    / This study evaluates the institutional capacity and performance of the Taipei Water Management Commission. The commission, which manages the Taipei Water Special Area-one of 95 such areas in Taiwan and the only one managed by a supervisory agency-has established a record of water conservation that suggests its utility as a model for managing other protected water resources areas in Taiwan. However, its present institutional structure limits its ability deliver on its mandate. The study identifies a number of problems related to the commission's current institutional structure that need to be addressed if the commission is to serve as a viable model for managing other protected water resource areas in Taiwan.KEY WORDS: Water resources management; Commissions; Institutional capacity; Taiwan

  6. Tree-Ring Stable Isotopes Reveal Twentieth-Century Increases in Water-Use Efficiency of Fagus sylvatica and Nothofagus spp. in Italian and Chilean Mountains

    2014-01-01

    Changes in intrinsic water use efficiency (iWUE) were investigated in Fagus sylvatica and Nothofagus spp. over the last century. We combined dendrochronological methods with dual-isotope analysis to investigate whether atmospheric changes enhanced iWUE of Fagus and Nothofagus and tree growth (basal area increment, BAI) along latitudinal gradients in Italy and Chile. Post-maturation phases of the trees presented different patterns in δ13C, Δ13C, δ18O, Ci (internal CO2 concentration), iWUE, and BAI. A continuous enhancement in isotope-derived iWUE was observed throughout the twentieth century, which was common to all sites and related to changes in Ca (ambient CO2 concentration) and secondarily to increases in temperature. In contrast to other studies, we observed a general increasing trend of BAI, with the exception of F. sylvatica in Aspromonte. Both iWUE and BAI were uncoupled with the estimated drought index, which is in agreement with the absence of enduring decline in tree growth. In general, δ13C and δ18O showed a weak relationship, suggesting the major influence of photosynthetic rate on Ci and δ13C, and the minor contribution of the regulation of stomatal conductance to iWUE. The substantial warming observed during the twentieth century did not result in a clear pattern of increased drought stress along these latitudinal transects, because of the variability in temporal trends of precipitation and in specific responses of populations.

    2006-01-01

    The U.S. Geological Survey (USGS) has been working with the Albany Water, Gas, and Light Commission to monitor ground-water quality and availability since 1977. This report presents the findings for July 2005 through June 2006 and summarizes the ground-water and surface-water conditions for 2005. Water levels in 14 wells were continuously monitored in Dougherty County, Georgia. Water levels in 12 of those wells were above normal, one was normal, and one was below normal. Ground-water samples collected from the Upper Floridan aquifer indicate that nitrate levels have increased in 13 wells and decreased in two wells from a year earlier. A sample also was collected from the Flint River. A trilinear diagram showing the percent composition of selected major cations and anions indicates that the ground-water quality of the Upper Floridan aquifer at the Albany wellfield is distinctly different from the water quality of the Flint River. To improve the understanding of the ground-water flow system and nitrate movement in the Upper Floridan aquifer, the USGS is developing a ground-water flow model in the southwest Albany area, Georgia.

  8. Intra- and intervariability in beam data commissioning among water phantom scanning systems.

    Accurate beam data acquisition during commissioning is essential for modeling the treatment planning system and dose calculation in radiotherapy. Although currently several commercial scanning systems are available, there is no report that compared the differences among the systems because most institutions do not acquire several scanning systems due to the high cost, storage space, and infrequent usage. In this report, we demonstrate the intra- and intervariability of beam profiles measured with four commercial scanning systems. During a recent educational and training workshop, four different vendors of beam scanning water phantoms were invited to demonstrate the operation and data collection of their systems. Systems were set up utilizing vendor-recommended protocols and were operated with a senior physicist, who was assigned as an instructor along with vendor. During the training sessions, each group was asked to measure beam parameters, and the intravariability in percent depth dose (PDD). At the end of the day, the profile of one linear accelerator was measured with each system to evaluate intervariability. Relatively very small (SD < 0.12%) intervariability in PDD was observed among four systems at a region deeper than peak (1.5 cm). All systems showed almost identical profiles. At the area within 80% of radiation field, the average, and maximum differences were within ± 0.35% and 0.80%, respectively, compared to arbitrarily chosen IBA system as reference. In the penumbrae region, the distance to agreement (DTA) of the region where dose difference exceed ± 1% was less than 1 mm. Repeated PDD measurement showed small intravariability with SD < 0.5%, although large SD was observed in the buildup region. All four water phantom scanning systems demonstrated adequate accuracy for beam data collection (i.e., within 1% of dose difference or 1 mm of DTA among each other). It is concluded that every system is capable of acquiring accurate beam. Thus the selection

  9. Probabilistic reanalysis of twentieth-century sea-level rise.

    2015-01-22

    Estimating and accounting for twentieth-century global mean sea level (GMSL) rise is critical to characterizing current and future human-induced sea-level change. Several previous analyses of tide gauge records--employing different methods to accommodate the spatial sparsity and temporal incompleteness of the data and to constrain the geometry of long-term sea-level change--have concluded that GMSL rose over the twentieth century at a mean rate of 1.6 to 1.9 millimetres per year. Efforts to account for this rate by summing estimates of individual contributions from glacier and ice-sheet mass loss, ocean thermal expansion, and changes in land water storage fall significantly short in the period before 1990. The failure to close the budget of GMSL during this period has led to suggestions that several contributions may have been systematically underestimated. However, the extent to which the limitations of tide gauge analyses have affected estimates of the GMSL rate of change is unclear. Here we revisit estimates of twentieth-century GMSL rise using probabilistic techniques and find a rate of GMSL rise from 1901 to 1990 of 1.2 ± 0.2 millimetres per year (90% confidence interval). Based on individual contributions tabulated in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change, this estimate closes the twentieth-century sea-level budget. Our analysis, which combines tide gauge records with physics-based and model-derived geometries of the various contributing signals, also indicates that GMSL rose at a rate of 3.0 ± 0.7 millimetres per year between 1993 and 2010, consistent with prior estimates from tide gauge records.The increase in rate relative to the 1901-90 trend is accordingly larger than previously thought; this revision may affect some projections of future sea-level rise.

  11. Water supply for the Nuclear Rocket Development Station at the U.S. Atomic Energy Commission's Nevada Test Site

    USGS Publications Warehouse

    Young, Richard Arden

    1972-01-01

    The Nuclear Rocket Development Station, in Jackass Flats, occupies about 123 square miles in the southwestern part of the U.S. Atomic Energy Commission's Nevada Test Site. Jackass Flats, an intermontane valley bordered by highlands on all sides except for a drainage outlet in the southwestern corner, has an average annual rainfall of 4 inches. Jackass Flats is underlain by alluvium, colluvium, and volcanic rocks of Cenozoic age and, at greater depth, by sedimentary rocks of Paleozoic age. The alluvium and the colluvium lie above the saturated zone throughout nearly all of Jackass Flats. The Paleozoic sedimentary rocks contain limestone and dolomite units that are excellent water producers elsewhere ; however, these units are too deep in Jackass Flats to be economic sources of water. The only important water-producing unit known in the vicinity of the Nuclear Rocket Development Station is a welded-tuff aquifer, the Topopah Spring Member of the Paintbrush Tuff, which receives no significant recharge. This member contains about 500 feet of highly fractured rock underlying an area 11 miles long and 3 miles wide in western Jackass Flats. Permeability of the aquifer is derived mostly from joints and fractures; however, some permeability may be derived from gas bubbles in the upper part of the unit. Transmissivity, obtained from pumping tests, ranges from 68,000 to 488,000 gallons per day per foot. Volume of the saturated part of the aquifer is about 3.5 cubic miles, and the average specific yield probably ranges from 1 to 5 percent. The volume of ground water in storage is probably within the range of 37-187 billion gallons. This large amount of water should be sufficient to supply the needs of the Nuclear Rocket Development Station for many years. Water at the Nuclear Rocket Development Station is used for public supply, construction, test-cell coolant, exhaust cooling, and thermal shielding during nuclear reactor and engine testing, and washdown.

    Purpose: To present our method and experience in commissioning dose models in water for spot scanning proton therapy in a commercial treatment planning system (TPS). Methods: The input data required by the TPS included in-air transverse profiles and integral depth doses (IDDs). All input data were obtained from Monte Carlo (MC) simulations that had been validated by measurements. MC-generated IDDs were converted to units of Gy mm{sup 2}/MU using the measured IDDs at a depth of 2 cm employing the largest commercially available parallel-plate ionization chamber. The sensitive area of the chamber was insufficient to fully encompass the entire lateral dose deposited at depth by a pencil beam (spot). To correct for the detector size, correction factors as a function of proton energy were defined and determined using MC. The fluence of individual spots was initially modeled as a single Gaussian (SG) function and later as a double Gaussian (DG) function. The DG fluence model was introduced to account for the spot fluence due to contributions of large angle scattering from the devices within the scanning nozzle, especially from the spot profile monitor. To validate the DG fluence model, we compared calculations and measurements, including doses at the center of spread out Bragg peaks (SOBPs) as a function of nominal field size, range, and SOBP width, lateral dose profiles, and depth doses for different widths of SOBP. Dose models were validated extensively with patient treatment field-specific measurements. Results: We demonstrated that the DG fluence model is necessary for predicting the field size dependence of dose distributions. With this model, the calculated doses at the center of SOBPs as a function of nominal field size, range, and SOBP width, lateral dose profiles and depth doses for rectangular target volumes agreed well with respective measured values. With the DG fluence model for our scanning proton beam line, we successfully treated more than 500 patients

    This paper provides the official recommendation of the Union Internationale des Associations d'Alpinisme (UIAA) Medical Commission to manage the problem of safe drinking water. The recommendation was accepted and authorized for publication by the Medical Commission during their annual meeting at Treplice, Tzechia, 2008. Safe water is essential for mountaineers worldwide in order to balance challenges associated with high altitude dehydration. The paper summarizes the advantages and disadvantages of several procedures used to procure safe drinking water in the mountains or at high altitude. Limitations or critical details, which may cause failure of the methods are mentioned systematically. We differentiate between "conventional" methods, which should be preferred because they produce safe water and "improvisation". The latter does not produce safe water but may be used if conventional methods are not available for any reason. They decrease the concentration of pathogenic microorganisms and by this they reduce the risk of enteral infection. Water filtration using a ceramic filter system or chemical disinfection is recommended as a standard method. Boiling water should be avoided because it is too fuel consuming and has the potential to increase deforestation. Generally, with regard to infections by water or food, all mountaineers should be vaccinated against hepatitis A and poliomyelitis in regions where they may be at-risk. PMID:19174294

  5. Comparison of Standard Light Water Reactor Cross-Section Libraries using the United States Nuclear Regulatory Commission Boiling Water Reactor Benchmark Problem

    Kulesza, Joel A.; Arzu Alpan, F.

    2016-02-01

    This paper describes a comparison of contemporary and historical light water reactor shielding and pressure vessel dosimetry cross-section libraries for a boiling water reactor calculational benchmark problem. The calculational benchmark problem was developed at Brookhaven National Laboratory by the request of the U. S. Nuclear Regulatory Commission. The benchmark problem was originally evaluated by Brookhaven National Laboratory using the Oak Ridge National Laboratory discrete ordinates code DORT and the BUGLE-93 cross-section library. In this paper, the Westinghouse RAPTOR-M3G three-dimensional discrete ordinates code was used. A variety of cross-section libraries were used with RAPTOR-M3G including the BUGLE93, BUGLE-96, and BUGLE-B7 cross-section libraries developed at Oak Ridge National Laboratory and ALPAN-VII.0 developed at Westinghouse. In comparing the calculated fast reaction rates using the four aforementioned cross-section libraries in the pressure vessel capsule, for six dosimetry reaction rates, a maximum relative difference of 8% was observed. As such, it is concluded that the results calculated by RAPTOR-M3G are consistent with the benchmark and further that the different vintage BUGLE cross-section libraries investigated are largely self-consistent.

    This paper compares contemporary and historical light water reactor shielding and pressure vessel dosimetry cross-section libraries for a pressurized water reactor calculational benchmark problem with a standard out-in core loading. The calculational benchmark problem was developed at Brookhaven National Laboratory by the request of the U. S. Nuclear Regulatory Commission and used the Oak Ridge National Laboratory two-dimensional discrete ordinates code DORT and the BUGLE-93 cross-section library for the calculations. In this paper, a Westinghouse three-dimensional discrete ordinates code with parallel processing, the RAPTOR-M3G code was used. A variety of cross section libraries were used with RAPTOR-M3G including the BUGLE-93, BUGLE-96, and BUGLE-B7 cross-section libraries developed at Oak Ridge National Laboratory, and the broad-group ALPAN-VII.0 cross-section library developed at Westinghouse. In comparing the calculation-to-calculation reaction rates using the BUGLE-93 cross-section library at the thermal shield, pressure vessel, and cavity capsules, for eleven dosimetry reaction rates, a maximum relative difference of 5% was observed, with the exception of 65Cu(n,2n) in the pressure vessel capsule that had a 90% relative difference with respect to the reference results. It is thought that the 65Cu(n,2n) reaction rate reported in the reference for the pressure vessel capsule is not correct. In considering the libraries developed after BUGLE-93, a maximum relative difference of 12% was observed in reaction rates, with respect to the reference results, for 237Np(n,f) in the cavity capsule using BUGLE-B7.

    During their settlement of the so-called Old Italian Colonies of Rio Grande do Sul, immigrants constructed a set of positive values that were to serve as an emotional support and a means of outside communication. When women immigrants embroidered images and sayings on wall hangings or kitchen towels made of rustic fabric, they helped nourish the dream of a better life, sought by all and achieved by some. The objects crafted by these twentieth-century Penelopes bear witness to a way of doing, thinking, and acting. Local museums and exhibits have fostered the recovery of old-time embroidery techniques and themes; sold at open-air markets and regional festivals, these products represent income for women whose age excludes them from the formal labor market.

    1995-01-26

    PREFACE The Twentieth Workshop on Geothermal Reservoir Engineering, dedicated to the memory of Professor Hank Ramey, was held at Stanford University on January 24-26, 1995. There were ninety-five registered participants. Participants came from six foreign countries: Japan, Mexico, England, Italy, New Zealand and Iceland. The performance of many geothermal reservoirs outside the United States was described in several of the papers. Professor Roland N. Horne opened the meeting and welcomed visitors to the campus. The key note speaker was Marshall Reed, who gave a brief overview of the Department of Energy's current plan. Thirty-two papers were presented in the technical sessions of the workshop. Technical papers were organized into eleven sessions concerning: field development, modeling, well tesubore, injection, geoscience, geochemistry and field operations. Session chairmen were major contributors to the workshop, and we thank: Ben Barker, Bob Fournier, Mark Walters, John Counsil, Marcelo Lippmann, Keshav Goyal, Joel Renner and Mike Shook. In addition to the technical sessions, a panel discussion was held on ''What have we learned in 20 years?'' Panel speakers included Patrick Muffler, George Frye, Alfred Truesdell and John Pritchett. The subject was further discussed by Subir Sanyal, who gave the post-dinner speech at the banquet. The Workshop was organized by the Stanford Geothermal Program faculty, staff, and graduate students. We wish to thank our students who operated the audiovisual equipment. Shaun D. Fitzgerald Program Manager

  11. Redrawing the map: science in twentieth-century China.

    PubMed

    Fan, Fa-ti

    2007-09-01

    This essay argues that science in twentieth-century China is a rich topic that can be productively integrated into research and teaching on the history of modern science. It identifies major issues of science in twentieth-century China and demonstrates that they can prove useful to any scholar who wishes to consider science in a comparative and trans/international context. The essay suggests two important steps for a fruitful investigation into the topic of science in twentieth-century China: first, revising the historiographic assumptions and categories that underlie much of the conventional historical narrative of modern science; and, second, breaking free from the tunnel history of national science. To illustrate these points, the essay examines a series of case studies of science in modern China and discusses the relevance of such subjects as scientific nationalism, Maoist mass science, and transnational scientific networks for the understanding of science in the twentieth-century world.

  17. Turning points in twentieth-century American psychiatry.

    PubMed

    Sabshin, M

    1990-10-01

    The author examines four major turning points in twentieth-century American psychiatry, emphasizing the movement during the post-World War II period toward a psychotherapeutic/psychoanalytic approach and the emergence of biological psychiatry, neuroscience, and logical positivism during the 1970s and 1980s. He discusses the impact of Adolf Meyer during the mid-twentieth century and his ongoing influence. The final turning point involves a prediction of a late twentieth-century change, including new directions in nosology, emphasis on combined pharmacotherapeutic/psychotherapeutic treatments, efforts to create alternatives to full inpatient care, better outcome data for psychiatric treatments, and beginning resolution of major boundary problems of current practice.

  18. Hydrogeology of stratified-drift aquifers and water quality in the Nashua Regional Planning Commission Area, south-central New Hampshire

    USGS Publications Warehouse

    Toppin, K.W.

    1987-01-01

    The Nashua Regional Planning Commission area in south-central New Hampshire is a 12-community area that is experiencing increases in population and in demands for water supply. The study area is underlain by 129 sq mi (40% of the area) of stratified drift which, where sufficiently saturated and permeable, form the most productive aquifers in the area. Eight towns use the stratified-drift aquifers for municipal water supply. The saturated thickness of stratified drift in the study area ranges from 0 or < 20 ft near aquifer boundaries to more than 100 ft in the Souhegan and Merrimack River valleys. The transmissivity of stratified drift ranges from < 2,000 sq ft/day throughout much of the area to more than 8,000 sq ft/day in the communities of Amherst, Brookline, Hollis, Hudson, Litchfield, Merrimack, Milford, Nashua, and Pelham. Directions of groundwater flow are generally from valley walls to surface waters, which act as drains for the stratified drift aquifers. The estimated total yield of community water-supply systems in the study area (surface and groundwater combined) is 22 mgd (million gallons per day). Analytical modeling indicates that an additional 12 mgd could be obtained from six aquifers located in the communities of Amherst, Litchfield, Merrimack, Milford, and Pelham. Other aquifers in the area, not modeled in the study, could also provide increased amounts of water especially where yields could be augmented by induced recharge of surface water. Groundwater quality in the study area is characterized by naturally elevated levels of iron (Fe) and manganese (Mn). Of 32 wells sampled, 7 exceeded EPA recommended drinking water limits for both Fe and Mn, and 3 wells exceeded the Mn limit only. The average total dissolved solids concentration for 32 samples was 121 mg/L. Groundwater in the area is slightly corrosive; pH 's ranged from 5.0-7.3. Groundwater contamination has been detected at two ' Superfund ' sites in the study area located in Milford and

  8. The World Commission on Dams: A fundamental step towards integrated water resources management and poverty reduction? A pilot case in the Lower Zambezi, Mozambique

    NASA Astrophysics Data System (ADS)

    Scodanibbio, Lucia; Mañez, Gustavo

    The Cahora Bassa dam in the Lower Zambezi has undoubtedly brought varied economic benefits (such as hydroelectricity) to Mozambique. There is also, however, evidence of certain negative impacts that have increased the vulnerability of downstream populations. Specifically, current water management practices in the Zambezi have affected people’s livelihoods by the frequent unpredictable releases of water that wash away riverbank crops, impoverish fish stocks and fish habitat, and threaten the valuable shrimp exports. These releases have also worsened the effects of large floods, for example the floods of 2001. The ecosystem of the Zambezi delta, which is a Ramsar site, has also suffered since Cahora Bassa’s regulation. The Mozambican government is proposing to construct a new dam downstream of Cahora Bassa at Mphanda Nkuwa. In the feasibility study, there was no due consideration of rural downstream communities and their livelihoods. This has left many potentially affected people uninformed and vulnerable to the risks associated with the new development. The new dam is likely to worsen the already severe impacts of Cahora Bassa. The World Commission on Dams (WCD) developed seven strategic priorities, designed to inform all decisions related to future dam developments. These priorities follow principles of public participation, social equity, environmental sustainability, economic efficiency and accountability. The WCD proposed best-practice guidelines for both addressing existing dams and for any future ones which are planned. According to the WCD, affected communities have a right to participate in the decision to build a dam, they should be the first to benefit from the project, and the rivers on which their livelihoods are based should be protected. Stakeholder participation is one of the fundamental components of integrated water resources management (IWRM). For effective participation in dam projects, affected people need to be empowered, have access to

    The phenomenon of “missing women” has existed throughout the twentieth century in China. Using data from five censuses, with appropriate adjustments, we estimate the numbers and percentage of missing women from the period 1900–2000. The analysis is broken down into historically important periods, and the consequences of missing women, particularly that of China’s “bare branches” are explored. Implications for Chinese society are then discussed. PMID:24255550

  13. Mustaches and masculine codes in early twentieth-century America.

    PubMed

    Oldstone-Moore, Christopher

    2011-01-01

    The purpose of this article is to deepen our understanding of twentieth-century masculinity by considering the social function of facial hair. The management of facial hair has always been a medium of gendered body language, and as such has elicited a nearly continuous private and public conversation about manliness. Careful attention to this conversation, and to trends in facial hairstyles, illuminates a distinct and consistent pattern of thought about masculinity in early twentieth-century America. The preeminent form of facial hair - mustaches - was used to distinguish between two elemental masculine types: sociable and autonomous. A man was neither wholly one nor the other, but the presence and size of a mustache - or its absence - served to move a man one way or another along the continuum that stretched from one extreme to the other. According to the twentieth-century gender code, a clean-shaven man's virtue was his commitment to his male peers and to local, national or corporate institutions. The mustached man, by contrast, was much more his own man: a patriarch, authority figure or free agent who was able to play by his own rules. Men and women alike read these signals in their evaluation of men. PMID:22164885

  14. Guidelines for residential commissioning

    SciTech Connect

    Wray, Craig P.; Walker, Iain S.; Sherman, Max H.

    2003-01-31

    Currently, houses do not perform optimally or even as many codes and forecasts predict, largely because they are field assembled and there is no consistent process to identify problems or to correct them. Residential commissioning is a solution to this problem. This guide is the culmination of a 30-month project that began in September 1999. The ultimate objective of the project is to increase the number of houses that undergo commissioning, which will improve the quality, comfort, and safety of homes for California citizens. The project goal is to lay the groundwork for a residential commissioning industry in California focused on end-use energy and non-energy issues. As such, we intend this guide to be a beginning and not an end. Our intent is that the guide will lead to the programmatic integration of commissioning with other building industry processes, which in turn will provide more value to a single site visit for people such as home energy auditors and raters, home inspectors, and building performance contractors. Project work to support the development of this guide includes: a literature review and annotated bibliography, which facilitates access to 469 documents related to residential commissioning published over the past 20 years (Wray et al. 2000), an analysis of the potential benefits one can realistically expect from commissioning new and existing California houses (Matson et al. 2002), and an assessment of 107 diagnostic tools for evaluating residential commissioning metrics (Wray et al. 2002). In this guide, we describe the issues that non-experts should consider in developing a commissioning program to achieve the benefits we have identified. We do this by providing specific recommendations about: how to structure the commissioning process, which diagnostics to use, and how to use them to commission new and existing houses. Using examples, we also demonstrate the potential benefits of applying the recommended whole-house commissioning approach to

  18. Compulsory schooling reforms, education and mortality in twentieth century Europe.

    Education yields substantial non-monetary benefits, but the size of these gains is still debated. Previous studies report causal effects of education and compulsory schooling on mortality ranging anywhere from zero to large and negative. Using data from 18 compulsory schooling reforms implemented in Europe during the twentieth century, we quantify the average mortality gain and explore its dispersion across gender, time and countries. We find that more education yields small mortality reductions in the short- and long-run for men. In contrast, women seem to experience no mortality reductions from compulsory schooling reforms.

  12. Great Plains Drought in Simulations of Twentieth Century

    NASA Astrophysics Data System (ADS)

    McCrary, R. R.; Randall, D. A.

    2008-12-01

    The Great Plains region of the United States was influenced by a number of multi-year droughts during the twentieth century. Most notable were the "Dust Bowl" drought of the 1930s and the 1950s Great Plains drought. In this study we evaluate the ability of three of the Coupled Global Climate Models (CGCMs) used in the Fourth Assessment Report (AR4) of the IPCC to simulate Great Plains drought with the same frequency and intensity as was observed during the twentieth century. The models chosen for this study are: GFDL CM 2.0, NCAR CCSM3, and UKMO HadCM3. We find that the models accurately capture the climatology of the hydrologic cycle of the Great Plains, but that they tend to overestimate the variability in Great Plains precipitation. We also find that in each model simulation at least one long-term drought occurs over the Great Plains region during their representations 20th Century Climate. The multi-year droughts produced by the models exhibit similar magnitudes and spatial scales as was observed during the twentieth century. This study also investigates the relative roles that external forcing from the tropical Pacific and local feedbacks between the land surface and the atmosphere have in the initiation and perpetuation of Great Plains drought in each model. We find that cool, La Nina-like conditions in the tropical pacific are often associated with long-term drought conditions over the Great Plains in GFDL CM 2.0 and UKMO HadCM3, but there appears to be no systematic relationship between tropical Pacific SST variability and Great Plains drought in CCSM3. It is possible the strong coupling between the land surface and the atmosphere in the NCAR model causes precipitation anomalies to lock into phase over the Great Plains thereby perpetuating drought conditions. Results from this study are intended to help assess whether or not these climate models are credible for use in the assessment of future drought over the Great Plains region of the United States.

    Four US mobilizations in the twentieth century are compared in terms of several broad macroeconomic variables and assessed in terms of policy initiatives that preceded them. World War I was the least effective in delivering war material to US troops. World War 2, the only total'' mobilization, was highly effective, though it proceeded over a four or five-year period. The buildup of the Korean War, a more limited engagement, moved with relative speed. The Vietnam mobilization was essentially a minor increment to the prewar level of defense spending. Manpower sources in all four wars are also identified. Mobilization strategies have undergone frequent modification and were not always adequate to the mobilizations they served. 3 refs., 18 tabs.

  16. Climate of Hungary in the twentieth century according to Feddema

    Feddema's (Physical Geography 26:442-466, 2005) bioclimatic classification scheme is applied to Hungary for the twentieth century using the Climatic Research Unit (CRU) data series. The method is tested in two modes. In the first, its original form is used which is suitable for global scale analysis. In the second, the criteria used in the method are slightly modified for mesoscale classification purposes. In both versions, potential evapotranspiration (PET) is calculated using McKenney and Rosenberg's (Meteorol 64:81-110, 1993) formula. We showed that McKenney and Rosenberg's formula could be applied to Hungary. According to Feddema's global scale application, local climates of the three main geographical regions, the Great Hungarian Plain, the North Hungarian Mountains, and Transdanubia, can be distinguished. However, the spatial distribution pattern within the regions is poorly reproduced, if at all. According to Feddema's mesoscale application, a picture of climatic subregions could be observed.

    The abrupt Northern Hemispheric warming at the end of the twentieth century has been attributed to an enhanced greenhouse effect. Yet Greenland and surrounding subpolar North Atlantic remained anomalously cold in 1970s to early 1990s. Here we reconstructed robust Greenland temperature records (North Greenland Ice Core Project and Greenland Ice Sheet Project 2) over the past 2100 years using argon and nitrogen isotopes in air trapped within ice cores and show that this cold anomaly was part of a recursive pattern of antiphase Greenland temperature responses to solar variability with a possible multidecadal lag. We hypothesize that high solar activity during the modern solar maximum (approximately 1950s-1980s) resulted in a cooling over Greenland and surrounding subpolar North Atlantic through the slowdown of Atlantic Meridional Overturning Circulation with atmospheric feedback processes.

  18. Modeling and Reality in Early Twentieth-Century Physics

    Towards the end of 1913, Arnold Sommerfeld, Professor of theoretical physics at Munich University, sent a letter of congratulations to a young Niels Bohr. The Dane's now-classic trilogy of papers, which coupled Rutherford's conception of the atom with a ``planetary'' configuration of electrons, had just appeared. Sommerfeld saw the calculation of the Rydberg constant as a singular triumph and immediately spotted an opportunity to try to explain the Zeeman effect. Yet he also sounded a note of caution, confessing that he remained ``somewhat skeptical'' of atomic models in general. In this, of course, he was hardly alone. Bohr's atom was a particularly egregious example of a peculiar model, one requiring what even its creator considered ``horrid assumptions.'' Nonetheless, success bred conviction. Expanding upon Bohr's original ideas, Sommerfeld soon produced the so-called ``Bohr-Sommerfeld quantization conditions,'' using them to calculate a myriad of results. Experimental evidence, Sommerfeld argued in 1915, showed that quantised electron-paths ``correspond exactly to reality'' and possess ``real existence.'' This kind of realism would not, of course, last long. In 1925, Werner Heisenberg (earlier a student of Sommerfeld's) made scepticism about the details of the Bohr model into a methodological dictum, one later enshrined in the ``Copenhagen interpretation'' of quantum mechanics. This paper uses Sommerfeld's work from the turn of the twentieth century to the mid-1920s as a window onto a landscape involving multiple contestations over the legitimacy of atomic modelling. The surprise that greeted Heisenberg's and others' phenomenological insistences, we will see, can only be understood with reference to what should be considered a ``realist interlude'' in the history of twentieth century atomic physics, one inspired by the astonishing successes of Rutherford's and Bohr's imaginings.

    The Spallation Neutron Source accelerator complex consists of a 2.5 MeV H{sup -} front-end injector system, a 186 MeV normal-conducting linear accelerator, a 1 GeV superconducting linear accelerator, an accumulator ring, and associated beam transport lines. The linac was commissioned in five discrete runs, starting in 2002 and completed in 2005. The accumulator ring and associated beam transport lines were commissioned in two runs in January-February and April 2006. With the completed commissioning of the SNS accelerator, the facility has begun initial low-power operations. In the course of beam commissioning, most beam performance parameters and beam intensity goals have been achieved at low duty factor. A number of beam dynamics measurements have been performed, including emittance evolution, transverse coupling in the ring, beam instability thresholds, and beam distributions on the target. The commissioning results, achieved beam performance and initial operating experience of the SNS linac will be presented.

    Construction of the CEBAF accelerator, a 4 GeV CW recirculating linac, is virtually complete. The 338 power sources and superconducting RF cavities, which have all run above nominal operating gradient in vertical tests (average 10.7 MeV/m), are installed. All the major components of the nine recirculation arcs are installed and aligned. Pre-commissioning was performed in parallel with construction. Ninety-nine superconducting cavities were operated simultaneously at the nominal gradient of 5 MeV/m. A maximum beam current of 110 PA CW (ZOO PA design) was reached. A cryomodule with eight cavities has operated at 8 MeV/m. Commissioning of the entire machine began in May 94. Results obtained during commissioning of the two linacs and the first arc are presented. 600 MeV beam is ready to be brought to the first experimental hall meeting a DOE milestone established in 1988.

  2. Twentieth century ENSO-related precipitation mean states in twentieth century reanalysis, reconstructed precipitation and CMIP5 models

    El Niño-Southern Oscillation (ENSO)-related precipitation during the entire twentieth century is compared among the twentieth century reanalysis (20CR), a statistically reconstructed precipitation dataset (REC) and 30 Coupled Model Intercomparison Project Phase 5 (CMIP5) models. Empirical orthogonal functions, ENSO-related precipitation composites based on sea surface temperature (SST)-constructed ENSO index and singular value decomposition (SVD) are employed to extract ENSO-related precipitation/SST signals in each dataset. With the background trend being removed in all of the data, our results show that the REC and the 20CR resemble both in their precipitation climatology and ENSO-related precipitation results. The biases in the CMIP5 models precipitation climatology such as dry equator over the Pacific Ocean, "double-intertropical convergence zones (ITCZs)" and overly zonal Southern Pacific convergence zone (SPCZ) are major reasons for lowering spatial correlations with the REC and the 20CR precipitation climatology. Two groups of CMIP5 models are built based on severity of these biases in their precipitation background and the spatial correlations of ENSO-related precipitation with the observations. Compared with the group with more severe biases in its precipitation climatology, the group with smaller biases tends to produce more ENSO-like precipitation patterns, simulate more realistic mean magnitude and seasonal variability of ENSO precipitation signals, as well as generating better ENSO-related SST/precipitation correlation patterns produced in its SVD analysis. The ENSO-related precipitation biases in the CMIP5 models over the western Pacific and Indian Ocean, as well as the equatorial Pacific, are strongly related with their precipitation climatology biases over these regions. The ENSO-related precipitation biases over the off-equator eastern Pacific Ocean are associated with both the "double-ITCZs" biases in the precipitation climatology and the ENSO

  2. ADVANCES IN PLANT HEALTH MANAGEMENT IN THE TWENTIETH CENTURY.

    PubMed

    Cook, R. James

    2000-01-01

    Plant health management is the science and practice of understanding and overcoming the succession of biotic and abiotic factors that limit plants from achieving their full genetic potential as crops, ornamentals, timber trees, or other uses. Although practiced as long as agriculture itself, as a science-based concept, plant heath management is even younger than integrated pest management (IPM), and includes and builds upon but is not a replacement for IPM. Probably the greatest collection of success stories for plant health management is the number of diseases managed by cleaning up the planting material. The record for root health management is more mixed, with the loss or phase-out of soil fumigants, and practices such as crop rotation and clean tillage being replaced with more intensive cropping and less or no tillage. Perhaps the greatest scientific and technical advances for plant health management have come from the work aimed at management of the pathogens, pests, and other hazards that arrive by air. Flor's work on flax rust, which produced the gene-for-gene model, is possibly the most significant contribution of plant pathology to the life sciences in the twentieth century. Research aimed at the management of foliar pathogens is also the basis for modern theory on epidemiology, population biology, aerobiology, and disease prediction and decision-support systems. Even IPM arose mainly in response to the need to protect crops from pests that arrive by air. If the definition of biological control includes the plant induced or genetically modified to defend itself, as it should, then biological control has been the most significant approach to plant health management during the twentieth century and promises through modern biotechnology to be even more significant in the twenty-first century. Rather than "reducing losses," the advances are discussed here within the simple framework of achieving the attainable yield by increasing the actual and/or affordable

  3. Abrupt changes in rainfall during the twentieth century

    NASA Astrophysics Data System (ADS)

    Narisma, G.; Foley, J.; Licker, R.; Ramankutty, N.

    2007-12-01

    A sudden change in climate is brought about by complex interactions in the climate system, including interactions between land and atmosphere, that can give rise to strong positive feedback mechanisms. Paleoclimatic studies have shown that abrupt climate changes have happened in the geologic past. Studies of future climate change under global warming scenarios indicate the possibility of the sudden collapse of the thermohaline circulation, which will have major implications for the climate of Europe. However, abrupt climatic changes are not events of the geologic past or a computer-simulated future: they have occurred in recent history and have had serious consequences on society and the environment. The prolonged Sahel drought in the late 1960s and the Dust Bowl of the 1930s are examples of abrupt climatic changes of the twentieth century. Apart from these events, however, there has been no systematic survey of recent climate history to determine the prevalence of abrupt climatic changes. Given the potential cost of these abrupt changes, there is a need to investigate historical records for evidence of other sudden climatic changes in the more recent past. Here we analyze the Climate Research Unit global historical rainfall observations (covering the years 1901-2000) using wavelet analysis to detect regions that have undergone large, sudden decreases in rainfall. We show that in the twentieth century, aside from the Sahel and the US midwest, at least 30 regions in the world have experienced sudden climatic changes. These events are statistically significant at the 99 percent level, are persistent for at least ten years, and most have magnitudes of change that are 10 percent lower than the climatological normal (1901-2000 rainfall average). We also illustrate some of the potential consequences of these abrupt changes and show that these events had major impacts on social and environmental conditions. Interestingly, these regions of abrupt precipitation changes are

  4. On the Causes and Dynamics of the Early Twentieth Century North American Pluvial

    NASA Technical Reports Server (NTRS)

    Cook, Benjamin I.; Seager, Richard; Miller, Ron L.

    2011-01-01

    The early twentieth century North American pluvial (1905-1917) was one of the most extreme wet periods of the last five hundred years and directly led to overly generous water allotments in the water-limited American West. Here we examine the causes and dynamics of the pluvial event using a combination of observation-based data sets and general circulation model (GCM) experiments. The character of the moisture surpluses during the pluvial differed by region, alternately driven by increased precipitation (the Southwest), low evaporation from cool temperatures (the Central Plains), or a combination of the two (the Pacific Northwest). Cool temperature anomalies covered much of the west and persisted through most months, part of a globally extensive period of cooler land and sea surface temperatures (SST). Circulation during boreal winter favored increased moisture import and precipitation in the southwest, while other regions and seasons were characterized by near normal or reduced precipitation. Anomalies in the mean circulation, precipitation, and SST fields are partially consistent with the relatively weak El Nino forcing during the pluvial, and also reflect the impact of positive departures in the Arctic Oscillation that occurred in ten of the thirteen pluvial winters. Differences between the reanalysis dataset, an independent statistical drought model, and GCM simulations highlight some of the remaining uncertainties in understanding the full extent of SST forcing of North American hydroclimatic variability.

  5. Eye injuries in twentieth century warfare: a historical perspective.

    PubMed

    Wong, T Y; Seet, M B; Ang, C L

    1997-01-01

    With successive wars in the twentieth century, there has been a relative increase in injuries to the eye compared to injuries of other parts of the body. The main causes of eye injury have changed with advances in techniques and weaponry of warfare, with blast fragmentation injuries accounting for 50-80% of cases. Penetrating and perforating injuries are most common, and injuries associated with intraocular foreign bodies pose special diagnostic and management problems. Injuries are bilateral in 15-25% of cases. Injuries associated with chemical, nuclear, and laser weapons have distinct characteristics and epidemiology. Enucleation was commonly performed at the turn of the century, but incidence has declined with better understanding of the pathophysiology of ocular trauma, improved surgical techniques and sepsis control with antibiotics. Sympathetic ophthalmia appears to be uncommon and earlier fears of this complication seem to have been exaggerated. Timely evacuation to a surgical facility is important for a good visual prognosis and preservation of the globe. However, prevention of injuries with eye armor is ultimately the best management, and the need for a comprehensive eye protection program in the military cannot be overemphasized, especially since eye injuries pose important socioeconomic, as well as medical, problems.

  6. Tropospheric circulation during the early twentieth century Arctic warming

    2016-04-01

    The early twentieth century Arctic warming (ETCAW) between 1920-1940 is an exceptional feature of climate dynamics in the last century and its warming rate was only recently matched by anthropogenic global warming amplification in the Arctic region. However, atmospheric warming during the ETCAW was strongest in the mid-troposphere and is believed to be triggered by an exceptional case of natural climate variability. Nevertheless, ultimate mechanisms and causes for the ETCAW are still under discussion. Here we use state of the art multi member global circulation models, reanalysis and reconstruction datasets to investigate the internal atmospheric dynamics of the ETCAW. We use these gridded datasets to investigate the role of boreal winter mid-tropospheric heat transport and circulation in providing the energy for the large scale warming. Analysing heat flux components and regional differences, it was found that climate models are not able to reproduce the heat flux evolution shown by reanalysis and reconstruction datasets. These datasets compute an increase of stationary eddy heat flux and a decrease of transient eddy heat flux during the ETCAW. Moreover, tropospheric circulation analysis revealed the important role of both the Atlantic and the Pacific sectors in the convergence of southerly air masses into the Arctic during the warming event. Subsequently, it could be shown that the internal dynamics of the atmosphere played a major role in the formation in the ETCAW.

    The early twentieth century Arctic warming (ETCAW) between 1920 and 1940 is an exceptional feature of climate variability in the last century. Its warming rate was only recently matched by recent warming in the region. Unlike recent warming largely attributable to anthropogenic radiative forcing, atmospheric warming during the ETCAW was strongest in the mid-troposphere and is believed to be triggered by an exceptional case of natural climate variability. Nevertheless, ultimate mechanisms and causes for the ETCAW are still under discussion. Here we use state of the art multi-member global circulation models, reanalysis and reconstruction datasets to investigate the internal atmospheric dynamics of the ETCAW. We investigate the role of boreal winter mid-tropospheric heat transport and circulation in providing the energy for the large scale warming. Analyzing sensible heat flux components and regional differences, climate models are not able to reproduce the heat flux evolution found in reanalysis and reconstruction datasets. These datasets show an increase of stationary eddy heat flux and a decrease of transient eddy heat flux during the ETCAW. Moreover, tropospheric circulation analysis reveals the important role of both the Atlantic and the Pacific sectors in the convergence of southerly air masses into the Arctic during the warming event. Subsequently, it is suggested that the internal dynamics of the atmosphere played a major role in the formation in the ETCAW.

    The Majorana Demonstrator deploys high purity germanium (HPGe) detector modules to search for neutrinoless double beta (0 νββ) decay in 76Ge. The experiment is aimed at demonstrating the technical feasibility and low backgrounds for a next generation Ge-based BBz experiment. The program of testing and commissioning the Demonstrator modules is a critical step to debug and improve the experimental apparatus, to establish and refine operational procedures, and to develop data analysis tools. In this talk, we will discuss our experience commissioning the Demonstrator modules and show how this program leads to successful data-taking. This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Nuclear Physics, the Particle Astrophysics and Nuclear Physics Programs of the National Science Foundation, and the Sanford Underground Research Facility.

    1984-08-01

    IGSCC in BWR piping is occurring owing to a combination of material, environment, and stress factors, each of which can affect both the initiation of a stress-corrosion crack and the rate of its subsequent propagation. In evaluating long-term solutions to the problem, one needs to consider the effects of each of the proposed remedial actions. Mitigating actions to control IGSCC in BWR piping must be designed to alleviate one or more of the three synergistic factors: sensitized material, the convention BWR environment, and high tensile stresses. Because mitigating actions addressing each of these factors may not be fully effective under all anticipated operating conditions, mitigating actions should address two and preferably all three of the causative factors; e.g., material plus some control of water chemistry, or stress reversal plus controlled water chemistry.

    SciTech Connect

    Hart, E.O.

    1994-09-01

    This thesis discusses a recent United States Supreme Court case that will have a profound influence on the licensure of hydroelectric projects and the related ability of States to protect the quality of their waters. On October 4, 1993, the Supreme Court granted a Writ of Certiorari to resolve a conflict among the state courts of last resort. This case involves two fundamental and competing national interests: the nation's thirst for cheap, dependable power versus its equally strong desire to improve the quality of its water resources. It also involves two underlying regulatory regimes that overlap and conflict with each other in some ways. This case illustrates how those two national interests and their underlying regulatory regimes cannot always be reconciled. It also demonstrates how Congress, with its muddled ways of passing legislation, can create conflicts between federal and state regulatory agencies.

    Commissioning is the process of verifying that a building's heating, ventilation, and air conditioning (HVAC) and lighting systems perform correctly and efficiently. Without commissioning, system and equipment problems can result in higher than necessary utility bills and unexpected and costly equipment repairs. This report reviews the benefits of commissioning, why it is a requirement for Leadership in Energy and Environmental Design (LEED) certification, and why building codes are gradually adopting commissioning activities into code.

  17. Developing a Climatology of Atmospheric Rivers Impacting Greenland Using the Twentieth Century Reanalysis

    Neff, W. D.; Compo, G. P.

    2014-12-01

    A recent paper [Neff et al., 2014]examined the factors underlying the 2012 melt episode that covered the Greenland ice sheet and compared it with the same factors identified for the last episode in 1889, using the Twentieth Century Reanalysis (20CR: [Compo et al., 2011]). A key factor was the presence of an Atmospheric River (AR) that transported warm air from a mid-continent heat wave over the Atlantic Ocean and thence to the west coast of Greenland and then over the ice sheet. The 20CR proved quite effective in defining the structure and transport paths for both events. Although these events with wide spread melting of the ice sheet surface are extremely rare, a question remains as to the frequency of AR events and the ancillary conditions required for extensive melting of the ice sheet. Although the 20CR was effective in capturing the structure of AR events in 1889, an analysis of the northward transport of moisture off the west coast of Greenland at 850 hPa shows weaker transport prior to 1921 than after. In this study, we use time series of meridional velocity and specific humidity at 850 hPa during boreal summer months as a screening tool for high transport events. We attribute the muted representation of synoptic features to be an artifact of of sparse available stations reporting pressure along the northeast coast of Canada prior to 1921. For this reason we use different thresholds before and after 1921 to identify potential AR events. For each potential event we then examine maps of integrated water vapor between 240oW to 340oW and 20oN to 80oN to identify those with the IWV pattern characteristic of an AR. In our earlier study, we used the only station, Ilulissat, recording daily data on the west coast of Greenland corresponding to the entire1871-2012 period of the 20CR for verification of events in 1889 and 2012. In that analysis, temperatures maximized prior to each event together with light precipitation on the coast. In this study, we have used this

    The Climate System Model, a coupled global climate model without `flux adjustments' recently developed at the National Center for Atmospheric Research, was used to simulate the twentieth-century climate using historical greenhouse gas and sulfate aerosol forcing. This simulation was extended through the twenty-first century under two newly developed scenarios, a business-as-usual case (ACACIA-BAU, CO2 710 ppmv in 2100) and a CO2 stabilization case (STA550, CO2 540 ppmv in 2100). Here we compare the simulated and observed twentieth-century climate, and then describe the simulated climates for the twenty-first century. The model simulates the spatial and temporal variations of the twentieth-century climate reasonably well. These include the rapid rise in global and zonal mean surface temperatures since the late 1970s, the precipitation increases over northern mid- and high-latitude land areas, ENSO-induced precipitation anomalies, and Pole-midlatitude oscillations (such as the North Atlantic oscillation) in sea level pressure fields. The model has a cold bias (2°-6°C) in surface air temperature over land, overestimates of cloudiness (by 10%-30%) over land, and underestimates of marine stratus clouds to the west of North and South America and Africa.The projected global surface warming from the 1990s to the 2090s is 1.9°C under the BAU scenario and 1.5°C under the STA550 scenario. In both cases, the midstratosphere cools due to the increase in CO2, whereas the lower stratosphere warms in response to recovery of the ozone layer. As in other coupled models, the surface warming is largest at winter high latitudes (5.0°C from the 1990s to the 2090s) and smallest (1.0°C) over the southern oceans, and is larger over land areas than ocean areas. Globally averaged precipitation increases by 3.5% (3.0%) from the 1990s to the 2090s in the BAU (STA550) case. In the BAU case, large precipitation increases (up to 50%) occur over northern mid- and high latitudes and over

    Multistate regional commissions in the United States have been used since 1965. The largest program has been that of the Appalachian Regional Commission (ARC). Institutional and financial barriers have been the most difficult problems encountered by the ARC and other programs (such as Title V commissions). Despite the imperfect performance of the existing regional commissions, they offer a demonstration that some improvement in governmental performance can be achieved. There is virtual unanimity among the nation's governors that this is the route for Federal state relations to follow. Also, the commission route is viewed privately as the most socially acceptable means to have a beneficial impact on government performance. (SAC)

    Commission 10 of the International Astronomical Union has more than 650 members who study a wide range of activity phenomena produced by our nearest star, the Sun. Solar activity is intrinsically related to solar magnetic fields and encompasses events from the smallest energy releases (nano- or even picoflares) to the largest eruptions in the Solar System, coronal mass ejections (CMEs), which propagate into the Heliosphere reaching the Earth and beyond. Solar activity is manifested in the appearance of sunspot groups or active regions, which are the principal sources of activity phenomena from the emergence of their magnetic flux through their dispersion and decay. The period 2008-2009 saw an unanticipated extended solar cycle minimum and unprecedentedly weak polar-cap and heliospheric field. Associated with that was the 2009 historical maximum in galactic cosmic rays flux since measurements begun in the middle of the 20th Century. Since then Cycle 24 has re-started solar activity producing some spectacular eruptions observed with a fleet of spacecraft and ground-based facilities. In the last triennium major advances in our knowledge and understanding of solar activity were due to continuing success of space missions as SOHO, Hinode, RHESSI and the twin STEREO spacecraft, further enriched by the breathtaking images of the solar atmosphere produced by the Solar Dynamic Observatory (SDO) launched on 11 February 2010 in the framework of NASA's Living with a Star program. In August 2012, at the time of the IAU General Assembly in Beijing when the mandate of this Commission ends, we will be in the unique position to have for the first time a full 3-D view of the Sun and solar activity phenomena provided by the twin STEREO missions about 120 degrees behind and ahead of Earth and other spacecraft around the Earth and ground-based observatories. These new observational insights are continuously posing new questions, inspiring and advancing theoretical analysis and

    Commission 10 deals with solar activity in all of its forms, ranging from the smallest nanoflares to the largest coronal mass ejections. This report reviews scientific progress over the roughly two-year period ending in the middle of 2008. This has been an exciting time in solar physics, highlighted by the launches of the Hinode and STEREO missions late in 2006. The report is reasonably comprehensive, though it is far from exhaustive. Limited space prevents the inclusion of many significant results. The report is divided into the following sections: Photosphere and chromosphere; Transition region; Corona and coronal heating; Coronal jets; flares; Coronal mass ejection initiation; Global coronal waves and shocks; Coronal dimming; The link between low coronal CME signatures and magnetic clouds; Coronal mass ejections in the heliosphere; and Coronal mass ejections and space weather.

  12. SSCL Commissioning and Operations

    SciTech Connect

    1992-03-31

    The SSC, with an energy of 20 TeV/Beam, requires a sequence of individual accelerators of increasing energy in the injector chain. These are the Linac, Low Energy Booster, Medium Energy Booster, and High Energy Booster. Each accelerator system must be completed in sequence in order to provide beam to the next higher energy accelerator. The collider itself is comprised of ten sectors, each of which in terms of superconducting magnet bending strength, is equivalent to two HEB injectors. The completion of all injectors and collider sectors is required before stored beams can circulate in preparation for colliding beam operation. Four experimental halls are planned for the detector systems. Each major detector will be assembled in one of the halls by a world-wide collaboration of scientists. In addition, above ground facilities provide shops and test facilities for accelerator technical systems, superconducting magnet and materials research and development, and for detector assembly and operations. The purpose of this report is to present a plan for the sequential commissioning and operation of these individual accelerators and other technical facilities of the SSC. A central objective of this plan is to describe the activities at the SSCL that are not included as part of the construction project TPC, even though they occur during the overall project construction time-frame. Examples of such activities include the operation of general laboratory facilities and services not specifically related to construction, the operating costs for the individual accelerators in the injector chain once these facilities have been commissioned, and the costs of SSCL physics research groups. The Department of Energy has provided the following decision with regard to these operations categories for the SSCL.

    British by birth Allan Cyril Brooks (1869-1946) emigrated to Canada in the 1880s, and became one of the most important North American bird illustrators during the first half of the twentieth century. Brooks was one of the leading ornithologists and wildlife collectors of the time; he corresponded extensively with other ornithologists and supplied specimens to many major North American museums. From the 1890s on he hoped to support himself by painting birds and mammals, but this was not possible in Canada at that time and he was forced to turn to American sources for illustration commissions. His work can be compared with that of his contemporary, the leading American bird painter Louis Agassiz Fuertes (1874-1927), and there are striking similarities and differences in their careers. This paper discusses the work of a talented, self-taught wildlife artist working in a North American milieu, his difficulties and successes in a newly developing field, and his quest for Canadian recognition.

The laboratory being constructed is a showcase of modern design methods being built at a construction cost of less than $180 per sq. ft. This is possible in part because of the total commissioning activities that are being utilized for this project. The laboratory's unique approach to commissioning will be presented in this paper. The process will be followed through from the conceptual stage on into the actual construction portion of the laboratory. Lessons learned and cost effectiveness will be presented in a manner that will be usable for others making commissioning related decisions. Commissioning activities at every stage of the design will be presented along with the attributed benefits. Attendees will hear answers to the what, when, who, and why questions associated with commissioning of this exciting project.

    A simple and rapid method able to determine residues of seven quinolone antibacterials in whole eggs is presented here. This method is based on the matrix solid-phase dispersion technique with hot water as extractant followed by liquid chromatography-tandem mass spectrometry. After depositing 1.5 g of an egg sample containing the analytes and the analyte surrogate (norfloxacin) on sand (crystobalite), this material was packed into an extraction cell. Quinolones were extracted by flowing 6 mL of water acidified with 50 mmol/L formic acid through the cell heated at 100 degrees C. After pH adjustment and filtration of the extract, 100 microL of it was injected into the LC column. MS data acquisition was performed in the multiple reaction monitoring mode, selecting two precursor ion to product ion transitions for each target compound. Hot water appeared an efficient extracting medium, since absolute recoveries of the analyte in egg at the level of 20 ng/g were 89-103%. Estimated limits of quantification (S/N=10) were 0.2-0.6 ng/g. Based on the EU Commission Decision 2002/657/EC, the method was validated in terms of ruggedness, specificity, linearity, within-laboratory reproducibility, decision limit (CCalpha and detection capability (CCbeta). Depending on the particular analyte, CCalphas ranged between 0.41 and 2.6 ng/g, while CCbetas were 0.64-3.7 ng/g. The method was linear in the 3-30 ng/g range, with typical R(2) values higher than 0.97. The within-laboratory reproducibility (n=21) at 6 ng/g level was in the 9.0-12% range. After validation, a depletion study of enrofloxacin and one of its metabolites, i.e. ciprofloxacin, in eggs was conducted.

  20. Liberalism, authority, and bioethics commissions.

    PubMed

    MacDougall, D Robert

    2013-12-01

    Bioethicists working on national ethics commissions frequently think of themselves as advisors to the government, but distance themselves from any claims to actual authority. Governments however may find it beneficial to appear to defer to the authority of these commissions when designing laws and policies, and might appoint such commissions for exactly this reason. Where does the authority for setting laws and policies come from? This question is best answered from within a normative political philosophy. This paper explains the locus of moral authority as understood within one family of normative political theories--liberal political theories--and argues that most major "liberal" commentators have understood both the source and scope of ethics commissions' authority in a manner at odds with liberalism, rightly interpreted. The author argues that reexamining the implications of liberalism for bioethics commissions would mean changing what are considered valid criticisms of such commissions and also changing the content of national bioethics commission mandates. The author concludes that bioethicists who participate in such commissions ought to carefully examine their own views about the normative limits of governmental authority because such limits have important implications for the contribution that bioethicists can legitimately make to government commissions.

  1. Suitability of the Twentieth Century Reanalysis for climate change assessment

    Ferguson, Craig R.; Villarini, Gabriele

    2013-04-01

    The ever-growing demand for applications in climate science, and particularly in the realm of climate change attribution has triggered a paradigm shift in reanalysis production towards so-called "climate-quality" reanalyses. Climate-quality reanalyses seek to ameliorate the issue of unphysical time-varying biases through the assimilation of only those few data streams that are stable over long periods of time. The first attempt at such a reanalysis is the National Oceanic and Atmospheric Administration (NOAA) - Cooperative Institute for Research in Environmental Sciences (CIRES) Twentieth Century Reanalysis (20CR), which spans a period of 140-years (1871-2010)- more than doubling the pre-existing reanalysis record length. The 20R assimilates only synoptic surface and sea level pressure observations and uses monthly sea surface temperature and sea ice extent observations as boundary forcing. If its record can be shown to be homogenous, then it constitutes the first reanalysis suitable for long-term trend assessments. On the other hand, if discontinuities exist, then their presence will confound the detection and attribution of a possible climate change signal, making accounting for them a critical step in improving the applicability of these products in climate research. In previous work, we applied three statistical breakpoint methods (Pettitt and Bai-Perron tests and segmented regression) to evaluate the homogeneity of nine hydrometeorological variables in 20CR over the central U.S. We were able to show, through joint analyses of 20CR's ensemble spread and assimilated observation counts and inter-comparison with independent gridded datasets, that the quintupling of 20CR's assimilated observation counts was the primary cause of inhomogeneities for that region. In this study, we extend the same analysis methodology globally. We rigorously evaluate series homogeneity at regional, seasonal, inter-variable, and intra-ensemble scales. We analyze the metadata

    ALICE is a dedicated heavy-ion experiment at CERN LHC aiming to study the properties of the quark-gluon plasma. A lead-lead collision might produce several 10 00 new particles. Detailed study of the event requires precise measurements of the particle tracks. A 90 m3 Time Projection Chamber (TPC) with more than 500 000 read-out pads was built as the main central barrel tracker. Collisions can be recorded at a rate of up to about 1 kHz. The front-end electronics, designed from FPGAs and custom ASICs, performs shaping, amplification, digitisation and digital filtering of the signals. The data are forwarded to DAQ via 216 1.25 Gb/s fibre-optical links. Configuration, control and monitoring is done by an embedded Linux system on the front-end electronics. Before production runs with beam, extensive commissioning using tracks from cosmics and from the laser system as well as clusters from radioactive krypton gas is needed. Extensive results have been obtained with respect to the performance of the TPC including its sub-systems.

  4. Ozone transport commission developments

    Joyce, K.M.

    1995-08-01

    On September 27, 1994, the states of the Ozone Transport Commission (OTC) signed an important memorandum of understanding (MOU) agreeing to develop a regional strategy for controlling stationary sources of nitrogen oxide emissions. Specifically, the states of the Ozone Transport Region, OTR, agreed to propose regulations for the control of NOx emissions from boilers and other indirect heat exchangers with a maximum gross heat input rate of at least 250 million BTU per hour. The Ozone Transport Region was divided into Inner, Outer and Northern Zones. States in the Outer Zone agreed to reduce NOx emissions by 55%. States in the Inner Zone agreed to reduce NOx emissions 65%. Facilities in both zones have the option to emit NOx at a rate no greater than 0.2 pounds per million Btu by May 1, 1999. This option provides fairness for the gas-fired plants which already have relatively low NOx emissions. Additionally, States in the Inner and Outer Zones agreed to reduce their NOx emissions by 75% or to emit NOx at a rate no greater than 0.15 pounds per million BTU by May 1, 2003. The Northern Zone States agree to reduce their rate of NOx emissions by 55% from base year levels by May 1, 2003, or to emit NOx at a rate no greater than 0.2 pounds per million BTU. As part of this MOU, States also agreed to develop a regionwide trading mechanism to provide a cost-effective mechanism for implementing the reductions.

  5. A twentieth-century reanalysis forced ocean model to reconstruct the North Atlantic climate variation during the 1920s

    The observed North Atlantic multi-decadal variability for the period 1872-2009 is reconstructed with the Max Planck Institute ocean model, which is forced with an ensemble of the atmospheric twentieth century reanalysis. Special emphasis is put on the early part of the experiments, which includes a prominent climate variation during the 1920s. The experiments are in agreement with selected hydrographic records, indicating a transition from cold and fresh North Atlantic water properties, prior to the 1920 climate variation, towards warm and saline waters afterwards. Examining the variation reveals that sea level pressure (SLP) anomalies prior to the 1900s resemble a negative phase of North Atlantic Oscillation and associated weak winds result in a weak North Atlantic Current (NAC) and sub-polar gyre (SPG). This leads to a reduced transport of warm and saline waters into the higher latitudes. Simultaneously, Arctic freshwater release results in the accumulation of cold and fresh water properties, which cover the upper layers in the Labrador Sea and subsequently suppress convection. From the 1910s, the Arctic freshwater export is reduced, and, NAC and SPG are strengthened as a result of an increased SLP gradient over the North Atlantic. Concurrently, Labrador Sea convection and Atlantic meridional overturning circulation (AMOC) increase. The intensified NAC, SPG, and AMOC redistribute sub-tropical water into the North Atlantic and Nordic Seas, thereby increasing observed and modelled temperature and salinity during the 1920s.

  7. Industrial Characteristics and Employment of Older Manufacturing Workers in the Early-Twentieth-Century United States

    PubMed Central

    Lee, Chulhee

    2015-01-01

    This study explores how industry-specific technological, organizational, and managerial features affected the employment of old male manufacturing workers in the early twentieth-century United States. Industrial characteristics favorably related to the employment of old industrial workers include high labor productivity, less capital- and material-intensive production, short workdays, low intensity of work, high job flexibility, and formalized employment relationship. Results show that aged industrial workers were heavily concentrated in “unfavorable” industries, suggesting that the contemporary argument of “industrial scrap heap” was applicable for most of the manufacturing workers in the early twentieth century United States.

    2007-03-01

    The most intensely discussed and controversial issue in time keeping has been the proposal before the International Telecommunications Union (ITU) to redefine Coordinated Universal Time (UTC) so as to replace leap seconds by leap hours. Should this proposal be adopted, the practice of inserting leap seconds would cease after a specific date. Should the Earth's rotation continue to de-accelerate at its historical rate, the next discontinuity in UTC would be an hour inserted several centuries from now. Advocates of this proposal cite the need to synchronize satellite and other systems, such as GPS, Galileo, and GLONASS, which did not exist and were not envisioned when the current system was adopted. They note that leap second insertions can be and have been incorrectly implemented or accounted for. Such errors have to date had localized impact, but they could cause serious mishaps involving loss of life. For example, some GPS receivers have been known to fail simply because there was no leap second after a long enough interval, other GPS receivers failed because the leap second information was broadcast more than three months in advance, and some commercial software used for internet time-transfer Network Time Protocol (NTP) could either discard all data received after a leap second or interpret it as a frequency change. The ambiguity associated with the extra second could also disrupt financial accounting and certain forms of encryption. Those opposed to the proposal question the need for a change, and also point out the costs of adjusting to the proposed change and its inconvenience to amateur astronomers and others who rely upon astronomical calculations published in advance. Reports have been circulated that the cost of checking and correcting software to accommodate the new definition of UTC would be many millions of dollars for some systems. In October 2005 American Astronomical Society asked the ITU for a year's time to study the issue. This commission has

  15. Climate science: Water's past revisited to predict its future

    NASA Astrophysics Data System (ADS)

    Kirby, Matthew E.

    2016-04-01

    A reconstruction of 1,200 years of water's history in the Northern Hemisphere, based on proxy data, fuels the debate about whether anthropogenic climate change affected twentieth-century precipitation. See Letter p.94

  16. New perspectives on forced migration in the history of twentieth-century neuroscience.

    PubMed

    Stahnisch, Frank W; Russell, Gül

    2016-01-01

    This special issue of the Journal of the History of the Neurosciences, comprised of six articles and one commentary, reflects on the multifold dimensions of intellectual migration in the neurosciences and illustrates them by relevant case studies, biographies, and surveys from twentieth-century history of science and medicine perspectives. The special issue as a whole strives to emphasize the impact of forced migration in the neurosciences and psychiatry from an interdisciplinary perspective by, first, describing the general research topic, second, by showing how new models can be applied to the historiography and social studies of twentieth-century neuroscience, and, third, by providing a deeper understanding of the impact of European émigré researchers on emerging allied fields, such as neurogenetics, biological psychiatry, psychosomatics, and public mental health, etc. as resulting from this process at large.

  17. The biological universe: the twentieth-century extraterrestrial life debate and the limits of science

    NASA Astrophysics Data System (ADS)

    Dick, Steven J.

    Throughout the twentieth century, from the furor over Percival Lowell's claim of canals on Mars to the sophisticated Search for Extraterrestrial Intelligence, otherworldly life has often intrigued and occasionally consumed science and the public. Does `biological law' reign throughout the universe? Are there other histories, religions, and philosophies outside of those on Earth? Do extraterrestrial minds ponder the mysteries of the universe? The attempts toanswer these often asked questions form one of the most interesting chapters in the history of science and culture, and The Biological Universe is the first book to provide a rich and colorful history of those attempts during the twentieth century. Covering a broad range of topics, including the search for life in the solar system, the origins of life, UFOs, and aliens in science fiction, Steven J. Dick shows how the concept of extraterrestrial intelligence is a world view of its own, a `biophysical cosmology' that seeks confirmation no less than physical views of the universe.

  19. Rabid epidemiologies: the emergence and resurgence of rabies in twentieth century South Africa.

    PubMed

    Brown, Karen

    2011-01-01

    This article discusses the history of rabies in South Africa since the early twentieth century. It argues that rabies is a zoonotic disease that traverses rural and urban spaces, that transfers itself between wild and domestic animals and remains a potential threat to human life in the region. Scientists discovered an indigenous form of rabies, found primarily in the yellow mongoose, after the first biomedically confirmed human fatalities in 1928. Since the 1950s canine rabies, presumed to have moved southwards from across the Zambezi River, has become endemic also. South Africa is home to a comparatively large number of rabies strains and animal carriers, making it a particularly interesting case study. Environmental changes during the colonial and apartheid periods have helped to explain the increase in rabies cases since the mid-twentieth century. Moreover, developments in the biological and ecological sciences have provided insights into why the rabies virus has become endemic in certain wildlife species.

  20. Oral history, subjectivity, and environmental reality: Occupational health histories in twentieth-century Scotland

    SciTech Connect

    Johnston, R.; McIvor, A.

    2004-07-01

    This essay uses oral histories of dust disease in twentieth-century Scotland to illustrate the ways in which such history can illuminate how the working environment and work cultures affect workers' bodies and how workers come to terms with the ill-health caused by their employment. It emphasizes the agency of the interpreter but argues further that oral histories of dust disease in twentieth-century Scotland are simultaneously influenced by, and evidence for, material conditions. The essay explores the notion that the bodies, not just the voices of interviewees, are material testament to health-corroding work practices, cultures, and habitat. The focus is the problems caused by the inhalation of coal and asbestos dust.

  1. The holist tradition in twentieth century genetics. Wilhelm Johannsen's genotype concept.

    PubMed

    Roll-Hansen, Nils

    2014-06-01

    The terms 'genotype', 'phenotype' and 'gene' originally had a different meaning from that in the Modern Synthesis. These terms were coined in the first decade of the twentieth century by the Danish plant physiologist Wilhelm Johannsen. His bean selection experiment and his theoretical analysis of the difference between genotype and phenotype were important inputs to the formation of genetics as a well-defined special discipline. This paper shows how Johannsen's holistic genotype theory provided a platform for criticism of narrowly genocentric versions of the chromosome theory of heredity that came to dominate genetics in the middle decades of the twentieth century. Johannsen came to recognize the epoch-making importance of the work done by the Drosophila group, but he continued to insist on the incompleteness of the chromosome theory. Genes of the kind that they mapped on the chromosomes could only give a partial explanation of biological heredity and evolution. PMID:24882823

  2. Timing effects on first marriage: twentieth-century experience in England and Wales and the USA.

    PubMed

    Schoen, Robert; Canudas-Romo, Vladimir

    2005-07-01

    Recent substantial declines in first marriage in Western countries have been accompanied by increases in the average age at first marriage. Since the period proportion ever marrying, PEM, is sensitive to cohort tempo changes, the recent fall in the PEM may simply reflect cohort delays in marriage. The importance of timing factors is examined in the light of twentieth-century experience of first marriage in England and Wales and the USA. Using a variant of the Timing Index developed in research on fertility, we measure cohort timing effects for marriage and calculate an adjusted PEM. After examining twentieth-century trends in nuptiality for men and women, we find substantial tempo effects on the period PEM. Adjusted PEM values show a real decline in marriage for cohorts, but that decline is considerably smaller than the one shown by the unadjusted figures. This is especially true for England and Wales, where the decline in marriage was much greater.

  4. How to manage a revolution: Isaac Newton in the early twentieth century

    PubMed Central

    Clarke, Imogen

    2014-01-01

    In the first half of the twentieth century, dramatic developments in physics came to be viewed as revolutionary, apparently requiring a complete overthrow of previous theories. British physicists were keen to promote quantum physics and relativity theory as exciting and new, but the rhetoric of revolution threatened science's claim to stability and its prestigious connections with Isaac Newton. This was particularly problematic in the first decades of the twentieth century, within the broader context of political turmoil, world war, and the emergence of modernist art and literature. This article examines how physicists responded to their cultural and political environment and worked to maintain disciplinary connections with Isaac Newton, emphasizing the importance of both the old and the new. In doing so they attempted to make the physics ‘revolution’ more palatable to a British public seeking a sense of permanence in a rapidly changing world.

  5. A historical synopsis of farm animal disease and public policy in twentieth century Britain

    PubMed Central

    Woods, Abigail

    2011-01-01

    The diseases suffered by British livestock, and the ways in which they were perceived and managed by farmers, vets and the state, changed considerably over the course of the twentieth century. This paper documents and analyses these changes in relation to the development of public policy. It reveals that scientific knowledge and disease demographics cannot by themselves explain the shifting boundaries of state responsibility for animal health, the diseases targeted and the preferred modes of intervention. Policies were shaped also by concerns over food security and the public's health, the state of the national and livestock economy, the interests and expertise of the veterinary profession, and prevailing agricultural policy. This paper demonstrates how, by precipitating changes to farming and trading practices, public policy could sometimes actually undermine farm animal health. Animal disease can therefore be viewed both as a stimulus to, and a consequence of, twentieth century public policy. PMID:21624915

  7. On the rate and causes of twentieth century sea-level rise.

    PubMed

    Miller, Laury; Douglas, Bruce C

    2006-04-15

    Both the rate and causes of twentieth century global sea-level rise (GSLR) have been controversial. Estimates from tide-gauges range from less than one, to more than two millimetre yr(-1). In contrast, values based on the processes mostly responsible for GSLR-mass increase (from mountain glaciers and the great high latitude ice masses) and volume increase (expansion due to ocean warming)-fall below this range. Either the gauge estimates are too high, or one (or both) of the component estimates is too low. Gauge estimates of GSLR have been in dispute for several decades because of vertical land movements, especially due to glacial isostatic adjustment (GIA). More recently, the possibility has been raised that coastal tide-gauges measure exaggerated rates of sea-level rise because of localized ocean warming. Presented here are two approaches to a resolution of these problems. The first is morphological, based on the limiting values of observed trends of twentieth century relative sea-level rise as a function of distance from the centres of the ice loads at last glacial maximum. This observational approach, which does not depend on a geophysical model of GIA, supports values of GSLR near 2 mm yr(-1). The second approach involves an analysis of long records of tide-gauge and hydrographic (in situ temperature and salinity) observations in the Pacific and Atlantic Oceans. It was found that sea-level trends from tide-gauges, which reflect both mass and volume change, are 2-3 times higher than rates based on hydrographic data which reveal only volume change. These results support those studies that put the twentieth century rate near 2 mm yr(-1), thereby indicating that mass increase plays a much larger role than ocean warming in twentieth century GSLR.

  8. Law sets up oceans commission

    In an anticipated move, U.S. President Bill Clinton on August 7 signed into law the Oceans Act of 2000.The bipartisan legislation, which takes effect on January 20,2001, establishes a commission on ocean policy to examine federal ocean policy and environmental and economic trends affecting oceans and coasts.The act—which grew out of a call issued by Clinton at the National Oceans Conference in Monterey, California in 1998—requires the commission to submit recommendations to Congress and the president within 18 months of its appointment, and for the President to submit proposals to Congress about the use and stewardship of ocean and coastal resources.

    Commission 8 has regularly published triennial reports in the past and the current OC therefore voted to adopt a traditional format also for this special Legacy issue of the IAU Transactions. The outgoing President is grateful for the support of many Commission members who contributed to this report. Our contribution consists of 3 parts: 1) this introduction, providing a general overview and highlights of recent research in astrometry, 2) a summary of the astrometry business & science meeting at the 2015 IAU General Assembly, and 3) the activity report of our Commisson covering the mid-2012 to mid-2015 period.

  10. Mass and volume contributions to twentieth-century global sea level rise.

    PubMed

    Miller, Laury; Douglas, Bruce C

    2004-03-25

    The rate of twentieth-century global sea level rise and its causes are the subjects of intense controversy. Most direct estimates from tide gauges give 1.5-2.0 mm yr(-1), whereas indirect estimates based on the two processes responsible for global sea level rise, namely mass and volume change, fall far below this range. Estimates of the volume increase due to ocean warming give a rate of about 0.5 mm yr(-1) (ref. 8) and the rate due to mass increase, primarily from the melting of continental ice, is thought to be even smaller. Therefore, either the tide gauge estimates are too high, as has been suggested recently, or one (or both) of the mass and volume estimates is too low. Here we present an analysis of sea level measurements at tide gauges combined with observations of temperature and salinity in the Pacific and Atlantic oceans close to the gauges. We find that gauge-determined rates of sea level rise, which encompass both mass and volume changes, are two to three times higher than the rates due to volume change derived from temperature and salinity data. Our analysis supports earlier studies that put the twentieth-century rate in the 1.5-2.0 mm yr(-1) range, but more importantly it suggests that mass increase plays a larger role than ocean warming in twentieth-century global sea level rise.

    2013-09-01

    Hugo de Vries's mutation theory is now little more than a footnote to the history of biology, a failed theory that briefly led a few biologists astray. However, for the first quarter of the twentieth century it attracted considerable attention from both professional biologists and laypeople. De Vries's theory--together with the plant, Oenothera lamarckiana, that had supplied most of his evidence--became the focus of a surprising variety of imaginative hopes. Scientists and their various publics were fascinated by the utopian possibilities that the primrose seemed to offer, and their discussions shaped a public culture around biology that would help define the twentieth century as the "century of the gene." From a conventional history of science perspective (which, in the case of twentieth-century biology, often remains focused on the content of scientific theories and the professional communities that shaped them), the mutation theory seems unimportant. However, while De Vries's new theory of evolution ultimately failed to persuade the scientific community, it was much more important than is now realized, particularly because it helped make biology part of a wide variety of public debates. Understanding the mutation theory's story more fully suggests that we may need to rethink much of the rest of the century of the gene's history, to think less in terms of what happened in the lab and more about how biology came to function as public culture.

    The Northern Mockingbird (Mimus polyglottos) is a common bird in the southern United States that has been expanding its breeding range into the northern United States and southern Canada. During the twentieth century, there were 128 reports of Northern Mockingbird occurrences in North Dakota, including 106 reports during the breeding season (15 April to 31 August) and 22 during the nonbreeding season (1 September to 14 April). The species has been largely absent from North Dakota from January through mid-April. Prior to the 1930s, there was only one record (1916) of the Northern Mockingbird in the state. Observations of Northern Mockingbirds in North Dakota increased markedly between the 1930s and 1990s. On average, there were 0.3 reports of mockingbirds per year in 1931-1940, 0.6 in 1941-1950, 1.1 in 1951-1960, 1.6 in 1961-1970, 2.4 in 1971-1980, 2.3 in 1981-1990, and 4.5 in 1991-2000. The species has been observed in North Dakota nearly annually since 1958. At least six reports during the twentieth century included evidence of nesting (nests or dependent young). Based on mockingbird records during the twentieth century, we designate the current status of the Northern Mockingbird in North Dakota as a rare spring migrant, rare summer visitant, casual nester, and a casual fall and winter visitant.

  14. American Influence on Chinese Physics Study in the Early Twentieth Century

    NASA Astrophysics Data System (ADS)

    2016-01-01

    To save China from the perils she faced in the early twentieth century, the majority of the Chinese seemed to agree that it was necessary to strengthen the country by developing shiye or industry and commerce. For this purpose, they overhauled China's education system and sent a large number of students to study overseas. Many of them enrolled in American colleges, sponsored either by governmental grants or by private funds. As American physics advanced rapidly during the early twentieth century, Chinese physicists studying in top US institutions received first-class professional training. They later went on to become a main driving force in Chinese physics development. The study-in-America programs were apparently more successful than other study-overseas programs. Among other factors, the historical lessons learned from the aborted Chinese Educational Mission in the 1870s, the prevalent and long-time presence of American mission schools in China, and stable public and private funding contributed to their success. American-trained Chinese physicists not only advanced physics study in China but also played leading roles in the development of Chinese science and technology during the twentieth century. This fertile and far-reaching American influence has been embedded in all their accomplishments.

    Commission 12 covers research on the internal structure and dynamics of the Sun, the "quiet" solar atmosphere, solar radiation and its variability, and the nature of relatively stable magnetic structures like sunspots, faculae and the magnetic network. There is considerable productive overlap with the other Commissions of Division II as investigations move progressively toward the fertile intellectual boundaries between traditional research disciplines. In large part, the solar magnetic field provides the linkage that connects these diverse themes. The same magnetic field that produces the more subtle variations of solar structure and radiative output over the 11 yr activity cycle is also implicated in rapid and often violent phenomena such as flares, coronal mass ejections, prominence eruptions, and episodes of sporadic magnetic reconnection.The last three years have again brought significant progress in nearly all the research endeavors touched upon by the interests of Commission 12. The underlying causes for this success remain the same: sustained advances in computing capabilities coupled with diverse observations with increasing levels of spatial, temporal and spectral resolution. It is all but impossible to deal with these many advances here in anything except a cursory and selective fashion. Thankfully, the Living Reviews in Solar Physics; has published several extensive reviews over the last two years that deal explicitly with issues relevant to the purview of Commission 12. The reader who is eager for a deeper and more complete understanding of some of these advances is directed to http://www.livingreviews.org for access to these articles.

  10. Alternatives to Dam Building: Deindustrialization and the Redevelopment of Waterways in the Northeast During the Twentieth Century

    The Northeast United States contains more dams than any other region in the country but it lacks structures on the scale of the Hoover or Bonneville dams in the American West. This work addresses why the Northeast lacks such large dams and how the pattern of small dams within the region shaped its social development. During the twentieth century, changing social and economic conditions rendered the initial purposes of many dams in the region moot, but these structures continued to influence hydrologic conditions and the provision of ecosystem services to an expanding population. The continued existence of many of these dams resulted from a worldview unable to conceive of dam removal as it did to the economic or environmental services provided by the structure. Documenting the process by which society developed alternatives to dam building in this region can contextualize the origins and contingent character of ideas about dam removal. The overarching theme in this process is the deindustrialization of the Northeast, which pitted the interests of industrial cities undergoing economic reorganization, emerging suburban communities, and growing service industries in the region. This paper considers changing attitudes toward dams as part of a four step process: (1) although the mill dams of the industrial revolution remained after electrification rendered manufacturers independent of direct water power in the early twentieth century, deindustrialization reshaped the political and legal responses to flooding by stregnthening the political and economic position of service industries and suburban residential interests; (2) the most tangible response to this development was proposed federal investment in dam building in the region between the 1930s and the 1950s; (3) political conflicts between local interests and federal proposals for dam construction slowed down the dam building process and enabled people to consider alternative strategies for flood control and power

    Primary Health Networks (PHNs) have been tasked with two key objectives to be achieved through commissioning. Public value aims can be achieved by developing operational capability in the context of an authorising environment. Public value will need to focus on system level outcomes from multiple perspectives, including a consumer perspective. The authorising environment will require policymakers to allow time for PHNs to mature into their role. It will require an environment of effective collaboration amongst multiple stakeholders including consumers. The operational capability will need to ensure highly competent managers and clinical leadership working in a symbiotic relationship. Although some Medicare Locals demonstrated commissioning capacity and capability, this will need to be scaled up at-pace in the new healthcare landscape in order for PHNs to optimally fulfil their roles.

    The Linac Coherent Light Source (LCLS) X-ray free electron laser project is currently under construction at the Stanford Linear Accelerator Center (SLAC). A new injector and upgrades to the existing accelerator were installed in two phases in 2006 and 2007. We report on the commissioning of the injector, the two new bunch compressors at 250MeV and 4.3 GeV, and transverse and longitudinal beam diagnostics up to the end of the existing linac at 13.6 GeV. The commissioning of the new transfer line from the end of the linac to the undulator is scheduled to start in November 2008 and for the undulator in March 2009 with first light to be expected in July 2009.

    The RHIC accelerator complex completed commissioning activities in 2000 and is presently operating for the first physics run. The complete ensemble of magnets was thus operating over an extended period for the first time. We review the magnet performance as well as relate machine performance characteristics and accelerator physics results to the various magnetic measurements made during the construction phase. The conclusions may be useful for the LHC Project.

  16. Population commission discusses international migration.

    PubMed

    1997-01-01

    At the 30th session of the Commission on Population and Development during February 24-28, 1997, international migration was the main topic, with special linkages between migration and development and on gender issues and the family. New and emerging issues were also considered. Members stressed the need for more reliable data on migration, the direction of migrants flows, and the characteristics of migrants. The Commission requested a task force on basic social services to hold a technical symposium of experts on international migration in 1998. Its chair, Dr. Nafis Sadik, said that migration issues should based on the reality of choice not on coercive measures or quotas. Almost half of the migrants globally are women. The Commission was given a new impetus by the International Conference on Population and Development held at Cairo in 1994. Migration pressures intensified in the second half of the 1980s and in the early 1990s, creating areas of concern: the negative impact of short-term migration on working conditions in host countries; migration pressures emanating from climatic change; the protection of migrant women and their children; the right of receiving countries to regulate access to their territory; the adverse consequences of forced migration; the situation of persons whose asylum claims have been rejected; the trafficking in women and children, prostitution and coercive adoption; and the sudden and massive arrival of refugees in need of international protection. The 1998 session of the Commission will feature the theme of health and mortality, with special emphasis on the linkages between health and development and on gender and age.

    PubMed

    Alexander, Sally

    2009-01-01

    This essay uses memory in the ancient and modern sense of the "inner life of thought" to describe the formation of generational memory in a modern professional family whose twentieth-century history has been fractured by migration, war, education, and divorce. It is about the power of feeling and law, which framed the practical freedoms of twentieth-century women's lives and introduced the modern citizen in the aftermath of universal suffrage and world war. The first part of the essay emphasizes the psychic dimension of bodily feeling and drive in the formation of memory; a dimension overlooked by oral history and social movements, yet confirmed by autobiography and memoir. My granddaughter's questions provoked resistance as well as family stories, and let me observe the thought process in a child. Social history, autobiography, and personal memory confirm the common experience of everyday life reaching back through generations of London families; folklore, commerce, and family story make narratives of dreams, hopes, terrors, and events; a child's comprehension of the outside world is grasped through curiosity, imagination, and play in which bodily feeling is as powerful as speech and prohibition to make meanings that flow between inner world and external reality. The second half of the essay reflects on Joan Riviere's description of the self. Leading British psychoanalyst, translator of Freud, writing in the 1950s, Riviere's language of the inner world resonates with the liberal social ethics -- empathy, public service, common good -- which underpinned women's and human rights mid-twentieth century and the egalitarian and reproduction reforms whose universalism has been challenged since the 1970s. Negative feeling is striking in Riviere's description of the self -- fear, shame, shock, and trauma, which are confirmed in memoir and autobiography. In contrast, liberal social democratic accounts of the time idealized English character. Today, the future uncertain

  20. In Referees We Trust? Controversies over Grant Peer Review in the Late Twentieth Century

    NASA Astrophysics Data System (ADS)

    Baldwin, Melinda

    While many accounts of external refereeing assume that it has been a consistent part of science since the seventeenth century, the practice developed far more slowly and haphazardly than many observers realize, and it was not until after the Second World War that ''peer review'' became considered an essential part of scientific publishing or grant-making. This talk will explore refereeing procedures at American grant-giving organizations in the twentieth century, focusing especially on the National Science Foundation and the National Institutes of Health. The creators of the NSF and the NIH put refereeing systems in place at their foundation. However, the form and function of these systems differed from modern ''peer review'' in several important ways. At the NSF the initial purpose of the referee process was to advise the NSF program directors, not to dictate funding decisions. At the NIH, small ''study sections'' devoted to particular subjects made recommendations to the NIH leadership, which rendered final judgments. However, beginning in the 1960s a series of controversies about NIH and NSF grants placed refereeing procedures at these organizations under more intense scrutiny. These debates culminated in six days of Special Oversight Hearings into the NSF's peer review process in the summer of 1975. Following the hearings, both the NSF and NIH reformed their review processes to place more emphasis on referees' opinions about grant proposals, making peer review increasingly responsible for decision-making. These controversies illustrate that refereeing continued to undergo significant changes in form and purpose throughout the twentieth century, and further suggest that both the scientific community and the public placed increased emphasis on the role of the referee during the late twentieth century.

    Ettlinger, N; Archer, J C

    1987-09-01

    "In this paper we trace and interpret changes in the geographical pattern and city-size distribution of the world's largest cities in the twentieth century. Since 1900 the geographical distribution of these cities has become increasingly dispersed; their city-size distribution by rank was nearly linear in 1900 and 1940, and convex in 1980. We interpret the convex distribution which emerged following World War 2 as reflecting an economically integrated but politically and demographically partitioned global urban system. Our interpretation of changes in size distribution of cities emphasizes demographic considerations, largely neglected in previous investigations, including migration and relative rates of population change."

  2. Wheeler and Whitehead: Process Biology and Process Philosophy in the Early Twentieth Century.

    PubMed

    Sölch, Dennis

    2016-07-01

    The case of William Morton Wheeler and Alfred North Whitehead represents a striking example of how biologists and philosophers engaged in a common enterprise in the early twentieth century. Both challenge the notion that the living world is composed of distinct organisms. Based on his studies of the behavior of social insects, Wheeler developed a concept of superorganisms that paved the way for a theory of emergent evolution. This paper argues that Whitehead, whose relation to academic biology has been largely ignored, drew on Wheeler's findings and integrated them into a universal philosophical cosmology. PMID:27477347

The work of five of them, Ida Bengtson (1881-1952), Muriel Robertson (1883-1973), Hilda Sikora (1889-1974), Hélène Sparrow (1891-1970) and Clara Nigg (1897-1986), is reviewed and the names of several others are mentioned. The lives of these women seem typical of rickettsiologists and reflect the disasters that befell the world during the first half of the twentieth century.

  4. Melancholia before the twentieth century: fear and sorrow or partial insanity?

    PubMed

    Telles-Correia, Diogo; Marques, João Gama

    2015-01-01

    Throughout the history of psychopathology, several meanings have been assigned to the term melancholia. The main ones were related to affective disorders (fear and sadness) and abnormal beliefs. At the time of Hippocrates melancholia was regarded mainly in its affective component. Since that time, and until the eighteenth century, authors and opinions have been divided, with both aspects (affective disorders and abnormal beliefs), being valued. Finally, in the eighteenth to nineteenth centuries, with Pinel at its peak, melancholia becomes exclusively a synonym of abnormal beliefs. At the turn of the nineteenth to the twentieth century, the affective component returns as the main aspect characterizing melancholia.

  5. Pain, sympathy and the medical encounter between the mid eighteenth and the mid twentieth centuries

    PubMed Central

    2014-01-01

    Witnessing people in pain inevitably elicits anxiety in physicians and other caregivers. Physicians are often required to inflict certain types of discomforts in order to alleviate other, more destructive, pains. Accusations that physicians lacked sympathy can be heard throughout the centuries. This article explores the diverse medical responses to such claims between the eighteenth and twentieth centuries. It interrogates changing definitions of clinical sympathy. The concept of sympathy was continually being reworked for each generation of medical professional. Crucially, in this reworking, philosophers (such as Adam Smith) and physicians came into dialogue. Cultures of sympathy were understood in both physiological and metaphorical terms, and were tied to changing notions of professionalization PMID:24489439

    "The article analyzes the role of families in processes of rural-urban migration in India in the twentieth century. It shows that the continuous circular form of this migration should be explained as a consequence of rural family strategies. Already established kinship relations or marriage opportunities in the future act as a centripetal force, drawing the labor migrants back to their communities time and again. In addition, the article shows how labor migration is informed by economic and cultural considerations which determine the socioeconomic behavior of men and women." PMID:12293228

    For most of the twentieth century the central theme in the history of health policy in the United States was the elaboration and implementation of a consensus that health services should be organized in regional hierarchies. This consensus was based on shared beliefs about how medical advances were made and disseminated. Hierarchical regionalism became national health policy in several stages that culminated in the 1960s. Since the 1970s, however, the national policy of hierarchical regionalism has been eroded by the unexpected consequences of its success.

    In today's societies, successful new medical imaging technologies have focused unprecedented attention on the inside of the human body. These techniques have jumped the walls of the biomedical field per se, penetrating the fields of culture and law. The article traces a genealogy of twentieth-century medical techniques used to visualize the human body and brain, from X-rays to the more sophisticated CTs, MRIs, and PET scans. It explores the changes that these ever more numerous visualization techniques have occasioned in our corporality and examines how these technologies have been received in the courtroom and in popular culture, especially in literature, movies, and magazines.

    Objective to discuss the conditions that enabled home care at the beginning of the twentieth century. Method study of the genealogic inspiration on home care. The empirical material consisted of legal documents on the subject that were published in the Official Journal. The documents were studied using analytical tools, such as Power, Discipline and Biopolitics, which were inspired in Foucault. Results two analytical categories were established, "home inspection: visiting nurses and tuberculosis" and "records: political and economic apparatus". Final considerations tuberculosis, the new profession of visiting nurses, inspection records and the detailed analysis of the cities grant home care a nature of surveillance, inspection and control to conduct the behaviour of individuals.

  11. Our Environment in Miniature: Dust and the Early Twentieth-Century Forensic Imagination

    PubMed Central

    BURNEY, IAN

    2013-01-01

    This article explores the articulation of the crime scene as a distinct space of theory and practice in the early twentieth century. In particular it focuses on the evidentiary hopes invested in what would at first seem an unpromising forensic object: dust. Ubiquitous and, to the uninitiated, characterless, dust nevertheless featured as an exemplary object of cutting-edge forensic analysis in two contemporary domains: writings of criminologists and works of detective fiction. The article considers how in these texts dust came to mark the furthest reach of a new forensic capacity they were promoting, one that drew freely upon the imagination to invest crime scene traces with meaning.

  12. [Constant or break? On the relations between human genetics and eugenics in the Twentieth Century].

    PubMed

    Germann, Pascal

    2015-07-01

    The history of human genetics has been a neglected topic in history of science and medicine for a long time. Only recently, have medical historians begun to pay more attention to the history of human heredity. An important research question deals with the interconnections between human genetics and eugenics. This paper addresses this question: By focusing on a Swiss case study, the investigation of the heredity of goiter, I will argue that there existed close but also ambiguous relations between heredity research and eugenics in the twentieth century. Studies on human heredity often produced evidence that challenged eugenic aims and ideas. Concurrently, however, these studies fostered visions of genetic improvement of human populations.

    During launch and early operation of the Global Precipitation Measurement (GPM) Mission, the Guidance, Navigation and Control (GNC) analysis team encountered four main on orbit anomalies. These include: (1) unexpected shock from Solar Array deployment, (2) momentum buildup from the Magnetic Torquer Bars (MTBs) phasing errors, (3) transition into Safehold due to albedo-induced Course Sun Sensor (CSS) anomaly, and (4) a flight software error that could cause a Safehold transition due to a Star Tracker occultation. This paper will discuss ways GNC engineers identified and tracked down the root causes. Flight data and GNC on board models will be shown to illustrate how each of these anomalies were investigated and mitigated before causing any harm to the spacecraft. On May 29, 2014, GPM was handed over to the Mission Flight Operations Team after a successful commissioning period. Currently, GPM is operating nominally on orbit, collecting meaningful scientific data that will significantly improve our understanding of the Earth's climate and water cycle.

    IAU Commission 28 (IAU C28: Galaxies) was founded in the late 1930s at which time it had only a small membership (see the historical notes by Sadler et al. 2007). When C28 ended its existence in 2015 there were well over 1000 members on its books. The membership had grown to the point where the effort to keep track of active participants had become a major task. During the C28s tenure 27 IAU Symposia have been devoted to galaxies, the third highest number (Mickaelian 2014)

  2. Pioneers of Gentrification: Transformation in Global Neighborhoods in Urban America in the Late Twentieth Century.

    PubMed

    Hwang, Jackelyn

    2016-02-01

    Few studies have considered the role of immigration in the rise of gentrification in the late twentieth century. Analysis of U.S. Census and American Community Survey data over 24 years and field surveys of gentrification in low-income neighborhoods across 23 U.S. cities reveal that most gentrifying neighborhoods were "global" in the 1970s or became so over time. An early presence of Asians was positively associated with gentrification; and an early presence of Hispanics was positively associated with gentrification in neighborhoods with substantial shares of blacks and negatively associated with gentrification in cities with high Hispanic growth, where ethnic enclaves were more likely to form. Low-income, predominantly black neighborhoods and neighborhoods that became Asian and Hispanic destinations remained ungentrified despite the growth of gentrification during the late twentieth century. The findings suggest that the rise of immigration after 1965 brought pioneers to many low-income central-city neighborhoods, spurring gentrification in some neighborhoods and forming ethnic enclaves in others.

    2006-04-01

    Twentieth-century warming could lead to increases in the moisture-holding capacity of the atmosphere, altering the hydrological cycle and the characteristics of precipitation. Such changes in the global rate and distribution of precipitation may have a greater direct effect on human well-being and ecosystem dynamics than changes in temperature itself. Despite the co-variability of both of these climate variables, attention in long-term climate reconstruction has mainly concentrated on temperature changes. Here we present an annually resolved oxygen isotope record from tree-rings, providing a millennial-scale reconstruction of precipitation variability in the high mountains of northern Pakistan. The climatic signal originates mainly from winter precipitation, and is robust over ecologically different sites. Centennial-scale variations reveal dry conditions at the beginning of the past millennium and through the eighteenth and early nineteenth centuries, with precipitation increasing during the late nineteenth and the twentieth centuries to yield the wettest conditions of the past 1,000 years. Comparison with other long-term precipitation reconstructions indicates a large-scale intensification of the hydrological cycle coincident with the onset of industrialization and global warming, and the unprecedented amplitude argues for a human role.

  5. Labs in the field? Rocky mountain biological stations in the early twentieth century.

    PubMed

    Vetter, Jeremy

    2012-01-01

    Biological field stations proliferated in the Rocky Mountains region of the western United States during the early decades of the twentieth century. This essay examines these Rocky Mountain field stations as hybrid lab-field sites from the perspective of the field side of the dichotomy: as field sites with raised walls rather than as laboratories whose walls with the natural world have been lowered. Not only were these field stations transformed to be more like laboratories, but they were also embedded within the particular regional environmental and institutional context of the Rocky Mountains. Using the University of Colorado's Mountain Laboratory at Tolland and other contemporaneous sites as examples, this essay analyzes key features of these sites, including their location within transportation networks, buildings, equipment, personnel, scheduling, recreational and social activities, and other material and social practices on the ground. Considering both the distinctive and shared characteristics of the Rocky Mountain field stations in comparison to other types of field stations provides a more complete picture of the diversity and range of lab-field hybrid sites in the biological sciences in the early twentieth-century United States.

    2008-10-01

    The Oak Ridge Rutgers University Barrel Array (ORRUBA) is a silicon detector array being developed by the Center of Excellence for Stewardship Science at Oak Ridge National Laboratory. The array is comprised of two rings of position-sensitive detectors in a cylindrical setup designed to maximize solid angle coverage for (d,p) measurements in inverse kinematics. Each detector has 4 resistive strips, with readout from each strip-end. At forward angles, detector telescopes are used, comprised of a thin non-resistive detector (65μm) for transmission backed by the thicker resistive detector (1000μm) for stopping, allowing particle identification in addition to measurement of the angle and energy of the detected particles. For commissioning, the profile of each detector must be tested to insure that it is functioning properly, and to understand its optimal bias voltage and energy resolution. Measurements of leakage current profiles, full-depletion voltages and energy resolution measurements have been completed. The details of the array, its motivation and these commissioning measurements will be reported.

    2005-02-01

    This article takes a brief look at the benefits of commissioning and describes a vision of the future where most of the objectives of commissioning will be accomplished automatically by capabilities built into the building systems themselves. Commissioning will become an activity that's performed continuously rather than periodically, and only repairs requiring replacement or overhaul of equipment will require manual intervention. The article then identifies some of the technologies that will be needed to realize this vision and ends with a call for all involved in the enterprise of building commissioning and automation to embrace and dedicate themselves to a future of automated commissioning.

  13. Commissioning neuropsychiatry services: barriers and lessons.

    PubMed

    Bhattacharya, Rahul; Rickards, Hugh; Agrawal, Niruj

    2015-12-01

    Aims and method Previous studies have shown variations in commissioning of neuropsychiatry services and this makes access to neuropsychiatric services a post-code lottery. In this survey, we approached all mental health and neuropsychiatric service commissioners within London to map current funding and commissioning arrangements, and explored perceived barriers to neuropsychiatric service commissioning. Results 83% of commissioners within London responded. There was significant variability between neuropsychiatric services commissioned through the mental health stream. Contracting arrangements were variable. Lack of earmarked fund for neuropsychiatry and disjointed funding stream for such services were identified by commissioners as a barrier, as was the critical mass of neuropsychiatric cases. Clinical implications Neuropsychiatric service development continues to be hindered by lack of clear commissioning process. Strategic drive is needed to promote more equitable neuropsychiatric services. National or regional commissioning covering a large population will provide a better model for neuropsychiatric services to be commissioned. PMID:26755989

In this report, we will review the progress of these topics in the past three years. There are many remarkable topics, such as Time scales, Atomic clock development, Time transfer, Future UTC and future redefinition of the second. Among them, scientific highlights are the progress of pulsar time scales and the optical frequency standards. On the other hand, as the social convention, change in the definition of UTC and the second is important.

  15. Automated Demand Response and Commissioning

    This paper describes the results from the second season of research to develop and evaluate the performance of new Automated Demand Response (Auto-DR) hardware and software technology in large facilities. Demand Response (DR) is a set of activities to reduce or shift electricity use to improve the electric grid reliability and manage electricity costs. Fully-Automated Demand Response does not involve human intervention, but is initiated at a home, building, or facility through receipt of an external communications signal. We refer to this as Auto-DR. The evaluation of the control and communications must be properly configured and pass through a set of test stages: Readiness, Approval, Price Client/Price Server Communication, Internet Gateway/Internet Relay Communication, Control of Equipment, and DR Shed Effectiveness. New commissioning tests are needed for such systems to improve connecting demand responsive building systems to the electric grid demand response systems.

  16. Search for invisible nucleon decay in SNO + during commissioning phase

    2015-04-01

    The SNO + experiment aims to explore several topics in neutrino physics, including neutrinoless double beta decay and low energy solar neutrinos. For its initial commissioning phase, SNO + will fill its inner vessel with light water and run to evaluate the performance of the detector and electronics. During this water-fill phase, it will have a unique sensitivity to certain modes of invisible nucleon decay, where the nucleon decays to a mode in which the decay products are not detected, e.g. to 3 neutrinos. With just a couple of months of water running, SNO + is expected to set an improved model independent limit on the current bounds.

  17. Domination, subordination and struggle: middle-class marriage in early twentieth-century Wolverhampton, England.

    2010-01-01

    The aim of the article is to modify our understanding of the history of middle-class marriage. It draws upon the detailed examination of one Wolverhampton couple's marriage to explore relationships between husbands and wives-and between ex-husbands and ex-wives-in early twentieth-century provincial England. It argues that patriarchal and companionate marriages co-existed alongside one another; that even in patriarchal marriages wives were prepared to seek legal redress for their grievances; and that even in insular and unfashionable regions of the country such as the Black Country the courts, both civil and criminal, policed masculinity and femininity in their assessment of where fault lay.

    Drought is a significant natural hazard that slowly evolves over time. Because of its character, drought is difficult to monitor and impacts are often poorly documented. Agriculture is one of the most sensitive sectors that are prone to drought. The objective of this research is to assess the impacts of drought on soybean production and revenue in Kentucky. Soybeans are one of Kentucky's most important commodities. In this study, impacts of 1930-1931, 1940-1942, 1952-1955, 1987-1988, 1999-2000, and 2007 droughts were considered. It was found that over the recent years, up to 56 % of the revenue from soybeans was lost due to drought. During the first half of the twentieth century, revenue loss reached up to 77 %. This research is valuable to the general public as well as planners and policy makers. Proper documentation of impacts of past droughts will help identify drought vulnerabilities and results in better risk management and mitigation.

    Although the public health impact of direct-to-consumer (DTC) pharmaceutical advertising remains a subject of great controversy, such promotion is typically understood as a recent phenomenon permitted only by changes in federal regulation of print and broadcast advertising over the past two decades. But today's omnipresent ads are only the most recent chapter in a longer history of DTC pharmaceutical promotion (including the ghostwriting of popular articles, organization of public-relations events, and implicit advertising of products to consumers) stretching back over the twentieth century. We use trade literature and archival materials to examine the continuity of efforts to promote prescription drugs to consumers and to better grapple with the public health significance of contemporary pharmaceutical marketing practices.

  20. Farm crisis and rural revitalization in south-central New York during the early twentieth century.

    2010-01-01

    In contrast to both the critique of rural backwardness made by the Country Life Movement and the lament about rural declension expressed by proponents of agrarianism, the history of the Nanticoke Valley of south-central New York State demonstrates the possibilities for rural revitalization that lay in connections between the countryside and the city. In the early twentieth century, as long-settled families departed for urban employment, European immigrant families escaping the mines and mills bought abandoned farms. Motorized transport enabled farming families to send household members to the city each day and furnished them with a local market for their produce. This flexible combination of subsistence production, wage labor, and petty commodity production revitalized the rural economy and sustained the community in spite of the consolidation of the dairy industry. This essay explores the social changes that accompanied this profound reorientation of local life.

  1. Did the 1918 influenza cause the twentieth century cardiovascular mortality epidemic in the United States?

    2016-01-01

    During most of the twentieth century, cardiovascular mortality increased in the United States while other causes of death declined. By 1958, the age-standardized death rate (ASDR) for cardiovascular causes for females was 1.84 times that for all other causes, combined (and, for males, 1.79×). Although contemporary observers believed that cardiovascular mortality would remain high, the late 1950s and early 1960s turned out to be the peak of a roughly 70-year epidemic. By 1988 for females (1986 for males), a spectacular decline had occurred, wherein the ASDR for cardiovascular causes was less than that for other causes combined. We discuss this phenomenon from a demographic point of view. We also test a hypothesis from the literature, that the 1918 influenza pandemic caused the cardiovascular mortality epidemic; we fail to find support. PMID:27761328

    The history of human genetics has been a neglected topic in history of science and medicine for a long time. Only recently, have medical historians begun to pay more attention to the history of human heredity. An important research question deals with the interconnections between human genetics and eugenics. This paper addresses this question: By focusing on a Swiss case study, the investigation of the heredity of goiter, I will argue that there existed close but also ambiguous relations between heredity research and eugenics in the twentieth century. Studies on human heredity often produced evidence that challenged eugenic aims and ideas. Concurrently, however, these studies fostered visions of genetic improvement of human populations.

    In 2008 I chanced upon the lonely grave of Dr. William Theodore Hodge, buried in 1934, in the Derby Pioneer and Aboriginal Cemetery. He turned out to be the founding doctor of the practice in which I have worked for the past thirty years. Dr. Hodge migrated from England in 1896. He was the first western trained doctor to work in the Perth suburb of Claremont and in the wheat-belt town of Kellerberrin. He was an innovative and inventive modern doctor who became a legend in the Kimberley where he died tragically, on the day prior to his retirement, at the age of seventy-five. His story is illustrative of the life and medical practice of a pioneering doctor in metropolitan, rural, and remote practice in Western Australia at the end of the nineteenth and the early years of the twentieth centuries.

  5. Birth Attendants and Midwifery Practice in Early Twentieth-century Derbyshire

    2012-01-01

    Summary The 1902 Midwives Act introduced training and supervision for midwives in England and Wales, outlawing uncertified-and-untrained midwives (handywomen) and phasing out certified-but-untrained (bona fide) midwives. This paper compares the numbers and practices of these two different types of birth attendant with each other, with qualified and certified midwives and with doctors in early twentieth-century Derbyshire during this period of change, and examines the spatial and social factors influencing women's choice of birth attendant. It finds that the new legislation did not entirely eliminate continuity in traditional practices and allegiance, and that both social and spatial factors governed the choice of delivery attendant, with fewer midwives available in rural areas and a surviving network of untrained bona fide midwives in mining communities. Within this spatial pattern, however, although wealthier women were more likely to have chosen a doctor or a qualified midwife, familiarity and loyalty allowed bona fide midwives to maintain their case loads.

  6. Under the trees: the Georgia peach and the quest for labor in the twentieth century.

    PubMed

    Okie, Tom

    2011-01-01

    The Georgia peach boom around the turn of the twentieth century was often hailed as a successful experiment in diversification. Peach growers, the story went, threw off the tyranny of King Cotton by pledging their allegiance to the "Queen of Fruits." This portrayal is partly true; unlike other proposed alternatives to cotton, peaches flourished in many places. But the history of the "labor problem" in the Georgia peach belt makes it clear that peach production depended on the cotton economy. Peaches required large amounts of labor only at harvest time, which came during a lull in the cotton season. Thus, for many years, growers found a ready labor supply in a rural population otherwise at loose ends. As this population relocated to cities, and as cotton farmers mechanized their operations, peach growers turned increasingly to the federal government to help shore up their workforces.

    The early twentieth-century transformations of rural Chinese women’s work have received relatively little direct attention. By contrast, the former custom of footbinding continues to fascinate and is often used to illustrate or contest theories about Chinese women’s status. Arguing that for rural women at least, footbinding needs to be understood in relation to rural economic conditions, the authors focus on changes in textile production and in footbinding in two counties in Shaanxi province. Drawing on historical sources and their own interview data from rural women who grew up in this period, the authors find evidence that transformations in textile production undercut the custom of footbinding and contributed to its rapid demise.

  8. Medical confidentiality in the late nineteenth and early twentieth centuries: an Anglo-German comparison1

    2012-01-01

    Summary Professional secrecy of doctors became an issue of considerable medico-legal and political debate in the late nineteenth and early twentieth centuries in both Germany and England, although the legal preconditions for this debate were quite different in the two countries. While in Germany medical confidentiality was a legal obligation and granted in court, no such statutory recognition of doctors’ professional secrecy existed in England. This paper is a comparative analysis of medical secrecy in three key areas - divorce trials, venereal disease and abortion - in both countries. Based on sources from the period between c.1870 and 1939, our paper shows how doctors tried to define the scope of professional secrecy as an integral part of their professional honour in relation to important matters of public health.

    Gausemeier, Bernd

    2015-01-01

    This article discusses the development of the statistical methods employed by psychiatrists to study heredity as a causative factor of mental diseases. It argues that psychiatric asylums and clinics were the first institutions in which human heredity became the object of systematic research. It also highlights the different concepts of heredity prevalent in the psychiatric community. The first of four parts traces how heredity became a central category of asylum statistics in the first half of the nineteenth century. The second part deals with attempts to introduce new methods of surveying in order to generate more precise data about psychopathological inheritance in the 1860s and 1870s. The third part discusses how, by the end of the nineteenth century, a widespread discontent with the results of asylum statistics led to an increasing interest in the use of family studies. Finally, the fourth part examines the impact of Mendelian theory on psychiatric statistics in the early twentieth century.

  10. African American southerners and white physicians: medical care at the turn of the twentieth century.

    PubMed

    Pohl, Lynn Marie

    2012-01-01

    Much of what scholars know about race and medicine in the late-nineteenth-and early-twentieth-century South relates to the racial beliefs of white physicians and the segregated and exploitative treatment of black patients in hospitals and public health programs. This article shifts scholarly attention to the ways African American patients and their families took part in medical practice in commonplace settings of the home and office. The author examines how African Americans called upon local physicians in the rural and small-town South, how white physicians responded, and how they interacted in cases of serious illness, injury, and surgery. The claims of black southerners to physicians' treatments, in combination with small-town physicians' continuing reliance on interpersonal practices of medical care, made for an erratic but potentially distinctive cross-racial encounter-one involving a greater degree of negotiated authority and personal care than what generally has been recognized for this time and place.

    2007-07-01

    In 1952, the University of Michigan physiologist Robert Gesell shocked his colleagues at the business meeting of the American Physiological Society by reading a prepared statement in which he claimed that some of the animal experimentation being carried out by scientists was inhumane. He especially attacked the National Society for Medical Research (NSMR), an organization that had been founded to defend animal experimentation. This incident was part of a broader struggle taking place at the time between scientists and animal welfare advocates with respect to what restrictions, if any, should be placed on animal research. A particularly controversial issue was whether or not pound animals should be made available to laboratories for research. Two of the prominent players in this controversy were the NSMR and the Animal Welfare Institute, founded and run by Gesell's daughter, Christine Stevens. This article focuses on the interaction between these two organizations within the broader context of the debate over animal experimentation in the mid-twentieth century.

  13. Social Skills: Adolf Meyer's Revision of Clinical Skill for the New Psychiatry of the Twentieth Century.

    Lamb, Susan

    2015-07-01

    Adolf Meyer (1866-1950) exercised considerable influence over the development of Anglo-American psychiatry during the first half of the twentieth century. The concepts and techniques he implemented at his prominent Phipps Psychiatric Clinic at Johns Hopkins remain important to psychiatric practice and neuro-scientific research today. In the 1890s, Meyer revised scientific medicine's traditional notion of clinical skill to serve what he called the 'New Psychiatry', a clinical discipline that embodied social and scientific ideals shared with other 'new' progressive reform movements in the United States. This revision conformed to his concept of psychobiology - his biological theory of mind and mental disorders - and accorded with his definition of scientific medicine as a unity of clinical-pathological methods and therapeutics. Combining insights from evolutionary biology, neuron theory and American pragmatist philosophy, Meyer concluded that subjective experience and social behaviour were functions of human biology. In addition to the time-honoured techniques devised to exploit the material data of the diseased body - observing and recording in the clinic, dissecting in the morgue and conducting histological experiments in the laboratory - he insisted that psychiatrists must also be skilled at wielding social interaction and interpersonal relationships as investigative and therapeutic tools in order to conceptualise, collect, analyse and apply the ephemeral data of 'social adaptation'. An examination of his clinical practices and teaching at Johns Hopkins between 1913 and 1917 shows how particular historical and intellectual contexts shaped Meyer's conceptualisation of social behaviour as a biological function and, subsequently, his new vision of clinical skill for twentieth-century psychiatry.

  14. Building Baluchitherium and Indricotherium: imperial and international networks in early-twentieth century paleontology.

    PubMed

    Manias, Chris

    2015-01-01

    Over the first decades of the twentieth century, the fragmentary remains of a huge prehistoric ungulate were unearthed in scientific expeditions in India, Turkestan and Mongolia. Following channels of formal and informal empire, these were transported to collections in Britain, Russia and the United States. While striking and of immense size, the bones proved extremely difficult to interpret. Alternately naming the creature Paraceratherium, Baluchitherium and Indricotherium, paleontologists Clive Forster-Cooper, Alexei Borissiak and Henry Fairfield Osborn struggled over the reconstruction of this gigantic fossil mammal. However, despite these problems, shared work on the creature served as a focus for collaboration and exchange rather than rivalry between these three scientific communities. Not only did the initial interpretation and analysis depend on pre-existing connections between British and American paleontological institutions, but the need for comparative material, recognition and contacts brought British and American scholars into communication and exchange with their counterparts in the Soviet Union. This article examines these processes. It first uses these excavations as a comparative case-study of different manifestations of colonial science in this period, examining how scholars in the Britain, the Russian Empire and the United States used formal and informal colonial links to Asia to pursue new research. It then moves to examine how the common problem of reconstructing this giant animal drew metropolitan scientific communities together, at least for a time. The construction of the Baluchitherium and Indricotherium illustrates the drives to expand research both imperially and internationally in the early-twentieth century, but also the continual problems in resources, institutionalization, transport and communication that could run up against scientific work.

    Granato, Marcus

    The first systematic asronomical observations in the southern hemisphere were in Pernambuco, northeastern Brazil, in the short period of Dutch rule in the region (1637-1644). Later, in the late nineteenth and early twentieth centuries, there were three observatories on Brazilian soil: Imperial Observatório do Rio de Janeiro, Observatório da Escola Politecnica, both in Rio de Janeiro and Observatório Central, in the southern city of Porto Alegre. The first was created by Imperial decree by D. Pedro I, on 15 October 1827, while the second, linked to Universidade do Brasil, was established on 5 July 1881. The third was planned in 1889, but only inaugurated on 24 January 1908 as part of the Escola de Engenharia. All three institutions exist to this day, and their scientific instruments of historical value are included in cultural heritage preservation projects. The largest collection of this kind of objects is at Museu de Astronomia e Ciéncias Afins (MAST), most of whose 2000 artefacts come from the Imperial Observatory (today the National Observatory). Many of them were produced in Germany by manufacturers such as Gustav Heyde, Carl Zeiss, Askania-Werke, Carl Bamberg and Max Kohl. The buildings of the Observatório Central (1921) and Observatório Nacional (1921) are listed by federal and state heritage protection agencies, particularly because they were purpose built for astronomical research and have architectural features typical of the late nineteenth and early twentieth centuries that have not been altered over the years.

    If science has the equivalent of a Bloomsbury group, it is the five men born at the turn of the twentieth century in Budapest: Theodore von Kármán, Leo Szilard, Eugene Wigner, John von Neumann, and Edward Teller. From Hungary to Germany to the United States, they remained friends and continued to work together and influence each other throughout their lives. As a result, their work was integral to some of the most important scientific and political developments of the twentieth century. They were an extraordinary group of talents: Wigner won a Nobel Prize in theoretical physics; Szilard was the first to see that a chain reaction based on neutrons was possible, initiated the Manhattan Project, but left physics to try to restrict nuclear arms; von Neumann could solve difficult problems in his head and developed the modern computer for more complex problems; von Kármán became the first director of NASA's Jet Propulsion Laboratory, providing the scientific basis for the U.S. Air Force; and Teller was the father of the hydrogen bomb, whose name is now synonymous with the controversial "Star Wars" initiative of the 1980s. Each was fiercely opinionated, politically active, and fought against all forms of totalitarianism. István Hargittai, as a young Hungarian physical chemist, was able to get to know some of these great men in their later years, and the depth of information and human interest in The Martians of Science is the result of his personal relationships with the subjects, their families, and their contemporaries.

    The emergence of neurology as a separate specialty from internal medicine and psychiatry took several decades, starting at the end of the nineteenth century. This can be adequately reconstructed by focusing on the establishment of specialized journals, societies, university chairs, the invention and application of specific instruments, medical practices, and certainly also the publication of pivotal textbooks in the field. Particularly around 1900, the German-speaking countries played an integral role in this process. In this article, one aspect is extensively explored, notably the publication (in the twentieth century) of three comprehensive and influential multivolume and multiauthor handbooks entirely devoted to neurology. All available volumes of Max Lewandowsky's Handbuch der Neurologie (1910–1914) and the Handbuch der Neurologie (1935–1937) of Oswald Bumke and Otfrid Foerster were analyzed. The handbooks were then compared with Pierre Vinken's and George Bruyn's Handbook of Clinical Neurology (1968–2002). Over the span of nearly a century these publications became ever more comprehensive and developed into a global, encompassing project as is reflected in the increasing number of foreign authors. Whereas the first two handbooks were published mainly in German, “Vinken & Bruyn” was eventually published entirely in English, indicating the general changes in the scientific language of neurology after World War II. Distinctions include the uniformity of the series, manner of editorial involvement, thematic comprehensiveness, inclusion of volume editors in “Vinken & Bruyn,” and the provision of index volumes. The increasing use of authorities in various neurological subspecialties is an important factor by which these handbooks contrast with many compact neurological textbooks that were available at the time. For historiographical purposes, the three neurological handbooks considered here were important sources for the general study of the history of

  18. Fault interaction and stress triggering of twentieth century earthquakes in Mongolia

    Pollitz, F.; Vergnolle, M.; Calais, E.

    2003-01-01

    A cluster of exceptionally large earthquakes in the interior of Asia occurred from 1905 to 1967: the 1905 M7.9 Tsetserleg and M8.4 Bolnai earthquakes, the 1931 M8.0 Fu Yun earthquake, the 1957 M8.1 Gobi-Altai earthquake, and the 1967 M7.1 Mogod earthquake (sequence). Each of the larger (M ??? 8) earthquakes involved strike-slip faulting averaging more than 5 m and rupture lengths of several hundred kilometers. Available geologic data indicate that recurrence intervals on the major source faults are several thousands of years and distances of about 400 km separate the respective rupture areas. We propose that the occurrences of these and many smaller earthquakes are related and controlled to a large extent by stress changes generated by the compounded static deformation of the preceding earthquakes and subsequent viscoelastic relaxation of the lower crust and upper mantle beneath Mongolia. We employ a spherically layered viscoelastic model constrained by the 1994-2002 GPS velocity field in western Mongolia [Vergnolle et al., 2003]. Using the succession of twentieth century earthquakes as sources of deformation, we then analyze the time-dependent change in Coulomb failure stress (????f). At remote interaction distances, static ????f values are small. However, modeled postseismic stress changes typically accumulate to several tenths of a bar over time intervals of decades. Almost all significant twentieth century regional earthquakes (M ??? 6) with well-constrained fault geometry lie in positive ????f lobes of magnitude about +0.5 bar. Our results suggest that significant stress transfer is possible among continental faults separated by hundreds of kilometers and on timescales of decades.

  3. Twentieth-century atmospheric river activity along the west coasts of Europe and North America: algorithm formulation, reanalysis uncertainty and links to atmospheric circulation patterns

    NASA Astrophysics Data System (ADS)

    Brands, S.; Gutiérrez, J. M.; San-Martín, D.

    2016-04-01

    A new atmospheric-river detection and tracking scheme based on the magnitude and direction of integrated water vapour transport is presented and applied separately over 13 regions located along the west coasts of Europe (including North Africa) and North America. Four distinct reanalyses are considered, two of which cover the entire twentieth-century: NOAA-CIRES Twentieth Century Reanalysis v2 (NOAA-20C) and ECMWF ERA-20C. Calculations are done separately for the OND and JFM-season and, for comparison with previous studies, for the ONDJFM-season as a whole. Comparing the AR-counts from NOAA-20C and ERA-20C with a running 31-year window looping through 1900-2010 reveals differences in the climatological mean and inter-annual variability which, at the start of the twentieth-century, are much more pronounced in western North America than in Europe. Correlating European AR-counts with the North Atlantic Oscillation (NAO) reveals a pattern reminiscent of the well-know precipitation dipole which is stable throughout the entire century. A similar analysis linking western North American AR-counts to the North Pacific index (NPI) is hampered by the aforementioned poor reanalysis agreement at the start of the century. During the second half of the twentieth-century, the strength of the NPI-link considerably varies with time in British Columbia and the Gulf of Alaska. Considering the period 1950-2010, AR-counts are then associated with other relevant large-scale circulation indices such as the East Atlantic, Scandinavian, Pacific-North American and West Pacific patterns (EA, SCAND, PNA and WP). Along the Atlantic coastline of the Iberian Peninsula and France, the EA-link is stronger than the NAO-link if the OND season is considered and the SCAND-link found in northern Europe is significant during both seasons. Along the west coast of North America, teleconnections are generally stronger during JFM in which case the NPI-link is significant in any of the five considered

  4. SNS BEAM COMMISSIONING TOOLS AND EXPERIENCE

    SciTech Connect

    Shishlo, Andrei P; Galambos, John D

    2008-01-01

    The Spallation Neutron Source (SNS) successfully met the primary construction project completion milestones in April 2006. An important ingredient of this successful commissioning was the development and use of software tools. With the increasing digitalization of beam diagnostics and increasing complexity of Integrated Control Systems of large accelerators, the need for high level software tools is critical for smooth commissioning. At SNS a special Java based infrastructure called XAL was prepared for beam commissioning. XAL provides a hierarchal view of the accelerator, is data base configured, and includes a physics model of the beam. This infrastructure and individual applications development along with a historical time line of the SNS commissioning will be discussed.

  9. Monitoring and Commissioning Verification Algorithms for CHP Systems

    SciTech Connect

    Brambley, Michael R.; Katipamula, Srinivas; Jiang, Wei

    2008-03-31

    This document provides the algorithms for CHP system performance monitoring and commissioning verification (CxV). It starts by presenting system-level and component-level performance metrics, followed by descriptions of algorithms for performance monitoring and commissioning verification, using the metric presented earlier. Verification of commissioning is accomplished essentially by comparing actual measured performance to benchmarks for performance provided by the system integrator and/or component manufacturers. The results of these comparisons are then automatically interpreted to provide conclusions regarding whether the CHP system and its components have been properly commissioned and where problems are found, guidance is provided for corrections. A discussion of uncertainty handling is then provided, which is followed by a description of how simulations models can be used to generate data for testing the algorithms. A model is described for simulating a CHP system consisting of a micro-turbine, an exhaust-gas heat recovery unit that produces hot water, a absorption chiller and a cooling tower. The process for using this model for generating data for testing the algorithms for a selected set of faults is described. The next section applies the algorithms developed to CHP laboratory and field data to illustrate their use. The report then concludes with a discussion of the need for laboratory testing of the algorithms on a physical CHP systems and identification of the recommended next steps.

    2015-01-01

    During launch and early operation of the Global Precipitation Measurement (GPM) Mission, the Guidance, Navigation, and Control (GN&C) analysis team encountered four main on-orbit anomalies. These include: (1) unexpected shock from Solar Array deployment, (2) momentum buildup from the Magnetic Torquer Bars (MTBs) phasing errors, (3) transition into Safehold due to albedo induced Course Sun Sensor (CSS) anomaly, and (4) a flight software error that could cause a Safehold transition due to a Star Tracker occultation. This paper will discuss ways GN&C engineers identified the anomalies and tracked down the root causes. Flight data and GN&C on-board models will be shown to illustrate how each of these anomalies were investigated and mitigated before causing any harm to the spacecraft. On May 29, 2014, GPM was handed over to the Mission Flight Operations Team after a successful commissioning period. Currently, GPM is operating nominally on orbit, collecting meaningful scientific data that will significantly improve our understanding of the Earth's climate and water cycle.

    Although this guide focuses on the retrocommissioning process and its advantages, all three types of commissioning--retrocommissioning, commissioning, and recommissioning--play an equally important role in ensuring that buildings perform efficiently and provide comfortable, safe, and productive work environments for owners and occupants. For new construction and retrofit projects, commissioning should be incorporated early, during design, and last throughout the length of the project. For buildings that were never commissioned, the retrocommissioning process can yield a wealth of cost-saving opportunities while enhancing a building's environment. Finally, once a building is commissioned or retrocommissioned, incorporating recommissioning into the organization's O and M program (by periodically reapplying the original diagnostic testing and checklist procedures) helps ensure that cost savings and other benefits gained from the original process persist over time.

  14. BOOK REVIEW: Quantum Generations. A history of physics in the twentieth century

    NASA Astrophysics Data System (ADS)

    2000-03-01

    Physics has a long history, but more physics has been discovered in the twentieth century than in all previous eras together. That in itself would be a sufficient justification for a history of physics in the twentieth century, but the end of the previous century also marked a discontinuity, from Newtonian classical physics to relativity and quantum mechanics. If any single event marks the start of the process it is the discovery of x-rays in 1895, and Kragh's century spans from about 1895 to about 1995. It is, of course, too much for a single volume, even a large one, and Kragh recognizes from the outset that he has to be selective and concentrate on those subjects that define twentieth-century physics. For the early part of the century the author relies on carefully chosen secondary sources, to avoid the near-impossible task of absorbing a multitude of original papers. The recent period is more difficult, and the sources are articles, reviews, and the recollections of physicists. The book is in three main sections, roughly to the end of World War I, to the end of World War II, and up to 1995, plus a retrospective summary. It deals with more than just discoveries in physics, looking also at physicists and institutions, and at their interactions with the rest of society. The broad outlines of many discoveries are often known to physicists who have no special interest in history, and Kragh is careful to point out where these conventional accounts are inadequate. The first chapters set the scene at the end of the nineteenth century, acknowledging that there was a belief that all the grand underlying principles had been established, but also pointing out that there was a ferment of attempts to reinterpret physics in terms of concepts like vortices and hyperspaces. The history begins with the mould-breaking discoveries of x-rays, radioactivity and the electron. The chapters that follow look at theories about atomic structure, and at quantum physics, relativity and

    Although it has been argued that psychiatrists entered the modern era with the introduction of shock therapies and lobotomy in the 1930s and antipsychotic drugs in the 1950s, practicing psychiatrists of the 1910s and 1920s did not feel they were in the dark ages of therapeutics. These early twentieth-century psychiatrists had a variety of somatic remedies at their disposal. For example, they had a plethora of sedatives and hypnotic agents from which to choose, although these drugs too often produced troublesome side effects, and, from the point of view of these physicians, too closely resembled physical restraint in their effects on the patient. As we saw, physical restraint had a sullied reputation, psychiatrists believing it, at best, to be a necessary evil and not part of a therapeutic regimen. This did not mean psychiatrists felt helpless in treating insanity for they firmly believed that, unlike drugs and physical restraint, hydrotherapy acted therapeutically. Our examination of every-day treatment practices at Stockton and Patton state hospitals revealed that physicians found hydrotherapy to be a useful remedy on nearly all patients irrespective of diagnosis. The Agnews' investigation allowed us to examine the basic assumptions underpinning early twentieth-century therapeutics, and two major conclusions can be gleaned from this examination. First, how doctors perceive disease is inseparably linked to how they treat disease. In the case of hydrotherapy, physicians believed it effectively controlled their patients' behavior. To assert that it had therapeutic value and to differentiate it from mechanical restraint, however physicians transformed how they saw disease and therapy such that wrapping and bathing the "excited" and "frenzied" patients were therapeutic. Rather than seeing disruptive behavior as simply something in need of physical restraint, hydrotherapy allowed physicians to see these behaviors as the essence of disease and the primary object of their

    The National Observatory of Brazil was created in 1827. It was initially focused on the practical teaching of Astronomy to the students of military and naval academies. Since the mid-nineteenth century to the early twentieth century it was installed over the ruins of a Jesuit church located in the center of Rio de Janeiro, capital of the Brazilian Empire.Due to the constant complaints of its successive directors, the search for a new site to house the Observatory began in 1911. The new headquarters of the institution were located on the hill of São Januário, a little further but still around the city center of Rio de Janeiro. Its inauguration took place in 1921.The main building of the new Observatory was based on one of the Brazilian pavilions of the Turin Exhibition of 1911, and its architecture can be characterized as eclectic. The pavilions intended to house the many telescopes were scattered in a large wooded area. Since 1985 all these facilities are protected by the Federal government, as a consequence of the same initiative that gave birth to the Museum of Astronomy and Related Sciences, which has the custody also of the Observatory’s former instruments, furniture, and documents.Although built in the early twentieth century the National Observatory new facilities reveal astronomical practices typical of the previous century. One of its most important activities was the determination of the legal time, a task that justifies its location in the urban environment. It was also responsible for the organization of expeditions destined to determine the geographical positions of railroads and the borders of Brazil. For this reason, the Museum of Astronomy has currently more than 3,000 portable instruments. Moreover, these instruments belong to the domain of Astronomy, but also to Geodesy, Meteorology, Electricity. Due to the creation of the Museum of Astronomy, this rich collection is now open to public visitation, and has become the object of scholarly

    The connection between the development of anesthesiology and pain therapy in the twentieth century is close. The optimistic idea to overcome pain by using general anesthesia derives from the nineteenth century. Treatment of nonsurgical pain remained in the background for a long time and innovations in pain medicine did not improve the insufficient care for patients with postoperative pain. Therapy of chronic pain was mainly surgical and the extreme of this surgical approach was psychosurgery. In the years following World War II leucotomy and lobotomy were established as methods to separate the psychological processing of pain from the experience of pain. Meanwhile, the French "pain surgeon" René Leriche elaborated a theory of pain where chronic pain was no longer seen as a symptom but as a "douleur-maladie", a pain disease. His theory was considered on various occasions but did not gain acceptance before the 1950s. Research in anesthesiology, such as that conducted by the American scientist Henry Beecher separated psyche and physiology with respect to pathological pain. This was contrasted by the approach of clinical anesthesia to pain therapy, which was based on regional anesthesia. The first "pain clinics" were "nerve block clinics". John Bonica, a regional anesthesiologist, extended the framework of pain therapy by introducing multidisciplinary teamwork into the therapy of chronic pain. From today's viewpoint his 1953 monograph The Management of Chronic Pain is a milestone in the development of modern pain therapy. However, Bonica's work did not attain major importance until 1960 when he was appointed to a newly established chair. Gradually, chronic pain was recognized as an independent illness and differentiated as such from acute pain. In 1965 the gate control theory by Melzack and Wall offered a possible explanation for the mechanisms of chronic pain. By the end of the 1970s the spectrum was extended to the biopsychosocial approach which was foremost

    This work proposes a daily high-resolution probabilistic reconstruction of precipitation and temperature fields in France over the 1871-2012 period built on the NOAA Twentieth Century global extended atmospheric reanalysis (20CR). The objective is to fill in the spatial and temporal data gaps in surface observations in order to improve our knowledge on the local-scale climate variability from the late nineteenth century onwards. The SANDHY (Stepwise ANalogue Downscaling method for HYdrology) statistical downscaling method, initially developed for quantitative precipitation forecast, is used here to bridge the scale gap between large-scale 20CR predictors and local-scale predictands from the Safran high-resolution near-surface reanalysis, available from 1958 onwards only. SANDHY provides a daily ensemble of 125 analogue dates over the 1871-2012 period for 608 climatically homogeneous zones paving France. Large precipitation biases in intermediary seasons are shown to occur in regions with high seasonal asymmetry like the Mediterranean. Moreover, winter and summer temperatures are respectively over- and under-estimated over the whole of France. Two analogue subselection methods are therefore developed with the aim of keeping the structure of the SANDHY method unchanged while reducing those seasonal biases. The calendar selection keeps the analogues closest to the target calendar day. The stepwise selection applies two new analogy steps based on similarity of the sea surface temperature (SST) and the large-scale 2 m temperature (T). Comparisons to the Safran reanalysis over 1959-2007 and to homogenized series over the whole twentieth century show that biases in the interannual cycle of precipitation and temperature are reduced with both methods. The stepwise subselection moreover leads to a large improvement of interannual correlation and reduction of errors in seasonal temperature time series. When the calendar subselection is an easily applicable method suitable in

    This chapter takes a brief look at the benefits of commissioning and describes a vision of the future where most of the objectives of commissioning will be accomplished automatically by capabilities built into the building systems themselves. Commissioning will become an activity that is performed continuously rather than periodically, and only repairs requiring replacement or overhaul of equipment will require manual intervention. This chapter then identifies some of the technologies that will be needed to realize this vision and ends with a call for all involved in the enterprise of building commissioning and automation to embrace and dedicate themselves to a future of automated commissioning.

  2. VLT Commissioning Data Now Publicly Available

    data are "raw" in the sense that they come directly from the instrument. The original files are recorded in standard FITS-format and in order to save space, they have been compressed by a factor of about 2. Before they can be used, they must therefore first be decompressed and subjected to image processing, e.g. with the ESO MIDAS system , available on a special MIDAS CD-ROM from ESO. The above image of a well-known spiral galaxy, Messier 83 , was prepared by superposing three CCD frames from this data release that are now available in the archive. This galaxy is located in the southern constellation Hydra (The Water-Snake) and is also known as NGC 5236 ; the distance is about 15 million light-years. The spiral structure resembles that of the Milky Way Galaxy in which we live, but Messier 83 also possesses a bar-like structure at the centre. Corresponding frames of many other interesting objects are included among the data now released. A small part of these have served to produce some of the VLT Astronomical Images that have been released at the ESO Outreach website during the past year. Current VLT observations Observations continue with the first two VLT Unit Telescopes, ANTU and KUEYEN ; the latter is still in the Commissioning Phase with the UVES and FORS2 instruments until it will be made available to the astronomers on April 1, 2000. The current VLT data production rate is about 2200 files/week, corresponding to about 10 Gigabytes or 16 CD-ROMs. Efficient data handling procedures developed by ESO ensure a rapid and secure transfer from the telescopes at the Paranal Observatory to the data archive at the Garching Headquarters, and from here to the receiving astronomers. A description of the main features of this "VLT Data Flow System" is available in PR 10/99. The amount of data will increase as more instruments enter into operation and will ultimately reach about 40,000 Gigabytes/year.

    Currently, houses do not perform optimally or even as many codes and forecasts predict, largely because they are field assembled and there is no consistent process to identify deficiencies or to correct them. Solving this problem requires field performance evaluations using appropriate and agreed upon procedures in the form of a new process called residential commissioning. The purpose of this project is to develop and document these procedures and to demonstrate the value that applying them could provide in both new and existing California houses. This project has four specific objectives: to develop metrics and diagnostics for assessing house performance, to provide information on the potential benefits of commissioning using a whole-house approach, to develop programmatic guidelines for commissioning, and to conduct outreach efforts to transfer project results to industry stakeholders. The primary outcomes from this project are the development of residential commissioning guidelines and the analytical confirmation that there are significant potential benefits associated with commissioning California houses, particularly existing ones. In addition, we have made substantial advances in understanding the accuracy and usability of diagnostics for commissioning houses. In some cases, we have been able to work with equipment manufacturers to improve these aspects of their diagnostic tools. These outcomes provide a solid foundation on which to build a residential commissioning program in California. We expect that a concerted effort will be necessary to integrate such a program with existing building industry efforts and to demonstrate its use in the field.

    2002-09-01

    This essay uses an approach borrowed from environmental history to investigate the interaction of science and nature in a late twentieth-century controversy. This debate, over the proper response to fire ants that had been imported into the American South accidentally and then spread across the region, pitted Rachel Carson and loosely federated groups of conservationists, scientists, and citizens against the U.S. Department of Agriculture. The analysis falls into three sections: an examination of the natural history of the ants; an examination of the views of the competing factions; and an examination of how those views, transformed into action, affected the natural world. Both sides saw the ants in terms of a constellation of beliefs about the relationship between nature, science, and democracy. As various ideas were put into play, they interacted with the natural history of the insects in unexpected ways--and with consequences for the cultural authority of the antagonists. Combining insights from the history of science and environmental history helps explain how scientists gain and lose cultural authority and, more fundamentally, allows for an examination of how nature can be integrated into the history of science.

    Concerned with the study of viruses and the diseases they cause, virology is now a well-established scientific discipline. Whereas aspects of its history from the late nineteenth to the mid-twentieth century have often been recounted through a number of detailed case studies, few general discussions of the historiography of virology have been offered. Looking at the ways in which the history of virology has been told, this article examines a number of debates among scientists and historians of biology and show how they are based on a different understanding of notions such as "discipline", of processes such as "scientific discovery" as well as on distinct views about what the history of science is and how it should be written (the opposition between "longue durée" and "micro-history" or between history of "concepts" versus "experimental methods"). The analysis provided here also suggests that a richer historiography of virology will require looking at the variations over time of the relations between conceptual, technological, and institutional factors that fostered its development at the intersection of several other scientific fields in the life sciences.

  7. Statistically derived contributions of diverse human influences to twentieth-century temperature changes

    The warming of the climate system is unequivocal as evidenced by an increase in global temperatures by 0.8°C over the past century. However, the attribution of the observed warming to human activities remains less clear, particularly because of the apparent slow-down in warming since the late 1990s. Here we analyse radiative forcing and temperature time series with state-of-the-art statistical methods to address this question without climate model simulations. We show that long-term trends in total radiative forcing and temperatures have largely been determined by atmospheric greenhouse gas concentrations, and modulated by other radiative factors. We identify a pronounced increase in the growth rates of both temperatures and radiative forcing around 1960, which marks the onset of sustained global warming. Our analyses also reveal a contribution of human interventions to two periods when global warming slowed down. Our statistical analysis suggests that the reduction in the emissions of ozone-depleting substances under the Montreal Protocol, as well as a reduction in methane emissions, contributed to the lower rate of warming since the 1990s. Furthermore, we identify a contribution from the two world wars and the Great Depression to the documented cooling in the mid-twentieth century, through lower carbon dioxide emissions. We conclude that reductions in greenhouse gas emissions are effective in slowing the rate of warming in the short term.

    What is the association between macroeconomic conditions and public perceptions of social class? Applying a novel approach based on the Google Books N-gram corpus, this study addresses the relationship between public concerns about social class and economic conditions throughout the twentieth century. The usage of class-related words/phrases, or "literary references to class," in American English-language books is related to US economic performance and income inequality. The findings of this study demonstrate that economic conditions play a significant role in literary references to class throughout the century, whereas income inequality does not. Similar results are obtained from further analyses using alternative measures of class concerns as well as different corpora of English Fiction and the New York Times. We add to the social class literature by showing that the long-term temporal dynamics of an economy can be exhibited by aggregate class concerns. The application of massive culture-wide content analysis using data of unprecedented size also represents a contribution to the literature. PMID:27480370

    2007-12-01

    Prompted by recent recognitions of the omnipresence of horizontal gene transfer among microbial species and the associated emphasis on exchange, rather than isolation, as the driving force of evolution, this essay will reflect on hybridization as one of the central concerns of nineteenth-century biology. I will argue that an emphasis on horizontal exchange was already endorsed by 'biology' when it came into being around 1800 and was brought to full fruition with the emergence of genetics in 1900. The true revolution in nineteenth-century life sciences, I maintain, consisted in a fundamental shift in ontology, which eroded the boundaries between individual and species, and allowed biologists to move up and down the scale of organic complexity. Life became a property extending both 'downwards', to the parts that organisms were composed of, as well as 'upwards', to the collective entities constituted by the relations of exchange and interaction that organisms engage in to reproduce. This mode of thinking was crystallized by Gregor Mendel and consolidated in the late nineteenth-century conjunction of biochemistry, microbiology and breeding in agro-industrial settings. This conjunction and its implications are especially exemplified by Wilhelm Johannsen's and Martinus Beijerinck's work on pure lines and cultures. An understanding of the subsequent constraints imposed by the evolutionary synthesis of the twentieth century on models of genetic systems may require us to rethink the history of biology and displace Darwin's theory of natural selection from that history's centre.

    At the beginning of the twentieth century, an anaesthetist could choose between nitrous oxide, chloroform, and ether (diethyl ether) for the induction of painrelieving unconsciousness. By the end of century, the choice was between a small number of fluorinated aliphatic ethers such as Enflurane, Desflurane, and Sevoflurane, and (in some jurisdictions) the rare gas, xenon. Between these endpoints researchers had identified a surprisingly broad range of hydrocarbons, noble gases, organohalogens, and aliphatic ethers that possessed anaesthetic properties. None was entirely satisfactory, but clinicians at various times and in various places employed substances in each of these categories. Behind the search for new anaesthetic gases was a theory of action (Meyer- Overton theory) that was known to be inadequate, but as no alternative was strong enough to displace it the search continued on purely empirical grounds, while lip-service was paid to the theory. By the time a theory couched in more modern terms was proposed, a suite of modern anaesthetic gases was in place, and there have been no attempts to use that theory to drive a new search.

    2015-04-01

    Focusing on China in the second half of the twentieth century, we examine the relative role of aerosols and prescribed, observation based sea surface temperatures (SSTs) for the evolution of surface solar radiation (SSR), surface air temperature (SAT), and precipitation in ensembles of transient (1870 - 2005) sensitivity experiments with the global climate model ECHAM5-HAM. Observations and simulations with transient SSTs and aerosol emissions agree reasonably well in eastern China in terms of SSR dimming (-6 +/- 2 W/m2/decade, 1960 - 2000), statistically non-significant JJA SAT trend (1950 - 2000), and drying in JJA from 1950 to 1990 (-2.5% to -3.5% per decade, essentially via reduction of convective precipitation). Other major observed features are not reproduce by the model, e.g. precipitation increase in the 1990s in the Yangtze valley, the strong warming in winter in northern parts of China and Mongolia, or SSR dimming in western China. For the model results, SO2 emissions are more relevant than emissions of black and organic carbon. Aerosol effects are less pronounced at higher model resolution. Transient SSTs are found to be crucial for decadal scale SAT variability over land, especially the strong warming in the 1990s, and, via SST forced reduction of cloud cover, for the ceasing of SSR dimming around the year 2000. Unforced cloud variability leads to relevant scatter (up to +/- 2 W/m2/decade) of modeled SSR trends at individual observation sites.

    After the passing of the 1902 Midwives Act, a growing proportion of women were delivered by trained and supervised midwives. Standards of midwifery should therefore have improved over the first three decades of the twentieth century, yet nationally this was not reflected in the main outcome measures (stillbirths, early neonatal mortality and maternal death). This paper shows that there was a difference in the risks associated with delivery by the different attendants, with qualified midwives having the best outcome, then bona-fide (untrained) midwives and lastly doctors, even when account is taken of the fact that doctors were called in cases of medical need and may have been booked where a problematic delivery was expected. The paper argues that the lack of improvement in outcome measures could be consistent with improving standards of care among both trained and bona-fide midwives, because increased attention to the rules stipulating when midwives called for medical help meant that a doctor was called into an increasing number of deliveries (including less complicated ones), raising the chance of unnecessary and dangerous interventions.

    'Congenital phimosis' was one of a number of pseudo-pathologies that entered mainstream medicine in the nineteenth century. In the twentieth century Truby King, Henry Jellett, and Eric Corkill advocated premature foreskin retraction as the first intervention to manage 'congenital phimosis'. If that failed they recommended circumcision, although eventually it became more expedient to use circumcision exclusively. The nineteenth-century justification for such interventions was to prevent masturbation, but by the middle of the twentieth century this was replaced by prevention of infections. Gairdner's landmark paper of 1949 turned New Zealand doctors away from 'congenital phimosis' and non-therapeutic circumcision, although some doctors and persisting family traditions maintained both interventions until the end of the century.

    δ13C values for freshwater aquatic plant matter varies from −11 to −50‰ and is not a clear indicator of photosynthetic pathway as in terrestrial plants. Several factors affect δ13C of aquatic plant matter. These include: (1) The δ13C signature of the source carbon has been observed to range from +1‰ for HCO3− derived from limestone to −30‰ for CO2 derived from respiration. (2) Some plants assimilate HCO3−, which is –7 to –11‰ less negative than CO2. (3) C3, C4, and CAM photosynthetic pathways are present in aquatic plants. (4) Diffusional resistances are orders of magnitude greater in the aquatic environment than in the aerial environment. The greater viscosity of water acts to reduce mixing of the carbon pool in the boundary layer with that of the bulk solution. In effect, many aquatic plants draw from a finite carbon pool, and as in terrestrial plants growing in a closed system, biochemical discrimination is reduced. In standing water, this factor results in most aquatic plants having a δ13C value similar to the source carbon. Using Farquhar's equation and other physiological data, it is possible to use δ13C values to evaluate various parameters affecting photosynthesis, such as limitations imposed by CO2 diffusion and carbon source.

    The Antarctic seasonal station-based pressure reconstructions evaluated in our companion paper are evaluated here to provide additional knowledge on Antarctic pressure variability during the twentieth century. In the period from 1905 to 1956, we find that the Hadley Centre gridded sea level pressure data set compared the best with our reconstructions, perhaps due to similar methods to estimate pressure without direct observations. The primary focus on the twentieth century Antarctic pressure variability was in summer and winter, as these were the seasons with the highest reconstruction skill. In summer, there is considerable interannual variability that was spatially uniform across all of Antarctica. Notable high pressure anomalies were found in the summers of 1911/1912 and 1925/1926; both summers correspond to negative phases of the Southern Annular Mode as well as El Niño events in the tropical Pacific. In addition, negative summer pressure trends during the last ~40 years across all of Antarctica are unique in the context of 30 year trends throughout the entire twentieth century, suggesting a strong component of anthropogenic forcing on the recent summer trends. In contrast, mean winter pressure is less variable from year to year during the early twentieth century, and there is less similarity between the pressure variations along the Antarctic Peninsula compared to the rest of the continent. No significant pressure trends were found consistently across all Antarctica (although some significant regional trends can be identified), and low-frequency, multidecadal-scale variability appears to dominate the historical pressure variations in this season.

    This paper provides brief profiles of four doctors of medicine who wrote books for optometrists and who were faculty members in, and/or directors of, optometry schools in the early twentieth century. Those studied were Thomas G. Atkinson (1870-1946), Marshall B. Ketchum (1856-1937), Joseph I. Pascal (1890-1955), and Clarence W. Talbot (1883-1958). The content of the books they wrote is also discussed.

  19. Twentieth-century global-mean sea level rise: Is the whole greater than the sum of the parts?

    Confidence in projections of global-mean sea level rise (GMSLR) depends on an ability to account for GMSLR during the twentieth century. There are contributions from ocean thermal expansion, mass loss from glaciers and ice sheets, groundwater extraction, and reservoir impoundment. Progress has been made toward solving the “enigma” of twentieth-century GMSLR, which is that the observed GMSLR has previously been found to exceed the sum of estimated contributions, especially for the earlier decades. The authors propose the following: thermal expansion simulated by climate models may previously have been underestimated because of their not including volcanic forcing in their control state; the rate of glacier mass loss was larger than previously estimated and was not smaller in the first half than in the second half of the century; the Greenland ice sheet could have made a positive contribution throughout the century; and groundwater depletion and reservoir impoundment, which are of opposite sign, may have been approximately equal in magnitude. It is possible to reconstruct the time series of GMSLR from the quantified contributions, apart from a constant residual term, which is small enough to be explained as a long-term contribution from the Antarctic ice sheet. The reconstructions account for the observation that the rate of GMSLR was not much larger during the last 50 years than during the twentieth century as a whole, despite the increasing anthropogenic forcing. Semiempirical methods for projecting GMSLR depend on the existence of a relationship between global climate change and the rate of GMSLR, but the implication of the authors' closure of the budget is that such a relationship is weak or absent during the twentieth century.

    The Linac Coherent Light Source is a SASE x-ray free-electron laser (FEL) project presently under construction at SLAC [J. Arthur , SLAC-R-593, 2002.]. The injector section, from drive laser and rf photocathode gun through first bunch compressor chicane, was installed in the fall of 2006. The initial system commissioning with an electron beam was completed in August of 2007, with the goal of a 1.2-micron emittance in a 1-nC bunch demonstrated. The second phase of commissioning, including second bunch compressor and full linac, is planned for 2008, with FEL commissioning in 2009. We report experimental results and experience gained in the first phase of commissioning, including the photocathode drive laser, rf gun, photocathode, S-band and X-band rf systems, first bunch compressor, and the various beam diagnostics.

  15. Building commissioning: The key to quality assurance

    SciTech Connect

    1998-05-01

    This Guide is written to aid building owners and retrofit project managers currently participating in the Rebuild America program. The Guide provides information on implementing building commissioning projects that will optimize the results of existing building equipment improvements and retrofits projects. It should be used in coordination with Rebuild America`s Community Partnership Handbook. The Handbook describes, in detail, eight important steps necessary for planning and carrying out a community-wide energy-efficiency program. In step number 7 of the Handbook, commissioning is shown to be an integral aspect of implementing a building retrofit. The commissioning process ensures that a facility is safe, efficient, comfortable, and conducive to the presumed activities for which it was constructed. Rebuild America strongly encourages its partners to incorporate commissioning into their retrofit projects. By verifying the correct installation, functioning, operation, and maintenance of equipment, the commissioning process ensures that efficiency measures will continue to deliver benefits over the long term. Although commissioning can take place after the equipment has been installed, it is more effective when it takes place over the entire equipment installation process.

  6. Twentieth century constraints on sea level change and earthquake deformation at Macquarie Island

    Through the combination of rare historical sea level observations collected during Sir Douglas Mawson's 1911-1914 Australasian Antarctic Expedition (AAE), together with modern sea level data, space geodetic estimates of crustal displacement and modelling of coseismic and post-seismic earthquake deformation, we present a contemporary analysis to constrain sea level and land level change over the twentieth century at Macquarie Island (54°30'S, 158°57'E). We combine 9 months of 1912-1913 sea level data with intermediate observations in 1969-1971, 1982 and 1998-2007 to estimate sea level rise relative to the land at +4.8 +/- 0.6 mm yr-1. Combined with estimates of global mean sea level rise, this value supports the geologically surprising notion of land subsidence, conflicting with longer term geological evidence that suggests uplift at ~0.8 mm yr-1 over the last 400-300 Kyr. We investigate the current tectonic evolution of the Island through analysis of Global Positioning System (GPS) solutions that utilize data over the period 2000-2009. Importantly, this provides an opportunity to refine the source parameters of the Mw ~8.0 great earthquake of 2004 December 23 using estimates of coseismic displacements at regional GPS sites. We use the estimated earthquake source and GPS observations of four years of post-seismic deformation at Macquarie Island to infer the rheology of the oceanic upper mantle. We find that an asthenosphere bounded by stronger material above and below is required to produce the observed post-seismic deformation, particularly in the vertical component. Assuming a Maxwell rheology, the best fit is given by an asthenospheric viscosity of 3×1019 Pa s. The inferred rheology determined from the 2004 earthquake is used to model long period post-seismic deformation from Mw ~8.0 earthquakes of 1989 and 1924. The 1924 earthquake is the closest of the three great earthquakes to Macquarie Island, and our modelling suggests that the majority of the vertical

  7. [Pain and anesthesiology : aspects of the development of modern pain therapy in the twentieth century].

    The connection between the development of anesthesiology and pain therapy in the twentieth century is close. The optimistic idea to overcome pain by using general anesthesia derives from the nineteenth century. Treatment of nonsurgical pain remained in the background for a long time and innovations in pain medicine did not improve the insufficient care for patients with postoperative pain. Therapy of chronic pain was mainly surgical and the extreme of this surgical approach was psychosurgery. In the years following World War II leucotomy and lobotomy were established as methods to separate the psychological processing of pain from the experience of pain. Meanwhile, the French "pain surgeon" René Leriche elaborated a theory of pain where chronic pain was no longer seen as a symptom but as a "douleur-maladie", a pain disease. His theory was considered on various occasions but did not gain acceptance before the 1950s. Research in anesthesiology, such as that conducted by the American scientist Henry Beecher separated psyche and physiology with respect to pathological pain. This was contrasted by the approach of clinical anesthesia to pain therapy, which was based on regional anesthesia. The first "pain clinics" were "nerve block clinics". John Bonica, a regional anesthesiologist, extended the framework of pain therapy by introducing multidisciplinary teamwork into the therapy of chronic pain. From today's viewpoint his 1953 monograph The Management of Chronic Pain is a milestone in the development of modern pain therapy. However, Bonica's work did not attain major importance until 1960 when he was appointed to a newly established chair. Gradually, chronic pain was recognized as an independent illness and differentiated as such from acute pain. In 1965 the gate control theory by Melzack and Wall offered a possible explanation for the mechanisms of chronic pain. By the end of the 1970s the spectrum was extended to the biopsychosocial approach which was foremost

  8. Urania in the Marketplace: Astronomical Imagery in Early Twentieth-Century Advertizing

    NASA Astrophysics Data System (ADS)

    Rumstay, Kenneth S.

    2010-01-01

    The pages of popular magazines such as Sky and Telescope and Astronomy are filled with advertisements for telescopes and other equipment. However, during the past century astronomical imagery has been widely used to promote distinctly non-astronomical products and services. One of the earliest and most famous examples is the 1893 Chicago newspaper advertisement for Kirk's Soap, which was inspired by the opening of the Yerkes Observatory. A survey of popular magazines published in America during the first half of the twentieth century suggests that these advertisements fall into four categories: 1) Astronomy is universally regarded as an exact and precise science. Manufacturers of mechanical devices may employ images of telescopes or astronomers at work to suggest that their products meet these same standards of quality. This was primarily the case with makers of automobiles and automotive products, although the Longines Watch Company ran an extensive series of ads featuring observatories. 2) The heavens induce a sense of wonder in most people, and advertisers may locate their products in an a celestial setting to give them an otherworldly flavor. 3) Astronomical observatories themselves are viewed as exotic settings, and have provided backgrounds for automotive and travel ads. They may also appear in advertisements for products used in their construction. 4) Finally, newsworthy astronomical events will inspire advertisers to associate their products with that event, in order to capitalize upon the publicity. This was particularly true in the case of the 1910 passage of Halley's Comet and the 1948 opening of the 200-inch Hale telescope at Mt. Palomar. Examples of magazine advertisements from each category are presented for comparison. This work was supported by a faculty development grant from Valdosta State University.

    The hydroxyl radical, OH, is the dominant sink for the majority of trace gases in the troposphere. Thus, it plays a major role in controlling atmospheric chemical composition. However despite this importance there remains much uncertainty as to whether concentrations of OH have changed in the background atmosphere in recent decades. It has previously been reported that recent levels of OH in the troposphere (1997-2008) are well buffered against changes in atmospheric composition (Montzka et al., 2011). We present two independent records that suggest that there was a significant increase in concentrations of the OH radical in the northern hemisphere during the last two decades of the twentieth century. Measurements from Greenland firn air of the changing ratios of n-butane, iso-butane, n-pentane and iso-pentane were compared using a photochemical clock method. Using these changing ratios we calculate an increase in the chemical processing of the air (i.e. [OH].t) between 1980 and 2000. Assuming t to be constant this provides a semi-quantitative historic record of OH concentrations. Furthermore, measurements of three alkyl nitrates (also from Greenland firn air), secondary oxidation products of the alkanes, suggest an increase in the [NO]/[HO2] ratio in the background atmosphere. This could be indicative of increasing NOx concentrations during this period, which would be consistent with increasing [OH]. These two records are further corroborated by comparison with the long term trend in increasing ozone mixing ratios from background European sites. Knowledge of historic changes to the oxidative capacity of the atmosphere is fundamental to understanding the atmospheric records of trace gases and to determining historic trace gas emissions using top-down approaches. The results presented here have profound implications for our understanding of atmospheric composition in the past, the present and for predicting the future evolution of the atmosphere.

  10. Metal Construction Toys of the Early Twentieth Century: Their Astronomical Applications

    NASA Astrophysics Data System (ADS)

    Rumstay, K. S.

    2004-12-01

    During the early twentieth century several toy manufacturers around the globe introduced construction toys in the form of sets of metal parts which could be assembled into a variety of models. The two most successful were the Erector Set, introduced in the United States by A.C. Gilbert in 1913, and the Meccano Set, patented in 1901 in England by Frank Hornby. Whereas the Erector Set never developed beyond being a child's toy, Hornby envisioned his Meccano system as providing a way to teach principles of mechanical engineering to young schoolboys. Indeed, his sets were first marketed under the name "Mechanics Made Easy", and were endorsed by Dr. H.S. Hele-Shaw, Head of the Engineering Department at Liverpool University. Popularity of the new Meccano sets spread throughout the world, spawning the formation of numerous amateur societies composed of adolescent boys and an increasing number of adult hobbyists. The variety of parts increased during the first third of the century, and increasingly sophisticated models were constructed and exhibited in competitive events. Among these were several clocks of remarkable accuracy, and at least one equatorial mounting for a small astronomical telescope. At the same time, many university science and engineering departments found these interchangeable metal parts invaluable in the construction of experimental apparatus. In 1934 a small-scale replica of Vannevar Bush's Differential Analyzer was constructed at the University of Manchester, and used for many years to perform mathematical computations. The introduction in 1928 of a flanged ring with 73 (a sub-multiple of 365) teeth allowed for construction of accurate orreries and astronomical clocks. The most remarkable of these was the Astronomical Clock constructed in the period 1924-1932 by M. Alexandre Rahm of Paris.

  11. Assessing the impact of vertical land motion on twentieth century global mean sea level estimates

    Near-global and continuous measurements from satellite altimetry have provided accurate estimates of global mean sea level in the past two decades. Extending these estimates further into the past is a challenge using the historical tide gauge records. Not only is sampling nonuniform in both space and time, but tide gauges are also affected by vertical land motion (VLM) that creates a relative sea level change not representative of ocean variability. To allow for comparisons to the satellite altimetry estimated global mean sea level (GMSL), typically the tide gauges are corrected using glacial isostatic adjustment (GIA) models. This approach, however, does not correct other sources of VLM that remain in the tide gauge record. Here we compare Global Positioning System (GPS) VLM estimates at the tide gauge locations to VLM estimates from GIA models, and assess the influence of non-GIA-related VLM on GMSL estimates. We find that the tide gauges, on average, are experiencing positive VLM (i.e., uplift) after removing the known effect of GIA, resulting in an increase of 0.24 ± 0.08 mm yr-1 in GMSL trend estimates from 1900 to present when using GPS-based corrections. While this result is likely dependent on the subset of tide gauges used and the actual corrections used, it does suggest that non-GIA VLM plays a significant role in twentieth century estimates of GMSL. Given the relatively short GPS records used to obtain these VLM estimates, we also estimate the uncertainty in the GMSL trend that results from limited knowledge of non-GIA-related VLM.

  12. SUMMARY REPORT OF THE DOE DIRECT LIQUEFACTION PROCESS DEVELOPMENT CAMPAIGN OF THE LATE TWENTIETH CENTURY

    Following the petroleum price and supply disruptions of 1973, the U.S. government began a substantial program to fund the development of alternative fuels. Direct coal liquefaction was one of the potential routes to alternative fuels. The direct coal liquefaction program was funded at substantial levels through 1982, and at much lower levels thereafter. Those processes that were of most interest during this period were designed to produce primarily distillate fuels. By 1999, U.S. government funding for the development of direct coal liquefaction ended. Now that the end of this campaign has arrived, it is appropriate to summarize the process learnings derived from it. This report is a summary of the process learnings derived from the DOE direct coal liquefaction process development campaign of the late twentieth century. The report concentrates on those process development programs that were designed to produce primarily distillate fuels and were largely funded by DOE and its predecessors in response to the petroleum supply and price disruptions of the 1970s. The report is structured as chapters written by different authors on most of the major individual DOE-funded process development programs. The focus of the report is process learnings, as opposed to, say, fundamental coal liquefaction science or equipment design. As detailed in the overview (Chapter 2), DOE's direct coal liquefaction campaign made substantial progress in improving the process yields and the quality of the distillate product. Much of the progress was made after termination by 1983 of the major demonstration programs of the ''first generation'' (SRC-II, H-Coal, EDS) processes.

  13. Aerosols implicated as a prime driver of twentieth-century North Atlantic climate variability.

    Systematic climate shifts have been linked to multidecadal variability in observed sea surface temperatures in the North Atlantic Ocean. These links are extensive, influencing a range of climate processes such as hurricane activity and African Sahel and Amazonian droughts. The variability is distinct from historical global-mean temperature changes and is commonly attributed to natural ocean oscillations. A number of studies have provided evidence that aerosols can influence long-term changes in sea surface temperatures, but climate models have so far failed to reproduce these interactions and the role of aerosols in decadal variability remains unclear. Here we use a state-of-the-art Earth system climate model to show that aerosol emissions and periods of volcanic activity explain 76 per cent of the simulated multidecadal variance in detrended 1860-2005 North Atlantic sea surface temperatures. After 1950, simulated variability is within observational estimates; our estimates for 1910-1940 capture twice the warming of previous generation models but do not explain the entire observed trend. Other processes, such as ocean circulation, may also have contributed to variability in the early twentieth century. Mechanistically, we find that inclusion of aerosol-cloud microphysical effects, which were included in few previous multimodel ensembles, dominates the magnitude (80 per cent) and the spatial pattern of the total surface aerosol forcing in the North Atlantic. Our findings suggest that anthropogenic aerosol emissions influenced a range of societally important historical climate events such as peaks in hurricane activity and Sahel drought. Decadal-scale model predictions of regional Atlantic climate will probably be improved by incorporating aerosol-cloud microphysical interactions and estimates of future concentrations of aerosols, emissions of which are directly addressable by policy actions.

  17. A Chronology of Annual-Mean Effective Radii of Stratospheric Aerosols from Volcanic Eruptions During the Twentieth Century as Derived From Ground-based Spectral Extinction Measurements

    NASA Technical Reports Server (NTRS)

    Stratospheric extinction can be derived from ground-based spectral photometric observations of the Sun and other stars (as well as from satellite and aircraft measurements, available since 1979), and is found to increase after large volcanic eruptions. This increased extinction shows a characteristic wavelength dependence that gives information about the chemical composition and the effective (or area weighted mean) radius of the particles responsible for it. Known to be tiny aerosols constituted of sulfuric acid in a water solution, the stratospheric particles at midlatitudes exhibit a remarkable uniformity of their column-averaged effective radii r(sub eff) in the first few months after the eruption. Considering the seven largest eruptions of the twentieth century, r(sub eff) at this phase of peak aerosol abundance is approx. 0.3 micrometers in all cases. A year later, r(sub eff) either has remained about the same size (almost certainly in the case of the Katmai eruption of 1912) or has increased to approx. 0.5 micrometers (definitely so for the Pinatubo eruption of 1991). The reasons for this divergence in aerosol growth are unknown.

    Commission 45 is solidly anchored in the beginnings of the IAU. It evolved out of Commission 29, which was one of the original commissions and whose title and emphasis was the Spectral Classification of Stars (Transactions of the IAU, Volume I, 1922). C29 was formed with W.S. Adams (Pasadena) as president. Its first members were Miss Cannon, R.H. Curtiss, A. Fowler, A. de Gramont, M. Hamy, H.F. Newall, J.S. Plaskett, H.N. Russell, all very much part of the history of stellar spectroscopy. In the 1922 Transactions report it was recognized the Harvard System of spectral classification ``has already been adopted by international agreement. . .''

    2000-07-01

    The Very Large Telescope Interferometer (VLTI) is a complex system, made of a large number of separated elements. To prepare an early successful operation, it will require a period of extensive testing and verification to ensure that the many devices involved work properly together, and can produce meaningful data. This paper describes the concept chosen for the VLTI commissioning instrument, LEONARDO da VINCI, and details its functionalities. It is a fiber based two-way beam combiner, associated with an artificial star and an alignment verification unit. The technical commissioning of the VLTI is foreseen as a stepwise process: fringes will first be obtained with the commissioning instrument in an autonomous mode (no other parts of the VLTI involved); then the VLTI telescopes and optical trains will be tested in autocollimation; finally fringes will be observed on the sky.

    Objectives To describe the incidences and causes of occupational police deaths in New York City in the United States and Greater London in the United Kingdom during the twentieth century. To assess the relation between overall societal violence and violence directed toward police officers in these metropolitan areas. Design and setting Ecological study of New York and London from 1900 through 1999. Main outcome measures Intentional and unintentional occupational police mortality rates for New York and London were estimated for each decade. The general population homicide rates of both New York and London were assessed for their correlation with their respective intentional occupational police mortality rates. Results During the 20th century, 585 police officers in New York and 160 police officers in London died while participating in law enforcement activities. New York had markedly greater intentional police mortality rates compared to London throughout most of the 20th century, but these differences decreased significantly by the end of the century. Intentional gunshot wounds comprised 290 police deaths in New York, but only 14 police deaths in London. In New York, gun shot wounds (both intentional and unintentional) accounted for more occupational police deaths (51.6%) than did all other injury mechanisms combined. In London, motor vehicle collision was the most common cause (47.5%) of occupational police death. There were no apparent correlations between the general population homicide rates and intentional police mortality rates in either New York (r2 = 0.05, 95% CI −0.77 to 0.81) or London (r2 = 0.34, 95% CI −0.61 to 0.89). Conclusions During the 20th century, both intentional and unintentional occupational police mortality rates were significantly greater in New York compared to London. These differences are likely from several socioeconomic, cultural, and occupational factors. The declines in police deaths in New York during the latter part of

  9. Changing Trends and Variance in Eastern Equatorial Pacific Sea Surface Temperatures over the Twentieth Century

    NASA Astrophysics Data System (ADS)

    2015-12-01

    Global climate models and instrumental datasets often disagree regarding sea surface temperature (SST) trends in the tropical Pacific. Coral Sr/Ca records with sub-seasonal resolution provide SST proxies that complement and extend limited instrumental records. We present a new partially replicated Sr/Ca-SST record from two Galápagos corals (Isla Wolf, at 1°24'N, 91°48'W), that spans 1937-2010. The record shows high SST variance in the region, which increases nearly twofold after the late 1970s. Similarly, there is little trend in the mean until 1976, after which SSTs warm during all seasons. Both the increase in variance and the trend are strongest during the warm season, leading to progressively more anomalous conditions during El Niño events. To investigate recent changes in the eastern equatorial Pacific since the 1976/1977 climate transition, we compare the Galápagos record to a published coral Sr/Ca-SST record from Clipperton Atoll (10°18'N, 109°13'W, spanning 1874-1993; Wu et al., 2014, Palaeogeogr. Palaeoclimatol. Palaeoecol.). As in the Galápagos, Clipperton corals show increasing SSTs in all seasons after 1976. The trend at Clipperton is greater than in the Galápagos, though the variance is smaller and does not change significantly throughout the record. Finally, the north-south temperature gradient between Clipperton and Galápagos has increased slightly over the interval in which the two records overlap (1937-1993). Gridded instrumental SST data generally agree with the coral Sr/Ca-SST results, though the gridded data suggest lower variance at both sites. In sum, we show that an increase in the mean and variance of SSTs in the eastern equatorial Pacific is associated with an enhanced meridional SST gradient over the twentieth century, and especially since 1976. These results contrast with recent suggestions that a weakened meridional SST gradient in the equatorial Pacific may be leading to stronger El Niño events. Our results support the

  10. Biography of a technology: North America's power grid through the twentieth century

    NASA Astrophysics Data System (ADS)

    Cohn, Julie A.

    North Americans are among the world's most intense consumers of electricity. The vast majority in the United States and Canada access power from a network of transmission lines that stretch from the East Coast to the West Coast and from Canada to the Mexican Baja. This network, known as the largest interconnected machine in the world, evolved during the first two thirds of the twentieth century. With the very first link-ups occurring at the end of the 1890s, a wide variety of public and private utilities extended power lines to reach markets, access and manage energy resources, balance loads, realize economies of scale, provide backup power, and achieve economic stability. In 1967, utility managers and the Bureau of Reclamation connected the expansive eastern and western power pools to create the North American grid. Unlike other power grids around the world, built by single, centrally controlled entities, this large technological system emerged as the result of multiple decisions across eighty-five years of development, and negotiations for control at the economic, political, and technological levels. This dissertation describes the process of building the North American grid and the paradoxes the resulting system represents. While the grid functions as a single machine moving electricity across the continent, it is owned by many independent entities. Smooth operations suggest that the grid is a unified system; however, it operates under shared management and divided authority. In addition, although a single power network seems the logical outcome of electrification, in fact it was assembled through aggregation, not planning. Interconnections intentionally increase the robustness of individual sub-networks, yet the system itself is fragile, as demonstrated by major cascading power outages. Finally, the transmission network facilitates increased use of energy resources and consumption of power, but at certain points in the past, it also served as a technology of

    We present a review of the biological systematic research in Latin America during the twentieth century, applying a bibliometric analysis to the information contained in international databases with the largest number of biological records: Biosis (since 1969), CAB (since 1910) and Science Citation Index (since 1900), to recognize certain patterns and trends regarding the document production. We obtained 19079 documents and 1387 journals for Biosis, 14326 and 2537 for CAB, 3257 and 1636 for SCI. Of the documents, 54.6% related to new species, 15.3% dealt with morphology, 14.9% keys, 12.5% descriptions, 10.6% cases of synonymies, 6% new genera, 4.9% new geographical records, 23.6% geographical distribution, 4.2% redescriptions, and 3.6% with new nomenclatural combinations. The regions mentioned were South America with 11.9%, Central America with 4% and America (all) with 2.56%. Nineteen Latin American countries appear, whereas outside this region we found the United States of America with 12.6% of representation and Canada with 3%. Animals (65.6%) were the most studied taxa, which was 1.7 times higher than what was published for plants (37%), 11 times higher than fungi (6%) and nearly 30 times higher than microorganisms (2.3%). Out of the 155 journals that produced 66% of the papers, 76.5% were better represented in Biosis, 21.4% in CAB and 2% in SCI. Twenty-nine journals published 33% of the articles, the maximum number of records obtained was 69% for Biosis, CAB 24% and 6.9% for SCI, three (10.3%) are in biology, 11 (37.9%) in botany, 13 (44.8%) zoology, and two (6.9%) paleontology; eight of these journals (27.5%) were published in Latin America and twenty were indexed in the Science Citation Index. In the last two years more journals of the region that publish on taxonomy have been indexed, but their impact factor is still low. However, the impact factor of a number of Latin American journals that published biodiversity increased with time. Countries that are

    Research on the forcing of drought and pluvial events over North America is dominated by general circulation model experiments that often have operational limitations (e.g., computational expense, ability to simulate relevant processes, etc). We use a statistically based modeling approach to investigate sea surface temperature (SST) forcing of the twentieth century pluvial (1905-1917) and drought (1932-1939, 1948-1957, 1998-2002) events. A principal component (PC) analysis of Palmer Drought Severity Index (PDSI) from the North American Drought Atlas separates the drought variability into five leading modes accounting for 62% of the underlying variance. Over the full period spanning these events (1900-2005), the first three PCs significantly correlate with SSTs in the equatorial Pacific (PC 1), North Pacific (PC 2), and North Atlantic (PC 3), with spatial patterns (as defined by the empirical orthogonal functions) consistent with our understanding of North American drought responses to SST forcing. We use a large ensemble statistical modeling approach to determine how successfully we can reproduce these drought/pluvial events using these three modes of variability. Using Pacific forcing only (PCs 1-2), we are able to reproduce the 1948-1957 drought and 1905-1917 pluvial above a 95% random noise threshold in over 90% of the ensemble members; the addition of Atlantic forcing (PCs 1-2-3) provides only marginal improvement. For the 1998-2002 drought, Pacific forcing reproduces the drought above noise in over 65% of the ensemble members, with the addition of Atlantic forcing increasing the number passing to over 80%. The severity of the drought, however, is underestimated in the ensemble median, suggesting this drought intensity can only be achieved through internal variability or other processes. Pacific only forcing does a poor job of reproducing the 1932-1939 drought pattern in the ensemble median, and less than one third of ensemble members exceed the noise threshold

    2011-01-01

    This article explores the status, apparatus and character of forensic pathology in the inter-war period, with a special emphasis on the ‘people’s pathologist’, Bernard Spilsbury. The broad expert and public profile of forensic pathology, of which Spilsbury was the most prominent contemporary representative, will be outlined and discussed. In so doing, close attention will be paid to the courtroom strategies by which he and other experts translated their isolated post-mortem encounters with the dead body into effective testimony. Pathologists built a high-profile practice that transfixed the popular, legal and scientific imagination, and this article also explores, through the celebrated 1925 murder trial of Norman Thorne, how Spilsbury’s courtroom performance focused critical attention on the practices of pathology itself, which threatened to destabilise the status of forensic pathology. In particular, the Thorne case raised questions about the interrelation between bruising and putrefaction as sources of interpretative anxiety. Here, the question of practice is vital, especially in understanding how Spilsbury’s findings clashed with those of rival pathologists whose autopsies centred on a corpse that had undergone further putrefactive changes and that had thereby mutated as an evidentiary object. Examining how pathologists dealt with interpretative problems raised by the instability of their core investigative object enables an analysis of the ways in which pathological investigation of homicide was inflected with a series of conceptual, professional and cultural difficulties stemming in significant ways from the materiality of the corpse itself. This article presents early findings of a larger study of twentieth-century English homicide investigation which focuses on the interaction between two dominant forensic regimes: the first, outlined in part here, is a body-centred forensics, associated with the lone, ‘celebrity’ pathologist, his scalpel and

    2009-01-01

    This paper examines the International Congress of Zoology held in Washington D.C. in 1963 as a portrait of American zoologists' search for effective and rewarding relationships with both each other and the public. Organizers of the congress envisioned the congress as a last ditch effort to unify the disparate subdisciplines of zoology, overcome the barriers of specialization, and ward off the heady claims of more reductionist biologists. The problems zoologists faced as they worked to fulfill these ambitious goals illuminate some of the challenges faced by members of the naturalist tradition as they worked to establish disciplinary unity while seeking public support in the competitive world of twentieth century science.

    Using mid-twentieth-century American psychology as my focus, I explore how scientific psychology was constructed as a distinctly masculine enterprise and was navigated by those who did not conform easily to this masculine ideal. I show how women emerged as problems for science through the vigorous gatekeeping activities and personal and professional writings of disciplinary figurehead Edwin G. Boring. I trace Boring's intellectual and professional socialization into masculine science and his efforts to understand women's apparent lack of scientific eminence, efforts that were clearly undergirded by preexisting and widely shared assumptions about men's and women's capacities and preferences.

    This article investigates the numbers of 'other women' and their children up until the 1960s in Britain. It analyses 'irregular and illicit unions' in the records of the National Council for the Unmarried Mother and her Child (now One Parent Families/Gingerbread), and explores evidence on these unions in the debates over the passage of the Divorce Acts of 1923 and 1937 as well as the Legitimacy Acts of 1926 and 1959. It suggests that the prevalence of illicit unions throughout the twentieth century and before allows us to question contemporary concerns about our supposed 'divorcing society' and the decline of family life in modern Britain.

  20. The Strategic Petroleum Reserve: United States energy security, oil politics, and petroleum reserves policies in the twentieth century

    NASA Astrophysics Data System (ADS)

    Beaubouef, Bruce Andre

    The history of U.S. petroleum reserves policies in the twentieth century, including the Strategic Petroleum Reserve (SPR) program, provides a case study of the economic and political aspects of national security, and shows the ways in which the American political economy influences national security. One key problem plagued federal petroleum reserve programs and proposals throughout the twentieth century. In a political economy which traditionally placed strong emphasis upon the sanctity of private property and free markets, could the government develop an emergency petroleum reserve policy despite opposition from the private sector? Previous literature on the SPR and oil-stockpiling programs has largely disregarded the historical perspective, focusing instead upon econometric models, suggesting future oil-stockpiling policy options. This study will also make conclusions about the future of governmental oil-stockpiling policies, particularly with regard to the SPR program, but it will do so informed by a systematic history of the emergency petroleum reserve impulse in the twentieth century. Through a study of the emergency petroleum reserve impulse, one can see how the American political economy of oil and energy changed over the twentieth century. As petroleum became crucial to the military and then economic security of the United States, the federal government sought to develop emergency petroleum reserves first for the military, then for the civilian economy. But while the American petroleum industry could deliver the energy "goods" to American energy consumers at a reasonable price, the companies reigned supreme in the political equation. While that was true, federal petroleum reserve programs and proposals conflicted with and were overwhelmed by the historic American tradition of individual economic and private property rights. The depletion of American petroleum reserves changed that political equation, and the ensuing energy crises of the 1970s not only
