We carry out climate simulations for 1880-2003 with GISS modelE driven by ten measured or estimated climate forcing. An ensemble of climate model runs is carried out for each forcing acting individually and for all forcing mechanisms acting together. We compare side-by-side simulated climate change for each forcing, all forcing, observations, unforced variability among model ensemble members, and, if available, observed variability. Discrepancies between observations and simulations with all forcing are due to model deficiencies, inaccurate or incomplete forcing, and imperfect observations. Although there are notable discrepancies between model and observations, the fidelity is sufficient to encourage use of the model for simulations of future climate change. By using a fixed well-documented model and accurately defining the 1880-2003 forcing, we aim to provide a benchmark against which the effect of improvements in the model, climate forcing, and observations can be tested. Principal model deficiencies include unrealistic weak tropical El Nino-like variability and a poor distribution of sea ice, with too much sea ice in the Northern Hemisphere and too little in the Southern Hemisphere. Greatest uncertainties in the forcing are the temporal and spatial variations of anthropogenic aerosols and their indirect effects on clouds. (authors)

Full Text Available Background: The United States Medical Licensing Examination (USMLE is increasing clinical content on the Step 1 exam; thus, inclusion of clinical applications within the basic science curriculum is crucial. Including simulation activities during basic science years bridges the knowledge gap between basic science content and clinical application. Purpose: To evaluate the effects of a one-off, 1-hour cardiovascular simulation intervention on a summative assessment after adjusting for relevant demographic and academic predictors. Methods: This study was a non-randomized study using historical controls to evaluate curricular change. The control group received lecture (n l=515 and the intervention group received lecture plus a simulation exercise (nl+s=1,066. Assessment included summative exam questions (n=4 that were scored as pass/fail (≥75%. USMLE-style assessment questions were identical for both cohorts. Descriptive statistics for variables are presented and odds of passage calculated using logistic regression. Results: Undergraduate grade point ratio, MCAT-BS, MCAT-PS, age, attendance at an academic review program, and gender were significant predictors of summative exam passage. Students receiving the intervention were significantly more likely to pass the summative exam than students receiving lecture only (P=0.0003. Discussion: Simulation plus lecture increases short-term understanding as tested by a written exam. A longitudinal study is needed to assess the effect of a brief simulation intervention on long-term retention of clinical concepts in a basic science curriculum.

The distribution of snow black carbon observed in the Arctic and compared to the GISS-PUCCINI model

Directory of Open Access Journals (Sweden)

2012-09-01

Full Text Available In this study, we evaluate the ability of the latest NASA GISS composition-climate model, GISS-E2-PUCCINI, to simulate the spatial distribution of snow BC (sBC in the Arctic relative to present-day observations. Radiative forcing due to BC deposition onto Arctic snow and sea ice is also estimated. Two sets of model simulations are analyzed, where meteorology is linearly relaxed towards National Centers for Environmental Prediction (NCEP and towards NASA Modern Era Reanalysis for Research and Applications (MERRA reanalyses. Results indicate that the modeled concentrations of sBC are comparable with present-day observations in and around the Arctic Ocean, except for apparent underestimation at a few sites in the Russian Arctic. That said, the model has some biases in its simulated spatial distribution of BC deposition to the Arctic. The simulations from the two model runs are roughly equal, indicating that discrepancies between model and observations come from other sources. Underestimation of biomass burning emissions in Northern Eurasia may be the main cause of the low biases in the Russian Arctic. Comparisons of modeled aerosol BC (aBC with long-term surface observations at Barrow, Alert, Zeppelin and Nord stations show significant underestimation in winter and spring concentrations in the Arctic (most significant in Alaska, although the simulated seasonality of aBC has been greatly improved relative to earlier model versions. This is consistent with simulated biases in vertical profiles of aBC, with underestimation in the lower and middle troposphere but overestimation in the upper troposphere and lower stratosphere, suggesting that the wet removal processes in the current model may be too weak or that vertical transport is too rapid, although the simulated BC lifetime seems reasonable. The combination of observations and modeling provides a comprehensive distribution of sBC over the Arctic. On the basis of this distribution, we estimate the

SSNTD applications in science and technology - A brief review

International Nuclear Information System (INIS)

Khan, H.A.; Qureshi, I.E.

1999-01-01

The technique of Solid State Nuclear Track Detection (SSNTD) has matured since long as a viable method of charged particle detection. The usage of this method has been successfully extended to neutron detection and gamma dose measurements as well. The etch-track mechanism has been further exploited to generate a major application area of nuclear track filters. In spite of the remarkable diversity of SSNTD applications that have emerged over the years in different fields, its potential is by no means saturated. In this article, a brief review of SSNTD applications is presented with reference to contemporary interests in science and technology. For convenience, the coverage of topics is organized under broad categories of Nuclear Physics, Materials Research, Geology, Environmental Science and allied technologies. While identifying high interest areas, those with limited but innovative applications are also mentioned. In some cases, the important results are quoted for the purpose of illustrating the strength of track detection method. In general, the presentation is aimed at providing a broad perspective of current SSNTD uses instead of detailed description of individual applications. The coverage is selective rather than exhaustive and portrays authors' preferences. Some comments related to the adoption of this technique as a mainstream method of detection are also given

The MJO Transition from Shallow to Deep Convection in CloudSat/CALIPSO Data and GISS GCM Simulations

Science.gov (United States)

DelGenio, Anthony G.; Chen, Yonghua; Kim, Daehyun; Yao, Mao-Sung

2013-01-01

The relationship between convective penetration depth and tropospheric humidity is central to recent theories of the Madden-Julian oscillation (MJO). It has been suggested that general circulation models (GCMs) poorly simulate the MJO because they fail to gradually moisten the troposphere by shallow convection and simulate a slow transition to deep convection. CloudSat and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) data are analyzed to document the variability of convection depth and its relation to water vapor during the MJO transition from shallow to deep convection and to constrain GCM cumulus parameterizations. Composites of cloud occurrence for 10MJO events show the following anticipatedMJO cloud structure: shallow and congestus clouds in advance of the peak, deep clouds near the peak, and upper-level anvils after the peak. Cirrus clouds are also frequent in advance of the peak. The Advanced Microwave Scanning Radiometer for EarthObserving System (EOS) (AMSR-E) columnwater vapor (CWV) increases by;5 mmduring the shallow- deep transition phase, consistent with the idea of moisture preconditioning. Echo-top height of clouds rooted in the boundary layer increases sharply with CWV, with large variability in depth when CWV is between;46 and 68 mm. International Satellite Cloud Climatology Project cloud classifications reproduce these climatological relationships but correctly identify congestus-dominated scenes only about half the time. A version of the Goddard Institute for Space Studies Model E2 (GISS-E2) GCM with strengthened entrainment and rain evaporation that produces MJO-like variability also reproduces the shallow-deep convection transition, including the large variability of cloud-top height at intermediate CWV values. The variability is due to small grid-scale relative humidity and lapse rate anomalies for similar values of CWV. 1.

Tropical cyclones in the GISS ModelE2

Directory of Open Access Journals (Sweden)

Suzana J. Camargo

2016-07-01

Full Text Available The authors describe the characteristics of tropical cyclone (TC activity in the GISS general circulation ModelE2 with a horizontal resolution 1°×1°. Four model simulations are analysed. In the first, the model is forced with sea surface temperature (SST from the recent historical climatology. The other three have different idealised climate change simulations, namely (1 a uniform increase of SST by 2 degrees, (2 doubling of the CO2 concentration and (3 a combination of the two. These simulations were performed as part of the US Climate Variability and Predictability Program Hurricane Working Group. Diagnostics of standard measures of TC activity are computed from the recent historical climatological SST simulation and compared with the same measures computed from observations. The changes in TC activity in the three idealised climate change simulations, by comparison with that in the historical climatological SST simulation, are also described. Similar to previous results in the literature, the changes in TC frequency in the simulation with a doubling CO2 and an increase in SST are approximately the linear sum of the TC frequency in the other two simulations. However, in contrast with previous results, in these simulations the effects of CO2 and SST on TC frequency oppose each other. Large-scale environmental variables associated with TC activity are then analysed for the present and future simulations. Model biases in the large-scale fields are identified through a comparison with ERA-Interim reanalysis. Changes in the environmental fields in the future climate simulations are shown and their association with changes in TC activity discussed.

Exploring diurnal and seasonal characteristics of global carbon cycle with GISS Model E2 GCM

Science.gov (United States)

Aleinov, I. D.; Kiang, N. Y.; Romanou, A.

2017-12-01

The ability to properly model surface carbon fluxes on the diurnal and seasonal time scale is a necessary requirement for understanding of the global carbon cycle. It is also one of the most challenging tasks faced by modern General Circulation Models (GCMs) due to complexity of the algorithms and variety of relevant spatial and temporal scales. The observational data, though abundant, is difficult to interpret at the global scale, because flux tower observations are very sparse for large impact areas (such as Amazon and African rainforest and most of Siberia) and satellite missions often struggle to produce sufficiently high confidence data over the land and may be missing CO2 amounts near the surface due to the nature of the method. In this work we use the GISS Model E2 GCM to perform a subset of experiments proposed by the Coupled Climate-Carbon Cycle Model Intercomparison Project (C4MIP) and relate the results to available observations.The GISS Model E2 GCM is currently equipped with a complete global carbon cycle algorithm. Its surface carbon fluxes are computed by the Ent Terrestrial Biosphere Model (Ent TBM) over the land with observed leaf area index of the Moderate Resolution Imaging Spectrometer (MODIS) and by the NASA Ocean Biogeochemistry Model (NOBM) over the ocean. The propagation of atmospheric CO2 is performed by a generic Model E2 tracer algorithm, which is based on a quadratic upstream method (Prather 1986). We perform a series spin-up experiments for preindustrial climate conditions and fixed preindustrial atmospheric CO2 concentration. First, we perform separate spin-up simulations each for terrestrial and ocean carbon. We then combine the spun-up states and perform a coupled spin-up simulation until the model reaches a sufficient equilibrium. We then release restrictions on CO2 concentration and allow it evolve freely, driven only by simulated surface fluxes. We then study the results of the unforced run, comparing the amplitude and the phase

Cortés, Manuel E; Del Río, Juan Pablo; Vigil, Pilar

2015-02-01

The objective of this editorial is to show that a harmonious relationship between science and faith is possible, as exemplified by great saints of the Catholic Church. It begins with the definitions of science and faith, followed by an explanation of the apparent conflict between them. A few saints that constitute an example that a fruitful relationship between these two seemingly opposed realities has been possible are Saint Albert the Great, Saint John of the Cross, Saint Giuseppe Moscati, and Saint Edith Stein, among others, and this editorial highlights their deep contributions to the dialogue between faith and reason. This editorial ends with a brief discussion on whether it is possible to be both a scientist and a man of faith.

Incorporating GISs (geographic information systems) into decision support systems: Where have we come from and where do we need to go

1990-01-01

This paper reviews some of the pitfalls in the design and use of GISs that were encountered with both large and small projects for a variety of sponsors. The stand-alone, self-sufficient GIS world prevalent today does not adequately meet the needs of decision support systems. Developers of these systems are left with the difficult task of software system integration which generally produces less than adequate results. Modularization of GIS concepts is critical to the solution which involves the establishment of a GIS toolkit. More functionality and flexibility are introduced through this approach so that GIS may be truly applied'' in system development projects.

Otte, T.; Bowden, J. H.; Nolte, C. G.; Otte, M. J.; Herwehe, J. A.; Faluvegi, G.; Shindell, D. T.

2010-12-01

The WRF Model is being used at the U.S. EPA for dynamical downscaling of the NASA/GISS ModelE fields to assess regional impacts of climate change in the United States. The WRF model has been successfully linked to the ModelE fields in their raw hybrid vertical coordinate, and continuous, multi-year WRF downscaling simulations have been performed. WRF will be used to downscale decadal time slices of ModelE for recent past, current, and future climate as the simulations being conducted for the IPCC Fifth Assessment Report become available. This presentation will focus on the sensitivity to interior nudging within the RCM. The use of interior nudging for downscaled regional climate simulations has been somewhat controversial over the past several years but has been recently attracting attention. Several recent studies that have used reanalysis (i.e., verifiable) fields as a proxy for GCM input have shown that interior nudging can be beneficial toward achieving the desired downscaled fields. In this study, the value of nudging will be shown using fields from ModelE that are downscaled using WRF. Several different methods of nudging are explored, and it will be shown that the method of nudging and the choices made with respect to how nudging is used in WRF are critical to balance the constraint of ModelE against the freedom of WRF to develop its own fields.

Direct stratospheric injection of biomass burning emissions: a case study of the 2009 Australian bushfires using the NASA GISS ModelE2 composition-climate model

Science.gov (United States)

Field, Robert; From, Mike; Voulgarakis, Apostolos; Shindell, Drew; Flannigan, Mike; Bernath, Peter

2014-05-01

Direct stratospheric injection (DSI) of forest fire smoke represents a direct biogeochemical link between the land surface and stratosphere. DSI events occur regularly in the northern and southern extratropics, and have been observed across a wide range of measurements, but their fate and effects are not well understood. DSIs result from explosive, short-lived fires, and their plumes stand out from background concentrations immediately. This makes it easier to associate detected DSIs to individual fires and their estimated emissions. Because the emissions pulses are brief, chemical decay can be more clearly assessed, and because the emissions pulses are so large, a wide range of rare chemical species can be detected. Observational evidence suggests that they can persist in the stratosphere for several months, enhance ozone production, and be self-lofted to the middle stratosphere through shortwave absorption and diabatic heating. None of these phenomena have been evaluated, however, with a physical model. To that end, we are simulating the smoke plumes from the February 2009 Australia 'Black Saturday' bushfires using the NASA GISS ModelE2 composition-climate model, nudged toward horizontal winds from reanalysis. To-date, this is the best-observed DSI in the southern hemisphere. Chemical and aerosol signatures of the plume were observed in a wide array of limb and nadir satellite retrievals. Detailed estimates of fuel consumption and injection height have been made because of the severity of the fires. Uncommon among DSIs events was a large segment of the plume that entrained into the upper equatorial easterlies. Preliminary modeling results show that the relative strengths of the equatorial and extratropical plume segments are sensitive to the plume's initial injection height. This highlights the difficulty in reconciling uncertainty in the reanalysis over the Southern Hemisphere with fairly-well constrained estimates of fire location and injection height at the

Improved Upper Ocean/Sea Ice Modeling in the GISS GCM for Investigating Climate Change

Science.gov (United States)

1998-01-01

This project built on our previous results in which we highlighted the importance of sea ice in overall climate sensitivity by determining that for both warming and cooling climates, when sea ice was not allowed to change, climate sensitivity was reduced by 35-40%. We also modified the GISS 8 deg x lO deg atmospheric GCM to include an upper-ocean/sea-ice model involving the Semtner three-layer ice/snow thermodynamic model, the Price et al. (1986) ocean mixed layer model and a general upper ocean vertical advection/diffusion scheme for maintaining and fluxing properties across the pycnocline. This effort, in addition to improving the sea ice representation in the AGCM, revealed a number of sensitive components of the sea ice/ocean system. For example, the ability to flux heat through the ice/snow properly is critical in order to resolve the surface temperature properly, since small errors in this lead to unrestrained climate drift. The present project, summarized in this report, had as its objectives: (1) introducing a series of sea ice and ocean improvements aimed at overcoming remaining weaknesses in the GCM sea ice/ocean representation, and (2) performing a series of sensitivity experiments designed to evaluate the climate sensitivity of the revised model to both Antarctic and Arctic sea ice, determine the sensitivity of the climate response to initial ice distribution, and investigate the transient response to doubling CO2.

Evaluation of aerosol distributions in the GISS-TOMAS global aerosol microphysics model with remote sensing observations

Directory of Open Access Journals (Sweden)

Y. H. Lee

2010-03-01

Full Text Available The Aerosol Optical Depth (AOD and Angstrom Coefficient (AC predictions in the GISS-TOMAS model of global aerosol microphysics are evaluated against remote sensing data from MODIS, MISR, and AERONET. The model AOD agrees well (within a factor of two over polluted continental (or high sulfate, dusty, and moderate sea-salt regions but less well over the equatorial, high sea-salt, and biomass burning regions. Underprediction of sea-salt in the equatorial region is likely due to GCM meteorology (low wind speeds and high precipitation. For the Southern Ocean, overprediction of AOD is very likely due to high sea-salt emissions and perhaps aerosol water uptake in the model. However, uncertainties in cloud screening at high latitudes make it difficult to evaluate the model AOD there with the satellite-based AOD. AOD in biomass burning regions is underpredicted, a tendency found in other global models but more severely here. Using measurements from the LBA-SMOCC 2002 campaign, the surface-level OC concentration in the model are found to be underpredicted severely during the dry season while much less severely for EC concentration, suggesting the low AOD in the model is due to underpredictions in OM mass. The potential for errors in emissions and wet deposition to contribute to this bias is discussed.

We show a lot of respect for science today. To back up our claims, we tend to appeal to scientific methods. It seems that we all agree that these methods are effective for gaining the truth. We can ask why science has its special status as a supplier of knowledge about our external world and our bodies. Of course, one should not always trust what scientists say. Nonetheless, epistemological justification of scientific claims is really a big project for philosophers of science. Philosophers of science are interested in knowing how science proves what it does claim and why it gives us good reasons to take these claims seriously. These questions are epistemological questions. Epistemology is a branch of philosophy which deals with knowledge claims and justification. Besides epistemological questions, metaphysical and ethical issues in science are worthy of philosophical scrutiny. This paper gives a short survey of these intellectually demanding issues.

Multiple GISS AGCM Hindcasts and MSU Versions of 1979-1998

Science.gov (United States)

Shah, Kathryn Pierce; Rind, David; Druyan, Leonard; Lonergan, Patrick; Chandler, Mark

1998-01-01

Multiple realizations of the 1979-1998 time period have been simulated by the Goddard Institute for Space Studies Atmospheric General Circulation Model (GISS AGCM) to explore its responsiveness to accumulated forcings, particularly over sensitive agricultural regions. A microwave radiative transfer postprocessor has produced the AGCM's lower tropospheric, tropospheric and lower stratospheric brightness temperature (Tb) time series for correlations with the various Microwave Sounding Unit (MSU) time series available. MSU maps of monthly means and anomalies were also used to assess the AGCM's mean annual cycle and regional variability. Seven realizations by the AGCM were forced by observed sea surface temperatures (sst) through 1992 to gather rough standard deviations associated with internal model variability. Subsequent runs hindcast January 1979 through April 1998 with an accumulation of forcings: observed ssts, greenhouse gases, stratospheric volcanic aerosols. stratospheric and tropospheric ozone and tropospheric sulfate and black carbon aerosols. The goal of narrowing gaps between AGCM and MSU time series was complicated by MSU time series, by Tb simulation concerns and by unforced climatic variability in the AGCM and in the real world. Lower stratospheric Tb correlations between the AGCM and MSU for 1979-1998 reached as high as 0.91 +/-0.16 globally with sst, greenhouse gases, volcanic aerosol, stratospheric ozone forcings and tropospheric aerosols. Mid-tropospheric Tb correlations reached as high as 0.66 +/-.04 globally and 0.84 +/-.02 in the tropics. Oceanic lower tropospheric Tb correlations similarly reached 0.61 +/-.06 globally and 0.79 +/-.02 in the tropics. Of the sensitive agricultural areas considered, Nordeste in northeastern Brazil was simulated best with mid-tropospheric Tb correlations up to 0.75 +/- .03. The two other agricultural regions, in Africa and in the northern mid-latitudes, suffered from higher levels of non-sst variability. Zimbabwe

Full Text Available Comics are a popular art form especially among children and as such provide a potential medium for science education and communication. In an attempt to present science comics in a museum exhibit I found many science themed comics and graphic books. Here I attempt to provide an overview of already available comics that communicate science, the genre of ‘science comics’. I also provide a quick literature review for evidence that comics can indeed be efficiently used for promoting scientific literacy via education and communication. I address the issue of lack of studies about science comics and their readers and suggest some possible reasons for this as well as some questions that could be addressed in future studies on the effect these comics may have on science communication.

New approach to technology advocated at House briefing

Science.gov (United States)

White, Catherine

At a House Committee on Science, Space and Technology briefing on July 26, witnesses from the Institute for Policy Studies testified in support of a new approach to technology emphasizing science and technology for the public good and focusing on small, widely distributed projects.The testimony was based on the institute's recently published book, Technology for the Common Good, which concludes that in the wake of the Cold War era, technology policy should advance the broad public good over the narrow interests of a few businesses and budget-hungry agencies. The book echoes a report released by the Carnegie Commission on Science, Technology, and Government several weeks ago.

The sample included 128 prostate cancer patients recruited from urology and general oncology clinics at two Chicago-area hospitals. The main outcome measures were: A 36-item PF item bank that included a 5-item short form (BriefPF and the 10-item PF subscale (PF-10 from the Medical Outcomes Study SF-36. Validity, information function, and relative precision (calculated using Rasch analysis and raw scores of the BriefPF were compared to the PF-10 and the full PF item bank. We found that the BriefPF and PF-10 were strongly correlated (r = 0.85 with the PF bank, and all three scales differentiated patients according to performance status (FPF bank(2,124 = 32.51 P < 0.001, FPF-10(2,121 = 27.35 P < 0.001, FBriefPF (2,123 = 38.40 P < 0.001. BriefPF has excellent precision relative to the PF-10 in measuring patients with different performance status levels. The Rasch-based information function indicated that the BriefPF was more informative than PF-10 in measuring moderate to higher functioning patients. Hence, the BriefPF offers a parsimonious and precise measure of PF for use among men with prostate cancer, and may aid in the timely inclusion of patient-reported outcomes in treatment decision-making.Keywords: quality-of-life, item bank, short-form, Medical Outcomes Study

Dangerous human-made interference with climate: a GISS modelE study

Directory of Open Access Journals (Sweden)

J. Hansen

2007-01-01

Full Text Available We investigate the issue of "dangerous human-made interference with climate" using simulations with GISS modelE driven by measured or estimated forcings for 1880–2003 and extended to 2100 for IPCC greenhouse gas scenarios as well as the "alternative" scenario of Hansen and Sato (2004. Identification of "dangerous" effects is partly subjective, but we find evidence that added global warming of more than 1°C above the level in 2000 has effects that may be highly disruptive. The alternative scenario, with peak added forcing ~1.5 W/m2 in 2100, keeps further global warming under 1°C if climate sensitivity is ~3°C or less for doubled CO2. The alternative scenario keeps mean regional seasonal warming within 2σ (standard deviations of 20th century variability, but other scenarios yield regional changes of 5–10σ, i.e. mean conditions outside the range of local experience. We conclude that a CO2 level exceeding about 450 ppm is "dangerous", but reduction of non-CO2 forcings can provide modest relief on the CO2 constraint. We discuss three specific sub-global topics: Arctic climate change, tropical storm intensification, and ice sheet stability. We suggest that Arctic climate change has been driven as much by pollutants (O3, its precursor CH4, and soot as by CO2, offering hope that dual efforts to reduce pollutants and slow CO2 growth could minimize Arctic change. Simulated recent ocean warming in the region of Atlantic hurricane formation is comparable to observations, suggesting that greenhouse gases (GHGs may have contributed to a trend toward greater hurricane intensities. Increasing GHGs cause significant warming in our model in submarine regions of ice shelves and shallow methane hydrates, raising concern about the potential for accelerating sea level rise and future positive feedback from methane release. Growth of non-CO2 forcings has slowed in recent years, but CO2 emissions are now surging well above the alternative scenario. Prompt

International Nuclear Information System (INIS)

1992-01-01

The Plasma Science Committee (PLSC) of the National Research Council (NRC) is charged with monitoring the health of the field of plasma science in the United States. Accordingly, the Committee identifies and examines both broad and specific issues affecting the field. Regular meetings, teleconferences, briefings from agencies and the scientific community, the formation of study panels to prepare reports, and special symposia are among the mechanisms used by the PLSC to meet its charge. This progress report presents a review of PLSC activities from July 15, 1991 to May 31, 1992. The details of prior activities are discussed in earlier reports. This report also includes the status of activities associated with the PLSC study on opportunities in plasma science and technology. During the above period, the PLSC has continued to track and participate in, when requested, discussions on the health of the field. Much of the perspective of the PLSC has been presented in the recently-published report Research Briefing on Contemporary Problems in Plasma Science. That report has served as the basis for briefings to representatives of the federal government as well as the community-at-large. In keeping with its charge to identify and highlight specific areas for scientific and technological opportunities, the PLSC completed publication of the report Plasma Processing of Materials: Scientific and Technological Opportunities and launched a study on new opportunities in plasma science and technology

This paper reviews several literatures concerning the theories and model that could be applied for science motivation for upper secondary school learners (16-17 years old) in order to make the learning experience more amazing and useful. The embedment of AR in science could bring an awe-inspiring transformation on learners' viewpoint towards the respective subject matters. Augmented Reality is able to present the real and virtual learning experience with the addition of multiple media without replacing the real environment. Due to the unique feature of AR, it attracts the mass attention of researchers to implement AR in science learning. This impressive technology offers learners with the ultimate visualization and provides an astonishing and transparent learning experience by bringing to light the unseen perspective of the learning content. This paper will attract the attention of researchers in the related field as well as academicians in the related discipline. This paper aims to propose several related theoretical guidance that could be applied in science motivation to transform the learning in an effective way.

Hormesis in Regulatory risk assessment - Science and Science Policy.

Gray, George

2011-01-01

This brief commentary will argue that whether hormesis is considered in regulatory risk assessment is a matter less of science than of science policy. I will first discuss the distinction between science and science policy and their roles in regulatory risk assessment. Then I will focus on factors that influence science policy, especially as it relates to the conduct of risk assessments to inform regulatory decisions, with a focus on the U.S. Environmental Protection Agency (EPA). The key questions will then be how does hormesis interact with current concepts of science and science policy for risk assessment? Finally, I look ahead to factors that may increase, or decrease, the likelihood of hormesis being incorporated into regulatory risk assessment.

Giving students a fair start to become productive and responsible contributors in the 21st century workforce and society depends on our ability to help them develop: (1) A global view of the world; (2) Problem-solving and/or reasoning abilities; (3) Basic scientific and technical literacy; and (4) A multi-disciplinary understanding of how humans and nature interact with the earth system. The Institute on Climate and Planets (ICP) in New York City is NASA Goddard Institute for Space Studies' (GISS) response to the national challenge to give students a fair start to become productive in America's workforce and society, GISS is part of the Earth Science Director at NASA Goddard Space Flight Center in Maryland and a component of Columbia University's Earth Institute, a university-wide initiative whose mission is to understand our planet so as to enhance its sustainability. In 1994 Jim Hansen, several of his GISS and Columbia University colleagues and Fitzgerald Bramwell, the former Director of the New York City Alliance for Minority Participation at City University of New York, launched the ICP. ICP contributes to NASA education and minority outreach goals by directly involving underrepresented college, high school and junior high school students and their educators in research. ICP takes advantage of the interest of many civil servants and Columbia University research scientists at GISS to involve students and educators on multi-level research teams working on problems at the core of NASA's Earth Science Enterprise - advancing our understanding of Earth s climate, climate variability, and climate impacts.

The Added Value to Global Model Projections of Climate Change by Dynamical Downscaling: A Case Study over the Continental U.S. using the GISS-ModelE2 and WRF Models

Science.gov (United States)

Racherla, P. N.; Shindell, D. T.; Faluvegi, G. S.

2012-01-01

Dynamical downscaling is being increasingly used for climate change studies, wherein the climates simulated by a coupled atmosphere-ocean general circulation model (AOGCM) for a historical and a future (projected) decade are used to drive a regional climate model (RCM) over a specific area. While previous studies have demonstrated that RCMs can add value to AOGCM-simulated climatologies over different world regions, it is unclear as to whether or not this translates to a better reproduction of the observed climate change therein. We address this issue over the continental U.S. using the GISS-ModelE2 and WRF models, a state-of-the-science AOGCM and RCM, respectively. As configured here, the RCM does not effect holistic improvement in the seasonally and regionally averaged surface air temperature or precipitation for the individual historical decades. Insofar as the climate change between the two decades is concerned, the RCM does improve upon the AOGCM when nudged in the domain proper, but only modestly so. Further, the analysis indicates that there is not a strong relationship between skill in capturing climatological means and skill in capturing climate change. Though additional research would be needed to demonstrate the robustness of this finding in AOGCM/RCM models generally, the evidence indicates that, for climate change studies, the most important factor is the skill of the driving global model itself, suggesting that highest priority should be given to improving the long-range climate skill of AOGCMs.

The NPOESS Preparatory Project Science Data Segment: Brief Overview

Science.gov (United States)

Schweiss, Robert J.; Ho, Evelyn; Ullman, Richard; Samadi, Shahin

2006-01-01

The NPOESS Preparatory Project (NPP) provides remotely-sensed land, ocean, atmospheric, ozone, and sounder data that will serve the meteorological and global climate change scientific communities while also providing risk reduction for the National Polar-orbiting Operational Environmental Satellite System (NPOESS), the U.S. Government s future low-Earth orbiting satellite system monitoring global weather and environmental conditions. NPOESS and NPP are a new era, not only because the sensors will provide unprecedented quality and volume of data but also because it is a joint mission of three federal agencies, NASA, NOAA, and DoD. NASA's primary science role in NPP is to independently assess the quality of the NPP science and environmental data records. Such assessment is critical for making NPOESS products the best that they can be for operational use and ultimately for climate studies. The Science Data Segment (SDS) supports science assessment by assuring the timely provision of NPP data to NASA s science teams organized by climate measurement themes. The SDS breaks down into nine major elements, an input element that receives data from the operational agencies and acts as a buffer, a calibration analysis element, five elements devoted to measurement based quality assessment, an element used to test algorithmic improvements, and an element that provides overall science direction. This paper will describe how the NPP SDS will leverage on NASA experience to provide a mission-reliable research capability for science assessment of NPP derived measurements.

Eocene climate and Arctic paleobathymetry: A tectonic sensitivity study using GISS ModelE-R

Science.gov (United States)

Roberts, C. D.; Legrande, A. N.; Tripati, A. K.

2009-12-01

The early Paleogene (65-45 million years ago, Ma) was a ‘greenhouse’ interval with global temperatures warmer than any other time in the last 65 Ma. This period was characterized by high levels of CO2, warm high-latitudes, warm surface-and-deep oceans, and an intensified hydrological cycle. Sediments from the Arctic suggest that the Eocene surface Arctic Ocean was warm, brackish, and episodically enabled the freshwater fern Azolla to bloom. The precise mechanisms responsible for the development of these conditions remain uncertain. We present equilibrium climate conditions derived from a fully-coupled, water-isotope enabled, general circulation model (GISS ModelE-R) configured for the early Eocene. We also present model-data comparison plots for key climatic variables (SST and δ18O) and analyses of the leading modes of variability in the tropical Pacific and North Atlantic regions. Our tectonic sensitivity study indicates that Northern Hemisphere climate would have been very sensitive to the degree of oceanic exchange through the seaways connecting the Arctic to the Atlantic and Tethys. By restricting these seaways, we simulate freshening of the surface Arctic Ocean to ~6 psu and warming of sea-surface temperatures by 2°C in the North Atlantic and 5-10°C in the Labrador Sea. Our results may help explain the occurrence of low-salinity tolerant taxa in the Arctic Ocean during the Eocene and provide a mechanism for enhanced warmth in the north western Atlantic. We also suggest that the formation of a volcanic land-bridge between Greenland and Europe could have caused increased ocean convection and warming of intermediate waters in the Atlantic. If true, this result is consistent with the theory that bathymetry changes may have caused thermal destabilisation of methane clathrates in the Atlantic.

Climate implications of carbonaceous aerosols: An aerosol microphysical study using the GISS/MATRIX climate model

International Nuclear Information System (INIS)

Bauer, Susanne E.; Menon, Surabi; Koch, Dorothy; Bond, Tami; Tsigaridis, Kostas

2010-01-01

Recently, attention has been drawn towards black carbon aerosols as a likely short-term climate warming mitigation candidate. However the global and regional impacts of the direct, cloud-indirect and semi-direct forcing effects are highly uncertain, due to the complex nature of aerosol evolution and its climate interactions. Black carbon is directly released as particle into the atmosphere, but then interacts with other gases and particles through condensation and coagulation processes leading to further aerosol growth, aging and internal mixing. A detailed aerosol microphysical scheme, MATRIX, embedded within the global GISS modelE includes the above processes that determine the lifecycle and climate impact of aerosols. This study presents a quantitative assessment of the impact of microphysical processes involving black carbon, such as emission size distributions and optical properties on aerosol cloud activation and radiative forcing. Our best estimate for net direct and indirect aerosol radiative forcing change is -0.56 W/m 2 between 1750 and 2000. However, the direct and indirect aerosol effects are very sensitive to the black and organic carbon size distribution and consequential mixing state. The net radiative forcing change can vary between -0.32 to -0.75 W/m 2 depending on these carbonaceous particle properties. Assuming that sulfates, nitrates and secondary organics form a coating shell around a black carbon core, rather than forming a uniformly mixed particles, changes the overall net radiative forcing from a negative to a positive number. Black carbon mitigation scenarios showed generally a benefit when mainly black carbon sources such as diesel emissions are reduced, reducing organic and black carbon sources such as bio-fuels, does not lead to reduced warming.

After its launch on 2 December 1995, SOHO travelled to take up a special orbit 1.5 million kilometres away on the sunward side of the Earth, where the Sun never sets. The full scientific programme began in April 1996. The occasion for the briefing is the celebration of that second anniversary and of the mission's extension to 2003. Organized by the European Space Agency, the briefing will be hosted by the Rutherford Appleton Laboratory, which is near Oxford. Leading scientists associated with SOHO will announce to the press some remarkable new discoveries about the Sun's interior, atmosphere and solar wind. They will also briefly review the main achievements of the past two years. The role of SOHO as the chief watchdog for storms on the Sun that may affect the Earth will be demonstrated. Europe's creation of the finest spacecraft ever built to observe the Sun will be recalled by a top engineer from ESA. A speaker from NASA will explain transatlantic contributions to SOHO, which is a project of international cooperation between ESA and NASA. ESA's director of science will also be present, to relate SOHO to ESA's general science programme. A lunch-time talk by the BNSC's director of science completes the line-up of speakers. This is also an exceptional opportunity for the press to meet and interview scientists from all over Europe and the USA, who are attending a meeting at the Rutherford Appleton Laboratory of SOHO's Science Working Team (SWT). Journalists are usually excluded from such meetings. The Rutherford Appleton Laboratory plays a prominent part in SOHO, particularly through its provision of the CDS ultraviolet spectrometer.

Skinner, Ellen; Saxton, Emily; Currie, Cailin; Shusterman, Gwen

2017-11-01

As part of long-standing efforts to promote undergraduates' success in science, researchers have investigated the instructional strategies and motivational factors that promote student learning and persistence in science coursework and majors. This study aimed to create a set of brief measures that educators and researchers can use as tools to examine the undergraduate motivational experience in science classes. To identify key motivational processes, we drew on self-determination theory (SDT), which holds that students have fundamental needs - to feel competent, related, and autonomous - that fuel their intrinsic motivation. When educational experiences meet these needs, students engage more energetically and learn more, cumulatively contributing to a positive identity as a scientist. Based on information provided by 1013 students from 8 classes in biology, chemistry, and physics, we constructed conceptually focused and psychometrically sound survey measures of three sets of motivational factors: (1) students' appraisals of their own competence, autonomy, and relatedness; (2) the quality of students' behavioural and emotional engagement in academic work; and (3) students' emerging identities as scientists, including their science identity, purpose in science, and science career plans. Using an iterative confirmatory process, we tested short item sets for unidimensionality and internal consistency, and then cross-validated them. Tests of measurement invariance showed that scales were generally comparable across disciplines. Most importantly, scales and final course grades showed correlations consistent with predictions from SDT. These measures may provide a window on the student motivational experience for educators, researchers, and interventionists who aim to improve the quality of undergraduate science teaching and learning.

Apart from the journals they produce, scientific societies play an important role in communicating scientific findings and norms to the broader society. The American Association for the Advancement of Science (AAAS) includes among its goals to promote and defend the integrity of science and its use; provide a voice for science on societal issues; promote the responsible use of science in public policy; and increase public engagement with science and technology. AAAS websites and programs, including Communicating Science (www.aaas.org/communicatingscience), Working with Congress (http://www.aaas.org/spp/cstc/wwc/book.htm) and ScienceCareers.org (http://sciencecareers.sciencemag.org), provide tools for scientists to become more directly engaged in effectively communicating their findings and involved in the policy process. Education programs work to build the next generation of scientists and a science-literate public. To bridge the current communication gap between scientists, the public and policymakers, AAAS, like other scientific societies, maintains policy and outreach programs with limited budgets and staff. AAAS works to engage policymakers and provide scientific underpinning to key issues through congressional briefings, meetings, policy briefs, and media outreach. AAAS responds to challenges to accepted scientific findings and processes through op-eds, letters to government officials, resolutions, and Board statements. Some of these initiatives occur on a local level in partnership with local civic leaders, whose endorsement makes them more powerful. On a national scale, they assure that the voice of science is included in the debate. The changing media landscape presents opportunities and challenges for future AAAS endeavors.

Constructivism in Science and Science Education: A Philosophical Critique

Science.gov (United States)

Nola, Robert

This paper argues that constructivist science education works with an unsatisfactory account of knowledge which affects both its account of the nature of science and of science education. The paper begins with a brief survey of realism and anti-realism in science and the varieties of constructivism that can be found. In the second section the important conception of knowledge and teaching that Plato develops in the Meno is contrasted with constructivism. The section ends with an account of the contribution that Vico (as understood by constructivists), Kant and Piaget have made to constructivist doctrines. Section three is devoted to a critique of the theory of knowledge and the anti-realism of von Glaserfeld. The final section considers the connection, or lack of it, between the constructivist view of science and knowledge and the teaching of science.

A Brief History of the Soil Science Society of America

Science.gov (United States)

Brevik, Eric C.

2013-04-01

The Soil Science Society of America (SSSA) was officially born on November 18, 1936 at the Mayflower Hotel in Washington, D.C. with Richard Bradfield as the first President. SSSA was created from the merger of the American Soil Survey Association and the Soils Section of American Society of Agronomy (ASA). Six sections were established: 1) physics, 2) chemistry, 3) microbiology, 4) fertility, 5) morphology, and 6) technology, and total membership was less than 200. The first issue of SSSA Journal, then called SSSA Proceedings, published 87 items totaling 526 pages. The first recorded bank balance for SSSA was at the end of the 1937-38 fiscal year, and showed the Society to be worth 1,300.03. The Soils Section of ASA became the official American section of the International Society of Soil Science in 1934, and the new SSSA inherited that distinction which it retains to this day. SSSA has grown significantly since those early days. The original six sections have grown to 11 divisions, and some of those divisions have changed their names to reflect changes occurring within soil science. For example, the original section 5, morphology, is now Division S05 - Pedology after spending many years under other names such as Division V - Soil Classification and Division S-5 - Soil Genesis, Morphology, and Classification. SSSA was incorporated in the State of Wisconsin, USA on 22 January, 1952. Several awards have been developed to recognize achievement in the field of soil science, including the SSSA Presidential Award, Don and Betty Kirkham Soil Physics Award, Emil Truog Soil Science Award, International Soil Science Award, Irrometer Professional Certification Service Award, L.R. Ahuja Ag Systems Modeling Award, Marion L. and Chrystie M. Jackson Soil Science Award, Soil Science Applied Research Award, Soil Science Distinguished Service Award, Soil Science Education Award, Soil Science Industry and Professional Leadership Award, Soil Science Research Award, and SSSA Early

Seeking missing pieces in science concept assessments: Reevaluating the Brief Electricity and Magnetism Assessment through Rasch analysis

Lin Ding

2014-02-01

Full Text Available Discipline-based science concept assessments are powerful tools to measure learners’ disciplinary core ideas. Among many such assessments, the Brief Electricity and Magnetism Assessment (BEMA has been broadly used to gauge student conceptions of key electricity and magnetism (E&M topics in college-level introductory physics courses. Differing from typical concept inventories that focus only on one topic of a subject area, BEMA covers a broad range of topics in the electromagnetism domain. In spite of this fact, prior studies exclusively used a single aggregate score to represent individual students’ overall understanding of E&M without explicating the construct of this assessment. Additionally, BEMA has been used to compare traditional physics courses with a reformed course entitled Matter and Interactions (M&I. While prior findings were in favor of M&I, no empirical evidence was sought to rule out possible differential functioning of BEMA that may have inadvertently advantaged M&I students. In this study, we used Rasch analysis to seek two missing pieces regarding the construct and differential functioning of BEMA. Results suggest that although BEMA items generally can function together to measure the same construct of application and analysis of E&M concepts, several items may need further revision. Additionally, items that demonstrate differential functioning for the two courses are detected. Issues such as item contextual features and student familiarity with question settings may underlie these findings. This study highlights often overlooked threats in science concept assessments and provides an exemplar for using evidence-based reasoning to make valid inferences and arguments.

Jonathan Marx

2004-10-01

Full Text Available Science fairs at one time started out with an interest of increasing participation in the sciences. But as time has passed, the definition of science has been narrowed to the point where any possible social science project has been eliminated in favor of the bench sciences only. Even here, natural curiosity of students has been deemphasized. It is not surprising that science majors in the USA are becoming fewer and fewer given the narrowing of the disciplines. Young people are discouraged from majoring in science by the science establishment.

von Becker, K

1979-01-01

A brief review of the development of nuclear science and technology in China is given. It is stated that the change of leadership in China has brought about a radical revision of the attitude towards the science and technology. In the plan of the development of nuclear science and technology adopted in 1973 a great emphasis is laid on investigations in the field of high energy physics. For instance, it is planned to construct, before 1983, a 30-50 GeV proton accelerator. A brief description is given of main nuclear research institutes in Phangshan, Peking and Shanghai which are shown to Western visitors. It is indicated that at these institutes there are the only two research reactors in China, a 3.5-MW LWR and 10 MW HWR, two cyclotrons and a 90-cm tokamak. These institutes also conduct investigations on solid-state physics, low-temperature physics, high-pressure physics, lasers, radiation biology, radiation chemistry, etc.

The Plasma Science Committee (PLSC) of the National Research Council (NRC) is charged with monitoring the health of the field of plasma science in the United States and identifies and examines both broad and specific issues affecting the field. Regular meetings, teleconferences, briefings from agencies and the scientific community, the formation of study panels to prepare reports, and special symposia are among the mechanisms used by the PLSC to meet its charge. During July 1992, the PLSC sponsored a workshop on nonneutral plasmas in traps. Although no written report on the workshop results, was prepared for public distribution, a summary of highlights was provided to the OPST Subpanel on Nonneutral Plasmas. The PLSC also continued its follow-up briefings and discussions on the results of the results of the report Plasma Processing of materials. Scientific and Technological Opportunities. As a result of these activities, the Committee is now working with the NRC Committee on Atomic, Molecular, and Optical Sciences (CAMOS) to organize a symposium on database needs in plasma processing of materials

Assessing ocean vertical mixing schemes for the study of climate change

Science.gov (United States)

Howard, A. M.; Lindo, F.; Fells, J.; Tulsee, V.; Cheng, Y.; Canuto, V.

2014-12-01

Climate change is a burning issue of our time. It is critical to know the consequences of choosing "business as usual" vs. mitigating our emissions for impacts e.g. ecosystem disruption, sea-level rise, floods and droughts. To make predictions we must model realistically each component of the climate system. The ocean must be modeled carefully as it plays a critical role, including transporting heat and storing heat and dissolved carbon dioxide. Modeling the ocean realistically in turn requires physically based parameterizations of key processes in it that cannot be explicitly represented in a global climate model. One such process is vertical mixing. The turbulence group at NASA-GISS has developed a comprehensive new vertical mixing scheme (GISSVM) based on turbulence theory, including surface convection and wind shear, interior waves and double-diffusion, and bottom tides. The GISSVM is tested in stand-alone ocean simulations before being used in coupled climate models. It is also being upgraded to more faithfully represent the physical processes. To help assess mixing schemes, students use data from NASA-GISS to create visualizations and calculate statistics including mean bias and rms differences and correlations of fields. These are created and programmed with MATLAB. Results with the commonly used KPP mixing scheme and the present GISSVM and candidate improved variants of GISSVM will be compared between stand-alone ocean models and coupled models and observations. This project introduces students to modeling of a complex system, an important theme in contemporary science and helps them gain a better appreciation of climate science and a new perspective on it. They also gain familiarity with MATLAB, a widely used tool, and develop skills in writing and understanding programs. Moreover they contribute to the advancement of science by providing information that will help guide the improvement of the GISSVM and hence of ocean and climate models and ultimately our

Preditive Models And Health Sciences: A Brief Analysis

Directory of Open Access Journals (Sweden)

Jair Sales Paulino, Msc

2017-07-01

Full Text Available Background: Predictive Models are an important tool in event predicting and health planning. Despite this, there are few works focusing this area. Thus, the analysis of the real benefits of these models in Health Sciences is necessary to be performed. Results: Predictive techniques largely evolved in second half of XX century. The development of AR, MA, ARMA, ARIMA and SARIMA models, through Box-Jenkins methodology, constitute a robust conjunct of mechanisms able to help in solution of epidemiological modeling problems, mainly in Health Sciences, once it allows to evaluate individual characteristics of living beings and its correlation with pathologies in the same space-time. Nevertheless, AR, MA and ARMA does not have tendency in seasonality, which weakens the analysis. Conclusions: To predict the natural history of endemic/epidemic and its health-disease processes in a determined population is a sine que non condition to its adequate management in Public Health context and in adoption of affirmative measures concerning health promotion. Thus, the predictive models, with emphasis in ARIMA, SARIMA, Artificial Neural Networks and Formalism of Copulas are alternatives that can be feasible.

Forsyth, Katherine L; Hildebrand, Emily A; Hallbeck, M Susan; Branaghan, Russell J; Blocker, Renaldo C

2018-02-24

Preoperative briefings have been proven beneficial for improving team performance in the operating room. However, there has been minimal research regarding team briefings in specific surgical domains. As part of a larger project to develop a briefing structure for gynecological surgery, the study aimed to better understand the current state of pre-operative team briefings in one department of an academic hospital. Twenty-four team briefings were observed and video recorded. Communication was analyzed and social network metrics were created based on the team member verbal interactions. Introductions occurred in only 25% of the briefings. Network analysis revealed that average team briefings exhibited a hierarchical structure of communication, with the surgeon speaking the most frequently. The average network for resident-led briefings displayed a non-hierarchical structure with all team members communicating with the resident. Briefings conducted without a standardized protocol can produce variable communication between the role leading and the team members present. Copyright © 2018 Elsevier Ltd. All rights reserved.

Contributions from Women to the Radiation Sciences: A Brief History.

Science.gov (United States)

Martinez, Nicole E

2017-04-01

Contributions from men to radiation science are well known, particularly the early contributions from such luminaries as William Roentgen, James Chadwick, Niels Bohr, Robert Oppenheimer, and the like. Although not ignored per se, beyond Marie Curie and Lise Meitner, the contributions of female nuclear scientists are not as widely recognized. This paper provides a concise historical summary of contributions to radiation science from the discovery of radiation through the current status of international leadership within the radiation protection community. Beyond lead scientists and academics, this paper also considers support personnel as well as the role women have played in the advancement of radiation epidemiology.

Dependence of stratocumulus-topped boundary-layer entrainment on cloud-water sedimentation: Impact on global aerosol indirect effect in GISS ModelE3 single column model and global simulations

Science.gov (United States)

Ackerman, A. S.; Kelley, M.; Cheng, Y.; Fridlind, A. M.; Del Genio, A. D.; Bauer, S.

2017-12-01

Reduction in cloud-water sedimentation induced by increasing droplet concentrations has been shown in large-eddy simulations (LES) and direct numerical simulation (DNS) to enhance boundary-layer entrainment, thereby reducing cloud liquid water path and offsetting the Twomey effect when the overlying air is sufficiently dry, which is typical. Among recent upgrades to ModelE3, the latest version of the NASA Goddard Institute for Space Studies (GISS) general circulation model (GCM), are a two-moment stratiform cloud microphysics treatment with prognostic precipitation and a moist turbulence scheme that includes an option in its entrainment closure of a simple parameterization for the effect of cloud-water sedimentation. Single column model (SCM) simulations are compared to LES results for a stratocumulus case study and show that invoking the sedimentation-entrainment parameterization option indeed reduces the dependence of cloud liquid water path on increasing aerosol concentrations. Impacts of variations of the SCM configuration and the sedimentation-entrainment parameterization will be explored. Its impact on global aerosol indirect forcing in the framework of idealized atmospheric GCM simulations will also be assessed.

Terzioglu, Fatma; Kuchment, Peter; Kunyansky, Leonid

2018-05-01

While most of Radon transform applications to imaging involve integrations over smooth sub-manifolds of the ambient space, lately important situations have appeared where the integration surfaces are conical. Three of such applications are single scatter optical tomography, Compton camera medical imaging, and homeland security. In spite of the similar surfaces of integration, the data and the inverse problems associated with these modalities differ significantly. In this article, we present a brief overview of the mathematics arising in Compton camera imaging. In particular, the emphasis is made on the overdetermined data and flexible geometry of the detectors. For the detailed results, as well as other approaches (e.g. smaller-dimensional data or restricted geometry of detectors) the reader is directed to the relevant publications. Only a brief description and some references are provided for the single scatter optical tomography. This work was supported in part by NSF DMS grants 1211463 (the first two authors), 1211521 and 141877 (the third author), as well as a College of Science of Texas A&M University grant.

The oral cavity is place of 6% of all tumours in dogs, being the sixth most important localization of neoplasias in this specie. The non-odontogenic tumors arise from structures of the oral cavity, except from dental tissue, and they are mostly malignant. Odontogenic tumors are those originated from the dental structures. In the case of tumors of non-odontogenic, will be described the oral papillomatosis, the melanoma, the squamous cell carcinoma, and the fibrosarcoma. Among the odontogenic tumors, the focus will be on the epulides, ameloblastoma, odontoma and dentigerous cysts.

Reincarnation in America: A Brief Historical Overview

Directory of Open Access Journals (Sweden)

Lee Irwin

2017-10-01

Full Text Available American theories of reincarnation have a long and complex history, dating from 1680s to the present. It is the purpose of this paper to highlight the main currents of reincarnation theory in the American context, giving a brief historical survey. Sources surveyed begin with Native American traditions, and then move to immigrant traditions based in Western Esotericism, Christianity, Judaism, missionary Hinduism and Buddhism, Spiritualism, Theosophy, Rosicrucianism, and concludes with more current theoretical influences, based in paranormal science research. The paper demonstrates that current theories of reincarnation are increasingly less dependent upon religious support and increasingly based in direct personal experience, paranormal research, and new therapeutic models. The paper concludes with some reflections on the complexity of reincarnation theory and raises questions concerning the future development of such theory.

Assessing modeled Greenland surface mass balance in the GISS Model E2 and its sensitivity to surface albedo

Science.gov (United States)

Alexander, Patrick; LeGrande, Allegra N.; Koenig, Lora S.; Tedesco, Marco; Moustafa, Samiah E.; Ivanoff, Alvaro; Fischer, Robert P.; Fettweis, Xavier

2016-04-01

The surface mass balance (SMB) of the Greenland Ice Sheet (GrIS) plays an important role in global sea level change. Regional Climate Models (RCMs) such as the Modèle Atmosphérique Régionale (MAR) have been employed at high spatial resolution with relatively complex physics to simulate ice sheet SMB. Global climate models (GCMs) incorporate less sophisticated physical schemes and provide outputs at a lower spatial resolution, but have the advantage of modeling the interaction between different components of the earth's oceans, climate, and land surface at a global scale. Improving the ability of GCMs to represent ice sheet SMB is important for making predictions of future changes in global sea level. With the ultimate goal of improving SMB simulated by the Goddard Institute for Space Studies (GISS) Model E2 GCM, we compare simulated GrIS SMB against the outputs of the MAR model and radar-derived estimates of snow accumulation. In order to reproduce present-day climate variability in the Model E2 simulation, winds are constrained to match the reanalysis datasets used to force MAR at the lateral boundaries. We conduct a preliminary assessment of the sensitivity of the simulated Model E2 SMB to surface albedo, a parameter that is known to strongly influence SMB. Model E2 albedo is set to a fixed value of 0.8 over the entire ice sheet in the initial configuration of the model (control case). We adjust this fixed value in an ensemble of simulations over a range of 0.4 to 0.8 (roughly the range of observed summer GrIS albedo values) to examine the sensitivity of ice-sheet-wide SMB to albedo. We prescribe albedo from the Moderate Resolution Imaging Spectroradiometer (MODIS) MCD43A3 v6 to examine the impact of a more realistic spatial and temporal variations in albedo. An age-dependent snow albedo parameterization is applied, and its impact on SMB relative to observations and the RCM is assessed.

The unique properties of the neutron are being used to investigate problems in chemistry, materials science, physics, engineering and biology. The reactor HIFAR at the Australian Nuclear Science and Technology Organisation research laboratories is the only neutron source in Australia suitable for neutron scattering science. A suite of instruments provides a range of opportunities for the neutron scattering community that extends throughout universities, government and industrial research laboratories. Plans to replace the present research reactor with a modern multi-purpose research reactor are well advanced. The experimental and analysis equipment associated with a modern research reactor will permit the establishment of a national centre for world class neutron science research focussed on the structure and functioning of materials, industrial irradiations and analyses in support of Australian manufacturing, minerals, petrochemical, pharmaceuticals and information science industries. A brief overview will be presented of all the instruments presently available at ANSTO with emphasis on the SANS instrument. This will be followed by a description of the replacement research reactor and its instruments. (author)

Ionic liquids in protein amyloidogenesis: a brief screenshot of the state-of-the-art.

Science.gov (United States)

Pillai, Visakh V S; Benedetto, Antonio

2018-05-03

Ionic liquids (ILs) are a vast class of organic non-aqueous electrolytes whose interaction with biomolecules is receiving great attention for potential applications in bio-nano-technology. Recently, it has been shown that ILs can affect protein amyloidogenesis. Whereas some ILs favour the aggregation of proteins into amyloids, others inhibit their formation. Moreover, ILs can dissolve mature fibrils and restore the protein biochemical function. In this letter, we present a brief state-of-the-art summary of this emerging field that holds the promise of important developments both in basic science and in applications from bio-medicine to material science, and bio-nano-technology. The huge variety of ILs offers a vast playground for future studies and potential applications.

What does "brief" mean? A theoretical critique of the concept of brief therapy from a psychoanalytic viewpoint.

Science.gov (United States)

Migone, Paolo

2014-08-01

The concept of "brief therapy" contains internal contradictions. The techniques suggested by brief therapists are the same techniques that have been discussed historically in debates on theory of technique, both within and without psychoanalysis (e.g., the experiential factor at the center of the Freud-Ferenczi confrontation is also an important aspect of Gestalt therapy). A time limit is the only operational criterion that allows a rigorous definition of brief therapy; without this criterion it is impossible to discriminate between "brief" and simply "good" therapies (i.e., those in which patients are successfully treated in a short time). An important question is why, with a given patient, a therapist should decide, a priori, to terminate a treatment within a set time. Two clinical examples are presented, illustrating the usefulness of Eissler's concept of parameters as a heuristic framework to identify the potentially defensive nature of both "brief" and "long-term" therapy. © 2014 by the American Psychoanalytic Association.

A Unitary-Transformative Nursing Science: From Angst to Appreciation.

Cowling, W Richard

2017-10-01

The discord within nursing regarding the definition of nursing science has created great angst, particularly for those who view nursing science as a body of knowledge derived from theories specific to its unique concerns. The purpose of this brief article is to suggest a perspective and process grounded in appreciation of wholeness that may offer a way forward for proponents of a unitary-transformative nursing science that transcends the discord. This way forward is guided by principles of fostering dissent without contempt, generating a well-imagined future, and garnering appreciatively inspired action for change.

Using Self Organizing Maps to evaluate the NASA GISS AR5 SCM at the ARM SGP Site

Science.gov (United States)

Dong, X.; Kennedy, A. D.; Xi, B.

2010-12-01

Cluster analyses have gained popularity in recent years to establish cloud regimes using satellite and radar cloud data. These regimes can then be used to evaluate climate models or to determine what large-scale or subgrid processes are responsible for cloud formation. An alternative approach is to first classify the meteorological regimes (i.e. synoptic pattern and forcing) and then determine what cloud scenes occur. In this study, a competitive neural network known as the Self Organizing Map (SOM) is used to classify synoptic patterns over the Southern Great Plains (SGP) region to evaluate simulated clouds from the AR5 version of the NASA GISS Model E Single Column Model (SCM). In detail, 54-class SOMs have been developed using North American Regional Reanalysis (NARR) variables averaged to 2x2.5 degree latitude longitude grid boxes for a region of 7x7 grid boxes centered on the ARM SGP site. Variables input into the SOM include mean sea-level pressure and the horizontal wind components, relative humidity, and geopotential height at the 900, 500, and 300 hPa levels. These SOMs are produced for the winter (DJF), spring (MAM), summer (JJA), and fall (SON) seasons during 1999-2001. This synoptic typing will be associated with observed cloud fractions and forcing properties from the ARM SGP site and then used to evaluate simulated clouds from the SCM. SOMs provide a visually intuitive way to understand their classifications because classes are related to each other in a two-dimensional space. In Fig. 1 for example, the reader can easily see for a 54 class SOM during the winter season, classes with higher 300 hPa mean relative humidities are clustered near each other. This allows for the user to identify that there appears to be a relationship between mean 300 hPa RH and high cloud fraction as observed by the ARM SGP site. Figure 1.

Discursive Contextures of Science: Euro/West-Centrism and Science and Technology Studies

Directory of Open Access Journals (Sweden)

Amit Prasad

2016-07-01

Full Text Available Science and Technology Studies (STS by the very act of showing the multiplicity, contingency, and context-dependence of scientific knowledge and practice, provincialized modern science. Postcolonial interventions within STS have pursued this goal even further. Nevertheless, Euro/West-centrism continues to inflect not only scientific practices and lay imaginaries, but also sociological and historical analyses of sciences. In this article, drawing on my own training within STS – first under J.P.S. Uberoi, who was concerned with structuralist analysis of modernity and science, and thereafter under Andy Pickering, when we focused on material agency and temporal emergence and extensively engaged with Actor Network Theory - I emphasize the continuing role of Euro/West-centric discourses in defining the “self” and the “other” and in impacting epistemological and ontological interventions. More broadly, building on a concept of Michael Lynch’s, I call for excavation and analysis of discursive contextures of sciences. In the second section of the article, through a brief analysis of embryonic stem cell therapy in a clinic in Delhi, I show how with shifting transnational landscape of technoscience certain discursive contextures are being “deterritorialized” and left “stuttering.”

Climate response to projected changes in short-lived species under an A1B scenario from 2000-2050 in the GISS climate model

Menon, Surabi; Shindell, Drew T.; Faluvegi, Greg; Bauer, Susanne E.; Koch, Dorothy M.; Unger, Nadine; Menon, Surabi; Miller, Ron L.; Schmidt, Gavin A.; Streets, David G.

We investigate the climate forcing from and response to projected changes in short-lived species and methane under the A1B scenario from 2000-2050 in the GISS climate model. We present a meta-analysis of new simulations of the full evolution of gas and aerosol species and other existing experiments with variations of the same model. The comparison highlights the importance of several physical processes in determining radiative forcing, especially the effect of climate change on stratosphere-troposphere exchange, heterogeneous sulfate-nitrate-dust chemistry, and changes in methane oxidation and natural emissions. However, the impact of these fairly uncertain physical effects is substantially less than the difference between alternative emission scenarios for all short-lived species. The net global mean annual average direct radiative forcing from the short-lived species is .02 W/m{sup 2} or less in our projections, as substantial positive ozone forcing is largely offset by negative aerosol direct forcing. Since aerosol reductions also lead to a reduced indirect effect, the global mean surface temperature warms by {approx}0.07 C by 2030 and {approx}0.13 C by 2050, adding 19% and 17%, respectively, to the warming induced by long-lived greenhouse gases. Regional direct forcings are large, up to 3.8 W/m{sup 2}. The ensemble-mean climate response shows little regional correlation with the spatial pattern of the forcing, however, suggesting that oceanic and atmospheric mixing generally overwhelms the effect of even large localized forcings. Exceptions are the polar regions, where ozone and aerosols may induce substantial seasonal climate changes.

Bajpayee Jaya; Durham, Darcie; Ichkawich, Thomas

2006-01-01

The Glory program is an Earth and Solar science mission designed to broaden science community knowledge of the environment. The causes and effects of global warming have become a concern in recent years and Glory aims to contribute to the knowledge base of the science community. Glory is designed for two functions: one is solar viewing to monitor the total solar irradiance and the other is observing the Earth s atmosphere for aerosol composition. The former is done with an active cavity radiometer, while the latter is accomplished with an aerosol polarimeter sensor to discern atmospheric particles. The Glory program is managed by NASA Goddard Space Flight Center (GSFC) with Orbital Sciences in Dulles, VA as the prime contractor for the spacecraft bus, mission operations, and ground system. This paper will describe some of the more unique features of the Glory program including the integration and testing of the satellite and instruments as well as the science data processing. The spacecraft integration and test approach requires extensive analysis and additional planning to ensure existing components are successfully functioning with the new Glory components. The science mission data analysis requires development of mission unique processing systems and algorithms. Science data analysis and distribution will utilize our national assets at the Goddard Institute for Space Studies (GISS) and the University of Colorado's Laboratory for Atmospheric and Space Physics (LASP). The Satellite was originally designed and built for the Vegetation Canopy Lidar (VCL) mission, which was terminated in the middle of integration and testing due to payload development issues. The bus was then placed in secure storage in 2001 and removed from an environmentally controlled container in late 2003 to be refurbished to meet the Glory program requirements. Functional testing of all the components was done as a system at the start of the program, very different from a traditional program

Clarys, Jan Pieter; Alewaeters, Katrien

Both the history of biolocomotion (later to become motion analysis/biomechanics) and of electrology (later kinesiological electromyography) are to be traced back to approximatively the same period in the second half of the seventeenth century. The major contributors to these emergent sciences were Swammerdam in 1658 and Borelli in 1680. Some 150 years later, electrophysiological methods were derived and motion-cinephotography was developed from their pioneering work. Subsequently, use was made of motion analysis by means of cinephotography, forming a basis for biomechanics. The work of Marey in 1873 in particular stimulated the multidisciplinary study of human activity, providing models for contemporary sports scientists working in applied settings. The link between theory and practice in motion sciences and the multidisciplinary model of Marey were the motive and the example for establishing the Working Group of Biomechanics in the 1960s. This body has gone through a series of progressive developments, culminating in the approval of the World Commission of Science and Sports as a service group of the International Council for Sport Science and Physical Education (recognized by UNESCO).

The Brazilian Soil Science Society (SBCS) is one of the oldest scientific societies in Brazil. It was created in October 1947 during the 1st Brazilian Meeting of Soil Science held at the headquarters of the Agricultural Chemistry Institute of Rio de Janeiro, at present the Soils Institute of the Brazilian Agricultural Research Centre. Its origin lies within the Interamerican Conference of Agriculture, Caracas, 1945, the 2nd Pan American Congress of Mining and Geology, Petropolis, Rio de Janeiro, 1946 and the 5th Brazilian Congress of Chemistry, Porto Alegre, 1947. Its first president was Álvaro Barcelos Fagundes, who was the only Brazilian participant at the 1st International Congress of Soil Science and Transcontinental Excursion held in United States of America, in 1927. At that time he was engaged in research work at the New Jersey Agricultural Experiment Station, at the Rutgers University where he did a doctorate under the guidance of Professor Selman Waksman. The society started with 47 members and presently has nearly 900 members. In its first phase the Brazilian Soil Science Society was housed at the Agricultural Chemistry Institute in Rio de Janeiro and its main activity was the biannual Brazilian Congress of Soil Science. In 1975 its headquarters moved to the Agronomic Institute of Campinas with the creation of its executive board and the start of publication of the Brazilian Journal of Soil Science (1977) as well as the society bulletin (1976). In 1997 its executive office moved to the Soils Department at the Federal University of Viçosa. Nowadays it has a structure similar to the one from the IUSS: the society is organized in four divisions (Soil in space and time, Soils properties and processes, Soil use and management and Soil, environment and society) which encompass 14 technical commissions and eight State or Regional nuclei. The Brazilian Congresses of Soil Science happen without interruption since 1947. The first one had had 72 participants that

The experiments carried out during these flights included astrophysics, solar physics, plasma physics, atmospheric science, Earth observations, and a wide range of microgravity experiments in life sciences, biotechnology, materials science, and fluid physics which includes combustion and critical point phenomena. In all, some 764 experiments were conducted by investigators from the U.S., Europe, and Japan. The purpose of this Spacelab Science Results Study is to document the contributions made in each of the major research areas by giving a brief synopsis of the more significant experiments and an extensive list of the publications that were produced. We have also endeavored to show how these results impacted the existing body of knowledge, where they have spawned new fields, and if appropriate, where the knowledge they produced has been applied.

A critical aspect of teacher education is gaining pedagogical content knowledge of how to teach science for conceptual understanding. Given the time limitations of college methods courses, it is difficult to touch on more than a fraction of the science topics potentially taught across grades K-8, particularly in the context of relevant pedagogies. This research and development work centers on constructing a formative assessment resource to help expose pre-service teachers to a greater number of science topics within teaching episodes using various modes of instruction. To this end, 100 problem-based, science pedagogy assessment items were developed via expert group discussions and pilot testing. Each item contains a classroom vignette followed by response choices carefully crafted to include four basic pedagogies (didactic direct, active direct, guided inquiry, and open inquiry). The brief but numerous items allow a substantial increase in the number of science topics that pre-service students may consider. The intention is that students and teachers will be able to share and discuss particular responses to individual items, or else record their responses to collections of items and thereby create a snapshot profile of their teaching orientations. Subsets of items were piloted with students in pre-service science methods courses, and the quantitative results of student responses were spread sufficiently to suggest that the items can be effective for their intended purpose.

Showstack, Randy

2009-06-01

“It is essential that world leaders agree on emissions reductions needed to combat negative consequences of anthropogenic climate change,” national science academies from 13 countries declared in a joint statement issued on 11 June. The statement, issued by the academies of the G8 countries—including England, France, Russia, and the United States—and five other countries (Brazil, China, India, Mexico, and South Africa), came in advance of a G8 meeting in Italy in July and prior to United Nations Framework Convention on Climate Change (UNFCCC) negotiations in Denmark in December. “The G8+5 should lead the transition to an energy-efficient and low-carbon world economy, and foster innovation and research and development for both mitigation and adaptation technologies,” the statement noted. The academies urged governments to agree at the UNFCCC negotiations to adopt a long-term global goal and short-term emissions reduction targets so that by 2050 global emissions would be reduced by about 50% from 1990 levels.

The northern annular mode in summer and its relation to solar activity variations in the GISS ModelE

Science.gov (United States)

Lee, Jae N.; Hameed, Sultan; Shindell, Drew T.

2008-03-01

The northern annular mode (NAM) has been successfully used in several studies to understand the variability of the winter atmosphere and its modulation by solar activity. The variability of summer circulation can also be described by the leading empirical orthogonal function (EOF) of geopotential heights. We compare the annular modes of the summer geopotential heights in the northern hemisphere stratosphere and troposphere in the Goddard Institute for Space Studies (GISS) ModelE with those in the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) reanalysis. In the stratosphere, the summer NAM obtained from NCEP/NCAR reanalysis as well as from the ModelE simulations has the same sign throughout the northern hemisphere, but shows greater variability at low latitudes. The patterns in both analyses are consistent with the interpretation that low NAM conditions represent an enhancement of the seasonal difference between the summer and the annual averages of geopotential height, temperature and velocity distributions, while the reverse holds for high NAM conditions. Composite analysis of high and low NAM cases in both model and observation suggests that the summer stratosphere is more "summer-like" when the solar activity is near a maximum. This means that the zonal easterly wind flow is stronger and the temperature is higher than normal. Thus increased irradiance favors a low summer NAM. A quantitative comparison of the anti-correlation between the NAM and the solar forcing is presented in the model and in the observation, both of which show lower/higher NAM index in solar maximum/minimum conditions. The temperature fluctuations in simulated solar minimum conditions are greater than in solar maximum throughout the summer stratosphere. The summer NAM in the troposphere obtained from NCEP/NCAR reanalysis has a dipolar zonal structure with maximum variability over the Asian monsoon region. The corresponding EOF in ModelE has

Using long-term ARM observations to evaluate Arctic mixed-phased cloud representation in the GISS ModelE GCM

The presence of supercooled liquid in clouds affects surface radiative and hydrological budgets, especially at high latitudes. Capturing these effects is crucial to properly quantifying climate sensitivity. Currently, a number of CGMs disagree on the distribution of cloud phase. Adding to the challenge is a general lack of observations on the continuum of clouds, from high to low-level and from warm to cold. In the current study, continuous observations from 2011 to 2014 are used to evaluate all clouds produced by the GISS ModelE GCM over the ARM North Slope of Alaska site. The International Satellite Cloud Climatology Project (ISCCP) Global Weather State (GWS) approach reveals that fair-weather (GWS 7, 32% occurrence rate), as well as mid-level storm related (GWS 5, 28%) and polar (GWS 4, 14%) clouds, dominate the large-scale cloud patterns at this high latitude site. At higher spatial and temporal resolutions, ground-based cloud radar observations reveal a majority of single layer cloud vertical structures (CVS). While clear sky and low-level clouds dominate (each with 30% occurrence rate) a fair amount of shallow ( 10%) to deep ( 5%) convection are observed. Cloud radar Doppler spectra are used along with depolarization lidar observations in a neural network approach to detect the presence, layering and inhomogeneity of supercooled liquid layers. Preliminary analyses indicate that most of the low-level clouds sampled contain one or more supercooled liquid layers. Furthermore, the relationship between CVS and the presence of supercooled liquid is established, as is the relationship between the presence of supercool liquid and precipitation susceptibility. Two approaches are explored to bridge the gap between large footprint GCM simulations and high-resolution ground-based observations. The first approach consists of comparing model output and ground-based observations that exhibit the same column CVS type (i.e. same cloud depth, height and layering

After the accident of the Fukushima Daiichi Nuclear Power Plant, enormous amount of waste contaminated by radioactive cesium has been produced. Burned ash that contained radiocesium ( 137 Cs) more than 8,000 Bq/kg will be stored at the not-yet-located final deposit. Until the final deposit is finally constructed, however, the radioactive ash should be stored safely at temporal deposits. Inhabitants briefing sessions for locating the temporal deposits are held at many places in the east Japan. But, they met difficulty in establishing smooth communication between citizens and the administrations. In this paper, I classify the questions arose from citizens at the inhabitants briefing session at Tokatsu area, Chiba prefecture, and discuss what role could scientists and science communicators play at this session. In addition, I classified the voices of inhabitants reported in the newspapers and discuss the media bias. (author)

A new direction in mathematics for materials science

CERN Document Server

Ikeda, Susumu

2015-01-01

This book is the first volume of the SpringerBriefs in the Mathematics of Materials and provides a comprehensive guide to the interaction of mathematics with materials science. The anterior part of the book describes a selected history of materials science as well as the interaction between mathematics and materials in history. The emergence of materials science was itself a result of an interdisciplinary movement in the 1950s and 1960s. Materials science was formed by the integration of metallurgy, polymer science, ceramics, solid state physics, and related disciplines. We believe that such historical background helps readers to understand the importance of interdisciplinary interaction such as mathematics–materials science collaboration. The middle part of the book describes mathematical ideas and methods that can be applied to materials problems and introduces some examples of specific studies—for example, computational homology applied to structural analysis of glassy materials, stochastic models for ...

2012-09-01

Policy approaches are one of the most promising population-based means of addressing the epidemic of obesity in the U.S., especially as they create supportive environments for healthy living. Policy briefs can be an effective means of disseminating research information to inform obesity prevention efforts; however, they are often ineffective because of length, density, and inaccessibility. The purposes of this project were to identify a collection of obesity-related policy briefs, analyze the content, and make recommendations for model policy briefs. In 2010, online searching strategies were developed with criteria that included a primary topical focus on obesity, written between 2000 and 2010, targeting any population age group, including a policy-change message, and being readily available online. The research team developed a coding tool and used it to analyze briefs. A subsample of the briefs was used for further analysis on dissemination. Analyses were conducted on 100 briefs. Most (72%) were developed between 2005 and 2010; the average length was five pages. The majority had no tables, few figures, and only 36% included photos. The average reading level was high. A lack of monitoring or evaluating dissemination efforts prevailed. Policy briefs represent an effective, often-preferred, potent tool for public health practitioners and researchers to communicate information to policymakers. Recommendations include presenting information clearly, using a concise format, including design elements, noting reference and contact information, employing active and targeted dissemination efforts, and conducting evaluation.

Psychoanalysis, science and the seductive theory of Karl Popper.

Science.gov (United States)

Grant, Don C; Harari, Edwin

2005-06-01

To present a critique of the ideas of Karl Popper, the philosopher of science, whose depiction of psychoanalysis as a pseudoscience is often used to justify attacks on psychoanalysis. Published sources are used to provide a brief intellectual biography of Popper, a summary of his concept of science and a summary of criticisms of Popper's view of science. His depiction of psychoanalysis and Freud's reply are presented. Clinical, experimental and neurobiological research which refutes Popper's view is summarized. There is a vast scholarly published work critical of Popper's falsifiability criterion of science. Less recognized is Popper's misunderstanding and misrepresentation of psychoanalysis; his argument against it is logically flawed and empirically false. Even if Popper's theory of science is accepted, there is considerable clinical, experimental and neurobiological research in psychoanalysis which meets Popper's criterion of science. Attacks on psychoanalysis based on Popper's theory of science are ill-founded and reflect inadequate scholarship.

Atomic and molecular science: progress and opportunities

International Nuclear Information System (INIS)

Mathur, D.

2000-01-01

In the contemporary scenario, atomic, molecular and optical (AMO) science focuses on the physical and chemical properties of the common building blocks of matter - atoms, molecules and light. The main characteristic of AMO science is that it is both an intellectually stimulating fundamental science and a powerful enabling science that supports an increasing number of other important areas of science and technology. In brief, the fundamental interests in atoms, molecules and clusters (as well as their ions) include studies of their structure and properties, their optical interactions, collisional properties, including quantum state-resolved studies, and interactions with external fields, solids and surfaces. Fundamental aspects of present-day optical sciences include studies of laser spectroscopy, nonlinear optics, quantum optics, optical interactions with condensed matter, ultrafast optics and coherent light sources. The enabling aspect of AMO science derives from efforts to control atoms, molecules, clusters, charged particles and light more precisely, to accurately to determine, experimentally and theoretically, their properties, and to invent new, methods of generating light with tailor-made properties

O' Brien, Janese C. [Iowa State Univ., Ames, IA (United States)

2000-09-21

Likedlessentid sciences, anal~cd chetis~continues toreinvent itself. Moving beyond its traditional roles of identification and quantification, analytical chemistry is now expanding its frontiers into areas previously reserved to other disciplines. This work describes several research efforts that lie at the new interfaces between analytical chemistry and two of these disciplines, namely materials science and biology. In the materials science realm, the search for new materials that may have useful or unique chromatographic properties motivated the synthesis and characterization of electrically conductive sol-gels. In the biology realm, the search for new surface fabrication schemes that would permit or even improve the detection of specific biological reactions motivated the design of miniaturized biological arrays. Collectively, this work represents some of analytical chemistry’s newest forays into these disciplines. The introduction section to this dissertation provides a literature review on several of the key aspects of this work. In advance of the materials science discussion, a brief introduction into electrochemically-modulated liquid chromatography (EMLC) and sol-gel chemistry is provided. In advance of the biological discussions, brief overviews of scanning force microscopy (SFM) and the oxidative chemistry used to construct our biological arrays are provided. This section is followed by four chapters, each of which is presented as a separate manuscript, and focuses on work that describes some of our cross-disciplinary efforts within materials science and biology. This dissertation concludes with a general summary and future prospectus.

Simulations of the Mid-Pliocene Warm Period Using Two Versions of the NASA-GISS ModelE2-R Coupled Model

Science.gov (United States)

Chandler, M. A.; Sohl, L. E.; Jonas, J. A.; Dowsett, H. J.; Kelley, M.

2013-01-01

The mid-Pliocene Warm Period (mPWP) bears many similarities to aspects of future global warming as projected by the Intergovernmental Panel on Climate Change (IPCC, 2007). Both marine and terrestrial data point to high-latitude temperature amplification, including large decreases in sea ice and land ice, as well as expansion of warmer climate biomes into higher latitudes. Here we present our most recent simulations of the mid-Pliocene climate using the CMIP5 version of the NASAGISS Earth System Model (ModelE2-R). We describe the substantial impact associated with a recent correction made in the implementation of the Gent-McWilliams ocean mixing scheme (GM), which has a large effect on the simulation of ocean surface temperatures, particularly in the North Atlantic Ocean. The effect of this correction on the Pliocene climate results would not have been easily determined from examining its impact on the preindustrial runs alone, a useful demonstration of how the consequences of code improvements as seen in modern climate control runs do not necessarily portend the impacts in extreme climates.Both the GM-corrected and GM-uncorrected simulations were contributed to the Pliocene Model Intercomparison Project (PlioMIP) Experiment 2. Many findings presented here corroborate results from other PlioMIP multi-model ensemble papers, but we also emphasize features in the ModelE2-R simulations that are unlike the ensemble means. The corrected version yields results that more closely resemble the ocean core data as well as the PRISM3D reconstructions of the mid-Pliocene, especially the dramatic warming in the North Atlantic and Greenland-Iceland-Norwegian Sea, which in the new simulation appears to be far more realistic than previously found with older versions of the GISS model. Our belief is that continued development of key physical routines in the atmospheric model, along with higher resolution and recent corrections to mixing parameterisations in the ocean model, have led

NEWS: Why choose science?

Science.gov (United States)

2000-05-01

National concerns over the uptake of science subjects and an analysis of how school science departments together with careers programmes influence students' subject choices feature in a recent report from the UK's National Institute for Careers Education and Counselling. It points out that decisions on science subjects are taken very early in pupils' education, often well before the implications of those choices can be clearly understood. If pupils are to be encouraged to keep science options open, then both science teachers and careers advisers have important roles to play. Physics is in fact singled out in the report's recommendations as in need of special attention, due to its perceived difficulty both within the double-award science course and also at A-level. The lack of qualified teachers in physics is noted as a problem for schools and the many initiatives to address these issues should be encouraged according to the report, but within an overall high-profile and well funded national strategy for developing science education in schools. The report also notes that science teachers do not feel able to keep up with career information, whilst few careers advisers have a science background and have little opportunity to build up their knowledge of science syllabuses or of science and engineering careers. More contact between both types of specialist is naturally advocated. Copies of the full report, Choosing Science at 16 by Mary Munro and David Elsom, are available from NICEC, Sheraton House, Castle Park, Cambridge CB3 0AX on receipt of an A4 stamped (70p) addressed envelope. A NICEC briefing summary is also available from the same address (20p stamp required).

This technology brief on gas-fired power is part of a series produced by the IEA called the energy technology data source (E-Tech-DS). The E-Tech-DS series consists of a number of 5-10 page technology briefs similar to the IEA Energy Technology Essentials. Based on the data collected for the models that the Energy Technology Systems Analysis Programme (ETSAP) is known for, ETSAP also prepares technology briefs, called E-TechDS. The E-TechDS briefs are standardized presentations of basic information (process, status, performance, costs, potential, and barriers) for key energy technology clusters. Each brief includes an overview of the technology, charts and graphs, and a summary data table, and usually ending with some key references and further information. The E TechDS briefs are intended to offer essential, reliable and quantitative information to energy analysts, experts, policymakers, investors and media from both developed and developing countries. This specific brief focuses on the state of combined-cycle gas turbines (CCGT). CCGT's have become the technology of choice for new gas-fired power plants since the 1990's.

The borderlands between science and philosophy: an introduction.

Science.gov (United States)

Pigliucci, Massimo

2008-03-01

Science and philosophy have a very long history, dating back at least to the 16th and 17th centuries, when the first scientist-philosophers, such as Bacon, Galilei, and Newton, were beginning the process of turning natural philosophy into science. Contemporary relationships between the two fields are still to some extent marked by the distrust that maintains the divide between the so-called "two cultures." An increasing number of philosophers, however, are making conceptual contributions to sciences ranging from quantum mechanics to evolutionary biology, and a few scientists are conducting research relevant to classically philosophical fields of inquiry, such as consciousness and moral decision-making. This article will introduce readers to the borderlands between science and philosophy, beginning with a brief description of what philosophy of science is about, and including a discussion of how the two disciplines can fruitfully interact not only at the level of scholarship, but also when it comes to controversies surrounding public understanding of science.

An important and substantial area of technical work in which noncontact temperature measurement (NCTM) is desired is that involving combustion process research. In the planning for this workshop, it was hoped that W. Serignano would provide a briefing regarding the experimental requirements for thermal measurements to support such research. The particular features of thermal measurement requirements included those describing the timeline for combustion experiments, the requirements for thermal control and diagnostics of temperature and other related thermal measurements and the criticality to the involved science to parametric features of measurement capability including precision, repeatability, stability, and resolution. In addition, it was hoped that definitions could be provided which characterize the needs for concurrent imaging as it relates to science observations during the conduct of experimentation.

NASA's Earth Science Enterprise: Future Science Missions, Objectives and Challenges

Habib, Shahid

1998-01-01

NASA has been actively involved in studying the planet Earth and its changing environment for well over thirty years. Within the last decade, NASA's Earth Science Enterprise has become a major observational and scientific element of the U.S. Global Change Research Program. NASA's Earth Science Enterprise management has developed a comprehensive observation-based research program addressing all the critical science questions that will take us into the next century. Furthermore, the entire program is being mapped to answer five Science Themes (1) land-cover and land-use change research (2) seasonal-to-interannual climate variability and prediction (3) natural hazards research and applications (4) long-term climate-natural variability and change research and (5) atmospheric ozone research. Now the emergence of newer technologies on the horizon and at the same time continuously declining budget environment has lead to an effort to refocus the Earth Science Enterprise activities. The intent is not to compromise the overall scientific goals, but rather strengthen them by enabling challenging detection, computational and space flight technologies those have not been practically feasible to date. NASA is planning faster, cost effective and relatively smaller missions to continue the science observations from space for the next decade. At the same time, there is a growing interest in the world in the remote sensing area which will allow NASA to take advantage of this by building strong coalitions with a number of international partners. The focus of this presentation is to provide a comprehensive look at the NASA's Earth Science Enterprise in terms of its brief history, scientific objectives, organization, activities and future direction.

Climate is critical. Climate variability affects us all; Climate Change is a burning issue. Droughts, floods, other extreme events, and Global Warming's effects on these and problems such as sea-level rise and ecosystem disruption threaten lives. Citizens must be informed to make decisions concerning climate such as "business as usual" vs. mitigating emissions to keep warming within bounds. Medgar Evers undergraduates aid NASA research while learning climate science and developing computer&math skills. To make useful predictions we must realistically model each component of the climate system, including the ocean, whose critical role includes transporting&storing heat and dissolved CO2. We need physically based parameterizations of key ocean processes that can't be put explicitly in a global climate model, e.g. vertical&lateral mixing. The NASA-GISS turbulence group uses theory to model mixing including: 1) a comprehensive scheme for small scale vertical mixing, including convection&shear, internal waves & double-diffusion, and bottom tides 2) a new parameterization for the lateral&vertical mixing by mesoscale eddies. For better understanding we write our own programs. To assess the modelling MATLAB programs visualize and calculate statistics, including means, standard deviations and correlations, on NASA-GISS OGCM output with different mixing schemes and help us study drift from observations. We also try to upgrade the schemes, e.g. the bottom tidal mixing parameterizations' roughness, calculated from high resolution topographic data using Gaussian weighting functions with cut-offs. We study the effects of their parameters to improve them. A FORTRAN program extracts topography data subsets of manageable size for a MATLAB program, tested on idealized cases, to visualize&calculate roughness on. Students are introduced to modeling a complex system, gain a deeper appreciation of climate science, programming skills and familiarity with MATLAB, while furthering climate

Computational methods and perspectives can transform the history of science by enabling the pursuit of novel types of questions, dramatically expanding the scale of analysis (geographically and temporally), and offering novel forms of publication that greatly enhance access and transparency. This essay presents a brief summary of a computational research system for the history of science, discussing its implications for research, education, and publication practices and its connections to the open-access movement and similar transformations in the natural and social sciences that emphasize big data. It also argues that computational approaches help to reconnect the history of science to individual scientific disciplines.

Physical experience enhances science learning.

Kontra, Carly; Lyons, Daniel J; Fischer, Susan M; Beilock, Sian L

2015-06-01

Three laboratory experiments involving students' behavior and brain imaging and one randomized field experiment in a college physics class explored the importance of physical experience in science learning. We reasoned that students' understanding of science concepts such as torque and angular momentum is aided by activation of sensorimotor brain systems that add kinetic detail and meaning to students' thinking. We tested whether physical experience with angular momentum increases involvement of sensorimotor brain systems during students' subsequent reasoning and whether this involvement aids their understanding. The physical experience, a brief exposure to forces associated with angular momentum, significantly improved quiz scores. Moreover, improved performance was explained by activation of sensorimotor brain regions when students later reasoned about angular momentum. This finding specifies a mechanism underlying the value of physical experience in science education and leads the way for classroom practices in which experience with the physical world is an integral part of learning. © The Author(s) 2015.

Big Data and Intellectual Property Rights in the Health and Life Sciences

DEFF Research Database (Denmark)

Minssen, Timo

The vast prospects of Big Data and the shift to more “personalized”, “open” and “transparent” innovation models highlight the importance of an effective governance, regulation and stimulation of high-quality data-uses in the health and life sciences. Intellectual Property Rights (IPRs) and related...... rights come into play when research is translated into safe and efficient “real world” uses. While the need of recalibrating IPRs to fully support Big Data advances is being intensely debated among multiple stakeholders, there seems to be much confusion about the availability of IPRs and their legal...... effects. In this very brief presentation I intend to provide a very brief overview on the most relevant IPRs for data-based life science research. Realizing that the choice of how to address, use and interact with IPRs differs among various areas of applications, I also intend to sketch out and discuss...

Mangel, Marc

2016-12-20

I provide a brief review of the origins of the International Convention on the Regulation of Whaling and the failure to successfully regulate whaling that led to the commercial moratorium in 1986. I then describe the Japanese Whale Research Programs Under Special Permit in the Antarctica (JARPA I, JARPA II) and the origins of the case Whaling in the Antarctic (Australia v. Japan: New Zealand Intervening) in the International Court of Justice. I explain that the International Court of Justice chose to conduct an objective review of JARPA II, the standard that it used for the review, and the pathway that it took to adjudicate the case without providing a definition of science to be used in international law. I conclude with a brief discussion of the implications of the Judgment for the International Convention on the Regulation of Whaling, and the International Whaling Commission in particular, for other international treaties, and for the interaction of science and law more generally.

[Philosophy of science for psychiatric practice].

Science.gov (United States)

Ralston, A S G

2010-01-01

The prevailing view is that psychiatry has its roots in two separate methodologies: the natural sciences and the social sciences. It is assumed that these are separate domains, each with its own way of knowing. Psychiatric and psychological theories are based mainly on one or other of these two types of science; this leads to a ongoing dualism in psychiatry, which some people regard as problematical. This article aims to make a methodological contribution to the scientific and philosophical foundations of psychiatry. This philosophical and theoretical dichotomy is criticized in this article in the light of recent developments in the philosophy of science, and two methods are introduced which offer an alternative analysis: values-based practice and actor-network theory. Brief examples are given which demonstrate that a combination of these two methods can be productive for psychiatry. Values-based practice and actor-network theory provide a way of resolving the stalemate in the conflict between the physical sciences and the sciences of the mind, a conflict that is dominated by professionals. In addition these two new methods empower the professionals by not deriving legitimacy from the false image of a dichotomous science, but from a normative sense of professionalism.

My brief history

CERN Document Server

Hawking, Stephen

2013-01-01

My Brief History recounts Stephen Hawking’s improbable journey, from his postwar London boyhood to his years of international acclaim and celebrity. Lavishly illustrated with rarely seen photographs, this concise, witty, and candid account introduces readers to a Hawking rarely glimpsed in previous books: the inquisitive schoolboy whose classmates nicknamed him Einstein; the jokester who once placed a bet with a colleague over the existence of a particular black hole; and the young husband and father struggling to gain a foothold in the world of physics and cosmology. Writing with characteristic humility and humor, Hawking opens up about the challenges that confronted him following his diagnosis of ALS at age twenty-one. Tracing his development as a thinker, he explains how the prospect of an early death urged him onward through numerous intellectual breakthroughs, and talks about the genesis of his masterpiece A Brief History of Time—one of the iconic books of the twentieth century.

Pre-surgery briefings and safety climate in the operating theatre.

Allard, Jon; Bleakley, Alan; Hobbs, Adrian; Coombes, Lee

2011-08-01

In 2008, the WHO produced a surgical safety checklist against a background of a poor patient safety record in operating theatres. Formal team briefings are now standard practice in high-risk settings such as the aviation industry and improve safety, but are resisted in surgery. Research evidence is needed to persuade the surgical workforce to adopt safety procedures such as briefings. To investigate whether exposure to pre-surgery briefings is related to perception of safety climate. Three Safety Attitude Questionnaires, completed by operating theatre staff in 2003, 2004 and 2006, were used to evaluate the effects of an educational intervention introducing pre-surgery briefings. Individual practitioners who agree with the statement 'briefings are common in the operating theatre' also report a better 'safety climate' in operating theatres. The study reports a powerful link between briefing practices and attitudes towards safety. Findings build on previous work by reporting on the relationship between briefings and safety climate within a 4-year period. Briefings, however, remain difficult to establish in local contexts without appropriate team-based patient safety education. Success in establishing a safety culture, with associated practices, may depend on first establishing unidirectional, positive change in attitudes to create a safety climate.

To analyze if an iPad-based patient briefing can serve as a digital alternative to conventional documentations prior to radiological examinations. One hundred one patients referred for routine MRI were randomized into two groups, who underwent iPad-based and classic written briefing in opposite order. For each briefing completion time, completeness and correctness were noted. Patient's knowledge about the content of either briefing modality was subsequently tested. The influence of patient-related factors on the performance of the electronic briefing (EB) was analyzed. Finally, the patient's subjective impression of the EB was assessed. The mean durations were 4.4 ± 2.2 min for EB and 1.7 ± 1.3 min for the classic briefing (p iPad briefings were returned entirely filled out, whereas 11 % of the classic forms were returned with missing data. No significant differences in memorization of the briefing's information were objectified. There was a positive correlation between the duration of EB and age (r = 0.53; p iPads transfers the information for the patients equally well compared to the classic written approach. Although iPad briefing took patients longer to perform, the majority would prefer it to written consent briefings in the future. Nevertheless, measures have to be undertaken to improve the overall acceptance and performance.

Teaching the Ethical Aspects of Environmental Science

Palinkas, C. M.

2014-12-01

Environmental and societal issues are often inherently linked, especially in coastal and estuarine environments, and science and social values must often be balanced in ecosystem management and decision-making. A new seminar course has been developed for the Marine Estuarine and Environmental Science (MEES) graduate program, an inter-institutional program within the University System of Maryland, to examine these issues. This 1-credit course, offered for the first time in Spring 2015, takes a complex systems perspective on major environmental and societal challenges to examine these linked issues in a variety of contexts. After a brief introduction to the emerging field of "geoethics," students develop a list of issues to examine throughout the seminar. Example topics could include fracking, offshore wind technology, dam removal, and iron fertilization, among others. A case-study approach is taken, with each class meeting focusing on one issue. For each case study, students are asked to 1) identify relevant scientific principles and major knowledge gaps, 2) predict potential outcomes, 3) identify stakeholders and likely viewpoints, and 4) construct communication plans to disseminate findings to these stakeholders. At the end of the semester, students give a brief presentation of the ethical aspects of their own research topics.

The effectiveness of an evidence-based health care intervention depends on it being delivered consistently to appropriate patients. Brief alcohol intervention is known to be effective at reducing excessive drinking and its concomitant health and social problems. However, a recent implementation trial reported partial delivery of brief alcohol intervention by general practitioners (GPs) which is likely to have reduced its impact. To investigate patient-practitioner characteristics influencing brief alcohol intervention in primary care. Cross-sectional analysis of 12,814 completed Alcohol Use Disorders Identification Test (AUDIT) screening questionnaires. Eighty-four GPs who had implemented a brief alcohol intervention programme in a previous trial based in the Northeast of England. GPs were requested to screen all adults (aged over 16 years) presenting to their surgery and follow a structured protocol to give a brief intervention (five minutes of advice plus an information booklet) to all 'risk' drinkers. Anonymized carbon copies of the screening questionnaire were collected from all practices after a three-month implementation period. Although AUDIT identified 4080 'risk' drinkers, only 2043 (50%) received brief intervention. Risk drinkers that were most likely to receive brief intervention were males (58%), unemployed (61%), and technically-trained patients (55%). Risk drinkers that were least likely to receive brief intervention were females (44%), students (38%), and university educated patients (46%). Logistic regression modelling showed that patients' risk status was the most influential predictor of brief intervention. Also, GPs' experience of relevant training and longer average practice consultations predicted brief intervention. However, personal characteristics relating to patients and GPs also predicted brief intervention in routine practice. Interpersonal factors relating to patients and practitioners contributed to the selective provision of brief

Role of radiotracer in animal science

International Nuclear Information System (INIS)

Sivaprasad, N.

2015-01-01

Radiotracers have been used as radiopharmaceuticals for diagnosis and treatment of animal diseases in cattle and pet animals. In fact the veterinary nuclear medicine based on radiotracer as radiopharmaceuticals is established medical technique for functional studies and imaging of vital organs such as heart, lung, brain, spleen, liver, kidney etc for diagnosis as well as treatment of diseases such as cancers in animal. Besides, radiation from radioisotopes has been in use for radiation therapy of cancers in animals. The nuclear imaging using positron emitting radiotracer is gaining importance in the evolution of drug in small animals. In this respect, small animals have also contributed significantly in the development of radiopharmaceuticals particularly for biodistribution and bioscan studies. In fact, the quality control of radiopharmaceuticals in animals to test the safety is a mandatory requirement in the production of radiopharmaceuticals. In brief the animal science has contributed in various areas and facets of radiotracer techniques and its application vice versa the radiotracer techniques have contributed towards the progress of animal science. The animal science in combination with radiotracer has also contributed to the progress of other basic and applied sciences. Thus there exists a bond between radiotracer techniques and animal science. Some aspects of mutual dependence of animal science and radiotracer are elaborated

Kincaid, Russell

2010-03-01

From 1995-2007, U.S. science students in grade four scored higher than the scaled TIMSS average, but their scores did not improve over this time. Moreover, in the area of physical science, the U.S. scored significantly lower than several Asian countries, as well as Russia, England, and Latvia (TIMSS). Methods to enhance student achievement in science are still being sought. An approach to utilizing playground equipment as a teaching tool for a variety of physics concepts was developed as a physical science teaching method. This program established an appropriate set of experiments, coordinated the effort with local school districts, and implemented a brief pilot study to test the teaching methodology. The program assigned undergraduate middle school science education majors to teach small groups of fourth grade students. The experimental group used the newly developed ``Playground Physics'' methodology while the control group used traditional approaches. Follow up activities will include an expansion of the duration and the scope of the program.

A BRIEF HISTORY OF THE INTRODUCTION OF MODERN SCIENCE TO PORTUGAL DURING THE 18th CENTURY

Directory of Open Access Journals (Sweden)

TERESA CASTELÃO-LAWLESS

2016-05-01

Full Text Available The focus of this article is on the role played by members of the Society of Jesus, the Order of the Oratorians, and the Jewish community in the introduction of Modern science in Portugal during the 18th century. The record of their publications prove, contrary to common stereotypes on the permanent conflict between science and religion, that they all embraced Modern, anti-Aristotelian, natural philosophy fairly equally and unreservedly. The rhetoric they used in manuscript Dedications to prospective patrons also show that they were actively engaged in shifting Modern science from a context of private consumption to one of public circulation. I acknowledgethat the dissemination of Modern science in Portugal during the 1700’s was slow and protracted. This phenomenon, however, was not, as typically argued, caused by scientific conservatism on the part of the religious Orders, or the ill will of patrons of the sciences, but by the political motives of enlightened despots João V, José I and his Prime-Minister the Marquis of Pombal.

Is psychological science a-cultural?

Science.gov (United States)

Gone, Joseph P

2011-07-01

The history of psychological science, as it has intersected with ethnoracial, cultural, and other marginalized domains of group difference, is replete with disinterest, dismissal, or denigration of these diverse forms of psychological experience. This has led some to wonder whether psychological science is a-cultural, or even anti-cultural in orientation. Assessment of this provocative proposition first requires exploration of three composite questions: (1) What is culture?, (2) What is science?, and (3) What is psychological science? Based on brief consideration of these composite questions--which are remarkably complex in their own right--I argue that psychological science is not, has never been, and indeed cannot in principle be a-cultural. Instead, like all forms of knowing, psychological science emerges at particular historical moments to achieve particular goals that are motivated by particular interests. Throughout much of the history of psychological science, these goals and interests were tied to ideologically suspect agendas that contemporary psychologists are right to repudiate. The interesting question becomes whether psychology's knowledge practices can be disentangled from this earlier ideological contamination to furnish the discipline with viable methods. I propose that psychological science can in fact be so disentangled; nevertheless, the resulting methods are never adopted or deployed outside of culturally constituted interests, objectives, and motivations, thereby requiring ongoing critical engagement with the subtexts of disciplinary knowledge production. In fact, there seem to be important ways in which psychology's scientific aspirations hobble disciplinary inquiry into the human condition that has motivated multicultural psychologists to consider alternative paradigms of inquiry.

Early Science Instruction and Academic Language Development Can Go Hand in Hand. The Promising Effects of a Low-Intensity Teacher-Focused Intervention

Henrichs, Lotte F.; Leseman, Paul P. M.

2014-11-01

Early science instruction is important in order to lay a firm basis for learning scientific concepts and scientific thinking. In addition, young children enjoy science. However, science plays only a minor role in the kindergarten curriculum. It has been reported that teachers feel they need to prioritize language and literacy practices over science. In this paper, we investigate whether science lessons might be integrated with learning the language functional for school: academic language. The occurrence of scientific reasoning and sophisticated vocabulary in brief science lessons with 5-year-olds is evaluated. The aim of the study was twofold: first, to explore the nature of kindergarten science discourse without any researcher directions (pre-intervention observation). Second, in a randomized control trial, we evaluated the effect on science discourse of a brief teacher training session focused on academic language awareness. The science lessons focussed on air pressure and mirror reflection. Analyses showed that teachers from the intervention group increased their use of scientific reasoning and of domain-specific academic words in their science discourse, compared to the control group. For the use of general academic words and for lexical diversity, the effect was task-specific: these dependent measures only increased during the air pressure task. Implications of the study include the need to increase teachers' awareness of possibilities to combine early science instruction and academic language learning.

A Spacelab Expert System for Remote Engineering and Science

Groleau, Nick; Colombano, Silvano; Friedland, Peter (Technical Monitor)

1994-01-01

NASA's space science program is based on strictly pre-planned activities. This approach does not always result in the best science. We describe an existing computer system that enables space science to be conducted in a more reactive manner through advanced automation techniques that have recently been used in SLS-2 October 1993 space shuttle flight. Advanced computing techniques, usually developed in the field of Artificial Intelligence, allow large portions of the scientific investigator's knowledge to be "packaged" in a portable computer to present advice to the astronaut operator. We strongly believe that this technology has wide applicability to other forms of remote science/engineering. In this brief article, we present the technology of remote science/engineering assistance as implemented for the SLS-2 space shuttle flight. We begin with a logical overview of the system (paying particular attention to the implementation details relevant to the use of the embedded knowledge for system reasoning), then describe its use and success in space, and conclude with ideas about possible earth uses of the technology in the life and medical sciences.

WFPC2 Science Capability Report

Science.gov (United States)

Brown, David I.

2001-01-01

In the following pages, a brief outline of the salient science features of Wide Field/Planetary Camera 2 (WFPC2) that impact the proposal writing process and conceptual planning of observations is presented. At the time of writing, WFPC2, while having been better defined than in the past, is far from being at the stage where science and engineering details are well enough known that concrete observational/operational sequences can be plannned with assurance. Conceptual issues are another matter. The thrust of the Science Capability Report at this time is to outline the known performance parameters and capabilities of WFPC2, filling in with specifications when necessary to hold a place for these items as they become known. Also, primary scientific and operational differences between WFPC 1 and 2 are discussed section-by-section, along with issues that remain to be determined and idiosyncrasies when known. Clearly the determination of the latter awaits some form of testing, most likely thermal/vacuum testing. All data in this report should be viewed with a jaundiced eye at this time.

The Laboratory's overall mission is sixfold. We are charged with developing nuclear warheads for defense, technology for arms control, and new concepts for defense against nuclear attack; with supporting programs for both nonnuclear defense and energy research and development; and with advancing our knowledge of science and technology so that we can respond to other national needs. Major programs in support of this mission involve nuclear weapons, energy, environmental science, and basic research. Specific areas of investigation include the design, development, and testing of nuclear weapons; nuclear safeguards and security; inertial and magnetic fusion and nuclear, solar, fossil, and geothermal energy; and basic research in physics, chemistry, mathematics, engineering, and the computer and life sciences. With the staff and facilities maintained for these and other programs, the Laboratory can respond to specific national needs in virtually all areas of the physical and life sciences. Within the Laboratory's organization, most technical research activities are carried out in three directorates: Engineering Sciences; Physics and Mathematics; and Chemistry, Earth and Life Sciences. The activities highlighted here are examples of unclassified work carried out in the seven divisions that made up the Engineering Sciences Directorate at the end of fiscal year 1983. Brief descriptions of these divisions' goals and capabilities and summaries of selected projects illustrate the diversity of talent, expertise, and facilities maintained within the Engineering Sciences Directorate

Conventional Oil and Gas Technologies. IEA ETSAP technology brief P01

Energy Technology Data Exchange (ETDEWEB)

Seljom, Pernille [IFE (Norway)], E-mail: pernille.seljom@ife.no

2010-05-15

This technology brief on conventional oil and gas technologies is part of a series produced by the IEA ETSAP agreement called the energy technology data source (E-Tech-DS). The E-Tech-DS series consists of a number of 5-10 page technology briefs similar to the IEA Energy Technology Essentials. Based on the data collected for the models that the Energy Technology Systems Analysis Programme (ETSAP) is known for, ETSAP also prepares technology briefs, called E-TechDS. The E-TechDS briefs are standardized presentations of basic information (process, status, performance, costs, potential, and barriers) for key energy technology clusters. Each brief includes an overview of the technology, charts and graphs, and a summary data table, and usually ending with some key references and further information. The E TechDS briefs are intended to offer essential, reliable and quantitative information to energy analysts, experts, policymakers, investors and media from both developed and developing countries. This specific brief focuses on the state of oil and gas exploration, development, and production/recovery technologies.

What does a science writer do all day? In a tough job market and the pressures of the publish-or-perish life, careers outside academia are enticing. But it's not just a matter of swapping research papers for news stories, or adapting course lectures to magazine articles. I am a former academic scientist (with a PhD in physics and astronomy, as well as six years of university teaching) who now works as a freelance science journalist. In this talk, I'll share my experiences, along with a brief guide to the science-writing life. Along the way, we'll touch on misconceptions ("I love teaching, so science writing should be easy!"), bad attitudes ("dumbing down" is a concept that should be nuked from orbit), and the joys of sharing science with others. There are some hard truths: don't choose science writing because you think it's an easy option compared with academic research. Nevertheless, it's a rewarding profession, and one that allows you to remember the love of science — and share that love with large numbers of other people.

Boom and bust in popular science

Directory of Open Access Journals (Sweden)

Jon Turney

2007-03-01

Full Text Available The obvious thing to say about popular science publishing in the last twenty years is that there has been a lot of it! That is important in itself. But it also means it is hazardous to offer general comment. The British journalist and commentator Bryan Appleyard recently wrote in the Sunday Times that the “hard stuff” in science was no longer attracting so many readers. Books answering many small questions about the world, or evoking a sense of wonder, do better - he reckons - than those which offer large certainties based on a scientific, or scientistic view of the world. That type, Appleyard claims, dominated the field for years after Steven Hawking’s A Brief History of Time, with its promise of a theory of everything.

The Committee on Atomic, Molecular and Optical Sciences (CAMOS) of the National Research Council (NRC) is charged with monitoring the health of the field of atomic, molecular, and optical (AMO) science in the United States. Accordingly, the Committee identifies and examines both broad and specific issues affecting the field. Regular meetings, teleconferences, briefings from agencies and the scientific community, the formation of study panels to prepare reports, and special symposia are among the mechanisms used by the CAMOS to meet its charge. This progress report presents a review of CAMOS activities from February 1, 1993 to January 31, 1994. The details of prior activities are discussed in earlier progress reports. This report also includes the status of activities associated with the CAMOS study on the field that is being conducted by the Panel on the Future of Atomic, Molecular, and Optical Sciences (FAMOS). During the above period, CAMOS has continued to track and participate in, when requested, discussions on the health of the field. Much of the perspective of CAMOS has been presented in the recently-published report Research Briefing on Selected Opportunities in Atomic, Molecular, and Optical Sciences. That report has served as the basis for briefings to representatives of the federal government as well as the community-at-large. In keeping with its charge to monitor the health of the field, CAMOS launched a study designed to highlight future directions of the field

Eisenstein, Robert A.

2013-04-01

The Santa Fe Alliance for Science (SFAFS) was founded in May, 2005. SFAFS exists to provide assistance in K-14 math and science education in the greater Santa Fe area. It does this via extensive programs (1) in math and science tutoring at Santa Fe High School, Santa Fe Community College and to a lesser degree at other schools, (2) science fair advising and judging, (3) its ``Santa Fe Science Cafe for Young Thinkers'' series, (4) a program of professional enrichment for K-12 math and science teachers, and (5) a fledging math intervention program in middle school math. Well over 150 STEM professionals, working mostly as volunteers, have contributed since our beginning. Participation by students, parents and teachers has increased dramatically over the years, leading to much more positive views of math and science, especially among elementary school students and teachers. Support from the community and from local school districts has been very strong. I will present a brief status report on SFAFS activities, discuss some of the lessons learned along the way and describe briefly some ideas for the future. More information can be found at the SFAFS website, www.sfafs.org.

The National Cancer Institute's Physical Sciences - Oncology Network

Science.gov (United States)

Espey, Michael Graham

In 2009, the NCI launched the Physical Sciences - Oncology Centers (PS-OC) initiative with 12 Centers (U54) funded through 2014. The current phase of the Program includes U54 funded Centers with the added feature of soliciting new Physical Science - Oncology Projects (PS-OP) U01 grant applications through 2017; see NCI PAR-15-021. The PS-OPs, individually and along with other PS-OPs and the Physical Sciences-Oncology Centers (PS-OCs), comprise the Physical Sciences-Oncology Network (PS-ON). The foundation of the Physical Sciences-Oncology initiative is a high-risk, high-reward program that promotes a `physical sciences perspective' of cancer and fosters the convergence of physical science and cancer research by forming transdisciplinary teams of physical scientists (e.g., physicists, mathematicians, chemists, engineers, computer scientists) and cancer researchers (e.g., cancer biologists, oncologists, pathologists) who work closely together to advance our understanding of cancer. The collaborative PS-ON structure catalyzes transformative science through increased exchange of people, ideas, and approaches. PS-ON resources are leveraged to fund Trans-Network pilot projects to enable synergy and cross-testing of experimental and/or theoretical concepts. This session will include a brief PS-ON overview followed by a strategic discussion with the APS community to exchange perspectives on the progression of trans-disciplinary physical sciences in cancer research.

GCM simulations of stable isotopes in the water cycle in comparison with GNIP observations over East Asia

Science.gov (United States)

Zhang, Xinping; Sun, Zhian; Guan, Huade; Zhang, Xinzhu; Wu, Huawu; Huang, Yimin

2012-08-01

In this paper, we examine the performance of four isotope incorporated GCMs, i.e., ECHAM4 (University of Hamburg), HadCM3 (Hadley Centre), GISS E (Goddard Institute of Space Sciences), and MUGCM (Melbourne University), by comparing the model results with GNIP (Global Network of Isotopes in Precipitation) observations. The spatial distributions of mean annual δD and mean annual deuterium excess d in precipitation, and the relationship between δ 18O and δD in precipitation, are compared between GCMs and GNIP data over East Asia. Overall, the four GCMs reproduce major characteristics of δD in precipitation as observed by GNIP. Among the four models, the results of ECHAM4 and GISS E are more consistent with GNIP observed precipitation δD distribution. The simulated d distributions are less consistent with the GNIP results. This may indicate that kinetic fractionation processes are not appropriately represented in the isotopic schemes of GCMs. The GCM modeled MWL (meteoric water line) slopes are close to the GNIP derived MWL, but the simulated MWL intercepts are significantly overestimated. This supports that the four isotope incorporated GCMs may not represent the kinetic fractionation processes well. In term of LMWLs (local meteoric water lines), the simulated LMWL slopes are similar to those from GNIP observations, but slightly overestimated for most locations. Overall, ECHAM4 has better capability in simulating MWL and LMWLs, followed by GISS E. Some isotopic functions (especially those related to kinetic fractionation) and their parameterizations in GCMs may have caused the discrepancy between the simulated and GNIP observed results. Future work is recommended to improve isotopic function parameterization on the basis of the high-resolution isotope observations.

Mean Field Games Models-A Brief Survey

KAUST Repository

Gomes, Diogo A.

2013-11-20

The mean-field framework was developed to study systems with an infinite number of rational agents in competition, which arise naturally in many applications. The systematic study of these problems was started, in the mathematical community by Lasry and Lions, and independently around the same time in the engineering community by P. Caines, Minyi Huang, and Roland Malhamé. Since these seminal contributions, the research in mean-field games has grown exponentially, and in this paper we present a brief survey of mean-field models as well as recent results and techniques. In the first part of this paper, we study reduced mean-field games, that is, mean-field games, which are written as a system of a Hamilton-Jacobi equation and a transport or Fokker-Planck equation. We start by the derivation of the models and by describing some of the existence results available in the literature. Then we discuss the uniqueness of a solution and propose a definition of relaxed solution for mean-field games that allows to establish uniqueness under minimal regularity hypothesis. A special class of mean-field games that we discuss in some detail is equivalent to the Euler-Lagrange equation of suitable functionals. We present in detail various additional examples, including extensions to population dynamics models. This section ends with a brief overview of the random variables point of view as well as some applications to extended mean-field games models. These extended models arise in problems where the costs incurred by the agents depend not only on the distribution of the other agents, but also on their actions. The second part of the paper concerns mean-field games in master form. These mean-field games can be modeled as a partial differential equation in an infinite dimensional space. We discuss both deterministic models as well as problems where the agents are correlated. We end the paper with a mean-field model for price impact. © 2013 Springer Science+Business Media New York.

The Ocean Carbon States Database: a proof-of-concept application of cluster analysis in the ocean carbon cycle

Science.gov (United States)

Latto, Rebecca; Romanou, Anastasia

2018-03-01

In this paper, we present a database of the basic regimes of the carbon cycle in the ocean, the ocean carbon states, as obtained using a data mining/pattern recognition technique in observation-based as well as model data. The goal of this study is to establish a new data analysis methodology, test it and assess its utility in providing more insights into the regional and temporal variability of the marine carbon cycle. This is important as advanced data mining techniques are becoming widely used in climate and Earth sciences and in particular in studies of the global carbon cycle, where the interaction of physical and biogeochemical drivers confounds our ability to accurately describe, understand, and predict CO2 concentrations and their changes in the major planetary carbon reservoirs. In this proof-of-concept study, we focus on using well-understood data that are based on observations, as well as model results from the NASA Goddard Institute for Space Studies (GISS) climate model. Our analysis shows that ocean carbon states are associated with the subtropical-subpolar gyre during the colder months of the year and the tropics during the warmer season in the North Atlantic basin. Conversely, in the Southern Ocean, the ocean carbon states can be associated with the subtropical and Antarctic convergence zones in the warmer season and the coastal Antarctic divergence zone in the colder season. With respect to model evaluation, we find that the GISS model reproduces the cold and warm season regimes more skillfully in the North Atlantic than in the Southern Ocean and matches the observed seasonality better than the spatial distribution of the regimes. Finally, the ocean carbon states provide useful information in the model error attribution. Model air-sea CO2 flux biases in the North Atlantic stem from wind speed and salinity biases in the subpolar region and nutrient and wind speed biases in the subtropics and tropics. Nutrient biases are shown to be most important in

2013-06-01

To evaluate the feasibility of an iPad-based documented patient briefing for Magnetic Resonance Imaging (MRI) examinations. A standard briefing sheet and questionnaire for a MRI scan was converted from paper form into an iPad application. Twenty patients, who had been referred for an MRI scan, were briefed about the examination in paper form as well as via the iPad application before performing the MRI scan. Time each patient needed for the briefing and the number of questions that came up were documented. Patients' acceptance of the electronic briefing was assessed using a questionnaire. The mean processing time was 2.36 min (range 0.58 to 09.35 min., standard deviation ±2.05 min) for the paper-based briefing and 4.15 min (range 1.56 to 13.48 min, SD ± 2.36 min) for the app-based briefing. Concerning technical aspects, patients asked two questions during the app-based briefing; no questions arose during the paper-based briefing. Six patients preferred electronic briefing and four patients, the paper-based form. No patient preferred the electronic form with additional multimedial information. Eight participants did not mind which briefing version was used; two participants did not express their preference at all. Our experiences showed that electronic briefing using an iPad is feasible and has the potential to become a user-friendly alternative to the conventional paper-based approach. Owing to the broad range of the results, a follow-up study will seek to determine the influencing factors on processing time and other potential questions.

Manning, Wendy D; Fettro, Marshal Neal; Lamidi, Esther

2014-08-01

Recent legal cases before the Supreme Court of the United States were challenging federal definitions of marriage created by the Defense of Marriage Act and California's voter approved Proposition 8 which limited marriage to different-sex couples only. Social science literature regarding child well-being was being used within these cases, and the American Sociological Association sought to provide a concise evaluation of the literature through an amicus curiae brief. The authors were tasked in the assistance of this legal brief by reviewing literature regarding the well-being of children raised within same-sex parent families. This article includes our assessment of the literature, focusing on those studies, reviews and books published within the past decade. We conclude that there is a clear consensus in the social science literature indicating that American children living within same-sex parent households fare just, as well as those children residing within different-sex parent households over a wide array of well-being measures: academic performance, cognitive development, social development, psychological health, early sexual activity, and substance abuse. Our assessment of the literature is based on credible and methodologically sound studies that compare well-being outcomes of children residing within same-sex and different-sex parent families. Differences that exist in child well-being are largely due to socioeconomic circumstances and family stability. We discuss challenges and opportunities for new research on the well-being of children in same-sex parent families.

The Intersections of Science and Practice: Examples From FitnessGram® Programming.

Science.gov (United States)

Welk, Gregory J

2017-12-01

The FitnessGram® program has provided teachers with practical tools to enhance physical education programming. A key to the success of the program has been the systematic application of science to practice. Strong research methods have been used to develop assessments and standards for use in physical education, but consideration has also been given to ensure that programming meets the needs of teachers, students, parents, and other stakeholders. This essay summarizes some of these complex and nuanced intersections between science and practice with the FitnessGram® program. The commentaries are organized into 5 brief themes: science informing practice; practice informing science; balancing science and practice; promoting evidence-based practice; and the integration of science and practice. The article draws on personal experiences with the FitnessGram® program and is prepared based on comments shared during the 37th Annual C. H. McCloy Research Lecture at the 2017 SHAPE America - Society of Health and Physical Educators Convention.

The influence of client brief and change order in construction project

Science.gov (United States)

Mahat, N. A. A.; Adnan, H.

2018-02-01

Construction briefing is a statement of needs about intentions and projects objectives. Briefing process is the preliminary stage in the design process and successful briefing can achieve project delivery right on target time, cost and quality of project confidently. Although there are many efforts to approach client’s requirement and needs for a project, it is still not collected adequately to make proper solutions in design. Thus, these may lead the client to include change orders during the construction phase. This paper is concerned toward the influence of client’s briefing of a construction project that impact on the change order on the construction works. The research objective is to identify the influence of client’s brief on change orders, therefore, the aims of the research is to reduce change orders in project delivery. This research adopted both qualitative and quantitative data collection methods which are content analysis and semi structure interview. The findings highlight factors contributing to change orders and the essential attributes of clients during the briefing stage that may help minimise them.

Rockets: Physical science teacher's guide with activities

Vogt, Gregory L.; Rosenberg, Carla R. (Editor)

1993-01-01

This guide begins with background information sections on the history of rocketry, scientific principles, and practical rocketry. The sections on scientific principles and practical rocketry are based on Isaac Newton's three laws of motion. These laws explain why rockets work and how to make them more efficient. The background sections are followed with a series of physical science activities that demonstrate the basic science of rocketry. Each activity is designed to be simple and take advantage of inexpensive materials. Construction diagrams, materials and tools lists, and instructions are included. A brief discussion elaborates on the concepts covered in the activities and is followed with teaching notes and discussion questions. The guide concludes with a glossary of terms, suggested reading list, NASA educational resources, and an evaluation questionnaire with a mailer.

Using In Situ Observations and Satellite Retrievals to Constrain Large-Eddy Simulations and Single-Column Simulations: Implications for Boundary-Layer Cloud Parameterization in the NASA GISS GCM

Science.gov (United States)

Remillard, J.

2015-12-01

Two low-cloud periods from the CAP-MBL deployment of the ARM Mobile Facility at the Azores are selected through a cluster analysis of ISCCP cloud property matrices, so as to represent two low-cloud weather states that the GISS GCM severely underpredicts not only in that region but also globally. The two cases represent (1) shallow cumulus clouds occurring in a cold-air outbreak behind a cold front, and (2) stratocumulus clouds occurring when the region was dominated by a high-pressure system. Observations and MERRA reanalysis are used to derive specifications used for large-eddy simulations (LES) and single-column model (SCM) simulations. The LES captures the major differences in horizontal structure between the two low-cloud fields, but there are unconstrained uncertainties in cloud microphysics and challenges in reproducing W-band Doppler radar moments. The SCM run on the vertical grid used for CMIP-5 runs of the GCM does a poor job of representing the shallow cumulus case and is unable to maintain an overcast deck in the stratocumulus case, providing some clues regarding problems with low-cloud representation in the GCM. SCM sensitivity tests with a finer vertical grid in the boundary layer show substantial improvement in the representation of cloud amount for both cases. GCM simulations with CMIP-5 versus finer vertical gridding in the boundary layer are compared with observations. The adoption of a two-moment cloud microphysics scheme in the GCM is also tested in this framework. The methodology followed in this study, with the process-based examination of different time and space scales in both models and observations, represents a prototype for GCM cloud parameterization improvements.

To specify the principles, definition and dimensions of the new nutrition science. To identify nutrition, with its application in food and nutrition policy, as a science with great width and breadth of vision and scope, in order that it can fully contribute to the preservation, maintenance, development and sustenance of life on Earth. A brief overview shows that current conventional nutrition is defined as a biological science, although its governing and guiding principles are implicit only, and no generally agreed definition is evident. Following are agreements on the principles, definition and dimensions of the new nutrition science, made by the authors as participants at a workshop on this theme held on 5-8 April 2005 at the Schloss Rauischholzhausen, Justus-Liebig University, Giessen, Germany. Nutrition science as here specified will retain its current 'classical' identity as a biological science, within a broader and integrated conceptual framework, and will also be confirmed as a social and environmental science. As such it will be concerned with personal and population health, and with planetary health--the welfare and future of the whole physical and living world of which humans are a part.

Leong, Katharina Brigitte Margarethe Siew Lan; Hanskamp-Sebregts, Mirelle; van der Wal, Raymond A; Wolff, Andre P

2017-12-14

This study was carried out to improve patient safety in the operating theatre by the introduction of perioperative briefing and debriefing, which focused on an optimal collaboration between surgical team members. A prospective intervention study with one pretest and two post-test measurements: 1 month before and 4 months and 2.5 years after the implementation of perioperative briefing and debriefing, respectively. Operating theatres of a tertiary care hospital with 875 beds in the Netherlands. All members of five surgical teams participated in the perioperative briefing and debriefing. The implementation of perioperative briefing and debriefing from July 2012 to January 2014. The primary outcome was changes in the team climate, measured by the Team Climate Inventory. Secondary outcomes were the experiences of surgical teams with perioperative briefing and debriefing, measured with a structured questionnaire, and the duration of the briefings, measured by an independent observer. Two and a half years after the introduction of perioperative briefing and debriefing, the team climate increased statistically significant (p≤0.05). Members of the five surgical teams strongly agreed with the positive influence of perioperative briefing and debriefing on clear agreements and reminding one another of the agreements of the day. They perceived a higher efficiency of the surgical programme with more operations starting on time and less unexpectedly long operation time. The perioperative briefing took less than 4 min to conduct. Perioperative briefing and debriefing improved the team climate of surgical teams and the efficiency of their work within the operating theatre with acceptable duration per briefing. Surgical teams with alternating team compositions have the most benefit of briefing and debriefing. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Committee on Atomic, Molecular, and Optical Sciences (CAMOS)

International Nuclear Information System (INIS)

1992-01-01

The Committee on Atomic, Molecular, and Optical Sciences is a standing committee under the auspices of the Board on Physics and Astronomy, Commission on Physical Sciences, Mathematics, and Applications of the National Academy of Sciences -- National Research Council. The atomic, molecular, and optical (AMO) sciences represent a broad and diverse field in which much of the research is carried out by small groups. These groups generally have not operated in concert with each other and, prior to the establishment of CAMOS, there was no single committee or organization that accepted the responsibility of monitoring the continuing development and assessing the general public health of the field as a whole. CAMOS has accepted this responsibility and currently provides a focus for the AMO community that is unique and essential. The membership of CAMOS is drawn from research laboratories in universities, industry, and government. Areas of expertise on the committee include atomic physics, molecular science, and optics. A special effort has been made to include a balanced representation from the three subfields. (A roster is attached.) CAMOS has conducted a number of studies related to the health of atomic and molecular science and is well prepared to response to requests for studies on specific issues. This report brief reviews the committee work of progress

The early history of ideas on brief interventions for alcohol.

Science.gov (United States)

McCambridge, Jim; Cunningham, John A

2014-04-01

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

Briefing Products - Tools for Communicating Technical Issues to a Non-Technical Audience

International Nuclear Information System (INIS)

Clark, Harvey; Foster, Kevin T.

2011-01-01

Briefing Products are a new NARAC/IMAAC product line designed to communicate the consequences of a radiological, nuclear, chemical or biological agent incident to non-technical decision makers and key leaders. Each Briefing Product addresses a single decision or issue focused on potential actions that should be considered when responding to a hazard, while avoiding the use of technical or regulatory jargon. Briefing Products do not make protective action recommendations, although they do concretely assist decision-makers with development of their own protective actions by quoting or paraphrasing the published guidance relevant to the decision at hand. Briefing Products are produced in sets tailored to specific types of incident which together depict the key decisions and characteristics of the incident. Each Briefing Product in the set consists of three elements: (1) Primary Effects, (2) Key Points and (3) Presenter Notes. Both the Primary Effects and Key Points are ready for direct presentation, while the Presenter Notes are designed to provide background information to the presenter and are not for direct presentation to the audience. The Briefing Products themselves are alternative presentations of results from the customary standard NARAC/IMAAC technical products. Currently, Briefing Products are available for detonation of both RDDs (Radiological Dispersal Devices) and INDs (Improvised Nuclear Devices). A new set of products tailored to nuclear power plant (NPP) accidents is currently under development. This paper describes the scope, structure and content of the Briefing Product sets. Examples from the two sets of Briefing Products now available are presented.

Boright, John

2017-01-01

Science academies were originally created to facilitate science communication and later to recognize excellence. But in the last 20 years some 150 academies of science, engineering,and medicine around the world have united to cooperate in contributing to human welfare, by: 1. Providing evidence-based inputs to national, regional, and global policies addressing human needs, and 2. Conducting cooperative programs to increase the capacity of academies to provide such advice, and to better connect academies to publics and to policy makers. Examples: At the global level, 112 academies of science produce brief common statements on major global issues. They have also created an organization to provide in-depth reports on major issues such as a transition to sustainable energy systems, boosting agricultural productivity in Africa, and a guide to responsible conduct in the global research enterprise. Regional networks of those academies, in Africa, the Americas, Asia, and Europe conduct program on topics such as water, energy, engagement of women in science, and science education. They also help and mentor new academies.

Integration and Implementation Sciences: Building a New Specialization

Directory of Open Access Journals (Sweden)

Gabriele Bammer

2005-12-01

Full Text Available Developing a new specialization - Integration and Implementation Sciences - may be an effective way to draw together and significantly strengthen the theory and methods necessary to tackle complex societal issues and problems. This paper presents an argument for such a specialization, beginning with a brief review of calls for new research approaches that combine disciplines and interact more closely with policy and practice. It posits that the core elements of Integration and Implementation Sciences already exist, but that the field is currently characterized by fragmentation and marginalization. The paper then outlines three sets of characteristics that will delineate Integration and Implementation Sciences. First is that the specialization will aim to find better ways to deal with the defining elements of many current societal issues and problems: namely complexity, uncertainty, change, and imperfection. Second is that there will be three theoretical and methodological pillars for doing this: 1 systems thinking and complexity science, 2 participatory methods, and 3 knowledge management, exchange, and implementation. Third, operationally, Integration and Implementation Sciences will be grounded in practical application, and generally involve large-scale collaboration. The paper concludes by examining where Integration and Implementation Sciences would sit in universities, and outlines a program for further development of the field. An appendix provides examples of Integration and Implementation Sciences in action.

In 1957, Sandia National Laboratories (Sandia) initiated its first programs in fundamental science, in support of its primary nuclear weapons mission. In 1974, Sandia initiated programs in fundamental science supported by the Department of Energy's Office of Science (DOE-SC). These latter programs have grown to the point where, today in 2011, support of Sandia's programs in fundamental science is dominated by that Office. In comparison with Sandia's programs in technology and mission applications, however, Sandia's programs in fundamental science are small. Hence, Sandia's fundamental science has been strongly influenced by close interactions with technology and mission applications. In many instances, these interactions have been of great mutual benefit, with synergies akin to a positive 'Casimir's spiral' of progress. In this report, we review the history of Sandia's fundamental science programs supported by the Office of Science. We present: (a) a technical and budgetary snapshot of Sandia's current programs supported by the various suboffices within DOE-SC; (b) statistics of highly-cited articles supported by DOE-SC; (c) four case studies (ion-solid interactions, combustion science, compound semiconductors, advanced computing) with an emphasis on mutually beneficial interactions between science, technology, and mission; and (d) appendices with key memos and reminiscences related to fundamental science at Sandia.

Proceedings of the one hundred and first Indian Science Congress: brief notes on the lectures and presentations

International Nuclear Information System (INIS)

2014-01-01

Indian capabilities in science and technology cover an impressive range of diverse disciplines, areas of competence and of applications. India's strength in basic research is recognized internationally. Successes in agriculture, health care, chemicals and pharmaceuticals, nuclear energy, astronomy and astrophysics, space technology and applications, defense research, biotechnology, electronics, information technology and oceanography are widely acknowledged. Major national achievements include very significant increase in food production, eradication or control of several diseases and increased life expectancy of our citizens. Research and development (R and D) is an inseparable part of science and technology, with India fast emerging as the global R and D hub. While these developments have been highly satisfying, one is also aware of the dramatic changes that have taken place, and continue to do so, in the practice of science, in technology development, and their relationships with, and impact on, society. Mainly remarkable is the rapidity with which science and technology is moving ahead. Science is becoming increasingly inter- and multi-disciplinary, and calls for multi-institutional and, in several cases, multi-country participation. Major experimental facilities, even in several areas of basic research, require very large material, human and intellectual resources. Science and technology have become so closely intertwined, and so reinforce each other that, to be effective, any policy needs to view them together. The continuing revolutions in the field of information and communication technology have had profound impact on the manner and speed with which scientific information becomes available, and scientific interactions take place.

Building on Watzlawick's observations of certain similarities between judo and brief strategic therapy, this paper develops theoretic and pragmatic parallels between brief strategic therapy and a sophisticated martial art system, Aikido. After presenting the contextual similarities of the two conceptual systems as parallel "challenges" to the therapist and Aikidoist to effect change, the similarities in basic principles of practice are presented. The similarities in the philosophical and attitudinal positions of these conceptual systems are then delineated, followed by a case example that integrates the various concepts in the paper.

Impact of improved Greenland ice sheet surface representation in the NASA GISS ModelE2 GCM on simulated surface mass balance and regional climate

Science.gov (United States)

Alexander, P. M.; LeGrande, A. N.; Fischer, E.; Tedesco, M.; Kelley, M.; Schmidt, G. A.; Fettweis, X.

2017-12-01

Towards achieving coupled simulations between the NASA Goddard Institute for Space Studies (GISS) ModelE2 general circulation model (GCM) and ice sheet models (ISMs), improvements have been made to the representation of the ice sheet surface in ModelE2. These include a sub-grid-scale elevation class scheme, a multi-layer snow model, a time-variable surface albedo scheme, and adjustments to parameterization of sublimation/evaporation. These changes improve the spatial resolution and physical representation of the ice sheet surface such that the surface is represented at a level of detail closer to that of Regional Climate Models (RCMs). We assess the impact of these changes on simulated Greenland Ice Sheet (GrIS) surface mass balance (SMB). We also compare ModelE2 simulations in which winds have been nudged to match the European Center for Medium-Range Weather Forecasts (ECMWF) ERA-Interim reanalysis with simulations from the Modèle Atmosphérique Régionale (MAR) RCM forced by the same reanalysis. Adding surface elevation classes results in a much higher spatial resolution representation of the surface necessary for coupling with ISMs, but has a negligible impact on overall SMB. Implementing a variable surface albedo scheme increases melt by 100%, bringing it closer to melt simulated by MAR. Adjustments made to the representation of topography-influenced surface roughness length in ModelE2 reduce a positive bias in evaporation relative to MAR. We also examine the impact of changes to the GrIS surface on regional atmospheric and oceanic climate in coupled ocean-atmosphere simulations with ModelE2, finding a general warming of the Arctic due to a warmer GrIS, and a cooler North Atlantic in scenarios with doubled atmospheric CO2 relative to pre-industrial levels. The substantial influence of changes to the GrIS surface on the oceans and atmosphere highlight the importance of including these processes in the GCM, in view of potential feedbacks between the ice sheet

Atomic layer deposition (ALD) is a technique increasingly used in nanotechnology and ultrathin film deposition; it is ideal for films in the nanometer and Angstrom length scales. ALD can effectively be used to modify the surface chemistry and functionalization of engineering-related and biologically important surfaces. It can also be used to alter the mechanical, electrical, chemical, and other properties of materials that are increasingly used in biomedical engineering and biological sciences. ALD is a relatively new technique for optimizing materials for use in bio-nanotechnology. Here, after a brief review of the more widely used modes of ALD and a few of its applications in biotechnology, selected results that show the potential of ALD in bio-nanotechnology are presented. ALD seems to be a promising means for tuning the hydrophilicity/hydrophobicity characteristics of biomedical surfaces, forming conformal ultrathin coatings with desirable properties on biomedical substrates with a high aspect ratio, tuning the antibacterial properties of substrate surfaces of interest, and yielding multifunctional biomaterials for medical implants and other devices.

Three brief assessments of math achievement.

Science.gov (United States)

Steiner, Eric T; Ashcraft, Mark H

2012-12-01

Because of wide disparities in college students' math knowledge-that is, their math achievement-studies of cognitive processing in math tasks also need to assess their individual level of math achievement. For many research settings, however, using existing math achievement tests is either too costly or too time consuming. To solve this dilemma, we present three brief tests of math achievement here, two drawn from the Wide Range Achievement Test and one composed of noncopyrighted items. All three correlated substantially with the full achievement test and with math anxiety, our original focus, and all show acceptable to excellent reliability. When lengthy testing is not feasible, one of these brief tests can be substituted.

Print pharmaceutical advertisements in the United States require inclusion of a brief summary of side effects, warnings, precautions, and contraindications from the labeling. The full package insert, which sponsors have traditionally used to fulfill the brief summary requirement, does not adhere to health literacy best practices, limiting its value to consumers. This study compared the understandability and usability of brief summaries in 3 formats designed to be more consumer friendly. Three brief summary formats were tested: (1) 2-column "Question and Answer"; (2) "Prescription Drug Facts Box," similar to current US over-the-counter drug facts labeling; and (3) "Health Literacy," based on clear communication principles. Researchers evaluated the formats using the Suitability Assessment of Materials (SAM) tool and conducted structured, scripted, one-on-one interviews (usability tests) with participants with estimated low to average education levels. This research was replicated across 2 therapeutic areas (type 2 diabetes and plaque psoriasis). SAM scores showed that the Health Literacy format outperformed the Question and Answer format and the Prescription Drug Facts Box format in both therapeutic areas, with both Health Literacy brief summaries rated on the SAM as "superior." Qualitative usability tests supported the SAM findings, with the Health Literacy format preferred consistently over the Question and Answer format, and more often than not over the Prescription Drug Facts Box format. Sponsors can employ a user-tested Health Literacy format to improve the understandability and usability of brief summaries with patients.

The present study offers a cross-cultural examination of the effect of prayer on forgiveness. American (n = 51) and Indian (n = 100) participants either prayed for their romantic partner (prayer condition) or described their romantic partner's physical attributes (control condition). Prayers were self-guided and lasted 3 minutes. Pre-test and post-test measures of retaliation were completed. Results showed that participants in the prayer group showed statistically significant decreases in retaliation motives from pre-test to post-test and the magnitude of this change was not different across cultures. Control groups in both cultures showed no change. Because of the religious diversity present in the Indian sample, the robustness of the effect of prayer on forgiveness was tested across Christian, Hindu and Muslim Indians. Religious affiliation did not moderate the effect of prayer on forgiveness in this sample. Results suggest that a brief prayer is capable of producing real change in forgiveness and this change is consistent across American and Indian cultures and across three different religious groups in India. Brief prayer for others that enhances forgiveness may be useful for individuals in close relationships, in certain counselling settings and for people in many different walks of life. © 2015 International Union of Psychological Science.

Communicating the Science from NASA's Astrophysics Missions

Communicating science from NASA's Astrophysics missions has multiple objectives, which leads to a multi-faceted approach. While a timely dissemination of knowledge to the scientific community follows the time-honored process of publication in peer reviewed journals, NASA delivers newsworthy research result to the public through news releases, its websites and social media. Knowledge in greater depth is infused into the educational system by the creation of educational material and teacher workshops that engage students and educators in cutting-edge NASA Astrophysics discoveries. Yet another avenue for the general public to learn about the science and technology through NASA missions is through exhibits at museums, science centers, libraries and other public venues. Examples of the variety of ways NASA conveys the excitement of its scientific discoveries to students, educators and the general public will be discussed in this talk. A brief overview of NASA's participation in the International Year of Light will also be given, as well as of the celebration of the twenty-fifth year of the launch of the Hubble Space Telescope.

Investigating Changes in Student Attitudes and Understanding of Science through Participation in Citizen Science Projects in College Coursework

Cardamone, Carolin; Cobb, Bethany E.

2018-01-01

Over the last decade, web-based “citizen science” projects such as the Zooniverse have allowed volunteers and professional scientists to work together for the advancement of science. While much attention has been paid to the benefits to science from these new projects, less attention has been paid to their impact on the participants and, in particular, to the projects’ potential to impact students who might engage in these projects through coursework. We report on a study engaging students in introductory astronomy classes at the George Washington University and Wheelock College in an assignment in which each student individually contributed to a “physics” or “space” citizen science project of their choice, and groups of students worked together to understand and articulate the scientific purpose of a citizen science project to which they all contributed. Over the course of approximately four weeks, the students kept logs of their individual contributions to the project, and recorded a brief reflection on each of their visits (noting, for example, interesting or confusing things they might encounter along the way). The project culminated with each group delivering a creative presentation that demonstrated their understanding of both the science goals of the project and the value of their own contributions to the project. In this talk, we report on the experience of the students with the project and on an assessment of the students’ attitudes toward science and knowledge of the process of science completed before the introduction of the assignment and again at its conclusion.

In patients with severe mental disorders outcome measurement should include symptoms, cognition, functioning and quality of life at least. Shorter and efficient instruments have greater potential for pragmatic and valid clinical utility. Our aim was to develop the Spanish UPSA Brief scale (Sp-UPSA-Brief). Naturalistic, 6-month follow-up, multicentre study. 139 patients with schizophrenia, 57 with bipolar disorder and 31 controls were evaluated using the Sp-UPSA, CGI-S, GAF, and PSP. We conducted a multivariate linear regression model to identify candidate subscales for the Sp-UPSA-Brief. The stepwise regression model for patients with schizophrenia showed that communication and transportation Sp-UPSA subscales entered first and second at pbipolar disorder transportation and communication Sp-UPSA subscales entered first and second at pbipolar patients. Test-retest was 0.66 and 0.64 (pbipolar patients (p<0.0001).The Sp-UPSA-Brief discriminated between patients and controls. In schizophrenia patients it also discriminated among different levels of illness severity according to CGI-S scores. The Sp-UPSA-Brief is an alternate instrument to evaluate functional capacity that is valid and reliable. Having a shorter instrument makes it more feasible to assess functional capacity in patients with severe mental disorders, especially in everyday clinical practice. Copyright © 2013 SEP y SEPB.

The Machinery Of Climate Anti-Science, Its Efforts Against Education, Top To Bottom

Science.gov (United States)

Mashey, J. R.

2014-12-01

"There's always one every year" a fine local science teacher said after once again being hassled by a vocal parent for teaching appropriate climate science in school. How does that happen? The machinery of climate anti-science starts from the top with funders working through a maze of money paths, think tanks and front groups, employing spokespeople who can be portrayed as experts. While much of the money flows are still dark, some have been exposed over the last few years, and the effects finally filter down to the state and local levels of education. Among others, the Heartland Institute has a long history of trying to inject anti-science into K-12 and college education, having sent books, DVDs or brochures to teachers or school boards, as well as monthly newsletters to state legislators. Such are aimed at the top of the state or local organizations that affect education. For a vocal subset of the citizenry, a constant flow of misinformation from books, blogs, newsletters and some newspapers and magazines stirs action such as writing letters to editors, complaining to schools, calling on pseudo-experts and demanding equal time for pseudoscience. As the teacher said, it only takes one person to cause trouble at the local level. After a brief review of the overall machinery, this focuses on examples of anti-education tactics seen already, with some brief advice for climate scientists and educators who need to understand the machinery that supports such tactics. Some earlier history is included in http://www.desmogblog.com/2012/10/23/fakery-2-more-funny-finances-free-tax, but other attempts have surfaced in last few years, including state-wide efforts to reject Common Core Educational standard to avoid teaching climate science. Fortunately, school boards sometimes respond quite well, including one just recently in Pennsylvania.

The gap in educational attainment separating underrepresented minorities from Whites and Asians remains wide. Such a gap has significant impact on workforce diversity and inclusion among cross-cutting Biomedical Data Science (BDS) research, which presents great opportunities as well as major challenges for addressing health disparities. This article provides a brief description of the newly established National Institutes of Health Big Data to Knowledge (BD2K) diversity initiatives at four universities: California State University, Monterey Bay; Fisk University; University of Puerto Rico, Río Piedras Campus; and California State University, Fullerton. We emphasize three main barriers to BDS careers (ie, preparation, exposure, and access to resources) experienced among those pioneer programs and recommendations for possible solutions (ie, early and proactive mentoring, enriched research experience, and data science curriculum development). The diversity disparities in BDS demonstrate the need for educators, researchers, and funding agencies to support evidence-based practices that will lead to the diversification of the BDS workforce.

Screening and brief intervention for unhealthy drug use: little or no efficacy

Directory of Open Access Journals (Sweden)

Richard eSaitz

2014-09-01

Full Text Available Unhealthy drug use ranges from use that risks health harms through severe drug use disorders. This narrative review addresses whether screening and brief intervention, efficacious for risky alcohol use, has efficacy for reducing other drug use and consequences. Brief intervention among those seeking help shows some promise. Screening tools have been validated though most are neither brief nor simple enough for use in general health settings. Several randomized trials have tested the efficacy of brief intervention for unhealthy drug use identified by screening in general health settings (i.e. in people not seeking help for their drug use. Substantial evidence now suggests efficacy is limited or non-existent. Reasons likely include a range of actual and perceived severity (or lack of severity, concomitant unhealthy alcohol use and comorbid mental health conditions, and the wide range of types of unhealthy drug use (e.g. from marijuana, to prescription drugs, to heroin. Although brief intervention may have some efficacy for unhealthy drug users seeking help, the model of screening and brief intervention that has effects in primary care settings on risky alcohol use may not be efficacious for other drug use.

Clinical outcomes and cost-effectiveness of brief guided parent-delivered cognitive behavioural therapy and solution-focused brief therapy for treatment of childhood anxiety disorders: a randomised controlled trial.

Half of all lifetime anxiety disorders emerge before age 12 years; however, access to evidence-based psychological therapies for affected children is poor. We aimed to compare the clinical outcomes and cost-effectiveness of two brief psychological treatments for children with anxiety referred to routine child mental health settings. We hypothesised that brief guided parent-delivered cognitive behavioural therapy (CBT) would be associated with better clinical outcomes than solution-focused brief therapy and would be cost-effective. We did this randomised controlled trial at four National Health Service primary child and mental health services in Oxfordshire, UK. Children aged 5-12 years referred for anxiety difficulties were randomly allocated (1:1), via a secure online minimisation tool, to receive brief guided parent-delivered CBT or solution-focused brief therapy, with minimisation for age, sex, anxiety severity, and level of parental anxiety. The allocation sequence was not accessible to the researcher enrolling participants or to study assessors. Research staff who obtained outcome measurements were masked to group allocation and clinical staff who delivered the intervention did not measure outcomes. The primary outcome was recovery, on the basis of Clinical Global Impressions of Improvement (CGI-I). Parents recorded patient-level resource use. Quality-adjusted life-years (QALYs) for use in cost-utility analysis were derived from the Child Health Utility 9D. Assessments were done at baseline (before randomisation), after treatment (primary endpoint), and 6 months after treatment completion. We did analysis by intention to treat. This trial is registered with the ISCRTN registry, number ISRCTN07627865. Between March 23, 2012, and March 31, 2014, we randomly assigned 136 patients to receive brief guided parent-delivered CBT (n=68) or solution-focused brief therapy (n=68). At the primary endpoint assessment (June, 2012, to September, 2014), 40 (59%) children in

The brief family relationship scale: a brief measure of the relationship dimension in family functioning.

Fok, Carlotta Ching Ting; Allen, James; Henry, David

2014-02-01

The Relationship dimension of the Family Environment Scale, which consists of the Cohesion, Expressiveness, and Conflict subscales, measures a person's perception of the quality of his or her family relationship functioning. This study investigates an adaptation of the Relationship dimension of the Family Environment Scale for Alaska Native youth. The authors tested the adapted measure, the Brief Family Relationship Scale, for psychometric properties and internal structure with 284 12- to 18-year-old predominately Yup'ik Eskimo Alaska Native adolescents from rural, remote communities. This non-Western cultural group is hypothesized to display higher levels of collectivism traditionally organized around an extended kinship family structure. Results demonstrate a subset of the adapted items function satisfactorily, a three-response alternative format provided meaningful information, and the subscale's underlying structure is best described through three distinct first-order factors, organized under one higher order factor. Convergent and discriminant validity of the Brief Family Relationship Scale was assessed through correlational analysis.

Sleep disturbances are common among adolescents, but there are no brief interventions to treat them. The objective of this study was to evaluate the effectiveness of a brief semistructured, individually delivered sleep intervention to ameliorate adolescents' sleeping difficulties and lengthen sleep duration. All students aged 16-18 years in a high school were screened for sleeping difficulties and 36 students with the highest sleep problem scores were invited to the intervention. Postintervention improvements were observed on self-reported and actiwatch-registered sleep duration, self-reported sleep quality and sleep latency, perceived stress and anxiety (all p values sleep efficiency and sleep latency did not change (p > 0.05). A brief individual sleep intervention can be effective in lengthening sleep duration and improving subjective sleep quality and well-being among adolescents.

OBJECTIVES: Teaching of clinical pathology to medical students has been ignored in many countries such as Iran. We aim to introduce a practical brief course and its proper timing. MATERIALS AND METHODS: Three groups of medical students from consecutive years of entrance passed a 1.5 working day practical course on the field. Their level of knowledge was assessed by pre- and post-tests. Their idea and satisfaction were gathered by questionnaires. RESULTS: Knowledge of students became significantly higher after the course. Their satisfaction was high. Students in later year of education got significantly higher marks. Most of the students wished such a course should be away from basic sciences period and as near as possible to internship. DISCUSSION: Due to overloaded curriculum of general medicine in Iran, we decided to run a brief practical course of laboratory medicine education for medical students. Although the course was practical, the knowledge of students became higher. Students with more clinical experience and knowledge absorbed more. Being actively involved in the classes lit the enthusiasm of students and made them satisfied with the course. It seemed that the course should be placed in later years of clinical training to get the best uptake and results. PMID:29114552

Social and ethical dimensions of nanoscale science and engineering research.

2006-07-01

Continuing advances in human ability to manipulate matter at the atomic and molecular levels (i.e. nanoscale science and engineering) offer many previously unimagined possibilities for scientific discovery and technological development. Paralleling these advances in the various science and engineering sub-disciplines is the increasing realization that a number of associated social, ethical, environmental, economic and legal dimensions also need to be explored. An important component of such exploration entails the identification and analysis of the ways in which current and prospective researchers in these fields conceptualize these dimensions of their work. Within the context of a National Science Foundation funded Research Experiences for Undergraduates (REU) program in nanomaterials processing and characterization at the University of Central Florida (2002-2004), here I present for discussion (i) details of a "nanotechnology ethics" seminar series developed specifically for students participating in the program, and (ii) an analysis of students' and participating research faculty's perspectives concerning social and ethical issues associated with nanotechnology research. I conclude with a brief discussion of implications presented by these issues for general scientific literacy and public science education policy.

Background Health care providers do not routinely carry out brief counseling for tobacco cessation despite the evidence for its effectiveness. For this intervention to be routinely used, it must be brief, be convenient, require little investment of resources, require little specialized training, and be perceived as efficacious by providers. Technological advances hold much potential for addressing the barriers preventing the integration of brief interventions for tobacco cessation into the he...

Full Text Available Nancy Cantey Banasiak,1 Mikki Meadows-Oliver2 1Pediatric Nurse Practitioner Specialty, Yale University School of Nursing, New Haven, CT, USA; 2University of Connecticut School of Nursing, Storrs, CT, USA Purpose: The primary purpose of this study was to examine the quality of sponsored and unsponsored asthma websites using the Brief DISCERN instrument and to evaluate whether the Health On the Net Code of Conduct (HONcode logo was present, thereby indicating that the site met the criteria. The Internet is an important source of health information for patients and their families. The primary purpose of this study was to examine the quality of sponsored and unsupported asthma websites. A secondary aim was to determine the readability and reading ease of the materials for each website along with the grade level. Methods: We queried seven Internet search engines using the keyword “asthma.” The websites were evaluated using the six-item Brief DISCERN instrument and by ascertaining whether the HONcode quality label was present. The websites were also evaluated for readability employing Flesch-Kincaid grade level and Flesch reading ease tools using Microsoft Office Word 2013 software. Results: A total of 22 unique websites were included in the study. Approximately 68% of the websites reviewed had a Brief DISCERN cutoff score of ≥16. The overall Brief DISCERN scores ranged from 6 to 30, and the mean score was 17.32 (SD =6.71. The Flesch-Kincaid grade level scores ranged from 2.9 to 15.4, and the average reading grade score was 9.49 (SD =2.7. The Flesch reading ease scores ranged from 17 to 82.7, with a mean reading ease score of 53.57 (SD =15.03. Sites with a HONcode quality label had significantly higher Brief DISCERN scores than those without one (t=2.3795; df=20; p=0.02. Conclusion: Brief DISCERN scores revealed that there is quality asthma information for children and their families available on the Internet. The grade level ranged between 2

Marketing of science in the twenty-first century

Trivelpiece, A.

1987-01-01

The author gives a brief review of marketing of science from the 1930's to the present. He discusses the fact that at the present the scientific community is doing a lousy job of marketing and the fact that it is very important that this be reversed because science and technology have become absolutely essential to our future economic health and development. The four steps which he proposes will help with this problem are: (1) government, universities and industry working together to try and insure that there's an adequate basis of curiosity-driven research; (2) scientist making an effort to insure that they have enough political power to be taken seriously; (3) an adjustment to scientist thinking to reflect the fiscal realities of what the next generation of scientific facilities will cost; and (4) a need for public support

Method: The Brief ICF Core Set was slightly adapted to meet the needs of an interdisciplinary rehabilitation medicine team working in a university outpatient clinic and admitting patients referred from primary care. The Core Set categories were made measurable by means of eg, assessment instruments and clinical investigations. The resulting profile was given a workable shape to facilitate rapid understanding of the initial assessment outcome. Results: Individual patients showed different profiles of problems and resources, which facilitated individual rehabilitation planning. At the level of the study group, the profiles for the Core Set component Body Functions showed that most patients had severe impairment in the sensation of pain and exercise tolerance categories of function, but most had resources in the motivation and memory categories of function. Likewise, for the component Activities, most patients had limitations in lifting and carrying objects and remunerative employment, but most had resources in intimate relationships and family relationships. At first, the use of the modified Brief ICF Core Set in the team conference was rather time consuming, but after a couple of months of experience, the team assessment took

Brief Mindfulness Practices for Healthcare Providers - A Systematic Literature Review.

Science.gov (United States)

Gilmartin, Heather; Goyal, Anupama; Hamati, Mary C; Mann, Jason; Saint, Sanjay; Chopra, Vineet

2017-10-01

Mindfulness practice, where an individual maintains openness, patience, and acceptance while focusing attention on a situation in a nonjudgmental way, can improve symptoms of anxiety, burnout, and depression. The practice is relevant for health care providers; however, the time commitment is a barrier to practice. For this reason, brief mindfulness interventions (eg, ≤ 4 hours) are being introduced. We systematically reviewed the literature from inception to January 2017 about the effects of brief mindfulness interventions on provider well-being and behavior. Studies that tested a brief mindfulness intervention with hospital providers and measured change in well-being (eg, stress) or behavior (eg, tasks of attention or reduction of clinical or diagnostic errors) were selected for narrative synthesis. Fourteen studies met inclusion criteria; 7 were randomized controlled trials. Nine of 14 studies reported positive changes in levels of stress, anxiety, mindfulness, resiliency, and burnout symptoms. No studies found an effect on provider behavior. Brief mindfulness interventions may be effective in improving provider well-being; however, larger studies are needed to assess an impact on clinical care. Published by Elsevier Inc.

Fascinating Magnetic Energy Storage Nanomaterials: A Brief Review.

Science.gov (United States)

Sreenivasulu, Kummari V; Srikanth, Vadali V S S

2017-07-10

In this brief review, the importance of nanotechnology in developing novel magnetic energy storage materials is discussed. The discussion covers recent patents on permanent magnetic materials and especially covers processing of permanent magnets (rare-earth and rare-earth free magnets), importance of rare-earth permanent magnets and necessity of rare-earth free permanent magnets. Magnetic energy storage materials are those magnetic materials which exhibit very high energy product (BH)max (where B is the magnetic induction in Gauss (G) whereas H is the applied magnetic field in Oersted (Oe)). (BH)max is the direct measure of the ability of a magnetic material to store energy. In this context, processing of magnetic energy storage composite materials constituted by soft and hard magnetic materials played a predominant role in achieving high (BH)max values due to the exchange coupling phenomenon between the soft and hard magnetic phases within the composite. Magnetic energy storage composites are normally composed of rare-earth magnetic materials as well as rare-earth free magnetic materials. Nanotechnology's influence on the enhancement of energy product due to the exchange coupling phenomenon is of great prominence and therefore discussed in this review.

For the first time, Stephen Hawking turns his gaze inward for a revealing look at his own life and intellectual evolution. My Brief History recounts Stephen Hawking's improbable journey, from his post-war London boyhood to his years of international acclaim and celebrity. Illustrated with rarely seen photographs, this concise, witty and candid account introduces readers to the inquisitive schoolboy whose classmates nicknamed him 'Einstein'; the jokester who once placed a bet with a colleague over the existence of a black hole; and the young husband and father striving to gain a foothold in the world of academia. Writing with humility and humour, Hawking opens up about the challenges that confronted him following his diagnosis of ALS aged twenty-one. Tracing his development as a thinker, he explains how the prospect of an early death urged him onward through numerous intellectual breakthroughs, and talks about the genesis of his masterpiece A Brief History of Time - one of the iconic books of the twentieth century.

This papers presents the findings of a pilot study that examined the impact of a video-based solution-focused brief coaching intervention delivered in conjunction with income tax preparation services at a Volunteer Income Tax Assistance location (n = 212. Individuals receiving tax preparation assistance were randomly assigned to one of four treatment groups: 1 control group; 2 video-based solution-focused brief coaching; 3 discount card incentive; 4 both the video-based solution-focused brief coaching and the discount card incentive. Results of the study indicate that the video-based solution-focused brief coaching intervention increased both the frequency and amount of self-reported savings at tax time. Results also indicate that financial therapy based interventions may be scalable through the use of technology.

Brief debrisoquin administration to assess central dopaminergic function in children.

Science.gov (United States)

Riddle, M A; Shaywitz, B A; Leckman, J F; Anderson, G M; Shaywitz, S E; Hardin, M T; Ort, S I; Cohen, D J

1986-03-17

Central dopaminergic (DA) function in children was assessed by monitoring plasma-free homovanillic acid (pHVA) levels after brief (18 hour) administration with debrisoquin sulfate, a peripherally active antihypertensive agent that blocks peripheral, but not central, HVA production. Brief debrisoquin administration resulted in marked reductions in pHVA in each of six patients studied. In five of the six patients, post-debrisoquin pHVA levels remained relatively stable over the six-hour period of observation. No significant cardiovascular or behavioral side effects of debrisoquin were observed. The brief debrisoquin administration method appears to be a safe, simple, and potentially valid peripheral technique for evaluating aspects of central dopaminergic function in children with neuropsychiatric disorders. Additional work is needed to further establish this method's validity and reliability.

In particular, the focus will be on multiple particle problems at different scales: in biology (e.g. prediction of protein structures), chemistry (e.g. prediction of molecular properties and reactions), and high-energy physics (e.g. detection of exotic particles, jet substructure and tagging, "dark matter and dark knowledge")

Since the middle of 20(th) Century, cognitive science has been recognized as the genuine convergence field for all scientific advances in human mind studies with the mechanisms enabling knowledge. Since then, it has become a multidisciplinary area where several research disciplines and actors have acquired citizenship, allowing new expectations on the scientific study of human uniqueness. Critical assessment of the discussion that the discourse of theoretical biology has been assuming regarding the study of the cognitive phenomenon with special attention to the enactive project and, extensively, to the neuro-phenomenology of Francisco J. Varela. Starting with a brief and synthesized history of cognitive science, we will establish the key principles for understanding the emergence of the enactive paradigm and the "embodied" turn influenced by continental phenomenology in the cognitive science, as well as the general guidelines of Neurophenomenology. The "hard problem" of consciousness still faces several types of reductionism relegating the cognitive issue to a kind of merely rational, individual, abstract and disembodied mechanism, thus strengthening the functionalist paradigm in mind philosophy. A solution to classic dichotomies in mind sciences must start rejecting such assumptions. Copyright © 2012 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España. All rights reserved.

The National Ocean Sciences Bowl: An Effective Model for Engaging High School Students in Ocean Science

Science.gov (United States)

Holloway, A. E.

2016-02-01

The National Ocean Sciences Bowl (NOSB) is an informal high school education program that engages students in ocean and environmental science and exposes them to the breadth of ocean-related careers. The NOSB strives to train the next generation of interdisciplinary capable scientists and build a STEM-literate society that harnesses the power of ocean and climate science to address environmental, economic, and societal issues. Through the NOSB, students not only learn scientific principles, but also apply them to compelling real-world problems. The NOSB provides a richer STEM education and exposes students to ocean science topics they may not otherwise study through classroom curriculum. A longitudinal study that began in 2007 has shown that NOSB participants have an enhanced interest in ocean-related hobbies and environmental stewardship and an increasing number of these students have remained in the STEM pipeline and workforce.While the NOSB is primarily an academic competition, it has evolved since its creation in 1998 to include a variety of practical and professional development components. One of the program enhancements, the Scientific Expert Briefing (SEB), gives students the opportunity to apply what they have studied and think critically about current and ongoing ocean science challenges. The SEB helps students connect their knowledge of ocean science with current and proposed policy initiatives. Students gain significant research, writing, and presentation skills, while enhancing their ability for collaboration and consensus building, all vital workforce skills. Ultimately, the SEB teaches students how to communicate complex scientific research into digestible information for decision-makers and the general public.This poster will examine the impact of the NOSB and its role in strengthening the workforce pipeline through a combination of independent learning, competition, and opportunities for communication skills development.

Brief Adlerian psychodynamic psychotherapy: theoretical issues and process indicators.

Fassino, S; Amianto, F; Ferrero, A

2008-06-01

Brief psychotherapy is gaining interest worldwide, because of its good cost/effectiveness ratio and proved efficacy. The aim of the paper was to describe the brief Adlerian psychodynamic psychotherapy (B-APP): a brief, psychodynamically oriented psychotherapy referring to the individual psychology (IP). The B-APP theory refers to the following paradigms: 1) the individual represents a psychosomatic unity integrated in the social context; 2) the individual needs to build and regulate the image of the self; 3) bond patterns regulate human relationships and represent the symbolic ''fil rouge'' connecting the elements of the life-style. Its objectives are: 1) an at least partial resolution of the focus problem; 2) a decrease or a non-increase of symptoms; 3) a global increase of quality of life. The results depend on intrapsychic and relational changes. Indications are more relative than absolute. The possibility of identifying a meaningful focus is fundamental. The treatment scheme includes 15 sessions subdivided into 5 phases. B-APP offers a technical approach to brief psychotherapy which is suitable in many fields of psychiatry and liaison medicine such as preventive interventions in at-risk subjects, somatopsychic disorders and liaison psychiatry, personality and eating disorders, and treatment of emotionally disturbed children. It was applied as psychotherapeutic approach in some clinical outcome studies about eating disorders and severe personality disorders displaying a good efficacy.

Epidemiologic data indicate most adolescents and adults experience multiple, simultaneous risk behaviors. The purpose of this study is to examine the efficacy of a brief image-based multiple-behavior intervention (MBI) for college students. A total of 303 college students were randomly assigned to: (1) a brief MBI or (2) a standard care control, with a 3-month postintervention follow-up. Omnibus treatment by time multivariate analysis of variance interactions were significant for three of six behavior groupings, with improvements for college students receiving the brief MBI on alcohol consumption behaviors, F(6, 261) = 2.73, p = 0.01, marijuana-use behaviors, F(4, 278) = 3.18, p = 0.01, and health-related quality of life, F(5, 277) = 2.80, p = 0.02, but not cigarette use, exercise, and nutrition behaviors. Participants receiving the brief MBI also got more sleep, F(1, 281) = 9.49, p = 0.00, than those in the standard care control. A brief image-based multiple-behavior intervention may be useful in influencing a number of critical health habits and health-related quality-of-life indicators of college students.

Scientists and Educators: Joining Forces to Enhance Ocean Science Literacy

Science.gov (United States)

Keener-Chavis, P.

2004-12-01

The need for scientists to work with educators to enhance the general public's understanding of science has been addressed for years in reports like Science for All Americans (1990), NSF in a Changing World (1995), Turning to the Sea: America's Ocean Future (1999), Discovering the Earth's Final Frontier, A U.S. Strategy for Ocean Exploration (2000), and most recently, the U.S. Commission on Ocean Policy Report (2004). As reported in The National Science Foundation's Center for Ocean Science Education Excellence (COSEE) Workshop Report (2000), "The Ocean Sciences community did not answer (this) call, even though their discovery that the ocean was a more critical driving force in the natural environment than previously thought possessed great educational significance." It has been further acknowledged that "rapid and extensive improvement of science education is unlikely to occur until it becomes clear to scientists that they have an obligation to become involved in elementary- and secondary-level science (The Role of Scientists in the Professional Development of Science Teachers, National Research Council, 1996.) This presentation will focus on teachers' perceptions of how scientists conduct research, scientists' perceptions of how teachers should teach, and some misconceptions between the two groups. Criteria for high-quality professional development for teachers working with scientists will also be presented, along with a brief overview of the National Oceanic and Atmospheric Administration's Ocean Exploration program efforts to bring teachers and ocean scientists together to further ocean science literacy at the national level through recommendations put forth in the U.S. Commission on Ocean Policy Report (2004).

SciNews: Incorporating Science Current Events in 21st Century Classrooms

Science.gov (United States)

DiMaggio, E.

2011-12-01

Middle school students are instructed with the aid of textbooks, lectures, and activities to teach topics that satisfy state standards. However, teaching materials created to convey standard-aligned science concepts often leave students asking how the content relates to their lives and why they should be learning it. Conveying relevance is important for student learning and retention, especially in science where abstract concepts can often be incorrectly perceived as irrelevant. One way to create an educational link between classroom content and everyday life is through the use of scientific current events. Students read, hear, and watch media coverage of natural events (such as the 2011 earthquake and tsunami in Japan), but do not necessarily relate the scientific information from media sources to classroom studies. Taking advantage of these brief 'teachable moments'--when student interest is high--provides a valuable opportunity to make classroom-to-everyday life associations and to incorporate inquiry based learning. To address this need, I create pre-packaged current event materials for middle to high school teachers that align to state standards, and which are short, effective, and easy to implement in the classroom. Each lesson takes approximately 15-30 minutes to implement, allowing teachers time to facilitate brief but meaningful discussions. I assemble materials within approximately one week of the regional or global science event, consisting of short slide shows, maps, videos, pictures, and real-time data. I use a listserv to send biweekly emails to subscribed instructors containing the current event topic and a link to download the materials. All materials are hosted on the Arizona State University Education Outreach SciNews website (http://sese.asu.edu/teacher-resources) and are archived. Currently, 285 educators subscribe to the SciNews listserv, representing 36 states and 19 countries. In order to assess the effectiveness and usefulness of Sci

Knowledge systems and the colonial legacies in African science education

Ziegler, John R.; Lehner, Edward

2017-10-01

This review surveys Femi Otulaja and Meshach Ogunniyi's, Handbook of research in science education in sub-Saharan Africa, Sense, Rotterdam, 2017, noting the significance of the theoretically rich content and how this book contributes to the field of education as well as to the humanities more broadly. The volume usefully outlines the ways in which science education and scholarship in sub-Saharan Africa continue to be impacted by the region's colonial history. Several of the chapters also enumerate proposals for teaching and learning science and strengthening academic exchange. Concerns that recur across many of the chapters include inadequate implementation of reforms; a lack of resources, such as for classroom materials and teacher training; and the continued and detrimental linguistic, financial, and ideological domination of African science education by the West. After a brief overview of the work and its central issues, this review closely examines two salient chapters that focus on scholarly communications and culturally responsive pedagogy. The scholarly communication section addresses the ways in which African science education research may in fact be too closely mirroring Western knowledge constructions without fully integrating indigenous knowledge systems in the research process. The chapter on pedagogy makes a similar argument for integrating Western and indigenous knowledge systems into teaching approaches.

West Siberia contains the largest extent of wetlands in the world, including large peat deposits; the wetland area is equivalent to 27% of the total area of West Siberia. This study used inverse modeling to refine emissions estimates for West Siberia using atmospheric CH{sub 4} observations and two wetland CH{sub 4} emissions inventories: (1) the global wetland emissions dataset of the NASA Goddard Institute for Space Studies (the GISS inventory), which includes emission seasons and emission rates based on climatology of monthly surface air temperature and precipitation, and (2) the West Siberian wetland emissions data (the Bc7 inventory), based on in situ flux measurements and a detailed wetland classification. The two inversions using the GISS and Bc7 inventories estimated annual mean flux from West Siberian wetlands to be 2.9 {+-} 1.7 and 3.0 {+-} 1.4 Tg yr{sup -1}, respectively, which are lower than the 6.3 Tg yr{sup -1} predicted in the GISS inventory, but similar to those of the Bc7 inventory (3.2 Tg yr{sup -1}). The well-constrained monthly fluxes and a comparison between the predicted CH{sub 4} concentrations in the two inversions suggest that the Bc7 inventory predicts the seasonal cycle of West Siberian wetland CH{sub 4} emissions more reasonably, indicating that the GISS inventory predicts more emissions from wetlands in northern and middle taiga.

Climate and transboundary water management issues

Bjonback, D.

1991-01-01

The potential effects of climate change on transboundary river systems, major water uses, interjurisdictional arrangements, and water issues affecting water management in the Great Plains of Canada are discussed. Three atmospheric general circulation models (GCM) have been applied for a two times carbon dioxide concentration scenario for the Saskatchewan River system. The models were the Goddard Institute for Space Studies (GISS) model, the Geophysical Fluid Dynamics Laboratory (GFDL) model, and the Oregon State University (OSU) model. For all models, soil moisture on the plains was reduced. The GISS model predicted slightly higher runoff for plains-originating streams, and a substantial increase in runoff (32%) in the Rockies. The GFDL model predicted lower runoffs in the plains and Rockies, with some locations near the Alberta-Saskatchewan border indicating zero runoff. The OSU model results generally bracketed the GISS and GFDL results, with total runoff approximating 1951-1980 mean. The GISS model indicated an increase in net basin supply of 28%, while the GFDL model, due to lower runoff and high soil moisture defecits, showed a decrease of 38%. For policy making, monitoring, and research, the GFDL model results can provide important guidelines. Greater attention to demand management and conservation will have short-term benefits in stretching the limited water resource base to support a larger economy, while providing flexibility to cope with future climate as it evolves. 1 ref

Many Iraqi refugees suffer from posttraumatic stress. Efficient, culturally sensitive interventions are needed, and so we adapted narrative exposure therapy into a brief version (brief NET) and tested its effects in a sample of traumatized Iraqi refugees. Iraqi refugees in the United States reporting elevated posttraumatic stress (N = 63) were randomized to brief NET or waitlist control conditions in a 2:1 ratio; brief NET was 3 sessions, conducted individually, in Arabic. Positive indicators (posttraumatic growth and well-being) and symptoms (posttraumatic stress, depressive, and somatic) were assessed at baseline and 2- and 4-month follow-up. Treatment participation (95.1% completion) and study retention (98.4% provided follow-up data) were very high. Significant condition by time interactions showed that those receiving brief NET had greater posttraumatic growth (d = 0.83) and well-being (d = 0.54) through 4 months than controls. Brief NET reduced symptoms of posttraumatic stress (d = -0.48) and depression (d = -0.46) more, but only at 2 months; symptoms of controls also decreased from 2 to 4 months, eliminating condition differences at 4 months. Three sessions of brief NET increased growth and well-being and led to symptom reduction in highly traumatized Iraqi refugees. This preliminary study suggests that brief NET is both acceptable and potentially efficacious in traumatized Iraqi refugees. Copyright © 2014 International Society for Traumatic Stress Studies.

Health care is a high-risk industry. To improve communication about daily events and begin the journey toward a high reliability organization, the Riley Hospital for Children at Indiana University Health implemented a daily safety brief. Various departments in our children's hospital were asked to participate in a daily safety brief, reporting daily events and unexpected outcomes within their scope of responsibility. Participants were surveyed before and after implementation of the safety brief about communication and awareness of events in the hospital. The length of the brief and percentage of departments reporting unexpected outcomes were measured. The analysis of the presurvey and the postsurvey showed a statistically significant improvement in the questions related to the awareness of daily events as well as communication and relationships between departments. The monthly mean length of time for the brief was 15 minutes or less. Unexpected outcomes were reported by 50% of the departments for 8 months. A daily safety brief can be successfully implemented in a children's hospital. Communication between departments and awareness of daily events were improved. Implementation of a daily safety brief is a step toward becoming a high reliability organization.

Fallucco, Elise M; Wysocki, Tim; James, Lauren; Kozikowski, Chelsea; Williams, Andre; Gleason, Mary M

Brief, well-validated instruments are needed to facilitate screening for early childhood behavioral and emotional problems (BEPs). The objectives of this study were to empirically reduce the length of the Early Childhood Screening Assessment (ECSA) and to assess the validity and reliability of this shorter tool. Using caregiver ECSA responses for 2467 children aged 36 to 60 months seen in primary care, individual ECSA items were ranked on a scale ranging from "absolutely retain" to "absolutely delete." Items were deleted sequentially beginning with "absolutely delete" and going up the item prioritization list, resulting in 35 shorter versions of the ECSA. A separate primary care sample (n = 69) of mothers of children aged 18 to 60 months was used to determine the sensitivity and specificity of each shorter ECSA version using psychiatric diagnosis on the Diagnostic Infant and Preschool Assessment as the gold standard. The version with the optimal balance of sensitivity, specificity, and length was selected as the Brief ECSA. Associations between Brief ECSA scores and other pertinent measures were evaluated to estimate reliability and validity. A 22-item measure reflected the best combination of brevity, sensitivity and specificity. A cutoff score of 9 or higher on the 22-item Brief ECSA demonstrated acceptable sensitivity (89%) and specificity (85%) for predicting a psychiatric diagnosis. Brief ECSA scores correlated significantly and in expected directions with scores on pertinent measures and with demographic variables. The results indicate that the Brief ECSA has sound psychometric properties for identifying young children with BEPs in primary care.

A brief measure of attitudes toward mixed methods research in psychology.

Roberts, Lynne D; Povee, Kate

2014-01-01

The adoption of mixed methods research in psychology has trailed behind other social science disciplines. Teaching psychology students, academics, and practitioners about mixed methodologies may increase the use of mixed methods within the discipline. However, tailoring and evaluating education and training in mixed methodologies requires an understanding of, and way of measuring, attitudes toward mixed methods research in psychology. To date, no such measure exists. In this article we present the development and initial validation of a new measure: Attitudes toward Mixed Methods Research in Psychology. A pool of 42 items developed from previous qualitative research on attitudes toward mixed methods research along with validation measures was administered via an online survey to a convenience sample of 274 psychology students, academics and psychologists. Principal axis factoring with varimax rotation on a subset of the sample produced a four-factor, 12-item solution. Confirmatory factor analysis on a separate subset of the sample indicated that a higher order four factor model provided the best fit to the data. The four factors; 'Limited Exposure,' '(in)Compatibility,' 'Validity,' and 'Tokenistic Qualitative Component'; each have acceptable internal reliability. Known groups validity analyses based on preferred research orientation and self-rated mixed methods research skills, and convergent and divergent validity analyses based on measures of attitudes toward psychology as a science and scientist and practitioner orientation, provide initial validation of the measure. This brief, internally reliable measure can be used in assessing attitudes toward mixed methods research in psychology, measuring change in attitudes as part of the evaluation of mixed methods education, and in larger research programs.

In the UK, GPs and practice nurses selectively provide brief alcohol interventions to risk drinkers. GPs' provision of a brief alcohol intervention can be predicted by patient characteristics, practitioner characteristics and structural factors such as the features of the practice and how it is organized. However, much less is known about possible modifiers of nurse practice. Our aim was to investigate if patient characteristics, nurse characteristics and practice factors influence provision of a brief alcohol intervention by practice nurses in primary health care. One hundred and twenty-eight practice nurses who had implemented a brief alcohol intervention programme in a previous trial based in the North of England were requested to screen adults presenting to their surgery and follow a structured protocol to give a brief intervention (5 min of advice plus an information booklet) to all 'risk' drinkers. Anonymized carbon copies of 5541 completed Alcohol Use Disorders Identification Test (AUDIT) screening questionnaires were collected after a 3-month implementation period and analysed by logistic regression analysis. Although AUDIT identified 1500 'risk' drinkers, only 926 (62%) received a brief intervention. Logistic regression modelling showed that patients' risk status as measured by AUDIT score was the most influential predictor of a brief intervention by practice nurses. However, risk drinkers who were most likely to receive a brief intervention were male. Patients' age or social class did not independently predict a brief intervention. The multilevel model was unable to identify any independent nurse characteristics that could predict a brief intervention, but indicated significant variation between nurses in their tendency to offer the intervention to patients. No structural factors were found to be positively associated with selective provision. Patient and nurse factors contributed to the selective provision of a brief intervention in primary care. If

This paper reviews efforts of the Center for Nanotechnology in Society at Arizona State University (CNS-ASU) to begin to build capacity for public engagement with science in the United States. First, the paper sets a context in the US of the current challenges to democracy and for science. It then reviews the literature on the accomplishments of the National Citizens' Technology Forum (NCTF) on nanotechnology and human enhancement, held in 2008, as well as some caveats that emerged from that enterprise. It concludes with a brief discussion of two kinds of activities - participation in the World Wide Views process organized by the Danish Board of Technology, and methodological innovations that include more concrete and experiential modes of engagement - that have spun off from the NCTF.

Learning science as a potential new source of understanding and improvement for continuing education and continuing professional development.

Learning science is an emerging interdisciplinary field that offers educators key insights about what happens in the brain when learning occurs. In addition to explanations about the learning process, which includes memory and involves different parts of the brain, learning science offers effective strategies to inform the planning and implementation of activities and programs in continuing education and continuing professional development. This article provides a brief description of learning, including the three key steps of encoding, consolidation and retrieval. The article also introduces four major learning-science strategies, known as distributed learning, retrieval practice, interleaving, and elaboration, which share the importance of considerable practice. Finally, the article describes how learning science aligns with the general findings from the most recent synthesis of systematic reviews about the effectiveness of continuing medical education.

Many science and research skills are taught by osmosis in graduate programs with the expectation that students will develop good communication skills (speaking, writing, and networking) by observing others, attending meetings, and self reflection. A new National Science Foundation Graduate Teaching Fellows in K- 12 Education (GK-12; http://ehrweb.aaas.org/gk12new/) program at UCLA (SEE-LA; http://measure.igpp.ucla.edu/GK12-SEE-LA/overview.html ) attempts to make the development of good communication skills an explicit part of the graduate program of science and engineering students. SEE-LA places the graduate fellows in two pairs of middle and high schools within Los Angeles to act as scientists-in- residence. They are partnered with two master science teachers and spend two-days per week in the classroom. They are not student teachers, or teacher aides, but scientists who contribute their content expertise, excitement and experience with research, and new ideas for classroom activities and lessons that incorporate inquiry science. During the one-year fellowship, the graduate students also attend a year-long Preparing Future Faculty seminar that discusses many skills needed as they begin their academic or research careers. Students are also required to include a brief (two-page) summary of their research that their middle or high school students would be able to understand as part of their published thesis. Having students actively thinking about and communicating their science to a pre-college audience provides important science communication training and helps contribute to science education. University and local pre- college school partnerships provide an excellent opportunity to support the development of graduate student communication skills while also contributing significantly to the dissemination of sound science to K-12 teachers and students.

2000-01-01

Four of the most important applications of the high pressure technique in today's science are: (1) to help identify the materials which reside deep within our earth or other heavenly bodies and determine their properties, (2) to uncover underlying systematics and critically test theoretical models, (3) to synthesize novel and useful materials not readily available by other means, and (4) to determine the effect of pressure on living organisms and explore the conditions favorable for the origin of life itself. High pressure studies currently enjoy an increasing popularity which is fueled by recent advances in the notably difficult experimental techniques. In this paper I will attempt to capture some of the current excitement in this field by offering brief synopses of selected experiments in the basic, materials, and life sciences

Miyake, Akira; Kost-Smith, Lauren E; Finkelstein, Noah D; Pollock, Steven J; Cohen, Geoffrey L; Ito, Tiffany A

2010-11-26

In many science, technology, engineering, and mathematics disciplines, women are outperformed by men in test scores, jeopardizing their success in science-oriented courses and careers. The current study tested the effectiveness of a psychological intervention, called values affirmation, in reducing the gender achievement gap in a college-level introductory physics class. In this randomized double-blind study, 399 students either wrote about their most important values or not, twice at the beginning of the 15-week course. Values affirmation reduced the male-female performance and learning difference substantially and elevated women's modal grades from the C to B range. Benefits were strongest for women who tended to endorse the stereotype that men do better than women in physics. A brief psychological intervention may be a promising way to address the gender gap in science performance and learning.

From efficacy to effectiveness and beyond: what next for brief interventions in primary care?

Directory of Open Access Journals (Sweden)

Amy eO'Donnell

2014-08-01

Full Text Available Background: Robust evidence supports the effectiveness of screening and brief alcohol interventions in primary healthcare. However lack of understanding about their ‘active ingredients’ and concerns over the extent to which current approaches remain faithful to their original theoretical roots, has led some to demand a cautious approach to future roll-out pending further research. Against this background, this paper provides a timely overview of the development of the brief alcohol intervention evidence base in order to assess the extent to which it has achieved the four key levels of intervention research: efficacy; effectiveness; implementation; and demonstration.Methods: Narrative overview based on:(1 results of a review of systematic reviews and meta-analyses of the effectiveness of brief alcohol intervention in primary healthcare;(2 synthesis of the findings of key additional primary studies on the improvement and evaluation of brief alcohol intervention implementation in routine primary healthcare.Results: The brief intervention field seems to constitute an almost perfect example of the evaluation of a complex intervention. Early evaluations of screening and brief intervention approaches included more tightly controlled efficacy trials and have been followed by more pragmatic trials of effectiveness in routine clinical practice. Most recently, attention has shifted to dissemination, implementation and wider-scale roll-out. However, delivery in routine primary health remains inconsistent, with an identified knowledge gap around how to successfully embed brief alcohol intervention approaches in mainstream care, and as yet unanswered questions concerning what specific intervention component prompt the positive changes in alcohol consumption.Conclusion: Both the efficacy and effectiveness of brief alcohol interventions have been comprehensively demonstrated, and intervention effects seem replicable and stable over time, and across

The development, operation, and analysis of data from cubesats can promote science education and spur technology utilization in emerging and developing nations. This platform offers uniquely low construction and launch costs together with a comparative ubiquity of launch providers; factors that have led more than 80 universities and several emerging nations to develop programs in this field. Their small size and weight enables cubesats to “piggyback” on rocket launches and accompany orbiters travelling to Moon and Mars. It is envisaged that constellations of cubesats will be used for larger science missions. We present a brief history, technology overview, and summary of applications in science and industry for these small satellites. Cubesat technical success stories are offered along with a summary of pitfalls and challenges encountered in both developed and emerging nations. A discussion of economic and public policy issues aims to facilitate the decision-making process for those considering utilization of this unique technology.

The third meeting of the Tank Waste Science Panel was held September 13--14, 1990. Science Panel members were briefed on the August 5, 1990, gas release from tank 241-101-SY (commonly denoted 101-SY), synthetic waste experiments to investigate gas generation and crust behavior in the tank, computer simulations of the thermal behavior of the waste in the tank, and calculations of gas generation based on radiolytic chemistry in alkaline solutions. Data from tanks 103-SY and 103-AN were presented, but it was decided not to divert attention from tank 101-SY at this time by taking additional samples from 103-SY or 103-AN. Science Panel members recommended that multiple groups begin a concerted experimental effort to understand the chemical and physical mechanisms involved in the tank. The understanding, along with the tank model, can then be used to determine the effectiveness of a particular mitigation method before using the method in tank 101-SY. 1 tab

Use of reactor produced radionuclides is popular in life sciences. However, cyclotron production of proton rich radionuclides are being more focused in recent times. These radionuclides have already gained attention in various fields, including life sciences, provided they are obtained in pure form. This article is a representative brief of our contributions in generating nuclear data for the production of proton rich radionuclides of terbium, astatine, technetium, ruthenium, cadmium, niobium, zirconium, rhenium, etc., which may have application in clinical, biological, agriculture studies or in basic research. The chemical data required to separate the product isotopes from the corresponding target matrix have been presented along with a few propositions of radiopharmaceuticals. It also emphasizes on the development of simple empirical technique, based on the nuclear reaction model analysis, to generate reliable nuclear data for the estimation of yield and angular distribution of emitted neutrons and light charged particles from light as well as heavy ion induced reactions on thick stopping targets. These data bear utmost important in radiation dosimetry. (author)

Alcohol misuse is substantially influenced by social factors, but systematic assessments of social network drinking are typically lengthy. The goal of the present study was to provide further validation of a brief measure of social network alcohol use, the Brief Alcohol Social Density Assessment (BASDA), in a sample of emerging adults. Specifically, the study sought to examine the BASDA's convergent, criterion, and incremental validity in relation to well-established measures of drinking motives and problematic drinking. Participants were 354 undergraduates who were assessed using the BASDA, the Alcohol Use Disorders Identification Test (AUDIT), and the Drinking Motives Questionnaire. Significant associations were observed between the BASDA index of alcohol-related social density and alcohol misuse, social motives, and conformity motives, supporting convergent validity. Criterion-related validity was supported by evidence that significantly greater alcohol involvement was present in the social networks of individuals scoring at or above an AUDIT score of 8, a validated criterion for hazardous drinking. Finally, the BASDA index was significantly associated with alcohol misuse above and beyond drinking motives in relation to AUDIT scores, supporting incremental validity. Taken together, these findings provide further support for the BASDA as an efficient measure of drinking in an individual's social network. Methodological considerations as well as recommendations for future investigations in this area are discussed.

What are the implications for policy makers? A systematic review of the cost-effectiveness of screening and brief interventions for alcohol misuse in primary care.

2014-09-01

Full Text Available IntroductionThe efficacy of screening and brief interventions (SBI for excessive alcohol use in primary care is well established; however evidence on their cost-effectiveness is limited. A small number of previous reviews have concluded that SBI programmes are likely to be cost-effective, but these results are equivocal and important questions around the cost-effectiveness implications of key policy decisions such as staffing choices for delivery of SBIs and the intervention duration remain unanswered. MethodsStudies reporting both the costs and a measure of health outcomes of programmes combining screening and brief interventions in primary care were identified by searching MEDLINE, EMBASE, Econlit, the Cochrane Library Database (including NHS EED, CINAHL, PsycINFO, Assia and the Social Science Citation Index and Science Citation Index via Web of Knowledge. Included studies have been stratified both by delivery staff and intervention duration and assessed for quality using the Drummond checklist for economic evaluations.ResultsThe search yielded a total of 23 papers reporting the results of 22 distinct studies. There was significant heterogeneity in methods and outcome measures between studies; however almost all studies reported SBI programmes to be cost-effective. There was no clear evidence that either the duration of the intervention or the delivery staff used had a substantial impact on this result.ConclusionThis review provides strong evidence that SBI programmes in primary care are a cost-effective option for tackling alcohol misuse.

Current fundamental science challenges in low temperature plasma science that impact energy security and international competitiveness

Science.gov (United States)

Hebner, Greg

2010-11-01

Products and consumer goods that utilize low temperature plasmas at some point in their creation touch and enrich our lives on almost a continuous basis. Examples are many but include the tremendous advances in microelectronics and the pervasive nature of the internet, advanced material coatings that increase the strength and reliability of products from turbine engines to potato chip bags, and the recent national emphasis on energy efficient lighting and compact fluorescent bulbs. Each of these products owes their contributions to energy security and international competiveness to fundamental research investments. However, it would be a mistake to believe that the great commercial success of these products implies a robust understanding of the complicated interactions inherent in plasma systems. Rather, current development of the next generation of low temperature plasma enabled products and processes is clearly exposing a new set of exciting scientific challenges that require leaps in fundamental understanding and interdisciplinary research teams. Emerging applications such as liquid-plasma systems to improve water quality and remediate hazardous chemicals, plasma-assisted combustion to increase energy efficiency and reduce emissions, and medical applications promise to improve our lives and the environment only if difficult science questions are solved. This talk will take a brief look back at the role of low temperature plasma science in enabling entirely new markets and then survey the next generation of emerging plasma applications. The emphasis will be on describing the key science questions and the opportunities for scientific cross cutting collaborations that underscore the need for increased outreach on the part of the plasma science community to improve visibility at the federal program level. This work is supported by the DOE, Office of Science for Fusion Energy Sciences, and Sandia National Laboratories, a multi-program laboratory managed and operated

Creswell, J David; Pacilio, Laura E; Lindsay, Emily K; Brown, Kirk Warren

To test whether a brief mindfulness meditation training intervention buffers self-reported psychological and neuroendocrine responses to the Trier Social Stress Test (TSST) in young adult volunteers. A second objective evaluates whether pre-existing levels of dispositional mindfulness moderate the effects of brief mindfulness meditation training on stress reactivity. Sixty-six (N=66) participants were randomly assigned to either a brief 3-day (25-min per day) mindfulness meditation training or an analytic cognitive training control program. All participants completed a standardized laboratory social-evaluative stress challenge task (the TSST) following the third mindfulness meditation or cognitive training session. Measures of psychological (stress perceptions) and biological (salivary cortisol, blood pressure) stress reactivity were collected during the social evaluative stress-challenge session. Brief mindfulness meditation training reduced self-reported psychological stress reactivity but increased salivary cortisol reactivity to the TSST, relative to the cognitive training comparison program. Participants who were low in pre-existing levels of dispositional mindfulness and then received mindfulness meditation training had the greatest cortisol reactivity to the TSST. No significant main or interactive effects were observed for systolic or diastolic blood pressure reactivity to the TSST. The present study provides an initial indication that brief mindfulness meditation training buffers self-reported psychological stress reactivity, but also increases cortisol reactivity to social evaluative stress. This pattern may indicate that initially brief mindfulness meditation training fosters greater active coping efforts, resulting in reduced psychological stress appraisals and greater cortisol reactivity during social evaluative stressors.

This special issue provides examples of how qualitative and mixed methods research approaches can be used in dissemination and implementation science. In this introductory article, we provide a brief rationale for why and how qualitative and mixed methods approaches can be useful in moving the field forward. Specifically, we provide a brief primer on common qualitative methods, including a review of guidelines provided by the National Institutes of Health. Next, we introduce the six articles in the issue. The first of the articles by Palinkas represents a more thorough and authoritative discussion related to qualitative methods, using the other five articles in the issue (and other published works) as examples. The remaining five articles are empirical and/or descriptive articles of recently completed or ongoing qualitative or mixed methods studies related to dissemination and implementation of evidence-based practices for children and adolescents.

A brief measure of attitudes toward mixed methods research in psychology

The adoption of mixed methods research in psychology has trailed behind other social science disciplines. Teaching psychology students, academics, and practitioners about mixed methodologies may increase the use of mixed methods within the discipline. However, tailoring and evaluating education and training in mixed methodologies requires an understanding of, and way of measuring, attitudes toward mixed methods research in psychology. To date, no such measure exists. In this article we present the development and initial validation of a new measure: Attitudes toward Mixed Methods Research in Psychology. A pool of 42 items developed from previous qualitative research on attitudes toward mixed methods research along with validation measures was administered via an online survey to a convenience sample of 274 psychology students, academics and psychologists. Principal axis factoring with varimax rotation on a subset of the sample produced a four-factor, 12-item solution. Confirmatory factor analysis on a separate subset of the sample indicated that a higher order four factor model provided the best fit to the data. The four factors; ‘Limited Exposure,’ ‘(in)Compatibility,’ ‘Validity,’ and ‘Tokenistic Qualitative Component’; each have acceptable internal reliability. Known groups validity analyses based on preferred research orientation and self-rated mixed methods research skills, and convergent and divergent validity analyses based on measures of attitudes toward psychology as a science and scientist and practitioner orientation, provide initial validation of the measure. This brief, internally reliable measure can be used in assessing attitudes toward mixed methods research in psychology, measuring change in attitudes as part of the evaluation of mixed methods education, and in larger research programs.

Climate is vital. Earth is only habitable due to the atmosphere&oceans' distribution of energy. Our Greenhouse Gas emissions shift overall the balance between absorbed and emitted radiation causing Global Warming. How much of these emissions are stored in the ocean vs. entering the atmosphere to cause warming and how the extra heat is distributed depends on atmosphere&ocean dynamics, which we must understand to know risks of both progressive Climate Change and Climate Variability which affect us all in many ways including extreme weather, floods, droughts, sea-level rise and ecosystem disruption. Citizens must be informed to make decisions such as "business as usual" vs. mitigating emissions to avert catastrophe. Simulations of Climate Change provide needed knowledge but in turn need reliable parameterizations of key physical processes, including ocean mixing, which greatly impacts transport&storage of heat and dissolved CO2. The turbulence group at NASA-GISS seeks to use physical theory to improve parameterizations of ocean mixing, including smallscale convective, shear driven, double diffusive, internal wave and tidal driven vertical mixing, as well as mixing by submesoscale eddies, and lateral mixing along isopycnals by mesoscale eddies. Medgar Evers undergraduates aid NASA research while learning climate science and developing computer&math skills. We write our own programs in MATLAB and FORTRAN to visualize and process output of ocean simulations including producing statistics to help judge impacts of different parameterizations on fidelity in reproducing realistic temperatures&salinities, diffusivities and turbulent power. The results can help upgrade the parameterizations. Students are introduced to complex system modeling and gain deeper appreciation of climate science and programming skills, while furthering climate science. We are incorporating climate projects into the Medgar Evers college curriculum. The PI is both a member of the turbulence group at

Social media for informal science learning in China: A case study

2014-09-01

Full Text Available This article reports a case study on a popular informal science learning community via social media in China, named GuoKr (meaning “nutshell” in English. Data were collected through a variety of Chinese social media and social networking sites, web-based community portals, and discussion boards. Content analyses and data mining were conducted to investigate how GuoKr successfully attracted and engaged public in informal learning on scientific topics in particular. The study found three key characteristics that contributed to the success of such learning communities: (a utilizing a variety of social media to empower participants with just-in-time, accidental learning opportunities; (b daily tweets related to emerging or ongoing social events or hot topics to provide brief but intriguing knowledge “bites”, which often leads to extended readings and related resources; and (c the integration of social media and traditional face-to-face local events to engage the public in science-related learning and knowledge sharing. Practical and research implications are discussed with suggestions for future research as related to ubiquitous learning communities for informal science learning.

Brief Assessment of Krsko NPP Decommissioning Costs

The first part of the paper gives a brief description of decommissioning scenarios and models of financing the decommissioning of NPPs. The second part contains a review of decommissioning costs for certain PWR plants with a brief description of methods used for that purpose. The third part of the paper the authors dedicated to the assessment of decommissioning costs for Krsko NPP. It does not deal with ownership relations and obligations ensuing from them. It starts from the simple point that decommissioning is an structure of the decommissioning fund is composed of three basic cost items of which the first refers to radioactive waste management, the second to storage and disposal of the spent nuclear fuel and the third to decommissioning itself. The assessment belongs to the category of preliminary activities and as such has a limited scope and meaning. Nevertheless, the authors believe that it offers a useful insight into the basic costs that will burden the decommissioning fund of Krsko NPP. (author)

The aim of this study was to test the effects of brief strategic therapy in people with social phobia distinguished by the presence or absence of DSM anxious personality disorder. A group of 120 outpatients with social phobia, 60 of them with comorbid DSM anxious personality disorder, were randomly assigned to 10 weeks of brief strategic therapy or minimal supportive therapy. Outcome analyses were conducted on the intent-to-treat sample at posttreatment and 3-month follow-up using self-report interpersonal sensitivity and phobic anxiety measures, and at 6-month follow-up using social phobia diagnostic status. Brief strategic therapy was superior to minimal supportive therapy in patients with social phobia only. It was not significantly better in patients with comorbid personality disorder. It was concluded that 10 weeks of brief strategic therapy shows promise as a cost-effective method for management of social phobia. It has limited value as a method for management of social phobia with personality disorder.
