    2010-01-01

    This case of the work of Ruth Watson Lubic, an internationally known nurse midwife and women's and children's health care activist, provides a modern-day example of the intersection of forceful individual personalities, nursing as a type of activism in itself, and grassroots and local actions that produce larger movement-based activist organizations. Her work as a nurse midwife, in partnership with other nurse midwives, physicians, and community members, illustrates how the efforts of individual actors at a grassroots community level can be as significant as larger traditionally situated activist movements on the lives of everyday citizens.

    2011-01-01

    The Ruth Mine and mill are located in the western Mojave Desert in Inyo County, California (fig. 1). The mill processed gold-silver (Au-Ag) ores mined from the Ruth Au-Ag deposit, which is adjacent to the mill site. The Ruth Au-Ag deposit is hosted in Mesozoic intrusive rocks and is similar to other Au-Ag deposits in the western Mojave Desert that are associated with Miocene volcanic centers that formed on a basement of Mesozoic granitic rocks (Bateman, 1907; Gardner, 1954; Rytuba, 1996). The volcanic rocks consist of silicic domes and associated flows, pyroclastic rocks, and subvolcanic intrusions (fig. 2) that were emplaced into Mesozoic silicic intrusive rocks (Troxel and Morton, 1962). The Ruth Mine is on Federal land managed by the U.S. Bureau of Land Management (BLM). Tailings from the mine have been eroded and transported downstream into Homewood Canyon and then into Searles Valley (figs. 3, 4, 5, and 6). The BLM provided recreational facilities at the mine site for day-use hikers and restored and maintained the original mine buildings in collaboration with local citizen groups for use by visitors (fig. 7). The BLM requested that the U.S. Geological Survey (USGS), in collaboration with Chapman University, measure arsenic (As) and other geochemical constituents in soils and tailings at the mine site and in stream sediments downstream from the mine in Homewood Canyon and in Searles Valley (fig. 3). The request was made because initial sampling of the site by BLM staff indicated high concentrations of As in tailings and soils adjacent to the Ruth Mine. This report summarizes data obtained from field sampling of mine tailings and soils adjacent to the Ruth Mine and stream sediments downstream from the mine on June 7, 2009. Our results permit a preliminary assessment of the sources of As and associated chemical constituents that could potentially impact humans and biota.

    Carbon dioxide (CO(2)), carbon monoxide (CO), and mercury (Hg) emissions were quantified for two eastern Kentucky coal-seam fires, the Truman Shepherd fire in Floyd County and the Ruth Mullins fire in Perry County. This study is one of the first to estimate gas emissions from coal fires using field measurements at gas vents. The Truman Shepherd fire emissions are nearly 1400t CO(2)/yr and 16kg Hg/yr resulting from a coal combustion rate of 450-550t/yr. The sum of CO(2) emissions from seven vents at the Ruth Mullins fire is 726+/-72t/yr, suggesting that the fire is consuming about 250-280t coal/yr. Total Ruth Mullins fire CO and Hg emissions are estimated at 21+/-1.8t/yr and >840+/-170g/yr, respectively. The CO(2) emissions are environmentally significant, but low compared to coal-fired power plants; for example, 3.9x10(6)t CO(2)/yr for a 514-MW boiler in Kentucky. Using simple calculations, CO(2) and Hg emissions from coal-fires in the U.S. are estimated at 1.4x10(7)-2.9x10(8)t/yr and 0.58-11.5t/yr, respectively. This initial work indicates that coal fires may be an important source of CO(2), CO, Hg and other atmospheric constituents. PMID:20071005

  13. Negotiating international bioethics: a response to Tom Beauchamp and Ruth Macklin.

    PubMed

    Baker, Robert

    1998-12-01

    Can the bioethical theories that have served American bioethics so well, serve international bioethics as well? In two papers in the previous issue of the Kennedy Institute of Ethics Journal, I contend that the form of principlist fundamentalism endorsed by American bioethicists like Tom Beauchamp and Ruth Macklin will not play on an international stage. Deploying techniques of postmodern scholarship, I argue that principlist fundamentalism justifies neither the condemnation of the Nazi doctors at Nuremberg, nor, as the Report of the Advisory Committee on the Human Radiation Experiments (ACHRE) demonstrates, condemnation of Cold War radiation researchers. Principlist fundamentalism thus appears to be philosophy bankrupt. In this issue of the Journal, Beauchamp and Macklin reject this claim, arguing that I have misread the ACHRE report and misunderstood Nazism. They also argue that the form of post-postmodern negotiated human rights theory that I proffer is adequate only insofar as it is itself really fundamentalist; insofar as I take postmodernism seriously, however, I mire international bioethics in relativism. In this response, I reaffirm my anti-fundamentalism, provide further evidence in support of my reading of the ACHRE report, and defend my post-postmodern version of rights theory. I also develop criteria for a minimally adequate theoretical framework for international bioethics. PMID:11657321

    Hybridization between species plays an important role in the evolution of secondary metabolites and in the formation of combinations of existing secondary metabolites in plants. We have investigated the content of phenolic compounds in berries and flowers of Vaccinium×intermedium Ruthe, which is a rare natural hybrid between bilberry (Vaccinium myrtillus L.) and lingonberry (Vaccinium vitis-idaea L.). The berries and flowers of the hybrid showed characteristics inherited from both parent species in the distribution and contents of phenolic compounds. Bilberry is known as one of the richest sources of anthocyanins and to have a profile of 15 major forms combining cyanidin, delphinidin, petunidin, peonidin and malvidin with galactose, glucose and arabinose. Lingonberry contains only cyanidin glycosides. Hybrid berries contained all bilberry anthocyanins with pronounced cyanidin content. With regard to proanthocyanidins and flavonol glycosides, the hybrid inherited diverse profiles combining those of both parental species. The distribution of hydroxycinnamic acids was quite uniform in all studied berries. Of the identified compounds, 30 were detected in lingonberry, 46 in bilberry, 53 in hybrid berries and 38 in hybrid flowers. Hence, compared with the parent species, hybrid berries possess a more diverse profile of phenolic compounds and, therefore, can offer interesting material for breeding purposes. PMID:21382629

  17. Effects of Bedrock Lithology and Subglacial Till on the Motion of Ruth Glacier, Alaska, Deduced from Five Pulses from 1973-2012

    A pulse is a type of unstable glacier flow intermediate between normal flow and surging. Using Landsat MSS, TM, and ETM+ imagery and feature tracking software, a time-series of mostly annual velocity maps from 1973 to 2012 was produced that reveals five pulses of Ruth Glacier, Alaska. Peaks in ice velocity were found in the 1981, 1989, 1997, 2003, and 2010; approximately every 7 years. During these peak years the ice velocity increased 300%, from approximately 40 m/yr to 160 m/yr, and occurred in an area of the glacier underlain by sedimentary bedrock. Based on the spatio-temporal behavior of Ruth Glacier during the pulse cycles, we suggest the pulses are due to enhanced basal motion via deformation of a subglacial till. The cyclical nature of the pulses is theorized to be due to a thin till, with low permeability, that causes incomplete drainage of the till between the pulses, followed by eventual recharge and dilation of the till. These findings suggest care is needed when attempting to correlate changes in regional climate with decadal-scale changes in velocity, because in some instances basal conditions may have a greater influence on ice dynamics than climate.

    Phenolic compounds from leaves of lingonberry (Vaccinium vitis-idaea L.), bilberry (Vaccinium myrtillus L.), and the natural hybrid of bilberry and lingonberry (Vaccinium x intermedium Ruthe L., hybrid bilberry) were identified using LC/TOF-MS and LC/MS/MS after extraction from the plant material in methanol in an ultrasonicator. The phenolic profiles in the plants were compared using the LC/TOF-MS responses. This is the first thorough report of phenolic compounds in hybrid bilberry. In total, 51 different phenolic compounds were identified, including flavan-3-ols, proanthocyanidins, flavonols and their glycosides, and various phenolic acid conjugates. Of the identified compounds, 35 were detected in bilberry, 36 in lingonberry, and 46 in the hybrid. To our knowledge, seven compounds were previously unreported in Vaccinium genus and many of the compounds are reported for the first time from bilberry and lingonberry. PMID:19788243

    PubMed

    Boyce, Angie M

    2016-01-01

    This article uses a historical controversy over the U.S. Food and Drug Administration's standard of identity for peanut butter as a site for investigating three topics of high importance for historians of technology, consumption, and food activism: how new industrial food-processing technologies have become regulatory problems; how government, industry, and consumer actors negotiate standards development; and how laypeople try to shape technological artifacts in spaces dominated by experts. It examines the trajectory of consumer activist Ruth Desmond, co-founder of the organization the Federation of Homemakers. By following Desmond's evolving strategies, the article shows how the broader currents of the 1960s-70s consumer movement played out in a particular case. Initially Desmond used a traditional style that heavily emphasized her gendered identity, working within a grassroots organization to promote legislative and regulatory reforms. Later, she moved to a more modern advocacy approach, using adversarial legal methods to fight for consumer protections. PMID:26971728

    In the most significant constitutional decision of the last generation, Carter v. Canada, the Supreme Court of Canada reversed itself and decided that it was possible for Parliament to enact safeguards that would be adequate to protect persons who are vulnerable in times of weakness, then proceeded to declare that Canadians were entitled to a s. 7 Charter right to physician-assisted death. David Baker and Gilbert Sharpe accepted the challenge issued by the Court and drafted a Bill to amend the Criminal Code in a manner they believed would strike a constitutional balance between providing access to the right declared by the Court and protecting the vulnerable. This article represents their attempt, along with co-author Rebeka Lauks, to explain many of the key provisions in their draft. Amongst the most noteworthy are their attempts to ensure that those choosing PAD are informed about quality of life, as well as treatment choices; to define vulnerability and to install safeguards adequate to protect persons while vulnerable; and finally a prior review process that would ensure both ready access to the Charter right declared by the Court and consistent and transparent application of the law. The authors have attempted to establish an alternative model to that currently in effect in the Benelux countries, which they regard as having been ineffective in achieving any of these objectives.

  3. Polymerisation of composite materials in space environment for development of moon base

    NASA Astrophysics Data System (ADS)

    Kondyurina, I.; Kondyurin, A.; Lauke, B.

    The best way for a Moon base creation is a deployment of light construction on Moon surface after landing. The construction has to be light in deployment and hard at exploitation. A number of proposals for solidification of deployed constructions in space were presented, but the best way is a chemical reaction which leads to a formation of hard frame of space construction. A technology of large-size moon module for industrial and scientific applications is developed on the base of polymerisation technique of composite material with liquid polymer matrix. Experiments with chemical reactions of polymerisation in composite materials under high vacuum, ion beam and plasma discharge showed a possibility to use a liquid viscous polymer matrix of composite materials under space conditions without hermetic coating. Epoxy resins with thermal and photo initiation system of polymerisation were studied. The effects of initiation of the polymerisation reaction under simulated space factors were observed. The polymerised frames can be used in energetic, electronic and other industries on Moon surface. The investigations were partially supported by Alexander von Humboldt Foundation and European Space Agency, ESTEC (contract 17083/03/NL/Sfe "Space Environmental Effects on the Polymerisation of Composite Structures"). 1.

    It is well-known that the carrier mobility of an organic field effect semiconductor (FET) depended on the crystal quality and/or the crystal perfection of the organic thin films [T.W. Kelly, D.V. Muyres, P.F. Baude, T.P. Smith, T.D. Jones, Mater. Res. Soc. Symp. Proc. 771 (2003) L6.5.1; D.J. Gundlach, J.A. Nichols, L. Zhou, T.N. Jackson, Appl. Phys. Lett. 80 (2002) 2925; H.K. Lauk, M.

A 201 (2004) 1031]. To improve the crystal quality of the thin film many efforts were made. One of the important improvements was the surface treatment of the substrate. The tetracene thin film FET (top contact structure) was fabricated using the substrate, which was coated by a spin-coating method with a 0.1% poly α-methylstyrene (AMS) solution. The crystal quality was improved by this treatment so that the carrier mobility was higher than that of non-treatment. The maximum mobility of the AMS-treated sample was obtained to be 0.12 cm 2/V s.

  5. Polymerisation processes in expoy resins under influence of free space environment

    NASA Astrophysics Data System (ADS)

    Kondyurin, A.; Lauke, B.; Kondyurina, I.

    A creation of large size constructions in space or on celestial bodies is possible by the way of chemical reactions of liquid viscous components under space environment conditions [1-2]. In particular, a new technology for large-size space module for electronic components, energy and materials production is developed on the basis of polymerisation technique. The factors of free space environment have a significant influence on the polymerisation processes. The polymerisation processes in active liquid components are sensitive to microgravitation, temperature variations (-150{ldots}+1500C), high vacuum (10-3{ldots}10-7 Pa), atomic oxygen flux (on LEO), UV and VUV irradiations, X-ray and γ -irradiations, high energy electron and ion fluxes. Experiments of polymerisation processes under simulated free space conditions were conducted. The influences of high vacuum, high energy ion beam and rf- and mw-plasma on polymerisation of epoxy resins were observed. The effects of low molecular components evaporations, free radical formations, additional chemical reactions and mixing processes during polymerisation were observed. Our results showed, that the space factors can initiate the polymerisation reaction in epoxy matrix of glass and carbon fibre composites. The result can be used for a technology for large size constructions on Earth orbit, in far space and on space bodies as for deployed antennas, solar sail stringers, solar shield stringers, frame for large-size space station, frame for Moon, Mars, asteroids bases, frame for space plant on Earth orbit and on other celestial bodies.

  11. Electrospray deposition of chalcogenide glass films for gradient refractive index and quantum dot incorporation

    NASA Astrophysics Data System (ADS)

    Novak, Spencer

    Chalcogenide glasses (ChGs) are well-known for their optical properties, making them ideal candidates for emerging applications of mid-infrared microphotonic devices, such as lab-on-a-chip chemical sensing devices, which currently demand additional flexibility in processing and materials available to realize new device designs. Solution-derived processing of ChG films, initially developed in the 1980s by Chern and Lauks, has consisted mainly of spin-coating and offers unique advantages over the more traditional physical vapor deposition techniques. In the present effort, the nanoparticles of interest are luminescent quantum dots (QDs), which can be used as an on-chip source of light for a planar chemical sensing device. Prior efforts of QD incorporation have exposed limitations of spin-coating of ChG solutions, namely QD aggregation and material waste, along with incompatibility with larger scale manufacturing methods such roll-to-roll processing. This dissertation has evaluated electrospray (ES) as an alternative method of solution-derived chalcogenide glass film deposition. While employed in other materials systems, deposition of optical quality ChG films via electrospray has not been previously attempted, nor have parameters until now, been defined. This study has defined pre-cursor solution chemistry, electrospray jet process parameters required for formation of stable films, annealing protocols and resulting film attributes, yielding important correlations needed to realize high optical quality films. Electrosprayed films attributes were compared to those seen for spin coating and trade-offs in processing route and resulting quality, were identified. Optical properties of importance to device applications were defined, including surface roughness, refractive index, and infrared transmission. The use of a serpentine path of the spray over the substrate was demonstrated to obtain uniform thickness, blanket films, and demonstrates process compatibility with roll

He tells a number of stories about his family, which moved from Alto Juruá to Manaus to escape malaria and other fevers. He says it is essential to adopt homeopathy, acupuncture, and other indigenous knowledge and practices in treating disease. Barros also talks about measures taken when he was president of Brazil's national environmental institute, Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (Ibama)--all part of an effort to prevent and combat these diseases and halt deforestation and burn-offs.

    Critics' of big-time college sports have been working for decades to control the rampant rise in commercialization on campus--and to hold the line on academic integrity. But the balancing act is a difficult one--as 2003, a year that saw academic scandals at St. Bonaventure University, University of Georgia, and Fresno State University, to name…

  14. Volatiles from intact and Lygus-damaged Erigeron annuus (L.) Pers. are highly attractive to ovipositing Lygus and its parasitoid Peristenus relictus Ruthe.

    Trap cropping and biological control can provide a sustainable means of controlling insect pests. Insects in the genus Lygus (Hemiptera: Miridae) are major pests on cotton and horticultural crops throughout the United States, and pesticide resistance within Lygus populations necessitates more sustainable long-term management techniques. Here, we explore behavioral responses of Lygus bugs (L. rubrosignatus Knight) and an introduced parasitoid, Peristenus relictus (Hymenoptera: Braconidae), to a common field edge plant, Erigeron annuus, which has the potential to serve as a trap host. Erigeron annuus is attractive to Lygus in the field, with Lygus preferentially moving to Erigeron patches compared to more abundant cotton plants. To determine the role of odor cues in mediating this attraction, we collected volatiles from E. annuus with and without Lygus damage, and then tested the attractiveness of these volatiles vs. those of cotton to Lygus females and female P. relictus wasps using Y-tube and wind tunnel bioassays. We found that undamaged E. annuus emits high concentrations of a complex volatile blend (60+ compounds), with novel compounds induced and constitutive compounds up-regulated in response to damage. Additionally, both female Lygus bugs and female P. relictus wasps are highly attracted to E. annuus volatiles over those of cotton in almost every combination of damage treatments. Our results suggest that Erigeron annuus would be an effective trap plant to control Lygus in cotton, since it is highly attractive to both the pest and its natural enemy. PMID:23982679

    England, Philip C.; Walker, Richard T.

    2016-01-01

    Shi et al. (2015) analysed the distributions of elevation of palaeoshorelines around Siling Tso, central Tibet assuming a model in which surface loads are entirely supported by an elastic lid overlying an inviscid fluid. They concluded that the thickness of the elastic lid is 20-30 km and that, for the assumption of an inviscid substrate in this model to be valid, the viscosity of the crust below the elastic lid must be less than 1- 2 ×1019 Pas. Here we relax the assumption of an inviscid lower crust and show that the distribution of shoreline elevations may be explained either by a thick elastic lid or by high viscosity in the lower crust. In the limit of an inviscid lower crust, the thickness of the elastic lid must be greater than 25 to 39 km. If the elastic lid is thinner than this, then the viscosity of the crust beneath must be at least 5 ×1019 to 2 ×1020 Pas, depending on the time interval over which the lake was loaded.

  2. Origins of the WHO Framework Convention on Tobacco Control

    PubMed Central

    Roemer, Ruth; Taylor, Allyn; Lariviere, Jean

    2005-01-01

    The World Health Organization (WHO) Framework Convention on Tobacco Control originated in 1993 with a decision by Ruth Roemer and Allyn Taylor to apply to tobacco control Taylor’s idea that the WHO should utilize its constitutional authority to develop international conventions to advance global health. In 1995, Taylor and Ruth Roemer proposed various options to WHO, recommending the framework convention-protocol approach conceptualized by Taylor. Despite initial resistance by some WHO officials, this approach gained wide acceptance. In 1996, the World Health Assembly voted to proceed with its development. Negotiations by WHO member states led the World Health Assembly in May 2003 to adopt by consensus the WHO Framework Convention on Tobacco Control—the first international treaty adopted under WHO auspices. The treaty formally entered into force for state parties on February 27, 2005. PMID:15914812

  3. Geological and geochemical studies in the Robinson Mining District, White Pine County, Nevada, using Skylab S190A imagery

    NASA Technical Reports Server (NTRS)

    Jensen, M. L. (Principal Investigator); Rogers, R. J.; Erickson, M. P.

    1973-01-01

    The author has identified the following significant results. In the Robinson mining district which included the Ruth porphyry copper mines, three large positive aeromagnetic anomalies exist over a Tertiary volcanic area north west of Ruth. Prior studies of this area have suggested that the volcanics may or may not be the cause of the anomalies. Skylab Sl90A imagery, however, indicates possible outcrops in the volcanic area of the Paleozoic sediments. Field studies or ground truth verify the existence of these inliers suggesting that the magnetic anomaly may be the result of a buried intrusive body for which potential mineralization has been covered by the post-ore blanket of volcanics. The area is being mapped in more detail and samples of mercury-bearing soil-gas area being collected within and outside the area.

    The history of sports is closely tied to the larger history of the society in which they are played. Baseball in the United States in the 1920's and l930's assumed a major role in spreading the ideals of fair play, sportsmanship, and democracy to the Far East, with tours by amateur athletes and professionals such as Lou Gehrig and Babe Ruth.

    Your article about the two female physicists in Israel (pictured above) who are identical twins raised the question of whether any other such twins exist (January p3). My identical twin sister and I were both undergraduates at Imperial College, being in the first cohort of students to graduate in materials science in 1973.

    In normal growth conditions, total protein percent (salt soluble plus hordein fractions) in the endosperm at maturity in barley cultivar Hordeum vulgare L. cv `Ruth' was about 14%, whereas in an accession of wild barley, Hordeum spontaneum Koch line 297, it was about 28%. Spike culture experiments were conducted to ascertain whether there were basic differences between the two genotypes under conditions of widely different nitrogen supply. Spikes of each genotype were grown from 8 to 25 days after flowering in in vitro culture in a growth medium containing 0 to 4 grams per liter nitrogen supplied as NH4NO3. Spikes were pulse-labeled at intervals from 12 to 24 days after flowering with 3.7 megabecquerel of [3H]leucine to determine relative rates of synthesis of hordein-1 and hordein-2 polypeptides. At low nitrogen levels `Ruth' had a lower protein content than 297, but at increasing nitrogen levels its protein content increased rapidly and reached a maximum (35%) higher than 297 (30%). The relative contribution of the hordein fraction to total protein increased mainly with time, and hordein-1 to total hordein increased mainly with nitrogen level, in both genotypes. There appeared to be no fundamental limitations in the capacity of `Ruth' to accumulate protein; 297 appears to have a greater basal level of nitrogen availability under normal conditions.

    Responding to Ruth McDonald's editorial on the rise of leadership and leadership development programmes in healthcare, this paper offers three arguments. Firstly, care is needed in evaluating impact of leadership development, since achievement of organisational goals is not necessarily an appropriate measure of good leadership. Secondly, the proliferation of styles of leadership might be understood in part as a means of retaining control over public services while distributing responsibility for their success and failure. Thirdly, it makes a plea for the continued utility of good administrative skills for clinicians and managers, which are likely to become all-the-more important given recent developments in healthcare policy and governance.

  16. Psychology and "the Babe".

    PubMed

    Fuchs, A H

    1998-01-01

    Psychologists and baseball players were among those Americans who formed professional associations in the last quarter of the nineteenth century. Psychologists used laboratory tasks to quantify mental and behavioral processes while sportswriters and baseball organizers measured individual and team performance. The most popular baseball player of the 1920s, George Herman "Babe" Ruth, possessed superior batting skills that were evident in the statistical indices of baseball performance. In 1921, he was brought to the psychological laboratory at Columbia University to perform standard laboratory tasks in an effort to discover the basis for his success in hitting home runs and to suggest the potential of tests for identifying future baseball stars. Baseball's addiction to quantitative indices of performance was thus brought together with a new science devoted to quantitative assessment and a desire to make such assessments useful. The attempt to analyze the basis of Ruth's batting skills is part of the history of applied psychology, sport psychology, and popular interest in the science of psychology. PMID:9580977

    The author has identified the following significant results. A significant and possible major economic example of the practical value of Skylab photographs was provided by locating on Skylab Camera Station Number 4, frame 010, SL-2, an area of exposures of limestone rocks which were thought to be completely covered by volcanic rocks based upon prior mapping. The area is located less than 12 miles north of the Ruth porphyry copper deposit, White Pine County, Nevada. This is a major copper producing open pit mine owned by Kennecott Copper Corporation. Geophysical maps consisting of gravity and aeromagnetic studies have been published indicating three large positive magnetic anomalies located at the Ruth ore deposits, the Ward Mountain, not a mineralized area, and in the area previously thought to be completely covered by post-ore volcanics. Skylab photos indicate, however, that erosion has removed volcanic cover in specific sites sufficient to expose the underlying older rocks suggesting, therefore, that the volcanic rocks may not be the cause of the aeromagnetic anomaly. Field studies have verified the initial interpretations made from the Skylab photos. The potential significance of this study is that the large positive aeromagnetic anomaly suggests the presence of cooled and solidified magma below the anomalies, in which ore-bearing solutions may have been derived forming possible large ore deposits.

    The interplay of policy, milestone events, and cornerstone documents was critical in the evolution of the specialty of public health nursing (PHN) from 1890-1950. Using our contemporary lens, this article examines PHN development from an historical perspective, including events and milestones driving growth in the early 20th century. Some of the challenges faced by our founding public health nursing leadership are not unlike challenges we face today. In 1950, Ruth Hubbard, a former leader in the National Organization of Public Health Nurses and Director of the Visiting Nurse Society of Philadelphia, spoke of the value of examining the past to forge a new future. This article calls for contemporary public health nurses to act upon the lessons learned from the past, to strengthen the renewed focus on prevention, to develop policies that impact population health, and to foster a vision that will guide us into the future.

    The suitability of the Simple Biosphere (SiB) model of Sellers et al. (1986) for calculation of the surface fluxes for use within general circulation models is assessed. The structure of the SiB model is described, and its performance is evaluated in terms of its ability to realistically and accurately simulate biophysical processes over a number of test sites, including Ruthe (Germany), South Carolina (U.S.), and Central Wales (UK), for which point biophysical and micrometeorological data were available. The model produced simulations of the energy balances of barley, wheat, maize, and Norway Spruce sites over periods ranging from 1 to 40 days. Generally, it was found that the model reproduced time series of latent, sensible, and ground-heat fluxes and surface radiative temperature comparable with the available data.

    The GEO 600 gravitational wave detector is at an advanced stage of construction at Ruthe, near Hannover in Northern Germany. Successful long-term stable operation of long-baseline interferometers like GEO 600 will critically depend on continuous monitoring and control of the very large number of interdependent feedback systems involved. We present here a description of the control infrastructure developed for this task for GEO 600. Our solution is based on a combination of purpose-built interfacing hardware, standard local area network-connected personal computers, and control software written using LabVIEW. The software techniques developed allow monitoring of all detector systems and also provide the mechanisms for manual and automated control both locally and from remote internet-connected sites.

    The GEO 600 gravitational wave detector (1) is currently under construction at Ruthe, near Hannover in Germany. The design of the suspension system for the main mirrors in the detector has been chosen such that thermal noise due to the internal modes of the mirrors is expected to set the sensitivity limit from 50 Hz to ~200 Hz. Thus the design must be such that the effects of seismic noise and thermal noise from the suspensions are lower than the ``internal'' thermal noise at and above 50 Hz. To achieve this, a triple pendulum suspension incorporating fused silica fibers in the lowest stage forms the major part of the overall suspension and isolation system. In this paper, recent work on developing several aspects of the triple pendulum design is discussed. .

    PubMed

    Omelyan, I P

    2006-09-01

    A class of symplectic algorithms is introduced to integrate the equations of motion in many-body systems. The algorithms are derived on the basis of an advanced gradientlike decomposition approach. Its main advantage over the standard gradient scheme is the avoidance of time-consuming evaluations of force gradients by force extrapolation without any loss of precision. As a result, the efficiency of the integration improves significantly. The algorithms obtained are analyzed and optimized using an error-function theory. The best among them are tested in actual molecular dynamics and celestial mechanics simulations for comparison with well-known nongradient and gradient algorithms such as the Störmer-Verlet, Runge-Kutta, Cowell-Numerov, Forest-Ruth, Suzuki-Chin, and others. It is demonstrated that for moderate and high accuracy, the extrapolated algorithms should be considered as the most efficient for the integration of motion in molecular dynamics simulations.

    Three Seasat synthetic aperture radar (SAR) and three Landsat multispectral scanner subsystem (MSS) scenes of three areas of Alaska were analyzed for hydrological information. The areas were: the Dease Inlet in northern Alaska and its oriented or thaw lakes, the Ruth and Tokositna valley glaciers in south central Alaska, and the Malaspina piedmont glacier on Alaska's southern coast. Results for the first area showed that the location and identification of some older remnant lake basins were more easily determined in the registered data using an MSS/SAR overlay than in either SAR or MSS data alone. Separately, both SAR and MSS data were useful for determination of surging glaciers based on their distinctive medial moraines, and Landsat data were useful for locating the glacier firn zone. For the Malaspina Glacier scenes, the SAR data were useful for locating heavily crevassed ice beneath glacial debris, and Landsat provided data concerning the extent of the debris overlying the glacier.

    Engle, Mark A.; Olea, Ricardo A.; O'Keefe, Jennifer M. K.; Hower, James C.; Geboy, Nicholas J.

    2013-01-01

    Coal fires occur in nature spontaneously, contribute to increases in greenhouse gases, and emit atmospheric toxicants. Increasing interest in quantifying coal fire emissions has resulted in the adaptation and development of specialized approaches and adoption of numerical modeling techniques. Overview of these methods for direct estimation of diffuse gas emissions from coal fires is presented in this paper. Here we take advantage of stochastic Gaussian simulation to interpolate CO2 fluxes measured using a dynamic closed chamber at the Ruth Mullins coal fire in Perry County, Kentucky. This approach allows for preparing a map of diffuse gas emissions, one of the two primary ways that gases emanate from coal fires, and establishing the reliability of the study both locally and for the entire fire. Future research directions include continuous and automated sampling to improve quantification of gaseous coal fire emissions.

  13. The verbal portrait: Erik H. Erikson's contribution to psychoanalytic discourse.

    PubMed

    Capps, Donald

    2011-12-01

    This article makes the case that Erik H. Erikson developed a form of psychoanalytic discourse-the verbal portrait-which, although not unprecedented, became a focal feature of his work, and the testing ground for the cogency of his major contribution to psychoanalysis (the concept of identity). It suggests that Erikson was inspired to develop the verbal portrait because he came to psychoanalysis from art and was, in fact, a portrait artist. Drawing especially on the work of Richard Brilliant, it presents the view that a portrait is a portrayal of the subject's identity and goes on to show how Erikson's memorial to the cultural anthropologist Ruth Benedict is representative of the verbal portrait.

    D. P. Phillips, T. E. Ruth, and L. M. Wagner (1993) reported that 1969-1990 California mortality data show that Chinese Americans are particularly vulnerable to diseases that Chinese astrology and traditional Chinese medicine associate with their birth years. For example, because fire is associated with the heart, a Chinese person born in a fire year (such as 1937) is more likely to die of heart disease than is a Chinese person born in a nonfire year. However, many diseases were excluded from this study, some diseases that were included have ambiguous links to birth years, and the statistical tests were indirect. A more complete statistical analysis and independent California mortality data for the years 1960-1968 and 1991-2002 did not replicate the original results. PMID:16448306

    1997-03-01

    Democratic government requires trust: people need to know and believe that the government is telling the truth. Without information about what the government is doing and why, citizens cannot exercise democratic control over government institutions. During his first year in office, President Clinton became concerned about reports that the government had conducted unethical secret human radiation experiments during the Cold War. To address this issue, in January 1994, President Clinton established the Advisory Committee on Human Radiation Experiments (ACHRE), chaired by bioethicist Dr. Ruth Faden of Johns Hopkins University. The President also directed all Federal agencies to search for records related to human subjects radiation research and provide them to the Advisory Committee. This report presents the Administration`s actions to respond to the ACHRE`s findings and recommendations.

    In the book Their Day in the Sun, Ruth Howes and Caroline Herzenberg documented more than 1000 women who worked on the Manhattan Project, preserving their legacy for generations to come. At the 2009 Chicago meeting, the AAPT Committee on Women in Physics celebrated the accomplishments of these women and the men who worked beside them. Howes presented an overview of the contributions of women to the development of the first nuclear weapon, and the session was honored with talks from two Manhattan project veterans, Ellen Cleminshaw Weaver, who worked at Oak Ridge, and Dorothy Marcus Gans, who worked as a technician in the Metallurgical Laboratory in Chicago. I will present a summary of the session, analyzing the effect of working on the project on the career trajectories of the women involved, and point listeners toward additional documentation of this history.

    Nanowhiskers are defect free single crystals with high aspect ratios and as result exhibit superior physical, e.g. mechanical properties. This paper sheds light on the kinetics of copper nanowhisker growth and thickening. Whisker growth was provoked by covering silicon wafers with a thin carbon film and subsequently coating them with copper by molecular beam epitaxy. The whiskers grown were examined by scanning electron microscopy and the length and diameter were measured as a function of the amount of copper deposited. The experiments show that nanowhisker growth follows Ruth and Hirth's growth model. A fit of the model parameters to the acquired data shows that adsorption of atoms on the substrate and on the whisker surface, with subsequent surface diffusion to the whisker tip, delivers by far the greatest portion of material for whisker growth. Additionally, the experiments demonstrate that the crystallographic orientation of the substrate surface greatly influences the growth rate in the early stage of whisker growth.

    For the measurement of water quality in freshwater systems, there are established indices using macroinvertebrate larvae. There is no such comparable measure for marine and estuarine environments. A phytoplankton diversity index (PDI), whose basic form was conceived by Dr. Ruth Gyure of Save the Sound, Inc., is being investigated as a possible candidate to rectify this situation. Phytoplankton were chosen as the indicators of water quality since algae have short generation times and respond quickly to changing water quality conditions. The methodologies involved in this initial assessment of the PDI are incorporated into the Adopt-a-Harbor water quality monitoring program and its associated laboratory. The virtues of the procedures are that they are simple and quick to use, suitable for trained volunteers to carry out, easily reproducible, and amenable to quality assurance checks.

    This paper discuss a food chain model on a microbiology ecosystem in the ocean, where predation process occurs. Four population growth rates are discussed, namely bacteria, phytoplankton, zooplankton, and protozoa growth rate. When the growth of nutrient density is also considered, the model is governed by a five dimensional dynamical system. The system considered in this paper is a modification of a model proposed by Hadley and Forbes [1], by taking Holling Type I as the functional response. For sake of simplicity, the model needs to be scaled. Dynamical behavior, such as existence condition of equilibrium points and their local stability are addressed. There are eight equilibrium points, where two of them exist under certain conditions. Three equilibrium points are unstable, while two points stable under certain conditions and the other three points are stable if the Ruth-Hurwitz criteria are satisfied. Numerical simulations are carried out to illustrate analytical findings.

  7. Self-Evaporation Phenornenon of Water Accornpanied by a Circulation Flow in a Vessel

    NASA Astrophysics Data System (ADS)

    Ogoshi, Hidemasa; Aizawa, Kazuo

    Characteristics of the self-evaporation of hot water in a vertical vessel with internal baffles were investigated experimentally by using a visual hot model. The experiment apparatus was designed by modeling Ruths' varying pressure steam accumulator, and consisted of a vertical straight vessel (100mm in diameter and 1500mm in height) and internal baffles such as a straight pipe (60mm in diameter) and tapered tubes which were installed concentric to the vessel. Self-evaporation experiments were executed under vacuum pressure conditions. It was found that a permanent circulation of hot water was naturally induced in the vessel macroscopically, and nucleation took place within the upper part of the internal baffles near the water surface along this water circulation. Self-evaporation could go on steadily and the temperature uniformity in hot water layer could be improved remarkably in comparison with the case with no internal baffles. In this case, large portion of the self-evaporation of hot water resulted from the hydraulic pressure loss during the upward flow motion in the inner pipe.

  8. Systematics-insensitive Periodic Signal Search with K2

    From pulsating stars to transiting exoplanets, the search for periodic signals in K2 data, Kepler’s two-wheeled extension, is relevant to a long list of scientific goals. Systematics affecting K2 light curves due to the decreased spacecraft pointing precision inhibit the easy extraction of periodic signals from the data. We here develop a method for producing periodograms of K2 light curves that are insensitive to pointing-induced systematics; the Systematics-insensitive Periodogram (SIP). Traditional sine-fitting periodograms use a generative model to find the frequency of a sinusoid that best describes the data. We extend this principle by including systematic trends, based on a set of “eigen light curves,” following Foreman-Mackey et al., in our generative model as well as a sum of sine and cosine functions over a grid of frequencies. Using this method we are able to produce periodograms with vastly reduced systematic features. The quality of the resulting periodograms are such that we can recover acoustic oscillations in giant stars and measure stellar rotation periods without the need for any detrending. The algorithm is also applicable to the detection of other periodic phenomena such as variable stars, eclipsing binaries and short-period exoplanet candidates. The SIP code is available at https://github.com/RuthAngus/SIPK2.

    Nursing research and nurse researchers have been an integral and significant part of the Oncology Nursing Society's (ONS's) history, as evidenced by the development of the Nursing Research Committee within a few years of ONS's establishment. Ruth McCorkle, PhD, RN, FAAN, was the committee's first chairperson in 1979. This was followed by the creation of the Advanced Nursing Research Special Interest Group in 1989 under the leadership of Jean Brown, PhD, RN, FAAN. ONS also began to recognize nurse researchers in 1994 by creating the annual ONS Distinguished Researcher Award to recognize the contributions of a member who has conducted or promoted research that has enhanced the science and practice of oncology nursing. The list of recipients and of their work is impressive and reflects the wide range of our practice areas (see http://bit.ly/1MTC5cp for the recipient list). In addition, the ONS Foundation began funding research in 1981 and has distributed more than $24 million in research grants, research fellowships, and other scholarships, lectures, public education projects, and career development awards (ONS Foundation, 2015). And, in 2006, the Putting Evidence Into Practice resource was unveiled, which provides evidence-based intervention reviews for the 20 most common problems experienced by patients with cancer and their caregivers (www.ons

  10. Dignity: not such a useless concept.

    PubMed

    Killmister, Suzy

    2010-03-01

    In her 2003 article in the British Medical Journal, Ruth Macklin provocatively declared dignity to be a useless concept: either a vague restatement of other more precise values, such as autonomy or respect for persons, or an empty slogan. A recent response to Macklin has challenged this claim. Doris Schroeder attempts to rescue dignity by positing four distinct concepts that fall under the one umbrella term. She argues that much of the confusion surrounding dignity is due to the lack of disambiguation among these four concepts, but that once we understand the different values in question dignity becomes a powerful tool in the fields of human rights and bioethics. It is the goal of this paper to build upon Schroeder's insights by reconnecting the multiple strands of dignity she identifies. It will be argued that the usefulness of dignity as a guiding principle in medical ethics can be much improved by identifying the single conceptual link that ties together the various values flying under its banner. That conceptual link is provided by understanding dignity as the capacity to live by one's standards and principles. PMID:20211996

  11. What is so important about completing lives? A critique of the modified youngest first principle of scarce resource allocation.

    PubMed

    Gamlund, Espen

    2016-04-01

    Ruth Tallman has recently offered a defense of the modified youngest first principle of scarce resource allocation [1]. According to Tallman, this principle calls for prioritizing adolescents and young adults between 15-40 years of age. In this article, I argue that Tallman's defense of the modified youngest first principle is vulnerable to important objections, and that it is thus unsuitable as a basis for allocating resources. Moreover, Tallman makes claims about the badness of death for individuals at different ages, but she lacks an account of the loss involved in dying to support her claims. To fill this gap in Tallman's account, I propose a view on the badness of death that I call 'Deprivationism'. I argue that this view explains why death is bad for those who die, and that it has some advantages over Tallman's complete lives view in the context of scarce resource allocation. Finally, I consider some objections to the relevance of Deprivationism to resource allocation, and offer my responses. PMID:27059376

  12. Reporting AIDS in Kenya: a personal report. Guidelines for journalists have been issued in the UK. What about Africa?

    Hanssen, N

    1993-01-01

    A Norwegian journalist reports on his experiences covering the acquired immunodeficiency syndrome (AIDS) epidemic in Kenya. Denial by the government has resulted in reduced figures. President Daniel Arap Moi refuses to admit that the epidemic has become national in scope. The public broadcasting services carry little information about the epidemic. A study indicating that 25/1700 prostitutes in Nairobi were positive for human immunodeficiency virus (HIV) has been met with skepticism by the public, who question the survey (what was the relationship between researchers and prostitutes, were the prostitutes paid to risk their lives, why was the study carried out in Africa). Some believe the 25 positive women are 'immune' because of a similar gene pattern. There are 750,000 HIV positive adults and 30,000 AIDS cases in Kenya, including a large number of cases among street urchins. Most AIDS cases are sent home to die because of the short supply of hospital beds (45,000). One of these was Ruth Kasuki, a 36-year-old mother of three and AIDS educator and counselor in Kenya, who is now deceased. In an interview conducted shortly before her death, she criticizes the government for its denial and predicts disastrous results. Ms. Kasuki also blamed the extramarital affairs of men for the spread of AIDS among Kenyan women. 8% of women receiving antenatal care are estimated to have HIV; in Nyanza Coast and Nairobi the estimate reaches 12%. Ms. Kasuki also cited the negative attitude of the clergy. PMID:12287718

  13. Studying populations without molecular biology: Aster Models and a new argument against reductionism.

    PubMed

    Grosholz, Emily

    2011-06-01

    During the past few decades, philosophers of biology have debated the issue of reductionism versus anti-reductionism, with both sides often claiming a 'pluralist' position. However, both sides also tend to focus on a single research paradigm, which analyzes living things in terms of certain macromolecular components. I offer a case study where biologists pursue other analytic pathways, in a tradition of quantitative genetics that originates with the initially purely mathematical theories of R. A. Fisher, J. B. S. Haldane, and Sewall Wright in the 1930s. Aster Models (developed by Ruth Shaw and Charles Geyer) offers a class of statistical models designed for studying the fitness of plant and animal populations, by integrating the measurements of separate, sequential, non-normally distributed fitness components in novel ways. Their work generates important theoretical and practical results that do not require elaboration by molecular biology, and thus serves as a counterexample to the claims of philosophers whose 'pluralism' still harbors reductionist assumptions.

    Hiromi Kubagawa and John E. Coligan coordinated an online meeting to define an appropriate nomenclature for the cell surface glycoprotein presently designated by different names: Toso, Fas apoptosis inhibitory molecule 3 (FAIM3), and IgM FcR (FcμR). FAIM3 and Faim3 are the currently approved symbols for the human and mouse genes, respectively, in the National Center for Biotechnology Information, Ensembl, and other databases. However, recent functional results reported by several groups of investigators strongly support a recommendation for renaming FAIM3/Faim3 as FCMR/Fcmr, a name better reflecting its physiological function as the FcR for IgM. Participants included 12 investigators involved in studying Toso/FAIM3(Faim3)/FμR, representatives from the Human Genome Nomenclature Committee (Ruth Seal) and the Mouse Genome Nomenclature Committee (Monica McAndrews), and an observer from the IgM research field (Michael Carroll). In this article, we provide a brief background of the key research on the Toso/FAIM3(Faim3)/FcμR proteins, focusing on the ligand specificity and functional activity, followed by a brief summary of discussion about adopting a single name for this molecule and its gene and a resulting recommendation for genome nomenclature committees.

    Lygus Hahn plant bugs (Hemiptera: Miridae) are serious pests of a wide variety of economically important crops in North America. European Peristenus digoneutis Loan and P. relictus Ruthe (Hymenoptera: Braconidae) are being considered for release in Canada as part of a classical biological control program for Lygus. The attractiveness of different host plants to European Peristenus has not been addressed, but may be an important consideration prior to parasitoid release. Lygus rugulipennis Poppius nymphs were collected in the Northern Temperate Atlantic (NTA) ecoregion on red clover (Trifolium pratense L.; Fabaceae) and chamomile (Matricaria recutita L.; Asteraceae), and in the Western European Broadleaf Forest (WEBF) ecoregion on red clover and alfalfa (Medicago sativa L.; Fabaceae). Parasitism levels and parasitoid species were determined using a multiplex PCR assay for P. digoneutis, P. relictus, and P. pallipes Curtis. Mean parasitism levels in L. rugulipennis were 45-49% in the NTA ecoregion and 25-32% in the WEBF ecoregion. However, in neither ecoregion were parasitism levels and parasitoid species compositions significantly different in nymphs from different host plant species. Furthermore, multiparasitism was low despite the fact that P. digoneutis and P. relictus share the same host species. PMID:18439339

    In the early 1990s Ruth Howes, a nuclear physicist on the faculty at Ball State University, and Caroline Herzenberg, a nuclear physicist at Argonne National Laboratory, were asked to write a chapter on the Manhattan Project for a volume on women working on weapons development for the military. Realizing that they knew very little about the women who had been involved in that effort, they embarked on a mission to find out more. Howes and Herzenberg were able to document the wartime contributions of more than 1000 women in Their Day in the Sun,2 preserving this legacy for generations to come. At the 2009 AAPT Winter Meeting in Chicago, the AAPT Committee on Women in Physics celebrated the accomplishments of these women and the men who worked beside them in a session co-sponsored with the History and Philosophy of Physics and the Concerns of Senior Physicists committees. Howes presented an overview of the contributions of women to the development of the first nuclear weapon, and the session was honored with the presence of Manhattan Project veterans Ellen Cleminshaw Weaver, who worked at Oak Ridge, and Dorothy Marcus Gans, who worked as a technician in the Metallurgical Laboratory in Chicago.

    Alfalfa trap crops are currently used to manage Lygus spp. in organic strawberry fields on the California Central Coast. The retention of Lygus spp. in alfalfa creates aggregated distributions that provide improved opportunities for biological control by the introduced parasitoid Peristenus relictus (Ruthe). The abundance and distribution of P. relictus between two trap crops separated by 50 strawberry rows were analyzed in 2008 and 2010. Parasitism of Lygus spp. nymphs by P. relictus (measured by larval abundance and % parasitism) was greatest in alfalfa trap crops compared with strawberry rows. A significantly positive correlation between host nymphs and P. relictus larvae in and between trap crops was found. Movement of P. relictus adults from a marked alfalfa trap crop into adjacent strawberry rows or trap crops was also studied in 2008 and 2009 using a chicken egg-albumin enzyme-linked immunosorbent assay mark-capture technique. In 2008 and 2009, 85 and 49% of protein-marked wasps were captured from central trap crops, respectively, indicating that alfalfa trap crops act as a concentrated "host-density anchor" in organic strawberry fields.

    Langley Research Center has licensed a new high-temperature polyimide with versatile applications to Unitech LLC, of Hampton, Virginia, and J. D. Lincoln, Inc., of Costa Mesa, California. Through a Memorandum of Agreement (MOA) and its license, Unitech, a client of the NASA Hampton Roads Technology Incubator (HRTI), is now selling the new polyimide, better known as RP46. Dr. Ruth Pater, of NASA Langley, developed RP46 for aerospace applications. The material was designed for re-entry vehicles and high-temperature engine components; however, its versatile nature makes it applicable as a molding, adhesive, coating, composite matrix resin, foam, or film. Available in liquid and powder forms, RP46 can also be fabricated over mesh for use in molds. RP46 presents a profitable option to manufacturers, because the ease of manufacturing the resin and the reduction in curing time saves money. Consumers save money because RP46 is more durable than similar products that are susceptible to microcracking when used as a coating or adhesive in high-temperature situations and often required reapplication. The chances of microcracking are significantly reduced with RP46 because of its unsurpased ability to resist heat and corrosion.

    After incidental exposure to Blacks who succeeded in counterstereotypical domains (e.g., Brown University President Ruth Simmons, Nobel Laureate Toni Morrison), participants drew an automatic inference that race was not a success-inhibiting factor in modern society. Of note, participants' automatic inferences were not simply guided by their explicit reasoning (i.e., their beliefs about what these exemplars signify about the state of race relations). Studies 1-3 demonstrated the basic automatic inference effect and provided evidence that such effects unfolded automatically, without intention or awareness. Study 4 replicated the effect in non-race-related domains. Subsequent studies examined what features of exemplars (Studies 5 and 6) and inference makers (Studies 7 and 8) prompt automatic inferences. Study 5 suggested that counterstereotypically successful exemplars prompt racism-denying inferences because they signal what is possible, even if not typical. Study 6 demonstrated that when these exemplars succeed in a stereotypical domain (e.g., Blacks in athletics), similar automatic inferences are not drawn. Those most likely to draw automatic inferences are people predisposed to approach the world with inferential thinking: participants dispositionally high in need for cognition (Study 7) or experimentally primed to think inferentially (Study 8).

  20. A four-fold humanity: Margaret Mead and psychological types.

    Sullivan, Gerald

    Beginning in 1933, while working in New Guinea, Margaret Mead developed her so-called squares hypothesis. Mead never published its terms, though she made a brief comment on it in her autobiography, Blackberry Winter (1972), and the arguments found in Sex and Temperament in Three Primitive Societies (1935) and the research leading to Balinese Character (Bateson & Mead, 1942) bore its imprint. Beginning with William McDougall's distinction between temperament (innate predispositions) and character (learned organization of habit), Mead articulated a morphological approach to the interplay between biology and culture that yielded four primary and four intermediary personality types. Under specified but not inevitable circumstances, the conscious choices of a given people could render one or another of these types characteristic or predominantly stable within their population, giving each of the other types a definite relation to the dominant type and thereby the cultural ethos of its society. Persons of each type followed a developmental path specific to their type different both from that of other types and in its manifestations given the various relations of the individual's type to the dominant type. Mead's hypothesis was, therefore, a vision of the unity and diversity of a single human species as well as an approach to the differing psychological positioning of individuals in cultures. In examining Mead's hypothesis, this essay also takes up Mead's debts to several leading psychologists (McDougall, C. G. Jung, and Erik Erikson), and (provisionally) how her vision differed from that of Ruth Benedict. PMID:15048668

    The relationship between maternal-infant interaction and attachment quality to infant developmental outcomes has long been established. As children mature, problems stemming from troubled caregiver-infant relations may result in referral to mental health or child protection services. The accurate and appropriate assessment of attachment is critical for early recognition of problematic relations and for informing suitable treatment modalities. Evaluating the quality of attachment poses a challenge for researchers and clinicians seeking to explore the association between infant development and the quality of early caregiving experiences. Although providing a definitive answer to the question of which of these assessment procedures is the single universal standard for measuring attachment quantity is beyond the scope of this article, readers will be provided with a description and comparison of strengths and limitations of the most commonly used measures of attachment, including the Strange Situation Procedure (M.D.S. Ainsworth, M.C. Blehar, E. Waters, & S. Wall, 1978), Attachment Q-Sort (E. Waters & K.E. Deane, 1985), Toddler Attachment Sort (TAS-45; J. Kirkland, D. Bimler, A. Drawneek, M. McKim, & A. Scholmerich, 2004), CARE-Index (P. Crittenden, 1985), Atypical Maternal Behavior Instrument for Assessment and Classification (AMBIANCE; E. Bronfman, E. Parsons, & K. Lyons-Ruth, 1999), Massie-Campbell Scale of Mother-Infant Attachment Indicators During Stress Scale (Attachment During Stress Scale; H.N. Massie & B.K.

    VeriFax, founded in 1990 by Dr. Ruth Shrairman and Mr. Alex Landau, began operations with the aim of developing a biometric tool for the verification of signatures from a distance. In the course of developing this VeriFax Autograph technology, two other related applications for the technologies under development at VeriFax became apparent. The first application was in the use of biometric measurements as clinical monitoring tools for physicians investigating neuromuscular diseases (embodied in VeriFax's Neuroskill technology). The second application was to evaluate persons with critical skills (e.g., airline pilots, bus drivers) for physical and mental performance impairments caused by stress, physiological disorders, alcohol, drug abuse, etc. (represented by VeriFax's Impairoscope prototype instrument). This last application raised the possibility of using a space-qualified Impairoscope variant to evaluate astronaut performance with respect to the impacts of stress, fatigue, excessive workload, build-up of toxic chemicals within the space habitat, etc. The three applications of VeriFax's patented technology are accomplished by application-specific modifications of the customized VeriFax software. Strong commercial market potentials exist for all three VeriFax technology applications, and market progress will be presented in more detail below.

    An essential component of shorebird conservation is identifying, protecting, and managing high-priority stopover sites and migration habitats crucial to the long-term persistence of migrating shorebirds. Because of the tremendous variability in migrant shorebird occurrence patterns in the Prairie Pothole Region of the U.S. (Skagen 1997), it is labor- and cost-intensive to locate the majority of sites used heavily by shorebirds in any one migration period. Because WSR-88D (Weather Surveillance Radar – 1988 Doppler) or NEXRAD (NEXt generation weather RADar) has been useful for locating migrating birds and revealing migration patterns and important roosting sites of some species (e.g., Diehl and others 2003, Gauthreaux and Belser 2003), we undertook a pilot field study to determine wheTHER it also might be feasible to use NEXRAD for locating important stopover sites used by migrating shorebirds in the prairie potholes landscape. Coordinated efforts to advance the applicability of radar technology to bird conservation are underway (Ruth and others 2005).

    The increasing popularity and use of dietary supplements has required health care professionals to become more knowledgeable of their properties, interactions, and adverse effects. The objectives of this review were to evaluate the safety of popular dietary supplements in breastfeeding mothers and the effects on the infants. Nine of the most popular herbal dietary supplements were identified based on the 2011 US market report of the top 10 selling botanicals and the most frequently received inquiries by the Ruth A. Lawrence Lactation Study Center at the University of Rochester Medical Center. Relevant publications were identified through June 2014 using PubMed and EMBASE; tertiary references, including the Drugs and Lactation Database and Natural Medicine Comprehensive Database, were also reviewed. These herbals include black cohosh, cranberry, echinacea, evening primrose, garlic, ginseng, melatonin, milk thistle, and St John's wort. Studies varied greatly with regard to study design, herbal intervention, and outcome measures. Findings suggested that dietary/herbal supplements have not been evaluated in high-quality clinical trials, and there is limited evidence supporting safety of use, particularly among lactating women. Therefore, it is essential for physicians to provide counseling for nursing mothers seeking information on dietary supplements, highlighting reliable safety profiles, inquiring about the potential benefits the patient is seeking, and assessing the patient's perception of this supplement during breastfeeding. More research and clinical trials are required in this area to guide the recommendations and expand our current knowledge of these products. PMID:25881578

  5. Health care law versus constitutional law.

    National Federation of Independent Business v. Sebelius, the Supreme Court's ruling on the Patient Protection and Affordable Care Act, is a landmark decision - both for constitutional law and for health care law and policy. Others will study its implications for constitutional limits on a range of federal powers beyond health care. This article considers to what extent the decision is also about health care law, properly conceived. Under one view, health care law is the subdiscipline that inquires how courts and government actors take account of the special features of medicine that make legal or policy issues especially problematic - rather than regarding health care delivery and finance more generically, like most any other economic or social enterprise. Viewed this way, the opinions from the Court's conservative justices are mainly about general constitutional law principles. In contrast, Justice Ruth Bader Ginsburg's dissenting opinion for the four more liberal justices is just as much about health care law as it is about constitutional law. Her opinion gives detailed attention to the unique features of health care finance and delivery in order to inform her analysis of constitutional precedents and principles. Thus, the Court's multiple opinions give a vivid depiction of the compelling contrasts between communal versus individualistic conceptions of caring for those in need, and between health care and health insurance as ordinary commodities versus ones that merit special economic, social, and legal status.

Proceedings of the 4th Red-cockaded woodpecker Symposium. Ralph Costa and Susan J. Daniels, eds. Savannah, Georgia. January, 2003. Chapter 8. Cavities, Cavity Trees, and Cavity Communities. Pp 501-502. Abstract: Southern flying squirrels can significantly impact red-cockaded woodpecker reproductive success (Laves and Loeb 1999). Thus exclusion or removal of flying squirrels from red-cockaded woodpecker cavities and clusters may be warranted in small woodpecker populations (U.S. Fish and Wildlife Service 2003). However, development of effective and efficient protocols for southern flying squirrel control requires an understanding of the seasonal dynamics of southern flying squirrel cavity use. Most studies of southern flying squirrel use of red-cockaded woodpecker cavities have been conducted during spring (e.g., Harlow and Lennartz 1983, Rudolph et al. 1990a, Loeb 1993) and no studies have examined the effects of long term flying squirrel control on subsequent cavity use. The objectives of this study were to determine: (1) whether flying squirrel use of red-cockaded woodpecker cavities varies with season or cavity type, and (2) the long term effect of continuous squirrel removal.

  8. Hemoglobin and the origins of the concept of allosterism.

    Edsall, J T

    1980-02-01

    Bohr, Hasselbalch, and Krogh (1904) observed both what we now call the cooperative homotropic character of the binding of oxygen by hemoglobin and the heterotropic control exerted by CO2 in diminishing the oxygen affinity. Ten years later Christiansen, Douglas, and Haldane discovered the converse effect of oxygenation in diminishing CO2 uptake. It was then generally believed that hemoglobin contains only a single heme: A. V. Hill, to explain cooperative phenomena, postulated reversible aggregation of these monomer units (1910). After 1924, Adair and Svedberg independently showed that the molecule contained four hemes, and Adair's intermediate compound hypothesis, with four binding constants suitably chosen, could formally explain cooperative binding. Pauling proposed a simple model, involving only two constants, that fitted available data well. Haurowitz's demonstration that crystal structure changed on oxygenation (1938) gave the first evidence clearly pointing to a conformation change; in 1951 Wyman and Allen elaborated the idea in thermodynamic terms, and Perutz's crystallographic studies later revealed in molecular detail the nature of the change associated with ligand binding. The important heterotropic interactions that influence the binding of oxygen, necessarily with reciprocal interactions between oxygen binding and the uptake of the heterotropic ligands, are of three kinds: 1) proton binding by the "Bohr groups," 2) direct binding of CO2 as carbamate, and 3) binding of organic phosphate anions, such as diphosphoglycerate. The last of these, although fully as important as the first two, was not discovered for about half a century after the early work. Some major discoverers in the unraveling of these complicated relations were D. D. Van Slyke, F. J. W. Roughton, Linus Pauling, J. Wyman, and later Ruth and Reinhold Benesch, L. Rossi-Bernardi, and J. V. Kilmartin. All these, and numerous others, contributed to our understanding of both homogropic and

    Legal requirements on space and dimensions regarding furnished cages and alternative systems in laying hen husbandry are subject of constant discussion. Further knowledge about basic measures of the hens might help to come to reasonable results in the future. Digital images of Lohmann Selected Leghorn (LSL) and Lohmann Brown (LB) laying hens, housed at the Lehr- und Forschungsgut Ruthe, University for Veterinary Medicine Hanover, Foundation, in Big Dutchman Eurovent laying hen cages, were made at three stages (19th, 36th and 58th week) of production. All hens had been taken out of their cages by night and set on a perch in a special cage used to photograph the hens frontally under controlled conditions. Body widths were calculated by a python application Cdisto.py0 2009 Andreas Briese) to mark and measure the body width in the digital images of a total of 156 hens. Mean body widths of 133.77 mm in Lohmann-LSL hens (SD = 9.71; N = 64; mean weight: 1.73 kg) and of 152.55 mm in Lohmann-LB hens (SD = 10.31; N = 92; mean weight: 1.93 kg) respectively were found. Even slight changes in body weights had no effect on the body width. Nonetheless the differences between both hybrids were always statistically significant (Mann-Whitney p < 0,001). Using these preliminary results on body width in a mathematical model simultanious feeding behaviour becomes only possible if the number of animals is reduced by 10.3% to 89.7% in LSL and by 21.3% to 78.7% in LB breeds in relation to a calculated maximum on base of the minimum space requirements for furnished cages in the EU-Dir 74/1999/EC.

    The World Health Organization has announced that within 3 years 10% of Tanzania's population of 26 million will be infected with the human immunodeficiency virus (HIV). But there is some faint hope in the research of Tanzanian traditional medicine. An almost 90-year-man, Waziri Mrisho, is credited with having treated AIDS patients successfully with herbs that strengthen the immune system. Margaret Nakamya was stricken by the symptoms of AIDs in March 1990. She was referred to Waziri and started using his herbs. 3 years later she weighs 49 kg compared to 40 kg before. The old man's son set up a little factory where he pulverizes herbs and sells them at the price he can command The 3 types of trees that the herbal medicine is taken from grow in the wild, but some have also been planted around the factory. Even if these herbs are effective, it will take years before the AIDS epidemic is over, when people have changed their lifestyles. The means of communication (TV, cinema, radio, telephone) are missing or inadequate. In the Kagera region, with 1.2 million inhabitants, 25% of pregnant women are HIV-infected and 65,000 children lost their parents to AIDS. There are 2000 children in Dar Es Salaam living in the streets. The Anglican St. Albans Church runs a center for street kids where they get meals 3 times a week. The nurse Ruth Nesje enlisted a Norwegian physician and homeopath in a research project involving 30 AIDS patients in Norway. The University in Bergen will do in vitro testing. One group of patients will receive both AZT and the herbs, another group will get only AZT, and the 3rd group will obtain only the herbs. The Norwegian Nursing Association, NORAD, and DANIDA also plan various projects in the Tanga region. PMID:8499187

    Approximately sixty years ago, the Savannah River Site (SRS) was built to produce nuclear materials. SRS production operations impacted air, soil, groundwater, ecology, and the local environment. Throughout its history, SRS has addressed these contamination issues directly and has maintained a commitment to environmental stewardship. The Site boasts many environmental firsts. Notably, SRS was the first major Department of Energy (DOE) facility to perform a baseline ecological assessment. This pioneering effort, by Ruth Patrick and the Philadelphia Academy of Sciences, was performed during SRS planning and construction in the early 1950's. This unique early generation of work set the stage for subsequent efforts. Since that time, the scientists and engineers at SRS pro-actively identified environmental problems and developed and implemented effective and efficient environmental management and remediation solutions. This second generation, spanning the 1980's through the 2000's, is exemplified by numerous large and small cleanup actions to address metals and radionuclides, solvents and hydrocarbons, facility and area decommissioning, and ecological restoration. Recently, a third generation of environmental management was initiated as part of Enterprise SRS. This initiative to 'Develop and Deploy Next Generation Cleanup Technologies' formalizes and organizes the major technology matching, development, and implementation processes associated with historical SRS cleanup success as a resource to support future environmental management missions throughout DOE. The four elements of the current, third generation, effort relate to: 1) transition from active to passive cleanup, 2) in situ decommissioning of large nuclear facilities, 3) new long term monitoring paradigms, and 4) a major case study related to support for recovery and restoration of the Japanese Fukushima-Daiichi nuclear power plant and surrounding environment.

This year more than 60 doctoral students and postdocs from over 25 different groups working in German university hospitals or research institutes attended the meeting to discuss their latest findings in the fields of neuroimmunology, neurodegeneration and neurovascular research. All participants appreciated the stimulating environment in Motzen, Brandenburg, and people took the opportunity for scientific exchange, discussion about ongoing projects and already started further collaborations. Like in the previous years, the symposium was regarded as a very well organized platform to support research of young investigators in Germany. According to the major aim of NEUROWIND e.V. to support younger researchers in Germany the 3rd NEUROWIND YOUNG SCIENTIST AWARD for experimental neurology was awarded to Ruth Stassart working in the group of Klaus Armin Nave and Wolfgang Brück (MPI Göttingen and Department of Neuropathology, Göttingen Germany). The successful work was published in Nature Neuroscience entitled “A role for Swann cell-derived neuregulin-1 in remyelination”. This outstanding paper deals with the function of Schwann cell neuregulin as an endogenous factor for myelin repair. The award is endowed with 20.000 Euro sponsored by Merck Serono GmbH, Darmstadt, Germany (unrestricted educational grant). This year’s keynote lecture was given by Albert Ludolph, Head of the Department of Neurology at the University Clinic of Ulm. Dr. Ludolph highlighted the particular role of individual scientists for the development of research concepts in Alzheimer´s disease (AD) and frontotemporal dementia (FTD). PMID:24330587

    The electrochemical oxidation, in aqueous medium, of a 3,4-ethylenedioxythiophene monomer functionalized by a sulfonate group exhibiting cation-exchange properties, allows the synthesis of a new type of water-soluble material. In order to synthesize in water, by oxidative electropolymerization, polymer films of controlled thickness containing attached sulfonate groups, we have investigated the polymerization of the functionalized monomer in the presence of the unsubstituted one without supporting electrolyte. Using an equimolar mixture (0.01 mol/l) of both monomers, copolymers exhibiting cation exchange abilities have been synthesized. As an example, th easy incorporation of hexaamine-ruthenium(III) into one of these copolymers is briefly reported. L'oxydation électrochimique en milieu aqueux d'un monomère de type 3,4- éthylènedioxythiophène fonctionnalisé par un groupement sulfonate permet d'envisager la synthèse d'un nouveau type de polymère hydrosoluble. Afin d'obtenir électrochimiquement en milieu aqueux, un film de polymère d'épaisseur contrôlée contenant des groupements sulfonates, nous avons evisagé de polymériser ce monomère en présence de son homologue non substitué. En partant d'un mélange équimolaire (0.01 mol/l) des deux monomères et en l'absence d'électrolyte support, nous avons synthétisé un matériau possédant des propriétés d'échange de cations. A titre d'exemple, nous présentons brièvement l'incorporation d'un complexe hexaaminé du ruthénium(III) dans un de ces copolymères.

High Alt Med Biol 15:388–395, 2014.—Lipid metabolism under chronic hypoxia (CH) has not received equal attention as intermittent hypoxia (IH). To determine the CH-induced changes in plasma and liver, as well as the mRNA and protein expression of two key enzymes in the triglyceride and cholesterol biosynthesis pathways, SREBP-1 (HMG-CoA reductase) and SREBP-2 (SCD-1), we exposed adult male Wistar rats to CH (4600 m; n=15) for 30 days compared to normoxic rats (n=15). The CH rats exhibited weight loss (p<0.001), higher hematocrit (%), and higher hemoglobin (g/dL) (p<0.01). In the plasma of CH rats, total cholesterol and LDL-cholesterol increased at day 15. VLDL-cholesterol and triglycerides (p<0.01) greatly increased (35%), while HDL-cholesterol decreased (p<0.01). Triglycerides and VLDL-cholesterol remained elevated by 28% at day 30 (p<0.01). Hepatic triglycerides increased two-fold, while total cholesterol increased by 51% (p<0.001; p<0.05). Upregulation of SCD-1 mRNA and protein was observed in the CH rats (p<0.01); however, no differences were observed in HMG-CoA reductase mRNA or protein expression in both groups. In conclusion, CH, like IH, alters lipid profiles by increasing triglycerides in the plasma and liver and upregulating triglyceride biosynthesis without affecting the cholesterol biosynthetic pathway. Additional involved mechanisms require further study because of the importance of lipids in cardiovascular risk. PMID:25185022

    Abstract Abuse is highly prevalent among HIV+ women, leading to behaviors, including lower adherence to highly active antiretroviral therapy (HAART) that result in poor health outcomes. Resilience (functioning competently despite adversity) may buffer the negative effects of abuse. This study investigated how resilience interacted with abuse history in relation to HAART adherence, HIV viral load (VL), and CD4+ cell count among a convenience sample of 138 HIV+ women from the Ruth M. Rothstein CORE Center/Cook County Health and Hospital Systems site of the Women's Interagency HIV Study (WIHS). Resilience was measured by the 10-item Connor-Davidson Resilience Scale (CD-RISC). HAART adherence (≥95% vs. <95% self reported usage of prescribed medication) and current or prior sexual, physical, or emotional/domestic abuse, were reported during structured interviews. HIV viral load (≥20 vs. <20 copies/mL) and CD4+ count (200 vs. <200 cells/mm) were measured with blood specimens. Multiple logistic regressions, controlling for age, race, income, enrollment wave, substance use, and depressive symptoms, indicated that each unit increase in resilience was significantly associated with an increase in the odds of having ≥95% HAART adherence and a decrease in the odds of having a detectable viral load. Resilience-Abuse interactions showed that only among HIV+ women with sexual abuse or multiple abuses did resilience significantly relate to an increase in the odds of ≥95% HAART adherence. Interventions to improve coping strategies that promote resilience among HIV+ women may be beneficial for achieving higher HAART adherence and viral suppression. PMID:24568654

  19. America's energy famine: its cause and cure

    SciTech Connect

    Knowles, R.S.

    1980-01-01

    In this book Ruth Sheldon Knowles, an internationally recognized petroleum specialist, clarifies the domestic and foreign issues which underlie the current oil famine and spells out the hard choices the American public faces on energy priorities in the near future. She explains how we came to be so dependent on foreign, including Arab, oil and discusses the corporate, national, and international policies that lie behind our current energy crisis. Although the decisions are not simple, Ms. Knowles firmly believes that self-sufficiency is not a dim hope but a clear possibility, as alternate sources of energy are developed and discovered. But she makes equally clear that, until the end of this century, the economy of the US requires an adequate supply of oil and gas and that such a supply cannot be achieved unless further oil discovery is encouraged. Geologists estimate that, with present technology, as much oil and gas remains to be discovered in the US both on- and offshore, as has been found in the last hundred years. Its discovery depends upon economic incentive and access to these resources, since half of our energy potential lies under federal and state lands. The immediate development of coal reserves, nuclear technology, and synthetic fuels involves controversial public policy. This book details the way new technology can reconcile essential energy resource development with the maintenance and improvement of the quality of our environment. It examines the roles of conservation and of solar energy, the timetable for America's energy self-sufficiency, and the politics and economics of today's energy problems.

  20. Where are you sucking from? Using Stable Isotopes to understand Host Specificity in two Hemiparasitic plants above the tree line in Northern Sweden

    2012-12-01

    By Alejandro Macias, Erik Hobbie, Ruth Varner, Kaitlyn Steele Hemiparasites are known to suck nutrients from nearby plants but their host specificity is not well understood. Hemiparasites are ecosystem engineers, limiting surrounding plant's growth, and decreasing local biodiversity. To better understand this phenomenon, the host specificities of two hemiparasitic angiosperms, Bartsia alpina , and Pedicularis lapponica were studied above the tree line along an elevational gradient in Sweden. B. alpina specialized in wetter environments, as indicated by their higher δ13C signature, and their growth among Salixsp.Betula nana, Bistorta vivipara, Viola biflora, Geranium sp., and Trollious europaeus. P. lapponica was common in drier, less species rich environments, known as heaths, where B. nana, Empetrum negrum, Phyllodoce coeruela, Vaccinium myrtillus and Vaccinium vitis-idaea are the most common species. P. lapponica had higher foliage δ13C due to its better water-use efficiency in a dry environment. Field survey data and δN15 values of both the foliage of the parasitic plants and their potential hosts were used to determine host specificity. Since the δN15 value of the hemiparasitic plant and its host are similar due to parasitism, it was determined that P. lapponica had a preference for plants with an ericoid mycorrhizal association, such as Vaccinium sp, and E. negrum, but not for the common P. coeruela. This does not support the idea found in the literature that P. lapponica has a preference for grasses. B. alpina was less host specific, associating with non-mycorrhizal, ericoid, and ectomycorhizal plants, such as Carex sp, Vaccinium sp., and S. lapponum. The ectomycorrhizal species, Salix sp., and B. nana, were both potential hosts for B. alpina and P. lapponica due to their presence among them. However, the isotopic data revealed that B. alpina had a preference for Salix sp., and P. lapponica had a preference for B. nana.

    At first, few constitutional experts took seriously the argument that the Patient Protection and Affordable Care Act exceeded Congress's power under the commerce clause. The highly political opinions of two federal district judges - carefully chosen by challenging plaintiffs - of no particular distinction did not shake that confidence that the act was constitutional. This disdain for the challengers' arguments was only confirmed when the act was upheld by two highly respected conservative court of appeals judges in two separate circuits. But after the hostile, even mocking questioning of the government's advocate in the Supreme Court by the five Republican-appointed justices, the expectation was that the act would indeed be struck down on that ground. So it came as no surprise when the five opined the act did indeed exceed Congress's commerce clause power. But it came as a great surprise when Chief Justice John Roberts, joined by the four Democrat-appointed justices, ruled that the act could be sustained as an exercise of Congress's taxing power - a ground urged by the government almost as an afterthought. It was further surprising, even shocking, that Justices Antonin Scalia, Anthony Kennedy, Clarence Thomas, and Samuel Alito not only wrote a joint opinion on the commerce clause virtually identical to that of their chief, but that in writing it they did not refer to or even acknowledge his opinion. Finally surprising was the fact that Justices Ruth Bader Ginsburg and Stephen Breyer joined the chief in holding that aspects of the act's Medicaid expansion were unconstitutional. This essay ponders and tries to unravel some of these puzzles. PMID:23262769

    Background Improved retention-in-care may enhance health outcomes for people living with HIV/AIDS (PLWHA). While laboratory surveillance data may be used to gauge retention, no previous reports have compared surveillance lab vs. clinic visit-based measures of retention-in-care. We compared lab surveillance vs. clinic visit-based approaches for identifying retention status for PLWHA. Methods We examined 2011 patient visit data from the Ruth M. Rothstein CORE Center, Cook County's HIV clinic. We defined retained patients as those with visits every 6 months over 2 years and matched patients classified via visit data against HIV surveillance labs reported to the Chicago Department of Health. We determined the sensitivity, specificity and receiver operator characteristics of varying lab surveillance vs. clinic visit measures of retention. Results Of patients classified via clinic visit data, 91% of 1,714 in-care vs. 22% of 200 out-of-care patients met our most stringent surveillance based retention definition – having ≥ 2 viral load/CD4s performed 90 days apart reported by the same laboratory in 2011. Of surveillance lab-based definitions for retention, having ≥ 2 HIV viral load and/or CD4 values at least 3 months apart reported from the same facility possessed the best receiver operator parameters and the receiver operator characteristics curve comparing several surveillance lab vs. clinic-visit based retention measures had an area under the curve of 0.95. Discussion Our findings demonstrate that surveillance laboratory data can be used to assess retention-in-care for PLWHA. These data suggest that bi-directional data sharing between public health entities and care providers could advance re-engagement efforts. PMID:25867775

    The Looking for Life in Extreme Environments workshop held at Indiana University Bloomington in July of 2009 was the first in a series of workshops for high-school teachers that are currently in development. The workshops' modules are based on the research of faculty members in the Departments of Geological Sciences, Biology, and Astronomy, the School of Education, and the School of Public and Environmental Affairs at Indiana University Bloomington; the modules use lessons from Exploring Deep-Subsurface Life. Earth Analogues for Possible Life on Mars: Lessons and Activities, curricular materials that were produced and edited by Lisa Pratt and Ruth Droppo and published by NASA in 2008. Exploring Deep-Subsurface Life is a workbook, a DVD (with closed-captioning), and a CD with the lessons in digital text format for adaptation to classroom needs and printing. Each lesson includes the National Education Standards that apply to the materials. The workbook's lessons are written with three considerations: Life Domains, Cellular Metabolism, and Extreme Environments and Microbes. Students are challenged to build, draw, measure, discuss, and participate in laboratory processes and experiments that help them understand and describe microbes and their environments. In the Capstone, the students write a grant proposal based on the three lessons' analogues. The DVD is collection of videotaped interviews with scientists in laboratories at Michigan State, Princeton, and Indiana University, who are working on water and gas samples they collected from deep gold mines in South Africa and the Canadian Arctic. The interview materials and some animated graphics are compiled into four video pieces that support and compliment the accompanying workbook lessons and activities, and offer students insight into the excitement of scientific discovery.

  4. Student performance in computer modeling and problem solving in a modern introductory physics course

    NASA Astrophysics Data System (ADS)

    Kohlmyer, Matthew Adam

    Matter & Interactions, an innovative introductory physics curriculum developed by Ruth Chabay and Bruce Sherwood, emphasizes computer modeling and fundamental physical principles. Two think-aloud protocol studies were conducted to investigate the performance of students from this curriculum in solving physics problems that require computer modeling. Experiment 1 examined whether Matter & Interactions students would, given the choice, use computer modeling to solve difficult problems that required predicting motion, and how their solution approaches differed from those of students from a traditional introductory physics course. Though they did not overwhelmingly choose computer modeling, some M&I students did write computer models successfully or apply the iterative algorithm by hand. The solution approaches of M&I students and traditional course students differed qualitatively in their use of the momentum principle and pre-derived special case formulas. In experiment 2, Matter & Interactions students were observed while they wrote programs in the VPython language in order to examine their difficulties with computer modeling. Areas of difficulty included determining initial conditions, distinguishing between simulated time and the time step, and updating momentum and position. Especially troublesome for students was the multistep procedure for calculating a force that changes with time. Students' understanding of the structure of a computer model improved by the end of the semester as shown by their performance on a line sorting task. Students with fewer difficulties proceeded through the computer model in a more linear, straightforward fashion. Instruction was revised based on initial findings from the first phase of the experiment. Students in the second phase of the experiment, who had used the revised instruction, had fewer difficulties on the same tasks, though other factors may have been involved in the improvement.

    NASA Ames Research Center, Moffett Field, CA is the NASA lead Center for rotorcraft research. Rotorcraft research at Ames includes system analysis and configuration optimization, aeromechanics, and flight control and cockpit integration. Research in other areas such as composite structure and material, and rotor acoustics are conducted mainly at Langley Research Center, and rotorcraft propulsion and drivetrain are conducted at Lewis Research Center. This seminar will discuss Ames' rotorcraft research goals and some sample research projects and results. The talk will also briefly describe the newly fanned Army/NASA Rotorcraft Division, which combines the resources of rotorcraft branches in NASA Ames Aeronautics Directorate with Army's Aeroflightdynamics Directorate to better achieve the missions of the two previous rotorcraft research organizations at Ames. Rotorcraft research activities at NASA Ames are funded by two main program categories: Research and Technology (RUTH Base program and the Short Haul (Civil Tiltrotor) program. Work in the R&T program is carried out by the research staff in the Army/NASA Rotorcraft Division, and the work on SH(CT) program is carried out jointly by the SH(CT) program office and the Army/NASA Rotorcraft Division. Sample research projects and results in REST base program, such as conceptual assessment of several high-speed rotorcraft, rotorcraft CFD, individual blade control for reduction of external noise and vibration, noise-abatement flight procedures, engine inoperative procedures, handling qualities, and advanced flight control laws are broadly reviewed. High-speed rotorcraft research related to SH(CT) technology development conducted at Ames in the areas of low-noise proprotor, and low-noise terminal-area operations is also discussed.

    Objective: Neuroleptics were introduced into North America 60 years ago. The credit for this advance is generally accorded to Heinz Lehmann. I sought to explore whether Lehmann really was the first North American psychiatrist to study the effects of chlorpromazine (CPZ) and to provide a more balanced view of its application in a clinical context. Method: I searched for historical documents and published articles in several libraries and interviewed psychiatrists active from 1952–1970. Results: The first article in English was published in the July volume of the Archives of Neurology and Psychiatry in 1954 (n = 71). Another article, written in French by Roland Saucier and published in a journal called Le Saguenay Médical, also described the effects of CPZ on a Canadian psychiatric population in August 1954 (n > 200). However, the first prescription for CPZ was written by Roland Saucier, who brought the product back from Paris after a fellowship there. Ruth Kajander, in Ontario, was also one of the first prescribers of this drug, following her study of its use in anesthesia and a publication in the proceedings of a symposium. Conclusion: The contents of the 2 naturalistic studies were compared. Lehmann’s study started 1 month before that of Saucier. Lehmann was the first North American psychiatrist to publish an article on CPZ, but Roland Saucier nevertheless made an important contribution, being the first to prescribe this drug in North America and reporting results for a study with a sample size 3 times that of Lehmann’s study.

They are oriented N-S to NNE-SSW and NNW-SSE at its northern and southern end, respectively, forming a subtle arc, oblique with respect to the general NW-SE trend of the Iberian Chain. The aim of this work is to characterize with paleomagnetic data the kinematic evolution of the the Altomira Range, located at the southwestern deformation front of the Iberian Chain, and of the structures within its associated piggy-back basin, the Loranca basin. This approach will also give clues regarding the primary and/or secondary origin of these structures to better characterize them in further studies (3D reconstruction and restoration, fault pattern). A total of 180 samples were obtained from 19 sites in Eocene, Oligocene and Miocene rocks (including clays, fine sandstones and limestones). They were analyzed by means of stepwise thermal demagnetization and subsequent measurement of the natural remanent magnetization (NRM). Although fold tests are not statistically significant, a primary origin of the magnetization is deduced by samples showing either normal or reverse polarity after bedding correction of the calculated characteristic components. Declinations of the site mean directions appear scattered after bedding correction suggesting differential vertical-axis rotations. Sites located at the

    2003-01-01

    The Utrecht course ``The Generation and Transport of Radiation'' teaches basic radiative transfer to second-year students. It is a much-expanded version of the first chapter of Rybicki & Lightman's ``Radiative Processes in Astrophysics''. After this course, students understand why intensity is measured per steradian, have an Eddington-Barbier feel for optically thick line formation, and know that scattering upsets LTE. The text is a computer-aided translation by Ruth Peterson of my 1992 Dutch-language course. My aim is to rewrite this course in non-computer English and make it web-available at some time. In the meantime, copies of the Peterson translation are made yearly at Uppsala -- ask them, not me. Eventually it should become a textbook. The Utrecht course ``Radiative Transfer in Stellar Atmospheres'' is a 30-hour course for third-year students. It treats NLTE line formation in plane-parallel stellar atmospheres at a level intermediate between the books by Novotny and Boehm-Vitense, and Mihalas' ``Stellar Atmospheres''. After this course, students appreciate that epsilon is small, that radiation can heat or cool, and that computers have changed the field. This course is web-available since 1995 and is regularly improved -- but remains incomplete. Eventually it should become a textbook. The three Utrecht exercise sets ``Stellar Spectra A: Basic Line Formation'', ``Stellar Spectra B: LTE Line Formation'', and ``Stellar Spectra C: NLTE Line Formation'' are IDL-based computer exercises for first-year, second-year, and third-year students, respectively. They treat spectral classification, Saha-Boltzmann population statistics, the curve of growth, the FAL-C solar atmosphere model, the role of H-minus in the solar continuum, LTE formation of Fraunhofer lines, inversion tactics, the Feautrier method, classical lambda iteration, and ALI computation. The first two sets are web-available since 1998; the third will follow. Acknowledgement. Both courses owe much to previous

    HAMLET (Highly Automated Multimedia Light Enhanced Theatre) was the star performance at the recent finals of the `Young Engineer for Britain' competition, held at the Commonwealth Institute in London. This state-of-the-art computer-controlled theatre lighting system won the title `Young Engineers for Britain 1998' for David Kelnar, Jonathan Scott, Ramsay Waller and John Wyllie (all aged 16) from Merchiston Castle School, Edinburgh. HAMLET replaces conventional manually-operated controls with a special computer program, and should find use in the thousands of small theatres, schools and amateur drama productions that operate with limited resources and without specialist expertise. The four students received a £2500 prize between them, along with £2500 for their school, and in addition they were invited to spend a special day with the Royal Engineers. A project designed to improve car locking systems enabled Ian Robinson of Durham University to take the `Working in industry award' worth £1000. He was also given the opportunity of a day at sea with the Royal Navy. Other prizewinners with their projects included: Jun Baba of Bloxham School, Banbury (a cardboard armchair which converts into a desk and chair); Kobika Sritharan and Gemma Hancock, Bancroft's School, Essex (a rain warning system for a washing line); and Alistair Clarke, Sam James and Ruth Jenkins, Bishop of Llandaff High School, Cardiff (a mechanism to open and close the retractable roof of the Millennium Stadium in Cardiff). The two principal national sponsors of the competition, which is organized by the Engineering Council, are Lloyd's Register and GEC. Industrial companies, professional engineering institutions and educational bodies also provided national and regional prizes and support. During this year's finals, various additional activities took place, allowing the students to surf the Internet and navigate individual engineering websites on a network of computers.

    There is growing evidence that variability in the size and heat content of the tropical Atlantic Warm Pool impacts circum-North Atlantic climate via the Atlantic Multi-decadal Oscillation mode (Wang et al., 2008). The Atlantic Warm Pool spans the Gulf of Mexico, Caribbean Sea and the western tropical North Atlantic. Barbados is located near the center of the tropical Atlantic Warm Pool and coupled ocean models suggest that Barbados remains near the center of the tropical Atlantic Warm Pool under varying wind stress simulations. Measurements of the oxygen isotope paleothermometer in Acropora palmata coral species recovered from cores offshore Barbados, show a 3oC monotonic decrease in sea surface temperature from 13106 ± 83 to 12744 ± 61 years before present (errors given as 2 sigma). This interval corresponds to a sea level rise from 71.4 meters to 67.1 meters below present levels at Barbados. The 3oC temperature decrease is captured in eight A. palmata specimens that are in stratigraphic sequence, 230Th/234U dated, and analyzed for oxygen isotopes. All measurements are replicated. We are confident that this is the warm pool equivalent of the Younger Dryas climate event. The initiation of this temperature drop in the Atlantic Warm Pool predates the Younger Dryas start in Greenland ice cores, reported to start at 12896 ± 138 years (relative to AD 2000) (Rasmussen et al., 2006), while few other Younger Dryas climate records are dated with similar accuracy to make the comparison.

  13. Corporate social responsibility motives and theories evidenced among oilwell drilling firms in Alberta

    NASA Astrophysics Data System (ADS)

    Altvater, Norbert

    This dissertation is a study in conceptual CSR motives and theories prompted by the knowledge that socially active NGOs have tried to influence the CSP of companies in Alberta's oil patch by using media pressure. The focus of the study was narrowed to changing CSP among Alberta's oilwell drilling firms. This permits intensive interviews with the firms' informants. The examination of changing CSP implies a consideration of the pressures that prompt and influence its change, and points this study to firm motives for behaving responsibly. The firms were firstly categorized according to their primary and secondary CSP using 5 dimensions of CSR previously used by The Conference Board of Canada. The study uses CSR motives conceptualized by Ruth Aguilera and her collaborators to assess the firms' CSP using self-assessed CSR motives and observed CSP. At the onset 3 working hypotheses were posited as starting points from which substantiated propositions were developed. Lance Moir's and Elisabet Garriga and Domènec Meld's classifications of CSR theories were used to organize and evaluate the data. A mapping of the motives and theories in respect of the firms' primary and secondary CSR dimensions appears to display correlations between the CSR theories and the conceptualized motives. Nevertheless, for some of the firms none of the motives conceptualized by Aguilera and her collaborators seem to apply. By re-visiting the motives, and examining them more closely, it seems possible refine the conceptualized motives relying more on perceived conceptions, which are at the basis of legitimacy theories, rather than on relational factors to better explain the normative expectations raised. A similar analysis also indicates that the firms' seem to seek economic benefits, social benefits, or a combination of both. The CSP that results is within the same continuum; the resulting CSP for the firms seems to mediate towards a blend of both, regardless of the original CSR motives. These

    A previous paper (Unsal, E.; Mason, G.; Ruth, D. W.; Morrow, N. R. J. Colloid Interface Sci. 2007, 315, 200-209) reported experiments involving counter-current spontaneous imbibition into a model pore system consisting of a rod in an angled slot covered by a glass plate. Such an arrangement gives two tubes with different cross-sections (both size and shape) with an interconnection through the gap between the rod and the plate. In the previous experiments, the wetting phase advanced in the small tube and nonwetting phase retreated in the large tube. No bubbles were formed. In this paper, we study experimentally and theoretically the formation of bubbles at the open end of the large tube and their subsequent snap-off. Such bubbles reduce the capillary back pressure produced by the larger tube and can thus have an effect on the local rate of imbibition. In the model pore system, the rod was either in contact with the glass, forming two independent tubes, or the rod was spaced from the glass to allow cross-flow between the tubes. For small gaps, there were three distinct menisci. The one with the highest curvature was between the rod and the plate. The next most highly curved was in the smaller tube, and the least highly curved meniscus was in the large tube and this was the tube from which the bubbles developed. The pressure in the dead end of the system was recorded during imbibition. Once the bubble starts to form outside of the tube, the pressure drops rapidly and then steadies. After the bubble snaps off, the pressure rises to almost the initial value and stays essentially constant until the next bubble starts to form. After snap-off, the meniscus in the large tube appears to invade the large tube for some distance. The snap-off is the result of capillary instability; it takes place significantly inside the large tube with flow of wetting phase moving in the angular corners. As imbibition into the small tube progresses, the rate of imbibition decreases and the

  18. Polyimide Resins Resist Extreme Temperatures

    NASA Technical Reports Server (NTRS)

    2009-01-01

    Spacecraft and aerospace engines share a common threat: high temperature. The temperatures experienced during atmospheric reentry can reach over 2,000 F, and the temperatures in rocket engines can reach well over 5,000 F. To combat the high temperatures in aerospace applications, Dr. Ruth Pater of Langley Research Center developed RP-46, a polyimide resin capable of withstanding the most brutal temperatures. The composite material can push the service temperature to the limits of organic materials. Designed as an environmentally friendly alternative to other high-temperature resins, the RP-46 polyimide resin system was awarded a 1992 "R&D 100" award, named a "2001 NASA Technology of the Year," and later, due to its success as a spinoff technology, "2004 NASA Commercial Invention of the Year." The technology s commercial success also led to its winning the Langley s "Paul F. Holloway Technology Transfer Award" as well as "Richard T. Whitcom Aerospace Technology Transfer Award" both for 2004. RP-46 is relatively inexpensive and it can be readily processed for use as an adhesive, composite, resin molding, coating, foam, or film. Its composite materials can be used in temperatures ranging from minus 150 F to 2,300 F. No other organic materials are known to be capable of such wide range and extreme high-temperature applications. In addition to answering the call for environmentally conscious high-temperature materials, RP-46 provides a slew of additional advantages: It is extremely lightweight (less than half the weight of aluminum), chemical and moisture resistant, strong, and flexible. Pater also developed a similar technology, RP-50, using many of the same methods she used with RP-46, and very similar in composition to RP-46 in terms of its thermal capacity and chemical construction, but it has different applications, as this material is a coating as opposed to a buildable composite.

    Methane fluxes emitted by a grazed meadow were measured continuously during the 2012 grazing season at the Dorinne Terrestrial Observatory (50° 18' 44" N; 4° 58' 07" E; 248 m asl.) in Belgium. Measurements were made with the eddy covariance technique, using a fast CH4 analyzer (Picarro G2311-f). Carbon dioxide fluxes (LI-7000) and various micro-meteorological and soil variables, biomass growth and stocking rate evolution were also measured at the site. The site is an intensively pastured meadow of 4.2 ha managed according to the regional usual practices where up to 30 cows are grazing simultaneously. N2O emissions are currently measured through dynamic closed chambers (Beekkerk van Ruth et al., Geophysical Research Abstracts. Vol. 15, EGU2013-3211, 2013) and the carbon budget of the site has already been investigated (Jerome et al. Geophysical Research Abstracts, Vol. 15, EGU2013-6989, 2013). As no CH4 measurements were available, CH4 fluxes were estimated on the basis of dry matter intake by the cows and a conversion factor obtained from a literature review. We want to improve this estimation by measuring CH4 fluxes, identifying their main environmental drivers and understanding diurnal and annual exchange patterns. Methane emissions were found strongly related with cattle stocking rate with a slope of 7.34±0.78 mol CH4 day-1 LSU-1. Up to now, no methane absorption has been observed, the meadow behaving as a methane emitter, even in the absence of cows. In the absence of cows, no significant relation can be established up to now between methane emissions and environmental parameters. No clear diurnal evolution is observed, neither during grazing periods nor during cow free periods. During cow presence periods, fluxes are highly variable, probably due to cow movements in and out the measurement footprint and cow digestion rhythm. Further developments are ongoing in order to improve cattle geo-localization through individual home-made GPS devices and infra

  1. Flow instabilities of Alaskan glaciers

    NASA Astrophysics Data System (ADS)

    Turrin, James Bradley

    Over 300 of the largest glaciers in southern Alaska have been identified as either surge-type or pulse-type, making glaciers with flow instabilities the norm among large glaciers in that region. Consequently, the bulk of mass loss due to climate change will come from these unstable glaciers in the future, yet their response to future climate warming is unknown because their dynamics are still poorly understood. To help broaden our understanding of unstable glacier flow, the decadal-scale ice dynamics of 1 surging and 9 pulsing glaciers are investigated. Bering Glacier had a kinematic wave moving down its ablation zone at 4.4 +/- 2.0 km/yr from 2002 to 2009, which then accelerated to 13.9 +/- 2.0 km/yr as it traversed the piedmont lobe. The wave first appeared in 2001 near the confluence with Bagley Ice Valley and it took 10 years to travel ~64 km. A surge was triggered in 2008 after the wave activated an ice reservoir in the midablation zone, and it climaxed in 2011 while the terminus advanced several km into Vitus Lake. Ruth Glacier pulsed five times between 1973 and 2012, with peak velocities in 1981, 1989, 1997, 2003, and 2010; approximately every 7 years. A typical pulse increased ice velocity 300%, from roughly 40 m/yr to 160 m/yr in the midablation zone, and involved acceleration and deceleration of the ice en masse; no kinematic wave was evident. The pulses are theorized to be due to deformation of a subglacial till causing enhanced basal motion. Eight additional pulsing glaciers are identified based on the spatiotemporal pattern of their velocity fields. These glaciers pulsed where they were either constricted laterally or joined by a tributary, and their surface slopes are 1-2°. These traits are consistent with an overdeepening. This observation leads to a theory of ice motion in overdeepenings that explains the cyclical behavior of pulsing glaciers. It is based on the concept of glaciohydraulic supercooling, and includes sediment transport and erosion

  2. K-12 educational outcomes of immigrant youth.

    The children from immigrant families in the United States make up a historically diverse population, and they are demonstrating just as much diversity in their experiences in the K-12 educational system. Robert Crosnoe and Ruth López Turley summarize these K-12 patterns, paying special attention to differences in academic functioning across segments of the immigrant population defined by generational status, race and ethnicity, and national origin. A good deal of evidence points to an immigrant advantage in multiple indicators of academic progress, meaning that many youths from immigrant families outperform their peers in school. This apparent advantage is often referred to as the immigrant paradox, in that it occurs despite higher-than-average rates of social and economic disadvantages in this population as a whole. The immigrant paradox, however, is more pronounced among the children of Asian and African immigrants than other groups, and it is stronger for boys than for girls. Furthermore, evidence for the paradox is far more consistent in secondary school than in elementary school. Indeed, school readiness appears to be one area of potential risk for children from immigrant families, especially those of Mexican origin. For many groups, including those from Latin America, any evidence of the immigrant paradox usually emerges after researchers control for family socioeconomic circumstances and youths' English language skills. For others, including those from Asian countries, it is at least partially explained by the tendency for more socioeconomically advantaged residents of those regions to leave their home country for the United States. Bilingualism and strong family ties help to explain immigrant advantages in schooling; school, community, and other contextual disadvantages may suppress these advantages or lead to immigrant risks. Crosnoe and Turley also discuss several policy efforts targeting young people from immigrant families, especially those of Latin

Warner Prize is awarded for achievement in observational or theoretical astrophysics by a young researcher (no more than eight years after their Ph.D.). This years Warner Prize was presented to Ruth Murray-Clay of UC Santa Barbara. For her award lecture, Murray-Clay told us all about planetary system architecture: the number, masses, and orbits of planets in a given system.Ruth Murray-Clay [photo from http://web.physics.ucsb.edu/ ~murray/biocv.html]The underlying question motivating this type of research is: How rare is the Solar System? In other words, how likely is it that a given planetary system will have rocky planets close to their star, gas giants farther out, and ice giants at the outer reaches of the system? Answering this question will help us solve the physics problem of how and where planets form, and will also help us on our search for other planets like Earth.The data on exoplanet population from transit and radial velocity observations and from direct imaging tell us that our Solar System is not common (many systems we observe have much more eccentric gas giants), but that doesnt

    result of a number of summers spent, during her Wellesley years, at the solar observatory at Meudon, near Paris. When she returned to Michigan, Dodson became involved in the study of solar flares, based upon the long series of daily observations made with the tower telescopes at Lake Angelus and the improved spectroscopic equipment developed by Robert McMath, Orren Mohler, Leo Goldberg, Keith Pierce, and others. Her colleague during most of these years was Emma Ruth Hedeman, who co-authored many articles with her. Among her great accomplishments was the Comprehensive Flare Index, a widely used measure of flare activity. A "real live wire" and "a marvelous woman," in the words of students and colleagues, Dodson was also a kind and effective teacher, not at all vain about her accomplishments: She held that solar behavior has a way of making people humble. Dodoson was married to Edmund L. Prince and lived across Lake Angelus from the McMath-Hulbert Observatory; often she sailed to work, a joy denied to almost all other astronomers. During her years at McMath-Hulbert, The University of Michigan was the sole major American research university to have two women holding professorial positions in astronomy: Helen Dodson Prince and Hazel Marie Losh. One of the founding members of the Solar Physics Division, Professor Prince was a major factor in the rise and success of the McMath-Hulbert Observatory, even when, after the 1950s, urban growth and upper Midwestern weather conditions conspired to cripple the advantages the observatory's technologies had once conferred. Her colleagues and students recall her with great respect and affection.

    Nitrate radical (NO3) and dinitrogen pentoxide (N2O5, formed through the reaction of NO3 with NO2 and is a large reservoir for NO3) are two key intermediates components in atmospheric nitrogen chemistry [1]. They affect directly the oxidation capacity of the atmosphere through reaction of NO3 with volatile organic compounds (VOCs). It's highly desirable to be able to perform in-situ, simultaneous and continuous monitoring of NO3 and N2O5 concentrations with high selectivity and fast response time. N2O5 is usually indirectly measured via optical measurement of NO3 after thermal dissociation of N2O5 to NO3 [2]. In this paper, we report on the recent development and application of optical method for in situ direct concentration measurements of NO3 and N2O5 in smog chamber. NO3 (as well as NO2) were simultaneously measured by open-path incoherent broadband cavity enhanced absorption spectroscopy (IBBCEAS) [3] based on a light emitted diode operating in the range of 635-675 nm, and N2O5 was monitored by means of open-path multi-pass absorption spectroscopy of an external cavity quantum cascade laser tunable from 1223 to 1263 cm-1 (~8 µm). Reaction of NO3 with VOCs (such as isoprene, formaldehyde, 2-methoxyphenal) as well as the equilibrium between NO3 and N2O5 during the VOCs oxidation by NO3 radical have been on-line traced with high temporal resolution: 1 s for NO3-NO2 and 25 s for N2O5. Experimental detail and preliminary results will be presented. Our present work demonstrated that modern photonic technologies can provide a direct and highly selective means for chemical kinetic study, for instance, bringing insight into reactive uptake for NO3 and N2O5 on the organic particles [4], which remain still unexplored with few exceptions.

    2007-12-01

    Renowned astronomer and astronomy popularizer Kenneth L. Franklin died early Monday morning, June 18, 2007, in Boulder, Colorado, two weeks after undergoing heart surgery. He was 84 years old. Kenneth Linn Franklin, the only child of Myles and Ruth (Houston) Franklin, was born March 25, 1923 in Alemeda, California. Ken obtained his Ph.D. in astronomy in 1953 at the University of California, Berkeley. From 1954 to 1956 he was a research fellow in radio astronomy at the Department of Terrestrial Magnetism, Carnegie Institution of Washington, DC. While there, he and Bernard F. Burke discovered radio emissions from the planet Jupiter. They announced their find on April 6, 1955, at a meeting of the American Astronomical Society (AAS). In 1956 Ken joined the staff of the American Museum-Hayden Planetarium, where he later served as chairman and chief scientist. Over the course of thirty years he wrote and/or presented innumerable sky shows for the planetarium sky theater, taught popular and technical courses in astronomy, and answered questions from the public. Ken was frequently consulted by local industries engaged in the space program, as well as by the news media and publishers. He was often interviewed on local and national radio and television, especially when a celestial event of special interest was due to occur. On the first page of the November 1966 issue of Sky & Telescope, in comments about the upcoming Leonid meteor shower, Franklin stuck his neck out. Based on some calculations that he'd made, he said he felt we were going to be in for a "interesting display." His was one of the few forecasts that suggested the '66 Leonids might be memorable. As it turned out, he was right — that year observers experienced the now-legendary Leonid meteor storm. From 1973 to 1979, Ken was the AAS's public-affairs officer. For two decades he also served in the society's Harlow Shapley Visiting Lecturer Program, speaking at one or two colleges each year. Ken was an active
