dL (ranging from 10 mg · dL−1 to 182 mg · dL−1). Of the 17 pilots, 6 were known to be prosecuted criminally, including 5 who were sentenced to jail terms. Discussion Incidents of alcohol violations by airline pilots reported in U.S. newspapers have increased in recent years. This increase is likely due in part to increased detection resulting from enhanced aviation security and enforcement following the September 2001 terrorist attacks. PMID:17183928

Demographics of Investigators Involved in OSSA-Funded Research

1991-01-01

The birth of the U.S. civil space program and the subsequent, dramatic growth in the ranks of the space science research population occurred in the 1950s and 1960s'. The large, post- Sputnik/ Apollo buildup in space program manpower is now approximately one career-lifetime in the past. It is therefore natural to anticipate that a large fraction of the space program engineers, scientists, and managers who pioneered the early exploration of space are approaching retirement. Such a "retirement wave" bodes both a loss of manpower and, more fundamentally, a loss of experience from the civil-space manpower base. Such losses could play a critical role constraining in NASA's ability to expand or maintain its technical capabilities. If this indeed applies to the NASA space science research population, then the potential for problems is exacerbated by the anticipated growth in flight rates, data volume, and data-set diversity which will accompany the planned expansion in the OSSA science effort during the 1990s and 2000s. The purpose of this study was to describe the OSSA PI/Co-I population and to determine the degree to which the OSSA space science investigator population faces a retirement wave, and to estimate the future population of PIs in the 1990-2010 era. To conduct such a study, we investigated the present demographics of the PI and Co-1 population contained in the NASA/OSSA Announcement of Opportunity (AO) mailing list. PIs represent the "leadership" class of the OSSA scientific researcher population, and Co-Is represent one important, oncoming component of the "replacement" generation. Using the PI population data, we then make projection estimates of the future PI population from 1991 through 2010, under various NASA growth/PI demand scenarios.

The early history of ideas on brief interventions for alcohol.

PubMed

McCambridge, Jim; Cunningham, John A

2014-04-01

This study explores the early development of brief interventions for alcohol using a history of ideas approach with a particular focus on intervention content. The source publications of the key primary studies published from approximately 1962 to 1992 were examined, followed by a brief review of the earliest reviews in this field. These studies were placed in the context of developments in alcohol research and in public health. After early pioneering work on brief interventions, further advances were not made until thinking about alcohol problems and their treatment, most notably on controlled drinking, along with wider changes in public health, created new conditions for progress. There was then a golden era of rapid advance in the late 1980s and early 1990s, when preventing the development of problem drinking became important for public health reasons, in addition to helping already problematic drinkers. Many research challenges identified at that time remain to be met. The content of brief interventions changed over the period of study, although not in ways well informed by research advances, and there were also obvious continuities, with a renewed emphasis on the facilitation of self-change being one important consequence of the development of internet applications. Ideas about brief interventions have changed in important ways. Brief interventions have been studied with different populations of drinkers, with aims embracing both individual and population-level perspectives, and without well-specified contents. The brief intervention field is an appropriate target for further historical investigations, which may help thinking about addressing alcohol and other problems. © 2013 The Authors.

1993-01-01

Virtually all of the data distribution strategies being contemplated for the EOSDIS era revolve around the use of files. Most, if not all, mass storage technologies are based around the file model. However, files may be the wrong primary abstraction for supporting scientific users in the 1990s and beyond. Other abstractions more closely matching the respective scientific discipline of the end user may be more appropriate. JPL has built a unique multimission data distribution system based on a strategy of telemetry stream emulation to match the responsibilities of spacecraft team and ground data system operators supporting our nations suite of planetary probes. The current system, operational since 1989 and the launch of the Magellan spacecraft, is supporting over 200 users at 15 remote sites. This stream-oriented data distribution model can provide important lessons learned to builders of future data systems.

An Exploration of Ethical Issues in Research in Children’s Health and the Environment

PubMed Central

Paulson, Jerome A.

2006-01-01

The consideration of ethical issues relating to pediatric environmental health is a recent phenomenon. Discussions of biomedical ethics, research on children, and environmental health research have a longer history. In the late 1990s, researchers at the Kennedy Krieger Institute in Baltimore, Maryland, undertook a study to compare the effectiveness of several methods of reducing lead risk in housing. In a preliminary finding in the case of Grimes v. Kennedy Krieger Institute, Inc., a Maryland court questioned the ethics of performing research on children when there is no prospect of direct benefit to those children and whether parents can consent to such research. This case dramatically raised the profile of ethical issues among the pediatric environmental health research community. To broaden the discussion of these issues and in response to the Kennedy-Krieger case, the Children’s Environmental Health Network held a working meeting on 5 and 6 March 2004 to explore this topic. The articles in this mini-monograph were prepared by the authors as a result of the workshop and represent their opinions. This article is an introduction to the workshop and a summary of the articles to follow. PMID:17035150

Pre-diabetes is a state of beta-cell stress caused by excess demand for insulin. Body mass is an important determinant of insulin demand, and BMI has risen substantially over recent time. We sought to model changes in the parameters of glucose control against rising BMI over the past 25years. Using random coefficient mixed models, we established the correlations between HbA1C, fasting glucose, fasting insulin, HOMA2-IR and BMI in contemporary (2015) children (N=307) at ages 5-16y from the EarlyBird study, and modelled their corresponding values 25years ago according to the distribution of BMI in the UK Growth Standards (1990). There was little change in HbA1C or fasting glucose over the 25y period at any age or in either gender. On the other hand, the estimates for fasting insulin and HOMA2-IR were substantially higher in both genders in 2015 compared with 1990. Insofar as it is determined by body mass, there has been a substantial rise in beta cell demand among children over the past 25years. The change could be detected by fasting insulin and HOMA2-IR, but not by fasting glucose or HbA1C. Crown Copyright © 2016. Published by Elsevier B.V. All rights reserved.

2002-01-01

In the early 1990s, the U.S. Environmental Protection Agency (U.S. EPA) started a grant program to assist communities redevelop brownfields, which are abandoned or underutilized sites that have real or perceived contamination. In addition to determining if the communities receiving the grants were the most distressed cities in the United States, we also evaluate the U.S. EPA program in terms of environmental justice at the macro scale. Using 1990 U.S. Census of Housing and Population data and a matched-cities methodology, we compared the brownfields pilot cities to other communities in the United States. We found that regardless of intent, the U.S. EPA program is environmentally just by disproportionately awarding grants to the most economically distressed cities. We also found that the cities that received funding in the early years of the program were more economically distressed than cities receiving the funding more recently. PMID:11929735

Positivism in sociological research: USA and UK (1966-1990).

PubMed

Gartrell, C David; Gartrell, John W

2002-12-01

Positivism has been declared dead in sociological theory circles, yet questions remain as to its viability among researchers. The authors present diagnostic evidence about positivism in sociological practice through a content analysis of journal articles published in the late 1960s and the late 1980s in the sociological journals of the USA and Britain. Using an index based on seven elements of positivism that were characteristic of the 'theory construction' movement of the late 1960s, the authors find evidence of the effects of time and nation on the use of positivism. Disaggregation of the index reveals that most of the observed change is associated with the elements of 'instrumental' positivism, particularly statistics. The results raise questions about the relationship between theory and research and about sociologists' philosophies of science.

Are the economics of pharmaceutical research and development changing?: productivity, patents and political pressures.

PubMed

Grabowski, Henry

2004-01-01

Pharmaceutical research and development (R&D) competition in the 1980s and 1990 s was characterised by rising R&D expenditures, favourable returns to innovators and the introduction of many new classes of drugs with high social benefits. However, in the past 3 years, the number of new drug introductions has been well below the historical trend, while the cost per new drug continues to increase. In addition to lagging R&D productivity, the industry has been characterised by other economic and policy uncertainties. These include a wave of early patent challenges and growing political pressure to contain pharmaceutical expenditures. This paper examines the consequences of these developments.

Exposures to diesel exhaust in the International Brotherhood of Teamsters, 1950-1990.

PubMed

Bailey, Chad R; Somers, Joseph H; Steenland, Kyle

2003-01-01

A prior case-control study found a positive, monotonic exposure-response relationship between exposure to diesel exhaust and lung cancer among decedents of the Central States Conference of the International Brotherhood of Teamsters. In response to critiques of the Teamsters' exposure estimates by the Health Effects Institute's Diesel Epidemiology Panel, historical exposures and associated uncertainties are investigated here. Historic diesel exhaust exposures are predicted as a function of heavy-duty diesel truck emissions, increasing use of diesel engines, and occupational elemental carbon (EC) measurements taken during the late 1980s and early 1990s. EC from diesel and nondiesel sources is distinguished in light of recent studies indicating a substantial contribution of gasoline vehicles to ambient EC. Monte Carlo sampling is used to characterize exposure distributions. The methodology used in this article-a probabilistic model for historical exposure assessment-is novel.

1994-01-01

This review critically summarizes the literature on the spectrum of health effects of zinc status, ranging from symptoms of zinc deficiency to excess exposure. Studies on zinc intake are reviewed in relation to optimum requirements as a function of age and sex. Current knowledge on the biochemical properties of zinc which are critical to the essential role of this metal in biological systems is summarized. Dietary and physiological factors influencing the bioavailability and utilization of zinc are considered with special attention to interactions with iron and copper status. The effects of zinc deficiency and toxicity are reviewed with respect to specific organs, immunological and reproductive function, and genotoxicity and carcinogenicity. Finally, key questions are identified where research is needed, such as the risks to human health of altered environmental distribution of zinc, assessment of zinc status in humans, effects of zinc status in relation to other essential metals on immune function, reproduction, neurological function, and the cardiovascular system, and mechanistic studies to further elucidate the biological effects of zinc at the molecular level.

Kenny, Joan F.

2014-01-01

This fact sheet describes water-use data collection and quantities of surface water and groundwater diverted for public supply in Kansas for the years 1990 through 2012. Data used in this fact sheet are from the Kansas Department of Agriculture’s Division of Water Resources and the Kansas Water Office. Water used for public supply represents about 10 percent of all reported water withdrawals in Kansas. Between 1990 and 2012, annual withdrawals for public supply ranged from a low of 121 billion gallons in 1993 to a high of 159 billion gallons in 2012. Differences in annual withdrawals were associated primarily with climatic fluctuations. Six suppliers distributed about one-half of the total water withdrawn for public supply, and nearly three-quarters of the surface water. Surface water represented between 52 and 61 percent of total annual withdrawals for public supply. The proportion of surface water obtained through contracts from Federal reservoirs increased from less than 5 percent in the 1990s to 8 percent in 2011 and 2012. More than 99 percent of the reported water withdrawn for public supply in Kansas in 2012 was metered, which was an increase from 92 percent in 1990. State population increased steadily from 2.5 million people in 1990 to 2.9 million in 2012. Recent estimates indicate that about 95 percent of the total population was served by public water supply; the remainder obtained water from other sources such as private wells. Average per capita water use as calculated for State conservation planning purposes varied by region of the State. The smallest regional average water use for the years 1990–2012 was 98 gallons per person per day in easternmost Kansas, and the largest regional average water use was 274 gallons per person per day in westernmost Kansas.

Osteoporosis in survivors of early life starvation.

PubMed

Weisz, George M; Albury, William R

2013-01-01

The objective of this study was to provide evidence for the association of early life nutritional deprivation and adult osteoporosis, in order to suggest that a history of such deprivation may be an indicator of increased risk of osteoporosis in later life. The 'fetal programming' of a range of metabolic and cardiovascular disorders in adults was first proposed in the 1990s and more recently extended to disorders of bone metabolism. Localised famines during World War II left populations in whom the long-term effects of maternal, fetal and infantile nutritional deprivation were studied. These studies supported the original concept of 'fetal programming' but did not consider bone metabolism. The present paper offers clinical data from another cohort of World War II famine survivors - those from the Holocaust. The data presented here, specifically addressing the issue of osteoporosis, report on 11 Holocaust survivors in Australia (five females, six males) who were exposed to starvation in early life. The cases show, in addition to other metabolic disorders associated with early life starvation, various levels of osteoporosis, often with premature onset. The cohort studied is too small to support firm conclusions, but the evidence suggests that the risk of adult osteoporosis in both males and females is increased by severe starvation early in life - not just in the period from gestation to infancy but also in childhood and young adulthood. It is recommended that epidemiological research on this issue be undertaken, to assist planning for the future health needs of immigrants to Australia coming from famine affected backgrounds. Pending such research, it would be prudent for primary care health workers to be alert to the prima facie association between early life starvation and adult osteoporosis, and to take this factor into account along with other indicators when assessing a patient's risk of osteoporosis in later life.

The Formation of a Socioeconomic Health Disparity: The Case of Cocaine Use during the 1980s and 1990s*

PubMed Central

MIECH, RICHARD

2017-01-01

Despite the substantial and prolonged sociological interest in health disparities, much remains unknown about the processes that initiate them. To investigate this topic, we focus on the case study of cocaine use, for which a socioeconomic disparity emerged across all age groups in a short period of time around 1990. We examine whether the newly-formed disparity represents a selective remnant of previous users or, instead, a selective recruitment of new users. To evaluate these two potential processes we use latent class regression on a nationally representative cohort with repeated measures of past-year cocaine use before and after1990. Results support the “remnant” hypothesis and show that the newly-formed disparity resulted primarily because people in the lower social strata were less likely to have a trajectory of cocaine use with a sharp drop in use after 1990. These results point to the “remnant” concept as a way to bring together disparity analysis of very different and diverse health outcomes. PMID:18771068

Since the early 1990s former communist countries have been reforming their health care systems, emphasizing the key role of primary care and recognizing family medicine as a specialty and an academic discipline. This study assesses the level of academic development of the discipline characterised by education and research in central and eastern European (CEE) countries. A key informants study, using a questionnaire developed on the basis of a systematic literature review and panel discussions, conducted in 11 central and eastern European countries and Russia. Family medicine in CEE countries is now formally recognized as a medical specialty and successfully introduced into medical training at undergraduate and postgraduate levels. Almost all universities have FM/GP departments, but only a few of them are led by general practitioners. The specialist training programmes in all countries except Russia fulfil the recommendations of the European Parliament. Structured support for research in FM/GP is not always available. However specific scientific organisations function in almost all countries except Russia. Scientific conferences are regularly organised in all the countries, but peer-reviewed journals are published in only half of them. Family medicine has a relatively strong position in medical education in central and eastern Europe, but research in family practice is less developed. Although the position of the discipline at the universities is not very strong, most of the CEE countries can serve as an example of successful academic development for countries southern Europe, where family medicine is still not fully recognised.

Boxing injuries can have serious consequences. To examine the epidemiology of boxing injuries in the U.S. with attention to head injuries and children. National estimates of boxing injuries were calculated using data from the National Electronic Injury Surveillance System. Injury rates per 1000 participants for the year 2003 were calculated using boxing participation data. Data analysis was conducted in 2009-2010. An estimated 165,602 individuals (95% CI=134891, 196313) sustained boxing injuries that resulted in a visit to a U.S. hospital emergency department from 1990 through 2008. An average of 8716 (95% CI=7078, 10354) injuries occurred annually, and there was a statistically significant increase in the annual number of injuries during the 19-year study period (slope=610, p<0.001). The rate of injury was 12.7 per 1000 participants. Those injured were predominately male (90.9%). The most common diagnosis was fracture (27.5%), and the most common body regions injured were the hand (33.0%) and head and neck (22.5%). Punching bag-related injuries accounted for 36.8% of boxing injuries. The percentage of injuries that were concussions/closed head injuries in the group aged 12-17 years (8.9%) was similar to that in the group aged 18-24 years (8.1%) and the group aged 25-34 years (8.5%). These findings, based on a nationally representative sample, indicate that injuries related to boxing are increasing in number. Increased efforts are needed to prevent boxing injuries.

Interfacing 1990 US Census TIGER map files with New S graphics software

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

Rizzardi, M.; Mohr, M.S.; Merrill, D.W.

1992-07-01

In 1990, the United States Bureau of the Census released detailed geographic base files known as TIGER/Line (Topologically Integrated Geographic Encoding and Referencing) which contain detail on the physical features and census tract boundaries of every county in the United States. The TIGER database is attractive for two reasons. First, it is publicly available through the Bureau of the Census on tape or cd-rom for a minimal fee. Second, it contains 24 billion characters of data which describe geographic features of interest to the Census Bureau such as coastlines, hydrography, transportation networks, political boundaries, etc. Unfortunately, the large TIGER databasemore » only provides raw alphanumeric data; no utility software, graphical or otherwise, is included. On the other hand New S, a popular statistical software package by AT&T, has easily operated functions that permit advanced graphics in conjunction with data analysis. New S has the ability to plot contours, lines, segments, and points. However, of special interest is the New S function map and its options. Using the map function, which requires polygons as input, census tracts can be quickly selected, plotted, shaded, etc. New S graphics combined with the TIGER database has obvious potential. This paper reports on our efforts to use the TIGER map files with New S, especially to construct census tract maps of counties. While census tract boundaries are inherently polygonal, they are not organized as such in the TIGER database. This conversion of the TIGER ``line`` format into New S ``polygon/polyline`` format is one facet of the work reported here. Also we discuss the selection and extraction of auxiliary geographic information from TIGER files for graphical display using New S.« less

Natural family planning in the 1990s.

PubMed

Ryder, B; Campbell, H

1995-07-22

Natural family planning (NFP) tends to be considered as a matter of chance resulting in unplanned pregnancies and large families. A World Health Organization (WHO) multicenter trial of the ovulation method of NFP was undertaken during 1975-79 with the primary objective of determining what proportion of women of many different cultures could be taught to recognize changes in the cervical mucus around the time of ovulation. The conclusions were that: a) irrespective of cultural, educational, or economic background, over 95% of fertile women could recognize the mucus signs of fertility; b) the fertility rate was 22.6 pregnancies per 100 woman years; c) the preovulatory and postovulatory days designated by the ovulation method of NFP rules as infertile were indeed infertile, as the pregnancies in this phase were 4 per 1000 acts of intercourse. The knowledge gained through the WHO trial and subsequent experience has given NFP organizations and teachers a much greater understanding of the fertile and infertile phases, so that total pregnancy rates have been steadily falling. Of the 11 NFP studies so far reported in the 1990s, the 3 that had total pregnancy rates greater than 5 per 100 woman years were trials of atypical NFP approaches or teaching methods. The results can be compared with reported pregnancy rates of between 0.18 and 3.6 for artificial contraceptive methods in well-motivated couples. One criticism of NFP is that the necessary periods of abstinence may be detrimental to the marital relationship. It is suggested that the sexual revolution of the last 20-30 years has caused marital and family breakdown on a massive scale, thus NFP might be the antidote. Since women are potentially fertile for no more than 6-8 days in the cycle, these easily recognized symptoms empower women through the knowledge they impart regarding their state of fertility. All women are entitled to this simple and fundamental information.

Tobacco industry consumer research on smokeless tobacco users and product development.

PubMed

Mejia, Adrienne B; Ling, Pamela M

2010-01-01

Since 2006, RJ Reynolds (RJR) and Philip Morris have both introduced new smokeless "snus" tobacco products. We analyzed previously secret tobacco industry documents describing the history of RJR and Philip Morris's consumer research, smokeless product development, and marketing strategies. We found that RJR had invested in smokeless research, development, and marketing since 1968. RJR first targeted low-income males through sampling and sponsorship at fishing, rodeo, and baseball events, and through advertising portraying the user as "hard working." In the early 1990s, Philip Morris and RJR hoped to attract more urban, female smokeless users. The current "snus" campaigns appear to appeal to these targeted consumers and smokers in smoke-free environments. These efforts may expand the tobacco market and undermine smoking cessation.

Robbins, Chandler S.

1993-01-01

Arthur Bernard Singer was born 4 December 1917, and died 6 April 1990. Although brought up in New York City, Arthur developed an early fascination with birds. His favorite haunts were the Bronx Zoo and the American Museum of Natural History, where Robert Cushman Murphy encouraged his efforts and where Arthur acquired a worldwide perspective. After graduating from Cooper Union Art School in New York City in 1939, he began his career as an art teacher, art director, and designer, His real interest, however, was in depicting the postures and plumages of birds and mammals. As early as 1941 his wildlife art was exhibited at the Bronx Zoo. While he was in the army, his wife Edith (“Judy”) helped mount this first exhibit; Arthur never saw the show.

Mapping the evolution of entrepreneurship as a field of research (1990–2013): A scientometric analysis

PubMed Central

2018-01-01

This article applies scientometric techniques to study the evolution of the field of entrepreneurship between 1990 and 2013. Using a combination of topic mapping, author and journal co-citation analyses, and overlay visualization of new and hot topics in the field, this article makes important contribution to the entrepreneurship research by identifying 46 topics in the 24-year history of entrepreneurship research and demonstrates how they appear, disappear, reappear and stabilize over time. It also identifies five topics that are persistent across the 24-year study period––institutions and institutional entrepreneurship, innovation and technology management, policy and development, entrepreneurial process and opportunity, and new ventures––which I labeled as The Pentagon of Entrepreneurship. Overall, the analyses revealed patterns of convergence and divergence and the diversity of topics, specialization, and interdisciplinary engagement in entrepreneurship research, thus offering the latest insights on the state of the art of the field.

Multiple-Locus Variable-Number Tandem Repeat Analysis of Dutch Bordetella pertussis Strains Reveals Rapid Genetic Changes with Clonal Expansion during the Late 1990s

PubMed Central

Schouls, Leo M.; van der Heide, Han G. J.; Vauterin, Luc; Vauterin, Paul; Mooi, Frits R.

2004-01-01

Bordetella pertussis, the causative agent of whooping cough, has remained endemic in The Netherlands despite extensive nationwide vaccination since 1953. In the 1990s, several epidemic periods have resulted in many cases of pertussis. We have proposed that strain variation has played a major role in the upsurges of this disease in The Netherlands. Therefore, molecular characterization of strains is important in identifying the causes of pertussis epidemiology. For this reason, we have developed a multiple-locus variable-number tandem repeat analysis (MLVA) typing system for B. pertussis. By combining the MLVA profile with the allelic profile based on multiple-antigen sequence typing, we were able to further differentiate strains. The relationships between the various genotypes were visualized by constructing a minimum spanning tree. MLVA of Dutch strains of B. pertussis revealed that the genotypes of the strains isolated in the prevaccination period were diverse and clearly distinct from the strains isolated in the 1990s. Furthermore, there was a decrease in diversity in the strains from the late 1990s, with a remarkable clonal expansion that coincided with the epidemic periods. Using this genotyping, we have been able to show that B. pertussis is much more dynamic than expected. PMID:15292152
