    2008-05-01

    Building on previous experience in capacity building for ocean observations, the Nippon Foundation (NF) and the Partnership for Observations of the Global Oceans (POGO) have announced a new Centre of Excellence (C of E) at the Bermuda Institute of Ocean Sciences (BIOS). The goals of the C of E are to expand the world-wide capacity and expertise to observe the oceans and to expand capacity-building projects and promote international collaboration and networking in ocean sciences. Over the past 104 years, BIOS has built a global reputation in blue-water oceanography, coral reef ecology, and the relationships between ocean health and human health coupled with high quality education programmes that provide direct, hands-on experience with BIOS-based research. The C of E at BIOS will build upon this model to establish a new, graduate-level education and training programme in operational oceanography. The 10 month Programme will offer course modules in ocean disciplines with a focus on observatory sciences complemented by hands-on training in observational methods and techniques based on the multi-disciplinary expertise of BIOS and BIOS-affiliated scientists who direct ongoing, ocean observational programmes such as: - Hydrostation S, since 1954; - Bermuda Atlantic Time-series Study, since 1988; - Oceanic Flux Program sediment trap time-series, since 1978; - Bermuda Test-Bed and Science Mooring, since 1994; - Bermuda Microbial Observatory, since 1997; - Bermuda Bio-Optics Program, since 1992; - Atmospheric chemistry and air-sea fluxes, since 1990 Additional areas of BIOS research expertise will be incorporated in the C of E to broaden the scope of education and training. These include the nearshore observational network of the BIOS Marine Environmental Program and the environmental air-water chemistry network of the Bermuda Environmental Quality Program. A key resource of the C of E is the newly acquired 168 ft. research vessel, the RV Atlantic Explorer, which was specifically designed to provide for ocean research and education (e.g., sufficient berths for scientists and the NF- POGO Scholars; an education-specific classroom). The Atlantic Explorer will serve as a unique platform for the NF-POGO Scholars to gain hands-on, at-sea experience as participants on all scheduled research cruises. The NF-POGO Scholars will take courses that focus on the theoretical and policy side of observational oceanography and participate in a Core Skills module that emphasizes numeracy, data analysis, science management, and written and oral scientific communication. There will be one Regional Training Programme for a Developing Country each year, focused on local issues and how to resolve them. The course is open to 10 participants from developing countries (or countries with economies in transition). NF- POGO Scholars must have at least a first degree in science. Preference will be given to applicants who currently hold a position in a research or academic institution in a developing country and anticipate returning to the country after the training period. Candidates must demonstrate immediate relevance of their training to on-going or planned ocean observations in their home country.

  6. Using Oceanography to Support Active Learning

    NASA Astrophysics Data System (ADS)

    Byfield, V.

    2012-04-01

    Teachers are always on the lookout for material to give their brightest students, in order to keep them occupied, stimulated and challenged, while the teacher gets on with helping the rest. They are also looking for material that can inspire and enthuse those who think that school is 'just boring!' Oceanography, well presented, has the capacity to do both. As a relatively young science, oceanography is not a core curriculum subject (possibly an advantage), but it draws on the traditional sciences of biology, chemistry, physic and geology, and can provide wonderful examples for teaching concepts in school sciences. It can also give good reasons for learning science, maths and technology. Exciting expeditions (research cruises) to far-flung places; opportunities to explore new worlds, a different angle on topical debates such as climate change, pollution, or conservation can bring a new life to old subjects. Access to 'real' data from satellites or Argo floats can be used to develop analytical and problem solving skills. The challenge is to make all this available in a form that can easily be used by teachers and students to enhance the learning experience. We learn by doing. Active teaching methods require students to develop their own concepts of what they are learning. This stimulates new neural connections in the brain - the physical manifestation of learning. There is a large body of evidence to show that active learning is much better remembered and understood. Active learning develops thinking skills through analysis, problem solving, and evaluation. It helps learners to use their knowledge in realistic and useful ways, and see its importance and relevance. Most importantly, properly used, active learning is fun. This paper presents experiences from a number of education outreach projects that have involved the National Oceanography Centre in Southampton, UK. All contain some element of active learning - from quizzes and puzzles to analysis of real data from satellites and Argo floats - all combined with background information about the Ocean. Many also aim to inspire and enthuse, by bringing in the human and personal, for example through blogs and Q/A sessions. This presentation takes a look at what has worked, and what may perhaps have been a little less successful.

    Abbott, M. R.

    1984-01-01

    Within the framework of global biogeochemical cycles and ocean productivity, there are two areas that will be of particular interest to biological oceanography in the 1990s. The first is the mapping in space time of the biomass and productivity of phytoplankton in the world ocean. The second area is the coupling of biological and physical processes as it affects the distribution and growth rate of phytoplankton biomass. Certainly other areas will be of interest to biological oceanographers, but these two areas are amenable to observations from satellites. Temporal and spatial variability is a regular feature of marine ecosystems. The temporal and spatial variability of phytoplankton biomass and productivity which is ubiquitous at all time and space scales in the ocean must be characterized. Remote sensing from satellites addresses these problems with global observations of mesocale (2 to 20 days, 10 to 200 km) features over a long period of time.

    1979-01-01

    The evolution in Europe of the flexible walled test section, as applied to two dimensional testing at low and transonic speeds, is traced from its beginnings at NPL, London, in the early 1940's, and is shown to lead logically to the latest version now nearing completion at Southampton University. The principal changes that have taken place are improvements in the methods of choosing wall contours such that they rapidly follow appropriate streamlines, and reductions in the depth of test sections. The latest transonic test section presently under assembly at Southampton has, as its principal new feature, the facility for the automation of wall streamlining with the aid of an on-line computer. The versatility of the flexible walled test section is emphasized by reference to the simulation of alternative flows including cascade, steady pitching in an infinite flowfield, and ground effect. Finally, sources of error in streamlining are identified, with methods for their alleviation.

    The seven French agencies concerned by ocean research are developing together a strong capability in operational oceanography based on a triad including satellite altimetry (JASON), numerical modelling with assimilation (MERCATOR), and in situ data (CORIOLIS). The CORIOLIS project aims to build a pre-operational structure to collect, valid and distribute ocean data (temperature/salinity profiles and current speeds) to the scientific community and modellers. CORIOLIS aims at four goals : (1) To build up a data management centre, part of the ARGO network for the GODAE experiment, able to provide quality-controlled data in real time and delay modes. (2) To contribute to ARGO floats deployment mainly in the Atlantic with about 250 floats during the 2001-2004 period. (3) To develop and improve profiling ARGO floats. PROVOR is a self-ballasted float, able to drift at a user-defined parking depth and then to dive to 2000m before profiling up to the surface where data are transmitted using the Argos system. More than 100 cycles can be performed during its 3-year lifetime. (4) To integrate into CORIOLIS all other data presently collected at sea by French agencies from surface drifting buoys, PIRATA anchored buoys, oceanographic research vessels (XBT, thermosalinograph and ADCP transmitted on a daily basis). CORIOLIS data centre, already one of the two global data centres for ARGO, and aims to be an important partner in projects within GMES et 6th PRCD calls. In 2004, recommendations will be done to transform the CORIOLIS activity into a permanent, routinely contribution to ocean measurement, in accordance with international plans which will follow the ARGO/GODAE experiment.

    We are interested in the relationship between human vision and the environment in which it operates. To this end, the University of Southampton (UK) and York University (Canada) have collaborated to build the Southampton-York Natural Scenes (SYNS) public dataset. To represent the diverse environments that humans experience, we sampled scenes from 19 outdoor and 6 indoor scene categories across Hampshire, UK. Outdoor categories, identified by the UK Land Use dataset, include cropland, coastal dunes, woodlands, industrial estates, wetlands, residential areas, farms and orchards. Indoor categories include residential, theatres, cafes and offices. Each scene is represented by three types of co-registered data: (i) Ground truth 3D structure: 360° x 135° depth maps from a laser rangefinder (LiDAR), (ii) High dynamic range images (360° x 180°) captured by a SpheroCam and (iii) 18 Stereo image pairs (35° x 24°), tiling a 360° horizontal panorama, captured by a custom-built high-resolution stereo rig, with camera separation matched to average human interpupillary distance. LiDAR data were analysed to determine the distribution of surface attitude over slant and tilt in natural scenes. Surface normals were computed for patches centred on each LiDAR point, with the optimal patch size determined by cross-validation. Overall, the joint distribution over slant and tilt is dominated by the ground plane. For elevations above the horizon, other regularities are also apparent, including elevated probability density at the cardinal tilt axes (vertical surfaces), and a peak at fronto-parallel, as predicted by the geometry of projection. We relate these natural scene statistics to human perception of surface attitude and find a general correspondence, with human tilt perception biased toward the ground plane and slant perception biased toward fronto-parallel. These results suggest that human perception of surface attitude is governed in part by the ecological statistics of our visual environment. Meeting abstract presented at VSS 2015. PMID:26326414

  4. Oceanography: the present and future

    SciTech Connect

    Brewer, P.G.

    1982-01-01

    This volume is the proceedings of a symposium held September 29 to October 2, 1980 at Woods Hole, Massachusetts, commemorating the 50th anniversary of the founding of the Woods Hole Oceanographic Institution. The book is the companion volume to ''Oceanography: the Past'' also published by Springer-Verlag. The papers are organized not by conventional disciplinary topics but by the ''scale'' of the oceanographic process: Part I, Small and Local Scale Oceanography; Part II, Regional Scale Oceanography; Part III, Global Scale Oceanography; and Part IV, The Human Scale. The articles presented, however, do not summarize such projects but give recognizable disciplinary summaries and predictions in line with the subtitle of the book. In general, the articles are classed by this scale concept, although ''Shoreline Research'' by Pilkey and ''The Oceans Nearby'' by Murphy are better placed in the section The Human Scale and Bolin's ''Changing Global Biogeochemistry'' switched from The Human Scale to Global Scale as indicated by the title. This volume should be of value to marine geologists and geochemists, sedimentologists, and public-interest (environmental) geologists interested in oceanographic processes.

  5. Key Concepts in Microbial Oceanography

    2008-12-01

    The Center for Microbial Oceanography: Research and Education (C-MORE) is a multi-institution Science and Technology Center, established by the National Science Foundation in 2006. C-MORE's research mission is to facilitate a more comprehensive understanding of the diverse assemblages of microorganisms in the sea, ranging from the genetic basis of marine microbial biogeochemistry including the metabolic regulation and environmental controls of gene expression, to the processes that underpin the fluxes of carbon, related bioelements, and energy in the marine environment. The C-MORE education and outreach program is focused on increasing scientific literacy in microbial oceanography among students, educators, and the general public. A first step toward this goal is defining the key concepts that constitute microbial oceanography. After lengthy discussions with scientists and educators, both within and outside C-MORE, we have arrived at six key concepts: 1) Marine microbes are very small and have been around for a long time; 2) Life on Earth could not exist without microbes; 3) Most marine microbes are beneficial; 4) Microbes are everywhere: they are extremely abundant and diverse; 5) Microbes significantly impact our global climate; and 6) There are new discoveries every day in the field of microbial oceanography. A C-MORE-produced brochure on these six key concepts will be distributed at the meeting. Advanced copies may be requested by email or downloaded from the C-MORE web site(http://cmore.soest.hawaii.edu/downloads/MO_key_concepts_hi-res.pdf). This brochure also includes information on career pathways in microbial oceanography, with the aim of broadening participation in the field. C-MORE is eager to work in partnership to incorporate these key concepts into other science literacy publications, particularly those involving ocean and climate literacy. We thank the following contributors and reviewers: P Chisholm, A Dolberry, and A Thompson (MIT); N Lawrence (Santa Cruz Boardwalk); R Foster, S Mansergh and P Moisander (UC Santa Cruz); A Culley, K Doggett, J Edmonds, A Eiler, A Fong, D Hayakawa, D Karl, P Kemp, B Li, N Puniwai, B Wai, and S Wilson (U Hawaii); J Becker and M Nieto-Cid (WHOI); M McCaffrey (CIRES).

    United States progress in equatorial oceanography is reviewed, focusing on the low frequency response of upper equatorial oceans to forcing by the wind. Variations of thermocline depth, midocean currents, and boundary currents are discussed. The factors which determine sea surface temperature (SST) variability in equatorial oceans are reviewed, and the status of understanding of the most spectacular manifestation of SST variability, the El Nino-Southern Oscillation phenomenon, is discussed. The problem of observing surface winds, regarded as a fundamental factor limiting understanding of the equatorial oceans, is addressed. Finally, an attempt is made to identify those current trends which are expected to bear fruit in the near and distant future.

  13. Chemical Oceanography and the Marine Carbon Cycle

    NASA Astrophysics Data System (ADS)

    Emerson, Steven; Hedges, John

    The principles of chemical oceanography provide insight into the processes regulating the marine carbon cycle. The text offers a background in chemical oceanography and a description of how chemical elements in seawater and ocean sediments are used as tracers of physical, biological, chemical and geological processes in the ocean. The first seven chapters present basic topics of thermodynamics, isotope systematics and carbonate chemistry, and explain the influence of life on ocean chemistry and how it has evolved in the recent (glacial-interglacial) past. This is followed by topics essential to understanding the carbon cycle, including organic geochemistry, air-sea gas exchange, diffusion and reaction kinetics, the marine and atmosphere carbon cycle and diagenesis in marine sediments. Figures are available to download from www.cambridge.org/9780521833134. Ideal as a textbook for upper-level undergraduates and graduates in oceanography, environmental chemistry, geochemistry and earth science and a valuable reference for researchers in oceanography.

  14. The Oceans and the Teaching of Oceanography

    NASA Astrophysics Data System (ADS)

    Stewart, R. H.

    2002-12-01

    Sverdrup, Johnson and Fleming, the authors of \\textit{The Oceans}, were both ahead of their time, and behind their time. \\textit{The Oceans} built on earlier texts, such as Kummel's \\textit{Handbuch der Ozeanographie} (1907), that summarized our knowledge of the oceans. It differed principally in its depth and breadth, showing the need for specialized courses of study in biological, chemical, geological, and physical oceanography. Thus, the curriculum at the Scripps Institution of Oceanography was built on this foundation. As a result, no other comparable field of earth science was as well integrated as oceanography. For example, agriculture, which depends in some fundamental ways on weather, climate, and climate change did not include meteorology within its bounds, although it was nearly as broad as oceanography, including the study of soils, chemistry, and biology. The strengths of The Oceans were also its weakness. By emphasizing the strengths of the separate sub-disciplines of biological, chemical, geological, and physical oceanography the book drew oceanography away from problem-based studies such as those carried out by Bigelow in the Gulf of Maine. Case studies were not part of the basic curriculum. Thus, in 1964, 15 years after the start of the California Cooperative Fisheries Investigation, the most wide-ranging oceanographic study ever attempted, Scripps did not offer a course on the California fisheries. In contrast, other messy sciences, such as medicine, were often based on case studies. Now, at the start of the 21st century, the circle is nearly complete. Sub-disciplines such as physical oceanography are so broad they cannot be spanned in a single course. And students don't want to learn about important problems until late in their graduate career. To meet their interests, we have begun to offer courses in such topics as global warming or fisheries, bringing in ideas from biological, chemical, and physical oceanography only as needed.

    Pantoja, Silvio; Luis Iriarte, José; Daneri, Giovanni

    2011-03-01

    Chilean Patagonia is one of the most extended fjord regions in the world that covers nearly 240,000 km 2 with an extremely complex coastline and topography in one of the least densely populated areas of the country (1-8 inhabitants every 10 km 2). In recent years, the area has been undergoing somewhat intense pressure since several commercial projects in hydroelectricity, tourism, and commercial salmon and mytilid cultures have been developed, or are in progress. Concomitantly, several large research programs have been devised to study the physical, chemical, and biological environment of Patagonia, such as the CIMAR FIORDO, and recently COPAS Sur-Austral based at Universidad de Concepcion, that attempts to close the bridge between oceanographic knowledge and its use by society. In this introductory article we summarize the collection of papers comprising this Special Issue of Continental Shelf Research. These papers deal with aspects of regional oceanography and geology, inorganic and organic geochemistry, ecology of pelagic and benthic organisms, and past changes in productivity.

    Gregson, Sarah

    2012-01-01

    One of the principal narratives woven around the 1912 sinking of the Titanic is that the tragedy united people around the world in a shared sense of horror and grief. This study examines the administration of the relief fund collected for victims and questions the established image of social unity and collective suffering. The records of the Southampton Titanic Relief Fund reveal welfare processes imbued with class and gender prejudices that consigned many of the relatives of victims to poverty-stricken lives, despite the massive fund collected in their names.

  2. From marine ecology to biological oceanography

    NASA Astrophysics Data System (ADS)

    Mills, Eric L.

    1995-03-01

    Looking back from the 1990s it seems natural to view the work done in the Biologische Anstalt Helgoland by Friedrich Heincke and his colleagues, beginning in 1892, as marine ecology or marine biology, and that done in Kiel, under Victor Hensen and Karl Brandt, as biological oceanography. But historical analysis shows this view to be untenable. Biological oceanography, as a research category and a profession, does not appear until at least the 1950's. In the German tradition of marine research, “Ozeanographie”, originating in 19th century physical geography, did not include the biological sciences. The categories “Meereskunde” and “Meeresforschung” covered all aspects of marine research in Germany from the 1890's to the present day. “Meeresbiologie” like that of Brandt, Heincke, and other German marine scientists, fitted comfortably into these. But in North America no such satisfactory professional or definitional structure existed before the late 1950's. G. A. Riley, one of the first biological oceanographers, fought against descriptive, nonquantitative American ecology. In 1951 he described biological oceanography as the “ecology of marine populations”, linking it with quantitative population ecology in the U.S.A. By the end of the 1960's the U.S. National Science Foundation had recognized biological oceanography as a research area supported separately from marine biology. There was no need for the category “biological oceanography” in German marine science because its subject matter lay under the umbrella of “Meereskunde” or “Meeresforschung”. But in North America, biological oceanography — a fundamental fusion of physics and chemistry with marine biology — was created to give this marine science a status higher than that of the conceptually overloaded ecological sciences. The sociologists Durkheim and Mauss claimed in 1903 that, “the classification of things reproduces the classification of men”; similarly, in science, the classification of professions reproduces the status that their practitioners hope to achieve.

    Parker, David H.

    1987-01-01

    An all digital five channel position detection system is to be installed in the Southampton University Magnetic Suspension and Balance System (SUMSBS). The system is intended to monitor a much larger range of model pitch attitudes than has been possible hitherto, up to a maximum of a 90 degree angle of attack. It is based on the use of self-scanning photodiode arrays and illuminating laser light beams, together with purpose built processing electronics. The principles behind the design of the system are discussed, together with the results of testing one channel of the system which was used to control the axial position of a magnetically suspended model in SUMSBS. The removal of optically coupled heave position information from the axial position sensing channel is described.

  6. Remote sensing for oceanography: Past, present, future

    NASA Technical Reports Server (NTRS)

    Mcgoldrick, L. F.

    1984-01-01

    Oceanic dynamics was traditionally investigated by sampling from instruments in situ, yielding quantitative measurements that are intermittent in both space and time; the ocean is undersampled. The need to obtain proper sampling of the averaged quantities treated in analytical and numerical models is at present the most significant limitation on advances in physical oceanography. Within the past decade, many electromagnetic techniques for the study of the Earth and planets were applied to the study of the ocean. Now satellites promise nearly total coverage of the world's oceans using only a few days to a few weeks of observations. Both a review of the early and present techniques applied to satellite oceanography and a description of some future systems to be launched into orbit during the remainder of this century are presented. Both scientific and technologic capabilities are discussed.

    1992-01-01

    The field of oceanography has existed as a major scientific discipline in the United States since World War 2, largely funded by the federal government. In this report, the Ocean Studies Board documents the state of the field of oceanography and assesses the health of the partnership between the federal government and the academic oceanography community. The objectives are to document and discuss important trends in the human, physical, and fiscal resources available to oceanographers, especially academic oceanographers, over the last decade; to present the Ocean Studies Board's best assessment of scientific opportunities in physical oceanography, marine geochemistry, marine geology and geophysics, biological oceanography, and coastal oceanography during the upcoming decade; and to provide a blueprint for more productive partnerships between academic oceanographers and federal agencies.

    1979-01-01

    A single-frequency multibeam synthetic aperture radar concept for large swath imaging desired for global oceanography is evaluated. Each beam iilluminates a separate range and azimuth interval, and images for different beams may be separated on the basis of the Doppler spectrum of the beams or their spatial azimuth separation in the image plane of the radar processor. The azimuth resolution of the radar system is selected so that the Doppler spectrum of each beam does not interfere with the Doppler foldover due to the finite pulse repetition frequency of the radar system.

    2013-07-01

    Due to biotechnological advances and the ever-decreasing cost of sequencing in recent years, there has been a major shift in microbial oceanography to include data on the sequences of genes, gene transcripts, and proteins from environmentally relevant organisms and naturally occurring mixed communities in studies of marine ecosystems. This research area is collectively called "-omics," referring to genomics, transcriptomics, and proteomics of individual organisms and metagenomics, metatranscriptomics, and metaproteomics of mixed communities. These data provide information about how organisms interact with their environment.

    2015-04-01

    Operational oceanography predictions are now starting to include coupled wind, wave and current fields for open ocean and shelf domains. However the same product for coastal scales, including a) the non-linearity of coastal processes, b) the effect of continental rain driven discharge and c) the interaction with coastal structures are still in an early stage of development, both for the physical and numerical aspects. In this paper we shall explore a coupled wind-wave-current model based on the COWAST system but including also the continental discharge and the effect of coastal structures, in particular shore parallel detached breakwaters. We shall apply such a pre-operational code to a test case near Barcelona, where the concept of transient coastal defences is being considered. The available in-situ and remote observations should also allow a robust calibration. The operational oceanography simulations will be used to support the activation of these transient coastal defences and therefore illustrate the challenges required by coastal scales under rapid storm development such as is commonly found in the Western Mediterranean. The benefits of applying a robust and high resolution coupled hydro-dynamic system will become apparent from the stand point of transient coastal defence deployment and risk mitigation in heavily populated coastal areas.

  18. From satellite altimetry to Argo and operational oceanography: three revolutions in oceanography

    NASA Astrophysics Data System (ADS)

    Le Traon, P. Y.

    2013-10-01

    The launch of the French/US mission Topex/Poseidon (T/P) (CNES/NASA) in August 1992 was the start of a revolution in oceanography. For the first time, a very precise altimeter system optimized for large-scale sea level and ocean circulation observations was flying. T/P alone could not observe the mesoscale circulation. In the 1990s, the ESA satellites ERS-1/2 were flying simultaneously with T/P. Together with my CLS colleagues, we demonstrated that we could use T/P as a reference mission for ERS-1/2 and bring the ERS-1/2 data to an accuracy level comparable to T/P. Near-real-time high-resolution global sea level anomaly maps were then derived. These maps have been operationally produced as part of the SSALTO/DUACS system for the last 15 yr. They are now widely used by the oceanographic community and have contributed to a much better understanding and recognition of the role and importance of mesoscale dynamics. Altimetry needs to be complemented with global in situ observations. At the end of the 90s, a major international initiative was launched to develop Argo, the global array of profiling floats. This has been an outstanding success. Argo floats now provide the most important in situ observations to monitor and understand the role of the ocean on the earth climate and for operational oceanography. This is a second revolution in oceanography. The unique capability of satellite altimetry to observe the global ocean in near-real-time at high resolution and the development of Argo were essential for the development of global operational oceanography, the third revolution in oceanography. The Global Ocean Data Assimilation Experiment (GODAE) was instrumental in the development of the required capabilities. This paper provides an historical perspective on the development of these three revolutions in oceanography which are very much interlinked. This is not an exhaustive review and I will mainly focus on the contributions we made together with many colleagues and friends.

  19. Preliminary study of the Southampton Hand Assessment Procedure for Children and its reliability

    PubMed Central

    2014-01-01

    Background The Southampton Hand Assessment Procedure (SHAP) is currently used in the adult population for evaluating the functionality of impaired or prosthetic hands. The SHAP cannot be used for children because of the relatively larger size of the objects used to perform SHAP tasks and unknown clinimetric properties. The aims of this study were to adapt the SHAP for use in children (SHAP-C), to determine norm values for the SHAP-C, and to analyze the reliability of the SHAP-C. Methods The SHAP-C was adapted based on the SHAP protocol. Some objects were downsized, and the timing of tasks was performed by the rater instead of the participant. Intra- and inter-rater reliability were assessed in 24 children (5 [0.54] y/o) with unimpaired hands. The repeatability coefficients (RCs) were calculated. An RC ≤ 75% of the mean SHAP-C task values was considered good reliability. Results Participants were able to perform all SHAP-C tasks. The means of the SHAP-C tasks ranged from 0.75 to 1.21 seconds for abstract objects and from 0.64-19.13 seconds for activities of daily living. The RCs of a single assessor did not exceed 75% in 17/26 SHAP-C tasks, displaying a relatively good intra-rater reliability, whereas the RCs for the inter-rater reliability exceeded 75% in 22/26 SHAP-C tasks, thus displaying poor reliability. Conclusion In this first study that adjusted the SHAP for pediatric use, we found that all SHAP-C objects and tasks could be performed by children. The intra-rater reliability was better than the inter-rater reliability. Although the SHAP-C appears to be a promising instrument, the protocol requires further modifications to provide reliable measurements in children. PMID:24916917

  20. Relation of FTO gene variants to fetal growth trajectories: Findings from the Southampton Women's survey

    Introduction Placental function is an important determinant of fetal growth, and fetal growth influences obesity risk in childhood and adult life. Here we investigated how FTO and MC4R gene variants linked with obesity relate to patterns of fetal growth and to placental FTO expression. Methods Southampton Women's Survey children (n = 1990) with measurements of fetal growth from 11 to 34 weeks gestation were genotyped for common gene variants in FTO (rs9939609, rs1421085) and MC4R (rs17782313). Linear mixed-effect models were used to analyse relations of gene variants with fetal growth. Results Fetuses with the rs9939609 A:A FTO genotype had faster biparietal diameter and head circumference growth velocities between 11 and 34 weeks gestation (by 0.012 (95% CI 0.005 to 0.019) and 0.008 (0.002–0.015) standard deviations per week, respectively) compared to fetuses with the T:T FTO genotype; abdominal circumference growth velocity did not differ between genotypes. FTO genotype was not associated with placental FTO expression, but higher placental FTO expression was independently associated with larger fetal size and higher placental ASCT2, EAAT2 and y + LAT2 amino acid transporter expression. Findings were similar for FTO rs1421085, and the MC4R gene variant was associated with the fetal growth velocity of head circumference. Discussion FTO gene variants are known to associate with obesity but this is the first time that the risk alleles and placental FTO expression have been linked with fetal growth trajectories. The lack of an association between FTO genotype and placental FTO expression adds to emerging evidence of complex biology underlying the association between FTO genotype and obesity. PMID:26907388

  1. Attenders at young people's clinics in Southampton: variations in contraceptive use.

    1998-10-01

    This paper presents findings from a survey of 424 people attending nine young people's clinics within the Southampton Community Health NHS Trust. In addition to recording some descriptive background data on the people attending the clinics, one major aim of the study was to investigate whether talking to the sexual partner about contraception before their first intercourse together and delaying this first intercourse influenced contraceptive use. Overall, 40 per cent of people attending the clinics were aged 16 or under, although there was some variation between clinics in the age groups attracted. Most clients were female (88 per cent), had ever had sexual intercourse (92 per cent), reported four or more lifetime partners (42 per cent) but only one partner within the last six months (73 per cent) and were currently in a relationship (75 per cent). Potential for contraception and sexually transmitted infection was widespread; 46 per cent (of non-virgins) had had intercourse without contraception at least 'a few times' and 18 per cent used condoms 'rarely' or 'never'. In terms of first intercourse with current/most recent partner, 17 per cent had not used any contraception and 32 per cent had failed to use condoms. The most important findings from this study were that use of contraception (and condoms in particular) on the occasion of first intercourse with the current or most recent partner was significantly associated with the following; if partners had talked to each other about contraception before having intercourse together for the first time (p<0.001), and also if this first intercourse was delayed beyond four weeks as opposed to over a few days of first 'going-out' together (p<0.001). Suggestions for further in-depth research are made. PMID:9855715

    Seismic oceanography (SO) uses multichannel seismic techniques to visualize the ocean's fine structure, yielding a tool for investigating ocean mixing processes and their links with mesoscale features such as eddies, fronts, and currents. Ten years after the seminal paper initiating the SO field (W. S. Holbrook, P. Páramo, S. Pearse, and R. W. Schmitt, Thermohaline fine structure in an oceanographic front from seismic reflection profiling, Science, 301, 821-824, 2003), a special session and mini-workshop were convened at the International Congress on Acoustics in Montreal on 2-7 June 2013. At the workshop, participants discussed the successes of SO, the challenges it faces as an observational tool, and ways to move the field forward.

  5. Arsenic Speciation and Seasonal Changes in Nutrient Availability and Micro-plankton Abundance in Southampton Water, U.K.

    Howard, A. G.; Comber, S. D. W.; Kifle, D.; Antai, E. E.; Purdie, D. A.

    1995-04-01

    The links between dissolved arsenic speciation, biological activity and the availabilities of the nitrogen and phosphorus plant nutrients have been investigated in a seasonal survey of Southampton Water (U.K.). Southampton Water (Hampshire, southern England) is an approximately 10 km long, and 2 km wide north-westerly extension of the Solent, receiving water from the rivers Test and Itchen. It is a partially mixed estuary bordered by broad intertidal mudflats with shingle and sand on the eastern side, and a salt marsh to the west. Two sites were chosen: NW Netley Buoy is in a sheltered high-salinity estuarine environment whilst Calshot Buoy lies just outside Southampton Water and in a more exposed location of less-variable salinity. The first evidence of arsenic(III) production at both sites occurred in the second half of April, during the decay of a major Skeletonema costatumdiatom bloom. Arsenic(III) levels rose as Skeletonemawas replaced by a numerically smaller but more chlorophyll-rich bloom of another diatom, Rhizosolenia delicatula. Rhizosoleniais therefore implicated as a possible source of arsenic(III). Methylated arsenic was absent whilst the water temperature was low and during the initial Skeletonemabloom, but a week later, during the growth phase of the succeeding bloom of the diatom R. delicatula, they became detectable. Methylated arsenic levels gradually increased through the spring to a broad maximum covering the mid-summer, when Mesodinium rubrum, Scrippsiella trochoideaand associated microflagellates also peaked. No subsequent single organism could be linked to the release of methylated arsenic into Southampton Water; organoarsenicals having been observed in the presence of flagellates, diatoms and ciliates. A large bacterial maximum was observed following blooms of S. trochoideaand M. rubrumbut laboratory culture experiments of natural bacteria from Netley failed to produce significant changes in the concentration of any arsenic species. Phosphate depletion did not appear to be a prerequisite for arsenate assimilation. From the summer peak methylated arsenic levels then gradually diminished to undetectable levels in the winter months. Monomethylarsenic, present at concentrations approximately 50% those of dimethylarsenic, persisted longer through the summer. The arsenic species which can be measured using the hydride procedure may therefore represent intermediates in the decomposition of the bioarsenicals, such as arsenosugars, which are released, either actively as excretion/secretion products or passively as part of the decay process. Currently unidentified precursors of hydride-reducible arsenic species (' hidden ' arsenic) may explain the poor link between planktonic activity and the levels of measurable arsenic species in the water column.

  6. From satellite altimetry to operational oceanography and Argo: three revolutions in oceanography (Fridtjof Nansen Medal Lecture)

    NASA Astrophysics Data System (ADS)

    Le Traon, P. Y.

    2012-04-01

    The launch of the US/French mission Topex/Poseidon (T/P) (CNES/NASA) in August 1992 was the start of a revolution in oceanography. For the first time, a very precise altimeter system optimized for large scale sea level and ocean circulation observations was flying. Topex/Poseidon revolutionized our vision and understanding of the ocean. It provided new views of the large scale seasonal and interannual sea level and ocean circulation variations. T/P alone could not observe the mesoscale circulation. In the 1990s, the ESA satellites ERS-1/2 were flying simultaneously with T/P. The ERS-1/2 orbit was well adapted for mesoscale circulation sampling but the orbit determination and altimeter performance were much less precise than for T/P. We demonstrated that we could use T/P as a reference mission for ERS-1/2 and bring the ERS-1/2 data to an accuracy level comparable to T/P. This was an essential first step for the merging of T/P and ERS-1/2. The second step required the development of a global optimal interpolation method. Near real time high resolution global sea level anomaly maps were then derived. These maps have been operationally produced as part of the SSALTO/DUACS system for the last 15 years. They are now widely used by the oceanographic community and have contributed to a much better understanding and recognition of the role and importance of mesoscale dynamics. The unique capability of satellite altimetry to observe the global ocean in near real time at high resolution was essential to the development of global ocean forecasting, a second revolution in oceanography. The Global Ocean Data Assimilation Experiment (GODAE) (1998-2008) was phased with the T/P and ERS-1/2 successors (Jason-1 and ENVISAT) and was instrumental in the development of global operational oceanography capabilities. Europe played a leading role in GODAE. In 1998, the global in-situ observing system was inadequate for the global scope of GODAE. This led to the development of Argo, an initial joint venture between CLIVAR and GODAE. Argo has been an outstanding success. The 3000 Argo profiling floats now provide the most important global in-situ observations to monitor and understand the role of the ocean on the earth climate. This is a third revolution in oceanography. I was lucky enough to be involved with many colleagues and friends in these three revolutions or breakthroughs in oceanography. The presentation will provide some historical background on the development of the SSALTO/DUACS merged altimeter products and an overview of their utility and use for ocean research and operational oceanography. I will thengo throughthe development of operational oceanography and Argo over the past 15 years focussing on European contributions, in particular, in the framework of the GMES Marine Service, EuroGOOSand the Euro-Argo research infrastructure. Perspectives and new challenges for the integrated global ocean observing system will be finally discussed.

  9. Titan - a New Laboratory for Oceanography

    NASA Astrophysics Data System (ADS)

    Lorenz, R. D.

    2001-12-01

    Saturn's giant moon Titan has a thick (1.5 bar) nitrogen atmosphere, and quite probably large expanses of liquid hydrocarbons on its surface. The physical processes in these lakes and seas will open new vistas on oceanography and limnology. Although the Voyager-era paradigm of a deep, global ocean is ruled out by radar and infrared data showing that at least part of Titan's surface is icy, the photochemical arguments that originally led to the proposal of hydrocarbon oceans still apply. Even if the methane in the atmosphere is being resupplied by delivery from the interior, the ethane produced by photolysis would still accumulate to form large deposits on the surface. The near-infrared maps of Titan's surface from the Hubble Space Telescope and groundbased adaptive optics consistently show a number of dark (in fact, pitch-black!) regions that are strong candidates for hydrocarbon seas. These could be up to some 500km in extent. Titan promises to be a new laboratory for oceanography. Like in meteorology, many ocean processes are better parameterized than they are understood, and thus the different physical circumstances on Titan may shed new light on them. Titan has a lower gravity and its ocean fluids are of lower density, perhaps of lower viscosity (depending on solutes and suspended material) and probably rather more likely to cavitate. The ratio of atmospheric density to ocean density is much larger on Titan than on Earth, suggesting that liquid motions will be well-coupled to surface winds (although the distance from the sun is such that the energy in such winds is likely to be low.) Titan is also subject to strong tidal forces (the equilibrium tide due to Saturn's gravity is some 400x larger than that of the moon on Earth.) Although the 100m tidal bulge stays almost fixed because Titan rotates synchronously, the eccentricity of Titan's orbit leads to significant libration and variation in the tidal strength. The 500km seas allowed by the IR data may yet have a 2m tidal amplitude. The long period of tidal excitation, however, means that tidal resonances are unlikely to occur. The NASA-ESA Cassini/Huygens mission will arrive in late 2004, and deliver the parachute-borne Huygens probe to Titan's surface in early 2005, taking images during its descent. The Cassini orbiter during its 4 year tour will fly by Titan some 45 times, taking SAR and altimeter data with a multimode radar, and observing the surface with optical and near-IR sensors. Future missions to Titan are already being contemplated, and might involve such platforms as helicopters or blimps.

  10. Mapping turbidity currents using seismic oceanography

    Using a combination of seismic oceanographic and physical oceanographic data acquired across the Faroe-Shetland Channel we present evidence of a turbidity current that transports suspended sediment along the western boundary of the Channel. We focus on reflections observed on seismic data close to the sea-bed on the Faroese side of the Channel below 900m. Forward modelling based on independent physical oceanographic data show that thermohaline structure does not explain these near sea-bed reflections but they are consistent with optical backscatter data, dry matter concentrations from water samples and from seabed sediment traps. Hence we conclude that an impedance contrast in water column caused by turbidity currents is strong enough to be seen in seismic sections and this provides a new way to visualise this type of current and its lateral structure. By inverting the seismic data we estimate a sediment concentration in the turbidity current, present at the time of the survey, of 45 ± 25 mg l-1. We believe this is the first direct observation of a turbidity current using Seismic Oceanography.

  13. Graduate students in oceanography: Recruitment, success, and career prospects

    NASA Astrophysics Data System (ADS)

    Nowell, Arthur R. M.; Hollister, Charles D.

    Graduate education, student quality, stipend support, and subsequent employment form a triad of concern to many oceanographers. While the number of graduate degree programs in oceanography in the U.S. exceeds 50, remarkably few data are available on numbers of student applications, student survival rates, the quality of the applicants and accepted students, and their subsequent employment.Consequently, most discussions within an institution are based on data from a single school, while most statements made to federal government program managers by scientists are based on personal perceptions and feelings. With the emerging global initiatives, which are very labor intensive, it appears appropriate to ask, “Is there an impending crisis in graduate education in oceanography?” Widespread concern about availability of new talent, the quality of incoming students, and the overall national crisis in science and engineering student recruitment has led many scientists to state that oceanography has widespread problems in terms of student numbers and, more importantly, quality. Often, when a scientist does not find a student in the spring application rites, the scientist declares there is a national shortage of well-qualified students. Moreover, in certain subdisciplines of the field (e.g., physical oceanography) the crisis is perceived as severe and immediate, though as we shall see, physical oceanography is in an improving mode and is also experiencing an interesting increase in the numbers of well-qualified women applicants.

    At the close of World War II Scripps was the only program in the United States offering formal graduate education and degrees in oceanography. Much early course work was based on The Oceans. All students were required to take introductory courses in biological, chemical, geological and physical oceanography, and one's first oral exams were largely based on those four courses. Many of the founding directors of the growing number of oceanography programs established after World War II in the United States were Scripps graduates. These included directors of programs at the University of Washington, Oregon State, Texas A and M, and the University of Rhode Island. All adopted the Scripps model and The Oceans philosophy in developing their educational programs.

    Application of optimal data assimilation methods in oceanography is, if anything, more important than it is in numerical weather prediction, due to the sparsity of data. Here, a general framework is presented and practical examples taken from the author`s work are described, with the purpose of conveying to the reader some idea of the state of the art of data assimilation in oceanography. While no attempt is made to be exhaustive, references to other lines of research are included. Major challenges to the community include design of statistical error models and handling of strong nonlinearity.

    SOCIB, the Balearic Islands Coastal Ocean Observing and Forecasting System (http://www.socib.es), is a Marine Research Infrastructure, a multiplatform distributed and integrated system, a facility of facilities that extends from the nearshore to the open sea and provides free, open and quality control data. SOCIB is a facility o facilities and has three major infrastructure components: (1) a distributed multiplatform observing system, (2) a numerical forecasting system, and (3) a data management and visualization system. We present the spatial data infrastructure and applications developed at SOCIB. One of the major goals of the SOCIB Data Centre is to provide users with a system to locate and download the data of interest (near real-time and delayed mode) and to visualize and manage the information. Following SOCIB principles, data need to be (1) discoverable and accessible, (2) freely available, and (3) interoperable and standardized. In consequence, SOCIB Data Centre Facility is implementing a general data management system to guarantee international standards, quality assurance and interoperability. The combination of different sources and types of information requires appropriate methods to ingest, catalogue, display, and distribute this information. SOCIB Data Centre is responsible for directing the different stages of data management, ranging from data acquisition to its distribution and visualization through web applications. The system implemented relies on open source solutions. In other words, the data life cycle relies in the following stages: • Acquisition: The data managed by SOCIB mostly come from its own observation platforms, numerical models or information generated from the activities in the SIAS Division. • Processing: Applications developed at SOCIB to deal with all collected platform data performing data calibration, derivation, quality control and standardization. • Archival: Storage in netCDF and spatial databases. • Distribution: Data web services using Thredds, Geoserver and RESTful own services. • Catalogue: Metadata is provided through the ncISO plugin in Thredds and Geonetwork. • Visualization: web and mobile applications to present SOCIB data to different user profiles. SOCIB data services and applications have been developed to provide response to science and society needs (eg. European initiatives such as Emodnet or Copernicus), by targeting different user profiles (eg. researchers, technicians, policy and decision makers, educators, students, and society in general). For example, SOCIB has developed applications to: 1) allow researchers and technicians to access oceanographic information; 2) provide decision support for oil spills response; 3) disseminate information about the coastal state for tourists and recreational users; 4) present coastal research in educational programs; and 5) offer easy and fast access to marine information through mobile devices. In conclusion, the organizational and conceptual structure of SOCIB's Data Centre and the components developed provide an example of marine information systems within the framework of new ocean observatories and/or marine research infrastructures.

    An Earth Summit approach in UCSB's undergraduate physical oceanography course has raised student interest level while it also supports the course goals of increased learner awareness of the process of science, and critical analysis of scientific claims. At the beginning of the quarter, each group of students chooses a country to represent in the Earth Summit. During the course of the quarter, these groups relate each of the class themes to their chosen country. Themes include 1) ocean basins and plate tectonics, 2) atmospheres, oceans and climate, and 3) fisheries. Students acquire and utilize Earth data to support their positions. Earth data sources include the "Our Dynamic Planet" CDROM (http://oceanography.geol.ucsb.edu/ODP_Advert/odp_onepage.htm), NOAA's ocean and climate database (http://ferret.wrc.noaa.gov/las/), WorldWatcher CD (http://www.worldwatcher.northwestern.edu/) and JPL's Seawinds web site (http://haifung.jpl.nasa.gov/index.html). During the atmospheres, oceans and climate theme, students choose from 12 mini-studies that use various kinds of on-line Earth data related to important global or regional phenomena relevant to the course. The Earth datasets that the students access for their analysis include: winds; atmospheric pressure; ocean chemistry; sea surface temperature; solar radiation; precipitation, etc. The first group of 6 mini-studies focus on atmosphere and ocean, and are: 1) global winds and surface currents, 2) atmosphere and ocean interactions, 3) stratospheric ozone depletion, 4) El Nino, 5) Indian monsoon, and 6) deep ocean circulation. The second group focus on the Earth's heat budget and climate and are: 1) influence of man's activities on the climate, 2) the greenhouse effect, 3) seasonal variation and the Earth's heat budget, 4) global warming, 5) paleoclimate, and 6) volcanoes and climate. The students use what they have learned in these mini-studies to address atmospheric and climatic issues pertinent to their specific Earth Summit countries. For example, students representing the country of Chile might model their investigations after a)winds and surface currents, b)atmosphere and ocean interactions, c) stratospheric ozone depletion, d)El Nino; and/or e)volcanoes and climate. Please join the "Oceanography" interest group of DLESE to discuss, develop, and access oceanography related mini-studies that use earth data (http://oceanography.geol.ucsb.edu/dlese/wg_oceanog/Index.html). >http://oceanography.geol.ucsb.edu/AWP/Class_Info/GS-4/Labs/Labs Index.html

  4. Biological oceanography of the red oceanic system

    NASA Astrophysics Data System (ADS)

    Theil, Hjalmar; Weikert, Horst

    1. In 1977, 1979 and 1980-81, investigations were carried out which aimed at evaluating the potential risks from mining metalliferous muds precipating in the Atlantis II Deep of the central Red Sea. This environmental research was initiated by the Saudi Sudanese Red Sea Joint Commission in order to avoid any danger for the Red Sea ecosystem. The broad environmental research programme coherent studies in physical, chemical, biological, and geological oceanography as well as toxicological investigations in the oceanic and in reef zones. We summarise the results from our biological fiels studies in the open sea. 2. The biological investigations were concentrated on the area of the Atlantis II Deep. Benthos was sampled between 700-2000m. For comparison a few samples were also taken further north in the central Red Sea, and to east and west along the flanking deep terraces (500-1000m). Plankton studies covered the total water column above the Deep, and were extended along the axial through to north and south. 3. Benthos sampling was carried out using a heavy closing trawl, a large box grab (box size 50 × 50 cm), Van Veen grabs and traps; photographic surveys were made a phototrap and a photosled. Community respiration was measured with a ship-board method using grab subsamples. Nutrient concentrations, seston and phytoplankton standing stocks as well as in situ primary production were determined from hydrocast samples. Data on zooplankton and micronekton composition and standing stock were obtained from samples collected using different multiple opening-and-closing nets equipped with 100 μm, 300 μm, and 1000 μm mesh sizes. Daily and ontogenetical vertical migration patterns were studied by comparisons of data from midday and midnight tows. 4. Throughout the whole area the sediment is a pteropod ooze containing low contentrations of organic matter; measured organic carbon and nitrogen contents were 0.5 and 0.05% respectively, and chloroplastic pigment equivalents (chlorophyll and degradation products) were mostly at the lower limit of determination with up to 1.2 ng·cm -. Similarly the faunal components were rare. Meiofauna occured at abundances of up to 600 specimens·10 cm -2 (<0.3mg ash free dry weight · 10 cm -2), and macrofauna with up to 960 specimens · m -2. Photosled surveys showed low densities of megafauna of up to 20 specimens ·100m -2 (Thiel, 1979, 1981). The number of species is low compared with other regions, but some species seem to penetrate into greater depths in the Red Sea than in the Indian Ocean, possibly because of the high temperature of the Red Sea deep water. It reveals an interesting adaptation by these species to life in this low energy ecosystem (Thiel, 1979, 1980, in press; Klausewitz and Thiel, 1982). 5. Phytoplankton production was low in the euphotic zone overlying the Atlantis II Deep area and did not exceed 100 mg C · m -2 d -2 most of the year. Similarly, the levels of the standing stocks of seston, phytoplankton and zooplankton were typical of oligotrophic conditions. For all three categories, the average standing stocks were lowest in autum, but the maxima for each occured in different seasons. The seston stock was greatest in spring (March) amounting to 90 g dry weight · m -2 in the upper 75m higher by a factor of 2 than in autum. The phytoplankton stock was greatest in spring, and at the biggining of summer (June) when it reached about 17 mg chl a · m -2 in the euphotic zone, about 1.6 times the minimum autumn level. The zooplankton stock was greatest in winter (February) when it attained 15 g wet weight · m -2 or 51,000 individuals · m -2 in the total 1850m water colunm, values which were a factor of 3 and 1.6 higher respectively than in autum (Weikert, 1980a, 1981). The zooplankton stock which is poor in species exhibits a conspicuous planktocline below 100m, which roughly corresponds to the bottom of the euphotic zone. In winter, the planktocline shifts some tens of metres towards the sea surface. A secondary zooplankton maximum which overlaps with the deep scattering layer, is situated between 300-600m, and is confined to the oxygen minimum layer (Weikert, 1980a,b). Below about 1100m, the planktonic standing crop is extremely low, for example at about 1450m the abundance of the 300 μm net plankton was <0.1 mg wet weight · 100 m -3 with only 0.4 specimens · 100 m -3. The profiles of zooplankton abundance and biomass are paralled by the profile of diversity which is greatly reduced in the subsurface zooplankton communities. These findings were repeated both from different seasons and from other sites along the deep graben (Weikert, 1980a: Beckmann, 1984); all together they depict an extreme example of the peculiar bathymetric distribution of zooplankton typical of other partially land-locked seas (Weikert, 1982). No diel vertical migrations were observed below 1100m. All organic matter must be transported to greater depths and to the bottom in the form of sinking particles. However, the quantities of organic material which sink to such depths will be small, because decomposition rates can be expected much higher than normal because of the high uniform temperatures (21.6°C) of the deep water (Weikert, 1982). 6. Respiration measurements and the determinations of electron transport system activity were conducted on small, undisturbed sediment samples. The data can be evaluated by comparison with results obtained from the Arctic and the Atlantic Oceans employing exactly the same methods. In the Red Sea, respiration and ETS activity were found to be high but standing stocks and biomasses were low; the reverse was observed in the Arctic and the Atlantic. We believe that this difference in the ratio of respiration to biomass is determined by the great contrasts in the temperatures of the environments studied: Arctic -1.5°C, Atlantic 2°C, Red Sea 21.5°C. Independent of the species' adaptations to their environment this temperature influence will apply to all the living components of the ecosystem. Hence for Red Sea organisms maintenance costs are comparatively high, which greatly reduces their production potential. 7. Thus the oceanic ecosystem of the Red Sea can be summarised as follows: Primary production is low throughout most of the year and throughout most of the entire basin, and consequently so is secondary production (zooplankton). In subsurface waters, high maintenance costs reduces energy for investments in growth and reproduction. In addition degradation of organic matter is so fast in the upper layers that the standing stock in the intermediate layers is reduced and particle transport to greater depth in the central graben greatly restricted. The low abundance and biomass of the deep-sea plankton and benthos in the Red Sea is readily explained by the low availability of food and the high metabolic demands created by the unique high in situ temperature.

  8. Evaluating the potential of Southampton Carbon flux (SCARF) model to predict terrestrial gross primary productivity over Africa.

    The amount of carbon uptake by vegetation is an important component to understand the functioning of ecosystem processes and their response/feedback to climate. Recently a new diagnostic model called the Southampton Carbon flux (SCARF) model was develop to predict terrestrial gross primary productivity at regional to global scale using satellite data. The model based on the quantum yield of vegetation improves on the previous diagnostic model by (i) using the fraction of photosynthetic active radiation absorbed by the photosynthetic pigment (FAPAR _{ps}) and (ii) using direct quantum yield by classifying the vegetation into C3 or C4 classes. Initial results suggest a very good agreement with expected results for ecosystems where the growth is controlled by temperature (e.g. Northern higher latitude). In this paper we calibrated and validated the model for a range of vegetation types across Africa, in order to test the performance of vegetation over a water limiting ecosystem. The vapour pressure deficit term (VPD) was modified to quantify the water loss and in turn reduced carbon assimilation through Evapotranspiration. The performance of the model was evaluated with GPP measured at eight eddy covariance flux tower data across Africa. Overall, the modelled GPP values show good agreement with observed GPP at most sites (except tropical rainforest site) in terms of their seasonality and absolute values. Mean daily GPP across the investigated period varied significantly across sites depending on the vegetation types from a minimum of 0.64 gC m (2) day (-1) for the dry savannah grassland at Demokeya to a maximum of 7.83 gC m (2) day (-1) for tropical rain forest at Ankasa. The model results have modest to very strong positive agreement with observed GPP at most sites (r (2) values ranging from 0.58 for Kruger and 0.84 for Mongu). Generally, strong correlation is observed in woodlands and grasslands where vegetation follows a prescribed seasonal cycle as determined by canopy Chlorophyll content.

    Noroviruses are the predominant cause of human epidemic nonbacterial gastroenteritis. Viral replication requires a cysteine protease that cleaves a 200 kDa viral polyprotein into its constituent functional parts. Here, the crystallization of the recombinant protease from the Southampton norovirus is described. While the native crystals were found to diffract only to medium resolution (2.9 {angstrom}), cocrystals of an inhibitor complex diffracted X-rays to 1.7 {angstrom} resolution. The polypeptide inhibitor (Ac-EFQLQ-propenyl ethyl ester) possesses an amino-acid sequence designed to match the substrate specificity of the enzyme, but was synthesized with a reactive Michael acceptor group at the C-terminal end.

  10. Development of an Introductory Oceanography Concept Inventory Survey

    NASA Astrophysics Data System (ADS)

    Arthurs, L.; Marchitto, T.

    2008-12-01

    Concept inventories are one type of assessment that can be used to evaluate whether a student has an accurate and working knowledge of a specific set of concepts. Although such assessment tools have been developed in astronomy, biology, chemistry, engineering, fluid mechanics, geology, and physics, none has been available. Our development of an Introductory Oceanography Concept Inventory Survey (IO-CIS) serves to fill this gap. Much of the development of the IO-CIS utilized students enrolled in the Spring 2008 Introduction to Oceanography course taught at the University of Colorado at Boulder. The first step in the development of IO-CIS involved the identification and selection of the critical concepts to be addressed in the course and the survey. Next, learning goals were defined for each critical concept. These learning goals then provided the basis for framing open-ended questions that were administered to students in pre-module in-class Concept Inventory Exercises (CIEs). These open-ended questions each underwent validation and revision with expert and novice input prior to being administered in a CIE. Each CIE comprised 4-5 open-ended questions, which each contained 1-4 parts. During the semester, 4 different CIEs were administered, with the number of respondents for each CIE ranging from 57-134. Student responses were then binned according to misconceptions and alternate conceptions, tallied, and "distractors" were written based on the most popular bins using the same language employed by students in their responses. Student responses were also used as part of the validation process to ensure that the questions were interpreted by students in the manner intended. Student responses were also used as a basis to discard particular questions from inclusion in the overall IO-CIS. After the initial IO-CIS questions and distractors had been designed as described above, 23 one-on-one student interviews were conducted as part of the validation process. As a result of the approach employed, a wide variety of student misconceptions and alternate conceptions regarding critical concepts in this Introduction to Oceanography course were revealed and implemented in the design of the IO-CIS. The IO-CIS can now be administered as a pre- and post-instruction survey as a means of assessing students' learning gains in the course for which it was designed. Additionally, there exists potential to further develop the IO-CIS as an assessment tool that may be implemented more broadly in oceanography courses at other institutions.

    It's time! I'm disposing of a 37-year career's worth of books and other scientific materials in geochemistry and oceanography. Ordinarily, reprints of articles have little value. However, in the course of my research, I assembled what may be the world's most comprehensive private collection of articles on marine ferromanganese deposits up to the late 1980s. It includes foreign language materials, especially Russian language articles. Soviet researchers played an active role in this field (I cooperated with them and was a guest of the Soviet Academy).

    In June 2002 the inaugural Physical Oceanography Dissertation Symposium (PODS I) brought together 20 young scientists from 13 different countries. During the meeting, it became apparent that the graduate school experience varied markedly amongst the participants. We critically examine these differences, extract the positive aspects, and create recommendations for a post-graduate experience, which better prepares a student for a career in physical oceanography. We present a summary of the length, content, and quality of education for graduate programs in Australia, France, Germany, the UK, and the USA. Also we address the financial, social, and scientific status of graduate students. While individual character largely determines the success of the PhD experience, graduate programs should address the following crucial factors to improve the student's education: solid mentorship, regular progress checks on a departmental level, course work, internal workshops, field work, communication skills, effective scientific writing, scientific and social integration, international exchange, and stable and sufficient funding. We propose a model four year degree structure with one year of coursework, an additional six months at a foreign institution, and at least one month field work (not necessarily related to the project). If however this work was integral to the project then we feel that an additional fifth year would be appropriate.

  17. Effective, Active Learning Strategies for the Oceanography Classroom

    Dmochowski, J. E.; Marinov, I.

    2014-12-01

    A decline in enrollment in STEM fields at the university level has prompted extensive research on alternative ways of teaching and learning science. Inquiry-based learning as well as the related "flipped" or "active" lectures, and similar teaching methods and philosophies have been proposed as more effective ways to disseminate knowledge in science classes than the traditional lecture. We will provide a synopsis of our experiences in implementing some of these practices into our Introductory Oceanography, Global Climate Change, and Ocean Atmosphere Dynamics undergraduate courses at the University of Pennsylvania, with both smaller and larger enrollments. By implementing tools such as at-home modules; computer labs; incorporation of current research; pre- and post-lecture quizzes; reflective, qualitative writing assignments; peer review; and a variety of in-class learning strategies, we aim to increase the science literacy of the student population and help students gain a more comprehensive knowledge of the topic, enhance their critical thinking skills, and correct misconceptions. While implementing these teaching techniques with college students is not without complications, we argue that a blended class that flexibly and creatively accounts for class size and science level improves the learning experience and the acquired knowledge. We will present examples of student assignments and activities as well as describe the lessons we have learned, and propose ideas for moving forward to best utilize innovative teaching tools in order to increase science literacy in oceanography and other climate-related courses.

    Oceanography and marine ecosystem research are inherently interdisciplinary fields of study that generate and require access to a wide variety of measurements. In late 2006 the Biological and Chemical Oceanography Sections of the National Science Foundation (NSF) Geosciences Directorate Division of Ocean Sciences (OCE) funded the Biological and Chemical Oceanography Data Management Office (BCO-DMO). In late 2010 additional funding was contributed to support management of research data from the NSF Office of Polar Programs Antarctic Organisms & Ecosystems Program. The BCO-DMO is recognized in the 2011 Division of Ocean Sciences Sample and Data Policy as one of several program specific data offices that support NSF OCE funded researchers. BCO-DMO staff members offer data management support throughout the project life cycle to investigators from large national programs and medium-sized collaborative research projects, as well as researchers from single investigator awards. The office manages and serves all types of oceanographic data and information generated during the research process and contributed by the originating investigators. BCO-DMO has built a data system that includes the legacy data from several large ocean research programs (e.g. United States Joint Global Ocean Flux Study and United States GLOBal Ocean ECosystems Dynamics), to which data have been contributed from recently granted NSF OCE and OPP awards. The BCO-DMO data system can accommodate many different types of data including: in situ and experimental biological, chemical, and physical measurements; modeling results and synthesis data products. The system enables reuse of oceanographic data for new research endeavors, supports synthesis and modeling activities, provides availability of "real data" for K-12 and college level use, and provides decision-support field data for policy-relevant investigations. We will present an overview of the data management system capabilities including: map-based and text-based data discovery and access systems; recent enhancements to data search tools; data export and download utilities; and strategic use of controlled vocabularies to facilitate data integration and to improve data system interoperability.

  19. Developments in Airborne Oceanography and Air-Sea Interaction

    NASA Astrophysics Data System (ADS)

    Melville, W. K.

    2014-12-01

    One of the earliest ocean-related flights was that of Amundsen to be first across the North Pole and Arctic from Svalbard to Alaska in the airship Norge in 1926. Twenty five years later Cox & Munk flew a B-17G "Flying Fortress" bomber over Hawaiian waters measuring sea surface slope statistics from photographs of sun glitter and wind speed from a yacht. The value of Cox & Munk's "airborne oceanography" became apparent another twenty five years later with the short-lived Seasat microwave remote-sensing mission, since interpretation of the Seasat data in geophysical variables required scattering theories that relied on their data. The universal acceptance of remote sensing in oceanography began in 1992 with the launch of, and successful analysis of sea surface height data from, the Topex/Poseidon radar altimeter. With that and the development of more realistic coupled atmosphere-ocean models it became apparent that our understanding of weather and climate variability in both the atmosphere and the ocean depends crucially on our ability to measure processes in boundary layers spanning the interface. Ten years ago UNOLS formed the Scientific Committee for Oceanographic Aircraft Research (SCOAR) "...to improve access to research aircraft facilities for ocean sciences"; an attempt to make access to aircraft as easy as access to research vessels. SCOAR emphasized then that "Aircraft are ideal for both fast-response investigations and routine, long-term measurements, and they naturally combine atmospheric measurements with oceanographic measurements on similar temporal and spatial scales." Since then developments in GPS positioning and miniaturization have made scientific measurements possible from smaller and smaller platforms, including the transition from manned to unmanned aerial vehicles (UAVs). Furthermore, ship-launched and recovered UAVs have demonstrated how they can enhance the capabilities and reach of the research vessels, "projecting" research and science, just as aircraft carriers "project force". Now we can measure winds, waves, temperatures, currents, radiative transfer, images and air-sea fluxes from aircraft over the ocean.I will review some of the history of airborne oceanography and present examples of how it can extend our knowledge and understanding of air-sea interaction.

  20. Problems inherent in using aircraft for radio oceanography studies

    Walsh, E. J.

    1977-01-01

    Some of the disadvantages relating to altitude stability and proximity to the ocean are described for radio oceanography studies using aircraft. The random oscillatory motion introduced by the autopilot in maintaining aircraft altitude requires a more sophisticated range tracker for a radar altimeter than would be required in a satellite application. One-dimensional simulations of the sea surface (long-crested waves) are performed using both the JONSWAP spectrum and the Pierson-Moskowitz spectrum. The results of the simulation indicate that care must be taken in trying to experimentally verify instrument measurement accuracy. Because of the relatively few wavelengths examined from an aircraft due to proximity to the ocean and low velocity compared to a satellite, the random variation in the sea surface parameters being measured can far exceed an instrument's ability to measure them.

  1. The role of ocean climate data in operational Naval oceanography

    Local application of global-scale models describes the U.S. Navy's basic philosophy for operational oceanography in support of fleet operations. Real-time data, climatologies, coupled air/ocean models, and large scale computers are the essential components of the Navy's system for providing the war fighters with the performance predictions and tactical decision aids they need to operate safely and efficiently. In peacetime, these oceanographic predictions are important for safety of navigation and flight. The paucity and uneven distribution of real-time data mean we have to fall back on climatology to provide the basic data to operate our models. The Navy is both a producer and user of climatologies; it provides observations to the national archives and in turn employs data from these archives to establish data bases. Suggestions for future improvements to ocean climate data are offered.

  2. Applications of the Coastal Zone Color Scanner in oceanography

    Research activity has continued to be focused on the applications of the Coastal Zone Color Scanner (CZCS) imagery in oceanography. A number of regional studies were completed including investigations of temporal and spatial variability of phytoplankton populations in the South Atlantic Bight, Northwest Spain, Weddell Sea, Bering Sea, Caribbean Sea and in tropical Atlantic Ocean. In addition to the regional studies, much work was dedicated to developing ancillary global scale meteorological and hydrographic data sets to complement the global CZCS processing products. To accomplish this, SEAPAK's image analysis capability was complemented with an interface to GEMPAK (Severe Storm Branch's meteorological analysis software package) for the analysis and graphical display of gridded data fields. Plans are being made to develop a similar interface to SEAPAK for hydrographic data using EPIC (a hydrographic data analysis package developed by NOAA/PMEL).

    After the Challenger expedition (1872-1878), other nations started to show interest in oceanographic research and organizing their own expeditions. As of 1885, Prince Albert I of Monaco conducted oceanographic campaigns with the collaboration of some of the best marine biologists and physical oceanographers of the day, inventing new techniques and instruments for the oceanographic work. Prince Albert's scientific activity certainly helped kindle the interest of his friend, Dom Carlos I, king of Portugal, in the study of the oceans and marine life. Both shared the need to use photography to document their studies. This article analyzes the role of scientific photography in oceanography, especially in the expeditions organized by the Portuguese monarch. PMID:25338032

    Ocean biogeochemistry and marine ecosystem research projects are inherently interdisciplinary and benefit from improved access to well-documented data. Improved data sharing practices are important to the continued exploration of research themes that are a central focus of the ocean science community and are essential to interdisciplinary and international collaborations that address complex, global research themes. In 2006, the National Science Foundation Division of Ocean Sciences (NSF OCE) funded the Biological and Chemical Oceanography Data Management Office (BCO-DMO) to serve the data management requirements of scientific investigators funded by the National Science Foundation’s Biological and Chemical Oceanography Sections. BCO-DMO staff members work with investigators to manage marine biogeochemical, ecological, and oceanographic data and information developed in the course of scientific research. These valuable data sets are documented, stored, disseminated, and protected over short and intermediate time frames. One of the goals of the BCO-DMO is to facilitate regional, national, and international data and information exchange through improved data discovery, access, display, downloading, and interoperability. In May 2010, NSF released a statement to the effect that in October 2010, it is planning to require that all proposals include a data management plan in the form of a two-page supplementary document. The data management plan would be an element of the merit review process. NSF has long been committed to making data from NSF-funded research publicly available and the new policy will strengthen this commitment. BCO-DMO is poised to assist in creating the data management plans and in ultimately serving the data and information resulting from NSF OCE funded research. We will present an overview of the data management system capabilities including: geospatial and text-based data discovery and access systems; recent enhancements to data search tools; data export and download utilities; and strategic use of controlled vocabularies to facilitate data integration and improve interoperability.

    Since its foundation, 100 years ago, the Spanish Institute of Oceanography (IEO) has been observing and measuring the ocean characteristics. Here is a summary of the initiatives of the IEO in the field of the operational oceanography. Some systems like the tide gauges network has been working for more than 70 years. The standard sections began at different moments depending on the local projects, and nowadays there are more than 180 coastal stations and deep-sea ones that are systematically sampled, obtaining physical and biochemical measurements. At this moment, the Observing System includes six permanent moorings equipped with current meters, an open-sea ocean-meteorological buoy offshore Santander and a sea-surface temperature satellite image station. It also supports the Spanish contribution to the Argo international programme with 47 deployed profilers, and continuous monitoring thermosalinometers, meteorological stations and vessel-mounted acoustic Doppler current profilers on the research vessel fleet. The system is completed with the contribution to the Northwest Iberian peninsula and Gibraltar observatories, and the development of regional prediction models. All these systematic measurements allow the IEO to give responses to ocean research activities, official agencies requirements and industrial and main society demands such as navigation, resource management, risks management, recreation, as well as for management development pollution-related economic activities or marine ecosystems. All these networks are linked to international initiatives, framed largely in supranational programmes of Earth observation sponsored by the United Nations or the European Union. The synchronic observation system permits a spatio-temporal description of some events, such as new deep water formation in the Mediterranean Sea and the injection of heat to intermediate waters in the Bay of Biscay after some colder northern storms in winter 2005.

    The Fourth International Conference on Southern Hemisphere Meteorology and Oceanography was held during the week of 29 March-2 April 1993 in Hobart, Tasmania, Australia. The conference was a joint meeting of the American Meteorological Society and the Australian Meteorological and Oceanographic Society and was cosponsored by the Australian Academy of Sciences, the Intergovernmental Oceanographic Commission, and the World Meteorological Organization. There was great interest in the conference, with 398 participants attending from 25 countries, including 92 participants from the Unites States. Student participation was strongly encouraged,and thanks to support from a number of agencies, as many as 60 students were able to attend and actively contribute to the conference. The program included 110 oral and about 200 poster presentations. Each day started with two invited papers in the first morning session, followed by parallel oral sessions later in the morning and most afternoons. These were followed in turn by a poster session on three of the afternoons, with two of these days closed by a keynote address. The presentations were organized around seven major themes: general circulation, climate change, TOGA COARE and tropical studies, chemical cycles, numerical prediction and data analysis, regional studies, and Antarctic environment. The aim of the conference, to encourage greater communication between oceanographers and meteorologists interested in the Southern Hemisphere, was accomplished by including papers from both groups in each of the sessions. This review presents summaries of the invited keynote and invited papers and also briefly describes other activities of the conference.

    The American Meteorological Society (AMS) held its 11th Conference on Satellite Meteorology and Oceanography at the Monona Terrace Convention Center in Madison, Wisconsin, during 15-18 October 2001. The purpose of the conference, typically held every 18 months, is to promote a forum for AMS membership, international scientists, and student members to present and discuss the latest advances in satellite remote sensing for meteorological and oceanographical applications. This year, surrounded by inspirational designs by famed architect Frank Lloyd Wright, the meeting focused on several broad topics related to remote sensing from space, including environmental applications of land and oceanic remote sensing, climatology and long-term satellite data studies, operational applications, radiances and retrievals, and new technology and methods. A vision of an increasing convergence of satellite systems emerged that included operational and research satellite programs and interdisciplinary user groups.The conference also hosted NASA's Electronic Theater, which was presented to groups of middle and high school students totaling over 5500. It was truly a successful public outreach event. The conference banquet was held on the final evening, where a short tribute to satellite pioneer Verner Suomi was given by Joanne Simpson. Suomi was responsible for establishing the Space Science and Engineering Center at the University of Wisconsin in Madison.

    1995-07-01

    A major area of research in fisheries oceanography examines relationships between recruitment dynamics of fish populations and the marine environment. A primary goal is to understand the natural causes of variability in year-class strength of commercially valuable species and apply this knowledge to management [Perry, 1994]. The paradigm that the majority of mortality occurs during transport of early life history stages from spawning to nursery grounds [Rothschild, 1986; Houde, 1987] provides an initial temporal focus for most research. The spatial domain includes the region occupied by early life history stages. Since global climate variability impacts regional ecosystem dynamics, however, the spatial domain often must be expanded. The relative importance and manifestation of biological factors [starvation and predation] that limit survival varies each year. Marked interannual and longer period variations in temperature (an influence on metabolic rates and behavior), transport of planktonic stages, and turbulence can exert an influence on both survival of early life history stages, and distribution of juveniles and adults. To understand how these environmental factors influence reproductive success of fish stocks also requires knowledge of the impact of these factors on predators and prey throughout the food web.

    The Biological and Chemical Oceanography Data Management Office (BCO-DMO) was created to serve PIs principally funded by NSF to conduct marine chemical and ecological research. The new office is dedicated to providing open access to data and information developed in the course of scientific research on short and intermediate time-frames. The data management system developed in support of U.S. JGOFS and U.S. GLOBEC programs is being modified to support the larger scope of the BCO-DMO effort, which includes ultimately providing a way to exchange data with other data systems. The open access system is based on a philosophy of data stewardship, support for existing and evolving data standards, and use of public domain software. The DMO staff work closely with originating PIs to manage data gathered as part of their individual programs. In the new BCO-DMO data system, project and data set metadata records designed to support re-use of the data are stored in a relational database (MySQL) and the data are stored in or made accessible by the JGOFS/GLOBEC object- oriented, relational, data management system. Data access will be provided via any standard Web browser client user interface through a GIS application (Open Source, OGC-compliant MapServer), a directory listing from the data holdings catalog, or a custom search engine that facilitates data discovery. In an effort to maximize data system interoperability, data will also be available via Web Services; and data set descriptions will be generated to comply with a variety of metadata content standards. The office is located at the Woods Hole Oceanographic Institution and web access is via http://www.bco-dmo.org.

    The beginning of 2013 will mark the start for the Project BLUE, one of the greatest efforts in operational oceanography ever proposed in Brazil. The region of interest is located in the continental shelf break between Cabo Frio (23S) and Floriananpolis Island (28S). The region is dominated by the Brazil Current system, formed by the Brazil Current, carrying Tropical Water southward from surface down to 400-500 meters and the Intermediate Counter Current, flowing northward in the interface of the South Atlantic Central Water and the Antarctic Intermediate Water. In situ data and operational forecasts efforts in this oil rich region are still few and disperse. Nevertheless, the constant increase of offshore operations is followed by the necessity of both a baseline study and a systematic data collection. All project structure is aimed at optimizing real-time data collection and displaying. Project BLUE is formed by 4 modules: (1) In situ data collection will be performed by 5 gliders, 108 surface drifters and 36 subsurface profiling floats. (2) Remote Sensing module count on a local receiving antenna to provide operational information of Sea Surface Temperature, Height and Ocean Color. (3) Numerical Modelling module aims, initially, to implement a regional grid for long climatological runs, followed by an operational run, with assimilation of the data generated by the first module. One of the great concerns of the Project BLUE is to turn public all collected data, allowing for a greater number of researchers to access the data and, consequently, improving the knowledge on the region. For that purpose, there is an specific module (4) Data displaying focused on easing the access to the data via web services. It is expected, by the end of the first three years, to have a systematic data collection system, a well adapted assimilation scheme and an operational forecast model for the Santos Basin, providing reliable information for offshore operations and emergency planning.

  16. Enhancing Oceanography Classrooms with "Captive and Cultured" Ocean Experiences

    Students in oceanography classes often request more direct exposure to actual ocean situations or field trips. During regular session (13 week) or shorter term (4 week) summer classes such long trips are logistically difficult owing to large numbers of students involved or timing. This new approach to such a course supplement addresses the requests by utilizing local resources and short field trips for a limited number of students (20) to locations in which Ocean experiences are available, and are often supported through education and outreach components. The vision of the class was a mixture of classroom time, readings, along with paper and actual laboratories. In addition short day-long trips to locations where the ocean was "captured" were also used to supplement the experience as well as speakers involved with aquaculture ("cultivated") . Central Virginia is a fortunate location for such a class, with close access for "day travel" to the Chesapeake Bay and numerous field stations, museums with ocean-based exhibits (the Smithsonian and National Zoo) that address both extant and extinct Earth history, as well as national/state aquaria in Baltimore, Washington and Virginia Beach. Furthermore, visits to local seafood markets at local grocery stores, or larger city markets) enhance the exposure to productivity in the ocean, and viability of the fisheries sustainability. The course could then address not only the particulars of the marine science, but also aspects of ethics, including keeping animals in captivity or overfishing of particular species and the special difficulties that arise from captive or culturing ocean populations. In addition, the class was encouraged to post web-based journals of experiences in order to share opinions of observations in each of the settings.

    Both maternal 25-hydroxyvitamin D (25(OH)D) concentrations during pregnancy and placental amino acid transporter gene expression have been associated with development of the offspring in terms of body composition and bone structure. Several amino acid transporter genes have vitamin D response elements in their promoters suggesting the possible linkage of these two mechanisms. We aimed to establish whether maternal 25(OH)D and vitamin D-binding protein (VDBP) levels relate to expression of placental amino acid transporters. RNA was extracted from 102 placental samples collected in the Southampton Women's Survey, and gene expression was analysed using quantitative real-time PCR. Gene expression data were normalised to the geometric mean of three housekeeping genes, and related to maternal factors and childhood body composition. Maternal serum 25(OH)D and VDBP levels were measured by radioimmunoassay. Maternal 25(OH)D and VDBP levels were positively associated with placental expression of specific genes involved in amino acid transport. Maternal 25(OH)D and VDBP concentrations were correlated with the expression of specific placental amino acid transporters, and thus may be involved in the regulation of amino acid transfer to the fetus. The positive correlation of VDBP levels and placental transporter expression suggests that delivery of vitamin D to the placenta may be important. This exploratory study identifies placental amino acid transporters which may be altered in response to modifiable maternal factors and provides a basis for further studies. PMID:25940599

    A new satellite mission called Surface Water and Ocean Topography (SWOT) has been developed jointly by the U.S. National Aeronautics and Space Administration and France's Centre National d'Etudes Spatiales. Based on the success of nadir-looking altimetry missions in the past, SWOT will use the technique of radar interferometry to make wide-swath altimetric measurements of the elevation of surface water on land and the ocean's surface topography. The new measurements will provide information on the changing ocean currents that are key to the prediction of climate change, as well as the shifting fresh water resources resulting from climate change. Conventional satellite altimetry has revolutionized oceanography by providing nearly two decades' worth of global measurements of ocean surface topography. However, the noise level of radar altimeters limits the along-track spatial resolution to 50-100 km over the oceans. The large spacing between the satellite ground tracks limits the resolution of 2D gridded data to 200 km. Yet most of the kinetic energy of ocean circulation takes place at the scales unresolved by conventional altimetry. About 50% of the vertical transfer of heat and chemical properties of the ocean (e.g., dissolved CO2 and nutrients) is also accomplished by processes at these scales. SWOT observations will provide the critical new information at these scales for developing and testing ocean models that are designed for predicting future climate change. SWOT measurements will be in Ka band (~35 GHZ), chosen for the radar to achieve high precision with a much shorter inteferometry baseline of 10 m. Small look angles (~ 4 degrees) are required to minimize elevation errors, which limits the swath width to 120 km. An orbit with inclination of 78 degrees and 22 day repeat period was chosen for gapless coverage and good tidal aliasing properties. With this configuration, SWOT is expected to achieve 1 cm precision at 1 km x 1 km pixels over the ocean and 10 cm precision over 50 m x 50 m pixels over land waters. This presentation will be in two parts. Firstly we will give a brief overview of the SWOT mission and its sampling characteristics. We will then introduce a number of recent scientific results on our present understanding of ocean topography and surface geostropic velocities at mesoscales and sub-mesoscales, results which have been inspired by the upcoming SWOT measurements.

    We report on the work plan of the SMOS+Surface Ocean Salinity and Synergy (SMOS+SOS) project. SMOS+SOS is funded through the Support to Science Element (STSE) component of the European Space Agency's (ESA) Earth Observation Envelope Programme. The SMOS+SOS consortium consists of four organisations namely the National Oceanography Centre (UK), the LOCEAN/IFREMER/CATDS research team (France), the Met Office (UK) and Satellite Oceanographic Consultants Ltd (UK). The end of the SMOS+SOS project will be marked by a final open workshop most likely hosted by the UK Met Office in September/October 2014. The project is concerned with demonstrating the performance and scientific value of SMOS Sea Surface Salinity (SSS) products through a number of well-defined case studies. The case studies include: Amazon/Orinoco plumes (freshwater outflow); Agulhas and Gulf Stream (strong water mass boundary); Tropical Pacific/Atlantic (strong precipitation regime); sub-tropical North Atlantic (ie SPURS; strong evaporative regime); and Equatorial Pacific (equatorial upwelling). With SMOS measuring the SSS in the top cm of the ocean, validating SMOS against in situ salinity data taken typically at a few meters depth introduces assumptions about the vertical structure of salinity in the upper ocean. To address these issues, the project will examine and quantify discrepancies between SMOS and in situ surface salinity data at various depths in different regions characterised by strong precipitation or evaporation regimes. Equally, data editing and spatio-temporal averaging play a central role in determining the quality, errors and correlations in SMOS SSS data. The project will explore various processing and spatio-temporal averaging choices to define the SMOS SSS products that best address the needs of the oceanographic and data assimilation user community. One key aspect of this project is to determine how one can achieve useful accuracy/uncertainty in SSS without jeopardising SMOS's ability to capture rapidly-varying or small scale features such as rain cells or the mesoscale variability associated with river plumes and major western boundary currents. Finally, the study explores the ability of SMOS SSS to provide insights into new oceanographic processes when used in synergy with other data. Hence, synergy with Aquarius will be used to seek evidence of the possible impact of diurnal warming on the SMOS SSS data, and to explore differences in the salinity signatures of Tropical Instability Waves observed in the Pacific with SMOS and Aquarius.

    The TOPEX/Poseidon and Jason-1 ocean altimeter missions offer the educator in the middle school or informal education venue a unique opportunity for reinforcing ocean science studies. Two new educational posters from the United States' NASA/Jet Propulsion Laboratory and France's Centre National d'Etudes Spatiales provide teachers and students a tool to examine topics such as the dynamics of ocean circulation, ocean research, and the oceans role in climate. "Voyage on the High Seas; A Jason-1 Oceanic Adventure" is a poster/board game that offers learning opportunities through a non-textbook activity designed to stimulate interest in ocean science in a fun and instructive environment. The object of the game is to be the first to sail your research vessel from the Mediterranean Sea to Seattle, Washington while gaining Discovery Points. The starting point in the Mediterranean is where the mythological adventurers Jason and the Argonauts set out on their epic voyage to find the golden fleece. Discovery and Quiz Cards are used to challenge players to gain knowledge and points by correctly answering questions using clues from the board. Teachers can directly photocopy additional activities from the reverse side of the board game for use in a middle school Earth science curriculum. The game is also a stand-alone poster that is an engaging world map depicting the world's oceans and continents, major ocean currents, and other important geographic features. A second poster has been developed as a joint JPL/CNES effort. "Oceans' Music: Climate's Dance" highlights the ocean/climate link and provides educational activities that can be used directly in the classroom. The eye-catching poster is appropriate for display in both the formal and informal education setting. In both venues it should stimulate conversation about the ocean and provide a point of entry into inquiry-based learning about the connections between ocean circulation and global climate. It also seeks to emphasize the role of the ocean in sustaining life on Earth. Activities on the back of the poster can be used as supplemental material in a middle school Earth science curriculum, and are suitable for individual instruction and for classroom or group exercises. This poster will be published in both English and French. Educational research indicates that an inquiry-based method of student engagement is an appropriate and effective teaching tool. These posters offer a fun and instructive environment to promote student interest in Earth Science in general and particularly in oceanography.

    The Summer Undergraduate Research Fellowships in Oceanography (SURFO) program at the Graduate School of Oceanography/University of Rhode Island is an NSF-funded Research Experience for Undergraduates site program with a programmatic research niche focused on quantitative aspects of Oceanography. Each summer-cohort includes 9-12 participants (rising seniors) who are paired with a primary research advisor and often with a graduate student mentor. The primary components of the 10-week program include a 4-week introductory phase and a 6-week core research phase. A retrospective self-assessment instrument gauged the confidence, attitude and comfort level of participants with; 1) core math and science subjects, 2) oceanography-related subjects, 3) research skills, and 4) SURFO and GSO staff. SURFO participants evaluated themselves at the start of the program, after the introductory phase, and at the end of the program. Participants were also asked to reassess their initial evaluations and provide an updated score. The pre-assessment results indicate that the program recruits students from the target group (e.g., strong physics and math backgrounds, but with limited exposure to oceanography). The results also indicate that the students are initially comfortable with their advising team, but not so comfortable with their research topic and research skills. The post-introductory phase results indicate large increases in comfort level with the advising team and the local research community yet little or no change is indicated for research skills. The final assessments show large changes in oceanography-content knowledge, research topic, and research skills. The retrospective reassessment indicates an initial overconfidence in most categories. Overall, the largest changes occurred during the core research portion of the program. These results reinforce the importance/effectiveness of authentic, hands-on, inquiry-based research for higher learning and training the next generation of scientists.

  3. A perspective on the future of physical oceanography.

    PubMed

    Garabato, Alberto C Naveira

    The ocean flows because it is forced by winds, tides and exchanges of heat and freshwater with the overlying atmosphere and cryosphere. To achieve a state where the defining properties of the ocean (such as its energy and momentum) do not continuously increase, some form of dissipation or damping is required to balance the forcing. The ocean circulation is thought to be forced primarily at the large scales characteristic of ocean basins, yet to be damped at much smaller scales down to those of centimetre-sized turbulence. For decades, physical oceanographers have sought to comprehend the fundamentals of this fractal puzzle: how the ocean circulation is driven, how it is damped and how ocean dynamics connects the very different scales of forcing and dissipation. While in the last two decades significant advances have taken place on all these three fronts, the thrust of progress has been in understanding the driving mechanisms of ocean circulation and the ocean's ensuing dynamical response, with issues surrounding dissipation receiving comparatively little attention. This choice of research priorities stems not only from logistical and technological difficulties in observing and modelling the physical processes responsible for damping the circulation, but also from the untested assumption that the evolution of the ocean's state over time scales of concern to humankind is largely independent of dissipative processes. In this article, I illustrate some of the key advances in our understanding of ocean circulation that have been achieved in the last 20 years and, based on a range of evidence, contend that the field will soon reach a stage in which uncertainties surrounding the arrest of ocean circulation will pose the main challenge to further progress. It is argued that the role of the circulation in the coupled climate system will stand as a further focal point of major advances in understanding within the next two decades, supported by the drive of physical oceanography towards a more operational enterprise by contextual factors. The basic elements that a strategy for the future must have to foster progress in these two areas are discussed, with an overarching emphasis on the promotion of curiosity-driven fundamental research against opposing external pressures and on the importance of upholding fundamental research as the apex of education in the field.

  4. Using Earth Data in an Introductory Oceanography Course

    NASA Astrophysics Data System (ADS)

    Prothero, W. A.

    2002-12-01

    Activities that engage students in the use and interpretation of real earth data provide an effective way of promoting an understanding of the science process. In UCSB's introductory Oceanography course, major goals are to improve student understanding of how science works and how to interpret science claims in the popular media. Activities are modeled after those of practicing scientists. These include: a) posing a solvable problem, b) choosing and acquiring relevant data, c) describing the data, d) interpreting the data, e) giving talks to peers, and f) publishing and reviewing findings. Each of these activities poses pedagogical challenges that must be addressed in carefully sequenced course assignments that build upon each other, and respond to a variety of learning styles. The use of earth data in education also presents significant challenges in creating effective data acquisition and display tools. However, only item b, above, is pertinent to these tools. The other items present similar challenges. During the course, learners must acquire enough subject knowledge to successfully interpret the data. They must understand the theory or model they are testing, how the relevant data can be used to test the model, and how to illustrate and present their findings orally and in writing. Some of the assignments that support this are: online homework, online subject area mini-quizzes (randomly created from a database of questions), "questions of the day" in lecture, online short answer thought questions, lab section guided mini-investigations, lab section group presentations, short writing exercises, and 2 longer writing assignments. Students rate the writing assignments as the most effective course component that contributes to their learning. The writing assignments focus student effort and also produce a product that we can study in an attempt to measure student learning. Prof. Gregory Kelly and Prof. Charles Bazerman (UCSB Graduate School of Education) are studying student papers using rhetorical analysis and are developing a model that we hope will allow us to reliably measure the quality of a student paper, and also measure student understanding of science process. We are also using the results of these studies to refine the way we teach the science writing process to students.

  5. Strategies for Assessing Learning Outcomes in an Online Oceanography Course

    NASA Astrophysics Data System (ADS)

    Reed, D. L.

    2003-12-01

    All general education courses at the San Jose State University, including those in the sciences, must present a detailed assessment plan of student learning, prior to certification for offering. The assessment plan must state a clear methodology for acquiring data on student achievement of the learning outcomes for the specific course category, as well as demonstrate how students fulfill a strong writing requirement. For example, an online course in oceanography falls into the Area R category, the Earth and Environment, through which a student should be able to demonstrate an understanding of the methods and limits of scientific investigation; distinguish science from pseudo-science; and apply a scientific approach to answer questions about the Earth and environment. The desired learning outcomes are shared with students at the beginning of the course and subsequent assessments on achieving each outcome are embedded in the graded assignments, which include a critical thinking essay, mid-term exam, poster presentation in a symposium-style format, portfolio of web-based work, weekly discussions on an electronic bulletin board, and a take-home final exam, consisting of an original research grant proposal. The diverse nature of the graded assignments assures a comprehensive assessment of student learning from a variety of perspectives, such as quantitative, qualitative, and analytical. Formative assessment is also leveraged into learning opportunities, which students use to identify the acquisition of knowledge. For example, pre-tests are used to highlight preconceptions at the beginning of specific field studies and post-testing encourages students to present the results of small research projects. On a broader scale, the assessment results contradict common misperceptions of online and hybrid courses. Student demand for online courses is very high due to the self-paced nature of learning. Rates of enrollment attrition match those of classroom sections, if students are informed of the instructor's expectations at the beginning of the course. The level of faculty-student and student-student communication is very high, both in terms of quantity and quality, and exceeds that experienced in classroom sections. Student scores on graded assignments compare favorably to classroom sections. Overall, online courses offer a cost-effective means of addressing top priority issues, including increasing student access to learning, accelerating rates of graduation, and improving outreach to K-12 educators, especially those working on credential requirements.

  6. Distribution and Abundance of Interstitial Ciliates in Southampton Water in Relation to Physicochemical Conditions, Metal Pollution and the Availability of Food Organisms

    Sediment samples were collected at low tide from eight sandy and muddy shores around Southampton Water on one occasion in July and one occasion in September. The temperature and pH of the sediments were measured at the time of collection, the water content of the sediments was determined and samples subjected to granulometric analysis. The population densities of bacteria and microflagellates were determined and the ciliates in sub-samples were identified to genus level and enumerated. The concentrations of cadmium, copper, lead, mercury and nickel in the interstitial water and in the dried sediments were measured by the dithizone and atomic absorption methods, respectively. These metal concentrations were compared with literature values for other British estuaries. Ciliates belonging to 23 genera were found in the sediments, the diversity of ciliates varying widely between stations. Bacterial numbers (mean ˜5×10 8 cm -3) at the various stations correlate with the surface area of the sediment particles and also correlate weakly with flagellate numbers (mean ˜2×10 4 cm -3). Total ciliate numbers (mean ˜1×10 3 cm -3) correlated quite strongly with flagellate numbers, but not with bacterial numbers. Euplotes, Strombidiumand Uronemawere common at all stations and generally dominated; Didinium, Mesodinium pulexand Pleuronemawere also found at all stations, and the latter two were often numerous; Uronychiawas found at seven stations. The distributions of Acinetopsis, Blepharisma, Lacrymaria, M. pulex, Paramecium, Spirostomum, Strombidiumand Vorticellashowed similar correlations to one another, and tended to favour sites nearer to sources of freshwater; these ciliates also showed a correlation with pH, river waters locally being alkaline. None of the ciliates showed correlations with any physical characteristics of the sediments. There were no negative correlations of ciliate distributions with metal pollutants. The levels of metal pollutants found in water drained from the sediments do not exceed concentrations to which laboratory cultures of Euploteshave been found to acquire tolerance.

  7. Operational Oceanography In A Coastal Zone: The Gulf of Trieste

    NASA Astrophysics Data System (ADS)

    Viezzoli, D.; Deponte, D.; Ursella, L.

    The gulf of Trieste, the northernmost part of the Adriatic Sea, is characterized by an horizontal dimension of 25 km and a maximum bottom depth of 25 m. Here very highly variable forcings are observed: strong NNE wind events, large seasonal varia- tions of heat flux which cause complete vertical mixing in winter and a marked strat- ification in summer; also fluvial and ground water runoff renders the gulf a ROFI. Furthermore, the highest tidal range in the Mediterannean Sea is observed here, and recurrent severe SE and SW sea storms induce seiches and waves able to erode the sandy beaches of the northern coast. Among the aspects of physical oceanography in the gulf to be addressed: the complex circulation due to the wind regime and the presence of 3 layers in the warm season, the formation of dense water in the cold one, and the small scale dynamics (plumes dynamics, horizontal and vertical shear). To ob- serve and study so many processes in their wide spectrum of time scales, a traditional experimental approach is not sufficient: systematic, long-term routine measurements of the basic meteo-oceanographic variables, are needed. In 1998, the OGS developed a meteo-oceanographic buoy, named MAMBO, equipped with a profiling multipara- metric probe flanked by a sea-bottom ADCP-300kHz, and deployed it at a site 1 km distant from the coast. The buoy data are sampled every 3 hours. From March 2001 wave motion data are being collected by a Datawell Directional Waverider (DWR) just outside the gulf. From June 2001, an ADCP-600kHz remotely controlled by means of an original device is flanking the MAMBO buoy. The configuration of the ADCP can be remotely changed to resolve the effects of the stratification on the vertical structure of the tidal and the wind induced currents or, occasionally, to record shoaling wave data that can be compared with the DWR ones. The systematic monitoring provides a better understating of the transport and of the vertical mixing in the coastal bound- ary layer within the gulf. Both the MAMBO data and the ADCP data are transmitted to land in near-real-time and disseminated on the Internet: these features of the op- erational setup allow opportune planning of field activity, when special situations are observed in the probe or the current data. Some preliminary vessel-mounted ADCP transects have also been performed in the 2001, in view of a wider and more frequent use, to obtain more insight on the circulation. The operational application of a 3D cir- culation model for nowcasting/forecasting purposes is being planned. Two 2D wave propagation models will be used in the frame of a coastal erosion study.

    In the framework of the GODAE OceanView program, and efforts supported through funded projects like the EU MyOcean/MyOcean-2/MyOcean-FO activities, validation and scientific assessment of ocean operational systems are witnessing noticeable progresses. In particular concerning the community shared assessment activities. Collaborations, through working group, have raised for implementation validation common practices. Through GODAE OceanView two real-time inter comparison tasks are carried on, with international contributions of most advances global operational centres: the so-called «class 4» inter comparison activity allows real time monitoring performance of temperature, salinity, sea-ice and sea level parameters. In parallel, linked with the CLIVAR/GSOP efforts, inter comparison of reanalysis is providing a framework for future multi-model ocean climate monitoring. At the European level, operational centres are working together in order to 1) define in common ways best practices for operational cal/val activities; 2) implement and test performance assessment in real time and off-line; and 3) offer to GMES/Copernicus users reliable information on operational ocean product quality. Exemples of recent development are provided here, together with a prospective overview of cal/val practices.

    The U.S. Navy's Fleet Numerical Meteorology and Oceanography Center (FNMOC; see http://www.fnmoc.navy.mil/), located in Monterey, CA, is the lead activity within the U.S. Department of Defense (DoD) for numerical weather prediction and coupled air-sea modeling. FNMOC fulfills this role through means of a suite of sophisticated global and regional meteorological and oceanographic (METOC) models, extending from the top of the atmosphere to the bottom of the ocean, which is supported by one of the world's most complete real-time METOC databases. Fleet Numerical operates around-the-clock, 365 days per year and distributes METOC products to military and civilian users around the world, both ashore and afloat, through a variety of means, including a rapidly growing and innovative use of Web technology. FNMOC's customers include all branches of the Department of Defense (DoD), other government organizations such as the National Weather Service, private companies such as the Weather Channel, a number of colleges and universities, and the general public. FNMOC acquires and processes over 6 million METOC observations per day—creating one of the world's most comprehensive real-time databases of meteorological and oceanographic observations for assimilation into its models. FNMOC employs three primary models, the Navy Operational Global Atmospheric Prediction System (NOGAPS), the Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS), and the WaveWatch III model (WW3), along with a number of specialized models and related applications. NOGAPS is a global weather model, driving nearly all other FNMOC models and applications in some fashion. COAMPS is a high-resolution regional model that has proved to be particularly valuable for forecasting weather and ocean conditions in highly complex coastal areas. WW3 is a state-of-the-art ocean wave model that is employed both globally and regionally in support of a wide variety of naval operations. Specialized models support and supplement the main models with predictions of ocean thermal structure, ocean currents, and other important data. In general, FNMOC strives to treat the air-ocean environment as a fully integrated system, from the top of the atmosphere to the bottom of the ocean, placing special emphasis on the air-ocean interface. FNMOC also hosts the USGODAE Server (see http://www.usgodae.org). Ongoing development of this system is being done through a partnership of FNMOC and NOAA's Pacific Marine Environmental Lab (PMEL), with oversight from the U.S. Global Ocean Data Assimilation Experiment (GODAE) Steering Committee and funding from the Office of Naval Research (ONR). The USGODAE Server hosts in-situ oceanographic data, atmospheric forcing fields suitable for driving ocean models and unique GODAE data sets, including demonstration ocean model products. The USGODAE Server contains fixed and drifting buoy data, bathythermograph data, PALACE float data, ship data and CMAN data. It also includes TOPEX, GFO, and ERS altimeter data, AVHRR SST retrievals, DMSP sea ice concentration retrievals and meteorological observations. The USGODAE Server also functions as one of two global repositories or Global Data Assembly Centers (GDACs) for data from the Argo global array of temperature/salinity profiling floats. Included in these online data sets are those from Canada (MEDS) with 67 floats and 1900 station files from April 2001 to present, Japan (JMA) with 97 floats and 2700 station files from April 2000 to present, and the U.S. (AOML) with 304 floats and 9800 station files from August 1997 to present, and France (CORIOLIS) with 121 floats and 5396 station files from early 2001 to present. On the USGODAE Server the Argo GDAC Web Interface allows users to easily select data based on time, region, Data Assembly Center (DAC), or float ID. Users can download float profile files, trajectory files, or technical data files. The atmospheric forcing fields hosted on the USGODAE Server are from both FNMOC and the National Centers for Environmental Prediction (NCEP). The FNMOC fields include output from both NOGAPS and COAMPS, with the COAMPS products obtained from the four regional areas surrounding the continental United States. Additionally, the server mirrors the METEO France Satellite Application Facility (SAF) ftp site, which provides surface radiative fluxes, wind vectors, sea-surface temperature fields, and sea ice. To facilitate access and visualization of USGODAE data sets, PMEL has developed the GODAE Live Access Server (LAS) software. LAS enables the Web user to visualize data with on-the-fly graphics, request custom subsets of variables in a choice of file formats, access background reference material about the data (i.e., metadata), and compare (e.g., difference) variables from different data sets. The USGODAE Server also uses the Grid Analysis and Display System (GrADS)/Distributed Oceanographic Data System (DODS) software from the Center for Ocean Land Atmosphere (COLA)/Institute of Global Environment and Society (IGES), serving NOGAPS, COAMPS and NCEP fields as time-aggregated DODS data sets. A thumbnail generator creates preview images for all non-gridded data files on the server, giving users the opportunity to view the contents of large in-situ and satellite data files before downloading them. The USGODAE Server has become a ``one-stop shop" for GODAE researchers and others requiring data to support global ocean modelling studies. As the execution phase for GODAE approaches, additional data sets and data access capabilities will be added to the server. An exciting new aspect of this will be the inclusion of demonstration model products produced by GODAE ocean modelers from around the world. As the server is populated with these products, it is expected to become a significant enabler and focal point for ocean model inter-comparison studies.

  10. The epistemological framing of a discipline: Writing science in university oceanography

    NASA Astrophysics Data System (ADS)

    Kelly, Gregory J.; Chen, Catherine; Prothero, William

    2000-09-01

    The purpose of this paper is to examine how instruction in scientific writing in a university oceanography course communicated epistemological positions of this discipline. Drawing from sociological and anthropological studies of scientific communities, this study uses an ethnographic perspective to explore how teachers and students came to define particular views of disciplinary knowledge through the everyday practices associated with teaching and learning oceanography. Writing in a scientific genre was supported by interactive CD-ROM which allowed students to access data representations from geological databases. In our analysis of the spoken and written discourse of the members of this course, we identified epistemological issues such as uses of evidence, role of expertise, relevance of point of view, and limits to the authority of disciplinary inquiry. Implications for college science teaching are drawn.

    The demand for elderly centre has increased tremendously abreast with the world demographic change as the number of senior citizens rose in the 21st century. This has become one of the most crucial problems of today's era. As the world progress into modernity, more and more people are occupied with daily work causing the senior citizens to lose the care that they actually need. This paper seeks to elucidate the best possible design of an elderly care centre with new approach in order to provide the best service for them by analysing their needs and suitable activities that could elevate their quality of life. All these findings will then be incorporated into design solutions so as to enhance the living environment for the elderly especially in Malaysian context.

  15. Woman-centred care.

    2001-04-01

    Changes over the past decade have emphasised the individual service user and their relationship with the health service. Within the maternity services this has been interpreted as woman-centred care a result of key initiatives; the Winterton Report (House of Commons, 1992. Maternity Services. Second Report of the Health Committee (Winterton Report), Vol. 1. HMSO, London) and Changing Childbirth (DoH, 1993a, Changing childbirth: reports of the expert maternity group parts 1 & 2. HMSO, London). Changing Childbirth outlined key principles of the maternity services and the need for the woman (and her partner, if she wishes) to be the focus of care. The key principles are choice, continuity and control. High quality care depends on the recognition of individuals as having unique needs which continues to be reflected within contemporary policy documents (DoH, 1997, The new NHS: modern and dependable. HMSO, London). This paper presents findings related to the provision of woman-centred care from a national research and development study. The study design incorporated (i): a national survey which was undertaken with midwives, midwife supervisors and doctors; and (ii): in-depth case studies in which information was obtained through interviews with midwives, midwife supervisors, educators, managers, doctors and mothers. Midwives, at all levels, are involved in changing maternity service provision and adapting to new systems of care which aim to increase continuity of care and carer for the woman. The researchers sought to understand how woman-centred care was interpreted and experienced in practice. The findings have been used to identify the continuing educational needs of midwives, and to develop an open learning educational package to meet identified need. The curriculum was designed to enhance the move towards the provision of a more integrated woman-centred service. PMID:11223063

  16. Centrosomes as signalling centres

    PubMed Central

    Arquint, Christian; Gabryjonczyk, Anna-Maria; Nigg, Erich A.

    2014-01-01

    Centrosomes—as well as the related spindle pole bodies (SPBs) of yeast—have been extensively studied from the perspective of their microtubule-organizing roles. Moreover, the biogenesis and duplication of these organelles have been the subject of much attention, and the importance of centrosomes and the centriole–ciliary apparatus for human disease is well recognized. Much less developed is our understanding of another facet of centrosomes and SPBs, namely their possible role as signalling centres. Yet, many signalling components, including kinases and phosphatases, have been associated with centrosomes and spindle poles, giving rise to the hypothesis that these organelles might serve as hubs for the integration and coordination of signalling pathways. In this review, we discuss a number of selected studies that bear on this notion. We cover different processes (cell cycle control, development, DNA damage response) and organisms (yeast, invertebrates and vertebrates), but have made no attempt to be comprehensive. This field is still young and although the concept of centrosomes and SPBs as signalling centres is attractive, it remains primarily a concept—in need of further scrutiny. We hope that this review will stimulate thought and experimentation. PMID:25047618

    2007-12-01

    Now in its fourth year, "In the Footsteps of Roger Revelle" (IFRR) is a middle school science education program that draws student interest, scientific content and coherence with National Science Standards from real-time research at sea in fields of physical science. As a successful collaboration involving Scripps Institution of Oceanography (SIO), Woods Hole Oceanographic Institution (WHOI), National Oceanic and Atmospheric Administration (NOAA), Office of Naval Research (ONR), National Science Foundation (NSF), San Diego County Office of Education (SDCOE), and San Marcos Middle School (SMMS), IFRR brings physical oceanography and related sciences to students at the San Marcos Middle School in real-time from research vessels at sea using SIO's HiSeasNet satellite communication system. With their science teacher on the ship as an education outreach specialist or ashore guiding students in their interactions with selected scientists at sea, students observe shipboard research being carried out live via videoconference, daily e-mails, interviews, digital whiteboard sessions, and web interaction. Students then research, design, develop, deploy, and field-test their own data-collecting physical oceanography instruments in their classroom. The online interactive curriculum encourages active inquiry with intellectually stimulating problem-solving, enabling students to gain critical insight and skill while investigating some of the most provocative questions of our time, and seeing scientists as role- models. Recent science test scores with IFRR students have shown significant increases in classes where this curriculum has been implemented as compared to other classes where the traditional curriculum has been used. IFRR has provided students in the San Diego area with a unique opportunity for learning about oceanographic research, which could inspire students to become oceanographers or at least scientifically literate citizens - a benefit for a country that depends increasingly on technically proficient personnel, and a benefit for society at large.

    1973-01-01

    The author has identified the following significant results. Results of studies of the oceanography of the northern Gulf of California (Mexico) are reported. A remote, instrumented buoy measuring and telemetering oceanographic data by ERTS-1 satellite was designed, constructed, deployed, and tested. Regular cruises by a research ship on a pattern of 47 oceanographic stations collected data which are analyzed and referenced to analysis of ERTS-1 satellite imagery. A thermal dynamic model of current patterns in the northern Gulf of California is proposed. Findings are examined in relation to the model.

    Considerable research has compared how students learn science from computer simulations with how they learn from traditional classes. Little research has compared how students learn science from computer simulations with how they learn from direct experience in the real environment on which the simulations are based. This study compared two college classes studying introductory oceanography. One class learned using an interactive computer simulation based on a dynamic, three-dimensional model of physical oceanography. The other class learned by spending a day on a research ship using scientific tools and instruments to measure physical properties of the ocean directly. In classes preceding and following the simulation or field experience, students performed the same exercises regarding currents and salinity, had the same instructor presentations, and did the same homework. The study found that the field experience helped contextualize learning for students with little prior experience of the ocean while the simulation made it easier for students to connect what they learned from it to other content they learned in class. These and other findings shed light on what computer simulations can and cannot help students learn, and what concepts are best learned in the real environment.

  1. Polar Seas Oceanography: An Integrated Case Study of the Kara Sea

    NASA Astrophysics Data System (ADS)

    Harms, Ingo

    2004-02-01

    What strikes first when browsing through this book is that the main title is misleading. Polar Seas Oceanography is, first of all, a book on ``an integrated case study of the Kara Sea,'' as the subtitle says. For readers who are interested more generally in polar oceanography, the book is probably the wrong choice. The Kara Sea is a rather shallow shelf sea within the Arctic Ocean, located between the Barents Sea to the west and the Laptev Sea to the east. The importance of the Kara Sea is manifold: climate change issues like ice formation and freshwater runoff, environmental problems from dumping of radioactive waste or oil exploitation, and finally, the Northern Sea route, which crosses large parts of the Kara Sea, underline the economical and ecological relevance of that region. In spite of severe climate conditions, the Kara Sea is relatively well investigated. This was achieved through intense oceanographic expeditions, aircraft surveys, and polar drift stations. Russian scientists from the Arctic and Antarctic Research Institute (AARI) carried out a major part of this outstanding work during the second half of the last century.

  2. The Indigo V Indian Ocean Expedition: a prototype for citizen microbial oceanography

    Microbial Oceanography has long been an extremely expensive discipline, requiring ship time for sample collection and thereby economically constraining the number of samples collected. This is especially true for under-sampled water bodies such as the Indian Ocean. Specialised scientific equipment only adds to the costs. Moreover, long term monitoring of microbial communities and large scale modelling of global biogeochemical cycles requires the collection of high-density data both temporally and spatially in a cost-effective way. Thousands of private ocean-going vessels are cruising around the world's oceans every day. We believe that a combination of new technologies, appropriate laboratory protocols and strategic operational partnerships will allow researchers to broaden the scope of participation in basic oceanographic research. This will be achieved by equipping sailing vessels with small, satcom-equipped sampling devices, user-friendly collection techniques and a 'pre-addressed-stamped-envelope' to send in the samples for analysis. We aim to prove that 'bigger' is not necessarily 'better' and the key to greater understanding of the world's oceans is to forge the way to easier and cheaper sample acquisition. The ultimate goal of the Indigo V Expedition is to create a working blue-print for 'citizen microbial oceanography'. We will present the preliminary outcomes of the first Indigo V expedition, from Capetown to Singapore, highlighting the challenges and opportunities of such endeavours.

  3. Epistemic levels in argument: An analysis of university oceanography students' use of evidence in writing

    NASA Astrophysics Data System (ADS)

    Kelly, Gregory J.; Takao, Allison

    2002-05-01

    The purpose of this paper is to examine university oceanography students' use of evidence in writing. Drawing from rhetorical studies of science writing and studies of argumentation in science education, a model for assessing students' arguments is proposed that considers the relative epistemic status of propositions comprising students' written texts. The study was conducted in an introductory university oceanography course in a large public university that utilized an interactive CD-ROM that provided geological data sets for student exploration of scientific questions. Student arguments were analyzed through a process of sorting propositions by epistemic level and identifying the explicit links within and across levels. These epistemic levels were defined by discipline-specific geological constructs from descriptions of data, to identification of features, to relational aspects of features, to theoretically formulated assertions. This form of argumentation analysis allowed for assessment of each student's writing on normative grounds and for comparisons across students' papers. Results show promise for the argumentation model as a methodological tool. The examination of epistemic status of knowledge claims provided ways of distinguishing the extent to which students adhered to the genre conventions specified by the task, i.e., providing evidentiary support for their argument concerning the theory of plate tectonics with real earth data. We draw on the findings to discuss ways argumentation theory can contribute to reform in science education.

    Development of decade-long time series of global surface wind measurements for studies ofseasonal-to-interannual climate variability presents unique challenges for space- borne instrumentationbecause of the necessity to combine data sets of 3- to 5-year lifetimes. Before the first Special SensorMicrowave Imager (SSMI), which was launched on the Defence Meteorological Satellite Program(DMSP) F8 spacecraft in July 1987, stopped recording wind speed in December 1991, another SSMIwas launched on DMSP F10 in December 1991. Interpretation of the 1987 - 1993 composite timeseries is dependent upon the space and time characteristics of the differences between concurrent F8and F10 SSMI measurements. This paper emphasizes large geographical regions and 1-month timescale. The F8-F10 area-weighted difference between 60 degrees S and 60 degrees S during 305 daysof 1991 (-0.12 m s^(-1)) was comparable to the year-to-year wind speed variations during 1988-1991. The 10 degree-zonal averaged monthly mean F8-F10 difference was negative (positive) forwind speeds less (greater) than 7.9 m s^(-1), reaching - 0.43(0.32) m s^(-1) at 5(10) m s^(-1). The10 degree-zonal averaged monthly mean F8-F10 bias had considerable variations throughout the yearand between 60 degrees S - 60 degrees N, with the largest temporal variation (1.4 m s^(-1)) in the 50degrees - 60 degrees N region from February to April. The 1991 average value of the monthly meanroot-mean-square (rms) difference between F8 and F10 daily wind speeds in 10 degree-longitudinalbands was 2.0 m s^(-1) over 60 degrees S - 60 degrees N, the amplitude of the annual cycle of therms difference was largest in the northern hemisphere middle latitudes, and the rms difference wasrelated to the wind speed (e.g., at 6 and 10 m s^(-1), the rms difference was 1.7 and 2.7 m s^(-1),respectively). The relationship between monthly mean 1/3 degrees x 1/3 degrees F8-F10 SSMI windspeed differences and integrated water vapor and liquid water content in the atmosphere is discussed.

  6. Alaskan oceanography

    NASA Astrophysics Data System (ADS)

    Physical oceanographers, chemists, and biologists will soon begin studying the seas around northern Alaska as part of an international effort to learn how increased fishing, oil and gas drilling, and land-based farming will affect marine life. The $2.5 million National Science Foundation (NSF)- funded study, called ISHTAR (Inner Shelf Transfer and Recycling in the Bering and Chukchi Seas), will involve scientists from the United States, Belgium, and Denmark.According to NSF, previous studies suggest that, despite a short growing season, the seas around the Bering Strait produce more plant life than most marine areas of the world. However, the source of mineral nutrients for this plant life and its destination in the food web or organic sediment is not well understood. The researchers will trace nutrients from the Yukon River and the deeper waters of the Bering Sea to the continental shelves of the Bering and Chukchi seas in an attempt to better understand what happens to land and marine organic matter when it enters this continental shelf ecosystem.

  9. How imprinting centres work.

    PubMed

    Lewis, A; Reik, W

    2006-01-01

    Imprinted genes tend to be clustered in the genome. Most of these clusters have been found to be under the control of discrete DNA elements called imprinting centres (ICs) which are normally differentially methylated in the germline. ICs can regulate imprinted expression and epigenetic marks at many genes in the region, even those which lie several megabases away. Some of the molecular and cellular mechanisms by which ICs control other genes and regulatory regions in the cluster are becoming clear. One involves the insulation of genes on one side of the IC from enhancers on the other, mediated by the insulator protein CTCF and higher-order chromatin interactions. Another mechanism may involve non-coding RNAs that originate from the IC, targeting histone modifications to the surrounding genes. Given that several imprinting clusters contain CTCF dependent insulators and/or non-coding RNAs, it is likely that one or both of these two mechanisms regulate imprinting at many loci. Both mechanisms involve a variety of epigenetic marks including DNA methylation and histone modifications but the hierarchy of and interactions between these modifications are not yet understood. The challenge now is to establish a chain of developmental events beginning with differential methylation of an IC in the germline and ending with imprinting of many genes, often in a lineage dependent manner.

  16. The ARMADA Project: Bringing Oceanography and the Arctic to the Midwest

    NASA Astrophysics Data System (ADS)

    Pazol, J.

    2010-12-01

    In the fall of 2009, I spent 6 weeks aboard the Coast Guard Icebreaker Healy on a mapping expedition in the Arctic Ocean, through participation in the University of Rhode Island's ARMADA Project. Because I grew up in the Midwest, went to college here, and teach in the Chicago suburbs, I had limited first-hand experience in oceanography, as did most of my students. During my time aboard the ship, I primarily served as a member of the mapping team, collecting bathymetric and seismic data. My other science activities included aiding geologists and acoustic engineers in dredging projects and deployment of under-ice recording devices. I collected water data, sent off weather balloons, and assisted marine mammal observers. For the ARMADA Project I kept an on-line journal, which had a far-reaching impact. Students in many schools kept track of my activities and communicated with me via e-mail. Colleagues and friends shared the journal through other media, such as Facebook. Several of my entries were published in blogs belonging to NOAA and the USGS. I received a grant for renting a satellite phone, and through it was able to make "Live from the Arctic" phone calls. After introductory PowerPoints I communicated with more than 420 students in 5 schools in 3 states. When I returned, I made a series of presentations about the Arctic and my adventures to hundreds of people and was featured in an educational magazine with a circulation of more than 90,000. I also participated in an in-depth mentoring program with a new teacher to help her succeed during the first years of her career. The results: My students and I now have a direct connection to the Arctic and to the fields of oceanography, acoustic engineering, and geology. On their own initiative, students have developed individual projects exploring aspects of my research. They have attended presentations from the Extreme Ice Center and have become involved in drilling issues in the Chukchi Sea. A group of students is exploring the possibility of working with scientists from Scripps Institution of Oceanography to analyze the acoustic data. These are just some of the ways that a teacher's research experience can be effectively translated into the classroom setting.

    Oceanography is nowadays a fast-changing field. The scientific community is orienting towards the implementation of a growing array of satellite-borne or mobile and moored high-tech devices and sensors, while sending fewer scientists at sea to collect measurements, minimizing the expensive ship-time costs. In other words, oceanography is now moving from a platform-centric sensing system to a net-centric distributed sensing system. Integration with operational ocean models, providing the best estimate of the ocean state by means of data assimilation, is the step forward, with nowadays mature initiatives at global scale and at regional scale in the Mediterranean Sea. While the ocean still remains a complex system, largely undersampled, multiplatform-integration, improvements in tools capabilities and assimilation in models represents one way to reduce uncertainties in marine areas. In this context, and differently from mobile platforms (e.g, gliders, argos), fixed-point moorings nicely provide long term point wise time-series, but limited by a low vertical resolution. Technology is fast evolving towards the implementation of automatic profilers, which partially overcome this limitation. In June 2013 the Institute of Marine Sciences of the Italian National Research Council (CNR-ISMAR) started the test phase of one of the very few Mediterranean autonomous profiling systems installed in a open-sea mooring, transmitting, daily, hydrological vertical profiles in real time through satellite communication. The selected site was the Corsica Channel, a narrow passage between Corsica and Capraia islands, connecting the two main regions of the western Mediterranean: the Tyrrhenian and the Liguro-Provençal basins. The Corsica Channel represents a 'choke point' for the study of the dynamics and evolution of the western Mediterranean Sea. Previous studies in this passage indicate an annual and seasonal cycle with northward winter fluxes representing about the 60% of the total annual transport. In summer, excluding few cases of current inversions, exchanges between the two basins are mostly interrupted. Here the use of the new profiler is discussed. The profiling buoy system can be mounted at any level of a moored chain, which doesn't need any surficial support, allowing the flexibility to monitor discontinuities and sharp changes along selected depth ranges, at the same time, transmitting real-time data for best integration in modern operational oceanography networks.

    Tuna catches represent a major economic and food source in the Pacific Ocean, yet are highly variable. This variability in tuna catches remains poorly explained. The relationships between the distributions of tuna and their forage (micronekton) have been mostly derived from model estimates. Observations of micronekton and other mid-trophic level organisms, and their link to regional oceanography, however are scarce and constitute an important gap in our knowledge and understanding of the dynamics of pelagic ecosystems. To fill this gap, we conducted two multidisciplinary cruises (Nectalis1 and Nectalis2) in the New Caledonian Exclusive Economic Zone (EEZ) at the southeastern edge the Coral Sea, in 2011 to characterize the oceanography of the region during the cool (August) and the hot (December) seasons. The physical and biological environments were described by hydrology, nutrients and phytoplankton size structure and biomass. Zooplankton biomass was estimated from net sampling and acoustics and micronecton was estimated from net sampling, the SEAPODYM ecosystem model, a dedicated echosounder and non-dedicated acoustics. Results demonstrated that New Caledonia is located in an oligotrophic area characterized by low nutrient and low primary production which is dominated by a high percentage of picoplankton cyanobacteria Prochlorococcus (>90%). The area exhibits a large-scale north-south temperature and salinity gradient. The northern area is influenced by the equatorial Warm Pool and the South Pacific Convergence Zone and is characterized by higher temperature, lower salinity, lower primary production and micronekton biomass. The southern area is influenced by the Tasman Sea and is characterized by cooler temperature, higher salinity, higher primary production and micronekton biomass. The dynamic oceanography and the complex topography create a myriad of mesoscale features including eddies, inducing patchy structures in the ecosystem. During the cool season, a tight coupling existed between the ocean dynamics and primary production, while there was a stronger decoupling during the hot season. There was little difference in the composition of mid-trophic level organisms (zooplankton and micronekton) between the two seasons. This may be due to different turn-over times and delays in the transmission of primary production to upper trophic levels. Examination of various sampling gears for zooplankton and micronekton showed that net biomass estimates and acoustic-derived estimates compared reasonably well. Estimates of micronekton from net observations and the SEAPODYM model were in the same range. The non-dedicated acoustics adequately reproduced trends observed in zooplankton from nets, but the acoustics could not differentiate between zooplankton and micronekton and absolute biomasses could not be calculated. Understanding the impact of mesoscale features on higher trophic levels will require further investigation and patchiness induced by eddies raises the question of how to best sample highly dynamic areas via sea experiments.

    The CMCC Data Distribution Centre (DDC) is the primary entry point (web gateway) to the CMCC. It is a Data Grid Portal providing a ubiquitous and pervasive way to ease data publishing, climate metadata search, datasets discovery, metadata annotation, data access, data aggregation, sub-setting, etc. The grid portal security model includes the use of HTTPS protocol for secure communication with the client (based on X509v3 certificates that must be loaded into the browser) and secure cookies to establish and maintain user sessions. The CMCC DDC is now in a pre-production phase and it is currently used only by internal users (CMCC researchers and climate scientists). The most important component already available in the CMCC DDC is the Search Engine which allows users to perform, through web interfaces, distributed search and discovery activities by introducing one or more of the following search criteria: horizontal extent (which can be specified by interacting with a geographic map), vertical extent, temporal extent, keywords, topics, creation date, etc. By means of this page the user submits the first step of the query process on the metadata DB, then, she can choose one or more datasets retrieving and displaying the complete XML metadata description (from the browser). This way, the second step of the query process is carried out by accessing to a specific XML document of the metadata DB. Finally, through the web interface, the user can access to and download (partially or totally) the data stored on the storage device accessing to OPeNDAP servers and to other available grid storage interfaces. Requests concerning datasets stored in deep storage will be served asynchronously.

    The particular program, the Gulf of Mexico Physical Oceanography Program, has two primary goals: (1) develop a better understanding and description of conditions and processes governing Gulf circulation; and, (2) establish a data base that could be used as initial and boundary conditions by a companion MMS-funded numerical circulation-modeling program. The program participants undertook the following primary scientific efforts during Program Year 4: (1) kinematic and hydrographic characterizations of Loop Current boundary features, e.g., waves, filaments, or perturbations; (2) comparative kinematics and dynamics of the Loop Current and a Loop Current eddy as indicated by drifting buoy trajectories; and (3) further discrimination and characterization of West Florida Shelf circulation patterns, e.g., inertial currents, wind, and Loop Current forced currents.

    The proper mathematical limit of a hyperbolic system with multiple time scales, the reduced system, is a system that contains no high-frequency motions and is well posed if suitable boundary conditions are chosen for the initial-boundary value problem. The composite grid method, a robust and efficient grid-generation technique that smoothly and accurately treats general irregular boundaries, is used to approximate the two-dimensional version of the reduced system for oceanography on irregular ocean basins. A change-of-variable technique that substantially increases the accuracy of the model and a method for efficiently solving the elliptic equation for the geopotential are discussed. Numerical results are presented for circular and kidney-shaped basins by using a set of analytic solutions constructed in this paper.

    2002-05-01

    At the turn of the Twentieth Century, the Coast and Geodetic Survey was one of the major physical science agencies in the United States Federal Government. Nautical charting, with the attendant generation of large ocean-depth data holdings, required expertise in navigation techniques, physical oceanography, and geodetic surveying. This expertise was coupled with the development of systems and methods that led to many serendipitous discoveries by the Coast and Geodetic Survey or by its collaboration with other institutions and individuals. Many of these fundamental discoveries were built upon by the American ocean science community in developing modern earth science theories as well as in improving techniques and methods of ocean exploration. This work continues today through many offices in the National Oceanic and Atmospheric Administration that are direct descendants of the old Coast and Geodetic Survey.

    The Distributed Active Archive Center (DAAC) at the Jet Propulsion Laboratory will support scientists specializing in physical oceanography and air-sea interaction. As part of the NASA Earth Observing System Data and Information System Version 0 the DAAC will build on existing capabilities to provide services for data product generation, archiving, distribution and management of information about data. To meet scientist's immediate needs for data, existing data sets from missions such as Seasat, Geosat, the NOAA series of satellites and the Global Positioning Satellite system will be distributed to investigators upon request. In 1992, ocean topography, wave and surface roughness data from the Topex/Poseidon radar altimeter mission will be archived and distributed. New data products will be derived from Topex/Poseidon and other sensor systems based on recommendations of the science community. In 1995, ocean wind field measurements from the NASA Scatterometer will be supported by the DAAC.

    2013-12-01

    A recent workshop sponsored by SERC-On the Cutting Edge brought together science educators from a range of schools across the country to discuss new approaches in teaching oceanography. In discussing student interest in our classes, we were struck by the fact that students are drawn to emotional or controversial topics such as whale hunting and tsunami hazard and that these kinds of topics are a great vehicle for introducing more complex concepts such as wave propagation, ocean upwelling and marine chemistry. Thus, we have developed an approach to introductory oceanography that presents students with real-world issues in the ocean sciences and requires them to explore the science behind them in order to improve overall ocean science literacy among non-majors and majors at 2 and 4 year colleges. We have designed a project-based curriculum built around topics that include, but are not limited to: tsunami hazard, whale migration, ocean fertilization, ocean territorial claims, rapid climate change, the pacific trash patch, overfishing, and ocean acidification. Each case study or project consists of three weeks of class time and is structured around three elements: 1) a media analysis; 2) the role of ocean science in addressing the issue; 3) human impact/response. Content resources range from textbook readings, popular or current print news, documentary film and television, and data available on the world wide web from a range of sources. We employ a variety of formative assessments for each case study in order to monitor student access and understanding of content and include a significant component of in-class student discussion and brainstorming guided by faculty input to develop the case study. Each study culminates in summative assessments ranging from exams to student posters to presentations, depending on the class size and environment. We envision this approach for a range of classroom environments including large group face-to-face instruction as well as hybrid and fully online courses.

  6. A permanent presence in the global ocean: A new approach to oceanography

    Oceanography has been dominated for at least two centuries by an expeditionary approach and examples include the voyage of the Beagle in 1831-1836 and the Challenger Expedition in 1872 - 1876. In the U.S., the capabilities for expeditionary research were greatly amplified during and especially following WW II. Today the U.S. alone has established a research fleet of 28 vessels organized through UNOLS. While experimental oceanography has made enormous contributions over the decades and centuries, this approach has not been well-suited to investigating processes in which transients are important. The Dynamics of Earth and Ocean Systems (DEOS) program was developed in 1997 to promote the idea of making long-term observations in the oceans - to establish a long-term presence in the oceans. DEOS, recently reconfigured under sponsorship by the Consortium for Ocean Research and Education (CORE), advocates the collection of long-term time-series data with the recognition that this is the only viable approach to observe transients and changes and to enhance the signal-to-noise ratio of weak signals. We believe that moored ocean buoys are a technically feasible approach for making sustained time series observations in the oceans and will be an important component of any long-term ocean observing system. Because of the broad spectrum of scientific needs identified during planning, it is clear that there is no single buoy or mooring design that will meet all of these needs while at the same time minimizing costs. Both the U.S. and Britain (B-DEOS) have completed design studies for these buoys and we will present these alternatives in light of realistic ocean environments.

    To detect and predict changes in coastal and open-ocean ecosystems is a huge requirement monitoring in detail and real-time their baseline physical, geological and chemical properties. In these regards and following the trends and general objectives established by GOOS (Global Ocean Observing System) through its coastal ecosystems module COOP (Coastal Ocean Observations Panel), the present paper describes the design, first development stages and some derived results of a monitoring network, named Red ACOMAR Canarias (Red de Alerta, Control y Observación MARina de Canarias, in English: Network for Marine Surveillance, Control and Observation in the Canaries) developed in the Macaronesia region.Since 1999, the Red ACOMAR is based in a core project supported throughout several proposals at the same time, developed in the coastal and open-ocean areas around the Canary Islands archipelago. The network integrates a wide group of devices and monitoring systems (moored and drifting buoys, gliders, remote sensing, turtles, land based meteorological stations, research vessels,…) working in real-time. The network has a control centre that manages communications and data processing, and provides real-time information in a functional form to end-users from socio-economic important sectors, which make an exhaustive use of the coastal area in the region. The access to the information by the users is done through a web site. The Red ACOMAR is nowadays directly linked with other similar proposals existing in the area, mainly from scientist groups in Azores and Madeira archipelagos, as well as from other European countries, working all together with the aim to bring out a regional contribution in Operational Oceanography to the end-users requirements.

    Comparative quality analyses of rehabilitation centres are required by the legislators and are the focus of the external Quality Assurance plans presently implemented. However, they are also highly relevant for internal Quality Management models (e.g. for the result criteria of the EFQM model). To control for confounders of rehabilitation success that cannot be influenced by the rehabilitation centre (e.g. age, co-morbidity), and thus to permit fair comparisons of clinics, regression analysis risk adjustment procedures are primarily used in the literature. The present paper explains the use of so-called Hierarchical Linear Models (HLMs) using example of data of N = 2.044 patients undergoing rehabilitation following hip and knee operations from the Quality Assurance programme of the statutory health insurance funds (QA-Reha-procedure). This procedure has the advantages of: a) taking into account the multi-level structure of the comparison problem; b) permitting the inclusion of predictors at the rehabilitation centre level; and c) permitting the modelling of variation in regression coefficients over the centres. The data presented show that the differences in achieved rehabilitation outcome among the rehabilitation centres - after control of the confounders by means of HLMs tend to be slight. In addition to patient-related predictors of rehabilitation outcome (baseline somatic, functional, psychosocial status, co-morbidity, rehabilitation motivation, gender, age), the mean functional disability of the patients in the centre is shown to be a confounder at the clinic level. In this respect, a centre that has little experience with severely affected rehabilitation patients achieves on average lesser effects on somatic, functional, and psychosocial levels. PMID:15646728

    The overall objectives of EMODNET - physical parameters is to provide access to archived and real-time data on physical conditions in Europe's seas and oceans and to determine how well the data meet the needs of users. In particular it will contribute towards the definition of an operational European Marine Observation and Data Network (EMODnet) and contribute to developing the definition of the Global Monitoring for Environment and Security (GMES) marine core service. Access to data and metadata will consider measurements from fixed stations that will cover at least: 1. wave height and period; 2. temperature of the water column; 3. wind speed and direction; 4. salinity of the water column; 5. horizontal velocity of the water column ; 6. light attenuation; 7. sea level. A first running prototype of the portal active from the end of 2011, the final release of the EMODnet PP is due by half June 2012. Then there are 6 months for testing and users' feedback acquisition and management. The project finishes 16th December 2013 after one year of maintenance. Compliance with INSPIRE framework and temporal and geographical data coverage are ensured under the requirements contained in the several Commission Regulations issued from 2008 until 2010. The metadata are based upon the ISO 19115 standard and are compliant with the INSPIRE directive and regulations. This assures also a minimum metadata content in both systems that will facilitate the setting up of a portal that can provide information on data and access to them, depending on the internal data policy of potential contributors. Data coverage: There are three pillars sustaining EMODnet PP: EuroGOOS ROOSs (the EuroGOOS regional Operational Systems), MyOcean and SeaDataNet. MyOcean and EuroGOOS have agreed in EuroGOOS general assemblies (2008-2009-2010) to share their efforts to set up a common infrastructure for real-time data integration for operational oceanography needs extending the global and regional portals set up by MyOcean to handle additional variables and observation providers. SeaDataNet is a Pan-European infrastructure for oceans and marine data management, that provides access to archived data residing in distributed information systems. EMODNet Physics held three workshops with institutions working in operational data collection in the Baltin, North Sea, East Atlantic, Mediterranean and Black Sea. They allowed to list most of the existing fixed stations in the seas of European interest. The workshops and the follow up are constructing a common collaborative framework within EuroGOOS ROOSs. Behind the ROOSs there is a wide number of institutions, scientists and technicians, whose participation to EMODnet PP will be acknowledged and made visible through the web pages, newsletters, and EuroGOOS publications. This common collaborative framework is producing an important network of data centres that can support GMES for the years to come.

    With over half of the current earth and space science workforce expected to retire within the next 15 years, NASA has responded by cultivating young minds through programs such as the Student Airborne Research Program (SARP). SARP is a competitive internship that introduces upper-level undergraduates and early graduate students to Earth System Science research and NASA's Airborne Science Program. The program serves as a model for recruitment of very high caliber students into the scientific workforce. Its uniqueness derives from total vertical integration of hands-on experience at every stage of airborne science: aircraft instrumentation, flight planning, mission participation, field-work, analysis, and reporting of results in a competitive environment. At the conclusion of the program, students presented their work to NASA administrators, faculty, mentors, and the other participants with the incentive of being selected as best talk and earning a trip to the fall AGU meeting to present their work at the NASA booth. We hope lessons learned can inform the decisions of scientists at the highest levels seeking to broaden the appeal of research. In 2011, SARP was divided into three disciplinary themes: Oceanography, Land Use, and Atmospheric Chemistry. Each research group was mentored by an upper-level graduate student who was supervised by an expert faculty member. A coordinator managed the program and was supervised by a senior research scientist/administrator. The program is a model of knowledge transfer among the several levels of research: agency administration to the program coordinator, established scientific experts to the research mentors, and the research mentors to the pre-career student participants. The outcomes from this program include mission planning and institutional knowledge transfer from administrators and expert scientists to the coordinator and research mentors; personnel and project management from the coordinator and expert scientists to the research mentors; and scholarship and training in specific analytical techniques for Earth Science research from the mentors to the student participants. Across every level, the program allowed for networking and career advice to help students gain entry to future job or graduate school opportunities. This poster details "engaging the next generation" by highlighting specific research questions proposed and developed by the students in the Oceanography group.

    Devenny, Bob; Duffy, Kathleen

    Person-centred health and person-centred care have gained prominence across the UK following the publication of reports on public inquiries exploring failings in care. Self-awareness and participation in reflective practice are recognised as vital to supporting the person-centred agenda. This article presents an education framework for reflective practice, developed and used in one NHS board in Scotland, and based on the tenets of the clinical pastoral education movement. Providing an insight into the usefulness of a spiritual component in the reflective process, the framework provides an opportunity for nurses and other healthcare professionals to examine the spiritual dimensions of patient encounters, their own values and beliefs, and the effect these may have on their practice.

    1989-01-01

    The ecosystem of the northern Bering-Sea shelf was studied using data from the NOAA Very High Resolution Radiometer and AVHRR and the Landsat MSS and Thematic Mapper (TM) in conjunction with shipboard measurements. Emphasis was placed on the influence of the Yukon River on this inner shelf environment and on the evaluation of the utility of the new Landsat TM data for oceanography. It was found that the patterns of water mass distribution obtained from satellite images agreed reasonably well with the areal patterns of temperature, salinity, and phytoplankton distributions. The AVHRR, MSS, and TM data show that the Yukon-River discharge is warmer and more turbid than the surrounding coastal water that originates to the south; thus, the Yukon water contributes to the higher temperatures and lower transmissivity of the coastal water. The high resolution of the TM thermal IR band made it possible to observe complex patterns and structures in the surface water that could not be resolved on previous data sets.

    The ERTS-1 color composite picture of the Vancouver-Victoria region illustrates the value of ERTS data for coastal oceanography. The water of the Fraser River plume which is so clearly visible in the center of the scene has been of interest to oceanographers on the west coast of Canada for a long time as an easily visible tracer of surface water circulation in the strait of Georgia. Maps of the plume at different states of the tide and with different river flow and weather were compiled from oblique aerial photographs in 1950 and used in the siting of sewage and other outfalls in the Vancouver area. More recently high level aerial photomosaics have been used to map the plume area, but the plume can spread over distances of 30 to 40 miles and many photographs, with the uneven illumination inherent in wide angle coverage, are needed for the mosaic. The ERTS satellite gives the first complete view of the plume area. Electronic enhancement of the images shows that the satellite's narrow angle coverage allows very weak surface turbidity features to be made visible to give information on surface currents over a wide area.

  16. The application of standard definitions of sound to the fields of underwater acoustics and acoustical oceanography

    Carey, William M.

    2001-05-01

    Recent societal concerns have focused attention on the use of sound as a probe to investigate the oceans and its use in naval sonar applications. The concern is the impact the use of sound may have on marine mammals and fishes. The focus has changed the fields of acoustical oceanography (AO) and underwater acoustics (UW) because of the requirement to communicate between disciplines. Multiple National Research Council publications, Dept. of Navy reports, and several monographs have been written on this subject, and each reveals the importance as well as the misapplication of ASA standards. The ANSI-ASA standards are comprehensive, however not widely applied. The clear definition of standards and recommendations of their use is needed for both scientists and government agencies. Traditionally the U.S. Navy has been responsible for UW standards and calibration; the ANSI-ASA standards have been essential. However, recent changes in the Navy and its laboratory structure may necessitate a more formal recognition of ANSI-ASA standards and perhaps incorporation of UW-AO in the Bureau of Standards. A separate standard for acoustical terminology, reference levels, and notation used in the UW-AO is required. Since the problem is global, a standard should be compatible and cross referenced with the International Standard (CEI/IEC 27-3).

    2008-07-01

    This contribution describes the procedure used during the Prestige oil-spillage event, by means of an Operational Oceanography System, and the behaviour of the present prediction tools (hydrodynamic and dispersion models) applied to it. The accuracy of these tools is estimated by a reanalysis of field data transmitted by a sea surface drifting buoy, released at the time of the oil spill. The numerical models applied were the Regional Ocean Modeling System (ROMS), fed by the available six-hourly NCEP atmospheric information, together with a Lagrangian Particle-Tracking Model (LPTM). ROMS has been used to estimate the current fields for the Bay of Biscay, whilst the LPTM has provided the oil spill trajectories. The results demonstrate that the accuracy of the numerical models depends upon the quality of the meteorological input data. In this case, the current fields at the sea surface, derived by ROMS, have been underestimated by the wind fields of the NCEP reanalysis data. An efficient calibration of these wind fields, with data provided by the Gascony buoy (fixed oceanic and atmospheric station), achieves more realistic looking results; this is reflected in the comparison between the buoy trajectory predicted numerically and the tracked movements of the drifting buoy.

  18. Toxic red tides and harmful algal blooms: A practical challenge in coastal oceanography

    Anderson, Donald M.

    1995-07-01

    The debate over the relative value of practical or applied versus fundamental research has heated up considerably in recent years, and oceanography has not been spared this re-evaluation of science funding policy. Some federal agencies with marine interests have always focused their resources on practical problems, but those with a traditional commitment to basic research such as the National Science Foundation have increasingly had to fight to maintain their freedom to fund quality science without regard to practical or commercial applications. Within this context, it is instructive to highlight the extent to which certain scientific programs can satisfy both sides of this policy dilemma—i.e. address important societal issues through advances in fundamental or basic research. One clear oceanographic example of such a program involves the phenomena called "red tides" or "harmful algal blooms". This paper describes the nature and extent of the problems caused by these outbreaks, emphasizing the alarming expansion in their incidence and their impacts in recent years, both in the U.S. and worldwide. The objective is to highlight fundamental physical, biological, and chemical oceanographic question that must be addressed if we are to achieve the practical goal of scientifically based management of fisheries resources, public health, and ecosystem health in regions threatened by toxic and harmful algae.

    On 19th November 2002, the oil tanker Prestige (containing 77,000 tonnes of heavy fuel no. 2 (M100)) sank in 3500 m of water, off the coast of northwestern Spain. Intermittent discharge of oil from the stricken tanker, combined with large-scale sea surface dispersion, created a tracking and recovery problem. Initially, conventional oil recovery approaches were adopted, close to the wreck. With time and distance from the source, the oil dispersed dramatically and became less viscous. Consequently, a unique monitoring, prediction and data dissemination system was established, based upon the principles of 'operational oceanography'; this utilised in situ tracked buoys and numerical (spill trajectory) modelling outputs, in combination with remote sensing (satellite sensors and visual observation). Overall, wind effects on the surface waters were found to be the most important mechanism controlling the smaller oil slick movements. The recovery operation involved up to 180 fishing boats, 9-30 m in length. Such labour-intensive recovery of the oil (21,000 tonnes, representing an unprecedented ratio of 6.6 tonnes at sea, per tonne recovered on land) continued over a 10 month period. The overall recovery at sea, by the fishing vessels, represented 63% of the total oil recovered at sea; this compares to only 37% recovered by specialised 'counter- pollution' vessels. PMID:16769415

    We developed advanced communications and networking capability and satellite reception systems for Earth science to improve the ability of scientists at Scripps Institution of Oceanography (SIO) to conduct interdisciplinary research. With matching funds from the SIO Director's office we implemented a "virtual center" utilizing modern networking hardware and software to enhance access for researchers and students to unique satellite and in situ data sets. The center provides facilities and data access to graduate students as well as research scientists at SIO, and outside SIO. Our private sector partners installed and testes and advanced X-band data acquisition system for satellite data capture relevant for Earth science research and applications. Some of the commercial applications of these partners have been developed (or are under development) with NASA SBIR resources. The X-band system collected RADARSAT, ERS-2 and MODIS imagery. Perhaps most importantly, this COE brought together - for the first time - an interdisciplinary team of SIO scientists with interests in Earth remote sensing. The collaboration extended beyond our infrastructure and research accomplishments leading to a dialog that resulted in a report with strong recommendations to the SIO community for enhancing satellite remote sensing at SIO.

    Within the last year scientists and educators at the Scripps Institution of Oceanography (SIO), the Birch Aquarium at Scripps and San Diego State University have collaborated with education specialists to develop 3D interactive graphic teaching modules for use in the classroom and in teacher workshops at the SIO Visualization center (http://siovizcenter.ucsd.edu). The unique aspect of the SIO Visualization center is that the center is designed around a 120 degree curved Panoram floor-to-ceiling screen (8'6" by 28'4") that immerses viewers in a virtual environment. The center is powered by an SGI 3400 Onyx computer that is more powerful, by an order of magnitude in both speed and memory, than typical base systems currently used for education and outreach presentations. This technology allows us to display multiple 3D data layers (e.g., seismicity, high resolution topography, seismic reflectivity, draped interferometric synthetic aperture radar (InSAR) images, etc.) simultaneously, render them in 3D stereo, and take a virtual flight through the data as dictated on the spot by the user. This system can also render snapshots, images and movies that are too big for other systems, and then export smaller size end-products to more commonly used computer systems. Since early 2002, we have explored various ways to provide informal education and outreach focusing on current research presented directly by the researchers doing the work. The Center currently provides a centerpiece for instruction on southern California seismology for K-12 students and teachers for various Scripps education endeavors. Future plans are in place to use the Visualization Center at Scripps for extended K-12 and college educational programs. In particular, we will be identifying K-12 curriculum needs, assisting with teacher education, developing assessments of our programs and products, producing web-accessible teaching modules and facilitating the development of appropriate teaching tools to be used directly by classroom teachers.

    In certain parts of the Canadian Archipelago, small localized areas of water remain ice free throughout the winter, despite the extreme temperature differences between the atmosphere and the ocean surface. One such area, close to Dundas Island, has been studied in detail, both from the point of view of the atamospheric/oceanic heat exchange over the open water and its local geographic and oceanographic context. The paper describes the oceanography of the area and local weather and tidal flow conditions. A significant feature of the oceanographic records is a strong modulation of near-surface ocean temperature at tidal frequencies involving temperature differences as great as 0.2 /sup 0/C within a single tidal cycle. For the most part, the surface waters are 0.1/sup 0/ to 0.2 /sup 0/C above freezing. The presence of this relatively warm surface water is thought to be due to upward mixing occasioned by fast tidal flows across the shallow sill connecting Dundas and Devon islands. Historical records of water properties in the Sverdrup Basin lying to the north of the polynya area show temperatures substantially above freezing point at depths of 50 m and below. This readily accessible body of warm water is thought to be the source of the sensible heat required for the existence of the polynya. This is supported by existing current measurements which suggest a mean southerly transport in the channels leading into and out of the region of the polynya site. A tentative application of the atmospheric heat flux measurements to the whole Dundas Island--Bailey Hamilton Island area suggests that sufficient heat may be lost to affect significantly the water column further south in Crozier Strait and Wellington Channel. The limited information available shows the more southerly waters of these passages to be relatively well mixed and cooled relative to the water of the Sverdrup Basin, just to the north of the Dundas polynya area.

    General education courses at many universities are required to demonstrate specific student learning outcomes and methodologies of learning assessment that can be measure the success, or lack thereof, of meeting these outcomes. A primary learning outcome of the SJSU general education program is to have students apply a scientific approach to problems of the earth and environment. This requirement can be challenging in high enrollment classes offered at universities without the resources of graduate teaching assistantships. In order to meet this outcome through an active learning environment, we have redesigned a web-based oceanography course, primarily for non-science majors, that has students assume the role of shipboard scientists on a number of ocean-going virtual research experiences. One activity has students participate on a virtual research voyage based on a multi-beam sonar study of the central San Francisco Bay described in USGS Circular 1259 by Chin et al (2004). Students carry out the duties of virtual shipboard scientists, including pre- and post-cruise scientific meetings, sonar data acquisition, processing and visualization, and interpretation of the seafloor mapping data using a combination of scientific visualizations, animations, and audio and video segments. While on the voyage, students are required to: (1) determine the navigational hazards posed by three submerged rocks near the main shipping lane in the bay, (2) assess the long-term viability of a disposal site for mud dredged from the bay, and (3) generate a sediment characteristics map of the bay floor that can be used as a basis for future studies of contaminant transport. Upon completion of the voyage students are required to write an abstract describing their research for publication in the proceedings volume of a virtual scientific conference in the form of an essay question on the mid-term exam. Based on the work of over 200 students, this question has received the highest score of four essay questions on the exam during the past two terms.

    The scattering cross-section sigma(s) of a gas bubble of equilibrium radius R(0) in liquid can be written in the form sigma(s)=4piR(0) (2)[(omega(1) (2)omega(2)-1)(2)+delta(2)], where omega is the excitation frequency, omega(1) is the resonance frequency, and delta is a frequency-dependent dimensionless damping coefficient. A persistent discrepancy in the frequency dependence of the contribution to delta from radiation damping, denoted delta(rad), is identified and resolved, as follows. Wildt's [Physics of Sound in the Sea (Washington, DC, 1946), Chap. 28] pioneering derivation predicts a linear dependence of delta(rad) on frequency, a result which Medwin [Ultrasonics 15, 7-13 (1977)] reproduces using a different method. Weston [Underwater Acoustics, NATO Advanced Study Institute Series Vol. II, 55-88 (1967)], using ostensibly the same method as Wildt, predicts the opposite relationship, i.e., that delta(rad) is inversely proportional to frequency. Weston's version of the derivation of the scattering cross-section is shown here to be the correct one, thus resolving the discrepancy. Further, a correction to Weston's model is derived that amounts to a shift in the resonance frequency. A new, corrected, expression for the extinction cross-section is also derived. The magnitudes of the corrections are illustrated using examples from oceanography, volcanology, planetary acoustics, neutron spallation, and biomedical ultrasound. The corrections become significant when the bulk modulus of the gas is not negligible relative to that of the surrounding liquid. PMID:19894796

    The BCO-DMO (http://www.bco-dmo.org) was created to serve PIs funded by the NSF Biological and Chemical Oceanography Sections as a facility where marine biogeochemical and ecological data and information developed in the course of scientific research can easily be disseminated, protected, and stored on short and intermediate time-frames. The Data Management Office also strives to provide research scientists and others with the tools and systems necessary to work with marine biogeochemical and ecological data from heterogeneous sources with increased efficacy. To accomplish this, two data management offices (former- U.S. JGOFS and U.S. GLOBEC) have been united and enhanced to provide a venue for contribution of electronic data/metadata and other information for open distribution via the World Wide Web. The JGOFS/GLOBEC Client/Server distributed data management system software is used to serve data and information to every investigator, regardless of computing platform. In addition, Web services are provided for data discovery, and development has begun on a machine-to-machine application programming interface (API) to allow interoperability between Web-based data systems. The BCO-DMO will manage existing and new data sets from individual scientific investigators, collaborative groups of investigators, and data management offices of larger multi-institutional projects via any standard Web browser. The office will work with principal investigators on data quality control; maintain an inventory and program thesaurus of strictly defined field names; generate metadata (e.g. Directory Interchange Format (DIF) ) records required by Federal agencies; ensure submission of data to national data centers; support and encourage data synthesis by providing new, online, Web-based display tools; facilitate interoperability among different data portals; and facilitate regional, national, and international data and information exchange.

  9. Merging observations with numerical models in oceanography: some approaches and experiences gained within ECCO (Invited)

    Heimbach, P.

    2009-12-01

    The problem of extracting information of the state of the polar ice sheets and their evolution through time from sparse observations and with poorly known surface and basal boundary conditions is not unlike the one faced by oceanographers who seek to estimate the global time-varying ocean circulation. Through concerted sea-going campaigns during the World Ocean Circulation Experiment (WOCE), and through the advent of satellite remote sensing dedicated to oceanography the oceanographic community had for the first time nearly global, time-continuous, but diverse, data sets as well as rapidly improving general circulation models (GCMs). Observations remain mostly limited to the near-surface though, cannot be readily compared with each other (altimetry and gravity, for example, measure very different properties and scales), and a quantitative link to the very limited set of in-situ observations, particularly at depth, is difficult. The need to fully exploit the data and models for the purpose of describing and understanding the global ocean circulation and its variability led the establishment of the consortium Estimating the Ocean Circulation and Climate (ECCO). ECCO has sought three-dimensional time-evolving oceanographic estimates which were fully consistent with the available observations, and with the particular GCM being used (primarily the MITgcm), in turn subject to central conservation principles (volume, energy, fresh water, etc.) and, to the degree the GCM was dynamically consistent, with time evolution not subject to artificial jumps or the injection of unphysical sources and sinks e.g. of heat. The science goals of ECCO include the understanding and explanation of the transfers of enthalpy and fresh water to and from the atmosphere and sea ice fields, and so consistency with basic conservation laws is essential. An estimation method which fulfills this requirement, pursued initially by the MIT/SIO and recently by the MIT/AER groups is the adjoint or Lagrange Multiplier method (LMM). The glaciological community has gained familiarity with this approach through the introdcution of control methods by MacAyeal (1992) in the context of inferring ice stream basal boundary conditions from observations. This presentation provides an overview of some of the challenges faced within ECCO, including the development of the required adjoint model of the MITgcm, the choice of control variables, the the role of prior uncertainties, the diverse mix of observations. As ECCO moves from a purely oceanographic to a coupled effort, initially including the sea-ice state, efforts will also be required to improve the connection between the ocean's interior and the margins, in particular in the vicinity of the marine ice shelves.

  10. Transition of R&D into Operations at Fleet Numerical Meteorology and Oceanography Center

    The U.S. Navy's Fleet Numerical Meteorology and Oceanography Center (FNMOC) plays a significant role in the National capability for operational weather and ocean prediction through its operation of sophisticated global and regional meteorological and oceanographic models, extending from the top of the atmosphere to the bottom of the ocean. FNMOC uniquely satisfies the military's requirement for a global operational weather prediction capability based on software certified to DoD Information Assurance standards and operated in a secure classified computer environment protected from outside intrusion by DoD certified firewalls. FNMOC operates around-the-clock, 365 days per year and distributes products to military and civilian users around the world, both ashore and afloat, through a variety of means. FNMOC's customers include all branches of the Department of Defense, other government organizations such as the National Weather Service, private companies, a number of colleges and universities, and the general public. FNMOC employs three primary models, the Navy Operational Global Atmospheric Prediction System (NOGAPS), the Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS), and the WaveWatch III model (WW3), along with a number of specialized models and related applications. NOGAPS is a global weather model, driving nearly all other FNMOC models and applications in some fashion. COAMPS is a high- resolution regional model that has proved to be particularly valuable for forecasting weather and ocean conditions in highly complex coastal areas. WW3 is a state-of-the-art ocean wave model that is employed both globally and regionally in support of a wide variety of naval operations. Other models support and supplement the main models with predictions of ocean thermal structure, ocean currents, sea-ice characteristics, and other data. Fleet Numerical operates at the leading edge of science and technology, and benefits greatly from collocation with its supporting R&D activity, the Marine Meteorology Division of the Naval Research Laboratory (NRL Code 7500). NRL Code 7500 is a world-class research organization, with focus on weather-related support for the warfighter. Fleet Numerical and NRL Code 7500 share space, data, software and computer systems, and together represent one of the largest concentrations of weather-related intellectual capital in the nation. As documented, for example, by the Board on Atmospheric Sciences and Climate (BASC) of the National Research Council, investment in R&D is crucial for maintaining state-of-the-art operational Numerical Weather Prediction (NWP) capabilities (see BASC, 1998). And collocation and close cooperation between research and operations, such as exists between NRL Code 7500 and Fleet Numerical, is the optimum arrangement for transitioning R&D quickly and cost-effectively into new and improved operational weather prediction capabilities.

  11. Oceanography in Second Life: Use of a Virtual Reality to Enhance Undergraduate Education in Marine Science

    Shipboard research is a fundamental part of oceanography, but has numerous legal and practical constraints virtually eliminate it as a regular part of large-enrollment programs in marine science. The cost of a properly equipped research vessel alone can prevent student access. While much can be learned by active exploration of archived data by students, the limitations placed on real oceanographic programs by distance, vessel speed, and time are difficult to reproduce in exercises. Pre-cruise planning and collaboration between investigators are likewise a challenge to incorporate. We have used design students in the College of Liberal Arts to construct a oceanographic expedition in Second Life for use in a marine science course (Fall 2009). Second Life is a highly collaborative environment with a variety of tools that allow users to create their own environment and interact with it. Second LIfe is free, highly portable, and inherently amenable to distance or remote teaching. In our application, the research vessel exists as an moving platform with sampling abilities. Software code queries an external MySQL database that contains information from the World Ocean Atlas for the entire ocean, and returns strings of data from standard depths. Students must plan the cruise track to test hypothesis about the ocean, collaborate with other teams to develop the big picture and use standard oceanographic software (Ocean Data Viewer; ODV) to analyze the data. Access to the entire database in ODV then allows comparison to the actual properties and distributions. The effectiveness of this approach is being evaluated by a pre- and post-class surveys and post semester focus group interviews. Similar surveys of the design students that created the environment noted that use of Second Life created a learning experience that was both more immersive and process oriented than traditional college courses. Initial impressions in the marine science class indicate that the strong social networking presence captures these digital native undergraduates rapidly, and that this is a strong positive motivation for working on assigned class activities in Second Life.

  12. Extracting physical parameters from marine seismic data: New methods in seismic oceanography and velocity inversion

    NASA Astrophysics Data System (ADS)

    Fortin, Will F. J.

    The utility and meaning of a geophysical dataset is dependent on good interpretation informed by high-quality data, processing, and attribute examination via technical methodologies. Active source marine seismic reflection data contains a great deal of information in the location, phase, and amplitude of both pre- and post-stack seismic reflections. Using pre- and post-stack data, this work has extracted useful information from marine reflection seismic data in novel ways in both the oceanic water column and the sub-seafloor geology. In chapter 1 we develop a new method for estimating oceanic turbulence from a seismic image. This method is tested on synthetic seismic data to show the method's ability to accurately recover both distribution and levels of turbulent diffusivity. Then we apply the method to real data offshore Costa Rica where we observe lee waves. Our results find elevated diffusivities near the seafloor as well as above the lee waves five times greater than surrounding waters and 50 times greater than open ocean diffusivities. Chapter 2 investigates subsurface geology in the Cascadia Subduction Zone and outlines a workflow for using pre-stack waveform inversion to produce highly detailed velocity models and seismic images. Using a newly developed inversion code, we achieve better imaging results as compared to the product of a standard, user-intensive method for building a velocity model. Our results image the subduction interface ~30 km farther landward than previous work and better images faults and sedimentary structures above the oceanic plate as well as in the accretionary prism. The resultant velocity model is highly detailed, inverted every 6.25 m with ~20 m vertical resolution, and will be used to examine the role of fluids in the subduction system. These results help us to better understand the natural hazards risks associated with the Cascadia Subduction Zone. Chapter 3 returns to seismic oceanography and examines the dynamics of nonlinear internal wave pulses in the South China Sea. Coupling observations from the seismic images with turbulent patterns, we find no evidence for hydraulic jumps in the Luzon passage. Our data suggests geometric resonance may be the underlying physics behind large amplitude nonlinear internal wave pulses seen in the region. We find increased levels of turbulent diffusivity in deep water below 1000 m, associated with internal tide pulses, and near the steep slopes of both the Heng-Chun and Lan-Yu ridges.

  13. Designing and Implementing Service Learning Projects in an Introductory Oceanography Course Using the ``8-Block Model''

    NASA Astrophysics Data System (ADS)

    Laine, E. P.; Field, C.

    2010-12-01

    The Campus Compact for New Hampshire (Gordon, 2003) introduced a practical model for designing service-learning exercises or components for new or existing courses. They divided the design and implementation process into eight concrete areas, the “8-Block Model”. Their goal was to demystify the design process of service learning courses by breaking it down into interconnected components. These components include: project design, community partner relations, the problem statement, building community in the classroom, building student capacity, project management, assessment of learning, and reflection and connections. The project design component of the “8-Block Model” asks that the service performed be consistent with the learning goals of the course. For science courses students carry out their work as a way of learning science and the process of science, not solely for the sake of service. Their work supports the goals of a community partner and the community partner poses research problems for the class in a letter on their letterhead. Linking student work to important problems in the community effectively engages students and encourages them to work at more sophisticated levels than usually seen in introductory science classes. Using team-building techniques, the classroom becomes a safe, secure learning environment that encourages sharing and experimentation. Targeted lectures, labs, and demonstrations build the capacity of students to do their research. Behind the scenes project management ensures student success. Learning is assessed using a variety of tools, including graded classroom presentations, poster sessions, and presentations and reports to community partners. Finally, students reflect upon their work and make connections between their research and its importance to the well being of the community. Over the past 10 years, we have used this approach to design and continually modify an introductory oceanography course for majors and non-majors. The goal was to provide students with an opportunity to do authentic research on water quality and marine resource issues in local coastal embayments. Student research supported several community organizations, most notably the Friends of Casco Bay, an NGO interested in improving the water quality in Casco Bay. This research helped the students to reach some of the learning goals for the course including an understanding of tides, currents, phytoplankton, water quality parameters, dissolved nutrients, and analysis and presentation of quantitative data. Using this pedagogical model allowed the basic structure of the course to remain the same over the years, while enabling us to flexibly respond to changes in the needs and interests of community partners.

    A multi-species spawning aggregation located on the banks south of St. Thomas includes several economically important fish species, including dog snapper, yellowfin grouper, Nassau grouper, and tiger grouper. Increased fishing pressure on these banks has prompted the Caribbean Fisheries Council to take actions such as seasonally closing fishing grounds and establishing Marine Protected Areas (MPAs). Due to a lack of biological and oceanographic data for the region, these management decisions have been based on professional judgment rather than scientific data. In response to this situation, NOAA scientists from SEFSC and AOML began an interdisciplinary field study in the region in 2007. Research cruises utilize biological sampling techniques such as MOCNESS, neuston, and bongo trawl tows simultaneously with standard physical sampling methods such as CTD/LADCP casts, hull- mounted water velocity measurements, and Lagrangian drifter deployments. The three year project aims to determine how the unprotected banks of the Virgin Islands and surrounding region, the seasonally closed banks and MPAs, and near-shore areas are ecologically linked in terms of larval dispersal, transport, and life history patterns. This collaboration should produce an assessment, based on scientific data, of the effectiveness of Caribbean Research Council management decisions and suggest modifications and improvements to current policy. Additionally, this project will also provide fisheries independent data, and develop ecological indices which can be integrated into stock assessment models. Analysis of data gathered during the project's first research cruise is yielding preliminary results. A total of 26,809 fish larvae were collected from the Grammanik and Red Hind Banks and surrounding regions. Of this total, 585 Serranidae (grouper) and 93 Lutjanidae (snapper) larval specimens were collected. Typical sampling transects included near-shore, shelf-break, and offshore regimes. The most economically important species were recovered at the near-shore sites, south of St. Thomas, St. John, and British Virgin Islands and not on the reef /shelf-break sites as expected. Concurrent Lagrangian drifter trajectories and shipboard ADCP measurements showed a high degree of variability in regional surface water flow. Possible transport pathways as related to the spatial distribution of the larvae collected and the physical oceanography observed will be discussed.

    Science educators working directly with scientists to develop inquiry-based instructional materials in Earth science yield some of the best results. The TEXTEAMS (Texas Teachers Empowered for Achievement in Mathematics and Science) Leadership Training for the Texas high school science course, Geology, Meteorology and Oceanography (GMO) is one example of a successful program that provides high-quality training to master teachers using geophysical data collected by scientists at The University of Texas Institute for Geophysics (UTIG). TEXTEAMS is a certification program of professional development and leadership training sponsored by the National Science Foundation that is part of the Texas Statewide Systemic Initiative. UTIG scientists teamed with science educators at the Charles A. Dana Center for Mathematics and Science Education at UT and the Texas Education Agency to develop inquiry-based instructional materials for eight GMO modules. Our learning activities help students and teachers understand how Earth scientists interpret the natural world and test their hypotheses, and provide opportunities for the use of technology in classroom science learning; they are aligned with national and state teaching standards. Examples of TEXTEAMS GMO learning activities that use geophysical data. 1. Neotectonics: radiocarbon dates and elevation above current sea level of raised coral reefs in the New Georgia Islands are used to calculate rates of tectonic uplift and as a basis for the development of a conceptual model to explain the pattern of uplift that emerges from the data. 2. Large Igneous Provinces:geophysical logging data collected on ODP Leg 183 (Kerguelen Plateau) are analyzed to identify the transition from sediment to basement rock. 3. The Search for Black Gold: petroleum exploration requires the integration of geology, geophysics, petrophysics and geochemistry. Knowledge gained in previous GMO modules is combined with fundamental knowledge about economics to construct a petroleum prospect for a small oil and gas company. TEXTEAMS GMO Leadership Training uses mentoring of teachers by fellow teachers to implement effective teaching strategies and rigorous science curricula. More than 75 GMO teachers participated in the institutes and they in turn have trained about 2,250 other teachers. The number of students reached is about 67,500. The success of the GMO institutes have led to new partnerships between scientists and educators, and allowed UTIG to secure additional funds to promote K-12 Earth science education in Texas. They can serve as a template for other programs that are relevant to local communities and which utilize geophysical data and science.

  18. Putting the Deep Biosphere on the Map for Oceanography Courses: Gas Hydrates As a Case Study for the Deep Biosphere

    NASA Astrophysics Data System (ADS)

    Sikorski, J. J.; Briggs, B. R.

    2014-12-01

    The ocean is essential for life on our planet. It covers 71% of the Earth's surface, is the source of the water we drink, the air we breathe, and the food we eat. Yet, the exponential growth in human population is putting the ocean and thus life on our planet at risk. However, based on student evaluations from our introductory oceanography course it is clear that our students have deficiencies in ocean literacy that impact their ability to recognize that the ocean and humans are inextricably connected. Furthermore, life present in deep subsurface marine environments is also interconnected to the study of the ocean, yet the deep biosphere is not typically covered in undergraduate oceanography courses. In an effort to improve student ocean literacy we developed an instructional module on the deep biosphere focused on gas hydrate deposits. Specifically, our module utilizes Google Earth and cutting edge research about microbial life in the ocean to support three inquiry-based activities that each explore different facets of gas hydrates (i.e. environmental controls, biologic controls, and societal implications). The relevant nature of the proposed module also makes it possible for instructors of introductory geology courses to modify module components to discuss related topics, such as climate, energy, and geologic hazards. This work, which will be available online as a free download, is a solid contribution toward increasing the available teaching resources focused on the deep biosphere for geoscience educators.

  19. The social oceanography of top oceanic predators and the decline of sharks: A call for a new field

    NASA Astrophysics Data System (ADS)

    Jacques, Peter J.

    2010-07-01

    The decline of top oceanic predators (TOPs), such as great sharks, and worldwide erosion of the marine food web is among the most important functional changes in marine systems. Yet, even though human pressures on sharks are one of the most important factors in the collapse of TOPs, the social science of shark fishing has not kept pace with the biophysical science. Such a gap highlights the need for a marine social science, and this paper uses the case of sharks to illustrate some advances that a coherent marine social science community could bring to science and sustainability, and calls for the development of this new field. Social oceanography is proposed as a “discursive space” that will allow multiple social science and humanities disciplines to holistically study and bring insight to a diverse but essential community. Such a community will not provide answers for the physical sciences, but it will add a new understanding of the contingencies that riddle social behavior that ultimately interact with marine systems. Such a field should reflect the broad and diverse approaches, epistemologies, philosophies of science and foci that are in the human disciplines themselves. Social oceanography would complete the triumvirate of biological and physical oceanography where human systems profoundly impact these other areas. This paper tests the theory that institutional rules are contingent on social priorities and paradigms. I used content analysis of all available (1995-2006) State of the World Fisheries and Aquaculture (SOFIA) reports from the United Nations Food and Agricultural Organization (FAO) to measure the symbolic behavior-i.e., what they say-as an indication of the value of sharks in world fisheries. Similar tests were also performed for marine journals and the Convention on Migratory Species of Wild Animals to corroborate these findings. Then, I present an institutional analysis of all international capacity building and regulatory institutions as they pertain to sharks. We find that sharks are not a high priority compared to other fisheries; and, amongst issue areas, ecological concerns are overshadowed by a paradigm of economism (economic values are demonstrated above all others). Further, sharks have no global binding institutions for conservation, and only new and problematic rules at regional levels. Consequently, human pressures on sharks are partially explained through social marginalization that legitimizes permissive international rules that: (1) have limited scope of authority, (2) provide little-to-no active management of sharks, (3) have important enforcement problems, and (4) are generally not reinforced with National Plans of Action demonstrating a lack of commitment at both national and international scales. Thus, active management of shark populations is nearly non-existent meanwhile pressures on sharks, such as through finning, have increased in the last 20 years and there is strong evidence that many shark species are in decline and may not be able to recover. This paper concludes by arguing that biological oceanography of sharks is fundamentally linked to human dimensions, and, therefore, theories and systematic study of human dimensions in oceanography are crucial to provide more comprehensive understanding of complete social-marine systems.

  20. Characteristics of low-carbon data centres

    Data centre services hold promise for reducing societal carbon emissions, but an imperfect and evolving portfolio of performance metrics obscures which data centre characteristics correspond to low-carbon operations. Meanwhile, policymakers face a pressing question: can we identify and promote tangible characteristics that reliably represent low-carbon data centres today while the world awaits better metrics? Fortunately, data centre energy models can provide actionable guidance. Here, we present results that identify such characteristics and illuminate the factors that govern a data centre's actual carbon performance. These results can help public and private sector policymakers accelerate the transition to a low-carbon Internet by aligning data centre incentives with factors that truly matter.

  1. An Assessment of Student Learning in an Online Oceanography Course: Five Years After Implementation

    NASA Astrophysics Data System (ADS)

    Reed, D. L.

    2002-12-01

    The results of assessing student learning in an online oceanography class offered over the past five years are compiled to reveal several general trends. In order to understand the context of these trends, it is important to first note that SJSU has a two-tiered general education program consisting of a category of core courses for frosh and sophomores and an advanced category for juniors and seniors, most of whom are community college transfers. The course described in this study is in the latter category and therefore composed largely of seniors. Enrollments in the course have exploded from 6 students in a pilot section offered during the 1998 fall semester to over 170 students in the summer semester of 2002. The course is now offered in both semesters of the academic year with four sections offered during 2002 summer session as part of a system-wide conversion to year-round operation. No other course, be it classroom, hybrid or online, in the general education category has experienced the level of student demand as this online course. All sections of the online course reach enrollment limits in the first days of registration with an equal or greater number of students turned away each semester. More female, students of color, returning students and K-12 in-service teachers enroll in the online sections than in the equivalent classroom sections of the course. Students enroll in the online section for the convenience of self-paced learning since attending a classroom section is not a viable option. Enrollments in concurrent classroom sections have not been negatively impacted by the addition of online sections. Enrollment attrition is higher in the first few days of the online course, but similar to that experienced in the classroom sections, once the class is underway. However, student requests for incompletes tend to be somewhat higher in the online course, especially during the summer offerings. Learning outcomes are reviewed at the beginning of the course and subsequent assessment on achieving each outcome is embedded in the graded assignments, which include a critical thinking essay on declining marine fisheries, one mid-term exam that emphasizes the application of basic math and the methods of scientific discovery in the context of ocean research; poster presentations in a symposium-style format, a course portfolio of web-based work, weekly discussions on an electronic bulletin board and a take-home final consisting of an original research grant proposal. The diverse nature of the graded assignments assures a comprehensive assessment of student learning from a number of perspectives, such as quantitative, qualitative, and analytical. Student learning compares favorably with classroom sections of the course, even though some students lack the discipline for self-paced learning. The distribution of the course grades in the online section typically differs from classroom sections by having higher percentages of both high and low performing students and fewer students clustered about the mean. Students strongly affirm that communication with the instructor in the online course is far greater, and of higher quality, than in classroom sections.

  2. The MIT/WHOI Joint Program in Oceanography and Applied Ocean Science and Engineering: An Ongoing Experiment in Graduate Education and the Sverdrup, Johnson and Fleming Influence.

    2002-12-01

    On May 8, 1968 Paul M. Fye, President of Woods Hole Oceanographic Institution and Howard W. Johnson, President of Massachusetts Institute of Oceanography, signed a Memorandum of Agreement of one and one-half pages in which both partner institutions "have each approved the creation of a Joint Graduate Program in Oceanography for which there will be established appropriate graduate degrees to be conferred jointly by the Massachusetts Institute of Technology and Woods Hole Oceanographic Institution." The partnership brought together the MIT experience with formal graduate education in sciences and engineering involving classroom instruction and more traditional academic advising with the less formal one to one "apprenticeship" or European tutorial style of education at WHOI. During the first year the graduate program involved only the physical sciences with the MIT home being in the Earth, Atmospheric and Planetary Sciences Department. Ocean Engineering was added the following year with the MIT home being the Ocean Engineering Department. Biological Oceanography was added in 1970 with the MIT home being the Biology Department. The existing graduate curricula of the home departments at MIT, the inclusion of ocean engineering, and the fact that several of the early program instructors and advisers at WHOI entered oceanography after formal graduate training in more traditional disciplines such as chemistry, geology, physics, biology and mathematics was not conducive to an automatic adoption of the Sverdrup, Johnson and Fleming paradigm of core courses that predominated in other leading graduate programs in oceanography. Despite this caveat, the Sverdrup, Johnson and Fleming paradigm has influenced the learning environment in the Joint Program. Taking into account lessons learned in the process, some suggestions for the future of graduate education in ocean sciences and ocean engineering will be presented.

  3. Adenylate cyclase-centred microdomains.

    Cooper, Dermot M F; Tabbasum, Valentina G

    2014-09-01

    Recent advances in the AC (adenylate cyclase)/cAMP field reveal overarching roles for the ACs. Whereas few processes are unaffected by cAMP in eukaryotes, ranging from the rapid modulation of ion channel kinetics to the slowest developmental effects, the large number of cellular processes modulated by only three intermediaries, i.e. PKA (protein kinase A), Epacs (exchange proteins directly activated by cAMP) and CNG (cyclic nucleotide-gated) channels, poses the question of how selectivity and fine control is achieved by cAMP. One answer rests on the number of differently regulated and distinctly expressed AC species. Specific ACs are implicated in processes such as insulin secretion, immunological responses, sino-atrial node pulsatility and memory formation, and specific ACs are linked with particular diseased conditions or predispositions, such as cystic fibrosis, Type 2 diabetes and dysrhythmias. However, much of the selectivity and control exerted by cAMP lies in the sophisticated properties of individual ACs, in terms of their coincident responsiveness, dynamic protein scaffolding and organization of cellular microassemblies. The ACs appear to be the centre of highly organized microdomains, where both cAMP and Ca2+, the other major influence on ACs, change in patterns quite discrete from the broad cellular milieu. How these microdomains are organized is beginning to become clear, so that ACs may now be viewed as fundamental signalling centres, whose properties exceed their production of cAMP. In the present review, we summarize how ACs are multiply regulated and the steps that are put in place to ensure discrimination in their signalling. This includes scaffolding of targets and modulators by the ACs and assembling of signalling nexuses in discrete cellular domains. We also stress how these assemblies are cell-specific, context-specific and dynamic, and may be best addressed by targeted biosensors. These perspectives on the organization of ACs uncover new strategies for intervention in systems mediated by cAMP, which promise far more informed specificity than traditional approaches.

  4. Smooth 2-D ocean sound speed from Laplace and Laplace-Fourier domain inversion of seismic oceanography data

    2016-02-01

    In seismic oceanography, processed images highlight small temperature changes, but inversion is needed to obtain absolute temperatures. Local search-based full waveform inversion has a lower computational cost than global search but requires accurate starting models. Unfortunately, most marine seismic data have little associated hydrographic data and the band-limited nature of seismic data makes extracting the long wavelength sound speed trend directly from seismic data inherently challenging. Laplace and Laplace-Fourier domain inversion (LDI) can use rudimentary starting models without prior information about the medium. Data are transformed to the Laplace domain, and a smooth sound speed model is extracted by examining the zero and low frequency components of the damped wavefield. We applied LDI to five synthetic data sets based on oceanographic features and recovered smoothed versions of our synthetic models, showing the viability of LDI for creating starting models suitable for more detailed inversions.

    Introduction The European haemophilia community of professionals and patients has agreed on the principles of haemophilia care to address comprehensive optimal delivery of care which is nowadays scattered throughout Europe. Many of the health facilities call themselves Haemophilia Centres despite their variation in size, expertise and services provided. Only a small number of countries have Haemophilia Centre accreditation systems in place. Methods In the framework of the European Haemophilia Network project, following an inclusive process of stakeholder involvement, the European Guidelines for the certification of haemophilia centres have been developed in order to set quality standards for European Haemophilia Centres and criteria for their certification. Results The Guidelines define the standards and criteria for the designation of two levels of care delivery: European Haemophilia Treatment Centres, providing local routine care, and European Haemophilia Comprehensive Care Centres, providing specialised and multi-disciplinary care and functioning as tertiary referral centres. Additionally, they define standards about general requirements, patient care, provision of an advisory service and establishment of network of clinical and specialised services. Conclusions The implementation of the European Guidelines for the certification of Haemophilia Centres will contribute to the reduction of health inequalities through the standardisation of quality of care in European Union Member States and could represent a model to be taken into consideration for other rare disease groups.

    The Canadian Astronomy Data Centre (CADC) is the world's largest astronomical data center, holding over 0.5 Petabytes of information, and serving nearly 3000 astronomers worldwide. Its current data collections include BLAST, CFHT, CGPS, FUSE, Gemini, HST, JCMT, MACHO, MOST, and numerous other archives and services. It provides extensive data archiving, curation, and processing expertise, via projects such as MegaPipe, and enables substantial day-to-day collaboration between resident astronomers and computer specialists. It is a stable, powerful, persistent, and properly supported environment for the storage and processing of large volumes of data, a condition that is now absolutely vital for their science potential to be exploited by the community. Through initiatives such as the Common Archive Observation Model (CAOM), the Canadian Virtual Observatory (CVO), and the Canadian Advanced Network for Astronomical Research (CANFAR), the CADC is at the global forefront of advancing astronomical research through improved data services. The CAOM aims to provide homogeneous data access, and hence viable interoperability between a potentially unlimited number of different data collections, at many wavelengths. It is active in the definition of numerous emerging standards within the International Virtual Observatory, and several datasets are already available. The CANFAR project is an initiative to make cloud computing for storage and data-intensive processing available to the community. It does this via a Virtual Machine environment that is equivalent to managing a local desktop. Several groups are already processing science data. CADC is also at the forefront of advanced astronomical data analysis, driven by the science requirements of astronomers both locally and further afield. The emergence of 'Astroinformatics' promises to provide not only utility items like object classifications, but to directly enable new science by accessing previously undiscovered or intractable information. We are currently in the early stages of implementing Astroinformatics tools, such as machine learning, on CANFAR.

    2007-12-01

    Planetary exploration by means of radar systems, mainly using Ground Penetrating Radars (GPR) plays an important role in Italy. Numerous scientific international space programs are currently carried out jointly with ESA and NASA by Italian Space Agency, the scientific community and the industry. Three important experiments under Italian leadership ( designed and manufactured by the Italian industry), provided by ASI either as contribution to ESA programs either within a NASA/ASI joint venture framework, are now operating: MARSIS on-board Mars Express, SHARAD on-board Mars Reconnaissance Orbiter and CASSINI Radar on-board Cassini spacecraft. In order to support all the scientific communities, institutional customers and experiment teams operation three Italian dedicated operational centers have been realized, namely SHOC, (Sharad Operating Centre), MOC (Marsis Operating Center) and CASSINI PAD ( Processing Altimetry Data). Each center is dedicated to a single instrument management and control, data processing and distribution. Although they had been conceived to operate autonomously and independently one from each other, synergies and overlaps have been envisaged leading to the suggestion of a unified center, the Planetary Radar Processing Center (PROC). PROC is conceived in order to include the three operational centers, namely SHOC, MOC and CASSINI PAD, either from logistics point of view and from HW/SW capabilities point of view. The Planetary Radar Processing Center shall be conceived as the Italian support facility to the scientific community for on-going and future Italian planetary exploration programs. Therefore, scalability, easy use and management shall be the design drivers. The paper describes how PROC is designed and developed, to allow SHOC, MOC and CASSINI PAD to operate as before, and to offer improved functionalities to increase capabilities, mainly in terms of data exchange, comparison, interpretation and exploitation. Furthermore, in the frame of an operative experimental platform, where a specific payload ( to be developed by the Italian Industry) a GPR will be accommodated on-board the Italian Space Agency stratospheric balloon and the data analysed by PROC; as a minimum two flight campaigns over polar regions are foreseen. The system shall be capable of acquiring radar data upon scientists requests in order to help them refine their models, experiment new algorithms, improve data interpretation capabilities. The paper also describes how the system will be integrated in the PROC, sharing the operational resources and aiding scientists to increase their knowledge in the field of surface radar sounding. A specific PROC Web facility is foreseen to allow data gathering, request submission, data exchange and dissemination.

    Patient-centred care is a model of care that respects the patient's experience, values, needs and preferences in the planning, co-ordination and delivery of care. A central component of this model is a therapeutic relationship between the patient and the team of healthcare professionals. The implementation of a patient-centred care model has been shown to contribute to improved outcomes for patients, better use of resources, decreased costs and increased satisfaction with care. This article provides an overview of the barriers to providing patient-centred care and identifies strategies that can be implemented to overcome them. PMID:26394978

    The TOPEX/POSEIDON space mission, sponsored by NASA and France's space agency, the Centre National d'Etudes Spatiales (CNES), will give new observations of the Earth from space to gain a quantitative understanding of the role of ocean currents in climate change. Rising atmospheric concentrations of carbon dioxide and other 'greenhouse gases' produced as a result of human activities could generate a global warming, followed by an associated rise in sea level. The satellite will use radar altimetry to measure sea-surface height and will be tracked by three independent systems to yield accurate topographic maps over the dimensions of entire ocean basins. The satellite data, together with the Tropical Ocean and Global Atmosphere (TOGA) program and the World Ocean Circulation Experiment (WOCE) measurements, will be analyzed by an international scientific team. By merging the satellite observations with TOGA and WOCE findings, the scientists will establish the extensive data base needed for the quantitative description and computer modeling of ocean circulation. The ocean models will eventually be coupled with atmospheric models to lay the foundation for predictions of global climate change.

  15. Towards Human-Centred Design

    NASA Astrophysics Data System (ADS)

    Bannon, Liam J.

    The field of HCI has evolved and expanded dramatically since its origin in the early 1980’s. The HCI community embraces a large community of researchers and practitioners around the world, from a variety of disciplinary backgrounds in the human and social sciences, engineering and informatics, and more recently, the arts and design disciplines. This kaleidoscope of cultures and disciplines as seen at INTERACT Conferences provides a rich pool of resources for examining our field. Applications are increasingly exploring our full range of sensory modalities, and merging the digital and physical worlds. WiFi has opened up a huge design space for mobile applications. A focus on usability of products and services has been complemented by an emphasis on engagement, enjoyment and experience. With the advent of ubiquitous computing, and the emergence of “The Internet of Things”, new kinds of more open infrastructures make possible radically new kinds of applications. The sources of innovation have also broadened, to include human and social actors outside of the computing and design organizations. The question is to what extent is our mainstream thinking in the HCI field ready for the challenges of this Brave New World? Do the technological and social innovations that we see emerging require us to re-shape, or even, re-create, our field, or is it a case of a more gradual evolution and development of that which we already know? In this closing Keynote, I will provide a perspective on the evolution and development of the HCI field, looking backwards as well as forwards, in order to determine what are some of the changes of significance in the field. This “broad-brush” approach to what I term “ human-centred design” will be complemented by the examination of specific projects and applications, to help anchor some of the discussion. Areas such as user-centred design, participatory design, computer-supported cooperative work and learning, and interaction design, in which I have had some involvement over the years, will be mentioned. I will discuss the themes of “ecologies of artefacts”, appropriation, tinkering/bricolage, and the emergence of design anthropology, among other topics. The purpose of the talk is not to engage in a form of Futurism concerning the HCI field, but to examine some of the technical and social trends that can be observed, and to highlight some areas of particular significance that warrant further attention. I argue for a multi-layered approach that, while exploring new avenues of research concerning people’s use of technology, does not necessarily dismiss the corpus of knowledge we have built up over the years concerning human-computer interaction. From a personal perspective, issues such as means and ends, our underlying values, and concern for our fellow human beings in an increasingly fragile world, are issues that, while perhaps seen as outside the remit of a narrow HCI brief, impact on the field in significant ways. In this regard, discussions of our future should not be the preserve of techno-determinists, but be open to all. For example, ubiquitous computing can be involved in many scenarios, not only that of “Ambient Intelligence”. We need to engage in the development and critique of these different perspectives and approaches. Being able to work in and with multidisciplinary teams embodying distint, and at times conflicting perspectives, being able to communicate ones ideas and information across a variety of social and institutional boundaries, will become of great importance. Of particular concern, in the context of an IFIP INTERACT event, is the need to balance the heterogeneity of concepts and methods being used in research and practice with some form of quality control. Despite the heterogeneity of perspectives and disciplines nowadays involved in the field, I will argue that the HCI community, as a community, still does have a significant role to play in the development and evolution of useful, usable and enaging ICT-enabled infrastructures and applications.

  16. Identity Theft: A Study in Contact Centres

    NASA Astrophysics Data System (ADS)

    Moir, Iain; Weir, George R. S.

    This paper explores the recent phenomenon of identity theft. In particular, it examines the contact centre environment as a mechanism for this to occur. Through a survey that was conducted amongst forty-five contact centre workers in the Glasgow area we determined that contact centres can and do provide a mechanism for identity theft. Specifically, we found a particularly high incidence of agents who had previously dealt with phone calls that they considered suspicious. Furthermore, there are agents within such environments who have previously been offered money in exchange for customers' details, or who know of fellow workers who received such offers. Lastly, we identify specific practices within contact centres that may contribute to the likelihood of identity theft.

    This project centers around the Strategic Petroleum Site (SPR) known as the West Hackberry salt dome which is located in southwestern Louisiana and which is designed to store 241 million barrels of crude oil. Oil storage caverns are formed by injecting water into salt deposits, and pumping out the resulting brine. Studies described in this report were designed as follow-on studies to three months of pre-discharge characterization work, and include data collected during the first year of brine leaching operations. The objectives were to: (1) characterize the environment in terms of physical, chemical and biological attributes; (2) determine if significant adverse changes in ecosystem productivity and stability of the biological community are occurring as a result of brine discharge; and (3) determine the magnitude of any change observed. Volume IV contains the following: bibliography; appendices for supporting data for physical oceanography, and summary of the physical oceanography along the western Louisiana coast.

    The IUPAC Thermodynamic Tables Project Centre in London has at its disposal considerable expertise on the production and utilization of high-accuracy equations of state which represent the thermodynamic properties of substances. For some years they have been content to propagate this information by the traditional method of book production, but the increasing use of the computer in industry for process design has shown that an additional method was needed. The setting up of the IUPAC Transport Properties Project Centre, also at Imperial College, whose products would also be in demand by industry, afforded the occasion for a new look at the problem. The solution has been to set up the Imperial College Thermophysical Properties Data Centre, which embraces the two IUPAC Project Centres, and for it to establish a link with the existing Physical Properties Data Service of the Institution of Chemical Engineers, thus providing for the dissemination of the available information without involving the Centres in problems such as those of marketing and advertising. This paper outlines the activities of the Centres and discusses the problems in bringing their products to the attention of industry in suitable form.

    Lithologic data from 40 DSDP, ODP, and IODP scientific ocean drilling cores from the Pacific and North Atlantic oceans are the basis for an inquiry-based classroom exercise module for college introductory geology and oceanography courses. Part 1 of this exercise module is designed as an initial inquiry aimed at drawing out student beliefs and prior knowledge. In Parts 2-3 students observe and describe the physical characteristics of sediment cores using digital core photos, and determine the sediment composition using smear slide data and a decision tree. In Part 4 students combine their individual site data to construct a map showing the distribution of the primary marine sediment types of the Pacific and North Atlantic Oceans, and develop hypotheses to explain the distribution of the sediment types shown on their map. The transportable skills of observation, forming questions, plotting data, interpreting data, and scientific synthesis are embedded in this module, benefitting non-majors as well as majors. The exercise module was tested in the 2008 School of Rock program and the 2008 Urbino Summer School for Paleoceanography, and is currently being tested in undergraduate courses at James Madison University, North Hennipen Community College, St. Cloud State University and University of Massachusetts, Amherst in classes that range in size from 16 students to >150 students. The student worksheets, instructor guide, and preliminary evaluation data will be presented.

    The high-resolution and coupled forecasting of wind, waves and currents, in restricted coastal domains, offer a number of important challenges; these limit the quality of predictions, in the present state-of-the-art. This paper presents the main results obtained for such coastal domains, with reference to a variety of modelling suites and observing networks for: a) Liverpool Bay; b) German Bight; c) Gulf of Venice; and d) the Catalan coast. All of these areas are restricted domains, where boundary effects play a significant role in the resulting inner dynamics. This contribution addresses also the themes of the other papers in this Special Issue, ranging from observations to simulations. Emphasis is placed upon the physics controlling such restricted areas. The text deals also with the transfer to end-users and other interested parties, since the requirements on resolution, accuracy and robustness must be linked to their applications. Finally, some remarks are included on the way forward for coastal oceanography and the synergetic combination of in-situ and remote measurements, with high-resolution 3D simulations.

    The Physical Oceanography Distributed Active Center (PO.DAAC) serves as the designated NASA repository and distribution node for all Aquarius/SAC-D data products in close collaboration with the project. Here we report on the status of Aquarius data holdings at PO.DAAC, observed patterns of usage of these datasets, and the range of data services and access tools that we provide in support of this mission. These currently include dataset discovery and access via the PO.DAAC web-portal, an interactive L3-browser tool for online visualization, and user services that span help-desk support, Aquarius user guide documentation, and reader software development. In anticipation of the release of the Aquarius science quality dataset by the end of 2012 and as the project transitions out of the current calibration/evaluation phase, additional PO.DAAC tools and services that will be leveraged for Aquarius are described. These range from OPeNDAP and THREDDS data access services, web-based visualization via PO.DAAC's SOTO tool and LAS, to our advanced L2 subsetting tool called HITIDE.

We describe the infrastructure, computing, software, and communications systems required to create an effective and affordable CMS Centre. We present our highly successful operations experiences with the major CMS Centres at CERN, Fermilab, and DESY during the LHC first beam data-taking and cosmic ray commissioning work. The status of the various centres already operating or under construction in Asia, Europe, Russia, South America, and the USA is also described. We emphasise the collaborative communications aspects. For example, virtual co-location of experts in CMS Centres Worldwide is achieved using high-quality permanently-running 'telepresence' video links. Generic Web-based tools have been developed and deployed for monitoring, control, display management and outreach.

    The principles of patient-centred care are increasingly stressed as part of health care policy and practice. Explanations for why some practitioners seem more successful in achieving patient-centred care vary, but a possible role for individual differences in personality has been postulated. One of these, emotional intelligence (EI), is increasingly referred to in health care literature. This paper reviews the literature on EI in health care and poses a series of questions about the links between EI and patient-centred outcomes. Papers concerning empirical examinations of EI in a variety of settings were identified to determine the evidence base for its increasing popularity. The review suggests that a substantial amount of further research is required before the value of EI as a useful concept can be substantiated. PMID:17682030

  5. Optimizing Data Centre Energy and Environmental Costs

    NASA Astrophysics Data System (ADS)

    Aikema, David Hendrik

    Data centres use an estimated 2% of US electrical power which accounts for much of their total cost of ownership. This consumption continues to grow, further straining power grids attempting to integrate more renewable energy. This dissertation focuses on assessing and reducing data centre environmental and financial costs. Emissions of projects undertaken to lower the data centre environmental footprints can be assessed and the emission reduction projects compared using an ISO-14064-2-compliant greenhouse gas reduction protocol outlined herein. I was closely involved with the development of the protocol. Full lifecycle analysis and verifying that projects exceed business-as-usual expectations are addressed, and a test project is described. Consuming power when it is low cost or when renewable energy is available can be used to reduce the financial and environmental costs of computing. Adaptation based on the power price showed 10--50% potential savings in typical cases, and local renewable energy use could be increased by 10--80%. Allowing a fraction of high-priority tasks to proceed unimpeded still allows significant savings. Power grid operators use mechanisms called ancillary services to address variation and system failures, paying organizations to alter power consumption on request. By bidding to offer these services, data centres may be able to lower their energy costs while reducing their environmental impact. If providing contingency reserves which require only infrequent action, savings of up to 12% were seen in simulations. Greater power cost savings are possible for those ceding more control to the power grid operator. Coordinating multiple data centres adds overhead, and altering at which data centre requests are processed based on changes in the financial or environmental costs of power is likely to increase this overhead. Tests of virtual machine migrations showed that in some cases there was no visible increase in power use while in others power use rose by 20--30W. Estimates of how migration was likely to impact other services used in current cloud environments were derived.

  6. Bureaucracy, professionalization and school centred innovation strategies

    1990-03-01

    This paper examines an attempt to promote a school centred innovation strategy within a highly centralized educational system. The School Based Curriculum Project Scheme, which was introduced into Hong Kong in 1988, is analysed in terms of a professional-bureaucratic dichotomy. It is argued that the operational details of the scheme are designed to satisfy a range of bureaucratic concerns and these are not conducive to promoting the professional work ethic which is required for school centred innovation. Finally the paper identifies the implications which arise for policies designed to promote curriculum innovation.

    Effective communication is necessary for good relationships between healthcare practitioners and clients. This study examined barriers and facilitators to implementing new communication skills. One hundred and ten Sure Start Children's Centre staff attended one of 13 follow-up workshops in Southampton, UK between May 2009 and February 2011 to reflect on the use of new skills following a training course in communication, reflection and problem-solving. Barriers and facilitators were assessed with an adapted Problematic Experiences of Therapy scale (PETS). Staff reported frequency of skill use, and described what made it more difficult or easier to use the skills. Complete data were available for 101 trainees. The PETS indicated that staff had confidence in using the skills, but felt that there were practical barriers to using them, such as lack of time. Skills were used less often when staff perceived parents not to be engaging with them (Spearman's correlation r(s) = -0.42, P < 0.001), when staff felt less confident to use the skills (r(s) = -0.37, P < 0.001) and when there were more practical barriers (r(s) = -0.37, P < 0.001). In support of findings from the PETS, content analysis of free text responses suggested that the main barrier was a perceived lack of time to implement new skills. Facilitators included seeing the benefits of using the skills, finding opportunities and having good relationships with parents. Understanding the range of barriers and facilitators to implementation is essential when developing training to facilitate ongoing support and sustain skill use. Special attention should be given to exploring trainees' perceptions of time, to be able to address this significant barrier to skill implementation. Staff training requires a multi-faceted approach to address the range of perceived barriers. PMID:22452549

  8. Tracking cold bottom water in the Gargano Peninsula and Bari Canyon regions of the Adriatic using seismic oceanography

    Tracking cold, dense bottom water from conventional ship sampling is difficult - equipment safety concerns result in incomplete sampling near the seafloor, and lateral variability can be significant. Mooring time series are poor at mapping dense water vein spatial extents and can even completely miss sampling narrow veins. The relatively new technique of seismic oceanography (SO) could potentially provide a new way of identifying and characterizing these bottom waters that is not as subject to the constraints and difficulties of present methods. Furthermore, combining SO with conventional sampling is particularly appealing for better characterization of the quick and small scales of dense water cascades and bottom trapped phenomenon.. There is a relationship between oceanic temperatures and the seismic data such that seismic images can be made to represent a quantitative measure of vertical temperature gradient through much of the water column and even very near the seafloor. The SO technique involves towing a low frequency, broadband (20-250 Hz) sound source (such as an air gun array) and a long, 600-1200 m, array of hydrophones. SO uses much lower frequencies than conventional Acoustical Oceanography (AO) techniques, and is affected by the acoustic impedance (product of sound speed and density) directly, not via proxy such as impurities or biota in the water. The sound pulses reflect off the (mostly temperature) contrasts in the water, and are recorded on the hydrophone array, creating an image of temperature gradient. Because the reflection coefficients are small, signal-enhancing techniques such as synthetic aperture (common midpoint binning) processing is required. The images generated using SO allow for the tracking of very thin (less than 10 m thick) bottom currents provided that the temperature contrast between the bottom, and overlying water is strong enough (0.3 to 1.2 degrees C, depending on acoustic noise levels) and abrupt enough (10-15 meters). The lateral resolution of the SO technique is similar to the vertical resolution - therefore adequate to detect changes over as little as 5-10 meters. The images are not an instantaneous snap-shot, but occur over a finite time. Each column of image pixels is a combination of sound pulses that occur over 2-4 minutes, depending on source fire rate and ship speed. In March of 2009 an international SO field effort (AdriaSeismic09) took place the Gargano Peninsula, and Bari Canyon areas of the southern Adriatic Sea. On several seismic profiles through these areas a layer of cold bottom water, between 7 and 10 m thick is clearly imaged. Temperatures in the overlying water typically ranged from 12.5 to 13.5 degrees C, and those of the bottom water typically ranged from 12.0 to 12.5 degrees C. Some of these thin bottom water masses were observed in shallow, coastal waters about 100 m deep and some were as deep as 350m. Undulations with later wavelength of 500m and shorter, and amplitudes of several meters are clearly visible in the upper surfaces of the cold water masses.

  9. High precision finite-differences time-domain direct modelling of wave equation for seismic oceanography experiments

    Sallares, V.; Kormann, J.; Cobo, P.; Biescas, B.; Carbonell, R.

    2007-05-01

    Holbrook et al. (2003) demonstrated recently the possibility of visualizing fine structures in the water column, like thermohaline intrusion or internal waves, through seismic exploration experiments. Seismic exploration is becoming a popular technique for providing high-lateral resolution images of the explored area, in contrast with the classical oceanography probes, like XBT or XCDT. In this work we present a wave propagation model based upon a high order finite-differences time-domain (FDTD) scheme which includes special absorbing conditions in the boundaries. FDTD algorithms are known for presenting problems with reflections on the computational edges. Classical boundary conditions, like those of Engquist, provide reflection coefficients or the order of 10-2. However, reflection coefficients of fine structures in the water we are trying to model are about 10-4. Thus, the key point of the algorithm we present is in the implementation of Perfectly Matched Layer (PML) boundary conditions. These consist in zones with high absorption (therefore, very low reflection coefficient). The PML implemented in this scheme consists in a second order algorithm in the time domain, to take advantage of its stability and convergence properties. In this work we specify the propagation algorithm, and compare it results with the with Engquist and PML absorbing boundaries conditions. The PML condition affords reflection coefficients in the numerical edges lower than 10-4. Holbrook, W.S., Paramo, P., Pearse, S. and Schmitt, R.W., 2003.

    2013-12-01

    Online courses in higher education have garnered a growing presence in the popular media, yet misperceptions abound. Consequently, a retrospective examination of the evolution of an online oceanography class, first offered to undergraduates at the San Jose State University in the fall semester of 1998, may be especially relevant to the development of future efforts in this field. Since that initial offering, the development of the course, involving the creation of virtual field experiences whereby students take on the role of practicing research oceanographers, has been supported through several awards from the National Science Foundation, principally the Division of Undergraduate Education and the Geoscience Directorate. The online material, organized into expeditions, which focus on the nature of scientific discovery, has evolved over time from a static graphics and text-based format to include video, largely available through YouTube, and animations that take advantage of social media, all to highlight contemporary ocean research. To sustain the project beyond NSF funding, the course has been offered throughout the academic year, and in winter and summer special sessions, to more the 4000 students over the 15 year period since its initial offering. The materials have always been openly available through the course website (http://oceansjsu.com) to institutions throughout the world, long in advance of current MOOC movement. Just as the course format, and available content, have evolved, so have the students enrolled in the class, which now more closely mirror the university student body as a whole. Future efforts in course development should span multi-campus university systems to take advantage of the collective scientific expertise available and to leverage the effort across a larger number of courses and disciplines.

    The National Space Centre (NSC) was opened in June 2001 and is a £52M (75M) science-based visitor attraction and education facility with the mission `to promote a wider understanding of space science and technology, and demonstrate its relevance to life on Earth in the 21s t Century'. It is located in the city of Leicester, lying close to the geographical heart of the UK and with 9 million people within a 90 minute drive. The NSC was funded by the Millennium Commission in partnership with the University of Leicester and Leicester City Council, with support from BT, ESA and others. Its main components are an Exhibition, Space Theatre and Challenger Learning Centre. The CLC is the only one operating outside North America and it has been the stimulus for the new "Classroom Space" project which makes data from real space missions available for use in schools, with appropriate support for teachers. Recently the NSC has become the host for the UK's Near Earth Object Information Centre, and it will act as the Operations Centre for the Faulkes (2m class) robotic telescopes to be located in Maui and Siding Springs, providing a unique educational facility for 12-18 year old school students. The first successful year of operation of the NSC will be reported and plans for future national and international development outlined.

  15. The Role of Science Centres and Planetariums

    NASA Astrophysics Data System (ADS)

    Lomb, Nick

    Science centres planetariums and similar places such as visitor centres and public observatories have an essential role to play in school education. Even in states where astronomy is in the curriculum teachers often have a limited knowledge of the subject. Consequently they are happy to bring their students to a place where they can be instructed by professional astronomy educators. Where astronomy is not on the curriculum the centres provide teachers with the opportunity of using the appeal of astronomy to excite students about science. In this paper we will look at a number of examples of what science centres and planetariums provide to school students. Sydney Observatory is open for school visits throughout each school term. Visits are highly structured making use of all the facilities of the observatory in informing the students and exciting them about astronomy. Facilities available include a new interactive 3-D theatre a very small planetarium modern and historic telescopes an exhibition and a lecture room. A planetarium is an invaluable resource for teaching and stimulating the interest of students. Australian planetariums include ones in Melbourne Canberra and Launceston. Some of their experiences in reaching school audiences will be discussed.

  9. The biological oceanography of the East Australian Current and surrounding waters in relation to tuna and billfish catches off eastern Australia

    The surface and sub-surface biological oceanography of tuna fishing grounds within the East Australian Current (EAC) was compared in 2004 with two other fishing areas further offshore. Our aim was to determine whether the biological oceanography of the region could explain the distribution and intensity of pelagic fishery catches inside and outside the EAC at that time. The EAC fishing area was noticeably warmer, less saline and lower in nutrients than waters in the other fishing areas. The EAC waters were dominated by large diatoms, the biomass of which was significantly higher than in the seamount and offshore areas, apparently the result of a cold core eddy beneath the EAC surface filament. Over the seamount and offshore more typical Tasman Sea waters prevailed, although the presence of a relatively deeper oxygen minimum layer over the seamount suggested topographically induced mixing in the area. Notably, sub-surface zooplankton and micronekton biomass was significantly higher around the seamount than in the two other areas. The offshore region was characterised by frontal activity associated with the Tasman front. Micronekton net biomass was generally highest in surface waters in this region. Examination of tuna catch records at that time showed yellowfin tuna ( Thunnus albacares) dominated the catches of the EAC, whereas swordfish ( Xiphias gladius) and bigeye tuna ( Thunnus obesus) were the main species caught offshore. We suggest the yellowfin tuna concentrate in waters that are not only warmer but where prey species are concentrated near the surface. Offshore, deeper living species such as swordfish and bigeye tuna ( T. obesus) can take advantage of prey species that are distributed deeper in the water column and along the flanks of the many seamounts in the region, or that are concentrated at fronts associated with the Tasman Front. Although only a snapshot of the region, relatively consistent catch data over time suggests the underlying biological oceanography may persist over longer time periods, particularly during the Austral spring.

    The CMS Experiment at the LHC has established a network of more than fifty inter-connected "CMS Centres" at CERN and in institutes in the Americas, Asia, Australasia, and Europe. These facilities are used by people doing CMS detector and computing grid operations, remote shifts, data quality monitoring and analysis, as well as education and outreach. We present the computing, software, and collaborative tools and videoconferencing systems. These include permanently running "telepresence" video links (hardware-based H.323, EVO and Vidyo), Webcasts, and generic Web tools such as CMS-TV for broadcasting live monitoring and outreach information. Being Web-based and experiment-independent, these systems could easily be extended to other organizations. We describe the experiences of using CMS Centres Worldwide in the CMS data-taking operations as well as for major media events with several hundred TV channels, radio stations, and many more press journalists simultaneously around the world.

  13. Center of Microbial Oceanography Research and Education (C-MORE) Initiatives Toward Promoting Diversity in the Ocean Sciences

    NASA Astrophysics Data System (ADS)

    Bruno, B. C.

    2007-05-01

    The ocean sciences suffer from a lack of diversity, particularly among indigenous peoples, despite the fact that indigenous peoples often have deep, cultural knowledge about the marine environment. Nowhere is this inequity more glaring than in Hawaii. Traditional knowledge in marine science enabled Native Hawaiians and Pacific Islanders (NHPI) to become world leaders in transpacific canoe voyaging, aquaculture, and fisheries. Yet today, NHPI are severely underrepresented in the ocean sciences (and in STEM fields in general) at all levels of education and employment. When compared to other ethnic and racial groups in Hawaii, NHPI students as a group have among the poorest educational performance, indicated in part by underrepresentation in college enrolment and pre-college gifted and talented programs, as well as overrepresentation in eligibility for special education and free and reduced lunch programs. The Center of Microbial Oceanography Research and Education (C-MORE), a NSF-funded, multi-institutional Science and Technology Center based at the University of Hawai (UH), is determined to address this inequity. C- MORE is committed to increasing diversity in the ocean sciences, particularly among NHPI, at all levels of education and research. Our approach is to work with existing programs with a track record of increasing diversity among NHPI. We are currently developing culturally relevant materials including educational games for K-12 students, mentorships for high school and community college students, and laboratory and shipboard experiences for teachers and undergraduates in partnership with minority-serving organizations. Some of our main partners are EPSCoR (Experimental Program to Stimulate Competitive Research), Ka `Imi `Ike (an NSF- funded program to recruit and retain NHPI undergraduates in geosciences), Upward Bound (an enrichment program for economically disadvantaged high school students which includes intensive summer courses), the UH Center on Disability Studies (which is developing culturally relevant curriculum to address the overrepresentation of NHPI in special education classes) and the UH Louis Stokes Program (which we plan to use as a model).

  14. Late winter oceanography off the Sabrina and BANZARE coast (117-128°E), East Antarctica

    Williams, G. D.; Meijers, A. J. S.; Poole, A.; Mathiot, P.; Tamura, T.; Klocker, A.

    2011-05-01

    We report on the late winter oceanography observed beneath the Antarctic sea ice offshore from the Sabrina and BANZARE coast of Wilkes Land, East Antarctica (117-128°E) in September-October 2007 during the Sea Ice Physics and Ecosystem eXperiment (SIPEX). A pilot program using specifically designed 'through-ice' conductivity-temperature-depth (CTD) and acoustic Doppler current profiling (ADCP) systems was conducted to opportunistically measure water mass properties and ocean currents at major ice stations. Additional water mass properties across the survey region were collected from Ice-Argo floats deployed during the voyage north of the 3000 m isobath. The mean drift of the floats was along the slope to the west with the Antarctic Slope Current. Vertical profiles of the potential temperature reveal the deepest (˜350-400m) winter mixed layer (WML) in the western sector of the survey northwest of the Dalton Iceberg Tongue polynya. The meridional structure of the Antarctic Slope Front, i.e. the monotonic shoaling of the WML across the upper continental slope, is found to be similar to the previous observations in summer. A strong bottom-intensified intrusion of modified Circumpolar Deep Water (mCDW) as warm as 0 °C was detected beneath the fast ice south of the continental shelf break at 118°E. An mCDW intrusion of similar strength was detected near this location in the austral summer of 1996. We hypothesise that there is a persistent supply of mCDW and associated ocean heat flux to this region of the continental shelf that is capable of migrating to the grounding lines of the nearby Totten Glacier and Moscow University Ice Shelf. There was no detection of locally formed dense shelf water capable of forming Antarctic Bottom Water at the shelf break locations sampled despite the number of minor polynyas across this region. Ocean current measurements, limited to a maximum period of 24 h and 50-100 m depth by the relative scarcity of backscatter, found increased mean vertical speeds at the offshore stations (6-17 cm s -1) relative to the shelf break (2.3-6.4 cm s -1). The diurnal variation in the ADCP range reflected the diel migration of zooplankton occurring beneath the sea ice in late winter, with greater range/abundance offshore. Concurrent time series of wind, ocean current and their influence on sea ice drift from global positioning system (GPS) compass measurements were examined but the length of data acquisitions limited the applicability of this analysis.

  15. Deep Thermal Front (southeastern Brazilian coast) see through acoustics: a preliminary study from an operational oceanography perspective

    The continental shelf region off the southeastern Brazilian coast (between 20°S and 28°S) is characterized by intrusions of the relatively cold and fertile South Atlantic Central Water (SACW) from the open ocean. Prediction and monitoring of this water mass are topics of great interest given its importance, for example, on climate, carbon cycle, fishing, mariculture, nutrients and pollutants dispersion, and for the oil industry. The intersection of the 18°C isotherm with the seafloor is appointed in the literature as a good tracer for SACW presence on the continental shelf and also to characterize the Deep Thermal Front (DTF) [Castro, 1996]. Among different factors that drive the SACW penetration on the continental shelf, one prominent mechanism is the water transport driven by the conditions of NE-E wind forcing. These winds varies seasonally, and they are prevalent during the spring and summer months. During these months, the water column is generally stratified due the combined effects of solar heating and DTF presence. In contrast, the reverse effect is characteristic in winter, when the water column is nearly homogeneous, relatively colder on the surface and relatively warm close to the bottom. Consequently, the sound speed field changes and thus the acoustic rays are propagated with different characteristics depending on presence, absence or DTF position. Considering this information, acoustics may provide an additional source of data that supplements the other conventional methods (e.g., hydrographic moorings and cruises, buoys, gliders, and others) for tracking and monitoring the front movement. In addition, it is worth emphasizing that acoustic methods present one interesting advantage in that they are able to sample the water column over large three-dimensional distances on an effectively synoptic scale. In this paper, a preliminary study of acoustic propagation modelling through one vertical section off the Brazilian southeastern coast at Cananéia region (state of São Paulo) is presented. Theorical temperature and salinity fields with differents conditions of DTF position are used for the calculations. Notable variations in the transmission loss field, rays propagations and time arrivals are found when the DTF is moving. These results support the idea that acoustics can be an interesting tool in monitoring and tracking of DTF movement, especially in the context of an intregrated program of observational oceanography and numerical ocean modeling.

    The International Centre for Reproductive Health (ICRH) was established by Prof. dr. Marleen Temmerman in the aftermath of the UN Conference on Population and Development in Cairo in 1994. This conference called for world-wide action to improve the sexual and reproductive health situation of the global population in general and for vulnerable groups in particular, and this is exactly what ICRH is striving for and has been working on for the last 15 years. ICRH is a multidisciplinary centre of excellence, in research, capacity building and fieldwork in sexual and reproductive health and HIV prevention, and an advocate for sexual and reproductive health and rights. Right from the start, ICRH has opted for a global approach, which has resulted in a broad geographical spread of activities, with projects in Africa, Latin America, Asia and Europe. Since its inception, ICRH has participated in more than 120 projects, often as the coordinator, and through this work it has contributed considerably not only to scientific knowledge, improvement of health systems and increased accessibility of health services for vulnerable groups, but also to the quality of live of numerous individuals. Since 2004, ICRH has been recognized as a WHO Collaborating Centre for Research on Sexual and Reproductive Health.

    For the period 1978-1982, this paper examines the nature of the sea ice which forms over the Kuril Basin of the Okhotsk Sea and describes the impact of this ice on the regional oceanography. The oceanographic behavior during the heavy ice season associated with the cold 1979 winter is compared with the behavior during the lighter ice years of 1980 and 1982. Examination of the oceanography in the Okhotsk and the adjacent Pacific shows that the early summer water column structure depends on the heat loss from the Okhotsk during the preceding ice season, the total amount of Okhotsk ice formation, and, specifically, the amount of the ice formation in the Kuril Basin. Following the 1979 ice season, the upper 200-300 m of the Kuril Basin waters were cooler, less saline, and richer in oxygen than for the other years. This modification appears to be a process local to the Kuril Basin, driven by eddy-induced mixing, local cooling, and ice melting.

    Wilson, W. S.

    1981-01-01

    It is pointed out that oceanographers have benefited from the space program mainly through the increased efficiency it has brought to ship operations. For example, the Transit navigation system has enabled oceanographers to compile detailed maps of sea-floor properties and to more accurately locate moored subsurface instrumentation. General descriptions are given of instruments used in satellite observations (altimeter, color scanner, infrared radiometer, microwave radiometer, scatterometer, synthetic aperture radar). It is pointed out that because of the large volume of data that satellite instruments generate, the development of algorithms for converting the data into a form expressed in geophysical units has become especially important.

  4. Satellite oceanography - The instruments

    NASA Technical Reports Server (NTRS)

    Stewart, R. H.

    1981-01-01

    It is pointed out that no instrument is sensitive to only one oceanographic variable; rather, each responds to a combination of atmospheric and oceanic phenomena. This complicates data interpretation and usually requires that a number of observations, each sensitive to somewhat different phenomena, be combined to provide unambiguous information. The distinction between active and passive instruments is described. A block diagram illustrating the steps necessary to convert data from satellite instruments into oceanographic information is included, as is a diagram illustrating the operation of a radio-frequency radiometer. Attention is also given to the satellites that carry the various oceanographic instruments.

    The theoretical basis for remote sensing measurements of climate and ocean dynamics is examined. Consideration is given to: the absorption of electromagnetic radiation in the atmosphere; scattering in the atmosphere; and satellite observations using visible light. Consideration is also given to: the theory of radio scatter from the sea; scatter of centimeter waves from the sea; and the theory of operation of synthetic aperture radars. Additional topics include: the coordinate systems of satellite orbits for oceanographic remote sensing applications; the operating features of the major U.S. satellite systems for viewing the ocean; and satellite altimetry.

    Active and passive spaceborne instruments that can observe the sea are discussed. Attention is given to satellite observations of ocean surface temperature and heating, wind speed and direction, ocean currents, wave height, ocean color, and sea ice. Specific measurements now being made from space are described, the accuracy of various instruments is considered, and problems associated with the analysis of satellite data are examined. It is concluded that the satellites and techniques used by different nations should be sufficiently standard that data from one satellite can be directly compared with data from another and that accurate calibration and overlap of satellite data are necessary to confirm the continuity and homogeneity of the data.

    1999-01-01

    The question of whether the Earth ever passed through a magma ocean stop is of considerable interest. Geochemical evidence strongly suggests that the Moon had a magma ocean and the evidence is mounting that the same was true for Mars. Analyses of mar (SNC) meteorites have yielded insights into the differentiation history of Mars, and consequently, it is interesting to compare that planet to the Earth. Three primary features of An contrast strongly to those of the Earth: (1) the extremely ancient ages of the martian core, mantle, and crust (approx. 4.55 b.y.); (2) the highly depleted nature of the martian mantle; and (3) the extreme ranges of Nd isotopic compositions that arise within the crust and depleted mantle.

    During six week survey (August - October 2009) in Western and Northern coast of Madagascar, the R/V 'Dr. Fridtjof Nansen' has carried out a study of the pelagic ecosystem. In collaboration with Agulhas & Somali Current Large Marine Ecosystems project (ASCLME) and South West Indian Ocean Fisheries Project (SWIOFP), the aim of the survey was to establish the physical, chemical and biological characteristics of the Western Madagascar shelf region as a whole. Along selected hydrographical transects, a total of 182 CTD stations were conducted and ranged to a maximum of 3000 m depth. Water samples were also collected with Niskin bottles at predefined depths. A Seabird 911plus CTD was used to obtain vertical profiles of temperature, salinity and oxygen. As results, along the west and south coast of Madagascar, the shelf is narrow and widen slightly along the north-west coast. In all ten transects the isotherms showed stratified waters from the coast to offshore. A maximum salinity layer was observed at subsurface in all transects. Dissolved oxygen had a maximum at around 500 m depth in all transects. Low fluorescence values were observed in the upper 150-200 m, with maximum values in the range of 0.14-0.22 µg/l at intermediate layers. The conditions were consistent along and between the transects, with more variation observed at transect 9. No upwelling was observed along the western coast. The surface temperature (5 m depth) increased from 22°C in the south to 26°C in the north. The horizontal distribution of surface salinities showed homogenous conditions with values between 35.4psu (south) and 35.0 psu (north). Also starting from the coast to offshore, both the surface temperatures and surface salinities showed homogenous patterns.

    During six week survey (August - September 2008) in Southern and Eastern coast of Madagascar, the R/V 'Dr. Fridtjof Nansen' has carried out a study of the pelagic ecosystem. In collaboration with Agulhas & Somali Current Large Marine Ecosystems project (ASCLME) and South West Indian Ocean Fisheries Project (SWIOFP), the aim of the survey was to establish the physical, chemical and biological characteristics of the Western Madagascar shelf region as a whole. A total of 102 CTD stations were conducted along selected hydrographical transects and ranged to a maximum of 3000 m depth. Water samples were also collected with Niskin bottles at predefined depths. A Seabird 911plus CTD was used to obtain vertical profiles of temperature, salinity and oxygen. As results, the first section between latitude 25o-26oS showed sea surface temperature values ranging between 25oC to 15oC upper 250m depth. As part of the south-west, the shelf is narrow and widen slightly along the tip south of the Island coast. In contrast of the west coast, in all transects performed along the south and the east coast, in most cases, the isotherms showed non stratified waters from the coast to offshore. The presence of the upwelling system in the south-east coast modifies drastically the patterns of all measured parameters. Fluorescence had a maximum values (0.25 µg/l) at surface near the coast in 2nd to 5th transects. Inversely, low temperature values were observed along the south and south-east with minimum values in the range of 18. 5oC-11oC at 50-250 m depth. These conditions were consistent along and between the 2nd to 5th transects, with more variation observed at transect 5. The salinity values (5 m depth) decreased from 35.7 psu in the south to 34.5 psu in the east. The horizontal distribution of oxygen showed non homogenous conditions with values between 5 ml/l (south) and 2.5 ml/l (south-east). Also starting from the coast to offshore, surface temperatures and surface salinities, surface fluorescence and dissolved oxygen showed non homogenous patterns.

    Jones, J. H.

    1999-01-01

    The question of whether the Earth ever passed through a magma ocean stage is of considerable interest. Geochemical evidence strongly suggests that the Moon had a magma ocean and the evidence is mounting that the same was true for Mars. Analyses of martian (SNC) meteorites have yielded insights into the differentiation history of Mars, and consequently, it is interesting to compare that planet to the Earth. Three primary features of Mars contrast strongly to those of the Earth: (i) the extremely ancient ages of the martian core, mantle, and crust (about 4.55 b.y.); (ii) the highly depleted nature of the martian mantle; and (iii) the extreme ranges of Nd isotopic compositions that arise within the crust and depleted mantle. The easiest way to explain the ages and diverse isotopic compositions of martian basalts is to postulate that Mars had an early magma ocean. Cumulates of this magma ocean were later remelted to form the SNC meteorite suite and some of these melts assimilated crustal materials enriched in incompatible elements. The REE pattern of the crust assimilated by these SNC magmas was LREE enriched. If this pattern is typical of the crust as a whole, the martian crust is probably similar in composition to melts generated by small degrees of partial melting (about 5%) of a primitive source. Higher degrees of partial melting would cause the crustal LREE pattern to be essentially flat. In the context of a magma ocean model, where large degrees of partial melting presumably prevailed, the crust would have to be dominated by late-stage, LREE-enriched residual liquids. Regardless of the exact physical setting, Nd and W isotopic evidence indicates that martian geochemical reservoirs must have formed early and that they have not been efficiently remixed since. The important point is that in both the Moon and Mars we see evidence of a magma ocean phase and that we recognize it as such. Several lines of theoretical inference point to an early Earth that was also hot and, perhaps, mostly molten. The Giant Impact hypothesis for the origin of the Moon offers a tremendous input of thermal energy and the same could be true for core formation. And current solar system models favor the formation of a limited number of large (about 1000 km) planetesimals that, upon accreting to Earth, would cause great heating, being lesser versions of the Giant Impact. Several lines of geochemical evidence do not favor this hot early Earth scenario. (i) Terrestrial man-tle xenoliths are sometimes nearly chondritic in their major element compositions, suggesting that these rocks have never been much molten. Large degrees of partial melting probably promote differentiation rather than homogenization. (ii) Unlike the case of Mars, the continental crust probably did not form as a highly fractionated residual liquid from a magma ocean (about 99% crystallization), but, rather, formed in multiple steps. [The simplest model for the formation of continental crust is complicated: (a) about 10% melting of a primitive mantle, making basalt; (b) hydrothermal alteration of that basalt, converting it to greenstone; and (c) 10% partial melting of that greenstone, producing tonalite.] This model is reinforced by the recent observation from old (about 4.1 b.y.) zircons that the early crust formed from an undepleted mantle having a chondritic Lu/Hf ratio. (iii) If the mantle were once differentiated by a magma ocean, the mantle xenolith suite requires that it subsequently be homogenized. The Os isotopic compositions of fertile spinel lherzolites place constraints on the timing of that homogenization. The Os isotopic composition of spinel lherzolites approaches that of chondrites and correlates with elements such as Lu and Al. As Lu and Al concentrations approach those of the primitive mantle, Os isotopic compositions approach chondritic. The Re and Os in these xenoliths were probably added as a late veneer. Thus, the mantle that received the late veneer must have been nearly chondritic in terms of its major elements (excluding Fe). If the mantle that the veneer was mixed into was not al-ready homogenized, then Os isotopes should not correlate with incompatible elements such as Al. Consequently, either early differentiation of the mantle did not occur or the homogenization of this differentiation must have occurred before the late veneer was added. The timing of the late veneer is itself uncertain but presumably postdated core formation at about 4.45 b.y. and did not postdate the 3.8-3.9 b.y. late bombardment of the Moon. This timing based on siderophile elements is consistent with the Hf isotopic evidence cited above. If the Earth, Moon and Mars had magma oceans, the Earth subsequently rehomogenized whereas the Moon and Mars did not. The simplest solution to this observation is that homogenization of igneous differentiates was never necessary on Earth, either because the hypothetical magma ocean never occurred or because this event did not produce mantle differentiation.

    A number of human-centred methodologies—subjective, objective, and combined—are used for slipperiness measurement. They comprise a variety of approaches from biomechanically-oriented experiments to psychophysical tests and subjective evaluations. The objective of this paper is to review some of the research done in the field, including such topics as awareness and perception of slipperiness, postural and balance control, rating scales for balance, adaptation to slippery conditions, measurement of unexpected movements, kinematics of slipping, and protective movements during falling. The role of human factors in slips and falls will be discussed. Strengths and weaknesses of human-centred approaches in relation to mechanical slip test methodologies are considered. Current friction-based criteria and thresholds for walking without slipping are reviewed for a number of work tasks. These include activities such as walking on a level or an inclined surface, running, stopping and jumping, as well as stair ascent and descent, manual exertion (pushing and pulling, load carrying, lifting) and particular concerns of the elderly and mobility disabled persons. Some future directions for slipperiness measurement and research in the field of slips and falls are outlined. Human-centred approaches for slipperiness measurement do have many applications. First, they are utilized to develop research hypotheses and models to predict workplace risks caused by slipping. Second, they are important alternatives to apparatus-based friction measurements and are used to validate such methodologies. Third, they are used as practical tools for evaluating and monitoring slip resistance properties of foot wear, anti-skid devices and floor surfaces. PMID:11794763

    2015-01-01

    Humoral immunity depends on the germinal centre (GC) reaction during which somatically mutated high-affinity memory B cells and plasma cells are generated. Recent studies have uncovered crucial cues that are required for the formation and the maintenance of GCs and for the selection of high-affinity antibody mutants. In addition, it is now clear that these events are promoted by the dynamic movements of cells within and between GCs. These findings have resolved the complexities of the GC reaction in greater detail than ever before. This Review focuses on these recent advances and discusses their implications for the establishment of humoral immunity. PMID:25656706

    With many servers and server parts the environment of warehouse sized data centres is increasingly complex. Server life-cycle management and hardware failures are responsible for frequent changes that need to be managed. To manage these changes better a project codenamed “hardware hound” focusing on hardware failure trending and hardware inventory has been started at CERN. By creating and using a hardware oriented data set - the inventory - with detailed information on servers and their parts as well as tracking changes to this inventory, the project aims at, for example, being able to discover trends in hardware failure rates.

    Objective To characterise current safety practices for the use of oral chemotherapy. Design Written questionnaire survey of pharmacy directors of cancer centres. Setting Comprehensive cancer centres in the United States. Results Respondents from 42 (78%) of 54 eligible centres completed the survey, after consulting with 89 colleagues. Clinicians at 29 centres used handwritten prescriptions, two used preprinted paper prescriptions, and six used electronic systems for most oral chemotherapy prescribing. For six commonly used oral chemotherapies, on average 10 centres required a diagnosis on the prescription, 11 required the protocol number, four required the cycle number, nine required double checking by a second clinician, 14 required a calculation of body surface area, and 14 required a calculation of dose per square metre of body surface area. Only a third of centres requested patients' written informed consent when oral chemotherapy was given off protocol. Nearly a quarter (10) of centres had no formal process for monitoring patients' adherence. In the past year respondents at 10 centres reported at least one serious adverse drug event related to oral chemotherapy, and respondents at 13 centres reported a serious near miss. Conclusion Few of the safeguards routinely used for infusion chemotherapy have been adopted for oral chemotherapy at US cancer centres. There is currently no consensus at these centres about safe medication practices for oral chemotherapy. PMID:17223629

    KNMI is the Dutch institute for weather, climate research and seismology. It disseminates weather information to the public at large, the government, aviation and the shipping industry in the interest of safety, the economy and a sustainable environment. To gain insight into long-term developments KNMI conducts research on climate change. Making the knowledge, data and information on hand at KNMI accessible is one core activity. A huge part of the KNMI information is from numerical models, insitu sensor networks and remote sensing satellites. This digital collection is mostly internal only available and is a collection of non searchable , non standardized file formats, lacking documentation and has no references to scientific publications. With the KNMI Data Centre (KDC) project these issues are tackled. In the project a user driven development approach with SCRUM was chosen to get maximum user involvement in a relative short development timeframe. Building on open standards and proven open source technology (which includes in-house developed software like ADAGUC WMS and Portal) resulted in a first release in December 2012 This presentation will focus on the aspects of KDC relating to its technical challenges, the development strategy and the initial usage results of the data centre.

    The Sofia University GNSS Analysis Centre (SUGAC, suada.phys.uni-sofia.bg) is a new analysis centre established via collaboration between the Department of Meteorology and Geophysics of Sofia University, the IPOS - BuliPOS GNSS network in Bulgaria and the University of Luxembourg. In April 2014, the first processing campaign took place. One year GNSS data from 7 stations of the BuliPOS network are processed in collaboration with the University of Luxembourg. Tropospheric products (Zenith Total Delay and gradients) with 5 min temporal resolution are obtained using the NAPEOS software, developed by ESA. The tropospheric products from this campaign will be used for validation of the Weather Research and Forecasting (WRF) model as well as for case studies during intense precipitation events and fog. In this work the WRF model validation for Bulgaria will be presented. Future work will be the establishment of autonomous near real-time processing of the regional ground-based GNSS network in Southeast Europe in support of the EUMETNET E-GVAP and COST ES1206 "Advanced Global Navigation Satellite Systems for Severe Weather Events and Climate" projects.

The MCP and solenoid are critical components for producing the toroidal field and for the limited Ohmic flux in STs. Constraints for a ST reactor related to these limitations lead to a minimum plasma aspect ratio of 1.4 which reduces the benefit of operation at higher betas in a more compact ST reactor. Replacing the MCP is of great interest for reactor-based ST studies since the device is simplified, compactness increased, and maintenance reduced. An experiment to show the feasibility of using a plasma centre-post (PCP) is being currently under construction and involves a high level of complexity. A preliminary study of a very simple PCP, which is ECR(Electron Cyclotron Resonance)-assisted and which includes an innovative fuelling system based on pellet injection, has recently been reported. This is highly suitable for an ultra-low aspect ratio tokamak (ULART) device. Advances on this PCP ECR-assisted concept within a ULART and the associated fuelling system are presented here, and will include the field topology for the PCP ECR-assisted scheme, pellet ablation modeling, and a possible global equilibrium simulation.

    AUTOSUB-2, an autonomous underwater vehicle (AUV) developed by the Southampton Oceanography Centre, was used for high resolution hydrographic surveys in the Sicily Strait. A combination of “seasoar” type profiling and terrain following missions were undertaken and velocity and hydrographic measurements taken from AUTOSUB-2 were compared with concurrent shipboard hydrographic and velocity profiles. Even though shipboard stations were separated by just 5 to 8 km along the mission path, data from the AUV showed small scale variability that was missed by the shipboard sampling. In this paper we present the example of an intense jet, with maximum speed greater than 0.50 m s-1, less than 4 km wide.

    The relative position of lunar center masses relative to center of the figure in Kazan and Kiev selenocentric catalogues was customized. The expansions by spherical harmonics N=5 degree and order of the lunar function h(λ, β) with using the package ASNI USTU were executed. Module of the expansion of the local area to surfaces to full sphere was used. The parameters of cosmic missions are given for comparison (SAI; Bills, Ferrari). The normalized coefficients from expansions for eight sources hypsometric information are obtained: - Clementine (N=40), - Kazan (N=5), - Kiev (N=5), - SAI (N=10; Chuikova (1975)), - Bills, Ferrari, - Каguуа (Selena, Japan mission), - ULCN (The Uuified Lunaz Control Network 2005). The displacements of the lunar centre figure relative to lunar centre of the masses were defined from equations (Chuikova (1975)). The results of the obtaining relative position of the lunar centre masses and centre of the figure in Kazan selenocentric catalogue give good agreement with modern cosmic mission data.

    The original intention for this work was to impart the technology that was developed in the field of computational aeronautics to the field of computational physical oceanography. This technology transfer involved grid generation techniques and solution procedures to solve the governing equations over the grids thus generated. Specifically, boundary fitting non-orthogonal grids would be generated over a sphere taking into account the topography of the ocean floor and the topography of the continents. The solution methodology to be employed involved the application of an upwind, finite volume discretization procedure that uses higher order numerical fluxes at the cell faces to discretize the governing equations and an implicit Newton relaxation technique to solve the discretized equations. This report summarizes the efforts put forth during the past three years to achieve these goals and indicates the future direction of this work as it is still an ongoing effort.

    This project centers around the Strategic Petroleum Site (SPR) known as the West Hackberry salt dome which is located in southwestern Louisiana, and which is designed to store 241 million barrels of crude oil. Oil storage caverns are formed by injecting water into salt deposits, and pumping out the resulting brine. Studies described in this report were designed as follow-on studies to three months of pre-discharge characterization work, and include data collected during the first year of brine leaching operations. The objectives were to: (1) characterize the environment in terms of physical, chemical and biological attributes; (2) determine if significant adverse changes in ecosystem productivity and stability of the biological community are occurring as a result of brine discharge; and (3) determine the magnitude of any change observed. Contents of Volume II include: introduction; physical oceanography; estuarine hydrology and hydrography; analysis of discharge plume; and water and sediment quality.

  14. Twin Jets from the Centres of Galaxies

    Kundt, W.; Gopal-Krishna

    1981-04-01

    Conceivably, the centres of all massive galaxies emit continuous antipodal beams of relativistic particles. We shall argue that these beams consist of highly relativistic electrons and positrons. At formation, the beams plough a channel through the ambient medium; the swept-up matter repeatedly stalls the particles which thereby follow closely the ambient pressure gradient. Thereafter, when the relativistic beam particles traverse these swarms of swept-up filamentary matter, they are repeatedly forced to bypass individual filaments and radiate (in the direction of their instantaneous motion). This forward-peaked radiation pattern can explain the preferred one-sided-ness of the observed radio/optical/X-ray knots in the jets. Pressure confinement focusses the beams, and temporarily freezes the channels. Interaction with the intergalactic wind can bend the beams into the shape of a warpedU, on length scales above some 20 kpc. The observed morphologies of extragalactic radio sources find a common explanation.

    A middle aged woman presented to an Ebola Treatment Centre in West Africa with a 4-day history of fever, fatigue, joint pain and vomiting. She tested positive for Ebola virus disease (EVD) and a standard treatment platform of care was started. On day 3 of her admission, she was found to have suffered a left-sided CVA of unknown aetiology. Treatment was largely supportive within a resource-constrained environment and the added layer of providing care with extensive personal protective equipment, and human resource and safety constraints. The patient was able to clear the EVD and did regain some functional use of her arm and leg. She was discharged on day 15 of her stay, as a survivor of both stroke and Ebola. PMID:26516244

    "There are only two ways to life your live. One is as though nothing is a miracle. The other is as though everything is a miracle." Albert Einstein Children's Centre "3 in 1" is an extracurricular unit linked to the High School of Zlatartitsa, St. Cyril and St. Methodius, accomplished with the help of the municipality and many volunteers from the local community. With its activity it forms in children patriotic spirit, love for nature, active citizenship, and an impulse for a healthy life through communication with nature, saving the traditions and history, insurance of equality of the kids of the local five ethnicities and participation in activities in the sphere of science, art, sport and tourism. The educational work is mainly directed towards kids with difficulties with communication, hyperactivity, aggression, problems in their families, or those deprived of parental care. For a few years in the Children's Centre there have been clubs of interests: "Gardeners" - kids cultivate a garden. They plow, dig, plant, put in, irrigate and weed under the watch of Ms Stafka Nikolova, parents, and volunteers of the local community. The ecologically clean products - vegetables and fruits, kids use to cook delicious meals, sell, or give away. Weeds are also utilized; they are making herbarium out of them. "Cooks" - "What to have for lunch, when mom is out?". One can learn a lot of wonderful recipes from the club "Cooks". Products are own made, raised with love. In 2010, on the on the annual traditional holiday of the garden soup in Zlataritsa, the little cooks won third prize for making a delicious vegetable soup. On the same day, the 26 years old Nadezhda Savova, Cultural and Social Anthropology PhD in Princeton, founded the second community bakery in Bulgaria in Children's Centre "3 in1". Nadezhda Savova was declared traveler of 2012 by National Geographic. After the baking house in Gabrovo and Zlataritsa, Nadezhda also founded such projects in Sofia, Varna and Ruse. Today there are baking houses in 13 countries on 3 continents - Israel, Palestine, Brazil, Italy, Peru, Egypt, South Africa, South Korea, the USA, Romania, Russia and Japan. The idea of making bread destroys any differences and brings people together. We are all crumbs of the common bread. "Historians" - "History is useful not because we read the past in it, but the future" - J.B.Say. The young historians explore the past of their homeland. They write down the memories of eyewitnesses of some important events in the community. The most impressive for the kids are the memories of the people about the gardeners of old time and the flood of 1943 in Zlataritsa. This involves the heroism of the people for saving their fellow citizens and the reconstruction of the damages. This all told by the coeval Vasil Uzunov. The activity in the center is documented in a register written by the kids and popularizes this form of media. In the centre every child finds itself and appreciates the opportunities for self-expression and team work, builds a positive attitude to its own personality and the personality of the one next to him. A kid there reveals its creativity, realizes the unity of diversity, forms a positive and a responsible attitude to the nature, rationalize universal values, makes friends, and feels useful and significant. The most wonderful thing in a friendship is not when somebody gives you help or smile or a good companion, but when both inspire for life, which we receive when we know that somebody believes in us. Do not search for strength and confidence out of yourself, because they're inside you. They were always there.

  17. At the centre: influenza A virus ribonucleoproteins.

    2015-01-01

    Influenza A viral ribonucleoprotein (vRNP) complexes comprise the eight genomic negative-sense RNAs, each of which is bound to multiple copies of the vRNP and a trimeric viral polymerase complex. The influenza virus life cycle centres on the vRNPs, which in turn rely on host cellular processes to carry out functions that are necessary for the successful completion of the virus life cycle. In this Review, we discuss our current knowledge about vRNP trafficking within host cells and the function of these complexes in the context of the virus life cycle, highlighting how structure contributes to function and the crucial interactions with host cell pathways, as well as on the information gaps that remain. An improved understanding of how vRNPs use host cell pathways is essential to identify mechanisms of virus pathogenicity, host adaptation and, ultimately, new targets for antiviral intervention.

    We studied communal roosting in the Common Myna (Acridotheres tristis) in the light of the recruitment centre hypothesis and predation at the roost. The number and sizes of flocks departing from and arriving at focal roosts were recorded over a two year period. We also recorded the sizes and behaviour of foraging flocks. We found that flock sizes of birds departing from roosts at sunrise were larger than those at the feeding site, suggesting that there was no recruitment from the roosts. Flocks entering the roosts during sunset were larger on average than those leaving the following sunrise, suggesting no consolidation of flocks in the morning. Flocks entering the roosts at sunset were also larger on average than those that had left that sunrise, although there was no recruitment at the feeding site. There was no effect of group size on the proportion of time spent feeding. Contrary to expectation, single birds showed lower apparent vigilance than birds that foraged in pairs or groups, possibly due to scrounging tactics being used in the presence of feeding companions. Thus, the recruitment centre hypothesis did not hold in our study population of mynas. Predation at dawn and dusk were also not important to communal roosting: predators near the roosts did not result in larger flocks, and resulted in larger durations of arrival/departure contrary to expectation. Since flock sizes were smallest at the feeding site and larger in the evening than in the morning, but did not coincide with predator activity, information transfer unrelated to food (such as breeding opportunities) may possibly give rise to the evening aggregations.

  19. Distant Operational Care Centre: Design Project Report

    1996-01-01

    The goal of this project is to outline the design of the Distant Operational Care Centre (DOCC), a modular medical facility to maintain human health and performance in space, that is adaptable to a range of remote human habitats. The purpose of this project is to outline a design, not to go into a complete technical specification of a medical facility for space. This project involves a process to produce a concise set of requirements, addressing the fundamental problems and issues regarding all aspects of a space medical facility for the future. The ideas presented here are at a high level, based on existing, researched, and hypothetical technologies. Given the long development times for space exploration, the outlined concepts from this project embodies a collection of identified problems, and corresponding proposed solutions and ideas, ready to contribute to future space exploration efforts. In order to provide a solid extrapolation and speculation in the context of the future of space medicine, the extent of this project's vision is roughly within the next two decades. The Distant Operational Care Centre (DOCC) is a modular medical facility for space. That is, its function is to maintain human health and performance in space environments, through prevention, diagnosis, and treatment. Furthermore, the DOCC must be adaptable to meet the environmental requirements of different remote human habitats, and support a high quality of human performance. To meet a diverse range of remote human habitats, the DOCC concentrates on a core medical capability that can then be adapted. Adaptation would make use of the DOCC's functional modularity, providing the ability to replace, add, and modify core functions of the DOCC by updating hardware, operations, and procedures. Some of the challenges to be addressed by this project include what constitutes the core medical capability in terms of hardware, operations, and procedures, and how DOCC can be adapted to different remote habitats.

    In the framework of the peculiar motivation of this conference to pay a tribute to Pierre Léna, we draw a parallel between the evolution of our knowledge on the Galactic Centre and the developments of infrared and high resolution techniques. We first recount the 1st French observations of the Galactic Centre with infrared arrays. The 2nd section is dedicated to the 1st adaptive optics observations of the Galactic Centre. We then remind the results obtained from adaptive optics imaging (3rdsection) and integral field spectroscopy (4th section) observations of the Galactic Centre. After comparing the image quality for Galactic Centre observations with laser guide star, infrared wavefront sensor and visible wavefront sensor adaptive optics (5th section), we introduce in the 6th section two future instruments that will be extensively used for future Galactic Centre studies: Gravity and ELTs.

    LiF crystals with colour centres exhibiting a zero-phonon line (ZPL) at 1080 nm in absorption and luminescence are studied. The decay time of luminescence of colour centres at 10 K is 260 - 280 ns, the ZPL half-width is 4.7 cm{sup -1}, and colour centres are characterised by a weak electron - phonon interaction (the Huang - Rhys factor is S < 0.11). The polarisation analysis of luminescence showed that the transition dipole moments of colour centres are oriented along the crystal axes [100], [010], and [001]. The model of aggregate F{sub 4} colour centres having a spatial structure with three symmetry axes C{sub 2} may correspond to the colour centres studied in the paper. (active media. lasers)

  5. A SDMS Model: Early Warning Coordination Centres

    NASA Astrophysics Data System (ADS)

    Santos-Reyes, Jaime

    2010-05-01

    Following the tsunami disaster in 2004, the General Secretary of the United Nations (UN) Kofi Annan called for a global early warning system for all hazards and for all communities. He also requested the ISDR (International Strategy fort Disaster Reduction) and its UN partners to conduct a global survey of capacities, gaps and opportunities in relation to early warning systems. The produced report, "Global survey of Early Warning Systems", concluded that there are many gaps and shortcomings and that much progress has been made on early warning systems and great capabilities are available around the world. However, it may be argued that an early warning system (EWS) may not be enough to prevent fatalities due to a natural hazard; i.e., it should be seen as part of a ‘wider' or total system. Furthermore, an EWS may work very well when assessed individually but it is not clear whether it will contribute to accomplish the purpose of the ‘total disaster management system'; i.e., to prevent fatalities. For instance, a regional EWS may only work if it is well co-ordinated with the local warning and emergency response systems that ensure that the warning is received, communicated and acted upon by the potentially affected communities. It may be argued that without these local measures being in place, a regional EWS will have little impact in saving lives. Researchers argued that unless people are warned in remote areas, the technology is useless; for instance McGuire [5] argues that: "I have no doubt that the technical element of the warning system will work very well,"…"But there has to be an effective and efficient communications cascade from the warning centre to the fisherman on the beach and his family and the bar owners." Similarly, McFadden [6] states that: "There's no point in spending all the money on a fancy monitoring and a fancy analysis system unless we can make sure the infrastructure for the broadcast system is there,"… "That's going to require a lot of work. If it's a tsunami, you've got to get it down to the last Joe on the beach. This is the stuff that is really very hard." Given the above, the paper argues that there is a need for a systemic approach to early warning centres. Systemic means looking upon things as a system; systemic means seeing pattern and inter-relationship within a complex whole; i.e., to see events as products of the working of a system. System may be defined as a whole which is made of parts and relationships. Given this, ‘failure' may be seen as the product of a system and, within that, see death/injury/property loss etc. as results of the working of systems. This paper proposes a preliminary model of ‘early warning coordination centres' (EWCC); it should be highlighted that an EWCC is a subsystem of the Systemic Disaster Management System (SDMS) model.

    ACTRIS (Aerosols, Clouds, and Trace gases Research InfraStructure Network) is a European Project aiming at integrating European ground-based stations equipped with advanced instrumentation for studying aerosols, clouds, and short-lived gas-phase species. The ACTRIS activities result in improved atmospheric measurements data made at more than 60 European sites, from numerous instruments and includes variables measured by ground based in situ and remote sensing technologies. Core variables are in situ aerosol optical, physical and chemical properties, short-lived trace gases (volatile organic carbon and nitrogen oxides), aerosol scattering and extinction profiles, and cloud properties. The ACTRIS data centre (ACTRIS DC) is giving free and open access to all data resulting from the activities of the infrastructure network, complemented with data from other relevant networks and data bases. The overall goal is to facilitate scientists and other user groups access to atmospheric observational data, and to provide mature products for analysis and interpretation of atmospheric composition change. The ACTRIS DC aims at substantially increasing the number of high-quality data by providing long-term observational data relevant to climate and air quality research produced with standardized or comparable procedures throughout the network. The backbone of the ACTRIS DC is the three core data bases: - EARLINET Data Base hosting aerosol lidar data from more than 30 European sites - EBAS hosting ground based atmospheric in situ data from more than 1000 sites globally - Cloudnet hosting remote sensing cloud data and products from 5 European sites Furthermore, a joint portal is developed combining information from various data sources to gain new information not presently available from standalone databases or networks. The data centre will provide tools and services to facilitate the use of measurements for broad user communities. Higher level and integrated products will be developed stage-by-stage during the project, and user requirements, interactions and feedbacks are essential. The first version of ACTRIS DC is a web portal that allows users to search for atmospheric composition data from a multitude of data archives through a single user interface. Examples of data bases and frameworks included are EMEP, the GAW- world data centres, EARLINET, NDACC, CARIBIC-GEOmon, HTAP, AMAP amongst others. Currently the portal provides an overview of more than 800 000 data sets from more than 20 data bases/frameworks globally. For some of the databases included in the portal, the interface furthermore allows you to download data directly through the portal. A map functionality is implemented facilitating the identification of data and making it possible to search for collocation of observations, variables and sites both in time and space. The data portal can serve as "one-stop-shop" of atmospheric high-quality data, and the portal will also offer a direct interface towards external users like the MACC II project and GMES in-situ. The data dissemination will take into account the principles outlined in SEIS, INSPIRE, WIS and GEOSS.

    Background: Although prior studies have suggested an inverse association between liver transplant centre volume and postoperative patient mortality, more recent analyses have failed to confirm this association. To date, all studies of the relationship between centre volume and outcomes in liver transplantation have been cross-sectional in design. Objective: The objective of our study was to examine temporal trends in the volume–outcomes relationship for liver transplantation. Methods: We used information obtained from the Scientific Registry of Transplant Recipients (SRTR) programme-specific data reports to examine the outcomes of adult liver transplant recipients stratified by annual centre volume. This relationship between centre volume and patient outcomes was assessed over three consecutive time periods from 2000 through 2007. Results: The overall 25% increase in adult liver transplant volume in the USA from 2000 to 2007 appeared to be distributed fairly equally among existing transplant centres. In the earliest time period of our analysis, high-volume centres achieved superior risk-adjusted 1-year patient outcomes compared with low-volume centres. By the third and most recent time period of the analysis, this discrepancy between the outcomes of high- and low-volume centres was no longer statistically apparent. Conclusions: The relationship between centre volume and patient outcomes for liver transplantation in the USA has become less pronounced over time, suggesting that the use of procedure volume as a marker of liver transplant centre quality cannot be justified. The performance-based review process currently utilized in the USA may have contributed to this diminishing influence of centre volume on liver transplant recipient outcomes. This type of review process should be considered as a potential alternative to the volume-based referral initiatives that have been developed for other non-transplant, complex surgical procedures.

  8. Radio polarimetry of Galactic centre pulsars

    To study the strength and structure of the magnetic field in the Galactic centre (GC) we measured Faraday rotation of the radio emission of pulsars which are seen towards the GC. Three of these pulsars have the largest rotation measures (RMs) observed in any Galactic object with the exception of Sgr A⋆. Their large dispersion measures, RMs and the large RM variation between these pulsars and other known objects in the GC implies that the pulsars lie in the GC and are not merely seen in projection towards the GC. The large RMs of these pulsars indicate large line-of-sight magnetic field components between ˜ 16 - 33 μG; combined with recent model predictions for the strength of the magnetic field in the GC this implies that the large-scale magnetic field has a very small inclination angle with respect to the plane of the sky (˜ 12°). Foreground objects like the Radio Arc or possibly an ablated, ionized halo around the molecular cloud G0.11-0.11 could contribute to the large RMs of two of the pulsars. If these pulsars lie behind the Radio Arc or G0.11-0.11 then this proves that low-scattering corridors with lengths ≳ 100 pc must exist in the GC. This also suggests that future, sensitive observations will be able to detect additional pulsars in the GC. Finally, we show that the GC component in our most accurate electron density model oversimplifies structure in the GC.

    We treat, as an illustrative example of gravitational time dilation in relativity, the observation that the centre of the Earth is younger than the surface by an appreciable amount. Richard Feynman first made this insightful point and presented an estimate of the size of the effect in a talk; a transcription was later published in which the time difference is quoted as ‘one or two days’. However, a back-of-the-envelope calculation shows that the result is in fact a few years. In this paper we present this estimate alongside a more elaborate analysis yielding a difference of two and a half years. The aim is to provide a fairly complete solution to the relativity of the ‘aging’ of an object due to differences in the gravitational potential. This solution—accessible at the undergraduate level—can be used for educational purposes, as an example in the classroom. Finally, we also briefly discuss why exchanging ‘years’ for ‘days’—which in retrospect is a quite simple, but significant, mistake—has been repeated seemingly uncritically, albeit in a few cases only. The pedagogical value of this discussion is to show students that any number or observation, no matter who brought it forward, must be critically examined.

  10. Ensemble Prediction at the Canadian Meteorological Centre

    2004-05-01

    A global ensemble prediction system (EPS) is running operationally at the Canadian Meteorological Centre (CMC) since February 1998. The number of members was increased from 8 to 16 members in august 1999 and the resolution was increased from 250km to 150km in June 2001. A multi-model approach is used to produce 10 day forecasts once a day. The Spectral Finite Element model (SEF) is used at TL149 and the Global Environment Multi-scale (GEM) model is used at the equivalent 1.2 degree resolution. The initial analyses are produced from an Optimal Interpolation (OI) technique developed at CMC in the early seventies is currently being replaced by an Ensemble Kalman Filter approach developed by Houtekamer and Mitchell. We will describe the new method to obtain the perturbed analyses using the Ensemble Kalman Filter and the verifications obtained to phase out the old OI technique. The ensemble approach is a natural tool to forecast the probability of precipitation (POP). Classes can be defined for different thresholds of 2, 5, 10 and 25 mm of precipitation of 24 hour periods. Improving the resolution of the EPS models has resulted in improvement of the POP over Canadian stations. Results of this evaluation as compared to the operational deterministic model will be shown.

    This is a review of the facilities and programmes of the Finnish National Centre for Emergency Services in Kuopio, Finland. It includes the Emergency Services College that provides all of the training for emergency service workers in Finland and provides some services for the international community. There are needs for training by the medical community in Finland that relate both to skills and knowledge. Education and training focus on the demonstration of evidence-based competence. The facility includes a training ground for the provision of immediate emergency medical care, scene safety, extrication, industrial accidents, and water rescue. It is used for the training of paramedic students, nurses, medical students, firefighters, dispatch center staff, and officers. Computer-aided simulations are used to enhance the learning process. Plans are underway for adding tele-education and/or virtual-reality facilities. Close liaison is maintained with the University of Kuopio, Kuopio University Hospital, and with the Pohjois-Savo Polytechnic Institute. PMID:11183458

    Children's centres were established across England to provide a range of services including early education, social care and health to pre-school children and their families. We surveyed children's centres to ascertain the activities they were undertaking to prevent unintentional injuries in the under fives. A postal questionnaire was sent to a sample of children's centre managers (n = 694). It included questions on current activities, knowledge and attitudes to injury prevention, health priorities and partnership working. Responses were received from 384 (56%) children's centres. Overall, 58% considered unintentional injury prevention to be one of the three main child health priorities for their centre. Over half the respondents (59%) did not know if there was an injury prevention group in their area, and 21% did not know if there was a home safety equipment scheme. Knowledge of how child injury deaths occur in the home was poor. Only 11% knew the major cause of injury deaths in children under five. Lack of both staff time and funding were seen as important barriers by children's centre staff to undertake injury prevention activities. Nearly all stated that training (97%) and assistance with planning injury prevention (94%) would be helpful to their centres. Children's centres need further support if they are to effectively tackle this important public health area. PMID:23837887

  15. Reducing cooling energy consumption in data centres and critical facilities

    NASA Astrophysics Data System (ADS)

    Cross, Gareth

    Given the rise of our everyday reliance on computers in all walks of life, from checking the train times to paying our credit card bills online, the need for computational power is ever increasing. Other than the ever-increasing performance of home Personal Computers (PC's) this reliance has given rise to a new phenomenon in the last 10 years ago. The data centre. Data centres contain vast arrays of IT cabinets loaded with servers that perform millions of computational equations every second. It is these data centres that allow us to continue with our reliance on the internet and the PC. As more and more data centres become necessary due to the increase in computing processing power required for the everyday activities we all take for granted so the energy consumed by these data centres rises. Not only are more and more data centres being constructed daily, but operators are also looking at ways to squeeze more processing from their existing data centres. This in turn leads to greater heat outputs and therefore requires more cooling. Cooling data centres requires a sizeable energy input, indeed to many megawatts per data centre site. Given the large amounts of money dependant on the successful operation of data centres, in particular for data centres operated by financial institutions, the onus is predominantly on ensuring the data centres operate with no technical glitches rather than in an energy conscious fashion. This report aims to investigate the ways and means of reducing energy consumption within data centres without compromising the technology the data centres are designed to house. As well as discussing the individual merits of the technologies and their implementation technical calculations will be undertaken where necessary to determine the levels of energy saving, if any, from each proposal. To enable comparison between each proposal any design calculations within this report will be undertaken against a notional data facility. This data facility will nominally be considered to require 1000 kW. Refer to Section 2.1 'Outline of Notional data Facility for Calculation Purposes' for details of the design conditions and constraints of the energy consumption calculations.

  16. Influence of the rotation centre in panoramic radiography.

    Kaeppler, G; Buchgeister, M; Reinert, S

    2008-01-01

    The aim is to present the curve of the rotation centre in dental panoramic radiography and to examine its influence on organ doses. A screenless film was fixed between the layers of an Alderson Rando phantom in the centre of the mandible. The phantom was positioned in two different X-ray units [Scanora (Soredex, Helsinki, Finland) and Orthophos (Sirona, Bensheim, Germany)] and exposed. Organ doses and effective doses were determined. The curves of the rotation centre showed clear differences especially in the area of the parotid gland. These differences corresponded to the differences in organ doses and in effective doses (Scanora: 29.9 microGy; Orthophos Plus: 14 microGy). Artefacts might be shown (Orthophos, result of a plate osteosynthesis) or not (Scanora) due to the different rotation centres. Differences in organ doses and in image quality, e.g. artefacts, were explained with the curve of the rotation centre and beam geometry. PMID:17573368

  17. The "magic" of tutorial centres in Hong Kong: An analysis of media marketing and pedagogy in a tutorial centre

    NASA Astrophysics Data System (ADS)

    Koh, Aaron

    2014-12-01

    Why do more than three-quarters of Hong Kong's senior secondary students flock to tutorial centres like moths to light? What is the "magic" that is driving the popularity of the tutorial centre enterprise? Indeed, looking at the ongoing boom of tutorial centres in Hong Kong (there are almost 1,000 of them), it is difficult not to ask these questions. This paper examines the phenomenon of tutorial centres in Hong Kong and seeks to understand what draws students to these centres. Combining theories of marketing semiotics and emotion studies, the author investigates the pivotal role of media marketing in generating the "magic" of tutorial centres, whose advertising strategy includes, for example, a display of billboard posters featuring stylishly-dressed "celebrity teachers". The author reviews some of the literature available on the subject of tutorial centres. In a case study approach, he then maps out the pedagogy he observed in an English tutorial class, seeking heuristic insights into the kind of teaching students in the study were looking for. He argues that part of the "magical" attraction of what are essentially "cram schools" is their formulaic pedagogy of teaching and reinforcing exam skills. Finally, the paper considers the social implications of the tutorial centre industry in terms of media marketing of education and unequal access to tutorial services.

  1. Hillary Clinton impressed by the Centre's work.

    PubMed

    1995-01-01

    In April 1994, US First Lady Hillary Rodham Clinton, her daughter Chelsea, the Bangladesh Minister for Women and Children's Affairs, and the US Ambassador to Bangladesh visited the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B). The First Lady remarked that ICDDR,B's research programs on health and family planning have many important lessons for the developing and developed regions alike. She noted the development successes in Bangladesh that can be applied in the US and other countries: the Grameen Bank, oral rehydration solution (ORS), and the community outreach programs for health and family planning services. The First Lady was especially interested in ORS and its cost-effectiveness. Most of the 220,000 children hospitalized each year in the US for severe gastrointestinal illness are treated with expensive intravenous (IV) drips (average cost = $2300), while a few ORS packets would be a small fraction of the cost. The average cost of treatment per patient at ICDDR,B was only $12. Patients receive care free of charge. Less than 0.6% of the patients die. The previous year, a USAID administrator asked ICDDR,B for its expertise in fighting cholera at the Rwandan refugee camps in Goma, Zaire. ICDDR,B staff developed diagnostic antisera for the new cholera strain responsible for the epidemic in the Americas, described its pathophysiology, and established its mode of transmission in surface waters. ICDDR,B also provides technical support to the national family planning and maternal and child health programs. In the Matlab, ICDDR,B's work has contributed to a high contraceptive prevalence rate of more than 64% among poor and largely illiterate persons. PMID:12289844

  2. Analysis procedures at the International Seismological Centre

    NASA Astrophysics Data System (ADS)

    Adams, R. D.; Hughes, A. A.; McGregor, D. M.

    1982-11-01

    Analysis at the International Seismological Centre (ISC) falls into three main categoriesassociation, location and quantification. Difficulties of association on a global scale are not always appreciated. The ISC currently analyses 40-50 events a day, and as the first arrivals from any particular earthquake may span a time interval of up to 20 min, readings from events occurring in different parts of the world may overlap considerably in time. The present association algorithm depends on time only, and results in many chance mis-associations, or even the synthesis of fictitious events. At present, these mis-associations are rectified by seismologists' intervention, but full use of amplitude and period information could help to detect these errors automatically. Revision of locations follows standard least-squares procedures, based on Jeffrey's method of uniform reduction and Jeffreys-Bullen travel times. Locations are made from P phases only (including crustal phases), but other first arrivals and secondary phases are identified and residuals calculated. If depth cannot be determined by geometric means a search is made for depth phases, or failing this, the depth is restrained to that given by another agency, or to a conventional value. No provision is made for local variations in travel time. Body-wave magnitudes are allocated within the distance range 21-100 from reported readings of A and T, or their ratio, using Gutenberg-Richter calibration curves. Surface-wave magnitudes are calculated from the "Prague" formula, using reports of long-period A and T in the distance range 5-160, but only values from stations at distances of 20 or more are used to determine an average Ms for a particular event. There is no provision for the determination of local magnitude other than to reproduce values assigned by local agencies. Improvements in these procedures could be made through the automatic association of station readings, the introduction of local travel times, and better determination of earthquake size, particularly for local events.

  5. Role of comprehensive cancer centres during economic and disease transition: National Cancer Centre, Singapore--a case study.

    PubMed

    Soo, Khee Chee

    2008-08-01

    In 1999, Singapore created a comprehensive cancer centre because of the rising occurrence of cancer in the country. Although Singapore is different from many developing countries because of its small geographical size and its well-endowed economy, it has issues that are common to any country or community wanting to start such centres. We present our experience of developing a comprehensive cancer centre. We located the cancer centre strategically adjacent to Singapore's largest hospital. Clinics were designed to provide multidisciplinary care, and site-specific radiation, medical, and surgical oncologists could consult with patients on the same day and at the multidisciplinary outpatient clinics. We developed a large research team and ensured that tumour specimens were carefully obtained and annotated in our tissue repository. Furthermore, we are building up a robust cancer informatics system as well as a pipeline of specialists with local training and overseas stints at other top cancer centres. PMID:18672215

  6. Native NIR-emitting single colour centres in CVD diamond

    2014-05-01

    Single-photon sources are a fundamental element for developing quantum technologies, and sources based on colour centres in diamonds are among the most promising candidates. The well-known nitrogen vacancy centres are characterized by several limitations, and thus few other defects have recently been considered. In the present work, we characterize, in detail, native efficient single colour centres emitting in the near infra-red (λ = 740-780 nm) in both standard IIa single-crystal and electronic-grade polycrystalline commercial chemical vapour deposited (CVD) diamond samples. In the former case, a high-temperature (T > 1000 °C) annealing process in vacuum is necessary to induce the formation/activation of luminescent centres with good emission properties, while in the latter case the annealing process has marginally beneficial effects on the number and performance of native centres in commercially available samples. Although displaying significant variability in several photo-physical properties (emission wavelength, emission rate instabilities, saturation behaviours), these centres generally display appealing photophysical properties for applications as single photon sources: short lifetimes (0.7-3 ns), high emission rates (˜50-500 × 103 photons s-1) and strongly (>95%) polarized light. The native centres are tentatively attributed to impurities incorporated in the diamond crystal during the CVD growth of high-quality type-IIa samples, and offer promising perspectives in diamond-based photonics.

    Today, the extensive numerical simulations of climate models require elaborate visualization for understanding and communicating the results. Typical data sets of climate models are 3-dimensional, multivariate and time dependent, and can hence be very large. Interactive visual data analysis improves and accelerates the comprehension of these vast amounts of data. At DKRZ, the German Climate Computing Centre, a central high end visualization server, various domain specific visualization applications, and a remote 3D rendering solution enable users to interactively visualize their extensive model results right at their desktops. The DKRZ's visualization server is a heterogeneous Linux cluster, currently consisting of 10 state of the art visualization nodes equipped with 96 -256 GB RAM and high end NVidia GPUs. Since the parallel file system of the DKRZ's supercomputer is directly mounted over a powerful network, the model data can directly be analyzed and visualized. VirtualGL and TurboVNC are used for utilizing the server's GPUs for 3D rendering, while the TurboVNC client on the user's local computer continuously displays the resulting video stream. By using this central visualization server instead of a local computer, three main benefits are achieved: Time consuming transfers of large data sets from the supercomputer to the local computer are not needed. The hardware of the user's local workstation doesn't need to be powerful, no expensive GPU is required. Users don't have to install or buy visualization software. On the visualization server, a wide range of visualization software is installed. Avizo Green, a powerful commercial software customized for interactive 3D visualization of climate model data, is available, as well as SimVis and ParaView, which focus more on an exploratory visualization of data. SimVis and ParaView provide techniques like Linking & Brushing to emphasize or de-emphasize portions of the data. Furthermore, some domain specific 2D graphics software packages, like NCL and GrADS, as well as software for processing, manipulating and analyzing the data, such as the CDOs (Climate Data Operators), are also used on the DKRZ visualization server. This PICO will give an overview on the overall system and the techniques applied at DKRZ for the visualization of climate modeling results. Many examples are given to illustrate the types of applications.

    Planetary exploration by means of radar systems, mainly using GPRs is an important role of Italy and numerous scientific international space programs are carried out jointly with ESA and NASA by Italian Space Agency, the scientific community and the industry. Three experiments under Italian leadership ( designed and manufactured by the Italian industry) provided by ASI within a NASA/ESA/ASI joint venture framework are successfully operating: MARSIS on-board MEX, SHARAD on-board MRO and CASSINI Radar on-board Cassini spacecraft: the missions have been further extended . Three dedicated operational centers, namely SHOC, (Sharad Operating Centre), MOC (Marsis Operating Center) and CASSINI PAD are operating from the missions beginning to support all the scientific communities, institutional customers and experiment teams operation Each center is dedicated to a single instrument management and control, data processing and distribution and even if they had been conceived to operate autonomously and independently one from each other, synergies and overlaps have been envisaged leading to the suggestion of a unified center, the Planetary Radar Processing Center (PROC). In order to harmonize operations either from logistics point of view and from HW/SW capabilities point of view PROC is designed and developed for offering improved functionalities to increase capabilities, mainly in terms of data exchange, comparison, interpretation and exploitation. PROC is, therefore, conceived as the Italian support facility to the scientific community for on-going and future Italian planetary exploration programs, such as Europa-Jupiter System Mission (EJSM) The paper describes how the new PROC is designed and developed, to allow SHOC, MOC and CASSINI PAD to operate as before, and to offer improved functionalities to increase capabilities, mainly in terms of data exchange, comparison, interpretation and exploitation aiding scientists to increase their knowledge in the field of surface radar sounding: furthermore the flexibility and the big dimensions of the PROC archives allow easy integration of other missions (e.g. EJSM). A specific PROC Web facility and a dedicated high capacity on line storage allow PROC missions status and scientific results spreading, scientific requests submission, news, studies, technical information, radar data images publication and data retrieving (the latter only on science team members request), according to different permissions assigned both to science team members and generic users

    2005-01-01

    We briefly present the modes of functioning of Diabetes Convention Centres in Belgium. In those hospital centres, patients with both type 1 or type 2 diabetes, treated by at least two insulin injections per day, benefit of an intensive educational programme by a multidisciplinary team and receive free of charge material for home blood glucose monitoring, in order to optimize diabetes management. The collaboration between convention centres and general practitioners should be reinforced (share-care), especially to improve the management of type 2 diabetic patients, who are increasingly treated with various insulin regimens.

    Heroin-assisted treatment (HAT) is a solution for improving the condition of treatment-resistant heroin addicts. Since 1994, six randomized controlled trials have concluded that HAT is more efficacious than oral methadone for severe heroin addicts. We visited seven HAT treatment centres in four countries in order to observe diacetylmorphine (DAM) administration and to study the main concerns of the staff. Nurses were concerned by the risk taken if a previously intoxicated patient received his dose of DAM. Another concern was the smuggling of DAM doses. The HAT centres face a dilemma: treating patients while at the same time allowing their risky street habits in the centre. PMID:22074590

    This article describes a theory-driven evaluation of one component of an intervention to improve the quality of health care at Ugandan public health centres. Patient-centred services have been advocated widely, but such approaches have received little attention in Africa. A cluster randomized trial is evaluating population-level outcomes of an intervention with multiple components, including ‘patient-centred services.’ A process evaluation was designed within this trial to articulate and evaluate the implementation and programme theories of the intervention. This article evaluates one hypothesized mechanism of change within the programme theory: the impact of the Patient Centred Services component on health-worker communication. The theory-driven approach extended to evaluation of the outcome measures. The study found that the proximal outcome of patient-centred communication was rated 10 percent higher (p < 0.008) by care seekers consulting with the health workers who were at the intervention health centres compared with those at control health centres. This finding will strengthen interpretation of more distal trial outcomes. PMID:25983612

    In six months there were 1,704 attendances at the treatment room of a small health centre. The attendance rate for the population registered with the health centre doctors was 448 per 1,000 patients per year. Females between 15 and 44 years and males under 15 had the highest attendance rates. There were 256 casual attenders, 58 (23%) of whom were referred to a doctor or hospital for further advice or treatment. It is suggested that in a health centre treatment room about six hours of nursing time a week for every 1,000 patients is required, and that a case can be made out for some of the routine work of casualty departments being done in health centres.

    The call for health-care services that are patient-centred raises the need for knowledge development in both the conceptual and empirical domains. The definitions and operational elements of patient-centred care present a variety of conceptual issues. A common element in all definitions is accommodation of patient wants, preferences, and expectations. In the research domain, intervention studies face both design and measurement challenges. These include the development of interventions that are patient-centred or tailored for both patient characteristics and the environment in which they will be delivered. By addressing these critical issues, nursing can play a key role in advancing intervention science and knowledge development in the domain of patient-centred care. PMID:15551666

    2015-10-14

    There is a plethora of literature on person-centred care and its importance in health care. The principles of person-centred care are especially important for people living with dementia because of the clinical manifestations of the disease. This article intends to provide nurses with an overview of the work of Tom Kitwood and how it pertains to providing best practice in dementia care. Various person-centred theories have been developed. However, Kitwood's work is by far the most widely referred to in dementia care. An understanding of Kitwood's ideas, in particular those of malignant social psychology and positive person work, enables nurses to develop competence in delivering optimum person-centred care to people with dementia in clinical practice.

    The contamination of linen and air in a bed centre, supply station and ward were compared, as well as the contamination of gowns used by the staff working in the 'clean' and the 'dirty' rooms of the bed-centre. The contamination of linen and air was low and there was no significant difference between the tested areas. The contamination on gowns used by the staff working in the 'dirty' room was significantly higher than that on gowns used by the staff working in the 'clean' room. This stresses the importance of dividing a bed centre into 'clean' and 'dirty' rooms. So organized, a bed centre does not seem to be a hygienic hazard. PMID:7057024

    Enantiomeric resolution of multichiral centre racemates is an important area as some multichiral centre racemates are of great medicinal importance. However, enantioseparation of such types of racemates is a challenging task. Amongst many analytical techniques, capillary electrophoresis is a powerful technique and may be used to resolve such racemates. Only few papers are available describing enantiomeric resolution of such racemates. Therefore, efforts have been made to describe the enantiomeric resolution of multichiral centre racemates by capillary electrophoresis. This article discusses the importance of multichiral racemates, the need for capillary electrophoresis in enantiomeric resolution and chiral resolution of multichiral centre racemates using various chiral selectors. Further, attempts have been made to discuss the future challenges and prospects of enantiomeric resolution of multichiral racemates. The various chiral selectors used for the purpose are chiral crown ether, cyclodextrins, polysaccharides, macrocyclic glycopeptide antibiotics and ligand exchange.

    Background In Italy, basic health needs of patients with inherited bleeding disorders are met by a network of 50 haemophilia centres belonging to the Italian Association of Haemophilia Centres. Further emerging needs, due to the increased life expectancy of this patient group, require a multi-professional clinical management of the disease and provide a challenge to the organisation of centres. In order to achieve harmonised quality standards of haemophilia care across Italian Regions, an institutional accreditation model for haemophilia centres has been developed. Material and methods To develop an accreditation scheme for haemophilia centres, a panel of experts representing medical and patient bodies, the Ministry of Health and Regional Health Authorities has been appointed by the National Blood Centre. Following a public consultation, a technical proposal in the form of recommendations for Regional Health Authorities has been formally submitted to the Ministry of Health and has formed the basis for a proposal of Agreement between the Government and the Regions. Results The institutional accreditation model for Haemophilia Centres was approved as an Agreement between the Government and the Regions in March 2013. It identified 23 organisational requirements for haemophilia centres covering different areas and activities. Discussion The Italian institutional accreditation model aims to achieve harmonised quality standards across Regions and to implement continuous improvement efforts, certified by regional inspection systems. The identified requirements are considered as necessary and appropriate in order to provide haemophilia services as basic healthcare levels under the umbrella of the National Health Service. This model provides Regions with a flexible institutional accreditation scheme that can be potentially extended to other rare diseases. PMID:24922290

  3. A relational conceptual framework for multidisciplinary health research centre infrastructure

    PubMed Central

    2010-01-01

    Although multidisciplinary and team-based approaches are increasingly acknowledged as necessary to address some of the most pressing contemporary health challenges, many researchers struggle with a lack of infrastructure to facilitate and formalise the requisite collaborations. Specialised research centres have emerged as an important organisational solution, yet centre productivity and sustainability are frequently dictated by the availability and security of infrastructure funds. Despite being widely cited as a core component of research capacity building, infrastructure as a discrete concept has been rather analytically neglected, often treated as an implicit feature of research environments with little specification or relegated to a narrow category of physical or administrative inputs. The terms research infrastructure, capacity, and culture, among others, are deployed in overlapping and inconsistent ways, further obfuscating the crucial functions of infrastructure specifically and its relationships with associated concepts. The case is made for an expanded conceptualisation of research infrastructure, one that moves beyond conventional 'hardware' notions. Drawing on a case analysis of NEXUS, a multidisciplinary health research centre based at the University of British Columbia, Canada, a conceptual framework is proposed that integrates the tangible and intangible structures that interactively underlie research centre functioning. A relational approach holds potential to allow for more comprehensive accounting of the returns on infrastructure investment. For those developing new research centres or seeking to reinvigorate existing ones, this framework may be a useful guide for both centre design and evaluation. PMID:20925953

  4. Assuring optimal trauma care: the role of trauma centre accreditation

    2002-01-01

    Optimal care of the injured patient requires the delivery of appropriate, definitive care shortly after injury. Over the last 30 to 40 years, civilian trauma systems and trauma centres have been developed in the United States based on experience gained in military conflicts, particularly in Korea and Vietnam. A similar process is evolving in Canada. National trauma committees in the US and Canada have defined optimal resources to meet the goal of rapid, appropriate care in trauma centres. They have introduced programs (verification or accreditation) to externally audit trauma centre performance based on these guidelines. It is generally accepted that implementing trauma systems results in decreased preventable death and improved survival after trauma. What is less clear is the degree to which each facet of trauma system development contributes to this improvement. The relative importance of national performance guidelines and trauma centre audit as integral steps toward improved outcomes following injury are reviewed. Current Trauma Association of Canada guidelines for trauma centres are presented and the process of trauma centre accreditation is discussed. PMID:12174987

  6. The Yale Cost Model and cost centres: servant or master?

    PubMed

    Rigby, E

    1993-01-01

    Cost accounting describes that aspect of accounting which collects, allocates and controls the cost of producing a service. Costing information is primarily reported to management to enable control of costs and to ensure the financial viability of units, departments and divisions. As costing studies continue to produce estimates of Diagnosis Related Group (DRG) costs in New South Wales hospitals, as well as in other states, costs for different hospitals are being externally compared, using a tool which is usually related to internal management and reporting. Comparability of costs is assumed even though accounting systems differ. This paper examines the cost centre structures at five major teaching hospitals in Sydney. It describes the similarities and differences in how the cost centres were constituted, and then details the line items of expenditure that are charged to each cost centre. The results of a comparative study of a medical specialty are included as evidence of different costing methodologies in the hospitals. The picture that emerged from the study is that the hospitals are constituting their cost centres to meet their internal management needs, that is, to know the cost of running a ward or nursing unit, a medical specialty, department and so on. The rationale for the particular cost centre construction was that cost centre managers could manage and control costs and assign responsibility. There are variations in procedures for assigning costs to cost centres, and the question is asked 'Do these variations in procedures make a material difference to our ability to compare costs per Diagnosis Related Group at the various hospitals?' It is contended that the accounting information, which is produced as a result of different practices, is primarily for internal management, not external comparison. It would be better for hospitals to compare their estimated costs per Diagnosis Related Group to an internal standard cost rather than the costs from other hospitals. This is because there are differences in cost centre construction and standardisation of cost centre definitions will not meet the information needs of internal management. Also capabilities and capacities of accounting systems vary greatly and uniformity will take a long time to achieve, if ever. PMID:10127677

    The main motivation of this project is to improve the healthcare centres equipment and human resources efficiency, enabling those centres for transmission of parameters of medical interest. This system facilitates remote consultation, in particular between specialists and remote healthcare centres. Likewise it contributes to the qualification of professionals. The electrocardiographic (ECG) and electroencephalographic (EEG) signals are acquired, processed and then sent, fulfilling the effective norms, for application in the hospital network of Córdoba Province, which has nodes interconnected by phone line. As innovative aspects we emphasized the low cost of development and maintenance, great versatility and handling simplicity with a modular design for interconnection with diverse data transmission media (Wi-Fi, GPRS, etc.). Successfully experiences were obtained during the acquisition of the signals and transmissions on wired LAN networks. As improvements, we can mention: energy consumption optimization and mobile communication systems usage, in order to offer more autonomy.

    2007-01-01

    Summary The need for professional management of dysphagic patients is growing. The scenario of patient care settings spans from the acute ward to chronic care facilities or home, requiring a health care network able to integrate hospital and community resources and optimise human and instrumental resources. This is also valid for Swallowing Centres, where admission, management, treatment and follow-up of discharged patients are a priority. The complexity of symptoms and the specificity of the underlying disease require a multidisciplinary approach to the patient. The coordinator of the Swallowing Centre is a phoniatrician working together with a logopedist. Patient management and personalized therapeutic options are discussed collegially. The logopedist, coordinating the activity of other therapists in the Centre, is responsible for patient treatment. In addition, the logopedist is responsible for counselling patients, nurses and informal caregivers. PMID:17957851

    Data analysis for the eLISA/NGO mission is going to be performed in several steps. The telemetry is unpacked and checked at ESA's Science Operations Centre (SOC). The instrument teams are providing the necessary calibration files for the SOC to process the Level 1 data. The next steps, the source identification, parameter extraction and construction of a catalogue of sources is performed at the Data Processing Centre (DPC). This includes determining the physical and astrophysical parameters of the sources and their strain time series. At the end of the processing, the produced Level 2 and Level 3 data are then transferred back to the SOC, which provides the data archive and the interface for the scientific community. The DPC is organised by the member states of the consortium. In this paper we describe a possible outline of the data processing centre, including the tasks to be performed, and the organisational structure.

    Increasingly women at high risk of breast cancer are opting for prophylactic surgery to reduce their risks. Data from 10 European centres that offer a risk counselling and screening service to women at risk show different approaches to the option of preventive surgery, although most centres adhere to a protocol including at least two risk counselling sessions and a psychological assessment. Thus far the combined centres have data on 174 women who have undergone prophylactic mastectomy with in excess of 400 women years of follow up. Operations were carried out on women with lifetime risks of 2580%, with an average annual expected incidence rate of 1% per women. No breast cancers have occurred in this cohort. Long term follow up on an extended group of women will be necessary to truly address the risk of subsequent breast cancer and the psychological sequelae. PMID:10595270

    This paper examines the experience of poverty and child maltreatment among New Zealand's children as compared with international statistics. New Zealand was a signatory to the United Nations Convention on the Rights of the Child in 1993, yet indicators suggest that implementation of the Articles of the Convention is limited. In the league of Organisation for Economic Co-operation and Development countries it ranks 23rd out of 26 for child poverty and 24th out of 27 for the child maltreatment death rate. A case will be made for coordination of existing and new services for children and families through a dedicated children's centre, modelled on the United Kingdom's Sure Start and Children's Centre program that was modelled in part on the Head Start program of the United States. The paper reports on Wellsford, a rural community north of Auckland, which has embraced the children's centre concept and is investigating ways to obtain funding to implement the idea. PMID:17266496

    Over the past six years, the CADC has moved beyond the astronomy archive data centre to a multi-service system for the community. This evolution is based on two major initiatives. The first is the adoption of International Virtual Observatory Alliance (IVOA) standards in both the system and data architecture of the CADC, including a common characterization data model. The second is the Canadian Advanced Network for Astronomical Research (CANFAR), a digital infrastructure combining the Canadian national research network (CANARIE), cloud processing and storage resources (Compute Canada) and a data centre (Canadian Astronomy Data Centre) into a unified ecosystem for storage and processing for the astronomy community. This talk will describe the architecture and integration of IVOA and CANFAR services into CADC operations, the operational experiences, the lessons learned and future directions

    Neuroectodermal signalling centres induce and pattern many novel vertebrate brain structures but are absent, or divergent, in invertebrate chordates. This has led to the hypothesis that signalling centre genetic programs were first assembled in stem vertebrates, which potentially drove morphological innovations. However, this scenario presumes that extant cephalochordates accurately represent ancestral chordate characters, which has not been tested using close chordate outgroups. Here, we report that genetic programs homologous to three vertebrate signalling centres; the anterior neural ridge, zona limitans intrathalamica, and isthmic organizer are present in the hemichordate Saccoglossus kowalevskii. Fgf8/17/18, sfrp1/5, hh, and wnt1 are expressed in vertebrate-like arrangements in hemichordate ectoderm, and homologous genetic mechanisms regulate ectodermal patterning in both animals. We propose these genetic programs were components of an unexpectedly complex, ancient genetic regulatory scaffold for deuterostome body patterning that degenerated in amphioxus and ascidians, but was retained to pattern divergent structures in hemichordates and vertebrates.

    The Centre for Addictions Research of British Columbia (CARBC) was established as a multi-campus and multi-disciplinary research centre administered by the University of Victoria (UVic) in late 2003. Its core funding is provided from interest payments on an endowment of CAD 10.55 million dollars. It is supported by a commitment to seven faculty appointments in various departments at UVic. The Centre has two offices, an administration and research office in Victoria and a knowledge exchange unit in Vancouver. The two offices are collaborating on the implementation of CARBC's first 5-year plan which seeks to build capacity in British Columbia for integrated multi-disciplinary research and knowledge exchange in the areas substance use, addictions and harm reduction. Present challenges include losses to the endowment caused by the 2008/2009 economic crisis and difficulties negotiating faculty positions with the university administration. Despite these hurdles, to date each year has seen increased capacity for the Centre in terms of affiliated scientists, funding and staffing as well as output in terms of published reports, electronic resources and impacts on policy and practice. Areas of special research interest include: drug testing in the work-place, epidemiological monitoring, substance use and injury, pricing and taxation policies, privatization of liquor monopolies, polysubstance use, health determinants of indigenous peoples, street-involved youth and other vulnerable populations at risk of substance use problems. Further information about the Centre and its activities can be found on http://www.carbc.ca. PMID:20078479

    Risk management for people with dementia has traditionally focused on preventing physical harm. However, research has demonstrated that focusing on the physical safety of people with dementia may result in their social and psychological wellbeing being overlooked - the very aspects that are necessary to achieve person-centred care. This article discusses the main challenges for practitioners caring for people with dementia in various settings, and encourages a care approach which enables appropriate risk taking as a way of promoting person-centred care.

    Mangiarotti, Michela

    Energy efficiency in shopping centres means providing comfortable internal environment and services to the occupants with minimum energy use in a cost-effective and environmentally sensitive manner. This research considers the interaction of three factors affecting the energy efficiency of shopping centres: i) performance of the building fabric and services ii) management of the building in terms of operation, control, maintenance and replacement of the building fabric and services, and company's energy policy iii) occupants' expectation for comfort and awareness of energy efficiency. The aim of the investigation is to determine the role of the above factors in the energy consumption and carbon emissions of shopping centres and the scope for reducing this energy usage by changing one or all the three factors. The study also attempts to prioritize the changes in the above factors that are more cost-effective at reducing that energy consumption and identify the benefits and main economic and legal drivers for energy efficiency in shopping centres. To achieve these targets, three case studies have been analysed. Using energy data from bills, the performance of the selected case studies has been assessed to establish trends and current energy consumption and carbon emissions of shopping centres and their related causes. A regression analysis has attempted to break down the energy consumption of the landlords' area by end-use to identify the main sources of energy usage and consequently introduce cost-effective measures for saving energy. A monitoring and occupants' survey in both landlords' and tenants' areas have been carried out at the same time to compare the objective data of the environmental conditions with the subjective impressions of shoppers and shopkeepers. In particular, the monitoring aimed at assessing the internal environment to identify possible causes of discomfort and opportunities for introducing energy saving measures. The survey looked at determining the occupants' expectation for comfort and awareness of energy efficiency in shopping centres. The results show the complexity of prioritizing the three factors affecting energy efficiency in shopping centres, highlighting the relationships between those factors, and the role of different actors, involved in the life of shopping centres, in the energy and environmental performance of these buildings.

  20. The academic medical centre: an idea whose time has come.

    Interdependence of faculties of medicine or health sciences and teaching hospitals is central to the academic medical centre's three "products": education, research and clinical service. Whether a voluntary association, partnership, joint venture or single entity, the strength of the association of member institutions must lie in mutual dependency. With the potential of reducing costs and increasing effectiveness through administrative efficiency and rationalization, especially of planning and setting priorities, the academic medical centre can outstrip its individual member institutions in contributing to the solution of Canada's present and future challenges in health care.

  1. Stakeholder perceptions of a nurse led walk-in centre

    PubMed Central

    2012-01-01

    Background As many countries face primary care medical workforce shortages and find it difficult to provide timely and affordable care they seek to find new ways of delivering first point of contact health care through developing new service models. In common with other areas of rural and regional Australia, the Australian Capital Territory (ACT) is currently experiencing a general practitioner (GP) workforce shortage which impacts significantly on the ability of patients to access GP led primary care services. The introduction of a nurse led primary care Walk-in Centre in the ACT aimed to fulfill an unmet health care need in the community and meet projected demand for health care services as well as relieve pressure on the hospital system. Stakeholders have the potential to influence health service planning and policy, to advise on the potential of services to meet population health needs and to assess how acceptable health service innovation is to key stakeholder groups. This study aimed to ascertain the views of key stakeholders about the Walk-in Centre. Methods Stakeholders were purposively selected through the identification of individuals and organisations which had organisational or professional contact with the Walk-in Centre. Semi structured interviews around key themes were conducted with seventeen stakeholders. Results Stakeholders were generally supportive of the Walk-in Centre but identified key areas which they considered needed to be addressed. These included the service's systems, full utilisation of the nurse practitioner role and adequate education and training. It was also suggested that a doctor could be available to the Centre as a source of referral for patients who fall outside the nurses' scope of practice. The location of the Centre was seen to impact on patient flows to the Emergency Department. Conclusion Nurse led Walk-in Centres are one response to addressing primary health care medical workforce shortages. Whilst some stakeholders have reservations about the model others are supportive and see the potential the model has to provide accessible primary health care. Any further developments of nurse-led Walk-in Centres need to take into account the views of key stakeholders so as to ensure that the model is acceptable and sustainable. PMID:23126431

  2. The role of sedimentology, oceanography, and alteration on the δ56Fe value of the Sokoman Iron Formation, Labrador Trough, Canada

    The Sokoman Formation is a ca. 100-m-thick succession of interbedded iron formation and fine-grained siliciclastics deposited at 1.88 Ga. Accumulation occurred on a dynamic paleoshelf where oxygen stratification, coastal upwelling of hydrothermally derived Fe and Si, microbial processes, tide and storm currents, diagenesis, and low-grade prehnite-pumpellyite metamorphism controlled lithofacies character and produced complex associations of multigenerational chert, hematite, magnetite, greenalite, stilpnomelane and Fe carbonate. Hematite-rich facies were deposited along suboxic segments of the coastline where photosynthetic oxygen oases impinged on the seafloor. Hematitic, cross-stratified grainstones were formed by winnowing and reworking of freshly precipitated Fe-(oxyhydr)oxide and opal-A by waves and currents into subaqueous dunes. Magnetite-rich facies contain varying proportions of greenalite and stilpnomelane and record deposition in anoxic middle shelf environments beneath an oxygen chemocline. Minor negative Ce anomalies in hematitic facies, but prominent positive Ce and Eu anomalies and high LREE/HREE ratios in magnetite-rich facies imply the existence of a weakly oxygenated surface ocean above anoxic bottom waters. The Fe isotopic composition of 31 whole rock (-0.46 ⩽ δ56Fe ⩽ 0.47‰) and 21 magnetite samples (-0.29 ⩽ δ56Fe ⩽ 0.22‰) from suboxic and anoxic lithofacies was controlled primarily by the physical oceanography of the paleoshelf. Despite low-grade metamorphism recorded by the δ18O values of paragenetically related quartz and magnetite, the Sokoman Formation preserves a robust primary Fe isotopic signal. Coastal upwelling is interpreted to have affected the isotopic equilibria between Fe2+aq and Fe-(oxyhydr)oxide in open marine versus coastal environments, which controlled the Fe isotopic composition of lithofacies. Unlike previous work that focuses on microbial and abiotic fractionation processes with little regard for paleoenvironment, our work demonstrates that depositional setting is paramount in governing the Fe isotopic composition of iron formations irrespective of what Fe-bearing minerals precipitated.

  19. Squaraine dyes as efficient coupling bridges between triarylamine redox centres.

    PubMed

    Völker, Sebastian F; Renz, Manuel; Kaupp, Martin; Lambert, Christoph

    2011-12-01

    Various indolenine squarylium dyes with additional electron-donating amine redox centres have been synthesised and their redox chemistry has been studied. A combination of cyclic voltammetry, spectro-electrochemistry and DFT calculations has been used to characterise the electronic structure of the mono-, di- and, in one case, trications. All monocations still retain the cyanine-like, delocalised character due to the relatively low redox potential of the squaraine bridge and are therefore compounds of Robin-Day class III. Thus we extended previous studies on organic mixed-valence systems by using the indolenine squaraine moiety as very electron-rich bridge between two electron-donating amine redox centres to provoke a strong coupling between the additional redox centres. We synthesised TA3, which has an N-N distance of 26 bonds between the triarylamine redox centres and is to our knowledge the longest bis(triarylamine) radical cation that is completely delocalised. We furthermore show that altering the symmetry of a squaraine dye by substitution of a squaric ring oxygen atom by a dicyanomethylene group has a direct impact on the optical properties of the monocations. In case of the dications, it turned out that the energetically most stable state of dianisylamine-substituted squaraines is an anti-ferromagnetically coupled open-shell singlet state. PMID:22083939

    2016-02-01

    The number of adolescents and young adults with chronic diseases has increased dramatically over the last decade. This led paediatric teams to organize the transition to adult centres with the aim to ensure the quality of care and prognosis, adherence to survey and treatment. To promote a good work and family life is also a challenge. Several studies have shown the importance of a successful transition in cystic fibrosis (CF) in order to prevent complications and loss monitoring and to improve the perception of patients and their families. In France in 2003, cystic fibrosis centres (CRCM) have been identified and among them of adult CF centres. The regular increase of the adult centre's active file requires improving the transition process. It is necessary to improve the transition process and to prepare the young patient and their family early during adolescence. The process in place should concern the whole aspects of care, i.e., medical, psychological and educational. The transition to adulthood will be successful if it results in a stable state of the disease allowing family and career plans. PMID:26190340

    2016-04-01

    In a developing country such as India, there is substantial inequality in health care distribution. Telemedicine facilities were established in Madhya Pradesh in 2007-2008. The purpose of this study was to evaluate the infrastructure, equipment, manpower, and functional status of Indian Space and Research Organisation (ISRO) telemedicine nodes in Madhya Pradesh. All district hospitals and medical colleges with nodes were visited by a team of three members. The study was conducted from December 2013-January 2014. The team recorded the structural facility situation and physical conditions on a predesigned pro forma. The team also conducted interviews with the nodal officers, data entry operator and other relevant people at these centres. Of the six specialist nodes, four were functional and two were non-functional. Of 10 patient nodes, two nodes were functional, four were semi-functional and four were non-functional. Most of the centres were not working due to a problem with their satellite modem. The overall condition of ISRO run telemedicine centres in Madhya Pradesh was found to be poor. Most of these centres failed to provide telemedicine consultations. We recommend replacing this system with another cost effective system available in the state wide area network (SWAN). We suggest the concept of the virtual out-patient department. PMID:26156940

    The aim of this study was to assess the characteristics of patients with coronoid fractures treated in two European centres over 10 years and to briefly review the literature. This study is based on 2 systematic computer-assisted databases that have continuously recorded patients hospitalized with maxillofacial fractures and surgically treated in two European centres between 2001 and 2010. During the 10 years, 1818 patients and 523 patients with maxillofacial fractures were admitted to the two centres respectively: 21 patients (16 males, 5 females) were admitted with 21 coronoid fractures and 28 associated maxillofacial fractures. A mean age of 42.1 years was observed. The fractures were mainly the result of motor vehicle accidents, followed by assaults and falls. The most frequently observed associated maxillofacial fracture was a zygomatic fracture (13 fractures). In both centres, mandibular coronoid fractures are treated unless a severe dislocation of the fractured coronoid is observed or a functional mandibular impairment is encountered. Conservative treatment can be used, together with the open reduction and internal fixation of associated fractures. The crucial point is to prevent ankylosis, which may be prevented by correct and early postoperative physiotherapy and mandibular function. PMID:24787084

    2016-01-01

    We aimed to identify regional centres of plant biodiversity in South Australia, a sub-continental land area of 983,482 km2, by mapping a suite of metrics. Broad-brush conservation issues associated with the centres were mapped, specifically climate sensitivity, exposure to habitat fragmentation, introduced species and altered fire regimes. We compiled 727,417 plant species records from plot-based field surveys and herbarium records and mapped the following: species richness (all species; South Australian endemics; conservation-dependent species; introduced species); georeferenced weighted endemism, phylogenetic diversity, georeferenced phylogenetic endemism; and measures of beta diversity at local and state-wide scales. Associated conservation issues mapped were: climate sensitivity measured via ordination and non-linear modelling; habitat fragmentation represented by the proportion of remnant vegetation within a moving window; fire prone landscapes assessed using fire history records; invasive species assessed through diversity metrics, species distribution and literature. Compared to plots, herbarium data had higher spatial and taxonomic coverage but records were more biased towards major transport corridors. Beta diversity was influenced by sampling intensity and scale of comparison. We identified six centres of high plant biodiversity for South Australia: Western Kangaroo Island; Southern Mount Lofty Ranges; Anangu Pitjantjatjara Yankunytjatjara lands; Southern Flinders Ranges; Southern Eyre Peninsula; Lower South East. Species composition in the arid-mediterranean ecotone was the most climate sensitive. Fragmentation mapping highlighted the dichotomy between extensive land-use and high remnancy in the north and intensive land-use and low remnancy in the south. Invasive species were most species rich in agricultural areas close to population centres. Fire mapping revealed large variation in frequency across the state. Biodiversity scores were not always congruent between metrics or datasets, notably for categorical endemism to South Australia versus georeferenced weighted endemism, justifying diverse approaches and cautious interpretation. The study could be extended to high resolution assessments of biodiversity centres and cost:benefit analysis for interventions. PMID:26735131

    Objectives The UK government's response to the obesity epidemic calls for action in communities to improve people's health behaviour. This study evaluated the effects of a community intervention on dietary quality and levels of physical activity of women from disadvantaged backgrounds. Design Non-randomised controlled evaluation of a complex public health intervention. Participants 527 women attending Sure Start Children's Centres (SSCC) in Southampton (intervention) and 495 women attending SSCCs in Gosport and Havant (control). Intervention Training SSCC staff in behaviour change skills that would empower women to change their health behaviours. Outcomes Main outcomes dietary quality and physical activity. Intermediate outcomes self-efficacy and sense of control. Results 1-year post-training, intervention staff used skills to support behaviour change significantly more than control staff. There were statistically significant reductions of 0.1 SD in the dietary quality of all women between baseline and follow-up and reductions in self-efficacy and sense of control. The decline in self-efficacy and control was significantly smaller in women in the intervention group than in women in the control group (adjusted differences in self-efficacy and control, respectively, 0.26 (95% CI 0.001 to 0.50) and 0.35 (0.05 to 0.65)). A lower decline in control was associated with higher levels of exposure in women in the intervention group. There was a statistically significant improvement in physical activity in the intervention group, with 22.9% of women reporting the highest level of physical activity compared with 12.4% at baseline, and a smaller improvement in the control group. The difference in change in physical activity level between the groups was not statistically significant (adjusted difference 1.02 (0.74 to 1.41)). Conclusions While the intervention did not improve women's diets and physical activity levels, it had a protective effect on intermediate factors—control and self-efficacy—suggesting that a more prolonged exposure to the intervention might improve health behaviour. Further evaluation in a more controlled setting is justified. PMID:25031194

    The Centre for Addictions Research of British Columbia (CARBC) was established as a multi-campus and multi-disciplinary research centre administered by the University of Victoria (UVic) in late 2003. Its core funding is provided from interest payments on an endowment of CAD$10.55 million. It is supported by a commitment to seven faculty appointments in various departments at UVic. The Centre has two offices, an administration and research office in Victoria and a knowledge exchange unit in Vancouver. The two offices are collaborating on the implementation of CARBCs first 5-year plan which seeks to build capacity in British Columbia for integrated multi-disciplinary research and knowledge exchange in the areas substance use, addictions and harm reduction. Present challenges include losses to the endowment caused by the 2008/2009 economic crisis and difficulties negotiating faculty positions with the university administration. Despite these hurdles, to date each year has seen increased capacity for the Centre in terms of affiliated scientists, funding and staffing as well as output in terms of published reports, electronic resources and impacts on policy and practice. Areas of special research interest include: drug testing in the work-place, epidemiological monitoring, substance use and injury, pricing and taxation policies, privatization of liquor monopolies, poly-substance use, health determinants of indigenous peoples, street-involved youth and other vulnerable populations at risk of substance use problems. Further information about the Centre and its activities can be found on http://www.carbc.ca. PMID:20078479

  13. Commercial applications of satellite oceanography

    1981-01-01

    It is shown that in the next decade the oceans' commercial users will require an operational oceanographic satellite system or systems capable of maximizing real-time coverage over all ocean areas. Seasat studies suggest that three spacecraft are required to achieve this. Here, the sensor suite would measure surface winds, wave heights (and spectral energy distribution), ice characteristics, sea-surface temperature, ocean colorimetry, height of the geoid, salinity, and subsurface thermal structure. The importance of oceanographic data being distributed to commercial users within two hours of observation time is stressed. Also emphasized is the importance of creating a responsive oceanographic satellite data archive. An estimate of the potential dollar benefits of such an operational oceanographic satellite system is given.

    The NASA Ocean Topography Experiment (TOPEX) will use precision radar altimetry to determine topographic features of the global oceans from which currents may be deduced. TOPEX will coincide with the World Ocean Circulation Experiment (WOCE), which will be conducted at the end of this decade and shall involve ships, fixed and drifting buoys, aircraft observations, and satellite remote sensing, to resolve fundamental questions about the flow of water in the global ocean. TOPEX will contribute to WOCE the measurement of satellite height above the sea surface, and the precise radial position above a reference ellipsoid for the earth. The combination of these two measurements with the marine geoid yields the topographic data sought. Three years of topographic data, together with conventional oceanographic data and theoretical ocean models, will be needed to derive the mean and variable components of ocean circulation.

    The main attribute of remote sensing is seen as its ability to measure distributions over large areas on a synoptic basis and to repeat this coverage at required time periods. The way in which the Coastal Zone Color Scanner, by showing the distribution of chlorophyll a, can locate areas productive in both phytoplankton and fishes is described. Lidar techniques are discussed, and it is pointed out that lidar will increase the depth range for observations.

    The rate of marine photosynthesis is of great importance for the global carbon cycle but is difficult to measure from environmental properties or in vitro. In this Perspective, Bender highlights a study by Luz and Barkan, who exploit the anomalous isotopic composition of molecular oxygen to determine the gross rate of photosynthesis in seawater. The method allows much longer time scales and larger spatial scales to be covered than with traditional oceanographic techniques. PMID:17835109

  17. Physical oceanography of oil spills

    SciTech Connect

    Murray, S.P. )

    1991-03-01

    The introduction of petroleum products and crude oil from ship accidents and damaged platforms into the ocean remains a significant problem. Weather systems of nearly all sizes and time scales may have strong effects on oil slick movement and dispersal. Thunderstorms, local weather systems, mid-latitude high- and low-pressure systems, tropical cyclones, and the trade winds and prevailing westerlies of the planetary wind system are all potentially important agents in the movement and dispersal of oil slicks. Currents driven by these wind systems are influenced by the rotation of the earth, which causes them to veer to the right of the wind in the northern hemisphere. Wind shifts or sudden decreases in wind stress induce circular or inertial oscillations whose period varies with latitude. Near the shore these effects are severely damped by the blocking action of the coast, causing the flow to run more or less parallel to the coastal boundary. All these effects will in turn exert significant control over the movement of entrained oil slicks. In the near-field region of an oil spill tidal currents can also be of considerable importance. Rotary currents, characteristic of open-shelf waters and effective dispersal agents of oil, arise from the influence of the rotation of the earth on the tidal current. Another such interaction between rotation of the earth and the tide produces Kelvin waves, which result in unusually high tidal ranges along the coast to the right of the tidal wave propagation. Both effects have been important in recent oil spills. All these oceanographic processes, reviewed in this talk, have played key roles in major spills over the last 15 years from the Torrey Canyon to the Mega-Borg.

  2. Titan Oceanography from the Cassini

    NASA Astrophysics Data System (ADS)

    Lorenz, Ralph

    While the Cassini-Huygens mission was formulated against the speculative backdrop of a hydrocarbon ocean on Titan, the reality exposed by its measurements a quarter century later has proven more interesting. Instead of a global ocean, Titan has three modest seas, with dozens of small lakes, clustered around its north pole. The south is almost entirely bereft of surface liquids, the probable result of astronomically-forced climate cycles on Titan which are pumping ethane and methane vapor northwards across the equatorial deserts to accumulate in the long rainy season each boreal summer in the present epoch. Cassini’s RADAR instrument mapped the second-largest (~350km) sea, Ligiea Mare, while it was still in winter darkness, and has now covered the sprawling (~1000km) Kraken Mare, revealing shorelines indicating rising sea levels. The mapping allows the construction of numerical models of ocean circulation driven by winds and tides. Radar observations have placed tight limits (mm) on wave heights so far: near-infrared sunglint observations provide separate constraints on surface roughness. We will review latest observations and future plans: it is expected that winds will freshen as we move towards the culmination of the Cassini Solstice Mission in northern midsummer. The Ku-band (2.2cm) radar signals from Cassini penetrate a few meters into the possibly muddy dregs of Ontario Lacus in the south, yet remarkably allowed detection of a bottom echo at Ligeia Mare in a nadir-pointed altimetry observation in summer 2013. This not only allowed a depth estimation of ~170m, but also points to a very ‘clean’ composition, quite possibly rich in methane. This contrasts with near-infrared measurements at Ontario Lacus in the south, which show ethane and possibly an optically-muddy appearance. The stage is now set for detailed modeling of wind-driven and tidal circulations, mixing, stratification, sedimentation and shoreline processes on Titan. Beyond their insights into this environment, Cassini’s observations set the stage for future missions, which might include vehicles that float on, fly over, or even swim in, Titan’s exotic seas.

    The hypothesis that physical lagoon characteristics and variability depend on the channel connecting the lagoon to the adjacent coastal ocean is evaluated. The geographical, hydrological, and oceanographic characteristics of 10 lagoon systems are described and analyzed; these oceanographic features are utilized to classify the lagoon systems. Choked lagoons (Laguna Joyuda, Coorong, Lake St.Lucia, Gippsland Lakes, Lake Songkla/Thale Luang/Thale Noi, and Lagoa dos Patos) are prevalent on coasts with high wave energy and low tidal range; restricted lagoons (Lake Pontchartrain and Laguna de Terminos) are located on low/medium wave energy coasts with a low tidal range; and leaky lagoons (Mississippi Sound and Belize Lagoon/Chetumal Bay) are connected to the ocean by wide tidal passes that transmit oceanic effects into the lagoon with a minimum of resistance. The data support the hypothesis that the nature of the connecting channel controls system functions.

    2014-01-01

    Background The burden of cardiovascular disease world-wide is one of great concern to patients and health care agencies alike. Traditionally centre-based cardiac rehabilitation (CR) programmes are offered to individuals after cardiac events to aid recovery and prevent further cardiac illness. Home-based cardiac rehabilitation programmes have been introduced in an attempt to widen access and participation. Objectives To determine the effectiveness of home-based cardiac rehabilitation programmes compared with supervised centre-based cardiac rehabilitation on mortality and morbidity, health-related quality of life and modifiable cardiac risk factors in patients with coronary heart disease. Search methods We updated the search of a previous review by searching the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (2007, Issue 4), MEDLINE, EMBASE and CINAHL from 2001 to January 2008. We checked reference lists and sought advice from experts. No language restrictions were applied. Selection criteria Randomised controlled trials (RCTs) that compared centre-based cardiac rehabilitation (e.g. hospital, gymnasium, sports centre) with home-based programmes, in adults with myocardial infarction, angina, heart failure or who had undergone revascularisation. Data collection and analysis Studies were selected independently by two reviewers, and data extracted by a single reviewer and checked by a second one. Authors were contacted where possible to obtain missing information. Main results Twelve studies (1,938 participants) met the inclusion criteria. The majority of studies recruited a lower risk patient following an acute myocardial infarction (MI) and revascularisation. There was no difference in outcomes of home- versus centre-based cardiac rehabilitation in mortality risk ratio (RR) was 1.31 (95% confidence interval (C) 0.65 to 2.66), cardiac events, exercise capacity standardised mean difference (SMD) −0.11 (95% CI −0.35 to 0.13), as well as in modifiable risk factors (systolic blood pressure; diastolic blood pressure; total cholesterol; HDL-cholesterol; LDL-cholesterol) or proportion of smokers at follow up or health-related quality of life. There was no consistent difference in the healthcare costs of the two forms of cardiac rehabilitation. Authors’ conclusions Home- and centre-based cardiac rehabilitation appear to be equally effective in improving the clinical and health-related quality of life outcomes in acute MI and revascularisation patients. This finding, together with an absence of evidence of difference in healthcare costs between the two approaches, would support the extension of home-based cardiac rehabilitation programmes such as the Heart Manual to give patients a choice in line with their preferences, which may have an impact on uptake of cardiac rehabilitation in the individual case.

    Practice simulation in acute and pre-hospital care settings is a growing area of interest for clinicians and health educationalists, and there is much evidence to support its use ( Pike and O'Donnell 2010 ). Most simulation is delivered through computer-aided software or in virtual environments, however last year the University of Hertfordshire opened an accident simulation centre which is an outdoor facility that offers pre- and post-registration paramedics the opportunity to experience a range of scenarios in a 'real life' but secure environment. This article describes how the centre enables students to apply theory to practice in complex situations, such as managing patients injured in road traffic collisions. PMID:26853672

    2013-01-01

    Patient-centred system of care is essential in managing many disorders such as diabetes mellitus. The cultural and religious context can influence the involvement of patients and their families in such a care. We intend to discuss patient-centred care in diabetology in view of Islam. For more clarification, we will take into consideration a few illustrative lines of argument in detail about situation in Iran. In conclusion, dynamic spirit of Islamic jurisprudence is reflected in its adaptability to change in medical practice. In recent decades, Iranian religious scholars have provided scientists in new fields of science and research with appropriate directions and guidelines. Decree issued by Iranian religious leaders permitting research on stem cells for therapeutic purposes in many disorders including diabetes mellitus is one example. Understanding of the nature of Islam is importance for communication with patients in Islamic countries. PMID:23663445

    We use recently updated globular cluster distances to estimate the distance to the Galactic Centre, finding 7.4 ± 0.2|stat ± 0.2|sys kpc from symmetry considerations, including a trough at the Galactic Centre and peaks denoting the position of the bar. We recalibrate the red clump magnitude from Hipparcos stars, finding a skew distribution and a significant difference between peak and mean magnitudes. We find an estimate from stars in the periphery of the bulge using 2MASS, R0 = 7.5 ± 0.3 kpc, in agreement with the figure from the halo centroid. We resolve discrepancies in the literature between estimates from the red clump. Our results are consistent with those found by different methodologies after taking systematic errors into account.

    Reißer, Sabin

    The German grid initiative D-Grid brings together various scientific and commercial projects in fields like medicine, engineering, banking, meteorology using the same grid infrastructure. In this infrastructure, which comprises more than 30 computing centres, three middleware stacks (gLite, Globus and Unicore) are deployed and used by the various communities. This variety of applications as well as of middleware calls for well organised operations and support. The German Grid Operations and Support Centre (GOSC) aim to answer this challenge and also provides an uplink to international activities like EGI. The GOSC will provide middleware services like reference installations for the various middleware flavours. It will manage the national grid operations (regional monitoring, SLA enforcement) and will be responsible for providing VO and user services, like application support and a helpdesk.

    The European Space Agency’s(ESA) experts in quality, cleanliness and contamination control, safety, test facilities and test methods have accumulated valuable experience during the performance of dedicated audits of space test centres in Europe over a period of 10 years. This paper is limited to a summary of the safety findings and provides a valuable reference to the lessons learned, identifying opportunities for improvement in the areas of risk prevention measures associated to the safety of all test centre personnel, the test specimen, the test facilities and associated infrastructure. Through the analysis of the audit results the authors present what are the main lessons learned, and conclude how an effective safety management system will contribute to successful test campaigns and have a positive impact on the cost and schedule of space projects.

    Obesity is recognised as a global epidemic and the most prevalent metabolic disease world-wide. Specialised obesity services, however, are not widely available in Europe, and obesity care can vary enormously across European regions. The European Association for the Study of Obesity (EASO, www.easo.org) has developed these criteria to form a pan-European network of accredited EASO-Collaborating Centres for Obesity Management (EASO-COMs) in accordance with accepted European and academic guidelines. This network will include university, public and private clinics and will ensure that the obese and overweight patient is managed by a holistic team of specialists and receives comprehensive state-ofthe-art clinical care. Furthermore, the participating centres, under the umbrella of EASO, will work closely for quality control, data collection, and analysis as well as for education and research for the advancement of obesity care and obesity science.

    Academic health centres (AHCs) bring significant economic and health benefits to a community. This study focuses on four integrated AHCs in the USA. They are described as the 'traditional great' or 'transformational great', where a number of common characteristics have been identified on how these organisations have demonstrated superior performance over time. The conceptual framework of 'good to great' provides a structure to explore key factors that support enhanced performance. PMID:20408299

  17. Demonstrable professionalism: linking patient-centred care and revalidation.

    PubMed

    Phelps, G; Dalton, S

    2013-11-01

    The move by the Medical Board of Australia to commence a conversation with the medical profession about revalidation reflects that patient-centred care is at the heart of good medical practice. Patients judge their doctors' commitment to them based on whether their individual interactions with doctors meet their needs. We argue that ensuring that doctors are continuing to perform at a level that the community regards as acceptable is a demonstration of an individual doctor's professionalism and thus their commitment to patient-centred care. This impacts on the profession as a whole, which needs to commit to what we call 'demonstrable professionalism'--the ongoing and active demonstration of performance that the community regards as acceptable. This needs to be supported by organisations in which doctors work, reflecting the importance of organisational context to clinical practice. Revalidation processes thus need both to reflect the work of doctors and be meaningful to the community. The move to consider revalidation of doctors by regulatory authorities should not be seen by the profession as a threat, but more as an opportunity to demonstrate the profession's commitment to patient-centred care.

  18. Structuring of service centres for economic and equipment efficiency.

    PubMed

    Irnich, W

    1989-01-01

    Increasing costs in healthcare have stimulated discussions on whether installation of competent in-house service groups for equipment management could eventually aid in reducing expenditure. In the Federal Republic of Germany, a four-year programme was initiated in 1979 with the purpose of investigating the feasibility, efficiency and profitability of a clinical engineering service within hospitals. The results of this programme formed the foundation on which we developed guidelines for structuring such service centres, to enable other hospitals to profit from the experience gained and possibly to avoid repeating mistakes. Service groups must have sufficient personnel to be successful. As a rough estimate, approximately one service staff member per 100 beds is needed. A more sophisticated structuring demands analysis of the repair accounts to elucidate additional parameters. An optimised service centre can reduce the maintenance costs to about 60 per cent of their original value without in-house service. Structuring of service centres for cost-effectiveness requires a simultaneous increase in service quality, which should be the highest motivation in clinical engineering. PMID:2506400

    Source contribution to atmospheric particulate matter (PM) has been exhaustively modelled. However, people spend most of their time indoors where this approach is less explored. This evidence worsens considering elders living in Elderly Care Centres, since they are more susceptible. The present study aims to investigate the PM composition and sources influencing elderly exposure. Two 2-week sampling campaigns were conducted-one during early fall (warm phase) and another throughout the winter (cold phase). PM10 were collected with two TCR-Tecora(®) samplers that were located in an Elderly Care Centre living room and in the correspondent outdoor. Chemical analysis of the particles was performed by neutron activation analysis for element characterization, by ion chromatography for the determination of water soluble ions and by a thermal optical technique for the measurement of organic and elemental carbon. Statistical analysis showed that there were no statistical differences between seasons and environments. The sum of the indoor PM10 components measured in this work explained 57 and 53 % of the total PM10 mass measured by gravimetry in warm and cold campaigns, respectively. Outdoor PM10 concentrations were significantly higher during the day than night (p value < 0.05), as well as Ca(2+), Fe, Sb and Zn. The contribution of indoor and outdoor sources was assessed by principal component analysis and showed the importance of the highways and the airport located less than 500 m from the Elderly Care Centre for both indoor and outdoor air quality.

    The bipolar-hypershell (BHS) model for the North Polar Spurs (NPS-E, -W, and Loop I) and counter southern spurs (SPS-E and -W) is revisited based on numerical hydrodynamical simulations. Propagations of shock waves produced by energetic explosive events in the Galactic Centre are examined. Distributions of soft X-ray brightness on the sky at 0.25, 0.7, and 1.5 keV in the ±50° × ±50° region around the Galactic Centre are modelled by thermal emission from high-temperature plasma in the shock-compressed shell considering shadowing by the interstellar H I and H2 gases. The result is compared with the ROSAT wide field X-ray images in R2, 4, and 6 bands. The NPS and southern spurs are well reproduced by the simulation as shadowed dumbbell-shaped shock waves. We discuss the origin and energetics of the event in relation to the starburst and/or active galactic nucleus activities in the Galactic Centre.

  1. The Centre for Trophoblast Research: improving health through placental research.

    PubMed

    Burton, Graham J

    2012-07-01

    The placenta is an essential but widely neglected organ. As the interface between the mother and her fetus, the placenta represents the platform for a healthy life. The majority of the major complications of pregnancy, including miscarriage, pre-eclampsia, intrauterine growth restriction and stillbirth, have their pathophysiological roots in poor placentation. In addition, there is now irrefutable evidence that low birthweight predisposes to a higher risk of cardiovascular and other disorders in later life. The Centre for Trophoblast Research was established in the University of Cambridge with the aim of generating new impetus and a fresh approach to address these problems. Placentation involves many different cell biological processes, some of which are unique to the trophoblast, as well as complex interactions with the maternal immune system. The Centre brings together academic clinicians and basic scientists working in diverse disciplines and provides a rich intellectual environment that facilitates novel collaborative links. The Centre also encourages new investigators into the field and fosters their careers through a number of initiatives, including support for studentships and fellowships, developing research resources, hosting an annual scientific meeting and running a training course in placental biology.

    Acrobatic gymnasts need excellent balance control to execute pyramids where one gymnast is supported by another. The objectives of this study were: (1) to describe balance performance by assessing the centre of pressure displacement in a group of acrobatic gymnasts executing pyramids; (2) to determine the relationship between the parameters describing the centre of pressure oscillations and pyramid score; and (3) to examine the role of each foot in providing a solid base of support to maintain the balance of the pyramid. Sixteen acrobatic gymnasts grouped in pairs performed a Half pyramid and a Straddle pyramid held for 7 s on two force platforms. Path length, variance, range trajectory, and surface area of the centre of pressure of each foot were examined to analyse the balance of the pyramid. The path length was correlated with the pyramid score (Straddle: p = 0.692 [large]; Half: p = 0.407 [moderate]). There were differences in the functions of each leg to maintain balance, with the non-preferred leg supporting a higher weight of the pyramid while the preferred leg performed control movements to maintain balance. The results suggested that quantitative analysis of balance can provide important information on pyramid performance. PMID:26715236

    The Met Office and the Environment Agency in the UK have set up a joint Flood Forecasting Centre (FFC), based at the London offices of the Met Office. This partnership will improve the UK's ability to respond to flooding events by providing an earlier national forecasting and alert service to central and local government departments so as to give them more time to prepare for floods and reduce the risk of loss of life and damage to property. The creation of the centre is in response to a key recommendation of Sir Michael Pitt's Review following the summer 2007 floods over the UK. For the first time, the FFC combines the Environment Agency's expertise in flood risk management and the Met Office's expertise in weather forecasting under one roof. My presentation will describe the benefits it will bring to the emergency responder community. It will also cover the tools available to the centre such as the new generation of high resolution weather models now coming on line. As a result, flood forecasting and warning systems, (which historically have been based on the lack of sufficiently fine scale rainfall information), need to be revisited in the light of the new meteorological modelling capabilities. This is particularly true for surface water flooding, where these new capabilities offer, for the first time, the possibility of providing credible alerts.

    In the Apollo programme, the role of ground operations was at the minimum due to limited communication means. The absence of support to the astronaut limited the science return of the missions by imposing very coarse operations. The Space Shuttle era saw the implementation of the Tracking and Data Relay Satellite Systems which since 1983 leads to unprecedented ground monitoring and commanding capabilities and presently allows ground operation centres to conduct experiments on the ISS either independently or in support of the crew. These aspects of telescience on the ISS are currently exercised in Europe by the USOC's (User support and Operation Centres) and a few examples of the successes of this concept on external payloads will be described. The extension of this telescience aspect to robotic exploration brings some of the advantages of manned flight to automatic missions. The advantages of testing dedicated exploration operation centres during automatic missions are of different orders: direct science enhancement, increase of the exploration manned base, direct involvement of scientists in exploration operations and finally training for the operations of the manned flights. Examples in the current and near future Mars missions will be shown. In the final stage of exploration: manned flight, the role of ground support will increase crew efficiency and limit the dangers of astronaut exhaustion. The necessary infrastructure to fulfil this role will be described.

    The present article is about the development of the science museum net in India started in 1956, when the government of that country created the Industry and Technology Museum in Calcutta. In the 1960's and 1970's, due to the need of simple programs for rural communities and small villages, the idea of Mobile Science Exhibits (MSE) started. In order to take universal scientific concepts to those who could not visit museums, the Museobus was projected. At that time, the educational focus in museums changes from exhibiting artifacts to encouraging learning through "doing". The Exploratorium in San Francisco influenced the approach of museums in India. While the first Science Centre was built in Mumbai, the Planning COmmission of the Indian government created a task force to study the development of Sciences Museums. In 1978, the National Council of Science Museums (NCSM) was created as an independent institution, which later became part of the Ministry of Education and Social Welfare. Twenty-five years after the creation of the Council, the movement for informal science teaching had acquired a solid background. In 1978, their priority was to expand the net of science Centres and Museums. Now, the priority is to achieve better quality and more efficient communication. Nowadays, Indian Science Centres evaluate the impact their activities have on individual, social and economic reality. With new technologies and approaches, they try to emphasize their relevance in a society that is characterized by having a great number of languages and poor education in science. PMID:16676474

  6. V centres in plastically deformed SrS

    V centres of several types were studied by electron paramagnetic resonance in SrS polycrystals for the first time. Both isolated cation vacancies and their complexes with other defects are formed in SrS during plastic deformation and are further transformed by ionic processes on annealing. They become paramagnetic when the samples are irradiated by X-rays at 77 K and a hole is captured by a S2- ion situated next to a cation vacancy. Thus, V- centres arise from isolated cation vacancies vc, VSH from vc - (SH)- complexes, and V2(SH)+ from (SH)- - vc - (SH)- complexes. The holes captured are released from V centres below room temperature, within a very wide temperature range. The electric fields of dislocations are supposed to modify the activation energies of hole release. Low activation temperatures of ionic processes (compared with ionic conductivity of undamaged SrS) indicate that defects are transported by dislocations in plastically deformed SrS.

  7. Climatology of the oceanography in the northern South China Sea Shelf-sea (NoSoCS) and adjacent waters: Observations from satellite remote sensing

    By using the observations from multiple satellite sensors, the climatology of the oceanography, including the surface wind vector, sea surface temperature (SST), surface chlorophyll a concentration (Chl_a), and vertically integrated net primary production (PPeu), in the northern South China Sea Shelf-sea (NoSoCS) and adjacent waters is evaluated. Regional and sub-regional mechanisms in driving the coastal processes, which influence the spatial and temporal distributional patterns in water component, are assessed. Seasonal vertical convective mixing by wind and surface heating/cooling is the primary force in driving the annual changes in SST and Chl_a in the open South China Sea (SCS), in which highly negative correlation coefficients between Chl_a and SST and moderately positive correlation coefficients between Chl_a and wind speed are found. Together, the seasonal variations in SST and wind speed account for about 80% of the seasonal variation in Chl_a. In the NoSoCS as a whole, however, the contribution is reduced to about 40%, primarily due to the effect of the Pearl River plume. A tongue of water extending eastward from the mouth of the River into the middle shelf with positive correlation coefficients between Chl_a and SST and around zero or slightly negative correlation coefficients between Chl_a and wind is the most striking feature in the NoSoCS. The westward and eastward propagations of the Pearl River plume are both very small during the northeast monsoonal season, driven primarily by the Coriolis effect. The abrupt increase in the areal coverage of the River plume, which is much more pronounced in the eastward propagation, between June and August can be attributed to the prevailing southwest monsoon as well as the annual peak of the river flow. Coastal upwelling is another sub-regional phenomenon in the NoSoCS. The upwelling at the shelf edge off the Taiwan Bank may be characterized by its elevated Chl_a. Its areal coverage and average Chl_a do not vary greatly from month to month. The upwelling off the Hainan Island during the southwest monsoonal season may be characterized by its depression in SST. Its areal coverage reaches the maximum in July. Quantitatively characterizing the upwelling off Dongshan during the southwest monsoonal season is difficult and is not attempted here. The sub-regional phenomenon, activities of internal waves off the shelf break, is also assessed. Internal waves can reach the entire outer shelf- upper slope of the NoSoCS where they undergo transformation and even destruction, resulting in the depression in SST and the enhancement in Chl_a. The effect is more pronounced north of the Dongsha Atoll.

    Now in its tenth year, "In the Footsteps of Roger Revelle" (IFRR) is a middle school science education program that draws student interest, scientific content and coherence with Next Generation Science Standards from real-time research at sea in fields of physical science. As a successful collaboration involving Scripps Institution of Oceanography (SIO),Office of Naval Research (ONR), and San Marcos Middle School (SMMS), IFRR brings physical oceanography and related sciences to students at the San Marcos Middle School in real-time from research vessels at sea using SIO's HiSeasNet satellite communication system. With a generous grant from ONR, students are able to tour the SIO Ships and spend a day at sea doing real oceanographic data collection and labs. Through real-time and near-realtime broadcasts and webcasts, students are able to share data with scientists and gain an appreciation for the value of Biogeochemical research in the field as it relates to their classroom studies. Interaction with scientists and researchers as well as crew members gives students insights into not only possible career paths, but the vital importance of cutting edge oceanographic research on our society. With their science teacher on the ship as an education outreach specialist or ashore guiding students in their interactions with selected scientists at sea, students observe shipboard research being carried out live via videoconference, Skype, daily e-mails, interviews, digital whiteboard sessions, and web interaction. Students then research, design, develop, deploy, and field-test their own data-collecting physical oceanography instruments in their classroom. The online interactive curriculum models the Next Generation Science Standards encouraging active inquiry and critical thinking with intellectually stimulating problem- solving, enabling students to gain critical insight and skill while investigating some of the most provocative questions of our time, and seeing scientists as role-models. IFRR has provided students in the San Diego area with a unique opportunity for learning about oceanographic research, which could inspire students to become oceanographers or at least scientifically literate citizens, a benefit for our society at large.

  9. INTEGRAL Science Data Centre to be presented to the press

    NASA Astrophysics Data System (ADS)

    2002-03-01

    The task of INTEGRAL, the most sensitive gamma-ray observatory ever launched, will be to gather some of the most energetic radiation that comes from space. It will pinpoint and study gamma-ray sources in unprecedented detail and will help to solve some of the biggest mysteries in astronomy: INTEGRAL will investigate the origin of enigmatic gamma-ray bursts, brief but extremely powerful releases of energy, and will bring much new information on stellar explosions and black holes. Not only does INTEGRAL tell us about places where we could not live, it also tell us about the processes that made the Universe habitable, such as the formation of chemical elements. The INTEGRAL Science Data Centre (ISDC), located near Geneva, represents the key element in the exploitation and analysis of the data that will come from INTEGRAL during the two years planned for in-orbit operations. In the centre, the data will be analysed, formatted and made accessible to the worldwide astronomical community. Such fundamental work on INTEGRAL data guarantees that data can be exploited by a wide community of astronomers, including those who are not familiar with the instrumentation used for gamma-ray observations. The ISDC is supported and funded by a dozen institutes in Europe and the United States (the ISDC consortium). The press conference on 11 April marks the end of the centre's development phase and the start of its operational phase. The presence of the ISDC in Switzerland represents a particular opportunity for Swiss scientists, who will participate in a special way to the development of high-energy particle astrophysics, as a result of having privileged access to INTEGRAL data. Speakers at the press conference will include Professor T. Courvoisier (Geneva Observatory, Principal Investigator of the INTEGRAL Science Data Centre), Doctor P. Creola, (Head of Swiss Space Office), and Professor D. Southwood (Director of Science at the European Space Agency). Note to editors INTEGRAL, ESA's International Gamma-Ray Astrophysics Laboratory, will be launched in October 2002 on a Proton rocket from Baikonour, Kazakhstan. The spacecraft is currently subject to final testing at ESA's European Space Research & Technology Centre (ESTEC) in Noordwijk, the Netherlands, while the ground segment facilities - from which INTEGRAL operations will be controlled - are preparing for final review in June. The spacecraft will be shipped to the launch site in August 2002.
