Strategies for managing the effects of urban development on streams

Cappiella, Karen; Stack, William P.; Fraley-McNeal, Lisa; Lane, Cecilia; McMahon, Gerard

2012-01-01

Urban development remains an important agent of environmental change in the United States. The U.S. population grew by 17 percent from 1982 to 1997, while urbanized land area grew by 47 percent, suggesting that urban land consumption far outpaced population growth (Fulton and others, 2001; Sierra Club, 2003; American Farmland Trust, 2009). Eighty percent of Americans now live in metropolitan areas. Each American effectively occupies about 20 percent more developed land (for housing, schools, shopping, roads, and other related services) than 20 years ago (Markham and Steinzor, 2006). Passel and Cohn (2008) predict a dramatic 48 percent increase in the population of the United States from 2005 to 2050. The advantages and challenges of living in these developed areas—convenience, congestion, employment, pollution—are part of the day-to-day realities of most Americans. Nowhere are the environmental changes associated with urban development more evident than in urban streams. The U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program investigation of the effects of urban development on stream ecosystems (EUSE) during 1999–2004 provides the most spatially comprehensive analysis of stream impacts of urban development that has been completed in the United States. A nationally consistent study design was used in nine metropolitan areas of the United States—Portland, Oregon; Salt Lake City, Utah; Birmingham, Alabama; Atlanta, Georgia; Raleigh, North Carolina; Boston, Massachusetts; Denver, Colorado; Dallas, Texas; and Milwaukee, Wisconsin. A summary report published as part of the EUSE study describes several of these impacts on urban streams (Coles and others, 2012).

Health care administration in the United States and Canada: micromanagement, macro costs.

Woolhandler, Steffie; Campbell, Terry; Himmelstein, David U

2004-01-01

A decade ago, U.S. health administration costs greatly exceeded Canada's. Have the computerization of billing and the adoption of a more business-like approach to care cut administrative costs? For the United States and Canada, the authors calculated the 1999 administrative costs of health insurers, employers' health benefit programs, hospitals, practitioners' offices, nursing homes, and home care agencies; they analyzed published data, surveys of physicians, employment data, and detailed cost reports filed by hospitals, nursing homes, and home care agencies; they used census surveys to explore time trends in administrative employment in health care settings. Health administration costs totaled at least dollar 294.3 billion, dollar 1,059 per capita, in the United States vs. dollar 9.4 billion, dollar 307 per capita, in Canada. After exclusions, health administration accounted for 31.0 percent of U.S. health expenditures vs. 16.7 percent of Canadian. Canada's national health insurance program had an overhead of 1.3 percent, but overhead among Canada's private insurers was higher than in the U.S.: 13.2 vs. 11.7 percent. Providers' administrative costs were far lower in Canada. Between 1969 and 1999 administrative workers' share of the U.S. health labor force grew from 18.2 to 27.3 percent; in Canada it grew from 16.0 percent in 1971 to 19.1 percent in 1996. Reducing U.S. administrative costs to Canadian levels would save at least dollar 209 billion annually, enough to fund universal coverage.

Mosquito control in the 21st century faces the challenge of emerging pathogens, invasive mosquito species, and balancing concerns about the environment with effective control strategies.

Major Challenges Limiting Liver Transplantation in the United States

2011-01-01

Liver transplantation is the gold standard of care in patients with end-stage liver disease and those with tumors of hepatic origin in the setting of liver dysfunction. From 1988 to 2009, liver transplantation in the United States grew 3.7-fold from 1713 to 6320 transplants annually. The expansion of liver transplantation is chiefly driven by scientific breakthroughs that have extended patient and graft survival well beyond those expected 50 years ago. The success of liver transplantation is now its primary obstacle, as the pool of donor livers fails to keep pace with the growing number of patients added to the national liver transplant waiting list. This review focuses on three major challenges facing liver transplantation in the United States and discusses new areas of investigation that address each issue: 1) the need for an expanded number of useable donor organs, 2) the need for improved therapies to treat recurrent hepatitis C after transplantation and 3) the need for improved detection, risk stratification based upon tumor biology and molecular inhibitors to combat hepatocellular carcinoma.

The wildland-urban interface (WUI) is the area where houses and wildland vegetation meet or intermingle, and where wildfire problems are most pronounced. Here we report that the WUI in the United States grew rapidly from 1990 to 2010 in terms of both number of new houses (from 30.8 to 43.4 million; 41% growth) and land area (from 581,000 to 770,000 km 2 ; 33% growth), making it the fastest-growing land use type in the conterminous United States. The vast majority of new WUI areas were the result of new housing (97%), not related to an increase in wildland vegetation. Within the perimeter of recent wildfires (1990-2015), there were 286,000 houses in 2010, compared with 177,000 in 1990. Furthermore, WUI growth often results in more wildfire ignitions, putting more lives and houses at risk. Wildfire problems will not abate if recent housing growth trends continue.

In 2010-2012, the controversy over fracking grew rapidly, first in the United States, and then internationally. An important step was the anti-fracking documentary film Gasland. With help from celebrity sources, the film was produced and won a prize at the Sundance Film Festival by early 2010 and had an Oscar nomination by early 2011, in the meantime popularizing potent images of hazard including tainted aquifers and ignitable water running from kitchen faucets. During this period, major US news organizations paid little attention to the issue. The offshore Deepwater Horizon disaster of April 2010 spurred The New York Times to prolific reporting on potential risks of the new onshore technique for extracting shale gas. With flagship news coverage, the controversy had by 2012 gained wide media attention that evoked public concern and opposition, spreading from the United States to other nations. © The Author(s) 2014.

Additionally, English-speaking Latino parents reported higher anxiety and stress compared to both Spanish-speaking Latino and non-Latino white parents (p's < 0.05), whereas Spanish-speaking Latino and non-Latino white parents reported similar levels of stress and anxiety. Results of the current study were consistent with the immigrant health paradox in that more acculturated Latino parents reported higher levels of anxiety and stress than less acculturated Latino and non-Latino white parents, supporting the need for culturally tailored interventions in the perioperative environment.

Bacterial Contamination of Hospital Bed-Control Handsets in a Surgical Setting: A Potential Marker of Contamination of the Healthcare Environment

PubMed Central

Brady, RRW; Kalima, P; Damani, NN; Wilson, RG; Dunlop, MG

2007-01-01

INTRODUCTION Patients undergoing colorectal surgical resections have a high incidence of surgical site infection (SSI). Many patient-specific risk factors have been recognised in association with SSI in such patients, but environmental contamination is increasingly recognised as a contributor to hospital-acquired infection (HAI). This study set out to describe the bacterial contamination of the patient environment, using hospital bed-control handsets, as they are frequently handled by both staff and patients and represent a marker of environmental contamination. PATIENTS AND METHODS On two unannounced sampling events, 1 week apart, 140 bacteriological assessments were made of 70 hospital bed control handsets within a specialist colorectal surgical unit. RESULTS Of the handsets examined, 67 (95.7%) demonstrated at least one bacterial species (52.9% grew 1, 30% grew 2 and 12.9% grew 3 or more bacterial species). Of these, 29 (41.4%) bed-control handsets grew bacteria known to cause nosocomial infection, including 22 (31.4%) handsets which grew Enterococcus spp., 9 (12.9%) which grew MRSA, 2 (2.9%) which grew MSSA, 2 (2.9%) which grew coliforms, and 1 (1.4%) handset which grew anaerobes. At 1-week follow-up, 31 bed-control handsets showed evidence of contamination by the same bacterial species. CONCLUSIONS This study revealed high levels of bacteria known to cause HAI, contaminating hospital bed-control handsets in a surgical setting. Further study is now required to confirm whether hospital environmental contamination is causally involved in SSI. PMID:17959000

The United States differed from other countries by continuing a private market in health, with many self-centred and competing providers and insurers; and its prevailing school of health economics deplored the national health insurance and national health services that were universal in other countries and recommended devices that would eliminate "market failure" in health. When health economics grew in Europe during the 1970s and 1980s, the reformers' first presumption was that the voluminous American market-oriented literature must offer answers; but much of it proved superfluous, since European health care systems still had much competition and consumer choice, and they worked better than the reality in the United States. The United States itself has paid a heavy price for turning over health financing policy to the devotees of microeconomics and free markets, and today its serious problems in health are unsolved. So powerful is the pro-competitive ideology that it has now been adopted by the Democratic Clinton Administration, contradicting the heritage of Roosevelt, Truman, and Johnson.

Applying the Ce-in-zircon oxygen geobarometer to diverse silicic magmatic systems

NASA Astrophysics Data System (ADS)

Claiborne, L. L.; Miller, C. F.

Zircon provides information on age, temperature, and composition of the magma from which it grew. In systems such as Mount St. Helens, where zircon is not coeval with the rest of the crystal cargo, it provides the only accessible record of the extended history of the magmatic system, including cycles of intrusion, crystallization and rejuvenation beneath an active volcano (Claiborne et al., 2010). The rare earth elements, which are present in measureable quantities in zircon, provide information about the composition of the magma from which zircon grew. Unique among the generally trivalent rare earth elements, cerium can exist as either trivalent or tetravalent, depending on the oxidation state of the magma. The tetravalent ion is highly compatible in zircon, in the site that usually hosts tetravalent zirconium, and so the amount of Cerium in zircon relative (relative to what would be expected of trivalent Ce) depends the oxidation state of the magma from which it grew. Trail et al. (2011) proposed a calibration based on experimental data that uses the Ce anomaly in zircon as a direct proxy for magma oxidation (fugacity), describing the relationship between Ce in zircon and magma oxygen fugacity as ln(Ce/Ce*)D = (0.1156±0.0050)xln(fO2)+(13860±708)/T-(6.125±0.484). For systems like Mount St. Helens, where the major minerals record only events in the hundreds to thousands of years leading to eruption, (including the Fe-Ti oxides traditionally relied upon for records of oxidation state of the magmas), this presents a novel approach for understanding more extended histories of oxidation of magmas in the tens and hundreds of thousands of years of magmatism at a volcanic center. This calibration also promises to help us better constrain conditions of crystallization in intrusive portions of volcanic systems, as well as plutonic bodes. We apply this new oxygen geobarometer to natural volcanic and plutonic zircons from a variety of tectonic settings, and compare to existing indicators of oxidation state for each system, as available. Zircons included this study are from Mount St. Helens (ΔNNO +1.5 log units; Smith, 1984), the Peach Spring Tuff and Spirit Mountain Batholith (sphene-bearing, silicic, Miocene-aged rocks from the Colorado River Extensional Corridor), Alid Volcano in Eritrea, and rhyolites and granites from Iceland. Median log fO2 for these systems, calculated from the Cerium anomaly in zircons following Trail et al. (2011) using temperatures from Ti-in-zircon thermometry (Ferry and Watson, 2007) are as follows: Alid -12 bars (ΔNNO +3 log units) at 750 degrees C; Iceland -11 bars (ΔNNO +3 log units) at 800 degrees C; Mount St. Helens -8.6 bars (ΔNNO +6 log units) at 750 degrees C; Peach Spring Tuff -3.4 (ΔNNO +10 log units) at 830 degrees C. While ubiquitous sphene in the Spirit Mountain granites suggest relatively high fO2, calculations based on the cerium anomaly in zircon suggest median log fO2 of >0 at 770 degrees C, which is certainly erroneous. While median values for our natural zircons are, for the most part, above expected fugacities for each system when compared with other indicators, and extreme values for each system are almost certainly erroneous, many are within expected values for terrestrial magmas and they vary relative to one another as might be expected given the magma types and tectonic settings.

Streptococcus suis meningoencephalitis is a rare but increasingly important condition. Good history taking will give clues to the diagnosis. This is the fourth case report in the United States. A 52-year-old Filipino man who recently returned from a trip to the Philippines was admitted with classic symptoms of bacterial meningitis. His cerebrospinal fluid culture grew Streptococcus suis. His clinical course was complicated by seizures, hearing loss, and permanent tinnitus. Clinicians should be aware of this emerging disease especially in patients with recent travel history to endemic areas. Early recognition and appropriate management could potentially prevent complications.

Aerospace Meteorology Lessons Learned Relative to Aerospace Vehicle Design and Operations

NASA Technical Reports Server (NTRS)

Vaughan, William W.; Anderson, B. Jeffrey

2004-01-01

Aerospace Meteorology came into being in the 1950s as the development of rockets for military and civilian usage grew in the United States. The term was coined to identify those involved in the development of natural environment models, design/operational requirements, and environment measurement systems to support the needs of aerospace vehicles, both launch vehicles and spacecraft. It encompassed the atmospheric environment of the Earth, including Earth orbit environments. Several groups within the United States were active in this area, including the Department of Defense, National Aeronautics and Space Administration, and a few of the aerospace industry groups. Some aerospace meteorology efforts were similar to those being undertaken relative to aviation interests. As part of the aerospace meteorology activities a number of lessons learned resulted that produced follow on efforts which benefited from these experiences, thus leading to the rather efficient and technologically current descriptions of terrestrial environment design requirements, prelaunch monitoring systems, and forecast capabilities available to support the development and operations of aerospace vehicles.

This study analyzed various organic fertilizers for indicator microorganisms, pathogens, and antibiotic-resistant Escherichia coli, and evaluated the growth potential of E. coli O157:H7 and Salmonella in fertilizers. A microbiological survey was conducted on 103 organic fertilizers from across the United States. Moisture content ranged from approximately 1% to 86.4%, and the average pH was 7.77. The total aerobic mesophiles ranged from approximately 3 to 9 log colony-forming units (CFU)/g. Enterobacteriaceae populations were in the range of <1 to approximately 7 log CFU/g, while coliform levels varied from <1 to approximately 6 log CFU/g. Thirty samples (29%) were positive for E. coli, with levels reaching approximately 6 log CFU/g. There were no confirmed positives for E. coli O157:H7, Salmonella, or Listeria monocytogenes. The majority of E. coli isolates (n=73), confirmed by glutamate decarboxylase (gad) PCR, were from group B1 (48%) and group A (32%). Resistance to 16 antibiotics was examined for 73 E. coli isolates, with 11 isolates having resistance to at least one antibiotic, 5 isolates to ≥ 2 antibiotics, and 2 isolates to ≥ 10 antibiotics. In the presence of high levels of background aerobic mesophiles, Salmonella and E. coli O157:H7 grew approximately 1 log CFU/g within 1 day of incubation in plant-based compost and fish emulsion-based compost, respectively. With low levels of background aerobic mesophiles, Salmonella grew approximately 2.6, 3.0, 3.0, and 3.2 log CFU/g in blood, bone, and feather meals and the mixed-source fertilizer, respectively, whereas E. coli O157:H7 grew approximately 4.6, 4.0, 4.0, and 4.8 log CFU/g, respectively. Our results revealed that the microbiological quality of organic fertilizers varies greatly, with some fertilizers containing antibiotic resistant E. coli and a few supporting the growth of foodborne pathogens after reintroduction into the fertilizer.

Objectives. We describe long-term trends in the characteristics of foreign-trained new entrants to the registered nurse (RN) workforce in the United States. Methods. Using the 1990 and 2000 US Census 5% Public Use Microdata Sample files, we compared trends in characteristics of US- and foreign-trained new entrants to the RN labor force (n=40827) and identified trends in the country of origin of the foreign-trained new entrants. Results. Foreign-trained RNs grew as a percentage of new entrants to the RN workforce, from 8.8% in 1990 to 15.2% in 2000. Compared with US-trained RNs, foreign-trained RNs were 3 times as likely to work in nursing homes and were more likely to have earned a bachelor’s degree. In 2000, 21% of foreign-trained RNs originated from low-income countries, a doubling of the rate since 1990. Conclusions. Foreign-trained RNs now account for a substantial and growing proportion of the US RN workforce. Our findings suggest foreign-trained RNs entering the United States are not of lower quality than US-trained RNs. However, growth in the proportion of RNs from low-income countries may have negative consequences in those countries. PMID:17395844

This report considers changes to the copper and copper scrap industries of the United States. For the study period, 1995 through 2014, U.S. refined copper production from all sources (primary and secondary materials) decreased from 2.28 million metric tons (Mt) of copper to 1.05 Mt (a 54 percent decrease). During the same period, U.S. copper scrap net exports increased from 0.203 Mt to 0.737 Mt (a 263 percent increase and a compound annual growth rate of about 7.0 percent per year). Copper and copper scrap prices (in constant 2014 dollars) rose such that 2014 prices were about 48 percent greater than 1995 prices. From 1995 through 2014, Chinese imports of copper scrap from the United States grew from 0.061 Mt to 0.569 Mt (an increase of about 830 percent and a compound annual growth rate of about 12.5 percent per year). In 2011, Chinese imports of U.S. copper scrap peaked at 0.745 Mt of contained copper. In 1995, Chinese imports of U.S. copper scrap accounted for 17 percent of U.S. copper scrap exports. By 2014, Chinese imports accounted for 69 percent of U.S. copper scrap exports (by weight), and Chinese imports of U.S. copper scrap were valued at $1.45 billion.

A century of sprawl in the United States

The urban street network is one of the most permanent features of cities. Once laid down, the pattern of streets determines urban form and the level of sprawl for decades to come. We present a high-resolution time series of urban sprawl, as measured through street network connectivity, in the United States from 1920 to 2012. Sprawl started well before private car ownership was dominant and grew steadily until the mid-1990s. Over the last two decades, however, new streets have become significantly more connected and grid-like; the peak in street-network sprawl in the United States occurred in ∼1994. By one measure of connectivity, the mean nodal degree of intersections, sprawl fell by ∼9% between 1994 and 2012. We analyze spatial variation in these changes and demonstrate the persistence of sprawl. Places that were built with a low-connectivity street network tend to stay that way, even as the network expands. We also find suggestive evidence that local government policies impact sprawl, as the largest increases in connectivity have occurred in places with policies to promote gridded streets and similar New Urbanist design principles. We provide for public use a county-level version of our street-network sprawl dataset comprising a time series of nearly 100 y. PMID:26080422

Physician referrals play a central role in ambulatory care in the United States; however, little is known about national trends in physician referrals over time. The objective of this study was to assess changes in the annual rate of referrals to other physicians from physician office visits in the United States from 1999 to 2009. We analyzed nationally representative cross-sections of ambulatory patient visits in the United States, using a sample of 845 243 visits from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey from 1993 to 2009, focusing on the decade from 1999 to 2009. The main outcome measures were survey-weighted estimates of the total number and percentage of visits resulting in a referral to another physician across several patient and physician characteristics. From 1999 to 2009, the probability that an ambulatory visit to a physician resulted in a referral to another physician increased from 4.8% to 9.3% (P < .001), a 94% increase. The absolute number of visits resulting in a physician referral increased 159% nationally during this time, from 41 million to 105 million. This trend was consistent across all subgroups examined, except for slower growth among physicians with ownership stakes in their practice (P = .02) or those with the majority of income from managed care contracts (P = .007). Changes in referral rates varied according to the principal symptoms accounting for patients' visits, with significant increases noted for visits to primary care physicians from patients with cardiovascular, gastrointestinal, orthopedic, dermatologic, and ear/nose/throat symptoms. The percentage and absolute number of ambulatory visits resulting in a referral in the United States grew substantially from 1999 to 2009. More research is necessary to understand the contribution of rising referral rates to costs of care.

Inulin-type fructans are the most studied prebiotic compounds because of their broad range of health benefits. In particular, plants of the Agave genus are rich in fructans. Agave-derived fructans have a branched structure with both β-(2→1) and β-(2→6) linked fructosyl chains attached to the sucrose start unit with a degree of polymerization (DP) of up to 80 fructose units. The objective of this work was to assess the prebiotic potential of three Agave angustifolia Haw fructan fractions (AFF) with different degrees of polymerization. The three fructan fractions were extracted from the agave stem by lixiviation and then purified by ultrafiltration and ion exchange chromatography: AFF1, AFF2 and AFF3 with high (3-60 fructose units), medium (2-40) and low (2-22) DP, respectively. The fructan profile was determined with high-performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD), which confirmed a branched fructan structure. Structural elucidation was performed by Fourier Transform Infra-Red Spectroscopy. The AFF spectrum shows characteristic fructan bands. The prebiotic effect of these fractions was assessed in vitro through fermentation by Bifidobacterium and Lactobacillus strains. Four growth patterns were observed. Some bacteria did not grow with any of the AFF, while other strains grew with only AFF3. Some bacteria grew according to the molecular weight of the AFF and some grew indistinctly with the three fructan fractions.

Introduction In recent years, self-reported cigarette smoking has declined among youth and adults, while electronic cigarette (e-cigarette) use has increased. However, sales trends for these products are less certain. This study assessed national and state patterns of U.S. cigarette and e-cigarette unit sales. Methods Trends in cigarette and e-cigarette unit sales were analyzed using retail scanner data from September 25, 2011 through January 9, 2016 for: (1) convenience stores; and (2) all other outlets combined, including supermarkets, mass merchandisers, drug, dollar, and club stores, and military commissaries (online, tobacco-only, and “vape“ shops were not available). Data by store type were available for the total contiguous U.S. and 29 states; combined data were available for the remaining states, except Alaska, Hawaii, and DC. Results During 2011–2015, cigarette sales exhibited a small, significant decrease; however, positive year-over-year growth occurred in convenience stores throughout most of 2015. E-cigarette unit sales significantly increased during 2011–2015, but year-over-year growth slowed and was occasionally negative. Cigarette unit sales exceeded e-cigarettes by 64:1 during the last 4-week period. During 2014–2015, cigarette sales increases occurred in 15 of 48 assessed states; e-cigarette sales increased in 18 states. Conclusions Despite overall declines during 2011–2015, cigarette sales in 2015 grew for the first time in a decade. E-cigarette sales growth was positive, but slowed over the study period in assessed stores. Cigarette sales continued to exceed e-cigarette sales, reinforcing the importance of efforts to reduce the appeal and accessibility of cigarettes and other combusted tobacco products. PMID:28285828

The United States invests a sizable amount of money on treatments for mental health and substance abuse: $135 billion in 2005, or 1.07 percent of the gross domestic product. We provide treatment spending estimates from the period 1986-2005 to build understanding of past trends and consider future possibilities. We find that the growth rate in spending on mental health medications-a major driver of mental health expenditures in prior years-declined dramatically. As a result, mental health and substance abuse spending grew at a slightly slower rate than gross domestic product in 2004 and 2005, and it continued to shrink as a share of all health spending. Of note, we also find that Medicaid's share of total spending on mental health grew from 17 percent in 1986 to 27 percent in 2002 to 28 percent in 2005. The recent recession, the full implementation of federal parity law, and such health reform-related actions as the planned expansion of Medicaid all have the potential to improve access to mental health and substance abuse treatment and to alter spending patterns further. Our spending estimates provide an important context for evaluating the effect of those policies.

Yellow bullhead (Ictaluridae: Ameiurus natalis) is the most abundant ictalurid catfish in the Everglades of southern Florida, USA, and, as both prey and predator, is one of many essential components in the ecological-simulation models used in assessing restoration success in the Everglades. Little is known of its biology and life history in this southernmost portion of its native range; the present study provides the first estimates of age and growth from the Everglades. In total, 144 yellow bullheads of 97-312 mm total length (TL) were collected from canals and marshes of the Everglades between April 2000 and January 2001, and from October 2003 to February 2005. Fish were aged using cross-sections of pectoral spines and ranged from 1-12 years, with the maximum age almost twice that of any yellow bullhead previously reported. Yellow bullheads from south Florida grew relatively rapidly during their first 3 years, but after age 5 growth slowed and fish approached an asymptote of ???214 mm TL. Compared to other populations in the United States, yellow bullhead in the Everglades grew relatively slowly, were smaller at age overall, but survived to older ages. ?? 2009 Blackwell Verlag GmbH.

To establish the characteristics of published interventional oncology (IO) research, including the volume, growth, geographic distribution, type of research, and funding patterns, and to determine how IO research compares with overall radiology research. This retrospective bibliometric analysis of public data was exempt from Institutional Review Board approval. IO articles published between 1996 and 2008 were identified in the National Library of Medicine MEDLINE database. Country of origin, article methodology, study topic, and source of funding were recorded. Growth was analyzed by using linear and nonlinear regression. Total journal articles numbered 3801, including 847 (22.3%) from the United States, 722 (19.0%) from Japan, and 390 (10.3%) from China. World publications grew with a sigmoid (logistic) pattern (predicted maximum of 586.8 articles per year, P < .001). The United States and China also had logistic and slowing growth (maximums of 111.0 and 48.1 articles per year, respectively; both P < .001). Growth was linear in Japan (growth of 3.0 articles per year, P < .001) and exponential and accelerating in Germany, Italy, South Korea, France, and the United Kingdom. The United States produced 187 (36.9%) review articles but only 52 (13.1%) clinical trials. Japan (75, 18.8%) and China (71, 17.8%) both produced more clinical trials than other countries. U.S. IO articles were less likely than general radiology articles to receive funding from government (12.5% vs 23.7%) and nongovernment (15.0% vs 17.0%) sources. Liver cancer articles constituted 2388 (62.8%) of all IO articles. IO research is slowing in the United States but growing elsewhere. Japan and China are leaders in clinical trial research. U.S. IO research receives less funding than does overall radiology research. IO research focuses primarily on liver cancer. © RSNA, 2010.

Provide a descriptive review of bear and human interactions in the United States. Descriptive review. The bear population in the United States includes the grizzly bear, the polar bear, and the black bear, including the glacier phase or blue bear. As the human population grew and remote or wilderness access improved, the bear population suffered both in total numbers and safe habitat. Conservation efforts, such as hunting restrictions and habitat enhancement, have helped to increase the total numbers of bears on the North American continent. The chance of a human encountering a bear increases as the remote bear territory diminishes. Bear incidents are widely publicized, though few serious incidents occur. The authors have direct knowledge of these bear-human encounters in Alaska. Serious human injuries from black bears, or maulings, including fatalities are uncommon. Grizzly bears when trapped or stimulated may be very dangerous. The polar bear sees everything that moves or has color, as potential food, and therefore, will attack seemingly unprovoked. The chance of a human encountering a bear increases as the remote bear territory diminishes. Bear incidents are widely publicized, though few serious incidents occur.

Evidence of underage targeting of alcohol advertising on television in the United States: lessons from the Lockyer v. Reynolds decisions.

Underage alcohol use is a global public health problem and alcohol advertising has been associated with underage drinking. The alcohol industry regulates itself and is the primary control on alcohol advertising in many countries around the world, advising trade association members to advertise only in adult-oriented media. Despite high levels of compliance with these self-regulatory guidelines, in several countries youth exposure to alcohol advertising on television has grown faster than adult exposure. In the United States, we found that exposure for underage viewers ages 18-20 grew from 2005 through 2011 faster than any adult age group. Applying a method adopted from a court in the US to identify underage targeting of advertising, we found evidence of targeting of alcohol advertising to underage viewers ages 18-20. The court's rule appeared in Lockyer v. Reynolds (The People ex rel. Bill Lockyer v. R.J. Reynolds Tobacco Company, GIC764118, 2002). We demonstrated that alcohol companies were able to modify their advertising practices to maintain current levels of adult advertising exposure while reducing youth exposure.

1991-12-01

During a 3-week period multiple blood cultures obtained from 14 Neonatal Intensive Care Unit infants and 3 Newborn Unit babies grew Candida guilliermondii, a yeast rarely associated with infections in humans. At the time of detection of positive cultures, most infants had been hospitalized for days or weeks for serious perinatal conditions and treated with antibiotics and intravenous hyperalimentation. Two critically ill premature infants from whom the yeast was isolated were given amphotericin B. In 7 other infants, however, yeasts were recovered on the day of birth, raising the question of pseudofungemia. Exhaustive interrogation on the blood culture practices revealed that when drawing blood for a culture from small infants, "butterfly" needles were often flushed with a diluted heparin solution to prevent blood clotting. Culture of a single lot of diluted heparin vials, prepared at the hospital pharmacy and distributed to the Neonatal Intensive Care Unit and Newborn Unit shortly before the onset of the epidemic, grew between 10,000 and 15,000 colony-forming units of Candida guilliermondii/ml. Removal of contaminated heparin vials and discontinuation of heparinization of needles used for blood cultures resulted in cessation of the epidemic. The present outbreak illustrates the difficulties in recognizing pseudoinfections in sick premature infants and the importance of intensive investigation and intervention during such an outbreak.

'These pushful days': time and disability in the age of eugenics.

PubMed

Baynton, Douglas C

2011-01-01

At the turn of the twentieth century, social attitudes toward disability turned sharply negative. An international eugenics movement brought about restrictive immigration laws in the United States and other immigrant nations. One cause was the changing understanding of time, both historical and quotidian, that accompanied the advent of evolutionary theory and a competitive industrial economy. As analogies of competition became culturally ubiquitous, new words to talk about disability such as 'handicapped', 'retarded', 'abnormal', 'degenerate', and 'defective', came into everyday use, all of them explicitly or implicitly rooted in new ways of thinking about time. The intense fear of disability that characterised the eugenics movement grew, in good part, from this new and unsettling vision of time.

State Policies Influence Medicare Telemedicine Utilization.

Neufeld, Jonathan D; Doarn, Charles R; Aly, Reem

2016-01-01

Medicare policy regarding telemedicine reimbursement has changed little since 2000. Many individual states, however, have added telemedicine reimbursement for either Medicaid and/or commercial payers over the same period. Because telemedicine programs must serve patients from all or most payers, it is likely that these state-level policy changes have significant impacts on telemedicine program viability and utilization of services from all payers, not just those services and payers affected directly by state policy. This report explores the impact of two significant state-level policy changes-one expanding Medicaid telemedicine coverage and the other introducing telemedicine parity for commercial payers-on Medicare utilization in the affected states. Medicare claims data from 2011-2013 were examined for states in the Great Lakes region. All valid claims for live interactive telemedicine professional fees were extracted and linked to their states of origin. Allowed encounters and expenditures were calculated in total and on a per 1,000 members per year basis to standardize against changes in the Medicare population by state and year. Medicare telemedicine encounters and professional fee expenditures grew sharply following changes in state Medicaid and commercial payer policy in the examined states. Medicare utilization in Illinois grew by 173% in 2012 (over 2011) following Medicaid coverage expansion, and Medicare utilization in Michigan grew by 118% in 2013 (over 2012) following adoption of telemedicine parity for commercial payers. By contrast, annual Medicare telemedicine utilization growth in surrounding states (in which there were no significant policy changes during these years) varied somewhat but showed no discernible pattern. Although Medicare telemedicine policy has changed little since its inception, changes in state policies with regard to telemedicine reimbursement appear to have significant impacts on the practical viability of telemedicine programs that bill Medicare for telemedicine services.

Developed nations share similar challenges to human health from commercial and agricultural chemicals that are released into the environment. Although Russia and the United States are historically distinct and unique, both countries are geographically large and economically dependent on emission-producing surface transportation. This paper describes U.S.-Russian collaborative activities that grew from a 1995 conference in Moscow that brought together environmental health investigators from both countries to discuss common concerns about the human health impact of environmental pollutants. Lead, pesticides, volatile organic compounds, and mercury were identified as contaminants of greatest concern. Collaborative studies were initiated that included collecting blood and hair samples and splitting samples for analyses in both countries, and introducing and sharing new portable blood and environmental sample analyses instruments. The findings demonstrated that hair analysis was not a good predictor of BLL and that Russian children in the first city sampled had a mean BLL of 7.7 microg/dl. Although higher than the U.S. mean, this level was below the 10.0 microg/dl CDC level of concern. This manuscript summarizes additional study results and describes their impacts on Russian policy. On-going collaborative environmental investigations are described.

Continued progress in implementing smoke-free laws throughout the United States would benefit from documenting positive economic effects, particularly for the hospitality industry. This study describes changes in sales revenue in bars and taverns since December 2005, when a statewide smoke-free law in Washington State went into effect. Using 24 quarters of inflation-adjusted taxable retail sales data from 2002 through 2007, we fitted a regression model to estimate the effect of the smoke-free law on sales revenue, controlling for seasonality and other economic factors. We found no immediate change in bar revenues in the first quarter of 2006, but taxable retail sales grew significantly through the fourth quarter of 2007. In the 2 years after the smoke-free law was implemented, sales revenues were $105.5 million higher than expected for bars and taverns in Washington State. The higher-than-expected revenue from taxable sales in bars and taverns after the implementation of smoke-free laws in Washington State provided extra funds to the state general fund. Potential increases in revenue in other jurisdictions that implement smoke-free indoor air policies could provide funds to benefit residents of those jurisdictions.

Identifying the environmental constraints that affect the distribution of an invasive species is fundamental to its effective control. Triadica sebifera (Chinese tallow tree) has invaded the southeastern United States, but its potential for further range and habitat extension has been unresolved. We explored experimentally environmental factors in macro- and microhabitats that affect its persistence at five widely separated sites along the Atlantic seaboard of the United States and at two sites inland; three sites occur well beyond the tree's current range. At each site, seeds and young vegetative plants (0.5-0.65 m tall) of T. sebifera were placed in four microhabitats (closed-canopy upland, closed-canopy lowland, open-canopy upland, and open-canopy lowland). Plant growth, leaf CO(2) assimilation rates, leaf N concentrations and delta(13)C ratios, and stem water potential were measured for two growing seasons. Percent seed germination was consistently higher in open-canopy microhabitats and lowest at northern and inland sites. T. sebifera grew in all open-canopy microhabitats, even 300-500 km beyond its current distribution. Plant growth in closed-canopy habitats was lower, attributable to lower carbon gain per unit leaf area in shaded compared with open-canopy environments, especially at northern and inland sites. Neither competition, other than canopy shade, nor grazing was a key constraint on distribution at any scale. Our results demonstrate that T. sebifera is dispersal limited at landscape scales but limited locally by dispersal and overstory shade; it has yet to occupy the full extent of its new range in North America. Quantifying environmental factors both within and well beyond a species' current range can effectively highlight the limits on its distribution.

On The Export Control Of High Speed Imaging For Nuclear Weapons Applications

Since the Manhattan Project, the use of high-speed photography, and its cousins flash radiography1 and schieleren photography have been a technological proliferation concern. Indeed, like the supercomputer, the development of high-speed photography as we now know it essentially grew out of the nuclear weapons program at Los Alamos2,3,4. Naturally, during the course of the last 75 years the technology associated with computers and cameras has been export controlled by the United States and others to prevent both proliferation among non-P5-nations and technological parity among potential adversaries among P5 nations.

The residential sector is one of the main end-use sectors in Canada accounting for 16.7% of total end-use site energy consumption in 2009 (computed from NRCan 2012. pp, 4-5). In this year, the residential sector accounted for 54.5% of buildings total site energy consumption. Between 1990 and 2009, Canadian household energy consumption grew by less than 11%. Nonetheless, households contributed to 14.6% of total energy-related greenhouse gas emissions in Canada in 2009 (computed from NRCan 2012). This is the U.S. Energy Information Administration’s second study to help provide a better understanding of the factors impacting residential energy consumption and intensity in North America (mainly the United States and Canada) by using similar methodology for analyses in both countries.

2011-01-01

In July 2002, lightning strikes started five forest fires that merged into one massive wildfire in the Klamath-Siskiyou Ecoregion of southern Oregon. Aided by drought, severe weather conditions, dry fuels, and steep topography, the fire grew to more than 200,000 hectares of mostly public forest land. Known as the Biscuit Fire, it was Oregon's largest forest fire in more than 130 years and one of the largest wildfires on record in the United States. Discussions centered around why such a massive fire was happening, how large would it become, who was keeping communities and homes safe, and what would be the final economic and ecological outcome. Weeks later when the fire was out, conversations turned to other questions, including what, if anything, should happen for forest recovery.

The development of the tubular membrane plant growth unit for the delivery of water and nutrients to roots in microgravity has recently focused on measuring the effects of changes in physical variables controlling solution availability to the plants. Significant effects of membrane pore size and the negative pressure used to contain the solution were demonstrated. Generally, wheat grew better in units with a larger pore size but equal negative pressure and in units with the same pore size but less negative pressure. Lettuce also exhibited better plant growth at less negative pressure.

Inequality as a basis for the U.S. emergence from the great stagnation.

PubMed

Chernomas, R

1999-01-01

A significant body of evidence suggests that capitalism entered an economic crisis phase in the late 1960s due to a fall in the rate of profit. With falling profits, corporations are compelled to find means of reducing costs by lowering wages and taxes and/or raising productivity. Attacks on the welfare state (in the form of the war on deficits and debts), unions, and government in general resulted in falling wages, longer hours of work, and increased poverty. Only in 1997, despite years of exaggeration about its macroeconomic recovery, did the United States finally have a true boom year, like something from the Golden Age of the 1950s or early 1960s: GDP, investment, productivity, employment, and even wages grew by reasonable historical standards. This article is an account of how this tentative recovery was accomplished--in part, by the state and corporate sectors' ability to generate inequality over the past quarter century--and how these changes in the macroeconomy changed the context for health and the health sector.

Plant resources and colony growth in an invasive ant: the importance of honeydew-producing Hemiptera in carbohydrate transfer across trophic levels.

PubMed

Helms, Ken R; Vinson, S Bradleigh

2008-04-01

Studies have suggested that plant-based nutritional resources are important in promoting high densities of omnivorous and invasive ants, but there have been no direct tests of the effects of these resources on colony productivity. We conducted an experiment designed to determine the relative importance of plants and honeydew-producing insects feeding on plants to the growth of colonies of the invasive ant Solenopsis invicta (Buren). We found that colonies of S. invicta grew substantially when they only had access to unlimited insect prey; however, colonies that also had access to plants colonized by honeydew-producing Hemiptera grew significantly and substantially ( approximately 50%) larger. Our experiment also showed that S. invicta was unable to acquire significant nutritional resources directly from the Hemiptera host plant but acquired them indirectly from honeydew. Honeydew alone is unlikely to be sufficient for colony growth, however, and both carbohydrates abundant in plants and proteins abundant in animals are likely to be necessary for optimal growth. Our experiment provides important insight into the effects of a common tritrophic interaction among an invasive mealybug, Antonina graminis (Maskell), an invasive host grass, Cynodon dactylon L. Pers., and S. invicta in the southeastern United States, suggesting that interactions among these species can be important in promoting extremely high population densities of S. invicta.

Fish of either sex that were irradiated as fry grew faster than controls at all test X-ray doses. Among fish irradiated at 7-8 weeks, males grew significantly faster, but females grew significantly slower, than controls at all test doses. X-ray-induced changes in growth were dose-dependent: growth rates of fry (both sexes) and of juvenile males rose relative to those of controlsmore » with increased radiation dose. The growth increase per unit of radiation dose was higher for fry than for older juveniles. The length-weight regression was steeper for irradiated males than for controls. The average weights of F{sub 1} offspring of irradiated fish were greatly reduced as compared with controls, which suggests the transfer of the detrimental effects of X rays from irradiated parents to their offspring. 39 refs., 3 figs., 3 tabs.« less

Integrating spirituality into patient care: an essential element of person‑centered care.

Puchalski, Christina M

2013-01-01

Spirituality and health is a growing field of healthcare. It grew out of courses in spirituality and health developed for medical students in the United States. Research in this area over the last 30 years has also formed an evidence base for spirituality and health. Studies have demonstrated an association between spiritual beliefs and values and a variety of healthcare outcomes. More recent research has also shown a strong desire on the part of patients to have their spirituality addressed as part of their care. Studies also show that spiritual care has an impact on patient decision making, particularly in end-of-life care. The Association of American Medical Colleges developed a broad definition of spirituality as well as learning objectives and guidelines for teaching. Standards in organizations such as the American College of Physicians support physicians treating the whole person, that is, the body, mind, and spirit. In 2009, National Competencies in Spirituality and Health education were developed in the United States with schools currently working on curriculum projects based on these competencies. Models are being developed for all members of the healthcare team to address patient distress, in cooperation with chaplains as spiritual care experts. The goals are to develop a biopsychosocial and spiritual assessment and treatment as part of compassionate whole-person care of all patients.

Dance is a popular activity associated with many physical and mental health benefits, but injuries are a concern for all skill levels. Previous studies have focused on professional dancers or particular genres, meaning the population-wide characteristics of injuries is unknown. This study's objective was to identify the incidence and types of dance-related injuries evaluated in emergency departments in the United States over the 14-year period 2000-2013. Data were obtained from the nationally representative National Electronic Injury Surveillance System from 2000-2013. National estimates of injuries were determined using complex sample design. Trends using 2-year intervals were calculated using linear regression and injury proportion ratios using Pearson's X2. The average annual incidence of dance-related injuries requiring emergency medical attention was 17,145 per year. The number of injuries grew from 14,204 in 2000/1 to 21,356 in 2012/3, a change of 33.4% after accounting for population growth. Lower limb injuries were most common, particularly ankle and knee sprains. Females presented with a greater proportion of ankle (injury proportion ratio [IPR]=1.34, p=0.029) and foot sprains (IPR=2.11, p<0.001) but a lower proportion of shoulder sprains (IPR=0.41, p<0.001) and face lacerations (IPR=0.13, p<0.001). Younger dancers presented with a lower proportion of knee (IPR=0.79, p=0.006) and low back sprains (IPR=0.68, p=0.019). The average annual incidence of dance-related injuries of a serious enough nature to require presentation to the emergency department in the United States was 17,145 per year, with ankle and knee sprains being the most common. Injury numbers have increased in recent years.

Deaths to babies in their first 28 days of life now account for more than 40% of global under-5 child mortality. High neonatal mortality poses a significant barrier to achieving the child survival Millennium Development Goal. Surmounting the problem requires national-level political commitment, yet only a few nation-states have prioritised this issue. We compare Bolivia, Malawi and Nepal, three low-income countries with high neonatal mortality, with a view to understanding why countries prioritise or neglect the issue. The three have had markedly different trajectories since 2000: attention grew steadily in Nepal, stagnated then grew in Malawi and grew then stagnated in Bolivia. The comparison suggests three implications for proponents seeking to advance attention to neglected health issues in low-income countries: the value of (1) advancing solutions with demonstrated efficacy in low-resource settings, (2) building on existing and emerging national priorities and (3) developing a strong network of domestic and international allies. Such actions help policy communities to weather political storms and take advantage of policy windows.

2017-03-01

Between the early 1900s and the 1990s, the greater snow goose Anser caerulescens atlanticus population grew from 3000 individuals to more than 700 000. Because of concerns about Arctic degradation of natural habitats through overgrazing, a working group recommended the stabilization of the population. Declared overabundant in 1998, special management actions were then implemented in Canada and the United States. Meanwhile, a cost-benefit socioeconomic analysis was performed to set a target population size. Discussions aiming towards attaining a common vision were undertaken with stakeholders at multiple levels. The implemented measures have had varying success; but population size has been generally stable since 1999. To be effective and meet social acceptance, management actions must have a scientific basis, result from a consensus among stakeholders, and include an efficient monitoring programme. In this paper, historical changes in population size and management decisions along with past and current challenges encountered are discussed.

A young Marshallese woman presented with the insidious development of fever, cough, fatigue, profound weakness, massive weight loss, cachexia, alopecia, amenorrhea, and periumbilical hyperpigmentation. Limited laboratory studies revealed anemia, leukocytosis, and hyponatremia. Imaging studies, as well as digital photographs, transmitted over the Internet, using the secure Pacific Island Health Care Project (PIHCP), store-and-forward telemedicine system, suggested the diagnosis of disseminated tuberculosis, and antimycobacterial antibiotics were begun. Sputum cultures eventually grew Mycobacterium tuberculosis. Based on the constellation of clinical signs and symptoms, the transmitted images, and limited laboratory data, adrenal tuberculosis (Addison's disease) with adrenal insufficiency was diagnosed and corticosteroids were initiated. The patient responded dramatically This case underscores the utility of telemedicine in the diagnosis and treatment of patients with unusual conditions, rarely seen today in the United States, from remote sites in the Developing World.

Explaining the Widening Education Gap in Mortality among U.S. White Women

Montez, Jennifer Karas; Zajacova, Anna

2013-01-01

Over the last half century the gap in mortality across education levels grew in the United States, and since the mid-1980s the growth was especially pronounced among white women. The reasons for the growth among white women are unclear. We investigated three explanations—social-psychological factors, economic circumstances, and health behaviors—for the widening education gap in mortality across 1997-2006 among white women 45-84 years of age. We used data from the National Health Interview Survey Linked Mortality File (N=46,744; deaths=4,053). We found little support for social-psychological factors; however, economic circumstances and health behaviors jointly explained the growing education gap in mortality to statistical nonsignificance. Employment and smoking were the most important individual components. Increasing high school graduation rates, reducing smoking prevalence, and designing work-family policies that help women find and maintain desirable employment may reduce mortality inequalities among women.

The fundamental objectives of the capstone design project in the Department of Astronautics at the United States Air Force Academy (USAFA) are for cadets to learn important engineering lessons by executing a real space mission on a Department of Defense-funded satellite project. FalconSAT-3 is a 50 kg, gravity gradient-stabilized designed and built by cadets and launched March 2007 on the first ESPA (Enhanced extended launch vehicle Satellite Payload Adapter) mission. FalconSAT-3 was one of six satellites integrated onto the launch vehicle and the nature of the mission made it that the satellite was subject to the full formality of testing requirements. Two successive gravity gradient booms failed either design requirements or environmental testing; design requirements grew dramatically during the design phase; ambiguous thermal vacuum test results led to uncertainty at launch; and after launch it was not possible to contact the satellite for several weeks.

“The Priest Obviously Doesn’t Know That I’m Gay”: The Religious and Spiritual Journeys of Latino Gay Men

García, Dalia I.; Gray-Stanley, Jennifer; Ramirez-Valles, Jesus

2013-01-01

In the United States, most adults state that religion plays an important role in their lives and claim a religious affiliation. For gay, bisexual, and transgender persons (GBT), the story is unique because their sexual and gender identity is not accepted by most religions. The purpose of this article is to analyze the role of religiosity in the life course of Latino GBTs raised as Catholics. Data come from 66 life history interviews with Latino GBTs living in Chicago and San Francisco, who grew up as Catholics. We found a religious trajectory that mirrored participants’ developmental stages. During childhood, religion was inculcated by the family, culture, and schools. In adolescence, many experienced a conflict between their religion and their GBT identity, and in adulthood, they reached a resolution. Most participants abandoned Catholicism to join other religions or spiritual groups that they perceived to be welcoming. We found participants engaging in a remedial ideological work to reconcile their religious values and their identity. PMID:19042279

Characterization of coke, or carbonaceous matter, formed on CoMo catalysts used in hydrodesulfurization unit in oil refinery

NASA Astrophysics Data System (ADS)

Kimura, Nobuharu; Iwanami, Yoshimu; Koide, Ryutaro; Kudo, Reiko

2017-06-01

When a mixture of light gas oil (LGO) and light cycle oil is fed into an oil refinery’s hydrodesulfurization (HDS) unit to produce diesel fuel, the catalyst in the HDS unit is rapidly deactivated. By contrast, when the feed is LGO mixed with residue desulfurization gas oil, the catalyst is deactivated slowly. Hoping to understand why, the authors focused on the coke formed on the catalysts during the HDS reaction. The result of a comprehensive analysis of the coke suggested that the ways coke formed and grew on the catalysts may differ depending on the feeds used, which in turn could affect the deactivation behaviors of the catalysts.

Adaptation of plastic surfaces for tissue culture by glow discharge.

1975-01-01

Plastic petri dishes and microtitration plates were electrically charged by a glow discharge unit installed in a vacuum evaporator. Charged and uncharged plates, as well as plates commercially treated for tissue culture, were inoculated with Vero and BHK-21 cell lines; secondary cultures of monkey kidney, chicken lung, canine kidney, and embryonic bovine kidney; and primary chicken embryo fibroblasts and chicken lung cells. All cell cultures grew normally on petri plates charged with the covers open. Growth rate and cell density compared favorably with growth on the commercial tissue culture plates; cell growth was somewhat less dense, however, on plates charged with the covers closed. Charged plates could be sterilized by ultraviolet light and ethylene oxide with no adverse effects on cell growth. Cells inoculated onto plates charged up to 7 months before inoculation grew as well as on freshly charged plates. Images PMID:818106

Manuel, C M; Nunes, O C; Melo, L F

2007-02-01

Drinking water biofilm formation on polyvinyl chloride (PVC), cross-linked polyethylene (PEX), high density polyethylene (HDPE) and polypropylene (PP) was followed in three different reactors operating under stagnant or continuous flow regimes. After one week, a quasi-steady state was achieved where biofilm total cell numbers per unit surface area were not affected by fluctuations in the concentration of suspended cells. Metabolically active cells in biofilms were around 17-35% of the total cells and 6-18% were able to form colony units in R(2)A medium. Microbiological analysis showed that the adhesion material and reactor design did not affect significantly the biofilm growth. However, operating under continuous flow (0.8-1.9 Pa) or stagnant water had a significant effect on biofilm formation: in stagnant waters, biofilm grew to a less extent. By applying mass balances and an asymptotic biofilm formation model to data from biofilms grown on PVC and HDPE surfaces under turbulent flow, specific growth rates of bacteria in the biofilm were found to be similar for both materials (around 0.15 day(-1)) and much lower than the specific growth rates of suspended bacteria (around 1.8 day(-1)).

Spore prevalence and toxigenicity of Bacillus cereus and Bacillus thuringiensis isolates from U.S. retail spices.

Hariram, Upasana; Labbé, Ronald

2015-03-01

Recent incidents of foodborne illness associated with spices as the vehicle of transmission prompted this examination of U.S. retail spices with regard to Bacillus cereus. This study focused on the levels of aerobic-mesophilic spore-forming bacteria and B cereus spores associated with 247 retail spices purchased from five states in the United States. Samples contained a wide range of aerobic-mesophilic bacterial spore counts (< 200 to 8.3 × 10(7) CFU/g), with 19.1% of samples at levels above 10(5) CFU/g. For examples, paprika, allspice, peppercorns, and mixed spices had high levels of aerobic spores (> 10(7) CFU/g). Using a novel chromogenic agar, B. cereus and B. thuringiensis spores were isolated from 77 (31%) and 11 (4%) samples, respectively. Levels of B. cereus were <3 to 1,600 MPN/g. Eighty-eight percent of B. cereus isolates and 91% of B. thuringiensis isolates possessed at least one type of enterotoxin gene: HBL (hemolysin BL) or nonhemolytic enterotoxin (NHE). None of the 88 isolates obtained in this study possessed the emetic toxin gene (ces). Using commercially available immunological toxin detection kits, the toxigenicity of the isolates was confirmed. The NHE enterotoxin was expressed in 98% of B. cereus and 91% of B. thuringiensis isolates that possessed the responsible gene. HBL enterotoxin was detected in 87% of B. cereus and 100% of B. thuringiensis PCR-positive isolates. Fifty-two percent of B. cereus and 54% of B. thuringiensis isolates produced both enterotoxins. Ninety-seven percent of B. cereus isolates grew at 12°C, although only two isolates grew well at 9°C. The ability of these spice isolates to form spores, produce diarrheal toxins, and grow at moderately abusive temperatures makes retail spices an important potential vehicle for foodborne illness caused by B. cereus strains, in particular those that produce diarrheal toxins.

Growth of Escherichia coli O157:H7, Non-O157 Shiga Toxin-Producing Escherichia coli , and Salmonella in Water and Hydroponic Fertilizer Solutions.

The desire for local, fresh produce year round is driving the growth of hydroponic growing systems in the United States. Many food crops, such as leafy greens and culinary herbs, grown within hydroponics systems have their root systems submerged in recirculating nutrient-dense fertilizer solutions from planting through harvest. If a foodborne pathogen were introduced into this water system, the risk of contamination to the entire crop would be high. Hence, this study was designed to determine whether Escherichia coli O157:H7, non-O157 Shiga toxin-producing E. coli , and Salmonella were able to survive and reproduce in two common hydroponic fertilizer solutions and in water or whether the bacteria would be killed or suppressed by the fertilizer solutions. All the pathogens grew by 1 to 6 log CFU/ml over a 24-h period, depending on the solution. E. coli O157:H7 reached higher levels in the fertilizer solution with plants (3.12 log CFU/ml), whereas non-O157 Shiga toxin-producing E. coli and Salmonella reached higher levels in the fertilizer solution without plants (1.36 to 3.77 log CFU/ml). The foodborne pathogens evaluated here survived for 24 h in the fertilizer solution, and populations grew more rapidly in these solutions than in plain water. Therefore, human pathogens entering the fertilizer solution tanks in hydroponic systems would be expected to rapidly propagate and spread throughout the system and potentially contaminate the entire crop.

How has funding to developing countries for health improvement changed in the wake of the global financial crisis? The question is vital for policy making, planning, and advocacy purposes in donor and recipient countries alike. We measured the total amount of financial and in-kind assistance that flowed from both public and private channels to improve health in developing countries during the period 1990-2011. The data for the years 1990-2009 reflect disbursements, while the numbers for 2010 and 2011 are preliminary estimates. Development assistance for health continued to grow in 2011, but the rate of growth was low. We estimate that assistance for health grew by 4 percent each year from 2009 to 2011, reaching a total of $27.73 billion. This growth was largely driven by the World Bank's International Bank for Reconstruction and Development and appeared to be a deliberate strategy in response to the global economic crisis. Assistance for health from bilateral agencies grew by only 4 percent, or $444.08 million, largely because the United States slowed its development assistance for health. Health funding through UN agencies stagnated, and the Global Fund to Fight AIDS, Tuberculosis, and Malaria announced that it would make no new grants for the next two years because of declines in funding. Given the international community's focus on meeting the Millennium Development Goals by 2015 and persistent economic hardship in donor countries, continued measurement of development assistance for health is essential for policy making.

Patients in an intensive care unit (ICU) are frequently immunocompromised and might be highly susceptible to infection. Visitors to an ICU who do not adequately clean their hands could carry pathogenic organisms, resulting in risk to a vulnerable patient population. This observational study identifies pathogens carried on the hands of visitors into an ICU and investigates the effect of hand hygiene. Two observers, one stationed outside and one inside the ICU, evaluated whether visitors performed hand hygiene at any of the wall-mounted alcohol-based hand sanitizer dispensers prior to reaching a patient's room. Upon reaching a patient's room, the dominant hand of all of the participants was cultured. Of the 55 participating visitors, 35 did not disinfect their hands. Among the cultures of those who failed to perform hand hygiene, eight cultures grew Gram-negative rods and one grew methicillin-resistant Staphylococcus aureus. Of the cultures of the 20 individuals who performed hand hygiene, 14 (70%) had no growth on the cultures, and the remaining six (30%) showed only the usual skin flora. The visitors who do not perform hand hygiene might carry pathogens that pose a risk to ICU patients. Copyright © 2015 King Saud Bin Abdulaziz University for Health Sciences.

The effects of soil flooding on the establishment of cogongrass (Imperata cylindrica), a nonindigenous invader of the southeastern United States

King, S.E.; Grace, J.B.

2000-01-01

Cogongrass (Imperata cylindrica), an invasive perennial introduced from Southeast Asia, is currently spreading throughout the southeastern United States from Florida to Louisiana. In the U.S., cogongrass is generally not considered a wetland species, although it's range is expanding in regions with high wetland abundance. The objective of this study was to determine if excessive soil moisture might prevent cogongrass from establishing in areas with seasonally flooded soils. In one greenhouse experiment, we examined cogongrass germination and seedling growth in soils that were freely drained, saturated, and inundated. We performed a second greenhouse experiment to evaluate growth and survival of cogongrass seedlings of four different size classes in five soil moisture treatments ranging from dry to inundated. Cogongrass germination was lowest when seeds were overtopped with water. There were no differences in germination between saturated and freely drained treatments; however, seedlings grew largest in freely drained soil and were smallest when immersed. In our second experiment, most cogongrass plants survived except when given no water, but growth differed by watering treatment depending on seedling size. Increasing moisture was more detrimental to the growth of small seedlings compared to the growth of larger cogongrass plants. Overall, cogongrass was most sensitive to soil inundation in the earliest stages of establishment; thus, excessive moisture conditions in the spring, during early seedling development, could restrict invasion of cogongrass by seed. Once cogongrass is established, however, its tolerance of flooding appears to increase.

Numerous species have been introduced to Coeur d'Alene Lake, Idaho over the last century, but minimal research has been completed to understand their population dynamics. The objective of this study was to describe the population demographics and dynamics of northern pike (Esox lucius) and smallmouth bass (Micropterus dolomieu), two important nonnative sport fishes in the system to provide information that will assist with guiding management decisions. The oldest northern pike was age 7 and the oldest smallmouth bass was age 11. Populations of both species exhibited very stable recruitment with a recruitment coefficient of determination of 0.99 for northern pike and 0.98 for smallmouth bass. Total annual mortality was estimated as 66% for northern pike and 42% for smallmouth bass. Growth of northern pike in Coeur d'Alene Lake was comparable to the 50–75th percentiles of growth exhibited by lentic northern pike populations across North America. Northern pike in Coeur d'Alene Lake were most similar to populations in the north-central and northeast United States with fast growth rates and short life spans. In contrast, smallmouth bass grew slowly and generally fell within the 5th percentile of lentic smallmouth bass populations in North America. Smallmouth bass in Coeur d'Alene Lake were similar to other populations in northern regions of the United States displaying slow growth rates with high longevity. Results of this study provide important insight on nonnative northern pike and smallmouth bass population dynamics.

The growing market for electronic cigarettes (e-cigarettes) has been widely reported in the media, but very little objective data exist in the scientific literature, and no data have been published on state-specific trends in prices or sales. Our objective is to assess state-specific annual sales and average prices for e-cigarettes in the U.S. Commercial retail scanner data were used to assess total dollar sales and average price per unit for disposable e-cigarettes, starter kits, and cartridge refills for selected states and the total U.S. during 2012-2013. Data were analyzed in 2014. Data were available for convenience stores (29 states) and food, drug, and mass merchandisers (44 states). In convenience stores, dollar sales increased markedly during 2012-2013: 320.8% for disposable e-cigarettes, 72.4% for starter kits, and 82% for cartridges. In food, drug, and mass merchandisers, dollar sales increased 49.5% for disposable e-cigarettes, 89.4% for starter kits, and 126.2% for cartridges. Average prices across all product categories increased in convenience stores and decreased in food, drug, and mass merchandisers. Sales and prices varied substantially across states included in the analyses. Sales of all e-cigarette device types grew considerably in convenience stores and food, drug, and mass merchandisers during 2012-2013. The market for e-cigarettes is growing rapidly, resulting in dynamic sales and price changes that vary across the U.S. Continued state-specific surveillance of the e-cigarette market is warranted.

This article describes the U.S. Geological Survey (USGS) 2018 one‐year probabilistic seismic hazard forecast for the central and eastern United States from induced and natural earthquakes. For consistency, the updated 2018 forecast is developed using the same probabilistic seismicity‐based methodology as applied in the two previous forecasts. Rates of earthquakes across the United States M≥3.0">M≥3.0 grew rapidly between 2008 and 2015 but have steadily declined over the past 3 years, especially in areas of Oklahoma and southern Kansas where fluid injection has decreased. The seismicity pattern in 2017 was complex with earthquakes more spatially dispersed than in the previous years. Some areas of west‐central Oklahoma experienced increased activity rates where industrial activity increased. Earthquake rates in Oklahoma (429 earthquakes of M≥3">M≥3 and 4 M≥4">M≥4), Raton basin (Colorado/New Mexico border, six earthquakes M≥3">M≥3), and the New Madrid seismic zone (11 earthquakes M≥3">M≥3) continue to be higher than historical levels. Almost all of these earthquakes occurred within the highest hazard regions of the 2017 forecast. Even though rates declined over the past 3 years, the short‐term hazard for damaging ground shaking across much of Oklahoma remains at high levels due to continuing high rates of smaller earthquakes that are still hundreds of times higher than at any time in the state’s history. Fine details and variability between the 2016–2018 forecasts are obscured by significant uncertainties in the input model. These short‐term hazard levels are similar to active regions in California. During 2017, M≥3">M≥3 earthquakes also occurred in or near Ohio, West Virginia, Missouri, Kentucky, Tennessee, Arkansas, Illinois, Oklahoma, Kansas, Colorado, New Mexico, Utah, and Wyoming.

The number of African immigrants in the United States grew 40-fold between 1960 and 2007, from 35 355 to 1.4 million, with a large majority from West Africa. This study sought to examine the prevalence of cardiovascular disease (CVD) risk factors and global CVD risk and to identify independent predictors of increased CVD risk among West African immigrants in the United States. This cross-sectional study assessed West African (Ghanaian and Nigerian) immigrants aged 35-74 years in the Baltimore-Washington metropolitan area. The mean age of participants was 49.5±9.2 years, and 58% were female. The majority (95%) had ≥1 of the 6 CVD risk factors. Smoking was least prevalent, and overweight or obesity was most prevalent, with 88% having a body mass index (in kg/m(2)) ≥25; 16% had a prior diagnosis of diabetes or had fasting blood glucose levels ≥126 mg/dL. In addition, 44% were physically inactive. Among women, employment and health insurance were associated with odds of 0.09 (95% CI 0.033-0.29) and 0.25 (95% CI 0.09-0.67), respectively, of having a Pooled Cohort Equations estimate ≥7.5% in the multivariable logistic regression analysis. Among men, higher social support was associated with 0.90 (95% CI 0.83-0.98) lower odds of having ≥3 CVD risk factors but not with having a Pooled Cohort Equations estimate ≥7.5%. The prevalence of CVD risk factors among West African immigrants was particularly high. Being employed and having health insurance were associated with lower CVD risk in women, but only higher social support was associated with lower CVD risk in men. © 2016 The Authors.

Social Class and Income Inequality in the United States: Ownership, Authority, and Personal Income Distribution from 1980 to 2010

PubMed Central

Wodtke, Geoffrey T.

2016-01-01

This study outlines a theory of social class based on workplace ownership and authority relations, and it investigates the link between social class and growth in personal income inequality since the 1980s. Inequality trends are governed by changes in between-class income differences, changes in the relative size of different classes, and changes in within-class income dispersion. Data from the General Social Survey are used to investigate each of these changes in turn and to evaluate their impact on growth in inequality at the population level. Results indicate that between-class income differences grew by about 60 percent since the 1980s and that the relative size of different classes remained fairly stable. A formal decomposition analysis indicates that changes in the relative size of different social classes had a small dampening effect and that growth in between-class income differences had a large inflationary effect on trends in personal income inequality.

Private enrollments and expenditure on education: Some macro trends

NASA Astrophysics Data System (ADS)

Tan, Jee-Peng

1985-12-01

Many less-developed countries (LDCs) are today facing difficulties in the financing of education. On the one hand, state budgetary allocations to the sector are already very high, and appear likely to grow only slowly, if at all. At the same time, however, the demand for education is rising, not least because of demographic pressures. Without changes in the system, both to reduce unit costs through improving efficiency and to mobilize additional resources for the sector, the level of educational development, particularly in the poorest LDCs, is likely to remain low. Coupled with the stagnation in public spending on education, the data suggest that total national spending in the sector has tended to decline as GDP grew. This trend should perhaps be discouraged since education contributes significantly to economic development. One way of doing so is to increase the share of private participation in total spending in the sector, for example, by increasing the role of private education, especially where it is weak and declining over time.

Utilizing a stable isotopic time series obtained from a speleothem (PC-1), which grew between 20.1 and 15.6 ka, Lachniet, Asmeron and Polyak (2011; hereafter LAP) present evidence for a significant cold event in the southern Great Basin at 18.6 ka, a finding that we accept. Supplementing this short record with a literature review, they go on to claim, as their central thesis, that the paleoclimate of the southwestern US was driven by “the transmission of atmospheric anomalies to the southwest…that coincided with deglacial climate changes in Greenland and the North Atlantic region”, not by a “dominant Pacific Ocean SST control” as suggested by SST time series off California and by the Devils Hole δ18O time series from the southern Great Basin. We do not find their central thesis supportable.

Retail clinics have rapidly become a fixture of the United States health care delivery landscape. In our analyses of trends in retail clinic utilization, we find there has been a four-fold increase in retail clinic visits between 2007 to 2009, with an estimated 5.9 million retail clinic visits in 2009. Compared with the period from 2000–2006, in the period from 2007–9 retail clinic patients are now more likely to be greater than 65 years old (18.9 percent vs. 7.8 percent) and preventive care, in particular the influenza vaccine, has become a larger component of their care (47.5 percent vs. 21.8 percent of visits). Across all retail clinic visits, 44.4 percent are on the weekend or on the weekdays when physician offices are typically closed. Retail clinics appear to be meeting a need for convenient care, in particular during times when physician offices are not open. PMID:22895454

Diverging Mobility Trajectories: Grandparent Effects on Educational Attainment in One- and Two-Parent Families in the United States.

PubMed

Song, Xi

2016-12-01

In recent years, sociological research investigating grandparent effects in three-generation social mobility has proliferated, mostly focusing on the question of whether grandparents have a direct effect on their grandchildren's social attainment. This study hypothesizes that prior research has overlooked family structure as an important factor that moderates grandparents' direct effects. Capitalizing on a counterfactual causal framework and multigenerational data from the Panel Study of Income Dynamics, this study examines the direct effect of grandparents' years of education on grandchildren's years of educational attainment and heterogeneity in the effects associated with family structure. The results show that for both African Americans and whites, grandparent effects are the strongest for grandchildren who grew up in two-parent families, followed by those in single-parent families with divorced parents. The weakest effects were marked in single-parent families with unmarried parents. These findings suggest that the increasing diversity of family forms has led to diverging social mobility trajectories for families across generations.

To examine variables influencing the positive health practices (PHP) of Filipino college students to gain a better understanding of health practices in this ethnic/racial group. Cross-sectional study tested theoretical relationships postulated among (a) PHP, (b) social support (SS), (c) optimism, and (d) acculturation. A sample of Filipino college students (N = 226) aged 18 to 21 was obtained in June 2009. Participants completed 4 instruments. Statistical analyses were performed using SPSS 16.0. Positive correlations were found between PHP and SS (r = .39, p = .01) and optimism and PHP (r = .36, p = .01). No correlation was found between PHP and acculturation. Optimism and SS predicted performance of PHP (R (2) = .18, F[2, 221] = 24.927, p < .001). A difference was found in acculturation levels between participants who grew up in the United States (t[223] = 4.5, p < .001) and those who did not. Findings help health practitioners and educators to better understand the underlying factors that influence PHP in this population.

Origins of the Human Genome Project

DOE R&D Accomplishments Database

Cook-Deegan, Robert (Affiliation: Institute of Medicine, National Academy of Sciences)

1993-07-01

The human genome project was borne of technology, grew into a science bureaucracy in the United States and throughout the world, and is now being transformed into a hybrid academic and commercial enterprise. The next phase of the project promises to veer more sharply toward commercial application, harnessing both the technical prowess of molecular biology and the rapidly growing body of knowledge about DNA structure to the pursuit of practical benefits. Faith that the systematic analysis of DNA structure will prove to be a powerful research tool underlies the rationale behind the genome project. The notion that most genetic information is embedded in the sequence of CNA base pairs comprising chromosomes is a central tenet. A rough analogy is to liken an organism's genetic code to computer code. The coal of the genome project, in this parlance, is to identify and catalog 75,000 or more files (genes) in the software that directs construction of a self-modifying and self-replicating system -- a living organism.

Student nurses' attitudes and beliefs about breast-feeding.

2006-01-01

This study explored the breast-feeding attitudes and beliefs of students newly enrolled in an urban university baccalaureate nursing program. A qualitative approach was used to conduct in-depth semistructured interviews with 12 students prior to their formal course work in maternal-child nursing. Four themes emerged from the data analysis: 1. Personal experiences are important in the development of breast-feeding attitudes and beliefs. 2. The students generally believed that breast-feeding offered benefits for babies and mothers, but the beliefs were stronger for those who grew up with breast-feeding as the norm. 3. All the students believed that there were barriers to breast-feeding in the United States that they identified as the societal view of the breast, dependence/independence conflicts, and concerns about intimacy. 4. The students identified an educational rather than promotional role for nurses in breast-feeding because of conflicts about personal choice. This study suggests that students need help identifying their attitudes and beliefs about breast-feeding and reflecting how their personal experiences influence breast-feeding promotion.

2012-01-01

Background Studies of tobacco use and other health behaviors have reported great challenges in recruiting young adults. Social media is widely used by young adults in the United States and represents a potentially fast, affordable method of recruiting study participants for survey research. Objective The present study examined Facebook as a mechanism to reach and survey young adults about tobacco and other substance use. Methods Participants were cigarette users, age 18-25 years old, living throughout the United States and recruited through Facebook to complete a survey about tobacco and other substance use. Paid advertising using Facebook’s Ad program over 13 months from 2010 Feb 28 to 2011 Apr 4 targeted by age (18-25), location (United States or California), language (English), and tobacco- and/or marijuana-related keywords. Facebook approved all ads. Results The campaign used 20 ads, which generated 28,683,151 impressions, yielding 14,808 clicks (0.7% of targeted Facebook members), at an overall cost of $6,628.24. The average cost per click on an ad was $0.45. The success of individual ads varied widely. There was a rise in both clicks and impressions as the campaign grew. However, the peak for clicks was 3 months before the peak for ad impressions. Of the 69,937,080 accounts for those age 18-25 in the United States, Facebook estimated that 2.8% (n = 1,980,240) were reached through tobacco and marijuana keywords. Our campaign yielded 5237 signed consents (35.4% of clicks), of which 3093 (59%) met criteria, and 1548 (50% of those who met criteria) completed the survey. The final cost per valid completed survey was $4.28. The majority of completed surveys came from whites (69%) and males (72%). The sample averaged 8.9 cigarettes per day (SD 7.5), 3.8 years of smoking (SD 2.9), with a median of 1 lifetime quit attempts; 48% did not intend to quit smoking in the next 6 months. Conclusions Despite wide variety in the success of individual ads and potential concerns about sample representativeness, Facebook was a useful, cost-effective recruitment source for young-adult smokers to complete a survey about the use of tobacco and other substances. The current findings support Facebook as a viable recruitment option for assessment of health behavior in young adults. PMID:22360969

The potential of vancomycin-resistant enterococci to persist in fermented and pasteurised meat products.

Houben, J H

2003-11-15

Experiments with 148 isolates of vancomycin-resistant enterococci (VRE) were performed to assess their potential to persist and grow in fermented sausages and pasteurised meat products. All strains were meat isolates and Van-type A, except a single VanC1 strain. In total, 143 strains of Enterococcus faecium were involved. Eight selected strains were examined for their potential to grow at high salt and nitrite levels and at reduced pH. The same isolates were used in experiments with fermented sausages. All available strains were subjected to heating tests in meat suspensions with added curing ingredients. All but one of the eight tested isolates grew at pH 4.0 in tryptone soya broth (TSB). With the combination of 8% w/w NaCl, 400 ppm NaNO2 and 0.5% w/w glucose in the meat suspension, all isolates grew at 37 degrees C, whereas none grew at 7 degrees C even after 56 days. With the addition of 10% w/w NaCl, 200 ppm NaNO2 and 0.5% w/w glucose, still one E. faecium isolate grew at 37 degrees C, although very slowly. Overall, the strains tolerated high salt and nitrite concentrations and reduced pH very well, even beyond levels applied in the regular production of fermented and/or pasteurised meat products. The tested strains could be isolated after the fermentation and further ripening of "boerenmetworst" and "snijworst". Overall, their colony counts decreased on average about 1 log-unit over a period of 60 days after batter manufacture. All 148 isolates demonstrated a relatively weak thermal resistance compared to results for selected vancomycin-sensitive enterococci strains reported in the literature and to results collected under identical experimental conditions in this laboratory. None of the strains (log inoculation level about 5-6 ml(-1) for each isolate) could be cultured after heating at 70 degrees C for 10 min.

Drivers of healthcare expenditures associated with physician services.

PubMed

Koenig, Lane; Siegel, Jonathan M; Dobson, Allen; Hearle, Keith; Ho, Silver; Rudowitz, Robin

2003-06-01

To identify and rank the key contributors to increases in healthcare costs for physician services. We performed regression analysis using state-level physician cost data from the state health expenditure accounts maintained by the Centers for Medicare and Medicaid Services (CMS) and a national, private (commercial) health insurer. We estimated that during 1990 to 2000, nominal physician expenditures per capita grew 4.7% annually. Forty-two percent of this growth was attributable to general price inflation measured by the gross domestic product price deflator. The category of general economic variables and demographics was the next largest contributor to growth at 17%, followed by physician supply and provider structure (12%) and technology and treatment patterns (11%). Operating costs, health status, healthcare regulation, and health insurance benefit and product design comprised the remaining 18% of the growth. Because physicians are central to the healthcare system in the United States, efforts to contain physician spending reverberate through all healthcare services. The combined effect of an increase in the number and proportion of specialty care physicians, the continued development of clinical approaches for the control of chronic disease, and an aging population requiring intensive medical care imply that the current increase in healthcare expenditures could continue unabated, unless effective cost-control devices are deployed. To be effective, emerging strategies for influencing the affordability of healthcare services are likely to require a greater level of partnership between payers, providers, and other stakeholders.

GROWING UP WITHOUT SIBLINGS AND ADULT SOCIABILITY BEHAVIORS

PubMed Central

Trent, Katherine; Spitze, Glenna D.

2011-01-01

We use data from the National Survey of Families and Households to examine a range of sociability behaviors for adults who grew up with and without siblings. Compared to adults who grew up with siblings, adults who grew up without siblings have less frequent social activities with relatives, and the difference is greater among those who did not live with both parents growing up. Differences in engaging in certain social events between adults who grew up without and with siblings vary by age. Differences in participation in sports, youth, or school related group activities for those who grew up without and with siblings vary by gender. Thus, there are some differences in adult sociability behaviors between those who grew up with and without siblings; however, our pattern of findings suggests that these differences are not large or pervasive across a range of sociability behaviors and may grow smaller with age.

Fleming, Charles B.; Guttmannova, Katarina; Cambron, Christopher; Rhew, Isaac C.; Oesterle, Sabrina

2016-01-01

Purpose As marijuana laws have become more permissive, survey data on adolescents in the United States have shown an increase in marijuana-specific risk factors, particularly in the proportion of youth who do not perceive marijuana use as harmful. Prevalence of marijuana use among youth, however, has changed little. Using representative data from Washington State, which has legalized medical and nonmedical marijuana for adults, we examined two competing hypotheses to account for this divergence in population trends. Methods Data were from 2000 – 2014 biennial Washington State surveys of 10th-grade students. First, we assessed whether associations between marijuana use and marijuana-specific risk factors have weakened over time. Second, we examined whether decreases in alcohol and cigarette use can account for the lack of expected increase in marijuana use prevalence. Results Despite stability in marijuana use prevalence, there were increases in marijuana-specific risk factors of low perceived harm, youth favorable attitudes about use, and perceived community attitudes favorable to use. Associations between marijuana use and marijuana-use predictors varied little across time; if anything, the positive association between low perceived harm and marijuana use grew stronger. Decreases in prevalence of alcohol and cigarette use largely accounted for stability in marijuana use during a period when marijuana risk factors increased. Conclusions Decreases in other types of substance use or in the underlying, common risk for substance use may have mitigated effects of increases in marijuana-specific risk factors. PMID:27318426

Navigating Without Road Maps: The Early Business of Automobile Route Guide Publishing in the United States

NASA Astrophysics Data System (ADS)

Bauer, John T.

2018-05-01

In the United States, automobile route guides were important precursors to the road maps that Americans are familiar with today. Listing turn-by-turn directions between cities, they helped drivers navigate unmarked, local roads. This paper examines the early business of route guide publishing through the Official Automobile Blue Book series of guides. It focuses specifically on the expansion, contraction, and eventual decline of the Blue Book publishing empire and also the work of professional "pathfinders" that formed the company's data-gathering infrastructure. Be- ginning in 1901 with only one volume, the series steadily grew until 1920, when thirteen volumes were required to record thousands of routes throughout the country. Bankruptcy and corporate restructuring in 1921 forced the publishers to condense the guide into a four-volume set in 1922. Competition from emerging sheet maps, along with the nationwide standardization of highway numbers, pushed a switch to an atlas format in 1926. Blue Books, however, could not remain competitive and disappeared after 1937. "Pathfinders" were employed by the publishers and equipped with reliable automobiles. Soon they developed a shorthand notation system for recording field notes and efficiently incorporating them into the development workflow. Although pathfinders did not call themselves cartographers, they were geographical data field collectors and considered their work to be an "art and a science," much the same as modern-day cartographers. The paper concludes with some comments about the place of route guides in the history of American commercial cartography and draws some parallels between "pathfinders" and the digital road mappers of today.

Straight talk about high-fructose corn syrup: what it is and what it ain't.

White, John S

2008-12-01

High-fructose corn syrup (HFCS) is a fructose-glucose liquid sweetener alternative to sucrose (common table sugar) first introduced to the food and beverage industry in the 1970s. It is not meaningfully different in composition or metabolism from other fructose-glucose sweeteners like sucrose, honey, and fruit juice concentrates. HFCS was widely embraced by food formulators, and its use grew between the mid-1970s and mid-1990s, principally as a replacement for sucrose. This was primarily because of its sweetness comparable with that of sucrose, improved stability and functionality, and ease of use. Although HFCS use today is nearly equivalent to sucrose use in the United States, we live in a decidedly sucrose-sweetened world: >90% of the nutritive sweetener used worldwide is sucrose. Here I review the history, composition, availability, and characteristics of HFCS in a factual manner to clarify common misunderstandings that have been a source of confusion to health professionals and the general public alike. In particular, I evaluate the strength of the popular hypothesis that HFCS is uniquely responsible for obesity. Although examples of pure fructose causing metabolic upset at high concentrations abound, especially when fed as the sole carbohydrate source, there is no evidence that the common fructose-glucose sweeteners do the same. Thus, studies using extreme carbohydrate diets may be useful for probing biochemical pathways, but they have no relevance to the human diet or to current consumption. I conclude that the HFCS-obesity hypothesis is supported neither in the United States nor worldwide.

Strategic larval decision-making in a bivoltine butterfly.

In temperate areas, insect larvae must decide between entering winter diapause or developing directly and reproducing in the same season. Long daylength and high temperature promote direct development, which is generally associated with a higher growth rate. In this work, we investigated whether the larval pathway decision precedes the adjustment of growth rate (state-independent), or whether the pathway decision is conditional on the individual's growth rate (state-dependent), in the butterfly Pieris napi. This species typically makes the pathway decision in the penultimate instar. We measured growth rate throughout larval development under two daylengths: slightly shorter and slightly longer than the critical daylength. Results indicate that the pathway decision can be both state-independent and state-dependent; under the shorter daylength condition, most larvae entered diapause, and direct development was chosen exclusively by a small subset of larvae showing the highest growth rates already in the early instars; under the longer daylength condition, most larvae developed directly, and the diapause pathway was chosen exclusively by a small subset of slow-growing individuals. Among the remainder, the choice of pathway was independent of the early growth rate; larvae entering diapause under the short daylength grew as fast as or faster than the direct developers under the longer daylength in the early instars, whereas the direct developers grew faster than the diapausers only in the ultimate instar. Hence, the pathway decision was state-dependent in a subset with a very high or very low growth rate, whereas the decision was state-independent in the majority of the larvae, which made the growth rate adjustment downstream from the pathway decision.

It has been thought that the first cities in the Near East were spatially extensive and grew outward from a core nucleated village while maintaining a more or less constant density in terms of persons or households per unit of area. The general applicability outside of the Near East of this southern Mesopotamian.derived model has been questioned recently, and variations from it are increasingly recognized. We can now demonstrate that such variation was present at the beginnings of urbanism in the Near East as well.

Growing Super-Dwarf wheat in Space Station Mir

Salisbury, F. B.

1997-01-01

Super-Dwarf wheat plants were grown in the Russian/Bulgarian growth chamber called Svet (means light in Russian), in Space Station Mir, from August 12 to November 9, 1995 (90 days) and from August 5 to December 6, 1996 (123 days); a second 1996 crop grew from December 6, 1996 to January 14, 1997 (39 days). Environmental monitoring instrumentation was built at Utah State University and added to Svet for the experiments. That instrumentation functioned well in 1995, but four of six lamp sets (two lamps in each set) failed, as did the controller and a fan. Plants stayed alive but were mostly vegetative (contrary to ground controls under equivalent photon flux). New, higher intensity lamps and other equipment functioned well during 1996, and plants grew surprisingly well, producing about 280 heads and considerable biomass, but the heads were all sterile. A strong case can be made that the sterility was caused by high ethylene in the cabin atmosphere.

A Personal Perspective on Triangle Universities Nuclear Laboratory Development

NASA Astrophysics Data System (ADS)

Clegg, Thomas B.

2011-10-01

Nuclear physics research in NC began seriously in 1950 when Henry Newson and his colleagues at Duke attracted support for a 4 MeV Van de Graaff accelerator with which they grew their doctoral training program. The lab's scientific achievements also grew, including the discovery in 1966 of fine structure of nuclear analog states. By then UNC and NC State had attracted Eugen Merzbacher and Worth Seagondollar who, with Newson, brought more faculty to work at an enlarged three-university, cooperative lab. Launched at Duke in 1967 with a 30 MeV Cyclograff accelerator, and subsequently equipped with a polarized H and D ion source and polarized H and ^3He targets, an extensive program in light-ion and neutron physics ensued. Faculty interest in electromagnetic interactions led to development since 2001 of TUNL's HIγS facility to produce intense 1-100 MeV polarized photon beams with small energy spread. Photonuclear reaction studies there today are producing results of unmatched quality. These 60 years of nuclear physics research have produced ˜250 doctoral graduates, many of whom have gone on to very distinguished careers. A personal perspective on these activities will be presented.

"Talkin' about a revolution": How electronic health records can facilitate the scale-up of HIV care and treatment and catalyze primary care in resource-constrained settings.

Health care for patients with HIV infection in developing countries has increased substantially in response to major international funding. Scaling up treatment programs requires timely data on the type, quantity, and quality of care being provided. Increasingly, such programs are turning to electronic health records (EHRs) to provide these data. We describe how a medical school in the United States and another in Kenya collaborated to develop and implement an EHR in a large HIV/AIDS care program in western Kenya. These data were used to manage patients, providers, and the program itself as it grew to encompass 18 sites serving more than 90,000 patients. Lessons learned have been applicable beyond HIV/AIDS to include primary care, chronic disease management, and community-based health screening and disease prevention programs. EHRs will be key to providing the highest possible quality of care for the funds developing countries can commit to health care. Public, private, and academic partnerships can facilitate the development and implementation of EHRs in resource-constrained settings.

Extracorporeal membrane oxygenation (ECMO) has been increasingly studied as a life support modality, but it is unclear if its use has changed over time. Recent publication shows no significant trend in use of ECMO over time; however, this report does not include more recent data. We performed trend analysis to determine if and when the use of ECMO changed in the past decade. We identified hospitalizations (2000-2011) in the Nationwide Inpatient Sample during which ECMO was recorded. We used a segmented linear regression model to determine trend and to identify a temporal change point when rate of ECMO use increased. ECMO use gradually grew until 2007, at which time there was a dramatic increase in the rate (p = 0.0003). There was no difference in mortality after 2007 (p = 0.3374), but there was longer length of stay (p = 0.0001) and smaller percentage of women (p = 0.005). There has been a marked increase in ECMO use since 2007. As ECMO use becomes more common, further study regarding indications, cost-effectiveness, and outcomes is warranted to guide optimal use.

Analysis of capital spending and capital financing among large US nonprofit health systems.

PubMed

Stewart, Louis J

2012-01-01

This article examines the recent trends (2006 to 2009) in capital spending among 25 of the largest nonprofit health systems in the United States and analyzes the financing sources that these large nonprofit health care systems used to fund their capital spending. Total capital spending for these 25 nonprofit health entities exceeded $41 billion for the four-year period of this study. Less than 3 percent of total capital spending resulted in mergers and acquisition activities. Total annual capital spending grew at an average annual rate of 17.6 percent during the first three year of this study's period of analysis. Annual capital spending for 2009 fell by more than 22 percent over prior year's level due to the impact of widespread disruption in US tax-exempt variable rate debt markets. While cash inflow from long-term debt issues was a significant source of capital financing, this study's primary finding was that operating cash flow was the predominant source of capital spending funding. Key words: nonprofit, mergers and acquisitions (M&A), capital spending, capital financing.

Farming the Desert: agriculture in the World War II-era Japanese-American relocation centers.

PubMed

Lillquist, Karl

2010-01-01

In 1942 over 110,000 Japanese Americans were evacuated from the West Coast to ten inland, barbed wire-enclosed relocation centers in the name of national security. Agriculture was a key component of the eight arid to semi-arid centers located in the western United States. Each center's agricultural program included produce for human consumption, feed crops, and livestock. Some centers also grew seed, ornamental, and war crops. Evacuees raised and consumed five types of livestock and sixty-one produce varieties, including many traditional foods. Seasonal surpluses were preserved, shipped to other centers, or sold on the open market. Short growing seasons, poor soils, initially undeveloped lands, pests, equipment shortages, and labor issues hampered operations. However, imprisoned evacuee farmers proved that diverse agricultural programs could succeed in the harsh settings primarily because of labor-intensive farming methods, ingenuity, and the large markets provided by the centers. These agricultural programs played major roles in feeding, providing meaningful employment, and preparing evacuees for life outside the centers, and readied lands for post-war "homesteaders."

Beller Lecture: The Roots of Leo Szilard and his Interdisciplinarity

NASA Astrophysics Data System (ADS)

Marx, George

1998-04-01

A Central European among the whites was said about Leo Szilard who originated from a polycultural family. In the early 20th century he grew up in Hungary, at the crossroads of history, where political regimes, national borders, ideological doctrines, ``final truths'' changed in a dizzying cavalcade. Instead of conservative dogmatism this social environment required critical thinking in order to survive. World War I was the school of Theodore von Kármán, John von Neumann, Eugene P. Wigner and Leo Szilard; each of them learned trespassing political and disciplinary boundaries without inhibition. Their sensitivity for trends had been utilized by the United States when war efforts and high tech required orientation under new horizons. Szilard's interest ranged from statistical physics through information theory to biological evolution, from life phenomena through hot atoms to nuclear strategy. His intellectual adventures might look crazy jumps for specialists. But now, looking back to the political and technological history of the 20th century one can see than it was a consequent progress of a future-sensitive mind.

In three nationally representative surveys of U.S. residents (N = 10 million) from 1970 to 2015, more Americans in the early 2010s (vs. previous decades) identified as Independent, including when age effects were controlled. More in the early 2010s (vs. previous decades) expressed polarized political views, including stronger political party affiliation or more extreme ideological self-categorization (liberal vs. conservative) with fewer identifying as moderate. The correlation between party affiliation and ideological views grew stronger over time. The overall trend since the 1970s was toward more Americans identifying as Republican or conservative. Older adults were more likely to identify as conservative and Republican. More Millennials (born 1980-1994) identify as conservative than either GenXers or Boomers did at the same age, and fewer are Democrats compared with Boomers. These trends are discussed in the context of social identification processes and their implications for the political dynamics in the United States. © 2016 by the Society for Personality and Social Psychology, Inc.

Incised channel fills containing conifers indicate that seasonally dry vegetation dominated Pennsylvanian tropical lowlands

The idea that the Pennsylvanian tropical lowlands were temporally dominated by rainforest (i.e., the Coal Forest) is deeply ingrained in the literature. Here we challenge two centuries of research by suggesting that this concept is based on a taphonomic artifact, and that seasonally dry vegetation dominated instead. This controversial finding arises from the discovery of a new middle Pennsylvanian (Moscovian) fossil plant assemblage in southeast Illinois, United States. The assemblage, which contains xerophytic walchian conifers, occurs in channels incised into a calcic Vertisol below the Baker Coal. These plants grew on seasonally dry tropical lowlands inferred to have developed during a glacial phase. This xerophytic flora differs markedly from that of the typical clubmoss-dominated Coal Forest developed during deglaciation events. Although preserved only very rarely, we argue that such xerophytic floras were temporally as dominant, and perhaps more dominant, than the iconic Coal Forests, which are overrepresented in the fossil record due to taphonomic megabias. These findings require the iconography of Pennsylvanian tropical lowlands to be redrawn. ?? 2009 Geological Society of America.

Preemptive biopreparedness: can we learn anything from history?

PubMed Central

Fee, E; Brown, T M

2001-01-01

The treat of bioterrorism is in the public eye again, and major public health agencies are urging preparedness efforts and special federal funding. In a sense, we have seen this all before. The Centers for Disease Control and Prevention grew substantially during the Cold War era in large part because Alexander Langmuir, Chief Epidemiologist of the CDC, used an earlier generation's anxieties to revitalize the CDC, create an Epidemic Intelligence Service, and promote epidemiologic "surveillance" as part of the nation's defense. Retrospective investigation suggests that, while Langmuir contributed to efforts promoted by the Department of Defense and the Federal Civil Defense Administration, the United States did not have real cause to fear Communist biological warfare aggression. Given clear historical parallels, it is appropriate to ask, What was gained and what was lost by Langmuir's central role in that first instance of American biopreparedness? Among the conclusions drawn is that biopreparedness efforts fed the Cold War climate, narrowed the scope of public health activities, and failed to achieve sustained benefits for public health programs across the country.

Lignocellulose degradation during solid-state fermentation: Pleurotus ostreatus versus Phanerochaete chrysosporium

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

Kerem, Z.; Friesem, D.; Hadar, Y.

Lignocellulose degradation and activities related to lignin degradation were studied in the solid-state fermentation of cotton stalks by comparison two white rot fungi, Pleurotus ostreatus and Phanerochaete chrysosporium. P. chrysosporium grew vigorously, resulting in rapid, nonselective degradation of 55% of the organic components of the cotton stalks within 15 days. In contrast, P. ostreatus grew more slowly with obvious selectivity for lignin degradation and resulting in the degradation of only 20% of the organic matter after 30 days of incubation. The kinetics of {sup 14}C-lignin mineralization exhibited similar differences. In cultures of P. chrysosporium, mineralization ceased after 18 days, resultingmore » in the release of 12% of the total radioactivity as {sup 14}CO{sub 2}. In P. ostreatus, on the other hand, 17% of the total radioactivity was released in a steady rate throughout a period of 60 days of incubation. Laccase activity was only detected in water extracts of the P. ostreatus fermentation. No lignin peroxidase activity was detected in either the water extract or liquid cultures of this fungus. 2-Keto-4-thiomethyl butyric acid cleavage to ethylene correlated to lignin degradation in both fungi. A study of fungal activity under solid-state conditions, in contrast to those done under defined liquid culture, may help to better understand the mechanism involved in lignocellulose degradation.« less

The objective of this study is to estimate the annual costs of information, education, and communication (IEC), both community- and school-based; strengthened public and private sexually transmitted infections treatment; condom social marketing (CSM); and voluntary counseling and testing (VCT) implemented in Masaka, Uganda, over 4 years, and to explore how unit costs change with varying population use/uptake. Total economic provider's costs and intervention outputs were collected annually to estimate annual unit costs between 1996 and 1999. In early intervention years, uptake of all activities grew dramatically and continued to grow for public STI treatment, CSM, and VCT. Attendance at IEC performances started to drop in year 4. Unit costs dropped rapidly with increasing uptake of and participation in interventions. When implementing long-term community-based interventions, it is important to take into account that it takes time for communities to scale up their participation, since this can lead to large variations in unit costs.

The United States government has operated Dobson ozone spectrophotometers at various sites, starting during the International Geophysical Year (1 July 1957 to 31 December 1958). A network of stations for long-term monitoring of the total column content (thickness of the ozone layer) of the atmosphere was established in the early 1960s and eventually grew to 16 stations, 14 of which are still operational and submit data to the United States of America's National Oceanic and Atmospheric Administration (NOAA). Seven of these sites are also part of the Network for the Detection of Atmospheric Composition Change (NDACC), an organization that maintains its own data archive. Due to recent changes in data processing software the entire dataset was re-evaluated for possible changes. To evaluate and minimize potential changes caused by the new processing software, the reprocessed data record was compared to the original data record archived in the World Ozone and UV Data Center (WOUDC) in Toronto, Canada. The history of the observations at the individual stations, the instruments used for the NOAA network monitoring at the station, the method for reducing zenith-sky observations to total ozone, and calibration procedures were re-evaluated using data quality control tools built into the new software. At the completion of the evaluation, the new datasets are to be published as an update to the WOUDC and NDACC archives, and the entire dataset is to be made available to the scientific community. The procedure for reprocessing Dobson data and the results of the reanalysis on the archived record are presented in this paper. A summary of historical changes to 14 station records is also provided.

To analyze overall trends of elective cervical spine surgery in the United States from 2003 to 2013 with the goal of determining whether the economic downturn had an impact. Codes from the International Classification of Diseases, Ninth Revision, Clinical Modification were used to identify elective cervical spine surgery procedures in the Nationwide Inpatient Sample from 2003 to 2013. National Health Expenditure, gross domestic product, and S&P 500 Index were used as measures of economic performance. The economic downturn was defined as 2008-2009. Confidence intervals were determined using subgroup analysis techniques. Linear regressions were completed to determine the association between surgery trends and economic conditions. From 2003 to 2013, posterior cervical fusions saw a 102.7% increase. During the same time frame, there was a 7.4% and 14.7% decrease in the number of anterior cervical diskectomy and fusions (ACDFs) and posterior decompressions, respectively. The trend of elective cervical spine surgeries per 100,000 persons in the U.S. population may have been affected by the economic downturn from 2008 to 2009 (-0.03% growth). The percentage of procedures paid for by private insurance decreased from 2003 to 2013 for all ACDFs, posterior cervical fusions, and posterior decompressions. The linear regression coefficients (β) and R 2 values between the number of surgeries and each of the macroeconomic factors analyzed were not statistically significant. The overall elective cervical spine surgery trend was not likely impacted by the economic downturn. Posterior cervical fusions grew significantly from 2003 to 2013, whereas ACDFs and posterior decompressions decreased. Copyright © 2016 Elsevier Inc. All rights reserved.

Recent trends in the probability of high out-of-pocket medical expenses in the United States

PubMed Central

Baird, Katherine E

2016-01-01

Objective: This article measures the probability that out-of-pocket expenses in the United States exceed a threshold share of income. It calculates this probability separately by individuals’ health condition, income, and elderly status and estimates changes occurring in these probabilities between 2010 and 2013. Data and Method: This article uses nationally representative household survey data on 344,000 individuals. Logistic regressions estimate the probabilities that out-of-pocket expenses exceed 5% and alternatively 10% of income in the two study years. These probabilities are calculated for individuals based on their income, health status, and elderly status. Results: Despite favorable changes in both health policy and the economy, large numbers of Americans continue to be exposed to high out-of-pocket expenditures. For instance, the results indicate that in 2013 over a quarter of nonelderly low-income citizens in poor health spent 10% or more of their income on out-of-pocket expenses, and over 40% of this group spent more than 5%. Moreover, for Americans as a whole, the probability of spending in excess of 5% of income on out-of-pocket costs increased by 1.4 percentage points between 2010 and 2013, with the largest increases occurring among low-income Americans; the probability of Americans spending more than 10% of income grew from 9.3% to 9.6%, with the largest increases also occurring among the poor. Conclusion: The magnitude of out-of-pocket’s financial burden and the most recent upward trends in it underscore a need to develop good measures of the degree to which health care policy exposes individuals to financial risk, and to closely monitor the Affordable Care Act’s success in reducing Americans’ exposure to large medical bills.

Quasi-static time-series simulation using OpenDSS in IEEE distribution feeder model with high PV penetration and its impact on solar forecasting

NASA Astrophysics Data System (ADS)

Mohammed, Touseef Ahmed Faisal

Since 2000, renewable electricity installations in the United States (excluding hydropower) have more than tripled. Renewable electricity has grown at a compounded annual average of nearly 14% per year from 2000-2010. Wind, Concentrated Solar Power (CSP) and solar Photo Voltaic (PV) are the fastest growing renewable energy sectors. In 2010 in the U.S., solar PV grew over 71% and CSP grew by 18% from the previous year. Globally renewable electricity installations have more than quadrupled from 2000-2010. Solar PV generation grew by a factor of more than 28 between 2000 and 2010. The amount of CSP and solar PV installations are increasing on the distribution grid. These PV installations transmit electrical current from the load centers to the generating stations. But the transmission and distribution grid have been designed for uni-directional flow of electrical energy from generating stations to load centers. This causes imbalances in voltage and switchgear of the electrical circuitry. With the continuous rise in PV installations, analysis of voltage profile and penetration levels remain an active area of research. Standard distributed photovoltaic (PV) generators represented in simulation studies do not reflect the exact location and variability properties such as distance between interconnection points to substations, voltage regulators, solar irradiance and other environmental factors. Quasi-Static simulations assist in peak load planning hour and day ahead as it gives a time sequence analysis to help in generation allocation. Simulation models can be daily, hourly or yearly depending on duty cycle and dynamics of the system. High penetration of PV into the power grid changes the voltage profile and power flow dynamically in the distribution circuits due to the inherent variability of PV. There are a number of modeling and simulations tools available for the study of such high penetration PV scenarios. This thesis will specifically utilize OpenDSS, a open source Distribution System Simulator developed by Electric Power Research Institute, to simulate grid voltage profile with a large scale PV system under quasi-static time series considering variations of PV output in seconds, minutes, and the average daily load variations. A 13 bus IEEE distribution feeder model is utilized with distributed residential and commercial scale PV at different buses for simulation studies. Time series simulations are discussed for various modes of operation considering dynamic PV penetration at different time periods in a day. In addition, this thesis demonstrates simulations taking into account the presence of moving cloud for solar forecasting studies.

2,3-Diketo-5-methylthiopentyl-1-phosphate enolase (DK-MTP-1P enolase) from Bacillus subtilis was crystallized using the hanging-drop vapour-diffusion method. Crystals grew using PEG 3350 as the precipitant at 293 K. The crystals diffracted to 2.3 Å resolution at 100 K using synchrotron radiation and were found to belong to the monoclinic space group P21, with unit-cell parameters a = 79.3, b = 91.5, c = 107.0 Å, β = 90.8°. The asymmetric unit contained four molecules of DK-MTP-1P enolase, with a V M value of 2.2 Å3 Da−1 and a solvent content of 43%. PMID:19194007

Data Insight: Health care spending in the U.S. grew 7.7% in 2003, down from 9.3% in 2002, marking the first decline in costs in seven years, according to a report by the Centers for Medicare & Medicaid Services Office of the Actuary. CMS economists say spending declined because state Medicaid programs cut budgets and became more efficient through the use of managed care.

A Polymer Visualization System with Accurate Heating and Cooling Control and High-Speed Imaging

A visualization system to observe crystal and bubble formation in polymers under high temperature and pressure has been developed. Using this system, polymer can be subjected to a programmable thermal treatment to simulate the process in high pressure differential scanning calorimetry (HPDSC). With a high-temperature/high-pressure view-cell unit, this system enables in situ observation of crystal formation in semi-crystalline polymers to complement thermal analyses with HPDSC. The high-speed recording capability of the camera not only allows detailed recording of crystal formation, it also enables in situ capture of plastic foaming processes with a high temporal resolution. To demonstrate the system’s capability, crystal formation and foaming processes of polypropylene/carbon dioxide systems were examined. It was observed that crystals nucleated and grew into spherulites, and they grew at faster rates as temperature decreased. This observation agrees with the crystallinity measurement obtained with the HPDSC. Cell nucleation first occurred at crystals’ boundaries due to CO2 exclusion from crystal growth fronts. Subsequently, cells were nucleated around the existing ones due to tensile stresses generated in the constrained amorphous regions between networks of crystals. PMID:25915031

Reaction rims of dolomite (CaMg[CO3]2) were produced by solid-state reactions at the contacts of oriented calcite (CaCO3) and magnesite (MgCO3) single crystals at 400 MPa pressure, 750-850 °C temperature, and 3-146 h annealing time to determine the reaction kinetics. The dolomite reaction rims show two different microstructural domains. Elongated palisades of dolomite grew perpendicular into the MgCO3 interface with length ranging from about 6 to 41 µm. At the same time, a 5-71 µm wide rim of equiaxed granular dolomite grew at the contact with CaCO3. Platinum markers showed that the original interface is located at the boundary between the granular and palisade-forming dolomite. In addition to dolomite, a 12-80 µm thick magnesio-calcite layer formed between the dolomite reaction rims and the calcite single crystals. All reaction products show at least an axiotactic crystallographic relationship with respect to calcite reactant, while full topotaxy to calcite prevails within the granular dolomite and magnesio-calcite. Dolomite grains frequently exhibit growth twins characterized by a rotation of 180° around one of the equivalent axis. From mass balance considerations, it is inferred that the reaction rim of dolomite grew by counter diffusion of MgO and CaO. Assuming an Arrhenius-type temperature dependence, activation energies for diffusion of CaO and MgO are E a (CaO) = 192 ± 54 kJ/mol and E a (MgO) = 198 ± 44 kJ/mol, respectively.

Promoting the health of Europeans in a rapidly changing world: a historical study of the implementation of World Health Organisation policies by the Nursing and Midwifery Unit, European Regional Office, 1970-2003 The World Health Organisation (WHO) was inaugurated in 1948. Formed in a period of post-war devastation, WHO aimed to develop and meet goals that would rebuild the health of shattered populations. The historical study reported here examined the work of the Nursing and Midwifery Unit (NMU) of WHO's European Regional Office during the later part of the twentieth century. The study examined archive sources lodged at the NMU archive. The sources included manuscripts relating to important NMU initiatives, reports and papers published by WHO, and a range of secondary sources. The study identified three main driving forces in the work of the NMU of the European Regional Office of WHO. One of the strongest of these was a drive to develop and promote the nursing profession within the countries of the European Region. The second was the promulgation and implementation of the positive public health strategies of WHO, particularly its '38 Targets for Health for All by the Year 2000'. The third focussed on securing equity across the European continent and on promoting the development of the nursing professions in poorer and less-developed countries. The study concludes that the nursing professions in European states grew in strength and influence, and that the health of populations improved throughout the continent between 1970 and 2003. It discusses the extent to which the role of the NMU in these advances may have been significant. © 2011 Blackwell Publishing Ltd.

Among 100 outpatient women with symptoms and signs of pelvic inflammatory disease and 200 asymptomatic, postpartum women, the prevalence rates of Neisseria gonorrhoeae were 19% and 9%, respectively. Of 46 women hospitalized for PID, 33% were culture-negative, 22% grew Enterobacteriaceae, 20% grew streptococci, 15% grew gonococci, and 15% grew anaerobes from blood, pus, or abscesses. One third of 67 women hospitalized for puerperal sepsis (PPS) were culture-negative; the bacteria isolated most frequently from the uterus, blood, urine, and pus were Enterobacteriaceae (36%), gonococci (28%), streptococci (25%), and anaerobes (4%). The low frequency of isolation of anaerobes in women with PID and PPS was due largely to limitations placed on the collection and processing of specimens for anaerobic bacteriology.

Globalization of Stem Cell Science: An Examination of Current and Past Collaborative Research Networks

Science and engineering research has becoming an increasingly international phenomenon. Traditional bibliometric studies have not captured the evolution of collaborative partnerships between countries, particularly in emerging technologies such as stem cell science, in which an immense amount of investment has been made in the past decade. Analyzing over 2,800 articles from the top journals that include stem cell research in their publications, this study demonstrates the globalization of stem cell science. From 2000 to 2010, international collaborations increased from 20.9% to 36% of all stem cell publications analyzed. The United States remains the most prolific and the most dominant country in the field in terms of publications in high impact journals. But Asian countries, particularly China are steadily gaining ground. Exhibiting the largest relative growth, the percent of Chinese-authored stem cell papers grew more than ten-fold, while the percent of Chinese-authored international papers increased over seven times from 2000 to 2010. And while the percent of total stem cell publications exhibited modest growth for European countries, the percent of international publications increased more substantially, particularly in the United Kingdom. Overall, the data indicated that traditional networks of collaboration extant in 2000 still predominate in stem cell science. Although more nations are becoming involved in international collaborations and undertaking stem cell research, many of these efforts, with the exception of those in certain Asian countries, have yet to translate into publications in high impact journals.

To study the most important metrics of publication in the field of reproductive medicine over the decade 2003-2012 to aid in discerning the clinical, social, and epidemiologic implications of this relatively new but rapidly emerging area in medical sciences. Bibliometric analysis of most-cited publications from Web of Science databases. Not applicable. None. None. Most productive and frequently cited investigators, institutions, and countries and specific areas of research, scientific collaborations, and comparison of the growth of reproductive medicine research compared with other areas of medical investigation such as obstetrics and gynecology and related science categories. We found that 90 investigators with more than 1,000 citations had jointly published 4,010 articles. A continued rise in the impact factor of reproductive medicine journals was seen. The number of publications in reproductive medicine grew more rapidly compared with other science categories. Presently 22% of highly cited articles in reproductive medicine research are published in journals belonging to science categories outside reproductive medicine. The most-cited study groups are situated in the Netherlands, Belgium, Spain, the United States, and the United Kingdom, and collaborative studies have been increasing. Reproductive medicine research and subsequent clinical development have attained scientific growth and maturity. High-quality research is increasingly being published in high-impact journals. The increase in (inter)national collaborations seems to be key to the field's success. Copyright © 2015 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

Strach-Sonsalla, Mareike; Stammler, Matthias; Wenske, Jan

In 1991, the Vindeby Offshore Wind Farm, the first offshore wind farm in the world, started feeding electricity to the grid off the coast of Lolland, Denmark. Since then, offshore wind energy has developed from this early experiment to a multibillion dollar market and an important pillar of worldwide renewable energy production. Unit sizes grew from 450 kW at Vindeby to the 7.5 MW-class offshore wind turbines (OWT ) that are currently (by October 2014) in the prototyping phase. This chapter gives an overview of the state of the art in offshore wind turbine (OWT) technology and introduces the principlesmore » of modeling and simulating an OWT. The OWT components -- including the rotor, nacelle, support structure, control system, and power electronics -- are introduced, and current technological challenges are presented. The OWT system dynamics and the environment (wind and ocean waves) are described from the perspective of OWT modelers and designers. Finally, an outlook on future technology is provided. The descriptions in this chapter are focused on a single OWT -- more precisely, a horizontal-axis wind turbine -- as a dynamic system. Offshore wind farms and wind farm effects are not described in detail in this chapter, but an introduction and further references are given.« less

Irene Kaminka Fischer, a prominent geodesist whose career spanned the years 1952-1977, died on 22 October 2009 at the age of 102 at an assisted living facility in Brighton, Mass. Born in Vienna, Austria, on 27 July 1907, Irene grew up there; graduating with a degree in mathematics from the Vienna Institute of Technology; and met and married her husband, Eric, a noted geographer. In 1939, the Fischers fled Nazi Austria, first to Palestine, and by 1941 had relocated to the United States. During the next 11 years, Irene worked at various jobs, as well as playing the role of mother to her son and daughter. But when her daughter was ready for college, she began to look for a position that would fully utilize her considerable talents in mathematics. She found a perfect fit at her husband's federal agency, the U.S. Army Map Service (AMS). Her entire career in geodesy was spent with that organization and its successors (currently the National Geospatial-Intelligence Agency (NGA)). Hired as a mathematician, she eventually was promoted to chief of the Geoid Branch in the Geodesy Division. She retained that position until her retirement in 1977.

Giant salvinia (Salvinia molesta Mitchell) is a non-native, invasive aquatic fern that was recently introduced to the southern United States. The aggressive nature of the species has led to concerns over its potential adverse impacts to native plants, fish, and invertebrates. We conducted a study to determine the efficacy of glyphosate [isopropylamine salt of N-(phosphono-methyl)glycine] and several surfactants for control of giant salvinia. Studies were conducted over a 42-day period using static renewals (twice weekly) with 4% Hoagland's medium (10 mg/L N equivalent) in replicated 2-L containers. Five concentrations of glyphosate (0, 0.45, 0.91, 1.82, and 3.60% v:v) and five surfactants (0.25% concentration, v:v; Optima???, Kinetic???, Mon 0818???, Cygnet Plus???, and LI-700???) were applied with a pressurized sprayer as a single surface application in a fully nested experimental design. Untreated giant salvinia grew rapidly and exhibited an increase of 800% wet weight biomass over the 42-day test duration. Glyphosate, with and without surfactants, exhibited efficacy at concentrations as low as 0.45% of the commercial formulation. Glyphosate with Optima was the only mixture that resulted in complete mortality of plants with no regrowth.

Third-Party Finance for Commercial Photovoltaic Systems: The Rise of the PPA

Installations of grid-connected photovoltaic (PV) systems in the United States have increased dramatically in recent years, growing from less than 20 MW in 2000 to nearly 500 MW at the end of 2007, a compound average annual growth rate of 59%. Of particular note is the increasing contribution of 'non-residential' grid-connected PV systems--defined here as those systems installed on the customer (rather than utility) side of the meter at commercial, institutional, non-profit, or governmental properties--to the overall growth trend. Although there is some uncertainty in the numbers, non-residential PV capacity grew from less than half of aggregate annual capacity installationsmore » in 2000-2002 to nearly two-thirds in 2007. This relative growth trend is expected to have continued through 2008. This article, which is excerpted from a longer report, focuses specifically on just one subset of the non-residential PV market: systems hosted (and perhaps owned) by commercial, tax-paying entities. Tax-exempt entities (e.g., non-profits or municipalities) face unique issues and have different financing options at their disposal; readers interested in PV financing options for tax-exempt entities can find more information in the Bolinger report.« less

Nineteenth Century Harbors: Accounting for Coastal Urban Development in Hydrologic Change

Harbors complicate the analytical framework of quantifying nineteenth-century hydrologic change in the northeastern United States. The hydrology of the region was fundamentally altered by the growth of water engineering such as canals as well as by land cover changes as deforestation in the region peaked and urban centers grew. Urban coastal growth epitomized nineteenth-century development as northeastern colonial ports evolved into manufacturing and industrial centers. Coastal urban industrial development concentrated tanneries, machineries, and paper processing companies along cities’ trading rivers. Additionally, the populations of cities such as Boston, New Haven, New York, Newark, and Baltimore reached unprecedented numbers, forcing urban municipalities to confront sewerage and drinking water infrastructure in the face of shortages and waterborne disease. We discuss how the concentration of industry and population at river mouths complicates the process of quantifying the effects of municipal drinking water and sewage infrastructure on regional hydrology and how the growth of nineteenth-century urban centers shaped regional hydrologic hinterlands. Additionally, harbors oblige a reconsideration of hydrologic boundaries by forcing hydrologists and environmental historians to account for fisheries and harbor engineering alongside population and industry as factors in changes to water quality and quantity in and human response to urban nineteenth-century hydrologic change.

Dissonance-Based Interventions for Substance Using Alternative High-School Youth

Steiker, Lori Holleran; Powell, Tara

2011-01-01

This article describes an innovative new intervention tailored to older youth who are already abusing drugs, but who are not diagnostically ready for treatment. The basic tenet of this intervention is to utilize adolescents engaged in drug use as “experts” in the prevention curriculum adaptation activity. This activity then serves as a mechanism for their dissonance-based change. This process is designed to intervene with drug abusing youth prior to their development of substance dependence. The community-based design grew from a United States federally funded NIDA project (National Institute of Drug Abuse Mentored Research Scientist Award) which found that the youth who conduct program adaptations were effectively engaged, animatedly discussing the payoffs and downsides of drug and alcohol abuse. It is maintained through this research that dissonance between their role of “Preventionist” and their own substance abuse behaviors lead to shifts in attitudes and behaviors. Dissonance-based interventions (DBIs) have been successfully utilized for positive behavioral change with a variety of disorders, but have not yet been implemented with substance abusing youth. Findings of pilot research are shared along with implications for future research and interventions. PMID:22611306

Statistics of Petroleum Exploration in the World Outside the United States and Canada Through 2001

Future oil and gas supplies depend, in part, on the reserves that are expected to be added through exploration and new discoveries. This Circular presents a summary of the statistics and an analysis of petroleum exploration in the world outside the United States and Canada (the study area) through 2001. It updates U.S. Geological Survey Circular 1096 (by E.D. Attanasi and D.H. Root, 1993) and expands coverage of the statistics to areas where drilling and discovery data have recently become available. These new areas include China, the formerly Communist countries of Eastern Europe, and the countries that once were part of the former Soviet Union in Europe and Asia. Data are presented by country but are organized by petroleum provinces delineated by the U.S. Geological Survey World Energy Assessment Team (USGS Digital Data Series DDS?60, published in 2000). The data and analysis are presented in maps and graphs, providing a visual summary of the exploration maturity of an area. The maps show the delineated prospective areas and explored areas through 2001; explored areas have a drilling density that would rule out the occurrence of undetected large petroleum accumulations. Graphs summarize the exploration yields in terms of cumulative recoverable discovered oil and gas by delineated prospective area. From 1992 through 2001 in areas outside the United States and Canada, the delineated prospective area expanded at a rate of about 50,000 square miles per year while the explored area grew at the rate of about 11,000 square miles per year. The delineated prospective area established by 1970 contains about 75 percent of the oil discovered to date in the study area. This area is slightly less than 40 percent of the delineated prospective area established through 2001. Maps and graphs show the extension of the delineated prospective area to deepwater areas offshore of Brazil and West Africa. From 1991 through 2000, offshore discoveries accounted for 59 percent of the oil and 77 percent of the gas discovered in the study area. The petroleum industry's decision to incur the greater costs of moving offshore and into deeper waters appears to be a response to the absence of onshore prospects of comparable quality. Where natural gas can be commercially developed and marketed, data show an expansion of exploration to target gas-prone areas.

Use of World Health Organization and CDC growth charts for children aged 0-59 months in the United States.

PubMed

Grummer-Strawn, Laurence M; Reinold, Chris; Krebs, Nancy F

2010-09-10

In April 2006, the World Health Organization (WHO) released new international growth charts for children aged 0-59 months. Similar to the 2000 CDC growth charts, these charts describe weight for age, length (or stature) for age, weight for length (or stature), and body mass index for age. Whereas the WHO charts are growth standards, describing the growth of healthy children in optimal conditions, the CDC charts are a growth reference, describing how certain children grew in a particular place and time. However, in practice, clinicians use growth charts as standards rather than references. In 2006, CDC, the National Institutes of Health, and the American Academy of Pediatrics convened an expert panel to review scientific evidence and discuss the potential use of the new WHO growth charts in clinical settings in the United States. On the basis of input from this expert panel, CDC recommends that clinicians in the United States use the 2006 WHO international growth charts, rather than the CDC growth charts, for children aged <24 months (available at https://www.cdc.gov/growthcharts). The CDC growth charts should continue to be used for the assessment of growth in persons aged 2--19 years. The recommendation to use the 2006 WHO international growth charts for children aged <24 months is based on several considerations, including the recognition that breastfeeding is the recommended standard for infant feeding. In the WHO charts, the healthy breastfed infant is intended to be the standard against which all other infants are compared; 100% of the reference population of infants were breastfed for 12 months and were predominantly breastfed for at least 4 months. When using the WHO growth charts to screen for possible abnormal or unhealthy growth, use of the 2.3rd and 97.7th percentiles (or ±2 standard deviations) are recommended, rather than the 5th and 95th percentiles. Clinicians should be aware that fewer U.S. children will be identified as underweight using the WHO charts, slower growth among breastfed infants during ages 3-18 months is normal, and gaining weight more rapidly than is indicated on the WHO charts might signal early signs of overweight.

Subduction / exhumation dynamics: Petrochronology in the Glacier-Rafray slice (Western Alps, Italy)

NASA Astrophysics Data System (ADS)

Burn, Marco; Lanari, Pierre; Engi, Martin

2014-05-01

Petrochronology is the combination of in situ age-dating, geothermobarometry and structural geology and aims to unravel Pressure-Temperature-deformation-time (P-T-ɛ-t) paths. To link P-T conditions to deformation stages is daily business for metamorphic petrologists, but recent micro-mapping techniques (XMapTools program) provide an additional tool to achieve this goal. Absolute age is often difficult to assess in metamorphic rocks, as it is challenging to link specific P-T conditions to most of the mineral chronometers. Allanite is a common accessory phase in high-P metamorphic rocks and is a potential target to determine Th(-U)/Pb ages. Allanite from a leucocratic gneiss of the Glacier-Rafray slice in the western Alps consists of several chemically different zones: one major zone can be linked to a first high-P phengite generation. To determine the age of this high-P growth zone we used La-ICP-MS in situ techniques, which allowed us to date an appropriate growth rim per grain. Even so particular care was required when evaluating the isotope signals laser ablation leads to the excavation of a volume, which potentially can be chemically and/or age-zoned. We have developed a new method to track changes in the plasma during the ablation. This method aims to identify discrete age zones. La-ICP-MS spectra have been modeled so as to reproduce the shape of the spectra measured. These results indicate that high-P allanite first grew in equilibrium with phengite at 84 ± 4 Ma, whereas a second growth event occurred at ~40 Ma. A final epidotic rim grew at greenschist facies conditions, but this stage could not be dated. These findings have implications for our interpretation of several units in the Western Alps: In the Sesia Zone (former Adriatic margin), the earliest high-P metamorphism occurred at 85 Ma (Regis et al., 2014), precisely as the first high-P peak we discovered in the Glacier-Rafray slice. Austroalpine klippen such as this are commonly seen as extensional allochthons; one would expect these to have entered the subduction zone together with the Piemonte oceanic units. Yet all high-P ages reported for the Piemonte oceanic units are around 40 Ma. We propose that the Glacier-Rafray slice experienced subduction together with Sesia units and may have been juxtaposed on the Piemont-Ligurian-Ocean units during Eocene exhumation. Strain associated with this juxtaposition may have triggered growth of the second allanite. Joint exhumation of the oceanic units and the Glacier-Rafray klippe followed at retrograde T.

State-Level Trends in the Prevalence of Autism Spectrum Disorder (ASD) from 2000 to 2012: A Reanalysis of Findings from the Autism and Developmental Disabilities Network.

Since 2000, the Autism and Developmental Disabilities Network (ADDM) has published detailed prevalence estimates for autism spectrum disorder (ASD) among 8 year-olds, which are widely interpreted as the U.S. national prevalence of ASD. Although differences in state-level ASD prevalence has been reported, state-level heterogeneity has not been explored systematically. We analyzed state-level estimates and trends in ASD prevalence from 2000 to 2012 using secondary data from bi-annual ADDM reports. Heterogeneity among state-level ASD prevalence estimates were apparent in 2000 and grew between 2000 and 2012. Findings highlight the need for greater understanding of how children with ASD are identified by the medical and educational systems, which has significant implications for the state-level resources required to effectively manage ASD.

Growth of Ca{sub 2}MnO{sub 4} Ruddlesden-Popper structured thin films using combinatorial substrate epitaxy

2014-12-28

The local epitaxial growth of pulsed laser deposited Ca{sub 2}MnO{sub 4} films on polycrystalline spark plasma sintered Sr{sub 2}TiO{sub 4} substrates was investigated to determine phase formation and preferred epitaxial orientation relationships (ORs) for isostructural Ruddlesden-Popper (RP) heteroepitaxy, further developing the high-throughput synthetic approach called Combinatorial Substrate Epitaxy (CSE). Both grazing incidence X-ray diffraction and electron backscatter diffraction patterns of the film and substrate were indexable as single-phase RP-structured compounds. The optimal growth temperature (between 650 °C and 800 °C) was found to be 750 °C using the maximum value of the average image quality of the backscattered diffraction patterns. Films grew inmore » a grain-over-grain pattern such that each Ca{sub 2}MnO{sub 4} grain had a single OR with the Sr{sub 2}TiO{sub 4} grain on which it grew. Three primary ORs described 47 out of 49 grain pairs that covered nearly all of RP orientation space. The first OR, found for 20 of the 49, was the expected RP unit-cell over RP unit-cell OR, expressed as [100][001]{sub film}||[100][001]{sub sub}. The other two ORs were essentially rotated from the first by 90°, with one (observed for 17 of 49 pairs) being rotated about the [100] and the other (observed for 10 of 49 pairs) being rotated about the [110] (and not exactly by 90°). These results indicate that only a small number of ORs are needed to describe isostructural RP heteroepitaxy and further demonstrate the potential of CSE in the design and growth of a wide range of complex functional oxides.« less

Creating new growth platforms.

Sooner or later, most companies can't attain the growth rates expected by their boards and CEOs and demanded by investors. To some extent, such businesses are victims of their own successes. Many were able to sustain high growth rates for a long time because they were in high-growth industries. But once those industries slowed down, the businesses could no longer deliver the performance that investors had come to take for granted. Often, companies have resorted to acquisition, though this strategy has a discouraging track record. Over time, 65% of acquisitions destroy more value than they create. So where does real growth come from? For the past 12 years, the authors have been researching and advising companies on this issue. With the support of researchers at Harvard Business School and Insead, they instituted a project titled "The CEO Agenda and Growth". They identified and approached 24 companies that had achieved significant organic growth and interviewed their CEOs, chief strategists, heads of R&D, CFOs, and top-line managers. They asked, "Where does your growth come from?" and found a consistent pattern in the answers. All the businesses grew by creating new growth platforms (NGPs) on which they could build families of products and services and extend their capabilities into multiple new domains. Identifying NGP opportunities calls for executives to challenge conventional wisdom. In all the companies studied, top management believed that NGP innovation differed significantly from traditional product or service innovation. They had independent, senior-level units with a standing responsibility to create NGPs, and their CEOs spent as much as 50% of their time working with these units. The payoff has been spectacular and lasting. For example, from 1985 to 2004, the medical devices company Medtronic grew revenues at 18% per year, earnings at 20%, and market capitalization at 30%.

Staphylococcus aureus is a common cause of healthcare-associated infections in neonates. To examine the impact of methicillin-susceptible S. aureus (MSSA) decolonization on the incidence of MSSA infection and to measure the prevalence of mupirocin resistance. We retrospectively identified neonates admitted to a tertiary care neonatal intensive care unit (NICU) from April 1, 2011, through September 30, 2014. We compared rates of MSSA-positive cultures and infections before and after implementation of an active surveillance culture and decolonization intervention for MSSA-colonized neonates. We used 2 measurements to identify the primary outcome, NICU-attributable MSSA: (1) any culture sent during routine clinical care that grew MSSA and (2) any culture that grew MSSA and met criteria of the National Healthcare Safety Network's healthcare-associated infection surveillance definitions. S. aureus isolates were tested for mupirocin susceptibility. We estimated incidence rate ratios using interrupted time-series models. Before and after the intervention, 1,523 neonates (29,220 patient-days) and 1,195 neonates (22,045 patient-days) were admitted to the NICU, respectively. There was an immediate reduction in the mean quarterly incidence rate of NICU-attributable MSSA-positive clinical cultures of 64% (incidence rate ratio, 0.36 [95% CI, 0.19-0.70]) after implementation of the intervention, and MSSA-positive culture rates continued to decrease by 21% per quarter (incidence rate ratio, 0.79 [95% CI, 0.74-0.84]). MSSA infections also decreased by 73% immediately following the intervention implementation (incidence rate ratio, 0.27 [95% CI, 0.10-0.79]). No mupirocin resistance was detected. Active surveillance cultures and decolonization may be effective in decreasing S. aureus infections in NICUs.

For the past six years, the Chicago-area faith-based Reach Out Consortium has mobilized low-income uninsured and underinsured African American women and Latinas to seek screening for breast and cervical cancer. The funding history for this program illustrates how funds for a small community-based program were leveraged into a broader program, and that grew to serve low-income women across the state. Further, as the program reached more and more uninsured women, community activism led to a further state investment in services for the uninsured. Program sustainability and expansion depended on a combination of public and private competitive grants and grassroots advocacy.

Ecological relationships between xerophilic fungi and house-dust mites (Acarida: Pyroglyphidae).

At. 75 and 80% relative humidity (RH), on a wheat germ flake medium, Aspergillus penicilloides grew abundantly and suppressed the population growth of Dermatophagoides pteronyssiunus. At 71% RH, A. penicilloides grew moderately and was only antagonistic to D. pteronyssinus when the fungus was previously incubated on the medium.On a human dander medium and on mattress dust, A. penicilloides grew moderately at 71% and 75% RH and stimulated the development of D. pteronyssinus populations. Also a moderate growth of Eurotium repens on human dander positively influenced D. pteronyssinus. Wallemia sebi and Penicillium brevicompactum grew slightly or did not grow at all at 75% RH. No effect was observed on D. pteronyssinus.It appears that xerophilic fungi may stimulate, and occasionally may reduce, the growth of house-dust mite populations in the natural environment.

Ten strains of fungi were tested for tolerance to the fungicide benomyl. Verticillium chlamydosporium strain 2 did not grow in the presence of benomyl; Drechraeria coniospora strains 1 and 2 and Chaetomium sp. tolerated only 0.1 mug benomyl/ml medium; Acremonium bacillisporum, an unidentified fungus, and Phoma chrysanthemicola uniformly grew at 1 mug/ml, but some hyphae grew at higher benomyl concentrations; Fusarium sp. tolerated 475 mug/ml, but some hyphae grew on medium amended with 1,000 mug/ml; Verticillium lecanii and V. chlamydosporium strain 1 routinely tolerated 1,000 mug/ml. Fungi generally grew more slowly at higher than at lower benomyl concentrations. Strains with elevated tolerance to benomyl were selected from Acremonium bacillisporum, Drechmeria coniospora, Fusarium sp., and an unidentified fungus. These strains retained the increased tolerance after repeated transfers on unamended medium.

Plant cell wall is mainly composed by cellulose, hemicellulose and lignin. The heterogeneous structure and composition of the hemicellulose are key impediments to its depolymerization and subsequent use in fermentation processes. Thus, this study aimed to perform a screening of thermophilic and thermotolerant filamentous fungi collected from different regions of the São Paulo state, and analyze the production of β-xylosidase and arabinanase at different temperatures. These enzymes are important to cell wall degradation and synthesis of end products as xylose and arabinose, respectively, which are significant sugars to fermentation and ethanol production. A total of 12 fungal species were analyzed and 9 of them grew at 45 °C, suggesting a thermophilic or thermotolerant character. Additionally Aspergillus thermomutatus anamorph of Neosartorya and A. parasiticus grew at 50 °C. Aspergillus niger and Aspergillus thermomutatus were the filamentous fungi with the most expressive production of β-xylosidase and arabinanase, respectively. In general for most of the tested microorganisms, β-xylosidase and arabinanase activities from mycelial extract (intracellular form) were higher in cultures grown at high temperatures (35-40 °C), while the correspondent extracellular activities were favorably secreted from cultures at 30 °C. This study contributes to catalogue isolated fungi of the state of São Paulo, and these findings could be promising sources for thermophilic and thermotolerant microorganisms, which are industrially important due to their enzymes.

Coliform Bacteria for Bioremediation of Waste Hydrocarbons

Raw, domestic sewage of Kuwait City contained about 106 ml−1 colony forming units of Enterobacter hormaechei subsp. oharae (56.6%), Klebsiella spp. (36%), and Escherichia coli (7.4%), as characterized by their 16S rRNA-gene sequences. The isolated coliforms grew successfully on a mineral medium with crude oil vapor as a sole source of carbon and energy. Those strains also grew, albeit to different degrees, on individual n-alkanes with carbon chains between C9 and C36 and on the individual aromatic hydrocarbons, toluene, naphthalene, phenanthrene, and biphenyl as sole sources of carbon and energy. These results imply that coliforms, like other hydrocarbonoclastic microorganisms, oxidize hydrocarbons to the corresponding alcohols and then to aldehydes and fatty acids which are biodegraded by β-oxidation to acetyl CoA. The latter is a well-known key intermediate in cell material and energy production. E. coli cells grown in the presence of n-hexadecane (but not in its absence) exhibited typical intracellular hydrocarbon inclusions, as revealed by transmission electron microscopy. Raw sewage samples amended with crude oil, n-hexadecane, or phenanthrene lost these hydrocarbons gradually with time. Meanwhile, the numbers of total and individual coliforms, particularly Enterobacter, increased. It was concluded that coliform bacteria in domestic sewage, probably in other environmental materials too, are effective hydrocarbon-biodegrading microorganisms. PMID:29082238

Dopamine is critical in pathophysiology and therapy of schizophrenia. Many studies have reported altered dopaminergic activity in the dorsal but not ventral striatum in schizophrenia. Based on the largest genome-wide association study of schizophrenia to date, we calculated the polygenic risk score (PGRS) of each subject in a healthy general group, including all variations in the set of functionally related genes involved in dopamine neurotransmitter system. We aimed to test whether the genetic variations in the dopaminergic pathway that have been identified as associated with schizophrenia are related to the function of the striatum and to working memory. We found that a higher PGRS was significantly associated with impairment in working memory. Moreover, resting-state functional connectivity analysis revealed that as the polygenic risk score increased, the connections between left putamen and caudate and the default mode network grew stronger, while the connections with the fronto-parietal network grew weaker. Our findings may shed light on the biological mechanism underlying the "dopamine hypothesis" of schizophrenia and provide some implications regarding the polygenic effects on the dopaminergic activity in the risk for schizophrenia.

The second U.S. Microgravity Payload (USMP-2) was flown on the Space Shuttle in March 1994. It carried four major microgravity experiments plus a sophisticated accelerometer system to record the microgravity environment during USMP-2 operations. The USMP program is designed to accommodate experiments requiring extensive resources short of a full Spacelab mission, and the experiments are remotely operated and monitored. Results are reviewed from the four experiments: the Advanced Automated Directional Solidification Facility (AADSF), the Isothermal Dendrite Growth Experiment (IDGE), the Materiel por Etude des Phenomenes Interessant la Soldification sur Terre et en Orbite (MEPHISTO), and the Critical Fluid Light Scattering Experiment (Zeno). AASDF grew what is expected to be the largest steady-state sample ever of HgCdTe during 240 hours of operation. IDGE provided 60 growth cycles over a wide range of supercooling conditions studying the dendritic solidification of succinonitrile. MEPHISTO achieved 55 melt-solidify cycles and grew over 1 m of Bi/Sn alloy. Zeno located the critical point temperature for liquid Xe to 0.00001 K. IDGE and Zeno also provided the most extensive demonstrations to date of telescience.

Caring for the new uninsured: Hospital charity care for older people without coverage.

Despite near-universal coverage through Medicare, a number of elderly residents in the United States do not have health insurance coverage. To the author's knowledge, this study is the first to document trends in the use of hospital charity care by uninsured older people. Data from the New Jersey Charity Care Program, which subsidizes hospitals for services provided to low-income uninsured people, were used to analyze trends in charity care utilization by older people from 1999 to 2004. Charity care charges are standardized to uniform Medicaid reimbursement rates and inflation adjusted using the Medical Care Consumer Price Index. From 1999 to 2004, use of charity care by older people grew much faster than it did for younger patients. As a result, older people now account for a greater share of hospital charity care in New Jersey than children. Elderly users of charity care generated higher costs per patient than their younger counterparts. Cost differences were especially salient at the upper end of the distribution, where high-cost elderly patients used significantly more resources than high-cost patients in other age groups. These results highlight an emerging source of strain on the healthcare safety net and point to a growing population of uninsured residents who have costly and complex medical needs. Similar experiences are likely to be found in other states, especially those that have growing populations of elderly immigrants who are likely to lack health insurance.

Dental Therapists as New Oral Health Practitioners: Increasing Access for Underserved Populations.

The development of dental therapy in the U.S. grew from a desire to find a workforce solution for increasing access to oral health care. Worldwide, the research that supports the value of dental therapy is considerable. Introduction of educational programs in the U.S. drew on the experiences of programs in New Zealand, Australia, Canada, and the United Kingdom, with Alaska tribal communities introducing dental health aide therapists in 2003 and Minnesota authorizing dental therapy in 2009. Currently, two additional states have authorized dental therapy, and two additional tribal communities are pursuing the use of dental therapists. In all cases, the care provided by dental therapists is focused on communities and populations who experience oral health care disparities and have historically had difficulties in accessing care. This article examines the development and implementation of the dental therapy profession in the U.S. An in-depth look at dental therapy programs in Minnesota and the practice of dental therapy in Minnesota provides insight into the early implementation of this emerging profession. Initial results indicate that the addition of dental therapists to the oral health care team is increasing access to quality oral health care for underserved populations. As evidence of dental therapy's success continues to grow, mid-level dental workforce legislation is likely to be introduced by oral health advocates in other states. This article was written as part of the project "Advancing Dental Education in the 21 st Century."

Salt-mediated multicell formation in Deinococcus radiodurans.

PubMed Central

Chou, F I; Tan, S T

1991-01-01

The highly radiation-resistant tetracoccal bacterium Deinococcus radiodurans exhibited a reversible multi-cell-form transition which depended on the NaCl concentration in the medium. In response to 0.8% NaCl addition into the medium, the pair/tetrad (designated 2/4) cells in a young culture grew and divided but did not separate and became 8-, 16-, and 32-cell units successively. In exponential growth phase, the cells divided in a 16/32 pattern. Potassium ions were equally effective as Na+ in mediating this multicell-formation effect; Mg2+, Li+, and Ca2+ also worked but produced less multiplicity. This effect appears to be species specific. This-section micrographs revealed that in a 16/32-cell unit, eight 2/4 cells were encased in an orderly manner within a large peripheral wall, showing five cycles of septation. Our results suggest the presence of a salt-sensitive mechanism for controlling cell separation in D. radiodurans. Images PMID:2022617

A history of US Army PAs.

The US military has a long tradition of using physician assistants (PAs). The Army began using PAs in 1971 in an effort to supplement the physicians and surgeons in the medical corps. As their numbers grew, PAs gradually replaced general medical officers assigned to battalions. Later, specialty positions developed in aviation medicine, orthopedics, and emergency medicine. The need for a PA serving as an adviser in the major commands slowly developed at all levels of leadership. In 2015, the Army removed limitations on female PAs assigned to combat units. PAs lead in tactical and clinical settings, filling command roles, senior clinical positions, and administrative leadership roles.

A spacecraft hydroponic plant growth unit of tubular configuration, employing a microporous membrane as a capilary interface between plant roots and a nutrient solution, is presented. All three of the experimental trials undertaken successfully grew wheat from seed to harvest. Attention is given to the mass/seed, number of seeds/head, ratio of seed dry mass to total plant dry mass, production of tillers, and mass of seed/plant. Dry matter production is found to be reduced with increasing suction pressure; this is true for both average seed and average total dry matter/plant. This may be due to a reduction in water and nutrient availability through the microporous membrane.

Abnormal lignin in a loblolly pine mutant.

Novel lignin is formed in a mutant loblolly pine (Pinus taeda L.) severely depleted in cinnamyl alcohol dehydrogenase (E.C. 1.1.1.195), which converts coniferaldehyde to coniferyl alcohol, the primary lignin precursor in pines. Dihydroconiferyl alcohol, a monomer not normally associated with the lignin biosynthetic pathway, is the major component of the mutant's lignin, accounting for approximately 30 percent (versus approximately 3 percent in normal pine) of the units. The level of aldehydes, including new 2-methoxybenzaldehydes, is also increased. The mutant pines grew normally indicating that, even within a species, extensive variations in lignin composition need not disrupt the essential functions of lignin.

Governing new technology: A comparative analysis of government support for nanotechnology in the Netherlands and the United States

NASA Astrophysics Data System (ADS)

Eijmberts, Johannes

This study examines this variance in national government support for nanotechnology---its shape, size, and policy priorities---by comparing the United States and the Netherlands. Our operating hypothesis is that national government support for nanotechnology development is driven not by the intrinsic nature of the technology but by longstanding structural and institutional arrangements. That is, in the U.S., pluralist political traditions and reliance on classical liberal market economics would suggest a detached national government approach, leaving any initiative to market actors. At the same time, legacies of corporatism in the Dutch political system and a tradition of greater direct government involvement in the national economy would suggest a government-led policy on nanotechnology development. The findings show otherwise. Early on, the U.S. government established the National Nanotechnology Initiative, an overarching federal mechanism to promote and coordinate nanotechnology development. Yet, despite its appearance of central direction and coordination, the NNI reflected pluralist arrangements by leaving ample autonomy for participating federal departments and agencies. The creation of the NNI was driven particularly by concerns of about foreign challenges to American global leadership in science and technology. In the Netherlands, by contrast, the path taken shows the legacy of Dutch corporatist practice---slow, incremental, and embedded in pre-existing institutional arrangements. The Dutch government initially took no directive role, relying instead on established links among universities, public research funding organizations, and industries to advance nanotechnology development in the Netherlands. However, over time, Dutch government involvement in nanotechnology grew to be more supportive, sizeable, comprehensive, and directive---particulary by requiring substantial investments in risk-related research as a condition for public funding and, notably, by stated preference to embed Dutch efforts within in broader European policy frameworks. The findings broaden our insights into factors shaping government support for promising fields of science and technology, opportunities for multi-level governance of their effects, and the extent to which convergence in national approaches is a realistic possibility. Given the greater complexity of emerging fields of science and technology, how governments organize themselves to promote research and development---while also protecting public health and the environment---is an increasingly important question.

Economic and market issues on the sustainability of egg production in the United States: analysis of alternative production systems.

Conventional cage housing for laying hens evolved as a cost-effective egg production system. Complying with mandated hen housing alternatives would raise marginal production costs and require sizable capital investment. California data indicate that shifts from conventional cages to barn housing would likely cause farm-level cost increases of about 40% per dozen. The US data on production costs of such alternatives as furnished cages are not readily available and European data are not applicable to the US industry structure. Economic analysis relies on key facts about production and marketing of conventional and noncage eggs. Even if mandated by government or buyers, shifts to alternative housing would likely occur with lead times of at least 5 yr. Therefore, egg producers and input suppliers would have considerable time to plan new systems and build new facilities. Relatively few US consumers now pay the high retail premiums required for nonconventional eggs from hens housed in alternative systems. However, data from consumer experiments indicate that additional consumers would also be willing to pay some premium. Nonetheless, current data do not allow easy extrapolation to understand the willingness to pay for such eggs by the vast majority of conventional egg consumers. Egg consumption in the United States tends to be relatively unresponsive to price changes, such that sustained farm price increases of 40% would likely reduce consumption by less than 10%. This combination of facts and relationships suggests that, unless low-cost imports grew rapidly, requirements for higher cost hen housing systems would raise US egg prices considerably while reducing egg consumption marginally. Eggs are a low-cost source of animal protein and low-income consumers would be hardest hit. However, because egg expenditures are a very small share of the consumer budget, real income loss for consumers would be small in percentage terms. Finally, the high egg prices imposed by alternative hen housing systems raise complex issues about linking public policy costs to policy beneficiaries.

Effects of salinity on establishment of Populus fremontii (cottonwood) and Tamarix ramosissima (saltcedar) in southwestern United States

The exotic shrub Tamarix ramosissima (saltcedar) has replaced the native Populus fremontii(cottonwood) along many streams in southwestern United States. We used a controlled outdoor experiment to examine the influence of river salinity on germination and first year survival of P. fremontii var. wislizenii (Rio Grande cottonwood) and T. ramosissima on freshly deposited alluvial bars. We grew both species from seed in planters of sand subjected to a declining water table and solutions containing 0, 1, 3, and 5 times the concentrations of major ions in the Rio Grande at San Marcia, NM (1.2, 10.0, 25.7 and 37.4 meq 1-1; 0.11, 0.97, 2.37, and 3.45 dS m-1). Germination of P. fremontii declined by 35% with increasing salinity (P = .008). Germination of T. ramosissima was not affected. There were no significant effects of salinity on morality or above- and belowground growth of either species. In laboratory tests the same salinities had no effect onP. fremontii germination. P. fremontii germination is more sensitive to salinity outdoors than in covered petri dishes, probably because water scarcity resulting from eavaportion intensifies the low soil water potential associated with high salinity. River salinity appears to play only a minor role in determining relative numbers of P. fremontii and T. ramosissima seedlings on freshly deposited sandbars. However, over many years salt becomes concentrated on floodplains as a result of evaporation and salt extrusion from saltcedar leaves. T. ramosissima is known to be more tolerant of the resulting extreme salinities than P. fremontii. Therefore, increases in river salinities could indirectly contribute to decline of P. fremontii forests by exacerbating salt accumulation on floodplains.

Introduction Diabetes Mellitus (DM) is a huge burden for human health. Recent studies show the close relationship between DM and T cells. We investigated the trend in DM and T cells research. Methods Using the Web of Science database, we searched the publications on DM and T cells in 1997–2016, and studied the source data using bibliometric methodology. Excel 2016, GraphPad Prism 5, and VOSviewer software were used to analyze the publication trend in DM and T cells research. Results We found a total of 1077 publications with 38109 citations up to January 23, 2017. The highest contribution came from the United States, with 48.38% of the publications, 61.44% of the citations and the highest H-index (74). China had the 5th place for total publications, but ranked 11th both for citation frequency (604) and H-index (13). The inflection point of the global DM and T cells publications was in 2000. Journal of Immunology published the most related articles (164). Santamaria P. was the leading scholar in this field with the most publications (35). The keywords “regulatory T cell” and “autoimmune diabetes” were mentioned more than 300 times. Furthermore, type 2 (T2)DM, T cell immunoglobulin and mucin domain (TIM) and obesity are becoming popular research topics in this field. Conclusion The quantity of publications on DM and T cells grew rapidly around year 2000, but has relatively decreased recently. The United States had the leading position in global research. There was a discrepancy between productivity and quality of publications from China. Latest progress is most likely first published by the Journal of Immunology. Santamaria P., Roep B.O. and Peakman M. were the pioneer scholars in this field. Most researchers have focused on “regulatory T cell” and “autoimmune diabetes” research. In future, T2DM, TIM and obesity may be the popular areas. PMID:28926600

As people encroach increasingly on natural areas, one question is how this affects avian biodiversity. The answer to this is partly scale-dependent. At broad scales, human populations and biodiversity concentrate in the same areas and are positively associated, but at local scales people and biodiversity are negatively associated with biodiversity. We investigated whether there is also a systematic temporal trend in the relationship between bird biodiversity and housing development. We used linear regression to examine associations between forest bird species richness and housing growth in the conterminous United States over 30 years. Our data sources were the North American Breeding Bird Survey and the 2000 decennial U.S. Census. In the 9 largest forested ecoregions, housing density increased continually over time. Across the conterminous United States, the association between bird species richness and housing density was positive for virtually all guilds except ground nesting birds. We found a systematic trajectory of declining bird species richness as housing increased through time. In more recently developed ecoregions, where housing density was still low, the association with bird species richness was neutral or positive. In ecoregions that were developed earlier and where housing density was highest, the association of housing density with bird species richness for most guilds was negative and grew stronger with advancing decades. We propose that in general the relationship between human settlement and biodiversity over time unfolds as a 2-phase process. The first phase is apparently innocuous; associations are positive due to coincidence of low-density housing with high biodiversity. The second phase is highly detrimental to biodiversity, and increases in housing density are associated with biodiversity losses. The long-term effect on biodiversity depends on the final housing density. This general pattern can help unify our understanding of the relationship of human encroachment and biodiversity response. © 2014 Society for Conservation Biology.

On a new schedule: transitions to adulthood and family change.

Frank Furstenberg examines how the newly extended timetable for entering adulthood is affecting, and being affected by, the institution of the Western, particularly the American, family. He reviews a growing body of research on the family life of young adults and their parents and draws out important policy implications of the new schedule for the passage to adulthood. Today, says Furstenberg, home-leaving, marriage, and the onset of childbearing take place much later in the life span than they did during the period after World War II. After the disappearance of America's well-paying unskilled and semi-skilled manufacturing jobs during the 1960s, youth from all economic strata began remaining in school longer and marrying and starting their own families later. Increasing numbers of lower-income women did not marry at all but chose, instead, non-marital parenthood-often turning to their natal families for economic and social support, rather than to their partners. As the period of young adults' dependence on their families grew longer, the financial and emotional burden of parenthood grew heavier. Today, regardless of their income level, U.S. parents provide roughly the same proportion of their earnings to support their young adult children. Unlike many nations in Europe, the United States, with its relatively underdeveloped welfare system, does not invest heavily in education, health care, and job benefits for young adults. It relies, instead, on families' investments in their own adult children. But as the transition to adulthood becomes more protracted, the increasing family burden may prove costly to society as a whole. Young adults themselves may begin to regard childbearing as more onerous and less rewarding. The need to provide greater support for children for longer periods may discourage couples from having additional children or having children at all. Such decisions could lead to lower total fertility, ultimately reduce the workforce, and furthdr aggravate the problem of providing both for increasing numbers of the elderly and for the young. U.S. policy makers must realize the importance of reinforcing the family nest and helping reduce the large and competing demands that are being placed on today's parents.

Chronic hepatitis C virus (HCV) infection can lead to advanced liver disease (AdvLD), including cirrhosis, decompensated cirrhosis, and liver cancer. The aim of this study was to determine recent historical rates of HCV patient progression to AdvLD and to project AdvLD prevalence through 2015. We first determined total 2008 US chronic HCV prevalence from the National Health and Nutrition Evaluation Surveys. Next, we examined disease progression and associated non-pharmacological costs of diagnosed chronic HCV-infected patients between 2007-2009 in the IMS LifeLink and CMS Medicare claims databases. A projection model was developed to estimate AdvLD population growth through 2015 in patients diagnosed and undiagnosed as of 2008, using the 2007-2009 progression rates to generate a "worst case" projection of the HCV-related AdvLD population (i.e., scenario where HCV treatment is the same in the forecasted period as it was before 2009). We found that the total diagnosed chronic HCV population grew from 983,000 to 1.19 million in 2007-2009, with patients born from 1945-1964 accounting for 75.0% of all patients, 83.7% of AdvLD patients, and 79.2% of costs in 2009, indicating that HCV is primarily a disease of the "baby boomer" population. Non-pharmacological costs grew from $7.22 billion to $8.63 billion, with the majority of growth derived from the 60,000 new patients that developed AdvLD in 2007-2009, 91.5% of whom were born between 1945 and 1964. The projection model estimated the total AdvLD population would grow from 195,000 in 2008 to 601,000 in 2015, with 73.5% of new AdvLD cases from patients undiagnosed as of 2008. AdvLD prevalence in patients diagnosed as of 2008 was projected to grow 6.5% annually to 303,000 patients in 2015. These findings suggest that strategies to diagnose and treat HCV-infected patients are urgently needed to increase the likelihood that progression is interrupted, particularly for patients born from 1945-1964.

Science, state, and spirituality: Stories of four creationists in South Korea.

PubMed

Park, Hyung Wook; Cho, Kyuhoon

This paper presents an analysis of the birth and growth of scientific creationism in South Korea by focusing on the lives of four major contributors. After creationism arrived in Korea in 1980 through the global campaign of leading American creationists, including Henry Morris and Duane Gish, it steadily grew in the country, reflecting its historical and social conditions, and especially its developmental state with its structured mode of managing science and appropriating religion. We argue that while South Korea's creationism started with the state-centered conservative Christianity under the government that also vigilantly managed scientists, it subsequently constituted some technical experts' efforts to move away from the state and its religion and science through their negotiation of a new identity as Christian intellectuals ( chisigin). Our historical study will thus explain why South Korea became what Ronald Numbers has called "the creationist capital of the world."

Growth and variability in health plan premiums in the individual insurance market before the Affordable Care Act.

Gruber, Jonathan

2014-06-01

Before we can evaluate the impact of the Affordable Care Act on health insurance premiums in the individual market, it is critical to understand the pricing trends of these premiums before the implementation of the law. Using rates of increase in the individual insurance market collected from state regulators, this issue brief documents trends in premium growth in the pre-ACA period. From 2008 to 2010, premiums grew by 10 percent or more per year. This growth was also highly variable across states, and even more variable across insurance plans within states. The study suggests that evaluating trends in premiums requires looking across a broad array of states and plans, and that policymakers must examine how present and future changes in premium rates compare with the more than 10 percent per year premium increases in the years preceding health reform.

To analyze the trends and developments among journals in the specialty of obstetrics and gynecology. Using the Journal Citation Reports from 2007 to 2013, we analyzed the impact factor (IF), Eigenfactor® Score (ES), and Article Influence® Score (AIS) of 43 journals in the field of obstetrics and gynecology published in this time period. From 78 journals of the Journal Citation Report 2013, 43 were selected for this study. The mean IF grew from 1.68 ± 0.97 in 2007 to 2.12 ± 1.05 in 2013, the ES from 0.0113 ± 0.0169 to 0.0114 ± 0.0140, and the AIS from 0.513 ± 0.302 to 0.663 ± 0.359. Differences in the IF, ES, and AIS between journals from the United States versus Europe could be observed. In most cases, the IF, ES, and AIS increased between 2007 and 2013. Strong correlations could be found between IF, AIS, and ES. The overall mean IF for obstetrical and gynecological journals increased over the analyzed time period. The IF remains the standard measure to compare scientific journals. It correlates well with two major alternative measures of scientific impact, the ES and especially the AIS. Other measures are evolving and might show superior usage in the future.

Reversing urban decay: brownfield redevelopment and environmental health.

While the United States government concentrates more of its political and financial resources on fighting terrorism, the continuing decay of older cities and industrial suburbs has fallen far down on the national political priority agenda. An exception is the redevelopment of so-called brownfields, which are abandoned, idled, or underutilized factories, railroad yards, bus stations, garages, electricity-generating stations, and other commercial facilities. A modest national government program to identify, clean up, and redevelop brownfields into job fields began during the administration of Bill Clinton and has continued into the George W. Bush administration (Powers et al. 2000; Simons 1998; Van Horn et al. 1999). The political reasons are apparent: Developing brownfields is a politically acceptable method of stimulating private enterprise, local government, and community groups into building new businesses, housing, and community facilities. Also, brownfields projects have a beginning and an end; the national government does not have an indefinite responsibility. In contrast, social assistance programs that grew during the 1960s and proliferated for more than three decades have been politically portrayed by some as give-away programs that build dependency with no ending. Whether this characterization of social programs is morally or empirically justified, the reality is that in today's political environment brownfields redevelopment is a politically acceptable way of helping distressed urban areas.

I assessed recent trends in prevalence of any contact with mental health professionals and nonuse of mental health care or prescription medications owing to cost among adults with significant psychological distress. In samples drawn from the National Health Interview Survey of 1997-2002, multiple logistic regression analysis was used to examine the association of survey year with mental health professional contacts and nonuse of mental health care or prescription medications owing to cost. The prevalence of any contact with mental health professionals increased from 29.1% in 1997 to 35.5% in 2002 (P<.05). The prevalence of nonuse of services because of cost also increased-from 15.6% to 20.0% for mental health care (P<.05) and from 27.7% to 34.1% for medication use (P<.001). Age, racial/ethnic, income, and insurance status disparities in receiving care persisted over the study period. The number of individuals in need of mental health care who contacted mental health professionals grew in recent years, as did the number of individuals who encountered cost barriers to such care. Barring dramatic improvements in health insurance coverage, more individuals will likely face such barriers in coming years.

Examining the communication skills of a young cochlear implant pioneer.

The purpose of this longitudinal case study was to closely examine one deaf child's experience with a cochlear implant and his speech, language, and communication skills from kindergarten through middle and high school using both developmental and sociocultural frameworks. The target child was one of the first children to receive a cochlear implant in the United States in 1988, when he was 5 years of age. The developmental analysis revealed that prior to receiving a cochlear implant the child demonstrated profound delays in speech and language skill development. His speech and language skills grew slowly during the first 3-4 years following implantation, very rapidly from about 5 through 7 years postimplantation, then slowed to rates that were highly similar to same-age peers with normal hearing. The sociocultural analysis revealed that the child's communicative competence improved; that he used sign language but use of sign language decreased as his oral communication skills improved; that as his oral communication skills improved, the adults talked and directed the topic of conversation less frequently; and that topics became less concrete and more personal over time. The results of this study indicate that we may learn more about how to support children who use cochlear implants by examining what they are saying as well as how they are saying it.

Rainfall-runoff in the Albuquerque, New Mexico, area: Measurements, analyses and comparisons

Albuquerque, New Mexico, has experienced significant growth over the last 20 years like many other cities in the Southwestern United States. While the US population grew by 37% between the 1970 and 2000 censuses, the growth for Albuquerque was 83%. More people mean more development and increased problems of managing runoff from urbanizing watersheds. The U.S. Geological Survey (USGS) in cooperation with the Albuquerque Arroyo Metropolitan Flood Control Authority (AMAFCA) and the City of Albuquerque has maintained a rainfall-runoff data collection program since 1976. The data from measured precipitation events can be used to verify hydrologic modeling. In this presentation, data from a representative gaged watershed is analyzed and discussed to set the overall framework for the rainfall-runoff process in the Albuquerque area. Of particular interest are the basic relationships between rainfall and watershed runoff response and an analysis of curve numbers as an indicator of runoff function. In urbanized areas, four land treatment types (natural, irrigated lawns, compacted soil, and impervious) are used to define surface infiltration conditions. Rainfall and runoff gage data are used to compare curve number (CN) and initial abstraction/uniform infiltration (IA/INF) techniques in an Albuquerque watershed. The IA/INF method appears to produce superior results over the CN method for the measured rainfall events.

The effects of gap size and disturbance type on invasion of wet pine savanna by cogongrass, Imperata cylindrica (Poaceae)

Cogongrass is a nonindigenous species perceived to threaten native communities of the southeastern United States through modification of species composition and alteration of community processes. To examine how gap size and disturbance type influence the invasion of wet pine savannas by cogongrass, we performed three field experiments to evaluate the response of cogongrass seeds and transplanted seedlings to four different gap sizes, four types of site disturbance, and recent burning of savanna vegetation. Cogongrass germinated, survived, and grew in all gap sizes, from 0 to 100 cm in diameter. Similarly, disturbance type had no effect on germination or seedling and transplant survival. Tilling, however, significantly enhanced transplanted seedling growth, resulting in a tenfold increase in biomass over the other disturbance types. Seedling survival to 1 and 2 mo was greater in burned savanna than unburned savanna, although transplant survival and growth were not affected by burning. Results of this study suggest that cogongrass can germinate, survive, and grow in wet pine savanna communities regardless of gap size or type of disturbance, including burning. Burning of savanna vegetation may enhance establishment by improving early seedling survival, and soil disturbance can facilitate invasion of cogongrass by enhancing plant growth.

Salinity tolerance and mycorrhizal responsiveness of native xeroriparian plants in semi-arid western USA

Beauchamp, Vanessa B.; Walz, C.; Shafroth, P.B.

2009-01-01

Restoration of salt-affected soils is a global concern. In the western United States, restoration of salinized land, particularly in river valleys, often involves control of Tamarix, an introduced species with high salinity tolerance. Revegetation of hydrologically disconnected floodplains and terraces after Tamarix removal is often difficult because of limited knowledge regarding the salinity tolerance of candidate native species for revegetation. Additionally, Tamarix appears to be non-mycorrhizal. Extended occupation of Tamarix may deplete arbuscular mycorrhizal fungi in the soil, further decreasing the success of revegetation efforts. To address these issues, we screened 42 species, races, or ecotypes native to southwestern U.S. for salinity tolerance and mycorrhizal responsiveness. As expected, the taxa tested showed a wide range of responses to salinity and mycorrhizal fungi. This variation also occurred between ecotypes or races of the same species, indicating that seed collected from high-salinity reference systems is likely better adapted to harsh conditions than seed originating from less saline environments. All species tested had a positive or neutral response to mycorrhizal inoculation. We found no clear evidence that mycorrhizae increased salinity tolerance, but some species were so dependent on mycorrhizal fungi that they grew poorly at all salinity levels in pasteurized soil. ?? 2009 Elsevier B.V.

Intense OI 630.0 nm emission depletions were detected over Mexico by an all-sky imager during the main phase of the geomagnetic storm on 1 June 2013 (minimum Dst index: -119 nT). Those emission depletions were interpreted to be associated with equatorial plasma bubbles. If bubbles were responsible for those middle-latitude emission depletions, they would have been extreme bubbles which extended over 40° magnetic latitudes and 7000 km in altitude at the magnetic equator. However, a few factors challenge this interpretation. First, the emission depletions detected over Mexico showed westward drift, whereas the equatorial ionosphere including bubbles drifted eastward on that night. Second, the middle-latitude emission depletions were tilted westward with respect to the geographic meridian, but the westward tilt of bubbles was not identified. Third, the growth of bubbles was not evident when the middle-latitude emission depletions grew. The westward tilt and westward propagation of the middle-latitude emission depletions are consistent with the characteristics of medium-scale traveling ionospheric disturbances (MSTIDs) observed over the United States on that night. Thus, the emission depletions over Mexico can be interpreted to be the signature of MSTIDs.

Snake fungal disease (SFD) is an emerging disease of conservation concern in eastern North America. Ophidiomyces ophiodiicola, the causative agent of SFD, has been isolated from over 30 species of wild snakes from six families in North America. Whilst O. ophiodiicola has been isolated from captive snakes outside North America, the pathogen has not been reported from wild snakes elsewhere. We screened 33 carcasses and 303 moulted skins from wild snakes collected from 2010-2016 in Great Britain and the Czech Republic for the presence of macroscopic skin lesions and O. ophiodiicola. The fungus was detected using real-time PCR in 26 (8.6%) specimens across the period of collection. Follow up culture and histopathologic analyses confirmed that both O. ophiodiicola and SFD occur in wild European snakes. Although skin lesions were mild in most cases, in some snakes they were severe and were considered likely to have contributed to mortality. Culture characterisations demonstrated that European isolates grew more slowly than those from the United States, and phylogenetic analyses indicated that isolates from European wild snakes reside in a clade distinct from the North American isolates examined. These genetic and phenotypic differences indicate that the European isolates represent novel strains of O. ophiodiicola. Further work is required to understand the individual and population level impact of this pathogen in Europe.

We evaluated state-level characteristics associated with cigarette excise taxes before and after the Master Settlement Agreement (MSA). We gathered annual cigarette excise tax rates for all US states and the District of Columbia, between 1981 and 2011, and matched each state-year tax rate with economic, political, attitudinal, and demographic characteristics, creating a data set of 1581 observations. We used panel data regression techniques to assess relationships between key characteristics and state cigarette excise tax levels. Cigarette excise tax rates grew at more than 6 times the rate of inflation between 1981 and 2011; growth varied by time period and region. We found strong negative associations between Republican Party control of state legislatures and governors' offices and state cigarette tax rates. Tobacco production, citizens' attitudes toward taxes and tobacco control, and cigarette tax rates in neighboring states were significantly associated with cigarette tax rates. We found no association between unemployment and tax rates. Future excise tax growth rate may depend more on the political leanings of state legislators, and the attitudes of the people they represent, than on economic circumstances.

Bacterial contamination of fabric and metal-bead identity card lanyards: a cross-sectional study.

In healthcare, fabric or metal-bead lanyards are universally used for carrying identity cards. However there is little information on microbial contamination with potential pathogens that may readily re-contaminate disinfected hands. We examined 108 lanyards from hospital staff. Most grew skin flora but 7/108 (6%) had potentially pathogenic bacteria: four grew methicillin-susceptible Staphylococcus aureus, and four grew probable fecal flora: 3 Clostridium perfringens and 1 Clostridium bifermentans (one lanyard grew both S. aureus and C. bifermentans). Unused (control) lanyards had little or no such contamination. The median duration of lanyard wear was 12 months (interquartile range 3-36 months). 17/108 (16%) of the lanyards had reportedly undergone decontamination including wiping with alcohol, chlorhexidine or chlorine dioxide; and washing with soap and water or by washing machine. Metal-bead lanyards had significantly lower median bacterial counts than those from fabric lanyards (1 vs. 4 CFU/cm(2); Mann-Whitney U=300.5; P<0.001). 12/32 (38%) of the metal-bead lanyards grew no bacteria, compared with 2/76 (3%) of fabric lanyards. We recommend that an effective decontamination regimen be instituted by those who use fabric lanyards, or that fabric lanyards be discarded altogether in preference for metal-bead lanyards or clip-on identity cards.

1995-10-01

The goal to develop and implement a new model of nursing care delivery grew out of administrative and shared governance initiatives to improve the quality of nursing care. This evaluative study used both quantitative and qualitative methods. Seven principles related to quality were identified and became the driving force behind the changes. Aspects of these changes in care delivery were piloted on a neurological unit and included implementation of collaborative rounds, a modular structure, role changes, and work redesign. Frequency distribution, questionnaire, focus group, and financial data indicated that there had been improvement in the delivery of care in addition to financial benefits. A considerable amount of the data provided evidence that supported continuing the changes.

Formation and Growth of New Organic Aerosol Particles over the Deepwater Horizon Oil Spill

2011-12-01

Aerosol size distributions were measured in June 2010 downwind of the surface oil slick produced by the Deepwater Horizon oil spill in the Gulf of Mexico. Rapid condensation of partially oxidized hydrocarbons was responsible for formation of a plume of secondary organic aerosol downwind of the spill region. New particles were nucleated upwind of the freshest surface oil but downwind of oil that surfaced less than 100 hours previously. These new particles grew by condensation at rates of ~20 nm hr-1; preexisting accumulation mode particles grew by ~10 nm hr-1. The gas-phase concentration of a condensing species necessary to support the observed growth rate assuming irreversible adsorption with unit accommodation coefficient is estimated to be ~0.04-0.09 μg m-3 (~3-8 pptv). The ratio of growth rates for newly formed particles to accumulation mode particles was consistent within error limits with irreversible condensation. Because new particle formation did not occur in areas away from the <100 hr-old oil slick, these results indicate that the oxidation products of VOC species, probably C14-C16 compounds, were directly involved in the growth of the new particles. While a unique and extreme environment, the oil spill plume provides insight into similar processes that may occur in urban and industrial areas where petrochemical products are produced and consumed.

In the last two centuries, age at menarche has decreased in several European populations, whereas adult height has increased. It is unclear whether these trends have ceased in recent years or how age at menarche and height are related in individuals. In this study, the authors first investigated trends in age at menarche and adult height among 286,205 women from nine European countries by computing the mean age at menarche and height in 5-year birth cohorts, adjusted for differences in socioeconomic status. Second, the relation between age at menarche and height was estimated by linear regression models, adjusted for age at enrollment between 1992 and 1998 and socioeconomic status. Mean age at menarche decreased by 44 days per 5-year birth cohort (beta = -0.12, standard error = 0.002), varying from 18 days in the United Kingdom to 58 days in Spain and Germany. Women grew 0.29 cm taller per 5-year birth cohort (standard error = 0.007), varying from 0.42 cm in Italy to 0.98 cm in Denmark. Furthermore, women grew approximately 0.31 cm taller when menarche occurred 1 year later (range by country: 0.13-0.50 cm). Based on time trends, more recent birth cohorts have their menarche earlier and grow taller. However, women with earlier menarche reach a shorter adult height compared with women who have menarche at a later age.

Holocene Migrations of Creosote Bush and Pinyon Pines in the Western United States: Implications for the Next Century.

The biogeographic histories of plant species of the arid western United States are becoming evident as more local paleoecological series are developed and compiled into regional databases. Plant macrofossils from packrat (Neotoma spp.) middens have been especially useful for reconstructing past distributions of arid and semi-arid species such as creosote bush (Larrea tridentata) and one and two-needle pinyon pines (Pinus monophylla, P. edulis). These records document the late Wisconsinan ranges of these species and their subsequent Holocene migrations into their current ranges. Creosote bush grew in the lower Colorado River Valley during the late Wisconsinan (Isotope Stage 2). Starting around 11,000 yr B.P., it migrated northward into its present range. By 6000 yr B.P. it grew at higher elevations than at present in the central Mojave Desert, but did not reach its extreme northern limits until around 4000 yr B.P. Other populations, such as near the shrubs upstream limit along the Colorado River, were not established until the last 2500 years. Its arrival at its most northerly sites lagged well behind other desert thermophiles. Single-needle pinyon (Pinus monophylla) migrated northward from the Mojave Desert into the Great Basin arriving near its current northeastern limit in the eastern Great Basin as early as 7000 yr B.P. It migrated more slowly in the western Great Basin possibly not reaching its northwestern limit until the last 2000 years. Colorado pinyon (Pinus edulis) migrated from near its current southern boundary northward reaching the eastern Grand Canyon as early as 10,600 yr B.P. It is not recorded from central Utah until after 7000 yr B.P. It evidently moved northward slowly, arriving at some northerly and easterly stands only within the last 1000 years. These migrational histories reflect a combination of dispersal limitations and gradual climatic changes. But the long migration times required, coupled with their expansion above their modern elevational limits during the middle Holocene, suggest that the primary factor slowing their response was migrational distance rather than a monotonic trend of warming climates through the Holocene. These results have implications for vegetational effects of the expected climate shifts of the next 100 years. Although this change may be as little as a third as the 6oC warming that occurred near the beginning of the Holocene, the past rates of migration suggest that little equilibration with the new climate can be expected in time spans under 1000 years. Also, mapping of 20 climate variables describing the modern climatic tolerances of these species suggests that they already have significant available potential range, mostly to the north of their current ranges, that should now be suitable for their expansion. These results suggest that either the late Holocene populations had not yet equilibrated with the Pleistocene to Holocene change in climate, or that climate has already warmed so much since the Little Ice Age that many species are no longer in equilibrium with late Twentieth Century climate.

Mycobacterium abscessus, an emerging pathogen in healthcare settings, has rarely been associated with community outbreaks. During February-May 2013, Idaho public health officials and pediatric infectious disease physicians investigated an outbreak of M abscessus skin infections in children whose only common exposure was an indoor wading pool. Healthcare providers and parents reported possible M abscessus cases. We used a standardized questionnaire to interview parents of affected children. Clinical specimens were submitted for mycobacterial examination. We conducted an environmental investigation of the pool. Microbial isolates from clinical and environmental samples were identified by sequencing polymerase chain reaction amplicons and underwent pulsed-field gel electrophoresis. Twelve cases were identified. Specimens from 4 of 7 children grew M abscessus or Mycobacterium abscessus/Mycobacterium chelonae . Ten (83%) of 12 children were female; median age was 3 years (range, 2 to 6 years); and all were immunocompetent. Pool maintenance did not fully comply with Idaho state rules governing pool operation. Mycobacterium abscessus/chelonae was isolated from pool equipment. Pulsed-field gel electrophoresis composite patterns were 87% similar between isolates from the pool ladder and 1 patient, and they were 90% similar between isolates from 2 patients. Environmental remediation included hyperchlorination, scrubbing and disinfection of pool surfaces, draining the pool, and replacement of worn pool materials. Immunocompetent children acquired M abscessus cutaneous infection involving hands and feet after exposure to a wading pool. Environmental remediation and proper pool maintenance likely halted transmission. Medical and public health professionals' collaboration effectively detected and controlled an outbreak caused by an emerging recreational waterborne pathogen.

The Federal Radiological Monitoring and Assessment Center (FRMAC) is a federal emergency response asset whose assistance may be requested by the Department of Homeland Security (DHS), the Department of Defense (DoD), the Environmental Protection Agency (EPA), the Nuclear Regulatory Commission (NRC), and state and local agencies to respond to a nuclear or radiological incident. It is an interagency organization with representation from the Department of Energy’s National Nuclear Security Administration (DOE/NNSA), the Department of Defense (DoD), the Environmental Protection Agency (EPA), the Department of Health and Human Services (HHS), the Federal Bureau of Investigation (FBI), and other federal agencies. FRMAC,more » in its present form, was created in 1987 when the radiological support mission was assigned to the DOE’s Nevada Operations Office by DOE Headquarters. The FRMAC asset, including its predecessor entities, was created, grew, and evolved to function as a response to radiological incidents. Radiological emergency response exercises showed the need for a coordinated approach to managing federal emergency monitoring and assessment activities. The mission of FRMAC is to coordinate and manage all federal radiological environmental monitoring and assessment activities during a nuclear or radiological incident within the United States in support of state,local, tribal governments, DHS, and the federal coordinating agency. Radiological emergency response professionals with the DOE’s national laboratories support the Radiological Assistance Program (RAP), National Atmospheric Release Advisory Center (NARAC), the Aerial MeasuringSystem (AMS), and the Radiation Emergency Assistance Center/Training Site (REAC/TS). These teams support the FRMAC to provide: Atmospheric transport modeling; Radiation monitoring; Radiological analysis and data assessments; and Medical advice for radiation injuries In support of field operations, the FRMAC provides geographic information systems, communications, mechanical, electrical, logistics, and administrative support. The size of the FRMAC is tailored to the incident and is comprised of emergency response professionals drawn from across the federal government. State and local emergency response teams may also integrate their operations with FRMAC, but are not required to.« less

Over the past two decades, nursing homes and home health care agencies have been influenced by several Medicare and Medicaid policy changes including the adoption of prospective payment for Medicare-paid postacute care and Medicaid-paid long-term home and community-based care reforms. This article examines how spending growth in these sectors was affected by state certificate-of-need (CON) laws, which were designed to limit the growth of providers and have remained unchanged for several decades. Compared with states without CON laws, Medicare and Medicaid spending in states with CON laws grew faster for nursing home care and more slowly for home health care. In particular, we observed the slowest growth in community-based care in states with CON for both the nursing home and home health industries. Thus, controlling for other factors, public postacute and long-term care expenditures in CON states have become dominated by nursing homes. © The Author(s) 2015.

It is shown that in darkness the spores of moss Funaria hygrometrica Hedw. germinated polarly under the influence of gravity. At the beginning the rhizoids appeared. They grew downwards. Then future chloronematical stolons started to form a germination spore. Usually, they grew upwards. Clinorotation or horizontal placing of Petry dishes could discoordinate such a gravisensitivity.

Invasion of an occupied niche by the crayfish Orconectes rusticus: potential importance of growth and mortality.

PubMed

Hill, Anna M; Sinars, Damon M; Lodge, David M

1993-06-01

We are exploring mechanisms of an invasion that contradicts the oft-cited generalization that species invade vacant niches. In northern Wisconsin lakes, the introduced crayfish Orconectes rusticus is replacing two ecologically similar resident congeners, O. virilis and O. propinquus. In laboratory experiments, we compared growth and mortality of individually maintained crayfish offered one of five ad libitum diets: invertebrates, macrophytes, dentritus, periphyton or all items combined. Mortality was highest for O. virilis and lowest for O. rusticus. Macrophyte diets yielded the highest mortality. All three species grew best on invertebrate and combination diets but grew little or not at all on diets of periphyton, detritus or macrophytes. O. rusticus and O. virilis grew more than O. propinquus. O. rusticus grew more quickly and/or was better able to survive overall than its congeners. Therefore, O. rusticus would probably have advantages over O. virilis and O. propinquus in competitive interactions, reproductive success and avoiding size-selective fish predation. Subtle interspecific differences may interact strongly with other ecological factors and contribute to the displacement of resident species from a well-occupied niche.

The environment is a well-known source of health care-acquired infection. Because of the known risk of contamination, patient privacy curtains require frequent changes to decrease the risk of spread from patients to curtain and visa versa. Fourteen disposable sporicidal privacy curtains were tested from December 2012 to June 2013 while hanging in a busy intensive care unit. Significant bacterial pathogens were identified and total bacteria enumerated as colony-forming units. Antimicrobial activity of curtain swatches was also tested against a range of bacteria in the laboratory. Measurements were recorded as zone of inhibition and contact inhibition. A cost analysis to replace standard curtains with disposable sporicidal curtains was also undertaken. Cultures grew low numbers of skin and environmental microorganisms with no methicillin-resistant Staphylococcus aureus, carbapenem-resistant Enterobacteriaceae, or Clostridium difficile detected. Vancomycin-resistant enterococci were recovered in very low numbers from 2 curtains where vancomycin-resistant enterococci-infected patients had been located. Privacy curtains demonstrated antimicrobial activity against C difficile and 13 additional bacterial pathogens. We conclude that disposable sporicidal privacy curtains are cost-effective and best replaced at 6 months in a high-risk area such as an intensive care unit.

This study compared the BD GeneOhm methicillin-resistant Staphylococcus aureus (MRSA) real-time PCR assay to culture by the use of BBL CHROMagar MRSA for the detection of MRSA in 627 nasal surveillance specimens collected from intensive care unit (ICU) patients. The PCR assay had a sensitivity, specificity, positive predictive value, and negative predictive value of 100%, 96.7%, 70.3%, and 100%, respectively. Nine of 19 false-positive PCR specimens grew methicillin-susceptible S. aureus (MSSA) from broth enrichment culture, of which two demonstrated evidence of mecA gene dropout. Compared to culture by the use of BBL CHROMagar MRSA, the BD GeneOhm MRSA PCR assay demonstrated sensitivity and specificity above 95% for the detection of MRSA nasal colonization and provided shorter turnaround time in generating positive and negative final results.

Arabidopsis plants were grown on the International Space Station within specialized hardware that combined a plant growth habitat with a camera system that can capture images at regular intervals of growth. The Imaging hardware delivers telemetric data from the ISS, specifically images received in real-time from experiments on orbit, providing science without sample return. Comparable Ground Controls were grown in a sister unit that is maintained in the Orbital Environment Simulator at Kennedy Space Center. One of many types of biological data that can be analyzed in this fashion is root morphology. Arabidopsis seeds were geminated on orbit on nutrient gel Petri plates in a configuration that encouraged growth along the surface of the gel. Photos were taken every six hours for the 15 days of the experiment. In the absence of gravity, but the presence of directional light, spaceflight roots remained strongly negatively phototropic and grew in the opposite direction of the shoot growth; however, cultivars WS and Col-0 displayed two distinct, marked differences in their growth patterns. First, cultivar WS skewed strongly to the right on orbit, while cultivar Col-0 grew with little deviation away from the light source. Second, the Spaceflight environment also impacted the rate of growth in Arabidopsis. The size of the Flight plants (as measured by primary root and hypocotyl length) was uniformly smaller than comparably aged Ground Control plants in both cultivars. Skewing and waving, thought to be gravity dependent phenomena, occur in spaceflight plants. In the presence of an orienting light source, phenotypic trends in skewing are gravity independent, and the general patterns of directional root growth typified by a given genotype in unit gravity are recapitulated on orbit, although overall growth patterns on orbit are less uniform. Skewing appears independent of axial orientation on the ISS - suggesting that other tropisms (such as for oxygen and temperature) do not influence skewing. An aspect of the spaceflight environment also retards the rate of early Arabidopsis growth.

Gravity driven and in situ fractional crystallization processes in the Centre Hill complex, Abitibi Subprovince, Canada: Evidence from bilaterally-paired cyclic units

NASA Astrophysics Data System (ADS)

Thériault, R. D.; Fowler, A. D.

1996-12-01

The formation of layers in mafic intrusions has been explained by various processes, making it the subject of much controversy. The concept that layering originates from gravitational settling of crystals has been superseded in recent years by models involving in situ fractional crystallization. Here we present evidence from the Centre Hill complex that both processes may be operative simultaneously within the same intrusion. The Centre Hill complex is part of the Munro Lake sill, an Archean layered mafic intrusion emplaced in volcanic rocks of the Abitibi Subprovince. The Centre Hill complex comprises the following lithostratigraphic units: six lower cyclic units of peridotite and clinopyroxenite; a middle unit of leucogabbro; six upper cyclic units of branching-textured gabbro (BTG) and clotted-textured gabbro (CTG), the uppermost of these units being overlain by a marginal zone of fine-grained gabbro. The cyclic units of peridotite/clinopyroxenite and BTG/CTG are interpreted to have formed concurrently through fractional crystallization, associated with periodic replenishment of magma to the chamber. The units of peridotite and clinopyroxenite formed by gravitational accumulation of crystals that grew under the roof. The cyclic units of BTG and CTG formed along the upper margin of the sill by two different mechanisms: (1) layers of BTG crystallized in situ along an inward-growing roof and (2) layers of CTG formed by accumulation of buoyant plagioclase crystals. The layers of BTG are characterized by branching pseudomorphs after fayalite up to 50 cm in length that extend away from the upper margin. The original branching crystals are interpreted to have grown from stagnant intercumulus melt in a high thermal gradient resulting from the injection of new magma to the chamber.

Nom et lumière: enlightenment through nomenclature (the 1996 Kenneth F. Russell Memorial Lecture).

PubMed

Pearn, J

1997-08-01

The classification of living things is both an acknowledgement of biological relationships and an identification of their differences. When Linnaeus, in 1735, published Systema Naturae, he set in place a system of biological classification that saw its apogee in the invention of binomial nomenclature: the description of every living thing being embodied simply in two names, (i.e. a genus and the species within it). Linnaeus built on the work of scientific forebears, of whom Nehemiah Grew (1641-1712) was one of the most influential. Grew was a surgeon-physician whose passionate interest was plant anatomy; his work led to the discovery and documentation of sexual dimorphism in plants. Grew's life and works are a witness to that philosophy which views nature as a continuum, a broad holistic entity in which discoveries in one biological field have ramifications in other areas. Grew allowed his scientific curiosity full rein, manifested the courage to publish his work and possessed the self-discipline to stand by the audit of his peers. Modern biological research and contemporary clinical practice owes much to the enlightenment engendered by the classification and nomenclature that developed from his work.

Sodium inhibited citrate uptake by two of the four strains of Aerobacter (Enterobacter) aerogenes used in these studies, had no effect on one strain, and stimulated citrate uptake by one strain. Two of the four strains grew well anaerobically on citrate in the presence of Na+, one grew poorly, and one grew not at all either in the presence or absence of Na+. Na+ stimulated the aerobic growth of one strain on citrate, increased the total growth but not the rate of growth of one strain, and prolonged the lag phase but not the rate of growth or total growth of two strains. The experimental data reported herein, therefore, indicate that there are appreciable physiological differences among strains of A. aerogenes. PMID:4418533

Hexagonal molybdenum trioxide thin films with good crystallinity and high purity have been fabricated by the liquid phase deposition (LPD) technique using molybdic acid (H{sub 2}MoO{sub 4}) dissolved in 2.82% hydrofluoric acid (HF) and H{sub 3}BO{sub 3} as precursors. The crystal was found to belong to a hexagonal hydrate system MoO{sub 3}.nH{sub 2}O (napprox0.56). The unit cell lattice parameters are a=10.651 A, c=3.725 A and V=365.997 A{sup 3}. Scanning electron microscope (SEM) images of the as-deposited samples showed well-shaped hexagonal rods nuclei that grew and where the amount increased with increase in reaction time. X-ray photon electron spectroscopy (XPS) spectramore » showed a Gaussian shape of the doublet of Mo 3d core level, indicating the presence of Mo{sup 6+} oxidation state in the deposited films. The deposited films exhibited an electrochromic behavior by lithium intercalation and deintercalation, which resulted in coloration and bleaching of the film. Upon dehydration at about 450 deg. C, the hexagonal MoO{sub 3}.nH{sub 2}O was transformed into the thermodynamically stable orthorhombic phase. - Abstract: SEM photograph of typical h-MoO{sub 3}.nH{sub 2}O thin film nuclei obtained after 36 h at 40 deg.

Recent seasonal variations in arid landscape cover and aeolian sand mobility, Navajo Nation, southwestern U.S.

The socioeconomic impacts of climate change pose problems not only in devel- oping countries but also to residents of arid lands in the United States among marginalized societies with limited economic means. In the Navajo Nation, warming temperatures and recent drought have increased aeolian sediment mobility such that large, migrating sand dunes affect grazing lands, housing, and road access. Dust derived from this region also affects albedo and longevity of the Rocky Mountains snowpack, located downwind. We present initial results from a study that monitors sand transport and vegetation within a 0.2 km2 site in the Navajo lands, measuring the effects of drought on landscape stability since 2009. Sand mobility decreased substantially as 1 year with near-normal monsoon rainfall (2010) somewhat abated a decade-long drought, temporarily doubling vegetation cover. Vegetation that grew during 2010, with adequate rain, died off rapidly during dry conditions in 2011. Short-term increases in rainfall that promote annual, but not perennial, plant growth will not improve landscape stability in the long term. Climate projections suggest that a warmer, drier climate and potentially enhanced sediment supply from ephem- eral washes will further increase aeolian sand transport and dune activity, worsening the present challenges to people living in this region. Connections among climate, vegetation, and aeolian sediment erodibility in this region are highly relevant to other areas of the world with similar environmental problems.

Gender Differences in Cognition among Older Adults in China.

2012-01-01

In this paper, we model gender differences in cognitive ability in China using a new sample of middle-aged and older Chinese respondents. Modeled after the American Health and Retirement Study (HRS), the CHARLS Pilot survey respondents are 45 years and older in two quite distinct provinces-Zhejiang, a high-growth industrialized province on the East Coast, and Gansu, a largely agricultural and poor province in the West-in a sense new and old China. Our cognition measures proxy for two different dimensions of adult cognition-episodic memory and intact mental status. On both measures, Chinese women score much lower than do Chinese men, a gender difference that grows among older Chinese cohorts. We relate both these cognition scores to schooling, urban residence, family and community levels of economic resources, and height. We find that cognition is more closely related to mean community resources than to family resources, especially for women, suggesting that in traditional poor Chinese communities there are strong economic incentives to favor boys at the expense of girls. We also find that these gender differences in cognitive ability have been steadily decreasing across birth cohorts as the economy of China grew rapidly. Among cohorts of young adults in China, there is no longer any gender disparity in cognitive ability. This parallels the situation in the United States where cognition scores of adult women actually exceed those of adult men.

Hispanic ethnicity is associated with a reduced risk of fatal falls in the elderly despite lower socioeconomic standing. The factors responsible for this "Hispanic paradox" are unknown. We hypothesized that age and gender would modify this relationship and that the association would be accentuated in a community with prominent Hispanic culture. The number of fatal falls in a 3-year period in the United States (US) and in Miami-Dade County, Florida (MDC) were obtained through the CDC's WISQARS database and the Florida Office of Vital Statistics. US Census Bureau data were used to define the total at-risk populations by age group and gender. Age group- and gender-specific ratios of the risk of fatal fall in Hispanic to white non-Hispanic individuals were calculated. In the US and MDC, Hispanic ethnicity was associated with a reduced risk of fatal fall across all age and gender subgroups. In the US, the risk reduction associated with Hispanic ethnicity grew from 11% and 23% in 65- to 74-year-old men and women, respectively, to 43% for both men and women over 84-years-old. This relationship was stronger in MDC than nationally in five of the six age and gender subgroups examined. Older individuals, women, and residents of communities with prominent Hispanic culture have the greatest reduction in fatal fall risk associated with Hispanic ethnicity.

Snake fungal disease (SFD) is an emerging disease of conservation concern in eastern North America. Ophidiomyces ophiodiicola, the causative agent of SFD, has been isolated from over 30 species of wild snakes from six families in North America. Whilst O. ophiodiicola has been isolated from captive snakes outside North America, the pathogen has not been reported from wild snakes elsewhere. We screened 33 carcasses and 303 moulted skins from wild snakes collected from 2010–2016 in Great Britain and the Czech Republic for the presence of macroscopic skin lesions and O. ophiodiicola. The fungus was detected using real-time PCR in 26 (8.6%) specimens across the period of collection. Follow up culture and histopathologic analyses confirmed that both O. ophiodiicola and SFD occur in wild European snakes. Although skin lesions were mild in most cases, in some snakes they were severe and were considered likely to have contributed to mortality. Culture characterisations demonstrated that European isolates grew more slowly than those from the United States, and phylogenetic analyses indicated that isolates from European wild snakes reside in a clade distinct from the North American isolates examined. These genetic and phenotypic differences indicate that the European isolates represent novel strains of O. ophiodiicola. Further work is required to understand the individual and population level impact of this pathogen in Europe.

Air travel is up, airports are expanding, and communities are bearing the consequences. Louie Yeldell moved into his house thirty-two years ago. Now, at the age of seventy, he is ready to sell. But there are no takers. He lives on the eastern edge of Memphis-Shelby County International Airport, the busiest cargo airport in the United States. When suburban communities like Yeldell`s Oakhaven sprang up near airport property several decades ago, operations were much smaller, so the noise and the fumes presented no problem. Then, the airport grew. In the mid-1980s, Memphis-Shelby County International became a Northwest hub, and Federalmore » Express increased operations there dramatically. As a result, Yeldell says, the situation has become unbearable. There`s the stench of fuel that wafts through the neighborhood when the wind is right, and sometimes burns his lungs when he steps outside to pick up the morning paper. There`s the black soot that is deposited on his car. And worst of all, there`s the noise. It keeps Yeldell and his wife sealed inside behind closed windows and doors during the day, and wakes them up at night. This article details the compounded problems of increased air travel in the US and how the current laws do and don`t help abatement of the problems. 6 figs.« less

United States (US) and worldwide telestroke programs frequently focus only on emergency room hyper-acute stroke management. This article describes a comprehensive, telemedicine-enabled, stroke care delivery system that combines "drip and ship" and "drip and keep" models with a comprehensive stroke center primary hub at Ochsner Medical Center in New Orleans, advanced stroke-capable regional hubs, and geographically-aligned, "stroke-ready" spokes. The primary hub provides vascular neurology expertise via telemedicine and monitors care for patients remaining at regional hubs and spokes using a multidisciplinary team approach. By 2014, primary hub telestroke consults grew to ≈1000/year with 16 min average door to consult initiation and 20 min to completion, and 29% of ischemic stroke patients received recombinant tissue-type plasminogen activator (rtPA), increasing 275%. Most patients remained in hospitals close to home, but neurointensive care and interventional procedures were common reasons for primary hub transfer. Given the time sensitivity and expert consultation needed for complex acute stroke care delivery paradigms, telestroke programs are effective for fulfilling unmet care needs. Combining drip and ship and drip and keep management allows more patients to stay "local," limiting primary hub transfer unless more advanced services are required. Post admission telestroke management at spokes increases personnel efficiency and can positively impact stroke outcomes.

Latitudinal variation in cold hardiness in introduced Tamarix and native Populus

To investigate the evolution of clinal variation in an invasive plant, we compared cold hardiness in the introduced saltcedar (Tamarix ramosissima, Tamarix chinensis, and hybrids) and the native plains cottonwood (Populus deltoidessubsp. monilifera). In a shadehouse in Colorado (41°N), we grew plants collected along a latitudinal gradient in the central United States (29–48°N). On 17 occasions between September 2005 and June 2006, we determined killing temperatures using freeze-induced electrolyte leakage and direct observation. In midwinter, cottonwood survived cooling to −70°C, while saltcedar was killed at −33 to −47°C. Frost sensitivity, therefore, may limit northward expansion of saltcedar in North America. Both species demonstrated inherited latitudinal variation in cold hardiness. For example, from September through January killing temperatures for saltcedar from 29.18°N were 5–21°C higher than those for saltcedar from 47.60°N, and on September 26 and October 11, killing temperatures for cottonwood from 33.06°N were >43°C higher than those for cottonwood from 47.60°N. Analysis of nine microsatellite loci showed that southern saltcedars are more closely related to T. chinensis while northern plants are more closely related to T. ramosissima. Hybridization may have introduced the genetic variability necessary for rapid evolution of the cline in saltcedar cold hardiness.

Human genetics after the bomb: Archives, clinics, proving grounds and board rooms.

In this paper I track the history of post-1945 human genetics and genomics emphasizing the importance of ideas about risk to the scientific study and medical management of human heredity. Drawing on my own scholarship as it is refracted through important new work by other scholars both junior and senior, I explore how radiation risk and then later disease risk mattered to the development of genetics and genomics, particularly in the United States. In this context I excavate one of the central ironies of post-war human genetics: while studies of DNA as the origin and cause of diseases have been lavishly supported by public institutions and private investment around the world, the day-to-day labor of intensive clinical innovation has played a far more important role in the actual human experience of genetic disease and genetic risk for affected families. This has implications for the archival record, where clinical interactions are less readily accessible to historians. This paper then suggests that modern genomics grew out of radiation risk; that it was and remains a risk assessment science; that it is temporally embedded as a form of both prediction and historical reconstruction; and that it has become a big business focused more on risk and prediction (which can be readily marketed) than on effective clinical intervention.

Dilution cultures of 30 samples of ground black pepper yielded an average of 39,000 colonies of fungi per g, with a range of 1,700 to 310,000 per g. Total numbers of colonies of bacteria from 11 samples averaged 194,000,000 per g, with a range from 8,300,000 to 704,000,000 per g. A variety of fungi grew from nearly all surface-disinfected whole peppercorns that were cultured. Thirteen samples of ground red pepper from the United States yielded an average of 1,600 colonies of storage fungi per g and an equal number of other fungi; five samples from India yielded an average of 78,900 colonies of storage fungi per g and 169,400 colonies of other fungi per g. Among the fungi from both black and red pepper were Aspergillus flavus and A. ochraceus, some isolates of which, when grown for 8 to 10 days on moist autoclaved corn and fed to white rats or to 2-day-old Pekin ducklings, were rapidly lethal to them. Aflatoxin B(1) was isolated from one of the samples of corn on which A. flavus from black pepper was grown. Among the bacteria isolated from ground black pepper were Escherichia coli, E. freudii, Serratia sp., Klebsiella sp., Bacillus sp., Staphylococcus sp., and Streptococcus sp. No cultures of Shigella or Salmonella were found.

Citizen science projects, which engage non-professional scientists in one or more stages of scientific research, have been gaining popularity; yet maintaining participants’ activity level over time remains a challenge. The objective of this study was to evaluate the potential for a short-term, focused campaign to increase participant activity in a national-scale citizen science program. The campaign that we implemented was designed to answer a compelling scientific question. We invited participants in the phenology-observing program, Nature’s Notebook, to track trees throughout the spring of 2012, to ascertain whether the season arrived as early as the anomalous spring of 2010. Consisting of a series of six electronic newsletters and costing our office slightly more than 1 week of staff resources, our effort was successful; compared with previous years, the number of observations collected in the region where the campaign was run increased by 184%, the number of participants submitting observations increased by 116%, and the number of trees registered increased by 110%. In comparison, these respective metrics grew by 25, 55, and 44%, over previous years, in the southeastern quadrant of the United States, where no such campaign was carried out. The campaign approach we describe here is a model that could be adapted by a wide variety of programs to increase engagement and thereby positively influence participant retention.

Medical care employment in the United States, 1968 to 1993: The importance of health sector jobs for African Americans and women.

1996-04-01

The purpose of this study was to elucidate the social and economic impact of health sector employment. US medical care employment was analyzed for each year between 1968 and 1993, with data from the March Current Population Survey. Between 1968 and 1993, medical care employment grew from 4.32 million to 11.40 million persons, accounting for 5.7% of all jobs in 1968 and 8.4% in 1993. Today, one seventh of employed women work in medical care; they hold 78% of medical care jobs. One fifth of all employed African-American women work in medical care. African-Americans hold 15.5% of jobs in the health sector: they hold 24.1% of the jobs in nursing homes, 15.9% of the jobs in hospitals, but only 5.6% of the jobs in practitioners' offices. Hispanics constitute 6.4% of medical care employees. Real wages rose 25% to 50% between 1968 and 1993 for most health occupations. Wages of registered nurses rose 86%; physicians' incomes rose 22%. Wages of nursing home workers were far lower than those of comparable hospital workers, and the gap has widened. In 1993, 11.7% of all medical care workers lacked health insurance and 597 000 lived in poverty. Hospital cuts and the continuing neglect of long-term care exacerbate unemployment and poverty among women and African Americans.

Howard Wilcox Haggard and the Institutionalization of Modern Alcohol Studies.

PubMed

Allred, Nicholas; Bejarano, William; Ward, Judit

2017-03-01

This biographical sketch and accompanying bibliography provide a new look at Howard Wilcox Haggard, M.D., Ph.D., whose career highlights the consolidation of alcohol studies as a field in twentieth-century America. The article relies in large part on the works of Haggard assembled for the bibliography project, supplemented by published and unpublished documents and records from collections at Rutgers University. Haggard began his career in respiratory physiology, influenced by his work on chemical weapons for the Army during the First World War. As his reputation grew, he moved into anesthesiology and supplemented his research with textbooks and popular science bestsellers. Haggard moved into the burgeoning field of alcohol studies after the repeal of National Prohibition and, in 1940, became the inaugural editor and president of the corporation of the Quarterly Journal of Studies on Alcohol, now the Journal of Studies on Alcohol and Drugs. Under the aegis of the Yale Laboratory for Applied Physiology, he also assembled and oversaw what would become the Center of Alcohol Studies. Haggard died in 1959, his legacy established as a central figure in the 20th-century transformation of alcohol studies in the United States. A prolific researcher with a talent for tapping into the public zeitgeist, Haggard helped provide the institutional infrastructure, academic credibility, and broad audience that made the renaissance of alcohol studies in post-Prohibition America possible.

Evidence of Urban-Induced Precipitation Variability in Arid Climate Regimes

Shepherd, J. Marshall

2005-01-01

Water is essential to life in the Earth system. The water cycle components that sustain life are becoming more scarce and polluted. The most recent (1999-2004) drought experienced in the southwestern United States is the seventh worst in the approximately 500-year proxy tree-ring record. As a result, many regions contemplated drought emergencies in which severe water restrictions are implemented. Though larger weather and climate processes likely control drought processes, there is increasing evidence that anthropogenic or human-related activities can significantly alter precipitation processes. Urbanization is an example of anthropogenic forcing. Recent studies continue to provide evidence that urban environments can modify or induce precipitation under a specific set of conditions. Arid and semi-arid regions of the southwestern United States and other parts of the world are rapidly developing and placing greater demands on the environmental system. In the past fifty years, Phoenix has expanded from a predominantly agricultural center to an urbanized region with extent 700 percent larger than its size in the middle of the twentieth century. Riyadh's population grew from about a half million people in 1972 to almost two million by 2000. Saudi Arabia experienced urbanization later than many other countries; in the early 1970s its urban-rural ratio was still about 1:3. By 1990 the ratio had reversed to about 3:l. In the mid-1970s Riyadh's population was increasing by about 10 percent a year. Irrigation also significantly increased between 1972 and 1990 southeast of Riyadh. The study employs a 108-year precipitation historical data record, global climate observing network observations and satellite data to identify possible anomalies in rainfall in and around two major arid urban areas, Phoenix, Arizona and Riyadh, Saudi Arabia. It provides statistically sound evidence that rainfall distribution and magnitude is statistically different in post-urban than in pre-urban (1900-1950) Phoenix. The study hypothesis that a complex interaction between the city landscape, irrigated lands, and nearby mountains have created preferred regions for rainfall development. The study also provides early evidence that rapidly urbanizing parts of the arid Middle East may also be experiencing different precipitation regimes in response to urbanization and irrigation.

Economic and Political Influence on Tobacco Tax Rates: A Nationwide Analysis of 31 Years of State Data

Ribisl, Kurt M.; Perreira, Krista M.

2014-01-01

Objectives. We evaluated state-level characteristics associated with cigarette excise taxes before and after the Master Settlement Agreement (MSA). Methods. We gathered annual cigarette excise tax rates for all US states and the District of Columbia, between 1981 and 2011, and matched each state–year tax rate with economic, political, attitudinal, and demographic characteristics, creating a data set of 1581 observations. We used panel data regression techniques to assess relationships between key characteristics and state cigarette excise tax levels. Results. Cigarette excise tax rates grew at more than 6 times the rate of inflation between 1981 and 2011; growth varied by time period and region. We found strong negative associations between Republican Party control of state legislatures and governors’ offices and state cigarette tax rates. Tobacco production, citizens’ attitudes toward taxes and tobacco control, and cigarette tax rates in neighboring states were significantly associated with cigarette tax rates. We found no association between unemployment and tax rates. Conclusions. Future excise tax growth rate may depend more on the political leanings of state legislators, and the attitudes of the people they represent, than on economic circumstances. PMID:24328667

Citizen Science: Dune Restoration with Sea Oats by Junior Friends of MacArthur Beach State Park

NASA Astrophysics Data System (ADS)

Allen, S.

2016-12-01

As a crucial part of the dune ecosystem, Sea Oats are a protected species in Florida. They provide excellent habitat for small birds and mammals and prevent dune erosion with their fibrous roots.Citizen science is a research and education tool that involves everyday people in real and meaningful forms of science. My volunteer group, Junior friends of Macarthur Beach State Park, used citizen science to restore dunes by growing and planting Sea Oats. Junior friends is a group of 6-12th grade students whose purpose is to support the park through monthly activities and special events. Junior Friends asked,what is the best way to germinate/grow/and plant Sea Oats to renourish the beach dune. Specifically, what planting medium is most conducive for maximizing growth of Sea Oats? We tested three scenarios: 100% potting soil, 100% sand from the beach, 50% sand-50% potting soil mixture.Using harvested Sea Oat seeds from Macarthur Beach State Park, we separated the seeds from their casings, known as spiklets. We then monitored the plant's weekly over the course of 14 weeks and charted their growth. All the seeds had similar growth rates, but the seeds that grew in 100% potting soil consistently grew the tallest. The second tallest Sea Oats were 100% sand; the 50% sand-50% potting soil mixture produced the least amount of growth. When seedlings reached their desired growth of 6-8 inches and established a root ball, we planted the Sea Oats on the dune for restoration. After planting them,we monitored the growth of the Sea Oats on the MacArthur Beach dune throughout the rest of the year, charting the height of the planted Sea Oats. Using Citizen science we had meaningful data that helped us have a better understanding of restoring Sea Oats on Florida dunes and will help further future restorations.

Characterization of Carbonate Crust from Deep-sea Methane Seeps on the Northern US Atlantic Margin.

2017-12-01

Authigenic carbonate minerals widely occur at the seafloor as carbonate crusts and are often directly linked to microbial activity, about which promotion of carbonate crystal growth and geochemistry are not entirely understood. To evaluate a potential metabolic contribution, studies were conducted on carbonate crust collected from a methane seep and on precipitation experiments which produced inorganic aragonite crystallized at high pressure. Among the samples collected during a NSF sponsored cruise to the North Atlantic Continental Margin of the United States (off of New England) in July-August 2016, we analyzed one carbonate crust sample (AD4835 BB-4522) collected at 39.805860; -69.592593 and at a depth of 1419.6 m. In this crust sample, two textural types of aragonite were identified: 1) groundmass consisting of fine grey crystals (<1 µm in size); 2) veins consisting of white acicular crystals (up to 100 µm in width). In addition, large equant quartz crystals (>100 µm, 24.9 wt%), feldspar (5.6 wt%), and dolomite (3.6 wt%), and trace amount of troilite were identified using XRD, SEM, and optical microscopy. The sample was cut into slabs parallel to crust growth assuming the crust grew in a downward direction. Concentrations of Na, Mg, Al, Si, S, K, Ca, Mn, Fe, Sr, Zr, Ba, and U were measured in the direction parallel to growth of the crust using LA-ICP-MS. Proportions of Si, Al, (Na+K), Mg, S, and Fe in the groundmass suggest the occurrence of sub-micron inclusions of alkali feldspar, and potentially pyroxene, Fe oxide, and Fe sulfide, which were impossible to avoid with the instrument's spatial resolution. The occurrence of micro non-carbonate inclusions causes high elemental concentrations compared to the values expected for aragonite crystallized from seawater. White aragonite acicular crystals were free of silicate and sulfide inclusions, and therefore, yielded lower concentrations of all measured elements except Sr compared to the groundmass. Analyzed Mg and Sr are consistent with published data for deep-sea corals. Also, Sr is similar to experimental data on inorganic aragonite. Mg/Ca, Sr/Ca, Ba/Ca, and U/Ca of the fluid from which acicular aragonite grew were calculated based on partition coefficients from inorganic aragonite precipitated at 100 bars.

The United States and Japan pursue a common agenda.

PubMed

Westley, S B

1996-10-01

In July 1993, the US and Japan formed the "Common Agenda for Cooperation in Global Perspective," an economic alliance to promote health and human development, respond to challenges to global stability, protect the global environment, advance science and technology, and foster exchanges for mutual understanding. A Global Issues Initiative (GII) has been created within this framework to support family planning, HIV and sexually transmitted disease prevention and control efforts, maternal and child health, primary health care, and women's empowerment. Participation in the GII has led Japan to more than double the technical assistance it provides and to broaden its geographic focus from Asia to the entire developing world. The US continues to fund population and health programs in more than 50 countries. The Common Agenda grew out of a US-Japan development assistance policy consultation dialogue known as the "Honolulu process," which sought ways to promote mutual understanding among US and Japanese development assistance personnel (through international internships) and nongovernmental organizations and to identify specific areas for joint or parallel development projects. Cooperative activities are underway in the Philippines, Indonesia, Bangladesh, India, Ghana, Peru, Guatemala, Mexico, and Jamaica. Joint project evaluations have also taken place in Zambia and Ghana. The Common Agenda's Children's Health Initiative has supported such initiatives as achieving child immunization in the Newly Independent States and joint efforts to eradicate polio and micronutrient disorders. The Women in Development initiative enhances girls' education and assists women engaged in small-scale enterprises. After initial difficulties in agreeing on joint strategies, the Common Agenda has been an "overwhelmingly positive" experience with the potential to meet critical challenges, because Japan and the US account for 40% of all development assistance worldwide.

The Pharmaceutical Benefits Scheme 2003–2004

PubMed Central

Harvey, Ken J

2005-01-01

The Pharmaceutical Benefits Scheme (PBS) grew by 8% in 2003–04; a slower rate than the 12.0% pa average growth over the last decade. Nevertheless, the sustainability of the Scheme remained an ongoing concern given an aging population and the continued introduction of useful (but increasingly expensive) new medicines. There was also concern that the Australia-United States Free Trade Agreement could place further pressure on the Scheme. In 2003, as in 2002, the government proposed a 27% increase in PBS patient co-payments and safety-net thresholds in order to transfer more of the cost of the PBS from the government to consumers. While this measure was initially blocked by the Senate, the forthcoming election resulted in the Labor Party eventually supporting this policy. Recommendations of the Pharmaceutical Benefits Advisory Committee to list, not list or defer a decision to list a medicine on the PBS were made publicly available for the first time and the full cost of PBS medicines appeared on medicine labels if the price was greater than the co-payment. Pharmaceutical reform in Victorian public hospitals designed to minimise PBS cost-shifting was evaluated and extended to other States and Territories. Programs promoting the quality use of medicines were further developed coordinated by the National Prescribing Service, Australian Divisions of General Practice and the Pharmacy Guild of Australia. The extensive uptake of computerised prescribing software by GPs produced benefits but also problems. The latter included pharmaceutical promotion occurring at the time of prescribing, failure to incorporate key sources of objective therapeutic information in the software and gross variation in the ability of various programs to detect important drug-drug interactions. These issues remain to be tackled. PMID:15679896

Health care expenditures for children with autism spectrum disorders in Medicaid.

PubMed

Wang, Li; Leslie, Douglas L

2010-11-01

To study trends in health care expenditures associated with autism spectrum disorders (ASDs) in state Medicaid programs. Using Medicaid data from 42 states from 2000 to 2003, patients aged 17 years and under who were continuously enrolled in fee-for-service Medicaid were studied. Patients with claims related to autistic disorder (autism) were identified, as were patients with claims for any ASD other than autism. Total expenditures per treated patient consisted of Medicaid reimbursements from inpatient, outpatient, and long-term care and prescription drugs. Inflation-adjusted expenditures were compared over time and with expenditures associated with other mental health disorders. A total of 2,184,677 children were diagnosed with some type of mental disorder during the study period. Of these children, 69,542 had an ASD, with 49,921 having autism and the rest having another ASD. Mean total health care expenditures per child with ASD were $22,079 in 2000 (in 2003 US dollars), and rose by 3.1% to $22,772 in 2003. The treated prevalence of autism per 10,000 covered lives rose by 32.2% from 40.6 to 53.6, the highest rate of increase among all mental disorders. Total health care expenditures for ASDs per 10,000 covered lives grew by 32.8% from $1,270,435 in 2000 (in 2003 dollars) to $1,686,938 in 2003. Medicaid-reimbursed health care expenditures for ASD were quite substantial. Although the per patient expenditures grew slightly over time, the large increase in treated prevalence caused a considerable rise in total ASD-associated health care expenditures.

In-situ growth of calcite at Devils Hole, Nevada: Comparison of field and laboratory rates to a 500,000 year record of near-equilibrium calcite growth

Plummer, Niel; Busenberg, E.; Riggs, A.C.

2000-01-01

Calcite grew continuously for 500,000 years on the submerged walls of an open fault plane (Devils Hole) in southern Nevada, U.S.A. at rates of 0.3 to 1.3 mm/ka, but ceased growing approximately 60,000 years ago, even though the fault plane remained open and was continuously submerged. The maximum initial in-situ growth rate on pre-weighed crystals of Iceland spar placed in Devils Hole (calcite saturation index, SI, is 0.16 to 0.21 at 33.7??C) for growth periods of 0.75 to 4.5 years was 0.22 mm/ka. Calcite growth on seed crystals slowed or ceased following initial contact with Devils Hole groundwater. Growth rates measured in synthetic Ca-HCO3 solutions at 34??C, CO2 partial pressures of 0.101, 0.0156 (similar to Devils Hole groundwater) and 0.00102 atm, and SI values of 0.2 to 1.9 were nearly independent of P(CO)(2), decreased with decreasing saturation state, and extrapolated through the historical Devils Hole rate. The results show that calcite growth rate is highly sensitive to saturation state near equilibrium. A calcite crystal retrieved from Devils Hole, and used without further treatment of its surface, grew in synthetic Devils Hole groundwater when the saturation index was raised nearly 10-fold that of Devils Hole water, but the rate was only 1/4 that of fresh laboratory crystals that had not contacted Devils Hole water. Apparently, inhibiting processes that halted calcite growth in Devils Hole 60,000 years ago continue today.

Social disorder and diagnostic order: the US Mental Hygiene Movement, the Midtown Manhattan study and the development of psychiatric epidemiology in the 20th century.

PubMed

March, Dana; Oppenheimer, Gerald M

2014-08-01

Recent scholarship regarding psychiatric epidemiology has focused on shifting notions of mental disorders. In psychiatric epidemiology in the last decades of the 20th century and the first decade of the 21st century, mental disorders have been perceived and treated largely as discrete categories denoting an individual's mental functioning as either pathological or normal. In the USA, this grew partly out of evolving modern epidemiological work responding to the State's commitment to measure the national social and economic burdens of psychiatric disorders and subsequently to determine the need for mental health services and to survey these needs over time. Notably absent in these decades have been environmentally oriented approaches to cultivating normal, healthy mental states, approaches initially present after World War II. We focus here on a set of community studies conducted in the 1950s, particularly the Midtown Manhattan study, which grew out of a holistic conception of mental health that depended on social context and had a strong historical affiliation with: the Mental Hygiene Movement and the philosophy of its founder, Adolf Meyer; the epidemiological formation of field studies and population surveys beginning early in the 20th century, often with a health policy agenda; the recognition of increasing chronic disease in the USA; and the radical change in orientation within psychiatry around World War II. We place the Midtown Manhattan study in historical context--a complex narrative of social institutions, professional formation and scientific norms in psychiatry and epidemiology, and social welfare theory that begins during the Progressive era (1890-1920) in the USA. © The Author 2014; all rights reserved.

To analyze whether the changes observed in the level and distribution of resources for maternal health and family planning (MHFP) programs from 2003 to 2012 were consistent with the financial goals of the related policies. A longitudinal descriptive analysis of the Mexican Reproductive Health Subaccounts 2003-2012 was performed by financing scheme and health function. Financing schemes included social security, government schemes, household out-of-pocket (OOP) payments, and private insurance plans. Functions were preventive care, including family planning, antenatal and puerperium health services, normal and cesarean deliveries, and treatment of complications. Changes in the financial imbalance indicators covered by MHFP policy were tracked: (a) public and OOP expenditures as percentages of total MHFP spending; (b) public expenditure per woman of reproductive age (WoRA, 15-49 years) by financing scheme; (c) public expenditure on treating complications as a percentage of preventive care; and (d) public expenditure on WoRA at state level. Statistical analyses of trends and distributions were performed. Public expenditure on government schemes grew by approximately 300%, and the financial imbalance between populations covered by social security and government schemes decreased. The financial burden on households declined, particularly among households without social security. Expenditure on preventive care grew by 16%, narrowing the financing gap between treatment of complications and preventive care. Finally, public expenditure per WoRA for government schemes nearly doubled at the state level, although considerable disparities persist. Changes in the level and distribution of MHFP funding from 2003 to 2012 were consistent with the relevant policy goals. However, improving efficiency requires further analysis to ascertain the impact of investments on health outcomes. This, in turn, will require better financial data systems as a precondition for improving the monitoring and accountability functions in Mexico.

1981-01-01

Average 4-year-height of 199 hybrid poplar clones ranged from 5.1 to 26.0 feet in Pennsylvania and 5.6 to 22.7 feet in Maryland. Several rapid-growing clones grew well at both locations, but height growth was affected by interactions of clones and location. The clones that grew best on both sites averaged 4 to 6 feet of height growth per year.

2016-01-01

The molar tooth of children and young adults is a common site for chronic hyperplastic pulpitis (pulp polyp). It rarely occurs in middle aged adults. This condition is usually characterized by extensive involvement of the pulp, dictating the extraction of involved tooth. Extraction of permanent molars can lead to transient or permanent malocclusion, aesthetic, phonetic and functional problems. Here we report a case of pulp polyp in mandibular first molar of a 33-year-old woman that grew into the carious cavity. The aim of this case report is to describe the diagnosis of a chronic hyperplastic pulpitis involving the permanent molar as well as to describe its management in order to preserve them as a functional unit of the dentition.

Ages of subsurface stratigraphic intervals in the Quaternary of Enewetak Atoll, Marshall Islands

USGS Publications Warehouse

Szabo, B. J.; Tracey, J.I.; Goter, E.R.

1985-01-01

Drill cores of Enewetak Atoll, Marshall Islands, reveal six stratigraphic intervals, numbered in downward sequence, which represent vertical coral growth during Quaternary interglaciations. Radiocarbon dates indicate that the Holocene sea transgressed the emergent reef platform by about 8000 yr B.P. The reef grew rapidly upward (about 5 to 10 mm/yr) until about 6500 yr B.P. Afterward vertical growth slowed to about 0.5 mm/yr, then lateral development became dominant during the last several thousand years. The second interval is dated at 131,000 ?? 3000 yr B.P. by uranium series. This unit correlates with oxygen-isotope substage 5e and with terrace VIIa of Huon Peninsula, New Guinea, and of Main Reef-2 terrace at Atauro Island. The third interval is not dated because corals were recrystallized and it is tentatively correlated with either oxygen-isotope stages 7 or 9. The age of the fourth interval is estimated at 454,000 ?? 100,000 yr B.P. from measured 234U 238U activity ratios. This unit is correlated with either oxygen-isotope stage 9, 11, or 13. ?? 1985.

BACTERIAL CONTAMINATION OF STETHOSCOPES

Bukharie, Huda A.; Al-Zahrani, Hussain; Rubaish, Abdullah M.; Abdulmohsen, Mohammed F.

2004-01-01

Background: A stethoscope, an essential tool of the medical profession, can become a source of nosocomial infection. Objective: To determine the frequency of bacterial contamination of stethoscopes as well as the practices used for cleaning them. Methods: Cultures were taken from 100 stethoscopes used by different medical personnel in different hospital services. The stethoscopes were collected while the staff filled in a questionnaire. Results: Thirty (30%) out of the 100 stethoscopes surveyed were contaminated with microorganisms. The majority of organisms isolated were gram-positive bacteria (gram positive bacilli 12%, gram-negative bacteria 9%, gram-positive cocci 9%). None of the stethoscopes grew methicillin-resistant staphylococcus aureus. Overall, 21% of the health personnel cleaned their stethoscopes daily, 47% weekly, and 32% yearly. None of the health care workers cleaned their stethoscopes after every patient. Nurses cleaned their stethoscopes more often than physicians and medical students. Conclusion: Stethoscopes may be important in the spread of infectious agents. Their regular disinfection after use on each patient should be considered, particularly in such areas of the hospital, as the critical care units, and oncology units which house many patients with antibiotic-resistant organisms.

Advanced degrees in astronautical engineering for the space industry

NASA Astrophysics Data System (ADS)

Gruntman, Mike

2014-10-01

Ten years ago in the summer of 2004, the University of Southern California established a new unique academic unit focused on space engineering. Initially known as the Astronautics and Space Technology Division, the unit operated from day one as an independent academic department, successfully introduced the full set of degrees in Astronautical Engineering, and was formally renamed the Department of Astronautical Engineering in 2010. The largest component of Department's educational programs has been and continues to be its flagship Master of Science program, specifically focused on meeting engineering workforce development needs of the space industry and government space research and development centers. The program successfully grew from a specialization in astronautics developed in mid-1990s and expanded into a large nationally-visible program. In addition to on-campus full-time students, it reaches many working students on-line through distance education. This article reviews the origins of the Master's degree program and its current status and accomplishments; outlines the program structure, academic focus, student composition, and enrollment dynamics; and discusses lessons learned and future challenges.

Acclimation of isoprene emission and photosynthesis to growth temperature in hybrid aspen: resolving structural and physiological controls

PubMed Central

Rasulov, Bahtijor; Bichele, Irina; Hüve, Katja; Vislap, Vivian; Niinemets, Ülo

2018-01-01

Acclimation of foliage to growth temperature involves both structural and physiological modifications, but the relative importance of these two mechanisms of acclimation is poorly known, especially for isoprene emission responses. We grew hybrid aspen (Populus tremula x P. tremuloides) under control (day/night temperature of 25/20 °C) and high temperature conditions (35/27 °C) to gain insight into the structural and physiological acclimation controls. Growth at high temperature resulted in larger and thinner leaves with smaller and more densely packed chloroplasts and with lower leaf dry mass per area (MA). High growth temperature also led to lower photosynthetic and respiration rates, isoprene emission rate and leaf pigment content and isoprene substrate dimethylallyl diphosphate pool size per unit area, but to greater stomatal conductance. However, the declining characteristics were similar when expressed per unit dry mass, indicating that the area-based differences were primarily driven by MA. Acclimation to high temperature further increased heat stability of photosynthesis, and increased activation energies for isoprene emission and isoprene synthase rate constant. This study demonstrates that temperature acclimation of photosynthetic and isoprene emission characteristics per unit leaf area was primarily driven by structural modifications, and we argue that future studies investigating acclimation to growth temperature must consider structural modifications.

Risk Assessment for the Spread of Serratia marcescens Within Dental-Unit Waterline Systems Using Vermamoeba vermiformis.

PubMed

2015-10-01

Vermamoeba vermiformis is associated with the biofilm ecology of dental-unit waterlines (DUWLs). This study investigated whether V. vermiformis is able to act as a vector for potentially pathogenic bacteria and so aid their dispersal within DUWL systems. Clinical dental water was initially examined for Legionella species by inoculating it onto Legionella selective-medium plates. The molecular identity/profile of the glassy colonies obtained indicated none of these isolates were Legionella species. During this work bacterial colonies were identified as a non-pigmented Serratia marcescens. As the water was from a clinical DUWL which had been treated with Alpron™, this prompted the question as to whether S. marcescens had developed resistance to the biocide. Exposure to Alpron™ indicated that this dental biocide was effective, under laboratory conditions, against S. marcescens at up to 1 × 10(8) colony forming units/millilitre (cfu/ml). V. vermiformis was cultured for 8 weeks on cells of S. marcescens and Escherichia coli. Subsequent electron microscopy showed that V. vermiformis grew equally well on S. marcescens and E. coli (P = 0.0001). Failure to detect the presence of S. marcescens within the encysted amoebae suggests that V. vermiformis is unlikely to act as a vector supporting the growth of this newly isolated, nosocomial bacterium.

Beena, V K; Rao, S; Kotian, M; Shivananda, P G

1997-07-01

Fish meal extract bile esculin agar (FMBE) is prepared using Fish meal extract concentrate as the basal substance, for the selective isolation and presumptive identification of B.fragilis group. The efficiency of the medium was evaluated by growing stock cultures of B.fragilis groups as well as inoculating clinical specimens and comparing the results with Bacteroides bile esculin agar (BBE). All the 87 stock cultures of B.fragilis grew on FMBE and BBE. No other anaerobes tested grew on the medium. However 7 out of 65 neomycin resistant aerobes grew on the FMBE. From the 100 clinical samples, 62 strains of B. Fragilis group were recovered on FMBE and BBE, and 53 strains on supplemented BHIBA. The cost effectiveness, selectivity and the ability to detect esculin hydrolysis will enable FMBE as a suitable medium as comparable to that of BBE, if not superior.

2013-01-01

To assess the diagnostic accuracy of histopatho-logic and cytopathologic examination (HCE) of Aspergillus species (spp), we performed an 11-year retrospective review to correlate surgical/cytology cases with a diagnosis of Aspergillus spp with their concurrent fungal culture results. Diagnostic accuracy was defined as the percentage of cases with culture-proven Aspergillus spp divided by the number of cases diagnosed as Aspergillus spp on HCE that had growth on fungal culture. Ninety surgical/cytology cases with concurrent fungal culture were reviewed, 58 of which grew a fungal organism. Of these 58 cases, 45 grew an Aspergillus spp, whereas 13 grew an organism other than Aspergillus spp, including both common (Scedosporium, Fusarium, and Paecilomyces spp) and uncommon mimickers (Trichosporon loubieri), resulting in a diagnostic accuracy of 78%. The low diagnostic accuracy indicates that several fungal organisms can morphologically mimic Aspergillus spp and can only be distinguished by fungal culture and DNA sequencing.

A New Dyslexia Reading Method and Visual Correction Position Method.

Manilla, George T; de Braga, Joe

2017-01-01

Pediatricians and educators may interact daily with several dyslexic patients or students. One dyslexic author accidently developed a personal, effective, corrective reading method. Its effectiveness was evaluated in 3 schools. One school utilized 8 demonstration special education students. Over 3 months, one student grew one third year, 3 grew 1 year, and 4 grew 2 years. In another school, 6 sixth-, seventh-, and eighth-grade classroom teachers followed 45 treated dyslexic students. They all excelled and progressed beyond their classroom peers in 4 months. Using cyclovergence upper gaze, dyslexic reading problems disappeared at one of the Positional Reading Arc positions of 30°, 60°, 90°, 120°, or 150° for 10 dyslexics. Positional Reading Arc on 112 students of the second through eighth grades showed words read per minute, reading errors, and comprehension improved. Dyslexia was visually corrected by use of a new reading method and Positional Reading Arc positions.

Characterization of Sphingomonas isolates from Finnish and Swedish drinking water distribution systems.

Sphingomonas species were commonly isolated from biofilms in drinking water distribution systems in Finland (three water meters) and Sweden (five water taps in different buildings). The Sphingomonas isolates (n = 38) were characterized by chemotaxonomic, physiological and phylogenetic methods. Fifteen isolates were designated to species Sphingomonas aromaticivorans, seven isolates to S. subterranea, two isolates to S. xenophaga and one isolate to S. stygia. Thirteen isolates represented one or more new species of Sphingomonas. Thirty-three isolates out of 38 grew at 5 degrees C on trypticase soy broth agar (TSBA) and may therefore proliferate in the Nordic drinking water pipeline where the temperature typically ranges from 2 to 12 degrees C. Thirty-three isolates out of 38 grew at 37 degrees C on TSBA and 15 isolates also grew on blood agar at 37 degrees C. Considering the potentially pathogenic features of sphingomonas, their presence in drinking water distribution systems may not be desirable.

History of the international societies in health technology assessment: International Society for Technology Assessment in Health Care and Health Technology Assessment International.

PubMed

Banta, David; Jonsson, Egon; Childs, Paul

2009-07-01

The International Society for Technology Assessment in Health Care (ISTAHC) was formed in 1985. It grew out of the increasing awareness of the international dimensions of health technology assessment (HTA) and the need for new communication methods at the international level. The main function of ISTAHC was to present an annual conference, which gradually grew in size, and also to generally improve in quality from to year. ISTAHC overextended itself financially early in the first decade of the 2000s and had to cease its existence. A new society, Health Technology Assessment international (HTAi), based on many of the same ideas and people, grew up beginning in the year 2003. The two societies have played a large role in making the field of HTA visible to people around the world and providing a forum for discussion on the methods and role of HTA.

Water availability and subsidence in California's Central Valley

USGS Publications Warehouse

Faunt, Claudia C.; Sneed, Michelle

2015-01-01

California’s Central Valley covers about 52,000 square kilometers (km2) and is one of the most productive agricultural regions in the world. More than 250 different crops are grown in the broad alluvial filled structural trough, with an estimated value exceeding $20 billion per year (Faunt 2009) (Figure 1). Central Valley agriculture depends on state and federal water systems that divert surface water, predominantly originating from Sierra Nevada snowmelt, to agricultural fields. Because the valley is semi-arid and the availability of surface water varies substantially from year to year, season to season, and from north to south, agriculture, as it grew, developed a reliance on groundwater for irrigation.

This paper reports findings on the state of job-based health insurance in spring 2005 and how it has changed during recent years. Premiums rose 9.2 percent, the first year of single-digit increases since 2000. The percentage of firms offering health benefits has fallen from 69 percent in 2000 to 60 percent in 2005. Cost sharing did not grow appreciably in the past year. Enrollment in preferred provider organizations (PPOs) grew from 55 percent in 2004 to 61 percent in 2005, while enrollment in health maintenance organizations (HMOs) fell from 25 percent to 21 percent of the total.

Plant defense, herbivory, and the growth of Cordia alliodora trees and their symbiotic Azteca ant colonies.

PubMed

Pringle, Elizabeth G; Dirzo, Rodolfo; Gordon, Deborah M

2012-11-01

The effects of herbivory on plant fitness are integrated over a plant's lifetime, mediated by ontogenetic changes in plant defense, tolerance, and herbivore pressure. In symbiotic ant-plant mutualisms, plants provide nesting space and food for ants, and ants defend plants against herbivores. The benefit to the plant of sustaining the growth of symbiotic ant colonies depends on whether defense by the growing ant colony outpaces the plant's growth in defendable area and associated herbivore pressure. These relationships were investigated in the symbiotic mutualism between Cordia alliodora trees and Azteca pittieri ants in a Mexican tropical dry forest. As ant colonies grew, worker production remained constant relative to ant-colony size. As trees grew, leaf production increased relative to tree size. Moreover, larger trees hosted lower densities of ants, suggesting that ant-colony growth did not keep pace with tree growth. On leaves with ants experimentally excluded, herbivory per unit leaf area increased exponentially with tree size, indicating that larger trees experienced higher herbivore pressure per leaf area than smaller trees. Even with ant defense, herbivory increased with tree size. Therefore, although larger trees had larger ant colonies, ant density was lower in larger trees, and the ant colonies did not provide sufficient defense to compensate for the higher herbivore pressure in larger trees. These results suggest that in this system the tree can decrease herbivory by promoting ant-colony growth, i.e., sustaining space and food investment in ants, as long as the tree continues to grow.

The resident microflora of voided midstream urine of healthy controls: standard versus expanded urine culture protocols.

PubMed

Coorevits, L; Heytens, S; Boelens, J; Claeys, G

2017-04-01

The workup and interpretation of urine cultures is not always clear-cut, especially for midstream samples contaminated with commensals. Standard urine culture (SUC) protocols are designed in favor of growth of uropathogens at the expense of commensals. In selected clinical situations, however, it is essential to trace fastidious or new uropathogens by expanding the urine culture conditions (EUC). The aim of our study was to map the microflora in midstream urine specimens from healthy controls by means of EUC, in view of the interpretation of bacterial culture results in symptomatic patients. Midstream urine specimens from 101 healthy controls (86 females and 15 males) were examined using both SUC and EUC. Whilst 73 % of samples examined by SUC showed no growth at 10 3  colony-forming units (CFU)/mL, 91 % of samples examined by EUC grew bacterial species in large numbers (≥10 4  CFU/mL). Asymptomatic bacteriuria, as defined by the European guidelines for urinalysis, was detected in six samples with both protocols. EUC revealed 98 different species, mostly Lactobacillus, Staphylococcus, Streptococcus, and Corynebacterium. None of the samples grew Staphylococcus saprophyticus, Corynebacterium urealyticum, or Aerococcus urinae. Samples from females contained higher bacterial loads and showed higher bacterial diversity compared to males. Midstream urine of healthy controls contains large communities of living bacteria that comprise a resident microflora, only revealed by EUC. Hence, the use of EUC instead of SUC in a routine setting would result in more sensitive but less specific results, requiring critical interpretation. In our view, EUC should be reserved for limited indications.

Carbonate "Clumped" Isotope Determination of Seawater Temperature During the End-Triassic Extinction Event

Stromatolites are laminated sedimentary structures that are commonly thought to be created by cyanobacteria, either through the trapping and binding of sediment, or through metabolically-induced precipitation. However, stromatolite formation is poorly understood. In general, stromatolite abundance was higher in the Proterozoic than the Phanerozoic, but notable increases in stromatolite abundance occur in association with Phanerozoic mass extinction events. Here, we focus on stromatolites from the latest Triassic Cotham Marble (United Kingdom) that are associated with the extinction interval. The end-Triassic mass extinction is coincident with large-scale volcanism in the Central Atlantic Magmatic Province (CAMP) and the associated breakup of Pangea. Some hypothesize that CAMP-associated increases in atmospheric CO2 led to a rise in global temperatures and ocean acidification that caused or enhanced the extinction. In order to quantify the role of climate change with respect to the end-Triassic mass extinction, we applied the carbonate "clumped" isotope paleothermometer to the well-preserved Cotham Marble stromatolites. The stromatolites were deposited in the shallow Tethys Sea, and today occur in several localities across the southwestern UK. The stromatolites alternate on the cm scale between laminated and dendrolitic microstructures and each was microdrilled for clumped isotope analysis. The two microstructures display different temperatures of formation, where the dendrolitic portions apparently grew under cooler conditions than laminated layers, and younger layers grew in cooler conditions than older layers. Our results suggest that temperature fluctuated and potentially trended towards amelioration of the warm temperatures during the deposition of the Cotham Marble.

Describe the supply of inpatient rehabilitation facilities (IRFs) services in 1996 and examine changes between 1996 and 2004, including the impact of the IRF prospective payment system (PPS) in 2002 on organizational trends. Retrospective pre-post design. Freestanding and subprovider (distinct-part units) IRFs. IRFs (N=1424), including 257 freestanding IRFs and 1167 IRF units reported in the Healthcare Cost Report Information System database, from years 1996 to 2004. Not applicable. Number of IRF openings, IRF closures, beds, and inpatient days. The number of IRFs grew from 1037 to 1183 between 1996 and 2001 and grew to 1235 between 2001 and 2004. The likelihood of IRF closures trended lower after PPS, and there was a significant increase in the likelihood of openings when PPS was introduced. For-profit, rural, and small IRFs were more likely to open over the entire period. There was a 12.9% increase in the number of total inpatient days, somewhat less than the 15.7% growth in IRF beds over the period. There was no impact of PPS on beds available but a significant decline in total inpatient days after PPS. Inpatient days rose under the Tax Equity and Fiscal Responsibility Act and declined after 2002. Yet the likelihood of openings and closures did not appear to respond to these changes, perhaps because they were modest compared with changes in local IRF markets. The IRF PPS did little to affect service distribution in less well-served areas, although we did find growth in rural areas. Occupancy rates in 2004 were close to rates at the start of the period (70%). This observation implies that IRFs were implementing strategies to recruit a sufficient number of patients, even though bed numbers were increasing and length of stay was declining. Consequently, policy that limits the potential of IRFs to increase patient admissions, such as the limits on admissions to IRFs of patients with conditions other than those included in the 75% rule, is likely to produce substantial decreases in total inpatient days.

The growth of pulp and paper mills in the US from 1970 to 2000 depended mostly on size and age. Mills grew according to Gibrat’s law, and post-1970 mills grew faster than pre-1971 mills. Mills stopped growing at approximately 22 years of age. But most mills survived beyond that, thus growth was not necessary for survival, but characteristic of the early phase of the...

In this cross-sectional study, mycobacteria specimens from 189 tuberculosis (TB) patients living in an urban area in Brazil were characterised from 2008-2010 using phenotypic and molecular speciation methods (pncA gene and oxyR pseudogene analysis). Of these samples, 174 isolates simultaneously grew on Löwenstein-Jensen (LJ) and Stonebrink (SB)-containing media and presented phenotypic and molecular profiles of Mycobacterium tuberculosis, whereas 12 had molecular profiles of M. tuberculosis based on the DNA analysis of formalin-fixed paraffin wax-embedded tissue samples (paraffin blocks). One patient produced two sputum isolates, the first of which simultaneously grew on LJ and SB media and presented phenotypic and molecular profiles of M. tuberculosis, and the second of which only grew on SB media and presented phenotypic profiles of Mycobacterium bovis. One patient provided a bronchial lavage isolate, which simultaneously grew on LJ and SB media and presented phenotypic and molecular profiles of M. tuberculosis, but had molecular profiles of M. bovis from paraffin block DNA analysis, and one sample had molecular profiles of M. tuberculosis and M. bovis identified from two distinct paraffin blocks. Moreover, we found a low prevalence (1.6%) of M. bovis among these isolates, which suggests that local health service procedures likely underestimate its real frequency and that it deserves more attention from public health officials.

Changes in population characteristics and their implication on public health research.

Population estimates are generally drawn from one point in time to study disease trends over time; changes in population characteristics over time are usually not assessed and included in the study design. We evaluated whether population characteristics remained static and assessed the degree of population shifts over time. The analysis was based on the New York State 1990 and 2000 census data with adjustments for changes in geographic boundaries. Differences in census tract information were quantified by calculating the mean, median, standard deviation, and the percent of change for each population characteristic. Between 1990 and 2000, positive and negative fluctuations in population size created a U-shaped bimodal pattern of population change which increased the disparities in demographics and socioeconomic status for many census tracts. While 268 (10%) census tracts contracted by 10%, twice as many census tracts (21%, N = 557) grew at least 10%. Notably, the non-Hispanic African-American population grew 10% or more in 152 tracts. Although there were overall reductions in working class and undereducated populations and gains in incomes, most census tracts experienced growing income inequalities and an increased poverty rate. These changes were most pronounced in urban census tracts. Differences in population characteristics in a decade showed growing disparities in demographics and socioeconomic status. This study elucidates that important population shifts should be taken into account when conducting longitudinal research.

2015 South Carolina PV Soft Cost and Workforce Development Part 2: Six Month Confirmation of Anticipated Job Growth

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

Fox, Elise B.; Edwards, Thomas B.

In 2015, a program was initiated to carefully track and monitor the growth of the solar industry in SC. Prior to then, little information was available on the costs associated with distributed photovoltaic (PV) installations in the Southeastern US. For this report, data were collected from businesses on the number of hires they had at the end of 2014 and compared with data for 2015 and June 2016. It was found that the percentage of installers within the state who serve the residential sector increased to 82% from 67%. During the same time period, the average size of initiated installationsmore » for residential, commercial, and utility scale installations all trended upwards. Where residential installations were typically 5 kW-DC in 2014, they were typically 10 kW-DC by late 2015 and in mid-2016. For commercial installations, the average size grew from 84 kW-DC in 2014 to between 136-236 kW-DC in 2015 and then 188-248 kWDC in mid-2016. An exception was seen in utility scale installations where a 2.3 MW-DC system was common in 2014, the size grew to be 5-15 MW-DC in late 2015. The average size dropped 3.1-4.4 MWDC in mid-June 2016, though individual averages up to 20 MW-DC were reported.« less

Diurnal growth rhythms in the chicken eye: relation to myopia development and retinal dopamine levels.

PubMed

Weiss, S; Schaeffel, F

1993-04-01

1. If the eyes of young chickens are deprived of clear vision by translucent occluders, they develop considerable amounts of axial myopia within days. At the same time, the day time retinal dopamine levels drop by about 30%. Because the retinal dopamine levels of normally sighted chicks also differ diurnally and are low at night, we expected that the rate of axial eye growth might also differ during this time. 2. Unexpectedly, eyes grew in length only during the day (about 0.13 mm/day) and even shrank during the night (about -0.04 mm/night, average net growth +0.09 mm in 24 h). 3. If the eyes were occluded, they grew both during the day and also at night (average net growth: +0.16 mm in 24 h). Therefore, development of deprivation myopia was a result of the lack of growth inhibition at night rather than of excessive growth during the day when the actual deprivation occurred. 4. Suppression of dopaminergic retinal pathways by intravitreal injections of the neurotoxin 6-hydroxy-dopamine (6-OHDA) also suppressed development of deprivation myopia and it restored the growth inhibition at night. With normal visual experience, the drug had no effect on axial eye growth and refractive state. 5. Diurnal growth rhythms of the eyes disappeared under continuous light.(ABSTRACT TRUNCATED AT 250 WORDS)

Invasive bacterial infections in a pediatric oncology unit in a tertiary care center.

2014-01-01

Multidrug resistant (MDR) pathogens are becoming a major problem worldwide, more so in the immunocompromised hosts resulting in the urgent need of antibiotic stewardship. To analyze the organisms isolated and the drug resistance pattern in a pediatric oncology unit. Data pertaining to infections with 128 positive cultures in patients with febrile neutropenia over a period of 1-year are presented. The unit antibiotic policy is decided depending on the sensitivity of the prevailing common organisms. We isolated Gram-negative organisms in 56% cases. Escherichia coli and Klebseilla were the most frequent lactose fermenting Gram-negative Bacilli and Pseudomonas and Acinetobacter the nonfermenting Gram-negative Bacilli. Only 20-30% of the Gram-negative organisms cultured were sensitive to a 3rd/4th generation cephalosporin. The combination of a beta-lactam/inhibitor covered 2/3rd of Gram-negative organisms. About 80% of the organisms were sensitive to carbapenems. There was no colistin resistance. About 44% of our cultures grew a Gram-positive bacterial organism and included coagulase negative Staphylococcus. We had an incidence of methicillin resistant Staphylococcus aureus to be 30%. About 30% of the enterococci isolated in our unit were vancomycin-resistant enterococci. About 23% of patients with a positive bacterial culture died. Infections in pediatric cancer patient's account for about 15-20% of the deaths in developing countries as these patients are at a high risk for developing MDR infections. Resistance rates among Gram-positive and Gram-negative organisms have increased worldwide. Every unit needs a rational antibiotic policy. Antibiotic de-escalation and judicious decrease in the duration of antibiotics needs to be practiced.

To review the incidence, culture results, clinical course, management, and visual outcomes of infectious keratitis after photorefractive keratectomy (PRK) at 6 Army and Navy refractive surgery centers. Retrospective study. Twelve thousand six hundred sixty-eight Navy and Army sailors and service members. Army and Navy refractive surgery data banks were searched for cases of infectious keratitis. A retrospective chart review and query of the surgeons involved in the care of those patients thus identified provided data regarding preoperative preparation, perioperative medications, treatment, culture results, clinical course, and final visual acuity. Between January 1995 and May 2004, we performed a total of 25337 PRK procedures at the 6 institutions. Culture proven or clinically suspected infectious keratitis developed in 5 eyes of 5 patients. All patients received topical antibiotics perioperatively. All cases presented 2 to 7 days postoperatively. Cultures from 4 cases grew Staphylococcus, including 2 methicillin-resistant S. aureus (MRSA). One case of presumed infectious keratitis was culture negative. There were no reported cases of mycobacterial or fungal keratitis. In addition, we identified 26 eyes with corneal infiltrates in the first postoperative week that were felt to be sterile, and which resolved upon removal of the bandage contact lens and increasing antibiotic coverage. Infectious keratitis is a rare but potentially vision-threatening complication after PRK. It is often caused by gram-positive organisms, including MRSA. Early diagnosis, appropriate laboratory testing, and aggressive antimicrobial therapy can result in good outcomes.

Viewpoints on the 2017 American Conference on Theoretical Chemistry

From July 17th to 21st, theoretical chemists from the United States and abroad gathered at Boston University to take part in the 2017 American Conference on Theoretical Chemistry (ACTC, http://meetatbu.com/actc). The ACTC grew out of a Gordon Research Conference held biennially from 1962 to 1970. The conference in its current form has been held every three years since 1972. The 2017 conference was chaired by Sharon Hammes-Schiffer (Univ. of Illinois at Urbana-Champaign) and vice-chaired by Todd J. Martiń ez (Stanford Univ). David F. Coker of Boston University served as the Deputy Chair and Local Organizer. More than 30 professors atmore » the forefronts of their respective fields gave talks describing recent research developments. Additionally, over 170 students and postdocs contributed posters detailing their research efforts in theoretical chemistry and its numerous intersecting disciplines. This Viewpoint contains accounts of many of the talks given at the ACTC, delineated by the following concentrations: energy and electron transfer, materials and interfaces, quantum dynamics and spectroscopy, electronic structure, machine learning, and modeling in solution and biological environments. However, most talks could have easily been categorized under two or more of the concentrations listed, emblematic of the large and growing interdisciplinarity in the theoretical chemistry community. The 2017 ACTC was a demonstration of both the depth at which theoretical chemists are understanding fundamental phenomena and the large breadth of topics to which a theoretical chemistry perspective is being applied.« less

Trends in exposure to television food advertisements among children and adolescents in the United States.

To examine the trends in food advertising seen by American children and adolescents. Trend analysis of children's and adolescents' exposure to food advertising in 2003, 2005, and 2007, including separate analyses by race. Children aged 2 to 5 years and 6 to 11 years and adolescents aged 12 to 17 years. Television ratings. Exposure to total food advertising and advertising by food category. Between 2003 and 2007 daily average exposure to food ads fell by 13.7% and 3.7% among young children aged 2 to 5 and 6 to 11 years, respectively, but increased by 3.7% among adolescents aged 12 to 17 years. Exposure to sweets ads fell 41%, 29.3%, and 12.1%, respectively, for 2- to 5-, 6- to 11-, and 12- to 17-year-olds and beverage ads were down by about 27% to 30% across these age groups, with substantial decreases in exposure to ads for the most heavily advertised sugar-sweetened beverages-fruit drinks and regular soft drinks. Exposure to fast food ads increased by 4.7%, 12.2%, and 20.4% among children aged 2 to 5, 6 to 11, and 12 to 17 years, respectively, between 2003 and 2007. The racial gap in exposure to food advertising grew between 2003 and 2007, particularly for fast food ads. A number of positive changes have occurred in children's exposure to food advertising. Continued monitoring of food advertising exposure along with nutritional analyses is needed to further assess self-regulatory pledges.

Spatiotemporal Distribution of Chinavia hilaris (Hemiptera: Pentatomidae) in Corn Farmscapes

2015-01-01

The green stink bug, Chinavia hilaris (Say) (Hemiptera: Pentatomidae), is a pest of cotton in the southeastern United States but little is known concerning its spatiotemporal distribution in corn cropping systems. Therefore, the spatiotemporal distribution of C. hilaris in farmscapes, when corn was adjacent to cotton, peanut, or both, was examined weekly. The spatial patterns of C. hilaris counts were analyzed using Spatial Analysis by Distance Indices methodology. Interpolated maps of C. hilaris density were used to visualize abundance and distribution of C. hilaris in crops in corn–peanut–cotton farmscapes. This stink bug was detected in six of seven corn–cotton farmscapes, four of six corn–peanut farmscapes, and in both corn–peanut–cotton farmscapes. The frequency of C. hilaris in cotton (89.47%) was significantly higher than in peanut (7.02%) or corn (3.51%). This stink bug fed on noncrop hosts that grew in field borders adjacent to crops. The spatial distribution of C. hilaris in crops and the capture of C. hilaris adults and nymphs in pheromone-baited traps near noncrop hosts indicated that these hosts were sources of this stink bug dispersing into crops, primarily cotton. Significant aggregated spatial distributions were detected in cotton on some dates within corn–peanut–cotton farmscapes. Maps of local clustering indices depicted small patches of C. hilaris in cotton or cotton–sorghum at the peanut–cotton interface. Factors affecting the spatiotemporal dynamics of C. hilaris in corn farmscapes are discussed. PMID:25843581
